Detailed description of the invention
nullSuch as Fig. 1、Shown in Fig. 2，This foldable baby stroller includes upper push-rod 9、Lower push-rod 7、Front-wheel support 4、Pedal 1、Seat bar 8、Lower link 2、Back link 6、Basket rod 5、Rear wheel support 3，It is characterized in that，Described front-wheel support 4、Pedal 1、Basket rod 5 connects into mutual rotating relation，The front end of described lower link 2 is flexibly connected with pedal 1，Described basket rod 5 is flexibly connected with described rear wheel support 3，Described back link 6 is flexibly connected with described lower push-rod 7 and seat bar 8 respectively，Described front-wheel support 4 respectively with lower push-rod 7、Seat bar 8 is flexibly connected，Described front-wheel support 4、Seat bar 8、Back link 6、Basket rod 5、Rear wheel support 3 is interconnected to rotating five-bar mechanism relation，Described seat bar 8、Front-wheel support 4、Pedal 1、Lower link 2、Back link 6 is interconnected to rotating five-bar mechanism relation，Described rear wheel support 3 upper end coaxially connected with the rear end of back link 6 lower end and described lower link become mutual rotating relation.
As shown in Figure 2, it it is the perspective view of this foldable baby stroller vehicle frame its fully unfolded position, with reference to Fig. 2, lower link 2 includes lower link singletree 2a and lower link montant 2b, and lower link 2 rear end is coaxially rotatably connected with rear wheel support 3 upper end and back link 6 lower end.
As in figure 2 it is shown, foot-operated singletree 1a and pedal 1c locks car locking seat 1b jointly, when vehicle frame launches；
As it is shown in figure 1, return the vehicle to the garage and knock off, sliding sleeve 27 slides in the opening chute of vehicle seat 1b automatically, thus locking whole vehicle frame.
As in figure 2 it is shown, seat bar 8 includes a bar 8a and seat cushion singletree 8b, present bar 8 front end uses rivet interlacement with front-wheel support 4, forms rotation relation.
As shown in Figure 1, upper push-rod 9 and lower push-rod 7 use rivet 23 to be rotatably connected, there is geared lock mechanisms inside, dissoluble locking joint (diagram does not section out) it is provided with in fig. 2 as seen between upper push-rod 9 and lower push-rod 7, when locking joint and being in the lock state by gear movement, locking mechanism stops relatively rotating between upper push-rod 9 and lower push-rod 7.
Foldable baby stroller also includes front fluffy bar 10, and front fluffy bar 10 is installed in rotation on described upper push-rod joint, can rotate with upper push-rod time folding.
Foldable baby stroller also includes front handrail 12, front handrail 12 and lower push-rod 7 and uses with front-wheel support 4 rivet interlacement to become mutual rotating relation.
Foldable baby stroller also includes lower limb tube 13, and lower limb tube 13 utilizes rivet 25 to connect on present bar 8, connects into mutual rotating relation.
Foldable baby stroller also includes back support bar 11, and back support bar 11 and seat bar 8 utilize back support bar connection rivet 26 to connect into mutual rotating relation.
Foldable baby stroller also includes front-wheel 14 and trailing wheel 15, and in the present embodiment, front-wheel 14 is arranged at pedal 1 lower end, and trailing wheel 15 is arranged at rear wheel support 3 lower end.
As shown in Figure 1 and Figure 2, it is in the lock state but without the locking joint between upper push-rod time folding 9 and lower push-rod 7 at doll carriage, the sliding sleeve 27 that returns the vehicle to the garage and knock off on lower link 2 is also stuck in the draw-in groove of the car locking seat 1b below pedal 1 simultaneously, thus ensureing that frame locking mechanism is in the lock state.
Refer to Fig. 1, lower link 2 is provided with the locking mechanism controlling the locking of whole vehicle frame or released state, described locking mechanism includes being slidingly arranged at returning the vehicle to the garage and knock off handle 19 and the sliding sleeve that returns the vehicle to the garage and knock off that is slidingly arranged on lower link on lower link 2, and the handle 19 that returns the vehicle to the garage and knock off can control to return the vehicle to the garage and knock off by internal connecting rods the slip of sliding sleeve 27.
During folding operation, first the direction of front fluffy bar 10 upwards push rod 9 is rotated, then the locking joint between upper push-rod 9 and lower push-rod 7 being unlocked state again, then upper push-rod 9 is turned to state shown in Fig. 3-4 to back link 6 direction, now go-cart is in first step folded state.
Following Xian Ba bis-road insurance 29(is as shown in Figure 4) sliding to such as figure right direction releases two road safety positions, then mention with 19 car loads of handle that return the vehicle to the garage and knock off, make pedal 1 downward, then exert oneself downward whipping vehicle frame, under action of gravity, upper push-rod 9, back link 6, lower push-rod 7 can according to the mutual rotation relation set, rotate towards front-wheel support 4 direction, front-wheel support 4 front end and pedal 1 upper end and basket rod 5 are along with mutual rotating relation simultaneously, can naturally droop and drive rear wheel support 3 to be rotated down along rivet 18 with the reason of gravity, so that doll carriage is rapidly achieved Fig. 5, return the vehicle to the garage and knock off shown in Fig. 6 state.
Folding baby go-cart may proceed to, along the mutual rotation relation set, fold into the folded state that returns the vehicle to the garage and knock off such as Fig. 7, Fig. 8 under such as Fig. 5, Fig. 6 state.
nullIn sum，Compared with prior art，Folding pushing vehicle carriage provided by the invention，Utilize following principle: " upper push-rod、Lower push-rod、Front-wheel support、Pedal、Seat bar、Lower link、Back link、Basket rod、Rear wheel support，It is characterized in that，Described front-wheel support、Pedal、Basket rod connects into mutual rotating relation，The front end of described lower link is flexibly connected with pedal，Described basket rod is flexibly connected with described rear wheel support，Described back link is flexibly connected with described lower push-rod and seat bar respectively，Described front-wheel support is respectively and lower push-rod、Seat bar is flexibly connected，Described front-wheel support、Seat bar、Back link、Basket rod、Rear wheel support is interconnected to rotating five-bar mechanism relation，Described seat bar、Front-wheel support、Pedal、Lower link、Back link is interconnected to rotating five-bar mechanism relation，Described rear wheel support upper end coaxially connected with the rear end of back link lower end and described lower link become mutual rotating relation." achieving a fold mechanism simply, volume after folding is less, it is easy to carry, easily manufactured, with low cost, vehicle frame easy to use.
