As shown in Figure 3, said execution module also comprises damping flexible glue 6, and said damping flexible glue 6 is between first end and electromagnet 1 of lever 2.Damping flexible glue 6 can reduce lever 2 and attracted and discharge the vibrations of generation when switching by electromagnet 1, and can limit the stroke of lever 2, and the size and the variation range of regulating resistance played a very important role.
As shown in Figure 2, said perception control module is a microswitch 10.The direct supply of microswitch 10 1 termination notebook computers, another termination electromagnet 1.Microswitch 10 needs to bear the working current of electromagnet 1, if can not, then available relay or triode etc. expand stream.Can be as required at screen edge a plurality of switches that distribute.When the microswitch at staff contact screen edge and when making it closure, the notebook direct supply can be supplied power to electromagnet, and electromagnet gets and will drive the controllable resistance rotating shaft after electric, makes it resistance and reduces; After staff left, microswitch broke off, the electromagnet dead electricity, and the controllable resistance rotating shaft resets under spring action, and resistance increases.
The principle of work of present embodiment further describes as follows: when needs reduce the rotating shaft resistance, and the closed microswitch 10 of user.Electromagnet 1 energising, lever 2 is by electromagnetic attracting force, and this strength is through the transmission and the amplification of lever 2 effects; Overcome the thrust of spring 4; The suffered thrust of a core 52 (among the figure to the right) is reduced, so the pressure of axle core 52 and the inwall of axle sleeve 51 reduces, the rotational resistance of rotating shaft also reduces.When needs strengthened the notebook computer rotation shaft resistance, the user broke off microswitch 10.Electromagnet 1 no power, first end of lever 2 is released, and under the effect of spring 4, the axle core 52 of taper is compressed to the right, with the axle sleeve 51 inwall contact forces increase of rotating shaft, so the rotational resistance of rotating shaft also strengthens.

If the user hopes that screen is easier to rotate, the perception control module can be broken off every phase winding of stepper motor, and at this moment, resistance is minimum during the stepper motor passive rotation, so resistance is minimum during the screen passive rotation.Rotating shaft is tighter if the user hopes screen; In can be through of every phase winding short circuit of perception control module with stepper motor; At this moment, resistance increases during the stepper motor passive rotation, so resistance increases during the screen passive rotation; If resistance is still not enough, can a phase winding of stepper motor be passed to constant DC stream to increase stiction
Engaged wheel 82 can change the rubber wheel into screen axle core 52 gears, thus vibrations and noise when reducing stepper motor and rotating.Can strengthen the driving moment of stepper motor through gear shift, reduce the power and the volume of stepper motor.
Embodiment 4
As shown in Figure 6; Present embodiment is with the different of the foregoing description: said perception control module comprises perception unit and control module; Said control module is connected between perception unit and the execution module, and said perception unit detects to be sent to behind the signal of user's rotating screen and sends the adjustment resistance signal to execution module after control module, said control module are received the signal of user's rotating screen.
The example of some perception unit of giving an example below describes:
Said perception unit can comprise the touch sensible electrode.The touch sensible electrode can be arranged in screen edge.At this moment, human body can be counted as induction antenna.When human body contacted uninsulated touch sensible electrode, the electromagnetic wave signal human body low frequency or high frequency that the touch sensible electrode pair is sensed amplified, handles, thereby obtained human body touch signal (promptly turning the resistance of the rotating shaft of notebook computer down).
Said perception unit can comprise conductive electrode.Positive and negative conductive electrode distance is suitably arranged.At this moment, utilize the electric conductivity of human body.When human body contacted positive and negative electrode simultaneously, conductive electrode identified change in current, thereby obtained human body touch signal (promptly turning the resistance of the rotating shaft of notebook computer down).
Said perception unit can comprise pyroelectric infrared sensor.The ultrared motion change of pyroelectric infrared sensor human body radiation.Present thermal release electric infra-red ray moving object induction pick-up can be regulated distance of reaction flexibly, and distance of reaction is adjusted to very little distance, just can be used for the signal of resistance of the rotating shaft of turning notebook computer down that the perception user sends.
Said perception unit can comprise the infrared head and receive head.Also can be divided into infrared ray barrier type and infrared reflection type in such cases.For the infrared ray barrier type; Can with the infrared head with receive placed apart in the both sides that need surveyed area (for example: the coboundary two ends of screen); When this zone of human body contact, the light circuit stopped, thereby identifies the signal of the resistance of the rotating shaft of turning notebook computer down.For the infrared reflection type, can be with human body as ultrared reverberation, through regulating distance of reaction, also can detect in-plant human body near or touch, i.e. perception goes out the signal of the resistance of the rotating shaft of turning notebook computer down that the user sends.
Said perception unit can comprise touch-screen.The user contacts behind the touch-screen signal of resistance of the rotating shaft of the adjustment that can perception goes out the user and send (comprise transfer big with turn down) notebook computer.
Said perception unit can comprise button.Can use film key or capacitance touch induced key this moment.Signal when the resistance of the rotating shaft that can perception by user contact or when leaving goes out the adjustment that the user sends (comprise turn down and transfer big) notebook computer.
