Detailed Description

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

The lower sides of the first connecting rod 2 and the second connecting rod 3 are pivoted at different front and rear positions of the rear foot 6. In this embodiment, the lower side of the first link 2 is pivotally connected to the rear leg 6 through a first pivot 21, the lower side of the second link 3 is pivotally connected to the rear leg 6 through a second pivot 31, and the first pivot 21 is located behind the second pivot 31.

In this embodiment, the rear side of the front foot 5 is pivotally connected to the second link 3 through a third pivot 51, preferably, the third pivot 51 is located on the upper side or/and the rear side of the second pivot 31.

In this embodiment, the front side of the third link 4 is pivoted to the front leg 5 by a fourth pivot 41, the fourth pivot 41 is located at the lower side or/and the front side of the third pivot 51, and preferably, the fourth pivot 41 is located at the lower side or/and the front side of the second pivot 31.

The rear side of the third connecting rod 4 and the lower side of the first connecting rod 2 can be pivoted with a rear foot 6 through the first pivot 21; or the rear side of the third connecting rod 4, the lower side of the first connecting rod 2 and the lower side of the second connecting rod 3 are respectively pivoted at different positions of the rear foot 6. In this embodiment, the rear side of the third link 4 is pivotally connected to the rear leg 6 by a fifth pivot 42, and the fifth pivot 42 is located at the rear side of the second pivot 31. Preferably, the fifth pivot 42 is located between the first pivot 21 and the second pivot 31, so that the third link 4 can be made less long, thereby not only saving material, but also making it easier and faster for the front end of the third link 4 to rotate backwards with the front foot 5 during folding of the frame. The rear side of the third connecting rod 4 can be pivoted to other suitable positions of the rear foot 6.

In this embodiment, the upper side of the first link 2 is pivotally connected to the rider 1 through a sixth pivot 22, the upper side of the second link 3 is pivotally connected to the rider 1 through a seventh pivot 32, and the seventh pivot 32 is located above the sixth pivot 32. So, the driver 1, the first connecting rod 2, the second connecting rod 3 and the rear foot 6 form a four-bar linkage structure together, and due to the characteristics of the four-bar linkage structure, when the frame is folded, the linkage of the driver 1, the first connecting rod 2, the second connecting rod 3 and the rear foot 6 is smooth, and after the frame is folded, the four parts are close to each other relatively, so that the volume of the folded frame is small.

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 2 and the second connecting rod 3 can be rotated backward and downward to be close to the rear leg 6, and in the process of the backward and downward rotation of the second connecting rod 3, the front leg 5 can be forced to move downward, and through the cooperation of the third connecting rod 4, the front side of the front leg 5 and the front side of the third connecting rod 4 can be rotated backward together to be close to the rear leg 6 (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 6 until 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 utility model discloses the perambulator still including connect in the front wheel 20 of lower part before frame 10, connect in the rear wheel 30 of lower part behind frame 10, in this embodiment, front wheel 20 connect in lower part before preceding forefoot 5, rear wheel 30 connect in lower part behind 6 rear foot.

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.
