Problems solved by technology

[0002] At present, there are many lens servos that we can see, but there are many problems, the structure is too complicated, and there is no overload protection function. The semi-servo lens refers to the zoom function that can only automatically control the camera lens, while the focus and aperture can only Manual control
For remote control or when there is no operator on site, remote control cannot be achieved with a semi-servo lens

Abstract

The invention discloses a lens control mechanism including a lens, a motor, and a driving wheel driven by the motor. A casing sleeves the motor, the motor is directly fixed on the lens through an arc fixing support in cooperation with a manual screw, the driving wheel driven by the motor is engaged with the focusing gear on the lens, and the modulus of the driving wheel gear is same to that of the focusing gear on the lens. The lens control mechanism is simple and compact in structure and small in size, the focusing gear on the lens is controlled by the miniature motor and the driving wheel in engagement with the focusing gear on the lens; and moreover, the lens control mechanism has an overloading protection function and has no damage to the lens.

Description

technical field [0001] The invention relates to the field of photographic equipment, in particular to a lens control mechanism. Background technique [0002] At present, there are many lens servos that we can see, but there are many problems. The structure is too complicated and there is no overload protection function. The semi-servo lens refers to the zoom function that can only automatically control the camera lens, while the focus and aperture can only Manual control. For remote control or when there is no operator on site, remote control cannot be achieved with a semi-servo lens. Contents of the invention [0003] The purpose of the present invention is to provide a lens control mechanism. [0004] The purpose of the present invention can be achieved through the following technical solutions: [0005] A lens control mechanism. The control mechanism includes a lens, a motor, and a driving wheel driven by the motor. The motor is covered with a layer of casing. The mo...
