[0001] The utility model relates to the field of lithium batteries, in particular to a new type of lithium battery. Background Art

[0002] Lithium batteries are a type of battery that uses lithium metal or lithium alloy as positive / negative electrode materials and a non-aqueous electrolyte solution. Due to the extremely active chemical properties of lithium metal, the processing, storage, and use of lithium metal have very high environmental requirements. With the development of science and technology, lithium batteries have become mainstream.

[0003] According to a Chinese patent with publication number CN217740603U, a new type of lithium battery is disclosed. The utility model has a reasonable design structure. Through the clamping connection between the plug plate and the protective cover plate, the stable installation of the protective cover plate and the protective shell can be achieved, and the lithium battery body can be stably placed inside the protective shell to provide protection for it.

[0004] In response to the above-mentioned disclosed patent content, a cover plate is provided to seal the top of the shell. However, after the cover plate and the shell are closed, a small gap may still exist between the cover plate and the shell, resulting in poor sealing performance between the shell and the cover plate. As a result, external water vapor may enter the shell through the gap, which may easily cause the lithium battery to become damp and damaged over a long period of time, thereby reducing the protection effect on the lithium battery. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide a new type of lithium battery to solve the technical problem of poor sealing performance between the cover plate and the shell.

[0011] By adopting the above technical solution, when the movable seat moves, it will drive the card plate to move, and when the card plate is inserted into the card slot, it will limit and fix the cover plate.

[0012] Furthermore, a movable groove is provided on one side of the movable seat, a plurality of movable blocks are arranged inside the movable groove, and one side of the movable block is connected to the threaded sleeve.

[0013] By adopting the above technical solution, the threaded sleeve can drive the movable block to slide in the movable groove when it rotates, and the threaded sleeve can drive the movable seat to move at the same time.

[0014] Furthermore, the movable groove is annular, and the movable block is slidably connected to the movable groove.

[0018] Furthermore, the bottom of the pressure ring contacts the top of the movable ring, and the diameter of the pressure ring is the same as the diameter of the gasket ring.

[0019] By adopting the above technical solution, when the pressure ring moves downward, it will squeeze the compression airbag ring, so that the compression airbag ring is compressed, and the air inside it will enter the air guide tube.

[0020] Furthermore, the slot is in a ring shape, the inner wall and the outer wall of the insert ring are both in contact with the sealing airbag ring, and one side of the slider is connected to the movable ring.

[0021] By adopting the above technical solution, the insert ring can be inserted into the slot, and the sealing performance between the cover plate and the shell can be improved after the insert ring and the sealing airbag ring are fitted together.

[0022] In summary, the utility model mainly has the following beneficial effects:

[0023] The utility model is provided with a sealing component. When the cover plate is installed on the shell, the insert ring at the bottom of the cover plate will be inserted into the slot, and the pressure ring will squeeze the compression airbag ring. As the cover plate moves downward, the compression airbag ring is compressed by force, and the air inside it enters the air guide tube. The air then flows into the two sealing airbag rings through the air guide tubes, respectively, so that the sealing airbag rings expand and fit the inner wall and outer wall of the sealing airbag ring with the insert ring, thereby improving the sealing between the shell and the cover plate, preventing water vapor or dust from entering the shell through the gap between the cover plate and the shell, and further improving the moisture-proof and dust-proof effect of the shell. At the same time, this method uses an inflation method to expand the sealing airbag ring, avoiding the problem of poor sealing effect caused by the sealing strip losing elasticity when sealing.

The top of the movable seat 12 is provided with a card plate 7 extending to the inside of the card slot 6, and the outer wall of the threaded sleeve 10 is provided with a plurality of shifting blocks 11. When the movable seat 12 moves, it will drive the card plate 7 to move, and when the card plate 7 is inserted into the inside of the card slot 6, the cover plate 5 will be limited and fixed.

[0035] Specifically, the sealing assembly 9 includes a gasket 903 arranged on the inner wall of the shell 1, a plurality of slide grooves 909 opened on the inner wall of the shell 1, a pressure ring 901 installed on the bottom of the cover plate 5 and a slot 906 opened on the top of the shell 1, an insert ring 905 is inserted into the interior of the slot 906, and two sealing airbag rings 904 are arranged inside the slot 906, the bottom of the pressure ring 901 contacts the top of the movable ring 912, the diameter of the pressure ring 901 is the same as the diameter of the gasket 903, when the pressure ring 901 moves downward, it squeezes the compression airbag ring 902, and then the compression airbag ring 902 is compressed, and the air inside it will enter the air guide tube 908, the top of the insert ring 905 is connected to the bottom of the cover plate 5, so that the insert ring 905 can be driven to move when the cover plate 5 moves downward.

