Drifting electric scooter

Abstract

The present invention relates to a drifting electric scooter and, more specifically, to a drifting electric scooter, wherein: a sensor unit is installed at a controller and the movement of a scooter is controlled according to the moving direction and angle of the controller, and thus a short control section for acceleration and stopping of a conventional electric scooter is widened, so that the problems, such as abrupt start and abrupt stop, of the conventional electric scooter can be solved; the drifting electric scooter allows riders to more precisely control the speed and enjoy riding such that the riders can easily and safely control acceleration and stopping by simple upward/downward movement of the controller; a human body detection sensor is attached to a handle portion of the controller, and thus the scooter stops to prevent malfunction of the scooter when the controller is separated from a user's hand, so that safety is ensured and thus safe riding is possible; and multiple switches for selecting various riding modes are installed at the controller, so that more pleasant and interesting riding than in conventional scooter riding is possible.

1 . A drifting electric scooter comprising:
 a controller ( 10 ) provided therein with a sensor unit ( 11 ), in which movement of the scooter is controlled according to a pointing direction of the controller ( 10 );   a scooter body ( 20 ) having a pressure sensor ( 21 ) installed at a portion where both feet of a user are placed to determine whether the user gets on the scooter;   a pair of front wheel portions ( 30 ) connected by a scooter truck ( 50 ) formed on one side of a lower surface of the scooter body ( 20 ), in which a direction of the front wheel portions ( 30 ) is changed by a first motor ( 60 ) connected to one side of the front wheel portions ( 30 );   a pair of rear wheel portions ( 40 ) connected by a scooter truck ( 50 ) formed on an opposite side of the lower surface of the scooter body ( 20 ), in which a direction of the rear wheel portions ( 40 ) is changed by the first motor ( 60 ) connected to one side of the rear wheel portions ( 40 );   a second motor ( 70 ) installed inside the pair of rear wheel portions ( 40 ) or inside both wheel portions ( 30  and  40 ) to rotate or stop each of the wheel portions ( 30  and  40 );   a control unit ( 80 ) installed in the scooter body ( 20 ) to receive a signal from the pressure sensor ( 21 ) or the sensor unit ( 11 ) of the controller ( 10 ), in which the control unit ( 80 ) controls the first motor ( 60 ) and the second motor ( 70 ) according to a signal from the sensor unit ( 11 ).   
     
     
         2 . The drifting electric scooter of  claim 1 , wherein, when the controller ( 10 ) is raised or lowered while pointing upward or downward by the sensor unit ( 11 ) installed therein, the scooter moves forward or stops, when a left side of the controller ( 10 ) is rotated while pointing to a left, the scooter is turned to the left, when a right side of the controller ( 10 ) is rotated while pointing to a right, the scooter is turned to the right, an acceleration in a forward movement of the scooter is controlled step by step according to an angle of raising or lowering the controller ( 10 ), a stopping speed of the scooter is adjusted step by step according to an angle of raising or lowering the controller ( 10 ), and a direction change to the left and right of the scooter is adjusted step by step according to an angle of rotating the controller ( 10 ) to the left or right. 
     
     
         3 . The drifting electric scooter of  claim 2 , wherein a plurality of switches are installed in the controller ( 10 ) to select various riding modes,
 a riding mode of a first switch ( 13 ) among the plurality of switches is a drifting mode, in which the front wheel portion ( 30 ) and the rear wheel portion ( 40 ) are operated in different directions so that the scooter is drifted,   a riding mode of a second switch ( 14 ) among the plurality of switches is a sliding mode, in which the front wheel portion ( 30 ) and the rear wheel portion ( 40 ) are operated in a same direction so that the scooter slides,   a riding mode implemented when the first switch ( 13 ) and the second switch ( 14 ) among the plurality of switches are pressed simultaneously is a spinning mode, in which a front portion of the scooter is lifted up and a pair of rear wheel portions ( 40 ) rotate in different directions, so that the scooter rotates in place,   a riding mode of a third switch ( 15 ) among the plurality of switches is a hard drifting mode, in which if the third switch ( 15 ) is pressed while the scooter is turning left or right, the rear wheel portion ( 40 ) stops and the scooter slides in a turning direction of the scooter, resulting in a hard drifting, and   a riding mode of a reverse switch ( 16 ) among the plurality of switches is to rotate the front wheel portion ( 30 ) and the rear wheel portion ( 40 ) in opposite directions such that the scooter moves back   
     
     
         4 . The drifting electric scooter of one of  claims 1  to  3 , wherein a human body detection sensor ( 17 ) is installed on a handle portion ( 12 ) of the controller ( 10 ) so that the scooter is automatically stopped when the controller ( 10 ) is separated from the user. 
     
     
         5 . The drifting electric scooter of  claim 1 , wherein the first motor ( 60 ) is attached to a lower surface of the scooter truck ( 50 ) or the scooter body ( 20 ), or accommodated in the scooter truck ( 50 ) or the scooter body ( 20 ), and a driving bar ( 61 ) connected to a rotation shaft of the first motor ( 60 ) is connected to the pair of front wheel portions ( 30 ) and the pair of rear wheel portions ( 40 ) to change directions of the front wheel portions ( 30 ) and the rear wheel portions ( 40 ) corresponding to a rotation direction of the first motor ( 60 ). 
     
     
         6 . The drifting electric scooter of  claim 1 , further comprising a battery unit ( 90 ) installed on a lower surface of the scooter body ( 20 ) for supplying power to the first motor ( 60 ), the second motor ( 70 ), and the control unit ( 80 ), wherein the battery unit ( 90 ) is rechargeable and detachable.
