Detailed Description

First embodiment

As shown in fig. 1 to 5, the stroller frame 10 of the present invention is convertible between an unfolded state and a folded state, and includes a push handle 1, a first connecting member 2, a handle 3, a rear leg 4, a front leg 5, and a second connecting member 6;

the upper sides of the first connecting piece 2 and the handle 3 are respectively and rotatably connected with different positions of the push handle 1, the lower sides of the first connecting piece 2 and the handle 3 are respectively and rotatably connected with different positions of the rear foot 4, and the push handle 1, the first connecting piece 2, the handle 3 and the rear foot 4 form a four-connecting piece structure;

the rear side of the front foot 5 is rotationally connected with the front side of the rear foot 4;

the front side of the second connecting piece 6 is rotationally connected with the front foot 5, and the rear side is rotationally connected with the first connecting piece 2; when the upper side of the first connecting piece 2 rotates backwards and downwards, the first connecting piece 2 can drive the front foot 5 to rotate towards the rear foot 4 by pulling the second connecting piece 6.

Preferably, the rear side of the front foot 5 and the first connecting element 2 are respectively and rotatably connected with different positions of the rear foot 4. The rear side of the second connecting piece 6 and the rear foot 4 are respectively connected with different positions of the first connecting piece 2 in a rotating way. With such an arrangement, it can be ensured that the second connecting piece 6 and the front foot 5 can be driven to rotate when the upper side of the first connecting piece 2 rotates backwards and downwards.

The first connecting piece 2 is rotationally connected with the rear foot 4 around a first rotating shaft 41, the rider 3 is rotationally connected with the rear foot 4 around a second rotating shaft 42, and the rear side of the front foot 5 is rotationally connected with the rear foot 4 around a third rotating shaft 43.

When the stroller frame 10 is in the unfolded state, the third rotating shaft 43 is located at the front side of the first rotating shaft 41. Preferably, the third rotating shaft 43 is located at the front upper side of the first rotating shaft 41. The arrangement is such that when the front leg 5 is pulled by the second connecting member 6, the front leg rotates backward relative to the third rotating shaft 43, rather than upward.

The front side of the second connecting piece 6 is rotatably connected with the front foot 5 around a fourth rotating shaft 61, and when the stroller frame 10 is in the unfolded state, the fourth rotating shaft 61 is positioned in front of the third rotating shaft 43. Preferably, the fourth rotating shaft 61 is located at the front lower side of the third rotating shaft 43. That is, the front sides of the rear foot 4 and the second connecting piece 6 are respectively and rotatably connected with different positions of the front foot 5, and the joint of the second connecting piece 6 and the front foot 5 is positioned at the front lower side of the joint of the rear foot 4 and the front foot 5. With such an arrangement, the front foot 5 can be further ensured to rotate relatively backwards and closer to the rear foot 4 more smoothly and more quickly by taking the third rotating shaft 43 as a rotating shaft when being subjected to the pulling force of the second connecting piece 6.

Thus, the first rotating shaft 41, the third rotating shaft 43 and the fourth rotating shaft 61 are distributed in a triangular shape, and the third rotating shaft 43 is located above the connecting line where the first rotating shaft 41 and the fourth rotating shaft 61 are located.

The rear side of the second connecting piece 6 is rotatably connected with the first connecting piece 2 around a rotating shaft five 62, the upper side of the first connecting piece 2 is rotatably connected with the push handle 1 around a rotating shaft six 11, and in the embodiment, when the stroller frame 10 is in the unfolded state, the rotating shaft five 62 is positioned between the rotating shaft one 41 and the rotating shaft six 11.

When the stroller frame 10 is in the unfolded state, the second rotating shaft 42 is located at the rear side of the first rotating shaft 41, that is, the first rotating shaft 41 is located between the second rotating shaft 42 and the third rotating shaft 43. Preferably, the first rotating shaft 41 is located at the front upper side of the second rotating shaft 42. The upper side of the rider 3 is rotatably connected with the push handle 1 around a seventh rotating shaft 12, and the seventh rotating shaft 12 is positioned on the lower side of a sixth rotating shaft 11. Thus, the push handle 1, the first connecting piece 2, the handle 3 and the rear foot 4 form a four-connecting-piece structure.

Because the stroller framework 10 of the present invention adopts the above structure, when the stroller framework 10 is to be folded, only the lower side of the push handle 1 needs to be rotationally moved toward the rear leg 4 toward the rear lower side, and simultaneously the upper side of the push handle 1 is rotated forward, due to the characteristics of the four-link structure, the first link 2 and the handle 3 can be easily driven to rotationally move toward the rear lower side toward the rear leg 4, and the first link 2 can pull the second link 6 to also rotationally move toward the rear lower side when rotationally moving toward the rear lower side, so that the front leg 5 can be driven by the second link 6 to rotate toward the rear leg 4 (the front leg 5 rotates about the third rotating shaft 43 as the rotating shaft) (as shown in fig. 3); until the push handle 1, the driver 3, the first connecting piece 2, the second connecting piece 6 and the front foot 5 are all close to the rear foot 4, the framework is completely folded (as shown in figures 4 and 5). Therefore, when the framework is folded, only the lower side of the push handle 1 is required to rotate towards the direction of the rear foot 4 towards the rear lower side, and the upper side of the push handle 1 is required to rotate forwards at the same time, other components of the child stroller framework 10 can be linked and rotated very easily and smoothly to approach each other, so that the folding operation is very labor-saving, and the vehicle folding burden of parents holding a child can be reduced; moreover, because the stroller frame 10 is completely folded, the components of the stroller frame 10 are relatively close to each other, so that the overall size of the folded stroller frame is small, and the stroller frame is convenient to store and carry.

