[0031] One of the core components of an electric vehicle is the power battery pack. During the production and manufacturing process of the battery pack, it is necessary to use a crane in cooperation with a lifting tool to lift and move the battery pack to achieve purposes such as transportation, transfer, and assembly. However, most of the existing lifting tools cannot be adjusted when fixing to the battery pack, so the existing lifting tools cannot cooperate with battery packs of different specifications to achieve lifting and moving.

[0032] Based on the above problems, the present disclosure provides an adjustable suspension assembly. By combining the mobile end of the suspension member in the positioning grooves at different positions, the suspension position of the suspension member on the connecting member is changed to meet the usage requirements of lifting and moving battery packs of different specifications, thereby improving the applicability.

[0033] Figure 1 Shown in the figure is a schematic diagram of the overall structure of the adjustable suspension assembly in an embodiment of the present disclosure. In Figure 1 the example, the adjustable suspension assembly includes a connecting member 10 and a suspension member 20. An adjustment groove 101 is formed on the connecting member 10; the adjustment groove 101 includes a guiding groove 1011 and at least two positioning grooves 1012 connected to the guiding groove 1011; each positioning groove 1012 corresponds to an adjustment position. The suspension member 20 has a mobile end 21; the mobile end 21 is movably disposed in the guiding groove 1011 and is adapted to be combined with one of the positioning grooves 1012 to adjust the suspension member 20 to the corresponding adjustment position.

[0034] Those skilled in the art can understand that by combining the mobile end 21 of the suspension member 20 in the positioning grooves 1012 at different positions, the suspension position of the suspension member 20 on the connecting member 10 is changed to meet the use requirements for lifting battery packs of different specifications, thereby improving the applicability.

[0035] In Figure 1 the example, the guiding groove 1011 is implemented to extend in the horizontal direction and is formed through the connecting member 10. The positioning grooves 1012 are implemented as two, and each end of the guiding groove 1011 in the length direction communicates with one of the positioning grooves 1012. Through the above settings, the horizontal suspension position of the suspension member 20 on the connecting member 10 can be changed. It is applicable to the situation where the battery pack to be lifted only changes in length and the height of the suspension position remains unchanged.

[0036] Exemplarily, the positioning groove 1012 is formed by extending downward from the bottom wall of the guiding groove 1011. In Figure 1 the example, the positioning groove 1012 is formed by extending vertically downward from the bottom wall of the guiding groove 1011. Preferably, the positioning groove 1012 is adapted to the size of the mobile end 21, and when the mobile end 21 is combined with the positioning groove 1012, the mobile end 21 does not protrude from the positioning groove 1012. For example, the width of the positioning groove 1012 is adapted to the size of the mobile end 21; the depth of the positioning groove 1012 is greater than the thickness of the mobile end 21. The advantage of such a setting is that it can avoid unnecessary horizontal movement of the mobile end 21 in the positioning groove 1012 during the process of lifting the battery pack, and at the same time avoid the situation where the mobile end 21 detaches from the positioning groove 1012 due to vertical movement.

[0037] Figure 2 Shown in the figure is a schematic diagram of another embodiment of the connecting member in an embodiment of the present disclosure. In Figure 2In the example, the positioning groove 1012A is formed by extending the bottom wall of the guide groove 1011A downwardly obliquely. By way of example, the two positioning grooves 1012A are inclined downwardly in the same or different directions. In the present embodiment, the two positioning grooves 1012A are inclined downwardly in the same direction. In this way, after the mobile end moves into the inclined positioning groove 1012A, the inclined inner wall on the upper side of the positioning groove 1012A will form a barrier to the movement of the mobile end in the vertical direction, thereby preventing the mobile end from moving redundantly in the vertical direction, and ensuring that the mobile end will not disengage from the positioning groove 1012A. In other embodiments, the two positioning grooves 1012A are inclined downwardly in different directions.

[0038] Figure 3 FIG. 1 is a schematic structural diagram of another embodiment of the connector 10 in the present disclosure. Figure 3 In the example, the guide groove 1011B is implemented to extend along an inclined direction and is formed through the connector 10. That is, the guide groove 1011B has a high end and a low end. The positioning groove 1012B is implemented as two, and the high end and the low end of the guide groove 1011B are each connected to a positioning groove 1012B. Those skilled in the art will understand that, through the above-mentioned arrangement, it is possible to change the horizontal suspension position of the suspension member on the connector 10, and at the same time, it is possible to change the suspension position of the suspension member at different heights on the connector 10. It is suitable for situations where the length of the battery pack being moved has changed and the height of the suspension position of the battery pack has changed, which further improves the use effect of the adjustable suspension member 20.

