The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0021] In the description of this application, the terms "center", "longitudinal", "lateral", "length", "width", "height", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0022] Furthermore, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first and second features are in direct contact, or that they are in indirect contact through an intermediate medium.

[0023] In the description of this application, the terms "first," "second," etc., are used to distinguish different objects and should not be construed as indicating or implying a specific order or primary / secondary relationship, or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature.

[0024] In the description of this application, the term "multiple" means two or more, unless otherwise explicitly specified. The term "multiple A's correspond to multiple B's in a one-to-one manner" can be understood as: the number of A's and the number of B's ​​are the same, and there is a one-to-one mapping relationship, that is, each A corresponds to only one B, and each B corresponds to only one A.

[0025] In the description of this application, unless otherwise explicitly specified, the terms "installation," "connection," "attachment," etc., should be interpreted broadly.

[0028] Battery cells are a crucial component of battery packs. During the manufacturing process of individual battery cells, when each cell is individually transferred to a vacuum environment for electrolyte injection, this process must be carried out inside a vacuum glove box. During this handling, battery cells are prone to tipping over, posing a risk of short circuits caused by the positive and negative terminals of one cell coming into contact with adjacent cells.

[0029] like Figure 1 As shown, in order to solve the above-mentioned technical problems, the embodiments of this application provide an anti-tipping transfer fixture 100, which relates to the field of battery technology and is mainly used to reduce the risk of short circuit caused by the tilting of battery cells 200.

[0030] It should be noted that the battery cell 200 primarily relies on the movement of metal ions between the positive and negative electrode plates to function. The battery cell 200 can be rectangular, cylindrical, flat, or other shapes; classified by packaging method, it can be a prismatic battery, cylindrical battery, pouch battery, etc., without specific limitations here. Classified by the type of metal ions, it can be a lithium-ion battery, sodium-ion battery, etc.; classified by the physical state of the electrolyte, it can be a liquid battery, i.e., using a liquid electrolyte (i.e., electrolyte solution). Of course, the battery cell 200 can also be a solid-state battery, i.e., using a solid-state electrolyte; the type of battery cell 200 is not specifically limited here.

[0031] It should be noted that the battery cell 200 can be indirectly applied to electrical devices or energy storage devices in the form of a battery pack, or it can be directly applied to electrical devices or energy storage devices without the form of a battery pack.

[0032] For example, electrical devices can be vehicles, mobile phones, portable devices, laptops, ships, spacecraft, electric toys, and power tools. Vehicles can be gasoline-powered cars, natural gas-powered cars, new energy vehicles, etc., and new energy vehicles can be pure electric vehicles, hybrid electric vehicles, range-extended electric vehicles, etc.; spacecraft can be airplanes, rockets, space shuttles, drones, spacecraft, etc.; electric toys include stationary or mobile electric toys, such as game consoles, electric car toys, electric ship toys, and electric airplane toys; power tools can be metal cutting power tools, grinding power tools, assembly power tools, and railway power tools, such as electric drills, electric grinders, electric wrenches, electric screwdrivers, electric hammers, impact drills, concrete vibrators, and electric planers; energy storage devices include energy storage containers, energy storage cabinets, energy storage power stations, wind power generation devices, solar power generation devices, mobile power devices, temporary power supply devices, etc.; no specific limitations are made on the types of electrical devices and energy storage devices here.

[0033] like Figures 1 to 3 As shown, the anti-tipping transfer fixture 100 provided in this embodiment has a first direction X, a second direction Y and a third direction Z that are perpendicular to each other. The anti-tipping transfer fixture 100 includes an insulating shell 110 and an anti-tipping bracket 120.

[0034] The insulating housing 110 has a receiving cavity 111 and an opening 112 communicating with the receiving cavity 111. The insulating housing 110 also has two large surface sides 113 arranged opposite each other in the second direction Y. The receiving cavity 111 is used to receive a part of the battery cell 200. The opening 112 is located on one side of the insulating housing 110 in the third direction Z. Multiple anti-tipping brackets 120 are provided. The multiple anti-tipping brackets 120 are spaced apart in the first direction X. Each anti-tipping bracket 120 includes a first support part 121 and two second support parts 122. The first support part 121 is connected to the two second support parts 122 respectively. The first support part 121 abuts against the side of the insulating housing 110 away from the opening 112 in the third direction Z. The insulating housing 110 is located between the two second support parts 122 in the second direction Y. The two second support parts 122 abut against the two large surface sides 113 one by one.

