Consult Fig. 2, be the first embodiment of the present invention, this support portion 20 is located in the inner space 11 of this holding part 10 with the structure of transparent ball; These first lens 30 are located in the inner space 11 of this holding part 10, its periphery is contacted with on the surface of this inner space 11 substantially, the centre of first face 31 of these first lens 30 contacts one first conduction fixed part 50 substantially, the periphery of this first conduction fixed part 50 is fixed in the first end 12 of this holding part 10, and these first lens 30 contact this support portion 20 with the centre of second face 32 substantially.
This second lens section 40 is to be located in the inner space 11 of this holding part 10, its periphery is contacted with on the surface of this inner space 11 substantially, the centre of first face 41 of these second lens 40 contacts one second conduction fixed part 60 substantially, the periphery of this second conduction fixed part 60 is fixed on the second end 13 of this holding part 10, second facial 42 these support portions 20 of contact of these second lens 40.
As shown in Figure 3, this holding part 10 is applied electric power, then action below producing on the holding part 10:
At first, suppose these holding part 10 axial shrinkage one preset distance D, first, second end 12,13 of this holding part 10 drives the displacements in the middle of its inner spaces 11 of this first, second conduction fixed part 50,60 respectively.
Have, first face 31 of 50 pairs of these first lens 30 of this first conduction fixed part is exerted pressure again, and the centre of second face 42 of these first lens 30 is supported by this support portion 20, thus produce curved transition (be assumed to be curvature and become big), and then change focal length.
As shown in Figure 7, when flexible zoom lens of the present invention is applied to camera, calculate by prior test, this holding part 10 is applied predetermined electric power, first, second lens 30,40 of may command change to predetermined curvature, and then produce zoom effect accurately, make camera take graceful photo.
In preferred embodiment of the present invention, this holding part 10 also can be one can reciprocating type mobile mechanism; This support portion 20, these first lens 30 and this second lens 40 all can be poly dimethyl oxosilane (Polydimethylsiloxane is called for short PDMS), can produce in a large number, reduce cost.This support portion 20 is a transparent ball, and this first conduction fixed part 50 and this second conduction fixed part 60 are all the electro-conductive glass of transparent conductor film shape, for example is tin indium oxide (Indium TinOxide is called for short ITO).
Consult Fig. 4 and Fig. 5, it is another embodiment of the present invention, still first lens 30 and second lens 40 are set in these holding part 10 inside, second face 32,42 of these first, second lens 30,40 is relative, this first conduction fixed part 50 is body in the form of a ring, and directly be shaped on the first end 12 of this holding part 10, and contact the periphery of first face 31 of these first lens 30; This second conduction fixed part 60 is body in the form of a ring also, and directly is shaped on the second end 13 of this holding part 10, and contacts the periphery of first face 41 of these second lens 40; In addition, this support portion 20 is body in the form of a ring generally, and contacts second face 32,42 of these first, second lens 30,40 simultaneously.
As shown in Figure 6, same, this holding part 10 is applied electric power, then action below producing on the holding part 10:
Suppose these holding part 10 axial shrinkage one preset distance D, first, second end 12,13 of this holding part 10 (drive respectively this first, second conduction fixed part 50,60) is toward its inner space 11 relative closings.
With the structure that slightly changes, control first, second lens 30,40 equally and change to predetermined curvature, and then produce zoom effect accurately.
And for changing holding part 10 into square tube or other cartridge types by cylinder; or; between each lens and support portion, add other transparent configurations (being assumed to be water liquid or other lens); or control the holding part 10 and effect or the like that produce distorting mirror flexible with inequality proportion easily full of beard and structural change, the category of neither disengaging this case protection.
The present invention has following advantage:
1. simple in structure.The present invention installs simple support portion in a holding part, first lens and second lens are positioned at respectively in the holding part again, finishes a flexible zoom lens, and structure is quite simple and exquisite.
2. simple focusing.The present invention is as long as apply predetermined power to holding part, and it is flexible to control this holding part, and holding part drives first, second lens and changes curvature, and then reaches Zoom effect, and action is rapidly simple.
3. be easy to produce so cost is low.Most of structure of control such as support portion of the present invention, first, second lens section zoom all can be manufactured by the poly dimethyl oxosilane, in a large number so cost is extremely low.
The above, it only is preferred embodiment of the present invention, be not that the present invention is done any pro forma restriction, every foundation technical spirit of the present invention all still belongs in the scope of technical solution of the present invention any simple modification, equivalent variations and modification that above embodiment did.
