Technical Field

[0001] The invention relates to the technical field of battery cores, and in particular to a supporting cup. Background Art

[0002] During the processing of battery cells, in order to facilitate the positioning and protection of the battery cells, it is generally necessary to set a support cup on the outside of the battery cell to carry the battery cell. The current support cup generally adopts an integral structural design, and the battery cell is installed into the battery cell by insertion. This design has obvious shortcomings in the process of installing the battery cell into the support cup: since the battery cell is bound to produce relative movement with the outer edge of the support cup when being installed, this inevitably leads to friction between the two, which can easily cause the electrode material on the surface of the battery cell to fall off, affecting the processing quality of the battery cell. Summary of the invention

[0008] In one embodiment, an anti-skid body is provided on the end of the support body facing the battery core, and the anti-skid body elastically abuts against the side of the battery core to limit the relative sliding of the battery core and the support body.

[0009] In one embodiment, the flexible structure further includes an elastic body, wherein the elastic body penetrates through the plurality of support bodies along the circumference of the battery core, and the elastic body drives the support bodies to closely abut against the sides of the battery core through elastic deformation.

[0011] In one embodiment, the support cup further includes a magnetic structure, and any two adjacent clamping members are magnetically connected via the magnetic structure.

[0012] In one embodiment, the magnetic attraction structure includes a magnet and a magnetic attraction member, and the magnet and the magnetic attraction member are respectively disposed on every two adjacent clamping members, and the magnet and the magnetic attraction member are positioned opposite to each other.

[0013] In one embodiment, the magnet is configured as an electromagnet; and / or the magnetic attraction structure further includes a pin and a pin hole, the pin and the pin hole are respectively arranged on every two adjacent clamping members, and the pin is plugged into the pin hole.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0022] In order to alleviate the situation where the battery cell 10 and the support cup 20 are prone to wear during the disassembly and assembly process, the present technical solution proposes a support cup 20 for fixing the battery cell 10. The support cup 20 includes a clamping member 100. The clamping member 100 is provided with at least two, and at least two clamping members 100 are detachably connected to clamp the side of the battery cell 10.

[0023] In the technical solution of the present invention, the support cup 20 adopts a split design. By setting at least two clamping members 100, when the battery cell 10 is installed, the at least two clamping members 100 are connected and clamp the side of the battery cell 10 to fix the battery cell 10. In addition, the clamping members 100 can be detachably connected. When the battery cell 10 needs to be removed, the battery cell 10 can be released by simply disconnecting the clamping members 100. In the above structure, there is no relative movement between the battery cell 10 and the support cup 20 during the disassembly and assembly process of the battery cell 10, so no friction is generated between the two, thereby eliminating the hidden danger of surface wear of the battery cell 10, which is beneficial to improving the processing quality of the battery cell 10 and ensuring the reliability of the final product.

[0024] like Figures 1 to 4 In one embodiment of the present invention, the support cup 20 is composed of two independent clamping members 100. The two clamping members 100 can be installed around the side of the battery cell 10. The clamping members 100 can be connected to each other by a detachable connection method such as snap connection. In order to prevent the battery cell 10 from being scratched, a flexible lining material can be configured in each clamping member 100 to ensure that it will not be damaged when in contact with the battery cell 10. During the installation of the battery cell 10, the battery cell 10 is first placed in a predetermined position, and then the clamping members 100 are arranged around the side of the battery cell 10 in turn, and then the clamping members 100 are connected together. The connected clamping members 100 cooperate with each other to clamp and fix the battery cell 10 together. Then the support cup 20 and the battery cell 10 can be placed on the production line for circulation. During the circulation process, the support cup 20 always protects the battery cell 10 to prevent damage to the battery cell 10. When the battery cell 10 needs to be taken out after the processing is completed, the battery cell 10 can be released by simply loosening the connecting device between the clamping members 100. Since there is no friction between the battery cell 10 and the clamping piece 100 during the entire disassembly and assembly process, the risk of surface wear of the battery cell 10 is reduced and the integrity of the battery cell 10 is protected; of course, the number of clamping pieces 100 may be more than two, and the number of clamping pieces 100 may be flexibly selected according to the size of the battery cell 10, etc.