[0035] For example, the materials of the insulating housing 110 and / or the anti-tipping bracket 120 can be selected from the following categories: 1. Synthetic organic insulating materials: plastics (e.g., polyethylene, polyvinyl chloride, polypropylene, polytetrafluoroethylene, epoxy resin, etc.), synthetic rubbers (e.g., silicone rubber, nitrile rubber, etc.), synthetic fibers (e.g., polyester fiber, nylon, etc.); 2. Natural organic insulating materials: wood, natural rubber, etc.; 3. Inorganic insulating materials: ceramics, glass, mica, quartz, asbestos, etc.; 4. Polymer insulating materials: polycarbonate, polyimide, etc., without specific limitations.

[0036] It is understood that this embodiment provides an anti-tipping transport fixture 100, which includes an insulating shell 110. The insulating shell 110 accommodates a portion of a battery cell 200 through a receiving cavity 111, providing insulation protection between adjacent battery cells 200. It also includes multiple anti-tipping supports 120. The first support portion 121 of each anti-tipping support 120 abuts against the side of the insulating shell 110 away from the opening 112, and the two second support portions 122 of each anti-tipping support 120 abut against the two large-surface sides 113 of the insulating shell 110, providing support for the insulating shell 110. This effectively reduces the risk of short circuits caused by the battery cell 200 tipping over, and improves the operational safety during the transport of the battery cell 200.

[0037] In addition, the insulating housing 110 accommodates a portion of the battery cell 200 through the receiving cavity 111, while the other portion of the battery cell 200 is exposed outside the insulating housing 110, which facilitates the placement and removal of the battery cell 200.

[0038] like Figure 3 and Figure 4 As shown, in some embodiments, the insulating housing 110 has a plurality of positioning grooves 114 on the side away from the opening 112 in the third direction Z, and the first support parts 121 of the plurality of anti-tipping brackets 120 are located in the plurality of positioning grooves 114 in a one-to-one correspondence.

[0039] It is understandable that by setting multiple positioning slots 114, multiple anti-tipping brackets 120 can be positioned and limited, which facilitates operation and allows the anti-tipping brackets 120 to better support the insulating shell 110.

[0040] like Figure 3 , Figure 5 and Figure 6 As shown, further, in the third direction Z, the side of the first support 121 away from the opening 112 and the side of the second support 122 away from the opening 112 are both flush with the side of the insulating housing 110 away from the opening 112. This makes the contact area between the anti-tipping transfer fixture 100 and the worktable surface larger, thereby having higher stability and helping to further reduce the risk of short circuit caused by the battery cell 200 tipping over.

[0041] like Figure 6 As shown, further, on the third direction Z, the size of the large surface side 113 is H1, and the size of the second support part 122 is H2, satisfying: 0.1≤H2 / H1≤0.3.

[0042] For example, H2 / H1 can be any value from 0.1, 0.12, 0.15, 0.2, 0.21, 0.22, 0.24, 0.25, 0.26, 0.29, 0.3 or any value from a range of any two of them, without any specific limitation here.

[0043] Understandably, if H2 / H1 is too large, the anti-tipping bracket 120 will occupy too much space, which is not conducive to the transfer of the battery cell 200. If H2 / H1 is too small, the anti-tipping bracket 120 will not provide sufficient support height for the insulating shell 110, which is not conducive to reducing the risk of the battery cell 200 tipping over. By controlling H2 / H1 within the range of 0.1 to 0.3, the anti-tipping bracket 120 achieves both a compact structure and good support effect.

