[0002] Lithium-ion batteries are rechargeable batteries that store and release electrical energy by moving lithium ions between positive and negative electrodes. They have advantages such as high energy density, high operating voltage, long cycle life, low self-discharge rate, and no memory effect, and are widely used in mobile phones, laptops, electric vehicles, energy storage systems, and other fields. Lithium-ion batteries often use frames to facilitate the installation of battery cells. Multiple battery cells are stacked together in a certain structure and order using a frame to form a complete battery pack. The design and construction of this frame have a significant impact on the battery's performance, safety, and lifespan. The battery frame design needs to consider the arrangement, fixing, and thermal management of the batteries within the frame. Cylindrical batteries are often arranged vertically along their height. Cylindrical batteries need to be additionally fixed to the lower frame using brackets (usually plastic brackets) or glue.

[0003] Regarding the aforementioned technologies, the inventors believe that conventional lithium battery frames often adopt an integrated installation method, which can easily lead to the problem of several cells being piled up together during cell installation, causing inconvenience in cell management and making installation time-consuming and labor-intensive.

Detailed Implementation

[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 lithium battery frame structure that facilitates cell stacking and fixing, referring to... Figure 1 - Figure 2 The system includes a first base frame 1, a first rotating frame 5 mounted at the bottom of the first base frame 1, a second rotating frame 6 rotatably connected to one end of the first rotating frame 5, and a second base frame 2 rotatably mounted on the top of the second rotating frame 6. Both the first base frame 1 and the second base frame 2 have mounting grooves 3 on their inner walls. The lithium battery body 4 is installed in the mounting grooves 3. The first rotating frame 5 and the second rotating frame 6 facilitate the connection between the first base frame 1 and the second base frame 2. The rotation of the first rotating frame 5 and the second rotating frame 6 allows for easy adjustment of the distance between the first base frame 1 and the second base frame 2, effectively improving the convenience of placing the battery cells in the lithium battery frame and facilitating the organization of the battery cells.

[0024] Reference Figure 2A limiting frame 7 is rotatably connected to the surface of the first base frame 1. One end of the limiting frame 7 is engaged with a locking block 8, and one end of the locking block 8 is connected to the surface of the second base frame 2. The first base frame 1 and the second base frame 2 are connected by the limiting frame 7 and the locking block 8, which facilitates the fixation of the first base frame 1 and the second base frame 2 to ensure the overall stability of the frame. A heat sink 9 is installed between the first base frame 1 and the second base frame 2. The heat sink 9 dissipates the heat generated by the lithium battery body 4 during use, avoiding heat accumulation that may affect the use of the lithium battery body 4.

[0025] Reference Figure 3 - Figure 4 A sliding rod 10 is installed on the inner wall of the first base frame 1 and the second base frame 2. A shielding frame 12 is installed on the top of the sliding rod 10, and a handle 11 is installed on the top of the shielding frame 12. The shielding frame 12 shields the top of the lithium battery body 4, and the handle 11 controls the movement of the shielding frame 12, facilitating the installation and removal of the lithium battery body 4. A limiting block 14 is installed at the bottom of the sliding rod 10. The surface of the limiting block 14 is slidably connected to the surfaces of the first base frame 1 and the second base frame 2. The sliding rod 10 facilitates the up and down movement of the shielding frame 12, and the limiting block works in conjunction with the sliding rod 10. 14. To prevent the sliding rod 10 from detaching from the first base frame 1 and the second base frame 2, push springs 13 are installed on the inner walls of the first base frame 1 and the second base frame 2. The bottom end of the push spring 13 is connected to the top of the limiting block 14. The limiting block 14 is pushed by the push spring 13, thereby keeping the shielding frame 12 at the top of the sliding rod 10 connected to the top of the lithium battery body 4, effectively improving the shielding effect of the shielding frame 12. A shielding net 15 is installed on the inner wall of the shielding frame 12. The shielding net 15 facilitates the dissipation of heat in the heat sink 9 to ensure the heat dissipation effect of the frame.

[0026] The implementation principle of a lithium battery frame structure for easy cell stacking and fixing in this application embodiment is as follows: The lithium battery body 4 is installed in the mounting groove 3 within the first base frame 1 and the second base frame 2. The bottom ends of the first base frame 1 and the second base frame 2 are respectively rotatably connected to a first rotating frame 5 and a second rotating frame 6. One end of the first rotating frame 5 and one end of the second rotating frame 6 are rotatably mounted, facilitating the connection between the first base frame 1 and the second base frame 2 using the first rotating frame 5 and the second rotating frame 6. Furthermore, the rotation of the first rotating frame 5 and the second rotating frame 6 facilitates the connection between the first base frame 1 and the second base frame 2. The distance between them is adjusted. The surface of the first base frame 1 is rotatably connected to the limit frame 7. One end of the limit frame 7 is engaged with the locking block 8. One end of the locking block 8 is connected to the surface of the second base frame 2, so that the first base frame 1 and the second base frame 2 can be connected by the limit frame 7 and the locking block 8, thereby facilitating the fixation of the first base frame 1 and the second base frame 2 to ensure the overall stability of the frame. A heat sink 9 is installed between the first base frame 1 and the second base frame 2 to dissipate the heat generated by the lithium battery body 4 during use, so as to avoid heat accumulation affecting the use of the lithium battery body 4.

[0027] A sliding rod 10 can also be installed on the inner wall of the first base frame 1 and the second base frame 2. A shielding frame 12 is installed on the top of the sliding rod 10, and a handle 11 is installed on the top of the shielding frame 12. The shielding frame 12 can be used to shield the top of the lithium battery body 4, and the handle 11 can be used to control the movement of the shielding frame 12, which facilitates the installation and removal of the lithium battery body 4. A limit block 14 is installed at the bottom of the sliding rod 10. The surface of the limit block 14 is slidably connected to the surface of the first base frame 1 and the second base frame 2, so that the shielding frame 12 can be moved up and down with the help of the sliding rod 10, and the limit block 14 can be used to assist the limit block 14 in moving up and down. Block 14 prevents the sliding rod 10 from detaching from the first base frame 1 and the second base frame 2. Push springs 13 are installed on the inner walls of the first base frame 1 and the second base frame 2. The bottom end of the push spring 13 is connected to the top of the limiting block 14 so that the limiting block 14 can be pushed by the push spring 13, thereby keeping the shielding frame 12 at the top of the sliding rod 10 connected to the top of the lithium battery body 4, effectively improving the shielding effect of the shielding frame 12. A shielding net 15 is installed on the inner wall of the shielding frame 12 so that the heat in the heat sink 9 can be dissipated by the shielding net 15 to ensure the heat dissipation effect of the frame.

[0028] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
