Wired screen projector capable of realizing remote control and all-round rotation and screen projection method

Abstract

Disclosed is a wired screen projector capable of realizing remote control and all-round rotation. The wired screen projector comprises a base, a bottom box is fixedly connected to the top of the base,an upper box is rotatably arranged at the top of the bottom box, an inner flange is fixedly connected to the inner side of the top end of the bottom box, and a plurality of arc-shaped clamping piecesis arranged on the circumference of the bottom of the upper box; the bottom ends of the arc-shaped clamping pieces extend to the bottom of the inner flange, protrusions are fixedly connected to the outer sides of the bottom ends of the arc-shaped clamping pieces, a screen projection processing module is fixedly installed in the bottom box, and a data interface and a power interface are formed inthe two ends of the bottom box. The arc-shaped clamping pieces are inserted into the inner flanges in a clamped mode, so that the upper box is rotationally installed, the upper box is positioned through elastic clamping of the clamping strips and the multiple columnar grooves, then angle adjustment of the upper box and an infrared remote control receiving module in the upper box is achieved, and limitation on the screen projector by the position of an external connecting wire is avoided.

Description

technical field [0001] The invention relates to the technical field of wired screen projectors, in particular to a wired screen projector and a screen projection method capable of realizing remote control and omnidirectional rotation. Background technique [0002] Currently, in fields such as conference systems and home entertainment systems, devices based on televisions or projections are usually used as screens. When these devices are used as screen projection devices for screen projection, because the devices based on TV or projection do not have touch function, so that they need to be operated on the device to be screened, and the wired screen projector is a kind of connection control A tool for connecting devices to large display devices, and the current mainstream method for wired projection is to use an HDMI cable to connect, but for mobile phone projection, an MHL cable is also needed to convert the signal into an HDMI signal; [0003] The prior art has the followin...

AI Technical Summary

Problems solved by technology

[0003] The prior art has the following deficiencies: the existing wired screen projector has a single structure, and because it needs to be connected with an external data line, in many cases, the position of the display device and the connected device limits the placement of the screen projector, resulting in Some screen projectors with infrared remote control function are difficult to effectively align the infrared receiving surface with the user, and because of their simple structure, remote screen projection cannot be realized. For example, when an emergency meeting is held, some personnel cannot rush back, and important information cannot Screen projection has certain limitations
