[0059] Optionally, in the present embodiment, as shown in Figure 2 and Figure 1 As shown, the rear support 23 comprises a rear support body 231 and a first connecting rod 232, wherein the first connecting rod 232 is in an arc shape, the first connecting rod 232 is fixedly connected with the end of the rear support body 231, so that the rear support 23 is in a T-shaped structure, the first end of the first connecting rod 232 is rotatably connected with the second end of the lower pushing rod 22 through the second rotating shaft 52, the second end of the first connecting rod 232 is rotatably connected with the front support 24 through the third rotating shaft 53, the seat assembly 1 is rotatably connected with the first connecting rod 232 through the fourth rotating shaft 54, and the rotatable connection position of the seat assembly 1 and the first connecting rod 232 is between the first end of the first connecting rod 232 and the second end of the first connecting rod 232. The structural design of the rear support 23 makes the folding of the frame assembly 2 more smooth. In addition, by arranging the first connecting rod 232, the gravity center of the frame assembly 2 is lowered, so that the frame assembly 2 is more stable and reliable. It should be noted that in the present embodiment, when the frame assembly 2 is in the unfolded state, the front support 24 is arranged at an angle with the pushing rod. In other embodiments, when the frame assembly 2 is in the unfolded state, the front support 24, the first connecting rod 232 and the pushing rod can also extend in the same direction.
[0060] Optionally, in other embodiments, the front support 24 and the second end of the lower pushing rod 22 are rotatably connected with the rear support 23 through the same rotating shaft. This arrangement not only reduces the number of rotating shafts, making the structure more simple, but also further reduces the size of the frame assembly 2 after folding.
[0061] In the present embodiment, as shown in Figure 2 and Figure 1As shown in FIG. 1, the linkage assembly 3 comprises a traction rod 31 and a support rod 32, wherein a first end of the traction rod 31 is rotatably connected with the support swing rod 25 through a seventh rotating shaft 57, a second end of the traction rod 31 is rotatably connected with the front support 24 through an eighth rotating shaft 58, a first end of the support rod 32 is rotatably connected with a middle part of the traction rod 31 through a ninth rotating shaft 59, and a second end of the support rod 32 is rotatably connected with the seat assembly 1 through a tenth rotating shaft 50. During the movement of the frame assembly 2 from the unfolded state to the folded state, the support swing rod 25 can pull the traction rod 31 to move, so that the traction rod 31 pulls the seat assembly 1 and the frame assembly 2 to be relatively close through the support rod 32. In addition, by arranging the support rod 32, reliable support for the seat assembly 1 is achieved. It should be noted that in the embodiment, the tenth rotating shaft 50 is located in front of the fourth rotating shaft 54, and the ninth rotating shaft 59 is located behind the tenth rotating shaft 50.
[0062] In the embodiment, as shown in FIG. 1, Figure 5 and Figure 1 the seat assembly 1 comprises a seat rod 11 and a backrest 12, wherein the seat rod 11 is rotatably connected with the first connecting rod 232 through the fourth rotating shaft 54, and the second end of the support rod 32 is rotatably connected with the seat rod 11 through the tenth rotating shaft 50, and the backrest 12 is rotatably connected with the seat rod 11. As shown in FIG. 1, Figure 1 when the frame assembly 2 is in the unfolded state, the seat rod 11 is in a horizontal placement state, and the backrest 12 is located at the upper part of the seat rod 11, and when the frame assembly 2 is in the folded state, the backrest 12 can be folded relative to the seat rod 11, so that the folding size of the entire folding stroller is smaller.
[0063] Optionally, in the embodiment, the seat rod 11 is in a U shape, the seat rod 11 comprises a connecting horizontal rod 111 and two side wall rods 112, the two side wall rods 112 are oppositely and spacedly arranged and are both connected with the connecting horizontal rod 111, the side wall rod 112 is rotatably connected with the first connecting rod 232 through the fourth rotating shaft 54, the second end of the support rod 32 is rotatably connected with the side wall rod 112 through the tenth rotating shaft 50, and a first end of the backrest 12 is rotatably connected with the connecting horizontal rod 111. As shown in FIG. 1, Figure 5 when the frame assembly 2 is in the unfolded state, the connecting horizontal rod 111 and the two side wall rods 112 are all in the same horizontal plane, and the first end of the backrest 12 is located at the lower part of the second end of the backrest 12; as shown in FIG. 1, Figures 1-5As shown, when the frame assembly 2 is in the folded state, the connecting cross bar 111 is located at the upper portion of the two side wall bars 112, the first end portion of the backrest 12 is located at the upper portion of the second end portion of the backrest 12, and the position of the bottom of the frame assembly 2 is lower than the position of the second end portion of the backrest 12. When the frame assembly 2 is in the folded state, the position of the connecting cross bar 111 is not higher than the position of the top of the frame assembly 2. The above arrangement makes the connecting cross bar 111 of the seat rod 11 fold upward when the entire folding stroller is folded, and the backrest 12 folds downward relative to the connecting cross bar 111, without breaking the backrest 12 to achieve the folding operation of the entire folding stroller, and avoids the backrest 12 of the folded folding stroller from contacting the ground, so that the structure of the folded folding stroller is more reliable.
[0064] It should be noted that when the entire folding stroller is folded, the rear support 23 and the front support 24 can be relatively locked by the locking device, and the lower push rod member 22 and the rear support 23 can be relatively locked by the locking device to ensure the stability of the structure of the folded folding stroller and facilitate the transportation of the folding stroller. In this embodiment, the locking device can be a strap or a rope, and the specific form of the locking device is not limited in this embodiment. When the folding stroller is in normal use, the relative positions of the upper push rod member 21 and the lower push rod member 22 can be locked by the locking device, and the relative positions of the lower push rod member 22 and the rear support 23 can be locked to ensure the stability and reliability of the structure of the folding stroller when it is in normal use. Since the specific form of the locking device belongs to the prior art, it will not be described here.
[0065] In order to facilitate the understanding of the folding stroller disclosed in this embodiment, the folding stroller will be described in detail below. The specific folding process of the folding stroller will be described:
[0066] First, fold the upper push rod member 21 so that the upper push rod member 21 and the lower push rod member 22 are relatively close to each other. At this time, the support swing rod 25 can pull the traction rod 31 to move, so that the traction rod 31 pulls the seat assembly 1 and the frame assembly 2 relative to each other through the support rod 32, and at this time the traction rod 31 can make the rear support 23 and the front support 24 relative to each other. At the same time, the lower push rod member 22 and the rear support 23 can be relatively close to each other, thereby completing the folding process of the entire folding stroller. It should be noted that the unfolding process of the folding stroller is the reverse process of folding the folding stroller, which will not be described here.
