The cross bars 13 of the two side push rod assemblies 1 are rotatably connected to each other, and in a more specific connection structure, one end of each cross bar 13 is rotatably connected to each other, and the other end of each cross bar 13 is fixedly connected to the upper end of the upper push rod 21 of the side push rod assembly 1.
The push rod assembly has an open state and a folded state, when the push rod assembly is in the open state, the two cross rods 13 are relatively unfolded, the upper push rod 11 and the lower push rod 12 are in relatively unfolded positions, and the locking device is in a locking state; when the push handle assembly transits from the open state to the folded state, the two cross bars 13 are relatively close to each other, specifically, the two cross bars 13 rotate and protrude out of a plane formed by the two upper push rods 11, and the upper push rods 11 and the lower push rods 12 in the two side push rod assemblies 1 are switched to the first relative positions, so that the locking device is in an unlocking state; when the push rod assembly is in the folded state, the two cross bars 13 are kept relatively close, and the upper push rod 11 and the lower push rod 12 are in a relatively folded position.
In a more preferred embodiment, the upper push rod 11 and the lower push rod 12 are connected in a relatively movable manner in addition to being relatively pivotable, in particular, the upper push rod 11 and the lower push rod 12 are relatively extended when the upper push rod 11 and the lower push rod 12 are in the relatively extended position and the first relative position, and the upper push rod 11 and the lower push rod 12 are relatively retracted when the upper push rod 11 and the lower push rod 12 are in the relatively retracted position. In a more specific connection structure, the lower portion of the upper push rod 11 is inserted therein from the upper end of the lower push rod 12 from top to bottom and movably.
The locking means described above are used to define the relative movement relationship between the upper push rod 11 and the lower push rod 12, namely: the relative movement relationship between the upper push rod 11 and the lower push rod 12 is defined when the locking device is in the locked state, and the upper push rod 11 and the lower push rod 12 can be relatively moved when the locking device is in the unlocked state. The above-mentioned relative folding position and the first relative position are switched by the relative movement of the upper push rod 11 and the lower push rod 12.
The present embodiment provides a specific structure of a locking device, which includes a locking hole 121 formed on a push rod 12, a locking tongue 14 slidably connected to an upper push rod 11 and detachably inserted into the locking hole 121, and an elastic member (not shown in the drawings) capable of inserting the locking tongue 14 into the locking hole 121, wherein the elastic member is preferably a compression spring, and the locking tongue 14 has a slope 141 capable of slidably contacting with an edge of the locking hole 121 to separate the locking tongue 14 from the locking hole 121. More specifically, the inclined surface 141 is parallel to the axis of relative pivoting between the upper push rod 11 and the lower push rod 12.
In a more preferred embodiment, when the push rod assembly is in the open position, the upper push rod 11 and the lower push rod 12 on the left side of the folding stroller are each inclined rearward and leftward from bottom to top, and the upper push rod 11 and the lower push rod 12 on the right side of the folding stroller are each inclined rearward and rightward from bottom to top. Compared with the folding state of the push rod assembly, the distance between the bottom ends of the lower push rods 12 at the left side and the right side is unchanged, and the upper push rods 11 at the left side and the right side are closer. Specifically, in the transition process of the push rod assembly from the open state to the folded state, the two cross bars 13 are relatively close to each other, so that the upper push rods 11 (and the lower push rods 12) on the left side and the right side are more close to each other. In this embodiment, when the push rod assembly is in the folded state, the lower push rods 12 on the left and right sides are parallel to each other, and the upper push rods 11 on the left and right sides are parallel to each other, so that the angle of the lower push rod 12 (and the upper push rod 11) is changed slightly in the left and right direction during the folding process of the push rod assembly. It should be noted that, when the bottom of the lower push rod 12 is rotationally connected with other components of the folding stroller, a certain gap is formed between the bottom of the lower push rod 12 and the components at the rotational connection position, and meanwhile, when the push rod assembly is in the open state, the inclination angles of the upper push rod 11 and the lower push rod 12 on the left and right sides in the left and right directions are smaller, so that when the upper push rod 11 and the lower push rod 12 on the left and right sides are rotationally driven by the two cross rods 13 to rotate and approach each other, the upper push rod 11 and the lower push rod 12 on the left and right sides can be mutually close to each other to be parallel under the condition that the distances between the bottoms of the left and right lower push rods 12 are unchanged.
Push rod assembly theory of operation:
When the push rod assembly is folded, the rotating connection part of the cross rods 13 on the left side and the right side is pushed forward, the rotating connection part moves forward, the two cross rods 13 relatively rotate to approach each other, the rotation between the two cross rods 13 drives the upper push rod 11 and the lower push rod 12 on the left side and the right side to approach each other to be parallel, meanwhile, the rotation between the two cross rods 13 drives the upper push rod 11 and the lower push rod 12 on the left side and the right side to pivot, the upper push rod 11 and the lower push rod 12 are switched from the relatively unfolding position to the first relative position, and in the process of relatively pivoting between the upper push rod 11 and the lower push rod 12, the inclined plane 141 of the lock tongue 14 is in sliding contact with the edge of the lock hole 121, so that the lock tongue 14 is pushed to move against the force of the elastic piece and withdraw from the lock hole 121, so that the locking device is unlocked, and after the locking device is unlocked, the upper push rod 11 and the lower push rod 12 can relatively move, at the moment, the lower push rod 11 (or the cross rod 13) is retracted into the lower push rod 12, so that the folding of the push rod assembly is completed.
The embodiment also provides a folding child stroller, which comprises a foldable and openable frame, wheels connected to the bottom of the frame, seat pockets arranged on the frame, and a frame locking device for locking the frame in an open state. The frame is provided with the push rod assembly.
