When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0037] See also Figure 1 As shown, the present application proposes a lens assembly 100. The lens assembly 100 includes a lens body and an interactive interface 20; the lens body includes a bayonet 10 for connecting to a camera body, and the bayonet 10 and the camera body work together to form a seal at the connection; the interactive interface 20 is arranged on the lens body and is located at the same end as the bayonet 10; wherein, when the lens body is connected to the camera body through the bayonet 10, the interactive interface 20 is sealed to the inner side of the lens body.

[0038] In the technical solution of the present application, the interactive interface 20 includes a data exchange interface and / or a charging interface.

[0039] Understandably, in the process of updating the lens driver, it is usually necessary to visit the official website of the lens manufacturer or related software platform to download and install the latest driver. After the driver is downloaded, the lens can be connected to a computer or other smart device through the data exchange interface of the setting, and then the driver can be updated and installed. In this process, the data exchange interface plays the role of connecting and transmitting data, making the update process more efficient and convenient. The lens has a built-in driving power supply, and in some long-term shooting or outdoor shooting scenes, the user can charge the lens in time through the charging interface to ensure the continuous operation of the device.

[0040] Therefore, the data exchange interface and the charging interface are conventional interface settings in the lens assembly 100. The technical solution of the present application transfers the data exchange interface and the charging interface on the lens to the end of the lens body where the bayonet 10 is provided, rather than the side of the lens body, so that during the use of the lens, the above interfaces can be sealed to the inner side of the lens body based on the sealing of the connection between the lens body and the camera body, thereby preventing the above interfaces from being damaged by circuits due to exposure to water, especially in the application scenarios of outdoor operations and underwater photography, providing consumers with a safer and more reliable photography experience.

[0041] Among them, the data exchange interface and / or charging interface can be an interface type such as a Micro USB interface, a USB Type-C interface and a Lightning interface, which can support functions such as high-speed data transmission and high-power charging.

[0042] See also Figure 1 As shown, in some embodiments, the bayonet 10 includes a metal ring 110 , and the interaction interface 20 is opened on the metal ring 110 .

[0043] The metal ring 110 enhances the structural strength of the bayonet 10 , so that when the lens is connected to the camera body through the bayonet 10 to form an image pickup device, the connection between the lens and the camera body can be more stable, thereby improving the durability of the entire connection.

[0044] In this embodiment, the interactive interface 20 is provided on the metal ring 110, so that the interface and the bayonet 10 form a whole, further enhancing the stability and reliability of the connection. In addition, the material properties of the metal ring 110 also provide good protection for the interactive interface 20 thereon, which can effectively prevent the interface from being damaged or functioning incorrectly due to external factors.

[0045] Furthermore, when there are multiple interactive interfaces 20, multiple interactive interfaces 20 can be opened along the metal ring 110 based on actual use requirements. In some other embodiments, the interactive interface 20 can also be opened on other components of the lens body to ensure that the interactive interface 20 can be sealed after the lens body and the camera body are assembled.

[0046] In some embodiments, the mount 10 includes one of an E mount, a DL mount, a Z mount, an RF mount, a PL mount, an L mount, an EF mount, an F mount, an A mount, a K mount, and an X mount. These mounts are common mounting interfaces for stably connecting the lens 100 to the camera body, and users can select them based on actual conditions.

[0047] Furthermore, a flexible seal 30 and / or a waterproof structure may be provided along the outer periphery of the metal ring 110 on the bayonet 10 to form a seal with the camera body to the inner side of the lens body, thereby enhancing the sealing effect of the connection between the lens body and the camera body, effectively preventing the intrusion of external substances such as moisture and dust, and ensuring the stability and reliability of the lens body in harsh environments.

[0048] Specifically, the flexible seal 30 is usually made of an elastic material. For example, the flexible seal 30 can be a sealing gasket, which can fit tightly against the camera body to form a seal, thereby improving the waterproof and dustproof capabilities of the device. The waterproof structure can be designed with specific grooves or protrusions on the outer periphery of the bayonet 10, so that it can fit closely with the corresponding part of the camera body, thereby maintaining an excellent sealing effect and ensuring the normal operation of the image pickup device.

[0049] In some embodiments, the lens body further includes a waterproof cover (not shown in the drawings) configured corresponding to the interactive interface 20 , and the waterproof cover is used to close the interactive interface 20 .

[0050] In this embodiment, the main function of the waterproof cover is to seal the interactive interface 20 when the lens is not assembled with the camera body, thereby preventing external substances such as moisture and dust from entering the device through the interface, thereby enhancing the waterproof and dustproof capabilities of the device and extending the service life of the device.

[0051] The waterproof cover is usually made of a material and color that matches the metal ring 110 of the bayonet 10 to maintain the overall aesthetics. When in use, the waterproof cover can be inserted into the interactive interface 20, so that the user can easily open or close the interactive interface 20 to perform data transmission, charging or other interactive operations. When the waterproof cover is not in use, it should be properly kept.

[0052] See also Figure 2 As shown, in some embodiments, the lens body also includes an outer frame skeleton 40, a bayonet support 50 and an appearance part 60; the bayonet support 50 is installed on the outer frame skeleton 40, and the bayonet 10 is installed on the bayonet support 50; the appearance part 60 is covered on the periphery of the outer frame skeleton 40, the bayonet support 50 and the bayonet 10, and forms a detachable connection with the bayonet support 50.

