DETAILED DESCRIPTION

[0032] It should be noted that the embodiments and features in the embodiments in the present application can be combined with each other without conflict. The preferred embodiments of the present application will be described in detail with reference to the drawings.

[0033] The utility model embodiment provides a kind of tablet computer protective sleeve 1000 with keyboard, refer to Figures 1-3 As shown in the figure, the tablet computer protective sleeve 1000 with keyboard includes rotating module 100, mounting plate 200 and keyboard plate 300, rotating module 100 includes first connecting piece 110, rotating shaft assembly 130 and two second connecting pieces 120, first connecting piece 110 is located between two second connecting pieces 120, the side of first connecting piece 110 towards second connecting piece 120 is equipped with first connecting hole 111, the side of second connecting piece 120 towards first connecting piece 110 is equipped with second connecting hole 121, rotating shaft assembly 130 includes rotating shaft 131 and damping member 132, one end of rotating shaft 131 is connected with first connecting hole 111, the other end is rotationally connected with damping member 132, damping member 132 is located in second connecting hole 121, and is connected with second connecting hole 121, first limiting portion 1312 is provided on rotating shaft 131, second limiting portion 1321 corresponding with first limiting portion 1312 is provided on damping member 132, and first limiting portion 1312 can be abutted with second limiting portion 1321;First connecting piece 110 is connected with mounting plate 200, and mounting plate 200 is used for connecting tablet computer;Second connecting piece 120 is connected with keyboard plate 300;Wherein, the side of first limiting portion 1312 abuts with first connecting piece 110, the other side abuts with second limiting portion 1321, to provide damping force, first limiting portion 1312 can be abutted with second limiting portion 1321 in rotating process, to limit the rotating range of rotating shaft 131.

[0034] The mounting plate 200 and the keyboard plate 300 are connected by the rotating module 100 to facilitate the user to operate the tablet computer through the keyboard. The first connecting piece 110 in the rotating module 100 is connected with the mounting plate 200, and the second connecting piece 120 is connected with the keyboard plate 300. The first connecting piece 110 and the second connecting piece 120 are connected by the rotating shaft assembly 130 to realize the relative rotation of the mounting plate 200 and the keyboard plate 300. One end of the rotating shaft 131 is connected with the first connecting hole 111 arranged on the first connecting piece 110, and the other end is connected with the damping piece 132. The damping piece 132 is connected with the second connecting hole 121 arranged on the second connecting piece 120. Therefore, when the rotating shaft 131 rotates relative to the damping piece 132, the damping piece 132 will not rotate with the rotating shaft 131. Because the rotating shaft 131 is connected with the first connecting hole 111, the first connecting piece 110 at the other end can be rotated together to ensure the rotation relationship between the first connecting piece 110 and the second connecting piece 120. At the same time, the second limiting part 1321 of the damping piece 132 is abutted with the first limiting part 1312 of the rotating shaft 131 and the first connecting piece 110 to provide damping force when the rotating shaft 131 rotates the first connecting piece 110, so that the first connecting piece 110 can be fixed relative to the second connecting piece 120 when the rotating shaft 131 rotates relative to the damping piece 132 to the required position. Therefore, in actual use, the user can adjust the mounting plate 200 to control the angle and position of the tablet computer, and when adjusted to the required position, the tablet computer and the mounting plate 200 can be fixed relative to the keyboard plate 300, which is convenient for the user to adjust the tablet computer to the required position and angle to meet the different use scenarios and needs of the user and facilitate the operation of the user. At the same time, it can also ensure the stability and safety of the tablet computer on the tablet computer protective sleeve 1000 with the keyboard. The first limiting part 1312 is arranged on the rotating shaft 131 to limit the rotation range of the rotating shaft 131 by cooperating with the second limiting part 1321 on the damping piece 132. During the rotation of the rotating shaft 131 relative to the damping piece 132, the first limiting part 1312 can abut against the second limiting part 1321 to limit the rotation range of the rotating shaft 131, avoid the rotating shaft 131 from rotating out of limit, and affect the tablet computer on the mounting plate 200, avoid the tablet computer from shaking or falling during use, and ensure the stability and safety of the tablet computer during use.

