    [0001] The present invention relates to a vehicle front lift hood device that raises the front end portion of a hood.
    [0002] As a vehicle front lift cover device that raises the front end portion of a hood, there is the device disclosed in Japanese Patent Application Laid-open No. JP-A No. 2004-249872. In this vehicle-up front hood device, reinforcements are arranged in the vicinity of the outer sides in the widthwise direction of the vehicle of an open portion in a radiator support, and the actuating devices are fixed by intermediate supports on back surfaces reinforcements. Additionally, when the actuators are activated, keeper members disposed at the two side sections in the vehicle width direction of the front end portion of the hood move upwardly. As front liftable vehicle hood devices that lift the front end portion of a hood, there are also the devices disclosed in JP-A Nos. 2004-299614, JP-A No. 2006199179, and JP. -A No. 2006-518016. Furthermore, as devices where actuators are attached via the supports to a vehicle body, there are the devices disclosed in JP-A No. 2009-202863, JP-A No. 2012 -071705, and JP-A No. 2013203240. In the front lift vehicle hood device described in JP-A No. 2004-249872, the structure through which the brackets are attached to the reinforcements is as follows. That is, a pair of fastening portions adjacent to each other in the vehicle width direction is formed at each of the supports, and the pairs of fastening portions are attached to the back surfaces of the reinforcements. For this reason, when the actuators are activated, the activation loads of the actuators act on the back surfaces of the reinforcements, and there is a risk that the reinforcements may be deformed in such a way that the parts upper end of the actuating devices are shifted in the front-rear direction of the vehicle.

The second wall portions extend outwardly in the vehicle width direction from the rear ends of the first wall portions and are arranged with their plate thickness direction coinciding with the vehicle front-rear direction, and the supports are attached to the front surfaces of the second wall portions. For this reason, the first wall portions and the second wall portions are connected to each other by the supports, and closed cross-sections resulting from the first wall portions, second wall portions, and supports are formed as seen in a plan view. For this reason, the actuators are attached to the radiator support sides and, at the same time, the radiator support sides are reinforced. A third aspect of the present invention is the vehicle front lift hood device of the first aspect or the second aspect, wherein deformation boxes ("crash box") attached to front end portions of front side members are disposed at the lower side of the vehicle supports, and lower ends of the supports are fixed on the deformation boxes.
    [0007] In the vehicle front lift hood device of the third aspect, the radiator support sides are connected to the deformation boxes by the supports, so that the reinforcing effect of the radiator support sides is further improved. A fourth aspect of the present invention is the vehicle front lift hood device of the first aspect or the second aspect, wherein front side members are disposed extending in the vehicle front-rear direction at a lower vehicle side of the supports, and lower ends of the supports are attached to front end portions of the front side members. In the vehicle lift front hood device of the fourth aspect, the radiator support sides are connected to the front side members by the brackets, so that the reinforcing effect of the radiator support sides is further enhanced. According to the vehicle front lift hood device of the present invention, the accuracy with which the hood is lifted by the actuators is improved. According to the vehicle front lift hood device of the present invention, the actuating devices are attached to the radiator support sides and at the same time the radiator support sides are reinforced.

    [0011] The hood latch body 60 is disposed on the vehicle front side of the latch base 44 and is formed in a generally rectangular shape as seen in a front view. The hood latch body 60 is rotatably supported at its right side end portion of the vehicle on the support axis 48 of the latch base 44. For this reason, the latch body hood 60 can rotate relatively in the vertical vehicle direction (the directions of arrow A and arrow B in Fig. 4) relative to lock base 44 about support axis 48. Furthermore, a guide pin 62 is disposed at the vehicle left side end portion of the hood latch body 60, and the guide pin 62 is formed in a cylindrical shape and protrudes from the hood latch body 60 towards the rear side of the vehicle with its axial direction coinciding with the front-rear vehicle direction. Additionally, the guide pin 62 is slidably inserted into the guide hole 50 in the locking base 44.
