Detailed Description

As shown in fig. 1, 2 and 3, the infant stroller of the present invention includes a frame 10 convertible between an unfolded state and a folded state, the frame 10 includes a handle 1, front legs 2, rear legs 3, a first connecting rod 4, a second connecting rod 5 and a third connecting rod 6, the upper side of the first connecting rod 4 is pivoted with the handle 1, and the lower side is pivoted with the rear legs 3, the upper side of the second connecting rod 5 is pivoted with the handle 1, and the lower side is pivoted with the rear legs 3, the upper side of the third connecting rod 6 is pivoted with the second connecting rod 5, and the lower side is pivoted with the front legs 2, the rear side of the front legs 2 is pivoted with the rear legs 3.

The lower side of the first link 4 is pivotally connected to the rear leg 3 through a first pivot 41, the lower side of the second link 5 is pivotally connected to the rear leg 3 through a second pivot 51, and the first pivot 41 is located behind the second pivot 51.

The upper side of the first link 4 is pivotally connected to the rider 1 through a third pivot 42, the upper side of the second link 5 is pivotally connected to the rider 1 through a fourth pivot 52, and the third pivot 42 is located below the fourth pivot 52. Thus, the rider 1, the first link 4, the second link 5 and the rear leg 3 form a four-bar linkage structure together, and due to the characteristics of the four-bar linkage structure, the linkage of the rider 1, the first link 4, the second link 5 and the rear leg 3 is smooth in the frame folding process, and the four parts are relatively close to each other after the frame is folded.

The rear side of the front foot 2 and the lower side of the first connecting rod 4 can be pivoted with the rear foot 3 through the first pivot 41; or the rear side of the front foot 2, the lower side of the first link 4 and the lower side of the second link 5 are respectively pivoted at different positions on the rear foot 3, the rear side of the front foot 2 is pivoted at the rear foot 3 through a fifth pivot 21, and the fifth pivot 21 is positioned at the rear side of the second pivot 51, so that the front foot 2 can be driven to rotate by the third link 6 more easily during the folding process of the frame. Preferably, the fifth pivot 21 is located between the first pivot 41 and the second pivot 51, so that the lower ends of the front leg and the rear leg do not have too large a drop height after folding, thereby reducing the overall height of the folded frame.

In this embodiment, the upper side of the third link 6 is pivotally connected to the second link 5 through a sixth pivot 61, the sixth pivot 61 is located on the upper side of the second pivot 51, and preferably, the sixth pivot 61 is located between the second pivot 51 and the fourth pivot 52.

The lower side of the third link 6 is pivotally connected to the front leg 2 via a seventh pivot 62, and the seventh pivot 62 is located at the front side of the first pivot 41 or the fifth pivot 21. That is, when the rear side of the front leg 2 is pivoted to the rear leg 3 together with the lower side of the first link 4 by the first pivot 41, the seventh pivot 62 is located at the front side of the first pivot 41, and when the rear side of the front leg 2 is pivoted to the rear leg 3 by the fifth pivot 21, the seventh pivot 62 is located at the front side of the fifth pivot 21.

Preferably, the third link 6 is bent and includes a first section 63 parallel to the second link 5 when the frame is in the unfolded state and a second section 64 extending downward from the lower end of the first section 63, the upper end of the first section 63 is pivotally connected to the second link 5, and the lower end of the second section 64 is pivotally connected to the front leg 2, so that when the frame is in the unfolded state, the first section 63 of the third link 6 is parallel to the second link 5, thereby making the frame structure more compact and integral and more beautiful.

The frame 10 adopts the above structure, so that in the folding process, as long as the rider 1 is rotated forward and the lower side of the rider 1 is moved backward and downward, the rear sides of the first connecting rod 4 and the second connecting rod 5 can be rotated backward and downward to be close to the rear leg 3, and in the process of the backward and downward rotation of the second connecting rod 5, the third connecting rod 6 is forced to move downward, so that the third connecting rod 6 pushes the front leg 2 downward, and the front leg 2 is rotated toward the rear leg 3 to be close (as shown in fig. 2). That is, during the folding process, as long as the rider 1 is rotated forward and the lower side of the rider 1 is moved backward and downward, the other components of the frame are linked to rotate together and move to be close to the rear leg 3 until all the components of the frame are relatively close to each other, and the frame 10 is completely folded (as shown in fig. 3). Therefore, all the components of the frame 10 can be smoothly linked in the folding process, so that the folding process does not need to take too much force, and the folded product has smaller volume and is convenient to store and carry.

The frame 10 further includes a front wheel 20 connected to a front lower portion of the front leg 2 and a rear wheel 20 connected to a rear lower portion of the rear leg 3.

In the above description of the orientation, the rider 1 is located at the top, the front wheels 20 and the rear wheels 30 are located at the bottom, the front wheels 20 are located at the front, and the rear wheels 30 are located at the rear.
