[0050] In order to facilitate the understanding of the present application, the present application will be described in more detail below with reference to the relevant drawings. One or more embodiments of the present application are exemplarily shown in the drawings to make the understanding of the disclosed technical solutions of the present application more accurate and thorough. However, it should be understood that the present application can be realized in many different forms and is not limited to the embodiments described below.

[0051] As Figures 1 to 4As shown, a shooting auxiliary device according to an embodiment of the present invention can assist shooting equipment in shooting. The shooting equipment may include equipment for shooting and equipment for auxiliary shooting. The equipment for shooting may be a camera, a mobile phone, or a still camera. The camera includes a video camera and a camcorder. The equipment for auxiliary shooting may be a monitor, a photographic light, a microphone, a side handle, an upper handheld device, a hard disk bracket, a camera protective frame, and an adapter bracket. The shooting auxiliary device of the present invention may be a side handle 100. The side handle 100 is used for holding by hand to control shooting. The side handle 100 can be installed on the side of the camera protective frame (not marked). Taking the side handle 100 and the camera 200 as an example below, the camera 200 is installed in the camera protective frame (not marked). The side handle 100 is installed on the side of the camera protective frame through the connector 5. The upper handheld device 300 can be installed above the camera protective frame.

[0052] The shooting auxiliary device includes a device body and a rotating structure 20. The device body is equipped with the rotating structure 20 and can rotate about a pivot axis. The rotating structure 20 includes a sleeve 1, at least one locking assembly, at least one elastic member 3, an actuator 4, and a connecting member 5. The sleeve 1 is mounted on the device body. The locking assembly is mounted on the sleeve 1 to clamp or release one end of the connecting member 5. The other end of the connecting member 5 is fixedly connected to the shooting equipment. The elastic member 3 is elastically connected to the locking assembly. The actuator 4 is drivingly connected to the locking assembly.

[0053] Among them, when the starting member 4 is pressed, the locking assembly is unlocked and the connecting member 5 is released, so that the device body can be rotated to the corresponding position around the pivot axis, and the reset force generated by the elastic member 3 increases; after the starting member 4 is released, the locking assembly returns to the locked position under the action of the reset force of the elastic member 3, so that the locking assembly locks and fixes the connecting member 5, thereby preventing the device body from rotating around the pivot axis.

[0054] In this embodiment, the device body can be a handle body. During assembly, the side handle 100 is fixedly connected to the rotating structure 20. The rotating structure 20 can be rotatably connected to one end of the connecting member 5. The other end of the connecting member 5 can be assembled on the camera protective frame. The camera is installed in the camera protective frame. The locking assembly clamps the connecting member 5 to ensure the stability of the side handle 100 during shooting. When handheld shooting, the user controls the camera to shoot movies and videos by holding the side handle 100. When it is necessary to shoot mobile or shoot scenes from different angles, the user can press the trigger member 4 to drive the locking assembly to release the connecting member 5. After the user rotates the side handle 100 to a position suitable for shooting, the user releases the trigger member 4. The locking assembly returns to the locked position under the action of the restoring force of the elastic member 3 to clamp the connecting member 5 again, thereby preventing the side handle 100 from further rotation, thereby locking the rotating structure 20 to meet the user's need for further shooting. The structure is compact and occupies little space.

[0055] The sleeve 1 can be cylindrical, and an accommodation space (not shown) is formed inside the sleeve 1, which can be used to install the locking assembly. The sleeve 1 is also provided with a sliding groove 11 in the circumferential direction, which can be used to limit the locking assembly. The sleeve 1 can be made of metal, such as iron, steel, copper, or the like. The sleeve 1 also protects the locking assembly and makes the overall structure of the rotating structure 20 compact and integrated, which is convenient for transportation, storage and packaging;

[0056] The locking assembly is installed on the sleeve 1 and can clamp the connecting piece 5 to prevent the device body from rotating around the pivot axis, or can release the connecting piece 5 so that the device body can rotate around the pivot axis to a corresponding position. The corresponding position can be a position required by the user to rotate to meet the use needs. It can be understood that after the connecting piece 5 is assembled on the camera protection frame, the device body can be rotated around the pivot axis by holding the side handle 100.

