Description

The equidistant mechanical type scrambler of single grid

The utility model relates to the equidistant mechanical type scrambler of a kind of single grid, is meant a kind of mechanical type scrambler of resolving runner rotation direction and rotational angle size that improves especially.

Mechanical coding device commonly used at present mainly includes parts such as runner 01, reed 02～04 as shown in Figure 1; As shown in Figure 2, runner 01 front is provided with two grating rings 012,013 and the ring heart 014 from outside to inside, and contacts with reed 02～04 in regular turn; The reed 04 and the power supply of ining succession.When runner 01 rotated, the signal of reed 02, the 03 exportable different change in voltage in the ideal ( waveform 2A, 3A as shown in Figure 3) reached the coding purpose.But following shortcoming is arranged during its actual use: (1) two grating ring 012,013 certain position gap at interval just can be obtained the coding signal, so will cause the signal group number that takies too many space and cause output to reduce.(2) since two reeds 02,03 and distance of shaft centers from different, when runner 01 rotates, reed 02,03 will have different relative moving speeds with runner 01, make the different contact of reed 02,03 output bounce waveform 2B, the 3B of (Bounce) phenomenon; Therefore the spring elimination circuit (Debuoncer) that connects the scrambler output terminal must be adjusted it respectively when producing, very inconvenient; Perhaps can compress the ratio that changes spring waveform and normal waveform, but original not high resolution is more reduced by changing the mode of grating ring size.

Fundamental purpose of the present utility model provides a kind of mechanical type scrambler of resolving runner rotation direction and rotational angle size that improves.

Another purpose of the present utility model provides the spring that a kind of output terminal connects and remove the mechanical type scrambler that circuit can conveniently be adjusted when producing.

The utility model is achieved in that and includes runner, a plurality of reeds, it is characterized in that: wherein the single face of runner is provided with around the runner axle center and is the grating ring of strip, and contacts with each reed; Grating ring is provided with different conducting part of electric conductivity and insulation division, and is equidistant at each reed contact point of grating ring and runner axle center.When runner obtains electric power and rotates, the signal of the exportable different change in voltage of reed, then the level circuit can be judged the rotation direction of runner from the order of signal output, can export the size that number is judged the runner rotational angle by signal, can improve output signal group number, make that the rotation of minute angle is monitored to go out, reach the purpose of high-res.

Wherein the grating ring on the runner also can adopt vertical bar, but with the axle center at angle.

Characteristics of the present utility model are: can reach and improve the effect that can conveniently adjust when resolving runner rotation direction and rotational angle size and production.

Introduce detailed construction of the present utility model, application principle, effect and effect below in conjunction with accompanying drawing.

Figure 10 is that the utility model uses synoptic diagram.

Referring to Fig. 4-Fig. 8, the utility model mainly is made up of members such as runner 1, reed group 4, base 5, one group of clamping plate 6, holders 7, wherein: runner 1 is provided with grating ring 11, the ring heart 12 around the axle center from outside to inside, and wherein grating ring 11 is to be made of the conducting part 111 that has different electric conductivities and be set in distance, insulation division 112.The electric conductivity of conducting part 111 is greater than insulation division 112, and connects an end of rotating shaft 2 in the axle center of runner 1, and the other end of rotating shaft 2 is to connect roller 3, is arranged on the base 5 again.

Two clamping plate 6 are to be fixedly arranged on the holder 7, and the centre has a spacing just can hold runner 1 rotation; On the clamping plate 6 and be provided with reed group 4, three reeds 40,41,42 are arranged among the embodiment of the present utility model, wherein two relative and isometric reeds 41,42 contact two grating rings 11 respectively, 40 contact ring hearts 12 of another reed.

When runner 1 obtains the electric power that is transmitted by reed 40 and rotates, reed 41,42 constantly is contacted with the conducting part 111 or the insulation division 112 of grating ring 11 respectively in regular turn, make the signal of reed 41,42 exportable different change in voltage, the digital signal of reed 41,42 outputs is respectively:

(1) when reed 41,42 all contacts with conducting part 111, exportable (1.1) signals (referring to Fig. 5).

(2) when reed 41 contacts with insulation division 112, when reed 42 contacts with conducting part 111, exportable (0.1) signal (referring to Fig. 6).

(3) when reed 41,42 all contacts with insulation division 112, exportable (0.0) signal (referring to Fig. 7).

(4) contact with conducting part 111 when reed 41, when reed 42 contacts with insulation division 112, exportable (1.0) signals (referring to Fig. 8).

Runner 1 will constantly repeat output signal according to signal 1-2-3-4 order when clockwise rotating among the figure; Again when runner 1 when rotating counterclockwise, will constantly repeat output signal according to signal 4-3-2-1 order.Late-class circuit can be judged the rotation direction of runner 1 in proper order by signal output; Judge by signal output number and the size of runner 1 rotational angle can improve the signal group number of output that the rotation that makes minute angle can be detected and reach the purpose of high-res.

Because signal is to export from two relative and isometric reeds 41,42, so reed 41,42 contact points make the spring that connects the scrambler output terminal remove circuit and adjust easily when producing because of equidistant with runner 1 axle center.

Referring to Figure 10, the utility model can be applicable in the Genius mouse, makes can more accurate differentiation Genius mouse small the moving of computer.Rotating shaft perhaps of the present utility model can or connect the micro-machine rotation with finger rotation, and it is whole etc. that alternative variable potentiometer applies to vertical, horizontal synchronization adjustment on the monitor or the volume of combination audio, high low pitch.
