Among them, a limiting convex is provided on the connecting member, and the limiting convex of the two connecting members connected is correspondingly provided, so that during the rotation of the first connecting plate relative to the second connecting plate, they can abut against each other to limit the rotation range between the first connecting plate and the second connecting plate, so the rotation range of the first connecting plate relative to the second connecting plate is 0° to 120°. Therefore, in actual use, the user can adjust the relative angle and position between the first connecting plate and the second connecting plate by adjusting the second rotating assembly to achieve control of the angle and position of the tablet computer. At the same time, the relative position and angle between the connecting plate assembly and the keyboard plate assembly can also be controlled by adjusting the first rotating assembly. Therefore, in actual use, the user can freely combine the rotation range of the first rotating assembly and the rotation range of the second rotating assembly according to personal needs to form a variety of usage states. For example: when the first connecting plate is rotated 45 degrees relative to the second connecting plate, and the second connecting plate is rotated 90 degrees relative to the keyboard plate in the first state, the first connecting plate and the second connecting plate remain coplanar, and the second connecting plate is rotated 120 degrees relative to the keyboard plate in the second state, and the first connecting plate and the second connecting plate remain coplanar, and the second connecting plate is set parallel to the keyboard plate in the third state.The above setting method is convenient for users to adjust the tablet computer to the position and angle they need, so as to meet different usage scenarios and needs of users and facilitate user operation. To a certain extent, it enriches the usage of the protective cover with keyboard and improves the usage flexibility and application scope of the protective cover with keyboard.

[0039] The embodiment of the present invention provides a protective cover 1000 with a keyboard, such as Figure 1-6As shown, the protective cover 1000 with a keyboard includes: a keyboard plate assembly 100, a connecting plate assembly 200, a first rotating assembly 300 and a second rotating assembly 400, the keyboard plate assembly 100 includes a keyboard plate 101 and two fixing members 102 arranged on one side of the keyboard plate 101, and the two fixing members 102 are arranged opposite to each other on the same side; the connecting plate assembly 200 includes a first connecting plate 201 and a second connecting plate 202 that are rotatably connected, and a rotating member 203 arranged on a side of the second connecting plate 202 away from the first connecting plate 201, and the opposite ends of the rotating member 203 are rotatably connected to the two fixing members 102 respectively; the rotating member 203 and the fixing member 102 are rotatably connected through the first rotating assembly 300 The first rotating assembly 300 includes a rotating shaft 301 and a damping member 302. One end of the rotating shaft 301 is engaged with the rotating member 203, and the other end is rotatably connected to the damping member 302. The damping member 302 is engaged with the fixed member 102. The damping member 302 abuts against the rotating member 203 through the rotating shaft 301, so that the rotating member 203 has a damping force during the rotation process relative to the fixed member 102. The rotating shaft 301 is provided with a first stopper 3011, and the damping member 302 is provided with a second stopper 3021. The first stopper 3011 can abut against the second stopper 3021 during the rotation of the rotating shaft 301 relative to the damping member 302, so as to limit the second connecting plate 202 from rotating relative to the keyboard plate 1 01 has a rotation range of 0° to 150°; the first connecting plate 201 and the second connecting plate 202 are rotatably connected through the second rotating assembly 400, and the second rotating assembly 400 includes a rotating rod 401 and a plurality of connecting members 402, the connecting members 402 are arranged on the side of the first connecting plate 201 facing the second connecting plate 202, and on the side of the second connecting plate 202 facing the rotating member 203, the rotating rod 401 passes through the plurality of connecting members 402 in sequence, and is rotatably connected with the connecting members 402, and a limiting protrusion 40211 is provided on the connecting member 402, and the limiting protrusions 40211 of two adjacent connecting members 402 are correspondingly arranged, wherein one limiting protrusion 40211 can be relative to the second connecting member on the first connecting plate 201 During the rotation of the plate 202, it abuts against another limiting protrusion 40211 to limit the rotation range of the first connecting plate 201 relative to the second connecting plate 202 to 0° to 120°; wherein, the protective cover 1000 with a keyboard has a first state when the first connecting plate 201 is rotated 45 degrees relative to the second connecting plate 202, and the second connecting plate 202 is rotated 90° relative to the keyboard plate 101, a second state in which the first connecting plate 201 and the second connecting plate 202 remain coplanar, and the second connecting plate 202 is rotated 120° relative to the keyboard plate 101, and a third state in which the first connecting plate 201 and the second connecting plate 202 remain coplanar, and the second connecting plate 202 is arranged parallel to the keyboard plate 101.

