Description

Technical Field

[0001] This utility model relates to the field of notebook computer auxiliary tools, and more specifically, to an electric height-adjustable notebook computer stand. Background Technology

[0002] In modern life, laptops have become essential tools for work, study, and entertainment. As people increasingly focus on healthy office work and comfortable user experiences, laptop stands are becoming more and more widely used. Laptop stands can raise the computer to a suitable height, keeping the user's line of sight parallel to the screen, effectively reducing neck and shoulder pressure and preventing cervical spondylosis. At the same time, they can also enhance the laptop's heat dissipation, preventing overheating that could affect performance and lifespan.

[0003] Currently, various types of laptop stands exist on the market. For example, Chinese patent CN214171848U discloses a height-adjustable laptop stand, which includes a base, at least one telescopic rod, at least one hinge assembly, and a support plate. Each telescopic rod includes a fixed rod, a movable rod, and a connector. The fixed rod is connected to the base, the movable rod is sleeved on the fixed rod and moves relative to the fixed rod to change the height of the telescopic rod, and the connector detachably connects the fixed rod and the movable rod. Each hinge assembly includes a hinge fixing seat disposed at the end of the telescopic rod and a damping hinge mounted in the hinge fixing seat. The support plate includes a plate body and a limiting member disposed on the plate body. The plate body is rotatably connected to each damping hinge to change the tilt angle of the plate body, and the limiting member is disposed at the front end of the plate body to limit and block the laptop. Although this stand can achieve stepless adjustment of the height and tilt angle of the support plate, which is convenient for users, it still has certain limitations. The support plate is mounted on a pivot bracket at the end of the telescopic rod via a damping pivot. It only allows adjustment of the support plate's height and tilt angle, but not its circumferential angle. When users need to adjust the laptop's circumferential angle, they have to rotate and move the entire laptop stand, which is extremely inconvenient. Utility Model Content

[0004] The purpose of this utility model is to provide an electrically adjustable laptop stand to solve the problem mentioned in the background art, where users have to rotate and move the entire laptop stand when they need to adjust the circumferential angle of the laptop, which is extremely inconvenient.

[0005] To achieve the above objectives, this utility model provides an electric height-adjustable laptop stand, including a base. A height-adjustable rotating component is mounted on the top of the base, and a support plate is mounted on the top of the height-adjustable rotating component. The top of the height-adjustable rotating component is connected to one side of the bottom of the support plate. A height-adjustable drive motor is mounted on the base, and a drive wheel is mounted on the output shaft of the height-adjustable drive motor. The drive wheel drives the height-adjustable rotating component to move via a belt for height adjustment. The height-adjustable rotating component can be manually rotated to rotate the support plate. An angle adjustment component is rotatably connected to the top of the height-adjustable rotating component via a pin, and the support plate is fixed to the angle adjustment component by bolts.

[0006] This setup uses a base to support the overall structure. The lifting drive motor drives the drive wheel to rotate, and the rotation is transmitted to the lifting and rotating components via a belt to achieve electric lifting. The connection design between the lifting and rotating components and the support plate allows manual rotation of the support plate to adjust the circumferential angle. The angle adjustment component is connected to the lifting and rotating components via a pin to adjust the tilt angle of the support plate.

[0007] Preferably, the support plate has several heat dissipation holes, and the surface of the support plate is adhered with an anti-slip pad.

[0008] This feature includes ventilation holes on the support plate to enhance airflow and accelerate heat dissipation from the bottom of the laptop; the surface anti-slip pads increase friction to prevent the laptop from sliding.

[0009] Preferably, a lower baffle is installed at the lower end of the support plate.

[0010] This feature includes a lower baffle at the bottom of the support plate, which acts as a physical barrier to limit the laptop's downward sliding tendency when tilted.

[0011] Preferably, the lifting and rotating component includes a fixed cylinder and a rotating lifting rod. A lead screw is installed inside the fixed cylinder, and a driven wheel is installed at the lower end of the lead screw. The drive wheel drives the driven wheel to rotate via a belt. A lead screw slider is threaded onto the lead screw, and a rotating lifting block is rotatably connected to the top of the lead screw slider via an upper bearing. The rotating lifting block is fixed to the lower end of the rotating lifting rod.

[0012] This feature incorporates a lead screw drive structure for the lifting and rotating components. The drive wheel rotates the driven wheel and lead screw via a belt, causing the lead screw slider to move vertically along the lead screw. This movement, in turn, drives the rotating lifting rod to rise and fall via the rotating lifting block. The upper bearing allows the rotating lifting rod to rotate freely relative to the lead screw slider, enabling manual rotation.

