Description

Technical Field

[0001] This utility model belongs to the field of lithium battery module technology, and relates to a soft-pack lithium battery module. Background Technology

[0002] Lithium batteries are a type of battery that uses lithium metal or lithium alloy as the positive / negative electrode material and a non-aqueous electrolyte solution. Due to the highly reactive chemical properties of lithium metal, the processing, storage, and use of lithium metal require very high environmental standards. With the development of science and technology, lithium batteries have become the mainstream.

[0003] A lithium battery module that is easy to assemble is disclosed in Chinese patent CN215771383U. It includes a lithium battery module body, a connecting mechanism and a drying mechanism. The connecting mechanism is connected to the lithium battery module body. The connecting mechanism includes a connecting block, a trapezoidal insert, a telescopic rod, a spring, a slider, a locking rod and a push block. The connecting blocks are fixedly connected to both sides of the lithium battery module body. The lower surface of the connecting block has a trapezoidal slot and two symmetrically arranged grooves.

[0004] In the existing lithium battery module assembly process, trapezoidal inserts are inserted into trapezoidal slots, and locking rods are inserted into the slots to fix the trapezoidal inserts in place, thus completing the assembly of the battery module. However, when disassembling the battery module, the operator needs to simultaneously push four push blocks on both sides of the battery body, causing the two push blocks on the same side to move away from each other, so that the corresponding locking rods can disengage from the slots. Only then can the trapezoidal inserts move upwards and disengage from the trapezoidal slots, thus completing the disassembly. This makes the operation process inconvenient and reduces work efficiency.

[0005] To address the aforementioned problems, this utility model proposes a soft-pack lithium battery module. 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: As Figures 1-2 As shown, the technical solution adopted by this utility model is as follows: a soft-pack lithium battery module includes a lithium battery body 1, a fixing plate 2 is fixedly installed on both sides of the lithium battery body 1, a filter screen 3 is installed on both sides of the fixing plate 2, the fixing plate 2 is open at the top, the interior of the fixing plate 2 is filled with desiccant 4, and a sliding plate 5 is slidably installed on the top of the fixing plate 2.

[0024] A snap-fit ​​assembly is provided on the side wall of the fixing plate 2.

[0025] The snap-fit ​​assembly includes a movable plate 6, a snap-fit ​​plate 8, and a first spring 10. The snap-fit ​​plate 8 is fixedly installed on the bottom end of the side wall of the fixed plate 2, and the first spring 10 is fixedly connected to the top end of the side wall of the fixed plate 2. The other end of the first spring 10 is fixedly connected to the movable plate 6, and the bottom end of the movable plate 6 is rotatably connected to the side wall of the fixed plate 2. The top end of the movable plate 6 engages with the snap-fit ​​plate 8.

[0026] A slot 9 is provided on the side wall of the card plate 8, and an L-shaped snap-fit ​​plate is integrally formed and connected to the top of the movable plate 6. The outer surface of the L-shaped snap-fit ​​plate is arc-shaped. The bottom end of the card plate 8 is arc-shaped, and the outer surface of the L-shaped snap-fit ​​plate slides and engages with the bottom end of the card plate 8. The L-shaped snap-fit ​​plate is inserted into the inside of the slot 9.

[0027] A tie rod 7 is fixedly installed on the side wall of the movable plate 6.

[0028] Working principle:

[0029] When assembling the lithium battery body 1, align the bottom of the lithium battery body 1 with the top of another lithium battery body 1, move the lithium battery body 1 downwards to drive the clamping plate 8 downwards, and the inclined surface of the clamping plate 8 cooperates with the L-shaped clamping plate at the top of the movable plate 6. With the help of the first spring 10, the L-shaped clamping plate at the top of the movable plate 6 is clamped in the slot 9 of the clamping plate 8, thus completing the assembly of the lithium battery body 1.

[0030] When disassembly is required, simply pull the movable plate 6 with the lever 7 to disengage the L-shaped snap plate at the top of the movable plate 6 from the slot 9, thus completing the disassembly. The operation is simple.

[0031] The desiccant 4 inside the fixed plate 2 can absorb moisture through the filter screen 3, preventing moisture from affecting the lithium battery body 1. When the desiccant 4 needs to be replaced, simply pull out the sliding plate 5 to replace the desiccant 4.

[0032] Example 2: As Figures 3-5 As shown, the difference between this embodiment and Embodiment 1 is that the snap-fit ​​assembly includes a connecting plate 11, a pull plate 12, and a limiting plate 14. The connecting plate 11 is fixedly installed on the side wall of the fixing plate 2, and the limiting plate 14 is fixedly installed at the bottom end of the connecting plate 11. The pull plate 12 is slidably installed inside the connecting plate 11 for limiting. A limiting groove is formed on the limiting plate 14, and the pull plate 12 is inserted into the corresponding limiting groove.

[0033] A second spring 13 is fixedly connected to one end of the pull plate 12 located outside the connecting plate 11, and the other end of the second spring 13 is fixedly connected to the side wall of the connecting plate 11. One end of the pull plate 12 located inside the connecting plate 11 is set with an inclined surface, and an inclined plate 16 is slidably installed inside the connecting plate 11 for limiting, and the inclined plate 16 is set with an inclined surface on one side corresponding to the pull plate 12.

[0034] When not installed, one end of the pull plate 12 is located inside the inclined groove of the inclined plate 16, and the inclined plate 16 and the inclined surface of the pull plate 12 slide together.

[0035] A third spring 15 is fixedly connected to the bottom of the inner side of the connecting plate 11, and the top of the third spring 15 is fixedly connected to the inclined plate 16.

[0036] Working principle:

[0037] In this embodiment, when the lithium battery body 1 needs to be assembled, the lithium battery body 1 is moved downward, which causes the limiting plate 14 to move downward. The limiting plate 14 contacts the inclined plate 16, causing the inclined plate 16 to move downward. Through the cooperation of the inclined plate 16 and the inclined surface of the pull plate 12, the pull plate 12 is moved outward of the connecting plate 11. After the limiting plate 14 moves downward a certain distance, under the reset action of the second spring 13, one side of the pull plate 12 is driven into the limiting groove of the limiting plate 14.

[0038] When disassembly is required, pull the pull plate 12 to disengage one side of the pull plate 12 from the limiting groove of the limiting plate 14 to complete the disassembly.

[0039] The remaining working process is the same as in Example 1.

[0040] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
