Description

Technical Field

[0001] This application relates to the field of photovoltaic energy storage technology, and in particular to a housing for an energy storage device. Background Technology

[0002] With the widespread application of small rooftop and balcony photovoltaic systems in cities and residential areas, the demand for balcony photovoltaic energy storage systems continues to grow. As the application scope of these systems expands, the performance requirements for energy storage equipment are also increasing, particularly in terms of IP protection, appearance design, and heat dissipation, where requirements are becoming increasingly stringent. Traditional energy storage devices typically have photovoltaic terminals located on one side of the device, supporting only a single-sided connection to external photovoltaic panels. While this terminal layout meets basic connection needs, it has limitations in functionality and ease of installation.

[0003] Currently, energy storage equipment casings employ a split design, comprising three independent parts: a top cover, a front shell, and a rear shell. Battery modules are typically installed in the lower shell, which consists of the front and rear shells, and finally sealed by the top cover. To ensure airtightness, seals are installed at the joint surfaces and secured with multiple screws. However, while this design achieves basic sealing, the assembly process is complex and relies heavily on manual labor, resulting in low production efficiency and high costs. Especially in confined spaces such as balconies, the traditional structure occupies side space, affecting aesthetics and increasing installation difficulty. Furthermore, side openings pose challenges to sealing and structural stability, and exposed seams and screw holes further disrupt the product's visual consistency, failing to meet the requirements of modern, simple, and aesthetically pleasing design.

[0004] Therefore, there is an urgent need for an innovative housing structure that aims to improve assembly efficiency, optimize the layout of photovoltaic terminals, improve appearance design, and effectively solve problems such as poor sealing and inconvenient installation in existing designs. Utility Model Content

[0005] In order to solve the problems of low assembly efficiency, poor sealing reliability, poor appearance consistency and space and sealing issues of side-mounted terminals in the existing split battery pack shell, this application provides an energy storage device shell.

[0006] The energy storage device housing provided in this application adopts the following technical solution:

[0007] An energy storage device housing, comprising:

[0008] The front and rear boxes are detachably connected;

[0009] Photovoltaic terminal group located on the back of the rear housing;

[0010] The rear housing is equipped with a three-dimensional sealing structure, and forms multiple sealing interfaces with the front housing through the three-dimensional sealing structure.

[0011] By adopting the above technical solutions, the detachable connection design makes the assembly process of the front and rear housings simpler and more efficient. Operators can quickly complete the assembly, reducing the cumbersome steps in the traditional split battery pack casing design and improving overall production efficiency. Especially in large-scale production environments, this design can significantly reduce assembly time and labor costs. In addition, the introduction of a three-dimensional sealing structure solves the problem of poor sealing in traditional designs. The three-dimensional sealing structure ensures the sealing performance of the equipment through the design of multiple sealing interfaces. This multi-layer sealing structure effectively prevents the intrusion of external substances such as moisture and dust. Especially in outdoor environments, the equipment can maintain stability and reliability for a longer period of time, extending its service life. The design of the photovoltaic terminal group on the back of the rear housing avoids the disadvantage of traditional side-mounted terminals occupying too much space, making the equipment more flexible during installation and improving the aesthetics of the equipment. It ensures that the appearance of the equipment is simpler and more uniform, meeting the requirements of modern users for the appearance of energy storage equipment.

[0012] In one specific implementation, the three-dimensional sealing structure includes at least one planar sealing surface and at least one three-dimensional sealing surface.

[0013] By adopting the above technical solution, the three-dimensional sealing structure forms a multi-layer sealing system through the combination of planar sealing surfaces and three-dimensional sealing surfaces. Furthermore, since the sealing structure extends continuously along the periphery of the rear housing to form a closed-loop seal, the pressure between the sealing interfaces is evenly distributed, avoiding the problem of incomplete sealing that may be caused by a single sealing point. This prevents the intrusion of external substances such as moisture and dust, extends the service life, and ensures the stability of equipment operation.

[0014] In one specific implementation, a sealing ring is also included, wherein the rear housing has a sealing groove arranged circumferentially thereon, and the sealing ring is embedded in the sealing groove.

[0015] By adopting the above technical solution and utilizing the design of the sealing ring, an additional sealing barrier is formed after the sealing ring is embedded in the sealing groove. This design not only increases the contact area of ​​the sealing surface, but also enhances the overall elasticity of the sealing structure, further preventing external substances such as air, moisture, and dust from entering the interior of the enclosure, thereby improving the service life and reliability of the equipment.

