Abstract: The chip card holder includes a body member, a card receiving space formed on the body member and a releasing piece. The card receiving space has an opening to insert a chip card along a direction perpendicular to the longitudinal direction of the card receiving space. The releasing piece is slidably mounted on the body member along the longitudinal direction and is configured for either exposing the opening to insert the chip card or locking the chip card in the card receiving space.

Abstract: A hinge assembly (100) for a foldable electronic device (200) includes a shaft (40), a first follower (33) attached on one end of the shaft, a first cam (34) rotatably attached on the shaft, a resilient member (50) having one end abutting the first cam, a second cam (63) rotatably attached on the shaft and abutting the other end of the resilient member, a second follower (62) attached on the shaft, and a button (70) attached on the other end of the shaft and abutting the second follower. The first follower is rotating with the shaft and has a first follower surface (332). The first cam has a first cam surface (342) engaging with the first follower surface. The second cam has a second cam surface (632). The second follower has a second follower surface (624) engaging with the second cam surface.
