The invention discloses a trailer coupler which comprises a mounting seat, a trailer hook, a driving shaft and a driven shaft, the driven shaft is rotatably mounted on the mounting seat and drives the trailer hook to rotate so that the trailer hook can be switched between a folded position and an unfolded position, the driving shaft is a cam shaft, and the trailer coupler further comprises a self-locking sliding block capable of sliding in the radial direction of the cam shaft. The mounting seat is provided with a lock pin capable of axially moving along the driven shaft, the tow hook is provided with a lock groove, and when the tow hook is located at the folding position or the unfolding position, the self-locking sliding block stops the lock pin so that the lock pin can be matched with the lock groove to lock the tow hook, and the cam shaft has an idle stroke for idling and a working stroke for driving the driven shaft to rotate. When the cam shaft is in an idle stroke, the cam shaft drives the self-locking sliding block to move so that the self-locking sliding block can relieve stopping of the lock pin, and when the cam shaft is in a working stroke, the driven shaft can drive the trailer hook to rotate so as to drive the lock pin to move and break away from the lock groove.
本发明公开了一种拖车联接器,包括安装座、拖车钩、主动轴和从动轴,从动轴转动安装在安装座上并带动拖车钩转动以使其在收拢位置和展开位置之间切换,主动轴为凸轮轴,拖车联接器还包括能沿着凸轮轴径向滑动的自锁滑块,安装座设有能沿着从动轴轴向移动的锁销,拖车钩具有锁槽,拖车钩处于收拢位置或展开位置时,自锁滑块止挡锁销,以使锁销与锁槽配合锁定所述拖车钩,凸轮轴具有空转的空行程和驱动从动轴转动的工作行程,凸轮轴处于空行程时驱动自锁滑块移动以使自锁滑块解除对锁销的止挡,以在凸轮轴处于工作行程时能通过从动轴带动拖车钩转动驱使锁销移动并脱离锁槽。
