In this embodiment, the push handle bar 100 and the upper bracket 200 are generally located above the lower bracket 300 except for the leg rest 226, and the upper bracket 200 is rotatably connected to the lower bracket 300 about the central axis 500, so that the push handle bar 100 and the upper bracket 200 can rotate as a whole about the central axis 500 in a horizontal plane with respect to the lower bracket 300. Referring to fig. 6 to 9, when the upper bracket 200 is rotated about the central shaft 500, the leg rest 226 is only slightly rotated upward to be lifted without moving the child out of the seat 220, and the rotation is performed without hindrance, which greatly facilitates the operation.

The upper bracket 200 can freely rotate 180 degrees around the central shaft 500 from the forward position to the reverse position; accordingly, the stroller has at least two use states, in the present embodiment, the two use states are a forward pushing state and a backward pushing state: when the stroller is in the forward pushing state as shown in fig. 1, the seat 220 faces forward and back to the handle bar 100, the back bar 225 of the seat 220 is inclined backward, the handle bar 224 is forward, and the upper bracket 200 is in the forward position; when the stroller is in the reverse-push state as shown in fig. 9, the seat 220 is oriented rearward and faces the push handle bar 100, the back rest bar 225 of the seat 220 is inclined forward, the grab bar 224 is oriented rearward, and the upper bracket 200 is located at the reverse position; the fore-aft direction of the stroller is referenced to the arrangement of the front wheel assembly 410 and the rear wheel assembly 420.

The left, right, height, front and back directions of the stroller in the invention refer to the left, right, height and front and back directions of the stroller when the stroller is in a forward pushing state (as shown in fig. 1) or a backward pushing state (as shown in fig. 9); the vertical and horizontal directions refer to the vertical and horizontal positions (as shown in fig. 1 and 9) when the stroller is placed on a horizontal ground in the forward pushing state or the backward pushing state, so as to facilitate the description of the present invention.

At least two locking devices are arranged between the handle bar 100, the upper bracket 200 and the lower bracket 300 of the children's cart. In this embodiment, the locking device includes a first locking device for locking the handle bar 100 with respect to the upper bracket 200, and a second locking device for locking the upper bracket 200 with respect to the lower bracket 300, and the first locking device and the second locking device can be unlocked and locked in linkage. The first locking means is provided between the rotating part 110 of the push stick lever 100 and the connecting part 223 of the seat 220; the second locking means is provided between the connector and the cross bracket 330. The specific structure of the locking device can adopt the prior art, and the invention is not limited.

Referring to fig. 6 to 9, when the stroller needs to be converted from the forward pushing state to the backward pushing state, the first locking device is first unlocked, the push handle rod 100 is driven to rotate forward around the first rotation center line 1 relative to the seat 220, and the second locking device is linked to unlock, so that the push handle rod 100 and the upper bracket 200 as a whole can rotate around the central shaft 500 in a horizontal plane; when the push handle bar 100 and the upper bracket 200 rotate 180 ° around the central axis 500 to the position shown in fig. 8, the push handle bar 100 is further rotated backward around the first rotation center line 1 relative to the seat 220 until the first locking device is unlocked and the second locking device is locked, and the stroller is switched to the reverse pushing state shown in fig. 9.

When the stroller needs to be switched from the reverse pushing state to the forward pushing state, the above steps are operated in the reverse direction, and are not described herein again.

In addition, each support of children's shallow in this embodiment all can fold each other and draw in, and the frame volume under fold condition reduces, portable and accomodate. The folding structure of the frame can adopt the prior art, and the invention is not limited.

The children's shallow of this embodiment can realize just pushing away with the backstepping as required, and just the in-process of the conversion of just pushing away state and backstepping state need not to shift out seat 220 with children, and is easy and simple to handle.

The above embodiments are merely illustrative of the technical ideas and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and implement the present invention, and not to limit the protection scope of the present invention.
