Abstract
Description
Technical Field
[0001] This disclosure relates to the field of electronic device technology, and more particularly to a dual-screen lifting structure and electronic device. Background Technology
[0002] Currently, as AI (artificial intelligence) interactive chat modes mature, vertical browsing and dual-screen interaction scenarios are becoming increasingly common. However, on laptops with a typical 16:9 aspect ratio, this user experience struggles to meet the demands of continuously inputting commands and comparing interactive content vertically during AI interaction, leading to inconvenience for users. Furthermore, to ensure the original work interface remains unaffected, users typically place the AI interactive interface on either side of the laptop screen, reducing the window ratio and making reading even more difficult, thus impacting the original work interface size. To address this issue, existing solutions integrate a flexible screen with a motor to achieve a vertical screen effect; however, the high cost of the motor and flexible screen increases production costs, and the time required for the motor to roll the flexible screen into vertical mode is too long, hindering rapid transitions. Utility Model Content

[0005] A dual-axis hinge, with two rotating ends connected to the first screen assembly and the second screen assembly respectively, is used to drive the first screen assembly and the second screen assembly to unfold or fold.
[0006] A single-axis hinge, which is disposed opposite to the dual-axis hinge and connected to the second screen assembly and the system end, is used to drive the second screen assembly to rotate relative to the system end;
[0007] A transmission component is connected to the dual-axis hinge and the single-axis hinge; when the dual-axis hinge drives the first screen assembly and the second screen assembly to unfold or fold, the transmission component can synchronously drive the single-axis hinge to rotate, so that the second screen assembly drives the first screen assembly to lift or fall in the vertical direction.
[0008] In one embodiment, the dual-axis hinge includes a first axis, a second axis, a first connecting component, and a second connecting component. The first axis and the second axis are driven by a gear set. The first connecting component is mounted on the first axis and fixedly connected to the first screen assembly. The second connecting component is mounted on the second axis and fixedly connected to the second screen assembly.
[0009] In one embodiment, the gear set includes:
[0010] The first shaft gear is coaxially mounted on the first shaft;
[0011] The second shaft gear is coaxially mounted on the second shaft;
[0012] The transition gear set is meshed between the first shaft gear and the second shaft gear.
[0013] In one embodiment, the biaxial hinge further includes:
[0014] The first slide rail limiting member has a first end connected to the first shaft gear and a second end slidably connected to the first connecting component, which is used to limit the flip angle of the first screen assembly.
[0015] The second slide rail limiting member has a first end connected to the second shaft gear and a second end slidably connected to the second connecting component, which is used to limit the flip angle of the second screen assembly.
[0016] In one embodiment, the second end of the first sliding groove limiting member and the second end of the second sliding groove limiting member are both configured as sliding holes, and limiting shafts are provided on the first connecting member and the second connecting member, with the sliding holes correspondingly slidably connected to the limiting shafts.
[0017] In one possible embodiment, the first slide groove limiting member and the first shaft gear are constructed as a single unit;
[0018] The second sliding groove limiting component and the second shaft gear are constructed as a single unit.
[0019] In one possible implementation, the transmission assembly includes:
[0020] The first gear is coaxially mounted on the second shaft.
[0021] The second gear is coaxially mounted on the shaft of the single-shaft hinge, and the second gear is connected to the first gear via a chain drive; wherein the rotation angle ratio of the gear set, the first gear and the second gear is 1.5:1.5:1.
[0022] Secondly, this application provides an electronic device, including a first screen assembly, a second screen assembly, and a system terminal, and also includes a dual-screen lifting structure in any of the above-described possible embodiments.
[0023] In one embodiment, the first screen assembly includes a first screen and a first screen housing for mounting the first screen, wherein the first screen housing is fixedly connected to a first connecting component of the dual-screen lifting structure.
[0024] The second screen assembly includes a second screen and a second screen housing for mounting the second screen, the second screen housing being fixedly connected to the second connecting component of the dual-screen lifting structure.
[0025] In one embodiment, the system has a housing with a cavity formed thereon for accommodating the second screen assembly, the second screen assembly being connected to the cavity via the single pivot hinge.
