Description

Technical Field

[0001] This utility model relates to a cantilevered study desk with synergistic lighting. Background Technology

[0002] With the advent of the information age, modern people's learning and working methods have undergone profound changes, often requiring the simultaneous use of electronic devices (such as tablets and e-readers) and traditional paper books and documents. To meet the needs of this blended learning and working environment, users typically configure separate device stands and desk lamps on their desktops.

[0003] However, existing technical solutions have the following obvious shortcomings:

[0004] 1. Scattered equipment and cluttered desktop space: In current technology, desk lamps and equipment stands are two separate entities, each with its own base, requiring separate placement on the desktop. This not only occupies a significant amount of usable workspace, making the desktop appear crowded and cluttered, but also makes adjusting their positions relatively cumbersome, impacting work and study efficiency.

[0005] 2. Lighting conflicts with device placement, resulting in unsatisfactory illumination: Traditional desk lamps have relatively fixed light source positions or limited adjustment ranges. When the user places the device stand in the optimal viewing position, the device itself or the user's body or hands can easily block the lamp's light, creating shadows in the writing or reading area below, severely impacting visual comfort and learning efficiency. Conversely, moving the lamp to avoid shadows may cause glare or reflections on the device screen, similarly interfering with vision. Current technology lacks a solution that can coordinate with device placement to provide unobstructed lighting.

[0006] 3. Limited adjustability and poor human-computer interaction: While most device stands and desk lamps on the market offer some adjustment capabilities, these are typically limited in scope and adjustment. Users often struggle to simultaneously adjust the viewing angle, height, and light source angle and position of electronic devices to their optimal ergonomic state. This "accommodating" approach can, over time, lead to poor posture, causing neck pain, vision problems, and other health issues.

[0007] 4. Disorganized cable management poses safety hazards: Desk lamps require power cords, and electronic devices also need charging cables for extended use. In existing desktop setups, these cables inevitably become tangled and intertwined, severely impacting the cleanliness and aesthetics of the desktop. They are also prone to being accidentally pulled when moving items or adjusting devices, potentially causing equipment to fall and be damaged, or even posing tripping or electrical hazard.

[0008] In summary, designing a study desk that combines device support with high-quality lighting, achieves highly flexible adjustment and neat wiring, thereby optimizing the hybrid learning and working experience, is a technical problem that urgently needs to be solved in this field. The technical background section of this utility model aims to describe the current state of the existing technical field. The shortcomings of the prior art are indicated in this section. This section will provide necessary background information for understanding the technical contributions and innovations of this utility model. The signals disclosed in this background section are only intended to enhance the understanding of the overall background of this utility model and should not be regarded as implying any subjective intent in any way. Utility Model Content

[0009] In view of the above, the purpose of this utility model is to provide a cantilevered study desk with synergistic lighting.

[0010] The technical solution adopted to achieve the purpose of this utility model is a cantilevered study desk with coordinated lighting, including a tabletop and table legs for supporting the tabletop. The study desk also includes a multi-functional support device, which is fixedly installed in the rear edge area of ​​the tabletop. The multi-functional support device includes:

[0011] The fixed base has a mounting surface at its bottom that is adapted to the surface of the tabletop. The mounting surface is used to securely install the fixed base onto the tabletop. The top of the fixed base has an integrally extended vertical rotation shaft that serves as the driving component of the first rotational joint.

[0012] The support arm has a bushing structure at its lower end that is adapted to the vertical rotation axis. The bushing structure is rotatably fitted onto the vertical rotation axis as a driven member of the first rotation pair, forming a planar rotation pair that allows the support arm to rotate horizontally around the center line of the vertical rotation axis.

[0013] An adjusting arm, the proximal end of which is pivotally connected to the distal end of a support arm via a second rotating joint. The second rotating joint includes a pin horizontally disposed at the distal end of the support arm and a connecting lug disposed at the proximal end of the adjusting arm, having a through hole parallel to the axis of the pin. The connecting lug is rotatably inserted through its through hole onto the pin, thereby forming a rotating pair that allows the adjusting arm to pitch and swing about the center line of the pin.

[0014] The equipment clamping device is connected to the distal end of the adjusting arm via a third rotary joint. The third rotary joint is a spherical universal joint structure, which includes a ball head integrally extending from the distal end of the adjusting arm and a ball socket fixed to the back of the equipment clamping device, the inner cavity of which matches the surface of the ball head. The ball socket rotatably covers the ball head to allow the equipment clamping device to perform multi-degree-of-freedom spatial attitude adjustment relative to the adjusting arm.

