Wireless Charging System and Method for Electronic Device Grip Holder

Abstract

A wireless charging system includes an induction coil to generate a magnetic field attached to a housing that has a hole in a surface to accept a grip. A user inserts a grip attached to an electronic device with a receiver circuit, including a receiver coil, into the hole bringing the receiver coil into contact with the magnetic field generated by the induction coil. The magnetic field induces a current in the receiver coil which is used to charge the electronic device. In certain instances, the housing is secured to another surface by an attached mount. Moreover, in certain instances the electronic device is supported by a portion of the hole's perimeter supporting the grip or a securing mechanism holding the grip inside the hole.

What is claimed is: 
     
         1 . A wireless charging system to charge an electronic device, said system comprising:
 a housing having a first surface element and second surface element affixed together;   an opening defined by said first surface element; and   a transmitter circuit comprising an induction coil wherein said induction coil is affixed to said first surface and disposed adjacent to a portion of the perimeter of said opening,   whereby an attachment protruding from a surface of said electronic device can be inserted through said opening to allow said electronic device to be charged with said induction coil without said attachment degrading the quality of charging.   
     
     
         2 . The wireless charging system of  claim 1 , further comprising a power source connected to said transmitter circuit to electrify said induction coil. 
     
     
         3 . The wireless charging system of  claim 2 , wherein said power source is removably connected to said transmitter circuit. 
     
     
         4 . The wireless charging system of  claim 2 , wherein said transmitter circuit further comprises a controller unit to adjust the magnetic field generated by said induction coil. 
     
     
         5 . The wireless charging system of  claim 1 , wherein said opening has an unbroken perimeter so said opening is fully encircled by said first surface element. 
     
     
         6 . The wireless charging system of  claim 5 , wherein said induction coil is disposed adjacent the entirety of said unbroken perimeter. 
     
     
         7 . The wireless charging system of  claim 1 , wherein the perimeter of said opening has an open segment, so said opening is not fully encircled by said first surface element. 
     
     
         8 . The wireless charging system of  claim 1 , wherein said opening comprises a first section and at least one connected extension section extending away from the perimeter of said first section, said at least one connected extension section forming a slot in said first surface element. 
     
     
         9 . The wireless charging system of  claim 8 , wherein said induction coil is disposed adjacent the perimeter of said at least one connected extension section. 
     
     
         10 . The wireless charging system of  claim 1 , further comprising an additional hollow cylindrical segment affixed to said first surface element so said hollow space within said cylindrical segment is accessible through said opening in said first surface element. 
     
     
         11 . The wireless charging system of  claim 10 , wherein the end of said cylindrical segment opposite the end adjacent said first surface element is affixed to said second surface element. 
     
     
         12 . The wireless charging system of  claim 10 , wherein the end of said cylindrical segment opposite the end adjacent said first surface element is enclosed. 
     
     
         13 . The wireless charging system of  claim 1 , further including a clamping mechanism within said housing between said first and second surface elements. 
     
     
         14 . The wireless charging system of  claim 1 , further comprising an anchor receiver disposed on said second surface element to receive an anchor unit. 
     
     
         15 . The wireless charging system of  claim 14 , further comprising an anchor unit affixed to said anchor receiver to secure said housing.
