Please refer to Fig. 1 ~ Fig. 2; But the notebook computer of the display automatic lifting of the utility model embodiment; Comprise main frame 10, display 20 and be arranged at main frame 10 and display 20 between automatic hoisting mechanism 30, can control automatic hoisting mechanism 30 according to user's needs and make display 20 rise or drop to the height of needs.

Automatic hoisting mechanism 30 comprises power source 31, bracing frame 33, switching-over gear train 35, tooth bar 37 and control module 39.

What power source 31 was embedded at main frame 10 is connected a side with display 20, for having the motor of rotating function.In this embodiment, power source 31 is for having the ultrasound electric machine of rotating and auto-lock function, promptly locks with promptly stopping of realizing that display 20 goes up and down.

What one end of bracing frame 33 was rotationally connected with main frame 10 is connected a side with display 20, but the weight of support displays 20.Wherein, said main frame 10 be connected a side and support frame as described above 33 with display 20 for hollow-core construction or be provided with groove etc., can be used as the passage of main frame 10 and display 20 connection lines or place miscellaneous part.Among the embodiment of the utility model; Bracing frame 33 is one; Be located at main frame 10 and centre positions display 20 junctions, accordingly, power source 31 is single output shaft; Certainly, can also be provided with this list output shaft drive simultaneously two groups or more commutate gear train 35 with about synchronously control the up-down of display 20; In another embodiment; Bracing frame 33 is two; Be located at main frame 10 and two ends display 20 junctions; Accordingly, power source 31 is for being provided with the power source 31 of double output shaft that angle is 180 ° synchronous rotation, can by switching-over gear train 35 with about synchronously control the up-down of display 20.

Switching-over gear train 35 is used for power source 31 outputting powers are converted into the up-down power of display 20, is rotationally connected with power source 31 output terminals, and is provided with lifter wheel 350 at bracing frame 33 other ends.

In a kind of embodiment of the utility model, switching-over gear train 35 comprises: drive link 351, first gear-driven assembly 352 and second gear-driven assembly 353.

Drive link 351 is located on the bracing frame 33 rotationally, for example uses bearing to be fixedly arranged on the bracing frame 33.

First gear-driven assembly 352 is arranged on drive link 351 1 ends and power source 31 output shafts, and particularly, first gear-driven assembly 352 is conical gear group, worm and gear gear set or crossed helical gears group.

Second gear-driven assembly 353 is arranged at the gear and the lifter wheel 350 of drive link 351 other ends and forms; Particularly; Second gear-driven assembly 353 is conical gear group, worm and gear gear set or crossed helical gears group, cooperates with first gear-driven assembly 352 to realize accurate displacement control.Wherein, when adopting the conical gear group, lifter wheel 350 corresponds to the conical gear (as shown in Figure 5) that the other end is provided with the gear 3501 of synchronous rotation, and the gear driven tooth bar 37 of said synchronous rotation goes up and down; When adopting the worm and gear gear set, lifter wheel 350 corresponds to turbine, can directly drive the tooth bar 37 that is provided with the groove that coincide with the turbine dimpled grain.

Tooth bar 37 is fixedly arranged on the display 20, drives to realize the up-down of display 20 with lifter wheel 350 engagements and by lifter wheel 350.

Control module 39 is electrically connected the also corresponding up-down power of control power source 31 outputs, as controls said power source 31 forward rotation display 20 is risen, and controls said power source 31 backward rotation and makes display 20 landing.In this embodiment, control module 39 is a may command power source 31 forwards, counter-rotational entity CS; In another embodiment, control module 39 is a power circuit, and rising with driving display 20 in the source 31 that turns on the power when detecting launch computer, cuts off the power supply automatically when being raised to preset height, and it is then opposite to shut down; In the another embodiment, control module 39 is controlled power source 31 through the form of computer mouse or keyboard operation and is driven the height that displays 20 in time raise or drop to needs for being located at the control module in the notebook computer processing unit.

Please refer to Fig. 3, in a kind of embodiment of the utility model, the centre position of drive link 351 is provided with the clutch structure 354 that drive link 351 is divided into epimere drive link and hypomere drive link, and said clutch 354 comprises right cylinder 3541 and accepting groove 3543.

Right cylinder 3541 coaxial hearts are fixedly arranged on the lower end of said epimere drive link; Accepting groove 3543 coaxial hearts are fixedly arranged on the upper end of said hypomere drive link, the friction force that right cylinder 3541 and the inwall with accepting groove 3543 of respective cylindrical host cavity fit tightly and keep being scheduled to; Wherein, said right cylinder 3541 and said accepting groove 3543 is provided with the position and can exchanges.Said friction force is the power that keeps display 20 normally to go up and down when making operation control unit 39; Since said friction force exist drive link 351 not stuck with corresponding first gear-driven assembly 352 and second gear-driven assembly 353; When display 20 goes up and down to be obstructed; Promptly rise to the top or reduce to bottom limit can not rise again or fall the time; Power source 31, first gear-driven assembly 352 and hypomere drive link overcome said friction force and are rotated further, and epimere drive link, second gear-driven assembly 353 stop operating, and display 20 is lifting moving no longer; So prevent automatic hoisting mechanism 30 parts damages, increased the notebook computer safety in utilization.

Please refer to Fig. 4, in the another kind of embodiment of the utility model, switching-over gear train 35 comprises first transmission gear 355, second transmission gear 356 and driving-belt 357.

First transmission gear 355 is arranged at power source 31 output shafts.

Second transmission gear 356 is arranged at the end that bracing frame 33 is connected with main frame 10, is provided with groove with 355 engagements of first transmission gear and an end.Accordingly, lifter wheel 350 1 ends are provided with and corresponding another the consistent groove of said groove.

Driving-belt 357 hang on two grooves, is used for power transmission to the second transmission gear 356 with first transmission gear 355.Wherein, first transmission gear 355 and second transmission gear 356 constitute conical gear group, worm and gear gear set or crossed helical gears group.

But the process of manipulating of the notebook computer of display 20 automatic lifting of the utility model embodiment is: at first open notebook computer, operation control unit 39 is connected ascent direction power supplys input power sources 31, will rise power by bracing frame 33 and switching-over gear train 35 and reach lifter wheel 350; Lifter wheel 350 drives the tooth bar 37 that is fixedly arranged on the display 20 so that display 20 rises; When display 20 to rising to ideal height, operation control unit 39 is cut off the electricity supply again, because power source 31 is for having the ultrasound electric machine of auto-lock function; Add the rotary resistance of switching-over gear train 35 self; Display 20 can not rise again and can not descend yet, and can rest on this height, descends display 20 if want; Need only get final product by the operation control unit 39 reverse power supplys that insert, simple to operation.

To sum up, the notebook computer of the utility model embodiment can realize that a key control display 20 automatic lifting to the height that needs, greatly satisfy people to the convenience of laptop computer displays 20 descending operations, the operational requirements of agility.

The above is the embodiment of the utility model; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; Can also make some improvement and retouching, these improvement and retouching also are regarded as the protection domain of the utility model.
