Battery powered skateboard

Abstract

An electric skateboard has a frame assembly that includes a deck with an opening of the deck to house a battery case mounted to a bottom of the deck. The frame includes a top plate that covers the opening and forms with the battery case an enclosure. A battery pack is positioned in at least partially in the enclosure. Front and a rear trucks are mounted to the bottom of the deck. At least one of the first and front and rear trunks is coupled to first and second wheels mounted on axles of the front and rear trucks. The front truck is mounted on the front end and a rear truck is mounted on rear end of the deck. First and second wheels are powered by one motor with a differential and a shaft coupled to the first and second wheel. The motor is coupled to the shaft to rotate the first and second wheels. The motor is electrically connected to the battery pack through a rear channel. The motor rotates the first and second wheels in the same directions and propels the electric skateboard forward and backward.

         6 . The skateboard of  claim 1 , wherein the plurality of deck fasteners are positioned along a length of the deck to distribute forces along the battery case. 
     
     
         7 . The electric skateboard of  claim 1 , further comprising;
 a handle including a remote controller.   
     
     
         8 . The skateboard of  claim 7 , wherein the remote controller is configured to control the hub motors. 
     
     
         9 . The skateboard of  claim 7 , wherein the handle includes one or more foldable arms that are connectable to the deck for carrying the electric skateboard. 
     
     
         10 . The electric skateboard of  claim 7 , wherein the foldable arms each include a protrusion configured to slide into a groove in the deck for carrying the skateboard. 
     
     
         11 . The electric skateboard in  claim 10 , wherein the deck includes carbon fiber materials. 
     
     
         12 . The electric skateboard in  claim 10 , wherein the deck includes a through opening and a top plate that covers the through opening, the through opening forming at least part of the enclosure. 
     
     
         13 . The electric skateboard of  claim 12 , wherein the top plate includes an opening and a cover that covers the opening, the cover allowing wireless signals to pass through. 
     
     
         14 . The electric skateboard of  claim 10 , further comprising:
 one or more sound exciters attached to the deck.   
     
     
         15 . The electric skateboard of  claim 10 , further comprising:
 two elongated side lights mounted to two sides of the deck and extending approximately to the front end and the rear end of the deck.   
     
     
         16 . The electric skateboard of  claim 15 , wherein, the deck has a length between the front end and the rear end, and the two elongated side lights each are more than half of the length of the deck. 
     
     
         17 . The electric skateboard of  claim 10 , further comprising:
 a remote controller for controlling the at least one motor, wherein the remote controller is connectable to the deck for carrying the electric skateboard.   
     
     
         18 . The electric skateboard of  claim 17 , wherein the remote controller includes a body that has a top edge and two wings extending away from the top edge, configured to be gripped by a rider's hand. 
     
     
         19 . The electric skateboard of  claim 18 , wherein the remote controller further includes two arms and protrusions that are located at ends away from the body, and the protrusions face each other and are configured to slide into grooves in the front end of the deck for carrying the skateboard. 
     
     
         20 . The electric skateboard of  claim 19 , wherein the arms have springs, and configured to open from the wings when deployed and stay inside slots in the wings when folded.