[0057] The elastic member 3 is elastically connected to the locking assembly to clamp the connecting piece 5. The elastic member 3 can pull the locking assembly to maintain the clamping state of the connecting piece 5 by generating an elastic restoring force, that is, in the locked position. After the clamping state of the connecting piece 5 is destroyed (in the unlocked position), the elastic member 3 can pull the locking assembly back to clamp the connecting piece 5 by generating an elastic restoring force. The elastic member 3 can be any one of a tension spring, a compression spring, or a torsion spring. In this embodiment, a tension spring is taken as an example.

[0058] The starting member 4 is drivingly connected to the locking assembly to release the connecting piece 5. One end of the starting member 4 is provided with a pressing portion 41 which can extend out of the sleeve 1 to facilitate pressing and can be located at or near the position of the thumb when the side handle is held. The starting member 4 can be pivotally installed on the sleeve 1 to facilitate assembly and packaging, or the starting member 4 can be pivotally installed on the side handle 100 around the shaft 43. The starting member 4 can be a metal member and can be generally Z-shaped. The starting member 4 includes the pressing portion 41 and a driving portion 42.

[0059] In order to realize the locked or unlocked state of the locking assembly to clamp and fix or release the connecting piece 5, the locking assembly includes at least one rotating member. The rotating member is internally provided with a through accommodation groove (not shown), and the connecting piece 5 is rotatably accommodated in the accommodation groove. The rotating member also has a connecting portion 26. The elastic member 3 is elastically connected to the connecting portion 26 to lock the connecting portion 26 in the locked position, thereby locking and fixing the connecting piece 5. When the rotating member is rotated, the inner diameter of the accommodation groove increases or decreases to release or clamp the connecting piece 5. The starting member 4 is drivingly connected to the connecting portion 26.

[0060] In this embodiment, the elastic member 3 pulls the connecting portion 26 by generating an elastic restoring force to control the connecting portion 26 of the rotating member to be in the locked position of the sleeve 1. The locked position is the position where the connecting piece 5 is clamped and fixed by the locking assembly. The unlocked position is the position where the connecting portion 26 is away from the locked position, that is, the position where the locking assembly releases the connecting piece 5.

[0061] The rotating structure 20 is assembled in the locked state, the connecting part 26 is in the locking position, the connecting part 5 is clamped and fixed by the locking assembly, the side handle 100 cannot rotate relative to the connecting part 5, that is, the side handle 100 cannot rotate around the center axis as the pivot axis, the center axis of the embodiment is the center axis relative to the symmetrically formed main part of the rotating structure 20, and the center axis is located in the accommodating groove. The rotating part includes a handle part and a rotating part, the handle part protrudes with the connecting part 26, and the handle part and the rotating part can be inserted, interference fitted or clamped through the concave-convex structure, which is convenient for batch production and installation. The connecting part 5 can include a rotating rod 51 and a fixed part 52 connected to each other, one end of the rotating rod 51 is connected with the fixed part 52, the rotating rod 51 is partially accommodated in the accommodating groove, and the fixed part 52 can be connected with the camera protection frame through the locking part 53 for assisting shooting. The rotating rod 51 can be cylindrical, and the accommodating groove can also be circular to match the rotating rod 51. In some embodiments, the other end of the rotating rod 51 with the fixed part 52 can also be directly fixedly connected with the camera.

[0062] When the locking assembly needs to be unlocked, the connecting part 26 is driven to rotate by pressing the starting part 4 to unlock the locking assembly, that is, the connecting part 26 is driven to move from the locking position to the unlocking position to unlock the locking assembly, the inner diameter size of the accommodating groove is increased, so that the rotating part releases the connecting part 5, at this time, the tension spring is elongated, the restoring force generated is increased, after the angle of the side handle 100 is adjusted, the starting part 4 is released, and the restoring force generated by the retraction of the tension spring pulls the connecting part 26 back to the locking position to clamp and fix the connecting part 5, and at the same time, the connecting part 26 drives the starting part 4 back to the original position, that is, the locking position.

[0063] As shown in Figure 5 and Figure 6 , specifically, the locking assembly further includes at least one fixed part 27 and at least one rolling part 28, the fixed part 27 is fixed in the sleeve 1, and the rolling part 28 is circumferentially embedded on the rotating part, and the rotating part is rotatably installed in the fixed part 27. When the connecting part 26 is in the locking position, the rolling part 28 circumferentially clamps the connecting part 5, and when the connecting part 26 is in the unlocking position, the rolling part 28 releases the connecting part 5.

