In addition, some embodiments according to the present utility model, x layers of magnet ring 10 can be composed of x separated magnet rings 10, As shown in Figure 2 b.Alternatively, x layers of magnet ring 10 can also be integrally formed setting, and same magnetic pole is in the x layers of predetermined angle that staggers successively, with Exemplified by upper and lower two layers of magnet assembly, the lower floor of same magnetic pole staggers predetermined angle relative to upper strata, as shown in Figure 2 c.

Further, one embodiment according to the present utility model, as shown in Fig. 2-13, multiple N on every layer of magnet ring 10 Magnetic pole and/or multiple S magnetic poles are set in a manner of wide.That is, when being distributed multiple N magnetic poles and more in the detection faces of magnet ring 10 During a S magnetic poles, the width all same of the width all same of each N magnetic poles and each S magnetic poles；Or the detection faces when magnet ring 10 On when being spaced apart multiple N magnetic poles, the width all same of each N magnetic poles；It is or more when being spaced apart in the detection faces of magnet ring 10 During a S magnetic poles, the width all same of each S magnetic poles.

It should be noted that the width of N magnetic poles and/or S magnetic poles is more narrow better on the premise of magnetic field intensity is ensured, such as It can accomplish 1-2 millimeters, magnetic field intensity is required depending on the hall sensing parameter according to Hall detection components 20.

Specifically, when on magnet ring 10 interval be full of N magnetic poles and the first white space (or S magnetic poles and second white space) When, the magnetic regions angle of N magnetic poles or S magnetic poles can be set according to formula λ=(π+arcsin (X/A)+arcsin (Y/A))/p, Wherein, λ is the magnetic regions angle of N magnetic poles or S magnetic poles, and A is the maximum flux density of N magnetic poles or S magnetic poles, and X is Hall detection components Operating point, Y be Hall detection components point of release, D is length of the magnet ring 10 along the moving direction of moving component, and p is N magnetic The logarithm or the logarithm of S magnetic poles and the second white space of the number of pole or S magnetic poles, that is, N magnetic poles and the first white space, accordingly Ground, the regional perspective d2 of white space can be set according to formula θ=2 π/p-λ.In addition, one according to the present utility model specific Example, the angle in magnetic regions, that is, N magnetic pole magnetics region and the angle of the first white space also can approximately equal, or magnetic area The angle in domain, that is, S magnetic pole magnetics region also can approximately equal with the angle of the second white space.

In addition, it is to be understood that the number of N magnetic poles and/or S magnetic poles is related to the size of magnet ring 10, the ruler of magnet ring 10 Very little bigger, the total number of magnetic pole is more, and detection sensitivity is higher.

One embodiment according to the present utility model, x Hall detection components 20 can match the magnetic of the magnetic pole on magnet ring 10 Property set.For example, when interval is full of N magnetic poles and S magnetic poles in the detection faces of magnet ring 10, x Hall detection components 20 can be double Polar form Hall element, ambipolar Hall element can be respectively induced N magnetic poles and S magnetic poles, to be generated when sensing different magnetic poles Different signals；And for example, when interval is full of N magnetic poles and the first white space in the detection faces of magnet ring 10 or interval is full of S magnetic When pole and the second white space, x Hall detection components 20 can be monopole type Hall element, and monopole type Hall element can sense The magnetic pole matched somebody with somebody, to generate inductive signal when sensing matched magnetic pole, that is to say, that the type selecting and monopole of monopole type Hall element Magnet ring coordinates, if monopole magnet ring is N polar forms, monopole type Hall also selects N polar forms, single if monopole magnet ring is S polar forms Polar form Hall also selects S polar forms.

One embodiment according to the present utility model, each Hall detection components 20 can give birth to according to the magnetic pole type sensed Into corresponding inductive signal.

For example, when being distributed multiple N magnetic poles and multiple S magnetic poles on every layer of magnet ring 10, corresponding Hall detection components 20 exist The first level is generated during face N magnetic poles, and second electrical level is generated in face S magnetic poles., wherein it is desired to explanation, the first electricity It is flat to be high level and second electrical level can be low level, or the first level can be low level and second electrical level can be high level, Level state can specifically be determined according to the type of Hall detection components 20.

