Abstract
The utility model provides a high-definition digital and optical zoom lens. The high-definition digital and optical zoom lens comprises a front end fixing lens group, a zoom lens group, a compensating lens group and a back end fixing lens group which are arranged in a main cylinder of the lens, and a driving and adjusting device which is arranged in the main cylinder of the lens, connected with the zoom lens group and compensating lens group and used for driving the zoom lens group and the compensating lens group to move synchronously, wherein the driving and adjusting device is provided with a lead screw group transmitted by a driving motor, a flexible circuit board connected with the driving motor, and an image sensing circuit board connected with external control equipment; the zoom lens group is arranged at the front end of the lead screw group; and the compensating lens group is arranged at the back end of the lead screw group. The high-definition digital optical zoom lens is characterized in that one rod in a guide rod group is a lead screw, and the other rod is a polished rod. The high-definition digital optical zoom lens has the beneficial effects that as a zoom driving design of single lead screw and double screw thread transmission is adopted, the zoom synchronicity of the zoom lens group and the compensating lens group is improved, the view finding rate is increased, a view field is enlarged, and the high-definition digital optical zoom lens is suitable for the development of miniature lenses for reducing costs.
Description
Technical field
The utility model relates to a kind of zoom lens, especially relates to the digital Zoom optic lens of a kind of high definition.
Background technology
At present, varifocal optical system is that a kind of focal length changes and the motionless optical system of image planes maintenance within the specific limits.As far back as nineteen thirty,, require the motion picture negation of different picture sizes can show in the screen of same size, or the motion picture negation of same size can be shown in the screen of different size along with the development of film industry.In order to address these problems, the projection lens of the enlargement ratio continuous variable of seeking development.Zoom lens all uses the interval that changes between the lens combination to change the focal length of whole object lens at present.When the mobile lens group changes focal length, always to attend by moving of image planes, therefore to recompense to the mobile of image planes.The method of IMC mainly contains optical compensation method and mechanical compensation method.After nineteen sixty, along with the improvement of mechanical processing technique, the raising of cam processing technology, the mechanical compensation method is widely used.
Almost all adopt zoom lens in the telephotography at present; 16mm process photography camera lens has substituted trend, and 35mm film news record photography also gradually adopts zoom lens.Simultaneously, the compact zoom lens used of 135mm camera is also increasing on market.Zoom lens is widely used in TV, film, look in the distance and sciemtifec and technical sphere such as cinephotomicrography, also is used widely in aspects such as the communication in the cosmic space, range finding, guided missile test, rocket, moonscope.
And the digital Zoom optic lens of general high definition all is to be provided with the displacement movement that two drive motor and two leading screws come transmission variable focus lens package, offset lens group zoom.Complex structure so not only, inconvenient maintenance, and the synchronous effect of variable focus lens package, the displacement of offset lens group is poor.
The utility model content
The purpose of the utility model provides the digital Zoom optic lens of a kind of high definition, solves the asynchronous of variable focus lens package, the displacement of offset lens group, causes focus effect difference problem.
The utility model solves the technical scheme that its technical matters adopted: the digital Zoom optic lens of a kind of high definition; Be included in front end fixed lens group, variable focus lens package, offset lens group and the rear end fixed lens group that is provided with in the camera lens master tube and be arranged on to connect in the camera lens master tube and drive variable focus lens package and the synchronization-moving drive adjusting device of offset lens group; Described drive adjusting device is the leading screw group of drive motor transmission; Connect the flexible PCB of drive motor and the image sensing circuit board that connects external control devices; Described variable focus lens package is arranged on the front end of guide rod group; Described offset lens group is arranged on the rear end of guide rod group, it is characterized in that: in the described guide rod group wherein one for leading screw; Another root is a polished rod.
Further, the rear end of described leading screw is provided with 60 ° of standard threads that adaptive variable focus lens package moves, and at the front end of leading screw the major thread that adaptive variable focus lens package moves is set.
Concrete, the pitch of described major thread is between 0.5mm～2mm.
The beneficial effect of the utility model: owing to adopted the zoom drive design of monofilament bar, two screw thread transmissions; Improved the synchronism of variable focus lens package and offset lens group zoom; Increase the multiplying power of finding a view, increased the visual field, and adapt to the miniaturization camera lens development that reduces cost.
Below will combine accompanying drawing and embodiment, the utility model will be carried out comparatively detailed explanation.
Description of drawings
Fig. 1 is the organigram of the utility model.
Fig. 2 is the partial schematic diagram of Fig. 1.The signal screw structure.
Among the figure: 1. camera lens master tube, 2. front end fixed lens group, 3. variable focus lens package, 4. offset lens, 5. rear end fixed lens group, 6. flexible PCB, 7. leading screw, 8. polished rod, 9.60 ° of standard threads, 10. major thread, 11. drive motor.
Embodiment
Further, the rear end of described leading screw 7 is provided with 60 ° of standard threads 9 that adaptive variable focus lens package moves, and at the front end of leading screw 7 major thread 10 that adaptive variable focus lens package moves is set.
Concrete, the pitch of described major thread 10 is between 0.5mm～2mm.
Owing to adopted the zoom drive design of monofilament bar, two screw thread transmissions, improved the synchronism of variable focus lens package and offset lens group zoom, increase the multiplying power of finding a view, increased the visual field, and adapted to the miniaturization camera lens that reduces cost and develop.
Above embodiment describes the preferred implementation of the utility model; Be not that scope to the utility model limits; Under the prerequisite that does not break away from the utility model design spirit; Various distortion and improvement that the common engineering technical personnel in this area make the technical scheme of the utility model all should fall in the protection domain that claims of the utility model confirm.
The utility model does not relate to all identical with the prior art prior art that maybe can adopt of part to be realized.