[0035] Specifically, the first connecting piece 110 is connected with the mounting plate 200, the second connecting piece 120 is connected with the keyboard plate 300, and the first connecting piece 110 and the second connecting piece 120 are rotationally connected through the rotating shaft assembly 130, so that the mounting plate 200 can rotate relative to the keyboard plate 300. One end of the rotating shaft 131 is clamped and connected with the first connecting piece 110, and the other end is rotationally connected with the second connecting piece 120, so as to ensure the stability of the rotation connection between the keyboard plate 300 and the mounting plate 200.

[0036] Specifically, the damping piece 132 in the rotating shaft assembly 130 is abutted with the first connecting piece 110 through the second limiting part 1321 and the first limiting part 1312, so that the friction between the damping piece 132 and the first connecting piece 110 is increased, thereby providing a damping effect when the first connecting piece 110 rotates relative to the second connecting piece 120, so that the rotating shaft 131 is limited to stay at a certain position during rotation relative to the damping piece 132. Avoid sudden movement or shaking of the rotating shaft 131 relative to the damping piece 132, improve the stability of the rotating module 100 and the experience of using the keyboard-equipped tablet computer protective sleeve 1000.

[0037] Specifically, the abutment between the first limiting part 1312 and the second limiting part 1321 can limit the rotation range of the rotating shaft 131, ensure that the mounting plate 200 moves within a predetermined angle range, and avoid excessive rotation or rotation of the mounting plate 200.

[0038] Reference Figure 3 The rotating shaft 131 further includes a clamping segment 1311 and a rotating segment 1313 respectively arranged on opposite sides of the first limiting part 1312, and the clamping segment 1311, the first limiting part 1312 and the rotating segment 1313 are connected in sequence. The clamping segment 1311 is clamped and connected with the first connecting hole 111, and the rotating segment 1313 is rotationally connected with the damping piece 132.

[0039] The clamping segment 1311 is used for clamping and connecting with the first connecting hole 111, which can improve the stability of the rotating shaft 131 and ensure that the rotating shaft 131 does not shake, loosen or slip out of the first connecting hole 111 during use. The rotating segment 1313 is used for rotationally connecting with the damping piece 132, which can make the rotation process of the rotating shaft 131 more stable and make the user operation more convenient. The first limiting part 1312 is arranged between the clamping segment 1311 and the rotating segment 1313, which can improve the structural strength of the rotating shaft 131, thereby ensuring the stability of the rotating shaft 131 during rotation.

[0040] Specifically, the user can easily adjust the angle and position of the mounting plate 200 relative to the keyboard plate 300 by rotating the rotating segment 1313 relative to the damping piece 132, which improves the operation convenience of the keyboard-equipped tablet computer protective sleeve 1000 and enhances the user experience.

[0041] Reference Figure 3 The rotating shaft assembly 130 further comprises a nut 133 and a compression washer 134. The nut 133 is fixedly connected to one end of the rotating section 1313 penetrating the damping member 132. The compression washer 134 is arranged between the damping member 132 and the nut 133, and the opposite sides of the compression washer 134 abut against the damping member 132 and the nut 133 respectively. The rotating section 1313 is rotationally connected to the compression washer 134, and the damping member 132 abuts against the first connecting member 110.

