[0033] Please refer to Figures 1-8The application provides a protective sleeve 1 for a tablet electronic device. The protective sleeve 1 is used for protecting and supporting the tablet electronic device 99. The protective sleeve 1 for the tablet electronic device includes a bottom plate 10 for setting a keyboard 100, a supporting plate 20, and a screen protective cover 30. The bottom plate 10 and the supporting plate 20 are movably connected to the bottom plate 10. The protective sleeve 1 for the tablet electronic device includes a first state, a second state, and a third state, i.e. a closed state, a flat state, and a supporting state. When the protective sleeve 1 for the tablet electronic device is in the closed state, the bottom plate 10, the supporting plate 20, and the screen protective cover 30 are sequentially stacked from bottom to top, and the supporting plate 20 is located between the tablet electronic device 99 and the bottom plate 10. Meanwhile, the screen 990 of the tablet electronic device 99 faces away from the supporting plate 20 and faces the screen protective cover 30, and the keyboard 100 arranged on the bottom plate 10 faces away from the tablet electronic device 99 and faces the supporting plate 20. When the protective sleeve 1 for the tablet electronic device is in the flat state, the screen protective cover 30 is unfolded relative to the bottom plate 10, and the screen protective cover 30 is away from the keyboard 100 arranged on the bottom plate 10. When the protective sleeve 1 for the tablet electronic device is in the supporting state, the supporting plate 20 is lifted to form a corresponding angle to support the tablet electronic device 99. The specific structure of the protective sleeve 1 for the tablet electronic device will be described in detail below to show the implementation process of the first state, the second state, and the third state of the protective sleeve 1 for the tablet electronic device.

[0034] In the embodiment, the exposed areas of the protective sleeve 1 for the tablet electronic device are respectively made of soft materials, such as leather materials and cloth materials.

[0035] The bottom plate 10 includes a front surface 11. The front surface 11 includes a keyboard area 12 for setting a keyboard and a supporting area 13 located on one side of the keyboard area 12. More specifically, the supporting area 13 is located on the side of the keyboard area 12 away from the keyboard area 12 and faces a user. For example, the bottom plate 10 includes a front edge 14 and a rear edge 15 arranged oppositely. The keyboard area 12 is close to the front edge 14, and the supporting area 13 is close to the rear edge 15. The keyboard 100 can be integrally assembled with the bottom plate 10 or fixed to the bottom plate 10.

[0036] The screen protective cover 30 is adapted to the shape of the bottom plate 10. The screen protective cover 30 is movably mounted on the bottom plate 10, so that the screen protective cover 30 can be flipped relative to the bottom plate 10. In the embodiment, the screen protective cover 30 is movably mounted on the side of the bottom plate 10 away from the keyboard area 12. In some feasible embodiments, the screen protective cover 30 can also be movably mounted on the left and right sides of the bottom plate 10. The screen protective cover 30 can be fixed to the bottom plate 10 or detachably mounted on the bottom plate 10.

[0037] The protective sleeve 1 of the flat-panel electronic device further comprises a connecting portion 40 and a limiting block 50. The connecting portion 40 is connected between the bottom plate 10 and the support plate 20, and the support plate 20 and the bottom plate 10 are movably connected together. In the embodiment, the main body portion 401 of the connecting portion 40 is made of a hard material in the inner layer and a soft material in the outer layer, and the two ends of the connecting portion 40 are made of the soft material. The outer layer is wrapped around the inner layer. The two ends of the connecting portion 40 comprise a first end 41 and a second end 42. The first end 41 is fixed to the bottom plate 10, and the second end 42 is fixed to the support plate 20. Since the soft material can be folded and unfolded, the connecting portion 40 can rotate freely relative to the bottom plate 10, and the support plate 20 can rotate freely relative to the bottom plate 10 through the free rotation of the connecting portion 40. For example, the support plate 20 can be translated, lifted at a certain angle, and the like relative to the bottom plate 10. The limiting block 50 is arranged adjacent to the position where the connecting portion 40 is connected to the bottom plate 10, thereby limiting the free range of the support plate 20 relative to the bottom plate 10. More specifically, when the support plate 20 is unfolded relative to the bottom plate 10, the connecting portion 40 is limited by the limiting block 50 to rotate at a certain angle, so that the support plate 20 can only be unfolded to a desired angle relative to the bottom plate 10, rather than 180°. It can be understood that in some feasible embodiments, the connecting portion 40 can also be made of the soft material entirely. In the embodiment, the inner layer is provided with a magnetic member 402, which is used to be attracted to the magnet 210. The magnetic member 402 can be made of a metal material, an alloy material, a ferrite, and the like.