[0015] The lighting module is a long strip-shaped light source. The adjustment arm has a mounting groove along its length on the lower surface of the table. The lighting module is embedded and fixed in the mounting groove, so that the light-emitting surface of the lighting module and the lower surface of the adjustment arm form a continuous and flush plane.

[0016] Furthermore, the support arm is a multi-section telescopic structure, which includes a base connecting tube connected to the bushing structure, and at least one telescopic tube that can be axially slidably engaged in the inner cavity of the base connecting tube; a locking mechanism is provided between the base connecting tube and the telescopic tube to lock them axially, so as to realize stepless or stepped adjustment of the overall length of the support arm.

[0017] Furthermore, the locking mechanism is a locking collar disposed at the port of the base connecting pipe and surrounding the telescopic pipe. The inner wall of the locking collar is provided with threads, and the outer wall of the port of the base connecting pipe is provided with external threads that cooperate with the locking collar. By screwing the locking collar, the axial pressure of the threaded engagement forces the port of the base connecting pipe to contract radially, thereby clamping the telescopic pipe.

[0018] Furthermore, the second rotating joint is also provided with an angle locking device for fixing the pitch angle of the adjusting arm. The angle locking device includes a locking bolt that passes through the connecting lug and the pin, and a handle knob that is threadedly engaged with the locking bolt. By tightening the handle knob, the friction between the connecting lug and the distal end face of the support arm can be increased, thereby locking the adjusting arm in a preset pitch position.

[0019] Furthermore, the device clamping device includes: a rigid back plate as the main body, wherein the ball socket of the spherical universal joint structure is fixed to the back of the rigid back plate; at least two clamping arms symmetrically and movably connected to opposite sides of the rigid back plate; and a spring return mechanism built into the rigid back plate, wherein the spring return mechanism is linked with the at least two clamping arms and continuously applies a clamping force to the clamping arms to bring them closer together.

[0020] Furthermore, inside the structure of the fixed base, support arm, and adjusting arm, a cable receiving channel is provided that runs through the central axis of each component; the vertical rotation shaft and the pin are both designed as hollow tubular structures to serve as transition paths for the cable receiving channel at the first and second rotation joints, thereby forming an internal wiring space extending from the bottom of the fixed base to the far end of the adjusting arm.

[0021] Furthermore, a power interface is provided on the side wall of the fixed base, and the starting end of the cable receiving channel is connected to the internal electrical connection terminal of the power interface; the end of the cable receiving channel at the distal end of the adjusting arm branches into a first electrical branch and a second electrical branch, the first electrical branch being electrically connected to the power supply terminal of the lighting module, and the second electrical branch being connected to a charging device provided on the equipment clamping device.

[0022] The beneficial effects of this utility model are:

[0023] 1. High space utilization: This utility model organically integrates three major functions—equipment support, multi-angle adjustment, and local lighting—into a single, multi-functional support device. Fixed to the rear edge of the tabletop, its cantilever structure lifts the equipment and light source off the table, greatly freeing up valuable work surface space and solving the problem of clutter and cramped space caused by placing various items such as independent lamps and equipment supports on traditional desktops.

[0024] 2. Synergistic Lighting for Excellent Illumination: This innovative design embeds a long, strip-shaped lighting module under the adjusting arm, making its luminous surface flush with the arm's surface. This design allows the light source to precisely and evenly illuminate the desktop area directly below the device, perfectly solving the lighting needs of users reading physical books or writing notes while using electronic devices. It fundamentally eliminates the device or hand shadows caused by the side illumination of traditional desk lamps, while also avoiding the interference of electronic device screen reflections on physical book reading, providing a glare-free and unobstructed high-quality local lighting environment.

[0025] 3. Multi-dimensional adjustment and superior ergonomic performance: By setting up a three-stage rotary joint consisting of a planar rotary joint, a pitch rotary joint, and a spherical universal joint, combined with a retractable support arm design, this invention achieves all-round, multi-degree-of-freedom adjustment of the equipment and light source in horizontal, vertical, near and far, and spatial posture. Users can easily adjust the electronic equipment and lighting source to any most comfortable and healthy ergonomic position according to their height, sitting posture, and usage scenario, effectively preventing cervical fatigue and vision damage caused by poor posture or unfavorable viewing angles.

