According to the belt sensing locking mechanism of the safety belt, a planetary gear mechanism is additionally arranged on a belt winding drum, and an inner gear ring of a planetary gear is connected with the belt winding drum and serves as a driving part; the planetary gear carrier is fixed, and the sun gear and the torsion bar are integrated to form a torsion bar shaft serving as a driven part; when the ratchet wheel locking mechanism rotates, the driven part can be accelerated greatly, so that the connected ratchet wheel locking mechanism obtains increased angular velocity, the locking pawl obtains larger centrifugal force and pops up more sensitively and quickly, and the purpose of shortening the locking reaction time is achieved. According to the mechanism, the number of the locking pawls is increased, a three-blade pawl structure is adopted, the locking pawls are installed on the centrifugal rotating disc, the three return springs are connected pairwise, return force is provided, and the locking pawls can rotate around the fixing shaft to be popped out, so that the locking reliability is improved. The invention further discloses an automobile applying the safety belt sensing locking mechanism.

    本发明公开了一种安全带带感锁止机构,在卷带筒上新增行星齿轮机构,行星齿轮内齿圈与卷带筒相连,作为主动件;行星齿轮架固定,太阳轮与扭力杆为一体,构成扭力杆轴,作为被动件;被动件能得到较大的升速,使连接的棘轮锁止机构获得增大的角速度,以使锁止棘爪获得更大的离心力,更灵敏迅速的弹出,以此达到缩短锁止反应时间的目的。本机构增加了锁止棘爪的数量,采用了三叶片棘爪结构,锁止棘爪安装在离心转盘上,并用三个回位弹簧两两相连,提供回位力,可绕固定轴旋转弹出,来提高锁止的可靠性。本发明还公开了一种应用上述安全带带感锁止机构的汽车。
