Corner protection device and computer bag

Abstract

A corner protection device includes two corner pads disposed opposite to each other. The corner pad includes a bottom plate and a side wall which are connected, the side wall includes a first wall, a transition wall and a second wall which are connected in sequence, and an inner wall surface of the first wall is perpendicular to an inner wall surface of the second wall; and the bottom plates in the two corner pads are disposed away from each other, and the bottom plates protrude inwardly relative to the inner wall surfaces of the side walls. Corners of a notebook computer can be protected in an all-directional manner at an angle of 360° without a dead angle, thereby greatly reducing the risk of accidental damage to the corners of the notebook computer loaded in the computer bag.
