The invention discloses an automatic tail door device of a truck. The device comprises a carriage bottom plate, a rack, a tail door and action executing mechanisms. The rack is connected to a carriagesupport through a guide rail. Four supporting arms are arranged, the left ends of the four supporting arms are symmetrically hinged to the rack, and the right ends are hinged to a right positioning connecting rod to jointly support the tail door. Two sets of lifting oil cylinders are arranged, two lifting oil cylinders are arranged at each end, the left ends of the lifting oil cylinders are hinged to the upper portion of the rack, and the right ends of pull rods of the lifting oil cylinders are hinged to a second supporting lug of the tail door. The right ends of turnover oil cylinders are hinged to the lower portion of the rack, and the right ends of pull rods of the turnover oil cylinders are hinged to a first supporting lug of the tail door. By means of a lifting executing mechanism, an overturning executing mechanism and a transverse executing mechanism, the three actions of lifting, overturning and transverse moving of the truck tail door are achieved, and unloading and loading can be flexible and stable. The action executing mechanisms adopt the hydraulic cylinders as power sources, so that the rigidity condition is better, and the work is more accurate and stable.

    本发明公开了一种货车自动尾门装置,包括车厢底板、机架、尾门以及动作执行机构,机架通过导轨连接在车厢支架上,支撑臂有四根,四根支撑臂左端对称铰接在机架上,右端与右定位连杆铰接共同支撑尾门,两套升降油缸每端两个,升降油缸左端铰接在机架上方,升降油缸的拉杆右端与尾门的第二支耳铰接,翻转油缸右端铰接在机架下方,翻转油缸的拉杆右端与尾门第一支耳铰接。本发明通过升降执行机构、翻转执行机构和横向执行机构,分别实现货车尾门的升降、翻转和横移三个动作,可实现卸货、上货灵活稳定;本发明的动作执行机构采用液压缸作为动力源,刚性条件更好,工作更加精确稳定。
