Description
Technical Field
The invention belongs to the technical field of reading bookshelves, and particularly relates to a myopia-preventing reading bookshelf based on magnetorheological materials, which is applied to the automatic adjustment of the posture of the myopia-preventing bookshelf.
Background
Under the common conditions, children are difficult to voluntarily keep correct sitting postures for a long time when reading and writing, and are more difficult to ensure correct reading and writing distances, and the writing is described according to the related articles for preventing myopia of students in the middle school biology teaching plan compiled and published in 1989 of Beijing Master university: the reading and writing postures are correct, the head of the book cannot be tilted and the book cannot be obliquely looked at, and the distance between eyes and the book is kept between 30 and 33 centimeters.
The Chinese utility model CN93233117.3 discloses a multifunctional writing case device which is characterized in that a reading bookshelf, a vision limiting device and a writing case are organically connected into a whole. It adds a reading bookshelf composed of fixed frame in the existing stationery box, fixes the opened book and changes the sight angle; a vision limiting device composed of a telescopic pull rod can supervise and force a user to voluntarily correct the sitting posture and keep the correct reading and writing distance, thereby achieving the purpose of preventing myopia.
The patent has the disadvantages that the sitting posture of a reader is limited by the fixed limiting device, the sitting posture of the reader is required to be adjusted by the reader consciously, the reader can unconsciously tend to a comfortable but irregular reading posture when the attention of the reader is focused, and the reader cannot be effectively limited or reminded to change the reading posture.
Chinese patent CN201621049444.5 discloses an anti-myopia reading bookshelf, and discloses a scheme for detecting the distance of a reader by using a distance measuring sensor and reminding the reader to adjust the sitting posture through a speaker.
The patent has the disadvantages that as long as the distance from the face of the reader to the bookshelf is detected to be not in accordance with a set value, the bookshelf can give a prompt to influence the reading attention of the reader, children and students with younger ages are more easily distracted, and the function is used as a point of interest for playing.
In conclusion, the existing reading bookshelf has the defects that the relative position posture between the bookshelf and a reader cannot be automatically adjusted, the reading attention is influenced by the detection means, the detection means is not practical, and the like.
However, myopia is a health problem for the whole population, and the more children of low age wear myopia glasses, the better the myopia, so that the good reading posture is a problem which needs to be solved urgently.
In summary, there is an urgent need for a reading bookshelf with an automatic adjustment function to automatically adjust the posture of the bookshelf relative to the reader, and detect and remind the reader to adjust the reading posture.
Disclosure of Invention
The invention aims to provide a reading bookshelf with an automatic adjusting function, so that the relative position and posture between the bookshelf and a reader can be automatically adjusted by the bookshelf, and the reader is detected and reminded to adjust the reading posture.
In order to achieve the purpose, the invention provides a myopia-preventing reading bookshelf based on magnetorheological materials.
The invention adopts the following specific technical scheme:
an anti-myopia reading bookshelf based on magnetorheological materials, comprising:
