Description

A single-frame intelligent blackboard

technical field

The utility model relates to the technical field of teaching blackboards, in particular to a single-frame intelligent blackboard.

Background technique

With the trend of intelligent teaching tools, intelligent interactive blackboards have been popularized in most teaching environments. The classroom interactive blackboard uses a large-sized LCD screen in the process of design, production and use, and directly fixes it in the frame through connectors, and then forms a whole with the glass blackboard for teaching or various meetings.

At present, most of the smart blackboards used are to install and fix the glass blackboard and the display module separately. The display module often integrates the display board, optical film and backlight module, and connects with the glass blackboard frame as a whole. That is to say, the display module has a separate fixed frame, which is connected by a plurality of connectors distributed along its circumference, and then the frame is connected with the external glass blackboard fixing frame to realize the display module and the glass blackboard fixed between. For example, the Chinese patent (application number: 2016211463514) discloses a transparent capacitive touch ultra-high-definition electronic blackboard, which includes a fixed frame, a transparent glass cover and a touch all-in-one machine. Different frames are used between the liquid crystal module and the cover plate.

Chinese patent (application number: 2014205035549) discloses a touch whiteboard all-in-one machine, which is mainly composed of a casing, a host unit, a display unit, and a touch sensing unit. The casing can be composed of an outer frame and a glass blackboard inside the outer frame, or It is composed of the outer frame formed by the infrared touch sensing module and the embedded glass blackboard. Regardless of the form, it can be determined without a doubt that the outer frame and the display unit are set separately, that is, the display unit itself is connected and fixed with the glass blackboard as a whole through the frame.

The Chinese patent with the patent application number: 201611036535X discloses a frame structure of an interactive smart panel and an interactive smart panel. Its structure is similar to that of a smart blackboard, but it is different from the field of the blackboard. The material used for the frame structure and the installation process exist big difference. In addition, in this solution, two frames are still used to fix the components, and when applied to a glass blackboard, there are still no major defects.

After the research, analysis and exploration of the existing smart blackboards, the current scheme that the display module and the glass blackboard are fixed by their own frames and then connected can also be regarded as an integrated setting, and the frames can also be used as an integrated device through various fixed connections. It is a whole, but the overall structure is complex, so that the LCD screen itself cannot be well bonded to the frame, so that the difference and instability in production quality are caused, especially for large-sized LCD screens, the above situation is easy to cause The impact on its structural stability and display effect.
