Embodiment Construction

[0025] The present invention will be further described in the following embodiments in conjunction with the accompanying drawings.

[0026] like Figure 1 to Figure 6 As shown, a front-maintenance infrared electronic whiteboard includes a whiteboard body 1 and four frames 2 installed on the edge of the whiteboard body 1. The frame 2 is made of an aluminum alloy extrusion die, and its surface can be made Powder coated, oxidized or brushed.

[0027] Each frame 2 is provided with a first card slot 21 and a second card slot 22 , and the first card slot 21 is located at the rear end of the second card slot 22 for fitting the whiteboard body 1 . In order to prevent the whiteboard body 1 from loosening, the inner wall of the first locking slot 21 is provided with a plurality of tooth-shaped locking positions 211 for restricting the whiteboard body 1 . A PCB fixing strip 3 is set inside the second card slot 22 , and an infrared PCB circuit board 4 and a filter strip 5 are fixed on t...

Abstract

The invention relates to a front-maintenance type infrared electronic whiteboard. The front-maintenance type infrared electronic whiteboard comprises a whiteboard body and four frames arranged on the edges of the whiteboard body. Each frame is provided with first clamping grooves and second clamping grooves. The first clamping grooves are used for allowing the whiteboard body to be sleeved with the frames. PCB fixing strips are arranged in the second clamping grooves in a sleeved mode. An infrared PCB circuit board and light filtering strips are fixed to the PCB fixing strips. The ends of every two adjacent frames are connected through a corner part. The two ends of the corner parts are fixedly connected with the ends of the corresponding frames through screws. The two ends of corner parts are further fixedly connected with the PCB fixing strips through screws. A front protection corner and a rear protection corner are wrapped on the front side and the rear side of each corner part respectively, wherein the rear protection corner is provided with at least one locating column which penetrates through a preformed through hole in one corner part and is connected with the front protection corner through screws. According to the front-maintenance type infrared electronic whiteboard, a firm and reliable connecting structure is provided, and consequently the front-maintenance type infrared electronic whiteboard is not to be prone to loosening in the using process, high in safety performance, long in service life, convenient to disassemble, assemble and maintain and attractive in appearance.

Description

technical field [0001] The invention relates to an electronic whiteboard, in particular to a front-maintenance infrared electronic whiteboard used for human-computer interaction input information in teaching and training. Background technique [0002] Infrared electronic whiteboard is the most suitable tool for teaching, meeting and other occasions. It can communicate with the computer, connect the electronic whiteboard to the PC, and use the projector to project the content on the PC to the electronic whiteboard screen. With the support of specialized applications, a large-screen, interactive collaborative meeting or teaching environment can be constructed. Use a specific positioning pen instead of the mouse to operate on the whiteboard, run any application, edit, annotate, save files, and any operations that can be achieved with the keyboard and mouse on the computer. [0003] At present, the infrared electronic whiteboards of the prior art have the following deficiencies...
