The utility model provides a rear anti collision beam assembly for a van, including a rear panel, a fireproof and explosion-proof mechanism and a safety protection mechanism. A first suction box is provided on both sides of the inner side of the outer plate of the rear anti collision beam. The fireproof and explosion-proof mechanism includes a support seat, a second energy absorption box is provided on the inner side of the support seat, and an arc at the top is provided. The top surface of the support seat is provided with an arc groove, a rubber pad is arranged in the arc groove, the top surface of the rubber pad is provided with a \V\ groove, and a fireproof inner lining is filled in the arc grooves. The safety protection mechanism includes the airbag device, and the air bag device comprises a collision sensor, a control module and a safety air bag filling in turn. Gas module. The advantages are: the fireproof and explosion-proof mechanism is used, the fireproof lining is sprayed on the hood of the rear end vehicle after the impact, preventing the occurrence of the fire danger, and the airbag inflatable module is adopted. After the impact, the airbag can be filled between the rear end vehicle and the rear end van, which effectively plays the role of buffer and protection.

一种用于厢式货车的后防撞梁总成
本专利技术涉及汽车
,尤其涉及一种用于厢式货车的后防撞梁总成。
技术介绍
防撞钢梁是用冷轧钢板冲压而成的U形槽,与车架纵梁连接,作为汽车被动安全的第一道屏障,防撞钢梁是吸收和缓和外界冲击力、防护车身前后部的重要安全机构。目前,现有的厢式货车的后防撞梁仅仅为几根防撞杆,若发生较为重大的小轿车追尾事故,由于小轿车的高度明显要低于厢式货车,小轿车的车头会直接冲击进入到厢式货车的车厢尾端底部,而厢式货车的车厢尾端会直接冲击追尾小轿车的顶部,造成小轿车被“削顶”或完全变形,严重危害小轿车内的驾驶员和乘客安全,此外,由于车头变形,极易造成漏油和爆炸事故,安全隐患极大。
技术实现思路
为解决上述问题,本专利技术公开了一种用于厢式货车的后防撞梁总成。为了达到以上目的,本专利技术提供如下技术方案:一种用于厢式货车的后防撞梁总成,安装在厢式货车的车厢尾端底部,其特征在于:包括后防撞梁外板、防火防爆机构和安全保护机构,所述后防撞梁外板呈中部向外凸起的弧形板状,且内侧两端分别设有第一吸能盒;所述防火防爆机构包括呈弧形块状的支撑座,所述支撑座外侧与后防撞梁 ...
