Specific embodiment
The present invention will be further described in detail with reference to the accompanying drawings and detailed description.
As shown in figure 4, a kind of rocker switch low-power consumption trigger device, the wraping plate including driving mechanism 40 and its transmission connection
Mechanism, wraping plate mechanism are set on 10 wraping plate 11 of rocker switch, the connection of the driving mechanism 40 control chip and detection driving machine
The electric current of the current measuring instrument of 40 electric current of structure, current measuring instrument measurement, which amplifies and filters to export, gives control core for voltage waveform
Piece.
Preferably, the driving mechanism 40 is steering engine or decelerating motor.
Preferably, the wraping plate mechanism is one group of trigger arm 20, and bottom is respectively arranged at wraping plate lifting both ends, upper part
30 two sides of output shaft of driving mechanism 40 are not connected to by connector, the connector is gear, 40 positive and negative rotation of driving mechanism
It drives the movement of trigger arm 20 to press 11 two sides of wraping plate and realizes that wraping plate carries out switch motion.
Preferably, the control chip is single-chip microcontroller, model stm32f103.
A kind of triggering method of low-power consumption trigger device as described in any one of the above embodiments, includes the following steps:
It is powered to driving mechanism, driving wraping plate mechanism drives rocker switch to be rotated；
It measures the electric current of driving mechanism and records its waveform variation tendency, judge whether electric current reaches second crest value,
It is to control chip to power off the driving mechanism.
Preferably, judge the method whether electric current reaches second crest value are as follows:
Measure driving mechanism electric current, and electric current is amplified and filter export for voltage waveform to control chip at
Reason；
It when judging whether voltage reaches second crest value, is to control chip to power off the driving mechanism.
Preferably, the current waveform is approximate with voltage waveform variation tendency: when energization, voltage rises with electric current；Driving
When mechanism works, voltage falls to voltage rating and rated current with electric current；When wraping plate mechanism presses rocker switch, voltage is with electricity
Stream rises；When elastomeric element acts, voltage declines with electric current.
Preferably, the voltage reaches the detection method of second crest value are as follows:
Setting voltage detecting interval time is t, and i-th of voltage detecting value is Ui, (i-1) a voltage detecting value is Ui-1,
△ U=Ui-Ui-1；

To second crest value.
As shown in figure 3, dotted line is the current waveform flowed through using overcurrent power-off method driving mechanism, solid line is using this hair
The current waveform that bright method power-off driving mechanism flows through, Fig. 2 are to amplify and filter to input at control chip to the electric current
The voltage waveform of reason.
As shown in Figure 1, driving mechanism starts immediate current by the process of liter above freezing, since control chip cannot be received directly
The current value of current measuring instrument acquisition, therefore the overdrive electric current of mechanism of convection current is needed to amplify and filter and input to control core
Piece, control chip pins carry out data processing judgement to the voltage waveform and have filtered out due under the rising again of initial start-up transient electric current
The trend curve of drop.After starting driving mechanism starts turning, driving mechanism just has electric current to flow through, when the touching that driving mechanism drives
When hair arm is not pressed into wraping plate and starts, electric current is steady and smaller, when trigger arm is pressed into rocker switch and starts effect,
Driving mechanism will receive at this time causes electric current to rise by the resistance that trigger arm passes over, and gradually increases in the process strength of pressing
Greatly, electric current is also gradually increased therewith, and when rocker switch reaches critical triggering, rocker switch is due to by inner elastomeric component
Effect quickly contacts internal circuit, and trigger arm will not reach rocker switch at this time, and stress disappears, and electric current is begun to decline,
Voltage waveform is close with current waveform, controls chip at this time and detects that voltage reaches second crest value and closes driving mechanism immediately
Power supply does not allow driving mechanism to continue to drive trigger arm pressing rocker switch until electric current stall, and motor continues to turn when due to power-off
Dynamic, voltage becomes negative value, and until motor stalls, voltage falls to zero.The method can effectively improve mechanical part
Service life simultaneously can reduce energy consumption.
The foregoing is merely presently preferred embodiments of the present invention, all equivalent changes done according to scope of the present invention patent with
Modification, is all covered by the present invention.
