Description

Technical Field

[0001] The utility model relates to the technical field of video booths, in particular to a video booth. Background Art

[0002] Video booths are often used in various occasions such as education and teaching training, video conferences, and seminars. They are a kind of demonstration equipment used to convert physical objects, documents, pictures and other information into image signals and display the image signals on display devices such as cameras and monitors.

[0003] In the related art, a video booth usually includes a base and a camera assembly mounted on the base, with the camera assembly being positioned toward a target shooting area. In order to supplement the light for the target shooting area, a fill light is usually provided. The fill light is generally located at a relatively upper portion of the base, so that the light from the fill light illuminates the target shooting area from top to bottom. However, the light is emitted outward in a divergent manner with the light source as the center. That is, the brightness of points at different distances from the optical axis is different. In other words, in the traditional fill light form, when the fill light illuminates the shooting area from above to below, the light propagates over a longer distance, so the divergence of the fill light is more obvious. The shooting area is usually a plane, so the light in the area away from the optical axis of the fill light will become weaker, while the light intensity in the area close to the optical axis of the fill light will be higher. This can easily lead to the central area being relatively brighter and the surrounding area being relatively darker during shooting. When the environment is very dark, the brightness difference between the central area and the surrounding area will be even greater during shooting, affecting the viewing experience. Utility Model Content

[0004] The embodiment of the present application provides a video display stand, which can reduce the difference in brightness and darkness of the picture during shooting and improve the shooting effect.

[0005] An embodiment of the present application provides a video booth, comprising a booth body and a support plate assembly, wherein the booth body comprises a housing and a camera assembly mounted on the housing; the support plate assembly is rotatably connected to the housing and can be expanded or retracted relative to the housing; the support plate assembly comprises an outer shell and a first light source arranged in the outer shell, wherein the outer shell is rotatably connected to the housing and can be expanded or retracted relative to the housing; the outer shell comprises a bearing surface and a light-transmitting portion located on the bearing surface; wherein the camera assembly is used to photograph an object to be photographed placed on the bearing surface, and the light-transmitting portion is used to evenly distribute light emitted by the first light source on the bearing surface and illuminate the object to be photographed.

[0006] In the video display stand according to the embodiment of the present application, the first light source is located below the support surface. Light emitted by the first light source shines upward from the bottom, passing through the support surface and illuminating the object to be photographed. The light passing through the object to be photographed provides fill lighting for the object. The object to be photographed can be a light-transmitting material such as paper or plastic. Because the first light source provides fill lighting to the object from the bottom, the light emitted by the first light source has a shorter travel distance to the object to be photographed, minimizing significant variations in brightness and darkness during the capture.

[0007] In one possible implementation, the housing includes an upper shell and a lower shell, the upper shell and the lower shell enclose an installation cavity, and the first light source is installed in the installation cavity; wherein, the upper shell is made of a light-transmitting material and has the bearing surface and is formed as a light-transmitting portion, and the lower shell is a non-light-transmitting setting.

[0008] In this implementation, only the area where the object needs to be photographed can be set as the light-transmitting part, and the other areas can be set as the non-light-transmitting part. In this way, the light can be prevented from scattering everywhere during use, causing a glare and bad experience for the user. The upper shell is set as the light-transmitting part, so the processing technology is simple and can meet the requirement of reducing glare to a certain extent.

[0009] In a possible implementation, the upper shell includes a light-transmitting substrate and a light-distributing structure embedded in the light-transmitting substrate.

[0010] In this implementation, the light-evening structure can make the light presented softer and more uniform, and the light-evening powder can also make the light-transmitting part have a certain color, similar to milky white, which can form a certain shielding effect, and the user cannot see the specific structure inside the shell, which has better aesthetics.

[0011] In a possible implementation, the upper shell includes a light-transmitting substrate, and the light-transmitting substrate is formed with a light-evening convex portion or a light-evening concave portion.

[0012] In this implementation, the light emitted by the first light source is evenly distributed and diffused by the light-homogenizing convex portion, thereby reducing light spots and shadow effects.

[0013] In a possible implementation, the light source is an LED light film.

