Description

Technical Field

[0001] The present invention relates to the technical field of immersive interactive VR display devices, and in particular to a digital twin virtual immersive interactive VR display device. Background Art

[0002] Combining digital twins with VR technology can create a more realistic and interactive virtual environment, allowing users to "enter" the digital twin to observe and operate. This requires not only accurate modeling of physical objects, but also efficient data processing and real-time interaction capabilities. In addition, with the popularization of 5G networks, low-latency, high-bandwidth network conditions have made it possible for such systems that rely heavily on data transmission, further promoting the development of digital twin virtual immersive interactive VR display devices. When using a flexible screen that is easy to retract as an interactive VR display device, after the flexible screen is rolled up on a roller, the lower side of the flexible screen cannot be properly limited to ensure that the rolled-up display screen remains perpendicular to the ground, thus affecting the projection effect of the flexible screen. Summary of the Invention

[0024] The following is combined with Figure 1-8 The present invention is further described with examples:

[0025] A digital twin virtual immersive interactive VR display device includes a base 1, two support plates 2 are fixedly provided on both sides of the base 1, a top plate 3 is fixedly provided above the two support plates 2, a driving member 4 is fixedly provided on one of the support plates 2, the output shaft of the driving member 4 can rotatably pass through the support plate 2 adjacent to the driving member 4 and is fixedly connected to a rotating shaft 5, the other end of the rotating shaft 5 is rotatably connected to the other support plate 2, a flexible screen 100 is connected to the rotating shaft 5, a positioning rod 6 is fixedly provided at the lower end of the flexible screen 100, a slide rail 7 is fixedly provided on the base 1, and two reciprocating positioning components are provided on the slide rail 7. When the positioning rod 6 cooperates with the positioning component, the lower end of the flexible screen 100 can be limited.

[0026] The positioning assembly includes a slider 20 that reciprocates within the slide rail 7. A positioning sleeve 21 is fixedly mounted on the slider 20. The positioning sleeve 21 defines a positioning through-hole 22. Multiple retaining members are evenly distributed along the circumference of the positioning sleeve 21. In this embodiment, the diameter of the positioning through-hole 22 is 1 mm larger than the diameter of the positioning rod 6. This ensures that the positioning rod 6 does not wobble once inserted into the positioning through-hole, while also making it easier to remove the positioning rod 6 once it is within the positioning through-hole 22.

[0027] Each locking member includes a groove 30 arranged on the end face of the positioning sleeve 21 close to the positioning rod 6, a reciprocating abutment rod 31 is arranged in the groove 30, a rotating shaft 32 is rotatably arranged on the inner wall of the groove 30, a flip plate 33 is fixedly arranged on the rotating shaft 32, and a flip abutment head 34 is fixedly arranged on the flip plate 33.

[0028] A transmission assembly is provided between the push rod 31 and the flip plate 33, and the transmission assembly includes a transmission cavity 310 arranged on the inner wall of the groove 30, and a reciprocating rack 320 is provided in the transmission cavity 310. The rack 320 is fixedly connected to the push rod 31, and a gear 330 meshing with the rack 320 is fixedly provided on the rotating shaft 32.

[0029] A trapezoidal groove 40 is provided on the inner wall of the transmission cavity 310 , a trapezoidal block 41 is fixedly provided on the rack 320 , and the trapezoidal block 41 can reciprocate in the trapezoidal groove 40 , and a return spring 42 is fixedly provided between the trapezoidal block 41 and the inner wall of the trapezoidal groove 40 .

[0030] The cross section of the slide rail 7 is trapezoidal (the cross section is the cross section perpendicular to the length direction of the slide rail 7 ), and the cross section of the slider 20 is trapezoidal (the cross section is the shape seen when cut perpendicular to the movement direction of the slider).

[0031] In this embodiment, the driving member 4 is an electric motor.

[0032] Working principle: the driving part 4 is started, driving the rotating shaft 5 to rotate, and the flexible screen 100 rolled up on the rotating shaft 5 is unfolded downward through the self-rotation of the rotating shaft 5. When the flexible screen 100 moves downward to the extreme position with the positioning rod 6, the positioning rod 6 is allowed to come between the two positioning sleeves 21 (that is, the positioning rod 6 is located between the two positioning through-holes 22), and then the slider 20 is pushed along the length direction of the slide rail 7 to move toward the positioning rod 6. At the same time, the positioning rod 6 is held to allow the positioning rod 6 to enter the positioning through-hole 22. When the flexible screen 100 is not completely perpendicular to the ground, but is slightly deflected, the axis center line of the positioning rod 6 and the axis center line of the positioning through-hole 22 will not be in the same straight line, making the positioning rod 6 unable to enter the positioning through-hole 22. At this time, the positioning rod 6 will conflict with the resistance around the positioning through-hole 22. The lever 31 is pushed into the groove 30, and the lever 31 moves with the rack 320, and the rack 320 rotates with the gear 330, so that the gear 330 rotates with the rotating shaft 32, the flip plate 33 and the flip butt 34, and the flip butt 34 rotates in the direction close to the axis of the positioning sleeve 22, thereby pushing the positioning rod 6 toward the axis of the positioning through hole 22, so that the axis of the positioning rod 6 can be aligning with the axis of the positioning through hole 22, thereby facilitating the insertion of the positioning rod 6 into the positioning through hole 22. By providing the retaining members on both sides and in the upper and lower directions of the positioning through hole 22, the positioning rod 6 that deviates from the axis of the positioning through hole 22 can be corrected more smoothly, thereby facilitating the insertion of the positioning rod 6 into the positioning through hole 22.
