Description

Technical Field

[0001] This invention relates to the field of foldable screen device technology, and in particular to a foldable screen electronic device. Background Technology

[0002] In recent years, flexible foldable screen technology has made significant progress in the field of mobile terminals and is gradually extending to electronic devices such as laptops. These devices, by introducing foldable OLEDs or similar flexible display panels, aim to balance large-screen display with portability, providing users with a more flexible form factor.

[0003] Currently, some foldable laptops use virtual keyboards instead of physical keyboards, resulting in low input efficiency, high accidental touch rates, and a lack of key feedback, impacting user experience. While some products retain physical keyboards to improve the user's input experience, integrating a keyboard can lead to an excessively large folded size when the screen is large, significantly reducing portability. Conversely, prioritizing a compact folded design often requires compressing the screen display area, affecting the user's viewing experience.

[0004] It is evident that balancing the portability of the device with the display effect is a problem that needs to be solved by those skilled in the art. Summary of the Invention

[0005] The purpose of this invention is to provide a foldable screen electronic device that can effectively reduce the overall size after folding while ensuring that the screen size is not compressed, thus significantly improving portability.

[0006] To address the aforementioned technical problems, embodiments of the present invention provide a foldable screen electronic device, comprising:

[0007] A flexible folding screen includes a first display screen and a second display screen that rotate relative to each other, wherein the area of ​​the second display screen is larger than that of the first display screen, and the flexible folding screen has a closed state in which the first display screen and the second display screen are attached together;

[0008] The host is rotatably connected to the side of the first display screen away from the second display screen. The host integrates an operation panel, and in the closed state, the host and the first display screen are projected together within the range of the second display screen.

[0009] In some embodiments, in the closed state, the back of the first display screen and the back of the second display screen are in contact with each other, or the front of the first display screen and the front of the second display screen are in contact with each other.

[0010] In some embodiments, including:

[0011] A first pivot portion connects the first display screen and the second display screen, so that the two are coplanar in the unfolded state;

[0012] The second pivot unit connects the main unit and the first display screen, allowing the main unit to rotate relative to the first display screen within an opening angle range of 0° to 360°.

[0013] The pivot axes of the first pivot section and the second pivot section are parallel.

[0014] In some embodiments, at least one of the first pivot and the second pivot includes a damping component to provide hovering at any angle during relative rotation of the two correspondingly connected components.

[0015] In some embodiments, a support is provided on the back of the first display screen, one end of which is rotatably connected to the first display screen, so that the support can switch between an embedded state and an open state;

[0016] In the embedded state, the bracket is housed in a receiving groove on the back of the first display screen;

[0017] In the open state, the other end of the bracket rotates out of the receiving slot to support the flexible folding screen in an inclined use posture.

[0018] In some embodiments, the bracket is a telescopic bracket, the inner wall of the receiving groove is provided with a positioning bead, and the end of the bracket connected to the first display screen is provided with a positioning groove. When the bracket is in the open state and / or the embedded state, the positioning bead engages with the positioning groove to restrict the rotational freedom of the bracket relative to the first display screen.

[0019] In some embodiments, in the closed state, the first display screen, the second display screen, and the host are aligned along the short side;

[0020] The ratio of the shorter side of the first display screen to the shorter side of the second display screen is between 1:1.5 and 1:2.5, and the sum of the shorter side length of the host and the shorter side length of the first display screen is equal to the shorter side length of the second display screen.

[0021] In some embodiments, the flexible folding screen is an integrated flexible display screen, wherein the first display screen and the second display screen are two adjacent display areas on the flexible display screen that can be bent relative to each other; or...

[0022] The flexible folding screen is a split flexible display screen, in which the first display screen and the second display screen are relatively independent, and the two are rotatably connected by a first pivot.

[0023] In some embodiments, the host includes a housing, and the operation panel is located on the front of the housing. The operation panel includes a keyboard and a touchpad, and the top of the keys of the keyboard and the upper surface of the touchpad do not extend beyond the surface of the housing.

[0024] In some embodiments, the front and / or back of the housing have flat support planes.

