A laptop stand hinge structure

Abstract

This utility model belongs to the field of electronic accessories, specifically a laptop stand hinge structure. It addresses the problem that existing laptop stands, when extended to a small angle, cause the stand to gradually slide down when the user presses the keyboard. To prevent this sliding, the hinge damping force must be increased, but this results in the user having to overcome excessive damping force when the stand is extended to a large angle, leading to laborious and clumsy operation. The proposed solution includes a base, a turntable, a rotating arm, a tray, and a gravity compensation component. The turntable is mounted to the base via a rotating shaft. The rotating arm is connected to a first rotating seat via a first damping shaft, and the tray is connected to a second rotating seat via a second damping shaft. When the rotating arm is at a small angle, the gravity compensation component lengthens the counterweight arm to provide a greater compensation torque, preventing the tray from sliding down. When the rotating arm is at a large angle, the counterweight arm shortens to reduce the compensation torque, ensuring smooth rotation.

Description

Technical Field

[0001] This utility model relates to the field of electronic accessories technology, and in particular to a laptop stand hinge structure. Background Technology

[0002] With the increasing popularity of mobile work, laptop stands have become an important accessory for improving work efficiency. Ergonomically designed, laptop stands aim to provide a comfortable computer user experience. Their core function is to allow users to smoothly adjust the laptop's tilt and height, and to stably hover it at any angle, primarily achieved through the damping of the hinge.

[0003] However, there is a technical contradiction in the current design of laptop stand hinges: when the stand is extended to a small angle, pressing the keyboard will cause the stand to gradually slide down. In order to suppress the slide, the damping torque of the hinge must be increased to ensure stability. However, this means that when the stand is extended to a large angle, the user has to overcome excessive damping force, making the operation difficult and unsmooth, which goes against the original intention of smooth adjustment.

[0004] In other words, the preset value of the pivot damping cannot simultaneously satisfy the high damping characteristics required at low angles and the low damping characteristics required at high angles. Existing solutions are mostly compromises, selecting an intermediate damping value, but this means the experience at both low and high angles is not optimal. Some designs use a knob for manually adjusting the damping, but this increases the number of steps and disrupts the smoothness of the user experience. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as insufficient damping and instability at small angles, and excessive damping and poor rotation at large angles, by proposing a new hinge structure for a laptop stand.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A laptop stand hinge structure includes: Base; The rotating shaft is fixedly connected to the top of the base; The turntable, rotatably connected to the outer wall of the rotating shaft, is used to adjust the orientation of the support. Two first rotating seats are fixedly connected to both sides of the turntable, respectively; The first damping shaft is fixedly connected to the opposite side of the first rotating seat, providing a certain damping to facilitate stability at any angle; The rotating arm is rotatably connected to the outer wall of the first damping shaft; The second damping shaft is fixedly connected to one end of the rotating arm; The second rotating seat is rotatably connected to the outer wall of the second damping shaft; The tray, fixedly connected to the top of the second rotating seat, is used to support the laptop computer; A gravity compensation component is located on one side of the first rotating seat and is used to provide dynamic gravity compensation for the rotating arm. Specifically, when the rotating arm is at a small angle, the gravity compensation component provides a larger compensation torque to enhance stability; when the rotating arm is at a large angle, the gravity compensation component provides a smaller compensation torque to ensure smooth rotation.

[0007] In one possible design, the gravity compensation component includes: The fourth link is fixedly connected to the top of the turntable, providing support for the gravity compensation assembly; The third pivot is fixedly connected to the top of the fourth link; The third link is rotatably connected to the outer wall of the third shaft; The second pivot is fixedly connected to one end of the third link; The second connecting rod is rotatably connected to the outer wall of the second rotating shaft; The first rotating shaft is fixedly connected to one end of the second connecting rod; The first connecting rod is rotatably connected to the outer wall of the first rotating shaft, and the first connecting rod is fixedly connected to one side of the rotating arm.

