[0040] In the description of the embodiments of the present application, unless otherwise clearly specified and limited, technical terms such as "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal connection of two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0041] As described in the background technology, in a multi-energy power generation system, a control box needs to be configured outdoors to supply power and communicate with the electrical components of the entire system. In the prior art, the control box is usually a metal shell. Metal is placed outdoors for a long time and is easily corroded by air or rain, thereby rusting and being damaged. In addition, metal has conductive properties and is easily prone to safety hazards such as electric shock when placed outdoors.

[0042] In order to alleviate the problem that the metal shell is easily corroded and rusted and poses a safety hazard, the applicant has found that the metal shell can be replaced with a shell made of an electrically insulating material with a lower mass density. The electrically insulating material has a smaller dielectric constant and a stronger ability to block the electric field, making it less likely to cause leakage. In addition, electrically insulating materials such as plastics have stable performance and are not easily corroded or damaged, thereby extending the service life of the control box.

[0043] The overall weight of the control box made of metal shell is relatively heavy, so refer to Figure 1 When assembling the metal shell with the keel 200 of the external building, a fixing structure is set at the four corners of the control box. The fixing structures at the four corners are as follows: Figure 1 As shown in A in the figure, at least four installation positions are formed to stably fix the box body on the keel 200 of the external building. However, after the control box body is replaced with an electrically insulating material, the weight of the box body is reduced. If the original four-corner fixing structure of the box body is still used, the fixing process will be complicated and inefficient.

[0044] In order to solve the above problems, the present application provides a control box 100, see Figures 2 to 8 The control box 100 includes a box body 10 , a cover body 20 and a mounting member 50 .

[0045] One end of the box body 10 has an opening 16, and the box body 10 has a first direction F1, a second direction F2 and a third direction F3. The size of the box body 10 in the first direction F1 is greater than the size in the second direction F2. The plane intersecting the first direction F1 and the second direction F2 is parallel to the plane where the opening is located. The third direction F3 is perpendicular to the plane where the opening 16 is located. The box body 10 includes a bottom plate 11 and a first side plate 12. The bottom plate 11 is opposite to the opening 16, and the first side plate 12 extends along the third direction F3 and is surrounded by the edge of the bottom plate 11.

[0046] The cover 20 covers the opening 16, and the cover 20 and the box body 10 enclose an electric control space 30. The mounting member 50 is fixed on the first side plate 12, and the mounting member is symmetrically distributed on opposite sides of the box body 10. The control box body 100 is made of electrically insulating material.

[0047] The box body 10 has three extension directions (respectively, the first direction F1, the second direction F2 and the third direction F3), so that the box body 10 forms a three-dimensional structure. Since the size of the box body 10 in the first direction F1 is larger than the size in the second direction F2, if the first direction F1 is defined as the length direction of the box body 10, the second direction F2 is the width direction, and the third direction F3 is the thickness direction of the box body 10. At this time, the thickness direction of the box body 10 is perpendicular to the plane where the opening 16 is located, and the plane where the first direction F1 and the second direction F2 intersect is perpendicular to the plane where the opening is located. The third direction F3 is perpendicular to the first direction F1, the second direction F2, and the plane where the two intersect, forming a rectangular box body 10. The control box body 100 is set as a rectangular parallelepiped, and the overall installation of the control box body 100 is achieved by fixing the box body 10 on the building.

[0048] The box body 10 may be a hollow structure with an opening 16 at one end, and the space inside the box body 10 is connected to the outside through the opening 16. The cover body 20 covers the opening 16 of the box body 10, so that after the cover body 20 is covered on the box body 10, the cover body 20 seals the internal space of the box body 10 and encloses it to form an electric control space 30. It can be understood that when the cover body 20 covers the opening 16 of the box body 10, it is sealed and connected to the first side plate 12 of the box body 10. The cover body 20 may be a plate-like structure, etc.

[0049] Electrical insulating materials refer to materials that can prevent the passage of electric current and thus produce insulating functions, including but not limited to plastics (such as polyvinyl chloride PVC, polyethylene PE, polypropylene PP, polycarbonate PC, etc.), insulating plastics) rubber (such as silicone rubber), resins, polymer materials (such as glass fiber reinforced plastics (FRP), paper composite insulating materials, etc., which are polymer materials formed by at least two composite materials), etc. Electrical insulating materials have good electrical breakdown resistance, aging resistance, and chemical corrosion resistance, thereby improving the electrical insulation performance and corrosion resistance of the control box 100.

