Abstract

A vehicle entry device is designed to equip a vehicle and may include: a housing defining a cavity and adapted to be fixed to the vehicle; and an electronics module disposed in the cavity, including: a printed circuit board; an antenna connected to the printed circuit board and configured to capture a NFC signal, wherein the antenna includes windings directly arranged on the printed circuit board; an NFC receiver connected to the printed circuit board, in communication with the antenna and configured to receive the NFC signal from the antenna; and a processing element connected to the printed circuit board, in communication with the NFC receiver and configured to provide a control signal to a control system equipping the vehicle, based on the NFC signal transmitted by the NFC receiver, said control signal allowing access to the vehicle. A vehicle trim component may be equipped with such vehicle entry device.

First claim

The invention claimed is:

1. A vehicle entry device, comprising:
a pillar capping that includes two layers of two different materials including an opaque layer and a transparent or translucent layer;
and wherein the vehicle entry device includes:
a housing defining a cavity; and
an electronics module disposed in the cavity, including:
a) a printed circuit board;
b) an antenna connected to the printed circuit board and configured to capture a NFC signal, wherein the antenna includes windings directly arranged on the printed circuit board;
c) a NFC receiver connected to the printed circuit board, in communication with the antenna and configured to receive the NFC signal from the antenna;
d) a processing element connected to the printed circuit board, in communication with the NFC receiver and configured to provide a control signal to a control system equipping the vehicle, based on the NFC signal transmitted by the NFC receiver, said control signal allowing access to the vehicle;
e) a light source connected to the printed circuit board and in communication with the NFC receiver, and
f) a light guide positioned before the light source,

wherein the housing of the vehicle entry device is attached to a mounting surface of the pillar capping, and wherein an illumination portion of the pillar capping has a transparent or translucent area which is formed by the transparent or translucent layer and is devoid of the opaque layer, and wherein the light source emits light through the light guide of the vehicle entry device, then through the illumination portion of the pillar capping, when the NFC receiver receives the NFC signal from the antenna.

2. The vehicle entry device according to claim 1 , wherein the processing element and the NFC receiver are connected to a first side portion of the printed circuit board, while the antenna is connected to a second side portion of the printed circuit board opposite the first side portion.

3. The vehicle entry device according to claim 1 , wherein the processing element, the NFC receiver and the antenna are connected to a same face of the printed circuit board.

4. The vehicle entry device according to claim 1 , wherein the antenna does not surround the processing element.

5. The vehicle entry device according to claim 1 , wherein the housing has a front part and a rear part defining the cavity for receiving the electronics module, the rear part being designed to be fixed to the pillar capping.

6. The vehicle entry device according to claim 5 , wherein the front part is a transparent cover.

7. The vehicle entry device according to claim 1 , wherein the antenna includes three windings.

8. The vehicle entry device according to claim 1 , wherein the NFC receiver includes a capacitor and an EMC filter.

9. The vehicle entry device according to claim 1 , wherein the antenna surrounds the light source.

10. The vehicle entry device according to claim 1 , further comprising a ferrite sheet disposed on a rear outer surface of the housing.

11. The vehicle entry device according to claim 10 , wherein the ferrite sheet covers an area of the rear outer surface of the housing corresponding to an area covered by the antenna inside the housing.

12. The vehicle entry device according to claim 10 , wherein the ferrite sheet covers an area of the rear outer surface of the housing larger than an area covered by the antenna inside the housing.

13. The vehicle entry device according to claim 10 , wherein the ferrite sheet is disposed opposite the processing element, the NFC receiver and the antenna in relation with the printed circuit board.

14. The vehicle entry device according to claim 10 , wherein the ferrite sheet is attached to the housing by an adhesive.

15. The vehicle entry device according to claim 1 , wherein a seal member is disposed between the mounting surface of the vehicle trim component pillar capping and the housing of the vehicle entry device.

16. The vehicle entry device according to claim 1 , wherein the pillar capping is provided with a marking visible from outside the vehicle, and-wherein the light source backlights the marking when the NFC receiver receives the NFC signal from the antenna.

17. The vehicle entry device according to claim 1 , wherein at least a portion of the housing is transparent or translucent to allow light transmission therethrough.

18. The vehicle entry device according to claim 17 , wherein the light guide is a separate element positioned between the light source and the transparent or translucent portion of the housing.

19. The vehicle entry device according to claim 17 , wherein the light guide is formed by the transparent or translucent portion of the housing.

20. The vehicle entry device according to claim 16 , wherein the marking is a transparent area located within an opaque area.

21. The vehicle entry device according to claim 20 , wherein the pillar capping has a front side and a rear side, and the mounting surface is at least part of the rear side, and, at the front side, the opaque area in which the marking is located has exactly the same aspect as the remaining surface of the pillar capping.
