The power supply device 1 according to the present embodiment electrically connected, in a vehicle 5 having a vehicle body 60 and a sliding door 50, the vehicle body 60 and the sliding door 50 via a cable harness 110 mounted between they. In FIG. 1, the right side corresponds to the front face of the vehicle 5, the left side to the rear face of the vehicle 5, the upper side to the outside of the vehicle 5 and the lower side to the inside of the vehicle 5. In addition, in the present embodiment, the vertical direction in the figure is the X direction, in the present embodiment the horizontal direction in the figure is the Y direction and the direction perpendicular to the paper surface is the Z direction.
In the power supply device 1, the power supply is supplied by a power source, not shown, located in the vehicle body 60, connected to an electrical device (not shown) located in the sliding door 50. through the cable harness 110. In addition, in the electrical device 1, electrical signals are also exchanged between a control means (not shown) located in the vehicle body 60, and an electrical device (not shown) located in the vehicle. sliding door 50, via the cable harness 110. The electrical device 1 comprises the cable harness 110, a corrugated tube 120, a curvature restriction member 130, a door-side holding member 140, and a side holding member 140. vehicle body 150.
The cable harness 110 is formed by the union of a plurality of electrical cables 111, and the flexible resin corrugated tube 120 passes through a portion of the cable harness 110, between the vehicle body 60 and the door The curvature restriction element 130 is arranged between an inner surface of the corrugated tube 120 and the cable harness 110, surrounding the cable harness 110 in the circumferential direction, so as to follow the cable harness 110. Curvature restriction element 130 is described in detail below.
An end of the corrugated tube 120 on the side of the sliding door 50 is pivotally held on the door side holding member 140 in the XY plane, with the vertical direction Z of the vehicle 5 as the direction of the shaft. pivoting. The door side holding member 140 is attached to the sliding door 50. The door side pivoting shaft 141 located in the door side holding member 140 along the Z direction is a shaft parallel to the door sliding 50 and perpendicular to the opening / closing direction D11 of the sliding door 50 (the Y direction which is the longitudinal direction of the vehicle 5). One end of the corrugated tube 120 on the side of the sliding door 50 is pivotally held about the door-side pivot shaft 141 by the door-side holding member 140. The corrugated tube 120 is held by the member The door-side holding member 140 allows the cable harness 110 to be rotated about the door-side pivot shaft 141 in the XY plane. The cable harness 110 on the side of the sliding door 50 exits an end of the corrugated tube 120 on the side of the sliding door 50. In addition, after being pulled out of the holder element from the door side 140 through a passage shown inside this door-side holding member 140, the cable harness 120 extends to an electrical equipment of the sliding door 50.
On the other hand, one end of the corrugated tube 120 on the side of the body of the vehicle 60 is pivotally held on a holding element of the vehicle side 150 in the XY plane, with the vertical direction Z of vehicle 5 as the direction of the pivot axis. The vehicle body side support member 150 is attached to the vehicle body 60. The vehicle side body pivot shaft 151 located in the vehicle side body hold member 150 along the Z direction is a shaft parallel to the sliding door 50 and perpendicular to the opening / closing direction D11 of the sliding door 50. An end of the corrugated tube 120 of the body side 60 is pivotally held around the pivot shaft of the sliding door 50. the side of the vehicle 151 by the vehicle body side holding member 150. Maintaining the corrugated tube 120 by the body side holding member 150 allows the cable harness 110 to be held on the XY plane around the pivot shaft of the vehicle side 151. One side of the cable harness on the side of the sliding door 50 exits an end of the corrugated tube 120 on the side of the vehicle 60 and passes to ravers a passage not shown inside the holding element of the body side 150 before extending to a power source and a control means not shown in the vehicle body 60.
As shown in FIG. 1, when the sliding door 50 is completely closed, the door-side holding member 140 is positioned on the front side of the vehicle 5 with respect to the vehicle side 150 holding member. The corrugated tube 120, and thus the cable harness 110 placed therein extends substantially linearly between the body side holding member 150 of the vehicle and the door side holding member 140.
In the initial stage where the sliding door 50 opens in an opening direction D11l facing the rear of the vehicle 5, an end of the corrugated tube 120 located on the side of the sliding door 50 pivots in the following manner. This end pivots in the XY plane so as to be separated from the sliding door 50 and moves towards the front side of the vehicle 5 in a direction opposite to the opening direction D111. The door side holding member 140 is provided with a coil spring to facilitate this pivoting. This coil spring separates the end of the corrugated tube 120 located on the sliding door 50 side of the latter, the orients in the direction of displacement D12 and moves in the opposite direction to the opening direction D11l of the sliding door 50.
