[0017] like Figure 1 and Figure 3 As shown, a portable drawing board for teaching advanced mathematics includes a first shell 1 and a second shell 11, the first shell 1 is rotatably connected to the second shell 11, a touch screen 2 is installed on the first shell 1, a wireless communication module 6 and a voice control module 7 are installed on the first shell 1, a first magnetic block 3 is provided at both ends of one side of the first shell 1, a handwriting board 14 is installed in the inner cavity of the second shell 11, a whiteboard layer 8 is provided on the outside of the handwriting board 14, the handwriting board 14 is located in the whiteboard layer 8 and is in contact with the inner upper end of the whiteboard layer 8, rollers 15 are provided on both sides of the inner cavity of the whiteboard layer 8, the rear roller 15 is rotatably connected to the inner cavity of the second shell 11, and one end of the front roller 15 is in contact with the second shell 11 inner cavity rotation connection, the other end is provided with a micro motor 17, and is connected to the output end of the micro motor 17, a cleaning brush 16 is provided on one side of the rear roller 15, and the cleaning brush 16 is installed in the inner cavity of the second shell 11, and the cleaning brush 16 is in contact with the surface of the whiteboard layer 8. A second magnetic block 4 is provided on both the front and back sides of one side of the second shell 11. The touch display screen 2 is connected to the handwriting board 14 through a connecting line 5. The touch display screen 2 has a built-in control module and a storage module. The control module integrates a high-performance processor and a special drawing software storage module for storing drawing data and teaching materials. The first magnetic block 3 cooperates with the second magnetic block 4 to call data, making teaching more convenient and the image more accurate.
[0018] The second shell 11 is provided with a groove 9, in which a whiteboard pen 10 is provided. The second shell 11 is also provided with a control button 20, a battery 18 is provided in the second shell 11, and a charging port 19 is provided on one side of the second shell 11 to prevent the whiteboard pen from being lost.
[0019] A third magnetic block 12 and a fourth magnetic block 13 are respectively provided on the left side of the first shell 1 and the second shell 11. The third magnetic block 12 and the fourth magnetic block 13 cooperate with each other, making it more stable during use. The first shell 1 and the second shell 11 are made of lightweight and high-strength composite materials. The wireless communication module 6 integrates Wi-Fi and Bluetooth modules, supports wireless connection with computers, projectors, mobile devices, etc., making the device more convenient to carry.
[0020] like Figure 1 As shown, when in use, when the drawing board is not needed, the first shell 1 and the second shell 11 are folded along the rotating connection part, and the first magnetic block 3 and the second magnetic block 4 attract each other and fit tightly to prevent the drawing board from opening accidentally. Since the first shell 1 and the second shell 11 are made of lightweight and high-strength composite materials, the overall weight is light, which is convenient for teachers to carry to different teaching places. When drawing is needed, the teacher unfolds the first shell 1 and the second shell 11, and the third magnetic block 12 and the fourth magnetic block 13 attract each other, making the first shell 1 and the second shell 11 more stable. The teacher can directly draw on the first shell 1 The touch screen 2 of the body 1 is operated, and the built-in drawing software is opened with a stylus or finger. The software integrates a high-performance processor and has a fast response speed. When explaining advanced mathematical functions, click the function input box in the software and enter the function expression. The drawing board can quickly draw an accurate function graph. The display ratio and angle of the image can also be adjusted by two-finger zooming, rotating, etc., which is convenient for students to observe. After the voice control module 7 is added, the teacher does not need to manually operate the touch screen 2. Just speak the voice command and the drawing board will automatically recognize and execute the corresponding drawing operation, which greatly improves the drawing efficiency. During the teaching process, teachers are more focused on explaining the content. If teachers are accustomed to the traditional handwriting and drawing method, they can use a whiteboard pen 10 to write and draw on the whiteboard layer 8. The whiteboard pen 10 is placed in the groove 9, which is easy to take and not easy to lose. The handwriting board 14 is located in the whiteboard layer 8 and contacts the upper end of the inner side of the whiteboard layer 8. The written and drawn content can be synchronously transmitted to the touch screen 2 through the connecting line 5, realizing the digital storage and display of the handwritten content. Through the Wi-Fi and Bluetooth functions of the wireless communication module 6, the drawing board can be connected to a computer, projector, mobile device, etc. to project the content on the drawing board To the projector, it is convenient for the whole class to watch; or the information can be sent to the students' mobile devices via Bluetooth, which is convenient for students to review after class. When the whiteboard layer 8 has been used for a period of time, there will be writing marks on the surface. Press the control button 20 on the second shell 11 to start the micro motor 17. The micro motor 17 drives the front roller 15 to rotate, thereby driving the whiteboard layer 8 to move. The cleaning brush 16 on one side of the rear roller 15 contacts the surface of the whiteboard layer 8. When the whiteboard layer 8 moves, the cleaning brush 16 automatically cleans the marks on the whiteboard, keeping the whiteboard tidy and convenient for next use. The battery 18 is charged through the charging port 19.
[0021] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
