Description

Technical Field

[0001] The utility model mainly relates to the technical field of lithium battery brackets, and in particular to an injection-molded bracket for splicing lithium battery packs. Background Art

[0002] An injection-molded bracket is used to connect lithium battery packs. Multiple battery cells are stacked inside the lithium battery pack, resulting in a relatively heavy overall structure. The existing split-structure injection-molded bracket is used, and reference is made to the existing patent (Announcement No.: CN221632752U) that discloses a bracket for connecting prismatic lithium batteries. A first accommodating groove is provided on the side of a first mounting bracket facing the second mounting bracket, and second accommodating grooves are provided on both sides of the second mounting bracket. A snap-fit ​​structure is provided on one side of the first mounting bracket and on both sides of the second mounting bracket. During assembly, a prismatic lithium battery is first placed in the first accommodating groove of the first mounting bracket. Then, one side of the second mounting bracket is snap-fitted to the first mounting bracket via the snap-fit ​​structure, securing the prismatic lithium battery in the first and second accommodating grooves. After multiple prismatic lithium batteries are sequentially placed on the second mounting brackets, two adjacent second mounting brackets are snap-fitted together via the snap-fit ​​structure. This spliced ​​bracket structure allows for the assembly of any number of prismatic lithium batteries, eliminating the need for specialized brackets. The structure offers high versatility and compatibility, reducing costs.

[0003] In the process of implementing this solution, the inventor used a snap-fit ​​structure to complete the assembly process of multiple first mounting frames and second mounting frames. The weight of a single lithium battery pack is relatively large. When the snap-fit ​​structure is used to splice multiple lithium battery packs with the first mounting frame and the second mounting frame, the snap-fit ​​structure is generally manufactured using the same injection molding material as the first mounting frame and the second mounting frame. During subsequent use, the snap-fit ​​design that relies on holes in the inner wall of the first mounting frame or the second mounting frame has a technical problem of insufficient structural strength. If the structural strength of the snap-fit ​​structure is to be improved, the size of the snap-fit ​​structure and the wall thickness of products such as the first mounting frame need to be enlarged, which will cause the size of the entire product to exceed the design requirements.

[0035] Refer to the attached Figure 1-4 The present invention provides an injection-molded bracket for splicing lithium battery packs, comprising the following structure:

[0036] There are multiple first mounting racks 1 , and a second mounting rack 4 is provided on the right side of the first mounting rack 1 .

[0037] The two ends of the strap 7 are respectively clamped with the inner sides of the left and right ends of the fastening ring 8.

[0038] In this embodiment, a first assembly slot 11 for assembling a lithium battery is fixedly provided on the inner side of the right end of the first mounting frame 1 .

[0039] The first assembly slot 11 on the first mounting frame 1 cooperates with the lithium battery for assembly, wherein the specific shape of the first assembly slot 11 is adjusted according to the appearance of the final assembled product.

[0040] In this embodiment, a plurality of first heat dissipation holes 2 are fixedly formed on the surface of the first mounting frame 1 , and a plurality of first grooves 3 are fixedly formed on the outer side of the first mounting frame 1 from top to bottom.

[0041] The first heat dissipation hole 2 is provided to facilitate the first mounting frame 1 to cooperate with the lithium battery assembled inside to dissipate heat. The first groove 3 and the second groove 6 are constrained by the strap 7 to complete the assembly process of the lithium battery by the first mounting frame 1 and the second mounting frame 4.

[0042] In this embodiment, a second assembly groove 41 for assembling a lithium battery is fixedly provided on the inner side of the left end of the second mounting frame 4 , and the second assembly groove 41 cooperates with the first assembly groove 11 .

[0043] The second assembly groove 41 provided on the second mounting frame 4 completes the assembly process of the second mounting frame 4 and the lithium battery. The second assembly groove 41 cooperates with the first assembly groove 11 to complete the assembly process of the second mounting frame 4 and the first mounting frame 1 outside the lithium battery.

[0044] In this embodiment, a plurality of second heat dissipation holes 5 are fixedly provided on the surface of the second mounting frame 4, and a plurality of second grooves 6 are fixedly provided on the outer side of the second mounting frame 4 from top to bottom. The number and size of the second grooves 6 are the same as those of the first grooves 3, and the second grooves 6 cooperate with the first grooves 3.