[0025] The beneficial effect of this application is that by combining the larger second display screen with the smaller first display screen to form a flexible folding screen, the screen size of the flexible folding screen is effectively guaranteed; and by rotating the host with the integrated operation panel to the back of the first display screen, the projection of the host and the first display screen both fall within the range of the second display screen when the whole machine is closed, and the size of the whole machine is reduced to the size of the second display screen, which achieves a significant reduction in the volume of the whole machine after folding, thereby greatly improving the overall portability of the device.

[0046] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present invention.

[0047] The terms "comprising" and "having," and any variations thereof, in the specification and accompanying drawings of this invention are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the steps or units listed, but may include steps or units not listed.

[0048] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0049] Next, we will describe in detail a foldable screen electronic device provided by the embodiments of the present invention, which is particularly suitable for portable computing terminals, such as laptops and tablets. Figure 1 This is a front view of a foldable screen electronic device according to an embodiment of the present invention. The device includes a flexible foldable screen 1 and a host 2. The flexible foldable screen 1 includes a first display screen 11 and a second display screen 12, which are rotatably connected, allowing the flexible foldable screen 1 to switch between an unfolded state and a closed state. The area of ​​the second display screen 12 is larger than that of the first display screen 11, thus achieving an asymmetrical design of the two displays.

[0050] In the unfolded state, the first display screen 11 and the second display screen 12 are superimposed in the length or width direction to form a flexible folding screen 1 with a large overall size, which effectively ensures the screen size of the flexible folding screen 1; in the closed state, the first display screen 11 and the second display screen 12 are attached to each other to form a display unit with superimposed thickness but whose outer contour is dominated by the larger one (the second display screen 12), which effectively reduces the size of the whole machine after folding.

[0051] The main unit 2 is rotatably connected to the side of the first display screen 11 away from the second display screen 12. When the whole machine needs to be folded, the main unit 2 flips together with the first display screen 11 and is eventually stored in the projection area covered by the second display screen 12, so that the main unit 2 will not affect the overall size of the whole machine after flipping.

[0052] Furthermore, when the flexible folding screen 1 is in the closed state, the main unit 2 can fall into the projection area of ​​the first display screen 11 or the projection area of ​​the second display screen 12 by rotating. When the main unit 2 falls into the projection area of ​​the first display screen 11, the thickness of the entire device after folding is the sum of the thicknesses of the first display screen 11, the second display screen 12, and the main unit 2; when the main unit 2 falls into the projection area of ​​the second display screen 12, the thickness of the entire device after folding is the sum of the thicknesses of the second display screen 12 and the first display screen 11, or the sum of the thicknesses of the second display screen 12 and the main unit 2. However, regardless of the folding method, the size of the second display screen 12 as the outer contour size of the entire device after folding does not affect the overall dimensions.

[0053] In summary, this application combines the larger second display screen 12 with the smaller first display screen 11 to form a flexible folding screen 1, effectively ensuring the screen size of the flexible folding screen 1; and the host 2, which integrates the operation panel, is rotatably connected to the back of the first display screen 11, so that when the whole machine is closed, the projections of the host 2 and the first display screen 11 fall within the range of the second display screen 12, and the size of the whole machine is reduced to the size of the second display screen 12, achieving a significant reduction in the volume of the whole machine after folding, thereby greatly improving the overall portability of the device.

[0054] In the closed state, the back of the first display screen 11 and the back of the second display screen 12 are attached to each other. In this mode, the display surfaces of both displays face outwards. The advantage of this method is that even in the closed state, the user can still selectively use either display screen as a display window, which improves the flexibility of device interaction.

[0055] In some embodiments, when the flexible folding screen 1 is closed, the front of the first display screen 11 and the front of the second display screen 12 may be fitted together, such as... Figures 4 to 6 As shown, in this mode, the display surfaces of the two displays are in contact with each other or nearly in contact, and a flexible buffer layer is usually required on the contact surfaces to prevent scratches.

[0056] It should be noted that in this embodiment, the front side refers to the side of the flexible folding screen 1 that has a display area, and the back side is the side opposite to the front side. As for the front side of the host 2, it refers to the side facing the user or located on the same side as the display area of ​​the flexible folding screen 1 when the host 2 is parallel or coplanar with the flexible folding screen 1, and the back side of the host 2 is the side opposite to its front side.

