Electric lifting interactive electronic white board

Abstract

The invention relates to an electric lifting interactive electronic white board. A motherboard device can slide up and down to be arranged on a bracket, an electric lifting device is arranged on the bracket and connected with the motherboard device for lifting the motherboard device, preferably, a button switch module and a driving device of the electric lifting device are mutually connected and mounted on the bracket, a rotating shaft is rotatably arranged in the bracket, the driving device is connected with the rotating shaft to drive the rotating shaft, a rope wheel is mounted at the upper part of the bracket, the rotating shaft winds the rotating shaft through a rope to be connected with the motherboard device which is arranged on a guide rail of the bracket and can be folded. The electric lifting interactive electronic white board also comprises a remote controller, a limit switch protection device and a projector equipment hanging device. The invention has smart design, can be used for instantly adjusting the vertical position of the electronic white board, is convenient and comfortable to use, greatly improves the working efficiency, can be folded to reduce occupied space and be conveniently conveyed and therefore lays a solid base for the further development of modern education modes and teaching modes.

Description

technical field [0001] The invention relates to the technical field of electronic education and teleconferencing systems, in particular to the technical field of electronic whiteboards, in particular to an electric lifting interactive electronic whiteboard. Background technique [0002] In modern society, people pay more and more attention to education, and at the same time, more and more facilities and funds are invested in education. However, in the traditional teaching listening mode, there is often one blackboard in one classroom, and the students sitting behind cannot clearly see the words on the blackboard, causing eye fatigue, easy to form myopia, and at the same time unable to take notes completely, so It will greatly affect the efficiency and quality of the lectures. [0003] In the prior art, there is a multimedia telephone teaching mode, in which a lecture display terminal connected through a wired network is installed on each person's seat, and part of the conte...

AI Technical Summary

Problems solved by technology

Among them, the electromagnetic induction electronic whiteboard is easy to be scratched. Once a scratch occurs in the middle, the whole board may be scrapped, and because of the high cost of the receiving coil film, it is not realistic to make a large-area display panel, which brings inconvenience to use.

Infrared electronic whiteboards are easily affected by strong infrared light, and the positioning accuracy is not high

Ultrasonic electronic whiteboards are greatly affected by temperature, and the positioning accuracy is uneven

Resistive film electronic whiteboards are difficult to write. When the strength is not enough, the handwriting will not be displayed. Therefore, it is necessary to write hard, resulting in slower writing speed. In addition, it is easy to scratch, and once scratched, it cannot be used. In addition, due to The production cost is high, and it is not realistic to produce a large-area electronic whiteboard

[0005] None of the above-mentioned electronic whiteboards can be lifted and lowered, so that the electronic whiteboard cannot be adjusted to a suitable position according to the height of the user, making it uncomfortable to use; nor can the position of the electronic whiteboard be adjusted at any time according to the use of the electronic whiteboard. When the upper part of the electronic whiteboard needs to be used, It is necessary to stand on tiptoe, even if you stand on tiptoe, you still cannot reach it, and when you need to use the lower part of the electronic whiteboard, you need to bend over, which is very inconvenient to use
