## Title
Protective cover for electronic device

## Abstract

A protective cover for an electronic device includes a bottom plate, an integral side wall extending from the edges of the bottom plate. The bottom plate and the integral side wall cooperate to define a concave portion for receiving an electronic device. At least one connecting structure is arranged across the bottom plate and the integral side wall. Each connecting structure divides the protective cover into a first cover and a second cover. One of the first cover or the second cover is able to rotate relative to the other cover via the connecting portion, forming an angle between the first cover and the second cover, whereby the protective cover forms a standing base to support the electronic device at an angle.

FIG. 1 is an isometric view of a protective cover for an electronic device. In at least one embodiment as shown in FIGS. 1 and 2, a protective cover 100 includes, but is not limited to, a bottom plate 21 having a number of edges and an integral side wall 22 extending from the edges of the bottom plate 21. In the embodiment, the bottom plate 21 and the integral side wall 22 cooperate to define a concave portion 23 for receiving an electronic device 200 (as shown in FIG. 4).
In the embodiment, the protective cover 100 further includes at least one connecting structure 30 which is arranged across the bottom plate 21 and the integral side wall 22. Each connecting structure 30 includes a flexible connecting portion 33 formed on the bottom plate 21, each flexible connecting portion 33 has two end portions 331 and 332 (as shown in FIG. 3), and each of the two end portions 331 and 332 forms a slit 34 extending to the integral side wall 22. In the embodiment, the slits 34 adjacent to the connecting portion 33 are symmetrically formed on the two end portions 331 and 332 of the connecting portion 33.
In the embodiment, each connecting structure 30 divides the protective cover 100 into a first cover 31 and a second cover 32. In use, as shown in FIGS. 3 and 4, one of the first cover 31 or the second cover 32 is able to rotate relative to the other cover via the connecting portion 33, forming an angle between the first cover 31 and the second cover 32, whereby the protective cover 100 forms a standing base to support the electronic device 200 at an angle.
In the embodiment, the flexible connecting portion 33 is a flexible crease formed on the bottom plate 21. In the embodiment, the flexible connecting portion 33 is formed to define a groove in an internal surface of the bottom plate 21. The flexible connecting portion 33 is made of thermoplastic polyurethane (TPU) material. One of the first cover 31 and the second cover 32 rotates relative to the other cover by stretching the flexible connecting portion 33.
In the embodiment, each slit 34 is formed to be curved, and at least one protrusion portion 321 and at least one matched recessed portion 322 are thereby respectively formed on the second cover 32 and the first cover 31 and respectively facing the slit 34. In the embodiment, the protrusion portion 321 is configured to abut against a bottom surface of the electronic device 200 when the electronic device 200 is received in the protective cover 100, to limit the rotation scope between the first cover 31 and the second cover 32. Therefore, the electronic device 200 received in the protective cover 100 can be secured at a fixed angle.
In the embodiment, the slit 34 has an L-shaped appearance. In other embodiments, the slit 34 can have an appearance of arc shaped, zigzag shaped, wave shaped, and so on.
In the embodiment, the protective cover 100 includes a connecting structure 30. In one embodiment, as shown in FIGS. 1-4, the connecting structure 30 can be distributed on the protective cover 100 along an oblique direction of the protective cover. In other embodiments, as shown in FIGS. 5-6, the connecting structure 30 can be distributed on the protective cover 100 along a width or a length of the protective cover 100.
In other embodiments, the protective cover 100 includes a number of connecting structures 30. As shown in FIGS. 7-11, each of the connecting structures 30 can be distributed on the protective cover 100 along an oblique angle, or along the width or the length of the protective cover 100. Therefore, one or more of the connecting structures 30 can be selected to allow the protective cover 100 to be formed to support the electronic device 200 in different states, for example, the electronic device 200 can stand at different angles.
The embodiments shown and described above are only examples. Even though numerous characteristics and advantages of the present technology have been set forth in the foregoing description, together with details of the structure and function of the present disclosure, the disclosure is illustrative only, and changes can be made in the detail, including in particular the matters of shape, size, and arrangement of parts within the principles of the present disclosure, up to and including the full extent established by the broad general meaning of the terms used in the claims.
