There are a plurality of first support members 30, and the plurality of first support members 30 are disposed on the mounting plate 20, and the first support members 30 are used to support the mounting frame 200. The cover plate 40 is disposed in the bottom shell 10, and the cover plate 40 is located on a side of the mounting plate 20 close to the opening of the bottom shell 10, and the cover plate 40 can cover the mounting plate 20.

[0068] The box cover 50 is movably connected to the bottom shell 10, and the box cover 50 has a closed state and an open state. When the box cover 50 is in the closed state, the box cover 50 blocks the opening of the bottom shell 10 to shield and protect the internal mechanism of the bottom shell 10. When the box cover 50 is in the open state, the staff can inspect, repair, connect wires, etc. to the internal mechanism of the bottom shell 10.

[0069] See also Figure 3 and Figure 4 In some embodiments, the mounting plate 20 is provided with a first mounting area 21, and the first mounting area 21 has a plurality of first mounting positions 211. The plurality of first mounting positions 211 are spaced apart along a first direction (i.e., the X-axis direction shown in the figure), and the first direction corresponds to the length direction of the mounting frame 200.

[0070] The first support member 30 has a first end 31 and a second end 32, wherein the first end 31 is used to be detachably connected to the first mounting position 211, and the second end 32 is used to be detachably connected to the mounting frame 200. When at least one first mounting position 211 is connected to the first support member 30, the first support member 30 connected to the first mounting position 211 can support the mounting frame 200.

[0071] Among them, the number of first support members 30 can be configured according to the length of the mounting frame 200 that needs to be fixed, and the first mounting area 21 can be configured so that all first mounting positions 211 are connected to the first support members 30, or it can be configured so that some of the first mounting positions 211 are connected to the first support members 30.

[0072] See also Figure 4 , Figure 5 and Figure 6 For ease of understanding, the following takes 4 as an example of the number of the first mounting positions 211 to illustrate different application scenarios of the first mounting bracket 201 and the second mounting bracket 202.

[0073] When the first mounting frame 201 needs to be fixed, the number of the first support members 30 may be four, and the four first support members 30 are respectively installed in the four first installation positions 211 to meet the installation requirements for a large number of circuit breakers.

[0074] When the second mounting frame 202 needs to be fixed, the number of first support members 30 can be 3, and three first support members 30 are respectively installed in three first mounting positions 211, leaving one first mounting position 211 empty to meet the installation requirements for a smaller number of circuit breakers.

[0075] It can be understood that by installing a corresponding number of first support members 30 on multiple first mounting positions 211, it is possible to support the fixation of mounting frames 200 of different lengths, meet diverse installation requirements, and be suitable for installing circuit breakers of different numbers or specifications. In this way, the same mounting plate 20 structure is used in combination with multiple first support members 30, which can be used in different application scenarios. When installing different mounting frames 200 and circuit breakers, there is no need to make significant changes to the overall structure of the box. Only the number and distribution of the first support members 30 need to be adjusted. It is widely used and suitable for various types of inverters and energy storage products. At the same time, the standardization of the structure of the distribution box 100 of the present application is higher, which reduces the production cycle of the structural design, thereby improving production efficiency and reducing production costs.

[0076] See also Figure 2 and Figure 7 In some embodiments, the bottom shell 10 is in a rectangular shape as a whole, and is formed by processing an aluminum plate, which has better heat dissipation performance. The surface of the bottom shell 10 is sprayed with neutral salt spray resistance and sprayed with anti-bake, and has the characteristics of corrosion resistance, high strength and high temperature resistance.

[0077] In some embodiments, a copper busbar 12 is disposed on the bottom wall of the bottom shell 10 , and the electronic components inside the bottom shell 10 can be grounded through the copper busbar 12 , which makes grounding convenient and safer.

[0078] In some embodiments, a plurality of support sheets 13 are disposed on the inner side of the bottom shell 10, and the support sheets 13 are used to be detachably connected to the cover plate 40 to support and fix the cover plate 40. There is a distance between the support sheets 13 and the bottom wall of the bottom shell 10, so that a certain space is left between the cover plate 40 and the bottom wall of the bottom shell 10 for other structures such as the mounting plate 20. There is a spacing between the support sheets 13 and the opening of the bottom shell 10 to form a positioning space, which has a positioning function for the cover plate 40.

