7results about How to "Add support function" patented technology

This utility model discloses a tablet computer protective case, including a housing for accommodating the tablet computer and a support frame for supporting the housing. The support frame includes a first support frame and a second support frame. The first support frame is hinged to the back of the housing in a flip-out manner, and the second support frame is hinged to the middle of the first support frame in a flip-out manner relative to the first support frame. A clearance space is provided on the first support frame for the second support frame to flip back to its original position, and the second support frame, after flipping back to its original position, is located within the clearance space. Therefore, by utilizing the multiple flip angles and combinations of the first and second support frames, multiple angle supports for the housing can be achieved, enabling the protective case to provide writing and drawing support and height support for the tablet computer, meeting various user needs and improving the user experience.
