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.
