The present invention relates to a protective cover.
In general, in order to facilitate the existing tablet computer, the protective cover for the protection machine is often used to simultaneously achieve the support function. However, since the existing protective sleeves are mostly designed such that the protective sleeve can support the tablet computer in different standing states through the folding design between different panels, when the user wants to support the tablet computer through the protective sleeve, it is often necessary to pass through the complicated The folding process can form different support states, which is extremely inconvenient for users who are eager to use the tablet.
In addition, although in the prior art, the tablet can be supported by other auxiliary supports to maintain different support states, but since the auxiliary support is not attached to the tablet device, the user is prone to forget to carry the auxiliary support. The situation of things.
The invention provides a protective cover suitable for an electronic device. The electronic device has a back surface. The protective cover comprises a fixing plate, a first folding plate, a second folding plate and a third folding plate. Fixed plate connection On the back side, and is provided with a first magnetic element. The first folding plate is foldably connected to the fixing plate along an extending direction, and is attached to the back surface with a first attaching force. The second folding plate is foldably connected to the first folding plate in the extending direction, and is attached to the back surface with a second attaching force. The third folding plate is foldably connected to the second folding plate in the extending direction, and is provided with a second magnetic element to be attached to the back surface.
Wherein, when the third folding plate is applied with an external force, the external force, the first gravity provided by the third folding plate and the second gravity provided by the second folding plate cause the third folding plate, The second folding plate and the first folding plate are separated from the back surface, and the third folding plate is folded and attached to the fixing plate by the first magnetic element and the second magnetic element, thereby supporting the electronic device.

Please refer to the eighth figure. The eighth figure shows a schematic plan view of the protective cover provided by the preferred embodiment of the present invention to form another triangular support state to support the electronic device. As shown in the figure, in addition to the triangular support state in which the protective cover 100 can maintain the electronic device 200 in the first standing state, the first folding plate 2 can be retracted in the above-mentioned triangular support state. The auxiliary plate 3 and the second auxiliary plate 4 are attached to the second folding plate 5 in a state of being attached to the placement surface SF, thereby causing the first auxiliary plate 3 to The second auxiliary plate 4 is equivalent to the extension of the second folded plate 5 and forms another triangular support state with the first folded plate 2 and the fixed plate 1 , thereby maintaining the electronic device 200 in a first standing state as described above. The second standing state is more inclined.
Please refer to the ninth figure. The ninth figure shows a schematic plan view of the protective cover provided by the preferred embodiment of the present invention to form another triangular support state to support the electronic device. As shown in the figure, in addition to forming a triangular support state for maintaining the electronic device 200 in the first standing state and the second standing state, the protective cover 100 can also be used to connect the first auxiliary board 3 with the above-mentioned triangular support state. The second auxiliary boards 4 are superposed on each other, so that the fixing board 1, the first folding board 2 and the second folding board 5 form another triangular supporting state, thereby maintaining the electronic device 200 at an inclination angle of the above. a third standing state between the first standing state and the second standing state.
Please refer to the tenth and eleventh drawings. FIG. 10 is a perspective exploded view showing a protective cover and an electronic device according to another preferred embodiment of the present invention. FIG. 11 is a view showing another preferred embodiment of the present invention. The protection kit provided in the example is a three-dimensional schematic diagram of the electronic device.
As shown, a protective cover 100' includes a fixing plate 1', a first folding plate 2', a first auxiliary plate 3', a second auxiliary plate 4', and a second folding plate 5. 'And a third folded plate 6'. The difference between the protective cover 100' and the protective cover 100 is that the third folded plate 6' of the protective cover 100' is attached to one side surface 2012' of an electronic device 200', and the side surface is 2012' is adjacent to the back surface 201', whereby the protective cover 100' is fixed to the fixed area 2011' of the back surface 201' of the electronic device 200' through the fixing plate 1', and is further passed through the third folding board. 6' attached to the side surface 2012' to make the second fold The board 5' and the third folding board 6' are fastened to the electronic device 200'.
In summary, the protective cover of the present invention comprises a fixing plate, a first folding plate, a second folding plate and a third folding plate, and the fixing plate is fixed to the fixing area of the electronic device at the back side.
