Description

Technical Field

[0001] The present application relates to the technical field of battery packs, and particularly to a handling structure for a battery pack. Background Art

[0002] Currently, in existing energy storage systems, there are generally multiple battery packs stacked one above the other. For the convenience of stacking, these battery packs are generally designed in a cuboid shape. To facilitate the handling of the battery packs, the prior art usually designs handle structures on both sides of the battery pack respectively. Designing handles on both sides of each battery not only occupies too much space but also increases costs.

[0003] To reduce costs and space occupancy, some solutions have also been proposed in the prior art. For example, the utility model with the publication number CN220984714U provides a battery pack and a battery pack assembly, which adopts a threaded connection method to achieve a detachable connection between the handle and the battery pack, and no longer installs handles on the sides of each battery pack respectively. However, in this patent, when each handle is connected to the battery pack, the handle needs to be rotated to achieve threaded connection, resulting in a long connection process between the handle and the battery pack, affecting the handling efficiency; and repeatedly screwing the handle and the battery pack threadedly also easily causes wear of the thread teeth, making the thread teeth unable to engage and resulting in a slipping thread phenomenon. Therefore, the service life of the handle will also be limited. Summary of the Utility Model

[0004] Based on this, it is necessary to provide a handling structure for a battery pack, and its specific technical solution is as follows.

[0005] A handling structure for a battery pack includes:

[0006] A handle, including a handle body and a connecting column; a gripping portion is provided on the handle body; the connecting column is connected to the side surface of the handle body;

[0007] A limiting member, connected to the first surface of the battery pack and extending in a direction away from the first surface; a plugging hole for receiving the connecting column to insert is provided on the limiting member.

[0008] Further, the connecting column includes a column body and a limiting head; one end of the column body is connected to the handle body, and the other end is connected to the limiting head; the diameter of the limiting head is greater than the diameter of the column body, so that an annular gap is formed between the limiting head and the handle body.

[0009] Further, the plugging hole includes a first hole and a second hole that communicate with each other; the distance between the first hole and the first surface of the battery pack is greater than the distance between the second hole and the first surface of the battery pack; the diameter of the first hole is greater than or equal to the diameter of the column body and less than the diameter of the limiting head; the diameter of the second hole is greater than the diameter of the limiting head.

[0010] Further, the holding portion includes a through groove penetrating the handle body, and a continuous wavy groove is provided at one edge of the through groove away from the connecting column.

[0011] Further, an internal hexagonal hole is provided on the handle body.

[0012] Further, a plurality of internal hexagonal holes with different specifications are provided on the handle body.

[0013] Further, the limiting member includes a main board, a bottom board and a reinforcing board; the main board is connected to one side of the bottom board, the reinforcing board is connected between the main board and the bottom board, and two reinforcing boards are respectively located at both ends of the bottom board; the insertion hole is provided on the main board.

[0014] Further, the limiting member is in a trapezoidal shape with a smaller upper part and a larger lower part, so that the reinforcing board is arranged obliquely.

[0015] Further, it includes two oppositely arranged limiting members.

[0016] Beneficial effects: For a battery pack handling structure provided by the present utility model, by arranging a connecting column on the handle and a limiting member with an insertion hole on the battery pack, when handling the battery pack, the handler can hold the handle and insert the connecting column into the insertion hole to realize the cooperation between the handle and the limiting member. After the handling is completed, the connecting column can be withdrawn to realize the separation between the handle and the limiting member. The connection and separation processes between the handle and the limiting member are simple and fast, and can realize the rapid handling of the battery pack. Description of the Drawings

[0032] Embodiment

[0033] Refer to Figure 1 and Figure 2 As shown, this embodiment provides a handling structure for a battery pack 3, including a handle 1 and a limiting member 2. The handle 1 includes a handle body 11 and a connecting column 12. A holding portion 13 is provided on the handle body 11, enabling a handling person to hold the handle 1 through the holding portion 13. The connecting column 12 is connected to the side surface of the handle body 11 and extends along a direction perpendicular to the side surface of the handle body 11.

[0034] The limiting member 2 is connected to the first surface 31 of the battery pack 3, where the first surface 31 refers to the top surface of the battery pack 3 in the stacked state, and the limiting member 2 extends along a direction away from the first surface 31. A plug hole 21 for receiving the insertion of the connecting column 12 is provided on the limiting member 2.

[0035] When it is necessary to handle the battery pack 3, the handling person holds the handle 1 and inserts the connecting column 12 into the plug hole 21 to complete the assembly of the handle 1 and the battery pack 3. When the handling is completed, the handling person holds the handle 1 and separates the connecting column 12 from the plug hole 21 to complete the separation of the handle 1 and the battery pack 3. To ensure the stability during the handling process, two relatively arranged limiting members 2 are provided on the first surface 31 of the battery pack 3, and the handling person holds one handle 1 in each hand for handling.

