DETAILED DESCRIPTION

[0032] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. Now, in conjunction with the accompanying drawings, a detailed description of the preferred embodiments of the present utility model will be given.

[0033] The present invention provides an external keyboard 1000 for a tablet computer. Figure 1-3As shown, the external keyboard 1000 of the tablet computer includes: a keyboard panel 100, two positioning members 200, a rotating member 300 and a support plate assembly 400, wherein a keyboard is provided on one side of the keyboard panel 100; the positioning member 200 is provided on a side of the keyboard panel 100 adjacent to the side provided with the keyboard, and the two positioning members 200 are respectively arranged opposite to each other on the same side in the width direction of the keyboard panel 100; the rotating member 300 is provided between the two positioning members 200 and is rotatably connected to the two positioning members 200 respectively, and the rotating member 300 includes a first connecting boss 301; the support plate assembly 400 includes a first half body 401 and a second half body 402 that are rotatably connected, and a card slot 40221 is provided on a side of the second half body 402 facing away from the first half body 401, and the first connecting boss 301 is engaged and connected with the card slot 40221.

[0034] The keyboard panel 100 is provided with a keyboard, making it convenient for users to use the tablet computer via the keyboard. This facilitates tablet computer operation when using the tablet computer with the external keyboard 1000. Two positioning members 200 are provided on one side of the keyboard panel 100, along with a rotating member 300 rotatably connected to the two positioning members 200. The rotating member 300 includes a first connecting boss 301, which engages with a second half 402 of the support plate assembly 400. In other words, the keyboard panel 100 is rotatably connected to the support plate assembly 400 through the rotational connection between the positioning members 200 and the rotating member 300. In the support plate assembly 400, the first half 401 and the second half 402 are rotatably connected. Therefore, during actual use, the second half 402 can rotate relative to the keyboard panel 100 via the rotating member 300, and the first half 401 can also rotate relative to the second half 402. This expands the range of motion and flexibility of the tablet computer external keyboard 1000, thereby improving its applicability and operability. The rotational connection between the first half 401 and the second half 402 enables movement of the first half 401 relative to the second half 402. On the one hand, the physical structure of the rotational connection ensures smooth and fluid rotation between the first half 401 and the second half 402. Furthermore, the rotational connection allows the first half 401 to rotate relative to the second half 402 over a wider range than a bending connection. Furthermore, the rotational connection reduces wear and scratches between the first half 401 and the second half 402 compared to a bending connection, thereby extending the service life of the support plate assembly 400 to a certain extent, thereby increasing the service life of the entire tablet computer external keyboard 1000.

[0035] Specifically, the support plate assembly 400 is snap-connected with the rotating member 300 through the slot 40221 of the second half body 402, so that the support plate assembly 400 can be relatively easily disassembled and installed relative to the keyboard panel 100. The snap-connection method can achieve a firm connection between the keyboard panel 100 and the support plate assembly 400, and it is also convenient for users to perform disassembly operations.

[0036] Specifically, a slot 40221 is provided on the second half 402, and the first connecting boss 301 is engaged with the second half 402 via the slot 40221. In other words, the rotating member 300 is connected to the support plate assembly 400 via an engaging connection. This connection method is simple, portable, and easy to assemble and disassemble, thereby facilitating the inspection and maintenance of the tablet computer external keyboard 1000 and improving the convenience of the tablet computer external keyboard 1000.

[0037] Specifically, the keyboard panel 100 is provided with a positioning member 200, a rotating member 300 is rotatably connected to the positioning member 200, the rotating member 300 is engaged with the second half 402, and the second half 402 is rotatably connected to the first half 401. This arrangement ensures the structural stability of the tablet computer keyboard panel 100 and reduces the possibility of loosening or damage to the tablet computer external keyboard 1000, thereby extending the service life of the tablet computer external keyboard 1000.

[0038] It should be noted that the first half 401 and the second half 402 are rotationally connected, so in actual use, the first situation is that when the first half 401 and the second half 402 are in the same plane and the support plate assembly 400 is connected to the keyboard plate 100, the support plate assembly 400 can adjust the angle and position between it and the keyboard plate 100 through the rotational connection between the rotating member 300 and the positioning member 200, making it convenient for users to operate by using the keyboard plate 100.