[0008] One possible design also includes: The hanging ring is rotatably connected to the outer wall of the second rotating shaft. The bottom of the hanging ring is provided with a sliding groove, and one side is provided with a first rectangular through hole. The quick-release block engages with and slides in the groove at the bottom of the hanging ring. One side of the quick-release block is provided with a second rectangular through hole that matches the first rectangular through hole. The counterweight is fixedly connected to the bottom of the quick-release block; The T-shaped locking block engages with and slides through a rectangular through hole on one side of the hanging ring to lock the counterweight. A spring is disposed on one side of the T-shaped locking block, and the spring abuts against the hanging ring and the T-shaped locking block respectively through a spring seat.

[0009] In one possible design, rubber pads are provided at the four bottom corners of the base.

[0010] In one possible design, a storage box is provided on one side of the top of the turntable, and the storage box contains multiple counterweights of different masses, which can be selected by the user as needed.

[0011] In one possible design, the top of the quick-release block and one side of the T-shaped locking block are both provided with bevels.

[0012] In this application, rubber pads are provided at the four corners of the bottom of the base to prevent the base from sliding during use. The first rotating seat is provided on both sides of the turntable to provide a base for rotation. The laptop is placed on the tray. The height and pitch angle of the tray can be adjusted by rotating the rotating arm around the first damping axis and rotating the second rotating seat around the second damping axis. The orientation of the tray can be adjusted by rotating the turntable around the rotation axis.

[0013] When the rotating arm is raised to a small angle, i.e., when the tray is low, this is usually the typing angle. The torque on the first damping bearing is relatively large, which can easily cause the tray to slip when typing and pressing the keyboard. Therefore, a gravity compensation component is used to provide compensation to enhance stability at small angles. When the rotating arm angle decreases, the first link is fixed on the rotating arm and rotates clockwise around the first damping shaft. The first shaft pulls the second link to move, and the second link then pulls the third link to rotate counterclockwise around the third shaft. The fourth link provides support for the third shaft. At this time, the counterweight block hanging on the second shaft has a longer lever arm, providing a greater torque to counteract the gravity arm of the laptop acting on the first damping shaft, reducing the burden on the first damping shaft, enhancing the stability of the device, and preventing slippage when pressing the keyboard.

[0014] When the rotating arm is raised to a large angle, which is typically the viewing angle, the torque on the first damping bearing is small, requiring less gravity compensation. At this time, the third link rotates clockwise, shortening the lever arm of the counterweight, thus reducing the torque for gravity compensation and allowing the user to smoothly adjust the angle of the rotating arm. The hanging ring is rotatably connected to the second rotating shaft, ensuring the counterweight remains vertical. The counterweight is inserted into the groove at the bottom of the hanging ring via a quick-release block. The quick-release block presses against the T-shaped locking block outwards, stretching the spring. When the quick-release block aligns with the first rectangular hole on one side, the spring pulls back the T-shaped locking block, locking it in place and ensuring the hanging ring is connected. To remove the quick-release block, simply pull the T-shaped locking block outwards. If the user finds the counterweight compensation unsuitable, they can easily replace it with a counterweight of different weight.

[0015] Counterweights not in use are placed in a storage box located on the back of the turntable, which helps improve the turntable's stability.

[0016] Beneficial effects: The four-bar gravity compensation mechanism converts the rotation angle change of the rotating arm into automatic adjustment of the counterweight arm. When the stand is extended to a small angle for typing or working, the counterweight arm automatically lengthens, providing a larger compensation torque. This effectively counteracts the downward pressure torque generated by the laptop's gravity on the hinge, enhancing the stand's resistance to pressure and stability at low angles and preventing the stand from slipping due to keyboard operation. When the rotating arm is at a large angle for watching movies, the counterweight arm automatically shortens, and the compensation torque decreases accordingly, avoiding over-compensation and ensuring smooth and effortless rotation at high angles. This solves the contradiction that traditional fixed hinge damping cannot simultaneously meet the needs of both high and low angle use, achieving adaptive optimization of damping characteristics.