[0016] In one specific implementation, a cover plate is also included, which is detachably connected to the rear housing and covers the photovoltaic terminal group.

[0017] By adopting the above technical solution and utilizing the cover plate design, the photovoltaic terminal group can be hidden, making the overall appearance cleaner and more beautiful. This not only avoids the terminal group from being affected by the external environment, but also improves the safety of the equipment and prevents electrical safety hazards such as electric shock. The detachable connection between the cover plate and the rear housing makes it easy to open the cover plate for inspection, maintenance or replacement of the photovoltaic terminal group.

[0018] In one specific implementation, the back of the rear housing is provided with a through hole communicating with its interior, and the photovoltaic terminal group is installed on the rear housing through the through hole.

[0019] By adopting the above technical solution, the photovoltaic terminal group is installed on the back of the rear housing through through holes, which can save the external space of the equipment to the maximum extent, avoid the problem of the terminal group occupying the side space in the traditional design, ensure the appearance of the equipment is simple and uniform, improve the overall aesthetics, and facilitate the double-sided wiring of the energy storage equipment; in addition, the photovoltaic terminal group is fixed to the rear housing through through holes, ensuring that the terminal group is not easy to loosen or fall off during use.

[0020] In one specific implementation, a circuit board is provided inside the rear housing, and the photovoltaic terminal group is connected to the circuit board through the through hole.

[0021] By adopting the above technical solution, the design of the rear enclosure circuit board allows electrical components to be connected to other circuits through the photovoltaic terminal group. The through holes serve as connection channels, and the tight connection between the terminal group and the circuit inside the rear enclosure ensures that electrical signals or power can be transmitted to the circuit board through the photovoltaic terminal group. This helps to simplify the circuit layout and ensures smooth transmission of current or signals.

[0022] In one specific implementation, the outer wall of the rear housing is provided with heat dissipation fins, and the heat dissipation fins are correspondingly arranged with the circuit board.

[0023] By adopting the above technical solution, the main function of the heat dissipation fins is to increase the heat exchange area on the surface of the rear housing, thereby improving heat dissipation efficiency. Through this layout design, heat is transferred from the heat source circuit board in the circuit to the heat dissipation fins, enabling the fins to carry away heat more efficiently. The close cooperation between the heat dissipation fins and the circuit board achieves efficient heat management and prevents local overheating.

[0024] In one specific implementation, the front housing and the rear housing are connected by bolts.

[0025] By adopting the above technical solution and using bolts, the front and rear boxes can form a tight and stable connection. The tightening force of the bolts can effectively prevent the boxes from loosening due to vibration or external force during use, thereby ensuring the stability of the box structure.

[0026] In one specific implementation, the joint between the front housing and the rear housing is provided with a mutually cooperating positioning structure.

[0027] By adopting the above technical solution, the positioning structure design can ensure that the front and rear housings can be accurately aligned during assembly, thereby avoiding deviations or asymmetries. Furthermore, the positioning structure can greatly simplify the installation process of the front and rear housings, making it more efficient and accurate. This not only improves installation efficiency but also ensures the safety and durability of the equipment during use.

[0028] In summary, the beneficial technical effects of this application are as follows: This solution provides a structurally sound and fully functional energy storage device housing design that balances efficient assembly, excellent sealing, safety, and aesthetics, meeting the various needs of modern energy storage devices; by adopting a detachable front and rear housing design, combined with a three-dimensional sealing structure, the efficiency and reliability of the energy storage device during assembly are ensured; this design simplifies the assembly process, reduces labor costs, and significantly improves production efficiency, especially in large-scale production environments.

[0029] The three-dimensional sealing structure effectively solves the sealing problems in traditional designs through the design of multiple sealing interfaces, preventing the intrusion of external substances such as moisture and dust, and ensuring the stability and long service life of the equipment in harsh environments. Furthermore, the design of the sealing ring enhances the sealing performance, preventing external substances from entering the cabinet and improving the reliability and service life of the equipment.

[0030] The rear of the enclosure is pre-installed with photovoltaic terminal blocks, which saves space and improves the aesthetics of the equipment while ensuring a smooth connection with the photovoltaic system. The photovoltaic terminal blocks are installed on the back, which effectively saves space and ensures the stability of the photovoltaic connection. The heat dissipation fins enhance heat dissipation, prevent the equipment from overheating, and ensure the normal operation of the circuit board. Attached Figure Description

Detailed Implementation

[0036] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0037] This application discloses an energy storage device housing, the structural design of which aims to improve the device's sealing performance, ease of installation, aesthetic appearance, and functionality, and is particularly suitable for energy storage devices in photovoltaic systems.

