Abstract

The utility model relates to a Hall angle sensor for a vehicle. Inside a plastic housing there are provided a rotating shaft, a ferromagnetic concentrator ring, a magnet, a return spring, a PCB, a single Hall device, a capacitor, a binding post, a magnetic insulation sheet and an end cap, wherein the Hall device and the capacitor are welded at one end of the PCB and arranged on a central axis formed by the ferromagnetic concentrator ring and the magnet, the other end of the PCB is welded on the binding post, the ferromagnetic concentrator ring and the magnet are arranged on the rotating shaft, and the return spring is used for resetting the rotating shaft. When the rotating shaft drives the magnet on the ferromagnetic concentrator ring to rotate by one angle, the magnetic field of the ferromagnetic concentrator ring rotates by a same angle as that of the ferromagnetic concentrator ring, such a change is detected by the Hall device arranged on the central axis formed by the ferromagnetic concentrator ring and the magnet, and after a signal is processed, the sensor outputs a corresponding voltage. The Hall angle sensor is reasonable in design and simple in magnetic path structure, can provide an excellent linear voltage output within the detection range, and can satisfy the demands of modern vehicles for angle detection.
