[0004] With the rapid development of society and the continuous improvement of people's living standards, electronic products have become a necessity in people's lives. There are many types of electronic products, including tablet devices. In order to make it easier for people to use tablets, businesses have invented some tablet accessories, including a folding Bluetooth keyboard stand.

[0005] Existing folding Bluetooth keyboard stands have certain drawbacks. Because the tablet stand is tilted when in use, the weight of the tablet is greater than the keyboard, making it unstable and prone to warping and tipping. Operating the tablet can also easily cause the tablet and the Bluetooth keyboard stand to topple over. Furthermore, to accommodate multiple angles, some folding stands employ multiple folding structures, which take up space on the keyboard, preventing the keyboard from being optimally positioned and impacting the user's keystroke experience.

[0058] Please refer to Figure 1, which is a schematic diagram of the structure of the first embodiment of the foldable keyboard of the present application. The foldable keyboard 1 provided in this embodiment of the application is applied to a mobile device 2, where the mobile device can be a tablet computer, a mobile phone, etc. The foldable keyboard 1 includes a cover assembly 11, a keyboard assembly 12, and a support assembly 13.

[0059] The cover assembly 11 is used to place the mobile device 2. The first end of the keyboard assembly 12 is rotatably connected to the cover assembly and includes a keyboard 121. The keyboard 121 is connected to the mobile device 2. The first end of the support assembly 13 is connected to the cover assembly 11, and the second end of the support assembly 13 is slidably connected to the keyboard assembly 12.

[0060] Specifically, when the cover assembly 11 and the keyboard assembly 12 are in the open position, that is, when an angle exists between the cover assembly 11 and the keyboard assembly 12, the second end of the support assembly 13 slides relative to the keyboard assembly 12 in a direction away from the second end of the keyboard assembly 12, and the support assembly 13 is used to support the cover assembly 11. The first end of the keyboard assembly 12 and the second end of the keyboard assembly 12 are opposite ends of the keyboard assembly 12.

[0061] When the cover assembly 11 and the keyboard assembly 12 are in the open state, that is, there is an angle between the cover assembly 11 and the keyboard assembly 12, and the cover assembly 11 rotates relative to the keyboard assembly 12 to increase the angle between the cover assembly 11 and the keyboard assembly 12, the support assembly 13 moves relative to the keyboard assembly 12 in the direction away from the second end of the keyboard assembly 12 to increase the support area of ​​the cover assembly 11, thereby avoiding the situation where the angle between the cover assembly 11 and the keyboard assembly 12 is too large and the cover assembly 11 tilts and overturns, thereby improving the safety of the foldable keyboard 1 and improving the user experience of the foldable keyboard 1.

[0062] At the same time, when the cover assembly 11 rotates relative to the keyboard assembly 12 to reduce the angle between the cover assembly 11 and the keyboard assembly 12, the second end of the support assembly 13 slides relative to the keyboard assembly 12 toward the second end of the keyboard assembly 12, thereby reducing the space occupied by the folding keyboard 1 when the cover assembly 11 and the keyboard assembly 12 are in a closed state (the angle between the cover assembly 11 and the keyboard assembly 12 is 0), thereby ensuring the aesthetics of the folding keyboard 1.

[0063] It is understandable that when the cover assembly 11 rotates relative to the keyboard assembly 12 and the angle between the cover assembly 11 and the keyboard assembly 12 changes, the support assembly 13 slides as the angle between the cover assembly 11 and the keyboard assembly 12 changes.

[0064] In one embodiment, referring to Figures 1 and 2, Figure 2 is a schematic structural diagram of a second embodiment of the foldable keyboard of the present application. When the cover assembly 11 rotates relative to the keyboard assembly 12 and the angle between the cover assembly 11 and the keyboard assembly 12 increases, the support assembly 13 slides relative to the keyboard assembly 12 in a direction away from the second end of the keyboard assembly 12, thereby increasing the support area for the cover assembly 11.

