It should be understood that those skilled in the art will recognize that this application can be made without using these specific details. In other instances, well-known structures and processes are not described in detail to avoid obscuring the description of this application with unnecessary detail. Therefore, this application is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0028] like Figures 1 to 4 As shown, in one aspect, this application provides an electrical control box 1, which includes a first electrical control board 10 and a second electrical control board 20, which can improve assembly efficiency, maintenance and disassembly convenience and structural stability.

[0029] The first control board 10 has a first folded edge 11 and a first hook-on portion 12. The first folded edge 11 is bent and formed on one side edge of the first control board 10, and the first hook-on portion 12 is disposed on the first folded edge 11. The second control board 20 is used to assemble with the first control board 10 to form an electrical control box 1, and has a second hook-on portion 22, which is adapted to hook onto the first hook-on portion 12.

[0030] The first folded edge 11 abuts against the second electronic control board 20, and the first hook part 12 and the second hook part 22 are hooked together along the first direction to connect and fix the first electronic control board 10 and the second electronic control board 20. Based on the hooking relationship, one of the first electronic control board 10 and the second electronic control board 20 will be reliably hooked onto the other under its own weight.

[0031] Compared with related technologies, the electrical control box 1 provided in this application embodiment uses the first hook part 12 and the second hook part 22 for hooking. Based on the hooking relationship, one of the first electrical control board 10 and the second electrical control board 20 is reliably hooked onto the other under its own weight, which effectively reduces the number of fasteners and installation steps required. The structure is relatively simple and easy to assemble, which can improve assembly efficiency, maintenance and disassembly convenience and structural stability.

[0032] The connection structure of the first connecting part 12 and the second connecting part 22 can be determined according to actual needs, and the embodiments of this application do not limit this. Figure 2 and Figure 3 As shown, in some embodiments, the first hook portion 12 can be a hook, and the second hook portion 22 can be a hook hole. Here, the first hook portion 12 can have a snap-fit ​​portion 121 and a limiting portion 122. The snap-fit ​​portion 121 connects the limiting portion 122 and the first folded edge 11 along a second direction. The outer diameter of the limiting portion 122 is larger than the outer diameter of the snap-fit ​​portion 121. The width of the snap-fit ​​portion 121 gradually increases along a first direction, giving the snap-fit ​​portion 121 a structure that gradually expands from top to bottom, such as a cone shape. The second direction is perpendicular to or inclined to the first direction. When the first hook portion 12 and the second hook portion 22 are installed, the limiting portion 122 can pass through the second hook portion 22 along the second direction. The snap-fit ​​portion 121 is located inside the second hook portion 22 and slides and snaps against the end of the second hook portion 22 along the first direction, so that the first hook portion 12 and the second hook portion 22 are hooked together. After the first coupling part 12 and the second coupling part 22 are coupled, the limiting part 122 can restrict the locking part 121 from disengaging from the second coupling part 22, and reliably engage with the second coupling part 22 by utilizing the gradually expanding structure of the locking part 121, thus ensuring the reliability of the coupling of the first coupling part 12 and the second coupling part 22.

[0033] In some examples, the second hook-on portion 22 may have a snap-fit ​​hole area 221 and a plug-in hole area 222 that are sequentially connected along a first direction. The width of the snap-fit ​​hole area 221 gradually increases along the first direction, giving the snap-fit ​​hole area 221 a tapered hole structure that gradually expands from top to bottom. When the first hook-on portion 12 and the second hook-on portion 22 are installed, the limiting portion 122 can pass through the plug-in hole area 222 to the second hook-on portion 22, and the snap-fit ​​portion 121 can be inserted into the plug-in hole area 222 and slide and lock into the snap-fit ​​hole area 221 along the first direction, so that the first hook-on portion 12 and the second hook-on portion 22 are hooked together. After the first connecting part 12 and the second connecting part 22 are connected, the gradually expanding structure of the snap-fit ​​part 121 and the gradually expanding structure of the second connecting part 22 can be used to reliably snap them together, increasing the contact area between the snap-fit ​​part 121 and the second connecting part 22, and ensuring the reliability of the first connecting part 12 and the second connecting part 22 after connection.

