9002 axial direction is parallel to each other.The axial direction of 61 shafts 6001 and the axial direction of shaft 1001 one by one are perpendicular.
As shown in Figure 1, have the stroller frame of the children trolley of the back rest 3 provided in the present invention in unfolded state,
First side back rest 31 is rigidly supported with the second side back rest 32 under the action of connecting rod rest component 33, back support bar on first
311 parts that are overlapped in the longitudinal direction with first time back support bar 312 are minimum, back support bar 321 and second time back support bar on second
322 parts that overlap in the longitudinal direction are minimum so that the total length longest of the first side back rest 31 and the second side back rest 32,
Being oriented for back support bar is arranged upward at this time, by providing back rest supports with children are combined into cover for seat etc..
When the stroller frame of children trolley is folded from unfolded state to folded state, as shown in fig. 6-7, children trolley
While front-rear direction and whole height direction volume-diminished, make the first side stand 11 to the second side under the action of link 4
Holder 12 is mutually drawn close, while the back rest of both sides is drawn close mutually, and backrest on first is driven under the action of connecting rod rest component 33
Bar 311 slides in opposition with first time back support bar 312 so that the part overlapped in the longitudinal direction becomes more；Back support bar 321 on second
It is slid in opposition with second time back support bar 322 so that the part overlapped in the longitudinal direction becomes more.When the stroller frame of children trolley
When positioned at folded state, as shown in Fig. 3 and Fig. 8, the intersection between upper back support bar 311,321 and lower back support bar 312,322
All reach most, part misaligned at this time is respectively on first on the lower part of back support bar 311 and second under back support bar 321
Portion, at this time the height of back rest 3 be not higher than the height of side stand 11,12 so that the whole height of back rest 3 becomes smaller, and drops significantly
The volume of short transverse of the stroller frame of low children trolley in folded state.
Embodiment two
In a kind of children trolley that an alternative embodiment of the invention provides, as illustrated in figures 4-5, the difference with embodiment one
It is：The structure of connecting rod rest component 33 in back rest 3 is different.
In the present embodiment, the more connecting rods that first connecting rod component 331 includes are respectively first connecting rod 3311 and third connecting rod
3312, the more connecting rods that second connecting rod component 332 includes are respectively second connecting rod 3321 and fourth link 3322, first connecting rod
3311, which rotate around 61 shafts 6001 with second connecting rod 3321, connect, one end of third connecting rod 3312 around six or two shafts 6002 with
One end of first connecting rod 3311 rotates connection, and one end of fourth link 3322 is around six or three shafts 6003 and second connecting rod 3321
One end rotates connection.
One end of first connecting rod 3311 rotates around 92 shafts 9002 with back support bar on second 321 and connect, third connecting rod
3312 other end and the first guiding mechanism 313 for being fixed in first time back support bar 312 are around 8001 company of rotating of Aug. 1st shaft
It connects；One end of fourth link 3322 and the second guiding mechanism 323 for being fixed in second time back support bar 322 are around 91 shafts 9001
Rotate connection, and the other end of second connecting rod 3321 rotates around eight or two shafts 8002 with back support bar on first 311 and connect.
It is similar with embodiment one, have the stroller frame of the children trolley of the back rest 3 provided in the present invention in expansion shape
When state, the first side back rest 31 is rigidly supported with the second side back rest 32 under the action of connecting rod rest component 33, is leaned on first
The part that back of the body bar 311 overlaps in the longitudinal direction with first time back support bar 312 is minimum, is leaned under back support bar 321 and second on second
The part that back of the body bar 322 overlaps in the longitudinal direction is minimum so that the total length of the first side back rest 31 and the second side back rest 32
Longest, at this time being oriented for back support bar be arranged upward, by providing back rest supports with children are combined into cover for seat etc..
When the stroller frame of children trolley is folded from unfolded state to folded state, as shown in fig. 6-7, children trolley
While front-rear direction and whole height direction volume-diminished, make the first side stand 11 to the second side under the action of link 4
Holder 12 is mutually drawn close, while the back rest of both sides is drawn close mutually, and backrest on first is driven under the action of connecting rod rest component 33
Bar 311 slides in opposition with first time back support bar 312 so that the part overlapped in the longitudinal direction becomes more；Back support bar 321 on second
It is slid in opposition with second time back support bar 322 so that the part overlapped in the longitudinal direction becomes more.When the stroller frame of children trolley
When positioned at folded state, as shown in figs. 5 and 8, the intersection between upper back support bar 311,321 and lower back support bar 312,322
All reach most, the height of back rest 3 is not higher than the height of side stand 11,12 at this time so that the whole height of back rest 3 becomes
It is small, greatly reduce the stroller frame of children trolley the short transverse of folded state volume.With one difference of embodiment
Be, in the present embodiment misaligned part be respectively on first on the top of back support bar 311 and second back support bar 321 it is upper
Portion.
Further, the foregoing is merely presently preferred embodiments of the present invention, is not intended to limit the invention, all in the present invention
Spirit and principle within, any modification, equivalent replacement, improvement and so on, should be included in protection scope of the present invention it
It is interior.
