Description

Technical Field

[0001] This utility model relates to the field of imaging optical equipment, and in particular to an integrated device of a remote image screen and a reading / writing station. Background Technology

[0002] The main cause of myopia in students is often excessive close-range use of the eyes for extended periods. In modern society, children usually need to look at screens for long periods of time for learning and entertainment, while also engaging in activities such as writing and reading, which leads to eye fatigue and makes them prone to myopia.

[0003] To address this issue, existing technologies employ far-viewing screens, which magnify and display the content of electronic screens at a greater distance, thereby transforming near-field vision into far-field vision and thus preventing myopia.

[0004] However, most far-viewing screen products on the market currently require a document scanner to achieve the distance effect when using non-electronic reading materials such as books. However, document scanners have latency issues, resulting in a poor writing experience for students. Using both a reading desk and a far-viewing screen takes up a lot of desktop space, which is extremely inconvenient. Utility Model Content

[0005] The purpose of this utility model is to address the deficiencies in the above-mentioned technology by providing an integrated device that combines a remote image display and a reading / writing station, enabling switching between the functions of the remote image display and the reading / writing station without the need for a document scanner or other similar devices, thus facilitating use.

[0009] In the above solution, a screen compartment is set below the observation compartment. Optical components inside the observation compartment project and magnify the displayed electronic reading material. A display screen assembly is set at the bottom of the screen compartment. When the electronic reading material is fixed by the display screen assembly, the device can be used as a telephoto screen; when used as a reading / writing station, the display screen assembly is folded close to the screen compartment shell to provide space for non-electronic reading materials. This achieves an integrated setup of the telephoto screen and the reading / writing station, making it convenient to use.

[0011] A beam splitter is provided between the concave mirror and the observation window. The beam splitter is tilted, with its lower edge close to the observation window and its upper edge far from the observation window.

[0012] The observation window is equipped with a defocusing lens.

[0013] In some possible implementations, an adjustment assembly is provided on the side of the first housing of the observation chamber opposite to the observation window;

[0014] The adjustment assembly includes a support rod fixedly connected to the screen compartment and a sleeve fixedly connected to the first housing of the observation compartment; the support rod and the sleeve are slidably connected and can be locked.

[0015] In some possible implementations, the screen compartment includes a back panel connected to the support rod;

[0031] This application provides an integrated device combining a remote image display and a reading / writing station. By changing the shape of the screen compartment, it enables quick switching between the functions of a remote image display and a reading / writing station without the need for other equipment, making it convenient for users.

[0032] To facilitate a further understanding of the technical solution of this application, the application scenarios of the integrated far-viewing screen and reading / writing station are described below: The integrated far-viewing screen and reading / writing station in this application is mainly used by teenagers for reading and writing. By setting optical components within the observation chamber to magnify and extend the content of the reading material on the screen chamber, it transforms near-distance vision into far-distance vision, avoiding excessive near-distance eye strain during learning and entertainment, and effectively preventing the occurrence and development of myopia in children and adolescents. Specifically, the display screen component within the screen chamber is folded. When the display screen component is lowered, it is in far-viewing screen mode, allowing the reading material to be fixed in place; when the display screen component is folded, it provides space for non-electronic reading materials, such as books or notebooks, and in this mode, it is in reading / writing station mode, allowing the user to read and write.

[0033] The following description, in conjunction with the accompanying drawings, further illustrates this implementation case:

[0034] Depend on Figure 1 — Figure 8 As can be seen, this application includes an observation chamber 1 and a screen chamber 2 located below the observation chamber 1. It should be noted that the integrated far-viewing screen and reading / writing station device in this application can be equipped with a stand, which is fixedly connected to the desktop via the stand 6. As an example, see... Figure 5 , Figure 6This application includes a housing 3, which is fixedly connected to the observation chamber 1. The housing 3 is used to connect the bracket 6, which connects the device of this application to the desktop.

[0035] To facilitate switching between the far-viewing screen and the reading / writing station functions, the observation chamber 1 and the screen chamber 2 are connected by an adjustment component in this application. The adjustment component is mainly used to adjust the distance between the observation chamber 1 and the screen chamber 2, thereby adjusting the distance between the reading material in the screen chamber 2 and the optical components in the observation chamber 1. The adjustment component can be manually adjusted, such as by using a lead screw nut, sliding rod, or other adjustment mechanism; or it can be automatically adjusted, such as by using an electric push rod to adjust the distance between the two components by extending or retracting the electric push rod. Additionally, this application provides an observation window 11 on the side of the observation chamber 1 corresponding to the optical components, through which the user can read or write.

