[0020] Reference Figures 1 to 3 , which is an embodiment of the electromechanical lock structure of the present invention, specifically:
[0021] An electric mechanical lock structure includes a movable plate 110, a first guide column 120, a rotating plate 130, a motor, a compression spring 140, a top plate 210, a front plate 220, and a bottom plate 230; the thickness of the movable plate 110 is arranged along the front-to-back direction, a slide groove 111 is arranged along the vertical direction on the movable plate 110, a clamping strip 112 is arranged on the left side of the movable plate 110, a locking strip 113 is arranged on the lower side of the movable plate 110, an inclined surface 114 inclined to the lower left is arranged on the lower side of the locking strip 113, and a rotating notch 115 is arranged on the lower right side of the movable plate 110; the top plate 210 is arranged above the clamping strip 112, the upper end of the compression spring 140 abuts against the top plate 210, and the lower end of the compression spring 140 abuts against the clamping strip 112; the first guide column 120 extends along the front-to-back direction, and the first The guide column 120 is slidably connected to the slide groove 111; the thickness of the rotating plate 130 is set along the front-to-back direction, and a fixing portion 131 is provided on the right side of the rotating plate 130, and the fixing portion 131 is fixedly connected to the rotating shaft of the motor; a rotating portion 132 is provided on the left side of the rotating plate 130, and the upper side of the rotating portion 132 abuts against the rotating notch 115; the front plate 220 is fixedly connected to the top plate 210, the front plate 220 is fixedly connected to the first guide column 120, the front plate 220 is fixedly connected to the body of the motor, and the front plate 220 is fixedly connected to the bottom plate 230; the thickness of the bottom plate 230 is set along the up-down direction, and a first through hole 231 is provided on the bottom plate 230, and the locking strip 113 passes through the first through hole 231; a step surface 116 is provided on the lower side of the movable plate 110, and the step surface 116 abuts against the upper surface of the bottom plate 230. When the electric mechanical lock structure is working, during the process of returning the mobile power supply, the external force acts on the inclined surface 114, overcoming the downward pressure of the compression spring 140, so that the movable plate 110 moves up, and the clamping strip 112 used for locking moves up accordingly; during the process of taking out the mobile power supply, the motor rotates, driving the rotating plate 130 to rotate, and the rotating part 132 moves the movable plate 110 upward through the rotating notch 115, and the clamping strip 112 used for locking moves up, and the mobile power supply can be taken out. The first guide column 120 guides the movable plate 110 to move in the vertical direction through the slide groove 111. When the movable plate 110 moves downward, when the step surface 116 abuts against the bottom plate 230, the downward movement stops. In the process of returning the mobile power supply of this electric mechanical lock structure, the movable plate 110 and the compression spring 140 work independently, and the participation of the motor is not required, so the impact on the motor during the return process is reduced. Therefore, the electric mechanical lock structure is simple in structure and more durable.

When there is only the first guide post 120, after the first guide post 120 is worn, the vertical movement of the movable plate 110 is easily deviated, and the movable plate 110 also shakes during the movement. Therefore, adding the second guide post 150 can better improve the service life of the guide mechanism and ensure the accuracy of the vertical movement of the movable plate 110 for a longer time.
