Description

Technical Field

[0001] The present invention relates to the technical field of smart podiums, and in particular to an adjustable smart podium that can stop when encountering an obstacle. Background Art

[0002] A smart podium is a product that integrates a podium with electronic products such as computers, multimedia control systems, video booths, audio equipment, audio and video converters, etc. It has the characteristics of considerate humanized design, precise intelligent control, network anti-theft security design, large-capacity internal space, and multiple uses. With the development of intelligence, the use of smart podiums is becoming more and more widespread. In many places nowadays, smart podiums are used in teaching students. Since most of the existing smart podiums have a simple structure, these electronic facilities such as display screens are usually fixed on the podium, which makes it impossible to adjust the angle according to people's height, usage habits, usage occasions and other different needs.

[0003] Among them, the Chinese patent document with application number CN202220117366.7, a smart podium, includes: a shell, an operating table arranged above the shell, a computer host arranged in the shell, and a display screen connected to the computer host and arranged in the operating table, and also includes: a lifting device, the lifting device connects the shell and the operating table, the operating table has a protective cover, the protective cover is located on the bottom surface of the operating table and extends downward, the protective cover is arranged on the outside of the shell, a telescopic cover is arranged between the top surface of the shell and the bottom surface of the operating table, the telescopic cover and the protective cover enclose the lifting device to shield the lifting device.

[0004] However, there are still some problems during use. When the table top is lowered, it may hit a higher obstacle on the outside, causing the entire smart podium to tip over and damage the lifting components. The status of the table top cannot be identified in time. At the same time, it is more troublesome to inspect the internal host. The staff needs to squat and reach into the podium to disassemble the host. In this process, the table top is more protruding and may hit the staff's head. When the smart podium is moved, the protruding table top will cause the cross-section of the smart podium to widen, resulting in greater limitations on the movement of the device.

[0005] Therefore, the present invention provides an adjustable smart podium that can stop when encountering obstacles to solve the above problems. Summary of the invention

The bottom of the rectangular tube 201 can always be connected to the outside through the two circular holes. A piston plate 207 is provided at the bottom of the vertical rod 206, and the piston plate 207 cooperates with the inner wall of the rectangular tube 201, and the piston plate 207 is slidably connected to the inner wall of the rectangular tube 201, and a rubber ring (not shown in the figure) is provided on the outer ring of the piston plate 207 to ensure the air tightness between the piston plate 207 and the rectangular tube 201. An electric telescopic rod 208 is provided at the bottom of the piston plate 207, and the bottom of the electric telescopic rod 208 is connected to the top of the cabinet 109. The piston plate 207 can be adjusted by the extension and contraction of the electric telescopic rod 208. The movement of the piston plate 207 is actively controlled. When the piston plate 207 moves upward, it squeezes the gas between the top of the piston plate 207 and the rectangular tube 201. Conversely, negative pressure is generated between the top of the piston plate 207 and the rectangular tube 201. A solenoid valve 209 is provided on the right side of the top of the rectangular tube 201. The outer side of the solenoid valve 209 is connected to the high-pressure hose 202. By controlling the opening and closing state of the solenoid valve 209, the connection between the solenoid valve 209 and the high-pressure hose 202 is switched, and the front end of the table 104 is Two electric push rods 203 are provided, and the two electric push rods 203 are arranged symmetrically with the rectangular tube 201 as the symmetry axis. The bottom of the electric push rod 203 is connected to the top of the cabinet 109. When the vertical rod 206 and the two electric push rods 203 are raised and lowered at the same time, the table top 104 can be driven to rise and fall as a whole. When the vertical rod 206 rises and the two electric push rods 203 shrink, the rear end of the table top 104 will tilt upward, otherwise the rear end of the table top 104 will rotate downward to reach a tilted state.

[0043] The left and right ends of the cylindrical rod 307 are provided with coil springs 308, and the other ends of the two coil springs 308 are connected to the cabinet 109.

The rotation of the motor 301 drives the fixedly connected worm 302 to rotate, and the worm 302 drives the meshed worm wheel 303 to rotate, thereby realizing the rotation control of the first winding roller 304, and because the worm wheel 303 and the worm 302 have self-locking characteristics, when the motor 301 does not rotate, the first winding roller 304 will not rotate on its own.