[0036] This application places the display assembly 4 at the bottom of the screen compartment 2 to maximize the viewing distance and reduce the overall height of the device. Specifically, when used as a far-viewing screen, refer to... Figure 2 The display assembly 4 is used to hold the electronic reading material. At this time, the display assembly 4 is positioned parallel to the desktop, and the electronic reading material is placed on the display assembly 4. To enable switching between the functions of a display screen and a reading / writing station, the display assembly 4 is foldable relative to the screen compartment 2. When used as a reading / writing station, refer to... Figure 3 , Figure 4 The display assembly 4 is folded relative to the screen compartment 2. The folded display assembly 4 is perpendicular to the desktop and placed on the side of the screen compartment 2 away from the user. At this time, the bottom of the viewing compartment is the desktop, and books, notebooks and other non-electronic reading materials can be placed on the desktop. At this time, the device is used as a reading and writing table.

[0037] In the above solution, a screen compartment 2 is set below the observation compartment 1. Optical components installed in the observation compartment 1 project and magnify the reading material inside the screen compartment 2. A display screen assembly 4 is set at the bottom of the screen compartment 2. When the electronic reading material is fixed by the display screen assembly 4, the device can be used as a far-viewing screen; when used as a reading / writing station, the display screen assembly 4 is folded close to the screen compartment shell to provide space for non-electronic reading materials. This achieves an integrated design of the far-viewing screen and the reading / writing station, making it convenient to use.

[0038] In some alternative implementations, see [link to implementation details]. Figure 6The observation chamber 1 includes a first housing 12; an observation window 11 is provided on one side of the first housing 12, and a concave mirror 13 is provided inside the first housing 12 corresponding to the observation window 11. The concave mirror 13 is connected to the inner wall of the first housing 12. A beam splitter 14 is provided between the concave mirror 13 and the observation window 11. The beam splitter 14 is inclined, with its lower edge 141 close to the observation window 11 and its upper edge 142 away from the observation window 11. The concave mirror 13 and the beam splitter 14 can be fixed by being fitted into a slot provided in the housing 12.

[0039] In this embodiment, the main working principle of the optical component is to transform a near-distance image into a far-distance image using optical technology, simulating the effect of looking into the distance. This technology is based on multiple refractions of light and special technical means to extend the distance of the observed object from close up to five meters or even further, thereby effectively avoiding eye strain caused by prolonged close-range use of the eyes.

[0040] As an example, the beam splitter 14 in this application has a flat plate structure and is made of coated glass. One side is a lens, similar to glass; the other side is a reflector, similar to a mirror. The beam splitter 14 is tilted and positioned to correspond to the reading material in the screen compartment 2. Part of the light emitted from the reading material is transmitted through the beam splitter 14 and propagates along the original path, while the other part of the light is reflected to the concave mirror 13. The concave mirror 13 has a concave reflective surface, which can focus the light while reflecting it. The concave mirror 13 reflects the light reflected by the beam splitter 14 back to the beam splitter 14 and transmits it outside the beam splitter 14, presenting it to the user's eyes through the viewing window 11.

[0041] To slow the progression of myopia, this application includes a defocusing lens 16 in the viewing window 11. As an example, the defocusing lens 16 in this application is as follows... Figure 7 As shown, the outer striped area 161 of the defocus lens 16 is a Fresnel lens, and the central area 162 surrounded by the Fresnel lens is a planar, concave, or convex lens, the specific choice of which depends on the user's needs. The defocus lens can be made of resin. For ease of installation, metal posts 163 are provided at the four corners of the defocus lens 16, and magnets are provided in the first housing 12 for magnetic attraction and fixation. This application utilizes the surrounding Fresnel lenses to focus some light rays onto the front of the retina, thereby mitigating the increase in axial length, slowing the progression of myopia, and also assisting in fogging training.

[0042] In some alternative implementations, refer to Figure 1An adjustment assembly is provided on the side of the first housing 12 of the observation chamber 1 opposite to the observation window 11. The adjustment assembly includes a support rod 51 fixedly connected to the screen chamber 2 and a sleeve 52 fixedly connected to the first housing 12 of the observation chamber 1. The support rod 51 and the sleeve 52 are slidably connected and lockable. The distance between the observation chamber 1 and the screen chamber is adjusted by adjusting the position of the sleeve 52 on the support rod 51. The locking between the support rod 51 and the sleeve 52 is achieved by providing a hand-tightening bolt on the sleeve 52, which is then tightened against the support rod 51.

