Description

Technical Field

[0001] This utility model relates to the field of hinge structure of tablet keyboards, specifically to a dual-axis 360° flip-up tablet keyboard. Background Technology

[0002] Tablet computers, with their portability and versatility, have been widely used in various fields such as office work, learning, and creative design. In practical use, tablet keyboards and styluses have become core accessories for enhancing the usability of tablets. Keyboards meet the needs of efficient input, while styluses are suitable for precise writing, drawing, and other fine operations. The combination of these two with tablets is gradually becoming the mainstream usage mode.

[0003] However, current tablet keyboards on the market have significant limitations in their structural design, and most of them cannot achieve a 360° rotation function when connected to the tablet. After a user finishes typing on the keyboard, if they need to switch to writing or drawing with the stylus, they must first detach the tablet from the keyboard to adjust it to a suitable posture. This operation method keeps the tablet, keyboard, and stylus in a relatively separate state, failing to create a seamless, integrated user experience.

[0004] Frequent disassembly and installation not only increases the cumbersomeness of the operation process, but may also cause damage to the device's connection structure due to repeated plugging and unplugging, reducing the product's lifespan. In addition, the detachable usage scenario also limits the tablet's efficiency in quickly switching between different office modes, failing to meet users' needs for convenience and flexibility in mobile office work. Utility Model Content

[0005] The purpose of this invention is to provide a dual-axis 360° flip-up tablet keyboard to solve the above-mentioned problems.

[0006] To achieve the above objectives, this utility model provides a dual-axis 360° rotatable tablet keyboard, including a keyboard body, a tablet adsorption assembly, and a dual-axis rotation assembly connecting the two. The dual-axis rotating assembly includes a dual-axis component and a dual-axis fixing base. The dual-axis component and the dual-axis fixing base are interference-fitted. The keyboard body is connected to the dual-axis component through a first connecting tube, and the tablet adsorption assembly is connected to the dual-axis component through a second connecting tube. The first connecting tube and the dual-axis fixed base form a first rotating unit, which can rotate 180° around the dual-axis component and is positioned by a limiting structure; the second connecting tube and the dual-axis fixed base form a second rotating unit, which can rotate 180° around the dual-axis component and is positioned by a limiting structure. The 360° flipping function is achieved by superimposing the rotational movements of the first rotating unit and the second rotating unit.

[0007] Furthermore, in the aforementioned dual-axis 360° flip-up tablet keyboard, the first connecting tube and the second connecting tube are arranged in parallel, and there are two dual-axis components and two dual-axis fixing seats, with each of the two dual-axis components corresponding to one of the two dual-axis fixing seats, respectively located at both ends of the first connecting tube and the second connecting tube.

[0008] Furthermore, in the aforementioned dual-axis 360° flip-up tablet keyboard, the rotational torque applied by the dual-axis rotation assembly to the second connecting tube is greater than the rotational torque applied to the first connecting tube.

[0009] Furthermore, in the aforementioned dual-axis 360° flip-up tablet keyboard, the first connecting tube is fixedly connected to the keyboard body by threaded fasteners, and the inner wall of the first connecting tube is interference-fitted with the dual-axis component.

[0010] Furthermore, in the aforementioned dual-axis 360° rotatable tablet keyboard, the tablet adsorption assembly includes a plate A and a plate B. The tablet computer is adsorbed onto the plate B, and the second connecting tube is fixedly connected to the plate B by an adhesive. The inner wall of the second connecting tube is interference-fitted with the dual-axis component.

[0011] Furthermore, in the aforementioned dual-axis 360° rotatable tablet keyboard, the A board and the B board are hinged together by a torsion hinge assembly. The torsion hinge assembly can provide rotational damping to achieve angle positioning, and the A board can be flipped around the torsion hinge assembly to adjust the support angle.

[0012] Furthermore, in the aforementioned dual-axis 360° flip-up tablet keyboard, the torque hinge assembly includes a torque shaft and a limiting shaft. The limiting shaft and the torque shaft are arranged parallel to each other and rotate synchronously, enabling the A-plate to achieve a support angle adjustment of 90 degrees to 180 degrees around the torque hinge assembly.

[0013] Furthermore, in the aforementioned dual-axis 360° flip-up tablet keyboard, the limiting structure includes a limiting protrusion and a limiting groove. The limiting protrusion is disposed on the dual-axis fixed base, and the limiting grooves are respectively disposed on the first connecting tube and the second connecting tube. When the first connecting tube or the second connecting tube rotates to 180°, the limiting protrusion engages with the corresponding limiting groove to achieve positioning.

[0014] Furthermore, in the aforementioned dual-axis 360° rotatable tablet keyboard, the side of the B board facing the tablet is provided with a magnetic adsorption component, and multiple permanent magnets are embedded inside the magnetic adsorption component, which are distributed in a matrix.

