Description

cellphone case

This creation is about a mobile phone case.

As the computing power of today's mobile phones is getting stronger and stronger, the functions are also more and more diverse. In order to realize various functions, there are many different precision devices inside the mobile phone. However, these delicate devices are vulnerable to shock damage. In addition, today's mobile phones are also pursuing large screens or borderless screens, and the screens are also easily damaged by impact. Therefore, in order to protect the mobile phone and avoid the damage caused by the collision with the ground when the mobile phone is accidentally dropped, most users add a protective case to the mobile phone.

In addition to protecting the function of mobile phones, more and more protective cases are advertised as having unique shapes, patterns, or textures. In other words, beauty and fashion have also become an important consideration when purchasing a protective case.

Since there is a lens on the back of the phone, the protective case will form a lens window at the corresponding lens. In the protective shell of the prior art, a lens frame is added to the lens window to increase the shape change of the protective shell. However, in the existing protective case 90, the lens frame 91 is additionally attached to the lens window 92 through the adhesive 93, but the pressure when attaching the lens frame 91 to the lens window 92 often pushes the adhesive 93 out of the lens frame 91 The interface with the lens window 92 (as shown in FIG. 6 ) is not only unsightly, but may also affect the use of the mobile phone lens. On the other hand, since the lens frame 91 is externally attached to the lens window 92 , if the lens frame 91 is attached without being properly aligned, the lens frame 91 will be skewed, which also affects the appearance (as shown in FIG. 7 ).

In view of this, it is an urgent problem to be solved in the industry to propose a better improvement solution.

The main purpose of this creation is to propose a mobile phone protective case. After the lens frame is installed, the adhesive will not protrude out of the lens window, and the lens frame will not be easily skewed, thus making the mobile phone protective case more beautiful.

Therefore, the advantage of this invention is that the glue is extruded during the process of fixing the lens frame to the back cover, but it will not be squeezed to the opening of the lens window, and it can also assist the alignment of the lens frame when gluing the lens frame and the back cover. The lens window on the back cover makes the protective case more neat and beautiful, and also improves the yield rate of the process and the consistency of the quality of the protective case.

In the aforementioned mobile phone protective case, the second abutting surface is farther away from the mobile phone than the first abutting surface.

In the aforementioned mobile phone protective case, the lens frame is formed with: a first fixing surface surrounding the opening of the lens window and fixed on the first bonding surface; and a second fixing surface surrounding the first fixing surface and fixing on the second bonding surface .

In the aforementioned mobile phone protective case: the back cover further forms a first connecting surface, which surrounds the opening of the lens window and connects the first bonding surface and the second bonding surface; and the lens The frame is further formed with a second connecting surface, which surrounds the opening of the lens window and connects the first fixing surface and the second fixing surface, and a gap is formed between the second connecting surface and the first connecting surface .