[0057] Of course, the flexible folding screen 1 can also switch between the two closed states mentioned above. That is, in one closed state, the flexible folding screen 1 gradually unfolds by rotating the first display screen 11 and the second display screen 12 relative to each other, and reaches a fully unfolded state when the first display screen 11 and the second display screen 12 are coplanar. Figure 2 and Figure 3 As shown, with the continuous rotation of the first display screen 11 relative to the second display screen 12, the first display screen 11 and the second display screen 12 gradually switch from a fully open state to another closed state.

[0058] The device includes a first pivot 3 and a second pivot 4. The first pivot 3 connects the first display screen 11 and the second display screen 12, ensuring stable rotation of both and enabling switching between at least the unfolded and closed states. Furthermore, the first pivot 3 allows the first display screen 11 and the second display screen 12 to be coplanar in the unfolded state, thereby enabling the flexible folding screen 1 to achieve a large display area. Coplanarity here means that the display planes of the first display screen 11 and the second display screen 12 lie in the same plane.

[0059] The second pivot 4 is used to connect the main unit 2 and the first display screen 11, so that the main unit 2 can rotate freely within a full angular range of 0° to 360° relative to the first display screen 11. Specifically, the main unit 2 can be flipped backward (or outward) so that its back side is in contact with the back side of the first display screen 11, can be flipped forward (or inward) so that its front side is coplanar with the front side of the first display screen 11, and can continue to be flipped forward so that its front side is in contact with the front side of the first display screen 11.

[0060] It should be noted that the pivot axes of the first pivot part 3 and the second pivot part 4 should be set in parallel to ensure that the relative motion trajectories between the components are coordinated and consistent under any unfolded or folded posture, and to avoid structural interference or stress concentration caused by axis misalignment.

[0061] In some embodiments, the first pivot 3 and the second pivot 4 may employ a hinge, a teardrop-shaped bending structure, or a flexible rotating shaft to ensure a stable screen bending radius and uniform stress distribution during repeated opening and closing, preventing creases or breakage. Furthermore, at least one of the first pivot 3 and the second pivot 4 includes a damping component, which may be implemented using friction pads, hydraulic buffers, or other technologies. When the user adjusts the opening angle of the two displays or the rotation position of the host 2, the damping component provides continuous and controllable resistance during relative rotation, allowing the two connected components to reliably hover at any intermediate angle.

[0062] This application utilizes an asymmetrical design with two displays, along with the rotation adjustment of the main unit 2, to allow the device to freely switch between multiple working modes. The specific modes and application scenarios are as follows:

[0063] Laptop scenario: With the first display screen 11, the second display screen 12, and the host 2 coplanar, the device is fully open. At this time, keeping the first pivot 3 stationary, the host 2 rotates inward by a certain angle under the action of the second pivot 4, such as... Figure 7 and Figure 8 As shown, the angle between the front of the host 2 and the front of the flexible folding screen 1 is an obtuse angle. When in use, the host 2 is used as the main support component, and the whole machine is L-shaped or approximately L-shaped.

[0064] In laptop usage scenarios, the second pivot 4 allows users to adjust the angle of the flexible folding screen 1 as needed. The main unit 2 integrates an operation panel. Unlike existing solutions that rely entirely on magnetically attached keyboards or virtual keyboards, this ensures that users can still enjoy the comfortable and stable typing feel and precise touch experience of a traditional laptop in laptop mode. It completely avoids the problems of magnetic keyboards being easily lost, requiring separate charging, having unstable connections, and potentially scratching the screen. It retains the comfortable typing feel of a traditional laptop while avoiding the various drawbacks of magnetic keyboards, balancing large-screen portability with keyboard input.

[0065] In addition, a bracket 5 is provided on the back of the first display screen 11. One end of the bracket 5 is rotatably connected to the first display screen 11 via a pivot, and the other end is a free support end. The bracket 5 can switch between two states:

[0066] In the embedded state, the bracket 5 is completely housed in the pre-set receiving groove on the back of the first display screen 11, with its surface flush with or lower than the back of the first display screen 11, without affecting the flatness and aesthetics of the device after it is closed.

