Braking system of electric skateboard

Abstract

The invention discloses a braking system of an electric skateboard and belongs to the technical field of braking devices. The braking system comprises a rear wheel and a rear fork, wherein the rear wheel is installed on the rear fork, a connecting base is arranged on the rear fork, a braking plate is arranged on the connecting base and acts on the surface of the rear wheel, a torsional spring is arranged in the connecting base and acts on the braking plate, a plurality of braking rollers are arranged at the bottom of the braking plate, included angles formed by rolling trajectories of the braking rollers and the rolling trajectory of the rear wheel are greater than 0 degree but are smaller than 90 degrees, and an included angle formed by the rolling trajectories of every two adjacent rollers is greater than 0 degree but is smaller than 90 degrees. Abrasion caused by using a frictional brake is avoided, a protection effect is played on parts in the braking system, the service life is prolonged, and the riding safety is improved. In addition, the braking system is simple in structure, low in manufacturing cost and convenient to install and maintain, adopts a treaded braking plate and makes the braking plate in contact with the rear wheel, the braking rollers can brake the rear wheel, the braking flexibility is high, and operation is convenient.

Description

technical field [0001] The invention belongs to the technical field of braking devices, relates to the braking of a scooter, in particular to a braking system of an electric scooter. Background technique [0002] Existing electric scooter generally adopts drum brake or disc brake to brake. The braking system of drum brakes is slow in response and has a complex structure with many parts; disc brakes are prone to lockup, and disc brakes are generally suitable for larger vehicles. For electric scooters that require easy portability and simple structure, drum brakes or disc brakes are not suitable. In view of the above technical problems, in the patent text with the authorized announcement number CN205675175U, the technical solution proposed is that the elastic element, the brake block located between the wheel and the wheel cover along the radial direction of the wheel and a brake block located outside the wheel cover along the radial direction of the wheel The pedal block, t...

AI Technical Summary

Problems solved by technology

[0003] Although the above-mentioned technical solution solves the problems of convenient portability and flexible braking, the braking method is to directly apply frictional braking to the tire tread of the wheel through the brake block low-pressure wheel, which is easy to cause wheel wear and reduce the service life, and after the wheel wears out, the surface resistance becomes smaller, and the effect of friction braking will become worse and worse, or even unable to brake, seriously affecting riding safety
