Description

Technical Field

[0001] This invention relates to the field of 3D display technology, and more specifically, to a naked-eye 3D transparent display device. Background Technology

[0002] In naked-eye 3D transparent display devices, the relative positions of optical components and display panels are usually fixed and cannot be dynamically adjusted according to the viewer's actual distance. When the viewing position changes, the parallax images received by the eyes are difficult to match, resulting in a significant decrease in the 3D stereoscopic effect, and even ghosting or visual fatigue. This severely limits the adaptability of the device in different usage scenarios (such as close-range interaction and long-distance display).

[0003] Furthermore, in transparent display mode, ambient light from the background will pass through the display area and overlap with the foreground image, causing a severe decrease in contrast and color interference. Existing technologies lack an effective light transmittance adjustment mechanism and cannot dynamically control the transmission ratio of background light according to the intensity of ambient light. This makes it difficult to clearly identify transparent display content under bright background or complex lighting conditions. Users often need to adjust the viewing angle or position to barely obtain a readable image, which affects the user experience.

[0004] On the other hand, the external frame of the device is usually assembled from a frame, a front end plate and a rear end plate. In the existing technology, the assembly, fixing and disassembly of the three are relatively cumbersome, and bolts are often used. The assembly and disassembly are cumbersome and cannot be done quickly, which makes maintenance inconvenient. More importantly, this type of fixing structure lacks a safety locking mechanism. Anyone can arbitrarily remove the fixing, which can easily lead to damage to the internal optical components due to misoperation or unauthorized disassembly, and even affect the overall stability of the equipment. Summary of the Invention

[0005] Technical problems to be solved In view of the problems existing in the prior art, the present invention provides a naked-eye 3D transparent display device to solve the technical problems mentioned in the background art, such as the inability to adjust the 3D effect with viewing distance, the inability to switch the light transmittance according to the environment, and the cumbersome frame disassembly and assembly and lack of a safety locking mechanism.

[0006] Technical solution To achieve the above objectives, the present invention provides the following technical solution: a naked-eye 3D transparent display device, comprising a frame, a display panel, a lenticular plate, a display board, a front end plate, a rear end plate, a quick-lock device, an adjustment device, and a switching device. The lenticular plate is disposed behind the display panel, and the display board is disposed behind the lenticular plate.

The mounting frame is disposed inside the frame and the display panel is mounted therein. The frame is movably disposed inside the frame and the grating plate is mounted therein. The rack is fixedly disposed on the upper side of the frame and is used to drive the frame to move. The row-shifting groove is opened in the mounting frame, and the rack is slidably disposed in the row-shifting groove. The forward and backward movement of the grating plate is realized by gear and rack transmission, resulting in a compact structure.

[0008] According to one or more embodiments of the present invention, a plurality of shift sleeves are detachably provided in the frame, a shift rod is installed between the frame and the mounting frame, the shift rod slides through the shift sleeve, and a crank is connected to one end of the transmission rod, the crank being rotatably disposed on the outside of the frame; the cooperation between the shift rod and the shift sleeve guides the movement of the frame, and the crank facilitates manual adjustment.

[0009] According to one or more embodiments of the present invention, the unlocking mechanism includes an insertion rod, an insertion slot, and a strong magnetic plate. The insertion slot is formed in the quick-release lever, and the insertion rod slides into the insertion slot through the quick-release sleeve. The strong magnetic plate is fixedly disposed on the outer wall of the insertion rod. The locking block is made of a magnetic material, and the locking block and the strong magnetic plate have the same magnetic poles. Utilizing the principle of like poles repulsion, when the insertion rod is inserted, the magnetic force pushes the locking block out of the slot to achieve unlocking. After being pulled out, it automatically resets and locks. The operation is simple and has an authorized locking function.