[0038] Reference Figure 1 An energy storage device housing includes a front housing 1 and a rear housing 3, which are connected by a detachable connection to form an integrated housing structure.

[0039] The rear housing 3 is provided with a three-dimensional sealing structure 9. The rear housing 3 cooperates with the front housing 1 through the three-dimensional sealing structure 9 to form a multi-layer sealing interface. In this embodiment, the rear housing 3 forms a combined planar and three-dimensional sealing interface with the front housing 1 through the three-dimensional sealing structure 9, ensuring that the equipment has excellent sealing performance during use.

[0040] The rear housing 3 has a photovoltaic terminal group 5 on the back; the rear installation design can avoid the disadvantage of traditional side-mounted terminals taking up too much space, making the equipment more flexible during installation and also improving the aesthetics of the equipment.

[0041] During assembly, the operator first aligns the front housing 1 and the rear housing 3, and connects the two parts through a detachable connection. At this time, the front housing 1 and the rear housing 3 form a multi-seal interface through the three-dimensional sealing structure 9 to ensure a reliable sealing effect between the two parts. During this process, the photovoltaic terminal group 5 is pre-installed on the back of the rear housing 3. During the assembly process, the position of the photovoltaic terminal group 5 is fixed to ensure a smooth connection with the external photovoltaic system.

[0042] In this process, the detachable connection design makes the assembly of the front casing 1 and the rear casing 3 simpler and more efficient. Operators can quickly complete the assembly, reducing the cumbersome steps in the traditional split battery pack casing design, improving overall production efficiency, and reducing assembly time and labor costs. At the same time, the design of the three-dimensional sealing structure 9 can solve the problem of poor sealing in the traditional design. The three-dimensional sealing structure 9, through the design of multiple sealing interfaces, ensures the sealing performance of the equipment, prevents the intrusion of external substances such as moisture and dust, maintains the stability and reliability of the equipment, and extends its service life.

[0043] Reference Figure 1 and Figure 2 To improve the sealing performance of the equipment, this embodiment adopts a three-dimensional sealing structure 9, which includes at least one planar sealing surface 11 and at least one three-dimensional sealing surface 10. The planar sealing surface 11 has a single planar shape, and the three-dimensional sealing surface 10 has a three-dimensional sealing surface with a different shape than the planar sealing surface 11, such as an inclined surface, a convex surface, or a concave surface. In this embodiment, the planar sealing surface 11 and the three-dimensional sealing surface 10 extend continuously along the periphery of the rear housing 3 to form a closed-loop sealing structure. The planar sealing surface 11 and the three-dimensional sealing surface 10 abut against the front housing 1 to seal, ensuring that the equipment can effectively prevent interference from the external environment during use and provide excellent protection.

[0044] The design of the three-dimensional sealing structure 9 not only includes a single planar sealing surface 11 and a three-dimensional sealing surface 10, but can also adopt a combination of multiple sealing surfaces as needed. Specifically, the three-dimensional sealing structure 9 includes, but is not limited to: one planar sealing surface 11 and one three-dimensional sealing surface 10, one planar sealing surface 11 and two three-dimensional sealing surfaces 10, and one planar sealing surface 11 and three three-dimensional sealing surfaces 10. In this embodiment, the three-dimensional sealing structure 9 adopts a design of one planar sealing surface 11 and one three-dimensional sealing surface 10. This design can not only adapt to the sealing requirements of different devices, but also effectively solve the sealing challenges in different working environments.

[0045] In other embodiments, other combinations of planar sealing surfaces 11 and three-dimensional sealing surfaces 10 can be flexibly selected according to the specific needs of the equipment and environmental conditions. Through combination design, the three-dimensional sealing structure 9 can form a multi-layer sealing system, thereby preventing the equipment circuit board 6 from directly contacting the external environment in all directions, ensuring the efficient operation and long-term stability of the equipment.

[0046] The combination of planar sealing surface 11 and three-dimensional sealing surface 10 forms a multi-layer sealing system, ensuring uniform pressure distribution between sealing interfaces and avoiding the problem of incomplete sealing that may exist in a single sealing point in traditional designs. Through the closed-loop sealing design, it can effectively prevent the intrusion of external substances such as moisture, dust, and sand. Especially in harsh environments, the equipment can maintain excellent sealing performance and ensure stable operation of the equipment.