[0044] like Figure 5 and Figure 6 As shown, in some embodiments, the orthographic projection of the second support portion 122 onto a plane perpendicular to the first direction X is a right triangle. The second support portion 122 has a straight side 1221 and an inclined side 1222. The straight side 1221 is in contact with the large surface side 113, and the inclined side 1222 is located on the side of the straight side 1221 away from the large surface side 113 in the second direction Y.

[0045] It is understandable that, since the second support part 122, which is a right-angled triangle, has high stability, it can better support the insulating shell 110 and provide a more reliable anti-tipping function by contacting the insulating shell 110 with its straight side 1221 and the large side 113 of the insulating shell 110 in a surface contact manner.

[0046] like Figure 1 and Figure 6 As shown, in some embodiments, in the first direction X, the size of the large surface side 113 is W1, the number of anti-tipping brackets 120 is N, and the size of the second support part 122 is W2, satisfying: 0.1≤N×W2 / W1≤0.3.

[0047] For example, the number N of the anti-tipping brackets 120 can be two, three, four, five, etc., and no specific limitation is made here.

[0048] It should be noted that N×W2 can be understood as the sum of the dimensions of the second support portion 122 of multiple anti-tipping brackets 120.

[0049] For example, N×W2 / W1 can be any value from 0.1, 0.12, 0.125, 0.16, 0.2, 0.21, 0.22, 0.23, 0.25, 0.27, 0.29, 0.3 or any value from a range of any two of them, without any specific limitation here.

[0050] Understandably, if N×W2 / W1 is too large, the anti-tipping bracket 120 will occupy too much space, which is not conducive to the transfer of the battery cell 200. If N×W2 / W1 is too small, the anti-tipping bracket 120 will not provide sufficient support width for the insulating shell 110, which is not conducive to reducing the risk of the battery cell 200 tipping over. By controlling N×W2 / W1 within the range of 0.1~0.3, the anti-tipping bracket 120 achieves both a compact structure and good support effect.

[0051] It should be noted that when both 0.1≤H2 / H1≤0.3 and 0.1≤N×W2 / W1≤0.3 are satisfied, the anti-tipping bracket 120 has a larger supporting area on the insulating shell 110, and has a better anti-tipping effect.

[0052] like Figure 7 As shown, in some embodiments, the first support portion 121 and the two second support portions 122 are integrally formed to constitute the anti-tipping bracket 120. It can be understood that the first support portion 121 and the two second support portions 122 constitute an integrally formed structure, which is convenient for manufacturing and has high structural stability, and helps to improve the support effect on the insulating shell 110.

[0053] For example, the one-piece molded structure can be formed by injection molding, 3D printing, wire cutting, stamping, etc., without any specific limitation.

[0054] like Figure 7 As shown, in some embodiments, the second support portion 122 is provided with a first rounded chamfer 1223 on the side of the third direction Z near the opening 112 (the structure of the first rounded chamfer 1223 is not shown in the figures); and / or, the second support portion 122 is provided with a second rounded chamfer 1224 on the side of the second direction Y away from the large surface side 113.

[0055] Understandably, by setting the first rounded chamfer 1223 and the second rounded chamfer 1224, the smoothness of the edge of the anti-tipping bracket 120 is increased, the risk of workers being scratched by the sharp edge of the anti-tipping bracket 120 is reduced, and the operational safety of the battery cell 200 during the transfer process is improved.

[0056] In some embodiments, the first support portion 121 has a first anti-slip layer on the side of the third-direction Z-axis away from the opening 112; and / or, the second support portion 122 has a second anti-slip layer on the side of the third-direction Z-axis away from the opening 112. This enables the anti-tipping bracket 120 to have an anti-slip function, thereby reducing the risk of the battery cell 200 slipping.

[0057] In some embodiments, the insulating housing 110 has a third anti-slip layer on the side of the third direction Z away from the opening 112. This enables the insulating housing 110 to also have an anti-slip function, thereby further reducing the risk of slippage of the battery cell 200.

[0058] For example, the first anti-slip layer / second anti-slip layer / third anti-slip layer can be selected from rubber layer, silicone layer, frosted layer formed by spraying, etc., and no specific limitation is made here.

In the description of this application, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. Furthermore, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this application.
