Abstract

Devices and systems are provided to isolate and/or reduce vibration from a charging panel. A system for reducing vibration between a charging panel of an electric vehicle and the electric vehicle may include a charging panel, an armature coupled to the charging panel, and a floating section, wherein the armature is between the floating section and the charging panel.

Claims (61)

1. A system for reducing vibration in an electric vehicle, the system comprising:

a charging panel;

an armature assembly coupled to the electric vehicle and the charging panel, the armature assembly including a floating section that isolates vibration between the charging panel and the electric vehicle, wherein the floating section includes a first portion coupled to one of the electric vehicle or the charging panel and a second portion coupled to the other one of the electric vehicle or the charging panel,

wherein the first portion includes a T-shaped element having a T-top that is substantially enclosed by the second portion and a T-leg that extends away from the T-top and that protrudes from the second portion,

wherein, in a cross-sectional view, the second portion conforms to a shape of the T-top to substantially enclose the T-top; and

a plurality of magnet assemblies, each magnet assembly of the plurality of magnet assemblies including a first magnet coupled to the first portion and a second magnet coupled to the second portion opposite the first magnet with like poles oriented toward each other,

wherein a first set of the plurality of magnet assemblies is located closer to a first end of the T-top than a second end of the T-top that is opposite the first end, and

wherein a second set of the plurality of magnet assemblies is located closer to the second end of the T-top than the first end.

2. The system of claim 1 , wherein the first portion does not touch the second portion, wherein top and bottom surfaces of the T-top extend in a first direction that is substantially parallel with a top surface of the charging panel, and wherein the T-leg extends in a second direction, substantially perpendicular to the first direction.

3. The system of claim 2 ,

wherein the first set of the plurality of magnet assemblies includes:

a first magnet assembly coupled to the first end of the T-top;

a second magnet assembly coupled to a top of the T-top toward the first end of the T-top, wherein the top of the T-top is adjacent to the T-leg; and

a third magnet assembly coupled to a bottom of the T-top toward the first end of the T-top, wherein the bottom of the T-Top is opposite the top of the T-top; and

wherein the second set of the plurality of magnet assemblies includes:

a fourth magnet assembly coupled to the second end of the T-top;

a fifth magnet assembly coupled to the top of the T-top toward the second end of the T-top; and

a sixth magnet assembly coupled to the bottom of the T-top toward the second end of the T-top.

4. The system of claim 2 , further comprising:

a plurality of pressurization devices, wherein each pressurization device of the plurality of pressurization devices pressurizes a liquid between the first portion and the second portion.

5. The system of claim 2 , further comprising:

a plurality of pressurization devices, wherein each pressurization device of the plurality of pressurization devices pressurizes a gas between the first portion and the second portion.

6. The system of claim 5 , wherein the gas is atmospheric air.

7. The system of claim 1 , wherein at least one of the first portion and the second portion includes a plurality of floating devices.

8. The system of claim 7 , wherein the plurality of floating devices comprises a plurality of pressurization devices, wherein each pressurization device of the plurality of pressurization devices pressurizes a liquid between the first portion and the second portion.

9. The system of claim 7 , wherein the plurality of floating devices comprises a plurality of pressurization devices, wherein each pressurization device of the plurality of pressurization devices pressurizes a gas between the first portion and the second portion.

10. The system of claim 9 , wherein the gas is atmospheric air.

11. The system of claim 7 , wherein the first portion does not touch the second portion.

12. The system of claim 7 , wherein the first portion is suspended within the second portion.

13. The system of claim 7 , further comprising:

an actuator rod coupled to the floating section, the actuator rod being configured to move the armature assembly.

14. The system of claim 1 , further comprising:

an actuator rod coupled to the floating section, the actuator rod being configured to move the armature assembly.

15. The system of claim 1 , wherein the charging panel wirelessly accepts energy transferred from a charging source.

16. A system for an electric vehicle comprising:

a charging panel;

a floating section coupled to the charging panel and that isolates vibration between the charging panel and the electric vehicle,

wherein the floating section includes a first portion coupled to one of the electric vehicle or the charging panel and a second portion coupled to the other one of the electric vehicle or the charging panel,

wherein the first portion includes a T-shaped element having a T-top that is substantially enclosed by the second portion and a T-leg that extends away from the T-top and that protrudes from the second portion, and

wherein, in a cross-sectional view, the second portion conforms to a shape of the T-top to substantially enclose the T-top; and

a plurality of magnet assemblies, each magnet assembly of the plurality of magnet assemblies including a first magnet coupled to the first portion and a second magnet coupled to the second portion opposite the first magnet with like poles oriented toward each other,

wherein a first set of the plurality of magnet assemblies are located closer to a first end of the T-top than a second end of the T-top that is opposite the first end, and

wherein a second set of the plurality of magnet assemblies are located closer to the second end of the T-top than the first end.

17. A floating armature assembly comprising:

a charging panel;

a floating section coupled to the charging panel and that isolates vibration between the charging panel and an object mounted to the floating section,

wherein the floating section includes a first portion coupled to one of the object or the charging panel and a second portion coupled to the other one of the object or the charging panel,

wherein the first portion includes a T-shaped element having a T-top that is substantially enclosed by the second portion and a T-leg that extends away from the T-top and that protrudes from the second portion,

wherein, in a cross-sectional view, the second portion conforms to a shape of the T-top to substantially enclose the T-top, and

wherein the first portion and the second portion include a structure to isolate the vibration between the charging panel and the object mounted to the floating section,

wherein the structure includes a plurality of magnet assemblies, each magnet assembly of the plurality of magnet assemblies including a first magnet coupled to the first portion and a second magnet coupled to the second portion opposite the first magnet with like poles oriented toward each other,

wherein a first set of the plurality of magnet assemblies is located closer to a first end of the T-top than a second end of the T-top that is opposite the first end, and

wherein a second set of the plurality of magnet assemblies is located closer to the second end of the T-top than the first end.
