Embodiment
The advantage of the present invention is set forth further below with reference to drawings and Examples.
First Fig. 1 to Fig. 4 is referred to, what illustrate is the base unit----casing type projection arrangement 100 forming many casings optical projection system in the present invention, its main body is a casing operating room 110, this casing operating room 110 by the vertical curtain bracing frame 121 and the vertical curtain 122 that are arranged on its front portion, and left side, right side and rear side three face wall bodies 111 form.Left and right, rear three side wall bodies are provided with ventilating opening 112, rear side body of wall is also provided with one 113.In casing operating room 110, be provided with an adjustment support 131 and be arranged on the vertical curtain projector 132 on this adjustment support 131.Vertical curtain projector 132 is to the projection imaging of vertical curtain 122.The position of vertical curtain 122 is controlled by the vertical curtain regulating device 123 stood on act bracing frame 121, and vertical curtain regulating device 123 can comprise the motor (not shown) controlling vertical curtain 122 vertical position (upper and lower) and horizontal level (left and right) further.The position of thirty years of age act of projector 132 controls by regulating support 131, regulate support 131 can comprise two the motor (not shown) regulating vertical curtain projector 132 vertical position (upper and lower) further, and regulate the manual regulating device (not shown) of vertical curtain projector 132 horizontal level (front, rear, left and right), such as screw mandrel.
For the ease of this casing type projection arrangement 100 mobile, in the bottom of casing operating room 110, several universal caster wheels can be installed.
Based on above-mentioned setting, can comprehensive adjustment screen, can comprehensive adjustment projector make image more clear.In addition, adopt the projection arrangement of integrated form body structure, optimize installation steps, reduce set-up time and installation requirement, realize the immediate shipment of virtual reality system, namely with and namely tear open, namely remove function.Box typed structure reduces the loss of projection ray equally, and the effective ambient light that reduces, to the interference of virtual reality light path system, can suppress the light pollution that may exist simultaneously.
In the preferred embodiment, owing to being arranged in casing operating room 110 by projector 132, casing operating room 110 has formed projector 132 and the barrier of external environment, serves the effect of dust protection to a certain extent.Certainly, putting dust effect to strengthen further, a top cover can be added at top, casing operating room 110.Like this, box typed structure farthest can reduce the impact of dust in air on service life of equipment, makes equipment keep clean for a long time and runs efficiently.
In order to improve the authenticity of virtual environment projection, a ground curtain 141 and ground curtain projector 142 can be added in some cases in this casing type projection arrangement 100.Ground curtain 141 is arranged on the bottom of vertical curtain 122, and extends forward from the front portion of casing operating room 110.Ground curtain projector 142 can be arranged on the upper end of front portion, casing operating room 110, such as, be arranged in the overarm of erection on vertical curtain bracing frame 121, for ground curtain 141 projection imaging.
The space that can increase this projection arrangement 100 and take is set due to ground curtain 141, nor is convenient to mobile.In order to address this problem, can arrange a ground curtain platform 150 in the bottom of casing operating room 110, the left and right sides of this ground curtain platform 150 is provided with slide rail 151, and ground curtain can move in this platform along slide rail, and is contained among this platform.
Consider in practice, the width of ground curtain 141 may be designed to the width exceeding casing operating room 110, ground curtain 141 can be designed to formed by least two pieces of panel splicings, and comprise one for control at least one piece of panel relative to other panels rise, fall or overlapping elevation and subsidence regulating device.In the preferred embodiment, ground curtain 141 is spelled paving by the square anti-electric wooden boards of three block lengths and is formed, three pieces of panels are by left, center, right arrangement, by operation elevation and subsidence regulating device, middle panel can rise, the panel of the right and left respectively can move a part to centre, makes centre panel overlapping with the faceplate part of the right and left, thus shortens the width of ground curtain 141.After lifting, overlap, ground curtain 141 can successfully be contained among ground curtain platform 150 along slide rail 151.
Design like this, this casing type projection arrangement 100 can stretch out ground curtain according to actual user demand or is contained in by ground curtain among the ground curtain platform of casing chamber bottom.
As shown in Figure 5 to Figure 6, for two casing optical projection systems 200 that one embodiment of the present invention provides, this system is by side by side and establish two casing type projection arrangements 100 form, one whirligig 210 is installed between projection arrangement, this whirligig 210 can be by motor-driven rotating shaft, also can be that other can allow two casings relatively rotate, or the device placed at an angle.As shown in Figure 5, two casings are shape side by side.As shown in Figure 6, two casings are 90 degree of angles, to form one or three surface imaging virtual environments.In order to two casings can be allowed to form the state shown in Fig. 6 smoothly, need first the ground curtain of a casing type projection arrangement to be recovered in ground curtain platform, then by whirligig 210, two casings are rotated into 90 degree of angles.
As shown in Fig. 7, Fig. 8 and Fig. 9, be three casing optical projection systems 300, in normal conditions, as shown in Figure 7, three casings 100 connect in being arranged side by side by whirligig 310, in order to realize virtual immersion effect, the ground curtain of two casings in left and right is retracted, then basis is by whirligig to middle housing 90-degree rotation, forms the virtual environment of four surface imagings, as Fig. 8.In addition, as shown in Figure 9, left box body formula projection arrangement is only had to have rotated 90 degree to middle casing type projection arrangement.
And in other some embodiments, the anglec of rotation between each casing can be fixed with the environment of reality projection, a controller such as can be adopted to control the content of vertical curtain projector and/or ground curtain projector imaging, and simultaneously according to the anglec of rotation between each casing of different content-controls.
According to above-mentioned setting, the preferred embodiment of the present invention provide two/tri-casing optical projection systems can need to change the position relationship of each casing according to different projection imagings.
Should be noted that, embodiments of the invention have preferably implementation, and not any type of restriction is done to the present invention, any person skilled in art of being familiar with may utilize the technology contents of above-mentioned announcement change or be modified to equivalent effective embodiment, in every case the content of technical solution of the present invention is not departed from, the any amendment done above embodiment according to technical spirit of the present invention or equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