Because of the pivoting described above in the initial stage of the opening of the sliding door 50, the cable harness 110 inside the 120 folds in the following manner during the movement of the door 50 in the opening direction D111, that is to say when the sliding door 50 is half open. The cable harness 110, as shown in FIG. 1, is folded in the allowable direction D13 and bent from the body side holding member 150 to the door side holding member 140 so as to form in the XY plane a convex U of the front side of the vehicle 5 , towards the outside of the vehicle body 60.
In the following description, the cable harness 110 located inside the corrugated tube 120 may be called simply "the cable harness 110".
Compared to the case of curvature of the corrugated tube 120 where the cable harness 110 is S-shaped, for example, the U-shaped curvature as described above reduces the load transmitted to the corrugated tube 120 or cable harness 110.
When the sliding door 50 moves in the opening direction D111, the leg of the U formed by the cable harness 110 on the side of the sliding door 50 is pressed in the direction of movement D12 in the holding member the door side 140 to extend linearly towards the front of the vehicle 5. The branch on the side of the vehicle body 60 is then pressed to extend linearly towards the front of the vehicle 5. The behavior of these parts and the Operation of the curvature restriction member 130 which is described below shortens the U-shape in the XY plane of the cable harness 110 during movement of the sliding door 50.
When the sliding door 50 moves in the opening direction D111, the U-shaped leg formed by the cable harness 110 on the side of the sliding door 50 extends and the branch on the side of the vehicle body 60 shortens. When the branch on the side of the body 60 has shortened by a certain length, one end of the cable harness 110 on the side of the vehicle body 60 pivots in the direction D15 toward the rear of the vehicle 5. After that, in this state, the sliding door 50 moves in the opening direction D111 and opens fully.
When the sliding door 50 closes in the closing direction DI 12 from the fully open position, the operation of 1x0 cable harness is reversed with respect to its operation when the sliding door 50 opens. First, at the initial stage, one end of the cable harness 110 on the side of the vehicle body 60 pivots in the opposite direction to the pivoting direction D15, so that the cable harness 110 adopts a U shape in the XY plane. Then, at the stage where the sliding door 50 continues to move in the closing direction DI 12 and the U-branch located on the side of the sliding door 50 is shortened by a certain length, one end of the cable harness 110 on the other side. of the sliding door 50 pivots in the following manner. At this point, one end of the cable harness 110 located on the side of the sliding door 50 pivots by opposing the displacement force of the holder element of the door side 140, toward the rear of the vehicle 5, at the opposite of the direction of travel D12. Then, still in this state, the sliding door 50 moves in the closing direction DI 12 and the cable harness 110 reaches the fully closed position by extending linearly.
Here, the end portion of the floor of the vehicle body 60 on the side of the sliding door 50 is lowered by one level and becomes a step 61 on which the passenger places his feet on entering. Upon opening and closing the sliding door 50, as described above, the U-shaped leg of the cable harness 110 on the side of the vehicle body 60 near the step 61 in the XY plane .
In this case, in general, concerning the power supply device attached to the sliding door of the vehicle, there is a request to remove the bulge to the side of the vehicle body when the cable harness bends to the opening and closing of the door. Therefore, in the present embodiment, in order to adjust the curvature that projects the cable harness 110 on the side of the vehicle body 60, the bend restriction element 130 is arranged along the cable harness 110. The curvature restriction member 130 limits the curvature in the XY plane with respect to the cable harness 110. The curvature restriction element 130 allows the curvature in the allowable direction D13 to fold the cable harness 110 to the cable harness 110. outside the vehicle body in the XY plane. On the other hand, the curvature in a predetermined limit state or beyond in the adjusting direction D16, folding the cable harness 110 inside the vehicle body 60 on the opposite side to the allowable direction D13, is adjusted.
[0041] FIG. 2 is a perspective view showing the curvature restriction element shown in FIG. 1.
As shown in FIG. 1, the curvature restriction member 130 is disposed between the inner surface of the corrugated tube 120 and the cable harness 110, surrounding the cable harness 110 in the circumferential direction and along the harness 110 so as to guide its curvature. The bend restriction member 130 is substantially the same length as the corrugated tube 120. In FIG. 2, the curvature restriction element 130 on the right is on the side of the vehicle body 60 and the end portion on the left side of the sliding door 50.
The curvature restriction element 130 comprises a plurality of parts 131 arranged along the cable harness 110 and a connecting portion 132 which interconnects the adjacent parts among the plurality of parts 131. In the present form of FIG. realization, the plurality of parts 131 and the connecting portion 132 are molded in one block. In FIG. 2, one can see the curvature restriction element 130 following the U-shaped bent wire harness 110 in the allowable direction D13 in the XY plane shown in FIG. 1. The connecting portion 132 is a flexible member arranged along the cable harness 110 so as to be located within the curve when the cable harness is bent.
