Detailed description of the invention
The core of the present invention is to provide a kind of rotary switch, and this rotary switch has higher explosion-proof, shockproof and dust-proof
Performance, goes for multiple special industry and occasion.
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Describe, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments wholely.Based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under not making creative work premise
Embodiment, broadly falls into the scope of protection of the invention.
Refer to the longitudinal sectional view that Fig. 1, Fig. 1 are the rotary switch in the specific embodiment of the invention.
In a kind of specific embodiment scheme, the invention provides a kind of rotary switch, this rotary switch includes housing 5 He
Main shaft 8, main shaft 8 is pivotably coupled to the end cap 6 of housing 5 around own axes, and main shaft 8 is positioned on the shaft part within housing 5 same
Axle is fixed with gear 3 and magnet ring 11, the end abutment of magnet ring 11 in gear 3, the inwall of housing 5 be provided with corresponding with gear 3 in
Gear ring 4, the crown of gear 3 all uses at radially exist gap, gear 3 and the ring gear 4 of main shaft 8 with the crown of ring gear 4
Ferrimagnet, main shaft 8 is positioned at the end within housing 5 and is fixed with magnetic body 13, and N pole and the S pole of magnetic body 13 lay respectively at
The axis both sides of main shaft 8, housing 5 is additionally provided with circuit board 15, and circuit board 15 is positioned at the side within housing 5 and is fixed with and magnetic source
The reception chip 14 for receiving magnetic field variation signal that body 13 is relative.
The operation principle of this rotary switch is as follows: owing to gear 3 and ring gear 4 are ferrimagnet, therefore, magnet ring 11
Contacting with gear 3 and gear 3 is produced magnetization, making each crown of gear 3 produce magnetic, the crown of gear 3 is to housing 5
Ring gear 4 crown produce sucking action.When main shaft 8 rotates, the captivation of ring gear 4 crown is hindered by gear 3 crown
The rotation of main shaft 8, it is therefore desirable to overcome gear 3 crown captivation (i.e. reluctance force) to ring gear 4 crown.Gear 3 crown with
Ring gear 4 crown is to timing, and the captivation at crown is maximum, and gear 3 is followed main shaft 8 and rotated often through a tooth of ring gear 4
During point, then through a maximum magnetic flux resistance point, be equivalent to through a wave band, and next ring gear 4 crown and gear 3 crown
Captivation effect then position to gear 3 there is the function of correction automatically, namely captivation effect can make gear 3 crown
Align with ring gear 4 crown automatic suction, be i.e. adapted to the maximum magnetic flux resistance point that adjacent crown is located relatively.Meanwhile, when main shaft 8 end
When the magnetic body 13 of end follows main shaft 8 one logical rotation, magnetic body 13 produces a continually varying N-S pole friendship to receiving chip 14
For magnetic field, after reception chip 14 receives magnetic field variation signal, this magnetic field variation signal is carried out inner core chip level process, to rear
Continuous circuit produces an analogue signal being similar to sine and cosine waveform, and original sine and cosine analogue signal is through differential amplification etc.
Can produce after reason the pulse signal of AB passage, i.e. user can digital pulse signal.
It should be noted that magnet ring 11 is set in main shaft 8 periphery and follows main shaft 8 and together rotate, magnet ring 11 connects with gear 3
Touching, owing to gear 3 is ferrimagnet, therefore magnet ring 11 can produce magnetization effectiveness, such that it is able to make gear 3 to gear 3
Magnetic is produced at each crown.Housing 5 can be designed as a tubular structure, can accommodate in the inner chamber of housing 5 main shaft 8 and
Its gear 3 parts such as grade realize freely rotatable.It is of course also possible to housing 5 is designed as other structures, repeat no more herein.At shell
The inwall of body 5 is provided with the ring gear 4 corresponding with gear 3, and ring gear 4 is also ferrimagnet, and therefore, the crown of gear 3 is permissible
The crown of ring gear 4 is produced sucking action, and this captivation (reluctance force) is exactly the active force producing wave band sense.
When main shaft 8 rotates, gear 3 often through a maximum magnetic flux resistance point, is equivalent to through a wave band, and this ripple
Section has automated location debugging functions, can be adapted to next maximum magnetic flux resistance point.The automated location makeover process of gear 3 is concrete
For: when gear 3 is in some maximum magnetic flux resistance point, rotating main shaft 8, now, driver part needs to overcome this maximum magnetic resistance
The magnetic force sucking action in force, the moment that namely driver part drive shaft 8 rotates needs the magnetic more than maximum magnetic flux resistance point
Force square, main shaft 8 just can rotate, when the crown of gear 3 turns to the point midway between two teeth of ring gear 4,
Magnetic force sucking action is minimum, and main shaft 8 continues to rotate, and makes the maximum magnetic flux resistance point that the crown of gear 3 moves closer to and departs from before
At the crown of the ring gear 4 that position is adjacent, namely move closer to next maximum magnetic flux resistance point, when the crown of gear 3 rotates
To the crown with next ring gear 4 to timing, magnetic force sucking action reaches maximum, now discharges the driving force of driver part,
Gear 3 is just fixed on next maximum magnetic flux resistance point by magnetic force sucking action, here it is the automated location correction merit of gear 3
Energy.
Radially there is gap at main shaft 8 in the crown of the crown of gear 3 and ring gear 4, the size in this gap can affect
To the magnetic force sucking action of two corresponding crowns, in order to ensure that gear 3 crown and ring gear 4 crown have enough attraction and make
With, thus ensure to have and significantly rotate wave band sense, it is preferable that the crown of the crown of this programme middle gear 3 and ring gear 4 is being led
The gap width radially of axle 8 is 1.2mm～1.8mm.

Multiple teeth of wheel 3 are uniformly distributed, and multiple teeth of ring gear 4 are also uniformly distributed, and the spacing of the most adjacent two teeth is equal, and
The number of teeth of gear 3 and ring gear 4 is equal, and i.e. each tooth of gear 3 and each tooth one_to_one corresponding of ring gear 4, be arranged such, when
When main shaft 8 rotates, multiple crowns of gear 3 and multiple crowns of ring gear 4 are one by one to timing, and the reluctance force that main shaft 8 is subject to is just
It is making a concerted effort of multiple crown captivation, therefore can strengthen the wave band sense that reluctance force is formed.
It should be noted that those skilled in the art can arrange wave band according to the occasion that rotary switch is specifically applied
The most number of teeth of particular number, the quantity of wave band and gear 3 or ring gear 4 is corresponding.The ring gear 4 of such as gear 3 and housing 5
The number of teeth be 24, then when main shaft 8 rotates a circle, just through 24 magnetic resistance forces, i.e. corresponding 24 wave bands, each wave band
There is a maximum magnetic flux resistance point.