In this way, when N magnetic poles on every layer of magnet ring 10 and S magnetic poles are alternately across corresponding Hall detection components 20, accordingly Hall detection components 20 will export stable low and high level pulse train, and thus, the x roads that x Hall detection components 20 export are high The cycle of low level pulse sequence fixes and identical, duty cycle 50%.

And for example, when being spaced apart multiple N magnetic poles on every layer of magnet ring 10, corresponding Hall detection components 20 are in face N magnetic The first level is generated during pole, and second electrical level is generated in the first white space of face.In this way, when N magnetic poles on every layer of magnet ring 10 During with the first white space alternately across corresponding Hall detection components 20, corresponding Hall detection components 20 will export stabilization Low and high level pulse train, thus, the cycle for the x roads low and high level pulse train that x Hall detection components 20 export fix and Identical, duty cycle 50%.

For another example, when being spaced apart multiple S magnetic poles on every layer of magnet ring 10, corresponding Hall detection components 20 are in face S magnetic The first level is generated during pole, and second electrical level is generated in the second white space of face.In this way, when S magnetic poles on every layer of magnet ring 10 During with the second white space alternately across corresponding Hall detection components 20, corresponding Hall detection components 20 will export stabilization Low and high level pulse train, thus, the cycle for the x roads low and high level pulse train that x Hall detection components 20 export fix and Identical, duty cycle 50%.

Thus, the N magnetic poles on magnet ring 10 and/or S magnetic poles can be accomplished very intensive (magnet pole widths can accomplish 1-2mm), spirit Sensitivity is high, can improve the frequency of feedback pulse, so as to shorten detection time, improve detection sensitivity.Moreover, based on suddenly That effect, it is reliable and stable, low, impulse waveform stabilization is disturbed, low and high level saltus step is rapid.

One embodiment according to the present utility model, predetermined angle include the first predetermined angle, the second predetermined angle and the Three predetermined angles, when being distributed multiple N magnetic poles and multiple S magnetic poles in the detection faces of every layer of magnet ring 10, x layer magnet ring 10 is according to N The sum of the number of magnetic pole and S magnetic poles the 3rd predetermined angle that staggers；When being distributed multiple N magnetic poles on every layer of magnet ring 10, x layer magnet ring 10 stagger the first predetermined angle according to the sum of number of N magnetic poles and the first white space；When being distributed multiple S magnetic on every layer of magnet ring 10 During pole, x layer magnet ring 10 staggers the second predetermined angle according to the sum of number of S magnetic poles and the second white space.

That is, x layers of magnet ring 10 can stagger arrangement distribution, and x layers of magnet ring 10 number of magnetic poles that can match magnet ring 10 stagger it is default Angle, the preset phase angle so that the x road feels induction signal that x Hall detection components 20 export respectively staggers successively, so that, carry at double Rise detection sensitivity.

As shown in Fig. 2-13, by taking two layers of magnet ring 10 as an example, upper strata magnet ring 10A uses identical row with lower floor magnet ring 10B Stagger predetermined angle between the same magnetic magnetic pole of mode for cloth, upper strata magnet ring 10A and lower floor magnet ring 10B, that is to say, that as schemed Shown in 2b-2c, Fig. 3, Fig. 8 a-8b and Fig. 9, each N magnetic poles of lower floor (or internal layer) magnet ring 10B are relative to upper strata (or outer layer) The corresponding N magnetic poles of magnet ring 10A stagger predetermined angle, and each S magnetic poles of lower floor (or internal layer) magnet ring 10B are relative to upper strata magnetic The corresponding S magnetic poles of ring 10A stagger predetermined angle.As shown in Fig. 4 b-4c, Fig. 5 and Figure 10 a-10b, Figure 11, lower floor (or it is outer Layer) each N magnetic poles of magnet ring 10B stagger predetermined angle relative to the corresponding N magnetic poles of upper strata magnet ring 10A, lower floor's (or internal layer) Each white space of magnet ring 10B staggers predetermined angle relative to the corresponding white space of upper strata (or outer layer) magnet ring 10A. As shown in Fig. 6 b-6c, Fig. 7 and Figure 12 a-12b with Figure 13, each S magnetic poles of lower floor (or internal layer) magnet ring 10B are relative to upper strata The corresponding S magnetic poles of (or outer layer) magnet ring 10A stagger predetermined angle, each white space phase of lower floor (or internal layer) magnet ring 10B Stagger predetermined angle for the corresponding white space of upper strata (or outer layer) magnet ring 10A.

