For the present invention aforementioned and other technology contents, feature and effect, in following cooperation refer to the attached drawing is preferableIn the detailed description of embodiment, can clearly present.The direction term being previously mentioned in following examples, for example：Upper and lower, left,It is right, front or rear etc., only it is the direction with reference to attached drawings.Therefore, the direction term for using is for illustrating not for limitingThe present invention.
Fig. 1 is referred to, the portable electron device 100 of the present embodiment can be a tablet PC, and it is mainly wrappedA body 110, one first Magnet 120, an additional mechanism providing additional operation 130, a controller 140, an electric magnet 150, an acceleration sense are includedSurvey the power supply 170 of device 160 and.
Body 110 can have a guidance panel（Do not show）.
As shown in Figure 1, Figure 2 and Figure 3, the first Magnet 120 is arranged among body 110.
Additional mechanism providing additional operation 130 is connected in a detachable fashion body 110, and additional mechanism providing additional operation 130 has one second Magnet132.Here, the second Magnet 132 corresponds to the first Magnet 120, and the second Magnet 132 can attract each other with the first Magnet 120.In other words, additional mechanism providing additional operation 130 is with separable by the interattraction between the first Magnet 120 and the second Magnet 132Mode is connected to body 110.Additionally, in the present embodiment, additional mechanism providing additional operation 130 can be a protection cap or a keyboard.When additionalWhen mechanism 130 is a protection cap, it can protect the guidance panel of body 110 not damaged by scratch；And working as additional mechanism providing additional operation 130 isDuring one keyboard, it can provide a user and carry out the function of information input.
As shown in figure 1, controller 140 is arranged among body 110.
Electric magnet 150 is arranged among body 110, and electric magnet 150 is electrically connected at controller 140.Here, electromagnetismSecond Magnet 132 of the ferrum 150 corresponding to additional mechanism providing additional operation 130.
As shown in Figure 1, Figure 2 and Figure 3, acceleration sensor 160 is arranged among body 110, and acceleration sensor160 are electrically connected at controller 140.In the present embodiment, acceleration sensor 160 can add a gyroscope with a gravityThe device that fast device is combined.
As shown in figure 1, power supply 170 is arranged among body 110, and power supply 170 is electrically connected at controller 140.This, it is electric that controller 140 can optionally order about the supply one of power supply 170 according to a sensitive information of acceleration sensor 160Flow to electric magnet 150, with force electric magnet 150 to attract or repulsion additional mechanism providing additional operation 130 the second Magnet 132.
Next the function mode of portable electron device 100 is illustrated.
First, in the case where body 110 and additional mechanism providing additional operation 130 are combined together, when portable electron device 100 is inDuring vertically position as shown in Figure 3, additional mechanism providing additional operation 130 can be easy to depart from body 110 because of action of gravity.Now, when justThe adhesion being more than with joint efforts between body 110 and additional mechanism providing additional operation 130 of the inertia force and gravity suffered by portable electronic apparatus 100（That is, the magnetic attraction between the first Magnet 120 and the second Magnet 132）When, additional mechanism providing additional operation 130 will depart from body 110.
However, in order to prevent additional mechanism providing additional operation 130 from undeservedly departing from body 110, when acceleration sensor 160 sense it is portableThe adhesion being more than with joint efforts between body 110 and additional mechanism providing additional operation 130 of the inertia force and gravity suffered by formula electronic installation 100When, acceleration sensor 160 can export a corresponding sensitive information to controller 140, and controller 140 will order about power supply170 supplies one（It is positive）Electric current to electric magnet 150, to force electric magnet 150 to attract the second Magnet 132 of additional mechanism providing additional operation 130.ThisWhen, by extra magnetic attraction produced between the Magnet 132 of electric magnet 150 and second plus body 110 and additional mechanism providing additional operation 130 itBetween magnetic attraction making a concerted effort more than the inertia force suffered by portable electron device 100 and gravity, you can be prevented effectively from additional machineStructure 130 departs from body 110.Conversely, when acceleration sensor 160 senses the inertia force suffered by portable electron device 100With gravity with joint efforts less than the adhesion between body 110 and additional mechanism providing additional operation 130 when, this represents additional mechanism providing additional operation 130 and does not take offFrom the probability of body 110.Now, controller 140 will not order about power supply 170 and supply any electric current to electric magnet 150, and electromagnetismFerrum 150 will not produce any magnetic force.
On the other hand, no matter portable electron device 100 is under which kind of storing state, in order to promote additional mechanism providing additional operation130 depart from body 110, and portable electron device 100 can also receive the input instruction of a user and go to allow controller 140 to order about electricityThe supply of source 170 one（Reversely）Electric current to electric magnet 150, to force the second Magnet 132 of the repulsion additional mechanism providing additional operation 130 of electric magnet 150.In other words, the magnetic force produced by electric magnet 150 can repel each other with the magnetic force of the second Magnet 132, thus additional mechanism providing additional operation 130 can be aided in suitableProfit departs from body 110.
