Abstract

This invention discloses a projection system including a body of the projector and a supporting base. The body has a projection lens for projecting images and supported by the supporting base. As the relative position of the body and the supporting base changed, the elevation angle of the projected images also changed. The upper moving mechanisms are formed on the body, and the lower moving mechanisms which correspond to the upper moving mechanisms are formed on the supporting base. The projection system also comprises a fixation unit, and a locating portion engaged to the fixation unit on the supporting base. When the body moves on the supporting base to the angle met the need of the user, the fixation unit engages with the locating portion and fixes the projector on the supporting base.

Description

Projection system

The present invention is a projection system; in particular, a projection system that changes the projection elevation angle according to the relative position of the fuselage and the support base.

In recent years, the characteristics of the projector that can be carried and moved easily become more and more important. When the same projection frame is set at different locations, it is often necessary to adjust the projection angle due to environmental factors such as the height of the display and the projection distance. At present, projectors on the market generally have one or more spiral support legs under the fuselage. When adjusting, the projector needs to be lifted first, the support stand is rotated to extend or shorten, and the projector is lowered. After that, it can be confirmed whether the adjusted projection angle meets the requirements. The length of the support tripod is extended or shortened. The above process is often repeated multiple times because the projection result cannot be directly observed during the adjustment. This structure is inconvenient to use and It takes more adjustment time to get the proper projection angle.

In order to solve the above problems, the present invention proposes a projection system including a projector body (hereinafter referred to as a body) and a support base having a lens for projecting an image and supporting the support seat as a body and a support base. When the relative position of the front and rear changes, the elevation angle of the projected image of the lens also changes. In the fuselage has an upper movable mechanism, and in the support base, there is an upper movable machine The lower movable mechanism of the cooperation cooperates to cause relative displacement of the fuselage relative to the support base by relative movement between the upper movable mechanism and the lower movable mechanism. The projection system includes a fixing member and a positioning portion that is fixed to the fixing member on the support base. When the body and the support base are moved to a position corresponding to a user's desired position, the fixing member and the positioning portion can be fixed. The projector is fixed to the support base.

Therefore, when the projection system of the present invention is used to adjust the elevation angle of the fuselage, it is possible to simultaneously observe whether the adjustment result meets the requirements, and eliminate the process and time of repeated adjustment. In addition, by using the actuating and fixing manner of the fixing member and the positioning portion, the angle of the projection can be quickly adjusted and the position of the projector can be fixed, which is more time-saving than the conventional spiral support stand needs to rotate the support leg slowly. At the same time, the user can record the scale of the required adjustment by using the marking symbol on the slide. When the projector is to be re-arranged in the same environment for the next time, the result of the previous adjustment can be directly applied.
