Detailed Description

The technical solution of the present invention will be further explained with reference to the accompanying drawings and specific embodiments.

Referring to fig. 1 to 3, a stroller includes a stroller frame having an unfolded state and a folded state, a front wheel assembly 6, a rear wheel assembly 7, and a locking mechanism for locking the stroller frame in the unfolded state. The cart frame is provided with side supports which are respectively arranged at the left side and the right side, and each side support comprises a front support 1, a rear support 2, a push rod support 3 and a connecting frame 4. A support frame 5 is arranged between the side supports at the two sides. Wherein:

the front bracket 1 comprises a front support rod 11 which is obliquely and upwards extended from front to back in an unfolded state, a front wheel assembly 6 is arranged at the bottom of the front support rod 11, and pedals 9 are further arranged between the lower parts of two groups of front support rods 11 which are respectively arranged at the left side and the right side.

The rear bracket 2 includes a rear lower bracket including a rear lower support rod 22 extending obliquely upward from rear to front in the unfolded state, and a rear upper support rod 21 slidably connected to the rear lower support rod 22, where a lower portion of the rear upper support rod 21 is relatively slidably inserted into a rod cavity of the rear lower support rod 22 in a length direction of the rear lower support rod 22, and the rear upper support rod 21 and the rear lower support rod 22 are relatively slidably extended and contracted in the length direction to extend or contract the rear bracket 2. The rear wheel assembly 7 is provided at the bottom of the rear lower support rod 22. The opposite sides of the two groups of rear lower support rods 22 are respectively provided with a sliding groove 23 extending along the length direction.

Push rod frame 3 includes at least a lower push rod frame including a lower push rod 31 extending obliquely upward from the front to the rear in the unfolded state, and an upper push rod frame including an upper push rod 32 extending obliquely upward from the front to the rear in the unfolded state, and push rod locking joint 33 for rotatably coupling and relatively locking lower push rod 31 and upper push rod 32. The lower portion of the lower push rod 31 is rotatably connected to the upper portion of the front support bar 11 through a fourth axis d, and the lower push rod 31 is rotatably connected to the upper portion of the rear upper support bar 21 through a fifth axis e. When the stroller frame is in the unfolded state, the rotational connection position of the lower push rod 31 and the front support rod 11 is located below the connection position of the lower push rod 31 and the rear upper support rod 21, that is, the axial lead of the fourth axis d is located below the axial lead of the fifth axis e in the length direction of the lower push rod 31.

The link 4 includes a connecting rod 41, the connecting rod 41 extends in the front-rear direction in the unfolded state, the front portion of the connecting rod 41 is relatively rotatably connected to the upper portion of the front link 11, and the upper portion of the front link 11, the lower portion of the lower push link 31, and the front portion of the connecting rod 41 are together rotatably connected about a fourth axis d. The rear portion of the connecting rod 41 is rotatably connected to the upper portion of the rear lower support rod 22 by a third shaft c.

In this embodiment, the support frame 5 is a seat frame, the support frame 5 extends in the front-rear direction in the unfolded state, and the support frame 5 includes two sets of side bars 51 symmetrically arranged in the left-right direction and extending in the front-rear direction, and two sets of cross bars 52 respectively arranged at the front-rear end portions of the two sets of side bars 51 and extending in the left-right direction. On each of the left and right sides of the stroller frame, the front portions of the side bars 51 are rotatably connected to the upper portion of the front stay 11 by the first shaft a. The rotary joint of the side rod 51 and the front rod 11 is located below the rotary joint of the lower push rod 31 and the front rod 11, i.e. the axis of the first shaft a is located below the axis of the fourth shaft d. The rear part of the side lever 51 is connected with the lower part of the rear upper support rod 21 in a relatively rotating manner, and here, specifically, the rear part of the side lever 51 and the rear upper support rod 21 are connected together in a rotating manner by a second shaft b, and the second shaft b is slidably inserted in the sliding groove 23. The junction of the rear part of the side lever 51 and the rear upper support lever 21 is located below the junction of the connecting lever 41 and the rear lower support lever 22, i.e. the second axis b is always located below the third axis c in the direction of the length extension of the rear bracket 2.

When the stroller frame is in the unfolded state, as shown in fig. 1 and 2, on each of the left and right sides of the stroller frame, the front support rod 11 extends obliquely upward from front to back along the length direction, the lower support rod 31 and the upper support rod 32 of the push rod frame 3 are oppositely unfolded and extend along the same length direction as the front support rod 11, the rear support frame 2 extends obliquely upward from back to front, the connecting rod 41 extends along the front-rear direction, the support frame 5 extends along the front-rear direction, and the stroller frame is compact in structure and has good bearing stability in the unfolded state.

When the stroller frame is converted from the unfolded state to the folded state, as shown in fig. 4 to 7, the push rod frame 3 is driven to rotate backward so as to be folded toward the rear side of the rear frame 2. The rear upper support rod 21 slides downwards to contract relative to the rear lower support rod 22, so that the length of the rear support 2 is gradually shortened, the front support 1, the rear support 2 and the push rod frame 3 are gradually folded along the front-rear direction, and the connecting frame 4 and the support frame 5 are gradually folded between the front support 1 and the rear support 2 along with corresponding rotation. And finally, driving the upper push rod frame and the lower push rod frame to be relatively overturned and folded, and completing the folding of the frame of the stroller.

In the folded stroller frame, as shown in fig. 8 and 9, the rear upper support 21 and the rear lower support 22 slide relative to each other to shorten the length of the rear frame 2, and the rotational joint of the lower push rod 31 and the front support 11 is shifted to be above the joint of the lower push rod 31 and the rear upper support 21 as the push rod frame 3 is turned over relative to the front frame 1, that is, the axis of the fourth shaft d is shifted to be above the axis of the fifth shaft e. The folded stroller frame is flat and has an overall height substantially equal to the height of the front frame 1 plus the front wheel assembly 6, and the height dimension is greatly reduced.

In some other embodiments, when the stroller frame is converted from the unfolded state to the folded state, the push rod frame 3 may be folded first, that is, the upper push rod 32 is folded relative to the lower push rod 31, and then the lower push rod 31 is driven to rotate backwards to be folded relative to the rear bracket 2. The rear upper strut 21 slidingly enters the rod cavity of the rear lower strut 22. The connecting rod 41 is relatively rotatably folded toward the front support rod 11, and the support frame 5 is relatively rotatably folded between the front support rod 11 and the rear support frame 2.

In some other embodiments, the upper push rod 32 is connected to the lower push rod 31 in a relatively sliding manner, and when the stroller frame is converted from the unfolded state to the folded state, the upper push rod 32 slides obliquely downward along the length direction of the lower push rod 31, so that the length of the push rod frame 3 is shortened.

The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose of the embodiments is to enable people skilled in the art to understand the contents of the present invention and to implement the present invention, which cannot limit the protection scope of the present invention. All equivalent changes and modifications made according to the spirit of the present invention should be covered by the protection scope of the present invention.
