Abstract

The invention relates to the technical field of projection, in particular to laser projection equipment. The equipment is used for improving the host adjusting efficiency of the projection equipment. The laser projection equipment comprises a projection equipment host and an adjusting device. The adjusting device comprises an upper platform, a lower platform, a supporting assembly and three first adjusting mechanisms. The lower platform and the upper platform are arranged in parallel. The supporting assembly is arranged between the upper platform and the lower platform, the supporting assembly is fixed to the lower platform, and the supporting assembly is spherically hinged to the upper platform. Each first adjusting mechanism comprises an adjusting rod and a first driving assembly, and the adjusting rods of the three first adjusting mechanisms are evenly distributed in the circumferential direction of the supporting assembly. One ends of the adjusting rods are spherically hinged to the upper platform, and the other ends of the adjusting rods are connected with the first driving assemblies.

Description

Technical field [0001] The present invention relates to the field of projection techniques, and more particularly to a laser projection device. Background technique [0002] Laser TV includes laser projection devices and projection screens. The laser projection device uses projection to project an image to the projection screen, thereby having a set relative position and relative angle between the laser projection device and the projection screen. [0003] After the laser TV is installed, if the user is unintentionally changed to the position of the laser projection device or the projection screen, the relative angle between the laser projection device and the projection screen changes, thereby causing a laser projection device to project a distortion on the projection screen. , Affect the user's viewing experience. At this time, the laser projection device or projection screen needs to be adjusted so that the relative angle between the laser projection device and the projection ...
