Description

Technical Field

[0001] This application relates to the field of energy storage cabinet technology, and in particular to a sealing adapter and its assembly method, and a computer program product. Background Technology

[0002] As the core equipment of an electrochemical energy storage system, the heat dissipation performance of the internal battery compartment of the energy storage cabinet directly affects the battery's operating efficiency, lifespan, and system safety. The air duct structure, a key component of the energy storage cabinet's heat dissipation system, is used to introduce cool air into the battery compartment and cool the battery pack. Its connection method, sealing performance, and adaptability have a significant impact on the overall cabinet's assembly efficiency, protection level, and operation and maintenance costs.

[0003] Currently, the connection between the air duct and the battery compartment of the energy storage cabinet is mainly achieved by fixed welding or bolt fastening. The air duct is mostly made of two interlocking air duct plates fully welded at the joint. Due to the lightweight requirements of the battery cabinet, the thickness of the air duct plate is limited, and problems such as weld burn-through are very easy to occur during the welding process, resulting in poor air tightness. During the operation of the air duct, hot and cold airflows are prone to crossflow at the joint, leading to a significant decrease in heat dissipation efficiency. Summary of the Invention

[0004] The main purpose of this application is to provide a sealing adapter and its assembly method, as well as a computer program product, which aims to solve the technical problem of poor airtightness between the air duct and the battery compartment.

[0005] To achieve the above objectives, this application proposes a sealing adapter device for use in an energy storage cabinet, the sealing adapter device comprising: A modular layered branch air duct, one end of which is provided with an annular stepped docking surface, and the other end of which is used to connect with the main air duct of the energy storage cabinet. The battery compartment air inlet is located on the side of the battery compartment of the energy storage cabinet. The battery compartment air inlet has a stepped interface that matches the stepped docking surface, and the inner side of the stepped interface of the battery compartment air inlet is provided with an annular groove. A sealing component is embedded in the annular groove, and the sealing component has an arc-shaped protrusion on the side facing the stepped mating surface; when the stepped mating surface of the modular layered branch air duct is plugged into the stepped interface, the end face of the stepped mating surface axially presses against the arc-shaped protrusion to form an airtight seal.

[0006] In one embodiment, the sealing adapter further includes: The quick-connect assembly includes a quick-connect buckle and a buckle connector. The buckle connector is disposed on the outer periphery of the air inlet of the battery compartment. One end of the quick-connect buckle is hinged to the outer periphery of the modular layered branch air duct, and the other end is a buckle end. The buckle end is snapped and fixed to the buckle connector, and the quick-connect buckle has a self-locking function after being snapped.

[0007] In one embodiment, the snap-fit ​​connector is integrally formed with the battery compartment air inlet, and the surface of the quick-connect snap-fit ​​is provided with anti-slip texture.

[0008] In one embodiment, the sealing assembly includes a fluororubber sealing ring, which is embedded in the annular groove and has an interference fit with the annular groove.

[0009] In one embodiment, the length of the modular layered branch air duct is replaced according to the specifications of the battery pack in the battery compartment to accommodate battery compartments of different sizes.

[0010] To achieve the above objectives, this application proposes an assembly method for a sealing adapter, the assembly method comprising: The sealing assembly is embedded in the annular groove of the battery compartment air inlet so that the sealing assembly fits into the annular groove; The stepped mating surface of the modular layered branch air duct is aligned with the air inlet of the battery compartment, and the modular layered branch air duct is pushed to make the stepped mating surface fit against the arc-shaped protrusion of the sealing assembly.

[0011] In one embodiment, after the steps of aligning the stepped docking surface of the modular layered branch air duct with the air inlet of the battery compartment and controlling the pushing of the modular layered branch air duct, the method further includes: Compressed air is supplied to the assembled modular layered branch air duct, and the air pressure inside the modular layered branch air duct is maintained at a preset air pressure value. Detect the air leakage at the junction of the stepped docking surface and the air inlet of the battery compartment; When the air leakage is less than a preset threshold, the sealing adapter is deemed to be in good condition.

[0012] In one embodiment, after the steps of aligning the stepped docking surface of the modular layered branch air duct with the air inlet of the battery compartment and controlling the pushing of the modular layered branch air duct, the method further includes: Control the quick-connect buckle to engage with the buckle connector, and control the quick-connect buckle to be pressed into a self-locking state so that the modular layered branch air duct is engaged and fixed with the battery compartment air inlet.

[0013] In one embodiment, the method further includes: When it is necessary to replace the battery pack with one of different specifications, the self-locking state of the quick-connect buckle is released, and the modular layered branch air duct is disassembled from the air inlet of the battery compartment. Determine the length of another modular layered branch air duct to match the specifications of the replaced battery pack, and return to the step of embedding the control sealing assembly into the annular slot of the battery compartment air inlet interface and subsequent steps.

[0014] In addition, to achieve the above objectives, this application also provides a computer program product, which includes a computer program that, when executed by a processor, implements the steps of the assembly method for the sealing adapter as described above.

[0015] One or more technical solutions proposed in this application have at least the following technical effects: By using the stepped docking surface of the modular, layered branch air duct to form a plug-in fit with the stepped interface of the battery compartment air inlet, rapid and precise docking between the air duct and the battery compartment is achieved, improving assembly efficiency and positioning reliability. At the same time, with the help of the sealing component and its arc-shaped protrusion structure embedded in the annular slot, the end face of the stepped docking surface is axially pressed against the arc-shaped protrusion during the plug-in process, thereby forming a stable airtight seal, preventing cooling air leakage, ensuring the uniformity and efficiency of ventilation and heat dissipation inside the battery compartment, and improving the overall heat dissipation performance, sealing reliability and operational safety of the energy storage cabinet.

[0019] The purpose, features, and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0020] It should be understood that the specific embodiments described herein are merely illustrative of the technical solutions of this application and are not intended to limit this application.

[0021] To better understand the technical solution of this application, a detailed description will be provided below in conjunction with the accompanying drawings and specific implementation methods.

[0022] The main solution of this application embodiment is to propose a sealing adapter device, including: a modular layered branch air duct, one end of which is provided with a stepped mating surface, and the other end of which is used to connect with the main air duct of the energy storage cabinet; a battery compartment air inlet, which is located on the side of the battery compartment of the energy storage cabinet, and has a stepped interface that matches the stepped mating surface, and the inner side of the stepped interface of the battery compartment air inlet is provided with an annular groove; a sealing component, which is embedded in the annular groove, and the side of the sealing component facing the stepped mating surface is provided with an arc-shaped protrusion; when the stepped mating surface of the modular layered branch air duct is inserted and matched with the stepped interface, the end face of the stepped mating surface axially presses the arc-shaped protrusion to form an airtight seal.

[0023] In this embodiment, for ease of description, the following description will focus on the assembly equipment of the sealing adapter as the main body.

[0024] This application provides a solution that achieves rapid and precise docking between the air duct and the battery compartment by using a stepped mating surface of the modular layered branch air duct to form a plug-in fit with the stepped interface of the battery compartment air inlet. This improves assembly efficiency and positioning reliability. At the same time, by using the sealing component and its arc-shaped protrusion structure embedded in the annular groove, the end face of the stepped mating surface is axially pressed against the arc-shaped protrusion during the plug-in process, thereby forming a stable airtight seal. This prevents cooling airflow leakage, ensures the uniformity and efficiency of ventilation and heat dissipation inside the battery compartment, improves the overall heat dissipation performance, sealing reliability, and operational safety of the energy storage cabinet, and thus guarantees the heat dissipation performance of the energy storage cabinet.

