Description

Technical Field

[0001] This utility model belongs to the field of battery technology, and specifically relates to a sealing ring structure for preventing battery leakage. Background Technology

[0002] Batteries generate electrical energy through internal chemical reactions or physical processes. Chemical batteries, especially chemical power sources, focus on converting chemical energy into electrical energy. Their core components include positive and negative electrochemical active electrodes and chemical substances that act as a medium for conduction, such as an electrolyte. When the battery is connected to an external device, its internal chemical energy is converted to provide electrical energy.

[0003] For example, Chinese patent CN217955900U discloses an energy-saving battery with a sealing ring to prevent leakage, including a zinc cylinder, a carbon rod, and an electrolyte. One end of the carbon rod is inserted into the inside of the zinc cylinder and connected to the electrolyte filled inside the zinc cylinder. The other end of the carbon rod extends out of the zinc cylinder and is fitted with a copper cap. A sealing ring connected to the carbon rod is provided on the lower side of the copper cap. The sealing ring is located at the top of the zinc cylinder. An outer shell is provided on the outside of the zinc cylinder, and a cover plate connected to the copper cap is provided on the upper side of the outer shell.

[0004] The aforementioned patent addresses the issue that battery leakage can occur during use due to excessive temperature or over-discharge. Furthermore, even during storage, a small leakage current can still be generated at the input terminal when there is no output. Over the long term, this leakage current accumulates and can account for a considerable proportion of the battery's total capacity, significantly reducing its lifespan. However, existing batteries still have some shortcomings that require improvement. The sealing structure is relatively simple, and once the sealing ring ages, the electrolyte solution inside the battery may leak out through tiny gaps in the connection. This not only pollutes the environment around the battery but may also cause short circuits and other safety hazards, seriously threatening the safe operation of the battery and even the entire device.

The side of the first sealing component away from the connecting plate is fitted with a second sealing component. The second sealing component is fixedly connected to the shell cover.

A carbon rod 2 is fixedly connected to the middle of the fixing disk 3. One side of the carbon rod 2 extends into the interior of the housing 1. A housing cover 5 is fixedly connected to one side of the housing 1. A sealing mechanism 4 is provided between the housing cover 5 and the fixing disk 3. The sealing mechanism 4 includes a connecting disk 41, which is mounted on the fixing disk 3. A telescopic member 45 is provided on the side of the connecting disk 41 away from the fixing disk 3, and multiple telescopic members 45 are provided. The top ends of the multiple telescopic components 45 are fixedly connected to a first sealing element 42. The side of the first sealing element 42 away from the connecting plate 41 is fitted with a second sealing element 43. The second sealing element 43 is fixedly connected to the shell cover 5. The first sealing element 42 and the second sealing element 43 are both sleeved on the carbon rod 2. By setting the first sealing element 42 and the second sealing element 43, the multiple sealing elements can more effectively prevent the leakage of electrolyte solution. This can effectively avoid the problem of short circuit caused by leakage of electrolyte solution, thereby significantly improving the safety of the battery.

[0025] refer to Figure 1 A copper cap 6 is fixedly connected to one side of the shell cover 5, and one side of the carbon rod 2 is connected to the inside of the copper cap 6; by setting the copper cap 6 and connecting the copper cap 6 to the carbon rod 2, the current can be transmitted stably.

[0026] refer to Figure 2-3 A docking block 31 is fixedly connected to one side of the fixed disk 3. A docking hole 44 is opened inside the connecting disk 41. The docking block 31 is connected inside the docking hole 44, and both are hexagonal structures. By fixing the docking block 31 on the fixed disk 3 and opening the docking hole 44 on the connecting disk 41, the docking block 31 is connected to the docking hole 44, so that the connecting disk 41 can be installed on the fixed disk 3.

[0027] refer to Figure 3-4 The telescopic component 45 includes a spring 451, which is fixedly connected to the top of the fixed disk 3. Multiple springs 451 are provided. The top of each spring 451 is fixedly connected to the bottom of the first sealing component 42. A guide rod 452 is slidably connected to the inner side of each spring 451. The guide rod 452 is fixedly connected to the bottom of the first sealing component 42, and one side of the guide rod 452 is slidably connected to the fixed disk 3. By providing the spring 451, even if the first sealing component 42 ages to a certain extent during use, the spring 451 can compensate for this and maintain a tight fit with the second sealing component 43, effectively preventing leakage of the electrolyte solution. The guide rod 452 ensures stable movement of the first sealing component 42, preventing positional deviation and facilitating a reliable connection between the first sealing component 42 and the second sealing component 43.

[0028] refer to Figure 3-4 The top end of the first sealing element 42 is fixedly connected to a positioning ring 47, and the bottom end of the second sealing element 43 is provided with a positioning groove 46. The positioning ring 47 is fitted and connected to the positioning groove 46. By setting the positioning ring 47 and the positioning groove 46, the contact area between the first sealing element 42 and the second sealing element 43 is increased, which is conducive to the two fitting together.

The sealing block 8 is fixedly connected to the bottom end of the cover 5. A positioning rod 9 is fixedly connected to the inside of the sealing groove 7, and a positioning hole 10 is provided at the bottom end of the sealing block 8. The positioning rod 9 is movably connected to the positioning hole 10. By setting the sealing groove 7 and the sealing block 8, the housing 1 and the cover 5 are kept sealed, making it less prone to leakage and further improving the battery's anti-leakage performance. By setting multiple positioning rods 9 and positioning holes 10, the two can be combined more quickly and accurately, which also greatly enhances the reliability and stability of the connection.

[0030] Operating principle and advantages: By installing a first seal 42 and a second seal 43 inside the housing 1, the multiple seals can more effectively prevent electrolyte solution leakage, thus avoiding the problem of short circuits caused by electrolyte solution leakage. During use, the first seal 42 and the second seal 43 will age to a certain extent. Through the compensation effect of the spring 451, the two will maintain a tight fit, ensuring the normal sealing structure and effectively preventing electrolyte solution leakage. The guide rod 452 is set to make the first seal 42 move stably and avoid positional deviation, thereby facilitating the reliable connection between the first seal 42 and the second seal 43. The sealing groove 7 and the sealing block 8 are set to keep the housing 1 and the cover 5 sealed, making it less prone to leakage and further improving the battery's anti-leakage performance. By setting multiple positioning rods 9 and positioning holes 10, the two can be combined more quickly and accurately, which also greatly enhances the reliability and stability of the connection.
