Abstract
The invention discloses a shear type mechanism capable of controlling a shape through a numerical value. The shear type mechanism comprises multiple shear type units connected end to end to form an annular structure, and a numerical value control component, wherein the annular structure is driven by the numerical value control component to automatically finish a spreading or shrinking action; the numerical value control component comprises a driving motor, a driving wheel, a transmission piece and a driven wheel fixed on one shear type unit; the driving wheel, driven by the driving motor to rotate, drives the driven wheel to rotate through the transmission piece; the driven wheel drives the shear type unit fitted thereon to rotate; and the rotated shear type unit drives the adjacent shear type units to adaptively rotate; and thus the whole annular structure finishes the spreading or shrinking action. The shear type mechanism adopts an upper-layer plate and a lower-layer plate with plate type structures, so that the upper and lower layers can support each other in the spreading state without easily generating shake and damage, and can form a complete annular part after the shrinkage.

Embodiment
Below in conjunction with the drawings and specific embodiments, embodiment of the present invention are described in detail.It will be understood to those of skill in the art that the following drawings and embodiment are only the preferred embodiment of the present invention, so that understand the present invention better, thus should not be considered as limiting scope of the present invention.For a person skilled in the art, the present invention can have various modifications and variations, within the spirit and principles in the present invention all, and any amendment done, equivalent replacement or improvement etc., all should be included within protection scope of the present invention.
As shown in Figures 4 and 5, a kind of COUNTABLY VALUED controls the scissors mechanism of shape; Comprise the scissors unit 100 of some end to end structures circlewise, described scissors unit 100 comprises hinge 101 and mutually stacking top plate 102, lower plywood 103 form, and described hinge 101 is successively through described top plate 102 and lower plywood 103;
The two ends of described top plate 102 and lower plywood 103 are provided with pin joint 104, and described top plate 102 is hinged by the described lower plywood 103 of described pin joint 104 respectively with adjacent; Two pin joints 104 of same described top plate 102 and described hinge 101 be not on same straight line, when top plate 102 and lower plywood 103 relatively rotate around described hinge 101, between the top plate 102 of adjacent scissors unit 100 and the sidewall of lower plywood 103, form through hole 3.
In a scissors unit, top plate 102 is identical with the structure of lower plywood 103, when top plate 102 relatively rotates around hinge 101 with lower plywood 103, if top plate 102 is along rotating clockwise, under the effect of the tractive force that the lower plywood 103 be then attached thereto produces in it turns clockwise process, rotate in the counterclockwise direction; After lower plywood 103 rotates counterclockwise, drive again the top plate 102 of its opposite side to rotate clockwise, transmit so successively, thus realize the flexible of ring texture; And in same scissors unit, between top plate 102 and lower plywood 103, relatively turning on the difference of angle, then whole ring texture telescopic level is also different, and the contour structures that scissors structure presents is also different.
And top plate 102 and lower plywood 103 relatively rotate around hinge 101, change except hole 2 except being formed between each scissors unit 100, form through hole 3, flexible structure between the top plate of adjacent scissors unit 100 and the sidewall of lower plywood, can be used as through hole, loss of weight etc.
Because scissors structure 100 is under the state stretched, stressedly compare dispersion, therefore easily occur the situation that bending damages, load is large not; The present invention adopts top plate 102 and the lower plywood 103 of platy structure, make it two-layerly up and down when extended configuration can mutually support, be less likely to occur to rock and damage (as Fig. 5), and after contractions, one piece of complete annular element can be become, as Fig. 7.
The minimum angle of two pin joints respectively and between the line of its geometric center of described top plate 102 is β (β can be divided exactly by 360), and the quantity of described scissors unit 100 is equal with the operation result of (360 °/β).

As shown in Figures 5 and 6, the edge line of described top plate 102 and described lower plywood 103 is by straight-line segment and the end to end formation of curved line; Described scissors unit 100 join end to end circlewise structure time, described curved line forms the outline of described ring texture, and described straight-line segment forms the Internal periphery of described ring texture.
When whole scissors structure can fully be contracted in together, between adjacent upper plate 102 by straight-line segment and arc-shaped side bonded to each other, adjacent lower plywood 103 is same so; And in each scissors unit 100, the arc-shaped side of top plate 102 overlaps with the arc-shaped side of lower plywood 103, then form the outward flange of whole scissors structure, such scissors compact conformation nature, external periphery outline is smooth attractive in appearance.
As shown in Figures 7 and 8, the optimal value of described minimum angle β is 60 °.
When relatively rotating in maximum angle between the top plate 102 in each scissors unit 100 and lower plywood 103, the inner ring of described loop configuration and outer shroud present regular hexagon structure, Stability Analysis of Structures, good looking appearance.
As shown in Figure 1, Figure 2 and Figure 3, described ring texture automatically completes the action launching or shrink under the driving of Numerical Control assembly 400;
Described Numerical Control assembly 400 comprises drive motor 401, driving wheel 402, driving member 403 and is fixed on the engaged wheel 404 of a described scissors unit 100, the described driving wheel 402 of rotation is driven by described drive motor 401, described engaged wheel 404 is driven to rotate by driving member 403, described engaged wheel 404 drives the described scissors unit rotational of secure fit with it, the described scissors unit 100 rotated drives adjacent scissors unit to do adaptive rotation, then whole described ring texture completes the action launching or shrink.
By adjusting the parameters such as the rotating speed of drive motor 401, realizing the control to driving wheel 402 rotating speed, is also the adjustment to engaged wheel 404 rotating speed, so control effectively to the degree of whole described ring texture expansion or contraction, improves the practicality of device.
Described driving wheel 402, driving member 403 and engaged wheel 404 is pitch wheel.
The precision of gears meshing is high, carries out more effective control to the extension degree of described ring texture.
