The technical solution of the utility model is further elaborated with specific embodiment below in conjunction with the accompanying drawings.
Referring to the children trolley shown in Fig. 1 to Fig. 5, it includes the vehicle frame with deployed condition and folded state, located at this
The wheel assembly of bottom of frame, and for the locking mechanism by vehicle frame locking in the deployed state.
Vehicle frame includes fore-stock 1, after-poppet 2, push rod 3 and seat frame 4, wherein, fore-stock 1 from front to back gradually prolong by updip
Stretch, the bottom of push rod 3 is connected with the top phase pivot of fore-stock 1, the upper pivot of after-poppet 2 is connected on push rod 3, seat frame
4 front portion is pivotally connected on fore-stock 1 and its rear portion is then pivotally connected on after-poppet 2.
The vehicle frame also includes connecting rod 5, and the connecting rod 5 is connected to preceding branch located at the top of seat frame 4, the upper pivot of connecting rod 5
On frame 1, the lower pivot of connecting rod 5 is connected with sliding part 6, and the sliding part 6 can along the longitudinal direction be slidably arranged in seat frame 4
On.Referring to shown in each accompanying drawing, on the vehicle frame, the front portion of seat frame 4 is pivotally connected on fore-stock 1 by first axle 7, connecting rod 5
Upper end be pivotally connected on fore-stock 1 by the second axle 8, the bottom of push rod 3 and the top of fore-stock 1 pass through the 3rd axle 9
Phase pivot is connected.In the present embodiment, between the second axle 8 is located at the axle 9 of first axle 7 and the 3rd on fore-stock 1.So, vehicle frame is worked as
During folding, sliding part 6 along the forward slip of seat frame 4 cause vehicle frame on fore-stock 1, seat frame 4, connecting rod 5, after-poppet 2 and
Push rod 3 is relatively rotated and gradually drawn in together.
In other examples, also can be by the 3rd axle 9 and the coaxial connection of the second axle 8.So, can equally realize and this
The vehicle frame identical folding mode of embodiment.
Specifically, in the present embodiment, fore-stock 1 have be divided into the left and right sides and from front to back gradually updip extend
Two front support rods 11, front rail 12 is fixedly connected between the bottom of both sides front support rod 11 so that fore-stock 1 is in opening up
U-shaped bar, the left and right sides bottom of fore-stock 1 is respectively equipped with one group of front-wheel 10.After-poppet 2 have be divided into the left and right sides and
Two vertically extending back stays 21, are fixedly connected with rear transverse rod 22, after-poppet 2 between the bottom of both sides back stay 21
Left and right sides bottom be respectively equipped with one group of trailing wheel 20.Push rod 3 is in downward opening U-shaped bar, and it has and is divided into the left and right sides
Two push rod side levers 31, the top of bottom and the homonymy front support rod 11 of the push rod side lever 31 per side is by the phase pivot of the 3rd axle 9
Axle is connected.
Seat frame 4 has the cross bar for being divided into two seat bars of the left and right sides and being fixedly connected between the seat bar of both sides, often
The seat bar of side is respectively provided with and extends to provide the sitting portion 41 of sitting support, bend downwards from the rear portion in sitting portion 41 along the longitudinal direction
The connecting portion 42 of extension.The front portion in sitting portion 41 is pivotally connected on homonymy front support rod 11 by first axle 7, under connecting portion 42
Portion is pivotally connected on the bottom of homonymy back stay 21.
Correspondingly, connecting rod 5 also has and is divided into two of the left and right sides, and the top per side connecting rod 5 passes through the pivot of the second axle 8
It is connected on the front support rod 11 of homonymy；What sliding part 6 was used is sliding sleeve, and the sliding sleeve 6 is arranged on present bar and can be along sitting portion 41
Length bearing of trend slide anteroposterior.
In the present embodiment, locking mechanism is included located at the locking for being used to lock both between sliding part 6 and seat frame 4
Part, specifically, one group of locking piece is equipped with the sliding sleeve 6 of both sides and the sitting portion 41 of corresponding side.Can by both sides sliding sleeve 6 it
Between set unblock carry hand（Not shown in figure）, so that operator can be by the locking piece solution of both sides in lifting unblock carry hand
Lock, while so that sliding sleeve 6 is along the forward slip of seat frame 4, and then so that each rod member on vehicle frame is relatively rotated and gradually drawn in
Together.
To sum up, when the children trolley is locked in deployed condition, as shown in Figure 1 and Figure 2, push rod 3 is with fore-stock 1 along same length
Degree direction extends, on the vehicle frame left and right sides, triangle structure between front support rod 11, seat bar and connecting rod 5, front support rod 11,
Also triangle structure between push rod side lever 31, back stay 21 and seat bar so that vehicle frame has good rigidity and stability,
So as to the sitting support of stabilization can be provided.
Shown in Figure 3 when needing to get up children trolley folding, operator only need to lift unblock from the front of go-cart
Carry hand and both sides sliding sleeve 6 is unlocked and makes it along the forward slip of seat frame 4, push rod 3 is turned over because of deadweight rearwardly towards after-poppet 2
Turn, connecting rod 5 and seat frame 4 rotate and so that fore-stock 1, after-poppet 2 and push rod 3 gradually draw in together along the longitudinal direction.Most
Eventually, each rod member on vehicle frame closely draws in together, forms state, the body frame structure for automotive ten after folding as shown in Figure 4, Figure 5
That divides is compact smooth.
When needing to open and use the children trolley, operator only needs to lift push rod 3, just may be such that each bar on vehicle frame
Part is relatively rotated and sliding sleeve 6 is slided backward along seat frame 4, is locked automatically when sliding sleeve 6 slides into the latched position on seat frame 4
Fixed, vehicle frame is automatically locked under the open mode, and operation also very facilitates.
