[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0034] Please refer to the attached document. Figures 1-3 A battery pack lifting hook device 100 is provided. The battery pack lifting hook device 100 is applied to the battery pack lifting equipment 200 and is used to position and support the battery pack 210.

[0035] Please refer to the attached document. Figures 1-3 In this embodiment of the application, the battery pack hook device 100 includes a hook body 10 and a support part 20; the hook body 10 and the support part 20 are two parts of the battery pack hook device 100. Optionally, the hook body 10 and the support part 20 can be an integrated structure or a detachable structure.

[0036] Furthermore, the support part 20 is disposed on the outside of the hook body 10, which is used to connect the lifting rope; the support part 20 and the hook body 10 form a limiting opening 20c; the limiting opening 20c serves as the space between the support part 20 and the hook body 10 and accommodates part of the battery pack lifting arm 210, so as to limit the battery pack lifting arm 210 in multiple directions. Thus, by limiting the battery pack lifting arm 210 in multiple directions through the support part 20 and the hook body 10, the stability of the battery pack lifting arm 210 during movement is ensured.

[0037] Meanwhile, the support part 20 is used to insert into the lifting hole of the battery pack. The part of the support part 20 located in the limiting opening 20c is used to support the lifting arm of the battery pack, so that the inner side wall of the limiting opening 20c restricts the position of the lifting arm of the battery pack. This ensures that the support part 21 and the hook body 10 limit the lifting arm 210 of the battery pack in different directions, avoids the battery pack tilting, and improves the lifting stability of the hook device 100 of the battery pack.

[0038] Please refer to the attached document. Figures 1-4 In this embodiment of the application, the hook body 10 serves as a supporting component of the hook device 100 of the battery pack. The hook body 10 is used to support the support part 20 and to connect the lifting rope, so that the hook device 100 of the battery pack can be connected to the lifting rope through the hook body 10, thereby facilitating the lifting rope to pull the battery pack 210 supported by the hook device 100 of the battery pack.

[0039] Please refer to the attached document. Figures 1-4 The hook body 10 is provided with a connecting hole 10a. The connecting hole 10a serves as the internal space of the hook body 10 and is used for connecting the lifting rope. This allows the hook body 10 to be connected to the lifting rope through the connecting hole 10a, thus facilitating the fixing of the lifting rope to the hook body 10. This, in turn, facilitates the lifting rope to lift the battery pack 210 during the pulling process via the hook body 10 and the support part 20. Optionally, the support part 20 can be elliptical, triangular, or square, and is not limited here. The support part 20 positions the lifting arm 211 of the battery pack 210.

[0040] Furthermore, the hook body 10 and the support part 20 are integrally connected, which improves the connection strength between the hook body 10 and the support part 20, ensures the connection effect between the hook body 10 and the support part 20, avoids the hook body 10 and the support part 20 from separating, and ensures the strength of the hook device 100 of the battery pack.

[0041] Please refer to the attached document. Figures 1-4In this embodiment, the support part 20 is disposed on the outside of the hook body 10; optionally, the support part 20 is located on the lower side of the hook body 10 and is arranged in the shape of a horizontal beam, while the hook body 10 can be arranged in the shape of a vertical beam.

[0042] Furthermore, the support part 20 and the hook body 10 form a limiting opening 20c; the limiting opening 20c serves as the space between the support part 20 and the hook body 10, and accommodates part of the battery pack lifting arm 210, so as to limit the battery pack lifting arm 210 in multiple directions. Thus, by limiting the battery pack lifting arm 210 in multiple directions through the support part 20 and the hook body 10, the stability of the battery pack lifting arm 210 during movement is ensured.

[0043] Meanwhile, the support part 20 is used to insert into the lifting hole of the battery pack. The part of the support part 20 located in the limiting opening 20c is used to support the lifting arm of the battery pack, so that the inner side wall of the limiting opening 20c restricts the position of the lifting arm of the battery pack. This ensures that the support part 21 and the hook body 10 limit the lifting arm 210 of the battery pack in different directions, avoids the battery pack tilting, and improves the lifting stability of the hook device 100 of the battery pack.

