[0026] It should be noted that when a component is referred to as being "fixed to" another component, it can be directly on the other component or there can also be an intermediate component. When a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intermediate component at the same time.
[0027] Unless otherwise defined, all technical and scientific terms used in the present invention have the same meaning as commonly understood by those skilled in the technical field to which the present utility model belongs. The terms used in the present utility model in the specification are only for the purpose of describing specific embodiments, and are not intended to limit the present utility model. The term "and / or" used in the present utility model includes any and all combinations of one or more of the related listed items.
[0028] Next, in conjunction with the accompanying drawings, some embodiments of the present utility model will be described in detail. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.
[0029] In the prior art, the strength of the explosion-proof valve matrix of the battery is insufficient, resulting in excessive stress concentration in the explosion-proof valve matrix and the scoring area, and the explosion-proof valve abnormally opens during normal use, ultimately leading to the failure of the battery pack.
[0030] Reference Figures 1 to 2 , the present utility model provides a matrix 1 for an explosion-proof valve 5. The matrix 1 is in a sheet structure, and a strengthening structure is sequentially arranged from the center to the edge of the matrix 1. The periphery of the edge of the matrix 1 is connected to the periphery of the first scoring area 2 close to the center edge of the matrix 1, and the first scoring area 2 is in an annular shape.
[0031] Specifically, the matrix 1 of the explosion-proof valve 5 adopts a unique sheet structure, and the overall structural strength and compressive performance are significantly improved through the carefully designed strengthening structure.
[0032] First of all, the core of the matrix 1 adopts a sheet structure, which enables the matrix 1 to have good plasticity and processability while ensuring strength. Through the design of the sheet structure, the matrix 1 can flexibly adapt to various complex installation environments and dimensional requirements, providing a basis for the wide application of the explosion-proof valve 5.
[0033] Secondly, in the area from the center to the edge of the substrate 1, strengthening structures are sequentially arranged. These strengthening structures not only enhance the overall strength of the substrate 1, but also enable the substrate 1 to more evenly disperse the force to the entire structure when under pressure. Such a design effectively improves the pressure-bearing capacity and service life of the explosion-proof valve 5.
[0034] Furthermore, the periphery of the edge of the substrate 1 is connected to the periphery of the first scoring area 2 close to the center edge of the substrate 1. The first scoring area 2 is annular. Such a design enables the explosion-proof valve 5 to rupture orderly along the first scoring area 2 when the pressure exceeds the preset pressure, thereby releasing the internal pressure and preventing the equipment from exploding or rupturing. This rupture method not only ensures the safety of the explosion-proof valve 5, but also avoids the splashing and spreading of fragments, further improving the use safety.
[0035] The substrate 1 of the explosion-proof valve 5 provided by the present utility model significantly improves the overall strength and compressive performance of the substrate 1 through the combination of the sheet structure and the strengthening structure. At the same time, through the design of the first scoring area 2, the orderly rupture of the explosion-proof valve 5 when the pressure exceeds the preset pressure is realized, effectively preventing the equipment from exploding or rupturing. In addition, the substrate 1 also has good plasticity and processability, and can adapt to various complex installation environments and size requirements, providing strong support for the wide application of the explosion-proof valve 5.
[0036] In one embodiment, the substrate 1 is an annular sheet structure, the strengthening structure is a reticular ring, and there is a gap between the edge of the substrate 1 and the reticular ring edge of the strengthening structure. The relationship between the gap and the radius of the substrate 1 is 1 / 6*r ≤ d ≤ 1 / 4*r, where d is the gap and r is the radius of the substrate 1.
[0037] Specifically, the substrate 1 adopts an annular sheet structure, which not only improves the overall stability and strength of the structure, but also provides a basis for its load-bearing function. More importantly, a reticular ring-shaped strengthening structure is introduced in this design. This structure provides additional support and enhancement for the substrate 1, enabling the entire structure to maintain excellent performance in the face of various pressures and impacts.
[0038] It is particularly noteworthy that there is a specific gap between the edge of the substrate 1 and the reticular ring edge of the strengthening structure. The size of this gap is not set randomly, but there is an exact mathematical relationship with the radius of the substrate 1, that is, the relationship between the gap d and the radius r of the substrate 1 is 1 / 6*r ≤ d ≤ 1 / 4*r. This design cleverly balances the structural strength and material usage efficiency, ensuring that the structure can effectively transfer and disperse the force when under pressure, while avoiding material waste and excessive cost problems.
