[0001] This application relates to the field of lens and camera adapter technology, specifically to an adapter structure for lens autofocus. Background Technology

[0002] A camera generally consists of a body and a lens. The lens and body are connected via a lens mount, through which the camera obtains the lens's parameters. A large number of original manufacturer lenses are available on the market, as well as third-party lenses. Therefore, adapters are commonly used to connect lenses and camera bodies. Adapters allow different brands of cameras and lenses to be connected to meet various photographic needs.

[0003] Currently, after the lens is mounted on the camera via an adapter, the focus ring on the outside of the manual lens needs to be rotated to adjust the physical distance between the lens elements and the sensor plane to achieve focus on different subjects. The photographer needs to observe the image in the viewfinder and press the shutter to take the picture after confirming that the subject is in focus.

[0004] However, most current adapters are purely mechanical structures that have an adapter function, but require the photographer to manually adjust the lens to focus, making their function relatively limited. Utility Model Content

[0040] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments, and the operational steps involved in each embodiment can also be rearranged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for clearly describing a particular embodiment and do not imply that they represent the necessary components and / or order.

[0041] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0042] In the market, lens 7 and camera body are typically connected via adapter rings. These adapter rings allow different brands of cameras 1 and lens 7 to be linked together to meet various photographic needs. Currently, after lens 7 is mounted on camera 1 via an adapter ring, the focus ring on the outside of the lens 7 needs to be rotated manually to adjust the physical distance between the lens group and the photosensitive plane, thus achieving focus on different subjects. The photographer needs to observe the image in the viewfinder and press the shutter to complete the shot once the subject is confirmed to be in focus. However, most current adapter rings are purely mechanical structures, possessing the conversion function, but requiring the photographer to manually adjust lens 7 for focusing, making their functionality relatively limited.

[0043] This application provides an adapter structure for lens autofocus, which can process and respond to data and commands transmitted by camera 1, and achieve autofocus of manual lens 7 through the phase focusing of the camera. It is easy to use and allows lenses 7 of different models or brands to be used on different cameras 1. The manual lens 7 adapter ring is an external component of camera 1 and does not increase the size of camera 1 itself.

[0044] Please refer to Figure 1 , Figure 2 and Figure 3 One embodiment provides an adapter structure for lens autofocus, comprising: an adapter ring body 2, with a first connecting part 21 and a second connecting part 22 at its two ends, the first connecting part 21 being used to match the mount of a camera 1, and the second connecting part 22 being used to match the mount of a lens 7; a plurality of first contacts 3 disposed on the first connecting part 21 for contacting the camera 1 and performing data communication; a drive assembly 4, including a drive part 43 and a transmission part 42, the drive part 43 being able to drive the transmission part 42 to rotate, the transmission part 42 engaging with the lens focusing ring 71 on the lens 7 to drive the lens to rotate; and a control module integrated into the adapter ring body 2, the control module being electrically connected to the first contacts 3 and the drive assembly 4, and being used to receive the focusing signal from the camera 1 and control the drive assembly 4, specifically controlling the drive part 43 to control the movement of the transmission part 42, thereby driving the lens 7 to rotate to simulate the autofocus function.

[0045] It is worth noting that the focus ring 71 of the lens can be a ring-shaped toothed structure of the lens 7 itself, or a ring-shaped toothed strip that is tied to the lens 7, such as a silicone toothed strip. The ring-shaped toothed strip supports quick replacement of different specifications of focus strips through the binding method, which can be adapted to a variety of lens 7 models, and can also be adapted to lens 7 without exposed tooth grooves, thus improving compatibility.

