Description

Technical Field

[0001] This utility model relates to the field of photography accessories technology, and in particular to a one-click opening photography stand. Background Technology

[0002] Existing foldable tripods require manual unfolding of multiple legs relative to the platform to the desired angle during use, which is inconvenient and inefficient. To address these issues, existing technologies, such as Chinese patent CN221075984U, disclose an automatically pop-out tripod, which includes a pull rod assembly, a sliding sleeve assembly, support legs, an elastic reset component, a fixed base, a connecting rod, a connecting rod seat, and a locking structure. This automatically pop-out tripod achieves automatic opening of the support legs through the action of the elastic reset component, eliminating the need for manual unfolding.

[0003] However, in CN221075984U, the elastic reset element is directly compressed and released by the stop, pushing the sliding sleeve assembly. This direct action leads to unstable movement, easily causing vibration or jamming, thus affecting the automatic spring-out effect of the support legs and reducing the stability and reliability of the tripod. Moreover, its elastic reset element partially protrudes from the fixed base in its natural state, which not only affects the overall aesthetics of the tripod but also increases the risk of accidental damage to the elastic reset element. Utility Model Content

[0004] Therefore, it is necessary to provide a one-click opening photography tripod to address the problems of unstable movement and lack of aesthetics in existing automatic pop-up tripods.

[0005] A one-click camera tripod includes:

[0006] A main tube assembly includes an outer tube having a first end and a second end disposed opposite to each other along an axial direction;

[0007] A support bracket assembly includes a sliding sleeve, a mounting base, at least three legs, and a number of connecting rods equal to the number of legs. The sliding sleeve is slidably fitted onto the outer periphery of the outer tube. The mounting base is disposed at the second end of the outer tube. The first end of each leg is rotatably connected to the sliding sleeve. The first end of each connecting rod is rotatably connected to the inner side of each leg. The second end of each connecting rod is rotatably connected to the mounting base.

[0008] An elastic drive assembly includes a fixed sleeve, a push block, and a first elastic element. The fixed sleeve is fixed to the first end of the outer tube and has a receiving cavity. The push block is slidably disposed in the receiving cavity, and the end of the push block near the second end of the outer tube can extend out of the receiving cavity. The first elastic element is disposed in the receiving cavity and abuts against the push block.

[0009] A locking structure is provided at the second end of the outer tube, including a resettable button and a protrusion or recess that is linked to the button. The second end of the support leg is provided with a recess or protrusion that matches the shape of the protrusion or recess.

[0010] In the retracted state, the sliding sleeve compresses the push block to store energy in the first elastic element, and the protrusion is embedded in the recess. When the button is subjected to external force, the protrusion disengages from the recess, the first elastic element releases its elastic force to push the push block to move axially, and then the sliding sleeve and the connecting rod unfold each leg.

[0011] In one embodiment, the fixing sleeve includes a body and a bottom cover. The body is fixed to the first end of the outer tube. The body has a groove with an opening facing the second end of the outer tube. The bottom cover is connected to the end of the body near the second end of the outer tube. The bottom cover has an extension opening, and the push block extends out from the extension opening.

[0012] In one embodiment, the main body includes an inner cylinder, an outer cylinder, and a connecting portion. The inner cylinder is fixed to the outer periphery of the first end of the outer tube. The outer cylinder is sleeved around the outer side of the inner cylinder at a certain interval. The ends of the outer cylinder and the inner cylinder near the first end of the outer tube are connected by the connecting portion. The groove is formed between the inner cylinder, the outer cylinder, and the connecting portion. The end of the outer cylinder near the second end of the outer tube is connected to the bottom cover.

[0013] In one embodiment, the bottom cover has a first protruding edge that protrudes inward in a stepped manner at one end near the second end of the outer tube, and the protrusion is formed between the first protruding edge and the outer wall of the inner cylinder; the push block includes a cylindrical body and a second protruding edge, the second protruding edge is disposed at one end of the cylindrical body near the first end of the outer tube and protrudes outward in a stepped manner, and the first protruding edge cooperates with the second protruding edge to limit the movement of the push block.

[0014] In one embodiment, the end face of the bottom cover near the second end of the outer tube is closer to the second end of the outer tube than the end face of the inner cylinder near the second end of the outer tube.

[0015] In one embodiment, the first elastic element is a helical spring, which is sleeved on the inner cylinder.

[0016] In one embodiment, the support leg assembly further includes a second elastic element disposed between the first end of the leg and the sliding sleeve, or the second elastic element disposed between the first end of the connecting rod and the corresponding leg, or the second elastic element disposed between the second end of the connecting rod and the mounting base, or the second elastic element disposed between the sliding sleeve and the mounting base, for deploying the at least three legs after the protrusion disengages from the recess.

