A device and method for detecting an absolute multi-turn rotation angle. The device includes a housing, a cover plate and a rotating shaft. The rotating shaft is fixed with a main gear, which is meshed with driven gears including a large driven gear and a small driven gear. The main gear is externally meshed with the large driven gear. The driven gears are connected with a two-stage speed reduction device which enables the rotating shaft to rotate multiple circles to slow down to a circle-number gear and enables the circle-number gear to rotate one circle only. Both driven gears and the circle-number gear are provided with bearings. The bearings have magnets therein, and the two magnets are relatively fixed with the driven gears and the circle-number gear, respectively. The top edges of the bearings fit with a printed circuit board, angle sensing chips which are fixed on the printed circuit.

Example embodiments relate to a vehicle energy absorbing device that includes a primary energy absorbing box and a secondary energy absorbing box, the primary energy absorbing box having a U-shaped cross section with a bottom and a wall extending therefrom, the secondary energy absorbing box being nested inside the primary energy absorbing box. In the event of a collision between a car and a pedestrian, the secondary energy absorbing box of the vehicle energy absorbing device is configured to provide continuous stiffness when the primary energy absorbing box is almost collapsed, so as to protect lower legs of pedestrians and reduce harm thereto. The vehicle energy absorbing device can not only decrease harm to lower legs of pedestrians, but also reduce damage to automobiles as a result of a low-speed collision.
