In the present embodiment, a lattice scale sense refers to the first multipole magnet during rotation, magnetic damping magnet and first
Active force between multipole magnet is from attracting → → attracting complete procedure of repelling each other.Since the rotation of magnetic idler wheel is turned around i.e. more than first
Magnet rotation in pole is turned around it is possible that multiple above-mentioned complete procedures, so total lattice number of scale sense may also be more lattice.This reality
Example is applied because magnetic damping magnet is fixed, so the first multipole magnet of magnetic idler wheel can once jump two magnetic poles when rotated, because of this
The first multipole magnet can pass through the magnetic pole in a magnetic damping magnet with the magnetic pole same sex on magnetic idler wheel in the process, so having one
Repulsive force between a magnetic pole, final magnetic idler wheel can be kept and magnetic damping magnet there is a natural attraction between the sexes state.In magnetic idler wheel rotary course
In attraction this process for returning again to that there is a natural attraction between the sexes by repulsive force it is general just as scale sense.The machine of scale sense and mechanical rollers
Tool screens is similar, has the screens occurred due to the repulsive force because identical charges repel each other the phenomenon that after rotation, magnetic idler wheel is allowed to rotate each time
When each screens it is the same just as a lattice scale, limit the angle that rotates every time.

In the present embodiment, a lattice scale sense refers to magnetic damping magnet and the first multipole magnet during rotation, magnetic
Active force between damping magnet and the first multipole magnet is from attracting → → attracting complete procedure of repelling each other.Since magnetic idler wheel revolves
I.e. the first multipole magnet that turns around rotation is turned around it is possible that multiple above-mentioned complete procedures, so total lattice number of scale sense also may be used
Can be more lattice.The present embodiment is because magnetic damping magnet can also rotate, and magnetic damping magnet can be because of the first multipole magnet of magnetic idler wheel when initial
Effect that there is a natural attraction between the sexes and be driven to rotate, when magnetic damping magnet and the first multipole magnet this two magnet are all on the side of reversal
When boundary, of short duration identical charges repel each other effect is had, subsequent two magnet can all go to next magnetic pole, come back to the shape that there is a natural attraction between the sexes
State.Attraction this process for returning again to that there is a natural attraction between the sexes by repulsive force in magnetic idler wheel rotary course is general just as scale sense.
Scale sense is similar with the mechanical screens of mechanical rollers, there is the card occurred due to the repulsive force because identical charges repel each other the phenomenon that after rotation
Position, each screens is the same just as a lattice scale when magnetic idler wheel being allowed to rotate each time, limits the angle rotated every time.
It is further used as preferred embodiment, further includes MCU and multiple Hall subassemblies, the multiple Hall subassembly is located at
In the magnetic field of first multipole magnet, the output end of the multiple Hall subassembly is connect with the input terminal of MCU.
Also using multiple Hall subassemblies, the first multipole magnet arranged in pairs or groups on MCU and magnetic idler wheel comes real the utility model
The continuous data read-write of existing handwriting equipment.Idler wheel when rotated, drives the rotation of the first multipole magnet to generate changing magnetic field, the change
Multiple Hall subassemblies effect in the magnetic field and fixed position of change generates Hall effect (Hall Effect).Because of each Hall group
The position of part is different, so under the same time, the Hall voltage (phase, electric current etc.) that each Hall subassembly is incuded is not
Identical, the continuous data that handwriting equipment can be realized according to this phenomenon by cooperation MCU is read and write.
The utility model is further explained and is illustrated with specific embodiment with reference to the accompanying drawings of the specification.
This specific embodiment discloses a kind of reluctance force generation technology that magnetic idler wheel technology of arranging in pairs or groups on handwriting equipment uses.
The technology has increased another multipole magnet (this specific embodiment newly under the premise of not interfering the spatial position of multiple Hall subassemblies
Entitled magnetic damping magnet), different size of reluctance force is provided by the distance between magnetic damping magnet and magnetic idler wheel.Its
In, magnetic damping magnet can be fixed, and also rotatably, the distance with magnetic idler wheel still can be changed.When magnetic idler wheel is rotating
When, because of the phenomenon that identical charges repel each other so that when magnetic idler wheel rotates, the scale sense of one lattice of a lattice is had, when magnetic damping magnet is apart from magnetic
When idler wheel is close, scale sense is apparent, and the resistance that idler wheel rotates is larger；When magnetic damping magnet is gradually remote apart from magnetic idler wheel,
Scale sense can reduce, and rotate can be more smooth for magnetic idler wheel.