[0010] According to one or more embodiments of the present invention, the quick-lock device further includes an outer sleeve, a reset spring, a reset rod, and a reset sleeve. The outer sleeve is detachably disposed on the outside of the quick-lock sleeve via a thread. The reset sleeve is fixedly disposed on the outer wall of the quick-lock sleeve. The reset rod is fixedly connected to one side of the reset frame, and one end of the reset rod slides into the reset sleeve. The reset spring is movably sleeved on the outside of the reset sleeve, and both ends of the reset spring are respectively connected to the inner wall of the reset frame and the outer wall of the quick-lock sleeve. The reset spring provides the power for the automatic reset of the lock block, and the reset rod and the reset sleeve guide the movement of the reset frame to ensure locking reliability.

[0011] According to one or more embodiments of the present invention, the switching device includes a bottom roller, a top roller, a bearing seat, a light-transmitting mechanism, and a switching drive mechanism. The top roller and the bottom roller are rotatably mounted at both ends in corresponding bearing seats. The top roller is located above the rear side of the display panel, and the bottom roller is located below the rear side of the display panel. The switching drive mechanism is used to drive the bottom roller and the top roller to rotate. The light-transmitting mechanism is located on the rear side of the display panel. The switching of curtains with different light transmittance is achieved by the synchronous rotation of the upper and lower rollers, and the structure is simple and reliable.

[0012] According to one or more embodiments of the present invention, the light-transmitting mechanism includes a blackout curtain, a semi-transparent curtain, a fully transparent curtain, and a transparent panel. The transparent panel is detachably mounted on the rear end plate. The two ends of the semi-transparent curtain are respectively connected to the fully transparent curtain and the blackout curtain. The fully transparent curtain is rolled up on the outside of the top roller, and the blackout curtain is rolled up on the outside of the bottom roller. The three types of curtains are connected in sequence, and the three modes of fully transparent, semi-transparent, and blackout can be quickly switched by the rolling up and down of the rollers to adapt to different ambient light requirements.

[0013] According to one or more embodiments of the present invention, the switching drive mechanism includes a divider, a drive motor, a synchronous belt, and synchronous pulleys. The drive motor is installed at the bottom inner side of the frame, and the output end of the drive motor is connected to the input end of the divider.

The divider ensures accurate switching position, and the synchronous belt realizes synchronous rotation of the upper and lower rollers, ensuring coordinated fabric retraction and unfolding.

[0014] Beneficial effects Compared with the prior art, the present invention provides a naked-eye 3D transparent display device, which has the following beneficial effects: 1. This invention features an adjustment device including a transmission rod, gear, rack, and crank. Users simply need to turn the crank to drive the gear and rack to move, allowing the frame with the grating plate to slide along the shifting rod, precisely adjusting the distance between the grating plate and the display panel. Combined with the self-locking characteristic of the damping shaft, the adjusted position is stably maintained. This structure allows users to dynamically adjust the optimal 3D effect position according to the actual viewing distance, effectively avoiding ghosting and visual fatigue, and improving the adaptability of the device in different scenarios.

[0015] 2. This invention features a switching device, including a top roller, a bottom roller, a drive motor, a divider, a synchronous belt, and three types of curtains: a fully transparent curtain, a semi-transparent curtain, and a blackout curtain. The drive motor drives the bottom roller to rotate via the divider, and the synchronous belt drives the top roller to rotate synchronously, enabling rapid switching between the three types of curtains: a fully transparent curtain for background display, a semi-transparent curtain for anti-glare, and a blackout curtain for high-contrast 2D display. Users can switch between the appropriate modes with one click according to the ambient light intensity, ensuring that the displayed content is clearly distinguishable under different lighting conditions, thus improving the user experience.

[0016] 3. This invention features a quick-lock device, including a quick-lock sleeve, a quick-lock rod, a locking block, a return spring, and a magnetic unlocking mechanism. During normal installation, the locking block automatically engages with the slot under the action of the return spring, achieving rapid locking. When disassembly is required, a special insertion rod (with a built-in strong magnetic plate) must be inserted to push the locking block out of the slot using the principle of like poles repulsion, allowing the quick-lock sleeve to be removed. This structure enables rapid disassembly and assembly while the magnetic unlocking mechanism restricts unauthorized disassembly, effectively protecting internal optical components and balancing maintenance convenience with equipment safety.

[0020] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0022] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings.

