The stroller frame includes two side brackets 100 disposed on the left and right sides, and each side bracket 100 has a bracket rod extending in the up-down direction.

The stroller frame also includes a seat support 60 for grafting and installing a child seat 70, so that the child stroller has a seat or an additional seat. Referring to Figures 11 to 13, the seat support 60 includes a support seat 1, which has at least two support rods 11 arranged on the left and right sides, each support rod 11 has a mounting end 11a, and the mounting end 11a is provided with a support connector 2 that can be matched with the child seat 70. The support seat 1 can be connected to the stroller frame in a flipping manner along the front-back direction, and the seat support 60 is located between the support rods on both sides along the left-right direction.

In this way, the seat pocket bracket 60 has an open state and a folded state. When the seat pocket bracket 60 is converted from the open state to the folded state, the bracket connector approaches the support rod in the front-to-back direction to be connected with the child seat pocket 70 to achieve the grafting and installation of the child seat pocket 70, as shown in Figures 1 and 2; when the seat pocket bracket 60 is converted from the folded state to the open state, the bracket connector moves away from the support rod in the front-to-back direction, the seat pocket bracket 60 is not grafted with the child seat pocket 70, and the bracket seat 1 is flipped relative to the stroller frame so that the bracket rod 11 and the support rod on the side bracket 100 are retracted to reduce the space occupied by the seat pocket bracket 60, and it is beneficial to the relative retraction of the various rods when the stroller frame is folded, see Figures 7 to 8.

In this embodiment, on the left and right sides of the cart frame, the bracket rod 11 is rotatably connected to the support rod on the same side, and a bracket locking piece for locking the bracket rod and the support rod on the same side is also provided. Specifically, referring to Figures 11 to 13, the bracket rods 11 on both sides are provided with connecting sleeves 13, and the bracket seat 1 is locked and installed on the cart frame by connecting and locking the connecting sleeves 13 with the support rods on the corresponding sides, and the bracket locking piece is provided between the connecting sleeves 13 and the support rods.

The bracket seat 1 also includes a bracket cross bar 12 connected between the bracket rods 11 on both sides, and the bracket cross bar 12 and the bracket rods 11 on both sides form a U-shaped structure. In the specific setting, the bracket cross bar 12 and the bracket rods 11 on both sides can be integrally formed, and the bracket cross bar 12 is also provided with a bracket unlocking member 6 for unlocking the bracket locking members on both sides.

As shown in Figures 11 to 13, on the left and right sides of the seat bag bracket 60, the bracket connector 2 can be installed on the mounting end 11a of the bracket rod 11 in a flipping manner relative to the bracket rod 11, and the bracket connectors 2 on both sides are arranged facing each other relative to the flipping direction of the bracket rod 11 on the same side. This allows the seat bag bracket 60 to have an unfolded state and a folded state. When the seat bag bracket 60 is in the unfolded state, the bracket connectors 2 on both sides extend from the mounting ends 11a of the bracket rod 11 on both sides respectively, so as to be used for grafting and installing with the child seat 70, as shown in Figure 11; when the seat bag bracket 60 is in the folded state, the bracket connectors 2 on both sides flip toward each other and are folded with the bracket rod 11 on the corresponding side, and the two bracket connectors 2 are folded between the bracket rods 11 on both sides along the left-right direction.

In this embodiment, on the left and right sides of the seat support 60, the support connector 2 is connected to the mounting end 11a of the support rod 11 through the adapter 3. Specifically, each support connector 2 has a grafting end 2a for connecting to the child seat 70, and a connecting end 2b for connecting to the support rod 11, wherein the grafting end 2a and the child seat 70 to be grafted have a matching detachable connection structure. The adapter 3 is arranged between the connecting end 2b and the mounting end 11a of the support rod 11, and the following arrangement is specifically adopted here: one end of the adapter 3 is pivotally connected to the mounting end 11a through the first axis 4, and the other end of the adapter 3 is pivotally connected to the connecting end 2b of the support connector 2 through the second axis 5, wherein the axis center lines of the first axis 4 and the second axis 5 are arranged parallel to each other, so that the support connector 2 can be tightly fitted and folded when it is flipped relative to the support rod 11.

On the seat bag bracket 60 used in this embodiment, a first receiving groove (not shown in the figure) is provided on the mounting end 11a, and a second receiving groove (not shown in the figure) is provided on the bracket connector 2. When the seat bag bracket 60 is in the unfolded state, one end of the connector 3 is received in the first receiving groove and the other end thereof is received in the second receiving groove, and the end of the connecting end 2b on the bracket connector 2 directly contacts the mounting end 11a, that is, the adapter 3 cannot be seen from the outside when the seat bag bracket 60 is unfolded, which makes its appearance more beautiful and simple when unfolded. In the specific setting, the first receiving groove and the second receiving groove can be set as U-shaped opening grooves with the opening facing the inner side of the bracket seat 1, and the mouths of the first receiving groove/the second receiving groove on both sides are arranged oppositely.

As shown in FIGS. 1 to 10 , on the stroller frame of this embodiment, the side bracket 100 on each side includes a front bracket 10, a rear bracket 20 and a push rod 30 that are relatively rotatably connected, and the wheel assembly includes a front wheel assembly 40 and a rear wheel assembly 50, the front wheel assembly 40 is arranged at the lower part of the front bracket 10, and the rear wheel assembly 50 is arranged at the lower part of the rear bracket 20.
