The invention relates to an automobile door lock unlocking device which comprises a worm gear, a crank connecting rod, an unlocking pull rod, a ratchet wheel, a pawl spring, a pawl and an unlocking pull rod spring. A clamping foot is arranged on the worm gear, one end of the crank connecting rod is connected with the worm gear in a matched mode, the other end of the crank connecting rod is connected with the unlocking pull rod, the pawl is arranged at the other end of the unlocking pull rod, and the ratchet wheel is arranged on one side of the pawl. An auxiliary pawl is arranged on the pawl, one end of the auxiliary pawl is a fixed end, the other end of the auxiliary pawl is a free end, the fixed end is rotationally arranged on the pawl, the free end rotates on the pawl along the fixed end, a rolling wheel is arranged at the free end, and the rolling wheel makes contact with the side, facing the rolling wheel, of the pawl. According to the automobile door lock unlocking device, the rolling wheel is arranged at the end of the side, making contact with the ratchet wheel, of the pawl, the rolling wheel makes contact with the ratchet wheel along with rotation of the pawl, contact between the pawl and the ratchet wheel is smooth, friction force generated by mutual contact between the ratchet wheel and the pawl is reduced, and the service life of the ratchet wheel and the service life of the pawl are prolonged.
本发明涉及一种汽车门锁解锁装置，包括蜗轮、曲柄连杆、解锁拉杆、棘轮、棘爪弹簧、棘爪和解锁拉杆弹簧；所述蜗轮上设有卡脚，所述曲柄连杆一端匹配的与所述蜗轮连接，另一端与解锁拉杆连接，所述解锁拉杆另一端设有棘爪，所述棘爪一侧设有棘轮；所述棘爪上设有辅助棘爪，所述辅助棘爪一端为固定端，另一端为自由端，所述固定端转动设置在棘爪上，所述自由端沿所述固定端在棘爪上转动，所述自由端上设有滚轮，所述滚轮与朝向滚轮的所述棘爪一侧相接触。本发明在棘爪与棘轮相接触的一侧端部上设置滚轮，滚轮随棘爪的转动与棘轮相接触，使得棘爪与棘轮间的接触较为顺滑，减小棘轮和棘爪间相互接触产生的摩擦力，延长棘轮和棘爪的使用寿命。
