Abstract
A cover hinge structure having self-protection function, which consists of a cylindrical hinge pin and a hook. The hinge pin and the hook are integrated with a body and a cover, respectively. An engaging groove with an opening narrower than the hinge pin forms at the engaging end of the hook. When the cover is lifted to the limit, the action force acted by the pin on the hook from directs toward the opening of the engaging groove and the direction of the action force is the same as the opening direction of the engaging groove. Thus, the pin detaches from the hook automatically before damage to the hinge structure occurs if great force is applied.