[0065] In another embodiment, when the angle between the cover assembly 11 and the keyboard assembly 12 decreases and the cover assembly 11 and the keyboard assembly 12 are about to close, as the angle between the cover assembly 11 and the keyboard assembly 12 decreases, the support assembly 13 slides relative to the keyboard assembly 12 toward the second end of the keyboard assembly 12. In other words, the support assembly 13 slides in response to changes in the angle between the cover assembly 11 and the keyboard assembly 12. The support area of ​​the support assembly 13 on the cover assembly 11 increases or decreases as the angle between the cover assembly 11 and the keyboard assembly 12 increases, thereby improving the flexibility of the support assembly 13.

[0066] Alternatively, please refer to FIG3 , which is a schematic structural diagram of a third embodiment of the foldable keyboard of the present application. The support assembly 13 includes a support member 131 and a swing member 132 .

[0067] One end of the support member 131 is connected to the cover assembly 11, the first end of the swing member 132 is rotatably connected to the side of the keyboard assembly 12 away from the keyboard 121, the second end of the swing member 132 is connected to the other end of the support member 131, and the other end of the support member 131 is slidingly connected to the keyboard assembly 12 through the swing member 132.

[0068] Specifically, during the rotation of the cover assembly 11 relative to the keyboard assembly 12, when the angle between the cover assembly 11 and the keyboard assembly 12 increases, the swing member 132 swings with the connection between the swing member 132 and the keyboard assembly 12 as the rotation center, thereby driving the support member 131 to move relative to the keyboard assembly 12 in a direction away from the second end of the keyboard assembly 12.

[0069] Alternatively, please refer to FIG4 , which is a schematic structural diagram of a fourth embodiment of the foldable keyboard of the present application. The support member 131 includes a connecting belt 1311 and a sliding plate 1312 .

[0070] One end of the connecting belt 1311 is connected to the cover assembly 11, and the other end of the connecting belt 1311 is connected to the sliding plate 1312. The second end of the swing member 132 is connected to the sliding plate 1312, and the sliding plate 1312 is slidably connected to the keyboard assembly 12 through the swing member 132.

[0071] During the rotation of the cover assembly 11 relative to the keyboard assembly 12, when the angle between the cover assembly 11 and the keyboard assembly 12 increases, the swing member 132 swings to drive the sliding plate 1312 to slide relative to the keyboard assembly 12 in a direction away from the second end of the keyboard assembly 12, and the connecting belt 1311 shrinks.

[0072] In one embodiment, the connecting belt 1311 is elastic, wherein the connecting belt 1311 can be an elastic elastic belt or an elastic belt. Furthermore, when the cover assembly 11 rotates relative to the keyboard assembly 12, when the angle between the cover assembly 11 and the keyboard assembly 12 increases, the sliding plate 1312 moves relative to the keyboard assembly 12 in a direction away from the keyboard assembly 12, and the connecting belt 1311 contracts. As shown in Figure 1, when the angle between the cover assembly 11 and the keyboard assembly 12 becomes larger, and the sliding plate 1312 slides relative to the keyboard assembly 12 in a direction away from the second end of the keyboard assembly 12, the distance between the cover assembly 11 and the sliding plate 1312 becomes smaller, and the connecting belt 1311 will accumulate between the cover assembly 11 and the sliding plate 1312, affecting the aesthetics of the folding keyboard 1.

[0073] In this embodiment, the connecting strap 1311 is elastic. When the distance between the cover assembly 11 and the sliding plate 1312 decreases, the connecting strap 1311 contracts, thereby improving the aesthetics of the foldable keyboard 1. Furthermore, when the cover assembly 11 and the keyboard assembly 12 are closed, the connecting strap 1311 can cover the cover assembly 11, shielding the connection between the cover assembly 11 and the keyboard assembly 12, further improving the aesthetics of the foldable keyboard 1.