[0026] 4. Integrated Structure, Neat, Beautiful, and Safe: This invention cleverly incorporates through-channels for cables within each component of the device and designs the pivot of the rotating joint as a hollow structure, achieving complete internal integration of the power cord and charging cable. This design not only fundamentally solves the problem of tangled and messy wires from multiple devices in traditional solutions, making the entire study desktop environment extremely neat and beautiful, but also avoids the safety hazards of wear and tear caused by exposed cables, improving the product's durability and safety. Simultaneously, the integrated charging interface provides a convenient "use while charging" solution for electronic devices, further enhancing the user experience. Attached Figure Description

[0031] The present invention will now be described in this embodiment with reference to the accompanying drawings and some embodiments.

[0032] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0033] The following description, in conjunction with the accompanying drawings and embodiments, further illustrates the cantilevered study desk with collaborative lighting according to this utility model, aiming to help understand the technical concept and specific implementation of this utility model. However, this description should not be construed as limiting the scope of protection of this utility model.

[0034] See Figure 1-2As shown, the basic structure of this study desk includes a tabletop for studying and working, and at least two legs for stable support of the tabletop. The core innovation of this invention lies in the integration of a multi-functional support device.

[0035] This multi-functional support device is designed to be fixedly installed on the rear edge of the tabletop, ensuring its stability without excessively encroaching on the user's main workspace. Specifically, the multi-functional support device includes the following components:

[0036] Fixed base: This is the foundation for the connection between the entire multi-functional support device and the tabletop. Its bottom is designed with a mounting surface that conforms to the contours of the tabletop, allowing for secure installation using screws, strong adhesives, or clamps. To enable rotation of subsequent components, a vertical rotation shaft extends integrally upwards from the top of the fixed base. This vertical rotation shaft serves as the driving component of the first rotating pair in a key rotational structure of this invention.

[0037] Support Arm: The support arm is the main load-bearing structure that enables the cantilever function. Its lower end (or proximal end) is equipped with a bushing structure that precisely matches the dimensions and shape of the aforementioned vertical rotation axis. This bushing structure, acting as the driven component of the first revolute joint, is rotatably fitted onto the vertical rotation axis. This fit constitutes a planar revolute joint, allowing the support arm to rotate 360 ​​degrees horizontally about the centerline of the vertical rotation axis. The user can therefore easily swing the entire support arm, along with the equipment above it, left and right to adjust its horizontal position.

[0038] Adjustable Arm: The adjustable arm is connected to the distal end of the support arm and is used to adjust the pitch direction. The proximal end of the adjustable arm is pivotally connected to the distal end of the support arm via a second rotary joint. The specific structure of this second rotary joint is as follows: a pin is horizontally positioned at the distal end of the support arm; simultaneously, a connecting lug with a through hole is provided at the proximal end of the adjustable arm. The axis of the through hole is parallel to the axis of the pin. By rotatably inserting the through hole of the connecting lug onto the pin, a rotary joint is formed that allows the adjustable arm to pitch up and down around the center line of the pin. This design allows the user to adjust the height and vertical angle of the equipment and the light source.

[0039] Device clamping device: To facilitate users placing learning devices such as e-readers, tablets, or mobile phones, a device clamping device is connected to the distal end of the adjusting arm via a third rotary joint. For maximum flexibility, this third rotary joint is preferably a spherical universal joint structure. Specifically, a ball head extends integrally from the distal end of the adjusting arm, while a ball socket is fixedly connected to the back of the device clamping device. The inner curved surface of the ball socket matches the surface of the ball head. The ball socket rotatably covers the ball head, allowing the device clamping device to perform multi-degree-of-freedom spatial posture adjustments relative to the adjusting arm, including but not limited to left and right swaying, up and down nodding, and rotation around its own center, greatly facilitating users to view the device screen from any comfortable angle.

[0040] Lighting Module: Another major innovation of this invention lies in the synergistic integration of lighting and equipment support functions. The lighting module is specifically a long, strip-shaped light-emitting element, such as an LED light strip. To achieve an aesthetically pleasing and seamless integration, a mounting groove is formed along the length of the lower surface of the adjusting arm facing the tabletop. The lighting module is precisely fitted and fixed within this mounting groove. This design allows the light-emitting surface of the lighting module to form a continuous and flush plane with the lower surface of the adjusting arm. Not only is the structure compact, but more importantly, it provides direct, uniform, and shadow-free lighting to the tabletop surface below the equipment clamping device, perfectly solving the problems of obstruction and glare that may occur with traditional desk lamps or screen light when reading physical books or taking notes.

