HINGE ASSEMBLY FOR PORTABLE ELECTRONIC DEVICES
First Claim
1. A hinge assembly, comprising:
- a connecting member comprising a first sleeve, a second sleeve and a connecting sleeve connected between the first sleeve and the second sleeve, the first sleeve and the second sleeve respectively having a partition board formed therein, each partition board having a plurality of protrusions extending therefrom with a plurality of latching grooves formed between the protrusions;
two cams, each cam having at least one latching block and defining an axial hole, the at least one latching block engaging in a corresponding latching groove;
two shafts, each shaft having a shaft portion, the shaft portion being structured and arranged for passing through the axial hole of each cam for rotating together with the cam; and
two elastic elements, each elastic element providing an elastic force for each cam so as to hold each cam against a corresponding partition board.

Abstract
A hinge assembly (200) includes a connecting member (10), two cams (30), two shafts (20), two elastic elements (40) and two barrels (50). The connecting member includes a first sleeve (12), a second sleeve (14) and a connecting sleeve (16) connected between. The first sleeve and the second sleeve each have respective partition boards (104, 144) formed therein. Each partition board includes a plurality of protrusions extending therefrom with a plurality of latching grooves formed between the protrusions. Each cam includes at least one latching block (32) and defines an axial hole (36). Each shaft has a shaft portion (24), and the shaft portion is configured for passing through the axial hole of each cam. Each elastic element provides an elastic force for each cam so as to hold the cam against the protrusions.

10. A hinge assembly of a foldable electronic device comprising a housing and a cover, the hinge assembly comprising:
-
a connecting member including a first connecting portion configured so as to be rotatably received in the housing, a second connecting portion configured so as to be rotatably received in the cover, and a third connecting portion connecting the first connecting portion with the second connecting portion in a manner such that the first connecting portion and the second connecting portion are non-removable relative to each other, the first connecting portion and the second connecting portion respectively defining a first rotation axis and a second rotation axis that are parallel to each other;
a first rotation limiting unit configured so as to be engaged between the first connecting portion and the housing in a manner so as to limit the housing to rotate within a first predetermined angle relative to the first rotating axis; and
a second rotation limiting unit configured so as to be engaged between the second connecting portion and the cover in a manner so as to limit the cover to rotate within a second predetermined angle relative to the second rotating axis. - View Dependent Claims (11, 12, 13, 14)
