Description

Technical Field

[0001] This application belongs to the field of photographic technology, and more specifically, relates to a bayonet, adapter ring, lens, and image pickup device. Background Technology

[0002] With the continuous development of society and economy, many consumers have entered the field of photography, and the requirements of photography enthusiasts and other consumer groups for cameras and other image acquisition devices are constantly rising.

[0003] Existing cameras generally consist of a camera body and a lens. To facilitate carrying or storing the camera, the camera body has a camera mount with multiple latches. The lens also has a mount with multiple latches. The two sets of latches work together to achieve a detachable connection between the camera body and the lens. However, when the latches of existing lenses are connected to the camera body, they are prone to collisions, and there is often a feeling of sticking when assembling or disassembling them, which affects the user experience. Summary of the Invention

[0004] The purpose of this application is to provide a bayonet mount, adapter ring, lens, and image pickup device to solve the technical problems in the prior art where the jaw components are prone to collision with the camera body's jaws and there is a jamming sensation when they are docked.

[0010] The movable jaw is connected to the main body of the bayonet. When the movable jaw is screwed onto the camera body, it moves away from the optical axis and engages with the camera body.

[0011] Optionally, in the initial state, the part of the movable claw used to engage with the camera body is flush with the outer edge of the mount body, and when the movable claw is screwed onto the camera body, it moves downward away from the optical axis and protrudes from the outer edge of the mount body.

[0012] Optionally, after the movable claw is released from the trigger state of the bayonet body, the movable claw moves towards the optical axis and becomes flush with the outer edge of the bayonet body.

[0013] Optionally, the movable jaw includes a jaw component and a reset component for contacting the camera body and moving the movable jaw. The jaw component and the reset component are connected. The reset component moves towards the optical axis upon contact with the camera body and moves the jaw component away from the optical axis.

[0015] Optionally, the reset assembly includes an actuating component and a movable component connected to the actuating component. The movable component is exposed on the outer edge of the bayonet body and is used to move toward the optical axis when screwed onto the camera body, thereby driving the actuating component to push the jaw component away from the optical axis.

[0016] Optionally, the actuating component includes a sliding member slidably connected to the jaw body and an elastic member connected to the sliding member. The movable member is connected to the sliding member and is used to push the sliding member to slide, and drive the jaw member to move away from or towards the optical axis through the sliding member.

[0017] Optionally, the slider has a first groove and a second groove, the claw is slidably connected to the first groove, and the movable member is connected to the second groove and used to push the slider to slide, so that the slider drives the claw to move away from or towards the optical axis.

[0019] Optionally, the slider also has a third slide groove, and the bayonet further includes a slide groove fastener, which passes through the third slide groove and is connected to the bayonet body.

[0020] Optionally, two third slide grooves and two slide groove fasteners are provided. The two third slide grooves are respectively provided at both ends of the sliding member, and the first slide groove and the second slide groove are located between the two third slide grooves.

[0021] Optionally, the claw component includes a latching portion for extending out of the outer edge of the jaw body and a connecting portion connected to the latching portion, the connecting portion being connected to the reset assembly.

[0022] Optionally, the snap-fit ​​portion has an arc-shaped strip structure.

[0023] Optionally, the angle formed by the line connecting the two ends of the movable claw to the optical axis is the same as the angle formed by the line connecting the two ends of the fixed claw to the optical axis.

[0025] 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, inserts the movable jaw and the fixed jaw into the corresponding notch of the camera body. When the movable jaw is screwed onto the camera body, its movement engages with the camera mount of the camera body, allowing the lens to be securely mounted on the camera body. Thus, during assembly, the movable jaw is in its initial state, reducing collisions with the camera mount. After assembly, triggered by the screwing of the camera body, the movable jaw moves away from the optical axis and engages with the camera body. This ensures reliable assembly while reducing collisions and the feeling of jamming during assembly, improving the user experience.

Utilizing the movable claw of the mount, during assembly, the movable claw is in its initial state, which can reduce collisions with the camera mount. After assembly, under the triggering of the camera body's rotation, the movable claw moves away from the optical axis and engages with the camera body. While ensuring reliable assembly, it reduces collisions and the feeling of jamming during assembly, thereby improving the user experience.

[0028] Thirdly, embodiments of this application also provide a lens, including a lens body and a bayonet as described above, the bayonet being connected to the lens body.

[0029] The lens provided in this application embodiment has at least the following beneficial effects: Compared with the prior art, the lens provided in this application embodiment utilizes the movable claw of the bayonet. During assembly, the movable claw is in its initial state, which can reduce collisions with the camera mount.

[0051] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0054] 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.

