Claim:
A double sliding stability space-saving slide cover lifting structure used in an electronic device comprising a cover panel and a base member, the double sliding stability space-saving slide cover lifting structure comprising: two hinges respectively fixedly mounted in a respective recessed portion on a middle part of a top wall of said base member adjacent to two opposite lateral sides of said base member, each said hinge comprising a non-circular pivot shaft and a torque providing device; two sliding rail holders respectively connected to the non-circular pivot shafts of said two hinges and rotatable with the associating non-circular pivot shafts relative to said base member, each said sliding rail holder comprising a connection block connected to the non-circular pivot shaft of the associating hinge; two bearing members prepared by a high load strength material and 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; an axle having two distal ends thereof respectively pivotally coupled to said sliding rail holders; two gears respectively mounted on said axle near said sliding rail holders, each said gear having the gear teeth thereof partially and upwardly inserted through said sliding rail holder and said bearing members; and two gear racks respectively affixed to the flat, elongated base panels of said sliding rails and respectively meshed with said gears; 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 said gear racks are simultaneously moved with said cover panel to rotate said gears, enabling the horizontal push force to be transferred through said gears to two opposite lateral sides of said base member to prohibit said cover panel from biasing during sliding movement; said gears are kept meshed with said gear racks constantly for enabling said cover panel to be turned about the non-circular pivot shafts of said hinges from a horizontal position to a tilted position relative to said base member.