[0017] In one embodiment, the button is mounted on the mounting base and is movable along the axial direction of the outer tube. The locking structure further includes a first magnet and a second magnet, which are arranged opposite to each other along the axial direction of the outer tube and have opposite polarities. The first magnet is fixed to the button, and the second magnet is fixed to the mounting base.

[0018] In one embodiment, the button is mounted on the mounting base and is movable along the outer tube axial direction. The locking structure further includes a third elastic element, one end of which abuts against the button and the other end of which abuts against the mounting base.

[0019] In one embodiment, the main tube assembly further includes at least one retractable inner tube coaxially sleeved within the outer tube. The innermost inner tube has a cylindrical outer sleeve at its distal end, and an annular receiving cavity is formed between the outer sleeve and the outer tube. The radial dimension of the receiving cavity is adapted to the outer dimensions of the fixed sleeve. When in the retracted state, the inner tube retracts into the outer tube, the fixed sleeve is embedded in the receiving cavity, and the proximal end of the outer sleeve abuts against the end face of the sliding sleeve near the first end of the outer tube.

[0020] Compared with the prior art, the one-button opening camera bracket designed in this utility model has significant advantages in its elastic drive component (including a fixing sleeve fixed to the first end of the outer tube and its receiving cavity, a push block slidably disposed in the receiving cavity, and a first elastic element disposed in the receiving cavity and abutting against the push block):

[0021] Firstly, in the elastic drive assembly of this invention, the push block and the first elastic element are precisely guided and constrained within the fixed sleeve, ensuring that the push block moves along a stable, linear trajectory to transmit driving force. This indirect and guided driving method effectively overcomes the problems of motion instability, vibration, or jamming that may occur due to the direct action of the elastic element in the prior art. Therefore, this invention can significantly reduce vibration and impact during the driving process, avoid jamming, and make the automatic deployment process of the support leg assembly more stable, smooth, and reliable, which directly improves the operational stability of the entire device and the service life of the mechanism.

[0022] Secondly, the first elastic element of this invention is completely housed within the receiving cavity of the fixing sleeve. This means that regardless of whether the bracket is in the extended state (first elastic element extended) or the retracted state (first elastic element compressed), the first elastic element will not be exposed to the external environment. This built-in design, compared to the risks posed by the partially exposed elastic element in the prior art, effectively protects the first elastic element from damage caused by external dust, moisture, or accidental impacts, thereby extending its service life. Simultaneously, concealing the core drive component within the fixing sleeve also makes the overall appearance of the photography bracket more concise, aesthetically pleasing, and integrated, enhancing the overall quality and market competitiveness of the product.

When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The directional terms such as "front," "back," "up," and "down" are defined based on the location of the components in the accompanying drawings and their relative positions, and are merely for clarity and convenience in expressing the technical solution. It should be understood that the use of these directional terms should not limit the scope of protection claimed by this utility model.

[0078] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0079] Example 1:

[0080] This embodiment discloses a camera stand that can be opened with a single click. For example... Figure 1 As shown, the photography bracket mainly includes a main tube assembly 1, a support leg assembly 2, an elastic drive assembly 3, and a locking structure 4.

[0081] Supervisor Component 1:

[0082] The main support assembly 1 is the main support structure of the camera bracket, used to support photographic equipment (such as mobile phones). The main support assembly 1 includes an outer tube 12, which is cylindrical and has a first end 121 and a second end 122 arranged opposite each other along its axial direction. In this embodiment, the main support assembly 1 is a telescopic tube, which also includes multiple inner tubes 13 nested sequentially from the outside to the inside. The innermost inner tube 13, after extending outwards, has a cylindrical outer sleeve 14 (e.g., ...) at its end away from the first end 121 of the outer tube 12. Figure 2-4 (As shown). The inner diameter of the outer sleeve 14 is larger than the outer diameter of the fixing sleeve 31 of the elastic drive assembly 3. When the camera bracket is in the retracted state, the fixing sleeve 31 is housed within the outer sleeve 14, and the proximal end of the outer sleeve 14 abuts against the end face of the sliding sleeve 21 of the support leg assembly 2 near the first end 121 of the outer tube 12. This structure not only provides load-bearing capacity and height adjustment, but the design of its outer sleeve 14 also helps to achieve a more compact structure when retracted.

[0083] Support leg assembly 2:

[0084] The tripod assembly 2 is used to provide stable support for the camera bracket. The assembly includes a sliding sleeve 21, a mounting base 22, at least three legs 23, and a number of connecting rods 24 equal to the number of legs 23.