[0014] In this implementation, the first light source is generally of a flat structure and can be easily installed in the installation cavity. It can also emit relatively uniform light below the bearing surface, thereby improving the fill light effect.

[0015] In a possible implementation, a second light source is further included, which is installed on the housing and is used to illuminate the object to be photographed placed on the supporting surface from top to bottom for fill light.

[0016] In one possible implementation, the housing includes a main body and a protrusion fixed together, the protrusion is protruding from one side of the main body, the support plate assembly is connected to the main body, and the support plate assembly and the protrusion are located on the same side of the main body and are spaced apart in the upper and lower directions of the main body; the camera assembly and the second light source are both installed on the protrusion.

[0017] One possible implementation further includes a rotating shaft and a damping structure, where the rotating shaft includes a first shaft segment and a second shaft segment, the housing is fixedly connected to the first shaft segment, and the support plate assembly is rotatably mounted on the second shaft segment; the damping structure connects the second shaft segment and the support plate assembly, and is used to provide damping force during the rotation of the support plate assembly relative to the booth body.

[0018] In this implementation, the support plate assembly has better stability in the folded state.

[0019] One possible implementation further includes a rotating shaft and a damping structure, where the rotating shaft includes a first shaft segment and a second shaft segment, the support plate assembly is fixedly connected to the first shaft segment, and the casing is rotatably mounted on the second shaft segment; the damping structure connects the second shaft segment and the casing, and is used to provide damping force during the rotation of the support plate assembly relative to the booth body.

[0020] In one possible implementation, the damping structure includes an elastic member and a friction member, wherein the elastic member is slidably arranged in the axial direction of the second shaft segment and is fixed relative to the second shaft segment in the circumferential direction of the second shaft segment;

[0021] The friction member is fixedly connected to the casing and can be rotatably arranged relative to the second shaft section.

[0022] In a possible implementation, when the support plate assembly is in the folded state, the bearing surface is arranged at an angle to the vertical direction and is tilted in a direction close to the housing.

[0023] In this implementation, the support plate assembly has higher stability when folded, preventing the support plate assembly from expanding outward in the folded state. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] Video booths are often used in various occasions such as education and teaching training, video conferences, and seminars. They are a kind of demonstration equipment used to convert physical objects, documents, pictures and other information into image signals, and display the image signals on display devices such as smart screens and projectors.

[0044] The video booth has two forms: with a video arm and without a video arm. In the structure without a video arm, the video booth usually includes a base, a fill light and a camera assembly provided on the base. Specifically, a camera channel facing downward is provided on the base, and the camera assembly is installed in the camera channel. The shooting light of the camera assembly is tilted toward the target area below the base through the camera channel for shooting. At the same time, the fill light is tilted so that the light emitted by the fill light is tilted toward the target area. However, the light is emitted outward in a divergent form with the fill light as the center. That is to say, the brightness of points at different distances from the optical axis is different. That is to say, when the fill light shines from above to the shooting area below, the light propagates a longer distance, so the divergence of the fill light is more obvious, which can easily lead to a picture with one side bright and the other side dark during shooting, affecting the viewing experience.

[0045] A video display stand with a video arm is based on an armless display stand, but with an additional arm rotatably connected to the base. The fill light is mounted on the arm. This arrangement allows the arm to move the fill light when deployed. However, due to the characteristics of light emission, the center of the image is closer to the optical axis, while the periphery of the image is farther away from the optical axis. As a result, the image captured by the camera assembly will still be bright in the center and dark around the edges, affecting the viewing experience. In very dark environments, the difference in brightness is even greater, seriously affecting the viewing experience.

[0046] The embodiment of the present application proposes a video booth 1, which provides a new fill light method, which can solve the problem of large differences in brightness and darkness of the picture during shooting caused by traditional fill light solutions, thereby improving the shooting effect. Figure 1 In the embodiment of the present application, the video booth 1 includes a booth body 10 and a support plate assembly 20 .

[0047] The exhibition stand 10 includes a housing 110 and a camera assembly 130. The camera assembly 130 is mounted on the housing 110 and is used to capture images of objects and transmit the captured images to an external device. The external device may be an LCD screen, an LED screen, a projector, or other device.

