[0033] In order to make the purpose, technical scheme and advantages of the present application more clear and explicit, the present application will be further described in detail below in combination with the drawings and examples.

[0034] It should be noted that in the description of the present application, the terms indicating the direction or position relationship of “up”, “down”, “left”, “right”, “vertical”, “horizontal”, “inner”, “outer” and the like are based on the direction or position relationship shown in the drawings, which is only for the convenience of description, and does not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. In addition, the terms “first” and “second” are only for the purpose of description, and cannot be understood as indicating or implying relative importance.

[0035] Referring to Figures 1-7 It is an embodiment of the sheet metal connecting structure of the present application. The sheet metal connecting structure comprises a side plate 100, a sheet metal support 200, and a fastener (not shown) for fixing the side plate 100 and the sheet metal support 200. The fastener can be a screw, a bolt or the like.

[0036] As Figure 2The side plate 100 is provided with an abutting portion 110 and a fixing portion 120 protruding from the side surface of the side plate 100. The fixing portion 120 has a mounting plane 121, and a threaded hole is formed in the mounting plane 121 for mounting a fastener.

[0037] The sheet metal bracket 200 is vertically abutted to the side surface of the side plate 100 between the abutting portion 110 and the fixing portion 120. The side edge of the sheet metal bracket 200 abutting the side surface of the side plate 100 is provided with a bent portion 210 bent towards the fixing portion 120. A through hole is formed in the bent portion 210 for mounting a fastener. As shown in Figure 4 and Figure 5 The bent portion 210 is outwardly tilted relative to the mounting plane 121 of the fixing portion 120, and has an included angle a with the mounting plane 121, i.e., the bent portion 210 is not parallel to the mounting plane 121 of the fixing portion 120. The side surface of the sheet metal bracket 200 is abutted to the abutting portion 110 of the side plate 100.

[0038] The bent portion 210 is fixedly connected to the fixing portion 120 by the fastener, and the fastener deforms the bent portion 210 to be attached to the mounting plane 121 of the fixing portion 120.

[0039] The sheet metal connecting structure has the included angle between the bent portion 210 and the mounting plane 121. During the tightening of the fastener, the bent portion 210 is deformed to be tightly attached to the fixing portion 120 due to the fastening effect of the fastener and the limiting effect of the abutting portion 110 of the side plate 100. During the deformation, the sheet metal bracket 200 is tightly pressed against the abutting portion 110 of the side plate 100, which enhances the fixing force and generates self-locking, thereby improving the strength. One fastener is used to enhance the pressure at the abutting portion 110 by deforming the sheet metal, which has the same fixing effect as the fastener at the abutting portion 110, reduces the use of screws and other fasteners, reduces the cost, and improves the installation efficiency. Meanwhile, the sheet metal connecting structure has strong portability and universality for the connection of sheet metal parts of different structures.

[0040] When the sheet metal bracket 200 is used in places where it is not frequently opened and closed, the deformation of the sheet metal will be increased during the installation and disassembly due to improper operation, i.e., the included angle between the bent portion 210 and the mounting plane 121 is increased. According to the characteristics of the sheet metal connecting structure, the connection can be more reliable when reconnected.

[0041] Further, the side plate 100 is provided with a slot 130, and the side edge of the metal bracket 200 is provided with an L-shaped claw portion 220 extending outward, which is inserted into the slot 130. During installation, the claw portion 220 of the metal bracket 200 is inserted into the slot and slid downward, and the side plate 100 is embedded into the notch of the claw portion 220. The claw portion 220 plays a role of pre-fixing and positioning, and the bending portion 210 can also press the inner wall of the slot 130 during the process of fastening deformation, thereby enhancing the fixing force.

[0042] In the embodiment, the bending portion 210 is arranged at the middle of the side edge of the metal bracket 200, and the claw portion 220 is provided with two portions arranged above and below the bending portion 210. The abutting portion 110 of the side plate 100 is also provided with two portions, and each of the two slots 130 and the fixing portion 120 is provided with one portion. The metal bracket 200 is limited and fixed by the two claw portions 220 and the two abutting portions 110.

[0043] The installation plane 121 of the fixing portion 120 is preferably an inclined plane having a certain angle with the plane of the side plate 100, as shown in Figure 6 The inclined plane is convenient for screwing from the front. In another embodiment, the installation plane 121 of the fixing portion 120 can also be parallel to the plane of the side plate 100.

[0044] The cross section of the fixing portion 120 is preferably triangular, and the inclined plane of one side of the triangle forms the installation plane 121, which has a simple structure and low manufacturing cost.

[0045] In the embodiment, the side plate 100 is also a metal piece, which is formed into a rectangular abutting portion 110 by cutting and right-angle bending.

[0046] The angle a between the bending portion 210 and the installation plane 121 is preferably in the range of 3° to 10°. In other embodiments, the range of the angle is not limited, and the bending portion 210 of the metal bracket 200 can also be deformed greatly after improper operation, which can also achieve the effect of increasing the fixing force and improving the connection reliability.

[0047] As shown in Figure 7 , the metal bracket 200 is provided with a bending fixing portion 230 away from the side edge of the side plate 100, which can be fixedly connected with other components by screws and other fasteners. The bending fixing portion 230 and the fixing mode of other components are ordinary screw connection.

[0048] As shown in Figure 1As shown, the application further comprises an electric control box, the electric control box comprising a box body 1 and an electric control board 300 arranged in the box body 1, the box body 1 comprising a plurality of side plates 100 which are closed together. In the embodiment, the box body 1 comprises three side plates 100, and the box body 1 is of an integral molding structure. The electric control board 300 is fixed on the side of the metal sheet support 200. One side edge of the metal sheet support 200 is fixed through the metal sheet connecting structure as described above, and the other side edge is fixed to the other side plate 100 through the fastener. In the installation, the metal sheet support 200 is first inserted in the direction of the side plate 100, the claw part 220 is inserted into the slot 130 and slides downward, and after being clamped, the metal sheet support 200 is rotated inward and closed, and then the bending part 210 of the metal sheet support 200 is fastened to the fixing part 120 through the screw, and finally the other side of the metal sheet support 200 is fastened through the screw.

[0049] The application further comprises an air conditioner, which comprises the electric control box as described above.

[0050] The above embodiments are only used to illustrate the technical solutions of the application, but not to limit the application; although the application has been described in detail with reference to the foregoing embodiments, the technical solutions recorded in the foregoing embodiments can still be modified by those skilled in the art, or some technical features can be replaced equivalently; and the modification or replacement does not make the essence of the corresponding technical solution deviate from the spirit and scope of the technical solutions claimed by the application.
