The locking device of the safety belt retractor comprises a shell, an armature, a spring, a coil, an ECU module and a lock catch signal module, the shell comprises a bottom plate, a vertical arm and a mounting cavity between the bottom plate and the vertical arm, and the armature is pivotally supported above the vertical arm and comprises a first supporting leg extending to the position above the mounting cavity. One end of the spring is fixed to the armature, the other end of the spring is fixed to the shell, the coil is installed in the installation cavity, and a magnetic field generated after electrification can attract the first supporting leg to overcome the traction effect of the spring and move from the locking position to the releasing position. The ECU module is in control connection with the lock catch signal module, and the ECU module controls the initial action time and/or magnitude of current flowing through the coil so as to control the rebound strength of the first supporting leg. The current of the coil is controlled through the ECU module, so that the impact force between the armature and the metal shell can be reduced on the basis of not influencing the quick reset of the armature.
本说明书实施例提供一种安全带卷收器的锁止装置,包括外壳、衔铁、弹簧、线圈、ECU模块和锁扣信号模块,外壳包括底板、立臂和底板与立臂之间的安装空腔,衔铁可枢转地支撑在立臂上方,包括延伸到安装空腔上方第一支腿,弹簧一端固定在衔铁上,另一端固定在外壳上,线圈安装在安装空腔内,通电后产生磁场可吸附第一支腿克服弹簧的牵引作用由锁止位置向释放位置移动;ECU模块控制连接锁扣信号模块,ECU模块控制流过线圈电流的起始作用时间和/或大小,以控制第一支腿的回弹力度。通过ECU模块控制线圈的电流,在不影响衔铁快速复位的基础上,能够降低衔铁与金属壳体的撞击力度。
