When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present utility model.

[0041] The present utility model provides a photography auxiliary bracket assembly. Refer toFigures 1-5 , the photography auxiliary bracket assembly comprises:

[0042] A first connecting member 100, wherein the first connecting member 100 comprises a first connecting structure 110, wherein a first butting portion 111 is disposed at one axial end of the first connecting structure 110;

[0043] A second connecting member 200, wherein the second connecting member 200 comprises a second connecting structure 210, wherein the second connecting structure 210 is rotatably connected to the first connecting structure 110, wherein a second docking portion 211 adapted to the first docking portion 111 is provided at one axial end of the second connecting structure 210, wherein the second docking portion 211 is used to prevent the second docking portion 211 from rotating relative to the first connecting structure 110 when the second docking portion 211 is matched with the first docking portion 111, and to allow the second connecting structure 210 to rotate relative to the first connecting structure 110 when the second docking portion 211 is disengaged from the first docking portion 111;

[0044] A connecting rod 300, wherein the connecting rod 300 is disposed to connect the second connecting member 200 and the first connecting member 100, and when the connecting rod 300 rotates, the second docking portion 211 is driven to be separated from or docked with the first docking portion 111;

[0045] The knob 400 is slidably mounted on the connecting rod 300, or the connecting rod 300 is slidably mounted on at least a portion of the knob 400; the knob 400 is used to drive the connecting rod 300 to rotate under the action of an external force; the knob 400 has a first position away from the second connecting member 200, and a second position close to the second connecting member 200.

[0046] There are many ways to cooperate between the first docking portion 111 and the second docking portion 211. For example, the first docking portion 111 is a protrusion, and the second docking portion 211 is a groove arranged corresponding to the protrusion. The protrusion can be inserted into the groove along the direction of the connecting rod 300, which does not affect the movement of the first connecting structure 110 and can also limit the rotation of the first connecting structure 110 or the second connecting structure 210; the first docking portion 111 and the second docking portion 211 can also be structures such as magnets, suction cups, Velcro, etc., which can achieve a detachable connection while also fixing the position between the two.

[0047] When the connecting rod rotates, it drives the second docking portion 211 to disengage from or dock with the first docking portion 111. Exemplarily, a threaded hole 112 may be provided on the second connecting member 200, and a through hole 212 coaxial with the threaded hole 112 is provided on the first connecting structure 110. After the connecting rod 300 passes through the through hole 212, it is threadedly connected to the threaded hole 112. When the connecting rod 300 rotates, the connecting rod 300 will move axially relative to the first connecting structure 110, thereby driving the second connecting structure 210 to move with the connecting rod 300 until the second docking portion 211 and the first docking portion 111 are engaged in a snap-fit manner. There are various ways for the connecting rod 300 to drive the second connecting structure 210. For example, a protruding pushing portion is formed on the connecting rod 300 to abut against the second connecting structure 210, and then the second connecting structure 210 is driven to move when the connecting rod 300 moves axially; a ring-shaped protrusion may also be provided on the connecting rod 300, and a ring-shaped groove is provided on the second connecting structure 210 to cooperate therewith. While not affecting the rotational connection between the second connecting structure 210 and the connecting rod 300, the axially moving connecting rod 300 can also drive the second connecting structure 210 to move.

[0048] The materials of the knob 400 and the connecting rod 300 can be metal materials such as metal, aluminum alloy, stainless steel, etc., which have higher strength and are more durable; they can also be polymer materials such as plastic and rubber, which are lighter in weight and lower in cost. Moreover, the knob 400 and the connecting rod 300 can use different materials respectively and can be selected according to design requirements.

[0049] By adopting the method of sleeving the knob 400 on the connecting rod 300, since the knob 400 is on the outside, users can more easily push or pull the knob 400, reducing the operation difficulty. At the same time, the sleeving method makes it easier for the connecting rod 300 to rotate when the knob 400 rotates, and the rotation will not occupy too much space and affect other components. And most of the time, the connecting rod 300 is accommodated in the receiving groove of the knob 400, protected by the knob 400, reducing the influence of the external environment on the connecting rod 300, delaying the occurrence of rust, aging and other conditions as much as possible, and extending the service life of the photographic auxiliary support assembly.

