[0002] With the continuous progress of society and the economy, people's demand for spiritual, cultural, and entertainment experiences is increasing, prompting more and more consumers to enter the field of photography. This trend has led photography enthusiasts and other groups to place increasingly higher demands on cameras and other image acquisition equipment in terms of performance, operation, and quality.

[0003] Currently, cameras on the market typically consist of two parts: the camera body and the lens. For ease of carrying and storage, the camera body has a bayonet mount with multiple latches; the lens also has a corresponding bayonet mount and matching latches (or protrusions). The interlocking of these two sets of latches allows for a detachable connection between the camera body and the lens. However, in actual use, the latches of existing lenses often cause a jamming or obstruction when docking with the camera body due to collisions between the latches, making the assembly and disassembly process less smooth and affecting the overall user experience. Utility Model Content

When the movable protrusion is screwed onto the camera, it is pushed by the camera jaws to move the movable protrusion away from the optical axis and engage with the camera body.

[0006] Optionally, the movable protrusion is initially flush with the outer edge of the bayonet body, and when the movable protrusion is screwed onto the camera body, it moves away from the optical axis and protrudes beyond the outer edge of the bayonet body.

[0007] Optionally, when the movable protrusion is screwed onto the camera body, it moves away from the optical axis and becomes flush with the fixed protrusion.

[0021] The bayonet provided in this application embodiment has at least the following beneficial effects: Compared with the prior art, the bayonet provided in this application embodiment, when attaching the lens to the camera body, has the movable protrusion and the fixed protrusion inserted into the corresponding notch of the camera body. When the movable protrusion is screwed onto the camera body, the camera jaws push the movable protrusion, causing it to move away from the optical axis and engage with the camera mount of the camera body, thus ensuring that the lens can be securely mounted on the camera body. In this way, during assembly, the movable protrusion is in its initial state, reducing collisions with the camera mount. After assembly, triggered by the push of the camera jaws, the movable protrusion moves and engages with the camera body. While ensuring reliable assembly of the lens and camera body, this reduces collisions and the feeling of jamming during assembly, improving the user experience.

[0034] The various specific technical features and embodiments described in the detailed implementation can be combined in any suitable manner without contradiction. For example, different implementation methods can be formed by combining different specific technical features / implementations / implementation methods. In order to avoid unnecessary repetition, the various possible combinations of the various specific technical features / implementations / implementation methods in this application will not be described separately.

[0035] Please refer to this as well. Figures 1 to 10 This application provides a bayonet 1, which can be installed as a component in a lens (e.g., Figure 8 As shown), it can also be installed as a component on an adapter ring (the adapter ring allows lenses of different mount 1 standards to be mounted on the camera body 2), and the mount 1 can be set to different mount 1 standards according to the camera. For ease of explanation, the embodiments and implementations of this application will be described in the case of the mount 1 being installed on a lens, but this is not a limitation of the embodiments of this application. The mount 1 of the embodiments of this application can also be applied to an adapter ring or other devices.

[0036] Please refer to this as well. Figures 1 to 3 The bayonet 1 includes a bayonet body 11, a fixed protrusion 114, and a movable protrusion 12. Both the fixed protrusion 114 and the movable protrusion 12 are connected to the bayonet body 11. The movable protrusion 12 can move along the optical axis (i.e., the height direction of the bayonet body 11, the Z-direction in the attached figure). See reference... Figures 7 to 10 When the lens equipped with the mount 1 of this embodiment is docked with the camera body 2, the camera body 2 has a camera mount 21 for docking the lens. The camera mount 21 is provided with a camera claw 211 and a mounting notch 212. The movable protrusion 12 and the fixed protrusion 114 of the mount 1 can be aligned with the mounting notch 212 on the camera mount 21 and extend into the mounting notch 212. During this process, since the movable protrusion 12 is closer to the optical axis direction than the fixed protrusion 114, that is, the movable protrusion 12 is in the initial state (hidden state), the movable protrusion 12 can effectively reduce the volume of the mount 1 and reduce direct collision with the camera mount 21. After the lens is docked and rotated for installation, the movable protrusion 12 will be pushed by the camera claw 211, so that the movable protrusion 12 moves away from the optical axis and engages with the camera body 2 (camera claw 211), thus completing the engagement of the lens with the camera body 2. This design, by utilizing the hidden movable protrusion 12, makes the structure of the mount 1 more compact, effectively reducing the size of the mount 1, reducing collisions when the lens is connected to the camera body 2, improving the smoothness of lens installation and removal, and effectively enhancing the user experience.

