[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. It is understood that the specific embodiments described herein are only for explaining this application and not for limiting it. Furthermore, it should be noted that, for ease of description, only the parts related to this application are shown in the accompanying drawings, not all structures. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0027] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0028] Please see Figure 1 , Figure 1 This is a structural schematic diagram of the camera accessory and camera body of this application, that is, a structural schematic diagram of the camera system. The camera accessory 200 of this application is configured to be installed on a camera body 100 having a first mounting base 11, the first mounting base 11 including a plurality of first latches 111. The camera accessory 200 includes a second mounting base 21, the second mounting base 21 including a plurality of second latches 211; the second mounting base 21 rotates relative to the first mounting base 11 between a first state and a second state. In the first state, all the second latches 211 are inserted between the first latches 111; in the second state, the second latches 211 engage with the first latches 111.

[0029] In this application, the camera body 100 and the camera accessory 200 are separately configured, and the camera accessory 200 can be detachably installed on the camera body 100. The camera accessory 200 can be a lens or an adapter ring. If the camera accessory 200 is a lens, it can be directly connected to the camera body 100 to form a shooting camera; if it is an adapter ring, lenses with different mounts can be connected to the camera body 100 to form a shooting camera.

[0030] The camera body 100 and the camera accessory 200 are installed by the cooperation of the mounting base. The first mounting base 11 of the camera body 100 has multiple first claws 111, and the second mounting base 21 of the camera accessory 200 has multiple second claws 211. The first mounting base 11 and the second mounting base 21 are rotated to achieve the insertion, engagement and disengagement of the first claws 111 and the second claws 211.

[0031] Specifically, the second mounting base 21 rotates relative to the first mounting base 11 between a first state and a second state. The first state is the insertion and disassembly state, in which the second claws 211 are inserted between the first claws 111. For example, the first mounting base 11 has three first claws 111, which together form three first slots; the second mounting base 21 has three second claws 211, which are inserted into the three first slots to achieve insertion. The second state is the engagement state, in which the camera accessory 200 is docked and installed with the camera body 100. At this time, the second claws 211 engage with the first claws 111. After the second claws 211 are inserted between the first claws 111, they rotate to overlap with the first claws 111, thereby achieving engagement between the two and allowing the camera accessory 200 to be stably fixed on the camera body 100.

[0032] The camera accessory 200 and the camera body 100 are connected by clips, and the weight of the camera accessory 200 is supported by the clamping force between the clips. Therefore, the first mounting base 11 and the second mounting base 21 require high strength, and are generally made of metal, but high-strength plastic materials can also be used.

[0033] The camera accessory 200 and the camera body 100 can be locked in the axial direction by means of a latch. In order to make the camera stable, it is also necessary to lock the movement of the camera accessory and the camera body in the circumferential direction to prevent them from rotating relative to each other. Therefore, the camera accessory in this application is also provided with a locking structure.

[0034] Please refer to the details. Figures 2-5 , Figure 2 This is a structural schematic diagram of the first embodiment of the camera accessory of this application. Figure 3 yes Figure 2 Another structural schematic diagram of the first embodiment of the camera accessory shown. Figure 4 yes Figure 2 The diagram shown illustrates the locking structure retracting into the outer ring surface in the first embodiment of the camera accessory. Figure 5 yes Figure 2 The diagram shows a schematic of the linkage structure in the first embodiment of the camera accessory. The camera accessory 200 includes a locking structure 22.

[0035] The locking structure 22 is movably disposed on the outer ring surface 212 of the second mounting base 21, which engages with the first claw 111. When the second mounting base 21 rotates relative to the first mounting base 11 between the first state and the second state, the locking structure 22 retracts into the outer ring surface 212. When the second mounting base 21 is in the second state relative to the first mounting base 11, the locking structure 22 extends out of the outer ring surface 212 and engages with the first claw 111 to restrict the second mounting base 21 from rotating from the second state to the first state.

[0036] In this embodiment, the locking structure 22 utilizes the first pawl 111 to achieve rotational locking. Specifically, when the first mounting base 11 and the second mounting base 21 are installed with relative rotation, the first pawl 111 and the second pawl 211 are in a hooked state. The second mounting base 21 also has an outer ring surface 212 that engages with the first pawl 111 in the circumferential direction. The first pawl 111 will rotate relative to the second pawl 211 in the circumferential direction along the outer ring surface 212. Therefore, in order to restrict the rotation between the two pawls, the locking structure 22 is movably disposed on the outer ring surface 212. When the two pawls are allowed to rotate relative to each other, that is, when the second mounting base 21 rotates relative to the first mounting base 11 between the first state and the second state, the locking structure 22 retracts into the outer ring surface 212 to avoid interference. When the two pawls are restricted from rotating relative to each other, that is, when the second mounting base 21 is in the second state relative to the first mounting base 11, the locking structure 22 extends out of the outer ring surface 212, engages with the first pawl 111, and abuts against the end of the first pawl 111 to prevent it from rotating.

