Abstract
The invention provides an improved electromagnetic induction type electronic whiteboard which aims to solve the problem that an electromagnetic induction type electronic whiteboard is easy to interfere by external electromagnetism and deformation of the electronic whiteboard is caused by the hot and cold change of the environment. The body of the whiteboard is divided into three layers; an upper layer is a hard panel with high density; an intermediate layer is an electromagnetic induction prevention plate core; a lower layer is a high-strength compound plate. According to the electromagnetic induction type electronic whiteboard provided by the invention, a new material and a technology are adopted, so that the separation of a circuit board from the whiteboard is realized, the electromagnetic interference is prevented, the hot and cold impacts are resisted, the production and maintenance are convenient, and the stability in use of the whiteboard is improved, and the service life of the whiteboard is prolonged.
Description
Technical field
The present invention relates to the information education field, relate in particular to the induction electronic whiteboard of a kind of improvement.
Background technology
Along with popularizing of electronic whiteboard, there is plate miscellaneous in teaching and commercial the interchange, but induction electronic whiteboard is subject to external electromagnetic interference, the cold and hot variation of environment also can cause the plate distortion, also have not wear-resisting, reflective, dazzling, watch for a long time the shortcomings such as eyes tire easily, the present invention is and addresses this problem.
Summary of the invention
The present invention relates to the induction electronic whiteboard of a kind of improvement, main body comprises three layers, and the upper strata is that high-density hard panel, middle anti-interference compoboard core, lower floor are high-strength composite board, adopts bi-component to solidify glue between three ply board and fixes.
Pcb board is not set around the described blank, and the blank lead-in wire places in the PCB box, and the PCB box is arranged at one jiao of blank, and the netting twine of electronic whiteboard separates with the pcb board box.
Described electronic whiteboard frame adopts the combination of PVC+ iron plate.
Beneficial effect of the present invention is: netting twine separates with the pcb board box..Without pcb board, lead-in wire is received in the PCB box all around around the plate, and convenient production and maintenance reduced and produced and maintenance cost.The blank main body adopts three-decker, and the high-density hard panel is adopted on the upper strata, through surface treatment, reaches wear-resisting, and is not reflective, not dazzling, watches for a long time an indefatigability.Anti-interference compoboard core is adopted in the middle level, improves the interference free performance of blank.Lower floor adopts high-strength composite board, when increasing blank intensity, improves the blank interference free performance.Adopt bi-component to solidify glue between three ply board and fix, improve the problem that causes the blank distortion because of the cold and hot variation of environment.Frame adopts the combination of high-quality PVC+ iron plate, improves the intensity of product, reduces the blank distortion.
Described content only is the basic explanation of the present invention under conceiving, and according to any equivalent transformation that technical scheme of the present invention is done, all should belong to protection scope of the present invention.