[0047] Reference Figure 1 and Figure 2 To further enhance the sealing effect, the sealing structure design also includes a sealing ring 2. The rear housing 3 is provided with a sealing groove arranged along its circumference. The sealing groove is located on the planar sealing surface 11 and the three-dimensional sealing surface 10. The sealing ring 2 is embedded in the sealing groove to form a tighter and more effective sealing system. The design of the sealing ring 2 includes, but is not limited to, a silicone hollow sealing ring 2. In addition, foaming adhesive or direct application of wet adhesive can be used to fill the sealing groove to form a highly efficient sealing interface.

[0048] In this embodiment, the sealing ring 2 is a hollow silicone sealing ring 2. This material has excellent elasticity and durability, and can adapt to changes in different temperatures and environments. At the same time, the hollow silicone sealing ring 2 has good anti-aging properties and corrosion resistance, which can effectively extend the service life of the equipment. In addition, other embodiments of this invention can also use sealing rings 2 made of other materials, such as foam sealing rings 2 or wet adhesive forms. These forms have good filling properties, which can better fill the tiny gaps at the connection parts of the equipment and further improve the sealing effect.

[0049] During the assembly of the front housing 1 and the rear housing 3, the sealing ring 2 abuts against the edge of the front housing 1 and is tightly fitted by interference sealing. The addition of the sealing ring 2 can form an additional barrier at the connection between the front housing 1 and the rear housing 3, avoiding the problem of reduced sealing performance due to structural deformation or external force, enhancing the equipment's protection against external substances such as air, moisture and dust, improving the service life and reliability of the equipment, and ensuring that the equipment always maintains a good sealing condition during use.

[0050] The front housing 1 and the rear housing 3 are connected by a number of bolts 4. In this embodiment, the bolts 4 first pass through the rear housing 3 and then insert into the front housing 1 to be threaded and fixed to the front housing 1, so that a stable and tight connection is formed between the two. In this embodiment, the installation positions of the bolts 4 are located outside the sealing groove, and the installation positions of the bolts 4 avoid the sealing groove and the sealing ring 2, thereby avoiding interference between the bolts 4 and the sealing system.

[0051] The bolt 4 connection design can effectively prevent the front housing 1 and the rear housing 3 from loosening due to vibration or external force during use, ensuring the stability of the energy storage equipment shell structure. The bolt 4 connection is relatively simple in actual operation, making it easy for operators to install and disassemble quickly. At the same time, the bolt 4 tightening force can ensure that the equipment maintains a stable structure during use, avoiding damage to the equipment caused by external vibration or impact.

[0052] Reference Figure 1 and Figure 2 The rear housing 3 has a through hole 14 on its back that communicates with its interior. The photovoltaic terminal group 5 is fixed to the rear housing 3 through the through hole 14, ensuring that the photovoltaic terminal group 5 is securely installed. This design can save the external space of the equipment to the maximum extent and avoid the disadvantage of the terminal group occupying too much space in the traditional design, thereby improving the space utilization of the equipment.

[0053] With its rear-mounted design, the external space of the device is fully utilized, and the appearance is also more concise and unified, enhancing the overall aesthetics and meeting the aesthetic requirements of modern users for the appearance of energy storage devices. It also facilitates the routing of cables on both sides of the energy storage device. In addition, the design of the through hole 14 ensures that the photovoltaic terminal group 5 can be stably fixed during use, avoiding loosening or falling off due to vibration or other external forces, thus enhancing the reliability and safety of the device.

[0054] Reference Figure 2 and Figure 3 In this embodiment, a circuit board 6 is provided inside the rear housing 3. The photovoltaic terminal group 5 can also be connected to the circuit board 6 inside the rear housing 3 through the through hole 14. In this embodiment, the photovoltaic terminal group 5 is inserted and fixed in the through hole 14 and connected to the circuit board 6 for conduction through the wire 8. With this design, the through hole 14 can not only accommodate and fix the photovoltaic terminal group 5, but also ensure that electrical energy or electrical signals can be smoothly transmitted through the photovoltaic terminal group 5 to the circuit board 6 inside the rear housing 3, thereby realizing the effective connection between the photovoltaic terminal group 5 and the circuit board 6.

[0055] This connection method of photovoltaic terminal block 5 simplifies the circuit layout, avoids complex cable arrangement, and improves the power transmission efficiency of the entire system. This structural design not only ensures the stable transmission of electrical signals or power, but also facilitates left and right wiring in practical applications, making it easy to connect to photovoltaic panels and providing convenience for later maintenance and equipment expansion.

