[0030] In the description of this embodiment, the terms "upper", "lower", "right", "left" and other directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0031] See also Figures 1 to 5 The present embodiment provides a vehicle component driving device, which is used to actuate a vehicle component on a vehicle that can rotate around the vehicle body. The present embodiment is described by taking the side door 210 of the vehicle as an example. The side door 210 is hinged to the vehicle body through a first hinge 211 and a second hinge 212. The first hinge 211 and the second hinge 212 are coaxially arranged, and the axis of the first hinge 211 and the second hinge 212 is a first hinge axis a, that is, the first hinge axis a is the hinge axis between the side door 210 and the vehicle body.

[0032] Based on the above, the vehicle component driving device includes a mounting shell 110, a support rod 120, a moving block 130 and a driving member 140, wherein the mounting shell 110 is fixedly connected to the side door 210, one end of the support rod 120 is hinged to the vehicle body, specifically, one end of the support rod 120 is hinged to the side panel mounting bracket on the vehicle body, the second hinge axis b is the hinge axis between the support rod 120 and the vehicle body, the first hinge axis a is parallel to the second hinge axis b, the other end of the support rod 120 is hinged to the moving block 130, specifically, the other end of the support rod 120 is rotatably connected to the moving block 130 through a ball head 151 and a ball socket 152, so that the support rod 120 can rotate freely relative to the moving block 130, and the driving member 140 is installed on the mounting shell 110, and is configured to drive the moving block 130 to move so as to adjust the distance between the moving block 130 and the second hinge axis b.

[0033] During the movement of the moving block 130 , one end of the support rod 120 connected to the moving block 130 can move with the moving block 130 , so that a driving force arm is formed between the support rod 120 and the first hinge 211 and the second hinge 212 , thereby causing the side door 210 to rotate.

[0034] When the stiffness of the first hinge 211 is low or when the user violently opens and closes the side door 210, causing the side door 210 to fall relative to the vehicle body, when the driving member 140 drives the moving block 130 to move, since multi-degree-of-freedom adjustment can be performed between the support rod 120 and the moving block 130, the support rod 120 can adaptively adjust its own posture to ensure that there is no jamming between the support rod 120 and the vehicle body and / or between the support rod 120 and the moving block 130, thereby ensuring that the side door 210 does not get stuck during the opening and closing process.

[0035] It is understandable that, in other optional embodiments, the vehicle component driving device mentioned above can also be used for vehicle components such as a vehicle tailgate and an engine hood, and this embodiment does not impose any specific limitation on this.

[0036] Based on the above, the utility model enables the other end of the support rod 120 to be rotatably connected to the moving block 130 through the ball head 151 and the ball socket 152, so that the support rod 120 can rotate freely relative to the moving block 130. When the stiffness of the hinge installed between the vehicle component and the vehicle body is low or when the user violently opens or closes the vehicle component, when the driving member 140 drives the moving block 130 to move to open or close the vehicle component, since multiple degrees of freedom can be adjusted between the support rod 120 and the moving block 130, the support rod 120 can adaptively adjust its own posture, thereby ensuring that there is no jamming between the support rod 120 and the vehicle body and / or between the support rod 120 and the moving block 130, thereby ensuring that the vehicle component will not be jammed during the switching process.

[0037] In addition, in this embodiment, the vehicle component driving device further includes a damper 170, which is directly connected to the moving block 130 by transmission, so as to brake the moving block 130 during the movement of the moving block 130, thereby enabling the side door 210 to hover, so as to meet the corresponding needs of the user and improve the user's experience. It can be understood that in this embodiment, there is no transmission ratio between the damper 170 and the moving block 130, so as to avoid amplifying the resistance generated by the damper 170 during the transmission process, that is, this embodiment can achieve hovering without increasing the force that the user needs to apply to the side door 210 when manually closing or opening the side door 210, thereby providing great convenience for the user.

