[0028] Please see Figures 1 to 3 An electrically adjustable keyboard tray 3 is disclosed in this paper. The desk includes a desk body, a keyboard tray 3, and an electrically adjustable mechanism 4. The desk body includes a tabletop 1 and table legs 2 for supporting the tabletop 1. The electrically adjustable mechanism 4 is installed below the tabletop 1, and the keyboard tray 3 is mounted on the electrically adjustable mechanism 4. The electrically adjustable mechanism 4 is used to adjust the tilt angle of the keyboard tray 3 relative to the horizontal plane. The user can adjust the keyboard tray 3 to tilt downwards or upwards relative to the horizontal plane by controlling the electrically adjustable mechanism 4 to meet different usage needs. The user can operate the electrically adjustable mechanism 4 through a control panel located on the keyboard tray 3. To prevent the keyboard tray 3 from colliding with the tabletop 1 when tilted upwards and to prevent items such as keyboards from falling off the keyboard tray 3 when tilted downwards, the tilt angle adjustment range of the keyboard tray 3 is limited to ±15 degrees. It should be noted that "keyboard tray 3" is a general term for office furniture and is not limited to holding only keyboards. In practical applications, the keyboard tray 3 can be used to hold other items such as keyboards, mice, laptops, documents, etc., depending on the actual usage needs.

[0029] By setting up an electric adjustment mechanism 4, the keyboard tray 3 can be electrically adjusted. Users can easily adjust the tilt angle of the keyboard tray 3 according to different scenarios such as typing and watching movies, as well as different sitting postures, to find the most comfortable wrist posture and effectively relieve wrist fatigue caused by long hours of office work.

[0030] Please see Figure 2 , Figure 4 and Figure 5 The desk includes a sliding mechanism 5, which is installed on the lower end of the desk panel 1. An electric adjustment mechanism 4 is installed on the sliding mechanism 5, allowing the electric adjustment mechanism 4 and the keyboard tray 3 to move relative to the desk panel 1 between a storage position and a use position; that is, the keyboard tray 3 can be stored under the desk panel 1 or pulled out to the front of the desk panel 1. Figure 1 The diagram shows the keyboard tray 3 pulled out to the front of the desktop 1 and tilted downwards. Figure 3The diagram shows the keyboard tray 3 stowed under the tabletop 1 with the keyboard tray 3 remaining horizontal. The sliding mechanism 5 allows the keyboard tray 3 to be easily pushed and pulled under the tabletop 1 without taking up extra space.

[0031] Please see Figure 6 The sliding mechanism 5 includes a slide rail 51 and a slider 52. The slide rail 51 is installed on the lower end surface of the tabletop 1, and its length direction is consistent with the front-to-back direction of the tabletop 1. The slider 52 is slidably installed on the slide rail 51, and the electric adjustment mechanism 4 is connected to the slider 52. When the slider 52 slides on the slide rail 51, it drives the electric adjustment mechanism 4 and the keyboard tray 3 to move synchronously. The user can achieve this movement by manually pushing and pulling. That is, the user can push and pull the keyboard tray 3 to store it under the tabletop 1 or pull it out for convenient use. The sliding mechanism 5 has a simple structure, the keyboard tray 3 is easy to push and pull, and the operation is simple.

[0032] Please see Figure 6 The sliding mechanism 5 includes two slide rails 51, two sliders 52, and two connecting rods 53. The two slide rails 51 are fixedly mounted on the lower end surface of the tabletop 1, facing each other and parallel to each other. The two connecting rods 53 are respectively connected to the two ends of the two slide rails 51, so that the two slide rails 51 and the two connecting rods 53 are connected end-to-end to form a stable rectangular frame structure. One slider 52 is slidably mounted on each slide rail 51. The two ends of the electric adjustment mechanism 4 are respectively connected to two of the sliders 52.

[0033] Please see Figures 6 to 7 The electric adjustment mechanism 4 includes an adjustment drive device 41, an angle adjustment assembly 42, a mounting plate 43, a rotating frame 44, and a protective cover 45.