[0025] This application provides a sealing adapter device, referring to... Figure 1This device, applied to energy storage cabinets, includes a sealing adapter comprising: a modular layered branch air duct 100, one end of which has an annular stepped mating surface 101, and the other end of which is used to connect with the main air duct of the energy storage cabinet; a battery compartment air inlet 400, located on the side of the battery compartment of the energy storage cabinet, having a stepped interface that matches the stepped mating surface 101, and an annular groove 401 on the inner side of the stepped interface; and a sealing component 300, which is embedded in the annular groove 401, with an arc-shaped protrusion 301 on the side of the sealing component 300 facing the stepped mating surface 101; when the stepped mating surface 101 of the modular layered branch air duct 100 is inserted into the stepped interface, the end face of the stepped mating surface 101 axially presses against the arc-shaped protrusion 301 to form an airtight seal.

[0026] The sealing adapter can be applied to multi-layer battery compartment scenarios, with each layer of battery compartment equipped with an independent sealing adapter structure.

[0027] In this embodiment, the modular layered branch air duct 100 is used to guide the airflow from the main air duct to the battery compartment. The stepped interface of the battery compartment air inlet 400 matches the stepped mating surface 101 of the modular layered branch air duct 100. When they are mated, they form a stepped fit, which can effectively increase the length and complexity of the airflow leakage path and improve the fit and sealing effect of the mating surface. For example, the step height of the stepped mating surface 101 is 5mm and the step width is 10mm. Optionally, the modular layered branch air duct 100 can be made of metal and the surface can be treated with anti-corrosion to extend its service life. For example, the modular layered branch air duct 100 is made of aluminum alloy and the surface is anodized.

[0028] The modular layered branch air duct 100 and the battery compartment air inlet interface 400 adopt an axial push-in docking, which eliminates the need for bolt fastening or welding operations. The assembly and disassembly process is simple and quick, which greatly shortens the assembly time and improves maintenance efficiency.

[0029] The modular layered branch air duct 100 can be flexibly replaced with modular layered branch air ducts 100 of different lengths according to the specifications of the battery pack, without the need to reconstruct the overall air duct. It is compatible with various battery pack specifications and has good versatility and scalability.

[0030] It should be noted that the annular groove 401 is used to install the sealing assembly 300, ensuring that the sealing assembly 300 is accurately positioned and securely installed. For example, the annular groove 401 has a width of 10mm and a depth of 5mm.

[0031] Optionally, the sealing component 300 is an annular elastic sealing ring. After being embedded in the annular groove 401, the sealing component 300 forms an interference fit with the groove, ensuring that the sealing component 300 is stably positioned within the groove and does not shift. The arc-shaped protrusion 301 serves as the core sealing structure of the sealing component 300. When the stepped mating surface 101 of the modular layered branch air duct 100 mates with the air inlet 400 of the battery compartment, the arc-shaped protrusion 301 is compressed and undergoes elastic deformation, tightly fitting with the stepped mating surface 101 to form a reliable sealing interface.

[0032] The sealing component 300 is made of fluororubber, which has excellent high and low temperature resistance and aging resistance. It can maintain stable elastic sealing performance in a wide temperature range of -40℃ to 200℃. The overall structure has a long service life, reducing the frequency of maintenance and replacement.

[0033] The stepped mating surface 101 and the stepped interface are designed to work together, and the arc-shaped protrusion 301 of the sealing component 300 provides elastic deformation sealing, forming a multi-layered sealing barrier. The stepped structure effectively extends the leakage path of airflow, and the arc-shaped protrusion 301 undergoes elastic deformation under pressure to fill the tiny gaps in the mating surface. The two work together to achieve a high level of sealing, such as IP65, effectively preventing the crossflow of hot and cold airflow and ensuring heat dissipation efficiency. The overall structure has few parts, and the sealing component 300 is reliably positioned within the annular groove 401. There are no complex transmission or linkage mechanisms, making manufacturing easier, cost-effective, and ensuring good long-term stability.

[0034] During assembly, the sealing component 300 is first embedded into the annular groove 401 of the battery compartment air inlet 400, ensuring a tight fit and no misalignment between the sealing component 300 and the groove. Then, the stepped mating surface 101 of the modular layered branch air duct 100 is aligned with the stepped interface of the battery compartment air inlet 400, and the modular layered branch air duct 100 is pushed axially, causing the stepped mating surface 101 to contact and press against the arc-shaped protrusion 301 of the sealing component 300. As the mating proceeds, the arc-shaped protrusion 301 undergoes elastic deformation, filling the tiny gap between the stepped mating surface 101 and the stepped interface, achieving a surface seal. The stepped mating structure of the stepped mating surface 101 and the stepped interface further extends the potential leakage path of the airflow, working synergistically with the elastic seal of the arc-shaped protrusion 301 to achieve a high level of sealing.

[0035] When it is necessary to disassemble or replace the modular layered branch air duct 100, simply pull it out axially; the operation is simple and quick. To accommodate different battery pack specifications, the corresponding length of the modular layered branch air duct 100 can be replaced without reconstructing the entire air duct system.

[0036] As an optional implementation, the sealing component 300 is a fluororubber sealing ring with a Shore hardness of 70±5. Fluororubber has excellent high and low temperature resistance, can withstand temperatures from -40℃ to 200℃, and has aging resistance, which can meet the environmental requirements for long-term outdoor operation of the energy storage cabinet.

[0037] As an optional implementation, the width of the annular groove 401 is 8mm to 15mm and the depth is 3mm to 8mm, which matches the size of the sealing assembly 300 to ensure that the sealing assembly 300 is firmly positioned after being installed.

[0038] As an optional implementation, the height of the arc-shaped protrusion 301 is 2mm to 5mm. The arc-shaped surface of the arc-shaped protrusion 301 is conducive to uniform deformation under pressure, forming a larger contact area with the stepped mating surface 101, thereby improving the sealing reliability.

[0039] As an optional implementation, the stepped mating surface 101 of the modular layered branch air duct 100 has a step height of 3mm to 8mm and a step width of 8mm to 15mm. This size range can ensure good sealing effect while taking into account the convenience of processing and manufacturing.

[0040] In the technical solution of this embodiment, the stepped docking surface 101 of the modular layered branch air duct 100 and the stepped interface of the battery compartment air inlet 400 form a plug-in fit, realizing the rapid and accurate docking between the air duct and the battery compartment, improving assembly efficiency and positioning reliability; at the same time, with the help of the sealing component 300 and its arc-shaped protrusion 301 structure embedded in the annular slot 401, the end face of the stepped docking surface 101 is axially pressed against the arc-shaped protrusion 301 during the plug-in process, thereby forming a stable airtight seal, preventing cooling air leakage, ensuring the uniformity and efficiency of ventilation and heat dissipation inside the battery compartment, and improving the overall heat dissipation performance, sealing reliability and operational safety of the energy storage cabinet.

[0041] In an optional embodiment, the sealing adapter further includes a quick-connect assembly, which includes a quick-connect buckle 200 and a buckle connector 402. The buckle connector 402 is disposed on the outer periphery of the battery compartment air inlet 400. One end of the quick-connect buckle 200 is hinged to the outer periphery of the modular layered branch air duct 100, and the other end is a buckle end. The buckle end is snapped and fixed to the buckle connector 402, and the quick-connect buckle 200 has a self-locking function after being snapped.

