Abstract

A mounting assembly for transferring electrical power to an inductively powered device is contemplated, with a plurality of magnets positioned inside the mounting assembly includes for magnetically attracting and retaining the inductively powered device against a face plate, and for axially aligning the inductive power receiver of the inductive powered device with the inductive coil assembly inside the mounting assembly. A mounting support member is attached to the back plate of the mounting housing with adjustable joint for adjusted the orientation of the mounting housing relative to the mounting support member. The magnets retain the inductively powered device against the face plate and in the correct orientation with the inductive coil assembly even against forces which would otherwise disturb the inductive coupling, permitting use of the mounting assembly to transfer power in non-horizontal orientations and in moving vehicles.

First claim

What is claimed is:

1. A mounting assembly for an inductively powered device having an inductive power receiver and at least a magnetically receptive portion, the mounting assembly comprising:
a mounting housing comprising a face plate, a back plate, and a mounting plate between the face plate and the back plate;
a mounting support member attached to the back plate of the mounting housing, the mounting support member having an adjustable joint for adjusting the orientation of the mounting housing;
a plurality of magnets attached to the mounting plate for magnetically attracting at least the magnetically receptive portion of the inductively powered device and retaining the inductively powered device against the face plate with the mounting housing being in any orientation relative to the mounting support member; and
an inductive coil assembly attached to the mounting plate and electrically connectable to a power supply, the inductive coil assembly being operative to inductively couple with the inductive power receiver of the inductively powered device and transmit power thereto when the inductively powered device is retained against the face plate by the plurality of magnets in an axially shifted relationship to the inductive coil assembly.

2. The mounting assembly of claim 1 , wherein the face plate has an elastomeric front surface.

3. The mounting assembly of claim 1 , wherein an elastomeric front surface of the face plate comprises silicone rubber.

4. The mounting assembly of claim 1 , wherein the plurality of magnets attached to the mounting plate comprise four neodymium magnets.

5. The mounting assembly of claim 1 , wherein individuals ones of the plurality of magnets attached to the mounting plate are disc magnets.

6. The mounting assembly of claim 5 , wherein the individual ones of the plurality of neodymium magnets have a diameter of 10 mm and a height of 3 mm.

7. The mounting assembly of claim 1 , wherein individual ones of the plurality of magnets have a pull force of at least 1 kg.

8. The mounting assembly of claim 1 , wherein individual ones of the plurality of magnets have a pull force of at least 1.5 kg.

9. The mounting assembly of claim 1 , wherein the plurality of magnets attached to the mounting plate have a collective pull force of at least 4 kg.

10. The mounting assembly of claim 1 , wherein the plurality of magnets attached to the mounting plate have a collective pull force of at least 6 kg.

11. A mounting assembly for an inductively powered device having an inductive power receiver and at least a magnetically receptive portion, the mounting assembly comprising:
a mounting housing comprising an face plate and a back plate;
a mounting support member attached to the back plate of the mounting housing, the mounting support member having an adjustable joint for adjusting the orientation of the mounting housing;
a plurality of magnets contained within the mounting housing for magnetically attracting at least the magnetically receptive portion of the inductively powered device and retaining the inductively powered device against the face plate with the mounting housing being in any orientation relative to the mounting support member; and
an inductive coil assembly within the mounting housing and electrically connectable to a power supply, the inductive coil assembly being operative to inductively couple with the inductive power receiver of the inductively powered device and transmit power thereto when the inductively powered device is retained against the face plate by the plurality of magnets in an axially shifted relationship to the inductive coil assembly.

12. The mounting assembly of claim 11 , wherein the face plate has an elastomeric front surface.

13. The mounting assembly of claim 11 , wherein an elastomeric front surface of the face plate comprises silicone rubber.

14. The mounting assembly of claim 11 , wherein the plurality of magnets attached to the mounting plate comprise four neodymium magnets.

15. The mounting assembly of claim 11 , wherein individual ones of the plurality of magnets attached to the mounting plate are disc magnets.

16. The mounting assembly of claim 11 , wherein the individual ones of the plurality of magnets have a diameter of 10 mm and a height of 3 mm.

17. The mounting assembly of claim 11 , wherein individual ones of the plurality of magnets have a pull force of at least 1 kg.

18. The mounting assembly of claim 11 , wherein individual ones of the plurality of magnets have a pull force of at least 1.5 kg.

19. The mounting assembly of claim 11 , wherein the plurality of magnets attached to the mounting plate have a collective pull force of at least 4 kg.

20. The mounting assembly of claim 11 , wherein the plurality of magnets attached to the mounting plate have a collective pull force of at least 6 kg.
