When the battery case is mounted on the AGV, the plug does not protrude, reducing the space occupied by the entire lithium battery system, facilitating assembly of the entire lithium battery system with the vehicle and improving space utilization. At the same time, the various components are secured with self-riveted waterproof studs, providing a high-strength waterproof function. The battery case is also provided with a counterweight groove to maintain the balance and safety of the vehicle, greatly improving the stability and safety of the AGV during operation.

[0007] Furthermore, the embedding groove and the first plug are fixedly installed by riveting waterproof studs and screws, and a waterproof connector for the first plug input line is also provided inside the embedding groove.

[0008] Based on the above, the first plug is fixedly installed in the embedding groove by means of a pressure-riveted waterproof stud, and the circuit of the first plug is connected to the internal parts of the battery box through a waterproof connector, which saves space while improving the waterproof performance of the battery box.

[0009] Furthermore, a first maintenance window closed by a first maintenance window cover is provided above the embedding groove, and corresponding countersunk holes are provided above the embedding groove and around the first maintenance window cover. The countersunk holes cooperate with the riveted waterproof studs and screws to fix the first maintenance window cover on the first maintenance window.

[0010] Based on the above, when the parts of the embedded groove are damaged, they can be repaired by opening the first maintenance window cover, which facilitates the subsequent maintenance of the battery box and reduces the maintenance cost.

[0011] Furthermore, a frame for supporting an upper cover of the battery box is provided in the battery box, and the upper cover is fixedly matched with the frame by the riveted waterproof studs.

[0012] Based on the above, the frame is used to support the upper cover, making the structure of the battery box more stable. At the same time, the frame is fixed and matched with the upper cover by the riveted waterproof studs, thereby achieving a waterproof effect.

[0013] Furthermore, a second maintenance window is provided on the upper cover plate, and a second maintenance window cover is matched with the second maintenance window. The second maintenance window cover is fixedly installed to the upper cover plate by the cooperation of the riveted waterproof studs and screws, and a pull ring is provided on the second maintenance window cover.

[0014] Based on the above, the second maintenance window and the second maintenance cover are for facilitating maintenance of the interior of the battery box, and the pull ring can make the disassembly of the second maintenance cover more convenient.

[0015] Furthermore, a second plug and a third plug are provided on the upper cover plate. The second plug and the third plug are fixedly mounted on the upper cover plate by the riveted waterproof studs, and a waterproof connector is provided for incoming wires.

[0016] Based on the above, the second plug and the third plug are fixedly mounted on the upper cover plate to facilitate connection with the electrical components above the AGV, thereby powering the AGV. The waterproof connector improves the waterproof performance of the circuit switching.

[0017] Furthermore, an opening is provided at a position on the lower portion of the battery box that matches the counterweight slot, and the opening is fixed to the side cover by countersunk screws.

[0018] Based on the above, opening the side cover can connect with the counterweight slot, and then the weight of the counterweight slot can be adjusted.

[0019] Furthermore, the upper cover is also provided with a plurality of communication interfaces.

[0020] Based on the above, the communication interface is used to connect the lithium battery and the electrical components on the AGV to transmit signals to each other.

[0021] Furthermore, the inner wall of the battery box is also provided with reinforcing ribs.

[0022] Based on the above, the reinforcing ribs are used to enhance the structural stability of the battery box and can also be used to limit the position of the battery cell module.

[0023] In order to more clearly illustrate the above features of the present invention and the objectives to be achieved, the present invention will be further described below with reference to the accompanying drawings and specific embodiments. BRIEF DESCRIPTION OF THE DRAWINGS
