One white space is distributed in the detection faces of magnet ring 10, i.e., the arrangement rule on magnet ring 10 is the clear area of N magnetic poles-the first
Domain the-the first white space of-N magnetic poles；When interval is full of S magnetic poles on magnet ring 10, S magnetic poles are distributed in magnet ring with white space
In 10 detection faces, i.e., the arrangement rule of magnet ring 10 is S magnetic poles the-the second white space-S the-the second white spaces of magnetic pole, wherein,
It is nonmagnetic region without any magnetic that white space, which includes the first white space or the second white space,.Thus, in this hair

When moving component is moved, N magnetic poles and gambler's white space can be alternately across Hall detection components 20, and Hall detection components 20 are by root
Corresponding induced signal is exported according to the pole change sensed.Or, it can be spaced on circular magnet ring 10 full of S magnetic poles and the
Two white spaces, when driving part drive motion components are moved, S magnetic poles and the second white space can be detected alternately across Hall
Component 20, Hall detection components 20 will export corresponding induced signal according to the pole change sensed.
Control unit 30 is connected with Hall detection components 20, and whether control unit 30 judges moving component according to induced signal
Clamping stagnation.
Specifically, illustrated exemplified by multiple N magnetic poles are spaced apart in the detection faces of magnet ring 10, drive and transport in driving part
When dynamic component is moved, magnet ring 10 is moved with driving part, and Hall detection components 20 are fixed, in the detection faces of magnet ring 10
N magnetic poles and the first white space pass sequentially through Hall detection components 20, the N that Hall detection components 20 pass through reaction magnetic ring 10
Magnetic pole is to export induced signal such as low and high level pulse signal, and when driving part stop motion, Hall detection components 20 are felt
The magnetic pole that should be arrived will keep constant, and induced signal will keep constant, thus, and control unit 30 judges to drive according to induced signal
Whether the state of part, such as driving part occur stall, and then judge whether the moving component that driving part is driven occurs
Clamping stagnation.
The situation and the foregoing situation for being spaced apart multiple N magnetic poles of multiple S magnetic poles are spaced apart in the detection faces of magnet ring 10
Similar, difference is, the S magnetic poles and the second white space in the detection faces of magnet ring 10 pass sequentially through Hall detection components 20, this
In repeat no more.
According to one embodiment of present invention, driving part may include motor, and magnet ring 10 is fixed on motor
On runner assembly.That is, when motor drive motion components are moved, magnet ring 10 is with the runner assembly of motor
Rotate.
According to one embodiment of present invention, motor can be stepper motor, and stepper motor uses opened loop control, controls
Whether unit 30 can occur stall by the structure detection stepper motor of magnet ring and Hall detection components, prevent stepper motor from continuing
In interference state, prevent to stepper motor in itself and product operation has a negative impact.
According to one embodiment of present invention, the runner assembly of motor can be travelling gear or drive shaft.Namely
Say, magnet ring 10 can be fixed in the travelling gear of motor or drive shaft, so that, when motor is rotated, magnet ring 10 can be with
Rotation.
It should be noted that when motor drive motion components, if through multiple between motor and moving component
Magnet ring 10, then be preferably fixed on the travelling gear of moving component by travelling gear.
Specifically, as shown in Figure 2-5, fixing hole 101 is provided with magnet ring 10, for example, the center of magnet ring 10 is provided with fixing hole
101, magnet ring 10 by the runner assembly riveted of fixing hole 101 and driving part such as motor, so as to driving part
Synchronous axial system.That is, magnet ring 10 can pass through fixing hole 101 and the travelling gear or drive shaft riveted of motor.In addition,
Magnet ring 10 also can directly make a part with travelling gear.
Also, according to one embodiment of present invention, Hall detection components 20 can be fixed in air conditioner body.Thus,
Integral installation is convenient, it is to avoid bring routing problem.
Further, according to one embodiment of present invention, as shown in Figure 2-5, multiple N magnetic poles or S magnetic poles are with wide side
Formula is set.That is, when being spaced apart multiple N magnetic poles in the detection faces of magnet ring 10, the width all same of each N magnetic poles；
Or when being spaced apart multiple S magnetic poles in the detection faces of magnet ring 10, the width all same of each S magnetic poles.According to the present invention's
One specific example, magnetic regions be N magnetic pole magnetics region width and the first white space width also can approximately equal, or
Person's magnetic regions are that the width and the width of the second white space in S magnetic pole magnetics region also can approximately equals.
