Scooter with gradient pedal

Abstract

The invention discloses a scooter with a gradient pedal, which comprises a scooter bracket (1), front and back wheels (2, 3), a power pressure bar (4) movably connected to the upper side of the scooter bracket, a return mechanism (A) of the power pressure bar, and a power transmission mechanism assembly (B) arranged between the power pressure bar (4) and a driving wheel (13) on a wheel shaft. The scooter is mainly characterized in that the upper end of the power pressure bar (4) divides the movable pedal into a limiting end and a labor-saving end; when the movable pedal is positioned at the highest position, the gradient (H) of the movable pedal (7) is between 15 and 45 degrees; and a limiting pull rod (10) is arranged between the front part of the limiting end of the movable pedal and the scooter bracket, and the length of the limiting pull rod is equal to the circular arc radius of a circular arc stroke which is formed by a connecting shaft of the movable pedal and the limiting pull rod moving from the highest point to the lowest point. The scooter is a scooter with two to four wheels, and the stepping mode accords with a standing stepping posture of a human body and is easy to apply force smoothly; besides, the scooter has greater power input capability.

Description

Technical field [0001] The invention relates to a reciprocating pedal scooter, in particular to a single-power or double-power scooter with pedals with a certain inclination. Background technique [0002] Present commercially available two to three-wheel scooter mainly utilizes inertial driving after obtaining power by a pedal of people, and it needs one foot to pedal frequently, which is not very convenient. In the published patent literature, the patent No. ZL01237990.5 discloses a flexible double-scooter vehicle. Although the cable can automatically return to its position during the interaction of the two pedals, the vehicle bracket adopts a raised middle part. The mechanism makes the flexible double pedals higher off the ground, the center of gravity of the human body is unstable when pedaling, and there is a feeling of leaning forward and backward when pedaling, which is not conducive to human pedaling force; patent ZL01135643. It is a bicycle with two-pedal up and dow...

Problems solved by technology

[0002] The two- to three-wheeled scooters currently available in the market mainly rely on one foot to pedal the ground to obtain power and use inertial driving. It needs one foot to frequently pedal the ground, which is not very convenient.

In the published patent literature, the patent No. ZL01237990.5 discloses a flexible double-scooter vehicle. Although the cable can automatically return to its position during the interaction of the two pedals, the vehicle bracket adopts a raised middle part. The mechanism makes the flexible double pedals higher off the ground, the center of gravity of the human body is unstable when pedaling, and there is a feeling of leaning forward and backward when pedaling, which is not conducive to human pedaling force; patent ZL01135643. One-up and one-down interactive bicycles with double pedals, but the chain is completely returned by the spring, one is difficult to install, and the other is that the vibration of the spring can easily lead to detachment

Furthermore, since the habitual distance (i.e. amplitude) of people stepping up and down is about 16cm, the stroke of input power will be limited for this reason, so the scooter of the prior art always inputs power (or kinetic energy) when stepping upright. Insufficient, causing the scooter speed to be too low and unable to go uphill
