Description

Device for increasing pedaling feeling of bottom bracket of electric power-assisted bicycle

This creation is about a device for increasing the pedaling feeling on the bottom bracket of an electric-assisted bicycle, especially a device that can be installed on the original bottom bracket of the electric-assisted bicycle to effectively improve the feeling of pedaling during riding, and has the effect of saving costs. The bottom bracket of the electric-assisted bicycle increases the pedal feeling device.

The sensors of conventional electric bicycles can be roughly divided into speed sensors and torque sensors.

In terms of speed sensor, it is composed of a sensing contact point and a set of discs containing many magnets. When stepping on the discs to rotate with the crank, each magnet will generate frequency signals through the sensing contact points, and Transmit the frequency signal to the controller. However, this method cannot determine the difference in pedaling force caused by the gradient change. It is necessary to compare the motor speed and pedaling frequency to compensate. When the power is insufficient, there will be a drag feeling similar to that of a gear brake; on the contrary, if the power is too large, it will produce a feeling of stepping on the air, which will affect the feeling of riding.

For the torque sensor, the built-in strain gauge is deformed by the pedaling pressure, and the strain is converted into a signal linearly related to the torque by using the principle of resistance strain, which is transmitted to the controller. Although this method has delicate sensing and timely feedback, it is more accurate to grasp the riding situation, and is appropriately driven by a motor according to the torque change, and the overall pedaling feeling is more natural, but the cost is relatively low. More expensive.