[0074] Alternatively, please refer to Figures 4 and 5. Figure 5 is a schematic diagram of a partial structure of the folding keyboard in Figure 4. The support assembly 13 includes a sliding member 133. The second end of the swinging member 132 has a guide groove 1321. One end of the sliding member 133 is disposed in the guide groove 1321, and the other end of the sliding member 133 is connected to the sliding plate 1312.

[0075] During the swinging process of the swinging member 132, one end of the sliding member 133 slides in the guide groove 1321, thereby driving the sliding plate 1312 to slide along the first direction X. The first direction X is a direction perpendicular to the end surface of the first end of the keyboard assembly 12, that is, the first direction X is parallel to the normal direction of the end surface of the first end of the keyboard assembly 12. When the sliding plate 1312 slides along the first direction X, the sliding efficiency of the sliding plate 1312 along the second end away from the keyboard assembly 12 is higher than when the sliding plate 1312 slides along other directions. This allows the sliding plate 1312 to quickly increase the support area for the cover assembly 11, thereby improving the sliding efficiency of the sliding plate 1312.

[0076] Specifically, when the cover assembly 11 rotates relative to the keyboard assembly 12 and the angle between the cover assembly 11 and the keyboard assembly 12 increases, the swing member 132 swings, and one end of the sliding member 133 slides in the guide groove 1321, limiting the sliding direction of the sliding plate 1312, so that the sliding plate 1312 moves away from the second end of the keyboard assembly 12 along the first direction X.

[0077] Alternatively, please refer to Figures 3, 5, and 6. Figure 6 is a schematic structural diagram of the first embodiment of the cover assembly of the present application. One end of the cover assembly 11 includes a rotating rod 111, and the first end of the keyboard assembly 12 includes two fixing members 122. The cover assembly 11 and the keyboard assembly 12 are rotatably connected via the rotating rod 111 and the fixing members 122.

[0078] The two fixing members 122 are rotatably connected to the ends of the rotating rod 111, respectively. In one embodiment, the fixing member 122 is a hollow structure having a receiving cavity. The foldable keyboard 1 also includes a fixed rotating shaft, which is disposed in the receiving cavity of the fixing member 122 and connected to the rotating rod 111, so as to achieve the rotational connection between the cover assembly 11 and the keyboard assembly 12 via the rotating rod 111 and the fixing member 122. In another embodiment, the fixing member 122 and the rotating rod 111 can also be connected via a snap-fit ​​structure. This application does not limit the specific form of the connection between the fixing member 122 and the rotating rod 111 to achieve the rotational connection between the cover assembly 11 and the keyboard assembly 12.

[0079] In one embodiment, the fixing member 122 may include an extension member, and the extension member extends in the direction of the fixing member 122 pointing to the rotating rod 111, so that the extension member blocks the rotating rod 111, thereby improving the aesthetics of the folding keyboard 1.

[0080] Furthermore, the body of the rotating rod 111 has a swing member guide groove 1111, which is arranged in a direction away from the end surface of the rotating rod 111. The first end of the swing member 132 has a swing member protrusion 1322, which is arranged in the swing member guide groove 1111.

[0081] When the cover assembly 11 rotates relative to the keyboard assembly 12 and the angle between the cover assembly 11 and the keyboard assembly 12 changes, the rotating rod 111 rotates relative to the fixing member 122, and then the swinging member guide groove 1111 rotates following the rotating rod 111, and the swinging member convex shaft 1322 moves in the swinging member guide groove 1111 to drive the swinging member 132 to swing.

