Abstract
The utility model discloses a kind of reading aid for blindmen, comprise base plate, middle plate and top board, base plate, middle plate are connected by bolt with top board, base plate, all have gap between middle plate and top board; Base plate is provided with the electromagnet of more than three, electromagnet passes through Single-chip Controlling, top board has the through hole that position consistent with electromagnet quantity is corresponding, and through the carriage release lever having position consistent with electromagnet quantity corresponding on middle plate, the bottom of carriage release lever is provided with permanent magnet.Structure of the present utility model is simple, and cost is low.
Description
Technical field
The utility model relates to reading aid for blindmen.
Background technology
Braille or claim braille, type aims at blind person's design, by the word of tactilely-perceptible.On paper, produce the salient point of various combination through a letter stencil, some word machine, braille printer etc. and form.Braille is made up of 63 coded characters, and each character is arranged in a rectangle having 6 some positions by a little of 1 ~ 6 projection.In order to confirm 63 different point types or Braille, be from left to right from top to bottom 1-2-3 during several some position, then from right to left from top to bottom 4-5-6.The braille of these projections on ground paper, can touch gently with finger and read.Wherein, " Blair's character list " as universally acknowledged formal braille, its 6 points can show formation and its simplest meaning of each character.China announces new braille in nineteen fifty-three, belongs to phonetic system, has used for reference 6, Blair's embossment system.But because translator of Chinese becomes the process of braille to be that Pictest sound has come, there is two large problems in such interpretative system.One is because Chinese character is very many, and 1000 conventional Chinese characters are translated out very complicated completely, because the phonetic of Chinese character is split and programmed is very difficult; Two is that Chinese character exists polyphone, and in the process of translation, some Chinese character can not very accurate translation be out.Therefore, we simplify language, and changing into is that translator of English becomes braille.English has very clear and definite letter contrast translation.Implement simpler than translator of Chinese many.
According to ASSOCIATE STATISTICS, China is the country that world blind person is maximum, about has 5,000,000, accounts for 18% of whole world blind person's mouth.And Today, most blind person is because self-ability problem, so that can not equally with ordinary people learn.Traditional books for the blind are more thick and heavy than common books and carry inconvenience.Although have braille reader now, similarly be that the e-book of current trend is general, the status of books for the blind can not be replaced.Braille point shows device then because of selling at exorbitant prices, and not all blind person can be affordable.
Summary of the invention
It is simple that the purpose of this utility model is to provide a kind of structure, and cost is low, easy to operate reading aid for blindmen.
For achieving the above object, reading aid for blindmen, comprises base plate, middle plate and top board, and base plate, middle plate are connected by bolt with top board, base plate, all has gap between middle plate and top board; Base plate is provided with the electromagnet of more than three, electromagnet passes through Single-chip Controlling, top board has the through hole that position consistent with electromagnet quantity is corresponding, and through the carriage release lever having position consistent with electromagnet quantity corresponding on middle plate, the bottom of carriage release lever is provided with permanent magnet.
Said structure, utilize the exclusion principle of magnet to realize the motion of carriage release lever, realize the function that Braille convex-concave appears in one's mind, concrete principle is: by the corresponding electromagnet energising of Single-chip Controlling, once electromagnet energising, then corresponding permanent magnet can be subject to repulsive force, thus promotion carriage release lever moves upward, and allows the upper end of carriage release lever give prominence to through hole, therefore, the structure of reading aid for blindmen of the present utility model is simple, and convenient and simple for operation, cost is low.
Further, the below that carriage release lever is positioned at top board is provided with limited block, and described limited block can play spacing effect to moving upward of carriage release lever.
Further, the middle part of carriage release lever is provided with breach, and the side of breach is the bottom-up inclined-plane extended towards carriage release lever center; Middle plate is provided with the swash plate extend in breach.This structure, when carriage release lever moves upward, because breach is inclined-plane, therefore, swash plate can be continuous near inclined-plane and even contact, after the side of breach and the extruding force of swash plate acquire a certain degree, even if electromagnet power-off, also can prevent carriage release lever from resetting because of Action of Gravity Field, serve the effect of self-locking.

Fig. 1 is the stereographic map of reading aid for blindmen.
Fig. 2 is the exploded view of reading aid for blindmen.
Fig. 3 is the schematic diagram of carriage release lever.
Fig. 4 is the enlarged drawing of A in Fig. 2.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further elaborated.
As shown in Figure 1 to Figure 2, reading aid for blindmen comprises base plate 1, middle plate 2 and top board 3, and base plate 1, middle plate 2 are connected with nut by bolt 4 with top board 3, base plate 1, all has gap between middle plate 2 and top board 3; Base plate 1 is provided with the electromagnet 5 of more than three, electromagnet 5 passes through Single-chip Controlling, top board 3 has the through hole 31 that position consistent with electromagnet quantity is corresponding, through the carriage release lever 6 having position consistent with electromagnet quantity corresponding on middle plate 2, as shown in Figure 3, the below that carriage release lever is positioned at top board is provided with limited block 61, and the middle part of carriage release lever is provided with breach 62, and the side of breach 62 is the bottom-up inclined-plane extended towards carriage release lever center.The bottom of carriage release lever is provided with permanent magnet 7.As shown in Figure 4, middle plate 2 is provided with the swash plate 8 extend in breach.
Said structure, utilize the exclusion principle of magnet to realize the motion of carriage release lever, realize the function that Braille convex-concave appears in one's mind, concrete principle is: by the corresponding electromagnet energising of Single-chip Controlling, once electromagnet energising, then corresponding permanent magnet can be subject to repulsive force, thus promotion carriage release lever moves upward, the upper end of carriage release lever is allowed to give prominence to through hole, when carriage release lever moves upward, because breach is inclined-plane, therefore, swash plate can constantly near inclined-plane and even contact, after the side of breach and the extruding force of swash plate acquire a certain degree, even if electromagnet power-off, also can prevent carriage release lever from resetting because of Action of Gravity Field, serve the effect of self-locking.The structure of reading aid for blindmen of the present utility model is simple, and convenient and simple for operation, cost is low.Described limited block can play spacing effect to moving upward of carriage release lever.
