Its structure mainly consists of four parts: an image processing system, a light source system, a projection system, and a control system. It uses special sketches or models as a basis, and then transforms these models into three-dimensional visual effects through advanced algorithms and optical systems. Users can directly observe these stereoscopic images without any additional equipment.

[0003] Patent application number 202011202744.3 discloses an image disk capable of holographic projection, comprising an image disk body with N sets of projection source images on the image disk body, each set of projection source images consisting of several individual images arranged in a cross-shaped symmetrical distribution. This invention also discloses a high-performance, cost-effective holographic projection display device, comprising an image disk, an imaging lens group, a driving device, and several light sources, each light source corresponding one-to-one with a number of imaging lenses.

[0020] As a preferred embodiment of the stereoscopic visual imaging projection display device of the present invention, a controller is fixedly installed on the mounting mechanism.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] 1. This invention, through the combined use of a display mechanism and 3D projectors, facilitates the formation of stereoscopic images. Several 3D projectors are set on the top of the display mechanism. Several projected images pass through several first projection lenses at the same position and are refracted by second projection lenses to form a visible stereoscopic projection inside the display mechanism for display. The simultaneous operation of several 3D projectors can increase the brightness to four times the original, which is very advantageous for projection in bright environments and can form a larger stereoscopic projection, allowing more viewers to clearly see the projected content.

[0023] 2. By setting a focusing mechanism, this invention can automatically adjust the focal length of the 3D projector. The automatic adjustment can respond quickly and accurately and can always maintain the optimal state, improving the projection effect and efficiency. By adjusting the focal length in real time, it can ensure that a clear and perfect image can be obtained in any environment, reducing the problem of visual quality degradation caused by improper human operation.

[0024] 3. This invention, through the combined use of a rotating mechanism and an adjusting mechanism, enables the synchronous adjustment of the angles of several 3D projectors. When the turntable on the adjusting mechanism drives the arc-shaped protrusion plate to rotate, it can squeeze the arc-shaped block. When the arc-shaped block is squeezed, it will drive the moving part to move. When the moving part moves, it drives the connecting part to rotate. The connecting part drives the rotating plate to rotate, and finally drives the 3D projector installed at the bottom of the rotating plate to rotate, thereby adjusting the projection angle of the 3D projector and realizing clear projection of different images. The synchronous operation of several 3D projectors can make the generated images appear simultaneously and be correctly superimposed, which helps to improve the stereoscopic effect and ensures that the images generated from each 3D projector have a consistent field of view and clarity.

[0025] 4. By setting a braking mechanism, the present invention can brake the turntable of the adjustment mechanism, preventing the turntable from rotating due to external collisions, which would cause deviation in the projection angle of the 3D projector and improve the stability of the projected image.

[0041] Example 1

[0042] Please see Figures 1-6 and Figures 9-12 A stereoscopic visual imaging projection display device includes an installation mechanism 1, a display mechanism 2 for displaying projection is fixedly connected to the top of the installation mechanism 1, and a number of 3D projectors 3 for projecting images are set on the top of the display mechanism 2. When the number of 3D projectors 3 project images simultaneously, a stereoscopic visual image is formed inside the display mechanism 2.

[0043] Furthermore, by using the display mechanism 2 and the 3D projector 3 together, it is easy to form a stereoscopic image. Several 3D projectors 3 are set on the top of the display mechanism 2. Several projected images pass through several first projection lenses 202 at the same position and are refracted by second projection lenses 203 to form a visible stereoscopic projection inside the display mechanism 2 for display. The simultaneous operation of several 3D projectors 3 can increase the brightness to four times the original, which is very beneficial for projection in bright environments and can form a larger stereoscopic projection, allowing more viewers to see the projected content clearly.

[0044] Furthermore, the installation mechanism 1 includes an installation platform 101, a column 102 fixedly connected to the top of the installation platform 101, a support frame 103 fixedly connected to the top of the column 102, and an embedded part 104 fixedly connected to the bottom of the installation platform 101. The embedded part 104 can be fixed in the foundation to fix the installation mechanism 1.

[0045] Furthermore, the display mechanism 2 includes a mounting frame 201, which is fixedly connected to the top of the mounting platform 101. First projection lenses 202 are fixedly connected to the front and rear sides and the left and right sides of the mounting frame 201, and a second projection lens 203 is fixedly connected to the bottom of the mounting frame 201.

[0046] Specifically, the first projection lens 202 is triangular in shape and the number is matched with the 3D projector 3. Several first projection lenses 202 have the same shape, and the second projection lens 203 is equilateral in shape, to form a visible projection space.

