Description

Immersive projection support

Technical Field

The present invention relates to a projection rack, and more particularly to a rack structure capable of adjusting the projection height and distance and providing immersion in theoretical projection.

Background

People mainly use vision and hearing as main senses to receive affairs and information of an external environment, nowadays, in various fields such as art, audio and video, games, teaching or other fields, in order to make people completely put into absorption feeling and not be interfered by external factors related to other parts, people can be guided into an immersion state by an immersion theory (also called immersion experience), the immersion theory mainly makes people feel in the environment by the sense of presence, induces the interest and curiosity of people, and makes people independently improve the special attention, the immersion theory adopts VR technology (virtual reality), most commonly, namely, projection presentation is carried out on a spherical screen S, so that users can feel like the feeling of being personally on the scene by watching a 360-degree panoramic picture projected on the spherical screen S.

However, since the images projected by the general projectors P are all rectangular or trapezoidal (not shown), when the projector is projected on the spherical screen S, a plurality of projectors P (as shown in fig. 1) must be used, and 4 to 12 or more projectors P are erected according to the scale of the spherical screen S to project and cover the spherical screen S, and an image stitching technology software must be used to stitch and fuse the projected images of the projectors P to eliminate the overlapped images and completely present a 360-degree panoramic projected image, and if the projector is transferred to another spherical screen S for projection, the projectors P must be erected again, and the image stitching technology software is used to retest and calculate again, and the projected images of the projectors P (not shown) must be stitched and fused (not shown) by complicated and expensive software and hardware.

Therefore, it is an urgent need to provide a structure or device for immersion theoretical projection without using image stitching software and reducing the number of projectors, which is the direction of the present inventor.

Therefore, in view of the above-mentioned deficiency, the author of this creation will collect the relevant data, and through many evaluations and considerations, and through many years of accumulated experience in this industry, through continuous trial and modification, design this new patent.

SUMMERY OF THE UTILITY MODEL

The main objective of the present invention is to provide an immersive projection support, wherein a reflection unit and a projection platform are respectively disposed on two legs, the reflection unit is at least a convex mirror, the projection platform is used for a projector to be mounted and fixed, and the projector projects light toward the reflection unit, and the curvature of the convex mirror of the reflection unit is utilized to reflect the projection image of the projector onto a spherical screen, so as to display a panoramic projection image, thereby achieving a projection support structure for providing immersive experience.

To achieve the above object, the present invention provides an immersion type projection rack, which at least comprises: two foot stands, each having a lifting unit for adjusting the height of the foot stand, a distance adjusting unit for adjusting the distance between the foot stands; a reflection unit, which is disposed on the lifting unit of a stand and is at least a convex mirror; and a projection cloud platform, the projection cloud platform is arranged on the lifting unit of the other foot rest, the projection cloud platform can be used for installing and fixing a projector, and the projector can irradiate and project towards the reflection unit.

According to the aforesaid main features, the projection platform further comprises at least one rotation unit disposed at the bottom of the projection platform and pivotally connected to the lifting unit of the stand.

According to the above main features, the lifting unit and the distance adjusting unit are telescopic rod structures.

Detailed Description

To achieve the foregoing and other objects and advantages, the present invention provides a method and structure for implementing the same, which is capable of providing the following detailed description of the preferred embodiments of the invention.

Please refer to fig. 2 to 5, fig. 2 is a schematic diagram illustrating a structure of an immersion type projection rack according to the present invention; FIG. 3 is a schematic diagram illustrating an adjustment mode of an immersion type projection rack according to the present invention; FIG. 4 is a first schematic view of an immersion type projection rack according to the present invention; FIG. 5 is a second schematic view of an embodiment of an immersion type projection rack of the present invention.

As shown in the figures, the present invention provides an immersive projection stand, the projection stand comprising: two foot stands 10, a reflection unit 20 and a projection platform 30, wherein the reflection unit 20 is disposed on one foot stand 10, the reflection unit 20 is at least a convex mirror 21, and the projection platform

30 is disposed on another stand 10, the projection cradle head 30 is used for a projector P to be fixed by locking or clipping, and the projector P is projected toward the reflection unit 20 (as shown in fig. 2 and 3), and the image projected by the projector P is reflected onto a spherical screen S (as shown in fig. 4 and 5) by the curvature of the convex mirror 21 of the reflection unit 20, so as to display a panoramic projected image, thereby achieving a projection cradle structure providing an immersion experience.

More specifically, the foot stands 10 are respectively provided with a lifting unit 11, the lifting unit 11 can be used to adjust the height of the foot stand 10, the reflection unit 20 is disposed on the lifting unit 11 of one foot stand 10, the projection platform 30 is disposed on the lifting unit 11 of another foot stand 10, the lifting unit 11 can be used to adjust the height of the reflection unit 20 and the height of the projection platform 30, respectively, and a distance adjustment unit 12 is disposed between the foot stands 10, the distance adjustment unit 12 is used to adjust the distance between the foot stands 10, and the relative distance between the reflection unit 20 and the projection platform 30 (as shown in fig. 2 and 3) can be adjusted by a user according to the requirement of the field, so as to provide the best projection focal length and the best projection effect, and preferably, the lifting unit 11 and/or the distance adjustment unit 12 can adopt the same telescopic rod structure (as shown in fig. 2 and 3), but adopt other structures capable of achieving the same effect.
