Description

Technical Field

[0001] The utility model relates to the technical field of three-dimensional display, in particular to a three-dimensional display device. Background Art

[0002] With the popularization and application of digital technology, existing science and technology have entered a new world of three-dimensionality. As the most modern imaging technology today, holographic stereoscopic imaging technology has been widely used in the field of object display. Through three-dimensional holographic projection, users can have a more intuitive and in-depth understanding of the displayed objects. Some three-dimensional display devices include a base with a square cross-section and a fixing frame and a turntable structure arranged on the base. The fixing frame is fixedly installed on the upper surface of the base. The fixing frame is a vertical plate-like structure, and there are two of them. The two fixing frames are distributed on both sides of the square base opposite to each other. The fixing frame is fixedly connected to the guide of the rodless cylinder by bolts. A rodless cylinder is vertically installed on both sides of the upper and lower ends of the rail and each fixed frame. The new model is easy to use, and the universal wheel facilitates movement in the plane space. The rodless cylinder enables the new model to adjust the position up and down, and the turntable structure enables the new model to adjust the display angle. However, after the three-dimensional display device is exhibited in one place, it needs to be moved to another city and displayed again in another city. This requires frequent transportation of the device itself. The device is not equipped with a transportation protection unit. During the transportation process, it is very likely to collide with other items transported together, which may cause damage to the three-dimensional display part. For this reason, we propose a three-dimensional display device. Utility Model Content

[0021] Storage buffer protection mechanism 5: It includes a stud 51, a lifting seat 52, an L-shaped plate 53, a damper 54 and a spring 55. The stud 51 is rotatably connected to the bottom wall of the shell 1 through a bearing. The upper end of the stud 51 is threadedly connected to the lifting seat 52. The upper side of the lifting seat 52 and the lower side of the display stand 3 are both provided with evenly distributed L-shaped plates 53. Dampers 54 and springs 55 are provided between two vertically adjacent L-shaped plates 53. The springs 55 are movably connected to the outer ends of adjacent dampers 54. The storage buffer protection mechanism 5 also includes a fixed seat 56, a gear 57 and a motor 58. The fixed seat 56 is arranged on the bottom wall of the shell 1. A motor 58 is provided on the upper side of the fixed seat 56. The input end of the motor 58 is electrically connected to the output end of the single-chip computer 2. The output shaft of the motor 58 and the screw The lower ends of the columns 51 are each provided with a gear 57, which is meshed with each other. The storage buffer protection mechanism 5 also includes a guide rod 59, which is arranged on the bottom wall of the shell 1. The upper end of the guide rod 59 is slidably connected to the circular hole of the lifting seat 52. The upper side of the display stand 3 is provided with symmetrically distributed avoidance holes 7. The guide rod 59 and the stud 51 are both installed in conjunction with adjacent avoidance holes 7. The bottom wall of the shell 1 is provided with a laser sensor 6, which is bidirectionally electrically connected to the single-chip microcomputer 2. The upper right end of the shell 1 is provided with symmetrically distributed connecting seats 8, and the connecting seats 8 are rotatably connected with a flip cover 9 through a rotating shaft. The lower side of the shell 1 is provided with evenly distributed universal wheels 10. When transporting the three-dimensional display device, the single-chip microcomputer 2 first starts the motor 58 so that its output shaft drives the screw The column 51 rotates, and the stud 51 is connected by a thread, so that the lifting seat 52 moves along the guide rod 59 to the inner bottom end of the shell 11. The lifting seat 52 indirectly drives the display stand 3 into the shell 1 through the L-shaped plate 53, thereby storing and protecting the three-dimensional display part of the device, and preventing the three-dimensional projection display part of the three-dimensional display device from being damaged due to accidental contact during the later transportation. During this process, the single-chip microcomputer 2 starts the laser sensor 6, and the laser sensor 6 emits a light signal to the lower side of the lifting seat 52 and reflects it back to the initial position. The vertical movement distance of the lifting seat 52 is measured according to the propagation speed and time of the light signal, and the measurement result is transmitted to the single-chip microcomputer 2 in the form of an electrical signal, so that the single-chip microcomputer 2 controls the motor 58 according to the measurement result, which can automatically The three-dimensional display part of the device is accurately stored inside the shell 1, and the upper ends of the guide rods 59 and the studs 51 are passed through the adjacent avoidance holes 7. Then the flip cover 9 is reversed to rotate it around the rotation axis, thereby covering the top of the shell 1, and then completely wrapping and protecting the three-dimensional projection display part of the three-dimensional display device. Then the device is pushed to move its position through the universal wheels 10. During the transportation of the three-dimensional display device, the external interference force on the device itself is transmitted to the lifting seat 52 through the shell 1. Through the elastic contraction of the spring 55 and the friction or hydraulic resistance of the elastic elements and the bearing elements inside the damper 54, the interference force is converted into heat energy for release, thereby preventing the interference force from causing vibration damage to the electrical components in the three-dimensional display device.The device protects the three-dimensional display part by storing and wrapping it to avoid collision damage during transportation. At the same time, the device uses damping elasticity to reduce shock to avoid vibration damage during transportation. The three-dimensional display device has a good transportation protection effect.

[0022] The working principle of a three-dimensional display device provided by the present invention is as follows: when using the three-dimensional display device, the single-chip microcomputer 2 starts the 3D holographic projector, and the light emitted by the 3D holographic projector is diffracted and projected onto the upper middle part of the transparent glass 4 through the reflective surface of the transparent glass 4, thereby achieving a three-dimensional display effect. When the three-dimensional display device is transported, the single-chip microcomputer 2 first starts the motor 58 so that its output shaft drives the stud 51 to rotate. The stud 51 is connected through a thread so that the lifting seat 52 moves along the guide rod 59 to the inner bottom end of the shell 11. The lifting seat 52 indirectly drives the display platform 3 into the shell 1 through the L-shaped plate 53, thereby storing and protecting the three-dimensional display part of the device, and preventing the three-dimensional projection display part of the three-dimensional display device from being damaged due to accidental collision during later transportation. In this process, the single-chip microcomputer 2 starts the laser sensor 6, and the laser sensor 6 emits a light signal to illuminate the lower side of the lifting seat 52 and reflect it back to the initial position. The lifting seat 52 is adjusted according to the propagation speed and time of the light signal. The vertical movement distance of the lowering seat 52 is measured, and the measurement result is transmitted to the single-chip microcomputer 2 in the form of an electrical signal, so that the single-chip microcomputer 2 controls the motor 58 according to the measurement result, and can automatically and accurately store the three-dimensional display part of the device into the inside of the shell 1. The upper ends of the guide rods 59 and the studs 51 pass through the adjacent avoidance holes 7, and then the flip cover 9 is reversed to rotate it around the rotation axis, thereby covering the top of the shell 1, and then completely wrapping and protecting the three-dimensional projection display part of the three-dimensional display device, and then pushing the device to move its position through the universal wheel 10. During the transportation of the three-dimensional display device, the external interference force exerted on the device itself is transmitted to the lifting seat 52 through the shell 1, and the interference force is converted into heat energy through the elastic contraction of the spring 55 and the elastic elements and bearing elements inside the damper 54 through friction or hydraulic resistance, thereby avoiding the interference force from causing vibration damage to the electrical components in the three-dimensional display device, and the three-dimensional display device has a good transportation protection effect.
