Technical Field

[0001] The utility model relates to the technical field of automobile components, in particular to a vehicle body collision energy absorption structure of an automobile. Background Technique

[0002] The vehicle body collision energy absorption structure of an automobile is a structure designed to absorb and disperse collision energy. For example, the energy absorption box on an automobile is a device specifically designed to absorb and disperse impact energy. By effectively controlling and reducing the impact force, damage to equipment and structures can be reduced.

[0003] Currently, when the existing energy absorption box on an automobile is in use, the impact force borne by the energy absorption box is limited. After the energy absorption box is broken, it can no longer play a role in reducing the impact, which causes the subsequent impact force to directly impact the vehicle body and the driver inside the vehicle. Summary of the Utility Model

A first heat-resistant rubber pad is connected to the side of the first connecting plate away from the first inner energy absorption box. A second connecting plate is connected to the side of the first heat-resistant rubber pad away from the first connecting plate. A second inner energy absorption box is welded on the side of the second connecting plate away from the main anti-collision beam. A third connecting plate is welded on the side of the second inner energy absorption box away from the second connecting plate.

[0007] Preferably, a second heat-resistant rubber pad is connected to the side of the third connecting plate away from the main anti-collision beam. A fourth connecting plate is connected to the side of the second heat-resistant rubber pad away from the main anti-collision beam. A third inner energy absorption box is welded on the side of the fourth connecting plate away from the main anti-collision beam. The side of the third inner energy absorption box away from the main anti-collision beam is welded to the flange. Outer collapse holes are formed on the outer energy absorption box.

[0008] Preferably, first collapse holes are formed on the first inner energy absorption box. Protrusions and grooves are distributed on the first inner energy absorption box. The first collapse holes are distributed on the grooves.

[0009] Preferably, the first connecting plate and the second connecting plate, and the third connecting plate and the fourth connecting plate are sleeved with a limiting rod, and both ends of the limiting rod limit the first connecting plate and the second connecting plate, and the third connecting plate and the fourth connecting plate.

[0010] Preferably, the second inner energy absorption box is in the shape of a quadrangular prism, and second collapse holes are formed on the edges of the second inner energy absorption box, and a metal half-ring belt is welded inside the second inner energy absorption box.

[0011] Preferably, the third inner energy absorption box is in the shape of a hexagonal prism, and third collapse holes are formed on the surfaces of the hexagonal prism on the outer surface of the third inner energy absorption box.

[0013] 1.

At the same time, after the first inner energy absorption box, the second inner energy absorption box and the third inner energy absorption box are broken, they can also be used as cushioning materials to squeeze the first heat-resistant rubber pad, and cooperate with the first heat-resistant rubber pad to play a certain buffering effect, so as to further improve the safety of the device during use and provide better protection.

[0014] 2. For the body collision energy absorption structure of the automobile, by providing the first inner energy absorption box and the third inner energy absorption box, through the first inner energy absorption box, the second inner energy absorption box and the third inner energy absorption box, and the first collapse holes, second collapse holes and third collapse holes formed on the first inner energy absorption box, the second inner energy absorption box and the third inner energy absorption box, the energy absorption of the first inner energy absorption box, the second inner energy absorption box and the third inner energy absorption box is increased in turn, so that the first inner energy absorption box, the second inner energy absorption box and the third inner energy absorption box will play a role within a specific impact energy range, thereby optimizing the impact energy absorption process and making the distribution of the overall impact force more uniform.

[0023] Refer to Figures 1-5, A vehicle body collision energy absorption structure, including a main anti-collision beam 1. On one side of the main anti-collision beam 1 near the front and back positions, an outer energy absorption box 2 is welded. On the side of the outer energy absorption box 2 away from the main anti-collision beam 1, a flange plate 3 is welded. Near the main anti-collision beam 1 on the inner side of the outer energy absorption box 2, a first inner energy absorption box 5 is provided. On the side of the first inner energy absorption box 5 away from the main anti-collision beam 1, a first connecting plate 6 is welded. Between the first connecting plate 6 and the second connecting plate 9, and between the third connecting plate 11 and the fourth connecting plate 13, a limiting rod 7 is sleeved, and both ends of the limiting rod 7 limit the first connecting plate 6 and the second connecting plate 9, and the third connecting plate 11 and the fourth connecting plate 13. On the side of the first connecting plate 6 away from the first inner energy absorption box 5, a first heat-resistant rubber pad 8 is connected. On the side of the first heat-resistant rubber pad 8 away from the first connecting plate 6, a second connecting plate 9 is connected. On the side of the second connecting plate 9 away from the main anti-collision beam 1, a second inner energy absorption box 10 is welded. The second inner energy absorption box 10 is in the shape of a quadrangular prism, and second collapse holes 18 are opened on the edges of the second inner energy absorption box 10. Inside the second inner energy absorption box 10, a metal half-ring belt 19 is welded. On the side of the second inner energy absorption box 10 away from the second connecting plate 9, a third connecting plate 11 is welded.

[0024] Refer to Figures 1-5 , On the side of the third connecting plate 11 away from the main anti-collision beam 1, a second heat-resistant rubber pad 12 is connected. The provision of the first heat-resistant rubber pad 8 and the second heat-resistant rubber pad 12 can play a certain buffering effect after three strong impacts on the overall device and after the internal structure of the device collapses. On the side of the second heat-resistant rubber pad 12 away from the main anti-collision beam 1, a fourth connecting plate 13 is connected. On the side of the fourth connecting plate 13 away from the main anti-collision beam 1, a third inner energy absorption box 14 is welded. The provision of the first inner energy absorption box 5, the second inner energy absorption box 10, and the third inner energy absorption box 14 can effectively increase the impact force bearing range and improve the overall energy absorption effect of the device.

Protrusions 16 and grooves 17 are distributed on the first inner energy absorption box 5. The first collapse holes 15 are distributed on the grooves 17.

[0025] In the present utility model, when a collision occurs again, first, the outer energy absorption box 2 will deform to achieve energy absorption. After the outer energy absorption box 2 collapses, the first inner energy absorption box 5, the second inner energy absorption box 10, and the third inner energy absorption box 14 will bear the impact force. Through the openings of the first collapse hole 15, the second collapse hole 18, and the third collapse hole 20, the first inner energy absorption box 5, the second inner energy absorption box 10, and the third inner energy absorption box 14 can relieve the impact force through deformation after energy absorption. And due to the different positions of the second collapse hole 18 and the third collapse hole 20 and the provision of the convex block 16 and the groove 17, the energy absorption of the first inner energy absorption box 5, the second inner energy absorption box 10, and the third inner energy absorption box 14 increases in sequence, so as to make the distribution of the overall impact force more uniform.
