[0042] Based on the research on the above problems, an embodiment of the present invention provides a hanging lug solution to improve the above problems.

[0043] See also Figure 1 , Figure 1A battery pack 20 is shown, which includes a battery pack body 60 and a lifting lug device 10. The lifting lug device 10 can be provided on any side of the battery pack body 60.

[0044] Please refer to Figure 2 In this embodiment, the lifting ear device 10 includes a base 11 and a sliding lifting ear assembly 12.

[0045] The base 11 is mounted on the battery pack 20 , and the sliding ear assembly 12 is slidably mounted on the base 11 . The sliding ear assembly 12 can change its position by sliding.

[0046] Before the battery pack 20 is installed and fixed, the installation position of the base 11 and the number of sliding ear assemblies 12 used can be adjusted according to actual conditions.

[0047] In one possible implementation, continue to refer to Figure 2 At least one fixing screw hole 40 can be set on any side or any multiple side surfaces of the battery pack body 60. When the installation position of the base 11 is determined, it can be fixed with screws or the like through the fixing screw hole 40 at that position, thereby achieving adjustable installation position of the base 11.

[0048] In another possible implementation, a chute can be provided on the base 11, and the sliding lug assembly 12 can be inserted into the chute and mounted on the base 11, and the chute can be used to slide the sliding lug assembly 12. When only one sliding lug assembly 12 is required, the sliding lug assembly 12 can be directly inserted into the chute; when two or more sliding lug assemblies 12 are required, each sliding lug assembly 12 can be inserted into the chute sequentially, thereby achieving an adjustable number of sliding lug assemblies 12 to be used.

[0049] Based on this structural setting, the sliding ear assembly 12 can adjust its own installation position through the installation position of the base 11 and the sliding of the sliding ear assembly 12.

[0050] The shape of the battery pack body 60 provided in this embodiment is not limited, for example, it can be a cuboid, a cube, a prism, etc. The ear device 10 is mounted on the surface of the battery pack body 60 through the base 11.

[0051] In this embodiment, the base 11 can be flexibly selected as long as it can be mounted on the surface of the battery pack 20 and allows the sliding lug assembly 12 to be slidably mounted. In one possible implementation, the base 11 can be a carrier plate that fits over a large area of ​​the battery pack 20 surface and has a slot defined therein into which the sliding lug assembly 12 is inserted. The sliding lug assembly 12 adjusts its position by sliding within the slot.

[0052] The hanging ear device 10 provided in this embodiment installs the base 11 on the battery pack 20, and then adjusts the actual installation position of the sliding hanging ear assembly 12 by sliding, thereby realizing variable installation of the sliding hanging ear assembly 12, improving the flexibility and versatility of the hanging ear device, and meeting the needs of more application scenarios.

[0053] In order to further ensure the stability and safety of the battery pack 20 during use and improve the versatility of the ear device 10, please refer to Figure 3 A plurality of fixing screw holes 40 are provided on the surface of the battery pack 20 , and the base 11 includes a mounting clip 111 and a first supporting plate 112 .

[0054] The mounting clip 111 is welded around the first carrier plate 112. The mounting clip 111 has screw holes with the same shape and size as the fixing screw holes 40. The fixing bolts 30 are connected to the fixing screw holes 40 through the screw holes on the mounting clip 111, thereby mounting the base 11 on the battery pack 20.

[0055] The mounting position of the base 11 is adjustable. For example, the battery pack 20 provided in this embodiment has multiple fixing screw holes 40 on its surface. The fixing bolts 30 are secured in the fixing screw holes 40 through the screw holes on the mounting clips 111. Before the battery pack 20 is installed and secured, the fixing screw holes 40 on the surface of the battery pack 20 corresponding to the mounting clips 111 can be adjusted to adjust the mounting position of the mounting clips 111 according to actual conditions, thereby achieving adjustable installation of the base 11. Based on this structural arrangement, the mounting position of the sliding ear assembly 12 can be indirectly adjusted through the mounting position of the base 11.

