Description

Technical Field

[0001] This utility model relates to the field of smart home, and in particular to a smart adjustable study table. Background Technology

[0002] In today's education field, with increasing attention paid to students' physical and mental health and learning efficiency, the human-centered design and functionality of study desks, as an important learning aid, are receiving increasing emphasis. However, traditional study desks on the market generally suffer from a significant technical problem regarding height adjustment: they cannot accurately and automatically adjust to the distance between the student's thighs and the bottom of the desk.

[0003] Traditional study desks mostly rely on manual knobs or levers for height adjustment, requiring users to manually adjust the desk legs through trial and error to achieve a relatively comfortable sitting posture. This method is not only cumbersome but also makes it difficult to ensure that each adjustment precisely meets the individual needs of the student. More importantly, students' height and leg length change with age, and traditional study desks cannot capture and respond to these subtle physiological changes in real time. This can lead to health problems such as spinal curvature and vision loss due to improper posture during long study sessions. Furthermore, if the distance between the thighs and the bottom of the desk is too small, it restricts leg movement, causing poor blood circulation and discomfort.

[0004] Therefore, it is necessary to provide an intelligent adjustable study desk that can effectively adjust the desktop height and improve the convenience of desktop adjustment. Utility Model Content

[0005] The purpose of this invention is to provide an intelligent adjustable study desk that can effectively adjust the desktop height and improve the convenience of desktop adjustment.

[0006] According to one aspect of this application, a smart adjustable study desk is provided for maintaining the distance between the user's legs and the desktop, the study desk comprising:

[0007] The height adjustment section is provided with table legs that are slidably connected to the height adjustment section, and the table legs slide along the height adjustment section in the vertical direction;

[0008] A support part is fixedly connected to the height adjustment part and is located on the side of the height adjustment part away from the table legs;

[0010] The height adjustment unit is further provided with a first slide groove rotatably connected to the table leg and a second slide groove rotatably connected to the height adjustment unit. A spring is connected between the first slide groove and the second slide groove, and the first slide groove is slidably connected to the second slide groove. The height adjustment unit slides the table leg according to the image, and the spring contracts or stretches, and the first slide groove and the second slide groove rotate around the height adjustment unit respectively.

[0011] More preferably, the study desk also includes:

[0012] The desktop is fixedly connected to the two support parts and is located on the side of the support parts away from the height adjustment part;

[0013] When the table legs slide vertically, the support also moves vertically, and the tabletop also moves vertically.

[0014] More preferably, when viewed along a first surface parallel to the tabletop, the table legs, the height adjustment section, the support section, and the tabletop are arranged in sequence.

[0015] More preferably, the height adjustment part is also integrally formed with a cavity. When the table leg slides along the height adjustment part in the vertical direction and the table leg retracts, the table leg slides into the cavity. When viewed in a direction parallel to the first surface, the table leg partially overlaps with the height adjustment part.

[0016] More preferably, the surface of the support portion is referred to as the second surface, and when viewed along a direction parallel to both the first surface and the second surface, the two support portions are parallel to each other.

[0019] The first slide rotates around the first fixing pin, and the second slide rotates around the second fixing pin.

[0020] More preferably, when viewed along a direction parallel to the first surface, when the table leg slides vertically along the height adjustment section and the table leg shortens,

[0021] The first slide rotates about a first direction, and the second slide rotates about a first direction, while the spring contracts.

[0022] More preferably, when viewed along a direction parallel to the first surface, when the table leg slides vertically along the height adjustment section and the table leg extends,

[0023] The first slide rotates about a second direction, and the second slide rotates about a second direction, and the spring is stretched.

[0039] Please refer to Figure 1 - Figure 7 One embodiment of this application provides an intelligent adjustable study desk 100 for maintaining the distance between the user's legs and the desktop 40. The study desk 100 includes: a height adjustment part 10, a support part 20, and a camera 30.

[0040] The height adjustment unit 10 is provided with table legs 11 slidably connected to the height adjustment unit 10, and the table legs 11 slide vertically along the height adjustment unit 10. The support unit 20 is fixedly connected to the height adjustment unit 10 and is located on the side of the height adjustment unit 10 opposite to the table legs 11. The camera 30 is fixedly connected to the support unit 20 and electrically connected to the support unit 20. The camera 30 captures an image of the study table 100 horizontally below to obtain the distance between the user's legs and the desktop 40 and drives the height adjustment unit 10. The height adjustment unit 10 is also provided with a first slide groove 12 rotatably connected to the table leg 11 and a second slide groove 13 rotatably connected to the height adjustment unit 10. A spring 14 is connected between the first slide groove 12 and the second slide groove 13, and the first slide groove 12 is slidably connected to the second slide groove 13. The height adjustment unit 10 slides the table leg 11 according to the image, and the spring 14 contracts or extends. The first slide groove 12 and the second slide groove 13 rotate around the height adjustment unit 10 respectively.

