Description

Technical Field

[0001] The present application relates to the technical field of keyboard folding, and particularly to a folding keyboard and a folding bracket. Background Art

[0002] With the rapid development of society, people's living standards have been continuously improved, and electronic products have become necessities in people's lives. There are various types of electronic products, including tablet devices. To facilitate people's better use of tablets, merchants have invented some tablet supporting components, including Bluetooth keyboard folding brackets.

[0003] The existing Bluetooth keyboard folding brackets have certain drawbacks when in use. Since the tablet bracket is directly placed obliquely during use, and the weight of the tablet is greater than that of the keyboard, the placement is unstable and the bracket is prone to warping and tipping over. When the user operates the tablet, it is also easy to cause the tablet and the Bluetooth keyboard folding bracket to tip over. At the same time, in order to achieve multi-angle placement of the tablet, some folding brackets use a multi-fold structure, which occupies the area of the keyboard, resulting in the keyboard area not being able to be laid out maximally and affecting the user's key pressing experience.

[0052] Please refer to Figure 1 , Figure 1 is a schematic structural diagram of the first embodiment of the folding keyboard of this application. The folding keyboard 1 provided in the embodiment of this application is applied to a mobile device 2, where the mobile device can be a tablet computer, a mobile phone, etc. The folding keyboard 1 includes a cover plate assembly 11, a keyboard assembly 12, and a support assembly 13.

[0053] Among them, the cover plate assembly 11 is used to place the mobile device 2. The first end of the keyboard assembly 12 is rotatably connected to the cover plate assembly and includes a keyboard 121, and the keyboard 121 is connected to the mobile device 2. The first end of the support assembly 13 is connected to the cover plate assembly 11, and the second end of the support assembly 13 is slidably connected to the keyboard assembly 12.

[0054] Specifically, when the cover plate assembly 11 and the keyboard assembly 12 are in an open state, that is, there is an included angle between the cover plate 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 first end of the keyboard assembly 12, and the support assembly 13 is used to support the cover plate assembly 11. Among them, the first end and the second end of the keyboard assembly 12 are two opposite ends on the keyboard assembly 12.

[0055] When the cover plate assembly 11 and the keyboard assembly 12 are in the open state, that is, there is an included angle between the cover plate assembly 11 and the keyboard assembly 12, and the cover plate assembly 11 rotates relative to the keyboard assembly 12 to increase the included angle between the cover plate assembly 11 and the keyboard assembly 12, the support assembly 13 moves relative to the keyboard assembly 12 in a direction away from the second end of the keyboard assembly 12 to increase the support area for the cover plate assembly 11, avoiding the situation that the cover plate assembly 11 tilts and overturns due to an excessive included angle between the cover plate assembly 11 and the keyboard assembly 12, improving the safety of the folding keyboard 1 and enhancing the user experience of the folding keyboard 1.

[0056] At the same time, when the cover plate assembly 11 rotates relative to the keyboard assembly 12 to reduce the included angle between the cover plate 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 close to the second end of the keyboard assembly 12, reducing the occupied space of the folding keyboard 1 when the cover plate assembly 11 and the keyboard assembly 12 are in the closed state (the included angle between the cover plate assembly 11 and the keyboard assembly 12 is 0) and ensuring the aesthetics of the folding keyboard 1.

[0057] It can be understood that during the rotation of the cover plate assembly 11 relative to the keyboard assembly 12, when the included angle between the cover plate assembly 11 and the keyboard assembly 12 changes, the support assembly 13 slides as the included angle between the cover plate assembly 11 and the keyboard assembly 12 changes.

[0058] In one embodiment, please refer to Figure 1 and Figure 2 , Figure 2 which is a schematic structural diagram of the second embodiment of the folding keyboard of the present application. When the cover plate assembly 11 rotates relative to the keyboard assembly 12 and the included angle between the cover plate 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, increasing the support area for the cover plate assembly 11.

