  • the beautiful glass and metal back shell that can never touch the user's palm, and then the protective cover is inserted.
  • the difference between directly using the plastic back shell: redundant The new glass and metal increase the weight of the mobile phone, and the mobile phone protective cover makes the mobile phone thicker and wider, which seriously reduces the feel of the mobile phone.
  • the user needs the freedom to choose the shell material. If the manufacturer can't provide it, at least the beautiful glass and metal back shell can really play a role and improve the user's feel. However, if it is used without a mobile phone case, the toughened film that is not large enough to fit can not fully protect the front screen of the mobile phone, and the risk of broken screen becomes extremely high. Even the common TPU mobile phone case cannot fully protect the screen. One hit will cause a broken screen.

  • the former can extend outward from the side of the protective cover adjacent to the four corners of the display screen ("inner” is the space for the protective cover to accommodate portable devices, and “outward” extends toward the direction of the user), so that when the phone falls or is impacted by other external forces At this time, the four corners of the display screen will not be impacted, unless the extension part is greatly deformed, so that the four corners of the display screen are also impacted by the ground/impacting object.
  • the impact force can be fixed by the buckle of the portable device through the protective cover and transferred to the more slamming device casing, or it can be buffered by the deformation of the elastic material.
  • the latter can extend horizontally (parallel to the display screen of the portable device) where the sides of the protective cover are adjacent to the four corners of the display.
  • the extended part can be made of elastic material, so that when the phone is dropped or is impacted by other external forces, the four corners of the display are not Will be directly impacted, and the elasticity of the extension can be cushioned to increase the impact time. According to the law of conservation of momentum, for the same momentum, the longer the impact time, the smaller the force generated by the impact and the smaller the damage to the four corners of the display.
