Description
Technical field
It a kind of shows the utility model relates to a kind of braille display device more particularly to the braille for being particularly shown mechanism
Device belongs to the technical field that braille shows equipment.
Background technique
Braille, also known as braille, type are to design exclusively for blind person, by the text of tactilely-perceptible.It is to pass through that blind person, which reads,
Touch is carried out by the Braille that multiple salient points form.The size of salient point is all special according to blind touch psychology and tactile physiology
Point designs, and dot shape is generally hemispherical or paraboloidal, and salient point bottom diameter is 1.0 ~ 1.6 mm, a height of 0.2 ~
0.5mm, point is away from being 2.2 ~ 2.8mm, just away from for 3.5 ~ 4.0mm.One Braille by 6 fixed points away from salient point form, this
Six salient points are in the column arrangement of three rows two, referred to as a side.
Modern Chinese braille is formulated according to the Braille of Frenchman Louis Blair invention, and there are two types of schemes:
One is prevailing mandarin brailles；One is Chinese double-spelling brailles.Present braille is the most general, and prevailing mandarin braille is according to the Chinese phonetic alphabet
And it is manufactured, a complete Braille is by initial consonant, simple or compound vowel of a Chinese syllable and tone composition.The initial and the final and each Zhan Yifang braille of tone
Braille, therefore to show that a complete Braille needs the space of tripartite.
The blind switch technology of the Chinese is to establish the Chinese phonetic alphabet-braille phonetic bilingual dictionary according to national braille standard, by searching for
The mode of dictionary is realized.Such switch technology is mature, and there are some crossover tool softwares in market, passes through built-in related Chinese
The Chinese character that user inputs is converted to the Chinese phonetic alphabet by dictionary first, then will further according to the Chinese phonetic alphabet-braille phonetic bilingual dictionary
Phonetic switchs to braille phonetic.Tool software determines whether polyphone to the Chinese character called in, and advises if so, being identified by polyphone
Then determine which syllable is most suitable for the word with context semanteme；If not polyphone, then export Chinese spelling by dictionary
Sound character string finally exports the character string combinations of output at braille pinyin combinations.It, can be to common using such tool software
Document carries out the conversion of batch, and stores into related Braille file, transfers use for Braille display.
Braille display is that indispensable a part is read in blindman, by the braille for transferring tool software generation
Braille information in braille file, driving electro mechanical devices form corresponding salient point over the display and touch reading for blind person.
For the Braille display of commercialization at this stage since electronics and mechanical equipment are complicated, technical difficulty is big, so price is high, side's braille
Price be probably 100 to 150 dollars, i.e., the price of the Braille display of one 40 sides is 4000 to 6000 dollars, and one
The Braille display of a 80 side then needs 8000 to 12000 dollars.
The driving method of Braille display at this stage has following several: piezoelectric ceramic type, memorial alloy formula, electromagnetic type,
Electro photoluminescence formula and Temperature Control Type.
The invertibity of piezoelectric effect is utilized in piezoelectric ceramic type Braille display.Piezoelectric bimorph is that have two panels on the contrary
The piezoelectric ceramic piece of polarization direction fits closely together, and after applying positive voltage to it, a Fang Shenchang, another party then shortens,
Therefore bending deformation is generated, the driving needle for being fixed on piezoelectric ceramics on piece also moves up therewith.The power consumption for displays is low, generates
Power is big, and light weight, corresponding speed is fast, can fast implement braille and show.But it is inconvenient that the piezoelectric patches of the display is replaced, and structure is multiple
Miscellaneous, production and processing technology complexity is cumbersome, and part manufacturing cost is high, and difficulty of processing is big.
Electromagnetic type Braille display is to pacify times rule and magnet homopolar-repulsion phenomenon using galvanomagnetic-effect, same to cross permanent magnet
The magnetic force generated with electromagnet, to control the rising and reset of salient point.Under idle state, driven made of permanent magnet
Suction is generated for iron core, because iron core is fixed, therefore drives needle that can move downward under the action of suction, makes salient point retraction
Kong Zhong.In the operating condition, direct current is passed to electromagnet coil, magnetic field caused by hot-wire coil can balance out permanent magnet production
Raw magnetic field, driving needle just stretch out hole under the drive of stiff spring and form braille salient point.The device is easy to control, can generate institute
The haptic force needed, braille contact spacing can be met the requirements.But its complicated in mechanical structure, moving parts are more, and overall structure is strong
It spends poor.
It should be noted that this case is that indication mechanism structure and indication mechanism structure driven structure based on product carry out
Design, it is unrelated with the software realization of braille.
