Description

Technical Field

[0001] This utility model belongs to the field of battery module technology, and in particular to a lithium-ion battery module that is easy to assemble. Background Technology

[0002] Lithium battery packs are composite batteries, mainly composed of battery cells, battery protection boards, battery connectors, etc., which are assembled into the products required by customers through a series of battery welding and assembly processes. During the assembly of existing lithium battery packs, some are assembled by parallel splicing and then tied with cable ties, while others are assembled by mounting brackets and then fixed by welding. Although the existing assembly methods can improve their stability, they are cumbersome when disassembly is required and cannot be quickly disassembled and reassembled.

[0003] A search revealed a Chinese patent document (authorization announcement number CN217444559U) regarding a simplified lithium-ion battery module for energy storage. It includes a battery cell assembly and a support frame. An insulating layer is provided on the opposite sides of the battery cell assembly, and the battery cell assembly and the insulating layer are bound together by strapping. This method of assembling the battery pack using strapping and insulating layers makes subsequent disassembly and assembly difficult, and the assembly method has low stability. Therefore, there is an urgent need for a lithium-ion battery module that is easy to assemble to solve this problem. Utility Model Content

[0004] The purpose of this invention is to provide a lithium-ion battery module that is easy to assemble, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a lithium-ion battery module that is easy to assemble, comprising a mounting bracket for mounting the lithium-ion battery module and a lithium-ion battery, wherein a mounting plate is longitudinally fixedly mounted on one side of the mounting bracket, and a vertical groove is longitudinally formed on the side wall of the mounting plate.

[0006] Two convex blocks are installed on the side of the mounting bracket away from the mounting plate, corresponding to the vertical groove;

[0007] The mounting bracket has two symmetrical mounting slots on its side wall. A plug rod is slidably installed in the mounting slot. A push spring is fixedly installed on the inner wall of the mounting slot. The end of the push spring is fixedly connected to the end of the plug rod.

[0008] The top surface of the mounting bracket has a strip-shaped hole corresponding to the mounting groove and is connected to the mounting groove. A vertical rod is fixedly installed on the top surface of the insertion rod, and the vertical rod slides through the strip-shaped hole and extends to the top of the mounting bracket. The side wall of the mounting bracket has insertion holes corresponding to the insertion rod.

[0009] Preferably, a crossbar is fixedly installed between the two vertical bars.

[0010] Preferably, a slide plate is slidably mounted on the top surface of the mounting bracket via a slider, and two screws are threaded through the top surface of the slide plate.

[0011] Preferably, the top surface of the mounting bracket has two screw holes corresponding to the screw rod, and the screw rod is threaded into the screw holes.

[0012] Preferably, a limiting block is fixedly installed on the side wall of the insertion rod, and a limiting groove is formed on the inner wall of the mounting groove.

[0013] Preferably, the two limiting blocks fixedly installed on the side wall of the insertion rod are slidably connected to the inside of the limiting groove opened in the inner wall of the mounting groove.

[0014] Preferably, a rubber pad is fixedly bonded to the outer wall of the convex block, and the outer wall of the rubber pad slides against the inner wall of the corresponding vertical groove.

[0015] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0016] This easy-to-assemble lithium-ion battery module benefits from the structure of mounting bracket side wall mounting plates, vertical slots, and convex blocks. By inserting the convex block fixedly mounted on one mounting bracket side wall into the vertical slot opened on the side wall mounting plate of another mounting bracket, the two mounting brackets can be spliced ​​together. Furthermore, the cooperation between the convex block and the vertical slot will further improve the stability between the mounting brackets.

[0017] This easy-to-assemble lithium-ion battery module benefits from the design of structures such as insert rods, push springs, and vertical rods. Before the convex block is inserted into the vertical slot, it will move the vertical rod to retract the insert rod into the mounting slot. When the two mounting brackets are spliced ​​together by the convex block, the insert rod will be opposite the socket. At this time, releasing the vertical rod will push the insert rod into the socket through the push spring, thereby further improving the splicing stability of the mounting brackets.

