[0002] The bumper is a device used to absorb collision energy when the vehicle is hit. It consists of a main beam, an energy-absorbing box, and a mounting plate connected to the car. The main beam and the energy-absorbing box can effectively absorb the collision energy when the vehicle collides at a low speed, and minimize the damage of the impact force to the longitudinal beam of the vehicle body, thereby playing its protective role on the vehicle.
[0003] The existing bumper structure is relatively simple, and most of them are made of hollow tubes or plastic parts with low strength. They are easily damaged after a collision. In addition, the existing bumper has poor buffering capacity. When a collision occurs, the attenuation of converting the potential energy of the impact into kinetic energy is limited, making it difficult to effectively protect the vehicle. For this reason, we propose a high-strength bumper. Utility Model Content

[0027] The utility model provides a high-strength bumper, which can effectively improve the strength of the bumper body and the buffering ability of the bumper body to the potential energy generated by the impact. Figure 1-4 , comprising a bumper body 100 and a mounting plate 200;
[0028] Please refer again Figure 1-4 The bumper body 100 is used to install the main structure. A triangular reinforcement strip 110 is fixedly connected between the top and bottom of the inner cavity of the bumper body 100. The triangular reinforcement strip 110 is used to reinforce the bumper body 100, and the triangular reinforcement strips 110 are arranged in sequence from front to back. A reinforcing rib 111 is embedded in the inner cavity of the triangular reinforcement strip 110. The reinforcing rib 111 is used to reinforce the triangular reinforcement strip 110. The inner cavity of the bumper body 100 is filled with a buffer filler 120. The buffer filler 120 is used to reduce the potential energy of the bumper body 100 subjected to the impact. The triangular reinforcement strips 110 are provided to absorb and buffer the impact, and the buffer filler 120 is located between the inner side walls of the adjacent triangular reinforcement strips 110. The triangular reinforcement strips 110 in the bumper body 100 support the bumper body 100, and the overall strength of the bumper body 100 is strengthened. The strength of the triangular reinforcement strips 110 is strengthened by the reinforcing ribs 111, so that the triangular reinforcement strips 110 can further improve the support strength of the bumper body 100, and the buffer filler 120 in the bumper body 100 buffers and absorbs the potential energy of the impact on the bumper body 100.
[0029] In summary, the strength of the bumper body 100 can be effectively improved;
[0030] Please refer again Figure 1-3The mounting plate 200 is located on the right side of the bumper body 100. Specifically, the mounting plate 200 is fixedly connected to the right side of the bumper body 100 through the damping rods 230 on the front and rear sides. The left side wall of the mounting plate 200 is fixedly connected with the damping cylinder 210 on the front and rear sides. The damping cylinder 210 is used to install the main structure. The inner cavity of the damping cylinders 210 on the front and rear sides is embedded with a buffer spring 220. The buffer spring 220 is used to buffer the potential energy generated by the impact. The left ends of the damping cylinders 210 on the front and rear sides are plugged with damping springs. The damping rod 230 is used to install the liquid seepage plate 240. The left ends of the front and rear damping rods 230 are fixedly connected to the bumper body 100. The right ends of the front and rear damping rods 230 penetrate the front and rear damping cylinders 210 and extend to the inner cavities of the front and rear damping cylinders 210. The right ends of the front and rear damping rods 230 are fixedly connected with the liquid seepage plate 240. The liquid seepage plate 240 is used to squeeze the buffer spring 220 and the damping oil 250. The right side wall of the front and rear liquid seepage plate 240 is opened with a liquid seepage plate 240. The liquid holes 241 are evenly distributed, and the inner cavities of the damping cylinders 210 on the front and rear sides are filled with damping oil 250, and the damping oil 250 is located on the right side of the liquid seepage plate 240. When a collision occurs, the bumper body 100 absorbs the potential energy of the collision, and the bumper body 100 squeezes the damping rod 230 so that the damping rod 230 is squeezed into the damping cylinder 210, so that the liquid seepage plate 240 at the end of the damping rod 230 squeezes the buffer spring 220 and the buffer spring 220 in the damping cylinder 210. The impact oil is squeezed, and after squeezing the buffer spring 220, the buffer spring 220 is deformed to absorb the potential energy generated by the impact. At the same time, when the permeable plate 240 squeezes the buffer oil, the buffer oil flows to the other side of the permeable plate 240 through the permeable holes 241 on the permeable plate 240, and in this process, the potential energy generated by the impact is absorbed and offset. Then, the squeezed buffer spring 220 is reset to push the damping rod 230 to reset so that the bumper body 100 is reset;
[0031] In summary, the buffering capability of the bumper body 100 against the potential energy generated by the impact can be effectively improved;
[0032] In specific use, the technical personnel in this field support the bumper body 100 through the triangular reinforcement strip 110 in the bumper body 100, strengthen the overall strength of the bumper body 100, and strengthen the strength of the triangular reinforcement strip 110 through the reinforcing rib 111 so that the triangular reinforcement strip 110 can further improve the support strength of the bumper body 100, and the buffer filler 120 in the bumper body 100 buffers and absorbs the potential energy of the impact on the bumper body 100. When a collision occurs, the bumper body 100 absorbs the potential energy of the impact, and then the bumper body 100 squeezes the damping rod 230 to make the damping rod 230 The damping rod 230 is squeezed into the damping cylinder 210, so that the permeable plate 240 at the end of the damping rod 230 squeezes the buffer spring 220 and the buffer oil in the damping cylinder 210. After squeezing the buffer spring 220, the buffer spring 220 is deformed to absorb the potential energy generated by the impact. At the same time, when the permeable plate 240 squeezes the buffer oil, the buffer oil flows to the other side of the permeable plate 240 through the permeable holes 241 on the permeable plate 240. In this process, the potential energy generated by the impact is absorbed and offset. Then, the squeezed buffer spring 220 is reset to push the damping rod 230 to reset, so that the bumper body 100 is reset.
