Abstract
The utility model is a kind of miniature ultrasonic focusing motor, it comprises stator, the first oscillator and the second oscillator, in described stator one end face, be provided with groove, described the first oscillator is arranged in the groove of stator, described the second oscillator abuts the other end of stator, described the second oscillator other end is in abutting connection with piezoelectric element, and described stator is provided with the end face of groove successively in abutting connection with output gear and flange jaw, and described stator, the first oscillator and the second oscillator are arranged on same linear axis.Adopt technical solutions of the utility model, the entire length of motor is shortened, and the vibration frequency of stator can not raise yet.
Description
Technical field
The utility model relates to autofocus motor field, is specifically related to a kind of miniature ultrasonic focusing motor.
Background technology
Ultrasonic motor and traditional motor have very large difference, no matter traditional motor has how many kinds of, its principle generally changes electromagnetic force into rotatory force exactly, the rotatory force of ultrasonic motor is the energy that results from ultrasonic vibration, in order to cater to more configuring automatic focusing drive unit in narrow space, be necessary to shorten motor length, if still shorten design length simply, do not change element arrangements position, the resonance frequency of stator will be too high so, and this can reduce vibration wave amplitude on the contrary.
Utility model content
The purpose of this utility model is to overcome the problem that prior art exists, and a kind of miniature ultrasonic focusing motor is provided.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the utility model is achieved through the following technical solutions:
A kind of miniature ultrasonic focusing motor, it comprises stator, the first oscillator and the second oscillator, in described stator one end face, be provided with groove, described the first oscillator is arranged in the groove of stator, described the second oscillator abuts the other end of stator, described the second oscillator other end is in abutting connection with piezoelectric element, and described stator is provided with the end face of groove successively in abutting connection with output gear and flange jaw, and described stator, the first oscillator and the second oscillator are arranged on same linear axis.
Further, in the groove of described stator, be provided with Compress Spring, described Compress Spring one end is against bottom land, and the other end pushes against output gear.
The beneficial effects of the utility model are:
Adopt technical solutions of the utility model, the entire length of motor is shortened, and the vibration frequency of stator can not raise yet.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Number in the figure explanation: 1, the first oscillator, the 2, second oscillator, 3, stator, 4, piezoelectric element, 5, output gear, 6, flange jaw, 7, linear axis, 8, Compress Spring, 9, locking wheel, 10, latch segment.
Embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the utility model in detail.
Shown in Fig. 1, a kind of miniature ultrasonic focusing motor, mainly comprise stator 3, the first oscillator 1 and the second oscillator 2, in the present embodiment, described stator is provided with groove in 3 left sides, its groove forms vibration chamber, described the first oscillator 1 is arranged in the groove of stator 3, and be arranged on linear axis 7, the shaft shoulder of itself and linear axis, between axial plane, also form a small oscillation chamber, the two sides of the first oscillator 1 is all vibration chamber, described the second oscillator 2 abuts the right side of stator 3, described the second oscillator 2 other ends are in abutting connection with piezoelectric element 4, lock with locking wheel 9 on piezoelectric element 4 right sides, described stator 3 is provided with the end face (left side) of groove successively in abutting connection with output gear 5 and flange jaw 6, high order end is locked by latch segment 10, described stator 3, the first oscillator 1 and the second oscillator 2 are arranged on same linear axis 7, in the groove of described stator 3, be provided with Compress Spring 8, described Compress Spring 8 one end are against bottom land, the other end pushes against output gear 5.
Principle of the present utility model:
Ultrasonic vibration is the fundamental driving force of motor rotation, in the utility model, in drives piezoelectric element 4, possess different directions electrode layer and send ultrasonic wave, self expanding and shrinking meeting (amplifying by the second oscillator 2) of the different directions of piezoelectric element 4 causes that stator 3 tips swing slightly or swing, final result is whenever voltage direction changes 90 degree (a part of process of power supply), the vibration of the piezoelectric layer both sides of piezoelectric element 4 will in conjunction with and produce the vibration wave of a very little rotation (each produce a vibration wave in cycle, amplitude 0.002mm), this ripple makes stator 3 tail ends make circus movement among a small circle, the energy that stator 3 rotates passes to output gear 5 by the elastic force (amplifying by the first oscillator 1) of Compress Spring 8, drive its running.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection range of the present utility model.
