Description

Technical Field

[0001] This invention relates to the field of photographic equipment technology, and in particular to a support device. Background Technology

[0002] Most tripods used in the photography industry can switch between folded and unfolded states. To illustrate, let's take a tripod as an example. When you need to use a tripod to support your equipment on a table or the ground, you can unfold the three legs. The unfolded legs provide more stable support for the equipment, ensuring high-quality footage. When the tripod is not in use, the legs can be folded for easy storage and transport.

[0003] Traditional tripods, when folded, result in an excessively long overall axial length, leading to a large space requirement and hindering efficient storage. To address this, patent CN211952186U discloses a selfie stick where multiple tripod components are housed within the handle assembly in the folded state, thus shortening the overall axial length. However, when switching from folded to unfolded, the multiple tripod components must first move axially a certain distance under the influence of the handle's base before unfolding, making the process cumbersome and time-consuming. Patent CN212583351U also discloses an independent support structure with a retractable bracket. The patent describes multiple legs that, in the folded state, flip and rest against the outer ring of the outer rod to shorten the overall axial dimension of the support structure in the folded state. However, when switching from the folded state to the unfolded state, multiple legs need to be manually disassembled one by one to fully unfold and hold each leg, which is very inconvenient for the user. Therefore, it is necessary to provide a support device that can shorten the folded size and facilitate opening. Summary of the Invention

[0004] The present invention provides a support device to address the problem of cumbersome opening of the support device in traditional solutions, which result in excessive axial length of the tripod when the legs are folded.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] This invention provides a support device, comprising:

[0007] A support tube having a first end and a second end disposed opposite to each other along the axial direction of the support tube;

[0008] The support frame includes multiple legs arranged circumferentially along the support tube, each leg having a fixed end rotatably connected to the first end in a folded state and a supporting end limited to the second end.

[0009] A driving component is disposed at the second end. The driving component is used to release the limiting position of the support end at the second end, so that the plurality of support ends automatically flip outward to the first end and are in an unfolded state.

[0010] In one embodiment, a torsion spring is provided between the fixed end and the first end, and the torsion spring in the folded state can release elastic force to drive the outward flip of the support leg.

[0011] In one embodiment, the support device further includes a rotating member rotatably disposed at the first end; when the support leg is in a folded state, the rotation of the rotating member relative to the first end is restricted by the support leg; when the support end is unfolded by flipping outward from the second end at a preset angle, the rotation restriction of the rotating member relative to the first end is released, and the rotating member can rotate instantaneously in the circumferential direction and limit the support leg to the unfolded state.

[0012] In one embodiment, the support device further includes a spring connected to the rotating member and the support tube. When the support leg is in a folded state, the spring stores elastic force. When the rotation restriction of the rotating member relative to the first end is released by the support leg, the spring can release the elastic force to instantly drive the rotating member to rotate circumferentially.

[0013] In one embodiment, the support tube includes a tube body and a seat body fixedly connected to the tube body. The side circumferential surface of the seat body is provided with mounting grooves corresponding to the number of support legs. The fixed end is rotatably connected to the mounting groove. The rotating component is provided with a plurality of notches that align with the mounting grooves. The rotating component is sleeved on the seat body and can rotate circumferentially relative to the seat body to misalign the notches and the mounting grooves, thereby limiting the support legs in the extended state.

[0014] In one embodiment, the drive member includes a traction member and an elastic member. The elastic member is axially disposed between the traction member and the support tube. When the outrigger is in a folded state, the support end is confined to the inside of the traction member. The traction member can overcome the elastic force of the elastic member and move axially relative to the support tube to release the support end.

[0015] In one embodiment, the support device further includes a central tube and a locking member. The central tube is axially disposed within the support tube, and the locking member is radially inserted through the support tube and radially movably disposed between the traction member and the central tube. The traction member is circumferentially rotatable so that both ends of the locking member abut against the traction member and the central tube, and the axial movement of the central tube is restricted by the locking member. The traction member can also circumferentially rotate to release the abutment state of both ends of the locking member, thereby releasing the restriction on the axial movement of the central tube.