[0042] Optionally, the quick-connect buckle 200 is made of elastic stainless steel with a thickness of 1.5mm to 3mm. Made of elastic stainless steel, the quick-connect buckle 200 possesses excellent elasticity, corrosion resistance, and fatigue resistance, maintaining stable elasticity and locking force during long-term repeated locking and unlocking operations. The quick-connect buckle 200 has an overall arc or U-shaped structure, its shape matching the outer periphery of the modular layered branch air duct 100. One end of the quick-connect buckle 200 has a hinge hole, which is hinged to a hinge seat fixedly set on the outer periphery of the modular layered branch air duct 100 via a hinge pin, allowing the quick-connect buckle 200 to rotate around the hinge pin within a predetermined angle range. The other end of the quick-connect buckle 200 is a latching end, which has a hook or barb structure for engaging with the latching connector 402.

[0043] The snap-fit ​​connector 402 is made of the same material as the battery compartment air inlet 400, such as steel or stainless steel, and is integrally formed with the battery compartment air inlet 400 to ensure connection strength. The hinge pin can be made of stainless steel, and the hinge connector is welded to or integrally formed with the outer periphery of the modular layered branch air duct 100.

[0044] To facilitate manual operation, the outer surface of the quick-connect buckle 200 can be provided with anti-slip texture. Operators can press or pull the quick-connect buckle 200 by hand to complete the locking and unlocking operations without the need for additional tools.

[0045] Optionally, the snap-fit ​​connector 402 is disposed on the outer periphery of the battery compartment air inlet 400. The snap-fit ​​connector 402 is integrally formed with the battery compartment air inlet 400 or fixedly connected, such as by welding or bolting. The position of the snap-fit ​​connector 402 corresponds to the snap-fit ​​end of the quick-connect snap 200. When the modular layered branch air duct 100 is aligned with the battery compartment air inlet 400, the snap-fit ​​end is located directly above or to the outside of the snap-fit ​​connector 402. The snap-fit ​​connector 402 is provided with a locking protrusion or locking groove that engages with the hook or barb of the quick-connect snap 200.

[0046] Optionally, the quick-connect buckle 200 has an elastic hook at its buckle end. The free end of the elastic hook has a guide slope and a locking surface. The guide slope guides the buckle during insertion, and the locking surface locks it in place to prevent it from coming off. The buckle connecting seat 402 has a locking boss that matches the elastic hook. When the operator presses the quick-connect buckle 200 to rotate it around the hinge pin axis towards the buckle connecting seat 402, the guide slope of the elastic hook first contacts the locking boss. Under the pressure, the elastic hook elastically deforms and opens outward, passing the locking boss and then elastically returning to its original position. At this time, the locking surface of the elastic hook abuts against the corresponding surface of the locking boss, forming a self-locking mechanism to prevent the quick-connect buckle 200 from accidentally coming off under external force. Optionally, the self-locking function has clear tactile and / or auditory feedback. When the quick-connect buckle 200 is engaged in the self-locking position, the operator can sense the engagement through touch and / or hearing, ensuring controllable assembly quality.

[0047] After completing the installation of the sealing assembly 300, align the stepped mating surface 101 of the modular layered branch air duct 100 with the stepped interface of the battery compartment air inlet 400, and push the modular layered branch air duct 100 axially to initially align them. At this time, the quick-connect buckle 200 is in the open state, i.e., not engaged with the buckle connector 402. The operator holds the outer surface of the quick-connect buckle 200 and presses it towards the battery compartment air inlet 400. The quick-connect buckle 200 rotates around the hinge pin, and the elastic hook at the buckle end gradually approaches the locking boss of the buckle connector 402. Continue pressing, and the elastic hook elastically resets after passing the locking boss, forming a self-locking mechanism. At this time, the modular layered branch air duct 100 and the battery compartment air inlet 400 are tightened and fixed by the quick-connect buckle 200, and the stepped mating surface 101 further squeezes the arc-shaped protrusion 301 of the sealing component 300. The arc-shaped protrusion 301 is further compressed, generating greater elastic deformation and achieving enhanced sealing.

[0048] In the self-locking state, the locking surface of the elastic hook abuts against the corresponding surface of the locking boss. Even if vibration occurs during the operation of the energy storage cabinet, the quick-connect buckle 200 will not accidentally loosen, ensuring a long-term stable and reliable sealing state. When it is necessary to disassemble the modular layered branch air duct 100, the operator pinches the buckle end of the quick-connect buckle 200, applies external force to cause the elastic hook to elastically deform and disengage from the locking boss, thus releasing the self-locking. Then, the quick-connect buckle 200 is moved away from the buckle connecting seat 402 to switch it to the open state. Finally, the modular layered branch air duct 100 can be pulled out axially.

[0049] Optionally, multiple quick-connect components are provided, arranged circumferentially at intervals along the modular layered branch air duct 100 and the battery compartment air inlet 400. For example, the number of quick-connect components is 2 to 6, evenly distributed circumferentially. When multiple quick-connect components are simultaneously tightened, the modular layered branch air duct 100 is subjected to a uniform axial compressive force, ensuring that the arc-shaped protrusion 301 of the sealing component 300 is uniformly compressed circumferentially, avoiding local seal failure due to uneven compressive force.

[0050] As an alternative implementation, the quick-connect buckle 200 can also be a ring-shaped clamp structure. One end of the ring-shaped clamp has a hinged connection, and the other end has a buckle end. It is locked by clamping the connection between the modular layered branch air duct 100 and the battery compartment air inlet 400. The quick-connect buckle 200 of the ring-shaped clamp structure also has a self-locking function, and its self-locking method is similar to that described above, so it will not be repeated.

[0051] In this embodiment, the quick-connect assembly and the sealing assembly 300 work together to achieve a high level of sealing. After the quick-connect buckle 200 is locked, the stepped mating surface 101 of the modular layered branch air duct 100 continuously compresses the arc-shaped protrusion 301 of the sealing assembly 300 under the axial tension force provided by the quick-connect buckle 200. Compared with the traditional bolt tightening method, the locking force of the quick-connect buckle 200 can be preset by the elastic deformation of the quick-connect buckle 200 and the position of the buckle connecting seat 402, ensuring good consistency of the clamping force after each tightening, avoiding the problem of uneven clamping force caused by differences in manual operation during bolt tightening, thereby ensuring the stability and repeatability of the sealing quality.

[0052] As an alternative implementation, the sealing adapter may not require a quick-connect assembly. In this simplified structure, the modular layered branch air duct 100 and the battery compartment air inlet 400 are sealed only by the elastic fit between the arc-shaped protrusion 301 of the sealing assembly 300 and the stepped mating surface 101. The modular layered branch air duct 100 maintains its mating position by its own weight or by external fixing structures (such as brackets, clamps, etc.). This structure is suitable for scenarios with relatively low sealing requirements or limited assembly space, and has the advantages of simpler structure and lower cost.

