[0005] The above invention purpose of the present application is realized by the following technical scheme:

[0006] a back plate;

[0007] a rotating part;

[0008] a cover, which is rotatably arranged between the back plate and the rotating part. The cover is sequentially provided with a first folding part, a second folding part, a third folding part and a fourth folding part from a position away from the rotating part to a position close to the rotating part. The cover is provided with a communication part. The first folding part, the second folding part, the third folding part and the fourth folding part are connected through the communication part and radially distributed with the communication part as a shooting point. The cover is provided with a first supporting module between the first folding part and the fourth folding part, a second supporting module between the first folding part and the second folding part, a third supporting module between the second folding part and the third folding part, and a fourth supporting module between the third folding part and the fourth folding part. The shape of the first supporting module is a right trapezoid, and the shapes of the second supporting module, the third supporting module and the fourth supporting module are all triangles. The cover forms a first folding frame body or a second folding frame body by folding. The first folding frame body and the second folding frame body can provide support for the flat panel computer when the flat panel computer is placed at any side edge.

[0009] By adopting the technical scheme, different combinations and folding modes of the first support module, the second support module, the third support module and the fourth support module on the surface cover can provide support for the tablet computer at multiple inclination angles, meet the use requirements of the user in different scenarios, and the first folding frame body and the second folding frame body formed by folding can make the tablet protective cover adapt to the case that the tablet computer is placed at any side edge, greatly enhance the flexibility and adaptability of the tablet protective cover, and improve the user experience.
