[0035] a body 100;

[0036] a first limiting structure 200 provided on the body 100;

[0037] a second limiting structure 300 movably provided on the body 100 and having a locking position and a loosening position, and when the second limiting structure 300 is in the locking position, the first limiting structure 200 and the second limiting structure 300 can clamp the battery cell module 600, and when the second limiting structure 300 is in the loosening position, the second limiting structure 300 is separated from the battery cell module 600;

[0038] a resilient structure 400 provided between the second limiting structure 300 and the body 100; when the second limiting structure 300 is moved towards the loosening position under the action of an external force, the resilient structure 400 deforms; when the external force acting on the second limiting structure 300 is removed, the resilient structure 400 drives the second limiting structure 300 to move and remain in the locking position. Compared with the prior art, by providing the resilient structure 400 between the body 100 and the second limiting structure 300, the second limiting structure 300 can be automatically locked under the action of the resilient structure 400, which not only effectively simplifies the structure, but also improves the convenience and efficiency of operation.

[0039] Specifically, as Figures 1 to 6 shown in the embodiment, the battery cell module lifting device mainly comprises a clamping assembly and a lifting frame 800, wherein the clamping assembly is used to fix the battery cell module 600, and the lifting frame 800 is connected with the clamping assembly and moves the battery cell module 600 into the battery shell through the clamping assembly.

[0040] In the embodiment, at least one set of corresponding first positioning holes 610 and second positioning holes 620 are respectively arranged on the left and right sides of the battery cell module 600, wherein the first positioning holes 610 extend from top to bottom, the second positioning holes 620 extend from bottom to top, and the first positioning holes 610 and the second positioning holes 620 are coaxial and communicate. This design enables the clamping assembly to clamp the battery cell module 600 from the side, realizes a double limiting function, and ensures the stability of clamping.

[0041] Preferably, in the embodiment, two sets of corresponding first positioning holes 610 and second positioning holes 620 are respectively arranged on the left and right sides of the battery cell module 600, so that the battery cell module 600 forms four clamping positions, further improving the stability and safety of clamping and lifting the battery cell module 600.

[0042] In the embodiment, the battery cell module 600 is further provided with a second movable slot 630.

The first limiting structure 200 can be clamped into or out of the first positioning hole 610 through the second movable slot 630. Preferably, the size of the second movable slot 630 is larger than that of the first limiting structure 200. This design ensures that the first limiting structure 200 can be smoothly clamped into or out of the first positioning hole 610 from the side. Compared with the conventional design of clamping into the first positioning hole 610 from the bottom of the battery cell module 600, the volume of the clamping assembly is effectively reduced.

[0043] Preferably, in the embodiment, the second movable slot 630 is provided with a plurality of slots and corresponds to the first positioning hole 610 one by one.

[0044] In the embodiment, the clamping assembly includes a body 100 and a first limiting structure 200 and a second limiting structure 300 arranged on the body 100. The first limiting structure 200 and the second limiting structure 300 are arranged in an upper and lower structure and cooperatively form a C-shaped clamping gap to form a clamping space. When the second limiting structure 300 moves between the locked position and the relaxed position, the size of the clamping gap can be adjusted. This design enables the clamping structure to clamp different specifications of battery cell modules 600.

[0045] Preferably, in the embodiment, the first limiting structure 200 is arranged below the second limiting structure 300 as a fixed structure. This design avoids the gravity of the battery cell module 600 acting on the movable second limiting structure 300, thereby avoiding the failure of the elastic structure 400 and effectively ensuring the stability of the clamping.

[0046] In the embodiment, the body 100 is arranged vertically, and the first limiting structure 200 is arranged at the lower end of the body 100. One side of the first limiting structure 200 is vertically connected to the body 100, and the other side extends away from the body 100 and has a vertically upward protrusion 210.

Preferably, the first limiting structure 200 and the body 100 are integrally formed to effectively ensure the strength of the first limiting structure 200.

[0047] In the embodiment, the second limiting structure 300 is movably connected to the upper end of the body 100 in the vertical direction, and has a locking position and a loosening position; when the battery cell module 600 is located in the clamping gap, and the second limiting structure 300 is in the locking position, the first limiting structure 200 is clamped into the first positioning hole 610, and the second limiting structure 300 is clamped into the second positioning hole 620, so that the clamping of the battery cell module 600 is achieved. It is worth noting that when the first limiting structure 200 and the second limiting structure 300 are clamped into the first positioning hole 610 and the second positioning hole 620 respectively, the movement of the battery cell module 600 on the clamping assembly can be limited, and the phenomenon that the battery cell module 600 is loose or falls off during hoisting can be effectively avoided.

