With the relative telescopic along the longitudinal direction of rear bar 12.
Upper strut component 8 includes intersecting and in two upper struts 81 that infall phase pivot connects, two upper struts
81 updip extensions from front to back respectively, every upper strut 81 are realized as follows with the side stand of both sides 10 and are connected：On
The front of strut 81 is rotationally connected to the lower part of side front rod 2 or the lower part of hound 4, and rear portion of strut 81 turns on this
It is connected to dynamicly on the rear portion of other side seat bar 61.In the present embodiment, the front of upper strut 81 passes through 82 pivot of preceding connecting shaft
Be connected with front connector 83, the front connector 83 by the 5th axis 105 of aforementioned first axle 101/ with front rod 2 and hound 4
Phase pivot connects, and the axial line of preceding connecting shaft 82 is arranged mutual vertically with the axial line of first axle 101；The rear portion of upper strut 81
The rear portion of present bar 61 is rotationally connected by rear connectors 84, which is present on bar 61 after sliding sleeve 62
Side.
It includes the front wheels set on 11 bottom front of front bar that wheel assembly, which has be divided into the left and right sides two groups, every group of wheel assembly,
Part 20 and wheel assembly 30 set on 12 bottom rear portion of rear bar.When stroller frame is in unfolded state, referring to attached Fig. 1 to Fig. 4 institute
Show, the side stand 10 of both sides respectively self-deploys, and bottom bracing bar assembly 7 is unfolded with upper strut component 8 and is supported in left-right direction respectively
Between the side stand 10 of both sides, two groups of front components 20 are supported in ground jointly with wheel assembly 30.On each side side stand 10, bottom
Triangle stable support structure between bar 1, front rod 2 and rear pole 3 so that vehicle frame has good in the deployed state
Rigidity.
When needing to fold up stroller frame, after unlocking push rod locking piece 53, driven according to the directions A in such as Fig. 3
Upper push-rod 52 is set to overturn folding with respect to lower push-rod 51, until upper push-rod 52 overturns the rear side for collapsing to lower push-rod 51, such as Fig. 5 institutes
Show, at this point, locking joint 9 is unlocked；Continue according to the directions B in such as Fig. 5 to overturn 5 entirety of push rod forward, this makes each side side
It is relatively rotated between 10 midsole lever 1 of holder, front rod 2, rear pole 3, hound 4, seat bar assembly 6 and push rod 5 and gradually along upper
Lower direction is collapsed, and the opposite front bar 11 of the rear bar 12 in bottom bar 1 is gradually along the directions C forward slip so that 30 direction of wheel assembly
Approach front component 20 moves forward, as shown in Figure 6, Figure 7.At the same time, divide between strut 81 between two bottom supporting rods 71, on two
It does not relatively rotate and gradually gradually collapses in left-right direction, be further driven between each rod piece in each side stand 100 vertically
It gradually collapses in direction.Finally, stroller frame folds state as shown in Figure 8, Figure 9, in bottom bar 1 front bar 11 with rear bar 12 along front and back
Shorten to sliding, front rod 2, rear pole 3, hound 4, seat bar 61 and push rod 5 are close along the vertical direction to be collapsed, and bottom supporting rod group
Part 7 collapses so that two side stands 10 transversely collapse in left-right direction with upper strut component 8, and stroller frame is by front component 20
It is supported in ground jointly with wheel assembly 30.The size of vehicle frame in all directions after folding, which has, significantly to be reduced, each bar
Part arrangement is compact, and very smooth structure is presented, and convenient for storage and transports.
When needing the stroller frame being unfolded in use, only need to pull up upper push-rod 52, to make its with respect to lower push-rod 51
Overturning open after, and by lower push-rod 51 drive front rod 2 top and rear pole 3 top uplink after, each side side stand 10
In each rod piece just relative motion and gradually opened along the longitudinal direction with upper and lower directions, two bottom supporting rods 71 of bottom bracing bar assembly 7 it
Between, upper strut component 8 two on relatively rotate and be gradually opened in left-right direction respectively between strut 81 so that stroller frame edge
Left and right directions is gradually spread out.Until after stroller frame is fully deployed, locks and respectively locked at joint 9 and push rod locking piece 53, pushed away
Vehicle carriage is steadily locked under unfolded state.
To sum up, Bi-directional foldable stroller of the invention, vehicle frame folding principle is simple and reliable, and cart can be realized front and back, left
Right, upper and lower directions folding and expansion, it is easy to carry, it is easy to operate, it is highly practical.
The above embodiments merely illustrate the technical concept and features of the present invention, and its object is to allow person skilled in the art
Scholar cans understand the content of the present invention and implement it accordingly, and it is not intended to limit the scope of the present invention.It is all according to the present invention
