Description

Technical Field

[0001] This utility model relates to the field of photographic and video equipment technology, and in particular to a folding bracket and a softbox. Background Technology

[0002] With the continuous development of photography and videography technology, the requirements for lighting effects are becoming increasingly stringent. In order to achieve better lighting effects, modern large photography and videography lights are usually equipped with photography accessories such as diffusers.

[0003] Currently, diffusers typically have an umbrella-shaped reflective surface, thus occupying a relatively large area when unfolded. To meet the needs of transportation and storage, diffusers are designed with a foldable structure to conceal the umbrella ribs.

[0004] However, the existing softbox folding structure is quite complex. If the umbrella ribs need to be unfolded or folded, specific tools or cumbersome operations are required. It is clear that it can no longer meet the needs of some fast-paced shooting scenarios and affects the user experience. Utility Model Content

[0014] The first curved section is connected to the flip plate, and the end of the second umbrella rib is connected to the second curved section; when the flip plate is in the open position, the connection between the first umbrella rib and the mounting plate and the connection between the second umbrella rib and the second curved section are located on the same circumferential plane.

[0015] In some embodiments of this application, the locking assembly includes a locking groove disposed on the mounting plate, a locking fastener disposed on the flip plate, and a snap-fit ​​member movably disposed in the mounting plate; the locking groove is disposed on one side surface of the mounting plate opposite to the first umbrella rib, the locking fastener has a locking slot, and when the flip plate is in the open position, the locking fastener is accommodated in the locking groove; the snap-fit ​​member moves relative to the mounting plate so that the end of the snap-fit ​​member can extend into the locking groove and engage with the locking slot of the locking fastener accommodated in the locking groove, or exit from the locking groove and release the engagement with the locking slot of the locking fastener.

[0016] In some embodiments of this application, two snap-fit ​​components are provided, and the two snap-fit ​​components can be relatively close to or far apart from each other;

[0017] Two locking slots and two locking fasteners are provided respectively. When the two locking fasteners are far apart, the locking fasteners can be locked into the locking slots of the locking fasteners housed in the locking slots. When the two locking fasteners are close together, the ends of the locking fasteners can be disengaged from the locking slots of the corresponding locking fasteners to exit the locking slots, thereby releasing the flip plate from the locking of the mounting plate.

[0018] In some embodiments of this application, the folding bracket further includes a spring, and each of the snap-fit ​​members is connected to the inner wall of the mounting plate by a spring, and the end of the snap-fit ​​member away from the spring is used to snap with the lock slot of the locking device;

[0019] When an external force drives the two latching members to approach each other, the spring is elastically compressed, and the end of the latching member can disengage from the lock opening of the corresponding locking device to exit the locking groove; when the external force is released, the spring is elastically extended, allowing the two latching members to move away from each other, so that the end of the latching member can extend into the locking groove to engage with the lock opening of the locking device.

[0020] In some embodiments of this application, the folding bracket further includes a pusher, one end of which is connected to the snap-fit ​​member, and the other end of which is disposed outside the mounting plate; the end of the pusher disposed outside the mounting plate is used to be subjected to an external force to drive the snap-fit ​​member to move relative to the mounting plate.

[0021] In some embodiments of this application, when the flip plate is in the open position, the pusher is located inside the projection surface of the flip plate.

[0022] In some embodiments of this application, the folding bracket further includes two flip seats, which are disposed opposite to each other on the surface of the mounting plate, and each flip seat is provided with a shaft hole;

[0023] The flip plate is arc-shaped, and both ends of the flip plate are provided with rotating shafts; the rotating shafts at both ends of the flip plate are respectively inserted into the shaft holes of the two flip seats, so that the flip plate can rotate relative to the mounting plate.

[0024] In some embodiments of this application, the bracket body further includes a torsion spring, and the first umbrella ribs are rotatably connected to the mounting plate via the torsion spring.

