Description

Technical Field

[0001] This utility model belongs to the field of battery equipment technology, and specifically relates to an R6S battery that is leak-proof. Background Technology

[0002] The R6S battery is a common type of dry cell battery with specific dimensions and electrical properties. In the name R6S, "R" stands for "round battery," and "6" indicates the battery's size, which is similar to that of common AA batteries. The "S" may indicate a specific type or standard. The leak-proof R6S battery is a well-designed and stable zinc-manganese dry cell battery. Its key feature is the use of advanced leak-proof technology, ensuring that the battery will not leak during use or long-term storage.

[0003] Announcement No. "CN221226510U" discloses a leak-proof battery tab, comprising a main body, an insulating sheet fixedly connected to the top of the main body, a tab body slidably connected inside the insulating sheet, a barrier block fixedly connected to the top of the main body, rubber rings fixedly connected to the bottom of both sides of the tab body, an explosion-proof layer fixedly connected to the bottom of the rubber rings, a nickel layer fixedly connected to the bottom of the explosion-proof layer, a copper layer fixedly connected to the bottom of the nickel layer, an alloy layer fixedly connected to the bottom of the copper layer, and a polymer layer fixedly connected to the bottom of the alloy layer. This leak-proof battery tab achieves corrosion resistance and is not easily corroded by electrolytes, while also providing good sealing at the connection points of the battery tab, thereby reducing the erosion of the tab surface by internal battery liquid and improving the lifespan of the tab.

[0004] While the aforementioned utility model achieves corrosion resistance and resistance to electrolyte erosion of the battery tabs, and provides good sealing of the connection parts of the battery tabs, thereby reducing the erosion of the tab surface by the internal liquid and improving the service life of the tabs, the battery generates a certain amount of heat during charging and discharging, causing the battery cell to expand slightly. The pressure inside the battery casing will gradually increase, leading to battery casing rupture or leakage, which in turn causes safety issues. Moreover, external impacts, such as drops or impacts, will directly cause physical damage to the battery casing and battery cell. Once the battery cell is damaged, the electrolyte inside will leak out, causing battery leakage. Utility Model Content

[0005] In response to the problems mentioned in the background art, the purpose of this utility model is to provide a leak-proof R6S battery to solve the problem that the battery generates a certain amount of heat during charging and discharging, which causes the battery cell to expand slightly. The pressure inside the battery casing will gradually increase, leading to the battery casing cracking or leakage, which in turn causes safety problems. Moreover, when subjected to external impacts, such as drops or impacts, the battery casing and battery cell will be directly physically damaged. Once the battery cell is damaged, the electrolyte inside will leak out, causing the battery leakage problem.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A leak-proof R6S battery includes a battery casing and a battery cell. The battery cell is housed inside the battery casing. A connecting piece is fixedly connected to the bottom of the battery casing and is in contact with the battery cell. A carbon rod is fixedly connected to the top of the battery cell. A positive electrode cap is fixedly connected to the top of the battery casing and is in contact with the carbon rod. A buffer plate is slidably provided inside the battery casing. Buffer components are symmetrically arranged in a circular array between the buffer plate and the positive electrode cap.

[0008] The buffer assembly includes a buffer seat, a first limiting post, a second limiting post, an internal hole, and a first buffer spring. Buffer grooves are symmetrically arranged in a circular array at the top of the buffer plate and the bottom of the positive electrode cap. A buffer seat is fixedly connected inside each buffer groove. A first limiting post is fixedly connected to one end of the buffer seat on the buffer plate, and an internal hole is formed at the other end of the first limiting post. A first buffer spring is fixedly connected to the bottom of the internal hole, and a second limiting post is fixedly connected to the other end of the first buffer spring. The second limiting post is slidably connected to the internal hole and is fixedly connected to the buffer seat on the positive electrode cap. A second buffer spring is sleeved on the outside of the first and second limiting posts, with its two ends fixedly connected to the opposite ends of the buffer seat. This assembly effectively absorbs and disperses the stress generated during battery charging and discharging, preventing the battery cell from deforming or being damaged due to excessive force. Furthermore, it acts as a shock absorber when the battery is subjected to external impact or vibration, protecting the battery cell from damage.