[0016] In one embodiment, the support tube is provided with a movable groove, the movable groove including an axially extending first groove and a circumferentially extending second groove; the inner sidewall of the traction member is provided with a movable block and a clearance groove, the movable block being movably inserted through the movable groove; the traction member can move axially away from the first end in the first groove via the movable block to release the support end; after the traction member releases the support end, the traction member can also rotate circumferentially in the second groove via the movable block, and maintain the elastic member in a state of accumulating elastic force, so that the locking member is aligned with the clearance groove, thereby releasing the abutting state of the two ends of the locking member.

[0017] In one embodiment, the locking element includes radially arranged balls and locking rods, the balls being close to the traction element and the locking rods being close to the central tube.

[0018] In one embodiment, the support device further includes a power storage member disposed between the central tube and the support tube and capable of accumulating driving force. When the restriction on the axial movement of the central tube is released, the power storage member releases the driving force to drive the central tube to extend.

[0019] In one embodiment, the outer surface of the support tube is provided with grooves matching the number of legs, and the legs in the folded state are accommodated in the grooves.

[0020] As can be seen from the above technical solutions, the embodiments of the present invention have at least the following advantages and positive effects:

[0021] The support device of this invention has a first end of a support tube that can be supported on a table or ground surface, and a second end that can be used to mount shooting equipment or photographic aids. This allows the support tube to mount the shooting equipment or aids on the support surface, facilitating shooting operations. Since the multiple legs of the support frame are arranged side-by-side with the support tube when the support frame is folded, the overall axial dimension of the support device in the folded state is reduced, making it convenient for users to store when not in use. Furthermore, since the driving component can release the limiting position of the support end at the second end, when the user needs to use the support device again, they can operate the driving component to automatically flip the support end outwards to the first end and unfold it. Therefore, the support device of this invention can shorten its folded size and is easy to open. Attached Figure Description

[0041] First Embodiment

[0042] refer to Figure 1 and Figure 2 The present invention provides a support device 10, which is capable of supporting the device 10. Figure 1 The folding state shown and Figure 2 The shown deployment states are switched between each other. When the support device 10 is in the deployed state... Figure 1 When folded as shown, the support device 10 can be easily stored and carried. When the support device 10 is in the folded state... Figure 2 When unfolded as shown, the support device 10 is used to support a flat or uneven tabletop or ground. An adapter structure can be provided at the end of the support device 10 away from the tabletop or ground, allowing photographic equipment to be mounted on the support device 10 via the adapter structure. The adapter structure can be, but is not limited to, a quick-release mount, a threaded shaft, or a threaded hole, and the photographic equipment can be, but is not limited to, a camera, a mobile phone, a flash, or a fill light.

[0043] The support device 10 includes a support tube 100, a support frame 200, and a driving component 300. The support frame 200 is rotatably connected to the support tube 100, and the support frame 200 can... Figure 1 The folding state shown and Figure 2 The system switches between the unfolded states shown, when the support frame 200 is in... Figure 1 In the folded state shown, the support frame 200 and the support tube 100 are arranged side by side. When the support frame 200 is in the folded state... Figure 2 In the unfolded state, the support frame 200 and the support tube 100 are generally arranged along the axial direction. The driving component 300 is used to release the restraints of the support frame 200 in the folded state, allowing the support frame 200 to automatically unfold. Figure 1 The folded state shown has been switched to Figure 2 The unfolded state is shown.

[0044] The outer surface of the support tube 100 is provided with a groove 101 extending along the axial direction of the support tube 100. When the support frame 200 is in a folded state, the folded support frame 200 is accommodated in the groove 101. Furthermore, to ensure the integrity of the appearance of the support device 10 in the folded state, the outer surface of the support frame 200 is flush with the outer surface of the support tube 100. It should be understood that in other embodiments, the outer surface of the support tube 100 may not have a groove, in which case the folded support frame 200 is abutting against the support tube 100.

