Description

Technical Field

[0001] The present invention relates to the technical field of battery protective cases, and specifically to a channel-type battery protective shell. Background Art

[0002] At present, with the booming development of new energy technologies, batteries, as the core energy storage components, are widely used in the fields of electric vehicles, energy storage power stations, and portable electronic devices. However, during the actual use of batteries, the electrolyte is susceptible to leakage due to various factors such as temperature, humidity, vibration, and shock. This not only leads to a decline in battery performance but may even trigger accidents such as fires and explosions. To ensure battery safety, using a protective shell to protect the battery has become a common practice in the industry.

[0003] Currently, most of the battery protective cases on the market achieve the protective function through a high-strength shell. With a closed structure design, although it can resist external impacts and the intrusion of moisture to a certain extent, there are many drawbacks. From the perspective of heat dissipation, the closed protective shell hinders the heat exchange between the battery and the outside world. When the battery generates a large amount of heat under high-load working conditions, the internal heat is difficult to effectively dissipate, resulting in a continuous increase in the battery temperature, entering a vicious cycle, accelerating battery aging and reducing the service life. At the same time, high temperatures can also trigger battery thermal runaway, posing serious safety hazards. In response to humidity, although the existing sealed protective cases can block the entry of external moisture, in an environment with alternating cold and heat, the temperature difference between the inside and outside of the shell is likely to cause condensation water vapor inside. Once these water vapors adhere to the battery electrodes or other key components, it will cause problems such as battery short circuits and corrosion, seriously threatening the stability and safety of the battery. In the face of vibration and shock, the existing protective cases only rely on the strength of the shell itself and lack a targeted anti-seismic and buffer structure design, unable to effectively absorb and disperse vibration and impact forces. When the battery encounters vehicle bumps or transportation collisions, the key components such as internal electrodes and diaphragms are prone to displacement and damage, thereby damaging the battery structure and increasing the risk of electrolyte leakage. In addition, during the battery storage process, due to the fixed structure of the existing protective cases, it is difficult to achieve flexible stacking or combination, resulting in low utilization rate of the unit storage space, increasing the enterprise's warehousing costs and management difficulties. And once electrolyte leakage occurs, the existing protective cases lack an effective electrolyte collection and treatment mechanism, and the leaked electrolyte will spread inside the shell, further corroding the battery and the protective case, expanding the scope of damage. Therefore, there is an urgent need to develop a new type of battery protective case that can effectively solve heat dissipation, moisture prevention, earthquake resistance, space utilization, and electrolyte treatment.

[0004] Therefore, the present invention proposes a channel-type battery protective shell to solve the above problems. Summary of the Invention

[0005] In view of this, the technical problem to be solved by the present invention is to provide a channel-type battery protection housing to solve the problems existing in the prior art.

[0006] To achieve the above object, the present invention provides the following technical solution: A channel-type battery protection housing, including: a partition plate, and further including: a first component and a second component, the second component being located inside the first component; The first component is used to maintain the stability and seismic performance of the batteries on the left and right sides of the partition plate and undertake the water cooling work; The second component is used to prevent the humidity from eroding the battery, handle the risk of electrolyte leakage, and undertake the air cooling work.

[0007] As an improvement, the first component includes a bottom plate arranged below the partition plate. Column cavity grooves are equidistantly opened on the bottom plate. Rubber support columns are inserted into the column cavity grooves. Partition slots are equidistantly opened on the bottom plate. The partition plate is inserted and fixed in the partition slots.

[0008] As an improvement, stability grooves are equidistantly opened on the bottom plate. Support foot columns are inserted into the stability grooves. A closing plate is slidably connected to the two support foot columns. An insertion threaded rod is inserted through the closing plate. The upper end of the support foot column supports a cover plate. The insertion threaded rod passes through the cover plate. A bolt is threadedly connected to the upper end of the insertion threaded rod.

