[0005] To solve the above problems, the present invention provides an electrical box structure, which includes:

[0006] A box body, components and connectors. The box body has an internal accommodation space, and the components and the connectors are arranged in the accommodation space; the box body further includes a first plate and a second plate that are perpendicular to each other. The first end of the component is fixedly installed on the first plate, and the second end of the component is fixedly installed on the connector and then fixed on the second plate through the connector.

[0007] In some embodiments, the second end of the component is located on the inner side of the box body relative to the first end of the component. The side of the first plate that is connected to the second plate is the first side. The second end of the component being located on the inner side of the box body relative to the first end of the component means that: the distance between the second end of the component and the first side is less than the distance between the first end of the component and the first side.

[0008] In some embodiments, it further includes a first box cover and a second box cover. The first box cover is detachably and fixedly connected to the first side of the box body; the second box cover is detachably and fixedly connected to the second side of the box body; any one of the first box cover and the second box cover can be disassembled to take out the components.

[0009] In some embodiments, the first box cover is disposed perpendicular to the second box cover; the first box cover is disposed opposite to the first plate; the second box cover is disposed opposite to the second plate.

[0010] In some embodiments, a first hem is provided on the box body at the position where the box body is connected to the first box cover; and / or, a second hem is provided on the box body at the position where the box body is connected to the second box cover.

[0011] In some embodiments, the first box cover and the box body are detachably and fixedly connected by a fourth threaded fastener; the second box cover and the box body are detachably and fixedly connected by a fifth threaded fastener.

[0017] The connecting member is an L-shaped sheet metal part.

[0018] The present invention also provides an air conditioner, which includes the electrical box structure described in any one of the previous items.

[0019] The electrical box structure and the air conditioner provided by the present invention have the following beneficial effects:

[0020] 1. By setting the structure of the connecting piece inside the box body, the present invention effectively fixes the second end of the component to the connecting piece first, then fixes the connecting piece to the second board, and finally fixes the first end of the component to the first board. That is, through the structure of the connecting piece, the two ends of the component are effectively fixed to the perpendicular first board and second board inside the box body respectively, and the second end is located inside the box body. When it is necessary to disassemble the component for maintenance or when it is necessary to maintain the inside of the electrical box, it is only necessary to open the side box cover opposite to the first board or only open the side box cover opposite to the second board. When opening the side box cover opposite to the first board, the first end of the component is disassembled from the first board along the direction perpendicular to the first board, and at the same time, the second end of the component is disassembled from the connecting piece, completing the disassembly process of the component. When opening the side box cover opposite to the second board, the connecting piece is disassembled from the second board along the direction perpendicular to the second board, and at the same time, the first end of the component located outside is disassembled from the first board, completing the disassembly process of the component. Therefore, the present invention fixes the component that is difficult to operate in a certain direction on a connecting piece, and the connecting piece is fixed on the electrical box. The fixing direction of the connecting piece is perpendicular to the fixing direction of the component, so that the component can be disassembled in two directions. It is possible to perform maintenance from two sides; the effect of being able to take out the component from both sides is achieved; the problem of the need for multi-sided maintenance or the inability to disassemble due to the inconsistent assembly direction and maintenance direction of the component is solved.

[0021] 2. When there is a need for multi-sided maintenance or the assembly direction and maintenance direction of the component are inconsistent, for the components that can be repaired and disassembled on both sides, their placement method remains unchanged. For the components that cannot be disassembled on a certain side, fixing them through a connecting piece (preferably an L-shaped sheet metal part) can achieve their maintainability on both sides.

[0022] 3. Since two sides need to be left empty for maintenance, how to achieve a certain mechanical strength for the remaining 4 sides, especially the strength of the two sides connected to both maintenance sides. The present invention increases the hem on each side, which can not only increase the strength but also play a role in waterproofing. For the strength of the two sides connected to both maintenance sides, not only hem is needed, but also the two sides need to be strengthened by fixing with bolts of the electrical box cover.

Specific embodiments

[0032] As Figures 1-7 shown, the present invention provides an electrical box structure, which includes:

[0033] A box body 1, a component 4 (preferably a main board) and a connecting piece 5, the box body 1 has an internal accommodation space, and the component 4 and the connecting piece 5 are arranged in the accommodation space; the box body 1 further includes a first plate 11 and a second plate 12 that are perpendicular to each other, the first end 41 of the component 4 is fixedly installed on the first plate 11, and the second end 42 of the component 4 is fixedly installed on the connecting piece 5 and then fixed to the second plate 12 through the connecting piece 5.

