[0019] The present invention provides Figures 1 to 6A multifunctional English teaching device shown in the figure comprises: a moving platform 1 and two protective plates 2, two supporting seats 3 are fixedly connected to the top of the moving platform 1, and the two supporting seats 3 are hinged with a same writing board 4 through a pin shaft, a moving groove 5 is provided on the top of the moving platform 1, two sliding grooves 6 are provided on the top of the moving platform 1, and two dovetail grooves 7 are provided on both sides of the two protective plates 2 that are close to each other; The adjustment component includes two fixed blocks 8 fixedly connected to the rear side of the writing board 4, the two fixed blocks 8 are hinged with a rotating rod 9 through a pin shaft, the bottom ends of the two rotating rods 9 are sleeved with a fixed column 10, the two ends of the two fixed columns 10 are fixedly connected to the same moving seat 11, the bottom end of the moving seat 11 is fixedly connected to a moving block 12, and the front side of the moving seat 11 is fixedly connected to a first electric push rod 13; The tilt angle adjustment function of the writing board 4 is realized by the first electric push rod 13. The first electric push rod 13 is fixed to the rear side of the writing board 4 and is connected to the moving seat 11. When the operator needs to adjust the tilt angle of the writing board 4, the first electric push rod 13 can be activated. The pushing action of the electric push rod will cause the moving seat 11 to slide forward along the moving groove 5, and at the same time, through the connected fixed column 10 and the rotating rod 9, the fixed block 8 is pushed, thereby causing the writing board 4 to rotate around the pin of the support seat 3; This design allows the writing board 4 to gradually tilt from a horizontal position to one or more preset angles to accommodate different users' writing postures and teaching needs. For example, some students may prefer a slight tilt angle to write, while others may need a larger tilt angle to maintain a comfortable sitting posture. The precise control of the electric push rod ensures that the tilt angle adjustment is both smooth and accurate, thereby providing a personalized writing experience; The protection component includes two fixed seats 14 fixedly connected to the two ends of the two fixed columns 10 that are far away from each other, the bottom end of the fixed seat 14 is fixedly connected to a slider 15, the top end of the fixed seat 14 is fixedly connected to a second electric push rod 16, the top of the second electric push rod 16 is fixedly connected to a limiting block 17, the left and right sides of the moving platform 1 are fixedly connected to two guide telescopic rods 18, and the two ends of the two guide telescopic rods 18 that are far away from each other are fixedly connected to dovetail blocks 19, and the dovetail blocks 19 are slidably connected in the corresponding dovetail grooves 7.

[0020] The protection plate 2 is designed to protect the writing board 4 when not in use, and to provide a larger writing space when in use. The protection plate 2 is fixed to the top of two fixing seats 14, and each fixing seat 14 is connected to a limit block 17 through a second electric push rod 16. When the writing board 4 needs to be used, the second electric push rod 16 can be started, and the limit block 17 will slide in the inclined groove 27 of the protection plate 2, so that the two protection plates 2 are relatively opened; This opening mechanism not only provides the user with a complete writing area, but also ensures that the protective plate 2 does not hinder writing activities during use. Once the writing or teaching activities are completed, the operator can start the second electric push rod 16 again, so that the limit block 17 slides in the opposite direction, thereby guiding the protective plate 2 to close and cover the writing board 4. This design effectively protects the surface of the writing board 4 from dust, scratches or other potential damage, and prolongs the service life of the teaching device; Four third electric push rods 20 are fixedly connected to the bottom of the moving platform 1, and the bottom ends of the four third electric push rods 20 are fixedly connected to the same rotating disk 21. The bottom of the rotating disk 21 is fixedly connected to three supporting columns 22, and the bottom end of the rotating disk 21 is fixedly connected to a fixed shaft 23, and the bottom end of the fixed shaft 23 is fixedly connected to a motor 24, and the bottom of the motor 24 is fixedly connected to a base 25.