[0039] When the suspension members are implemented as a pair, the operator can change the installation direction of the pair of connectors 10 so that the high ends of the pair of guide grooves 1011B face each other, so that the distance between the pair of suspension members is the largest when they are in the positioning grooves 1012B at the lower end, and the distance between them is the smallest when they are in the positioning grooves 1012B at the higher end. When the lower ends of the pair of guide grooves 1011B face each other, the adjustment result is opposite to the above.

[0040] In the above embodiment, a rubber pad (not shown in the figure) is provided on the bottom wall of the positioning groove to reduce the degree of wear of the moving end and the positioning groove during the lifting and moving process, thereby increasing the overall life of the adjustable suspension assembly.

[0041] Figure 4 The figure shows a cross-sectional view of the overall structure of the adjustable suspension assembly in the embodiment of the present disclosure. Figure 1 and Figure 4In the example, the suspension member 20 includes an adjustable-length suspension piece 22, a rotating piece 23, and a clamping piece 24; the first end of the suspension piece 22 is implemented as the mobile end 21; one end of the rotating piece 23 is hinged to the top of the clamping piece 24, and the other end is connected to the second end of the suspension piece 22. Those skilled in the art can understand that the length of the suspension assembly is adjustable, and it can lift and move battery packs at different heights, further improving the applicability of this application.

[0042] Exemplarily, the suspension piece 22 includes at least one or more sequentially connected suspension rings 221. In this embodiment, the suspension ring 221 is implemented as one. The top end of the one suspension ring 221 is implemented as the first end, and the bottom end of the one suspension ring 221 is implemented as the second end. Further exemplarily, the suspension ring 221 has a notch, and a blocking cylinder that can block the notch is threadedly connected to the suspension ring 221. Those skilled in the art can understand that by changing the position of the blocking cylinder, the suspension ring 221 can be removed to replace the suspension ring 221 with a different length, thereby adjusting the length of the suspension piece 22. At the same time, the suspension ring 221 with a notch can be connected to the rotating piece 23.

[0043] In Figure 1 and Figure 4 the example, the clamping piece 24 includes a clamping frame 241 with an opening and a fixing rod 242. The top end of the clamping frame 241 is hinged to the rotating piece 23. The fixing rod 242 is movably connected to the clamping frame 241 in the vertical direction. It can be understood that the setting of the rotating piece 23 enables the operator to change the orientation of the opening of the clamping piece 24, so as to change the clamping direction and position of the clamping piece 24 and improve the clamping effect of the clamping piece 24.

[0044] In this embodiment, a support plate 243 is provided inside the opening of the clamping frame 241, and the fixing rod 242 is slidably combined with the support plate 243 in the vertical direction. In this way, after the battery pack is located in the space between the support plate 243 and the bottom end of the clamping frame 241, the fixing rod 242 slides downward until one end passes through the support plate 243 and is inserted into the hole on the end face of the battery pack to form a snap fit. Those skilled in the art can understand that the fixing rod 242 can also be directly slidably combined with the top end of the clamping frame 241 in the vertical direction. The fixing rod 242 is threadedly connected to the support plate 243 in the vertical direction.

[0045] Exemplarily, a protective pad 2411 is installed on the inner wall of the opening of the clamping frame 241. To avoid the situation that the battery pack is bruised due to contact with the inner wall of the clamping frame 241.

[0046] In another embodiment, the suspension member 22 includes a plurality of suspension rings 221 connected in sequence. In this way, the length of the suspension member 22 can be adjusted by changing the number of the suspension rings 221.

[0047] In another embodiment, the suspension assembly may only include the suspension member 22 and the clamping member 24, and the suspension member 22 is directly connected to the clamping member 24, without having to provide the rotating member 23.

[0048] In still another embodiment of the present disclosure, a battery pack lifting tool is provided, including a lifting tool main body and a plurality of the adjustable suspension assemblies; the plurality of adjustable suspension assemblies are detachably connected to different positions of the lifting tool main body. Exemplarily, the connecting member 10 is bolted to the lifting tool main body.

[0049] In summary, the embodiments of the present disclosure provide an adjustable suspension assembly and a battery pack lifting tool thereof. The adjustable suspension assembly includes: a connecting member formed with an adjustment groove; the adjustment groove includes a guiding groove and at least two positioning grooves connected to the guiding groove; each positioning groove corresponds to an adjustment position; a suspension member having a mobile end; the mobile end is movably disposed in the guiding groove and is adapted to be combined with one of the positioning grooves to adjust the suspension member to the corresponding adjustment position.
