Abstract

The invention belongs to the technical field of electronic equipment, and relates to a driving module, a preparation method thereof and a braille interactive device comprising the driving module. The technical key points are as follows: a plurality of convex points are arranged on one side of the liquid crystal elastomer driving film, and concave areas corresponding to the convex points are arranged on the other side of the liquid crystal elastomer driving film; the stretching conductive coating is coated on the inner side of the concave area, uniformly extends into a set area on the periphery of the concave area, and is connected with an external conductive structure to realize conduction; each protruding point coated with the stretching conductive coating is a driving unit, and the driving units are directionally arranged on the driving module. The driving module in the braille device is prepared by utilizing the good driving performance of the liquid crystal elastomer film, accurately preparing and distinguishing the fixed-point telescopic bulge dot matrix and the non-driving deformation substrate film and combining the good electric heating performance of the ultrathin stretchable conductive nano coating; reversible contraction of the bulged braille dot matrix on the driving module is realized by utilizing electric heat.

Description

technical field [0001] The invention belongs to the technical field of electronic equipment, and relates to a driving module, a preparation method thereof and a braille interactive device including the driving module. Background technique [0002] At present, Braille readers can use advanced image recognition technology to convert text into speech, so as to realize the reception of text information for people with visual impairments. For the actual reading of Braille e-books, most of the related devices or equipment adopt a certain mechanical structure. Display Braille dots, use electromagnetic control and piezoelectric ceramics to realize the protrusion of Braille bumps, and realize the conversion from text to Braille. [0003] The overall rigid structure of the above-mentioned Braille electronic interactive device, especially the bump module, limits the application scenarios, and the structural design is complicated. To display a large number of Braille dots, the number o...