[0009] As a preferred technical solution, the battery casing has guide grooves symmetrically arranged in a ring-shaped array inside, and guide blocks are symmetrically fixedly connected to the outer wall of the buffer plate in a ring-shaped array. The guide blocks and guide grooves are slidably connected. The tight fit between the guide blocks and guide grooves can effectively reduce the vibration and shaking of the buffer plate during movement and improve stability.

[0010] As a preferred technical solution, a buffer pad is glued to the bottom of the buffer plate. The buffer pad is made of soft rubber, which can effectively absorb the impact and vibration of the battery during transportation, installation and use, thereby preventing the battery cell from being damaged by these external factors. It can also disperse and alleviate the internal stress generated by the battery during charging and discharging, protecting the battery cell from damage.

[0011] As a preferred technical solution, the inner wall of the battery casing is symmetrically and equidistantly connected with fixing rings, and reinforcing columns are fixedly connected between the fixing rings. Reinforcing rings are fixedly connected between the reinforcing columns. The reinforcing columns and reinforcing rings are arranged in a ring shape and equidistantly, which improves the thickness and rigidity of the battery casing and significantly improves its resistance to compression. When subjected to external extrusion pressure, the reinforcing rings and reinforcing columns can effectively disperse and resist these forces, ensuring that the battery maintains its integrity when subjected to extrusion pressure.

[0012] As a preferred technical solution, a protective pad is glued to one side of the reinforcing ring. The protective pad is attached to the outer wall of the battery cell. The protective pad is made of polyethylene terephthalate, which can effectively isolate the battery cell from other metal components and prevent short circuits and electrolyte leakage.

[0013] In summary, the present invention has the following main advantages:

[0014] First, in this utility model, when the positive cap at one end of the battery casing is subjected to an external impact, the buffer plate causes the second limiting post to slide inside the built-in hole of the first limiting post. The second limiting post presses against the first buffer spring, and the first and second buffer springs are compressed to absorb and disperse the impact force. This can effectively absorb and disperse the stress generated by the battery during charging and discharging, prevent the battery cell from deforming or being damaged due to excessive force, and also play a shock-absorbing role when the battery is subjected to external impact or vibration, protecting the battery cell from damage.

[0015] Secondly, in this utility model, when the battery casing is subjected to external compression, the fixed ring, reinforcing column, and reinforcing ring can resist the external extrusion force. Moreover, the protective pad can effectively isolate the battery cell from other metal parts, prevent short circuits and electrolyte leakage, improve the thickness and rigidity of the battery casing, and significantly improve its extrusion resistance. When subjected to external extrusion force, the reinforcing ring and reinforcing column can effectively disperse and resist these forces, thereby preventing the battery casing from deforming and protecting the various components inside the battery from damage due to deformation.

[0022] Example

[0023] refer to Figures 1 to 5 The R6S battery with leak-proof design described in this embodiment includes a battery casing 1 and a battery cell 4. The battery cell 4 is disposed inside the battery casing 1. A connecting piece 3 is fixedly connected to the bottom of the battery casing 1, and the connecting piece 3 is in contact with the battery cell 4. A carbon rod 5 is fixedly connected to the top of the battery cell 4. A positive electrode cap 2 is fixedly connected to the top of the battery casing 1, and the carbon rod 5 is in contact with the positive electrode cap 2. A buffer plate 6 is slidably disposed inside the battery casing 1. A buffer assembly 14 is symmetrically disposed between the buffer plate 6 and the positive electrode cap 2 through a circular circumferential array.

