Shown in Fig. 9, embodiments provide a kind of big or middle picture camera lens and move axle and wave technology switching device, comprise base 10, camera adjustments device 20 and lens adjustment device 30.
Specifically, base 10 can be configured to platy structure form.Such as, in Fig. 1 example shown, the wider width of one end of base 10, because camera adjustments device 20 needs transverse shifting, so wider one end is convenient to install camera adjustments device 20.
Camera adjustments device 20 comprises the first sliding seat 21, camera support 22, first driving mechanism 23 and the second driving mechanism 24, first sliding seat 21 transversely can be arranged at one end of described base 10 slidably, and described first driving mechanism 23 transversely slides on described base 10 in order to drive described first sliding seat 21.Camera support 22 can vertically be arranged on described first sliding seat 21 slidably, and described second driving mechanism 24 longitudinally slides on described first sliding seat 21 in order to drive described camera support 22.
That is, the first sliding seat 21 transversely can horizontally slip on base 10, and the first driving mechanism 23 provides driving force for the first sliding seat 21, and the first sliding seat 21 can be driven laterally to horizontally slip on base 10.And camera support 22, on the one hand, because camera support 22 is arranged on sliding seat, so camera support 22 laterally can to horizontally slip with the first sliding seat 21 and mobile; On the other hand, camera support 22 can vertically slide up and down relative to the first sliding seat 21 itself, and that is to say, camera support 22 can slide up and down on the first sliding seat 21.So, when camera is fixed on camera support 22, side-to-side movement in the horizontal can be realized, move up and down on vertical.
Lens adjustment device 30 comprises the second sliding seat 301, the 3rd driving mechanism, rotation seat 308, four-wheel drive mechanism, rotary seat 314 and the 5th driving mechanism, second sliding seat 301 longitudinally can be arranged at the other end of described base 10 slidably, and described 3rd driving mechanism longitudinally slides on described base 10 in order to drive described second sliding seat 301.Rotation seat 308 can rotate along an axis of pitch and be arranged on described second sliding seat 301, and described four-wheel drive mechanism is in order to drive described rotation seat 308 in the transversely axis rotation of described second sliding seat 301.Rotary seat 314 can be arranged on described rotation seat 308 along a vertical axis rotationally, and described 5th driving mechanism is in order to drive the vertically axis rotation on described rotation seat 308 of described rotary seat 314.
That is, the second sliding seat 301 longitudinally can seesaw on base 10, and the 3rd driving mechanism then can provide driving force for the second sliding seat 301, longitudinally seesaws on base 10 to drive the second sliding seat 301.And rotation seat 308, on the one hand, because rotation seat 308 is arranged on the second sliding seat 301, so rotation seat 308 can the movement in the vertical with the longitudinal sliding motion of the second sliding seat 301.On the other hand, rotation seat 308 itself can transversely turn an angle by axis relative to the second sliding seat 301, namely can swing up and down.Corresponding, four-wheel drive mechanism then can provide driving force for rotation seat 308, to drive rotation seat 308 transversely axis rotation on the second sliding seat 301.For rotary seat 314, on the one hand, because rotary seat 314 is arranged on rotation seat 308, rotation seat 308 is arranged on again on sliding seat, and sliding seat can longitudinally slide, so rotary seat 314 together can move with sliding seat in the vertical with rotation seat 308.On the other hand, rotary seat 314 can on rotation seat 308 vertically axis rotate, that is to say and can horizontally rotate.Corresponding, the 5th driving mechanism then can provide driving for rotary seat 314, to drive rotary seat 314 vertically axis rotation on rotation seat 308.
In embody rule process, camera lens is only needed to fix on rotary seat 314 by corresponding retainer plate, camera being fixed on camera support 22, the first sliding seat 21, camera support 22, camera entirety can being driven to move to the left or to the right by rotating the first driving mechanism 23.And can drives camera support 22, camera entirety be moved up or down by rotation second driving mechanism 24.So, moving up and down of camera is achieved.
Meanwhile, the second sliding seat 301, rotation seat 308, rotary seat 314 and camera lens entirety can be driven movable by rotating the 3rd driving mechanism.Rotation seat 308, rotary seat 314 and camera lens lower swing on the whole can be driven by four-wheel drive mechanism.And rotary seat 314 and camera lens integral level can be driven to rotate by the 5th driving mechanism, so, achieve camera lens longitudinal sliding motion, tilted upward, horizontally rotate.
Corresponding, moved up and down by camera, can regulate focal plane with on the no longer same axis in the center of camera lens.And by the longitudinal sliding motion of camera lens, can focus, by camera lens tilted upward (i.e. pitching), can the visual angle etc. of adjustable lens.
Move axle according to big or middle picture camera lens provided by the invention and wave technology switching device, wherein, camera adjustments device 20, moving up and down of camera can be realized, and lens adjustment device 30 can longitudinal sliding motion, tilted upward, left-right rotation etc., so, the various actions of combining camera regulating device 20 and lens adjustment device 30, can be implemented in the process of taking pictures and carry out various technological adjustment, the depth of field such as realizing husky nurse law controls, realizing correcting perspective distortion by moving axle, realizing micro-landscape effect by focus adjustment.Meanwhile, structure of the present invention is simple, and volume is little, and the distance moved up and down is large, goes for the different camera lenses such as large, medium and small picture.
