Embodiment Construction

[0043] The technical solution will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0044] Full page braille displays:

[0045] 1. Examples of Braille bump control structure:

[0046] Picture 1-1 It is a cross-sectional schematic diagram of an initial state of a dot unit (that is, a braille concave-convex dot control structure) of the full-page braille display in this example. 1.1 in the figure is the character push rod; 1.2 is the panel of the dot display; 1.3 is the movable plate; 1.4 is the elastic contact surface between the movable plate and the ejector rod under normal conditions (that is, the elastic contact surface on the inner wall of the waist hole); 1.5 is the movable plate The groove at the bottom; 1.6 is the rod-shaped protrusion that intersects with the ejector rod in a cross; 1.7 is the armature, which is bonded to the lower end of the character ejector rod; 1.8 is the spring wire for reset; 1.9 is the magne...

Abstract

The invention discloses a Braille convex-concave point control structure, comprising a character post rod, a rod projection, an active board and a control device thereof, and a character post rod motion control device. The rod projection is connected at the lower end of the character post rod which moves up and down through the driving of the character post rod motion control device and the rod projection; the active board is perpendicular to the character post rod, the bottom layer of the active board is provided with a groove; the active board is controlled to translate, and the rod projection enters the groove to drive the character post rod to move up and down. The invention also discloses a progressive full-page driving Braille display, comprising a plurality of square modules each of which is composed of 6 Braille convex-concave point control structures, wherein the structure is arranged in a mode of 3 rows * 2 columns mode; the active boards of the Braille convex-concave point control structures of the square modules in the same line are connected to form an active lath moving together, a waist hole corresponding to the character post rod is arranged on the active lath; in the square modules in the same column, the electromagnetic assemblies of a first Braille convex-concave point control structure, a second Braille convex-concave point control structure and a third Braille convex-concave point control structure in the same column of the square modules are respectively connected to a first driving wire, a second driving wire and a third driving wire which are identical.

Description

technical field [0001] The present invention aims to provide a dot display device capable of converting electronic text into full-page Braille embossed dots, which belongs to the technical field of Braille reading devices, and specifically relates to a control method for Braille full-page embossed dots and a line-by-line driving of full-page Braille dot display. Background technique [0002] A full page of Braille usually contains 25 lines of up to 40 Braille characters (squares), represented by 6 to 8 dots per square arranged in two columns. At present, the braille display that is put into practical use can only display one line of characters, which is very inconvenient to read. Therefore, it is necessary to develop a full-page braille display. Existing braille displays generally use a push rod mechanism, and the push rod is pushed out of the panel by piezoelectric ceramics or electromagnets (or micro motors) to form bumps, and whether the push rod is pushed out at differe...
