[0013] As a preferred technical solution of the interactive digital human live streaming device of the present invention, the snap-fit ​​block is tightly embedded in the snap-fit ​​groove, and multiple segmented tracks are combined and spliced ​​into a ring shape, with the bottom of the segmented tracks fitting and connected in the arrangement groove.

[0014] Compared with the prior art, the present invention provides an interactive digital human live streaming device, which has the following beneficial effects: 1. A set of drive boxes drives the main body of the live streaming device, high-precision camera and holographic projector to slide along a circular track spliced ​​with multiple segments. At the same time, another set of drive boxes drives the screen to slide synchronously. The screen is positioned relative to the high-precision camera and holographic projector and keeps them collinear. This replaces the traditional method of recording a person sitting still. It keeps the position of the recording equipment and the person dynamically aligned, so that the person is in the center of the recording screen. This improves the quality of the subsequent digital human production and ensures the effect of the digital human in the subsequent interactive live streaming process. The system utilizes support columns, lifting hydraulic cylinders, and a support platform to ensure stable support for the main body of the live streaming device and the screen. The lifting hydraulic cylinders drive the support platform to rise and fall, while the support columns limit the rise and fall to ensure stability. The support positions of the main body of the live streaming device and the screen can be adjusted to meet specific needs. Furthermore, the holographic projector allows for changes to the video background, facilitating background adjustments as required and meeting the flexible recording needs of live video. Infrared sensor arrays detect the movement of the live streamer's body parts, and when the live streamer moves during recording, the infrared sensor array transmits the target movement signal to the controller inside the main body of the live streaming device.

[0015] 2. The circulation pump is started by the controller, which guides the hydraulic fluid in the corresponding hydraulic chamber to the pushing chamber. Under the action of hydraulic pressure, the moving block is pushed, and the supporting spring on one side is stretched and the supporting spring on the other side is compressed. By moving the moving block, the connecting hole on its pushing side is opened, so that the hydraulic fluid enters the rotating cavity and drives the drive wheel to rotate. The drive gear connected to its coaxial axis moves along the segmented track, so that the main body of the live broadcast device at the top of the drive box can move synchronously with the live broadcast device. At the same time, the drive box and drive gear on the screen side will also drive the screen to move synchronously, maintaining the dynamic alignment between the screen and the main body of the live broadcast device. Both sides of the drive box can drive the drive wheels to rotate, facilitating the reciprocating movement of the drive box along the segmented track. Simultaneously, the hydraulic drive allows for easy control of the hydraulic fluid input, converting the hydraulic fluid input into the number of rotations of the drive wheels. This makes the displacement distance of the two drive boxes controllable, ensuring the collinearity of the screen and the main body of the live broadcast device with the recorded person, avoiding the phenomenon of being out of the frame, and improving the recording effect.

[0016] The hydraulic fluid drives the drive wheel and drive gear to rotate. When a meshing deviation occurs between the drive gear and the segmented track, the drive gear is subjected to a reaction force that is transmitted to the drive wheel. When the hydraulic fluid drives the drive wheel to rotate, the drive wheel can transmit the meshing deviation force to the hydraulic fluid. The hydraulic fluid buffers and dilutes the force, keeping the drive gear stable when it meshes and moves along the segmented track, thus preventing shaking during the recording process.

[0017] 3. By splicing the support rods to the inside of the base and top frames, the screen support mechanism can be quickly extended, assembled, and disassembled. Combined with the detachable base, it is easy to store after use. The rollers in the two roll boxes, along with the turntable and limit bolts, facilitate the winding and unwinding of the screen, making it easy to lay the screen flat when in use and roll it up when not in use. At the same time, the flat laying limiting mechanism composed of through grooves, limit guide rollers, support guide rollers, and guide grooves can restrict the position of the screen, making it lay flat and ensuring a flat projection effect.

[0018] 4. The snap-fit ​​slots and snap-fit ​​blocks facilitate quick and precise assembly of adjacent track segments, ensuring assembly accuracy. Simultaneously, the track slots, combined with the inner support frame, rotating frame, and track wheel support mechanism, as well as the outer support mechanism composed of the outer support frame and fitting arc blocks, facilitate guiding and limiting the position of the drive box during displacement, ensuring the positional accuracy of the drive box movement and improving the stability of the recording equipment and screen on the drive box. Warning strips provide alerts, and the arrangement slots facilitate the placement of multiple segmented track assemblies in a circular track, ensuring stability and facilitating subsequent disassembly and transportation.

A gear frame 12 is installed on one side of the drive box 3. A drive gear 13 that meshes with the segmented track 2 is rotatably installed on the inner side of the gear frame 12. A rotating shaft 14 is installed at the center point of the drive gear 13. A rotating cavity 15 is provided on the other side of the drive housing 3. A drive wheel 16, coaxially connected to the rotating shaft 14, is embedded inside the rotating cavity 15. Drive blades 17 are evenly distributed on the edge of the drive wheel 16. A pushing cavity 18 is provided inside the drive housing 3 at the top of the rotating cavity 15. A movable plug 19 is slidably connected inside the pushing cavity 18. Communicating holes 20 are provided on both sides of the top of the rotating cavity 15, communicating with the pushing cavity 18.

