Detailed ways

1 to 3, according to an embodiment of the present invention, a display panel assembly includes a panel body 10, a display panel 1, a display box 3 and a PCB board 4, one side of the display box 3 is connected to the The display panel 1 is sealed and connected, and the other side opposite to the sealed connection of the display box 3 is set as an opening, and is fixedly connected with the panel body 10 ; the PCB board 4 is arranged in the display box 3 .

The opening side of the display box 3 is directly fixedly connected to the panel body 10, which is equivalent to using the panel body 10 as a sealing cover to seal the PCB board 4 in the display box 3; and the other side of the display box 3 is sealed and connected to the display panel 1 , cancel the upper cover structure of the display box 3, reduce the assembly parts, and improve the assembly efficiency.

An elastic structure 15 is provided on the panel body 10, and the elastic structure 15 leans against the PCB board 4, so that the PCB board 4 is closely attached to the display box 3, and the silicone pad covered on the surface of the display box 3 is in flexible contact with the display panel 1, so as to Guaranteed display effect.

A groove 23 is designed on the panel body 10, and the display box 3 is directly fixed in the groove 23, so as to prevent the display panel 1 from protruding and affecting the appearance of the product.

Preferably, the display box 3 is clamped in the groove 23, such as using the fixing buckle 6 shown in FIG. 2 for snap connection, no screws are used for fixing, and the assembly efficiency is improved.

Positioning structure is provided in groove 23 and/or on display case 3, is used for limiting the position that described display case 3 is located in described groove 23, as display case 3 is provided with locating pin 5, facilitates both quickly snap in accurately.

The display panel assembly of the present invention cancels the cover structure of the display box 3, and the assembly method is no longer fixed by screws, which improves the assembly efficiency; and the large-screen display has a large-area display area, which can realize the display of large-area patterns on the wall-mounted machine. It subverts the traditional appearance display, making the appearance of the wall-mounted machine more aesthetically pleasing, and meeting consumers' requirements for appearance.

The present invention considers the problem of the space occupied by the display structure while considering the large-area display, and designs a groove 23 on the panel body 10. At the same time, in order to ensure that the PCB board 4 is close to the display box 3, an elastic structure 15 is designed in the groove 23 to Guaranteed display reliability. The large-screen display is inserted into the groove 23 through the positioning pin 5 , and the large-screen display and the panel body 10 are assembled and fixed through the fixing buckle 6 .

Furthermore, several PCB boards 4 are provided, which are respectively clamped on the display box 3 . Because the large-screen display is adopted in this technical solution, the displayed pattern area is relatively large. In order to ensure the reliability of the display, several PCB boards 4 are provided, as shown in Figure 2. Through the lamppost structure on the display box 3 and through the silk-screened pattern on the display panel 1 , the pattern display of the wall-mounted machine is realized.

The display box 3 is bonded on the display panel 1 by glue, especially 3M glue or other similar types of glue. After the glue is compressed, the thickness is 1 mm and the width is 15 mm. Guarantee the reliability of pasting.

Preferably, the panel display structure further includes a flexible pad disposed between the display box and the display panel. The flexible pads include rubber pads 2, silicone pads, etc., or other similar soft structure pads. Let's take the rubber pad 2 as an example for illustration:

The rubber pad 2 is located between the display panel 1 and the display box 3, and its thickness is slightly greater than the thickness of the glue. The thickness of the rubber pad 2 is 0.1-0.2mm thicker than the thickness of the glue, so as to ensure that the rubber pad 2 and the display panel 1. Tightly stick to avoid light leakage during display and ensure the high brightness of the pattern display.

The display box 3 can be set as a hollowed-out state, and the display pattern can be replaced with other patterns arbitrarily, and the display pattern can be screen-printed on the panel or by means of pasting a film or the like.

An air conditioner includes the above-mentioned display panel assembly. The air conditioner includes an air conditioner and a cabinet machine.

The present invention mainly omits some components in the display device, improves the assembly method of the traditional air conditioner, and uses the groove 23 device to replace the display cover, greatly improving the assembly efficiency and saving space. On this basis, a large-area display pattern can be realized to meet the needs of modern consumers for air-conditioning displays, and it is no longer a small and monotonous display, improving user experience.

Those skilled in the art can easily understand that, on the premise of no conflict, the above-mentioned implementation manners can be freely combined and superimposed.

The above descriptions are only 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 principles of the present invention should be included in the protection of the present invention. within range. The above is only a preferred embodiment of the present invention, it should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of the present invention, some improvements and modifications can also be made, these improvements and modifications It should also be regarded as the protection scope of the present invention.