[0015] Furthermore, in the aforementioned dual-axis 360° flip-up tablet keyboard, the outer surface of the B board is covered with a PU leather layer, which is fixed to the B board by an adhesive, and the surface of the PU leather layer is provided with a scratch-resistant and wear-resistant coating.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects: This invention utilizes a dual-axis rotating assembly comprising a dual-axis mounting base, dual-axis components, and two sets of connecting tubes. This allows the keyboard body and the tablet adsorption assembly to form a first rotating unit and a second rotating unit, each capable of rotating 180° around the dual-axis components. The combined motion of the two rotating units achieves a 360° flip function, thus solving the problem in existing products where users need to frequently disassemble the tablet when switching between keyboard and stylus usage. Flexible mode switching can be achieved without disassembling the device. This not only allows the tablet, keyboard, and stylus to form a tightly integrated unit, simplifying operation and improving scene switching efficiency, but also avoids damage to the device connection structure caused by repeated plugging and unplugging, enhancing the user experience.

It should be understood that those skilled in the art can modify the present invention described herein while still achieving its advantageous effects.

[0021] Based on the teachings of this specification, those skilled in the art can form new technical solutions through cross-combination of different implementation methods without creating technical contradictions. Such variations should all be considered to fall within the protection scope of this utility model.

[0022] The present invention will be described more specifically by way of example in the following paragraphs with reference to the accompanying drawings. The advantages and features of the present invention will become clearer from the following description and claims. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0023] like Figures 1-8 As shown, this embodiment discloses a dual-axis 360° flip-up tablet keyboard, aiming to solve the problem of existing tablet keyboards being unable to flip flexibly, resulting in cumbersome device switching, and to achieve an integrated user experience of keyboard, tablet, and capacitive pen. The keyboard consists of a keyboard body 1, a tablet magnetic attachment component 2, and a dual-axis rotating component 3 connecting the two. The 360° flip function is mainly achieved through the coordinated movement of the dual-axis rotating component 3, meeting the user's need for seamless switching between keyboard typing and capacitive pen writing scenarios.

[0024] Among them, such as Figure 1 and Figure 3 The dual-axis rotating assembly 3 includes a dual-axis component 31 and a dual-axis fixing base 32. The keyboard body 1 and the tablet suction assembly 2 are connected to the dual-axis component 31 via different connecting tubes. Specifically, the dual-axis component 31 has two shafts. The keyboard body 1 is assembled with one shaft of the dual-axis component 31 via a first connecting tube 11, and the tablet suction assembly 2 is assembled with the other shaft of the dual-axis component 31 via a second connecting tube 21. These two connecting tubes allow the two to form independent yet coordinated rotating units. The first connecting tube 11 and the dual-axis fixing base 32 together constitute the first rotating unit, and the second connecting tube 21 and the dual-axis fixing base 32 together constitute the second rotating unit. Both rotating units can rotate 180° around the dual-axis component 31, and after rotating to the correct position, they can be stably positioned by a limiting structure. Through the superposition of the 180° rotational movements of the two units, a complete 360° flip function between the keyboard and the tablet 4 is finally achieved.

[0025] In this embodiment, there are two dual-axis components 31 and two dual-axis fixing seats 32, and the two dual-axis components 31 and the two dual-axis fixing seats 32 are arranged in a one-to-one correspondence, providing symmetrical support for the overall structure. The keyboard body 1 cooperates with the dual-axis components 31 through the first connecting tube 11. Specifically, the first connecting tube 11 and the keyboard body 1 are fixedly connected by screws or other threaded fasteners. This connection method is not only convenient to assemble, but also prevents loosening during use. Meanwhile, as... Figure 6 and Figure 7 As shown, the first connecting pipe 11 and the second connecting pipe 21 are arranged in parallel, and two double shaft parts 31 are respectively located at both ends of the first connecting pipe 11 and the second connecting pipe 21. The inner wall of the first connecting pipe 11 and the double shaft parts 31 at both ends are interference-fitted, and the connection stability is further improved by the tight fit between the components.

[0026] Correspondingly, the flat plate adsorption assembly 2 is connected to the dual-axis components 31 at both ends via the second connecting tube 21. Specifically, the second connecting tube 21 and the flat plate adsorption assembly 2 are fixedly connected by adhesive, and the inner wall of the second connecting tube 21 and the dual-axis components 31 at both ends are interference-fitted. This ensures the reliability of the connection and also makes the overall force of the dual-axis rotating assembly 3 uniform, resulting in a smooth and stable rotation process. It is worth noting that the interference fit between each dual-axis component 31 and the corresponding dual-axis fixing seat 32 not only solves the problem of wobbling of the rotating assembly, but also gives the overall structure both symmetry and stability.