[0013] Preferably, a limiting ring is installed on the bottom outer side of the lead screw slider, the outer wall of the limiting ring is provided with a vertical guide block, the inner wall of the fixed cylinder is provided with a vertical guide groove, and the limiting ring slides vertically with the guide block and the guide groove.

[0014] The guide block with the limit ring is slidably engaged with the guide groove of the fixed cylinder, which restricts the screw slider from rotating synchronously with the screw and only allows it to move vertically.

[0015] Preferably, a sealing ring is installed on the top inner wall of the fixed cylinder.

[0016] This feature includes a sealing ring at the top of the fixed cylinder to prevent dust, moisture, and other impurities from entering the internal transmission structure.

[0017] Preferably, the bottom of the driven wheel is rotatably connected to the base via a lower bearing, and the bottom end of the fixed cylinder is fixed to the base with bolts.

[0018] This design connects the driven wheel to the base via a lower bearing to reduce rotational friction; the fixed cylinder is secured to the base with bolts to ensure the overall structure is stable.

[0019] Preferably, the upper end of the rotating lifting rod is connected to the angle adjusting component via a pin, and a damping ring is fitted at the connection.

[0020] This feature allows the rotating lifting rod and the angle adjustment component to rotate via a pin connection, while the damping ring provides resistance through friction, enabling the angle adjustment component to be fixed in any position.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0022] In this electrically adjustable laptop stand, the stand, through the cooperation of a lifting and rotating component and an angle adjustment component, can simultaneously adjust the height, circumferential rotation angle, and tilt angle of the support plate.

[0023] The electrically driven lifting structure replaces the traditional manual adjustment. The height can be adjusted by simply operating the motor, avoiding the risk of bumping the laptop when operating manually. The adjustment process is also smoother and less strenuous.

[0024] The rotating lifting rod is connected to the lead screw slider through the upper bearing, which can manually drive the support plate to rotate 360° in all directions. This solves the problem that the existing brackets need to be moved as a whole to adjust the circumferential angle, and is especially suitable for screen sharing in multi-person collaborative scenarios.

[0025] The angle adjustment component and the rotating lifting rod are connected by a pin with a damping ring, which can flexibly adjust the tilt angle of the support plate to meet the viewing posture needs of different users, and the damping structure can ensure that it will not loosen after the angle is fixed.

[0026] The lead screw slider cooperates with the guide groove of the fixed cylinder through the guide block of the limit ring to ensure no deviation or shaking during the lifting process, thereby improving the load-bearing stability of the bracket;

[0027] The anti-slip pads on the surface of the support plate and the lower baffle at the bottom work together to effectively prevent the laptop from slipping during angle adjustment or use, ensuring device safety.

[0028] The sealing ring at the top of the fixed cylinder can prevent dust and impurities from entering the internal transmission structure, reduce component wear, and extend the service life of the bracket. Attached Figure Description

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] This utility model provides an electrically adjustable laptop stand, such as... Figure 1 , Figure 2As shown, the device includes a base 1, a lifting and rotating component 3 mounted on the top of the base 1, a support plate 2 mounted on the top of the lifting and rotating component 3, the top of the lifting and rotating component 3 connected to the bottom side of the support plate 2, a lifting drive motor 4 mounted on the base 1, a drive wheel 41 mounted on the output shaft of the lifting drive motor 4, the drive wheel 41 drives the lifting and rotating component 3 to move via a belt to perform lifting and lowering operations, the lifting and rotating component 3 drives the support plate 2 to rotate by manual rotation, the top of the lifting and rotating component 3 is rotatably connected to an angle adjustment component 321 via a pin, and the support plate 2 is fixed to the angle adjustment component 321 by bolts.

[0038] The base 1 serves as the overall support foundation, with the lifting and rotating component 3 mounted on its top as the core adjustment structure. A support plate 2 is connected to the top for placing the laptop. When the lifting drive motor 4 is working, its output shaft drives the drive wheel 41 to rotate, which in turn drives the lifting and rotating component 3 via belt transmission to achieve electric lifting. The lifting and rotating component 3 can also be rotated manually, thereby causing the support plate 2 to rotate synchronously to adjust the circumferential angle. The top of the lifting and rotating component 3 is rotatably connected to the angle adjustment component 321 via a pin, and the support plate 2 is fixed to the angle adjustment component 321 to achieve tilt angle adjustment. Integrating electric lifting, manual rotation, and angle adjustment functions, this design breaks through the limitations of traditional stand adjustments. Through the coordinated operation of various components, it meets users' multi-dimensional needs for height, circumferential angle, and tilt angle, significantly improving operational convenience.