[0025] This utility model also provides a diffuser, which includes an umbrella surface, a diffuser cloth, a chuck, and the aforementioned folding bracket. The umbrella surface is connected to the first umbrella rib and the second umbrella rib. The inner surface of the umbrella surface forms a reflective surface that can reflect light. The diffuser cloth is connected to and covers the opening of the umbrella surface. The chuck is disposed on the surface of the mounting plate opposite to the flip plate and is used to connect to a photography / videography light.

[0026] In some embodiments of this application, the chuck is detachably connected to the surface of the mounting plate opposite to the flip plate; and / or,

[0027] The chuck includes a connecting body, locking blocks, and a raised edge. The connecting body is a cylindrical structure with open ends and a hollow interior.

Detailed Implementation

[0043] Typical embodiments embodying the features and advantages of this utility model will be described in detail in the following description. It should be understood that this utility model can have various variations in different embodiments, all of which do not depart from the scope of this utility model, and the descriptions and illustrations therein are for illustrative purposes only and not intended to limit this utility model.

[0044] In the description of this application, it should be understood that, in the embodiments shown in the accompanying drawings, the indications of direction or positional relationships (such as up, down, left, right, front, and back) are merely for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

If the description of the positions of these elements changes, these directional indications also change accordingly.

[0045] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0046] See Figures 1 to 4 One embodiment of this application provides a folding bracket 100 that can connect to a camera light and a lighting accessory. The lighting accessory can be a reflective cloth, a diffuser cloth, etc., and can process the light emitted by the camera light.

[0047] The folding bracket 100 enables the opening and folding of the light effect accessory. The folding bracket 100 includes a bracket body 10, a flipping body 20, and a locking component.

[0048] Specifically, the support body 10 includes an annular mounting plate 11 and first umbrella ribs 12 rotatably connected to the mounting plate 11. The mounting plate 11 has through holes 110 for light to pass through. The first umbrella ribs 12 are used to connect the umbrella surface 200, and the aforementioned light effect accessories can be made into the structure of the umbrella surface 200. Multiple first umbrella ribs 12 are provided, and the multiple first umbrella ribs 12 are arranged at intervals on the side near the mounting plate 11.

[0049] The flip-up body 20 includes a flip-up plate 21 and second umbrella ribs 22 connected to the flip-up plate 21. The second umbrella ribs 22 are used to connect the umbrella canopy 200, and two or more second umbrella ribs 22 are provided and spaced apart from each other on the flip-up plate 21. The flip-up plate 21 is rotatably connected to the surface of the mounting plate 11, having an open position and a folded position relative to the mounting plate 11. A locking assembly is disposed between the mounting plate 11 and the flip-up plate 21, and the locking assembly is used to lock the flip-up plate 21 in the open position. When the flip-up plate 21 is in the open position, the second umbrella ribs 22 are arranged near the side of the mounting plate 11 opposite to the first umbrella rib 12, and the second umbrella ribs 22 together with the first umbrella rib 12 form an umbrella-shaped structure for opening the umbrella canopy 200.

[0050] In some embodiments of this application, the number of second umbrella ribs 22 may be less than the number of first umbrella ribs 12. This arrangement allows the umbrella surface 200 to be opened and closed with a small number of umbrella ribs, which can directly reduce the amount of material used in the folding bracket and achieve a lightweight design of the folding bracket 100.

[0051] Furthermore, the numerous first umbrella ribs 12 can serve as the main load-bearing structure, while the fewer second umbrella ribs 22 can serve as auxiliary support. During the opening and closing of the umbrella canopy 200, the fewer second umbrella ribs 22 can reduce the inertia of movement, making it easier for the folding bracket 200 to unfold or fold along the preset direction, improving the smoothness of operation, and making it easier for users to use.

