The invention provides a safety belt lock catch. The safety belt lock catch comprises an ejection block, a magnetic induction piece and a switch base assembly. The magnetic induction piece is arranged in the ejection block, so that the magnetic induction piece can synchronously move along with the ejection block. Therefore, mutual induction between the Hall sensor and the spring bolt is changed into mutual induction between the Hall sensor and the magnetic induction piece, the induction distance between the Hall sensor and the spring bolt is shortened, and the induction stability can be improved. Besides, the switch base assembly is arranged on the edge of the locking body according to the preset position, so that low current can be generated relative to the magnetic induction piece when the ejection block is located at the first position, and high current can be generated relative to the magnetic induction piece when the ejection block is located at the second position, that is, the setting position of the switch base assembly is limited, and the locking effect is improved. And the movement position of the magnetic induction piece along with the ejection block is limited, so that the induction of the Hall sensor and the magnetic induction piece is more accurate, and the accuracy of induction early warning is improved.

    本申请提供一种安全带锁扣,包括:顶出块、磁性感应件和开关座组件。通过在顶出块中设有磁性感应件,使得磁性感应件可随顶出块同步移动。使得现有霍尔传感器与锁舌之间的相互感应改变为霍尔传感器与磁性感应件之间的相互感应,继而使得霍尔传感器与锁舌之间的感应距离变近,从而可提升感应的稳定性。另外,开关座组件按照预设位置设置在锁止主体的边沿,以在顶出块位于第一位置时可相对磁性感应件产生低电流,以及在顶出块位于第二位置时可相对磁性感应件产生高电流,即通过对开关座组件的设置位置进行限定,以及对磁性感应件随顶出块的移动位置进行限定,使得霍尔传感器与磁性感应件的感应更加精确,从而提升感应预警的准确度。
