Easy-to-load double-layer mobile phone case

The invention relates to a protective device protective cover, in particular to an easy-to-load double-layer mobile phone protective cover.

In the developed generation of the electronic technology industry, electronic products are full of living environment, among which mobile phones have become an indispensable necessity for people. The rapid development of modern mobile phone technology has not only ended with communication functions, but also has many functions such as camera function, listening to music, sending and receiving emails, connecting social interaction software and entertainment games. Since the mobile phone is operated on the hand, the chance of accidentally dropping the mobile phone is very high. Therefore, most people will add a mobile phone protective case or mobile phone protective cover outside the mobile phone to prevent the mobile phone from being damaged due to falling or scratching. .

The prior art mobile phone case can be divided into a hard shell mobile phone case or a soft shell mobile phone case according to the material. The hard-shell mobile phone case has the advantages of being hard and having good scratch resistance, but the hard-shell mobile phone case is less shock-absorbing, easy to be brittle, and is too hard to be easily loaded and unloaded, and sometimes it is easy to cause scratches on the mobile phone body; Because the hard-shell mobile phone case is relatively hard, the button of the mobile phone body is not well pressed, so that the hard-shell mobile phone case is usually hollowed out in the position corresponding to the button of the mobile phone body, causing dust to accumulate at the button. The soft-shell mobile phone case is better loaded and unloaded and has good buffering effect and is not easy to be cracked, but it is less resistant to scratching. The soft material of the soft-shell mobile phone case is usually thermoplastic polyurethane (TPU), silicone rubber or rubber. In order to make the appearance of the mobile phone itself display, the soft shell mobile phone case mostly uses transparent soft materials, but it is easy to cause yellowing of the transparent soft shell mobile phone case due to ultraviolet rays or acid substances such as hand sweat. , affecting the beauty of the phone case. At present, there is also a double-layer mobile phone case with a transparent soft material in the inner layer and a hard shell material on the outer layer. However, due to its thickness and design limitation, it is difficult to load and unload the mobile phone, and the button portion of the mobile phone is still hollowed out or single. The use of transparent soft materials does not solve the problem of dust on the buttons or yellowing of transparent soft materials.

In view of this, the object of the present invention is to improve various shortcomings of the prior art mobile phone case, and provide a double-layer mobile phone protective case with inner layer buffering, outer layer scratch resistance, good loading and unloading, and convenient pressing and no dust accumulation of the mobile phone button.

In order to achieve the above object, the present invention provides an easy-to-load double-layer mobile phone protective case, which comprises an inner casing and an outer casing.