[0038] From the overall angle of the support plate 20, the support plate 20 comprises a first surface 201, a second surface 202 facing away from the first surface 201, and a window 203 arranged at the middle position of the support plate 20. The first surface 201 is used to detachably hold the flat-panel electronic device 99. When the flat-panel electronic device 99 is in the first state, the screen protection cover 30 can be covered on the flat-panel electronic device 99 held on the first surface 201, and the second surface 202 is covered on the front surface to cover the keyboard area 12. When the flat-panel electronic device 99 is in the second state, the screen 990 of the flat-panel electronic device 99 held on the first surface 201 is exposed. When the flat-panel electronic device 99 is in the third state, the support plate 20 is unfolded, and the screen 990 and the keyboard 100 of the flat-panel electronic device 99 held on the first surface 201 are exposed. Since the flat-panel electronic device 99 also has a certain angle relative to the bottom plate 10, the user can operate the flat-panel electronic device 99 through the keyboard 100 in the second state. When the flat-panel electronic device 99 is in the first state and the second state, the connecting portion 40 covers the window 203.

[0039] From the perspective of the components of the support plate 20, the support plate 20 comprises a first support plate 21 and a second support plate 22 rotatably connected with the first support plate 21. When the flat panel electronic device 99 is in the second state, the first support plate 21 and the second support plate 22 are arranged in a flush manner, and both the first support plate 21 and the second support plate 22 are in contact with the flat panel electronic device 99, i.e., the entire first surface 201 serves as a support surface for supporting the flat panel electronic device 99. The first support plate 21 and the second support plate 22 are relatively movable under the action of an external force, so that the first support plate 21 and the second support plate 22 have a corresponding angle therebetween, thereby enabling the protective sleeve 1 of the flat panel electronic device to be in a third state (i.e., a support state) for supporting the flat panel electronic device 99. More specifically, the first support plate 21 and the second support plate 22 have a symmetrical structure. A first notch 210 is arranged at a middle position of an edge of the first support plate 21, and a second notch 220 is arranged at a middle position of an edge of the second support plate 21. The first notch 210 and the second notch 220 jointly form a window 203 when the first support plate 21 and the second support plate 22 are connected. In this embodiment, the first support plate 21 and the second support plate 22 are movably connected by hinges 24, so that the first support plate 21 and the second support plate 22 can be freely rotated between a fully folded state and a flush state under the action of an external force, and remain at the current angle when the external force disappears. The hinges 24 are two in number and symmetrically arranged on both sides of the window 203. The second end 42 of the connecting portion 40 is connected to a position of the second support plate 20 close to the second notch 220, and the connecting portion 40 moves with the second support plate 20 when the flat panel electronic device 99 is in the third state, thereby opening the window 203.

[0040] The first support plate 21 is provided with a magnet 210, which is a magnetic iron. When the protective sleeve 1 of the flat panel electronic device is in the third state, the free end 221 of the second support plate 22 is supported at a position of the support area 1 away from the keyboard area 12, and the free end 211 of the first support plate 21 is located at a position of the support area 1 close to the keyboard area 12, and the connecting portion 40 is attracted to the first support plate 21 by the magnetic member 402 and the magnet 210. When the flat panel electronic device 99 is placed on the support plate 20, only the first support plate 21 is in contact with the flat panel electronic device 99, and the second support plate 21 is relatively rotated to be arranged at an angle with the first support plate 21. At this time, the end of the connecting portion 40 connected to the bottom plate 10 is in contact with the bottom plate 10 under the action of the gravity of the flat panel electronic device 99, thereby jointly providing a support force for supporting the flat panel electronic device 99 with the second support plate 21. That is, the support plate 20 and the connecting portion 40 jointly form a support bracket 60 for supporting the flat panel electronic device 99. That is, the support plate 20 and the connecting portion 40 are collectively referred to as the support bracket 60.

