Abstract

A riveting structure and a riveting method are provided. The riveting structure includes a first metal element and a second metal element. The first metal element includes a first upper surface, a pressure-receiving portion and a recess portion. The recess portion is recessed from the first upper surface. The pressure-receiving portion is protruded from a surface of the recess portion. The second metal element includes a second lower surface and a protrusion portion and has a through hole. The protrusion portion is protruded from the second lower surface and correspondingly disposed in the recess portion. The through hole penetrates the second metal element via a central part of the protrusion portion. The pressure-receiving portion is correspondingly received in the through hole and is adapted to be pressed and deformed to be riveted to the through hole.

First claim

What is claimed is:

1. A riveting structure comprising:
a first metal element comprising a first upper surface, a pressure-receiving portion and a recess portion, wherein the recess portion is recessed from the first upper surface, and the pressure-receiving portion is protruded from a surface of the recess portion; and
a second metal element comprising a second lower surface and a protrusion portion and having a through hole, wherein the protrusion portion is protruded from the second lower surface and correspondingly disposed in the recess portion, and the through hole penetrates the second metal element corresponding to a central part of the protrusion portion;
wherein the pressure-receiving portion is correspondingly received in the through hole and is adapted to be pressed and deformed to be riveted to a sidewall of the through hole of the second metal element, and no through hole is formed in the first metal element at a position corresponding to the through hole of the second metal element.

2. The riveting structure according to claim 1 , wherein the second metal element further comprises a second upper surface, and further has a recessed space recessed from the second upper surface and interconnected with the through hole.

3. The riveting structure according to claim 2 , wherein when the pressure-receiving portion is correspondingly received in the through hole, a pressure-receiving surface of the pressure-receiving portion is lower than the second upper surface.

4. The riveting structure according to claim 3 , wherein when the pressure-receiving portion is correspondingly received in the through hole, the pressure-receiving surface of the pressure-receiving portion is located in the recessed space.

5. The riveting structure according to claim 2 , wherein the pressure-receiving portion has a diameter D 1 , the recessed space has a diameter D 2 , and D 1 is smaller than D 2 .

6. The riveting structure according to claim 5 , wherein the diameter D 2 satisfies: 4.0 mm≤D 2 ≤7.0 mm.

7. The riveting structure according to claim 2 , wherein the pressure-receiving portion has a height H 1 , a height H 2 is from a surface of the protrusion portion to the second upper surface, and H 1 is smaller than H 2 .

8. The riveting structure according to claim 2 , wherein the through hole has an aperture gradually increasing along a direction from a bottom surface of the protrusion portion to the second upper surface of the second metal element.

9. The riveting structure according to claim 2 , wherein the pressure-receiving portion is riveted to the sidewall of the through hole rather than being riveted to a sidewall of the recessed space.

10. The riveting structure according to claim 1 , wherein the recess portion forms an annular ring surrounding the pressure-receiving portion, and the protrusion portion forms an annular ring surrounding the through hole.

11. The riveting structure according to claim 1 , wherein a maximum diameter of the pressure-receiving portion is commensurate with a minimum aperture of the through hole.

12. A riveting structure comprising:
a first metal element comprising a first upper surface, a pressure-receiving portion and a recess portion, wherein the recess portion is recessed from the first upper surface, and the pressure-receiving portion is protruded from a surface of the recess portion; and
a second metal element comprising a second lower surface, a second upper surface opposite to the second lower surface and a protrusion portion and having a through hole and a recessed space recessed from the second upper surface and interconnected with the through hole;
wherein the protrusion portion is protruded from the second lower surface and correspondingly disposed in the recess portion, and the through hole penetrates the second metal element corresponding to a central part of the protrusion portion;
wherein the pressure-receiving portion of the first metal element is riveted to a sidewall of the through hole rather than being riveted to a sidewall of the recessed space.

13. The riveting structure according to claim 12 , wherein the through hole has an aperture gradually increasing along a direction from a bottom surface of the protrusion portion to the second upper surface of the second metal element.

14. The riveting structure according to claim 12 , wherein a distance from a central axis of the through hole to the sidewall of the recessed space is greater than a distance from the central axis of the through hole to the sidewall of the through hole.

15. A riveting method comprising:
providing a first metal element comprising a first upper surface, a pressure-receiving portion and a recess portion, wherein the recess portion is recessed from the first upper surface, and the pressure-receiving portion is protruded from a surface of the recess portion;
providing a second metal element comprising a second lower surface and a protrusion portion and having a through hole, wherein the protrusion portion is protruded from the second lower surface, and the through hole penetrates the second metal element corresponding to a central part of the protrusion portion;
correspondingly disposing the protrusion portion of the second metal element in the recess portion of the first metal element, wherein the pressure-receiving portion of the first metal element is correspondingly received in the through hole of the second metal element; and
applying a force to the pressure-receiving portion by a punch-riveting device for deforming and riveting the pressure-receiving portion to the sidewall of the through hole, wherein no through hole is formed in the first metal element at a position corresponding to the through hole of the second metal element.

16. The riveting method according to claim 15 , wherein:
in the step of providing the second metal element, the second metal element further comprises a second upper surface, and further has a recessed space recessed from the second upper surface and interconnected with the through hole; and
in the step of applying the force to the pressure-receiving portion by the punch-riveting device, the punch-riveting device enters the recessed space and applies the force to the pressure-receiving portion by a indenter.
