Description

Technical Field

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

[0002] When taking photos in low-light environments such as indoors or at night, a flash is often needed to supplement the light. Flash can be divided into two categories: built-in flash and external flash. External flash can be further divided into two methods: direct flash on the subject and flash combined with a softbox. Among them, the softbox allows the flash light to spread out according to its shape, making the texture and color of the subject closer to natural light, and is therefore widely favored.

[0003] The diffuser frame is the core component of a softbox, primarily used to mount wire clips and flash units, and to secure the reflector cloth and diffuser cloth using the wire clips. Since softboxes typically need to be disassembled for portability, and traditional diffuser frames often have wire clips wrapped around their outer walls, the overall size of the diffuser frame and wire clips is quite large, making them inconvenient to carry.

[0004] To address this issue, foldable photomask frames have emerged on the market. For example, document CN209297081U discloses a foldable photomask frame, including multiple support rods, a base, and fixing components. The multiple support rods include multiple first support rods and multiple second support rods; the base includes a ring-shaped seat and an installation space defined by the seat for mounting light-emitting devices; the fixing components include a first fixing component and a second fixing component, the first fixing component being disposed on the upper surface of the seat, and the second fixing component being opposite to the first fixing component and foldable.

[0005] However, although this type of folding light cover holder has a folding function, it has obvious shortcomings. When the second fixing member is folded around the first fixing member, the two will interfere with each other and form an angle, making it impossible to stack them completely. As a result, the overall volume is still large, and the convenience of storage has not been fully improved. Utility Model Content

[0006] To address the aforementioned problems, this utility model provides a softbox chuck, a softbox support frame, and a softbox.

[0007] A softbox chuck has a ring-shaped structure. The softbox chuck includes a fixed base, a movable base, and a connector connecting the fixed base and the movable base. The connector is rotatably connected to the fixed base and the movable base via a first pivot and a second pivot that are not collinear, respectively. The movable base can be flipped relative to the fixed base via the connector and has an unfolded position and a folded position. The fixed base includes a first mounting portion and a second mounting portion arranged circumferentially thereon. In the unfolded position, the movable base engages with the first mounting portion. In the folded position, the movable base is stacked on the fixed base.

[0008] 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.

[0009] Optionally, in the folded position, the movable seat is stacked on the second mounting portion.

[0010] Optionally, the fixed base has a notch adapted to the movable base, and in the unfolded position, the surface of the movable base is flush with the surface of the fixed base.

[0011] Optionally, a locking device is provided between the movable seat and the first mounting part.

[0012] Optionally, the movable seat has an arc-shaped structure, with both ends adjacent to the second mounting part, and each end is rotatably connected to the second mounting part through a connector.

[0013] Optionally, the end of the movable seat and the second mounting part are respectively provided with a first mounting groove and a second mounting groove, and the connector is housed in the storage space formed by the first mounting groove and the second mounting groove.

[0014] Optionally, a first positioning structure is provided between the movable seat and the first mounting part, and a second positioning structure is provided between the movable seat and the second mounting part.

[0015] Optionally, the first positioning structure includes a first positioning protrusion disposed on one of the movable seat and the first mounting portion, and a first positioning groove disposed on the other; the second positioning structure includes a second positioning protrusion disposed on one of the movable seat and the second mounting portion, and a second positioning groove disposed on the other.

[0016] Optionally, in the unfolded position, the movable seat and the first mounting part are respectively located on opposite outer and inner sides in the radial direction.

[0017] Optionally, the first pivot and the second pivot are parallel to each other.

[0018] This application also discloses a support frame for a softbox, characterized in that it includes a softbox chuck as described above, and a plurality of support rods arranged radially around the chuck. The support rods are divided into a first group of support rods and a second group of support rods. The first group of support rods is installed on the movable seat, and the second group of support rods is installed on the second mounting part of the fixed seat.

[0019] Optionally, the softbox chuck is provided with mounting holes for mounting the support rod, and at least some of the mounting holes are fan-shaped to allow the corresponding support rod to swing laterally and retract.

[0020] This application also discloses a softbox, characterized in that it includes a support frame as described above, and a softbox fabric connected to the support rod; in the unfolded state, the support frame expands the softbox fabric to form a dome-shaped structure.