    [0012] In addition, an anchor recess portion 64 is formed in the upper portion of the hood latch body 60 in a position on the vehicle front side of the exhaust recess portion 46 of the latch base 44. The anchor recess portion 64 is formed in a groove shape that opens toward the vehicle top side, and the width dimension of the anchor recess portion 64 is set to become larger in size. pointing towards the upper side of the vehicle. Additionally, in the closed position of the hood 12, the anchor portion 14A of the hood striker member 14 is disposed within the lower end portion of the anchor recess portion 64. Furthermore, a latch 66 is disposed at the hood latch body 60. Additionally, the anchor portion 14A of the latch striker member 14 disposed within the lower end portion the anchoring recess portion 64 is configured to be held by the latch 66. In addition, a cable is connected to the latch 66, and when the cable is actuated, the anchor portion 14A is released from the hold by the latch 66. latch 66. Fastening plate 70 has a substantially fan-shaped shape as viewed in a front view and is disposed on the vehicle front side of hood latch body 60. Fastening plate 70 is rotatably connected. , at its level by base end portion, at the lock base 44 by a support pin 72, the axial direction of which coincides with the front-rear direction of the vehicle. Furthermore, the curved section of the outer peripheral portion of the fixing plate 70 serves as a contact surface 74, and the contact surface 74 is in the shape of an arc whose axial center coincides with the center of the axis The contact surface 74 is in contact with a cylindrical attachment pin 52 disposed at the hood latch body 60, and in this state, the rotation of the hood latch body 60 toward the upper side of the vehicle. (the side in the direction of the arrow A in Figure 4) is regulated. On the other hand, one end of a cable 76 is anchored to the attachment plate 70, and the other end of the cable 76 is anchored to a link mechanism 79 (see Fig. 2) engaged to the actuator described above. Later, when the cable 76 is pulled to the left-hand side of the vehicle, the mounting plate 70 is rotated counter-clockwise to the left side of the hood latch device 42. Additionally, shows as seen in a front view so that the contact surface 74 of the attachment plate 70 is released from contact with the attachment pin 52. For this reason, the hood lock body 60 becomes rotatable to the upper vehicle side (the side in the direction of the arrow A in Figure 4), so that the front end portion of the hood 12 can be raised. An exhaust portion 68 is formed in the hood latch body 60 and mentioned above is configured in such a manner that, when the hood latch body 60 rotates, the hood latch body 60 does not interfere with the fixing plate 70 and the support pin 72. In addition, the fixing plate 70 is pushed in a clockwise direction as seen in a front view by a spring 78. ( Actuating Devices 80) As shown in FIG. 1, the actuators 80 are each formed in a substantially cylindrical shape whose axial direction coincides with the vertical vehicle direction and are disposed in the vicinity of the support sides. In particular, the actuating devices 80 are arranged on the outer sides in the vehicle width direction of the side wall portions 24 of the radiator support sides 22 and on the front side. 3 and the rear side portions 26 of the radiator support sides 22 and are disposed at the upper side of the vehicle deformation boxes 32 and front side members 30. For this reason, the first fixed surfaces 24A of the parts 24 and the second fixed surfaces 26A of the rear wall portions 26 are arranged by stepping over the actuators 80. Additionally, the actuators 80 are attached to the radiator support sides 22 by the intermediate supports 90 described later. As shown in Fig. 5, the actuators 80 each have an actuator body 82 arranged with a substantially cylindrical shape. On the other hand, the actuators 80 have a substantially cylindrical cylinder portion with a bottom 84 which opens towards the lower vehicle side, and the upper portion of the actuator body 82 is inserted into the interior of the vehicle. the cylinder portion 84. Additionally, in a state in which the actuators 80 are not activated, the upper end portions of the cylinder portions 84 are disposed slightly spaced from the hood 12 to the lower side of the vehicle. (see Figure 2). An enlarged diameter portion 82A protruding outwardly in the radial direction of the actuator body 82 is integrally formed at the upper portion of the actuator body 82, and the outer diameter of the enlarged diameter portion 82A is provided larger than the outer diameter of the actuator body 82. A groove portion 82Aa is formed in the outer circumferential portion of the enlarged diameter portion 82A along the circumferential direction of the actuator body 82. An O-ring 86 is attached to the groove portion 82Aa, and the gap between the enlarged diameter portion 82A and the cylinder portion 84 is sealed by the O-ring 86. In addition, a gas generator 88 is mounted within the actuator body 82 in the middle portion lengthwise. The gas generator 88 is provided with a primer (an ignition device), and the gas generator 88 is filled with a gas generating agent. On the other hand, the gas generator 88 is electrically connected to an electronic control unit (ECU) 36 (see FIG. 2) and is configured to be activated by the control of the electronic control unit 36. When the gas generator 88 is activated, gas generated by the gas generator 88 is delivered to the interior of the actuator body 82. As a result, the cylinder portion 84 rises due to the gas pressure in the device body. actuator 82 and the portion of the cylinder portion 84 engages the hood 12, such that the forward end portion of the hood 12 is urged to a lifting position (the position indicated by the mixed in Figure 2).
