Description

Technical Field

[0001] This utility model relates to the field of new energy battery technology, and more specifically, to a support component and a battery box assembly for a battery box. Background Technology

[0002] As energy storage cells evolve towards larger capacities, system integration is developing towards larger scales and higher energy densities. This places increasingly stringent requirements on the size and structure of energy storage packs (battery boxes). In practical applications, higher energy density is always better for battery boxes. In existing technologies, handles are typically installed on the battery box for ease of installation and removal. These handles, with their defined dimensions, occupy space. Furthermore, to facilitate handling, the handles are mounted on the front panel of the battery box, further limiting their space. Since no battery cells are located in this space, the overall energy storage capacity of the battery cells remains unchanged despite the increased overall size of the battery box, thus reducing the battery box's energy density.

[0026] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] It should be noted that, unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0029] To address the problem that the presence of handles in existing battery boxes affects their energy density, this invention provides a support component and a battery box assembly for battery boxes.

[0030] See Figures 1 to 3 The support assembly for the battery box includes a beam 1 and an operating part 2. The battery box 3 does not have a handle. The beam 1 has a support surface for fitting the battery box 3, which connects the support beam to the battery box 3. The operating part 2 is disposed on the beam 1 and embedded within the beam 1, either completely inside the beam 1 or partially protruding. Furthermore, the support surface of the beam 1 has a clearance area, which exposes one end of the operating part 2, so that it is concealed by the battery box when the support assembly is installed on the battery box.

[0031] In use, the battery box is installed on a battery rack in an energy container or other application scenario. When maintenance or replacement is required, the battery box needs to be removed from the battery rack. By placing the operating part 2 inside the beam 1, when the battery pack needs maintenance, the battery pack can be pulled out using the matching tool in conjunction with the operating part 2, replacing the handle on the traditional battery pack. This saves space occupied by the entire battery pack. By reducing the material of the handle, the cost of the entire battery pack is reduced, and the energy density of the battery pack is increased. In one embodiment, the operating part 2 is a bushing of the battery box 3, and the matching tool is a configuration tool hook.

[0032] In this utility model, in order to facilitate the removal of the battery box 3 during maintenance, the operating part 2 is set at the end of the beam 1. In this way, when removing the battery box 3, it is only necessary to slightly insert the matching tool to cooperate with the operating part 2, thereby facilitating the maintenance and removal of the battery box 3.

[0033] During the removal of the battery box 3, a matching tool needs to be inserted into the operating unit 2. The battery box 3 is removed by the cooperation of the matching tool and the operating unit 2. To facilitate the removal of the battery box 3 and to allow for the selection of a convenient matching tool, the operating unit 2 has a pickup channel 21. During the removal of the battery box 3, the matching tool is inserted into the pickup channel 21 to achieve cooperation between the tool and the operating unit 2, thereby removing the battery box 3. Preferably, the matching tool can be a hook-like device to cooperate with the pickup channel 21.

[0034] The length of the pickup channel 21 should be less than or equal to the thickness of the beam 1, preferably less than the thickness of the beam 1. When the length of the pickup channel 21 is equal to the thickness of the beam 1, the pickup channel 21 completely penetrates the beam 1. During the removal of the battery box 3, protruding foreign objects may get stuck in the pickup channel 21 on the support surface that contacts the lower surface of the beam 1, thus affecting the removal process of the battery box 3. Therefore, the depth of the pickup channel 21 is set to be less than the thickness of the beam 1, so that the pickup channel 21 will not penetrate the beam 1, the above situation will not occur, and the removal of the battery box 3 will be more convenient.

[0035] When selecting beam 1, a hollow beam is chosen to reduce the overall weight of the battery pack and save on material usage. In this case, the operating part 2 should include a sleeve, with its first end connected to the inner cavity of beam 1 and its second end extending to the support surface, so that the pickup channel 21 is located inside the sleeve. Hook-type devices are also selected as the matching tools to facilitate cooperation with the sleeve.

[0036] The second end of the sleeve extends to the support surface. At this point, the second end of the sleeve can protrude from the support surface or be flush with it. However, the optimal solution is for it to protrude from the support surface. During the handling of the battery box 3, bolts need to be screwed into the sleeve. During the bolt screwing process, since the second end of the sleeve protrudes from the support surface, the bolt head will not contact the support surface, thereby reducing damage to the support surface and protecting the support surface of the beam 1.

