Therefore, the above is an introduction to the components and assembly methods of a self-generating treadmill 100 with emergency brake provided by a preferred embodiment of the present invention. The following is an introduction to the use characteristics: When a user uses the present invention, he first stands on the looping running belt 32 with both feet, then touches the power generation option on the display and control unit 70 with his fingers, and then the user can run on the looping running belt 32 to drive the looping running belt 32 to move in a loop and simultaneously drive the roller 3 1 rotates, so that the pulley 331 and the belt 332 of the power transmission unit 33 driven by the roller 31 rotate synchronously, and the rotational power is input into the generator 20, so that the generator 20 generates electricity, and the electricity is transmitted to the battery 50 through the controller 40 for storage. At the same time, the power of the battery 50 is simultaneously provided to the controller 40 and the display and control unit 70 for the power required for the operation, so as to achieve the effect of self-generation without consuming additional power.

The display and control unit 70 of the present invention has a plurality of power generation options for the user to choose from. The power generated will increase or decrease as the generator speed is high or low, and the higher the power generated by the generator, the greater the resistance of the generator itself, that is, it takes more power to make the generator reach the power. Therefore, the present invention uses this characteristic of the generator to allow the user to change the resistance effect transmitted from the generator 20 to the circulating running belt 32 while controlling the power generation option.

In addition, through precise control, the user can determine the current power generation (that is, resistance) when the generator 20 has a sufficient rotation speed. For example, if the user wants a higher resistance value, the power generation can be set to 48W, and the controller 40 will allow the generator 20 to reach the maximum power generation. If the user wants to run easily (lower resistance value), the power generation can be set to 12W, and the controller 40 will allow the generator 20 to reach the minimum power generation. That is, the user can select the options of the display and control unit 70 to allow the controller 40 to control the generator 20 to determine the power generation and resistance value.

Of course, when the user sets the power generation of the generator to be between the maximum power generation and the minimum power generation, the control circuit 42 will switch the matrix switch 41 to the power generation mode (as shown in the sixth figure) to increase the torque of the generator 20, thereby increasing the resistance of the looping running belt 32, so as to achieve the effect of self-generation, which is more suitable for experienced users. When the user selects the no-load mode or sets the power generation to zero or close to zero through the options of the display and control unit 70, the control circuit 42 will switch the matrix switch 41 to the no-load mode (as shown in the seventh figure) to minimize the torque of the generator 20, thereby minimizing the resistance of the looping running belt 32, so that the user can run most easily, which is very suitable for beginners.

In addition, no matter whether a novice or an experienced user, when there is a temporary situation or other factors that require the looping running belt 32 to be stopped immediately, the user can immediately press the brake button 80, so that the brake button 80 directly drives the matrix switch 41 of the controller 40 to switch to the brake mode (as shown in Figure 8), so that the torque of the generator at this time reaches the maximum, and then the resistance of the looping running belt 32 also reaches the maximum, so as to achieve the maximum braking effect.

Secondly, the power stored in the battery 50 can be used by the controller 40 and the display and control unit 70, and can also be output to other loads to enhance the function of the present invention.

Thus, the present invention can control the power generation of the generator to achieve the effect of determining the resistance value without adding too much equipment, thereby reducing parts, lowering manufacturing costs, and simplifying operation and maintenance.

The above disclosure is only a preferred embodiment provided by the present invention and is not intended to limit the scope of implementation of the present invention. All equivalent changes made by those with ordinary knowledge in the technical field based on the present invention should fall within the scope of the present invention.
