Abstract

A component connection includes a first vehicle component which has a male fixing element projecting from the first vehicle component, and a second vehicle component, which has a female fixing element that is intended for receiving the male fixing element. The male fixing element is inserted into the female fixing element in an insertion direction. The male fixing element has a functional head, which has partially or completely the shape of a sphere or partially or completely a shape similar to a sphere, and the male fixing element has a foot region, which is connected to the second component in a positive locking manner. The functional head has an excessive dimension in relation to the female fixing element in essence transversely to the insertion direction, so that the two vehicle components can be clamped together in a detachable manner at the fixing elements.

First claim

What is claimed is:

1. A component connection, comprising:
a first component, which has a male fixing element projecting from the first component;
a second component, which has a female fixing element configured to receive the male fixing element, wherein the male fixing element is insertable into the female fixing element in an insertion direction; and
wherein the male fixing element comprises:
a functional head having at least partially a spherical shape, the functional head having an excessive dimension in relation to the female fixing element essentially transverse to the insertion direction so as to interfere when inserted, wherein the first and second components are clamped together at the male and female fixing elements, and
a foot region extending from and integrally connected to the functional head, the foot region being connected to the first component in a positive locking manner.

2. The component connection according to claim 1 , wherein the first component is a first vehicle component and the second component is a second vehicle component.

3. The component connection according to claim 1 , wherein the female fixing element comprises a passage hole formed in the second component.

4. The component connection according to claim 3 , wherein the passage hole has a non-circular shape.

5. The component connection according to claim 3 , wherein the passage hole is configured to have one of a substantially square or substantially triangular shape.

6. The component connection according to claim 3 , further comprising at least one flexible clamping element projecting from the second component and being arranged on an edge of the passage hole; and
wherein the at least one flexible clamping element is operatively configured to exert a clamping force acting essentially transverse to the insertion direction on an outer surface of the male fixing element.

7. The component connection according to claim 6 , wherein the at least one clamping element extends behind the male fixing element.

8. The component connection according to claim 6 , wherein the at least one clamping element comprises a clamping collar extending along an entire edge of the passage hole.

9. The component connection according to claim 6 , wherein a plurality of clamping collars are spaced apart from one another in a circumferential direction along an edge of the passage hole, the plurality of clamping collars forming the clamping element that exerts the clamping force on an outer peripheral section of the male fixing element.

10. The component connection according to claim 6 , wherein the at least one flexible clamping element projects from the second component either in the insertion direction or against the insertion direction.

11. The component connection according to claim 6 , wherein the at least one flexible clamping element comprises a bent section of the second component.

12. The component connection according to claim 3 , wherein the passage hole is a punched passage hole in the second component.

13. The component connection according to claim 1 , wherein the first and second components are fixed immovably relative to one another in directions transverse to the insertion direction in a region of the male and female fixing elements.

14. The component connection according to claim 1 , further comprising an additional male fixing element and an additional female fixing element; and
wherein the additional male fixing element has an at least partial spherical shape and is insertable into the additional female fixing element in one or a same insertion direction.

15. The component connection according to claim 14 , wherein the additional female fixing element comprises an oblong passage hole in which the additional male fixing element is slidable in a longitudinal direction of the oblong passage hole.

16. The component connection according to claim 1 , wherein at least one of the first component and the second component is a sheet metal component.

17. The component connection according to claim 1 , wherein at least one of first component and the second component is a vehicle body component.

18. The component connection according to claim 1 , wherein the male fixing element is made completely of metal.

19. The component connection according to claim 1 , further comprising an additional connection by which the first and second components are securely connected directly to one another.

20. The component connection according to claim 1 , wherein the foot region is configured as a self-piercing rivet, and forms a self-piercing riveting connection with the first component.

21. A method for preassembling in a detachable manner at least two vehicle components, the method comprising the acts of:
providing a male fixing element on one of the two components, the male fixing element having a functional head at least partially in a spherical shape and a foot region extending from and integrally connected to the functional head, the foot region being connected to the first component in a positive locking manner via a cold joining process;
providing a female fixing element on another of the two vehicle components, the female fixing element comprising a passage hole provided in the other component; and
inserting the male fixing element of the one component into the female fixing element of the other component in an insertion direction, the functional head of the male fixing element having an excessive dimension in relation to the female fixing element essentially transverse to the insertion direction so as to interfere during the inserting, wherein the male fixing element is securely clamped on the female fixing element to preassemble the two components in the detachable manner.

22. The component connection according to claim 1 , wherein the foot region is configured as a rivet, and forms a riveted connection with the first component.

23. The method according to claim 21 , wherein the foot region is configured as a rivet, the method further comprising:
riveting the foot region to the first component.

24. The method according to claim 21 , wherein the foot region is configured as a self-piercing rivet, the method further comprising:
self-pierce riveting the foot region to the first component.
