The specific meaning of the above terms in the present application will be understood in specific cases by those of ordinary skill in the art.
Referring to fig. 1, the present invention provides a photographing assisting apparatus 100, and the photographing assisting apparatus 100 may be provided with a photographing device and a photographing assisting device to assist the photographing device in photographing. The photographing apparatus may be any electronic apparatus having a camera, such as a camera, a cellular phone, a tablet computer, etc., and the photographing auxiliary equipment may be a monitor, a photographing lamp, a microphone, a flash, etc. The photographing auxiliary device 100 provided by the invention is portable, the portable device body 110 is provided, the device body 110 is a portable part which can be held by hands to complete photographing operation. It will be appreciated that in other embodiments, the photographing auxiliary device 100 may be, but not limited to, a photographing assisting handle, a supporting frame, a camera rabbit cage, or the like. The device body 110 at this time can be correspondingly understood as a handle body, a support body, and a rabbit cage body.
The photographing auxiliary device 100 includes a device body 110 and a rotation structure 200, the device body 110 may be provided with a first mounting portion 101, the rotation structure 200 may be provided with a second mounting portion 102, the first mounting portion 101 and the second mounting portion 102 may be used for mounting photographing equipment and photographing auxiliary equipment, respectively, and the first mounting portion 101 and the second mounting portion 102 may be, but are not limited to, a quick-mounting seat, a screw connection, a screw hole, etc. The apparatus body 110 is rotatable about the rotation axis of the rotation structure 200, so that the photographing device or the photographing auxiliary equipment of the apparatus body 110 located at the first mounting portion 101 can be rotated with respect to the rotation structure 200.
Fig. 1 also illustrates that the rotation structure 200 is slidable along the length extension direction of the device body 110, so that the height of the second mounting portion 102 provided at the end of the rotation structure 200 can be switched. When the rotating structure 200 needs to be slid, the screw between the rotating structure 200 and the device body 110 can be loosened, and then slid to a preset position along the length direction of the device body 110, and when the rotating structure 200 slides to the preset position, the screw is tightened again to fix the rotating structure 200 to the preset position. It will be appreciated that in other embodiments, the rotating structure 200 may be configured to be vertically non-slidable relative to the device body 110.
Referring to fig. 2 and 3, the rotating structure 200 includes a main body 300 and a locking assembly 400. The main body 300 includes a sleeve 310 and a rotating rod 320, the rotating rod 320 rotatably penetrates the sleeve 310 along the circumferential direction of the sleeve 310, and bearings 321 may be respectively disposed at both ends of the rotating rod 320 to improve centering when the rotating rod 320 rotates. It will be appreciated that the sleeve 310 is provided with a rotation groove 311, and the rotating lever 320 is penetrated through the rotation groove 311. The end of the sleeve 310 far away from the rotating rod 320 is connected with the device body 110, the end of the rotating rod 320 far away from the sleeve 310 is used for being connected with shooting equipment through a second mounting part 102 arranged at the tail end of the rotating rod 320, and when the rotating rod 320 rotates along the circumferential direction, the rotating rod 320 can carry the shooting equipment to switch angles in the circumferential direction. In other embodiments, the sleeve 310 is connected with the photographing apparatus, and the rotation lever 320 is connected with the device body 110.
The locking assembly 400 includes a first locking member 410 and a second locking member 420, each of the first locking member 410 and the second locking member 420 being switchable between a respective locked position and an unlocked position. When the first locking element 410 and the second locking element 420 are both in the respective locking positions, the rotating rod 320 is circumferentially limited to the sleeve 310, which is understood that the rotating rod 320 cannot complete the circumferential rotation action relative to the sleeve 310.
