Electronic device

The present invention relates to an electronic device.

Electronic devices, such as automotive ceiling displays, generally include a frame and a display and power button disposed on the frame, and the power button is electrically connected to the display by a tact switch. When the power button is pressed, the tact switch is turned on to turn on the display; when the power button is pressed again, the tact switch is turned off to turn off the display. The tact switch is energized and bounced by the internal metal dome to achieve the on and off of the tact switch.

However, after the long-term use of the internal metal shrapnel of the tact switch, elastic fatigue is likely to occur, and the power supply of the electronic device may not be effectively cut off after pressing the power button, causing the electronic device to be energized for a long time, reducing the electronic device. Service life.

In view of the above, it is necessary to provide an electronic device having a long service life.

An electronic device includes a frame, a power button disposed on the frame, a bracket connected to the power button, and a photoelectric switch connected to the frame, the light The electric switch comprises a bottom plate, a correspondingly disposed transmitter and a receiver, and the transmitter and the receiver are respectively connected to opposite ends of the bottom plate, and the switch plate is formed on the bracket, the bracket further comprises a support plate connected to the power button and the end of the support plate is vertical Extending the connecting plate, the switch board is formed by a vertical extension of the connecting board away from the end of the supporting board, the switch board is switchable between the first position and the second position, and the switch board is partially inserted into the transmitter and received in the first position Between the devices, the switch board is disengaged between the transmitter and the receiver in the second position.

By operating the power button, the electronic device can change the state of the bracket from the state of the photoelectric switch to the state of the photoelectric switch, so that the electronic device can be switched between the closed state and the open state, and the structure is simple and can be effectively used after long-term use, The electronic device will be energized for a long period of time, so that the electronic device has a long service life.

The electronic device of the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

Referring to FIG. 1 to FIG. 4 , the electronic device 30 of the embodiment of the present invention includes a frame 31 , a display screen 32 disposed on the frame 31 , a power button 33 , a printed circuit board 34 , a photoelectric switch 35 , a bracket 36 , and a power source 37 . In this embodiment, the electronic device 30 is an automobile ceiling display, and the photoelectric switch 35 is an infrared photoelectric switch.

The frame 31 includes a substrate 311 on which a corresponding receiving screen 32 is provided with a receiving slot (not shown), and a corresponding receiving button (not shown) is provided for the corresponding power button 33. A mounting portion 3111 (shown in FIG. 2) is formed on a rear surface of the substrate 311 adjacent to the power button 33.

The printed circuit board 34 is fixed to the mounting portion 3111 of the substrate 311, and is electrically connected to the display screen 32 and the power source 37.

The photoelectric switch 35 is electrically connected to the printed circuit board 34, and includes a bottom plate 351 fixedly coupled to the printed circuit board 34, and an emitter 352 and a receiver 353 connected to opposite ends of the bottom plate 351.

The bracket 36 includes a support plate 361 connected to the power button 33, a connecting plate 362 extending perpendicularly from the end of the support plate 361, and a switch plate 363 extending perpendicularly from the end of the connecting plate 362 away from the support plate 361. The switch board 363 is partially inserted between the transmitter 352 of the photoelectric switch 35 and the receiver 353. In the present embodiment, the switch plate 363 includes a main body portion 3631 and an insertion end 3632 extending from the end of the main body portion 3631. The insertion end 3632 has a right-angled trapezoidal shape.

When the electronic device 30 is used, the power button 33 is pressed, and the holder 36 is moved in a direction away from the substrate 311 to cause the switch board 363 to come out of the photoelectric switch 35 (as shown in FIG. 4). At this time, the receiver 353 of the photoelectric switch 35 can receive the light emitted from the emitter 352 and issue an open command to the power source 37 via the printed circuit board 34, thereby turning on the display screen 32. When the electronic device 30 needs to be turned off, it is only necessary to pull back the power button 33 to re-enter the switch board 363 between the transmitter 351 and the receiver 353 of the photoelectric switch 35 (as shown in FIG. 3), since the transmitter 352 emits The light is blocked by the switch board 363, the receiver 353 is unable to receive the emitted light, the photoelectric switch 35 senses that the switch board 363 enters, and issues a close command to the power source 37 via the printed circuit board 34, thereby turning off the display screen 32.

By operating the power button 33, the electronic device 30 can change the state of the bracket 36 from the state of extending into the photoelectric switch 35 to the state of the photoelectric switch 35, so that the electronic device 30 can be switched between the closed state and the open state, and the structure is simple and after long-term use. can The effective use does not cause the electronic device 30 to generate a long-term power supply, so that the electronic device 30 has a long service life.

It can be understood that the printed circuit board 34 can also be connected to other electronic components inside the electronic device 30, such as a speaker or the like, to control the opening and closing of the electronic components by the photoelectric switch 35 and the printed circuit board 34. In addition, a resilient latching structure may be disposed between the bracket 36 and the frame 31, so that after the power button 33 is pressed, the bracket 36 and the frame 31 are locked, that is, the switch board 363 is kept out of the photoelectric switch 35, and the electronic device 30 is turned on; When the power button 33 is pressed again, the bracket 36 and the frame 31 are unlocked, that is, the switch board 363 re-enters the photoelectric switch 35, and the electronic device 30 is turned off.

In summary, the present invention has indeed met the requirements of the invention patent, and has filed a patent application according to law. However, the above is only a preferred embodiment of the present invention, and it is not possible to limit the scope of the patent application in this case.