[0044] The maintenance component includes two guide rails 406, and the two guide rails 406 are arranged symmetrically with the limit block 403 as the symmetry axis. The bottom of the guide rail 406 is fixedly connected to the bottom of the cabinet 109, and the guide rail 406 is tilted upward as a whole.

A cup holder 106 is provided at the rear right side of the table top 104, and the cup holder 106 can be used to place water cups.

[0048] When in use, the state of the table top 104 can be controlled separately according to different usage scenarios. When a speech is needed, the electric telescopic rod 208 is controlled to move upward synchronously with the electric push rod 203, thereby driving the table top 104 to move horizontally upward. When the table top 104 is about to move to the highest point, the electric push rod 203 is controlled to increase the moving speed, and there is a distance difference with the movement of the electric telescopic rod 208, so that the front end of the table top 104 moves upward a greater distance, thereby realizing that the front end of the table top 104 is slightly moved upward during the upward movement. The table top 104 is tilted upward, which is convenient for the speaker to support the desktop with his hands and to see the speech on the table top 104 more conveniently. In the process of the table top 104 rising, the second winding roller 309 will be driven to move upward. Since the motor 301 is not rotating at this time, the first winding roller 304 is not rotating, that is, the bottom of the rope 306 is in a fixed state at this time. As the table top 104 drives the second winding roller 309 to rise, the rope 306 will apply a downward pulling force to the second winding roller 309, thereby driving the second winding roller 309 to move upward. Figure 8 In the state shown, rotate counterclockwise to dynamically adjust the angle between the computer screen 101 and the table top 104 during the rising process of the table top 104. The higher the height of the table top 104, the smaller the angle between the computer screen 101 and the table top 104, thereby increasing the viewing angle of the screen. At this time, the solenoid valve 209 is in a closed state and will not affect the state of the maintenance component.

[0049] When teaching is required, Figure 1 On the basis of the state shown, the electric telescopic rod 208 is controlled to move downward synchronously with the electric push rod 203, thereby driving the table top 104 to move horizontally downward for a distance. As the table top 104 drives the second winding roller 309 to descend, the distance between the first winding roller 304 and the second winding roller 309 decreases, and the rope 306 changes from a taut state to a loose state. Under the action of the two coil springs 308, the cylindrical rod 307 is driven Figure 8 In the state shown, the support plate 105 is rotated clockwise to rotate upward, thereby increasing the angle between the computer screen 101 and the table top 104, making it easier for the teacher to teach.

[0050] When it is necessary to work, the electric telescopic rod 208 is controlled to move downward synchronously with the electric push rod 203, thereby driving the table top 104 to continue to move downward. As the table top 104 drives the second winding roller 309 to descend, the distance between the first winding roller 304 and the second winding roller 309 decreases, and the rope 306 changes from a taut state to a slack state. Under the action of the two coil springs 308, the cylindrical rod 307 is driven Figure 8In the state shown, rotate clockwise to rotate the support plate 105 upward, thereby increasing the angle between the computer screen 101 and the table top 104. At this time, the height of the table top 104 is the same as the height of the office desk, which is convenient for teachers to work in the classroom.