[0082] Specifically, because the rotating rod 111 is disposed on the cover assembly 11, when the cover assembly 11 rotates relative to the keyboard assembly 12, the rotating rod 111 rotates accordingly, and the swing member guide groove 1111 rotates accordingly. Since the first end of the swing member 132 is fixed to the keyboard assembly 12, and the swing member protrusion 1322 at the first end of the swing member 132 is disposed in the swing member guide groove 1111, the swing member 132 is driven to swing with the connection between the swing member 132 and the keyboard assembly 12 as the rotation center. The swinging of the swing member 132 then drives the sliding plate 1312 to slide along the first direction X, allowing the sliding plate 1312 to slide as the angle between the cover assembly 11 and the keyboard assembly 12 changes, thereby improving the sliding flexibility of the sliding plate 1312.

[0083] Alternatively, referring to Figures 4 and 5 , the keyboard assembly 12 includes a housing 123, a keyboard 121 disposed on a first surface of the housing 123, and a support assembly 13 disposed on a second surface of the housing 123. The first and second surfaces are opposite surfaces of the housing 123. In one embodiment, the first surface is the front surface of the housing 123, and the second surface is the back surface of the housing 123. The keyboard 121 is disposed on the front surface of the housing 123, while the support assembly 13 is disposed on the back surface of the housing 123. The housing 123 shields the support assembly 13, thereby improving the aesthetics of the foldable keyboard 1.

[0084] The second surface of the housing 123 includes a first groove 124 . The first groove 124 is disposed near the first end of the keyboard assembly 12 . That is, the first groove 124 is disposed at an end of the housing 123 near the rotating rod 111 .

[0085] The sliding plate 1312 and the swinging member 132 are disposed within the first groove 124, with the sliding plate 1312 connected to the bottom of the first groove 124 via the swinging member 132. Specifically, the first end of the swinging member 132 is connected to the bottom of the first groove 124. When the cover assembly 11 rotates relative to the keyboard assembly 12 and the angle between the cover assembly 11 and the keyboard assembly 12 increases, the swinging member 132 swings, causing the sliding plate 1312 to slide out of the first groove 124 along the first direction X, thereby supporting the cover assembly 11. Furthermore, when the cover assembly 11 rotates relative to the keyboard assembly 12 and the angle between the cover assembly 11 and the keyboard assembly 12 decreases, the swinging member 132 swings in the opposite direction, causing the sliding plate 1312 to slide back into the first groove 124. The first groove 124 accommodates the sliding plate 1312, thereby reducing the space occupied by the foldable keyboard 1 and ensuring the aesthetics of the foldable keyboard 1.

[0086] For example, but not limited to, when the angle between the cover assembly 11 and the keyboard assembly 12 increases, the swinging member 132 may swing clockwise, thereby driving the sliding plate 1312 to gradually slide out of the first groove 124. When the angle between the cover assembly 11 and the keyboard assembly 12 decreases, the swinging member 132 may swing counterclockwise, thereby driving the sliding plate 1312 to gradually slide back into the first groove 124. When the angle between the cover assembly 11 and the keyboard assembly 12 increases, the swinging direction of the swinging member 132 is opposite to the swinging direction of the swinging member 132 when the angle between the cover assembly 11 and the keyboard assembly 12 decreases, thereby causing the sliding plate 1312 to slide out of the first groove 124 or slide back into the first groove 124 in opposite directions. This allows the sliding plate 1312 to provide different support areas for the cover assembly 11 according to the change in the angle between the cover assembly 11 and the keyboard assembly 12, thereby improving the practicality of the foldable keyboard 1.

[0087] At the same time, since the connecting belt 1311 is connected to one end of the sliding plate 1312, when the cover assembly 11 and the keyboard assembly 12 are in a closed state and the sliding plate 1312 is located in the first groove 124, the connecting belt 1311 extends to cover the connection between the cover assembly 11 and the keyboard assembly 12, that is, the rotating rod 111 and the fixing member 122, further improving the aesthetics of the folding keyboard 1 and improving the user experience of the folding keyboard 1.

[0088] Optionally, as shown in FIG. 5 , the keyboard assembly 12 further includes a second groove 125 . The second groove 125 is disposed at the bottom of the first groove 124 , and the second groove 125 is fan-shaped.

