[0030] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0031] This utility model provides, for example Figures 1-6 The suspended multimedia interactive projection screen shown includes a mounting box 1, a wall 16 on the outside of the mounting box 1, a storage groove 17 on the inside of the wall 16, a drive cylinder 18 fixedly installed inside the storage groove 17, and the output end of the drive cylinder 18 fixedly connected to the mounting box 1; the mounting box 1 matches the storage groove 17; a rotatably connected take-up roller 7 is provided inside the mounting box 1, and an interactive projection screen 8 is provided on the outside of the take-up roller 7.

[0032] Specifically, after projection is completed, the interactive projection screen 8 of this invention can be rotated by the take-up roller 7 to retract the interactive projection screen 8 to the outside of the take-up roller 7. Then, the drive cylinder 18, which is fixedly installed inside the wall 16, is activated. Because the output end of the drive cylinder 18 is fixedly connected to the mounting box 1, and the mounting box 1 matches the storage groove 17 opened inside the wall 16, it can drive the mounting box 1 to retract into the wall 16. When not in use, the interactive projection screen 8 of this invention can be retracted to the outside of the take-up roller 7 inside the mounting box 1, and the mounting box 1 can be stored inside the wall 16, improving the overall aesthetics.

[0033] Reference Figure 6 A sliding plate 19 is fixedly connected to the outer wall of the mounting box 1, and a guide groove 20 is provided on the inner side of the wall 16. The sliding plate 19 is slidably connected to the guide groove 20.

[0034] As the output end of the drive cylinder 18 moves the mounting box 1, the sliding plate 19 fixedly connected to the outer wall of the mounting box 1 will slide within the guide groove 20 opened on the inner side of the mounting box 1, thereby improving the stability of the mounting box 1 when it moves.

[0035] Reference Figures 2-3 The first motor 2 is fixedly installed inside the mounting box 1. The output end of the first motor 2 is fixedly connected to the first spur gear 3. One end of the take-up roller 7 is fixedly connected to the second spur gear 4. The first spur gear 3 and the second spur gear 4 mesh with each other.

[0036] The output of the first motor 2 can drive the first spur gear 3 to rotate. Since the first spur gear 3 meshes with the second spur gear 4, it can drive the second spur gear 4 and the take-up roller 7 to rotate, thereby enabling the interactive projection screen 8 to be rolled up to the outside of the take-up roller 7.

[0037] Reference Figure 3 and Figure 5 The mounting box 1 is fixedly connected to the mounting base 5, and the mounting base 5 is fixedly installed with the bearing 6. The winding roller 7 is rotatably connected to the bearing 6.

[0038] When the take-up roller 7 is powered, it will rotate inside the bearing 6. The bearing 6 can improve the rotation effect of the take-up roller 7. In addition, the mounting base 5 supports the bearing 6, so that the take-up roller 7 can rotate stably inside the bearing 6 and perform the take-up operation on the interactive projection screen 8.

[0039] Reference Figure 3 and Figure 5 The two sides of the take-up roller 7 are fixedly connected to the limiting disks 9, and the interactive projection screen 8 is located between the two limiting disks 9.

[0040] By setting two limiting discs 9 on the outside of the interactive projection screen 8, the two limiting discs 9 can limit the winding of the interactive projection screen 8, thereby improving the winding effect of the interactive projection screen 8.

[0041] Reference Figures 4-5 The second motor 10 is fixedly installed inside the mounting box 1. The output end of the second motor 10 is fixedly connected to the third spur gear 11. The outer side of the third spur gear 11 is meshed with a rack 12. The outer side of the rack 12 is fixedly connected to a movable seat 13. The outer wall of the movable seat 13 is fixedly connected to a limit plate 15.

[0042] The output of the second motor 10 can drive the third spur gear 11 to rotate. Because the third spur gear 11 meshes with the rack 12, it can drive the rack 12 to slide. Furthermore, because a movable seat 13 is fixedly connected to the outer side of the rack 12, and a limiting plate 15 is fixedly connected to the outer wall of the movable seat 13, the limiting plate 15 can be driven to move towards the interactive projection screen 8 and limit the end of the interactive projection screen 8 in the winding state, thereby improving the winding effect of the interactive projection screen 8.

[0043] Reference Figures 4-5 The interior of the mounting box 1 is fixedly connected with a guide rod 14, and the movable seat 13 is slidably connected to the guide rod 14.

[0044] During the movement of the rack 12, the movable seat 13 fixedly connected to the bottom of the rack 12 will slide on the outside of the guide rod 14, thereby improving the stability of the movable seat 13 and the limiting plate 15 during movement.

[0045] Working principle:

[0046] After projection is completed, the interactive projection screen 8 of this invention can be retracted by the take-up roller 7, which rotates and retracts the interactive projection screen 8 to the outside of the take-up roller 7. Then, the drive cylinder 18, which is fixedly installed inside the wall 16, is activated. Because the output end of the drive cylinder 18 is fixedly connected to the mounting box 1, and the mounting box 1 matches the storage groove 17 opened inside the wall 16, it can drive the mounting box 1 to retract into the wall 16. When not in use, the interactive projection screen 8 of this invention can be retracted to the outside of the take-up roller 7 inside the mounting box 1, and the mounting box 1 can be stored inside the wall 16, improving the overall aesthetics.

[0047] When the interactive projection screen 8 is being wound up, the first motor 2 can be activated. The output of the first motor 2 can drive the first spur gear 3 to rotate. Since the first spur gear 3 meshes with the second spur gear 4, it can drive the second spur gear 4 and the winding roller 7 to rotate, thereby winding the interactive projection screen 8 to the outside of the winding roller 7. Then, the output of the second motor 10 can drive the third spur gear 11 to rotate. Since the third spur gear 11 meshes with the rack 12, it can drive the rack 12 to slide outside the guide rod 14. Furthermore, since the outer side of the rack 12 is fixedly connected to the movable seat 13, and the outer wall of the movable seat 13 is fixedly connected to the limiting plate 15, it can drive the limiting plate 15 to move towards the interactive projection screen 8 and limit the end of the interactive projection screen 8 in the winding state, thereby improving the winding effect of the interactive projection screen 8.

[0048] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