[0050] It can be understood that to ensure that the knob 400 can drive the connecting rod 300 when rotating, the shapes of the inner side walls 410 of the connecting rod 300 and the knob 400 can be set as prismatic; or a sliding groove is provided on the outer surface of the connecting rod 300, and a sliding block is provided on the inner side wall 410 of the knob 400 and is accommodated in the sliding groove. When the knob 400 slides relative to the connecting rod 300, the sliding block can also slide in the sliding groove, so that when the knob 400 rotates, the sliding block on the knob 400 will drive the connecting rod 300 to rotate. The specific setting method can be selected according to design needs, and the present invention does not limit this.

[0051] Specifically, if it is necessary to lock the first connection structure 110 and the second connection structure 210, first pull the knob 400 to make the knob 400 slide on the connecting rod 300 to extend the length of the entire telescopic mechanism, and then rotate the knob 400 in the first direction, thereby driving the connecting rod 300 to rotate, and further driving the first connection structure 110 to move towards the second connection structure 210, and making the second docking portion 211 and the first docking portion 111 engage in a snap fit. At this time, the locking is completed. If it is necessary to release the first connection structure 110 and the second connection structure 210, rotate the knob 400 in the second direction to manually disengage the second docking portion 211 from the first docking portion 111. The first direction can be the clockwise direction or the counterclockwise direction, and the second direction is opposite to the first direction.

[0052] In the present utility model, by providing a knob 400 that can slide along the connecting rod 300, when the user needs to lock the first connection structure 110 and the second connection structure 210, only need to pull the knob 400 to make the overall length of the connecting rod 300 and the knob 400 longer, so as to obtain a larger operating space. The user can more conveniently rotate the knob 400 to drive the connecting rod 300 to rotate, reducing the operation difficulty of the user. Then, through the axial movement of the connecting rod 300 relative to the first connection structure 110, the second connection structure 210 is driven to approach the first connection structure 110 until the second docking portion 211 and the first docking portion 111 engage in a snap fit. At this time, the locking of the first connection structure 110 and the second connection structure 210 is completed. Rotating the knob 400 in the reverse direction can release the first connection structure 110 and the second connection structure 210. And when the user's operation is completed, the knob 400 can be pushed back to the initial position to avoid occupying too much space and improve portability. Moreover, most of the time, the connecting rod 300 is accommodated in the knob 400 and is protected by the knob 400, reducing the influence of the external environment on the connecting rod 300, and delaying the occurrence of rust, aging and other conditions as much as possible, and prolonging the service life of the photographic auxiliary support assembly.

[0053] In some embodiments, the first docking portion 111 includes a first locking portion, the second docking portion 211 includes a second locking portion, and the first locking portion and the second locking portion are engaged in a snap fit; or,

[0054] The first docking portion 111 has a first friction surface, the second docking portion 211 has a second friction surface, and the first docking portion 111 and the second docking portion 211 are in frictional cooperation.

[0055] Exemplarily, the first clamping portion may be a clamping hole, and the second clamping portion may be a clamping protrusion provided corresponding to the clamping hole. Through the cooperation between the clamping hole and the clamping protrusion, the limiting of the first connection structure 110 and the second connection structure 210 is realized, preventing relative rotation between the two. It can be understood that it may also be that the second clamping portion is a clamping hole and the first clamping portion is a clamping groove; or the first clamping portion and the second clamping portion are other common clamping structures, and the present invention does not limit this.

[0056] A first friction surface may also be provided on the first docking portion 111, and a second friction surface may be provided on the second docking portion 211. When the first docking portion 111 and the second docking portion 211 are in cooperation, the first friction surface contacts the second friction surface, and the friction between the two prevents relative rotation between the first connection structure 110 and the second connection structure 210.

[0057] Such as Figure 4 As shown, in some embodiments, the photography auxiliary bracket assembly further includes an elastic member 500. The elastic member 500 is disposed between the first connection structure 110 and the second connection structure 210, and the elastic member 500 is configured to: when the knob 400 drives the connecting rod 300 to rotate around the second direction, drive the second connection structure 210 to move to a state where the second docking portion 211 is disengaged from the first docking portion 111.

[0058] When the knob 400 rotates in the second direction, that is, when the connecting rod 300 is disengaged from the second connection structure 210, the elastic member 500 can push the second connection structure 210 to move away from the first connection structure 110, eliminating the need to manually separate the first connection structure 110 and the second connection structure 210, simplifying the operation steps and improving the user experience.

