    专利说明:

    The invention relates to a mechanical operating device capable of deploying or folding an aerodynamic flap used as an example in motor vehicles to modify the air intake conditions in a motor ventilation duct.
    This flap occupies a retracted position in which, the plane of the flap is integrated into a housing arranged in the plane of the bodywork with which the flap merges, and an extended position in which the flap comes to thwart the flow of air in order to deflect a portion of the flow and obtain an aerodynamic effect to reduce aerodynamic losses downstream of the flap.
    Optionally, the shutter can also serve as shutter of the ventilation duct. For example, a flap of this type can be placed under the front bumper at the entrance of the lower engine ventilation opening. Other uses employing a mobile aerodynamic flap can also be envisaged. This is the case, for example, of an air deflector placed on the roof at the level of the roof opening to improve the conditions of sound comfort when the roof opening is open or else of the flap equipping the tailgate. , or the wings, to modify the aerodynamic supports of the vehicle when the latter is traveling at high speed.
    Conventionally, the actuating mechanism of the flap comprises a motor coupled to a geared motor acting on an axis of rotation located on one of the side edges of the flap, and around which the flap pivots or toggles to move from one position to another.
    However, it is observed that this type of mechanism has several disadvantages.
    Indeed, to operate the maneuver, it is necessary to provide a relatively large power engine to generate an opening torque adapted to oppose the torque generated by the aerodynamic pressure exerted on the flap when the vehicle is traveling at a high speed. speed. The object of the invention is to limit this drawback.
    The purpose of the proposed maneuvering device is to animate in motion an aerodynamic flap disposed on a motor vehicle. This maneuvering device is characterized in that it comprises mechanical means for passing the shutter from a folded position to an extended position, making movements in a given order: leaving the shutter while retaining the shutter plane parallel to the direction of a flow of air flowing around the flap when the vehicle is in motion, so that the aerodynamic pressure exerted on the flap is substantially zero and then pivoting the flap about a pivot axis passing substantially through a center of aerodynamic thrust of the flap, so that the torque applied to the pivot axis and resulting aerodynamic forces acting on the flap is substantially zero. and reciprocally from an extended position to a retracted position by performing said movements in the reverse order.
    This deployment mode makes it possible to reduce the engine torque necessary for the only movements of exit and pivoting.
    It goes without saying that when the angle of incidence of the flap increases when the latter tilts around its pivot axis, the aerodynamic force exerted by the air on the flap also increases. Also, special means must be provided to maintain the flap in the deployed position once this movement completed.
    As will be seen later, these means can usefully be distinct from the motor element driving the mechanical device, so that the motor is only requested to ensure changes in position, and it is no longer necessary maintain the engine energized when the aerodynamic flap is in the extended position.
    Although many mechanical arrangements are conceivable for carrying out the deployment and retraction movement according to the invention, the operating device is based on original mechanical means which comprise in isolation or in combination the following characteristics: the mechanical means comprise an axis of secondary rotation, parallel to the pivot axis, around which are articulated a first rocker, connected to the aerodynamic flap, by a first rod, and whose position change causes the movement of the outlet or retraction of the flap, and a second rocker , connected to the flap by a second link, and the change of position causes the pivoting movement of the flap. the first and the second connecting rod are attached by a first and a second articulation respectively disposed at the two ends of each of the rods and whose axes are parallel to the pivot axis, to one side of the flap on the one hand and said rockers on the other hand, and projections on a plane perpendicular to the pivot axis of the axes of said joints are disposed substantially at the four corners of a deformable parallelogram. the first link is connected to the flap by its first articulation whose axis merges with the pivot axis, and the first rocker by its second articulation whose axis coincides with the secondary axis of rotation, so that the first link pivots about the secondary axis of rotation when the first rocker changes position. the second link is connected to the second rocker by its second hinge arranged radially at a given distance d of the secondary axis, and the flap by its first hinge disposed at the same distance d from the pivot axis of the flap. the positions of the rods are arranged so that a plane, passing through the secondary axis and the axis of the articulation of the second link on the second rocker, is