[0034] Mounting plate 43 is a flat plate structure, with two opposing angle adjustment components 42 mounted on its lower end surface. Both ends of mounting plate 43 are fixedly connected to two sliders 52, respectively. For details, please refer to [link to relevant documentation]. Figure 8 A recessed slot 521 is provided on the side of the slider 52, and the two ends of the mounting plate 43 are respectively inserted into the slots 521 of the two sliders 52. This arrangement can improve the structural stability and can use the slide rail 51 to restrict the position of the slider 52, thereby restricting the position of the slider 52 on the mounting plate 43 and ensuring the stability of the structure.

[0035] Please see Figure 9The tilt adjustment assembly 42 includes a base plate 421 and a gear plate 422. The upper end of the base plate 421 is fixedly mounted on the mounting plate 43 and located below the mounting plate 43. The fixed part of the gear plate 422 is connected to the base plate 421 for mounting on the base plate 421. The rotating part of the gear plate 422 is connected to the output shaft of the adjustment drive device 41 and also to the keyboard tray 3. Rotation of the output shaft of the adjustment drive device 41 can drive the rotating part of the gear plate 422 to rotate, thereby driving the keyboard tray 3 to rotate to adjust the tilt angle of the keyboard tray 3. The tilt adjustment assembly 42 is similar to the core component of a tilt adjuster, which is a common angle adjustment device and will not be described in detail here.

[0036] In this embodiment, a motor is used as the drive source, and the output shaft of the adjustment drive device 41 is connected to the gear plate 422 of one of the angle adjustment components 42. The two angle adjustment components 42 are arranged symmetrically, and the two gear plates 422 are respectively connected to the two sides of the rotating frame 44. The keyboard tray 3 is fixedly mounted on the rotating frame 44, that is, the rotating part of the gear plate 422 is connected to the keyboard tray 3 through the rotating frame 44. When the adjustment drive device 41 drives the rotating part of one of the gear plates 422 to rotate, the rotating frame 44 rotates accordingly, and the rotation of the rotating frame 44 will cause the rotating part of the other gear plate 422 to rotate, thus achieving smooth rotation of the rotating frame 44. In this way, the rotation of the output shaft of the adjustment drive device 41 can be transmitted to the keyboard tray 3 through the gear plate 422 and the rotating frame 44, driving the keyboard tray 3 to tilt upward (positive angle) or downward (negative angle) relative to the horizontal plane. By using the symmetrical arrangement of the two angle adjustment components 42, and cooperating with the rotating frame 44 to transmit torque, it is ensured that the keyboard tray 3 is subjected to uniform force and runs smoothly during the adjustment process.

[0037] Please see Figure 6 and Figure 11 The protective cover 45 is a cover structure installed on the lower end face of the mounting plate 43, covering the outside of the adjustment drive device 41 and the two angle adjustment components 42, serving as a dustproof and protective function. The protective cover 45 has a clearance opening 451 for the rotating bracket 44 to extend and rotate freely, ensuring that it does not interfere with the tilt angle adjustment of the keyboard tray 3. The design of the protective cover 45 not only protects the internal transmission mechanism and prevents dust intrusion, but also enhances the overall aesthetics.

[0038] To prevent damage to the mechanism due to excessive rotation of the keyboard tray 3, this embodiment also includes a limiting structure. Please refer to [link / reference]. Figure 7 , Figure 9 Each angle adjustment component 42 has a raised limiting block 423 on its base plate 421. Also, please refer to... Figure 10An arc-shaped limiting notch 441 is provided at the corresponding position of the rotating frame 44. When the rotating frame 44 rotates with the output end of the angle adjustment component 42, the limiting block 423 is located within the limiting notch 441. When the rotating frame 44 rotates to its limit position, the side of the limiting block 423 abuts against the side of the limiting notch 441, thereby preventing the rotating frame 44 from continuing to rotate. By designing the arc of the limiting notch 441, the rotation stroke of the keyboard tray 3 can be precisely controlled. Preferably, the tilt angle adjustment range of the keyboard tray 3 is limited to within ±15 degrees. The cooperative design of the limiting block 423 and the limiting notch 441 can precisely control the rotation stroke and prevent damage to the mechanism caused by over-adjustment.