[0037] There are various structural designs that enable the extension and retraction of the locking structure 22. Different structural designs can be implemented by user operation or automatically by the structure itself. In this embodiment, when the camera needs to replace the camera accessory 200, it needs to be unlocked in the second state so that the camera accessory 200 can rotate relative to the camera body 100 to the first state, thereby achieving disassembly. An unlocking structure is also provided on the camera accessory 200.

[0038] Specifically, the camera accessory 200 also includes an accessory housing 23 and an unlock button 24. The second mounting base 21 is located at the end of the accessory housing 23, and the unlock button 24 is located on the side of the accessory housing 23. It is connected to the locking structure 22 and acts on the locking structure 22 to retract the locking structure 22 into the outer ring surface 212, so as to unlock the locking structure 22 and the first claw 111.

[0039] The accessory housing 23 is the housing of the camera accessory 200. The second mounting base 21 is located at the end of the accessory housing 23. If the camera accessory 200 is a lens, the accessory housing 23 also contains an optical lens module, circuit board, and other structures. If the camera accessory 200 is an adapter ring, one end is provided with a second mounting base 21 that mates with the camera body 100, and the other end is provided with a mounting base that mates with the adapter lens. Circuit structures can also be installed inside the adapter ring.

[0040] The unlock button 24 is connected to the locking structure 22 and acts on the locking structure 22, causing the locking structure 22 to retract into the outer ring surface 212, thereby releasing the engagement between the locking structure 22 and the first claw 111. The unlock button 24 is provided for user operation. When the user presses the unlock button 24, the movement of the unlock button 24 can cause the locking structure 22 to retract into the outer ring surface 212, so that the camera accessory 200 can be unlocked in the second state. The second mounting base 21 is connected to the first mounting base 11 and is not exposed when the camera is in use. Therefore, the unlock button 24 is located on the side of the accessory housing for easy user operation.

[0041] Furthermore, the unlock button 24 is located on the camera accessory 200. When it is necessary to disassemble the camera accessory 200, the user can press the unlock button 24 and rotate the camera accessory 200 with one hand to achieve disassembly. If the unlock button 24 were located on the camera body 100, the user would need to press the unlock button on the camera body 100 with one hand and rotate the camera accessory 200 with the other hand. The method of placing the unlock button 24 on the camera accessory 200 in this application is more convenient to operate.

[0042] To reduce user operations and improve user experience, this embodiment achieves automatic fastening through the structural design of the locking structure 22 during the process of the camera accessory 200 being embedded into the camera body 100 from the first state and rotating from the first state to the second state and fastening in the second state.

[0043] Specifically, the locking structure 22 is elastically movable relative to the outer ring surface 212 in the axial or radial direction of the camera accessory 200. When the second mounting base 21 rotates relative to the first mounting base 11 between the first state and the second state, the locking structure 22 is pressed into the outer ring surface 212 by the first claw 111. When the second mounting base is in the second state relative to the first mounting base, the locking structure 22 pops out of the outer ring surface 212.

[0044] The elastically movable locking structure 22 enables automatic engagement. When no external force is applied, the locking structure 22 pops out from the outer ring surface 212; when an external force is applied, the locking structure 22 can be pressed into the outer ring surface. Thus, the automatic engagement of the locking structure can be achieved through the movement between the first mounting base 11 and the second mounting base 21, and their respective structures.

[0045] When installing camera accessory 200, the second mounting base 21 is first inserted into the first mounting base 11, at which point there is axial movement between the two; then the second mounting base 21 rotates relative to the first mounting base 11, at which point there is circumferential movement between the two; thus, the two movements can be used to make the locking structure 22 retract into the outer ring surface in the axial or radial direction. Specifically, the first pawl 111 is used to press the locking structure 22 into the outer ring surface 212. Since the first pawl 111 is an arc, when rotating to the second state, the locking structure 22 moves between the first pawls and is no longer subject to the force of the first pawl 111. Under the action of elastic force, it can return to protruding from the outer ring surface 212, thus achieving locking.

[0046] Based on this principle, since there are multiple first claws, each first claw in this application can be used to cooperate with the locking structure 22 to achieve locking. The corresponding unlock button 24 is related to the position of the locking structure 22, allowing the unlock button 24 to be positioned conveniently for the user's thumb to press. For example, using the first claw located above the horizontal center line when the camera is used horizontally, and cooperating with the locking structure 22, the unlock button 24 and the locking structure 22 are arranged in the same radial direction, thus making the unlock button 24 conveniently positioned for the user's thumb to press, and improving user operation.

[0047] In this embodiment, the locking structure 22 is elastically movable relative to the outer annular surface 212 in the axial direction of the camera accessory 200. A linkage structure 25 is provided between the unlocking button 24 and the locking structure 22. The unlocking button 24 moves radially to drive the locking structure 22 to move axially through the linkage structure.

[0048] The unlock button 24 is located on the side of the accessory housing 23, and its movement direction is set to radial. Therefore, the function of the linkage structure 25 is to convert the radial movement of the unlock button 24 into the axial movement of the locking structure 22.