[0037] As one of the optional implementation methods of this application, please refer to Figure 4 and Figure 5In its initial state, the movable protrusion 12 is flush with the outer edge of the mount body 11. When the lens is mounted onto the camera body 2, that is, when the movable protrusion 12 is screwed onto the camera body 2, the movable protrusion 12 moves away from the optical axis and protrudes from the outer edge of the mount body 11. This design significantly reduces the collision between the movable protrusion 12 and the camera body 2 when the lens is docked with the camera body 2, improving the feel of lens mounting. When the lens is docked and rotated, the movable protrusion 12 moves and engages with the camera jaws 211 with the pushing action of the camera mount 21, ensuring the reliability of lens mounting.

[0038] Furthermore, as one optional implementation method of this application, please refer to... Figure 5 When the movable protrusion 12 is screwed onto the camera body 2, the movable protrusion 12 will move away from the optical axis and become flush with the fixed protrusion 114. In this way, the movable protrusion 12, after being pushed and triggered by the camera claw 211, can maintain a basically flush state with the outer edge of the fixed protrusion 114, allowing the movable protrusion 12 and the fixed protrusion 114 to better engage with the camera claw 211, ensuring the reliability of lens installation.

[0039] It should be noted that, in this embodiment, the flushness between the movable protrusion 12 and the fixed protrusion 114 means that the outermost edge of the movable protrusion 12 and the outermost edge of the fixed protrusion 114 are basically on the same virtual circle.

[0040] Furthermore, as one optional implementation method of this application, please refer to... Figures 1 to 3 The lens mount 1 also includes a drive assembly 13, which is connected to the main body 11. When the lens is docked and rotated with the camera body 2, the camera jaws 211 of the lens mount 21 abut against the drive assembly 13. As the lens rotates and is installed, the camera jaws 211 can push the drive assembly 13, causing the drive assembly 13 to push the movable protrusion 12 away from the optical axis until the movable protrusion 12 engages with the camera jaws 211. Conversely, when the lens is reversed for disassembly, as the camera jaws 211 are reversed, the drive assembly 13 releases its contact with the camera jaws 211. At this time, the drive assembly 13 will drive the movable protrusion 12 to reset, that is, drive the movable protrusion 12 to move closer to the optical axis. In this way, by using the drive assembly 13 to switch the rotational force of the camera jaws 211 to the reciprocating force of the movable protrusion 12, the reciprocating movement of the movable protrusion 12 can be achieved, which can effectively improve the compactness of the lens mount 1 structure and improve the feel of lens assembly and disassembly.

[0041] Furthermore, as one optional implementation method of this application, please refer to... Figure 2The drive component 13 protrudes from the outer edge of the mount body 11 and abuts against the camera jaw 211. When the lens is mounted on the camera body 2, the camera jaw 211 rotates along the outer edge of the mount body 11. At this time, because the drive component 13 protrudes from the outer edge of the mount body 11, the drive component 13 abuts against the camera jaw 211 and is driven by the camera jaw 211. Through the exposed drive component 13 design, the rotation of the lens during mounting can drive the drive component 13, thereby driving the movement of the movable protrusion 12. Lens mounting can be achieved without additional actions, which is highly efficient and reliable.

[0042] Specifically, as one of the optional embodiments of this application, when the bayonet 1 is screwed into the camera body 2, the camera claw 211 abuts against the drive assembly 13. At this time, the camera claw 211 will rotate around the circumference of the bayonet body 11 and push the drive assembly 13, so that the drive assembly 13 drives the movable protrusion 12 to move away from the optical axis. In this way, the force of the rotation of the camera claw 211 is used as the driving force of the drive assembly 13 to realize the movement of the movable protrusion 12, and the lens can be reliably installed without any extra actions.

