Shock-resistant protective shell of portable appliance

Abstract

A shock-resistant protective shell for a portable electric appliance includes a protective shell additionally arranged on a surface of a portable electric appliance and matching the shape of the portable electric appliance, with a buffer body protruding towards an exterior of the protective shell arranged at the corner of the protective shell. A primary buffer axis of the buffer body points to the centroid of the portable electric appliance, or the projection of the primary buffer axis in the principal plane of the electric appliance extends along the angular bisector between two adjacent sides. The buffer body is arranged with a secondary buffer axis arranged perpendicular to the primary buffer axis or perpendicular to the principal plane of the portable electric appliance. The thickness of the buffer body is at least 3 times of the average thickness of the rest parts in the protective shell except for the buffer body.

Description

FIELD OF THE INVENTION[0001]The present invention belongs to the technical field of products associated to portable electric appliances such as cell phones, and relates to a protective shell applied to the surface of a portable electric appliance, in particular to a protective shell that has better shock-resistance performance.BACKGROUND OF THE INVENTION[0002]As the society makes progress, portable electric appliances, such as cell phones, have become indispensable tools increasingly in people's daily life. For example, cell phones with rich functionality and beautiful appearance emerge endlessly nowadays, and many cell phones are expansive. Many people choose to protect their cell phones with a protective shell, to prevent abrasion or scratching of the cell phone surface during daily use. At present, protective shells available in the market for cell phone products are usually made by injection molding from rubber and plastics. These protective shells can protect the cell phone sur...

AI Technical Summary

Benefits of technology

The present invention provides a shock-resistant protective shell for a portable electric appliance with better buffering performance. The protective shell has a buffer body made of a highly elastic material or structure arranged at the corner parts of the shell. This buffer body can be made of a metal material, rubber material, plastic material, or a combination of these materials. The buffer body can be formed integrally with the protective shell or fixed to the shell using anchor connection, adhesive bonding, threaded connection, hinging, fastener connection, snapping connection, or fitting connection. The buffer body can be made of a rubber material, PVC material, polyurethane material, or natural fiber material. The thickness of the protective shell can be increased at the corner parts without compromising its appearance or practicality. The shock-resistant protective shell can greatly improve the buffer stroke, decrease the impact force generated when the portable electric appliance falls to the ground, and improve local shock-resistant performance.

Problems solved by technology

That is the reason why a falling cell phone may be damaged easily.

If there is no protective shell, the buffer stroke will be shorter, and the cell phone may be damaged more easily.

In addition, if the buffer body is not provided with additional damping means or high damping material, the natural damping property of the buffer body is usually too low; consequently, the cell phone will bounce after it hits the ground, and then the cell phone will hit the ground again.
