[0029] Figure 1 It is a schematic structural diagram of the soft-pack battery pressurization test fixture provided by the embodiment of the present utility model from one perspective. Figure 2 It is a schematic structural diagram of the soft-pack battery pressurization test fixture provided by the embodiment of the present utility model from another perspective. Figure 3 It is a schematic structural diagram of the soft-pack battery pressurization test fixture provided by the embodiment of the present utility model from yet another perspective. Please refer to Figures 1 - 3 As shown, the embodiment of the present utility model provides a soft-pack battery pressurization test fixture, which includes a pressure support plate 1, a first clamping plate 2, and a second clamping plate 3 that are sequentially arranged in parallel from top to bottom. An adjustment structure 4 is installed on the pressure support plate 1. A support member 5 is provided between the first clamping plate 2 and the pressure support plate 1.

[0030] The adjustment structure 4 includes a bolt 41 and an adjustment nut 42. The bolt 41 is vertically installed on the pressure support plate 1. The first end of the bolt 41 is located on the side of the pressure support plate 1 close to the first clamping plate 2 for pressing against the first clamping plate 2. The second end of the bolt 41 is located on the side of the pressure support plate 1 away from the first clamping plate 2. The nut 42 is installed on the second end of the bolt 41.

[0031] The first clamping plate 2 and the second clamping plate 3 in this embodiment are used to place a soft-pack battery. There are no special restrictions on the sizes of the first clamping plate 2 and the second clamping plate 3 in this embodiment, and those skilled in the art can preset them in advance according to the size of the battery to be tested. A through hole is formed in the center of the pressure support plate 1 in this embodiment, and the bolt 41 passes through this through hole.

[0032] When the soft-pack battery pressure test fixture in this embodiment rotates the adjusting nut 42 clockwise so that the adjusting nut 42 moves towards the pressure support plate 1, the adjusting nut 42 presses against the pressure support plate 1, and the first end of the bolt 41 presses against the first clamping plate 2, so that the first clamping plate 2 compresses the elastic member 6. After the elastic member 6 is compressed, the distance between the first clamping plate 2 and the second clamping plate 3 decreases. When the adjusting nut 42 is rotated counterclockwise, the elastic member 6 releases the elastic force to push the first pressing plate 2 to move away from the second pressing plate 3, and the distance between the first clamping plate 2 and the second clamping plate 3 becomes larger.

[0033] When the soft-pack battery pressure test fixture in this embodiment is in use, the soft-pack battery to be tested is placed between the first clamping plate 2 and the second clamping plate 3, and then the adjusting nut 42 is rotated clockwise so that the first end of the bolt 41 presses against the first clamping plate 2. The first clamping plate 2 compresses the elastic member 6. After the elastic member 6 is compressed, the distance between the first clamping plate 2 and the second clamping plate 3 decreases, and the first clamping plate 2 and the second clamping plate 3 clamp the soft-pack battery to be tested. This test fixture can realize clamping the first clamping plate 2 and the second clamping plate 3 only by rotating the adjusting nut 42. The adjustment method is simple. When the soft-pack battery needs to be taken out after the test, the adjusting nut 42 is rotated counterclockwise. Under the action of the elastic force of the elastic member 6, the first clamping plate 2 will automatically rise and open, which is convenient for taking out the soft-pack battery to be tested.