[0043] Specifically, as one of the optional implementation methods of this application, please refer to Figures 1 to 4 The drive assembly 13 includes an abutment component 131 and an actuation component 132. The actuation component 132 is connected to the abutment component 131 and the movable protrusion 12. Specifically, a portion of the structure of the abutment component 131 is exposed on the outer edge of the mount body 11. When the lens is mounted on the camera body 211, the abutment component 131 abuts against the camera jaw 211 and transmits the rotational force of the camera jaw 211 to the connected actuation component 132. The actuation component 132 converts the circumferential force into a radial force, which acts on the movable protrusion 12, allowing the movable protrusion 12 to move away from the optical axis and ultimately engage with the camera jaw 211. Thus, through the cooperation of the abutment component 131 and the actuation component 132, the axial force of the camera jaw 211 is converted into a radial force acting on the movable protrusion 12 in a timely and efficient manner, enabling the camera jaw 211 to engage with the movable protrusion 12 and achieving reliable lens mounting.

[0044] Specifically, as one of the optional implementation methods of this application, please refer to Figure 2 and Figure 3The abutment component 131 includes a slider 1311 and a limiting member 1312. The slider 1311 is slidably connected to the bayonet body 11, and the limiting member 1312 is connected to the slider 1311. The end of the limiting member 1312 protrudes from the outer edge of the bayonet body 11 so that it can abut against the camera jaw 211. When the lens is rotated and installed, the limiting member 1312 abuts against the camera jaw 211 and pushes the slider 1311 to slide along the circumferential direction of the bayonet body 11.

[0045] Specifically, as one of the optional implementation methods of this application, please refer to Figure 2 and Figure 3 The bayonet body 11 has a limiting groove 115, and the end of the limiting member 1312 extends into the limiting groove 115 and protrudes from the outer edge of the bayonet body 11 so that the limiting member 1312 can abut against the camera claw 211.

[0046] In specific applications, the slider 1311 is located inside the main body 11 of the mount, and the limiting member 1312 can be detachably connected to the slider 1311 to facilitate the assembly of the abutment component 131. Through the cooperation of the limiting member 1312 and the limiting slide groove 115, the abutment with the camera claw 211 is achieved. This design makes the structure of the abutment component 131 more compact and improves the space utilization. On the other hand, the slider 1311 located inside the main body 11 of the mount will not directly collide with the camera claw 211 during the sliding process, which helps to improve the smoothness of lens rotation.

[0047] Furthermore, as one optional implementation method of this application, please refer to... Figure 3 and Figure 6 The main body 11 of the bayonet is provided with a sliding groove 117, which is arranged around the circumference of the main body 11. The bottom of the limiting member 1312 is provided with a first protrusion 1314, which extends into the sliding groove 117. When the sliding member 1311 is subjected to force and slides, it is restricted by the first protrusion 1314 and the sliding groove 117, and the sliding member 1311 slides along the sliding groove 117 to make the sliding of the sliding member 1311 more reliable.

[0048] Furthermore, as one optional implementation method of this application, please refer to... Figure 2 and Figure 3The limiting slide 115 is arranged adjacent to the fixed protrusion 114, and the limiting slide 115 is arranged along the fixed protrusion 114. When the lens is docked with the camera body 2, the camera claw 211 will first extend into the notch adjacent to the fixed protrusion 114, and will not collide with the limiting member 1312 in the limiting slide 115, which is conducive to improving the docking feel. At the same time, before the lens is installed on the camera body 2, the protruding fixed protrusion 114 can be used to hide and cover the limiting slide 115 and the limiting member 1312, reducing the entry of foreign objects into the inner side of the bayonet body 11 through the limiting slide 115, and ensuring the reliability of the bayonet 1.

[0049] Specifically, as one of the optional implementation methods of this application, please refer to Figure 3 and Figure 4 The actuating component 132 includes a swing member 1321 and a swing fastener 1322. The swing member 1321 is connected to the bayonet body 11 and the movable protrusion 12. Under the action of the abutment component 131, the swing member 1321 can swing circumferentially along the bayonet body 11. The swing fastener 1322 is connected to the swing member 1321 and is used to limit the swing range of the swing member 1321. In this way, by limiting the swing range of the swing member 1321 through the swing fastener 1322, the swing member 1321 can only move within a specific range. By using the reciprocating swing of the swing member 1321 to drive the reciprocating movement of the movable protrusion 12, the reliability of the movable protrusion 12 can be ensured.