[0085] The sliding sleeve 21 is an annular sleeve that is slidably fitted around the outer circumference of the outer tube 12. The inner diameter of the sliding sleeve 21 is slightly larger than the outer diameter of the outer tube 12 to ensure that it can slide freely along the axial direction of the outer tube 12. A guide structure (not shown in the figure) is also provided between the sliding sleeve 21 and the outer tube 12, such as a guide groove extending axially on the outer wall of the outer tube 12, and a guide protrusion on the inner wall of the sliding sleeve 21 that cooperates with the guide groove to ensure smooth sliding and prevent relative rotation. The sliding sleeve 21 may include a sliding body 211 and an outer cover 212. The sliding body 211 is an annular structure that is slidably fitted around the outer circumference of the outer tube 12. The sliding body 211 is provided with a first arc-shaped groove (not shown in the figure). The outer cover 212 is an annular structure and is provided with a second arc-shaped groove (not shown in the figure). The first rotating shaft 231 is located in the shaft hole formed by the cooperation of the first and second arc-shaped grooves. The axial movement of the sliding sleeve 21 is the key to driving the extension and retraction of the outriggers.

[0086] The legs 23 are the support legs of the camera bracket, and there are at least three of them to ensure the stability of the bracket. The first end of each leg 23 is rotatably connected to the sliding sleeve 21 via a first pivot 231, allowing the leg 23 to be extended and retracted around the connection point on the sliding sleeve 21. The second end of the leg 23 is the end that rests on the support surface (such as the ground), and this second end is usually provided with an anti-slip pad (not shown in the figure) to increase friction with the ground. A shaft hole for connecting the connecting rod 24 is provided at a specific position on the inner side of the leg 23.

[0087] Mounting base 22 is disposed at the second end 122 of the outer tube 12. It serves as a fixed rotation fulcrum for the connecting rod 24 and supports the locking structure 4. Mounting base 22 may include a base 221 and a cover plate 222. The base 221 is fixed to the second end 122 of the outer tube 12 by a fixing structure, which may be a positioning hole provided at the second end 122 of the outer tube 12 and a positioning protrusion provided on the outer wall of the base 221. The base 221 is inserted into the second end 122 of the outer tube 12, and the positioning protrusion engages with the positioning hole. See [link to documentation]. Figure 4-6 The base 221 is provided with at least three third arc grooves arranged in the circumferential direction (not shown in the figure), and the cover plate 222 is provided with at least three fourth arc grooves arranged in the circumferential direction (not shown in the figure). The third rotating shaft 242 is located in the shaft hole formed by the cooperation of the third arc groove and the fourth arc groove.

[0088] The number of connecting rods 24 is the same as the number of legs 23. The first end of each connecting rod 24 is rotatably connected to the inner side of the corresponding leg 23 via a second rotating shaft 241, and the second end of each connecting rod 24 is rotatably connected to the mounting base 22 via a third rotating shaft 242. The function of the connecting rods 24 is to convert the axial movement of the sliding sleeve 21 into the synchronous and uniform unfolding or retracting movement of the legs 23 through a precise linkage mechanism. As an example, the first end of the connecting rod 24 is provided with a second rotating shaft 241, and the inner side of the leg 23 is provided with a shaft hole that mates with the second rotating shaft 241.

[0089] Elastic Drive Component 3:

[0090] The elastic drive assembly 3 provides the driving force for opening the camera bracket and is the core power source for achieving one-click deployment. This assembly includes a fixing sleeve 31, a push block 32, and a first elastic element 33.

[0091] The fixing sleeve 31 is fixed to the first end 121 of the outer tube 12 and has a receiving cavity. The fixing sleeve 31 can be fixed to the first end 121 of the outer tube 12 by means of threaded connection, snap-fit, or adhesive. Figure 2 , 3As shown, the fixing sleeve 31 may include a main body 311 and a bottom cover 312. The main body 311 is fixed to the first end 121 of the outer tube 12, and the main body 311 has a groove 313 with an opening facing the second end 122 of the outer tube 12. The bottom cover 312 is connected to the end of the main body 311 near the second end 122 of the outer tube 12, and the bottom cover 312 has an extension opening from which a pusher 32 extends. In another embodiment, as... Figure 3 As shown, the fixing sleeve 31 may include an inner cylinder 315, an outer cylinder 316, and a connecting portion 317. The inner cylinder 315 is fixed to the first end 121 of the outer tube 12. The outer cylinder 316 is located outside the inner cylinder 315. The ends of the outer cylinder 316 and the inner cylinder 315 near the first end 121 of the outer tube 12 are connected by the connecting portion 317, and the groove 313 is formed between the inner cylinder 315, the outer cylinder 316, and the connecting portion 317. The end of the outer cylinder 316 near the second end 122 of the outer tube 12 is connected to the bottom cover 312. Preferably, as shown... Figure 4 As shown, the bottom cover 312 has a first protruding edge 318 that protrudes inward in a stepped manner at one end near the second end 122 of the outer tube 12, and the protrusion is formed between the first protruding edge 318 and the outer wall of the inner cylinder 315.

