Abstract
The utility model discloses a high stability piezoceramics drives piece, including substrate and piezoceramics wafer, be equipped with protruding type piece on the terminal surface of substrate both sides, protruding type piece includes a plurality of toper lugs and spherical lug, the toper lug with the crisscross multirow that is provided with in the spherical mutual interval of lug, the correspondence has been seted up to piezoceramics wafer bottom the spill draw -in groove of protruding type piece, the piezoceramics wafer passes through the bottom the butt joint of spill draw -in groove the adhesion of protruding type piece in on the terminal surface of substrate both sides. In this way, the utility model discloses it is more firm to make substrate and piezoceramics wafer bond, improves the stability of piezoceramics drive piece, increase of service life.
Description
Technical field
The utility model relates to piezoelectric ceramics driving piece field, particularly relates to a kind of high stability piezoelectric ceramics driving piece.
Background technology
Piezoelectric ceramics driving piece is made up of monolithic piezoelectric ceramic sheet or biplate piezoelectric ceramic piece and a flexible substrates, produces the braking plate of respective curved displacement under voltage driven.
Because substrate can generate heat in the process of conduction, and traditional piezoelectric ceramics driving piece poor radiation, piezoelectric ceramics driving piece temperature can be caused to raise, the situations such as deformation easily occur and reduces useful life.
Utility model content
The technical problem that the utility model mainly solves is to provide a kind of high stability piezoelectric ceramics driving piece, substrate and piezoelectric ceramic wafer can be made to bond more firm, improve the stability of piezoelectric ceramics driving piece, increase the service life.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: provide a kind of high stability piezoelectric ceramics driving piece, comprise substrate and piezoelectric ceramic wafer, described substrate both sides end face is provided with convex block, described convex block comprises multiple taper projection and spherical protrusions, described taper projection and the mutual interleaved of described spherical protrusions are provided with many rows, the spill draw-in groove of corresponding described convex block is offered bottom described piezoelectric ceramic wafer, described piezoelectric ceramic wafer docks described convex block by bottom described spill draw-in groove and adheres on the end face of described substrate both sides.
In the utility model preferred embodiment, the corresponding described taper projection of spill draw-in groove bottom described piezoelectric ceramic wafer and described spherical protrusions offer conical socket in staggered interval and arc groove.
In the utility model preferred embodiment, described convex block and described substrate are integrated syndeton.
In the utility model preferred embodiment, described taper projection and described spherical protrusions top all flush equal altitudes and arrange.
In the utility model preferred embodiment, described substrate and described piezoelectric ceramic wafer are bondd by binding agent.
In the utility model preferred embodiment, described substrate is glass mat or carbon fiber board.
The beneficial effects of the utility model are: it is more firm that the utility model can make substrate and piezoelectric ceramic wafer bond, and improves the stability of piezoelectric ceramics driving piece, increase the service life.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, 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:

Embodiment
Be clearly and completely described to the technical scheme in the utility model embodiment below, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, the utility model embodiment comprises:
A kind of high stability piezoelectric ceramics driving piece, comprise substrate 1 and piezoelectric ceramic wafer 2, described substrate 1 both sides end face is provided with convex block 3, described convex block 3 comprises multiple taper projection 301 and spherical protrusions 302, described taper projection 301 and described spherical protrusions 302 each other interleaved are provided with many rows, offer the spill draw-in groove 4 of corresponding described convex block 3 bottom described piezoelectric ceramic wafer 2, described piezoelectric ceramic wafer 2 docks described convex block 3 by bottom described spill draw-in groove 4 and adheres on the end face of described substrate 1 both sides.
In addition, the corresponding described taper projection 301 of the spill draw-in groove 4 bottom described piezoelectric ceramic wafer 2 and described spherical protrusions 302 offer conical socket in staggered interval and arc groove.
In addition, described convex block 3 is integrated syndeton with described substrate 1.
In addition, described taper projection 301 and described spherical protrusions 302 top all flush equal altitudes setting.
In addition, described substrate 1 is bondd by binding agent with described piezoelectric ceramic wafer 2.
In addition, described substrate 1 is glass mat or carbon fiber board.
Operation principle of the present utility model for be provided with convex block 3 on the end face of substrate 1 both sides, convex block 3 and substrate 1 are integrated syndeton, convex block 3 comprises multiple taper projection 301 and spherical protrusions 302, taper projection 301 and spherical protrusions 302 each other interleaved are provided with many rows, taper projection 301 and spherical protrusions 302 top all flush equal altitudes and arrange, the spill draw-in groove 4 of corresponding convex block 3 is offered bottom piezoelectric ceramic wafer 2, the corresponding taper projection 301 of spill draw-in groove 4 bottom piezoelectric ceramic wafer 2 and spherical protrusions 302 offer conical socket in staggered interval and arc groove, piezoelectric ceramic wafer 2 docks convex block 3 by Bottom concave draw-in groove 4 and adheres on the end face of substrate 1 both sides, substrate 1 and piezoelectric ceramic wafer 2 are bondd by binding agent, due to taper projection 301 and spherical protrusions 302 each other interleaved arrange can be firm piezoelectric ceramic wafer 2 is adhered on the end face of substrate 1 both sides, because taper projection 301 and spherical protrusions 302 are provided with, how row is multiple, piezoelectric ceramic wafer 2 can be very firm adhesion, not easily occur to peel off dropping situations.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description 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 utility model.