[0025] like Figure 4In order to ensure the stability of the battery cell 10 after being clamped, in one embodiment of the present invention, a mounting groove 110 is provided on the side of each clamping member 100, and a plurality of mounting grooves 110 are surrounded to form a mounting space with one side open, and one end of the battery cell 10 is accommodated in the mounting space. Among them, the cross-sectional shape of the mounting groove 110 along the radial direction of the battery cell 10 can be semicircular and the size can be adapted to the outer diameter of the battery cell 10. The mounting grooves 110 of the two clamping members 100 can form a cylindrical mounting space with an open top after being assembled; one end of the battery cell 10 is accommodated in the mounting space. This structure ensures that the battery cell 10 can be firmly limited in the mounting space to avoid shaking, thereby ensuring the accuracy of subsequent processing. In addition, during assembly, the battery cell 10 can be pre-installed in a mounting groove 110, and then the other clamping member 100 can be installed, making the installation of the battery cell 10 more intuitive and convenient; in addition, it can be imagined that this design is not only suitable for standard cylindrical battery cells 10, but can also adapt to other types of battery cells 10 (such as square, flat, etc.) by adjusting the cross-sectional shape of the mounting groove 110.

[0026] In one embodiment of the present invention, a flexible structure is provided in the mounting groove 110, and the flexible structure elastically abuts against the side of the battery cell 10. The flexible structure may be an elastic structure provided in the mounting groove 110, for example, a silicone block, which may cover the inner wall of the mounting groove 110. When assembled with the battery cell 10, the flexible structure abuts against the side of the battery cell 10, and the flexible structure may be elastically deformed. After the assembly with the battery cell 10 is completed, the side of the battery cell 10 will be wrapped by the flexible structure, and the flexible structure is in an elastically deformed state at this time. The provision of this structure can reduce the risk of wear of the battery cell 10 when it is installed in the support cup 20. In addition, the flexible structure can also tightly clamp the battery cell 10 to ensure that the battery cell 10 is firmly clamped. In addition, due to the deformable characteristics of the flexible structure, the size of the installation space can be adjusted by the deformation of the flexible structure, so as to adapt to battery cells 10 of different sizes, thereby improving the versatility of the support cup 20.

[0027] Figure 4A structural form of a flexible structure is shown. In this scheme, the flexible structure includes a support body 200, which is protruding from the inner wall of the mounting groove 110. A plurality of support bodies 200 are provided, and the plurality of support bodies 200 are spaced around the battery cell 10 to elastically abut the side of the battery cell 10. Among them, the support body 200 is a protrusion of the inner wall of the installation groove 110 protruding toward one side of the battery cell 10, and the support body 200 extends to the two ends of the installation groove 110 along the axial direction of the battery cell 10. The support body 200 is made of an elastic material, such as silicone, rubber, PET or other similar elastic polymers. There are multiple support bodies 200, and the multiple support bodies 200 are arranged around the battery cell 10 in the installation groove 110 at intervals, thereby ensuring that all directions of the side of the battery cell 10 are uniformly supported and protected. In addition, the support body 200 can be bent. In this way, through the bending of the support body 200, the size of the installation space surrounded by the multiple support bodies 200 can be changed, thereby adapting to battery cells 10 of different sizes. In addition, since each support body 200 is independent of each other, it is easier to bend and deform, so the size of the installation space can be better adjusted and the force on the side of the battery cell 10 is reduced. In addition, in another embodiment of the present invention, an anti-skid body 300 is provided on the end of the support body 200 facing the battery cell 10. The anti-skid body 300 elastically abuts against the side of the battery cell 10 to limit the relative sliding of the battery cell 10 and the support body 200. The anti-skid body 300 can be made of a material with a large friction coefficient such as rubber or silicone. The setting of the anti-skid body 300 can further ensure the stability of the position of the battery cell 10.

