Description

Technical Field

[0001] This disclosure relates to the field of electronic device technology, and more particularly to a raised screen structure and a laptop computer. Background Technology

[0002] Many users on the market choose to purchase external stands or bases to raise the screen height for ergonomic purposes. The downside of this approach is that it requires extra carrying and increases the burden of travel, contradicting the lightweight design philosophy of laptops. Some users opt for highly adjustable external monitors to enhance the visual experience, but this sacrifices the laptop's portability. While this solution is powerful, it doesn't integrate seamlessly with the laptop's design, making it impractical for users prioritizing portability. Utility Model Content

[0003] This application provides an elevated screen structure and a laptop computer to at least solve one of the technical problems existing in the prior art.

[0004] In a first aspect, this application provides a screen-raising structure for use in a laptop computer, the laptop computer including a hinge and a screen, the screen-raising structure comprising:

[0005] gear;

[0006] The gear rail meshes with the gear for transmission;

[0007] A linkage assembly is rotatably connected to the gear rail, the rotating shaft, and the screen; the linkage assembly is configured to retract or expand to drive the screen to move vertically up and down in a straight line when the gear rotates counterclockwise or clockwise.

[0008] In one possible implementation, the linkage assembly includes:

[0009] The first connecting rod has its first end rotatably connected to the rotating shaft.

[0010] The second connecting rod has its first end rotatably connected to the second end of the first connecting rod, and its second end rotatably connected to the first end of the gear rail.

[0011] The third link has its first end rotatably connected to the second end of the first link, and its second end rotatably connected to the screen.

[0012] In one embodiment, both the connecting rod assembly and the gear rail are provided in two sets, symmetrically arranged on both sides of the screen.

[0013] In one embodiment, the raised screen structure further includes a driving component connected to the gear transmission to drive the gear to rotate clockwise or counterclockwise.

[0014] In one embodiment, the driving component includes: a driving member having a rotatable output end;

[0015] The first bevel gear is fixedly installed on the output end;

[0016] The second bevel gear is fixedly connected to the gear, and the second bevel gear is perpendicularly meshed with the first bevel gear.

[0017] In one possible implementation, the drive element is a motor with a self-locking function, used to keep the screen at a preset height.

[0018] In one possible implementation, the laptop computer further includes:

[0019] The first component A is fixedly connected to the outside of the screen with a gap between them;

[0020] The second A component is disposed in the gap and is slidably connected to the first A component, and the bottom of the second A component is fixedly connected to the gear.

[0021] In one embodiment, slide rail grooves are provided on both sides of the first A component, and the second A component is slidably connected to the slide rail grooves.

[0022] In one embodiment, the laptop computer further includes a resilient cable electrically connected to the screen.

[0023] Secondly, this application provides a laptop computer, including a hinge, a screen, and further including a first A component, a second A component, and a screen-raising structure in any of the above-described possible embodiments; wherein the first A component is fixedly connected to the screen, and the second A component is fixedly connected to the gear of the screen-raising structure.

[0024] Compared with existing technologies, the advantages of this application are as follows: 1) This application raises the screen structure by setting up a linkage assembly, gears, and a gear rail. When the gear rotates counterclockwise, it synchronously drives the gear rail to move away from the gear, thereby causing the linkage assembly connected to it to fold and raise the screen upwards to a preset height. When the gear rotates clockwise, it synchronously drives the gear rail to move closer to the gear, thereby causing the linkage assembly connected to it to unfold and drive the screen downwards. Therefore, by adopting the screen-raising structure of this application, the screen height can be adjusted, and the screen angle can be adjusted synchronously through the pivot, improving ergonomics, reducing neck and shoulder fatigue caused by prolonged use, and making it suitable for various scenarios.

[0025] 2) The screen-raising structure of this application can raise the screen and increase the airflow of the laptop, which helps to improve the heat dissipation performance.

[0026] 3) This application raises the screen structure, eliminating the need for an additional screen stand or base, reducing the burden and cost of the device, meeting the lightweight and practical needs of laptops, and improving portability and integrated design.

[0039] To make the objectives, features, and advantages of this disclosure more apparent and understandable, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0040] Firstly, such as Figure 1-4 As shown, this application provides a screen-raising structure 1 applied to a laptop computer 2. The laptop computer 2 includes a hinge 21 and a screen 22. The screen-raising structure 1 includes:

[0041] Gear 11;

[0042] The gear 12 meshes with the gear 11 for transmission.

