An improved rotation angle detecting device that detects a rotation angle of a first member relative to a second member is proposed. The rotation angle detecting device includes a magnet unit fixed to the first member and a pair of magnetic sensors fixed to the second member to provide output signals whose phase is different from each other at 90 degrees in angle. The magnet unit includes a pair of disk plates that has the same magnetic poles at the same circumferential positions and is disposed at a prescribed axial distance and a shaft that is made of magnetic material to support the disk plates at the center thereof. The magnetic unit provides a uniform magnetic field in a space around the shaft between the pair of disk plates, and a pair of magnetic sensors is disposed in the space.

The invention relates to the technical field of shaves, in particular to a floating type shaver. The floating type shaver comprises a head portion, a housing, a main shell, a first floating component and a second floating component, wherein the first floating component is provided with a first through hole, and the second floating component is arranged in the first through hole. A second through hole is formed in the second floating component. A containing groove for containing the first floating component is further formed in the main shell in a sunken manner. A pair of first parent pivot-joint portions are arranged at the left side and the right side of the first floating component. A pair of first son pivot-joint portions matched with the first parent pivot-joint portions are arranged in the containing groove. A clamping component is further fixedly arranged at the bottom of the first floating component. The clamping component is provided with clamping pieces which extend into the front side and the rear side inside the first through hole in a protruding manner. The clamping pieces are provided with a pair of second parent pivot-joint portions. The second floating component is provided with a pair of second son pivot-joint portions matched with the second parent pivot-joint portions. A first elastic sleeving component is mounted between the first floating component and the containing groove, and a second elastic sleeving component is mounted between the second floating component and the housing. According to the floating type shaver, by means of the double son pivot-joint portions, the double parent pivot-joint portions and the double elastic sleeving components, 360-degree rotation can be achieved; and the effect achieved when the shaver is attached to the face in a floating manner is good.

A rotation angle detecting device includes a signal generator, a magnetic rotor and a rotation angle calculating unit that calculates a rotation angle θ of the rotor based on the output signals of the signal generator. The signal generator includes a magnetic rotor that has a permanent magnet and a shaft connectable with the rotating object and at least three magnetic sensor elements disposed in the magnetic field to generate a plurality of output signals when the rotor rotates. The rotation angle calculating unit calculates a first candidate of the rotation angle θ from a first pair of the three output signals, examines whether the first candidate of the rotation angle θ is normal or not and calculates a next candidate of the rotation angle θ from another pair of the three output signals if the first candidate of the rotation angle θ is not normal, examines whether the next candidate of the rotation angle θ is normal or not, repeats the above two steps until a next candidate of the rotation angle θ is judged normal, and outputs one of the first and next candidates of the rotation angle θ as a formal rotation angle if it is judged normal.

A rotating mechanism for an electronic device has a stationary seat with a limiting recess, a limiting ring mounted through the stationary seat with inner and outer limits, a shaft mounted through the stationary seat and the limiting ring with a limiting protrusion. With the limiting protrusion pushing the inner limit and the outer limit sliding in the limiting recess, the shaft achieves two stages of rotation to enhance the rotating angle in both directions. Moreover, with the adjusting of the sizes of the components, the rotating mechanism may provide rotating angle by 360 to 700 degrees.
