Technical Field
[0001] This utility model relates to the field of reading and writing station technology, and in particular to a folding reading and writing station with an automatic on / off auxiliary light. 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 eyeballs to gradually lengthen in order to adapt to near-field imaging. Reading and writing stations, which use optical means to extend near-field reading and writing to far-field imaging (the Birdbath solution, which includes a beam splitter and a curved mirror), have been increasingly used in the field of myopia prevention and control among teenagers in recent years.
[0003] The folding reading desk is a new design developed from the box-type reading desk (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, saving significant desk space when folded (when not in use). However, the folding and closing action itself adds an extra step for the user each time they use the desk.
[0004] Because the folding reading desk uses the Birdbath system, the beam splitter reduces light efficiency. Therefore, users need to turn on the desk's supplemental light when reading or doing homework to ensure sufficient brightness of the light emanating from the beam splitter, thus reducing eye strain. Traditional reading desk designs require pressing a button (or other operations, such as touch) to turn the supplemental light on and off. Given that the folding desk itself requires opening and closing, the additional operation of turning the light on and off becomes cumbersome and inconvenient for users. Utility Model Content
[0005] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a folding reading and writing table that automatically turns on and off the supplementary light. Under the premise that the folding reading and writing table itself needs to open or close the beam splitter, it can automatically control the opening and closing of the supplementary light, making its operation more convenient.
[0006] This utility model is achieved using the following technical solution: a folding reading and writing table with an automatic opening and closing fill light, comprising a bracket, a back plate, a beam splitter, a reading and writing table cover, and a fill light. The rear end of the back plate is connected to the upper end of the bracket. The tops of the back plate, beam splitter, and reading and writing table cover are rotatably connected. The beam splitter is disposed between the back plate and the reading and writing table cover. A second sensor is disposed at the front of the back plate, and a first sensor is disposed on the beam splitter at a position corresponding to the second sensor. When the beam splitter is opened, separating it from the back plate, the first sensor and the second sensor will separate due to the separation. The second sensor is triggered to output a first switch signal, controlling the fill light to turn on; when the beam splitter is closed, so that the beam splitter is attached to the back panel, the first sensor and the second sensor will be attached together, triggering the second sensor to output a second switch signal, controlling the fill light to turn off; thus, the opening and closing of the beam splitter and the back panel controls the switching of the fill light; the fill light includes one or more back panel fill light modules disposed on the side of the back panel facing the beam splitter, when the beam splitter is opened and the beam splitter is separated from the back panel, the back panel fill light in the back panel fill light module tilts towards the table, providing illumination to the table.
[0007] Furthermore, the back panel fill light module is embedded in the back panel and includes a fill light base, a fill light cover, and a fill light support plate located between the fill light base and the fill light cover. The fill light 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 fill light support plate facing the table.
[0008] Furthermore, the top of the fill light cover plate is pivotally connected to the top of the fill light base, and a return spring is sleeved on the rotating shaft; the fill light support plate is pivotally connected to the middle of the fill light cover plate via the rotating shaft, and a return spring is sleeved on the 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 panel fill light faces the table.
[0009] Furthermore, the base of the fill light 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.
[0010] Furthermore, the supplementary lighting also includes a right supplementary lighting and a left supplementary lighting disposed in the back frame of the beam splitter.
[0011] Furthermore, a main board is installed inside the back panel. The main board is connected to the second sensor and all the fill lights via wires, and receives the switching signals from the second sensor to control the switching of all the fill lights.
[0012] Furthermore, a distance sensor is also installed on the front of the back panel. The distance sensor is connected to the motherboard via a wire. The distance sensor triggers and outputs different switching signals when the beam splitter is attached to or separated from the back panel, which are used to control the switching of all the fill lights.
[0013] Furthermore, the back panel is also equipped with a button board, which is connected to the main board via wires. The main board receives the switch signals from the button board to control the on and off of all fill lights.
[0014] Furthermore, a display screen is also provided on the front of the back panel. The display screen is connected to the motherboard via wires, and the motherboard controls the display screen to display parameters related to the fill light.
[0015] Furthermore, the first sensing element is a magnet, and the second sensing element is a Hall sensor.
[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0017] 1. This utility model discloses a folding reading and writing table with an automatic on / off auxiliary light. When the beam splitter is opened to separate it from the back panel, the first and second sensors will trigger a switch signal due to the separation, which will control the auxiliary light to turn on via the main board. When the beam splitter is closed to fit against the back panel, the second sensor will trigger a switch signal due to the fitting to control the auxiliary light to turn off. Thus, the folding reading and writing table no longer needs to operate the auxiliary light to turn on or off when it needs to open or close the beam splitter, making its operation more convenient.
[0018] 2. This utility model discloses a folding reading and writing station with an automatic on / off auxiliary light. A distance sensor installed on the front of the back panel triggers different switching signals when the beam splitter is attached to or separated from the back panel. The main board controls the on / off of the auxiliary light, making operation more convenient. After the auxiliary light is automatically turned on, it can be manually turned off via the button panel if the user does not need it to be turned on. Attached Figure Description

