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 plurality of magnets spaced apart from each other and each attached to a first section of 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; and
an inductive coil assembly attached to a second section of 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 cluster of the plurality of magnets;
wherein the first section of the mounting plate and the second section of the mounting plate defines an offset planar relationship relative to each other along the mounting plate without overlap and in which a planar quadrangular area of the plurality of magnets is spaced apart from a planar quadrangular area of the inductive coil assembly, in a single direction.

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

3. The mounting assembly of claim 2 , wherein the 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 individual 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 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. The mounting assembly of claim 1 , further comprising a mounting support member attached to a rear face of the mounting housing, the mounting support member having an adjustable joint for adjusting an orientation of the mounting housing.

12. A mounting assembly for a device having an inductive power receiver and at least a magnetically receptive portion, the mounting assembly comprising:
a mounting housing comprising a front face and a back face;
a cluster of a plurality of magnets spaced apart from each other in a first section of the mounting housing for magnetically attracting at least the magnetically receptive portion of the device along a magnet cluster center facial axis normal to a mounting housing front face plane and retaining the device against the front face of the mounting housing;
an inductive coil assembly within a second section of 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 device along a coil facial axis normal to the mounting housing front face plane and transmit power thereto when the inductively powered device is retained against the front face by the cluster of the plurality magnets;
wherein the first section of the mounting housing and the second section of the mounting housing defines an offset planar relationship relative to each other along the mounting housing front face plane without overlap, the magnet cluster center facial axis of the one or more magnets being parallel to and offset from the coil facial axis of the inductive coil assembly solely in a single direction.

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

14. The mounting assembly of claim 13 , wherein the elastomeric front surface comprises silicone rubber.

15. The mounting assembly of claim 12 , wherein the cluster of the plurality of magnets in the mounting housing comprise four neodymium magnets.

16. The mounting assembly of claim 12 , wherein individual ones of the cluster of the plurality of magnets are disc magnets.

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

18. The mounting assembly of claim 12 , wherein individual ones of the cluster of the plurality of magnets have a pull force of at least 1 kg.

19. The mounting assembly of claim 12 , wherein the cluster of the plurality of magnets in the mounting housing have a collective pull force of at least 4 kg.

20. The mounting assembly of claim 12 , wherein the cluster of the plurality of magnets in the mounting housing have a collective pull force of at least 6 kg.