[0018] This easy-to-assemble lithium-ion battery module, compared to existing technologies, allows for easier assembly and disassembly of lithium-ion batteries. Attached Figure Description

[0028] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0029] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0030] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0031] like Figures 1 to 6 The main structure of a lithium-ion battery module that is easy to assemble consists of a mounting frame 1 for mounting the lithium-ion battery module and a lithium-ion battery 2. A mounting plate 3 is fixedly mounted longitudinally on one side of the mounting frame 1, and a vertical groove 4 is opened longitudinally on the side wall of the mounting plate 3. The lithium-ion batteries 2 are evenly arranged inside the mounting frame 1.

[0032] On the side of the mounting bracket 1 away from the mounting plate 3, two convex blocks 5 are installed corresponding to the vertical groove 4. The vertical groove 4 is set in a concave shape. Therefore, the cooperation between the convex blocks 5 and the vertical groove 4 can improve the stability of the splicing between the two mounting brackets 1.

[0033] The mounting bracket 1 has two symmetrical mounting slots 6 on its side wall. A rod 7 is slidably installed in the mounting slot 6. A push spring 8 is fixedly installed on the inner wall of the mounting slot 6, and the end of the push spring 8 is fixedly connected to the end of the rod 7. The top surface of the mounting bracket 1 has a strip hole corresponding to the mounting slot 6 and communicates with the mounting slot 6. A vertical rod 9 is fixedly installed on the top surface of the rod 7, and the vertical rod 9 slides through the strip hole and extends to the top of the mounting bracket 1. The side wall of the mounting bracket 1 has a corresponding insertion hole for the rod 7. Thanks to the structure of the rod 7, push spring 8 and vertical rod 9, before the convex block 5 is inserted into the vertical slot 4, it will move the vertical rod 9 to drive the rod 7 to retract into the mounting slot 6. When the two mounting brackets 1 are spliced ​​by the convex block 5, the rod 7 will be opposite the insertion hole. At this time, releasing the vertical rod 9 will push the rod 7 into the insertion hole through the push spring 8, thereby further improving the splicing stability of the mounting bracket 1.

[0034] A horizontal bar 10 is fixedly installed between the two vertical bars 9. Thanks to the horizontal bar 10, the two vertical bars 9 can be moved synchronously by moving the horizontal bar 10, thereby controlling the two insert rods 7 to move synchronously into the mounting slot 6.

[0035] The top surface of the mounting bracket 1 is slidably mounted with a slide plate 11 via a slider 13, and two screws 12 are threaded through the top surface of the slide plate 11. The top surface of the mounting bracket 1 has two screw holes corresponding to the screws 12, and the screws 12 are threaded into the screw holes. Thanks to the structure of the slide plate 11 and screws 12, the top surfaces of the two assembled mounting brackets 1 can be reconnected via screws 12, thereby further improving the stability of the mounting bracket 1.

[0036] Limiting blocks 14 are fixedly installed on the side wall of the insertion rod 7, and limiting grooves are opened in the inner wall of the mounting groove 6. The two limiting blocks 14 fixedly installed on the side wall of the insertion rod 7 are slidably connected to the inside of the limiting grooves opened in the inner wall of the mounting groove 6. The limiting blocks 14 can effectively limit the sliding direction of the insertion rod 7.

[0037] A rubber pad is fixedly bonded to the outer wall of the convex block 5, and the outer wall of the rubber pad slides against the inner wall of the corresponding vertical groove 4. The rubber pad is attached between the outer wall of the convex block 5 and the inner wall of the vertical groove 4, which can further improve the stability of the convex block 5 and the mounting bracket 1.

[0038] Working principle

[0039] This easy-to-assemble lithium-ion battery module is used by first moving the crossbar 10, which drives the two vertical bars 9 to slide along the strip hole. The vertical bars 9 drive the insertion rod 7 to retract into the mounting groove 6 and compress the push spring 8. Then, the convex block 5 mounted on the side wall of one mounting bracket 1 is inserted into the vertical groove 4 opened on the side wall of the mounting plate 3 mounted on the side wall of another mounting bracket 1. In this way, the mounting bracket 1 is quickly assembled by the cooperation of the convex block 5 and the vertical groove 4. Then, the crossbar 10 is released. At this time, the push spring 8 pushes the insertion rod 7, which is fixed at its end, to be inserted into the insertion hole opened on the side wall of another mounting bracket 1. Then, the sliding plate 11 is pushed to move towards the other mounting bracket 1. When the screw 12 on the sliding plate 11 is aligned with the screw hole, the screw 12 is rotated to connect to the screw hole, thereby further improving the stability of the mounting bracket 1 assembly.