[0047] Specifically, the first projection lens 202 and the second projection lens 203 can refract the projected image. The 3D projector 3 projects the image onto the first projection lens 202 and the second projection lens 203. Unlike ordinary projectors that project images onto a flat surface, the specially designed light source of the stereoscopic projection device can project light from multiple angles. When the light hits the surface of the first projection lens 202 and the second projection lens 203, reflection and refraction occur. Some of the light is reflected, and the other part enters the interior of the glass, where it is refracted and propagates again. Through the intersection and overlap of these light rays, a floating image with a three-dimensional effect can be formed in space.

[0048] Furthermore, it also includes a rotating mechanism 5, which is matched with the number of 3D projectors 3 and is fixedly connected to the top of the mounting mechanism 1. The rotating end of the rotating mechanism 5 is fixedly connected to the 3D projector 3.

[0049] Furthermore, the rotating mechanism 5 includes a plate 501, which is fixedly connected to the inner wall of the support frame 103. A rotating cavity 502 is provided on the plate 501. A rotating plate 508 is movably connected to the inner wall of the rotating cavity 502. The 3D projector 3 is fixedly connected to the bottom of the rotating plate 508. A connector 509 and a fixing member 503 are rotatably connected to the surface of the rotating plate 508. The bottom of the fixing member 503 is fixedly connected to the top of the plate 501. A moving member 510 is rotatably connected to one end of the connector 509. An arc-shaped block 511 is fixedly connected to one side of the moving member 510.

[0050] Furthermore, a first rotating seat 504 is fixedly connected to one side of the rotating plate 508. A telescopic rod 507 is rotatably connected to the inner wall of the first rotating seat 504. A telescopic tube 506 is movably sleeved on the surface of the telescopic rod 507. A second rotating seat 505 is rotatably connected to one end of the telescopic tube 506. The bottom of the second rotating seat 505 is fixedly connected to the top of the plate 501. A spring 512 is provided in the inner cavity of the telescopic tube 506.

[0051] Specifically, during the rotation of the rotating plate 508, the telescopic rod 507 compresses the spring 512 inside the telescopic tube 506. When the rotating plate 508 returns to its original position, the spring 512 extends and drives the telescopic rod 507 to return to its original position, continuing to support and limit one side of the rotating plate 508.

[0052] Furthermore, it also includes an adjustment mechanism 6, which is fixedly connected to the rotation mechanism 5 to adjust the rotation angle of its rotating end, thereby enabling several 3D projectors 3 to rotate synchronously.

[0053] Furthermore, the adjustment mechanism 6 includes a motor frame 601, which is fixedly connected to the top of the support frame 103. A servo motor 602 is fixedly connected to the top of the motor frame 601. A rotating rod 608 is fixedly connected to the output shaft of the servo motor 602. A rotating frame 605 is rotatably connected to the bottom of the rotating rod 608. The rotating frame 605 is fixedly connected to the opposite side of the plate 501. An angle sensor 603 is fixedly installed on the top surface of the rotating rod 608. A turntable 604 is fixedly sleeved on the bottom surface of the rotating rod 608. Several arc-shaped protrusions 607 corresponding to the rotating mechanism 5 are fixedly connected to the surface of the turntable 604. The servo motor 602 is controlled by the controller 8. When the servo motor 602 works, it drives the rotating rod 608 to rotate. The rotating rod 608 drives the turntable 604 on its surface to rotate, thereby synchronously driving the lead screw arc-shaped protrusions 607 to rotate.

[0054] Furthermore, limiting plates 606 are fixedly connected to the top and bottom of the arc-shaped protrusion plate 607. When the arc-shaped protrusion plate 607 rotates, it contacts the arc-shaped block 511, causing the arc-shaped block 511 to move. At the same time, the limiting plates 606 slide on the top and bottom of the arc-shaped block 511 to limit the arc-shaped block 511 and prevent it from shaking up and down. The outermost part of the arc-shaped protrusion plate 607 is provided with an arc-shaped protrusion. One end of the arc-shaped protrusion extends further than the other end. Therefore, when the protrusion with the larger extension distance contacts the arc-shaped block 511, it can drive the arc-shaped block 511 to move.

[0055] Furthermore, a controller 8 is fixedly installed on the mounting mechanism 1. Angle sensor 603 detects the rotation angle of the rotating rod 608. The controller 8 receives the detection signal from angle sensor 603 and controls the servo motor 602 to work according to the detection signal. This can control the rotation range of the arc-shaped protrusion plate 607, thereby controlling the rotation angle of the 3D projector 3.

