Abstract
The utility model discloses a miniature camera tripod head which comprises a casing and a translucent cover. The utility model is characterized in that the utility model also comprises a horizontal rotary mechanism and a vertical rotary mechanism, wherein the horizontal rotary mechanism comprises an outer connecting bridge, a horizontal step speed reducing motor and a shaft connector; the vertical rotary mechanism comprises an inner connecting bridge, a vertical step speed reducing motor, a camera fixing rotary plate, a mandrel and a bearing. A camera can be driven by the horizontal step speed reducing motor to rotate in a horizontal direction, and the camera can be driven by the vertical step speed reducing motor to rotate along the mandrel.
Description
The utility model relates to a kind of a kind of novel miniature rotary head of the necessary electromechanical integration of ball-shaped camera that is used for closed-circuit TV monitoring system.
In the design of modern closed-circuit TV monitoring system, vidicon camera transfers back to guard monitor center with the image that is absorbed through video line as the front end of system, thereby has realized security personnel's electronization, save human and material resources greatly, greatly improved the efficient of safety precaution.But traditional vidicon camera as the front end of supervisory system the rotary head that must join, rotating speed is too slow, 6 ° of-24 °/S, and suitable, the counterclockwise 360 ° of rotations continuously of the level that can not realize, vertically can not arrive 90 °, so just cause vidicon camera when obtaining image, to produce " blind area " inevitably, be easy to generate the generation that causes unsafe factor owing to the imperfection of functions of the equipments.
The purpose of this utility model is exactly in order to overcome the above problems, a kind of spherical camera rotary head is provided, can accomplish to drive camera lens substantially horizontal up time meter or nearly counterclockwise 360 ° of rotations continuously, the Vertical direction per second can rotate nearly 90 °, it is whole to make camera lens can contain its place guarded region, and making supervisory system become one does not have " blind area " or " blind area " less safety and protection system.
The utility model realizes that the scheme of above-mentioned purpose is: a kind of miniature video camera machine head, comprise outer cover, transparent cover, and it is characterized in that; Also comprise horizontal rotary mechanism and vertical rotating machinery, described horizontal rotary mechanism comprises outer cross structure, horizontal stepping gear motor, shaft joint, and described vertical rotating machinery comprises interior cross structure, vertical stepping gear motor, vidicon camera fixedly flap, mandrel, bearing; Described outer cross structure is fixed on the extraneous supporter, and horizontal stepping gear motor just is fixed on the outer cross structure, and its running shaft vertically downward; Interior cross structure is a U type support, is connected in by shaft joint on the running shaft of horizontal stepping gear motor, can rotate in the horizontal direction under horizontal stepping gear motor drives; The outside of cross structure in vertical deceleration stepper motor is fixed in, vidicon camera fixedly flap by bearing fixing on the mandrel of interior cross structure inboard, and can drive lower edge mandrel rotation at vertical deceleration stepper motor.
Adopt the beneficial effect of above scheme: utilize said mechanism, cross structure and then drive vidicon camera rotation in the horizontal direction in can driving under the driving of horizontal stepper motor, fixedly flap and then drive vidicon camera rotate in vertical plane to drive vidicon camera under the driving of vertical stepper motor.Synthesizing of both direction motion, can realize the full visual angle scanning of motor, substantially dead zone-eliminating.Adopt the stepping gear motor, but the gear reduction driving mechanism of economization heaviness can further be realized miniaturization.
Fig. 1 is the utility model miniature video camera machine head front schematic view (part is analysed and observe).
Fig. 2 is the utility model miniature video camera machine head side schematic view.
Also the utility model will be further described in conjunction with the accompanying drawings below by specific embodiment.
See Fig. 1,2, shown in the miniature video camera machine head comprise outer cover 30, transparent cover 20 and horizontal rotary mechanism and vertical rotating machinery, described horizontal rotary mechanism comprises outer cross structure 1, horizontal stepping gear motor 2, shaft joint 3, and described vertical rotating machinery comprises interior cross structure 4, vertical stepping gear motor 5, vidicon camera fixedly flap 7, mandrel 6, bearing 8; Described outer cross structure 1 is fixed on the extraneous supporter, and horizontal stepping gear motor 2 just is fixed on the outer cross structure 1, and its running shaft vertically downward; Interior cross structure 4 is a U type support, is connected in by shaft joint 3 on the running shaft of horizontal stepping gear motor 2, can rotate in the horizontal direction under horizontal stepping gear motor 2 drives; The outside of cross structure 4 in vertical deceleration stepper motor 5 is fixed in, vidicon camera is in fixedly flap 7 is fixed in by bearing 8 on the mandrel 6 of cross structure 4 inboards (mandrel 6 two ends extend into vidicon camera fixedly in the hole of flap 7 both sides), and can drive 6 rotations of lower edge mandrels at vertical deceleration stepper motor 5.
Described shaft joint 3 adopts screw to be connected with interior cross structure 4.Transparent cover 20 can be a translucent body.
When horizontal stepper motor 2 drives shaft joint 3, (supporter is motionless with respect to ground generally on the extraneous supporter such as ceiling board because stepping gear motor 2 is fixed on by outer cross structure 1, but exception is arranged also, during as monitored passenger in elevator, in high-grade bus, it is that relative elevator and car body are motionless), thereby cross structure 4 clockwise in driving, back and forth rotation (as the infinite place device, rotatable nearly 360 °) counterclockwise, horizontally rotates thereby drive vidicon camera 10 interlocks.
When vertical stepping gear motor 5 actuated camera when fixedly flap 7 rotates because the effect of the limit stoper on the interior cross structure 4, thereby realize vidicon camera fixedly flap drive 90 ° in vidicon camera counterclockwise, back and forth rotate clockwise.
This cradle head structure is simple, and is novel, and volume is tiny, and good concealment is desirable safety apparatus.Can be widely used in places such as bank, market, elevator, coach, station, urban road crossing.