[0067] In the open state, the bracket 5 rotates around the pivot to extend into the receiving slot, with its free end abutting against the placement plane. Together with the flexible foldable screen 1 in a laptop scenario, it supports the entire flexible foldable screen 1 at a certain tilt angle, facilitating user viewing or touch operation. By providing stable support for the flexible foldable screen 1 through the bracket 5, the "top-heavy" problem that may occur with asymmetrical structures is solved, improving the reliability of use in complex configurations and generally meeting the input needs of regular office work.

[0068] Tablet PC Scenario: With the first display screen 11, the second display screen 12, and the main unit 2 coplanar, the device is fully opened, the stand 5 is embedded in the receiving slot, and the main unit 2 rotates backward (or outward) under the action of the second pivot 4 until it is in contact with the back of the first display screen 11. At this time, only the first display screen 11 and the second display screen 12 are coplanar, and the device enters tablet PC usage mode. The display screens support touch functionality, so the entire device can be used like a tablet PC. Figure 9 and Figure 10As shown. Furthermore, in tablet mode, the overall size of the device is the sum of the sizes of the first display screen 11 and the second display screen 12, which reduces the size of the main unit 2 by at least. Therefore, holding the device in tablet mode will not affect the user experience in terms of overall size.

[0069] Large screen display scenario: When the first display screen 11, the second display screen 12, and the host 2 are coplanar, the device is fully opened. Under the action of the second pivot 4, the host 2 rotates backward (or outward) at a certain angle, so that the back of the host 2 forms an acute angle with the back of the flexible folding screen 1. At this time, the host 2 can serve as the bottom support structure of the entire device, allowing the flexible folding screen 1 to stand upright, such as... Figure 11 and Figure 12 As shown. At this time, the laptop enters the large screen display mode. In this mode, when viewed from the front, the size of the whole machine is comparable to that of the flexible folding screen 1. Users can see the entire display area of ​​the flexible folding screen 1, providing users with an excellent display experience. When viewed from the side, because the main unit 2 is designed to be narrow, the whole machine occupies less space in this mode, which can meet the needs of normal use in environments with limited space.

[0070] In this mode, when watching videos or presentations, the narrow main unit 2 serves as a base, allowing the entire device to stand on the desktop with a small projection area. Compared to traditional laptops, it doesn't require a large footprint, making this mode particularly advantageous in space-constrained environments such as cafes or airplane tray tables.

[0071] Two-person face-to-face interaction scenario: With the first display screen 11, the second display screen 12, and the main unit 2 coplanar, the device is fully open. The first display screen 11 rotates a certain angle relative to the second display screen 12 via the first pivot 3, while the second pivot 4 itself does not rotate. The main unit 2 moves synchronously with the first display screen 11. At this time, the main unit 2 and the first display screen 11 are coplanar, forming an inverted V-shaped tent structure. Please refer to [reference needed]. Figure 13 and Figure 14 As shown. The back of the second display screen 12 forms an acute angle with the back of the first display screen 11 and the main unit 2, and the sides of the second display screen 12 and the main unit 2 serve as support structures that contact the placement plane.

[0072] The first person can use the first display screen 11, and the second person can use the second display screen 12, which meets the needs of users for face-to-face communication, collaborative work, and two-person gaming entertainment, demonstrating the product's multi-scenario adaptability.

[0073] Dual-sided use scenario in narrow space: In the above-mentioned two-person face-to-face interaction scenario mode, the first display screen 11 and the host 2 continue to rotate backward around the pivot axis of the first pivot part 3 until they are attached to the back of the second display screen 12, forming a folded mode of the whole machine.

[0074] In this folding mode, the overall size of the device is reduced by half compared to its fully unfolded state. This design can meet the needs of use in confined spaces, while also showcasing the device's playability and entertainment value. Figure 15 and Figure 16 As shown, users can choose to use either the side with the main unit 2 and the first display screen 11, or the other side with only the second display screen 12, depending on their individual needs. Whether for work or entertainment, this mode of the entire machine can meet the requirements. The dual-sided usage in narrow spaces also demonstrates the multi-scenario adaptability of this solution design.

