发明名称 Hinge assembly for foldable electronic device
摘要 A hinge assembly ( 10 ) for joining a body and a cover of a mobile phone includes an inner housing ( 100 ), a key ( 110 ), a pressure spring ( 120 ), a can ( 130 ), a slider ( 140 ), a damper ( 150 ), an outer housing ( 160 ), a fastener ( 170 ), and a torsion-bar spring ( 190 ). The can includes an acceptor ( 132 ) defining an axial slot ( 132 b) in a peripheral wall thereof, and a protrusion ( 131 ) having a stepped hole. The slider has an adjoining block ( 141 ) received in the stepped hole. One end of the torsion-bar spring is secured onto the fastener, and the other end of the torsion-bar spring is received in the slot. A user presses the key to slidably remove the slider from the stepped hole of the can, whereupon the torsion-bar spring can rotationally drive the slider and the fastener, with the outer housing turning in unison therewith. Thus the cover is opened.