    [0013] Furthermore, a wiring harness 89 connected to the gas generator 88 is directed through the radial direction inside the actuator body 82, and the wiring harness 89 is extended through the lower end of the housing body. actuator 82 outside the actuator 80. The radial direction within the actuator body 82 is filled with resin. In addition, as shown in FIG. 2, a linkage mechanism 79 is engaged with the cylinder portion 84 of the actuator 80 disposed on the left vehicle side of the hood latch device 42, and the other The end of the cable 76 mentioned above is anchored to the link mechanism 79. Additionally, when the cylinder portions 84 are lifted when the actuators 80 are activated, the link mechanism 79 is activated and the cable 76 is activated. is pulled to the left side of the vehicle. Furthermore, a collision detection sensor 38 shown in FIG. 3 and a collision prediction sensor are electrically connected to the aforementioned electronic control unit 36. The collision detection sensor 38 has a relatively long pressure tube 38A whose lengthwise direction coincides with the vehicle width direction, and the pressure tube 38A is disposed adjacent to the front surface of the reinforcement Furthermore, pressure sensors 383 are disposed at the two end portions in the direction of the steering length of the pressure tube 38A, and signals corresponding to a pressure change at the end of the pressure tube 38A. Inside the pressure tube 38A are delivered to the electronic control unit 36 by the pressure sensors 38B. The collision detection sensor 38 may be configured by (or may include) a pressure chamber or an optical fiber. As a collision prediction sensor, a pre-crash sensor that uses a millimeter-wave radar and a stereoscopic camera to predict a collision with a colliding body such as a pedestrian can be used. Additionally, the electronic control unit 36 judges whether or not to activate the actuators 80 based on signals that have been acquired from the collision detection sensor 38 and the collision prediction sensor. . (Supports 90) As shown in Fig. 3, the pair of supports 90 fixes the actuators 80 on the radiator support 20 as mentioned above. The pair of supports 90 is disposed in correspondence with the actuators 80 in the vicinity of the radiator support sides 22. The pair of supports 90 is configured to be in bilateral symmetry with respect to the other, thus, the support 90 disposed at the right side of the vehicle will be described, and a description of the support 90 disposed on the left side of the vehicle is omitted. The support 90 shown in Figure 1 and Figure 6 is made of a steel plate. The support 90 comprises a support body portion 92 which is connected to the above-mentioned actuator 80, a first attachment portion 94, a second attachment portion 96, and a third attachment portion 98. The portion of Support body 92 is folded into a generally curved L shape as viewed in a plan view and extends in the vertical vehicle direction. On the other hand, the support body portion 92 is disposed on the radial direction outer side of the actuator body 82 as viewed in a plan view, and the bend portion of the support body portion 92 is formed. in a substantially circular arc shape as viewed in a plan view so as to follow the outer peripheral surface of the actuator body 82. Additionally, the actuator body 82 is connected by welding or equivalent to the bent portion of the support body portion 92. For this reason, the actuating device 80 is integrated with the support 90.
