It is enough fixed；
The both ends of seat 83 are rotatably connected with seatpost 5 by third engaging lug a3 respectively.
Shown in Fig. 3, seatpost 5, which moves downward, drives the first end rotation of the first swing rod 6 to move downward simultaneously downwards
Holder is drawn close, and the second end of the first swing rod 6 is moved upwards and drawn close to lower bracket, and the easy end of the second swing rod 7 is by moving upwards
And then front support rod 22 is driven to move right and drawn close to lower bracket, to make each component of vehicle frame draw close folding, side direction is finally rolled over
Overlapping state is as shown in Figure 4 and Figure 5, and fore-stock and handle 4 are located at lower bracket both sides at this time, and upper bracket is located at lower bracket and pushes away
Between bar.
Handle 4, upper rack posts 33 are namely driven by seatpost 5, the second swing rod 7 are driven by the first swing rod 6, then pass through the
Two swing rods 7 drive front support rod 22, to which folding process be rapidly completed.
It should be noted that：With the third engaging lug a3 in seatpost 5 be rotatably connected ground seat 83 both belonged to lateral frame 8 or
Baby's function of seating is provided simultaneously
In an embodiment of the present embodiment：
Return Fig. 2, seatpost 5 includes the flat segments 51 being connected smoothly and descending branch 52, the first end of handle 4 and upper
The middle part of strut 33 is rotatably connected with flat segments 51, and descending branch 52 is rotatably connected with the first swing rod 6；
First swing rod 6 includes that can turn with descending branch 52 ascent stage 61 being connected smoothly and bending section 62, ascent stage 61
Dynamic connection, bending section 62 are rotatably connected with the second swing rod 7.
Flat segments 51 can support seat 83, descending branch 52 that can coordinate with the ascent stage 61, to realize that children trolley is unfolded
When support handle 4 and upper rack posts 33, while seatpost 5 drives the close folding of front support rod 22.Bending section 62 has for realizing centre
Connection between the front support rod 22 and lower fulcrum bar 32 of angle drives.
With continued reference to Fig. 2, in an embodiment of the present embodiment：
Handle 4 includes upper push-rod 41 and lower push-rod 42, and upper push-rod 41 and lower push-rod 42 are rotatably connected, and upper push-rod 41 can
It is fixed relative to lower push-rod 42.
When expansion, the axial line of upper push-rod 41 and lower push-rod 42 overlaps, and when folding, is rotated in upper push-rod 41 and lower push-rod 42
Junction folds, and can further reduce the gap after the folding between upper push-rod 41 and lower bracket, to further increase folding
Folded effect and efficiency.
Preferably, frame locking mechanism is set between upper push-rod 41 and lower push-rod 42, can be locked when side vehicle frame is unfolded
Side stand 1, frame locking mechanism are controlled by the locking switch on handlebar stem 10, and frame locking mechanism and locking switch pass through drawing
Rope connection, after the locking switch on operation handlebar hand lever 10 opens locking, locking mechanism unlock.After frame locking mechanism unlock,
Such as Fig. 3, upper push-rod 41, lower push-rod 42, upper rack posts 33 and seatpost 5 form four-bar mechanism；Upper rack posts 33, seatpost 5, middle strut
31, lower fulcrum bar 32 and the first swing rod 6 form four-bar mechanism.
As shown in Fig. 2, in an embodiment of the present embodiment：
Children trolley further includes two handlebar stems 10；
Two handlebar stems 10 are respectively arranged at the upside of the second end of handle 4 and along perpendicular to two 4 place planes of handle
Direction setting.
In pushing children trolley and realizing folding process, handlebar stem 10 can be held and operated, it is simple and fast.
In an embodiment of the present embodiment：
As shown in Fig. 2, lateral frame 8 further includes the horizontal push rod 84 for connecting two handles 4；
The second end of handle 4 is provided with the 4th engaging lug a4, the both ends of horizontal push rod 84 respectively by the 4th engaging lug a4 with
Handle 4 connects.
It is moved to shown in Fig. 6, by the 4th engaging lug a4, two push rods can be made to draw close folding to middle part, such as Fig. 7 and figure
Shown in 8, to reduce the spacing between two side stands 1, the overall volume of the children trolley after folding further is reduced.
In an embodiment of the present embodiment：
As shown in Fig. 2, before lateral frame 8 further includes preceding cross support arm 81 between being located at two side stands 1 and is symmetrically disposed on
Two first engaging lug a1 at 81 both ends of cross support arm, two the first engaging lug a1 are between two side stands 1, the first engaging lug
The L-shaped structures of a1；
Each first engaging lug a1 is fixedly connected with front support rod 22, the other end and the preceding cross support arm of each first engaging lug a1
81 one end is rotatably connected and can fix.
As shown in Figure 9 and Figure 10, front support rod 22 and push rod are located at the both sides of lower fulcrum bar 32, and upper rack posts 33 are located at lower branch
Between bar 32 and push rod.Inwardly push both sides front support rod 22, two front support rods 22 can drive two the first engaging lug a1 to
Middle part is drawn close, and two the first engaging lug a1 rotate and draw close the cross support arm 81 before resisting to centre.Before further collapsing
Strut 22 reduces the overall volume of children trolley.
In an embodiment of the present embodiment：
As shown in Fig. 2, after lateral frame 8 further includes rear cross support arm 82 between being located at two side stands 1 and is symmetrically disposed on
Two second engaging lug a2 at 82 both ends of cross support arm, two the second engaging lug a2 are between two side stands 1, the second engaging lug
The L-shaped structures of a2；
Each second engaging lug a2 is fixedly connected with lower fulcrum bar 32, the other end and the rear cross support arm of each second engaging lug a2
82 one end is rotatably connected and can fix.
As shown in Figure 9 and Figure 10, after two side stands 1 are collapsed and folded, as shown in fig. 6, inwardly pushing the lower branch of both sides
Bar 32, two lower fulcrum bars 32 drive two the second engaging lug a2 to rotate and draw close during mutually drawing close, until second
Engaging lug a2 is resisted until rear cross support arm 82 can not be rotated further, and further reduces the spacing between two lower fulcrum bars 32, into
One step reduces overall volume.
In an embodiment of the present embodiment：
As shown in Fig. 2, preceding cross support arm 81 is provided with the first elongate slots 811, two the first engaging lug a1 along its length
It is rotationally connected with the both ends of the first elongate slots 811 respectively and embedded first elongate slots 811 can be rotated；
As shown in Fig. 2, rear cross support arm 82 is provided with the second elongate slots 821, two the second engaging lug a2 along its length
It is rotationally connected with the both ends of the second elongate slots 821 respectively and embedded second elongate slots 821 can be rotated.
As shown in figure 9, during two the first engaging lug a1 draw close folding to middle part, two the first engaging lug a1 can
It is caught in the first elongate slots 811, increase the first engaging lug a1 draws close rotational angle, further reduces two the first engaging lug a1
Between spacing, to further reduce the spacing between two front support rods 22.
Similarly, by the second engaging lug a2 collapse fold after be caught in the second elongate slots 821, also for can be further
The diminution even spacing between the first engaging lug a1, that is, further reduce the spacing between two lower fulcrum bars 32.With into
