Irreversible safety device, vehicle door handle and operation method of vehicle door handle
The invention discloses an irreversible safety device which comprises a safety keeping component, a blocking part and a non-return part, the blocking part bears impact force and rotates relative to a locking position, the blocking part prevents a part to be locked from acting at the locking position, the non-return part abuts against a limiting base, an axial locking action stroke is spaced between the non-return part and the limiting base, and the locking action stroke is larger than the axial locking action stroke. The non-return part rotates and releases the locking action stroke, so that the safety retaining component axially moves to the locking position; the retaining part is formed on the limiting seat, and the retaining part is used for stopping the non-return part at the locking position and limiting the non-return part to rotate at the locking position; the elastic piece is used for applying a first acting force for driving the safety retaining component to rotate and a second acting force for driving the safety retaining component to axially act towards the locking position, and the safety retaining component rotates away from the locking position through the first acting force and forces the non-return part to abut against the retaining part; and the second acting force prevents the safety keeping component from being separated from the locking position.
本发明公开了一种不可逆的安全装置，包括：安全保持构件，具有承接冲撞力而相对锁止位置转动的阻挡部和止逆部，所述阻挡部在锁止位置阻止待锁部件动作，所述止逆部与限位座相抵，并与限位座间隔出轴向的锁止动作行程，且止逆部通过转动并释放锁止动作行程，以使安全保持构件轴向动作至锁止位置；保持部，构成在限位座上，保持部用于与锁止位置的止逆部止挡，并限制止逆部在锁止位置转动；弹性件，用于施以驱使安全保持构件转动的第一作用力，以及驱使安全保持构件朝向锁止位置轴向动作的第二作用力，所述安全保持构件通过第一作用力背离锁止位置转动，并迫使止逆部抵接在保持部上，且所述第二作用力阻止安全保持构件脱离锁止位置。