[0050] In the prior art, a box body made of a metal shell needs to have a grounding wire connected to the shell for electric shock protection, but there is a risk of the grounding wire getting loose. Therefore, as described above, the present application uses a control box body made of an electrically insulating material, which is insulated and non-conductive, does not require additional grounding wires, and has no risk of getting loose, thus having a higher safety factor.

[0051] Furthermore, the control box 100 made of electrically insulating material has a lower mass density and is relatively lighter than metal. Therefore, when the control box 100 needs to be installed on an external building, if the original four-corner fixing structure of the box is used, not only will the fixing be complicated, but there will also be too many fixing positions, thereby reducing efficiency.

[0052] Therefore, the present application provides a mounting member 50 on the box body 10 for connecting the control box body 100 to an external structure, and the mounting member 50 is fixed on the first side panel 12 and symmetrically distributed on opposite sides of the box body 10, thereby forming two mutually symmetrical mounting and fixing positions on the outside of the box body 10. When the control box body 100 is assembled with the keel 200 of the external building, it is only necessary to fix these two mounting and fixing positions, and since the two mounting members 50 are symmetrical, the box body 10 as a whole is evenly stressed.

[0053] In this way, the present application can quickly fix the control box 100 through two symmetrical fixing positions, and ensure the symmetry and stability of the installation of the control box 100, and the assembly is simple and efficient.

[0054] Also, see Figure 1 In a conventional metal shell, the four corner fixing structures A are respectively arranged on both sides of the metal shell and are installed and fixed with the two vertical keels 200. At this time, the mounting holes on the fixing structure A for fixing and assembling with the keels 200 need to be set according to the spacing between the two keels 200. If the spacing between the mounting holes on both sides is inconsistent with the two vertical keels 200, the fixing structures A on both sides cannot be fixed to the two keels 200 at the same time. At this time, if the metal shell needs to be fixed, it is also necessary to additionally set a horizontal mounting accessory perpendicular to the keel 200 to meet the fixing requirements, which makes the assembly more complicated and affects the assembly efficiency.

[0055] In this application, see Figure 5 , mounting members 50 are arranged on opposite sides of the box body 10, so that two mounting members 50 can be connected to a vertical keel 200 at the same time without considering the lateral distance, so that the present application is suitable for the installation environment under a single keel 200, such as the single keel installation scenario of a wooden villa, thereby improving the assembly efficiency and the assembly applicability.

[0056] In one embodiment, the electric control space 30 enclosed between the cover body 20 and the box body 10 is suitable for accommodating electric control components, which include: at least one of: a circuit breaker, a contactor, a controller, a busbar device, a data acquisition device, and a communication device.

[0057] In actual engineering applications, suitable electronic control components can be selected so that the control box 100 can be used as a photovoltaic junction box, or a power distribution control box, or an off-grid control box, etc., so as to meet different usage requirements. The specific number and type of electronic control components are not specifically limited in this application.

[0058] In one embodiment, the mounting member 50 includes a first mounting member 51 and a second mounting member 52, the first side panel 12 includes an upper side panel 12a and a lower side panel 12b that are opposite to each other along the first direction F1, the first mounting member 51 is fixed to the middle position of the upper side panel 12a in the second direction F2, and the second mounting member 52 is fixed to the middle position of the lower side panel 12b in the second direction F2.

[0059] Specifically, see Figure 2 The box body 10 has a first geometric center line FL1 passing through its geometric center and parallel to the second direction F2, and a second geometric center line FL2 passing through the geometric center and parallel to the first direction. With the first geometric center line as the reference line FL1, the upper side plate 12a and the lower side plate 12b are symmetrically distributed, and the first mounting member 51 and the second mounting member 52 are symmetrically distributed. In addition, since the first mounting member 51 is arranged at the middle position of the upper side plate 12a in the second direction F2, and the second mounting member 52 is arranged at the middle position of the lower side plate 12b in the second direction F2, at the same time, the first mounting member 51 and the second mounting member 52 are arranged along the second geometric center line FL2.

[0060] During assembly, when the first mounting member 51 is fixed to the external building, since the second mounting member 52 is arranged at a central and symmetrical position with the external building, after the second mounting member 52 is fixed, the entire control box 100 can remain vertical (such as along the direction of gravity), thereby avoiding installation errors such as skewing of the control box 100 after installation.

