[0002] With the development of electronic products, electronic products have also entered an era of portability, gradually transitioning from laptops to tablets. However, the use of tablets is relatively limited, requiring additional external devices (such as external keyboards) to expand their functions and enable tablets to have the productivity of laptops. Therefore, tablet keyboard protective cases have emerged.

[0003] When using a tablet with a tablet keyboard case, to ensure the tablet screen has a certain tilt angle, the part connecting the keyboard case to the tablet usually needs to be rotated to provide the required tilt angle. Some current tablet keyboard cases have an adjustable connection point that supports the tablet; however, this raises the tablet too high, affecting the screen's viewing experience and comfort. Another type of tablet keyboard case requires the tablet to be rested against the keyboard, with the keyboard case's rotating connection serving as one of the supports to maintain the screen's tilt. However, this type provides less effective support surface on the back of the tablet, making it less stable. Utility Model Content

Detailed Implementation

[0029] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0030] like Figures 1 to 5As shown, this utility model embodiment provides a tablet keyboard protective cover 100, including: a first cover 110 and a second cover 120 rotatably connected. The inner side of the first cover 110 is connected to a keyboard 130. The second cover 120 includes a first support plate 122 and a second support plate 124 rotatably connected. The first support plate 122 is rotatably connected to the first cover 110 through a first flexible connection part 140. A protective shell 150 is connected to the second support plate 124, and the protective shell 150 is used to place a tablet computer. A support member 160 is rotatably connected to the side of the keyboard 130 near the first flexible connection part 140. The support member 160 is connected to the first support plate 122 through a second flexible connection part 170, so that when the tablet keyboard protective cover 100 is closed, the width direction of the support member 160 rotates to be perpendicular to the plane where the keyboard 130 is located. When the tablet keyboard protective cover 100 is opened to support the tablet computer, the width direction of the support member 160 rotates to be parallel to the plane where the keyboard 130 is located.

[0031] Specifically, the rotating connection design of the first protective sleeve 110 and the second protective sleeve 120 allows for flexible switching between the use and storage states of the protective sleeve. The keyboard 130 on the first protective sleeve 110 provides users with a convenient input tool. The first flexible connecting part 140 and the second flexible connecting part 170 ensure the flexibility and stability of rotation between the components. For example, the first flexible connecting part 140 can be made of leather, which can realize the rotation function and provide a certain degree of cushioning and protection; the second flexible connecting part 170 can be made of a similar flexible material, ensuring that the support member 160 can be linked through the second flexible connecting part 170 when the first protective sleeve 110 rotates relative to the second protective sleeve 120.

[0032] The tablet keyboard protective case 100 provided in this embodiment of the application, through the rotatable connection of a first sleeve 110 and a second sleeve 120, can be closed or opened, facilitating the protection of the tablet computer during carrying and providing support for the tablet computer during use. The second sleeve 120 is rotatably connected to a first support plate 122 and a second support plate 124. When the tablet keyboard protective case 100 is opened for use, the first support plate 122, the second support plate 124, and the first sleeve 110 work together to form a stable support for the protective shell 150, thereby ensuring the stability of the tablet computer placed inside the protective shell 150. Furthermore, a support member 160 is rotatably connected to the side of the keyboard 130 near the first flexible connection portion 140. The support member 160 is connected to the first support plate 122 through a second flexible connection portion 170, and the rotation state of the support member 160 changes according to the open / closed state of the tablet keyboard protective case 100. When the tablet keyboard cover 100 is closed, the support member 160 rotates in the width direction to be perpendicular to the plane where the keyboard 130 is located. At this time, the support member 160 is retracted, making it easy to store and carry the entire cover. When the tablet keyboard cover 100 is opened to support the tablet, the support member 160 rotates in the width direction to be parallel to the plane where the keyboard 130 is located. The support member 160 unfolds, thereby expanding the support area (effective support surface) of the plane where the first protective cover 110 on the back of the tablet is located. This also allows for reasonable control of the tablet's tilt angle, preventing the screen from being excessively raised, and ensuring a good viewing experience and comfort for the user. By adopting the above method, the effective support surface can be extended during use, which helps to improve the stability of the tablet and makes it less likely to shake or tip over during use.