[0034] like Figure 4As shown, in some embodiments, the first hook-up portion 12 can be a protruding rail portion formed on the first folded edge 11, and the second hook-up portion 22 can be a slot portion adapted to be inserted into the protruding rail portion. Here, the protruding rail portion and the slot portion can extend along a first direction, and the protruding rail portion can be inserted into the slot portion along the first direction. In this way, on the one hand, the slot portion can better accommodate the protruding rail portion from all sides, increasing the hook-up reliability between the first hook-up portion 12 and the second hook-up portion 22; on the other hand, the slot portion can guide the protruding rail portion, making the hook-up of the first hook-up portion 12 and the second hook-up portion 22 smoother.

[0035] The types of the aforementioned convex rail portion and slot portion can be determined according to actual needs, and this application embodiment does not limit this. In some examples, the first hook portion 12 can be a dovetail rail or a T-shaped rail, and the second hook portion 22 can be a dovetail groove or a T-shaped groove.

[0036] like Figures 1 to 3 As shown, in some embodiments, one of the first folded edge 11 and the second electronic control board 20 may have a through hole 23, and the other may have a fastening hole 13. A fastener (not shown) passes through the through hole 23 and is fastened to the fastening hole 13 to lock the first electronic control board 10 and the second electronic control board 20. In some examples, the first folded edge 11 may have a through hole 23, and the second electronic control board 20 may have a fastening hole 13. In other examples, the first folded edge 11 may have a fastening hole 13, and the second electronic control board 20 may have a through hole 23. The number of fastening holes 13 may be small, for example, one or two; this application embodiment does not limit this. The cooperation of the fastener and the fastening hole 13 can further increase the connection stability of the first electronic control board 10 and the second electronic control board 20.

[0037] The type of fastening hole 13 and the type of fastener can be determined according to actual needs, and this application embodiment does not limit this. In some examples, the fastening hole 13 can be a threaded hole, and the fastener can be a bolt. In other examples, the fastening hole 13 can be a pin hole, and the fastener can be a pin.

[0038] In some embodiments, the second control board 20 may have a second folded edge 21, which may be formed on one side edge of the second control board 20. A second mounting portion 22 may be disposed on the second folded edge 21, with the first folded edge 11 and the second folded edge 21 abutting against each other. By providing the first folded edge 11 and the second folded edge 21, the first control board 10 and the second control board 20 can be tightly connected, and interference with the installation of electronic components on the first control board 10 and the second control board 20 can be avoided.

[0039] The number of first connecting parts 12 and second connecting parts 22 can be determined according to actual needs, and can be one or more, which is not limited in this embodiment. In some embodiments, the first folded edge 11 may be provided with multiple first connecting parts 12, and the second electronic control board 20 may be provided with multiple second connecting parts 22. The number of multiple first connecting parts 12 and multiple second connecting parts 22 is equal, and they are connected one-to-one. In this way, the first electronic control board 10 and the second electronic control board 20 can be connected through multiple sets of first connecting parts 12 and second connecting parts 22, so that multiple connection relationships are formed between the first electronic control board 10 and the second electronic control board 20, further increasing the connection stability of the first electronic control board 10 and the second electronic control board 20.

[0040] The distribution of the plurality of first connecting parts 12 can be determined according to actual needs, and this application embodiment does not limit this. In some examples, the plurality of first connecting parts 12 can be arranged sequentially at intervals along the connecting direction of the first connecting parts 12 and the second connecting parts 22. The distribution of the plurality of second connecting parts 22 can be determined according to actual needs, and this application embodiment does not limit this. The plurality of second connecting parts 22 can be arranged sequentially at intervals along the first direction.

[0041] In some embodiments, the control box 1 may further include a first side plate 30 and a second side plate 40, and the first control board 10, the first side plate 30, the second side plate 40 and the second control board 20 are sequentially connected and enclosed.

[0042] like Figures 1 to 5 As shown, on the other hand, this application embodiment provides an air conditioner 100, including the electrical control box 1 provided in any of the above embodiments. The air conditioner 100 provided in this application embodiment has the above-mentioned electrical control box 1, which can improve assembly efficiency, maintenance and disassembly convenience, and structural stability.