[0039] The second situation is that when the support plate assembly 400 is connected to the keyboard plate 100 through the positioning member 200 and the rotating member 300, the first half body 401 is rotated at a certain angle relative to the second half body 402, so that the user can freely adjust the angle and direction of the tablet computer connected to the first half body 401 through the rotating connection between the keyboard plate 100 and the support plate assembly 400, and the rotating connection between the first half body 401 and the second half body 402, thereby facilitating the user's use of the tablet computer.

[0040] The third situation is to separate the support plate assembly 400 from the first connecting boss 301 on the rotating member 300 through the slot 40221, so that the support plate assembly 400 is separated from the keyboard panel 100. At this time, the second half 402 is rotated relative to the first half 401, so that a certain angle is formed between the second half 402 and the tablet computer, so that the second half 402 and the bottom of the tablet computer can jointly complete the supporting action to support the support plate assembly 400 (such as Figure 10 At this time, the support plate assembly 400 is in the support mode, so that the tablet computer remains in an upright state, making it convenient for the user to use the tablet computer only through the support plate assembly 400.

[0041] The fourth situation is to separate the support plate assembly 400 from the first connecting boss 301 on the rotating member 300 through the slot 40221, so that the support plate assembly 400 is separated from the keyboard plate 100. At this time, the second half 402 is rotated relative to the first half 401, so that a certain angle is formed between the second half 402 and the first half 401. The second half 402 and the first half 401 jointly complete the supporting action to support the tablet computer (such as Figure 11 At this time, the support plate assembly 400 is in handwriting mode, so that the tablet computer is placed in a nearly horizontal manner, which facilitates the user to perform handwriting or drawing operations on the tablet computer using only the support plate assembly 400.

[0042] refer to Figure 1 and Figure 2 The tablet computer external keyboard 1000 further includes a connecting shaft 403. A plurality of connecting members 404 are respectively provided on the side of the first half body 401 facing the second half body 402 and on the side of the second half body 402 away from the card slot 40221. The connecting shaft 403 passes through the plurality of connecting members 404 in sequence to rotatably connect the first half body 401 and the second half body 402.

[0043] Several connecting members 404 are provided on opposite sides of the first and second halves 401, 402. Connecting shafts 403 extend through the connecting members 404, connecting the first and second halves 401, 402. Furthermore, the first and second halves 401, 402 can be rotatably connected to each other via the connecting members 404 and the connecting shafts 403, respectively. This rotatable connection between the connecting shafts 403 and the connecting members 404 allows the first half 401 to rotate relative to the second half 402 while the second half 402 remains in its current position, and vice versa, thereby enhancing the flexibility of the support plate assembly. This arrangement allows users to easily adjust the angle and position of the first and / or second halves 401, 402, as needed, improving the flexibility and applicability of the tablet computer external keyboard 1000.

[0044] Specifically, by connecting the connecting member 404 to the connecting shaft 403, wear between the first half 401 and the second half 402 can be reduced, thereby extending the service life of the support plate assembly 400. This arrangement helps reduce friction and wear between the first half 401 and the second half 402 during relative rotation, thereby improving the durability of the tablet computer external keyboard 1000.

[0045] Specifically, through the above-mentioned rotational connection setting, the rotational connection of the first half 401 relative to the second half 402 becomes more stable, which helps to ensure that the tablet computer external keyboard 1000 remains stable during use, avoids shaking or instability, and improves the user experience.

[0046] On the other hand, the user can easily adjust the angle and position of the first half 401 relative to the second half 402 by rotating the connecting member 404 and the connecting shaft 403 to adapt to different usage scenarios and needs, thereby improving the flexibility and convenience of the tablet computer external keyboard 1000.

[0047] refer to Figure 2 and Figure 3 The connecting member 404 includes several connecting plates 4042 and a rotating sleeve 4041 connected to each other. The rotating sleeve 4041 is located on one side of the connecting plate 4042. The connecting shaft 403 is rotatably connected to the rotating sleeve 4041. A first connecting groove 4011 is provided on the first half body 401, and a second connecting groove 4021 is provided on the far end of the second half body 402. The first connecting groove 4011 and the second connecting groove 4021 are respectively connected to the connecting plates 4042.