[0042] The nut 133 is fixedly connected to one end of the rotating section 1313 penetrating the damping member 132, and the nut 133 has the effect of fastening and limiting the damping member 132. In the process of rotating the rotating section 1313 relative to the damping member 132, the nut 133 prevents the rotating section 1313 from loosening or shaking relative to the damping member 132, or even sliding out of the damping member 132, thereby improving the stability of the rotating shaft assembly 130. The compression washer 134 is arranged between the nut 133 and the damping member 132, and the opposite ends of the compression washer 134 abut against the damping member 132 and the nut 133 respectively. The compression washer 134 can apply pressure to the damping member 132 and the nut 133 respectively, so that the overall structural strength of the rotating shaft assembly 130 is higher, and the connection between the components of the rotating shaft assembly 130 is more stable. In actual use, after the rotating shaft assembly 130 is connected with the first connecting member 110 and the second connecting member 120, because the position of the nut 133 relative to the rotating section 1313 is fixed, the force of the compression washer 134 on the nut 133 will act on the compression washer 134 itself. At the same time, the abutting force of the compression washer 134 on the damping member 132 and the reaction force of the nut 133 on the compression washer 134 can force the damping member 132 to press against the first connecting member 110, so that the abutting effect of the damping member 132 on the first connecting member 110 is more compact, thereby increasing the friction between the damping member 132 and the first connecting member 110, and finally achieving the damping effect during the relative rotation of the first connecting member 110 and the second connecting member 120.

[0043] Specifically, the compression washer 134 can enhance the pressure of the damping member 132, further improve the damping effect of the damping member 132, make the rotating process more stable, avoid the sudden movement or shaking of the first connecting member 110, and improve the stability and user experience of the keyboard-equipped tablet computer protective sleeve 1000.

[0044] Specifically, the rotational connection design of the rotating section 1313 and the compression washer 134 can make the rotating process of the rotating shaft 131 more smooth, reduce unnecessary friction, improve the smoothness of the rotation of the rotating shaft 131, and make it more convenient for users to operate the keyboard-equipped tablet computer protective sleeve 1000.

[0045] Specifically, in actual use, the position of the adjusting nut 133 on the rotating section 1313 can be adjusted to adjust the pressure of the compression gasket 134, so as to adjust the pressure of the damping member 132, finally realize the precise control of the damping force during rotation, meet different use requirements of the user, and improve the flexibility and application range of the keyboard-equipped tablet computer protective sleeve 1000.

[0046] With reference to Figure 4 and Figure 5 , the first limiting part 1312 is located on the side of the damping member 132 away from the compression gasket 134, the first limiting part 1312 comprises an abutting disc 13121 and a first arc-shaped protrusion 13122 connected with each other, the first arc-shaped protrusion 13122 is arranged on the side of the abutting disc 13121 facing the rotating section 1313, the second limiting part 1321 comprises an abutting surface 13212 and a second arc-shaped protrusion 13211 arranged on the outer circle of the abutting surface 13212, one side of the abutting disc 13121 abuts against the first connecting piece 110, and the other side abuts against the second arc-shaped protrusion 13211 of the second limiting part 1321, and the first arc-shaped protrusion 13122 abuts against the abutting surface 13212 of the second limiting part 1321, so that the first arc-shaped protrusion 13122 can abut against the second arc-shaped protrusion 13211 during the rotation of the rotating section 1313 relative to the damping member 132.

[0047] The one side of the abutting disc 13121 abuts against the first connecting piece 110, and the other side abuts against the second arc-shaped protrusion 13211 of the second limiting part 1321, and the first arc-shaped protrusion 13122 abuts against the abutting surface 13212 of the second limiting part 1321, so that the damping member 132 abuts against the first connecting piece 110 through the abutment of the first limiting part 1312 and the second limiting part 1321, to provide damping force during the rotation of the first connecting piece 110 relative to the second connecting piece 120. During the rotation of the rotating shaft 131 relative to the damping member 132, the first arc-shaped protrusion 13122 can abut against the second arc-shaped protrusion 13211, so as to limit the rotation range of the rotating shaft 131 relative to the damping member 132, ensure the rotation of the rotating shaft 131 within a predetermined angle range, avoid excessive rotation of the rotating shaft 131, cause damage to the keyboard-equipped tablet computer protective sleeve 1000, and improve the safety and use stability of the keyboard-equipped tablet computer protective sleeve 1000.