[0056] Reference Figure 4To further enhance the safety and aesthetics of the equipment, a cover plate 7 is also included. The cover plate 7 is detachably connected to the rear housing 3. The cover plate 7 can effectively cover the photovoltaic terminal group 5, thereby hiding the photovoltaic terminal group 5. This design not only makes the appearance of the energy storage equipment more concise and neat, avoiding exposed electrical components and improving the overall aesthetics of the equipment, but also reduces the direct impact of the external environment on the photovoltaic terminal group 5, effectively preventing dust, moisture, foreign objects or other potential external factors from damaging the terminal group.

[0057] In addition, the detachable connection design between the cover plate 7 and the rear housing 3 makes the maintenance and inspection process more convenient. When it is necessary to inspect, maintain or replace the photovoltaic terminal group 5, the staff can easily access the terminal group by simply removing the cover plate 7, which improves the maintainability of the equipment, reduces the complexity and time of operation, and makes daily maintenance work more efficient.

[0058] Reference Figure 2 To ensure accurate docking of the front box 1 and the rear box 3, a positioning structure 13 is provided at the joint of the front box 1 and the rear box 3. In this embodiment, the positioning structure 13 includes a positioning post on the rear box 3 and a positioning groove on the front box 1. During the assembly process, the positioning post will be accurately inserted into the positioning groove to form a firm connection. This design provides accurate guidance during the assembly process, so that the front and rear boxes 3 can be easily docked during assembly, avoiding deviations or asymmetries caused by inaccurate docking.

[0059] The positioning structure 13 is designed to provide accurate guidance during assembly, ensuring that the front housing 1 and the rear housing 3 achieve optimal docking during assembly, avoiding deviations or asymmetries, thereby improving the sealing performance and structural stability of the equipment. Furthermore, the positioning structure 13 simplifies the installation process of the front and rear housings 3. Due to the cooperation between the positioning column and the positioning groove, assemblers do not need to worry about errors during docking, making the operation simpler and faster. This not only improves assembly efficiency and reduces working hours, but also reduces the error rate during manual operation, thereby further improving production efficiency.

[0060] Reference Figure 1To improve the heat dissipation efficiency of the equipment, heat dissipation fins 12 are provided on the outer wall of the rear housing 3, and the heat dissipation fins 12 are correspondingly arranged with the circuit board 6. The design of the heat dissipation fins 12 not only focuses on improving the heat dissipation performance of the equipment, but also optimizes the overall thermal management system of the equipment. The main function of the heat dissipation fins 12 is to increase the heat exchange area on the surface of the rear housing 3, enhance the heat conduction between the equipment and the external environment, and thus effectively improve the heat dissipation efficiency of the equipment. Through this design, the heat generated by the circuit board 6 during operation can be quickly conducted to the heat dissipation fins 12. With the expansion structure of the heat dissipation fins 12, the heat can be released into the surrounding air through a larger surface area, significantly increasing the heat dissipation area and improving the heat dissipation effect.

[0061] The implementation principle of this application embodiment is as follows: by designing a structure in which the front box 1 and the rear box 3 can be detachably connected, and combined with the three-dimensional sealing structure 9, the assembly efficiency of the equipment is significantly improved; the detachable connection design allows operators to connect the two parts more quickly and efficiently during the assembly process, reducing the cumbersome steps in the traditional split battery pack shell design, thereby improving production efficiency and reducing labor costs.

[0062] Meanwhile, the design of the three-dimensional sealing structure 9, through the combination of multiple sealing surfaces, ensures that the equipment has excellent sealing performance, prevents the intrusion of external substances such as moisture and dust, improves the reliability and stability of the equipment, and extends its service life. The sealing structure also adopts the design of sealing ring 2 to increase the sealing effect, further improve the sealing performance, and avoid the problem of poor sealing in traditional designs.

[0063] By placing the photovoltaic terminal group 5 on the back of the rear housing 3, the problem of excessive space occupation by traditional terminal designs is effectively solved, saving external space and improving the aesthetics of the equipment. It is also connected to the circuit board 6 through the through hole 14, simplifying circuit wiring. This design makes the equipment more compact and concise, meeting the aesthetic requirements of modern users. In addition, the photovoltaic terminal group 5 is protected by the cover plate 7, which not only prevents external factors from damaging the terminals but also improves the aesthetics of the equipment. The overall solution not only optimizes the layout of the photovoltaic terminals and improves the space utilization of the equipment but also enhances the protective performance and heat dissipation effect of the equipment, ensuring its stable operation in harsh environments.

[0064] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