It will be appreciated that when the first locking member 410 is in the unlocked position and the second locking member 420 is in the locked position, the rotating lever 320 is able to rotate in the forward direction and the second locking member 420 limits the rotation of the rotating lever 320 in the reverse direction. It is understood that the rotating rod 320 cannot perform the reverse rotation in the circumferential direction with respect to the sleeve 310, i.e., the rotating rod 320 can rotate in one direction in the forward direction, but the rotating rod 320 cannot rotate in the reverse direction. It should be noted that, in the embodiments of the present invention, the "forward direction" and the "reverse direction" are relatively, and when the "forward direction" is understood as a clockwise direction, the "reverse direction" may be understood as a counterclockwise direction. When "forward" is understood to be counterclockwise, "reverse" may be understood to be clockwise.
When the first locking member 410 is in the locked position and the second locking member 420 is in the unlocked position, the rotating lever 320 can rotate in the reverse direction, and the first locking member 410 limits the rotating lever 320 from rotating in the forward direction. It is understood that the rotation of the rotation lever 320 in the forward direction cannot be performed with respect to the sleeve 310 in the circumferential direction, that is, the rotation lever 320 can be rotated in the reverse direction in one direction, but the rotation lever 320 cannot be rotated in the forward direction.
When the first locking piece 410 is in the unlocking position and the second locking piece 420 is in the unlocking position, the limit of the rotation of the rotating lever 320 in the forward direction is released, and the limit of the rotation of the rotating lever 320 in the reverse direction is also released. It will be appreciated at this point that the rotary lever 320 can be selectively driven to rotate in either the forward or reverse direction.
It should be emphasized that the foregoing description of the inability of the rotating rod 320 to rotate in a forward direction or the inability of the rotating rod 320 to rotate in a direction is not an absolute limitation, and should be construed broadly herein. That is, the rotation of the rotating rod 320 in the forward direction may be understood as that the frictional resistance of the rotating rod 320 rotating in the forward direction is too high, so that the rotating rod 320 rotates in the forward direction only with a sufficient force to drive the rotating rod 320, which may be very laborious. Likewise, the inability of the rotating lever 320 to rotate in the reverse direction may be understood as an excessive frictional resistance to the rotation of the rotating lever 320 in the reverse direction, and the rotating lever 320 may also be rotated in the reverse direction as long as the force driving the rotating lever 320 is sufficiently large.
In the photographing auxiliary device 100 of the embodiment of the invention, one of the rotating rod 320 and the sleeve 310 may be connected with the photographing apparatus, and the other may be connected with the photographing assisting handle or the supporting frame, and since the first locking member 410 and the second locking member 420 may control the rotating rod 320 to rotate in two different directions (forward or reverse, which may be understood as clockwise or counterclockwise), respectively, the rotation of the photographing apparatus relative to the photographing assisting handle or the supporting frame is realized. During the actual use, the user can selectively operate the first locking member 410 or the second locking member 420 according to the actual use requirement or the operation habit of the user. For example, the first locking piece 410 may be switched to the unlocking position when the user desires the rotation of the rotation lever 320 to adjust the photographing orientation of the photographing apparatus by the forward rotation, and the second locking piece 420 may be switched to the unlocking position when the user desires the rotation of the rotation lever 320 to adjust the photographing orientation of the photographing apparatus by the reverse rotation. On the former basis, if the user does not wish the rotation of the rotation lever 320 in the other opposite direction, the other locking member is simultaneously switched to the locking position to restrict the rotation of the rotation lever 320. Therefore, the invention provides a method for determining whether the rotating rod 320 rotates forward or backward selectively by a user, so as to meet the shooting use requirements of different photographers, and the invention has the advantages of more flexible practicality, compact integral structure, small occupied space and convenient disassembly and assembly.
For a clearer understanding of the present invention regarding the independent manipulation of the first locking member 410 and the second locking member 420 to achieve the forward rotation or the reverse rotation of the rotating lever 320, the present invention will be described in detail herein below with reference.