[0026] Compared with existing technologies, the advantages of this application are as follows: The dual-screen lifting structure provided in this application, by setting up a dual-axis hinge, a single-axis hinge, and a transmission component, allows the single-axis hinge to rotate synchronously via the transmission component when the dual-axis hinge drives the first and second screen components to unfold. This causes the second screen component to rotate relative to the system end, thereby lifting the second and first screen components vertically. This not only unfolds the first and second screen components but also increases their height relative to the system end, increasing the user's viewing range on both screens and providing a wider field of view. Furthermore, this application achieves both screen unfolding and lifting through a single dual-screen lifting structure, which is simple in structure and reduces production costs.

[0041] 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.
[0042] Firstly, such as Figure 1-4 As shown, this application provides a dual-screen lift structure 1, applied to an electronic device 2. The electronic device 2 includes a first screen assembly 21, a second screen assembly 22, and a system terminal 23. The dual-screen lift structure 1 includes:
[0043] The dual-axis hinge 11 has two rotating ends connected to the first screen assembly 21 and the second screen assembly 22 respectively, and is used to drive the first screen assembly 21 and the second screen assembly 22 to unfold or fold.
[0044] A single-axis hinge 12 is disposed opposite to the dual-axis hinge 11 and connected to the second screen assembly 22 and the system terminal 23, for driving the second screen assembly 22 to rotate relative to the system terminal 23.
[0045] The transmission component 13 is connected to the dual-axis hinge 11 and the single-axis hinge 12. When the dual-axis hinge 11 drives the first screen component 21 and the second screen component 22 to unfold or fold, the transmission component 13 can synchronously drive the single-axis hinge 12 to rotate, so that the second screen component 22 drives the first screen component 21 to rise or fall in the vertical direction.
[0046] This application provides a dual-screen lifting structure 1. By setting a dual-axis hinge 11, a single-axis hinge 12, and a transmission component 13, when the dual-axis hinge 11 drives the first screen assembly 21 and the second screen assembly 22 to unfold, the transmission component 13 can synchronously drive the single-axis hinge 12 to rotate, causing the second screen assembly 22 to rotate relative to the system end 23. This causes the second screen assembly 22 and the first screen assembly 21 to be lifted vertically, thereby completing the unfolding of the first screen assembly 21 and the second screen assembly 22 while also raising their height relative to the system end 23, increasing the screen range for the user to view the first screen assembly and the second screen assembly, and allowing the user to enjoy a wider field of view.
[0047] This application, by simply setting up a dual-screen lifting structure 1, enables the first screen component 21 and the second screen component 22 to be unfolded while simultaneously increasing their height, facilitating AI chat interaction for users. The dual-screen setup allows users to place the interactive interface on one screen component during AI chat interaction without affecting the use of the other screen, thus meeting the user's need for simultaneous AI chat interaction and other work interfaces. Furthermore, the simple structure of this dual-screen lifting structure reduces production costs.
[0048] In one possible implementation, such as Figure 6-8As shown, the dual-axis hinge 11 includes a first shaft 111, a second shaft 112, a first connecting component 113, and a second connecting component 114. The first shaft 111 and the second shaft 112 are driven by a gear set 115. The first connecting component 113 is mounted on the first shaft 111 and fixedly connected to the first screen assembly 21. The second connecting component 114 is mounted on the second shaft 112 and fixedly connected to the second screen assembly 22.
[0049] For example, such as Figure 5 As shown, the first screen assembly 21 includes a first screen 211 and a first screen housing 212 for mounting the first screen, and the first screen housing 212 is fixedly connected to the first connecting member 113.
[0050] The second screen assembly 22 includes a second screen 221 and a second screen housing 222 for mounting the second screen, the second screen housing 222 being fixedly connected to the second connecting member 114. Thus, when the first screen assembly 21 is opened, the first and second axes of the dual-axis hinge can be rotated, thereby causing the first screen assembly 21 and the second screen assembly 22 to flip open.
[0051] For example, such as Figure 6-8 As shown, due to the gear set 115, the first shaft 111 and the second shaft 112 are rotated and opened synchronously, and the first screen assembly 21 and the second screen assembly 22 are opened synchronously. Thus, when the included angle between the first screen assembly 21 and the second screen assembly 22 is 180 degrees, the first shaft 111 and the second shaft 112 each rotate 90 degrees. At this time, the first screen 211 of the first screen assembly and the second screen 221 of the second screen assembly are in the same plane.
