[0036] The technical solutions of the embodiments of this application 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 application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0037] Please refer to the attached document. Figures 1-7 This application provides a hinge assembly 100, which is applied to a keyboard and is used to prevent the support member 20 and the keyboard body 10 from falling backward.

[0038] Please refer to the attached document. Figures 1-7In this embodiment, the hinge assembly 100 includes a keyboard body 10, a support member 20, and a hinge module 30. The keyboard body 10 has a keyboard operation area 10a. The support member 20 is disposed on one side of the keyboard body 10 and is used to support electronic devices or protective cases. The hinge module 30 includes a first tube 31 and a second tube 32. The first tube 31 is connected to the keyboard body 10. The second tube 32 rotates relative to the first tube 31 and is connected to the support member 20. The support member 20 rotates with the rotation of the second tube 32 relative to the first tube 31 and is angled relative to the keyboard body 10. The second tube 32 is elongated and can be extended horizontally to increase the contact area between the second tube 32 and the keyboard body 10 and the table surface, avoiding only the keyboard body 10 contacting the table surface, preventing the support member 20 and the keyboard body 10 from tipping over, and preventing the hinge assembly 100 from tipping over.

[0039] Please refer to the attached document. Figures 1-7 In this embodiment of the application, the keyboard body 10 is provided with a keyboard operation area 10a; the keyboard operation area 10a is used for the user to operate the instructions and data of the electronic device.

[0040] The support member 20 is located on the rear side of the keyboard body 10. The support member 20 is rotatably connected to the keyboard body 10 so as to adjust the position of the support member 20 relative to the keyboard body 10. The support member 20 can cover or open the keyboard body 10. The support member 20 is used to support electronic devices or protective cases so that the electronic devices are arranged at an angle under the support of the support member 20, thereby avoiding the need for the user to support the electronic devices.

[0041] The hinge module 30 includes a first tube 31 and a second tube 32. The first tube 31 is connected to the keyboard body 10. The second tube 32 rotates relative to the first tube 31 to adjust the position of the second tube 32 relative to the first tube 31. The second tube 32 is connected to a support member 20. The support member 20 rotates with the rotation of the second tube 32 relative to the first tube 31 and adjusts its angle relative to the keyboard body 10. The second tube 32 is elongated and can be extended horizontally to increase the contact area between the second tube 32 and the keyboard body 10 and the table surface, avoiding only the keyboard body 10 contacting the table surface, preventing the support member 20 and the keyboard body 10 from tipping backward, and preventing the hinge assembly 100 from tipping backward.

[0042] In this embodiment, when the second tube 32 rotates relative to the first tube 31, the second tube 32 is adjusted from an up-down state to a horizontal state. The second tube 32 is arranged horizontally, with its long side extending along the width direction of the keyboard body 10 and its short side extending along the thickness direction of the keyboard body 10. This allows the long side of the second tube 32 and the width of the keyboard body 10 to simultaneously contact the table surface, thereby increasing the contact area between the second tube 32 and the keyboard body 10 relative to the table surface. This avoids only the keyboard body 10 contacting the table surface, preventing the support member 20 and the keyboard body 10 from tipping over, and preventing the hinge assembly 100 from tipping over.

[0043] Please refer to the attached document. Figures 1-7 In this embodiment, the lower surface of the long side of the second tube 32 faces the external table surface, and the lower surface of the long side of the second tube 32 can contact the external table surface, so that the lower surface of the long side of the second tube 32 and the lower surface of the keyboard body 10 can simultaneously contact the external table surface, thereby increasing the contact area between the second tube 32 and the keyboard body 10 and the table surface, avoiding only the keyboard body 10 contacting the table surface, preventing the support member 20 and the keyboard body 10 from falling backward, and preventing the hinge assembly 100 from falling backward.

[0044] Alternatively, there may be a gap between the lower surface of the long side of the second tube 32 and the external table surface, so that the long side of the second tube 32 can cushion the support 20 and the keyboard body 10 when they fall backward, preventing the support 20 and the keyboard body 10 from falling backward completely, thus avoiding the hinge assembly 100 from falling backward.