FIGS. 3A and 3B show one of the plurality of parts constituting the curvature restriction member of which a typical example is shown in FIG. 2. FIG. 3A is a perspective view of the element 131 and FIG. 3B a cross-sectional view taken along the line Vll-VII in FIG. 3A.
As shown in the representative example in FIGS. 3A and 3B, each of the plurality of pieces 131 comprises a pair of opposite walls 1311 opposed to each other so as to sandwich the cable harness 110, and a connecting wall 1312 connecting the opposite walls 1311 therebetween. The three walls of each of the pieces 131 are substantially C-shaped as shown in FIGS. 3A and 3B, the cross section which intersects the longitudinal direction D17 of the cable harness 110.
As shown in FIG. 3A, each of the opposed walls 1311 of the pair is substantially T-shaped in plan view. A portion corresponding to the transverse bar of the T extending in the longitudinal direction D17 of the cable harness 110 is narrow, and the portion corresponding to the vertical bar of the T crossing the longitudinal direction D17 is narrow and short. The root of the narrow portion of each of the opposing walls 1311 T-shaped is connected to the connecting wall 1312. The connecting wall 1312 connects these narrow parts.
Furthermore, the opposite surface of the cable harness 110 in each of the opposite walls 1131 of the pair has an irregular shape in which reinforcing ribs 1311a are assembled in the form of a lattice. In addition, the envelope shape of the outer surface provided by the reinforcing ribs 1311a is a curved convex surface along the inner surface of the corrugated tube 120. The two end surfaces 1311b of the width of each opposing wall 1311 in the longitudinal direction D17 are substantially wedge-shaped, as are the lateral surfaces of the reinforcing ribs 1311a.
The plurality of parts 131 is arranged along the cable harness 110 so that the wedge-shaped end faces 1311b of the opposite walls 1311 of each piece 131 face each other.
In the present embodiment, the plurality of parts 131 is arranged so that the connecting wall 1312 connecting the pair of opposing walls 1311 is positioned within the curve of the cable harness 110, namely to the inside of the curve when the harness is bent in the admissible direction D13 as shown in FIG. 2. The connecting portion 132 interconnects the connecting walls 1312 mutually adjacent pieces 131. On the other hand, the connecting portion 132 is a flat member, as shown in FIG. 3A, with such a thickness that it can bend in the admissible direction D13 as well as in the opposite direction. Further, the curvature restriction member 130 is configured such that the flat connection portion 132 is configured as shown in FIG. 1 so as to be perpendicular to the XY plane. Therefore, the curvature restriction element 130 is restricted in the XY plane, so that the curvature of the cable harness 110 is also restricted in the XY plane.
Furthermore, in the present embodiment, the end of the curvature restriction member 130 on the right side of FIG. 2, i.e., the piece 131a located at the end of the side of the vehicle body 60, is held on the body side holding member 150 of the vehicle shown in FIG. 1 with the end portion of the corrugated tube 120. On the other side, in the bend restriction member 130, the left end portion in FIG. 2, i.e., the piece 131b at the end of the side of the sliding door 50 is not held by the door-side holding member 140 shown in FIG. 1. As a result, the piece 131b can separate from the door-side holding member 140 depending on the curvature of the bend restriction member 130. As shown in FIG. 2, the part 131a on the side of the body of the vehicle 60 is provided with a flange 131a-1 to hold it in the holding element of the body side of the vehicle 150.
[0051] FIG. 4 is a view showing a state in which the body side curvature restriction member piece is held by the body side holding member of the vehicle; it is a schematic cross-sectional view taken along line V12-V12 in FIG. 1.
The body side of the support element 150 of the vehicle comprises a fastener 152 attached to the vehicle body 60 and a pivoting part 153 pivotally supported around the pivot shaft of the vehicle body side 151 also shown in FIG. 1. In the pivoting part 153 is provided an insertion hole 153a through which the cable harness 110 passes, this insertion hole 153a opening on the side of the sliding door 50. The end of the corrugated tube 120 on the side of the body of the vehicle 60 is fixed at the opening 153b of the pivoting part 153. Furthermore, on the back of the opening 153b is formed a fixing groove 153c in which the collar 131a-1 of the 131a of the curvature restriction member 130 on the side of the vehicle body 60 exposed from the end portion of the side of the vehicle body of the corrugated tube 120 is fixed. Due to the attachment of the collar 131a-1 in this fixing groove 153c, the vehicle side member 60 of the bend restriction member 130 is held on the body side holding member of the vehicle 150 with the end portion of the corrugated tube 120. It should be noted that the vehicle body side holding member 150 may be provided with an actuating member such as a coil spring which actuates the pivot piece 153 in the direction opposite to the pivoting direction D15 shown in FIG. 1. Actuation by this actuating element plays an auxiliary role by linearly extending the cable harness 110 on the side of the vehicle body 60 towards the front of the vehicle 5.