[0038] Furthermore, the vehicle component driving device also includes a transmission module 160, which is transmission-connected between the driving member 140 and the moving block 130, so that the driving member 140 can drive the moving block 130 to move, so as to adjust the distance between the moving block 130 and the second hinge axis b, thereby opening or closing the side door 210.

[0039] Exemplarily, the transmission module 160 includes a gear 161 and a screw rod 162, and the gear 161 is sleeved on the outer periphery of the screw rod 162. The driving member 140 can drive the gear 161 to rotate around its axis, thereby driving the screw rod 162 to rotate around its axis. It can be understood that the screw rod 162 is rotatably connected to the mounting shell 110, and the position of the screw rod 162 along its axial direction is fixed, and the moving block 130 is screwed to the screw rod 162. When the screw rod 162 rotates, the moving block 130 can move along the axial direction of the screw rod 162, and drive the support rod 120 connected to one end of the moving rod to move along the axial direction of the screw rod 162, thereby forming a driving force arm between the support rod 120 and the first hinge 211 and the second hinge 212, thereby causing the side door 210 to rotate.

[0040] Furthermore, the transmission module 160 also includes a worm (not shown in the figure), which is meshed with the gear 161. The worm is fixedly connected to the driving end of the driving member 140. The driving member 140 can drive the worm to rotate around its axis. The worm drives the gear 161 to rotate, thereby driving the screw 162 to rotate around its axis, and then the side door 210 rotates.

[0041] It is understandable that, in this embodiment, the driving member 140 may be a stepping motor or a servo motor, etc., and this embodiment does not impose any specific limitation on this.

[0042] Furthermore, in this embodiment, the axis of the driving member 140 coincides with the axis of the worm, thereby saving the arrangement space of the driving member 140 .

[0043] In addition, it is worth mentioning that the mounting shell 110 is fixedly connected to the vehicle component by the first bolt 111 and the second bolt 112, the arrangement direction of the first bolt 111 and the second bolt 112 is parallel to the extension direction of the first hinge axis a, and the extension direction of the axis of the driving member 140 is set at an angle to the arrangement direction of the first bolt 111 and the second bolt 112, that is, in this embodiment, compared with the side door 210, the driving member 140 is inclined, and the driving member 140 is inclined toward the side away from the side door 210, so that there is enough safety space between the driving member 140 and the side door 210 to enable the driving member 140 to work safely.

[0044] Optionally, in this embodiment, the angle between the extension direction of the axis of the driving member 140 and the arrangement direction of the first bolt 111 and the second bolt 112 is greater than 0° and less than or equal to 10°. Preferably, the angle between the extension direction of the axis of the driving member 140 and the arrangement direction of the first bolt 111 and the second bolt 112 is greater than or equal to 3° and less than or equal to 6°.

[0045] Based on the above, in the present embodiment, the damper 170 is transmission connected to the gear 161. Specifically, the gear 161 is sleeved on one end of the screw rod 162, and the damper 170 is transmission connected to the end of the gear 161 away from the screw rod 162. Compared with the transmission connection between the damper 170 and the worm gear located upstream of the gear 161, in the present embodiment, there is no transmission ratio between the damper 170 and the screw rod 162, thereby avoiding amplifying the resistance generated by the damper 170 during the transmission process, that is, in the present embodiment, while achieving hovering, the force that the user needs to apply to the side door 210 when manually closing or opening the side door 210 will not be increased, thereby providing great convenience for the user.

[0046] Furthermore, in this embodiment, the moving block 130 is slidably connected to the mounting shell 110 , thereby ensuring that the moving block 130 can accurately move along the extension direction of the screw rod 162 .

[0047] Specifically, a slide rail 113 is provided on the mounting shell 110 . It can be understood that the slide rail 113 extends along the axial direction of the screw rod 162 , and the moving block 130 is slidably connected to the slide rail 113 . The slide rail 113 can provide a guide for the movement of the moving block 130 .

[0048] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
