[0027] Workflow: When installing the battery pack body 1, first place the battery pack body 1 inside the waterproof box 2, connect the battery pack body 1 to the connector on the outside of the waterproof box 2, and waterproof the connector. Then, place the sealing plate 6 on top of the battery pack body 1, and use a caulking gun to apply caulking compound to the connection between the sealing plate 6 and the inside of the waterproof box 2. After the caulking compound solidifies, it forms the first sealing strip 7. Next, place the box cover 3 on top of the waterproof box 2, rotate the threaded cylinder 52 inside the fixing frame 51 to move the bolt 53 inside the positioning frame 55 and move the tightening plate 54 below the positioning frame 55. Then, rotate the bolt 53 to move the tightening plate 54 inside the positioning groove 56 and make it fit tightly against the positioning groove 56. At this time, the bottom end of the sealing ring 4 fits tightly against the top of the waterproof box 2. Then, the mounting screws can be... 10 is inserted into the elongated hole 9 and screwed into the inner side of the threaded groove 8. Adhesive is applied to the inner side of the elongated hole 9 and the outer side of the mounting screw 10 using a glue applicator. Once the adhesive solidifies, a sealing block 11 is formed. Finally, adhesive is applied to the connection between the cover 3 and the outer side of the waterproof box 2 using a glue applicator. Once the adhesive solidifies, a second sealing strip 12 is formed. This completes the waterproofing treatment of the battery pack body 1. The sealing block 11 and the second sealing strip 12 prevent water from entering the inner side of the waterproof box 2. The sealing plate 6 and the first sealing strip 7 isolate the battery pack body 1, providing secondary protection. This design greatly increases the waterproof performance of the waterproof box 2, effectively preventing water from entering the battery pack body 1. The design of the tightening component 5 makes the installation of the cover 3 more convenient and ensures that the sealing ring 4 fits tightly against the top of the waterproof box 2.