[0053] Among them, the outer frame skeleton 40, as an important component of the lens, surrounds and protects the optical part of the lens, and can provide the necessary support and stability for the lens, and can also be used to install various lens accessories. Furthermore, the technical solution of the present application is based on the outer frame skeleton 40 to set the bayonet support 50. Generally speaking, the outer frame skeleton 40 is similar to a long cylindrical structure. The bayonet support 50 is set at the end of the outer frame skeleton 40 for connecting the camera body. The bayonet support 50 corresponds to the cylindrical port of the outer frame skeleton 40, that is, a ring-shaped setting. The bayonet support 50 can be used to install the bayonet 10.

[0054] The design and manufacturing quality of the exterior parts 60 have a great impact on the overall appearance and texture of the lens. A good exterior part 60 can make the lens look more exquisite and high-end, meeting the needs of some professional or high-end users. At the same time, the exterior parts 60 can also increase the anti-slip and anti-fingerprint properties of the lens through special coatings, coatings and other technologies, thereby improving the user experience. Therefore, in the manufacture of lenses, the design and manufacture of the exterior parts 60 is also one of the very important links.

[0055] The appearance part 60 in this embodiment is covered on the periphery of the outer frame skeleton 40, the bayonet support part 50 and the bayonet 10. When installed, a detachable connection is formed between the appearance part 60 and the bayonet support part 50, and only a connection is formed between the bayonet support part 50, thereby reducing the relevant amount of installation of the appearance part 60. Compared with the traditional installation method of the appearance part 60, after the lens is connected to the camera body through the bayonet 10 and the lens image quality is adjusted to meet the requirements, the appearance part 60 can be installed without the need to disassemble the bayonet 10. Therefore, the operation steps are reduced by transferring the installation object of the appearance part 60, thereby ensuring the continuous stability of the image quality.

[0056] See also Figure 2-Figure 4 As shown, in some embodiments, a limited locking structure is provided between the inner side wall of the appearance member 60 and the bayonet support member 50, and the appearance member 60 and the bayonet support member 50 are connected through the limited locking structure. The limited locking structure can enhance the connection stability between the appearance member and the bayonet support member 50, thereby improving the structural strength of the entire lens assembly 100.

[0057] In a specific embodiment, the limiting locking structure includes a snap-fitting groove 61, a snap-fitting block 51, a first locking hole 62 and a second locking hole 52; the snap-fitting groove 61 is arranged on the inner side wall of the appearance part 60, and an avoidance groove is opened on the side wall of the snap-fitting groove 61; the snap-fitting block 51 is arranged on the peripheral side of the bayonet support part 50 corresponding to the snap-fitting groove 61; the first locking hole 62 is arranged on the side wall of the appearance part 60; the second locking hole 52 is arranged on the bayonet support part 50 corresponding to the first locking hole 62; wherein, during the assembly process of the appearance part 60, the snap-fitting block 51 enters the snap-fitting groove 61 through the avoidance groove 611, and after rotating the appearance part 60, the snap-fitting block 51 is embedded in the snap-fitting groove 61 and the first locking hole 62 and the second locking hole 52 can be locked by screws.

[0058] In this embodiment, the locking groove 61 cooperates with the locking block 51 to achieve the movement limit between the appearance part 60 and the bayonet support 10; the first locking hole 62 cooperates with the second locking hole 52 to fasten the appearance part 60 and the bayonet support 50 to improve the connection stability.

[0059] Specifically, a snap-fit ​​groove 61 is provided on the inner side wall of the appearance part 60, and an avoidance groove is provided on the side wall thereof. This provides a channel for the entry of the snap-fit ​​block 51, ensuring that the snap-fit ​​block 51 can be smoothly engaged in the snap-fit ​​groove 61. During the assembly process, the appearance part 60 moves toward the outer frame skeleton 40 (bayonet support member 50), and the snap-fit ​​block 51 smoothly enters the snap-fit ​​groove 61 through the avoidance groove 611, and achieves preliminary positioning and fixation after the appearance part 60 is rotated. Then, based on the setting of the first locking hole 62 and the second locking hole 52, after the appearance part 60 is rotated, the snap-fit ​​block 51 can be completely engaged in the snap-fit ​​groove 61, and the first locking hole 62 and the second locking hole 52 can also be accurately aligned. At this time, the two locking holes are locked by screws or other fasteners, thereby achieving a firm connection between the appearance part 60 and the bayonet support member 50.

[0060] It can be understood that, in the process of the appearance member 60 moving toward the outer frame skeleton 40, the avoidance groove 611 needs to be aligned with the snap block 51 so that the snap block 51 can further enter the snap groove 61. A method of aligning the avoidance groove 611 with the snap block 51 is: when not aligned, the user can continuously apply a force to move the appearance member 60 toward the outer frame skeleton 40, and at the same time drive the appearance member 60 to rotate. In this process, if the snap block 51 is aligned with the avoidance groove 611, then under the action of the force, the snap block 51 can move along the avoidance groove 611 and finally enter the snap groove 61. At this time, the snap block 51 may also be separated from the snap groove 61, causing the appearance member 60 to separate from the bayonet support member 50. Therefore, after the snap block 51 enters the snap groove 61, the appearance member 60 needs to be further rotated so that the snap block 51 is embedded between the opposite side walls of the snap groove 61, and the appearance member 60 and the bayonet support member 50 are initially connected.

[0061] This limit locking structure is not only simple in structure and easy to operate, but also has a firm connection, stable and reliable. It can effectively prevent the loosening and misalignment between the appearance part 60 and the bayonet support part 50, ensuring the overall performance and stability of the lens assembly 100. At the same time, this structure is also easy to disassemble and repair, improving the maintainability of the equipment.
