Description

Technical Field

[0001] This utility model relates to the field of projection device technology, specifically to an immersive interactive ground projection device for digital exhibition halls. Background Technology

[0002] Projectors typically project computer-generated images onto the ground, while sensors can capture the visitor's position, movements, and trajectory in real time. The projected image is aligned with the sensor data to ensure that the user's actions match the projected content in real time. When a user steps on a certain area, the projection will trigger the corresponding animation.

[0003] The existing technology has the following problems:

[0004] The existing devices do not allow for adjustment of the projector's projection angle during use. If the exhibition hall floor is uneven or has a slope, a fixed angle may cause the projection area to deviate from the target position, failing to cover key interactive areas. A fixed projector angle will also cause the image to appear trapezoidal, especially when projecting onto an inclined floor or a non-vertical surface, where the edges of the image are stretched and distorted, destroying the immersive experience. In addition, the existing devices do not allow for the removal and replacement of the transparent protective cover of the projector head. After prolonged use, the transparent protective cover may accumulate dust, stains, or scratches, all of which will affect the transmittance and uniformity of the projected light, thereby reducing the clarity of the projected image, blurring details, and affecting the audience's immersive experience.

[0025] like Figure 2-3 As shown, this utility model provides a technical solution: Preferably, a motor 8 is fixedly connected to the upper side of the bracket 4, a first gear 9 is fixedly connected to the output shaft of the motor 8, a first rack 11 is meshed with the outer wall of the first gear 9, a movable block 10 is fixedly connected to the front side of the first rack 11, a second rack 12 is fixedly connected to the lower side of the movable block 10, a second gear 13 is meshed with the lower side of the second rack 12, a rotating shaft 14 is fixedly connected to the front side of the second gear 13, the outer wall of the rotating shaft 14 is rotatably connected to the fixed plate 5, the front end of the rotating shaft 14 is fixedly connected to the projector 6, fixed blocks 15 are fixedly connected to both the left and right sides of the projector 6, a limit block 17 is fixedly connected to the lower side of the bracket 4, a limit groove 16 is formed on the upper side of the movable block 10, and the outer wall of the limit block 17... Slidingly connected to the limiting groove 16, when the motor 8 is working, the output shaft of the motor 8 drives the first gear 9 to rotate. The first gear 9 meshes with the first rack 11, causing the first rack 11 to move linearly. The first rack 11 drives the movable block 10 to move, and the second rack 12 on the lower side of the movable block 10 also moves accordingly. The second rack 12 meshes with the second gear 13, and the second gear 13 rotates, thereby driving the rotating shaft 14, which is fixedly connected to the second gear 13, to rotate. Since the front end of the rotating shaft 14 is fixedly connected to the projector 6, the rotation of the projector 6 is realized, that is, the projection angle is adjusted. The cooperation between the limiting block 17 and the limiting groove 16 plays a limiting role in the movement of the movable block 10, ensuring that the movable block 10 moves on the predetermined track, making the projection angle adjustment more stable and precise.

[0026] like Figure 4-5As shown, this utility model provides a technical solution: Preferably, a transparent protective cover 19 is movably connected to the lower side of the projector 6. L-shaped locking blocks 20 are fixedly connected to both the left and right sides of the outer wall of the transparent protective cover 19. An opening 18 is provided on the lower side of the fixing block 15. The outer wall of the L-shaped locking block 20 is movably connected to the opening 18. A knob 21 is rotatably connected to the rear side of the L-shaped locking block 20. A worm gear 22 is fixedly connected to the front side of the knob 21. A worm wheel 23 is meshed with the outer wall of the worm gear 22. A threaded rod 24 is fixedly connected through the upper side of the worm wheel 23. A lifting block 25 is threadedly connected to the outer wall of the threaded rod 24. A slanted groove 26 is provided through the left side of the lifting block 25. A limit post 27 is slidably connected to the inner surface of the slanted groove 26. An insert block 28 is fixedly connected to the outer wall of the limit post 27. Slots 29 are provided on both the front and rear sides of the inner surface of the opening 18. The outer wall of the worm gear 22 is rotatably connected to the L-shaped locking block 20, and the outer wall of the insert block 28 is rotatably connected to the L-shaped locking block 20. The outer wall of the insert 28 is movably connected to the slot 29. When the transparent protective cover 19 needs to be removed, the knob 21 is turned, which drives the worm gear 22 to rotate. The worm gear 22 meshes with the worm wheel 23, causing the worm wheel 23 to rotate. The worm wheel 23 drives the threaded rod 24, which is fixedly connected through the worm gear, to rotate. Since the lifting block 25 is threadedly connected to the threaded rod 24, the lifting block 25 moves on the threaded rod 24. The inclined groove 26 on the left side of the lifting block 25 is slidably connected to the limiting post 27. As the lifting block 25 moves, the limiting post 27 drives the insert 28 to move, causing the insert 28 to be pulled out of the slot 29. At this time, the connection between the L-shaped locking block 20 and the opening 18 is released, so the transparent protective cover 19 can be easily removed. During installation, the above steps are reversed, and the insert 28 is inserted into the slot 29 to fix the transparent protective cover 19. This design allows the staff to easily clean the projector head and perform other operations, ensuring the quality of the projected image.

[0027] The working principle of this immersive interactive ground projection device in the digital exhibition hall will be explained in detail below.

[0028] like Figure 1-5As shown, when motor 8 is working, the output shaft of motor 8 drives the first gear 9 to rotate. The first gear 9 meshes with the first rack 11, causing the first rack 11 to move linearly. The first rack 11 drives the movable block 10 to move, and the second rack 12 on the lower side of the movable block 10 also moves accordingly. The second rack 12 meshes with the second gear 13, and the second gear 13 rotates, thereby driving the rotating shaft 14, which is fixedly connected to the second gear 13, to rotate. Since the front end of the rotating shaft 14 is fixedly connected to the projector 6, the rotation of the projector 6 is realized, that is, the projection angle is adjusted. The cooperation between the limiting block 17 and the limiting groove 16 plays a limiting role in the movement of the movable block 10, ensuring that the movable block 10 moves on the predetermined track, making the projection angle adjustment more stable and precise. When it is necessary to remove the transparent protective cover 19, turn the knob. 21. Knob 21 drives worm gear 22 to rotate, worm gear 22 meshes with worm wheel 23, causing worm wheel 23 to rotate. Worm wheel 23 drives threaded rod 24, which is fixedly connected through the worm gear, to rotate. Since lifting block 25 is threadedly connected to threaded rod 24, lifting block 25 moves on threaded rod 24. The inclined groove 26 on the left side of lifting block 25 is slidably connected to limiting post 27. As lifting block 25 moves, limiting post 27 drives insertion block 28 to move, causing insertion block 28 to be pulled out of slot 29. At this time, the connection between L-shaped locking block 20 and opening 18 is released, so transparent protective cover 19 can be easily removed. During installation, the above steps are reversed, and insertion block 28 is inserted into slot 29 to fix transparent protective cover 19. This design allows staff to easily clean the projector head and perform other operations, ensuring the quality of the projected image.

[0029] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