[0039] This design enables the substrate 1 to achieve comprehensive strengthening of the structure through the reticular annular layout of the strengthening structure while maintaining the annular sheet structure. This allows the entire structure to maintain good stability when facing forces from all directions. The precise relationship between the spacing d and the radius r of the substrate 1 ensures the maximization of structural strength. When the spacing is too small, although the strength of the structure can be enhanced, it may also lead to excessive material use and increased costs; while when the spacing is too large, it may result in a decrease in structural strength and the inability to withstand large pressures. Therefore, by setting a reasonable spacing range, this design not only maintains the structural strength but also ensures the maximization of cost-effectiveness. Finally, this design also has good plasticity and processability, and can be adjusted and optimized according to specific application scenarios and requirements to meet different usage needs.
[0040] In one embodiment, the strengthening structure includes a central reinforcing rib 1-1, an arc-shaped cross reinforcing rib 1-2, and a straight reinforcing rib 1-3. The strengthening structure is sequentially provided with a central reinforcing rib 1-1, an arc-shaped cross reinforcing rib 1-2, and a straight reinforcing rib 1-3 from the center to the edge. The end of the central reinforcing rib 1-1 away from the center is connected to the end of the arc-shaped cross reinforcing rib 1-2 close to the center, and the end of the arc-shaped cross reinforcing rib 1-2 away from the center is connected to the end of the straight reinforcing rib 1-3 close to the center.
[0041] Specifically, the strengthening structure of the explosion-proof valve 5 is ingeniously constructed as a multi-layer and multi-form combination, aiming to provide an all-round strengthening effect from the center to the edge. This strengthening structure is mainly composed of a central reinforcing rib 1-1, an arc-shaped cross reinforcing rib 1-2, and a straight reinforcing rib 1-3. Each reinforcing rib is precisely laid out and designed according to its position and function.
[0042] First of all, the central reinforcing rib 1-1, as the core of the entire strengthening structure, is located at the center of the structure, providing strong support and stability for the entire structure. It can not only withstand the pressure from the central area 1-4 but also effectively disperse the pressure to the surrounding arc-shaped cross reinforcing ribs 1-2.
[0043] Then, the arc-shaped cross reinforcing rib 1-2 starts from the periphery of the central reinforcing rib 1-1 and extends to both sides at a certain angle, forming a cross-shaped structure. This design can significantly improve the strength of the structure while maintaining its beauty. One end of the arc-shaped cross reinforcing rib 1-2 is closely connected to the central reinforcing rib 1-1, and the other end is connected to the straight reinforcing rib 1-3, forming a smooth transition to ensure the continuity and efficiency of pressure transmission.
[0044] Finally, the straight reinforcing ribs 1-3 are located at the edge of the structure and are connected to the periphery of the arc-shaped cross reinforcing ribs 1-2. They extend along the edge of the structure, providing additional support and stability to the entire structure. The presence of the straight reinforcing ribs 1-3 can effectively resist external impacts and pressures, preventing deformation and damage to the structure.
[0045] Overall, this reinforced structure design can achieve all-round enhancement from the center to the edge, not only improving the strength and stability of the structure, but also ensuring the integrity and aesthetics of the structure. In practical applications, this reinforced structure can be widely used in equipment and products that need to withstand high pressure or high impact, such as explosion-proof valves 5, pressure vessels, etc., to ensure their safe and reliable operation under extreme conditions.
[0046] In one embodiment, the central reinforcing rib 1-1, the arc-shaped cross reinforcing rib 1-2, and the straight reinforcing rib 1-3 are integrally formed or composite formed with the base body 1.
[0047] Specifically, the central reinforcing rib 1-1, the arc-shaped cross reinforcing rib 1-2, and the straight reinforcing rib 1-3 of the above explosion-proof valve 5 are tightly combined with the base body 1 through an integrally formed or composite formed process, jointly constituting a solid framework of the explosion-proof valve 5. This structural design not only significantly improves the overall strength and stability of the explosion-proof valve 5, but also ensures the reliability and durability of the valve under extreme environments such as high pressure and high temperature.
