Description

Technical Field

[0001] The present invention relates to the technical field of display devices, and in particular to a multimedia intelligent hanging and lifting device. Background Art

[0002] A multimedia hall has multiple uses and can perform multiple tasks. In China, this term became popular in the 1980s. With the development of the economy and society, after the emergence of karaoke halls in society, there have been significant changes in architecture. When various units are constructing, they often convert conference halls into multi-functional halls, which also serve as lecture halls, academic discussion halls, training classrooms, as well as video conference halls, dance halls, etc. After reasonable layout, adding various functions as needed, installing corresponding equipment and taking corresponding technical measures, a multimedia hall can achieve the purpose of multiple functions, improve economic efficiency, and is widely welcomed. Then, larger projects follow, such as stadiums, theaters, and large halls designed with multi-functional architecture. Traditionally, the screen in a multimedia hall is usually hung on the wall facing the audience to display images to the audience. However, most of the screens in multimedia halls are installed on the wall in a fixed manner;

[0003] Therefore, in the prior art, a multimedia intelligent hanging and lifting device with the patent number CN202011145430.4 was proposed. When the motor of the curling drive assembly is started, the rope is wound around the winch, which requires the lower part of the frame body to move upward along the second guide rail with the aid of the roller mechanism. At the same time, the upper part of the frame body moves along the horizontally guided first guide rail through the roller mechanism. When the roller reaches the limit position in the first guide rail, the screen is in the storage position and can be used for stage performances. During the storage process of the screen, the screen itself will not be curled;

[0004] However, in the actual use process of this device, although the screen can be stored, in the actual use process, the screen can still only display its playing content in the middle of the multimedia hall and cannot adjust its display direction according to the viewing position of the viewer, resulting in the viewer having to look up and tilt for a long time to watch the screen, causing viewing fatigue and affecting the viewing experience of the viewer. Summary of the Invention

[0005] To solve the above technical problems, the present invention provides a multimedia intelligent hanging and lifting device to solve the problems described in the above background art.

[0012] As a further solution of the present invention: the front end of the push rod at the power output end of the electric push rod is connected to the upper part of the back surface of the connection disk, and the connection disk rotates 35° up and down around the shaft rod in the connecting piece.

[0013] As a further solution of the present invention: a gear disk is fixed at the front end of the transmission shaft at the power output end of the rotary motor, the gear disk on the rotary motor meshes with the teeth on the outer wall of the rear end of the connecting column, and the display rotates 90° clockwise and counterclockwise at the front end of the connection disk through the connecting column.

[0014] As a further solution of the present invention: the steps are divided into three layers: high, medium and low. Three seats are fixed in each layer of the steps. A high position sensor is separately fixed in each seat on the high layer of the steps, a medium position sensor is separately fixed in each seat on the middle layer of the steps, and a low position sensor is separately fixed in each seat on the low layer of the steps.

[0015] As a further solution of the present invention: the signal transmitting ends of the high position sensor, the medium position sensor and the low position sensor are independently connected to the signal receiving ends of the control panel in the control box through signal lines, and the signal receiving ends of the lifting motor, the servo motor, the electric push rod, the rotary motor and the multi-stage electric push rod are connected to the signal transmitting ends of the control panel in the control box through signal lines.

[0016] As a further solution of the present invention, it specifically further includes the following method:

[0017] S1: When the viewer sits on the seat on the left side of the low layer, the low position sensor on this seat sends information to the control panel in the control box.