[0046] In this embodiment, please refer to Figure 2 and Figure 4 The camera 1 is equipped with an internal control module and a second contact 11, which may be, but is not limited to, a spring-loaded second contact 11. One end of the second contact 11 is electrically connected to the internal control module, and the other end is used to contact the first contact 3 to transmit the focus signal of the camera 1 to the control module. After the first connecting part 21 is connected to the camera 1, multiple first contacts 3 and corresponding second contacts 11 are in elastic contact. Through the first contacts 3, the second contacts 11 communicate with the camera 1. The camera 1 sends a focus signal (such as phase detection focus data) to the adapter ring through the first contacts 3. After the control module analyzes the focus signal of the camera 1, it controls the drive component 4, which drives the lens focus ring 71 to rotate through the engagement of the transmission part 42, so as to realize the automatic focus of the manual lens 7 without the need for manual adjustment by the user.

[0047] In this embodiment, the adapter ring body 2 can be made of lightweight metal material, such as aluminum alloy, with a hollow internal design to integrate the control module; the outer surface of the adapter ring body 2 can also be provided with anti-slip texture to facilitate user grip and installation.

[0048] In this embodiment, the first connecting part 21 and the second connecting part 22 at both ends of the adapter ring body 2 enable physical connection between cameras 1 and lenses 7 of different brands, adapting to cameras 1 and lenses 7 with different mounts. This solves the problem of the single function of traditional adapter rings. For example, the adapter ring body 2 can be used to enable autofocus for manual lenses by utilizing the phase detection autofocus of Sony cameras. The first connecting part 21 can be set to a commonly used mount structure according to the mount type of the camera 1, and the second connecting part 22 can also be set to a commonly used mount structure according to the mount type of the lens. For example, the adapter ring body can be, but is not limited to, a PL mount to E mount adapter, allowing PL mount lenses to be connected to E mount cameras. Or, for example, the adapter ring body can be an L mount to E mount adapter, allowing L mount lenses to be connected to E mount cameras, and so on.

[0049] Please refer to Figure 1 The adapter ring body 2 is provided with a conduit support 6. The conduit support 6 and the adapter ring body 2 are an integral or detachable structure, and the drive component 4 is installed on the conduit support 6.

[0050] For details, please refer to Figure 2 , Figure 3 and Figure 5In this embodiment, the guide tube support 6 includes a connecting part 61 and a connecting guide tube 62. The lower end of the connecting part 61 is detachably mounted on the adapter ring body 2. The upper end of the connecting part 61 extends to both sides and is symmetrically arranged, and the connecting guide tubes 62 are respectively installed thereon. There are two connecting guide tubes 62, and the connecting guide tubes 62 are arranged along the axis of the lens 7. One end of the connecting guide tube 62 is detachably mounted on the upper end of the connecting part 61, and the other end extends towards the optical axis of the lens 7 and is used to install the drive assembly 4. There are two drive assemblies 4, which are respectively installed on the two connecting guide tubes 62. The two drive assemblies 4 are respectively distributed on the opposite side of the two connecting guide tubes 62. The transmission part 42 of one drive assembly 4 is used to engage with the focusing ring 71 on the lens 7; the transmission part 42 of the other drive assembly 4 is used to engage with the aperture ring 72 on the lens 7 to drive the aperture ring 72 to rotate. Specifically, the lens aperture ring 72 can be a ring-shaped toothed structure on the lens 7 itself, or a ring-shaped toothed rack attached to the lens 7, such as a silicone toothed rack. The ring-shaped toothed rack allows for quick replacement of different specifications, adapting to various lens 7 models, including lenses 7 without exposed tooth grooves, thus improving compatibility. This design enables adjustment of the lens 7's focus and aperture. Furthermore, the communication between the lens 7 and the camera 1 regarding aperture values ​​allows the camera to more effectively use phase-detection autofocus to enable manual lenses to achieve autofocus.

[0051] In this embodiment, please refer to Figure 5 The lower end of the connecting part 61 can be screwed to the peripheral wall of the connecting ring body; the upper end of the connecting part 61 is set as a ring buckle, the connecting tube 62 is inserted into the ring buckle to select the position and locked with bolts, and the two drive components 4 can be installed on the two connecting tubes 62 at the same time. The torque output is increased by synchronous drive to ensure the stable rotation of the lens focusing ring.