[0053] In this embodiment, by hinged quick-connect buckles 200 to the outer periphery of the modular layered branch air duct 100 and snapped into place with snap-connecting seats 402 on the outer periphery of the battery compartment air inlet 400, a quick tool-free connection between the modular layered branch air duct 100 and the battery compartment air inlet 400 is achieved, improving assembly efficiency and ease of operation. The hinged design also prevents parts from scattering or being lost. Furthermore, the quick-connect buckles 200 have a self-locking function after snapping, effectively resisting vibrations and external interference during the operation of the energy storage cabinet, preventing the connection from loosening. This ensures the long-term stability and reliability of the connection between the modular layered branch air duct 100 and the battery compartment air inlet 400, thereby guaranteeing the continuous and effective airtight sealing performance of the sealing assembly 300 and improving the structural stability and operational safety of the entire sealing adapter device.

[0054] In an optional embodiment, the snap-fit ​​connector 402 and the battery compartment air inlet 400 are integrally formed, and the surface of the quick-connect snap 200 is provided with anti-slip texture. Specifically, the snap-fit ​​connector 402 and the battery compartment air inlet 400 are made of the same metal material, such as steel or stainless steel, and are integrally formed by casting, forging, or machining. The snap-fit ​​connector 402 protrudes outward from the outer peripheral wall of the battery compartment air inlet 400, and its protrusion direction is consistent with the radial direction of the battery compartment air inlet 400. The protruding structure of the snap-fit ​​connector 402 is provided with a locking boss or locking groove for engaging with the snap-fit ​​end of the quick-connect snap 200.

[0055] The one-piece molding structure eliminates weld seams or fastener interfaces between the snap-fit ​​connector 402 and the battery compartment air inlet 400, removing the risk of welding heat-affected zones or bolt loosening. The overall structure boasts high strength, capable of withstanding alternating loads generated by repeated snap-fit ​​and unlocking operations of the quick-connect snap 200, ensuring high reliability over long-term use. The one-piece molding process ensures the relative positional accuracy between the snap-fit ​​connector 402 and the battery compartment air inlet 400, particularly the axial positional accuracy of the locking boss on the snap-fit ​​connector 402 relative to the end face of the battery compartment air inlet 400. This axial positional accuracy directly affects the amount of pressure exerted by the quick-connect snap 200 on the sealing component 300 after locking; higher positional accuracy results in better consistency of sealing pressure and more stable sealing quality. The absence of connection gaps between the snap-fit ​​connector 402 and the battery compartment air inlet 400 eliminates any path for airflow leakage, contributing to improved overall sealing performance. The elimination of subsequent assembly processes such as welding or bolting reduces manufacturing difficulty and cost, and improves production efficiency.

[0056] As an alternative implementation, the snap-fit ​​connector 402 and the battery compartment air inlet 400 can be separate structures, fixedly connected by welding, riveting, or bolting. This structure is suitable for scenarios where the snap-fit ​​connector 402 needs to be made of different materials or have different heat treatment processes than the battery compartment air inlet 400, offering greater manufacturing flexibility.

[0057] The quick-connect buckle 200 has an anti-slip texture on its surface. This anti-slip texture is located on the outer surface of the quick-connect buckle 200, i.e., the surface that the operator contacts when pressing it, such as in the middle and / or near the buckle end. Specific forms of the anti-slip texture include, but are not limited to, knurling, raised dot texture, wavy texture, or serrated texture, or one or more combinations thereof. Knurling involves creating a cross-hatched or straight-lined texture on the surface of the quick-connect buckle 200 using a knurling process, with a knurling depth of 0.2mm to 0.6mm. Knurling effectively increases the friction between the fingers and the surface of the quick-connect buckle 200, preventing slippage during operation. Raised dot texture involves an array of hemispherical or frustum-shaped raised dots on the surface of the quick-connect buckle 200, with a dot height of 0.3mm to 0.8mm and a spacing of 1.5mm to 3mm between adjacent dots. Raised dot texture also increases friction and provides good tactile feedback. The wavy or serrated texture consists of wavy or serrated protrusions along the width of the quick-connect clip 200. The protrusions extend perpendicularly to the length of the quick-connect clip 200, with a height of 0.3mm to 0.7mm and a spacing of 1mm to 2.5mm between adjacent protrusions. This texture provides maximum friction when the operator applies pressure along the length, and it matches well with the operating direction of the quick-connect clip 200.

[0058] In this embodiment, the integrated design of the snap-fit ​​connector 402 and the battery compartment air inlet 400, combined with the anti-slip texture on the surface of the quick-connect snap 200, ensures connection strength and sealing accuracy while improving the operability and reliability of manual operation, achieving a fast, accurate, and reliable assembly effect. The anti-slip texture ensures that fingers can apply firm force when operating with one hand in a limited space, allowing for pressing and locking of the quick-connect snap 200 and unlocking without tools, significantly improving assembly and disassembly efficiency. The anti-slip texture reduces the risk of slippage due to hand sweat, oil, or smooth glove surfaces, ensuring reliable operation each time and preventing issues such as the quick-connect snap 200 not being fully locked or unlocked due to improper operation. The anti-slip texture enhances the operator's tactile feedback; combined with the tactile and / or audible feedback when the quick-connect snap 200 locks itself, the operator can clearly perceive whether the operation is in place, ensuring assembly quality.

[0059] In an optional embodiment, the sealing assembly 300 includes a fluororubber sealing ring, which is inserted into the annular groove 401 and is press-fitted with the annular groove 401.

[0060] The sealing component 300 includes a fluororubber sealing ring, meaning the main material of the sealing component 300 is fluororubber. Fluororubber is a synthetic polymer elastomer containing fluorine atoms on its main or side chain carbon atoms. Fluororubber can operate stably for extended periods within a wide temperature range of -40℃ to 200℃, with short-term operating temperatures reaching up to 230℃. Energy storage cabinets are deployed in outdoor environments where winter temperatures in frigid regions can drop below -40℃, and summer temperatures and equipment operating temperatures can cause the internal temperature of the air duct to exceed 80℃. The fluororubber sealing ring maintains good elasticity and sealing performance under these extreme temperature conditions, without hardening, cracking, or softening deformation, ensuring reliable sealing in both high and low temperature environments. Fluororubber also possesses excellent resistance to ozone, ultraviolet radiation, and atmospheric aging. Its performance degradation is minimal under long-term outdoor exposure, and its service life is far superior to ordinary rubbers such as natural rubber, nitrile rubber, and neoprene rubber. Fluororubber exhibits excellent resistance to various chemical media, such as acids, alkalis, oils, and solvents. The corrosive environments that energy storage cabinets may encounter, such as salt spray and acidic gases, will not cause significant corrosion or performance degradation to the fluororubber sealing rings. Fluororubber maintains good elastic recovery under long-term compression, with a low compression set. The sealing assembly 300 remains under compression after being locked by the quick-connect clip 200; this low compression set ensures that the sealing assembly 300 maintains sufficient clamping force and sealing effect even after long-term use.

[0061] In this embodiment, the Shore hardness of the fluororubber sealing ring is preferably 70±5. If the hardness is too low, such as below 60 degrees, the sealing ring is prone to excessive deformation or even being squeezed out of the sealing gap under pressure; if the hardness is too high, such as above 80 degrees, the elastic deformation ability of the sealing ring decreases, making it difficult to fill the tiny gaps between the mating surfaces, and the sealing effect is reduced. In this application, the fluororubber sealing ring with a Shore hardness of 70±5 achieves a good balance between elasticity and extrusion resistance.

