Embodiment
With reference to shown in Figure 1, the utility model proposes a kind of roller structure 100 that is applicable to portable electron device, comprise that rolling ring 110, tested element 120 and two are near switch 132,134.Wherein rolling ring 110 can be located on the portable electron device, and can be around an axis clockwise or be rotated counterclockwise.Tested element 120 is attached at the inner ring of rolling ring 110, when rolling ring 110 rotations, and the rotation thereupon of tested element 120, thereby the sense of rotation and the speed of indication rolling ring 110.
Be located at rolling ring 110 inside near switch 132,134 for two, have a differential seat angle a between the two.Two can detect moving of tested element 120 near switch 132,134.For instance, when tested element 120 near near switch 132 time, switch 132 can output one first pulse signal CHA, when tested element 120 turns over angle a and near near switch 134 time, switch 134 can output one second pulse signal CHB.Have a phase differential between the first pulse signal CHA and the second pulse signal CHB.Just can know the speed of tested element 120 (thereby rolling ring 110) by the cycle of calculating the first pulse signal CHA, perhaps also can calculate the speed of tested element 120 according to the phase place extent; Moreover, just can know the sense of rotation of tested element 120 by calculating phase differential between the first pulse signal CHA and the second pulse signal CHB.
Have much and can realize above-mentioned function near switch, for instance, tested element 120 can be a magnet, and can be Hall switch near switch 132,134.When magnet shifts near Hall switch, Hall element on the switch detection faces changes the switch internal circuit status because of producing Hall effect, near the object that is magnetic the identification thus exists, and then the on-off of gauge tap, to produce above-mentioned pulse signal CHA, CHB.
Again for example, tested element 120 can be a light-emitting component, near switch the 132, the 134th, optoelectronic switch.When light-emitting component during near optoelectronic switch, optoelectronic switch receives output above-mentioned pulse signal CHA, CHB behind the light.
Fig. 2 is the structured flowchart near switch of an embodiment of the utility model.This comprises movable sensor 201, signal processing circuit 202 and output buffer 203 near switch, after wherein movable sensor 201 detected signals are handled (as shaping) through signal processing circuit 202, can be through output buffer 203 output pulse signal CHA, CHB.
The waveform of the first pulse signal CHA and the second pulse signal CHB as shown in Figure 3, its cycle is roughly the same, but differ a phase, this phase is relevant near the differential seat angle a between the switch 132,134 with two.
These first pulse signal CHA and the second pulse signal CHB be through the conversion of portable electronic equipment internal hardware structure and operating system, just can become be similar on the PC be used for scrolling move up and down operation and move left and right is operated.
Fig. 4 is the portable electron device with roller structure of the present utility model.With reference to shown in Figure 4, portable electron device 400 its pivots 430 that have one first housing 410, second housing 420 and connect first housing 410, second housing 420.In one embodiment, roller structure 100 is arranged on the pivot 430 of electronic installation 400, and wherein rolling ring is to be provided with around pivot 430.Therefore roller structure does not take additional space.
Yet in a not shown embodiment, roller structure also can be arranged on the surface of portable electron device, and wherein rolling ring is to protrude from this surface, so that operated by the user.
What deserves to be mentioned is that electronic installation 400 includes but not limited to mobile phone, personal digital assistant.
In addition, get back to shown in Figure 1ly, this portable electron device 400 also comprises a circuit board 440, and it connects near switch 132,134.Circuit board 440 can calculate the sense of rotation and the speed of rolling ring 110 according to the first pulse signal CHA shown in Figure 3 and the second pulse signal CHB, and is converted into the direction and the speed of the required move operation of portable electron device.This move operation can be the move left and right operation, also can be to move up and down operation.
As shown in Figure 4, preferably, be that two roller structures 100 are set on the pivot 440 of portable electron device 400, the output signal of one of them roller structure is corresponding to the move left and right operation of portable electron device, and the output signal of another roller structure is corresponding to moving up and down operation.Scrolling about so being user-friendly for or up and down.
Though the utility model discloses as above with preferred embodiment; right its is not in order to limit the utility model; any those skilled in the art; in not breaking away from spirit and scope of the present utility model; when doing a little modification and perfect, therefore protection domain of the present utility model is worked as with being as the criterion that claims were defined.