[0040] The connecting plate assembly 200 and the keyboard plate assembly 100 are rotatably connected through the first rotating assembly 300, so as to facilitate the user to operate the tablet computer through the keyboard. The first rotating assembly 300 is arranged between the rotating member 203 in the connecting plate assembly 200 and the two fixed members 102 in the keyboard plate assembly 100, so as to realize the rotation of the rotating member 203 relative to the two fixed members 102. Among them, one end of the rotating shaft 301 is engaged and connected with the rotating member 203, and the other end is rotatably connected with the damping member 302 sleeve, and the damping member 302 is engaged and connected with the fixed member 102, so when the rotating shaft 301 rotates relative to the damping member 302, the damping member 302 will not rotate with the rotating shaft 301, and can drive the rotating member 203 at the other end of the rotating shaft 301 to rotate together, so as to ensure that the rotation relationship between the rotating member 203 and the fixed member 102 is realized. At the same time, the friction between the rotating shaft 301 and the rotating member 203 is increased because the damping member 302 abuts against the rotating member 203 through the rotating shaft 301, thereby providing a damping force when the rotating shaft 301 drives the rotating member 203 to rotate, so that the rotating member 203 can be relatively fixed at a desired position during the relative rotation with the fixed member 102. A first stopper 3011 is provided on the rotating shaft 301, which is used to cooperate with a second stopper 3021 on the damping member 302 to limit the rotation range of the rotating shaft 301. During the rotation of the rotating shaft 301 relative to the damping member 302, the first stopper 3011 can abut against the second stopper 3021, thereby playing the role of stopping the rotating shaft 301 to limit the rotation range of the rotating shaft 301, and when adjusted to the desired position, the tablet computer and the connecting plate assembly 200 can remain fixed relative to the keyboard plate assembly 100, so the rotation range of the second connecting plate 202 relative to the keyboard plate 101 is limited to 0° to 150°. The first connecting plate 201 and the second connecting plate 202 in the connecting plate assembly 200 can be rotatably connected through the second rotating assembly 400, and the connecting rod passes through a plurality of connecting members 402 in sequence to rotatably connect the first connecting plate 201 and the second connecting plate 202. Among them, a limiting protrusion 40211 is provided on the connecting member 402, and the limiting protrusions 40211 of two adjacent connecting members 402 are correspondingly provided, so that they can counteract each other during the rotation of the first connecting plate 201 relative to the second connecting plate 202 to limit the rotation range between the first connecting plate 201 and the second connecting plate 202, so that the rotation range of the first connecting plate 201 relative to the second connecting plate 202 is 0° to 120°. Therefore, in actual use, the user can adjust the relative angle and position between the first connecting plate 201 and the second connecting plate 202 by adjusting the second rotating assembly 400 to achieve control of the angle and position of the tablet computer. At the same time, the relative position and angle between the connecting plate assembly 200 and the keyboard plate assembly 100 can also be controlled by adjusting the first rotating assembly 300.Therefore, in actual use, users can freely combine the rotation range of the first rotating component 300 and the rotation range of the second rotating component 400 according to personal needs to form a variety of usage states. For example: when the first connecting plate 201 rotates 45° relative to the second connecting plate 202, and the second connecting plate 202 rotates 90° relative to the keyboard plate 101 in the first state, the first connecting plate 201 and the second connecting plate 202 remain coplanar, and the second connecting plate 202 rotates 120° relative to the keyboard plate 101 in the second state, and the first connecting plate 201 and the second connecting plate 202 remain coplanar, and the second connecting plate 202 is arranged parallel to the keyboard plate 101 in the third state. The above setting method is convenient for users to adjust the tablet computer to the position and angle they need, so as to meet different usage scenarios and needs of users and facilitate user operation. To a certain extent, the usage of the protective cover 1000 with a keyboard is enriched, and the usage flexibility and application scope of the protective cover 1000 with a keyboard are improved.

