Embodiment Construction

[0041] Such as Figure 1 to Figure 6 As shown, according to a preferred embodiment of the present invention, a double-magnet-ring back-pedal assist interruption system 10 for an electric power-assisted bicycle is mainly composed of a microcomputer 11, a motor 21, a large chainring 31, and a crankshaft 41. , a driving ring 51, two magnetic units 61 and two magnetic sensors 71, wherein:

[0042] The microcomputer 11 has a relative rotation comparison table 12 . Its contents are shown in Table 1 below.

[0043] Table 1

[0044]

[0045] The motor 21 is electrically connected to the microcomputer 11 through a motor driver 22 , so that the microcomputer 11 controls the motor 21 through the motor driver 22 .

[0046] The large toothed plate 31 is fixed on a sleeve 32, and the sleeve 32 is connected to the motor 21 in a one-way rotation, and can be driven by the motor 21 when it is rotating forward. The sleeve 32 idles. In this embodiment, the sleeve 32 is connected to the mo...

Abstract

The invention provides a double-magnetic-ring back-treading boosted interruption system of an electric power assisted bicycle. The double-magnetic-ring back-treading boosted interruption system of the electric power assisted bicycle comprises a microcomputer provided with a relatively-rotating comparison table, a motor, a large gear disc fixedly arranged on a sleeve, a crank shaft rotatably penetrating the sleeve, a driving ring fixed on the crank shaft in a sleeved mode, two magnetic units and two magnetic sensors, wherein the sleeve can be rotatably connected to the motor in a one-way mode, a delay mechanism is arranged between the driving ring and the sleeve, and the driving ring reversely rotates relative to the sleeve. When a reverse rotating angle is larger than or equal to a second angle, the microcomputer controls the motor to perform reverse rotation at first rotation speed and interrupts assisted power. The second angle is smaller than a first angle.

Description

technical field [0001] The invention relates to electric power-assisted bicycles, in particular to an electric power-assisted bicycle double-magnetic-ring back-pedal power-assist interruption system. Background technique [0002] Existing electric power-assisted bicycles have the design of a rear pedal brake, for example, PCT Patent No. WO2012035682A, which discloses a rear pedal-type power-assisted motor control device. It uses anti-pedaling to brake; this case also cooperates with a control device to control the motor to generate regenerative braking, motor braking or motor stop when the anti-pedal brake is applied. Therefore, it discloses foot braking and motor braking. Technology. [0003] in the aforementioned case Figure 6 A and Figure 6 B shows a buffer device arranged between the crank shaft and the chainring, which is composed of the elements of figure numbers 51 and 52, which can provide a buffer space 51c when stepping back, and allow the control device to cut ...
