Electric kick scooter

摘要

An electric kick scooter including a scooter body, a drive device and a strain gauge is provided. The scooter body has a foot plate, a steering tube and a rear wheel respectively provided at front and rear ends of the foot plate, and a handle bar and a front wheel respectively provided at top and bottom ends of the steering tube. The drive device has a motor installed in the front wheel or rear wheel, and a battery installed with the scooter body and electrically connected to the motor. The strain gauge is attached to the steering tube or handle bar of the scooter body to sense the strain generated on the steering tube or handle bar when it receives a force. The strain signal of the strain gauge is transmitted to a controller for enabling the controller to control an action of the motor accordingly.

主权项

1. An electric kick scooter, comprising:
a scooter body having a foot plate, a steering tube pivotally installed at a front end of the foot plate, a handle bar connected to a top end of the steering tube, a front wheel rotatably installed at a bottom end of the steering tube and a rear wheel rotatably installed at a rear end of the foot plate; a drive device having a motor installed in one of the front wheel and the rear wheel of the scooter body, and a battery installed with the scooter body and electrically connected to the motor; at least one strain gauge attached to one of the steering tube and the handle bar of the scooter body to sense the strain generated on the one of the steering tube and the handle bar when the one of the steering tube and the handle bar receives a force and then generate and transmit a strain signal; and a controller electrically connected with the motor, the battery and the at least one strain gauge to receive the strain signal from the at least one strain gauge and control an action of the motor based on the strain signal thus received, wherein the controller controls accelerating, decelerating, stopping operation or braking of the motor based on the strain signal, wherein when the strain signal generated by the strain gauge and received by the controller has a value less than a predetermined value, the controller does not control the action of the motor, and wherein the controller maintains the action of the motor when the controller does not receive another strain signal sensed by the at least one strain gauge.