The circulating pump 25 is controlled by the controller integrated inside the live broadcast device body 4. By moving the movable plug 19, the connecting hole 20 on its pushing side is opened, so that the hydraulic fluid enters the rotating cavity 15, which facilitates the rotation of the drive wheel 16. The side of the movable plug 19 is connected to the inner wall of the push cavity 18 through the support spring 21. The two side walls of the push cavity 18 are respectively connected to the push tube 22. The control box 11 is equipped with a hydraulic chamber 23 for filling with hydraulic fluid. The hydraulic chamber 23 is equipped with a delivery pipe 24 connected to the push pipe 22, and the inlet end of the delivery pipe 24 is connected to a circulation pump 25.

[0034] The base frame 8 is connected to the support platform 28 at the corresponding position via the detachable base 35 at its bottom. The inner side of the roll box 9 is rotatably connected to the roll roller 36, and one end of the roller roller 36 is connected to the turntable 37 at the outer position of the roll box 9. The roller roller 36 is connected to the limiting bolt 38 that limits its position. The top of the roll box 9 is provided with a through slot 39 for the curtain 10 to pass through and move. The top of both sides of the base frame 8 are rotatably connected to the limiting guide rollers 40. Both sides of the base frame 8 and the top frame 43 are provided with matching slots 41.

The flat laying limiting mechanism composed of the slot 39, the guide roller 40, the support guide roller 44 and the guide slot 45 can limit the position of the curtain 10, thereby making it laid flatter.

[0035] Supporting guide columns 26 are connected to the top corners of the drive box 3. A lifting hydraulic cylinder 27 is fixedly installed at the top center of the drive box 3. A support platform 28 is fixedly connected to the top telescopic end of the lifting hydraulic cylinder 27. The support platform 28 has guide holes at its corners, and the support guide column 26 slides along the guide holes. The main body 4 of the live broadcast device is detachably installed on the support platform 28. The bottom of the main body 4 of the live broadcast device is detachably connected to the support platform 28 through the base. The support platform 28 is raised and lowered by the lifting hydraulic cylinder 27. The support guide column 26 limits its raising and lowering position to ensure stability. The support position of the main body 4 of the live broadcast device and the screen 10 can be easily changed by adjustment.

[0036] The inner and outer arc edges of the segmented track 2 are provided with track grooves 29. The side end of the gear frame 12 is connected to an inner support 30. The bottom end of the inner support 30 is connected to a rotating frame 31 corresponding to the track groove 29. The inner side of the rotating frame 31 is rotatably connected to a track wheel 32 that fits and rolls along the track groove 29. An outer bracket 33 is installed at the bottom of the drive box 3. The end of the outer bracket 33 is connected to a fitting arc block 34 that slides along the track groove 29. The side of the track wheel 32 is in contact with the inner wall of the track groove 29 and the track wheel 32 rolls along the track groove 29. The inner arc surface of the fitting arc block 34 is a smooth surface and slides along the inner wall of the track groove 29. This facilitates the drive box 3 to be guided and restricted in its position by the track wheel 32 and the fitting arc block 34 when it is displaced, thus ensuring the positional accuracy of the drive box 3.

[0037] One side of the segmented track 2 is provided with a snap-fit ​​groove 46, and the other side is connected with a snap-fit ​​block 47. Adjacent segmented tracks 2 are combined and spliced ​​together by snap-fit ​​block 47 and snap-fit ​​groove 46. The edge of the information source recording platform 1 is provided with a raised warning strip 48, and the side of the information source recording platform 1 is provided with an arrangement groove 49 that cooperates with the segmented track 2. The snap-fit ​​block 47 is tightly embedded in the snap-fit ​​groove 46. Multiple segmented tracks 2 are combined and spliced ​​together in a ring shape. The bottom of the segmented track 2 fits into the arrangement groove 49. The snap-fit ​​groove 46 and snap-fit ​​block 47 facilitate the quick and accurate combination and splicing of adjacent segmented tracks 2, ensuring assembly accuracy. The arrangement groove 49 is used to conveniently place the ring track assembled from multiple segmented tracks 2, ensuring stability.

