The above-mentioned foldable stroller frame is characterized in that a control mechanism is provided at the hinge joint between the armrest pole and the armrest rod, and the control mechanism includes a pushing wheel and a driving wheel, and an engaging gear is arranged between the pushing wheel and the driving wheel , the push wheel is pulled by the button arranged on the armrest rod through the pull wire, the armrest rod is hinged with the front and rear connectors, and the front and rear connectors are equipped with a drive wheel to pull and control the front rod and the front and rear connectors through the pull wire. The inserting block rotated between, and the groove corresponding to the inserting block is provided on the said front strut.

The foldable stroller frame above is characterized in that the armrest is provided with a sunshade bracket between the armrest rod and the armrest support rod. The sunshade bracket is a four-bar mechanism composed of a handrail rod, a scaffold lower rod, a scaffold front rod, and a scaffold upper tie rod sequentially hinged.

Compared with the prior art, the utility model has the following advantages:

The utility model adopts two sets of four-bar mechanisms and one set of five-bar mechanisms. When folding the baby carriage, it can be folded horizontally and vertically at the same time, so that the volume of the folded baby carriage is smaller in the horizontal and vertical directions, which is convenient for packaging, transportation and storage. In the open state, the space between the rear wheels of the stroller is wider than that of the front wheels, which increases the use space and stability.

【Detailed ways】

The foldable stroller frame includes a left support 100 and a right support 200 which are symmetrical to each other. Between the left support 100 and the right support 200 are connected inner pull struts 6 and inner pull struts which intersect each other and are hinged at the intersection. Strut two 7, described left support 100, right support 200 comprise vertical folding frame 2 respectively, and vertical folding frame 2 is connected with handrail bar 14, and described vertical folding frame 2 is formed by bottom frame The four-bar mechanism composed of the outer cross bar 8, the upper section of the rear support rod 10, the front and rear connectors 11, and the front support rod 12; Rod 8 and rear pole lower section 9 are sequentially hinged to form a four-bar mechanism; the armrest pole 13 is hinged between the armrest pole 14 and the front and rear connectors 11, and the left bracket 100 and the right bracket 200 are provided with Cross strut one 15 and cross strut two 16, the five-bar mechanism formed by sequentially hinged joints of the rear strut upper section 10, the front and rear connectors 11, the armrest strut 13, the cross strut one 15, and the cross strut two 16 .

Between the left bracket 100 and the right bracket 200 there are three sections of the first strut 17 , the middle strut 18 , and the second strut 19 hinged in sequence. The armrest pole 13 and the armrest bar 14 are hinged with a control mechanism 20, the control mechanism 20 includes a push wheel 21, a driving wheel 22, and an engaging gear 23 is arranged between the push wheel 21 and the driving wheel 22. The wheel 21 is pulled by the button 30 arranged on the armrest bar 14 through the pull wire. The armrest strut 13 is hinged with the front and rear connectors 11, and the front and rear connectors 11 are provided with a drive wheel 22 to pull and control the front strut 12 through the pull wire. The front support rod 12 is provided with a groove 41 corresponding to the insert block 40 that rotates between the front and rear connecting pieces 11 . The armrest is provided with a sunshade bracket 50 between the armrest bar 14 and the armrest pole 13 . The sunshade bracket 50 is a four-bar mechanism composed of the handrail rod 14, the lower support rod 51 of the scaffold, the front support rod 52 of the scaffold, and the upper tie rod 53 of the scaffold.

When folding, firstly lift the front pole 52 of the scaffolding, and then the whole sunshade bracket 50 can be folded up by using the four-bar mechanism, and the button 30 is pushed to drive the push wheel 21 to push the engagement gear 23 into the armrest pole 13 , the engagement gear 21 is disengaged from the engagement gear on the handrail rod 14, so that the handrail rod 14 can rotate relative to the handrail pole 13, and the handrail rod 14 drives the driving wheel 22 to rotate, and the driving wheel 22 is connected with the steel wire rope to drive the plug 40, inserting Block 40 is just extracted from slot 41, and front pole 12 just can be rotated relative to armrest pole, and the six-bar mechanism of horizontal folding frame 3 just can be folded, and armrest pole 13 is folded forward again, vertically The four-bar mechanism of the folding frame 2 is folded and the upper section 10 of the rear pole drives the lower section 9 of the rear pole to drive the four-bar mechanism of the folding bottom frame 1 to fold horizontally.