[0041] Specifically, the rotating member 203 is connected to the second connecting plate 202, the fixing member 102 is connected to the keyboard plate 101, and the rotating member 203 and the fixing member 102 are rotatably connected through the first rotating assembly 300, so the connecting plate assembly 200 can rotate relative to the keyboard plate assembly 100. The first connecting plate 201 and the second connecting plate 202 are rotatably connected through the second rotating assembly 400. One end of the rotating shaft 301 is engaged and connected with the rotating member 203, and the other end is rotatably connected with the damping member 302, so as to ensure the stability of the rotatable connection between the keyboard plate assembly 100 and the connecting plate assembly 200.

[0042] Specifically, the damping member 302 in the first rotating assembly 300 abuts against the rotating member 203 through the rotating shaft 301, so that the friction between the damping member 302 and the rotating member 203 is increased, thereby providing a damping effect when the rotating member 203 rotates relative to the fixed member 102, so that the rotating shaft 301 is limited to stay at a certain position during the rotation of the rotating shaft 301 relative to the damping member 302. This prevents the rotating shaft 301 from suddenly moving or shaking relative to the damping member 302, thereby improving the stability of the first rotating assembly 300 during rotation. The first stop portion 3011 and the second stop portion 3021 cooperate with each other to limit the rotation range of the rotating shaft 301, ensuring that the connecting plate assembly 200 moves within a preset angle range. The limiting protrusion 40211 on the connecting member 402 can limit the rotation range of the second rotating assembly 400, so that the first connecting plate 201 and the second connecting plate 202 can rotate within a preset range, avoiding excessive rotation or incomplete rotation of the connecting plate assembly 200 relative to the keyboard plate assembly 100, and between the first connecting plate 201 and the second connecting plate 202.

[0043] refer to Figure 2 and Figure 5The connecting member 402 includes a rotating sleeve 4021 and a mounting plate 4022 connected to each other. A plurality of mounting grooves 2011 are respectively provided on the opposite sides of the first connecting plate 201 and the second connecting plate 202. The mounting plate 4022 is disposed in the mounting groove 2011. The rotating shaft 301 is rotatably connected to the rotating sleeve 4021. A limiting protrusion 40211 is disposed on the rotating sleeve 4021.

[0044] The rotating rod 401 is rotatably connected to the rotating sleeve 4021, and the first connecting plate 201 and the second connecting plate 202 are rotatably connected to the rotating rod 401 through the rotating sleeve 4021. The connecting member 402 is fixedly connected to the mounting groove 2011 on the first connecting plate 201 and the mounting groove 2011 on the second connecting plate 202 through the mounting piece 4022, respectively, to ensure that the connection of the connecting member 402 to the first connecting plate 201 and the second connecting plate 202 is firmly connected. At the same time, the first connecting plate 201 and the second connecting plate 202 are rotatably connected to the rotating rod 401 through the connecting member 402, so that the first connecting plate 201 and the second connecting plate 202 are prevented from directly contacting the rotating rod 401, and the wear and scratch caused by the long-term rotational connection between the first connecting plate 201 and the second connecting plate 202 and the rotating rod 401 are avoided, thereby improving the durability and service life of the connecting plate assembly 200.

[0045] Specifically, the mounting plate 4022 is connected to the mounting groove 2011 of the first connecting plate 201, and the mounting plate is connected to the mounting groove 2011 of the second connecting plate 202, which can increase the connection area between the connecting member 402 and the first connecting plate 201 or the second connecting plate 202, and can reduce the possibility of the connecting member 402 loosening or falling off, thereby ensuring the stability and reliability of the connecting plate assembly 200, and helping to improve the reliability of the protective cover 1000 with a keyboard.

[0046] Specifically, the limiting protrusion 40211 is disposed on the rotating sleeve 4021 , so when the two connected connecting members 402 rotate relative to each other, the corresponding two adjacent limiting protrusions 40211 can offset each other due to the rotation to limit the rotation range between the first connecting plate 201 and the second connecting plate 202 .