[0039] In this embodiment, there are two table legs 2, both of which are height-adjustable. The two table legs 2 are arranged parallel to each other on both sides below the tabletop 1. Please refer to [link / reference]. Figure 12 The table legs 2 are equipped with a lifting drive device 6, which is used to drive the table legs 2 to extend and retract, thereby realizing the raising and lowering of the tabletop 1. The lifting drive device 6 can be implemented using a drive motor combined with a lead screw or push rod, which are common in the art, and will not be described in detail here. The desk in this embodiment is a height-adjustable desk, and the tabletop 1 can be raised and lowered. The raising and lowering of the tabletop 1 can drive the keyboard tray 3 to rise and fall synchronously.

[0040] In other embodiments, the desk also includes a control system (not shown), which is electrically connected to the lifting drive 6 and the adjustment drive 41 of the electric adjustment mechanism 4, respectively. The control system is configured to execute a linkage control mode.

[0041] When the user tilts the keyboard tray 3 downwards (i.e., tilts in the first direction, such as a negative angle) via the control panel (not shown in the figure), the control system simultaneously sends commands to the adjustment drive device 41 and the lifting drive device 6. The adjustment drive device 41 drives the keyboard tray 3 to tilt downwards to the target angle, while the lifting drive device 6 drives the tabletop 1 to rise to a preset height. In this way, when the user leans forward slightly and their wrists naturally press down, the keyboard tray 3 adjusts accordingly, and the rise of the tabletop 1 ensures that the distance and angle between the screen and the user's eyes remain comfortable. Conversely, when the user tilts the keyboard tray 3 upwards (i.e., tilts in the second direction, such as a positive angle), the control system simultaneously controls the lifting drive device 6 to lower the tabletop 1.

[0042] To achieve precise coordination, the control system has preset linkage parameters that ensure a positive correlation between the change in the tilt angle of the keyboard tray 3 and the change in the height of the tabletop 1. For example, it can be set so that for every 2 degrees the keyboard tray 3 tilts downwards, the tabletop 1 rises by 2 centimeters simultaneously. This linkage parameter can be customized by the user through the controller according to their personal preferences.

[0043] By controlling the system to preset the linkage ratio, when the keyboard tray 3 tilts downward, the tabletop 1 automatically rises, and when the keyboard tray 3 tilts upward, the tabletop 1 automatically lowers, so that users can maintain a comfortable position of their hands and keyboard, and their line of sight and screen in different sitting postures, which greatly improves the user experience.

[0044] Please see Figures 1 to 3 The desk in this embodiment also includes a first footrest 7 and a second footrest 8. Both are horizontally fixed between the two desk legs 2, with the first footrest 7 located below the second footrest 8, creating footrest positions at different heights. When the user is sitting upright, their feet can naturally rest on the lower first footrest 7; when the user is leaning back or reclining on the chair back, their feet can be raised to rest on the upper second footrest 8, further enhancing comfort during rest. The different heights of the footrests can meet the user's footrest needs when sitting upright or leaning back, further relieving leg fatigue.

[0045] Please see Figures 1 to 3 On the outer sides of the two table legs 2, storage boxes 9 are detachably installed. These storage boxes 9 can be used to store items such as power strips, chargers, and various connecting cables, keeping the space under the table neat and tidy. The detachable storage boxes 9 make it easy to organize power cords, chargers, and other miscellaneous items, keeping the desktop and the space under the table clean and tidy.

[0046] In summary, the electrically adjustable keyboard tray 3 desk provided by this invention achieves electric adjustment of the keyboard tray 3 angle through the electric adjustment mechanism 4, realizes the storage and extension of the keyboard tray 3 through the sliding mechanism 5, realizes intelligent linkage between the tilt angle of the keyboard tray 3 and the height of the tabletop 1 through the control system, and is further enhanced by humanized designs such as the first foot pedal 7, the second foot pedal 8 and the storage box 9, greatly improving the user's comfort and convenience; the entire desk conforms to ergonomic design from multiple angles.

[0047] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