[0045] In this embodiment, a first support boss 321 is connected to the lower surface of the long side of the second tube 32. The lower surface of the first support boss 321 has a height difference or is flush with the lower surface of the long side of the second tube 32. The lower surface of the first support boss 321 is used to contact the external platform so that the keyboard body 10 can achieve a gap between the rear end of the keyboard body 10 and the external platform through the first support boss 321. This facilitates the keyboard body 10 to be arranged at an angle, thereby increasing the front end weight of the keyboard body 10, preventing the support member 20 and the keyboard body 10 from falling backward, and avoiding the hinge assembly 100 from falling backward.

[0046] Please refer to the attached document. Figures 1-7In this embodiment, the second tube 32 is provided with a second connecting arm 322, which is either a separate structure or an integrated structure with the support member 20. The second connecting arm 322 is located at the end of the second tube 32 away from the first tube 31. When the second connecting arm 322 and the support member 20 are an integrated structure, it increases the connection strength between the second connecting arm 322 and the support member 20, ensuring the connection stability between the second connecting arm 322 and the support member 20 and preventing the second connecting arm 322 from detaching from the support member 20 during use. When the second connecting arm 322 and the support member 20 are separate structures, it allows the support member 20 to be connected to or detached from the second connecting arm 322, thereby improving the ease of replacement of the support member 20.

[0047] The first tube 31 is provided with a first connecting arm 311, which is either a separate structure or an integrated structure with the keyboard body 10. The connection between the first tube 31 and the second tube 32 is located on the outside of the keyboard body 10. When the first connecting arm 311 and the keyboard body 10 are an integrated structure, it increases the connection strength between the first connecting arm 311 and the keyboard body 10, ensuring the connection stability between the first connecting arm 311 and the keyboard body 10 and preventing the first connecting arm 311 from detaching from the keyboard body 10 during use. When the first connecting arm 311 and the keyboard body 10 are separate structures, it allows the keyboard body 10 to be connected to or detached from the first connecting arm 311, thereby improving the ease of replacing the keyboard body 10.

[0048] Please refer to the attached document. Figures 1-7 In this embodiment, the first tube 31 is connected to the second tube 32. The connecting axis between the first tube 31 and the second tube 32 is close to the end of the second tube 32 facing the first tube 31. This arrangement concentrates the weight and force of the first tube 31 on one side of the second tube 32, making the force on the second tube 32 more concentrated and clear. This allows for better control during structural design and strength calculations, enabling targeted reinforcement of the structure of the first tube 31 and the second tube 32, and ensuring the reliability of the first tube 31 and the second tube 32.

[0049] Please refer to the attached document. Figures 1-7 In this embodiment of the application, a rotating member 33 is provided between the first tube 31 and the second tube 32, and the first tube 31 and the second tube 32 rotate relative to each other through the rotating member 33; the engaging part 331 of the rotating member 33 is engaged with the first tube 31, and the rotating part 332 of the rotating member 33 is fixedly connected to the second tube 32; so as to achieve the effect of rotation of the second tube 32 relative to the first tube 31.

[0050] Regarding the engagement connection between the engaging part 331 of the rotating component 33 and the first tube 31, the first tube 31 is provided with a flat end hole. The engaging part 331 of the rotating component 33 serves as the flat end. The engaging part 331 of the rotating component 33 is inserted into the flat end hole, and the rotating component 33 is fixedly connected to the first tube 31. The first tube 31 is fixedly connected to the keyboard body 10, and the first tube 31 is in a stationary state relative to the keyboard body 10.

