Problems solved by technology

[0003] In some commonly used fixed-focus projectors, the size of the projected image cannot be adjusted, so the only way to do this is to move the projector, let it move forward or backward, and control it according to the image projected on the screen. Relocation is more troublesome, and it needs to be at a certain angle when projecting on the screen, so it is difficult to control the irradiation angle of the projector

Abstract

The invention discloses a projector mobile base that can automatically adjust the size of the screen, relates to the field of projector equipment, and includes a chassis, a projector lifting mechanism, a projector, a reflection angle adjustment mechanism and a reflection angle driving mechanism. The projector lifting mechanism includes a hydraulic pressure The cylinder and the projector seat, the reflection angle adjustment mechanism includes a guide bar, a slide bar and a connecting rod, and the reflection angle drive mechanism includes a rack guide rail, a rack and a second motor. The present invention controls the height of the projector installed on the projector seat through a hydraulic cylinder, and is used to adjust the distance between the projection lens of the projector and the mirror in the mirror frame to achieve the size of the projected image reflected by the mirror. Engagement with the second motor makes the rack push up or pull down the slide bar, and lift up or pull down the lower end of the mirror frame to adjust the reflection angle of the mirror in the mirror frame.

Description

technical field [0001] The invention relates to the field of projector equipment, in particular to a movable base for a projector that automatically adjusts the size of a screen. Background technique [0002] Projectors are widely used in business office and teaching. They are connected with computers, VCD, DVD, BD, game consoles, DV, etc. through different interfaces to play corresponding video signals, and project images or videos onto the screen for display. [0003] In some commonly used fixed-focus projectors, the size of the projected image cannot be adjusted, so the only way to do this is to move the projector, let it move forward or backward, and control it according to the image projected on the screen. Relocation is more troublesome, and when projecting on the screen, it needs to be at a certain angle, so it is difficult to control the irradiation angle of the projector. Therefore, it is necessary to invent a projector mobile base that automatically adjusts the si...