[0048] A nut 304 is fixedly connected to one end of the rotating shaft 301 extending from the damping member 302. The nut 304 has the effect of tightening and limiting the damping member 302, so as to prevent the rotating shaft 301 from loosening or shaking relative to the damping member 302 or even slipping out of the damping member 302 during the rotation of the rotating shaft 301 relative to the damping member 302, so as to improve the stability of the first rotating assembly 300. A pressing gasket 303 is provided between the nut 304 and the damping member 302, and the two ends of the pressing gasket 303 are respectively against the damping member 302 and the nut 304. The pressing gasket 303 can apply pressure to the damping member 302 and the nut 304 respectively, so that the structural strength of the entire first rotating assembly 300 is higher, and the connection between the various components of the first rotating assembly 300 can be ensured to be more stable. In actual use, one end of the rotating shaft 301 is engaged with the rotating member 203 through the first engaging hole 2033 , and the other end is rotatably connected to the damping member 302 , and the damping member 302 is engaged with the fixing member 102 through the second engaging hole 1023 . After the two ends of the rotating shaft 301 are respectively connected to the rotating member 203 and the fixed member 102, since the position of the nut 304 relative to the rotating shaft 301 is fixed, the force of the clamping gasket 303 on the nut 304 will react to the clamping gasket 303 itself. At the same time, the supporting force of the clamping gasket 303 on the damping member 302 and the reaction force of the nut 304 on the clamping gasket 303 can force the damping member 302 to be pressed toward the rotating member 203, so that the supporting effect between the damping member 302 and the rotating member 203 is tighter, thereby increasing the friction between the damping member 302 and the rotating member 203, and finally achieving the damping effect during the relative rotation of the rotating member 203 and the fixed member 102.

[0049] Specifically, the compression gasket 303 can increase the pressure of the damping member 302, further enhance the damping effect of the damping member 302, make the rotation process more stable, avoid the sudden movement or shaking of the rotating member 203, and improve the stability and user experience of the protective cover with keyboard.

[0050] Specifically, the rotational connection design between the rotating shaft 301 and the clamping gasket 303 can make the rotation process of the rotating shaft 301 smoother, reduce unnecessary friction, improve the smoothness of the rotation of the rotating shaft 301, and make it more convenient for users to operate the protective cover 1000 with a keyboard.

[0051] Specifically, in actual use, the pressure of the compression gasket 303 can be adjusted by adjusting the position of the nut 304 on the rotating shaft 301, so as to adjust the pressure of the damping member 302, and finally achieve precise control of the damping force during rotation, meet the different usage requirements of users, and improve the flexibility and applicability of the protective cover 1000 with a keyboard.

[0052] refer to Figures 8 to 11 A first positioning surface 3022 is provided on the damping member 302, a second positioning surface 10231 corresponding to the first positioning surface 3022 is provided in the second engaging hole 1023, a third positioning surface 3012 is provided on the side of the rotating shaft 301 facing the first engaging hole 2033, a fourth positioning surface 20331 corresponding to the third positioning surface 3012 is provided in the first engaging hole 2033, the first positioning surface 3022 is in contact with the second positioning surface 10231, and the second positioning surface 10231 is in contact with the fourth positioning surface 20331.

[0053] A first positioning surface 3022 is provided on the damping member 302, and a second positioning surface 10231 corresponding to the first positioning surface 3022 is provided on the inner wall of the second engaging hole 1023, so that the damping member 302 is engaged and connected with the second engaging hole 1023, so that when the rotating shaft 301 rotates relative to the damping member 302, the damping member 302 can maintain a fixed relative position with the fixing member 102 without rotating with the rotating shaft 301 due to the abutment between the first positioning surface 3022 and the second positioning surface 10231. A third positioning surface 3012 is provided on the side of the rotating shaft 301 facing the first engaging hole 2033, and a fourth positioning surface 20331 corresponding to the third positioning surface 3012 is provided on the inner wall of the first engaging hole 2033. Therefore, when the rotating shaft 301 is inserted into the first engaging hole 2033 on the side facing the rotating member 203, the third positioning surface 3012 can abut against the fourth positioning surface 20331 to position and limit the rotating shaft 301 and the rotating member 203, so that the rotating shaft 301 and the rotating member 203 remain relatively fixed, so that the rotating member 203 can follow the rotating shaft 301 to realize rotation relative to the fixed member 102.

[0054] Specifically, the cooperation between the first positioning surface 3022 and the second positioning surface 10231, and the cooperation between the fourth positioning surface 20331 and the third positioning surface 3012 can achieve precise alignment, ensuring that the damping member 302 and the second engaging hole 1023, as well as the rotating shaft 301 and the first engaging hole 2033 can be correctly positioned during installation, avoiding deviation or instability during the installation process, and improving the assembly accuracy of the protective cover 1000 with a keyboard.