[0052] For further details, please refer to... Figure 2 and Figure 5 The drive assembly 4 also includes a mounting frame 41. One end of the mounting frame 41 is provided with a ring buckle. The entire mounting frame 41 can be detachably mounted on the connecting conduit 62 through the ring buckle. The user can adjust the mounting position of the mounting frame 41 on the connecting conduit 62 according to the size of the lens 7.

[0053] In this embodiment, please refer to Figure 5 The drive unit 43 is a micro motor with a control circuit board. When the control circuit board is powered on, it drives the motor to rotate. The motor has its own output gear. The transmission unit 42 uses a transmission gear and a drive gear in combination. The transmission gear is rotatably installed inside the mounting frame 41 and simultaneously meshes with the output gear and drive gear of the motor. The drive gear is rotatably installed on the periphery of the mounting frame 41 and extends beyond the range of the mounting frame 41, directly meshing with the tooth groove on the outer edge of the lens focusing ring 71.

[0054] During operation, the motor drives the output gear to rotate, which in turn drives the transmission gear and the drive gear to rotate in sequence under meshing connection. This, in turn, drives the lens 7 to rotate through the meshing of the drive gear with the lens focusing ring 71. Automatic focusing of the lens can be achieved by adjusting the motor's motion parameters via the control circuit board. In this embodiment, the transmission gear is used to adjust the speed of the drive gear. In other embodiments, the transmission gear can also be a gear set, or the motor can directly drive the drive gear through the output gear.

[0055] Please refer to Figure 2 and Figure 6 Furthermore, the adapter structure of this application also includes a wireless communication module 23 integrated into the adapter ring body 2. The wireless communication module 23 is used to establish a communication connection with an external mobile terminal; the control module is configured to receive lens 7 parameter data through the wireless communication module 23.

[0056] In this embodiment, please refer to Figure 6 The wireless communication module 23 is either a Wi-Fi module or a Bluetooth chip module. The external mobile terminal is a mobile phone, tablet, computer, or other device. The user connects the mobile phone and the control module of the adapter structure through the wireless communication module. The user writes the parameters of different lenses 7 through the corresponding APP to realize data acquisition, so that the camera 1 can identify the lens parameters through the adapter ring body 2. During use, different lenses can be switched on the APP according to different lenses.

[0057] Furthermore, in this embodiment, the lens 7 parameter data may include, but is not limited to, the focal range, aperture range, etc. The data is input through a mobile terminal application and uploaded to the cloud server for backend storage or stored locally on the adapter body 2. The user uses the APP to put all the customer-calibrated data into the server backend, which is convenient for collecting lens 7 parameters later. For example, when the user changes the adapter ring, he / she can directly download the stored lens 7 parameters from the cloud without having to input them again.

[0058] Please refer to Figure 1 , Figure 3 and Figure 4In this embodiment, the adapter structure not only enables automatic focus tracking but also allows for manual parameter adjustment to enable automatic focus tracking of the lens 7. Specifically, the adapter structure further includes a side handle 8 and a power supply component 81 and a manual control module 82 disposed within the side handle 8. The side handle 8 is detachably mounted on the camera 1. The power supply component 81 and the manual control module 82 are electrically connected to the wiring section 24 to supply power to and control the drive component 4. The side handle 8 controls the drive component 4 through direct and indirect control. The manual control module 82 may include a dial, which the user can rotate to receive a signal from the manual control module 82. This signal from the side handle 8 can be sent to the drive component 4, causing the drive component 4 to rotate in response to the manual adjustment of the side handle 8. In some embodiments, the signal from the side handle 8 can be directly sent to the drive component 4. Alternatively, the signal from the side handle 8 can be sent to the control module of the adapter ring body 2. The control module responds to the manual focus control signal from the manual control module of the side handle 8 and sends the signal to the drive component 4. This configuration facilitates the control module's management of automatic and manual focus.

