Description

Technical Field

[0001] This application relates to the field of photographic equipment, and in particular to a reverse-support softbox and photographic auxiliary equipment. Background Technology

[0002] When taking photos indoors, a softbox is usually set up to ensure sufficient light.

[0003] Existing umbrella-style softboxes unfold in the same way as ordinary umbrellas, specifically including a support rod 400, reflective cloth 200, frame 100, and light-emitting components. Considering that the objects being photographed have different heights, they are generally used in conjunction with a tripod 500 to adjust the illumination height of the umbrella-style softbox, for example... Figure 1 As shown, the light-emitting component is set on the inner side of the reflective cloth 200. In the unfolded state, one end of the support rod 400 is connected to the frame 100, and the other end extends towards the inner side. When the light-emitting component is working, the umbrella softbox will emit light. However, due to the presence of the support rod 400 and the bracket 500, the light emitted by the umbrella softbox will be blocked by the support rod 400 and the bracket 500, resulting in light shadows on the photographed object or human body and some light loss. Therefore, further improvement is needed. Utility Model Content

[0004] To address the aforementioned problems, this invention provides a reverse-support softbox and photographic auxiliary equipment.

[0005] A reverse-support softbox, with both unfolded and folded states, and a central axis in space, including:

[0006] A foldable frame includes a first rod, a second rod, an upper plate, and a lower plate. The first rod has multiple first rods, each with a fixed end and a free end. The fixed end is hinged to the upper plate. The second rods are arranged in a one-to-one correspondence with the first rods, with one end hinged to the first rod and the other end hinged to the lower plate. The upper plate and the lower plate are located on the center line.

[0007] A flexible reflective cloth, having an inner side and an outer side, is placed on the first rod. In the unfolded state, the reflective cloth is stretched to form a cover-like structure.

[0008] A light-emitting component is disposed on the inner side of the reflective fabric;

[0009] A support rod is arranged along the center line, with one end of the support rod fixedly connected to the lower plate and the other end passing through the upper plate and extending to the outside of the cover-like structure;

[0010] When the reverse-support softbox is unfolded, the upper plate and the lower plate move closer to each other, and the first rod and the second rod rotate away from the center line. When the reverse-support softbox is folded, the upper plate and the lower plate move away from each other, and the first rod and the second rod rotate closer to the center line.

[0011] Several alternative methods are provided below, but they are not intended as additional limitations on the overall solution above. They are merely further additions or optimizations. Provided there are no technical or logical contradictions, each alternative method can be combined individually with respect to the overall solution above, or multiple alternative methods can be combined with each other.

[0020] Optionally, the support rod is arranged horizontally, and the light outlet of the cover-shaped structure is positioned opposite to the bracket.

[0021] This application also provides a reverse-support softbox, which has an unfolded state and a folded state. The reverse-support softbox includes a foldable frame, a flexible reflective cloth, a light-emitting component, and a support rod. The reflective cloth is placed on the frame. In the unfolded state, the reflective cloth is stretched to form a dome-shaped structure. The light-emitting component is disposed in the internal space of the dome-shaped structure. One end of the support rod extends into the dome-shaped structure and connects to the frame, and the other end extends from the top of the dome-shaped structure to its outside. When the reverse-support softbox switches from the unfolded state to the folded state, the dome-shaped structure retracts towards the support rod.

[0022] Optionally, the frame includes an upper plate and a lower plate, one end of the support rod is fixedly connected to the lower plate, and the other end passes through the upper plate and extends to the outside of the cover-like structure.

When a component is said to be "set on" another component, it can be directly set on the other component or it may be set to a component in between.

[0044] 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 application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of the application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

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

[0046] In this application, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, for example, a system, product, or device that includes a series of units is not necessarily limited to those units that are explicitly listed, but may include other units that are not explicitly listed or that are inherent to such products or devices.

[0047] See Figures 2-8 One embodiment of this application provides a reverse-support softbox, which has an unfolded state and a folded state, and has a center line in space. It includes a foldable frame 100, a flexible reflective cloth 200, a light-emitting component 300, and a support rod 400.

[0048] The foldable frame 100 includes a first rod 110, a second rod 120, an upper plate 130, and a lower plate 140. There are multiple first rods 110 arranged radially. The number of first rods 110 can be adapted to meet the requirements. For example, in the figure, there are 8 first rods 110, which are evenly arranged circumferentially.

[0049] Each first member 110 has a fixed end 111 and a free end 112. The fixed end 111 is hinged to the upper plate 130. The second members 120 are arranged in a one-to-one correspondence with the first members 110. For easier understanding of the one-to-one correspondence, please refer to [reference needed]. Figure 3 , Figure 3 The figure shows a frontal projection view of the skeleton 100. In the figure, the second member 120 and the first member 110 coincide on the same straight line. Correspondingly, the number of the second member 120 is also 8.

[0050] Furthermore, one end of the second member 120 is hinged to the first member 110, with the hinge point close to the middle of the first member 110 (of course, the specific position can be adapted according to the needs), and the other end is hinged to the lower plate 140.

[0051] The flexible reflective fabric 200 has an inner side 210 and an outer side 220, and is placed on the first rod 110. In the unfolded state, the reflective fabric 200 is stretched to form a cover-like structure, and the whole is umbrella-shaped. In order to facilitate fixing to the free end 112 of the first rod 110, the edge of the reflective fabric 200 is provided with umbrella buckles 230 that cooperate with and fix to the free end 112.

