[0022] Reference Figure 1-4 As shown, an insulating protection structure that is easy to disassemble is L-shaped as a whole, including a battery pack insulating protection plate 1 and a collection line insulating protection plate 2. The battery pack insulating protection plate 1 and the collection line insulating protection plate 2 are an integrated structure. The area of ​​the battery pack insulating protection plate 1 is larger than the area of ​​the collection line insulating protection plate 2. The battery pack insulating protection plate 1 and the collection line insulating protection plate 2 include mounting holes 3. The collection line insulating protection plate 2 includes heat dissipation holes 4. When in use, the battery pack insulating protection plate 1 is installed above the battery pack, and the collection line insulating protection plate 2 is installed on the side of the collection line. The heat dissipation holes 4 are used for heat dissipation of the battery pack and the collection line.

[0023] The heat dissipation hole 4 is in a long strip shape.

[0024] The easily disassembled insulating protective structure is made by the blister process.

[0025] It also includes a bracket mushroom head structure 10, one end of which fixes the top and side of the battery pack. The bracket mushroom head structure 10 corresponds to the mounting holes 3 on the battery pack insulation protection plate 1 and the collection line insulation protection plate 2. The battery pack and the easily disassembled insulation protection structure are fixed by the bracket mushroom head structure 10 and the mounting holes 3.

[0026] A groove 5 is provided on one side of the battery pack insulation protection plate 1 close to the collection line insulation protection plate 2 and on the other side away from the collection line insulation protection plate 2. A mounting hole groove 6 is provided in the groove 5. The mounting hole groove 6 is a groove structure relative to the groove 5. A mounting hole 3 is provided in the mounting hole groove 6. The mounting hole groove 6 contacts the battery pack. The battery pack insulation protection plate 1 protects the battery pack while reducing the contact area to avoid generating excessive heat.

[0027] A supporting groove 7 is provided on the battery pack insulation protection plate 1. The supporting groove 7 is concave downward and is a long strip-shaped groove. The supporting groove 7 is in contact with the battery pack. Similarly, the battery pack is protected while reducing the contact area to avoid generating excessive heat.

[0028] The collection line insulation protection plate 2 includes a support area 8 and a heat dissipation area 9. The support area 8 and the heat dissipation area 9 are alternating strip structures. The support area 8 is concave relative to the heat dissipation area 9. The heat dissipation hole 4 is located on the heat dissipation area 9 where the support area 8 connects with the collection line of the battery pack.

[0029] The installation method of the easily removable insulation protection structure and battery pack is as follows: first, cover the wider side of the insulation protection structure with the battery pack insulation protection plate 1 on the top of the manufactured battery pack, align the mounting hole with the position of the bracket mushroom head structure, and press the mounting hole position slightly in turn to make the bracket mushroom head structure pass through the mounting hole to achieve the position restriction, and complete the first side installation; secondly, bend the narrower side of the collection line insulation protection plate 2 along the bending edge 90°, and finally repeat the first side installation process to complete the second side installation. The disassembly process is: pinch the bracket mushroom head structure tightly in turn to make it close together, and make the bracket mushroom head structure pass through the mounting hole, and then remove it as a whole.

[0030] The utility model is assembled into one with the fixed battery pack through the bracket mushroom head structure, does not need to be processed with adhesive backing, and does not need other auxiliary parts for fixing. It is simple to operate and easy to install, provides reliable insulation protection, and is easy to disassemble and maintain repeatedly.

[0031] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