[0061] Optionally, the first mounting member 51 and the second mounting member 52 may both be plate-shaped structures, so that the control box 100 can be vertically mounted on the building along the gravity direction from two fixed positions on both sides of the length direction.

[0062] Further, the mounting member 50 is fixed to one side of the first side plate 12 in the third direction F3 close to the bottom plate 11. Specifically, the first mounting member 51 is fixed to one side of the upper side plate 12a in the third direction F3 close to the bottom plate 11, and the second mounting member 52 is fixed to one side of the lower side plate 12b in the third direction F3 close to the bottom plate 11, and the first mounting member 51 and the second mounting member 52 are opposite to each other in the first direction F1.

[0063] The upper side plate 12a extends along the third direction F3, and one end extends to the opening 16, and the other side extends to connect with the bottom plate 11. Similarly, the lower side plate 12b extends along the third direction F3, and one end extends to the opening 16, and the other side extends to connect with the bottom plate 11. The first mounting member 51 is arranged on the side of the upper side plate 12a close to the bottom plate 11 and away from the opening 16, and the second mounting member 52 is arranged on the side of the lower side plate 12b close to the bottom plate 11 and away from the opening 16. In this way, when the mounting member 50 is fixed to the keel 200 of the external building, the bottom plate 11 of the box body 10 is also closer to the keel 200, and the bottom plate 11 is more in line with the building surface, so as to facilitate the installation and fixation of the control box body 100.

[0064] In one embodiment, the mounting member 50 is integrally formed with the box body 10 by injection molding. This manufacturing method can provide the mounting member 50 with better durability and stability, and can also improve the production efficiency of the control box body 100. Through integral injection molding, the problem of connection strength caused by the later assembly and welding of the mounting member 50 and the box body 10 is avoided, thereby improving the connection strength between the mounting member 50 and the box body 10, and then enhancing the fixing effect of the control box body 100.

[0065] Specifically, the mounting member 50 (including the first mounting member 51 and the second mounting member 52) can be any structure such as a connecting frame, a connecting plate, etc., on which a fixed mounting position directly matched with the building is provided, so as to facilitate installation and removal with an external building such as the keel 200.

[0066] In one embodiment, the mounting member 50 includes at least one mounting hole 50 a , and the mounting hole 50 a is opened along the third direction F3 .

[0067] Correspondingly, the external structure is also provided with a hole-shaped structure, and the mounting member 50 is fixed to the external structure through an additional fastening structure that passes through the hole-shaped structure and the mounting hole 50a on the external structure. Specifically, the fastening structure and the mounting hole 50a can be threaded or bolt-nut fastening. It can be understood that both the first mounting member 51 and the second mounting member 52 are provided with mounting holes 50a.

[0068] In this way, the mounting member 50 can be more stably connected to the external structure, and a more flexible installation method is provided to improve work efficiency. During later maintenance, the control box 100 can be disassembled by simply removing the fastening structure, thereby reducing production costs and maintenance costs.

[0069] It should be noted that during the design and manufacturing process, the size and position of the mounting hole 50a need to be precisely controlled to ensure that it can be stably connected to the external structure.

[0070] In other embodiments, the mounting member 50 may also be provided with a protruding structure, and the protruding structure may be passed through the hole structure of the external structure for fixation, thereby facilitating connection and improving assembly efficiency.

[0071] It can be understood that the multiple mounting holes 50a can be opened in a circular shape or in a waist-shaped hole, and the present application does not make any limitation thereto.

[0072] In one embodiment, the mounting member 50 includes at least two mounting holes 50a arranged along the second direction F2, each mounting hole 50a is opened along the third direction F3, and some mounting holes 50a extend longitudinally along the second direction F2, and some mounting holes 50a extend longitudinally along the first direction F1.

[0073] Specifically, part of the mounting hole 50a is opened in a waist shape, and part of it extends longitudinally along the first direction F1, and the other part extends longitudinally along the second direction F2, thereby increasing the drilling size deviation capacity on the mounting member 50, facilitating construction, and thus improving the processing efficiency of the control box 100.

