Technical Field

[0001] The present invention relates to the technical field of display devices, and specifically to a teaching display device for education. Background Art

[0002] Multimedia is an indispensable device concept in modern education with modern educational technologies such as computers, projectors, slides, display stands, videos, radios, movies, electronic whiteboards, computers, etc. It uses modern educational theories and technologies to design, develop, apply, manage, and evaluate the teaching process and resources to achieve the theory and practice of teaching modernization. An educational display device refers to a display device used for teaching and learning, which can assist students in improving the teaching effect and interactivity.

[0003] Based on the above, the inventor found that the existing ones mainly have the following deficiencies. For example, the existing teaching display devices are supported by a support frame and placed inside the classroom, which not only occupies space but is also prone to tipping over due to being hit by students. At the same time, traditional teaching display devices have problems such as insufficient interactivity and single functions. With the development of educational informatization, there is an urgent need for a multifunctional and highly interactive teaching display device. Summary of the Invention

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0024] Embodiment 1: Please refer to Figures 1-4 , the specific embodiments of the present invention are as follows: Its structure includes a podium table 1, with a sound hole 2 and a control switch 3 provided at the side end of the podium table 1, and a voice recognition module 4 provided at the top of the front end of the podium table 1; inside the podium table 1, there is a lifting base 11, which is slidably matched with the end face of the limiting strip 15, and an LED touch screen 12 is fixedly installed on the end face of the lifting base 11. A top cover 13 is provided on the top of the podium table 1. The lifting base 11 is threadedly matched with a bolt transmission rod 14. The upper and lower ends of the bolt transmission rod 14 are respectively rotatably connected to the inside of the podium table 1. The bolt transmission rod 14 is meshed with a servo motor 16. A computer 17 is provided at the bottom end inside the podium table 1. A loudspeaker 18 is provided at a position inside the podium table 1 corresponding to the sound hole 2. A main control display screen 19 is provided on the upper end face of the podium table 1. Through the LED touch screen 12, teachers can conduct auxiliary teaching. At the same time, the voice recognition module 4 can recognize the voices of students and teachers and convert them into text for analysis, and generate audio, video, pictures or text for interaction according to the results of the text analysis.

[0025] A extension plate 111 is provided at the rear end of the lifting base 11. A threaded hole 112 is provided on the end face of the extension plate 111, and the threaded hole 112 is threadedly matched with the bolt transmission rod 14. A sliding clamping seat 113 is provided at the front end of the lifting base 11. By the cooperation of the bolt transmission rod 14 and the threaded hole 112 to drive the lifting base 11 to move up and down, the sliding clamping seat 113 can be clamped on the end face of the limiting strip 15 to increase stability.

[0026] A rubber soft pad 114 is provided on the top of the lifting base 11, which can support the bottom of the LED touch screen 12. The LED touch screen 12 can be fixedly installed in the bolt hole 115 by bolts. A passive infrared sensor 116 is provided on the left side of the top of the lifting base 11. By the passive infrared sensor 116 emitting infrared rays and receiving the reflected signals, the distance between the lifting base 11 and the top end inside the podium table 1 can be measured, so that the lifting base 11 stops automatically when it rises to the set position.

[0027] Based on the above embodiments, the specific working principle is as follows: The control switch 3 is used to control the opening of the top cover 13, and then the servo motor 16 meshes with the bolt transmission rod 14 to drive the rotation, so that the bolt transmission rod 14 can drive the lifting base 11 to move upward through the thread, making the LED touch screen 12 stand upright at the front end of the podium, enabling the teacher to conduct auxiliary teaching through the LED touch screen 12. At the same time, the voice recognition module 4 can recognize the voices of students and teachers and convert them into text for analysis, generate audio, video, pictures or text for interaction according to the results of the text analysis, and can also be operated by touching the LED touch screen 12 with the hand, replacing the traditional way of writing on the blackboard with chalk, and being able to teach students in an environmentally friendly way. And through the bolt transmission rod 14, the lifting base 11 can be driven to move downward through the thread, and the LED touch screen 12 can be hidden inside the podium table 1, which can save the space of the LED touch screen 12 in the classroom and can also avoid the situation of tipping caused by students hitting it.

[0028] Embodiment 2: Please refer to Figures 5-6 , the specific embodiments of the present invention are as follows: On both sides of the top cover 13, there are rotating shafts 131 rotatably connected to the top of the podium table 1. On both sides of the end face of the top cover 13, there are respectively electric telescopic rods 132. The side of the electric telescopic rod 132 away from the top cover 13 is rotatably connected to the inner end face of the podium table 1. A limiting structure 133 is fixedly installed on the front end face of the top cover 13. By simultaneously extending or shortening the two electric telescopic rods 132, it plays a role in protecting the LED touch screen 12.

[0029] The limiting structure 133 is provided with a limiting frame 133, which is fixedly connected to the end face of the top cover 13. Inside the limiting frame 133, there is a limiting card slot 134. At the top of the limiting card slot 134, there are two elastic strips 135, and a lower pressing plate 136 is fixedly connected to the end faces of the two elastic strips 135. By covering the top cover 13 downward, the limiting frame 133 made of foam material can cover the top of the LED touch screen 12 for fixation.

[0030] The electric telescopic rod 132 is movably matched with the end face of the top cover 13.

[0031] The elastic strip 135 is made of spring steel material, and the end face of the elastic strip 135 has a 90-degree angle, having good elasticity to support the lower pressing plate 136.

[0032] Based on the above embodiments, the specific working principle is as follows: The control switch 3 can be used to control the two electric telescopic rods 132 to extend simultaneously, supporting the top cover 13 to turn upwards, facilitating the upward lifting of the LED touch screen 12. Moreover, when the electric telescopic rods 132 extend and contract simultaneously, they can drive the top cover 13 to turn downwards to cover the top of the podium table 1, playing a role in protecting the LED touch screen 12. Then, when the top cover 13 covers downwards, the limiting frame 133 made of foam material can cover the top of the LED touch screen 12, preventing the LED touch screen 12 from shaking due to the podium table 1 being impacted. Furthermore, the lower pressing plate 136 is supported by the elastic strip 135 to contact the top of the LED touch screen 12, which can improve the stability of the support for the LED touch screen 12 and avoid the situation where the LED touch screen 12 is damaged.

[0033] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered to be within the scope described in this specification.

[0034] Therefore, from any perspective, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be encompassed within the present invention. Any reference signs in the claims should not be regarded as limiting the claims involved.
