Description
Technical Field
[0001] This utility model relates to the field of brackets, and in particular to camera brackets. Background Technology
[0002] In the field of photography and videography, especially in scenarios involving professional shooting, video production, or live streaming, support equipment such as cameras, fill lights, and microphones is frequently required. To flexibly adjust the position and angle of the equipment to meet different composition and lighting needs, various adjustable supports, such as tripods, light stands, and pan / tilt arms, are widely used. These supports typically include a base, a telescopic or foldable support arm, and connectors for attaching equipment. The multi-section structure of the arm and the movable joints at each connection point allow for multi-degree-of-freedom positioning in space.
[0003] In existing technologies, the core of achieving the folding function of the support arm and the rotation function of the connector lies in the pivot structure at each joint. Common multi-section folding arms typically use simple threaded hinges to connect adjacent arm sections and connectors, which has the following drawbacks:
[0004] 1. Under frequent folding and unfolding operations and loads, especially under the action of heavy equipment such as large fill lights or professional cameras, these types of hinges are prone to thread wear, stripping, or deformation of the connecting parts, which can lead to loosening of the joint, reduced locking force, or even failure. This can reduce the overall stability of the bracket and pose a risk of the equipment falling.
[0005] 2. When implementing the function of the connector rotating around its mounting axis (usually called the R-axis), existing solutions often lack effective damping adjustment or locking structures, resulting in the rotation process being either too stiff and difficult to fine-tune, or too loose and unable to be accurately positioned and maintained. Especially when the center of gravity of the equipment shifts, accidental rotation is likely to occur, affecting the stability and efficiency of shooting. Utility Model Content
[0006] In order to overcome the shortcomings of existing technical solutions, this utility model provides a camera bracket that can effectively solve the technical problems of easy damage and failure of the rotating shaft and the unsmooth rotation of the connector in the R-axis direction.
[0007] The technical solution adopted by this utility model to solve its technical problem is:
[0008] A camera bracket includes a base plate, a folding support arm, and a connector. The base plate and the connector are movably connected to both ends of the folding support arm. The base plate, the folding support arm, and the connector can all be flipped relative to each other. The folding support arm includes a fixed base, two or more rotating arms, and a pivot assembly. Adjacent rotating arms are connected end to end through the pivot assembly. Adjacent rotating arms can be flipped relative to each other. The first end of the first rotating arm is connected to the connector through the pivot assembly, and the last end of the last rotating arm is connected to the fixed base through the pivot assembly.
[0009] The rotating arm has connection holes at both ends. The connection holes of the two rotating arms are aligned. The rotating shaft assembly includes a tightening nut and a locking screw. The locking screw passes through the connection holes of the two rotating arms and is screwed to the tightening nut. The tightening nut and the locking screw clamp the side walls of the two rotating arms.
[0010] The connector includes a flip base, a rotary joint, and a damping plate. The flip base is rotatably connected to the rotary arm. A rotary shaft is provided at the end of the flip base away from the rotary arm. A limiting hole coaxial with the rotary shaft is provided in the middle of the rotary joint. The rotary joint is connected to the flip base through a limiting screw. The limiting screw passes through the limiting hole and is connected to the rotary shaft. The damping plate is located between the flip base and the rotary joint.
[0011] Furthermore, a cushioning pad is provided on the side of the base plate where the folding support arm is installed.
[0012] Furthermore, the fixed base is mounted to the surface of the base plate by fixing bolts.
[0013] Furthermore, a damping pad is provided between the two rotating arms that are connected end to end, and the damping pad is clamped between the opposite sides of the two rotating arms.
[0014] Furthermore, both the rotating arm and the fixed base are provided with hollowed-out sliding grooves, and auxiliary support arms are provided between adjacent rotating arms and between the rotating arm and the fixed base. The two ends of the auxiliary support arms are respectively connected to the sliding grooves of the two rotating arms.
[0015] Furthermore, the auxiliary support arm is provided with guide posts at both ends that slide along the slide groove. The end of the guide post away from the auxiliary support arm is provided with a fastening nut that is screwed to the guide post. The fastening nut and the support arm respectively press against both sides of the slide groove.
