[0028] Figures 1A to 1E The figure shows the basic structure of an expansion display module for a laptop computer according to one embodiment of the present invention. The module includes an expansion bracket body 11, an expansion connector 12, and at least one expansion display 2. The expansion connector 12 is hingedly connected to an edge of the expansion bracket body 11, and a connecting rail 13 is provided on the edge of the expansion connector 12 facing away from the bracket body 11.

[0029] The edge of the extended display 2 is provided with a connecting groove 21 corresponding to the connecting rail 13. The connecting groove 21 is configured to slide with the connecting rail 13, thereby achieving a stable connection between the extended display 2 and the bracket body 11. This design not only provides a stable physical connection, but also ensures the flexibility of the display, allowing users to adjust the angle and position of the display according to actual needs.

[0030] The connecting rail 13 has an I-shaped cross-section, providing additional stability. It features protrusions on either side that snap into corresponding grooves within the connecting slot 21. The connecting slot 21 is also I-shaped, with an internal design that matches the rail, ensuring smooth sliding within the slot without dislodging. This design is widely applicable in applications requiring a stable sliding fit, such as in some mechanical equipment, where the rail and slot ensure stable movement of moving parts.

[0031] In practical applications, I-shaped rails and chutes offer excellent support and deformation resistance. For example, under high loads, the I-shaped structure can better disperse pressure, reducing single-point stress concentrations and thus extending the life of the equipment. The material selection for rails and chutes is also crucial, with high-strength alloys or engineering plastics typically used to ensure reliability and durability under intense use.

[0032] In a business meeting, users can quickly connect an extended monitor to their laptop to present multiple reports or presentations. In daily office work, users can use the extended monitor to view multiple windows and efficiently multitask. This flexible display method not only improves work efficiency but also effectively reduces the operational burden of frequent window switching.

[0033] In some cases, such as during meetings or presentations, the use of extended displays significantly improves productivity. Users can display complex charts and data on the extended display while simultaneously operating the control interface on the primary display. This multitasking capability not only saves time but also reduces the hassle of switching back and forth between windows, avoiding the inconvenience caused by operational errors.

[0034] Figure 1C 、 Figure 2A and Figure 2BThe figure shows that the extension connector 12 is hinged to the edge of the bracket body 11 via a biaxial hinge 14. The biaxial hinge 14 includes a first rotating shaft 141 and a second rotating shaft 142, which are parallel to each other. The first rotating shaft 141 has a first fixing portion 141a at each end, which is fixedly connected to the bracket body 11. The second rotating shaft 142 has a second fixing portion 142a at each end, which is fixedly connected to the extension connector 12.

[0035] The design of the biaxial hinge 14 enables the expansion connector 12 to rotate freely in multiple directions, greatly improving the operability of the expansion display 2. For example, the user can rotate the expansion display 2 to the optimal viewing angle, or fold it to save space.

[0036] The biaxial hinge 14 is precisely designed to allow the extension connector 12 to rotate freely in both the horizontal and vertical directions. The first rotating shaft 141 and the second rotating shaft 142 are precisely matched via internal gears to ensure smooth and stable rotation.

[0037] The core of a biaxial hinge lies in its high-precision machining and assembly processes, which ensure smooth and stable rotation. Specifically, the gear tooth profile must be designed with extreme precision to prevent binding or loosening during rotation. Furthermore, the choice of bearings is crucial; high-quality bearings significantly reduce rotational resistance and extend service life.

[0038] During design work, users can rotate the extended display to the same viewing angle as the primary display, allowing for comparison and editing of design drawings. If desk space is limited, users can fold the display away to keep their desk tidy. This flexibility and ease of use make the extended display module an excellent choice for a variety of use cases.

[0039] For example, when working on a complex design project, users can adjust the extended monitor to the optimal viewing angle to view both design drawings and reference materials simultaneously. This multi-view display greatly improves design efficiency and reduces the inconvenience of frequent window switching. Furthermore, when not in use, the extended monitor can be folded away, keeping the workspace tidy.

[0040] like Figure 1C 、 Figure 4A and Figure 4B As shown, the expansion connector 12 rotates between an extended position and a folded position via a biaxial hinge 14. When the expansion connector 12 is in the extended position, the angle between the expansion connector 12 and the bracket body 11 is 220°. When the expansion connector 12 is in the folded position, the angle between the expansion connector 12 and the bracket body 11 is 0°.