[0048] The tray assembly 20 is rotatably connected to the housing 110 and can be switched between an extended state and a collapsed state relative to the housing 110. It will be appreciated that the video display stand 1 includes a rotating shaft 50, through which the tray assembly 20 and the housing 110 are rotatably connected. To facilitate placement of the video display stand 1 on a desktop for use, in some connection configurations, the tray assembly 20 is rotatably connected to the bottom of the housing 110. Of course, in other embodiments, the tray assembly 20 can be rotatably connected to the middle and lower portion of the housing 110, and this application is not limited thereto.

[0049] Please refer to Figure 2 The support plate assembly 20 includes a housing 21 and a first light source 25 disposed within the housing 21. The housing 21 is rotatably connected to the housing 110 via a rotating shaft 50. The housing 21 includes a supporting surface 24 and a light-transmitting portion located on the supporting surface 24. The camera assembly 130 is used to photograph an object placed on the supporting surface 24. The light-transmitting portion is used to evenly distribute the light emitted by the first light source 25 onto the supporting surface 24 and illuminate the object to be photographed, thereby providing fill light for the object.

[0050] In the present application, the first light source 25 is located at the lower portion of the supporting surface 24. The light emitted by the first light source 25 irradiates from bottom to top, passes through the light-transmitting portion and illuminates the object to be photographed. The light passes through the object to be photographed, thereby supplementing the illumination of the object to be photographed. The object to be photographed can be a light-transmitting component such as paper or plastic paper. Because the first light source 25 supplements the illumination of the object to be photographed from the bottom of the object to be photographed, the distance traveled by the light emitted by the first light source 25 to the object to be photographed is short, and the divergence of the light is limited. In this way, there will not be a large difference in the brightness and darkness of the picture when shooting. In addition, the light-transmitting portion evenly distributes the light emitted by the first light source 25, thereby making the light irradiated on the object to be photographed more uniform.

[0051] Furthermore, the first light source 25 can be configured as a surface light source, which can include an LED array. This surface light source can provide very uniform lighting, avoiding obvious light spots and shadows. The surface light source is laid out as a whole below the supporting surface 24. That is, when the first light source 25 of the present application emits fill light, it is configured to cover the entire supporting surface 24. This can further reduce the difference in light brightness during shooting.

[0052] Please refer again Figure 2In one embodiment, the housing 21 includes an upper shell 22 and a lower shell 23, and the upper shell 22 and the lower shell 23 enclose an installation cavity, in which the first light source 25 is installed; the upper shell 22 is made of a light-transmitting material and is formed as a light-transmitting portion, and the lower shell 23 is a non-light-transmitting setting. Among them, the upper shell 22 can be injection-molded using materials such as PC and PMMA, and the lower shell 23 can also be injection-molded using a light-transmitting material, and then a non-light-transmitting film layer is coated or attached to the inner surface or outer surface of the lower shell 23, such as spraying or rolling non-light-transmitting ink on the inner surface or outer surface of the lower shell 23; a non-light-transmitting metal or compound film can also be formed on the surface by chemical deposition or physical deposition. The present application does not limit the specific materials of the upper shell 22 and the lower shell 23. In the present application, the upper shell 22 is set as the light-transmitting portion, which is simple to process and can meet the requirements of reducing glare to a certain extent. Of course, in some other embodiments, a non-light-transmitting area may be provided on the upper shell 22, with only the area of ​​the bearing surface 24 facing downward being provided as a light-transmitting portion, and the non-light-transmitting area being provided around the bearing surface 24 to form an edge structure thereof. That is, the upper shell 22 may be manufactured by, for example, secondary injection molding. In this way, the fill light is only transmitted from the bearing surface 24 area, thereby reducing the leakage of the fill light from other locations and improving the utilization rate of light. This application is not limited to this.

[0053] Furthermore, the upper shell 22 includes a translucent matrix 221 and a light-distributing structure embedded in the translucent matrix 221. It should be noted that the translucent matrix 221 forms the above-mentioned bearing surface 24. The translucent matrix 221 can be injection-molded from the above-mentioned PC, PMMA and other materials, and the light-distributing structure can be a light-distributing powder. Specifically, before injection molding, the light-distributing powder is mixed into a plastic material such as PC or PMMA, and then the upper shell 22 is injection-molded as a whole. The light-distributing structure can make the light presented softer and more uniform, and the light-distributing powder can also make the translucent part have a certain color, similar to milky white, which can form a certain shielding effect, and the user cannot see the specific structure inside the shell 21, which has better aesthetics. Among them, the light-distributing powder can be in the form of silica gel powder, titanium dioxide powder, zinc oxide powder, aluminum oxide powder, etc., and this application does not limit this.

