Description

Technical Field

[0001] This utility model relates to the field of programming teaching technology, specifically to an Internet of Things (IoT) smart terminal for programming teaching. Background Technology

[0002] IoT smart terminals for programming education generally refer to smart hardware devices or platforms specifically designed for teaching programming and IoT technology, typically consisting of a platform integrating a computer.

[0003] To achieve the above functions, a Chinese patent (publication number: CN218181671U) discloses a teaching terminal. The main body has a multi-functional teaching aid mechanism on its outer side, and a communicator on its right side. In use, silent pulleys move the device to a suitable position, extending the telescopic column in the pre-embedded bucket to a height suitable for operator operation. During the raising and lowering of the telescopic column, an LED warning light illuminates to promptly remind the operator of the raising and lowering process, preventing injury. A foldable table is then unfolded for convenient learning. A handwriting touchscreen or card reader can be used to query or study business administration content. The intelligent display screen can display the query content. The projector can project images and receive data for projection, which is very convenient and fast. Finally, a thermal printer can print business administration materials, facilitating operation and learning, thus fulfilling the function of a multi-functional teaching aid.

[0004] While existing technologies can overcome the shortcomings mentioned above, other problems still exist in their operation: In order to adapt to different user groups, existing teaching terminals are usually designed with height and angle adjustment functions to meet the needs of different users. However, the screen orientation cannot be adjusted quickly, and the terminal lacks the function of remembering user personal data and adjustment parameters. It needs to be readjusted every time it is used, and personalized settings cannot be saved, which reduces the convenience and efficiency of use. Utility Model Content

[0026] Example 1: Please refer to Figure 1 - Figure 6This utility model provides the following technical solution: an Internet of Things (IoT) smart terminal for programming teaching, including a base 1, a mounting box 2 slidably connected to the top of the base 1, and a tabletop 3 fixedly connected to the top of the mounting box 2; a moving plate 4 slidably connected to the middle of the top of the tabletop 3, a mounting box 5 fixedly connected to the top of the moving plate 4, a turntable 6 rotatably connected inside the mounting box 5, bearing balls 7 evenly distributed around the axis of the turntable 6 between the upper and lower inner walls of the mounting box 5 and the turntable 6; the outer side of the turntable 6 is designed with a wave-shaped structure, and annularly distributed elastic limiting pieces 8 are fixedly connected inside the mounting box 5, and the elastic limiting pieces 8 are engaged in the wave-shaped groove on the outer side of the turntable 6; mounting sleeves 9 are fixedly connected to both sides of the bottom of the moving plate 4, and a sliding rod 10 rotatably connected to the bottom of the tabletop 3 and slidably inserted into the mounting sleeve 9; a motor-driven lead screw 11 is provided at the bottom of the tabletop 3, the lead screw 11 is threadedly connected to the inside of the mounting sleeve 9, and the sliding rod 10 and the lead screw 11 are symmetrically distributed; installation A support column 12 is fixedly connected to the top of box 5. A mounting shaft 13 is fixedly connected to the upper end of the support column 12. An adjusting rod 14 is rotatably connected to the outside of the mounting shaft 13. A projector 20 is rotatably connected to the top of the tabletop 3 via an adjustable-angle connecting rod. A worm gear 15 is fixedly connected to the middle of the mounting shaft 13. A worm gear 16 driven by a stepper motor is provided at the top of the adjusting rod 14, and the worm gear 16 meshes with the worm gear 15. A display 17 is fixedly connected to the end of the adjusting rod 14 away from the support column 12. An electric push rod 18 is fixedly connected inside the base 1, and the top of the electric push rod 18 is fixedly connected to the bottom of the mounting box 2 to form a vertical lifting structure. A computer host is provided inside the mounting box 2. A mounting cover 19 is detachably connected to the rear side of the mounting box 2 via a buckle. A controller is integrated inside the computer host. A control panel is provided on the front edge of the tabletop 3. The buttons on the control panel are electrically connected to the controller, and the controller is electrically connected to the stepper motor, the lead screw 11 drive motor, and the electric push rod 18.

[0027] Vertical lifting is driven by electric push rod 18 to slide the mounting box 2 along the base 1 to achieve overall height adjustment. Horizontal movement is achieved through the threaded engagement of lead screw 11 and mounting sleeve 9. Under the guidance of slide rod 10, the moving plate 4 moves laterally along the table surface 3. The wavy outer edge of turntable 6 and elastic limit plate 8 form multi-position positioning. Turntable 6 is connected to adjustment rod 14 via support column 12. Worm gear 16 drives worm wheel 15 to achieve tilt angle adjustment of display 17.

The built-in heat dissipation air duct is linked with the lifting stroke of the electric push rod 18.

[0029] The intelligent memory system is built on the software within the user device. The software allocates independent storage space and account to each registered user. After the user completes the setting of height, horizontal position and display angle parameters, the system automatically saves the adjustment parameters. After the user logs in and the identity is successfully recognized, the automatic adjustment program is triggered. The electric push rod 18 performs vertical positioning first. After reaching the set height, the lead screw 11 drives the motion plate 4 to move to the preset coordinates. Finally, the worm gear 16 reproduces the display angle. In programming teaching scenarios, the teacher can remotely lock the adjustment function of the student terminal and uniformly set the standard operating height.
