The invention provides an automatic lifting device for truck unloading. The automatic lifting device comprises a tail plate and lifting mechanisms arranged at the two sides of the tail plate. The tail plate is connected with each lifting mechanism through a fixing shaft, so that the tail plate can rotate around the fixing shaft and can be driven, by the corresponding lifting mechanism, to move up and down; and the tail plate is connected with the fixing shaft through a connecting rod. The lifting process is more stable through a spring and resistance liquid, and compared with a lifting device of a hydraulic system, the cost is greatly reduced. 本发明提供一种货车卸货自动升降装置，包括尾板和设置于所述尾板两侧的升降机构；所述尾板与所述升降机构通过固定轴连接，使所述尾板可以围绕固定轴旋转并在所述升降机构的带动下上下移动；所述尾板通过连杆连接所述固定轴。本发明通过弹簧及阻力液使升降的过程更加平稳，与液压系统的升降装置相比成本大大减小。