[0021] The softbox chuck of this application is rotatably connected to the fixed base and the movable base via a non-collinear first pivot and a second pivot, respectively. When the movable base rotates, it first rotates relative to the connector around the first pivot, and then drives the connector to rotate around the second pivot towards the fixed base. Compared with the existing single-pivot technology, the non-collinear double-pivot structure can provide rotational clearance, which can effectively avoid interference between the movable base and the fixed base, and thus allow the two to be stacked parallel and close together, greatly reducing the storage volume.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0025] It should be noted that when a component is said to be "connected" to another component, it can be directly connected to the other component or it can be connected to a component in between. 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.

[0026] 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.

[0027] 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.

[0028] 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.

[0029] See Figures 1-10 One embodiment of this application provides a softbox chuck 10, including a fixed base 100, a movable base 200, and a connector 300 connecting the fixed base 100 and the movable base 200.

[0030] The softbox chuck 10 has a ring-shaped structure, with its center defining an installation space for mounting lighting devices. In other words, the installation space is located in the middle of the ring structure, where the light-emitting device is installed to emit uniform light through reflection. Common light-emitting devices include flashlights, LED lamp heads, etc.

[0031] The fixed base 100 and the movable base 200 are relative, meaning that one can be flipped and moved relative to the other. In this embodiment, the fixed base 100 includes a first mounting portion 110 and a second mounting portion 120 arranged circumferentially thereon. The movable base 200 is flipped relative to the fixed base 100 via a connector 300 and has an unfolded position and a folded position. In the unfolded position, the movable base 200 engages with the first mounting portion 110; in the folded position, the movable base 200 stacks on top of the fixed base 100 to reduce the overall storage space.

[0032] The unfolded position is the usage state of the softbox chuck 10 after it can be fixed with the light-emitting device; the folded position is the storage state of the softbox chuck 10. For easier understanding, please refer to [link to relevant documentation]. Figure 1 and Figure 9 , Figure 1 For the corresponding expansion position, Figure 9 This indicates the corresponding folding position.

[0033] In one embodiment, the fixed base 100 is provided with a notch 130 for adapting to the movable base 200. The notch 130 provides a precise installation and positioning space for the movable base 200, preventing the movable base 200 from shifting or wobbling due to size mismatch, and ensuring the stability of the structural assembly. In the unfolded position, the surfaces of the movable base 200 and the fixed base 100 are flush, meaning that the overall structure of the softbox chuck 10 is flat after unfolding, and local protrusions will not affect light reflection, thus preventing uneven light emission.

[0034] In one embodiment, see Figures 1-3The notch 130 is located on the outer side of the first mounting part 110. In the unfolded position, the movable seat 200 and the first mounting part 110 are located on opposite outer and inner sides in the radial direction, respectively. At this time, the surfaces of the movable seat 200 and the fixed seat 100 are flush, forming a complete ring structure, which is more aesthetically pleasing overall.

[0035] To ensure that the movable base 200 and the first mounting part 110 remain fixed in the unfolded position and to prevent the movable base 200 from rotating accidentally, a locking device is provided between the movable base 200 and the first mounting part 110.

[0036] Regarding the structure of the locking device, for example, a positioning hole 240 may be provided on one of the movable base 200 and the first mounting portion 110, and a movable locking tongue 113 that can be adapted to the positioning hole 240 may be provided on the other. Figures 2-4 Taking the structure as an example, the movable seat 200 is provided with positioning holes 240, and the first mounting part 110 has a receiving cavity 112, in which the locking tongue 113 is movably assembled. To facilitate unlocking, a sliding groove 114 is provided on the side wall of the receiving cavity 112, and a driving member 115 that can slide along the sliding groove 114 is also provided on the outer side of the receiving cavity 112. The driving member 115 passes through the sliding groove 114 and is fixedly connected to the locking tongue 113. Meanwhile, an elastic member 116 is installed at the bottom of the locking tongue 113 (see...). Figure 4 ), used to ensure that it remains locked with the positioning hole 240 in its natural state.

[0037] In its natural state, under the elastic force of the elastic element 116, the drive element 115 abuts against the end of the slide groove 114. At this time, the locking tongue 113 partially exposes the receiving cavity 112, which can precisely lock with the positioning hole 240 of the movable seat 200. When unlocking is required, the drive element 115 is moved along the slide groove 114, causing the locking tongue 113 to move away from the positioning hole 240, thus completing the unlocking operation. To facilitate locking, the portion of the locking tongue 113 exposed in the receiving cavity 112 is provided with a guide slope 117, so that the movable seat 200 can automatically lock after being flipped into place.