It should be noted that, unless otherwise specified, the following embodiments and features described therein can be combined with each other.
[0026] The purpose of this invention is to address the shortcomings of existing technologies by providing a folding reading and writing station that automatically turns on and off the supplementary lighting.
[0027] Example 1
[0028] This embodiment provides a folding reading and writing station that automatically turns on and off the supplementary light, referring to... Figures 1-2 As shown, the device includes a support 1, a reader / writer backplate 2, a beam splitter 3, a reader / writer cover 4, and a supplementary light. The rear end of the reader / writer backplate 2 is connected to the upper end of the support 1. The tops of the reader / writer backplate 2, beam splitter 3, and reader / writer cover 4 are rotatably connected. The beam splitter 3 is positioned between the reader / writer backplate 2 and the reader / writer cover 4. A second sensor 23 is provided at the front of the reader / writer backplate 2. A first sensor 22 is provided on the beam splitter 3 at a position corresponding to the second sensor 23. In this embodiment, the first sensor 22 can be a magnet, and the second sensor 23 is a Hall sensor.
[0029] When the beam splitter 3 is opened, causing it to separate from the back panel 2 of the reader / writer, the separation of the first sensor 22 and the second sensor 23 will trigger the second sensor 23 to output a first switch signal, controlling the fill light to turn on.
[0030] When the beam splitter 3 is closed and attached to the back panel 2 of the reading and writing station, the first sensor 22 and the second sensor 23 will be triggered by the attachment, and the second sensor 23 will output a second switch signal to control the auxiliary light to turn off. Thus, the opening and closing of the beam splitter 3 and the back panel 2 of the reading and writing station will control the switch of the auxiliary light. Under the premise that the folding reading and writing station itself needs to be opened or closed, there is no need to operate the light to turn on or off separately, making the operation more convenient.
[0031] Reference Figures 1-2 As shown, the supplementary lighting includes a right supplementary lighting 27 and a left supplementary lighting 28 disposed in the back frame 5 of the beam splitter 3. The left and right supplementary lighting uses LED lights in the prior art, with a color temperature of 3000K to 5500K.
[0032] Example 2
[0033] This embodiment provides a folding reading and writing table with an automatic on / off fill light, including a support 1, a reading and writing table back plate 2, a beam splitter 3, a reading and writing table cover plate 4, and a fill light. The rear end of the reading and writing table back plate 2 is connected to the upper end of the support 1. The tops of the reading and writing table back plate 2, the beam splitter 3, and the reading and writing table cover plate 4 are rotatably connected. The beam splitter 3 is disposed between the reading and writing table back plate 2 and the reading and writing table cover plate 4.
[0034] Reference Figures 3-4 As shown, Among them, the fill lights It includes one or more back panel fill lights 36 disposed on the side of the back panel 2 of the reading and writing table facing the beam splitter 3. When the beam splitter 3 is opened and separated from the back panel 2 of the reading and writing table, the back panel fill lights 36 are tilted towards the table to provide illumination to the table.
[0035] Reference Figures 3-4 As shown, specifically, the folding reading and writing table includes a back panel fill light module 6, which is embedded in the back panel 2 of the reading and writing table. The back panel fill light module 6 includes a fill light base 31, a fill light cover plate 32, and a fill light support plate 33 located between the fill light base 31 and the fill light cover plate 32.

The top end of the fill light base 31 is pivotally connected to the top end of the fill light front shell 32, and a return spring 35 is sleeved on the rotating shaft 34; one end of the fill light support plate 33 is pivotally connected to the middle of the fill light front shell 32 through the rotating shaft 34, and the other end can slide inside the fill light base 31, and a return spring 35 is sleeved on the rotating shaft 34; so that when the external force applied to the fill light front shell 32 disappears, the fill light front shell 32 pops out and opens, and the fill light support plate 33 and the back plate fill light 36 set thereon tilt towards the table when the fill light front shell 32 is opened.
[0036] The fill light base 31 is provided with a first limiting structure to limit the maximum rotation angle of the fill light cover plate 32 relative to the fill light base 31; the fill light cover plate 32 is provided with a second limiting structure to limit the maximum rotation angle of the fill light support plate 33 relative to the fill light cover plate 32.
[0037] During the rotation of the beam splitter 3 toward the back plate 2, an external force is applied to the fill light cover 32 toward the fill light base 31. Under the action of the external force, the fill light front shell 32 rotates toward the fill light base 31, compresses the return spring 35, and drives the lower end of the fill light support plate 33 to slide inside the fill light base 31, thereby storing the fill light support plate 33 and the back plate fill light 36 inside the fill light base 31.
[0038] Reference Figure 3 When the beam splitter 3 is opened, the front cover 32 of the fill light automatically pops out under the action of the two reset springs 35, and the fill light support plate 33 rotates relative to the front cover 32 of the fill light, so that the back fill light 36 tilts to face the table.
[0039] Example 3
[0040] This embodiment provides a folding reading and writing station that automatically turns on and off the supplementary light, referring to... Figures 1-5 As shown, it includes a bracket 1, a reading / writing table back panel 2, a beam splitter 3, a reading / writing table cover 4, and a fill light.

