The invention discloses a synchronous unlocking mechanism. The synchronous unlocking mechanism comprises a lifting handle, a locking piece, a resetting piece and a traction piece, the locking piece is arranged on the pivot, the backrest and the seat frame in a sliding mode so that the locking piece can be provided with a locking position and an unlocking position, the carrying handle is connected with the backrest and/or the seat frame in a pivoted mode through a pivot line, and the carrying handle is further in linkage with the locking piece. The reset piece is located between the locking piece and the seat frame or between the locking piece and the backrest, and the reset piece has the trend of driving the locking piece to slide to the locking position; the first end of the traction piece is assembled and connected with the lifting handle, and the second end of the traction piece is assembled and connected with a joint locking piece in the frame; when the linkage locking piece is switched to the unlocking position, the lifting handle drives the joint locking piece to perform unlocking motion through the traction piece; and synchronous unlocking of the frame and the backrest is realized, so that the folding operation is very simple and convenient. In addition, the invention further discloses the baby carriage.
本发明公开了一种同步释锁机构,包含提把、锁定件、复位件及牵拉件。锁定件滑设于枢轴、背靠及座架,以使锁定件具有锁定位置和释锁位置,提把借助一枢轴线与背靠和/或座架枢接,提把还与锁定件连动;复位件位于锁定件与座架之间或位于锁定件与背靠之间,复位件具有驱使锁定件滑移至锁定位置的趋势;牵拉件的第一端与提把装配连接,牵拉件的第二端与车架中的关节锁固件装配连接;提把在连动锁定件切换至释锁位置过程中通过牵拉件带动关节锁固件做释锁运动;实现车架与背靠的同步释锁,从而使得折叠操作十分简便。另,本发明还公开了一种婴儿车。
