Abstract
The invention discloses a piezoelectric ceramics driving piece. The piezoelectric ceramics driving piece comprises a substrate and piezoelectric ceramics chips, wherein a plurality of arc-shaped grooves are formed in the two side faces of the substrate, aluminum chips are arranged in the arc-shaped grooves, the aluminum chips and the arc-shaped grooves are correspondingly arranged, the aluminum chips are embedded into the arc-shaped grooves, thermal insulation pads are further arranged on the bottoms of the aluminum chips, the tops of the aluminum chips are arranged to protrude out of the surface of the substrate, and the piezoelectric ceramics chips are attached to the two side end faces of the substrate. Through the mode, the piezoelectric ceramics driving piece can have the advantages that the heat dissipation performance is better, the stability is improved, and the service life is prolonged.
Description
Technical field
The present invention relates to piezoelectric ceramics driving piece field, particularly relate to the piezoelectric ceramics driving piece that a kind of thermal diffusivity is superior.
Background technology
Piezoelectric ceramics driving piece is the conversion element of piezoelectric ceramic type slide cam selector, and piezoelectric ceramics driving piece, by inverse piezoelectric effect, makes piezoelectric ceramics driving piece generation deflection displacement and bending moment to control needle selection.And traditional piezoelectric ceramics driving piece is all adhered on substrate by piezoelectric ceramic wafer to form.But because the substrate of carbon fiber board material generates heat in the process of conduction, and traditional piezoelectric ceramics driving piece poor radiation, thus cause piezoelectric ceramics driving piece temperature to raise, can service life be affected.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of piezoelectric ceramics driving piece, and piezoelectric ceramics driving piece thermal diffusivity can be made better, improves stability, increases the service life.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of piezoelectric ceramics driving piece, comprise substrate and piezoelectric ceramic wafer, described substrate two sides offer multiple arc groove, aluminium chip is set in described arc groove, described aluminium chip is corresponding with described arc groove to be arranged, described aluminium chip embeds in described arc groove, described aluminium chip bottom is also provided with heat insulating mattress, described aluminium chip top protrudes from described substrate surface and arranges, and described piezoelectric ceramic wafer is attached on the end face of described substrate both sides.
In a preferred embodiment of the present invention, described heat insulating mattress is arranged between described aluminium chip and described arc groove.
In a preferred embodiment of the present invention, described heat insulating mattress is corresponding with described aluminium chip and described arc groove to be arranged in circular arc.
In a preferred embodiment of the present invention, it is 10 microns-20 microns that described aluminium chip protrudes from described substrate surface thickness.
In a preferred embodiment of the present invention, described substrate is glass mat or carbon fiber board.
The invention has the beneficial effects as follows: the present invention can improve piezoelectric ceramics driving piece thermal diffusivity by setting up aluminium chip, and then improving stability, increases the service life.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the embodiment of the present invention, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:
Fig. 1 is the structural representation of piezoelectric ceramics driving piece one of the present invention preferred embodiment;
In accompanying drawing, the mark of each parts is as follows: 1, substrate; 2, piezoelectric ceramic wafer; 3, arc groove; 4, aluminium chip; 5, heat insulating mattress.
Detailed description of the invention
Be clearly and completely described to the technical scheme in the embodiment of the present invention below, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making other embodiments all obtained under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1, the embodiment of the present invention comprises:
A kind of piezoelectric ceramics driving piece, comprise substrate 1 and piezoelectric ceramic wafer 2, described substrate 1 two sides offer multiple arc groove 3, in described arc groove 3, aluminium chip 4 is set, described aluminium chip 4 is corresponding with described arc groove 3 to be arranged, and described aluminium chip 4 embeds in described arc groove 3, is also provided with heat insulating mattress 5 bottom described aluminium chip 4, described aluminium chip 4 top protrudes from described substrate 1 surface and arranges, and described piezoelectric ceramic wafer 2 is attached on the end face of described substrate 1 both sides.
In addition, described heat insulating mattress 5 is arranged between described aluminium chip 4 and described arc groove 3.
In addition, described heat insulating mattress 5 is corresponding with described aluminium chip 4 and described arc groove 3 is arranged in circular arc.
In addition, described aluminium chip 4 protrudes from described substrate 1 surface thickness is 10 microns-20 microns.
In addition, described substrate 1 is glass mat or carbon fiber board.
Operation principle of the present invention for offer multiple arc groove 3 on substrate 1 two sides, aluminium chip 4 is set in arc groove 3, aluminium chip 4 is corresponding with arc groove 3 to be arranged, aluminium chip 4 embeds in arc groove 3, heat insulating mattress 5 is also provided with bottom aluminium chip 4, heat insulating mattress 5 is arranged between aluminium chip 4 and arc groove 3, heat insulating mattress 5 is corresponding with aluminium chip 4 and arc groove 3 to be arranged in circular arc, aluminium chip 4 top protrudes from substrate 1 surface and arranges, it is 10 microns-20 microns that aluminium chip 4 protrudes from substrate 1 surface thickness, piezoelectric ceramic wafer 2 is attached on the end face of substrate 1 both sides, because the substrate 1 of carbon fiber board material generates heat in the process of conduction, thus cause piezoelectric ceramics driving piece temperature to raise, service life can be affected, and be embedded in aluminium chip 4 due to substrate 1, when substrate 1 is heating up, first heat insulating mattress 5 can intercept partial heat, aluminium chip 4 simultaneously in arc groove 3 can absorb heat, piezoelectric ceramic wafer 2 is avoided, and temperature is too high affects performance.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present invention.
