[0014] A method for locking the door of a battery charging management cabinet, the method comprising the following steps: A. First, after the user places the lithium battery into the charging box, they can operate the drive motor at the corresponding position through the control panel. The drive motor can drive the first screw to rotate. As the first screw rotates, it can drive the toothed plate and the upright to move upward. The movement of the upright can drive the first spring, the push sleeve and the guide block to move upward. During the movement of the guide block, it can push the fixed cylinder and the cabinet door body to rotate along the bearing on the support sleeve through the arc guide groove. This causes the cabinet door body to close with the front of the fixed frame under the action of rotation, thereby shielding and protecting the front of the lithium battery and the charging box. B. At the same time, under the continuous action of the upright, the first spring can be compressed and can contact the bottom of the T-shaped moving rod, thus pushing the T-shaped moving rod to move upward. During the movement of the T-shaped moving rod, it can pull the rotating shaft through the steel rope to rotate, so that the rotating shaft can unwind the steel rope. C. Furthermore, during the rotation of the shaft, the turntable can be driven to rotate. While the turntable is rotating, the first locking block can be moved through the push rod, so that the first locking block can be inserted into the first locking hole on the fixed frame under the action of movement, thereby effectively locking and limiting the cabinet door body and the right side of the fixed frame. D. At the same time, the rotation of the turntable can drive the guide grooves at both ends to rotate. While the guide grooves are rotating, they can push the two sets of moving guide rods to move to the side away from each other. While the moving guide rods are moving, they can push the second locking block to move until the second locking block can be inserted into the second locking holes on both sides of the fixed frame under the action of movement. This can effectively lock and limit the cabinet door body and the two sides of the fixed frame, effectively increasing the difficulty for criminals to force open it and improving the overall anti-theft security.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention, through the arrangement of a drive motor, a first screw, a toothed plate, a vertical rod, a support sleeve, a first spring, a push sleeve, a guide block, an arc-shaped guide groove, and a fixed cylinder, can effectively drive the cabinet door body to rotate and close effectively with the fixed frame after the lithium battery is placed inside the charging box. This provides effective safety protection around the lithium battery. With the cooperation of the vertical rod, T-shaped moving rod, steel rope, rotating shaft, turntable, push rod, first locking block, and first locking hole, the right side of the cabinet door body and the fixed frame is locked and limited after they are closed. Simultaneously, with the cooperation of the turntable, guide groove, moving guide rod, second locking block, and second locking hole, both sides of the cabinet door body and the fixed frame are locked and limited after they are closed. This effectively improves the locking effect after the cabinet door body is closed, significantly increasing the difficulty for criminals to forcefully open it and enhancing overall anti-theft security.

[0016] 2. The present invention, through the arrangement of gears, a second screw, and a limiting block, enables the gear plate to drive the cabinet door body to close with the fixed frame during the upward movement of the gear plate. This rotation of the gear plate drives the gear and the second screw to rotate, and the rotation of the second screw drives the limiting block to move to the right. As a result, the limiting block extends in front of the lithium battery, effectively blocking and limiting the lithium battery, thereby effectively preventing the lithium battery from shifting inside the charging box.

[0017] 3. This invention, through the arrangement of a piston, an air guide cylinder, and a hollow rubber pad, allows the piston to move upward along the inner cavity of the air guide cylinder as the cabinet door body and the fixed frame are closed. This movement of the T-shaped moving rod, pushed upward by the upright, compresses the air inside the air guide cylinder, allowing it to enter the hollow rubber pad and expand. This effectively seals the cabinet door body and the fixed frame, preventing rainwater from entering the charging box and ensuring stable lithium battery charging. The rubber ring further enhances the sealing between the piston and the air guide cylinder. The second spring, compressed during the upward movement of the piston, creates tension on the piston, facilitating its subsequent downward repositioning.

[0018] 4. This invention, through the arrangement of a coil spring and a fixed base, applies pressure to the coil spring inside the fixed base during the rotation of the rotating shaft under the traction of the steel cable. This causes the coil spring to generate a reaction force on the rotating shaft, facilitating its subsequent rotation and reset. The support plate provides support and guidance for the moving guide rod, preventing it from shifting or tilting under the influence of movement. The support shaft and support plate provide support for the top of the cabinet door and the bottom of the first screw, preventing them from tilting due to force. The limiting groove and limiting block provide limiting and guiding between the upright and the push sleeve, preventing the push sleeve from rotating along the surface of the upright. The support base and base plate provide support for the bottom of the cabinet body. The protective baffle provides rain protection for the top of the cabinet body. The monitoring camera facilitates security monitoring of the area around the cabinet body. Attached Figure Description

[0025] Example 2: Based on Embodiment 1, the present invention is as follows: Figure 4 As shown, a second screw 22 is movably connected to the lower left side of the charging box 12 via a bearing.

