[0002] Lithium 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. Lithium batteries were first used in cardiac pacemakers. The advantages of lithium batteries, such as extremely low self-discharge rate and gentle discharge voltage, enable implanted pacemakers to operate for long periods of time without recharging. Lithium batteries generally have a nominal voltage higher than 3.0 volts, making them more suitable as power sources for integrated circuits. Manganese dioxide batteries are widely used in calculators, digital cameras, and watches.

For example, "connected" can mean a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be internal communication between two components. Those skilled in the art will be able to understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0023] See also Figure 1-6 The utility model provides an embodiment of a cylindrical lithium battery, comprising a lithium battery body 1, an outer protective frame 2 is mounted on the outer wall of the lithium battery body 1, and the outer protective frame 2 can provide external wrapping protection for the internal lithium battery body 1, thereby improving the use effect;

[0024] A side positioning slide 8 is fixedly mounted on the outer wall of one side of the protective frame 2. Two sets of positioning holes 9 are provided at the upper and lower ends of the side positioning slide 8. The spacing between the two positioning holes 9 at the upper end is greater than the spacing between the two positioning holes 9 at the lower end. For details, please refer to the attached manual. Figure 6 As shown, this structural design can form a size distance difference between the holes, so that during the later positioning sliding, the upper positioning structure can be effectively prevented from being inserted into the lower positioning hole, thereby avoiding positioning locking and improving the use effect;

[0025] A side positioning slot 3 adapted to the side positioning slide 8 is fixedly installed on the outer wall on the other side of the outer protective frame 2. Telescopic holes 4 corresponding to the positions of the positioning holes 9 are opened at the upper and lower ends of the side positioning slot 3. A positioning plug-in column 5 is inserted in each telescopic hole 4. The front end face of the positioning plug-in column 5 is designed with an arc-shaped edge, which can improve the smoothness during contact sliding and reduce sliding resistance.

[0026] Furthermore, the positioning plug-in column 5 is slidably connected to the telescopic hole 4, and a rear gasket 6 is fixedly installed at the tail end of the positioning plug-in column 5;

[0027] Furthermore, a return spring 7 is fixedly mounted on the outer wall of the rear gasket 6 away from the positioning plug-in column 5, and the tail end of the return spring 7 is fixedly mounted on the inner wall of the bottom end of the telescopic hole 4;

[0028] According to the above structure, when the cylindrical lithium battery A of the present invention is assembled and connected with another cylindrical lithium battery B, the side positioning slide plate 8 of the cylindrical lithium battery A can slide from top to bottom into the side positioning slide groove 3 connected to the cylindrical lithium battery B;

[0029] When the side positioning slide plate 8 is sliding in, when the bottom end of the side positioning slide plate 8 contacts the positioning plug-in column 5 at the upper end, the positioning plug-in column 5 at the upper end can be manually pressed to retract it into the telescopic hole 4 to ensure that the side positioning slide plate 8 can smoothly pass through the positioning plug-in column 5 at the upper end. At the same time, the retracted positioning plug-in column 5 will compress the return spring 7 at the tail end through the rear gasket 6, so that the return spring 7 is always in a compressed state.

[0030] As the side positioning slide plate 8 continues to slide in, the bottom surface of the side positioning slide plate 8 will contact the positioning plug-in column 5 at the lower end. At this time, the positioning plug-in column 5 at the lower end is manually pressed again to retract it into the telescopic hole 4 at the lower end to ensure that the side positioning slide plate 8 passes smoothly.

[0031] Then, the side positioning slide plate 8 is slid downward for a distance. When the positioning hole 9 at the lower end of the side positioning slide plate 8 and the positioning plug post 5 at the lower end are at the same horizontal plane, the positioning plug post 5 at the lower end will automatically extend under the drive of the return spring 7 in the compressed state, so that the positioning plug post 5 at the lower end can be inserted into the positioning hole 9 at the lower end of the side positioning slide plate 8.