[0048] Specifically, the abutment of the first arc-shaped protrusion 13122 and the second arc-shaped protrusion 13211 during the rotation can effectively prevent the excessive rotation of the rotating shaft 131 relative to the damping member 132, avoid damage to the rotating shaft 131 and the damping member 132 or cause unnecessary pressure, also avoid the risk of accidental falling of the tablet computer on the mounting plate 200, ensure the use safety of the keyboard-equipped tablet computer protective sleeve 1000, and prolong the service life of the keyboard-equipped tablet computer protective sleeve 1000.

[0049] Specifically, the two sides of the abutting disc 13121 abut against the second arc-shaped protrusion 13211 and the first connecting piece 110 respectively, and meanwhile, the first arc-shaped protrusion 13122 abuts against the abutting surface 13212, which can enhance the damping force when the rotating shaft 131 drives the first connecting piece 110 to rotate, ensure that the rotating shaft 131, the first connecting piece 110, the mounting plate 200 and the tablet computer can stay after being rotated to a specific position, avoid unnecessary shaking or loosening, improve the overall stability of the tablet computer protective sleeve 1000 with keyboard, avoid accidental situations caused by misoperation, protect the use safety of the tablet computer and the tablet computer protective sleeve 1000 with keyboard.

[0050] Reference Figure 9 The first limiting surface 1111 and the second limiting surface 13111 abut against each other.

[0051] The first limiting surface 1111 is arranged on the inner wall of the first connecting hole 111, and the second limiting surface 13111 is arranged on the side of the clamping segment 1311 facing the first connecting hole 111, so that when the clamping segment 1311 is inserted into the first connecting hole 111, the second limiting surface 13111 can abut against the first limiting surface 1111 to position and limit the clamping segment 1311, so that the clamping segment 1311 and the first connecting piece 110 remain relatively fixed, thereby enabling the first connecting piece 110 to rotate relative to the second connecting piece 120 following the clamping segment 1311.

[0052] Specifically, the cooperation between the first limiting surface 1111 and the second limiting surface 13111 can achieve precise alignment, ensure that the clamping segment 1311 can be correctly positioned with the first connecting hole 111 during installation, avoid deviation or instability during installation, and improve the assembly precision of the tablet computer protective sleeve 1000 with keyboard.

[0053] Specifically, the abutment between the first limiting surface 1111 and the second limiting surface 13111 can ensure that the clamping segment 1311 remains stable in the first connecting hole 111, prevent the clamping segment 1311 from accidentally loosening, falling off or rotating after being installed with the first connecting hole 111, improve the overall stability of the tablet computer protective sleeve 1000 with keyboard, and improve the safety of the tablet computer protective sleeve 1000 with keyboard.

[0054] Reference Figures 4 to 6The first connecting hole 111 is further provided with two sunken grooves 1112, and the two sunken grooves 1112 are respectively located at opposite ends of the first connecting hole 111. The first limiting part 1312 and the second limiting part 1321 are located in the sunken grooves 1112, and the side of the abutting disc 13121 away from the first arc-shaped protrusion 13122 abuts against the groove bottom of the sunken groove 1112.

[0055] The sunken grooves 1112 are used to accommodate the first limiting part 1312 and the second limiting part 1321, so that the first limiting part 1312 and the second limiting part 1321 are more stable in the first connecting part 110, the possibility of loosening or shaking between the first limiting part 1312 and the second limiting part 1321 is reduced, and the overall stability of the tablet computer protective sleeve 1000 with a keyboard is enhanced. The groove bottom of the sunken groove 1112 abuts against the side of the abutting disc 13121 away from the first arc-shaped protrusion 13122, so that the damping part 132 finally abuts against the first connecting part 110 through the first limiting part 1312 and the second limiting part 1321, and the damping force is provided by the damping part 132 during the rotation of the first connecting part 110 relative to the second connecting part 120.

[0056] Specifically, the presence of the sunken grooves 1112 can help ensure that the first limiting part 1312 and the second limiting part 1321 are correctly installed in the connecting hole, prevent misalignment or incorrect installation between the first limiting part 1312 and the second limiting part 1321, and improve the assembly precision and reliability of the tablet computer protective sleeve 1000 with a keyboard.