As indicated above, the curvature restriction element 130 on which the end piece 131a is held is restricted to the curvature in the XY plane shown in FIG. 1, and can also be folded in the admissible direction D13. The curvature restriction element 130 can not be bent beyond the limit described hereinafter, in the inward direction of adjustment of the vehicle body 60, on the opposite side to the allowable direction D13.
FIGS. 5A and 5B provide a state in which the curvature restriction element can be bent in the allowable direction shown in FIG. 1 and can not be bent beyond the limit state in the restricted direction opposite the limit state. FIG. 5A shows that the curvature restriction element 130 can be bent in the allowable direction D13. FIG. 5B shows that the curvature restriction element 130 can not be bent beyond the limit state in the adjustment direction D16.
In the allowable direction D13, as shown in FIG. 5Λ, the parts adjacent to each other among the plurality of pieces 131 at a curved portion are spaced apart from each other on the opposite side to the connecting portions 132 when the connecting portions 132 are folded, and therefore the restriction member of curvature 130 can be folded. Therefore, the HIClHlIlIlcllSlGIlS SG pilGr duSlS Here direction eligible D13.
On the other hand, in the adjusting direction D16, as shown in FIG. 5B, the parts adjacent to each other among the plurality of parts 131 at the curved portion abut one another on the opposite side to the connecting portion; therefore, curvature restriction element 130 can not be bent beyond the limit state. At this curved portion, the curvature restriction element 130 can not bend in the restriction direction D16 beyond this limit state where the state in which the adjacent parts are in contact with each other is limited in the curvature in the direction of adjustment D16. As a result, the cable harness 110 is restricted in the curvature beyond the limit state of the member 130 in the direction of adjustment D16.
In this embodiment, except for a part near the body side holding element 150 of the vehicle 150 which is described below, concerning the direction of arrangement (that is to say the longitudinal direction D17 of the cable harness 110) of the plurality of pieces 131, the curvature restricting member 130 is configured over the entire length, including its central portion, as follows. Generally over the entire length of the portion described above, the curvature restriction member 130, as shown in FIG. 5B, is configured such that the adjacent pieces 131 abut each other on the opposite side to the connecting portion 132 when in a substantially linear state. In other words, in the present embodiment, the limit state in the direction of adjustment D16 is a substantially linear state, except on the part near the body side holding member 150 of the vehicle. the cable harness 110 other than a curved portion in the permissible direction D13 to be maintained in a substantially linear form.
Here, as shown in FIG. 1, in the present embodiment, with respect to the adjusting direction D16, the pivoting range in the XY plane of the end portion of the cable harness 110 in the vehicle body side holding member 150 is as follows . This pivoting range is such that the end portion of the cable harness 110 stops one step before the cable harness 110 is advancing parallel to the opening and closing direction DU of the sliding door 50. Therefore, in the In this embodiment, with respect to a proton in the vicinity of the vehicle body side holding member 150, the bend restriction member 130 is configured to be able to bend by slightly releasing the adjustment against curvature in the direction D16 and up to a certain point in the direction of adjustment D16. Therefore, the portion of the cable harness 110 near the body side holding member 150 of the vehicle 150 is slightly bent in the direction of adjustment D16, and the portion held in a substantially linear shape as indicated above is configured to advance in the direction parallel to the opening and closing direction DU of the sliding door 50.
FIGS. 6A and 6B are perspective views showing a curved restriction member of the cable harness showing how restriction of curvature in the adjustment direction of the cable harness 110 is slightly relaxed in the portion near the holding member of the cable harness side of the vehicle. FIG. 6A is a view showing a curvature restriction member 130 on which the portion of the cable harness 110 near the vehicle body side holding member 150 is in a substantially linear state. FIG. 6B shows how the additional curvature is set by the curvature restriction element 130 when the aforesaid portion of the cable harness 110 is bent to a certain extent in the adjusting direction D16.
As shown in FIG. 6A, in the curvature restraining member 130, the length LU of the piece 131c in the direction D17 of the cable harness 110 near the body side holding member 150 of the vehicle is substantially shorter than the length L12 131. Accordingly, with respect to the portion near the body side holding member 150, even when the bend restriction member 130 is in a substantially linear state, the spaces d11 and d12 are open between the parts 131c and 131. Therefore, with respect to this portion shown in FIG. 6B, until the adjacent parts 131c, 131 contact each other on the opposite side of the connecting portions 132 to close the spaces d11, d12, the connecting portions 132 fold in the adjusting direction D16 . This curvature of the connecting portions 132 allows the adjusting member 130 to bend to a certain extent in the direction of adjustment D16. This allows the adjustment of the curvature of the cable harness 110 to be slightly relaxed in the adjustment direction D16 at the portion near the body side holding member 150 of the vehicle. The state shown in FIG. 6B becomes a limit state of the portion of the curve restricting element 130 located near the body side holding member 150 of the vehicle.
