Description

A kind of anti-light leak automotive acoustics

Technical field

The utility model relates to self-propelled vehicle equipment, relates in particular to a kind of anti-light leak automotive acoustics.

Background technology

Electronic product is especially in the auto audio equipment product, because need night time operation, the function character functional character of button needs light, so that the operator understands the function of button, but except function character functional character, the place, other slit of the periphery of button and panel can not light leak, in order to avoid influence the visibility of printing opacity button character and operator's comfort level.

Because button requires printing opacity, so button will be used the sizing material injection moulding of printing opacity, usually only in button face oil spout shading, and the button shank portion that cooperates with panel needn't oil spout or oil spout imperfect, normally not shading, then can on panel, add the inside that the glue frame reaches button cap and come shading if button cap is enough big, automotive acoustics partial cutaway schematic as shown in Figure 1, it comprises a pcb board 1, one deck conducting resinl 2 is laid on pcb board 1 surface, panel 3 and button 4 are installed on the top of pcb board 1 and conducting resinl 2, the button cap 41 of button 4 is arranged in the panel 3, corresponding to each button cap 41, set up corresponding LED lamp 11 in the pcb board 1, LED lamp 11 is used to shine the function character functional character of button cap 41 button faces, purpose for anti-light leak, as shown in Figure 1, on panel 3, add glue frame 31 and reach the inside of button cap 41, like this, the glue frame 31 of LED lamp 11 both sides has just produced the effect of shading to LED lamp 11, make the range of exposures of LED lamp 11 be defined in the region S, with other place, slit light leak of the periphery of avoiding button 4 and panel 3.

If the photoetching word on the less or button cap of button is bigger, then be unsuitable for adopting above-mentioned glue frame to block the light leak part of button, have only by all parts (except function character functional character/printing opacity word place) of button cap are sprayed oil, this just requires button (cap) bigger with the gap of panel, this processing method very easily produces the phenomenon of card button, and the feel of button is very poor.In some push-button design, for adapting to the translation effect of button, require the button handle of button and the panel part gap that matches very little and will add guide groove, what have also will be coated with lubricating oil, yet the button handle is not allow oil spout in this case, therefore, prior art button reliability less for those button size, that arrangement is closeer is low, and conformability is not strong.

Summary of the invention

The purpose of this utility model is to provide a kind of anti-light leak automotive acoustics, and button reliability less for button size in the prior art to overcome, that arrangement is closeer is low, the shortcoming that conformability is not strong.

The anti-light leak automotive acoustics that the utility model adopted, comprise a pcb board, one deck conducting resinl is laid on the pcb board surface, panel and button are installed on the top of pcb board, and the button cap of button is arranged in the panel, corresponding to each button cap, set up corresponding LED lamp in the pcb board, the LED lamp is used to shine the function character functional character of button cap button face, it is characterized in that: corresponding to each LED lamp, set up one on the conducting resinl and enclose frame accordingly.

Described LED lamp is in and encloses frame inside, and this encloses the inside that frame stretches into button cap.

The described frame that encloses is a quadrangle sealing framework, both-side opening up and down, and the LED lamp is placed in the open lower side middle part.

The beneficial effects of the utility model are: in the utility model, corresponding to each LED lamp, set up one on the conducting resinl and enclose frame accordingly, enclose frame (adopting light tight) and can limit the range of exposures of LED lamp as black, avoid the periphery of button and other place, slit light leak of panel, the frame that encloses of the present utility model directly is attached on the conducting resinl, need on panel, not add other light-blocking member, conducting resinl of the present utility model and the integrated design of enclosing frame, good shading effect, features simple structure, help cost-cutting, the one-time formed frame reliability height that encloses, application of the present utility model and button size are irrelevant, can be applied to the button of various (bigger or less) size preferably, and the closeer button of arrangement, therefore, the utility model reliability height, conformability is strong.

In the utility model, enclose frame and adopt quadrangle sealing framework, both-side opening up and down, the LED lamp is placed in the open lower side middle part, encloses the inside that the frame upside stretches into button cap, and it is simple in structure, reliable, has further improved practicality of the present utility model.

Description of drawings

Fig. 1 is the prior art partial cutaway schematic;

Fig. 2 is the assembly surface scheme drawing of panel and button in the utility model;

Fig. 3 is the utility model exploded perspective view;

Fig. 4 is that the utility model is along the A-A partial cutaway schematic.

The specific embodiment

With embodiment the utility model is described in further detail with reference to the accompanying drawings below:

According to Fig. 2, Fig. 3 and Fig. 4, the utility model comprises a pcb board 1, as shown in Figure 3 and Figure 4, one deck conducting resinl 2 is laid on pcb board 1 surface, panel 3 and button 4 are installed on the top of pcb board 1, Fig. 2, Fig. 3 and shown in Figure 4, the button cap 41 of button 4 is arranged in the panel 3, corresponding to each button cap 41, set up corresponding LED lamp 11 in the pcb board 1, LED lamp 11 is used to shine the function character functional character of button cap 41 button faces, and in the present embodiment, the sizing material body of plastic cement button 4 is printing opacities, at button cap 41 part oil spouts lacquers (promptly exposing panel 3 parts), function character functional character is fallen the paint part and printing opacity by laser engraving, and plastic rubber panel 3 adopts light tight sizing material, and conducting resinl 2 adopts the sizing material of light tight (as black).

As shown in Figure 3 and Figure 4, corresponding to each LED lamp 11, set up one on the conducting resinl 2 and enclose frame 21 accordingly, LED lamp 11 is in and encloses frame 21 inside, and this encloses the inside that frame 21 stretches into button cap 41.In the present embodiment, as shown in Figure 3 and Figure 4, enclose frame 21 and be quadrangle sealing framework, both-side opening up and down, LED lamp 11 is placed in the open lower side middle part, encloses the inside that frame 21 upsides stretch into button cap 41.

As shown in Figure 4, the range of exposures of LED lamp 11 is the 180 ° of scopes in top, because enclosing frame 21 can be limited to the range of exposures of LED lamp 11 in the regional M, LED lamp 11 can only be radiated in the top function character functional character scope of button cap 41, the spread of LED lamp 11 also is in the light tight scope of button cap 41 oil spouts lacquer, thereby the utility model has solved the light leak problem well.

In sum, although basic structure of the present utility model is specifically set forth by the foregoing description, under the prerequisite that does not break away from the utility model main idea, according to above-described inspiration, those of ordinary skills can not need to pay creative work can implement multiple conversion/alternative form or combination, repeats no more herein.
