The invention provides an electronic vehicle sensing type safety belt retractor assembly. The electronic vehicle sensing type safety belt retractor assembly comprises a belt winding drum installed in a frame. The locking device is arranged to lock the tape winding drum in the pulling-out direction of the woven tape; the belt sensing assembly is provided with ratchets and is arranged to drive a locking device to lock the belt winding drum when the ratchets are meshed; the electromagnetic switch is provided with a pawl, and the pawl is subjected to spring force or magnetic force in the direction opposite to the direction meshed with the ratchets; the return assembly is provided with a pressing spring; the restraining spring limits the downward pressing spring when the tape winding drum rotates in the pulling-out direction of the woven tape, and releases the downward pressing spring when the tape winding drum rotates in the direction opposite to the pulling-out direction of the woven tape; when the return assembly is located at the unlocking position and the restraining spring is located at the position for releasing the downward pressing spring, the downward pressing spring is matched with the pawl in an extrusion mode, and the pawl is made to rotate to the position where the pawl is meshed with the ratchets. According to the electronic vehicle sensing type safety belt retractor assembly, the first-time wearable function of an electronic vehicle sensing type safety belt when the electronic vehicle sensing type safety belt is not powered on is achieved.

    本发明提供一种电子车感式安全带卷收器总成,包括安装在框架中的卷带筒;设置为在所述织带的拉出方向锁止所述卷带筒的锁止装置;具有棘齿的带感总成,其设置为在棘齿啮合时驱动锁止装置锁止所述卷带筒;具有棘爪的电磁开关,棘爪在与棘齿啮合的相反方向受弹簧力或磁力作用;回位组件,具有下压弹簧;和抑制弹簧,其在卷带筒沿织带的拉出方向转动时限位下压弹簧,在卷带筒沿织带拉出方向的相反方向转动时释放下压弹簧;在回位组件处于解锁位置且抑制弹簧处于释放所述下压弹簧的位置时,下压弹簧与所述棘爪挤压配合,使得棘爪转动至与所述棘齿啮合的位置。本发明的电子车感式安全带卷收器总成实现了电子车感式安全带在未通电时的首次可佩戴功能。