[0092] The push block 32 is slidably disposed within the receiving cavity of the fixed sleeve 31, with one end of the push block 32 near the second end 122 of the outer tube 12 extending out of the receiving cavity (specifically, extending from the protrusion of the bottom cover 312), used to transmit driving force to the sliding sleeve 21. The shape of the push block 32 is adapted to the shape of the receiving cavity, ensuring that it can slide freely within the receiving cavity. Figure 4 As shown, the push block 32 may include a cylindrical body 321 and a second protruding edge 322. The second protruding edge 322 is disposed at the end of the cylindrical body 321 near the first end 121 of the outer tube 12 and protrudes outward in a stepped shape. The first protruding edge 318 cooperates with the second protruding edge 322 to limit the movement of the push block 32 and prevent the push block 32 from dislodging from the fixing sleeve 31 when it pops out.

[0093] The first elastic element 33 is disposed within the receiving cavity of the fixed sleeve 31 and abuts against the push block 32, for storing and releasing elastic potential energy. In this embodiment, the first elastic element 33 is preferably a helical spring, such as... Figure 3 and Figure 4 As shown, the helical spring is sleeved on the inner cylinder 315, with one end abutting against the inner wall of the connecting part 317 or the main body 311, and the other end abutting against the second protruding edge 322 of the push block 32.

[0094] Locking Structure 4:

[0095] The locking structure 4 is located at the second end 122 of the outer tube 12 and is used to lock the support leg assembly 2 in the retracted state to resist the thrust of the first elastic member 33. The locking structure 4 includes a resettable button 41 and a recess or protrusion (not shown in the figure) located at the second end of the support leg 23.

[0096] The button 41 has a locking feature, such as a protrusion 411 or a recess (not shown in the figure). The second end (or nearby) of the support leg 23 has a recess (not shown in the figure) or a protrusion (not shown in the figure) adapted to the shape of the protrusion 411 or recess for mechanical locking. In this embodiment, the button 41 is mounted on the mounting base 22 and can move axially along the outer tube 12. The button 41 includes a key base 412 and a keycap 413. The key base 412 has a through hole, through which a stud on the base 221 of the mounting base 22 passes. A screw (not shown in the figure) is screwed into the stud for guidance and limiting, allowing the key base 412 to slide axially relative to the base 221. The end of the key base 412 away from the second end 122 of the outer tube 12 has a central boss 414 and a protrusion 411 around the boss 414. The keycap 413 is connected to the boss 414.

[0097] The locking structure 4 also includes a third elastic element 42, one end of which abuts against the button 41 (e.g., the inner side of the key base 412) and the other end of which abuts against the mounting base 22 (e.g., the base 221). This third elastic element 42 provides a spring force after being pressed, causing the button 41 to automatically return to the locked position. The third elastic element 42 can be a coil spring or an elastic washer, etc.

[0098] Working principle:

[0099] like Figure 1 , 3 As shown in Figure 4, when the user pushes the sliding sleeve 21 upwards or retracts the support leg 23, the sliding sleeve 21 pushes the push block 32 to compress the first elastic element 33, causing it to store energy. At this time, the button 41 moves downwards under the elastic force of the third elastic element 42, and the protrusion 411 at its bottom is embedded in the corresponding recess at the second end (or nearby) of the support leg 23, forming a reliable mechanical lock and fixing the support leg 23 in the retracted state.

[0100] like Figure 7 and Figure 8As shown, when the camera bracket needs to be deployed, the user simply presses down on button 41 to overcome the elastic force of the third elastic element 42, causing button 41 to move upward. The protrusion 411 at its bottom disengages from the recess of the support leg 23, releasing the lock. At this time, because the first elastic element 33 is in a compressed state and stores elastic potential energy, it quickly releases the energy, pushing the push block 32 downward along the axial direction of the outer tube 12. The movement of the push block 32 causes the sliding sleeve 21 to slide downward. The sliding sleeve 21, through the linkage with the support leg 23 via the connecting rod 24, allows at least three support legs 23 to deploy outward synchronously and quickly. When the user releases button 41, the third elastic element 42 pushes button 41 downward to reset. This design achieves a convenient "one-button opening" function.

