Detailed Description

As shown in fig. 1 to 6, the infant stroller of the present invention includes a frame 100 convertible between a folded state and an unfolded state, the frame 100 includes a handle 1, a first connecting member 2, a second connecting member 3, a third connecting member 4, a front leg 5 and a rear leg 6, the rear end of the first connecting member 2 is pivoted to the handle 1, the front end is pivoted to the second connecting member 3, the upper end of the third connecting member 4 is pivoted to the front side of the second connecting member 3, the lower end is pivoted to the front leg 5, the second connecting member 3 is further pivoted to the rear leg 6, and the lower side of the handle 1, the rear side of the front leg 5 and the rear leg 6 are pivoted to each other.

In the present embodiment, the lower side of the rider 1, the rear side of the front leg 5 and the rear leg 6 are pivotally connected to each other in such a manner that the rear side of the front leg 5 and the rear leg 6 are pivotally connected to different positions of the rider 1. Specifically speaking, the lower end of the rider 1 is pivoted with the rear end of the front foot 5, an extension rod 11 extends outwards from the lower side of the rider 1, and one end, far away from the rider, of the extension rod 11 is pivoted with the rear foot 6, so that the rear side of the front foot 5 and the rear foot 6 are respectively pivoted at different positions of the rider 1. In other embodiments, the extension rod 11 may not be provided, and the rear side of the front leg 5 and the rear leg 6 are directly pivoted with the rider 1.

In other embodiments, the lower side of the rider 1 and the rear side of the front leg 5 may be respectively pivoted to different positions of the rear leg 6; or, the lower side of the rider 1 and the rear leg 6 are respectively pivoted to different positions of the front leg 5; or, the lower side of the rider 1, the rear side of the front foot 5 and the rear foot 6 are pivoted together through a pivot.

The front end of the first connecting piece 2 is pivotally connected with the second connecting piece 3 through a first pivot 21, the second connecting piece 3 is pivotally connected with the rear leg 6 through a second pivot 31, the first pivot 21 is located at the front side of the second pivot 31, the upper end of the third connecting piece 4 is pivotally connected with the second connecting piece 3 through a third pivot 41, and the third pivot 41 is also located at the front side of the second pivot 31.

When the baby stroller of the utility model is folded, the handle 1 is rotated backwards and downwards, the rear ends of the first connecting pieces 2 are driven to rotate backwards and downwards together, so that the front end of the first connecting member 2 pulls the second connecting member 3, and thus forces the front side of the second connecting member 3 to rotate forward and downward around the second pivot 31, this rotational movement of the second link 3, in turn, forces the third link 4 to move downwardly, thereby driving the front foot 5 to move rotationally rearwardly, and when the rider 1 rotates downwardly rearwardly, the lower end of the front leg moves upwards relatively to provide certain assistance for the backward rotation movement of the front leg (as shown in fig. 3 and 4), until the rider 1, the first connecting piece 2, the second connecting piece 3, the third connecting piece 4, the front leg 5 and the rear leg 6 rotate relatively to approach each other, and the frame 100 is folded (as shown in fig. 5 and 6). That is, in the folding process of the frame, as long as the rider 1 is rotated backward and downward, other components of the frame 100 are linked to relatively rotate together, so that the components of the frame 100 are linked smoothly; and because all components of the frame rotate close to each other, the volume of the folded frame is small.

In this embodiment, it is preferable that the first pivot 21 is located between the second pivot 31 and the third pivot 41, so that the first connecting element 2 and the third connecting element 4 can both provide supporting force to the second connecting element 3 when the frame is in the unfolded state, and during the folding process of the frame, the pulling force applied to the second connecting element 3 by the first connecting element 2 is greater, and the pushing force applied to the front foot 5 by the third connecting element 4 is greater, so that the front foot 5 can rotate and move to the folded position more smoothly. In other embodiments, the upper end of the third connecting element 4 may also be pivotally connected to the front end of the first connecting element 2 through the first pivot 21 and the second connecting element 3, that is, the first pivot 21 and the third pivot 41 are a single pivot, or the third pivot 41 is located between the first pivot 21 and the second pivot 31.

The lower end of the third connecting element 4 is pivotally connected to the front leg 5 via a fourth pivot 42, the rear side of the front leg 5 is pivotally connected to the rider 1 and/or the rear leg 6 via a fifth pivot (not shown), and the fourth pivot 42 is located at the front side of the fifth pivot. With the arrangement, the third connecting part 4 can provide more stable supporting force for the second connecting part 3 through the support of the front foot 5, and when the frame 100 is folded, the second connecting part 4 can easily push the front foot 5 to rotate backwards by taking the fifth pivot as a rotating shaft through the third connecting part 4 to be close to the rear foot 6, so that the related components can be linked more smoothly in the folding process.

In this embodiment, the frame 100 further includes a push handle rod 7 and a fourth connecting member 8, the lower end of the push handle rod 7 is pivotally connected to the upper end of the handlebar 1 through a sixth pivot 71, the upper end of the fourth connecting member 8 is pivotally connected to the push handle rod 7 through a seventh pivot 81, and the sixth pivot 71 is located above the seventh pivot 81; the lower end of the fourth connecting element 8 and the rear leg 6 are pivotally connected to a first pivot point 61, the rider 1 and/or the front leg 5 and the rear leg 6 are pivotally connected to a second pivot point 62, and the first pivot point 61 is located above the second pivot point 61.

When folding frame 100, the forward rotation pushes away handle bar 7 and makes to push away the whole below of handle bar 7 and move backward simultaneously to fourth connecting piece 8 is driven the below of backward towards back foot 6 swivelling movement, and handlebar hand 1 is also driven the below of backward rotation, when handlebar hand 1 is rotatory down backward, can be through the linkage swivelling movement of first connecting piece 2, second connecting piece 3, third connecting piece 4 and drive preceding foot 5 and rotate backward and be close to back foot 6 promptly, until the frame is folding completely. So, in folding process, each subassembly of frame still links smoothly just, and because push handle pole 7 and fourth connecting piece 8 are also folded together thereupon in addition, after the frame is folding, push handle pole 7 and fourth connecting piece 8 also all rotate and are close to back foot 6 to do not increase the whole height after the frame is folded, so the volume of timber after folding to the frame is little influenced.

The arrangement of the push handle bar 7 and the fourth connecting piece has the advantages that the integral height of the handle 1 and the push handle bar 7 is higher in the unfolded state of the frame 100, so that the push of parents is facilitated; when the frame 100 is folded, the whole frame 100 can be folded by operating the push handle rod 7, so that the convenience of folding operation is not influenced, and the linkage smoothness of each component of the frame in the folding process is not influenced.

In the present embodiment, since the lower side of the handlebar 1 is also pivoted to the rear leg, the handlebar 7, the handlebar 1, the rear leg 6 and the fourth link 8 are configured as a four-link structure.

In this embodiment, the second pivot 31 is located between the first pivot point 61 and the second pivot point 62. Preferably, the lower end of the fourth connecting member 8 is pivotally connected to the front end of the rear leg 6.
