Abstract

A protective cover includes a base plate, an integral frame vertically extending from the edge of the base plate, and a shock absorption structure. The base plate and the integral frame cooperate to form a concave portion, which matches with a portable device and is configured to receive the portable device. The shock absorption structure includes a plurality of recesses formed on the internal surface of the integral frame and/or the base plate. The recesses are configured to entrap air therein when the portable device is received in the concave portion and the internal surface of the integral frame and the base plate are fully in contact with the surfaces of the portable device, so as to provide a cushion to protect the portable device against shock.

First claim

What is claimed is:

1. A protective cover comprising:
a base plate;
an integral frame vertically extending from the edge of the base plate, wherein the base plate and the integral frame cooperate to form a concave portion, which matches with a portable device and is configured to receive the portable device; and
a shock absorption structure comprising a plurality of recesses formed on the internal surface of the integral frame, and a plurality of arc grooves formed on the outside surface of the integral frame, each arc groove being located between two of the plurality of recesses, which are adjacent to each other, wherein the plurality of recesses are configured to provide a cushion to protect the portable device against shock;
wherein the plurality of recesses includes recesses that are formed at corners of the integral frame, and a recess that is formed where buttons are positioned;
wherein the integral frame comprises four frames, the four frames comprise a left frame, a right frame, a top frame, and a bottom frame;
wherein the recesses that are formed at the corners of the integral frame comprises a first recess that is formed at a left top corner, a second recess that is formed at a right top corner, a third recess that is formed at a left bottom corner, and a fourth recess that is formed at a right bottom corner;
wherein the plurality of arc grooves comprises a first groove formed on the outside surface of the top frame, and a second groove formed on the outside surface of the bottom frame, the first groove is located between the first recess and the second recess, and the second groove is located between the third recess and the fourth recess;
wherein the plurality of recesses are configured to entrap air therein when the portable device is received in the concave portion and the internal surface of the integral frame and the base plate are in contact with the surfaces of the portable device, so as to provide a cushion to protect the portable device against shock.

2. The protective cover as described in claim 1 , further comprising an integral brim extending inward from the edge of the integral frame, wherein the integral brim is configured to hold edges of the portable device to prevent the portable device from coming out of the concave portion.
