摘要： A bicycle speed sensor is provided on a bicycle (1). The bicycle (1) includes a chain stay (2), a rear wheel (3), a brake disk (4) and a positioning member (5). The rear wheel (3) includes a hub (3a) and the brake disk (4) includes a center hole (4a) disposed for the hub (3a) to pass through. The positioning member (5) passes through the chain stay (2), the center hole (4a) and the hub (3a) so that the rear wheel (3) and the brake disk (4) are positioned on the chain stay (2). The bicycle speed sensor includes a signal transmitter (10) and a signal sensor (20). The signal transmitter (10) is configured to transmit a signal and disposed on the brake disk (4). The signal sensor (20) receives the signal from the signal transmitter (10) and is disposed on the chain stay (2). By fixedly positioning the signal transmitter (10) and the signal sensor (20) at the brake disk and a default position of and the chain stay respectively, displacements of sensor components is prevented to provide reliable sensing data.

摘要： A non-contact type torque and angle of rotation sensing device (10) consisting of a magnetic member (30), sensing members (40) and a computing unit (60) for measuring a torque being applied to rotate a transmission member (20) and the angle of rotation of said transmission member (20) in a first axial direction (22) is disclosed. The magnetic member (30) defines a first center (34), and is mounted on and rotatable with the transmission member (20). The magnetic member (30) deflects relative to the transmission member (20) in a nonparallel manner relative to the first axial direction (22) when rotating with the transmission member (20). Sensing members (40) induce a magnetic field variation to output respective electrical signals that exhibit a phase difference there between. The computing unit (60) receives and calculates the electrical signals of the sensing member (40) to obtain the amplitude and to further translate the amplitude into torque value and angle of rotation.

摘要： Provided by the present invention is a device for detecting vehicle operation parameters. A casing deforms due to a force, which changes the magnetic permeability of a magnetic material on the casing. A coil induces the generation of corresponding induced electromotive force, and a corresponding torque value may be obtained by analysis. The magnetic flux density distribution on the surface of a magnetic ring in a region of the same polarity has the characteristic of a part being a strictly increasing or decreasing function, so that a first or second Hall sensor outputs a corresponding analog voltage value which may correspond to the position angle value of a central axis. The magnetic ring may be driven by the rotation of the central axis, so that the magnetic flux density distribution in space changes, and the voltage outputted by the first or second Hall sensors changes correspondingly. The position angle value or the rotation angle value of the central axis may be obtained by analysis, and the rotation speed value of the central axis may be obtained by taking the change value of the central axis with time. With the present invention, accurate vehicle operation parameters may be fed back, thereby improving the riding experience.
