Abstract
Description
Technical Field
[0001] This utility model relates to the field of battery pack assembly technology, specifically to a tooling for installing a battery pack handle positioning pin. Background Technology
[0002] Lithium-ion batteries have advantages such as high energy density, good cycle performance, and rapid charge and discharge capabilities, and are widely used in various fields such as new energy vehicles and energy storage. In practice, lithium-ion batteries are usually assembled into battery packs. To meet the needs of convenient portability and the ability to disassemble and replace or charge individually, handles are often provided on the outside of the battery pack casing for easy lifting. Currently, most battery pack handles are fixed to the battery pack cover. However, adding handles would significantly increase the overall size of the battery pack, resulting in a larger footprint. Therefore, to avoid significantly increasing the size of the battery pack, a hidden handle is often provided on the top cover. A mounting groove facing inwards from the cover is provided on the cover, and a locating pin passes through the back of the mounting groove, passing through the cover and the handle, thus fixing the handle to the cover and preventing it from protruding. Since the cover plate usually has an installation side on the circumference, and there are other structures such as explosion-proof valves on the cover plate, the installation space is limited and it is inconvenient to operate in this way of installing the positioning pin from the inside of the cover plate. Moreover, the positioning pin is usually inserted with an interference fit, making manual installation difficult. If there is plastic residue in the positioning pin installation hole when the cover plate is molded, it will further increase the installation difficulty. Utility Model Content

[0017] like Figures 1 to 4As shown, a battery pack handle positioning pin mounting fixture includes an inverted U-shaped body 1. The inverted U-shaped body 1 has a contoured notch 2 and a mounting notch 3. The shape of the contoured notch 2 matches the mounting groove of the handle 14 of the battery pack cover. A mounting step 4 is formed between the contoured notch 2 and the mounting notch 3. A positioning post 5 is provided between the mounting step 4 and the top of the inverted U-shaped body 1. A movable block 6 is movably fitted on the positioning post 5. The movable block 6 can move along the axial direction of the positioning post 5. The top of the inverted U-shaped body 1 has a threaded hole. A lead screw 7 is threaded into the threaded hole. One end of the lead screw 7 extends into the mounting notch 3, and the other end extends to the outside of the inverted U-shaped body 1. The lead screw 7 can be screwed in or out of the mounting notch 3 by rotating it. A positioning through hole 9 is provided at the bottom of the inverted U-shaped body 1. When using the installation fixture to clamp the locating pin 13, first place both ends of the handle 14 into the mounting groove, then place the installation fixture on the back 12 of the mounting groove, aligning the back 12 of the mounting groove with the contour notch 2, and aligning the locating through hole 9 on the fixture with the locating pin mounting hole on the mounting groove. Then insert one end of the locating pin 13 into the locating pin mounting hole of the mounting groove. Finally, rotate the lead screw 7 to screw it into the mounting notch 3. After screwing it in a certain distance, continue to screw it in. The lead screw 7 will push the moving block 6 towards the locating pin 13. Continue to screw the lead screw 7 in. When the moving block 6 contacts the locating pin 13, it will exert pressure on the locating pin 13. The lead screw 7 pushes the moving block 6, which in turn pushes the locating pin 13 to move, finally pressing the locating pin 13 into place. After the locating pin 13 is installed in place, rotate the lead screw 7 in the opposite direction to release the moving block 6 from the locating pin 13, and remove the installation fixture.
[0018] In some embodiments, the bottom of the movable block 6 is provided with a limiting hole 11, which limits the positioning pin 13 when the movable block 6 is pressed into place.
[0019] In some embodiments, the lead screw 7 extends to one end of the U-shaped body 1 and is connected to a handle 8, which facilitates the rotation of the lead screw 7.
[0020] In some embodiments, the top of the movable block 6 is provided with a limiting groove 10, which limits the movement of the lead screw 7 when the lead screw 7 pushes the movable block 6 to move.
[0021] In some embodiments, when the mounting fixture is used to install the positioning pin 13, the contoured notch 2 matches the back surface 12 of the mounting groove of the battery pack cover handle 14. Specifically, the notch surface of the contoured notch 2 matches the back surface 12 of the mounting groove, and the notch depth matches the groove depth of the mounting groove, meaning the mounting groove can be embedded in the contoured notch 2. The positioning through hole 9 is aligned with the positioning pin mounting hole of the mounting groove. The contoured notch 2 allows for quick matching and positioning of the mounting fixture and the mounting groove, making operation convenient.
[0022] In some embodiments, the distance between the lead screw 7 and the opening end of the mounting notch 3 is greater than the side height of the battery pack cover, so as to avoid the battery pack cover affecting the rotation of the lead screw 7.