[0048] The integrally formed technology is an advanced manufacturing process that fuses different materials or components into a whole at one time through conditions such as high temperature and high pressure. In the design of the explosion-proof valve 5, the central reinforcing rib 1-1, the arc-shaped cross reinforcing rib 1-2, and the straight reinforcing rib 1-3 are tightly combined with the base body 1 through the integrally formed technology to form a seamless integrated structure. This structure can effectively avoid problems such as loose connection and easy cracking that may be brought about by traditional welding or bonding methods, thereby greatly improving the safety and reliability of the explosion-proof valve 5.
[0049] Another alternative manufacturing method is the composite forming technology. In this technology, the central reinforcing rib 1-1, the arc-shaped cross reinforcing rib 1-2, and the straight reinforcing rib 1-3 and the base body 1 are made of different materials respectively, and then they are tightly combined together through special process methods. This composite forming technology can make full use of the advantages of different materials, such as high strength, high toughness, corrosion resistance, etc., thereby improving the overall performance of the explosion-proof valve 5. At the same time, the composite forming technology can also flexibly adjust the materials and thicknesses of each part to meet the usage requirements under different working conditions.
[0050] Whether it is integrally formed or compositely formed, the close combination of the reinforcing ribs and the base 1 enables the explosion-proof valve 5 to better withstand various internal and external pressures and stresses. In a high-pressure environment, the reinforcing ribs can effectively disperse and support the pressure, preventing the valve from deforming or breaking due to uneven force. At the same time, in a working environment with large temperature changes, the close combination between the reinforcing ribs and the base 1 can also reduce the impact of thermal stress on the valve, ensuring the long-term stable operation of the valve.
[0051] In summary, the design of the explosion-proof valve 5 in which the central reinforcement rib 1-1, the arc-shaped cross reinforcement rib 1-2 and the straight reinforcement rib 1-3 are tightly combined with the base 1 through the one-piece molding or composite molding technology not only improves the overall performance and reliability of the valve, but also provides a safer and more stable solution for various industrial applications.
[0052] In one embodiment, the central reinforcing rib 1 - 1 is in a circular ring shape, and a central area 1 - 4 is formed in the center of the ring. The central area 1 - 4 corresponds to the base body 1 as a closed area or an open area.
[0053] Specifically, the unique structure of the central reinforcement rib 1-1 of the explosion-proof valve 5 provides the valve with enhanced stability and durability. The central reinforcement rib 1-1 is presented in a circular ring shape, surrounding the center of the explosion-proof valve 5, forming a significant reinforcement area. The center of the ring further forms a central area 1-4, which can be a closed area or an open area according to specific design requirements.
[0054] When the central area 1-4 is a closed area, it forms a solid core, which enhances the pressure resistance of the explosion-proof valve 5 under high pressure. The closed central area 1-4 not only provides strong support for the explosion-proof valve 5, but also ensures the stability and sealing of the valve under extreme conditions.
[0055] On the other hand, if the central area 1-4 is designed as an open area, the explosion-proof valve 5 will have better flexibility and adaptability. The open central area 1-4 can allow the valve to undergo slight deformation when subjected to pressure changes, thereby alleviating the impact of pressure on the overall structure of the valve. This design is particularly suitable for applications that require frequent switching and withstand fluctuating pressures, such as steam exhaust systems in thermal power plants and emission control in sewage treatment plants.
[0056] Regardless of whether the central area 1-4 is closed or open, the annular design of the central reinforcement rib 1-1 provides uniform stress distribution for the explosion-proof valve 5. This means that when the pressure changes, the valve can be evenly stressed, reducing the risk of damage caused by stress concentration. This design also improves the durability and reliability of the explosion-proof valve 5 and extends its service life.
[0057] In summary, the circular ring design of the central reinforcing rib 1-1 and the different forms of the central area 1-4 provide a variety of design options for the explosion-proof valve 5. These innovative designs not only enhance the structural stability and durability of the explosion-proof valve 5, but also improve its ability to adapt to different working environments, providing a safer and more reliable solution for industrial applications.
[0058] In one embodiment, the central area 1-4 corresponds to the open area of the substrate 1, and the central area 1-4 is used as a liquid injection hole, and a sealing device is provided in the liquid injection hole.
[0059] Specifically, when the central area 1-4 of the base 1 of the explosion-proof valve 5 is designed as an opening area, this area is cleverly used as a liquid injection hole. This design not only adds new functions to the explosion-proof valve 5, but also further improves its safety and reliability.
[0060] The injection hole is an important part of the explosion-proof valve 5, which allows specific liquids or media to be injected into the valve when needed. For example, in some applications, it may be necessary to inject lubricating liquid into the valve through the injection hole to reduce friction and wear, or inject sealing liquid to enhance the sealing performance of the valve.
