The technical solution of the present invention is further explained with reference to the drawings and the specific embodiments.

As shown in fig. 1 to 24, the reversing child stroller of the present invention includes a stroller frame, a front wheel assembly 2 disposed at a bottom front portion of the stroller frame, a rear wheel assembly 3 disposed at a bottom rear portion of the stroller frame, and a seat assembly 4 disposed on the stroller frame.

The cart frame includes a bottom bracket. In this embodiment, the bottom bracket includes a front bracket 11, a rear bracket 12, and a base 13. The front support 11 and the rear support 12 are respectively arranged at the left side and the right side of the baby stroller, and the base 13 is connected between the front support 11 and the rear support 12 at the left side and the right side. In each of the left and right sides, the upper portion of the front bracket 11, the upper portion of the rear bracket 12, and the left or right end portion of the base 13 are coaxially rotatably connected by a third shaft 53, the front wheel assembly 2 is provided at the lower portion of the front bracket 11 at each side, and the rear wheel assembly 3 is provided at the lower portion of the rear bracket 12 at each side.

The seat assembly 4 includes a seat portion 41 and a backrest portion 42 connected to the seat portion 41. The seat assembly 4 is rotatably provided on the bottom bracket, i.e., the base 13, by a first shaft 51, and the first shaft 51 extends in the up-down direction. The seat assembly 4 has a forward use position and a reverse use position on the bottom bracket, the backrest portion 42 is located at the rear of the seat portion 41 when the seat assembly 4 is in the forward use position, and the child faces forward when seated on the seat portion 41, as shown in fig. 1 and 2; when the seat assembly 4 is in the reverse use position, the back portion 42 is located forward of the seat portion 41 and the child faces rearward when seated on the seat portion 41, as shown in fig. 3.

When the seat assembly 4 is switched between the forward use state and the reverse use state, the seat assembly 4 only needs to rotate relative to the base bracket around the first shaft 51, the child does not need to be taken out of the seat assembly 4, and the seat assembly 4 does not need to be mounted after being detached, so that the seat assembly 4 keeps the forward use state or the reverse use state and rotates around the first shaft 51, as shown in fig. 17 and 20, and the reversing operation of the seat assembly 4 is facilitated.

The stroller further comprises a first locking mechanism disposed between the seat assembly 4 and the base bracket, and when the seat assembly 4 is in the forward use state or the reverse use state, the position between the seat assembly 4 and the base bracket is locked by the first locking mechanism, so that the stroller is in the stable use state.

When the first locking mechanism is in the locked state, the first locking member 61 engages the bottom bracket and the seat assembly 4, respectively, and the seat assembly 4 cannot rotate relative to the bottom bracket about the first axis 51, as shown in fig. 13 and 24. When the first locking mechanism is in the unlocked state, the engagement between the first locking member 61 and the seat assembly 4 is disengaged, the first locking member 61 engages the base frame, and the seat assembly 4 is able to rotate about the first axis 51 relative to the base frame to switch positions between the forward use state and the reverse use state, as shown in fig. 16, 19 and 22.

Specifically, the first locking member 61 is provided with gear teeth on its outer contoured surface, and the bottom bracket and the seat assembly 4 are provided with tooth grooves on their inner contoured surfaces for engagement with the gear teeth. As shown in fig. 6 and 7. When the first locking mechanism is in the locked state, the teeth on the first locking member 61 engage the teeth grooves on the bottom bracket and the seat assembly 4, respectively; when the first locking mechanism is in the unlocked state, the teeth on the first locking member 61 only engage the teeth grooves on the base support and disengage from the teeth grooves on the seat assembly 4. Sliding movement of first locking member 61 relative to the base frame causes the teeth of first locking member 61 to engage or disengage the teeth of the teeth on seat assembly 4.

The stroller further comprises a push rod 14, the push rod 14 is rotatably connected with the seat assembly 4 through a second shaft 52, and in the embodiment, the bottom bracket, the seat assembly 4 and the push rod 14 are sequentially arranged from inside to outside at the joint of the bottom bracket, the seat assembly 4 and the push rod 14.

The stroller also includes a second locking mechanism disposed between the seat assembly 4 and the push rod 14 for locking the position between the seat assembly 4 and the push rod 14 such that the push rod 14 cannot rotate relative to the seat assembly 4 about the second axis 52.

The second locking mechanism includes a second locking member 62, and the first locking member 62 is slidably provided on the seat assembly 4 in a direction along which the length of the second shaft 52 extends.