[0021] S5: When the viewer sits on the seat in the middle of the middle layer, the middle-position sensor on the seat sends information to the control panel in the control box. After receiving the information, the control panel does not need to adjust the position of the display;

[0022] S6: When the viewer sits on the seat on the right side of the middle layer, the middle-position sensor on the seat sends information to the control panel in the control box. The control panel controls the multi-stage electric push rod to push the moving plate to slide to the right along the guide rod at the front end of the mounting plate through the push rod, adjusts the display position of the content played by the display, so that the display is exactly in front of the viewer;

[0023] S7: When the viewer sits on the seat on the left side of the upper layer, the high-position sensor on the seat sends information to the control panel in the control box. The control panel controls the multi-stage electric push rod to push the moving plate to slide to the left along the guide rod at the front end of the mounting plate through the push rod, adjusts the display position of the content played by the display, and at the same time, the lifting motor drives the lead screw to rotate counterclockwise inside the mounting plate, so that the mounting plate rises in the guide rail, and further adjusts the display height of the content played by the display, so that the display is exactly in front of the viewer;

[0024] S8: When the viewer sits on the seat in the middle of the upper layer, the high-position sensor on the seat sends information to the control panel in the control box. The control panel controls the lifting motor to drive the lead screw to rotate counterclockwise inside the mounting plate, so that the mounting plate rises in the guide rail, and further adjusts the display height of the content played by the display, so that the display is exactly in front of the viewer;

[0025] S9: When the viewer is sitting on the seat on the left side of the upper floor, the high-position sensor on the seat sends information to the control panel in the control box. The control panel controls the multi-stage electric push rod to push the moving plate along the guide rod at the front end of the mounting plate to slide to the right through the push rod, adjusting the display position of the content played by the display. At the same time, the lifting motor drives the lead screw to rotate counterclockwise inside the mounting plate, causing the mounting plate to rise in the guide rail, thereby adjusting the display height of the content played by the display, so that the display is exactly in front of the viewer;

[0026] S10: When the display is exactly in front of the viewer, the control panel in the control box can be manually operated to make the electric push rod rotate up and down at the front end of the connecting piece by pushing or pulling the connecting disc, so that the connecting disc 411 and the display at its front end pitch up and down, adjusting the display angle of the content played by the display 5. It can also make the servo motor drive components such as the transmission rod, the rotating plate, the connecting disc and the display to rotate left and right in the clockwise and counterclockwise directions through the gear disc, adjusting the display direction of the content played by the display. It can also make the rotating motor drive the connecting column to rotate through the gear disc, and the connecting column drives the display connected to one end to rotate 90°, making the display set vertically, so that the display can be switched horizontally and vertically according to the actual situation.

[0027] The present invention provides a multimedia intelligent hanging and lifting device, which has the following beneficial effects:

Detailed implementation manners

[0039] Embodiment 1, please refer to Figure 1-8 , a multimedia intelligent hanging and lifting device, comprising a multimedia room 1, a control box 2 and steps 3. A control box 2 is fixedly installed on the upper right side of the upper surface of the multimedia room 1, steps 3 are fixedly installed at the front end of the multimedia room 1, seats 301 are installed on the steps 3 from high to low, high position sensors 302, middle position sensors 303 and low position sensors 304 are respectively fixedly installed inside the seats 301 from high to low, guide rails 4 are vertically fixedly installed on both the left and right sides at the rear end of the multimedia room 1, and a multimedia lifting assembly is arranged at the front end between the two guide rails 4.

[0040] The multimedia lifting assembly is composed of a mounting plate 401, a guide rod 402, a lifting motor 403, a lead screw 404, a moving plate 405, a servo motor 406, a transmission rod 407, a rotating plate 408, an electric push rod 409, a connecting piece 410, a connecting disk 411, a rotating motor 412, a connecting column 413 and a multi-stage electric push rod 414;

