Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
The present embodiment provides a reflective projection display system, as shown in fig. 1, the reflective projection display system includes a base 104, a projector 101 and a projection screen 103 mounted at one end of the base 104, and a reflector 102 mounted at the other end of the base 104, wherein light projected by the projector 101 is reflected by the reflector 102 and reaches the projection screen 103, so that projected image information of the projector 101 is reflected to the projection screen 103 for display, and a viewer can stand behind the reflector 102 to view the projected image information.
The projection screen 103 is installed above the projector 101, the reflector 102 is installed at 1/2 of the projection distance required by the projector 101, and in order to avoid the original path of the projector projection light from being reflected, the reflector 102 is installed not perpendicular to the projection light but inclined at a certain angle; therefore, the projection distance can be reduced by reflecting the projected image information to the projection screen through the reflector 102, so that the installation volume can be reduced while the whole reflection system can be integrally installed, and the product volume is smaller.
The projector 101 may be a fixed-throw-ratio projector, or may be a variable-throw-ratio projector, the mirror 102 is a general mirror, the projection screen is preferably a transparent projection screen with a glass substrate, and a viewer can view not only an image on the mirror side but also projected image information on the back of the projection screen.
And the said reflector is installed in front of the projector lens at 1/2 of the projection distance needed by the non-reflection type projection system, and if the projector with variable projection ratio is selected, the installation position of the reflector is moved between 1/2 of the minimum calculated projection distance and 1/2 of the maximum projection distance, and the inclination angle of the reflector installation is fixed during the movement.
As shown in fig. 1 and 2, the projection screen 103 is mounted on the base 104 by a projection screen mount 107, and the projection screen 103 is detachably mounted on the projection screen mount 107; specifically, as shown in FIG. 2, projection screen mount 107 is removable, and projection screen mount 107 is inserted into screen mount slot 204 when installed, quickly positioned by pull tab self-locking pull pin 203, and tightened with screw 202.
Or, when the projection screen is a projection screen with a smaller size, the detachable projection screen base can be omitted, and the design of the damping rotating shaft is adopted, namely, the first damping rotating shaft for installing the projection screen is arranged on the projection screen base.
And, for the stability of projector's installation, the said projector 101 is equipped with a projector fixing fastener 105 used for fixing the projector 101 in a fixed position. In addition, in order to enhance the aesthetic property of the whole projector, the shell 201 is added, which can wrap the projector 101 and the projector fixing fastener 105 and also play a role in protecting the projector.
As shown in fig. 1 and 4, the reflector 102 is mounted on the base 104 through a reflector base 106, and a second damping rotating shaft similar to a notebook computer is mounted at the bottom of the reflector base 106, so that the reflector 102 can be rotated and folded towards the projector side, and when not in use, especially during packaging and transportation, the volume can be reduced, and the chance of breakage can also be reduced.
As shown in fig. 1 and 3, a slot 301 is formed at the bottom of the mirror base 106, the slot 301 is used for adjusting the position of the mirror, the adjustment range is 1/2 of the difference between the projection distances calculated according to the maximum value and the minimum value of the projector throw ratio, and the position adjustment direction is the projection light direction. If a projector with a fixed projection ratio is adopted, a position adjusting groove can be omitted, and the reflector can be installed at a fixed position.
The above description is only exemplary of the present invention and should not be construed as limiting the present invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