[0041] This design allows users to freely adjust the angle of the extended display 2 according to specific needs. Whether it is an office scene that requires multitasking or a professional application that needs to display a variety of information, this flexible adjustment mechanism can meet the different needs of users.

[0042] The angle between the first and second axes 141 and 142 of the hinge is designed to range from 0° to 220°. This optimal angle, determined through precise calculations, meets the requirements of most usage scenarios. To enhance user comfort, the hinge is also coated with a protective silicone layer, which not only aesthetically pleasing but also prevents accidental injury when adjusting the angle.

[0043] The hinge's rotation angle is designed with ergonomic principles in mind, ensuring an optimal viewing experience in various scenarios. For example, when developing a program, users can adjust the extended display to a wide angle to view code and runtime results simultaneously, improving development efficiency. Adjusting the display to the right angle provides a better viewing experience when watching videos or conducting remote meetings.

[0044] Specifically, developers can review code on the extended monitor while running and testing programs on the primary monitor. This layout not only improves productivity but also reduces the inconvenience of frequent window switching. When watching videos, users can adjust the extended monitor to the optimal viewing angle for a better viewing experience and avoid visual fatigue caused by poor viewing angles.

[0045] Figure 2B An embodiment is shown having a damping mechanism 15 for fixing the rotation angle of the extension connector 12 relative to the bracket body 11. The damping mechanism 15 ensures the stability and safety of the extension connector 12 during use.

[0046] The damping mechanism 15 is typically a friction damper encased in a circular sleeve. The inner surface of the sleeve contacts the hinge shaft, and adjusting the tightness of the sleeve modifies the frictional force, thereby controlling the resistance to rotation. The inner surface of the sleeve can be made of rubber or polyurethane, providing appropriate resistance while also reducing wear and noise.

[0047] The use of the damping mechanism 15 not only provides additional safety but also enhances the user experience. By adjusting the damping force, the user can more easily adjust the angle of the extended display 2 without affecting operation due to sliding too fast or too slow. The damping mechanism is easy to adjust; the user simply turns the adjustment screw to change the friction force to achieve the desired damping effect.

[0048] In actual use, the damping mechanism is very easy to adjust. For example, users can adjust the rotational resistance of the extended display according to their needs to obtain the best operating experience in different scenarios. In scenarios where frequent angle adjustments are required, the damping force can be reduced to make adjustments easier; in scenarios where a fixed angle is required, the damping force can be increased to ensure the stability of the display.

[0049] like Figure 1C As shown, the back of the bracket body 11 is also provided with a receiving groove 16 corresponding in position and shape to the expansion connector 12. The receiving groove 16 is used to accommodate the expansion connector 12 in the folded position. This design allows the expansion display module to be stored more compactly when not in use, making it easier to carry.

[0050] The interior of the receiving groove 16 is designed to precisely match the shape of the expansion connector 12, and is usually manufactured using a mold one-step molding process to ensure accurate dimensions. A layer of velvet or soft material can also be attached to the interior of the receiving groove 16 to prevent the connector from being worn during storage.

[0051] The presence of storage slot 16 greatly facilitates the user's need to store the extended display 2 when not in use. For example, when working outside, the user can easily fold the extended display 2 and store it in storage slot 16, reducing the burden of carrying. The storage slot is designed not only for compactness, but also for consistency in appearance with the stand body 11, making the entire device more aesthetically pleasing and harmonious when stored.

[0052] Specifically, the design of the receiving groove 16 must take into account the precise dimensions of the expansion connector 12 to ensure a snug fit. During the manufacturing process, high-precision molds and processing techniques are required to ensure that the size and shape of the receiving groove meet the design requirements. Furthermore, the velvet or soft material inside the receiving groove must also possess good wear and pressure resistance to prevent the expansion connector from wearing out during long-term use.

[0053] Figure 1E 、 Figure 4A and Figure 4B This embodiment shows a stand body 11 equipped with a telescopic mechanism 17. This mechanism, comprising a telescopic guide rail 171 and an elastic member 172, is designed to accommodate laptop screens of varying sizes. This mechanism allows the user to adjust the width of the extended stand body 1 as needed, ensuring a perfect fit between the extended display 2 and the laptop screen.