[0059] In another embodiment, when the included angle between the cover plate assembly 11 and the keyboard assembly 12 decreases and the cover plate assembly 11 and the keyboard assembly 12 are about to close, as the included angle between the cover plate assembly 11 and the keyboard assembly 12 becomes smaller, the support assembly 13 slides relative to the keyboard assembly 12 in a direction close to the second end of the keyboard assembly 12. That is, the support assembly 13 slides as the included angle between the cover plate assembly 11 and the keyboard assembly 12 changes, and the support assembly 13 increases or decreases the support area for the cover plate assembly 11 as the included angle between the cover plate assembly 11 and the keyboard assembly 12 increases or decreases, improving the flexibility of the support assembly 13.

[0060] Optionally, please refer to Figure 3 , Figure 3It is a schematic structural diagram of the third embodiment of the folding keyboard of the present application. The support assembly 13 includes a support member 131 and a swing member 132.

[0061] One end of the support member 131 is connected to the cover plate 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 slidably connected to the keyboard assembly 12 through the swing member 132.

[0062] Specifically, during the process of the cover plate assembly 11 rotating relative to the keyboard assembly 12, when the included angle between the cover plate assembly 11 and the keyboard assembly 12 increases, the swing member 132 swings with the connection point between the swing member 132 and the keyboard assembly 12 as the rotation center, so as to drive 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.

[0063] Optionally, please refer to Figure 4 , Figure 4 It is a schematic structural diagram of the fourth embodiment of the folding keyboard of the present application. The support member 131 includes a connecting belt 1311 and a sliding plate 1312.

[0064] One end of the connecting belt 1311 is connected to the cover plate 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.

[0065] During the process of the cover plate assembly 11 rotating relative to the keyboard assembly 12, when the included angle between the cover plate assembly 11 and the keyboard assembly 12 increases, the swing member 132 swings, so as 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 contracts.

[0066] In one embodiment, the connecting belt 1311 is elastic. Among them, the connecting belt 1311 can be an elastic elastic band or an elastic cord. Furthermore, during the process of the cover plate assembly 11 rotating relative to the keyboard assembly 12, when the included angle between the cover plate 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 Figure 1 shown, when the included angle between the cover plate 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 plate assembly 11 and the sliding plate 1312 becomes smaller, then the connecting belt 1311 will accumulate between the cover plate assembly 11 and the sliding plate 1312, affecting the aesthetics of the folding keyboard 1.

[0067] In this embodiment, the connecting belt 1311 is elastic. Thus, when the distance between the cover plate assembly 11 and the sliding plate 1312 decreases, the connecting belt 1311 contracts, improving the aesthetics of the folding keyboard 1. When the cover plate assembly 11 and the keyboard assembly 12 are in the closed state, the connecting belt 1311 can cover the cover plate assembly 11, shielding the connection between the cover plate assembly 11 and the keyboard assembly 12 and further enhancing the aesthetics of the folding keyboard 1.

[0068] Optionally, please refer to Figure 4 and Figure 5 , Figure 5 which Figure 4 is a schematic structural view of a part of the folding keyboard in

[0069] The support assembly 13 includes a sliding member 133. The second end of the swinging member 132 has a guiding groove 1321. One end of the sliding member 133 is disposed in the guiding groove 1321, and the other end of the sliding member 133 is connected to the sliding plate 1312.

[0070] During the swinging of the swinging member 132, one end of the sliding member 133 slides in the guiding groove 1321 to drive the sliding plate 1312 to slide along the first direction X, where the first direction X is perpendicular to the end face of the first end of the keyboard assembly 12, that is, the first direction X is parallel to the normal direction of the end face of the first end of the keyboard assembly 12. Among them, when the sliding plate 1312 slides along the first direction X, compared with the sliding of the sliding plate 1312 in other directions, the sliding efficiency of the sliding plate 1312 sliding away from the second end of the keyboard assembly 12 is higher, and the sliding plate 1312 can quickly increase the supporting area for the cover plate assembly 11, improving the sliding efficiency of the sliding plate 1312.

