Additionally, be additionally provided with footboard 18 between the bottom of the front support rod 1 of both sides, this footboard 18 can collateral in both sides
Folding is drawn the most in left-right direction in when frame is drawn close in left-right direction.It is additionally provided with between the back support bar 8 of both sides and can laterally open up
The backrest connecting rod assembly 19 opened or draw in, when the back support bar 8 of this backrest connecting rod assembly 19 and both sides is collectively forming for children's ride-on
The back rest relied on.
On the children trolley of the present embodiment, described locking mechanism includes being located at described side lever sliding sleeve and described back stay 2
Between for by both lock locking piece (not shown).This locking piece can use the version that lock pin matches with lockhole.
It is equipped with above-mentioned locking piece between side lever sliding sleeve and the back stay 2 of both sides.It is provided with between the described locking piece of both sides for inciting somebody to action
First unblock handle 12 of locking piece synchronizing unlocking described in two.Described side lever sliding sleeve is provided with Foldable hanging hook 13, described back stay 2
Top be provided with hook base 14.When side lever sliding sleeve slides into the top of back stay 2, Foldable hanging hook 11 can be mutual with hook base 12
Coordinate hook that side lever sliding sleeve is fixedly located at the upper position of back stay 2.
Described children trolley also includes the sunshade bar 16 being located on push rod 3, described sunshade bar 16 and described push rod 3 pivot
Axle connects.When described vehicle frame is in deployed condition, described sunshade 16 bar stands on push rod 3；When described vehicle frame is in folding
During state, described sunshade bar 16 flips up draws close folding with push rod 3.
When children trolley is in deployed condition, locking mechanism locks.Two foundation struts 15 of bottom supporting rod assembly are opened up relatively
Opening, rear attached support component 17 is supported between the back stay 2 of both sides in left-right direction.On the side stand of every side, push rod 3 and front
Bar 1 relatively launches and substantially extends along same length direction, constitutes triangle between push rod 3, front support rod 1, back stay 2 and side lever 4
Shape structure.Another triangular structure is constituted between side lever 4, side lever connecting rod 5 and back stay 2.Seat bar 6 extend along the longitudinal direction and
It is stablely supported between front support rod 1 and side lever 4.Back support bar 8 stands in the top of a bar 6 by seat joint element for bar 10.Seat bar is even
Extension bar 7 extends the lower section launching present bar 6 along the longitudinal direction.
When this children trolley is folded by needs, first rear attached support component 17 is unlocked by operator, lifts then up
One unlocks handle 12 and is unlocked by the locking piece of both sides.This drives the side lever sliding sleeve of both sides sliding along back stay 2 simultaneously.Side lever 4
Rear end on sliding, while side lever connecting rod 5 under effect, side lever 4 drives front support rod 1 with back stay 2 the most gradually
Draw close.Push rod 3 is glided along front support rod 1 by push rod sliding sleeve 11 and gradually draws in relative to front support rod 1.Meanwhile, the rear end of seat bar 6 with
The most described front support rod 1 is flipped up and with seat bar sliding sleeve along side lever 4 length bearing of trend upward sliding.Seat bar 6 rear end by
The most up and drive back support bar 8 and seat bar connecting rod 7 the most up by seat joint element for bar 10, and then make a bar 6, seat bar
Connecting rod 7 back support bar 8 is drawn in together between front support rod 1 and back stay 2.Owing to seat bar connecting rod 7 is right with seat joint element for bar 10
The position-limiting action of back support bar 8 makes back support bar 8 stand in the top of seat post 6 after folding.When vehicle frame folding, side lever 4 rear end
Upper cunning and during driving front support rod 1 and back stay 2 the most gradually to draw close, before side lever 4 also drives bottom supporting rod 15
Hold the most up, mutually rotate between two bottom supporting rods 15 intersected and gradually draw close, so that the side stand of both sides gradually leans on
Hold together and realize the laterally folded of vehicle frame.
Finally, the front support rod 1 of every side, push rod 3, side lever 4, seat bar 6, back support bar 8 and back stay 2 draw in along the longitudinal direction
Together, wherein back support bar 8 stands on a bar 6 square block bar connecting rod 7 and withstands back support bar 8 by seat joint element for bar 10 and keep backrest
The position of bar 8.Bottom supporting rod assembly, rear attached support component 17, footboard 18 and backrest connecting rod assembly 19 draw the side stand in both sides in
Between.Now side lever sliding sleeve slides into the top of back stay 2, can be by by the hook that coordinates of Foldable hanging hook 13 and hook base 14
This vehicle frame is locked under this folded state.
To sum up, children trolley described in the utility model, back stay 2, side lever 4, side lever connecting rod 5 and the first sliding part 9
Forming slider-crank mechanism, front support rod 1, side lever 4, seat bar 6 and the second sliding part 20 form another slider-crank mechanism and make
The vehicle frame folding of children trolley is easy to operate, folds simple, and the body frame structure for automotive after folding is compact, small volume.Seat bar 6, backrest
Bar 8 and seat bar connecting rod 7 are connected each other by seat joint element for bar 10, and foldable rear seat bar connecting rod 7 and seat joint element for bar 10 are right
The position-limiting action of back support bar 8 makes children trolley fold rear backrest bar 8 can keep preferable structural rigidity and position relationship, it is possible to
Vehicle frame folding rear backrest bar 8 is effectively prevented to be stacked with miscellaneous part and affect the smooth degree that vehicle frame is opened.Vehicle frame simultaneously
Overall steadily of centre of gravity, vehicle frame can be supported oneself on the ground.
As it has been described above, we are illustrated fully according to objective of the present utility model, but this utility model not limits to
In above-described embodiment and implementation.The scope that the practitioner of correlative technology field can permit at technological thought of the present utility model
Inside carry out different changes and enforcement.
