The invention discloses an electric folding type tow hook which comprises a fixed seat, a connecting seat relatively rotating on the fixed seat, a tow hook relatively rotating on the connecting seat in a limited mode and a rotation driving unit, and the rotation driving unit is used for driving the connecting seat and the tow hook to conduct unfolding or folding rotation around a preset first axial direction and a preset second axial direction respectively; the towing hook rotates in a rated rotation interval; a compression spring is arranged on a rotating path between the connecting seat and the fixed seat, the compression spring provides assistance for the connecting seat which is unfolded and rotated or provides resistance for the connecting seat which is folded and rotated, and when the tow hook is switched from an unfolded state to a folded state, the tow hook is folded and rotated prior to the connecting seat; on the contrary, when the tow hook is switched from the folded state to the unfolded state, the connecting seat is unfolded and rotated prior to the tow hook.
本发明公开了一种电动折叠式拖车钩,包括固定座、相对旋转于固定座的连座、相对受限旋转于连座的拖钩以及旋转驱动单元,其中,所述旋转驱动单元用于驱使连座和拖钩分别绕预设的第一轴向和第二轴向进行展开或收合旋转;所述拖钩在额定旋转区间内旋转;所述连座与固定座之间的旋转路径上设有压缩弹簧,该压缩弹簧对展开旋转的连座提供助力或对收合旋转的连座提供阻力,其中,当拖车钩由展开状态切换至收合状态时,所述拖钩优先于连座进行收合旋转;反之,当拖车钩由收合状态切换至展开状态时,所述连座优先于拖钩进行展开旋转。
