Please refer to FIG. 7 , which is a schematic view of the baby stroller 1 after it has been folded. In this embodiment, when the baby stroller 1 is folded, the folded baby stroller 1 can be supported by the feet 1844 of the side wall 184 and the rear wheels 16 to stand. That is to say, the user can easily and quickly place the folded stroller 1 on the ground (indicated by a chain line) alone. This solves the inconvenience of placing existing folded carts.

Regarding the brake mechanism of the brake group 14 , please refer to FIG. 8 , which is a schematic diagram of the drive shaft 146 . The drive shaft 146 includes a larger U-shaped ring 1464 at its middle and smaller U-shaped rings 1466 at its ends. In this embodiment, the drive shaft 146 is mainly formed by a metal rod (or a metal tube in practice). The U-shaped ring 1464 is formed by bending the middle part of the metal rod; the U-shaped ring 1466 is formed by welding an additional piece to the metal rod. Please refer to FIG. 9 , which is a cross-sectional view of the brake set 14 and the platform assembly 18 . The pedal 150 has a sheath 1504 and is inserted into the sheath 1504 by inserting the U-shaped ring 1464 . Likewise, the drive shaft 146 is connected to the brake adapter 148 by fitting the U-shaped ring 1466 into the brake adapter 148; this is not specifically shown. It is supplemented that, in this embodiment, the brake joint 148 is also pivotally connected to the brake housing 142 on the shaft 1484 to make the brake function more stable; but the present invention does not rely on this limit.

Please refer to FIG. 10 . FIG. 10 is a schematic diagram of the configuration of the brake engaging member 148 of the brake set 14 and the hub of the rear wheel. The rear wheel 16 includes a lobe 162 . The brake engagement member 148 can be rotated downward (indicated by the arrow in FIG. 10 ) to snap a stud 1482 between the studs of the lobe 162 . Please refer to FIG. 11 . FIG. 11 is a cross-sectional view of the pedal 150 , showing that the pedal 150 is in an engaged position and a disengaged position. The pedal 150 has two detents 1506 oppositely formed in the through groove 1502 to form two channels 1502a, 1502b respectively corresponding to the disengagement position and the engagement position. But the present invention is not limited thereto, and the number of detents can also be increased to increase the structural strength of the pedal 150 . When the pedal 150 is in the disengaged position (shown in solid lines), the crossbar member 144 passes through the channel 1502a and the brake engaging member 148 is disengaged from the lobe 162 . When the pedal 150 moves downward (as shown by the arrow in FIG. 11 ) to stop at the engagement position (shown in dashed line), the through slot 1502 moves so that the cross bar 144 passes through the passage 1502b , and the drive shaft 146 thus rotates to drive the brake engaging member 148 through the studs 1482 to snap between the studs on the protruding teeth 162 to engage with the protruding teeth 162, thereby braking the Describe rear wheel 16. In other words, by using the detent 1506 to restrain the cross member 144, the pedal 150 can be selectively stopped at the engaging position or the disengaging position. Thereafter, the pedal 150 can be moved upward to stop at the disengaged position. It is supplemented that, in practice, the position of the pedal 150 can be maintained in other ways, such as utilizing the frictional force between the cross bar 144 and the through slot 1502 .

However, although the two channels 1502a, 1502b are formed by the through groove 1502 in the above embodiment, the present invention is not limited thereto. Please refer to FIG. 12 , the through groove 1503 of the pedal 151 has only a single passage for the cross bar 144 to pass through, which can improve the fixing strength of the pedal 151 . The through groove 1503 can form a plurality of detents as required, which can reduce the frictional force of the pedal 151 rotation and improve the structural strength.

As explained above, the baby stroller with the platform combination of the present invention can stand alone without any auxiliary device by using the feet on the side walls and the rear wheels. In addition, through the detachable design between the side wall and the brake group, when the platform assembly collides with an object, it can rotate upwards around the rear cross bar to avoid damage.

The above descriptions are only preferred embodiments of the present invention, and all equivalent changes and modifications made according to the claims of the present invention shall fall within the scope of the present invention.
