Document Type and Number:
WIPO Patent Application WO/2023/038422
Kind Code:
A1
Abstract:
The present invention relates to a bistable device, and a vertical- and horizontal-self-alignment docking system using same, and, more specifically, to a bistable device, and a vertical- and horizontal-self-alignment docking system using same, the device enabling a trailer and a transport vehicle to be self-aligned in the vertical and horizontal directions without the aid of external equipment and be conveniently docked. The present invention provides the bistable device which comprises: a driving motor; a gear connected to the driving motor; a cam rod having one end coupled to one surface of the gear so as to reciprocate according to the rotation of the gear; a lock key coupled to the outer end of the cam rod so as to move linearly; and a spring having one end fixed to a housing and having the other end fixed to the other surface of the gear, and which maintains a first stable position, at which the spring is disposed in a first normal direction of the gear, so that the lock key protrudes by means of the spring, thereby allowing a locked state, or a second stable position, at which the spring is disposed in a second normal direction of the gear, so that the lock key is retracted, thereby allowing an open state.
