Detailed description of the invention
as shown in Figures 1 to 6, a kind of children trolley of the present invention, comprises vehicle frame, front component 1, the wheel assembly 2 with deployed condition and folded state and vehicle frame is locked in the blocking device (not shown) of deployed condition and folded state.Rear wheel support 4, cushion rod 5, push rod 6 and fork 7 that the front-wheel support 3 be connected with described front component 1 bottom described vehicle frame comprises, bottom are connected with described wheel assembly 2.
the top of described front-wheel support 3 is connected by pivot with the bottom of push rod 6.Described push rod 6 is rotationally connected by pivot and rear wheel support 4.Described cushion rod 5 is rotationally connected respectively by pivot and front-wheel support 3 and rear wheel support 4, and described fork 7 is rotationally connected respectively by pivot and push rod 6 and rear wheel support 4.The length of described rear wheel support 4 can regulate.Described rear wheel support 4 is provided with springing 11, and when described vehicle frame folding, described rear wheel support 4 shrinks, and described springing 11 is by compress energy storage; When described vehicle frame launches, described springing 11 fault offset makes rear wheel support 4 extend, and vehicle frame is wholly or partly Automatic-expanding.When vehicle frame is in deployed condition, described rear wheel support 4 extends and launches and prop up push rod 6, and described push rod 6 is vertical along the bearing of trend support of front-wheel support 3; When vehicle frame is in folded state, described rear wheel support 4 shrinks, described push rod 6 is turned over around front-wheel support 3 under the drive of rear wheel support 4, described front-wheel support 3, fork 7 and cushion rod 5 draw in rear wheel support 4 is close under the drive of push rod 6, and described front component 1 is drawn close side by side with wheel assembly 2 and supportted by children trolley and stands on the ground.
described rear wheel support 4 comprises the first rod member 8, second rod member 9 and is installed in the pedal 10 of the second rod member 9 outside.The top of described first rod member 8 is rotationally connected by pivot and push rod 6, and the bottom of described second rod member 9 is connected with wheel assembly 2.Described first rod member 8 and the second rod member 9 sliding block joint, described first rod member 8 and the second rod member 9 arrange on the same line, and described first rod member 8 can slide along the length direction of the second rod member 9.In the present embodiment, described second rod member 9 is the tubular rod of inner hollow, and described first rod member 8 to be located in the second rod member 9 and can to slide in the second rod member 9, and the top of described first rod member 8 is exposed outside the second rod member 9.Described pedal 10 is fixedly connected with the first rod member 8.Concrete, the second rod member 9 offers the chute of the rod member wall of through second rod member 9, the first rod member 8 and pedal 10 are by being located in the rivet in chute.Described pedal 10 can at the outside up-and-down movement of the second rod member 9.When pedal 10 moves downward, described first rod member 8 slides contraction in the second rod member 9, described rear wheel support 4 contraction in length; When pedal 10 upward movement, described first rod member 8 slides and stretches out outside the second rod member 9, described rear wheel support 4 length elongation.
described springing 11 is arranged in the second rod member 9, the bottom of described first rod member 8 is connected with described springing 11, when described vehicle frame launches, first rod member 8 extends to the second rod member 9 extrapolation rear wheel support 4 of sening as an envoy to by described springing 11 fault offset, and vehicle frame is wholly or partly Automatic-expanding.
in the present embodiment, described springing 11 is air bellow, exerts pressure downwards to pedal 10, and described first rod member 8 slides and makes air bellow compress energy storage in the second rod member 9, unclamp pedal 10, described air bellow reset promotion first rod member 8 stretches out outside the second rod member 9.
described first rod member 8 is positioned at the top of the junction of front-wheel support 3 and push rod 6 with the junction of push rod 6.The front portion of described cushion rod 5 is connected by pivot with front-wheel support 3, and the rear portion of described cushion rod 5 is connected by pivot with the second rod member 9, and the junction of described cushion rod 5 and front-wheel support 3 is lower than the junction of described push rod 6 with front-wheel support 3.The front portion of described fork 7 is connected by pivot with push rod 6, the rear portion of described fork 7 is connected by pivot with the second rod member 9, and the junction of described fork 7 and push rod 6 is between the junction and the junction of front-wheel support 3 and push rod 6 of the first rod member 8 and push rod 6.
in the present invention, blocking device vehicle frame being locked in deployed condition is the first blocking device, and blocking device vehicle frame being locked in folded state is the second blocking device.When the children trolley being in deployed condition is folded, first the first blocking device is unlocked, pin pushes pedals 10 moves downward, the first rod member 8 is driven to shrink back in the second rod member 9, air bellow is compressed, push rod 6 is turned over, and front-wheel support 3, seat post 5 and fork 7 draw in rear wheel support 4 is close under the drive of push rod 6, and described front component 1 is drawn close side by side with wheel assembly 2 and supportted by children trolley and stands on the ground.By the second blocking device locking, so far whole folding process completes.
when the children trolley being in folded state is launched, second blocking device is unlocked, first rod member 8 stretches out outside the second rod member 9 under the effect of air bellow, first rod member 8 drives push rod 6 turning unfolding forward, front-wheel support 3, seat post 5 and fork 7 launch under the drive of push rod 6 simultaneously, finally by the first blocking device locking, so far whole expansion process completes.
from above-mentioned, the folding of children trolley can easily realize by jamming on pedal 10, and folding mode is novel and step is simple.Expansion process can Automatic-expanding by air bellow, laborsaving convenience.
first rod member 8 and the second rod member 9 can also change by the present invention on the basis of above-described embodiment, particularly described first rod member 8 is set to the tubular rod of inner hollow, simultaneously described first rod member 8 to be set on the second rod member 9 and can to slide on the second rod member 9.This mode also can realize the function of the structure of children trolley as described in above-described embodiment.
as mentioned above, we are illustrated according to aim of the present invention completely, but the present invention is not limited to above-described embodiment and implementation method.Different changes and enforcement is carried out in the scope that the practitioner of correlative technology field can permit at technological thought of the present invention.
