furthermore, a supporting plate is arranged at the front end of the rear anti-collision beam, a limiting lug corresponding to each annular block is arranged on the supporting plate, and the annular blocks are sleeved on the limiting lugs;
further, the width of the supporting plate is smaller than the width of a cavity between the front anti-collision beam and the rear anti-collision beam;
furthermore, a connecting hole is formed in the rear anti-collision beam, and the front anti-collision beam is locked in the connecting hole of the rear anti-collision beam through a bolt;
furthermore, a plurality of bolt holes for mounting the automobile beam are formed in the mounting plate;
further, preceding crashproof roof beam and back crashproof roof beam are arc anticollision roof beam structure.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses simple structure, convenient to use, after bumping, firstly front anticollision roof beam absorbs the energy of collision and produces the deformation of bursting and contracting, secondly the annular piece produces the deformation of bursting and contracting, and it is last rear anticollision roof beam to produce and warp and absorb the collision energy, absorbs and the energy that the buffering collision produced through front anticollision roof beam, annular piece and rear anticollision roof beam, carries out multilayer protection to the car, can play better guard action;
after the anticollision roof beam produces slight deformation before the low-speed collision, can change preceding anticollision roof beam through dismantling, also can carry out solitary change to it after the annular piece takes place deformation, improved the efficiency of work, reduced the cost of maintenance.