By taking Fig. 5 as an example, it is assumed that the magnetic pole sum of the first multipole magnet is 16, and the magnetic pole sum of magnetic damping magnet is 2, works as magnetic
The first multipole magnet is driven to rotate when idler wheel is rotated by external force, magnetic damping magnet also can and then be revolved because of the attraction that magnetic field generates
Turn.When the rotation of the first multipole magnet reaches position shown in fig. 6 more than 11.25 degree, the magnetic damping magnet of 2 poles can be from because of the same sex
Repel each other and be changed to from the state of being attracted by repulsion state, is arrived so the first multipole magnet of magnetic idler wheel can be pushed to next magnetic pole
Up to position shown in Fig. 7, meanwhile, the magnetic damping magnet of two poles can be also rotated by 90 ° again, be changed to be attracted shape from by repulsion state
State.
That is, after the first multipole magnet (i.e. idler wheel) rotation shown in fig. 6 is more than 11.25 degree, because of the magnet same sex
Repel each other and the physical phenomenon that there is a natural attraction between the sexes, allows idler wheel to jump into 22.5 degree from 11.25 degree with having power-assisted, at this time the first multipole magnet
This two magnet is attracting with magnetic damping magnet, if without external force, just no longer rotates.At this time magnetic idler wheel to the use feeling of people just as machine
Tool idler wheel is the same, there is mechanical screens after rotation, makes each screens that magnetic idler wheel rotates each time the same as a lattice scale, limit
The fixed angle rotated every time.Certainly it can also apply sufficiently large external force, magnetic idler wheel is allowed to rotate always, but magnetic idler wheel is by a card
, just there is the generation of a scale sense in position.
As shown in figure 3, when the fixation of magnetic damping magnet does not rotate, magnetic idler wheel revolves the quantity for corresponding scale sense of turning around,
For the first multipole magnet number of magnetic poles divided by 2.By taking the magnetic idler wheel of 16 poles as an example, when the fixation of magnetic damping magnet does not rotate, magnetic idler wheel
Rotation is turned around, and the scale sense of 8 lattice is had.
As shown in figs. 4-7, when magnetic damping magnet is rotatable, magnetic idler wheel revolves the quantity for corresponding scale sense of turning around, with
First multipole magnet number of magnetic poles is identical.By taking the magnetic idler wheel of 16 poles as an example, when magnetic damping magnet is under rotatable state, magnetic idler wheel
Rotation is turned around, and the scale sense of 16 lattice is had.
In addition, magnetic damping magnet, can also use instead can be substituted by metal material that magnet attracts.As shown in Fig. 2, when gold
Category 4 is closer apart from magnetic idler wheel (i.e. the first multipole magnet 1), and the resistance of magnetic idler wheel rotation is bigger；Metal 4 is remoter apart from magnetic idler wheel,
The resistance of idler wheel rotation is smaller.4 unlimited shape of metal, if it can have an effect with magnetic idler wheel, but such reluctance force occurs
Mode, magnetic idler wheel do not have scale sense when rotated.
And after the magnetic damping magnet separate effective distance of effect with magnetic idler wheel, magnetic idler wheel can be without scale sense, and because of resistance
Become smaller and can glidingly rotate very much.
The structure of tradition system mechanical rollers is as shown in Figure 8 and Figure 9, generally can remove apical tooth disk 26 using spring 72, so its
When rotated, spring 72 and 26 reciprocation of fluted disc generate scale sense and the sound, but because fluted disc 26 is plastic material, so its
The problem of having frictional dissipation.And the magnetic damping device of the utility model, other than it can provide reluctance force, moreover it is possible to which scale is provided
Sense, the problem of will not having the sound, and not have frictional dissipation.
In conclusion a kind of magnetic idler wheel damping unit of the utility model, uses and is made of magnetic idler wheel and magnetic damp mechanism
Magnetic idler wheel damping unit replace traditional mechanical rollers, only need to be by adjusting magnetic idler wheel and magnetic damping magnet or intermetallic
Distance can utilize magnetic force principle to provide different size of reluctance force, meet the smooth degree of different idler wheels and want
It asks, different materials need not be used, it is flexibly, versatile, and magnetic force extends the use of idler wheel without frictional dissipation
Service life there will not be the sound.The utility model can adjust the smooth of magnetic idler wheel under the premise of no frictional dissipation by distance
Degree, the scale sense quantity that can be also adjusted by total number of magnetic poles of the first multipole magnet, this is that tradition machinery idler wheel is difficult to reality
Existing.
It is to be illustrated to the preferable implementation of the utility model, but the utility model is not limited to the reality above