[0009] As an improvement, a wavy groove is opened on the inner wall of the closing plate. A water cooling pipe is arranged in the wavy groove. Triangular blocks are fixedly connected to the water cooling pipe.

[0010] As an improvement, the second component includes a through opening A opened through the closing plate. A threaded connecting member is threadedly connected in the through opening A. An air pipe is fixedly connected to the threaded connecting member.

[0011] As an improvement, a first longitudinal groove plate and a second longitudinal groove plate are fixedly connected in the closing plate. A through opening B is opened through the first longitudinal groove plate. A through opening C is opened through the second longitudinal groove plate.

[0012] As an improvement, a through opening D is opened on the inner wall of the closing plate.

[0013] As an improvement, a wire threading auxiliary pipe is arranged on one side of the water cooling pipe. The wire threading auxiliary pipe is located inside the closing plate.

[0014] As an improvement, both the support foot columns and the closing plate are provided with four. A sealing gasket is arranged at the bottom end of the cover plate.

[0015] As an improvement, the longitudinal opening heights of the through-ports A, B, and D are as follows. The through-ports A and D are at the same height. The through-port B is higher than the through-ports A and D, and the through-ports B and C are at the same height longitudinally.

[0016] Compared with the prior art, the present invention provides a channel-type battery protection housing, which has the following beneficial effects: 1. The cooperation between the bottom plate and the support foot columns in the first component of the present invention can bring the following benefits: Precise and stable support to ensure reliable operation of the battery: The position grooves provided on the bottom plate highly match the outer contour of the battery, enabling precise positioning of the battery and restricting the displacement of the battery in the horizontal direction; The support foot columns are vertically installed on the bottom plate and cooperate with the position grooves to form a stable three-dimensional support structure; During the operation of the battery, the above stable support method can also effectively reduce the shaking of the battery, avoid damage to internal components such as electrodes and diaphragms due to displacement, thereby reducing the risk of electrolyte leakage and ensuring the safe and reliable operation of the battery; Flexibly adapt to different specifications of batteries and improve versatility: The support foot columns and the bottom plate are detachably connected. By changing the installation position and combination number of the support foot columns in the position grooves on the bottom plate, that is, the stable grooves, the size and layout of the support structure can be quickly adjusted to adapt to batteries of different sizes and shapes; Whether it is a battery for a small portable electronic device or a large power battery for an electric vehicle, it can be installed and fixed on the stable system formed by the cooperation of the bottom plate and the support foot columns, without the need to separately design a dedicated protection structure for different specifications of batteries, greatly improving the versatility and scope of use, and reducing the R & D and production costs of enterprises; Convenient for storage and saving space resources: In the non-use state, the support foot columns can be easily detached from the bottom plate. The detached support foot columns can be stacked for storage, and the bottom plate can also be stacked for storage. Compared with the traditional integrated battery protection structure, this detachable design significantly reduces the space occupied during storage. For enterprises or places that need to store a large number of battery protection components, it can greatly improve the utilization rate of warehouse space, save warehouse costs, and at the same time facilitate space management during transportation and improve transportation efficiency.

