ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a driving brake assembly of a scooter, and more particularly to a driving brake assembly whose base can be stepped by a single foot of the user to control the driver to drive the wheel to rotate or control the brake pad to stop rotation of the wheel.
2. Description of the Related Prior Art
A conventional scooter in accordance with the prior art comprises a drive mechanism for driving the scooter to move, and a brake mechanism for stopping movement of the scooter. However, the drive mechanism and the brake mechanism are respectively mounted on the frame of the scooter at two different positions, so that the user has to shift his foot between two different positions to tread the drive mechanism for driving the scooter to move, or the brake mechanism for stopping movement of the scooter, thereby affecting the balance of the user's body, so that the user easily falls down, thereby causing danger to the user. In addition, the driver of the conventional scooter is directly in contact with the wheel of the scooter to supply power to rotate the wheel, so that when the scooter is sliding without using the power, the driver is also rested and rotated by the rotating wheel such that the driver is easily worn out during long-term utilization, thereby reducing the lifetime of the driver.
SUMMARY OF THE INVENTION
In accordance with the present invention, there is provided a driving brake assembly of a scooter comprising:
a connecting bracket secured to a rear end of a frame and having two sides each provided with an ear plate for pivoting a wheel;
a base pivotally mounted on the connecting bracket by a shaft, and having a first end formed with a front pedal directed toward the frame, and a second end formed with a rear pedal, a wheel protecting slot defined in the base and located under the rear pedal for receiving the wheel therein, a brake pad formed on the base to pivot with the base to press an outer rim of the wheel;
an elastic member mounted between the base and the connecting bracket;
a driver secured on the base and including a rotatable friction wheel pivoted with the base to press the outer rim of the wheel for driving the wheel to rotate; and
a microswitch mounted on the base and connected to the driver for starting and stopping operation of the driver.
The driver is secured on a first side of the base, and the driving brake assembly further comprises a counterweight mounted on a second side of the base for balancing a weight of the driver.
The elastic member is an inverted L-shaped elastic plate, and has a first end secured on the frame and a second end inserted in the base.
The front pedal of the base defines a locking groove for securing one end of the elastic member.
The brake pad of the base has one side formed with a brake sheet directed toward the wheel to press the outer rim of the wheel.
Further benefits and advantages of the present invention will become apparent after a careful reading of the detailed description with appropriate reference to the accompanying drawings.
