[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] The present invention will now be described in further detail with reference to the accompanying drawings:

[0024] Example 1 provides a battery clamping fixture, such as Figures 1-4As shown, it includes a crossbeam 1, a handwheel 3, a screw 31, and a hook 2; a pressure plate 11 that cooperates with the battery pack 5 is provided on the crossbeam 1; a nut 32 is provided on the crossbeam 1, and the screw 31 is installed on the nut 32; the handwheel 3 is installed on one side of the screw 31; the hook 2 is installed on the other side of the screw 31; the hook 2 cooperates with the receiving part 51 of the battery pack 5.

[0025] By rotating the handwheel 3, the position of the hook 2 is adjusted. The hook 2 and the pressure plate 11 cooperate to clamp the battery pack 5 and its receiving part 51, which can press the battery pack 5 to prevent the battery pack 5 from bulging during the inflation test. The structure is simple, reducing the requirement for additional parts to press the battery pack. It is easy to operate, and the battery pack 5 can be pressed or released by rotating the handwheel 3.

[0026] like Figure 2 A buffer pad 12 is provided on the lower side of the pressure plate 11. The buffer pad 12 can be made of silicone, rubber or suede, etc.

[0027] In one specific embodiment, the crossbeam 1 is a profile component, such as a 40 profile component, and a reinforcing member 13 is provided on the crossbeam 1, such as a flat iron with a width of 20mm and a thickness of 2.5mm, to enhance the strength of the crossbeam 1 and adapt to larger pressure tests.

[0028] Example 2, as Figure 3 and Figure 4 The beam 1 is also equipped with a guide member 33, which is slidably mounted on the crossbeam 1, and a nut 32 is mounted on the guide member 33. Guide members 33 are respectively provided on both sides of the crossbeam 1, the nut 32 is fixed on the guide member 33, the screw 31 is mounted on the nut 32, and two hooks 2 are respectively mounted on one screw 31.

[0029] The spacing between the hooks 2 on both sides can be adjusted by sliding the guide 33 to accommodate battery packs 5 of various sizes.

[0030] More specifically, the crossbeam 1 is provided with an elongated adjustment hole 15, through which the screw 31 passes. This facilitates the adjustment of the position of the screw 31 in the adjustment hole 15.

[0031] In Example 3, unlike Example 2, a limiting block 36 is provided on the guide member 33, and the limiting block 36 is located on the outside of the hook 2; the hook 2 faces inward. The hook 2 is rotatably mounted on the other side of the screw 31. When the handwheel 3 and the screw 31 are rotated, the limiting block 36 limits the hook 2, preventing the hook 2 from rotating and keeping the hook 2 facing the receiving part 51; in addition, when the hook 2 is subjected to force and partially deforms, it can be supported on the limiting block 36, which can strengthen the force on the hook 2.

[0032] Specifically, a first limiting member 34 is provided at one end of the screw 31, and the hook 2 is rotatably installed on the inner side of the first limiting member 34.

[0033] In use, first adjust the distance between the guide 33 and the two hooks 2 so that the hooks 2 are aligned with the receiving part 51 of the battery pack 5; adjust the relative position of the pressure plate 11 and the side of the battery pack 5. Next, rotate the handwheel 3 to gradually clamp the receiving part 51 with the two hooks 2; the pressure plate 11 presses against the side of the battery pack 5. Then, perform an airtightness test on the battery pack 5. After the test, release the hooks 2 by rotating the handwheel 3, and then remove the battery clamping fixture.

[0034] It is easy to operate and does not require additional tools such as screwdrivers; the structure is simple and does not require a custom workbench, and can be operated on a regular workbench or the ground; after the hook 2 is released, the guide 33 is confined within the adjustment hole 15, which has the effect of preventing detachment and avoiding parts from falling or being lost.

[0035] The hook 2 of this utility model can slide on the crossbeam 1 to a suitable distance, and then hook the hookable receiving part 51 of the battery pack 5 through the hook 2. Turn the two handwheels 3 and tighten them. It can be applied to various types of new energy battery packs 5 and quickly and effectively prevent the battery pack 5 from bulging when it is being filled and tested for air tightness.

[0036] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
