The first piston assembly 300 is in sealing contact with the first chamber 101 in the circumferential direction, the first piston assembly 300 is retracted in the first chamber 101 by the retraction of the lock tongue 400, the first piston assembly 300 extends out, the extension of the lock tongue is achieved, the first piston assembly 300 stretches out and draws back to achieve extrusion and being extruded of hydraulic oil, and the extrusion and being extruded of the hydraulic oil achieve automatic energy storage and release of the energy storage assembly 500. For example, during a locking process: the lock tongue 400 is retracted, the first piston assembly 300 pushes hydraulic oil to move towards the second chamber 102, and the energy storage assembly 500 stores energy; after the lock tongue 400 is in place, the energy storage assembly 500 releases energy, the lock tongue 400 extends, hydraulic oil enters the first chamber 101 from the second chamber 102, and the first piston assembly 300 and the lock tongue 400 are pushed out. The stopper 200 is closed, and the pressures of the first chamber 101 and the second chamber 102 are kept unchanged, so that the latch 400 cannot perform telescopic movement, thereby completing the locked state. During the unlocking process: the locking element is opened and the bolt 400 can be compressed and extended. The energy storage assembly 500 may store oil pressure, elastic potential energy, or the like. The locking state and the unlocking state of the lock tongue 400 are not driven by additional power, so that energy is saved.

The switch of the blocking member 200 may be realized by pulling and inserting the blocking member 200 in the radial direction of the lock body 100, or may be realized by rotating the blocking member 200 at an angle within the lock body 100. The stop member 200 can be manually switched, or can be electrically or hydraulically controlled. For example, in an embodiment of the present utility model, the stop 200 is a hydraulic stop valve spool.

The first piston assembly 300 divides the first chamber 101 into an oil chamber and an air chamber in the first chamber 101, and in the locked state, the stopper 200 is closed, the lock tongue 400 cannot be retracted continuously, and the oil chamber cannot be compressed any more, so that the locking of the locking mechanism is ensured to be firm.

In one embodiment of the present utility model, the energy storage assembly 500 is an accumulator. During the retraction of the bolt 400, the accumulator absorbs hydraulic oil to store energy; during the extension of the bolt 400, the accumulator pushes out hydraulic oil to release energy. That is, the oil port of the accumulator communicates with the second chamber 102.

Additionally, as shown in fig. 1, in another embodiment of the present utility model, an energy storage assembly 500 includes: a second piston 501 and an elastic medium, the second piston 501 being disposed in the second chamber 102; an elastic medium is interposed between the second piston 501 and the end cap of the second chamber 102.

During the process of releasing energy from the energy storage assembly 500, the elastic medium releases energy, and hydraulic oil moves from the second chamber 102 to the first chamber 101, pushing the second piston 501 to move in the direction of the stop 200. In the locked state, after the shut-off member 200 is closed, the elastic medium and the second piston 501 remain stationary. During unlocking, the stop 200 is opened, and hydraulic oil may move from the first chamber 101 to the second chamber 102, or from the second chamber 102 to the first chamber 101.

A front end cover 104 and a rear end cover 103 are respectively disposed at two ends of the lock body 100, wherein the front end cover 104 is an end cover of the first chamber 101, and the rear end cover 103 is an end cover of the second chamber 102.

In other words, the adjustment of the space between the third piston assembly 503 and the rear end cover 103, and thus the initial compression amount of the elastic medium, can achieve tightness adjustment of the lock tongue 400, for example, the larger the space between the third piston assembly 503 and the rear end cover 103 is, the larger the force required by the lock tongue 400 in the locking process is, and the smaller the space between the third piston assembly 503 and the rear end cover 103 is, the smaller the force required by the lock tongue 400 in the locking process is. Wherein the circumference of the third piston assembly 503 is in sealing contact with the second chamber 102.

Wherein in other alternative embodiments of the present utility model, the third piston assembly 503 comprises a third piston disposed between the elastic medium and the end cap of the second chamber 102, and a third rod connected to the third piston, the third rod penetrating the end cap of the second chamber 102 and being threadedly connected to the end cap of the second chamber 102. The third rod is provided with a flat surface, a hexagonal or an internal hexagonal form for clamping by a spanner.

Specifically, the adjustment of the distance between the third piston and the rear end, that is, the distance between the third piston and the second piston 501 is adjusted by screwing and unscrewing the third rod from the threaded hole of the rear end cover 103, and the pretightening force of the elastic medium is adjusted.

For example, the second sloped surface 402 may have an inclination angle between 45 degrees and 80 degrees with respect to the third sloped surface. The lock tongue 400 adopts a structure with a conical end part, so that the lock tongue 400 can be matched with lock blocks 611 with different heights, and the lock blocks 611 with different heights of the battery frame can be locked through the lock tongue 400. In other words, even if there is a deviation in the height of the locking piece 611 on different battery frames, reliable locking can be ensured.
