Problems solved by technology

If an external derailleur is used, due to the large torque output by the mid-mounted motor, the pulling force of the chain is very large, and there will be a lot of shifting noise during the shifting process.
If an internal derailleur is used, the internal derailleur may be damaged due to excessive chain tension if shifting while riding
At present, in the electric bicycle industry, there is no mature solution to the problem of excessive chain tension during the shifting process

Abstract

The invention discloses a detection mechanism of a speed change mechanism of an electric bicycle. Magnets are adsorbed on a speed changer pull line, so that the magnets and the speed changer pull line synchronously move; linear Hall sensors detect the change of displacement of the speed changer pull line so as to induce the working state of a speed changer. The invention further discloses a speed changing method of the electric bicycle. When the linear Hall sensors induce a speed changing process, the linear Hall sensors transmit speed-change generating signals to a controller, so that the output power of a middle-mounted motor of the electric bicycle is reduced, and the tensile force of a chain is decreased; when the speed changing process is completed, the output power of the motor is recovered. The tensile force of the chain is reduced, so that the problem that during changing speed, an external speed changer generates too large noise or an internal speed changer is damaged is solved.

Description

technical field [0001] The invention relates to the technical field of electric bicycles, in particular to a detection mechanism for a speed change mechanism of an electric bicycle capable of automatically detecting the action of a speed change mechanism and a speed change method for an electric bicycle. Background technique [0002] The mid-drive system in the field of electric bicycles is becoming more and more mature, and its market share is gradually increasing. With the increase in the number of mid-drive systems, the problem of excessive chain tension in the rear derailleur brought about by its transmission structure becomes more and more prominent. If an external transmission is used, since the output torque of the central motor is large, the pulling force of the chain is very large, and there will be a lot of noise during the shifting process. If an internal derailleur is used, the internal derailleur may be damaged due to excessive chain tension if shifting while r...
