Abstract: The present disclosure provides a novel pan-tilt structure for a camera of an UAV, comprising: a camera chip mounting seat, a steering mechanism, a housing, an output shaft, and a motor component, a PCBA circuit board, a speed reduction device and a position detection assembly which are all mounted in the housing; the steering mechanism is rotatably mounted on a steering mechanism mounting seat; the output shaft is located above the housing extending with a push rod; the steering mechanism connected to the push rod of the output shaft; the camera chip mounting seat is mounted at an end of the steering mechanism away from the steering mechanism mounting seat. The present disclosure realizes the miniaturization of a servo, the pan-tilt provided by the present disclosure is higher in rotation stability, more diversified in rotation angle, smaller in size, easy to mount and low in cost, and shoots clear pictures.

Abstract: The present disclosure relates to the field of servos, and in particular to a high-precision miniature servo with a new variable reluctance and improved motor positioning. Compared with conventional variable reluctances, the variable reluctance of the present disclosure has a longer service life, is lower in cost and is easier to machine. The motor component is directly assembled on the housing, so that the cost and space are saved, and the difficulty in mounting and positioning a miniature motor is mainly solved. A motor brush piece and the Ball element are directly machined on a PCBA circuit board, so that the problem on the difficulty and cost control of the conventional machining technology is solved.