[0055] Specifically, the first positioning surface 3022 and the second positioning surface 10231 are in contact with each other, which can ensure that the damping member 302 is relatively fixed to the second engaging hole 1023, and prevent the damping member 302 from accidentally loosening or falling off after being installed with the second engaging hole 1023. The fourth positioning surface 20331 is in contact with the third positioning surface 3012, which can ensure that the rotating shaft 301 remains stable in the first engaging hole 2033, and prevent the rotating shaft 301 from accidentally loosening, falling off or rotating after being installed with the first engaging hole 2033, thereby improving the overall stability and safety of the protective cover 1000 with a keyboard.

[0056] refer to Figure 3 , Figure 8 and Fig. 9 The first stop portion 3011 includes an abutment plate 30111 and a first arc-shaped protrusion 30112 that are connected to each other. The first arc-shaped protrusion 30112 is arranged on the side of the abutment plate 30111 facing the damping member 302. The second stop portion 3021 includes an abutment surface 30211 and a second arc-shaped protrusion 30212 arranged on the outer circle of the abutment surface 30211. One side of the abutment plate 30111 abuts against the rotating member 203, and the other side abuts against the second arc-shaped protrusion 30212. The first arc-shaped protrusion 30112 abuts against the abutment surface 30211, so that the first arc-shaped protrusion 30112 can abut against the second arc-shaped protrusion 30212 during the rotation of the rotating shaft 301 relative to the damping member 302.

[0057] One side of the abutment plate 30111 abuts against the rotating member 203, and the other side abuts against the second arc-shaped protrusion 30212 of the second stop portion 3021. The first arc-shaped protrusion 30112 abuts against the abutment surface 3021 of the second stop portion 3021, thereby achieving the damping member 302 abutting against the rotating member 203 through the abutment between the first stop portion 3011 and the second stop portion 3021, so as to provide a damping force for the rotating member 203 during its rotation relative to the fixed member 102. During the rotation of the rotating shaft 301 relative to the damping member 302, the first arc-shaped protrusion 30112 can counteract the second arc-shaped protrusion 30212, thereby limiting the rotation range of the rotating shaft 301 relative to the damping member 302, ensuring that the rotating shaft 301 rotates within a preset angle range, avoiding over-rotation of the rotating shaft 301 and causing damage to the protective cover 1000 with a keyboard, thereby improving the safety and stability of the protective cover 1000 with a keyboard.

[0058] Specifically, the first arc-shaped protrusion 30112 and the second arc-shaped protrusion 30212 counteract each other during the rotation process, which can effectively prevent the rotating shaft 301 from excessively rotating relative to the damping member 302, avoid damage to the rotating shaft 301 and the damping member 302 or cause unnecessary pressure, and avoid the risk of the tablet computer accidentally falling on the connecting plate assembly 200, thereby ensuring the safety of the protective cover 1000 with a keyboard and extending the service life of the protective cover 1000 with a keyboard.

[0059] Specifically, the two sides of the abutment plate 30111 respectively abut against the second arc-shaped protrusion 30212 and the rotating member 203. At the same time, the first arc-shaped protrusion 30112 abuts against the abutment surface 30211, which can enhance the damping force when the rotating shaft 301 drives the rotating member 203 to rotate, ensuring that the rotating shaft 301, the rotating member 203, the connecting plate assembly 200 and the tablet computer can stay at a specific position after rotating to avoid unnecessary shaking or loosening, thereby improving the overall stability of the protective cover 1000 with a keyboard, avoiding accidents caused by misoperation, and protecting the safety of the tablet computer and the protective cover 1000 with a keyboard.

[0060] refer to Fig.11 and Fig.13 The keyboard panel 101 includes a top shell 1011 and a bottom surface 1012 that are interconnected. The keyboard is arranged on the top shell 1011. A through slot 10111 corresponding to the fixing member 102 is provided on the top shell 1011. The fixing member 102 includes a connecting piece 1021 and a fixing platform 1022 that are interconnected. The second engaging hole 1023 is located on the fixing platform 1022. The connecting piece 1021 passes through the through slot 10111 and is fixedly connected to the top shell 1011.