[0089] The swinging member 132 is arranged in the second groove 125, and the first end of the swinging member 132 is rotatably fixed at the vertex of the second groove 125, and the radius of the second groove 125 is equal to the length of the swinging member 132. The second groove 125 limits the swinging angle of the swinging member 132.

[0090] Specifically, the second groove 125 includes a first radial side 1251 and a second radial side 1252 , and the first radial side 1251 and the second radial side 1252 are two side edges of the fan-shaped second groove 125 .

[0091] An extension direction of the first radial side 1251 is parallel to an extension direction of the rotating rod 111 , and an angle is formed between the second radial side 1252 and the first radial side 1251 .

[0092] When the swinging member 132 abuts the second radial side 1252 in the second groove 125, the cover assembly 11 and the keyboard assembly 12 are in a closed state, and the sliding plate 1312 is located in the first groove 124. As the swinging member 132 swings from the second radial side 1252 toward the first radial side 1251, the cover assembly 11 rotates relative to the keyboard assembly 12, increasing the angle between the cover assembly 11 and the keyboard assembly 12. The swinging member 132 drives the sliding plate 1312 away from the first groove 124 in the first direction X. When the swinging member 132 abuts the first radial side 1251, the angle between the cover assembly 11 and the keyboard assembly 12 is maximized.

[0093] Specifically, due to the restriction of the first radial side 1251, the swinging member 132 cannot continue to swing in a direction away from the second radial side 1252. Therefore, the sliding plate 1312 cannot continue to move away from the first groove 124 in the first direction X. This is the maximum distance the sliding plate 1312 can move away from the first groove 124 in the first direction X. Furthermore, due to the restriction of the swinging member protrusion 1322 on the rotating rod 111 in the swinging member guide groove 1111 of the rotating rod 111, the rotating rod 111 cannot continue to rotate. In other words, the cover assembly 11 cannot continue to rotate relative to the keyboard assembly 12, causing the angle between the cover assembly 11 and the keyboard assembly 12 to continue to increase. At this point, the angle between the cover assembly 11 and the keyboard assembly 12 is at its maximum.

[0094] As described above, the sliding plate 1312 slides relative to the first groove 124 as the angle between the cover assembly 11 and the keyboard assembly 12 changes. That is, the cover assembly 11 is allowed to rotate relative to the keyboard assembly 12 at any angle less than or equal to the maximum angle, and the sliding plate 1312 slides accordingly, providing corresponding support for the cover assembly 11 and improving the safety of the cover assembly 11. This enables the foldable keyboard 1 to be placed at multiple angles, improving the user experience of the foldable keyboard.

[0095] The second groove 125 is used to limit the swing angle of the swing member 132 to prevent the angle between the cover assembly 11 and the keyboard assembly 12 from continuing to increase, and the sliding plate 1312 cannot provide a larger support area, which causes the folding keyboard 1 to tilt and over. This improves the safety of the folding keyboard 1 and enhances the user experience of the folding keyboard 1.

[0096] When the cover assembly 11 rotates relative to the keyboard assembly 12 and the swing member 132 rotates from the first radius side 1251 to the second radius side 1252, the angle between the cover assembly 11 and the keyboard assembly 12 becomes smaller, and when the swing member 132 swings in the second groove 125 to abut the second radius side 1252, the angle between the cover assembly 11 and the keyboard assembly 12 is the smallest, which is 0. At this time, the cover assembly 11 and the keyboard assembly 12 are in a closed state.

[0097] Optionally, the keyboard assembly 12 includes two second grooves 125, which are sequentially arranged at the bottom of the first groove 124 along the extension direction of the rotating rod 111, and the vertices of the two second grooves 125 are respectively arranged at two opposite end points in the first groove 124. In other words, the two second grooves 125 are symmetrically arranged with respect to the midline of the first groove 124.

