Abstract

The invention belongs to the technical field of focusing devices, and particularly relates to an automatic focusing device for a projector, and the device comprises a box body; and a focusing assembly which is connected with the box body and used for focusing a projector, wherein the focusing assembly comprises a vertical focusing assembly connected with the box body and a horizontal focusing assembly connected with the vertical focusing assembly. The vertical focusing assembly comprises a sliding plate member and a sliding frame piece connected with the sliding plate piece; the sliding frame piece is further provided with a gear transmission piece and a screw adjusting piece connected with the gear transmission piece; and the horizontal focusing assembly comprises a projector box. According to the invention, the device can perform focusing in the horizontal direction by arranging the horizontal focusing assembly, and in the embodiment, the device can perform focusing in multiple directions by combining the vertical focusing assembly and the horizontal focusing assembly, so that the focusing capability of the device is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of focusing devices, in particular to an automatic focusing device for a projector. 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 various devices through different interfaces to play corresponding video signals. The light sources used by the projector include traditional high High-intensity gas discharge light sources (such as ultra-high pressure mercury lamps, short-arc xenon lamps, metal halide lamps) and new light sources represented by LED light sources and laser light sources, projectors are widely used in homes, offices, schools and entertainment venues, depending on the working method , There are different types such as CRT, LCD, DLP, etc. Before using the projector, you need to adjust the focus of the projector. [0003] The existing auto-focusing devices for projectors generally can only focu...
