Description

Protective cover device

technical field

The invention relates to a protective cover for a device, in particular to a protective cover for a portable electronic device. the

Background technique

Tablet computers are popular in the consumer market due to their portability. When in use, the user usually holds the tablet computer with one hand and touches the screen with the other hand. If both hands need to be operated at the same time, such as touching the screen with both hands at the same time, using an external keyboard to input, etc., the tablet computer needs to be placed on the desktop or other on the stand. At present, there are foldable protective covers on the market. When the protective cover is flattened, it can just cover the screen; when it is folded into a support frame, it can support the tablet computer at an angle to match the user's different postures. This type of protective cover itself usually only has the function of screen protection and support. At present, there is a type of external keyboard on the market, which can provide a tablet computer support function, and the user can use both hands to operate the keyboard facing the tilted tablet computer. This type of external keyboard usually does not have the function of a protective cover, and when stored, it needs to occupy an area larger than that of a tablet computer, which is not conducive to storing the two together. Although some external keyboards have the functions of support and protection, the protection function is also limited to the protection of the screen. The above-mentioned protective cover with support function or the external keyboard with both support and protection functions can only protect the screen part of the tablet computer at most, but cannot protect the entire tablet computer, so in fact, the user will still be on the outside of the two. Put the protective cover on the case to provide the overall protection of the tablet. Therefore, there is currently a need for a device that can have both a support function and a complete protection function. the