[0054] Please refer to Figure 3In some embodiments, the light-transmitting substrate 221 is formed with a light-distributing recess 222. Specifically, the first light source 25 can be an LED array light source, which includes a plurality of LED lamp beads arranged in an array, and one light-distributing recess 222 can be provided corresponding to one LED lamp bead, so that the light emitted by each LED lamp bead is evenly distributed and diffused by the light-distributing recess 222, thereby reducing the light spot and shadow effects. Specifically, the upper surface of the light-transmitting substrate 221 forms the above-mentioned bearing surface 24, and the lower surface thereof, i.e., the inner surface located in the mounting cavity, forms the light-distributing recess 222. The light-distributing recess 222 can be roughly arc-shaped, and the light can be evenly diffused through the arc-shaped surface of the light-distributing recess 222. Please refer to Figure 4 In some embodiments, a light-distributing convex portion 223 may be formed on the light-transmitting substrate 221. The light-distributing convex portion 223 may be a microstructure or a microprism array formed on the light-transmitting substrate 221. Furthermore, a protective layer 224 may be provided on the side of the light-transmitting substrate 221 where the light-distributing convex portion 223 is provided to protect the light-distributing convex portion 223. The protective layer 224 may be made of the same material as the light-transmitting substrate 221 or a different material, and this application does not impose any restrictions thereto.

[0055] In one embodiment, the first light source 25 is an LED light film, which includes an LED array light source and an optical film arranged in the light emitting direction of the LED array light source. The optical film can be in the form of a lens array film, a diffraction film, a microstructure film, etc., and this application does not impose any restrictions on this. In this way, the first light source 25 is roughly flat and forms a surface light source. It can be easily installed in the installation cavity and can emit relatively uniform light below the bearing surface 24 to improve the fill light effect. It can be understood that, as mentioned above, when the first light source 25 can be an LED array light source, it is flatly arranged in the installation cavity, which also constitutes a surface light source.

[0056] Please refer back to Figure 1 In some embodiments, a second light source 30 is further included. The second light source 30 is mounted on the housing 110 and is used to illuminate the object to be photographed placed on the supporting surface 24 from top to bottom for fill light. It is understandable that for some opaque objects to be photographed, or some relatively thick books, the first light source 25 cannot play the role of fill light. In this application, the second light source 30 is provided to provide fill light for these objects. In some structural forms, the video stand 1 may also include a bracket structure, which is connected to the housing 110 and is used to assemble the second light source 30. The irradiation direction of the second light source 30 is adjusted by adjusting the bracket structure.

[0057] In some structural forms, see Figure 1 and Figure 5The housing 110 includes a main body 111 and a protrusion 112 fixed together. The protrusion 112 is provided on one side of the main body 111. The support plate assembly 20 is connected to the main body 111. The support plate assembly 20 and the protrusion 112 are located on the same side of the main body 111 and are spaced apart in the vertical direction of the main body 111. In one embodiment, the protrusion is connected to a side of the main body 111 close to the support plate assembly 20 and extends away from the main body 111. The camera assembly 130 and the second light source 30 are both mounted on the protrusion 112.

[0058] Among them, the protrusion 112 is connected to the upper part of the main body 111, and the pallet assembly 20 is connected to the bottom of the main body 111, so that the protrusion 112 can be separated from the object to be photographed on the supporting surface 24 of the pallet assembly 20 below by a certain distance, thereby making the camera assembly 130 have a larger shooting range, and the effective shooting pixels of the camera assembly 130 can cover the entire supporting surface 24.