[0023] The core of this invention is to provide a naked-eye 3D transparent display device, which has a quick-release and unlocking mechanism, adjustable 3D effect and switchable light transmittance structure formed by the cooperation of components such as a quick-release device, adjustment device and switching device, and does not have the problems of inconvenient disassembly and assembly, non-adjustable 3D effect and single light transmittance mode.

[0024] Please see Figures 1-7In a first specific embodiment, the present invention provides a naked-eye 3D transparent display device, comprising a frame 1, a display panel 2, a lenticular plate 3, a display board 4, a front end plate 5, a rear end plate 6, a quick-lock device, an adjustment device, and a switching device. The lenticular plate 3 is disposed behind the display panel 2, and the display board 4 is disposed behind the lenticular plate 3. The front end plate 5 and the rear end plate 6 are respectively disposed on the front and rear sides of the frame 1. The quick-lock device is disposed on both sides of the frame and includes a quick-lock sleeve 61, a quick-lock rod 62, a locking block 63, a reset frame 64, a locking slot 65, a receiving slot 66, and an unlocking mechanism. Multiple quick-lock rods 62 are connected to both sides of the frame 1, and the receiving slot 66 is formed. Inside the quick-release sleeve 61, a slot 65 is formed outside the quick-release rod 62. A block 63 is movably disposed in the receiving slot 66. One end of the reset frame 64 passes through the side wall of the quick-release sleeve 61 and is fixedly connected to the block 63. The unlocking mechanism is used to unlock and remove the quick-release sleeve 61. The adjustment device is set on the upper side of the grating plate 3 and located inside the frame 1. The adjustment device includes a transmission rod 9, a rack 10, a mounting bracket 11, and a gear 12. The transmission rod 9 is rotatably mounted on the top of the mounting bracket 11 through a damping shaft. Two gears 12 are detachably mounted on the outside of the transmission rod 9. The gears 12 mesh with the corresponding racks 10. The switching device is set on the rear side of the display panel 4 and located inside the frame 1.

[0025] In the operation of existing technologies, fixed optical component positions are generally used, which results in the 3D effect not being able to adjust with the viewing distance; a back panel with fixed light transmittance is used, which results in the inability to switch the light transmission mode according to the ambient light; and the frame is fixed with bolts, which results in cumbersome disassembly and assembly and a lack of safety locking.

[0026] This application solves the practical problems of the above-mentioned unadjustable 3D effect, inability to switch light transmittance, inconvenient disassembly and assembly, and lack of authorized locking by adding a gear and rack adjustment device, a roller shutter switching device, and a magnetic unlocking quick card device.

[0027] Figures 1-5 This is a description of the regulating device.

[0028] As a further embodiment, referring to the above figures, the adjustment device also includes a frame 7, a mounting frame 8 and a row shifting groove 24. The mounting frame 8 is disposed inside the frame 1 and the display panel 4 is mounted therein. The frame 7 is movably disposed inside the frame 1 and the grating plate 3 is mounted therein. The rack 10 is fixedly disposed on the upper side of the frame 7. The row shifting groove 24 is opened in the mounting bracket 11 and the rack 10 is slidably disposed in the row shifting groove 24. The frame 7 is provided with multiple shift sleeves 25, and a shift rod 26 is provided between the frame 1 and the mounting frame 8. The shift rod 26 slides through the shift sleeve 25. One end of the transmission rod 9 is connected to a rocker handle 27, which is rotatably located on the outside of the frame 1.

[0029] In the prior art, the position of the grating plate is fixed. In this application, the crank 27 is turned to drive the transmission rod 9 and the gear 12 to rotate, and the rack 10 drives the frame 7 to move along the shift rod 26, so as to realize stepless adjustment of the distance between the grating plate 3 and the display panel 2 to adapt to different viewing distances.

