FIG. 1
[001] The disclosure relates to the technical field of smart class, and in particular, to a smart cloud terminal for smart class teaching.
[002] Smart class is a novel information-based class model developed based on dynamic learning data analysis and the application of cloud, network and terminals. It is directed by the constructive learning theory to create a smart class teaching environment by using the Internet Plus model and new generation information technology such as big data and cloud computing. Digitized and intelligentized operations are achieved in the aspects of teaching decision making, evaluation feedback, interaction and resource push, promoting whole innovation of traditional class teaching contents and modes. Advanced technical support is provided for smart teaching and learning. There have been a wide variety of smart cloud terminals for smart class, one of which is known as a smart platform.
[003] However, currently commercially available smart platforms may still have the following disadvantages in practical use: first, teachers using an existing smart platform have different heights, while a touch screen of the existing smart platform is disposed at a fixed height to the floor. In this case, some teachers may teach with incorrect postures for a long time, so they are prone to occupational diseases. Secondly, there is typically no caster at the bottom of the existing smart platform, leading to inconvenient moving of the smart platform. Moreover, although universal wheels are provided at the bottoms of some smart platforms, the entire smart platform has poor stability because the universal wheels can rotate in the horizontal and vertical directions. Therefore, a smart cloud terminal for smart class teaching is provided herein.
[004] The smart cloud terminal for smart class teaching provided in the disclosure solves the problems of failure in height adjustment and poor portability and stability in an existing smart platform.
[005] To achieve the foregoing objective, the disclosure adopts the following technical solutions:

[032] Operating principle: before using the smart platform body 1, a teacher needs to adjust the height of the touch screen 2 as needed in practice. Specifically, the three-phase gear motor is activated using the foot switch 9 to convert electric energy into mechanical energy and drive the output shaft of the three-phase gear motor 40 to rotate forwards or backwards. In this case, the second synchronizing wheel 41 fixed to the output shaft of the three-phase gear motor may rotate too. Since the first synchronizing wheel 33 is connected to the second synchronizing wheel 41 in a transmission manner by means of the synchronous belt 42, the first synchronizing wheel 33 and the ball screw 32 fixedly connected to the first synchronizing wheel 33 may rotate as well. Further, since the moving part of the ball screw 32 is fixedly connected to the second sliding sleeve 45 by means of the connecting plate 46, the moving part of the ball screw 32 may rise or fall along with the screw rod of the ball screw 32, so as to enable the second sliding sleeve 45 to rise or fall. Thus, the second rectangular tube 4 fixedly connected to the second sliding sleeve 45 may extend out of or retract into the first rectangular tube 3, thereby realizing rising or falling of the touch screen 2 movably connected to the top plate 36 by means of the damping rotating shaft. After the height of the touch screen 2 meets the use requirement, the three-phase gear motor 40 is disconnected from the power source. After the height adjustment is completed, the smart platform body 1 can be started for teaching. When required to move, the smart platform body 1 is turned off and disconnected from an external wire, and then the handle piece 23 is pushed so that the extension spring 28 extend gradually until the arresting piece 24 is completely separated from the first right-angle plate 6. In this case, the first right-angle plate 6 cannot limit the movable plate 15. Then, the movable plate 15 can be opened to expose the hexagon prism 21 fixed to the screw of the screw jack 12. Subsequently, the handle rocker 18 is taken out from the storage box 17 and put on the hexagon prism 21 by means of the hexagon hole 19 formed therein, followed by driving the screw of the screw jack 12 to rotate by using the handle rocker 18. Thus, the universal wheels 20 at the bottom of the support plate 11 can be pushed to move downwards, and the smart platform body 1 can be pushed after the universal wheels 20 come into contact with the ground and the four first right-angle plates 6 are suspended in the air. All the operations are simple. The concave housing 10 is used to protect the three-phase gear motor 40, which improves the overall appearance. Similarly, the three side baffles 7 and the movable plate 15 can conceal the first right-angle plates 6 and the screw jack 12, achieving excellent appearance. With the design of the first sliding sleeves 13 and the first sliding rods 14, the support plate 11 can rise and fall more stably and the support plate 11 will not shake. Two rolling wheels 27 are used to clamp the movable plate 15, so that the handle piece 23 and the arresting piece 24 can slide stably. Compared with example 1, the internal space of the base 5 can keep dry for a long time by means of the desiccant bags 47 used in example 2, so that the rate of oxidative rusting of the screw jack 12 is effectively reduced and the service life of the screw jack 12 is prolonged. The smart platform can be moved conveniently, and the stability thereof in use can be guaranteed. Moreover, the touch screen 2 can be adjusted in height, reducing the probability of a teacher suffering from occupational diseases. In short, the cloud terminal is highly practicable.
