Magnetically attachable charging devices
Attachment devices that can secure a phone or other electronic device in place in a vehicle or other structure. One example can provide an attachment device that can include a stalk portion to attach to a surface or structure in a vehicle, such as a vent cover, dashboard, monitor, cup holder or other surface or structure. The attachment device can further include an attachment feature to provide for an attachment to the electronic device. Further examples can provide power for a phone or other electronic device.
1. An attachment device comprising:
an enclosure formed by a contacting surface and a back plate;
a magnet array in the enclosure;
a mid-plate;
a stalk attached to the mid-plate, where the mid-plate is attached to the back plate; and
a front enclosure having an opening for the stalk, the front enclosure covering the mid-plate.
2. The attachment device of claim 1 wherein the stalk comprises a grip, where the grip can form a physical connection to a structure to hold the attachment device in place.
3. The attachment device of claim 2 wherein the contacting surface comprises a layer of silicone.
4. The attachment device of claim 3 wherein the grip comprises a layer of silicone.
5. The attachment device of claim 1 further comprising a coil in the enclosure, the coil arranged to transfer power to an electronic device that is attached to the attachment device.
6. The attachment device of claim 5 further comprising near-field communication circuitry and components.
7. The attachment device of claim 6 wherein the near-field communication circuitry and components comprises a tag and a capacitor.
8. An attachment device comprising:
an enclosure;
a magnet array in the enclosure;
an alignment structure separate from the magnet array, where the alignment structure aligns an electronic device to the attachment device in a single orientation; and
a mounting structure to attach to a vehicular surface.
9. The attachment device of claim 8 wherein the alignment structure comprises a magnet.
10. The attachment device of claim 9 further comprising:
a coil in the enclosure, the coil arranged to transfer power to the electronic device.
11. The attachment device of claim 10 wherein the coil is laterally surrounded by the magnet array.
12. The attachment device of claim 11 wherein the magnet array is configured to hold the electronic device adjacent to the attachment device in any one of a number of orientations.
13. The attachment device of claim 12 wherein the magnet array is configured to hold the electronic device adjacent to the attachment device in any rotational orientation.
14. The attachment device of claim 13 wherein the magnet array is configured to move between a first position in the enclosure and a second position in the enclosure, wherein the first position is located between the second position and a contacting surface of the enclosure.
15. The attachment device of claim 14 wherein the contacting surface comprises silicone.
16. An attachment device comprising:
an enclosure having a contacting surface;
a mounting structure comprising a grip to attach to a vehicular surface, where the mounting structure is attached to the enclosure; and
a magnet array in the enclosure wherein the magnet array is configured to move between a first position in the enclosure and a second position in the enclosure, wherein the first position is located between the second position and the contacting surface of the enclosure.
17. The attachment device of claim 16 further comprising a connector receptacle located on the surface of the attachment device.
18. The attachment device of claim 17 further comprising:
an alignment magnet separate from the magnet array, where the alignment magnet aligns an electronic device to the attachment device in a single orientation.
19. The attachment device of claim 18 further comprising near-field communication circuitry and components.
20. The attachment device of claim 19 wherein the near-field communication circuitry and components comprises a tag and a capacitor.