[0064] In the embodiment, as shown in Figure 10As shown, the rolling members 28 can rotate circumferentially on the rotating member, on the one hand, to make the rotating member rotate more labor-saving and flexible, and on the other hand, by rotating the rotating member, a plurality of rolling members 28 can simultaneously circumferentially hold the connecting member 5 to clamp the connecting member 5, and a plurality of rolling members 28 can also simultaneously circumferentially release the connecting member 5 to unlock the locking assembly; the rolling members 28 can be cylindrical rollers, and can be metal materials such as iron, copper or steel, etc. The rotating part of the rotating member is circumferentially provided with a vertical roller hole (not marked), one roller hole is provided with one rolling member 28, and the side wall of the roller hole is provided with a spring (not marked) to enable the rolling member 28 to rotate in the roller hole. The fixing member 27 is used to fix the rotating member, and the number of the two is matched.

[0065] Wherein, the direction of unlocking the locking assembly is defined as reverse, and the direction of locking the locking assembly is defined as forward, when the rotating member rotates forward, the rolling members 28 gradually gather towards the center axis of the accommodating groove, so that the inner diameter of the accommodating groove gradually decreases to clamp the connecting member 5, when the rotating member rotates reversely, the rolling members 28 move along the direction gradually away from the center axis of the accommodating groove, so that the rolling members 28 release the connecting member 5, and the inner diameter of the accommodating groove gradually increases. In other embodiments, the side wall of the rotating member can have elasticity, which can contract and expand to change the diameter size of the inner diameter of the rotating member. The wrench part of the rotating member can also be sleeved on one end of the rotating part, the other end of the rotating part is protruded, the wrench part and the rotating part can be gap-fitted with the inner wall of the fixing member 27, the fixing member 27 can be clamped in the sleeve 1, and the sleeve 1 also plays a protective role for the rotating member and the rolling members 28. The fixing member can be a metal member, in order to avoid wear caused by rigid connection between the fixing member 27 and the rotating member, the rotating member can be a plastic member.

[0066] When assembling, the connecting part 26 is in the locking position of the sleeve 1, and the rolling members 28 circumferentially hold the connecting member 5 to clamp and fix; when unlocking the locking assembly is needed, pressing the starting member 4 drives the connecting part 26 to drive the rotating member to rotate reversely in the accommodating space of the fixing member 27, the rotating member reversely rotating drives the rolling members 28 to gradually move away from the connecting member 5 along the inner wall of the fixing member 27 to release the connecting member 5, so that the rolling members 28 radially move away from the connecting member 5 to unlock the locking assembly, the connecting part 26 leaves the locking position, the connecting part 26 leaves the locking position, and then the rolling members 28 release the connecting member 5, after adjusting the angle of the side handle 100, releasing the starting member 4, the restoring force generated by the return spring pulls the connecting part 26 to drive the rotating member to rotate forward in the accommodating space of the fixing member 27, the rotating member rotates forward to drive the rolling members 28 to radially approach the connecting member 5 along the inner wall of the fixing member 27 to clamp the connecting member 5, the connecting part 26 returns to the locking position, and the locking assembly is in the locked state, the connecting part 26 pulls the starting member 4 to return to the initial position.

[0067] As Figure 7As shown, further, the inner diameter of the fixing member 27 is provided with a plurality of one-way grooves 271 arranged in sequence, the one-way grooves 271 matching a corresponding number of rolling members 28, the plurality of one-way grooves 271 being equidistantly arranged so that the inner diameter of the fixing member 27 forms a circular-arc step 272-shaped surrounding rolling track, the circular-arc step 272 being capable of blocking the rolling member 28 from rolling reversely, wherein, in the process of the elastic member 3 pulling the connecting part 26 back to the locking position, the rolling member 28 moves away from the circular-arc step 272 of the one-way groove 271 where it is located to clamp the connecting member 5, and is tangent to the bottom wall of the one-way groove 271 where it is located.

The equidistant arrangement of the one-way grooves 271 can ensure that each rolling member 28 rotates synchronously, the direction in which the rolling member 28 moves away from the circular-arc step 272 of the one-way groove 271 where it is located being the forward direction, and the direction in which the rolling member 28 moves towards the circular-arc step 272 of the one-way groove 271 where it is located being the reverse direction. The bottom wall of the one-way groove 271 has a curvature, and the distance between the bottom wall of the one-way groove 271 and the center axis gradually increases from the side with the circular-arc step 272 to the other side.
