Seven axis 17 are located at the lower section of the second axis 12 on back stay 2.The connecting rod 4 can be integrated the bar of setting, be also possible to two
Root or plurality of rods are fixed together and shape is integral.
Above-mentioned first axle 11, the second axis 12, third axis 13, the 4th axis 14, the 5th axis 15, the 6th axis 16 and the 7th axis 17
Axial line it is parallel each other, i.e., under vehicle frame unfolded state, the axial line of above-mentioned each shaft is not overlapped mutually.
In this way, constituting a deformable mechanism, preceding branch between front support rod 1, connecting rod 4, push rod lower beam 3a and first connecting rod 5
Also a deformable mechanism is constituted between bar 1, connecting rod 4, back stay 2 and second connecting rod 6, passes through above-mentioned two deformable mechanism
In each rod piece relative rotation, can realize the expansion and folding of side stand.In the present embodiment, on each side side stand, under push rod
It is additionally provided between bar 3a and connecting rod 4 for by the locking joint 7 of the opposite locking of the two, when which locks, above-mentioned two
A deformable mechanism locks, and can so lock vehicle frame in the deployed state.When specific setting, can will locking joint 7 with
8 linkage of unlocking of push rod locking piece it is arranged, after the unlock of push rod locking piece 8, push rod upper boom 4b is driven to turn with respect to push rod lower beam 4a
It is unlocked locking joint 7.
Specifically, referring to shown in Fig. 1 to Fig. 3, connecting rod 4 includes the preceding bar portion 4a gradually extended from front to back to updip,
And incline gradually downward backward the rear rod portion 4b of extension from the upper end of preceding bar portion 4a, one is formed between preceding bar portion 4a and rear rod portion 4b
Angle, the lower end of preceding bar portion 4a are connected to the top of front support rod 1 by first axle 11, and the lower end of rear rod portion 4b passes through second
Axis 12 is connected to the top of back stay 2, preceding bar portion 4a and the joint rear rod portion 4b and is connected to push rod lower beam 3a by third axis 13
On.When vehicle frame is in unfolded state, preceding bar portion 4a and front support rod 1 extend along same length direction, rear rod portion 4b and back stay 2
Extend along same length direction.
Front support rod 1 includes preceding club shaft 1a, and the connector rod 1b upwardly extended from the upper end of preceding club shaft 1a, connecting rod
Before 4 one end is rotationally connected to by first axle 11 on the upper end of club shaft 1a, the front of second connecting rod 6 passes through the 6th
Axis 16 is rotationally connected to the upper end of connector rod 1b.Further, connector rod 1b is set on the inside portion of preceding club shaft 1a,
When vehicle frame is in unfolded state, two piece-root grafting head rod 1b of the left and right sides are located in left-right direction between the connecting rod 4 of two sides, vehicle
Structure is more simple and beautiful from the side when frame is unfolded.
The vehicle frame further includes being set to the front rail 30 between 1 lower part of two sides front support rod, being set between 2 lower part of two sides back stay
Rear transverse rod 40, and the middle cross bar 50 between two sides second connecting rod 6.The second connecting rod 6 of two sides is located in left-right direction
Between the connecting rod 4 and back stay 2 of two sides, which can be used as a bar, under vehicle frame unfolded state, second connecting rod 6 with
Stable triangular structure is formed between front support rod 1, back stay 2 and connecting rod 4, stability is very good, can bear biggish
Load；The push rod 3 of two sides is located at the outside of two lateral connector bars 4 in left-right direction, and two sides push rod upper boom 3b is wholely set in opening
U-shaped directed downwardly.
In this way, as shown in Figure 1 and Figure 2, connecting rod 4 connects when the vehicle frame of the present embodiment children trolley is locked in unfolded state
Between front support rod 1 and back stay 2, so that constituting one three between front rod 4, front support rod 1, back stay 2 and second connecting rod 6
Angular structure, the body frame structure for automotive under unfolded state is very succinct, and aesthetics is good.
It is shown in Figure 3 when needing to get up the vehicle frame folding, push rod upper boom 3b is being rotated relative to push rod lower beam 3a
After folding, push rod 3 is driven to overturn forward, can make each rod piece in two deformable mechanisms above-mentioned to relatively rotate, specifically
For, the overturning of push rod 3 drives first connecting rod 5 to move backward, so that front support rod 1 is turned over around first axle 11, front component
10 move backward；Meanwhile second connecting rod 6 travels forward under the action of front support rod 1, drive back stay 2 around the second axis 12 to
Preceding overturning wheel assembly 20 travels forward, that is, front support rod 1 moves toward one another along the longitudinal direction with back stay 2, meanwhile, first connecting rod
5, gradually stacking is collapsed along the vertical direction for second connecting rod 6, connecting rod 4 and push rod 3, until forming state as shown in Figure 4, rear wheels
Part 20 is in preceding and front component 10 rear.
In the folded vehicle frame, each rod piece closely collapses together along the vertical direction, and compact-sized, volume is very
It is small, the especially folding rear carriage dimensions length having a size of front support rod 1 Yu back stay 2 in the front-back direction, rather than in traditional vehicle
The summation of front support rod 1 and preceding bar portion 4a length, thus compared to traditional vehicle for, folded length dimension significantly contracts
It is short, it is easier to obtain lesser volume after vehicle frame folding, facilitate the daily storage of user and carry.
When opening vehicle frame, it is only necessary to pull push rod upper boom 3b, that is, may make rod piece all on vehicle frame relatively rotates to beat
It opens, operation very simple is convenient.
The above embodiments are only for explaining the technical ideas and features of the present invention, and its object is to allow be familiar with technique
Personage can understand the content of the utility model and implement accordingly, do not limit the protection scope of the present invention.
All equivalent change or modifications according to made by the spirit of the present invention essence, should all cover the protection scope of the utility model it
It is interior.
