Driving mechanism and door lock
The invention provides a driving mechanism and a door lock. The driving mechanism comprises a first ratchet wheel, a second ratchet wheel, a first pawl, a second pawl, a rotating piece, a driven piece and an output piece. The first ratchet wheel and the second ratchet wheel can rotate, the first pawl can be meshed with or separated from the first ratchet wheel, the second pawl can be meshed with or separated from the second ratchet wheel, and the rotating piece can rotate. The driven piece has a free state and a synchronous state, the driven piece is eccentrically provided with a driven part, and the driven part is clamped between the first pawl and the second pawl. The output piece can abut against the driven part and is driven by the driven part to rotate. A user can control the rotating part to rotate manually or electrically, and finally the output part can still rotate, the first ratchet wheel and the second ratchet wheel do not need to rotate in the rotating process, the situation that the first ratchet wheel and the second ratchet wheel need to be driven back to move is avoided, force needed for driving the rotating part is reduced, and the lock opening and closing difficulty is lowered.
本申请提供了驱动机构及门锁，驱动机构包括第一棘轮与第二棘轮、第一棘爪与第二棘爪、转动件、从动件、以及输出件。第一棘轮与第二棘轮均能够转动，第一棘爪能够与第一棘轮相啮合或相分离，第二棘爪能够与第二棘轮相啮合或相分离，转动件能够转动。从动件具有游离状态与同步状态，从动件偏心地设有从动部，从动部夹持于第一棘爪与第二棘爪之间。输出件能够抵持从动部，并在从动部的带动下进行转动。用户可通过手动或电动等方式控制转动件转动最终仍然可实现输出件转动，并且在转动的过程中第一棘轮与第二棘轮无需转动，避免了需要返驱第一棘轮与第二棘轮进行运动，降低了驱动转动件所需的力，降低了开关锁的难度。
