The invention discloses a vehicle bottom hanging type collision protection device. The device comprises connecting buffer structures installed on longitudinal beams on the two sides of a vehicle and asquare steel frame installed between the connecting buffer structures on the two sides. Compared with a traditional linear steel frame, the square steel frame can deform to absorb energy, and the energy absorption capacity is higher; the height of the square steel frame is lower than that of the longitudinal beam; by means of the structure, when the square steel frame moves backwards, movement interference between the square steel frame and the total square steel frame is avoided; an energy-absorbing water tank is detachably arranged above the square steel frame, and a partition plate is arranged in the energy-absorbing water tank and is formed by welding double layers of steel plates; higher anti-pressure capability is realized; the device can be installed at the tail of a frame of the trailer, the distance is prolonged, energy is absorbed when the head of the trailer is inserted, and collision damage to the trailer is reduced.

    本发明公开了一种车辆底挂式碰撞保护装置,包括安装于车辆两侧纵梁上的连接缓冲结构,以及安装在两侧所述连接缓冲结构之间的方形钢架;相较于传统的“一”字形钢架,方形钢架可形变吸能,吸能能力更强;所述方形钢架的高度低于纵梁的高度;该结构,使得方形钢架在向后移动的时候,避免与总量在回见发生移动干涉;所述方形钢架的上方可拆卸的设置有吸能水箱,所述吸能水箱的内部设置有隔板,隔板采用双层钢板焊接;具有更强的抗压能力;本装置可以安装在拖车的车架尾部,延长距离,让车头扎入的时候就进行吸能,减少碰撞车损。
