Embodiment
As shown in Figure 1, a kind of foldable baby stroller vehicle frame, includes two side stands and connects the connecting rod of two side stands
71st, 72,73,74, it is rotation connection between connecting rod two end and side stand, in the deployed state, to avoid side stand automatic turning,
At least two groups of rotation axis axis between connecting rod and side stand is in Different Plane, in the present embodiment, the axis of four groups of rotation axis
Line is in Different Plane, ensures the stability of vehicle frame.As shown in Figure 6 and Figure 7, after the completion of side stand folds, two side stands can
Inwardly 90 ° of upset, and in the same same plane parallel with connecting rod, that is to say, that at this time, the rotation of connecting rod and side stand
Axis axis is in same plane.
As shown in Fig. 2, side stand includes pulling handle rod 1, the first foot lever 3, the second foot lever 2, bottom bar 4, lower beam 5 and upper boom 6, push away
Barre 1, the first foot lever 3, bottom bar 4, the second foot lever 2 are rotatablely connected successively forms the first quadric chain, pulling handle rod 1, crus secunda
Bar 2, lower beam 5, upper boom 6 are rotatablely connected successively forms the second quadric chain, and two quadric chains are set for linkage, when wherein one
During the locking of a quadric chain, another quadric chain is similarly lock-out state, from achieving the purpose that stable vehicle frame.
As depicted in figs. 1 and 2, pulling handle rod 1 is made of the push-down handle bar 11 and upper pulling handle rod 12 being rotatablely connected, push-down handle bar
11 and upper pulling handle rod 12 length it is of substantially equal, in addition, both are not on same straight line, being so designed that helps to reduce vehicle frame
Width after folding.11 bottom of push-down handle bar is equipped with segmental arc 13, and segmental arc 13 is bent downwardly, and main purpose is to allow the first foot lever
3 is lower, avoids producing interference to the children of seating.13 end of segmental arc is rotatablely connected with the first foot lever 3, recess and in middle part
Two foot levers 2 are rotatablely connected, and two rotation axis 32,22 are in same vertical straight line, can further reduce segmental arc 13 and first
The interference effect of foot lever 3.
It is rotatablely connected as shown in Fig. 2, the first foot lever 3 and the second foot lever 2 are all top ends with pulling handle rod 1, bottom bar 4 is arranged on
Between first foot lever 3 and the second foot lever 2, upper boom 6 and lower beam 5 are between the second foot lever 2 and pulling handle rod 1, without prejudice to folding
On the premise of use, the length of bottom bar 4, upper boom 6 and lower beam 5 is the smaller the better.In order to ensure the flatness folded, the first foot lever
3rd, the second foot lever 2 and push-down handle bar 11 are in same plane, and bottom bar 4 and lower beam 5 are in the inner side of the plane, can thus allow
Close, diminution volume when first foot lever, the second foot lever and push-down handle bar fold as far as possible.Certainly preferably upper boom 6 is not also in this
In plane.
As shown in Figure 1, being also equipped with seat post 8 on side stand, seat post one end is rotatablely connected with upper boom 6, on pulling handle rod 1
It is additionally provided with the sliding sleeve 81 being slidably matched with seat post.The top of pulling handle rod 1 is equipped with handle 14, the place of 14 vertical pusher of handle 1
Plane, its length are substantially equal to the thickness after vehicle frame folding.
The bottom of first foot lever 3 is provided with the first wheel 31, the bottom of the second foot lever 2 is provided with the second wheel 21, wheel
Can be Double-wheel structure, can also single-wheel structure, the present embodiment is Double-wheel structure, and the first wheel 31 is universal wheel, fold when,
180 ° can be rotated due to free gravity.
As shown in Figure 1,71 both ends of connecting rod connect two pulling handle rods 1,72 both ends of connecting rod connect two second foot levers 72,73 liang of connecting rod
Two first foot levers 71 of end connection, 74 both ends of connecting rod connect two lower beams 5, to obtain suitable rotational angle, pulling handle rod 1, crus secunda
Bar 72, the first foot lever 71, be equipped with connection convex block on lower beam 5.
Fig. 3-7 is the utility model trolley vehicle frame folding process demonstration graph, as shown in Figures 3 and 4, during folding, will first be pushed away
For barre 1 around cradle head doubling, the top of upper pulling handle rod 12 reaches the bottom of push-down handle bar 11；Then pulling handle rod 1, handle are pushed
Bar 1 is rotated around rotation axis 22, close to the second foot lever 2, while the rotation axis between upper boom 6 and lower beam 5 is displaced outwardly.
As shown in figure 5, pulling handle rod 1 drives rotation axis 32 to be moved to upper left side, make the first foot lever 3 close to the second foot lever 2,
Close to while, under the effect of gravity, 180 degree is freely rotated due to the first wheel 31 vacantly.
The second foot lever 2 as shown in fig. 6,1 and first foot lever 3 of pulling handle rod reclines completely, the second foot lever 2 are stuck in the first wheel
Take turns in gap, the first wheel 31 and the second wheel 21 are in same plane, and two side stands, which fold, to be completed.
As shown in fig. 7, two side stands after folding inwardly are turned over and turn 90 degrees, it is arranged side by side, two vehicle frames appropriate due to designing
Between do not have gap substantially, two side stands are in approximately the same plane, the parallel all connecting rods of the plane.
By folding three times, the utility model children trolley reduces vehicle frame length, the ruler in three directions of width and thickness
It is very little, its volume is greatly reduced, it is easy to carry.