[0061] The connecting piece 1021 of the fixing member 102 is used to pass through the through slot 10111 set on a side of the top shell 1011 and be fixedly connected to the top shell 1011. The through slot 10111 can limit and position the connecting piece 1021 and the fixing member 102, thereby ensuring that the connection position of the connecting piece 1021 and the top shell 1011 is accurate, avoiding movement or swinging of the fixing member 102 relative to the top shell 1011 during use, and improving the overall stability of the protective cover 1000 with a keyboard.

[0062] Specifically, the top shell 1011 is connected to the connecting piece 1021 through the through slot 10111 to avoid interference or collision between the fixing platform 1022 and the keyboard board 101. The connecting piece 1021 can smoothly pass through the through slot 10111 to ensure the normal installation between the fixing member 102 and the keyboard board 101, while protecting the keyboard board 101 and the fixing member 102 from damage.

[0063] Specifically, through the connection between the connecting piece 1021 and the top shell 1011 , the structural stability of the protective cover 1000 with a keyboard is enhanced, thereby improving the stability and reliability of the protective cover 1000 with a keyboard.

[0064] refer to Figure 5 , Figure 7 and Fig.12 The rotating member 203 includes a boss 2031 and a locking sleeve 2032 connected to each other, a first locking hole 2033 is provided on the locking sleeve 2032, an extension platform 2021 is provided on the side of the second connecting plate 202 away from the first connecting plate 201, and a locking groove 20211 corresponding to the boss 2031 is provided on the extension platform 2021, the boss 2031 is engaged with the locking groove 20211, and a limiting plate 20321 corresponding to the side of the extension platform 2021 facing the keyboard panel 101 is also provided on the locking sleeve 2032, and the limiting plate 20321 is abutted against the extension platform 2021.

[0065] The boss 2031 can be connected with the extension platform 2021 by snapping, which can make the installation between the rotating part 203 and the second connecting plate 202 more convenient, and can help to achieve quick positioning and assembly between the boss 2031 and the extension platform 2021, and is easier to align and fix during the installation process, thereby simplifying the installation steps and improving the operability of the protective cover 1000 with a keyboard.

[0066] Specifically, the boss 2031 and the slot 20211 are engaged and connected, and the extension platform 2021 and the rotating member 203 can be connected or disconnected conveniently and quickly, thereby facilitating the connection and removal between the connecting plate assembly 200 and the keyboard board 101. This allows the user to flexibly disassemble and assemble the protective cover 1000 with a keyboard, thereby improving the flexibility and applicability of the protective cover 1000 with a keyboard.

[0067] Further, refer to Figure 7 In this embodiment, a limit plate 20321 is provided on the locking sleeve 2032, and the limit plate 20321 corresponds to a side surface of the extension platform 2021 facing the keyboard board 101. Therefore, in the actual installation process, due to the correspondence between the limit plate 20321 and the side surface of the extension platform 2021, the user can easily identify the correct installation direction of the second connecting plate 202, so that the user can install the second connecting plate 202 on the boss 2031 in the correct direction, avoid the wrong installation direction of the second connecting plate 202, resulting in the protection cover 1000 with a keyboard being unable to be used normally and being damaged, and can also reduce the time required for re-identification and installation, and reduce the difficulty and time of installing the protection cover 1000 with a keyboard.

[0068] On the other hand, the abutment between the limiting plate 20321 and the extension platform 2021 can increase the connection area between the rotating member 203 and the extension platform 2021, so that the connection between the rotating member 203 and the second connection plate 202 is more firm and stable.

[0069] It should be noted that, in this embodiment, the extension platform 2021 can be against the bottom of the tablet computer, providing a stable support for the tablet computer, ensuring that the tablet computer is stably placed on the connecting plate assembly 200 during use, and increasing the stability and safety of the protective cover with keyboard 1000. The extension platform 2021 can help the connecting plate assembly 200 balance the weight of the tablet computer, distributing the weight and pressure to the keyboard board 101 and the desktop through the rotating member 203 and the fixing member 102, reducing the pressure concentration on the connecting plate assembly 200, reducing the risk of damage, and extending the service life of the protective cover with keyboard 1000.