[0044] At this time, the support part 20 is provided with a groove 20a, which is recessed from top to bottom by the support part 20. The groove opening of the groove 20a faces upward. The groove 20a is used for the insertion of the lifting arm 211 of the battery pack, so that the groove 20a can be inserted into the lifting arm 211 of the battery pack through the groove opening of the groove 20a. This makes it easier for the groove 20a to limit the position of the lifting arm 211 and ensure the positional accuracy between the groove 20a and the battery pack 210. The support part 20 realizes the insertion of the lifting arm 211 of the battery pack through the groove 20a, so as to realize the support part 20 supporting the battery pack 210.

[0045] The groove 20a has two opposing inner sidewalls 20b, which are positioned on either side of the lifting arm 211. These inner sidewalls 20b respectively restrict the position of the lifting arm 211 on both sides, allowing the groove 20a to effectively limit the position of the lifting arm 211. The two inner sidewalls 20b also restrict the offset of the lifting arm 211 along the extension direction of the support 20, ensuring the position of the lifting arm 211 relative to the groove 20a and preventing it from detaching along the direction of the two inner sidewalls 20b of the groove 20a. Optionally, the lifting arm 211 may be restricted in the left-right or front-back direction to prevent it from detaching in either direction.

[0046] Please refer to the attached document. Figures 1-4In addition, the groove 20a is close to the connection between the support part 20 and the hook body 10 and is recessed downward along the surface of the support part 20 so that the inner sidewall 20b of the groove 20a is formed by the support part 20 and the hook body 10. This facilitates the combination of the support part 20 and the hook body 10 to restrict the position of the lifting arm 211, ensuring the position of the lifting arm 211 relative to the support part 20 and the hook body 10. This prevents the lifting arm 211 from leaving the position between the support part 20 and the hook body 10 during the lifting process, thus ensuring the lifting stability of the battery pack hook device 100.

[0047] Furthermore, the support portion 20 is arranged in an arc shape, and the groove 20a is arranged around the support portion 20 along the direction of the arc extension of the support portion 20, so that the inner contour of the groove 20a can be adapted to the inner contour of the lifting hole of the lifting arm 211, thus ensuring the stability of the insertion between the inner contour of the groove 20a and the inner contour of the through hole of the lifting arm 211.

[0048] In addition, there are multiple grooves 20a, which are arranged at intervals along the thickness of the hook body 10. When one groove 20a fails, the next groove 20a can continue to be used, which improves the life of the hook device of the battery pack.

[0049] Please refer to the attached document. Figures 1-4 The side wall of the hook body 10 facing the support 20 can abut against the outer side wall of the lifting arm 211 of the battery pack, and the bottom side wall of the groove 20a abuts against the lower side wall of the lifting arm 211 of the battery pack. This allows the hook body 10 and the bottom side wall of the groove 20a to abut against multiple side walls of the lifting arm 211 of the battery pack, thereby facilitating the restriction of multiple side walls of the lifting arm 211 and ensuring the positional accuracy of the lifting arm 211 of the battery pack relative to the support 20 and the hook body 10. Optionally, the width of the groove 20a is greater than the thickness of the lifting arm 211, thereby improving the insertion effect of the lifting arm 211 relative to the groove 20a and ensuring the connection efficiency between the lifting arm 211 and the support 20.

[0050] Please refer to the attached document. Figures 1-4 The angle between the support part 20 and the hook body 10 is α, 60≤α≤90, so that the support part 20 and the hook body 10 respectively abut against the two sides of the lifting arm 211. The hook body 10 is arranged in the vertical direction, and the support part 20 is arranged in the horizontal direction, so that the hook body 10 can extend upward when the support part 20 supports the lifting arm 211 of the battery pack, thereby making it easier for part of the hook body 10 to be higher than the lifting arm 211 of the battery pack, improving the connection convenience between the lifting rope and the hook body 10.