[0048] A rotating sleeve 4041 is located on one side of the connecting plate 4042. The connecting shaft 403 is rotatably connected to the rotating sleeve 4041. The first and second halves 401, 402 are rotatably connected to the connecting shaft 403 via the rotating sleeve 4041 on the connecting member 404. The connecting member 402 is fixedly connected to the first and second connecting grooves 4011, 4021, respectively, via the connecting plate 4042, ensuring a secure connection of the connecting member 404 to the first and second halves 401, 402. Furthermore, the rotatable connection between the first and second halves 401, 402 and the connecting shaft 403 via the connecting member 404 prevents direct contact between the first and second halves 401, 402 and the connecting shaft 403, thus preventing wear and scratches caused by prolonged rotational connection between the first and second halves 401, 402 and the connecting shaft 403. This improves the durability and service life of the support plate assembly 400.

[0049] Specifically, connector 404 is connected to first half 401 via connecting plate 4042, and to second half 402 via connecting portion 4042. This increases the connection area between connector 404 and first half 401 or second half 402, reduces the likelihood of connector 404 loosening or falling off, ensures the stability and reliability of support plate assembly 400, and helps improve the reliability of tablet computer external keyboard 1000. The design of connector 404 makes keyboard installation and removal more convenient.

[0050] refer to Figure 3 The connecting plate 4042 includes a connecting portion 40421 and an extending portion 40422 that are connected to each other. The rotating sleeve 4041 is arranged on a side of the extending portion 40422 away from the connecting portion 40421 . The connecting portion 40421 is arranged in the first connecting groove 4011 or the second connecting groove 4021 .

[0051] The connecting portion 40421 of the connecting plate 4042 is configured to be fixedly connected to the first connecting groove 4011 or the second connecting groove 4021. The extending portion 40422 is configured to maintain a certain distance between the rotating sleeve 4041 disposed on one side of the extending portion 40422 and the connecting portion 40421. Specifically, the rotating sleeve 4041 maintains a certain distance from the second half 402 or the first half 401. This prevents overlap and interference between the first half 401 and the second half 402 during relative rotation of the first half 401 and the second half 402, thereby preventing the rotational range of the first half 401 and the second half 402 from being affected. This arrangement allows the first half 401 and the second half 402 to avoid each other during relative rotation, thereby preventing any impact on their rotational range and preventing scratches and wear between the first half 401 and the second half 402. This improves the service life and stability of the tablet computer external keyboard 1000.

[0052] Specifically, by providing an extension 40422 on the connecting plate 4042, the first half 401 and the second half 402 are allowed to avoid each other during relative rotation, thereby increasing the flexibility of the first half 401 and the second half 402 during relative rotation. A more flexible first half 401 and second half 402 can improve the applicability of the entire support plate assembly 400.

[0053] The design of the connecting portion 40421 and the extension portion 40422 facilitates installation and removal of the keyboard. The simple and effective combination of the connecting portion 40421 and the connecting slot allows for easy installation and removal, improving the operability of the tablet external keyboard 1000.

[0054] refer to Figure 1 、 Figure 4 and Figure 5 The support plate assembly 400 also includes a second connecting boss 4022, a card slot 40221 is provided on one side of the second connecting boss 4022, and the second connecting boss 4022 is provided on the side of the second half body 402 facing the keyboard panel 100, so that when the plane where the support plate assembly 400 is located is parallel to the plane where the keyboard panel 100 is located, there is a preset distance between the two.

[0055] The engaging slot 40221 is provided on the second connecting protrusion 4022, so that the first connecting protrusion 301 can be engaged and connected with the second connecting protrusion 4022 via the engaging slot 40221. In other words, the rotating member 300 can be connected to the support plate assembly 400 through the connection between the first connecting protrusion 301 and the second connecting protrusion 4022. The second connecting protrusion 4022 is provided on the side of the second half 402 facing the keyboard panel 100. Because the second connecting protrusion 4022 has a certain thickness, when the plane of the support plate assembly 400 is parallel to the plane of the keyboard panel 100, the second half 402 can maintain a predetermined distance from the keyboard panel 100. The predetermined distance is used to accommodate a tablet computer, thereby preventing the second half 402 from rotating beyond the limit and affecting the tablet computer, thereby protecting the tablet computer to a certain extent.