As indicated above, in the present embodiment, a space between the plurality of pieces 131, the curvature restricting member 130 being substantially straight, i.e. curved, or in the allowable direction D13 or in the adjustment direction D16, differs in the arrangement direction (longitudinal direction D17). That is, as shown in FIG. 5B, on a portion extending substantially the entire length except for the portion near the holding member of the body side of the vehicle 150, the space between the pieces 131 is substantially zero, and in the vicinity of the body side holding member 150, as shown in FIG. 6A, the spaces d11 and dl2 are open. Therefore, at two points of said portion and at the other portion located near the body side holding member 150 of the vehicle 130 in the curvature restriction member 130, the limit state with respect to the curvature in the adjustment direction D16 differs from the description above.
The curvature restriction element 130 of the first embodiment described above is foldable in the admissible direction D13 described above. On the other hand, in the restriction direction D16 of the opposite side, the pieces adjacent to each other among the plurality of pieces 131 on a curved portion are brought into contact with each other on the opposite side to the connecting portions 132 which prevent curvature. In the power supply device 1, the curvature restriction element 130 is then arranged in the cable harness 110 so that the curvature restriction element 130 becomes operable in a desired direction to adjust the curvature of the harness. As a result, the curvature of the cable harness 110 can be adjusted in the desired direction as the adjusting direction D16. Therefore, at the moment of opening and closing of the sliding door 50, the cable harness 110 preferably positioned in the following manner near the vehicle body 60.
[0063] FIG. 7 is a cross-sectional view taken along the line V13-V13 in FIG. 1 showing a state in which the cable harness is located in a preferred position near the vehicle body at the time of opening and closing the sliding door.
As indicated above, in the portion of the cable harness 110 corresponding to the branch of the U which is formed on the side of the vehicle body 60 when the sliding door 50 opens and closes, the curvature in the direction The inwardly facing control gear D of the vehicle body 60 is restricted by the curvature restriction member 130. The cable harness 110, the curvature of which is set in this manner in FIG. 7 is positioned slightly outside a step 61 of the vehicle body 60, with the corrugated tube 120 and the curvature restriction element 130. As indicated above, in the present embodiment, the harness Cables 110 is prevented from bulging towards step 61 inside vehicle body 60 when sliding door 50 opens and closes.
Furthermore, in the present embodiment, in the plurality of parts 131 forming the curvature restriction element 130, the adjacent parts are in contact with each other on the opposite side to the connecting portions 132 when the curvature restricting member 130 is in a substantially linear state, at least in the middle of the curvature restricting member 130.
In the power supply device 1, which approaches the step 61 is the middle of the cable harness 110 when the sliding door 50 opens and closes. With the curvature restriction element 130 according to the present embodiment, with respect to the portion along the middle of the cable harness 110, the curvature in the adjustment direction D16 is rendered almost zero, thereby substantially eliminating the bulge of the cable harness 110 as indicated above.
Furthermore, in the present embodiment, the space between the plurality of parts 131 of the curvature restriction element 130, when the latter is in a substantially linear state, folded or in the admissible direction D13 nor in the adjustment direction D16, is defined to be different between the part near the body side holding member of the vehicle 150 and the other parts. Therefore, the limit state of the curvature restriction element 130 with respect to the curvature in the adjustment direction D16 differs at these two locations in the arrangement direction of the plurality of pieces 131. Therefore, when the bend restriction member 130 is bent at each limit state in the adjusting direction D16, the shape is not a linear shape or a pure circular arc, but a shape as shown in FIG. 1, corresponding to the interval at each place. As indicated above, in the present embodiment, the shape when the curvature restriction member 130 is curved in the limit state in the restriction direction D16 is defined as desired depending on the installation conditions. cable harness 110 in the power supply device 1.
The shape of curvature in the limit state as described above is arbitrarily defined at the design stage as a function of the setting of the gap between the plurality of pieces 131. For example, according to the shape that it is desired to take the cable harness 110 (the form shown in FIG.1 in the present embodiment) when a bending force is applied to the cable harness 110 in the adjusting direction D16, desired interval can be defined at the design stage. Thus, the definition of the interval between the pieces 131 at the design stage makes it possible to create the desired shape when the harness is bent to the limit state in the direction of adjustment D16 as indicated above.