[0041] An installation plate 401 is embedded between two guide rails 4. Guide rods 402 are horizontally fixed at both the upper and lower ends of the front surface of the installation plate 401. A lifting motor 403 is fixed to the top of the multimedia room 1. A lead screw 404 is fixedly connected to the bottom of the transmission shaft at the power output end of the lifting motor 403. A moving plate 405 is nested outside the two guide rods 402. A servo motor 406 is fixed in the middle of the front surface of the moving plate 405. A transmission rod 407 is vertically fixed at the front end of the middle of the moving plate 405. A rotating plate 408 is fixed to the front end of the transmission rod 407. An electric push rod 409 is fixed above the middle of the rotating plate 408. Connecting pieces 410 are fixed on both the left and right sides at the front end of the rotating plate 408. The front end of the connecting piece 410 is connected to a connecting disk 411 through a shaft rod. A rotating motor 412 is fixed to the lower part at the rear end of the connecting disk 411 through a bracket. A connecting column 413 is embedded in the middle of the connecting disk 411. A multi-stage electric push rod 414 is fixed above the right side of the installation plate 401. A display 5 is fixed to the front end of the connecting column 413;

[0042] Limit holes are horizontally opened at both the upper and lower ends inside the moving plate 405. The guide rods 402 are exactly embedded in the limit holes. The vertical cutting area of the guide rods 402 is the same as the vertical cutting area of the limit holes. The left side of the push rod at the power output end of the multi-stage electric push rod 414 is connected to the moving plate 405. The moving plate 405 slides horizontally left and right along the outer wall of the guide rod 402;

[0043] During the operation of the multi-stage electric push rod 414, the multi-stage electric push rod 414 pushes or pulls the moving plate 405 to slide left and right along the guide rod 402 at the front end of the installation plate 401, so that several components such as the moving plate 405, the rotating plate 408, the connecting disk 411, and the display 5 slide left and right at the same time, adjusting the display position of the content played by the display 5 so that the display 5 is exactly in front of the viewer;

[0044] The steps 3 and the seats 301 in the middle of the steps 3 are exactly in the middle front of the display 5. The lead screw 404 is exactly vertically embedded in the middle of the installation plate 401. The outer wall of the lead screw 404 is connected to the inner wall of the installation plate 401 through a thread. The installation plate 401 moves up and down vertically along the guide rail 4;

[0045] During the operation of the lifting motor 403, by driving the lead screw 404 to rotate clockwise or counterclockwise in the installation plate 401, the installation plate 401 moves up and down in the guide rail 4, so that several components such as the moving plate 405, the rotating plate 408, the connecting disk 411, and the display 5 at the front end of the installation plate 401 move up and down at the same time, adjusting the display height of the content played by the display 5;

[0046] At the bottom of the transmission shaft at the power output end of the servo motor 406, a gear disc is fixed. The teeth on the outer wall of the gear disc are meshed with the teeth on the outer wall of the transmission rod 407. The gear disc drives the transmission rod 407 to rotate 35° left and right at the front end of the moving plate 405;

[0047] When the servo motor 406 is working, by driving the gear disc to rotate clockwise or counterclockwise, the gear disc can drive several components such as the transmission rod 407, the rotating plate 408, the connecting disc 411, and the display 5 to rotate left and right clockwise and counterclockwise, adjusting the display direction of the content played by the display 5 so that the middle part of the display 5 is exactly facing the viewer;

[0048] The front end of the push rod at the power output end of the electric push rod 409 is connected to the upper part of the back surface of the connecting disc 411. The connecting disc 411 rotates 35° up and down around the shaft rod in the connecting piece 410;

[0049] When the electric push rod 409 is working, by pushing or pulling the connecting disc 411 to rotate up and down at the front end of the connecting piece 410, the connecting disc 411 and the display 5 at its front end can be pitched up and down, adjusting the display angle of the content played by the display 5 so that the viewer does not have to look up and down at the display 5 for a long time, further improving the viewing experience of the viewer.

[0050] Example 2, please refer to Figure 1-8 , the difference between Example 2 and Example 1 is that a gear disc is fixed at the front end of the transmission shaft at the power output end of the rotating motor 412. The gear disc on the rotating motor 412 is meshed with the teeth on the outer wall of the rear end of the connecting column 413. The display 5 rotates 90° clockwise and counterclockwise at the front end of the connecting disc 411 through the connecting column 413;

[0051] During the process that the rotating motor 412 drives the connecting column 413 to rotate through the gear disc, the connecting column 413 will simultaneously drive the display 5 connected to one end to rotate 90°, so that the display 5 is vertically arranged, and then the display 5 can be switched horizontally and vertically according to the actual situation, with high flexibility, further improving the viewing experience of the viewer.

