Description

The integrated structure of the display panel button of the indoor unit of the air conditioner

technical field

The invention relates to an air conditioner indoor unit. In particular, it relates to an air-conditioning indoor unit display panel button integration structure with accurate buttons and material saving.

Background technique

At present, the button modes of the air conditioner indoor units seen on the market are roughly the same, and all adopt independent button structures.

FIG. 1 is a schematic diagram of an exploded structure of a display unit in the prior art.

As shown in Figure 1, a circuit board box 1 is arranged on the display part of the air-conditioning indoor unit, a display circuit board 2 is installed on the circuit board box 1, and a switch 9 corresponding to the switch 9 is installed on the front of the display circuit board 2. The button part 3 and the display panel 4 are covered on the circuit board box 1 again, wherein each button 7 on the button part 3 passes through the slot 8 on the display panel 4, and stretches to the front of the display panel 4, and then The part of keys exposed in front of the display panel 4 is sprayed or electroplated.

The display part structure in which the button part 3 and the display panel 4 are assembled separately, because the button, the display panel and the display circuit board are installed independently respectively, the switch clearance requirement between the button and the display circuit board is relatively high, otherwise, when the button is pressed, it is easy to Poor contact occurs. Moreover, the independent structure of the button has high manufacturing cost and cumbersome production operations. It is necessary to fix the button on the circuit board box with screws (two) separately in the production line, and then press the circuit board box tightly to the display panel to expose the button. In the process, special personnel are required to fix the buttons.

Contents of the invention

The technical problem to be solved by the present invention is to provide an integrated structure of buttons on the display panel of an air-conditioning indoor unit with accurate buttons, material saving and simple production operations.

The technical solution adopted in the present invention is: an integrated structure of the display panel buttons of the indoor unit of the air conditioner, including a circuit board box arranged on the display part of the indoor unit of the air conditioner, a display circuit board installed on the circuit board box, and a display circuit board installed on the circuit board A display panel with integrated buttons is arranged on the front of the box and the display circuit board. The display panel is a thin plate structure.

The upper part of the display panel corresponds to the upper part of the display circuit board and has a display window for displaying the state of the air conditioner. The lower part of the display panel corresponds to the lower part of the display circuit board and is provided with buttons integrally connected with the display panel. The buttons and the display panel are connected as a whole through ribs integrally formed with them.

The present invention transplants the button function to the display panel, and makes the combination of the button and the display panel into an integrated design, that is, a new button structure is formed at the corresponding position of the display panel, and the connection with the display panel adopts a middle reinforced structure to achieve a good connection . This structure saves the consumption of raw materials and reduces the cost. One process is reduced in the production line, and there is no need to fix the buttons with screws, the production operation is simple, and the assembly productivity is improved. Moreover, the button action stroke of the present invention is reduced, which overcomes the phenomenon of poor contact of the buttons.

Detailed ways

The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

FIG. 2 is a schematic diagram of an exploded structure of a display portion of the present invention; FIG. 3 is a schematic structural diagram of a display panel of the present invention.

As shown in the figure, the integrated structure of the display panel buttons of the air-conditioning indoor unit includes a circuit board box 1 arranged on the display part of the air-conditioning indoor unit, a display circuit board 5 is installed on the circuit board box 1, and the circuit board box 1 and A display panel 6 with integrated keys is arranged on the front of the display circuit board 5 . The display panel 6 is a thin plate structure with a thickness of 1.5-3.5mm.

The upper part of the display panel 6 corresponds to the upper part of the display circuit board 5, and has a display window 11 for displaying the state of the air conditioner. The lower part of the display panel 6 corresponds to the lower part of the display circuit board 5, and is provided with a Connected keys 10.

The display panel 6 has a slot 13 at the position where the button is provided, and the button 10 having the same material as the display panel 6 is arranged in the slot 13. Between the button 10 and the display panel 6, the button 10 is integrated with them. Formed ribs 12 are integrally connected.

When the present invention is assembled, at first, the display circuit board 5 is fixed on the circuit board box 1, and then the display panel 6 is installed on the front of the circuit board box 1 and the circuit board 5, and then a sticker is pasted on the front of the display panel 6. layer with its corresponding plastic film. The buttons 10 integrally connected with the display panel 6 correspond to the switches 9 on the circuit board 5 respectively. When in use, since the display panel 6 is a thin plate structure, the buttons 10 on it are easy to contact with the switches 9 on the circuit board 5, so the phenomenon of poor contact between the buttons 10 and the switches 9 is overcome.
