Examples
Referring to fig. 1, the present embodiment provides an exhibition system 100 comprising an imaging screen 10, a mirror 60, a projection device 20, and a display case 30.
The reflecting surface P1 of the reflecting mirror 60 corresponds to the imaging curtain 10; the projection device 20 is located between the imaging curtain 10 and the reflecting mirror 60 and corresponds to the reflecting mirror 60, so that the projection of the projection device is reflected to the imaging curtain 10 through the reflecting mirror 60 for imaging; the showcase 30 has a drawing plate 31 which can be drawn in a direction approaching or separating from the imaging screen 10; the mirror 60 and the projection device 20 are respectively disposed on the drawing plate 31 so that the size of the projection projected on the imaging screen 10 is changed when the drawing plate 31 is drawn.
When the exhibition system 100 in this embodiment is used, information to be exhibited is projected onto the imaging screen 10 for imaging after being reflected by the projection of the projection device 20 such as a projector onto the mirror 60. With this arrangement, imaging can be achieved in a smaller space. And the distance of the projection device 20 and the mirror 60 from the imaging screen 10 can be adjusted by pulling the pulling plate 31 to obtain a proper imaging size, if necessary.
Fig. 2, 3 and 4 show one implementation of the mirror 60 in this example. Referring to fig. 2 to 4, the mirror 60 in the present embodiment includes a bracket 61 and a movable portion 62 movably connected to the bracket 61; the reflecting surface P1 is provided on the movable portion 62 so that the orientation of the reflecting surface P1 can be adjusted by adjusting the movable portion 62. Alternatively, the movable portion 62 is rotatably connected to the bracket 61, and the rotation axis L1 of the movable portion 62 relative to the bracket 61 is parallel to the drawing plate 31 and parallel to the imaging screen 10, so that the movable portion 62 and the reflecting surface P1 thereon can be rotated and adjusted in pitch, thereby adjusting the projection height.
In this embodiment, the bracket 61 may be configured to magnetically engage the drawer plate 31 to allow the position of the mirror 60 on the display case 30 to be adjustable. In this embodiment, the drawing plate 31 may be provided as an iron plate, and a magnetic base 63 is provided at the bottom of the bracket 61, thereby achieving magnetic attraction between the bracket 61 and the drawing plate 31. The position of the mirror 60 can be conveniently moved when needed to effect another manner of adjustment. In one embodiment, the stand 61 includes a base 63 and a telescopic rod 64 connected to the base 63, and a telescopic end of the telescopic rod 64 is connected to the movable portion 62, so that the height of the movable portion 62 is adjustable. By providing the telescopic rod 64, the height of the lens 66 on the bracket 61 can be conveniently adjusted.
In the present embodiment, the movable portion 62 includes a chassis 65 and a lens 66 having a reflecting surface P1; the lens 66 is connected to the front face of the shelf 65; the sides of the shelf 65 extend laterally outward beyond the sides of the lens 66 to form a flange 67. Optionally, the flange 67 is provided as a fold that is bent towards one side of the lens 66. Thus, the portion of the light emitted from the projection device 20 toward the mirror 60 is reflected by the mirror 66 to the image screen 10 for imaging, and the light directed to both sides of the mirror 66 is blocked by the ribs 67 and is not directed to a person viewing the image screen 10 behind the mirror 60, causing glare. The surface of the flange 67 corresponding to the projection device 20 in this embodiment is set to be a non-mirror surface to avoid that undesirable reflected light forms undesirable images on the imaging screen 10. In other embodiments, the flange 67 may also be provided as a straight or curved edge.
The mirror plate 66 of the mirror 60 in this embodiment may be raw glass, float glass, or the like. The thickness of the lens 66 may be 0.1-6.0mm, and may be, for example, 0.5mm, 0.7mm, 1.1mm, 1.25mm, 1.9mm, 2.0mm, 3.0mm, 4.0mm, 5.0mm, etc. The lens 66 may be coated to enhance its optical properties.
Alternatively, the stripe direction of the mirror 60 is parallel to the horizontal direction.
Referring to fig. 5, 6 and 7, the display case 30 in this embodiment includes a case 32, and a drawable drawer 31 is provided on the case 32. The pull plate 31 is slidably engaged with the top of the cabinet 32, so as to serve as a top cover of the cabinet 32. The sliding fit of the pull plate 31 may be achieved by using a common sliding rail 34 or other sliding fit structure, which is not described herein.
Display case 30 serves as a support structure for projection device 20 and mirror 60, which should be configured to have a relatively stable structure that avoids the ease with which it can be moved during use to affect imaging stability. Of course, this does not mean that display case 30 must be fixedly positioned. Instead, a roller (not shown) may be provided at the lower end thereof for movement to move the entire display case 30 as needed to bring the mirror 60 and projection device 20 thereon to a suitable distance relative to the imaging screen 10 to form a suitable image.
In this embodiment, the front edge of the pull plate 31 is connected with a downward folded portion 35, and a label 37 can be provided on the upper surface of the folded portion 35 as a label of a product, so that a user can know the product conveniently. Optionally, a light may be provided on the upper surface of the fold 35 to illuminate the label.
The rear part of the cabinet 32 in the present embodiment has a vertical passage T1; a gap F1 is provided between the drawing plate 31 and the rear plate 38 of the cabinet 32, and the gap F1 communicates with the vertical passage T1 to allow the wire harness 21 of the projection apparatus 20 placed on the drawing plate 31 to pass through the gap F1 and the vertical passage T1 into the inside of the showcase 30.
The projection device 20 in this embodiment may be an existing projector such as a laser projector or the like. The specific structure thereof is not described herein.
To facilitate adjusting the height of the projection device 20 to accommodate the mirror 60 and the imaging screen 10 for proper imaging, the projector may be provided with an adjustable base for adjustment.
The embodiment of the invention also provides an exhibition method, which is based on the exhibition system 100; the exhibition method comprises the following steps: the information to be exhibited is reflected by the projection of the projection device 20 to the reflecting mirror 60 and then projected to the imaging curtain 10 for imaging, and the distance between the projection device 20 and the reflecting mirror 30 and the imaging curtain 10 is adjusted by drawing the drawing plate 31 so as to obtain imaging with proper size.
The above description is only of the preferred embodiments of the present invention and is not intended to limit the present invention, but various modifications and variations can be made to the present invention by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