[0041] In a preferred embodiment, the support arm is designed as a multi-section telescopic structure. Specifically, it includes a base connecting tube (outer tube) connected to a bushing structure, and at least one telescopic tube (inner tube) that can slide axially within the cavity of the base connecting tube. A locking mechanism is also provided between the base connecting tube and the telescopic tube to lock their relative axial positions. This locking mechanism allows the user to easily adjust and fix the overall length of the support arm, thereby achieving stepless or stepped adjustment of the cantilever extension distance to accommodate users of different body types and different usage scenarios.

[0042] More specifically, as a feasible implementation of the aforementioned locking mechanism, the locking mechanism can be designed as a locking collar located at the port of the base connecting pipe and surrounding the telescopic tube. The inner wall of the locking collar is threaded, while the outer wall of the port of the base connecting pipe is machined with external threads that mate with the locking collar. When the user needs to lock, simply tighten the locking collar; the axial pressure generated by the threaded engagement forces the slit port of the base connecting pipe to radially contract, thereby clamping the inner telescopic tube from the outside in, achieving a reliable lock. Tightening in the opposite direction releases the lock and allows for length adjustment.

[0043] To prevent unexpected pitch angle changes due to gravity when the adjusting arm is carrying heavy equipment, an angle locking device is added at the second rotating joint. One specific structure of this angle locking device includes a locking bolt passing through the connecting lug and the pin, and a handle knob that is threaded into the locking bolt. After the adjusting arm is adjusted to the ideal pitch angle, the user can tighten the handle knob to increase the contact pressure between the side of the connecting lug and the distal end face of the support arm, thereby using friction to firmly lock the adjusting arm in the currently preset pitch position.

[0044] The device clamping device includes: a rigid back plate as the main body, with the ball joint socket fixedly connected to the back of the back plate; at least two clamping arms, which are symmetrically and movably connected to opposite sides of the rigid back plate. To achieve automatic clamping, a spring return mechanism is also provided inside the rigid back plate. This spring return mechanism is linked to the at least two clamping arms and continuously applies a clamping force to bring the arms closer together. When the user opens the clamping arms with the device and inserts the device, the spring's restoring force automatically clamps the device, providing convenient operation and stable clamping.

[0045] To achieve power supply while maintaining a clean appearance, a cable-receiving channel was specially designed inside the structure of the fixed base, support arm, and adjusting arm, running along the central axis of each component. To ensure the wires can pass smoothly through the rotating joints without tangling or wear, the vertical rotating shaft, the core of the first rotating joint, and the pin, the core of the second rotating joint, were cleverly designed as hollow tubular structures. These hollow shafts form the transition path of the cable-receiving channel at the first and second rotating joints, thus creating a complete and concealed internal wiring space extending from the bottom of the fixed base to the far end of the adjusting arm.

[0046] Based on the aforementioned internal wiring space, the functionality of this invention can be further expanded. A power interface (such as a USB-C or DC interface) can be provided on the side wall of the fixed base for connecting an external power adapter. The starting end of the cable receiving channel is connected to the internal electrical connection terminal of this power interface. At the distal end of the adjusting arm, the end of the cable receiving channel can branch into a first electrical branch and a second electrical branch. The first electrical branch is directly electrically connected to the power supply terminal of the lighting module to power the lighting function. The second electrical branch can be connected to a charging output interface (such as a USB-A or wireless charging coil) located on the device clamping device (e.g., on the side or lower edge), thereby charging the device while clamping it, achieving a high degree of integration of support, lighting, and charging.

[0047] In summary, the cantilevered study desk with collaborative lighting disclosed in this utility model integrates a multi-degree-of-freedom cantilever bracket, equipment clamping device, and embedded lighting module into a single design, supplemented by optimized solutions such as telescopic adjustment, angle locking, and internal wiring. This not only greatly expands the functionality of traditional study desks but also provides users with a highly flexible, convenient, comfortable, and aesthetically pleasing user experience, demonstrating significant practical value and innovation.
