The specific embodiment
Below in conjunction with the specific embodiment and accompanying drawing, the utility model is further illustrated.
The utility model is made the moving cell serial connection by least one and is formed, and when the serial connection next one is made moving cell, a upper rotation end 1 of making moving cell becomes the stiff end 3 that the next one is made moving cell.Comprise rotation end 1, fork 2 and the stiff end 3 set gradually as moving cell, fork 2 is connected with U-shaped groove on rotation end 1 by connecting axle 2-4 on it, and connecting axle 2-4 fixes by insulating nut 2-5 at two ends, and fork 2 is fixedly connected with by insulation screw 7 with stiff end 3.With stiff end 3 bilateral symmetry, dielectric elastomer 4 is set at rotation end 1.Described dielectric elastomer 4 inner surface fixed bondings are rotating the side of end 1 with stiff end 3, and the outer surface of dielectric elastomer 4 part bonding with rotating end 1 and stiff end 3 compressed by pressing plate 6, to prevent dielectric elastomer 4, comes off.The screwed hole rotated on end 1 and stiff end 3 sides is fixing with dielectric elastomer 4 by pressing plate 6 by insulation screw 7.The inside and outside surface of this dielectric elastomer 4 scribbles conductive paste 5, and every side conductive paste 5 is connected with external power source by wire.
As Fig. 4 (a), 4(b), 4(c) as shown in, described fork 2 is formed by connecting by bar I 2-1, bar II 2-2, bar III 2-3, connecting axle 2-4 and nut 2-5, fork 2 only has the function of swinging and can not stretching motion, so arrange and not only effectively support prestretched dielectric spring shape body 4, prevent its retraction, and improved the swing reliability, bar I 2-1, bar II 2-2, bar III 2-3 and nut 2-5 adopt the polysulfones rod to process, connecting axle 2-4 adopts the rod iron of diameter ￠ 2, during rotation, frictional resistance is little, and rigidity is high, be not easy distortion.
Described dielectric elastomer 4 is film-form, specifically can adopt the materials such as VHB series polyacrylic acid elastomer, film-form CF19-2186 colloidal silica, film-form HS3 colloidal silica, film-form HN-1110T type DE material or film-form polyurethane.
As illustrated in Figures 5 and 6, the described rotation end 1 of making moving cell, it is good that stiff end 3 all adopts with dielectric elastomer 4 cementabilities, quality is light, rigidity is high, be not easy to be out of shape acetal resin material, rotating end 1 is rectangular frame structure with stiff end 3, the two ends of rotating end 1 one sides arrange U-shaped groove, rotate end 1 and stiff end 3 all the other equal hollow outs, reduce quality, rotate end 1 and the middle installing hole that coaxially is provided with of stiff end 3, while pasting dielectric elastomer 4, insert braking roll at installing hole, for preventing when rotating the dielectric elastomer 4 of end 1 and stiff end 3 both sides stickup prestretcheds, as moving cell, rotate, pressing plate 6 adopts the nylon material that thickness is 0.3mm～0.5mm, and this quality of materials is light, good with dielectric spring shape body 4 cementabilities.Rotate end 1 horizontal and vertical according to 3 * 3 times～5 * 5 times (preferably 4 * 4 times) prestretcheds with the dielectric elastomer 4 that stiff end 3 bilateral symmetry arrange, the dielectric elastomer 4 that the dielectric elastomer 4 of every side setting is 1～5 layer of (preferably 3 layers) prestretched is formed by stacking.It is identical that the dielectric elastomer 4 prestretched rates of both sides and the number of plies of stack keep, and guarantees to rotate the suffered pulling force in end 1 both sides identical, makes oscillation actuating mechanism in poised state.So, after prestretched, the thickness of dielectric elastomer 4 is less, and driving voltage is lower, and distortion and the power output of dielectric elastomer 4 are larger, and driveability is more excellent.
The conductive paste 5 of dielectric elastomer 4 inside and outside surface coating is apart from the free direction of dielectric elastomer 4 two ends 1.5mm, dielectric elastomer 4 outer surfaces that contact with pressing plate 6 and with rotate to hold 1, dielectric elastomer 4 inner surfaces that stiff end 3 contacts coating electrically conductive cream 5 not, so adopt, prevent that dielectric elastomer 4 from producing insulation breakdown, and dielectric elastomer 4 is more firm with the cementability that rotates end 1, stiff end 3, pressing plate 6.
This oscillation actuating mechanism can be connected in series needed swing and make moving cell according to the situation of swing needs, and the rotation end 1 of doing on moving cell is made the stiff end 3 of moving cell as next one serial connection.
At ordinary times, the retraction force of the suffered prestretched dielectric elastomer 4 in oscillation actuating mechanism both sides is identical, and oscillation actuating mechanism is in the poised state shown in Fig. 2.When the dielectric elastomer 4 of oscillation actuating mechanism one side is subject to voltage drive, dielectric elastomer 4 areas of this side increase, retraction force reduces, opposite side is symmetrically arranged does not execute alive dielectric elastomer 4 retractions, area reduces, the oscillation actuating mechanism disequilibrium, and the rotation end 1 of making moving cell drives fork 2 rotations, be flapped toward a side of the dielectric elastomer 4 of not switching on as moving cell, as shown in Figure 3.In like manner, when the dielectric elastomer 4 of oscillation actuating mechanism opposite side is subject to voltage drive, as moving cell, be flapped toward opposite side.
The utility model, by applying voltage drive, is controlled and is made dielectric elastomer 4 stretching motions on moving cell, drives fork 2 and swings, and realizes swinging of oscillation actuating mechanism.The efficient mobility that this oscillation actuating mechanism swings and flexibility are to be determined by the start unit number that swings actuation mechanism, by doing, the moving cell pendulum angle is cumulative to be formed the oscillation actuating mechanism pendulum angle, the start unit number is more, the oscillation actuating mechanism pendulum angle is just larger, the flexibility of oscillation actuating mechanism is just larger, and its flexible swinging is just higher.
