Novel multifunctional desk

Abstract

The invention discloses a novel multifunctional desk which comprises a multistage desk layer unit and a drawer multifunctional unit. The multistage desk layer unit comprises a first-stage desk layer component, a second-stage desk layer component, a drawing lifting transmission mechanism and a real-time imaging mechanism are arranged below the first-stage desk layer component, and an automatic cleaning mechanism is arranged in the drawer multifunctional unit. The objective of drawer cleaning is achieved by driving a broom to move back and forth through forward-backward rotation of a motor, anda function of drawer cleaning can be realized by only pressing a button switch once; the drawing lifting transmission mechanism controls the motor through a switch, and the motor drives transmission teeth to drive a straight-tooth rack for lifting motion in the vertical direction so as to realize desktop angle adjusting and lifting at any angle, so that the novel multifunctional desk is more humanized and scientific and can effectively prevent shortsightedness and humpback; a wireless camera of the real-time imaging mechanism transmits a desktop image to a main control device, the main controldevice is connected with a simple projector to convert the desk image into projection on a curtain so as to achieve the objective of real-time imaging.

Description

technical field [0001] The invention relates to the technical field of intelligent learning equipment, in particular to a novel multifunctional desk. Background technique [0002] With the continuous development and progress of the times, human beings have made great progress in many aspects. For example, multimedia integrated classrooms have appeared in teaching, which has brought great convenience to teachers' teaching and students' learning. Surveys and sampling surveys show that more than 84% of students and teachers are dissatisfied with the current desks: students think that drawing can only be done on special drawing tables and drawing rooms, and they must carry T-squares and drawing tool kits every time they draw. In addition, it often occurs that the drawing tools are forgotten to be carried and the drawings are not firmly fixed when drawing, which leads to rework; the cleaning of the desk drawers is very inconvenient. In addition, the survey found that the current...

Problems solved by technology

Due to the relatively trivial drawing tools, students often forget to bring rulers or compasses, and return to pick them up, resulting in the drawing not being completed on time; when drawing, it takes a lot of time to fix the drawing and draw the positioning line; second, the distance between the desks Smaller, it is very inconvenient to clean the inside of the drawer. You need to bend over 90°, and you have to stretch the broom or rag to the inside of the drawer to clean it. Due to the inconvenience of cleaning, it may even be cleaned casually, or even not cleaned, resulting in the corners inside the drawer A lot of sundries and rubbish are accumulated; thirdly, during classroom exercises, course tests and drawing, teachers generally report that the functions of the desks are too single, and they cannot keep abreast of each student's learning situation, which is not conducive to the further development of teaching. Therefore, this book is urgently needed Those skilled in the art design a kind of multifunctional desk that can solve the above problems
