Embodiment Construction

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0035] It should be noted that if there is a directional indication (such as up, down, left, right, front, back...) in the embodiment of the present invention, the directional indication is only used to explain the position in a certain posture (as shown in the accompanying drawing). If the specific posture changes, the directional indication will also change accordingly.

[0036] In addition, if there are descriptions involving "first", "second" and ...

Abstract

The invention discloses a piezoelectric motor, the piezoelectric motor has a first direction and a second direction which are arranged in a crossed manner, the piezoelectric motor comprises a plurality of motor monomers, each motor monomer comprises a stator and a rotor which is movably arranged along the first direction relative to the stator, the plurality of stators of the plurality of motor monomers are arranged side by side along the second direction, and the plurality of rotors of the plurality of motor monomers are connected into a whole through a connecting structure. According to the invention, the arrangement of the plurality of motor single bodies helps to increase the total driving force of the piezoelectric motor; and, in addition, the plurality of stators are arranged side by side along the second direction, and the plurality of rotors are connected into a whole through the connecting structure, so that a plurality of driving forces of the plurality of motor monomers are in the same direction and are synchronous, and the total driving force of the piezoelectric motor is more precise and stable.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a piezoelectric motor. Background technique [0002] In small devices such as mobile communication devices and wearable devices, in order to drive small parts or movable mechanisms, such as telescopic cameras and telescopic movable mechanisms, motors that can move linearly are required. Traditional small linear motors require complex mechanical structures such as gears and cams to convert high-speed rotary motion into linear motion, and are prone to defects such as high current and overheating, large power consumption, and prone to mechanical failures. [0003] A piezoelectric motor is a motor that uses the piezoelectric inverse effect of a piezoelectric body to convert electromechanical energy. The existing piezoelectric motor is limited by the size, performance and friction coefficient of the piezoelectric body itself, and it is difficult to achieve a large driving force. Con...