[0052] For example, such as Figure 9 As shown, the gear set 115 includes:
[0053] The first shaft gear 1151 is coaxially mounted on the first shaft 111;
[0054] The second shaft gear 1152 is coaxially mounted on the second shaft 112;
[0055] The transition gear set 1153 is meshed between the first shaft gear 1151 and the second shaft gear 1152.
[0056] like Figure 9 As shown, the first shaft gear 1151 is coaxially mounted on the first shaft 111 and can rotate synchronously with the first shaft 111. The second shaft gear 1152 is coaxially mounted on the second shaft 112 and can rotate synchronously with the second shaft 112.
[0057] The transition gear set 1153 includes a first transition gear and a second transition gear. The first shaft gear 1151, the first transition gear, the second transition gear, and the second shaft gear 1152 are sequentially meshed together. The rotation angles of the first shaft gear 1151, the transition gear set 1153, and the second shaft gear 1152 are the same. For example, when the first shaft gear 1151 rotates at 90 degrees, the rotation angle of the second shaft gear 1152 is also 90 degrees, resulting in an angle of 180 degrees between the first screen assembly 21 and the second screen assembly 22. For example, when the first shaft gear 1151 rotates at 60 degrees, the rotation angle of the second shaft gear 1152 is also 60 degrees, resulting in an angle of 120 degrees between the first screen assembly and the second screen assembly.
[0058] Furthermore, such as Figure 7-9 As shown, the dual-axis hinge 11 also includes:
[0059] The first slide rail limiting member 116 has a first end connected to the first shaft gear 1151 and a second end slidably connected to the first connecting member 113, in order to limit the flip angle of the first screen assembly 21.
[0060] The second slide rail limiting member 117 has its first end connected to the second shaft gear 1152 and its second end slidably connected to the second connecting member 114, in order to limit the flip angle of the second screen assembly 22.
[0061] The first slide rail limiting member 116 and the second slide rail limiting member 117 are used to fix and limit the travel of the first screen assembly 21 and the second screen assembly 22, so that the flip angle of the two is not too large.
[0062] For example, such as Figure 8-9As shown, the dual-axis hinge 11 also includes a mounting member 118, which is sleeved on the ends of the first axis 111 and the second axis 112. The mounting member 118 is used to fix the hinge cover 24, which is used to cover the dual-axis hinge 11 and prevent the first screen assembly and the second screen assembly from being exposed when unfolded. The mounting member 118 is movably connected to the first connecting member 113 and the second connecting member 114. Specifically, the mounting member 118 is provided with a protrusion 1181 and a clearance opening 1182 for the reciprocating movement of the first connecting member 113 and the second connecting member 114. Slide grooves 1132 are respectively provided at corresponding positions of the first connecting member 113 and the second connecting member 114. The slide grooves 1132 are located in the clearance openings 1182 and the protrusions 1181 are inserted into the slide grooves 1132. When the first screen assembly 21 drives the first connecting member 113 to flip open, due to the limiting connection with the first slide groove limiting member 116, the first connecting member 113 synchronously drives the first slide groove limiting member 116 to flip. The first slide groove limiting member 116 then synchronously drives the first shaft gear 1151 to rotate. Due to the meshing connection between the first shaft gear 1151 and the second shaft gear 1152, the first screen assembly 21 and the second screen assembly 22 flip open relative to each other. Furthermore, the rotation of the first shaft gear 1151 and the second shaft gear 1152 synchronously drives the first shaft 111 and the second shaft 112 to rotate, respectively. The second shaft 112 then synchronously drives the first gear 131 of the coaxially connected transmission assembly 13 to rotate, thereby driving the second gear 132 to rotate.
[0063] Furthermore, such as Figure 8 As shown, the dual-axis hinge 11 also includes a connector 119. The first end of the connector 119 is sleeved on the first shaft 111 and the second shaft 112. The connector 119 and the mounting member 118 are spaced apart, and the second end of the connector 119 is fixedly mounted on the hinge cover 24. The connection between the connector 119 and the mounting member 118 and the hinge cover 24 ensures the stability of the connection between the dual-axis hinge and the hinge cover 24.
