Top is fixed with blind aobvious point, and display panel is equipped with the abdicating through hole that multiple positions correspond to blind aobvious point.
As further program of the utility model：The quantity of every group of position power cam is totally six two rows of, with three of row
It position power cam coaxial setting and is driven by single driving motor, the upper line position of blind aobvious point not phase on the power cams of three positions
Together.
As the utility model further scheme：Each driving motor is connect with steering engine controller, each
The steering engine controller is electrically connected with CPU, and the CPU is also electrically connected a SD card for storage file data.
As the utility model further scheme：The steering engine controller is PWM Shield for Arduino,

Compared with prior art, the utility model has the beneficial effects that：Cam and post rod mechanism are weighed using position so that one
Driving motor can control the state of three blind aobvious points simultaneously, to realize a kind of low cost, easily realize it is blind it is aobvious point driving side
Method economizes on resources, at low cost.
Description of the drawings
Fig. 1 is that the structural schematic diagram that cam point shows structure is weighed in a kind of position of braille electronic reader.
Fig. 2 is that the driving schematic diagram that cam point shows structure is weighed in a kind of position of braille electronic reader.
Fig. 3 is that the structural schematic diagram that cam point shows power cam in position in structure is weighed in a kind of position of braille electronic reader.
In figure：1- display panels, 2- driving motors, 3- power cams, 4- mandrils, the blind aobvious points of 5-, 301- partes glabras, 302-
Axis hole, 303- teeth portion.
Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
The every other embodiment obtained, shall fall within the protection scope of the present invention.
Please referring to Fig.1~3, in the utility model embodiment, a kind of position power cam point of braille electronic reader shows structure,
Including multigroup power cam 3 and display panel 1, it includes partes glabra 301 and teeth portion 303 that cam 3 is weighed in position, and the center of cam 3 is weighed in position
Place offers the axis hole 302 for exporting axis connection with driving motor 2, and partes glabra 301 and teeth portion 303 are coplanar with, teeth portion 303
It is made of multiple continuous teeth, and is equipped with mandril 4 between two of which teeth, the top of mandril 4 is fixed with blind aobvious point 5, shows
Showing that panel 1 is equipped with the abdicating through hole that multiple positions correspond to blind aobvious point 5, when driving motor 2 rotates, position power cam 3 starts to rotate,
Drive rising or falling for blind aobvious point 5, blind person that can carry out reading word according to blind aobvious point 5.
The quantity of every group of position power cam 3 is totally six two rows of, with three positions power cam 3 coaxial arrangement arranged and by individually driving
Dynamic motor 2 is driven, and the upper line position of blind aobvious point 5 is all different on three positions power cams 3, this is allowed in 2 turns of driving motor
When dynamic, different states can occur in blind aobvious point 5.
Each driving motor 2 is connect with steering engine controller, and each steering engine controller electrically connects with CPU
It connects, the CPU is also electrically connected a SD card for storage file data.
The steering engine controller is PWM Shield for Arduino, and CPU is C8051F410 chips, the model of SD card
