It is rotatablely connected by the second axis 9b；Seat bar 7, seat bar 7 extends along the longitudinal direction under the unfolded state of vehicle frame, the front of seat bar 7
It is rotatablely connected with front support rod 4 by third axis 9c, the rear portion of seat bar 7 and the lower part of push rod 6 are rotatablely connected by the 4th axis 9d；?
Under the unfolded state of vehicle frame, the second axis 9b is located at the top of the 4th axis 9d.
Specifically, the lower part of the front support rod 4 of every side is equipped with front component 1 in the present embodiment, under the back stay 5 of every side
Portion is equipped with wheel assembly 2.It is of course also possible to which one group of front component 1 is arranged in vehicle frame bottom front, vehicle frame bottom rear portion is arranged two groups
Wheel assembly 2.
Specifically, locking mechanism includes the expansion locking being arranged at the rotation connection of push rod 6 and seat bar 7 in the present embodiment
Mechanism 3, when expansion locking mechanism 3 locks, front support rod 4, back stay 5, seat bar 7 and push rod 6 are locked, so that two sides
Side stand is locked in the deployed state, naturally it is also possible to which expansion locking mechanism 3 is arranged in turn of front support rod 4 and back stay 5
Dynamic junction, is perhaps arranged at the rotation connection of front support rod 4 and seat bar 7 or is arranged in the rotation of push rod 6 Yu back stay 5
Junction.
When vehicle frame is given folding by unfolded state, after the side stand unlock of two sides, pressing push rod 6 makes it around the 4th axis
9d is rotated clockwise, and the lower part of push rod 6 drives the rear portion of seat bar 7 to move upwards, and the front of seat bar 7 drives front support rod 4 to prop up backward
The rotation of bar 5 is drawn close, so that the mutually rotation of front support rod 4, back stay 5, seat bar 7 is drawn close, finally as shown in Fig. 3 ~ Fig. 4, is realized
The folding of vehicle frame, the 4th axis 9d is located at the top of the second axis 9b at this time, and push rod 6 is collapsed in the rear of back stay 5, and seat bar 7 is located at
Between front support rod 4 and back stay 5, two groups of wheel assemblies 2 are collapsed in left-right direction between two groups of front components 1, moreover, relatively
In the mode for being directly rotatablely connected front support rod 4 and main body bar 5b, the setting of connecting rod 5a further shortens vehicle frame folding shape
Whole height under state, easily facilitates transport and storage.
Embodiment 2
As shown in Fig. 4 ~ Figure 12, the side stand of the present embodiment every side on the basis of embodiment 1 is additionally arranged a commutation handle 8, often
The lower part of the commutation handle 8 of side and ipsilateral push rod 6 are rotatablely connected by the 5th axis 9e, herein, the 4th axis 9d and the 5th axis 9e
Axial line be overlapped or the 4th axis 9d is coaxial with the 5th axis 9e, the children trolley have it is preceding to use state with after
To use state, as shown in Fig. 5 ~ Fig. 6, under forward direction use state, commutation handle 8 tilts extension from front to back and upwards, changes
It is located at the rear of seat bar 7 to the upper end of handle 8；As shown in Fig. 7 ~ Fig. 8, rear under use state, commutation handle 8 is from back to front
And inclination extends upwards, the upper end of commutation handle 8 is located at the front of seat bar 7, is additionally provided on vehicle frame and locks for the handle 8 that will commutate
Forward direction use state or after to use state commutation locking piece (not shown).
Specifically, commutation locking piece setting commutation handle 8 on, under forward direction use state, commutation locking piece with it is described
6 mutually locking of push rod；Rear under use state, commutation locking piece and 4 mutually locking of front support rod.
Specifically, commutation handle 8 includes upper commutation handle 8a, lower commutation handle 8b, and upper commutation handle 8a and lower commutation push away
8b is rotatablely connected by the 6th axis 9f, wherein being provided with handle locking mechanism at the 6th axis 9f, it is preferable that handle locks machine
It is provided with unlock operating parts on structure, is additionally provided with linkage of unlocking mechanism between handle locking mechanism and expansion locking mechanism 3, the connection
Hauling rope specifically can be used in dynamic unlocking mechanism, unlocks handle locking mechanism by operation unlock operating parts, just can pass through two
Linkage of unlocking mechanism between person is unlocked locking mechanism 3 is unfolded, to realize the unlock of two sides side stand.
It is collateral in two sides to use state before being first converted to children trolley when vehicle frame is given folding by unfolded state
Frame unlock after, upper commutation handle 8a is flipped up counterclockwise around the 6th axis 9f, then down by pressure commutate handle 8b make its around
5th axis 9e is rotated clockwise, and push rod 6 is driven to rotate clockwise down together, under the folded state of vehicle frame, upper commutation handle
At the rotation connection of 8a and lower commutation handle 8b and wheel assembly 2 forms the support to vehicle frame, so that the vehicle frame can
It supports oneself after folding.
