[0038] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0039] It should be noted that when a component is referred to as being "connected" to another component, it may be directly connected to the other component or there may be a central component. When a component is referred to as being "disposed on" another component, it may be directly disposed on the other component or there may be a central component at the same time.

[0040] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those generally understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0041] like Figures 1 to 5 As shown, the present application provides a foldable photographic light reflective device 100, including a chuck 10, a plurality of support rods 20 radially distributed with the chuck 10 as the center, and a reflective cloth 40 lining the support rods 20, one end of the support rod 20 is hinged to the chuck 10, and has an unfolded state and a folded state for supporting the reflective cloth 40 to form a cover structure.

[0042] The chuck 10 is mounted on the lamp head of the photography lamp, and a through hole 14 corresponding to the lamp head is provided at the center of the chuck 10, and the size of the through hole 14 is set according to the specific requirements of the lamp head. The expansion and folding of each support rod 20 can correspondingly drive the expansion and folding of the reflective cloth 40, and the number of support rods 20 is selected according to actual requirements, so that the reflective device 100 has different shapes (such as square, octagonal, etc.).

[0043] The support rod 20 can be inserted inside or outside the reflective cloth 40. The so-called inside means that the support rod 20 is located on the inner side of the cover structure, and the so-called outside means that the support rod 20 is located on the outer side of the cover structure. Generally, it is fixed by inserting into a radially arranged sleeve on the reflective cloth 40.

[0044] The reflective device 100 may be a soft box or a radome. A soft cloth is generally provided at the mouth of the cover of the soft box, and is often connected to the inner wall of the cover by Velcro.

[0045] In order to keep the support rod 20 in the unfolded state, a locking mechanism 30 is provided between the support rod 20 and the chuck 10. Specifically, the locking mechanism 30 includes a swinging member 31 and a retaining member (not shown in the figure), the middle part of the swinging member 31 is hinged to the chuck 10, and is divided into an operating portion 311 and a matching portion 312 at the hinge, and the matching portion 312 of the swinging member 31 has two states of locking and releasing the support rod 20; the retaining member is used to limit the swinging member 31 to the locked state.

[0046] When the swing member 31 is in the locked state, the holder restricts the swing member 31 in the locked state, and the reflective device 100 is in the deployed state; the swing member 31 overcomes the resistance of the holder and is in the released state, and by rotating the support rods 20, all the support rods 20 are folded to put the reflective device 100 in the folded state. When the support rods 20 are turned from the deployed state to the folded state, the operating part 311 of the swing member 31 drives the matching part 312 to move until the matching part 312 switches to the released state, and the support rods 20 can be folded, that is, the support rods 20 can rotate around the chuck 10 to change the relative position with the chuck 10.

[0047] In the present application, the locking mechanism 30 has a simple structure, which can reduce the difficulty of assembling the components, extend the service life of the locking mechanism 30, and make the operation more convenient.

[0048] In some embodiments, the retaining member is a torsion spring, which is sleeved on the rotating pivot of the swing member 31 and acts between the swing member 31 and the chuck 10. Of course, in other embodiments, the retaining member can also be a compression spring or other reset member, as long as the retaining member can drive the matching portion 312 of the swing member 31 and the support rod 20 to be in a locked state.

[0049] In some embodiments, Figure 1 and Figure 5 As shown, the support rod 20 has a hinged end 21 and a free end 22, and the edge of the chuck 10 is provided with a mounting groove 15 that matches the hinged end 21 of the support rod 20 to prevent the hinged end 21 of the support rod 20 from being exposed and only allows the support rod 20 to rotate in a single direction, so the mounting groove 15 is open on one side.

[0050] The specific configuration of the support rod 20 is shown in one embodiment. Figure 5 and Figure 6As shown, the support rod 20 includes a connection seat 23 hinged to the chuck 10 and a rod body 24, one end of the rod body 24 is plugged into the connection seat 23, and the other end extends away from the chuck 10. In some embodiments, the rod body 24 is made of metal and has a certain elasticity.

[0051] Regarding the connection method between the rod body 24 and the connection seat 23, referring to one embodiment, the rod body 24 and the connection seat 23 are detachably plugged in. Specifically, the connection seat 23 has a plug hole 231, and the rod body 24 can be plugged into the plug hole 231. In order to fix the rod body 24 in the plug hole 231, in some embodiments, the rod body 24 and the plug hole 231 are interference fit. Of course, in other embodiments, a rivet is provided between the rod body 24 and the connection seat 23, and the rivet fixes the rod body 24 in the plug hole 231.

[0052] In this embodiment, Figure 2 and Figure 3 As shown, the mating portion 312 of the swing member 31 extends into the mounting groove 15 to lock the support rod 20, so as to prevent the mating position of the mating portion 312 of the swing member 31 and the support rod 20 from being exposed to the outside; at the same time, the operating portion 311 protrudes from the chuck 10 to facilitate the operator to operate the operating portion 311.