[0055] Please refer to this as well. Figure 1 and Figure 12 This application provides a bayonet mount 1, which can be installed as a component in a lens (e.g., ...). Figure 12As shown), it can also be installed as a component in an adapter ring (the adapter ring allows lenses of different mount standards to be mounted on the camera body 2), and the mount 1 can be set to various mount standards according to the camera. For ease of explanation, this application embodiment will describe the usage scenario with the mount 1 installed on the lens, but this is not a limitation of this application embodiment. This application embodiment can also be applied to adapter rings or other devices.

[0056] Please refer to this as well. Figures 1 to 3 The bayonet 1 in this embodiment includes a bayonet body 11, a mounting component 116, a fixed jaw 114, and a movable jaw 12. The mounting component 116 is connected to the bayonet body 11 and is used to mount the bayonet body 11 onto the lens body 3 (see reference). Figure 12 The fixed jaw 114 and the movable jaw 12 are connected to the bayonet body 11, and the movable jaw 12 can move towards or away from the optical axis. When the lens equipped with the bayonet 1 of this embodiment is docked with the camera body 2, the camera body 2 has a camera bayonet 21 (see reference). Figure 9 and Figure 14 The camera mount 21 has camera jaws 211 for docking, and the movable jaws 12 can be aligned with the corresponding mounting notches 212 of the camera mount 21, such as... Figure 8 and Figure 9 As shown, since the movable claw 12 has not yet been triggered by the camera body 2, the movable claw 12 will not directly collide with the camera body 2 and the camera mount 21, making the docking of the lens and the camera body 2 smoother and significantly improving the docking feel.

[0057] like Figures 8 to 10 As shown, when the lens is docked with the camera body 2 and rotated, the camera body 2 will contact the movable claw 12 of the bayonet mount 1, that is, the movable claw 12 will screw into the camera body 2. At this time, the movable claw 12 will be triggered, causing it to move away from the optical axis, that is, to move closer to the camera claw 211, so that the movable claw 12 engages with the camera claw 211, thus installing the lens. Conversely, when removing the lens, after the lens is rotated by a preset angle in the direction of removal, the camera body 2 will release the triggered state of the movable claw 12. At this time, the movable claw 12 can automatically return to its initial state, causing it to move closer to the optical axis, that is, to move away from the camera claw 211. The lens can then be removed. The retracted movable claw 12 reduces collision with the camera body 2, making the removal smoother. Thus, during the lens docking process, the movable claw 12 of the mount 1 reduces the direct collision between the movable claw 12 and the camera body 2, making the lens assembly and disassembly smoother and improving the feel of the lens assembly and disassembly.

[0058] For example, the mounting component 116 can be a bayonet screw, and the main body 111 of the bayonet body 11 is provided with a plurality of screw holes at intervals, through which the bayonet screw can be connected to the lens.

[0059] In other embodiments, the mounting component 116 may also be a snap-fit, adhesive, or threaded structure, etc.

[0060] As one of the optional implementation methods of this application, please refer to Figure 4 and Figure 6 In the initial state, the part of the movable claw 12 that engages with the camera body 2 (i.e., the camera claw 211 of the camera mount 21) is flush with the outer edge of the mount body 11. When the movable claw 12 is screwed onto the camera body 2, it moves away from the optical axis and protrudes beyond the outer edge of the mount body 11. When the lens is docked with the camera body 2, the movable claw 12, which is flush with the outer edge of the mount body 11, significantly reduces the collision between the movable claw 12 and the camera body 2, improving the feel of lens mounting. During lens docking and rotation, the movable claw 12 moves and approaches the camera claw 211 with the help of the camera mount 21, engaging the two and ensuring the reliability of lens mounting.

[0061] Furthermore, as one optional implementation method of this application, please refer to... Figure 6 and Figure 7 After the movable jaw 12 is released from its triggered state with the mount body 11, the movable jaw 12 moves towards the optical axis and does not protrude beyond the outer edge of the mount body 11. When the lens is reversed for disassembly, the camera body 2 releases the triggered state of the movable jaw 12. At this time, the movable jaw 12 can return to its initial state and retract towards the optical axis, making the movable jaw 12 basically flush with the outer edge or outer surface of the mount body 11. This reduces the collision between the lens and the camera body 2 during lens disassembly and improves the feel of lens disassembly.

[0062] It should be noted that the fact that the movable claw 12 is flush with the outer edge of the jaw body 11 in this embodiment can mean that the outer edge of the movable claw 12 is basically flush with the outer edge of the jaw body 11, or that the outer edge of the movable claw 12 is slightly concave compared with the outer edge of the jaw body 11, and the movable claw 12 is in a hidden or semi-hidden state.

