Description
Technical field
The utility model relates to auto iris manufacturing technology field.
Background technology
Aperture is an important device on the camera lens, and it is mounted in, and control arrives the big or small device of sensor light through camera lens on the camera lens; The aperture of installing on the existing camera lens generally is divided into manual iris and auto iris; Manual iris is the size through diaphragm aperture in the manual adjustment aperture; Auto iris is to change diaphragm aperture size in the aperture through the extraneous light of photoresistance induction automatically by micromachine; But at present on the market auto iris can not manual operation, can not satisfy the requirement of some customized customer.
The utility model content
The technical matters that the utility model will solve provides a kind of auto iris, can regulate the size of diaphragm aperture in the aperture automatically, and also enable manual is regulated the size of diaphragm aperture in the aperture, satisfies the demand of some customized customer.
For achieving the above object, the technical scheme of the utility model is: a kind of auto iris comprises housing, diaphragm; The middle part of housing is provided with light hole; The rear portion of housing is provided with bonnet, and diaphragm is made up of two anti-dazzling screens that can move in opposite directions and be installed in the housing, and a side of housing is equipped with step motor; The driving shaft of step motor stretches in the housing and is connected with a connecting rod that has two ends, and the afterbody of two anti-dazzling screens is connected with two ends of said connecting rod.
Further, described connecting rod is connected with the driving shaft of step motor through a gear, reliability and assembly performance that the driving shaft of raising step motor is connected with connecting rod.
The utility model is owing to two anti-dazzling screens of diaphragm are driven by step motor; Step motor can conveniently be controlled its action through software; Can be provided with by the action of the automatic control step motor of photoresistance or by the action that manually comes the control step motor through peripheral hardware software and photoresistance; Therefore the utility model can be regulated the size of diaphragm aperture in the aperture automatically, and also enable manual is regulated the size of diaphragm aperture in the aperture, satisfies the demand of some customized customer.
Description of drawings
Fig. 1 is the utility model diaphragm open mode rear view;
Fig. 2 is the side view of Fig. 1;
Fig. 3 is that the utility model is removed bonnet diaphragm open mode rear view;
Fig. 4 is that the utility model is removed bonnet diaphragm closed condition rear view.
Embodiment
Below in conjunction with accompanying drawing and concrete embodiment the utility model is done further explain.
Fig. 1 is to shown in Figure 3, and a kind of auto iris comprises housing 1, diaphragm 2; The middle part of housing 1 is provided with light hole 11; The rear portion of housing 1 is provided with bonnet 12, and diaphragm 2 is made up of two anti-dazzling screens 21,22 that can move in opposite directions and be installed in the housing, and a side of housing 1 is equipped with step motor 3; The driving shaft 31 of step motor 3 stretches in the housing 1 and is connected with a connecting rod 4 that has two ends 41,42, and the afterbody of two anti-dazzling screens 21,22 is connected with two ends 41,42 of said connecting rod 4.
Described connecting rod 4 also can be connected with the driving shaft 31 of step motor 3 through a gear 5.
Fig. 3 shows that further drivening rod 4 was rotated counterclockwise when step motor 3 was rotated counterclockwise, and the end 41 of connecting rod 4 drives anti-dazzling screen 21 and moves to left, and the end 42 of connecting rod 4 drives anti-dazzling screen 22 and moves to right, and diaphragm 2 is all opened, and luminous flux is maximum.
Fig. 4 shows that further drivening rod 4 turned clockwise when step motor 3 turned clockwise, and the end 41 of connecting rod 4 drives anti-dazzling screen 21 and moves to right, and the end 42 of connecting rod 4 drives anti-dazzling screen 22 and moves to left, diaphragm 2 Close Alls, and light can not be through the light hole 11 of housing 1.
Because the anti-dazzling screen the 21, the 22nd of diaphragm 2, drive by step motor 3, just can realize that like cooperation step motor 3 is control automatically or manual control through the control device of peripheral hardware through photoresistance and software.
The above only is preferred embodiment of the utility model, and the change that those skilled in the art does to be equal to by claim all falls into the protection domain of this case.
Claims (2)
