Description

Technical Field

[0001] This utility model relates to a foldable desktop remote image reading and writing device with back panel supplemental lighting. Background Technology

[0002] The problem of myopia among teenagers is becoming increasingly serious. The root cause is that teenagers' eyes spend most of their time focusing on close-up objects, causing their axial length to gradually increase in order to adapt to prolonged close-range imaging. To address this issue, various myopia prevention and control products have emerged on the market.

[0003] Among them, desktop far-image reading and writing devices are devices that use optical means to extend near-distance reading and writing to distant imaging, and are mostly used in the field of myopia prevention and control among teenagers. Foldable desktop far-image reading and writing devices are a new design developed based on box-type desktop far-image reading and writing devices (where the beam splitter and curved mirror are in relatively fixed positions). This design incorporates a rotating and folding structure for the beam splitter and curved mirror, which can save a lot of desk space when folded (when not in use).

[0004] Because desktop far-viewing readers use the Birdbath solution, the beam splitter reduces light efficiency. Therefore, users need to turn on the supplementary light of the desktop far-viewing reader to illuminate the paper when reading or doing homework, to ensure that the light emitted from the beam splitter is bright enough to reduce eye fatigue. Existing box-type desktop far-viewing readers typically have four light strips at the bottom of the device, projecting light onto the desktop from all sides. Due to structural limitations, foldable desktop far-viewing readers cannot have multiple light strips at the bottom, which poses a greater challenge in providing uniform illumination; and achieving uniform illumination is even more difficult for the smaller, more portable foldable desktop far-viewing readers. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a foldable desktop remote image reading and writing device with back panel supplemental lighting.

[0006] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:

[0007] A foldable desktop far-viewing reading and writing device with backplate supplemental lighting includes a bracket, a front shell, a rear shell, a backplate, a beam splitter, a reflector, and a supplemental light. The backplate is housed in the rear shell, and the reflector is housed in the front shell. The rear end of the rear shell is connected to the upper end of the bracket. The tops of the rear shell, the beam splitter, and the front shell are rotatably connected. The beam splitter is positioned between the backplate and the reflector. The device is characterized by:

[0008] The fill light includes one or more back panel fill light modules disposed on the surface of the back panel facing the beam splitter. When the beam splitter is opened and separated from the back panel, the back panel fill light in the back panel fill light module tilts towards the table to provide illumination to the table.

[0009] Preferably, the back panel fill light module is embedded in the back panel and includes a fill light base, a fill light cover, and a support plate located between the fill light base and the fill light cover. The support plate is tilted towards the table when the fill light cover is open, and the back panel fill light is provided on the side of the support plate facing the table.

[0010] Preferably, the top of the fill light cover plate is pivotally connected to the top of the fill light base via a first rotating shaft, and a return spring is sleeved on the first rotating shaft; the fill light support plate is pivotally connected to the middle of the fill light cover plate via a second rotating shaft, and a return spring is sleeved on the second rotating shaft; so that when the external force applied to the fill light cover plate disappears, the fill light cover plate pops out and opens, so that the back fill light faces the table.

[0011] Preferably, the fill light base is provided with a first limiting structure to limit the maximum rotation angle of the fill light cover plate relative to the fill light base; the fill light cover plate is provided with a second limiting structure to limit the maximum rotation angle of the fill light support plate relative to the fill light cover plate.

[0012] Preferably, the beam splitter applies an external force toward the fill light base to the fill light cover plate during rotation toward the back plate.

[0013] Preferably, the fill light base is provided with a protruding strip that extends toward the support plate. The extension direction of the protruding strip intersects with or is consistent with the sliding direction of the fill light support plate, so as to reduce the friction when the bottom of the support plate slides relative to the fill light base.

[0014] Preferably, the supplementary light also includes a right supplementary light and a left supplementary light disposed in the back frame of the beam splitter.

[0015] Preferably, the bracket is a foldable bracket, including a vertical lifting structure, a connecting part, and front support legs. The upper end of the vertical lifting structure is connected to the rear end of the reading and writing table's rear shell, and the connecting part is fixedly connected to the bottom end of the vertical lifting structure. Damping pivots are provided at both ends of the connecting part, and the two front support legs are hinged to the two ends of the connecting part through the damping pivots to achieve rotation relative to the vertical lifting structure, so that the front support legs can switch between a folded state parallel to the reading and writing table's rear shell and an open state perpendicular to or inclined to the reading and writing table's rear shell.

[0016] Preferably, the foldable bracket further includes a rear support leg, which is hinged to the connecting part. The rear support leg can rotate relative to the lower end of the vertical lifting structure so that the rear support leg can switch between a folded state parallel to the rear shell of the reading and writing table and an open state perpendicular to or inclined to the rear shell of the reading and writing table.

[0017] Preferably, when the vertical lifting structure is compressed to its shortest stroke, the connecting part is located near the bottom of the rear shell of the reading / writing station.