[0059] Such as Figure 4 As shown, in some embodiments, the first docking portion 111 is a first tooth portion 115 formed on an axial end face of the first connection structure 110;

[0060] The second docking portion 211 is a second tooth portion 215 formed on an axial end face of the second connection structure 210. The second tooth portion 215 is used to engage with the first tooth portion 115 to achieve the clamping cooperation between the second docking portion 211 and the first docking portion 111.

[0061] When locking is required, the connecting rod 300 drives the second connecting structure 210 to move towards the first connecting structure 110 until the first tooth part 115 and the second tooth part 215 are engaged, forming a stable mechanical connection between the two, so that the first connecting structure 110 and the second connecting structure 210 can be firmly fixed together, preventing rotation or sliding when subjected to external forces and ensuring the stability of the connection. When it is necessary to release the first connecting structure 110 and the second connecting structure 210, first rotate the knob 400 while driving the connecting rod 300 to rotate and move away from the first connecting structure 110. The second connecting structure 210 then moves away from the first connecting structure 110 under the action of the elastic member 500, thereby disengaging the first tooth part 115 and the second tooth part 215, facilitating the user to rotate the second connecting structure 210 for adjustment.

[0062] As Figure 6 and Figure 7 shown, in some embodiments, the first connecting member 100 includes a first arm 120 and a first connecting sleeve 114. The first connecting sleeve 114 is detachably connected to one end of the first arm 120 and forms the first connecting structure 110 with this end of the first arm 120. The connecting rod 300 is threadedly connected to the first connecting sleeve 114, and the first docking portion 111 is formed at one axial end of the first connecting sleeve 114;

[0063] The second connecting member 200 includes a second arm 220 and a second connecting sleeve 214. One end of the second arm 220 is rotatably connected to one end of the first arm 120. The second connecting sleeve 214 is detachably connected to one end of the second arm 220 and forms the second connecting structure 210 with this end of the second arm 220. The connecting rod 300 is rotatably connected to the second connecting sleeve 214, and the second docking portion 211 is formed at one axial end of the second connecting sleeve 214.

[0064] Among them, the first arm 120 and the second arm 220 can be used as connecting structures to directly connect other devices and equipment, or can be used as expansion structures to install additional connecting structures, so as to connect more devices and equipment. Taking the first arm 120 and the first connecting sleeve 114 as an example, the detachable connection method can be snap connection, pin connection, magnetic connection, clamp connection, suction cup connection, etc., and the present utility model does not limit this. Preferably, the present utility model adopts a relatively firm screw connection method. A first screw hole is provided on the first arm 120, a second screw hole is opened at the position corresponding to the first screw hole on the first connecting sleeve 114, and the first arm 120 and the first connecting sleeve 114 are fixed by screws connected to the first screw hole and the second screw hole. The setting method of the second arm 220 and the second connecting sleeve 214 is similar to that of the first arm 120 and the first connecting sleeve 114, and will not be elaborated here.

[0065] In some embodiments, the first arm 120 is used for detachably connecting to a photographic device, and the second arm 220 is used for detachably connecting to an extended power supply bracket.

[0066] The photographic equipment includes a camera and accessories such as a tripod, a flash, and a gimbal. Taking the connection of the first arm 120 to the photographic equipment as an example, there are multiple ways to connect the first arm 120 and the photographic equipment. A buckle or a slot can be set on the first arm 120 to adapt to the slot or buckle on the photographic equipment, and a detachable connection can be achieved by snapping; a third screw hole that can cooperate with the photographic equipment can also be set on the first arm 120, and the connection between the first connection structure 110 and the photographic equipment can be achieved by threaded connection; the first arm 120 can also be set as a clamping mechanism, and the photographic equipment can be grasped by the clamping claw to achieve a detachable connection. The present utility model does not impose any restrictions on this. Correspondingly, the connection method between the second arm 220 and the expansion power supply bracket is similar to the connection method between the second arm 220 and the photographic equipment, which will not be repeated here.