It should be noted that the width of magnetic regions and white space is more narrow better on the premise of magnetic field intensity is ensured,
1-2 millimeters can for example be accomplished, magnetic field intensity is required depending on the hall sensing parameter according to Hall detection components 20.
Specifically, the magnetic regions angular breadth of N magnetic poles or S magnetic poles can be obtained according to below equation：
λ=(π+arcsin (X/A)+arcsin (Y/A))/p,
Wherein, λ is the magnetic regions angular breadth of N magnetic poles or S magnetic poles, and A is close for the maximum magnetic flux of N magnetic poles or S magnetic poles, and X is suddenly
The operating point of your detection components 20, Y is the point of release of Hall detection components 20, and p is the number of N magnetic poles or S magnetic poles.
Correspondingly, the region angular breadth of the first white space or the second white space can be obtained according to below equation：
θ=2 π/p-λ
Wherein, θ is the region angular breadth of the first white space or the second white space, and λ is N magnetic poles or the S magnetic poles
Magnetic regions angular breadth, p is the number of N magnetic poles or the S magnetic poles.
However, it is to be understood that the width of the width of N magnetic poles and the first white space can be equal, the width of S magnetic poles and
The width of second white space also can be equal, so as to simplify design, the manufacture difficulty of magnet ring.
In addition, magnet ring 10 is that N magnetic poles are alternate with white space or S magnetic poles are alternate with white space, N magnetic poles or S magnetic
The number of pole is related to the size of magnet ring 10, and the size of magnet ring 10 is bigger, and the total number of N magnetic poles or S magnetic poles is more, detects sensitive
Degree is higher.
According to one embodiment of present invention, Hall detection components 20 are monopole type Hall element, monopole type Hall element
20 and magnet ring 10 between the magnetic of magnetic pole match, wherein, when being spaced apart multiple N magnetic poles in the detection faces of magnet ring 10,
Monopole type Hall element is N polar form Hall elements；When being spaced apart multiple S magnetic poles in the detection faces of magnet ring 10, monopole type is suddenly
Your element is S polar form Hall elements.That is, the type selecting of monopole type Hall element coordinates with monopole magnet ring, if monopole magnetic
The magnetic of the detection faces of ring is N polar forms, then monopole type Hall also selects N polar forms, if the magnetic of the detection faces of monopole magnet ring is S
Polar form, then monopole type Hall is also from S polar forms.
According to the specific embodiment of the present invention, as shown in Figure 2-5, the detection faces of magnet ring 10 can be magnet ring side or magnetic
Ring end face.That is, magnet ring 10 has, side is magnetized and end face magnetizes two kinds of forms, is illustrated by taking N magnetic poles as an example, such as Fig. 2 a, figure
2b and Fig. 4 show side and magnetized, and N magnetic poles and the first white space interval can be full of to the periphery of magnet ring 10, wherein, such as Fig. 2 a
For top view, such as Fig. 2 b and Fig. 4 are side view；Magnetized as shown in Figure 3 and Figure 5 for end face, can be by N magnetic poles and the first white space
End face of the interval full of magnet ring 10.In embodiments of the present invention, preferable end face magnetizes, thinner from can do magnet ring 10, section
Material saving, reduces cost.
According to one embodiment of present invention, such as Hall element of Hall detection components 20 can use paster and plug-in type two
Packing forms are planted, Hall detection components 20 are each attached to PCB (Printed Circuit Board；Printed circuit board) on plate simultaneously
It is fixed on by pcb board in air conditioner main body,, can induction range in magnetic field close to magnet ring but noncontact positioned at the side of magnet ring 10
It is interior.
Wherein, as shown in figure 5, the magnet ring 10 that the Hall detection components 20 of patch-type can magnetize with end face is engaged；Such as Fig. 4
Shown, the magnet ring 10 that the Hall detection components 20 of plug-in type can magnetize with side is engaged.In embodiments of the present invention, preferably
The Hall detection components 20 of patch-type, because in manufacture craft, patch-type positioning is more accurate, so as to reduce detection error, and
Automated assembly can be easy to using patch-type, assembling speed is lifted.