[0045] The support tube 100 has a first end 110 and a second end 120 arranged opposite each other along the axial direction of the support tube 100. The support tube 100 can be a hollow tube or a solid tube. A central tube 130 that extends axially relative to the support tube 100 can be provided inside the support tube 100. The free end 111 of the central tube 130 can be used to mount photographic equipment; for example, the free end 111 of the central tube 130 can be used to mount photographic equipment via a provided adapter structure. The central tube 130 can extend a reasonable length beyond the support tube 100 to change the overall axial length of the tube assembly formed by the support tube 100 and the central tube 130. This allows the user to adjust the photographic equipment mounted on the free end 111 of the central tube 130 to a reasonable height according to actual usage needs. It should be noted that in some usage scenarios where the height of the photographic equipment does not need to be adjusted, the support tube 100 may not have a relatively extendable central tube 130.

[0046] refer to Figure 3 and Figure 4 The support tube 100 includes a tube body 140 and a seat 150. The tube body 140 is provided with the second end 120 as described above. In this case, the central tube 130 of the support tube 100 can be understood as being located inside the tube body 140. The seat 150 is fixedly connected to the side of the tube body 140 away from the second end 120. The fixed connection between the seat 150 and the tube body 140 can be achieved using threaded fasteners. It should be understood that the tube body 140 and the seat 150 can also be integrally formed, making the support tube 100 a single unit. The side circumferential surface of the seat 150 is provided with a mounting groove 151. Figure 3 The illustration shows that there are multiple mounting slots 151, which are arranged at intervals along the circumference of the base 150. The mounting slots 151 are used to mount the support frame 200 so that the support frame 200 is rotatably connected to the mounting slot 151. In one embodiment, a limiting plate 152 is also provided on the side of the base 150 away from the tube 140. The limiting plate 152 can limit the support frame 200 from rotating excessively toward the inside of the support tube 100, thereby maintaining the support frame 200 at a large degree of extension.

[0047] The support frame 200 includes multiple legs 210 arranged circumferentially along the support tube 100, for example... Figure 2 The illustration shows that there are three support legs 210. It can be understood that in other embodiments, the number of support legs 210 can also be two or more. Each support leg 210 has a fixed end 211 and a supporting end 212 disposed opposite to each other. The fixed end 211 is rotatably connected to the first end 110, for example... Figure 3 The diagram illustrates that the fixed end 211 is rotatably connected to the mounting groove 151. Specifically, the fixed end 211 is provided with a rotating shaft 213 and a torsion spring 214. The rotating shaft passes through the fixed end 211 and the base 150, allowing the support leg 210 to rotate around the rotating shaft 213. Simultaneously, the torsion spring 214 is sleeved on the rotating shaft 213 and connected to the base 150. When the support leg 210 is in the folded state, the torsion spring 214 accumulates elastic force. When the driving component 300 releases the restriction of the support leg 210 in the folded state, the support leg 210 can automatically switch to the unfolded state under the action of the elastic force released by the torsion spring 214. It should be noted that when the support leg 210 is in the folded state, the support leg 210 can be accommodated in the groove 101.

[0048] The outrigger 210 is capable of rotating relative to the first end 110 with its fixed end 211, allowing the supporting end 212 to be switched to different positions according to the needs of the usage scenario. It should be noted that the outrigger 210 is capable of... Figure 1 In the folded state shown, the legs 210 are arranged side-by-side with the support tube 100, with the support end 212 of the legs 210 confined to the second end 120. Multiple legs 210 can also be extended apart to... Figure 2 The extended state shown allows the support frame 200 to be stably fixed to a flat or uneven tabletop or floor via multiple support legs 210.

[0049] A driving element 300 is disposed at the second end 120. The driving element 300 is used to release the restraint of the support end 212 at the second end 120, so that the multiple support ends 212 automatically flip outward to the first end 110 and are in an unfolded state. (Reference) Figure 3 and Figure 5 The driving component 300 includes a traction component 310 and an elastic component 320. The elastic component 320 is axially disposed between the traction component 310 and the support tube 100. The figure illustrates that the support tube 100 has an end cap 121 at its second end 120. The elastic component 320 is disposed between the traction component 310 and the end cap 121. The figure illustrates that the elastic component 320 is a spring, and there are multiple elastic components 320. The multiple elastic components 320 are arranged at circumferential intervals along the traction component 310 to ensure the uniform circumferential distribution of the elastic force accumulated by the elastic components 320. In other embodiments, the number of elastic components 320 may be one, or the elastic component 320 may be disposed at the center of the support tube 100. Additionally, the elastic component 320 may also be a spring sheet or an elastic pad.

