## Title
Protective cover for portable eletronic device

## Abstract

A protective cover for a portable electronic device includes a main body and a plurality of cushioning structures. The main body is configured to receive the portable electronic device. Each cushioning structure includes an elastic body protruding from the main body and a clearance defined between the main body and the elastic body. The elastic body is deformed toward the clearance when the elastic body is impacted.

## Background
BACKGROUND
1. Technical Field
The exemplary disclosure generally relates to protective covers, and particularly to a protective cover for a portable electronic device.
2. Description of Related Art
In order to protect a housing of a portable electronic device, a protective cover can be used. The protective cover protects the portable electronic device from being stained or scraped. However, if the portable electronic device is dropped, the protective cover may not completely cushion the impact, which could cause damage to electronic components of the portable electronic device.
Therefore, there is room for improvement within the art.



BRIEF DESCRIPTION OF THE DRAWINGS
Many aspects of the embodiments can be better understood with reference to the drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the disclosure.
FIG. 1 shows an isometric view of an exemplary embodiment of a protective cover.



DETAILED DESCRIPTION 
FIG. 1 shows an isometric view of an exemplary embodiment of a protective cover 100. The protective cover 100 is used to protect a portable electronic device (not shown), such as a mobile phone, or a tablet computer, for example. The protective cover 100 includes a main body 10 and a plurality of cushioning structures 20. The main body 10 is configured to cover the portable electronic device. The protective cover 100 is preferably made of elastic materials, such as thermoplastic polyurethane(TPU). The main body 10 and the cushioning structures 20 are integrally formed together.
The main body 10 includes a bottom wall 11, a peripheral wall 13 protruding from an peripheral edge of the bottom wall 11, and a receiving groove 15 surrounded by the bottom wall 11 and the peripheral wall 13. The receiving groove 15 receives the portable electronic device. In another embodiment, the bottom wall 11 can be omitted, and the peripheral wall 13 encloses the portable electronic device. The peripheral wall 13 includes a plurality of corners 131, and defines a plurality of through holes 133. The through holes 133 expose keys and interfaces of the portable electronic device.
The cushioning structures 20 are arranged corresponding to the corners 131 of the main body 10. Each cushioning structure 20 includes an elastic body 21 protruding from the main body 10 and a clearance 23 defined between the elastic body 21 and the corner 131. The elastic body 21 can be deformed toward the clearance 23 when the elastic body 21 is impacted, such that a concussion force to the portable electronic device which is received in the protective cover 100 is decreased. The elastic body 21 is positioned at an outer side of a corresponding corner 131. The elastic body 21 is preferably wedge-shaped. In particular, each elastic body 21 includes two elastic arms 211 connected to each other. A distal end of each elastic arm 211 is connected to the corner 131. A width of each elastic arm 211 is gradually decreased from the distal end to the junction between the two elastic arms 211. A plane 213 is defined at the junction between two elastic arms 211 opposite to the corner 131. The plane 213 is configured to increase an area of thrust surface of the cushioning structure 20, to improve the cushion effect of the cushioning structure 20. In the exemplary embodiment, an angle between the two elastic arms 211 is about ninety degrees.
The clearance 23 is surrounded by the corner 131 and the two elastic arms 211. The clearance 23 is configured to facilitate the deformation of the elastic body 21. In the exemplary embodiment, the clearance 23 is a through hole. In another embodiment, the clearance 23 can be a blind hole defined in the elastic body 21.
In use, the portable electronic device is received in the protective cover 100, when the portable electronic device is dropped, the elastic body 21 is impacted and thus is deformed toward the clearance 23 to cushioning concussion exerted on the portable electronic device. Therefore, the electronic components in the portable electronic device can be protected from the concussion.
It is believed that the exemplary embodiments and their advantages will be understood from the foregoing description, and it will be apparent that various changes may be made thereto without departing from the spirit and scope of the disclosure or sacrificing all of its material advantages, the examples hereinbefore described merely being preferred or exemplary embodiments of the disclosure.