[0033] like Figure 2 and Figure 3 As shown, the keyboard 130 is provided with a positioning groove 132 extending along the length of the support member 160, and one side of the protective shell 150 can be held in the positioning groove 132.

[0034] Specifically, the shape and size of the positioning groove 132 match the side of the protective case 150 to ensure a tight and stable hold. This holding method can be completed manually, which is simple and convenient. In actual use, after the user places the tablet in the protective case 150, they only need to align the side of the protective case 150 with the positioning groove 132 to make the protective case 150 snap into the positioning groove 132, thus positioning and fixing the tablet. By holding the protective case 150 in the positioning groove 132, the tablet is not lifted into the air, which better restricts the horizontal movement of the tablet and improves the stability of the tablet. At the same time, precise positioning also helps to maintain the relative positional relationship between the tablet and the keyboard 130, making it convenient for users to input operations and improving the user experience. In addition, this design simplifies the user's operation process of installing and removing the tablet, improving the convenience of use.

[0035] like Figure 4 and Figure 6 As shown, a strap 180 is connected to the side of the second support plate 124 away from the first support plate 122. A first magnetic member 182 is provided on the strap 180. A second magnetic member 112 is provided inside the first protective sleeve 110. A third magnetic member 1242 is provided on the second support plate 124. When the tablet keyboard protective sleeve 100 is closed, the first magnetic member 182 can be magnetically connected to the second magnetic member 112. When the tablet keyboard protective sleeve 100 is open, the first magnetic member 182 can be magnetically connected to the third magnetic member 1242.

[0036] Specifically, when the tablet keyboard cover 100 is closed, the first magnetic component 182 can be magnetically connected to the second magnetic component 112, thereby firmly closing the cover and preventing it from being accidentally opened during carrying, thus providing good protection for the tablet computer. When the tablet keyboard cover 100 is open, the first magnetic component 182 can be magnetically connected to the third magnetic component 1242, so that the strap 180 is fixed on the side away from the protective case 150, avoiding affecting the viewing of the tablet computer screen inside the protective case 150.

[0037] In an optional embodiment of this application, a first magnetic element is provided in the positioning groove 132, and a second magnetic element is provided on the side of the protective shell 150 corresponding to the positioning groove 132. When the protective shell 150 is held in the positioning groove 132, the first magnetic element and the second magnetic element can be magnetically connected.

[0038] Specifically, the magnetic connection between the first and second magnetic components further enhances the stability of the tablet within the protective case. During use, the tablet may be subjected to external forces from various directions, such as accidental bumps or shaking during mobile device operation. The magnetic connection effectively resists these external forces, ensuring the tablet remains in the correct position and reducing the impact of tablet displacement on usability. Furthermore, the magnetic connection is simple and convenient to operate, without increasing the difficulty of use for the user; on the contrary, it enhances the user experience of installing and removing the tablet.

[0039] In an optional embodiment of this application, the protective shell 150 and the second support plate 124 are bonded or magnetically connected.

[0040] Specifically, adhesive bonding and magnetic bonding offer diverse options for connecting the protective case 150 to the second support plate 124. Adhesive bonding is suitable for cost-sensitive users who do not require frequent replacement of the protective case 150. Its simple structure and low cost meet basic usage needs and provide a stable fixation. Magnetic bonding, on the other hand, is more flexible. Users can easily replace the protective case 150 with different styles or functions according to their preferences, such as replacing it with a case 150 with heat dissipation or drop protection features, thus improving the product's scalability and personalization. At the same time, magnetic bonding, while ensuring connection stability, facilitates user operation and enhances the user experience.

[0041] like Figure 7 , Figure 8 and Figure 10 As shown, the keyboard 130 is provided with a boss 134, and the support member 160 is provided with a groove 162 corresponding to the boss 134. The boss 134 can be accommodated in the groove 162. The support member 160 is provided with a rotating shaft at opposite ends, and the rotating shaft is rotatably connected to the boss 134.

[0042] Specifically, the engagement of the boss 134 and the groove 162 serves a positioning and guiding function, ensuring that the support 160 remains stable during rotation and does not shift or wobble. The rotatable connection between the pivot and the boss 134 provides a flexible mechanism for the rotation of the support 160. For example, the pivot can be made of metal, possessing high strength and wear resistance, ensuring that the support 160 will not be damaged during frequent rotation. In actual use, the support 160 can rotate freely within a certain angle range around the pivot. When the tablet keyboard cover 100 is closed, the support 160 rotates until its width direction is perpendicular to the plane of the keyboard 130; when the cover is open for support, the support 160 rotates until its width direction is parallel to the plane of the keyboard 130.