[0059] It is understandable that the upper end of the protrusion 112 can be flush with the upper end of the main body 111. Of course, the upper end surface of the protrusion 112 can also be set higher than the upper end surface of the main body 111, or the upper end surface of the protrusion 112 can also be set lower than the upper end of the main body 111. This is not limited in this application. Generally, the center distance of the protrusion 112 of this application from the lower end of the main body 111 can be 300 mm to 500 mm. This can improve the versatility of the entire video booth 1. Because such a distance setting makes the overall size of the entire video booth 1 not too large, it can also clearly capture items such as A3 paper and A4 paper on the pallet assembly 20 below the protrusion 112, which has a better use effect.

[0060] The protrusion 112 of the present application is fixedly connected to the main body 111, and is a connection form that cannot rotate with each other, that is, the protrusion 112 is a structure different from the arm body in the arm video display stand 1. In this embodiment, the inner cavities of the main body 111 and the protrusion 112 are connected to form an integral installation cavity. In one configuration, the control board and the camera assembly 130 are both installed in the inner cavity of the protrusion 112. This configuration allows the camera assembly 130 and the control board to be close to each other, so that there is no need for a long data cable and an adapter plate to achieve electrical connection between the two. This can simplify the structure of the video display stand 1 and reduce its cost. Of course, the camera assembly 130 and the control board are both located in the inner cavity of the protrusion 112, which makes the wiring between the two shorter and also improves the stability of the electrical connection.

[0061] In one embodiment, the protrusion 112 and the main body 111 are integrally formed. That is, the protrusion 112 and the main body 111 can be separate parts of the same housing. This makes the connection between the protrusion 112 and the main body 111 more secure and reduces the number of assembly steps. Alternatively, the protrusion 112 and the main body 111 can be manufactured separately and then fixedly connected by bonding, welding, screws 45, or the like.

[0062] In some embodiments, see Figures 5 to 10 , the rotating shaft 50 includes a first shaft segment 51 and a second shaft segment 52, one of the housing 110 and the pallet assembly 20 is fixedly connected to the first shaft segment 51, and the other is rotatably mounted on the second shaft segment 52. Exemplarily, the pallet assembly 20 is fixedly connected to the first shaft segment 51, and the housing 110 is rotatably connected to the second shaft segment 52. Among them, the first shaft segment 51 and the pallet assembly 20 can be fixed together by threaded fasteners. Of course, the rotating shaft 50 can also be fixedly connected to the pallet assembly 20 by means of clamping, bonding, etc. Here, the specific form of the first shaft segment 51 is not limited in this application. In other embodiments, the housing 110 is fixedly connected to the first shaft segment 51, and the pallet assembly 20 is rotatably mounted on the second shaft segment 52. This application does not limit this.

[0063] In order to relatively fix the support plate assembly 20 in the folded state, please refer to Figure 6 The embodiment of the present application further includes a damping structure 40, which is sleeved around the second shaft segment 52 and located between the exhibition stand body 10 and the support plate assembly 20. The damping structure 40 is configured to provide a damping force when the support plate assembly 20 is closed relative to the exhibition stand body 10. The damping structure 40 provides additional damping force, making the support plate assembly 20 more stable in the collapsed state and less susceptible to external vibration or impact.

[0064] In some structural forms, see Figures 6 to 9The damping structure 40 includes an elastic member 41 and a friction member 42. The elastic member 41 is slidably arranged in the axial direction of the second shaft segment 52 and is fixed relative to the second shaft segment 52 in the circumferential direction of the second shaft segment 52. The friction member 42 is fixedly connected to the housing 110 and can be rotated relative to the second shaft segment 52. The elastic member 41 includes a first surface 413 facing the friction member 42, and the friction member 42 includes a second surface 422 facing the elastic member 41. One of the first surface 413 and the second surface 422 is provided with a boss 43, and the other of the two is provided with a groove 44. When the support plate assembly 20 is in the retracted state, the boss 43 is snapped into the groove 44. Specifically, in the process of switching the pallet assembly 20 from the expanded state to the folded state, the boss 43 will first contact the first surface 413 or the second surface 422, and after the pallet assembly 20 rotates to a certain angle, the boss 43 will partially enter the groove 44, and after the elastic extrusion of the elastic member 41, the boss 43 is inclined in the groove 44, and after the pallet assembly 20 is further rotated to a certain angle, the elastic extrusion of the elastic member 41 enables the boss 43 to slide along the slope of the groove 44 until the boss 43 is completely stuck in the groove 44.