[0043] In some alternative implementations, refer to Figure 1 , Figure 8 The screen compartment 2 includes a back plate 21 connected to the support rod 51, and the display assembly 4 is rotatably connected to the bottom of the back plate 21. The rotation of the display assembly 4 relative to the back plate 21 is primarily for two purposes: First, when used as a far-viewing screen, the display assembly 4 is parallel to the desktop, allowing for the fixation of electronic products or other reading materials; second, when used as a reading / writing station, the display assembly 4 and the back plate 21 are folded together to create space for placing reading / writing materials under the viewing compartment 1.

[0044] To facilitate its use as a reading and writing station, the back panel 21 is positioned on the side away from the observation window 11. This way, when the display assembly 4 and the back panel 21 are folded, the side of the screen compartment 2 closest to the user is an open space, making it convenient for the user to place reading materials.

[0045] In some optional embodiments, the display assembly 4 includes a display bracket 42, which has a mounting position 421 for accommodating the display screen, through which electronic reading materials such as learning machines, tablets, and mobile phones are fixed. For ease of operation, the display bracket 42 is rotatably connected to the back plate 21 and driven to rotate relative to the back plate by a first driving member.

[0046] As an example, the display assembly 4 of this application is connected to the back plate 21 by a first drive motor at one end of the pivot 41. The display assembly 4 is driven to fold relative to the back plate 21 by the first drive motor, so as to realize the automatic folding function and facilitate use.

[0047] In some optional embodiments, the display assembly 4 further includes a full-spectrum lamp 6 disposed around the mounting position 421, the full-spectrum lamp 6 being used to provide supplemental lighting for the reading material. The full-spectrum lamp 6 can be directly mounted on the display bracket 42 and disposed around the mounting position 421, or it can be disposed on the housing surrounding the display bracket 42.

[0048] In some alternative implementations, refer to Figure 1 , Figure 8 The screen compartment 2 further includes side plates rotatably connected to both sides of the back plate 21, and a second driving member 23 for driving the side plates to rotate relative to the back plate 21. For ease of description, the two side plates are named the first side plate 22a and the second side plate 22b in this embodiment. When used as a far-viewing screen, the first side plate 22a and the second side plate 22b are provided to prevent external light from interfering with the reading material. The second driving member 23 can be a motor, which drives the first side plate 22a and the second side plate 22b to rotate relative to the back plate 21. To achieve a better light-blocking effect, a third side plate 23 is also provided below the viewing window 11. The third side plate 23 is rotatably connected to the display assembly 4 and can be equipped with a motor or other driving member to realize the rotation of the third side plate 23 relative to the display assembly.

[0049] The following is combined Figure 8 This description explains the actions of each side panel when switching from the remote image display function to the reader / writer function. To achieve a better folding effect, the back panel 21 in this embodiment has a receiving cavity. First, the first side panel 22a rotates and folds into the receiving cavity, then the second side panel 22b rotates and folds into the receiving cavity, followed by the third side panel 23 rotating and folding with the display screen bracket 42, and finally the display screen bracket 42 rotating and folding with the back panel 21. When switching from the reader / writer function to the remote image display function, the sequence of actions of each side panel is the reverse of the above sequence, and will not be repeated here.

[0050] In some optional embodiments, a light-shielding plate 15 is provided below the observation window of the observation chamber 1. For ease of use, the light-shielding plate 15 is rotatably connected to the observation chamber 1 and is provided with a flipping mechanism for driving and locking the light-shielding plate. When used as a far-viewing screen, the light-shielding plate 15 flips downwards to fit against the third side panel of the screen chamber 2; when used as a reading / writing station, the light-shielding plate 15 flips upwards to be parallel or approximately parallel to the desktop, such as... Figure 4 As shown. When used as a reading and writing station, the light shield 15 can block peripheral vision and prevent the user from seeing the reading material located below the observation chamber 1 through peripheral vision. The flipping component can be an automatic flipping component such as a motor, or a manual flipping component equipped with a hand-tightening bolt for locking.

[0051] In some optional embodiments, the observation chamber 1 is provided with red lights 7 on both sides of the observation window 11. The red light emitted by the red lights 7 can relieve eye fatigue, stimulate retinal cell activity, and promote visual development, thus playing a positive role in preventing the occurrence and development of myopia. The red lights 7 can be fixed to both sides of the observation window 11 of the observation chamber 1 by means of adhesive or other methods.
