Abstract

The embodiment of the invention discloses a projection host, and belongs to the technical field of projection. The projection host comprises a light source system used for emitting a light beam; an optical-mechanical system, located on the light emitting side of the light source system, and the optical-mechanical system being used for receiving the light beam and emitting a modulated light beam after modulation; and a lens, comprising a first moving assembly and a lens barrel. The first moving assembly comprises a first moving bearing shell and a first control assembly, the first moving bearing shell is slidably connected to the light emitting side of the optical-mechanical system, and the first control assembly is fixed to the light emitting side of the optical-mechanical system and is in transmission connection with the first moving bearing shell; the lens barrel is connected with the first movable bearing shell, and the first movable bearing shell is provided with a first light hole. According to the embodiment of the invention, the first control assembly drives the lens barrel to move, so that the movement precision of the lens barrel is ensured, the position accuracy of the lens projection area after movement is ensured, and the projection effect of the projection host is improved.

Description

[0001] The embodiment of this application claims the priority of the Chinese patent application with the application number 202010206877.1 and the title of the invention "Projection Host" and the application number 202010207094.5 and the title of the invention "Projection Host" submitted on March 23, 2020, all of which The content is incorporated by reference in the embodiments of this application. technical field [0002] The embodiments of the present application relate to the technical field of projection, and in particular to a projection host.
