Definitions

  • the present invention relates to a light and thin vertical protective cover for portable equipment, in particular to a protective cover that reduces the probability of screen breakage due to equipment falling or other external forces by strengthening the protection of the corners of the device screen.

  • the US invention patent US 9,553,629 describes a set of protective clips that can be firmly installed on the edges and corners of portable electronic devices without the help of tools or glue.
  • fixed protection The space occupied by the folder is too large, which will affect the user's use.
  • the back shells of modern mobile phones are generally made of glass, metal and other more beautiful materials, but they cannot be used without wearing a cover. This is a bad wind brought by Apple, adding some beautiful but meaningless structures.
  • 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 phone, and the risk of broken screen becomes extremely high. Even the common TPU phone case cannot fully protect the screen. When the four corners of the phone display One hit will cause a broken screen.
  • the mobile phone protective film can reduce the risk of broken screen to a certain extent.
  • the common protective film is usually much smaller than the mobile phone screen. The effect of scraping. Then, a mobile phone case that can fully protect the screen can circumvent the manufacturing accuracy problem.
  • the embodiment of the present invention provides a protective cover:
  • the protective cover includes a bottom surface and a side surface, and the corners of the side have an extended structure
  • the extended structure can be perpendicular to the screen of the portable device
  • the extended structure can fit the device screen in the corner of the adjacent side of the portable device
  • the bottom of the protective cover has an opening, and only the part close to the side extends so as to be fixed to the mobile phone
  • the part of the bottom surface of the protective cover that extends from the side can cover the area that needs to be protected such as the camera, so that the camera protruding from the back of the phone will not protrude from the protective cover

  • the protective layer is usually tempered glass (such as gorilla, sapphire glass, etc.). After the emergence of the special-shaped screen led by iPhone X, the risk of mobile phone being broken due to falling or other external forces is increasing. In most cases, only the tempered glass of the protective layer of the LCD screen is damaged, and it is usually caused by impacts on the four corners of the screen. Then, as long as the four corners of the display are protected, the risk of broken screen can be greatly reduced.
  • US invention patents US 8,909,309 and US 9,247,795 respectively protect the corners of the adjacent sides of the device and the back panel of the mobile phone.
  • the back panel is the most resistant part of the portable device.

  • the phone shell can also absorb impact energy.
  • the common mobile phone cases in the market can be divided into bottom and side.
  • the bottom and sides are usually curved.
  • the former can be extended outwards at 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 the mobile phone, and “outward” is the direction facing the user), so that when the mobile phone falls or is impacted by other external forces , The four corners of the display screen will not be impacted, unless the extension part has a great deformation, so that the four corners of the display screen are also impacted by the ground/impact object.
  • 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.
  • these extensions can include one or more layers of airbags to increase their cushioning capacity.
  • the airbags can even be designed to have a fragile structure at a certain location. After an impact, gas can leak through this structure, further increasing the redundancy of absorbing impact energy. degree. The faster the exhaust speed, the stronger the buffer capacity.
  • the metal back cover Because the metal has sufficient ductility, when the back cover of the mobile phone is hit due to a fall, it will cause the metal back cover to dent, but it will not affect the internal structure of the mobile phone.
  • the back cover made of glass there is a risk of the back cover breaking. However, a broken glass back cover will not affect the internal structure of the phone. If the internal structure of the mobile phone is damaged, the protective sleeve cannot protect the mobile phone either.
  • the first embodiment of the present invention ( Figure 1/2 and Figure 5/6) can also be used on the back side to extend the protective glass rear shell horizontally through the four corners of the back side. The second option ( Figure 3/4) will affect the feel.
