Abstract

An outside door handle arrangement including an electronic sensor for detecting actuation of an outside door handle of a motor vehicle. An electronic circuit, which is assigned to the electronic sensor, is located directly on a piezoelement such that the piezoelement is used as a circuit carrier. Additionally, the piezoelement is used for holding an assigned electronic circuit such that the electronic circuit is mounted on and is electronically connected to the piezoelement.

Claims

1. An outside door handle arrangement for a motor vehicle door locking system comprising:

an outside door handle for opening an assigned motor vehicle door lock;

a piezoelement which is assigned to the outside door handle for detecting actuation of the outside door handle by a hand of an operator; and

an electronic circuit which is assigned to the piezoelement;

wherein the electronic circuit is located on the piezoelement and is carried by it.

2. The outside door handle arrangement as claimed in claim 1, wherein the piezoelement is an electronic component.

3. The outside door handle arrangement as claimed in claim 1, wherein the piezoelement is a conductor arrangement.

4. The outside door handle arrangement as claimed in claim 1, wherein the piezoelement is a circuit board of the electronic circuit.

5. The outside door handle arrangement as claimed in claim 1, wherein the piezoelement has a metal coating.

6. The outside door handle arrangement as claimed in claim 1, wherein the piezoelement contains a ceramic surface.

7. The outside door handle arrangement as claimed in claim 6, wherein the ceramic surface of the piezoelement has a metal coating.

8. The outside door handle arrangement as claimed in claim 1, wherein the piezoelement is provided with a conductor arrangement of the electronic circuit.

9. The outside door handle arrangement as claimed in claim 5, wherein the metal coating is one of a printed on, vapor-deposited, and cemented on coating.

10. The outside door handle arrangement as claimed in claim 8, wherein the conductor arrangement is printed, vapor-deposited, or cemented onto the piezoelement.

11. The outside door handle arrangement as claimed in claim 1, wherein all components of the electronic circuit are carried by the piezoelement.

12. The outside door handle arrangement as claimed in claim 1, wherein at least one component of the electronic circuit is held on the piezoelement by cement.

13. The outside door handle arrangement as claimed in claim 1, wherein at least one component of the electronic circuit is attached with cement onto a conductor arrangement which is formed on the piezoelement.

14. The outside door handle arrangement as claimed in claim 1, wherein a flexible circuit board is cemented onto the piezoelement.

15. The outside door handle arrangement as claimed in claim 1, wherein the piezoelement with the electronic circuit forms an installation unit which is located on the outside door handle.

16. The outside door handle arrangement as claimed in claim 1, wherein the piezoelement with the electronic circuit forms an installation unit which is installed in the door handle.

17. The outside door handle arrangement as claimed in claim 1, wherein the outside door handle arrangement has at least one connecting line which is connected to the electronic circuit formed on the piezoelement.

18. The outside door handle arrangement as claimed in claim 1, wherein the outside door handle arrangement has at least one connecting line which is connected to the piezoelement.

19. The outside door handle arrangement as claimed in claim 1, wherein the piezoelement and the electronic circuit are surrounded by a watertight and water vapor-tight cladding.

20. The outside door handle arrangement as claimed in claim 1, wherein the piezoelement, the electronic circuit, and a section of the connecting line are surrounded by a watertight and water vapor-tight cladding.

21. The outside door handle arrangement as claimed in claim 19, wherein the cladding has a flexible jacket.

22. A method of using a piezoelement for holding an assigned electronic circuit, wherein the electronic circuit is mounted directly on and is electrically connected to the piezoelement.