[0017] 2. The cooperation between the water-cooling pipe and the triangular block in the present invention can bring the following benefits: Combining multiple effects to enhance the fixing stability of the battery: The triangular blocks on the water-cooling pipe contact the battery surface with their shapes, forming multiple support force points, which can exert constraints on the battery from different directions and effectively restrict the displacement of the battery within the protection housing composed of the support foot columns and the closed plate; Compared with the traditional single fixing method, the contact area between the triangular blocks and the battery is larger and evenly distributed, and the battery can be firmly fixed within the protection housing; Auxiliary buffering to resist impact and protect the battery: The water body filled inside the water cooling pipe has good fluidity and compressibility. When the battery is subjected to a large impact or shaking, the water body can quickly absorb the impact energy and disperse the impact force through its own flow and deformation. When an external impact force acts on the battery, the water cooling pipe, as a buffering medium, can effectively reduce the direct action of the impact force on the battery, convert the impact force into the kinetic energy and internal energy of the water body, greatly improve the impact resistance of the battery, and extend the service life of the battery; Function multiplexing to improve space utilization efficiency: The water cooling pipe integrates three functions: temperature control, battery fixation, and impact buffering, making full use of the limited space resources inside the protective shell. There is no need to additionally install independent structural components for battery fixation and impact buffering, reducing the number of components and layout space inside the protective shell. The above design not only makes the battery protection structure more compact, but also reduces the overall weight and volume of the protective shell, improves space utilization efficiency, helps to achieve the miniaturization and lightweight design of the battery protective shell, and meets the strict requirements for equipment space and weight in different application scenarios; Cooperate to ensure the stable operation of the battery: The temperature control, fixation, and buffering functions of the water cooling pipe do not operate independently, but cooperate with each other. During the operation of the battery, the water cooling pipe continuously controls the temperature to maintain a suitable operating temperature for the battery. At the same time, the triangular block always keeps the battery firmly fixed, preventing the battery from shifting due to thermal expansion and contraction caused by temperature changes. When encountering impact or shaking, the internal water body quickly plays a buffering role, protecting the battery while ensuring the stability of the fixation structure of the water cooling pipe and avoiding fixation failure caused by impact. The above multi-functional cooperation mode creates a stable and safe operating environment for the battery, significantly improving the comprehensive performance and reliability of the battery; Reduce costs and facilitate maintenance and replacement: Since the water cooling pipe integrates multiple functions, reducing the use of multiple independent components, it reduces the material cost and processing cost during the production and manufacturing process. At the same time, the modular design makes the installation, disassembly, and maintenance of the water cooling pipe more convenient. When the water cooling pipe fails or is damaged, it can be directly replaced as a whole without having to repair and adjust other complex fixation or buffering structures, greatly reducing the maintenance difficulty and maintenance cost. In addition, the reduced number of components also reduces the failure rate of the system.

[0018] 3. The design of the first longitudinal slot plate and the second longitudinal channel plate in the present invention can bring the following benefits: Strengthen the structural support and improve the overall stability of the protective shell: The bending shapes of the first longitudinal groove plate and the second longitudinal groove channel plate form a natural reinforcing rib effect in the mechanical structure; the geometric shape at the bending part can effectively disperse the pressure from the closed plate and external impact forces, evenly conduct the stress to all parts of the protective shell. Compared with the straight structure, the groove plate with a bending shape can increase the compressive strength of the closed plate. When it is subjected to heavy object extrusion or severe collision, it can effectively prevent the closed plate from deforming and cracking, build a more solid protective barrier for the battery, and greatly improve the overall structural stability and durability of the protective shell.