[0041] In the embodiment, the first support plate 21 is not in contact with the bottom plate 10 in the third state, and in some other embodiments, the first support plate 21 can be in contact with the bottom plate 10 in the third state, which is not limited herein. The angle between the first support plate 21 and the second support plate 22 can be adjusted according to actual needs of a user, and the angle between the second support plate 22 and the bottom plate 10 can also be adjusted according to actual needs of the user, that is, the protective sleeve 1 of the tablet electronic device supports the tablet electronic device 99 in an angle-adjustable manner, so that the tablet electronic device 99 can provide a viewing angle that is more fully adapted to the user.

[0042] In the above embodiment, the support plate 20 is arranged between the tablet electronic device 99 and the keyboard 100, so that the screen 990 of the tablet electronic device 99 and the keyboard 100 are not in direct contact, avoiding damage caused by direct contact between the screen 990 and the keyboard 100, and prolonging the service life of the tablet electronic device 99. In addition, the soft material is connected to the bottom plate 10 and the support plate 20 in the embodiment, which greatly reduces the number of hinges used, so that the installation is more gradual, and the support plate 20 is more portable and free. In addition, the first support plate 21 and the second support plate 22 are directly connected by hinges, so that the angle of the first support plate 21 and the second support plate 22 can be freely adjusted within a range, and is not limited to only one or a few angles.

[0043] In the embodiment, the support 60 is formed by the support plate 20 and the connecting portion 40, and in some feasible embodiments, the connecting portion 40 or the support plate 20 can be deformed, so that the deformed support plate is used as the support 60 independently, or the connecting portion 40 is used as the support 60 independently.

[0044] Please refer to Figure 9 In the embodiment, the protective sleeve 1a of the tablet electronic device is different from the protective sleeve 1 of the tablet electronic device in that the support plate 20a is used as the support independently. Specifically, the first support plate 21a and the second support plate 22a in the support plate 20a are relatively opened at corresponding angles in the third state, and the free ends 211a and 221a are supported on the bottom plate 10, so that a triangle is formed between the first support plate 21a, the second support plate 22a and the bottom plate 10, thereby supporting the tablet electronic device 99. It can be understood that in the embodiment, the connecting portion 40a can not have a supporting function, and therefore the connecting portion 40a can be made of soft material.

[0045] Please refer to Figures 10-12In the present embodiment, the protective sleeve 1b of the tablet electronic device is different from the protective sleeve 1 of the tablet electronic device in that the support plate 20b is separately used as a stand. Specifically, one end of the connecting portion 40b is connected to the bottom plate 10b by a hinge, so that the connecting portion 40b can be rotated to a certain angle relative to the bottom plate 10b under the action of an external force, and be fixed at the current angle under the release of the external force. Since the support plate 20b does not need to have a supporting function, the support plate 20b can be integrally provided without the need to be provided in two parts connected by a hinge.

[0046] In the above embodiments, the protective sleeve of the tablet electronic device has multiple states to adapt to different use scenarios. Specifically, in the first state, the bottom plate, the support plate, and the screen protection cover are placed in sequence, the screen protection cover covers the tablet computer, the second surface covers the keyboard area, and direct contact between the screen and the keyboard is avoided; in the second state, the bottom plate, the support plate, and the screen protection cover are unfolded, so that the keyboard and the first surface of the support plate are exposed, facilitating user operation; and in the third state, the support plate can be unfolded to support the tablet computer at a certain angle, and the unique double support plate design of the support plate and the magnetic adsorption structure of the connecting portion make the support more stable and the angle adjustment more flexible. The protection effect on the tablet computer is improved, the problem of direct contact between the screen and the keyboard of the existing protective sleeve when folded, which can cause scratches or wear, is effectively solved, the operation experience of the user in different use scenarios is improved, and the practicality and flexibility of the protective sleeve are improved.

[0047] Obviously, those skilled in the art can make various modifications and variations to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalent technologies, the present application also intends to include these modifications and variations.

[0048] The above only lists the preferred embodiments of the present application, and of course cannot limit the scope of the rights of the present application, so equivalent changes made according to the claims of the present application still belong to the scope covered by the present application.
