[0037] To provide a clearer and more accurate understanding of the content of this application, it will be described in detail below with reference to the accompanying drawings. The drawings in the specification show examples of the embodiments of this application, in which the same reference numerals represent the same components. It can be understood that the scale shown in the drawings of the specification is not the actual scale of the implementation of this application, and it is only for illustrative purposes and is not drawn according to the original size.

[0038] Please refer to Figures 1 - 8 , this application provides a protective cover 1 for a flat electronic device. It is used to protect and support the flat electronic device 99. The protective cover 1 of the flat electronic device includes a bottom plate 10 for setting a keyboard 100 at one end, a support plate 20, and a screen protection cover 30. The bottom plate 10 and the support plate 20 are both movably connected relative to the bottom plate 10. The protective cover 1 of the flat electronic device includes a first state, a second state, and a third state, namely, a closed state, a flat state, and a supported state. Among them, when the protective cover 1 of the flat electronic device is closed, from bottom to top, the bottom plate 10, the support plate 20, and the screen protection cover 30 are stacked in sequence, and the support plate 20 is located between the flat electronic device 99 and the bottom plate 10. At the same time, the screen 990 of the flat electronic device 99 faces away from the support plate 20 and towards the screen protection cover 30, and the keyboard 100 provided on the bottom plate 10 faces the side of the support plate 20 that is away from the flat electronic device 99. When the protective cover 1 of the flat electronic device is in the flat state, the screen protection cover 30 is unfolded relative to the bottom plate 10, and the screen protection cover 30 is away from the keyboard 100 provided on the bottom plate 10. When the protective cover 1 of the flat electronic device is in the supported state, the support plate 20 is lifted at a corresponding angle to support the flat electronic device 99. The specific structure of the protective cover 1 of the flat 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 cover 1 of the flat electronic device.

[0039] In this embodiment, the exposed areas of the protective cover 1 of the flat electronic device are made of soft materials, such as leather materials and cloth materials.

[0040] The bottom plate 10 includes a front surface 11. The front surface 11 includes a keyboard area 12 for setting a keyboard and a support area 13 located on one side of the keyboard area 12. More specifically, the support area 12 is located on the side of the keyboard area 12 away from the side facing the user operation of the keyboard area 12. For example, the bottom plate 10 includes a front edge 14 and a rear edge 15 which are oppositely arranged. The keyboard area 12 is close to the front edge 14, and the support area 13 is close to the rear edge 15. The keyboard 100 can be detachably assembled with the bottom plate 1 as a whole, or can be fixed to the bottom plate 10 as a whole.

[0041] The screen protection cover 30 is adapted to the shape of the bottom plate 10. The screen protection cover 30 is movably mounted on the bottom plate 10 so that the screen protection cover 30 can be flipped relative to the bottom plate 10. In this embodiment, the screen protection 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 protection cover 30 can also be movably mounted on the left and right sides of the bottom plate 10. The tablet protection cover 30 can be fixed to the bottom plate 10 or can be detachably mounted on the bottom plate 10.

[0042] The protective cover 1 of the tablet electronic device further includes 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, so that the support plate 20 and the bottom plate 10 are movably connected together. In this embodiment, the main body portion 401 of the connecting portion 40 is arranged in such a way that the inner layer is made of a hard material and the outer layer is made of a soft material, and both ends of the connecting portion 40 are made of a soft material. The outer layer wraps the inner layer. The two ends of the connecting portion 40 include 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 by rotating freely with the connecting portion 40. For example, the support plate 20 can translate relative to the bottom plate 10, lift a certain angle, etc. The limiting block 50 is arranged adjacent to the position where the connecting portion 40 is connected to the bottom plate 10, thereby restricting the freedom of the support plate 20 relative to the bottom plate 10 within a certain range. 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 and can only rotate a certain angle, so that the support plate 20 can only be unfolded relative to the bottom plate 10 to a desired angle, rather than 180°. It can be understood that in some feasible embodiments, the connecting portion 40 can also be entirely made of a soft material. In this embodiment, a magnetic member 402 is provided inside the inner layer, and the magnetic member 402 is used to attract the magnet 210. The magnetic member 402 can be made of a metal material, an alloy material, a ferrite, etc.

[0043] From the overall perspective of the support plate 20, the support plate 20 includes a first surface 201, a second surface 202 facing away from the first surface 201, and a window 203 disposed at the middle position of the support plate 20. The first surface 201 is used to separably hold the flat electronic device 99. When the flat electronic device 99 is in the first state, the screen protector 30 can cover the flat electronic device 99 placed on the first surface 201, and the second surface 202 covers the front to cover the keyboard area 12. When the flat electronic device 99 is in the second state, the screen 990 of the flat electronic device 99 placed on the first surface 201 is exposed. When the flat 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 electronic device 99 placed on the first surface 201 are exposed. Since the flat electronic device 99 still has a certain angle relative to the bottom plate 10, the user can operate the flat electronic device 99 through the keyboard 100 in the second state. When the flat electronic device 99 is in the first state and the second state, the connecting portion 40 covers the window 203.

