The principles of the present invention are described as follows below:
Liquid crystal display is from the state of closing to the process dug: firstly, powering on, clicking control button (OPEN)；Then line
Road plate receives signal and issues instruction, at this time electrical power, and motor rotation driven gear rotation, wheel and rack is meshed, tooth
Item moves horizontally forward, and rack gear is mounted on the first guide rail, and the first guide rail travels forward under the guiding of first sliding groove；Rack gear to
Push-pull rod rotation is driven while preceding movement, the rotation of push-pull rod drives liquid crystal display rotation by hinged-support, and shielding fulcrum then can be with
The rotation of liquid crystal display and rotate, when liquid crystal display rotates, pushing piece to swing forward will push the second guide rail and travels forward, and second leads
Rail travels forward under the guiding of second sliding slot, and while the second guide rail travels forward, the upper surface of the second guide rail pushes bearing
It moves upwards, third guide rail moves upwards under the guiding of third sliding slot, and it is concordant with panel that supporting plate slowly rises to highest point；When
The first recovery spring and the second recovery spring stress are in tensioned state when supporting plate rises to highest point；And supporting plate reaches highest point
When, the locating plate being connected on rack gear touches the position-sensing switch of front, and wiring board receives to instruct and issue signal, and motor stops turning
Dynamic, liquid crystal display stops overturning, and liquid crystal display is powered.
Liquid crystal display is from tip-up state to the process closed: pressing control button (CLOSE key), it is concurrent that wiring board receives signal
It instructs out, whether mouse infrared inductor starting, detection mouse playbacks, if mouse is not put mouse box into or is not put well,
Then wiring board sending is ticked sound, and motor does not work, and until mouse normally playbacks, then presses control button (CLOSE again again
Key)；At this point, electrical power, the rotation of motor rotation driven gear, rack gear horizontal rearward movement lead to while rack gear moves backward
Crossing push-pull rod drives liquid crystal display slowly to close, and screen fulcrum can be rotated with liquid crystal display, and the rotation of liquid crystal display pushes piece backward simultaneously
Rotation, the pressure for pushing piece to be applied on the second guide rail at this time are slowly reduced, and the second guide rail is under the action of first restores spring
It moves backward, third guide rail moves downward under the action of second restores spring, until supporting plate drops to minimum point, pushes piece
It is detached from the second guide rail, the second guide rail and third guide rail stop motion.It is now placed in rack gear front end finger starter and enters photoelectricity
Optocoupler, photoelectricity optocoupler can trigger wiring board, and wiring board issues instruction, the starting of infrared emission inductor, and finger function comes into force, this
If when someone hand when not leaving keyboard, infrared emission inductor can detect, liquid crystal display is become to dig shape by the state of closing
State prevents hand clamping, until the hand of people leaves keyboard and presses again control button (CLOSE key), liquid crystal display continues to be turned to
When concordant with panel, the locating plate on rack gear can touch the position-sensing switch of back, and wiring board receives to instruct and issues signal, motor
Power-off, liquid crystal display stop operating, and liquid crystal display closing finishes.
Above-described embodiment is the preferable embodiment of the utility model, but the embodiments of the present invention is not by above-mentioned
The limitation of embodiment, it is made under other any spiritual essence and principles without departing from the utility model to change, modify, replacing
In generation, simplifies combination, should be equivalent substitute mode, is included within the protection scope of the utility model.
