As shown in fig. 1, the electronic lock of the present invention includes a lock body 100, where the lock body 100 includes a bottom plate 101, a housing 102 and a cover plate 103, two ends of the housing 102 are open, and the bottom plate 101 and the cover plate 103 respectively cover the upper and lower ends of the housing 102.

In some preferred forms, the electromagnet 12 is configured to be capable of telescopic movement in response to a change in current. In some preferred manners, the electromagnet 12 is configured to include a telescopic movable part 121, and the latch 11 is operatively connected to the telescopic movable part 121, and may be fixedly connected or detachably connected, such as the latch 11 is snap-fit connected to the movable part or connected together by a screw or a bolt. In some preferred modes, as shown in fig. 2-3, the electromagnet 12 is installed on the bottom plate 101 of the lock mechanism, as shown in fig. 2, a fixing position 122 for fixing the electromagnet 12 is arranged on the shell 102, when the shell 102 and the bottom plate 101 are covered, the position of the electromagnet 12 can be fixed, the fixing position 122 forms an area on the shell 102, a space 123 capable of providing the electromagnet 12 for stretching and retracting is arranged in the area, and since the current magnitude can affect the magnetic magnitude of the electromagnet 12, the adsorption capacity of the electromagnet 12 can be adjusted by adjusting the current change, so that the stretching and retracting movement can be carried out. Specifically, as shown in fig. 2, the electromagnet 12 is configured to include a telescopic movable part 121, the telescopic movable part 121 is disposed in a space 123 formed by a fixed position 122 and capable of being extended and retracted, the telescopic movable part 121 is made of a magnetic material capable of being attracted by the electromagnet 12, the electromagnet 12 can control attraction or release of the telescopic movable part 121 by the electromagnet 12 through the magnitude and direction of current, or can control attraction or release of the telescopic movable part by only controlling the change of current in combination with a mechanical structure such as a spring, and the latch 11 is connected to the telescopic movable part 121, so that the latch 11 can perform telescopic movement synchronously with the telescopic movable part 121, and thus the latch 11 performs telescopic movement, thereby performing locking or unlocking operations.
