The invention discloses a trailer coupler, belongs to the technical field of automobiles, solves the problem that an existing trailer coupler is too complex in structure, and comprises a mounting frame, a towing hook, a driving component, a first actuating piece and a second actuating piece, a sleeve is arranged on the mounting frame, the towing hook is arranged on the outer side of the sleeve in a sleeving mode, and the driving component is arranged on the mounting frame. The first actuating piece is arranged in the sleeve and is driven by the driving component to rotate, a rotation stopping piece is arranged between the first actuating piece and the towing hook, the rotation stopping piece generates radial motion on the sleeve through the rotation motion of the first actuating piece so as to lock or unlock the towing hook, and one of the second actuating piece and the towing hook is provided with a transmission protrusion. And the other one is provided with a spiral guide section and a transmission part, the unlocking process of the towing hook is accompanied by the axial displacement and rotation of the second actuating piece, the transmission bulge moves towards the transmission part along the spiral guide part, and the transmission part acts on the transmission bulge to drive the towing hook to rotate after the towing hook is unlocked.

    本发明公开了拖车联接器,属于汽车技术领域,解决了现有拖车联接器结构过于复杂的问题,本发明的拖车联接器,包括安装架、拖钩、驱动部件、第一致动件和第二致动件,安装架上设有套筒,拖钩套装于套筒外侧,第一致动件设于套筒内并由驱动部件驱动旋转,第一致动件和拖钩之间设有止转件,第一致动件的旋转运动使止转件在套筒上产生径向运动用于锁定或者解锁拖钩,第二致动件和拖钩其中一个设有传动凸起,另一个设有螺旋引导段和传动部,拖钩的解锁过程伴随着第二致动件的轴向位移和旋转,并使传动凸起沿着螺旋引导部向传动部移动,传动部在拖钩完成解锁后作用于传动凸起而带动拖钩旋转。
