Description

Technical Field

[0001] This utility model relates to trays, and more particularly to an adjustable tray for cylindrical battery packs. Background Technology

[0002] The production process of lithium battery packs is divided into three stages: front-end, middle-end, and back-end. The purpose of the front-end process is to process the raw materials into electrode sheets, and the core process is coating. The purpose of the middle-end process is to process the electrode sheets into unactivated cells. The purpose of the back-end process is to test and package, and the core processes are formation and capacity testing.

[0003] The subsequent processes mainly include packaging, formation and capacity testing, testing and sorting, module assembly, and PACK assembly. Packaging involves placing the battery cells into a metal or pouch casing. Formation is the process of activating the positive and negative electrode materials inside the battery through charging and discharging, thus activating the battery. Capacity testing, after formation, involves cycling the battery through charging and discharging and testing various battery parameters, and then grouping the batteries according to the measured parameters. Module assembly and PACK assembly include testing the upper limit of the battery module, assembling the battery pack, and testing the battery pack before it leaves the production line. After this process, the battery basically meets the factory requirements.

[0004] When encapsulating lithium battery packs, metal or soft-pack shells need to be clamped and fixed using a tray. However, existing trays mostly use a fixed structure, which can only be adapted to a single type of shell, resulting in poor compatibility. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide an adjustable tray for cylindrical battery packs, which has the advantage of high adaptability.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is: an adjustable tray for a cylindrical battery pack, comprising a tray body and a limiting structure disposed on the inner side of the tray body. The limiting structure is used to clamp and fix the battery pack shell. The limiting structure includes a fixed base plate fixedly disposed on the inner side of the tray body, a movable top plate slidably disposed on the upper part of the fixed base plate, and a locking member for pressing and fixing the movable top plate and the fixed base plate. The fixed base plate is provided with a placement hole through it from top to bottom, and the movable top plate is provided with an adjustment hole through it from top to bottom. The adjustment hole is used to communicate with the placement hole.

[0007] With the above technical solution, during use, simply loosening the locking mechanism allows the movable top plate to move relative to the top of the fixed base plate, thereby changing the width of the portion connecting the adjustment hole and the placement hole. This adapts the tray to battery pack casings of different diameters, giving it high adaptability. Furthermore, using a tray designed as described above can significantly reduce the warehousing and financial pressures on lithium battery pack manufacturers.

[0008] Preferably, a support block is provided at the upper end of the fixed base plate, the support block extends into the adjustment hole, and the inner edge of the support block is flush with the edge of the placement hole.

[0009] Through the above technical solution, the support block set up as described above can increase the contact area with the battery pack shell, and provide more stable support for the battery pack shell.

[0010] Preferably, the movable top plate has an avoidance opening from top to bottom, and when the adjustment hole and the placement hole coincide vertically, the support block is housed in the avoidance opening.

[0011] The above technical solution involves creating an clearance opening on the movable top plate to accommodate the support block, which can then be used to clamp and limit the size of the battery pack casing, further enhancing the applicability of the tray.

[0012] Preferably, a limiting protrusion is provided on the inner side of the adjustment hole, and the limiting protrusion is located on the side of the adjustment hole away from the support block.

[0013] Through the above technical solution, the limiting protrusions and support blocks provided above can be used to clamp and limit the battery pack casing more stably.

[0014] Preferably, a storage groove is provided on the lower inner side of the tray body, the storage groove is coaxially connected with the placement hole, and the width of the storage groove is greater than the width of the placement hole.

[0015] The above technical solution involves creating a storage groove on the lower inner side of the tray to accommodate the lower part of the battery pack casing. This design allows the tray to be used with longer battery pack casings, further enhancing its versatility.

[0016] Preferably, a support column is provided at the lower end of the fixed base plate, the lower end of the support column abuts against the lower inner side of the pallet body, and a connecting bolt is provided at the lower outer side of the pallet body, the threaded section of the connecting bolt passing through the pallet body and threadedly connected to the support column.

[0017] Through the above technical solution, the support column can be used to support the fixed base plate, thereby increasing the distance between the lower inner side of the tray body and the fixed base plate, thus adapting to longer battery pack shells and further improving the applicability of the tray.

[0018] Preferably, a connecting sleeve is embedded at the lower end of the supporting column, and the threaded section of the connecting bolt is threadedly connected to the connecting sleeve.

[0019] By installing a stronger connecting sleeve at the lower end of the support column using the above technical solution, deformation or even damage to the support column can be effectively avoided, and the connection stability between the support column and the pallet body can be improved.

[0020] Preferably, a positioning groove is provided on the lower inner side of the pallet body, and the lower end of the support column is inserted into the positioning groove.

[0021] The above technical solution allows the positioning groove to support the lower end of the support column, making the installation of the support column more convenient.

[0022] Preferably, the movable top plate is provided with an upper adjustment hole running from top to bottom, and the fixed bottom plate is provided with a lower adjustment hole running from top to bottom. The lower adjustment hole is connected to the upper adjustment hole. The locking component includes a locking bolt. The head of the locking bolt abuts against the movable top plate, and the threaded section of the locking bolt passes through the upper adjustment hole and the lower adjustment hole and is threadedly connected to the support column.

[0023] With the above technical solution, during use, only the circumferential rotation of the locking bolt needs to be controlled to lock and loosen the movable top plate, making the adjustment process relatively convenient.

[0024] Preferably, the locking component further includes a locking sleeve, which is embedded in the upper end of the support column, and the threaded section of the locking bolt is threadedly connected to the locking sleeve.

[0025] By using the above technical solution, a higher strength locking sleeve is installed at the upper end of the support column, which can effectively prevent the support column from deforming or even being damaged, and can also improve the connection stability between the support column and the fixed base plate.
