Abstract

A fixing structure for fixing a casing and a base frame of an electronic device together includes: a melt hole disposed in the base frame and a melt post formed on the casing, wherein the melt hole is provided with an opening having its diameter being gradually enlarged from inside outward, so that when combining the casing with the base frame, the melt post passes through the melt hole and is exposed by the opening. Through the design of the opening, the fixing effect upon melting can be strengthened without occupying a lot of space around the melt hole.

Claims

1. A fixing structure for fixing a casing and a base frame of an electronic device together, comprising:

a melt hole formed on the base frame and provided with an opening having its diameter being gradually enlarged from inside outward; and

a melt post disposed on the casing, wherein when combining the casing with the base frame, the melt post passes through the melt hole and is exposed by the opening of the melt hole, and a portion of the melt post is melted to fill the opening.

2. The fixing structure of claim 1, wherein the opening is provided with a single level of difference in diameter.

3. The fixing structure of claim 1, wherein the opening is provided with a plurality of levels of difference in diameter.

4. The fixing structure of claim 2, wherein a longitudinally cross-sectional shape of the opening is at least one of a rectangle and a trapezoid.

5. The fixing structure of claim 3, wherein a longitudinally cross-sectional shape of the opening is at least one of a rectangle and a trapezoid.

6. The fixing structure of claim 2, wherein a longitudinally cross-sectional shape of the opening is a quadrangle with two sides thereof in an arc shape.

7. The fixing structure of claim 3, wherein a longitudinally cross-sectional shape of the opening is a quadrangle with two sides thereof in an arc shape.

8. The fixing structure of claim 1, wherein the melt hole has a shape of one selected from the group consisting of a cylinder shape and a square column shape.

9. The fixing structure of claim 1, wherein the melt post has a shape of one selected from the group consisting of a cylinder shape and a square column shape.

10. The fixing structure of claim 1, wherein the casing is made of plastic material.

11. The fixing structure of claim 1, wherein the melt post is integrally formed with the casing.

12. The fixing structure of claim 1, wherein the base frame is made of metal.