    [0014] The first attachment portion 94 extends to the vehicle front side from the inner end in the vehicle width direction of the upper portion of the support body portion 92 and is disposed along the first fixed surface 24A. of the side wall portion 24 of the radiator support side 22 with its plate thickness direction coinciding with the vehicle width direction. On the other hand, a top and bottom pair of first attachment holes are formed by penetrating the first attachment portion 94 in the vehicle width direction, and bolts B1 are inserted within the first attachment holes. Additionally, the bolts B1 are screwed into weld nuts WN1 disposed at the inner surface in the vehicle width direction of the sidewall portion 24, and the first fastening portion 94 is thereby secured to the first one. fixed surface 24A of the side wall portion 24. The second attachment portion 96 extends outward in the vehicle width direction from the rear end of the upper portion of the support body portion 92 and is disposed along the second stationary surface 26A of the rear wall portion 26 of the radiator support side 22 with its plate thickness direction coinciding with the vehicle front-rear direction. On the other hand, an upper and lower pair of second fixing holes is formed by penetrating the second fixing portion 96 in the vehicle front-to-rear direction, and bolts B2 are inserted into the second fixing holes. Additionally, the bolts B2 are screwed into weld nuts WN2 disposed at the rear surface of the rear wall portion 26, and the second fastening portion 96 is thus secured to the second stationary surface 26A of the housing portion. For this reason, the zone (i.e., the first fixed surface 24A) of the radiator support side 22 where the first fixing portion 94 is fixed and the zone (i.e. say the second fixed surface 26A) of the radiator support side 22 where the second fixing portion 96 is fixed are configured to be different wall surfaces. In addition, the side wall portion 24 and the side wall portion 26 of the radiator support side 22 are connected to each other by the support 90, so that a closed section 100 (see FIG. ) resulting from the side wall portion 24, the side wall portion 26 and the support 90 is formed as viewed in a plan view. The third attachment portion 98 extends to the opposite side of the actuator body 82 from the lower end of the support body portion 92 as seen in a plan view and is disposed along the an upper wall 32A of the deformation box with its plate thickness direction coinciding with the vertical vehicle direction. A pair of third attachment holes are formed by penetrating the third attachment portion 98 in the vertical vehicle direction, and bolts B3 are inserted within the third attachment holes. Furthermore, soldering nuts corresponding to the third fixing holes are arranged at the lower surface of the upper wall 32A of the deformation box. The bolts B3 are screwed into the nuts to be welded, and the third fixing portion 98 is thus fixed on the upper wall 32A (see Figure 1). For this reason, the rear end portion of the deformation box is connected to the radiator support side 22 by the support 90.
    [0015] The action and effects of the present embodiment will then be described. When the lift cover device 40 is not activated, the cover 12 is placed in the closed position and the engine compartment ER is closed by the cover 12 (see the cover 12 indicated by the solid line in FIG. 2). From this state, when the vehicle 10 is involved in a frontal collision with a colliding body such as a pedestrian, the frontal collision with the colliding body is detected by the collision detection sensor 38 and a signal is delivered by the collision detection sensor 38 at the electronic control unit 36. The electronic control unit 36 judges whether or not to activate the lift front hood device 40 based on the signal that has been inputted.