[0050] When the outrigger 210 is in the folded state, the supporting end 212 of the outrigger 210 is confined to the inside of the traction member 310, for example... Figure 3 and Figure 5 The diagram illustrates that the traction member 310 is a ring, forming a receiving space 102 between the traction member 310 and the support tube 100. The traction member 310 is sleeved on the support tube 100 to confine the support end 212 within the traction member 310; that is, the traction member 310 confines the support end 212 within the receiving space 102. The traction member 310 can overcome the elastic force of the elastic member 320 and move axially relative to the support tube 100 to release the support end 212. For example... Figure 3 and Figure 5 The illustration shows the elastic element 320 positioned on the side of the traction member 310 away from the first end 110. In this case, the traction member 310 can move away from the first end 110 to compress the elastic element 320, allowing it to accumulate elastic force. It is understood that in other embodiments, the elastic element 320 can also be positioned on the side of the traction member 310 closer to the first end 110. In this case, the traction member 310 can move away from the first end 110 to stretch the elastic element 320, thereby allowing it to accumulate elastic force. It should be understood that the above explanation uses the example of the traction member 310 moving away from the first end 110 to release the support end 212 as an example. Of course, in other embodiments, the traction member 310 can also move towards the first end 110 to release the support end 212. Furthermore, it should be emphasized that after the support end 212 is released by the traction member 310, i.e., after the support end 212 disengages from the traction member 310, the support end 212 automatically flips and unfolds under the action of the torsion spring 214.

[0051] The support device 10 of this embodiment has a first end 110 of the support tube 100 that can be supported on a table or ground surface, and a second end 120 that can be used to mount shooting equipment or photographic auxiliary equipment. This allows the support tube 100 to mount the shooting equipment or photographic auxiliary equipment on the support surface, facilitating shooting operations. Since the multiple legs 210 of the support frame 200 are arranged side-by-side with the support tube 100 when the support frame 200 is in the folded state, the overall axial dimension of the support device 10 is reduced, making it convenient for users to store when not in use. Furthermore, since the driving member 300 can release the support end 100 from the second end 120 limit, when the user needs to use the support device 10 again, the driving member 300 can be operated to automatically flip the support end 100 outwards to the first end 110 and unfold it. Therefore, the support device 10 of this invention can shorten its folded size and is easy to open.

[0052] In one embodiment, reference Figure 3 and Figure 4The support device 10 also includes a rotating member 400, which is rotatably disposed at the first end 110. The figure illustrates that the rotating member 400 is a ring, and it is rotatably disposed relative to the support tube 100 on the base 150. When the support leg 210 is in a folded state, the rotation of the rotating member 400 relative to the first end 110 is restricted by the support leg 210. For example, the figure illustrates that the rotating member 400 is provided with multiple notches 401 that correspond to multiple mounting slots 151. The notches 401 and mounting slots 151 are in a one-to-one correspondence. In the folded state, the support leg 210 passes through at least the notches 401 to restrict the circumferential rotation of the rotating member 400 relative to the base 150. When the support end 212 unfolds by rotating outward from the second end 120 by a preset angle, that is, when the support end 212 unfolds outward from the second end 120 by a preset angle so that the support leg 210 just disengages from the notch 401, the rotation restriction of the rotating member 400 relative to the first end 110 is released, that is, the rotation restriction of the rotating member 400 relative to the base 150 is released. The rotating member 400 can rotate instantaneously in the circumferential direction, causing the notch 401 to be misaligned with the support leg 210, thus limiting the support leg 210 to the unfolded state. This can be understood as the rotating member 400 being able to prevent the support leg 210 from rotating towards the second end 120 through the notch 401.

