Description

Technical Field

[0001] This utility model relates to the field of lithium-ion battery pack assembly modules, specifically a lithium-ion battery pack assembly module. Background Technology

[0002] Soft-pack lithium-ion batteries have become the mainstream product of lithium-ion power batteries due to their good safety and low manufacturing cost. Through grouping and assembly, the batteries can achieve large-capacity energy storage and can be widely used in electric bicycles, electric vehicles, energy storage and other fields.

[0003] Chinese patent CN202871922U discloses a lithium-ion battery pack assembly module, including a battery frame, current collectors, and an insulating cover. The battery frame is rectangular, with insulating partitions perpendicular to the frame plate around its interior perimeter. A positive current collector and a negative current collector are located at the top of the battery frame, each with threaded holes. A base with bolt through holes is located at the bottom of the battery frame. The current collectors are positioned above the positive and negative current collectors. An insulating cover slot is located in the center of the top of the battery frame. Insulating covers are mounted above the current collectors corresponding to the positive and negative current collectors, and are fixed to the insulating cover slot. Heat pipe channels are provided in the insulating cover slot. This invention can protect the lithium-ion battery pack assembly module, facilitate series and parallel connection of batteries, and dissipate heat generated during battery charging and discharging.

[0004] When the lithium-ion battery of the aforementioned patent is installed into the assembly module, workers need to use fasteners to fix the lithium battery in the assembly module, but this fixing method increases the labor cost. Utility Model Content

[0005] The purpose of this utility model is to provide a lithium-ion battery pack assembly module. The module includes a fixing block positioned on both sides of an insertion slot. The fixing block has side baffles and a connecting spring. A limit block is located at the end of the connecting spring furthest from the fixing block. Rotary bearings are located on both sides of the limit block, with the other end connected to the side baffle. When the user inserts the lithium-ion battery into the insertion slot, the limit block is compressed by the lithium-ion battery, causing the connecting spring to contract and abut against the outer surface of the lithium-ion battery. Once the lithium-ion battery is fully inserted, the limit block loses pressure, and the connecting spring pushes the limit block out again, abutting against the upper outer surface of the lithium-ion battery, thus securing the battery in the insertion slot. This solves the problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a lithium-ion battery pack assembly module, comprising an assembly module having an insertion slot, fixing blocks on both sides of the insertion slot, and a connecting spring disposed on the fixing blocks. A limit block is provided at the end of the connecting spring away from the fixing blocks. A side baffle is provided on the fixing blocks, and a rotary bearing is provided on the side baffle. The rotary bearing is connected to the limit block at the end away from the side baffle. A rectangular groove is provided in the assembly module at a corresponding position of the insertion slot, and a fixing plate is disposed within the rectangular groove. A through hole is provided on the fixing plate.

[0007] Preferably, a magnet is provided at one end of the fixing plate, and the magnet is bonded to the fixing plate.

[0008] Preferably, the fixing plate has heat dissipation holes, and the heat dissipation holes are integrally formed with the fixing plate.

[0009] Preferably, the assembly module is provided with a first connecting block at its bottom end, and the first connecting block is welded to the assembly module.

[0010] Preferably, the assembly module has a second connecting block at the end away from the first connecting block, and the second connecting block is welded to the assembly module.

[0011] Preferably, both the second connecting block and the first connecting block have bolt holes.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This invention features a fixing block on an assembly module, positioned on both sides of an insertion slot. The fixing block has side baffles and a connecting spring. A limit block is located at the end of the connecting spring furthest from the fixing block. Rotary bearings are located on both sides of the limit block, connecting to the side baffles at the other end furthest from the limit block. When a user inserts a lithium-ion battery into the insertion slot, the limit block is compressed by the lithium-ion battery, causing the connecting spring to contract and abut against the outer surface of the lithium-ion battery. Once the lithium-ion battery is fully inserted, the limit block loses pressure, and the connecting spring pushes it out again, abutting against the upper outer surface of the lithium-ion battery, thus securing the battery in the insertion slot. This effectively avoids the need for fasteners to secure the lithium-ion battery in the assembly module after installation, a method that increases manpower consumption. Attached Figure Description

[0021] In this embodiment, please refer to Figures 1-3When the user inserts the lithium-ion battery into the insertion slot 4, the limiting block 8 is compressed by the lithium-ion battery and the connecting spring 7 during the insertion process, so that the limiting block 8 abuts against the outer surface of the lithium-ion battery. When the lithium-ion battery is completely inserted into the insertion slot 4, the limiting block 8 loses pressure, and the connecting spring 7 pushes the limiting block 8 out again. The limiting block 8 abuts against the upper outer surface of the lithium-ion battery, and the lithium-ion battery is locked in the insertion slot 4. Then the fixing plate 12 is pushed into the rectangular slot 11. At this time, the limiting block 8 bounces up again due to the pushing of the fixing plate 12, and the limiting block 8 abuts against the fixing plate 12, thus completing the fixing of the lithium-ion battery.

[0022] Working principle: When the user inserts the lithium-ion battery into the insertion slot 4, the limiting block 8 is compressed by the lithium-ion battery and the connecting spring 7 during the insertion process, so that the limiting block 8 abuts against the outer surface of the lithium-ion battery. When the lithium-ion battery is fully inserted into the insertion slot 4, the limiting block 8 loses pressure, and the connecting spring 7 pushes the limiting block 8 out again. The limiting block 8 abuts against the upper outer surface of the lithium-ion battery, locking the lithium-ion battery in the insertion slot 4. Then, the fixing plate 12 is pushed into the rectangular slot 11. At this time, the limiting block 8 bounces back due to the pushing of the fixing plate 12, and the limiting block 8 abuts against the fixing plate 12, completing the fixing of the lithium-ion battery.
