An electric vehicle battery box and its locking mechanism

Abstract

The invention discloses an electric vehicle battery box and a locking mechanism thereof, comprising a lock head, a lock sleeve is axially inserted in an inner hole of the lock head, and a pressing type uniformly distributed along the circumferential direction of the lock head is arranged between the lock sleeve and the lock head Self-locking unit; the self-locking unit includes a control shaft inserted on the front end surface of the lock head for axial limit movement, and a stop body assembled between the control shaft and the lock sleeve, the outer peripheral surface of the lock sleeve has When the shaft moves forward to the locking position, the corresponding end of the stop body is clamped and top mounted between the lock sleeve and the control shaft to realize the locking of the lock head. When the shaft moves back to the unlocking position, the corresponding end of the stop body enters so that the stop body can be radially separated from the unlocking groove of the locking recess, and between the control shaft and the lock head, there is a forward, A return spring to prevent the force that controls the shaft to unlock. The locking mechanism and the electric vehicle battery box using the same have the advantages of convenient operation and stable locking effect.

Description

Technical field [0001] The invention relates to an electric vehicle battery box and a locking mechanism thereof. Background technique [0002] The battery box of an electric vehicle is the energy supply part of an electric vehicle.