[0034] By setting the structure of the connecting piece inside the box body, the present invention effectively fixes the second end of the component to the connecting piece first, then fixes and connects the connecting piece to the second board, and finally fixes the first end of the component to the first board. That is, through the structure of the connecting piece, the two ends of the component are effectively fixed to the perpendicular first board and second board inside the box body respectively, and the second end is located inside the box body. When it is necessary to disassemble the component for maintenance or to maintain the inside of the electrical box, it is only necessary to open the side box cover opposite to the first board or only open the side box cover opposite to the second board. When opening the side box cover opposite to the first board, the first end of the component is disassembled from the first board along the direction perpendicular to the first board, and at the same time, the second end of the component is disassembled from the connecting piece to complete the disassembly process of the component. When opening the side box cover opposite to the second board, the connecting piece is disassembled from the second board along the direction perpendicular to the second board, and at the same time, the first end of the component located outside is disassembled from the first board to complete the disassembly process of the component. Therefore, the present invention fixes the component that is difficult to operate in a certain direction on a connecting piece, and the connecting piece is fixed on the electrical box. The fixing direction of the connecting piece is perpendicular to the fixing direction of the component, so that the component can be disassembled in two directions. It is possible to perform maintenance from two sides; achieve the effect that the component can be taken out from both sides; solve the problem that the need for multi-sided maintenance cannot be met or the component cannot be disassembled due to the inconsistent assembly direction and maintenance direction of the component.

[0035] When the existing single-sided maintenance cannot meet the requirements, the present invention provides an electrical box structure with two-sided maintenance: it can: 1. Realize maintenance from two sides; 2. Realize that the component can be taken out from both sides; 3. Ensure the structural strength of the electrical box.

[0036] In some special cases of the existing electrical box structure, the maintenance of the electrical box not only requires maintenance from the front, but also requires maintenance from the side. Ordinary electrical boxes can only be maintained from the front. When the front cannot meet the maintenance conditions due to the installation environment, this electrical box has no maintainability. To avoid such things from happening, two-sided maintainability is very necessary. The electrical box of the present invention has two maintenance openings and is equipped with 2 electrical box covers to ensure the requirements of two-sided maintainability.

[0037] For both sides to be maintainable, it is necessary to be able to take out the components inside from both sides. Therefore, the placement method of the components is also extremely particular. The present invention cleverly fixes the component that is difficult to operate in a certain direction on a sheet metal, and the sheet metal is fixed on the electrical box. The fixing direction of the sheet metal is perpendicular to the fixing direction of the component, so that the component can be disassembled in two directions.

[0038] In some embodiments, the second end 42 of the component 4 is located on the inner side of the box body 1 relative to the first end 41 of the component 4. The side of the first plate 11 that is connected to the second plate 12 is the first side 111. The second end 42 of the component 4 being located on the inner side of the box body 1 relative to the first end 41 of the component 4 means that: and the distance between the second end 42 of the component 4 and the first side 111 is less than the distance between the first end 41 and the first side 111. This is the preferred setting position of the connecting member of the present invention, that is, the connecting member is arranged on the inner side close to the electrical box. That is, the determination method is that the distance between the second end of the component and the first side of the first plate is less than the distance between the first end and the first side. The second side 112 of the first plate is opposite to the first side 111. That is, the first end of the component without the connecting member is close to the outside, and the second end of the component with the connecting member is close to the inner side of the box body. This can more effectively and conveniently remove the component from the inside of the box body in both directions (if the end with the connecting member is close to the outside, it will cause obstruction and is not conducive to removing the inner end of the component).

[0039] In some embodiments, it further includes a first box cover 2 and a second box cover 3. The first box cover 2 is detachably and fixedly connected to the first side of the box body 1; the second box cover 3 is detachably and fixedly connected to the second side of the box body 1; by removing either the first box cover 2 or the second box cover 3, the component 4 can be removed. This is a further preferred structural form of the present invention. Through the first and second box covers, the empty two sides of the box body can be effectively connected and the box body can be covered to form an integral and complete enclosed electrical box structure. The first box cover and the second box cover are perpendicular to each other. Removing either the first box cover or the second box cover can remove the component from its internal space, as Figures 6-7 shown.

[0040] In some embodiments, the first box cover 2 and the second box cover 3 are perpendicularly arranged; the first box cover 2 is arranged opposite to the first plate 11; the second box cover 3 is arranged opposite to the second plate 12. This is the preferred structural form of the first and second box covers of the present invention, that is, the first box cover covers one side of the box body, and the second box cover covers the side adjacent to the first box cover.

[0041] In some embodiments, a first hem 13 is provided on the box body 1 at the position where the box body 1 is connected to the first box cover 2; and / or, a second hem 14 is provided on the box body 1 at the position where the box body 1 is connected to the second box cover 3. The present invention also provides a first hem connected to the first box cover on the box body and a second hem connected to the second box cover, which can not only increase the strength but also play a role in waterproofing. For the strength of the two surfaces connected to the two maintenance surfaces, not only the hems are required, but also the two surfaces need to be strengthened by fixing with bolts of the electrical box cover.

[0042] In some embodiments, the first box cover 2 and the first hem 13 are detachably and fixedly connected by a fourth threaded fastener 64; the second box cover 3 and the second hem 14 are detachably and fixedly connected by a fifth threaded fastener 65. The present invention can also effectively fix and detachably connect the first box cover and the first hem through the fourth threaded fastener, and can also effectively fix and detachably connect the second box cover and the second hem through the fifth threaded fastener.

