Power distribution system mountable on a vehicle wheel
Electrical connectors mountable on wheels are described. An electrical connector may include a sleeve sized for mounting on a barrel of a wheel. The sleeve defines one or more channels. The electrical connector may also include one or more hollow spokes mechanically coupled with the sleeve, and one or more electrical conductors. An electrical conductor extends from a portion of the sleeve corresponding to a bead seat region through the one or more channels and a hollow spoke for electrically coupling with an electrical module positioned on a tread region of a tire mounted on the wheel. Electrical devices including such electrical connectors and electrical devices including other electrical connectors are also described.
1. An electrical connector, comprising:
a sleeve sized for mounting on a rim region of a wheel, the sleeve defining one or more channels, wherein a first side of the sleeve extends at least to a first bead seat region of the wheel;
one or more hollow spokes mechanically coupled with the sleeve; and
one or more electrical conductors, wherein at least a first electrical conductor of the one or more electrical conductors extends from a first portion of the sleeve corresponding to the first bead seat region through the one or more channels and a first hollow spoke of the one or more hollow spokes for electrically coupling with a first electrical module positioned on a first tread region of a tire mounted on the wheel.
2. The electrical connector of claim 1 , wherein:
a second side of the sleeve, opposite to the first side of the sleeve, extends at least to a second bead seat region of the wheel that is opposite to the first bead seat region of the wheel; and
the one or more electrical conductors include a second electrical conductor extending from a second portion of the sleeve corresponding to the second bead seat region.
3. The electrical connector of claim 2 , wherein:
the second electrical conductor extends through the one or more channels and the first hollow spoke of the one or more hollow spokes for electrically coupling with the first electrical module positioned on the first tread region of the tire mounted on the wheel.
4. The electrical connector of claim 2 , wherein:
the second electrical conductor extends through the one or more channels and a second hollow spoke of the one or more hollow spokes for electrically coupling with a second electrical module positioned on a second tread region of the tire mounted on the wheel.
5. The electrical connector of claim 4 , wherein:
the one or more electrical conductors include at least a third electrical conductor, distinct from the second electrical conductor, extending from the second portion of the sleeve corresponding to the second bead seat region through the one or more channels and the second hollow spoke of the one or more hollow spokes.
6. The electrical connector of claim 2 , wherein:
the one or more electrical conductors include at least a fourth electrical conductor, distinct from the first electrical conductor, extending from the first portion of the sleeve corresponding to the first bead seat region through the one or more channels and the first hollow spoke of the one or more hollow spokes.
7. The electrical connector of claim 1 , wherein:
the sleeve has a first surface facing the rim region and a second surface facing away from the rim region; and
at least one channel is defined on the first surface of the sleeve.
8. The electrical connector of claim 1 , further comprising:
a first guide positioned for coupling with the first hollow spoke and the first electrical module and for allowing the first electrical conductor to extend through the first guide to the first electrical module.
9. The electrical connector of claim 8 , wherein the first guide is slidably coupled with the first hollow spoke.
10. The electrical connector of claim 1 , wherein:
the one or more electrical conductors include an electrical conductor extending from a portion of the sleeve corresponding to a bead seat region of the wheel to the first electrical module along an inner surface of a tire mounted on the wheel.
11. An electrical device, comprising:
the electrical connector of claim 1 ; and
one or more energy harvesters, including a first energy harvester electrically coupled with the first electrical conductor.
12. The electrical device of claim 11 , wherein:
the first energy harvester is mounted adjacently to the first bead seat region of the wheel.
13. The electrical device of claim 11 , wherein:
the one or more energy harvesters include a second energy harvester mounted adjacently to a second bead seat region of the wheel that is opposite to the first bead seat region of the wheel.
14. The electrical device of claim 11 , further comprising:
the first electrical module electrically coupled with the first electrical conductor.
15. The electrical device of claim 14 , wherein:
the first electrical module includes one or more sensors.
16. The electrical device of claim 11 , further comprising:
a control module mounted on the sleeve, wherein the control module includes one or more processors electrically coupled with at least one electrical conductor of the one or more electrical conductors.
17. The electrical device of claim 15 , wherein:
the one or more processors are electrically coupled with the first electrical module for receiving sensor signals from one or more sensors in the first electrical module.
18. The electrical device of claim 16 , wherein:
the control module includes one or more sensors.
