20100064478HINGE ASSEMBLY FOR PORTABLE ELECTRONIC DEVICES - A hinge assembly (03-18-2010
20100071158HINGE ASSEMBLY FOR FOLDABLE ELECTRONIC DEVICES - A hinge assembly includes a shaft, a follower and an elastic element. The shaft forms a projection. The follower defines a through hole and forming an inner peripheral wall surrounding the through hole. A threaded portion is formed on the inner peripheral wall, and the projection engages with the threaded portion of the follower. The elastic element provides an axial force to push the follower rotatable about and simultaneously longitudinally movable along the shaft.03-25-2010
20100107366HINGE ASSEMBLY FOR FOLDABLE ELECTRONIC DEVICE - A hinge assembly includes a shaft, a cam, a follower, and an resilient member. The cam, the follower, and the resilient member are mounted with the shaft in turn. One end of the cam has a first outer cam portion and a first inner cam portion. One end of the follower has a second outer cam portion and a second inner cam portion respectively engaging with the first outer and inner cam portions. The resilient member is contained in such a manner that the cam portions of the follower resist the cam portions of the cam due to the decompression of the resilient member, and when the follower is manually rotated relative to the cam about a small original angle, the follower is automatically rotated relative to the cam due to the decompression of the resilient member.05-06-2010
20100162526HINGE ASSEMBLY FOR FOLDABLE ELECTRONIC DEVICE - A hinge assembly includes a shaft, a main body drive member, a follower, and a resilient member. The main body drive member, the follower, and the resilient member are mounted with the shaft in turn. One end of the main body drive member has a cam. One end of the follower has a cam engaging with the cam of the main body drive member. The resilient member causes the cam of the follower to resist the cam of the main body drive member due to the decompression of the resilient member, and when the follower is manually rotated relative to the main body drive member about an angle, the follower is automatically rotated relative to the main body drive member due to the decompression of the resilient member.07-01-2010
20100180401HINGE HOUSING FOR HINGE ASSEMBLY - A hinge assembly includes a pivot shaft, a rotary element, an elastic element, a cam and a hinge housing. The rotary element is slidable and rotatable relative to the pivot shaft. The elastic element is placed around the pivot shaft. The cam is engaged with the rotary element by the elastic element. The cam is fixed with the shaft. The hinge housing has an open end and a partially-closed end. The receiving portion is formed adjacent to the open end. The receiving portion is radially expandable. The pivot shaft passes through the hinge housing from the partially-closed end. The elastic element is received in the hinge housing, and is placed around the shaft. The cam is received in the receiving portion.07-22-2010
20100205778WASHER FOR HINGE ASSEMBLY - A washer is for a hinge assembly. The hinge assembly includes a shaft. The washer is placed around the shaft. The engagement between the washer and the shaft is a clearance fit. By the clearance engagement between the washer and the main shaft, the mechanism efficiency is greatly improved.08-19-2010
20110067203HINGE ASSEMBLY FOR FOLDABLE ELECTRONIC DEVICE - A hinge assembly includes a shaft, a cam, a follower, and an resilient member. The follower is mounted on the shaft. One end of the follower has a first cam surface. The first cam surface defines a groove. The cam is mounted on the shaft and adjacent to the follower. The cam has a second cam surface, and the second cam surface engages with the first cam surface. The second cam surface forms a protrusion, and the protrusion is received in the groove. The resilient member is placed around the shaft forcing the first cam surface to engage with the second cam surface.03-24-2011
20110075333SLIDING AND TILTING MECHANISM AND PORTABLE ELECTRONIC DEVICE USING THE SAME - A portable electronic device is disclosed including a first part, a second part, and a sliding and tilting mechanism. The sliding and tilting mechanism includes a lower board fixed to the second part, an upper board fixed to the first part, an intermediate board positioned between the lower board and the upper board. The sliding and tilting mechanism further includes two elastic assemblies, a swinging member, and a cam member, all of which engage with each other to tilt the intermediate board and the upper board relative to the lower board after the upper board slides over a predetermined distance along the intermediate board.03-31-2011
20110096475SLIDE MECHANISM FOR SLIDE-TYPE PORTABLE ELECTRONIC DEVICE - A slide mechanism includes a first plate defining two first guiding slots, a second plate defining two second guiding slots, and two connecting bodies. Each connecting body passes through the first guiding slot and the corresponding second guiding slot to connect the first plate and the second plate, and the connecting body is slidable relative to the first guiding slot and the second guiding slot. The invention also discloses a portable electronic device applying the slide mechanism.04-28-2011
20110096479SLIDING AND TILTING MECHANISM AND PORTABLE ELECTRONIC DEVICE USING THE SAME - A portable electronic device is disclosed including a first part, a second part, and a sliding and tilting mechanism. The sliding and tilting mechanism includes a lower board fixed to the second part, an upper board fixed to the first part, an intermediate board positioned between the lower board and the upper board. The sliding and tilting mechanism further includes two elastic assemblies and a tilting assembly, and tilts the intermediate board and the upper board relative to the lower board after the upper board slides over a predetermined distance along the intermediate board.04-28-2011
20110109212SLIDING MECHANISM AND ELECTRONIC DEVICE HAVING THE SAME - A sliding mechanism comprises a sliding plate, a main plate, a sliding enabling member, a biasing member and a stopping member. The sliding plate has sidewalls and the main plate has peripheral walls corresponding to the sidewalls, respectively. The slide enabling member is coupling the sidewalls to the peripheral walls such that the sliding plate is slid relative to the main plate between closed and open position. The biasing member provides a force for biasing the sliding plate to slide relative to the main body. The stopping member is coupled between the sliding plate and the main plate. When the sliding plate is slid from the open position to the closed position, the stopping member provides a mechanism for the sliding plate to steadily slide relative to the main plate and to firmly stop in the closed position.05-12-2011
20110157787HINGE ASSEMBLY FOR FOLDABLE ELECTRONIC DEVICE - A hinge assembly includes a shaft, a seat made of plastic, a follower, a cam, a latching member and a resilient member. The follower includes a cam surface. The seat is fixed to the follower, and the seat and the follower are placed around the shaft. The cam has a latching cam surface, the cam surface being engaged with the cam latching surface. The latching member is fixed to the cam, and the cam and the latching member are placed around the shaft. The resilient member is placed around the shaft and provides an elastic force to make the cam surface abut against the latching cam surface.06-30-2011
20110164358SUPPORT MECHANISM FOR PORTABLE ELECTRONIC DEVICE - An exemplary support mechanism for a portable electronic device includes a seat, a button, a support member, and a hinge assembly. The seat defines a cavity. The button is received in the cavity. The support member includes a knuckle portion. The knuckle portion is received in the cavity. The button abuts against the support member. The hinge assembly connects the knuckle portion to the seat. When the button is pressed to force the hinge assembly to unlock, the hinge assembly drives the support member to rotate.07-07-2011
