The sliding groove 4 is formed on the fixing plate 102, and one end of the second connecting plate 103 is located within the sliding groove 4. The second connecting plate 103 is connected to the fixing plate 102 by bolts. The sliding groove 4 on the fixing plate 102 allows for flexible adjustment and positioning according to the size of the battery pack. Adjusting the distance between the left and right second connecting plates 103 changes the distance between the left and right sides and the lifting points of the battery pack. After adjustment, the second connecting plate 103 is fixed. One lifting device can lift battery packs of multiple sizes, making it convenient to use.

[0019] The battery lifting device structure 3 includes a first connecting chain 301 and a first lifting plate 302. One end of the first connecting chain 301 is connected to the fixed plate 102. The two ends of the first lifting plate 302 are connected to second lifting plates 303. The other end of the first connecting chain 301 is connected to the second lifting plate 303. A first locking pin 304 is connected to the first lifting plate 302, and a second locking pin 305 is connected to the second lifting plate 303. Four first connecting chains 301 are symmetrically arranged on the fixed plate 102. Each first connecting chain 301 connects to a second hanging plate 303, thus integrally connecting the first and second hanging plates 302 and 303. A second locking pin 305 is connected to the second hanging plate 303 located at the bottom. During battery pack hoisting, the second locking pin 305 passes through holes in the second hanging plate 303 and the battery pack housing, connecting the second hanging plate 303 and the battery pack housing to secure it.

The first connecting chain 301 is connected to the connecting lug 9 to fix the first connecting chain 301.

[0024] The battery lifting structure 3 is symmetrically arranged with respect to the central axis of the fixing plate 102. The symmetrical arrangement of the battery lifting structure 3, fixed at the corners of the battery pack, provides more stable fixation of the battery pack.

[0025] The second connecting plate 103 is provided with a connecting pin 104, which is connected to the first connecting chain 301. The second connecting plate 103 is connected to the connecting pin 104, and the first connecting chain 301 is connected to the second connecting plate 103 through the connecting pin 104. The first connecting chain 301 is fixed at both ends of the two second connecting plates 103. The two second connecting plates 103 form a total of four lifting points, which can ensure the stability of the battery pack during the lifting process and prevent it from shaking.

[0026] During battery pack hoisting, the second locking pin 305 passes through the holes in the second lifting plate 303 and the battery pack housing, connecting the second lifting plate 303 and the battery pack housing to secure the battery pack housing. The first locking pin 304 passes through the first lifting plate 302, and during battery pack hoisting, the first locking pin 304 abuts against the battery pack housing to prevent the battery pack from swaying to the side, thus preventing instability. Through the combined action of the first locking pin 304 and the second locking pin 305, the battery pack can be secured during hoisting, preventing it from swaying. After hoisting, the battery pack can be removed.
