The invention discloses a three-point type self-adaptive safety belt and a method thereof. The three-point type self-adaptive safety belt comprises a control device, a gravity sensor, a contact sensor, a tension sensor, a driving motor and a retractor mandrel. The gravity sensor is arranged on a safety belt seat, and the output end of the gravity sensor is connected with the input end of the control device; the contact sensor is arranged on a safety belt lock catch, and the output end of the contact sensor is connected with the input end of the control device; the tension sensor is arranged on the safety belt lock catch, and the output end of the tension sensor is connected with the input end of the control device; and the driving motor is in transmission connection with the retractor mandrel through a gear transmission device, a woven belt of the safety belt is wound on the retractor mandrel, and the control device controls the driving motor to drive the retractor mandrel to rotate, stretch out and retract the woven belt of the safety belt. The control device controls the driving motor to rotate according to detection data of the tension sensor, the retractor mandrel is driven to stretch out and retract the woven belt of the safety belt, and the comfort degree of a passenger wearing the safety belt is improved.

    本发明公开了一种三点式自适应安全带和方法,包括控制装置、重力传感器、接触传感器、拉力传感器、驱动电机和卷收器芯轴;重力传感器设置在安全带座椅上,重力传感器的输出端连接控制装置的输入端;接触传感器设置在安全带锁扣上,接触传感器的输出端连接控制装置的输入端;拉力传感器设置在安全带锁扣上,拉力传感器的输出端连接控制装置的输入端;驱动电机通过齿轮传动装置与卷收器芯轴传动连接,卷收器芯轴上缠绕安全带的织带,控制装置控制驱动电机带动卷收器芯轴转动,伸出和收回安全带的织带。控制装置依据拉力传感器的检测数据控制驱动电机转动,带动卷收器芯轴伸出和收回安全带的织带,提高乘客佩戴安全带的舒适度。