[0043] Linkage assembly 13 is rotatably connected to gear rail 12, rotating shaft 21 and screen 22; linkage assembly 13 is configured to retract or expand to drive screen 22 to move vertically up and down in a straight line when gear 11 rotates counterclockwise or clockwise.

[0044] This application's screen-raising structure 1, through the arrangement of a linkage assembly 13, a gear 11, and a gear rail 12, allows the gear rail 12 to move away from the gear 11 when the gear 11 rotates counterclockwise, thereby folding the linkage assembly 13 and raising the screen 22 to a preset height. When the gear 11 rotates clockwise, the gear rail 12 moves closer to the gear 11, thereby unfolding the linkage assembly 13 and lowering the screen 22. Therefore, using this screen-raising structure 1 allows for adjustment of the screen 22's height, while simultaneously adjusting the screen 22's angle via the hinge 21, improving ergonomics and reducing neck and shoulder fatigue from prolonged use, making it suitable for various scenarios. This screen-raising structure 1 also increases airflow in the laptop while raising the screen 22, contributing to improved heat dissipation. Furthermore, using this screen-raising structure 1 eliminates the need for an additional screen stand or base, reducing equipment burden and cost, meeting the portability and practicality requirements of laptops, and enhancing portability and integrated design.

[0045] In some embodiments, such as Figure 1As shown, the linkage assembly 13 includes:

[0046] The first connecting rod 131 has its first end rotatably connected to the rotating shaft 21;

[0047] The second link 132 has its first end rotatably connected to the second end of the first link 131 and its second end rotatably connected to the first end of the gear 12.

[0048] The third link 133 has its first end rotatably connected to the second end of the first link 131, and its second end rotatably connected to the screen 22.

[0049] For example, the linkage assembly 13 and the gear rail 12 are each provided in two sets, symmetrically arranged on both sides of the screen 22.

[0050] like Figure 3 , Figure 5 As shown, the gear rail 12 is a long strip structure, and one end of the gear rail 12 has teeth 121 that mesh with the gear 11 along its length. There are two sets of gear rails 12, which are respectively located above and below the gear 11 and are connected to the gear 11 through the teeth 121 provided on them.

[0051] For example, bearings are used to achieve the rotational connections between the first link 131, the second link 132, the third link 133, the rotating shaft 21, and the screen 22. Alternatively, pins can be used to achieve the rotational connections, or other existing known methods can be employed.

[0052] For example, such as Figure 3 As shown, the first end of the third link 133 is rotatably connected to the second end of the first link 131, and the second end of the first link 131 is rotatably connected to the first end of the second link 132. Therefore, the rotatable connection between the first, second, and third links is achieved using bearings or pins, meaning that the rotatable connection points of the three links are on the same straight line. Thus, the total thickness of the three links when stacked is approximately 6mm. This stacking design saves internal space while ensuring structural stability, meeting the requirements of thin and light designs for laptops.

[0053] In some embodiments, such as Figure 5-6 As shown, the raised screen structure 1 also includes a drive component 14, which is connected to the gear 11 to drive the gear 11 to rotate clockwise or counterclockwise. This application achieves automatic adjustment of the height and angle of the screen 22 by setting the drive component 14 to drive the gear 11 to rotate clockwise or counterclockwise, combined with the linkage assembly 13.

[0054] Furthermore, such as Figure 5As shown, the drive assembly 14 includes: a drive member 141 having a rotatable output end 1411;

[0055] The first bevel gear 142 is fixedly installed on the output end 1411;

[0056] The second bevel gear 143 is fixedly connected to the gear 11, and the second bevel gear 143 is perpendicularly meshed with the first bevel gear 142.

[0057] For example, the drive unit 141 is a motor with a self-locking function, used to keep the screen 22 at a preset height.

[0058] In this application, the rotation of the gear 11 is precisely controlled by the drive component 141. This allows the gear to smoothly drive the gear rail, which in turn smoothly drives the linkage assembly, ensuring the screen remains stable and smooth during vertical movement.