[0031] Example 5: A method for locking the door of a battery charging management cabinet, the method comprising the following steps: A. First, after the user places the lithium battery 20 into the charging box 12, the user controls the drive motor 15 at the corresponding position through the control panel 8. The drive motor 15 drives the first screw 16 to rotate. While the first screw 16 rotates, it drives the toothed plate 18 and the upright 19 to move upward. The movement of the upright 19 drives the first spring 45, the push sleeve 44 and the guide block 47 to move upward. During the movement of the guide block 47, it can push the fixed cylinder 35 and the cabinet door body 2 to rotate along the bearing on the support sleeve 36 through the arc-shaped guide groove 46. This causes the cabinet door body 2 to close with the front of the fixed frame 3 under the action of rotation, thereby shielding and protecting the front of the lithium battery 20 and the charging box 12. B. At the same time, under the continuous action of the upright 19, the first spring 45 can be compressed and can contact the bottom of the T-shaped moving rod 33, thus pushing the T-shaped moving rod 33 to move upward. During the movement of the T-shaped moving rod 33, it can pull the rotating shaft 38 to rotate through the steel rope 29, so that the rotating shaft 38 can unwind the steel rope 29. C. During the rotation of the rotating shaft 38, the turntable 25 can be driven to rotate. While the turntable 25 is rotating, the first locking block 10 can be moved through the push rod 26. Under the action of the movement, the first locking block 10 can be inserted into the first locking hole 13 on the fixed frame 3, 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 rotated. While the guide grooves 40 are rotating, they can push the two sets of moving guide rods 27 to move to the side away from each other. While the moving guide rods 27 are moving, they can push the second locking block 11 to move until the second locking block 11 can be inserted into the second locking hole 14 on both sides of the fixed frame 3 under the action of movement. This can effectively lock and limit the cabinet door body 2 and the two sides of the fixed frame 3, effectively increasing the difficulty for criminals to open it by force and improving the overall anti-theft security.

10. A method for locking the door of a battery charging management cabinet according to any one of claims 1-9, characterized in that, The method includes the following steps: A. First, when the user puts the lithium battery (20) into the charging box (12), he controls the drive motor (15) at the corresponding position through the control panel (8). The drive motor (15) can drive the first screw (16) to rotate. When the first screw (16) rotates, it can drive the toothed plate (18) and the upright (19) to move upward. The movement of the upright (19) can drive the first spring (45), the push sleeve (44) and the guide block (47) to move upward. During the movement of the guide block (47), it can push the fixed cylinder (35) and the cabinet door body (2) to rotate along the bearing on the support sleeve (36) through the arc guide groove (46). This causes the cabinet door body (2) to close with the front of the fixed frame (3) under the action of rotation, thereby shielding and protecting the front of the lithium battery (20) and the charging box (12). B. At the same time, under the continuous action of the upright (19), the first spring (45) can be compressed and can contact the bottom of the T-shaped moving rod (33), thus pushing the T-shaped moving rod (33) to move upward. During the movement of the T-shaped moving rod (33), it can pull the rotating shaft (38) to rotate through the steel rope (29), so that the rotating shaft (38) can unwind the steel rope (29). C. During the rotation of the shaft (38), the turntable (25) can be driven to rotate. While the turntable (25) is rotating, it can push the first locking block (10) to move through the push rod (26). Under the action of movement, the first locking block (10) can be inserted into the first locking hole (13) on the fixed frame (3), and can 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 rotated. While the guide grooves (40) are rotating, they can push the two sets of moving guide rods (27) to move to the side away from each other. While the moving guide rods (27) are moving, they can push the second locking block (11) to move until the second locking block (11) can be inserted into the second locking hole (14) on both sides of the fixed frame (3) under the action of movement. This can effectively lock and limit the cabinet door body (2) and the two sides of the fixed frame (3), effectively increasing the difficulty for criminals to open it by force and improving the overall anti-theft security.