[0059] The adapter ring body 2 is equipped with a mode switching knob 5 electrically connected to the control module. The mode switching knob 5 is used to switch between autofocus mode and manual focus mode. In autofocus mode, the control module responds to the focus signal of the camera 1 and sends it to the drive component 4 so that the drive component 4 performs the corresponding action. The position information of the drive component 4 is then returned to the camera. In manual focus mode, the control module responds to the manual focus control signal of the hand control module 82 and sends it to the drive component 4 so that the drive component 4 performs the corresponding action to control the drive component 4 to achieve manual focus. The position information of the drive component 4 is then returned to the side handle 8.

[0060] Please refer to Figure 3 and Figure 4 The side handle 8 includes a handle portion 87 and a connecting plate 83. The handle portion 87 is a mounting housing, with the power supply assembly 81 and the hand control module 82 disposed within its inner cavity. The connecting plate 83 is detachably connected to the bottom of the camera 1. The handle portion 87 is detachably connected to the connecting plate 83, allowing the handle portion 87 to be positioned on the left or right side of the camera 1. A display module 84 is also mounted on the side handle 8, allowing the user to focus and take pictures by holding the side handle 8. Specifically, one end of the connecting plate 83 is detachably mounted to the side wall of the side handle 8 near its bottom using a 1 / 4-inch screw, and the other end is mounted to the bottom of the camera 1 using a 1 / 4-inch screw. The user can adjust the mounting position of the side handle 8 according to their usage habits, increasing the flexibility of accessory use.

[0061] In this embodiment, please refer to Figure 3 and Figure 4The adapter ring body 2 has a wiring section 24 on its side. The wiring section 24 has an input interface 241 and an output interface 242. The input interface 241 and the power supply component 81 of the side handle 8 are electrically connected through a first connecting line 85. The output interface 242 is connected to two drive components 4 through a second connecting line 86. Specifically, a circuit board is provided inside the side handle 8. The power supply component 81 inside the side handle 8 is electrically connected to the corresponding circuit board. A power output port is provided outside the side handle 8. The first connecting line 85 connects the input interface 241 and the power output interface on the side handle 8, thereby achieving electrical connection with the corresponding circuit board and supplying power to the drive components 4.

[0062] In autofocus mode, the control module responds to the focus signal from camera 1 and controls drive component 4 to automatically adjust the focus. In manual focus mode, the control module switches to the signal from manual control module 82, and transmits the manual focus signal to drive component 4 through the operation of physical knob 821 and / or button 822 for fine focus adjustment. Specifically, the manual focus signal can be transmitted to the control module, which further controls drive component 4 to focus.

[0063] Please refer to Figure 3 and Figure 4 The power supply assembly 81 includes a 14.8V lithium battery, which is built into the side handle 8. The first connecting line 85 connects the power output port and the input interface of the wiring part 24. The power supply provides high torque power to the drive assembly 4 through the boost circuit to support the focusing requirements of the large damping lens 7. The hand control module 82 is set as a physical knob 821 and / or button 822. For example, the user can manually adjust the physical knob 821 to adjust the rotation direction and speed of the transmission part 42.

[0064] In another embodiment, the data of different lenses 7 can also be stored in the storage module of the side handle 8 in advance. When in use, the side handle 8 transmits the data to the adapter ring body 2 through the wiring part 24 according to the requirements of the lens 7, and then transmits it to the camera 1 through the first contact point 3. The camera 1 understands the various parameters of the lens 7 brand machine through data parsing.

[0065] The adapter structure of this application can realize the autofocus function of the manual lens 7 through the communication and drive component 4 via the first contact 3; it is compatible with different mount lenses 7, supports direct / indirect engagement and cloud-based parameter management; it also has dual-mode operation, with autofocus improving efficiency and manual mode meeting professional creative needs; each part of the structure is modularly designed, and the guide tube support 6, side handle 8 and other detachable structures are easy to maintain and expand.