[0024] The buffer assembly 14 includes a buffer seat 141, a first limiting post 142, a second limiting post 143, an internal hole 144, and a first buffer spring 145. Buffer grooves 13 are symmetrically arranged in a circular array on the top of the buffer plate 6 and the bottom of the positive electrode cap 2. A buffer seat 141 is fixedly connected inside each buffer groove 13. One end of the buffer seat 141 on the buffer plate 6 is fixedly connected to the first limiting post 142, and the other end of the first limiting post 142 has an internal hole 144. A first buffer spring 145 is fixedly connected to the bottom of the internal hole 144, and the other end of the first buffer spring 145 is fixedly connected to the second limiting post 143. The second limiting post 143 is connected to the internal hole 144. The interior of the hole 144 is slidably connected. The second limiting post 143 is fixedly connected to the buffer seat 141 on the positive electrode cap 2. A second buffer spring 15 is sleeved on the outside of the first limiting post 142 and the second limiting post 143. The two ends of the second buffer spring 15 are fixedly connected to the opposite ends of the buffer seat 141, respectively. When the positive electrode cap 2 at one end of the battery casing 1 is subjected to an external impact, the buffer plate 6 causes the second limiting post 143 to slide inside the internal hole 144 of the first limiting post 142. The second limiting post 143 presses against the first buffer spring 145, and the first buffer spring 145 and the second buffer spring 15 are compressed to absorb and disperse the impact force.

[0025] refer to Figure 3 The battery casing 1 has guide grooves 8 symmetrically arranged in a ring-shaped array inside. The outer wall of the buffer plate 6 is symmetrically fixed with guide blocks 7 in a ring-shaped array. The guide blocks 7 and the guide grooves 8 are slidably connected. When the buffer plate 6 moves, the buffer plate 6 drives the guide blocks 7 to slide inside the guide grooves 8.

[0026] refer to Figure 3 The bottom of the buffer plate 6 is glued with a buffer pad 16. The buffer pad 16 is made of soft rubber. The buffer pad 16 can effectively absorb the impact and vibration of the battery during transportation, installation and use, thereby preventing the battery cell 4 from being damaged by these external factors. It can also disperse and alleviate the internal stress generated by the battery during charging and discharging, protecting the battery cell 4 from damage.

[0027] refer to Figure 4 The inner wall of the battery casing 1 is symmetrically and equidistantly connected with fixing rings 9, and reinforcing columns 10 are fixedly connected between the fixing rings 9. Reinforcing rings 11 are fixedly connected between the reinforcing columns 10. The reinforcing columns 10 and reinforcing rings 11 are arranged in a ring shape and equidistantly. The fixing rings 9 and reinforcing columns 10 improve the thickness and rigidity of the battery casing 1, and significantly improve its resistance to compression. When subjected to external compression, the reinforcing rings 11 and reinforcing columns 10 can effectively disperse and resist these forces, and ensure that the battery maintains its integrity when subjected to compression.

[0028] refer to Figure 4A protective pad 12 is glued to one side of the reinforcing ring 11. The protective pad 12 is attached to the outer wall of the battery cell 4. The protective pad 12 is made of polyethylene terephthalate. The protective pad 12 can effectively isolate the battery cell 4 from other metal parts to prevent short circuits and electrolyte leakage.

[0029] Operating principle and advantages: First, when the positive cap 2 at one end of the battery casing 1 is subjected to external impact, the buffer plate 6 causes the second limiting post 143 to slide inside the built-in hole 144 of the first limiting post 142. The second limiting post 143 presses against the first buffer spring 145, and the first buffer spring 145 and the second buffer spring 15 are compressed to absorb and disperse the impact force. Moreover, when the battery casing 1 is squeezed from the outside, the fixed ring 9, the reinforcing post 10 and the reinforcing ring 11 can resist the external squeezing force. Furthermore, the protective pad 12 can effectively isolate the battery cell 4 from other metal parts to prevent short circuits and electrolyte leakage.

[0030] This invention can effectively absorb and disperse the stress generated during the charging and discharging process of the battery, preventing the battery cell 4 from deforming or being damaged due to excessive force. Moreover, it can play a shock-absorbing role when the battery is subjected to external impact or vibration, protecting the battery cell 4 from damage.