[0061] In order to ensure that the injection hole can remain closed when not in use to prevent liquid leakage or external impurities from entering, the design is also equipped with a special sealing device. This sealing device can be a sealing cover, sealing plug or other forms of sealing, which can effectively seal the injection hole and ensure the cleanliness and safety of the inside of the valve.
[0062] The design of the sealing device also takes into account the convenience of operation and durability. It usually adopts a structure that is easy to install and disassemble, so that users can operate it as needed. At the same time, the material of the sealing device is also carefully selected to ensure that it has good sealing performance and corrosion resistance, and can maintain long-term stability and reliability in various working environments.
[0063] During normal use of the explosion-proof valve 5, the combination of the injection hole and the sealing device provides a strong guarantee for the safe operation of the valve. When liquid needs to be injected, the user can easily open the sealing device and inject the required liquid into the valve through the injection hole. After the operation is completed, the sealing device is closed again to ensure the sealing and safety of the inside of the valve. This design not only improves the practicality of the explosion-proof valve 5, but also enhances its safety and reliability, enabling it to better adapt to various complex working environments.
[0064] In one embodiment, the central area 1 - 4 corresponds to the base body 1 as a closed area, the central area 1 - 4 is provided with a second scoring area, and the central area 1 - 4 and the second scoring area provided thereon form a second explosion-proof valve 5 .
[0065] Specifically, when the central area 1-4 of the matrix 1 of the explosion-proof valve 5 is designed as a closed area, a second scoring area is ingeniously arranged inside it. This innovative design not only enhances the functionality of the explosion-proof valve 5 but also further improves its safety performance.
[0066] As the core area of the explosion-proof valve 5, the closed design of the central area 1-4 ensures the stability and sealing performance of the valve under high-pressure environments. The second scoring area arranged within the central area 1-4 forms an independent pressure release mechanism, namely the second explosion-proof valve 5. The existence of this second explosion-proof valve 5 endows the entire explosion-proof valve 5 system with dual safety guarantees.
[0067] The design of the second scoring area is similar to that of the main scoring area, but its position and size are precisely calculated to ensure that it can rupture prior to the main scoring area under specific pressure conditions. When the internal pressure of the system exceeds the preset safety threshold, the second scoring area responds first, relieving the pressure burden on the main scoring area by releasing part of the pressure. This design can effectively prevent system failure caused by premature rupture of the main scoring area and improve the overall reliability of the explosion-proof valve 5.
[0068] In addition, the existence of the second explosion-proof valve 5 also provides an additional safety backup. In extreme cases, if the main scoring area fails to rupture normally for some reason, the second explosion-proof valve 5 will serve as the last line of defense to ensure that the system will not be in danger due to excessive pressure. This dual safeguard mechanism enables the explosion-proof valve 5 to adapt to more stringent working environments and ensures the safety and stability of the industrial production process.
[0069] In summary, when the central area 1-4 is designed as a closed area and the second scoring area is arranged, the safety performance of the explosion-proof valve 5 is significantly improved. This innovative design not only increases the reliability of the explosion-proof valve 5 but also enhances its adaptability under extreme conditions, providing a more solid safety guarantee for industrial production.
[0070] According to another embodiment of the present application, an explosion-proof valve 5 is provided, including a first scoring area 2 and the above-mentioned matrix 1. The first scoring area 2 is connected to the matrix 1 along a perimeter close to the central edge of the matrix 1 for one week and along the perimeter of the matrix 1 for one week.
[0071] Specifically, this explosion-proof valve 5 ingeniously integrates two major components, namely the first scoring area 2 and the matrix 1. Particularly noteworthy is that the design of this first scoring area 2 is quite unique. It not only forms a ring structure by itself but also is closely connected to the perimeter of the matrix 1 along a perimeter close to the central edge of the matrix 1, forming an almost seamless connection.
[0072] This design strategy enables the explosion-proof valve 5, when under internal or external pressure, the first notch area 2 to serve as a "safe area" for pressure release. When the internal pressure exceeds the predetermined value, the first notch area 2 can rupture quickly and orderly, thereby releasing the pressure and avoiding dangerous situations such as explosion or rupture of the equipment. At the same time, since the first notch area 2 is tightly connected to the edge of the substrate 1, it ensures that the explosion-proof valve 5 can still maintain the structural integrity after rupture, preventing the splashing and spreading of fragments, and further improving the use safety.