Furthermore, in the curvature restriction member 130 according to the present embodiment, the plurality of pieces 131 and the connecting portions 132 are integrally molded. Therefore, it is unnecessary to assemble the curvature restriction element 130 or the like, which reduces the cost of manufacture.
Furthermore, in the curvature restriction element 130 according to the present embodiment, each of the plurality of parts 131 is provided with a pair of opposed walls 1311 facing each other with the harness 110 interposed therebetween. and a connecting wall 1312 connecting the pair of opposing walls 1311 to each other. Therefore, each piece 131 has a substantially C-shaped cross-section that intersects the longitudinal direction D17 of the cable harness 110. As a result, for example, the bend restriction member 130 easily follows the cable harness 110 of the cable harness 110. such that the cable harness 110 is covered by each piece 131 having a substantially C-shaped cross-section.
In the present embodiment, as indicated with reference to FIG. 1, at the initial stage of the opening of the sliding door 50, the cable harness 110 quickly adopts a shape of U. This form of U is produced by moving the vehicle 5 away from the sliding door 50, in a direction opposite to the DI 11 opening direction. Therefore, a coil spring which acts on the cable harness 110, separating it from the sliding door 50 and orienting it in a direction opposite to the opening direction D111 of the sliding door 50, is mounted with the door side holding member 140. However, the structure that triggers the pivoting movement of the cable harness 110 at the initial stage of opening the sliding door 50 as indicated above is not limited to coil springs; the next alternative structure is also imaginable.
FIGS. 8A and 8B are views showing a structure for pivoting the cable harness when the sliding door opens, using a coil spring or other device. FIG. 8A is a schematic view showing the structure of the door side holding member 140 integrated in the power supply device 1 according to the present invention. FIG. 8B is a diagram showing the structure of the door side holding member 140 'of another example. In FIG. 8B, the same parts of the door-side holding member 140 'as those of the present embodiment shown in FIG. 8A bear the same reference numbers.
As shown in FIG. 8A, the door-side holding member 140 of the present embodiment has a fastener 142 attached to the door 50 and a pivotable portion 143 pivotally mounted about the door-side pivot shaft 141 in the fastener 142 also shown in FIG. 1. The end portion of the corrugated tube 120 on the side of the sliding door 50 covering the cable harness 110 is fixed to the pivoting portion 143, the portion of the cable harness 110 on the side of the sliding door 50 being held on the pivoting portion 143. A coil spring 144 is disposed around the pivot shaft of the door side 141. This coil spring 144 allows the pivoting portion 143 and therefore the cable harness 110 to move in an actuating direction D12 so that away from the sliding door 50 and being oriented in a direction opposite to the opening direction D11l to the front of the vehicle 5. This coil spring 144 triggers the pivoting of the cable harness 110 in the direction D12.
On the other hand, the door side holding member 140 'of another example shown in FIG. 8B does not have the tilting coil spring described above. Instead, there is a restriction member 145 for adjusting the position of the cable harness 110 around the door-side pivot shaft 141. This restriction member 145 adjusts the front-side position in the direction of opening D111 of the sliding door 50, around the pivot shaft of the door side 141 in the following manner when the sliding door 50 is fully open. The restriction member 145 adjusts this position so that the cable harness 110 and the sliding door 50 form an acute angle Θ greater than a predetermined angle around the door-side pivot shaft 141. This position adjustment is performed when the sliding door 50 is oriented in the closing direction DI 12 by the restriction member 145 regulating the pivoting of the cable harness 110 in the pivoting direction D18 to the position where the cable harness 110 and the sliding door form the angle acute Θ above.
In the door side holding member 140 'of this alternative example, when the sliding door 50 completely closes, the cable harness 110 and the sliding door 50 form the acute angle 0 around the pivoting of the door side 141 and the cable harness 110 is inclined to a certain extent with respect to the sliding door 50. Therefore, when the sliding door 50 is opened, the cable harness 110 rotates rapidly in a direction D19 in which the angle of inclination with respect to the body of the vehicle 60 opens, and curves substantially U-shaped of the vehicle body 60 towards the side of the sliding door 50. In such a cable harness 110, in In combination with the adjustment by the curve restricting element 130 during the movement of the sliding door, the linear shape of the vehicle body side portion 60 corresponding to a branch U i is satisfactorily maintained. you. Therefore, during the movement of the sliding door 50, the bulge of the cable harness 110 to the vehicle body 60 can be further adjusted.
Furthermore, in the door-side holding element 140 'of this other example, the rapid pivoting of the cable harness 110 as described above when the sliding door 50 opens is restricted by the adjustment in the Restriction member 145. Thus, the actuating spring or the like is unnecessary for pivoting the cable harness 110, and therefore, its structure can be simplified.