[0056] Furthermore, through the coordinated use of the rotating mechanism 5 and the adjusting mechanism 6, the angles of several 3D projectors 3 can be adjusted synchronously. When the turntable 604 on the adjusting mechanism 6 drives the arc-shaped protrusion plate 607 to rotate, it can squeeze the arc-shaped block 511. When the arc-shaped block 511 is squeezed, it will drive the moving part 510 to move. When the moving part 510 moves, it will drive the connecting part 509 to rotate. The connecting part 509 will drive the rotating plate 508 to rotate, and finally drive the 3D projector 3 installed at the bottom of the rotating plate 508 to rotate, thereby adjusting the projection angle of the 3D projector 3 and realizing clear projection of different images. The synchronous operation of several 3D projectors 3 can make the generated images appear simultaneously and be correctly superimposed, which helps to improve the stereoscopic effect and ensures that the images generated from each 3D projector 3 have a consistent field of view and clarity.

[0057] Example 2

[0058] As a second embodiment of the present invention, this embodiment is based on embodiment 1. Please refer to embodiment 1. Figures 7-8 A stereoscopic visual imaging projection display device further includes a focusing mechanism 4, which is fixedly connected to the projection end of the 3D projector 3 to adjust the focal length of the 3D projector 3.

[0059] Furthermore, by setting the focusing mechanism 4, the focal length of the 3D projector 3 can be automatically adjusted. The automatic adjustment can respond quickly and accurately, and can always maintain the optimal state, improving the projection effect and efficiency. By adjusting the focal length in real time, it can ensure that a clear and perfect image can be obtained in any environment, reducing the problem of reduced visual quality caused by improper human operation.

[0060] Furthermore, the focusing mechanism 4 includes a tube body 401, with an external threaded ring 402 rotatably connected to the surface of the tube body 401. An internal threaded ring 403 is threadedly fitted onto the surface of the external threaded ring 402. A lens cover 405 is fixedly connected to one end of the internal threaded ring 403, and a lens 404 is fixedly connected to the inner wall of the lens cover 405. A micro motor 410 is fixedly connected to the surface of the tube body 401. A pinion 409 is fixedly fitted onto the output shaft of the micro motor 410. A gear ring 407 meshes with the surface of the pinion 409. The gear ring 407 is fixedly fitted onto the surface of the external threaded ring 402 to drive it. When it is necessary to adjust the position of the lens 404 to change the focal length, the output shaft of the micro motor 410 drives the pinion 409 to rotate. The pinion 409 drives the gear ring 407 to rotate, thereby driving the external threaded ring 402 to rotate on the surface of the tube body 401. When the external threaded ring 402 rotates, it drives the internal threaded ring 403 to move, thereby driving the lens cover 405 and the lens 404 to move and change the focal length.

[0061] Furthermore, the tube body 401 is fixedly connected to the projection end of the 3D projector 3.

[0062] Furthermore, a groove 412 is provided on the surface of the tube body 401, and a retaining ring 408 is provided at one end of the external threaded ring 402. The retaining ring 408 rotates in the inner cavity of the groove 412 to limit the external threaded ring 402. A sliding groove 411 is provided on the inner wall of the tube body 401. A limiting rod 406 is fixedly connected to one side of the lens cover 405. The surface of the limiting rod 406 is movably connected to the inner wall of the sliding groove 411. When the limiting rod 406 moves inside the sliding groove 411, it limits the lens cover 405 and the internal threaded ring 403 to prevent them from rotating.

[0063] Example 3

[0064] As a third embodiment of the present invention, this embodiment is based on embodiment 1. Please refer to embodiment 1. Figures 13-14 A stereoscopic visual imaging projection display device also includes a braking mechanism 7, which is fixedly connected to the adjustment mechanism 6 to brake it.

[0065] Furthermore, by setting a braking mechanism 7, the turntable 604 of the adjustment mechanism 6 can be braked to prevent the turntable 604 from rotating due to external collisions, which would cause a deviation in the projection angle of the 3D projector 3 and improve the stability of the projected image.

[0066] Furthermore, the braking mechanism 7 includes a brake seat 701, a support member 702 is fixedly connected to the surface of the brake seat 701, a hydraulic cylinder 704 is fixedly connected to the top and bottom of the brake seat 701, a sliding plate 705 is fixedly connected to the piston rod of the hydraulic cylinder 704, a brake pad 706 is fixedly connected to the opposite side of the sliding plate 705, and a brake disc 703 is provided on the opposite side of the brake pad 706.

[0067] Furthermore, the support member 702 is fixedly connected to the surface of the motor frame 601.

[0068] Furthermore, the brake disc 703 is fixedly sleeved on the rotating rod 608. When the rotating rod 608 is braked, the piston rod of the hydraulic cylinder 704 extends and drives the sliding plate 705 to slide on the inner wall of the brake seat 701. The sliding plate 705 drives the brake pad 706 to press against the brake disc 703, preventing the brake disc 703 and the rotating rod 608 from rotating and shaking.

[0069] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention.