[0070] On the other hand, because the extension platform 2021 has a certain thickness, when the plane where the connecting plate assembly 200 is located is parallel to the plane where the keyboard plate assembly 100 is located, the second connecting plate 202 and the keyboard plate assembly 100 can have a preset distance due to the existence of the second connecting plate 202. The preset distance is used to place the tablet computer, so it can avoid the second connecting plate 202 from rotating beyond the limit and affecting the tablet computer to a certain extent, thereby protecting the tablet computer to a certain extent.

[0071] It should be noted that the rotational relationship between the first connecting plate 201 and the second connecting plate 202 has the following usage scenarios. The first scenario is that when the first connecting plate 201 and the second connecting plate 202 are in the same plane and the connecting plate assembly 200 is connected to the keyboard plate assembly 100, the connecting plate assembly 200 can adjust the angle and position between it and the keyboard plate assembly 100 through the rotational connection between the rotating member 203 and the fixed member 102, making it convenient for users to operate by using the keyboard plate assembly 100.

[0072] The second situation is that when the connecting plate assembly 200 is connected to the keyboard plate assembly 100 through the fixing member 102 and the rotating member 203, the first connecting plate 201 is rotated at a certain angle relative to the second connecting plate 202, so that the user can freely adjust the angle and direction of the tablet computer connected to the first connecting plate 201 through the rotating connection between the keyboard plate assembly 100 and the connecting plate assembly 200, and the rotating connection between the first connecting plate 201 and the second connecting plate 202, thereby facilitating the user's use of the tablet computer.

[0073] The third situation is that the connecting plate assembly 200 is separated from the boss 2031 on the rotating member 203 through the slot 20211, so that the connecting plate assembly 200 is separated from the keyboard plate assembly 100. At this time, the second connecting plate 202 is rotated relative to the first connecting plate 201, so that a certain angle is formed between the second connecting plate 202 and the tablet computer, so that the second connecting plate 202 and the bottom of the tablet computer complete the supporting action together, and the connecting plate assembly 200 is supported (such as Fig.16 At this time, the connecting plate assembly 200 is in the supporting mode, so that the tablet computer is in an upright state, which is convenient for the user to use the tablet computer only through the connecting plate assembly 200.

[0074] In the fourth case, the connecting plate assembly 200 is separated from the boss 2031 on the rotating member 203 through the slot 20211, so that the connecting plate assembly 200 is separated from the keyboard plate assembly 100. At this time, the second connecting plate 202 is rotated relative to the first connecting plate 201, so that a certain angle is formed between the second connecting plate 202 and the first connecting plate 201, and the second connecting plate 202 and the first connecting plate 201 jointly complete the supporting action to support the tablet computer (such as Fig.17 At this time, the connecting plate assembly 200 is in handwriting mode, so that the tablet computer is placed in a nearly horizontal manner, so that the user can perform handwriting or drawing operations on the tablet computer only through the connecting plate assembly 200.

[0075] refer to Fig.12 A receiving cavity 20311 is disposed in the boss 2031 , a first magnetic component 20312 is disposed in the receiving cavity 20311 , and a second magnetic component corresponding to the first magnetic component 20312 is disposed in the slot 20211 .

[0076] The boss 2031 can be connected by snapping with the extension platform 2021. A first magnetic component 20312 is arranged in the accommodating cavity 20311 of the boss 2031, and a second magnetic component is arranged in the slot 20211, so that the first magnetic component 20312 is magnetically connected with the second magnetic component, which can further improve the connection strength between the boss 2031 and the extension platform 2021, thereby enhancing the connection stability between the rotating component 203 and the second connecting plate 202.

[0077] The magnetic connection between the first magnetic member 20312 and the second magnetic member can not only strengthen the connection strength between the boss 2031 and the extension platform 2021, but also make the installation between the rotating member 203 and the second connecting plate 202 more convenient. Because the magnetic attraction between the first magnetic member 20312 and the second magnetic member can help the boss 2031 and the extension platform 2021 to be quickly positioned and assembled, and it is easier to align and fix during the installation process, which simplifies the installation steps and improves the ease of operation of the protective cover 1000 with a keyboard.

[0078] Specifically, the magnetic connection can increase the stability of the connection between the boss 2031 and the extension platform 2021. The magnetic attraction can help maintain the position between the second connecting plate 202 and the rotating member 203, prevent accidental movement or swing, and ultimately enhance the stability of the protective cover 1000 with a keyboard during use.