[0018] The foldable desktop image reading and writing device with back panel supplemental lighting provided by this utility model projects light onto the desktop by setting a back panel supplemental lighting module on the back panel, thereby improving the brightness and uniformity of desktop lighting. Furthermore, by combining the left and right supplemental lighting lights set on the back of the beam splitter, more uniform desktop lighting can be achieved. Attached Figure Description

[0028] The foldable desktop image reading and writing device with backplane supplementary lighting provided in this embodiment is described in reference to... Figures 1-3 As shown, the device includes a support 10, a rear shell 11 of the reading / writing station, a beam splitter 13, a front shell 12 of the reading / writing station, and a supplementary light. A back panel 14 is installed inside the rear shell 11, and a reflector is installed inside the front shell 12. The rear end of the rear shell 11 is connected to the upper end of the support 10. The tops of the rear shell 11, beam splitter 13, and front shell 12 are rotatably connected. The beam splitter 13 is positioned between the reflector and the back shell 14. By flipping up the front shell 12 and rotating the beam splitter 13 to a predetermined position, the foldable reading / writing station can be opened. At this point, turning on the supplementary light allows for normal use. This foldable reading / writing station can create a magnified and amplified virtual image of books or monitors on a desktop, with a distance of 3-8 meters, thus solving the problem of prolonged close-range eye use. The working principle of the main body of the reading / writing station is not described in detail in this embodiment.

[0029] like Figure 3 As shown, in this folding reading and writing table, the supplementary light includes one or more back panel supplementary lights 16 disposed on the side of the back panel 14 of the reading and writing table facing the beam splitter 13. When the beam splitter 13 is opened to separate the beam splitter 13 from the back panel 14 of the reading and writing table, the back panel supplementary lights 16 tilt towards the tabletop to provide illumination to the tabletop.

[0030] Reference Figures 4-5As shown, specifically, the folding reading and writing desk includes a back panel fill light module 15, which is embedded in the back panel 14 of the reading and writing desk. The back panel fill light module 15 includes a fill light base 21, a fill light cover 22, and a fill light support plate 23 located between the fill light base 21 and the fill light cover 22. A back panel fill light 16 is provided on the side of the fill light support plate 23 facing the desktop. The top end of the fill light base 21 and the top end of the fill light cover 22 are pivotally connected by a rotating shaft 24 located at the top, and a return spring 25 is sleeved on the rotating shaft 24 located at the top; one end of the fill light support plate 23 is pivotally connected to the middle of the fill light cover 22 by a rotating shaft 24 located in the middle, and the other end can slide in the fill light base 21, and a return spring 25 is sleeved on the rotating shaft 24 located in the middle; so that when the external force applied to the fill light cover 22 disappears, the fill light cover 22 pops out and opens, and the fill light support plate 23 and the back plate fill light 16 set thereon tilt towards the table when the fill light cover 22 is opened.

[0031] Furthermore, the fill light base 21 is provided with a first limiting structure to limit the maximum rotation angle of the fill light cover plate 22 relative to the fill light base 21; the fill light cover plate 22 is provided with a second limiting structure to limit the maximum rotation angle of the fill light support plate 23 relative to the fill light cover plate 22.

[0032] During the rotation of the beam splitter 13 toward the back plate 14, an external force is applied to the fill light cover 22 toward the fill light base 21. Under the action of the external force, the fill light cover 22 rotates toward the fill light base 21, compresses the return spring 25, and drives the lower end of the fill light support plate 23 to slide inside the fill light base 21, thereby housing the fill light support plate 23 and the back plate fill light 16 inside the fill light base 21.

[0033] Reference Figure 2 and Figure 3 When the beam splitter 13 is opened, the fill light cover 22 automatically pops out under the action of the two reset springs 25, and the fill light support plate 23 rotates relative to the fill light cover 22, so that the back fill light 16 tilts to face the table.

[0034] In a preferred embodiment, the fill light base 21 is provided with multiple protrusions protruding towards the support plate 23. The extension direction of the protrusions intersects or coincides with the sliding direction of the fill light support plate 23, thereby changing the friction during the sliding process of the fill light support plate 23 from line friction to multi-point friction, so as to reduce the friction force when the bottom of the support plate slides relative to the fill light base.

[0035] Reference Figure 5As shown, in this embodiment, the supplementary light also includes a right supplementary light 17 and a left supplementary light 18 disposed in the back frame of the beam splitter 13. The left and right supplementary lights use LED lights in the prior art, and their color temperature is between 3000K and 5500K.

[0036] One or more back panel fill lights 16, right-side fill lights 17, and left-side fill lights 18 are controlled by the same control circuit to achieve simultaneous illumination of all three. For example, a second sensor is provided at the front of the back panel 14 of the reader / writer, and a first sensor is provided on the beam splitter 13 at a position corresponding to the second sensor. In this embodiment, the first sensor can be a magnet, and the second sensor is a Hall sensor. The first sensor, the second sensor, the back panel fill lights 16, the right-side fill lights 17, and the left-side fill lights 18 are all connected to the main board. The first and second sensors sense the separation of the beam splitter 13 from the back panel 14 of the reader / writer and send a switch signal to the main board, which then controls the automatic activation of all fill lights.

