FIG. 1 is a diagrammatic view of a protective cover. In the embodiment as shown in FIG. 1, a protective cover 100 is configured for receiving an electronic device 200 (as shown in FIG. 2). In the embodiment, the protective cover 100 includes a first shell 31 and a second shell 32 which cooperate to receive the electronic device 200. In the embodiment, the protective cover 100 further includes a rigid frame 33 which is mounted on the second shell 32.
FIG. 2 shows that the protective cover 100 also acts as a holder for supporting the electronic device 200 at a viewing angle. In the embodiment, the second shell 32 equipped with the rigid frame 33 can be rotatable relative to the first shell 31, to form an angle between the first shell 31 and the second shell 32, whereby the protective cover 100 forms a holder to support the electronic device 200 at a viewing angle on a supporting surface (not shown), preferably at an angle of 45 degrees.
In the embodiment, the first shell 31 configured to hold and protect the electronic device 200 on at least three sides, and the second shell 32 is rotatably connected along a diagonal hinge 40 to the first shell 31 to define at least first and second orientations relative to the first shell 31. In the embodiment, the first orientation is parallel with the first shell 31, and the second shell 32 is configured to hold and protect the electronic device 200 on at least two sides. The second orientation is rotated about the diagonal hinge 40, and the second shell 32 acts as a back stand which is configured to, via a combination with the first shell 31, support the electronic device 200 at a viewing angle when the holder is on a supporting surface. In the embodiment, when the holder is on the supporting surface, a side of the first shell 31 and a corner of the second shell 32 provide the contact with the supporting surface to support the holder.
In the embodiment, the first shell 31 and the second shell 32 are made of flexible material, such as thermoplastic polyurethane material, so as to provide a cushion to protect the electronic device 200 against physical shocks.
In the embodiment, the rigid frame 33 is made of rigid material, such as polycarbonate material, to provide sufficient structural strength for the protective cover 100 to support the electronic device 200 when the electronic device 200 is in use.
FIG. 3 shows that the second shell 32 defines a concavity 321 on an external surface 324 thereof for receiving the rigid frame 33.
In the embodiment, the rigid frame 33 includes a number of edges 334 and a number of convex portions 331 extending from the edges 334 of the rigid frame 33. FIG. 4 shows that the second shell 32 further defines a number of recessed portions 322 on the side wall of the concavity 321 for receiving the number of convex portions 331 of the rigid frame 33.
In the embodiment, each convex portion 331 includes a pair of hooks 332 extending from two sides of a free end portion of the convex portions 331 towards adjacent convex portions 331. In the embodiment, each hook 332 is configured to abut against the interior of the recessed portion 322 when the convex portions 331 are received in the recessed portions 322, to prevent the rigid frame 33 separating from the second shell 32.
In the embodiment, the second shell 32 further includes at least one protrusion 323 extending from the interior of the recessed portion 322, and the convex portion 331 defines at least one hole 333 for insertion of the protrusion 323, in order to mount the rigid frame 33 firmly in the concavity 321 of the second shell 32.
With such structure, the protective cover 100 includes soft shell for absorbing physical shocks when, for example, the electronic device 200 falls to the floor, and a rigid frame for providing sufficient structural support for the protective cover 100 to support the electronic device 200 when the electronic device 200 is in use.
At least part of the outer boundaries of shells 31 and 32 may be made of rubber or other high friction material so as to grip the supporting surface on which the protective cover 100 is placed in FIG. 2. This high friction material will grip the supporting surface so that the first shell 31 and the second shell 32 do not slide apart from each other.
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.
