[0008] Therefore, the first aspect of the utility model provides a holding component.

[0009] In the technical scheme, a holding component applied to the energy storage device is provided.

[0010] Specifically, the energy storage device includes a battery box and an energy storage converter, the storage battery in the battery box can store a large amount of electric energy, and the battery box can supply power to the electric equipment after being connected with the electric equipment.

When it is necessary to carry the battery box through the holding component, the holding component can be installed on the first mounting position of the battery box through the first connecting portion, so that the user can lift and move the battery box through the holding component, and after the carrying work of the battery box is completed, the holding component can be detached from the first mounting position.

[0012] Correspondingly, the holding component can also be connected with the energy storage converter through the body, for example, a second mounting position is arranged on the energy storage converter, a second connecting portion is arranged on the holding component corresponding to the second mounting position, and the second connecting portion is matched with the second mounting position. When it is necessary to carry the energy storage converter through the holding component, the holding component can be installed on the second mounting position of the energy storage converter through the second connecting portion, so that the user can lift and move the energy storage converter through the holding component, and after the carrying work of the energy storage converter is completed, the holding component can be detached from the second mounting position.

[0013] In summary, the holding component proposed in the application can be selectively installed on the battery box or the energy storage converter according to actual needs, so that the same holding component can meet the carrying needs of the battery box and the carrying needs of the energy storage converter, respectively, compared with designing a grabbing structure on the battery box and the energy storage converter respectively, the structural complexity of the battery box and the energy storage converter is reduced, and the production cost of the two is reduced. When the battery box and the energy storage converter do not need to be carried, the holding component can be detached, so that the holding component does not occupy the external space of the battery box and the energy storage converter, and compared with the embedded hidden design, the detachable holding component also does not occupy the size of the shell.

[0017] In the technical scheme, the first opening is arranged on the body, and the shape of the first opening is matched with the clamping structure on the battery box, so that the first connecting part corresponding to the battery box is formed on the holding part. When the battery box needs to be carried, the holding part is clamped on the battery box through the first opening, and the battery box and the first opening are limited to each other, so that the user can lift and move the battery box through the holding part.

[0018] Correspondingly, the second opening is also arranged on the body, and the shape of the second opening is matched with the second bolt, so that the second connecting part corresponding to the second mounting position is formed on the holding part. When the energy storage converter needs to be carried, the holding part is clamped between the head of the second bolt and the energy storage converter through the second opening, and the second bolt and the second opening are limited to each other, so that the user can lift and move the energy storage converter through the holding part.

[0019] Therefore, by arranging the first opening on the body, the detachable connection requirement of the battery box and the holding part is met. Correspondingly, by arranging the second opening on the body, the detachable connection requirement of the energy storage converter and the holding part is met. Therefore, a single holding part can meet the carrying requirements of the battery box and the energy storage converter, thereby reducing the production cost of the energy storage device.

The width of the first strip-shaped hole is greater than the diameter of the rod part of the first bolt, and the width of the first strip-shaped hole is smaller than the maximum size of the head of the first bolt in the radial direction, so that the rod part of the first bolt can pass through the strip-shaped hole, but the head of the first bolt cannot pass through the strip-shaped hole.

[0023] In the assembling process, the head of the first bolt is first inserted through the first circular hole, and then the rod of the first bolt is pushed into the first strip-shaped hole to complete the installation.

The width of the second strip-shaped hole is greater than the diameter of the rod of the second bolt, and the width of the second strip-shaped hole is less than the maximum size of the head of the second bolt in the radial direction, so that the rod of the second bolt can pass through the strip-shaped hole, but the head of the second bolt cannot pass through the strip-shaped hole.

[0032] In the assembly process, the head of the second bolt is first passed through the second circular hole, and then the rod of the second bolt is pushed into the second strip-shaped hole to complete the installation. In this case, because the head of the second bolt cannot pass through the second strip-shaped hole below, the head of the second bolt can limit the holding part when the user carries the energy storage converter, thereby preventing the holding part and the energy storage converter from disassembling.

