Embodiment Construction

[0033] see Figure 1 to Figure 4 , an electronic whiteboard, which includes a board surface 1, four frames 2, and four corners 3.

[0034] The board surface 1 is a rectangle, which includes a writable pre-coat layer 11 on the top layer, a foam layer 13 on the middle layer, and a back plate 15 on the bottom layer.

[0035] The foam layer 13 is a layer of XPS high-strength foam board.

[0036] The back plate 15 is a layer of galvanized steel plate.

[0037] A row of several square holes 151 are formed around the edge of the back plate 15 .

[0038] Between the writable pre-coat layer 11 and the foam layer 13 , and between the foam layer 13 and the back plate 15 are firmly bonded with glue.

[0039] It needs to be pointed out again that although the present invention is called an electronic whiteboard, the color of the board surface 1 and the surface of the writable pre-coat layer 11 is not limited, it can be white or black, or gray, pink, light green Wait, this kind of elect...

Abstract

The invention discloses an electronic whiteboard. The whiteboard comprises a board surface, four frames and four corners, wherein the board surface comprises a precoated layer which can be written, a foaming layer and a backboard; each frame comprises a frame body and a plurality of stopping and blocking fixture blocks, wherein the frame body comprises a top cover board, a light filter board, an upper baffle and a side baffle, and the light filter board is welded and connected between the top cover board and the upper baffle to form a whole; the side baffle is perpendicularly extended outwards, and a fixed inserting board is arranged on the side baffle; the rear end of the fixed inserting board is perpendicularly extended downward, and a locking board is arranged on the fixed inserting board; the stopping and blocking fixture blocks are mounted at the lower end of the locking board, each stopping and blocking fixture block comprises a snap-in part, and a stopping and blocking part is arranged at the lower end of the snap-in part; each corner comprises a corner lower cover and a corner upper cover, wherein the corner lower cover comprises a lower cover body, the corner upper cover comprises an upper cover body, the outside of the upper cover body is bended and extended downward, a side board is arranged on the upper cover body, and a sealing strip is arranged at the contact position of the precoated layer and the inner side edge of the upper cover body. The electronic whiteboard disclosed by the invention has the advantages that the structure is steady, the whiteboard is indeformable under the service environment, the waterproof function is good, and the use is safe.

Description

technical field [0001] The invention relates to an electronic whiteboard which can be widely used in classrooms and can replace traditional blackboards. Background technique [0002] At present, in many classrooms, blackboards are still used, all of which must be written with chalk, and the dust is flying, which seriously affects the health of teachers and students, and the writing speed is slow and the teaching efficiency is low. [0003] In some classrooms, the mode of "electronic whiteboard + traditional blackboard" is adopted. The electronic whiteboard is overlapped on the blackboard or adopts a sliding door type, and the electronic whiteboard is hidden in the sliding door. The clean and tidy environment also left a safety hazard. Aluminum profiles are used as the frame and aluminum injection parts are used as the corners. In addition to being bulky, material-consuming, not energy-saving, and not low-carbon, the biggest weakness is that it is not waterproof and unsafe. ...
