[0045] The embodiment of the present invention provides a bumper device, please refer to Figure 1 and Figure 2The bumper device includes a bumper body 100 and a first buffer device 200. The bumper body 100 is used to be installed on the vehicle body. The first buffer device 200 is connected to the bumper body 100. The first buffer device 200 includes a first buffer member 210. The first buffer member 210 is used to deform and absorb energy. The first buffer member 210 can rotate around the vertical direction and can move along the vertical direction to adjust the relative position of the first buffer member 210 and the bumper body 100.

[0046] The bumper assembly includes a bumper body 100 and a first buffer assembly 200. The bumper body 100 is mounted on the vehicle body. The first buffer assembly 200 includes a first buffer member 210. The first buffer member 210 has deformation and energy absorption properties. When the first buffer member 210 collides with a pedestrian, it deforms and absorbs energy, thereby reducing injuries to the pedestrian. The first buffer member 210 can rotate vertically about the bumper body 100, and the first buffer assembly 200 can drive the first buffer member 210 to move vertically, thereby adjusting the relative position of the first buffer member 210 and the bumper body 100, thereby adjusting the collision position of the first buffer assembly 200 and the pedestrian, thereby reducing injuries to the pedestrian. The bumper device provided in this embodiment adjusts the relative position of the first buffer member 210 and the bumper body 100 when a person collides with a vehicle, thereby adjusting the contact position of the first buffer member 210 and the pedestrian, thereby reducing the risk of injury to the pedestrian in a collision between the person and the vehicle. When a vehicle collides with an object, the relative position of the first buffer member 210 and the bumper body 100 is adjusted, thereby adjusting the collision position of the first buffer member 210 and the colliding object, adjusting the force point of the vehicle, and improving the collision compatibility of the vehicle.

[0047] It should be noted that when a conventional vehicle's sensor system detects a pedestrian in its path while driving, and there is no time to brake and stop the vehicle, adjusting the contact position between the first cushioning member 210 and the pedestrian reduces the risk of injury to the pedestrian in a collision. The collision object may be a vehicle or an external object. During a vehicle-to-vehicle collision, adjusting the contact position between the first cushioning member 210 and the vehicle adjusts the force bearing point of the vehicle, reduces damage to the vehicle, improves collision compatibility, and minimizes occupant injury. During a collision between the vehicle and an external object, adjusting the contact position between the first cushioning member 210 and the external object reduces the risk of damage to the vehicle.

[0048] See also Figure 1 and Figure 2In some embodiments, the bumper body 100 includes a crossbeam 110 for mounting on a vehicle body, and the first buffer device 200 includes a first mounting bracket 220. A first buffer member 210 is slidably mounted on the first mounting bracket 220. The first mounting bracket 220 is rotatably connected to the crossbeam 110. The first mounting bracket 220 can drive the first buffer member 210 to rotate in a vertical direction, and the first buffer member 210 can move in a vertical direction on the first mounting bracket 220. The first buffer member 210 is mounted on the first mounting bracket 220. The first mounting bracket 220 rotates in the vertical direction, thereby driving the first buffer member 210 to rotate in the vertical direction, thereby adjusting the relative position of the first buffer member 210 and the bumper body 100. The first buffer member 210 and the first mounting bracket 220 are slidably engaged, and the first buffer member 210 can slide in the vertical direction on the first mounting bracket 220, thereby adjusting the relative position of the first buffer member 210 and the bumper body 100.

[0049] See also Figures 3 to 5 The first buffer device 200 includes a first drive assembly 230, which includes a rack 231, a gear 232 and a gear drive source 233. The rack 231 is at least partially in contact with the first mounting frame 220, and the rack 231 is arranged along the first direction of the vehicle body, wherein the first direction is parallel to the forward direction of the vehicle body; the gear 232 is engaged with the rack 231; the gear drive source 233 is installed on the crossbeam 110, and the output end of the gear drive source 233 is connected to the gear 232. The gear drive source 233 is used to drive the gear 232 to rotate, so that the rack 231 moving along the first direction of the vehicle body drives the first mounting frame 220 to rotate around the vertical direction. The rack 231 is arranged along the first direction of the vehicle body, and is passed through the crossbeam 110 and partially abuts against the first mounting bracket 220. The gear 232 is engaged with the rack 231. The output end of the gear driving source 233 is connected to the gear 232. The gear driving source 233 drives the gear 232 to rotate, thereby driving the rack 231 to move along the first direction of the vehicle body, and then causing the first mounting bracket 220 to rotate in the vertical direction. The rotation of the first mounting bracket 220 in the vertical direction drives the first buffer member 210 to rotate in the vertical direction, thereby adjusting the relative position of the first buffer device 200 and the crossbeam 110.

[0050] Specifically, the output end of the gear driving source 233 is connected to the first bevel gear, the first bevel gear is meshed with the second bevel gear, the second bevel gear and the gear 232 are coaxially connected, and the gear driving source 233 drives the first bevel gear to rotate and then drives the second bevel gear and the gear 232 to rotate.

