Abstract

A vehicle accessory may include an accessory body configured to operably couple to the vehicle, a power transfer assembly configured to operably couple a first power source at the vehicle to the accessory body to transfer electrical power to the accessory body, and an electroluminescent material disposed at the accessory body to emit light when powered. The power transfer assembly may transfer the electrical power to the accessory body responsive to installation in or operation of the vehicle, and the electrical power may excite the electroluminescent material to emit light.

Claims (49)

1 . A vehicle accessory for a vehicle, the vehicle accessory comprising:

an accessory body configured to operably couple to the vehicle;

a power transfer assembly configured to operably couple a first power source at the vehicle to the accessory body to transfer electrical power to the accessory body; and

an electroluminescent material disposed at the accessory body to emit light when powered;

wherein the power transfer assembly transfers the electrical power to the accessory body responsive to installation in or operation of the vehicle,

wherein the electrical power excites the electroluminescent material to emit light,

wherein the vehicle accessory and the accessory body are flexible, and

wherein a control circuit disposed at the accessory body and printed via conductive ink printing to maintain flexibility transfers the electrical power to excite the electroluminescent material to emit light.

2 . The vehicle accessory of claim 1 , wherein the vehicle accessory includes a battery that receives and stores the electrical power transferred by the power transfer assembly, and

wherein the vehicle accessory utilizes the electrical power stored in the battery to excite the electroluminescent material.

3 . The vehicle accessory of claim 1 , wherein the vehicle accessory includes a piezoelectric element to provide electrical power via the control circuit to excite the electroluminescent material responsive to vibration of the accessory body.

4 . The vehicle accessory of claim 1 , wherein the power transfer assembly transfers power to the accessory body via induction and the control circuit.

5 . The vehicle accessory of claim 4 , wherein the power transfer assembly is disposed at a location of operable coupling between the accessory body and vehicle.

6 . The vehicle accessory of claim 1 , wherein the electroluminescent material is applied on a layer of the accessory body via a coating, and

wherein the coating is waterproof.

7 . The vehicle accessory of claim 1 , wherein the power transfer assembly transfers power wirelessly to the accessory body.

8 . The vehicle accessory of claim 1 , wherein the accessory body receives the electrical power from multiple sources,

wherein the multiple sources include the first power source at the vehicle and a second power source

disposed at the accessory body, and

wherein the control circuit operably couples to both the first power source and the second power source.

9 . The vehicle accessory of claim 1 , wherein the vehicle accessory is a cargo mat, floor mat, wheel well lining, or mud flap.

10 . The vehicle accessory of claim 1 , wherein responsive to an illumination trigger, the electrical power excites the electroluminescent material.

11 . The vehicle accessory of claim 10 , wherein the illumination trigger is a signal transferred from a control module of the vehicle, and

wherein the signal is transferred automatically based on a vehicle event.

12 . The vehicle accessory of claim 10 , wherein the illumination trigger is sent through a remotely connected device.

13 . The vehicle accessory of claim 1 , wherein the power transfer assembly is disposed at a location of the vehicle that aligns a transmitter of the power transfer assembly with a receiver of the accessory body responsive to engagement of the accessory body and the vehicle.

14 . A vehicle accessory for a vehicle, the vehicle accessory comprising:

an accessory body configured to operably couple to the vehicle;

a power transfer assembly configured to operably couple a first power source at the vehicle to the accessory body to transfer electrical power to the accessory body; and

a control circuit disposed at the accessory body and configured to transfer the electrical power to emit light from the accessory body,

wherein the power transfer assembly transfers the electrical power to the accessory body responsive to installation in or operation of the vehicle,

wherein the vehicle accessory and the accessory body are flexible, and

wherein the control circuit is printed via conductive ink printing to maintain flexibility.

15 . The vehicle accessory of claim 14 , wherein the control circuit transfers the electrical power to excite an electroluminescent material to emit light.

16 . The vehicle accessory of claim 15 , wherein the vehicle accessory includes a battery that receives and stores the electrical power transferred by the power transfer assembly, and

wherein the vehicle accessory utilizes the electrical power stored in the battery to excite the electroluminescent material.

17 . The vehicle accessory of claim 13 , wherein the electroluminescent material is applied on a layer of the accessory body via a coating, and

wherein the coating is waterproof.

18 . A vehicle accessory for a vehicle, the vehicle accessory comprising:

an accessory body configured to operably couple to the vehicle;

a power source disposed at the accessory body to transfer electrical power to the accessory body;

an electroluminescent material disposed at the accessory body to emit light when powered, and

a control circuit disposed at the accessory body and configured to transfer the electrical power to the electroluminescent material,

wherein the power source transfers electrical power to the accessory body responsive to installation in the vehicle, operation of the vehicle, or an illumination trigger,

wherein the electrical power excites the electroluminescent material to emit light,

wherein the vehicle accessory and the accessory body are flexible, and

wherein the control circuit is printed via conductive ink printing to maintain flexibility.

19 . The vehicle accessory of claim 18 , wherein the vehicle accessory is formed via an additive manufacturing process,

wherein the control circuit and the electroluminescent material are added after formation of the accessory body during the additive manufacturing process.
