Infrared touch screen frame structure, infrared touch screen and intelligent blackboard

Abstract

The invention discloses an infrared touch screen frame structure, an infrared touch screen and an intelligent blackboard, and belongs to the technical field of teaching equipment. An upper frame and side frames of the infrared touch screen frame structure are connected through upper corner braces, and a lower frame and the side frames of the infrared touch screen frame structure are connected through lower corner braces. Lamp strip grooves, light filter strip grooves and glass board grooves are formed in the upper frame, the lower frame and the side frames, and the light filter strip grooves are located in the outer sides of the lamp strip grooves. When lamp strips and light filter strips are overhauled or replaced, it is only needed to detach the corresponding frames and the corner braceson the two sides of the frames and then pull out the lamp strips and the light filter strips in the frames, and the overhaul and replacement efficiency is greatly improved. According to the infraredtouch screen and the intelligent blackboard, no edge joint is generated between the infrared touch screen and a writing board, the portion between the board surface of a glass board of the infrared touch screen and the board surface of the writing board is flat, and use is convenient.

Description

technical field [0001] The present invention relates to the technical field of infrared touch display devices, and more specifically, to an infrared touch screen frame structure, an infrared touch screen and a smart blackboard. Background technique [0002] With the increasing popularity and attention of electronic intelligent products, the education industry is also undergoing in-depth technological changes. Under the influence of the trend of intelligent teaching tools, smart blackboards have been popularized in most teaching environments and have gradually emerged. During the design, production and use of smart blackboards, a large-size touch display device is generally used as the main screen, and two writing pads are set as secondary screens on both sides of the main screen. Large-sized touch display devices generally include capacitive touch screens and infrared touch screens. [0003] Among them, when assembling a separate screen, after the frame is installed, the g...