[0062] After the fluororubber sealing ring is embedded in the annular groove 401, it is interference-fitted with the annular groove 401. The radial thickness of the fluororubber sealing ring is greater than the radial depth of the annular groove 401. When the fluororubber sealing ring is embedded in the annular groove 401, the outer circumferential surface of the fluororubber sealing ring is tightly fitted with the bottom wall of the annular groove 401, and the inner circumferential surface of the fluororubber sealing ring (i.e., the side facing the axis) is higher than the inner wall surface of the battery compartment air inlet 400, forming an interference fit, i.e., an interference fit. Optionally, the radial thickness of the fluororubber sealing ring is 0.5mm to 1.5mm greater than the radial depth of the annular groove 401. This interference fit ensures that the fluororubber sealing ring is firmly clamped in the annular groove 401 and will not shift, rotate, or fall off during assembly or use, while also preventing the fluororubber sealing ring from being difficult to install or undergoing irreversible compression deformation due to excessive interference fit. The axial width of the fluororubber sealing ring is basically the same as the axial width of the annular groove 401. Optionally, the axial width of the fluororubber sealing ring is 0.2mm to 0.5mm smaller than the axial width of the annular groove 401 to facilitate the installation and embedding of the fluororubber sealing ring, while avoiding axial movement within the groove.

[0063] The fluororubber sealing ring is tightly held within the annular groove 401 via an interference fit, achieving reliable positioning without the need for additional adhesives or fasteners. Even during continuous vibrations in the energy storage cabinet, the sealing ring will not deviate from its predetermined installation position, ensuring that the arc-shaped protrusion 301 of the sealing ring is always accurately aligned with the stepped mating surface 101 of the modular layered branch air duct 100. The fluororubber sealing ring has a certain degree of elastic deformation capability, allowing it to be pressed into the annular groove 401 by hand or with simple tools. The clamping force of the interference fit is automatically formed after installation, eliminating the need to wait for adhesive curing or perform other auxiliary fixing operations, resulting in high assembly efficiency. The interference fit also ensures a tight contact between the outer circumferential surface of the fluororubber sealing ring and the wall surface of the annular groove 401. This contact interface itself constitutes a sealing barrier, forming a double sealing effect together with the seal at the arc-shaped protrusion 301, further enhancing the overall sealing level.

[0064] In this embodiment, the fluororubber sealing ring has an annular structure, and its cross-sectional shape is preferably asymmetrical. The side of the fluororubber sealing ring facing away from the stepped mating surface 101 (i.e., the side embedded in the bottom of the annular groove 401) is a flat surface or an arc-shaped surface matching the bottom wall of the annular groove 401, to ensure good fit with the bottom wall of the annular groove 401. An arc-shaped protrusion 301 is provided on the side of the fluororubber sealing ring facing the stepped mating surface 101. The cross-section of the arc-shaped protrusion 301 is circular, with a radius of 2mm to 4mm, and the height of the arc-shaped protrusion 301 (i.e., the distance between the apex of the arc-shaped protrusion 301 and the end face of the sealing ring base) is 2mm to 5mm.

[0065] The cross-section of the sealing ring substrate can be designed as rectangular or trapezoidal. When it is a trapezoidal cross-section, the short base of the trapezoid faces the stepped mating surface 101, and the long base faces the bottom of the annular groove 401. This design is beneficial for the sealing ring substrate to be squeezed towards the side wall of the annular groove 401 under pressure, further enhancing the sealing effect between the sealing ring and the side wall of the groove.

[0066] In the technical solution of this embodiment, the sealing component 300 adopts a fluororubber sealing ring and forms an interference fit with the annular groove 401. On the one hand, the excellent high temperature resistance, chemical corrosion resistance and aging resistance of fluororubber ensure the stability and durability of the sealing ring under long-term operation and complex working conditions of the energy storage cabinet, and extend the service life of the seal. On the other hand, the interference fit enables the sealing ring to obtain reliable radial preload and positioning constraint in the groove, preventing the sealing ring from shifting, falling off or twisting during insertion or vibration. This ensures continuous and stable axial compression sealing between the arc-shaped protrusion 301 and the end face of the stepped mating surface 101, and improves the reliability and long-term effectiveness of the overall airtight seal.

[0067] In an optional embodiment, the length of the modular layered branch air duct 100 is replaced according to the specifications of the battery pack in the battery compartment to adapt to battery compartments of different sizes. Specifically, the modular layered branch air duct 100 is an independent modular component, and it is detachably connected to the main air duct of the energy storage cabinet and to the air inlet interface 400 of the battery compartment, such as by plug-in, snap-fit, or flange connection. The main structure of the modular layered branch air duct 100 is a straight cylindrical or slightly curved tubular structure, and its cross-sectional shape is preferably circular. Optionally, the outer diameter is 100mm to 200mm, and it can also be square or elliptical, depending on the overall design of the air duct system.

[0068] One end of the modular layered branch air duct 100, i.e., the docking end, is provided with a stepped docking surface 101. The size and shape of the stepped docking surface 101 are fixed to ensure that it always matches the stepped interface of the battery compartment air inlet interface 400. The other end of the modular layered branch air duct 100, i.e., the end that connects to the main air duct, is provided with a connection structure such as a flange, plug joint, or clamp interface for connecting with the corresponding interface of the main air duct.

[0069] The length of the modular layered branch air duct 100 can be selected according to the specifications of the battery pack in the battery compartment. Different manufacturers or models of battery packs have differences in dimensions such as height and width, which causes the position of the battery compartment air inlet 400 relative to the main air duct to change accordingly. By selecting modular layered branch air ducts 100 of different lengths, the stepped docking surface 101 can be precisely aligned with the battery compartment air inlet 400, achieving reliable docking.

[0070] Before installing or replacing the battery pack, determine the required length of the modular layered branch air duct 100 based on the dimensions and specifications of the selected battery pack. A table comparing battery pack specifications with the length of the modular layered branch air duct 100 can be pre-established for quick selection. If the existing modular layered branch air duct 100 is already installed in the energy storage cabinet, first disconnect the modular layered branch air duct 100 from the battery compartment air inlet 400, such as by releasing the self-locking of the quick-connect clip 200, pulling out the modular layered branch air duct 100, and then disconnecting the second end of the modular layered branch air duct 100 from the main air duct, thus disassembling the old modular layered branch air duct 100. Select a new modular layered branch air duct 100 of the corresponding length, first connect and fix the second end of the new modular layered branch air duct 100 to the main air duct, then align and connect the stepped mating surface 101 of the first end of the new modular layered branch air duct 100 with the stepped interface of the battery compartment air inlet 400, and finally lock and secure it using the quick-connect clip 200 to complete the assembly.

[0071] In the sealing adapter of this application, the stepped mating surface 101 of the modular layered branch air duct 100 has a standardized interface size. Modular layered branch air ducts 100 of different lengths only differ in length, and the size and shape of the stepped mating surface 101 at their first ends are exactly the same. Therefore, multiple battery compartment air inlets 400 in the same energy storage cabinet can share the same type of stepped interface. It is only necessary to select the corresponding length of modular layered branch air duct 100 according to the specifications of the battery PACK in each battery compartment.