    [0016] Then, when the electronic control unit 36 determines that the liftable hood device 40 is to be activated, the gas generators 88 of the actuators 80 are activated by the control of the electronic control unit 36 and the gas. is delivered inside the actuator bodies 82. When the gas is delivered inside the actuator bodies 82, the cylinder parts 84 are pushed by the gas pressure inside the actuator bodies 82. actuator body 82 and move (ascend) in the axial direction toward the vehicle top side along the axial direction of the actuator bodies 82. When the cylinder portions 84 move in the axial direction towards the upper side of the vehicle, the cable 76 of the liftable hood device 40 is pulled towards the left side of the vehicle at the same time as the movement of the cylinder parts 84. For this reason, the Fastener 70 rotates and the hood latch body 60 becomes rotatable toward the upper side of the vehicle. In other words, it becomes possible for the front end portion of the hood 12 to be raised. On the other hand, when the cylinder parts 84 are moving in the axial direction towards the upper side of the vehicle, the upper end portions of the cylinder parts 84 come into contact with the hood 12 and lift the front end portion of the hood. 12 towards the upper side of the vehicle. For this reason, the front end portion of the hood 12 is pushed to the raised position (see the broken line in Figure 2). Here, the supports 90 integrated with the actuating devices 80 are fixed on two wall surfaces (the first fixed surfaces 24A and the second fixed surfaces 26A) of the radiator support sides 22. More specifically, the first attachment portions 94 of the The supports 90 are fixed to the first fixed surfaces 24A of the radiator support sides 22, and the second attachment portions 96 of the supports 90 are fixed to the second fixed surfaces 26A which are different from the first fixed surfaces 24A of the radiator support sides. 22. As a result, compared to a case where the first attachment portions 94 and the second attachment portions 96 are attached to a side wall surface of the radiator support sides 22, a deformation of the radiator support sides 22 when the actuating devices 80 are activated is avoided. That is, assuming a case where the first attachment portions 94 and the second attachment portions 96 of the brackets 90 are secured to the first fixed surfaces 24A (or the second fixed surfaces 26A) of the support sides. 22, the first attachment portions 94 and the second attachment portions 96 would be disposed adjacent to each other on the first fixed surfaces 24A (or the second fixed surfaces 26A). Then, when the actuating devices 80 are activated, the activating charges or forces of the actuating devices 80 would be applied only to the first fixed surfaces 24A (or the second fixed surfaces 26A), so that the charges of activation would then be received by a wall surface of the radiator support sides 22. For this reason, there is a risk that the side wall portions 24 (or the rear wall portions 26) will be deformed at the zones where the first attachment portions 94 and the second attachment portions 96 are attached thereto, such that, for example, the upper end portions of the actuating devices 80 are offset in the vehicle width direction (or the direction front-rear of vehicle). In contrast, in the present embodiment, the regions of the radiator support sides 22 where the first fastening portions 94 and the second fastening portions 96 are secured are different wall surfaces (the first fixed surfaces 24A and the second fixed surfaces 26A). For this reason, when the actuators 80 are activated, the activation loads of the actuators 80 are applied to both the first fixed surfaces 24A and the second fixed surfaces 26A. That is, the activation loads of the actuators 80 are received by different wall surfaces of the radiator support sides 22. Therefore, compared to a case where both the first parts of The attachment 94 and the second attachment portions 96 are attached to a side wall surface of the radiator support sides 22, a deformation of the radiator support sides 22 when the actuators 80 are activated is controlled. As a result, an offset of the upper end portions when the actuators 80 are activated is controlled, so that the cylinder portions 84 of the actuators 80 are lifted (activated) to their activated set positions. . As a result, the accuracy with which the hood 12 is pushed up by the actuators 80 is improved. On the other hand, the first fixed surfaces 24A form the outer surfaces in the vehicle width direction of the side wall portions 24 of the radiator support sides 22, and the second fixed surfaces 26A configure the front surfaces of the rear wall portions 26 of the Radiator support sides 22. For this reason, the closed sections 100 that result from the sidewall portions 24, rear wall portions 26, and brackets 90 are formed by attaching the brackets 90 to the radiator support sides 22. As a result, the actuators 80 are attached to the radiator support sides 22 and at the same time the radiator support sides 22 are reinforced. In addition, the radiator support sides 22 are reinforced by the supports 90 without having to use separate elements to reinforce the radiator support sides 22. For this reason, the weight of the vehicle 10 is reduced while the cost of the vehicle 10 is prevented from increasing. On the other hand, the torsional rigidity of the entire radiator support 20 is improved by reinforcing the radiator support sides 22 with the supports 90.
