Embodiment Construction

[0010] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0011] like figure 1 As shown, the object of the present invention is to provide a lens control mechanism, the control mechanism includes a lens 10, a motor 2 and a drive wheel 4 driven by the motor 2, the motor 2 is covered with a layer of casing 3, and the motor 2 The circular arc fixing bracket 1 is directly fixed on the lens 10 with the thumb screw 9, and the driving wheel 4 driven by the motor 2 meshes with the focusing wheel on the lens 10, and the gear module of the driving wheel 4 is connected to the focusing wheel on the lens 10. The modulus of the gears is the same, and the outer side of the rolling shaft connecting the driving wheel 4 and the motor 2 is provided with a bushing 7, and the bushing 7 is fixed by a fixing nut 8, and the inner opening of the fixing nut 8 is sequentially laid with a compression spring 6 and a gas...

Abstract

The invention discloses 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 motor is directly fixed on the On the lens, the drive wheel driven by the motor meshes with the focus wheel on the lens, and the gear modulus of the drive wheel is the same as that of the focus gear on the lens. The new type is simple and compact in structure and small in size. It controls the focus gear on the lens through a small motor and a driving wheel that can mesh with the focus gear on the lens. It has an overload protection function and will not damage 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...
