Five, embodiment

(1) the hardware configuration form of roll shaft turn-knob device and various way of realization thereof:

The roll shaft knob basic structure and the principle of work of 1 compressed spring type sensor:

1.1 as shown in Figure 1, mainly contain following part in its basic structure: right side fine motion thin film switch (being fixed on above the circuit board 4) 1, middle fine motion thin film switch (being fixed on above the circuit board 4) 2, left side fine motion thin film switch (being fixed on above the circuit board 4)

3, circuit board 4, flexible keystroke plate (with other button one) 5, button transmission plate 6, bearing 7, roll shaft knob 8 (comprising a 8-1), the elastic spring 9 that produces feel, reed fixator 10, daisy wheel rotor 11, fixing metal spring leaf 12 and 14 also have corresponding with 12 and 14 respectively live metal reed 13 and 15.

1.2 when 8 rotations of roll shaft knob, the daisy wheel rotor 11 coaxial with it rotates simultaneously, drives live metal reed 13 and 15 and moves up and down, and constantly connects one with corresponding fixing metal reed 12 and 14 respectively and separates.Suitably adjust the relative position of these four reeds, make the phase differential that has on its sequential of connecting-separating about 90 degree, so just produced as shown in figure 13 pulse sequence figure.The difference of the pulse sequence that produces during the rotating of roll shaft knob can identify rotational angle and direction thereof easily by the processor in the electronic equipment..

1.3 bearing 7 provides bearing for roll shaft 8, elastic spring 9 and metal spring leaf 12,13,14,15.Corresponding roll shaft knob is realized switch motions by devices such as transmission levers to two or three keys touchings among the horizontal roll shaft knob structure of the present invention figure.。

1.4 the protruding part of elastic spring 9 is pressed in the periphery with daisy wheel rotor 11, when daisy wheel rotor 11 rotation, produces the calibration feel, and the electrical pulse sequence that sends with metal spring leaf is synchronous.

1.5 flexible keystroke plate 5 can with other button on the hand-hold electronic equipments (for example for mobile phone; usually also have number of digital key etc.) one; constitute a complete keypad; and has suitable flexibility; can adapt to roll shaft and press the distortion of film microswitch 1,2 and downwards at 3 o'clock; also produce certain elasticity, button is resetted, can also play the location to whole roll shaft knob simultaneously.

1.6 button transmission plate 6 sticks into one with flexible keystroke plate 5, actuation of keys is delivered on the corresponding film microswitch (1 or 2 or 3), the film microswitch is switched on or switched off, four thrusts of its below also play two vital role simultaneously: the one, isolate the button effect, prevent the situation that a plurality of microswitches are pressed simultaneously: the 2nd, actuation of keys is played position-limiting action, the damage that may cause the film microswitch when avoiding button overweight.Its principle of work is as follows: when pressing the middle part of lower roller shaft 8., bearing 7 moves down, two thrusts prop up wiring board 4 downwards in the middle of button transmission plate 6, microswitch 2 is switched on, simultaneously the switch of both sides is subjected to the restriction of these two thrusts in the middle of the button transmission plate 6, can not be pushed and connects (see figure 4).And when pressing the right of lower roller shaft 8, the right side of bearing 7 moves down, two thrusts prop up wiring board downwards until button transmission plate 6 the right, microswitch 1 is switched on, simultaneously button transmission plate 6 left sides and middle part are lifted, and make film microswitch 2 and 3 can not be pushed and connect (seeing Fig. 5-1).The principle of logical sample also is suitable for the film microswitch 3 with the left side.

1.7, connect switch 1 or switch 3 when pushing left button or right button respectively for two-key type roll shaft knob.Similar to triple bond roll shaft knob, three thrusts of button transmission plate 6 belows play two vital role equally: the one, isolate the button effect, and prevent the situation that a plurality of microswitches are pressed simultaneously; The 2nd, actuation of keys is played position-limiting action, the damage that may cause the film microswitch when avoiding button overweight (seeing Fig. 3-2 and Fig. 5-2).

Other way of realization of the rotation sensor of 2 roll shaft knobs:

2.1 piezoelectric transducer:

Adopt piezoelectric sensor, to rotate the vibration that produces and pass to piezoelectric sensor 16 with being pressed in the flexible member of daisy wheel rotor surface on concavo-convex, relevant with the anglec of rotation and direction and the electric impulse signal that have an appointment 90 degree phase differential of generation, pass to processor processing, thereby obtain detection for rotation.Its structure is seen Fig. 6.The electric signal that sensor produces is input to processor and gets final product after amplifying also shaping by voltage amplifier or charge amplifier.

2.2 magnetic sensor:

A kind of scheme (as Fig. 7) is to stick the magnetic pole 17 of (or in record) N-S checker at daisy wheel rotor surface circumference place, when disk rotates, in the magnetic field of checker, produce the electric signal of the checker of about 90 degree of phase differential near two Hall elements 18,19 of magnetic pole.

Another kind of scheme (as Fig. 8) is to adopt the daisy wheel rotor of metal, and Hall element 18,19 is combined into a detection components with minitype permanent-magnet 20,21 respectively.When disk rotates, in the magnetic field of checker, produce the electric signal of the checker of about 90 degree of phase differential near two Hall detection components of disk.

