Hinge module for a foldable type device

A hinge module for a foldable type device, having one end surface simultaneously connected with a flexible display to have the flexible display relatively folded;

• the hinge module comprising a base and a first sliding mechanism, where one end of the base has a first pivoting hole and a second pivoting hole;
• the first sliding mechanism comprising:
• a first sliding cover, one end of which has a limiting space, and another end of which has a first limiting part;
• a supporting member, one end of which is elastically limited by way of sliding along a curved path in the limiting space, and another end of which has a supporting part;
• a four-linkage-mechanism, including a first linkage member, a second linkage member, and a third linkage member;
• where one end of the first linkage member is pivotally connected to the first pivoting hole by a first pivot, one end of the second linkage member is pivotally connected to the second pivoting hole by a second pivot, and another end of the second linkage member is pivotally connected to one end of the third linkage member by a third pivot, another end of the third linkage member is pivotally connected to another end of the first linkage member by a fourth pivot;
• and
• a swinging member, coupled to the third linkage member in a synchronous rotation, and one end of the swinging member is provided with a first lever, and the first lever passes through the first linkage member and is connected to the first limiting part of the first sliding cover;
• thereby when the first sliding mechanism and the base are rotated to move the four-linkage-mechanism, the first sliding cover is moved to offset the supporting part of the supporting member by an angle, so as to accommodate a curved part of the flexible display in a folded position.