[0041] The table leg 11 slides vertically along the height adjustment section 10, directly adjusting the height of the desktop 40. The sliding connection design is simple and reliable, suitable for frequent height adjustments. It allows for smooth raising and lowering of the desktop 40, adapting to the height and posture needs of different users. The sliding structure is easy to maintain and highly durable. A camera 30 monitors the distance between the user's legs and the desktop 40 in real time, providing feedback signals. Through image recognition technology, it intelligently determines whether the desktop 40 needs height adjustment, achieving automated adjustment without manual user operation. The intelligent height adjustment of the study desk 100 improves user experience, ensures correct posture, and reduces fatigue and health problems. The first slide rail 12 is rotatably connected to the table leg 11, and the second slide rail 13 is rotatably connected to the height adjustment section 10, with a spring 14 connecting the two. This design allows the slide rail to rotate and drive the spring 14 to contract or extend when the table leg 11 slides. The elastic force of the spring 14 provides cushioning, making the raising and lowering of the desktop 40 more smooth. The rotating design of the slide rail increases the structural flexibility, adapting to different height adjustment needs. Spring 14 is connected between the first slide rail 12 and the second slide rail 13, providing elastic support when the table leg 11 slides. The contraction or extension of spring 14 can balance the weight of the tabletop 40, reduce the load on the drive mechanism, provide a certain damping effect, and prevent the tabletop 40 from rising or falling too quickly or too slowly.

[0042] More preferably, the study desk 100 further includes a desktop 40. The desktop 40 is fixedly connected to the two support parts 20 and is located on the side of the support parts 20 opposite to the height adjustment part 10. When the legs 11 of the desktop 40 slide in the vertical direction, the support parts 20 also move in the vertical direction, and the desktop 40 also moves in the vertical direction.

[0043] The desktop 40 is fixedly connected to the support 20, which in turn is fixedly connected to the height adjustment unit 10. The height adjustment unit 10 adjusts its height by sliding the table legs 11. When the table legs 11 slide vertically, the support 20 and the desktop 40 move synchronously. This ensures that the desktop 40 remains level during height adjustment, preventing tilting or imbalance. This design improves the user experience and avoids discomfort or inconvenience caused by a tilted desktop 40. The desktop 40 and support 20 are fixedly connected, and the support 20 and height adjustment unit 10 are fixedly connected, forming a single integrated structure. The coordinated design between the table legs 11, height adjustment unit 10, support 20, and desktop 40 enhances the stability of the overall structure, preventing the desktop 40 from wobbling or shifting during height adjustment, and improving the durability and reliability of the study table 100, making it suitable for long-term use. The table legs 11, support 20, and desktop 40 move synchronously through their fixed connection. When the table leg 11 slides, the support 20 and the desktop 40 also move accordingly, ensuring consistent height adjustment and preventing structural misalignment or damage caused by asynchronous movement. The desktop 40 is fixedly connected to the support 20, and the support 20 is fixedly connected to the height adjustment unit 10, reducing the number of independently moving parts. The synchronized movement of the desktop 40 and support 20 ensures that the desktop 40 is always in the correct position when the user adjusts the height, improving ease of use. Users do not need to manually adjust the desktop 40's level and ensure that the distance between the user's legs and the desktop 40 remains within a suitable range, promoting healthy posture. The synchronized movement of the desktop 40 and support 20 can quickly adapt to the height and posture needs of different users, improving the versatility of the study desk 100. It is suitable for various scenarios such as home, school, or office, and its intelligent adjustment function automatically adapts to different users' habits.

[0044] More preferably, when viewed along the first surface S1 parallel to the tabletop 40, the table legs 11, the height adjustment part 10, the support part 20 and the tabletop 40 are arranged in sequence.

[0045] This arrangement optimizes the structural layout of the study desk 100, ensuring a rational spatial distribution of components, thereby improving stability, functionality, and aesthetics. By arranging the desk legs 11, height adjustment unit 10, support unit 20, and desktop 40 sequentially, smooth height adjustment and horizontal stability of the desktop 40 are achieved, while reducing space occupation and making the overall design more compact and harmonious, facilitating user operation and maintenance.

[0046] More preferably, the height adjustment part 10 is also integrally formed with a cavity 15. When the table leg 11 slides along the height adjustment part 10 in the vertical direction and the table leg 11 retracts, the table leg 11 slides into the cavity 15. When viewed in a direction parallel to the first surface S1, the table leg 11 partially overlaps with the height adjustment part 10.

