Automobile threshold anti-collision box assembly

Abstract

The invention discloses an automobile threshold anti-collision box assembly. The automobile threshold anti-collision box assembly comprises a threshold anti-collision box bracket and a threshold anti-collision box supporting plate, wherein the threshold anti-collision box bracket is composed of a main plate and two side plates to form an n shape, each side plate is provided with a collapse hole, and the threshold anti-collision box supporting plate is connected to the portion between the two side plates and is not connected with the main plate. The automobile threshold anti-collision box assembly has the advantages that the transverse width of a supporting surface of the n-shaped threshold anti-collision box bracket is large, it is ensured that the threshold anti-collision box bracket is provided with larger deformation space when the side collision occurs, the energy absorption is facilitated when the side collision occurs, the collapse holes respectively formed in the side plates appropriately reduce the strength of the threshold anti-collision box bracket, are helpful for the rapid collapse and deformation of the threshold anti-collision box bracket in case of collision and areconductive to the absorption of energy; the threshold anti-collision box supporting plate can also increase the structural rigidity of the threshold anti-collision box bracket, effectively reduce theamount of intrusion during side collision, ensure the crashworthiness of a personnel compartment of an automobile, ensure the safety of the personnel in the automobile, and effectively reduce the injury of the personnel in the automobile.

Description

technical field [0001] The invention relates to the technical field of automobile anti-collision protection, in particular to an automobile threshold anti-collision box assembly. Background technique [0002] At present, the side collision of the door sill beam of the automobile body is the key protection place during the collision of the whole vehicle. Now the anti-collision structure is mainly welded on both sides of the door sill beam of the car body. The traditional anti-collision box adopts the upper and lower plate structure, but this anti-collision The overall structure of the box is long. When a collision occurs, the anti-collision box is easy to be crushed and fails to effectively control the crushing direction, and is prone to uneven force. When a collision occurs, the energy absorption effect is poor. The effect of reducing the impact force is relatively weak, which will easily cause the problem of insufficient safety protection for the personnel compartment of th...
