[0002] A lithium-ion battery is a type of battery that uses lithium metal or lithium alloy as the negative electrode material and a non-aqueous electrolyte solution. The working principle of a lithium-ion battery is based on a redox reaction. During charging, lithium ions are extracted from the positive electrode and inserted into the negative electrode through the electrolyte. During discharging, lithium ions are extracted from the negative electrode and return to the positive electrode through the electrolyte. During this process, electrons move through the external circuit, forming an electric current that powers the device. Moisture is one of the many factors that can cause battery failure. Moisture entering the battery can lead to short circuits, decreased battery performance, or even damage. Therefore, improving the waterproof performance of batteries is crucial for ensuring battery stability and extending their lifespan.

[0003] The existing technology still has the following shortcomings:

[0004] 1. Existing high-safety waterproof battery boxes for lithium batteries have poor waterproof performance during use. Current technology generally uses glue to waterproof the battery box. However, the waterproof glue is prone to aging and difficult to replace. Once the waterproof glue ages, it is easy to leak, and replacement is time-consuming and laborious.

[0005] 2. Existing high-safety waterproof battery boxes for lithium batteries still have the problem of being troublesome to maintain and replace during use. Because they need to be waterproof, opening the battery box is cumbersome and maintenance is troublesome. Utility Model Content

[0021] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0022] like Figures 1-4 As shown, this utility model provides a technical solution:

[0023] A high-safety waterproof lithium battery box includes a battery box body 1, a battery box cover 2 on the top of the battery box body 1, four mounting brackets 3 fixedly connected to the bottom of the battery box cover 2, two fixing blocks 4 fixedly connected to each side of the battery box body 1, and two fixing blocks 5 fixedly connected to each side of the battery box body 1. There is a gap between the two fixing blocks 4 and the two fixing blocks 5, and the mounting brackets 3 are located in the gap. The operator places the battery box cover 2 on top of the battery box body 1, aligns the four mounting brackets 3 with the gap between the fixing blocks 4 and the two fixing blocks 5, and then inserts the mounting brackets 3.

[0024] An adjusting screw 6 is threadedly connected to the middle of the fixing block 4. An adjusting block 7 is rotatably connected to one side of the adjusting screw 6. An adjusting knob 8 is fixedly connected to the side of the adjusting screw 6 away from the adjusting block 7. The adjusting block 7 is adapted to the mounting bracket 3. Then, the operator rotates the adjusting knob 8 to rotate the adjusting screw 6. When the adjusting screw 6 rotates, it drives the adjusting block 7 to move towards the mounting bracket 3. Since the adjusting block 7 and the mounting bracket 3 are adapted to each other, the adjusting block 7 drives the mounting bracket 3 to move downward, thus fixing the battery box cover 2 tightly.

[0025] A waterproof pad 9 is fixedly connected to the bottom of the battery box cover 2. The waterproof pad 9 is located between the battery box body 1 and the battery box cover 2. When the adjusting block 7 moves the mounting bracket 3 downward, the mounting bracket 3 moves the battery box cover 2 downward, so that the battery box cover 2 and the battery box body 1 clamp the waterproof pad 9 between them, thereby improving the waterproof effect.

[0026] A handle 10 is fixedly connected to the top of the battery box cover 2, allowing the operator to easily lift the battery box 1 by holding the handle 10, making it convenient for the operator to move it.

[0027] Several mounting blocks 11 are fixedly connected to the bottom of the battery box 1. The mounting blocks 11 have threaded holes in the middle. Operators can fix the mounting blocks 11 to the mounting position with bolts, which is convenient for disassembly and assembly.

[0028] The working principle of this utility model is as follows:

[0029] First, the operator places the battery inside the battery box 1, then places the battery box cover 2 on top of the battery box 1. The four mounting brackets 3 are aligned with the gap between fixing block 1 4 and fixing block 2 5, and then the mounting brackets 3 are inserted. Next, the operator turns the adjusting knob 8, causing the adjusting screw 6 to rotate. When the adjusting screw 6 rotates, it moves the adjusting block 7 towards the mounting bracket 3. Since the adjusting block 7 and the mounting bracket 3 are compatible, the adjusting block 7 moves the mounting bracket 3 downwards, securing the battery box cover 2. As the adjusting block 7 moves the mounting bracket 3 downwards, the mounting bracket... 3. Move the battery box cover 2 downwards, clamping the waterproof gasket 9 between the battery box cover 2 and the battery box body 1. While fixing the battery box cover 2, make the battery box cover 2 and the battery box body 1 more tightly connected, improving the waterproof performance. By rotating the adjustment knob 8, the adjustment block 7 can be moved away from the mounting bracket 3, making it easy to remove the battery box cover 2 for convenient battery installation and maintenance. The operator can easily pick up the battery box body 1 by holding the handle 10, making it easy to move. The operator can fix the mounting block 11 to the installation position with bolts, making disassembly and assembly convenient.
