Claim:
A slide cover lifting structure used in an electronic device comprising a cover panel and a base member, the slide cover lifting structure comprising: two hinges respectively fixedly mounted in two opposite sidewalls of said base member, each said hinge comprising a bracket, a non-circular pivot axle and a torque providing device; two sliding rail holders respectively connected to the non-circular pivot axles of said two hinges and rotatable with the associating non-circular pivot axles relative to said base member, each said sliding rail holder comprising a connection block connected to the non-circular pivot axle of the associating hinge; two bearing members respectively affixed to said sliding rail holders, each said bearing member having two grooves disposed at two opposite lateral sides thereof; two plastic slide guides respectively formed of a pair of channel bars and respectively fixedly mounted in the grooves of said bearing members, each said channel bar defining a sliding groove; two sliding rails bilaterally fixedly mounted on a bottom surface of said cover panel in a parallel manner, each said sliding rail comprising a flat, elongated base panel affixed to said cover panel, an angled rail extending along each of two opposite lateral side of said flat, elongated base panel and respectively slidably coupled to the sliding grooves of the channel bars of said plastic slide guides; a transmission shaft having two distal ends thereof respectively inserted through the brackets of said hinges and affixed to said base member; two gear sets partially pivotally mounted on said sliding rail holders and partially pivotally mounted on the brackets of said hinges, each said gear set comprising a first gear mounted on one of the two distal ends of said transmission shaft and a last gear partially and upwardly protruding over the associating sliding rail holder and the associating bearing member; and two gear racks respectively affixed to the flat, elongated base panels of said sliding rails at a bottom side thereof and respectively meshed with the last gears of said gear sets; wherein said two sliding rails are moved with said cover panel in the sliding grooves of said plastic slide guides relative to said base member when said cover panel receives a horizontal push force, and the same time, said gear racks are forced to rotate the last gears of said gear sets, enabling the horizontal push force to be evenly transferred through said transmission shaft to the two opposite lateral sides of said base member; when said cover panel is tuned about the pivot axles of said hinges relative to said base member, the last gears of said gear sets are kept in positive engagement with said gear racks.