[0041] Reference Figures 1-2 As shown, the fill lights include a right fill light 27 and a left fill light 28 disposed in the rear frame 5 of the beam splitter 3.
[0042] Reference Figures 3-4 As shown, the supplementary lighting also includes one or more back panel supplementary lighting lamps 36 disposed on the side of the back panel 2 of the reading and writing table facing the beam splitter 3. When the beam splitter 3 is opened and separated from the back panel 2 of the reading and writing table, the back panel supplementary lighting lamps 36 tilt towards the tabletop to provide illumination to the tabletop. Specifically, the folding reading and writing table includes a back panel supplementary lighting module 6, which is embedded in the back panel 2 of the reading and writing table. The back panel supplementary lighting module 6 includes a supplementary lighting base 31, a supplementary lighting cover 32, and a supplementary lighting support plate 33 located between the supplementary lighting base 31 and the supplementary lighting cover 32. The supplementary lighting support plate 33 tilts towards the tabletop when the supplementary lighting cover 32 is opened, and the back panel supplementary lighting lamps 36 are disposed on the side of the supplementary lighting support plate 33 facing the tabletop.
[0043] The above describes the light source arrangement of the folding reading and writing station through several embodiments. (Refer to...) Figures 1-5 As shown, a motherboard 21 is installed inside the back panel 2 of the read / write station. The motherboard 21 is connected to the second sensor 23 and all the fill lights via wires, and receives the switching signals from the second sensor 23 to control the switching of all the fill lights.

The second sensor 23 can use an A3144EUA-T type unipolar Hall effect switch sensor with a wide operating voltage range of 4.5~24VDC, open collector digital output, and low response time.
[0044] Reference Figures 1-5 As shown, a keypad 25 is also installed on the rear edge of the back panel 2 of the reading and writing station. The keypad 25 is connected to the main board 21 via wires. The main board 21 receives the switch signals from the keypad 25 to control the on and off of all fill lights. After the fill lights are automatically turned on, if the user does not need to turn them on, they can manually turn them off via the keypad 25.
[0045] Reference Figures 1-5 As shown, a distance sensor 24 is also installed on the front of the back panel 2 of the reader / writer. The distance sensor 24 is connected to the main board 21 via a wire. The distance sensor 24 triggers different switching signals when the beam splitter 3 is attached to or separated from the back panel 2 of the reader / writer, which are used to control the switching of all the supplementary lights. In this embodiment, the distance sensor 24 operates at a voltage of 5-24VDC and has a sensing range of not less than 5-20cm. The main board 21 receives the switching signals from the distance sensor 24 and controls the switching of the supplementary lights.

The display screen 26 is connected to the main board 21 via wires. The main board 21 controls the display screen 26 to display parameters such as the color temperature of the lamps related to the supplementary lighting. In this embodiment, the display screen 26 can be a 2.0-inch TFT LCD screen with a resolution of not less than 240*296 pixels.
[0047] Traditional folding reading and writing desks require pressing buttons or touching the screen to turn the supplementary light on and off, which is rather cumbersome.
[0048] This utility model discloses a folding reading and writing table with an automatic on / off auxiliary light. In one embodiment, when the beam splitter 3 is opened to separate from the back panel 2 of the reading and writing table, the first sensor 22 and the second sensor 23 will trigger a switch signal due to the separation, which will control the auxiliary light to turn on via the main board 21. When the beam splitter 3 is closed to fit against the back panel 2 of the reading and writing table, the second sensor 23 will output a switch signal due to the fit to control the auxiliary light to turn off. Thus, under the premise that the operation of the folding reading and writing table itself requires opening or closing the beam splitter 3, there is no need to operate the auxiliary light to turn on or off separately, making the operation more convenient.
[0049] In another scheme, the distance sensor 24 installed on the front of the back panel 2 of the reader can trigger different switching signals when the beam splitter 3 is attached to or separated from the back panel 2 of the reader, and control the switching of the fill light through the main board 21.
[0050] Of course, after the fill light is automatically turned on, if the user does not need to turn on the fill light, they can manually turn it off via the button panel 25.
[0051] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
