[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0020] Referring to Figures 1-4 , a button cell with high safety includes a battery body 1, and is characterized in that: a positioning mechanism is installed on the battery body 1. By providing a positioning mechanism, when the button cells are assembled and installed, it can position the button cells to prevent the button cells from shifting and causing poor contact. A protection mechanism is installed on the battery body 1. By providing a protection mechanism, it can protect the button cells, which is beneficial to the use of the button cells. A pressure relief mechanism is installed on the battery body 1. By providing a pressure relief mechanism, when the internal pressure of the button cell rises to a dangerous level, the pressure relief mechanism will automatically open to release the gas generated inside, so as to prevent the button cell from exploding or cracking due to excessive pressure. The protection mechanism includes a protection ring 32, and the protection ring 32 is fixedly installed on the battery body 1, and a protection strip 31 is fixedly installed on the protection ring 32.

[0021] Specifically, both the protective ring 32 and the protective strip 31 are made of silica gel. Silica gel is a glassy substance composed of silicon dioxide molecules, with high flexibility and elasticity. This enables silica gel to effectively absorb and disperse impact force when subjected to impact, reducing damage to products or equipment. The molecular structure of silica gel is highly porous and conductive, which also provides it with good sound absorption, heat insulation, and shockproof properties, further enhancing its buffering effect. At the same time, silica gel also has excellent wear resistance. By providing the protective ring 32 and the protective strip 31 made of silica gel, it is convenient to protect the surface of the battery body 1, facilitating the long-term use of the battery.

[0022] Furthermore, the pressure relief mechanism includes a pipe 21. The pipe 21 is fixedly installed on the battery body 1. The pipe 21 is a cylindrical pipe, and the pipe 21 communicates with the inner wall of the battery body 1. An insert sleeve 22 is fixedly installed on the inner wall of the pipe 21. The insert sleeve 22 is circular in shape. By providing the insert sleeve 22, it is convenient to receive the insertion of the sphere 23, thereby achieving the purpose of sealing the pipe 21. An installation rod 25 is fixedly installed on the inner wall of the pipe 21. The installation rod 25 is square in shape. The installation of the installation rod 25 facilitates the installation of the spring 26. The top end of the installation rod 25 is fixedly installed with a spring 26. By providing the spring 26, it is convenient to receive the installation of the sliding rod 24 and also to apply a force to the sliding rod 24. One end of the spring 26 is fixedly installed with a sliding rod 24. The cross-sectional shape of the sliding rod 24 is T-shaped. The setting of the sliding rod 24 facilitates the installation of the sphere 23. The bottom end of the sliding rod 24 penetrates through the installation rod 25 and is fixedly installed with a sphere 23. The sphere 23 is used to be inserted into the insert sleeve 22. When the internal pressure of the button battery rises to a dangerous level, the pressure will squeeze the sphere 23, and the sphere 23 will drive the sliding rod 24 to slide along the through hole of the installation rod 25. At this time, the sphere 23 will leave the insert sleeve 22, thereby achieving the purpose of opening the pipe 21, and the air pressure will be released along the pipe 21 to prevent the button battery from exploding or bursting due to excessive pressure.

[0023] Finally, the positioning mechanism includes insertion blocks 41. The insertion blocks 41 are fixedly installed on the battery body 1. The number of insertion blocks 41 is four. The insertion blocks 41 are used to be inserted into the insertion slots 42. The bottom end of the battery body 1 is provided with insertion slots 42. The number of insertion slots 42 is four. The insertion slots 42 are cylindrical slots. The setting of the insertion slots 42 is used to receive the insertion of the insertion blocks 41. When installing the button battery, insert the insertion blocks 41 into the insertion slots 42 to achieve the purpose of positioning between the button batteries and avoid the occurrence of poor contact caused by misalignment between the button batteries.

[0024] Working mode: When working, by providing a pressure relief mechanism, when the internal pressure of the button battery rises to a dangerous level, the pressure will squeeze the ball 23, and the ball 23 will drive the slide bar 24 to slide along the through hole of the mounting rod 25. At this time, the ball 23 will leave the socket 22, thereby achieving the purpose of opening the pipe 21, and the air pressure will be released along the pipe 21 to prevent the button battery from exploding or rupturing due to excessive pressure. After the pressure relief is completed, the ball 23 will be reinserted into the socket 22 under the action of the spring 26.

[0025] When installing the button type battery, the insert block 41 is inserted into the slot 42 to achieve the purpose of positioning the button type batteries and avoid the occurrence of poor contact caused by misalignment of the button type batteries.

[0026] By providing a protective ring 32 and a protective strip 31 made of silicone, both the protective ring 32 and the protective strip 31 are made of silicone. Silicone is a glass-like substance composed of silicon dioxide molecules, which has high softness and elasticity, which enables silicone to effectively absorb and disperse impact force when impacted, thereby reducing damage to products or equipment. The molecular structure of silicone is highly porous and conductive, which also provides it with good sound absorption, heat insulation and shockproof properties, further enhancing its buffering effect. At the same time, silicone also has excellent wear resistance. By providing a protective ring 32 and a protective strip 31 made of silicone, it is convenient to protect the surface of the battery body 1, which is beneficial to the long-term use of the battery.

[0027] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