[0043] In some embodiments, the connecting member 5 includes a first mounting plate 51 and a second mounting plate 52, the first mounting plate 51 and the second mounting plate 52 are connected to each other and are perpendicular to each other; the second end 42 of the component 4 is fixedly mounted on the first mounting plate 51 and is fixedly mounted on the second plate 12 through the second mounting plate 52. This is a further preferred structural form of the connecting member of the present invention. Through the structure of the perpendicular first and second mounting plates, the first mounting plate can be used to connect with the component, and the second mounting plate can be used to connect with the second plate of the box body. That is, finally, the first end of the component is mounted on the first plate, and the second end is connected to the second plate through the connecting member, so that the component is mounted on two perpendicular plates, facilitating the effect of detaching the component from both sides.

[0044] In some embodiments, the second mounting plate 52 is disposed in a fitting manner with the second plate 12; and / or, the first mounting plate 51 is parallel or in a fitting manner with the first plate 11. This is a further preferred structural form of the first mounting plate and the second mounting plate of the present invention. The second mounting plate needs to be fixed to the second plate. Therefore, the second mounting plate can be effectively fixedly connected to the second plate by being disposed in a fitting manner with the second plate. The first mounting plate may or may not be in a fitting manner with the first plate. However, since the first mounting plate is perpendicular to the second mounting plate and the first plate is perpendicular to the second plate, the first mounting plate is parallel to the first plate.

[0045] In some embodiments, the first end 41 of the component 4 is fixed to the first plate 11 by a first threaded fastener 61; and / or,

[0046] The second end 42 of the component 4 is fixed to the first mounting plate 51 of the connecting member 5 by a second threaded fastener (not shown); and / or,

[0047] The second mounting plate 52 is fixedly mounted on the second plate 12 by a third threaded fastener 63; and / or,

[0048] The connecting member 5 is an L-shaped sheet metal part.

[0049] This is a further preferred structural form of the present invention. It can firmly and removably fix the first end of the component to the first plate through the first threaded fastener, can firmly and removably fix the second end of the component to the first mounting plate of the connecting member through the second threaded fastener, and can firmly and removably fix the second mounting plate of the connecting member to the second plate through the third threaded fastener; the L-shaped sheet metal part becomes the preferred structural form of the connecting member, and can effectively form a first mounting plate and a second mounting plate that are perpendicular to each other.

[0050] The present invention also provides an air conditioner, which includes the electrical box structure described in any one of the preceding items.

[0051] The present invention is designed for a special air conditioner. Due to the limitations of the overall space and installation method, the assembly port and the maintenance port of the components in the electrical box are inconsistent, so this structure needs to have two non-closed sides. The electrical box structure can achieve two-sided maintenance, and the components can also be taken out from both sides. Since it is a special air conditioner with high requirements for structural strength, the present invention realizes qualified high-strength vibration by adding flanges and fixing the electrical cover.

[0052] Beneficial effects: Solve the problem of maintaining the electrical box with inconsistent assembly ports and maintenance ports, so that all components can be smoothly taken out from both sides, ensuring that when one side cannot be maintained, the other side can still be maintained. On the other hand, aiming at the disadvantage of weak strength for two-sided maintenance, the present invention makes the strength meet the national standard requirements through the connection and fixation of the flange and the electrical box.

[0053] Detailed description of the local structure:

[0054] 1. The electrical box structure includes a box body 1, a first box cover 2 and a second box cover 3. Due to the special requirements of the model, it is necessary to open a maintenance port on the narrow side. The direction of the first box cover 2 is the assembly port, and the second box cover 3 is the maintenance port.

[0055] 2. As Figure 2In the displayed arrangement of components, all other components can be taken out, but component 4 (preferably the main board) cannot be directly taken out from this maintenance surface. Therefore, in the present invention, an L-shaped sheet metal (connector 5) is adopted. First, component 4 is fixed on the L-shaped sheet metal, and then the L-shaped sheet metal is fixed on the electrical box. By removing the fixing bolts of the L-shaped sheet metal and the electrical box, the main board can be repaired.

[0056] 3. Figures 2-3 What is shown is the arrangement of components on the assembly surface, and the components can be disassembled and assembled in sequence. Figure 5 This is the structure of the L-shaped sheet metal.

[0057] 4. In Figure 6 and Figure 7 As shown, the electrical box strengthens the structural strength by adding flanges at both the maintenance opening and the assembly opening, but the strength of the upper and lower surfaces of the electrical box is still insufficient. In the present invention, the upper and lower surfaces are connected by bolts and the electrical box cover to achieve the predetermined structural strength.

[0058] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention. The above is only the preferred implementation manner of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and modifications can still be made, and these improvements and modifications should also be regarded as within the protection scope of the present invention.
