Description

Technical Field

[0001] The utility model relates to the technical field of multimedia, in particular to an anti-collision device for multimedia machines. Background Art

[0002] A multimedia machine is a computer device that can process multimedia information such as audio and video. It is widely used in the fields of office automation, computer-aided work, multimedia development, and education and publicity. For example, in the field of education, multimedia machines can be used to produce electronic courseware, interactive teaching, remote video conferencing, etc., to improve teaching effectiveness and learning experience.

[0003] During the use of multimedia machines, the part with the highest damage rate is usually the display screen, and the reasons for screen damage usually include:

[0004] External force impact: The multimedia machine may be subjected to accidental impact during use, such as students playing and fighting, which may cause the display screen to crack or be damaged.

[0005] Screen scratches: When a multimedia machine is in use, its screen may be scratched by sharp objects such as fingernails, manicures, and low-quality styluses. Over a long period of time, the screen breakage rate increases.

[0006] In the Chinese patent publication number CN212135681U, an English teaching device with dustproof and anti-collision functions is proposed; the outer shell can prevent the blackboard and the multimedia screen from being bumped. In addition, the dustproof cover and dustproof strips can also improve the dustproof efficiency, so that the device can be kept clean when not in use.

[0007] Although the above technical solution can prevent the blackboard and the multimedia screen from colliding, it still has some shortcomings in actual use; first, the above technical solution requires the multimedia screen to be rotated 180 degrees when the multimedia screen is folded and used. Generally, a desk is placed in front of the podium in the classroom. If the height of the desk is higher than the height difference between the multimedia screen and the podium, the multimedia screen will be blocked by the desk when it is rotated, and finally the multimedia screen cannot be rotated, and the use of multimedia is limited by the position of the desk; second, the above technical solution requires the multimedia screen to be attached to the blackboard when the multimedia is not in use. Since most of the blackboards have chalk dust, the multimedia screen is also stained with chalk dust after being attached to the blackboard, resulting in the multimedia screen needing to be cleaned every time it is used, which is very inconvenient; third, the above technical solution covers the blackboard and the multimedia at the same time through the shell when the multimedia is not in use, resulting in the blackboard being unable to be used alone; in addition, when only the blackboard is needed to be used, the staff must also rotate the multimedia screen 180 degrees to use the blackboard, which is the same as the operation process when using multimedia, which is very inconvenient.

[0008] As is known from the above, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content
