Hinge assembly for foldable electronic device
First Claim
1. A hinge assembly for joining a body and a cover of a foldable electronic device, the hinge assembly comprising:
- an outer housing being a hollow cylinder for being coupled to the cover;
an inner housing within said outer housing, said inner housing having two ends, one end being open, the other end being a head with a setting hole, wherein said head is coupled to the body;
a can received in the inner housing, said can having two ends, one end being a protrusion defining a hole, the other end being a cylindrical acceptor;
a torsion-bar spring received in said inner housing, said torsion-bar spring having opposite first and second ends, the second end of said torsion-bar spring being secured with said can;
a slider comprising a first end having a block and a second end being a cylinder defining a cavity, said block being engaged in the hole of said can, wherein when said slider axially moves, said block is freed from the hole of said can and is able to rotate relative to said can;
a securing portion coupled in said cavity of said slider and secured with said outer housing and the first end of said torsion-bar spring; and
a key received in said setting hole of said inner housing to press said block of said slider.

Abstract
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 (132b) 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.

18. A hinge assembly for joining a body and a cover of a foldable electronic device, the hinge assembly comprising:
-
an outer housing being a hollow cylinder for being coupled to the cover; an inner housing within said outer housing, said inner housing having two ends, one end being open, the other end being a head with a setting hole, wherein said head is coupled to the body; a can received in the inner housing, said can having two ends, one end being a protrusion defining a hole, the other end being a cylindrical acceptor; a pressure spring disposed around said protrusion of said can; a torsion-bar spring received in said inner housing, said torsion-bar spring having opposite first and second ends, the second end of said torsion-bar spring being secured with said can; a slider comprising a first end having a block and a second end being a cylinder defining a cavity, a securing portion coupled in said cavity of said slider and secured with said outer housing and the first end of said torsion-bar spring; and a key received in said setting hole of said inner housing to press said block of said slider.

19. A hinge assembly for joining a body and a cover of a foldable electronic device, the hinge assembly comprising:
-
a can being only linearly moveble; a fastener being only rotatably moveable; a torsion plus compression spring having two opposite ends respectively restricted at the can and the fastener; and a slider abutting against the spring;
whereinwhen said slider is axially moved to a first axial position to compress the spring, one end of said slider is released from the can so as to allow the fastener with the associated said slider to be rotated by means of a biasing force generated by the spring; and
when said slider is axially moved to a second axial position and engaged with the can, the spring is relaxed axially but tensioned rotatably. - View Dependent Claims (20)
