DETAILED DESCRIPTION

[0034] The embodiment of the present application discloses a digital human live broadcast cabin. Through the setting of the screen control assembly 7, when the green screen body 8 is in a lowered state, the anti-wrinkle control plate 701 in the screen control assembly 7 will follow the movement of the green screen body 8 to prevent the green screen body 8 from being stuck. When the green screen body 8 rises and retracts, the anti-wrinkle control plate 701 fits tightly against the green screen body 8, so that the anti-wrinkle control plate 701 can smooth out the wrinkles on the green screen body 8, thereby improving the cutout effect and picture quality.

[0035] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0036] Example 1:

[0037] Reference Figure 1 、 Figure 2 、 Figure 4 and Figure 9, the embodiment of the present application discloses a digital human live broadcast cabin, including a screen smoothing component 7 for smoothing the green screen body 8, the screen smoothing component 7 includes an anti-wrinkle smoothing plate 701, the anti-wrinkle smoothing plate 701 is arranged in an arc shape, and the anti-wrinkle smoothing plate 701 is arranged in contact with the green screen body 8, and a screen roller 504 is rotatably arranged on one side of the bottom end of the protective screen shell 5, and the screen roller 504 is rolled on the other side of the green screen body 8, and short spring columns 7011 are fixedly arranged on both sides of the anti-wrinkle smoothing plate 701, and a supporting frame 705 is rotatably arranged on the outer side of the short spring column 7011, and the supporting frame 705 is detachably arranged on one side of the protective screen shell 5, and a torsion spring 7012 is fixedly arranged on the outer side of the short spring column 7011, and the other end of the torsion spring 7012 is fixedly connected to the supporting frame 705.

[0038] When the green screen body 8 is retracted, the green screen body 8 will generate an upward pulling force on the anti-wrinkle soothing plate 701 in the soothing screen assembly 7 when it rises, so that the anti-wrinkle soothing plate 701 continues to be in close contact with the green screen body 8. At this time, the torsion spring 7012 is in a contracted state, which makes it easier for the anti-wrinkle soothing plate 701 to be in close contact with the green screen body 8. The surface where the anti-wrinkle soothing plate 701 contacts the green screen body 8 is an arc surface to prevent the green screen body 8 from being scratched, so that the anti-wrinkle soothing plate 701 can smooth out the wrinkles on the green screen body 8, thereby improving the cutout effect and picture quality.

[0039] In this embodiment, limiting slides 702 are fixedly provided on both sides of the anti-wrinkle soothing plate 701, and side fixed plates 703 are slidingly provided on the outer sides of the limiting slides 702. The side fixed plates 703 are fixedly provided on one side of the supporting frame 705, and a waist arc sliding groove 704 is opened on one side of the side fixed plate 703.

[0040] Among them, the opening of the waist arc slide groove 704 can limit the sliding range of the limiting slide column 702, thereby displaying the movable range of the anti-wrinkle plate 701, preventing the anti-wrinkle plate 701 from leaving the green screen body 8, and does not affect the recovery and release of the green screen body 8.

[0041] Reference Figure 1 、 Figure 2 、 Figure 5 and Figure 7 , and also includes a protective screen shell 5 for storing the green screen body 8. The protective screen shell 5 is used to store the green screen body 8. The protective screen shell 5 is detachably arranged on the inner top of the live broadcast cabin body 1 through the top fixing frame 2. A winding roller 501 is rotatably arranged on the inner side of the protective screen shell 5, and the green screen body 8 is fixedly arranged on the outer side of the winding roller 501. Second wheels 502 are fixedly arranged at both ends of the winding roller 501, and the end faces of the second wheel 502 that are away from each other are eccentrically rotated with a wheel connecting rod 503.

[0042] When the green screen body 8 is recovered, the winding roller 501 rotates under the drive of the second wheel 502, so that the green screen body 8 can be wound around the outside of the winding roller 501. The rotation of the second wheel 502 is driven by the wheel connecting rod 503, the first wheel 409 and the gear plate 410.

[0043] The four corners of the bottom of the live broadcast cabin body 1 are fixed with standing columns 101, and the bottom of the live broadcast cabin body 1 is symmetrically provided with electric telescopic rods 9. The ends of the electric telescopic rods 9 that are away from each other are fixed with connecting rotating frames 902, and the side of the connecting rotating frames 902 that are away from each other is rotatably provided with a wheel frame 901, and the wheel frame 901 is rotatably provided at the bottom of the live broadcast cabin body 1.

[0044] A movable wheel is provided on one side of the wheel frame 901 to facilitate the movement of the live broadcast cabin body 1. When the live broadcast cabin body 1 needs to be stopped somewhere, the four electric telescopic rods 9 are started to make the angle between the wheel frame 901 and the bottom of the live broadcast cabin body 1 smaller and smaller, so that the standing column 101 can contact the ground, so that the live broadcast cabin body 1 can stand stably at the current position.

