Abstract

An electronic circuit board unit for an electronic module installed in a vehicle rear view device. The electronic circuit board unit has a base plate, at least one printed circuit board, and at least one plug connection for an electronic and physical connection between the printed circuit board and the base plate. The electronic circuit board has at least one first receiver for mounting an electronic consumer unit of the electronic module and being attachable or attached to the base plate or to one of the at least one printed circuit board. There is at least one second connector attachable or attached to the base plate or to the at least one printed circuit board for connecting at least one further electronic consumer unit of the electronic module to the driver circuit of the base plate. This configuration provides either n printed circuit boards and n+1 of electronic consumer units, with n being an integer number of 1 and above, or a plurality of printed circuit boards is provided, with each circuit board comprising at least one first receiver and at least one second connector.

First claim

What is claimed is:

1. An electronic circuit board unit for an electronic module installed in a vehicle rear view device,
with an, essentially plane, base plate, comprising at least one driver circuit, with a first connector for directly or indirectly connecting the base plate with at least one power supply,
with at least one, essentially plane, printed circuit board, which is disposable or disposed parallel, angular or cross to the base plate and which is spaced to the base plate, in particular in a manner having no direct contact to the base plate,
with at least one plug connection for electronically and physically connecting between the printed circuit board and the base plate, and
with at least one first receiver for mounting an electronic consumer unit of the electronic module and being attachable or attached to the base plate or to one of the at least one printed circuit board,

wherein at least one second connector attachable or attached to the base plate or to the at least one printed circuit board for connecting at least one further electronic consumer unit of the electronic module to the driver circuit of the base plate, such that
either n printed circuit boards and n+1 of electronic consumer units are comprised, with n being an integer number of 1 and above, or
a plurality of printed circuit boards is provided, with each circuit board comprising at least one first receiver and at least one second connector, and

wherein the electronic module is in the form a light module for a vehicle rear view device with the at least one power supply and the at least one electronic consumer unit.

2. The electronic circuit board unit according to claim 1 , wherein the base plate comprises an electronic central unit (ECU).

3. The electronic circuit board unit according to claim 1 , wherein the at least one plug connection comprises an electrical conducting part reaching connection by clipping.

4. The electronic circuit board unit according to claim 1 , wherein at least one of the at least one printed circuit board comprises a puzzle printed circuit board.

5. The electronic circuit board unit according to claim 1 , wherein a plurality of printed circuit boards, with at least one of the plurality of printed circuit boards comprises the first connector.

6. The electronic circuit board unit according to claim 1 , wherein
the plurality of printed circuit boards is disposable or disposed parallel to the base plate and is spaced to the base plate and to each other, in particular in a manner having no direct contact to the base plate and to each other, and
there is a plurality of plug connections for an electronic and physical connection between the respective printed circuit boards and the base plate.

7. The electronic circuit board unit according to claim 1 , wherein n electronic consumer units are connected to the n printed circuit boards and one electronic consumer unit is connected to the base plate.

8. The electronic circuit board unit according to claim 1 , wherein at least one electric line connecting at least one electronic consumer unit with at least one second connector.

9. The electronic circuit board unit according to claim 1 , wherein the at least one driver circuit comprise a first driver circuit and a second driver circuit, both comprising the same configuration and both connected to each other to operate on redundancy.

10. The electronic circuit board unit according to claim 1 , wherein at least one of the at least one printed circuit board and/or the base plate comprises a carrier, circuit paths attached to the carrier and electric parts, as integrated circuits (IC), condensers and/or resistors.

11. The electronic circuit board unit according to claim 1 , wherein
a housing containing the base plate, the at least one printed circuit board and the at least one plug connection in its cavity, and
at least one, in particular a plurality, of recesses to enable an electronic and physical connection between base plate and the at least one power supply and between the at least one second connector and the at least one electronic consumer.

12. The electronic circuit board unit according to claim 11 , wherein
at least one of the at least one printed circuit board and/or the base plate comprises a carrier, circuit paths attached to the carrier and electric parts, as integrated circuits (IC), condensers and/or resistors; and
at least one inner surface of the housing comprise a functional surface being at least a part of the carrier or being the carrier entirety of the at least one printed circuit board and/or of the base plate.

13. The electronic circuit board unit according to claim 1 , wherein the at least one electronic consumer unit of the electronic module comprises a side turn indicator (STI), a blind spot detection (BSD), a logo lamp, a door handle and/or an approach light.

14. A rear view device for a vehicle, comprising the electronic module and/or the electronic circuit board unit according to claim 1 , and comprising an outside or inside rear view mirror and/or a camera.
