The camera accessory 200 includes a latch structure 22.
The locking structure 22 is movably arranged on the outer ring surface 212 of the second mounting seat 21, which is engaged with the first clamping jaw 111, and when the second mounting seat 21 rotates between the first state and the second state relative to the first mounting seat 11, the locking structure 22 is retracted into the outer ring surface 212; when the second mounting seat 21 is in the second state relative to the first mounting seat 11, the locking structure 22 extends out of the outer ring surface 212 and is locked with the first claw 111, so as to limit the second mounting seat 21 to rotate from the second state to the first state.
In this embodiment, the latch structure 22 uses the first claw 111 to lock rotation. Specifically, when the first mounting seat 11 and the second mounting seat 21 are mounted by rotating relatively, the first claw 111 and the second claw 211 are in a mutually hooked state, the second mounting seat 21 is further provided with an outer ring surface 212 which is engaged with the first claw 111 in the circumferential direction, the first claw 111 rotates along the outer ring surface 212 in the circumferential direction relatively to the second claw 211, so that in order to limit the rotation between the two claws, the locking structure 22 is movably arranged on the outer ring surface 212, and when the two claws are allowed to rotate relatively, namely, the second mounting seat 21 rotates between a first state and a second state relatively to the first mounting seat 11, the locking structure 22 is retracted into the outer ring surface 212 to avoid interference; when the two jaws are limited to rotate relatively, that is, the second mounting seat 21 is in the second state relative to the first mounting seat 11, the locking structure 22 extends out of the outer ring 212, and is locked to the first jaw 111 to abut against the end of the first jaw 111, so as to prevent rotation.
There are various structural designs for realizing the extending and retracting movement of the locking structure 22, and different structural designs can be realized by user operation or can be automatically completed by the structure. In this embodiment, when the camera needs to replace the camera accessory 200, the camera accessory 200 needs to be unlocked in the second state, so that the camera accessory 200 can rotate to the first state relative to the camera body 100, thereby realizing disassembly, and an unlocking structure is further provided on the camera accessory 200.
Specifically, the camera accessory 200 further includes an accessory housing 23 and an unlocking button 24, the second mount 21 is disposed at an end of the accessory housing 23, the unlocking button 24 is disposed at a side of the accessory housing 23, and is connected to the latch structure 22, and acts on the latch structure 22 to enable the latch structure 22 to retract into the outer ring surface 212 so as to unlock the latch structure 22 and the first claw 111.
The accessory housing 23 is a housing of the camera accessory 200, and the second mount 21 is disposed at an end of the accessory housing 23, and if the camera accessory 200 is a lens, an optical lens module, a circuit board, and the like are further disposed in the accessory housing 23. If the camera accessory 200 is an adapter ring, one end is provided with a second mounting seat 21 matched with the camera body 100, the other end is provided with a mounting seat matched with an adapter lens, and a circuit structure can be also arranged in the camera accessory.
The unlocking button 24 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. The unlocking key 24 provides a user operation, and when the user presses the unlocking key 24, the movement of the unlocking key 24 can drive 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 seat 21 is connected with the first mounting seat 11, and is not exposed outside when the camera is in use, so that the unlocking key 24 is arranged on the side surface of the accessory housing, so that the operation of a user is facilitated.
When the camera accessory 200 needs to be detached, the user can rotate the camera accessory 200 while pressing the unlocking key 24 with one hand, thereby detaching the camera accessory 200. If the unlocking key 24 is provided on the camera body 100, the user needs to press the unlocking key on the camera body 100 with one hand and rotate the camera accessory 200 with the other hand. The mode that the unlocking key 24 is arranged on the camera accessory 200 is more convenient to operate in the application.
In order to reduce user operations and improve user experience, the camera accessory 200 is embedded into the camera body 100 from the first state and rotated from the first state to the second state, and in the process of fastening in the second state, the embodiment realizes automatic fastening through the structural design of the latch structure 22.
Specifically, the latch structure 22 is elastically movably disposed relative to the outer annular surface 212 in an axial direction or a radial direction of the camera accessory 200, and when the second mounting seat 21 rotates between the first state and the second state relative to the first mounting seat 11, the latch structure 22 is pressed into the outer annular surface 212 by the first claw 111; when the second mounting seat is in the second state relative to the first mounting seat, the locking structure 22 is ejected from the outer ring surface 212.
The elastic movement of the latch structure 22 can automatically lock, when no external force acts on the latch structure 22, the latch structure 22 pops up the outer ring surface 212, and when external force acts on the latch structure 22 can be pressed into the outer ring surface. The automatic buckling of the locking structure can be realized by utilizing the movement between the first mounting seat 11 and the second mounting seat 21 and the structures of the first mounting seat and the second mounting seat.
In mounting the camera accessory 200, the second mount 21 is first inserted into the first mount 11, where there is axial movement of both; the second mounting seat 21 is then rotated relative to the first mounting seat 11, and there is circumferential movement between the two; therefore, the locking structure 22 can be retracted into the outer ring surface in the axial direction or the radial direction by utilizing two movements, specifically, the locking structure 22 is pressed into the outer ring surface 212 by utilizing the first clamping jaw 111, and the locking structure 22 moves between the first clamping jaws when rotating to the second state because the first clamping jaw 111 is a section of circular arc, so that the locking structure can be restored to the protruding outer ring surface 212 under the action of the elastic force without being acted by the first clamping jaw 111.
Based on this principle, since there are a plurality of first claws, each of the first claws in the present application can be used to cooperate with the lock catch structure 22 to achieve locking. The corresponding unlocking key 24 is associated with the location of the latch structure 22 such that the unlocking key 24 is positioned to facilitate thumb depression. For example, when the camera is used horizontally, the first claw located above the horizontal middle line is matched with the locking structure 22, the unlocking key 24 and the locking structure 22 are arranged in one direction in the radial direction, so that the unlocking key 24 can be conveniently pressed by a thumb of a user, and the operation of the user is facilitated.
In the present embodiment, the latch structure 22 is elastically movably disposed relative to the outer ring surface 212 in the axial direction of the camera accessory 200.