[0044] From the perspective of the components of the support plate 20, the support plate 20 includes a first support plate 21 and a second support plate 22 rotatably connected to the first support plate 21. When the flat electronic device 99 is in the second state, the first support plate 21 and the second support plate 22 are flush with each other, and both the first support plate 21 and the second support plate 22 are in contact with the flat electronic device 99, that is, the entire first surface 201 serves as a support surface for supporting the flat electronic device 99; the first support plate 21 and the second support plate 22 move relative to each other under an external force so that there is a corresponding angle between the first support plate 21 and the second support plate 22, thereby enabling the protective cover 1 of the flat electronic device to be in the third state (i.e., the support state) to support the flat 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 provided at the middle position of one edge of the first support plate 21, and a second notch 220 is provided at the middle position of one edge of the second support plate 21. When the first support plate 21 and the second support plate 22 are connected, the first notch 210 and the second notch 220 together form the window 203. In this embodiment, the first support plate 21 and the second support plate 22 are movably connected by a hinge 24, so that the first support plate 21 and the second support plate 22 can freely rotate between the fully folded state and the flush state under an external force, and when the external force disappears, they remain at the current angle. There are two hinges 24, and the two hinges 24 are symmetrically disposed 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 near the second notch 220. When the flat electronic device 99 is in the third state, the connecting portion 40 moves along with the movement of the second support plate 20, thereby opening the window 203.

[0045] A magnet 210 is provided on the first support plate 21, and the magnet 210 is a magnet. When the protective cover 1 of the flat electronic device is in the third state, the free end 221 of the second support plate 22 supports at a position on the support area 1 away from the keyboard area 12, the free end 211 of the first support plate 21 is located at a position on the support area 1 close to the keyboard area 12, and the connecting portion 40 is attracted to the magnet 210 by the magnetic member 402 and adsorbed on the first support plate 21. When the flat electronic device 99 is placed on the support plate 20, only the first support plate 21 contacts the flat electronic device 99, and the second support plate 21 rotates relatively and is arranged at an angle with the first support plate 21. At this time, one end of the connecting portion 40 connected to the bottom plate 10 abuts against the bottom plate 10 under the gravity of the flat electronic device 99, so as to jointly provide a supporting force for supporting the flat electronic device 99 with the second support plate 21. That is to say, the support plate 20 and the connecting portion 40 jointly form a bracket 60 for supporting the flat electronic device 99. That is, the support plate 20 and the connecting portion 40 are collectively referred to as the bracket 60.

[0046] In this embodiment, the first support plate 21 and the bottom plate 10 do not contact in the third state. In some other embodiments, the first support plate 21 and the bottom plate 10 may also contact 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 the actual needs of the user, and the angle between the second support plate 22 and the bottom plate 10 can also be adjusted according to the actual needs of the user. That is, the protective cover 1 of the flat electronic device supports the flat electronic device 99 in an angle-adjustable manner, so that the flat electronic device 99 can provide a viewing angle more comprehensively adapted to the user.

[0047] In the above embodiment, a support plate 20 is provided between the flat electronic device 99 and the keyboard 100, so that the screen 990 of the flat electronic device 99 and the keyboard 100 do not directly contact, avoiding damage caused by direct contact between the screen 990 and the keyboard 100, and prolonging the service life of the flat electronic device 99. In addition, in this embodiment, the bottom plate 10 and the support plate 20 are connected by a soft material, greatly reducing the number of hinges used, so that the installation is more gradual, and the movement of the support plate 20 is more convenient and free. In addition, the first support plate 21 and the second support plate 22 are directly connected by a hinge, so that the angle between the first support plate 21 and the second support plate 22 can be freely adjusted within the adjustable range, rather than being limited to only being adjusted to one or several angles.

[0048] In this embodiment, the bracket 60 is jointly formed by the support plate 20 and the connecting portion 40. In some feasible embodiments, the connecting portion 40 or the support plate 20 can also be deformed so that the deformed support plate independently serves as the bracket 60, or the connecting portion 40 independently serves as the bracket 60.

[0049] Please refer toFigure 9 , in this embodiment, the difference between the protective cover 1a of the flat-panel electronic device and the protective cover 1 of the flat-panel electronic device is that the support plate 20a serves as a bracket alone. Specifically, in the third state, the first support plate 21a and the second support plate 22a in the support plate 20a open at a corresponding angle relative to each other, and the free ends 211a and 221a both support on the bottom plate 10, so as to form a triangular positioning among the first support plate 21a, the second support plate 22a, and the bottom plate 10, thereby supporting the flat-panel electronic device 99. It can be understood that in this embodiment, since the connecting portion 40a does not need to have a supporting function, the connecting portion 40a can also be entirely made of a flexible material.

[0050] Please refer to Figures 10 - 12 , in this embodiment, the difference between the protective cover 1b of the flat-panel electronic device and the protective cover 1 of the flat-panel electronic device is that the support plate 20b serves as a bracket alone. Specifically, one end of the connecting portion 40b is hinged to the bottom plate 10b, so that the connecting portion 40b can rotate relative to the bottom plate 10b to a certain angle under an external force and be fixed at the current angle when the external force is released. Since the support plate 20b does not need to have a supporting effect, the support plate 20b can be integrally provided and does not need to be provided in two parts connected by two hinges.

[0051] In the above embodiments, the protective cover of the flat-panel electronic device has multiple states at the same time to adapt to different usage scenarios. Specifically, in the first state, the bottom plate, the support plate, and the screen protection cover are stacked in sequence, the screen protection cover covers the tablet computer, and the second surface covers the keyboard area, avoiding direct contact between the screen and the keyboard; 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 at a certain angle to support the tablet computer, 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. It improves the protection effect on the tablet computer, effectively solves the problem that the screen and the keyboard of the existing protective cover are in direct contact and are easily scratched or worn when folded, and also improves the user's operation experience in different usage scenarios, improving the practicality and flexibility of the protective cover.

[0052] Obviously, those skilled in the art can make various changes and modifications to this application without departing from the spirit and scope of this application. Thus, if these modifications and variations of this application fall within the scope of the claims of this application and their equivalent technologies, this application also intends to include these changes and modifications.

[0053] The above are only the preferred embodiments of this application, and of course, the scope of the rights of this application cannot be limited by this. Therefore, the equivalent changes made according to the claims of this application still fall within the scope covered by this application.
