[0019] Please see Figures 1 to 3 A rotatable and foldable smart blackboard includes a first mounting housing 1. Both the upper and lower ends of the first mounting housing 1 are provided with U-shaped grooves 3. Both U-shaped grooves 3 are rotatably connected to lead screws 4. Both lead screws 4 are threaded to the outer walls of the two lead screws 4. Support plates 6 are fixedly connected to the front end of the upper slider 5 and the rear end of the lower slider 5. Both support plates 6 are equipped with first motors 7 on their outer walls. The output ends of the two first motors 7 pass through the two support plates 6 and are fixedly connected to a second mounting housing 8.

[0020] In this embodiment: multiple smart blackboards are installed inside the first mounting housing 1 and two second mounting housings 8 respectively. When in use, the position of the first mounting housing 1 remains unchanged so that the person in the middle can see the content of the blackboard. The two first motors 7 can drive the two connected second mounting housings 8 to rotate, thereby adjusting the angle of the two second mounting housings 8 and rotating the blackboard inside the two second mounting housings 8 by a certain angle so that the people on both sides can also see the content of the blackboard more clearly.

[0021] When the blackboard is not in use, the lead screw 4 is rotated, thereby driving the two sliders 5 and the support plate 6 connected to the two lead screws 4 to move. The second mounting housing 8 at the right end is moved to the front of the first mounting housing 1, and the second mounting housing 8 at the left end is moved to the rear of the first mounting housing 1, so as to achieve the purpose of folding the multi-screen blackboard and taking up less space.

[0022] As a technical optimization of this utility model, the front end of the first mounting housing 1 has two vertically distributed rectangular slots 2. The interior of each of the two rectangular slots 2 is equipped with a second motor 11. The output ends of the two second motors 11 pass through the first mounting housing 1 and are respectively fixedly connected to two lead screws 4.

[0031] In this embodiment, the controller 14 is electrically connected to two first motors 7 and two second motors 11, and the operation of each component can be controlled by the controller 14.

[0032] Working principle: In use, multiple smart blackboards are first installed inside the first mounting housing 1 and two second mounting housings 8 respectively. Then, the mounting plate 10 is installed on the wall or the ground to support the first mounting housing 1 and the two second mounting housings 8. In use, the position of the first mounting housing 1 remains unchanged so that the person in the middle can see the content of the blackboard. The two first motors 7 can drive the two connected second mounting housings 8 to rotate, thereby adjusting the angle of the two second mounting housings 8 and rotating the blackboard inside the two second mounting housings 8 by a certain angle so that the people on both sides can also see the content of the blackboard more clearly.

[0033] When the blackboard is not in use, the two second motors 11 can drive the connected lead screws 4 to rotate, thereby driving the two sliders 5 and the support plate 6 connected to the two lead screws 4 to move. The second mounting housing 8 at the right end is moved to the front of the first mounting housing 1, and the second mounting housing 8 at the left end is moved to the rear of the first mounting housing 1, so as to achieve the purpose of folding the multi-screen blackboard and occupying less space.
