Referring to the children's carriage shown in Figures 1-5, it includes a vehicle frame with an unfolded state and a folded state.

The vehicle frame includes side brackets 1 on both sides, and the side brackets 1 include a rear bracket assembly, a front bracket 2 that is rotatably connected to the rear bracket assembly through a first pivot 63, and is rotatably connected to the rear bracket assembly through a tenth pivot 61. The push rod 4. As shown in FIG. 1 , the rear bracket assembly includes a rear bracket 3 and a base 6 fixedly connected to the front end of the rear bracket 3 through a pin shaft 62 . The front end of the base 6 is rotatably connected to the rear end of the front bracket 2 through the first pivot 63 , and the rear end of the base 6 is rotatably connected to the front end of the hand push rod 4 through the tenth pivot 61 . The rear support 3 is provided with a sliding part 32 which can slide along the length direction of the rear support 3 and a locking structure 34 for locking the sliding part. Wherein, the front end of the front frame 2 is connected with a front wheel assembly 21 , and the rear end of the rear frame 3 is connected with a rear wheel assembly 31 . Specifically, the sliding member 32 may be a slider.

Between the rear brackets 3 on both sides is provided with a rear support frame 8 that can expand and contract along the left and right directions of the vehicle frame, and one end of the rear support frame 8 is rotatably connected to the slider; direction and front-to-back direction telescopic front support frame, one end of the front support frame is rotatably connected to the slider, and the other end of the front support frame is rotatably connected to the front support frame 2;

When the slider is in the unlocked state, it will drive one end of the front support frame and one end of the rear support frame 8 to slide down simultaneously, so that the rear supports 3 on both sides are moved closer to each other and then the front supports 2 on both sides are moved closer to each other, while the front supports 2 Close to each other with rear support 3.

The rear support frame 8 is a first cross brace group 8 , which includes a first link 81 and a second link 82 that intersect each other and are rotatably connected to each other by a second pivot 83 at the intersection. One end of the first connecting rod 81 and the second connecting rod 82 are rotatably connected to the upper ends of the rear brackets 3 on both sides through the third pivot 35 and the fourth pivot (not shown in the figure) respectively, the first connecting rod 81 and the other end of the second connecting rod 82 are rotatably connected to the sliders 32 on both sides through the fifth pivot (not shown in the figure) and the sixth pivot 811 respectively.

The front support frame is specifically a cross bracing structure, including at least two groups of second cross bracing groups 7 sequentially arranged along the front and rear directions of the vehicle frame, and each second cross bracing group 7 includes crossing each other and passing through the seventh pivot at the intersection. 76 The third connecting rod and the fourth connecting rod that are rotatably connected to each other. One end of the third connecting rod 72 of the second cross support group 7 on the leftmost side is rotatably connected to the slider 32 of the left rear bracket 3 and One end of the fourth connecting rod 71 is rotatably connected to the left front bracket 2; one end of the third connecting rod 73 of the second cross brace group 7 on the far right is rotatably connected to the right front bracket 2 One end of the upper and fourth connecting rod 74 is connected to the sliding part 32 of the right rear bracket 3 in a rotating manner. The third connecting rod 72 of the previous second cross bracing group 7 of the adjacent two groups of second cross bracing groups 7 is rotatably connected to the fourth connecting rod 74 of the rear second cross bracing group 7 through the eighth pivot 77 , the fourth connecting rod 71 of the previous second cross bracing group 7 of the second cross bracing group 7 of two adjacent groups and the third connecting rod 73 of the rear second cross bracing group 7 are rotatable through the ninth pivot 78 connect. And the second cross bracing groups 7 of two adjacent groups are suspended in the air at the connecting positions. In the present invention, the third connecting rods of the second cross brace group 7 of the same group are arranged above the fourth connecting rods, and all of them have a wave structure along the extending direction of the length.

As shown in the figure, the children's carriage of the present utility model is also connected with a support rod 5 between the hand push rod 4 and the slider 32, one end of which is rotatably connected with the hand push rod 4 through the eleventh pivot 41, and its other One end is rotatably connected to the slider 32 through the twelfth pivot 51 .

Through the above structure, when the slider 32 is unlocked, sliding the slider 32 along the rear bracket 3 will simultaneously drive the support rod 5, one end of the first link 81 and the second link 82, and the third link 73 and the fourth link. One end of the link 71 moves downward. The downward movement of the support rod 5 will cause the rear end of the hand push rod 4 to fold closer to the rear bracket 3, and the downward movement of one end of the first connecting rod 81 and the second connecting rod 82 will cause the two to rotate mutually and contract along the left and right directions to drive The rear brackets 3 on both sides move closer to each other, and the downward movement of one end of the third connecting rod 73 and the fourth connecting rod 71 will make the two connecting rods in the same second cross brace group 7 rotate mutually so as to drive the front bracket 2 and the rear bracket 3 along the The front and rear directions move closer to each other. The closeness of the rear brackets 3 on both sides will cause the second cross brace group 7 of the two adjacent groups to shrink in the left and right directions, and then drive the brackets 3 on both sides to fold in the left and right directions.

In order to realize the expansion and contraction of the cross brace structure along the left and right, front and rear directions, in the present utility model, one end of the third connecting rod 72 of the second leftmost cross brace group 7 is rotatably connected to the left side through the first L-shaped connector 721. On the slider 32 of the side rear bracket 3 and one end of the fourth link 71 is rotatably connected to the left front bracket 2 through the second L-shaped connector 711; One end of the three link 73 is rotatably connected to the front bracket 3 on the right side through the third L-shaped connector 731 and one end of the fourth connecting rod 74 is rotatably connected to the rear right side through the fourth L-shaped connector 741. on the slider 32 of the bracket 3. All the above-mentioned L-shaped connectors are provided with a first sub-pivot and a second sub-pivot whose axis lines are perpendicular to each other. Wherein the first sub-pivot is used for connecting the corresponding link and the connecting piece, and the second sub-pivot is used for connecting the connecting piece and the corresponding front bracket or sliding piece.

For the convenience of operation, a one-handed control mechanism (not shown in the figure) connected with the locking structure 34 is also provided on the frame of the children's vehicle of the present utility model, which is used to release the locking state between the locking structure 34 and the slider 32 . Specifically, the locking structure 34 is a locking pin arranged on the rear bracket, the rear bracket 3 is provided with a through hole 33, and the one-handed control mechanism is a link connected between the locking pins on both sides through the through hole 33. That is, the two ends of the linkage are inserted into the rear support 3 through the through holes 33 on both sides, and are connected with the corresponding locking pins. Other parts of the linkage are exposed on the rear bracket 3, which is convenient for users to operate by hand. Such as the link is a flexible rope. Through this structure, the user can realize the folding of the stroller with one hand.
