Description

Technical Field

[0001] This utility model relates to the field of motion-sensing interactive device technology, and in particular to a large-scale three-dimensional spatial light field display system. Background Technology

[0002] In recent years, with the popularization and development of multimedia technology, people have been exploring new human-computer interaction technologies. Convenient, advanced and reliable human-computer interaction systems have emerged through various high-tech means. Many best-selling electronic products have also generated huge economic benefits due to excellent human-computer interaction methods. Controlling LED displays through gesture recognition modules is dynamic and novel, with a strong sense of technological experience and interactive fun. The technology is relatively mature and widely used.

[0003] Existing technology publication number CN216817350U discloses a "Gesture Recognition Light Ring Digital Interactive Device," comprising: a gesture sensor; a distance sensor disposed in the middle of the inner wall of the gesture sensor; heat dissipation holes, a plurality of which are respectively formed in a circumferential direction on the outer wall of the gesture sensor; a base fixedly mounted on the bottom end of the gesture sensor; a camera disposed at the top center of the base, with its shooting angle at the inner center of the gesture sensor; a connecting seat fixedly disposed at the bottom end of the gesture sensor; and a locking component disposed at the bottom end of the connecting seat. This gesture recognition light ring digital interactive device employs the latest motion-sensing control technology. Viewers only need to extend one hand into the light ring and make various waving gestures to control the screen to view images and videos, providing a powerful technological experience and interactive fun.

[0004] However, the aforementioned existing technologies still have certain shortcomings in use: First, the existing technologies include a locking component between the gesture sensor and the connector, which allows the gesture sensor to be adjusted at any angle to accommodate users of different heights. However, simply adjusting the angle cannot adapt to people of different heights, such as children and adults, whose heights differ significantly. Adjusting the angle alone only provides limited height adjustment and cannot adequately meet the needs of users of all heights. Second, in real life, the best experience is when the motion-sensing interactive device is directly in front of the display screen. When a user is explaining the interactive device to another user, it is best placed to the side of the display screen. Furthermore, the position of the motion-sensing interactive device may vary depending on the installation location of the display screen. However, the existing motion-sensing interactive device has a base at the bottom, meaning that it can only be moved by lifting the entire device, which is inconvenient and increases the workload for staff. Therefore, further improvements are needed. Utility Model Content

The vertical section of the L-shaped connector 19 is adapted to the vertical section of the L-shaped sliding groove 20. Several casters 21 are respectively set on the bottom surface of the vertical section of all the L-shaped connectors 19. It should be noted that the number of L-shaped connectors 19 and L-shaped sliding grooves 20 can be adjusted according to the requirements.

[0035] Please see Figure 4-6 A drive assembly 22 is provided on one side of the limiting post 2. By changing the drive assembly 22, the height adjustment assembly 3 and the moving assembly 14 can be driven respectively. The drive assembly 22 includes a motor 32 and a plate 28. A cylindrical groove 5 23 is opened on the top surface of the base 1. The cylindrical groove 5 23 is located between two L-shaped sliding grooves 20 and communicates with the cylindrical groove 4 15. A tube 24 with the inner diameter of the cylindrical groove 5 23 is fixedly installed at the top of the cylindrical groove 5 23. The tube 24 communicates with the limiting post 2. There is a notch 25 communicating with the cylindrical groove 11. The top surface of the tube body 24 is symmetrically provided with a sliding groove 26. The side of the tube body 24 away from the limiting post 2 is provided with a sliding groove 27. Rectangular strips 29 are symmetrically fixed on both sides of the plate 28. The rectangular strips 29 on both sides are slidably disposed in the sliding grooves 26 on both sides. The plate 28 is located inside the tube body 24. The top surface of the base 1 is symmetrically fixed with sliding posts 31. The sliding posts 31 on both sides pass through and are slidably disposed in the rectangular strips 29 on the corresponding sides. The plate 2 A rectangular strip 20 is fixedly installed on one side of plate 28. The rectangular strip 20 is slidably installed in the slide groove 27. The motor 32 is fixedly installed on the top surface of plate 28. The output shaft of the motor 32 passes through and rotates on the top surface of plate 28. A rotating rod 33 is fixedly installed at the top of the output end of the motor 32. A gear 34 is fixedly installed coaxially at the upper end of the rotating rod 33. A gear 4 35 is fixedly installed coaxially at the bottom end of the rotating rod 33. Gear 34 can mesh with gear 12 for transmission. Gear 4 35 can mesh with gear 12 for transmission. The gear 16 meshes with the gear 34, and the gear 16 and gear 4 are in a disengaged state. When the gear 12 and gear 34 mesh, the gear 12 and gear 34 are in a disengaged state. The top surface of the base 1 has a slot 36, which is connected to the cylindrical slot 4 15 and is located directly below the rectangular bar 2 30. An electric telescopic rod 37 is fixedly installed on the bottom surface of the slot 36, and the moving end of the electric telescopic rod 37 is fixedly connected to the bottom surface of the rectangular bar 2 30.

[0036] When the device needs height adjustment, motor 32 is first started, causing it to slowly rotate gears 34 and 35 via rotating rod 33. Then, electric telescopic rod 37 extends, pushing rectangular bar 2 30 upwards. Rectangular bar 2 30 then moves plate 28, rectangular bar 29, motor 32, gears 34 and 35, and rotating rod 33 upwards together. The slowly rotating gear 34 gradually meshes with gear 1 12. After gear 34 meshes with gear 12, gear 45 simultaneously separates from gear 216. Gear 34 drives gear 12 to rotate, which in turn drives lead screw 13 to rotate, thereby causing the moving column 5 to move vertically along the cylindrical groove 4. This allows for height adjustment of the annular part 7 at the top of the moving column 5, making it suitable for users of different heights. It should be noted that the meshing of gear 34 and gear 12 is the initial state. When height adjustment is needed, motor 32 can be directly started for forward and reverse rotation.

[0037] When the device needs to be moved, the electric telescopic rod 37 is retracted, causing the moving end of the electric telescopic rod 37 to move and descend along with the rectangular bar 30. This causes gears 34 and 45 to begin descending. During the descent, gear 34 gradually disengages from gear 12, and gear 45 gradually engages with gear 26. It is important to note that during the descent, the motor 32 continues to drive the gears to rotate slowly so that the disengaged gears can mesh with each other. Once gear 45 engages with gear 26, gear 45 drives gear 26 to rotate, and the rotation of gear 26 drives the plate. 28 and L-shaped connector 19 move downward along L-shaped sliding groove 20, thereby causing the universal wheel 21 at the lower outer end of L-shaped connector 19 to gradually extend out of base 1 and support the entire device. After the universal wheel 21 extends, the entire device can be pulled to move to any position. When the device moves to the desired position, the motor 32 is started in the opposite direction, thereby causing the universal wheel 21 to retract into base 1, so that the bottom surface of base 1 can serve as the support surface. Then the electric telescopic rod 37 is started again, so that gear 34 meshes with gear 12, so that the ring part 7 can be adjusted in height.

[0038] Based on the above description in this specification, those skilled in the art will also understand that the following terms, such as "upper," "lower," "front," "rear," "left," "right," "inner," and "outer," which indicate orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings of this specification.
