Description
Technical field
The present invention relates to Intelligent stationery technical field, specifically a kind of photosensitive smart pen.
Background technology
Pen is the big invention of the mankind, is the instrument for writing or drawing.By nib will with coloured solid or
Liquid is on paper or gas-solid surface rendering symbol or picture.
Do now and ball pen or free ink pen are most commonly used that in work, pen core can be changed, it is easy to carry.Common structure is
Pen core is fixed structure, is equipped with the cap for brush, the nib of pen core is protected；Or push type structure is used, by by tail of starting writing
So that pen core stretches out or retracted.But, often in use, user can forget nib is retracted or the cap for brush is covered, often
The cap for brush also easily comes off, and this is easy for the state for causing the nib of pen core to protect, if pen drops to ground or hair
It is raw to hit, nib, nib are easily damaged once damaging, and pen core just can not be used, and cause waste.
On the other hand, in writing process, the light and shade of ambient light can influence the fatigue conditions of the eyes of writer, if
Write for a long time under dim light, the problems such as eye fatigue, myopia can be caused.
The content of the invention
The present invention proposes a kind of photosensitive smart pen, solve the nib of pen core in the prior art can not obtain good protection,
And dim lights cause visual fatigue the problem of.
The technical proposal of the invention is realized in this way：
A kind of photosensitive smart pen, including penholder, the lower end of the penholder is provided with nib, and the upper end of the penholder is provided with tail
Lid；

State and driven tooth is provided with the madial wall of upper groove, the driven tooth is engaged with the drive gear；
The lower end of the moving block is provided with low groove, and the low groove is recessed upwards by the lower surface of the moving block；
Pen core is equipped with the inner chamber, the tail end of the pen core is placed in the low groove, the nib of the pen core
In the nib；
The lower end of the penholder is provided with thumb press area, the thumb press area and is provided with pressure sensor；
The pressure sensor is electrically connected with the control board, the control board and the battery, motor, light
Sensor and buzzer electrical connection；
Processor is provided with the control board, the processor receives the control that the pressure sensor is sent
Signal；When the control signal is to have turned to external pressure by becoming without external pressure, the processor is sent to the motor
Drive signal so that the motor is rotated forward so that it is outer that the nib of the pen core stretches out the nib；When the control signal is served as reasons
There is external pressure to become when turning to no external pressure, the processor sends drive signal to the motor so that the motor is anti-
Turn so that the nib of the pen core is retracted in the nib；
When the control signal for when having external pressure, the processor receives the light intensity letter that the optical sensor is sent
Number；When the light intensity signal is less than a certain setting value, the processor sends alarm signal, the buzzing to the buzzer
Device works.
Further, a fixed column is provided with the low groove, the top of the fixed column is fixed on the low groove
Top surface on, form gap between the side of the side of the fixed column and the low groove；
The tail end of the pen core is placed in the gap, and the fixed column is inserted in inside the tail end of the pen core.
Further, the line between the pressure sensor and the control board is embedded in the wall of the penholder
It is interior.
Further, fixed ring body is provided with the side wall of the inner chamber, the control board is arranged at the fixation
