One end of the second elastic member 7 is provided on the second locking member 6, and the other end of the second elastic member 7 is provided on the bracket 2.
The stroller further comprises an unlocking mechanism that can actuate the first locking mechanism to unlock when the first locking mechanism operates the unlocking mechanism in a locked state.
The unlocking mechanism comprises an unlocking knob 81, a traction rope (not shown in the figure) and a first driving piece 82, wherein the unlocking knob 81 and the first driving piece 82 can be slidably arranged, the unlocking knob 81 is operated by a human hand when the first locking mechanism is unlocked, the first driving piece 82 is matched with the first locking piece 5, one end part of the traction rope is arranged on the unlocking knob 81, and the other end part of the traction rope is arranged on the first driving piece 82.
One of the first driving member 82 and the first locking member 5 is provided with a first inclined surface 821, the other is fixedly provided with a fixed column 51, and the first inclined surface 721 is abutted against the fixed column 51 for matching.
In this embodiment, the unlocking knob 81 and the first driving member 82 are both slidably provided on the bracket 2, the first inclined surface 821 is provided on the first driving member 82, and the fixing post 51 is provided on the first locking member 5.
When the first locking mechanism pulls the unlocking knob 81 to slide relative to the bracket 2 in the locked state, the first driving piece 82 is pulled by the traction rope to slide relative to the bracket 2, and the first inclined surface 821 is matched with the abutting of the fixed column 51 to drive the first locking piece 5 to slide, so that the first locking mechanism is separated from the first locking groove 112, and the first locking mechanism is unlocked. In unlocking the first locking mechanism, the sliding direction of the first driving member 82 is perpendicular to the sliding direction of the first locking member 5.
The stroller further comprises a second drive member 9, the second drive member 9 being slidably arranged on the rear support 12 or the carrier 2, in this embodiment the second drive member 9 being slidably arranged in the carrier 2. The second driving member 9 cooperates with the second locking member 6 when the second locking mechanism is in the locked state. When the baby carriage is rotated from the unfolded state to the direction of approaching the rear bracket 12 by folding the front bracket 11, the front bracket 11 can be matched with the second driving piece 9, so that the second driving piece 9 is driven to slide relative to the rear bracket 12 or the bracket 2 when the front bracket 11 is rotated, and the second locking piece 6 is driven to slide, so that the second locking mechanism is unlocked.
Specifically, the upper part of the front frame 11 is provided with a helicoidal surface 113, and the second driving member 9 is distanced from this helicoidal surface 113 when the stroller is in the unfolded state. When the stroller is folded, the front bracket 11 rotates in the direction approaching to the rear bracket 12, so that the spiral surface 113 gradually approaches to the second driving piece 9 until the spiral surface 113 is abutted against one end of the second driving piece 9 to be matched, and at the moment, the front bracket 11 can drive the second driving piece 9 to slide relative to the bracket 2 when continuing to rotate. In this embodiment, an end portion of the second driving member 9 that can be engaged against the spiral surface 113 is a cambered surface 91.
The other end of the second driving member 9 is provided with a second inclined surface 92, and when the second locking mechanism is in the locked state, the second inclined surface 92 is in abutting engagement with one end of the second locking member 6. When the second driving member 9 slides, the second inclined surface 92 is matched with the second locking member 6 in an abutting manner, so that the second locking member 6 can be driven to slide relative to the bracket 2, and the sliding direction of the second driving member 9 is perpendicular to the sliding direction of the second locking member 6.
When the stroller is in the deployed state, both the first and second locking mechanisms are in the locked state, as shown in fig. 1 and 2.
When the stroller is folded from the unfolded state, the unlocking knob 81 is operated to slide relative to the bracket 2, the first driving piece 82 is pulled by the traction rope to slide relative to the bracket 2, the first locking piece 5 slides relative to the bracket 2 through the abutting fit of the first inclined surface 821 and the fixed column 51 until the first locking piece 5 is separated from the first locking groove 112, and the first locking mechanism is unlocked. The front bracket 11 is rotated towards the direction close to the rear bracket 12 until the spiral surface 113 on the front bracket 11 is matched with one end part of the second driving piece 9 in a propping way, at the moment, when the front bracket 11 continues to rotate along the current direction, the second driving piece 9 can be driven to slide relative to the bracket 2, and the second locking piece 6 is driven to slide relative to the bracket 2 through the propping and matching of the second inclined surface 92 and one end part of the second locking piece 6 until the second locking piece 6 is separated from the second locking groove 122, so that the second locking mechanism is unlocked. The bracket 2 can be rotated downward to be close to the rear bracket 12, and the front bracket 11 can be rotated further rearward to be close to the rear bracket 12, as shown in fig. 11 and 12. Until the front frame 11, rear frame 12 and carrier 2 are brought together, and finally folded as shown in fig. 13 and 14.
