As shown in Figure 1 and Figure 2, the camera lens filter plate switching device of video camera, it comprises:
One housing 10, it has stationary shaft 12, the central authorities of housing 10 are provided with through hole 11, the both sides up and down of through hole 11 are respectively arranged with the arcuate guide bone 15,16 that exceeds through hole 10 planes, this guiding bone 15,16 is used to guide optical filter rocker 20 swing on 10 of the housings again, also has two screw mounting holes 13,14 on the housing 10;
One optical filter rocker 20, be provided with circular rotation hole 21, oval-shaped articulated column 22, limited block 25, optical filter mounting hole 24 and through hole 23, wherein, the stationary shaft 12 of the position of opening of rotation hole 21 and described housing 10 is corresponding, be used for the described stationary shaft 12 of suit, articulated column 22 is positioned at the top of optical filter rocker 20, limited block 25 is positioned at the bottom of optical filter rocker 20, the through hole of offering on the size of optical filter mounting hole 24 and through hole 23 and the housing 10 11 big or small suitable, optical filter rocker 20 can be at the arcuate guide bone 15 of housing 10 under the effect of power, stationary shaft 12 reciprocally swingings of 16 guiding lower edge housing 10, through hole 23 on the rocker and optical filter mounting hole 24 be centered close to can with swinging track that 11 centers of through hole on the housing overlap on, when optical filter rocker 20 was made reciprocally swinging, two guiding bones on the housing 10 played the friction that reduces between optical filter rocker 20 and the housing 10;
One infrared fileter 30, this infrared fileter 30 is installed in the optical filter mounting hole 24;
One position-limited rack 40, these position-limited rack 40 integral body are arcuate structure, arch upward in its middle part, form an activity space, the limited block 25 of described optical filter rocker 20 can rotate in this activity space, the end of position-limited rack 40 is provided with two retaining blocks 43,44, be used to stop the rotational angle of limited block 25, make the optical filter center can aim at housing through-hole 11, the end of position-limited rack 40 also has two screws and installs 41,42, this screw mounting hole 41, screw mounting hole 13 on 42 position of opening and the housing 10,14 are in the opposite position place, by screw position-limited rack 40 are fixed on the housing 10;
One freeze mode electromagnet 50, the one end is provided with catch bar 51, catch bar 51 can be when magnet coil flows through the different directions electric current, produce forward or adhesive of stepping back or release movement, behind the coil deenergization, still remain on adhesive or release conditions, the front end of catch bar 51 has oval hinge hole 52, the oval articulated column 22 of these ellipse hinge hole 52 suit optical filter rockers 20, be hinged with articulated column 22, and catch bar 51 to optical filter rocker 20 application of forces, is swung around the stationary shaft 12 of housing 10 to drive optical filter rocker 20 in motion process.
Installation process of the present utility model is as follows: at first the rotation hole 21 of the optical filtering frame 20 that optical filter 30 is housed is enclosed within on the stationary shaft 12 of housing 10, again position-limited rack 40 on the limited block 25 of optical filter rocker 20, position-limited rack 40 is fixed on two mounting holes 13,14 of housing 10 by two mounting holes 41,42 with screw.Then, the oval hinge hole 52 on the catch bars 51 in the freeze mode electromagnet 50 is being overlapped articulated column 22 on the optical filter rocker 20, be fixed on the housing 10 with key screw freeze mode electromagnet 50.So just, finish the assembling of the camera lens filter plate switching device of this video camera, its assembly drawing as shown in Figure 2.
As shown in Figure 3, when freeze mode electromagnet 50 flows into direction that ports 54 flow out and flows through electric current with port 53, catch bar 51 moves right (shown in arrow among the figure) under magneticaction, and drive the articulated column 22 of optical filter rockers 20 by oval hinge hole 52, make optical filter rocker 20 clockwise rotate (shown in arrow among the figure) around the stationary shaft on the housing 10 12, because the resistance shelves of the 43 pairs of limited blocks 25 of retaining block on the position-limited rack 40 make infrared fileter 30 aim at housing center through hole 11.
As shown in Figure 4, and the direction that flows into port 53 outflow port 54 when freeze mode electromagnet 50 is when flowing through electric current, owing to produce magnetic force with aforementioned opposite polarity, catch bar 51 is to left movement (shown in arrow among the figure), and drive the articulated column 22 of optical filter rockers 20 by oval hinge hole 52, make optical filter rocker 20 rotate counterclockwise optical filter 30 and move apart center through hole 11 (shown in arrow among the figure) on the housing around the stationary shaft on the housing 10 12, because the resistance shelves of the 44 pairs of limited blocks 25 of retaining block on the position-limited rack 40 make through hole 23 aim at housing center through hole 11.
When image sensor current ambient brightness of living in is converted to light dark corresponding two on different directions electric current and being applied on the freeze mode magnet coil port 53,54, can realize that optical filter changes automatically, reach and take chromatic image daytime, take black-and-white image evening under infrared illumination.
As shown in Figure 5, the magnetic field M1 that permanent magnetism 56 is produced forms magnetic loops by iron-clad 57 and catch bar 51, and the suction that catch bar 51 is produced is bigger than the elastic force of spring 55, therefore, catch bar 51 is held bottom at iron-clad 57.
As shown in Figure 6, when coil 58 passes through electric current, suppose that direction of current is to go into from port 54 from port 53, the magnetic field M2 direction that is produced is opposite with the magnetosonic M1 direction of permanent magnetism 56, and then two magnetic force are cancelled each other, and at this moment spring 55 is just extrapolated catch bar 51.
As shown in Figure 7, after coil 58 stops to flow through electric current, the magnetic field M1 that only surplus permanent magnetism produces, but because this moment, catch bar 51 had suitable distance apart from iron-clad 57 bottoms, a little less than when M1 produces the suction inhaled to the iron-clad bottom than the adhesive stationary state to catch bar 51 many, and the elastic force that produces than spring 55 is little, so catch bar 51 will rest on the release stationary state that limited block stops.
As shown in Figure 8, when coil 58 passes through electric current, and direction of current is for to go into from port 53 from port 54, the magnetic field M3 direction that is produced is identical with the magnetic field M1 direction of permanent magnetism 56, then two magnetic force additions, and the elastic force that produces greater than spring 55, at this moment catch bar 51 by two magnetic force make a concerted effort inhale to the bottom of iron-clad 57, until colliding with the bottom and stopping.
After coil 58 stopped to flow through electric current, electromagnet was in the described adhesive stationary state of Fig. 5 again.