[0051] When it is necessary to inspect the main machine inside the cabinet 109, the electric telescopic rod 208 is controlled to move upward synchronously with the electric push rod 203, thereby driving the table top 104 to move horizontally upward. During the movement, the extension speed of the electric telescopic rod 208 is increased, so that the displacement between the electric telescopic rod 208 and the electric push rod 203 is different, and the vertical rod 206 moves a longer distance, so that the rear end of the table top 104 tilts upward during the rising process. When the table top 104 moves to the highest point, the vertical rod 206 is extended to the longest state. At this time, when the table top 104 is at the highest position, the rear end of the table top 104 also swings upward to reach the maximum tilt state. At the same time, during the extension of the electric telescopic rod 208, the solenoid valve 209 is controlled to open, so that the solenoid valve 209 and the high-pressure hose 202 are connected to each other. During the upward movement of the piston plate 207, the gas between the piston plate 207 and the rectangular tube 201 is squeezed into the high-pressure hose 202 to push the multi-stage pneumatic telescopic rod 401 is extended, and when the limit frame 402 drives the limit block 403 and the rectangular plate 404 to move backward, it will drive the rectangular block 407 to move backward synchronously. Under the constraints of the guide rail 406 and the limit frame 402, the rectangular plate 404 can move upward while extending backward, so that the host computer located inside the cabinet 109 can be supported out for easy maintenance and disassembly. At the same time, the outer side of the guide rod 408 is always in contact with the inner side of the triangular block 405. When the rectangular plate 404 moves backward, When the mainframe is moved, under the constraint of the hypotenuse of the triangular block 405, the guide rod 408 will continue to move outward, so that the two rectangular boxes 409 move outward, driving the two clamping plates 412 to release the clamping of the mainframe, making it convenient for the maintenance personnel to take out the mainframe. At the same time, the table top 104 is also in the highest state, and the back side of the table top 104 is tilted upward, which can effectively prevent the protruding table top 104 from hitting the head of the maintenance personnel. At the same time, as the table top 104 rises and turns, it will pull the second winding roller 309 in Figure 8 In the state shown, the computer screen 101 is hidden in the interior of the table top 104 by rotating counterclockwise, so as to prevent the maintenance tools from causing damage to the computer screen 101 and protect the computer screen 101 .

[0052] When the smart podium needs to be moved over a short distance, the electric telescopic rod 208 is controlled to move downward synchronously with the electric push rod 203, thereby driving the table top 104 to continue to move downward. At the same time, the rope 306 will be loosened, and the synchronous control motor 301 will rotate. Figure 8In the state shown, the support frame 204 is driven to rotate counterclockwise, the relaxed rope 306 is reeled up, and the support plate 105 is pulled downward to rotate, so that the computer screen 101 is hidden inside the table top 104. In this process, the solenoid valve 209 is opened, and the piston plate 207 moves downward to generate negative pressure inside the rectangular tube 201, so that the multi-stage pneumatic telescopic rod 401 continues to shrink, thereby pulling the rectangular plate 404 to continue to move forward, so that the two rectangular boxes 409 continue to move inward, increasing the clamping plate 412 on the host. The clamping force is applied, and the table top 104 moves to the lowest point, which is convenient for moving the smart podium and protecting the computer screen 101 at the same time. The clamping force is applied inward to the host to reduce the vibration of the host when the smart podium moves a short distance. The host is clamped and the vibration is reduced. Then the two electric push rods 203 begin to extend upward, driving the front end of the table top 104 to move obliquely upward, and the raised section on the rear side of the table top 104 is stored in the interior of the baffle 103, thereby reducing the side cross-section of the smart podium and making it more convenient to move in the classroom.

[0053] It should be noted that: through the cooperation of the adjustment component and the winding component, the height and inclination of the table top 104 can be adjusted, so that the table top 104 can cope with different teaching states. During the lifting and lowering process of the table top 104, the angle between the table top 104 and the computer screen 101 is dynamically adjusted. The higher the height of the table top 104, the smaller the angle between the computer screen 101 and the table top 104, thereby increasing the viewing angle of the screen. Through the cooperation of the adjustment component, the maintenance component and the winding component, the rectangular plate 404 can be extended backward and moved upward at the same time, so that the mainframe located inside the cabinet 109 can be supported out, which is convenient for maintenance and disassembly, and at the same time, the two clamping plates 412 can be driven to release the clamping of the mainframe, making it convenient for maintenance personnel to take out the mainframe. The inner side of the table top 104 is tilted upward, which can effectively prevent The protruding table top 104 is prevented from hitting the maintenance personnel's head. At the same time, as the table top 104 is raised and flipped, the computer screen 101 is hidden inside the table top 104 to protect the computer screen 101. When the smart podium needs to be moved a short distance, the computer screen 101 is hidden inside the table top 104, and the clamping force of the clamping plate 412 on the host is increased to protect the computer screen 101. An inward clamping force is applied to the host to reduce the vibration of the host when the smart podium moves a short distance. Then the two electric push rods 203 begin to extend upward, driving the front end of the table top 104 to move obliquely upward, and a protruding section on the rear side of the table top 104 is stored in the interior of the baffle 103, thereby reducing the side cross-section of the smart podium and making it more convenient to move around the classroom.