substantially parallel to the plane of the flap. the mechanical means comprise a drive wheel rotated about a main axis parallel to the pivot axis, at least one face of the disk formed by the drive wheel comprising a pin for moving in rotation a position to another and vice versa respectively the first and the second rocker. each rocker comprises a radial slot in which a pin moves to pivot said rocker from one position to another around the secondary axis. the drive wheel comprises at least one circular locking disk, of the same axis of rotation as the drive wheel, arranged in elevation on each of the faces of the disk formed by the drive wheel having a pin, the radius of which is less than the distance to the main axis of said pin, and placed vis-à-vis at least one rocker. the drive wheel comprises two locking disks each disposed on one of the faces of the disk formed by the drive wheel, each of these faces comprising a pin, and wherein the rockers are arranged at the right of each of the locking disks, on either side of the disk formed by the drive wheel. each rocker comprises two semi-circular cutouts, respectively defining a first and a second rocker position, arranged on either side of the radial slot, each cutout having a radius equal to the radius of the blocking disc vis-à-vis which said rocker is placed. when a rocker is placed in a position, the center of a semicircular cut is disposed on the main axis, so that said rocker is locked in rotation by the locking disc in relation to which it is placed . when the first and second rocker are each placed in a given position, the torque applied to the main axis of rotation and resulting from forces acting on the flap is zero. each locking disc has a recess arranged radially to the right of the spindle, so as to allow the pivoting of the rocker when the latter changes position. the flap is in the retracted position when the first rocker is in a first position, the flap is in the extended position when the first rocker is in a second position. the flap is parallel to the flow of air flowing on the bodywork element supporting the flap when the vehicle is moving, when the second rocker is in a first position, the flap is in the rotated position, when the second rocker is in a position. second position. when the drive wheel performs an angular path less than 360 °, the respective arrangements of the rockers and the pins are adjusted angularly about the main axis so that the change of position of the first rocker is effected when the second rocker is disposed in the first position, and that the change of position of the second rocker is effected when the first rocker is disposed in the second position. the drive wheel is rotated under the action of a motor coupled to a geared motor. The invention will be better understood on reading the appended figures, which are provided by way of example and are not limiting in nature, in which: FIG. 1 is a simplified perspective view of the mechanical means selected. Figures 2, 3 and 4 show the operation of the mechanical means during the output movement of the shutter. Figures 5, 6, 7 and 8 show the operation of the mechanical means during the pivoting movement of the flap. FIG. 9 is a simplified perspective view of a maneuvering device
    The operating device illustrated in Figure 1 comprises an aerodynamic flap 1 connected by a first and a second link, respectively 21 and 22 to mechanical means designed to animate the output movement and pivoting of the flap.
    The operating device serving as a support for the present description relates to a flap located at the front of the vehicle in the lower part of the bumper. This type of aerodynamic flap alternately passes from a folded position to a deployed position in which it directs the flow of air to improve the aerodynamics of the vehicle and reduce downstream head losses. Being placed close to the ground, special attention is also paid to the speed of withdrawal to prevent the shutter is damaged by obstacles detected by a radar placed at the front of the vehicle.
    The flap comprises a center of aerodynamic thrust 10 whose location is determined, in theory, by the shape, the angle of incidence of the flap and the speed of the air flow flowing around the flap when the vehicle is moving. Although this theoretical position is variable, an average position can nevertheless be determined experimentally. This position is close to the geometric center of the flap when the latter has for example a flat shape.
    When the angle of incidence of the flap changes, the torque resulting from the resultant aerodynamic forces generated by the air flow applied around a pivot axis AA ', located substantially in the plane of the flap and passing substantially through the aerodynamic thrust center 10 is close to zero.
    The first link 21 is connected to the flap by a first articulation 210 of axis aa '. It is then arranged for the axis aa 'to be substantially coincident with the pivot axis AA passing through the center of thrust 10.
    The first rod 21 is attached by a second hinge 211 to a first rocker 23. The first rod 21 is locked in rotation relative to the first rocker 23 so that the first rod 21 and the first rocker 23 may possibly form a single piece articulated freely rotated around the axis SS '.
