Description

Electronic installation

Technical field

The present invention relates to a kind of electronic installation.

Background technology

Electronic installation is inhaled the top display like automobile, generally comprises framework and is arranged on display screen and the power knob on the framework, and power knob is electrically connected with display screen through touch-switch.When pressing power knob, the touch-switch conducting is to open display screen; When pushing power knob once more, touch-switch breaks off, to close display screen.Touch-switch is realized the conducting and the disconnection of touch-switch through the stressed springing of interior metal shell fragment.

Yet; The interior metal shell fragment of touch-switch through long-term the use after, be easy to generate elastic fatigue, may produce and still can not effectively cut off the situation of electronic device power after pushing power knob; Cause electronic installation to be in "on" position for a long time, reduced the useful life of electronic installation.

Summary of the invention

In view of above content, be necessary to provide a kind of electronic installation that has than the long life.

A kind of electronic installation; It comprises framework, is arranged at the power knob on the framework, the support that links to each other with power knob, and be connected on the framework optoelectronic switch, optoelectronic switch comprises reflector and the receiver that is oppositely arranged; Be formed with switchboard on the support; Switchboard can switch between the primary importance and the second place, and switchboard partly inserts between said reflector and the receiver when primary importance, and switchboard is deviate between said reflector and the receiver when the second place.

Above-mentioned electronic installation can make support become the state that breaks away from optoelectronic switch by the state that stretches into optoelectronic switch through the operating power button; So that electronic installation switches cutting out with opening; Simple in structure and after long-term the use, still can effectively use; Can not make electronic installation produce the situation of long-term energising, thereby make electronic installation have long useful life.

Embodiment

Below in conjunction with accompanying drawing and execution mode electronic installation of the present invention is done further to specify.

See also Fig. 1 to Fig. 4, the electronic installation 30 of embodiment of the present invention comprises framework 31 and is arranged at display screen 32, power knob 33, printed circuit board (PCB) 34, optoelectronic switch 35, support 36 and the power supply 37 on the framework 31.In the present embodiment, electronic installation 30 is inhaled the top display for automobile, and optoelectronic switch 35 is a Photoelectric infrared switch.

Framework 31 comprises substrate 311, and corresponding display screen 32 offers holding tank (figure is mark not) on it, and corresponding power button 33 offers accommodation hole (figure is mark not).The back side of substrate 311 is formed with installation portion 3111 (as shown in Figure 2) in the position of contiguous power knob 33.

Printed circuit board (PCB) 34 is fixed on the installation portion 3111 of substrate 311, and is electrically connected with display screen 32 and power supply 37.

Optoelectronic switch 35 is electrically connected on printed circuit board (PCB) 34, and it comprises the base plate 351 that is fixedly connected with printed circuit board (PCB) 34, and the reflector 352 and the receiver 353 that are connected in base plate 351 opposite ends.

Connecting plate 362 that support 36 comprises the supporting bracket 361 that links to each other with power knob 33, formed by supporting bracket 361 terminal vertical extent and the switchboard 363 that forms away from the terminal vertical extent of supporting bracket 361 by connecting plate 362.Switchboard 363 parts are inserted between the reflector 352 and receiver 353 of optoelectronic switch 35.In the present embodiment, switchboard 363 comprises main part 3631 and the insertion end 3632 that is extended to form by main part 3631 ends, and insertion end 3632 is the right-angled trapezium shape.

When using electronic installation 30, push power knob 33, support 36 is along moving away from the direction of substrate 311, so that switchboard 363 is deviate from (as shown in Figure 4) from optoelectronic switch 35.At this moment, the receiver 353 of optoelectronic switch 35 can receive the light that reflector 352 sends, and sends open command through printed circuit board (PCB) 34 to power supply 37, thereby opens display screen 32.When need close closing electronic device 30; Only need retract power knob 33, so that between the reflector 351 that switchboard 363 gets into optoelectronic switch 35 again and the receiver 353 (as shown in Figure 3), because the light that reflector 352 sends is by switchboard 363 obstructs; Receiver 353 can not receive the light that sends; Optoelectronic switch 35 senses switchboard 363 and gets into, and sends shutdown command through printed circuit board (PCB) 34 to power supply 37, thereby closes display screen 32.

Electronic installation 30 can make support 36 become the state that breaks away from optoelectronic switch 35 by the state that stretches into optoelectronic switch 35 through operating power button 33; So that electronic installation 30 switches cutting out with opening; Simple in structure and after long-term the use, still can effectively use; Can not make electronic installation 30 produce the situation of long-term energising, thereby make electronic installation 30 have long useful life.

Be appreciated that printed circuit board (PCB) 34 also can be connected with other inner electronic components of electronic installation 30, like loud speaker etc., to control the opening and closing of these electronic components through optoelectronic switch 35 and printed circuit board (PCB) 34.In addition, also the elastic lock structure can be set between support 36 and the framework 31, so that after power knob 33 is pressed, support 36 and framework 31 lockings, promptly switchboard 363 keeps breaking away from the state of optoelectronic switches 35, and electronic installation 30 is opened; After pushing power knob 3 once more, support 36 unlocks with framework 31, and promptly switchboard 363 gets in the optoelectronic switch 35 again, and electronic installation 30 cuts out.

In addition, those skilled in the art also can do other variation in spirit of the present invention, and certainly, these all should be included in the present invention's scope required for protection according to the variation that the present invention's spirit is done.