[0063] As one of the optional implementation methods of this application, please refer to Figures 2 to 5The movable jaw 12 includes a jaw component 123 and a reset component 120. The jaw component 123 and the reset component 120 are connected. The reset component 120 is used to contact the camera body 2 and drive the movable jaw 12 to move. When the lens is docked with the camera body 2, the reset component 120 can move towards the optical axis, that is, it can move away from the camera jaw 211. As the reset component 120 moves, it will drive the jaw component 123 to move away from the optical axis, that is, the reset component 120 will move towards the camera jaw 211 and engage with the camera jaw 211. Conversely, when the lens is reversed and disassembled, the camera body 2 will contact the reset component 120. At this time, the reset component 120 can move away from the optical axis and drive the jaw component 123 to move towards the optical axis, returning to the initial state.

[0064] This design allows the reset component 120 to switch between an initial state and a triggered state in cooperation with the camera body 2, and to move the latch 123. During lens installation, the latch 123 extends beyond the outer edge of the mount body 11 and securely engages with the camera latch 211, ensuring reliable lens installation while improving the lens's handling. Conversely, during disassembly, the reset component 120 retracts and resets the latch 123, facilitating lens removal.

[0065] Specifically, as one of the optional implementation methods of this application, please refer to Figure 4 and Figure 6 The end of the reset assembly 120 is exposed on the outer edge or outer surface of the mount body 11. When the lens is mounted to the camera body 2, the camera body 2 will contact and press against the exposed part of the reset assembly 120, causing the exposed part of the reset assembly 120 to move in the direction of the optical axis. Conversely, when the lens is removed, when the camera body 2 releases its contact with the exposed reset assembly 120, the reset assembly 120 can drive the jaw 123 to reset. In this way, by using the partially exposed reset assembly 120 in cooperation with the camera body 2, the reciprocating movement of the movable jaw 12 is realized, reducing the feel of lens installation and removal. At the same time, after the lens is installed, the camera body 2 will continuously press against the exposed reset assembly 120, keeping the reset assembly 120 and the jaw 123 in a stable state, ensuring the reliability of lens installation.

[0066] As one of the optional implementation methods in this embodiment, please refer to Figures 2 to 4The reset assembly 120 includes an actuating component 121 and a movable component 122. The movable component 122 is connected to the actuating component 121 and protrudes from the outer edge of the mount body 11. When triggered by the camera body 2, the movable component 122 moves towards the optical axis, causing the actuating component 121 to push the jaw component 123 away from the optical axis. Please refer to the following instructions during lens mounting to the camera body 2: Figures 6 to 10 When the camera body 2 contacts and presses against the movable part 122, the movable part 122 moves towards the optical axis, which in turn drives the actuator 121 to push the jaw 123, causing the jaw 123 to move away from the optical axis, thus locking the lens in place. In this way, the extension and retraction of the jaw 123 is achieved through the cooperation of the movable part 122 and the actuator 121, which helps improve the sensitivity and smoothness of the reset assembly 120 and enhances the user experience.

[0067] Specifically, as one of the optional implementation methods of this application, please refer to Figure 2 and Figure 6 The actuator 121 includes a slider 1211 and an elastic member 1212. The elastic member 1212 is connected to the slider 1211, and the slider 1211 is slidably connected to the bayonet body 11. The movable member 122 is connected to the slider 1211. Specifically, the slider 1211 can slide back and forth between a starting position and an ending position. When the camera body 2 pushes the movable member 122, the movable member 122 pushes the slider 1211 from the starting position to the ending position, using the slider 1211 to drive the jaw member 123 to move away from the optical axis. Conversely, after the camera body 2 releases contact with the movable member 122, the slider 1211 slides from the ending position to the starting position, driving the movable member 122 and the jaw member 123 to reset, thereby realizing the extension and retraction of the movable jaw 12.

[0068] Furthermore, when the slider 1211 is pushed and slides from the starting position to the ending position, it will drive the elastic element 1212, causing the elastic element 1212 to be in a stored state. After the camera body 2 releases contact with the movable element 122, the stored elastic element 1212 will reset and release, driving the slider 1211 back to the starting position. At the same time, the slider 1211 will drive the claw 123 and the movable element 122 to reset. In this way, through the cooperation of the elastic element 1212 and the slider 1211, the movable claw 12 is reset, improving the feel of lens assembly and disassembly.

[0069] For example, the elastic element 1212 can be a spring, one end of which can be connected to the sliding element 1211, and the other end of which can be connected to the jaw body 11 by the elastic fastener 1214, which can be a screw. Furthermore, in the initial state of the movable jaw 12, the spring can be in a natural state (i.e., not stretched or compressed) or in a stretched state. The spring in the stretched state can act on the sliding element 1211 to keep the sliding element 1211 in the starting position and ensure the stability of the movable jaw 12.