[0079] Exemplarily, the number of support sheets 13 is 4, and the four support sheets 13 are welded and fixed at the four corners of the bottom shell 10. In other examples, the number and distribution of support sheets 13 can also be configured according to the shape of the bottom shell 10 and the requirements for support strength, which is not limited in this application.

Among them, the number and specifications of the waterproof plugs 14 can be configured according to the electronic devices that need to be wired, and this application does not limit this.

[0081] See also Figure 8In some embodiments, a hanging bracket 15 is provided on the back of the bottom shell 10, and the hanging bracket 15 is bolted and fixed to the bottom shell 10. The hanging bracket 15 is used to be hung and fixed to an external fixed object, and the fixed object can be a wall, a column, etc. In this way, when the distribution box 100 is in use, the distribution box 100 can be hung on a fixed object through the hanging bracket 15, which is convenient for operators to open the distribution box 100 for operation, and the maintainability is high. In the example of this embodiment, when the distribution box 100 is hung on a fixed object, the waterproof plug 14 is located at the lower end of the bottom shell 10.

[0082] See also Figure 7 and Fig. 9 In some embodiments, the box cover 50 is a flip-type movable structure. One side of the box cover 50 is rotatably connected to the bottom shell 10, and the other side of the box cover 50 is detachably connected to the bottom shell 10. In the example of this embodiment, when the distribution box 100 is hung on a fixed object, the rotation axis of the box cover 50 is set in a vertical direction, and the operator can flip the box cover 50 to open and close, which is convenient for the operator to operate.

[0083] For example, one side of the box cover 50 is rotatably connected to the bottom shell 10 through a hinge structure, and the other side of the box cover 50 is detachably connected to the bottom shell 10 through a buckle structure 16. When the distribution box 100 needs to be opened, the buckle structure 16 can be unlocked to flip the box cover 50 from the opening of the bottom shell 10 to open it, so as to switch it to an open state; when the distribution box 100 needs to be closed, the box cover 50 can be flipped and closed to the opening of the bottom shell 10 to switch it to a closed state, and the buckle structure 16 can be locked.

[0084] In some embodiments, a sealing strip 51 is provided between the box cover 50 and the bottom shell 10. When the box cover 50 is in a closed state, the box cover 50 and the bottom shell 10 cooperate to squeeze the sealing strip 51, so that the sealing strip 51 seals the gap between the box cover 50 and the bottom shell 10, which can prevent moisture, particles, etc. in the external environment from affecting the internal structure of the bottom shell 10, and meet the requirements of waterproof sealing.

[0085] See also Figure 3 and Figure 4 In some embodiments, the shape of the mounting plate 20 matches the shape of the bottom shell 10, and the overall size of the mounting plate 20 is smaller than the area of ​​the opening of the bottom shell 10, so that the mounting plate 20 can enter and exit the bottom shell 10 through the opening of the bottom shell 10. The mounting plate 20 and the bottom shell 10 are connected and fixed by a pressure riveting stud structure.

[0086] In some embodiments, the first mounting area 21 is located at one end of the mounting plate 20 in the second direction (i.e., the Y-axis direction shown in the figure), and the second direction and the first direction have an angle. The distribution position of the first mounting area 21 allows space to be left at the other end of the mounting plate 20 for other structures to be arranged, thereby improving space utilization.

[0087] In some embodiments, the distribution box 100 also includes multiple second support members 60, the structure of the second support member 60 is consistent with the structure of the first support member 30, one end of the second support member 60 can also be detachably connected to the mounting plate 20, and the other end of the second support member 60 can also be detachably connected to the mounting frame 200.

[0088] In some embodiments, the mounting plate 20 is further provided with a second mounting area 22, which is spaced apart from the first mounting area 21 in the second direction. Exemplarily, the second mounting area 22 is located at one end of the mounting plate 20 away from the first mounting area 21.

[0089] The second installation area 22 has a plurality of second installation positions 221, and the plurality of second installation positions 221 are spaced apart along the first direction. The second installation positions 221 are used to be detachably connected to the second support member 60. In the case where at least one second installation position 221 is connected to the second support member 60, the second support member 60 connected to the second installation position 221 can support the mounting frame 200. It can be understood that both the first installation area 21 and the second installation area 22 can fix the mounting frame 200, so that multiple electronic devices can be installed using multiple mounting frames 200, thereby improving the integration degree of the wiring box.

[0090] See also Figure 4 and Fig.10 In the example of this embodiment, the first mounting area 21 can be installed with a first mounting rack 201, and the first mounting rack 201 is used to install multiple circuit breakers. The second mounting area 22 can be installed with a third mounting rack 203, and the third mounting rack 203 is used for electronic instruments and status indicator lights.

