Description

Technical Field

[0001] This utility model relates to the field of battery technology, and in particular to a large-size battery structure that is easy to assemble and disassemble. Background Technology

[0002] Traditional button cells offer high efficiency as a primary screening tool for materials, but their simplified structure leads to performance deviations that require rigorous calibration. While micro-pouch cells are closer to practical applications, they are costly to develop and require large quantities of materials, especially new and expensive ones. The complex manufacturing and packaging processes of pouch cells may introduce additional variables during the development phase, affecting the reproducibility of results. Furthermore, pouch cells are prone to expansion or leakage during testing, particularly when testing high-energy-density materials, posing safety hazards.

[0003] Large-size batteries have a capacity between traditional button cells and micro-pouch cells, and their manufacturing process is much more convenient than that of pouch cells. However, when assembling large-size batteries, clamps are needed to apply a certain pre-tightening force to both ends of the electrodes, and the existing clamp structures are not convenient for assembling and disassembling the batteries.

[0004] Therefore, it is necessary to provide a large-size battery structure that is easy to assemble and disassemble to solve the above-mentioned technical problems. Utility Model Content

A screw is rotatably mounted on the second clamping plate, and a knob is threaded on the screw. A slot is provided on the first clamping plate, and the screw is embedded in the slot.

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments. The embodiments of the present invention include, but are not limited to, the following embodiments.

[0024] Example 1:

[0025] like Figure 1-4 As shown, this utility model provides a large-size battery structure that is easy to assemble and disassemble, including: a battery body 1 and a clamp. The battery body 1 is a large-size battery. The clamp includes a connecting plate 2, which has two parts, upper and lower. A first clamping plate 3 and a second clamping plate 4 are rotatably mounted on the connecting plate 2. The first clamping plate 3 and the second clamping plate 4 clamp and fix the battery body 1 between them. Limiting grooves 7 are provided on the sides of the first clamping plate 3 and the second clamping plate 4 that are close to each other. A screw 6 is rotatably mounted on the second clamping plate 4, and a knob 5 is threaded onto the screw 6. A slot 8 is provided on the first clamping plate 3, and the screw 6 is embedded in the slot 8. The battery body 1 is generally disc-shaped, and includes a battery body 11 that can store electricity. A battery top cover 12 and a battery bottom cover 13 are respectively installed on the top and bottom of the battery body 11. The battery top cover 12 and the battery bottom cover 13 are used as the positive and negative terminals of the battery. The edge of the battery body 1 is embedded and fixed in the limiting groove 7. An insulating cover is installed on the battery body 1. The insulating cover is used to insulate the contact parts between the battery body 1 and the first clamping plate 3 and the second clamping plate 4. The insulating cover includes an insulating upper cover 14 and an insulating lower cover 15. The insulating upper cover 14 is fastened to the battery body 1 from the upper and lower sides, covering the sides, top and bottom parts of the battery body 1. The insulating cover provides insulation to prevent the battery body 1 from short-circuiting during assembly. In use, after the battery body 1 is initially assembled according to the process, the insulating cover is fastened onto the battery body 1. Then, the first clamping plate 3 and the second clamping plate 4 are opened, with the opening angle allowing the battery body 1 to be embedded between them. The left and right sides of the battery body 1 are respectively inserted into the limiting grooves 7 on the first clamping plate 3 and the second clamping plate 4. The space between the first clamping plate 3, the second clamping plate 4 and the limiting grooves 7 is filled by the insulating cover. Rotate the first clamping plate 3 or the second clamping plate 4 to bring the screw 6 closer to the slot 8. Rotate the screw 6 to insert it into the slot 8. Then, rotate the knob 5 to bring one end of the first clamping plate 3 and the second clamping plate 4 closer together, fixing the battery body 1 between the first clamping plate 3 and the second clamping plate 4. The insulating cover can insulate the battery body 1 from the first clamping plate 3 and the second clamping plate 4 to prevent short circuits. This structure can easily clamp and fix the battery body 1. After clamping and fixing, the battery body 1 can be further assembled and tested, and the assembled battery body 1 can be easily disassembled. It has the advantages of simple structure and easy operation, and is suitable for widespread use.

[0026] By setting up a clamp including a connecting plate 2, a first clamping plate 3, a second clamping plate 4, a knob 5, a screw 6, a limiting groove 7, and a slot 8, the battery body 1 can be easily clamped and fixed, which can effectively improve the assembly and testing efficiency of the battery.

[0027] Example 2:

[0028] An insulating layer is coated inside the limiting groove 7 to further prevent short circuits caused by direct contact between the two poles of the battery body 1 and the first card plate 3 and the second card plate 4.

[0029] By setting an insulating layer in the limiting groove 7, the insulation performance of the first card plate 3 and the second card plate 4 can be improved.

[0030] Example 3:

[0031] like Figure 3 As shown, an insulating pad 9 is installed in the limiting groove 7. The insulating pad 9 is used for insulation between the battery body 1 and the limiting groove 7, which can further prevent the battery body 1 from directly contacting the two poles with the first clamping plate 3 and the second clamping plate 4, thus preventing short circuits. At the same time, the insulating pad 9 is made of flame-retardant rubber material, which has a certain degree of deformability. When the battery body 1 is embedded in the limiting groove 7, the flexible deformation of the insulating pad 9 can prevent the battery body 1 from rigidly contacting the limiting groove 7, thus preventing wear or even damage to the battery body 1.

[0032] By installing an insulating pad 9 inside the card slot 7, the insulation performance of the first card plate 3 and the second card plate 4 is improved, and the battery body 1 can be protected to a certain extent.

[0033] Example 4:

[0034] like Figure 4 As shown, gears 16 are fixedly installed at the ends of the first card plate 3 and the second card plate 4 that are close to each other. The two gears 16 mesh, so that the first card plate 3 and the second card plate 4 can rotate uniformly with their rotation axis as the axis, that is, the included angle between the first card plate 3 and the connecting plate 2 and the included angle between the second card plate 4 and the connecting plate 2 can be kept consistent.

[0035] By installing gears 16 at the ends of the first card plate 3 and the second card plate 4 that are close to each other, the included angle between the first card plate 3, the second card plate 4 and the connecting plate 2 can be kept consistent.

[0036] Working principle: In use, after the battery body 1 is initially assembled according to the process, the first clamping plate 3 and the second clamping plate 4 are opened, and the edge of the battery body 1 is inserted into the limiting groove 7 on the first clamping plate 3 and the second clamping plate 4. The first clamping plate 3 or the second clamping plate 4 is rotated to bring the screw 6 closer to the slot 8. The screw 6 is rotated to insert the screw 6 into the slot 8. Then the knob 5 is rotated to bring one end of the first clamping plate 3 and the second clamping plate 4 closer together, and the battery body 1 is clamped and fixed between the first clamping plate 3 and the second clamping plate 4. Then the battery body 1 can be followed up with subsequent assembly and testing processes.
