(57) ABSTRACT 

The present invention relates to a protective mask of mobile 

phone comprising an upper cover body and a lower cover 

body. The upper and lower cover bodies can be joined with 

a front and a rear phone housing of a mobile phone, 

respectively, to effectively prevent abrasion of the mobile 

phone due to carelessness of a user, thereby preventing 

ill-favored scars on the mobile phone. Therefore, the deterioration of the quality of the mobile phone and the fall of 

its value can be avoided. Moreover, trend and fashion of the 

mobile phone can be achieved without the need ofreplacing 

the mobile phone. Therefore, waste of money can be 

avoided, and economic burden to the user can be lessened.

RELATED APPLICATIONS 

This application is a continuation of U.S. patent applica- 5 

tion Ser. No. 11/673,237, filed Feb. 9, 2007, now U.S. Pat. 

No. 7,941,195, which (i) is a continuation application of 

U.S. patent application Ser. No. 09/888,488, filed Jun. 26, 

2001, now U.S. Pat. No. 7,194,291, and (ii) claims priority 

to Chinese Patent Application No. CN00252902.5, filed 10 

Nov. 17, 2000, the contents of which are incorporated herein 

by reference. 

FIELD OF THE INVENTION 

The present invention relates to a protective mask of 

mobile phone and, more particularly, to an assembly structure used in a mobile phone. 

BACKGROUND OF THE INVENTION 

15 

20

printed on the upper and lower cover bodies. The upper and 

lower cover bodies can sheathe a mobile phone therein. A 

gap, cavities, and slots corresponding to an antenna, an 

earphone cavity, an incoming-call informing light and so on 

of the mobile phone are disposed on the lower cover body 

so that a user can successfully receive a call and use various 

kinds of functions and settings of the mobile phone. 

The various objects and advantages of the present invention will be more readily understood from the following 

detailed description when read in conjunction with the 

appended drawings, in which: 

BRIEF DESCRIPTION OF THE DRAWINGS 

FIG. 1 is a perspective view of a prior art mobile phone; 

FIG. 2 is a diagram showing the use state of a prior art 

mobile phone; 

FIG. 3 is an exploded perspective view of the present 

invention and a mobile phone; 

FIG. 4 is a perspective view of the present invention 

assembled with a mobile phone; 

FIG. 5 is a cross-sectional view of the present invention 

assembled with a mobile phone; 

FIGS. 1 and 2 show the structure of a prior art mobile 

phone. The outer look of the structure is approximately a 

rectangular parallelepiped comprising a front phone housing 

and a rear phone housing. One end of the front phone 

housing 11 is pivotally joined with one end of the rear phone 

housing 12, as shown in FIG. 2. An antenna 121 is disposed 

FIG. 6 is a diagram showing the use state of the present 

25 invention assembled 10 with a mobile phone; and 

on the rear phone housing 12. A mobile phone 10 is formed 

after assembling the front and rear phone housings 11 and 

12. The mobile phone 10 can be used for receiving a call, 30 

dialing a telephone number, making a call, displaying messages, and setting functions. 

However, because the front and rear phone housings 11 

and 12 of the mobile phone 10 are very smooth and delicate, 

abrasion may easily arise due to carelessness of a user so as 35 

to generate ill-favored scars thereon, resulting in the deterioration of the quality of the mobile phone and the fall of 

its value. 

Moreover, the design of the mobile phone 10 tends to be 

more and more diversified in consideration of trend and 40 

fashion. The user usually spends a lot of money to change 

the mobile phone 10 to adhere to the fashion, resulting in 

waste of money. 

Accordingly, the above mobile phone structure has inconvenience and drawbacks in practical installation and use. 45 

The present invention aims to resolve the problems in the 

prior art.
