Illustratively, the mounting locations 351 are holes, and the operating member 31 is provided with connecting posts that are in mating engagement with the holes. Of course, in other embodiments, the mounting location 351 may be a connection post, and the operation member 31 may be provided with a hole, which is not described herein.

Since the latch member 32 can move up and down in the first direction and move in the second direction, and the elastic member 33 extends in the second direction, if the latch member 32 is directly abutted against the elastic member 33, the elastic member 33 is easily twisted during the movement of the latch member 32, and the elastic function of the elastic member 33 is affected.

In order to solve the above-mentioned problem, the latch assembly 3 provided in this embodiment further includes a spacer guide 36, where the spacer guide 36 is disposed between the latch member 32 and the elastic member 33, one end of the elastic member 33 abuts against the spacer guide 36, the other end abuts against a wall of the accommodating cavity of the panel 11, and the spacer guide 36 is slidably engaged with the latch member 32. Specifically, when the latch member 32 moves along the guide groove 32211, the isolation guide 36 moves in the second direction under the action of the latch member 32, and thus the elastic member 33 can be compressed in the second direction, avoiding twisting the elastic member 33.

Fig. 11 shows a schematic partial structure of the latch assembly 3 according to the second aspect of the present embodiment. As shown in fig. 11 in combination with fig. 10, the spacer guide 36 includes a first guide portion 361, a second guide portion 362, and a stopper portion 363, the first guide portion 361 and the second guide portion 362 being vertically disposed, the stopper portion 363 being provided at the bottom of the second guide portion 362. The main body 322 of the latch member 32 includes a main body portion 3221 and a guide limit portion 3222, the guide limit portion 3222 is perpendicular to the main body portion 3221, and the main body portion 3221 is located on a plane in which the first direction and the second direction are located. The first guiding portion 361 of the isolation guide 36 is disposed parallel to and abuts against the main body portion 3221 of the latch member 32, for ensuring the smoothness of the motion of the isolation guide 36 in the second direction. The second guide portion 362 of the spacer guide 36 is disposed parallel to and abuts against the guide limit portion 3222 of the latch member 32 for enabling the latch member 32 to move in the first direction relative to the spacer guide 36. The limit portion 363 of the spacer guide 36 abuts against the bottom of the guide limit portion 3222 of the latch member 32 for limiting the lowermost position of the latch member 32 in the first direction.

Alternatively, the operating member 31 in both the first and second embodiments may be a button, and the movement of the driving latch member 32 is achieved by toggling the button. Further, the elastic member 33 in the first and second embodiments may be a spring.

The energy storage power supply capable of hiding the charge-discharge interface 20 can improve the appearance aesthetic property of the energy storage power supply, meet the requirements of intelligent science and technology users, and improve the dustproof and waterproof performance of the charge-discharge interface 20.