[0070] Specifically, when the cover plate assembly 11 rotates relative to the keyboard assembly 12 and the included angle between the cover plate assembly 11 and the keyboard assembly 12 increases, the swinging member 132 swings, and one end of the sliding member 133 slides in the guiding groove 1321, restricting the sliding direction of the sliding plate 1312 so that the sliding plate 1312 slides along the first direction X away from the second end of the keyboard assembly 12.

[0071] Optionally, please refer to Figure 3 , Figure 5 and Figure 6 , Figure 6 which is a schematic structural view of the first embodiment of the cover plate assembly of the present application. One end of the cover plate assembly 11 includes a rotating rod 111, and the first end of the keyboard assembly 12 includes two fixing members 122. The cover plate assembly 11 and the keyboard assembly 12 are rotatably connected through the rotating rod 111 and the fixing members 122.

[0072] Among them, two fixing members 122 are respectively rotatably connected to both ends of the rotating rod 111. In one embodiment, the fixing member 122 is a hollow structure with an accommodating cavity. The folding keyboard 1 further includes a fixed rotating shaft disposed in the accommodating cavity of the fixing member 122 and connected to the rotating rod 111, so as to realize the rotational connection between the cover plate assembly 11 and the keyboard assembly 12 through 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 through a snap structure. The present application does not limit the specific form of connecting the fixing member 122 and the rotating rod 111 to realize the rotational connection between the cover plate assembly 11 and the keyboard assembly 12.

[0073] In one embodiment, the fixing member 122 may include an extension member. The extending direction of the extension member is the direction from the fixing member 122 to the rotating rod 111. Furthermore, the extension member shields the rotating rod 111, improving the aesthetics of the folding keyboard 1.

[0074] Furthermore, the rod body of the rotating rod 111 has a swing member guide groove 1111, and the swing member guide groove 1111 is arranged in a direction away from the end face of the rotating rod 111. The first end of the swing member 132 has a swing member convex shaft 1322, and the swing member convex shaft 1322 is arranged in the swing member guide groove 1111.

[0075] When the cover plate assembly 11 rotates relative to the keyboard assembly 12 and the included angle between the cover plate assembly 11 and the keyboard assembly 12 changes, the rotating rod 111 rotates relative to the fixing member 122. Furthermore, the swing member guide groove 1111 follows the rotation of the rotating rod 111, and the swing member convex shaft 1322 moves in the swing member guide groove 1111 to drive the swing member 132 to swing.

[0076] Specifically, since the rotating rod 111 is arranged on the cover plate assembly 11, when the cover plate assembly 11 rotates relative to the keyboard assembly 12, the rotating rod 111 will rotate accordingly, and the swing member guide groove 1111 rotates therewith. Since the first end of the swing member 132 is fixed to the keyboard assembly 12 and the swing member convex shaft 1322 at the first end of the swing member 132 is arranged in the swing member guide groove 1111, the swing member 132 is driven to swing with the connection point between the swing member 132 and the keyboard assembly 12 as the rotation center. Furthermore, the swing of the swing member 132 drives the sliding plate 1312 to slide along the first direction X, realizing the sliding of the sliding plate 1312 as the included angle between the cover plate assembly 11 and the keyboard assembly 12 changes, improving the flexibility of the sliding of the sliding plate 1312.

[0077] Optionally, please continue to refer to Figure 4 and Figure 5, the keyboard assembly 12 includes a housing 123. The keyboard 121 is disposed on the first surface of the housing 123, and the support assembly 13 is disposed on the second surface of the housing 123. The first surface and the second surface are two 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, and the support assembly 13 is disposed on the back surface of the housing 123. The housing 123 shields the support assembly 13, improving the aesthetics of the folding keyboard 1.

[0078] Wherein, 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 one end of the housing 123 close to the rotating rod 111.

