DETAILED DESCRIPTION

[0028] The specific embodiment of the utility model is further described in detail below in combination with the drawings, so that the technical scheme of the utility model is more easily understood and mastered.

[0029] A liquid crystal drawing book includes a cover 1, a back cover 2, a book spine 3 and inner pages 4. The two ends of the book spine 3 are respectively hinged to the cover 1 and the back cover 2. An installation board 8 is located on the side of the cover 1 facing the inner pages 4. An isolation page 5 is fixedly connected to the side of the installation board 8 opposite to the cover 1 by glue. The upper side of the inner pages 4 is fixedly connected to the isolation page 5 by glue, and the lower side of the inner pages 4 is fixedly connected to the back cover 2 by glue.

[0030] The installation board 8 is made of foam and has good buffering effect.

[0031] The side of the installation board 8 opposite to the isolation page 5 is provided with a handwriting liquid crystal screen 6 and a controller 9. The controller 9 includes a control assembly 10, a power supply 11 and a micro switch 12. The control assembly 10 includes a circuit board 13 and a chip 14. The chip 14 and the micro switch 12 are electrically connected to the circuit board 13, and the handwriting liquid crystal screen 6 is electrically connected to the circuit board 13 through a conductive mesh 26.

[0032] The first placing groove 15, the second placing groove 16 and the third placing groove 17 are formed on the mounting plate 8. The handwriting liquid crystal screen 6 is fixed in the first placing groove 15; the circuit board 13 is fixed in the second placing groove 16; and the power supply 11 is fixed in the third placing groove 17. The cross sections of the first placing groove 15 and the second placing groove 16 are square, and the cross section of the third placing groove 17 is circular. The power supply 11 is a button cell. The chip 14 and the micro switch 12 are respectively located on two sides of the circuit board 13, and the chip 14 is located on the side of the circuit board 13 facing the bottom wall of the second placing groove 16, so as to have a better protection effect on the chip 14.

[0033] The power supply 11 supplies power for the control assembly 10 and the handwriting liquid crystal screen 6.

[0034] Two circular positioning holes 18 are formed on the circuit board 13, and a positioning column 25 is connected to the button 19 and is embedded in the positioning hole 18.

[0035] The button 19 is made of silica gel, and the button 19 comprises a protruding part 20, an elastic ring 21 and a positioning part 22 which are integrally arranged. The two ends of the elastic ring 21 are respectively connected to the protruding part 20 and the positioning part 22. The protruding part 20 penetrates through the connecting hole 24, and the positioning column 25 is integrally connected to the positioning part 22. The connecting hole 24 is formed on the cover 1, and the cross section of the connecting hole 24 is circular.

[0036] The communicating window 23 corresponding to the handwriting liquid crystal screen 6 is formed on the cover 1.

[0037] A glue layer is coated on the side of the mounting plate 8 facing the cover 1, the glue layer is a non-dry glue layer, and the cover 1 is fixed to the mounting plate 8 through the glue layer.

[0038] The liquid crystal drawing book is divided into two stages of manufacturing and assembling process and user using process.

[0039] Manufacturing and assembling process:

[0040] Firstly, the book spine 3 is hinged at two ends of the cover 1 and the cover bottom 2, and a basic folding structure of the liquid crystal drawing book is built. Then, the mounting plate 8 is placed on the side of the cover 1 facing the inner page 4. On the side of the mounting plate 8 facing away from the cover 1, the isolation page 5 is firmly connected through glue, and the upper side of the inner page 4 is connected to the isolation page 5 through glue, and the lower side of the inner page 4 is connected to the cover bottom 2 through glue, so as to separate and fix the paper inner page 4 from the electronic assembly area.

[0041] On the side of the mounting plate 8 facing away from the isolation page 5, the installation of electronic components is carried out. The chip 14 and the micro switch 12 are electrically connected to the circuit board 13, forming a complete control assembly 10. Subsequently, the circuit board 13 is fixed into the second placement slot 16 on the mounting plate 8, the handwriting liquid crystal screen 6 is fixed into the first placement slot 15, and the button cell as the power supply 11 is fixed into the third placement slot 17. It is crucial that the handwriting liquid crystal screen 6 is electrically connected to the circuit board 13 through the conductive mesh 26, and this non-rigid connection provides a buffer space for subsequent use.

[0042] Finally, the positioning column 25 on the button 19 is embedded into the positioning hole 18 on the circuit board 13, ensuring accurate positioning of the button 19. The protruding part 20 of the button 19 passes through the circular connecting hole 24 on the cover 1 and is exposed for the user to press. On the side of the mounting plate 8 facing the cover 1, an adhesive layer is applied, and the cover 1 is fixed to the mounting plate 8 through the adhesive layer. At the same time, a communication window 23 corresponding to the handwriting liquid crystal screen 6 is opened on the cover 1, and thus the entire liquid crystal drawing book is assembled.

[0043] User usage process:

[0044] When children obtain the liquid crystal drawing book, they can open the cover 1 and the inner page 4 to draw on paper as with a traditional drawing book. When children want to make digital drawings on the cover 1, they can directly write or draw on the handwriting liquid crystal screen 6 through the communication window 23 on the cover 1.

[0045] When it is necessary to clear the content on the handwriting liquid crystal screen 6, the child only needs to press the button 19. The pressing action of the button 19 triggers the micro switch 12. After the micro switch 12 is triggered, it sends an electrical signal to the chip 14 on the circuit board 13. After the chip 14 receives the signal, it sends a clear instruction to the handwriting liquid crystal screen 6 through the conductive mesh 26, so that the content on the handwriting liquid crystal screen 6 is instantly erased, providing a blank interface for the next creation. During the entire operation process, the mounting plate 8 provides buffer protection for the internal components, and the non-rigid connection of the conductive mesh 26 ensures the stability of the handwriting liquid crystal screen 6 under pressure and vibration, and it is not easy to be damaged.

[0046] In addition, when the handwriting liquid crystal screen 6 and / or the power supply 11 need to be repaired or replaced, since the cover 1 is fixed to the mounting plate 8 by an adhesive layer, the cover 1 can be peeled off from the mounting plate 8 under a certain force, thereby exposing the internal handwriting liquid crystal screen 6 and other electronic components, facilitating maintenance operations.

[0047] Of course, the above is only a typical example of the present application, and in addition to this, the present application can have other various specific implementation manners, and any technical solution formed by equivalent replacement or equivalent transformation falls within the scope of protection required by the present application.
