Abstract

The utility model discloses a structure for realizing backlight of an automobile air-conditioning controller turn button integrated button, comprising a turn button, a transparent turn button light guiding support, an encoder, an outer ring backlight and a button cap, wherein the outer ring backlight is arranged below the transparent turn button light guiding support, an inner side and an outer side of the button cap are respectively provided with an inner ring symbol and an outer ring symbol, an inner ring backlight is arranged inside of the encoder, the inner ring backlight is arranged below the inner ring symbol of the button cap, a light of the outer ring backlight can irradiate onto the outer ring symbol of the button cap through a light guiding flat on the transparent turn button light guiding support, both the outer ring backlight and the inner ring backlight are arranged on a circuit board. According to the structure for realizing backlight of the automobile air-conditioning controller turn button integrated button with the above special structure, the light of the outer ring backlight can irradiate onto the outer ring symbol of the button cap through a light guiding surface on the light guiding flat, thereby realizing lighting for the outer ring symbol; and a light of the inner ring backlight can directly irradiate onto the inner ring symbol of the button cap, thereby realizing lighting for the inner ring symbol.

Description

A kind of structure that realizes the integrated key-press backlight of automotive air-conditioning controller knob

Technical field

The utility model relates to a kind of structure that realizes the integrated key-press backlight of automotive air-conditioning controller knob.

Background technology

The general structure of realization backlight of the integrated button of existing air-conditioning controller knob is: all backlights all are positioned at encoder inside, and the light direct projection is on the Internal and external cycle symbol on the button cap.Because the encoder dimensions is limited, can't select arbitrarily, wherein large-sized encoder specification is less, and costs an arm and a leg, and delivery cycle is long, is not suitable for selecting; Undersized encoder relative price is cheap, and delivery cycle is short, is fit to select for use.But small size encoder inner space is little, behind the arranged keys switch, does not have redundant space to arrange and is used to arrange backlight; The backlight quantity that causes arranging is few; Outer ring symbol on the button cap is backlight to be difficult to evenly, and the difficult raising of brightness, thereby influences the inner visual effect of car load.

The utility model content

The utility model technical problem to be solved is to the problem that exists in the prior art a kind of structure that realizes the integrated key-press backlight of automotive air-conditioning controller knob to be provided, and its objective is to be easy to adjust the backlight of the integrated button of knob, and versatility is good.

The technical scheme of the utility model is that the structure of the integrated key-press backlight of this kind realization automotive air-conditioning controller knob comprises knob, transparent knob leaded light support, encoder, outer ring backlight, button cap; The outer ring backlight is positioned at the below of transparent knob leaded light support; The inboard of described button cap, the outside are respectively equipped with inner ring symbol, outer ring symbol; The inside of described encoder is provided with the inner ring backlight, and described inner ring backlight is positioned at the below of button cap inner ring symbol.

The light of described outer ring backlight is mapped on the outer ring symbol on the button cap through the leaded light flat board on the transparent knob leaded light support.

Described outer ring backlight and inner ring backlight are installed on the circuit board.

Structure with integrated key-press backlight of this kind realization automotive air-conditioning controller knob of above-mentioned special construction has the following advantages:

1. this kind structure of realizing the integrated key-press backlight of automotive air-conditioning controller knob all is furnished with backlight inside and outside of encoder; The outside backlight of encoder is positioned at the below of transparent knob leaded light support; Light shines on the outer ring symbol on the button cap through the light guiding surface on the leaded light flat board, realizes the illumination of outer ring symbol; The inner backlight of encoder is positioned at the below of button cap inner ring symbol, and the light direct projection has realized the illumination of inner ring symbol on the inner ring symbol of button cap.

2. this kind realizes that its encoder of structure of the integrated key-press backlight of automotive air-conditioning controller knob need not to change according to the change in size of knob, has improved versatility.

3. the structure of the integrated key-press backlight of this kind realization automotive air-conditioning controller knob can be used little encoder, has reduced cost; And the even back degree is better, and brightness is prone to regulate.

Description of drawings

Below in conjunction with accompanying drawing the utility model is described further:

Fig. 1 is the structural representation of the utility model.

Fig. 2 is the sectional structure sketch map of structure shown in Figure 1.

The sketch map that Fig. 3 transmits for the utility model light.