[0027] It should be noted that the rotational torque applied by the dual-axis rotating assembly 3 to the second connecting pipe 21 is greater than the rotational torque applied to the first connecting pipe 11. This difference in rotational torque ensures that the first rotating unit rotates 180° around the dual-axis assembly 31 and is positioned by the limiting structure before the second rotating unit can rotate 180° around the dual-axis assembly 31 and be positioned by the limiting structure. Ultimately, the superposition of two 180° rotations achieves a 360° flip, preventing structural disorder during the flipping process. The specific rotation angles of the dual-axis rotating assembly 3 are as follows: Figure 1 , 3 As shown in Figures 5 and 6, these correspond to 0°, 360°, and 150°, respectively.

[0028] To ensure that the two rotating units can be stably positioned after rotating 180°, the limiting structure in this embodiment specifically includes a limiting protrusion (not shown) and a limiting groove (not shown). The limiting protrusion is set on the dual-axis fixing base 32, and the limiting grooves are respectively opened on the first connecting tube 11 and the second connecting tube 21. When the first connecting tube 11 drives the keyboard body 1 to rotate 180°, or the second connecting tube 21 drives the flat plate adsorption assembly 2 to rotate 180°, the limiting protrusion on the dual-axis fixing base 32 will engage with the limiting groove on the corresponding connecting tube to form a mechanical limiting fixation, ensuring the structural stability after flipping and providing reliable support for input or writing.

[0029] Furthermore, such as Figure 8 The flat panel adsorption assembly 2 includes a plate A 23 and a plate B 24. The tablet computer 4 is directly adsorbed onto plate B 24 for fixation. To enhance the stability of the tablet computer 4, a magnetic adsorption component (not shown) is provided on the side of plate B 24 facing the tablet computer 4. This magnetic adsorption component has multiple permanent magnets embedded inside, and the permanent magnets are distributed in a matrix. This distribution method allows the adsorption force to be evenly applied to the back of the tablet computer 4, avoiding the problem of the tablet computer 4 falling off due to uneven local force. At the same time, the outer surface of the flat panel adsorption assembly 2 is covered with a PU (polyurethane) leather layer 22. The PU leather layer 22 is a commonly used synthetic material with wear resistance, flexibility, and easy processing characteristics. It is often used for surface coating of various products to improve appearance and durability. The PU leather layer 22 is tightly fixed to the flat panel adsorption assembly 2 with adhesive, and the surface of the PU leather layer 22 also has a scratch-resistant and wear-resistant coating, which not only improves the texture and grip comfort of the product, but also effectively resists scratches during daily use and extends the product's service life.

[0030] To adapt to different viewing angle requirements in various usage scenarios, the A-board 23 and the B-board 24 are hinged together by a torsion hinge assembly 25. This torsion hinge assembly 25 provides stable rotational damping, allowing the flat plate 4 to be precisely positioned after angle adjustment without the need for additional support structures. In this embodiment, the torsion hinge assembly 25 consists of hinge pivots, specifically including two torsion shafts 251 and two limiting shafts 252. The limiting shafts 252 and the torsion shafts 251 are arranged parallel to each other and rotate synchronously, enabling the A-board 23 to achieve a support angle adjustment of 90 degrees to 180 degrees around the torsion hinge assembly 25. This ensures precise adaptation whether it is the tilt angle during keyboard input or the flat angle during capacitive pen writing.

[0031] In addition, an anti-slip pad is provided on the side of the A board 23 away from the torsion hinge assembly 25. The anti-slip pad is made of silicone material and has anti-slip texture on the surface, which can effectively increase the friction with the placement surface, prevent the keyboard from sliding and shifting during use, and further improve the stability of use.

[0032] In addition, the keyboard body 1 in this embodiment is composed of key assembly 12 and bottom cover 13.

[0033] In this embodiment, the dual-axis 360° flip-up tablet 4 keyboard allows the user to magnetically attach the tablet 4 to the B board 24 for efficient input during daily office work. When switching to capacitive pen writing or drawing, there's no need to disassemble the tablet 4. Simply use the dual-axis rotation component 3 to rotate the keyboard body 1 relative to the tablet 4. The first and second rotation units each rotate 180°, resulting in a 360° rotation with the tablet 4 screen facing the user. Simultaneously, the angle of the A board 23 can be adjusted to a comfortable viewing angle using the torque hinge component 25, allowing direct operation with the capacitive pen. The entire switching process is smooth and convenient, ultimately achieving integrated use of the keyboard, tablet 4, and capacitive pen.

[0034] The above are merely preferred embodiments of this utility model and do not constitute any limitation on this utility model. Any equivalent substitutions or modifications made by those skilled in the art to the technical solutions and contents disclosed in this utility model without departing from the scope of the technical solutions of this utility model shall still fall within the protection scope of this utility model.
