Kart

Abstract

A kart having a pedal speed controller and other components and arrangements thereof are disclosed. The kart can be provided with a controller for controlling speed; the pedal speed controller comprising a pedestal and a pedal, one end of the pedal is articulated with the pedestal and keeps a certain angle with the pedestal. The pedal speed controller also comprises a sensor connected with the controller, and the sensor can obtain displacement signal along the tread direction of the pedal. The pedal speed controller has the advantages of realizing pedal control of acceleration or deceleration for drivers, avoiding interference with manual adjustment of kart direction, preventing from mutual influence between speed regulation and steering, improving the speed control performance of the kart, and improving the driving experience.

What is claimed is:

 a frame;   a baseplate supported by the frame;   a seat supported by the frame;   a front fork rotatably supported by the frame;   a front wheel rotatably supported by the front fork;   a motor operably coupled to the front wheel so that it can drive the front wheel;   a controller operably coupled to the motor and configured to control a speed of the kart, the controller comprising:
 a pedestal; 
 a pedal, wherein one end of the pedal is articulated with respect to the pedestal and the pedal maintains a certain angle with respect to the pedestal; and 
 a sensor connected to the controller, the sensor configured to determine a displacement signal of the pedal; 
   wherein the controller controls the speed of the kart based on the displacement signal detected by the sensor.   
     
     
         2 . The kart of  claim 1 , further comprising a battery configured to power the kart, wherein the battery is supported by the baseplate adjacent the front wheel and forward of the seat, and the controller is supported by the frame facing a rider on the kart. 
     
     
         3 . The kart of  claim 2 , wherein the front fork is arranged along a longitudinal axis of the frame, and the battery is supported by the baseplate and positioned on the longitudinal axis of the frame. 
     
     
         4 . The kart of  claim 3 , further comprising a shell configured to cover a top portion of the frame and enclose at least a portion of the battery, the controller, and the front fork. 
     
     
         5 . The kart of  claim 2 , further comprising a positioning structure configured to attach the battery to the baseplate, the positioning structure comprising a lock piece, a lock hook and a nut, wherein the lock piece comprises a transverse segment configured to attach to an upper surface of the battery, a lateral segment positioned at a lateral side of the battery, and a transverse permanent seat attached to the baseplate, the transverse segment including a plughole such that one end of a lock hook can be inserted into the plughole and fixed to the transverse segment of the lock piece by the nut. 
     
     
         6 . The kart of  claim 5 , wherein the baseplate further comprises an installation slot and the battery is locked by the lock piece inside the installation slot. 
     
     
         7 . The kart of  claim 1 , wherein the baseplate or frame supports at least one anti-sway pillar to prevent the kart from tipping to either side. 
     
     
         8 . A retention device for a kart battery, comprising:
 a bracket comprising a transverse section that can apply a force to a surface of the battery, the bracket further comprising a lateral section that is coupled to the base plate of the kart, wherein the transverse section comprises a socket;   a locking hook and a nut, the locking hook comprising a hook that engages a hook portion on a base plate of the kart, the locking hook further comprising an end that is inserted into the socket of the bracket and fixed to the transverse section by the nut.   
     
     
         9 . The retention device of  claim 8 , further comprising at least one bolt such that the bracket is fixed to the base plate by the bolt passing through the lateral section of the bracket. 
     
     
         10 . The retention device of  claim 9 , wherein the nut is a wing nut. 
     
     
         11 . A kart comprising:
 a base plate and a gantry connected to the base plate;   a front fork steering assembly mounted on the gantry; and   a battery configured to power the kart, the battery mounted on the base plate via a positioning means, wherein the positioning means comprises a retention device comprising a bracket comprising:
 a transverse section that can apply a force to a surface of the battery; 
 a lateral section that is coupled to the base plate of the kart, wherein the transverse section comprises a socket; 
 a locking hook and a nut, the locking hook comprising a hook that engages a hook portion on a base plate of the kart, the locking hook further comprising an end that is inserted into the socket of the bracket and fixed to the transverse section by the nut; and 
   wherein the base plate further comprises a hook body bore that receives a portion of the locking hook after the locking hook is inserted into a shift hole and shifted toward the hook body bore and wherein the hook portion of the locking hook engages the base plate of the kart between the shift hole and the hook hole and wherein the base plate further comprises a mounting groove such that the bracket retains the battery in the mounting groove.   
     
     
         12 . A kart comprising:
 a body comprising a floor or base plate and a gantry located at the front end of the body;   a front fork steering assembly supported by the gantry, wherein a front drive wheel is supported by the front fork steering assembly;   at least one anti-roll column connected to the base plate and having a lower end spaced a clearance distance from the ground;   a motor supported by the front fork steering assembly and configured to drive the front drive wheel; and   a battery configured to provide power to the motor, the battery being positioned adjacent to and rearward of the front drive wheel.   
     
     
         13 . The kart as claimed in  claim 12 , wherein the anti-roll column is attached directly to the base plate. 
     
     
         14 . The kart as claimed in  claim 12 , wherein the anti-roll column is located rearward of a forward edge of the front drive wheel.
