Embodiment
As shown in Figures 1 to 6, a kind of children trolley described in the utility model, comprises vehicle frame, front component 1, the wheel assembly 2 with expansion state and folded state and vehicle frame is locked in the locking gear (not shown) of expansion state and folded state. Rear wheel support 4, cushion rod 5, push rod 6 and the fork 7 that described vehicle frame comprises the front wheel support 3 that is connected with described front component 1 of bottom, bottom is 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 by pivot and front wheel support 3 and rear wheel support 4 respectively, and described fork 7 is rotationally connected by pivot and push rod 6 and rear wheel support 4 respectively. The length of described rear wheel support 4 can regulate. Described rear wheel support 4 is provided with elasticity device 11, and when described vehicle frame folding, described rear wheel support 4 shrinks, and described elasticity device 11 is by compress energy storage; When described vehicle frame launches, described elasticity device 11 fault offset makes rear wheel support 4 extend, and vehicle frame is wholly or partly automatic expansion. When vehicle frame is in expansion state, the elongation of described rear wheel support 4 launches and props 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 overturns backward around front wheel support 3 under the drive of rear wheel support 4, rear wheel support 4 is near drawing under the drive of push rod 6 for described front wheel support 3, fork 7 and cushion rod 5, and described front component 1 is drawn close side by side with wheel assembly 2 and children trolley support stood on ground.
Described rear wheel support 4 comprises the first rod member 8, the 2nd rod member 9 and is installed in the pedal 10 of the 2nd 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 2nd rod member 9 is connected with wheel assembly 2. Described first rod member 8 and the 2nd rod member 9 are slidably connected, and described first rod member 8 and the 2nd rod member 9 arrange on the same line, and described first rod member 8 can slide along the length direction of the 2nd rod member 9. In the present embodiment, described 2nd rod member 9 is the tubular rod of inner hollow, and described first rod member 8 is located in the 2nd rod member 9 and can slide in the 2nd rod member 9, and the top of described first rod member 8 is exposed outside the 2nd rod member 9. Described pedal 10 is fixedly connected with the first rod member 8. Concrete, the 2nd rod member 9 is offered the chute of the rod member wall of through 2nd rod member 9, the first rod member 8 and pedal 10 rivet by being located in chute. Described pedal 10 can move up and down in the 2nd rod member 9 outside. When pedal 10 moves downward, described first rod member 8 slides contraction in the 2nd rod member 9, and described rear wheel support 4 length shortens; When pedal 10 upwards moves, described first rod member 8 slides outside the 2nd rod member 9 and stretches out, and described rear wheel support 4 length is extended.
Described elasticity device 11 is arranged in the 2nd rod member 9, the bottom of described first rod member 8 is connected with described elasticity device 11, when described vehicle frame launches, first rod member 8 is extended by described elasticity device 11 fault offset to the 2nd rod member 9 extrapolation rear wheel support 4 of sening as an envoy to, and vehicle frame is wholly or partly automatic expansion.
In the present embodiment, described elasticity device 11 is pneumatic cushioning, is exerted pressure downwards by pedal 10, and described first rod member 8 slides in the 2nd rod member 9 and makes pneumatic cushioning compress energy storage, unclamping pedal 10, described pneumatic cushioning resets and promotes the first rod member 8 to stretch out outside the 2nd rod member 9.
Described first rod member 8 is positioned at the top of front wheel support 3 with the junction of 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 2nd 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 2nd 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 utility model, the locking gear that vehicle frame is locked in expansion state is the first locking gear, and the locking gear that vehicle frame is locked in folded state is the 2nd locking gear. When the children trolley that will be in expansion state is folding, first the first locking gear is unlocked, pin pushes pedals 10 moves downward, the first rod member 8 is driven to shrink back in the 2nd rod member 9, pneumatic cushioning is compressed, push rod 6 overturns backward, and rear wheel support 4 is near drawing under the drive of push rod 6 for front wheel support 3, seat post 5 and fork 7, and described front component 1 is drawn close side by side with wheel assembly 2 and children trolley support stood on ground. By the 2nd locking gear locking, so far whole folding process completes.
When the children trolley being in folded state is launched, 2nd locking gear is unlocked, first rod member 8 stretches out outside the 2nd rod member 9 under the effect of pneumatic cushioning, first rod member 8 drives push rod 6 turning unfolding forward, before simultaneously, wheel support 3, seat post 5 and fork 7 launch under the drive of push rod 6, finally by the first locking gear locking, so far whole expansion process completes.
From above-mentioned, the folding of children trolley can easily realize by stepping on pressure pedal 10, and folding mode is novel and step is simple. Expansion process can be launched automatically by pneumatic cushioning, laborsaving convenience.
First rod member 8 and the 2nd rod member 9 can also be changed by the utility model on the basis of above-described embodiment, the tubular rod that described first rod member 8 is particularly set to inner hollow, described first rod member 8 is set on the 2nd rod member 9 and can slide on the 2nd rod member 9 simultaneously. This kind of mode also can realize the function of the structure of children trolley as described in above-described embodiment.
As mentioned above, it is necessary, we are illustrated according to objective of the present utility model completely, but the utility model is not limited to above-described embodiment and implementation method. The practitioner of correlative technology field can carry out different changes and enforcement in the scope that technological thought of the present utility model is permitted.