[0045] Example 2:

[0046] Reference Figure 1 、 Figure 2 、 Figure 6 、 Figure 7 and Figure 8 A tensioning structure 6 is provided on the other side of the protective screen shell 5 and the green screen body 8. The tensioning structure 6 includes a hanging tooth plate 601. A linkage gear ring 602 is meshed on one side of the hanging tooth plate 601. A receiving screw barrel 604 is passed through and fixed on one end of the linkage gear ring 602. The inner sides of the two ends of the receiving screw barrel 604 are threadedly connected with side top screws 605. A connecting rod block 606 is fixed on the side away from each other of the side top screws 605. A second connecting plate 608 is rotatably provided on the side of the connecting rod block 606 close to the green screen body 8. The end of the second connecting plate 608 is rotatably provided with a first connecting plate 607. The second connecting plate 608 is rotatably provided on one side of the protective screen shell 5. The other end of the first connecting plate 607 is rotatably provided with a connecting screen horizontal plate 609. The connecting screen horizontal plate 609 is fixedly provided on the bottom side of the green screen body 8.

[0047] When the green screen body 8 is retracted, the screen connecting horizontal plate 609 will rise. Due to the connection between the first connecting plate 607, the second connecting plate 608 and the second connecting plate 608, the side top screw 605 and the storage screw barrel 604 will also rise synchronously. The rise of the storage screw barrel 604 will be achieved through the coordinated rotation of the linkage gear ring 602 and the hanging gear plate 601, so that the side top screw 605 enters the storage screw barrel 604 while rising, making the angle between the first connecting plate 607 and the second connecting plate 608 smaller, making it easier for the green screen body 8 to be retracted more smoothly.

[0048] When the green screen body 8 is released, the connecting horizontal plate 609 will drop due to its own gravity, and the reversal of the winding roller 501 will release the green screen body 8. The angle between the first connecting plate 607 and the second connecting plate 608 will gradually increase, so that the green screen body 8 can be tightened during use, thereby improving the flatness of the green screen body 8 during use, making the virtual background smoother and more natural during production.

[0049] Furthermore, the hanging tooth plate 601 is detachably provided on the top of the protective curtain housing 5 , and a sliding bracket 603 is rotatably provided on the outer side of the receiving screw barrel 604 , and the sliding bracket 603 is slidably provided on the other side of the hanging tooth plate 601 .

[0050] The arrangement of the hanging tooth plate 601 facilitates the use in conjunction with the linkage gear ring 602 , and the sliding bracket 603 enables the storage screw barrel 604 to rotate stably during use.

[0051] Example 3:

[0052] Reference Figure 2 、 Figure 3 、 Figure 4 and Figure 5 , including a soot blowing assembly 4 for cleaning dust on the surface of the green screen body 8, the soot blowing assembly 4 includes a convex rotating frame 401, and a plurality of convex rotating frames 401 are provided. The other end of the convex rotating frame 401 is rotatably provided with a continuous drive rotating plate 402, and the other end of the continuous drive rotating plate 402 is rotatably provided with a connecting member 403, and a piston 404 is fixedly provided on the other side of the connecting member 403, and a blowing pipe 405 is slidingly provided on the outer side of the piston 404, and a connecting support plate 407 is fixedly provided on the outer side of the blowing pipe 405, and the connecting support plate 407 is fixedly provided on one side of the protective screen shell 5, and the other end of the blowing pipe 405 is fixedly provided with an air outlet horizontal pipe 406, and the air outlet horizontal pipe 406 is provided on one side of the green screen body 8.

[0053] The motor 3 drives the gear plate 410 in the soot blowing assembly 4 to rotate. The rotation of the gear plate 410 drives the second wheel plate 502 to rotate through the wheel connecting rod 503. The second wheel plate 502 can drive the winding roller 501 to rotate. The winding roller 501 will wrap the green screen body 8 around its outside. At the same time, the rotation of the gear plate 410 drives the convex rotating frame 401, the continuous drive short rod 408 and the receiving rotating rod 201 to rotate together. The rotation of the convex rotating frame 401 will cause the piston 404 to produce piston movement through the continuous drive rotating plate 402 and the connecting member 403. The piston 404 will cause air to be blown out from the opening of the air outlet cross pipe 406 to the green screen body 8, thereby blowing away the dust on the surface of the green screen body 8, making the green screen body 8 cleaner when used next time, improving the cleanliness of the green screen body 8, and thus improving the quality of virtual imaging.

[0054] For further information, see Figure 4The end of the short drive rod 408 close to each other is fixed with a connecting rod 201, which passes through and is rotatably arranged on one side of the top fixing frame 2, and the top fixing frame 2 is fixedly arranged on the top of the protective curtain shell 5.

