Description

Technical Field

[0001] This utility model belongs to the field of battery box, and specifically relates to a detachable lifting lug. Background Technology

[0002] Depending on the vehicle model, the types and appearances of battery packs for new energy vehicles vary widely. Detachable hangers, serving as a crucial structural link between the battery system and the vehicle, are a vital component. The diverse sizes and quantities of battery boxes have driven the development of hanger structures towards greater flexibility and adjustability. Current battery boxes are typically made of pure aluminum or steel, with hangers and frames (transfer beams) mostly connected as a single piece or using sheet metal stamping and welding processes. These are not detachable, and damage to the box or hangers often results in the entire battery pack being scrapped, leading to significant losses. Furthermore, welding generates substantial deformation, involves complex processes, and requires high precision in the flatness and position of the battery swapping mechanism, making it difficult to meet these requirements.

[0032] The main body 20 of the lifting lug is detachably mounted on the adapter assembly, which is used to connect to the frame 10 of the battery box.

[0033] In this embodiment, the lifting lug body 20 is detachably mounted on the frame 10 of the battery box via the adapter assembly. A schematic diagram after installation is shown below. Figure 1 As shown;

[0034] The adapter component reduces the stress on the frame 10 when the lug body 20 is directly detached and installed on the frame 10, thereby improving the safety of the battery pack.

[0035] In some embodiments of this utility model, the adapter assembly includes an adapter beam 40;

[0036] The lug body 20 is detachably mounted on the side wall of the adapter beam 40, and the side wall of the adapter beam 40 opposite to the lug body 20 is connected to the frame 10.

[0037] In this embodiment, by setting the adapter beam 40, the stress on the frame 10 when the main body of the lifting lug 20 is directly detached and installed on the frame 10 is reduced, which facilitates disassembly, repair and replacement of the lifting lug, and reduces the deformation generated during the detachable installation process.

[0038] In some embodiments of this utility model, the adapter assembly further includes an adapter plate 30;

[0039] The adapter beam 40 is provided with adapter plates 30 at both ends. The adapter plates 30 are located between the adapter beam 40 and the frame 10. The length of the adapter plates 30 is less than half the length of the adapter beam 40.

[0040] In this embodiment, by setting the adapter plate 30, the stress on both ends of the frame 10 is further reduced when the adapter beam 40 is directly installed with the frame 10, thereby further improving the safety of the battery pack.
