Technical Field

[0001] This application relates to the field of lithium battery electrode connectors, and more particularly to a foldable lithium battery electrode connector structure. Background Technology

[0002] Lithium-ion batteries are a type of battery that uses lithium metal or lithium alloy as the positive / negative electrode material and a non-aqueous electrolyte solution. Foldable lithium-ion batteries are a type of battery manufactured using special materials and technologies, which can achieve bending, folding, and other deformations while maintaining high performance. The core of this type of battery lies in the design of its internal structure and the selection of materials, which enable it to adapt to various deformations without sacrificing performance. The electrodes of lithium-ion batteries are often connected by connecting pieces. Lithium-ion battery connecting pieces are conductive components used to connect the various components inside the lithium-ion battery cell. They are usually made of conductive materials such as copper or aluminum. Their main function is to connect the positive and negative electrode plates, separators, and other components inside the battery to ensure that the current can flow smoothly, thereby completing the charging and discharging process of the battery.

[0003] Regarding the aforementioned technologies, the inventors believe that conventional connecting pieces, when installed, are often used to connect multiple battery packs. This can lead to difficulties for workers in repairing individual batteries when a problem occurs due to the obstruction caused by the connecting piece, resulting in inconvenience during use.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

The slider has a "T" shaped cross-section, and the size of the slider surface is adapted to the size of the inner wall of the connecting groove. One end of the slider is fixedly connected to the top of the rotating plate.

[0010] Preferably, a limiting block is fixedly installed at one end of the slider, one end of the limiting block is movably connected to one end of the control frame, and the size of the limiting block surface is larger than the size of the inner wall of the connecting groove.

[0022] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0023] This application discloses a foldable lithium battery electrode connection sheet structure, referring to... Figure 1 - Figure 2 The device includes a connecting frame 1, which is connected to the surface of the battery. A rotating plate 2 is installed on the inner wall of the connecting frame 1. A control frame 4 is installed on the top of the rotating plate 2, and a limit plate 5 is movably connected to the bottom of the rotating plate 2. The surface of the limit plate 5 is connected to the surface of the connecting frame 1. The limit plate 5 restricts the rotation angle of the rotating plate 2. The rotation of the rotating plate 2 facilitates the inspection of the battery position, avoiding the problem that the connecting piece will obstruct the inspection of the battery when a single battery is damaged. The inner wall of the rotating plate 2 is provided with a mounting hole 3, which facilitates the connection of the rotating plate 2 to the surface of the battery.

[0024] Reference Figure 2Two limiting brackets 6 are installed on the surface of the control frame 4. The surface of the limiting bracket 6 engages with the limiting slot 7 inside the connecting frame 1. The rotating plate 2 is fixed inside the connecting frame 1 by means of the limiting bracket 6 and the limiting slot 7. The rotating plate 2 can be opened by separating the limiting bracket 6 and the limiting slot 7. A connecting groove 9 is opened on the inner wall of the control frame 4. A slider 8 is slidably installed on the inner wall of the connecting groove 9. The bottom end of the slider 8 is connected to the top of the rotating plate 2. The slider 8 and the connecting groove 9 restrict the movement position of the control frame 4, effectively improving the stability of the movement of the control frame 4. A limiting block 10 is installed on one end of the slider 8. One end of the limiting block 10 is movably connected to one end of the control frame 4. The limiting block 10 restricts the movement range of the control frame 4, preventing the control frame 4 from detaching from the surface of the slider 8.

[0025] Reference Figure 2 - Figure 4 A push spring 11 is installed inside the slider 8. One end of the push spring 11 is fixedly connected to one end of the control frame 4. The push spring 11 pushes the control frame 4 to keep the limit frame 6 engaged with the limit slot 7, thereby improving the fixing effect of the rotating plate 2. A fixing bolt 12 is installed on the surface of the connecting frame 1. A connecting ring 13 is threadedly connected to the surface of the fixing bolt 12. One end of the connecting ring 13 is engaged with the rotating plate 2. The rotating plate 2 is installed in the connecting frame 1 by means of the fixing bolt 12 and the connecting ring 13. Separating the connecting ring 13 from the fixing bolt 12 facilitates the disassembly of the rotating plate 2. An auxiliary ring 14 made of rubber is installed on the surface of the fixing bolt 12. One end of the auxiliary ring 14 is movably connected to the surface of the connecting pipe. The auxiliary ring 14 improves the fixing effect of the connecting ring 13 and the fixing bolt 12, avoiding the problem of the connecting ring 13 loosening and falling off.

[0026] The implementation principle of the foldable lithium battery electrode connecting piece structure in this application embodiment is as follows: A rotating plate 2 is installed on the inner wall of a connecting frame 1. A control frame 4 is installed on the top of the rotating plate 2, and a limiting plate 5 is movably connected to the bottom end of the rotating plate 2. The surface of the limiting plate 5 is connected to the surface of the connecting frame 1, and the limiting plate 5 restricts the rotation angle of the rotating plate 2. This facilitates the inspection of the battery position by rotating the plate 2, avoiding the problem of the connecting piece obstructing the inspection of a single damaged battery. Two limiting frames 6 are installed on the surface of the control frame 4, and the surface of the limiting frame 6 engages with the limiting slot 7 inside the connecting frame 1, facilitating the use of the limiting frame 6 to limit the position of the battery. The slot 7 holds the rotating plate 2 fixed within the connecting frame 1, and the rotating plate 2 can be opened by separating the limiting frame 6 from the limiting slot 7. The inner wall of the control frame 4 is provided with a connecting groove 9, and a slider 8 is slidably installed on the inner wall of the connecting groove 9. The bottom end of the slider 8 is connected to the top of the rotating plate 2, so as to limit the movement position of the control frame 4 by means of the slider 8 and the connecting groove 9, effectively improving the stability of the movement of the control frame 4. A limiting block 10 is installed on one end of the slider 8, and one end of the limiting block 10 is movably connected to one end of the control frame 4, so as to limit the movement range of the control frame 4 by means of the limiting block 10, avoiding the problem of the control frame 4 detaching from the surface of the slider 8.

[0027] A push spring 11 can also be installed inside the slider 8. One end of the push spring 11 is fixedly connected to one end of the control frame 4, so that the control frame 4 can be pushed by the push spring 11 to keep the limit frame 6 locked with the limit slot 7, thereby improving the fixing effect of the rotating plate 2. A fixing bolt 12 is installed on the surface of the connecting frame 1. A connecting ring 13 is threadedly connected to the surface of the fixing bolt 12. One end of the connecting ring 13 is locked with the rotating plate 2, so that the rotating plate 2 can be installed in the connecting frame 1 by means of the fixing bolt 12 and the connecting ring 13. Separating the connecting ring 13 from the fixing bolt 12 makes it easy to disassemble the rotating plate 2. An auxiliary ring 14 made of rubber is installed on the surface of the fixing bolt 12. One end of the auxiliary ring 14 is movably connected to the surface of the connecting pipe, so that the fixing effect of the connecting ring 13 and the fixing bolt 12 can be improved by means of the auxiliary ring 14, avoiding the problem of the connecting ring 13 loosening and falling off.
