Projection device for digital media playing capable of being covered and conveniently adjusted inclined angle

Abstract

The invention discloses a projection device for digital media playing capable of being covered and conveniently adjusted an inclined angle. The device comprises a protective shell, an infrared receiver, a sliding base and a top plate, wherein a projector is arranged inside the protective shell, buffer supporting legs are installed below the projector, a through hole is formed in the upper surfaceof the protective shell, and a first driving motor is installed on the front end surface of the protective shell; a transmission gear is installed at the tail end of the first driving motor, the infrared receiver is arranged on the outer side of a dustproof baffle, a bearing frame is installed above the protective shell, a third driving motor is installed below the top plate, and the third drivingmotor is connected with the bearing frame through a rotating shaft in the lower part. The projection device for digital media playing capable of being covered and conveniently adjusted the inclined angle is provided with the infrared receiver, the two driving motors are started through the infrared receiver, so that the adjustment of the whole rotation for controlling can be facilitated, and thecontrol can be carried out remotely, and the use is convenient.

Description

technical field [0001] The invention relates to the technical field of digital media, in particular to a coverable projection device for playing digital media which is convenient for adjusting the tilt angle. Background technique [0002] Digital media refers to information carriers that record, process, disseminate, and obtain processes in the form of binary numbers. These carriers include digitized text, graphics, images, sounds, video images, and animations and other sensory media, as well as expressive media that represent these sensory media. Or coding, etc., commonly known as logical media, and physical media that store, transmit, and display logical media. [0003] When displaying digital media, it is necessary to use a projector for projection. In many usage occasions, the projector is hung on the ceiling. When changing the angle, people need to step on the table to adjust the change, which is inconvenient to operate and cannot adjust the projection lamp. Cover it u...
