The invention provides an automobile body chassis buffer device, which relates to the technical field of automobile safe driving and comprises a lower chassis, the lower chassis and an upper automobile body are fixedly connected through a plurality of connecting points, the connecting points fail to be broken or separated after being impacted, and the upper automobile body and the lower chassis are provided with mutually matched buffer devices. The buffer device is used for buffering the upper vehicle body after the lower chassis is separated from the upper vehicle body, and a guide rail is arranged on the buffer device; the guide rails are used for limiting the moving range of the upper vehicle body on the lower chassis, the lower chassis is separated from the upper vehicle body after the vehicle is collided, and various buffering means are passively triggered along with displacement of the upper vehicle body relative to the lower chassis. The technical problems that an existing vehicle body chassis buffering device needs to be initiatively started after a vehicle or a driver judges that collision cannot be avoided, the buffering means cannot play a role in time when sudden collision occurs, and passengers are severely injured are solved.

    本发明提供了一种车身底盘缓冲装置,涉及汽车安全驾驶技术领域,包括下底盘,下底盘和上车身通过若干连接点固定连接,连接点受到冲击后失效断裂或分离,上车身和下底盘上设置有相互配合的缓冲装置,缓冲装置用于下底盘与上车身分离后对上车身进行缓冲,缓冲装置上设置有导轨;导轨用于限制上车身在下底盘上的移动范围,车辆遭遇碰撞后下底盘与上车身分离,随着上车身相对于下底盘产生位移被动性的触发多种缓冲手段,解决了现有的车身底盘缓冲装置缓冲手段需要车辆或驾驶员判断无法避免碰撞后需要主动性启动,遭遇突发性碰撞时会导致缓冲手段不能及时发挥作用,导致乘员受到较大的伤害的技术问题。
