Triangle-Profile, three vertex of the triangle being made of reinforcing rib are connect with the middle part of three face inner wall of aluminum supporting block respectively.
The front anticollision beam of automobile of the above-mentioned small offset collision security performance of raising, the supporting block are made of stamping parts soldering
Steel supports block, steel supports block are that cavity is triangular prism shaped, and steel supports block is equipped with crumple muscle.
The front anticollision beam of automobile of the above-mentioned small offset collision security performance of raising, the crumple muscle setting are remote in steel supports block
From on the side wall of energy-absorption box.
The front anticollision beam of automobile of the above-mentioned small offset collision security performance of raising, steel supports block are contacted with energy-absorption box and crossbeam
Face be equipped with flange.
The front anticollision beam of automobile of the above-mentioned small offset collision security performance of raising, supporting block lateral wall and energy-absorption box lateral wall it
Between angle a be 30-60 °.
The present invention cannot give full play to energy-absorbing effect for the strong collision prevention girders of existing automobile energy-absorption box when being subjected to small offset collision
The problem of fruit, is improved, and in the two sides extension supporting block of traditional energy-absorption box, supporting block connects energy-absorption box lateral wall and crossbeam
End.Supporting block is extended to the outside along the direction vehicle body y, front end play improve offset collision during with the contact area of obstacle
Effect；Its rear end is gradually narrowed, and to avoid wheel space, and is conducive to change the direction of transfer of power.Above-mentioned improvement effectively improves
The registration of energy-absorption box and obstacle during small offset collision is conducive to energy-absorption box energy-absorbing and transmits impact force to stringer,
The crumple form of stringer is improved, to reduce the deformation of crew module, improves the safety of occupant in collision process.Structure of the invention
Design is reasonable, easy to implement, simple process, and feasibility is high.
