Abstract

The utility model provides a can obtain the interactive whiteboard that the user touched the position fast, including framework and optical image module, the framework including the aviation aluminium honeycomb panel that is the square with set up at the aviation aluminium honeycomb panel support of three edges wherein, the optical image module is including setting up LED infrared light source and the CCD optical sensor at another limit both ends of aviation aluminium honeycomb panel to and attached reflective membrane on the support, one side cover that aviation aluminium honeycomb panel is close to the optical image module has inferior light coating, and the marginal cladding of framework has the plastics frame, and the lateral wall of plastics frame is equipped with hangs a wall installed part.

Description

A kind of interactive electric whiteboard

Technical field

The utility model relates to a kind of electronic whiteboard, is specifically related to a kind of interactive electric whiteboard.

Background technology

Electronic whiteboard be a kind of by with computing machine and projector with the use of, realize the instrument of non-support cable and teaching.Its advantage is that Faculty and Students can directly operate document and software by special pens on blank, and keyboard need not be used just can to write on screen and paint mark, very convenient and directly perceived.

Current interactive electric whiteboard mainly contains following several: 1, pressure-sensitive electronic whiteboard, and this electronic whiteboard uses, and it is relatively more painstaking to write, and even cannot show writing, and reaction velocity is slow when pressure is inadequate; 2, ultrasonic type electronic whiteboard, volume ratio is comparatively large, be not suitable for meticulous writing, and service range is restricted; 3, induction electronic whiteboard, must use special pens just can write, can not do touch operation, and middle once scratch, then monoblock electronic whiteboard all can not employ.

Summary of the invention

The purpose of this utility model provides a kind of interactive electronic white board that can obtain user touch location fast to overcome above-mentioned the deficiencies in the prior art.

The interactive electric whiteboard that the utility model provides, comprises framework and optical image module; Framework to comprise in tetragonal aviation aluminum honeycomb panel and is arranged on the support of aviation aluminum honeycomb panel wherein on three limits, optical image module comprises the LED infrared light supply and CCD optical sensor that are arranged on another two ends, limit of aviation aluminum honeycomb panel, and is attached to the reflective membrane on support; Aviation aluminum honeycomb panel is coated with sub-light coating near the side of optical image module, and the edge of described framework is coated with plastic frame, and the sidewall of plastic frame is provided with hangs wall fabricated section.

The interactive electric whiteboard that the utility model provides, LED infrared light supply launches Infrared irradiation on reflective membrane, Guang Yuan road is fed back into the CCD optical sensor at LED infrared light supply place by reflective membrane, when whiteboard surface a bit has opaque materials to touch the light that will block and be launched by light source, CCD optical sensor does not just receive the light of reflective membrane reflection, the controller of electronic whiteboard detects through complicated calculating the coordinate figure that opaque materials touches, and sends into computing machine through USB interface.

Accompanying drawing explanation

In order to the technical scheme in clearer explanation the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described, apparent, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.

Fig. 1 is the front elevation of interactive electric whiteboard;

Fig. 2 is the rear view of interactive electric whiteboard;

Fig. 3 is interactive electric whiteboard exploded view.

Below the parts title in above-mentioned accompanying drawing corresponding to Reference numeral: framework 10, aviation aluminum honeycomb panel 11, subsides reflective membrane support 12, optical image module 20, LED infrared light supply 21, CCD optical sensor 22, reflective membrane 23, sub-light coating 30, plastic frame 31, extension wall fabricated section 32.

Embodiment

As shown in Figure 1,2 and 3, the interactive electric whiteboard that the present embodiment provides, comprises framework 10 and optical image module 20; Framework 10 to comprise in tetragonal aviation aluminum honeycomb panel 11 and be arranged on the support 12 of aviation aluminum honeycomb panel 11 wherein on three limits, optical image module 20 comprises the LED infrared light supply 21 and CCD optical sensor 22 that are arranged on another two ends, limit of aviation aluminum honeycomb panel 11, and is attached to the reflective membrane (23) on support 12.

Aviation aluminum honeycomb panel 11 is coated with sub-light coating 30 near the side of optical image module 20, and the edge of framework 10 is coated with plastic frame 31, and the sidewall of plastic frame 31 is provided with hangs wall fabricated section 32.

The interactive electric whiteboard that the present embodiment provides, LED infrared light supply launches Infrared irradiation on reflective membrane, Guang Yuan road is fed back into the CCD optical sensor at LED infrared light supply place by reflective membrane, when whiteboard surface a bit has opaque materials to touch the light that will block and be launched by light source, CCD optical sensor does not just receive the light of reflective membrane reflection, the controller of electronic whiteboard detects through complicated calculating the coordinate figure that opaque materials touches, and sends into computing machine through USB interface.

Apply specific case herein to set forth principle of the present utility model and embodiment, the explanation of above embodiment just understands method of the present utility model and core concept thereof for helping; Meanwhile, for one of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model.