[0050] Specifically, as one of the optional implementation methods of this application, please refer to Figure 4 and Figure 5 The swing member 1321 has a first groove 1323, and the movable protrusion 12 is slidably connected to the first groove 1323. The extension line of the length direction of the first groove 1323 intersects the extension line of the length direction of the swing member 1321. When the abutting component 131 applies force to the swinging component 1321, the swinging component 1321 swings from the starting position to the ending position. During this process, since the extension line of the length direction of the first slide groove 1323 intersects with the extension line of the length direction of the swinging component 1321, the movable protrusion 12 will slide along the direction of the first slide groove 1323, that is, the movable protrusion 12 will move away from the optical axis. Conversely, when the camera body 2 releases the trigger state of the camera body 2, the swinging component 1321 will swing from the ending position to the starting position. Driven by the swinging component 1321, the movable protrusion 12 will reset and move along the first slide groove 1323 towards the center of the claw body, so as to reduce the direct collision with the camera body 2 when the lens is disassembled and improve the feel of lens disassembly and assembly.

[0051] This design, utilizing the cooperative design of the first groove 1323 and the swing member 1321, enables the swing member 1321 to convert the force by means of this cooperative design, so that the force exerted by the swing member 1321 on the virtual circle in the circumferential direction is converted into a force in the direction of the optical axis. It has the characteristics of simple structure, reliability and high efficiency.

[0052] For example, the swing member 1321 can be a long strip with a certain curvature. The swing direction of the swing member 1321 is the circumferential direction of the virtual circle in which the swing member 1321 is located. The length direction of the first groove 1323 intersects the circumferential direction of the virtual circle. That is, the swing direction of the swing member 1321 is different from the movement direction of the movable protrusion 12.

[0053] As one of the optional implementation methods of this application, please refer to Figure 3 and Figure 4 The swing member 1321 also has a second sliding groove 1324, which is arranged along the length direction of the swing member 1321. The swing fastener 1322 is fixedly connected to the bayonet body 11 and slidably connected to the second sliding groove 1324. In this way, by utilizing the cooperation of the swing fastener 1322 and the second sliding groove 1324, the swing range of the swing member 1321 can be limited. That is, during the swinging process, the swing member 1321 will be restricted by the second sliding groove 1324 and the swing fastener 1322, and can only slide along the length direction of the second sliding groove 1324, and cannot detach from the bayonet body 11, thus ensuring the reliability of the swing member 1321.

[0054] Specifically, as one of the optional implementations of this embodiment, two second slide grooves 1324 and two swing fasteners 1322 can be provided. The two second slide grooves 1324 can be respectively provided at both ends of the swing member 1321, and the first slide groove 1323 is located between the two second slide grooves 1324.

[0055] For example, the second slide groove 1324 can be a long strip slide groove with a certain curvature, and the curvature of the second slide groove 1324 can be the same as or similar to the curvature of the swing member 1321. When the swing fastener 1322 is located at one end of the second slide groove 1324, the swing member 1321 is at the starting position. When the swing fastener 1322 is located at the other end of the second slide groove 1324, the swing member 1321 is at the ending position. That is, the positions of the two ends of the length of the second slide groove 1324 limit the starting position and the ending position of the swing member 1321.

[0056] Specifically, as one of the optional implementation methods of this application, please refer to Figures 2 to 4The drive assembly 13 also includes a reset component 133 for resetting the abutment component 131 and the actuation component 132. The reset component 133 is connected to the abutment component 131 and the actuation component 132. When the actuation component 132 is slid from the starting position to the ending position, it will drive the reset component 133, putting the reset component 133 into an energy-storing state. After the camera body 2 releases its contact with the abutment component 131, the reset component 133 in the energy-storing state will reset and release, driving the actuation component 132 and the abutment component 131 back to the starting position. At the same time, the actuation component 132 will drive the movable protrusion 12. In this way, through the cooperation of the reset component 133, the abutment component 131 and the actuation component 132, the movable protrusion 12 is reset, improving the feel of lens assembly and disassembly.