[0051] Regarding the fixed connection between the rotating part 332 of the rotating member 33 and the second tube 32; the rotating part 332 of the rotating member 33 rotates relative to the engaging part 331 of the rotating member 33, and the rotating part 332 of the rotating member 33 engages with the second tube 32. The second tube 32 and the rotating part 332 of the rotating member 33 are relatively stationary. When the user folds the support member 20, the second tube 32 rotates relative to the first tube 31 as the support member 20 moves. The second tube 32 rotates because of the rotation of the rotating part 332 of the rotating member 33, thereby realizing the rotation of the second tube 32 relative to the first tube 31. Optionally, the rotating part 332 of the rotating member 33 is provided with a connecting arm, which is connected to the connecting groove of the second tube 32.

[0052] The axis of the rotating component 33 serves as the first axis; the connecting axis between the first tube 31 and the second tube 32 serves as the second axis, which coincides with or is adjacent to the first axis. When the second axis coincides with the first axis, the rotating component 33 can directly and without offset transmit power to the connection between the first tube 31 and the second tube 32 during rotation, avoiding power transmission losses caused by misalignment of the axes, such as additional friction and bending stress caused by eccentricity, thereby achieving more efficient power transmission. The rotation of the rotating component 33 ensures the rotation of the second tube 32 relative to the first tube 31.

[0053] When the second axis is arranged adjacent to the first axis, the force on the rotating shaft assembly 100 is more uniform and symmetrical. When subjected to external loads or internal pressure, the connection between the tube and the rotating component 33 can better resist deformation, reducing bending and torsional stress caused by torque, thereby enhancing the stability and load-bearing capacity of the rotating shaft assembly 100.

[0054] Please refer to the attached document. Figures 1-7In this embodiment, a damping element 34 is provided between the first tube 31 and the second tube 32. The damping element 34 is connected to the rotating member 33 and applies a rotational damping force to the rotating part 332 of the rotating member 33. This damping force increases the friction between the first tube 31 and the second tube 32, preventing the second tube 32 from rotating automatically relative to the first tube 31 and ensuring that the adjustment angle of the support member 20 relative to the keyboard body 10 remains unchanged. Optionally, the damping element 34 is a torsion spring, which is in a pre-tensioned state. Optionally, the damping element 34 is a torsion spring and is sleeved on the rotating member 33. One end of the damping element 34 is connected to the rotating part 332 of the rotating member 33, and the other end is connected to the engaging part 331 of the rotating member 33.

[0055] Please refer to the attached document. Figures 1-7 In this embodiment, the support member 20 includes a plurality of support portions 21. Two adjacent support portions 21 can swing relative to each other to adjust the position between the two adjacent support portions 21, thereby facilitating the swinging of the external device as one support portion 21 swings relative to another support portion 21. One support portion 21 is connected to the external device through a connector, so that the support member 20 can be connected to the external device through a support portion 21, thereby facilitating the support member 20 to support the external device and ensuring the placement angle of the external device.

[0056] The connector can be magnetic, adhesive, or magnetic. When the connector is magnetic, the external device is magnetically connected to the support 21. When the connector is adhesive, the external device is glued to the support 21. When the connector is magnetic, the external device is magnetically connected to the support 21.

[0057] In a second embodiment, a keyboard includes a hinge assembly 100, which is part of the keyboard and is used to operate instructions and data for an electronic device.

[0058] At this time, the hinge assembly 100 includes a keyboard body 10, a support member 20, and a hinge module 30; the keyboard body 10 is provided with a keyboard operation area 10a; the support member 20 is disposed on one side of the keyboard body 10 and is used to support electronic devices or protective cases; the hinge module 30 includes a first tube 31 and a second tube 32; the first tube 31 is connected to the keyboard body 10; the second tube 32 rotates relative to the first tube 31 and is connected to the support member 20; the support member 20 rotates with the rotation of the second tube 32 relative to the first tube 31 and is angled relative to the keyboard body 10; the second tube 32 is elongated and can be extended horizontally to increase the contact area between the second tube 32 and the keyboard body 10 and the table surface, avoiding only the keyboard body 10 contacting the table surface, preventing the support member 20 and the keyboard body 10 from tipping backward, and preventing the hinge assembly 100 from tipping backward.
