Description

protective case

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.