After the electric signal amplification and shaping with the Hall element generation, become the electrical pulse sequence that has about 90 degree phase differential, pass to processor processing, thereby obtain for the detection of rotating.

This programme is meaningful especially for the roll shaft knob of realizing waterproof construction.

2.3 optical sensor:

A kind of scheme (as Fig. 9) is to leave equally distributed light hole at daisy wheel rotor or rotating circular disk surface near the periphery, rotor one side is installed light-emitting component 24 and 25 (such as light emitting diode), and an other side is installed two photo-sensitive cells 22 and 23 that mate with light-emitting component.When disk rotates, photo-sensitive cell detects the light signal of checker, produce the electric signal of checker, through becoming the electrical pulse sequence that has about 90 degree phase differential after amplification, the shaping, being input to processor gets final product, another kind of scheme (as Figure 10) is that the light hole that will open originally in daisy wheel rotor or disc surfaces moves on to a cage shape surface that extends out, cage installed inside light-emitting component 24 and 25 (such as light emitting diodes), the outside are installed two photo-sensitive cells 22 and 23 that mate with light-emitting component.Other the scheme with Fig. 9 is identical.

This programme is also meaningful especially for the roll shaft knob of realizing waterproof construction.

2.4 electric brush type sensor:

On daisy wheel rotor 11, install and its electrode 26 (as Figure 11) that rotates synchronously.When roll shaft rotates, public brush 27 is conducting with electrode 26 all the time, other two brushes 28 and 29 are then constantly connected one with electrode 26 and are disconnected, so just can on brush 28 and 29, produce periodically variable pulse train, suitably adjust the position between the brush 28 and 29, can generation relevant with the anglec of rotation and the direction electrical pulse sequence that has about 90 degree phase differential is passed to processor processing, thereby obtains the detection for rotation.

The different ways of realization of 3 calibration feels:

Except producing the calibration feel (as Fig. 1-2) with stage clip, can also produce the calibration feel with contactless method, shown in Figure 12 is exactly one of scheme.The interaction of permanent magnet 30 and the chrysanthemum shape rotor it " petal " of metal, utilize " petal " to trend towards that automatically magnetic circuit is closed and characteristic, produce the calibration feel.

Several different ways of realization of 4 buttons:

4.1 common microswitch: as shown in figure 14, common microswitch can be installed very convenient directly on the welding wiring board.

4.2 film microswitch: as shown in figure 15, the film microswitch can be made of one (promptly independently switching motherboard) with other keyswitch, installs as required, also can be directly on the welding wiring board, install also very conveniently, and have good dustproof effect.

4.3 conductive rubber keyswitch: the structure of conductive rubber keyswitch as shown in figure 16, by direct printing in the circuit board electrode and the conductive rubber of button bottom constitute, when pushing button, conductive rubber is connected electrode.All buttons can be made of one (promptly independently keypad) usually.

The interface circuit and the system principle thereof of 5 roll shaft turn-knob devices:

The basic structural principle of electronic circuit that matches with the roll shaft knob as shown in figure 17.The various signals that processor reception rotation sensor and button send, and be correspondingly processed, then result is outputed to display or other output unit, show or indicate the guidance information of result and next step operation/selection.The structure of the circuit structure diagram of two buttons is Figure 17 roughly the same, has just lacked a button.

Figure 18 is a kind of control and the circuit structure principle of display separation formula, is that with basic structure difference shown in Figure 17 its demonstration separates with control, has increased interface module for this reason.Interface can be wired connection (as interfaces such as RS-232, USB), also can be (as interfaces such as common radio, bluetooth, infrared, ultrasound waves) of wireless connections.

Any action of button (press, unclamp) all can cause corresponding potential change, rotation sensor then will rotatablely move and change shown in Figure 13 two tunnel time sequential pulse signals (and the corresponding signal unit of lattice of feel) that 90 degree phase differential are arranged approximately into, these potential change and pulse sequence signal are sent to the processor input port, judge the anglec of rotation of actuation of keys and knob and direction etc. by processor according to interrupt response disposal route or polling method (Figure 19, Figure 20), and handle accordingly.

Also two road pulse sequence signals shown in Figure 13 can be segmented sensing in advance, be sent to the add subtract counter counting again, be sent to the processor input port then and carry out respective handling, to alleviate the burden of processor.

6 response and control principle flow processs for knob rotation and actuation of keys:

Hardware system can adopt the interrupt response form for the response of rotation of roll shaft knob and actuation of keys, also can adopt the form of poll.

What Figure 19 represented is the program circuit principle that adopts the interrupt response form.Hardware system for the form processing of adopting interrupt response, the interface that processor connects input media will have the down trigger function, any potential change (or pulse) that any action of button (press, unclamp) and rotation sensor or counter send all can cause interruption, triggering corresponding interrupt handling routine handles, and result outputed to display or other output unit, show or the guidance information of indication result and next step operation/selection.

The handling procedure flow process of the employing poll processing form that Figure 20 represents.Polling mode does not require that interface has interrupt function.The Interface status of system's timing (for example 3-10 millisecond) scanning button and knob, and be kept at Interface status original in the storer relatively, discovery changes and judges at once and make respective handling, then result is outputed to display or other output unit, show or indicate the guidance information of result and next step operation/selection, and preserve current Interface status with standby.