[0036] See also Figure 1-Figure 4A compressed air bag ring 902 is installed on the top of the gasket ring 903, and the outer wall of the compressed air bag ring 902 is provided with multiple air guide tubes 908 extending into the interior of the shell 1, and a movable ring 912 is provided on the top of the compressed air bag ring 902, and the air guide tube 908 is connected to an inflation tube 907 extending into the sealed air bag ring 904. When the air inside the compressed air bag ring 902 enters the air guide tube 908, the air will flow into the two sealed air bag rings 904 through the air guide tube 908, so that the sealed air bag rings 904 expand, and the slot 906 is in a ring shape. The inner wall and the outer wall of the plug-in ring 905 are both in contact with the sealed air bag ring 904, so that the plug-in ring 905 can be inserted into the slot 906. At the same time, after the plug-in ring 905 and the sealed air bag ring 904 are in contact, the sealing performance between the cover plate 5 and the shell 1 can be improved.

[0037] See also Figure 1 , Figure 2 and Figure 5 A movable groove 14 is provided on one side of the movable seat 12, and a plurality of movable blocks 13 are arranged inside the movable groove 14, and one side of the movable block 13 is connected to the threaded sleeve 10, so that when the threaded sleeve 10 rotates, the movable block 13 can be driven to slide in the movable groove 14, and the threaded sleeve 10 can drive the movable seat 12 to move. The movable groove 14 is annular, and the movable block 13 is slidably connected to the movable groove 14. A positioning seat 2 is installed at the lower part of the shell 1, and a positioning groove 3 is provided on the positioning seat 2. A lithium battery body 4 is arranged in the positioning groove 3. The setting of the positioning groove 3 facilitates the placement of the lithium battery body 4 and improves the stability of the lithium battery body 4 after placement.

[0038] Embodiment 2:

[0039] On the basis of the above-mentioned embodiment one, after the compression airbag ring 902 is compressed, the air inside it will enter into the sealing airbag ring 904, causing the sealing airbag ring 904 to expand. However, when the cover plate 5 is removed, the pressure ring 901 no longer squeezes the compression airbag ring 902. At this time, the compression airbag ring 902 needs to be restored, but the speed of restoration is slow due to the elasticity of the compression airbag ring 902 itself. Therefore, the following structure is set to improve the restoration efficiency of the compression airbag ring 902.

[0040] See also Figure 2 and Figure 6A return spring 911 is fixed at the lower part of the inner part of the slide groove 909, and a slider 910 is connected to the top of the return spring 911. One side of the slider 910 is connected to the movable ring 912. When the movable ring 912 moves downward to squeeze the compression airbag ring 902, the movable ring 912 will drive the slider 910 to move downward, and make the slider 910 squeeze the return spring 911, so that the return spring 911 is compressed. When the subsequent compression ring 901 moves up and resets, it no longer applies pressure to the movable ring 912. At this time, the return spring 911 stretches and then pushes the slider 910 to move up and reset, and drives the movable ring 912 to move up and reset, and then drives the compressed airbag ring 902 to recover quickly, so that the air inside the sealed airbag ring 904 flows back to the compressed airbag ring 902.

[0041] The working principle of the utility model is as follows: first, the user can place the lithium battery body 4 in the shell 1, and then close the cover 5. When the cover 5 is installed on the shell 1, the insert ring 905 at the bottom of the cover 5 will be inserted into the slot 906, and the pressure ring 901 will first contact the movable ring 912. As the cover 5 moves downward, it will push the movable ring 912 to move downward, and the movable ring 912 will squeeze the compressed airbag ring 902. After the compressed airbag ring 902 is compressed, the air inside it enters the air guide tube 908, and the air then flows into the two sealed airbag rings 904 through the air guide tube 908, so that the sealed airbag ring 904 expands, and the sealed airbag ring 904 fits the inner wall and outer wall of the insert ring 905, thereby improving the sealing between the shell 1 and the cover 5, and preventing water vapor or dust from entering the shell 1 through the gap between the cover 5 and the shell 1.

[0042] Then the user rotates the threaded sleeve 10 on the threaded rod 8, so that the threaded sleeve 10 moves and drives the movable seat 12 to move. When the movable seat 12 moves, it drives the clamping plate 7 to move. When the clamping plate 7 is inserted into the clamping slot 6, it limits and fixes the cover plate 5 to prevent the cover plate 5 from moving.

[0043] Although an embodiment of the utility model has been shown and described, this specific embodiment is only an explanation of the utility model and is not a limitation of the utility model. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples.
