Flexible piezoelectric fiber is may be used on curved-surface structure, is had broad application prospects in terms of novel intelligent material.
Another aspect inertia-type Piexoelectric actuator is because it is in impulse stroke, resolution ratio, working frequency, movement velocity, frequency
Rate response, manufacturing cost are had unique advantage by stagnant ring draw degree of piezoelectric element etc., have been developed as pressing
One pith of electric precision actuation.Existing piezoelectric inertia driving device mostly uses Asymmetric Electric signal as excitation letter
Number, but this driving device has the shortcomings that signal is not easy to generation, mechanism is not easily controlled, has larger rollback to move.In view of mesh
The problems of preceding piezoelectric inertia driving device, the present invention propose a kind of inertia jump Piezoelectric Driving dress based on flexible hinge
It sets, by the frictional force between control device and contact surface, Piexoelectric actuator is made to generate directed movement.It is simple with structure, easy
In realize, device reliability is high, without electromagnetic interference, pumping signal are easy to generate and control, device controllability is good the advantages that.
Summary of the invention
Technical problems to be solved needed for the present invention are: under electric signal excitation, piezoelectric fabric 1 (3), piezoelectric fabric 2 (6)
Elongation strain simultaneously, driving metal plate 1 (2) drive mass block (1) to swing, and the inertial impact force generated using mass block (1) is real
The movement of existing device entirety.
In order to solve the above technical problems, the technical scheme adopted by the invention is that:
The piezoelectric fabric is in parallel mutually Nian Jie using conducting resinl with metal plate.
The metal plate 1 (2) needs to process certain radian, to make it have better mechanical property, end adds
Work is at threaded post so as to quality of connection block (1).Mass block (1) has corresponding threaded hole simultaneously.
The metal plate 1 (2) and flexible hinge 2 (5) is machined with certain radian, and piezoelectric fabric 1 (3) is bonded in metal plate
