Hinge

A hinge adapted to interconnect first and second objects comprising:

• a leaf unit including first and second leaves that are rotatable relative to each other, said first leaf having at least one first barrel, said second leaf having at least one second barrel that is spaced apart from said first barrel along an axis;
• first and second action units being inserted into said first barrel and said second barrel respectively in two opposite directions along the axis, and being co-rotatable with said first leaf;
• and
• an axle unit including a fixing member that is mounted in said second barrel of said second leaf, that has a through hole, and that is co-rotatable with said second leaf, and first and second axle constituents that are respectively connected to said first and second action units and that are co-rotatably mounted to said fixing member, each of said first and second axle constituents and the respective one of said first and second action units being rotated relative to each other upon relative rotation between said first and second leaves;
• wherein said first action unit includes a tubular member that is inserted into said first and second barrels and that is co-rotatable with said first leaf, a hydraulic module that is disposed in said tubular member, a proximal acting member that is co-rotatably mounted in said tubular member, and a cap member that is mounted to an end of said tubular member, said hydraulic module including a hydraulic cylinder, an abutment pin that is disposed between said hydraulic cylinder and said first axle constituent, and a resilient member that is disposed between said hydraulic cylinder and said first axle constituent, said proximal acting member having a proximal inclined surface that faces away from said fixing member, and a through hole that permits said first axle constituent to extend therethrough, said first axle constituent having an abutment surface that abuts against said abutment pin and said resilient member, and a proximal follower surface that is opposite to said abutment surface and that is in contact with said proximal inclined surface of said proximal acting member, said first axle constituent moving along the axis upon the relative rotation between said first and second leaves;
• and
• wherein said first action unit further includes a distal acting member that is co-rotatably mounted in said tubular member, said first axle constituent further having a distal follower surface that is opposite to said proximal follower surface, said distal acting member being located between said hydraulic cylinder and said first axle constituent, and having a distal inclined surface that is in contact with said distal follower surface of said first axle constituent.