[0101] To further assist in the deployment of the support leg assembly 2 and ensure its smooth and complete deployment under various conditions, the assembly may also include a number of second elastic elements 25 equal to the number of connecting rods 24. The second elastic element 25 may be a torsion spring and may be located in multiple positions: for example, between the first end of the connecting rod 24 and the corresponding leg 23; or, between the second end of the connecting rod 24 and the mounting base 22; or, between the first end of the leg 23 and the sliding sleeve 21; or, between the sliding sleeve 21 and the mounting base 22. The second elastic element 25 provides an additional, auxiliary tension or torque during deployment, helping to overcome system friction and allowing the legs 23 to deploy more smoothly, quickly, and reliably under the drive of the first elastic element 33.

[0102] In one embodiment, the main tube assembly 1 further includes at least one retractable inner tube 13 coaxially sleeved within the outer tube 12. A cylindrical outer sleeve 14 is provided at the distal end of the innermost inner tube 13 (i.e., the end of the inner tube 13 furthest from it when it is extended). An annular receiving cavity is formed between the outer sleeve 14 and the outer tube 12, and the radial dimension of the receiving cavity is adapted to the outer dimensions of the fixing sleeve 31. When in the retracted state, the inner tube 13 retracts into the outer tube 12, the fixing sleeve 31 is embedded in the receiving cavity, and the proximal end of the outer sleeve 14 abuts against the end face of the sliding sleeve 21 near the first end 121 of the outer tube 12. This design allows the entire elastic drive assembly 3 to be stored within the outer sleeve 14 after folding, resulting in a more aesthetically pleasing appearance.

[0103] Example 2:

[0104] The main difference between this embodiment and Embodiment 1 is the reset method of button 41. This embodiment uses magnetic reset, aiming to provide a potentially simpler and more durable alternative.

[0105] like Figure 8As shown, the locking structure 4 in this embodiment includes a resettable button 41. The button 41 has a protrusion 411 or a recess, and the second end of the support leg 23 has a recess or protrusion that matches the shape of the protrusion 411 or recess. The button 41 is mounted on the mounting base 22 and can move axially along the outer tube 12. Unlike embodiment one, the locking structure 4 in this embodiment does not have a third elastic element 42, but instead includes a first magnet 43 and a second magnet 44. The first magnet 43 and the second magnet 44 are arranged opposite each other along the axial direction of the outer tube 12, and their opposite magnetic poles have the same polarity. The first magnet 43 is fixed to the button 41 (e.g., fixed inside the key base 412), and the second magnet 44 is fixed to the mounting base 22 (e.g., fixed at the corresponding position of the base 221).

[0106] Closed state:

[0107] Similar to Embodiment 1, in the retracted state, the sliding sleeve 21 compresses the push block 32, causing the first elastic element 33 to store energy. At this time, since the first magnet 43 and the second magnet 44 have the same polarity, they generate a repulsive force. This repulsive force automatically pushes the button 41 upward to the locked position, causing the protrusion 411 at its bottom to embed into the corresponding recess at the second end of the support leg 23, forming a mechanical lock and fixing the support leg 23 in the retracted state.

[0108] Expanded state:

[0109] When the camera bracket needs to be deployed, the user simply presses down on button 41 to overcome the repulsive force between the first magnet 43 and the second magnet 44, causing button 41 to move downwards and its bottom protrusion 411 to disengage from the recess of the support leg 23. At this time, the process of the first elastic element 33 driving the bracket to deploy is the same as in Embodiment 1. When the user releases button 41, (according to the logic in the original instruction manual) since there is still an attractive force between the first magnet 43 and the second magnet 44, this attractive force will pull button 41 upwards to reset. (Note: The reset force described here may contradict the physical principle of the attractive force and the aforementioned repulsive force locking mechanism or require specific design implementation; the original description is used here.)

[0110] This embodiment uses magnetic force instead of a spring to achieve button locking, retention, and reset, claiming advantages such as simple structure, potential reduction of mechanical fatigue, and improved reliability.

[0111] This invention, through the two embodiments described above, provides a camera stand that is easy to operate and can be opened with a single button. Its core lies in utilizing the energy stored in the elastic drive component, which is released by the user through a locking structure, thereby automatically unfolding the support tripod assembly. This design greatly improves the convenience for users when they need to quickly set up photographic equipment.

[0112] Through the above two embodiments, this utility model provides a camera stand that is easy to operate and can be opened with one click, greatly improving the user's convenience.

[0113] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
