[0044] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0045] like Figure 1-11 As shown, this utility model includes a stroller that can be switched between a folded state and an unfolded state. It includes a rear leg post 1, a front leg post 2, a push rod assembly 3, a drive rod 4, a front connecting rod 5, and a seat frame 6. The upper end of the front leg post 2 is rotatably connected to the upper end of the rear leg post 1. The push rod assembly 3 includes a handle 30 and a lower push rod 31. A push rod joint 32 is provided between the handle 30 and the lower push rod 31 to lock the handle 30 in unfolded position relative to the lower push rod 31. The lower end of the lower push rod 31 is positioned relative to the upper end of the rear leg post 1. The handlebar 30 is rotatably connected to the handlebar 30 and is also provided with a push rod unlocking assembly 33 for unlocking the push rod joint 32 in the locked state. The upper end of the drive rod 4 is hinged to the lower end of the handlebar 30, the lower part of the drive rod 4 is hinged to the upper part of the rear foot rod 1, one end of the front connecting rod 5 is hinged to the lower end of the drive rod 4, the other end of the front connecting rod 5 is hinged to the front foot rod 2, the rear part of the seat frame 6 is hinged to the drive rod 4, the front side of the seat frame 6 is hinged to the seat frame connecting rod 7, and the other end of the seat frame connecting rod 7 is directly or indirectly hinged to the upper part of the rear foot rod 1.

[0046] In this embodiment, when folding the stroller, the push rod unlocking assembly 33 unlocks the push rod joint 32 from its locked state. At this time, the handle 30 can be pushed down to rotate the rod 31 and fold the stroller. Simultaneously, the push rod 31 and the drive rod 4 can fold towards the rear leg 1, and the front leg 2, under the linkage of the front connecting rod 5, also folds towards the rear leg 1. Since the rear of the seat frame 6 is hinged to the drive rod 4, the seat frame 6 also folds towards the rear leg 1 under the drive rod 4. This application enables one-click folding after unlocking the push rod joint 32 by the push rod unlocking assembly 33, making the folding operation simple and quick. In addition, the seat frame connecting rod 7 of this application is hinged to the front side of the seat frame 6, which can more effectively support the seat frame 6 after it is unfolded, making the seat frame 6 more stable.

[0047] It is understood that in this embodiment, the drive rod 4, the front connecting rod 5, the front foot rod 2, and the lower push rod 31 constitute a four-bar linkage. Therefore, after the push rod unlocking assembly 33 unlocks the locked state of the push rod joint 32, the lower push rod 31, the front foot rod 2, and the drive rod 4 can fold towards the rear foot rod 1. Similarly, the seat frame 6, the seat frame connecting rod 7, the drive rod 4, and the rear foot rod 1 also form a four-bar linkage. After the push rod unlocking assembly 33 unlocks the locked state of the push rod joint 32, the drive rod 4 can fold towards the rear foot rod 1, which can simultaneously drive the seat frame 6 to fold towards the rear foot rod 1.

[0048] It should be noted that the push rod joint 32 and the push rod unlocking component 33 are conventional technologies in this application, and will not be described in detail here.

[0049] In addition, to make the entire frame more stable, a lower reinforcing rod 22 is provided between the front foot rods 2. The front connecting rod 5 is hinged to the lower reinforcing rod 22. In this way, the front connecting rod 5 can be indirectly hinged to the front foot rod 2 without being directly connected to the front foot rod 2, thereby avoiding damage to the front foot rod 2.

The rear of the armrest 8 is hinged to the drive rod 4, and the rear end of the armrest 8 is hinged to an armrest connecting rod 9. The lower end of the armrest connecting rod 9 is hinged to the rear end of the seat frame 6. In this embodiment, both the armrest 8 and the rear of the seat frame 6 are hinged relative to the drive rod 4. The hinge point between the armrest 8 and the drive rod 4 is located above the hinge point between the seat frame 6 and the drive rod 4. The rear end of the seat frame 6 is hinged to the rear end of the armrest 8 via the armrest connecting rod 9. When folding the stroller, the armrest 8 is pulled towards the seat frame 6 by the action of the seat frame 6, and simultaneously folds towards the rear footrest 1 by the action of the drive rod 4, making it easier and more convenient for the user to fold the stroller.

[0051] like Figure 10 and Figure 11 As shown, as a further embodiment, the rear of the seat frame 6 is provided with a seat frame joint block 60 hinged to the fixed seat 40. The seat frame joint block 60 extends rearward and downward to form a seat frame extension block 61. The rear of the armrest bar 8 is provided with an armrest joint block 80 hinged to the drive rod 4. The armrest joint block 80 extends rearward and downward to form an armrest extension portion 81. The upper end of the armrest connecting rod 9 is hinged to the armrest extension portion 81, and the lower end is hinged to the armrest joint block 80. In this embodiment, by providing a seat frame joint block 60 at the rear of the seat frame 6 and an armrest joint block 80 at the rear of the armrest bar 8, production can be facilitated and manufacturing difficulty reduced. By providing the armrest extension portion 81 and the seat frame extension portion 61, the seat frame 6 and the armrest 8 can have more room to move during the folding process, avoiding interference with other components and making the folding process smoother.

