[0029] 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.
[0030] The present invention will now be described in further detail with reference to the accompanying drawings:
[0031] Example 1 provides a foldable battery clamping fixture, such as Figures 1-4 As shown, it includes a crossbeam assembly 1, a locking mechanism 3, a clamping mechanism 6, and a clamp 2; the crossbeam assembly 1 adopts a foldable structure;
[0032] The locking mechanism 3 is installed on both sides of the crossbeam assembly 1, and the locking mechanism 3 is provided with a clamping station 39 that cooperates with the battery pack 5.
[0033] The clamping mechanism 6 includes a pressure block 65 or a pressure plate disposed on one side of the crossbeam assembly 1;
[0034] The crossbeam assembly 1 includes a first crossbeam 11 and a second crossbeam 12 hinged to one side of the first crossbeam 11; the clamp 2 includes a clamping seat 23 and a clamping hook 24 that cooperate with each other; the clamping seat 23 and the clamping hook 24 are respectively disposed on the first crossbeam 11 and the second crossbeam 12.
[0035] After the clamp 2 is released, the first crossbeam 11 and the second crossbeam 12 can rotate relative to each other, folding the crossbeam assembly 1 to reduce space occupation and facilitate storage and movement; after the clamp 2 clamps the first crossbeam 11 and the second crossbeam 12, the battery pack 5 is clamped on the clamping station 39 of the locking mechanism 3, and the side of the battery pack 5 is pressed by the pressure block 65 or pressure plate of the pressing mechanism 6 to prevent bulging of the battery pack 5 during inflation testing.
[0036] More specifically, the first crossbeam 11 is hinged to the second crossbeam 12 via a hinge 21, such as a hinge, but not limited thereto. At least one set of clamping mechanisms 6 are provided at intervals on the crossbeam assembly 1.
[0037] The clamping seat 23 is provided on the first crossbeam 11. The clamping seat 23 is provided with a U-shaped or V-shaped clamping groove facing away from the clamping hook 24. The handle 25 is hinged to the second crossbeam 12. The clamping hook 24 is hinged to the handle 25 and cooperates with the clamping groove to realize the locking and unlocking operation of the clamping hook 24 and the clamping seat 23.
[0038] In Example 2, unlike Example 1, the crossbeam assembly 1 adopts a telescopic structure, with the first crossbeam 11 sleeved on the outside of the second crossbeam 12; a locking bolt (not shown in the figure) is provided on the first crossbeam 11. After loosening the bolt, the second crossbeam 12 can be slid into the first crossbeam 11 to accommodate the battery clamping fixture.
[0039] Example 3, as Figure 2 As shown, the locking mechanism 3 includes a support rod 31, with a through hole 34 on the outer side of the support rod 31; a pull pin 32 or a locking pin is slidably disposed on the through hole 34; and a clamping station 39 is disposed on the inner side of the pull pin 32. The battery pack 5 is locked in the clamping station 39 by the cooperation of the pressure block 65 and the pull pin 32.
[0040] Specifically, a first limiting member 33 is provided on the support rod 31 inside the clamping station 39. The battery pack 5 or its receiving part 51 is clamped between the first limiting member 33 and the pull pin 32.
[0041] More specifically, a handle 35 is provided on one side of the pull pin 32; a second limiting member 36 is provided on the other side to prevent the pull pin 32 from accidentally detaching or falling off. The second limiting member 36 may be an elastic ball.
[0042] Optionally, the receiving part 51 is provided with a receiving hole 52 that mates with the support rod 31. The support rod 31 is slidably mounted on the receiving hole 52, and the support rod 31 and the receiving hole 52 are clearance-fitted.
[0043] Example 4, as Figure 3 and Figure 4 As shown, the clamping mechanism 6 includes a nut 63 mounted on the crossbeam assembly 1 and a screw 61 that cooperates with the nut 63; the pressure block 65 is mounted on the screw 61.
[0044] A hand-tightening nut or handwheel 62 is provided on the outer side of the screw 61.
[0045] Specifically, the nut 63 and the guide ring 66 are respectively set on opposite sides of the crossbeam assembly 1; the screw 61 passes through the guide ring 66 to improve the stability of the movement of the screw 61 and the pressure block 65.
[0046] The pressing block 65 can be round or square.
[0047] The support rod 31 is installed on the outside of the battery pack 5 or its receiving part 51. A pull pin 32 is inserted into the through hole 34 of the support rod 31, and the battery pack 5 or its receiving part 51 is installed on the clamping station 39. If the receiving part 51 is provided with a receiving hole 52, the support rod 31 can be inserted into the receiving hole 52, and then the pull pin 32 can be inserted into the through hole 34 of the support rod 31 to set the battery pack 5 or its receiving part 51 on the clamping station 39.
[0048] The position of the pressure block 65 can be adjusted by rotating the handwheel 62, pressing the pressure block 65 into the desired position on the battery pack 5. This operation is convenient. When the battery pack 5 is inflated, two or more pressure blocks 65 can effectively prevent bulging at the required pressing position.
[0049] For easy carrying, the entire crossbeam assembly 1 is divided into two sections. The first crossbeam 11 and the second crossbeam 12 are connected in the middle by a hinge 21, and the first crossbeam 11 and the second crossbeam 12 are quickly connected by a high-tension quick clamp 2.
[0050] 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.
