[0002] With the continuous development of technology, GPS positioning technology has been widely used in various fields. In the management and maintenance of batteries, in order to achieve real-time tracking and positioning of the batteries, it is usually necessary to install GPS positioning devices on the batteries. However, traditional installation methods often leave the GPS positioning devices directly exposed, which not only affects the appearance of the battery, but also makes the GPS positioning devices susceptible to interference and corrosion from the external environment, thereby affecting their service life and positioning accuracy.

[0003] To address these issues, some anti-corrosion installation structures for batteries have emerged on the market. However, these structures are often integrated with the battery, making it inconvenient to install and maintain GPS devices and other auxiliary equipment. Furthermore, some structures have poor sealing performance, failing to effectively protect GPS positioning devices from external environmental interference and corrosion. Utility Model Content

[0042] The usage process and working principle of this utility model technical solution are as follows:

[0043] In use, the user can install the GPS positioning device or other equipment to be installed on one side of the mounting plate 5. Then, the user can slide the mounting plate 5 with the equipment installed inside the outer shell 4 of the housing. During installation, ensure that the equipment is inside the formed auxiliary box 2. Next, the user can install the sealing cover 9 on top of the mounting plate 5 and the outer shell 4 of the housing. At the same time, the user can use the fixing screws to fix the sealing cover 9 to the combined auxiliary box 2, thereby ensuring that the equipment is sealed inside the auxiliary box 2. The auxiliary box 2 has good sealing performance, which helps to prevent the equipment from being affected by external interference or corrosion. After that, the user can install the combined auxiliary box 2 on one side of the battery body 1. During installation, the auxiliary box 2 is moved from top to bottom, and the protrusion on one side of the housing 4 of the housing is slid into the two mounting grooves 3. When the auxiliary box 2 moves, it will successively abut against the inclined surfaces of the first locking post 17 and the second locking post 18 to retract until the first locking post 17 corresponds to the first locking hole 14 and the second locking post 18 corresponds to the second locking hole 15. Under the action of the corresponding spring 19, the two first locking posts 17 and the second locking post 18 are retracted. The locking pin 18 can be inserted into the corresponding first locking hole 14 and second locking hole 15, thereby locking the auxiliary box 2. Since the first locking hole 14, the first locking pin 17, the second locking hole 15, and the second locking pin 18 adopt different shapes, it ensures that the auxiliary box 2 can be locked smoothly and quickly during installation, preventing it from getting stuck in the wrong hole. This reduces the difficulty of operating the equipment and ensures high user efficiency. When the user needs to disassemble the auxiliary box 2, the user only needs to lift it upwards using the lifting lever 23. Pull the slide bar 22. When moving, the slide bar 22 can pull the first traction rope 20 and the second traction rope 21 to pull the corresponding first locking post 17 and second locking post 18. The first locking post 17 and the second locking post 18 can be retracted into the corresponding first sliding cavity 16, at which time the auxiliary box 2 can be easily removed. When the user stops pulling the slide bar 22, the slide bar 22 will return to its original position under the action of the tension spring 26 and multiple springs 19. The two first locking posts 17 and the two second locking posts 18 will also extend again for subsequent installation and use.
