Specific embodiment
As shown in Figure 1, 2, 3, the utility model children trolley includes having collapse state and the vehicle frame of unfolded state 100,
The vehicle frame 100 include driver 1, first connecting rod 2, second connecting rod 3, third connecting rod 4, fourth link 5, the 5th connecting rod 6, front foot 7,
The rear foot 8；2 upper end of first connecting rod is articulated in driver by the first pivot 11, and 3 rear end of second connecting rod passes through the second pivot
12 are articulated in driver 1, and the first pivot 11 is located at 12 upside of the second pivot；The third connecting rod 4 and 2 staggered form pivot of first connecting rod
It connects, and 4 upper end of third connecting rod is articulated in second connecting rod 3, lower end is articulated in front foot 7 or/and the rear foot 8；5 front end of fourth link
It is articulated in 2 lower end of first connecting rod, rear end is articulated in the rear foot 8；5th connecting rod, 6 front end is articulated in front foot 7, and rear end is articulated in
Double leval jib 5；7 rear side of the front foot be pivotally connected on front side of the rear foot 8.
When folding children trolley of the present invention, simultaneously driver 1 is rotated toward the mobile driver 1 in the back lower place and forward, from
And drive first connecting rod 2,3 rear end of second connecting rod toward back lower place moving in rotation；When 2 rear end of first connecting rod is rotated toward the back lower place,
Its front end is relatively toward front upper place moving in rotation, so that 5 front end of fourth link be pulled to rotate toward top is mobile, the rear foot 8 connects the 4th
The drive of bar 5 rotates forward close to front foot 7, and 6 upper end of the 5th connecting rod is also pulled and past top moving in rotation by fourth link 5；
And first connecting rod 2,3 rear end of second connecting rod toward the back lower place moving in rotation during, the third connecting rod 4 is also connected by second
Bar 3 pulls and rotates (as shown in Figure 2) toward the back lower place, i.e. the 100 smooth linkage of each component of vehicle frame, until front foot 7, the rear foot 8, driver
1, the mutual rotary folding of first connecting rod 2 is close, and second connecting rod 3 is substantially relatively parallel with first connecting rod 2, third connecting rod 4 also with
Second connecting rod 3 is substantially parallel, i.e., second connecting rod 3, third connecting rod 4 are generally under same linear state, fourth link the 5, the 5th
Connecting rod 6 is also at the folding collapse state (as shown in Figure 3) rotated close to front foot 7, the rear foot 8, so that the vehicle frame 100 after folding is whole
Body volume of timber very little.
4 lower end of third connecting rod is articulated in front foot 7 or/and the rear foot 8, i other words, before 4 lower end of third connecting rod can be articulated in
Foot 7 can also be articulated in the rear foot 8 or 4 lower end of third connecting rod and is pivotally connected with front foot 7, the rear foot 8 by same pivot.In the present embodiment
In, preferably, 4 lower end of the third connecting rod is articulated in 8 upside of the rear foot, so that more convenient third connecting rod 4 rotates backward, Er Qiexuan
It can more tend to be parallel to the rear foot 8 after turning, also can more tend to second connecting rod 3 in same linear state, so that vehicle frame
100 to fold the rear volume of timber smaller.
In the present embodiment, 4 upper end of third connecting rod is pivotally connected by third pivot 41 and second connecting rod 3, the third
Pivot 41 is located at 12 front side of the second pivot.
7 rear end of front foot is pivotally connected by the 4th pivot 71 with 8 front end of the rear foot, and 5 rear end of fourth link passes through the 5th
Pivot 81 and the rear foot 8 are pivotally connected, and the 5th pivot 81 is located at 71 downside of the 4th pivot.So set, when to fold, the 4th
Under the pulling of connecting rod 5, front foot 7 and the rear foot 8 can be as close to, and fourth link 5 can also have sufficiently large revolution space,
Can the state parallel with the rear foot 8 as past as possible it is close so that vehicle frame 100 after folding it is whole more tend to it is flat, i.e., so that
It is smaller that vehicle frame 100 folds the rear volume of timber.
5th connecting rod, 6 front end is articulated in front foot 7 by the 6th pivot 51, and the 6th pivot 51 also is located at the 4th pivot
71 downside of axis.So set, may make during folding, the 5th connecting rod 6 also has enough revolution spaces, so as to more rotate
Close to front foot 7, but also the close of front foot 7 and the rear foot 8 is not interfered, so that 100 volume of timber of vehicle frame after folding is smaller.
Preferably, when the vehicle frame 100 is in unfolded state, before 2 lower end of first connecting rod is located at front foot 7 in parallel
Work as first connecting rod to not only make 100 structure of vehicle frame more compact on the whole, and when under 100 unfolded state of vehicle frame in side
When 2 stress press down, front foot 7 can provide support force, so that vehicle frame 100 is more stable.The vehicle frame 100 further includes a connection piece 9,
3 lower end of second connecting rod is articulated in 9 upper end of connector, and 5 front end of fourth link is articulated in 9 lower end of connector (knot
Close Fig. 2, shown in 5), pass through the setting of connector 9 to realize that 2 lower end of first connecting rod is located at the purpose of 7 front side of front foot in parallel.
In the present embodiment, preferably, in the case where vehicle frame 100 is in unfolded state, the front foot 7 and the upper end of the rear foot 8 are whole
The bodily form becomes the arc of opening down.So set, not only make the more compact beauty of entire 100 shape of vehicle frame, it is even more important
It is that when vehicle frame 100 folds, front foot 7 can draw closer together with part of the rear foot 8 in addition to upper end, thus after being further reduced and folding
The volume of timber.
Under the children trolley further includes the front-wheel 200 for being set to 100 front lower portion of vehicle frame, is set to after vehicle frame 100
The rear-wheel 300 in portion.
As shown in FIG. 4,5,6, 7, the vehicle frame 100 includes left and right sides bracket 10 and the transverse direction for connecting two side stands 10
Connecting rod, each side stand include the driver 1, first connecting rod 2, second connecting rod 3, third connecting rod 4, fourth link 5,
Five connecting rods 6, front foot 7, the rear foot 8.
The transverse link includes back link 101 or/and the left and right that left and right ends are separately connected the left and right sides bracket rear foot 8
Both ends are separately connected the front rod 102 of left and right sides bracket front foot 7.
In the present embodiment, 102 left and right ends of front rod are connected to the lower end of left and right sides bracket front foot 7,
There are two the settings of front-wheel 200, is respectively arranged at 102 left and right sides of front rod, and there are two the settings of rear-wheel 300,
It is respectively arranged at the downside of the left and right sides bracket rear foot 8.In other embodiments, a front-wheel 200, a front-wheel can be only set
200 are connected to 102 middle part of front rod；It can also be not provided with front rod 102, two front wheels 200 are respectively arranged at left and right sides bracket
10 front foot, 7 downside.In another embodiment, the setting of two front wheels 200 plus a rear-wheel 300, i.e. back link 101 or so can also be taken
Both ends are connected to the lower end of the left and right sides 10 rear foot 8 of bracket, after which is connected in the middle part of two connecting rods.
In the description of above-mentioned orientation, before being where the front-wheel 200, after being where the rear-wheel 300, with the vehicle
Be where hand 1 it is upper, under being where the front and rear wheel 200,300.