[0052] The locking assembly locks the flip panel 21 in the open position, fixing it to the surface of the mounting plate 11 opposite to the first umbrella rib 12. When the locking assembly releases the flip panel 21, it rotates relative to the mounting plate 11 to the folded position, allowing it to fold over onto the surface of the mounting plate 11 where the first umbrella rib 12 is located. The second umbrella rib 22 is positioned close to the side of the mounting plate 11 where the first umbrella rib 12 is located, causing the umbrella canopy 200 to fold up.

[0053] For the folding bracket 100 of this application, when the flip plate 21 is rotated to the folded position, the second umbrella rib 22 is arranged on the same side as the first umbrella rib 12, which allows the umbrella surface 200 to be folded up, thereby significantly reducing the overall size of the folding bracket 100, making it easier for users to carry and move, especially suitable for outdoor shooting, mobile scenes, or environments with limited space. Furthermore, by unlocking and locking the flip plate 21 through the locking assembly, users can quickly switch the flip plate from the folded position to the open position, allowing the umbrella surface 200 connected to the first umbrella rib 12 and the second umbrella rib 22 to open rapidly, effectively shortening preparation time before shooting, improving work efficiency, and enhancing the user experience.

[0054] In some embodiments of this application, combined with Figure 5As shown, the mounting plate 11 of the bracket body 10 is generally circular. The mounting plate 11 has a through hole 110, and when the folding bracket 100 is used in conjunction with a camera light, the light emitted by the camera light can pass through the through hole 110.

[0055] The mounting plate 11 is provided with a plurality of first umbrella ribs 12, which are used to connect the umbrella canopy 200. The plurality of umbrella ribs are arranged on one side near the mounting plate 11 and are spaced apart along the circumference of the mounting plate 11. In some examples, the mounting plate 11 may be provided with a plurality of limiting cavities 14, and each first umbrella rib 12 is disposed in a limiting cavity 14. The end of the first umbrella rib 12 abuts against the inner wall of the limiting cavity 14, and the inner walls of the limiting cavity 14 corresponding to the abutment of the first umbrella rib 12 are arranged at an included angle.

[0056] Each first umbrella rib 12 has an end set in an independent limiting cavity 14, and the inner walls on both sides of the limiting cavity 14 form an angle. This arrangement uses geometric limiting to ensure that the end of the first umbrella rib 12 is in close contact with the inner wall of the limiting cavity 14, so as to effectively restrict the radial and circumferential movement of the first umbrella rib 12 in the unfolded state, avoid the loosening or angular displacement of the first umbrella rib 12 due to external force, and ensure that the position of the umbrella surface 200 connected to the first umbrella surface 200 is fixed.

[0057] Furthermore, when the user folds the umbrella canopy 200, the inner wall of the limiting cavity 14, which is arranged at an angle, can guide the first umbrella ribs 12 to rotate along a specific trajectory, avoiding interference or jamming between the multiple first umbrella ribs 12 during the folding process, ensuring smooth folding action, and at the same time making the first umbrella ribs 12 fit tightly against the mounting plate 11 after folding, further reducing the storage volume of the folding bracket 100, making it convenient for users to use and carry.

[0058] In some examples, the support body 10 may also include a torsion spring 15, through which the first umbrella rib 12 is rotatably connected to the limiting cavity 14 of the mounting plate 11.

[0059] During installation, the torsion spring 15 can be pre-loaded with torque, ensuring that the first umbrella rib 12 is always subjected to an elastic force at the apex of the angle between the umbrella canopy 200 and the inner wall of the limiting cavity 14 after the umbrella canopy 200 is opened. This pre-tension effectively counteracts any loosening of the umbrella canopy 200 caused by external forces, maintaining the tension of the umbrella canopy 200. Furthermore, when the umbrella canopy 200 is opened, the elastic potential energy stored in the torsion spring 15 drives the first umbrella rib 12 to automatically spring open to a preset angle along the angled surface of the limiting cavity 14, achieving rapid and automatic opening of the umbrella canopy 200.

