The invention provides a self-adaptive retractor capable of reducing noise. The self-adaptive retractor comprises a support, a mandrel, a belt sensing fluted disc, a mandrel sleeve, a self-adaptive vehicle sensing assembly, a locking arm, a vehicle sensing pawl and a noise reduction block. Wherein the noise reduction block is in transmission connection with the locking arm, and when the locking arm rotates in the braid pulling-out direction, the noise reduction block is driven to rotate in the direction away from the vehicle sensing pawl, so that the noise reduction block is separated from the vehicle sensing pawl; when the locking arm rotates in the woven belt rewinding direction, the noise reduction block is driven to rotate in the direction close to the vehicle sensing pawl, so that the noise reduction block abuts against the vehicle sensing pawl, and the vehicle sensing pawl abuts against the vehicle sensing arm of the self-adaptive vehicle sensing assembly. According to the self-adaptive retractor capable of reducing noise, the normal vehicle sensing function of the retractor is not affected when the woven belt is pulled out, the vehicle sensing ball can be limited to reduce noise when the woven belt is rewound, the noise reduction structure is simple, and the noise reduction effect is good.

    本发明提供了一种降低噪音的自适应卷收器,包括:支架、芯轴、带感齿盘、芯轴套、自适应车感组件、锁止臂、车感棘爪和降噪块;其中,所述降噪块与所述锁止臂传动连接,当所述锁止臂沿织带拉出方向转动时带动所述降噪块朝远离所述车感棘爪的方向转动,以使得所述降噪块与所述车感棘爪分离;当所述锁止臂沿织带回卷方向转动时带动所述降噪块朝靠近所述车感棘爪的方向转动,以使得所述降噪块与所述车感棘爪相抵并将所述车感棘爪抵压在所述自适应车感组件的所述车感臂上。本发明提供的降低噪音的自适应卷收器,在织带拉出时不影响卷收器的正常车感功能,在织带回卷时能够实现对车感球的限制降低噪音,降噪结构简单,降噪效果好。
