Dual layer mobile phone protective shell capable of being assembled and disassembled easily

Abstract

The invention relates to a dual layer mobile phone protective shell capable of being assembled and disassembled easily. The mobile phone protective shell comprises a protection shell, which comprisesan inner shell and an outer shell. The inner shell is flexible. The shape of the inner shell is corresponding to the shape of the outer shell. The inner shell is arranged in the outer shell. The outershell comprises at least one button part. At least one button part is arranged in one long lateral surface of the outer shell. At least one button part comprises a connection terminal and a hollow part. A part of the hollow part encloses the connection terminal. The provided dual layer mobile phone protective shell has the advantages that the inner layer has a buffering function, the outer layeris scratch resistant, the disassembly and assembly are easy, the button is convenient to press, and dust stratification is avoided.

Description

technical field [0001] The invention relates to a mobile device protective case, in particular to a double-layer mobile phone protective case that is easy to assemble and disassemble. Background technique [0002] In the era when the electronic technology industry is developed, electronic products are flooding the living environment, among which mobile phones have become an indispensable necessity for people. Modern mobile phone technology has developed rapidly and diversified, not only with communication functions, but also with multiple functions such as camera functions, listening to music, sending and receiving emails, connecting to social interaction software, and entertainment game effects. Since the mobile phone is operated in the hand, the probability of accidentally dropping the mobile phone is very high, so most people will add a mobile phone protective case or mobile phone protective cover on the outside of the mobile phone to prevent the mobile phone from being d...

Problems solved by technology

The hard shell mobile phone case is relatively hard and has the advantages of good scratch resistance, but the hard shell mobile phone case is less shock-absorbing, easy to be brittle, and because it is too hard, it is not easy to install and disassemble, and sometimes it is easy to cause scratches on the mobile phone body; and because of the hard shell The hard phone case makes it difficult to press the buttons on the phone body, so that the hard shell phone case is usually hollowed out in the corresponding position of the button on the phone body, causing dust to accumulate on the buttons

The soft shell mobile phone case is easy to load and unload, has a good cushioning effect and is not easy to crack, but is less scratch-resistant; the soft material of the soft shell mobile phone case is usually thermoplastic polyurethane (thermoplastic polyurethane, TPU), silicone or rubber. Among them, in order to show the appearance of the mobile phone itself, most of the soft-shell mobile phone cases use transparent soft materials, but it is easy to cause yellowing of the transparent soft-shell mobile phone case due to exposure to ultraviolet rays or exposure to acidic substances such as hand sweat, which affects beautiful phone case

At present, there are also double-layer mobile phone cases that combine the inner layer with a transparent soft material and the outer layer with a hard shell material. However, due to its thickness and design limitations, it is difficult to install and disassemble the mobile phone, and the key parts of the mobile phone are still hollowed out. The use of transparent soft materials alone cannot solve the problem of dust accumulation on the buttons or yellowing of transparent soft materials
