Description

Foldable Adaptive Smart Desk

technical field

The invention relates to an intelligent desk, in particular to a foldable self-adaptive intelligent desk.

Background technique

Common desks widely used at present have many inconveniences or disadvantages. For example, the height of an ordinary desk is fixed, causing students of different heights to feel uncomfortable when using it; the desktop of the desk is a horizontal plane, and the book needs to be picked up when reading, so that both hands are occupied; or the book can be placed flat and the head can be read. Keeping this posture for a long time will cause cervical fatigue or even injury; ordinary desks with horizontal desktops cannot meet the requirements of manual drawing on the inclination of the desktop. In order to meet the requirements of drawing, most schools use special drawing desks and open up special In this way, the investment is increased. No matter whether the desk is used or not, the classroom area it occupies will not change, which makes the classroom use single and is not conducive to the rearrangement of the classroom during group teaching; in addition, ordinary desks There is no function of prompting students with incorrect sitting postures in time, which is not conducive to correcting bad sitting postures, and poor sitting postures will cause great damage to students' vision, spine, thoracic spine, etc.

In order to change these inconveniences or shortcomings, some improved desk products are provided on the market, which improves some inconveniences of ordinary desks to a certain extent, but brings some new problems or shortcomings, mainly focusing on: (1) The cost is high and expensive, and it cannot be popularized in various schools; (2) it takes up a lot of space when not in use, and cannot save space; (3) many desk products adjust the height by raising or lowering the desktop to suit people of different heights. However, the operation requires the help of other tools or the operation is too complicated, and the requirements for the inclination of the desktop in different usage situations are not considered; (4) Most of the desks on the market use mechanical structures to forcibly limit the distance between the user's eyes and the desktop when using them. For example, methods such as supporting the lower jaw not only increase the structure of the desk, but also easily cause damage to the lower jaw and bring new health problems.
