Abstract

The invention discloses an auxiliary blackboard and an intelligent blackboard. The auxiliary blackboard is installed on the edge of the main screen. The auxiliary blackboard comprises a board body, a back board and a protection piece, the back board comprises a back board body and a supporting part, the supporting part is located on the edge of the back board body and is perpendicular to the back board body, the board body is installed at the end, away from the back board body, of the supporting part, and the protection piece covers the edge of the board body. The supporting part plays a role in supporting the plate body, and the situation that the plate body is bent can be reduced. As the plate body is manufactured by adopting a cutting and forming process method, the edge of the plate body is sharp. The protection piece wraps the sharp edge, and the situation that a user is cut can be reduced.

Description

technical field [0001] The invention relates to the technical field of liquid crystal interactive blackboards, in particular to a secondary blackboard and a smart blackboard. Background technique [0002] The smart blackboard generally consists of a main screen and a sub-blackboard, the main screen displays information, and the sub-blackboard is used for chalk writing. The existing secondary blackboard uses a varnished board as the writing surface. When making a varnished blackboard, the edge of the varnished board is usually bent to prevent the edge of the varnished board from cutting fingers. [0003] Since the varnished board is not wear-resistant, after a long time of writing, the varnished board will be damaged by friction. Therefore, enamel plates are used instead. However, due to the material and sintering characteristics of the enamel plate, it cannot be bent and can only be punched. The edge of the punched enamel board is sharp, which is easy to cut the user. ...