[0065] Of course, in other embodiments, the damping structure 40 may be a damping ring made of materials such as silicone and rubber.

[0066] In the present application, the elastic extrusion of the elastic member 41 and the friction member 42 can provide a damping force during the rotation of the support assembly 20 and the housing 110, and by respectively arranging a boss 43 and a groove 44 on the facing surfaces of the elastic member 41 and the friction member 42, the support assembly 20 can be automatically closed and locked after being retracted to a certain angle.

[0067] For further information, see Figures 7 to 9 The elastic member 41 includes a spring clip 411 and an adjusting member 412. The adjusting member 412 is provided with a boss 43, and the friction member 42 is provided with a groove 44. The spring clip 411 drives the adjusting member 412 toward the friction member 42. There can be one or more spring clips 411. Exemplarily, there are multiple spring clips 411. Multiple spring clips 411 can evenly distribute force, thereby applying a more balanced force to the adjusting member 412. This can reduce the problem of local stress concentration and improve the stability and durability of the system.

[0068] In one embodiment, in order to facilitate the relative fixation of the friction member 42 and the housing 110, please refer to Figures 7 to 9The friction member 42 is provided with an assembly portion 421, and a fixing hole 113 is provided on the housing 110, and the assembly portion 421 is inserted into the fixing hole 113. In one embodiment, the assembly portion 421 is a block structure. After the block structure is inserted into the fixing hole 113, a stable connection can be formed between the friction member 42 and the housing 110. This connection method only requires the first shaft segment 51 to be inserted into the fixing hole 113 to complete the fixation of the friction member 42, without the need for additional tools or complicated operating steps, thereby reducing the difficulty and cost of installation. Moreover, by inserting the first shaft segment 51 into the fixing hole 113, the connection between the friction member 42 and the housing 110 is more compact and beautiful. The absence of exposed screws or connectors makes the appearance of the system neater, improving the aesthetics and quality of the product.

[0069] In one embodiment, in order to facilitate the adjustment of the damping force between the elastic member 41 and the friction member 42, please continue to refer to Figures 7 to 9 The embodiment of the present application further includes a threaded member 45 having an internal thread. The end of the second shaft section 52 of the rotating shaft 50 away from the first shaft section 51 is provided with an external thread. The internal thread of the threaded member 45 is connected to the external thread and is movable in the axial direction of the rotating shaft 50. The threaded member 45 is used to apply pressure to the elastic member 41 toward the friction plate. By rotating the threaded member 45, the threaded member 45 can be moved. By moving the threaded member 45, the pressure between the elastic member 41 and the friction member 42 can be adjusted, thereby adjusting the damping force between the elastic member 41 and the friction member 42.

[0070] To facilitate the installation and connection of the support assembly 20 and the housing 110 with the rotating shaft 50, the support assembly 20 includes a first bracket 26 fixedly connected to the first shaft segment 51. The exhibition stand body 10 includes a second bracket 140 fixedly connected to the housing 110. The second bracket 140 is provided with a shaft hole, and the second shaft segment 52 is rotatably connected to the shaft hole. The arrangement of the first bracket 26 and the second bracket 140 simplifies the fixing of the support assembly 20 to the first shaft segment 51, while the second shaft segment 52 can rotate within the shaft hole, thereby enabling the support assembly 20 to rotate relative to the housing 110.

[0071] It can be understood that the support plate assembly 20 has a bearing surface 24. When the support plate assembly 20 is in the unfolded state, please refer to Figure 1 , books, test papers and other items that need to be photographed by the camera assembly 130 can be placed on the carrying surface 24. When the support plate assembly 20 is in the folded state, please refer to Figure 11, the supporting surface 24 will move toward the main body 10 of the exhibition stand. However, the supporting surface 24 of the embodiment of the present application is arranged at an angle to the vertical direction and is tilted toward the housing 110. This arrangement allows the closed support plate assembly 20 to maintain a negative angle when folded. In other words, the support plate assembly 20 maintains a safe angle when folded and does not flip outward, which is more conducive to maintaining the stability of the closed state of the support plate assembly 20.
