[0020] The present invention will be further described below with reference to the accompanying drawings and implementation examples.
[0021] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 ,in, Figure 1 A schematic structural diagram of a preferred embodiment of the rear anti-collision beam for an automobile provided by the utility model; Figure 2 for Figure 1 A schematic structural diagram of the slider structure shown; Figure 3 for Figure 1 A schematic structural diagram of the limiting plate structure shown; Figure 4 for Figure 2 An enlarged schematic diagram of part A is shown; Figure 5 for Figure 3 The enlarged schematic diagram of part B is shown. The rear anti-collision beam of an automobile comprises: an anti-collision beam 1, with buffer assemblies 3 installed on both the left and right ends of the rear side of the anti-collision beam 1, and a mounting plate 2 installed on the buffer assembly 3. A limiting groove 5 is defined at the top of the anti-collision beam 1, and the limiting groove 5 passes through the front side wall of the anti-collision beam 1. The inner wall of the limiting groove 5 is plugged into a limiting block 6. The front outer wall of the limiting block 6 is installed with a curved plate 7, and the outer wall of the curved plate 7 is installed with a cushioning pad 8. A limiting assembly 9 is installed between the top of the anti-collision beam 1 and the top of the limiting block 6. The anti-collision beam 1 is provided with a slide groove 10 at both the top and bottom left and right ends. The inner wall of each group of the slide grooves 10 is slidably connected with a slider 12. A connecting rod 11 is installed on the top of each group of the sliders 12. The other end of each group of the connecting rod 11 is installed with a side beam 4. A shock-absorbing spring 2 14 is installed between the side wall of each group of the sliders 12 and the inner wall of the slide groove 10. A telescopic rod 2 13 is installed between the side wall of the slider 12 and the inner wall of the slide groove 10. The telescopic rod 2 13 is sleeved inside the shock-absorbing spring 2 14.
[0022] The buffer assembly 3 includes a cylinder 31, which is fixedly connected to the side wall of the mounting plate 2. Cylinders 32 are installed on the left and right rear walls of the anti-collision beam 1. The outer wall of the cylinder 32 is slidably connected to the inner wall of the cylinder 31. A shock-absorbing spring 33 is installed between the end of the cylinder 32 located on the inner wall of the cylinder 31 and the inner wall of the cylinder 31.
[0023] A telescopic rod 34 is installed between the end of the cylinder 32 located on the inner wall of the cylinder 31 and the inner wall of the cylinder 31. The telescopic rod 34 is sleeved inside the shock-absorbing spring 33. When the anti-collision beam 1 is impacted, the impact force will push the anti-collision beam 1 to move backward. The anti-collision beam 1 squeezes the shock-absorbing spring 33 and the telescopic rod 34 through the cylinder 32, thereby effectively offsetting the impact force and reducing the impact force on the anti-collision beam 1.
[0024] A rotating shaft 92 is installed on the top of the anti-collision beam 1 near the entry end of the limit groove 5. The outer wall of the rotating shaft 92 is rotatably connected to the limit plate 91. The bottom of the limit plate 91 is in contact with the top of the limit block 6. A screw 93 is installed between the other end of the limit plate 91 and the top of the anti-collision beam 1. By loosening the screw 93, the limit plate 91 can be rotated to make it leave the entry end of the limit groove 5, thereby facilitating the removal of the limit block 6 from the inside of the limit groove 5.
[0025] The side wall of the mounting plate 2 is evenly provided with a plurality of mounting holes 15 . The arrangement of the mounting holes 15 facilitates fixing the mounting plate 2 to the rear of the vehicle by screws.
[0026] The buffer cotton 8 is made of polyurethane foam, which not only has good buffering performance but also has a light weight and will not cause a large burden on the overall performance of the vehicle.
[0027] The working principle of the rear anti-collision beam of a car provided by the utility model is as follows: when the car is hit from the rear, the buffer cotton 8 will first absorb part of the impact force, and then the anti-collision beam 1 will offset the other part of the force through the buffer component 3. When a collision occurs from the side and rear of the car, the impact force will first squeeze the side beam 4. The side beam 4 is forced to push the slider 12 to move to the other end of the slide groove 10 through the connecting rod 11. At the same time, the shock-absorbing spring 14 is in a compressed state, thereby offsetting part of the impact force, thereby reducing the impact directly caused by the impact force to the anti-collision beam 1.
[0028] Compared with the related art, the automobile rear anti-collision beam provided by the utility model has the following beneficial effects:
[0029] When the car is hit from the rear, the buffer cotton 8 will first absorb part of the impact force, and then the anti-collision beam 1 will offset the other part of the force through the buffer component 3. When the car collides from the side and rear, the impact force will first squeeze the side beam 4. The side beam 4 is forced to push the slider 12 to move to the other end of the slide groove 10 through the connecting rod 11. At the same time, the shock-absorbing spring 2 14 is in a compressed state, thereby offsetting part of the impact force, thereby reducing the impact of the impact force directly on the anti-collision beam 1. The impact force is offset layer by layer in the above manner to ensure the overall impact resistance of the anti-collision beam 1.
