The invention provides a trailer traction device which comprises a mounting frame, a driving motor, a transmission part and a trailer hook, wherein the driving motor and the transmission part are arranged on the mounting frame; the trailer hook is connected with the driving motor through the transmission part; the transmission part is provided with a deflector rod connected with the driving motor, a main shaft arranged in a rotating mode and a locking mechanism used for locking rotation of the main shaft, the tow hook is connected to the main shaft, and the deflector rod is provided with an unlocking end and a transmission end; under the driving of the driving motor, the driving lever rotates and can sequentially enter an unlocking stroke and a transmission stroke, in the unlocking stroke, the unlocking end can apply unlocking force in the axial direction of the main shaft to the locking mechanism so that the locking mechanism can be unlocked, and in the transmission stroke, the transmission end can drive the main shaft to rotate so that the tow hook can be unfolded to a working position or stored to one side of the mounting frame. According to the trailer traction device, automatic unfolding and folding of the trailer hook can be achieved, the trouble of manually breaking off the trailer hook can be omitted, injuries such as hand clamping and collision can be avoided, and the use convenience of the trailer hook can be improved.

    本发明提供了一种拖车牵引装置,包括安装架,以及设于安装架上的驱动电机、传动部和通过传动部与驱动电机连接的拖车钩;传动部具有与驱动电机连接的拨杆,转动设置的主轴,以及用于对主轴的转动进行锁止的锁止机构,且拖车钩连接在主轴上,拨杆上设有解锁端与传动端;在驱动电机的驱使下,拨杆转动能够依次进入解锁行程和传动行程,在解锁行程,解锁端能够对锁止机构施加沿主轴轴向的解锁力,以使锁止机构解锁,在传动行程,传动端能够带动主轴转动,以使拖车钩展开至工作位,或收纳至安装架的一侧。本发明的拖车牵引装置能够实现拖车钩的自动展开及收纳,可省去手动掰拖车钩的麻烦,能够避免夹手、磕碰等伤害,有助于提升拖车钩使用的便捷性。