[0060] In some embodiments of this application, the folding bracket 100 may further include a flip seat 40, which is disposed on the surface of the mounting plate 11. The flip plate 21 is rotatably connected to the mounting plate 11 via the flip seat 40.

[0061] The surface of the mounting plate 11 is provided with two flip seats 40, which are arranged opposite to each other. The flip plate 21 is arc-shaped, and its two ends are rotatably connected to the surface of the mounting plate 11 through a flip seat 40. Each flip seat 40 is provided with a shaft hole 41, and each end of the flip plate 21 is provided with a rotating shaft 211. The rotating shafts 211 at both ends of the flip plate 21 pass through the shaft holes 41 of the two flip seats 40, so that the flip plate 21 can rotate relative to the mounting plate 11.

[0062] The two opposing flip seats 40 can provide symmetrical rotation fulcrums for the flip plate 21, ensuring that the flip plate 21 is subjected to uniform force during rotation, avoiding tilting, jamming or structural deformation caused by unilateral force, and improving the stability of the connection and rotation of the flip plate 21.

[0063] A second umbrella rib 22 for fixing the umbrella canopy 200 is connected to the flip plate 21, which is arc-shaped. This arrangement allows the flip plate 21 to fit against the edge of the mounting plate 11 when rotated to the open position, ensuring that the second umbrella rib 22 and the first umbrella rib 12 together form a complete umbrella structure, thus ensuring the uniformity of the light processing effect of the umbrella canopy 200. Furthermore, when the flip plate 21 is rotated to the folded position, its arc-shaped design allows it to fit close to the surface of the mounting plate 11, reducing the overall volume of the folding bracket 100 and improving portability.

[0064] In this application, the flip plate 21 is rotatably disposed on the surface of the mounting tray 11, having an open position and a folded position relative to the mounting tray 11. When the flip plate 21 is rotated to the open position, the flip plate 21 can fit against the surface of the mounting tray 11, and the second umbrella rib 22 and the first umbrella rib 12 on the flip plate 21 are respectively located on both sides of the mounting tray 11; when the flip plate 21 is rotated to the folded position, the flip plate 21 can fit against the surface of the mounting tray 11, and the second umbrella rib 22 on the flip plate 21 is arranged near the side of the mounting tray 11 where the first umbrella rib 12 is located.

[0065] In some implementations of this application, combined with Figure 1 , Figure 2 as well as Figure 6 As shown, the flipping body 20 may include a connecting seat 24, and each second umbrella rib 22 is connected to the flipping plate 21 through a connecting seat 24.

[0066] The connecting seat 24 includes a straight rod section 241 and a first bent section 242 and a second bent section 243 respectively connected to both ends of the straight rod section 241. The first bent section 242 and the second bent section 243 are respectively disposed on both sides of the straight rod section 241, and both the first bent section 242 and the second bent section 243 are bent and connected to the straight rod section 241.

[0067] The first curved section 242 is connected to the flip plate 21, and the end of the second umbrella rib 22 is connected to the second curved section 243. When the flip plate 21 is in the open position, the connection between the first umbrella rib 12 and the mounting plate 11 and the connection between the second umbrella rib 22 and the second curved section 243 are located on the same circumferential plane.

[0068] When the flip plate 21 is in the open position, the connection points of the first umbrella rib 12 and the mounting plate 11, and the connection points of the second umbrella rib 22 and the second curved section 243, are located on the same circumferential plane, so that the ends of all umbrella ribs form an arc-shaped profile symmetrical along the light emission axis of the light source in space. This arrangement ensures that the umbrella surface 200 is a regular circle or ring after unfolding, avoiding uneven light reflection caused by the umbrella surface 200 failing to form a uniform umbrella shape due to misalignment of the umbrella ribs. This ensures that the umbrella surface 200 handles light more evenly, improving the accuracy and quality of light processing in photography and videography.