[0048] Preferably, in the embodiment, the second limiting structure 300 is in the shape of a cylinder, and a reinforcing portion 310 in the shape of a circular block coaxial with the second limiting structure 300 is arranged at one end of the second limiting structure 300 close to the first limiting structure 200; when the second limiting structure 300 is in the locking position, the reinforcing portion 310 abuts against the outer wall of the battery cell module 600. The contact area between the second limiting structure 300 and the battery cell module 600 is enlarged through the reinforcing portion 310, so that the stability of clamping is improved.

That is, the operator can pull the adjusting piece 500 to drive the second limiting structure 300 to move towards the loosening position. By taking the adjusting piece 500 as an intermediary for transmitting the external force, a clear force application point is provided for the operator, which not only facilitates the operator to apply force accurately, but also significantly improves the convenience of movement of the second limiting structure 300.

[0050] In the embodiment, the adjusting piece 500 includes a connecting portion 510 and an adjusting portion 520, wherein the connecting portion 510 is detachably connected to the second limiting structure 300, and the adjusting portion 520 is connected to one end of the connecting portion 510 and extends horizontally away from the second limiting structure 300 at the other end. This design improves the convenience of disassembly and maintenance of the adjusting piece 500, and improves the convenience of operation.

[0051] Preferably, in the embodiment, the connecting portion 510 is in the shape of a nut and is threadedly connected to the second limiting structure 300, the adjusting portion 520 is in the shape of a cylinder, and the connecting portion 510 and the adjusting portion 520 are integrally formed. This design ensures the strength of the adjusting piece 500.

[0052] The manual locking mode in the prior art leads to complex overall structure and cumbersome operation, therefore, the utility model discloses a spring structure 400 is arranged between the second limiting structure 300 and the body 100, and the automatic locking of the second limiting structure 300 is realized by the elastic deformation capacity of the spring structure 400, which not only simplifies the structure of the clamping assembly, but also saves the operation process.

[0053] In the embodiment, the spring structure 400 is vertically arranged, one end of which abuts against the body 100, and the other end of which abuts against the adjusting piece 500; when the adjusting piece 500 is driven by external force to move the second limiting structure 300 towards the loosening position, the spring structure 400 can be compressed and deformed upwards; when the external force acting on the adjusting piece 500 is removed, the spring structure 400 extends downwards by its elastic force, drives the adjusting piece 500 to move and keep the second limiting structure 300 in the locking position. The design effectively reduces the occupation of the horizontal space, improves the compactness of the structure; and since the extending direction of the spring structure 400 is consistent with the direction of gravity, the stability of the locking of the second limiting structure 300 can be further ensured.

[0054] In the embodiment, the body 100 is further provided with a first guide hole 110 and a second guide hole 120 which are coaxial and communicate with each other, one end of the spring structure 400 is fixedly arranged in the first guide hole 110, the other end abuts against the connecting part 510 of the adjusting piece 500, the second limiting structure 300 is movably arranged in the second guide hole 120, the inner diameter of the first guide hole 110 is adapted to the outer diameter of the spring structure 400, and the inner diameter of the second guide hole 120 is adapted to the outer diameter of the second limiting structure 300.

[0055] Preferably, in the embodiment, the first guide hole 110 is above the second guide hole 120, and the diameter of the second guide hole 120 is smaller than the diameter of the connecting part 510. The design makes the adjusting piece 500 clamped above the second guide hole 120, so that the second limiting structure 300 connected with the adjusting piece 500 is prevented from falling off from the body 100 in the non-working state.

[0056] In the embodiment, the body 100 is further provided with a first movable slot 130, which is located between the first guide hole 110 and the second guide hole 120 and communicates with the first guide hole 110 and the second guide hole 120. The adjusting member 500 is movably horizontally extended into the first movable slot 130, and the first movable slot 130 can limit the moving stroke of the adjusting member 500. The design of the first movable slot 130 can not only control the moving range of the adjusting member 500, improve the stability and the safety of operation, but also improve the convenience of moving and disassembling the adjusting member 500.

[0057] Preferably, the first movable slot 130 extends along the length direction of the body 100 and is provided with three openings communicating with the outside. The adjusting part 520 is movably arranged in one of the openings.

[0058] In the embodiment, the clamping assembly clamps the battery cell module 600 in the following way.

[0059] In the embodiment, the clamping assembly clamps the battery cell module 600 in the following way. The operator first pulls up the adjusting part 520 to make the second limiting structure 300 exit from the second positioning hole 620, then moves the body 100 downward, moves the body 100 horizontally to make the first limiting structure 200 exit from the first limiting hole, and finally releases the adjusting part 520, thereby unloading the battery cell module 600.

[0060] In the embodiment, the top end of the body 100 is detachably provided with a lifting ring 700.
