When the first locking piece 53 is located in the first accommodating cavity 510 and the second accommodating cavity at the same time, the inner walls of the first accommodating cavity 510 and the second accommodating cavity prevent the first joint 51 from rotating relative to the second joint 52. The first rotating member 54 is sleeved on the first rotating shaft 511 and is fixed to the second joint 52.

With continued reference to fig. 1 to 3, the unlocking member 6 includes a first unlocking component, the first unlocking component selects an unlocking button, the unlocking member 6 is mounted on the outer side of the second joint 52 and abuts against the first locking member 53, when the user presses the unlocking button 6 in a transverse direction (towards the second joint), the first locking member 53 is separated from the second accommodating cavity, the inner wall of the second accommodating cavity no longer blocks the second joint 52 from rotating relative to the first joint 51, that is, the first push rod 21 connected to the first joint 51 can rotate relative to the second push rod connected to the second joint 52, that is, the unlocking member 6 is used for driving the first locking member to switch from the locking state to the unlocking state. In other embodiments, the unlocking member 6 may be other unlocking structures, such as a pull cord; the position of the unlocking member 6 may also be changed, for example, provided on the first push rod 21.

The second latch assembly 7 is connected to the second push rod 22 and the third push rod 23, and has a locked state preventing the second push rod from rotating relative to the third push rod and an unlocked state allowing the second push rod to rotate relative to the third push rod. The second locking assembly 7 includes a third joint 71 connected to the second push rod 22, a fourth joint 72 connected to the third push rod 23, a second locking member 73 and a third rotating member 74 disposed in a space enclosed by the third joint 71 and the fourth joint 72. The third joint includes a third receiving cavity 710, a second rotating shaft 711 (i.e., the rotating shaft connecting the second push rod 22 and the third push rod 23) extending from the third receiving cavity toward the fourth joint, and a guiding structure 712. The second latch assembly 7 has a structure substantially identical to that of the first latch assembly 5. The second rotating member 74 is sleeved on the second rotating shaft 711 and can rotate relative to the second rotating shaft 711 with the fourth joint. When the second rotating member 74 rotates relative to the second rotating shaft 711, due to the guiding surface of the guiding structure 712 and the third joint, the second rotating member 74 generates a lateral displacement while rotating, and laterally abuts against the second locking member 73, so that the second locking member 73 is separated from the third accommodating cavity 710, and the third joint 71 connected with the second push rod 2 is allowed to rotate relative to the fourth joint 72 connected with the third push rod, i.e. the second locking member is driven to switch from the locking state to the unlocking state, thereby unlocking the whole vehicle frame.

In other embodiments, the second latch assembly may also directly lock the third push rod 43 (or push rod assembly 4) and the armrest assembly 8 from rotating relative to each other; while the foregoing embodiment can be considered as a structure in which the second push rod 22, the third push rod 23, the armrest assembly 8 and the seat link 42 are stabilized by locking the second push rod 42 and the third push rod 43, the third push rod 43 (or the push rod assembly 4) and the armrest assembly 8 are indirectly locked. Thus, the second latch assembly 7 can be said to have a locked state preventing rotation of the armrest assembly 8 relative to the push rod assembly 2 and an unlocked state allowing rotation of the armrest assembly 8 relative to the push rod assembly 2.

The stroller further comprises a linkage element 9, in this embodiment, the linkage element 9 selects a pull rope, the linkage element 9 connects the first rotating member 54 and the second rotating member 74, when the user presses the unlocking member 6, the first locking assembly 5 is unlocked, and the second joint 52 is allowed to rotate relative to the first joint 51, that is, the first push rod 21 is allowed to rotate relative to the second push rod 22; the second joint 52 drives the first rotating member 54 to rotate at the same time, the first rotating member 54 drives the second rotating member 74 to rotate through the linkage element 9, and the second rotating member 74 unlocks the second locking assembly 7 when driving the fourth joint 72 to rotate relative to the third joint 73, so that the third push rod 23 is allowed to rotate relative to the second push rod 22, and unlocking of the second locking assembly 7 is achieved. That is, the unlocking of the entire vehicle frame can be achieved by pressing the unlocking member 6. The unlocking piece 6 drives the second locking component 7 to switch from the locking state to the unlocking state through the first locking component 5 and the linkage piece 9. Unlocking is achieved in a linkage mode, folding steps of the child stroller are simplified, and better user experience is brought. Of course, in other embodiments, a second unlocking member for driving the second latch assembly may be separately provided instead of the linkage element, that is, the unlocking member includes a first unlocking member and a second unlocking member.

Referring to fig. 4, when the user presses the unlocking member 7 and simultaneously turns over the first push rod 21, the first push rod 21 is folded relative to the second push rod 22; referring to fig. 5, since the second unlocking component is unlocked after being driven by the linkage element 9, the second push rod 22 is allowed to fold relative to the third push rod 23, and meanwhile, the overturning piece 30 overturns to drive the first link 31, the second link 32, the third link 33, the first bracket 11 and the second bracket 12 to rotate; as shown in fig. 6, the fully folded stroller is characterized in that the first push rod 21 is abutted against the second push rod 22, the second push rod 22 is abutted against the third push rod 23, and the third push rod 23 is located between the two second sections 122, wherein the folded length of the push rod assembly 2 is only one third of that of the folded stroller, and the folded size of the second bracket 12 is reduced, so that the folded size of the stroller is further reduced, and the stroller is convenient to carry or store.

Referring to fig. 7, in another embodiment, the stroller is substantially identical in structure to the previous embodiment, except for the link assembly. The link assembly 3 of the present embodiment includes a first link 31 pivotally connected to the first bracket 11, a second link 32 pivotally connected to the second bracket 12, and a turnover mechanism 35 pivotally connected to the first link 31 and the second link 32, wherein the turnover mechanism 35 is turned when the stroller is folded.
