Abstract: A rotating module includes a fixing member, a rotating member rotatably mounted on the fixing member, a swinging arm and a first elastic member. The swinging arm includes a first end and a second end. The first end is hinged to the rotating member, the second end is slidably and rotatably mounted to the fixing member. The first elastic member is fastened between the fixing member and the second end, the rotating member is rotated relative to the fixing member to drive the second end to slide on the fixing member to compress or release the first elastic member.

Abstract: An electronic device includes a housing and a nut. The housing defines a fixing hole. The nut is located in the fixing hole. The nut is shaped to fit in the housing and leave a receiving space. Glue is used in the receiving space for fixing the nut to the housing.

Abstract: An exemplary battery cover latching mechanism for latching a battery cover to a rear cover, includes a rod, a suction cup, an elastic element and a sliding key. The rod has a first end and a second end, is hinged to the rear cover, and includes a first positioning slot and a second positioning slot. The suction cup is mounted at the first end of the rod. The elastic element is mounted on the second end of the rod and resisting the rear cover. The sliding key is slidably mounted to the rear cover. When the sliding key latches with the first positioning slot, the suction cup sucks the battery cover to the rear cover; when the sliding key slides out of the first positioning slot to the second positioning slot, the rod rotates relative to the rear cover to release the battery cover.

Abstract: A portable electronic device includes a base, a cover, and a connecting module. The connecting module includes two connecting plates and at least one hinge. At least one of the connecting plates is rotatably connected to the base or cover by the at least one hinge, and the cover rides the base when rotated and slid thereon.
