Abstract

The invention relates to an electronic induction winding device used for winding a safety belt. The electronic induction winding device comprises a frame, a winding shaft, a first induction module, an electromagnetic switch and a control module, wherein the frame is used for containing the safety belt; the winding shaft is used for winding the safety belt and arranged in the frame, and one end of the winding shaft stretches out of the frame; the first induction module is used for inducing an angle signal and / or an acceleration signal of the frame; the electromagnetic switch is used for controlling the rotation and locking of the winding shaft; and the control module is in communication connection with the first induction module and the electromagnetic switch and is used for controlling the electromagnetic switch according to the angle signal or acceleration signal induced by the first induction module. The electronic induction winding device is low in noise, accurate in control and low in cost and can be locked in time.

Description

technical field [0001] The invention relates to the field of automobile manufacturing, in particular to a retractor for safety belts. Background technique [0002] The safety of passengers has always been one of the main goals pursued by the automobile manufacturing industry. In order to ensure the safety of passengers, seat belts are usually equipped on the seats. Traditional seat belt retractors generally use mechanical parts to sense the movement of the seat belt, the movement of the car, and the angle of the car through gravity or inertia, that is, the sense of belt, car and corner, so it is often noisy. At the same time, due to the processing accuracy of the mechanical parts, the induction fluctuations of the movement of the seat belt, the movement of the car and the angle of the car will be relatively large, so the control is difficult. In addition, because the mechanical movement takes time, it will cause the seat belt locking to lag behind. [0003] At the same ti...
