First, after the user puts the lithium battery into the charging box, the control panel is used to control the drive motor at the corresponding position to work. The drive motor can drive the first screw to rotate. The rotation of the first screw can drive the tooth plate and the vertical rod to move upward. The movement of the vertical rod can drive the first spring, the push sleeve and the guide block to move upward. During the movement of the guide block, the fixed cylinder and the cabinet door body can be pushed through the arc guide groove to rotate along the bearing on the support sleeve, so that the cabinet door body can be closed with the front of the fixed frame under the action of rotation, so as to shield and protect the front of the lithium battery and the charging box; B.

[0017] 3. The present invention provides a piston, an air guide cylinder and a hollow rubber pad. When the cabinet door body and the fixed frame are closed, and the T-shaped movable rod is pushed by the vertical rod to move upward, the piston can be driven to move upward along the inner cavity of the air guide cylinder. The movement of the piston can compress the air inside the air guide cylinder, so that the air can be input into the hollow rubber pad, and the volume of the hollow rubber pad can be expanded, so that the cabinet door body and the fixed frame can be effectively sealed, thereby effectively preventing rainwater from entering the charging box, ensuring that the charging operation of the lithium battery can be carried out stably. The rubber ring is provided to effectively improve the sealing of the contact between the piston and the air guide cylinder. The second spring is provided to compress the second spring during the upward movement of the piston, so that the second spring can generate tension on the piston, thereby facilitating the subsequent downward movement and resetting of the piston.

[0018] 4. The present invention, through the arrangement of the coil spring and the fixed seat, can apply pressure to the coil spring inside the fixed seat during the process of the rotating shaft being pulled and rotated by the steel rope, so that the coil spring can generate a reaction force on the rotating shaft, so that the subsequent coil spring can drive the rotating shaft to rotate and reset. Through the arrangement of the supporting cross plate, the purpose of supporting and guiding the movable guide rod is achieved, and the movable guide rod is prevented from being offset and tilted under the action of movement.

First, after the user places the lithium battery (20) into the charging box (12), the control panel (8) is used to control the driving motor (15) at the corresponding position to operate. The driving motor (15) can drive the first screw (16) to rotate. The rotation of the first screw (16) can drive the tooth plate (18) and the vertical rod (19) to move upward. The movement of the vertical rod (19) can drive the first spring (45), the pushing sleeve (44) and the guide block (47) to move upward. During the movement of the guide block (47), the fixed cylinder (35) and the cabinet door body (2) can be pushed through the arc guide groove (46) to rotate along the bearing on the support sleeve (36), so that the cabinet door body (2) can be closed with the front of the fixed frame (3) under the action of rotation, thereby shielding and protecting the lithium battery (20) and the front of the charging box (12); B. At the same time, under the continuous action of the vertical rod (19), the first spring (45) can be compressed and can contact the bottom of the T-shaped moving rod (33), thereby pushing the T-shaped moving rod (33) to move upward. During the movement of the T-shaped moving rod (33), the rotating shaft (38) can be pulled through the steel rope (29) to rotate, so that the rotating shaft (38) can unwind the steel rope (29); C. When the rotating shaft (38) rotates, the rotating disk (25) can be driven to rotate. When the rotating disk (25) rotates, the first clamping block (10) can be pushed to move through the push rod (26), so that the first clamping block (10) can be inserted into the first clamping hole (13) on the fixed frame (3) under the action of movement, so as to effectively lock and limit the cabinet door body (2) and the right side of the fixed frame (3); D. At the same time, during the rotation of the turntable (25), the guide grooves (40) at both ends can be driven to rotate. When the guide grooves (40) rotate, the two sets of movable guide rods (27) can be pushed to move away from each other. When the movable guide rods (27) move, the second clamping block (11) can be pushed to move until the second clamping block (11) can be inserted into the second clamping holes (14) on both sides of the fixed frame (3) under the action of movement, thereby effectively locking and limiting the cabinet door body (2) and the two sides of the fixed frame (3), effectively increasing the difficulty of violent opening by criminals, and improving the overall anti-theft safety.