[0055] The connecting rotating rod 201 can be connected to the continuous driving short rods 408 at both ends to drive the continuous driving short rods 408 and the convex rotating frame 401 to rotate, so that the soot blowing assembly 4 can perform the blowing work.

[0056] See Figure 3 and Figure 4 , both sides of the end of the convex rotating frame 401 are fixed with a continuous driving short rod 408, and the ends of the continuous driving short rod 408 away from each other are respectively fixed with a first wheel plate 409 and a gear plate 410, and the other end faces of the first wheel plate 409 and the gear plate 410 are eccentrically rotated to set a wheel connecting rod 503, and the outer side of the gear plate 410 is meshed with a driving gear 301, and one end of the driving gear 301 is provided with a motor 3, and the driving gear 301 is fixed to the driving end of the motor 3, and the motor 3 is fixed to the top of the live broadcast cabin body 1.

[0057] By starting the motor 3 , the motor 3 drives the driving gear 301 to rotate, and the rotation of the driving gear 301 drives the gear plate 410 to rotate, thereby driving the soot blowing assembly 4 to operate and provide the required power for the recovery of the green screen body 8 and the tensioning structure 6 .

[0058] Working principle: A moving wheel is connected to one side of the wheel frame 901, and the live broadcast cabin body 1 can be moved to different positions for use through the moving wheel, thereby improving the flexibility of the live broadcast cabin body 1 when in use. When the live broadcast cabin body 1 needs to be stopped at a certain place, the four electric telescopic rods 9 are started to make the angle between the wheel frame 901 and the bottom of the live broadcast cabin body 1 smaller and smaller, so that the standing column 101 can contact the ground, so that the live broadcast cabin body 1 can stand stably at the current position;

[0059] When the green screen body 8 is recovered, the motor 3 drives the driving gear 301 to rotate. The rotation of the driving gear 301 drives the gear plate 410 in the soot blowing assembly 4 to rotate. The rotation of the gear plate 410 drives the second wheel plate 502 to rotate through the wheel connecting rod 503. The second wheel plate 502 can drive the winding roller 501 to rotate. The winding roller 501 will wrap the green screen body 8 around its outer side. At the same time, the rotation of the gear plate 410 drives the convex rotating frame 401, the continuous driving short rod 408 and the receiving rotating rod 201 to rotate together. The rotation of the convex rotating frame 401 will cause the piston 404 to generate piston movement through the continuous driving rotating plate 402 and the connecting member 403. The piston 404 will force air to be blown out from the opening of the air outlet horizontal pipe 406 toward the green screen body 8, thereby blowing away the dust on the surface of the green screen body 8, making the green screen body 8 cleaner when used next time, improving the cleanliness of the green screen body 8, and thus improving the quality of virtual imaging.

[0060] When the green screen body 8 rises, it will generate an upward pulling force on the anti-wrinkle plate 701 in the screen assembly 7. Due to the setting of the limiting slide 702 and the waist arc slide groove 704, the limiting slide 702 slides on the inner side of the waist arc slide groove 704, so that the anti-wrinkle plate 701 continues to be in close contact with the green screen body 8. At this time, the torsion spring 7012 is in a contracted state, which makes it easier for the anti-wrinkle plate 701 to be in close contact with the green screen body 8. And relying on the setting of the screen roller 504, the green screen body 8 can smoothly enter the protective screen housing 5 and be wound up by the winding roller 501 for recycling. When the green screen body 8 is recycled, it will rotate due to the friction between the green screen body 8 and the screen roller 504, which is convenient for use with the anti-wrinkle plate 701.

[0061] When the green screen body 8 is retracted, the screen connecting horizontal plate 609 in the tensioning structure 6 will be lifted up, and the linkage gear ring 602, the sliding connecting frame 603 and the receiving screw barrel 604 will also be lifted up. When the linkage gear ring 602 is lifted up, it will rotate in cooperation with the hanging gear plate 601, so that the rotation of the linkage gear ring 602 will drive the receiving screw barrel 604 to rotate. The rotation of the receiving screw barrel 604 allows the side top screw 605 to enter the receiving screw barrel 604, and makes the angle between the first connecting plate 607 and the second connecting plate 608 gradually become smaller, so that the green screen body 8 can be put into the storage barrel 604. The first connecting plate 607 and the second connecting plate 608 will be folded up, and the screen connecting horizontal plate 609 will be close to the protective screen shell 5. The protective screen shell 5 is used to store the green screen body 8. When the green screen body 8 is released, the screen connecting horizontal plate 609 will drop due to its own gravity, and the reversal of the winding roller 501 will release the green screen body 8. The angle between the first connecting plate 607 and the second connecting plate 608 will gradually increase, so that the green screen body 8 can be tensioned during use, thereby improving the flatness of the green screen body 8 during use, making the virtual background smoother and more natural during production.

[0062] Obviously, those skilled in the art may make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if such changes and modifications fall within the scope of the claims and their equivalents, the present invention is intended to include such changes and modifications.