[0043] like Figure 9 and Figure 10 As shown, the support member 160 includes a first housing 164 and a second housing 166 that are interlocked. The first housing 164 is provided with a plurality of snap-fit ​​protrusions, and the second housing 166 is provided with a plurality of snap-fit ​​grooves 1662. The portion of the second flexible connecting part 170 that extends into the support member 160 is provided with a plurality of through holes 172. The plurality of snap-fit ​​protrusions are correspondingly inserted into the plurality of through holes 172, and the plurality of snap-fit ​​protrusions and the plurality of snap-fit ​​grooves 1662 are correspondingly engaged. The portion of the second flexible connecting part 170 that extends out of the support member 160 is bonded to the first support plate 122.

[0044] Specifically, the engagement of the protrusion and slot 1662, along with the cooperation of the through hole 172, effectively prevents the second flexible connection 170 from loosening or falling off inside the support member 160, maintaining connection reliability even under frequent rotation and stress on the support member 160. The bonding between the second flexible connection 170 and the first support plate 122 further enhances the stability of the overall structure, enabling the support member 160 to withstand greater pressure and tension when supporting the tablet computer, without any breakage or loosening at the connection point.

[0045] like Figure 8 and Figure 10 As shown, the second housing 166 and the boss 134 are provided with limiting grooves 1664 at the corresponding positions of their ends. The boss 134 is provided with limiting protrusions 1342 corresponding to the limiting grooves 1664. The limiting protrusions 1342 are engaged in the limiting grooves 1664 to limit the rotation angle of the support member 160 to between 0° and 90°.

[0046] Specifically, when the tablet keyboard cover 100 is closed, the support member 160 rotates to a 90° position (perpendicular to the plane of the keyboard 130 in the width direction). At this time, the limiting protrusion 1342 contacts one side of the limiting groove 1664, restricting the support member 160 from further rotation. When the cover is opened for support, the support member 160 rotates to a 0° position (parallel to the plane of the keyboard 130 in the width direction), and the limiting protrusion 1342 contacts the other side of the limiting groove 1664, preventing the support member 160 from rotating excessively. This limiting structure is simple and reliable, effectively controlling the rotation angle of the support member 160. By limiting the rotation angle of the support member 160 to between 0° and 90°, it ensures that the support member 160 rotates within a reasonable range, satisfying the needs of closing and opening the cover for support, and extending the service life of the support member 160 and the entire cover. At the same time, this limiting design also improves the safety of product use, preventing accidental injury to the user due to abnormal rotation of the support member 160.

[0047] In an optional embodiment of this application, the thickness of the support member 160 is the same as the thickness of the keyboard 130, and the width of the support member 160 is less than or equal to the sum of the thickness of the keyboard 130 and the thickness of the protective shell 150.

[0048] Specifically, in terms of appearance, the design of the support component 160 having the same thickness as the keyboard 130 makes the protective case flatter and more aesthetically pleasing when opened, meeting users' aesthetic requirements for product appearance. Furthermore, during use, the appropriate width of the support component 160 ensures stable support for the tablet. In addition, this size design also considers the rational use of the internal space of the protective case, allowing for a tight fit between the components. For example, when closed, the support component 160 is not too wide, which would affect the overall flatness, thus improving the overall structural compactness and portability.

[0049] This utility model also discloses a tablet computer assembly, including a tablet computer and a tablet keyboard protective case 100 as described above, wherein the tablet computer is fixed within a protective shell 150 on the tablet keyboard protective case 100. This tablet computer assembly has the same structure and beneficial effects as the tablet keyboard protective case 100 in the foregoing embodiments. The structure and beneficial effects of the tablet keyboard protective case 100 have been described in detail in the foregoing embodiments and will not be repeated here.

[0050] It should be understood that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Those skilled in the art can modify the technical solutions described in the above embodiments, or make equivalent substitutions for some of the technical features; and all such modifications and substitutions should fall within the protection scope of the appended claims of this utility model.
