Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1:

[0020] This utility model provides a battery box, including an outer casing 1, an outer cover 2 fixedly installed on the outer casing 1, an air inlet 3 and an air outlet 4, a fan 5 fixedly installed on the outer casing 1, an inner casing 7 fixedly connected to the outer casing 1 via a buffer assembly 6, an inner cover 8 sealed on the inner casing 7, and a battery 9 sealed inside the inner casing 7, the inner wall of the outer casing 1 and the outer wall of the inner casing 7 forming an air duct 10, the air duct 10 connecting the air inlet 3 and the air outlet 4, a heat sink 11 fixedly installed on the inner casing 7 within the air duct 10, the buffer assembly 6 including an outer cylinder 12, a plug rod 13 and a buffer element 14, the outer cylinder 12 fixedly connected to the inner casing 7, the plug rod 13 fixedly connected to the outer casing 1, the outer cylinder 12 movably inserted into the plug rod 13, and the outer cylinder 12 fixedly connected to the buffer element 14. A buffer spring 15 is fixedly installed inside the outer cylinder 12, and the buffer spring 15 elastically abuts against the plug rod 13. The buffer component 14 is made of silicone rubber. The inner housing 7 is made of copper. A buffer plate 16 is provided between the outer cover 2 and the inner cover 8. The buffer plate 16 has structural holes 17 and is made of synthetic rubber.

[0021] An electrical cabinet includes battery compartments and a cabinet body, wherein one or more battery compartments are disposed within the cabinet body.

[0022] Through the above technical solution, the present invention has a battery 9 sealed inside the inner box 7, which serves as a waterproof and moisture-proof function. The outer box 1 is fixedly connected to the inner box 7 through a buffer assembly 6, which serves as a buffer for the inner box 7 when it is impacted, thus protecting the battery 9 inside the inner box 7. The inner wall of the outer box 1 and the outer wall of the inner box 7 form an air duct 10, which connects the air inlet 3 and the air outlet 4. The inner box 7 is fixedly installed with a heat sink 11 inside the air duct 10. The heat sink 11 is used to transfer the heat inside the inner box 7. The fan 5 draws cold air into the air inlet 3, passes through the heat sink 11 in the air duct 10, and then discharges it from the air outlet 4, thereby reducing the temperature of the heat sink 11 and thus reducing the temperature inside the inner box 7, preventing thermal runaway of the battery 9.

[0023] Example 2:

[0024] In this embodiment, the battery 9 housing adopts a double-layer housing structure design. The outer housing 1 and the inner housing 7 work together to achieve multiple layers of protection and efficient heat dissipation for the battery 9. The outer housing 1 serves as the main supporting structure, and an outer cover 2 is fixedly installed on its top to form a complete external protective shell. An air inlet 3 and an air outlet 4 are respectively provided on the side of the outer housing 1. A fan 5 is fixedly installed at the air inlet 3 to drive airflow. The inner housing 7 is fixedly connected to the inside of the outer housing 1 through a buffer assembly 6. An inner cover 8 is sealed on the top of the inner housing 7 to form a completely enclosed space for the battery 9.

[0025] The inner casing 7 features a sealed structure, housing 9 battery packs. This sealed structure effectively isolates external moisture and dust, protecting the batteries 9 from environmental influences. A surrounding air duct 10 is formed between the inner wall of the outer casing 1 and the outer wall of the inner casing 7. This air duct 10 connects the air inlet 3 and the exhaust vent 4, creating a complete airflow path. Multiple heat sinks 11 are fixedly installed on the outer surface of the inner casing 7, within the air duct 10. These heat sinks 11 are in close contact with the inner casing 7 wall, efficiently conducting the heat generated by the batteries 9.

[0026] The buffer assembly 6 adopts a combined structure of an outer cylinder 12, a plug rod 13, and a buffer element 14. The outer cylinder 12 is fixedly connected to the inner casing 7, and the plug rod 13 is fixedly connected to the outer casing 1; the two are connected by a movable plug-in method. The buffer element 14 is fixedly installed inside the outer cylinder 12. When subjected to external impact, the buffer element 14 can absorb and disperse the impact energy, effectively protecting the inner casing 7 and the battery 9 inside. This buffer structure can significantly reduce the mechanical stress transmitted to the battery 9 when it encounters vibration during transportation or use.