[0098] The support assembly 13 includes two swinging members 132, each of which is disposed in a second groove 125. The second ends of the two swinging members 132 are connected to the sliding plate 1312. The two swinging members 132 jointly drive the sliding plate 1312 to slide, improving the stability and smoothness of the sliding plate 1312 during the sliding process, thereby improving the sliding efficiency of the sliding plate 1312.

[0099] In summary, in the folding keyboard 1 provided in the embodiment of the present application, the cover assembly 11 is used to place the mobile device 2, the keyboard assembly 12 is connected to the cover assembly 11, the first end of the support assembly 13 is connected to the cover assembly 11, and the second end of the support assembly 13 is connected to the keyboard assembly 12. Specifically, the swinging member 132 and the sliding plate 1312 of the support assembly 13 are arranged on the keyboard assembly 12. When the cover assembly 11 rotates relative to the keyboard assembly 12 and the angle between the cover assembly 11 and the keyboard assembly 12 is increased, the swinging member guide groove 1111 on the rotating rod 111 of the cover assembly 11 drives the swinging member 132 to swing, and then the swinging member 132 drives the sliding plate 1312 to move away from the keyboard assembly 12 along the first direction X, thereby increasing the support area of ​​the cover assembly 11. While ensuring that the cover assembly 11 does not tilt and over, the cover assembly 11 is allowed to be placed at multiple angles relative to the keyboard assembly 12, thereby improving the safety and practicality of the folding keyboard 1 and enhancing the user experience of the folding keyboard 1.

[0100] The present application also provides a folding device, as shown in Figures 7 and 8. Figure 7 is a schematic diagram of the structure of the first embodiment of the folding device of the present application, and Figure 8 is a schematic diagram of the structure of the second embodiment of the folding device of the present application. The folding device A provided in this embodiment of the present application includes a folding keyboard 1 and a mobile device 2.

[0101] The mobile device 2 can be detachably mounted on the cover assembly 11 of the foldable keyboard 1. In one embodiment, the mobile device 2 can be mounted on the cover assembly 11 by magnetic attraction to reduce the difficulty of mounting and removing the mobile device 2 from the cover assembly 11. In other embodiments, the mobile device 2 can also be mounted on the cover assembly 11 by other structures, and this application does not limit this.

[0102] As shown in Figure 7, when the cover assembly 11 rotates relative to the keyboard assembly 12, the support assembly 13 slides relative to the keyboard assembly 12 to support the cover assembly 11, thereby enabling the mobile device 2 to be placed at different angles, meeting the user's requirements for the placement angle of the mobile device 2, and improving the safety and practicality of the folding device A.

[0103] When the user closes the cover assembly 11 and the keyboard assembly 12, as shown in Figure 8, the support assembly 13 is then fitted with the cover assembly 11 and the keyboard assembly 12 to ensure the aesthetics of the folding device A and enhance the user's experience of using the folding device A.

[0104] Specifically, when the user needs to increase the placement angle of mobile device 2, the angle between cover assembly 11 and keyboard assembly 12 increases, causing the second end of support assembly 13 to move away from the second end of keyboard assembly 12 relative to keyboard assembly 12. Support assembly 13 is used to support cover assembly 11 and mobile device 2. Furthermore, as the placement angle of mobile device 2 increases, the support area of ​​support assembly 13 also increases, thereby improving the stability of foldable keyboard 1 supporting mobile device 2 and enhancing the safety of mobile device 2 when placed.

[0105] When the user reduces the placement angle of the mobile device 2, the angle between the cover assembly 11 and the keyboard assembly 12 decreases, and the second end of the support assembly 13 moves relative to the keyboard assembly 12 toward the second end of the keyboard assembly 12, thereby reducing the support area of ​​the support assembly 13 for the cover assembly 11 and the mobile device 2, reducing the space occupied by the support assembly 13, and ensuring the aesthetics of the folding device A.

[0106] The above description is only an implementation method of the present application and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the description and drawings of this application, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
