Referring to FIGS. 1-3 , an embodiment of the present invention proposes a smart blackboard, including a glass 1 , a front frame 2 , a middle frame 3 and a rear case 4 .

The glass 1 is bonded and fixed on the front surface of the front frame 2, and the glass 1 can be used for writing with chalk, and can also be used to protect the display panel inside the smart blackboard. The front frame 2 is used to fix the glass 1 and serves as a frame of the smart blackboard to protect internal components. The middle frame 3 is fixedly connected to the rear surface of the front frame 2, and the middle frame 3 is used for fixing and supporting components arranged inside the smart blackboard such as display panels, backlight modules, motherboard cards and the like. One or more buckles 30 are fixedly arranged on the rear surface of the middle frame 3 , and the rear shell 4 has a rear shell buckle structure 40 , which is fastened and fixed on the middle frame 3 through the buckles 30 .

In one embodiment, a plurality of buckles 30 are detachably fixed on the edge of the middle frame 3 , for example screwed, and evenly distributed on the edge of the middle frame 3 . Preferably, the buckle 30 is fixed on the middle frame 3 with two screws, and the buckle 30 is fixed on the middle frame 3 in a detachable manner, which is more maintainable and more convenient to maintain. When a buckle is damaged , just replace the damaged buckle directly.

The rear case 4 has one or more protrusions extending inwardly and protruding from the inner surface of the rear case 4 , and the protrusions constitute the buckle structure 40 of the rear case. The buckle structure 40 of the rear case is integrally formed with the rear case 4 . The buckle structure 40 of the rear case is provided corresponding to the buckle 30 . A first side of the rear shell buckle structure 40 is engaged with the buckle 30 , and a second side of the rear shell buckle structure 40 opposite to the first side forms a slope 41 . The buckle structure 40 of the rear case is spaced a certain distance d from the surface of the edge of the rear case 4, and the side of the edge of the rear case 4 close to the inner surface of the rear case 4 protrudes outward to form a flange 42, and the edge of the rear case 4 is stepped structure.

4a-4b, the buckle 30 includes a strip-shaped thin plate-shaped base 31, the first surface of the base 31 is provided with first longitudinal support parts perpendicular to the first surface of the base 31 and arranged at intervals. 32 .