[0091] In some embodiments, the mounting plate 20 is further provided with a third mounting area 23, the third mounting area 23 and the second mounting area 22 are spaced apart in the first direction, and the sum of the lengths of the third mounting area 23 and the second mounting area 22 in the first direction corresponds to the length of the first mounting area 21 in the first direction. The third mounting area 23 is provided for detachable connection of electronic devices. Exemplarily, the third mounting area 23 is used to install an ATS switch, and the ATS switch is directly fixed to the mounting plate 20 by screws.

[0092] It can be understood that the first installation area 21, the second installation area 22 and the third installation area 23 can be used to install electronic devices with different functions or different wiring methods to meet the installation requirements and space allocation of different electronic devices, making it convenient for operators to organize and summarize the various electronic devices inside the power distribution box 100.

[0093] In some embodiments, a plurality of convex bumps 24 are disposed in the middle of the mounting plate 20, and the convex bumps 24 are disposed on the mounting plate 20 in a direction away from the bottom wall of the bottom shell 10, and a gap is formed between the convex bumps 24 and the surface of the mounting plate 20. The convex bumps 24 can be used with cable ties to fix the wires inside the bottom shell 10, so as to facilitate the arrangement of the wiring.

[0094] See also Figure 3 and Fig.10 In some embodiments, the first support member 30 is perpendicular to the mounting plate 20 as a whole, and the first support member 30 is extended along a third direction (such as the third axis direction shown in the figure). The first support member 30 is close to the mounting plate 20 to form a first end 31, and the first support member 30 is far from the mounting plate 20 to form a second end 32.

[0095] Exemplarily, the first end 31 and the first mounting position 211 can be detachably connected by bolting through a rivet screw structure; in other examples, the first end 31 and the first mounting position 211 can also be detachably connected by means of a snap connection, an interference fit, etc. Exemplarily, the second end 32 and the mounting frame 200 can be detachably connected by bolting through a set screw. In other examples, the second end 32 and the mounting frame 200 can also be detachably connected by means of a snap connection, an interference fit, etc.

[0096] In some embodiments, a first fixing block 33 is disposed on the side of the first end 31, the first fixing block 33 is parallel to the mounting plate 20, and the first fixing block 33 is used to abut against the mounting plate 20 and be detachably connected to the first mounting position 211. For example, a through hole is disposed in the middle of the first fixing block 33, and a corresponding first mounting hole is disposed in the first mounting position 211, and the rivet screw structure is screwed with the first mounting hole through the through hole.

[0097] It can be understood that when the first support member 30 is fixed to the first installation position 211 , the first support member 30 cooperates with the installation plate 20 through the first fixing block 33 to increase the contact area and improve the installation stability of the first support member 30 .

[0098] See also Figure 3 and Figure 5 In some embodiments, there are multiple first fixing blocks 33, and the multiple first fixing blocks 33 are distributed on opposite sides of the first end 31, and the distribution direction of the multiple first fixing blocks 33 located on the same first support member 30 has an angle with the first direction. Exemplarily, each first end 31 is provided with two first fixing blocks 33, and the two first fixing blocks 33 are located on opposite sides of the first end 31 to form a group. For ease of understanding, the distribution direction of the same group of first fixing blocks 33 in this embodiment is indicated by the extension direction of the dotted line A in the figure.

[0099] In this way, each group of first fixing blocks 33 is distributed on both sides of the mounting frame 200 on the projection of the mounting plate 20, thereby increasing the supporting stability of the first support member 30 on the mounting frame 200 and reducing the risk of the first support member 30 tipping over when placed horizontally.

[0100] Furthermore, there is an angle between the distribution direction of the first fixing blocks 33 located on both sides of the same first support member 30 and the distribution direction of the first fixing blocks 33 located on both sides of another adjacent first support member 30 .

[0101] In this way, there is an angle between the distribution directions of two adjacent groups of first fixed blocks 33, so that multiple groups of first fixed blocks 33 form a V-shaped distribution on the mounting plate 20, expanding the supporting area formed by multiple groups of first fixed blocks 33 on the mounting plate 20, and further increasing the supporting stability of the first support member 30 on the mounting frame 200.

