[0001] The present invention relates to the technical field of projector fixing, and specifically, to a lifting device for conference room display and its control method. Background Art

[0002] A projector is a device that can project images or videos onto a screen. Projectors are widely used in places such as homes, offices, and schools. Projectors have advantages such as a large projection area, convenient storage, and easy use. When holding a meeting in a conference room, a projector is often used for projection. In an office, for the sake of convenient use, the projector is usually directly placed on the desktop.

[0003] However, when the existing projector is directly placed on the desktop, on the one hand, the projector and the connected wires will affect the usable area of the conference table and the aesthetics of the desktop. On the other hand, the projector is exposed on the desktop for a long time, which is prone to dust accumulation and even being scratched or bumped, making it inconvenient to use. Therefore, a lifting device that can drive the projector to lift and use is needed. Summary of the Invention

[0019] Embodiment 1

[0020] As Figures 1 to 7As shown in the figure, this embodiment proposes a conference room display lifting device, including a lifting bin 1, a protective groove 3 and a control panel 4. The lifting bin 1 is fixedly connected to the table body. The bottom of the lifting bin 1 is flush with the table body. A lifting mechanism is fixedly arranged in the lifting bin 1. A display adjustment mechanism is connected to the lifting mechanism. The lifting mechanism is used to drive the display adjustment mechanism to lift. A projector 2 is fixedly installed in the display adjustment mechanism. The display adjustment mechanism is used to store the projector 2 and drive the projector 2 to move. The protective groove 3 is opened at the top of the lifting bin 1. A top sealing mechanism is slidably arranged in the protective groove 3. The top sealing mechanism is connected to the display adjustment mechanism. The top sealing mechanism is used to protect the projector 2 when the projector 2 is in the lifting bin 1.

The control panel 4 is connected to the lifting mechanism and the display adjustment mechanism.

[0021] As Figures 1 to 4 shown, the lifting mechanism includes a driving cylinder 5, a fork arm lifting assembly 6 and a storage frame 7. The driving cylinder 5 is rotatably installed at the bottom of the lifting bin 1. The fork arm lifting assembly 6 is composed of a plurality of rotatably connected fork arms.

The fork arm lifting assembly 6 is a plurality of intersecting rotating support rods. One of the support rods is slidably connected to the lifting bin 1. When the support rod slides, it pushes the storage frame 7 upward. At the same time, it pushes the push frame 13 upward through the springs on the support feet 8. At this time, the projector 2 is below the push frame 13. When the push frame 13 pushes the push plate one 15 and the push plate two 16 to move, the items placed on the push plate one 15 and the push plate two 16 move along with the push plate one 15 and the push plate two 16. When the fork arm lifting assembly 6 pushes the storage frame 7 to rise, the springs push the push frame 13 upward.

[0022] As Figures 1 to 2 shown, the display adjustment mechanism includes a motor 9, a slide rail 10 and a mounting platform 11. The motor 9 is fixedly installed in the storage frame 7. The output end of the motor 9 is fixedly connected to a screw rod. The screw rod is rotatably connected to the storage frame 7. The slide rail 10 is fixedly connected to the storage frame 7. The mounting platform 11 is slidably connected to the slide rail 10. The mounting platform 11 is threadedly connected to the screw rod. The projector 2 is fixedly installed on the mounting platform 11. By driving the screw rod through the output end of the motor 9, the position of the mounting platform 11 sliding on the slide rail 10 can be adjusted, thereby adjusting the distance between the projector 2 and the screen, and then enhancing the projection effect. At the same time, when the mounting platform 11 slides, it can push the flap two 19 to rotate.

[0023] As Figures 1 to 2As shown, the installation platform 11 can slide on the slide rail 10 to the outside of the storage box 7. When the installation platform 11 slides away from the storage box 7, the installation platform 11 is above the top sealing mechanism.

[0024] As Figures 5 to 6 shown, the storage box 7 is provided with guiding rails 12. There are multiple guiding rails 12, and the multiple guiding rails 12 are arranged in a circle in the protective groove 3. The top sealing mechanism is slidably connected to the guiding rails 12. The positions where the support rods 14 are connected to the first push plate 15 and the second push plate 16 pass through the guiding rails 12, and the guiding rails 12 limit the sliding directions of the first push plate 15 and the second push plate 16.