[0072] The modular, layered, branched air duct 100 can be made of aluminum alloy with an anodized surface. Aluminum alloy is lightweight, with a density of approximately 2.7 g / cm³, far lower than steel's 7.8 g / cm³, which is beneficial for the lightweight design of the energy storage cabinet. It also boasts excellent heat dissipation performance due to its high thermal conductivity, which facilitates heat dissipation within the duct itself. Furthermore, it exhibits good corrosion resistance, as the anodizing process forms a dense aluminum oxide protective film, significantly enhancing its corrosion resistance and enabling it to withstand outdoor use. Finally, it offers good machinability, as aluminum alloy is easy to extrude and machine, making it suitable for mass production.

[0073] As another optional implementation, the modular layered branch duct 100 can also be made of stainless steel or engineering plastics. Stainless steel has higher strength and is suitable for scenarios with higher structural strength requirements; engineering plastics are low-cost and have good insulation properties, making them suitable for low-pressure or weight-sensitive scenarios.

[0074] In the technical solution of this embodiment, the modular layered branch air duct 100 adopts a length replaceable design, which can be flexibly adjusted and adapted according to the specifications of different battery packs and the size of the battery compartment. This allows the same sealing adapter to be compatible with energy storage cabinets of various models and sizes, improving the versatility and modularity of the product. This not only reduces the cost and time of redesigning or manufacturing the entire air duct system due to differences in battery compartment size, but also facilitates standardized production, warehousing management and flexible on-site configuration.

[0075] Based on this, the present application provides an assembly method for a sealing adapter, referring to... Figure 2 , Figure 2 This is a flowchart illustrating the first embodiment of the assembly method for the sealing adapter of this application.

[0076] In this embodiment, the assembly method of the sealing adapter includes steps S10~S20: Step S10: Control the sealing component to be embedded in the annular slot of the battery compartment air inlet, so that the sealing component fits into the annular slot.

[0077] In this embodiment, the sealing assembly 300 is controlled and aligned with the annular groove 401 on the end face of the battery compartment air inlet 400. Since the outer diameter of the sealing assembly 300 is slightly larger than the bottom diameter of the annular groove 401, i.e., the two are interference fit, a uniform force needs to be applied along the circumference of the sealing assembly 300 to gradually press the sealing assembly 300 into the annular groove 401. During the pressing process, a non-metallic tool such as a nylon rod or rubber mallet can be used to tap the end face of the sealing assembly 300 to ensure even embedding.

[0078] After the sealing assembly 300 meets the preset installation conditions, the sealing assembly 300 is confirmed to be installed in place. Meeting the preset installation conditions includes at least one of the following: the side of the sealing assembly 300 facing the stepped mating surface 101 is higher than the end face of the battery compartment air inlet 400 by a preset height, such as 1mm to 3mm, to ensure that the arc-shaped protrusion 301 can be fully compressed during subsequent mating; the sealing assembly 300 is tightly fitted to each wall surface of the annular groove 401 without obvious gaps or looseness; the sealing assembly 300 is circumferentially uniform within the annular groove 401, without twisting or flanging, and the arc-shaped protrusion 301 is correctly oriented, i.e., towards the outside of the battery compartment air inlet 400, which is also towards the direction of the modular layered branch air duct 100.

[0079] If the sealing assembly 300 is misaligned, twisted, or not in place after installation, it should be removed and reinstalled promptly. A flathead screwdriver or a special removal tool can be used to pry it out from the edge of the sealing assembly 300, taking care to avoid damaging the surface of the sealing assembly 300 or the annular groove 401.

[0080] Step S20: Align the stepped mating surface of the modular layered branch air duct with the air inlet of the battery compartment, and push the modular layered branch air duct so that the stepped mating surface fits against the arc-shaped protrusion of the sealing component.

[0081] In this embodiment, the modular layered branch air duct 100 is controlled and clamped, aligning the stepped docking surface 101 with the stepped interface of the battery compartment air inlet 400. During alignment, it is important to ensure that the circumferential angles of each step surface of the stepped docking surface 101 match the corresponding step surface of the stepped interface. Specifically, if the step is a ring-shaped step, there is no circumferential angle requirement; if the step is a non-ring-shaped step, alignment must be performed at a preset angle.

[0082] After alignment, the control system slowly pushes the modular layered branch air duct 100 along its axial direction, i.e., toward the battery compartment air inlet 400. During this pushing process, the stepped mating surface 101 gradually approaches the arc-shaped protrusion 301 of the sealing assembly 300. Once they contact each other, the control system continues to apply an appropriate axial thrust, causing the arc-shaped protrusion 301 to be compressed and elastically deformed. The arc-shaped surface of the arc-shaped protrusion 301 then fits tightly against the stepped mating surface 101, forming a preliminary seal.

[0083] During the pushing process, preset control conditions need to be met, including at least one of the following: the pushing speed should be uniform and slow to avoid impact that could damage or misalign the sealing component 300; the applied axial thrust should be along the axial direction of the modular layered branch air duct 100 to avoid skew that could cause the stepped mating surface 101 to jam or scrape against the stepped interface; when the detected resistance increases, i.e. the arc-shaped protrusion 301 begins to be compressed, the pushing speed is controlled to slow down, and the arc-shaped protrusion 301 is gradually deformed to the predetermined compression amount by relying on continuous pressure.

[0084] When the axial displacement of the modular layered branch air duct 100 reaches the predetermined value, that is, when the distance between the stepped docking surface 101 and the end face of the battery compartment air inlet 400 reaches the design value, the pushing stops. At this time, the stepped docking surface 101 and the arc protrusion 301 of the sealing component 300 are in a tight fit, and the initial seal is formed.

[0085] Optionally, before step S10, a layer of lubricant, such as silicone grease or special sealing grease, can be evenly applied to the surface of the arc-shaped protrusion 301 or the stepped mating surface 101 to reduce frictional resistance during mating and prevent the sealing component 300 from twisting or being damaged during extrusion. The lubricant itself can also fill minor surface defects, further improving the sealing effect. The amount of lubricant applied should be moderate, ideally without dripping or running.

[0086] As another optional implementation, the air duct docking step can be completed by an automatic alignment device, such as setting guide rails and positioning fixtures in the energy storage cabinet. The modular layered branch air duct 100 moves directionally along the guide rails to ensure precise alignment and docking with the battery compartment air inlet interface 400, which is suitable for mass assembly or installation scenarios of large energy storage systems.

[0087] In the technical solution of this embodiment, the stepped docking surface 101 of the modular layered branch air duct 100 and the stepped interface of the battery compartment air inlet 400 form a plug-in fit, realizing the rapid and accurate docking between the air duct and the battery compartment, improving assembly efficiency and positioning reliability; at the same time, with the help of the sealing component 300 and its arc-shaped protrusion 301 structure embedded in the annular slot 401, the end face of the stepped docking surface 101 is axially pressed against the arc-shaped protrusion 301 during the plug-in process, thereby forming a stable airtight seal, preventing cooling air leakage, ensuring the uniformity and efficiency of ventilation and heat dissipation inside the battery compartment, and improving the overall heat dissipation performance, sealing reliability and operational safety of the energy storage cabinet.

[0088] Based on the first embodiment of this application, in the second embodiment of this application, the same or similar content as the above embodiment can be referred to the above description, and will not be repeated hereafter. Based on this, please refer to... Figure 3 After step S20, the following steps are also included: Step S30: Control the supply of compressed air into the assembled modular layered branch air duct and maintain the air pressure in the modular layered branch air duct at a preset air pressure value. Step S40: Detect the air leakage at the junction of the stepped docking surface and the air inlet of the battery compartment; Step S50: When the air leakage is less than a preset threshold, the sealing adapter is deemed to be qualified.

