The third limiting wall 1211 can be aligned with the first limiting wall 2221. The limiting wall 2221 is guided and matched, and the guiding notch groove 1212 is guided and matched with the clamping structure 221, so that the clamping structure 221 can move along the assembly direction of the cover plate 20, and at the same time, the clamping structure 221 pushes the clamping block 121 to move along the radial direction of the trailer hook assembly hole 11 toward the inner wall close to the trailer hook assembly hole 11, so that the cover plate 20 moves along the assembly direction of the cover plate 20, which is conducive to the disassembly and installation of the cover plate 20 and the bumper body 10. The side wall of the guiding notch groove 1212 can limit the clamping structure 221, reduce the probability of the clamping structure 221 being offset when the clamping structure 221 is guided and matched with the guiding notch groove 1212, improve the stability of the movement of the clamping structure 221, and improve the stability of the cover plate 20 when disassembling and assembling.

[0057] The third limiting wall 1211 is guided and cooperated with the first limiting wall 2221. The third limiting wall 1211 and the first limiting wall 2221 are both constructed as inclined walls. The angle formed by the third limiting wall 1211 and the horizontal plane is recorded as the first angle, and the angle formed by the first limiting wall 2221 and the horizontal plane is recorded as the second angle. The first angle and the second angle are complementary angles. Exemplarily, the first angle can be 105°, 110°, 112°, 115°, etc. The angle value of the first angle can be in the range of 105° to 115°. Any value, including the endpoint value, is an optional angle value of the first angle of the utility model. If the angle value of the first angle is less than 105°, the clamping structure 221 is affected to move along the assembly direction of the cover plate 20, thereby affecting the movement of the cover plate 20 along the assembly direction of the cover plate 20; if the angle value of the first angle is greater than 115°, the clamping block 121 is affected to move along the radial direction of the trailer hook assembly hole 11, affecting the locking and unlocking of the first limiting portion 12 and the second limiting portion 22. Therefore, the angle formed by the third limiting wall 1211 and the horizontal plane is between 105° and 115°, so that the clamping block 121 can move along the radial direction of the trailer hook assembly hole 11, so that the clamping structure 221 can move along the assembly direction of the cover plate 20, thereby causing the cover plate 20 to move along the assembly direction of the cover plate 20, which is conducive to the disassembly and installation of the cover plate 20 and the bumper body 10.

[0058] In some embodiments of the present invention, Figure 1 and Figure 3As shown, the limiting wall 21 is fixed on the inner surface of the cover plate 20 facing the bumper body 10, and the limiting wall 21 includes a connecting wall portion 211 and a limiting wall portion 212. The connecting wall portion 211 is connected between the limiting wall portion 212 and the cover plate 20 to form a clamping space 213 between the limiting wall portion 212 and the cover plate 20. When the cover plate 20 covers the trailer hook assembly hole 11, part of the bumper body 10 is assembled in the clamping space 213.

[0059] The limiting wall 21 is fixedly arranged on the inner surface of the cover plate 20 facing the bumper body 10, the limiting wall 21 is penetrated through the trailer hook assembly hole 11 and abuts against the inner wall of the bumper body 10 for limiting, the limiting wall 21 includes a connecting wall portion 211 and a limiting wall portion 212, the connecting wall portion 211 is connected between the limiting wall portion 212 and the cover plate 20, the connecting wall portion 211 can be integrally formed with the limiting wall portion 212 and the cover plate 20, and the connecting wall portion 211 can be integrally formed with the limiting wall portion 212 and the cover plate 20. The plate 20 is welded and connected, and a clamping space 213 is formed between the limiting wall portion 212 and the cover plate 20. When the cover plate 20 covers the trailer hook assembly hole 11, part of the bumper body 10 is assembled in the clamping space 213, and the limiting wall portion 212 abuts against the bumper body 10, and the cover plate 20 abuts against the bumper body 10, so that the limiting wall 21 can limit the cover plate 20, so that the connection between the cover plate 20 and the bumper body 10 is tighter, thereby improving the safety of the bumper assembly 1.

[0060] An angle is formed between the limiting wall portion 212 and the connecting wall portion 211. For example, the angle between the limiting wall portion 212 and the connecting wall portion 211 can be 105°, 110°, 112°, 115°, etc. The angle between the limiting wall portion 212 and the connecting wall portion 211 can be in the range of 105° to 115°. Any value including the endpoint value is an optional angle between the limiting wall portion 212 and the connecting wall portion 211 of the utility model. The angle between the limiting wall portion 212 and the connecting wall portion 211 is between 105° and 115°, so that the limiting wall 21 can improve the tightness of the connection between the cover plate 20 and the bumper body 10, and the cover plate 20 can be more easily removed from the bumper body 10, so that the operation is simple and the operation efficiency is improved. If the angle between the limiting wall portion 212 and the connecting wall portion 211 is less than 105°, it will affect the removal of the cover plate 20 from the bumper body 10 ; if the angle between the limiting wall portion 212 and the connecting wall portion 211 is greater than 115°, it will affect the limiting effect of the limiting wall 21 on the cover plate 20 .

[0061] In some embodiments of the present invention, Figure 1 As shown, the limiting wall 21 and the second limiting portion 22 are both disposed on the inner surface of the cover plate 20 facing the bumper body 10 , and the limiting wall 21 and the second limiting portion 22 are disposed opposite to and spaced apart from each other.

[0062] The limiting wall 21 and the second limiting portion 22 are both arranged on the inner surface of the cover plate 20 facing the bumper body 10. The limiting wall 21 limits the cover plate 20. The second limiting portion 22 is locked or unlocked with the first limiting portion 12 to realize the disassembly and assembly of the cover plate 20 and the bumper body 10. The limiting wall 21 and the second limiting portion 22 are arranged opposite to each other and spaced apart, so that the limiting wall 21 and the second limiting portion 22 can jointly realize the limiting and fixing effect on the cover plate 20.

[0063] In the embodiment of the present application, when the cover plate 20 is removed from the bumper body 10, the cover plate 20 is pressed inward along the assembly direction of the cover plate 20, the snap-in structure 221 moves inward, and the snap-in block 121 cooperates with the guide of the snap-in structure 221. While the snap-in structure 221 moves, the snap-in structure 221 pushes the snap-in block 121 to move toward the inner wall of the trailer hook assembly hole 11. When the snap-in block 121 moves out of the slot 222, the first limiting portion 12 and the second limiting portion 22 are unlocked. At this time, the limiting cooperation between the limiting wall 21 and the bumper body 10 can be easily released from the outside, and the cover plate 20 is removed to expose the trailer hook assembly hole 11, so that the trailer hook can be assembled with the vehicle to realize the trailer operation. When the cover plate 20 covers the trailer hook assembly hole 11, the limiting wall 21 is first assembled with the bumper body 10 to limit and match, and the cover plate 20 is pushed inward. The clamping structure 221 moves inward and pushes the clamping block 121 toward the inner wall of the trailer hook assembly hole 11. When the clamping block 121 corresponds to the clamping groove 222, the clamping structure 221 no longer pushes the clamping block 121 to move, and the elastic driving member 122 drives the clamping block 121 to move along the radial direction of the trailer hook assembly hole 11. The clamping block 121 moves toward the direction close to the clamping structure 221, and the clamping block 121 is clamped into the clamping groove 222. The clamping block 121 and the clamping groove 222 are limited and matched, the second limiting portion 22 is clamped with the first limiting portion 12, and the second limiting portion 22 is locked with the first limiting portion 12, so that the cover plate 20 is fixed on the bumper body 10, and the cover plate 20 covers the trailer hook assembly hole 11.
