Description
Technical field
The utility model relates to digital photography, shooting product device field, relates in particular to switching device of optical fiber and electromagnetic drive unit thereof that a kind of digitized video device for shooting is used.The digitized video device for shooting of using this switching device of optical fiber is equipped with optics pick-up lens, optics low pass filter (Optical Low Pass Filter usually, hereinafter to be referred as OLPF) and the electric charge lotus root close element (Charge Coupled Device, C D).This switching device of optical fiber is used for controlling the photograph light path that the optical filter with different filtering functions inserted or withdrawed from the digitized video device for shooting.
Background technology
Most of digitized video device for shooting all needs to satisfy the requirement of round-the-clock twenty four hours running.But since daytime with night light luminance obviously different, for providing phtographic lens required light amount, usually in the daytime or understand two groups of different optical filters of functions of use night.By day, light is stronger, the light amount that makes phtographic lens pick up easily is too high, cause the image of shooting bright excessively, unclear, the optical filter that uses this moment should be the energy that can remove the light that naked eyes can't see, and for example ultraviolet ray, infrared ray etc. make more suitable light and the image of phtographic lens acquisition.But at night, light ray energy is just not enough originally, and the optical filter that uses this moment then should not have the function of isolating invisible light, must increase the penetrability of light on the contrary, or has the effect of eliminating ghost.Therefore; the digitized video device for shooting of round-the-clock twenty four hours running; especially monitor etc.; its employed switching device of optical fiber; usually can set the unit that to change the working position; station a-b box for example is so that by day or the suitable optical filter of (the perhaps environment of light darkness) its function that can automatically switch at night.
At present, commercially available digitized video device for shooting has been standardized or standardization, and it only can design one group of switching device of optical fiber for manufacturer and be installed in this space voluntarily for switching device of optical fiber provides a narrow space.Known switching device of optical fiber, its structure are divided into two kinds usually.
The first utilizes electro-motor to be responsible for driving, finishes transmission with members such as gears.The shortcoming of this Mechanical Driven conversion regime is that volume is too huge, and because of limited space, the less electro-motor of output power only can be installed, so the speed of optical filter when moving is slower, the image that optical lens is picked up produces fuzzy or shadow in the optical filter moving process.
It two is to twine optical filter box with coil, and the magnetic force that cooperates magnet to produce reaches the purpose of switching optical filter.The shortcoming of this Electromagnetic Drive conversion regime is comparatively power consumption, also break down easily at low temperatures, no matter and this kind mode optical filter whether be in switch or the standby process in, all want the sustainable supply electric energy, cause power consumption higher.And when low temperature or humidity were higher, the resistance between member increased, and the acting force that coil and magnet can produce will be difficult to optical filter is moved.Moreover after repeatedly moving back and forth, the plain conductor that constitutes coil is broken easily, causes switch failure.
For above-mentioned second kind of type of drive, Chinese patent application number is that 200320127940.4 utility model patent discloses a kind of " the infrared filter automatic starting device of video camera ", it is used for taking in the daytime chromatic image, take the structure that black and white is made a video recording and start optical filtering automatically night, include filter supporter, optical filter magnetic coil groups, photoresistance, the optical filter balladeur train, infrared filter and optical filter, utilize the switch of photoresistance control optical filter magnetic coil groups, and the balladeur train that is equiped with infrared filter and optical filter can be moved up and down, use the light line traffic control, can control moving of infrared filter and optical filter automatically, reach the equal effect that can make a video recording of different luminosity systems.This technical scheme be by infrared filter and optical filter under the effect of magnetic coil, rely on balladeur train to slide up and down and carry out the camera lens conversion, therefore shared space is bigger, is difficult to realize miniaturization Design.
In addition, one has two kinds of 8mm * 8mm and 7mm * 7mm effective shooting size of at present common on the market monitor CCD, if adopt the type of drive of straight line reciprocation type, the round trip of its driving mechanism just can not be less than 17mm, under this situation, be easy to generate following problem: 1) precision is difficult to control product fraction defective height; 2) after whole video camera assembling finished, transporting in the process of video camera, the switching device of optical fiber of video camera inside influenced its structural behaviour because of impact endurance test shock easily, causes the user can not start this device effectively.
