Abstract
A kind of automatic focusing structure, when needing to be focused video camera, by driving motor to drive one of gear to rotate, it is in rotate backward so as to which the gear of the rotation drives meshed gear, at the same time, two drive the rack of same side in mobile in the same direction in counter-rotational gear, so as to which sliding panel drives the CCD plates with imaging sensor to move, to realize automatic focus on, because rack pinion precision is high, stable drive, and without using decelerating motor, therefore, the focusing speed of video camera is fast, focusing accuracy is high, and energy consumption is low, the auto-focusing of this kind of video camera is simple in structure, cost is low, safeguard facility.
Description
Technical field
The present invention is intended to provide a kind of automatic focusing structure for video camera.
Background technology
Nowadays social, the application of video camera is more and more wider, and therefore, the work efficiency requirement to video camera is higher and higher, especially
It is the focusing function of video camera, and it is to move focusing lens by camera lens to realize, due to camera lens volume that current video camera, which focuses on,
Greatly, weight is big, and therefore, inertia is big in camera lens moving process, to avoid camera lens from can not stopping because inertia is big in moving process
On required position, DC speed-reducing need to be used to drive, however, camera lens translational speed, after deceleration, it will cause focus on speed
Degree is slow, and high energy consumption.
The content of the invention
A kind of the present invention is intended to provide automatic focusing structure that focusing speed is fast, precision is high and energy consumption is low.
A kind of automatic focusing structure of the present invention, including base, are respectively arranged with along the both sides in base length direction
Guide rod, base top are provided with the sliding seat with rectangular through holes, and sliding seat bottom both ends are respectively arranged with and corresponding sides guide rod
Matched guide groove, is provided with fixed plate on one end on sliding seat along its length, band image is provided with fixed plate and is passed
The CCD plates of sensor, are respectively arranged with rack on the both sides apparent surface of the rectangular through holes on sliding seat, are set at rectangular through holes
Two gears being meshed are equipped with, the wheel and rack of homonymy is meshed, and vertical fixing axle is additionally provided with the base, Gu
Dead axle is connected with the one of gear that can be rotated to it, and can pass through base by 1 bottom of base with respect to the shaft of base rotation,
Its upper part is connected firmly with another gear, and the output shaft for the driving motor that its underpart is rotated by shaft coupling with drive shaft connects firmly.
A kind of automatic focusing structure of the present invention, when needing to be focused video camera, by driving motor to drive
Dynamic one of gear rotates, so that it is in rotate backward that the gear of the rotation, which drives meshed gear, meanwhile, two are in
Counter-rotational gear drives the rack of same side in movement in the same direction, so that sliding panel is driven with imaging sensor
CCD plates move, with realize it is automatic focus on because rack pinion precision is high, stable drive, and without using decelerating motor,
Therefore, the focusing speed of video camera is fast, and focusing accuracy is high, and energy consumption is low, and the auto-focusing of this kind of video camera is simple in structure, cost
It is low, safeguard facility.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention.
Embodiment
A kind of automatic focusing structure, as shown in Figure 1, including base 1, is respectively arranged with along the both sides of 1 length direction of base
Guide rod 2, the top of base 1 are provided with the sliding seat 4 with rectangular through holes 3, and 4 bottom both ends of sliding seat are respectively arranged with and corresponding sides
2 matched guide groove of guide rod, is provided with fixed plate 5 on one end on sliding seat 4 along its length, is provided with fixed plate 5
CCD plates 6 with imaging sensor, are respectively arranged with rack 7 on the both sides apparent surface of the rectangular through holes 3 on sliding seat 4, long
Two gears being meshed 8 are provided with square through hole 3, the gear 8 of homonymy is meshed with rack 7, is also set up on the base 1
There is vertical fixing axle 11, fixing axle 11 is connected with the one of gear 8 that can be rotated to it, and can be rotated relative to base 1
Shaft 9 passes through base 1 by 1 bottom of base, and its upper part is connected firmly with another gear 8, and its underpart is turned by shaft coupling 12 and driving
The output shaft for the driving motor 10 that axis 9 rotates connects firmly.
The driving motor 10 is servomotor, by servomotor rotating to drive sliding seat 4 to move back and forth, servo
Motor working efficiency is high, and control accuracy is high.
Shaft 9 is connected by rolling bearing with base 1, so that shaft 9 can be rotated relative to base 1, is reduced therebetween
Frictional force, avoids the two relative motion and wears.
The guide groove diameter is equal with 2 diameter of guide rod, the two cooperation is even closer, sliding seat 4 is slided precision higher.
