Problems solved by technology

[0002] Currently commercially available roller skates, skateboards and scooters are usually formed by directly installing shoe wheels on the soles or pedals. A recreational sport tool
Chinese patent No.86104869 discloses a kind of gravity conversion drive roller skates, the conversion of its human body gravity into traction is to directly adopt the gear lever mechanical transmission to realize. Only non-horizontal downward movement can be used, resulting in a large momentum when the power device touches the ground, short action time, instability of the human body, and excessive useless branch force, which affects the effective conversion efficiency of human body gravity; moreover, this power device Also because it is all mechanical transmission, its force adjustment function and force unloading function are not ideal

Embodiment Construction

[0042] The self-propelled power drive device of the present invention is composed of a bracket system composed of an upper bracket 1 and a lower bracket 2 that can be combined with a pedal or a shoe sole, a hydraulic pressure conversion mechanism fixed on the lower bracket 2, and a variable speed rotation mechanism. The power output member 24 is then in drive connection with the power wheel 48 connected to the lower bracket 2 .

[0043] The upper brackets of the device can be 1-8 (the corresponding pedals are 1-8), and each upper bracket 1 has a group of hydraulic pressure conversion mechanisms corresponding to each group of hydraulic pressure conversion mechanisms. The structure shown in Fig. 1, the upper bracket 1 can adopt a concave beam structure (see Fig. 2), the lower bracket 2 can adopt a square beam structure (see Fig. 3), and its hydraulic pressure conversion mechanism is composed of a cylinder group composed of four hydraulic cylinders 3 ( A cylinder group composed o...

Abstract

A self-running power drive unit able to be combined with shoe sole, skate board, skate scooter, toboggan, etc is composed of a frame system consisting of upper and lower frames, a hydraulic force converting mechanism for converting the dead weight and pedaling force of human body to hydraulic force, a speed-varying rotation mechanism for converting the hydraulic force of hydraulic oil tube to rotation torque, and power wheel linked to the power output shaft of said speed-varying rotation mechanism.

Description

Technical field [0001] The invention relates to a self-propelled power drive device, in particular to a device for roller skates, skateboards, scooters, three-wheeled or four-wheeled vehicles, which converts human body weight or pedaling force into power wheel rotation power through hydraulic pressure, gears and other conversion mechanisms. power drive. Background technique [0002] Currently commercially available roller skates, skateboards and scooters are usually formed by directly installing shoe wheels on the soles or pedals. A recreational sports tool. Chinese patent No.86104869 discloses a kind of gravity conversion drive roller skates, the conversion of its human body gravity into traction is to directly adopt the gear lever mechanical transmission to realize. Only non-horizontal downward movement can be used, resulting in a large momentum when the power device touches the ground, short action time, instability of the human body, and excessive useless branch force,...
