Abstract

A solar charging umbrella uses solar power to charge electronic devices wirelessly, such as by a wireless or inductive charging port. The umbrella is self-sustained, capable of charging electronic devices in locations away from electrical outlets. The umbrella has a rechargeable battery that is recharged by sunlight. When charged, the umbrella'"'"'s battery can charge devices when sunlight is not available. The umbrella supports simultaneous charging of higher power devices such as tablet computers.

Claims

1. A method comprising:

providing an umbrella comprising a shaft and umbrella shade, wherein the umbrella comprises an open position during which the umbrella shade is extended into a position away from the shaft and a closed position during which the umbrella shade is folded into a position closer to the shaft;

coupling a cap above the umbrella shade to the shaft;

coupling a first strut comprising a first solar panel to the cap via first hinge at the cap;

coupling a second strut comprising a second solar panel to the cap via second hinge at the cap, wherein each strut comprises a sleeve having transparent top surface that allows solar radiation to pass through to a respective solar panel housed by the sleeve;

changing the umbrella from the closed to the open position, wherein the umbrella shade pushes against a bottom of the struts while the umbrella shade is extended, causing the struts to rotate via the first and second strut hinges in a first turn direction, so that an angle between a top of the first strut and a top of the cap increases from a first angle in the closed position to a second angle in the open position, and the second angle is greater than the first angle; and

changing the umbrella from the open to the closed position, wherein the bottom of the struts rest against the umbrella shade while the umbrella is folded, causing the struts to rotate via the first and second strut hinges in a second turn direction, so that the angle between the top of the first strut and the top of the cap decreases from the second angle to the first angle, and the second turn direction is opposite of the first turn direction

coupling a rechargeable battery to a battery charging circuit;

charging the rechargeable battery using the battery charging circuit with solar power received from the first and second solar panels;

enclosing the rechargeable battery and battery charging circuit in a battery housing comprising a hole extending through the housing; and

coupling the battery housing to the umbrella by passing the shaft through the hole of the housing;

coupling the solar panels to at least one wireless charging port of the umbrella, whereby when the a battery-operated device is within or near the wireless charging port, the battery-operated device will be charged wirelessly.

2. The method of claim 1 wherein the wireless charging port is an inductive charging pad.

3. The method of claim 1 comprising:

coupling the solar panels to at least one universal serial bus (USB) port, wherein the wireless charging port is coupled to the universal serial bus port.

4. The method of claim 1 comprising:

coupling the solar panels to at one universal serial bus (USB) port of the umbrella, wherein the universal serial bus port and wireless charging port can be used independently of each other.

5. The method of claim 1 wherein the umbrella comprises a shelf, and the wireless charging port of the umbrella coupled to the shelf, and a marking on the shelf indicates a positioning of the wireless charging port.

6. The method of claim 5 wherein the marking on the shelf comprises a box shape.

7. The method of claim 5 wherein the marking on the shelf comprises a rectangular shape.

8. The method of claim 1 comprising:

at the wireless charging port, generating an alternating magnetic field that can be collected and used by the battery-operated device to charge the device'"'"'s rechargeable battery.

9. The method of claim 5 wherein the wireless charging port is coupled to the rechargeable battery of the umbrella by a wire, and the wireless charging port is integrated into the shelf and the wire is hidden from view.

10. The method of claim 1 wherein the umbrella comprises a shelf, and the wireless charging port of the umbrella coupled to the shelf, and a raised portion on the shelf indicates a positioning of the wireless charging port.

11. The method of claim 1 wherein the umbrella comprises a shelf, and the wireless charging port of the umbrella coupled to the shelf, and a lowered portion on the shelf indicates a positioning of the wireless charging port.

12. The method of claim 1 wherein the umbrella comprises a shelf, and the wireless charging port of the umbrella coupled to the shelf, and a visible loop on the shelf indicates a positioning of the wireless charging port.

13. The method of claim 1 wherein the umbrella comprises a shelf, and the wireless charging port of the umbrella coupled to the shelf, and a raised ridge on the shelf indicates a positioning of the wireless charging port.

14. The method of claim 1 wherein the umbrella comprises a shelf, and the wireless charging port of the umbrella coupled to the shelf, and a textured surface on the shelf indicates a positioning of the wireless charging port.

15. The method of claim 1 wherein the wireless charging port operates according to a Wireless Power Consortium (WPC) wireless charging specification.

16. The method of claim 1 wherein the wireless charging port operates according to a Power Matters Alliance (PMA) specification.

17. The method of claim 1 wherein the wireless charging port operates according to an Alliance for Wireless Power (A4WP) specification.
