In order to solve the technical problem, the utility model discloses a technical scheme is: a large-breadth blackboard for modern teaching comprises an electronic main board and writing side boards which are respectively arranged on a frame, wherein the two writing side boards are respectively arranged on the left side and the right side of the electronic main board;

write the curb plate and further include the aluminium sheet layer, the layer of writing of coating on the surface of aluminium sheet layer, another of aluminium sheet layer is connected with an at least aluminium strip on the surface, aluminium strip and aluminium sheet layer bonding connection, aluminium strip back of the body aluminium sheet layer on the surface spaced apart have a plurality of be used for installing the mounting hole of electron device.

The further improved scheme in the technical scheme is as follows:

1. in the above scheme, the electronic main board is an electronic whiteboard, a touch display board or a touch writing board.

2. In the scheme, the aluminum strips are connected with the aluminum plate layer in a bonding mode through the heat conducting glue layer.

3. In the above scheme, the number of the aluminum strips is 4.

4. In the scheme, the 4 aluminum strips are connected end to end and are arranged into a rectangle.

5. In the scheme, the thickness ratio of the aluminum strips to the aluminum plate layer is 1.

6. In the scheme, the thickness of the aluminum plate layer is 0.5 cm-1.5 cm.

Because of above-mentioned technical scheme's application, compared with the prior art, the utility model have the following advantage:

the utility model discloses modern teaching is with big breadth blackboard, it is when melting traditional blackboard concurrently and write and modern multimedia teaching requirement, and it writes the curb plate and further includes the aluminium sheet layer, the layer is write to a coating on the surface on aluminium sheet layer, another on the aluminium sheet layer is connected with an at least aluminium strip on the surface, aluminium strip and aluminium sheet layer bonding connection, aluminium strip back of the body aluminium sheet layer on the surface interval open have a plurality of be used for installing the mounting hole of electron device, both practiced thrift the cost, alleviateed weight, good structural stability and intensity have again, still can provide good installation and radiating environment for the electron device that generates heat on the electronic motherboard, prolong holistic life.
