Problems solved by technology

[0002] The defect of the current automatic shifting solutions on the market is that each type of derailleur must be programmed separately, and after setting, it can only be used one-to-one. The same program cannot be used for different manufacturers and different models on the market. derailleur
Therefore, no matter how many types of derailleurs there are on the market, bicycle manufacturers have to make many programs to match them, which brings a lot of inconvenience to production, after-sales or bicycle DIY enthusiasts.

Abstract

The invention discloses an automatic speed-changing method for a speed change bicycle. The method comprises the following steps: a self-learning step including: adjusting a speed-changing wire to an initial position, when the speed-changing wire is located at the initial position, setting the tap position of a chain-moving device to be 1, recording and saving the initial position by an MCU, when each tap position is changed in a riding simulation process, recording and saving the corresponding position or displacement of the speed-changing wire by the MCU, and ending the self-learning step after all the tap positions are traversed; and a riding step including: when tap position change is needed during a riding process, controlling the tap position change according to the corresponding position or displacement of the speed-changing wire, which is recorded by the MCU when each tap position is changed. The apparatus and method are good in universality and automation, and bring convenience to production, after sale and bicycle DIY fans.

Description

technical field [0001] The invention relates to a speed-changing bicycle, in particular to an automatic speed-changing method and device for a speed-changing bicycle. Background technique [0002] The defect of the current automatic shifting solutions on the market is that each type of derailleur must be programmed separately, and after setting, it can only be used one-to-one. The same program cannot be used for different manufacturers and different models on the market. derailleur. Therefore, no matter how many types of derailleurs there are on the market, bicycle manufacturers will have to do many programs to match them, which brings a lot of inconvenience to production, after-sales or bicycle DIY enthusiasts. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an automatic shifting method and device for a shifting bicycle in view of the deficiencies in the prior art, which realizes gear position preservation and ...
