Description

Technical Field

[0001] The present invention relates to the technical field of teaching equipment, and in particular to an intelligent teaching device. Background Art

[0002] In the process of continuous development and evolution of modern education, teaching methods and equipment continue to innovate to adapt to diverse teaching scenarios and needs. In traditional classrooms, multimedia teaching equipment has been widely used since the early projectors were paired with projection cloths. The projector needs to be installed at a specific location on the ceiling of the classroom, and the projection cloth is mostly fixed high on the wall in the form of a scroll and unfolded when in use. Although it enriches the teaching display form to a certain extent, the disadvantages are gradually becoming apparent. On the one hand, the projection cloth is easily contaminated with dust and wrinkles when hung for a long time, resulting in impaired clarity of the projected image and poor color reproduction. Especially when the light control in the classroom is not good, it is difficult for students in the back row to see the screen content clearly, which greatly affects the teaching effect. Even with regular maintenance and cleaning, as the years of use increase, the aging of the material will also weaken the image quality.

[0003] With the maturity of smart display technology driven by science and technology, some classrooms have tried to introduce independent large-screen smart displays to replace projection cloths. They can be wall-mounted or installed on a floor-standing bracket. However, the wall-mounted display is difficult to adjust after the position is fixed. During installation, it is necessary to drill holes and lay wires on the wall, which damages the wall structure and makes subsequent changes cumbersome. Although the floor-standing bracket type is more flexible, it takes up a lot of valuable activity space in front of the podium when classroom space is limited, which can easily hinder the movement of teachers and students. In addition, the bracket has limited stability and is in danger of tipping over in the event of a collision. Summary of the invention

[0004] The purpose of the present invention is to solve the problems that the existing intelligent display screen can be mounted on a wall or on a floor bracket, but the wall-mounted display screen is difficult to adjust after the position is fixed, and it is necessary to drill holes and wire the wall during installation, which destroys the wall structure and makes subsequent changes cumbersome; although the floor bracket type is more flexible, it occupies a large amount of valuable activity space in front of the podium when the classroom space is limited, which easily hinders the movement of teachers and students, and the bracket has limited stability and is in danger of tipping over in case of collision.
