Shape tabular, and inner side both ends are respectively equipped with the first energy-absorption box；The fire-proof and explosion-proof mechanism includes curved block support base, institute
State with being close on the inside of back buffer beam outside plate on the outside of support base, inner side is provided with two symmetrical second energy-absorption boxes, and both ends bear against two
First energy-absorption box, and matched arc top cover is provided with the top of support base, the support base top surface offers downwards and it
The arc groove that profile is adapted, the arc groove is interior to be provided with matched rubber cushion blocks, the rubber cushion blocks top surface
Offering " V " type groove downwards, the space in the arc groove in addition to rubber cushion blocks is filled with fire prevention liner, and described first
Energy-absorption box and the second energy-absorption box are respectively arranged in mounting bracket；The safety protection mechanism includes two symmetrically arranged safety
Airbag apparatus, the air bag device include impact microphone, control module and the airbag inflated module being sequentially connected,
The impact microphone is arranged in back buffer beam outside plate, and the airbag inflated module is arranged at the top of the first energy-absorption box.
Further, the fire prevention liner is dry powder.
Further, in addition to triangle cushion block.
Further, the triangle cushion block is arranged on mounting bracket side.
Compared with prior art, the beneficial effects of the present invention are：Using fire-proof and explosion-proof mechanism, when receiving shock, branch
Support seat is squeezed and and then so that rubber cushion blocks are squeezed, due to employing " V " type groove at the top of rubber cushion blocks, in rubber
When receiving extruding before and after cushion block, the fire prevention liner of filling can be allowed quickly to spray upwards so that fire prevention liner effectively sprays after shock
It is sprinkled upon on the bonnet for the vehicle that knocks into the back, prevents the generation of fire dangerous situation；Using airbag inflated module, after shock, substitute
Capsule can be ejected quickly, be filled in and knocked into the back between vehicle and the van that is knocked into the back, effectively play cushioning and protection, be protected
Knock into the back the passenger safety of vehicle.

Embodiment
With reference to the accompanying drawings and detailed description, the present invention is furture elucidated, it should be understood that following embodiments are only
For illustrating the present invention rather than limitation the scope of the present invention.
As illustrated, a kind of back buffer beam assembly for van, installed in the tail end bottom of compartment 11 of van
Portion, including back buffer beam outside plate 1, fire-proof and explosion-proof mechanism 2 and safety protection mechanism 3, back buffer beam outside plate 1 are in middle part outwardly convex
Arc tabular 1, and inner side both ends are respectively equipped with the first energy-absorption box 4；Fire-proof and explosion-proof mechanism 2 includes curved block support base
21, the outside of support base 21 is close to the inner side of back buffer beam outside plate 1, and inner side is provided with two symmetrical second energy-absorption boxes 5, and both ends are supported respectively
By two first energy-absorption boxes 4, and the top of support base 21 is provided with matched arc top cover 22, and the top surface of support base 21 opens up downwards
There is the arc groove 23 being adapted with its profile, matched rubber cushion blocks 24, rubber cushion blocks are provided with arc groove 23
