[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0027] Example: Please refer to Figures 1-6 This utility model provides a technical solution:

[0028] An AGV charger includes a housing 1, a protective recess 2 on the back of the housing 1, a charging contact 3 installed inside the protective recess 2, a movable frame 4 slidably connected inside the housing 1, an outlet mechanism 5 installed at the front end inside the housing 1, an organism 6 fixedly installed on the top of the movable frame 4, first closing doors 7 hinged to both the left and right ends of the front of the housing 1, second closing doors 8 hinged to the opposite ends of the two sets of first closing doors 7, and closing mechanisms 9 installed at both the left and right ends inside the housing 1.

[0029] First, in this embodiment, the specific structure of the export mechanism 5 is as follows:

[0030] The export mechanism 5 includes a first motor 501 fixedly installed inside the front end of the housing 1. A drive gear 502 is fixedly installed on the drive end of the first motor 501. A transmission rack 503 is fixedly installed on the left end of the bottom of the movable frame 4, and the transmission rack 503 meshes with the drive gear 502. Both ends of the movable frame 4 are slidably connected to the inner side wall of the housing 1 through telescopic guide rails 504. Auxiliary frames 505 are fixedly installed at the front end of the movable frame 4 and at the left and right ends of the bottom of the movable frame 4. The top of each set of auxiliary frames 505 is rotatably connected to a receiving wheel 506, and both sets of receiving wheels 506 are in contact with the bottom of the movable frame 4. When it is necessary to inspect and maintain the machine body 6 inside the housing 1, the first closing door 7 is opened by the closing mechanism 9, and the second closing door 8 is opened in conjunction, thereby opening the front of the housing 1. Then, the first motor 501 is started to drive the drive gear 502 to rotate. Under the transmission rack 503, the moving frame 4 is moved to the outside of the housing 1. At the same time, the telescopic guide rail 504 is extended and retracted, and the receiving wheel 506 rolls against the bottom of the moving frame 4, so that the moving frame 4 moves stably to the outside of the housing 1, thereby automatically moving the machine body 6 to the outside of the housing 1, which greatly improves the convenience of inspection and maintenance.

[0031] Then, in this embodiment, the specific structure of the door closing mechanism 9 is as follows:

[0032] The closing mechanism 9 includes frames 901 fixedly installed at the left and right ends inside the housing 1. Screws 902 are rotatably connected to the inner sides of both frames 901. Second motors 903 are fixedly installed at the rear ends of both frames 901, and the drive ends of both second motors 903 are fixedly connected to the rear ends of the screws 902. Screw nuts 904 are installed on the outer sides of both screws 902. Closing rods 905 are installed between both screw nuts 904 and the first closing door 7. The rear end of the closing rod 905 is rotatably connected to the bottom of the screw nut 904, and the front end of the closing rod 905 is rotatably connected to the bottom end of the first closing door 7 via a connector 906. A guide sleeve 90 is fixedly installed at the top front of the housing 1. 7. Guide wheels 908 are rotatably connected to the top of the two sets of second closed doors 8 and inside the guide sleeve 907. When the machine body 6 is inspected and maintained, the second motor 903 is started first to drive the lead screw 902 to rotate. Under the connection of the lead screw nut 904, the closing door linkage 905 is moved. Under the connection of the connector 906, the first closed door 7 can be rotated. When the first closed door 7 rotates, the guide wheel 908 rolls inside the guide sleeve 907, so that the second closed door 8 opens in conjunction with the rotation of the first closed door 7. This automatically controls the opening of the first closed door 7 and the second closed door 8, making it easier to move the machine body 6 to the outside of the box 1, which greatly improves the convenience of inspection and maintenance.

[0033] Furthermore, a first ventilation mesh 101 is installed on both the left and right sides of the enclosure 1, and a second ventilation mesh 102 is installed on both the left and right sides of the body 6. The first ventilation mesh 101 and the second ventilation mesh 102 ensure the heat dissipation effect inside the enclosure 1 and the body 6.

[0034] The mobile frame 4 has a positioning frame 401 fixedly installed at the rear end of the top. Rubber anti-collision heads 402 are fixedly connected to the left and right ends of the back of the positioning frame 401. A limit frame 403 is fixedly installed at the position corresponding to the rubber anti-collision heads 402 on the back of the inside of the housing 1. Fixing blocks 404 are fixedly installed at the left and right ends of the top of the mobile frame 4 and on the front of the body 6. The body 6 is clamped and fixed to the top of the mobile frame 4 by the fixing blocks 404 and the positioning frame 401. When the mobile frame 4 is retracted into the inside of the housing 1, the rubber anti-collision heads 402 and the limit frame 403 are used to limit and protect the movement. At the same time, the top of the limit frame 403 leaves enough space to facilitate the wiring and winding between the body 6 and the charging contact 3.

[0035] Secondly, two sets of ball bearing seats 601 are installed on both the left and right sides inside the housing 1, and the surfaces of multiple sets of ball bearing seats 601 are in contact with the surface of the machine body 6. When the machine body 6 is moved by the moving frame 4, the ball bearing seats 601 roll in contact with the surface of the machine body 6, thereby improving the stability of the movement. At the same time, when the machine body 6 is inside the housing 1, it is positioned on the left and right sides, so that the machine body 6 can work stably inside the housing 1.

[0036] Finally, a maintenance cover 602 is hinged to the top of the body 6, and a clamping frame 603 is fixedly installed on the top of the maintenance cover 602. A clamping block 604 is fixedly installed at the top of the box 1 at a position corresponding to the clamping frame 603. Two sets of auxiliary wheels 605 are rotatably connected to the left and right ends of the top of the clamping frame 603. A rolling rod 606 is fixedly installed at the top of the box 1 at a position corresponding to the auxiliary wheels 605, and multiple sets of auxiliary wheels 605 are in contact with the surface of the rolling rod 606. After the body 6 is moved to the outside of the box 1, the maintenance cover 602 can be opened directly, which facilitates the internal maintenance. When the body 6 retracts into the box 1, the auxiliary wheels 605 on the top of the clamping frame 603 roll in contact with the rolling rod 606, further improving its movement stability. At the same time, when the body 6 is inside the box 1, the clamping block 604 is in contact with the top of the clamping frame 603, so that the maintenance cover 602 is firmly closed, further ensuring the working stability of the body 6.

[0037] In this embodiment, the specific implementation scenario is as follows: When performing maintenance on the machine body 6, the second motor 903 is first started to drive the lead screw 902 to rotate. Under the connection of the lead screw nut 904, the closing door linkage 905 moves. Under the connection of the connector 906, the first closing door 7 can be driven to rotate. When the first closing door 7 rotates, the guide wheel 908 rolls inside the guide sleeve 907, so that the second closing door 8 opens in conjunction with the rotation of the first closing door 7, thereby automatically controlling the opening of the first closing door 7 and the second closing door 8. Then, the first motor 501 is started. The drive gear 502 rotates, and under the transmission of the rack 503, the moving frame 4 moves to the outside of the housing 1. At the same time, the telescopic guide rail 504 extends and retracts, and the receiving wheel 506 rolls against the bottom of the moving frame 4, so that the moving frame 4 moves stably to the outside of the housing 1. This allows the machine body 6 to be automatically moved to the outside of the housing 1. After the machine body 6 is moved to the outside of the housing 1, the inspection cover 602 can be opened directly, which facilitates the inspection and maintenance of its interior. The whole operation process is simple and convenient. This utility model greatly improves the convenience of inspection and maintenance through its design.