[0069] Furthermore, the connecting seat 24 enables the installation position of the second umbrella rib 22 to form a set angle relative to the flip plate 21, which, together with the circumferential spacing of the first umbrella rib 12 on the mounting plate 11, ensures that the spacing of all umbrella ribs in the circumferential direction is uniform, further ensuring that the tension of the umbrella surface 200 is consistent and avoiding deviations in light processing caused by local slack or tightness.

[0070] In some examples, such as Figure 5 As shown, the interior of the flip plate 21 may be provided with multiple positioning cavities 212. Each second umbrella rib 22 is disposed in a positioning cavity 212, and the connecting seat 24 to which the second umbrella rib 22 is connected abuts against the inner wall of the positioning cavity 212. The inner walls on both sides of the positioning cavity 212 corresponding to the abutment of the connecting seat 24 are arranged at an angle.

[0071] When the second umbrella rib 22 is installed into the positioning cavity 212 via the connecting seat 24, the angled inner wall of the positioning cavity 212 can abut against and restrict the radial movement and circumferential rotation of the connecting seat 24 through the inclined surface, so that the second umbrella rib 22 is fastened in the open state of the umbrella surface 200, avoiding loosening or angular displacement caused by the vibration of the camera lamp, external force collision or the tension of the umbrella surface 200, effectively ensuring the positional accuracy and structural stability of the umbrella surface 200.

[0072] In some examples, combined Figure 3 and Figure 5 As shown, when the flip plate 21 is in the open position, the edge of the flip plate 21 extends outward beyond the edge of the mounting plate 11.

[0073] This arrangement allows the second umbrella rib 22 to be positioned further outward on the mounting plate 11 relative to the first umbrella rib 12 when the flip panel 21 is opened. This increases the unfolding radius of the umbrella surface 200 supported by the first and second umbrella ribs 12, directly expanding the coverage area of ​​lighting accessories such as diffusers and reflectors. This allows the light emitted by camera lights to cover a larger shooting area after diffusion. Furthermore, the portion of the flip panel 21 extending beyond the mounting plate 11 is easy for the user to grip, facilitating rotation of the flip panel 21 relative to the mounting plate 11.

[0074] Furthermore, in this application, the folding bracket 100 also includes a locking assembly disposed between the mounting plate 11 and the flip plate 21, the locking assembly being used to lock the flip plate 21 in the open position.

[0075] In some embodiments, such as Figure 2 , Figure 7 as well as Figure 8 As shown, the locking assembly may include a locking groove 13, a locking member 23, and a snap-fit ​​member 30. Specifically, the mounting plate 11 has a locking groove 13 on one side surface opposite the first umbrella rib 12, and the flip plate 21 has a locking member 23 with a locking slot 231. When the flip plate 21 is in the open position, the locking member 23 is accommodated in the locking groove 13.

[0076] The snap-fit ​​member 30 is movably disposed in the mounting plate 11. The snap-fit ​​member 30 moves relative to the mounting plate 11 so that the end of the snap-fit ​​member 30 can extend into or exit from the locking groove 13. When the locking member 23 is received in the locking groove 13, the end of the snap-fit ​​member 30 can snap and fix in the locking slot 231 of the locking member 23 so that the flip plate 21 can be locked onto the mounting plate 11.

[0077] When the flip panel 21 is rotated to the open position, the locking fastener 23 can be accommodated in the locking groove 13 of the mounting plate 11. The groove contour constrains the angle and position of the flip panel 21, forming the initial positioning and fixing of the flip panel 21, and realizing the unfolding of the umbrella surface 200. Combined with the setting of the snap-fit ​​30 moving so that its end extends into the locking groove 13 and snaps into the locking mouth 231 of the locking fastener 23, the flip panel 21 can be completely locked on the mounting plate 11, so that the rotational freedom of the flip panel 21 is completely restricted. Even if subjected to lateral tension, wind force or equipment vibration, the rigid support of the snap-fit ​​30 can prevent the flip panel 21 from rotating or folding accidentally, which is especially suitable for outdoor shooting and other scenarios that require high stability.