[0053] To ensure that the rotating component 400 can complete the instantaneous rotation process in the circumferential direction, refer to Figure 6 In one embodiment, the support device 10 further includes a spring 500, which can be a torsion spring as shown in the figure. The spring 500 is connected to the rotating member 400 and the support tube 100. For example, the figure shows that the spring 500 is connected to the rotating member 400 and the seat 150. When the support leg 210 is in a folded state, the spring 500 is twisted and accumulates elastic force. When the rotation restriction of the rotating member 400 relative to the first end 110 is released by the support leg 210, that is, when the support end 212 is flipped outward from the second end 120 at a preset angle so that the support leg 210 just disengages from the notch 401, the spring 500 can release its accumulated elastic force and instantly drive the rotating member 400 to rotate circumferentially. It should be understood that the spring 500 may not be a torsion spring, but may also be a compression spring or a tension spring.

[0054] Second Embodiment

[0055] refer to Figure 7 and Figure 8 , Figure 7 This diagram illustrates the structure of the support device 10 in the folded state according to the second embodiment. Figure 8 This diagram illustrates the structure of the support device 10 in the unfolded state according to the second embodiment.

[0056] This embodiment has a structure that is basically the same as the support device 10 in the first embodiment. The difference is that the support device 10 in this embodiment can not only switch between a folded state and an unfolded state, but also, after the drive member 300 releases the support frame 200, the drive member 300 can be further rotated relative to the support tube 100, so that the central tube 130 can extend and retract axially relative to the support tube 100, thereby adjusting the overall height. It should be noted that the central tube 130 in this embodiment can automatically pop out and extend when the drive member 300 rotates relative to the support tube 100 to a certain angle. Of course, the central tube 130 can also be manually extended after unlocking.

[0057] refer to Figure 9 and Figure 10 In this embodiment, the support device 10 further includes a locking member 600, which is radially inserted through the support tube 100 and radially movably disposed between the traction member 310 and the central tube 130. In this embodiment, the locking member 600 is radially inserted through an end cap 121 provided at the end of the support tube 100. The top of the end cap 121 is further provided with a top cover 122, which is used to axially limit the locking member 600. Figure 8 The central tube 130 shown remains in an extended state when switched to... Figure 7 During the retraction of the central tube 130, the traction member 310 rotates circumferentially to cause the two ends of the locking member 600 to abut against the traction member 310 and the central tube 130. This increases the damping of the axial movement of the central tube 130, thereby restricting its axial movement by the locking member 600. Similarly, the traction member 310 can also rotate circumferentially to release the abutment of the two ends of the locking member 600, thus releasing the restriction on the axial movement of the central tube 130.

[0058] It should be noted that the locking member 600 in this embodiment includes radially arranged spheres 610 and locking rods 620. The spheres 610 are close to the traction member 310, and the locking rods 620 are close to the central tube 130. This means that when both ends of the locking member 600 abut against the traction member 310 and the central tube 130, the spheres 610 are used to abut against the traction member 310, and the locking rods 620 are used to abut against the central tube 130. Since the surface contact area of ​​the spheres 610 is small and the surface contact area of ​​the locking rods 620 is large, on the one hand, the locking member 600 abuts against the central tube 130 through the locking rods 620 with a larger contact area can ensure sufficient frictional damping to prevent the central tube 130 from moving axially; on the other hand, the locking member 600 abuts against the traction member 310 through the spheres 610 with a smaller contact area can reduce the driving force required for the operator to rotate the traction member 310.

[0059] refer to Figure 11 and Figure 12The support tube 100 is provided with a movable groove 103. In this embodiment, the movable groove 103 is provided on the end cap 121. The movable groove 103 includes an axially extending first groove 104 and a circumferentially extending second groove 105. The inner sidewall of the traction member 310 is provided with a movable block 311 and a clearance groove. The movable block 311 is movably inserted through the movable groove 103. The clearance groove can be understood as a recessed area on the inner side of the traction member 310, or the area where the clearance groove is located can be understood as an area with a larger radial dimension on the inner side of the traction member 310. The traction member 310 can move axially away from the first end 110 in the first groove 104 through the movable block 311 to release the support end 212. After the traction member 310 releases the support end 212, the traction member 310 can also rotate circumferentially in the second groove 105 through the movable block 311 to align the locking member 600 with the clearance groove, thereby releasing the abutment state of the two ends of the locking member 600. It should be noted that during the entire process of the movable block 311 passing through the second groove 105, the elastic element 320 can always maintain the state of accumulating elastic force. The elastic element 320 maintaining the state of accumulating elastic force can increase the rotational damping between the traction element 310 and the end cover 121, so as to prevent the traction element 310 from unexpectedly deflecting under external force after rotating at a preset angle relative to the end cover 121.

