Description

Portable writing auxiliary system

Technical Field

The present invention relates to an electronic writing assisting system, and more particularly, to a portable writing assisting system.

Background

With the continuous development of economy, the quality of life of people is greatly improved, and the meaning of life is continuously enriched. In daily life, there are many calligraphy enthusiasts who love practice and display of various calligraphy: some of them love traditional Chinese brush calligraphy, some love hard-tipped pen calligraphy, and some love flower-body English.

During the exercise of calligraphy, there are the following problems: firstly, beginners have inaccurate control on the space layout of characters, and written characters tend to be left or right and may also tend to be large or small; secondly, a method of manually drawing lines on the writable material can help a beginner to grasp the spatial layout, but the marks of the lines are left on the paper, so that the attractiveness is influenced; for the condition of various writing contents, the manual drawing process is complex, and the time cost is large; fourthly, drawing different line grids according to different writing contents, which wastes time and labor; line grid drawing is difficult to remove due to the fragile paper and the particularity of writing ink, or smearing and scratch of writing are caused in the removing process, and the attractiveness is seriously affected.

Disclosure of Invention

It is an object of the present invention to overcome the above-mentioned deficiencies of the prior art by providing a portable writing aid system.

The purpose of the invention can be realized by the following technical scheme:

the utility model provides a portable auxiliary system that writes, includes control module, singlechip circuit board, line check projection module and display module, control module, line check projection module and display module be connected with singlechip circuit board respectively, singlechip circuit board bluetooth module and power module have, line check projection module throw out the line check pattern that supplementary user wrote on the plane, display module show current line check pattern type, control module be used for switching line check pattern and adjusting line check luminance, bluetooth module and cell-phone link to each other the back, accept the control command who comes from cell-phone APP for switch line check pattern and with adjust line check luminance.

The line grid projection module comprises a laser module array.

The laser module array comprises a plurality of linear laser modules, and each module is arranged in a space with a set included angle.

The laser module array has different combinations of illumination, angles and line types under a plurality of preset modes.

The control module comprises an on/off button, a brightness adjusting button, a line grid switching button and a laser module array control button, wherein the laser module array control button comprises a plurality of buttons and is used for independently controlling the on and off of each laser module.

The brightness adjusting button comprises two buttons of brightness enhancement and brightness reduction.

The power module comprises a No. 5 battery and a DC/DC direct current conversion device.

The display module is a 0.96-inch OLED display screen.

The display module also displays the Bluetooth connection state and the line grid pattern type name.

Compared with the prior art, the invention has the following advantages:

(1) the auxiliary performance is superior. By adopting a projection mode, the drawn line grid pattern is adjustable, and compared with the traditional manual line grid drawing, the time consumption is greatly reduced; meanwhile, the laser irradiation method is adopted to avoid paper surface contamination, and the attractiveness is greatly improved.

(2) The laser module array comprises a plurality of linear laser modules, each module is arranged in a space at a set included angle, and the distance between the laser module and the plane is changed to adjust the size of the line grid.

(3) The brightness is adjustable. After a user presses a brightness adjusting button in the control module, the brightness adjustment of the line grid pattern can be realized: when the brightness enhancement button is pressed, the brightness of the line grid pattern is increased; when the brightness-decreasing button is pressed, the line grid pattern becomes less bright. The design is helpful for users to adjust the brightness of the line grid pattern according to writing occasions so as to achieve the effect of protecting vision.

(4) The pattern is rich. On one hand, after a user presses a line grid switching button, the selection of various preset line grid types can be realized; on the other hand, the laser module array control button in the control module can respectively and independently control the on and off of each laser module, and the user can design the line grid pattern according to own hobby. The flexible pattern design is more applicable to more extensive occasions and has good universality.

(6) The accessible bluetooth module is controlled, and the in-process that adjusts can be convenient observes the projection effect.