[0056] Specifically, the first connecting boss 301 and the second connecting boss 4022 engage in a snap-fit ​​connection. This snap-fit ​​connection typically provides a secure connection, ensuring stability and safety, and preventing accidental detachment or loosening. Furthermore, snap-fit ​​connections are typically simple to operate, allowing the user to easily snap the two components together without the need for complex tools or procedures. The snap-fit ​​connection is simple in design and typically installs quickly, saving time and effort.

[0057] It should be noted that, in this embodiment, the second half body 402 and the second connecting boss 4022 are integrally formed. In addition to the above arrangement, the second half body 402 can also be detachably connected or fixedly connected to the second connecting boss 4022.

[0058] refer to Figure 6 A receiving cavity 3011 is provided in the first connecting boss 301 , a first magnetic member 3012 is provided in the receiving cavity 3011 , and a second magnetic member corresponding to the first magnetic member 3012 is provided in the slot 40221 .

[0059] The first connecting boss 301 can be connected by snapping with the second connecting boss 4022. A first magnetic part 3012 is arranged in the accommodating cavity 3011 of the first connecting boss 301, and a second magnetic part is arranged in the slot 40221, so that the first magnetic part 3012 is magnetically connected to the second magnetic part or the second connecting boss 4022, which can further improve the connection strength between the first connecting boss 301 and the second connecting boss 4022, thereby enhancing the connection stability between the rotating part 300 and the second half body 402.

[0060] The magnetic connection between the first magnetic member 3012 and the second magnetic member not only strengthens the connection between the first connecting boss 301 and the second connecting boss 4022, but also facilitates the installation of the rotating member 300 and the second half 402. The magnetic attraction between the second and third magnetic members facilitates quick positioning and assembly of the first connecting boss 301 and the second connecting boss 4022, making alignment and securing easier during installation. This simplifies the installation process and improves the operability of the tablet computer external keyboard 1000.

[0061] Specifically, the magnetic connection method can increase the stability of the connection between the first connecting boss 301 and the second connecting boss 4022. The magnetic attraction can help maintain the position between the second half 402 and the rotating member 300, preventing accidental movement or swinging, and ultimately enhancing the stability of the tablet computer external keyboard 1000 during use.

[0062] It should be noted that a second magnetic member can be provided in the card slot 40221 to be magnetically connected to the first magnetic member 3012 in the first connecting boss 301, and a magnetically attractable metal that can be magnetically connected to the first magnetic member can also be provided in the card slot 40221. In addition to the above-mentioned setting method, the second connecting boss 4022 can also be made of a magnetically attractable metal material, so that the first magnetic member 3012 in the first connecting boss 301 is directly magnetically connected to the second connecting boss 4022. In the embodiment where the second connecting boss 4022 is made of a magnetically attractable metal material, the structural strength of the second connecting boss 4022 is higher, which can improve the durability and stability of the tablet computer external keyboard 1000. The second connecting boss 4022 made of a magnetically attractable metal material will have better strength and wear resistance, can provide a longer service life, and to a certain extent increase the stability of the tablet computer external keyboard 1000.

[0063] refer to Figure 6 、 Figure 8 and Figure 12 The rotating member 300 also includes a limiting sleeve 302 interconnected with the first connecting boss 301. The first connecting boss 301 is located on one side of the limiting sleeve 302. The opposite ends of the limiting sleeve 302 are respectively provided with a rotating shaft 500 engaged with the limiting sleeve 302. The end of the rotating shaft 500 away from the limiting sleeve 302 is connected to the positioning member 200 for damping rotation. The limiting sleeve 302 is provided with a limiting plate 3022 corresponding to the side of the second connecting boss 4022 facing the keyboard panel 100, and the limiting plate 3022 is abutted against the second connecting boss 4022.

[0064] The rotating member 300 includes a limiting sleeve 302 and a first connecting boss 301. The first connecting boss 301 is located on one side of the limiting sleeve 302. The first connecting boss 301 is used to connect to the support plate assembly 400, and the limiting sleeve 302 is used to rotatably connect to the two positioning members 200. A rotating shaft 500 is provided on opposite sides of the limiting sleeve 302. The side of the rotating shaft 500 facing the limiting sleeve 302 engages with the limiting sleeve 302. The end of the rotating shaft 500 facing the positioning member 200 is rotatably connected to the positioning member 200. Therefore, the positioning member 200 and the rotating member 300 can achieve a rotational connection between them through the rotating shaft 500.

