Abstract:
A hinge mechanism includes at least two shafts arranged in a row, a linkage mechanism and two connecting parts. The two connecting parts are fixedly connected to two shafts on the outermost sides, respectively. Two adjacent shafts are connected by the linkage mechanism. The linkage mechanism includes a first linkage and a second linkage. One of the two adjacent shafts is hinged to a first end of the first linkage, the other one is hinged to a first end of the second linkage, and a second end of the first linkage is hinged to a second end of the second linkage. When hinge points where the first linkage and the second linkage are respectively hinged to the two adjacent shafts and a hinge point between the first linkage and the second linkage are in a same straight line, there is a gap between the two adjacent shafts.