[0027] When the cooling system is working, fan 5 draws in cool external air through inlet 3. As the cool air flows along air duct 10, it exchanges heat with heat sink 11, carrying away the heat generated by battery 9. Finally, the hot air is exhausted from exhaust vent 4. The large-area design of heat sink 11 increases heat exchange efficiency, ensuring that the operating temperature of battery 9 remains within a safe range. Simultaneously, the double-layer casing structure completely isolates the cooling air duct 10 from battery 9, ensuring effective heat dissipation while preventing the influence of the external environment on battery 9.

[0028] The key to this embodiment lies in the elastic connection between the inner and outer casings 1 achieved through the buffer component 6, which ensures structural stability and provides excellent shock absorption. The heat dissipation system employs an external circulation design, with the heat dissipation duct 10 completely isolated from the battery 9, achieving both efficient heat dissipation and ensuring the battery 9's sealed protection. The sealed structure of the inner casing 7 effectively prevents moisture and dust intrusion, extending the battery 9's lifespan. The overall structural design is reasonable, balancing protection performance and heat dissipation efficiency, making it particularly suitable for applications with high safety requirements for the battery 9.

[0029] Example 3:

[0030] In this embodiment, a buffer spring 15 is fixedly installed inside the outer cylinder 12 of the battery 9 casing. The buffer spring 15 and the insertion rod 13 form an elastic contact structure. When the battery 9 casing is subjected to external impact or vibration, the impact force is first transmitted to the outer casing 1, and then transmitted to the buffer assembly 6 through the insertion rod 13. At this time, the insertion rod 13 undergoes relative displacement within the outer cylinder 12, compressing the buffer spring 15. The buffer spring 15 absorbs the impact energy through its own elastic deformation and stores some of the energy as elastic potential energy. As the impact force weakens, the buffer spring 15 releases the stored elastic potential energy, pushing the insertion rod 13 back to its original position, achieving a dynamic balance in the buffering effect.

[0031] The buffer spring 15 adopts a helical compression spring structure, with its axis aligned with the direction of movement of the insertion rod 13. This arrangement allows the spring to evenly withstand impact forces from all directions. When the insertion rod 13 slides within the outer cylinder 12, the spring's compression deformation is proportional to the magnitude of the impact force, creating a gradual buffering effect. The spring's pre-compression is precisely designed to ensure appropriate preload under normal operating conditions, neither hindering the free movement of the insertion rod 13 nor hindering its immediate buffering response.

[0032] During the operation of the battery 9 enclosure, the vibration generated by the fan 5 is transmitted to the buffer assembly 6 through the outer casing 1. The buffer spring 15 effectively absorbs these high-frequency, low-amplitude vibrations, preventing vibration energy from being transmitted to the inner casing 7. At the same time, the elastic properties of the spring can filter out vibrations within a specific frequency range, avoiding resonance with the internal structure of the battery 9. This dual buffering mechanism significantly improves the stability of the battery 9 during transportation and use.

[0033] When the battery compartment 9 is subjected to a significant impact, the compression stroke of the buffer spring 15 reaches its maximum value, at which point the spring's elastic force and the impact force are balanced. This design ensures sufficient buffering stroke while preventing rigid collisions. The spring's restoring characteristics ensure that the plug 13 can automatically reset, maintaining the normal operation of the buffer assembly 6. The entire process requires no manual intervention, achieving automated buffer protection.

[0034] The buffer spring 15 is fixedly connected to the outer cylinder 12 to ensure that the spring will not shift or twist during operation. The end of the insert rod 13 has a pressure-bearing surface that contacts the spring; this surface is specially treated to reduce frictional resistance. This structural design makes the buffering action smoother, reduces energy loss, and improves buffering efficiency. Simultaneously, the linear characteristics of the spring ensure a good proportional relationship between the buffering force and displacement, facilitating the prediction and control of the buffering effect.