[0067] The first arm 120 and the second arm 220 both support detachable connection, making it easier to install and remove the photographic equipment or the extended power supply bracket, and the user can more easily connect the extended power supply to the photographic equipment, thereby charging the photographic equipment and ensuring the battery life of the photographic equipment. In this embodiment, the user can adjust the relative position between the photographic equipment and the extended power supply bracket according to specific needs, so that the user can better control the shooting or lighting angle or the placement of other equipment to adapt to different shooting scenes and light conditions.

[0068] like Figure 4 and Figure 8 As shown, in some embodiments, the connecting rod 300 includes a first rod body 310, a second rod body 320, a third rod body 330 and a fourth rod body 340 which are arranged in sequence, the first rod body 310 is threadedly connected to the first connecting member 100, the second rod body 320 is at least partially movably arranged in the second connecting member 200, the outer diameter of the third rod body 330 is greater than the outer diameter of the second rod body 320, and the end surface of the third rod body 330 facing the second rod body 320 is used to abut and drive the second connecting structure 210 to move when the connecting rod 300 rotates around the first direction;

[0069] The knob 400 is slidably connected to the fourth rod 340 and is used to drive the fourth rod 340 to rotate so as to drive the third rod 330 , the second rod 320 , and the first rod 310 to rotate.

[0070] Wherein the second connection structure 210 is sleeved on the second rod body 320, enabling the second connection structure 210 to rotate around the second rod body 320 to adjust the angle between the second connection structure 210 and the first connection structure 110. Specifically, when the connecting rod 300 rotates around the first direction, since the fourth rod body 340 is threadedly connected to the first connection structure 110, the entire connecting rod 300 moves axially. And because the outer diameter of the third rod body 330 is larger than the outer diameter of the second rod body 320, the second connection structure 210 sleeved on the second rod body 320 also moves towards the first connection structure 110 driven by the third rod body 330, and finally moves to the position where the first docking portion 111 and the second docking portion 211 are engaged, completing the locking of the first connection structure 110 and the second connection structure 210. The connecting rod 300 provided in stages facilitates the installation of other components and the connecting rod 300 together, reducing installation errors.

[0071] As Figure 8 shown, in some embodiments, a limiting protrusion 430 is provided on the inner side wall 410 of the knob 400. The outer diameter of the fourth rod body 340 is larger than the outer diameter of the third rod body 330. The end face of the fourth rod body 340 facing the third rod body 330 is used to abut against and limit the limiting protrusion 430 when the knob 400 slides in a direction away from the first connecting member 100 to prevent the knob 400 from slipping off the connecting rod 300.

[0072] Since the knob 400 needs to slide on the connecting rod 300, in order to prevent the knob 400 from directly coming off the connecting rod 300 during movement, a limiting protrusion 430 is provided on the inner side wall 410 of the knob 400, so that after the knob 400 moves a certain distance, the limiting protrusion 430 abuts against the fourth rod body 340 with an outer diameter larger than that of the third rod body 330, thereby blocking the knob 400 from continuing to move, realizing the limitation of the knob 400 and preventing the knob 400 from detaching from the connecting rod 300.

[0073] The shape of the limiting protrusion 430 can be selected according to design requirements. For example, the limiting protrusion 430 is set as a trapezoidal boss, which uses less material and has a lower cost; the limiting protrusion 430 can also be set as a ring to disperse the impact force generated when the limiting protrusion 430 collides with the fourth rod body 340 and improve the service life of the knob 400 and the connecting rod 300. Further, the limiting protrusion 430 is provided at the end of the knob 400, so that the distance between the limiting protrusion 430 and the fourth rod body 340 is larger when the knob 400 is not pulled, that is, the greater the distance the knob 400 can slide, the greater the value that the overall length of the knob 400 and the connecting rod 300 can reach, thereby further expanding the operation space of the user and enhancing the user experience.

[0074] As Figure 4 and Figure 9As shown, in some embodiments, the outer surface of the fourth rod body 340 includes at least one first plane 341, and a second plane 440 is provided on the inner side wall 410 of the knob 400 corresponding to the position of the first plane 341. The second plane 440 abuts against the first plane 341 for: driving the fourth rod body 340 to rotate therewith when the knob 400 rotates.

[0075] When the knob 400 rotates, due to the contact between the second plane 440 and the first plane 341, the rotational torque of the knob 400 can be directly transmitted to the fourth rod body 340, thereby realizing the rotation of the connecting rod 300. And the setting of the first plane 341 and the second plane 440 can help to accurately position the positional relationship between the knob 400 and the fourth rod body 340, ensure that they can be correctly aligned during assembly without deviation, and improve the assembly efficiency.