[0057] The provision of the sunken grooves 1112 can effectively protect the first limiting part 1312 and the second limiting part 1321, avoid the influence of the external environment on the abutting connection between the first limiting part 1312 and the second limiting part 1321, ensure the connection stability between the first abutting part and the second abutting part, ensure the abutment of the abutting disc 13121 with the second arc-shaped protrusion 13211 and the groove bottom of the sunken groove 1112, respectively, and the abutment of the first arc-shaped protrusion 13122 and the abutting surface 13212, and ensure that the damping effect during rotation is achieved. At the same time, it also ensures that the abutment between the first arc-shaped protrusion 13122 and the second arc-shaped protrusion 13211 during rotation is not affected, thereby ensuring the successful implementation of the rotation range limitation of the rotating shaft 131.

[0058] Specifically, accommodating the first limiting part 1312 and the second limiting part 1321 in the sunken grooves 1112 in the connecting hole can make the positional relationship between the first connecting part 110 and the second connecting part 120 more precise, and improve the compactness of the structure and the appearance of the tablet computer protective sleeve 1000 with a keyboard.

[0059] Reference Figure 1 and Figure 7The mounting plate 200 comprises a support plate 201 and a magnetic plate 202 connected with each other, and a rotating member 203 is arranged between the support plate 201 and the magnetic plate 202, and the support plate 201 and the magnetic plate 202 are rotatably connected through the rotating member 203.

[0060] The rotating member 203 is arranged between the magnetic plate 202 and the support plate 201, and the magnetic plate 202 and the support plate 201 are connected through the rotating member 203. Meanwhile, the magnetic plate 202 and the support plate 201 can be rotatably connected through the rotating member 203. When the support plate 201 remains at a current position, the magnetic plate 202 can rotate relative to the support plate 201, and when the magnetic plate 202 remains at a current position, the support plate 201 can rotate relative to the magnetic plate 202, which helps to improve the flexibility of the mounting plate 200. The support plate 201 and the magnetic plate 202 are connected through the rotating member 203, so that they can be relatively flexibly rotated, which provides a wider angle adjustment for the mounting plate 200, and facilitates the user to adjust the angle and position of the magnetic plate 202 and / or the support plate 201 according to the user's own needs, and improves the flexibility and applicability of the tablet computer protective sleeve 1000 with a keyboard in use.

[0061] Specifically, the magnetic plate 202 and the support plate 201 are rotatably connected through the rotating member 203, which can avoid wear caused by adjusting the relative position of the magnetic plate 202 and the support plate 201 through bending, improve the durability and reliability of the mounting plate 200, and prolong the service life of the mounting plate 200.

[0062] Specifically, the above-mentioned rotatable connection mode can provide stable connection between the magnetic plate 202 and the support plate 201, ensure smooth and reliable rotation between the support plate 201 and the magnetic plate 202, and increase the stability of the tablet computer protective sleeve 1000 with a keyboard. Meanwhile, it can also simplify the operation mode of the tablet computer protective sleeve 1000 with a keyboard, so that the user can easily adjust the angle or position of the mounting plate 200, and improve the ease of use of the tablet computer protective sleeve 1000 with a keyboard. On the other hand, the user can accurately adjust the relative position and angle of the support plate 201 and the magnetic plate 202 to meet the use requirements in different use scenarios, and expand the application range of the tablet computer protective sleeve 1000 with a keyboard.

[0063] Reference Figure 1 and Figure 7 The bottom of the support plate 201 is provided with a support table 2011 for abutting against the bottom of the tablet computer, and the magnetic plate 202 is provided with a plurality of first magnetic members.

