Description

Technical Field

[0001] This utility model relates to the technical field of battery sheet metal boxes, and in particular to a waterproof battery sheet metal box with strong protective capabilities. Background Technology

[0002] To enhance overall protection, battery pack sheet metal boxes are typically assembled using sheet metal panels. To ensure waterproofing, sealant is usually applied to the joints. However, existing battery pack sheet metal boxes often use screws to secure the box to the cover during sealing. These screws can penetrate the sealant, causing the sealant to loosen at the connection point with the battery pack. This allows external moisture to seep into the battery pack through the gaps, affecting battery lifespan. To address these issues, this application provides a waterproof battery sheet metal box with enhanced protection. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] Existing battery pack sheet metal boxes typically use screws to secure the box body and cover during the sealing process. However, these screws can penetrate the sealant, causing the sealant to loosen at the bond point with the battery pack. This allows external moisture to seep into the battery pack through the gaps, affecting battery lifespan. To address this issue, this application provides a waterproof battery sheet metal box with strong protective capabilities. Please refer to... Figures 1-4 This embodiment provides a waterproof battery box with strong protective capabilities, solving the technical problem of water leakage at the connection points of sheet metal locking screws. The device includes a sheet metal shell 1 as a supporting base, and a sealing mechanism 2 for improving the sealing performance of the battery pack is provided at the top of the sheet metal shell 1. The sealing mechanism 2 improves the overall sealing performance of the battery, thereby extending the battery's service life.

[0025] In existing battery manufacturing processes, battery packs are typically encased in sheet metal and sealed at the joints with sealant. To enhance the overall protection of the battery pack, locking screws are used to secure these joints. However, existing locking screws require penetrating the sealant between the battery pack and the top cover during the fixing process. Penetrating the dried sealant affects the adhesion between the sealant and the inner wall of the battery pack, thus impacting the sealing effect and potentially causing leakage. To address this issue, a sealing mechanism 2 is proposed. The sealing mechanism 2 includes a battery pack top cover 21 slidably connected to the top of the sheet metal housing 1. Several reinforcing blocks 22 are equidistantly fixed around the outer perimeter of the battery pack top cover 21. Both the sheet metal housing 1 and the reinforcing blocks 22 have through-holes 23 for connecting screws. Locking screws 24 are screwed into the inner sides of each of the screw holes 23. A sealing block 25 is fixedly connected to the bottom of the battery pack top cover 21.

[0026] To prevent the locking screw 24 from contacting the sealing block 25 during its penetration of the battery pack top cover 21 and the sheet metal housing 1, and thus to prevent the sealant on the sealing block 25 from being affected by the fixing of the locking screw 24, the bottom of the reinforcing block 22 is lower than the bottom of the battery pack top cover 21.

[0027] To improve the overall sealing performance of the battery pack, the top of the sealing block 25 is attached to the inner wall of the sheet metal housing 1, and several reinforcing blocks 22 are attached to the inner wall of the sheet metal housing 1. The mating screw holes 23 on the sheet metal housing 1 and the reinforcing blocks 22 correspond to each other.

[0028] The battery pack is installed on top of the sheet metal housing 1 via the top cover 21. During this process, the sealing block 25 and the reinforcing block 22 installed on the top cover 21 will fit against the inner wall of the sheet metal housing 1. The operator applies sealant to the space between the sealing block 25 and the inner wall of the sheet metal housing 1 using a glue gun. After the sealant dries completely, the locking screw 24 is screwed into the mating screw holes 23 on the sheet metal housing 1 and the reinforcing block 22 to fix the sheet metal housing 1 and the reinforcing block 22. This process does not affect or damage the dried sealant, thus ensuring the sealant's sealing performance.

[0029] Example 2

[0030] Based on Example 1, which solved the technical problem of water leakage at the sheet metal locking screw connection, Example 1 still has the problem of a cumbersome battery pack assembly process. Figures 1-4 As shown, the specific implementation process is as follows: During battery assembly, the placement of components inside the battery pack is not fixed, making the assembly process cumbersome and complex. Therefore, several battery clips 3 are set inside the sheet metal housing 1. Several battery clips 3 are fixedly connected at equal intervals inside the sheet metal housing 1. The battery clips 3 limit the position of the components inside the battery pack. The top cover 21 of the battery pack is fixedly connected to two symmetrical handle adapter seats 4. A handle 5 is rotatably connected between the two handle adapter seats 4. The handle 5 is specially set to make the transportation of the battery pack more convenient.
