[0027] The present invention will be further described below in conjunction with the accompanying drawings:

[0028] like Figures 1 to 4 ,as well as Figure 9As shown, a children's stroller includes a front support frame 1, the front support frame 1 is connected to a steering assembly 2, the lower end of the steering assembly 2 is connected to a front wheel 3, the front wheel 3 is connected to a foot pedal 4, the lower side of the front support frame 1 is provided with a first connecting position 5, the upper side of the front support frame 1 is provided with a second connecting position 6, the children's stroller also includes a support frame 7 that can be switched between the first connecting position 5 and the second connecting position 6 and connected to the front support frame 1, the support frame 7 is connected to a bottom support frame 8 that can rotate relative to the support frame 8, the rear side of the bottom support frame 8 is provided with a rear wheel 9, the support frame 7 or the bottom support frame 8 is also connected to a seat frame 10 that can be both unfolded and folded, and when the support frame 7 is connected to the first connecting position 5, the angle A between the support frame 7 and the bottom support frame 8 is smaller than the angle B between the support frame 7 and the bottom support frame 8 when the support frame 7 is connected to the second connecting position 6. A first connection position 5 is provided on the lower side of the front support frame 1, and a second connection position 6 is provided on the upper side. When the support frame 7 is connected to the first connection position 5, the seat frame 10 is folded, and the baby stroller can be used as a scooter. The child steps on the bottom support frame with one foot and pushes the ground with the other foot to slide and play. When the support frame 7 is connected to the second connection position 6, the support frame 7 is raised, and the bottom support frame 8 rotates relative to the support frame 7. The angle between the bottom support frame 8 and the support frame 7 becomes larger, ensuring that the unfolded seat frame 10 has a sufficient height. The rear wheel 9 is still supported on the ground. The child can sit on the seat frame 10 and step on the pedals 4 with both feet to use the baby stroller as a bicycle and play. Therefore, the position where the support frame 7 is connected to the front support frame 1 can be switched between the first connection position 5 and the second connection position 6 to change the use state of the baby stroller. It is easy to operate and makes the product multifunctional. Figure 9 As shown, when the support frame 7 is connected to the first connection position 5, the seat frame 10 can be folded, and the bottom support frame 8 can also be folded by rotating it relative to the support frame 7, so that the entire children's stroller can be folded, reducing the occupied space and facilitating storage and carrying.

[0029] like Figures 1 to 4 As shown, the seat frame 10 is rotatably connected to the position where the support frame 7 and the bottom support frame 8 are connected, so that the entire baby stroller has a compact structure and is flexible to unfold and fold.

[0030] like Figures 1 to 4 As shown, the upper end of the support frame 7 is slidably connected to the front support frame 1 and can be switched between the first connection position 5 and the second connection position 6. The lower end of the support frame 7 is rotatably connected to the bottom support frame 8 via a connecting joint 11. The support frame 7 is slidably connected to the front support frame 1. Therefore, when changing the use state of the baby stroller, it is only necessary to slide the support frame 7 up and down along the front support frame 1 and then rotate the bottom support frame 8 relative to the support frame 7. The operation is very convenient and smooth.

[0031] like Figure 1As shown in FIG6 , the support frame 7 includes a sliding sleeve 71 that is mounted on the front support frame 1 and can slide up and down. The sliding sleeve 71 is provided with an inclined support plate 72, and the bottom support frame 8 is connected to the lower end of the support plate 72. As a result, the entire children's stroller has a compact structure, can be switched between different use states smoothly and flexibly, and has a small volume when folded, making it easy to store and carry.

[0032] like Figure 2 、 Figure 4 As shown in Figures 5 and 6, the first connecting position 5 and the second connecting position 6 are recessed holes arranged on the front support frame 1, and the sliding sleeve 71 is provided with a locking pin 121 which can move laterally therein and can engage with or disengage from the recessed hole, and the locking pin 121 is provided with an operating part 122 exposed to the support frame 7, and a first reset spring 123 which can push the locking pin 121 to reset is also provided between the support frame 7 and the locking pin 121, and a slot 124 is provided on the locking pin 121, and a sliding pin 125 which can slide therein and engage with or disengage from the slot 124 and be exposed to the support frame 7 is provided in the support frame 7, and a second reset spring 126 is also provided between the support frame 7 and the sliding pin 125. When the children's car is used as a scooter, the locking pin 121 is horizontally inserted into the recessed hole of the first connecting position 5, and the sliding pin 125 is inserted into the slot 124 on the locking pin 121 to avoid accidental contact with the operating part 122 and mislocking. When the children's car needs to be used as a bicycle, it is only necessary to pull the sliding pin 125 and then pull the operating part 122 to withdraw the locking pin 121 from the first connecting position 5, and then slide the sliding sleeve 71 upward. When the sliding reaches the set position, the locking pin 121 is horizontally inserted into the recessed hole of the second connecting position 6, and the sliding pin 125 is snapped into the slot 124, thereby realizing the locking of the support frame 7 and the front support frame 1. The operation is very convenient and quick.

