Description

Novel electromagnetic lattice structure

Technical Field

The utility model relates to the technical field of reading structures for blind persons, in particular to a novel electromagnetic lattice structure.

Background

For the blind, reading is more difficult than normal people, and external information is generally obtained through voice or special braille books, but the information is limited to be obtained only through voice, so that the learning ability is not improved, and the self-learning ability is not fully exerted. The braille books are complex in manufacturing process, the price of the braille books is several times of that of common books, the braille books on the market are less in sales, the blind is difficult to search for book information, and even if the blind is obtained, the braille books are inconvenient to carry. For people who do not receive braille education, the braille cannot be read and understood without knowledge of the braille.

For example, the prior patent publication number is CN113963603A, named as a novel electronic book for the blind, and the design principle is as follows: (1) When the outer surface of the inner shell 1 is in a flat state, the silica gel contact 3 stretches into the hole 2, the coil 5 is not electrified, no magnetic force exists, and the spring 4 is in a non-deformation state. (2) The circuit is electrified, the coil 5 is electrified to generate a magnetic field, F magnetic force > F spring, the attracting magnet 6 moves upwards, and the spring 4 is compressed; (3) When in the protruding state, the silica gel contact 3 stretches out of the hole 2, the coil 5 is mutually attached to the magnet 6, the spring 4 reaches the maximum elastic deformation, the F magnet=F spring, the whole body is in the static state, and the contact is in the protruding state. (4) When the circuit is powered off, the coil 5 loses magnetic force, the F magnet < F spring, the spring 4 starts to recover deformation, at the moment, the spring 4 is in a non-deformation state, and the silica gel contact 3 stretches into the hole 2. The above is the motion of single silica gel contact 3, and through the cooperation of different silica gel contacts 3, can form corresponding characters outside stretching out hole 2, supplies the user to touch the impression. However, the above patent has a certain disadvantage: (1) In the use process of the annular electromagnet, along with the lengthening of the use time, the magnetism of the electromagnet is reduced, the effective range magnetism of the electromagnet cannot be ensured to be within a range value at any time, and when the magnetism no longer meets F magnetism > F bullet, abnormal display occurs on the lattice salient points. (2) The spring can cause irreversible damage to the spring during long-term stressed compression, i.e. relaxation of the spring. Along with the relaxation of the spring, the electromagnetic force required by the salient points of the electronic book for the blind can also be changed, so that the height of synapses is uneven, and the touch judgment of the visually impaired people is influenced.

In order to solve the problems, the proposal is generated.
