Piezoelectric driving type software displacement driver

Abstract

The invention relates to a piezoelectric driving type software displacement driver which comprises a first clamping structure, a first piezoelectric vibrator, a telescopic structure, a second piezoelectric vibrator, a second clamping structure and liquid. The clamping structures and the telescopic structure are composed of columnar software membranes and are filled with the liquid, and the piezoelectric vibrators are arranged between the clamping structures and the telescopic structure. When bending recovery deformation happens to the first piezoelectric vibrator under the action of voltages, reciprocating deformation happens to a thickness decreasing area on the first clamping structure, friction force of the clamping structures is changed periodically, telescopic deformation of the telescopic structure is combined, and the motion of a whole machine in the direction of the first clamping structure is formed. When bending recovery deformation happens to the second piezoelectric vibrator, the motion of the whole machine in the direction of the second clamping structure is formed. Due to the fact that the software driver is made of piezoelectric materials, the problem that function materials adopted by a current software driver are free of industrialization scale production is solved.

Problems solved by technology

Traditional software drivers generally use functional materials and pneumatic drives. It is difficult to miniaturize the power components of pneumatic drives. Therefore, functional materials such as shape memory alloys and electric Mars polymers are generally used as power sources. These types of functional materials At present, they have not yet entered the stage of industrial production, which limits the practical application of software drivers.
