Abstract
A brake device has a cam and a switch. The cam is securely attached to the steering bar of the electric scooter. The cam has a circular periphery with a plain portion and a notch. The switch is secured to the body of the electric scooter and is electrically connected to the actuator. The switch has an arm with a distal end abutting either the plain portion or the notch according to whether the scooter is turning or traveling straight. With such a brake device, the scooter will be automatically slowed down when the scooter is turned right or left.
Claims5
A brake device for an electric scooter having a body, at least one front wheel rotatably attached to one end of the body, two rear wheels rotatably attached to the other end of the body, an electric actuator mounted on the body to actuate the rear wheels to rotate and a steering bar rotatably attached to the body to pivotally rotate the at least one front wheel relative to the body, the brake device comprising:
- a cam adapted to be securely attached to the steering bar and having a circular periphery, a notch defined in the periphery of the cam and a plain portion of the periphery of the cam;
- and
- a switch with a button adapted to secured to the body of the electric scooter and adapted to be electrically connected to the actuator, the switch having an arm with a distal end abutting the periphery of the cam,
- whereby the switch will send a signal to the actuator to slow down the actuator when the steering bar is rotated relative to the body and the distal end of the arm escapes from the notch and abuts the plain portion of the periphery of the cam to push the button on the switch.