[0035] During long-term use, the buffer spring 15 will undergo repeated compression-release cycles. The spring material used in this embodiment has excellent fatigue resistance and can maintain stable elastic characteristics. The fixed connection between the spring and the outer cylinder 12 is equipped with an anti-loosening structure to prevent the connection from loosening due to vibration. These design details together ensure the reliability of the buffer assembly 6 throughout the entire service life of the battery 9 compartment.

[0036] Example 4:

[0037] In this embodiment, the outer casing 1 and inner casing 7 of the battery 9 housing are flexibly connected by a buffer assembly 6, wherein the buffer element 14 is made of silicone rubber. Silicone rubber has excellent elastic deformation capability and damping characteristics. When the outer casing 1 is subjected to external impact or vibration, the silicone rubber buffer element 14 in the buffer assembly 6 can absorb and disperse the impact energy through its own elastic deformation. Specifically, the flexibility of the silicone rubber molecular chain allows it to undergo a large degree of deformation when subjected to force, and the friction between its molecules can convert mechanical energy into heat energy for dissipation, thereby effectively reducing the impact force transmitted to the inner casing 7.

[0038] During the operation of the battery 9 casing, the silicone rubber buffer 14 continuously provides cushioning. When the casing is subjected to vibrations from transportation or installation, the relative movement between the outer cylinder 12 and the insertion rod 13 is damped by the silicone rubber buffer 14. This damping effect comes from the viscoelastic properties unique to silicone rubber. Silicone rubber exhibits both the rapid recovery characteristics of an elastomer and the energy dissipation capacity of a viscous fluid under stress, allowing vibration energy to be effectively absorbed without being completely transferred to the inner casing 7.

[0039] The installation method of the silicone rubber buffer 14 ensures that its buffering performance is fully utilized. The buffer 14 is fixedly connected to the outer cylinder 12. When the insert rod 13 moves relative to the outer cylinder 12, the silicone rubber material is simultaneously subjected to compression and shearing. Under this combined stress state, the silicone rubber can maintain stable mechanical properties and will not exhibit significant stress relaxation or permanent deformation, ensuring the buffering effect during long-term use.

[0040] Even under varying temperature conditions, the silicone rubber buffer 14 maintains excellent cushioning performance. Silicone rubber has a wide operating temperature range, and its elastic modulus changes little with temperature, ensuring stable cushioning protection for the battery 9 casing under different ambient temperatures. Especially at high temperatures, silicone rubber does not exhibit significant softening like ordinary rubber, maintaining sufficient support and damping effect.

[0041] The chemical stability of silicone rubber also provides long-term reliable operation for the buffer assembly 6. Silicone rubber exhibits excellent resistance to environmental factors such as ozone and ultraviolet radiation, and is not prone to aging and cracking, thus extending the service life of the buffer assembly 6. Simultaneously, the chemical corrosion resistance of silicone rubber allows it to adapt to various complex working environments, and its performance will not degrade upon contact with gases or liquids within the enclosure.

[0042] In the heat dissipation system of the battery 9 casing, the silicone rubber buffer 14 also plays an important role in heat insulation. The low thermal conductivity of silicone rubber effectively blocks heat conduction between the outer casing 1 and the inner casing 7, preventing the external high-temperature environment from adversely affecting the temperature of the battery 9. This combination of heat insulation and buffering performance makes silicone rubber an ideal choice for the battery 9 casing buffer assembly 6.

[0043] The use of silicone rubber buffer 14 also simplifies the structural design of the battery 9 socket. Since silicone rubber combines elastic support and damping vibration reduction, there is no need for additional complex vibration damping mechanisms, making the buffer assembly 6 more compact and facilitating the miniaturization of the battery 9 socket. Furthermore, silicone rubber has good processability and can be manufactured into various shapes and sizes to meet the cushioning requirements of battery 9 sockets of different specifications.

[0044] Example 5:

[0045] The battery 9 housing in this embodiment comprises two parts: an outer casing 1 and an inner casing 7. The outer casing 1 is a metal frame structure, with an outer cover 2 fixedly installed on its top, forming a complete external protective shell. Air inlets 3 and exhaust vents 4 are respectively provided on both sides of the outer casing 1, and a forced ventilation fan 5 assembly is installed at the air inlet 3. The inner casing 7 is made of copper and is flexibly connected to the outer casing 1 via a buffer assembly 6. An inner cover 8 is sealed on the top of the inner casing 7, forming a completely enclosed space for the battery 9.