[0064] For example, the second end of the first sliding groove limiting member 116 and the second end of the second sliding groove limiting member 117 are both constructed as sliding holes 1161, and the first connecting member 113 and the second connecting member 114 are both provided with limiting shafts 1131, and the sliding holes 1161 are correspondingly slidably connected to the limiting shafts 1131.
[0065] For example, the first slide groove limiting member 116 and the first shaft gear 1151 are constructed as one piece; the second slide groove limiting member 117 and the second shaft gear 1152 are constructed as one piece.
[0066] like Figure 5-6As shown, to facilitate user viewing of the screen, the angle between the first screen assembly 21 and the second screen assembly 22 can be up to 180 degrees. At this angle, the two screens, 211 and 221, are on the same plane, which is sufficient to meet the user's viewing needs. Therefore, the rotation angles of the first shaft gear 1151 and the second shaft gear 1152 on the first shaft are each 90 degrees. Thus, by constructing the first shaft gear 1151 and the first end of the first sliding groove limiting member 116, and the first ends of the second shaft gear 1152 and the second sliding groove limiting member 117 as a single unit, it is possible to facilitate the meshing and rotation of the first shaft gear 1151 and the second shaft gear 1152, while also facilitating the sliding and limiting of the first sliding groove limiting member 116 and the second sliding groove limiting member 117.
[0067] The first slide groove limiting member 116 and the first shaft gear 1151 are constructed as one piece, and the second slide groove limiting member 117 and the second shaft gear 1152 are constructed as one piece, which can meet the strength requirements of both and facilitate production and manufacturing.
[0068] In one possible implementation, such as Figure 7 As shown in the figures of this application (for ease of display, the links on the chain 133 are only shown at the positions of the first and second gears, and the middle portion is not shown), the transmission assembly 13 includes:
[0069] The first gear 131 is coaxially mounted on the second shaft 112.
[0070] The second gear 132 is coaxially mounted on the shaft 121 of the single-shaft hinge 12, and the second gear 132 is connected to the first gear 131 via a chain 133. The rotation angle ratio of the gear set 115, the first gear 131, and the second gear 132 is 1.5:1.5:1. For example, the rotation angle ratio can be achieved by setting the ratio of the effective number of teeth of the gears.
[0071] For example, the first shaft gear 1151 and the second shaft gear 1152 of the gear set 115 have the same rotation angle, and the rotation angle ratio of the first shaft gear 1151, the first gear 131 and the second gear 132 is 1.5:1.5:1.
[0072] For example, when the first shaft gear 1151 and the second shaft gear 1152 both rotate at an angle of 45 degrees, the included angle between the first screen assembly 21 and the second screen assembly 22 is 90 degrees. Since the first gear 131 is coaxially mounted on the second shaft 112 and rotates at the same angle as the first shaft gear 1151, the rotation angle of the first gear is 45 degrees and the rotation angle of the second gear is 30 degrees. That is to say, the included angle between the second screen assembly 22 and the system end 23 is 30 degrees, and the second screen assembly 22 is raised in the vertical direction relative to the system end 23.
[0073] For example, when the first shaft gear 1151 rotates at an angle of 60 degrees, the corresponding second gear 132 rotates at an angle of 40 degrees, and the included angle between the second screen assembly 22 and the system terminal 23 is 40 degrees. When the first shaft gear 1151 rotates at an angle of 90 degrees, the corresponding second gear 132 rotates at an angle of 60 degrees, and the included angle between the second screen assembly 22 and the system terminal 23 is 60 degrees. Thus, as the rotation angle of the first screen assembly 21 and the second screen assembly 22 increases, the rotation angle of the second screen assembly 22 relative to the system terminal 23 also increases, causing the second screen assembly 22 to synchronously drive the first screen assembly 21 to rise vertically.
[0074] For example, the single-axis hinge 12 includes a pivot 121, a first fixing member 122 mounted on the pivot 121, and a second fixing member 123 mounted on the pivot 121. The first fixing member is mounted on the system end 23, and the second fixing member 123 is mounted on the second screen assembly 22. A second gear 132 is coaxially mounted on the pivot 121. When the first gear drives the second gear 132 to rotate via a chain, the second gear drives the pivot 121 to rotate synchronously, causing the second screen assembly 22 to rotate around the system end 23.