[0054] Telescopic rail 171 is designed as a multi-section, overlapping structure that can be extended or shortened as needed. Each section is connected by sliding bearings to ensure smooth telescopic movement. Elastic component 172, typically a coil spring or compression spring, is installed at the end of the rail. When the rail is extended, the spring provides a reset force, ensuring that the rail automatically returns to its initial position.

[0055] The Telescopic Mechanism 17 addresses the varying sizes of laptop screens. Whether you're looking at a 13-inch portable or a 15-inch professional notebook, the Telescopic Mechanism 17 provides a perfect fit. The multi-section design of the guide rail ensures a smooth transition between maximum and minimum sizes, while the elastic components ensure stability and security during use.

[0056] Specifically, the multi-section overlapping design of telescopic rail 171 requires consideration of its structural strength and rigidity to ensure it does not deform or loosen during extension and retraction. The selection of sliding bearings is also crucial; high-quality sliding bearings can significantly reduce friction and ensure smooth extension and retraction of the rail. Elastic component 172 must possess excellent elasticity and durability to ensure stable performance during long-term use.

[0057] like Figure 1A As shown, clamping parts 18 are also provided on both sides of the front of the bracket body 11 for clamping the two side edges of the notebook computer display screen. These clamping parts 18 can provide additional stability to prevent the extended display module from sliding or shifting during use.

[0058] The clamping member 18 is typically made of high-strength plastic or metal, and has a non-slip rubber pad attached to the portion that contacts the display screen. This provides a secure clamping force without damaging the display screen surface. The clamping member 18 can also be designed to be adjustable so that the user can adjust it according to the thickness of the display screen.

[0059] The clamping member 18 is cleverly designed to provide a secure hold without damaging the laptop display. This allows users to move the device without worrying about the stability of the extended display module. The clamping member's adjustment mechanism, typically through rotation or sliding, allows users to easily adjust its position to accommodate displays of varying thicknesses.

[0060] In actual use, the anti-slip rubber pads on the clamping member 18 effectively prevent the display from sliding while also protecting the edges of the display from damage. This design not only ensures stability but also improves safety and reliability. Users can adjust the position of the clamping member to ensure a secure grip based on the thickness of the display.

[0061] Figure 4A and Figure 4BThe back of the bracket body 11 is provided with a support member 19, which is rotatably connected to the bracket body 11 and is used to support the laptop display on a flat surface. The design of the support member 19 ensures the stability and practicality of the extended display module in various working environments.

[0062] The support member 19 is generally foldable and can be unfolded to form a stable support structure when in use and folded and stored when not in use. The rotation connection of the support member 19 is generally a shaft or hinge structure to ensure smooth operation during the unfolding and folding process.

[0063] The support member 19 can not only provide stable support on a desktop, but can also be used outdoors or on uneven surfaces, meeting the needs of users in various environments. The design of the support member takes portability and stability into consideration. When unfolded, it can provide sufficient support force, and when folded, it is easy to carry and store.

[0064] In practical applications, the design of the support component 19 needs to consider its stability on various surfaces. For example, on uneven outdoor surfaces, the support component needs to have sufficient adjustment capabilities to ensure the stability of the extended display module. Furthermore, the material selection of the support component also needs to consider its weather resistance and durability to ensure long-term use in various environments.

[0065] like Figure 3A and Figure 3B As shown, at least one side edge of the extended display 2 is an inwardly recessed edge 22, and the connecting slot 21 is disposed within the inwardly recessed edge 22. This design helps to compactly store the extended display 2 in the bracket body 11 when not in use, thereby reducing space occupation.

[0066] The inwardly recessed edge 22 is typically manufactured using precision CNC machining techniques to ensure accuracy of size and shape. A dust cover may also be provided inside the connecting chute 21 to cover the chute when the extended display 2 is not in use, preventing dust and debris from entering.

[0067] This design not only maximizes physical space utilization but also provides an aesthetically pleasing appearance, making the entire extended display module appear more concise and modern. The inward-facing recessed design also enhances the structural strength of the chute, improving its durability during use.

[0068] Specifically, the inwardly recessed design must take into account the machining accuracy and strength of the chute 21. During the manufacturing process, high-precision CNC machining technology is required to ensure the precise size and shape. Furthermore, the dust cover inside the chute must be well sealed and durable to prevent dust and debris from entering the chute and affecting its normal operation.

