Abstract: A replaceable panel device (1) includes a panel (20) with a mounting portion (24), a locking subassembly (30), and a top cover (40) with a block (45). The mounting portion has at least one slideway (241), a recess (242), and two locating grooves (243). The locking subassembly is accommodated in the mounting portion of the panel. The locking subassembly has a button (31), an elastic rod (32), and a slider (33). The button has at least one rail (312), a hole (313) defined at top of the rail. The slider has at least one slot (331) and a rabbet (332). The slider is received in the recess. The rail is received through the slideway and the slot. The elastic rod is received through the hole. Ends of the elastic rod are located in the locating grooves. The rabbet engagingly receives the block of the top cover.

Abstract: An enclosure of a mobile phone with changeable panel includes a front cover (1), a panel (2), a rotatable holder (3), and a spring (4). The front cover defines a through hole (16) and latch slots (171, 172). The panel has projections (241, 242) at an edge thereof, and the projections can be engaged in the latch slots of the front cover. The panel further has a hole (25) corresponding to the through hole of the front cover. The holder has a latch portion (33), and the spring is engaged around the holder. The holder with the spring is received in the hole of the panel, and the holder is further received in the through hole of the front cover. The holder is rotated and the spring is compressed, thereby securely holding the panel on the front cover.

Abstract: A connecting mechanism for a battery case and a main body of a portable electronic device includes a main body (10), a connecting member (20), a cover (30), and a shaft (40). The main body has a receptacle (162), and a recessed portion (192) for receiving the battery case. The connecting member has a body (22) and one or more mounting portions (24). The cover defines a sliding space. The shaft extends through the mounting portions and is received in the receptacle. Thus the connecting member is rotatable relative to the main body about the shaft. The connecting member is received in the sliding space and can slide along the sliding space relative to the cover. Thus the cover is both rotatable and slidable relative to the main body, and need not be detached from the main body.

Abstract: A hinge assembly includes a body drive member (1), a cover drive member (2), and a locating member (3). The body drive member has an outer screw thread (16) on an outer periphery thereof. The cover drive member has a central cavity (212, 224), and a projection (223) and an inner screw thread (216) formed in the cavity. The locating member has a projection (31) formed on an outer periphery thereof, and a central hole (33). The body drive member extends through the cavity and the hole, thereby integrating the hinge assembly into a complete unit, with the thread of the body drive member engaging with the thread of the cover drive member, and the projection of the cover drive member movably engaging with the projection of the locating member. The hinge assembly exerts reduced force on a foldable electronic device when the foldable electronic device is opened or closed.

Abstract: A portable electronic device includes a removable panel (10) defining a first latching hole (122) therein, a knob (30), and a base cover (40). The knob includes an operating portion (31) and a shaft portion (32). A catch (321) extends from the shaft portion. The shaft portion is rotatably received in the first latching hole, with the operation portion being above an upper surface of the removable panel, and the catch being below a lower surface of the removable panel. A second latching hole (450) and a latching hatch (454) are defined in the base cover. The removable panel is attached to the base cover by way of the shaft portion of the knob being inserted into the second latching hole with the catch being received through the latching hatch, and the operating portion of the knob then being rotated so that the catch is engaged below the base cover.

Abstract: A hinge assembly includes a body drive member (1) having an outer screw thread (16), a cover drive member (2) having a projection (26) on an outer periphery, and a locating member (3). The cover drive member defines a central hole (23) and an inner screw thread (25) therein. The locating member has a base board (31), and a hatch (32) defined therein. Two arms (33) extend from opposite edges of the base board, and a bent portion (34) is formed at a distal end of each arm. The body drive member extends through the hatch and the hole, thereby integrating the hinge assembly into a complete unit, with the outer screw threadingly engaging with the inner screw thread, and the projection abutting the bent portion. The hinge assembly exerts reduced force on a foldable electronic device when the foldable electronic device is opened or closed.

Abstract: A cover assembly (1) of a mobile phone includes a front cover (2) and a back cover (3). The front cover defines a front microphone cavity (4) at an end thereof with at least one opening formed in a wall of said front microphone cavity. The back cover defines a back microphone cavity (5) at an end thereof, corresponding in position to that of the front microphone cavity in the front cover. At least one opening is formed in a wall of said back microphone cavity. Said front and back covers are assembled together to form the cover assembly, resulting in a combination of said front and back cavities to create a combined microphone cavity (90) for receiving a microphone (70) therein, the combined cavity having at least one aperture (46) at its lower end, thereby improving voice quality and structural integrity of the mobile phone.
