Emblem for vehicles
Emblem for vehicles, comprising a decoration layer; at least one lighting element that illuminates the decoration layer; an electrical power generator that feeds electric power to the at least one lighting element, wherein the electrical power generator includes a rotor comprising a support disc for at least one magnet; and a stator comprising at least one printed circuit board provided with windings. It permits to provide an emblem in which a power generator is optimized to be compatible in the axial direction with the available space, which is very small behind the front cover.
1. An emblem for vehicles, comprising:
a decoration layer;
at least one lighting element that illuminates the decoration layer;
an electrical power generator that generates and feeds electric power to the at least one lighting element,
wherein the electrical power generator includes:
a rotor comprising a support disc, the support disc having at least one magnet thereon; and
a stator comprising at least one printed circuit board, the at least one printed circuit board having windings as a part of traces that generate the electric power when the support disc rotates,
wherein said at least one printed circuit board comprises a first printed circuit board having a first surface and a second surface, the first surface facing the support disc, the second surface being opposite to the first surface, the emblem further comprising a magnetic conducting layer disposed on the second surface of the first printed circuit board and configured to improve transformation of magnetic field into electric power.
2. The emblem for vehicles according to claim 1 , wherein the windings of the printed circuit board or of each printed circuit board are connected in series.
3. The emblem for vehicles according to claim 1 , wherein the emblem also comprises an eccentric weight.
4. The emblem for vehicles according to claim 1 , wherein a spacer is placed between the support disc and the, or each, printed circuit board.
5. The emblem for vehicles according to claim 1 , wherein the stator comprises two printed circuit boards, the windings of each printed circuit board are connected to each other by pins.
6. The emblem for vehicles according to claim 1 , wherein the at least one lighting element is mounted on the at least one printed circuit board.
7. The emblem for vehicles according to claim 1 , wherein the emblem also comprises a light guide.
8. The emblem for vehicles according to claim 7 , wherein the light guide is mounted on the magnetic conducting layer.
9. The emblem for vehicles according to claim 1 , wherein the support disc comprises magnets at both sides.
10. The emblem for vehicles according to claim 1 , wherein the emblem comprises a housing formed by a base and a cover.
11. The emblem for vehicles according to claim 10 , wherein the at least one printed circuit board of the stator further comprises a second printed circuit board, the second printed circuit board having a first surface facing the support disc and a second surface opposite to the first surface of the second printed circuit board, the second printed circuit board being disposed farther from the cover than the first printed circuit board in a rotational axis of the rotor.
12. The emblem for vehicles according to claim 1 , wherein a stationary assembly comprises the decoration layer and the stator.
13. The emblem for vehicles according to claim 11 , further comprising:
a second magnetic conducting layer disposed on the second surface of the second printed circuit board.