[0079] It should be noted that a second magnetic member can be arranged in the slot 20211 to be magnetically connected to the first magnetic member 20312 in the boss 2031, and a magnetically attractable metal that can be magnetically connected to the first magnetic member 20312 can also be arranged in the slot 20211. In addition to the above-mentioned arrangement, the extension platform 2021 can also be made of a magnetically attractable metal material, so that the first magnetic member 20312 in the boss 2031 is directly magnetically connected to the extension platform 2021. The magnetically attractable metal materials include iron, nickel, cobalt, and steel.

[0080] refer to Figure 5 A plurality of limiting grooves 2012 are provided on one side of the first connecting plate 201 facing the keyboard plate 101 , and a third magnetic member is provided in the limiting grooves 2012 .

[0081] A plurality of limiting grooves 2012 are arranged on one side of the first connecting plate 201 facing the keyboard plate 101, that is, on one side of the first connecting plate 201 facing the tablet computer, and a third magnetic member is arranged in the limiting groove 2012, so that the third magnetic member is magnetically connected to the tablet computer. This can keep the tablet computer on the protective cover 1000 with a keyboard stable, avoid displacement and shaking between the tablet computer and the protective cover 1000 with a keyboard during use, and ensure the safety and stability of the tablet computer when connected to the protective cover 1000 with a keyboard.

[0082] Specifically, the third magnetic member enables the first connecting plate 201 and the tablet computer to be connected by magnetic attraction. The magnetic attraction connection can not only maintain the stability of the connection between the protective cover 1000 with a keyboard and the tablet computer, but also facilitate the installation and removal of the first connecting plate 201 and the tablet computer, thereby improving the easy installation and removal capability of the protective cover 1000 with a keyboard.

[0083] Specifically, the magnetic connection between the third magnetic member and the tablet computer can improve the safety of the connection. The magnetic connection is more secure, can effectively prevent accidental falling off or loosening, and improve the stability and reliability of the protective cover 1000 with a keyboard.

[0084] It should be noted that the position of the upper limit groove 2012 on the first connecting plate 201 is set to correspond to the metal or magnetically attractive area on the side of the tablet computer facing away from the screen. This can not only reduce the number of third magnetic parts and reduce production costs, but also avoid the third magnetic parts from affecting the non-magnetic area of ​​the tablet computer.

[0085] refer to Fig.14 and Fig.15 The protective cover 1000 with a keyboard also includes a decorative piece 500, which is arranged between the two fixing pieces 102 and located at the bottom of the rotating piece 203. The decorative piece 500 is provided with a plurality of positioning protrusions 501, and the fixing piece 102 is provided with positioning grooves 1024 corresponding to the positioning protrusions 501. The positioning grooves 1024 are detachably connected to the positioning protrusions 501. A supporting surface 502 is provided at the bottom of the decorative piece 500, and the plane where the supporting surface 502 is located is coplanar with the plane where the bottom surface 1012 is located.

[0086] The decorative member 500 is used to shield and protect the first rotating assembly 300, prevent the external environment from affecting the first rotating assembly 300, and maintain the normal rotation function of the rotating shaft 301. On the other hand, the bottom of the decorative member 500 is provided with a support surface 502, and the support surface 502 is coplanar with the plane where the bottom surface 1012 of the keyboard plate 101 is located, so that the support and stability of the keyboard plate assembly 100 can be enhanced, so that the contact area between the protective cover 1000 with the desktop, platform and other planes is larger, so that the protective cover 1000 with the keyboard is more stable during use. On the other hand, the provision of the decorative member 500 can make the appearance of the entire protective cover 1000 with the keyboard more integrated and increase the appearance.

[0087] Specifically, a positioning groove 1024 corresponding to the positioning protrusion 501 on the decorative piece 500 is provided on the fixing piece 102, and the positioning protrusion 501 can be detachably connected to the positioning groove 1024, so that the installation and removal of the decorative piece 500 relative to the fixing piece 102 is more convenient and quick, saving the time required for the installation process of the decorative piece 500.

[0088] Specifically, the bottom surface 1012 of the decorative piece 500 is provided with a supporting surface 502, and the plane where the supporting surface 502 is located is coplanar with the plane where the bottom surface 1012 is located, which helps to provide stable support and uniform force for the protective cover 1000 with keyboard, while making the protective cover 1000 with keyboard more stable as a whole.
