Resistance-adjustable self-power-generating treadmill

Abstract

A resistance-adjustable self-power-generating treadmill includes a chassis; a power generator; a belt driving device including two rollers, a circulating running belt, and a power transmission unit; a controller electrically connected with the power generator; a battery electrically connected with the controller; a handlebar; and display and control unit, which is mounted on the handlebar to allow a user to watch messages and to control, through touching the display and control unit, the controller to adjust the power generation amount of the power generator. Through adjusting the power generation amount of the power generator, the resisting force that is applied from the power generator to the circulating running belt is also controllable.

I claim: 
     
         1 . A resistance-adjustable self-power-generating treadmill, comprising:
 a chassis;   a power generator, which is mounted on the chassis to convert input power into electrical power for outputting;   a belt driving device, which comprises two rollers, a circulating running belt, and a power transmission unit, wherein the two rollers are rotatably mounted on the chassis, and the circulating running belt is looped around the two rollers and is adapted to be acted upon by an external force to move, in a circulating manner, in order to drive the rollers to rotate, and the power transmission unit is coupled between one of the rollers and the power generator to transfer rotating power of the rollers to the power generator;   a controller, which is mounted on the chassis and is electrically connected with the power generator to have electrical power generated by the power generator fed into the controller, the controller being operable to control a power generation amount of the power generator, wherein the control of the power generation amount of the power generator by the controller is achieved by directly setting a power of the power generator between a maximum power generation amount and a minimum power generation amount of the power generator in order to set a resistance level of the circulating running belt;   a battery, which is mounted on the chassis and is electrically connected with the controller so that the controller transmits the electrical power generated by the power generator into the battery to have the electrical power accumulated and stored in the battery and to allow the battery to supply electrical power for operation of the controller;   a handlebar, which connected, in an erected manner, on the chassis; and   a display and control unit, which is mounted on the handlebar and adapted to allow a user to watch messages and to control, through touching the display and control unit, the controller to adjust the power generation amount of the power generator, so that through adjusting the power generation amount of the power generator, the resistance level that is applied from the power generator to the circulating running belt is controlled, wherein the controller is operable to directly set the power of the power generator to set the resistance level of the circulating running belt.   
     
     
         2 . The resistance-adjustable self-power-generating treadmill according to  claim 1 , wherein the two rollers are spaced from each other by a distance. 
     
     
         3 . The resistance-adjustable self-power-generating treadmill according to  claim 1 , wherein the circulating running belt comprises an annular band. 
     
     
         4 . The resistance-adjustable self-power-generating treadmill according to  claim 1 , wherein the power transmission unit comprises a pulley and a belt, the pulley being coaxially connected with the one of the rollers, the belt being connected between the pulley and an input axle of the power generator. 
     
     
         5 . The resistance-adjustable self-power-generating treadmill according to  claim 1 , wherein the display and control unit comprises a touch screen.