[0046] The copper material of the inner casing 7 has excellent thermal conductivity, enabling it to quickly conduct the heat generated by the battery 9 during operation to the casing surface. A surrounding air duct 10 structure is formed between the inner casing 7 and the outer casing 1, connecting the air inlet 3 and the exhaust outlet 4 to create a complete airflow circulation path. Multiple sets of copper heat sinks 11 are evenly arranged along the air duct 10 on the outer surface of the inner casing 7. These heat sinks 11 are integrally formed with the inner casing 7 body, ensuring good heat conduction.

[0047] The buffer assembly 6 adopts a three-stage shock absorption structure, including an outer cylinder 12, insert rods 13, and a buffer element 14. The outer cylinder 12 is welded and fixed to the four corners of the inner housing 7, while the insert rods 13 are fixed to the corresponding positions on the outer housing 1. The outer cylinder 12 and the insert rods 13 are connected by a clearance fit, with an elastic buffer element 14 placed between them. This structural design allows the inner housing 7 to generate a moderate displacement when subjected to external impact, absorbing the impact energy through the elastic deformation of the buffer element 14.

[0048] When battery 9 is operating, the heat generated is rapidly conducted to the surface of heat sink 11 through the copper inner casing 7. When fan 5 is running, external cool air enters through air inlet 3, flows along air duct 10 across the surface of heat sink 11, carries away heat, and is then exhausted through exhaust outlet 4. Due to the high thermal conductivity of copper, heat can be quickly transferred from battery 9 to heat sink 11, and then dissipated through forced convection, forming an efficient heat transfer path. At the same time, the copper inner casing 7 has good structural strength, effectively protecting the internal battery 9 from mechanical damage.

[0049] In this embodiment, the use of a copper inner casing 7 significantly improves overall heat dissipation efficiency. Copper's high thermal conductivity ensures rapid heat dissipation from the battery 9, and combined with a forced convection cooling system, effectively controls the battery 9's operating temperature. The buffer assembly 6 ensures effective protection of the copper inner casing 7 and its internal battery 9 under vibration or impact conditions. This structural design satisfies both heat dissipation requirements and battery 9 protection requirements, helping to extend the battery 9's lifespan and improve system safety.

[0050] Example 6:

[0051] In this embodiment, a buffer plate 16 is provided between the outer cover 2 and the inner cover 8 of the battery 9 casing. The buffer plate 16 is made of synthetic rubber and has good elasticity and cushioning performance. Multiple structural holes 17 are formed on the buffer plate 16 in a regular array, which ensures the overall structural strength of the buffer plate 16 while effectively reducing material usage. When the battery 9 casing is subjected to external impact, the buffer plate 16 can absorb part of the impact energy through its elastic deformation, reducing the vibration transmitted to the inner casing 7.

[0052] The structural holes 17 of the buffer plate 16 are designed with a honeycomb arrangement, which minimizes material usage while ensuring cushioning performance. The hole diameters of the structural holes 17 are optimized to ensure sufficient deformation space without affecting the overall strength of the buffer plate 16. Upon impact, the buffer plate 16 first undergoes elastic deformation, and the shape of the structural holes 17 changes accordingly, thereby absorbing impact energy. This design allows the buffer plate 16 to achieve material savings while maintaining good cushioning performance.

[0053] The buffer plate 16 is elastically connected to the outer cover 2 and the inner cover 8 to ensure that it can fully exert its cushioning effect when subjected to impact. The thickness of the buffer plate 16 is designed according to the actual application requirements to ensure sufficient cushioning performance without excessively increasing the overall thickness of the casing. Under normal operating conditions, the buffer plate 16 remains flat and will not affect the heat dissipation performance of the casing. When subjected to impact, the buffer plate 16 will undergo elastic deformation, dispersing the impact force through the deformation of the structural holes 17.