[0039] In this embodiment, as Figure 3 As shown, the support plate 2 has several heat dissipation holes 21, and the surface of the support plate 2 is covered with an anti-slip pad 23.

[0040] The ventilation holes 21 on the support plate 2 provide channels for air circulation, accelerating heat dissipation from the bottom of the laptop; the anti-slip pads 23 adhered to the surface of the support plate 2 increase the friction of the contact surface, limiting the laptop's sliding. The ventilation holes 21 effectively improve the laptop's heat dissipation conditions, preventing overheating from affecting performance; the anti-slip pads 23 enhance the stability of the laptop and prevent it from slipping during adjustment or use.

[0041] Specifically, such as Figure 3 As shown, a lower baffle 22 is installed at the lower end of the support plate 2.

[0042] The lower baffle 22 installed at the lower end of the support plate 2 forms a physical barrier, which, together with the surface of the support plate 2, constitutes a limiting space to restrict the downward trend of the laptop when tilted. The lower baffle 22 and the anti-slip pad 23 form a double protection, further reducing the risk of the laptop slipping due to excessive tilt angle or accidental contact, and improving the safety of device placement.

[0043] Furthermore, such as Figure 4 , Figure 5As shown, the lifting and rotating component 3 includes a fixed cylinder 31 and a rotating lifting rod 32. A lead screw 33 is installed inside the fixed cylinder 31. A driven wheel 34 is installed at the lower end of the lead screw 33. The drive wheel 41 drives the driven wheel 34 to rotate via a belt. A lead screw slider 331 is threaded onto the lead screw 33. A rotating lifting block 334 is rotatably connected to the top of the lead screw slider 331 via an upper bearing 333. The rotating lifting block 334 is fixed to the lower end of the rotating lifting rod 32.

[0044] The lifting and rotating component 3 consists of a fixed cylinder 31 and a rotating lifting rod 32. A driven wheel 34 is installed at the lower end of a lead screw 33 inside the fixed cylinder 31. A drive wheel 41 drives the driven wheel 34 and the lead screw 33 to rotate via a belt, causing the lead screw slider 331 on the lead screw to move vertically along the lead screw. The top of the lead screw slider 331 is rotatably connected to the rotating lifting block 334 via an upper bearing 333. The rotating lifting block 334 is fixed to the lower end of the rotating lifting rod 32. Therefore, the lifting and lowering of the lead screw slider 331 can synchronously lift and lower the rotating lifting rod 32, and the rotating lifting rod 32 can rotate freely via the upper bearing 333. The lead screw 33 transmission ensures a smooth and precise lifting process with strong load-bearing capacity. The independent rotation function of the rotating lifting rod 32 allows the support plate 2 to be adjusted in circumferential angle without overall movement, making operation flexible and efficient.

[0045] Furthermore, such as Figure 4 , Figure 5 As shown, a limit ring 332 is installed on the outer bottom of the lead screw slider 331. A vertical guide block is provided on the outer wall of the limit ring 332, and a vertical guide groove is provided on the inner wall of the fixed cylinder 31. The limit ring 332 slides vertically with the guide block and the guide groove.

[0046] The limiting ring 332 on the outer side of the bottom of the lead screw slider 331 has a guide block on its outer wall that forms a vertical sliding fit with the guide groove on the inner wall of the fixed cylinder 31, restricting the lead screw slider 331 from rotating synchronously with the lead screw 33 and allowing it to move only vertically. Through the guiding fit between the limiting ring 332 and the fixed cylinder 31, the lifting and lowering process is prevented from becoming stuck or offset due to the rotation of the lead screw slider 331, ensuring a stable and smooth lifting process and improving the reliability of the structure.

[0047] Furthermore, such as Figure 4 , Figure 5 As shown, a sealing ring 311 is installed on the top inner wall of the fixed cylinder 31.

[0048] The sealing ring 311 on the inner wall of the top of the fixed cylinder 31 can prevent dust, moisture and other impurities from entering the interior of the fixed cylinder 31, protecting the transmission components such as the lead screw 33 and the upper bearing 333. This reduces the wear of internal components by impurities, extends the service life of the lifting and rotating components 3, and reduces maintenance frequency and costs.