[0033] In the disassembly process, the rod of the second bolt is withdrawn from the second strip-shaped hole, and then the second bolt can be withdrawn from the second circular hole as a whole, so that the holding part is disassembled.

[0093] In this embodiment, the first opening 132 includes the first circular hole 1322 and the first strip-shaped hole 1324 in communication.

[0094] The diameter of the first circular hole 1322 is greater than the maximum dimension of the head of the first bolt 112 in the radial direction, so that the head of the first bolt 112 can pass through the first circular hole 1322, and the rod of the first bolt 112 can also pass through the first circular hole 1322. The width of the first strip-shaped hole 1324 is greater than the diameter of the rod of the first bolt 112, and the width of the first strip-shaped hole 1324 is less than the maximum dimension of the head of the first bolt 112 in the radial direction, so that the rod of the first bolt 112 can pass through the strip-shaped hole, but the head of the first bolt 112 cannot pass through the strip-shaped hole.

[0095] During assembly, the head of the first bolt 112 is first passed through the first circular hole 1322, and then the rod of the first bolt 112 is pushed into the first strip-shaped hole 1324 to complete the installation. In this case, because the head of the first bolt 112 cannot pass through the lower first strip-shaped hole 1324, the holding component 130 can pull the head of the first bolt 112 through the first strip-shaped hole 1324 to pull the battery box 110.

[0098] As shown in Figure 2 , Figure 3 and Figure 5 , in some embodiments of the utility model, optionally, the extension direction of the first strip-shaped hole 1324 is parallel to the axial direction of the first circular hole 1322.

[0100] In this embodiment, the extension direction of the first strip-shaped hole 1324 is parallel to the axial direction of the first circular hole 1322.

[0101] By setting the first strip-shaped hole 1324 parallel to the axial direction of the first circular hole 1322, on the one hand, the first bolt 112 installed longitudinally on the top of the battery box 110 can be matched, so that the holding part 130 can stand above the battery box 110 after installation is completed, facilitating the user to lift the battery box 110. On the other hand, the holding part 130 needs to be first turned over by 90° and then drawn into the first circular hole 1322 during disassembly, otherwise the head of the first bolt 112 and the first strip-shaped hole 1324 will interfere, so as to realize the locking of the holding part 130 on the battery box 110, reduce the probability of the holding part 130 falling off during the process of carrying the battery box 110, and then realize the technical effects of improving the practicability and reliability of the holding part 130 and improving the carrying safety of the battery box 110.

[0102] In some embodiments of the utility model, optionally, the energy storage converter 120 is provided with a second bolt 122; the second hole 134 includes a second circular hole 1342 and a second strip-shaped hole 1344, the second circular hole 1322 and the second strip-shaped hole 1344 are communicated, and the rod part of the second bolt 122 can be clamped into the second strip-shaped hole 1344 through the second circular hole 1342; the diameter of the second circular hole 1342 is greater than the maximum size of the head of the second bolt 122 in the radial direction, and the width of the second strip-shaped hole 1344 is less than the maximum size of the head of the second bolt 122 in the radial direction.

The width of the second strip-shaped hole 1344 is greater than the diameter of the rod part of the second bolt 122, and the width of the second strip-shaped hole 1344 is less than the maximum size of the head of the second bolt 122 in the radial direction, so that the rod part of the second bolt 122 can pass through the strip-shaped hole, but the head of the second bolt 122 cannot pass through the strip-shaped hole.

[0105] During assembly, the head of the second bolt 122 is first passed through the second circular hole 1342, and then the rod part of the second bolt 122 is pushed into the second strip-shaped hole 1344 to complete the installation. In this case, because the head of the second bolt 122 cannot pass through the second strip-shaped hole 1344 below, the head of the second bolt 122 can limit the holding part 130 when the user carries the energy storage converter 120, thereby preventing the holding part 130 and the energy storage converter 120 from disassembling.