[0070] Of course, in other embodiments, the elastic element 1212 can also be a spring sheet or a miniature motor, etc.

[0071] For details, please refer to Figure 6 and Figure 7 The slider 1211 slides along the circumferential direction of the jaw body 11 under the push of the movable part 122. That is, the starting position and the ending position of the slider 1211 are both located in the circumferential direction of the jaw body 11. The slider 1211 slides back and forth in the circumferential direction of the jaw body 11, thereby driving the extension and retraction of the claw part 123. This design can effectively reduce the space occupied by the slider 1211 on the jaw body 11 and improve the space utilization rate.

[0072] Furthermore, as one optional implementation method of this embodiment, please refer to... Figure 2 and Figure 6 The slider 1211 has a first groove 1211a and a second groove 1211b. The claw 123 is slidably connected to the first groove 1211a. The movable member 122 is connected to the second groove 1211b and is used to push the slider 1211 to slide, so that the slider 1211 drives the claw 123 to move away from or closer to the optical axis.

[0073] Please refer to Figure 6 and Figure 7When the movable part 122 is triggered by the camera body 2, that is, when the camera body 2 applies a force to the movable part 122, the movable part 122 can transmit the force to the sliding part 1211 through the second slide groove 1211b, and push the sliding part 1211 from the starting position to the ending position; further, during the process of the sliding part 1211 sliding to the ending position, since the claw part 123 is connected to the sliding part 1211 through the first slide groove 1211a, under the action of the sliding part 1211, the claw part 123 will move in a direction away from the optical axis, that is, the claw part 123 is in the extended state. Conversely, when the camera body 2 is deactivated, the slider 1211 will slide from the end position to the start position. Driven by the slider 1211, the moving part 122 and the claw part 123 will reset. The claw part 123 will move towards the center of the claw body and return to the retracted state, which reduces direct collision with the camera body 2 when the lens is disassembled and improves the feel of lens disassembly and assembly.

[0074] Specifically, as one of the optional implementation methods of this embodiment, please refer to Figure 6 and Figure 7 The extension lines of the first slide groove 1211a and the second slide groove 1211b in the length direction both intersect the extension line of the sliding member 1211 in the sliding direction.

[0075] For example, the slider 1211 can be a long strip with a certain curvature. The sliding direction of the slider 1211 is the circumferential direction of the virtual circle in which the slider 1211 is located. The length direction of the first groove 1211a and the second groove 1211b intersects the circumferential direction of the virtual circle. That is, the sliding direction of the slider 1211 is different from the sliding direction of the movable part 122 and the claw part 123.

[0076] Furthermore, as one optional implementation method of this embodiment, please refer to... Figure 6 and Figure 7The extension lines of the first slide groove 1211a and the second slide groove 1211b in the length direction intersect, meaning that the setting direction of the first slide groove 1211a and the second slide groove 1211b are different. For example, both the first slide groove 1211a and the second slide groove 1211b can be elongated slide grooves. The first slide groove 1211a and the second slide groove 1211b can be mirror-symmetrically arranged. When the movable member 122 is not yet triggered by the camera body 2, the movable member 122 is connected to the end of the second slide groove 1211b near the first slide groove 1211a, and the claw member 123 is connected to the end of the first slide groove 1211a away from the second slide groove 1211b. In the triggered state, the movable member 122 slides to the end of the second slide groove 1211b away from the first slide groove 1211a, simultaneously pushing the sliding member 1211, causing the claw member 123 to slide to the end of the first slide groove 1211a near the second slide groove 1211b.

[0077] This design, utilizing the cooperative design of the first slide groove 1211a, the second slide groove 1211b, and the sliding member 1211, enables the sliding member 1211 to convert the force through this cooperative design. That is, the cooperation between the movable member 122 and the second slide groove 1211b converts the force exerted by the movable member 122 on the sliding member 1211 in the direction of the optical axis into a virtual circular circumferential force. Then, through the cooperation between the second slide groove 1211b and the claw member 123, the virtual circular circumferential force is converted into a force exerted by the claw member 123 in the direction away from the optical axis. It has the characteristics of simple structure, reliability, and high efficiency.

[0078] Specifically, as one of the optional implementation methods of this embodiment, please refer to Figure 6 and Figure 7 The slider 1211 also has a third slide groove 1211c, and the bayonet 1 also includes a slide groove fastener 1213. One end of the slide groove fastener 1213 passes through the third slide groove 1211c and is connected to the bayonet body 11. In this way, by using the cooperation of the slide groove fastener 1213 and the third slide groove 1211c, the sliding position of the slider 1211 can be restricted.
