Description
Technical field
The utility model is related to toy for children art, refers in particular to a kind of hand-written drawing board projecting apparatus.
Background technology
Traditional drawing can draw a picture in various material, for example：The materials such as paper, canvas, glass or timber, and draw a picture
Pigment or material can be comprising watercolor, ink, oil colour, charcoal pencils etc., but this traditional drawing is once drawn as, and just can not be repaiied
Change, the wasting of resources is made to a certain extent.
With the development of science and technology traditional drawing mode can not meet the demand of people, therefore slowly occur in that electronics
Drawing boards, which overcomes the drawbacks of traditional drawing can not be cleaned, and is especially suitable for younger ones in an age group children using as exercise drawing.But it is existing
Some electronic painting plates still suffer from the single defect of function.
Utility model content
In view of this, in view of the existing deficiencies of the prior art, its main purpose is to provide a kind of hand-written picture to the utility model
Plate projecting apparatus, can draw desired pattern, and show that color screen projects to wall or screen by LCD with paintbrush selection different colours
In.
To achieve the above object, the utility model is using following technical scheme：
A kind of hand-written drawing board projecting apparatus, including paintbrush input touch pad, paintbrush input touch pad electrical connection touch pad control
IC processed, touch pad control IC is electrically connected to central processing unit, the output end of central processing unit electrical connection projective LED lamp and
LCD shows color screen；When drawing desired pattern in paintbrush input touch pad selection different colours, the touch pad controls IC by pattern
Information is inputted to central processing unit, and central processing unit control projective LED lamp and LCD show color screen output, projected a pattern into white
Color wall or screen.
As a kind of preferred scheme, the input of the central processing unit is electrically connected with SD card Card Reader input interface, center
The output end of processor is electrically connected with audio output circuit module, when the SD card of be stored with pattern and music information inserts the SD card
Card Reader input interface, central processing unit reads the information of SD card, and control pattern-information projects to white wall or screen, music letter
Breath is synchronous to be played by audio output circuit module.
As a kind of preferred scheme, chargeable lithium cell built in the hand-written drawing board projecting apparatus, the lithium battery connects a USB
Charging inlet.
The utility model has clear advantage and beneficial effect compared with prior art, specifically, by above-mentioned technology
Scheme understands that it, which is mainly, is equipped with paintbrush input touch pad, touch pad control IC, central processing unit, projective LED lamp and LCD
Color screen is shown, the paintbrush that child can not only use paintbrush to input touch pad selection different colours is painted, and can be led to
Cross projective LED lamp and LCD shows that drawing is projected to wall or screen by color screen, show, both with interest, religion is taken into account again
The property learned.
More clearly to illustrate architectural feature of the present utility model and effect, come below in conjunction with the accompanying drawings with specific embodiment pair
The utility model is described in detail.
Brief description of the drawings
Fig. 1 is the structured flowchart of the hand-written drawing board projecting apparatus of the embodiment of the utility model.
Accompanying drawing identifier declaration：
1st, paintbrush input touch pad 2, touch pad control IC
3rd, central processing unit 4, projective LED lamp
5th, LCD shows color screen 6, SD card Card Reader input interface
7th, audio output circuit module 8, lithium battery
9th, USB charging inlets.
Embodiment
It refer to shown in Fig. 1, be a kind of hand-written picture that show the concrete structure of the preferred embodiment of the utility model
Plate projecting apparatus, its function of realizing mainly draws desired pattern with paintbrush selection different colours, and shows color screen by LCD
5 project in wall or screen.So, children can be used not only for drawing, moreover it is possible to come out picture display.
The hand-written drawing board projecting apparatus have a central processing unit 3, the central processing unit 3 as hand-written drawing board projecting apparatus core
The heart, for controlling LED display outputs, touch-screen input, SD information processings, audio files processing, projective LED control etc..
Specifically, the construction of the hand-written drawing board projecting apparatus includes paintbrush input touch pad 1, paintbrush input touch pad 1
Touch pad control IC 2 is electrically connected, touch pad control IC 2 is electrically connected to central processing unit 3, the output of the central processing unit 3
End electrical connection projective LED lamp 4 and LCD show color screen 5；Desired figure is drawn when inputting the selection different colours of touch pad 1 in paintbrush
Case, the touch pad controls IC 2 to input pattern-information to central processing unit 3, the control projective LED of central processing unit 3 lamp 4 and LCD
Display color screen 5 is exported, and projects a pattern into white wall or screen.
In addition, the input of the central processing unit 3 is electrically connected with SD card Card Reader input interface 6, central processing unit 3 it is defeated
Go out end and be electrically connected with audio output circuit module 7, when the SD card of be stored with pattern and music information inserts SD card Card Reader input
Interface 6, central processing unit 3 reads the information of SD card, and control pattern-information projects to white wall or screen, and music information is synchronous
Played by audio output circuit module 7.
And, chargeable lithium cell 8 built in the hand-written drawing board projecting apparatus, the lithium battery 8 connects a USB charging inlets 9,
When not enough power supply, by universal USB data line can opponent's Writing and drawing board projecting apparatus charged.
In summary, design focal point of the present utility model is, it, which is mainly, is equipped with paintbrush input touch pad 1, touches
Plate control IC 2, central processing unit 3, projective LED lamp 4 and LCD show color screen 5, and child can not only use paintbrush input to touch
The paintbrush of the selection different colours of template 1 is painted, and can show that color screen 5 projects drawing by projective LED lamp 4 and LCD
To wall or screen, show, both with interest, take into account again pedagogical.
It is described above, only it is preferred embodiment of the present utility model, not technical scope of the present utility model is made
Any limitation, therefore every any trickle amendment made according to technical spirit of the present utility model to above example, equivalent change
Change with modification, in the range of still falling within technical solutions of the utility model.