[0057] For example, the reset component 133 can be a spring. One end of the spring can be connected to the swing member 1321, and the other end of the spring can be connected to the slider 1311. The slider 1311 and the swing member 1321 can be connected by the spring. A second protrusion 1313 is provided on the side of the slider 1311 connected to the spring. The spring is sleeved on the second protrusion 1313. A receiving groove is formed on the side of the swing member 1321 facing the spring. The spring extends into the receiving groove and is connected to the swing member 1321. Specifically, in the initial state, the spring can be in a natural state (i.e., not stretched or compressed) or in a slightly compressed state. The compressed spring can act on the abutment component 131 and the actuation component 132 to keep the abutment component 131 and the actuation component 132 in the starting position, ensuring the stability of the movable protrusion 12.

[0058] Of course, in other embodiments, the reset component 133 can also be a spring or a miniature motor, etc.

[0059] As one of the optional implementation methods of this application, please refer to Figure 4 The angle α formed by the two ends of the movable protrusion 12 and the line connecting it to the optical axis is the same as the angle β formed by the two ends of the fixed protrusion 114 and the line connecting it to the optical axis.

[0063] For example, the mounting component 118 can be a bayonet screw, and the bayonet body 11 has a plurality of screw holes spaced apart, through which the bayonet screw can be connected to the lens body 3.

[0064] In other embodiments, the mounting component 118 may also be a snap-fit, adhesive, or threaded structure, etc.

[0065] Specifically, as one of the optional implementation methods of this embodiment, please refer to Figures 1 to 3 The movable protrusion 12 includes a snap-fit ​​portion 121 for extending out of the outer edge of the bayonet body 11 and a connecting portion 122 connected to the snap-fit ​​portion 121. The snap-fit ​​portion 121 can extend out of the outer side wall of the bayonet body 11. One end of the connecting portion 122 is connected to the snap-fit ​​portion 121, and the other end of the connecting portion 122 is connected to the first groove 1323 of the swing member 1321.

[0066] Specifically, the snap-fit ​​part 121 has an arc-shaped structure, and the snap-fit ​​part 121 can be a long strip structure with a certain curvature. The connecting part 122 can be an L-shaped structure to reduce the space occupied by the movable protrusion 12.

[0067] As one of the optional implementation methods in this embodiment, please refer to Figures 1 to 3 The main body 11 of the bayonet has a circular structure to facilitate its docking with the camera bayonet 21.

[0068] Specifically, as one of the optional embodiments of this example, the bayonet body 11 includes a main body 111, a bayonet part 112, and a mounting part 113. The bayonet part 112 is connected to the main body 111, and the mounting part 113 is connected to the bayonet part 112. The main body 111 can be used to connect with the lens body 3, thereby mounting the bayonet body 11 on the lens body 3. The mounting part 113 and the bayonet part 112 are used to accommodate the mounting movable protrusion 12 and the drive assembly 13, and the bayonet part 112 is used to dock with the camera bayonet 21.

[0069] More specifically, the main body 111 and the mounting part 113 have an annular structure, the bayonet part 112 has a cylindrical structure, the main body 111 is connected to the outside of the bayonet part 112 and close to the end face of the bayonet part 112, and the mounting part 113 is connected to the inside of the bayonet part 112. The main body 111, the mounting part 113 and the bayonet part 112 can be an integrally formed structure.

[0070] In specific applications, the specific structure, size, shape, etc. of the bayonet body 11 can be adaptively adjusted according to the specific situation of the camera body 2, and this embodiment does not impose any restrictions.

[0071] Specifically, as one of the optional implementation methods of this embodiment, please refer to Figure 4 The main body 111 of the bayonet body 11 is provided with a positioning groove 116. The positioning groove 116 is located on the side facing the camera body 2. When the lens with the bayonet 1 of this embodiment is installed on the camera body 2, after the lens is installed in place, the positioning pin of the camera body 2 (not shown in the figure) can extend into the positioning groove 116 to prevent the lens from accidentally rotating out.

[0072] Specifically, as one of the optional implementations of this embodiment, the outer side of the bayonet portion 112 of the bayonet body 11 is provided with an anti-rotation screw (not shown in the figure). The anti-rotation screw can play a limiting role during the lens installation and rotation process. By cooperating with the camera body 2, it can prevent the lens from rotating excessively and ensure the reliability of the lens.

