Abstract: A battery cover mechanism used in a portable electronic device includes a housing having an assembly groove and at least one holding aperture, a cover forming at least one lock and a rib at two ends thereof respectively, a latch member, and an elastic unit. The lock latches the holding aperture correspondingly, the latch member is slidably assembled in the assembly groove, the elastic unit is assembled in the assembly groove and resists the latch member, and the latch member latches the rib to latch the cover with the housing.

Abstract: A battery cover mechanism for a portable electronic device includes a housing, a door, two first elastic members and a holding unit, the housing defines a cutout, the door slidably engage with the cutout, the cutout is closed by the door with the elastic resisting the door, the door can be opened by external force and not be removed from the housing, thus, a battery can be assembled in the housing.

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.

Abstract: A battery cover assembly comprises a housing, a battery cover, a magnetic element and iron core. The battery cover has a first surface facing the housing. The battery cover has a plurality of latching portions protruding from the first surface and located adjacent to one side thereof. The magnetic element is mounted to the first surface of the battery cover and located adjacent to anther side thereof. The iron core is mounted to the housing corresponding to the magnetic element. The magnetic element is magnetically attracted with the contacting portion and the latching portions are correspondingly latched in the latching slots, which corporately latches the battery cover to the housing.

Abstract: A hinge assembly (100) includes a main shaft (50), a fixing seat (80), a follower (44), a cam (42) and a first elastic element (30). The fixing seat is fixed with the main shaft. The follower is placed around the shaft, and the fixing seat selectively locks with the follower. The cam is placed around the shaft, and engages with the follower. The first elastic element provides an elastic force to make the cam and the follower resist each other and provides a torsional force to make the cam and the follower rotate together.

Abstract: An insert molding article (20) includes a plastic element (24) and an inserting element (22). The inserting element includes a main portion (222) and an inserting portion (224) formed on and extending from the main portion. The inserting portion is enclosed, encapsulated, and secured in the plastic element. By being molded in such a manner, the plastic element frictionally engages at least two sides of the inserting portion, thereby resulting in a mechanically stable connection between the plastic element and the inserting portion.