[0078] Furthermore, the movable design of the latch 30 allows users to easily lock or release the flip panel 21. Before shooting, simply turn the flip panel 21 to the open position, and the locking pin 23 automatically falls into the locking groove 13. The latch 30 moves and engages with the lock 231 to complete the locking. When the umbrella surface 200 needs to be folded, the reverse operation can be performed to quickly unlock it, effectively improving the efficiency of equipment use and making it suitable for scenarios such as photography and live streaming that require frequent adjustments.

[0079] In some other embodiments of this application, the locking groove 13 may be disposed on the flip plate 21, the locking fastener 23 may be disposed on the mounting plate 11, and the snap-fit ​​member 30 may be movably disposed inside the flip plate 21. When the flip plate 21 is in the open position, the locking fastener 23 is accommodated in the locking groove 13. The snap-fit ​​member 30 moves relative to the flip plate 21 so that the end of the snap-fit ​​member 30 can extend into the locking groove 13 and engage with the locking port 231 of the locking fastener 23 accommodated in the locking groove 13, or exit from the locking groove 13 and disengage from the locking port 231 of the locking fastener 23.

[0080] In other examples, the locking fastener 23 can be omitted, the locking groove 13 can be placed on the flip plate 21, and the latching member 30 can be movably placed on the mounting plate 11. The latching member 30 can move relative to the mounting plate 11, and its end can extend from the surface of the mounting plate 11 or retract into the interior of the mounting plate 11. When the end of the latching member 30 extends from the surface of the mounting plate 11, it engages with the locking groove 13, thereby locking the flip plate 21 in the open position. When the end of the latching member 30 retracts into the interior of the mounting plate 11, it disengages from the locking groove 13, thereby releasing the lock on the flip plate 21 and allowing it to rotate relative to the mounting plate 11.

[0081] The following description uses the example of locking groove 13 being provided on mounting plate 11, locking fastener 23 being provided on flip plate 21, and snap fastener 30 being movably provided on mounting plate 11. However, the solution of the other embodiment is not limited, and the relevant structure can be adapted accordingly.

[0082] In some examples, there are two connectors 30, both of which are movably disposed in the mounting plate 11 so that the two connectors 30 can be relatively close to or far apart.

[0083] The mounting plate 11 has two locking slots 13 and two locking fasteners 23 on the flip plate 21. When the two locking pieces 30 are far apart, they can be locked into the locking openings 231 of the locking fasteners 23 housed in the locking slots 13. When the two locking pieces 30 are close together, the ends of the locking pieces 30 can disengage from the locking openings 231 of the corresponding locking fasteners 23 to exit the locking slots 13, thereby releasing the flip plate 21 from the locking of the mounting plate 11.

[0084] Each locking member 30 can be locked with the corresponding locking groove 13 and locking member 23 to achieve a stable lock on the flip plate 21. Furthermore, the two locking members 30 can convert the torque into symmetrical pressure on the mounting plate 11, avoiding structural distortion or fatigue fracture of the locking member 30 caused by eccentric load due to single-point locking, thus ensuring the stability of the overall structure.

[0085] like Figure 8 and Figure 9 As shown, in this example, the folding bracket 100 also includes a spring 50, and each snap-fit ​​30 is connected to the inner wall of the mounting plate 11 by a spring 50. The end of the snap-fit ​​30 away from the spring 50 is used to snap into the locking slot 231 of the locking fastener 23.

[0086] When an external force drives the two latching pieces 30 to approach each other, the spring 50 is elastically compressed, allowing the ends of the latching pieces 30 to disengage from the locking slots 231 of the corresponding locking fasteners 23 and exit the locking grooves 13. When the external force is released, the spring 50 elastically extends, allowing the two latching pieces 30 to move away from each other, so that the ends of the latching pieces 30 can extend into the locking grooves 13 and engage with the locking slots 231 of the locking fasteners 23.