[0037] When the beam splitter 13 is opened, separating it from the back panel 14 of the reader / writer, the separation triggers the second sensor to output a first switch signal, controlling the auxiliary light to turn on. When the beam splitter 13 is closed, fitting together with the back panel 14, the fitting together triggers the second sensor to output a second switch signal, controlling the auxiliary light to turn off. Thus, the opening and closing of the beam splitter 13 and the back panel 14 controls the auxiliary light's on / off state. This eliminates the need for manual operation of the auxiliary light when the reader / writer itself needs to be opened or closed, making the operation more convenient.

[0038] In this embodiment, the bracket 10 preferably uses a foldable bracket, which includes a vertical lifting structure 30 and a foldable base. The upper end of the vertical lifting structure 30 is connected to the rear end of the reading and writing table rear shell 11. The vertical lifting structure 30 connects the rear end of the reading and writing table rear shell 11 to the upper part of the foldable base, so that the height of the reading and writing table rear shell 11 above the foldable bracket can be adjusted to meet the adjustment requirements of a certain height range of the reading and writing table body.

[0039] Reference Figure 6 As shown, specifically, the vertical lifting structure 30 includes a slide rail 31 and a slide groove 32. The slide rail 31 or slide groove 32 is vertically fixed to the center of the rear end of the reading and writing table rear shell 11. One end of the slide rail 31 is slidably installed in the slide groove 32. There is damping between the slide rail 31 and the slide groove 32, so that the slide rail 31 and the slide groove 32 will slide relative to each other only when an external force is applied. The foldable bracket can be detached from the rear end of the reading and writing table rear shell 11 and separated from the whole machine as a separate module for easy carrying.

[0040] When the vertical lifting structure 30 is compressed to its shortest stroke, the foldable base is close to the bottom of the reading and writing table's rear shell 11. At this time, the foldable bracket can be folded. With this structural design, the foldable bracket does not need to be removed separately from the rear end of the reading and writing table's rear shell 11, and it is also easy to carry.

[0041] The foldable base includes a connecting part 34, front support legs 35, and rear support legs 36. The connecting part 34 is fixedly connected to the bottom end of the vertical lifting structure 30, and damping pivots 37 are provided at both ends of the connecting part 34. The foldable base includes at least two front support legs 35, which are hinged to both ends of the connecting part 34 via the damping pivots 37. The front support legs 35 can rotate relative to the lower end of the vertical lifting structure in a first rotation direction (see reference). Figure 6 The directions shown are clockwise) and the second rotation direction (reference). Figure 6 The front support leg 35 can be rotated (in a counter-clockwise direction) to switch between a folded state parallel to the rear shell 11 of the reader / writer and an open state perpendicular to the rear shell 11. The two front support legs 35 can move in tandem. The front support leg 35 can rotate no more than 270 degrees relative to the lower end of the vertical lifting structure 30 along a first rotation direction to be in the open state. When the front support leg 35 rotates to be parallel to the vertical lifting structure 30, the front support leg 35 folds and retracts when the vertical lifting structure 30 is compressed to its shortest stroke.

[0042] The foldable base also includes a rear support leg 36, which is positioned relative to the lower end of the vertical lifting structure 30 along a third rotation direction and a fourth rotation direction (see reference). Figure 6 The directions shown represent opposite directions of rotation within the horizontal plane. Rotation allows switching between the folded and open states. The rear support leg 36 can rotate no more than 180 degrees (e.g., 90 degrees), and in the open state, the rear support leg 36, together with the two open front support legs 35, forms a support relative to the tabletop. The rear support leg 36 is hinged to the connecting part 34, and its rotation is damped. When not in use, the rear support leg 36 can be rotated to the storage space 38 below the connecting part 34, for example, by magnetically attaching to the back of the connecting part 4.

[0043] In addition to rotating in the horizontal plane, the rear support leg 36 can also rotate in the opposite direction to the front support leg 35, achieving a rotation of no more than 270 degrees, thus working together with the front support leg 35 to form a stable support. For example, when providing support, the two front support legs 35 can be rotated 270 degrees in the first rotation direction to reach the horizontal, and the rear support leg 36 can be rotated 270 degrees in the second rotation direction to reach the horizontal. By using the cooperation of the front support leg 35 and the rear support leg 36 for support, the reading and writing table is supported more stably.

[0044] This utility model discloses a portable foldable reading and writing table. In use, the front support leg 35 and the rear support leg 36 cooperate to provide stable support for the reading and writing table. The front support leg 35, the rear support leg 36 and the connecting part 34 can all rotate so that they are on the same plane as the slide rail 31. At this time, the vertical lifting structure is compressed to the shortest stroke, so that the foldable bracket is close to the bottom of the rear shell 11 of the reading and writing table, making the size of the reading and writing table smaller after folding, thus making it easy to store and carry.

[0045] The foregoing has provided a detailed description of the foldable desktop image reading and writing device with backplate supplementary lighting provided by this utility model. Any obvious modifications made by those skilled in the art without departing from the essential content of this utility model will constitute an infringement of the patent rights of this utility model and will incur corresponding legal liability.
