It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0038] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0039] Examples, such as Figures 1-11As shown, a modular height-adjustable study desk includes a desk body 1, a desk lifting frame 2, a desktop component 3 and a partition component 4 above the desk lifting frame 2, a lighting component 5 on the partition component 4, and a learning component 6 on the desktop component 3. The desk lifting frame 2 can be adjusted vertically to accommodate people of different heights and improve the functionality of the device. The partition component 4 can divide the study area into zones to reduce interference. The lighting component 5 can provide lighting conditions for people to study and ensure the learning effect. The learning component 6 allows people to adjust its viewing angle according to different needs, improving its practicality.

[0040] Furthermore, the table lifting frame 2 includes lifting table legs 21. A top beam 22 is provided above the two lifting table legs 21 for connection. A connecting beam 23 is also provided between the two lifting table legs 21. A diagonal brace 24 is provided on the outside of the connecting beam 23. The composition of the table lifting frame 2 provides good stability and improves practicality during subsequent use. Furthermore, the lifting table legs 21 include an upper table leg 211, a lower table leg 212, and a lifting mechanism 213 and a guide member 214 disposed inside the upper table leg 211 and the lower table leg 212. As described above, the guide member 214 is sleeved on the lower outer side of the upper table leg 211, allowing it to slide vertically relative to the inner side wall of the lower table leg 212. When the lifting mechanism 213 is running, it acts on the upper table leg 211 to cause relative sliding, thereby completing the convenient adjustment of the height of the study table body 1 to meet the usage needs.

[0041] To improve the rationality of the device's design, the desktop assembly 3 includes a horizontally designed flat tabletop 31 located in the center and a sloping tabletop 32 located on one side of the flat tabletop 31. The lower side of the sloping tabletop 32 is securely connected to the inclined support frame 24. Furthermore, the tilt angle between the sloping tabletop 32 and the flat tabletop 31 ranges from 5° to 15°. Any angle within the aforementioned tilt angle range is relatively ergonomic for use as a study desk. To ensure the use of pens during study, a pen guard strip 321 is provided at the lower edge of the sloping tabletop 32 to prevent pens from falling and causing damage. To ensure comfort during long study sessions, i.e., to provide support for the arms, an arc-shaped recess 322 is provided at the front edge of the sloping tabletop 32 to support the elbows.

[0042] To ensure the functionality of the study table body 1, a set of table lifting frame 2, desktop component 3 and partition component 4 constitutes a single table body 7 facing each other. Multiple single table bodies 7 can be side-joined by the table lifting frame 2. After joining multiple single table bodies 7 as described above, the study table body 1 can be expanded into a combination of 2N people, meeting the needs of a large number of people. It is also convenient for people to arrange and combine according to actual needs. The operation is simple and convenient, and it is highly practical.

[0043] To further ensure learning effectiveness, the lighting component 5 includes a health-protecting eye lamp 51 mounted on the partition component 4. A human detection sensor 52 can be installed within the health-protecting eye lamp 51 to detect human presence and control the lamp's on / off state. The health-protecting eye lamp 51 includes an adjustable lamp holder 53 and a lamp head 54 at the end of the adjustable lamp holder 53. It should be further noted that the folding adjustment position of the adjustable lamp holder 53 is established by a hinge, ensuring free adjustment during use and thus guaranteeing the lighting effect. The lamp head 54 generally consists of an LED light strip, an LED illuminance and color temperature adjustment control device 541, a light-transmitting plate 542, and a human detection sensor 52. When the LED light strip is running, the light beam is guided through the light-transmitting plate 542 and acts on the desktop component 3 to achieve the purpose of illumination. The LED illuminance and color temperature adjustment control device 541 allows for easy adjustment according to different usage needs, achieving diversified lighting. The human detection sensor 52 ensures that the light is turned off when a person leaves or when a person arrives. Turning on the light, of course, for the lighting components used in this embodiment, intelligent lighting fixtures can also be adopted. For example, people can conveniently adjust the light using physical buttons on the lighting components, and can also cooperate with the learning tablet 63 in the learning component 6 to achieve intelligent adjustment during the lighting process. Furthermore, the mounting end of the adjustable lamp holder 53 is hinged to one side of the partition 42, and the power cord of the eye-protecting lamp 51 passes through the adjustable lamp holder 53 and is electrically connected to the power socket 43 to ensure that the lighting component 5 has sufficient power to supply its operation. In addition, in order to ensure that users can meet their requirements in reading and writing scenarios, the lighting component 5 also includes an LED illuminance and color temperature adjustment control device for reading and writing scenarios. The aforementioned LED illuminance and color temperature adjustment control device for reading and writing scenarios can be used for specific reading and writing scenarios. The previously mentioned LED light strip and LED illuminance and color temperature adjustment control device 541 meet people's daily lighting needs and greatly improve the functionality of the device.

