[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] In order to further understand the content of the present invention, the present invention is described in detail with reference to the accompanying drawings.

[0025] Combine Figure 1-Figure 4 The utility model relates to an impact-resistant and deformation-resistant truck bumper assembly, comprising a connecting seat 1 and a lever 2. The lever 2 comprises a pad 21 and a bar frame 22. One end of the connecting seat 1 is connected to the vehicle body by screws, and the other end of the connecting seat 1 is connected to the pad 21 by screws. The bar frame 22 is "C"-shaped, and the pad 21 is engaged in the bar frame 22. The side of the bar frame 22 is locked by screws. A buffer component 23 is provided between the bottom of the connecting seat 1 and the bar frame 22. The buffer component 23 comprises a sleeve 231 and a buckle 232. The buckle 232 is surrounded by steel plates in a diamond-shaped series. A card slot 2311 and a roller 2312 are provided in the sleeve 231. The rollers 2312 are symmetrically arranged on the sides of the buckle 232. When impacted, the diamond-shaped parts of the buckles 232 are driven one by one by the rollers 2312 to squeeze into the card slot 2311 and engage with the card slot 2311 for buffering.

[0026] Combine Figure 4 The roller 2312 is connected to the sleeve 231 through a rotating shaft. The distance between the two rollers 2312 on the side of the buckle 232 is smaller than the widest dimension of the diamond-shaped part of the buckle 232. The diamond-shaped part of the buckle 232 needs to be squeezed into the top of the roller 2312 under force, and a diamond-shaped part of the buckle 232 is engaged between the four rollers 2312.

[0027] Combine Figure 1-Figure 4 The sleeve 231 is connected to the bottom of the connecting seat 1, a sleeve hole 211 is opened on the pad 21, and the buckle 232 is connected to the inner wall of the bar frame 22. The position of the buckle 232 corresponds to that of the sleeve 231. The sleeve 231 passes through the sleeve hole 211 and is engaged with the buckle 232. Several buffer components 23 are evenly distributed.

[0028] The connecting seat 1 includes an "L"-shaped support rod 11, a first diagonal support rod 12, a second diagonal support rod 13 and a base plate 14. The first diagonal support rod 12 and the second diagonal support rod 13 are symmetrically welded on the side of the "L"-shaped support rod 11. The length of the second diagonal support rod 13 is greater than that of the first diagonal support rod 12. The second diagonal support rod 13 is welded outside the first diagonal support rod 12. The "L"-shaped support rod 11, the first diagonal support rod 12 and the second diagonal support rod 13 are welded on the base plate 14.

[0029] The bottom plate 14 is connected to the pad 21 by screws. Several sleeves 231 are evenly distributed and connected to the bottom of the bottom plate 14. The width of the pad 21 is greater than that of the bottom plate 14. The width difference between the pad 21 and the bottom plate 14 matches the folding size of the bar frame 22. The pad 21 is clamped in the bar frame 22.

[0030] Combine Figure 3 and Figure 6 The upper end of the "L"-shaped support rod 11 is in the shape of a gourd string. The gourd string-shaped part at the upper end of the "L"-shaped support rod 11 is provided with a bolt hole. The gourd string-shaped part at the upper end of the "L"-shaped support rod 11 is clamped in the connecting sleeve 3. A gourd string-shaped groove 31 is provided in the connecting sleeve 3. The upper end of the "L"-shaped support rod 11 is locked and connected to the connecting sleeve 3 by bolts, and the connecting sleeve 3 is tightly welded to the vehicle body.

[0031] The gourd string groove 31 is surrounded by steel plates, and the space between the steel plates and the inner wall of the connecting sleeve 3 is filled with rubber. Because the steel plates are not thick and are easy to squeeze, and the rubber has elasticity, it is convenient for the gourd string at the upper end of the "L"-shaped support rod 11 to squeeze upward into the gourd string groove 31 and engage.

[0032] Combine Figure 5 A pulling ring 4 is welded on the "L"-shaped support rod 11, which is used to connect the pulling rod with the vehicle body to pull the connecting seat 1. A pulling head 5 is reserved on the outside of the bar frame 22, and two pulling rings 6 are symmetrically reserved at the bottom outside the bar frame 22 to facilitate towing. A reflective strip is also provided on the outside of the bar frame 22 to protect night driving safety.

[0033] Combine Figure 2 The openings at both ends of the bar frame 22 are connected with cover plates 223, which are connected to the bar frame 22 through hinges. Screw holes are provided on the cover plate 223 for passing screws to lock and connect with the opening edge of the bar frame 22.

[0034] Working principle: When the rear bumper of a large truck is hit by a car, the bar frame 22 drives the buckle 232 to impact forward, and the diamond-shaped part of the buckle 232 collides with the roller 2312. The rotation of the roller 2312 drives the diamond-shaped part of the buckle 232 to engage and buffer one grid at a time. The first diagonal support rod 12 and the second diagonal support rod 13 support the lever 2 diagonally to resist the impact force of the car on both ends of the lever 2. During the collision, the stress of this device is pulled downward. Because the connecting sleeve 3 and the connecting seat 1 are not only connected by bolts, but also by a gourd-like engagement, the possibility of the rear bumper falling off is reduced.

[0035] In summary: The utility model is an impact-resistant and deformation-resistant truck bumper assembly, which buffers impacts by providing a buffer component 23, a first diagonal support rod 12 and a second diagonal support rod 13, so that the lever 2 is not easy to deform and break. By providing a connecting sleeve 3 that is engaged with the connecting seat 1 and connected by bolts, the possibility of the rear bumper being hit and falling off is greatly reduced. This device reduces the impact losses and personal injuries caused by rear-end collisions of large trucks.