[0025] As Figures 5 to 7 shown, the top sealing mechanism includes a pushing frame 13, support rods 14, a first push plate 15, a second push plate 16 and a flap assembly. The pushing frame 13 is sleeved on the storage box 7. The pushing frame 13 is connected to a spring. The top of the pushing frame 13 can contact the protective groove 3. There are four support rods 14, and the support rods 14 are rotatably connected to the pushing frame 13. There are two first push plates 15, and the two first push plates 15 are arranged oppositely. The first push plate 15 is slidably arranged in the guiding rail 12, and the first push plate 15 is rotatably connected to the support rod 14. There are two second push plates 16, and the two second push plates 16 are arranged oppositely. The second push plate 16 is slidably arranged in the guiding rail 12, and the second push plate 16 is rotatably connected to the support rod 14. The flap assembly is rotatably arranged on the first push plate 15 and the second push plate 16. The flap assembly is used to cover the projector 2 when the projector 2 descends. Before the pushing frame 13 pushes the first push plate 15 and the second push plate 16 to move away from each other, the first push plate 15 is staggered with the side of the second push plate 16. The first push plate 15, the second push plate 16, the first flap 17 and the second flap 19 can prevent dust and items from falling into the lifting bin 1. When the first push plate 15 and the second push plate 16 slide under the push of the pushing frame 13, they can drive the items thereon to move to avoid affecting the rising of the projector 2. Springs can be arranged on the first push plate 15 and the second push plate 16 to apply pressure to the first push plate 15 and the second push plate 16, so that they rotate in a direction parallel to the protective groove 3.

[0026] As Figures 4 to 7As shown in the figure, the flap assembly includes a first flap 17, a first support plate 18, a second flap 19 and a second support plate 20. There are multiple first flaps 17. The first push plate 15 is rotatably connected to the first flap 17. A first flap 17 is rotatably connected to the second push plate 16 away from the slide rail 10. There are multiple first support plates 18. The first support plates 18 are fixedly connected to the side of the storage frame 7 close to the first push plate 15. The first support plates 18 are in contact with the first flap 17. The second flap 19 is rotatably connected to the second push plate 16 close to the slide rail 10. The second support plates 20 are fixedly connected to the side of the storage frame 7 away from the slide rail 10. The second support plates 20 are rotatably connected to the second flap 19. The first flap 17 rotatably connected to the first push plate 15 is below the first flap 17 and the second flap 19 rotatably connected to the second flap 19. The second flap 19 is provided as a two-segment rotating plate. The first flap 17 on the second push plate 16 is located on the first flap 17 on the first push plate 15. The length of the first support plate 18 is also less than the length of the second support plate 20. The second support plate 20 first contacts the first flap 17 and pushes the first flap 17 to rotate. Then, the first support plate 18 contacts the other two first flaps 17 and pushes them to rotate. At this time, the storage frame 7 supports the second flap 19. Then, the installation platform 11 slides to push the second flap 19, so that the two segments of the plate on the second flap 19 rotate to the lower part of the installation platform 11 and will not block the lens of the projector 2.

[0027] In this embodiment, the control panel 4 is used to control the fork arm lifting assembly to drive the projector 2 to rise. During the rising process of the projector 2, the first push plate 15 and the second push plate 16 are first pushed to slide by the pushing frame 13. When the first push plate 15 and the second push plate 16 completely leave the top of the lifting bin 1, the spring is compressed. At this time, the storage frame 7 rises to push the first flap 17 and the second flap 19 to flip. At this time, the projector 2 rises above the desktop. The screw drives the installation platform 11 to move outwards to push the second flap 19 to flip. The projector 2 adjusts the distance from the screen under the drive of the installation platform 11. When the storage frame 7 descends, the spring elongates. The second flap 19 and the first flap 17 at the relative position of the second flap 19 first flip. Then, the other two first flaps 17 on the side flip and rotate above the second flap 19.

[0028] Embodiment 2 A conference room display lifting control method uses the above-mentioned conference room display lifting device, including the following steps: Step 1: Rise upwards: The control panel 4 is used to control the output end of the driving cylinder 5 to elongate to push the fork arm lifting assembly 6. The fork arm lifting assembly 6 pushes the storage frame 7 to move upwards. The spring on the support feet 8 pushes the pushing frame 13 to move upwards; Step 2: Open the push plates: The pushing frame 13 pushes the support rod 14 to move. The support rod 14 pushes the first push plate 15 and the second push plate 16 to slide on the guiding track 12. The first push plate 15 and the second push plate 16 drive the first flap 17 and the second flap 19 to move; Step 3. Flap rotation: The pushing frame 13 contacts the lifting bin 1, the spring is compressed and shortened, both the first support plate 18 and the second support plate 20 push the first flap 17 to turn upwards, and the storage frame 7 pushes the second flap 19 to rotate; Step 4. Display extension: The output end of the motor 9 drives the screw rod to rotate, the screw rod drives the installation platform 11 to slide on the slide rail 10, and the installation platform 11 pushes the second flap 19 to rotate.
