RELATED APPLICATIONS The present application is based on, and claims priority from, Taiwan Application Serial Number 95219653, filed on Nov. 7, 2006, the disclosure of which is hereby incorporated by reference herein in its entirety.
The present invention relates to a hinge structure.
An electronic device is equipped with a hinge to interconnect one part and the other part thereof such that one part can be rotated relative to the other part thereof. Nowadays, the hinge structure needs more functions, i.e. rotation positioning and rotation range restriction, besides its rotatable connection function for user's convenience. Therefore, an improved hinge structure is necessary.
SUMMARY A hinge module includes a hollow cylinder, a movable part and a cover. The hollow cylinder has a positioning slot in an inner wall thereof. The movable part has a positioning convex portion and a plurality of engraved portions, wherein the positioning convex portion engages with the positioning slot such that the movable part slides within the hollow cylinder. The engraved portions are radially arranged on the movable part. A resilient part is disposed within the hollow cylinder. The cover is fixed to the hollow cylinder to secure the movable part and the resilient part within the hollow cylinder. The resilient part is disposed between the cover and the movable part so as to provide the movable part a resilient recovery force. The engraved portions of the movable part are for engaging a rotatable member.
FIG. 1 illustrates an expansion device according to one embodiment of this invention;
FIG. 2 illustrates an exploded view of an expansion device according to one embodiment of this invention;
FIG. 3 illustrates an exploded view of a hinge body of the expansion device according to one embodiment of this invention; and
FIG. 4 illustrates two sides of a hollow cylinder according to one embodiment of this invention.
FIG. 1 illustrates an expansion device according to one embodiment of this invention. The expansion device 100 includes a stationary member 102 and a rotatable member 104. A hinge module 106 interconnects the stationary member 102 and the rotatable member 104. Thus, the rotatable member 104 can rotate relative to, along the rotation direction 132 for example, the stationary member 102 such that a connection interface 130 can be swiveled to a desired position where a connection connector is readily plugged and removed for users. The connection interface 130 includes several types of input/output ports, such as IEEE 1394, USB (Universal Serial Bus), D-sub, DVI or Audio ports to communicate computer accessories.
FIG. 2 illustrates an exploded view of an expansion device according to one embodiment of this invention. The hinge module 106 includes a screw 106 a, a washer 106 b and a hinge body 107. Two support frames of the stationary member 102 both include a circular concave section 108 a and 108 b. The circular concave section 108 a is to accommodate the screw 106 a and the washer 106 b. The circular concave section 108 b is to accommodate the hinge body 107. The circular concave section 108 b has a fastening portion 112 and the hinge body 107 has a corresponding fastening portion 109 a. When the concave fastening portion 112 engages with the convex fastening portion 109 a, the hinge body 107 is secured within the circular concave section 108 b. The hinge body 107 has several engraved portions 107 c to engage a bar 105 a of the rotatable member 104. When the rotatable member 104 rotates, the bar 105 a engages with one of the engraved portions 107 c, thereby temporarily positioning the rotatable member 104.
How the expansion device being assembled is described below. The hinge body 107 is firstly accommodated within the circular concave section 108 b. The rotatable member 104 is positioned between two support frames of the stationary member 102 with its bar 105 a engaging with the engraved portions 107 c of the hinge body 107. The washer 106 b is then accommodated within the circular concave section 108 a. The screw 106 a is finally led through the washer 106 b, the opening 110 of the circular concave sections 108 b/108 b and the hole 107 b of the hinge body 107, and secured into the screw hole 105 b of the rotatable member 104. The washer 106 b can be an anti-wear metal member to prevent the screw 106 a from scratching a surface of the stationary member 102.
FIG. 3 illustrates an exploded view of a hinge body of the expansion device according to one embodiment of this invention. FIG. 4 illustrates two opposite sides of the hollow cylinder 109 in FIG. 3. The hinge body 107 provides the rotatable member 104 a temporary positioning function. The hinge body 107 includes a hollow cylinder 109, a movable part 107 a, one (or more) resilient part 111 and a cover 113. The hollow cylinder 109 has positioning slots 109 c (in inner walls) and cutouts 109 d. The cutouts 109 d of the hollow cylinder 109 is to restrict a rotation range of the bar 105 a (of the rotatable member 104). Disk-shaped movable part 107 a has positioning convex portions 107 d, several engraved portions 107 c and a hole 107 b. The positioning convex portions 107 d of the movable part 107 a engages with the positioning slots 109 c of the hollow cylinder 109 such that the movable part 107 a slides within the hollow cylinder 109 along an axial direction (of the hollow cylinder 109). The engraved portions 107 c are radially arranged on a side of the movable part 107 a, i.e. the engraved portions 107 c radially extend from the hole 107 b to form a cross-shaped engraved portion. The cover 113 has a hole 113 a and mounting holes 113 b. When components of the hinge body 107 are assembled, the movable part 107 a and the resilient part 111 are sequentially disposed inside the hollow cylinder 109 and then the cover 113 is fixed to the hollow cylinder 109. The mounting holes 113 b of the cover 113 engages with mounting pins 109 b of the hollow cylinder 109, ends of the mounting holes 113 b are pressed such that the cover 113 is fixed to the hollow cylinder 109 to secure the movable part 107 a and the resilient part 111 within the hollow cylinder 109. The hole 107 b of the movable part 107 a, the hole 111 a of the resilient part 111 and the hole 113 a of the cover 130 are all aligned such that the screw 106 a can be led through for fastening. The resilient part 111 is disposed between the cover 113 and the movable part 107 a to provide the movable part 107 a a resilient recovery force along an axial direction (of the hollow cylinder 109) such that the bar 105 a of the rotatable member 104 engages with one of the engraved portions 107 c and a rotation positioning function is thus provided. The resilient part 111 can be a bent circular metal. One or more resilient parts 111 can be used to provide the movable part 107 a a resilient recovery force.
As illustrated in FIGS. 2-4, a hollow cylinder 109 has two openings at two opposite ends (referring especially to FIG. 4). The cover 113 is fixed to one of the two openings at two opposite ends. When the movable part 107 a is secured within the hollow cylinder 109, all the engraved portions 107 c are visible through the other of the two openings of the hollow cylinder 107 a (especially referring to FIG. 2).
Thus, the hinge module of the present invention can provide a target device a rotation positioning function and a restriction rotation range, and can be easily embedded inside a small volume space of the target device.