[0056] Furthermore, in order to prevent the battery pack 20 from accidentally shifting and falling off, in this embodiment, the outer shell and base 11 of the battery pack 20 are made of magnetic material. The base 11 is installed on the battery pack 20 by fixing bolts 30 and can be further fixed by magnetic force.

[0057] In order to further realize the sliding effect of the sliding ear assembly 12, please refer to Figure 4 The first supporting plate 112 is provided with a plurality of sliding grooves 1121 of the same shape and size.

[0058] The shape of the slide groove 1121 provided in this embodiment is not limited; for example, it can be T-shaped, V-shaped, or cross-shaped. The sliding ear assembly 12 can be slidably mounted within and slide along the slide groove 1121. For ease of demonstration, this embodiment uses a cross-shaped slide groove. Each slide groove 1121 is distributed parallel to the surface of the first supporting plate 112. In addition, multiple fixing screw holes 40 are drilled on the side of the slide groove 1121 near the surface of the battery pack 20. The screw holes are horizontally distributed within the slide groove 1121.

[0059] Please refer to Figure 5 The sliding ear assembly 12 includes a plurality of first sliders 121 , a second bearing plate 122 and an L-shaped ear 123 .

[0060] In this embodiment, the shape of the first slider 121 is consistent with the shape of the chute 1121. To enable the first slider 121 to fit into the chute 1121, the first slider 121 and the chute 1121 have the same structure, both in a cross shape, so that each first slider 121 can fit into each chute 1121 one-to-one and slide along the chute 1121.

[0061] Each first sliding block 121 is installed in parallel on one side of the second supporting plate 122 , and the L-shaped lifting ear 123 is installed on the other side of the second supporting plate 122 .

[0062] The installation method of the first sliding block 121 and the L-shaped lifting ear 123 and the second supporting plate 122 is not limited. For example, the installation method provided in this embodiment is welding.

[0063] After the first slider 121 and the L-shaped ear 123 are installed, a fixing screw hole 40 is drilled in the sliding ear assembly 12. The fixing screw hole 40 is hidden by the fixing bolt 30 in the figure. The fixing bolt 30 passes through the fixing screw hole 40 in the sliding ear assembly 12 and is fixed in the fixing screw hole 40 in the slide groove 1121.

[0064] Before the battery pack 20 is installed and secured, the installation position of the sliding ear assembly 12 can be adjusted according to actual conditions. When the battery pack 20 is installed and secured, the installation position of the sliding ear assembly 12 is determined, and the fixing bolt 30 passes through the fixing screw hole 40 in the sliding ear assembly 12 and is fixed in the fixing screw hole 40 of the slide groove 1121, thereby securing the sliding ear assembly 12 and preventing it from slipping during use.

[0065] In order to further improve the flexibility and versatility of the lifting lug device in practical applications and reduce the design complexity and time cost of the lifting lug device, please refer to Figure 6 This embodiment further provides another battery pack 20, which includes a battery pack body 60 and a lifting lug device 10. The lifting lug device 10 can be provided on any side of the battery pack body 60. Compared with the previous embodiment, this embodiment provides another lifting lug device.

[0066] Please refer to Figure 7 In this embodiment, the ear device 10 includes a base 11, a sliding guide rail assembly 13 and a sliding ear assembly 12.

[0067] The base 11 is mounted on the battery pack 20 , and the sliding ear assembly 12 is mounted on the base 11 via the sliding guide rail assembly 13 .

[0068] Before the battery pack 20 is installed, the installation position of the sliding ear assembly 12 can be adjusted. In one possible implementation, the sliding rail assembly 13 can slide along the base 11, and the sliding ear assembly 12 can slide along the sliding rail assembly 13, thereby achieving "double sliding" adjustment of the sliding ear assembly 12. Based on this structure, the actual installation position of the sliding ear assembly 12 can be adjusted by the sliding rail assembly 13 and the sliding ear assembly 12.

[0069] To further improve the flexibility of the lug device 10, please refer to Figure 8 A sliding slot 113 is opened in the base 11, and a plurality of fixing screw holes 40 are drilled in the sliding slot 113. The fixing screw holes 40 are linearly distributed in the sliding slot 113, and the base 11 is drilled with fixing screw holes 40.