[0075] Secondly, such as Figure 1-6 As shown, this application also provides an electronic device 2, including a first screen assembly 21, a second screen assembly 22 and a system terminal 23, and also includes the aforementioned dual-screen lifting structure 1.
[0076] For example, such as Figure 5-6 As shown, the first screen assembly 21 includes a first screen 211 and a first screen housing 212 for mounting the first screen. The first screen housing 212 is fixedly connected to the first connecting component 113 of the dual-screen lifting structure.
[0077] The second screen assembly 22 includes a second screen 221 and a second screen housing 222 for mounting the second screen. The second screen housing 222 is fixedly connected to the second connecting component 114 of the dual-screen lifting structure.
[0078] For example, system terminal 23 has a housing 231, on which a receiving cavity 232 for accommodating a second screen assembly 22 is formed, and the second screen assembly 22 is connected to the receiving cavity 232 via a single pivot hinge. The first fixing member 122 of the single pivot hinge is fixedly connected to the housing 231, and the second fixing member 123 is fixedly connected to the second screen housing 222.
[0079] This application adopts an integrated flip structure. The first screen component 21 easily drives the second screen component 22. Through a clever linkage mechanism, the two screens unfold naturally and synchronously during operation, allowing for quick splicing into a vertical, elongated screen without cumbersome steps. The screen ratio after splicing is close to the common mobile phone display specification (20:10), suitable for various application scenarios. At the same time, when the overall structure is closed, it returns to the size of approximately a 15-inch (16:9) laptop computer, combining applicability and portability in one step. Furthermore, the time taken is significantly optimized to within 5 seconds compared to the time taken by related technologies that use a roll-up vertical screen.
[0080] In this application, the electronic device 2 includes, but is not limited to, a laptop computer. Taking a laptop computer as an example, the first screen housing 212 of the first screen assembly is fixedly connected to the first connecting member 113, the second screen housing 222 of the second screen assembly is fixedly connected to the second connecting member 113, the outer shell 231 of the system end is connected to the first fixing member 122 of the single-axis hinge 12, and the second fixing member 123 of the single-axis hinge 12 is fixedly connected to the second screen housing 222. Thus, when the first screen assembly 21 is opened by rotating counterclockwise, the first screen assembly 21 and the second screen assembly 22 are synchronously driven to flip and unfold under the action of the dual-axis hinge 11. Furthermore, the first gear 131 on the second axis 112 drives the second gear 132 to rotate through the chain 133, thereby synchronously driving the pivot 121 of the single-axis hinge to rotate, causing the second screen assembly 22 to rotate around the system end 23. Due to the defined rotation angle ratios of the first shaft gear 1151, the second shaft gear 1152, the first gear 131, and the second gear 132, when the first shaft gear 1151 and the second shaft gear 1152 each rotate 90 degrees, the included angle between the first screen assembly 21 and the second screen assembly 22 is 180 degrees, the rotation angle of the second gear 132 is 60 degrees, and the included angle between the second screen assembly 22 and the system terminal 23 is also 60 degrees. This causes the second gear 132 to synchronously drive the second end of the second screen assembly 22, thereby lifting the first screen assembly 21 vertically to a certain height. At this point, the laptop is in the open state. Figure 4-6 As shown, users can engage in AI interactive chat through the screens on the first screen component 21 and the second screen component 22, while also using other work interfaces, increasing the screen's viewing range, allowing users to enjoy a wider field of view, and bringing a better user experience.
[0081] When the first screen assembly 21 is rotated clockwise, driven by the dual-axis hinge 11, the transmission assembly 13, and the single-axis hinge 12, the angle between the first screen assembly 21 and the second screen assembly 22 gradually decreases, and they gradually fall vertically until the second screen assembly 22 falls back into the receiving cavity 232. The first screen assembly 21 is stacked on top of the second screen assembly 22 and the system terminal 23. At this time, the laptop is in a closed state, as shown below. Figure 1-3 As shown.
[0082] It should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

[0083] The above description is merely a specific embodiment of this disclosure, but the scope of protection of this disclosure is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this disclosure should be included within the scope of protection of this disclosure. Therefore, the scope of protection of this disclosure should be determined by the scope of the claims.