The front lower part of the front foot 5 is connected with a front wheel 20, the rear lower part of the rear foot 4 is connected with a rear wheel 30, and when the stroller framework 10 is folded, the front wheel 20 can rotate backwards along with the front foot 5.

Second embodiment

As shown in fig. 6 to 10, the present embodiment is different from the first embodiment in the connecting position of the second connecting member 6 ' and the first connecting member 2 ' and the arrangement of the first connecting member 2 ', and the other structures are the same.

In the present embodiment, the rotating shaft five 62 'is located between the front leg 5 and the rear leg 4, and preferably, the rotating shaft five 62' is located between the rotating shaft four 61 'and the rotating shaft one 41'.

In this embodiment, preferably, the first connecting member 2 'includes a first section 21' extending from bottom to top in an inclined manner and a second section 22 'extending from a lower end of the first section 21' to top, an upper side of the first section 21 'is rotatably connected to the handle bar 1 around the rotating shaft six 11, and a rear side of the second connecting member 6' is rotatably connected to a front side of the second section 22 'around the rotating shaft five 62'. Preferably, the positions of the first rotating shaft 41 ', the fifth rotating shaft 62 ' and the sixth rotating shaft 11 ' are distributed in a triangle. The rear leg 4 may be rotatably connected to the first section 21 'of the first connecting member 2', may be rotatably connected to the second section 22 'of the first connecting member 2', or may be rotatably connected to a connecting position of the first section 21 'and the second section 22', but the rear side of the second connecting member 6 'is not coaxially and rotatably connected to the first connecting member 2' and the rear leg 4. That is, the rear side of the second connecting member 6 ' is rotatably connected to the first connecting member 2 ', and the second connecting member 6 ' is configured such that the rear side thereof is not coaxially and rotatably connected to the first connecting member 2 ' and the rear leg 4, in the embodiment, the first rotating shaft 41 and the fifth rotating shaft 62 ' cannot be the same shaft.

The first section 21 'and the second section 22' may be integrally formed, or may be two components fixedly connected to each other.

Because the stroller frame 10 'of the present invention adopts the above-described structure, when the stroller frame 10' is to be folded, similarly, only the lower side of the push handle 1 is rotated and moved towards the direction of the rear foot 4 towards the rear lower side, and simultaneously the upper side of the push handle 1 is rotated forwards, due to the characteristics of the four-link structure, the first link 2 '(i.e. the upper side of the first vertical rod first section 21') and the rider 3 can be easily driven to rotate and move towards the rear foot 4 towards the rear lower part, while the lower front side of the first connecting member 2 '(i.e. the front side of the second section 22' of the first connecting member 2 ') pulls the rear side of the second connecting member 6' to rotate relatively upward and rearward, so that the front foot 5 can rotate towards the direction of the rear foot 4 under the driving of the front side of the second connecting piece 6' (the front foot 5 still uses the third rotating shaft 43 as the rotating shaft when rotating) (as shown in fig. 8); until the push handle 1, the driver 3, the first connecting piece 2 ', the second connecting piece 6' and the front foot 5 are close to the rear foot 4, the framework is completely folded (as shown in figures 9 and 10). Thus, when the stroller framework 10 'of the present embodiment is folded, only the lower side of the push handle 1 is required to rotate toward the rear lower side toward the rear leg 4, and the upper side of the push handle 1 is required to rotate forward, other components of the stroller framework 10' can be easily and smoothly linked to rotate to approach each other, so that the folding operation is labor-saving, and the folding burden of parents holding a child can be reduced; moreover, because the stroller frame 10' is completely folded, the components thereof are relatively close to each other, so that the overall volume of the folded stroller frame 10 is small, and the stroller frame is convenient to store and carry. And because the positions of the first rotating shaft 41 ', the fifth rotating shaft 62' and the sixth rotating shaft 11 'are distributed in a triangular manner, when the upper side of the first connecting piece 2' rotates backwards and downwards, the front lower side of the first connecting piece 2 'can drive the rear side of the second connecting piece 6' to move backwards by a larger distance, so that the front foot 5 can be pulled to rotate backwards by a larger angle, namely, the front foot 5 can be closer to the rear foot 4, and the size of the folded framework can be smaller.

The invention also discloses a stroller, which comprises the stroller framework 10, and the stroller framework 10 has the advantages, so that the stroller also has the advantages.

In the above description of the orientation, the front wheel 20 is located at the front, the rear wheel 30 is located at the rear, the push handle 1 is located at the upper position, and the front wheel 20 and the rear wheel 30 are located at the lower position.
