Description
Technical Field
The utility model relates to an electronic equipment accessory technical field such as cell-phone, concretely relates to protective housing/protective sheath device of foldable electronic product.
Background
In order to protect fragile electronic products such as mobile phones from being disorderly and damaged, people usually wear protective cases (or called protective cases) on the electronic products. For the protective sleeve of a common tablet mobile phone, the current technology is perfected, a good protection effect can be achieved, and meanwhile, normal use is basically not influenced. However, with the push-out of foldable tablet phones and the new trend of development in recent years, since the unit price of the foldable tablet phone is high and there is a gap at the hinge bending part during folding, the foldable tablet phone is easily damaged by dust, sand, water drops and the like, and thus the foldable tablet phone needs to be protected by a protective cover more than the traditional phone.
In addition, the folding tablet mobile phone is also the same as the traditional mobile phone, and a protective sleeve is needed to prevent the mobile phone shell from being scratched, worn or even cracked due to direct touch with foreign objects, so that the functions of falling prevention, shock resistance and the like can be provided. Although various functional mobile phone protective cases are available in the market, such as hard plastic protective cases, soft plastic protective cases, waterproof protective cases, anti-falling protective cases, and so on. However, the conventional protective case structure cannot be matched with the folding and bending functions of a folding tablet phone, so that the current protective case cannot meet the requirements of consumers.
Therefore, people design a plurality of protective sleeves specially for foldable tablet electronic products, such as the scheme disclosed in the utility model CN202121622933, which sets up a hinge protector between a front protective case and a rear protective case, and the hinge protector can effectively protect the hinge bending part of a foldable screen mobile phone, but because the hinge protector needs to be taken down when the mobile phone is unfolded, the hinge protector needs to be installed again when the mobile phone is folded, so that the use is quite troublesome, and the consumer acceptance is not high.
As disclosed in CN202121154776, the connecting member comprises a plurality of hollow parts and a connecting part connected between the hollow parts, the connecting part comprises a storage state and an extended state, and the plurality of hollow parts are disposed on the connecting part, so as to better fit the outer side surface of the folded part of the foldable terminal. Although the mode can improve the tensile deformation capability of the soft rubber material, the following problems exist: when the mobile phone is folded, the connecting part is coated on the hinged bent part of the mobile phone, so that overlarge restoring force can press the hinged bent part, the mobile phone is easily damaged, and the folding performance of the mobile phone is influenced; meanwhile, the connecting part is in a high-tension state during folding and is easy to break. And the hollow part is directly exposed, so that the dustproof and waterproof capabilities of the protective sleeve can be reduced.
There is also a solution as disclosed in patent CN202020173398, which utilizes a telescopic shell combined with an upper shell and a lower shell to form a folding protective shell, and a sealing area can seal a foldable portion of an electronic device, so as to achieve waterproof and impurity-proof effects on the electronic device and ensure the security of the electronic device. Although the structure seems reasonable, the practicability is not high, because the elasticity of the fold structure is gradually lost due to easy material fatigue and relaxation after the fold structure is opened and closed for many times; and the combination strength of the telescopic shell and the upper and lower shells is not high, and the thickness of the telescopic shell is quite thin, so that the manufacturing difficulty is high, and the structural strength is low. Other existing schemes are not described in detail.