    The first rocker 23 pivots around a secondary axis of rotation SS 'coincides with the axis of rotation bb' of the second hinge 211 of the first rod 21. The rotational movement of the first rocker 23 around the axis SS ' thus causes the rotational movement of the first rod 21 around the same axis. The axis SS 'is parallel to the pivot axis AA. This axis is fixed in the reference formed by the vehicle.
    The flap 1 is also connected to the mechanical means by a second link 22. The second link 22 is connected to the flap by a first articulation 220 of axis CC 'parallel to the pivot axis AA' and distant from this axis of a length d. The other end of the second link is connected by a second hinge 221, of axis dd 'parallel to the pivot axis AA', a second rocker 24, 24a. The second rocker is articulated freely in rotation around the secondary axis SS '. The axis dd 'is distant from the secondary rotation axis SS' by a distance d.
    It will be observed here that the plane of the shutter can be likened to the plane passing through the axes AA 'and cc'. Also, to obtain the best effects, we will try to reduce the size of the joints 210 and 220 as much as possible, so that the distance between the plane passing through the axes AA and cc ', similar to the plane of the flap, and a plan parallel to this plane and passing through the center of aerodynamic thrust, corresponding substantially to the average plane of the flap, is the lowest possible. When the flap has a more or less curved shape to fit the profile of the bodywork, this average plane can be defined, experimentally so as to dispose accordingly axes AA 'and cc'.
    The second rocker 24 may comprise a transfer arm 24a, fixed on the second rocker 24, at the end of which is positioned the hinge 221 with the second link 22. The transfer arm 24a is locked in rotation relative to the second rocker 24. The second rocker 24 and the transfer arm 24a can also form a single piece.
    It is then arranged that the distances between the axes of the first and the second articulation of each of the links are substantially identical, so that the projection on a fictional plane P, perpendicular to the pivot axis AA, axes SS '(aa'), bb ', cc' and dd 'form a deformable parallelogram p.
    The plane of the flap is therefore substantially parallel to a plane passing through the secondary axis SS 'and the axis dd'.
    As will be explained in detail later, under the action of the first rocker 23, the rotation of the first link around the axis SS 'controls the output movement of the flap. By keeping the second rocker in a fixed position around the secondary rotation axis SS ', the plane of the flap occupies, during the exit movement, successive positions which are all parallel to one another.
    This fictitious plane can usefully be adjusted to be parallel to the direction of the flow of air flowing over the bodywork element supporting the flap when the vehicle is in motion, so that the aerodynamic pressure exerted on the flap during the outward movement is substantially zero. The motor force is reduced to the forces necessary to generate the rotational movement of the first rocker.
    Once the flap is released, and by maintaining fixed the position of the first rocker, the rotation of the second rocker 24 around the axis SS 'causes the pivoting movement of the flap around the pivot axis AA. As has been mentioned above, this axis AA 'passes substantially through the center of aerodynamic thrust 10, so that the necessary torque transmitted by the second link 22 to pivot the flap about the axis AA' is low.
    The mechanical means illustrated in Figure 2 also comprise a drive wheel 25 of radius R, driven in rotation about a main axis of rotation XX 'by a motor assembly (not shown). The main axis of rotation is parallel to the pivot axis AA '. This axis is also fixed in the reference formed by the vehicle.
    The face 251 of the disc formed by the drive wheel 25 supports a pin 253 extending axially from the face 251, and disposed at a distance r3 from the main axis of rotation XX '. The first rocker 23 is disposed on the side of the face 251 supporting the pin 253. This first rocker comprises a slot 230 oriented radially relative to the secondary axis of rotation SS '. The first rocker 23 is arranged so that, when the drive wheel is rotated, the pin 253 enters the slot 230 and drives the first rocker in rotation about the secondary rotation axis SS '. The first rocker then moves from one position to another. Continuing the rotation of the drive wheel pin 253 out of the slot 230 on the first rocker.
