[0026] Reference Figure 1 An air conditioner display assembly according to an embodiment of the present invention includes a rear shell 100, a fixing frame 200, a protective cover 300, and a main board 400. The rear shell 100 has a mounting cavity 110; the fixing frame 200 is disposed in the mounting cavity 110 and fixed to the rear shell 100, and the fixing frame 200 has a clearance hole 210; the protective cover 300 is installed on the side of the fixing frame 200 away from the rear shell 100, and the protective cover 300 has a receiving cavity 310 that opens toward the rear shell 100; the main board 400 is disposed in the mounting cavity 110 and located between the rear shell 100 and the fixing frame 200, and the main board 400 is fixedly installed on the rear shell 100. The main board 400 is provided with a display element 410, which passes through the clearance hole 210 and is inserted into the receiving cavity 310. There are gaps between the main board 400 and the fixing frame 200, and between the display element 410 and the inner wall of the receiving cavity 310.

[0027] Reference Figure 1 The air conditioner display assembly provided by this utility model has a main board 400 fixed to the rear shell 100 with gaps between it and the fixing frame 200 and the protective cover 300. Therefore, when the protective cover 300 is pressed, the pressure on the protective cover 300 will not be directly applied to the main board 400, but will be applied sequentially to the fixing frame 200 and the rear shell 100. This avoids the main board 400 being directly subjected to pressure, protects the main board 400, and ensures product quality.

[0028] In addition, the back cover 100, fixing frame 200 and protective cover 300 of the monitor assembly are all installed as a whole. The monitor assembly can be assembled first and then installed on the air conditioner box, which is convenient for installation and later maintenance.

[0029] Reference Figure 1 According to some embodiments of the present invention, the gap between the front surface of the display element 410 and the bottom wall of the receiving cavity 310 is greater than 4mm, so as to allow sufficient space for the protective cover 300 to deform under pressure.

[0030] Reference Figures 1 to 3 According to some embodiments of this utility model, the fixing frame 200 and the rear shell 100 are connected and fixed by multiple bolts. Thus, the fixing frame 200 can be reliably fixed to the rear shell 100, and the fixing frame 200 and the rear shell 100 can also be disassembled, facilitating later disassembly and recycling of the components. A first positioning structure for positioning the fixing frame 200 is provided between the rear shell 100 and the fixing frame 200. Therefore, during assembly, the fixing frame 200 can be positioned using the first positioning structure to align the holes for mounting bolts between the fixing frame 200 and the rear shell 100, thereby making bolt installation between the fixing frame 200 and the rear shell 100 simpler, more convenient, and more accurate.

[0031] Reference Figure 3 According to some embodiments of the present invention, the first positioning structure includes three positioning ribs 120 and three positioning grooves 230. The mounting cavity 110 has four cavity walls arranged in a rectangular shape. The three positioning ribs 120 are correspondingly disposed on three of the four cavity walls. The three positioning grooves 230 are placed on the fixing frame 200 and are correspondingly disposed on the three positioning ribs 120. The positioning ribs 120 are inserted into the corresponding positioning grooves 230. With the above arrangement, the first positioning structure can effectively position the fixing frame 200.

[0032] In other embodiments, the first positioning structure described above may also be configured in other ways. For example, the first positioning structure may include a stepped groove provided on the periphery of the mounting cavity 110. The stepped groove has a rectangular cross-section, and a part of the fixing frame 200 may be engaged in the stepped groove.

[0033] Reference Figure 1 and Figure 3 According to some embodiments of this utility model, the motherboard 400 and the rear shell 100 are connected and fixed by multiple bolts. Thus, the motherboard 400 can be securely fixed to the rear shell 100, and the motherboard 400 and the rear shell 100 can also be disassembled, facilitating later disassembly and recycling of components. The rear shell 100 is provided with a second positioning structure for positioning the motherboard 400. Therefore, during assembly, the motherboard 400 can be positioned using the second positioning structure to align the holes for mounting bolts between the motherboard 400 and the rear shell 100, making bolt installation between the motherboard 400 and the rear shell 100 simpler, more convenient, and more accurate.

[0034] Reference Figure 3According to some embodiments of the present invention, the second positioning structure includes three support parts 130 arranged in a triangle. All support parts 130 are provided with positioning steps 131. The main board 400 is rectangular, and the three sides of the main board 400 are correspondingly placed on the positioning steps 131 on the three support parts 130. Thus, the second positioning structure can position the main board 400 from three different positions, making the positioning more accurate and stable.

[0035] It is conceivable that in other embodiments, the second positioning structure described above may also adopt other configuration methods. For example, the second positioning structure includes a number of positioning posts, and positioning holes are provided on the motherboard 400, with each positioning post inserted into a corresponding positioning hole.

[0036] Reference Figure 1 and Figure 3 According to some embodiments of this utility model, the fixing frame 200 has a recess 220 on one side away from the rear shell 100. The periphery of the recess 220 is flush with the periphery of the mounting cavity 110. One end of the protective cover 300 is located in the recess 220, and the other end of the protective cover 300 protrudes from the recess 220. Thus, the periphery of the recess 220 can be used to increase the strength of the fixing frame 200, and the periphery of the recess 220 and the rear shell 100 can be simultaneously supported on the housing 500 of the air conditioner unit.

[0037] Reference Figure 1 , Figure 3 and Figure 4 According to some embodiments of this utility model, the bottom wall of the recess 220 is provided with at least three elastic buckles 240, and the peripheral wall of the receiving cavity 310 is provided with at least three locking holes 320. All the elastic buckles 240 are inserted into the receiving cavity 310 and are correspondingly locked into all the locking holes 320. Thus, the protective cover 300 and the fixing frame 200 are installed using elastic buckles 240, which facilitates the installation of the protective cover 300.

[0038] Reference Figure 4According to some embodiments of this utility model, the elastic buckle 240 includes an elastic connecting portion 241 and a snap-fit ​​protrusion 242. The elastic connecting portion 241 is connected to the bottom wall of the recess 220 and extends axially along the receiving cavity 310. The snap-fit ​​protrusion 242 is disposed at the top of the elastic connecting portion 241 and snaps into the corresponding snap-fit ​​hole 320. A portion of the snap-fit ​​protrusion 242 protrudes from the outer peripheral wall of the protective cover 300 to cooperate with the fixing frame 200 to clamp the housing 500 of the air conditioner chassis. Therefore, when installing the display assembly onto the chassis housing 500, it is only necessary to insert the protective cover 300 directly into the mounting hole 510 on the chassis housing 500. The snap-fit ​​protrusion 242 on the elastic buckle 240 and the fixing frame 200 cooperate to clamp the chassis housing 500, thereby fixing the display assembly in the mounting hole 510 of the chassis housing 500, which is convenient for installation.

[0039] Of course, in other embodiments, the rear cover 100 and the chassis housing 500 can also be connected by bolts to fix the display assembly to the chassis housing 500, or the protective cover 300 can be glued to the mounting hole 510 of the chassis housing 500 to fix the display assembly to the chassis housing 500.

[0040] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0041] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