[0017] Furthermore, the quick-release counterweight structure allows users to quickly replace counterweights of different weights according to the weight of their laptops and usage habits. Installation and removal of the counterweights are easily accomplished by simply pulling the T-shaped locking block. The storage box design not only facilitates the storage of spare counterweights to prevent loss, but its location on the back of the turntable also helps lower the overall center of gravity, enhancing base stability and improving the user experience.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] In one embodiment: Refer to Figure 1-5 A rotating shaft structure includes: a base 1 with rubber pads 22 at its four corners, and a rotating shaft 2 fixedly connected to the center of the top of the base 1. A turntable 3 is rotatably connected to the outer wall of the rotating shaft 2, and two first rotating seats 4 are symmetrically arranged on both sides of the turntable 3. A first damping rotating shaft 5 is fixedly connected to the side of each first rotating seat 4 that is away from each other, and a rotating arm 6 is rotatably connected to the outer wall of the first damping rotating shaft 5. A second damping rotating shaft 7 is fixedly connected to one end of the rotating arm 6, and a second rotating seat 8 is rotatably connected to the outer wall of the second damping rotating shaft 7. A support plate 9 is fixedly connected to the top of the second rotating seat 8. A gravity compensation component is disposed on one side of the first rotating seat 4. A fourth connecting rod 16 is fixedly connected to the top of the turntable 3, and a third rotating shaft 15 is fixedly connected to the top of the fourth connecting rod 16. A third connecting rod 14 is rotatably connected to the outer wall of the third rotating shaft 15. A second connecting rod 12 is rotatably connected to the outer wall of the second rotating shaft 13, and the end of the second connecting rod 12 that is away from the second rotating shaft 13 is fixedly connected to the first rotating shaft 11. The first connecting rod 10 is rotatably connected to the outer wall of the first rotating shaft 11, and the first connecting rod 10 is fixedly connected to the side of the rotating arm 6 near the first rotating seat 4.

[0022] When the rotating arm 6 is raised to a small angle, the first link 10 rotates clockwise around the first damping shaft 5 with the rotating arm 6, pulling the second link 12 through the first shaft 11. The second link 12 then pulls the third link 14 to rotate counterclockwise around the third shaft 15 through the second shaft 13. At this time, the lever arm of the counterweight 18 mounted on the second shaft 13 becomes longer, generating a larger torque to counteract the gravitational torque exerted by the laptop on the first damping shaft 5, enhancing stability at small angles and preventing the tray 9 from sliding down when the keyboard is pressed. When the rotating arm 6 is raised to a larger angle, the clockwise rotation of the third link 14 shortens the lever arm of the counterweight 18, reducing the gravity compensation torque and facilitating smooth adjustment of the angle of the rotating arm 6 by the user. The counterweight 18 is inserted into the bottom groove of the hanging ring 17 via the quick-release block 19. The quick-release block 19 presses against the T-shaped locking block 20, causing it to compress the spring 21. When the second rectangular through hole of the quick-release block 19 aligns with the first rectangular through hole of the hanging ring 17, the spring 21 pushes the T-shaped locking block 20 back to complete the locking. When the counterweight 18 needs to be replaced, the quick-release block 19 can be unlocked by pulling the T-shaped locking block 20 outward.

[0023] This application can be used in the field of electronic product accessories, or in other fields applicable to this application.

[0024] In another embodiment: Reference Figure 1-5A laptop stand hinge structure is disclosed. The base 1 has rubber pads 22 at its four corners, each 3 mm thick. A storage box 23 is located on one side of the top of the turntable 3, containing multiple counterweights 18 of varying masses. The surfaces of the counterweights 18 are treated with an anti-slip coating. A hanging ring 17, made of aluminum alloy, is rotatably connected to the outer wall of the second hinge 13. Springs 21 are connected at both ends to the hanging ring 17 and a T-shaped locking block 20 via spring seats. When the rotating arm 6 is at a small angle, the counterweight 18 has its longest lever arm, resulting in the most significant gravity compensation effect. When the rotating arm 6 is at a large angle, the counterweight 18's lever arm shortens to its minimum, minimizing the gravity compensation torque. The storage box 23 is located on the back of the turntable 3, and its inner wall is lined with a cushioning pad to prevent the counterweights 18 from colliding with the inner wall and causing noise. A bearing is installed at the connection between the hanging ring 17 and the second rotating shaft 13 to reduce rotational friction resistance, ensure that the counterweight 18 always remains vertical, and improve the stability of gravity compensation.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