[0079] The sliding plate 1312 and the swing member 132 are disposed in the first groove 124. The sliding plate 1312 is connected to the bottom of the first groove 124 through the swing member 132. Specifically, the first end of the swing member 132 is connected to the bottom of the first groove 124. When the swing member 132 swings, the sliding plate 1312 slides out of the first groove 124 along the first direction X to support the cover plate assembly 11. When the cover plate assembly 11 rotates relative to the keyboard assembly 12 and the included angle between the cover plate assembly 11 and the keyboard assembly 12 becomes smaller, the sliding plate 1312 slides back into the first groove 124. The first groove 124 accommodates the sliding plate 1312, reducing the occupied space of the folding keyboard 1 and ensuring the aesthetics of the folding keyboard 1.

[0080] At the same time, since the connecting belt 1311 is connected to one end of the sliding plate 1312, when the cover plate 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 shield the connection between the cover plate 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 enhancing the user experience of the folding keyboard 1.

[0081] Optionally, as Figure 5 shown, 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.

[0082] Wherein, the swing member 132 is disposed in the second groove 125, and the first end of the swing 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 swing member 132. The second groove 125 limits the swing angle of the swing member 132.

[0083] Specifically, the second groove 125 includes a first radius side 1251 and a second radius side 1252. The first radius side 1251 and the second radius side 1252 are two sides of the sector-shaped second groove 125.

[0084] The extending direction of the first radius side 1251 is parallel to the extending direction of the rotating rod 111, and an included angle is formed between the second radius side 1252 and the first radius side 1251.

[0085] When the swinging member 132 abuts against the second radius side 1252 in the second groove 125, the cover plate assembly 11 and the keyboard assembly 12 are in a closed state, and the sliding plate 1312 is located in the first groove 124. When the swinging member 132 swings from the second radius side 1252 to the first radius side 1251, the cover plate assembly 11 rotates relative to the keyboard assembly 12, and the included angle between the cover plate assembly 11 and the keyboard assembly 12 increases. The swinging member 132 drives the sliding plate 1312 to move away from the first groove 124 along the first direction X. When the swinging member 132 abuts against the first radius side 1251, the included angle between the cover plate assembly 11 and the keyboard assembly 12 is the largest.

[0086] Specifically, due to the limitation of the first radius side 1251, the swinging member 132 cannot continue to swing in the direction away from the second radius side 1252. Therefore, the sliding plate 1312 cannot continue to move away from the first groove 124 along the first direction X. At this time, it is the maximum distance for the sliding plate 1312 to move away from the first groove 124 along the first direction X. And due to the limitation of the swinging member convex shaft 1322 of the swinging member 132 on the rotating rod 111 in the swinging member guiding groove 1111 of the rotating rod 111, the rotating rod 111 cannot continue to rotate. That is, the cover plate assembly 11 cannot continue to rotate relative to the keyboard assembly 12, so that the included angle between the cover plate assembly 11 and the keyboard assembly 12 continues to increase. Then, at this time, the included angle between the cover plate assembly 11 and the keyboard assembly 12 is the largest.

[0087] As described above, the sliding plate 1312 slides relative to the first groove 124 as the included angle between the cover plate assembly 11 and the keyboard assembly 12 changes. That is, the cover plate assembly 11 is allowed to rotate relative to the keyboard assembly 12 at any angle less than or equal to the maximum included angle, and the sliding plate 1312 slides accordingly, providing corresponding support force for the cover plate assembly 11 and improving the safety of the cover plate assembly 11. The folding keyboard 1 can be placed at multiple angles, improving the user experience of the folding keyboard.

[0088] By restricting the swinging angle of the swinging member 132 through the second groove 125, it is avoided that the included angle between the cover plate assembly 11 and the keyboard assembly 12 continues to increase, while the sliding plate 1312 cannot provide a larger supporting area, resulting in the situation that the folding keyboard 1 tilts and topples over, improving the safety of the folding keyboard 1 and the user experience of the folding keyboard 1.