[0069] Figure 1D 、 Figure 2A 、 Figure 2B 、 Figure 3A and Figure 3B The structure of the expansion connector 12 connected to the expansion display 2 is shown. The connecting rail 13 slides from the opening of the connecting slot 21 to the end of the connecting slot 21. A limit member 23 is provided at the end of the connecting slot 21 to block the connecting rail 13 and prevent the expansion display 2 from falling off during use.

[0070] The stopper 23 is typically made of metal or high-strength plastic and may contain a spring structure. When the connecting rail 13 slides into place, the stopper 23 automatically pops out, preventing the rail from sliding further. The design of the stopper 23 ensures the safety of the extended display during use, even during frequent movement or adjustments.

[0071] The stopper 23 not only provides mechanical safety but also, through its sophisticated structural design, ensures smooth and reliable use of the extended display 2. The stopper's spring structure automatically adapts to changes in the rail's position, providing a stable stop and preventing the rail from accidentally sliding out during use.

[0072] In practical applications, the design of the position-limiting component 23 must consider its reliability under various operating conditions. For example, when frequently moving and adjusting the display angle, the position-limiting component must be durable and stable. Furthermore, the material selection and machining accuracy of the position-limiting component are crucial to ensure its stable performance over extended periods of use.

[0073] Existing expansion display modules are mostly standalone displays that require additional brackets or connectors for installation, which is cumbersome and lacks stability. The present invention integrates the expansion connector with the bracket body, simplifying installation and improving stability. Furthermore, the present invention incorporates a dual-axis hinge and damping mechanism, making the display more flexible and secure during use.

[0074] For example, existing extended monitors on the market usually require separate desktop stands or clamps to secure them, requiring users to purchase these accessories and spend time installing and adjusting them. However, the design of this utility model simplifies this process, allowing users to simply slide the extended monitor into the slot for easy installation.

[0075] Traditional extended displays often require additional power and data cables, increasing user complexity and desktop clutter. The expanded display module of this utility model achieves an integrated connection between the display and the bracket through optimized design, simplifying the use of connecting cables and improving the user experience.

[0076] Many traditional extended displays require connection via HDMI, USB, or dedicated interfaces. These connection methods not only require multiple interfaces but also increase cable clutter. The present invention can be designed to achieve power supply and data transmission through a unified interface such as USB-C, greatly simplifying the connection process.

[0077] The detailed description of the above specific implementation methods demonstrates the numerous advantages of this utility model in terms of structural design and user experience. The expandable display module not only provides an efficient and convenient expansion display solution, but also ensures safety and stability during use through its innovative mechanical design. Whether used for daily office work, professional design, or outdoor display, this utility model provides an excellent user experience.

[0078] The application of the utility model in the field of extended display technology fully reflects the pursuit of portability, ease of use and high efficiency by modern technology, and provides users with an ideal multi-display solution.

[0079] In practical applications, the design and implementation of an extended display module must consider not only its basic functionality but also user experience and product reliability. For example, when designing an extended display module, it's necessary to consider user needs in different usage scenarios and optimize the design to meet these needs. Furthermore, it's crucial to ensure product stability and durability over extended periods of use to enhance user satisfaction and market competitiveness.

[0080] To achieve these goals, the design team conducted in-depth research on existing technologies and market demands, incorporating advanced technologies and materials into the product design. For example, when selecting materials for rails and chutes, they considered using high-strength alloys to improve durability and load-bearing capacity. When designing biaxial hinges, they incorporated high-precision machining and high-quality bearings to ensure stable performance over long-term use.

[0081] At the same time, it's also important to consider product usability and user experience. For example, when designing a telescopic mechanism, consider incorporating intelligent adjustment features to allow users to more conveniently adjust the width of the extension bracket. When designing a damping mechanism, consider incorporating a convenient and easy-to-use adjustment mechanism to allow users to flexibly adjust the damping force based on different usage scenarios.

[0082] In short, this utility model, through its innovative design and advanced technology, provides users with an efficient and convenient extended display solution. Whether used in daily office work, professional design, or outdoor exhibitions, the extended display module delivers an excellent user experience and reliable performance. By continuously optimizing its design and improving product quality, this utility model will continue to lead the way in extended display technology, bringing even more convenience and value to users.