[0065] Specifically, one end of the rotating shaft 500 is engaged with the limiting sleeve 302, and the other end is rotatably connected to the positioning member 200. Therefore, during actual use, when the support plate assembly 400 connected to the rotating member 300 rotates relative to the keyboard panel 100 connected to the positioning member 200, the rotating shaft 500 can follow the rotating member 300 and rotate relative to the positioning member 200. This arrangement provides good rotational flexibility between the positioning member 200 and the rotating member 300, allowing the rotating member 300 to rotate freely relative to the positioning member 200 within a certain range, meeting the different angle requirements of the user during use.

[0066] Specifically, the damping rotation connection between the rotating shaft 500 and the positioning member 200 can provide a certain damping effect, so that the rotating member 300 is subjected to a certain damping force during the rotation process, helping to control the rotation speed and stability of the rotating member 300 relative to the positioning member 200, so that the support plate assembly 400 can remain relatively stable after rotating within a certain range relative to the keyboard plate 100, so as to facilitate the user's use of the tablet computer connected to the tablet computer external keyboard 1000 and improve the operability of the tablet computer external keyboard 1000.

[0067] Further, refer to Figure 12 In this embodiment, a limiting plate 3022 is provided on the limiting sleeve 302. The limiting plate 3022 corresponds to the side of the second connecting protrusion 4022 facing the keyboard panel 100. Therefore, during the actual installation process, the corresponding relationship between the limiting plate 3022 and the side of the second connecting protrusion 4022 allows the user to easily identify the correct installation direction of the second half 402, thereby facilitating the user to install the second half 402 on the first connecting protrusion 301 in the correct direction. This avoids the possibility of the second half 402 being installed in the wrong direction, which could cause the tablet computer external keyboard 1000 to be malfunctioning or even damaged. This also reduces the time required for re-identification and installation, thereby reducing the difficulty and time required to install the tablet computer external keyboard 1000.

[0068] On the other hand, the contact between the limiting plate 3022 and the second connecting boss 4022 can increase the connection area between the rotating member 300 and the second connecting boss 4022 , making the connection between the rotating member 300 and the second half body 402 more firm and stable.

[0069] refer to Figure 7 and Figure 8A accommodating groove 201 is provided on the side of the positioning member 200 facing the rotating member 300, and a shaft sleeve 600 and a nut 700 are provided in the accommodating groove 201. The rotating shaft 500 is rotatably connected to the shaft sleeve 600, and the nut 700 is fixedly connected to the end of the rotating shaft 500 extending out of the shaft sleeve 600. A limiting plane 3021 is provided on the inner wall of the limiting sleeve 302, and a cutting plane 501 corresponding to the limiting plane 3021 is provided on the end of the rotating shaft 500 facing the limiting sleeve 302, and the limiting plane 3021 abuts against the cutting plane 501.

[0070] It should be noted that the two positioning members 200 are respectively arranged on the same side along the width direction of the keyboard panel 100, that is, the two positioning members 200 are arranged on the same side of the width direction of the keyboard panel 100, and the two positioning members 200 are arranged opposite to each other, that is, the accommodating grooves 201 of the two positioning members 200 are opposite to each other.

[0071] A sleeve 600 and a nut 700 are provided in the receiving groove 201 of the positioning member 200. One end of the rotating shaft 500 passes through the sleeve 600 and is fixedly connected to the nut 700. The rotating shaft 500 is rotatably connected to the sleeve 600. Therefore, when the rotating shaft 500 rotates relative to the sleeve 600, it can drive the nut 700 to rotate relative to the receiving groove 201. The sleeve 600 is used to be rotatably connected to the rotating shaft 500, facilitating the rotational connection between the rotating shaft 500 and the receiving groove 201, and can reduce the friction between the rotating shaft 500 and the receiving groove 201 to a certain extent, making the rotation process smoother. The nut 700 is used to fix and limit one end of the rotating shaft 500 to prevent the rotating shaft 500 from sliding out of the receiving groove 201 or shaking during rotation, thereby affecting the stability of the rotation. A limiting plane 3021 is provided on the inner wall of the limiting sleeve 302, and a cutting plane 501 corresponding to the limiting plane 3021 is provided on the side of the rotating shaft 500 facing the limiting sleeve 302. Therefore, when the rotating shaft 500 is inserted into the limiting sleeve 302, the cutting plane 501 can abut against the limiting plane 3021 to position and limit the rotating shaft 500, so that the rotating shaft 500 and the rotating part 300 remain relatively fixed, so that the rotating shaft 500 can rotate relative to the positioning part 200.