[0070] Please refer to Figure 9 In this embodiment, the sliding guide rail assembly 13 includes a second slider 131 and a sliding rail 132.

[0071] The second slider 131 is slidably mounted on the sliding slot 113 . The second slider 131 can slide along the sliding slot 113 . The slide rail 132 is fixedly mounted on the second slider 131 .

[0072] Among them, before the battery pack 20 is installed and fixed, the installation position of the sliding guide rail assembly 13 can be adjusted by sliding the second slider 131. For example, in this embodiment, the sliding rail 132 and the second slider 131 are drilled with fixing screw holes 40 at corresponding positions. The mounting bolts 50 pass through the fixing screw holes 40 on the sliding rail 132 and are fixed in the fixing screw holes 40 on the second slider 131 to achieve fixed installation of the sliding rail 132. The second slider 131 provided in this embodiment is slidably installed on the sliding slot 113. The second slider 131 can not only adjust its own position by sliding, but also drive the sliding rail 132 to slide together. Based on this structure, the installation position of the sliding guide rail assembly 13 can be adjusted by the second slider 131. When the battery pack 20 is installed and fixed, the sliding guide rail assembly 13 can be fixed by bolts.

[0073] In one possible implementation, a fixing screw hole 40 is drilled in the second slider 131. The fixing bolt 30 can pass through the fixing screw hole 40 on the second slider 131 and be fixed in the fixing screw hole 40 in the sliding slot 113, thereby fixing the sliding rail assembly 13. Based on this structure, the sliding rail assembly 13 can be fixed by the fixing screw 30 during use to prevent accidental sliding.

[0074] In this embodiment, the shape of the slide rail 132 is not limited, as long as the sliding ear assembly 12 can be slidably mounted on the slide rail 132. For example, the shape of the slide rail 132 can be a ring, a rectangular parallelepiped, a curved surface, etc. When the battery pack 20 is a sphere, the slide rail 132 can be configured as a ring. When the surface of the battery pack 20 is a curved surface, the shape of the slide rail 132 can be specifically configured to suit the curved surface. For ease of demonstration, a rectangular parallelepiped-shaped slide rail 132 is selected in this embodiment.

[0075] In order to improve the flexibility of the ear device 10, this embodiment also provides a structure of a sliding ear assembly, please refer to Figure 10 The sliding ear assembly 12 includes a third sliding block 124 and an L-shaped ear 123 .

[0076] The third slider 124 is slidably mounted on the slide rail 132 , and the third slider 124 can slide along the slide rail 132 to change its position. The L-shaped lifting lug 123 is mounted on the third slider 124 .

[0077] The manner in which the L-shaped lifting ear 123 is mounted on the third sliding block 124 is not limited, as long as the stability of the L-shaped lifting ear can be ensured. For example, the mounting method provided in this embodiment is welding.

[0078] To further improve the stability of the sliding ear assembly 12 during use and ensure the stability and safety of the battery pack 20, the sliding ear assembly 12 must be able to be fixed on the slide rail 132 at the installation position. For example, the third slider 124 provided in this embodiment can slide along the slide rail 132 to change its own position. At the same time, a fixing screw hole 40 is drilled on the third slider 124. After the installation position of the sliding ear assembly 12 is determined, the fixing screw hole 40 is drilled at the corresponding position on the slide rail 132. The fixing bolt 30 passes through the fixing screw hole 40 on the third slider 124 and the slide rail 132 to be fixed in the external nut, thereby achieving the fixation of the sliding ear assembly 12. Based on this structure, the sliding ear assembly 12 can not only slide, but also be fixed when it slides to the installation position, preventing the battery pack 20 from accidentally shifting and sliding.

[0079] In summary, the lifting ear device provided in this embodiment is suitable for a battery pack. By installing the base on the battery pack and sliding the lifting ear assembly on the base, the sliding lifting ear assembly can change its position by sliding, thereby improving the flexibility of the lifting ear device to adapt to the installation requirements in different scenarios.