[0060] It should be noted that, in order to enable the central tube 130 to automatically pop out and extend when the driving member 300 rotates relative to the support tube 100 to a certain angle, the support device 10 in this embodiment also includes a power storage member 700 disposed between the central tube 130 and the support tube 100 and capable of accumulating driving force. When the restriction on the axial movement of the central tube 130 is released, the power storage member 700 releases the driving force to drive the central tube 130 to extend. The figure illustrates that the power storage member 700 is a spring; however, it can also be understood that the power storage member 700 could be an elastic pad.

[0061] The support device 10 of this embodiment has a first end 110 of the support tube 100 that can be supported on a table or ground surface, and a second end 120 that can be used to mount shooting equipment or photographic auxiliary equipment. This allows the support tube 100 to mount the shooting equipment or photographic auxiliary equipment on the support surface, facilitating shooting operations. Since the multiple legs 210 of the support frame 200 are arranged side-by-side with the support tube 100 when the support frame 200 is in the folded state, the overall axial dimension of the support device 10 is reduced, making it convenient for users to store when not in use. Furthermore, since the driving member 300 can release the support end 100 from the second end 120 limit, when the user needs to use the support device 10 again, the driving member 300 can be operated to automatically flip the support end 100 outwards to the first end 110 and unfold it. Therefore, the support device 10 of this invention can shorten its folded size and is easy to open. Furthermore, when the support frame 200 is folded and unfolded, and the drive member 300 can rotate circumferentially, the central tube 130 can be extended under the action of the energy storage member 700. The solution provided by the present invention can complete the unfolding action of the support frame 200, the limiting action of the support frame 200, and the limiting and releasing action of the axial extension and retraction of the central tube 130 by operating the same drive member 300, making the functionality more focused.

[0062] Although the invention has been described with reference to several typical embodiments, it should be understood that the terminology used is illustrative and exemplary, and not restrictive. Since the invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.

Claims

1. A support device, characterized in that, include: A support tube having a first end and a second end disposed opposite to each other along the axial direction of the support tube; The support frame includes multiple legs arranged circumferentially along the support tube. Each leg has a fixed end that is rotatably connected to the first end in a folded state and a supporting end that is limited to the second end. A torsion spring is provided between the fixed end and the first end. In the folded state, the torsion spring can release an elastic force to drive the leg to fold outward. A driving member is disposed at the second end. The driving member is used to release the limiting position of the support end at the second end, so that the plurality of support ends automatically flip outward to the first end and are in an unfolded state. The driving member includes a traction member and an elastic member. The elastic member is disposed axially between the traction member and the support tube. When the support leg is in a folded state, the support end is limited to the inside of the traction member. The traction member can overcome the elastic force of the elastic member and move axially relative to the support tube to release the support end. The support device further includes a central tube and a locking member. The central tube is axially disposed within the support tube, and the locking member is radially inserted through the support tube and radially movably disposed between the traction member and the central tube. The traction member is circumferentially rotatable so that both ends of the locking member abut against the traction member and the central tube, and the axial movement of the central tube is restricted by the locking member. The traction member can also circumferentially rotate to release the abutment state of both ends of the locking member, thereby releasing the restriction on the axial movement of the central tube. The support tube is provided with a movable groove, which includes a first groove extending axially and a second groove extending circumferentially. The inner sidewall of the traction member is provided with a movable block and a clearance groove, and the movable block is movably inserted through the movable groove. The traction member can move axially away from the first end in the first groove through the movable block to release the support end. After the traction member releases the support end, the traction member can also rotate circumferentially in the second groove through the movable block and maintain the elastic member in a state of accumulating elastic force, so that the locking member is aligned with the clearance groove, thereby releasing the abutting state of the two ends of the locking member.
