Example 1

As shown in fig. 1 to 9, the stroller of the present invention includes a stroller frame having an unfolded state and a folded state, a seat assembly provided on the stroller frame, and a locking mechanism for locking the stroller frame in the unfolded state.

The seat assembly includes a seat 21 and a backrest 22 pivotally connected to the seat 21. The backrest 22 is rotatable relative to the seat 21 to move toward or away from the seat 21. When the stroller is in the unfolded state, the backrest 22 is away from the seat 21, as shown in fig. 1. When the stroller is folded from the unfolded state, the backrest 22 is rotated to be close to the seat 21, as shown in fig. 5.

The locking mechanism has a locking state and an unlocking state, when the baby stroller is in the unfolding state, the locking mechanism is in the locking state, and when the locking mechanism is in the unlocking state, the stroller frame can be folded.

The cart frame comprises a first part 11 and a second part 12 which are rotatably connected, and a locking mechanism is used for locking the relative positions of the first part 11 and the second part 12. The locking mechanism comprises a locking member 3 slidably arranged between a first part 11 and a second part 12. When the locking mechanism is in the locked state, the locking member 3 cooperates with the first part 11 and the second part 12, respectively, as shown in fig. 12. When the locking mechanism is in the unlocked state, the locking member 3 engages the first part 11 and disengages from the second part 12, as shown in fig. 13.

In a specific embodiment, the locking member 3 is provided with locking teeth, and the first part 11 and the second part 12 are provided with splines for engaging with the locking teeth. When the locking mechanism is in the locked state, the locking teeth on the locking member 3 engage with the splines on the first and

second parts

11, 12, respectively. When the locking mechanism is in the unlocked condition, the locking teeth on the locking member 3 engage the splines on the first part 11 and disengage the splines on the second part 12.

In this embodiment, the first member 11 is a front bracket, the second member 12 is a rear bracket, a front wheel assembly 1001 is connected to the lower end of the front bracket, and a rear wheel assembly 1002 is connected to the lower end of the rear bracket. The reverse is also possible.

The stroller further comprises a first elastic member 4, and the elastic force of the first elastic member 4 is used for driving the locking member 3 to slide in a direction that the locking member 3 is engaged with the second component 12, i.e. the elastic force of the first elastic member 4 resets the locking mechanism from the unlocked state to the locked state. One end portion of the first elastic member 4 is provided on the first member 11, and the other end portion of the first elastic member 4 is provided on the locking member 3, as shown in fig. 12 and 13.