[0051] Work process: The support part 20 passes through the lifting hole of the lifting arm 211 of the battery pack 210 from the outside to the inside. The hook body 10 drives the groove 20a to lift upward. The lifting arm 211 is inserted into the groove 20a so that the outer surface of the hook body 10 and the bottom side wall of the groove 20a simultaneously abut against the lifting arm 211 of the battery pack 210. This allows the outer surface of the hook body 10 and the bottom side wall of the groove 20a to simultaneously support the battery pack 210, so that the hook body 10 and the support part 20 are combined and fixed to the lifting arm 211 of the battery pack 210. The lifting rope passes through the connecting hole 10a and is fixed to the hook body 10 so that the lifting rope can drive the battery pack 210 through the hook body 10 and the support part 20 during the lifting process.

[0052] Please refer to the attached document. Figures 5-7 In another embodiment, a battery pack hoisting device 200 includes a battery pack hook device 100 and a battery pack 210. The battery pack hook device 100 is connected to the battery pack 210 so that the battery pack hook device 100 is fixed to the battery pack 210. The battery pack hook device 100 is used to connect a hoisting rope, so that the hoisting rope can lift the battery pack 210 through the battery pack hook device 100 during the pulling process. The battery pack hook device 100 is part of the battery pack hoisting device 200, which is used to move the battery pack 210.

[0053] Please refer to the attached document. Figures 5-7 At this time, the battery pack hook device 100 includes a hook body 10 and a support part 20; the support part 20 is disposed on the outside of the hook body 10, and the hook body 10 is used to connect the lifting rope; the support part 20 and the hook body 10 surround to form a limiting opening 20c; the support part 20 is used to be inserted into the lifting hole of the battery pack, and the part of the support part 20 located in the limiting opening 20c is used to support the lifting arm of the battery pack, so that the inner sidewall of the limiting opening 20c restricts the position of the lifting arm of the battery pack, ensuring that the support part 21 and the hook body 10 limit the lifting arm 210 of the battery pack in different directions, avoiding the tilting of the battery pack, and improving the lifting stability of the battery pack hook device 100.

[0054] Work process: The support part 20 passes through the lifting hole of the lifting arm 211 of the battery pack 210 from the outside to the inside. The hook body 10 drives the groove 20a to lift upward. The lifting arm 211 is inserted into the groove 20a so that the outer surface of the hook body 10 and the bottom side wall of the groove 20a simultaneously abut against the lifting arm 211 of the battery pack 210. This allows the outer surface of the hook body 10 and the bottom side wall of the groove 20a to simultaneously support the battery pack 210, so that the hook body 10 and the support part 20 are combined and fixed to the lifting arm 211 of the battery pack 210. The lifting rope passes through the connecting hole 10a and is fixed to the hook body 10 so that the lifting rope can drive the battery pack 210 through the hook body 10 and the support part 20 during the lifting process.

[0055] The battery pack has multiple hook devices 100, which are spaced apart along the periphery of the battery pack 210. The multiple hook devices 100 are inserted into the lifting arm 211 of the battery pack 210 so that the lifting rope can lift the battery pack 210 through the multiple hook devices 100. By arranging multiple hook devices 100, the pulling stability of the lifting rope relative to the battery pack 210 is increased, thus ensuring the lifting effect of the battery pack 210.

[0056] Meanwhile, the limiting opening 20c serves as the space between the support part 20 and the hook body 10, and also accommodates part of the battery pack lifting arm 210, so as to limit the battery pack lifting arm 210 in multiple directions. Thus, by limiting the battery pack lifting arm 210 in multiple directions through the support part 20 and the hook body 10, the stability of the battery pack lifting arm 210 during movement is ensured.

[0057] The beneficial effects of this invention are as follows:

[0058] This utility model provides a hook device 100 and a lifting device 200 for a battery pack. The hook body 10 is used to connect a lifting rope. A support part 20 is disposed on one side of the hook body 10. The support part 20 and the hook body 10 surround and form a limiting opening 20c. The support part 20 is used to be inserted into the lifting hole of the battery pack. The part of the support part 20 located in the limiting opening 20c is used to support the lifting arm of the battery pack, so that the inner sidewall of the limiting opening 20c restricts the position of the lifting arm of the battery pack. This ensures that the support part 20 and the hook body 10 limit the lifting arm 210 of the battery pack in different directions, avoids the battery pack tilting, and improves the lifting stability of the hook device 100 for the battery pack.