[0102] In some embodiments, the second end 32 of the first support member 30 is provided with a first mounting block 34, and a connection hole is provided in the middle of the first mounting block 34, and the connection hole is used to cooperate with the fastening screw to bolt with the mounting frame 200. In this way, when the first support member 30 is connected between the mounting frame 200 and the mounting plate 20, a triangular support structure is formed between the first mounting block 34 and the first fixing block 33 of the first support member 30 to improve the support strength.

[0103] In some embodiments, the first support member 30 is integrally formed, wherein the main body of the first support member 30 can be formed by a bending process, and the main body of the first support member 30 forms a hollow structure, and the first mounting block 34 and the first fixing block 33 are distributed at both ends of the main body of the first support member 30 and formed by a bending process. In this way, the assembly steps of the first support member 30 can be reduced, the production cost can be reduced, and the overall weight of the first support member 30 can be reduced.

[0104] See also Figure 4 and Fig.10 In some embodiments, corresponding to the structure of the first support member 30, the second support member 60 is provided with a second mounting block and a plurality of second fixing blocks 61. The second mounting position 221 is provided with a second mounting hole corresponding to the second fixing block 61, and the second support member 60 is screwed to the second mounting position 221 through a rivet screw structure.

[0105] In some embodiments, the plurality of second fixing blocks 61 located on the same second support member 60 are distributed along the second direction. In this way, the plurality of second fixing blocks 61 are distributed on both sides of the projection of the mounting frame 200 on the mounting plate 20, thereby increasing the support stability of the second support member 60 on the mounting frame 200, and reducing the distribution length of the plurality of second fixing blocks 61 in the first direction, thereby reducing the space occupied by the second support member 60 in the first direction, and leaving enough space for the third mounting area 23 to be set.

[0106] In some embodiments, the shape of the cover plate 40 is configured to correspond to the shape of the opening of the bottom shell 10 , so that the cover plate 40 can be adaptively received in the opening of the bottom shell 10 .

[0107] See also Figure 2 and Fig.10 In some embodiments, the cover plate 40 is provided with a first communication port 41, and the position of the first communication port 41 corresponds to the distribution position of the plurality of first support members 30 connected to the plurality of first mounting positions 211. In this way, the mounting frame 200 (i.e., the first mounting frame 201) mounted on the first support member 30 can be exposed to the cover plate 40 through the first communication port 41.

[0108] The cover plate 40 is further provided with a second communication opening 42, the position of which corresponds to the distribution position of the plurality of second support members 60 connected to the plurality of second mounting positions 221. Thus, the mounting frame 200 (i.e., the third mounting frame 203) mounted on the second support member 60 can be exposed to the cover plate 40 through the second communication opening 42.

[0109] It is worth noting that the positions and sizes of the first communication opening 41 and the second communication opening 42 can be adjusted according to the length and width of the corresponding mounting frame 200 , and the present application does not impose any limitation on this.

[0110] See also Figure 2 and Figure 7 In some embodiments, the cover plate 40 is provided with a plurality of locking holes 43, and the positions of the plurality of locking holes 43 correspond to the positions of the plurality of support sheets 13. The cover plate 40 is screwed and fixed to the corresponding support sheets 13 through the plurality of locking holes 43, so that the cover plate 40 is fixed in the bottom shell 10.

[0111] It can be understood that when the cover plate 40 is fixed to the support sheet 13, the cover plate 40 effectively isolates the wires inside the bottom case 10, and only some electronic components are exposed to the cover plate 40 through the first communication port 41 or the second communication port 42. When the cover plate 40 is removed from the support sheet 13, the staff can inspect, repair, and connect the internal mechanism of the bottom case 10.

[0112] In some embodiments, a handle 44 is provided on one side of the cover plate 40 that is away from the bottom wall of the bottom shell 10. Exemplarily, the cover plate 40 is integrally formed, and the handle 44 is formed by bending and turning up one end of the cover plate 40. When the distribution box 100 is hung on a fixed object, the handle 44 is located at the lower end of the cover plate 40.

[0113] It is understandable that when the cover 40 needs to be removed from the support sheet 13, the staff can apply force to the cover 40 through the handle 44 to flip open the movable cover 40, which is convenient for the staff to apply force and reduces the risk of the staff touching the internal electronic components.

[0114] It is obvious to those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and that the present application can be implemented in other specific forms without departing from the spirit or basic features of the present application. Therefore, no matter from which point of view, the above embodiments of the present application should be regarded as exemplary and non-restrictive, and the scope of the present application is defined by the attached claims rather than the above description, and therefore it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present application.