[0032] Similarly, when the positioning hole 9 at the lower end of the side positioning slide 8 and the positioning plug-in column 5 at the lower end are in the same horizontal plane, and the positioning plug-in column 5 at the upper end and the positioning hole 9 at the upper end are synchronously in the same horizontal plane, at this time, the several positioning plug-in columns 5 set at the upper and lower ends can be respectively inserted into the corresponding positioning holes 9, thereby completing the assembly and use effect between the two cylindrical lithium batteries. In actual use, through the coordinated use of the above-mentioned structure, the two lithium batteries have the technical characteristics of quick connection and assembly, and can complete the rapid sliding assembly work, ensuring the normal combination and use effect of the square cylindrical lithium batteries. It has the use characteristics of quick positioning and assembly, and solves the technical problem that the existing square cylindrical lithium battery structure is not convenient enough when assembling and connecting with each other, thereby affecting the combined use.

[0033] In this embodiment, both sides of the upper surface of the outer protective frame 2 are provided with pole through holes 10 adapted to the lithium battery body 1, so that the pole through holes 10 provided can ensure the normal penetration of the electrode column of the lithium battery body 1, as shown in the attached manual. Figure 1 As shown, normal use is guaranteed.

[0034] In this embodiment, in order to improve the connection protection between the outer protective frame 1 and the lithium battery, a protective silicone strip is provided between the outer protective frame 2 and the lithium battery body 1. The protective silicone strip is fixed on the inner wall of the outer protective frame 2 by glue (not shown in the figure). The protective silicone strip can provide flexible buffering protection for the outer wall of the lithium battery, avoid hard contact damage, and better protect the lithium battery.

[0035] Working principle: When it is necessary to combine the square cylindrical lithium batteries of the present invention, several lithium battery structures of the present invention can be prepared. When assembling and connecting, the side positioning slide 8 of the cylindrical lithium battery A can slide from top to bottom into the side positioning slide 3 connected to another cylindrical lithium battery B;

[0036] When the side positioning slide plate 8 is sliding in, when the bottom end of the side positioning slide plate 8 contacts the positioning plug-in column 5 at the upper end, the positioning plug-in column 5 at the upper end can be manually pressed to retract it into the telescopic hole 4 to ensure that the side positioning slide plate 8 can smoothly pass through the positioning plug-in column 5 at the upper end. At the same time, the retracted positioning plug-in column 5 will compress the return spring 7 at the tail end through the rear gasket 6, so that the return spring 7 is always in a compressed state.

[0037] As the side positioning slide plate 8 continues to slide downward, the bottom surface of the side positioning slide plate 8 will contact the positioning plug-in column 5 at the lower end. At this time, the positioning plug-in column 5 at the lower end is manually pressed again to retract it into the telescopic hole 4 at the lower end to ensure that the side positioning slide plate 8 passes smoothly.

[0038] Then, the side positioning slide plate 8 is slid downward for a short distance. When the positioning hole 9 at the lower end of the side positioning slide plate 8 and the positioning plug post 5 at the lower end are at the same horizontal plane, the positioning plug post 5 at the lower end will automatically extend under the drive of the return spring 7 in the compressed state, so that the positioning plug post 5 at the lower end can be inserted into the positioning hole 9 at the lower end of the side positioning slide plate 8.

[0039] Similarly, when the positioning hole 9 at the lower end of the side positioning slide 8 and the positioning plug-in column 5 at the lower end are in the same horizontal plane, and the positioning plug-in column 5 at the upper end and the positioning hole 9 at the upper end are synchronously in the same horizontal plane, at this time, the plurality of positioning plug-in columns 5 provided at the upper and lower ends can be respectively inserted into the corresponding positioning holes 9, thereby completing the assembly effect between the two cylindrical lithium batteries, and at this time, the two lithium batteries are horizontally flush;

[0040] In actual use, the above structure is used in conjunction with each other, so that the two lithium batteries have the technical characteristics of quick connection and assembly, and the quick sliding assembly work between the lithium batteries can be completed, ensuring the normal combination and use effect of the square cylindrical lithium batteries. It has the characteristics of quick positioning and assembly, and solves the technical problem that the existing square cylindrical lithium battery structure is not convenient when assembling and connecting each other, thereby affecting the combined use;

[0041] In addition, there is a certain spacing size difference between the upper and lower insertion structures and the positioning hole structures of the utility model. This structural design can effectively avoid the situation in which the bottom hole structure automatically pops out and causes the plug-in structure to be locked when passing through the upper plug-in structure during the sliding process from top to bottom, thereby avoiding the phenomenon of mismatched positioning and locking, and improving the adaptability and use effect of the overall structure.

[0042] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
