In this embodiment, two lock bars 61b are provided and are both disposed at the lower portion of the slider 61a, and two lock grooves 62a are provided and correspond to the positions of the two lock bars 61b one by one. The upper portion of the rear bracket 2 is further provided with an arc-shaped slot 21 which is communicated with the lock slot 62a and can provide sliding guide for the lock rod 61b, the arc-shaped slot 21 takes the first shaft b as a rotation center line, and the lock slot 62a is located at the outer side of the arc-shaped slot 21. The locking member 61 has a locking position and an unlocking position on the lower push rod 52, and when the locking member 61 is in the locking position, the two locking rods 61b are inserted into the locking grooves 62a in a one-to-one corresponding fit manner, and at this time, the first locking mechanism 6 is in a locking state; when the locking member 61 is in the unlocking position, the lock lever 61b is disengaged from the lock groove 62a and is located in the arc-shaped groove 21 in a sliding fit, and at this time, the first locking mechanism 6 is in the unlocked state.
The linkage mechanism 7 at least has a linkage member 71, and during the folding process of the upper push rod 51 relative to the lower push rod 52, the linkage member 71 and the locking member 61 cooperate with each other to enable the locking member 61 to move from the locking position to the unlocking position. Specifically, in the present embodiment, the locking position of the locking member 61 is located above the unlocking position, the link 71 is disposed in the rod cavity of the lower push rod 52 so as to be relatively slidable in the up-down direction, the lower portion of the upper push rod 51 has a cam surface 51a, and the link 71 abuts between the cam surface 51a and the locking member 61 in the up-down direction. In the process that the upper push rod 51 is folded relative to the lower push rod 52, the upper push rod 51 rotates counterclockwise about the second axis c, the upper push rod 51 drives the cam surface 51a to rotate, the cam surface 51a further pushes the link 71 to slide downward along the length extension direction of the lower push rod 52, the slider 61a is driven to slide downward, and the lock rod 61b arranged at the lower part of the slider 61a gradually slides from the lock slot 62a into the arc-shaped slot 21.
An elastic member (not shown) for providing a force required to move the slider 61a toward the locking position is further provided between the base bracket 101 and the slider 61 a. In this embodiment, during the process of converting the push rod frame 102 from the retracted state to the open state, when the locking rod 61b slides to the joint of the arc-shaped slot 21 and the locking slot 62a, the elastic member (not shown) releases the elastic force to drive the locking rod 61b to move upward, and the locking rod 61b is separated from the arc-shaped slot 21 and is fittingly inserted into the locking slot 62a.

The following description will exemplarily describe the manner of switching between the forward use state and the backward use state of the seat device of the stroller.
When the child stroller is in a forward use state, as shown in fig. 1 to 3, the push rod frame 102 is in an open state, the upper push rod 51 and the lower push rod 52 both extend obliquely upward from front to back and extend along substantially the same length direction, the handle 53 is disposed upward, the first locking mechanism is in a locked state, the lock lever 61b is fittingly inserted into the lock groove 62a, and the seat device 200 is disposed forward in a forward use state.
When it is required to convert the seat assembly 200 of the stroller into a backward use state, referring to fig. 4 to 8, the grip 53 is pushed forward, so that the upper push rod 51 rotates counterclockwise about the second axis c, and the upper push rod 51 and the lower push rod 52 are folded relatively; the forward rotation of the upper push rod 51 drives the cam surface 51a to rotate, the cam surface 51a pushes the link member 71 to slide downwards along the length extension direction of the lower push rod 52, the link member 71 drives the slide block 61a to slide downwards, and the lock rod 61b is separated from the lock groove 62a and is positioned in the arc-shaped groove 21 in sliding fit, so that the first locking mechanism 6 is unlocked. Thereafter, the grip 53 is pushed downward, and the lower push rod 52 rotates clockwise downward around the first axis b until the lower push rod 52 and the upper push rod 51 are sequentially gathered in the front-rear direction behind the bottom bracket 101, at which time the grip 53 is disposed upward. Synchronously, the lock lever 61b slides downward in the lengthwise extending direction of the arc-shaped groove 21.
Thereafter, the locking between the base 201 and the seat frame 3 by the third locking mechanism (not shown in the figure) is released, and the seat device 200 is pushed so that the seat device 200 is rotated around the rotation center line a to face rearward, so that the seat device 200 is shifted to the backward use state.
Subsequently, the grip 53 is pulled upward, the upper push rod 51 rotates clockwise rearward about the second axis c, the lower push rod 52 rotates counterclockwise upward about the first axis b, the upper push rod 51 opens relative to the lower push rod 52, the lower push rod 52 moves away relative to the rear bracket 2, and the push rod bracket 102 is switched from the retracted state to the open state; meanwhile, the locking rod 61b slides upwards along the length extending direction of the arc-shaped groove 21 until the locking rod 61b slides to the joint of the arc-shaped groove 21 and the locking groove 62a, the elastic member (not shown in the figure) releases the elastic force to drive the locking rod 61b to move upwards, the locking rod 61b is separated from the arc-shaped groove 21 and is cooperatively inserted in the locking groove 62a, at this time, the first locking mechanism 6 is in the locking state again, and the push rod frame 102 is unfolded again relative to the bottom bracket 101 to be in the opening state.
Example two
Referring to fig. 9 to fig. 11, the difference between the present embodiment and the first embodiment is mainly that: in the present embodiment, the upper push rod 51 is relatively slidably inserted into the lower push rod 52, the link member 71 is fixedly disposed at the lower end portion of the upper push rod 51 or integrally formed at the lower end portion of the upper push rod 51, and the link member 71 is located above the locking member 6.
Specifically, when the push rod frame 102 is in the open state, the upper push rod 51 and the lower push rod 52 both extend obliquely from front to back and upward and extend in substantially the same longitudinal direction, and the grip 53 is disposed upward.
In the process of converting the push rod frame 102 from the open state to the retracted state, the handle 53 is pushed downwards, the upper push rod 51 slides downwards along the length extension direction of the lower push rod 52, and the linkage piece 71 arranged on the lower end part of the upper push rod 51 is driven to slide downwards until the linkage piece 71 abuts against the sliding piece 61 a; when the grip 53 is further pushed downward, the link 71 pushes the slide member 61a to slide downward along the length of the lower push rod 52, and the lock lever 61b is disengaged from the lock groove 62a and is fitted in the arc-shaped groove 21, and the first locking mechanism 6 is unlocked. The lower rod 52 rotates clockwise downward around the first axis c until the lower rod 52 and the upper rod 51 are sequentially folded back and forth behind the bottom bracket 101, and the grip 53 is disposed downward, at which time the push rod holder 102 is in the folded state.
Compared with the second embodiment, in the first embodiment, the grip 53 is disposed upward when the push rod frame 102 is in the open state and the retracted state, so that the grip 53 can be reached without squatting down when the user performs the operation, which is beneficial to improving the use experience of the stroller.
In summary, through the above two embodiments, when the seat device 200 is switched in the direction, the push rod frame 102 of the stroller of the present invention is folded behind the bottom bracket 2, and does not interfere with the seat device 200 or interfere with the legs of the child sitting on the seat device 200, the seat device 200 can rotate around the rotation center line a extending in the up-down direction to be switched between the forward use state and the backward use state, the direction change operation of the child can be realized without getting off the stroller, and the operation steps are simple and convenient.