[0059] like Figure 5 As shown, the rotation axis of the output end 1411 of the drive component 141 is perpendicular to the rotation axis of the gear 11. This allows the drive component 141 to output rotational power, simultaneously driving the first bevel gear 142 to rotate. Because the second bevel gear is perpendicularly meshed with the first bevel gear, the rotation angle output by the drive component is converted by 90°, thereby driving the gear rail 12 to move horizontally. Therefore, this application precisely achieves the conversion of transmission direction by setting the first bevel gear, the second bevel gear, and the drive component, while ensuring high efficiency and smoothness during transmission. Furthermore, this application uses the angle-converting drive assembly to drive the gears and linkage assembly, realizing the vertical movement of the screen. When the screen reaches a preset height, the self-locking function of the drive component fixes the screen at the preset height, ensuring that the screen remains stable during use.

[0060] Taking a laptop as an example, this application achieves compact and efficient transmission within the limited internal space of a laptop by employing a first bevel gear and a second bevel gear, while also considering ergonomics and product aesthetics. Furthermore, through precise transmission and control, the accuracy and stability of screen adjustment can be effectively improved, further enhancing the overall competitiveness of the product.

[0061] In some embodiments, such as Figure 6-7 As shown, the laptop computer 2 also includes:

[0062] The first component A, 23, is fixedly connected to the outside of the screen 22 with a gap 231 between them;

[0063] The second A piece 24 is disposed in the gap 231 and is slidably connected to the first A piece 23. The bottom of the second A piece 24 is fixedly connected to the gear 11.

[0064] For example, the first A piece 23 has slide rail grooves 232 on both sides, and the second A piece 24 is slidably connected to the slide rail grooves 232. Specifically, as shown... Figure 6 As shown, sliders 241 are fixedly connected to the left and right sides of the second A piece 24, and the sliders 241 are slidably connected in the slider groove 232.

[0065] For example, the screen-raising structure 1 is located below the screen 22 and is rotatably connected to the screen 22 via the third link 133 of the linkage assembly. When the drive member 141 drives the gear 11 to rotate clockwise or counterclockwise, it synchronously drives the gear rail 12 to move back and forth, thereby raising or lowering the linkage assembly and the screen connected to the linkage assembly.

[0066] Taking a laptop computer as an example, this application improves the existing conventional one-piece A component into a separate component, that is, it has two A components, one of which is a movable A component (i.e., the first A component), which is used to fix it to the screen 22. The other is a fixed A component (i.e., the second A component), which is used to install the drive component 141 and the gear 11 and does not move with the first A component.

[0067] When the screen is raised, the first component A moves synchronously, covering the back component of the screen and preventing it from being exposed. This design not only ensures the consistency and aesthetics of the overall appearance but also effectively protects internal components from dust and accidental damage. Furthermore, the design of the slide rail 232 considers the smoothness and precision of movement, ensuring that the screen (i.e., the display screen) does not interfere with other transmission mechanisms during its raising and lowering process, further enhancing the stability and durability of the overall system.

[0068] For example, the laptop 2 also includes a cable 25 with elastic resilience, which is electrically connected to the screen 22.

[0069] In this application, the cable design employs a spring-like structure (with elastic restoring capability) to address the potential for cable stretching during screen 22 lifting. The spring-loaded cable 25 automatically adjusts its length during lifting, preventing excessive stretching due to screen 22 movement and ensuring the cable doesn't become damaged or jammed. This design not only improves the reliability of system components but also ensures the cable remains within a safe range, reducing the risk of damage due to excessive cable tension.

[0070] Secondly, such as Figure 1 As shown, this application also provides a laptop computer 2, including a hinge 21, a screen 22, a first A component 23, a second A component 24, and a screen-raising structure 1 in any of the above embodiments; wherein, the first A component 23 is fixedly connected to the screen 22, and the second A component 24 is fixedly connected to the gear 11 of the screen-raising structure 1.

[0071] The laptop computer 2 with this raised screen structure 1 can better meet users' needs for portability, comfort, and functionality, and achieve differentiated competition in the market. This application integrates the raised screen structure 1 directly into the laptop computer, making the laptop's appearance integrated without affecting the product's aesthetics, improving ease of use, and expanding the laptop's usage scenarios, such as remote conferencing, design work, and long-term work, further enhancing the laptop's market appeal.
