Abstract
The utility model discloses an autofocus camera. The autofocus camera mainly comprises a base, guide rods which are fixedly arranged on both sides of the base, a motor which is arranged on the base, sliders which are movably connected with the guide rods through clamping grooves, a fixation frame which is fixedly connected with the sliders, a CCD plate which is connected with the fixation frame, a front end cover which is arranged at the front end of the CCD plate, a camera lens which is arranged on the front end cover, a middle casing which is used for loading the base, a rear end cover which is arranged at the rear end of the middle casing, and a tail plate separation blade which is arranged in the rear end cover. Focus is realized by using the method that the camera moves the position of the CCD plate. Due to small volume and small mass inertia, the autofocus camera is driven by the linear stepping motor. The focus speed is fast and the accuracy is high. The computer control plate is used to perform an autofocus function. The long-focus potential zoom lens is used, and the lens does not move. The motor drives the sliders. The sliders are connected with the CCD plate. An image sensor on the CCD plate is driven, so that focus is accurate and the time is shortened.
Description
Technical field
The utility model relates to a kind of automatic-focusing camera.
Background technology
Existing camera review imageing sensor is for being fixed on housing, and the image focusing function is that dependence lens moving focusing lens group realizes, because of eyeglass not only volume and quality large, inertia is high, and generally adopts DC speed-reducing to drive, and causes focusing speed slow, precision is low, and it is high to consume energy.
Summary of the invention
Technical problem to be solved in the utility model is to provide that a kind of volume is little, and mass inertia is little, and focusing speed is fast, a kind of automatic-focusing camera that precision is high.
the utility model is achieved through the following technical solutions: a kind of automatic-focusing camera, mainly comprise base, and be fixedly installed on the guide rod of base both sides, and be arranged on motor on base, reach the slide block that is flexibly connected by draw-in groove and guide rod, and the fixed mount that is fixedly connected with slide block, and the CCD plate that is connected with fixed mount, and be arranged on the front end housing of CCD front edge of board, and be arranged on pick-up lens on front end housing, and for the mesochite that loads base, and be arranged on the rear end cap of mesochite rear end, and be arranged on tailgate catch in rear end cap, the mutual assembly connection of described front end housing and mesochite.
As technical scheme preferably, described motor is linear stepping motor, makes its speed when focusing on faster, and precision is higher.
As technical scheme preferably, described CCD plate is built-in with imageing sensor, electric machine rotation, thus the band movable slider moves forward and backward along guide rod, and slide block drives the CCD plate again and moves, and namely imageing sensor moves forward and backward, thereby makes focusing more accurate, and the time also shortens dramatically.
As technical scheme preferably, described draw-in groove diameter and guide rod equal diameters coordinate it between the two more tight, and increase useful life.
The beneficial effects of the utility model are: the method that adopts video camera to move the CCD Board position realizes focusing on, because volume is little, mass inertia is little, the employing linear stepping motor drives, and focusing speed is fast, and precision is high, and adopt computer control panel to carry out auto-focus function, the long-focus motorized zoom lens, eyeglass is motionless, the driven by motor slide block, slide block is connected with the CCD plate, thereby drive the imageing sensor on the CCD plate, thereby make focusing more accurate, the time also shortens dramatically.
Description of drawings
In order to be easy to explanation, the utility model is done to describe in detail by following specific embodiment and accompanying drawing.
Fig. 1 is the blast structural representation of the utility model automatic-focusing camera;
Fig. 2 is the combination schematic diagram of the utility model automatic-focusing camera.
Embodiment
shown in seeing figures.1.and.2, a kind of automatic-focusing camera of the present utility model, mainly comprise base 8, and be fixedly installed on the guide rod 7 of base 8 both sides, and be arranged on motor 6 on base 8, and by the slide block 5 of draw-in groove 12 with guide rod 7 flexible connections, and the fixed mount 4 that is fixedly connected with slide block 5, and the CCD plate 3 that is connected with fixed mount 4, and be arranged on the front end housing 2 of CCD plate 3 front ends, and be arranged on pick-up lens 1 on front end housing 2, and for the mesochite 9 that loads base 8, and be arranged on the rear end cap 10 of mesochite 9 rear ends, and be arranged on tailgate catch 11 in rear end cap 10, described front end housing 2 and the mutual assembly connection of mesochite 9.
Its operation principle is: motor 6 rotates, thereby band movable slider 5 moves forward and backward along guide rod 7, slide block 5 drives CCD plate 3 again and moves, again because being provided with imageing sensor (not shown) in CCD plate 3, thereby make focusing more accurate, time also shortens dramatically, and need not to rely on lens moving focusing lens group to realize focusing on again.
Wherein, described motor 6 is linear stepping motor, makes its speed when focusing on faster, and precision is higher.
Described CCD plate 3 is built-in with imageing sensor (not shown), and motor 6 rotates, thereby band movable slider 5 moves forward and backward along guide rod 7, slide block 5 drives CCD plate 3 again and moves, be that imageing sensor (not shown) moves forward and backward, thereby make focusing more accurate, the time also shortens dramatically.
Described draw-in groove 12 diameters and guide rod 7 equal diameters coordinate it between the two more tight, and increase useful life.
The above be only embodiment of the present utility model, but protection range of the present utility model is not limited to this, and any variation or replacement of expecting without creative work is within all should being encompassed in protection range of the present utility model.Therefore, protection range of the present utility model should be as the criterion with the protection range that claims were limited.
