Along with the vigorous development of education informatization, intelligent teaching equipment such as an intelligent blackboard and an interactive large screen gradually undertake the task of enabling informatization teaching to become more convenient and efficient. In the prior art, the intelligent blackboard comprises a blackboard main screen and two blackboard auxiliary screens, wherein the two blackboard auxiliary screens are respectively positioned at the sides of the blackboard main screen, the blackboard main screen is mainly used for electronic display and writing, and the blackboard auxiliary screens are used for writing. Two blackboard auxiliary screens and a blackboard main screen form a rectangular wisdom blackboard jointly, and four outer frames of wisdom blackboard are infrared touch frame, because two relative frame distances of the sky side of two blackboard auxiliary screens are far away to and two relative frame distances of ground side of two blackboard auxiliary screens are far away, meet under the circumstances such as the wall is not enough level, lead to blackboard main screen and blackboard auxiliary screen not on the coplanar easily, lead to writing the function broken string.

Fig. 2 is a schematic structural diagram of an intelligent blackboard provided in the embodiment of the present application; fig. 3 is a schematic structural diagram of the adjusting mechanism in fig. 2. Referring to fig. 2 and 3, the present application provides an intelligent blackboard including: the blackboard comprises a blackboard main screen 100, at least one blackboard auxiliary screen 200 and at least one adjusting mechanism 300, wherein at least one side of the blackboard main screen 100 is connected with the at least one blackboard auxiliary screen 200.

The adjusting mechanism 300 comprises an adjusting piece 310 and a first connecting component 320, the blackboard main screen 100 and the blackboard auxiliary screen 200 are both provided with a display surface and a back surface opposite to the display surface, the back surface of the blackboard main screen 100 and the back surface of the blackboard auxiliary screen 200 are connected through the first connecting component 320, the adjusting piece 310 is inserted into the first connecting component 320, one end of the adjusting piece 310 is abutted against the back surface of the blackboard auxiliary screen 200, and the adjusting piece 310 can push the blackboard auxiliary screen 200 to move so that the blackboard auxiliary screen 200 is parallel to the blackboard main screen 100.

In this application, blackboard main screen 100 and blackboard auxiliary screen 200 all can be used for showing and writing, and the wisdom blackboard can include a blackboard auxiliary screen 200, and a blackboard auxiliary screen 200 is located the side of blackboard, and the wisdom blackboard also can include two blackboard auxiliary screens 200, and two blackboard auxiliary screens 200 are located the relative both sides of blackboard mainboard respectively.

The adjusting mechanism 300 is used for adjusting the flatness between the blackboard main screen 100 and the blackboard auxiliary screen 200 to ensure that the display surface of the blackboard auxiliary screen 200 and the display surface of the blackboard main board are positioned on the same plane. The number of the adjusting mechanisms 300 is set corresponding to the number of the blackboard sub-screens 200 to adjust the flatness between the blackboard main screen 100 and each blackboard sub-screen 200, respectively.

Specifically, the adjusting mechanism 300 comprises an adjusting part 310 and a first connecting component 320, the blackboard main screen 100 and the blackboard auxiliary screen 200 are connected together through the first connecting component 320, the adjusting part 310 is inserted into the first connecting component 320, one end of the adjusting part 310 abuts against the back of the blackboard auxiliary screen 200, the other end of the adjusting part 310 is a handheld adjusting end, after the blackboard main screen 100 and the blackboard auxiliary screen 200 are installed on a support or an installation surface, the flatness of the blackboard main screen 100 and the blackboard auxiliary screen 200 is measured through a measuring instrument, when the error of the flatness is measured to be large, the adjusting part 310 can be manually adjusted to enable the adjusting part 310 to push the blackboard auxiliary screen 200 to move, and therefore the blackboard auxiliary screen 200 is parallel to the blackboard main screen 100. For example, when the blackboard sub-screen 200 protrudes toward the display surface with respect to the blackboard main screen 100, the blackboard sub-screen 200 is pushed by the adjusting member 310 to move away from the display surface so that the blackboard sub-screen 200 and the blackboard main screen 100 are parallel.

Alternatively, when the blackboard sub-screen 200 is depressed toward the back with respect to the blackboard main screen 100, the blackboard sub-screen 200 is pushed by the adjusting member 310 to move toward the display surface so that the blackboard sub-screen 200 and the blackboard main screen 100 are parallel. The adjusting piece 310 is simple and convenient to adjust, and the moving amount of the blackboard auxiliary screen 200 can be accurately controlled by controlling the pushing amount of the adjusting piece 310, so that the flatness adjustment of the blackboard main screen 100 and the blackboard auxiliary screen 200 can be accurately controlled, and the adjusting precision is high.

The intelligent blackboard provided by the embodiment of the application is used for displaying and writing by arranging the blackboard main screen 100 and the blackboard auxiliary screen 200, is used for adjusting the flatness between the blackboard main screen 100 and the blackboard auxiliary screen 200 by arranging the adjusting mechanism 300, the adjusting mechanism 300 is used for connecting the blackboard main screen 100 and the blackboard auxiliary screen 200 by arranging the first connecting component 320, is inserted into the first connecting component 320 by arranging the adjusting piece 310, and enables one end of the adjusting piece 310 to be abutted against the back of the blackboard auxiliary screen 200, thereby pushing the blackboard auxiliary screen 200 to move relative to the blackboard main screen 100 by the adjusting piece 310, and enabling the blackboard auxiliary screen 200 to be parallel to the blackboard main screen 100.

In one possible implementation, the adjusting member 310 is threadedly coupled to the first coupling member 320, and the adjusting member 310 is rotated relative to the first coupling member 320 to move the blackboard sub-screen 200.

Thus, by screwing the adjusting member 310 to the first coupling member 320, when the adjusting member 310 is adjusted, the adjusting member 310 can be rotated with respect to the first coupling member 320 by twisting the hand-held adjusting end of the adjusting member 310, and the adjusting member 310 can be moved in the axial direction of the adjusting member 310, thereby moving the blackboard sub-screen 200 with respect to the blackboard main screen 100.

For example, the adjusting member 310 and the first connecting member 320 are connected by a right-handed screw, and when the blackboard sub-screen 200 protrudes toward the display surface relative to the blackboard main screen 100, the hand-held adjusting end of the adjusting member 310 is rotated counterclockwise, so that the adjusting member 310 drives the blackboard sub-screen 200 to move away from the display surface, so that the blackboard sub-screen 200 and the blackboard main screen 100 are parallel. When the blackboard sub-screen 200 is depressed toward the rear with respect to the blackboard main screen 100, the hand-held adjustment end of the adjustment member 310 is rotated in a clockwise direction to push the blackboard sub-screen 200 to move toward the display surface, so that the blackboard sub-screen 200 and the blackboard main screen 100 are parallel. It can be understood that by screw-coupling the adjusting member 310 and the first coupling member 320, the pushing amount of the adjusting member 310 can be controlled by precisely controlling the number of rotations of the adjusting member 310, thereby precisely adjusting the moving amount of the blackboard sub-screen 200 with respect to the blackboard main screen 100.

And when adjusting, adjusting part 310 only need rotate, remove for first connecting element 320 to promote blackboard auxiliary screen 200 to remove, for prior art, need not constantly insert repeatedly in each regulation hole adjusting part 310 and establish and screw up, and it is more simple and convenient to adjust.
