[0002] The current battery assembly process for electric vehicles involves using a crane and an L-shaped lifting device to lift the battery from the side of the vehicle body for assembly.
[0003] However, the battery structures and dimensions vary significantly between different vehicle models, resulting in a wide variety of lifting tools with poor versatility. Frequent tool changes are necessary, making operation inconvenient. Furthermore, when lifting batteries using a crane, their considerable weight and inertia make them prone to collisions and paint damage when placed in narrow vehicle compartments. This also poses a safety hazard, as it increases the risk of fingers being pinched.
[0004] In summary, there is an urgent need to develop a battery assembly device that can achieve compatibility with various batteries during battery assembly or disassembly. Utility Model Content

As the battery approaches the assembly device, it is slowly aligned along the limiting blocks and then placed on the roller assembly. The battery assembly device is then pushed to the side of the electric vehicle. The battery is manually pushed onto the roller assembly to roll into the vehicle's battery compartment. The battery assembly device is then moved aside, and the battery cables are secured to the vehicle. The entire assembly process is complete.
[0022] When removing the battery, first take out the roller assembly on the battery assembly device. According to the battery model, place a predetermined number of shims so that the bottom of the battery compartment is slightly higher than the top surface of the roller assembly. Then put the roller assembly back in, and put the remaining shims on the material column. At this time, manually pull the battery from the battery compartment of the vehicle body to the roller assembly in the battery assembly device.

[0030] refer to Figure 1 This application provides a battery assembly apparatus, including:
[0031] Base plate 1,
[0032] Roller assembly 3, mounted on the base plate 1, is used to support the battery to be installed.
[0033] An adjustment component is placed at the connection between the base plate 1 and the roller assembly 3 to adjust the height of the roller assembly 3, so that the height of the upper surface of the roller assembly 3 is higher or lower than the height of the bottom of the battery compartment.
[0034] Limiting blocks 5 are symmetrically arranged on the left and right sides of the roller assembly 3 to limit the position of the battery to be installed. When the battery 9 is placed on the roller assembly 3, the limiting blocks 5 can stabilize the battery 9 and prevent it from moving to the left or right.
[0035] refer to Figure 1 In an optional embodiment of this application, the roller assembly 3 consists of a housing, a roller, and a central shaft, with the central shaft passing through the roller and fixed inside the housing. When the housing is fixed, the roller will rotate along the central shaft under external force.
[0036] refer to Figure 1 , 2 In an optional embodiment of this application, the base plate 1 is provided with a mounting hole 12 for placing the roller assembly 3. The advantage is that the manufacturing cost is low, and the roller assembly 3 is self-positioned by fitting with the mounting hole 12 through its own structure. Thus, the roller assembly 3 will not be displaced when placed in the mounting hole 12, ensuring the stability of the battery 9 placed on the roller assembly 3.
[0037] refer to Figure 1 In an optional embodiment of this application, the limiting block 5 is offset from the mounting hole 12 from bottom to top. The greater the distance between the two opposing limiting blocks 5, the easier it is for the battery 9 to be placed on the roller assembly 3 from top to bottom. At this time, the limiting block 5 plays a guiding role.
[0038] refer to Figure 1 In this embodiment, the adjustment component can typically be a shim, a metal plate, etc. Although the height of the battery compartment varies between different vehicle models, the difference is not significant, falling within a few centimeters. For simplicity of overall structure and ease of operation, this embodiment generally uses a shim 4, and the inner hole size of the shim 4 is the same as the diameter of the mounting hole 12.
[0039] refer to Figure 1-2In an optional embodiment of this application, the base plate 1 is provided with a column 10 for placing the gaskets 4. Several gaskets 4 to be used are placed on the column 10 for easy handling. By increasing or decreasing the number of gaskets 4 between the roller assembly 3 and the base plate 1, the vertical height of the battery 9 can be quickly adjusted. When assembling the battery 9, the upper surface of the roller assembly of the battery assembly device needs to be slightly higher than the bottom height of the vehicle battery compartment 11. When removing the battery 9, the upper surface of the roller assembly 3 of the battery assembly device needs to be slightly lower than the bottom height of the vehicle battery compartment 11, which facilitates the movement of the battery 9 between the battery assembly device and the vehicle battery compartment 11. This structure achieves integrated assembly and disassembly tooling through gasket adjustment.
[0040] refer to Figure 1 In an optional embodiment of this application, to facilitate the battery assembly device in transporting the battery 9 to the required position, casters are fixedly installed at the bottom end of the base plate 1, and the casters are connected to the base plate by bolt fastening, facilitating subsequent replacement. To allow the battery assembly device to turn freely and make minor adjustments during pushing, the casters generally include front casters 6 and rear casters 7, with the front casters 6 being fixed wheels and the rear casters 7 being swivel wheels (e.g.,...). Figure 3 (As shown).
[0041] refer to Figure 1 In an optional embodiment of this application, a handle 2 is provided on the base plate 1 of the battery assembly device, and the handle 2 is composed of a side rod 21 and a pull rod 22. The height of the handle 2 conforms to ergonomics, making it convenient to push the battery assembly device.
[0042] refer to Figure 1 In an optional embodiment of this application, a rectangular steel pipe reinforcing rib 8 is provided at the lower end of the base plate 1 to ensure the reliable strength of the base plate 1.
[0043] The working process of the battery assembly device in this application is as follows:
[0044] When assembling battery 9, first remove the roller assembly 3 from the battery assembly device. Place a predetermined number of shims 4 according to the battery model. Note that the upper surface of the roller assembly of the battery assembly device should be slightly higher than the bottom of the battery compartment 11 in the vehicle body. This facilitates moving battery 9 from the battery assembly device to the battery compartment 11. Then, lower the roller assembly 3, and place any excess shims 4 onto the feed column 10. Manually use a crane with a chain hook to hoist battery 9 from top to bottom onto the battery assembly device. When battery 9 approaches the battery assembly device, slowly align it along the limit block 5 and place it on the roller assembly 3. Then, push the battery assembly device to the side of the vehicle body. At this point, the bottom of battery 9 on the battery assembly device should be slightly higher than the bottom of the battery compartment 11 in the vehicle body, facilitating manual pushing of battery 9 into the battery compartment 11. Move the battery assembly device to the side, and secure the battery 9 inside the vehicle body with the wiring connected. The entire assembly is now complete.
[0045] When removing battery 9, first take out the roller assembly 3 on the battery assembly device. According to the battery model, place a predetermined number of shims 4. Note that at this time, the height of the upper surface of the roller assembly of the battery assembly device needs to be slightly lower than the bottom height of the vehicle body battery compartment 11. This is to facilitate moving battery 9 from the vehicle body battery compartment 11 to the battery assembly device. Then, put down the roller assembly 3, and put the remaining shims 4 onto the material column 10. Manually pull battery 9 onto the roller assembly 3 inside the battery assembly device. Move the battery assembly device to the side, manually inspect battery 9 and maintain the vehicle body. After completion, reassemble battery 9.
