[0002] With the widespread adoption of desktop office scenarios, the height of the monitor, as a core device for both work and entertainment, directly affects the user's cervical spine health and office comfort. Therefore, monitor height adjustment stands have become an essential accessory for desktop offices. Among them, electric lifting stands have gradually become the mainstream products in the market due to their convenient operation and precise adjustment; at the same time, with the popularization of collaborative office work using multiple devices such as laptops, mobile phones, and tablets, users' demand for desktop expansion interfaces, wireless charging and other functions is increasing day by day. Most monitor stand products on the market currently focus on a single height adjustment function, resulting in low functional integration. Furthermore, the electric height adjustment structure has many inherent defects, failing to simultaneously meet users' multiple needs for height adjustment stability, functional integration, and ease of use. Therefore, developing a monitor stand that combines high-stability height adjustment with multi-functional integration has significant market value and practical significance.

[0014] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0015] Please see Figures 1-5A desktop riser with electric lifting function includes a main unit cover 1, a left base 16 and a right base 6. The main unit cover 1 is supported above the left base 16 and the right base 6. It also includes a lifting drive mechanism, an operation component, an expansion interface component 4 and a wireless charging component 15. The operation component and the expansion interface component 4 are both installed at the same end of the main unit cover 1, and the wireless charging component 15 is embedded in the top surface of the main unit cover 1. The lifting drive mechanism is housed inside the main unit cover 1. The lifting drive mechanism includes a motor 7, a motor transmission gear 8, a transmission shaft spur gear 9, a transmission shaft 12, a left transmission shaft bevel gear 14, a right transmission shaft bevel gear 10, a left screw bevel gear 13, and a right screw bevel gear 11. The output shaft of motor 7 is fixedly connected to motor drive gear 8. The outer surface of motor drive gear 8 meshes with the outer surface of drive shaft spur gear 9. Drive shaft spur gear 9 is coaxially and fixedly connected to drive shaft 12. One end of the drive shaft 12 is coaxially and fixedly connected to the bevel gear 14 of the left drive shaft, and the other end of the drive shaft 12 is coaxially and fixedly connected to the bevel gear 10 of the right drive shaft. The outer surface of the left drive shaft bevel gear 14 meshes with the outer surface of the left screw bevel gear 13, and the left screw bevel gear 13 is connected to the left base 16 through a ball nut pair; The outer surface of the right drive shaft bevel gear 10 meshes with the outer surface of the right screw bevel gear 11, and the right screw bevel gear 11 is connected to the right base 6 through a ball nut pair; The operating components include an up button 3 and a down button 2, both of which are electrically connected to the motor 7.

[0016] With the above technical solution, when upward movement is required, the user lightly touches the upward button 3, and the motor 7 receives the signal and starts in the forward direction. The output shaft of the motor 7 drives the motor transmission gear 8 to rotate synchronously. The motor transmission gear 8 drives the transmission shaft spur gear 9 to rotate through external surface meshing, thereby driving the transmission shaft 12 to rotate coaxially. At the same time as the transmission shaft 12 rotates, it drives the left transmission shaft bevel gear 14 and the right transmission shaft bevel gear 10 at both ends to rotate synchronously. The left transmission shaft bevel gear 14 drives the left screw bevel gear 13 to rotate through external surface meshing, and the right transmission shaft bevel gear 10 drives the right screw bevel gear 11 to rotate synchronously through external surface meshing. The left screw bevel gear 13 and the right screw bevel gear 11 rotate. During operation, the rotational motion is converted into linear lifting motion through the ball bearing nut pair, causing the left base 16 and right base 6 to extend downwards synchronously, thus raising the main unit cover 1. When the operating power of the motor 7 reaches the preset threshold, the motor 7 stops running, completing the upward limit. During descent, the user lightly touches the descent button 2, and the motor 7 receives the signal and starts in reverse. Through the same set of gear transmission chains, it drives the left screw bevel gear 13 and right screw bevel gear 11 to rotate in reverse. Through the ball bearing nut pair, it drives the left base 16 and right base 6 to retract upwards synchronously, thus lowering the main unit cover 1. When the operating power of the motor 7 reaches the preset threshold, the motor 7 stops running, completing the descent limit. When the wireless charging component is needed, the device is locked in the hidden state: the user presses the wireless charging cover 1501, the spring 1503 is compressed, and the hook structure at the bottom of the wireless charging cover 1501 and the self-locking switch 1506 interlock and lock. At this time, the top surface of the wireless charging cover 1501 is flush with the top surface of the main unit cover 1, realizing the hidden storage of the wireless charging component. The device is unlocked and popped up: the user presses the wireless charging cover 1501 again, the spring 1503 rebounds, the hook structure of the wireless charging cover 1501 and the self-locking switch 1506 are unlocked and released, and the wireless charging cover 1501 pops up along the height limiting box 1502 to the preset height, forming a raised charging station, thus completing the unlocking and popping up.