[0036] A handling structure for a battery pack 3 provided in this embodiment enables the cooperation between the handle 1 and the limiting member 2 by setting a connecting column 12 on the handle 1 and a limiting member 2 with a plugging hole 21 on the battery pack 3. When handling the battery pack 3, the handler holds the handle 1 and inserts the connecting column 12 into the plugging hole 21 to complete the cooperation. After handling, the connecting column 12 is pulled out to separate the handle 1 from the limiting member 2. The connection and separation processes between the handle 1 and the limiting member 2 are simple and fast, enabling the quick handling of the battery pack 3.

[0037] Specifically, referring to Figure 4 As shown, the connecting column 12 includes a column body 14 and a limiting head 15. One end of the column body 14 is connected to the handle body 11, and the other end is connected to the limiting head 15. The diameter of the limiting head 15 is larger than that of the column body 14, forming an annular gap 16 between the limiting head 15 and the handle body 11. After the connecting column 12 is inserted into the plugging hole 21, the limiting member 2 is engaged with the annular gap 16, ensuring the stability of the cooperation between the connecting column 12 and the limiting member 2 and preventing the battery pack 3 from separating from the handle 1 during handling, thus avoiding losses.

[0038] Specifically, referring to Figure 3 As shown, the plugging hole 21 includes a first hole 22 and a second hole 23 that communicate with each other; the distance between the first hole 22 and the first surface 31 of the battery pack 3 is greater than the distance between the second hole 23 and the first surface 31 of the battery pack 3; the plugging hole 21 includes a first hole 22 and a second hole 23 that communicate with each other, that is, in the stacked state of the battery pack 3, the first hole 22 is located above the second hole 23. The diameter of the first hole 22 is greater than or equal to the diameter of the column body 14 and less than the diameter of the limiting head 15; the diameter of the second hole 23 is greater than the diameter of the limiting head 15. During handling, the handler holds the handle 1 to lift the battery pack 3, enabling the column body 14 to enter the first hole 22. Since the diameter of the first hole 22 is smaller than the diameter of the limiting head 15, it can better restrict the connecting column 12 from disengaging from the plugging hole 21, further ensuring the stability during handling. When handling is completed, only by moving the handle 1 downward can the connecting column 12 be pulled out to separate the handle 1 from the battery pack 3.

[0039] Specifically, to further ensure the stability after the connection between the handle 1 and the limiting member 2, two plugging holes 21 are provided on the limiting member 2, and two connecting columns 12 are provided at corresponding positions on the handle 1.

[0040] Specifically, the holding part 13 includes a through groove penetrating the handle body 11, and a continuous wavy groove 17 is provided on one edge of the through groove away from the connecting column 12. This continuous wavy groove 17 is used to accommodate fingers, making the handling more ergonomic and greatly reducing the burden on the palm during actual installation.

[0041] Specifically, a plurality of hexagon socket holes 18 are provided on the handle body 11, which can be used as a wrench for the handle 1 during the installation process of the battery pack 3, making the function of the handle 1 more diverse and reducing the number of tools required during the installation and handling of the battery pack 3. Specifically, four hexagon socket holes 18 are respectively provided at the four corners of the handle body 11, and the specifications of the respective hexagon socket holes 18 are different, specifically M4, M5, M6, and M8.

[0042] Specifically, referring to Figure 2 As shown, the limiting member 2 includes a main board 24, a bottom board 25, and two reinforcing plates 26. The main board 24 is connected to one side of the bottom board 25, and the reinforcing plates 26 are connected between the main board 24 and the bottom board 25, and the two reinforcing plates 26 are respectively located at both ends of the bottom board 25; the insertion hole 21 is provided on the main board 24. A connection groove corresponding to the position of the limiting member 2 is provided on the second surface 32 of the battery pack 3, and the connection groove is used to accommodate the insertion of the limiting member 2; the second surface 32 is opposite to the first surface 31. During the stacking process of the battery packs 3, the cooperation of the limiting member 2 and the connection groove can realize the stacking positioning of the battery packs 3. In order to facilitate the rapid positioning of the batteries during the stacking process, the limiting member 2 is in a trapezoidal shape with a smaller upper part and a larger lower part, so that the reinforcing plates 26 are arranged obliquely. Using the obliquely arranged reinforcing plates 26 for guiding and positioning can further accelerate the handling and stacking speed of the battery packs 3. Moreover, terminals 33 for power taking are respectively provided on the first surface 31 and the second surface 32 of the battery pack 3. Through the cooperation and positioning of the limiting member 2 and the connection groove, it is possible to prevent the terminals 33 from shifting during the docking process of the battery packs 3 and protect the terminals 33.

[0043] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, 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, it should be considered as within the scope described in this specification.

[0044] The above-described embodiments merely represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
