Scooter

Abstract

The invention provides a scooter which presses a pedal by the gravity of human body, thus pulling the wheel to rotate by a pulling cable or a chain. The scooter comprises a bracket (2), a front wheel (1), a rear wheel (3), a pedal (4), a transmission chain or rope (6), a supporting guide pulley (5), a unidirectional transmission mechanism (7), a recovery spring (8) and a supporting guide pulley bracket (9), etc. The working principle of the scooter is that when the pedal (4) is forcibly treaded, the force is transmitted to the unidirectional transmission mechanism (7) by the transmission chain or rope (6) which is connected with the end of the pedal and drives the rear wheel (3) to roll forwards; meanwhile, the recovery spring (8), one end of which is connected with the transmission chain or the rope (6), is stretched and the energy is stored. When a foot which treads the pedal (4) uplifts, the elastic energy stored in the recovery spring (8) is released and pulls the transmission chain or the rope (6) to lead the pedal (4) to raise when the advancing of the wheel is not obviously affected as the unidirectional transmission mechanism (7) is reversely rotated and has small force generated by the wheel. As the scooter adopts a treading type to drive the scooter to move forwards, the scooter can be used for traffic and exercising the leg muscle and gaining good exercise and entertainment effects at the same time; secondly, the scooter adopts a simple type that the pedal pulls the transmission device to drive the wheel to move forwards, has small volume and is convenient for being folded and carried.

Description

technical field [0001] The invention relates to a scooter that walks by human body weight, in particular to a scooter that uses a pedal to drive a cable / chain to pull wheels to rotate. Background technique [0002] Existing two or three-wheeled scooter mainly rely on a person's pedal to obtain power and then use inertia to walk. It needs to be frequently pedaled with one foot to walk, which is not very convenient, and the gliding speed of the scooter cannot be improved. Documents such as ZL0111859.6, ZL02111047.7, ZL02212242.2, ZL02234418.7, ZL200320105635.5, ZL20042010252.1 and patent applications 200310105597.8, 200510021759.9 and other documents disclose the use of pedals to directly drive the rack and pinion Car device, although these devices can realize the purpose of pressing the pedal with human body weight and pushing the car forward, but the structure is more complex, heavy, and the production process is more complicated.

Problems solved by technology

[0002] Existing two- or three-wheeled scooters mainly rely on a person's pedal to obtain power and then use inertia to walk. They need to use one foot to frequently pedal the ground to walk, which is not very convenient, and the gliding speed of the scooter cannot be improved.

Documents such as ZL0111859.6, ZL02111047.7, ZL02212242.2, ZL02234418.7, ZL200320105635.5, ZL20042010252.1 and patent applications 200310105597.8, 200510021759.9 and other documents disclose the use of pedals to directly drive the rack and pinion Although these devices can achieve the purpose of pressing the pedals with the weight of the human body and pushing the car forward, the structure is relatively complicated and heavy, and the production process is relatively complicated.
