Benefits of technology

[0011]In most cases, when a portable electric appliance falls to the ground, for example, when a cell phone falls from a desktop or hand to the ground, a corner part will hit the ground first. Existing protective shells for cell phones in the market are usually rubber or plastic protective shell in uniform thickness, which provide a very limited buffering effect, owing to the limited thickness of protective shell. If the thickness of the protective shell is increased uniformly, the protective shell will become very unhandy. Such protective shells can't be accepted by fashionistas and are not economic. In the present invention, by arranging convex buffer bodies at the corner parts of a protective shell, the shock-resistant performance of the protective shell and the protected portable electric appliance is greatly improved, while the cost is not increased significantly and the appearance is not compromised. Such a protective shell can meets the requirements for practicability, economic efficiency, and safety.

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 a

embodiment 1

[0045]In view that the existing portable electric appliances are diverse in type and their shells are diverse in shape, it is impossible to described them in detail one by one; therefore, hereunder the technical principle of the present invention will be detailed exemplarily in the case of a shock-resistant protective shell for a cell phone. As shown in FIGS. 1, 2, 3, and 4, the shock-resistant protective shell for a portable electric appliance according to the present invention (specifically, a shock-resistant protective shell for a cell phone) comprises a protective shell 1 that matches the shape of a cell phone (not shown). The protective shell 1 is made of an elastic PVC material, and the eight corner parts of the protective shell are provided respectively with a buffer body 2 that protrudes towards the exterior of the protective shell, and the buffer body 2 is in a shape that is spherical in part; the buffer body 2 can also be made of an elastic PVC material, and is integrally ...

embodiment 2

[0051]In the present invention, the buffer body can not only be in diverse shapes but also in different structures. In the shock-resistant protective shell for a portable electric appliance shown in FIG. 5 according to the present invention, the difference from the embodiment 1 lies in: the protective shell 1 is made of a rigid plastic material, and is provided in it with a helical spring structure consisting of a protective enclosure 4 and a helical spring 5, wherein, the protective enclosure is made of stainless steel plates, the helical spring 5 is made of a stainless steel wire, the upper part of the helical spring 5 is fixed to the protective enclosure 4 by welding, the lower end of the helical spring 5 is anchored in the protective shell 1, and the axis direction of the helical spring 5 is arranged in the primary buffer axis direction of the buffer body.

embodiment 3

[0055]In the shock-resistant protective shell for a portable electric appliance shown in FIG. 6 according to the present invention, compared with the embodiment 2, there are differences as follows. The buffer body is in a flexural spring structure consisting of a protective enclosure 4 and a flexural spring 6. Moreover, the protective enclosure 4 is made of a plastic material; the flexural spring 6 is made of a steel spring wire; the upper part of the flexural spring 6 is fixed in the protective enclosure 4; the lower end of the flexural spring 6 is anchored in the protective shell 1; and the maximum deformation direction of the flexural spring 6 is arranged in the primary buffer axis direction of the buffer body.

[0056]Similar to the embodiment 2, the flexural spring structure can also be made of a metal material, or a rubber material, or a polyurethane material, or a plastic material, or any combination of these above, not limited to the materials mentioned in this document, and ca...

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...
