Problems solved by technology

Such an interactive electronic whiteboard has high requirements on the application environment and poor environmental adaptability. When the same interactive electronic whiteboard is transferred to a different environment, the installation and positioning of the projector and the electronic whiteboard are more troublesome.
At the same time, this type of interactive electronic whiteboard can only ensure the clarity of the projected image by controlling the focal length of the projector, and it is difficult to continue to use it when the projection and focusing device fails

Embodiment Construction

[0034] In order to understand the technical content of the present invention more clearly, the following examples are given in detail.

[0035] see figure 1 As shown in FIG. 2 , it is a structural schematic diagram of the installation and positioning structure of the projector of the present invention.

[0036] In one embodiment, the projector installation and positioning structure includes a positioning beam 1, a projector mounting base 2 and a fixing base (not shown in the figure), wherein the positioning beam 1 is a beam, and the projector The assembly base 2 is movable and fixed on the beam 1 along the horizontal axis of the beam 1, the fixing base is connected to one end of the beam 1, and the projector installation and positioning structure is fixed on the beam 1 through the fixing base. On the external wall or on the bracket of external multimedia presentation equipment. Wherein, the beam 1 is provided with a chute 11 arranged along the horizontal axis of the beam, an...

Abstract

The invention relates to a projector installing positioning structure which comprises a positioning beam and a projector assembling base, wherein the projector assembling base is movably fixed on the positioning beam. By using the projector installing positioning structure, the connection position of the projector assembling base on the positioning beam can be conveniently adjusted. The invention also relates to an electronic whiteboard device equipped with the projector installing positioning structure. A motherboard device of the electronic whiteboard device comprises a projector and a whiteboard, wherein the projector is fixed on a bracket of the whiteboard through the projector installing positioning structure. By using the electronic whiteboard device, the relative position of the projector and the whiteboard can be flexibly moved so as to improve the adaptability of the device to an application environment. When a projector focusing device is in fault, a projected image can be kept clear just by adjusting a distance between the projector and the whiteboard, thereby preventing the training or meeting which applies the electronic whiteboard device from being interrupted under the influence of a damaged main input module.

Description

technical field [0001] The invention relates to the technical field of electronic education and teleconferencing systems, in particular to the technical field of electronic whiteboards, and specifically refers to a projector installation and positioning structure, an electronic whiteboard with the structure, and an interactive demonstration system. Background technique [0002] In modern society, people pay more and more attention to education, and at the same time, more and more facilities and funds are invested in education. However, in the traditional teaching listening mode, there is often one blackboard in one classroom, and the students sitting behind cannot clearly see the words on the blackboard, causing eye fatigue, easy to form myopia, and at the same time unable to take notes completely, so It will greatly affect the efficiency and quality of the lectures. [0003] With the development of electronic technology, electronic whiteboards have appeared in recent years...
