[0026] like Figure 1 , 2As shown in Figures 3 and 4, the support for a baby stroller frame of the present invention includes a front leg 1, a rear leg 2, a first connecting member 3, a second connecting member 4, a front wheel 5 connected to the front lower part of the front leg 1, and a rear wheel 6 connected to the rear lower part of the first connecting member 3; the rear leg 2 includes a first connecting portion 21 and a second connecting portion 22 pivoted to the lower side of the first connecting portion 21 at the front side, the first connecting member 3 includes a first connecting section 31 and a second connecting section 32 pivoted to the rear side of the first connecting section 31 at the upper side, and the rear wheel is connected to the rear lower part of the second connecting section 32; the first connecting section 31 is cross-arranged with the second connecting member 4, the rear side of the second connecting member 4 is pivoted to the rear leg 2, and the front side and the front side of the first connecting section 31 are both pivoted to the front leg; the first connecting portion 21 is cross-pivoted with the first connecting section 31, and the rear side of the second connecting portion 22 is pivoted to the second connecting section 32, so that the first connecting portion 21, the second connecting portion 22, the first connecting section 31, and the second connecting section 32 form a four-bar structure.

[0027] Preferably, the front side of the first connecting member 3 is pivotally connected to the upper side of the front leg 1 , that is, the front side of the first connecting section 31 is pivotally connected to the upper side of the front leg 1 .

[0028] Preferably, the rear side of the second connecting member 4 is pivotally connected to the upper side of the rear leg 2 .

[0029] As shown in 5 and 6, when the bracket is folded, the upper side of the rear leg 2 is rotated and moved relatively backward and downward, that is, the upper side of the first connecting part 21 is rotated and moved backward and downward, so that the lower side of the first connecting part 21 is rotated relatively forward, driving the second connecting part 22 to move forward, thereby pulling the second connecting section 32 of the second connecting member 3 to rotate forward, and the rear wheel 6 moves forward together; and when the upper side of the first connecting part 21 is rotated and moved backward, it pulls the front leg 1 to rotate and move backward through the second connecting member 4, and the front wheel 5 also moves backward; the front side of the first connecting part 31 of the first connecting member 3 is also driven to rotate forward and downward; until the front leg 11, the first connecting part 21 of the rear leg 22, the second connecting part 22, the first connecting section 31 of the first connecting member 3, the second connecting section 32, and the second connecting member 4 are rotated close to each other, and the frame is completely folded (as shown in FIG. Figure 7 , 8 As shown). Because the rear foot 2 includes a first connecting portion 21 and a second connecting portion 22 pivotally connected to each other, and the first connecting member 3 includes a first connecting segment 31 and a second connecting segment 32 pivotally connected to each other, it is equivalent to that the rear foot and the first connecting member are both configured as two-stage, and combined with the connection between the front foot and the second connecting member, the overall length and height of the folding bracket are greatly reduced, thereby reducing the overall volume of the bracket after folding.

[0030] The baby stroller frame of the present invention includes the above bracket, and also includes a rider 7 and a third connecting member 8. The lower side of the rider 7 is pivotally connected to the upper side of the first connecting portion 21, the rear side of the third connecting member 8 is pivotally connected to the rider 7, and the front side is pivotally connected to the first connecting section 31, so that the rider 7, the third connecting member 8, the first connecting portion 21, and the first connecting section 31 form a four-bar linkage.

[0031] In other embodiments, the lower side of the rider 7 may also be pivotally connected with the upper side of the first connecting part 21 and the rear side of the second connecting member 4. In this way, the rider 7, the third connecting member 8, the first connecting part 21, and the first connecting section 31 form a four-bar linkage, and the rider 7, the third connecting member 8, the front foot 1, and the second connecting member also form a four-bar linkage. The lower side of the rider 7 may also be pivotally connected with the rear side of the second connecting member 4.

[0032] The front side of the third connecting member 8 may also be connected to the upper side of the front foot 1 , or the front side of the third connecting member 8 , the upper side of the front foot 1 , and the front side of the first connecting section 31 are pivotally connected together.