[0074] In one embodiment, see Figure 4 and Figures 6 to 8 The cover body 20 includes a panel 21 and a second side panel 22. The second side panel 22 is arranged around the edge of the panel 21 and extends along the third direction F3. The cover body 20 covers the box body 10 so that the bottom plate 11 and the panel 21 are opposite, the second side panel 22 and the first side panel 12 are abutted, or the second side panel 22 covers at least part of the first side panel 12 of the box body 10, thereby ensuring the sealing of the electric control space 30.

[0075] In one embodiment, the thickness of the box body 10 and / or the cover body 20 ranges from 1.5 mm to 6 mm, so that the thickness of the box body 10 and / or the cover body 20 can be selected according to specific needs to meet different design requirements and usage scenarios.

[0076] This thickness range can ensure the strength and stability of the box body 10 and / or the cover body 20, and also ensure its lightness, so as to facilitate stable installation through the mounting member 50. During the production process, a suitable thickness can be selected according to specific design requirements and usage scenarios to achieve a better use effect. Optionally, the thickness of the box body 10 and / or the cover body 20 can be 3.5 mm. Under this thickness, the mounting member 50 has a better fixing effect on the control box body 100.

[0077] Further, the thickness of the mounting member 50 is in the range of 12 mm to 16 mm. It can be understood that the thickness of the first mounting member 51 and the second mounting member 52 are both in the range of 12 mm to 16 mm, so that the thickness of the mounting members 50 on both sides is greater than the thickness of the box body 10 and / or the cover body 20, thereby improving the connection strength. During the production process, the appropriate thickness can be selected according to the specific design requirements and usage scenarios to achieve a better fixing effect.

[0078] In one embodiment, the length dimension of the box body 10 is L1, and the length dimension of the mounting member 50 is L2. The range of L1 is 400 mm-600 mm, and the range of L2 is 30 mm-50 mm.

[0079] The range of the mounting member 50 in the length direction of the box body 10 and the length range of the box body 10 are limited, thereby controlling the setting ratio of the mounting member 50 relative to the box body 10, so that the box body 10 and the mounting member 50 can cooperate with each other to ensure the stability and reliability of the mounting member 50 after connection.

[0080] In this way, by reasonably controlling the size range of L1 and L2, the connection stability and reliability of the control box 100 in the first direction F1 can be ensured.

[0081] In addition, this size design can also be adjusted according to different usage requirements to meet the needs of different users. For example, if a larger installation space is required, the size of L1 and L2 can be appropriately increased; if a smaller volume is required, the size of L1 and L2 can be appropriately reduced.

[0082] It should be noted that during the design and manufacturing process, the dimensions of L1 and L2 need to be precisely controlled to ensure that they can fit each other.

[0083] In one embodiment, the size of the box body 10 in the second direction F2 is L3, the size of the mounting member 50 in the second direction F2 is L4, the range of L3 is 300 mm-500 mm, and the range of L4 is 80 mm-120 mm.

[0084] Similarly, the range of the mounting member 50 in the width direction of the box body 10 and the width range of the box body 10 are limited, thereby controlling the setting ratio of the mounting member 50 relative to the box body 10, so that the box body 10 and the mounting member 50 can cooperate with each other, ensuring the stability and reliability of the mounting member 50 after connection.

[0085] In this way, by properly controlling the size ranges of L1 and L2, the stability and reliability of the control box 100 in the second direction F2 can be ensured.

[0086] In addition, this size design can also be adjusted according to different usage requirements to meet the needs of different users. For example, if a larger installation space is required, the size of L3 and L4 can be appropriately increased; if a smaller volume is required, the size of L3 and L4 can be appropriately reduced.

[0087] In other embodiments, if the dimensions L1 and L3 of the box body 10 in the first direction F1 and the second direction F2 are set to other ranges, the corresponding dimensions L2 and L4 of the mounting member 50 can be obtained according to the corresponding proportions, thereby ensuring the fixing strength of the control box body 100 in all directions after the mounting member 50 is connected.

[0088] In one embodiment, the density of the electrical insulation material used in the control box 100 is in the range of 1000 kg / m³-1400 kg / m³.

[0089] Specifically, limiting the above density range means that the electrical insulation material has a relatively suitable density, which can provide better electrical insulation performance and strength while ensuring its lightness. When manufacturing the control box 100, using the electrical insulation material with a density within this range can ensure the stability and lightness of the control box 100, thereby ensuring the fixing strength.