[0044] To further enhance the functionality of the device, especially to facilitate the placement of learning equipment on the study desk, the learning component 6 includes an adjustable bracket 61. A book clamping plate 62 is provided at the end of the adjustable bracket 61, and a learning tablet 63 is placed on the book clamping plate 62. This learning tablet 63 is a conventional intelligent integrated learning tablet 63. For example, an AI camera 64 can be installed on the learning tablet 63, and several AI software programs, such as Doubao and DeepSeek, can be installed on the operating system of the learning tablet 63, facilitating users to access information and improve learning efficiency. Alternatively, the intelligent learning tablet 63 can be equipped with software for controlling lighting, allowing users to physically control the lighting system and also intelligently control it using the learning tablet 63, thus improving practicality. Of course, the intelligent integrated learning tablet 63 mentioned in this embodiment... The learning tablet 63 is not limited to information retrieval and light control; it can also be used in conjunction with other functions such as table height adjustment. When the learning tablet 63 is not in use, it can be used to hold books. By removing the learning tablet 63, the book clips 621 on both sides of the book clip 62 can be extended and retracted. The book clips 621 can be pulled out and held according to actual needs, achieving multi-functional use. The book clip 62 is fixed to the flat tabletop 31 by an adjustable bracket 61. When in use, the position of the book clip 62 can be freely adjusted using the folding structure of the adjustable bracket 61, which can meet people's needs.

[0045] To make the study desk more convenient to use and reduce interference between adjacent seats, the partition assembly 4 includes an adjacent partition 41 for separating adjacent seats and an overpass partition 42 for separating seats across from each other. Furthermore, the overpass partition 42 is vertically arranged between the flat tabletop 31 and the top beam 22. In addition, the adjacent partition 41 is located on one side of the overpass partition 42 and is arranged perpendicular to the overpass partition 42 and the desktop assembly 3. A power socket 43 is provided on the overpass partition 42 located on one side of the adjacent partition 41. This design can provide power to the eye-protection lamp 51 and the learning tablet 63, etc., to meet the usage needs.

[0046] The table frame is height-adjustable, primarily achieved through the lifting legs 21. The lifting of the legs is accomplished by the lifting mechanism 213. Therefore, to ensure convenient vertical adjustment of the table frame 2, the lifting mechanism 213 is one of a gas spring, an electric actuator, or a lead screw 83 and nut 82 transmission device 8. All of these devices can achieve vertical lifting. In this embodiment, the lead screw 83 and nut 82 transmission device 8 is used as an example. The lead screw 83 and nut 82 transmission device 8 includes a reversing gearbox 81, a nut 82, and a through-type gearbox. The screw 83 passes through the nut 82 and the extension tube 84 is located below the nut 82. The reversing gearbox 81 is securely fixed to the inner side of the upper table leg 211. The reversing gearbox 81 has at least one power input end 811 and two power output ends 812. Its function is that when manually raising or lowering, the hand crank can be inserted into the power input end 811, and the two power output ends 812 of the reversing gearbox 81 will switch the power, one of which outputs rotational power to the screw 83. The rotating screw 83 drives the nut 82 to move up and down, and the nut 82 and its extension tube 84... The lower end of the long tube 84 is fastened inside the lower table leg 212. The up-and-down movement force of the nut 82 reacts to the gearbox, thereby causing the gearbox to drive the upper table leg 211, which is fastened to it, to rise. The other power output end 812 of the gearbox in the horizontal direction transmits the rotational force to the gearbox power input end 811 of the lifting mechanism 213 of the other lifting table leg 21. Similarly, the lifting mechanism 213 of the other lifting table leg 21 also rises and falls synchronously. Under the above operation, the lifting table leg 21 can be easily adjusted vertically to meet different user needs. For this embodiment... The reversing gearbox 81 submitted in the patent application can be compared with the gearbox structure mentioned in the utility model patent document published by the State Intellectual Property Office: a gearbox with both tabletop tilt and height adjustment {Patent No.: CN202420173551.7} or a front hand crank device for lifting and lowering a study desk {Patent No.: CN202220869129.6}. In addition, its lifting and lowering process can be referred to the following documents. Its specific working principle and working method will not be repeated here, and can be effectively understood by those skilled in the art.

[0047] To ensure sufficient power consumption when multiple students are using the study desk, the partition 42 is optimized. In addition to a single board without a cavity partition, the partition can be designed as a cavity partition. This cavity partition can also be equipped with a cable tray for high-power power supply wiring when multiple students are using the desk. Furthermore, to ensure that the sound does not disturb each other when multiple students are using the study desk, the selected partition uses sound-insulating materials. Specifically, it can be one or more of the following materials: sponge-covered board, elastic plastic board, steel perforated board, plastic perforated board, paulownia board, and kapok board, to meet different usage needs.

[0048] In the above process: the table lifting frame 2 can be adjusted vertically to accommodate people of different heights, improving the functionality of the device; the partition component 4 can divide the study area into zones to reduce interference; the lighting component 5 provides lighting conditions for people to study, ensuring learning effectiveness; and the learning component 6 allows people to adjust its viewing angle according to different needs, improving practicality. In other words, the modular table integrates eye-protection lighting, device power supply, tablet stand, and switchable tilt tabletop, using partitions to separate adjacent seats to reduce interference; the lifting table legs are adapted to different heights, and multiple units can be freely spliced ​​and expanded, making it suitable for scenarios such as libraries and study rooms. This device is reasonably designed, simple in structure, easy to process, and integrates lighting, power supply, and multi-angle adjustable support functions, while planning independent study areas to reduce interference. At the same time, the device height can be conveniently adjusted to improve its functionality and meet different usage needs.

[0049] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