[0064] The support table 2011 can abut against the bottom of the tablet computer to provide stable support for the tablet computer, so that the tablet computer is stably placed on the support plate 201 during use, and the stability and safety of the tablet computer protective sleeve 1000 with the keyboard are increased. The first magnetic member is arranged on the magnetic plate 202 and can be magnetically connected with the magnetic area at the bottom of the tablet computer, so that the tablet computer is firmly connected to the magnetic plate 202, the tablet computer is prevented from sliding or moving during use, and the stability and safety of the tablet computer protective sleeve 1000 with the keyboard are improved.

[0065] Specifically, the support table 2011 can help the mounting plate 200 balance the weight of the tablet computer, and disperse the weight and pressure to the keyboard plate 300 and the desktop through the first connecting piece 110 and the second connecting piece, so as to reduce the pressure concentration on the mounting plate 200, reduce the risk of damage, and prolong the service life of the tablet computer protective sleeve 1000 with the keyboard.

[0066] Specifically, by arranging the first magnetic member on the magnetic plate 202, the tablet computer can be conveniently and quickly installed and dismounted from the magnetic plate 202, the operation steps of dismounting are simplified, and the ease of use of the tablet computer protective sleeve 1000 with the keyboard is improved.

[0067] Reference Figure 1 and Figure 7 The side of the support table 2011 facing the first connecting piece 110 is provided with a clamping groove 20111, the first connecting piece 110 is provided with a clamping block 112 and a limiting plate 113, the clamping block 112 is clamped and connected with the clamping groove 20111, the clamping block 112 is provided with a second magnetic member, and the clamping groove 20111 is provided with a third magnetic member corresponding to the second magnetic member or a magnetically attractable metal, or the support table 2011 is made of a magnetically attractable metal. The limiting plate 113 corresponds to the side of the support table 2011 facing the keyboard plate, and the limiting plate 113 abuts against the support table 2011.

[0068] The clamping block 112 can be clamped and connected with the support table 2011, the second magnetic member is arranged in the clamping block 112, the third magnetic member is arranged in the clamping groove 20111, or a magnetically attractable metal material is arranged in the clamping groove 20111, so that the clamping block 112 can be magnetically connected with the support table 2011, the connection strength between the clamping block 112 and the support table 2011 can be further improved, and the connection stability between the first connecting piece 110 and the support plate 201 is enhanced.

[0069] Specifically, the connection mode of the magnetic attraction connection between the second magnetic member and the third magnetic member can not only strengthen the connection strength between the clamping block 112 and the support table 2011, but also make the installation of the first connecting piece 110 and the support plate 201 more convenient. Because the magnetic attraction force between the third magnetic member and the first magnetic member can help the clamping block 112 and the support table 2011 to realize quick positioning and assembly, and it is easier to align and fix during installation, which simplifies the installation steps and improves the operability of the tablet computer protective sleeve 1000 with keyboard.

[0070] Specifically, the clamping block 112 and the clamping groove 20111 are clamped and connected, and the support table 2011 and the first connecting piece 110 can be conveniently and quickly connected or disconnected, so as to facilitate the connection and disassembly between the mounting plate 200 and the keyboard plate 300. So that the user can flexibly disassemble and assemble the tablet computer protective sleeve 1000 with keyboard, improve the flexibility and applicability of the tablet computer protective sleeve 1000 with keyboard.

[0071] Further, referring to Figure 12 In this embodiment, a limiting plate 113 is further arranged on the first connecting piece 110, and the limiting plate 113 corresponds to the side of the support table 2011 facing the keyboard plate 300. Therefore, in the actual installation process, because of the corresponding relationship between the limiting plate 113 and the side of the support table 2011, the user can easily identify the correct installation direction of the second half body 402, so as to facilitate the user to install the second half body 402 on the clamping block 112 in the correct direction, avoid the installation direction of the second half body 402 being wrong, cause the tablet computer protective sleeve 1000 with keyboard to be unable to be normally used and damaged, and also reduce the required time for re-identification and installation, reduce the installation difficulty and time of the tablet computer protective sleeve 1000 with keyboard.