[0049] Furthermore, such as Figure 4 , Figure 5As shown, the bottom of the driven wheel 34 is rotatably connected to the base 1 via the lower bearing 341, and the bottom end of the fixed cylinder 31 is fixed to the base 1 by bolts.

[0050] The driven wheel 34 is connected to the base 1 at its bottom via a lower bearing 341, reducing frictional resistance during rotation. The bottom of the fixed cylinder 31 is fixed to the base 1 with bolts, ensuring a rigid connection of the overall structure. The lower bearing 341 improves the smoothness of rotation of the driven wheel 34 and reduces the energy consumption of the lifting drive motor 4. The stable connection between the fixed cylinder 31 and the base 1 enhances the overall stability of the bracket and prevents swaying during lifting or rotation.

[0051] Furthermore, such as Figure 4 , Figure 5 As shown, the upper end of the rotating lifting rod 32 is connected to the angle adjusting component 321 via a pin, and a damping ring is fitted at the connection.

[0052] The upper end of the rotating lifting rod 32 is connected to the angle adjusting component 321 via a pin, enabling relative rotation between the two. A damping ring fitted at the connection provides resistance through friction, allowing the angle adjusting component 321 to be fixed in any rotational position. This allows the support plate 2 to flexibly adjust the tilt angle, and the damping ring ensures that the angle remains fixed and does not loosen, meeting the viewing posture needs of different users, and providing a smooth and stable adjustment feel.

[0053] When using the electric height-adjustable laptop stand of this utility model, the lifting drive motor 4 starts when the height of the support plate 2 needs to be adjusted. Its output shaft drives the drive wheel 41 to rotate. The drive wheel 41 transmits power to the driven wheel 34 in the lifting and rotating component 3 via a belt, causing the driven wheel 34 to drive the lead screw 33 to rotate synchronously. Since the lead screw slider 331 is threadedly connected to the lead screw 33, and the limiting ring 332 at the bottom of the lead screw slider 331 slides in cooperation with the guide groove on the inner wall of the fixed cylinder 31 through the guide block, the rotational motion of the lead screw 33 is converted into the vertical linear motion of the lead screw slider 331. The lead screw slider 331 drives the rotating lifting block 334 and the rotating lifting rod 32 to rise and fall synchronously through the upper bearing 333, ultimately realizing the height adjustment of the support plate 2. The entire process is driven by a motor, requiring no manual force, and the guide structure ensures smooth lifting without deviation.

[0054] If the circumferential angle of the support plate 2 needs to be adjusted, the user can directly rotate the support plate 2 manually. At this time, the rotating lifting rod 32 rotates relative to the upper bearing 333 at the top of the lead screw slider 331 through the rotating lifting block 334. That is, the rotating lifting rod 32 can rotate freely around the central axis of the lead screw slider 331, while the lead screw slider 331 remains stationary due to the constraint of the limiting ring 332. This structural design allows the support plate 2 to achieve 360° circumferential rotation with the rotating lifting rod 32, allowing the orientation of the laptop to be adjusted without moving the base 1, making the operation flexible and convenient.

[0055] When adjusting the tilt angle of the support plate 2, the user can directly move the support plate 2 to rotate it around the connecting pin between the angle adjusting component 321 and the rotating lifting rod 32. Because a damping ring is fitted at the connection point, the damping ring provides stable resistance through friction. When the support plate 2 rotates to the target angle, the damping force can fix the relative position of the angle adjusting component 321 and the rotating lifting rod 32, ensuring that the support plate 2 will not change its angle due to its own weight or slight contact. This process requires no additional locking components, and the adjusted angle remains stable, meeting the needs of different usage postures.

[0056] During the above adjustment process, the heat dissipation holes 21 of the support plate 2 always maintain air circulation to dissipate heat from the bottom of the laptop in a timely manner; the anti-slip pad 23 on the surface cooperates with the lower baffle 22 at the bottom to prevent the laptop from slipping during adjustment or use through the dual effects of friction and physical obstruction; the sealing ring 311 at the top of the fixing cylinder 31 prevents dust from entering the interior, protects components such as the lead screw 33 and the upper bearing 333, and ensures the long-term stable operation of the overall structure.

[0057] Finally, it should be noted that the electronic components in the lifting drive motor 4 and other components in this embodiment are all general standard parts or parts known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. In the idle part of this device, all the above-mentioned electrical components are connected by wires respectively.