[0019] 4. Based on the cooperation of the first longitudinal groove plate and the second longitudinal groove channel plate in the second component and the closed plate in the first component, with the assistance of the through-hole, the following benefits can be brought: Non-contact heat dissipation and enhance the battery protection performance: The non-direct contact air-cooling cooling method realized by the air duct and the through-hole provides a physical isolation barrier for the battery; in complex usage environments, such as dusty, humid or corrosive gas environments, external pollutants cannot directly contact the battery surface, reducing the risk of battery short-circuit and corrosion failures caused by external factors; at the same time, the water-cooling pipe adopts a sealed design and keeps a safe distance from the battery to avoid damage to the battery caused by coolant leakage, further enhancing the battery protection performance and improving the safety and stability of the battery operation. Efficient dual temperature control to ensure the stable working temperature of the battery: Through the air duct structure formed by the cooperation of the first longitudinal groove plate, the second longitudinal groove channel plate and the closed plate, the air circulation can be effectively realized by using the through-holes opened on it. Without direct contact between the battery and the outside world, the heat generated during the battery operation can be effectively taken away, avoiding damage caused by direct contact of dust, water vapor and impurities with the battery; on this basis, the addition of the auxiliary water-cooling pipe builds a dual temperature control system. With the high specific heat capacity characteristic of water, the water-cooling system can quickly absorb a large amount of heat and cooperate with the air-cooling to greatly improve the heat dissipation efficiency. Optimize the heat dissipation structure and improve the space utilization efficiency: The combination of the first longitudinal groove plate, the second longitudinal groove channel plate and the closed plate cleverly uses the internal space of the battery protective shell to build an air duct without occupying too much extra space; the water-cooling pipe can be flexibly arranged according to the wave grooves on the inner wall of the closed plate, effectively fitting the battery and arranging along the edge of the closed plate. While achieving efficient heat dissipation, it does not affect the installation space of the battery and other components; the above compact heat dissipation structure design makes the most of the internal space of the protective shell on the premise of ensuring the heat dissipation function, which is conducive to the miniaturization and lightweight design of the battery protective shell, meeting the requirements of different application scenarios for the volume and weight of the battery. Reduce energy consumption and achieve energy conservation and environmental protection: The dual temperature control system can be intelligently adjusted according to the actual working temperature of the battery; when the battery temperature is low, only the air cooling system is started, and natural convection or a low-power air pump is used to achieve heat dissipation, reducing energy consumption; when the battery temperature rises to a certain threshold, the water cooling system is started, and the two work together. Through the above control method, the energy waste caused by the long-term high-power operation of the traditional heat dissipation system is avoided, the overall energy consumption is reduced. At the same time, the efficient heat dissipation design reduces the performance loss of the battery caused by overheating, extends the service life of the battery, indirectly reduces the battery replacement frequency, and conforms to the concept of energy conservation and environmental protection.

[0020] 5. The height difference of the openings of the through-port A, through-port B, through-port C, and through-port D in the present invention can bring the following benefits: Efficient water vapor barrier to ensure the safe operation of the battery: The difference in the longitudinal opening height of the through-ports constructs a unique air flow path; when the external humid air enters the air duct and flows through the through-ports at different heights, due to the change in the air flow direction and speed, the water vapor in the air will settle due to inertia and gravity, and the water vapor will gradually separate due to gravity and cannot directly contact the battery surface; this design can reduce the relative humidity of the air entering the closed plate, effectively avoiding problems such as battery short circuit and electrode corrosion caused by water vapor, creating a dry and safe working environment for the battery, and improving the reliability and service life of the battery; Delay the leakage of electrolyte and reduce the pollution risk: When the battery leaks electrolyte, the through-ports at different heights form multiple physical barriers; the leaked electrolyte needs to overcome the obstacles of gravity and the height difference of the through-ports to flow out of the closed plate or the protective shell. The above design significantly extends the time for the electrolyte to leak to the outside of the protective shell, winning valuable time for timely discovery and handling of the leakage problem. At the same time, the flow path of the electrolyte in the protective shell becomes tortuous due to the height change of the through-ports, further slowing down the leakage speed, effectively reducing the risk of the electrolyte polluting and damaging external electrical equipment, and ensuring the normal operation of the surrounding equipment.

At the same time, the detachable manner of the support foot columns 206 on the bottom plate 201 has the characteristics of storage on the basis of battery adaptability, saving storage space, and only requiring the replacement of local components in case of individual damage, with a low scrap rate.

[0030] There are four support foot columns 206 and the closing plate 207 respectively. The closing plate 207 is restricted and fixed by two adjacent support foot columns 206.

[0031] A sealing gasket is provided at the bottom end of the cover plate 209, which is used to block external moisture and sundries from entering the battery protection sealing shell composed of itself, the bottom plate 201, and the closing plate 207.

[0032] Snap pieces are provided on the wave groove 211 for the stable placement of the water-cooling pipe 212.

