[0002] In order to obtain a high-voltage, high-capacity power supply platform, multiple battery cells are generally connected in series and parallel to form a battery module to supply power to the outside. The process of assembling multiple battery cells into a battery module through a bus, foam, double-sided tape, a sampling circuit board, etc. is called PACK. PACK first stacks multiple battery cells into a battery pack in a certain direction, sets foam between the battery cells, and adheres them together with double-sided tape, and then bundles them with tape or PET tape, and then welds the bus and sampling circuit board, etc., and finally puts them into the box to complete. Before the PACK process, the battery cells need to be transported and placed in a designated position. During the PACK process, the stacked battery modules need to be transported between multiple stations, and the stacking state of the battery pack needs to be ensured during the transportation process. In the related art, when the traditional hoist is used to hoist the battery pack and battery module, the clamping force is uneven, which easily causes multiple battery cells to be misaligned.

[0010] In one embodiment, the support member is located at the end of the clamp arm, the second drive member is connected between the support member and the clamp arm, and in the radial direction, the second drive member is located inside the area surrounded by the outer circumference of the clamp arm.

[0030] Refer to Figure 1, which shows a schematic structural diagram of a battery hanger unit in an embodiment of the present application. The hanger unit 10 provided in an embodiment of the present application includes a clamping assembly 100 and a driving assembly 200. The clamping assembly 100 includes at least two relatively arranged clamping arms 110 and a support member 120 arranged on the clamping arms 110, wherein the clamping arms 110 are used to clamp the battery 2, and the support member 120 is used to support the clamped battery 2; and the driving assembly 200 is connected to the clamping assembly 100, wherein the driving assembly 200 is used to drive the clamping arms 110 to move relative to the battery 2 to clamp or release the battery 2, or the driving assembly 200 is used to drive the support member 120 to move relative to the clamping arms 110 to support the battery 2.

[0031] The above-mentioned sling unit 10 can adjust the degree of clamping by the movement of the clamp arm 110 while clamping the battery, so as to maintain the degree of clamping the battery during transportation. The support member 120 of the above-mentioned sling unit 10 can support the battery, and by driving, the support member 120 can provide a supporting function when needed without hindering the clamping of the battery.

[0032] Furthermore, each sling unit 10 is used to clamp the battery cell 2. In combination with FIG. 2 , FIG. 2 shows a schematic diagram of the structure of a battery sling device 1 in an embodiment of the present application. In some embodiments, the sling device 1 includes at least two battery sling units 10 as described above and a sling plate 20, the sling plate 20 is connected to the battery sling unit 10, and the sling plate 20 is used to fix the adjacent battery sling units 10. The sling device 1 is used to clamp a battery pack formed by stacking battery cells 2, and the arrangement of each battery sling unit 10 corresponds one-to-one to the arrangement of each battery cell 2.

[0033] By setting up the lifting device 1, each battery cell 2 in the battery pack is equipped with a battery lifting unit 10 during the lifting and transportation process. Each battery cell 2 is subjected to uniform force, thereby maintaining the stacking state of the battery pack. This solves the problem of inconsistent force on the battery during the transportation of the battery pack, which causes relative displacement of the battery cell 2 under the action of its gravity, thereby avoiding affecting the subsequent assembly and use of the battery pack. At the same time, the arrangement of the battery lifting unit 10 is fixed by the lifting plate 20, so that the lifting device is more adapted to the battery stacking method, thereby improving the stability of lifting and transportation.

[0034] In one embodiment, the driving assembly 200 includes a first driving member 210 , which is disposed at one end of the clamp arm 110 away from the support member 120 , and the first driving member 210 is used to drive the clamp arm 110 to move closer to or away from the battery.

[0035] Specifically, in the embodiment shown in FIG. 1 , the battery cell 2 is a square battery, and two clamp arms 110 are provided, and each clamp arm 110 can be clamped on two parallel sides of the battery cell 2. The clamp arm 110 includes a first end 101 and a second end 102, and the first end 101 and the second end 102 are two ends of the clamp arm that are away from each other in the first direction X. A transmission plate 300 is provided at the first end 101 of each clamp arm 110, and the clamp arm 110 is connected to the first driving member 210 through the transmission plate 300. The clamp arm 110 is movably connected to the transmission plate 300. Under the action of the first driving member 210, the clamp arms 110 are moved closer to or away from the transmission plate 300, and the transmission plate 300 also plays a role in supporting the first driving member 210.

[0036] The clamping arms 110 are extended along a first direction X, and the first direction X is parallel to the clamped surface of the battery cell 2. The clamping arms 110 have an initial state and a clamping state. In the initial state, the distance between adjacent clamping arms 110 is greater than the outer diameter of the battery cell 2, forming a channel for the battery to enter. As the clamping arms 110 move, the clamping arms 110 gradually change from the initial state to the clamping state, and the distance between adjacent clamping arms 110 is equal to the outer diameter of the battery cell 2, forming a clamping channel for clamping the battery. The clamping arms 110 can also move further to clamp the battery cell 2.