[0089] In this embodiment, the sealing performance of the sealing adapter is tested using either the differential pressure method or the pressure decay method. Specifically, compressed air at a certain pressure is introduced into the modular layered branch duct 100, making the internal pressure of the duct higher than the external ambient pressure, thus creating a positive pressure difference. By detecting the air leakage at the connection point, the sealing performance can be quantitatively evaluated. Under this pressure difference, if there is a leak at the connection point of the sealing adapter, the internal compressed air will escape outward through the leakage path.

[0090] Optionally, a compressed air source is connected to the end where the modular layered branch air duct 100 communicates with the main air duct, and an air compressor or an air storage tank can be selected as the air source. A pressure regulating valve and a pressure gauge or a pressure sensor are arranged on the pipeline between the air source and the modular layered branch air duct 100, and the intake pressure is adjusted by the pressure regulating valve, so that the air pressure in the modular layered branch air duct 100 is stabilized at a preset pressure value. Optionally, the preset pressure value is 400 Pa to 600 Pa, and illustratively, the preset pressure value is 500 Pa. The 500 Pa is slightly higher than the air pressure range of the energy storage cabinet air duct during normal operation, which is usually 200 Pa to 400 Pa, so that the reliability of the sealing structure can be verified with a certain safety margin, and at the same time, the pressure will not be too high to cause the sealing assembly 300 to generate abnormal large deformation or be extruded out of the sealing gap.

[0091] After the air pressure is established, the pressure needs to be kept stable for a preset duration, such as 1 min to 3 min, so that the stress relaxation of the sealing assembly 300 tends to be stable, and inaccurate detection results caused by initial stress fluctuation are avoided.

[0092] The air leakage can be detected by a flowmeter method: a gas flowmeter is installed in series on the pipeline between the air source and the modular layered branch air duct 100, and the value of the flowmeter is read after the air pressure is stabilized. Under an ideal sealing state, the gas flow rate should tend to zero. The reading of the flowmeter is the air leakage at the butt joint. The air leakage can also be detected by a pressure decay method. Firstly, the inside of the modular layered branch air duct 100 is pressurized to a preset air pressure value, then the air source valve is closed to make the modular layered branch air duct 100 become a closed system, and the change of the pressure in the closed system over time is monitored by a pressure sensor. The air leakage is calculated according to the pressure decay rate in combination with the volume of the air duct system. The air leakage can also be detected by a bubble method or a soap solution method. Soap solution is applied to the outer periphery of the butt joint between the stepped butt surface 101 and the air inlet interface 400 of the battery compartment, or the butt joint is immersed in water, to observe whether there are continuous bubbles escaping. If continuous bubbles exist, it indicates that there is a leakage. This method is easy to operate and is suitable for rapid qualitative judgment.

[0093] When the air leakage is less than a preset threshold, the sealing adaptation device is judged to be qualified in sealing. The preset threshold is determined according to the sealing grade requirement of the energy storage cabinet. In this embodiment, when the air leakage at the butt joint is ≤0.01 m³ / h, the sealing is judged to be qualified. The air leakage threshold of 0.01 m³ / h corresponds to the requirement of the IP65 sealing grade. Under this air leakage, external dust cannot invade the interior of the air duct, and moisture cannot penetrate under the condition of low water pressure spraying, which can meet the protection requirements for outdoor use of the energy storage cabinet.

[0094] If the detected air leakage is greater than 0.01 m³ / h, the seal is deemed unqualified and further inspection is required. At this point, check the following possible causes: whether the sealing component 300 is installed correctly and whether it is twisted, misaligned, or damaged; whether the stepped mating surface 101 of the modular layered branch duct 100 has scratches, deformation, or foreign matter adhering to it; whether the quick-connect buckle 200 is fully locked and whether the locking force is sufficient; whether there are foreign objects or processing burrs in the annular groove 401, causing the sealing component 300 to not fully fit against the bottom wall of the groove. After troubleshooting and taking appropriate action, repeat the inspection steps of this embodiment until the inspection is qualified.

[0095] For each sealing adapter of each energy storage cabinet, the test results are recorded to form an assembly quality traceability file. Optionally, the inspection results include information such as test air pressure, air leakage, test date, and operator. When the energy storage cabinet experiences abnormal heat dissipation or sealing-related failures during operation, the traceability file can be used to quickly locate the problematic batch and cause, facilitating quality analysis and improvement.

[0096] In the technical solution of this embodiment, by introducing compressed air and maintaining a preset air pressure value after the modular layered branch air duct 100 is assembled, and then quantitatively detecting the air leakage at the docking point, the online rapid verification and quantitative evaluation of the sealing performance of the sealing adapter device is realized. This can timely and accurately detect assembly defects such as improper installation of the sealing component 300, excessive fitting clearance, or sealing failure, preventing unqualified products from entering subsequent processes or being put into operation. At the same time, using the preset air pressure value and air leakage threshold as objective judgment standards eliminates the subjectivity and uncertainty of manual experience judgment, improves the accuracy, consistency, and traceability of sealing detection, thereby ensuring the airtight sealing quality of the energy storage cabinet battery compartment and ensuring the reliable operation and overall safety of its ventilation and heat dissipation system.

[0097] Based on any embodiment of this application, in the third embodiment of this application, the content that is the same as or similar to the above embodiments can be referred to the above description, and will not be repeated hereafter. Based on this, please refer to... Figure 4 After step S20, the following steps are also included: Step S60: Control the quick-connect buckle to engage with the buckle connector seat, and control the quick-connect buckle to be pressed into a self-locking state so that the modular layered branch air duct is engaged and fixed with the battery compartment air inlet.

[0098] In this embodiment, after the air duct is connected and the stepped connection surface 101 is initially attached to the arc protrusion 301 of the sealing component 300, the quick-connect buckle 200 is pressed towards the battery compartment air inlet 400 with the hinge pin as the rotation center in the middle or near the buckle end area.

[0099] Under pressure, the quick-connect buckle 200 rotates around the hinge pin, and the elastic hook at the buckle end gradually approaches the locking boss of the buckle connector 402. The guide slope of the elastic hook contacts the locking boss. With continued pressing, the elastic hook undergoes elastic deformation under the interaction of the guide slope and the locking boss, passing over the locking boss. After the elastic hook passes the highest point of the locking boss, it recovers its elasticity, and the locking surface of the elastic hook abuts against the corresponding surface of the locking boss, forming a self-locking mechanism. In the self-locking state, the quick-connect buckle 200 remains locked by the engagement of the elastic hook and the locking boss, without the need for continuous external force.

[0100] After the quick-connect clip 200 is locked, the modular layered branch air duct 100 is pulled towards the battery compartment air inlet 400 by the quick-connect clip 200. Since the stepped mating surface 101 and the arc-shaped protrusion 301 of the sealing component 300 have already made contact during the initial mating, the axial tension force provided by the quick-connect clip 200 causes the stepped mating surface 101 to further compress the arc-shaped protrusion 301, resulting in a greater elastic deformation of the arc-shaped protrusion 301. The contact pressure between the arc-shaped protrusion 301 and the stepped mating surface 101 increases, the contact area increases, and the sealing performance is enhanced.