[0075] Based on the aforementioned bracket 5, bracket 5 adopts a telescopic structure, that is, its length can be adjusted within a certain range to adapt to different usage height requirements.

[0076] To ensure the stability of the bracket 5 in both the open and recessed states, a positioning bead is provided on the inner wall of the receiving groove. The positioning bead has a spring and a ball bearing, and a positioning groove is provided at the end of the bracket 5 that connects to the first display screen 11. When the bracket 5 is fully rotated out and opened into place, the positioning bead engages with the positioning groove under the action of the spring, forming a mechanical limit, effectively restricting the rotational freedom of the bracket 5 relative to the first display screen 11, and preventing it from accidentally retracting or shaking during use.

[0077] Users can push the bracket 5 with external force to make the positioning groove push the positioning bead back until the positioning bead is disengaged from the positioning groove, thus enabling the bracket 5 to be quickly folded.

[0078] In some embodiments, when the flexible folding screen 1 is closed, the first display screen 11, the second display screen 12, and the host 2 are aligned along the short side to form a neat rectangular outline, which is convenient for putting into a bag or stacking for storage.

[0079] Furthermore, the short side lengths of the first display screen 11 and the second display screen 12 are set to a specific ratio range, such as between 1:1.5 and 1:2.5. The short side length of the host 2 is exactly equal to the short side length of the first display screen 11. This ensures that when the host 2 and the first display screen 11 are flipped together to the back of the second display screen 12, the edges of the three are perfectly aligned without any protrusions or depressions, maximizing the use of the projection area of ​​the second display screen 12 for storage.

[0080] Preferably, the ratio of the short side lengths of the first display screen 11 to the second display screen 12 is 1:2, meaning the first pivot 3 is located at 1 / 3 of the short side of the flexible folding screen 1, dividing the flexible folding screen 1 into the first display screen 11 and the second display screen 12. Correspondingly, the short side length of the host 2 is the same as the short side length of the first display screen 11, thus creating a 3:1 ratio between the flexible folding screen 1 and the host 2. When the device is folded, the first display screen 11 and the host 2 are attached to the back of the second display screen 12 and overlap with the projection area of ​​the second display screen 12, thereby reducing the volume to less than 1 / 2 of its unfolded state.

[0081] When fully unfolded, the flexible folding screen 1 occupies 3 / 4 of the total area of ​​the device, providing a sufficiently large display area; while the main unit 2 occupies 1 / 4 of the total area, without excessively compressing the display area of ​​the flexible folding screen 1.

[0082] In some embodiments, the flexible foldable screen 1 is an integrated flexible display screen, that is, the entire flexible OLED or panel is divided into adjacent first display areas and second display areas, which are connected by a first pivot 3. This solution has the advantages of good display continuity and good visual effect, and is suitable for scenarios with high requirements for screen integrity.

[0083] In other embodiments, the flexible folding screen 1 can also be a split flexible display screen, that is, the first display screen 11 and the second display screen 12 are two independent flexible display modules, which are mechanically and electrically connected through the first pivot part 3. The advantage of this solution is that damaged screens can be replaced independently, reducing the risk of low yield of a single large screen.

[0084] The host 2 includes a housing, and an operation panel is integrated on the front of the housing. The operation panel includes at least a keyboard 21 and a touchpad 22, with the touchpad 22 located to the right of the keyboard 21. The tops of the keys on the keyboard 21 and the upper surface of the touchpad 22 do not extend beyond the surface contour of the housing. In other words, the operating elements of the operation panel are embedded within the housing, giving the front of the housing a flat surface.

[0085] In the closed state (the front of the host 2 is in contact with the front of the first display screen 11), since the front of the housing has a flat surface, the protruding operating elements will not squeeze the front of the first display screen 11, thus avoiding damage to the first display screen 11.

[0086] Furthermore, the front and / or back of the casing have flat supporting surfaces, allowing the back and front of the host 2 to be stably placed on a supporting object in both laptop and large-screen display scenarios. Simultaneously, in tablet scenarios, the back of the host 2 can be fitted against the back of the first display screen 11, achieving a tablet-like visual appearance.