[0033] The rubber support column 203 and the triangular block 213 cooperate, and with the assistance of the partition plate 1, they have the function of stabilizing the batteries.

[0034] For a further embodiment: Please refer to Figure 2 、 Figure 3 、 Figures 6 to 12 as shown: The second component 3 is used to prevent the battery from being eroded by humidity, handle the risk of electrolyte leakage, and undertake the work of air-cooled cooling. The second component 3 includes a through port A301 formed through the closing plate 207. A threaded connecting member 302 is threadedly connected within the through port A301. An air pipe 303 is fixedly connected to the threaded connecting member 302. A first longitudinal groove plate 304 and a second longitudinal channel plate 306 are fixedly connected within the closing plate 207. A through port B305 is formed through the first longitudinal groove plate 304. A through port C307 is formed through the second longitudinal channel plate 306. A through port D308 is formed on the inner wall of the closing plate 207. A wire threading auxiliary pipe 309 is arranged on one side of the water-cooling pipe 212, and the wire threading auxiliary pipe 309 is located within the closing plate 207.

[0035] Among them: The second component 3 is used to prevent the battery from being eroded by humidity, handle the risk of electrolyte leakage, and undertake the work of air-cooled cooling.

[0036] The longitudinal opening heights of the through port A301, the through port B305, and the through port D308 are as follows. The through port A301 and the through port D308 are at the same height, and the through port B305 is higher than the through port A301 and the through port D308.

[0037] During use, an air pump can be externally connected to the threaded connecting member 302 through the air pipe 303 for air-cooled temperature control, or it can be used alone.

[0038] The first longitudinal groove plate 304 and the inner wall of the closing plate 207 form a first cavity. A second cavity is formed between the first longitudinal groove plate 304 and the second longitudinal channel plate 306. A third cavity is formed between the second longitudinal channel plate 306 and the other inner wall of the closing plate 207. Further, during the air-cooling process of the through port A301, the moisture carried by the air body will first enter the first cavity. Only after entering the first cavity and being filled up will it enter the second cavity through the through port B305, and only after being filled up again can it enter the third cavity to affect the battery. Reference can be made to the appendix Figure 11 ; When the battery electrolyte leaks, on the contrary, the electrolyte will first enter the third cavity through the through port D308, and so on, and then it can flow out of the protective shell composed of the closing plate 207. Reference can be made to the appendix Figure 12 .

[0039] The through port B305 and the through port C307 are at the same height longitudinally.

[0040] The wire threading auxiliary pipe 309 is used for threading the battery connection lines, and this pipe is in close contact with the water-cooling pipe 212. While the water-cooling cools the battery, it can also take into account the temperature of the lines.