[0028] In one embodiment of the present invention, the flexible structure further includes an elastic body 400, which penetrates through the plurality of support bodies 200 along the circumference of the battery core 10, and the elastic body 400 drives the support body 200 to closely contact the side of the battery core 10 through elastic deformation; in this solution, the elastic body 400 can be a strip structure with elasticity such as a coil spring or a rubber strip, and a connection hole is provided on each support body 200 of each clamping member 100, and the connection holes on each support body 200 are relatively located, and the elastic body 40 0 passes through the connection hole and the two ends of the elastic body 400 are fixed to the clamping member 100. In this way, when the battery cell 10 is loaded, the support body 200 is bent, and the elastic body 400 will be stretched and deformed along the radial direction of the battery cell 10. The elastic force generated by the stretching deformation of the elastic body 400 prompts the support body 200 to fit more closely with the side of the battery cell 10. When the two clamping members 100 are connected, the elastic bodies 400 of the two clamping members 100 are equivalent to being clamped on the side of the battery cell 10, so that the stability of the fixation of the battery cell 10 can be further ensured. In addition, in another embodiment of the present invention, at least two elastic bodies 400 are provided, and at least two elastic bodies 400 are arranged at intervals along the axial direction of the battery cell 10. In this way, the side of the battery cell 10 can be clamped and fixed at different positions in the axial direction, which is conducive to further improving the stability of the fixation.

[0029] In one embodiment of the present invention, the support cup 20 also includes a magnetic structure, and any two adjacent clamping members 100 are magnetically connected via the magnetic structure. The clamping members 100 are connected by magnetic attraction, which facilitates the disassembly and assembly of the clamping members 100 and is conducive to improving production efficiency. Figure 2 and Figure 3 A structural form of a magnetic attraction structure is provided. In this scheme, the magnetic attraction structure includes a magnet 500 and a magnetic attraction part 600. The magnet 500 and the magnetic attraction part 600 are respectively arranged on every two adjacent clamping parts 100, and the magnet 500 and the magnetic attraction part 600 are positioned opposite to each other. Among them, the magnet 500 can be made of permanent magnetic materials such as neodymium iron boron. The magnet 500 is embedded in the side wall of one clamping part 100. The magnetic part can be a structure such as an iron sheet that can be attracted by the magnet 500. The magnetic part is embedded in the side wall of another clamping part 100. During assembly, the magnet 500 can be attracted to the magnetic part. At this time, the side walls of the two clamping parts 100 are in contact with each other. In addition, the other side of the two clamping parts 100 can also be in contact with each other by using the magnet 500 and the magnetic attraction part 600. It will not be elaborated here.

[0030] In one embodiment of the present invention, the magnet 500 is configured as an electromagnet. In addition, a contact may be set at the bottom or side wall of the clamp 100, and the contact may be connected to the electromagnet through a wire. In addition, an electrode corresponding to the contact may be set on the production line. When the support cup is placed on the production line, the contact may dock with the electrode to realize the power supply of the electromagnet. With this arrangement, when the support cup is removed from the production line, the electromagnet is powered off and the battery cell can be taken out. When the support cup is placed on the production line, the electromagnet is powered on and the battery cell can be fixed by the support cup. In this way, the magnetic force is activated or shut down by controlling the on and off of electricity, thereby improving the flexibility of using the support cup. In addition, in order to ensure the docking accuracy between the clamping parts 100, the magnetic structure also includes a pin 700 and a pin hole 800. The pin 700 and the pin hole 800 are respectively arranged on every two adjacent clamping parts 100, and the pin 700 and the pin hole 800 are plugged into each other. The design of the pin 700 and the pin hole 800 ensures the precise alignment of the clamping parts 100 during connection, and the operator does not need to repeatedly align during docking, thereby improving the convenience of operation.
