The invention discloses an intelligent pre-tightening locking device for a safety belt and a use method of the intelligent pre-tightening locking device. The intelligent pre-tightening locking device comprises a power input mechanism, a driving mechanism and a rolling-up mechanism; the device can ensure that the safety belt can stretch out and draw back freely like a common safety belt when a vehicle is not in danger, once the vehicle is judged to be in danger or has the possibility of danger, a control unit of the safety belt mechanism sends out a pre-tightening signal, an early warning signal and a locking signal, and the safety belt can be rolled back and tightened in the reverse direction at the moment, the slack amount between the passenger and the safety belt is reduced; and meanwhile, the pulling function of the safety belt is locked through the electric control locking mechanism, and the situation that the loosening amount is increased due to the fact that the safety belt is pulled out due to forward-rushing inertia of the body of the passenger is avoided. When the speed reduction degree of the vehicle is too large, secondary collision between the passengers and hard objects in the vehicle due to the safety slack amount and gaps or extremely dangerous conditions caused by throwing the passengers out of a safety belt or even throwing the passengers out of the vehicle are prevented, so that the safety protection capability on the passengers is improved.
本发明公开了一种安全带智能预紧锁止装置及其使用方法,该装置包括动力输入机构、驱动机构和卷收机构;该装置能保证在车辆不发生危险时和普通安全带一样能够自由伸缩,而一旦判断车辆发生危险或有发生危险的可能,安全带机构的控制单元将发出预紧信号、预警信号和锁止信号,此时安全带将会被反方向回卷收紧,减少乘员与安全带之间的松弛量,同时利用电控锁止机构将安全带的抽拉功能锁止,防止因乘员的身体前冲惯性再把安全带拉出而导致的松弛量增加。也防止车辆减速度过大时,安全松弛量和间隙会使乘员与车内硬质物体发生二次碰撞,或被甩出安全带甚至被甩出车辆而发生极度危险状况,以此提高对乘员的安全保护能力。