[0072] On the other hand, through the abutment between the limiting plate 113 and the support table 2011, the connection area between the first connecting piece 110 and the support table 2011 can be increased, so that the connection between the first connecting piece 110 and the support plate 201 is more firm and stable.

[0073] It should be noted that in addition to the above arrangement, the support table 2011 can also be made of a magnetically attractable metal material, such as iron, nickel, cobalt and steel. The second magnetic member in the clamping block 112 is directly magnetically attracted to the support table 2011.

[0074] It should be noted that the magnetic plate 202 is rotatably connected with the support plate 201, so in actual use, the first case is that when the magnetic plate 202 and the support plate 201 are in the same plane, and the mounting plate 200 is connected with the keyboard plate 300, the mounting plate 200 can adjust the angle and position between the mounting plate 200 and the keyboard plate 300 through the rotatable connection between the first connecting piece 110 and the second connecting piece 120, so as to facilitate the user to operate through the keyboard plate 300.

[0075] The second case is that when the mounting plate 200 is connected with the keyboard plate 300 through the second connecting piece 120 and the first connecting piece 110, the magnetic plate 202 is rotated relative to the support plate 201 by a certain angle, so that the user can freely adjust the angle and direction of the tablet computer connected to the magnetic plate 202 through the rotatable connection between the keyboard plate 300 and the mounting plate 200, and the rotatable connection between the magnetic plate 202 and the support plate 201, so as to facilitate the user to use the tablet computer.

[0076] The third case is that the mounting plate 200 is separated from the clamping block 112 on the first connecting piece 110 through the clamping groove 20111, so that the mounting plate 200 is separated from the keyboard plate 300. At this time, the support plate 201 is rotated relative to the magnetic plate 202, so that the support plate 201 and the bottom of the tablet computer form a certain angle to jointly complete the support action of the mounting plate 200 (as shown in Figure 10 At this time, it is the support mode of the mounting plate 200, so that the tablet computer remains in an upright state, and the user can use the tablet computer only through the mounting plate 200.

[0077] The fourth case is that the mounting plate 200 is separated from the clamping block 112 on the first connecting piece 110 through the clamping groove 20111, so that the mounting plate 200 is separated from the keyboard plate 300. At this time, the support plate 201 is rotated relative to the magnetic plate 202, so that the support plate 201 and the magnetic plate 202 form a certain angle, so that the mounting plate 200 can be placed horizontally on the desktop, and the support plate 201 and the magnetic plate 202 jointly complete the support action of the tablet computer (as shown in Figure 11 At this time, it is the handwriting mode of the mounting plate 200, so that the tablet computer is placed in a nearly horizontal manner, and the user can only perform handwriting or drawing operations on the tablet computer through the mounting plate 200.

[0078] Reference Figure 8 The bottom of the second connecting piece 120 is provided with a support end face 122, and the plane where the support end face 122 is located is coplanar with the plane where the bottom of the keyboard plate 300 is located.

[0079] The bottom of the second connecting piece 120 is provided with a supporting end face 122. When the tablet computer protective sleeve 1000 with keyboard needs to be placed on a plane such as a desktop or a platform for use, the supporting end face 122 can abut against the plane to support the entire tablet computer protective sleeve 1000 with keyboard together with the bottom of the keyboard plate 300. The supporting end face 122 can further increase the contact area of the tablet computer protective sleeve 1000 with keyboard and the plane, so that the tablet computer protective sleeve 1000 with keyboard is placed more stably and safely, and does not shake on the plane, thereby avoiding affecting the normal use of the tablet computer protective sleeve 1000 with keyboard and increasing the stability and safety of the tablet computer protective sleeve 1000 with keyboard.

[0080] Specifically, the coplanar arrangement of the supporting end face 122 and the bottom of the keyboard plate 300 helps to uniformly distribute the stress, reduces the local pressure of the tablet computer protective sleeve 1000 with keyboard at a certain position, improves the carrying capacity of the tablet computer protective sleeve 1000 with keyboard, and prolongs the service life of the tablet computer protective sleeve 1000 with keyboard.
