Embodiment Construction

[0018] The embodiment of the battery box locking mechanism of the present invention: figure 1 , figure 2 As shown, it includes a lock head 1 and a lock sleeve 2 axially inserted in the inner hole of the lock head for guiding movement of the lock head 1 back and forth. The left and right sides of the lock head 1 are respectively connected to the left and right sides of the battery box through a linkage mechanism. Directional action lock tongue (not shown in this part of the figure). The rear end of the lock sleeve 2 is used to be fixed on the front panel of the battery box. The function of the lock head 1 is to drive the two lock sleeves by moving back and forth on the lock sleeve 2. The two lock tongues move correspondingly and are inserted and matched with the lock holes on the power compartment to lock or unlock the battery box. Between the lock sleeve 2 and the lock head 1, there are two push-type self-locking units evenly distributed along the circumferential direction of ...

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. The mileage and service life of an electric vehicle are closely related to the life of the battery box. Especially in the driving process of an electric vehicle, the stability and safety of the battery box are extremely important. [0003] Chinese Patent Document C202242929U discloses a battery box locking mechanism and a battery box using the locking mechanism. The locking mechanism is arranged on the front panel of the battery box, and the lock head is guided along the push-pull direction of the battery box in and out of the power compartment. Mobile and assembled on the battery box, the two sides of the lock are respectively connected by a linkage mechanism with lock tongues that move in the left and right directions of the battery box. Two locks are ...
