Foldable double-chain transmission scooter

Abstract

The invention discloses a foldable double-chain transmission scooter which comprises a front frame, a rear frame and a pedal, wherein the front frame is connected with a left handlebar and a right handlebar through a riser, a connecting sleeve with a built-in compression spring is arranged between the left handlebar and the right handlebar, and the compression spring pushes against the part between the left handlebar and the right handlebar; the front frame and the rear frame are respectively provided with a front wheel and a rear wheel; the left and right sides of a middle axle are respectively connected with a left driving chain wheel and a right driving chain wheel, the left and right sides of the rear wheel are respectively connected with a left driven chain wheel and a right reverse gear meshed with a right driven chain wheel, the left driven chain wheel is connected with the left driving chain wheel in a transmission mode through a left chain, and the right driven chain wheel is connected with the right driving chain wheel in a transmission mode through a right chain; and one-way components are respectively arranged in the left driven chain wheel and the right driven chain wheel. The foldable double-chain transmission scooter disclosed by the invention has the advantages that a transmission part on the scooter is set to be parallel to a rear frame girder, so that the space occupied by the transmission part is reduced; and the handlebars can be folded and unfolded, so that the scooter can be conveniently folded.

Description

technical field [0001] The invention relates to a scooter, more specifically, the invention relates to a foldable double-chain drive scooter. Background technique [0002] Because of the moderate speed, the scooter is easy to learn and easy to operate, and has a brake device (stepping on the rear wheel brake). If it is only for ordinary walking and ordinary entertainment, it is not easy to fall down under normal circumstances, so it is suitable for use by various age groups. The balance system that is developing and perfecting has a good exercise effect. [0003] Existing scooter is usually a vehicle frame, a pair of handlebars, each one of front and rear wheels, adds a braking device. Most users step on the pedal with one foot, and the other foot obtains the propulsion of the scooter by pedaling the ground, because only one foot is trained and the speed of using the scooter is very low, and the impact user experience. [0004] For example, a scooter with a drive provided...
