detailed description

The structure schematic diagram of the present utility model is shown in Figure 1. The teaching multifunctional whiteboard of the present utility model includes a whiteboard installation frame, a whiteboard support plate, a whiteboard, a motor, a driving shaft, a driven shaft, and a wiping device. There is a whiteboard support plate, the driving shaft and the driven shaft are respectively installed on both sides of the whiteboard installation frame, and the driving shaft is connected to the output shaft of the motor, the whiteboard is supported on the whiteboard support plate, and one side of the whiteboard is rolled on the driving shaft, The other side is wound on the driven shaft, the driven shaft is equipped with a torsion spring, and the wiping device is mounted on the whiteboard installation frame. The whiteboard support plate 5 is used to bear the pressure of the whiteboard 6 when writing. The rotation of the driving shaft 2 and the rotation of the driven shaft 3 tighten the back surface of the whiteboard 6, and the friction between the driving shaft 2, the driven shaft 3 and the material of the whiteboard 6 provides power to realize the rotation of the whiteboard 6. For the convenience of installation, the whiteboard 6 can be made into a ring shape, which is sleeved between the driving shaft 2 and the driven shaft 3 .

In this embodiment, the above-mentioned driving shaft 2 is connected with the output shaft of the motor 7 through a coupling,

In this embodiment, the wiping device 4 includes a first wiping motor 9 and a first brush block 11 , and the first brush block 11 is connected to the output shaft of the first wiping motor 9 .

In this embodiment, the wiping device 4 further includes a second wiping motor 10 and a second brush block 12 , and the second brush block 12 is connected to the output shaft of the second wiping motor 10 .

In this embodiment, the rotation speed and rotation angle of the motor 7 are controlled by a single-chip microcomputer.

In this embodiment, the rotation speed and rotation angle of the above-mentioned first wiping motor 9 are controlled by a single-chip microcomputer.

In this embodiment, the rotation speed and rotation angle of the second wiping motor 10 are controlled by a single-chip microcomputer. Realize the adjustment of the forward and reverse of the whiteboard, and achieve functions such as updating the blank whiteboard and looking back after selective erasing.

The above-mentioned brush block changes the rotation angle of the brush block through the rotation of the motor, and then adjusts the distance between the brush block and the whiteboard to realize its erasing function. The left and right scrolling of the whiteboard can be realized by controlling the motor 7 . Because the driven shaft 3 is equipped with a torsion spring 8, when the driven shaft 3 is driven by the whiteboard 6 wound on it by the driving shaft 2, the torsion spring 8 is deformed, and a torsional force will be generated, which will make the whiteboard 6 in a tight state. state, when the motor 7 was powered off, the driving shaft 2 lost the torsional force, and the torsional force of the torsion spring 8 would make the whiteboard turn left.

The motor of the utility model drives the driving shaft to rotate through the transmission mechanism, thereby driving the driven shaft to rotate, and the driving shaft and the driven shaft rotate to tighten the back of the whiteboard, which is provided by the friction between the driving shaft, the driven shaft and the material of the whiteboard. The driving force realizes the rotation of the whiteboard, thereby realizing the update of the blank whiteboard, that is, when an area is filled with teaching content, the whiteboard can be rotated to make a blank area appear on the whiteboard facing us, and the rotation of the driving shaft can make the whiteboard rotate , and the look-back function can also be realized. In addition, the spring assembled on the driven shaft can keep the whiteboard in a tight state all the time, which can prevent the whiteboard from loosening due to long-term use. The brush block in the whiteboard wiping device can move back and forth under the drive of the rocker mechanism to achieve close contact and clutch with the whiteboard, and realize selective erasing; due to the long use time, it is inevitable to encounter the cleaning problem of the brush block , so the brush block and the rocker mechanism are detachable for easy cleaning and replacement. The above-mentioned whiteboard is a PVC material that can be used as a projection screen. The PVC material is soft, easy to write and erase, and easy to scroll. It is not easy to fail due to the transmission device, and it provides convenience and benefits for teaching.

The utility model can realize the integrated function of the ordinary blackboard and the projection screen, which can not only save space, but also bring benefits. Due to the adoption of the utility model, the existing traditional blackboard can be changed into a PVC panel that can be driven and rolled by a motor and a transmission mechanism, and is equipped with an automatic wiping device structure; Selective and easy to erase, review and project features. Greatly reduce the burden on the teacher, but also improve the efficiency of class.