[0021] The height adjustment function is achieved through four third electric push rods 20. These electric push rods are fixed to the bottom of the mobile platform 1 and connected to the four corners of the mobile platform 1. When the height of the device needs to be adjusted to meet the needs of users of different heights, the operator can start the electric push rods. The telescopic action of the electric push rods will push the mobile platform 1 up and down, thereby changing the height of the entire teaching device. This design allows users to adjust the teaching device to the most comfortable height according to their personal height or sitting habits. Whether standing or sitting, they can maintain a correct posture and reduce physical fatigue that may be caused by long-term use; An annular groove 26 is provided at the top of the base 25 , and the bottom ends of the three support columns 22 are slidably connected in the same annular groove 26 . Two inclined grooves 27 are provided at the bottom of the protective plate 2 , and the top of the limit block 17 is slidably connected in the corresponding inclined grooves 27 .

[0022] The limit block 17 and the inclined slot 27 mechanism are designed. The limit block 17 is used to limit the movement range of the protective plate 2 during opening and closing to prevent damage or accidental injury caused by excessive movement. The inclined slot 27 provides a precise guide path, so that each movement of the protective plate 2 is precisely controllable without offset or jump, thereby greatly improving the safety of operation. This design ensures that the protective plate 2 can maintain stable and reliable operation even in frequent use, ensuring the safety of the user.

[0023] The support column 22 is designed to be located in the annular groove 26. This structure allows the support column 22 to rotate freely in the groove, but at the same time it is restricted by the annular groove 26 during the rotation process, thereby increasing the overall stability of the device. When the teaching device needs to adjust the angle or height, the rotation of the support column 22 in the annular groove 26 ensures the balance of the entire device and avoids the risk of tipping over due to an unstable center of gravity. In addition, this design can also provide uniform support on different ground surfaces, whether it is a flat classroom floor or a slightly undulating environment, it can keep the teaching device stable, providing users with a safe and reliable learning platform; The first electric push rod 13 is fixedly connected to a support block 28, the bottom end of the support block 28 is fixedly connected to the top of the moving platform 1, the bottom end of the moving block 12 is slidably connected to the moving groove 5, the slider 15 is slidably connected to the slide groove 6, and four self-locking universal wheels 29 are fixedly connected to the bottom of the base 25. The moving block 12 and the moving groove 5 are both T-shaped.

[0024] Working principle: When using the device, first move the device to a suitable position through the self-locking universal wheel 29, then self-lock the self-locking universal wheel 29 to fix the position, and then start the four third electric push rods 20 according to the needs, the four third electric push rods 20 can push up the mobile platform 1, and the mobile platform 1 can drive the support block 28, the first electric push rod 13, the writing board 4, the protective plate 2 and the moving seat 11 to move to a suitable height, and start the motor 24 synchronously, the motor 24 drives the fixed shaft 23 and the rotating disk 21 to rotate continuously, and drives the three support columns 22 to rotate in the annular groove 26 until the rotation angle of the writing board 4 is adjusted to a suitable position; Finally, the first electric push rod 13 can be started, and the first electric push rod 13 drives the moving seat 11 and the moving block 12 to slide forward in the moving groove 5, and drives the two fixed columns 10, the fixed seat 14 and the slide block 15 to move forward synchronously in the slide groove 6. In the process of movement, under the action of the pin shaft, the bottom ends of the two rotating rods 9 are synchronously rotated outside the fixed column 10, pushing the two fixed blocks 8 to rise until the inclination angle of the writing board 4 can be adjusted to a suitable position; While the second electric push rod 16 and the limit block 17 move forward, the limit block 17 can slide in the inclined groove 27, so that the two protection plates 2 can be relatively opened, and the corresponding two guide telescopic rods 18 can be relatively stretched; When use is completed, restart the first electric push rod 13, the first electric push rod 13 can push the moving seat 11 and the moving block 12 to slide backward in the moving seat 11, and drive the fixed column 10, the fixed seat 14 and the slider 15 to move backward in the slide groove 6, and drive the fixed block 8 and the writing board 4 to flip to a horizontal state through the rotating rod 9 and the pin shaft. While the second electric push rod 16 and the limit block 17 move backward, the limit block 17 can slide in the inclined groove 27, so that the two protective plates 2 can move toward each other and compress the two guide telescopic rods 18, and then start the second electric push rod 16, which can drive the protective plate 2 to move downward until it fits on the top of the writing board 4.

[0025] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