By taking clockwise direction movement of the x layers of magnet ring 10 into figure shown in arrow as an example, lower floor (or internal layer) magnet ring 10B is corresponded to Hall detection components 20B outputs the corresponding Hall detection components 20A of inductive signal hysteresis upper strata (or outer layer) magnet ring 10B Preset phase angle.

Specifically, the first predetermined angle or second predetermined angle can be determined according to the following formula, or it is described 3rd pre- If angle：

D=360 °/s/x

Wherein, d is the first predetermined angle or second predetermined angle, or the 3rd predetermined angle, x are the layer of magnet ring Number, s are the sum of number of N magnetic poles and S magnetic poles when being distributed multiple N magnetic poles and multiple S magnetic poles in the detection faces of every layer of magnet ring, Alternatively, be the sum of number of N magnetic poles and white space when being distributed multiple N magnetic poles in the detection faces of every layer of magnet ring, or every It is the sum of number of S magnetic poles and white space when being distributed multiple S magnetic poles in the detection faces of layer magnet ring.

In other words, s is magnetic pole total number, and when being distributed multiple N magnetic poles and multiple S magnetic poles on every layer of magnet ring, magnetic pole is always a Number refers to the sum of the number of the N magnetic poles and S magnetic poles predetermined angle that staggers；When being spaced apart multiple N magnetic poles on every layer of magnet ring, magnetic pole is total Number refers to the sum of number of N magnetic poles and white space；When being spaced apart multiple S magnetic poles on every layer of magnet ring, magnetic pole total number refers to S The sum of number of magnetic pole and white space.

Specifically, exemplified by with the number of plies x=2, the magnetic pole total number s=24 of every layer of magnet ring 10 of magnet ring 10, according to formula d The predetermined angle that=360 °/s/x is calculated can obtain d=7.5 °, i.e., stagger 7.5 ° between two neighboring Hall detection components 20.More Specifically, as shown in Fig. 2-13, the magnetic pole of lower floor (or internal layer) magnet ring 10B and the corresponding magnetic pole of upper strata (or outer layer) magnet ring 10A Between stagger 7.5 °, correspondingly, when x layers of magnet ring 10 rotate clockwise, the inspection of lower floor (or internal layer) magnet ring 10B corresponding Halls The inductive signal of component 20B outputs is surveyed relative to the sense of the corresponding Hall detection components 20A outputs of upper strata (or outer layer) magnet ring 10A Induction signal lags 90 °.

One embodiment according to the present utility model, Hall detection components 20 generate the first level simultaneously in face N magnetic poles Second electrical level is generated in face S magnetic poles, or Hall detection components 20 generate the first level and in face in face N magnetic poles Second electrical level is generated during the first white space, or Hall detection components 20 generate the first level and just in face S magnetic poles To generating second electrical level during the second white space, x road feels induction signal can construct the combination of y kinds level state, y>x.Wherein, according to One embodiment of the utility model, the quantity y of level state combination are the x of the level state quantity of each road feel induction signal Times, i.e. y=2x.

As shown in figure 14, control unit 30 includes：Timer 301 and control chip 302.

Wherein, timer 301 in any of y kinds level state combination level state by being combined into based on current start When, timing is carried out with the duration to every kind of level state combination in the combination of y kinds level state；Control chip 302 and timing Device 301 is connected, and control chip 302 is also connected with x Hall detection components 20, and control chip 302 is in any level state group The duration of conjunction judges that clamping stagnation occurs for moving component when being more than preset time threshold.

The predetermined angle that is, width for the N magnetic poles or S magnetic poles that x layers of magnet ring 10 match magnet ring 10 staggers, so that x The x road feels induction signal that Hall detection components 20 export respectively staggers preset phase angle successively, thus synchronization can form difference Level state combination.Control chip 302 is by detecting whether the duration that each level state combines exceedes preset time Threshold value can determine whether moving component occurs clamping stagnation.Thus, using multilayer magnet ring, magnet ring stagger arrangement distribution, while it is equipped with identical The Hall detection components of number, can further shorten detection time at double, can reach the effect for reducing detection time at double.