[0030] Please see Figure 6 and Figure 7 As a further embodiment of the fast card device: the fast card device also includes an outer sleeve 67, a reset spring 68, a reset rod 69 and a reset sleeve 70. The outer sleeve 67 is detachably disposed on the outside of the fast card sleeve 61 by means of threads. The reset sleeve 70 is fixedly disposed on the outer wall of the fast card sleeve 61. The reset rod 69 is fixedly connected to one side of the reset frame 64, and one end of the reset rod 69 slides into the reset sleeve 70. The reset spring 68 is movably sleeved on the outside of the reset sleeve 70, and both ends of the reset spring 68 are respectively connected to the inner wall of the reset frame 64 and the outer wall of the fast card sleeve 61. The unlocking mechanism includes an insertion rod 81, an insertion slot 82, and a strong magnetic plate 83. The insertion slot 82 is opened in the quick-release lever 62. The insertion rod 81 slides through the quick-release sleeve 61 into the insertion slot 82. The strong magnetic plate 83 is fixedly installed on the outer wall of the insertion rod 81. The locking block 63 is made of magnetic material, and the locking block 63 and the strong magnetic plate 83 have the same magnetic poles.

[0031] Specifically, during normal installation, the locking block 63 is engaged in the slot 65 by the return spring 68, achieving a locking mechanism. For disassembly, a special insertion rod 81 must be inserted. The strong magnetic plate 83 and the locking block 63 repel each other, pushing the locking block 63 out of the slot 65, allowing the quick-release sleeve 61 to be removed. This structure enables quick assembly and disassembly, and unlocking is only possible using the special insertion rod, preventing unauthorized disassembly.

[0032] Please refer to Figure 4 and Figure 5 As a further embodiment of the switching device: the switching device includes a bottom roller 13, a top roller 14, a bearing seat 15, a light-transmitting mechanism and a switching drive mechanism. The top roller 14 and the bottom roller 13 are respectively rotatably installed in the corresponding bearing seats 15. The top roller 14 is located above the rear side of the display panel 4, and the bottom roller 13 is located below the rear side of the display panel 4. The switching drive mechanism is used to drive the bottom roller 13 and the top roller 14 to rotate. The light-transmitting mechanism is located on the rear side of the display panel 4. The light-transmitting mechanism includes a light-blocking curtain 28, a semi-transparent curtain 29, a fully transparent curtain 30, and a transparent plate 41. The transparent plate 41 is detachably installed on the rear end plate 6. The two ends of the semi-transparent curtain 29 are connected to the fully transparent curtain 30 and the light-blocking curtain 28, respectively. The fully transparent curtain 30 is rolled up on the outside of the top roller 14, and the light-blocking curtain 28 is rolled up on the outside of the bottom roller 13. The switching drive mechanism includes a divider 31, a drive motor 32, a timing belt 33, and timing pulleys 34. The drive motor 32 is installed at the bottom inner side of the frame 1. The output end of the drive motor 32 is connected to the input end of the divider 31. The output end of the divider 31 is connected to one end of the bottom roller 13. The two timing pulleys 34 are detachably installed at the other end of the top roller 14 and the bottom roller 13, respectively. The timing belt 33 is sleeved on the outside of the timing pulleys 34.

[0033] Specifically, the drive motor 32 drives the bottom roller 13 to rotate via the divider 31, which in turn drives the top roller 14 to rotate synchronously via the synchronous belt 33, thus enabling the switching of three types of curtains: the fully transparent curtain 30 displays the background when it is located behind the display panel 4; the semi-transparent curtain 29 provides anti-glare when it is located behind the panel; and the blackout curtain 28 provides high-contrast 2D display when it is located behind the panel. The divider 31 ensures precise switching positions.

[0034] In summary, the overall equipment is in use: When it is necessary to disassemble or maintain the front panel 5 or the rear panel 6 of frame 1. First, use the special insertion rod 81 to pass through one side of the quick-release sleeve 61 and slide it into the insertion slot 82. When the insertion rod 81 is fully inserted, the position of the strong magnetic plate 83 corresponds to the locking block 63. Due to the same magnetic poles, a repulsive force is generated, pushing the locking block 63 to move outward and disengage from the slot 65, so that the locking block 63 is put into the receiving slot 66. At the same time, the locking block 63 drives the reset frame 64 to slide outward. The reset frame 64 drives the reset spring 68 to stretch, and the reset frame 64 drives the reset rod 69 to slide outward along the reset sleeve 70. Then, pull the quick-release sleeve 61 and the insertion rod 81 outward together to remove the quick-release sleeve 61. At this time, the locking block 63 is no longer under magnetic force. The reset spring 68 resets and pulls the reset frame 64 to slide inward. The locking block 63 slides out of the receiving slot 66 and resets. After removing the insertion rod 81, the other quick-release sleeves 61 can be removed by following the above steps. Then, the front plate 5 or the rear plate 6 can be removed. Then, the internal components of the frame 1 can be maintained and repaired.