[0087] After the external force is released, the spring 50 releases its elastic potential energy to automatically reset the latching member 30 to the locked state. The preload of the spring 50 ensures that the latching member 30 maintains a locked tendency when not in operation, preventing unlocking due to vibration or accidental contact, and significantly improving the reliability of the overall structure.

[0088] like Figure 7 As shown, the folding bracket 100 also includes a pusher 60, one end of which is connected to the snap-fit ​​member 30, and the other end of which is disposed outside the mounting plate 11. The end of the pusher 60 disposed outside the mounting plate 11 is used to be subjected to external force to drive the snap-fit ​​member 30 to move relative to the mounting plate 11.

[0089] When it is necessary to unlock the flip plate 21 on the mounting plate 11 and switch the flip plate 21 from the open position to the folded position, the user only needs to hold the two pushers 60 with his / her fingers and bring the two pushers 60 closer together, which will drive the two latches 30 to move relative to each other and disengage from the lock slots 231 of the corresponding locking fasteners 23.

[0090] The pusher 60 is located outside the mounting plate 11 and can be driven by pinching with fingers (such as thumb and forefinger), conforming to ergonomic design. Users can unlock and unlock the device simply by relative finger movements without the need for tools or complex actions. When external force is applied by the fingers, the pusher 60 causes the latch 30 to compress the spring 50, allowing the latch 30 to quickly exit the locking groove 13, thereby releasing the lock on the flip plate 21. After the external force is released, the elastic restoring force of the spring 50 drives the latch 30 to automatically reset and engage in the lock slot 231, allowing the flip plate 21 to be relocked without additional operation.

[0091] In this example, when the flip plate 21 is in the open position, the pusher 60 is located inside the projection surface of the flip plate 21. This arrangement can prevent the umbrella 200 from mistakenly turning to the folded state due to accidental contact with the pusher 60 by a foreign object when the umbrella 200 is open, thus ensuring the stability of the umbrella 200 in the open state.

[0092] Furthermore, such as Figure 10 As shown, one embodiment of this application also provides a diffuser 1000, which includes an umbrella surface 200, a folding bracket 100, a diffuser cloth (not shown in the figure), and a chuck 300. The structure of the folding bracket 100 has been described above and will not be repeated here. The umbrella surface 200 is connected to the first umbrella rib 12 and the second umbrella rib 22, and the inner surface of the umbrella surface 200 forms a reflective surface capable of reflecting light.

[0093] By connecting the umbrella surface 200 to the folding bracket 100, the umbrella surface 200 can be quickly unfolded from its stored state to its working state, which can be operated by a single person and is suitable for the needs of quick lighting setup on shooting locations. In addition, the folding bracket 100 has a compact overall size when folded, making it suitable for outdoor shooting, mobile shooting, and other scenarios that require frequent carrying of equipment.

[0094] The umbrella surface 200 is unfolded by the folding bracket 100. The reflective surface of the inner surface of the umbrella surface 200 can reflect and diffuse the direct light emitted by the light source, soften the high-intensity light, reduce the strong light spots and harsh shadows in the picture, and make the light distribution more uniform. It is especially suitable for scenes in portrait and product photography where the softness of light is required, and effectively ensures the image quality of photography and videography.

[0095] In addition to the reflective umbrella surface 200 shown in this application, in other examples, the umbrella surface 200 can also be a diffuser. When the light emitted by the light source passes through the diffuser, the direct light can be scattered into uniform and soft diffused light, thereby enhancing the soft texture of the captured image.