Thus ends the explanation of the first embodiment of the present invention, including its alternative example, and we will now describe the second embodiment of the present invention.
In the second embodiment, the curvature restriction element differs from the curvature restriction element 130 of the first embodiment described above. In contrast, the structure and other characteristics of the power supply device are the same as those of the power supply device 1 of the first embodiment. Therefore, the second embodiment of the present invention will be described hereinafter by attaching to the curvature restriction element, and the description of the points identical to those of the first embodiment such as the structure. the power supply device will be omitted.
FIG. 9 is a view showing a curvature restriction element according to the second embodiment of the present invention. Incidentally, in this FIG. 9, various types of directions or other cable harness and deformation of the cable harness accompanying the opening and closing of the sliding door are the same as in the first embodiment, and the same reference numbers as on the FIG. 1 to 8 are used. In addition, in the description of FIG. 9, various elements such as the sliding door equivalent to those of the first embodiment are designated without regard to the figure number! this also applies to FIG. 10 described later.
As in the first embodiment, the curvature restriction element 230 of the second embodiment is placed between the inner surface of the corrugated tube 120 and the cable harness 110 so as to surround the cable harness 110. in the circumferential direction. The bend restriction member 230 is substantially the same length as the corrugated tube 120. In FIG. 9, the right end of the bend restriction member 230 is on the side of the vehicle body 60 and the left end is on the side of the sliding door 50.
The curvature restriction element 230 comprises a plurality of parts 231 arranged along the cable harness 110 and a connecting portion 232 which interconnects the adjacent parts among the plurality of parts 231. Also in this form of FIG. embodiment, the plurality of parts 231 and the connecting portion 232 are molded from a block salt resin. In FIG. 9 the curvature restriction member 230 is shown curved in the same U-shape as the U-shaped curved wire harness 110 in the allowable direction D13 in the XY plane shown in FIG. 1. The connecting portion 232 is a flexible element arranged along the cable harness 110 so as to be located inside the curve when the cable harness 110 is bent, that is to say at the inside of the curve when it is bent in the admissible direction D13 as shown in FIG. 9.
FIGS. 10A and 10B are views showing one of the plurality of pieces constituting the curvature restriction member shown in FIG. 9. FIG. 10A is a perspective view of the part 231 and FIG. 10B shows a cross-sectional view taken along the line V21-V21 in FIG. 10A.
As shown in the representative example of FIGs. 10A and 10B, each of the plurality of pieces 231 includes a pair of opposite walls 2311 opposed to each other and holding the cable harness 110 sandwiched therebetween, and a connecting wall 2312 connecting the pair of opposed walls 2311 therebetween. Each of the pieces 231 has three walls that are arranged substantially C-shaped as shown in FIGS. 10A and 10B, the cross section which intersects the longitudinal direction D17 of the cable harness 110.
As shown in FIG. 10A, an opposing wall 2311a of the pair of opposing walls 2311 is a rectangular plate which is narrow in the longitudinal direction D17 of the cable harness 110 and thin. On the other hand, the other opposite wall 2311b is formed as a rectangular plate broad in the longitudinal direction D17 and thick. One of the opposing walls 2311a faces a substantially central portion in the longitudinal direction D17 of the other opposite wall 2311b.
The connecting wall 2312 connects the lower part of an opposite wall 2311 in the figure and the lower part of the opposite other wall 2311b in the figure. This connecting wall 2312 is substantially T-shaped in plan view from above. Part of the cable harness 110 corresponding to the crossbar of the T T extending in the direction D17 is wide and a portion corresponding to the vertical bar of the T intersecting the longitudinal direction D 17 is short and narrow. The narrow part of the connecting wall 2312 is connected to the lower part of the opposite wall mentioned above in the figure and the wide part of the connecting wall 2312 is connected to the lower part in the figure of the other opposite wall 2311 b .
In the present embodiment, the plurality of parts 231 is arranged along the cable harness 110 so that, in each piece 231, the end face of the inverted L shape 2313 is connected continuously with the wide of the connecting wall 2312, the opposite wall 2311b having a large thickness to the wide portion of the connecting wall 2312.
In the present embodiment, the parts 231 are arranged so that the narrow and thin opposite wall 2311a of the pair of opposing walls 2311 is within the element rhe, restriction curvature 230 shown in FIG. 9. The connecting portion 232 interconnects the narrow and thin opposed walls 2311a of the pieces 231 adjacent to each other. In addition, the connecting portion 232 is flat, as shown in FIG. 10A, and thin so as to be sufficiently flexible to be able to bend in the allowable direction D13 shown in FIG. 9 or in the opposite direction. In the present embodiment, the connecting portion 232 is formed to have the same thickness as the narrow and thin opposed wall 2311a.
