Abstract

The invention provides a lens focusing mechanism comprising an elastic lens surface, a liquid storage chamber, a connecting pipe and a permeable membrane, wherein an accommodating chamber is defined in the elastic lens surface, and at least two liquids which are not mutually dissolved and have different refractive indexes are in the accommodating chamber; the liquid storage chamber is disposed onthe outer side of the elastic lens surface and communicated with the accommodating chamber; one end of the connecting pipe is communicated with the liquid storage chamber, and the other end of the connecting pipe is communicated with the accommodating chamber; and the permeable membrane is arranged between the connecting pipe and the accommodating chamber. According to the lens focusing mechanism,by utilizing the structure of combining the elastic lens surface, the liquid storage chamber, the connecting pipe and the permeable membrane, flexible focusing can be achieved, and the lens focusingmechanism has the advantages of having a wide focusing range, being convenient to use and facilitating processing and production.

Description

technical field [0001] The invention relates to the technical field of optical lenses, in particular to a lens focusing system. Background technique [0002] Existing zoom lenses are mainly used in optical lenses such as photography and photography. Motors are usually used to move the lens to change the position of the lens to achieve continuous zooming within the zoom range. It has the disadvantages of complex structure and high production cost. Not only that, but also has the disadvantages of The shortcomings of inconvenient use and difficult operation. Contents of the invention [0003] In view of this, the present invention provides a lens focusing system. [0004] In order to solve the problems of the technologies described above, the present invention adopts the following technical solutions: [0005] The lens focusing system according to an embodiment of the present invention includes: an elastic lens surface, a housing cavity is defined in the elastic lens surfac...