[0096] Alternatively, the inner surface of the umbrella 200 can be fitted with a smooth or frosted transparent plastic plate. This plastic plate can transform a point light source into a surface light source, avoiding localized overexposure caused by concentrated light spots, making it suitable for scenes in photography where high highlight uniformity is required. Alternatively, the inner surface of the umbrella 200 can be fitted with a black honeycomb grid structure. This honeycomb grid structure blocks stray light from the edges, allowing reflected or transmitted light to be output at a narrow angle, reducing unnecessary lighting on the background or surrounding environment. Alternatively, the inner surface of the umbrella 200 can be fitted with color filters. Different colored filters can balance the color temperature of the light source and add color tones to the light, creating diverse shooting atmospheres and meeting a wide range of user needs.

[0097] A diffuser is installed at the opening of the umbrella surface 200, covering the opening. The light emitted by the photography and video lights can be reflected by the reflective surface of the umbrella surface 200 and then softened by the diffuser, making the emitted light softer and improving the shooting effect.

[0098] See some examples in this application. Figure 11 and Figure 12 The diffuser 1000 also includes a chuck 300, which is detachably attached to the surface of the mounting plate 11 on the side opposite to the flip plate 21. The chuck 300 is used to connect to a camera light.

[0099] The chuck 300 and mounting plate 11 are detachably connected, allowing the diffuser 1000 to be compatible with a variety of photography and video equipment. When connecting to different photography and video equipment, simply replacing the chuck 300 with the corresponding specification will ensure compatibility with different brands or models of lights, expanding the range of applications of the diffuser 1000 and meeting the diverse needs of users in various scenarios.

[0100] In this example, the chuck 300 includes a connecting body 301, a locking block 302, and a raised edge 303. The connecting body 301 is a cylindrical structure with open ends and a hollow interior. Multiple locking blocks 302 are provided, and the multiple locking blocks 302 are spaced apart at the edge of one end of the opening of the connecting body 301. The locking blocks 302 are used to engage with a camera lamp.

[0101] The raised edge 303 is annular and is located at the opening at the other end of the connecting body 301. The mounting plate 11 has a mounting groove 111 on the surface opposite to the flip plate 21, and the raised edge 303 is located in the mounting groove 111.

[0102] Multiple spaced locking blocks 302 on the chuck 300 can engage with the bayonet structure of photographic and video lights, enabling quick installation and removal of the diffuser 1000 from the light fixture. In use, the user simply aligns the locking block 302 with the light fixture interface and rotates or presses it; the locking mechanism, either through elastic deformation or mechanical locking, completes the process without tools, significantly improving operational efficiency.

[0103] In some examples, the folding bracket 100 also includes a locking screw 400. The mounting plate 11 has a mounting hole corresponding to the mounting slot 111, and the locking screw 400 passes through the mounting hole and presses against the raised edge 303 so that the chuck 300 is detachably connected to the mounting plate 11.

[0104] After passing through the mounting hole, the locking screw 400 presses against the raised edge 303, forming a rigid fixation in the axial direction. This prevents the chuck 300 from axially displacing due to the weight of the lamp, vibration, or external forces, ensuring the stability of the connection between the chuck 300 and the mounting plate 11. Furthermore, when the locking screw 400 presses against the raised edge 303, the friction between the contact surfaces of the locking screw 400 and the raised edge 303 can suppress the circumferential rotation of the chuck 300, ensuring that the reflective surface of the diffuser 1000 is always precisely aligned with the optical axis of the lamp, avoiding optical path deviation or deterioration of the diffuser effect due to rotation, and guaranteeing the quality of the light effect.

[0105] For the folding bracket of this application, when the flip panel is rotated to the folded position, the second umbrella rib is arranged on the same side as the first umbrella rib, which allows the umbrella canopy to be folded up. This significantly reduces the overall size of the folding bracket, making it easier for users to carry and move, especially suitable for outdoor shooting, mobile scenarios, or environments with limited space. Furthermore, by unlocking and locking the flip panel through the locking assembly, users can quickly switch the flip panel from the folded position to the open position, allowing the umbrella canopy connected to the first and second umbrella ribs to open rapidly. This effectively shortens preparation time before shooting, improves work efficiency, and enhances the user experience.