According to one embodiment of present invention, white space, Hall is distributed between two adjacent N magnetic poles or S magnetic poles
Detection components 20 can be according to whether the N magnetic poles or S magnetic poles sensed generates induced signal, i.e. Hall detection components just to N magnetic
Significant level is generated when pole or S magnetic poles, and inactive level is generated when just to the first white space or the second white space, for example
Significant level can be high level and inactive level can be low level, or, significant level can be low level and inactive level can be
High level, depending on the self attributes of Hall detection components 10.
So, when N magnetic poles and the first white space are alternately across Hall detection components 20 or S magnetic poles and the second clear area
When domain is alternately across Hall detection components 20, Hall detection components 20 will export stable low and high level pulse train, and height
The cycle of level pulse sequence is fixed, dutycycle is 50%.
Thus, the N magnetic poles or S magnetic poles on magnet ring 10 can be accomplished very intensive (magnet pole widths can accomplish 1-2mm), sensitive
Degree is high, can improve the frequency of feedback pulse, so as to shorten detection time, improve detection sensitivity.Moreover, based on Hall
Effect, it is reliable and stable, it is disturbed low, impulse waveform is stable, and low and high level saltus step is rapid.
Further, according to one embodiment of present invention, as shown in fig. 6, control unit 30 includes：The He of timer 301
Control chip 302.
Wherein, timer 301 is used to start timing when significant level and inactive level are switched over, with to significant level
Duration and inactive level duration carry out timing,；Control chip 302 is connected with timer 301, control chip
302 are used to judge that clamping stagnation occurs for moving component when the duration of significant level or inactive level being more than preset time threshold.
Specifically, illustrate by taking N magnetic poles as an example, the situation and N magnetic poles of S magnetic poles are similar, are no longer described in detail.In driving
During part drive motion components movement such as motor rotation, the runner assembly of motor drives the synchronous axial system of magnet ring 10,
Hall detection components 20 are fixed, and the N magnetic poles and the first white space on magnet ring 10 are alternately across Hall detection components 10, such as
N magnetic pole of the fruit Hall detection components 10 just to magnet ring 20, the then output of Hall detection components 20 significant level, now timer 301
The duration of significant level is recorded, T1 is designated as；If first white space of the Hall detection components 20 just to magnet ring 10, suddenly
Your detection components 20 export the duration of inactive level, now the protocol failure level of timer 301, are designated as T2.It should be understood that
, by rationally setting the N magnetic poles of magnet ring 10 and the width of the first white space for example, the magnetic regions angular breadth of N magnetic poles
For λ=(π+arcsin (X/A)+arcsin (Y/A))/p, and the region angular breadth of the first white space is θ=2 π/p-λ, can be made
T1 is identical with T2.
Hall detection components 20 just to region change to the first white space from N magnetic poles when, Hall detection components 20
Output jumps to inactive level from significant level, and timer 301 restarts timing, the i.e. invalid electricity of the start recording of timer 301
The flat duration.It is similar, Hall detection components 20 just to region change to N magnetic poles from the first white space when, Hall
The output of detection components 20 jumps to significant level from inactive level, and timer 301 restarts timing, i.e. timer 301 and opened
The duration of beginning record significant level.
Thus, the rest may be inferred, as shown in fig. 7, Hall detection components 10 export a series of low and high level pulse train, and
And the dutycycle of pulse train is 50%.Control chip 50 by detecting duration of high level and low level lasting respectively
Time i.e. whether more than preset time threshold be can determine whether motor whether stall, and then judge door-plate whether clamping stagnation.
More specifically, it is assumed that r is the rotating speed of magnet ring 10, p is the N magnetic poles of magnet ring 10 or the number of S magnetic poles, then does not block
In the case of stagnant, the duration tn of significant level or inactive level is 1/r/p/2, i.e. tn=1/r/p/2, wherein, magnet ring 10
Rotating speed r can be calculated according to the rotating speed and gear transmission velocity ratio of motor.
Thus, if clamping stagnation occurs for moving component, the travelling gear of driving part is stagnated, Hall detection components 20 just to
The region of magnet ring 10 no longer changes, and the output level of Hall detection components 20 can be continuously high level or be continuously low electricity
It is flat.