    Turning the drive wheel in the opposite direction allows the rocker to return to the previous position according to the same principles as those stated above.
    The drive wheel also comprises, on the same face 251 as that which supports the spindle 253, a locking disk 26, of axis XX 'arranged in elevation with respect to the plane formed by the face 251. This locking disc has a radius n, smaller than the distance r3 separating the pin from the axis XX '.
    The first rocker 23 comprises two semicircular cutouts 231 and 232, of the same radius n as the locking disk 26, and disposed on either side of the slot 230.
    The first rocker 23 is then arranged so that, when occupying a given position, the center of a semi-circular cut is placed on the main axis XX '. The outer edge of the semi-circular cutter then bears against the locking disk, which prevents rotation of the rocker about its axis and keeps the latter in its position when the drive wheel and the locking disk continue their rotation. around the XX 'axis.
    The locking disk 26 also comprises a recess 260, arranged at the right of the spindle 253, whose dimensioning is adjusted so as to allow the rotation of the rocker 23 when the latter is engaged by the spindle 253 and rotates around the spindle 253. SS 'axis when changing position.
    The two semi-circular cutouts, respectively 231 and 232, thus define a first and a second position occupied by the first rocker 23. These two positions are stable. The angular difference between these two positions is defined geometrically by the distance between the main axis of rotation SS 'and the main axis XX', by the radius n of the locking disc, and by the position r3 of the spindle. This angular difference is adjusted so that the rotation of the first rocker 23 from one position to another causes the passage of the flap of the folded position in which the flap is retracted, at the output position.
    The above indications apply mutatis mutandis to the second rocker 24 which controls the movement of the rod 22 and the pivoting of the flap about the axis AA '.
    With substantial changes in the mechanism, the rocker 24 could be located on the same face 251 as the rocker 23. However, preferably, there will be the second rocker 24 on the side of the face 252 of the disk formed by the drive wheel 25, and opposed to the face 251. The second rocker 24 is also articulated around the secondary axis of rotation SS '.
    The radius r2 of the locking disk 27 (not visible in FIG. 1) disposed in elevation of the face 252, the radial positioning r4 of the pin 254 flowing in the slot 240 (not visible in FIG. 1) of the second rocker 24 and disposed on the face 252, may optionally be identical or not, respectively to the radius n or r3.
    The radii of the semi-circular cutouts 241 and 242 (not visible in Figure 1) will be adapted accordingly.
    The respective angular positions of the pins 253 and 254 around the main axis XX 'are adjusted so that, when the drive wheel makes an angular path less than 360 °, the change of position of the first rocker 23 is effected when the second rocker 24 is disposed in the first position, and that the change of position of the second rocker 24 is performed when the first rocker 23 is disposed in the second position.
    These original mechanical means make it possible, on the one hand, to respect, by construction, the kinematics of the respective movements of output and of pivoting as described above, and to ensure, on the other hand, that the rotation of the first rocker 23 is blocked by the blocking disk 26 before starting the pivoting of the flap around the pivot axis. Indeed, as already mentioned, although the torque required to perform this movement is theoretically negligible, the aerodynamic pressure exerted on the flap increases considerably during pivoting, and a large torque around the axis SS 'is exerted on the first rocker 23 which supports the first rod 21.
    When this first rocker 23 is in the second position, its movement is blocked by the disk 26, and it will then be observed that the torque exerted by these aerodynamic forces on the axis XX ', which is the motor axis, is zero.
    To increase the foldback speed of the shutter it is even possible to initiate the rotational movement of the first rocker 23 attached to the first rod 21 slightly before the end of the pivoting movement of the flap by adjusting accordingly the respective angular positions of the pins 253. and 254.
    The folding movement of the flap is done by reversing the direction of rotation of the drive wheel which successively causes the pivoting of the flap in the opposite direction so as to place the plane of the flap in a position parallel to the direction of flow of the flap. air, then the return of the shutter.
    Thus, the deployment movement and the folding movement of the flap are done by rotating the drive wheel less than 360 °. This allows in particular to fold the flap extremely quickly in case of detection of an obstacle that could damage it.
