Patent Application
20240418238
The present Application for patent claims priority to and the benefit of pending Chinese Application No. 2023209401651, filed Jun. 13, 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 photographic auxiliary devices, in particular to a transmission belt for a lens.
At present, in the field of photography, there are some devices (such as lenses, etc.) whose parameters (e.g., focus, aperture) need to be adjusted through the rotation of an outer ring (e.g., control ring) of the device. Often the device provides anti-slip features (e.g., anti-slip straight lines) for rotating the outer ring. Some cameras have one or more external control rings that are designed with a textured surface or rubberized material that provides a better grip and reduces the risk of slipping. However, a typical outer ring cannot support the use of motors and other driving devices for the mechanical driving of the outer ring.
The following presents a summary of one or more implementations in order to provide a basic understanding of such implementations. This summary is not an extensive overview of all contemplated implementations and is intended to neither identify key or critical elements of all implementations nor delineate the scope of any or all implementations. Its sole purpose is to present some concepts of one or more implementations in a form as a prelude to the more detailed description that is presented later.
Therefore, the present disclosure aims to achieve the objective of connecting an external driving device by means of a composite transmission belt.
In view of the shortcomings mentioned above, the present disclosure provides a composite transmission belt, which can solve the limitation of the driving control of photographic devices. In order to achieve the above object, the present disclosure provides the following schemes:
In some aspects, a composite transmission belt includes a transmission part and a mounting part. The transmission part and the mounting part are connected (e.g., glued) into a whole unit. The transmission part can be made of a wear-resistant material, such as nylon or flexible metal. The transmission part is provided with a meshing area and an adjusting area, the meshing area is arranged above the transmission part and is composed of a plurality of same tooth profiles, and the meshing area can mesh with a driving device (e.g., a drive motor). The adjusting area is arranged at one end of the transmission part, and the adjusting area is composed of a groove and an adjusting meshing area. The meshing area can be flexibly deformed into a circle, the meshing area is on the outside of the circle, and an end of the meshing area is connected to the inside of the groove of the adjusting area and meshes with the adjusting meshing area inside the adjusting area, such that the composite transmission belt becomes circular.
The mounting part is composed of a non-slip and flexible material, such as silica gel. The mounting part is provided with an anti-slip texture, and can be attached to a device stably after being flexibly deformed into a circle.
The detailed description set forth below, in connection with the appended drawings, is intended as a description of various configurations and is not intended to represent the only configurations in which the concepts described herein may be practiced. The detailed description includes specific details for the purpose of providing a thorough understanding of the various concepts. However, these concepts may be practiced without these specific details. In some instances, well-known structures and components are shown in block diagram form in order to avoid obscuring such concepts.
The present disclosure will be described in conjunction with the accompanying drawings. As shown in
The transmission part 11 includes a meshing area 111, an adjusting meshing area 112, and a groove 113 (slot). The meshing area 111 includes a plurality of protruding elements (e.g., teeth with the same profile), and the meshing area 111 can be flexibly deformed (e.g., bent) into a circle (e.g., as a loop around a lens as shown in
In some aspects, the mounting area 12 includes a flexible area 121 and an anti-slip area 122. The anti-slip area is arranged at the bottom (as shown in
As shown in
In some aspects, the present disclosure provides a transmission belt that comprises a transmission part and a mounting part. The transmission part can be attached (e.g., glued) on an upper end of the mounting part. The transmission part can be composed of a wear-resistant material, such as nylon or flexible metal. The transmission part can be provided with a first meshing area and an adjusting area. The first meshing area is arranged above the transmission part and comprises a plurality of teeth, and the first meshing area can be used to mesh with a driving device. The adjusting area can be arranged at one end of the transmission part, and the adjusting area comprises a groove and an adjusting meshing area. The first meshing area can be flexibly deformed into a circle, the first meshing area is on the outside of the circle, and a portion of the first meshing area is connected to the inside of the groove of the adjusting area and meshes with the adjusting meshing area inside the adjusting area, such that the transmission belt becomes circular. The mounting part can be composed of a non-slip and flexible material, such as silica gel. The mounting part can be provided with an anti-slip texture, and can be attached to the driving device stably after being flexibly deformed into a circle.
In some aspects, a tooth type of the first meshing area can be an involute tooth type or a circular arc tooth type. In some aspects, the transmission belt can be deformable into a driving ring with an adjusting diameter. In some aspects, the transmission belt can include two materials. The transmission part can have wear resistance and lubrication properties. The mounting part can have flexibility and anti-skid properties.
In some aspects, a transmission belt for a lens includes: a transmission part comprising a meshing area; a mounting part connected to an end of the transmission part; and an adjusting part on the mounting part and forming a slot between the adjusting part and the mounting part. The transmission part can be bendable to be installed in the slot between the mounting part and the adjusting part. The transmission part can include a meshing area configured to mesh with the adjusting part. The meshing area can include a plurality of teeth configured to mesh with the corresponding teeth of a driving device (e.g., drive motor) of the lens. The adjusting part can include a plurality of teeth configured to mesh with a portion of the meshing area of the transmission part in the slot. The mounting part can include a non-slip and flexible material. The mounting part can be provided with an anti-slip texture on a side facing the lens.
In some aspects, the transmission part can include a wear-resistant material selected from the group consisting of nylon or flexible metal. In some aspects, the transmission belt can be composed of two materials. For example, the transmission part includes a material with wear resistance and lubrication properties, and the mounting part includes a material with flexibility and anti-skid properties.
In some aspects, a method of using a transmission belt on a lens is provided. The method attaches a transmission belt around a control ring of a lens. The transmission belt includes: a transmission part comprising a first meshing area; a mounting part connected to an end of the transmission part; and an adjusting part on the mounting part, and forming a slot between the adjusting part and the mounting part. The transmission part is wrapped around the lens to be installed in the slot between the mounting part and the adjusting part. The first meshing area comprises a plurality of teeth configured to mesh with the corresponding teeth of a driving device of the lens. The adjusting part comprises a plurality of teeth configured to mesh with the teeth on a portion of the first meshing area of the transmission part in the slot. The mounting part comprises a non-slip and flexible material. The mounting part is provided with an anti-slip texture on a side facing the lens.
In some aspects, the method bends the transmission part to form a loop around the control ring, a first portion of the transmission part overlapping a second portion of the transmission part. In some aspects, the method adjusts a position of the transmission part inside the slot to adjust the diameter of the loop formed by the transmission part around the control ring.
