Detailed ways

Now in conjunction with accompanying drawing, the utility model is described in further detail. These drawings are all simplified schematic diagrams, and only schematically illustrate the basic structure of the utility model, so they only show the configurations related to the utility model.

As shown in Fig. 1, a kind of intelligent blackboard comprises a base plate 1 and a driving assembly 5 fixed on the base plate 1, a limit assembly, a wiping assembly and a writing assembly, and the writing assembly includes two driving shafts 2 arranged in parallel and from Drive shaft 14, the drive shaft 2 is in transmission connection with the drive assembly 5, the drive shaft 2 drives the driven shaft 14 to rotate, a writing board 3 is arranged between the driving shaft 2 and the driven shaft 14, and the writing board 3 moves up and down along the driving shaft 2 or the driven shaft 14, the writing board 3 is respectively connected with the driving shaft 2 and the driven shaft 14, and the wiping assembly includes a rolling eraser 9, a bracket 15 and a slider 8, the Rolling eraser 9 is fixed on the support 15 by slide block 8, and described limit assembly comprises two limit plates 7 that are arranged in parallel, is provided with leading screw 10 and slide plate 6 between two limit plates 7, and described lead screw 10 Through the slide plate 6 and the lead screw 10 is in transmission connection with the slide plate 6 , the drive assembly drives the slide block 8 to move along the bracket 15 through the lead screw 10 .

Specifically, the drive assembly 5 includes a motor, which is electrically connected to a wireless signal receiver; in fact, the motor drives the drive shaft 2 and the lead screw 10 to rotate through a worm gear.

Specifically, a first limit switch 11 is provided on one side of the support 15; in fact, the height of the first limit switch 11 is slightly higher than the board surface of the writing board 3, mainly to prevent the rolling eraser 9 from touching the writing board 3. Press too tightly between the boards and cause damage to the boards.

Specifically, the writing board 3 is a translucent flexible material.

Specifically, an LED lamp 4 is provided between the driving shaft 2 and the driven shaft 14. When the light is insufficient, turning on the LED lamp 4 can compensate for the light and prevent reflection on the surface of the writing board 3.

Specifically, the rolling eraser 9 includes a roller and a sponge or rag covered on the roller.

Specifically, the drive shaft 2 is connected to the driven shaft 14 through a chain 12 .

Specifically, one end of the bracket 15 is fixed on the base plate 1, and the other end of the bracket 15 is provided with a second limit switch 13. The second limit switch 13 is mainly used to limit the position of the rolling eraser 9 and prevent the slider 8 from going out. Bracket 15.

The working principle of the smart blackboard: the motor of the driving component 5 is controlled to rotate forward or reversely through the external remote control. When the motor drives the driving shaft 2 to rotate, the motor drives the screw 10 to rotate. Synchronously, the driving shaft 2 drives the driven shaft 14 rotates, so that the surface of the writing board 3 can move up and down, and during this movement, the slider 6 will also slide between the two limit plates 7 correspondingly, when the slider 6 moves along the lead screw 10 moves until it touches any one of the two limiting plates 7, the motor will stop rotating, and the writing board 3 will also stop moving, thereby realizing the replacement of the board surface of the writing board 3; in fact, the writing board 3 and the following The connection structure of the driving shaft 14 is similar to that between the drive belt and the drive wheel, mainly to make the writing board 3 move around the driven shaft 14 to make the board surface of the writing board 3 rise or fall.

When it is necessary to erase the written content on the writing board 3, you only need to press the external remote controller or switch to control the motor, and drive the screw 10 to make the slider 8 approach the writing board 3 along the bracket 15 until the eraser is rolled. 9 triggers the first limit switch 11 and stops moving. At this time, the rolling eraser 9 is attached to the board surface of the writing board 3, and the rolling of the rolling eraser 9 can erase the board surface of the writing board 3, which is very convenient. After erasing, control the scroll eraser 9 to return automatically until the scroll eraser 9 triggers the second limit switch 13 and stops.

The beneficial effect of the utility model is that the intelligent blackboard realizes the lifting control and automatic wiping of the blackboard through the external remote control, and uses a transparent plastic film to replace the original painted board surface, without using chalk for writing, ensuring the health of teachers and students , It can also replace the projection screen, which improves the utilization rate of the blackboard.

Inspired by the above ideal embodiment according to the utility model, through the above description content, relevant staff can completely make various changes and modifications within the scope of not deviating from the technical idea of the utility model. The technical scope of this utility model is not limited to the content in the description, but must be determined according to the scope of the claims.