[0073] As one of the optional implementation methods in this embodiment, please refer to Figure 4 The fixed protrusion 114 is connected to the bayonet body 11 and is spaced apart from the movable protrusion 12. The fixed protrusion 114 has a fixed position and structure relative to the movable protrusion 12. Through the cooperation of the fixed protrusion 114 and the movable protrusion 12, the fixed protrusion 114 has higher structural strength, which can improve the clamping strength between the lens and the camera body 2. At the same time, the movable protrusion 12 can improve the smoothness of the lens and the camera body 2 docking and improve the user experience.

[0074] Specifically, the fixing protrusion 114 protrudes from the outer edge of the bayonet body 11. The fixing protrusion 114 is disposed on the bayonet portion 112 of the bayonet body 11 and exposed outside the bayonet body 11 so as to engage with the camera claw 211.

[0075] In practical applications, the fixed protrusion 114 and the movable protrusion 12 of the bayonet 1 can be adapted to the actual camera bayonet 21. For example, when the camera bayonet 21 is equipped with four camera claws 211, the fixed protrusion 114 and the movable protrusion 12 of the bayonet 1 can be set in total to four. Among them, there can be three fixed protrusions 114 and one movable protrusion 12, or there can be two fixed protrusions 114 and two movable protrusions 12. The movable protrusions 12 and the fixed protrusions 114 can be set alternately.

[0076] The bayonet 1 provided in this embodiment allows the movable protrusion 12 and the fixed protrusion 114 to be inserted into the corresponding notches of the camera body 2 when the lens is attached to the camera body 2. When the movable protrusion 12 is screwed onto the camera body 2, the camera jaws 211 push the movable protrusion 12, causing it to move away from the optical axis and engage with the camera bayonet 21 of the camera body 2, thus ensuring a secure mount of the lens on the camera body 2. In this way, during assembly, the movable protrusion 12 is in its initial state, reducing collisions with the camera jaws 21. After assembly, triggered by the push of the camera jaws 211, the movable protrusion 12 moves and engages with the camera body 2. This ensures reliable lens-camera body assembly while reducing collisions and the feeling of jamming during assembly, improving the user experience.

[0077] This application embodiment also provides an adapter ring, including an adapter ring body and a bayonet 1 as described above, the bayonet 1 being connected to the adapter ring body.

[0078] The adapter ring provided in this application embodiment can be used between a lens and a camera body 2 to connect lens mounts 1 of different standards to the camera body 2. The movable protrusion 12 of the mount 1 can reduce collisions with the camera mount 21. After assembly, the movable protrusion 12 moves and engages with the camera body 2 under the push trigger of the camera claw 211. While ensuring reliable assembly between the lens and the camera body 2, it can reduce collisions and the feeling of jamming during assembly, thereby improving the user experience.

[0079] This application also provides a lens, please refer to... Figure 8 The lens includes a lens body 3 and a mount 1 as described above, with the mount 1 connected to the lens body 3.

[0080] Specifically, the lens body 3 may include a frame, a main board, a ribbon cable, a lens group, and an outer part. The outer part is fitted outside the frame, and there is a certain space between the frame and the outer part. The main board and the ribbon cable are installed in this space. The frame is roughly cylindrical in shape, and the lens group is located in the cavity inside the frame. The bayonet 1 is connected to the end of the frame.

[0081] The lens provided in this application embodiment utilizes the movable protrusion 12 of the mount 1 to reduce collisions with the camera mount 21. After assembly, the movable protrusion 12 moves and engages with the camera body 2 under the push trigger of the camera claw 211. While ensuring reliable assembly between the lens and the camera body 2, it can reduce collisions and the feeling of jamming during assembly, thereby improving the user experience.

[0082] This application also provides an image picking device, please refer to... Figure 9 and Figure 10 The image acquisition device includes a camera body 2 having a camera mount 21 and a lens as described above, wherein the lens is connected to the camera mount 21 of the camera body 2 via a mount 1.

[0083] The image pickup device provided in this application embodiment can reduce the collision between the lens and the camera body 2, improve the smoothness of assembly, and enhance the user experience.

[0084] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