[0076] As Figure 8 shown, in some embodiments, the knob 400 further includes an inner bottom wall 420 connected to the inner side wall 410. A first magnetic member 450 is provided on the inner bottom wall 420, and a second magnetic member 342 is provided on the fourth rod body 340. The second magnetic member 342 is used for magnetic connection with the first magnetic member 450.

[0077] Since the knob 400 and the connecting rod 300 are in a sliding connection, in order to reduce the probability of the knob 400 moving by itself under the action of gravity or collision force, in this embodiment, a first magnetic member 450 is provided on the inner bottom wall 420, and a second magnetic member 342 is provided on the fourth rod body 340. The knob 400 and the fourth rod body 340 are fixed by magnetic connection. And when the inner bottom wall 420 of the knob 400 moves towards the fourth rod body 340 to a certain distance, the knob 400 will automatically move to a position close to the fourth rod body 340 under the action of magnetic force, reducing the operation time of the user and improving the operation efficiency.

[0078] The shapes and sizes of the first magnetic member 450 and the second magnetic member 342 can be determined according to design requirements. The first magnetic member 450 and the second magnetic member 342 can be respectively provided on the inner bottom wall 420 of the knob 400 and the fourth rod body 340 by bonding or clamping. Preferably, in this embodiment, the second magnetic member 342 is cylindrical, and a cylindrical groove is provided at the end of the fourth rod body 340 to accommodate and clamp the first magnetic member 450, realizing the detachable connection between the first magnetic member 450 and the fourth rod body 340, which is convenient for the user to clean and replace the first magnetic member 450.

[0079] As Figure 3 and Figure 8 shown, in some embodiments, one of the first magnetic member 450 and the second magnetic member 342 is a magnet, and the other is a magnet or a metal that can be adsorbed by the magnet.

[0080] Suitable materials can be selected according to design requirements. For example, when cost or weight control is required, an iron sheet can be used as the second magnetic attraction member 342. Iron sheets are usually cheaper and lighter than magnets. Therefore, when strong magnetic force is not required, iron sheets can be used to reduce cost and weight. When strong magnetic force is required, both the first magnetic attraction member 450 and the second magnetic attraction member 342 can be magnets, so as to provide strong magnetic force to prevent the knob 400 from moving by itself under the action of gravity or collision.

[0081] As Figures 4-7 As shown, in some embodiments, the first connecting member 100 is provided with a first groove 130, and the second connecting member 200 is correspondingly provided with a second groove 230 for the first groove 130. The elastic member 500 is sleeved on the connecting rod 300, and one end of the elastic member 500 is arranged in the first groove 130 and the other end is arranged in the second groove 230, for: when the knob 400 drives the connecting rod 300 to rotate around the second direction, driving the second connecting structure 210 to move to a state where the second docking portion 211 is disengaged from the first docking portion 111.

[0082] Exemplarily, taking the elastic member 500 as a spring, the spring is sleeved on the connecting rod 300, which reduces the space occupied by the elastic member 500 and limits the direction of deformation of the spring, reducing the probability of spring deformation, so that the elastic force direction of the spring always remains stable, ensuring the stability of the spring to push the second connecting structure 210 to move. The elastic member 500 can also be a rubber sleeve, a silica gel ring, etc. The present invention does not limit this. Further, one end of the elastic member 500 can merely be received in the second groove 230. When the second connecting structure 210 is at a certain distance from the first connecting structure 110, this end of the elastic member 500 can be disengaged from the second connecting structure 210, facilitating the user to replace the elastic member 500 in time when it is damaged. Or it can be controlled that one end of the elastic member 500 is clamped, adhered, welded, etc. to the second connecting structure 210, so that the elastic member 500 always maintains a connection with the second connecting structure 210 to provide stable elastic force. The connection of the elastic member 500 with the first connecting structure 110 is similar, and will not be elaborated here.

[0083] The above are only partial or preferred embodiments of the present invention. Neither the text nor the drawings can limit the protection scope of the present invention. All equivalent structural transformations made by using the content of the specification and drawings of the present invention under the overall concept of the present invention, or directly / indirectly applied in other related technical fields, are included in the protection scope of the present invention.