[0038] The working principle and usage process of this invention are as follows: First, the adjacent two segmented tracks 2 are quickly spliced ​​into a ring track by using the snap-fit ​​grooves 46 and snap-fit ​​blocks 47 on both sides of the segmented track 2. The ring track assembled by multiple segmented tracks 2 is placed using the arrangement grooves 49 to ensure stability. Through the track grooves 29 on the inner and outer sides of the segmented track 2, combined with the inner bracket 30, rotating frame 31 and track wheel 32 installed on the gear frame 12, and the outer bracket 33 and fitting arc block 34 installed at the bottom of the drive box 3, the position of the drive box 3 can be guided and restricted when it moves, and the positional accuracy of the drive box 3 movement can be ensured to ensure the stability of the recording equipment and screen 10 on the drive box 3. The support guide column 26, lifting hydraulic cylinder 27 and support platform 28 ensure stable support of the live broadcast device body 4 and screen 10. The lifting hydraulic cylinder 27 drives the support platform 28 to rise and fall, and the support guide column 26 limits its rising and falling position. The support position of the live broadcast device body 4 and screen 10 can be changed by adjustment, which can be adapted to meet the needs. When the live streamer is stationary during recording, the live streamer main body 4, high-precision camera 6, holographic projector 7 and screen 10 on the two drive boxes 3 remain different to achieve static recording. When the live streamer needs to move during recording, the warning strip 48 on the side of the circular platform 1 is recorded through the information source to provide warnings when the live streamer moves. The infrared sensor array 50 is used to detect the body parts of the live streamer. When the live streamer moves during the recording process, the infrared sensor array 50 transmits the target movement signal to the controller in the live streamer main body 4, and the circulation pump 25 is started based on the controller. After the circulation pump 25 is started, the hydraulic fluid in the corresponding hydraulic chamber 23 is guided to the push chamber 18 through the circulation pump 25, the delivery pipe 24 and the push pipe 22. Under the action of hydraulic pressure, the moving block 19 is pushed and the support spring 21 on one side is stretched and the support spring 21 on the other side is compressed. When the moving block 19 moves, the connecting hole 20 on its pushing side is in a conductive state, so that the hydraulic fluid enters the rotating cavity 15 through the connecting hole 20, which drives the drive wheel 16 to rotate, and the drive gear 13 coaxially connected to the drive wheel 16 rotates. The drive gear 13 drives the drive box 3 to move and dynamically adjust along the segmented track 2, so that the live broadcast device main body 4, high-precision camera 6 and holographic projector 7 installed on the top of the drive box 3 can move synchronously with the real person. At the same time, the drive box 3 and drive gear 13 on the side of the screen 10 will also drive the screen 10 to move synchronously, maintaining the dynamic alignment between the screen 10 and the live broadcast device main body 4. During the drive adjustment process, the two sets of control side boxes 11 on both sides of the two drive boxes 3 can drive the drive wheel 16 to rotate, which facilitates the reciprocating movement of the drive box 3 along the segmented track 2. With the help of hydraulic drive, the input amount of hydraulic fluid is controlled, which can be converted into the number of rotations of the drive wheel 16. This makes the displacement distance of the two drive boxes 3 controllable, ensuring the collinearity of the positions of the screen 10 and the main body of the live broadcast device 4 on the two drive boxes 3 with the recording live person, and avoiding the phenomenon of separation from the screen. Furthermore, the drive wheel 16 and the drive gear 13 are driven to rotate by the hydraulic fluid. When there is a meshing deviation between the drive gear 13 and the segmented track 2, the drive gear 13 receives a reaction force and transmits it to the drive wheel 16. When the drive wheel 16 is driven to rotate by the hydraulic fluid, the drive wheel 16 transmits the meshing deviation force to the hydraulic fluid. The hydraulic fluid buffers and dilutes the force, keeping the drive gear 13 stable when it is meshing and displacing along the segmented track 2. During the recording process, the drive box 3 drives the main body of the live streaming device 4, the high-precision camera 6, and the holographic projector 7 to slide along a circular track spliced ​​together by multiple segmented tracks 2. Another set of drive boxes 3 drives the screen 10 to slide synchronously. The screen 10 is positioned relative to the high-precision camera 6 and the holographic projector 7, and can remain collinear during the sliding process. The holographic projector 7 can change the video background, which can be easily adjusted according to needs to meet the flexible recording requirements of live video recording. In this way, during the live video recording process, it is ensured that the real person is in the center of the recording screen, which improves the quality of subsequent digital human production and ensures the effect of the digital human in the subsequent interactive live streaming process. After the live video is recorded by the high-precision camera 6, the live video is imported into the main body of the live streaming device 4. Its built-in program converts the motion data of the live video into digital human animation, and it is visualized and previewed on the display screen 5. After the digital human video meets the conditions, it is input into the main body of the live streaming device 4. Finally, the encoder in the main body of the live streaming device 4 pushes the digital human video for live streaming and outputs the live stream. Combined with the hardware configuration, it supports the interaction between the digital human and the live streaming scene. Furthermore, by splicing the support rod 42 to the inside of the base frame 8 and the top frame 43, the support mechanism of the screen 10 can be quickly extended, assembled, and disassembled. Combined with the detachable base 35, it is easy to store after use. The rollers 36 in the two roll boxes 9, together with the turntable 37 and the limiting bolt 38, facilitate the winding and unwinding of the screen 10, making it easy to lay the screen 10 flat when in use and roll it up when not in use.
