Abstract

An electronic device includes at least one hinge assembly and two bodies. The hinge assembly includes a main body and two shafts. One end of each of the shafts is pivotally connected to the main body, another end of each of the shafts has an embedded portion, and the embedded portion has a roughened structure thereon. The two bodies correspond to the two shafts respectively, each of the bodies has at least one depression, and the embedded portion of each of the shafts is embedded in the depression of the corresponding body and contacts an inner wall of the depression through the roughened structure.

First claim

What is claimed is:

1. An electronic device, comprising:
at least one hinge assembly comprising a main body and two shafts, wherein one end of each of the shafts is pivotally connected to the main body, another end of each of the shafts comprises an embedded portion, and the embedded portion comprises a roughened structure thereon; and
two bodies corresponding to the two shafts respectively, wherein each of the bodies comprises at least one depression, and the embedded portion of each of the shafts is embedded in the at least one depression of the corresponding body and fixed on an inner wall of the at least one depression through the roughened structure, wherein an entire surface of the inner wall is a smooth surface surrounding the embedded portion.

2. The electronic device according to claim 1 , wherein each of the bodies comprises a housing, and the at least one depression is formed in the housing.

3. The electronic device according to claim 2 , wherein the housing comprises at least one protrusion, and the at least one depression is formed in the at least one protrusion.

4. The electronic device according to claim 3 , wherein each of the bodies further comprises a cover, wherein the cover is assembled to the housing, and opposite ends of the hinge assembly are respectively adjacent and connected to the protrusion and the cover.

5. The electronic device according to claim 1 , wherein the at least one depression is a non-circular hole, and the embedded portion comprises a non-circular contour corresponding to the non-circular hole.

6. The electronic device according to claim 1 , wherein the two shafts are respectively pivotally connected to the main body along two rotating axes parallel to each other, and the embedded portion is embedded in the at least one depression of the corresponding body along a direction parallel to each of the rotating axes.

7. The electronic device according to claim 1 , wherein the two shafts are respectively pivotally connected to the main body along two rotating axes parallel to each other, the embedded portion comprises an outer surface extending around the corresponding rotating axis, and the roughened structure is formed on at least part of the outer surface.

8. The electronic device according to claim 1 , wherein the at least one hinge assembly further comprises a linkage structure, and the linkage structure is connected between the two shafts.

9. The electronic device according to claim 8 , wherein the linkage structure is a gear set.

10. The electronic device according to claim 1 , further comprising a transmission wire and a wire sorting structure, wherein the transmission wire is connected between the two bodies, a section of the transmission wire passes through the wire sorting structure, and the wire sorting structure is disposed in the main body of the at least one hinge assembly.

11. The electronic device according to claim 10 , wherein the wire sorting structure is an elastic body.

12. The electronic device according to claim 10 , wherein the wire sorting structure comprises two assembly parts assembled with each other, and the section of the transmission wire is sandwiched between the two assembly parts.

13. The electronic device according to claim 1 , wherein the roughened structure is a texture structure.