[0049] The linkage structure 25 includes a V-shaped transmission component 251, the bend of which is rotatably mounted on the second mounting base 21. One end is connected to the locking structure 22, and the other end is connected to the release button 24. The V-shaped transmission component 252 is used to realize the direction of movement. Its bend is rotatably mounted. When the V-shaped transmission component rotates around the bend, the two ends of the V-shape can move in different directions.

[0050] The linkage structure 25 also needs to cooperate with the guide part 26 fixedly mounted on the second mounting base 21 to realize the movement of the locking structure 22. The turning point of the V-shaped transmission member 251 is rotatably mounted on the guide part 26. The guide part 26 is used to limit the movement direction of the locking structure 22, and is provided with an axial guide groove 261. The locking structure 22 is disposed in the axial guide groove 261 to realize axial movement along the guide groove 261.

[0051] In order to achieve the elastic reset setting of the locking structure 22, a reset snap ring is provided at the rotational connection between the V-shaped transmission member 251 and the guide part 26. In the natural state of the reset snap ring, the locking structure 22 extends out of the outer ring surface 212.

[0052] In other embodiments, the locking structure is resiliently movable relative to the outer annular surface in the radial direction of the camera accessory. Specifically, as shown... Figure 6-7 as well as Figure 8-9 , Figure 6 This is a structural schematic diagram of the second embodiment of the camera accessory of this application. Figure 7 yes Figure 6 Another structural schematic diagram of the second embodiment of the camera accessory shown; Figure 8 This is a structural schematic diagram of the third embodiment of the camera accessory of this application. Figure 9 yes Figure 8 The diagram shows a structural schematic of the locking structure in the third embodiment of the camera accessory.

[0053] exist Figure 6-9 In China, camera accessories are serialized using the number 300, and the number corresponds to... Figure 2-5 The numbers in the illustrated embodiment correspond. The locking structure 32 in the camera accessory 300 is movably disposed in the radial direction of the camera accessory 300 relative to the outer annular surface 312.

[0054] The camera accessory 300 in this embodiment is basically the same as the camera accessory 200 in the above embodiment, except for the setting of the locking structure 32. In this embodiment, the locking structure 32 is radially movable relative to the outer ring surface 312. The unlocking button 34 abuts against the locking structure 32, and the radial movement of the unlocking button 34 causes the locking structure 32 to move radially.

[0055] The locking structure 32 includes a locking part 321, a fixing part 322, and a reset elastic part 323. The fixing part 323 is fixedly connected to the second mounting base 31. The locking part 321 is connected to the fixing part 322 through the reset elastic part 323. One end of the locking part 321 extends and retracts on the outer ring surface 312, and the other end abuts against the unlock button 34. In the natural state of the reset elastic part 323, the locking part 321 extends out of the outer ring surface 312.

[0056] The locking structure 32 can take many forms, such as Figure 6-7 As shown, the reset elastic member 323 is a snap ring, the locking part 321 is rotatably disposed on the fixed part 322, and the reset elastic member 323, as a snap ring, is sleeved on the fixed part and abuts against the locking part 321 and the fixed part 322.

[0057] like Figure 8-9 As shown, the locking structure 32 is a spring piece, with the first end of the spring piece being the locking part 321, the second end being the fixing part 323, and the space between the two ends being the elastic part 323.

[0058] The spring is mainly set on the end face of the second mounting base 31 opposite to the first mounting base. The second mounting base 31 is also provided with a fixing post 313 and a limiting groove 314. The second end of the spring is fixed to the fixing post 313 and the spring is embedded in the limiting groove 314. The limiting groove 314 is used to limit the outward expansion of the spring.

[0059] for Figure 6-9 In the two embodiments described, the locking part 321 extends outward from the outer annular surface 312 in the circumferential direction, direction A, which is opposite to the mounting rotation direction B of the camera accessory 300 relative to the camera body 100. The locking part 321 is tilted upward in direction A. When the camera accessory 300 is mounted on the camera body and rotates relative to the camera body 100, the first claw 11 can act along the locking part 321 to press the locking part 321 into the outer annular surface 312.

[0060] In summary, the camera accessory of this application is configured to be mounted on a camera body having a first mounting base, the first mounting base including a plurality of first claws; the camera accessory includes: a second mounting base, the second mounting base including a plurality of second claws; the second mounting base rotates relative to the first mounting base between a first state and a second state; in the first state, all second claws are inserted between the first claws; in the second state, the second claws engage with the first claws; a locking structure is movably disposed on the outer annular surface of the second mounting base that engages with the first claws; when the second mounting base rotates relative to the first mounting base between the first and second states, the locking structure retracts into the outer annular surface; in the second state, when the second mounting base is relative to the first mounting base, the locking structure extends out of the outer annular surface and engages with the first claws to restrict the second mounting base from rotating from the second state to the first state. The camera accessory of this application can achieve a secure locking using the claws on the camera body. The camera accessory and the camera body are engaged by a latch, and after engagement, they are locked together by a locking structure to restrict relative rotation. The locking structure on the camera accessory specifically engages the latch on the camera body. Due to the stability of the latch itself, this application can achieve a stable lock.
