Detailed ways

As shown in FIGS. 1 , 2 , 3 and 4 , the bracket for a baby carriage frame of the present invention includes a front foot 1 , a rear foot 2 , a first connecting piece 3 , a second connecting piece 4 , a front foot connected to the front lower part of the front foot 1 , a front foot The wheel 5 , the rear wheel 6 connected to the lower rear part of the first connecting piece 3 ; the rear foot 2 includes a first connecting part 21 and a second connecting part 22 pivotally connected to the lower side of the first connecting part 21 at the front side , the first connecting piece 3 includes a first connecting section 31 and a second connecting section 32 pivotally connected to the rear side of the first connecting section 31 on the upper side, and the rear wheel is connected to the second connecting section 32 The lower part of the rear; the first connecting section 31 and the second connecting piece 4 are arranged crosswise, the rear side of the second connecting piece 4 is pivotally connected to the rear foot 2, and the front side and the front side of the first connecting section 31 are both pivoted connected to the front foot; the first connecting portion 21 is pivotally connected to the first connecting section 31, and the rear side of the second connecting portion 22 is pivotally connected to the second connecting section 32, so that the first connecting portion 21, the second connecting portion The two connecting parts 22 , the first connecting section 31 and the second connecting section 32 form a four-link structure.

Preferably, the front side of the first connecting member 3 is pivotally connected to the upper side of the front foot 1 , that is, the front side of the first connecting segment 31 is pivotally connected to the upper side of the front foot 1 .

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

As shown in 5 and 6, when the bracket is folded, the upper side of the rear leg 2 is rotated and moved backward and downward, that is, the upper side of the first connecting portion 21 is rotated and moved backward and downward, so that the lower side of the first connecting portion 21 is rotated and moved. The relative forward rotation drives the second connecting portion 22 to move forward, thereby pulling the second connecting segment 32 of the second connecting member 3 to rotate forward, and the rear wheel 6 moves forward together with it; and the upper side of the first connecting portion 21 When it rotates and moves backward, the front foot 1 is pulled by the second connecting piece 4 to rotate and move backward, and the front wheel 5 also moves backward; the front side of the first connecting part 31 of the first connecting piece 3 is also driven to the Rotate front and bottom; until the front foot 11, the first connecting part 21, the second connecting part 22 of the rear foot 22, the first connecting section 31, the second connecting section 32, and the second connecting piece 4 of the first connecting piece 3 rotate close to , the frame is fully folded (as shown in Figures 7 and 8). Because the rear leg 2 includes the first connecting portion 21 and the second connecting portion 22 that are pivotally connected to each other, the first connecting member 3 includes the first connecting portion 31 and the second connecting portion 32 that are pivotally connected to each other, which is equivalent to the rear foot and the second connecting portion 32. A connector is set in two sections, and combined with the connection between the front foot and the second connector, the overall length and height of the folded bracket are greatly reduced, thereby reducing the overall volume of the folded bracket.

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

In other embodiments, the lower side of the driver 7 may also be pivotally connected with the upper side of the first connecting portion 21 and the rear side of the second connecting member 4, so that the driver 7 and the third connecting member 8 , The first connecting portion 21 and the first connecting section 31 are formed as a four-bar linkage mechanism, and the rider 7 , the third connecting member 8 , the front foot 1 and the second connecting member are also formed as a four-bar linkage mechanism. The lower side of the rider 7 can also be pivotally connected to the rear side of the second connecting member 4 .

The front side of the third connecting member 8 can also be connected with 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.

When the baby carriage frame of the present invention is folded, the rider 7 is rotated forward and downward, while 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 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 foot 1 is pulled and rotated backward; and the upper side of the rear foot 2, that is, the upper side of the first connecting portion 21 is also driven. Relatively backward and downward, the second connecting portion 22 moves forward and drives the second connecting segment 32 to move forward until the first connecting portion 21 , the second connecting portion 22 and the first connecting piece of the front foot 11 and the rear foot 22 The first connecting section 31 , the second connecting section 32 , the second connecting piece 4 , the rider 7 , and the third connecting piece 8 of 3 are all rotated and approached, and the frame is completely folded.

The baby carriage frame of the present invention further includes a push handle bar 9, the lower side of the push handle bar 9 is pivotally connected to the upper side of the rider 7 or connected to the rider 7 in a relatively up and down movement. When the push handle bar 9 cannot rotate or move downward relative to the rider 7, the push handle bar 9 is equivalent to the upward extension of the rider 7, which is convenient for the caregiver to push the frame without bending over; rotating the push handle bar 9. Move closer to the rider 7 or move the handlebar 9 downward so that the upper side of the handlebar 9 is approximately at the same height as the upper side of the rider 7, even if the handlebar 9 is also in a folded state, so as to avoid the pusher bar 7 Affects the height of the entire frame after folding and affects the volume of the entire frame after folding.

The baby carriage frame further includes a transverse pivot rod 10 , and 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 to the pivot rod 10 .
