Document Type and Number:
WIPO Patent Application WO/2024/066262
Kind Code:
A1
Abstract:
A torque and speed sensing device and an electric bicycle. The torque and speed sensing device comprises a middle shaft (100), a connecting member (200), a deformation member (300), a mounting frame (400), a signal processing circuit board (500), a speed sensor (600), a permanent magnet (700), and a torque sensor (800). The outer wall of the middle shaft (100) is provided with a sensing tooth part (110). The deformation member (300) has one end fixedly connected to the middle shaft (100), and the other end fixed to the connecting member (200). The mounting frame (400) is fixedly arranged in a five-way pipe (900) and is sleeved on the periphery of the deformation member (300); the signal processing circuit board (500) is mounted on the mounting frame (400); and the speed sensor (600) is mounted on the signal processing circuit board (500) and is arranged opposite to the sensing tooth part (110). The permanent magnet (700) is mounted on the side of the signal processing circuit board (500) facing away from the speed sensor (600), and the torque sensor (800) is mounted on the mounting frame (400).