[0052] like Figure 5 and Figure 8 As shown, as a further embodiment, the drive rod 4 is provided with a fixed seat 40, and the rear part of the seat frame 6 is hinged to the fixed seat 40. In this embodiment, an upper reinforcing rod 45 is provided between the two drive rods 4, and the fixed seat 40 is provided on the upper reinforcing rod 45. By providing the upper reinforcing rod 45, the entire frame can be made more stable, and since the rear part of the seat frame 6 is hinged to the fixed seat 40, the seat frame 6 can also be made more stable during use.

[0054] like Figures 5 to 9As shown, as a further embodiment, the fixed base 40 is formed with an adjustment groove 41. The lower part of the backrest rod 100 extends into the adjustment groove 41 and is hinged to the opening of the adjustment groove 41. The adjustment assembly 101 includes an adjustment fixing rod 102 disposed at the lower end of the backrest rod 100 and telescopically cooperating with it, and an elastic member 103 disposed in the backrest rod 100 for driving the end of the adjustment fixing rod 102 to always maintain a tendency to extend towards the adjustment groove 41. The side wall of the adjustment groove 41 is provided with a plurality of slots 410 that can engage with the end of the adjustment fixing rod 102. In this embodiment, the elastic element 103 is a spring. The adjusting rod 102 has a groove (not shown in the figure) to accommodate the spring. The lower part of the backrest rod 100 is provided with a pin (not shown in the figure) that passes through the upper part of the groove. The groove has a movable hole (not shown in the figure) for the adjusting rod 102 to move up and down at the pin. The lower end of the spring abuts against the bottom of the groove, and the upper end abuts against the pin. The adjusting rod 102 will be kept extended from the bottom of the backrest rod 100 and engaged with the slot 410 under the action of the spring. The backrest rod 100 is also provided with a backrest unlocking component 104. Operating the backrest unlocking component 104 can drive the adjusting rod 102 to overcome the elastic force of the elastic element 103 and retract into the backrest rod 100, so that its end is disengaged from the slot 410, thereby allowing the adjusting rod 102 to engage with the corresponding slot 410 to adjust the angle of the backrest rod 100. The backrest unlocking component 104 is movably connected to the backrest rod 100. The backrest unlocking component 104 is connected to the adjusting fixing rod 102 via a steel cable. When the backrest rod 100 needs adjustment, the steel cable is pulled by the backrest unlocking component 104, causing the adjusting fixing rod 102 to disengage from the current slot 410. Then, the backrest rod 100 is rotated and subsequently engaged with the corresponding slot 410, thus completing the angle adjustment of the backrest rod 100. It should be noted that the backrest unlocking component 104 is conventional technology in the art, and therefore will not be described in detail in this embodiment.

[0055] like Figures 1 to 5 As shown, as a further embodiment, the upper end of the rear leg bar 1 is provided with a rear leg bar joint block 10, the upper end of the front leg bar 2 is provided with a front leg bar joint block 21 hinged to the rear leg bar joint block 10, and the lower end of the lower push rod 31 is provided with a lower push rod joint block 310 hinged to the rear leg bar joint block 10. The rear leg bar joint block 10, the front leg bar joint block 21, and the lower push rod joint block 310 form a frame joint 300, and the seat frame connecting rod 7 is hinged to the rear leg bar joint block 10. In this embodiment, by setting the front leg bar joint block 21, the rear leg bar joint block 10, and the lower push rod joint block 310 to form the frame joint 300, assembly and production can be facilitated.

[0056] like Figures 1 to 5As shown, as a further embodiment, the rear leg joint block 10 extends forward and downward to form an extension 11, and the seat frame connecting rod 7 is hinged to the extension 11. By setting the extension 11, the extension moves the hinge point of 11 forward and downward, so that the seat frame connecting rod 7 has more room to move during the folding process, avoiding interference with other components and making the folding process smoother.

[0057] like Figure 6 and Figure 7 As shown, as a further embodiment, to facilitate the user's placement of items, the lower end of the drive rod 4 is directly or indirectly hinged to a storage frame 12 extending towards the rear foot rod 1. The lower end of the drive rod 4 is provided with a limiting member 42, which is configured to restrict the storage frame 12 to the unfolded position when the stroller is in the unfolded state, and to allow the storage frame 12 to fold towards the drive rod 4 when the stroller is folded. In this embodiment, by setting the storage frame 12 to a hinged manner, it can also be rotated to fold during the stroller folding process, and unfolds naturally under the action of gravity.

[0058] like Figure 6 and Figure 7 As shown, as a further embodiment, the lower part of the drive rod 4 is provided with a connecting seat 43, and the connecting seat 43 is provided with a hinge groove 44.
