Hinge assembly for a wireless charger
First Claim
1. A hinge assembly for a wireless charging device, the hinge assembly comprising:
- a pin block having a pin receiving groove formed at an upper surface and first and second footings spaced apart from each other on opposite sides of the pin block, each footing including a shelf and a seat elevated with respect to the shelf;
a first friction beam attached to the seat of the first footing and extending over the shelf of the first footing;
a second friction beam attached to the seat of the second footing and extending over the shelf of the second footing;
a rotatable pin disposed within the pin receiving groove, the rotatable pin having first and second opposing ends with the first end extending over the first friction beam and the second end extending over the the second friction beam;
a first tensioner operatively coupled between the first friction beam and the shelf of the first footing to press the first friction beam against the first end of the rotatable pin;
a second tensioner operatively coupled between the second friction beam and the shelf of the second footing to press the second friction beam against the second end of the rotatable pin; and
a stem coupled to the rotatable pin between the first and second footings such that the stem rotates with the rotatable pin.

Abstract
A wireless charger for an electronic device. The charger includes a base having a base opening and an interior cavity defined by an upper shell, a lower shell and an inner sidewall extending between the upper and lower shells to define the base opening. An aperture is formed through the inner sidewall between the interior cavity and the base opening and a hinge is connected to the base within the interior cavity and extends through the aperture. The charger further includes a wireless charging assembly that is pivotably attached to the base by the hinge and moveable between a down position in which the wireless charging assembly is disposed within the base opening and an up position in which the wireless charging assembly extends outside the base. The charging assembly has a charging surface and a power transmitting unit disposed adjacent to the charging surface where the power transmitting unit is configured to wirelessly transmit power across the charging surface to a power receiving unit of a portable electronic device.