[0101] In this embodiment, the self-locking force of the quick-connect buckle 200, i.e., the axial locking force it can provide after snapping, is ≥50N. Optionally, the axial locking force is 50N to 100N. Within this locking force range, the arc-shaped protrusion 301 is compressed to a predetermined compression amount. Optionally, the preset compression amount is 30% to 50% of the original height of the arc-shaped protrusion 301. This generates sufficient sealing contact pressure without causing elastic fatigue or permanent deformation of the sealing assembly 300 due to excessive compression.

[0102] Optionally, when there are multiple quick-connect components, first lock two quick-connect clips 200 in opposite positions, then lock another pair of quick-connect clips 200 in opposite positions, and so on. Alternating diagonal locking ensures that the modular layered branch duct 100 receives uniform axial pressure, preventing the modular layered branch duct 100 from becoming misaligned due to locking on one side first, which would result in uneven pressure distribution between the stepped mating surface 101 and the arc-shaped protrusion 301 of the sealing component 300.

[0103] Optionally, when there are multiple quick-connect components, each quick-connect buckle 200 can be initially engaged to a semi-locked state, i.e., the elastic hook has not yet fully passed the locking protrusion, and then each quick-connect buckle 200 can be fully pressed to the self-locking state one by one. During the initial engagement stage, it can be observed whether the circumferential gap between the modular layered branch air duct 100 and the battery compartment air inlet 400 is uniform. If there is a deviation, it can be finely adjusted before fully locking.

[0104] When it is necessary to disassemble the modular layered branch air duct 100, press the snap-on end of the quick-connect clip 200 to cause the elastic hook to deform elastically and disengage from the locking boss, thus releasing the self-locking mechanism. Then, pull the quick-connect clip 200 outward to the open position to separate the snap-on end from the snap-on connector 402. After releasing all quick-connect clips 200, slowly pull the modular layered branch air duct 100 axially out of the battery compartment air inlet 400. During the pulling process, care should be taken to maintain axial force to avoid deflection that could cause the stepped mating surface 101 to scrape or shear against the arc-shaped protrusion 301 of the sealing assembly 300, damaging the sealing assembly 300.

[0105] In an optional embodiment, when it is necessary to replace the battery pack of a different specification, the self-locking state of the quick-connect buckle 200 is released, and the modular layered branch air duct 100 is disassembled from the battery compartment air inlet 400; another modular layered branch air duct 100 with the specification length adapted to the replaced battery pack is determined, and the process returns to the step of controlling the sealing assembly 300 to be embedded in the annular slot 401 of the battery compartment air inlet 400 and subsequent steps.

[0106] Release the self-locking mechanism of each quick-connect clip 200 one by one, separating the clip end from the clip connecting seat 402. When releasing the self-locking mechanism, be careful to hold the quick-connect clip 200 and release it slowly to avoid the quick-connect clip 200 popping up and injuring the operator or surrounding equipment due to the sudden disengagement of the elastic hook. After releasing all quick-connect clips 200, pull the cylinder of the modular layered branch air duct 100 axially out of the battery compartment air inlet 400. During the pulling process, observe whether the sealing assembly 300 is pulled out along with the modular layered branch air duct 100. If the sealing assembly 300 is pulled out, remove it from the modular layered branch air duct 100 in time, check whether the sealing assembly 300 is intact, if intact, reinstall it in the annular groove 401 for backup, if damaged, replace it with a new sealing assembly 300. If the modular layered branch air duct 100 is fastened to the main air duct, the connection at the end of the main air duct must be removed first, and then the modular layered branch air duct 100 can be pulled out.

[0107] Based on the dimensions and specifications of the newly replaced battery pack, a new modular layered branch air duct 100 of the corresponding length is selected from the pre-prepared series of modular layered branch air ducts 100. Different models of the series of modular layered branch air ducts 100 vary in length, such as 300mm, 400mm, 500mm, and 600mm, but the dimensions and shape of the stepped docking surface 101 at their ends are exactly the same, as is the interface structure with the main air duct.

[0108] After selecting the new modular layered branch air duct 100, first check the surface quality of its stepped mating surface 101 to confirm that there are no scratches, deformations or foreign objects attached, and then repeat the installation steps S10 to S20.

[0109] When replacing the modular layered branch duct 100, the condition of the sealing assembly 300 must be assessed to determine whether it should be reused or replaced. If the sealing assembly 300 is in good condition, without cracks, permanent deformation, hardening, or foreign object embedding, and the installation time has not exceeded the recommended service life, it can continue to be reused. If the sealing assembly 300 exhibits any of the following conditions, it should be replaced immediately: if the surface has cracks or scratches exceeding a depth of, for example, 0.5 mm; the arc-shaped protrusion 301 has undergone permanent crushing deformation, with its height reduced by more than a preset ratio of, for example, 20% of the original height; the material has hardened; or the recommended service life has been exceeded.

[0110] Taking a specific battery pack specification as an example, the original energy storage cabinet installed a 32650 battery pack manufactured by Manufacturer A, with a battery pack height of 400mm and a corresponding modular layered branch air duct 100 length of 500mm. It now needs to be replaced with a 21700 battery pack manufactured by Manufacturer B, with a battery pack height of 300mm, 100mm shorter than the original battery pack. Therefore, a new modular layered branch air duct 100 with a length of 400mm should be selected, and the replacement can be carried out according to the above steps. Because the new battery pack is shorter, its battery compartment air inlet 400 is 100mm closer to the main air duct than before, and the shorter modular layered branch air duct 100 can perfectly match the positional change. As another example, the original energy storage cabinet installed a custom-sized battery pack manufactured by Manufacturer C, and it now needs to be replaced with a standard-sized battery pack manufactured by Manufacturer D, increasing the battery pack height by 150mm. In this case, a new modular layered branch air duct 100 with an increased length of 150mm should be selected for replacement.

[0111] By releasing the self-locking state of the quick-connect clip 200, the modular layered branch air duct 100 can be quickly and non-destructively disassembled. When replacing battery packs of different specifications, another modular layered branch air duct 100 of suitable length can be flexibly selected for standardized reassembly, improving the maintainability, replaceability, and modularity of the sealing adapter. This not only shortens the air duct modification cycle during battery pack upgrades or maintenance and reduces the overall replacement cost caused by changes in battery specifications, but also ensures that the sealing performance after replacement is consistent with the initial assembly by repeatedly performing standard assembly steps such as embedding, plugging and mating of the sealing component 300 and clip self-locking. This ensures the long-term stable airtight sealing quality and ventilation and heat dissipation reliability of battery compartments of different specifications, extends the service life of the energy storage cabinet, and improves its adaptability throughout its entire life cycle.

[0112] In the technical solution of this embodiment, after the modular layered branch air duct 100 and the battery compartment air inlet interface 400 are connected, the quick-connect buckle 200 is controlled to engage with the buckle connector 402 and pressed into a self-locking state, thereby achieving a rapid mechanical locking between the modular layered branch air duct 100 and the battery compartment air inlet interface 400. A firm connection can be completed without the need for additional tools, which significantly improves assembly efficiency and ease of operation. At the same time, the self-locking function can effectively resist vibration and external force interference during the operation of the energy storage cabinet, preventing the modular layered branch air duct 100 and the battery compartment air inlet interface 400 from loosening or displacement, thereby ensuring the continuous and stable axial compression state of the sealing component 300, ensuring the long-term reliability of the airtight seal, and further improving the overall structural stability and safety of the sealing adapter.
