Problems solved by technology

[0002] The horizontally foldable stroller in the prior art includes a frame body and wheels arranged under the frame body, the frame body includes side brackets on both sides, and the side brackets include rear wheels Bracket, a push handle rotatably connected to the upper end of the rear wheel bracket, a back bar arranged on the frame body, a rear cross brace is arranged between the two side brackets, and the The rear cross brace is crossed by two rods and rotatably connected by the rotating shaft at the intersection. The two upper ends of the cross brace are respectively connected to the upper angle connectors on the side brackets on both sides in rotation. The two lower ends of the cross brace are respectively rotatably connected to the lower angle connectors on the side brackets on both sides, and the two upper angle connectors are respectively connected to the corresponding side push The two lower angled connectors are connected in rotation with the rear wheel brackets on the corresponding sides respectively, and the backrest bar is supported by the rear cross brace. In order to facilitate the horizontal folding The stroller is folded close together, and the rotation connection shafts of the two rods of the rear cross brace are almost located in the middle of the two rods, that is, the position of the rotation shaft is relatively high relative to the frame body, so when When the rear cross support supports the rear part of the backrest bar, the backrest bar is always tilted, and the backrest bar can only be adjusted to a half-lying position at the lowest, and the backrest bar cannot be adjusted to a substantially flat position

Abstract

The pram capable of being folded transversely includes frame and wheels, and the frame includes two side frames comprising back wheel rack, push handle connected to the upper part of the back wheel rack and back rod; and back cross strut between two side frames comprising the crossed first assembly and second assembly. The first assembly has the first upper link rod and the first lower link rod, the second assembly has the second upper link rod and the second lower link rod, the first upper link rod and the second upper link rod are connected pivotally, the second lower link rod and the second upper link rod are connected pivotally with limiting rod in between, and the first lower link rod and the first upper link rod are connected pivotally with limiting rod in between. The back cross strut makes the back rod regulated horizontally without affecting the folding of the whole pram.

Description

technical field [0001] The invention relates to a transversely foldable stroller, in particular to a rear cross brace arranged on the transversely foldable stroller.