[0073] In addition, the tight connection between the first notch area 2 and the edge of the substrate 1 also enhances the sealing performance of the explosion-proof valve 5. During daily use, this structure can ensure that the explosion-proof valve 5 effectively isolates the internal and external media in the closed state, avoiding leakage problems.
[0074] Generally speaking, the design of the explosion-proof valve 5 in this embodiment takes into account both the need for pressure release and the structural integrity and sealing performance, effectively improving the reliability and safety of the equipment. This design has important value in practical applications, especially in industrial environments where strict pressure control and leakage prevention are required, and will play a huge role.
[0075] In one embodiment, the first notch area 2 is in a circular ring shape, which can be a closed circular ring or a semi-closed circular ring, and the thickness of the first notch area 2 is less than the thickness of the substrate 1.
[0076] Specifically, the shape of the first notch area 2 of the explosion-proof valve 5 adopts a circular ring design, which not only has high aesthetic value but also fully considers the balance between functionality and practicality. The circular ring-shaped first notch area 2 is divided into two types: closed and semi-closed, and both designs can effectively meet the requirements of different application scenarios.
[0077] The closed circular ring notch area provides excellent structural strength and stability with its complete circular ring contour, enabling high precision and consistency during processing or treatment on it. At the same time, this design can also effectively prevent cracks or fractures in the material when subjected to external forces, ensuring the durability and reliability of the entire product.
[0078] The semi-closed circular ring notch area is more flexible and changeable. It can adjust the size and position of the opening according to actual needs to adapt to different working environments and operation requirements. This design makes the product more flexible and convenient to use and can better meet the personalized needs of users.
[0079] It is worth mentioning that the thickness of the first scored area 2 is carefully controlled to be less than the thickness of the substrate 1. This design allows the scored area to maintain sufficient strength while effectively reducing the amount of material used, thereby reducing the overall weight of the product and improving the portability and use efficiency of the product. At the same time, the thinner scored area can also reduce processing difficulty and cost, and improve production efficiency and economic benefits.
[0080] In summary, the first notched area 2 with a circular ring design not only maintains structural strength and stability, but also has multiple advantages such as flexibility, portability and efficiency. This design not only improves the overall performance and user experience of the product, but also brings convenience and benefits to the production and processing of the product.
[0081] In one embodiment, the explosion-proof valve 5 further comprises a connecting area 3 , wherein an edge of the connecting area 3 close to the center is connected to an edge of the first scoring area 2 far from the center.
[0082] Specifically, the layout and function of the connection area 3 of the explosion-proof valve 5 are crucial. The connection area 3 is located at a specific position of the explosion-proof valve 5 structure, and its key function is to connect the central area 1-4 of the explosion-proof valve 5 with the scored area. Specifically, the edge of the connection area 3 is close to the center of the explosion-proof valve 5, and the other side is closely connected to the edge of the scored area away from the center.
[0083] This layout design not only ensures the overall stability of the explosion-proof valve 5 structure, but also optimizes its response performance when pressure changes. When the internal pressure of the system where the explosion-proof valve 5 is located increases abnormally, the connection area 3 can effectively transfer the pressure to the scored area, causing the scored area to rupture quickly when the preset pressure threshold is reached, thereby releasing the excessive pressure and protecting the system safety.
[0084] The material selection and structural design of the connection area 3 are equally important. It must be able to withstand the pressure of normal system operation, and respond quickly in abnormal situations to ensure the timely rupture of the notched area. To achieve this goal, the connection area 3 is usually made of high-strength and high-toughness materials, and undergoes precise calculations and simulation tests to ensure its reliability and stability under various working conditions.
[0085] In addition, the design of the connection area 3 also takes into account the maintenance and replacement requirements of the explosion-proof valve 5. Through reasonable design, the connection area 3 can be easily separated from the other parts of the explosion-proof valve 5, which is convenient for maintenance and replacement. This not only improves the maintenance efficiency of the explosion-proof valve 5, but also reduces the maintenance cost.
[0086] In summary, the design of the connection area 3, as an important part of the explosion-proof valve 5 structure, is not only related to the performance and reliability of the explosion-proof valve 5, but also directly affects the safety and stability of the system. By carefully designing and optimizing the layout and material selection of the connection area 3, the overall performance and service life of the explosion-proof valve 5 can be significantly improved, providing a strong guarantee for the safe and stable operation of the system.
