Problems solved by technology

[0003] At present, electric bicycles in China are mainly pure electric vehicles, while electric bicycles are mainly used in European and American countries. Various domestic electric vehicle manufacturers and colleges and universities are also researching smart electric bicycles to open up export channels, but it is far from being truly intelligent. There is still a long way to go before commercialization. On the one hand, it is poor in versatility, and on the other hand, it is too expensive.

Embodiment

[0018] Embodiment: As shown in Fig. 1 and Fig. 2, an electric bicycle torque sensing device includes a bottom bracket 1 and a crankshaft 2, and a turntable 3 is relatively fixed on the crankshaft 2, and the turntable 3 is arranged between the crankshaft 2 and the bottom bracket. 1, on the inner side of the turntable 3, there is a circle of convex teeth 4 that protrude axially and are arranged at intervals. The bottom bracket 1 is fixed with a case 5, which is set outside the turntable 3, and A circuit board 9 is provided, and two L-shaped mounting plates 10 are fixed on the cover 5. An open groove 11 is arranged on one side of the L-shaped mounting plate 10 perpendicular to the tooth plate 2, and an iron core 6 is fixed in the open groove 11. The core 6 is arranged radially and is located outside the circumference of the protruding tooth 4. A coil 7 is wound on the iron core 6. The coil 7 communicates with the control circuit on the circuit board 9. The end of the iron core 6 a...

Abstract

The torque sensor for electric bicycle includes a five-way tube and a toothed wheel, as well as a turntable with raised teeth and fixed to the toothed wheel, two iron cores with wound coil fixed to the bicycle frame a steel magnet. The coils can send electric signal proportional directly to the bicycle speed to the control circuit, so that the control circuit controls the output power based on to the electric signal so as to reach the speed regulating and boosting effect.

Description

technical field [0001] The invention relates to a torque sensor device for an electric bicycle. Background technique [0002] In recent years, electric bicycles have gradually been accepted by consumers as an environmentally friendly and energy-saving means of transportation. Whether at home or abroad, the sales of electric bicycles in the world are also increasing year by year, and the trend of electric bicycles replacing bicycles is gradually expanding. . [0003] At present, electric bicycles in China are mainly pure electric vehicles, while electric bicycles are mainly used in European and American countries. Various domestic electric vehicle manufacturers and colleges and universities are also researching smart electric bicycles to open up export channels, but it is far from being truly intelligent. , There is still a long way to go before commercialization. On the one hand, the versatility is poor, and on the other hand, the cost is too high. [0004] The electric bi...