[0037] In this invention, the operating unit 2 also has a limiting structure, which is disposed within the pickup channel 21. During the removal of the battery box 3, the operating unit 2 is used in conjunction with an operating tool that is paired with it. To increase the stability of the cooperation between the operating unit 2 and the paired tool, a limiting structure is provided within the pickup channel 21. The use of the limiting structure in conjunction with the paired tool increases the stability of the paired tool within the pickup channel 21, thereby increasing the stability of the battery box 3 removal process.

[0038] When the accessory tool is a hook-like device, the limiting structure can be a limiting groove formed on the side wall of the pickup channel 21. By inserting the hook of the accessory tool into the limiting groove, the operation part 2 and the pickup tool can be engaged. In another embodiment, the limiting structure is made of magnetic material. Through magnetic force, it engages with the accessory tool of the sticker, increasing the stability of the engagement between the accessory tool and the pickup channel 21, thereby increasing the stability of the battery box 3 being picked up.

[0039] See Figure 2 The cross-section of beam 1 is trapezoidal, and the width of the supporting surface is greater than the width of the surface on the opposite side of beam 1. By adopting a trapezoidal structure, the amount of material used can be reduced, while the uneven deformation of beam 1 can be reduced, thereby increasing the stability and service life of beam 1.

[0040] The support assembly also includes connectors 22, and there are multiple connectors 22. The multiple connectors 22 are spaced apart along the length of the beam 1 and located on the side of the battery box 3.

[0041] The connecting assembly includes a first plate segment, a second plate segment, and a third plate segment connected sequentially. The first plate segment is located on the side wall of the battery box 3, and the length of the third plate segment is less than the length of the first plate segment. A connecting gap is formed between the first and third plate segments. In use, external parts enter from below the third plate segment and then are vertically offset so that the external parts are placed within the connecting gap, thereby connecting the battery box 3 to the external parts. The battery box 3 is connected to the external parts through the connector 22, increasing the stability of the battery box 3 during transportation.

[0042] See Figure 3 and Figure 4 The battery box assembly includes a battery box 3 and a support assembly. The support assembly is connected to the battery box 3, and the operating part 2 of the support assembly is offset from the battery box 3. Because the operating part 2 of the support assembly is offset from the battery box 3, the battery box 3 will not obstruct the operating part 2, thus ensuring that the removal of the battery box 3 is not affected.

[0043] There are at least two support components, wherein the two side support components are respectively located on a set of opposite sides of the battery box 3, and the operating parts 2 of different support components are all located on the same side of the battery box 3.

[0044] In one embodiment, there are two support components, located on opposite sides of the battery box 3, and symmetrically distributed with respect to the centerline of the battery box 3. This allows the two support components to distribute the weight of the battery box 3 evenly, preventing significant differences in the lifespan of the support components due to uneven stress, and also preventing deformation of one support component due to uneven stress, thus improving the lifespan of the support components. In this embodiment, the number of support components can also be any even number, all symmetrically distributed with respect to the centerline of the battery box 3.

[0045] In another embodiment, the number of support components is three or more, which is used when the weight of the battery box 3 is uneven. More support components are placed on the heavier side of the battery box 3 to distribute more pressure and make more efficient use of the support components.

[0046] In this invention, the battery box assembly also includes an auxiliary component 4, which protrudes from the battery box 3. The auxiliary component 4 can be a block structure, which facilitates the installation or assembly of the battery box 3, improving the installation efficiency of the battery box 3. In this embodiment, the auxiliary component 4 is located at the end of the battery box 3, and can cooperate with the operating part 2 during battery box 3 installation to facilitate the removal of the battery box 3.

[0047] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0048] 1. By setting the operating part 2 inside the beam 1, when the battery pack needs maintenance, the matching tools are used in conjunction with the operating part 2 to pull out the battery pack, replacing the handle on the traditional battery pack, thereby saving the space occupied by the entire battery pack. Due to the reduction of the handle material, the cost of the entire battery pack is reduced, and the energy density of the battery pack is increased.

[0049] 2. The operating part 2 is set at the end of the beam 1. When removing the battery box 3, the matching tool only needs to be slightly inserted to cooperate with the operating part 2, which facilitates the maintenance and removal of the battery box 3.

[0050] 3. During the process of removing the battery box 3, the operating tool that is matched with the operating unit 2 is used in conjunction with the operating unit 2. In order to increase the stability of the cooperation between the operating unit 2 and the matching tool, a limiting structure is set in the pickup channel 21. By using the limiting structure in conjunction with the matching tool, the stability of the matching tool in the pickup channel 21 is increased, thereby increasing the stability of the battery box 3 removal process.
