Abstract
The present application relates to the field of electronic device fittings, and aims to solve the problem of it not being possible for known hinges to have a simple structure and also better meet rotational damping requirements. Provided are a hinge assembly, a support apparatus, an electronic device assembly and a foldable device. The hinge assembly comprises a rotary shaft, a first leaf and a second leaf. The first leaf comprises a first leaf plate and first sleeves. The second leaf comprises a second leaf plate and a second sleeve, wherein slits in the second leaf plate divide the second sleeve into a main sleeve and side sleeves. The first sleeves are provided with engagement recesses in a protruding manner, and the side sleeves are provided with engagement protrusions. In a first state, the engagement protrusions engage into the engagement recesses; and in a second state, the engagement protrusions and the engagement recesses are staggered in the circumferential direction, and the engagement protrusions of the side sleeves elastically abut against the first sleeves. The beneficial effect of the present application lies in: being capable of providing a better damping effect and a flattened state maintaining capacity.