[0016] Compared with the prior art, the beneficial effects of this utility model are:
[0017] 1. A rotating shaft assembly consisting of a tightening nut and a locking screw connects adjacent rotating arms, the connector to the rotating arm, and the rotating arm to the fixed base. The locking screw passes through the aligned connecting hole and is screwed into the tightening nut. By tightening the nut, the side walls of the two rotating arms are directly clamped. This surface contact clamping method provides a strong and uniform locking force, greatly enhancing the joint's torsional resistance and load-bearing capacity. Even under high-frequency use or when bearing heavy equipment, it effectively prevents joint loosening, slippage, or thread damage, significantly improving the overall structural strength and reliability of the bracket and extending its service life.
[0018] 2. By coordinating the flip base, rotary joint, damping plate, rotating shaft, and limit screws, the rotation experience around the rotary joint's mounting axis has been specifically optimized. A damping plate is placed between the flip base and the rotary joint. This damping plate generates controllable frictional resistance, ensuring smooth operation while providing sufficient resistance torque as the rotary joint rotates around the mounting axis. This allows users to easily make fine-tuning adjustments to the angle, and once adjusted, the position is firmly held, effectively preventing accidental rotation due to the equipment's own weight or slight contact, greatly improving the accuracy and stability of the equipment's positioning.

Detailed Implementation
[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] Example 1:
[0031] like Figure 1-5 As shown, the camera bracket includes a base plate 1, a folding support arm, and a connector 2. The base plate 1 and connector 2 are movably connected to both ends of the folding support arm. The base plate 1, folding support arm, and connector 2 can all be flipped relative to each other. The base plate 1 can be fixedly connected to other devices or a base. A buffer pad 3 is provided on the side of the base plate 1 where the folding support arm is installed. When the folding support arm is fully folded and stored, it will come into contact with the buffer pad 3. The buffer pad 3 can effectively absorb the impact force of collisions and prevent the folding support arm from directly impacting the hard base plate 1, thereby avoiding noise, surface scratches, and accidental deformation or damage to the end of the arm during storage, improving the durability of the bracket and the storage experience.
[0032] The folding support arm includes a fixed base 4, three rotating arms 5, and a pivot assembly 6. Adjacent rotating arms 5 are connected end-to-end via the pivot assembly 6, allowing for relative flipping. The first end of the first rotating arm 5 is connected to the connector 2 via the pivot assembly 6, and the last end of the last rotating arm 5 is connected to the fixed base 4 via the pivot assembly 6. The fixed base 4 is mounted to the surface of the base plate 1 using fixing bolts. This connection method is simple and reliable. The preload of the fixing bolts ensures a firm connection between the fixed base 4 and the base plate 1, effectively resisting torsional loads during use and preventing the base from loosening or shifting. Simultaneously, the bolt connection facilitates disassembly, making it convenient to replace the base plate 1, repair the base, or adjust the overall structure. The rotating arm 5 has connection holes 501 at both ends. The connection holes 501 of the two rotating arms 5 are aligned. The rotating shaft assembly 6 includes a tightening nut 601 and a locking screw 602. The locking screw 602 passes through the connection holes 501 of the two rotating arms 5 and is screwed to the tightening nut 601. The tightening nut 601 and the locking screw 602 clamp the side walls of the two rotating arms 5. By tightening the nut, the side walls of the two rotating arms 5 are directly clamped. This surface contact clamping method provides a strong and uniform locking force, which greatly enhances the joint's torsional resistance and load-bearing capacity. Even under high-frequency use or when bearing heavy equipment, it can effectively prevent joint loosening, slippage, or thread damage, significantly improving the overall structural strength and reliability of the bracket and extending its service life.