Referring to fig. 4 and 5, the first locking piece 410 includes a first protrusion 411 between the sleeve 310 and the rotating lever 320, and the second locking piece 420 includes a second protrusion 421 between the sleeve 310 and the rotating lever 420, the second protrusion 421 being circumferentially spaced from the first protrusion 411. The first protrusion 411 and the second protrusion 421 can be driven by an external force to move toward or away from each other along the circumferential direction, when the first protrusion 411 and the second protrusion 421 move toward each other, at least one of the first locking member 410 and the second locking member 420 is switched to the unlocking position, and at this time, the circumferential limit of the rotating lever 320 is released to rotate relative to the sleeve 310. When the first protrusion 411 and the second protrusion 421 are away from each other, parts (rolling bodies described below) in the first locking piece 410 and the second locking piece 420 respectively abut against the rotating lever 320 to restrict circumferential rotation thereof.
In this embodiment, the locking assembly 400 further includes a limiting member 430 and an elastic member 440 disposed between the first protrusion 411 and the second protrusion 421, wherein the limiting member 430 includes a first roller 431 and a second roller 432 circumferentially arranged, and the first roller 431 and the second roller 432 are located between the sleeve 310 and the rotating rod 320. The elastic member 440 is disposed between the first roller 431 and the second roller 432, and the elastic member 440 is in a compressed state, and the elastic force accumulated by the compressed elastic member 440 tends to drive the first roller 431 and the second roller 432 to move towards both ends. It is understood that in other embodiments, the elastic member 440 may not be disposed between the first roller 431 and the second roller 432, for example, the elastic member 440 may include a first elastic body disposed between the first bump 411 and the first roller 431 and a second elastic body disposed between the second bump 421 and the second roller 432, and the first elastic body and the second elastic body are in a stretched state and accumulate elastic force. It should be noted that the elastic member 440 and the elastic body may include, but are not limited to, a spring plate, a spring, and an elastic rubber pad.
When the first locking member 410 and the second locking member 420 are both in the respective locking positions, the elastic force released by the elastic member 440 holds the first roller 431 and the second roller 432 against the rotating rod 320 in opposite directions, and if the rotating rod 320 rotates in the forward direction, a friction force is generated between the rotating rod 320 and the first roller 431 and between the rotating rod 320 and the second roller 432, the friction force between the rotating rod 320 and the first roller 431 acts against the first roller 431, and the direction of the friction force acting against the first roller 431 is toward the direction in which the first roller 431 abuts against the rotating rod 320 (the direction can be understood as the forward direction), and the first roller 431 cannot move continuously under the friction force acting against the rotating rod 320, so that the friction force between the first roller 431 and the rotating rod 320 always exists, i.e., the first roller 431 limits the forward rotation of the rotating rod 320.
If the rotating rod 320 rotates in the opposite direction, a friction force is generated between the rotating rod 320 and the first roller 431 and the second roller 421, the friction force between the rotating rod 320 and the second roller 432 acts against the second roller 432, the direction of the friction force acting against the second roller 432 faces the direction of the rotating rod 320 (the direction can be understood as opposite direction), and the second roller 432 cannot move continuously under the friction force acting against the second roller 432, namely, the second roller 432 limits the rotating rod 320 to rotate in the opposite direction.
The above explanation is about the first locking member 410 and the second locking member 420 being simultaneously in the locking position and being capable of restricting the forward rotation and the reverse rotation of the rotating lever. The unlock position will be explained below.
The first protrusion 411 can move close to the second protrusion 421 along the circumferential direction to drive the first roller 431 to move away from the rotating rod 320 along the radial direction, so that the first locking element 410 is switched to the unlocking position. Similarly, the second protrusion 421 can also move circumferentially close to the first protrusion 411 to drive the second roller 432 radially away from the rotating rod 320, so that the second locking member 420 is switched to the unlocking position.
