The tail bumper of the freight vehicle comprises an anti-collision turning plate, a first-stage anti-collision buffering mechanism and a second-stage anti-collision buffering mechanism, the anti-collision turning plate is installed at the tail of the freight vehicle in an overturning mode, and the first-stage anti-collision buffering mechanism and the second-stage anti-collision buffering mechanism are both installed on the rear side of the anti-collision turning plate and are blocked on the motion track line of the anti-collision turning plate. The two-stage anti-collision buffering mechanism is designed, the first-stage anti-collision buffering mechanism aims at low-speed rear-end collision accidents, the second-stage anti-collision buffering mechanism takes effect in a linkage mode in the high-speed rear-end collision accidents, the double buffering effect is achieved through the first-stage anti-collision buffering mechanism and the second-stage anti-collision buffering mechanism, and therefore the anti-collision effect is achieved. The anti-collision buffering mechanism has the advantage of being good in buffering effect, collision kinetic energy can be fully absorbed and released, the safety of personnel in a rear-end collision trolley can be protected during a collision accident, and damage to the rear-end collision trolley can be reduced to the maximum extent.
本发明公开一种货运车辆的尾部防撞器,包括防撞翻板、一级防撞缓冲机构和二级防撞缓冲机构,防撞翻板翻转安装在货运车辆的尾部,一级防撞缓冲机构和二级防撞缓冲机构都安装在防撞翻板后侧,并阻挡于防撞翻板的运动轨迹线上,一级防撞缓冲机构套装在二级防撞缓冲机构外侧,本发明设计有两级防撞缓冲机构,一级防撞缓冲机构针对低速的追尾撞击事故,二级防撞缓冲机构在高速的追尾撞击事故中联动起效,与一级防撞缓冲机构形成双重缓冲效果,本发明的防撞缓冲机构具有缓冲效果好的优点,能充分吸收和释放撞击动能,撞击事故时既能保护追尾小车内的人员安全,又能最大可能的降低对追尾小车的损伤。
