It is fixed；
The stiffening plate is fixedly connected on the bottom of main beam housing；
Two energy-absorption boxes are respectively fixedly connected at the bottom both ends of stiffening plate, and the bottom of the energy-absorption box is fixedly connected
There is mounting plate, mounting hole is provided on the mounting plate, crumple guiding groove, the energy-absorbing are provided on the side wall of the energy-absorption box
Box is internally provided with buffer spring, and bottom and the mounting plate of the buffer spring are connected and fixed.
Preferably, the material of the stiffening plate is aluminium alloy.
Preferably, the separator tube is ppr pipe.
Preferably, the bottom of the stiffening plate and main beam housing is welded and fixed, and the top of the energy-absorption box and stiffening plate are welded
Fixation is connect, bottom and the mounting plate of the energy-absorption box are welded and fixed.
Preferably, the bottom of the buffer spring is welded and fixed with mounting plate.
The utility model has the advantages that
(1) a kind of new automobile collision prevention girders of the utility model, main beam housing and its interior separator tube constitute the first order and inhale
Energy buffer area, energy-absorption box and its interior buffer spring constitute second level energy-absorbing buffering area, various structures, absorbable collision energy
More, the utmostly protection to car body may be implemented in when low speed collision.
(2) a kind of new automobile collision prevention girders of the utility model, are provided with stiffening plate, prevent from touching between girder and energy-absorption box
It is smaller and girder is caused to fracture to hit contact area, enables energy-absorption box to play ideal energy-absorbing function, high safety and reliability；Together
When, the crumple guiding groove on energy-absorption box side wall can further improve the energy-absorbing effect of energy-absorption box.
