Abstract

The invention discloses an unlocking device and a baby stroller. The unlocking device is used for unlocking a locking device arranged between a base frame and a movable frame which are movably connected, the movable frame comprises a first rod and a second rod which relatively slide and stretch along a length direction, and the first rod is connected with the base frame. The unlocking device comprises an unlocking push rod arranged on the first rod in a sliding mode, an unlocking push rod reset piece and a rotating ejector block rotationally arranged on the second rod, when the movable frame is in the stretching-out state, the unlocking push rod is separated from the driving end of the rotating ejector block, and when the movable frame is in a contraction state, the driving end of the rotary ejector block is connected with the unlocking push rod, and at the moment, when the rotary ejector block is driven to rotate, the unlocking push rod can be driven to move to unlock the locking device. When the unlocking device is used on the baby stroller, the contraction function of the push rod assembly in the length direction is not affected, so that the baby stroller has a larger pushing height and a smaller folding size, and the unlocking operation is simple and easy to implement.

Description

technical field [0001] The invention relates to an unlocking device for a baby carriage and the baby carriage. Background technique [0002] Existing strollers generally include a rod and a locking device for locking the rod. For example, a stroller includes a push rod assembly, and in order to be able to be folded so as to accommodate and transport the stroller, the push rod assembly is usually relatively rotatably connected to the bottom frame, and the bottom frame is mainly composed of a front wheel bracket provided with a front wheel assembly and a It is composed of a rear wheel bracket with a rear wheel assembly; in order to make the stroller unfold stably, a locking device is provided between the push rod assembly and the bottom frame to stabilize the push rod in the unfolded state; in addition, an unlocking part is required to enable The locking mechanism is unlocked to allow the push bar assembly to rotate when the stroller is folded. [0003] In the prior art, mos...