With the first locking member 410 in the unlocked position and the second locking member 420 in the locked position, the first roller 431 is no longer radially abutting the outer surface of the rotating lever 320, but the second roller 432 remains radially abutting the outer surface of the rotating lever 320. At this time, if the rotating rod 320 rotates in the forward direction, no friction exists between the rotating rod 320 and the first roller 431, the friction exists between the rotating rod 320 and the second roller 432, the friction between the rotating rod 320 and the second roller 432 will react with the second roller 432, the reacting friction is opposite to the direction of the second roller 432 abutting against the rotating rod 320, the reacting friction will drive the second roller 432 to move close to the first roller 431 against the elastic member 440, and at this time, the second roller 432 abutting against the outer surface of the rotating rod 320 will not limit the rotating rod 320 to rotate in the forward direction. On the basis of the above, if the rotating rod 320 rotates in the reverse direction, the friction force between the rotating rod 320 and the second roller 432 acts against the second roller 432, and the friction force acting against the second roller 432 is directed to the direction in which the second roller 432 abuts against the rotating rod 320, and since the second roller 432 is already abutting against the rotating rod 320, the friction force between the second roller 432 and the rotating rod 320 is always present, resulting in that the movement of the rotating rod 320 in the reverse direction is restricted.
With the first locking member 410 in the locked position and the second locking member 420 in the unlocked position, the second roller 432 is no longer radially abutting the outer surface of the rotating rod 320, but the first roller 431 remains radially abutting the outer surface of the rotating rod 320. At this time, if the rotating rod 320 rotates in the opposite direction, no friction exists between the rotating rod 320 and the second roller 432, the friction exists between the rotating rod 320 and the first roller 431, the friction between the rotating rod 320 and the first roller 431 will react with the first roller 431, the reacting friction is opposite to the direction in which the first roller 431 abuts against the rotating rod 320, the reacting friction will drive the first roller 431 to approach the second roller 432 against the elastic force of the elastic member 440, and at this time the first roller 431 abutting against the outer surface of the rotating rod 320 will not limit the rotating rod 320 to rotate in the opposite direction. On the basis of the above, if the rotating rod 320 rotates in the forward direction, the friction force between the rotating rod 320 and the first roller 431 acts against the first roller 431, and the friction force acting against the first roller 431 is directed in the direction in which the first roller 431 abuts against the rotating rod 320, and since the first roller 431 is already abutting against the rotating rod 320 and does not move, the friction force between the first roller 431 and the rotating rod 320 is always present, resulting in that the movement of the rotating rod 320 in the reverse direction is restricted.
For the first locking element 410 in the unlocked position and the second locking element 420 in the unlocked position, the first roller 431 and the second roller 432 are driven by the two cams, respectively, to approach each other, such that the first roller 431 and the second roller 432 no longer abut the outer surface of the rotation lever 320 in the radial direction. At this time, the rotation of the rotation lever 320 in the forward direction or the reverse direction is not limited by the two rollers.

When the first locking member 410 and the second locking member 420 are in the respective locking positions, the limiting members 430 are located at both ends of the transition section 312, and the first roller 431 and the second roller radially abut against the rotating rod 320 to limit the rotation of the rotating rod 320. The first roller 431 and/or the second roller 432 may be movable toward the middle region of the transition section 312 to radially disengage the rotating lever 320, thereby enabling bidirectional rotation or unidirectional rotation of the rotating lever 320 in the circumferential direction.
It should be appreciated that the transition section 312 may not be provided on the inner wall of the sleeve 310. The transition section 312 may also be disposed on the outer surface of the rotating rod 320, where the transition section 312 differs from the previous embodiment in that the radial dimension of the transition section 312 of the present embodiment is gradually reduced from both ends toward the middle to avoid two rollers.

The second locking element 420 further includes a second driving arm 423 connected to the second rotating wheel 422 and a second resetting element 424 connected to the second driving arm 423 and the sleeve 310, where the second driving arm 423 penetrates through the avoidance channel 313 and is exposed out of the sleeve 310, and the second driving arm 423 can overcome the resetting force of the second resetting element 424 to drive the second rotating wheel 422 and the second bump 421 to rotate forward and move to the unlocking position, so as to release the limitation of the reverse rotation of the rotating rod 320.