[0052] The light-emitting component 300 is set on the inner side 210 of the reflective cloth 200. The support rod 400 is arranged along the center line, with one end fixedly connected to the lower plate 140 and the other end passing through the upper plate 130 and extending to the outside of the cover structure. That is, when the light-emitting component 300 is working, the support rod 400 is located on the outer side 220 of the reflective cloth 200, and the light emission will not be blocked, making it easier to use.

[0053] When the reverse-support softbox of this application is unfolded, the upper plate 130 and the lower plate 140 move closer to each other, while the first rod 110 and the second rod 120 rotate away from the center line. When the reverse-support softbox is folded, the upper plate 130 and the lower plate 140 move away from each other, while the first rod 110 and the second rod 120 rotate closer to the center line. That is, when the frame is folded, multiple first rods 110 and second rods 120 can be simultaneously unfolded or retracted, improving the unfolding and retraction speed of the softbox during use.

[0054] See Figures 3-5 The light-emitting component 300 is a light strip 310, including a substrate 311 and LED beads 312 disposed on the substrate 311. Preferably, the substrate 311 is a deformable aluminum substrate so that the light strip 310 can be completely attached to the reflective cloth 200. Of course, the light strip 310 can also be an FPC board (flexible circuit board), which can also be completely attached to the reflective cloth 200. In this embodiment, the substrate 311 is strip-shaped and extends radially. Each substrate 311 is provided with 9 LED beads 312. Considering the issue of more uniform light emission, the LED beads 312 are evenly spaced along the length direction.

[0055] A sector-shaped area is formed between two adjacent first members 110 (e.g. Figure 3 As shown in Figure A), each sector is provided with a light strip 310, and further, each sector is provided with two light strips 310. Preferably, the included angle between the two light strips 310 is 15~35°. In this embodiment, the included angle between the two light strips 310 arranged in each sector is 21°, and the included angle between two adjacent light strips 310 located in different sector areas is 24°.

[0056] For easy lighting, the exterior of the dome structure is equipped with a plug 600 that electrically connects all the light strips 310. That is, when the softbox is needed, simply plug the plug 600 into the power supply to make all the light strips 310 emit light synchronously.

[0057] See Figure 6 The support rod 400 is equipped with a locking member 410 that locks the frame 100 to keep the reverse-support softbox in the unfolded state. For example, in the unfolded state shown in the figure, the locking member 410 can be located outside the cover-like structure and arranged adjacent to the upper plate 130. Of course, the specific structure of the locking member 410 is not particularly required, as long as it can keep the frame 100 in the unfolded state.

[0058] See Figure 2This application also provides a photographic auxiliary device, including a bracket 500 and a reverse-support softbox mounted on the bracket 500. A support rod 400 in the reverse-support softbox is connected to the top of the bracket 500, and the support rod 400 is specifically the support rod 400 described above. When used together, the support rod 400 can be fixed at a suitable length position according to the actual situation.

[0059] In one embodiment, the support rod 400 is arranged horizontally, and the light outlet of the dome structure is set away from the bracket 500. This design avoids the problem of the support rod 400 and the bracket 500 blocking the light when the softbox emits light, and is more convenient for practical use.

[0060] This application also provides other installation methods for the light-emitting component. The light-emitting component 300 is disposed in the internal space of the cover-shaped structure. The internal space is the space defined by the cover opening of the cover-shaped structure. In the aforementioned embodiment, the installation of the light-emitting component 300 on the inner side 210 of the reflective cloth 200 is considered as the light-emitting component 300 being disposed in the internal space of the cover-shaped structure.

[0061] In another embodiment, the light-emitting component 300 is fixed to the frame 100, for example, the light-emitting component 300 is fixed to the first rod 110 or the second rod 120. For example... Figure 9 and Figure 10 As shown, the light-emitting component 300 is arranged between the upper plate 130 and the lower plate 140 and is arranged around the support rod 400. The light-emitting component 300 is a light strip 310 and includes a substrate 311 and LED beads 312 disposed on the substrate 311.

[0062] In one embodiment, there are multiple light strips 310, with adjacent light strips connected together in a circumferential direction, and the connection method includes bonding, binding, etc. Along the axial direction of the support rod 400, at least one end of a light strip 310 is connected to one of the upper plate 130 and the lower plate 140, and the connection method includes bonding, binding, snap-fit, etc. The other end of the light strip 310 is detachably connected to the other plate. In the unfolded state, both ends of the light strip 310 are connected to the upper plate 130 and the lower plate 140 and remain taut. In the folded state, one end of the light strip 310 is separated from the corresponding plate.

[0063] In one embodiment, the radial cross-section of the substrate 311 at the location of the support rod is arc-shaped or straight. Along the axial direction of the support rod 400, the extending direction of the substrate 311 is parallel to or forms a certain angle with the axial direction of the support rod 400.

[0064] In another embodiment, the frame 100 includes a support frame for fixing each light strip 310. The support frame is sleeved on the outer periphery of the support rod 400 and fixedly connected to the upper plate 130 or the lower plate 140. The support frame is a cylindrical structure with a circular or polygonal cross-sectional shape. The support frame extends along the axial direction of the support rod, and its generatrix is ​​parallel to or forms a certain angle with the axial direction of the support rod.

[0065] In one embodiment, the outer edges of the upper plate 130 and the lower plate 140 form an accommodating space, within which the light-emitting component 300 is located, preventing the first rod 110 and the second rod 120 from contacting the light-emitting component 300 and damaging it when it is folded.

[0066] The technical features of the embodiments described above can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered to be within the scope of this specification. When technical features of different embodiments are embodied in the same drawing, it can be regarded as the drawing also disclosing examples of combinations of the various embodiments involved.

[0067] The embodiments described above are merely examples of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these modifications and improvements all fall within the protection scope of this application.
