Mechanical auxiliary device and method for projection display and interaction

Abstract

The invention discloses a mechanical auxiliary device and method for projection display and interaction, and relates to the technical field of projector mechanical auxiliary equipment.The mechanical auxiliary device comprises a supporting table and a projector, a connecting base is fixedly connected to the bottom of the projector, and a plurality of first springs arranged in an annular array are fixedly connected to the bottom of the connecting base; a plurality of rotating devices arranged in an annular array are fixed to the peripheral wall of the connecting base, each rotating device comprises two mounting blocks and a rotating shaft, the two ends of each rotating shaft are rotationally connected with the two mounting blocks correspondingly, the mounting blocks are fixed to the peripheral wall of the connecting base, and a connecting assembly is movably connected to each rotating shaft; the position of the projector can be freely adjusted, it can be effectively guaranteed that the projector is in a stable state, the stability of a projection picture is improved, the projection direction can be changed, light supplementing treatment can be carried out in time, and the film watching experience of a user is improved.

Description

technical field [0001] The invention relates to the technical field of projector mechanical auxiliary equipment, in particular to a mechanical auxiliary device and method for projection display and interaction. Background technique [0002] A projector, also known as a projector, is a device that can project images or videos onto a screen. It can be connected to a computer, VCD, DVD, BD, game console, DV, etc. through different interfaces to play the corresponding video signal. [0003] Projectors are widely used in homes, offices, schools and entertainment venues. According to different working methods, there are different types such as CRT, LCD, DLP, etc. The projector needs to use some auxiliary tools in the process of using, and use auxiliary devices to control Projection effects and display screens. [0004] However, the existing projection auxiliary devices still have certain defects in use. First, such devices have complex structures and troublesome adjustments. It i...

Problems solved by technology

[0004] However, the existing projection auxiliary devices still have certain defects in use. First, such devices have complex structures and troublesome adjustments. It is difficult to adjust the position of the projector relative to the projection cloth, resulting in poor picture effects and low flexibility. , the direction, position and angle of the projector cannot be freely adjusted according to actual needs. At the same time, due to the influence of the external environment, the projector will shake, which will cause the picture to shake and affect the viewing experience.