[0051] More specifically, see Figures 3 to 5The first drive assembly 230 further includes a gear drive source mounting base 234, which is fixedly connected to the crossbeam 110. The gear drive source 233 is mounted on the gear drive source mounting base 234. In some embodiments, the gear drive source mounting base 234 can be disposed inside the crossbeam 110, thereby allowing the gear drive source 233 to be mounted inside the crossbeam 110 and protecting the gear drive source 233. In some embodiments, the gear drive source mounting base 234 can be connected to the outer wall of the crossbeam 110 to facilitate installation and subsequent maintenance of the gear drive source 233.

[0052] See also Figures 3 to 5 One of the first mounting frame 220 and the rack 231 is provided with a limiting slot 221, and the other is provided with a limiting post 2311. The limiting post 2311 is at least partially located within the limiting slot 221. The limiting post 2311 can abut against the slot wall of the limiting slot 221 to push or pull the first mounting frame 220 to rotate about a vertical direction. The limiting post 2311 is at least partially located within the limiting slot 221. When the rack 231 moves along the first direction of the vehicle body, the limiting post 2311 abuts against the slot wall of the limiting slot 221, and the rack 231 continues to move, providing a pushing or pulling force to the first mounting frame 220, thereby pushing or pulling the first mounting frame 220 to rotate about a vertical direction.

[0053] In some embodiments, a limiting slot 221 is provided on the first mounting frame 220, extending along the length of the first mounting frame 220. A limiting post 2311 is provided on the rack 231. The outer wall of the limiting post 2311 abuts the wall of the limiting slot 221, and the lower end of the limiting post 2311 extends outside the limiting slot 221. In some embodiments, the limiting post 2311 is provided on the first mounting frame 220, and the limiting slot 221 is provided on the rack 231. Both of the above configurations can achieve pushing or pulling the first mounting frame 220 to rotate vertically. The specific configuration is determined based on actual operational needs.

[0055] See also Figures 3 to 5In some embodiments, the first buffer device 200 further includes a locking assembly 240, which includes a connector 241 and a locking drive source 242. The output end of the locking drive source 242 is connected to the connector 241. The locking drive source 242 is used to drive the connector 241 to insert into the rack 231, thereby locking the rack 231 in its current position. By providing the locking assembly 240, the locking drive source 242 drives the connector 241 to insert into the rack 231, restricting the movement of the rack 231 in the forward direction of the vehicle body, thereby locking the rack 231 and fixing the angle between the first mounting bracket 220 and the crossbeam 110.

[0056] Specifically, the plug connector 241 includes a plug-in portion and a connecting portion connected to the plug-in portion. The connecting portion is provided with teeth. A locking gear is fixed to the end of the locking drive source 242. The locking gear meshes with the teeth. The locking drive source 242 drives the locking gear to rotate, causing the connecting portion to drive the plug-in portion to move toward the rack 231, so that the plug-in portion is inserted into some of the teeth of the rack 231, thereby restricting the movement of the rack 231. The locking drive source 242 drives the locking gear to rotate, causing the connecting portion to drive the plug-in portion to move away from the rack 231, thereby unlocking the rack 231.

[0057] Specifically, in some embodiments, the bumper body 100 includes a vertical beam 120, and the locking drive source 242 is mounted on the vertical beam 120 via a locking drive source mounting seat 243. In some embodiments, the locking drive source mounting seat 243 may not be provided, as long as the locking drive source 242 can be mounted.

[0058] See also Figure 1 and Figure 2 In some embodiments, the first buffer device 200 further includes a first support frame 270, which is slidably connected to the first mounting frame 220. The first support frame 270 and the first mounting frame 220 are at least partially disposed within the first buffer member 210. The first mounting frame 220 drives the first support frame 270 to move in the vertical direction, so that the first support frame 270 drives the first buffer member 210 to move in the vertical direction. The first support frame 270 is provided to mount the first buffer member 210, and the sliding connection between the first support frame 270 and the first mounting frame 220 is achieved to achieve a sliding connection between the first buffer member 210 and the first mounting frame 220.

The drive shaft 251 is arranged along the width direction of the vehicle body. A first tooth is provided on the drive shaft 251. The first support frame 270 is provided with a second tooth meshing with the first tooth. The second tooth is arranged in the vertical direction. The drive shaft driving source 252 is used to drive the drive shaft 251 to rotate, thereby causing the first support frame 270 to move up and down in the vertical direction.

[0060] Specifically, a first driving gear is sleeved on the driving shaft driving source 252, and a second driving gear is sleeved on the driving shaft 251. The first driving gear is engaged with the second driving gear, so that the driving shaft driving source 252 drives the second driving gear and the driving shaft 251 to rotate through the first driving gear.

[0061] In some embodiments, a slide rail is provided on one of the first support frame 270 and the first mounting frame 220 , and a slider is provided on the other.
