The present invention relates to the technical field of tactile display for the blind, in particular to a tactile display device, comprising a base, a contact and a driving structure corresponding to the contact, the driving structure is arranged on the base, and the driving structure includes a driving member and an eccentric wheel, the eccentric wheel The outer peripheral surface of the contact is in contact with the contact, and the driving member can drive the eccentric wheel to rotate, so as to drive the contact to reciprocate along a straight line. The driving part of the present invention drives the eccentric wheel to rotate around the center of rotation. During the rotation of the eccentric wheel, the contact point reciprocates along a straight line in a direction perpendicular to the axis of the eccentric wheel, so as to realize the reciprocating rise and fall of the contact point. When a plurality of contacts are arranged on the base of the present invention, adjusting the distance between the contacts can realize the display of traditional Braille, and the use of the present invention with a large format can also form a graphic display and become a display for the blind. The rotating structure of the eccentric wheel controls the rise and fall of the contact, the structure is simpler and more compact, and the addition of the mechanical structure makes the control process more energy-saving.
Description
technical field [0001] The invention relates to the technical field of tactile display for the blind, in particular to a tactile display device. Background technique [0002] Touch reading is fast and highly recognizable, and it is the most important way for blind people to read and watch. However, the special paper for traditional Braille books is expensive, the production process is complicated, and it takes a long time. Moreover, there are few Braille books published, the variety is single, the information is lagging, the amount of information is small, the volume is heavy, and it is not easy to carry. There is no better form for Braille paintings. These factors lead to the fact that traditional Braille works are far from meeting the needs of blind people. Existing tactile display devices are large in size and bulky, and mostly use electronic components inside, which are expensive and consume a lot of power, making it difficult to be widely popularized and applied. Con...
