Abstract

A cell phone charger comprises a main body having embedded therein a charging circuit configured to receive line AC voltage and to convert it to a DC voltage suitable for charging the mobile device. AC prongs fold into the body in a stowed position and a connection structure formed integrally with the main body grasps onto and holds the charger secured to the cell phone device. In a preferred embodiment, the AC prongs pivot independently and lie flat against an outside surface of the main body.

Claims

1. A mobile device charger, comprising:

a main body having embedded therein a charging circuit configured to receive a line AC voltage and convert it to a DC voltage suitable for charging the mobile device;

AC prongs foldable into the body in a stowed position and configured to be pivoted out of the main body in an operable position;

a connection structure formed integrally with the main body, the connection structure extends from the main body and is configured to grasp onto and hold the charger secured to the mobile device;

a charger plug integrally formed with the charger and located on the charger such as to allow the charger plug to be inserted into a charging port of the mobile device, the charger being so configured as to enable it to be connected physically and electrically to the mobile device during the use of the mobile device and to allow the AC prongs to be positioned in the operable position for charging of the mobile device, while the charger is physically integrated with the mobile device.

2. The charger of claim 1, wherein the main body is a generally flat body with a substantially uniform thickness dimension and having length and width dimensions, with the thickness dimension of the main body being not larger than one quarter of either one of the length or width dimension.

3. The charger of claim 1, wherein the main body is a generally flat body with a substantially uniform thickness dimension and with length and width dimensions, the ratio of the thickness dimension to the product of the length and width dimensions being less than or equal to 0.05.

4. The charger of claim 1, wherein the thickness dimension is less than 12 mm.

5. The charger of claim 1, wherein the connection structure comprises left and right resilient holding panels which extend generally away from a plane in which the main body lies and which are spaced apart and positioned to grasp sidewalls of the mobile device.

6. The charger of claim 5, wherein the side panels have substantial cutouts formed therein in positions that avoid obstructing any electrical connections or switches of the mobile device.

7. The charger of claim 1, wherein the main body has length and width dimensions and the AC prongs are positioned to fold along the width dimension of the main body, in opposite directions.

8. The charger of claim 1, wherein the main body has length and width dimensions and the AC prongs are positioned to fold along the length dimension of the main body, in opposite directions.

9. The charger of claim 1, wherein the main body has length and width dimensions and the AC prongs are positioned to pivot about a common axis and to fold into the main body such that a width dimension of the prongs is fully accommodated in the main body.

10. The charger of claim 1, wherein the AC prongs are configured to be positioned flush with an outer surface of a back side of the main body in the stowed position.

11. The charger circuit of claim 1, wherein the AC prongs are formed with a detent mechanism that maintains the operable position of the prongs.

12. The charger circuit of claim 1, wherein the charging circuit comprises a main power switching device controlled to conduct charge flow periodically based on a duty cycle, said duty cycle being controlled by a control circuit, said main switching device being configured to feed a charge to an inductor/capacitor circuit, at which is developed a DC charging output voltage for a battery of the mobile device.

13. The charger circuit of claim 1, wherein the main body has a width and a thickness dimension which matches a corresponding thickness and with dimensions of the mobile device and wherein the connection structure integrally extends from the main body and has a shape and dimensions which match corresponding shape and dimensions of a cover portion of a mobile device which is removed, allowing the connection structure to connect to the mobile device in the same manner and mimicking the cover of the mobile device.

14. The charger of claim 1, wherein the main body has a rectangular shape with a width and thickness which match a corresponding width and thickness of the mobile device, and which is configured to reside atop of a mobile device with a cage-like structure which fits over the mobile device to hold the charger main body integrally connected to the mobile device, and a dependent ribbon structure connected by a living hinge to the main body and supporting a DC power plug which fits a corresponding DC power charging port of the mobile device.

15. The charger of claim 1, wherein the charger circuit is comprised of circuit components which are generally flat and widely distributed over a space of at least 30 cm square with a thickness which does not exceed 7 mm.

16. The charger of claim 1, further comprising a USB connector coupled to the charger plug.

17. A mobile device charger, comprising:

a clip formed of a first clip body portion and a second body portion which are interconnected via a spring-biased clip and which provide an ability to be clipped to an article of clothing;

a charging circuit embedded in the clip and including AC prongs foldable into the body of the clip in a stowed position and configured to be pivoted out of the body portion in an operable position;

a cell phone hook on which the mobile device can be hooked, the hook having electrodes formed therein which are electrically coupled to the mobile device, whereby the clip provides the dual functionality of supporting mobile device and also enabling it to be inserted into an AC power source to charge the mobile device.

18. The mobile device of claim 17, including the USB connector.

19. The mobile device of claim 17, wherein the charging circuit is embedded in the first body portion and the AC prongs are mounted to the second body portion.

20. The mobile device of claim 17, in combination with a mobile device jacket which is configured to clip and hold onto a mobile device charger and which is provided with said mechanism that allows it to be hooked on the hook of the clip and to communicate the charging signals to the mobile device.
