Abstract
The invention discloses a coding-digital inputting device of a rotary-type switch for adjusting current of an electric water pump, which comprises a machine box, and a rotary-reversely switch and a rotary-forwardly switch which are mounted in the machine box, wherein the rotary-forwardly switch and the rotary-reversely switch are arranged at interval in a face-to-face manner; the output ends of the rotary-forwardly switch and the rotary-reversely switch are electrically connected with a digital coder; the middle parts of the rotary-forwardly switch and the rotary-reversely switch are provided with deflecting rods which are swung left and right and have reset springs; gears are mounted below the deflecting rods; the tail parts of the deflecting rods are fallen in gear grooves of the gears; knobs are mounted on the gears in a rigid manner; when the knobs are rotated continuously in a clockwise or an anticlockwise manner, the deflecting rods are located below the gears and the reset springs; the head parts of the deflecting rods are swung intermittently and impact the rotary-forwardly switch or the rotary-reversely switch intermittently; after switch signals of the rotary-forwardly switch or the rotary-reversely switch are processed through the digital coder, signals are output in a number increasing progressively or a digital decreasing progressively manner. The device disclosed by The invention has the advantages of simple and reasonable structure, hand-feel and phonoreception in a number increasing or reducing procedure, long service life, strong anti-interference capacity, and working reliability.
Description
Technical field
The present invention relates to a kind of rotary switch coded digital input unit that is used for the electric water pump current calibration.
Background technology
With the electric water pump current calibration is example; When manual work setting, editor's protection parameter, the general button adjustment numeral that indicates "+", "-", its weak point: common switching signal poor anti jamming capability of adopting; The button adjustment does not have feel, and button damages malfunctioning easily.
Summary of the invention
The objective of the invention is to overcome deficiency of the prior art, a kind of rotary switch coded digital input unit that is used for the electric water pump current calibration that when adjustment numeral increases or reduces, has feel, phonoreception, long service life, that antijamming capability is strong, functional reliability is provided.
The object of the invention is achieved through following technical proposals: comprise the machine box and be installed in reversal switch wherein, positive switch; Said positive switch, the face-to-face alternate layout of reversal switch, both outputs are electrically connected with digital encoder, the driving lever of the band back-moving spring that both middle installations can swing; Gear is installed in the below of said driving lever, and the driving lever afterbody drops in the gear grooved of gear, and the driving lever head is in the centre of positive switch and reversal switch; Rigidity is installed knob on the said gear; When knob rotated clockwise continuously, driving lever was following gear and back-moving spring, and the swing of head batch (-type) ground and the batch (-type) of driving lever clash into positive switch; When knob rotated counterclockwise continuously, driving lever was following gear and back-moving spring, the head batch (-type) ground swing of driving lever and batch (-type) bump reversal switch; After the switching signal of positive switch or reversal switch is handled through digital encoder, the signal output that increases progressively or successively decrease with numeral.
The afterbody of said driving lever is installed reed, and reed drops in the gear grooved of gear.
Said positive switch and reversal switch adopt the trigger switch of sealed type.
Compared with prior art, the present invention has the following advantages: simple and reasonable, when adjustment numeral increases or reduces, have feel, the phonoreception of rattling away, long service life, strong, the functional reliability of antijamming capability.
Description of drawings
Fig. 1 is one embodiment of the invention structural representation block diagram.
Among the figure: 1-digital encoder, 2-reversal switch, 3-driving lever, the positive switch of 4-, 5-reed, 6-gear grooved, 7-gear, 8-machine box, 9-knob.
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described further:
Referring to accompanying drawing, comprise machine box 8 and be installed in reversal switch 2 wherein, positive switch 4; Said positive switch 2, reversal switch 4 face-to-face alternate layouts, both outputs are electrically connected with digital encoder 1, the driving lever 3 of the band back-moving spring that both middle installations can swing; Gear 7 is installed in the below of said driving lever 3, and driving lever 3 afterbodys drop in the gear grooved 6 of gear 7, and driving lever 3 heads are in the centre of positive switch 2 and reversal switch 4; Rigidity is installed knob 9 on the said gear 7; When knob 9 rotated clockwise continuously, driving lever 3 was following gear and back-moving spring, and the swing of head batch (-type) ground and the batch (-type) of driving lever 3 clash into positive switch 4; When knob 9 rotated counterclockwise continuously, driving lever 3 was following gear and back-moving spring, the head batch (-type) ground swing of driving lever 3 and batch (-type) bump reversal switch 2; After the switching signal of positive switch 4 or reversal switch 2 is handled through digital encoder 1, the signal output that increases progressively or successively decrease with numeral.
Described afterbody is installed reed 5, and reed 5 drops in the gear grooved 6 of gear 7.
The trigger switch of said positive switch 2 and reversal switch 4 employing sealed types.
Digital encoder 1: adopt prior art, with A, B, three end points outputs of C.
Embodiment 1:
Embodiment 2:
On the basis of embodiment 1, described afterbody is installed reed 5, and reed 5 drops in the gear grooved 6 of gear 7.When adjustment numeral increases or reduces, have feel, simultaneously, send the sound of rattling away between the tooth of reed 5 and wheel.Because positive switch 2 and reversal switch 4 have adopted the trigger switch of sealed type, can obviously prolong useful life, the digital signal that obtains after common switching signal is handled through digital encoder 1, and antijamming capability is strong.