[0033] A damping pad 7 is provided between the two rotating arms 5 that are connected end to end. The opposing sides of the two rotating arms 5 clamp the damping pad 7. When the two rotating arms 5 are clamped by the pivot assembly 6, their relative contact surfaces will simultaneously clamp the damping pad 7 located between them. This damping pad 7 significantly increases the frictional damping when adjacent rotating arms 5 rotate relative to each other. On the one hand, it makes the folding and unfolding movements of the rotating arms 5 smoother and more stable, avoiding any looseness and improving the operating feel. On the other hand, after adjustment, the additional friction provided by the damping pad 7 helps resist external forces, such as equipment vibration or slight touches, enhancing the self-locking ability of the joint and further improving the stability and reliability of the bracket positioning.
[0034] The connector 2 includes a flip base 201, a rotary joint 202, and a damping plate 203. The flip base 201 is rotatably connected to the rotating arm 5. A rotating shaft 211 is provided at the end of the flip base 201 away from the rotating arm 5. A limiting hole 212 coaxial with the rotating shaft 211 is provided in the middle of the rotary joint 202. The rotary joint 202 is connected to the flip base 201 by a limiting screw 204. The limiting screw 204 passes through the limiting hole 212 and is connected to the rotating shaft 211. The damping plate 203 is located between the flip base 201 and the rotary joint 202. Through the cooperation of the flip base 201, the rotary joint 202, the damping plate 203, the rotating shaft 211, and the limiting screw 204, the rotation experience of the equipment around the mounting shaft of the rotary joint 202 is specially optimized. The damping plate 203 is provided between the flip base 201 and the rotary joint 202. The damping plate 203 generates controllable frictional resistance, ensuring smooth operation and providing sufficient resistance torque as the rotary joint 202 rotates around the mounting axis. This allows users to easily make fine-tuning adjustments to the angle and securely maintain the position once adjusted, effectively preventing accidental rotation due to the equipment's own weight or slight contact, and greatly improving the accuracy and stability of the equipment's positioning.
[0035] Example 2:
[0036] like Figure 4-9As shown, this embodiment is based on Embodiment 1. Both the rotating arm 5 and the fixed base 4 are provided with hollowed-out sliding grooves 502. An auxiliary support arm 8 is provided between adjacent rotating arms 5 and between the rotating arm 5 and the fixed base 4. The two ends of the auxiliary support arm 8 are connected to the sliding grooves 502 of the two rotating arms 5, respectively. Guide posts 9 that slide along the sliding grooves 502 are provided at both ends of the auxiliary support arm 8. A fastening nut 10, screwed to the guide post 9, is provided at the end of the guide post 9 away from the auxiliary support arm 8. The fastening nut 10 and the support arm respectively press against both sides of the sliding groove 502. By providing the auxiliary support arm 8 and its connecting structure, an additional triangular support structure is constructed between adjacent rotating arms 5. The two ends of the auxiliary support arm 8 slide within the hollowed-out sliding grooves 502 of the arm body or base via the guide posts 9 and are finally locked and positioned by the fastening nut 10. When the support extends and carries the equipment, the auxiliary support arm 8 can effectively share the bending moment acting on the rotating arm 5, significantly reducing the bending deformation of the arm body. The triangular support structure significantly enhances the structural rigidity and integrity of the entire folding support arm assembly in its extended state, reducing swaying under load. Once the auxiliary support arm 8 is locked, it physically constrains the relative angles between adjacent arms, helping to resist any minor deformation or loosening that may occur in the pivot assembly 6 and ensuring the joint angle remains stable under heavy loads. By sliding the guide post 9 within the groove 502 and tightening the fastening nut 10, different arm extension angles can be flexibly accommodated, and the support state at that angle can be quickly locked, reducing the load pressure on the pivot assembly 6.
[0037] The guide posts 9 at both ends of the auxiliary support arm 8 can slide smoothly within the slide groove 502 to adapt to changes in the arm angle. By tightening the fastening nuts 10, they press against the two side plates of the slide groove 502, respectively, forming a reliable clamping and fixing. This connection method ensures that the connection point between the auxiliary support arm 8 and the rotating arm 5 or the fixed base 4 is firm and without wobbling, effectively transmitting the supporting force. This is a key technical guarantee for achieving the enhanced rigidity and stability of the auxiliary support arm 8. At the same time, the position of the support point can be easily adjusted by loosening the fastening nuts 10, making operation convenient.
[0038] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