[0041] The working principle of all the contents in the above embodiments is as follows: The following is the working process of the first component 2: When in use, the device body must first be assembled; specifically, the operator selects a suitable bottom plate 201 according to the size of the battery, and then places the rubber support column 203 in the column cavity groove 202 to support the bottom end of the battery, and at the same time inserts the partition plate 1 into the partition slot 204 to separate the batteries in the battery pack. Furthermore, according to the position where the battery is placed, the support leg 206 is plugged into the stabilizing groove 205 opened on the bottom plate 201. After the plugging is completed, the four symmetrically distributed support legs 206 will be located at the four corners of the battery position. Then, further, the water cooling pipe 212 is fastened to the wave groove 2 through the snap-fit piece. 11, and then slide the closing plate 207 with the water cooling pipe 212 into the supporting foot column 206 to splice the side wall of the protective shell. Furthermore, insert the plug-in threaded rod 208 into the supporting foot column 206 and match it with the threaded thread in the stabilizing groove 205. After rotating the plug-in threaded rod 208 to vertically fix the plug-in threaded rod 208 on the bottom plate 201, the cover plate 209 with the sealing gasket is buckled on the top of the supporting foot column 206, and then the cover plate 209 penetrating the plug-in threaded rod 208 is fixed with the bolt 210. At this point, the protective shell assembly consisting of the bottom plate 201, the supporting foot column 206, and the cover plate 209 is completed. Furthermore, when in use, the water cooling tube 212 will cool down the battery under the action of the water flowing therein, and the triangular block 213 thereon can be used to assist in fixing the battery; Furthermore, the water cooling tube 212 and the triangular block 213 are used in combination to achieve multiple effects in one, and the function of strengthening the stability of battery fixation is achieved; that is, the triangular block 213 on the water cooling tube 212 contacts the battery surface with its shape, forming multiple supporting points, which can constrain the battery from different directions, and effectively limit the displacement of the battery in the protective shell formed by the supporting legs 206 and the closing plate 207; compared with the traditional single fixing method, the contact area between the triangular block 213 and the battery is larger and evenly distributed, so that the battery can be firmly fixed in the protective shell; Auxiliary buffering, resisting impact and protecting the battery: the water filled in the water cooling tube 212 has good fluidity and compressibility. When the battery is subjected to a large impact or shaking, the water can quickly absorb the impact energy and disperse the impact force through its own flow and deformation. When the external impact force acts on the battery, the water cooling tube 212 acts as a buffer medium, which can effectively reduce the direct effect of the impact force on the battery and convert the impact force into the kinetic energy and internal energy of the water, greatly improving the impact resistance of the battery and extending the battery life. Function reuse to improve space utilization efficiency: The water-cooling pipe 212 integrates three functions: temperature control, battery fixation, and shock buffering. It makes full use of the limited space resources inside the protective shell, eliminating the need for additional independent structural components for battery fixation and shock buffering. This reduces the number of components and layout space inside the protective shell. The above design not only makes the battery protection structure more compact but also reduces the overall weight and volume of the protective shell, improving space utilization efficiency and contributing to the miniaturization and lightweight design of the battery protective shell to meet the strict requirements for device space and weight in different application scenarios; Cooperate to ensure stable battery operation: The temperature control, fixation, and buffering functions of the water-cooling pipe 212 do not operate independently but cooperate with each other. During battery operation, the water-cooling pipe 212 continuously controls the temperature to maintain an appropriate working temperature for the battery. At the same time, the triangular block 213 always keeps the battery firmly fixed, preventing the battery from shifting due to thermal expansion and contraction caused by temperature changes. When encountering impacts or vibrations, the internal water body quickly plays a buffering role, protecting the battery and ensuring the stability of the fixation structure of the water-cooling pipe 212, avoiding fixation failure caused by impacts. The above multi-functional cooperation mode creates a stable and safe working environment for the battery, significantly improving the comprehensive performance and reliability of the battery; Reduce costs and facilitate maintenance and replacement: Since the water-cooling pipe 212 integrates multiple functions, reducing the use of multiple independent components, it reduces the material cost and processing cost during the manufacturing process. At the same time, the modular design makes the installation, disassembly, and maintenance of the water-cooling pipe 212 more convenient. When the water-cooling pipe 212 fails or is damaged, it can be directly replaced as a whole without repairing and adjusting other complex fixation or buffering structures, greatly reducing the maintenance difficulty and cost. In addition, the reduced number of components also reduces the system failure rate.