[0033] When the baby carriage frame of the present invention is folded, the rider 7 is rotated forward and downward, and at the same time, the lower side of the rider 7 is rotated and moved backward and downward, and the rear side of the third connecting member 8 is driven to rotate downward and lean against the first connecting section 31 of the first connecting member 3; the rear side of the second connecting member 2 is also driven to rotate backward and downward, so that the lower side of the front leg 1 is pulled to rotate backward; and the upper side of the rear leg 2, that is, the upper side of the first connecting portion 21, is also driven to rotate relatively backward and downward, so that the second connecting portion 22 moves forward and drives the second connecting section 32 to move forward, until the front leg 11, the first connecting portion 21 of the rear leg 22, the second connecting portion 22, the first connecting section 31 of the first connecting member 3, the second connecting section 32, the second connecting member 4, the rider 7, and the third connecting member 8 are all rotated close to each other, and the frame is completely folded.

[0034] The baby stroller frame of the present invention further comprises a push handle bar 9, the lower side of which is pivotally connected to the upper side of the rider 7 or connected to the rider 7 so as to be relatively movable up and down. When the push handle bar 9 cannot rotate relative to the rider 7 or move relatively downward, the push handle bar 9 is equivalent to an upward extension of the rider 7, which is convenient for the caregiver to push the stroller frame without bending over; the push handle bar 9 is rotated to be close to the rider 7 or moved downward so that the upper side of the push handle bar 9 is roughly at the same height as the upper side of the rider 7, that is, the push handle bar 9 is also in a folded state, thereby preventing the push handle bar 7 from affecting the height of the entire stroller frame after folding and affecting the volume of the entire stroller frame after folding.

[0035] The baby stroller frame further comprises a transverse pivot rod 10 , to which the lower side of the rider 7 , the upper side of the rear foot 2 , and the rear side of the second connecting member 4 are all pivotally connected.

[0036] Preferably, the second connecting member 4 includes a rear connecting portion 41 extending forward and backward and a front connecting portion 42 extending outward and forward from the front end of the rear connecting portion 41, the rear side of the rear connecting portion 41 is pivotally connected to the pivot rod 10, and the front side of the front connecting portion 42 is pivotally connected to the front foot.

[0037] In this embodiment, the baby carriage frame includes left and right side brackets 100, each of the side brackets 100 includes the front leg 11, the rear leg 22, the first connecting member 3, the second connecting member 4, the rider 7, and the third connecting member 8. The lower side of the rider 7, the upper side of the rear leg 2, and the rear side of the second connecting member 4 of each side bracket 100 are pivotally connected through the pivot rod 10. Therefore, the pivot rod 10 can not only connect the rider 7, the rear leg 2, and the second connecting member 4, making the connection more convenient, but also make the frame more stable when it is in the unfolded state because the left and right side brackets 100 are connected.

[0038] The baby carriage frame further includes a connecting rod 43 connected to the front end of the rear connecting portion 41 of the second connecting member of the left and right side brackets 100 at the left and right ends respectively. Preferably, the rear connecting portion 41, the front connecting portion 42 and the connecting rod 43 of the two second connecting members are integrally formed.

[0039] In other embodiments, the second connecting rod 43 may also be made into other feasible shapes, that is, the specific shape is not limited as long as it can achieve the above-mentioned connection function.

[0040] The baby stroller frame also includes a front foot cross bar 11 whose left and right ends are respectively connected to the front feet of the left and right side brackets 100, and a second cross bar 12 whose left and right ends are respectively connected to the front side of the first connecting part of the first connecting member of the left and right side brackets 100. The front foot cross bar 11 and the second cross bar 12 can further ensure the stability of the frame in the unfolded state.

[0041] The baby carriage frame of the present invention can also be made into a tricycle style as required, that is, one front leg and two rear legs or one rear leg and two front legs, and other components can be arranged as required. For example, in the tricycle style of one rear leg and two front legs, the front side of the one front leg is pivotally connected to the middle part of the pivot rod.

[0042] The baby stroller frame further includes a backrest 13 , the lower side of which is pivotally connected to the pivot rod 10 .