[0090] It should be noted that the density of the electrical insulating material is related to its performance and quality. When the volume is constant, the greater the density, the greater the quality. Therefore, when using it, it is necessary to make an adaptive selection according to the load-bearing conditions of the mounting member 50. In addition, when selecting an electrical insulating material, it is also necessary to consider its other performance parameters, such as heat resistance, corrosion resistance, aging resistance, etc., to ensure its reliability and stability in practical applications.

[0091] Optionally, the density of the electrical insulation material used in the control box 100 is about 1200 kg / m³, that is, the density can be 1200 kg / m³, or 1200 kg / m³±a smaller deviation value kg / m³. The control box 100 formed with a density of about 1200 kg / m³ has better electrical insulation performance, strength and lightness. It can be understood that at this density, the specific material type of the electrical insulation material is not limited.

[0092] In one embodiment, the cover 20 is also provided by injection molding, which can provide better durability and stability, and can also improve production efficiency. Through injection molding, each part of the cover 20 can be manufactured at one time, avoiding problems caused by processes such as assembly and welding. In addition, injection molding can also provide better appearance quality and dimensional accuracy, making the cover 20 more beautiful and practical.

[0093] In one embodiment, the cover 20 and the box body 10 are movably connected. Specifically, the cover 20 can be directly and integrally connected to the box body 10 in a detachable manner, so that the cover 20 can be removed from the box body 10 as a whole to facilitate maintenance of the interior of the electric control space 30. One side of the cover 20 can also be rotatably connected to the box body 10. Specifically, refer to Figure 4 and Figures 6 to 8 A first rotating portion 15 is provided on one side of the box body 10, and the cover body 20 is rotatably connected to the box body 10 via the first rotating portion 15, so that the cover body 20 can be rotated to cover the opening 16 or open the opening 16 to meet different usage requirements.

[0094] Furthermore, the box body 10 is provided with a second rotating part 24 that is rotatably matched with the first rotating part 15. One of the two can be a protrusion and the other has a groove. The first rotating part 15 and the second rotating part 24 are plugged into each other and are rotatably connected around the plugging direction.

[0095] In one embodiment, see Figures 6 to 8 The cover body 20 has a mating portion 23, and the control box body 100 includes a locking member 40, which is provided on the box body 10 and can cooperate with the mating portion 23 to lock the cover body 20 and the box body 10, so that when the cover body 20 is rotated to cover the box body 10, the cover body 20 and the box body 10 are fixed by the cooperation of the locking member 40 and the mating portion 23.

[0096] Further, see Figure 4 , Figure 6 and Figure 8 The locking member 40 is located at a side of the box body 10 where the opening 16 is provided, and has a locking portion 41 protruding relative to the opening 16 . The locking portion 41 can at least partially engage with the matching portion 23 , thereby fixing the box body 10 and the cover body 20 .

[0097] It can be understood that when the opening 16 needs to be opened, it is only necessary to operate to separate the locking portion 41 from the matching portion 23. The specific locking method and unlocking method are not limited in this application.

[0098] In a specific embodiment, the mating portion 23 has a locking surface facing away from the box body 10, and the locking member 40 also includes an operating portion 42, which is rotatably connected to the box body 10, one end of the locking portion 41 is rotatably connected to the operating portion 42, and the other end forms a locking protrusion, which is used to cooperate with the locking surface in a limiting manner.

[0099] When the locking protrusion and the locking surface are in limited cooperation, the user can lift the side of the operating part 42 away from the locking part 41 to move it away from the box body 10. The operating part 42 rotates relative to the box body 10, and the locking part 41 is driven by the operating part 42 to rotate and displace, and the locking protrusion is disengaged from the locking surface, completing the unlocking.

[0100] Similarly, in the unlocked state, the user can press the side of the operating part 42 away from the locking part 41 to move it toward the side close to the box body 10. The operating part 42 rotates relative to the box body 10, and the locking part 41 is driven by the operating part 42 to rotate and displace, and the locking protrusion approaches and gradually abuts against the locking surface to complete the locking.

[0101] The control box 100 provided in the present application is a light-weight control box 100 formed by electrically insulating materials. The control box 100 formed by electrically insulating materials is light-weight. It only needs to set mounting parts 50 on opposite sides of the geometric center line FL of the control box 100, so that the control box 100 can be fixed by two fixed points on opposite sides of the geometric center line FL. The assembly is simple, firm and efficient.