[0087] In one embodiment, the explosion-proof valve 5 further includes a welding area 4 , and an edge of the welding area 4 close to the center is connected to an edge of the connecting area 3 far from the center.
[0088] Specifically, the introduction of the welding area 4 of the explosion-proof valve 5 significantly enhances its structural strength and sealing performance. The welding area 4 is located near the central edge of the explosion-proof valve 5 and is closely connected to the edge of the connection area 3 away from the center. This layout not only ensures the overall structural stability of the explosion-proof valve 5, but also provides reliable protection for the sealing and durability of the valve.
[0089] The design of the welding area 4 takes into account that the explosion-proof valve 5 needs to withstand multiple tests such as high pressure, high temperature and corrosive environment during use. Therefore, this area usually uses high-quality welding materials and technologies to ensure that the weld is uniform and tight, and has good mechanical properties and corrosion resistance. Such a design can effectively prevent leakage or rupture caused by poor welding, and improve the safety and reliability of the explosion-proof valve 5.
[0090] In addition, the close combination of the welding area 4 and the connection area 3 further enhances the overall performance of the explosion-proof valve 5. As an important structural part of the explosion-proof valve 5, the stability of the connection area 3 is directly related to the sealing and stability of the valve under high pressure. The welding area 4 forms a complete overall structure by closely connecting the connection area 3 with the central area 1-4, thereby enhancing the overall strength and rigidity of the explosion-proof valve 5. This design enables the explosion-proof valve 5 to maintain a stable shape and size when subjected to high pressure, ensuring that the valve can work normally and effectively.
[0091] In conclusion, the welding area 4, as an important component of the explosion-proof valve 5, plays a vital role in the design of the explosion-proof valve 5. It not only enhances the structural strength and sealing performance of the explosion-proof valve 5, but also improves the stability and reliability of the valve in harsh environments such as high pressure and high temperature. This design enables the explosion-proof valve 5 to better meet the needs of various industrial applications and provides a strong guarantee for the safe and stable operation of the system.
[0092] According to another embodiment of the present application, a battery is provided, including a cover plate and the above-mentioned explosion-proof valve 5, wherein the explosion-proof valve 5 is arranged on the cover plate.
[0093] Specifically, this battery integrates a unique explosion-proof valve 5 and a carefully designed cover plate. In this design, the explosion-proof valve 5 is directly set on the cover plate, forming a complete and highly integrated safety protection system.
[0094] First of all, the design of this battery cover plate fully considers the safety and stability requirements of the battery. The precisely set explosion-proof valve 5 on the cover plate can quickly respond when the internal pressure of the battery abnormally rises, releasing the excessive pressure, thus avoiding dangerous situations such as explosion or leakage of the battery due to excessive pressure. This design greatly improves the safety performance of the battery and provides users with a more reliable usage experience.
[0095] The design of the explosion-proof valve 5 also reflects our pursuit of product performance. The explosion-proof valve 5 adopts an integral molding or composite molding process, tightly combining the central reinforcing rib 1-1, the arc-shaped cross reinforcing rib 1-2, and the straight reinforcing rib 1-3 with the matrix 1 to form a solid framework structure. This design not only improves the strength and stability of the explosion-proof valve 5 but also ensures its reliability in extreme environments such as high pressure and high temperature.
[0096] When the internal pressure of the battery rises, the scored area of the explosion-proof valve 5 will first deform and rupture, thus quickly releasing the excessive pressure. Especially when the central area 1-4 is designed as a closed area and a second scored area is set, the central area 1-4 and the second scored area thereon together form a second explosion-proof valve 5, providing double safety guarantees for the battery. This double guarantee mechanism can ensure that the battery can still operate stably under extreme conditions, bringing users a safer and more reliable energy support.
[0097] In addition, the tight combination of the cover plate and the explosion-proof valve 5 also enhances the overall sealing performance of the battery. This design can prevent external impurities from entering the battery interior and keep the internal environment of the battery clean and stable. At the same time, the materials and processes of the cover plate and the explosion-proof valve 5 have been carefully selected and optimized to ensure that they can maintain long-term stability and reliability in various working environments.
[0098] In summary, the design of this battery integrated with the explosion-proof valve 5 and the cover plate not only improves the safety performance and stability of the battery but also brings users a more reliable and safe energy solution. We believe that this innovative design will be more widely applied and promoted in the future.