[0038] In one embodiment, the locking device is positioned between the movable seat 200 and the first mounting portion 110. This central arrangement avoids localized force concentration caused by the offset of the locking point, ensuring that the movable seat 200 and the first mounting portion 110 can uniformly transmit external forces (such as the tension of the soft fabric) through the locking device when in the unfolded state, thereby reducing the risk of structural deformation.

[0039] In one embodiment, a handle 140 may also be provided on the fixing base 100, see [reference]. Figure 10The handle 140 is fixed to the first mounting part 110, and a groove 114 is provided on the handle 140. The driving member 115 passes through the handle 140 and is fixedly connected to the locking tongue 113. In the unfolded position, the handle 140 protrudes radially outward relative to the movable seat 200. The handle 140 provides a force point. When unfolded, the handle 140 and the movable seat 200 can be squeezed to bring them closer together, thereby locking the movable seat 200.

[0040] In one embodiment, the connector 300 is rotatably connected to the fixed base 100 and the movable base 200 via a non-collinear first pivot L1 and a second pivot L2, respectively. In the figure, the movable base 200 is rotatably connected to the connector 300 via the first pivot L1, and the fixed base 100 is rotatably connected to the connector 300 via the second pivot L2. When the movable base 200 is manually moved outward, it first rotates relative to the connector 300 around the first pivot L1. Then, the movable base 200 drives the connector 300 to flip around the second pivot L2 toward the fixed base 100, so that in the folded position, the movable base 200 is stacked on top of the fixed base 100.

[0041] In the softbox chuck 10 of this application, the movable seat 200 and the fixed seat 100 are rotatably connected by non-collinear double pivots. The purpose of this non-collinearity is to provide a rotational clearance for the relative movement of the movable seat 200 and the fixed seat, thereby effectively avoiding interference between the two during folding and ensuring that the two can be parallel and close together when stacked, thus greatly reducing the storage volume.

[0042] In one embodiment, the movable seat 200 has a semi-circular structure, and the corresponding second mounting part 120 also has a semi-circular structure. In the folded position, the movable seat 200 is stacked on the second mounting part 120, and the surfaces of the two are completely in contact, making the folded structure more compact and reducing the space occupied by the movable seat 200 and other areas of the fixed seat 100.

[0043] In one embodiment, the first pivot L1 and the second pivot L2 are parallel to each other. The parallel dual pivots ensure that the movable seat 200 always moves along a preset parallel trajectory when it flips, avoiding flipping jams or positional shifts of the movable seat 200 due to pivot angle deviations, and further improving the stability and smoothness of state switching.

[0044] In one embodiment, the movable seat 200 has an arc-shaped structure, and can be further selected as a semi-circular structure. Both ends of the movable seat 200 are adjacent to the second mounting part 120, and each end is rotatably connected to the second mounting part 120 through a connector 300. The arc-shaped structure can accurately fit the overall annular contour of the chuck, avoiding spatial interference. At the same time, through the structural design of the double connectors 300 and the support at both ends, the force on the movable seat 200 when it is flipped is distributed, ensuring that the rotation process of the movable seat 200 is more stable and smooth when switching between the unfolded and folded positions, and will not affect the use due to uneven force.

[0045] For the specific installation location of connector 300, please refer to [link / reference]. Figures 2-5 The end of the movable seat 200 and the second mounting part 120 are respectively provided with a first mounting groove 210 and a second mounting groove 121. The connector 300 is housed in the storage space formed by the first mounting groove 210 and the second mounting groove 121, which effectively avoids the components from being exposed and makes the structure neater.

[0046] In terms of rotational engagement, the first mounting groove 210 can rotate relative to the connector 300 along the first pivot L1, and the second mounting groove 121 can rotate relative to the connector 300 along the second pivot L2. In one embodiment, when the first mounting groove 210 rotates relative to the connector 300 along the first pivot L1, it is also provided with a preset rotation limit position. When the first mounting groove 210 rotates to this limit position, it will further drive the connector 300 to continue moving along the second pivot L2 toward the second mounting part 120, thereby realizing the orderly flipping of the dual-axis linkage.

[0047] In order to enable the movable seat 200 to quickly and accurately align with the first mounting part 110 when flipped to the unfolded position, so as to find the correct engagement position without repeated adjustments, and at the same time to ensure the smooth operation of the locking device and the structural stability after unfolding, a first positioning structure is provided between the movable seat 200 and the first mounting part 110, and a second positioning structure is provided between the movable seat 200 and the second mounting part 120.