[0047] This design aims to save space and maintain the overall aesthetics of the study desk 100 when the table legs 11 are retracted. The height adjustment section 10 integrally forms a cavity 15, allowing the table legs 11 to slide into this cavity during retraction, partially overlapping with the height adjustment section 10. This reduces the exposed length of the table legs 11, avoiding the occupation of extra space. This design not only makes the study desk 100 more compact when adjusting its height but also improves its neatness and harmony, while enhancing structural stability and practicality.

[0048] More preferably, the surface of the support portion 20 is referred to as the second surface S2. When viewed along a direction parallel to the first surface S1 and parallel to the second surface S2, the two support portions 20 are parallel to each other.

[0049] This design ensures the structural symmetry and stability of the study desk 100. By aligning the two support sections 20 parallel to each other in a direction parallel to the desktop 40 (first surface S1) and the surface of the support section 20 (second surface S2), the weight of the desktop 40 is evenly distributed, preventing tilting or imbalance caused by asymmetry of the support sections 20. This design not only enhances the overall structural stability and durability but also makes the study desk 100 more aesthetically pleasing and easier to manufacture and assemble, thus improving the user experience.

[0050] More preferably, when viewed along a direction parallel to the second surface S2, the study table 100 further includes a fixing part 50 fixedly connected between two table legs 11, and a first connector 51 is integrally formed on the fixing part 50, and a second connector 16 is integrally formed on the height adjustment part 10.

[0051] In the design of the intelligent adjustable study desk 100, a cleverly designed fixing part 50 is positioned horizontally below the desktop 40. It is securely connected between the two table legs 11, forming a solid support base. The integrated first connector 51 on the fixing part 50 works in conjunction with the carefully designed second connector 16 on the height adjustment part 10, greatly enhancing the overall structural stability of the study desk 100 and effectively preventing tipping due to lateral forces. It also significantly reduces the wobbling of the desktop 40 during use, improving user comfort. Furthermore, this design simplifies the installation process of the table legs 11 and the height adjustment part 10, ensuring precise alignment and a secure connection, while making height adjustment smoother and more stable. The connectors may employ easy-to-operate designs such as knobs or slides, providing great convenience to users. More importantly, the fixing part 50 and the connectors can be designed to be hidden or embedded to reduce the space occupied under the desktop 40 and visual interference, improving the aesthetics of the study desk 100 and avoiding the risk of collision during use. This design takes into account multiple aspects such as structural stability, ease of installation, aesthetics, and practicality, providing users with a better learning and working environment.

[0052] More preferably, the first slide groove 12 is connected to the first connecting member 51 and a first fixing pin 12A is connected between them; the second slide groove 13 is connected to the second connecting member 16 and a second fixing pin 13A is connected between them. The first slide groove 12 rotates around the first fixing pin 12A, and the second slide groove 13 rotates around the second fixing pin 13A.

[0053] Firstly, this connection method provides a stable axis of rotation. The fixing pin, serving as the center of rotation, ensures that the slide rail rotates smoothly and orderly around it during adjustment, avoiding wobbling or jamming caused by an unstable axis of rotation. This not only improves the accuracy and smoothness of adjustment but also extends the lifespan of the components. Secondly, this design simplifies the structure and enhances reliability. Connecting the slide rail and connectors with the fixing pin reduces additional connecting parts and complexity, making the entire adjustment mechanism more compact and efficient. Simultaneously, the fixing pin, as a common form of mechanical connection, has the advantages of simple structure, ease of manufacturing and maintenance, thereby improving the overall reliability and durability of the study desk 100. Furthermore, this connection method facilitates adjustment and adaptation to different usage scenarios. Because the slide rail can rotate around the fixing pin, the height and angle of the table legs 11 can be flexibly adjusted according to the user's height, sitting posture, and the needs of the desktop 40. This flexibility not only improves the adaptability and practicality of the study desk 100 but also provides users with a more comfortable and personalized user experience.

[0054] More preferably, when viewed along a direction parallel to the first surface S1, when the table leg 11 slides vertically along the height adjustment part 10 and the table leg 11 shortens, the first slide groove 12 rotates around the first direction F1, the second slide groove 13 rotates around the first direction F1, and the spring 14 contracts.