[0072] Specifically, a nut 700 is provided on one side of the sleeve 600, and the rotating shaft 500 is fixedly connected to the nut 700, thereby providing a certain limit to the rotating shaft 500, preventing the rotating shaft 500 from sliding or shifting during rotation. Furthermore, during actual use, the nut 700 can exert a certain amount of pressure on the sleeve 600. Since one end of the rotating shaft 500 is connected to the nut 700 and the other end is connected to the rotating member 300, the relative position of the positioning member 200 and the receiving groove 201 thereon can be kept stable during rotation, eliminating any gap between the positioning member 200 and the rotating member 300, thereby enhancing the reliability of the tablet computer external keyboard 1000.

[0073] It should be noted that the rotating shaft 500 and the sleeve 600 are respectively provided with a stop structure, so when the rotating shaft 500 rotates relative to the sleeve 600, the stop structure of the rotating shaft 500 and the stop structure on the sleeve 600 offset each other, which can play the effect of displaying the rotation range, thereby ensuring the safety of using the external keyboard 1000 for the tablet computer.

[0074] refer to Figure 9 The keyboard panel 100 includes a top shell 101 and a bottom surface 102 connected to each other. The keyboard is arranged on the top shell 101. The side of the top shell 101 is provided with a positioning groove 1011 corresponding to the positioning member 200. The positioning member 200 includes a connecting piece 202 and a positioning block 203 connected to each other. The accommodating groove 201 is located on the positioning block 203. The connecting piece 202 passes through the positioning groove 1011 and is fixedly connected to the top shell 101.

[0075] The connecting piece 202 of the positioning member 200 is used to pass through the positioning groove 1011 set on a side of the top shell 101 and be fixedly connected to the top shell 101. The positioning groove 1011 can limit and position the connecting piece 202 and the positioning member 200, ensuring that the position where the connecting piece 202 is connected to the top shell 101 is accurate, avoiding the positioning member 200 from moving or swinging relative to the top shell 101 during use, and improving the overall stability of the tablet computer external keyboard 1000.

[0076] Specifically, the top case 101 is connected to the connecting piece 202 via the positioning slot 1011 to prevent interference or collision between the positioning block 203 and the keyboard panel 100. The connecting piece 202 can smoothly pass through the positioning slot 1011, ensuring the normal installation between the positioning member 200 and the keyboard panel 100, while protecting the keyboard panel 100 and the positioning member 200 from damage.

[0077] Specifically, through the connection between the connecting piece 202 and the top shell 101 , the structural stability of the tablet computer external keyboard 1000 is enhanced, thereby improving the stability and reliability of the tablet computer external keyboard 1000 .

[0078] Referring to FIG. 1 , a plurality of limiting grooves 4012 are provided on one side of the first half body 401 facing the keyboard panel 100 , and a third magnetic member is provided in the limiting grooves 4012 .

[0079] A plurality of retaining grooves 4012 are provided on the side of the first half 401 facing the keyboard panel 100, that is, the side of the first half 401 facing the tablet computer. A third magnetic member is positioned within the retaining grooves 4012 to magnetically connect the third magnetic member to the tablet computer. This stabilizes the tablet computer when attached to the tablet computer external keyboard 1000, preventing movement and shaking between the tablet computer and the tablet computer external keyboard 1000 during use, and ensuring the safety and stability of the tablet computer when connected to the tablet computer external keyboard 1000.

[0080] Specifically, the third magnetic member allows the first half 401 to be connected to the tablet computer via magnetic attraction. This magnetic connection not only maintains the stability of the connection between the tablet computer external keyboard 1000 and the tablet computer, but also facilitates installation and removal of the first half 401 from the tablet computer, improving the ease of assembly and disassembly of the tablet computer external keyboard 1000.

[0081] Specifically, the magnetic connection between the third magnetic member and the tablet computer can improve the security of the connection. The magnetic connection is more secure and can effectively prevent accidental detachment or loosening, thereby improving the stability and reliability of the tablet computer external keyboard 1000.

[0082] It should be noted that the position of the upper limit groove 4012 on the first half body 401 is set to correspond to the metal or magnetic 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.
