The invention provides a safety belt tensioning detection device, a safety belt tensioning detection method and a safety seat, and relates to the technical field of safety seats. The safety belt tensioning detection device comprises a fastener, a microswitch and a tensioning detection sensor; the microswitch and the tensioning detection sensor are respectively mounted on the fastener; the microswitch is used for detecting the connection state of the fastener; the tensioning detection sensor is used for detecting the pulling force borne by the buckling piece. The safety belt tensioning detection method comprises the following steps that a state signal of a microswitch is recognized, and the connection state of a fastener is judged; when the fastener is in the locking state, the use state of the safety belt is judged according to a signal of the tensioning detection sensor; and when the fastener is in the unlocking state, an alarm signal is sent out through the prompting device. According to the safety belt tensioning detection device, the safety belt tensioning detection method and the safety seat provided by the invention, the connection state of the fastener and the tension of the safety belt can be accurately detected.

    本发明提供了一种安全带拉紧检测装置、安全带拉紧检测方法及安全座椅,涉及安全座椅技术领域,本发明提供的安全带拉紧检测装置,包括:卡扣件、微动开关和拉紧检测传感器;微动开关和拉紧检测传感器分别安装于卡扣件上;微动开关用于检测卡扣件的连接状态;拉紧检测传感器用于检测卡扣件受到的拉力。本发明提供的安全带拉紧检测方法包括以下步骤:识别微动开关的状态信号,并判断卡扣件的连接状态;当卡扣件处于锁止状态时,根据拉紧检测传感器的信号判断安全带的使用状态;当卡扣件处于解锁状态时,通过提示器件发出告警信号。本发明提供的安全带拉紧检测装置、安全带拉紧检测方法及安全座椅,可以准确检测卡扣件的连接状态和安全带的拉力。