[0035] When it is necessary to reinstall and secure the front-end board 5 or the back-end board 6. Place the front plate 5 or the rear plate 6 on one side of the frame 1, so that multiple quick-locking rods 62 fixedly connected to one side of the frame 1 pass through the reserved holes of the front plate 5 or the rear plate 6. Then, fit the quick-locking sleeve 61 from the outside to the outside of the quick-locking rod 62. The rounded corner structure at the top of the quick-locking rod 62 will cooperate with the rounded corner structure on one side of the locking block 63, so that the rounded corner at the end of the quick-locking rod 62 pushes the locking block 63 outward, so that the locking block 63 drives the reset frame 64 to slide outward again, and the reset frame 64 will drive the reset spring 68 on one side to stretch again. At the same time, the reset frame 64 will drive the reset rod 69 to stretch outward along the reset sleeve 70 again, so that the locking block 63 will be retracted into the receiving groove 66 again. When the quick-locking sleeve 61 is fully fitted, the locking block 63 is locked into the slot 65 under the action of the reset spring 68, completing the quick locking. Since a special insertion rod must be used to unlock, authorized security locking is achieved.

[0036] When it is necessary to adjust the distance between the raster plate 3 and the display panel 4 First, rotate the crank handle 27 forward. The crank handle 27 drives the transmission rod 9 to rotate forward. The transmission rod 9 drives the two gears 12 to rotate synchronously, causing the two meshing racks 10 to slide along the shifting groove 24 respectively. The racks 10 drive the frame 7 to slide, and the frame 7 drives the shifting sleeve 25 to move along the shifting rod 26, thereby causing the lenticular plate 3 to shift and change the distance between it and the display panel 4. When the position of the lenticular plate 3 is adjusted appropriately, stop rotating the crank handle 27. Since the transmission rod 9 is rotatably mounted on the top of the mounting bracket 11 through the damping bearing, the transmission rod 9 and the gears 12 will not easily rotate, thus ensuring the structural stability of the lenticular plate 3 after the position is adjusted. By rotating the crank handle 27, the user can use the gear and rack mechanism to drive the 3D lenticular plate 3 to move back and forth, and adjust it to the optimal 3D effect position according to the viewing distance.

[0037] When it is necessary to switch the light transmittance First, the drive motor 32 is driven in the forward direction. The drive motor 32 drives the bottom roller 13 to rotate through the divider 31 connected to the output end. The bottom roller 13 rotates in the corresponding bearing seat 15, which in turn drives the synchronous pulley 34, which is detachably installed at its other end, to rotate in the forward direction. The synchronous pulley 34 drives the synchronous pulley 34 at the other end of the top roller 14 to rotate synchronously in the forward direction through the synchronous belt 33 sleeved on the outside. This achieves synchronous forward rotation of the top roller 14 and the bottom roller 13. At this time, the top roller 14 performs a winding action, and the bottom roller 13 performs a releasing action, so that the semi-transparent curtain 29 is wound up to the outside of the top roller 14. Furthermore, the semi-transparent curtain 29 will roll around the outside of the fully transparent curtain 30, while the light-blocking curtain 28 released by the bottom roller 13 will be placed behind the display panel 4, thus completing the switching of light transmittance. The user can use the forward and reverse drive motor 32 to move the strips with different light transmittances to the back of the display panel 4, thereby selecting the fully transparent curtain 30 (display), semi-transparent curtain 29 (anti-glare), or light-blocking curtain 28 (high contrast 2D display) modes. This roller shutter-type switching device achieves rapid switching between the three modes through mechanical means and is suitable for various scenarios such as display, anti-glare, and high contrast display.
