Detailed Description

As shown in fig. 1 to 5, the present invention discloses a novel stroller convertible between an unfolded state and a folded state, the stroller comprises a handle 1, a first linkage 2, a second linkage 3, a front leg 4, a rear leg 5 and a third linkage 6, the upper sides of the first linkage 2 and the second linkage 3 are respectively pivoted to different positions of the handle 1 through a first pivot 21 and a second pivot 30, the lower sides of the first linkage 2 and the second linkage 3 are respectively pivoted to different positions of the front leg 4 through a third pivot 22 and a fourth pivot 41, so that the handle 1, the first linkage 2, the second linkage 3 and the front leg 4 form a four-bar structure, and the third pivot 22 is located above the fourth pivot 41 when the stroller is in the unfolded state; the rear leg 5 is pivoted with the second linkage member 3 through a fifth pivot shaft, and the fifth pivot shaft is positioned at the lower side of the second pivot shaft 30 and at the rear side of the fourth pivot shaft 41; the rear leg 5 is further pivoted to the third link 6 through a sixth pivot 52, the sixth pivot 52 is located on the upper side of the fifth pivot 51; the third link 6 is also pivotally connected to the lower side of the first link 2 and the front leg 4 via the third pivot 22, and the third pivot 22 is located behind the sixth pivot 52.

Preferably, the sixth pivot 52 is located at the front upper side of the fifth pivot 51.

When the infant stroller is folded, the handle 1 is rotationally moved backwards and downwards and is enabled to approach towards the rear feet 5, and due to the characteristic of the four-bar linkage structure, the upper sides of the second linkage part and the second linkage part 3 are also driven to rotate backwards and downwards to approach towards the rear feet 5; due to the seesaw principle, the front leg 4 is driven by the lower side of the second linkage 3 to move upwards and rotate, so that the rear side of the third linkage 6 and the lower side of the first linkage 2 are pushed to rotate upwards, the front side of the third linkage 6 is pulled by the upper side of the rear leg 5, and meanwhile, the upper side of the first linkage 2 rotates backwards and downwards and approaches to the rear leg 5, so that the rear side of the third linkage 6 and the upper side of the front leg 4 are pushed to rotate forwards at the same time, namely, the lower side of the first linkage 2, the upper side of the front leg 4 and the rear side of the third linkage 6 rotate forwards and upwards at the same time, so that the lower side of the front leg 4 rotates backwards and approaches to the rear leg 5 (as shown in fig. 3 and 4); that is, when the folding operation is required, as long as the handle 1 is rotated, other components of the infant stroller of the present invention will automatically and jointly move together, and the infant stroller is rotated, moved and folded until the components can not relatively rotate, and the infant stroller of the present invention is completely folded. Therefore, the folding operation of the infant stroller is simple and convenient. And when utility model infant's shallow is under fold condition, handlebar 1, first linkage 2, second linkage 3, preceding foot 4 are close to relatively, and back foot 5 diminishes with preceding foot 4 contained angle relatively again to it is whole less (as shown in fig. 5) to go out infant's shallow volume after folding.

In this embodiment, preferably, the second linkage member 3 includes a first section 31 and a second section 32 extending forward from a lower end of the first section 31, the rear leg 5 is pivotally connected to the first section 31 or the second section 32 through the fifth pivot 51, and a front side of the second section 32 is pivotally connected to the front leg 4 through the fourth pivot 41. Preferably, the lower side of the first section 31 or the second section 32 is pivotally connected to the rear foot 5. With such arrangement, when the infant stroller is folded, the front side of the second section 32 can rotate to the rear side of the rear leg 5 as soon as possible along with the rotation of the second linkage 3, so that the folding speed is faster, and after the infant stroller is folded, the front side of the second section 32 can rotate to a larger angle at the rear side of the rear leg 5, so that the relative included angle between the front leg 4 and the rear leg 5 is smaller, and the volume of the infant stroller after being folded is smaller.

In this embodiment, the third link 6 is pivoted together with the lower side of the first link 2 and the front leg 4 by the third pivot 22, so that the assembly is more convenient. In other embodiments, it may be provided that the third link 6 is connected to the first link 2 via a seventh pivot, which is located behind the sixth pivot 52 (not shown). And the seventh pivot may be located between the first pivot 21 and the third pivot 22, or may be located below the third pivot 22. With such an arrangement, in the folding process of the infant stroller, when the handle 1 is rotated backward and downward and is simultaneously moved toward the rear feet 5, the entire front feet 4 are driven by the lower side of the second linkage 3 to rotate upward along with the rotation of the handle 1, the upper side of the first linkage 2 and the upper side of the second linkage 3 backward and downward and are moved toward the rear feet 5, so that the lower side of the first linkage 2 is driven by the front feet 4 to rotate upward, and because the entire first linkage 2 is moved toward the rear feet 5, the rear side of the third linkage 6 is driven to rotate toward the rear feet 5, the upper side of the front feet 4 is pushed to rotate forward, and the lower side of the front feet 4 is rotated backward and is moved toward the rear feet 5. Until the components can no longer move rotationally relative to one another. Therefore, in the folding process of the infant stroller, all components can be naturally linked, so that the folding operation of the infant stroller is simple and convenient.

In another embodiment, the third link 6 may also be pivotally connected to the front leg 4 via a seventh pivot (not shown), and the seventh pivot is located behind the sixth pivot 52. And the seventh pivot may be located on the upper side of the third pivot 22, or may be located between the third pivot 22 and the fourth pivot 41. With such an arrangement, when the stroller is folded, the rider 1 is rotated and moved backward and downward and is moved closer to the rear leg 5, and as the front leg 4 is rotated upward by the lower side of the second link 3 and the first link 2 is moved toward the rear leg 5, the rear side of the third link 6 is rotated upward, so that the components of the stroller cannot be rotated relatively. Therefore, in the folding process of the infant stroller, all the components can be naturally linked, so that the folding operation of the infant stroller is simple and convenient.

Preferably, the infant stroller further comprises a seat (not shown), the third link 6 is configured as a seat support of the seat, i.e. the third link 6 itself is a part of the seat, and the lower back of the seat is pivotally connected to the seat support frame, i.e. to the third link 6; alternatively, the seat is connected to the third linkage 6. That is, when the infant stroller of the present invention is folded, the seat can be rotated and folded along with other components, so that the overall folding operation of the infant stroller of the present invention is more convenient.

The front lower part of the front foot 42 is provided with a front wheel 7, and the rear lower part of the rear foot 53 is provided with a rear wheel 8.

In the above description of the orientation, the front wheel 7 is located at the front, the rear wheel 9 is located at the rear, the rider 15 is located at the upper side, the front wheel 6 and the rear wheel 7 are located at the lower side, and the left and right side brackets 10 are located at the left and right sides. It will be appreciated that as the viewing angle changes, the relative orientation changes.

Although the embodiments of the present invention have been described in detail, the description is only a preferred embodiment of the present invention, and should not be considered as limiting the scope of the utility model, and all equivalent variations and modifications made within the scope of the present invention should be included in the scope of the present invention.