[0052] Example 3, please refer to Figure 1-8 , the difference between Example 3 and Example 2 is that the step 3 is divided into three layers: high, medium, and low. Three seats 301 are fixed in each layer of the step 3. A high position sensor 302 is separately fixed in each seat 301 on the high layer of the step 3. A middle position sensor 303 is separately fixed in each seat 301 on the middle layer of the step 3. A low position sensor 304 is separately fixed in each seat 301 on the low layer of the step 3;

[0053] The signal transmitting ends of the high-position sensor 302, the middle-position sensor 303, and the low-position sensor 304 are independently signal-connected to the signal receiving ends of the control panel in the control box 2 through signal lines. The signal receiving ends of the lifting motor 403, the servo motor 406, the electric push rod 409, the rotating motor 412, and the multi-stage electric push rod 414 are signal-connected to the signal transmitting ends of the control panel in the control box 2 through signal lines;

[0054] Since each of the three layers of steps 3, namely the high, middle, and low layers, is provided with three seats 301, and each seat 301 is provided with an independent high-position sensor 302, middle-position sensor 303, and low-position sensor 304. When a viewer sits on the seat 301, the corresponding high-position sensor 302, middle-position sensor 303, or low-position sensor 304 of the seat 301 will promptly send information to the control panel in the control box 2. Then, the control panel will adjust the height, pitch angle, left and right orientations, left and right positions, and portrait / landscape orientation of the display 5 according to the actual situation;

[0055] When only the seats 301 on the lowermost step 3 or only the seats 301 on the uppermost step 3 are occupied by viewers, the low-position sensor 304 in the lowermost step 3 or the high-position sensor 302 in the high-position sensor 302 sends information to the control panel, causing the control panel to turn on the lifting motor 403 to drive the lead screw 404 to rotate clockwise or counterclockwise in the mounting plate 401, enabling the mounting plate 401 to move up and down in the guide rail 4. As a result, several components such as the moving plate 405, the rotating plate 408, the connecting disk 411, and the display 5 at the front end of the mounting plate 401 move up and down simultaneously, adjusting the display height of the content played by the display 5. At the same time, the electric push rod 409 can push or pull the connecting disk 411 to rotate up and down at the front end of the connecting piece 410, enabling the connecting disk 411 and the display 5 at its front end to pitch up and down, adjusting the display angle of the content played by the display 5, so that the viewer does not have to look up and down at the display 5 for a long time;

[0056] When only the seat 301 on the leftmost or rightmost side of the step 3 is occupied by a viewer, the multi-stage electric push rod 414 pushes or pulls the moving plate 405 to slide left and right along the guide rod 402 at the front end of the mounting plate 401 through the push rod, causing several components such as the moving plate 405, the rotating plate 408, the connecting disk 411, and the display 5 to slide left and right simultaneously, adjusting the display position of the content played by the display 5 so that the display 5 is exactly in front of the viewer. At the same time, the servo motor 406 can drive the gear disk to rotate clockwise or counterclockwise, causing the gear disk to drive several components such as the transmission rod 407, the rotating plate 408, the connecting disk 411, and the display 5 to rotate left and right clockwise and counterclockwise, adjusting the display direction of the content played by the display 5 so that the middle of the display 5 is exactly facing the viewer.

[0057] Example 4. Please refer to Figure 1-8 . The difference between Example 3 and Example 2 is that the following method is further included specifically:

[0058] S1: When the viewer sits on the seat 301 on the left side of the lower layer, the low-position sensor 304 on the seat 301 sends information to the control panel in the control box 2.
