Abstract

Electrical connector assemblies mountable on a tire of a wheel of a vehicle are described. An electrical connector assembly may include one or more electrical conductors, a respective electrical conductor extending from an inside surface of the tire to an outside surface of the tire. Tire assemblies including at least partially embedded electrical connector assemblies and wheel assemblies including such tire assemblies are also described.

First claim

What is claimed is:

1. A tire assembly, comprising:
a tire having an inside surface, an outside surface opposite to the inside surface, and a tire bead region, wherein the tire has an inner side wall, an outside side wall, and a tread region coupled to the inner side wall and the outside side wall and located between the inner side wall and the outside side wall;
two or more electrical conductors extending from the inside surface of the tire to at least the tire bead region, including a first electrical conductor and a second electrical conductor electrically insulated from the first electrical conductor, wherein each electrical conductor of the two or more electrical conductors extends from the outside surface of the tire to the inside surface of the tire on a particular side wall selected between the inner side wall and the outside side wall; and
two or more internal electrical conductors extending circumferentially on the inside surface of the tire, including (i) a first internal electrical conductor that is electrically coupled with a first group of electrical conductors extending from the inside surface of the tire to the outside surface of the tire, including the first electrical conductor, and (ii) a second internal electrical conductor that is electrically coupled with a second group of electrical conductors extending from the inside surface of the tire to the outside surface of the tire, including the second electrical conductor, wherein the first group of electrical conductors is mutually exclusive from the second group of electrical conductors.

2. The tire assembly of claim 1 , wherein:
the two or more electrical conductors are conductive films located on a surface of the tire.

3. The tire assembly of claim 1 , further comprising:
an insulator layer positioned adjacent to a bead area of the tire coupled to the particular side wall so that one or more portions of the two or more electrical conductors are located between the insulator layer and the bead area of the tire.

4. The tire assembly of claim 1 , wherein:
the two or more electrical conductors extend radially on the outside surface of the tire.

5. The tire assembly of claim 1 , further comprising:
two or more external electrical conductors extending circumferentially on the outside surface of the tire, including (i) a first external electrical conductor that is electrically coupled with a first group of external electrical conductors extending from the inside surface of the tire to the outside surface of the tire, including the first electrical conductor, and (ii) a second external electrical conductor that is electrically coupled with a second group of external electrical conductors extending from the inside surface of the tire to the outside surface of the tire, including the second electrical conductor, wherein the first group of external electrical conductors is mutually exclusive from the second group of external electrical conductors.

6. A wheel assembly, comprising:
a wheel with two or more connecting electrical conductors; and
the tire assembly of claim 1 , the tire assembly being mounted on the wheel,
wherein the two or more connecting electrical conductors are configured to contact with the two or more electrical conductors of the tire assembly.

7. The wheel assembly of claim 6 , wherein:
the wheel also includes two or more rim electrical conductors extending circumferentially in a rim region of the wheel, including a first rim electrical conductor electrically coupled with a first connecting electrical conductor of the two or more connecting electrical conductors and a second rim electrical conductor electrically coupled with a second connecting electrical conductor of the two or more connecting electrical conductors, wherein the second rim electrical conductor is electrically isolated from the first rim electrical conductor.

8. A wheel assembly, comprising:
a wheel;
the tire assembly of claim 1 , the tire assembly being mounted on the wheel;
an energy harvester mounted on the wheel; and
one or more electrical components electrically connected to the energy harvester via the two or more electrical conductors.

9. A method of making a tire assembly, the method comprising:
providing a tire having an inside surface and an outside surface opposite to the inside surface, wherein the tire has an inner side wall, an outside side wall, and a tread region coupled to the inner side wall and the outside side wall and located between the inner side wall and the outside side wall;
placing two or more electrical conductors, including a first electrical conductor and a second electrical conductor electrically insulated from the first electrical conductor, so that the two or more electrical conductors extend from the inside surface of the tire and the outside surface of the tire; and
placing two or more internal electrical conductors extending circumferentially on the inside surface of the tire, including (i) a first internal electrical conductor that is electrically coupled with a first group of electrical conductors extending from the inside surface of the tire to the outside surface of the tire, including the first electrical conductor, and (ii) a second internal electrical conductor that is electrically coupled with a second group of electrical conductors extending from the inside surface of the tire to the outside surface of the tire, including the second electrical conductor, wherein the first group of electrical conductors is mutually exclusive from the second group of electrical conductors.

10. The method of claim 9 , wherein:
placing the two or more electrical conductors includes depositing a conductive ink or conductive film to form one or more portions of the two or more electrical conductors on the tire.

11. A tire assembly, comprising:
a tire defining a hollow channel;
a liquid metal filling at least a portion of the hollow channel defined in the tire;
one or more external conductive stubs electrically coupled with the liquid metal within the hollow channel and extending to an outside surface of the tire; and
one or more internal conductive stubs electrically coupled with the liquid metal within the hollow channel and extending to an inside surface of the tire.

12. A wheel assembly, comprising:
a wheel;
the tire assembly of claim 11 , the tire assembly being mounted on the wheel;
an energy harvester mounted on the wheel; and
one or more electrical components electrically connected to the energy harvester via the one or more external conductive stubs.

13. A tire assembly, comprising:
a tire having an inside surface, an outside surface opposite to the inside surface, and a tire bead region, wherein the tire has an inner side wall, an outside side wall, and a tread region coupled to the inner side wall and the outside side wall and located between the inner side wall and the outside side wall;
two or more electrical conductors extending from the inside surface of the tire to at least the tire bead region, including a first electrical conductor and a second electrical conductor electrically insulated from the first electrical conductor, wherein each electrical conductor of the two or more electrical conductors extends from the outside surface of the tire to the inside surface of the tire on a particular side wall selected between the inner side wall and the outside side wall; and
two or more external electrical conductors extending circumferentially on the outside surface of the tire, including (i) a first external electrical conductor that is electrically coupled with a first group of electrical conductors extending from the inside surface of the tire
