The present Application for patent claims priority to and the benefit of Chinese Application No. 2022229498087, filed Sep. 27, 2023, and hereby expressly incorporated by reference herein as if fully set forth below in its entirety and for all applicable purposes.
The present disclosure relates to the technical field of cameras, and in particular, to a structure for controlling lens parameters.
At present, in the field of photography, photographers need to manually control the lens parameters to perform photography. This control method is not only troublesome but also cannot accurately adjust data or lens parameters by manual control.
For example, the prior art has disclosed an independent high-magnification visible light lens control device for photoelectric turntables (the application number is CN202021257237.5), which includes a supporting connecting rod, a motor rotating chamber, and a gear rotating chamber, wherein the bottom end of the supporting connecting rod is fixedly connected to the top of the motor rotating chamber through a fixing screw, two sides of the inner wall of the supporting connecting rod are fixedly connected to a rotating block and a fixed rotating block in turn from left to right, and one side of the supporting connecting rod is fixedly connected to a fixed supporting rod. This prior art relates to the technical field of lens control. The independent high-magnification visible light lens control device for photoelectric turntables enables the lens to rotate by 360 degrees in the horizontal direction through the components arranged in the motor rotating chamber, and enables the lens to rotate by 360 degrees in the vertical direction through the arrangement of the two sides of the inner wall of the supporting connecting rod. However, the control device cannot control some parameters such as follow focus and zoom of the lens.
The following presents a summary of one or more aspects of the present disclosure, in order to provide a basic understanding of such aspects. This summary is not an extensive overview of all contemplated features of the disclosure, and is intended neither to identify key or critical elements of all aspects of the disclosure nor to delineate the scope of any or all aspects of the disclosure. Its sole purpose is to present some concepts of one or more aspects of the disclosure in a form as a prelude to the more detailed description that is presented later.
In order to solve the above problems, the primary object of the present invention is to provide a lens control mechanism, which can control parameters (e.g., lens parameters) such as follow focus and zoom of the lens, such that the parameter adjustment is more convenient and more accurate.
Another object of the present invention is to provide a control device, which can control the camera and lens parameters.
In order to achieve the above objects, the technical schemes of the present invention are as follows.
A lens control mechanism includes a first control body, a driving assembly, and driving teeth for meshing with a lens, wherein the driving teeth are movably arranged on the first control body, the driving assembly is fixedly arranged on the first control body, the driving assembly is drivingly connected to the driving teeth, and the first control body is provided with a mounting position for mounting the lens control mechanism such that the driving teeth mesh with the lens. Specifically, the outer side of the external lens corresponding to the driving teeth is provided with teeth 31 that mesh with the driving teeth. After the mechanism is mounted through the mounting position, the driving teeth are engaged with the corresponding position of the lens, and the driving assembly drives the driving teeth to rotate, thereby driving the corresponding position of the lens to rotate, so as to achieve automatic control of parameters such as follow focus and zoom of the lens. The operation of the driving assembly may be controlled by providing a key on the mechanism, or by wired or wireless control through an external structure. All the above methods may be used. That is, through the structural design of the mechanism, the parameters such as follow focus and zoom of the lens can be automatically controlled. Compared with manual adjustment, the parameter adjustment of the lens is more accurate and convenient.
Further, the driving teeth are located at one end of the first control body, and the mounting position is a mounting hole located at the other end of the first control body. The driving teeth and the mounting holes are respectively arranged at the two ends of the first control body, such that the mechanism is more convenient to mount, and the mounting position is the mounting hole, which may be fixed on the external camera or a circular tube arranged on the bracket for mounting the external camera, such that the mounting of the mechanism can be achieved, and the mounting is more convenient.
Further, the first control body is movably provided with a first hand-twist assembly for locking an external circular tube in the mounting hole, and a front end of the first hand-twist assembly extends to a side edge of the mounting hole. The first hand-twist assembly locks the mechanism on the outer circular tube by twisting, which makes the mechanism more convenient to mount.
Further, the first control body is further provided with a first control key. The first control key can control the operation of the driving assembly.
A control device includes a lens control mechanism and a control handwheel mechanism wirelessly connected to an external camera, wherein the control handwheel mechanism is connected to the lens control mechanism, the control handwheel mechanism includes a second control body, a touch screen assembly for controlling the external camera or/and the lens control mechanism, and a handwheel assembly for controlling the external camera or/and the lens control mechanism, the touch screen assembly is fixedly arranged on the second control body, and the handwheel assembly is rotatably and movably arranged on the second control body. Specifically, the above “/” means “or”, the above control handwheel mechanism and the lens control mechanism may be connected by wires or wirelessly, and the specific implementation of the above wireless connection belongs to the prior art. Through the arrangement of the device, by the control handwheel mechanism, the driving assembly on the lens control mechanism can be controlled to automatically control parameters such as follow focus and zoom of the lens, and at the same time, the parameters on the external camera can be directly controlled by the control handwheel mechanism, that is, various parameters of the camera and the lens can be controlled by the control handwheel mechanism simultaneously, which is more convenient. The control handwheel mechanism is wirelessly connected to the external camera, such that the camera and lens parameters can be remotely controlled.
Further, the control handwheel mechanism is wirelessly connected to the lens control mechanism.
Further, the number of the lens control mechanisms is two or more (a first lens control mechanism and a second lens control mechanism), the first control body is provided with a plurality of first interfaces, the two lens control mechanisms are connected in series through the first interfaces, the second control body is provided with a second interface, and the control handwheel mechanism and the lens control mechanism are wired through the second interface and the first interfaces. The control handwheel mechanism may supply power to two lens mechanisms simultaneously.
Further, the handwheel assembly is arranged around the touch screen assembly. This arrangement makes the structural design of the control handwheel mechanism more reasonable, and makes the overall volume of the control handwheel mechanism smaller.
Further, the second control body is movably provided with a limit switch for limiting a rotation angle of the handwheel assembly.
Further, the second control body is further provided with a second key for controlling the external camera or/and the lens control mechanism.
Further, the second control body is further provided with a lever for controlling the lens control mechanism.
Further, the handwheel assembly and the touch screen assembly are located at one side of the second control body, the other side of the second control body is provided with a mounting groove, a first electronic contact pin is arranged in the mounting groove, a mounting assembly is detachably arranged in the mounting groove, the mounting assembly is electrically connected to the control handwheel mechanism through the first electronic contact pin, the mounting assembly is provided with a mounting position for detachably connecting an external device, and the mounting position is internally provided with a second electronic contact pin for electrically connecting with an external device.
The present invention has the advantages that through the structural design of the mechanism, the parameters such as follow focus and zoom of the lens can be automatically controlled. Compared with manual adjustment, the parameter adjustment of the lens is more accurate and convenient.