[0048] Regarding the first positioning structure, the first positioning structure includes a first positioning protrusion 220 disposed on one of the movable seat 200 and the first mounting portion 110, and a first positioning groove 111 disposed on the other. For example, see [reference needed]. Figure 2 and Figure 6 The first positioning protrusion 220 is disposed on the movable seat 200, and the first positioning groove 111 is disposed on the first mounting part 110.

[0049] The first positioning protrusion 220 protrudes radially relative to the inner surface of the movable seat 200, and the first positioning groove 111 is correspondingly arranged on the outer surface of the first mounting part 110, and the first positioning groove 111 extends to the upper surface of the first mounting part 110, so that the first positioning protrusion 220 can enter the first positioning groove 111 from the upper surface of the first mounting part 110.

[0050] Regarding the second positioning structure, the second positioning structure includes a second positioning protrusion 230 disposed on one of the movable seat 200 and the second mounting portion 120, and a second positioning groove 122 disposed on the other. For example, see [reference needed]. Figure 2 and Figure 7 The second positioning protrusion 230 is disposed on the movable seat 200, and the first positioning groove 111 is disposed on the second mounting part 120.

[0051] The second positioning protrusion 230 protrudes radially relative to the end of the movable seat 200, and the second positioning groove 122 is arranged on the lower surface of the second mounting part 120, so that the second positioning protrusion 230 can enter the second positioning groove 122 from the lower surface of the first mounting part 110.

[0052] The cooperation between the first positioning protrusion 220 and the first positioning groove 111, and the second positioning protrusion 230 and the second positioning groove 122, can form a double constraint on the movable seat 200 in the unfolded position from different directions. This not only ensures the accuracy of the alignment between the movable seat 200 and the fixed seat 100, but also enhances the structural stability in the unfolded state. At the same time, it can simplify operation and improve ease of use.

[0053] When the movable seat 200 of this application is switched from the unfolded position to the folded position, see [reference needed]. Figure 1 , Figure 5 , Figure 8 and Figure 9 First, the drive member 115 can be turned to disengage the locking tongue 113 from the positioning hole 240 to unlock it. Then, a force is applied to the movable seat 200 toward the second mounting part 120 (in the figure, the force is clockwise). The movable seat 200 rotates relative to the connector 300 along the first pivot L1. The second positioning protrusion 230 gradually disengages from the second positioning groove 122 until it rotates to the limit position. Then, the movable seat 200 drives the connector 300 to continue moving along the second pivot L2 toward the second mounting part 120. The first positioning protrusion 220 gradually disengages from the first positioning groove 111 until the movable seat 200 is stacked on the second mounting part 120 and the surfaces of the two are in contact, thus completing the folding.

[0054] When switching from the folded position to the unfolded position, a force can be applied to the movable seat 200 toward the first mounting part 110. After the movable seat 200 rotates to its limit position relative to the connector 300 along the first pivot L1, the movable seat 200 drives the connector 300 to continue moving toward the first mounting part 110 along the second pivot L2 until the first positioning protrusion 220 and the first positioning groove 111, and the second positioning protrusion 230 and the second positioning groove 122 cooperate with each other, and the locking tongue 113 enters the positioning hole 240, thus completing the locking.

[0055] In one embodiment, this application also discloses a support frame for a softbox, including a softbox chuck 10 as described above, and multiple support rods 20 arranged radially around the chuck. The support rods 20 are divided into a first group of support rods 21 and a second group of support rods 22. The first group of support rods 21 is mounted on a movable base 200, and the second group of support rods 22 is mounted on a second mounting portion 120 of a fixed base 100. Preferably, the number of the first support rods and the number of the second support rods are the same, and the spacing between adjacent support rods is approximately the same.

[0056] When the movable seat 200 flips relative to the fixed seat 100, the first set of support rods 21 flips simultaneously. The first set of support rods 21 and the second set of support rods 22 in the folded position are in a one-to-one correspondence, which makes it easy to fold and carry.

[0057] In one embodiment, the softbox chuck 10 is provided with mounting holes 400 for mounting support rods. At least some of the mounting holes 400 are fan-shaped to allow the corresponding support rods to swing laterally. This provides the softbox (or related components connected to the support rods) with the possibility of angle adjustment, which can meet the lighting direction and position requirements in different scenarios, and improve the flexibility and applicability of the equipment.

[0058] This application also discloses a softbox, see [link to relevant documentation] Figure 11 This includes the support frame of the softbox mentioned above, and the soft cloth 30 connected to the support rod 20. In the unfolded state, the support frame expands the soft cloth 30 to form a dome-shaped structure.

[0059] 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.

[0060] 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.