[0037] The clamp arm 110 includes a vertical arm 112 and a horizontal arm 111. The vertical arm 112 and the horizontal arm 111 are arranged vertically, so that the clamp arm 110 is L-shaped as a whole. The vertical arm 112 is extended along the first direction X, and the length of the vertical arm 112 is greater than or slightly greater than the height of the battery cell 2. The horizontal arm 111 is movably connected to the transmission plate 300 and is located on the side of the transmission plate 300 away from the first driving member 210. After clamping, the horizontal arm 111 is located on the top of the battery. When two clamp arms 110 are arranged opposite to each other, the length of the horizontal arm 111 does not exceed one-half of the horizontal width of the battery, so as to provide a sufficient distance for the clamp arm 110 to move.

[0038] The hoisting plate 20 is connected to the side of the first driving member 210 away from the clamping arm 110. A plurality of mounting positions are provided on the hoisting plate 20, each mounting position corresponding to a battery hoist unit 10, and the first driving member 210 of the battery hoist unit 10 is detachably connected to the hoisting plate 20 to enable the battery hoist unit 10 to adjust its position according to requirements (battery cell 2 size, stacking condition, etc.). The distance between the mounting positions matches the spacing between the battery cells 2. In other embodiments, each hoisting device 1 may be provided with at least one first driving member 210, and one driving member may drive the clamping arms 110 of multiple battery hoist units 10 to move synchronously, which is suitable for stacked battery packs with uniform force shapes such as squares.

[0039] In one embodiment, the driving assembly 200 includes a second driving member 220, which is disposed between the clamp arm 110 and the support member 120. The support member 120 includes a supporting state and an idle state. The second driving member 220 is used to drive the support member 120 to move relative to the clamp arm 110 to switch between the supporting state and the idle state. The support member 120 can support the battery in the supporting state.

[0040] Specifically, the support member 120 is disposed at the second end 102 of the clamp arm 110 , and the support arm is plate-shaped or rod-shaped, and the support arm matches the shape of the bottom surface of the battery cell 2 . The second driving member 220 is connected between the support member 120 and the clamp arm 110 .

[0041] In the radial direction, the second driving member 220 is located inside the area surrounded by the outer circumference of the clamping arm 110, that is, the outer surface of the second driving member 220 does not protrude from the outer circumference of the clamping arm 110 to prevent the battery cell 2 to be clamped from entering the clamping channel.

[0042] In one embodiment, a clamping channel having the same outer diameter as the battery is defined between at least two of the clamping arms 110 , and when the support member 120 is in an idle state, an edge of the support member 120 on each clamping arm 110 does not exceed an edge of the clamping channel.

[0043] In one embodiment, the second driving member 220 is used to drive the support member 120 to rotate around the clamping arm 110 at a preset angle; when the support member 120 is in a supporting state, the support member 120 is vertically arranged with the clamping arm 110; when the support member 120 is in an idle state, the support member 120 is vertically arranged with the clamping arm 110 and the orientation of the support member 120 is different from that in the supporting state, or the support member 120 is parallelly arranged with the clamping arm 110.

[0044] When the support member 120 is in the supporting state, the support member 120 is arranged perpendicularly to the clamping arm 110 to match the shape of the square battery cell 2, and the support member 120 supports the bottom surface of the battery cell 2. When the support member 120 is in the idle state, the support member 120 is arranged perpendicularly to the clamping arm 110 and the orientation of the support member 120 is different from that in the supporting state. The support member 120 can move to the area where the non-clamping channel is located to prevent the clamping of the battery from being affected, for example, the support member 120 is facing the adjacent battery hanger unit 10, or the support member 120 is facing away from the battery cell 2; or, when the support member 120 is in the idle state, the support member 120 is arranged parallel to the clamping arm 110, and the support member 120 is folded and stored at one side of the clamping arm 110.

[0045] In one of the embodiments, when the support member 120 is in an idle state, the support member 120 on one of the clamping arms 110 and the support member 120 on the other clamping arm 110 rotate at the same angle to switch from the idle state to the supporting state.

[0046] The support member 120 on one of the clamping arms 110 and the support member 120 on the other clamping arm 110 rotate in the same direction and at the same angle to switch from the idle state to the supporting state. Specifically, as an implementation method, in the embodiment shown in the figure, the support member 120 is in the idle state, the support member 120 provided on one clamping arm 110 is arranged toward the second direction Y, and the support member 120 provided on the other clamping arm 110 is arranged toward a direction parallel to and opposite to the second direction Y, and the second direction Y is perpendicular to the first direction X. When switching to the supporting state, the second driving member 220 drives the two support members 120 to rotate 90° in the clockwise direction, so as to achieve a relative arrangement and perpendicular to the first direction X.

[0047] In one embodiment, when the support member 120 is in the supporting state, the center lines of the two opposing support members 120 do not overlap. As shown in FIG3 , the support member 120 includes a main body 121 and a widening portion 122. When the support member 120 is in the supporting state, the main bodies 121 of the two opposing support members 120 are symmetrically arranged, that is, the center lines of the main bodies 121 of the two opposing support members 120 overlap, and the widening portions 122 of the two opposing support members 120 are diagonally arranged, that is, the widening portions 122 of the two opposing support members 120 are arranged on different sides of the main body 121. In combination with the fact that the support member 120 can rotate in the same direction and at the same angle to reach the supporting state, the diagonal arrangement of the widening portion 122 is on the side of the main body 121 away from the rotation direction, which can prevent the support member 120 from affecting the battery entry channel in the vacant state, and can also enhance the supporting strength of the support member 120. Further, the width of the support member 120 is greater than 50% of the width of the bottom surface of the battery cell 2.

[0048] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0049] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