[0054] The synthetic rubber material of the buffer plate 16 has excellent aging resistance and can maintain its elasticity for a long time. The design of the structural holes 17 also takes into account heat dissipation requirements and will not hinder heat transfer inside the casing. When the casing is subjected to vibration, the buffer plate 16 can effectively absorb high-frequency vibrations, protecting the internal battery 9 from damage. The edges of the buffer plate 16 are designed with rounded corners to avoid stress concentration and extend service life.

[0055] The design of the structural holes 17 in the buffer plate 16 also considers ease of manufacturing, facilitating mass production. During the assembly of the insert box, the buffer plate 16 can be easily installed between the outer cover 2 and the inner cover 8. When maintenance is required, the buffer plate 16 can be removed and replaced individually without replacing the entire cover assembly. This design improves product reliability and reduces maintenance costs.

[0056] The performance of the buffer plate 16 has undergone rigorous testing to ensure excellent cushioning under various environmental conditions. The arrangement density of the structural holes 17 is adjusted according to the actual application scenario to achieve optimal material utilization while ensuring performance. The installation position of the buffer plate 16 has been precisely calculated to ensure maximum protection for the internal battery 9 assembly. This design allows the battery 9 housing to effectively protect the internal battery 9 when subjected to impact, extending the battery 9's lifespan.

[0057] Example 7:

[0058] The electrical cabinet in this embodiment mainly consists of a cabinet body and multiple 9-cell battery boxes housed within the cabinet. The cabinet body adopts a metal frame structure, possessing sufficient mechanical strength and protection level to provide a stable installation environment for the internal equipment. Standardized mounting rails are installed inside the cabinet, facilitating modular installation and maintenance of the 9-cell battery boxes. Multiple 9-cell battery boxes are arranged vertically in layers within the cabinet, with each box connected to the cabinet via a slide rail, enabling quick plug-in and unplugging operations.

[0059] Each battery pack (9 cells) adopts a double-layer casing structure design, with the outer casing (1) and inner casing (7) flexibly connected by a buffer assembly (6). The outer casing (1) is made of metal with an anti-corrosion surface treatment, providing high structural strength. Air inlets (3) and exhaust outlets (4) are located at the front and rear ends of the outer casing (1), respectively. An axial flow fan (5) is installed at the air inlet (3) for forced airflow. The inner casing (7) features a sealed design, housing 9 lithium battery packs. The inner cover (8) is tightly fitted to the inner casing (7) via a waterproof sealing ring, ensuring that the internal battery packs (9 cells) are unaffected by the external environment.

[0060] The buffer assembly 6 adopts a combined structure of an outer cylinder 12, insert rods 13, and buffer element 14. The outer cylinder 12 is fixed to the four corners of the inner casing 7, and the insert rods 13 are fixed to the corresponding positions on the outer casing 1. The two are elastically connected by the buffer element 14. The buffer element 14 uses rubber shock absorbers, which can effectively absorb vibrations and impacts from the outside. This design allows the inner casing 7 to remain relatively stable when subjected to external forces, avoiding mechanical damage to the internal battery pack 9.

[0061] The cooling system adopts a duct-type cooling structure. An annular airflow duct 10 is formed between the inner wall of the outer casing 1 and the outer wall of the inner casing 7, with aluminum alloy heat sinks 11 evenly arranged within the airflow duct 10. The heat sinks 11 are tightly bonded to the outer wall of the inner casing 7 using thermally conductive adhesive, efficiently conducting the heat generated by the battery packs 9. When the fan 5 starts, cool external air enters through the air inlet 3, flows along the airflow duct 10 across the surface of the heat sinks 11, carries away heat, and is then exhausted from the exhaust outlet 4, forming a continuous heat exchange cycle.

[0062] This electrical cabinet achieves multiple protection functions through a rational structural design. The double-layer enclosure structure ensures both physical protection for the nine battery packs and efficient heat dissipation. The buffer assembly 6 effectively isolates external vibrations, extending the lifespan of the nine batteries. The modular design facilitates system expansion and maintenance, allowing multiple modules to operate independently or in parallel. The cabinet provides overall protection and environmental isolation, enabling the entire energy storage system to operate safely and stably under various operating conditions.