[0042] Please refer to the above working process Figures 1 to 5 、 Figure 10 。

[0043] The following is the working process of the second component 3: Furthermore, as known, the first longitudinal groove plate 304 and the inner wall of the closing plate 207 form a first cavity, the first longitudinal groove plate 304 and the second longitudinal channel plate 306 form a second cavity, and the second longitudinal channel plate 306 and the other inner wall of the closing plate 207 form a third cavity. Further, during the air-cooling process through the port A301, the moisture carried by the air body will first enter the first cavity. Only after entering and filling the first cavity will it enter the second cavity through the port B305 and then enter the third cavity to affect the battery only after filling the second cavity again. Please refer to the appendix Figure 11; When the battery electrolyte leaks, on the contrary, the electrolyte will first enter the third cavity through the through-port D308, and so on, before it can flow out of the protective shell composed of the closing plate 207. Please refer to the appendix Figure 12 ; Furthermore, based on the cooperation of the first longitudinal groove plate 304, the second longitudinal channel plate 306 in the second component 3 and the closing plate 207 in the first component 2, with the assistance of the through-ports, non-contact heat dissipation can be effectively achieved, enhancing the battery protection performance; that is, the non-direct contact air-cooling method realized by the air ducts and through-ports provides a physical isolation barrier for the battery; in complex usage environments, such as dusty, humid or corrosive gas environments, external pollutants cannot directly contact the battery surface, reducing the risk of battery short-circuit and corrosion failures caused by external factors; at the same time, the water-cooling pipe 212 adopts a sealed design, maintaining a safe distance from the battery to avoid damage to the battery caused by coolant leakage, further enhancing the battery protection performance and improving the safety and stability of battery operation; Efficient dual temperature control to ensure stable battery operating temperature: Through the air duct structure formed by the cooperation of the first longitudinal groove plate 304, the second longitudinal channel plate 306 and the closing plate 207, the air circulation can be effectively achieved through the through-ports opened thereon. Without direct contact between the battery and the outside, the heat generated during battery operation can be effectively removed, avoiding damage caused by direct contact of dust, water vapor and impurities with the battery; On this basis, the addition of the auxiliary water-cooling pipe 212 constructs a dual temperature control system. With the high specific heat capacity characteristic of water, the water-cooling system can quickly absorb a large amount of heat and cooperate with the air-cooling to greatly improve the heat dissipation efficiency; Optimize the heat dissipation structure and improve the space utilization efficiency: The combination of the first longitudinal groove plate 304, the second longitudinal channel plate 306 and the closing plate 207 cleverly utilizes the internal space of the battery protective shell to construct air ducts without occupying too much additional space; The water-cooling pipe 212 can be flexibly arranged according to the wave grooves 211 on the inner wall of the closing plate 207, effectively fitting the battery and arranging along the edge of the closing plate 207. While achieving efficient heat dissipation, it does not affect the installation space of the battery and other components; The above compact heat dissipation structure design maximizes the utilization of the internal space of the protective shell on the premise of ensuring the heat dissipation function, which is conducive to the miniaturization and lightweight design of the battery protective shell, meeting the requirements of different application scenarios for the battery volume and weight; Furthermore, the height differences formed by the through-ports A301, B305, C307, and D308 can bring about efficient water and gas barrier, ensuring the safe operation of the battery; that is, the differences in the longitudinal opening heights of the through-ports create a unique air flow path. When external humid air enters the air duct and flows through the through-ports at different heights, due to the change in the air flow direction and speed, the water vapor in the air will settle due to inertia and gravity, and the water vapor will gradually separate due to gravity and cannot directly contact the battery surface. This design can reduce the relative humidity of the air entering the closed plate 207, effectively avoiding battery short circuits and electrode corrosion problems caused by water vapor, creating a dry and safe working environment for the battery, and enhancing the reliability and service life of the battery. Delay electrolyte leakage and reduce pollution risk: When the battery leaks electrolyte, the through-ports at different heights form multiple physical barriers. The leaked electrolyte needs to overcome the obstacles of gravity and the height difference of the through-ports to flow out of the closed plate 207 or the protective shell. The above design significantly extends the time for the electrolyte to leak to the outside of the protective shell, buying precious time for timely detection and handling of leakage problems. At the same time, the flow path of the electrolyte in the protective shell becomes tortuous due to the height change of the through-ports, further slowing down the leakage speed and effectively reducing the risk of the electrolyte polluting and damaging external electrical equipment, ensuring the normal operation of surrounding equipment.
