Abstract
The utility model discloses a novel piezoelectric actuator. The novel piezoelectric actuator comprises a vibration plate, a ceramic vibrator and a pedestal, wherein the vibration plate is connected with the pedestal; and the ceramic vibrator is arranged between the vibration plate and the pedestal. According to the utility model, an additional mechanism is used for amplifying the vibrator, so larger vibration output can be obtained under the equivalent power consumption, and heat exchanging efficiency of products is improved. The novel piezoelectric actuator which is stable in quality and easy to transport is protected by a housing and suitable for all kinds of application environment.
Description
Technical field
The utility model relates to a kind of actuator, is specifically related to a kind of novel piezoelectric actuator.
Background technology
Existing piezoelectric actuated product mostly is single ceramic vibrator on the market at present; its vibratory output is all smaller; cannot meet the demand to high vibration force; and single ceramic vibrator does not in use have external protection; very easily damage, and higher to the sensitivity of temperature humidity, under the operating state such as hot and humid; its electric property can change thereupon, and the stability of product is also unstable.The industry of having relatively high expectations for product stability, and it is larger to use instrument and equipment under severe environmental conditions to be badly in need of a kind of vibration force, the piezo-activator of stability of characteristics makes up the market demand.
Utility model content
The purpose of this utility model is to overcome the problem that prior art exists, and a kind of novel piezoelectric actuator is provided.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the utility model is achieved through the following technical solutions:
A novel piezoelectric actuator, involving vibrations plate, ceramic vibrator and base, described oscillating plate is connected with described base, between described oscillating plate and described base, is provided with described ceramic vibrator.
Further, on described oscillating plate, be provided with cantilever, center vibrating disk, contact and oscillating plate locating ring, described base comprises central supported point and the base locating ring that is positioned at intermediate position, and the bottom centre position of described ceramic vibrator is connected with described base locating ring, and top perimeter position contacts with some described contacts, top, described contact contacts with described center vibrating disk, and described center vibrating disk periphery is described cantilever.
The beneficial effects of the utility model:
The utility model utilizes additional mechanism design that vibration source is amplified, and can obtain larger vibration output under equal power consumption, to improve product conversion efficiency, and concrete shell protection, steady quality, is easy to transportation, applicable types of applications environment.

Embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the utility model in detail.
Shown in seeing figures.1.and.2, a kind of novel piezoelectric actuator, involving vibrations plate 1, ceramic vibrator 2 and base 3, described oscillating plate 1 is connected with described base 2, is provided with described ceramic vibrator 2 between described oscillating plate 1 and described base 2.
Further, on described oscillating plate 1, be provided with cantilever 1-1, center vibrating disk 1-2, contact 1-3 and oscillating plate locating ring 1-4, described base 3 comprises central supported point 3-1 and the base locating ring 3-2 that is positioned at intermediate position, and the bottom centre position of described ceramic vibrator 2 is connected with described base locating ring 3-2, and top perimeter position contacts with some described contact 1-3,1-3 top, described contact contacts with described center vibrating disk 1-2, and described center vibrating disk 1-2 periphery is described cantilever 1-1.
Principle of the present utility model:
During the utility model work, first ceramic vibrator 2 accesses produce vibration after driving signal, because ceramic vibrator 2 bottom centre positions are connected with base locating ring 3-2, its vibration force is mainly distributed by periphery, and some contact 1-3 contact with ceramic vibrator 2 top perimeter, transmission by contact 1-3 drives cantilever 1-1 to work, and then promotes center vibrating disk 1-3 work, drives whole actuator to produce judder.
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.