[0053] The operating portion 311 of the swinging member 31 extends obliquely along the radial direction of the chuck toward its geometric center, so that the operating portion and the matching portion 312 form an angle. When the reflective device needs to be folded, by pressing the operating portion 311, the matching portion 312 will be lifted upward, thereby achieving unlocking. The operating portion 311 is also provided with anti-slip grooves, which can increase the friction of the operator's hand.

[0054] In some embodiments, in order to enhance the strength of the swing member 31 and reduce the difficulty of processing the swing member 31, the swing member 31 is provided in one piece. Of course, in other embodiments, the swing member 31 may also be provided in separate pieces.

[0055] In order to ensure that the structure of the swing member 31 and the support rod 20 is stable when locked, in this embodiment, Figure 4 and Figure 7 As shown, the matching portion 312 of the swinging member 31 has an opening slot 317 for avoiding the support rod 20 , thereby forming two locking arms 315 for locking the support rod 20 . The two locking arms 315 are located at two opposite sides of the connecting seat 23 .

[0056] In order to enable the locking arm 315 to stably move in the installation slot 15, referring to one embodiment, the locking arm 315 is clearance-matched with the side wall of the installation slot 15 and the side of the support rod 20. Of course, in order to make the locking arm 315 and the connecting seat 23 cooperate more stably, in other embodiments, the locking arm 315 is fitted with the corresponding side of the connecting seat 23 and is clearance-matched with the corresponding groove wall of the installation slot 15. Furthermore, the two opposite sides of the connecting seat 23 have matching planes, and each locking arm 315 is fitted with the corresponding matching plane, so that the locking arm 315 and the connecting seat 23 are in surface contact.

[0057] In this embodiment, Figure 4 and Figure 6 to Figure 7 As shown, the support rod 20 has a locking block 25 protruding from its side, and the locking arm 315 is bent inward to form a locking hook 316 that matches the locking block 25. Specifically, the line between the contact point between the locking hook 316 and the locking block 25 and the hinge point of the support rod 20 is perpendicular to the hinge end 21 of the support rod 20, so as to avoid the locking mechanism 30 being locked by mistake when the support rod 20 is rotated.

[0058] In some embodiments, the locking block 25 and the locking hook 316 are respectively provided with a first locking surface 251 and a second locking surface 318 that abut against each other in the locked state, and a first arc transition surface 252 and a second arc transition surface 319 that respectively connect the first locking surface 251 and the second locking surface. When the reflective device 100 needs to be opened, the support rod 20 needs to be rotated in the reverse direction, and firstly the two arc transition surfaces abut against each other, and the matching portion 312 of the swing member 31 can be pushed up until it moves to the two locking surfaces, and the locking can be automatically achieved without manual operation of the swing member 31.

[0059] The specific configuration of the chuck 10 is described with reference to one embodiment. Figure 8 As shown, the chuck 10 includes a body 11 and a cover 12, a mounting groove 15 is provided at the edge of the body 11, and is open on both sides, and the cover 12 is used to close one side opening of the mounting groove 15 to interfere with the running path of the support rod 20. The swing member 31 is hinged to the cover 12.

[0060] Specifically, the chuck 10 is annular and has an axial direction and a radial direction perpendicular to the axial direction. The body 11 and the cover 12 are both annular. The cover 12 and the body 11 are attached to and fixed to each other along the axial direction of the chuck 10 .

[0061] In some embodiments, Figure 4As shown, the connecting seat 23 is provided with a first rotating shaft 26, and the first rotating shaft 26 and the connecting seat 23 are integrally or separately arranged; the swing member 31 is provided with a second rotating shaft 32, and the second rotating shaft 32 and the swing member 31 are integrally or separately arranged; the cover body 12 and the main body 11 are engaged with each other to form a first rotating groove 16 that matches the first rotating shaft 26, and a second rotating groove 17 that matches the second rotating shaft 32.

[0062] When assembling the reflective device 100, first pre-assemble the connecting seat 23 and the swinging member 31 at predetermined positions of the main body 11, and then restrict the first rotating shaft 26 and the second rotating shaft 32 in the corresponding first rotating groove 16 and the second rotating groove 17 through the cover body 12 to facilitate the assembly of the above components.

[0063] According to the needs of the photographic light, in some embodiments, such as Figure 2 and Figure 8 As shown, the reflective device 100 further includes a Bowens bayonet mount 50 , and the reflective device 100 is connected to the photographic light via the Bowens bayonet mount 50 .

[0064] In order to facilitate the installation of the Bowent mount 50 and the chuck 10, referring to one embodiment, the chuck 10 has a positioning step 13, and the outer edge of the Bowent mount 50 is placed on the positioning step 13, so that the installation positions of the Bowent mount 50 and the chuck 10 can be quickly located. Among them, the inner diameter of the body 11 is smaller than the inner diameter of the cover 12, so that the positioning step 13 is formed between the cover 12 and the body 11.

[0065] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification. When the technical features in different embodiments are embodied in the same figure, it can be regarded that the figure also discloses the combination examples of the various embodiments involved.

[0066] The above embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