[0017] Specifically, the wireless charging component 15 includes a wireless charging faceplate 1501, a height limiting box 1502, a spring 1503, a toothed limiting box 1504, a bottom cover fixing member 1505, and a self-locking switch 1506; the bottom cover fixing member 1505 is fixedly connected to the main unit faceplate 1, the toothed limiting box 1504 is fixed above the bottom cover fixing member 1505, and the self-locking switch 1506 is installed at the center of the toothed limiting box 1504; the spring 1503 is sleeved on the outside of the self-locking switch 1506. The bottom end of the spring 1503 abuts against the toothed limiting box 1504, and the top end of the spring 1503 abuts against the wireless charging face cover 1501; the height limiting box 1502 is sleeved on the outside of the spring 1503, and the height limiting box 1502 is located between the wireless charging face cover 1501 and the toothed limiting box 1504; the bottom of the wireless charging face cover 1501 is provided with a hook structure that cooperates with the self-locking switch 1506, and the outer side wall of the wireless charging face cover 1501 slides against the inner side wall of the height limiting box 1502.

[0018] Through the above technical solution, the wireless charging cover 1501, height limiting box 1502, spring 1503, toothed limiting box 1504, bottom cover fixing component 1505, and self-locking switch 1506 simultaneously define the connection and cooperation relationship of each component. Through a purely mechanical pressing self-locking structure, the wireless charging cover 1501 can switch between flush hiding and raised operation, without the need for additional electronic control components, making the structure simple and reliable. It not only ensures the overall appearance of the main unit cover 1 and avoids dust accumulation and bumps on the raised part, but also improves the fit between the phone and the charging coil through the pop-up raised structure, reducing the difficulty of alignment and preventing the phone from slipping during charging. At the same time, the layered component layout facilitates assembly and later maintenance, effectively improving the practicality and service life of the wireless charging function.

[0019] Specifically, a protective box 17 is fixed inside the main unit cover 1. Both ends of the drive shaft 12 are rotatably connected to the main unit cover 1 through the protective box 17. The left drive shaft bevel gear 14 and the right drive shaft bevel gear 10 are both housed in the protective box 17 on the corresponding side.

[0020] Through the above technical solution, the protective box 17 can radially limit the two ends of the transmission shaft 12 to prevent radial runout during the rotation of the transmission shaft 12, ensure the accuracy of the meshing of the bevel gears on the left and right sides, and at the same time form a closed protection for the bevel gear 14 of the left transmission shaft and the bevel gear 10 of the right transmission shaft to prevent dust and debris from entering the gear meshing surface and causing wear and jamming, effectively improving the operational stability and overall service life of the lifting transmission structure.

[0021] Specifically, the left screw bevel gear 13 includes a coaxially integrally formed bevel gear segment and a screw segment. The outer surface of the bevel gear segment meshes with the outer surface of the left drive shaft bevel gear 14. The screw segment is connected to the inside of the left base 16 through a ball nut pair. A base bevel gear connecting screw 5 is provided between the left screw bevel gear 13 and the left base 16. The right screw bevel gear 11 includes a coaxially integrally formed bevel gear segment and a screw segment. The outer surface of the bevel gear segment meshes with the outer surface of the right drive shaft bevel gear 10. The screw segment is connected to the inside of the right base 6 through a ball nut pair. A base bevel gear connecting screw 5 is provided between the right screw bevel gear 11 and the right base 6.