    [0017] In addition, the third attachment portions 98 of the supports 90 are fixed to the upper walls 32A of the deformation boxes 32. For this reason, the upper portions of the radiator support sides 22 are connected to the deformation boxes 32 by the supports 90. , so that the reinforcing effect of the radiator support sides 22 is further improved. In addition, by connecting the upper portions of the radiator support sides 22 to the deformation boxes 32 through the supports 90, a deformation of the radiator support sides 22 such as the upper end portions of the support sides of the radiator 22 radiator 22 shift in position in the vehicle front-rear direction is controlled. As a result, for example, the directional stability of the vehicle 10 when the vehicle 10 is moving is improved. That is, as the vehicle 10 moves, upward and downward forces are applied to the front side members 30, so that the front end portions of the front side members 30 tend to shift in position in the vertical direction of the vehicle. At this time, the radiator support sides 22 tend to deform in such a manner that the upper end portions of the radiator support sides 22 shift in position in the front-to-rear direction of the vehicle. In contrast, in the present embodiment, as described above, the upper portions of the radiator support sides 22 are coupled to the deformation boxes 32 by the supports 90, so that deformation of Radiator support 22 as described above is controlled. For this reason, a displacement of the front end portions of the front side members 30 in the vertical vehicle direction when the vehicle 10 is moving is controlled, so that the directional stability of the vehicle 10 is improved. On the other hand, the first attachment portions 94 and the second attachment portions 96 of the supports 90 are formed at the upper end portions of the supports 90, and the third attachment portions 98 of the supports 90 are formed at the portions of the brackets 90. lower end of the supports 90. That is, the supports 90 are configured to be attached at their upper end portions and their lower end portions. As a result, an offset of the upper end portions of the actuators 80 when the actuators 80 are activated is effectively controlled.
    [0018] In the present embodiment, the radiator support sides 22 are configured to include the side wall portions 24 and the rear wall portions 26, but the shape of the radiator support sides 22 is not limited thereto. For example, the plane sectional shape of the radiator support sides 22 may be formed with a substantially hat shape that opens outward in the width direction of the vehicle, and the open end portions of the sides of the radiator support 22 may be configured to be connected to the inner side walls in the vehicle width direction of the front side members 30. That is, front wall portions which extend to the Outside in the width direction of the vehicle from front ends sidewall portions 24 may be added to the radiator support sides 22, and the outer end portions in the vehicle width direction of the front wall portions and rear wall portions 26 may be configured to be connected to the inner side walls in the vehicle width direction of the front side members 30. In this the second attachment portions 96 of the brackets 90 may be attached to the front wall portions or the rear wall portions 26 of the radiator support sides 22, and the third attachment portions 98 may be attached to upper walls of the front side members 30. Further, in the present embodiment, the deformation boxes 32 are attached to the front end portions of the front side members 30 through the rear wall portions 26 of the support sides. 22, but the deformation boxes 32 may also be omitted. That is, the front end portions of the front side members 30 may be configured to be attached to both end portions in the vehicle width direction of the bumper reinforcement 34. this case, as described above, for example, the planar sectional shape of the radiator support sides 22 may be formed substantially hat-shaped which opens outwardly in the width direction of the vehicle, and the open end portions of the radiator support sides 22 may be configured to be connected to the inner side walls in the vehicle width direction of the front side members 30. In addition, in this case, the third Fixing portions 98 of the supports 90 may be attached to upper walls of the front side members 30. In this case also, the reinforcing effect of the radiator support sides 22 is further improved. Therefore, directional stability as the vehicle moves is improved. On the other hand, in the present embodiment, the first fixed surfaces 24A and the second fixed surfaces 26A of the radiator support sides 22 are formed as flat surfaces, but portions of the first fixed surfaces 24A and the second fixed surfaces 26A can be formed. also overtake.
    [0019] For example, the areas of the side wall portions 24 of the radiator support sides 22 on which the first attachment portions 94 of the brackets 90 are fixed may also protrude outwardly in the vehicle width direction because they have been subjected to stamping, traction or the like. On the other hand, in the present embodiment, the center portion in the vehicle width direction of the front end portion of the hood 12 is configured to be locked by the hood latch device 42 of the lift hood device. Instead, the two end portions in the vehicle width direction of the front end portion of the hood 12 may be configured to be locked by the liftable hood device 40.
    [0020] On the other hand, in the present embodiment, the actuators 80 comprise the actuator bodies 82 and the cylinder portions 84 in which the upper portions of the actuator bodies 82 are inserted, but the present embodiment is not limited to this. The actuators 80 may also be formed by the actuator bodies 82 and piston rods housed within the actuator bodies 82.30.