[0089] When the cover plate assembly 11 rotates relative to the keyboard assembly 12 and the swing member 132 rotates from the first radius side 1251 towards the second radius side 1252, the angle between the cover plate assembly 11 and the keyboard assembly 12 becomes smaller. When the swing member 132 swings in the second groove 125 and abuts against the second radius side 1252, the angle between the cover plate assembly 11 and the keyboard assembly 12 is minimized to 0. At this time, the cover plate assembly 11 and the keyboard assembly 12 are in a closed state.

[0090] 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 endpoints within the first groove 124. That is to say, the two second grooves 125 are symmetrically arranged with respect to the midline of the first groove 124.

[0091] The support assembly 13 includes two swing members 132, each swing member 132 is arranged within one second groove 125, and the second ends of the two swing members 132 are connected to the sliding plate 1312. The two swing members 132 jointly drive a sliding plate 1312 to slide, improving the smoothness and fluency of the sliding plate 1312 during the sliding process and enhancing the sliding efficiency of the sliding plate 1312.

[0092] In summary, in the folding keyboard 1 provided by the embodiment of the present application, the cover plate assembly 11 is used to place the mobile device 2, the keyboard assembly 12 is connected to the cover plate assembly 11, the first end of the support assembly 13 is connected to the cover plate assembly 11, and the second end of the support assembly 13 is connected to the keyboard assembly 12. Specifically, the swing member 132 and the sliding plate 1312 of the support assembly 13 are arranged on the keyboard assembly 12. When the cover plate assembly 11 rotates relative to the keyboard assembly 12 and the angle between the cover plate assembly 11 and the keyboard assembly 12 is increased, the swing member guiding groove 1111 on the rotating rod 111 of the cover plate assembly 11 drives the swing member 132 to swing. Then, the swing member 132 drives the sliding plate 1312 to move away from the keyboard assembly 12 along the first direction X, increasing the support area for the cover plate assembly 11. While ensuring that the cover plate assembly 11 does not tilt or tip over, it allows the cover plate assembly 11 to be placed at multiple angles relative to the keyboard assembly 12, improving the safety and practicality of the folding keyboard 1 and enhancing the user experience of the folding keyboard 1.

[0093] The present application also provides a folding device. Please refer to Figure 7 and Figure 8 , Figure 7 which is a schematic structural diagram of the first embodiment of the folding device of the present application. Figure 8It is a schematic structural diagram of the second embodiment of the folding device of the present application. The folding device A provided by the embodiment of the present application includes a folding keyboard 1 and a mobile device 2.

[0094] The mobile device 2 is detachably arranged on the cover plate assembly 11 of the folding keyboard 1. In one embodiment, the mobile device 2 can be arranged on the cover plate assembly 11 in a magnetic attraction form to reduce the loading and unloading difficulty of the mobile device 2 on the cover plate assembly 11. In other embodiments, the mobile device 2 can also be arranged on the cover plate assembly 11 through other structures, and the present application does not limit this.

[0095] As Figure 7 shown, when the cover plate assembly 11 rotates relative to the keyboard assembly 12, the support assembly 13 slides relative to the keyboard assembly 12 to support the cover plate assembly 11, so that the mobile device 2 can be placed at different angles, meeting the user's requirements for the placement angle of the mobile device 2 and improving the safety and practicability of the folding device A.

[0096] When the user closes the cover plate assembly 11 and the keyboard assembly 12, as Figure 8 shown, the support assembly 13 is attached to the cover plate assembly 11 and the keyboard assembly 12 accordingly to ensure the aesthetics of the folding device A and improve the user experience of the folding device A.

[0097] The above is only the implementation mode of the present application, and does not limit the patent scope of the present application accordingly. Any equivalent structure or equivalent process transformation made by using the specification and drawings of the present application, or directly or indirectly applied to other related technical fields, shall be included in the patent protection scope of the present application by the same token.
