[0002] The front cross member of the vehicle frame is located at the front end of the vehicle frame and is an indispensable component of the vehicle. On the one hand, it can provide mounting points for other components, and on the other hand, it can minimize the damage to people or objects inside and outside the vehicle in the event of a collision.
[0003] In the prior art, the front cross member of the vehicle frame is generally of a two-layer or three-layer structure. Among them, the two-layer structure has problems such as a small cavity, unreasonable layout, and uneven force transmission; the three-layer structure has problems such as excessive weight and insufficient buffering, which is not conducive to maximizing the protection of people or objects inside and outside the vehicle during a collision; at the same time, the rigid connection method is prone to inconvenient replacement after the anti-collision beam is damaged and has a high development cost. With the gradual improvement and upgrading of collision regulations, it can no longer meet the requirements for protecting people and objects inside and outside the vehicle and the general assembly installation method;
[0004] In the process of implementing the present technical solution, the inventor found that the automotive energy absorption box in the prior art has the following defects: the energy absorption effect of the two automotive energy absorption boxes in the prior art is not obvious. During a collision, the absorption capacity of the two energy absorption boxes is limited and cannot ensure the anti-collision effect. Summary of the Utility Model

Both sides of the support plate are fixedly connected to the reinforcing plate through L-shaped plates. The support plate and the L-shaped plates on both sides thereof can transfer the force transmitted by the stress plate to both sides of the reinforcing plate through deformation. The sleeving relationship between the outer plates and the inner plates on both sides can weaken the friction of the transmitted power through the sleeving effect therein. Finally, when reaching the positioning plate, the impact on other structures can be effectively reduced; it can effectively solve the problem that the energy absorption box in the prior art has an unclear effect.

[0010] Furthermore, the stress plate is of a bent structure; through the set stress plate-anti-collision beam body structure, the hollow anti-collision beam structure can unload force through deformation, and the stress plate can, due to its bent structural characteristics, facilitate energy absorption while ensuring its structural strength.
[0011] Furthermore, the anti-collision beam body, the stress plate and the locking leaves are fixedly connected by locking bolts; both sides of the support plate are fixedly connected with the reinforcing plate through the L-shaped plates. The support plate and the L-shaped plates on both sides thereof can transfer the force transmitted by the stress plate to both sides of the reinforcing plate through deformation. The sleeving relationship between the outer side plates and the inner side plates on both sides can weaken the friction of the transmitted power through the sleeving effect therein. Finally, when reaching the positioning plate, the impact on other structures can be effectively reduced.
[0012] Furthermore, gasket structures are fixed at both ends of the reinforcing plate, and hole groove structures are pre-opened in the gaskets. The outer side plate is sleeved on the outer side of the inner side plate, and hole grooves are opened on the outer sides of the outer side plate and the inner side plate.
