Specific embodiment
As shown in Figure 1, perambulator of the present invention include one can be converted between unfolded state and folded state vehicle frame 10, setting
In 10 front lower portion of vehicle frame front-wheel 20, be set to the rear-wheel 30 of 10 rear lower of vehicle frame, the vehicle frame 10 includes driver
1, first connecting rod 2, second connecting rod 3, third connecting rod 4, front foot 5, the rear foot 6, the first connecting rod 2 intersect with the third connecting rod 4
Formula pivot joint, and 2 upper end of the first connecting rod is articulated in the driver 1, lower end is articulated in front foot 5, the 3 upper end pivot of second connecting rod
It is connected to the driver 1, lower end is articulated in 4 upper end of third connecting rod, and 4 lower end of third connecting rod is articulated in the rear foot 6, after described
6 front end of foot and front foot 5 are pivotally connected, and the front-wheel 20 is connected to 5 front lower portion of front foot, and the rear-wheel 30 is connected to the rear foot 30
Rear lower.
Preferably, 2 upper end of first connecting rod is pivotally connected by one first pivot 21 with driver 1,3 upper end of second connecting rod
It is pivotally connected by one second pivot 31 with driver 1, and first pivot 21 is located at 31 downside of the second pivot.Thus the driver 1,
First connecting rod 2, second connecting rod 3 and third connecting rod 4 are formed as a four-bar linkage structure.
Preferably, 4 lower end of third connecting rod is pivotally connected by a third pivot 41 with the rear foot 6,6 front end of the rear foot passes through
One the 4th pivot 51 is pivotally connected with front foot 5, and the 4th pivot 51 is located at 41 front side of third pivot.
Preferably, 2 lower end of first connecting rod is pivotally connected by one the 5th pivot 52 with front foot 5, described 52,5th pivot
In 51 rear side of the 4th pivot.To which the first connecting rod 2, third connecting rod 4, front foot 5, the rear foot 6 are again formed as a double leval jib
Structure, in this way, the vehicle frame of perambulator of the present invention is formed as be pivotally connected up and down two four-bar linkage structures.
Vehicle frame 10 using the above structure, thus in folding process, as long as rotating the driver 1 forward and making institute simultaneously
It states 1 lower end of driver to move down, that is, second connecting rod 3 may make also to rotate toward the back lower place, also may make intersect and be pivotally connected first to connect
Bar 2 and 4 relative rotation of third connecting rod and the close rear foot 6, and the angle between first connecting rod 2 and third connecting rod 4 becomes smaller, and the
The rotation of one connecting rod 2 can also drive the front foot 5 with the 4th pivot 51 is rotary shaft and is rotated close to the rear foot 6 (as shown in Figure 2).
I other words in folding process, as long as rotating the driver 1 forward and 1 lower end of driver being made to move down simultaneously, vehicle frame
Other assemblies can be linked to be rotated and the close rear foot 6 together, until each component of vehicle frame is homogeneously to close to (as shown in Figure 3), vehicle
Frame 10 folds completely.In this way, each component of vehicle frame 10 link in folding process it is very smooth, and fold after the volume of timber it is smaller.
As shown in figure 4, the vehicle frame 10 includes left and right sides bracket 100, each side stand 100 includes the vehicle
Hand 1, first connecting rod 2, second connecting rod 3, third connecting rod 4, front foot 5, the rear foot 6.
In the present embodiment, the front-wheel 20 is disposed as two groups with rear-wheel 30, is connected to left and right sides bracket 10
5 front lower portion of front foot and 6 rear lower of the rear foot, and the not phase of the spacing between the spacing between two groups of front-wheels 20 and two groups of rear-wheels 30
Together, in this way, can avoid front foot 5 towards when the rotation of the rear foot 6, front-wheel 20 and rear-wheel 30 mutually hinder and form interference, thus in vehicle
After frame folds, two groups of front-wheels 20 can be between two groups of rear-wheels 30 or two groups of rear-wheels 30 are before described two groups
Between wheel 20, so that the front and rear width of folded perambulator is smaller, the volume of timber is smaller.In other embodiments, described two
Group front-wheel 20 between spacing and two groups of rear-wheels 30 between spacing can be set into it is identical, thus can avoid front foot 5 after
When foot 6 rotates to certain distance, front-wheel 20 contacts with each other with rear-wheel 30, thus front-wheel 20 and rear-wheel 30 can front and back be supported in together
On ground, the perambulator after conveniently folding is stood.
(not shown) in other embodiments, being also possible to vehicle frame 10 further includes a front foot connecting rod, and the front foot connecting rod
Left and right ends are connected to 5 lower end of left and right sides bracket front foot, and 20, the front-wheel are arranged one group, and one group of front-wheel
20 are connected among the front foot connecting rod；Or, vehicle frame 10 includes a rear foot connecting rod, and the left and right ends of the rear foot connecting rod connect respectively
Be connected to 6 lower end of the left and right sides bracket rear foot, the rear-wheel 30 are arranged one group, and one group of rear-wheel 30 be connected to it is described after
Among foot connecting rod, to form toy tricycle style.In another embodiment, two groups of front-wheels 20 can also be all connected to described
On front foot connecting rod, two groups of rear-wheels 30 can also be all connected on the rear foot connecting rod.
The specific connection type of the front-wheel 20, rear-wheel 30 and front foot 5, the rear foot 6 or front foot connecting rod, rear foot connecting rod can be to appoint
Feasible structure known in anticipating, and be not technical key point of the present invention, therefore, not repeat them here.
In the description of above-mentioned orientation, be where the driver 1 it is upper, under being where the front-wheel 20, rear-wheel 30, with described
Before being where front-wheel 20, after being where the rear-wheel 30, to be left and right where two side stand 100.