[0033] like Figure 1 As shown in FIG5 , the footrest 4 is detachably connected to the front wheel 3, and the support frame 7 is provided with a receiving slot 73 for storing the footrest 4. When the child stroller is used as a scooter, the seat frame 10 is folded onto the support frame 7, enclosing the footrest 4 within the receiving slot 73. When the child stroller is used as a scooter or folded for storage, the footrest 4 can be stored in the receiving slot 73 and enclosed by the folded seat frame 10, preventing the footrest 4 from idling while the scooter is sliding, which would affect user comfort, while also ensuring that the child stroller takes up minimal space when stored.

[0034] As shown in Figure 6 to Figure 8As shown, the connecting joint 11 includes a first joint seat 111 arranged at the lower end of the support frame 7 and a second joint seat 113 arranged at the front end of the bottom support frame 8 and rotatably connected to the first joint seat 111 around a first pin shaft 112. The first joint seat 111 and the second joint seat 113 are both provided with tooth grooves 114 along the circumferential direction. The space enclosed by the first joint seat 111 and the second joint seat 113 is provided with a gear 115 that can move axially and engage with the tooth grooves 114 on the first joint seat 111 and the second joint seat 113 at the same time. A third reset spring 116 is also provided between the gear 115 and the first joint seat 111. The second joint seat 113 is provided with an exposed button 117 that can push the gear 115 to disengage the gear 115 from the tooth groove 114 on the second joint seat 113. When the bottom support frame 8 needs to be rotated relative to the support frame 7, the button 117 is pressed to disengage the gear 115 from the tooth groove 114 on the second joint seat 113. Then, the bottom support frame 8 can be rotated. When it is rotated to the set position, the button 117 is released, and the third return spring 116 pushes the gear 115 to return to its original position. The gear 115 is then simultaneously engaged with the tooth groove 114 on the first joint seat 111 and the second joint seat 113, and the locking is achieved again. The whole operation is very convenient and fast.

[0035] As shown in Figure 6 to Figure 8As shown, the seat frame 10 is provided with a hinge seat 131 that can rotate around the first pin shaft 112, and the hinge seat 131 is provided with an arc groove 132. The first joint seat 111 is provided with a second pin shaft 133 parallel to the first pin shaft 112 and passing through the arc groove 132. The first joint seat 111 is also provided with two positioning holes 134 along the circumferential direction. The hinge seat 131 is provided with a positioning pin 135 that can move axially and engage or disengage with the positioning hole 134. The positioning pin 135 has an arc-shaped end, and a fourth return spring (not marked in the figure) is provided between the positioning pin 135 and the hinge seat 131. When the seat frame 10 is folded onto the support frame 7, the arc-shaped end of the positioning pin 135 is engaged in one of the positioning holes 134. When the seat frame 10 is rotated relative to the support frame 7 and unfolded, the arc-shaped end of the positioning pin 135 is engaged in the other positioning hole 134. Because the positioning pin 135 has an arc-shaped end, when the seat frame 10 needs to be expanded or collapsed, the seat frame 10 can be simply pulled with force to disengage the seat frame positioning pin 135 from one positioning hole 134. When the seat frame 10 is rotated to the set position, the positioning pin 135 aligns with the other positioning hole 134, and the fourth return spring pushes the positioning pin 135 axially to engage with the other positioning hole 134, thereby positioning the seat frame 10. The cooperation between the arc-shaped groove 132 and the second pin 133 serves as a guide, ensuring that the seat frame 10 can be expanded or collapsed very smoothly. More importantly, the second pin 133 also supports the seat frame 10 when it is expanded, ensuring that the seat frame 10 has sufficient load-bearing capacity.

[0036] like Figure 1 , Figure 5 and Figure 9 As shown, the steering assembly 2 includes a steering rod 21 that can rotate within the front support frame 1. The front wheel 3 is connected to the lower end of the steering rod 21. The steering rod 21 is provided with a steering handle 22 that can be extended and retracted therein. A positioning structure 14 is provided between the steering handle 22 and the steering rod 21 to position the two. When the stroller is folded, the steering handle 22 can be retracted into the steering rod 21 by operating the positioning structure 14, thereby further reducing the size of the folded stroller, reducing storage space, and making it easier to store and carry. The positioning structure 14 can adopt a conventional snap-fit structure and will not be described in detail here.
