Electric lifting pan-tilt head for roof camera
2011
The utility model discloses an electric lifting pan-tilt head for a roof camera, which comprises a driving motor (1), a transmission mechanism, a pan-tilt head box (2), a pan-tilt head base (3) and at least two screws (4). The top of the pan-tilt head box (2) is open; the pan-tilt head base (3) is capable of ascending and descending; the four corners of the open surface at the top of the pan-tilt head box (2) are provided with triangular plates (5); at least two opposite angles of the pan-tilt head base (3) are respectively provided with a screw hole (6); each screw perpendicularly penetrates through one screw hole, is connected with the screw hole in a threaded fit manner and supports the pan-tilt head base (3); a first bevel gear (7) is mounted fixedly at the lower end of each screw; the transmission mechanism is respectively connected with each first bevel gear in a matched manner so that each screw is capable of rotating synchronously; the driving motor (1) is connected with one first bevel gear in a meshed manner by the aid of a second bevel gear (8); and the screws drive the pan-tilt head base (3) to ascend and descend after the driving motor (1) drives each screw to rotate. The electric lifting pan-tilt head is capable of realizing electric lifting of the pan-tilt head base within a smaller stroke, and achieving the lifting function of the roof vehicular small camera.
