Description
Technical field
The utility model relates to automatic control technology fields, and in particular to a kind of electric operator knob-operated device.
Background technique
In automatic control system, electric operator is critically important component part, and most of electric operator is all
Having the function of knob-operated, that is, several knobs being mounted on electric operator can change actuating mechanism controls mode,
Or directly control executing agency's operation.
There are many modes for the realization of knob-operated function, have and are directly wired to circuit board, are revolved with this to detect
The movement of button, which destroys the globality and leakproofness of executing agency, so that external operating unit is difficult with internal circuit
Reach high-grade leakproofness and explosion-proof performance.Also there are other to use the mode of non-contact detection, for example pass through physical isolation
Afterwards, the tongue tube by the combine detection of magnet and tongue tube, but in which is mechanical structure, and the service life is not grown, and is easy
Being shaken etc. influences, and be easy to cause the knob-operated of mistake, brings irremediable influence.
Utility model content
For the above defect of the existing technology, the main purpose of the utility model is to overcome the deficiencies in the prior art
Place discloses a kind of electric operator knob-operated device, including circuit board, aluminium sheet, be arranged on the aluminium sheet
One knob and the second knob and five Hall elements being arranged on the circuit board, the circuit board are arranged in the aluminium
The reverse side of plate, Hall element described in two of them are symmetrical arranged, and first knob is arranged in the projection centre of the aluminium sheet, and
And magnet is set on the first knob, the other three Hall element is distributed in equilateral triangle, is set in the projected position of the aluminium sheet
Second knob to be set, and magnet is set on second knob, the magnet is for triggering the Hall element, and five
The Hall element is connect with five output interfaces respectively.
Further, first knob uses self- recoverage type knob, and second knob uses maintenance knob.
Further, the magnet is using cylindrical axial charging magnet.
The utility model obtain the utility model has the advantages that
The beneficial effects of the utility model are embodied in: by non-contact detection, so that circuit part and external activity portion
Part is effectively isolated, and can achieve higher sealing grade and explosive-proof grade, while Hall element is compared to devices longevity such as tongue tubes
Order it is longer, incude it is sensitiveer, stability is more preferable.Whole device externally provides five output signal interfaces, has respectively represented two
The trigger event of knob totally five positions, enough electric operators use.
Detailed description of the invention
Fig. 1 is a kind of positive structure schematic of electric operator knob-operated device of the utility model；
Fig. 2 is a kind of reverse structure schematic of electric operator knob-operated device of the utility model.
Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, with reference to the accompanying drawing and implement
Example is described in further detail the utility model.It should be appreciated that specific embodiment described herein is only to explain this reality
With novel, it is not used to limit the utility model.
A kind of electric operator knob-operated device of the utility model, as shown in Figs. 1-2, including circuit board, aluminium sheet,
Five Hall elements of the first knob 11 on aluminium sheet and the second knob 12 and setting on circuit boards are set, wherein two
A Hall element is symmetrical arranged, and the first knob 11 is arranged in the projection centre of aluminium sheet, and magnet 3 is arranged on the first knob,
By rotating the first knob 11, the position of magnet 3 is controlled, when being moved at Hall element, is exported to induction signal.Likewise, another
Outer three Hall elements are distributed in equilateral triangle, the second knob 12 are arranged in the projected position of aluminium sheet, and on the second knob
Magnet is set, by rotating the second knob 12, controls the position of magnet 3, when being moved at Hall element, exports to induction signal.
Five Hall elements are connect with five output interfaces respectively, and then control corresponding electric operator.
Specifically, the first knob 11 uses self- recoverage type knob, release can automatically return to default location, and there are two sprocket bits
It sets, when knob 1 is failure to actuate, magnet m1 is at the p0 of position, and the circuit board of the reverse side of corresponding aluminium sheet does not have Hall element, so
5 output interfaces do not have signal output at this time；Knob 1 rotates clockwise 90 °, at magnet m1 in-position p2, corresponding Hall
Element c2 senses magnetic field, passes through interface i2 output signal；Knob 1 is rotated by 90 ° counterclockwise, right at magnet m1 in-position p1
The Hall element c1 answered senses magnetic field, passes through interface i1 output signal.By artificially rotating appointing in 1 to two positions of knob
It anticipates at one, then can export corresponding signal by output interface, unclamp knob, knob 1 returns to default location p0, and output interface is same
When stop output signal.
Second knob 12 uses maintenance knob, unclamps and stops to the position rotated, and there are three position location, three positions
It sets apart from one another by 120 ° of distributions.When magnet m2 is at the p3 of position, corresponding Hall element c3 senses magnetic field, passes through interface
I3 output signal；When magnet m2 is at the p4 of position, corresponding Hall element c4 senses magnetic field, is exported and is believed by interface i4
Number；When magnet m2 is at the p5 of position, corresponding Hall element c5 senses magnetic field, passes through interface i5 output signal.
In one embodiment, magnet is using cylindrical axial charging magnet.
The above is only the preferred embodiments of the utility model, are not used to limit the scope of the utility model；If
The spirit and scope for not departing from the utility model, are modified or replaced equivalently the utility model, should all cover in this reality
In novel scope of protection of the claims.