[0022] The above technical solution integrates bevel gear transmission and screw lifting function into one unit, which greatly shortens the transmission chain and improves transmission efficiency. At the same time, the base bevel gear connecting screw 5 limits and fixes the screw bevel gear to the corresponding base, avoiding loosening or offset during lifting, ensuring complete consistency of the lifting stroke on the left and right sides, and further improving the stability of the bracket lifting and the reliability of the structural connection.

[0023] Specifically, the up button 3 and the down button 2 are arranged side by side along the width of the main unit cover 1, and the expansion interface component 4 is located next to the operation component. Multiple interfaces of the expansion interface component 4 are exposed on the end side wall of the main unit cover 1.

[0024] Through the above technical solution, the up button 3 and down button 2 are arranged side by side along the width of the main unit cover 1, which conforms to the user's conventional operating habits and greatly reduces the probability of accidental touch. At the same time, the expansion interface component 4 and the operation component are arranged in the same end of the main unit cover 1, which facilitates the user's centralized operation and plugging and unplugging of external devices. The exposed interface design also ensures the compatibility of external devices of different specifications, effectively improving the ease of use of the product.

[0025] Specifically, the inner wall of the toothed limiting box 1504 is provided with vertical limiting tooth grooves, the outer wall of the wireless charging faceplate 1501 is provided with limiting ribs that slide in cooperation with the limiting tooth grooves, the inner diameter of the height limiting box 1502 is larger than the outer diameter of the spring 1503, and the outer diameter of the height limiting box 1502 is smaller than the inner diameter of the toothed limiting box 1504.

[0026] Through the above technical solution, the sliding cooperation of the limiting tooth groove and the limiting rib provides dual circumferential and vertical limiting for the lifting and lowering process of the wireless charging cover 1501, avoiding rotation and jamming during lifting and lowering, and ensuring smooth pressing and rebound. At the same time, through precise dimensional matching, motion interference between components is avoided, and the lifting and lowering stroke of the wireless charging cover 1501 is precisely controlled, further improving the operating feel and operational stability of the wireless charging component.

[0027] In use, when upward movement is required, the user lightly touches the upward button 3. Motor 7 receives the signal and starts in the forward direction. The output shaft of motor 7 drives the motor transmission gear 8 to rotate synchronously. The motor transmission gear 8, through its outer surface meshing, drives the spur gear 9 of the transmission shaft to rotate, which in turn drives the transmission shaft 12 to rotate coaxially. Simultaneously, the rotation of transmission shaft 12 drives the left bevel gear 14 and the right bevel gear 10 of the transmission shaft to rotate synchronously. The left bevel gear 14, through its outer surface meshing, drives the left screw bevel gear 13 to rotate, and the right bevel gear 10, through its outer surface meshing, drives the right screw bevel gear 11 to rotate synchronously. As the left screw bevel gear 13 and the right screw bevel gear 11 rotate... The rotational motion is converted into linear lifting motion through the ball bearing nut assembly, causing the left base 16 and right base 6 to extend downwards synchronously, thus raising the main unit cover 1. When the operating power of motor 7 reaches a preset threshold, motor 7 stops running, completing the upward limit. When descending, the user lightly touches the descent button 2, and motor 7 receives a signal to start in reverse. Through the same set of gear transmission chains, it drives the left screw bevel gear 13 and right screw bevel gear 11 to rotate in reverse. Through the ball bearing nut assembly, it drives the left base 16 and right base 6 to retract upwards synchronously, thus lowering the main unit cover 1. When the operating power of motor 7 reaches a preset threshold, motor 7 stops running, completing the descent limit. When the wireless charging component is needed, the device is locked in the hidden state: the user presses the wireless charging cover 1501, the spring 1503 is compressed, and the hook structure at the bottom of the wireless charging cover 1501 and the self-locking switch 1506 interlock and lock. At this time, the top surface of the wireless charging cover 1501 is flush with the top surface of the main unit cover 1, realizing the hidden storage of the wireless charging component. The device is unlocked and popped up: the user presses the wireless charging cover 1501 again, the spring 1503 rebounds, the hook structure of the wireless charging cover 1501 and the self-locking switch 1506 are unlocked and released, and the wireless charging cover 1501 pops up along the height limiting box 1502 to the preset height, forming a raised charging station, thus completing the unlocking and popping up.
