Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
The utility model provides a buffering shock-absorbing type car bumper as shown in the figure, which comprises an outer plate 1, a buffering material 2 and a cross beam 3, wherein the cross beam 3 is a U-shaped structure formed by stamping a cold-rolled sheet with the thickness of 1-2 mm, the cross beam 3 is arranged on one side of a frame 4, the middle part of the inner surface of the cross beam 3 is fixedly connected with a first fixed block 5, the middle part of the outer surface of the frame 4 is fixedly connected with a second fixed block 6, the buffering material 2 is arranged between the cross beam 3 and the frame 4, the buffering material 2 comprises a main buffering spring 201, a damping buffer 202, a rubber rod 203 and an auxiliary buffering spring 204, two ends of the main buffering spring 201 are respectively welded and fixed with the first fixed block 5 and the second fixed block 6, the damping buffer 202 is arranged on two sides of the main buffering spring 201, the rubber rod 203 is arranged on two sides of the damping buffer 202, the auxiliary buffer spring 204 is arranged between the cross beam 3 and the rubber rod 203, and a buffer filling belt 301 is further arranged inside the cross beam 3. In addition, the outer plate 1 is arranged on the outer surface of the cross beam 3, and the adopted material is polycarbonate plastic, so that the outer plate not only has high-strength rigidity, but also has the advantage of being welded, and has good coating performance. The first fixing block 5, the second fixing block 6 and the main buffer spring 201 are all provided one and are located on the same central axis, so that the main buffer spring 201 can play a buffering role more effectively.
