An electromagnetic braille display device

Abstract

The present invention relates to the technical field of Braille display, in particular to an electromagnetic Braille display device, which includes a display area, a control area and a transmission area. The display area is provided with at least one row of Braille display units, and one Braille display unit includes six touch screens. hole, the control area is provided with a page-turning button and a switch button for controlling the switching of Braille information on the display area, a motor is provided in the motor room of the transmission area, and a cross-flow centrifugal impeller is provided in the fan room; the present invention A display area with a touch hole is designed, and the booster device is used to control the air flow of the local touch hole to realize the air column ejected outward. When the user touches the position of the touch hole, he will feel the air column The formed protrusions replace the original rigid protrusions, thereby effectively avoiding the situation that the normal movement of the lifting structure is affected by sweat and dust pouring into the gaps, and it is more convenient to use and does not require more cleaning.

Description

Technical field [0001] The invention relates to the technical field of Braille display, in particular to an electromagnetic Braille display device. technical background [0002] With fast touch speed and high recognition, it is the most important reading method for blind people. However, the traditional Braille books are expensive, complicated and time-consuming. Moreover, the published Braille books are few, single in variety, lagging in information, small in information, bulky and inconvenient to carry. These factors make the traditional Braille books far from meeting the reading needs of the blind. How to use modern science and technology to develop a barrier-free reading tool for the blind-Braille reader, has increasingly become the focus of social attention. [0003] Therefore, the invention with the application number of CN201410632715.9 discloses a layered electromagnetic Braille display device and Braille reader, which adopts the working principle of electromagnetic induc...

Problems solved by technology

[0003] Therefore, the invention with the application number CN201410632715.9 discloses a layered electromagnetic braille display device and a braille reader, which adopts the working principle of electromagnetic induction and can display one or more lines of braille characters to meet the reading and learning needs of blind people. The significance to the society is huge. In addition to the electromagnetic braille display device, there are also pneumatic and memory alloy methods. The braille display needs to be displayed in a way that a bump pops up in a groove to facilitate the perception of the bump. However, because it is something that is often touched by hands, sweat and dust will inevitably adhere to the panel, especially for people whose hands are prone to sweating. Most of the products in the prior art are integrated, and the panel is not easy to disassemble and clean. When sweat and dust are adhered to the gap between the bumps and the grooves and gradually accumulate, some bumps may not be able to pop up, and it is difficult to clean them off, so it cannot meet the needs of users