Still in this embodiment, the right end portion of the curvature restriction member 230 in FIG. 9, i.e., the piece 231a located at the end of the vehicle body side 60, is held on the body side holding portion 150 of the vehicle shown in FIG. 1 with the end portion of the corrugated tube 120. In addition, on the bend restriction member 230, the left end portion in FIG. 2, i.e., the part 231b located at the end of the side of the sliding door 50, is not held by the holding portion of the door side 140 shown in FIG. 1. As shown in FIG. 9, this piece 231a is provided with a flange 231a * 1 to maintain the piece 231a on the retaining piece of the body side of the vehicle 150. The retaining structure of this flange 231a-1 is equivalent to the holding structure of the first embodiment shown in FIG. 4.
The curvature restricting member 230 of the second embodiment, also similar to the curvature restricting member 130 of the first embodiment, is pliable in the allowable direction D13 and operable beyond the curvature restriction element 130 of the first embodiment. limit state in the restriction direction D16 opposite to the permissible direction D13. The fact that it is impliable is due to the fact that the inverted L-shaped end faces 2313 of the adjacent pieces 23 are in contact with each other when the cable harness 110 curves in the direction of adjustment D16. On the bend restriction member 230 of the second embodiment, similar to the restriction member 130 of the first embodiment, the gap between the pieces 231 is different in the body side portion of the first embodiment. vehicle 60 and in the other part, which defines different limiting conditions.
The curvature restriction element 230 may, even if it is replaced by the curvature restriction element 130 of the first embodiment, adjust the bulge inwardly of the vehicle body 60 into the restriction direction D16.
It should be noted that the embodiment described above is only a representative form of the present invention, and that the present invention is not limited to this embodiment. In other words, various modifications can be made without departing from the scope of the present invention. Since the configuration of the curvature restriction element and the power supply device according to the presentation is preserved by these modifications, these are within the scope of the present invention.
For example, in the embodiment described above, the curvature restriction elements 130 and 230 for causing the bending of the cable harness by inserting the corrugated tube 120 with the cable harness 110 are given as examples of curvature restriction elements according to the present invention. However, the curvature restriction element referred to herein is not limited thereto, and for example, it is possible to cause the curvature of the cable harness securing it with a cord, tie, or the like. In this case, the power supply device can be configured without corrugated tube.
In addition, in the embodiment described above, bending restriction elements according to the present invention are given as bending restriction members 130 and 230 in which a plurality of pieces 131, 231 are formed. connected to each other by thin plates such as the connecting portions 132, 232. However, the curvature restriction element referred to in the present invention is not limited thereto, and may be, for example, for example, a bar having the shape of the connection portion, the physical appearance of which does not matter.
In addition, in the embodiment described above, bending restriction members according to the present invention are given bending restriction members 130 and 230 in which a plurality of pieces 131, 231 and the connecting portions 132, 232 are integrally molded from resin. However, the curvature restriction element referred to in the present invention is not limited thereto, and may be, for example, comprised of a plurality of resin parts and a flexible connecting portion. composed of a metal leaf spring, connected by screwing, gluing, insert molding or other.
In the embodiment described above, examples of curvature restriction elements according to the present invention are bending restriction elements 130 and 230 in which the gaps between the parts 231 are different in the part. located on the side of the body of the vehicle 60 and in the other part, which defines different limit states of curvature in the direction of adjustment D16. However, the curvature restriction element according to the present invention is not limited to this, and for example, the gap of the pieces 231 can be the same and only one limit state can be defined, or different limit states can be defined. be defined in three or four places. In fact, as indicated above, the curvature restriction element, and thus the curvature of the cable harness in its direction of adjustment, can be of any shape.
In addition, in the embodiment described above, is given as an example of a method for differentiating the limit state of curvature in the direction of adjustment D16 that of differentiating the interval of the pieces 131 by differentiating the length of the plurality of pieces 131 in the arrangement direction as shown in FIG. 6. However, the aforementioned method for differentiating the limit state is not limited thereto, and a method may be adopted in which the pieces are of the same length, but where the intervals between them are different. Whatever the method, at the design stage, an appropriate definition of the limit state in two or more places of the curvature restriction element allows it to be given the desired shape in the direction of adjustment.
In the embodiment described above, are given as examples of parts according to the present invention parts 131 and 231 whose pair of opposite walls and the connecting wall form, in cross section, substantially a C. the parts to which reference is made in the present invention are not limited thereto, and may, for example, be parts forming, in cross-section, substantially an L. The specific form of the parts referred to in FIG. The present invention is of little importance if the adjacent pieces separate from each other when the cable harness bends in the permissible direction and come into contact with each other as the cable harness bends in the direction of adjustment.
