To further decrease the volume after vehicle returns the vehicle to the garage and knock off, the front of bracket 1 is equipped with lower protruding block 12, and horizontal strut 3 is set to down
The lower end of convex block 12.
For the transverse strength for reinforcing vehicle frame, back stay 8 is L-shaped, is hinged with cross bar between the middle part of two back stays 8
81, the rear end of connecting rod 9 is articulated with the side of cross bar 81.
For make front support rod 6 and back stay 8 can synchronous folding mechanism, the lower end of front support rod 6 and the lower end of back stay 8 are articulated with jointly
The rear portion of bracket 1.
To save material, rotating block 5 is in convex, and the lower part of rotating block 5 is equipped with and escapes material mouth 51, the upper end of rotating block 5
It is hinged with the lower end of push rod 4, the lower end of rotating block 5 and the middle part of horizontal strut 3 are hinged, the middle part of rotating block 5 and connecting rod 9
Front end be hinged.
For the storage ability for enhancing perambulator, soft cloth part 100 is removably connected between two lower protruding blocks 12 and rear foot lever 2
For placing article.
The middle part of front support rod 6 and the middle part of push rod 4 are hinged, and the upper end of front support rod 6 and/or back stay 8 removably connects
It is connected to the sleeping basket 10 that can be rotated to it, so perambulator of the invention can individually or simultaneously carry one or two baby, therefore
Bearing capacity of the invention is very strong, simultaneously because sleeping basket 10 can be rotated relative to front support rod 6 and/or back stay 8, (sleeping basket 10 passes through
The detachable rotation seat of the prior art and be removably joined together with front support rod 6 and/or back stay 8), so that baby
It sitting and lying or can lie down on perambulator to different angle.
Present invention expansion is in use, as shown in Figure 1 or 2, (the first locking fills under the locking effect of the first locking device
It is set at the articulated position between handle stem 7 and push rod 4, and the first locking device uses the locking structure of the prior art, because
Details are not described herein for this its specific structure), handle stem 7 and push rod 4 lock and in line, and in the locking of the second locking device
(the second locking device is located at the articulated position between 5 upper end of 4 lower end of push rod and rotating block, and the second locking device under effect
Using the locking mechanism of the prior art comprising set on push rod 4 lower end and can its opposite elastic telescopic closing piece, set on closing piece
Have strip, correspondingly, the upper end of rotating block 5 is equipped with the card hole being caught in for strip to be locked), push rod 4 and rotating block 5 are locked
Calmly and in line, it is formed between push rod 4, front support rod 6, bracket 1 (together with horizontal strut 3) and rotating block 5 at this time stable
Delta link mechanism, so that can not be opposite between push rod 4, front support rod 6, bracket 1, horizontal strut 3 and rotating block 5
Rotation, under rotating block 5 and the lock state of front support rod 5, connecting rod 9 and back stay 8 also keep lock state, and pull rod 22 will at this time
Foot lever 22 struts afterwards, and frame for baby cart is under the stable use state being fully deployed at this time, at this time then can be as needed by one
A or two sleeping baskets 10 are individually or simultaneously installed on front support rod 6 and/or back stay 8, but also can according to need sleeping basket
10 turn to position as shown in Figure 6 to 8 (attention is not limited only to Fig. 6 to position shown in Fig. 8), to keep it individually or same
When carry one or two baby, and be also possible that baby sitting and lying or can lie down on perambulator to different angle.Work as needs
When folding bicycle frame, first has to remove the sleeping basket 10 being mounted on front support rod 6 or back stay 8, then press the unlock on handle stem 7
Device (is not shown in the figure, and the structure of tripper is consistent with tripper in the prior art, details are not described herein),
So that the first tripper unlocks and makes handle stem 7 that can rotate folding relative to push rod 4, link in the unlock of the first tripper
Under effect, the second tripper synchronizing unlocking, pushing handle stem 7 forward at this time makes it rotate folding of falling forward relative to push rod 4
While push rod 4 lower end drive rotating block 5 to the upper front of bracket 1 rotate, at this time the lower end of push rod 4 with respect to bracket 1 upwards
Front rotation, and the upper end of push rod 4 is then drawn close to bracket 1, while also opposite bracket 1 leans on front support rod 6 under the drive of push rod 4
Hold together, rotating block 5 relative to bracket 1 upwards front rotation while pull connecting rod 9 travel forward, connecting rod 9 travel forward drive after prop up
Bar 8 is rotated forward and is drawn close to bracket 1, while foot lever 2 rotates forward relative to bracket 1 after driving pull rod 22 to travel forward and pull
And opposite bracket 1 draws close folding, vehicle folding process is as shown in Figure 3 or Figure 4, is finally folded into state as shown in Figure 5.
