Embodiment
About aforementioned and other technology contents, characteristics and effect of the present invention, in a following cooperation DETAILED DESCRIPTION OF THE PREFERRED with reference to the accompanying drawings, can clearly present.
Consult Fig. 2 and Fig. 3, the preferred embodiment of image-taking device of the present invention comprises that a body 2, is positioned at an image module of body 2 (figure does not show) and a mirror surface structure 4.In this example, image-taking device is with camera explanation, but should be as limit.
Mirror surface structure 4 is passed to image module with the light beam that body 2 combines for the outside, and mirror surface structure 4 comprises a housing 41, an elastic body 42 (consulting Fig. 4), an optical layers 43 and a voltage-controlled element 44.In this example, though housing 41 is to have a column type surrounding wall 410 explanations, but its shape structure should be as limit, column type surrounding wall 410 defines a compression stroke 411, one first opening 412 and that is communicated with compression stroke 411 is formed at second opening 413 on the surrounding wall 410, elastic body 42 combines and seals first opening 412 so that a rubber frame 421 and housing 41 are airtight, elastic body 42 materials include but not limited to as natural rubber (NR); styrene-butadiene rubber (SBR); fourth rubber (NBR); ethylene propylene rubber (EPDM); butyl rubber (IIR); butadiene rubber (CR); polyurethane (PU) or silicon rubber (Q) etc.; optical layers 43 is located at elastic body 42 on the face of first opening 412; and optical layers 43 materials are reflecting material; as silver; chromium etc.; can be with coating; sputter; anodizing; modes such as evaporation, form one anti-(folding) and penetrate layer.Voltage-controlled element 44 is a pump, is connected with second opening 413, controls the force value of compression stroke 411 to borrow extraction gas mode.
Above-mentioned only is simple assembly introduction, and the detailed start principle of the present invention below is described in detail in detail.
Consult Fig. 4, the reflective coating that is coated with on elastic body 42 surfaces is earlier through design, preferably, coating density is then implemented according to result of experiment, all good reflecting effect can be arranged to reach under the different curve curvature, suppose this moment, force value in the compression stroke 411 and outside equate (an about atmospheric pressure), and through voltage-controlled element 44 effect, the force value in the compression stroke 411 are reduced, when for example being decreased to the working pressure of compression stroke 411 less than external pressure, because the external and internal pressure value differs, to make elastic body 42 and optical layers 43 be subjected to this pressure differential and produce deformation, cause the change of surperficial curvature, in like manner, when internal pressure also can make it distortion during greater than external pressure, as shown in Figure 5, elastic body 42 and optical layers 43 thickness change, certainly, the detail parameters corresponding relation that pressure difference value and thickness change needs to consider through calculating earlier, to reach best curve form, generally speaking less as thin part deformation quantity, thicker part deformation quantity is bigger.Whereby, instead (folding) can reach our desired curve form after penetrating the effect of layer process pressure differential, if user's minute surface summit is constant to the fixed distance on image module (for example CCD camera lens summit), just can reach the demand of rapid adjustment field range, and (meaning promptly needn't to adjust focal length, the variation of focal length is to be reached by the change of curve form, the curvature of the general minute surface of tradition is for fixing), as shown in Figure 6, for thickness does not change preceding field range, after reflectance coating thickness changes, as shown in Figure 7, field range also changes along with the variation of curved surface, what specify is, because the adjustment (for example zoomin/zoom out) of the general camera visual field and focal length all sees through the drive of small-sized actuator, but mirror surface structure of the present invention 4 should be when camera, can reduce the demand of an actuator, save cost and space, in addition, mirror surface structure 4 also can apply to other field that needs zoom or adjust the visual field, the rearview mirror of automobile for example can significantly lower the appearance at dead angle.
In sum, utilize mirror surface structure 4 of the present invention and image-taking device, be used for adjusting the curvature of specular surface by pressure differential, need not dismantle the focal length that can reach image module and the adjustment in the visual field, not only convenient, and when being applied to focusing or zoom in/zoom out, also can save the cost and the reduced volume space of actuator, more preferably, when being applied to rearview mirror, can reach the scope at no dead angle, the probability that the reduction traffic accident takes place by the change of curved surface.
The above person only is the preferred embodiments of the present invention, and when not limiting scope of the invention process with this, promptly the simple equivalent of doing according to content of the present invention generally changes and modifies, and all belongs in the scope that the present invention contains.
