Mechanism in power switch.
Trigger mechanism is provided with at least two magnet 51,52, and at least one of which is permanent magnet；One magnet
51 are arranged on clutch end 4, and another magnet 52 is arranged on active side.It is arranged on clutch end 4
The movement locus of magnet, the position of the magnet in active side.The magnet of clutch end 4, with
Magnet in active side, for the magnetic force relation attracted each other.
The stroke of clutch end 4 at least, inhale with the magnet in active side by the magnet of clutch end 4
Close, the stroke separated to two magnets.After magnet separates, magnetic interaction reduces rapidly, causes gold
Belong to substrate 21 and lose magnetic force constraint, produce resilience, and then produce vibration.
Base 1 is provided with position limiting structure, and position limiting structure is arranged on personal movable part by clutch end 4
The movable track of pulling force on.After clutch end 4 pulls active side to move to position limiting structure, limited
Blocking of bit architecture, resistance increases, and causes two magnets to separate, active side resilience, and produces vibration,
And then generation electric energy.
The stroke of clutch end 4 at least, inhale with the magnet in active side by the magnet of clutch end 4
Closing, the resilience force to metal substrate 21 is more than the stroke that magnetic force causes two magnets to separate.Limit can be saved
Bit architecture, makes structure simplify.
Trigger mechanism is provided with at least two magnet, and two are permanent magnet.Or, trigger mechanism be provided with to
Few two magnets, one be permanent magnet one be soft magnetic bodies.
Magnet can be soft magnetic bodies or permanent magnet.Permanent magnet may is that neodymium iron boron (Nd2Fe14B) permanent magnetism
Body, SmCo (SmCo) permanent magnet, aluminum nickel cobalt (AlNiCo) permanent magnet, ferrite permanent-magnet materials (Ferrite)
At least one in permanent magnet.Soft magnetic bodies can be the soft magnetic bodies such as iron plate, stalloy.Arrange with active side
Magnet, as counterweight.So that simplification structure.
Trigger mechanism is the trigger mechanism clashing into suddenly piezoelectric ceramic piece 2.Piezoelectricity is made to make pottery by clashing into suddenly
Ceramics 2 produces vibration.
Suddenly the trigger mechanism clashed into, in such as labor-saving stapler, is pressed into certain dynamics or stroke
After, discharge suddenly, draw up staple.Can be by release suddenly, the mode drawing up staple clashes into pressure
Electroceramics sheet 2.
Clutch end 4 is provided with resetting-mechanism.Realize resetting after completing to trigger.Resetting-mechanism can be adopted
With spring, magnet, or self gravitation resets.
The power intake 3 of trigger mechanism is a button.Or, the power intake 3 of trigger mechanism is
One pedal.Further, the power intake of trigger mechanism can also be a turning handle.Trigger mechanism
Power intake can also be a runner.The power intake of trigger mechanism can also be a stay cord.Trigger
Mechanism is also secured on base 1.So that realizing integrated design.
Trigger mechanism is the stroke trigger mechanism discharging piezoelectric ceramic piece 2 after one stroke exceedes setting value.
Such as, base 1 is provided with position limiting structure, and position limiting structure is arranged on personal movable part by power
On the track that the pulling force of outfan 4 is movable.After arriving position limiting structure, it is achieved depart from release.
Trigger mechanism is the pulling force trigger mechanism discharging piezoelectric ceramic piece 2 after a pulling force exceedes setting value.
Clutch end 4 is provided with and the hook of active side mounting, and the stroke of clutch end 4 is at least,
Clutch end 4 hook mounts with active side, and the resilience force to metal substrate 21 is more than the power of locked by hooks
Amount causes the stroke that hook separates with free activity.When pulling force is excessive, hook departs from, and produces vibration.
Trigger mechanism be the clutch end 4 of be thumb wheel, thumb wheel is provided with at least two tooth, adjacent
It is provided with active side between two teeth.Rotated by thumb wheel and stir active side, produce vibration.
Energy-storage type piezoelectric generating device also includes a regulator rectifier circuit, and it is steady that piezoelectric ceramic piece 2 connects rectification