[0055] Firstly, this rotation method ensures the smoothness and consistency of the table leg 11 during the shortening process. When the table leg 11 shortens, if the first slide rail 12 and the second slide rail 13 can rotate synchronously and smoothly in the same direction, the movement trajectory of the table leg 11 will be more stable and controllable, avoiding wobbling or jamming caused by asynchronous or irregular rotation. This not only improves the precision and smoothness of adjustment but also provides users with a more comfortable experience. Secondly, the retraction design of the spring 14 plays a role in buffering and energy storage. During the shortening process of the table leg 11, the retraction of the spring 14 can absorb some of the impact force, slowing down the descent speed of the table leg 11, making the entire adjustment process smoother and gentler. At the same time, the energy storage characteristic of the spring 14 also means that when the table leg 11 needs to be extended, the spring 14 can release the stored energy to assist the upward movement of the table leg 11, thereby reducing the user's operational burden. In addition, this design also takes into account the compactness of the structure and the utilization of space. By allowing the first slide rail 12 and the second slide rail 13 to rotate around the fixed pin, and by utilizing the contraction of the spring 14 to assist in the adjustment of the table legs 11, the designer was able to achieve an efficient adjustment mechanism within a limited space. This not only reduces the overall size and weight of the study table 100, but also improves its portability and flexibility. Finally, this design also helps to improve the adaptability and durability of the study table 100. Since the height of the table legs 11 can be flexibly adjusted, the study table 100 can accommodate users of different heights and usage habits. At the same time, the contraction and release process of the spring 14 also helps to disperse and alleviate stress concentration in the table legs 11 during movement, thereby extending the overall lifespan of the study table 100.

[0056] More preferably, when viewed along a direction parallel to the first surface S1, when the table leg 11 slides vertically along the height adjustment part 10 and the table leg 11 extends, the first slide groove 12 rotates around the second direction F2, the second slide groove 13 rotates around the second direction F2, and the spring 14 is stretched.

[0057] In the ingenious design of the intelligent adjustable study desk 100, when the desk leg 11 slides vertically along the height adjustment section 10 to extend, the first slide rail 12 and the second slide rail 13 are carefully designed to rotate synchronously in the same direction (opposite to the direction of rotation when the desk leg 11 shortens), and a tensioning mechanism of the spring 14 is cleverly introduced. This design aims to ensure the smoothness and precision of the desk leg 11's extension, avoiding wobbling and jamming through the synchronous rotation of the slide rails, making height adjustment smoother. At the same time, the tension of the spring 14 not only stores energy to assist the desk leg 11 in a smooth descent when lowering, reducing the user's operational burden, but also acts as a buffer, protecting the height adjustment section 10 and the desk leg 11 from impact damage. In addition, this design greatly improves the compactness of the structure and the utilization of space, making the study desk 100 more portable and flexible while maintaining high performance. More importantly, the flexible height adjustment of the table legs 11 enhances the adaptability of the study table 100, meeting the needs of users with different heights and usage habits, while the energy storage and release characteristics of the springs 14 further extend the service life of the entire study table 100.

[0058] More preferably, when viewed along a direction parallel to the second surface S2, a first crossbeam 60 is fixedly connected between the two first slides 12, and the first crossbeam 60 is perpendicular to the two first slides 12 respectively. A second crossbeam 70 is fixedly connected between the two second slides 13, and the second crossbeam 70 is perpendicular to the two second slides 13 respectively.

[0059] Firstly, the introduction of the first crossbeam 60 and the second crossbeam 70 significantly enhances the overall structural strength of the study desk 100. As lateral supports, they effectively connect the two parallel sliding tracks, forming a more stable frame, thereby improving the stability and resistance to deformation of the study desk 100 when bearing heavy loads or subjected to external forces. Secondly, this design optimizes the force distribution of the sliding tracks. When the desk legs 11 are height adjusted, the sliding tracks are subjected to sliding friction and potential lateral forces from the height adjustment section 10. Through the fixed connection of the crossbeams, the forces on the sliding tracks can be more evenly distributed across the entire frame, reducing the load pressure on individual tracks and extending the service life of the tracks and the height adjustment section 10. Furthermore, the crossbeams also help improve the accuracy and stability of the adjustment. During the extension or retraction of the desk legs 11, the crossbeams ensure that the two sliding tracks move synchronously and smoothly, avoiding wobbling caused by asynchrony or misalignment, making height adjustment more precise and smooth. More importantly, this design also considers a balance between aesthetics and practicality. The clean, flowing lines of the crossbeam create a harmonious visual effect with the sliding groove and height adjustment section 10, enhancing the overall aesthetics of the study desk 100. At the same time, the sturdy structure of the crossbeam provides users with additional storage space or the option to use it as an armrest, increasing the practicality of the study desk 100.

[0060] By using the camera 30 to capture an image below the horizontal plane, the height adjustment unit 10 can be adjusted so that the distance between the desktop 40 and the student's thighs can be obtained. The study table 100 can effectively adjust the height of the desktop 40 according to the distance. When the height adjustment unit 10 automatically slides the table legs 11 according to the image, the spring 14 contracts or extends, and the first slide groove 12 and the second slide groove 13 rotate around the height adjustment unit 10, which improves the convenience of adjustment.

[0061] The embodiments described above are merely examples of several implementation methods of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these modifications and improvements all fall within the protection scope of this application.
