In other alternative embodiments, the number of the seat support rods 2 may be multiple, and a plurality of the seat support rods 2 are provided with a mounting portion, and the plurality of mounting portions can be matched with the mounting seat 5. For example, four seat support rods 2 are respectively inserted into the fixing base 1 and extend obliquely forward and upward and obliquely rearward and upward to the left and right sides, respectively, to form four mounting portions, and the seat 5 is fixed to the frame through the four mounting portions.

Alternatively, the saddle 5 is made of a foldable material. Preferably, the seat 5 may be made of fabric, and the structure for engaging, hooking or hanging with the hanging part may be made of fabric or plastic, so as to reduce the weight of the seat 5 and be suitable for folding and storage.

Referring to fig. 5 to 8, in order to further facilitate the storage and volume reduction of the frame, the fixing base 1 may include an upper fixing base 11 and a lower fixing base 12 that are arranged in a cross manner, and the upper fixing base 11 and the lower fixing base 12 are pivoted to be able to rotate relatively to form an unfolded state or a folded state; the seat supporting rod 2, the wheel bracket 3 and the push rod 4 are inserted into the upper fixing seat 11 and/or the lower fixing seat 12.

In this embodiment, the upper fixing base 11 and the lower fixing base 12 are arranged in an up-and-down overlapping manner, the middle portions of the upper fixing base and the lower fixing base are recessed, the surfaces of the recessed portions are planes, the upper fixing base 11 and the lower fixing base 12 are attached and overlapped through the respective recessed portions and are pivoted through the pin shaft 13, and therefore the upper fixing base and the lower fixing base can rotate relatively. In addition, the maximum and minimum included angles between the upper fixing seat 11 and the lower fixing seat 12 can be defined by the width and length of the recess or by arranging a limiting structure such as a bump at the recess.

Preferably, the stroller further comprises a holding mechanism capable of holding the upper holder 11 and the lower holder 12 in the unfolded state. As shown in fig. 1, the holding mechanism can be realized by the structure of the push rod 4, that is, after two ends of the rigid push rod 4 are respectively inserted into the upper fixing seat 11 and the lower fixing seat 12, the rotation of the fixing seats 1 and the lower fixing seat 12 can be limited, so that the upper fixing seat 11 and the lower fixing seat 12 are kept in the unfolded state.

Optionally, a spring may be further disposed between the upper fixing seat 11 and the lower fixing seat 12, and two ends of the spring are respectively connected to or abutted to the same side of the upper fixing seat 11 and the lower fixing seat 12 at the pivot joints thereof, so that the extension elastic force of the spring acts on the upper fixing seat 11 and the lower fixing seat 12 respectively, and the upper fixing seat 11 and the lower fixing seat 12 are further kept in the unfolded state.

Optionally, a torsion spring may be sleeved on the pivot shaft of the upper fixing seat 11 and the lower fixing seat 12, and the fixing seat 1 and the lower fixing seat 12 are kept in the unfolded state by the torsion spring.

The installation methods of the spring and the torsion spring are common and are not described herein.

Preferably, the seat support bar 2 and/or the wheel carrier 3 and/or the push rod 4 are formed by at least two tube sections that are movably inserted into each other, and the elastic member is further connected between the tube sections that form the seat support bar 2 and/or the wheel carrier 3 and/or the push rod 4. Thereby after dismantling seat bracing piece 2, wheel support 3 and push rod 4 and fixing base 1, seat bracing piece 2 and/or wheel support 3 and/or push rod 4 can also carry out self and dismantle to further make this children's shallow be convenient for accomodate and reduce the volume.

In the present embodiment, the seat support rod 2, the wheel bracket 3, and the push rod 4 are all hollow structures. A first inserting part 14, a second inserting part 15 and a third inserting part 16 which are respectively used for inserting the seat supporting rod 2, the wheel bracket 3 and the push rod 4 are formed on the fixed seat 1; the elastic element comprises a plurality of elastic ropes 7, and each elastic rope 7 is respectively fixed and penetrated in the seat supporting rod 2, the wheel bracket 3 and the push rod 4 and is respectively connected with the first insertion part 14, the second insertion part 15 and the third insertion part 16.

Illustratively, as shown in fig. 3, in the present embodiment, the number of the seat support rods 2 is two, and the two seat support rods 2 are respectively inserted into the first insertion portion 14 formed at the front side of the frame of the upper fixing base 11 and the lower fixing base 12. The number of the wheel supports 3 is four, two pairs of the four wheel supports 3 are connected with the second connecting parts 15 formed at the two ends of the upper fixing seat 11 and the lower fixing seat 12 in an inserting mode, and wheels 8 are installed on the wheel supports 3. The push rod 4 is formed by sequentially inserting and assembling a left lower pipe 41, a left middle pipe 42, a left upper pipe 43, a left transverse pipe 44, a right transverse pipe 45, a right upper pipe 46, a right middle pipe 47 and a right lower pipe 48 to form an inverted U-shaped structure, and the left lower pipe 41 and the right lower pipe 48 are respectively inserted into a third inserting portion 16 formed by the upper fixing seat 11 and the lower fixing seat 12 on the rear side of the frame.

The first plug-in part 14, the second plug-in part 15 and the third plug-in part 16 all have insertion holes penetrating through the fixing base 1. The elastic element further comprises a first cord seat 71, a second cord seat 72, a third cord seat 73, a fourth cord seat 74 and a fifth cord seat 75. The first rope seat 71 and the second rope seat 72 are respectively fixed at one end of the seat supporting rod 2 and one end of the wheel bracket 3, which are opposite to the fixed seat 1. A third rope socket 73 and a fourth rope socket (not shown in the figure) are respectively fixed at one ends of the first inserting part 14 and the second inserting part 15, which are back to the seat supporting rod 2 and the wheel bracket 3; two fifth rope seats 75 are respectively fixed at one end of the third insertion part 16 facing away from the push rod 4. The elastic cords 7 are connected between the first cord seat 71 and the third cord seat 73, between the second cord seat 72 and the fourth cord seat, and between the two fifth cord seats 75, respectively.

Borrow by above-mentioned structure, each partial structure of this children's shallow frame all can be disassembled, and concatenate through elasticity rope 7 and each rope socket, can not only be at seat bracing piece 2, wheel support 3 and push rod 4 and fixing base 1 grafting equipment back, with seat bracing piece 2, wheel support 3 and push rod 4 keep on fixing base 1, can also be at seat bracing piece 2, wheel support 3 and push rod 4 and fixing base 1 after disassembling, make still keep as scattered integrative structural style that nevertheless connects through elasticity rope 7 between seat bracing piece 2, wheel support 3 and push rod 4 and the fixing base 1, thereby be convenient for assemble once more.