    Figures 2, 3 and 4 illustrate the output movement of the shutter 1. In Figure 2, the flap 1 is in the folded position and its plane is substantially parallel to the air flow F flowing around the bodywork element when the vehicle is moving and on which it is attached. The first rocker 23 is in the first position and its rotation about the axis SS "is blocked by the engagement of the disc 26 in the semi circular cut 231. The second rocker is also in the first position, so that the plane flap is parallel to the air flow.
    The drive wheel 251 is rotated, and the pin 253 enters the slot 230 of the first rocker, forcing it to rotate about the axis SS ', as shown in Figure 3. The recess 260 frees a space allowing the first rocker 23 to pass from the first to the second position.
    The first rod 21 rotates about the axis SS 'and causes the rotation of the second rod 22 about the axis cc', which brings the flap 1 in the extended position as shown in Figure 4.
    The second rocker 24 is maintained in its first position, and the flap 1 always remains parallel to the air flow F.
    When the first rocker 23 is in the second position, the disk 26 engages the semicircular cutout 232. The first rocker 23 and the first rod 21 are then locked in this second position.
    Figures 5, 6, 7 and 8 illustrate the kinematics of the pivoting of the flap about the pivot axis AA '.
    FIG. 5 illustrates the operating device seen from the side of the face 252, in the extended position illustrated in FIG. 4. The locking disk 27 is engaged in the cutout 241 of the second rocker 24 and keeps the latter in the first position.
    By continuing the rotation of the drive wheel in the same direction as before, the pin 254 engages the radial slot 240 of the second rocker 24 as shown in Figure 6, and the recess 270 frees the space allowing the second rocker 27 to rotate about the secondary rotation axis SS '.
    The second rocker 24 then passes from the first to the second position as illustrated in FIG. 7. The second link 22, whose hinge axis on the second rocker 24 is off-center by a given distance d, makes turn the flap 1 around the pivot axis AA.
    The torque applied to the drive wheel 25 is reduced to the only torque necessary to overcome the friction. Which are not negligible because of the pressure exerted by the disk 26 on the first rocker 23 to maintain it in the second position.
    By continuing its rotation, the disc 27 engages the semi-circular cut 242, and blocks the second rocker 24 in the second position as shown in FIG. 8.
    It is observed here that the second link 22 is connected to the second rocker 24 via a transfer arm 24a. This transfer arm is secured to the second rocker by a fixed connection so that the transfer arm 24a is locked in rotation relative to the second rocker 24. This assembly was chosen for reasons of space and to accommodate a bearing supporting the secondary rotation shaft of the axis SS '. Also, as already mentioned, the transfer arm 24a and the second rocker 24 could equally well form a single piece.
    Figure 9 illustrates the operating device disposed on the lower wall of a front bumper 4 of a motor vehicle, and placed in the deployed position in which the flap is extended and pivoted. The device is mounted on a stirrup 5 connected to the chassis of the vehicle. The stirrup 5 supports the shaft carrying the secondary rotation axis SS ', and the shaft carrying the main axis XX'. The latter is connected to a drive motor 3 by means of a geared motor 31 to drive the wheel 25 in rotation in one direction or another.
    The maneuvering device as described above can have many adaptations when the aerodynamic flap is disposed on other parts of the vehicle.
    It is thus possible to control the movement of each of the rockers with the aid of two independent drive wheels, driven in rotation by two separate geared motor groups, while maintaining a geometric arrangement in which the axes of the joints form a deformable parallelogram. It is then possible to make rockers having more than two semi-circular cuts and can occupy, by rotating the drive wheel several times around the main axis, a plurality of intermediate positions between each of the extreme positions. This arrangement can be particularly interesting when one seeks for example to regulate the aerodynamic pressure exerted on the shutter by acting on its angle of incidence, while minimizing the consumption of motive power to pass the shutter. one position to another.
    All these mechanisms make it possible to respect the operating principles that are the subject of the invention, which have the particular advantage of being low energy consumers.
