The specific embodiment
By describing technology contents of the present utility model, structural attitude in detail, being realized object and effect, below in conjunction with embodiment and coordinate accompanying drawing to be explained in detail.
Foldable pushchair as shown in Figure 1, comprises vehicle frame 100, lower vehicle frame 200, rear vehicle frame 300, folding/unfolding joint 400 and folding device 500.Upper vehicle frame 100 comprises upper left vehicle frame 110, upper right vehicle frame 120, and upper left vehicle frame 110 and upper right vehicle frame 120 are symmetrical inversion L-type, and the upper end of upper left vehicle frame 110 and upper right vehicle frame 120 is articulated; Lower vehicle frame 200 comprises lower-left vehicle frame 210, bottom right vehicle frame 220, and lower-left vehicle frame 210 and bottom right vehicle frame 220 are symmetrical L-type, and the lower end of lower-left vehicle frame 210 and bottom right vehicle frame 220 is articulated; Rear vehicle frame 300 comprises left back vehicle frame 310, right back vehicle frame 320, and left back vehicle frame 310 and right back vehicle frame 320 are positioned at a side of vehicle frame 100 and lower vehicle frame 200, upper left vehicle frame 110 and lower-left vehicle frame 210 are connected in left back vehicle frame 310 by a folding/unfolding joint 400, upper right vehicle frame 120 and bottom right vehicle frame 220 are connected in right back vehicle frame 320 by a folding/unfolding joint 400, thus make vehicle frame 100 and lower vehicle frame 200 can be relative after vehicle frame 300 pivotables.Folding device 500 is between left back vehicle frame 310 and right back vehicle frame 320, and the pivotable of the upper vehicle frame 100 of restriction rear vehicle frame 300 relative to lower vehicle frame 200.Shown in Fig. 2-Figure 12, more specifically:
Shown in Fig. 2, the middle part of slide block 511 has sleeve joint hole 511a, and is socketed on slidably rear vehicle frame 300 by sleeve joint hole 511a; The both sides of slide block 511 outwards protrude out and form the first connecting portion 511b, difference pivot joint one pull bar 512 between two first connecting portion 511b and upper vehicle frame 100, lower vehicle frame 200; When upper vehicle frame 100 rear vehicle frame 300 pivotable relative to lower vehicle frame 200, drive pull bar 512, drive slide block 511 to slide along rear vehicle frame 300, thereby realize vertically folding or opening of Foldable pushchair.Further, as shown in Figure 2, between two first connecting portion 511b, form the locating piece 511c that protrudes from slide block 511 lateral walls.
The middle part of two poles 513 is articulated in P point, and the two ends of each pole 513 are connected to left back vehicle frame 310 and right back vehicle frame 320, and slide block 511 is connected in pole 513, and drives two poles 513 to be pivoted relative to each other.More specifically: the upper end of each pole 513 is connected to left back vehicle frame 310 or right back vehicle frame 320, between the lower end of each pole 513 and left back vehicle frame 310 or right back vehicle frame 320, be articulated with a dwang 515; Between each pole 513 and slide block 511, the upside in the middle part of two poles 513 pivoting point P, is articulated with connecting rod 514; Connecting rod 514 middle part relative to dwang 515 pivoting point P is symmetrical arranged.Further, shown in Fig. 2, slide block 511 protrudes out and forms the 3rd connecting portion 511d to described pole 513 directions, and the 3rd connecting portion 511d is used for connecting connecting rod 514.When the relatively rear vehicle frame 300 of slide block 511 slides, drive the connecting rod 514 of pivot joint with it, drive two poles 513 to be pivoted relative to each other, connecting rod 514 is pivoted relative to each other with dwang 515, make left back vehicle frame 310 and right back vehicle frame 320 near or away from, thereby realize the capable of transverse contracting of Foldable pushchair or open.
Connecting element 521 is socketed on rear vehicle frame 300 regularly, and connecting element 521 is positioned at the top of slide block 511; Engagement piece 522 is positioned at the relative inner of left back vehicle frame 310 and right back vehicle frame 320, and the upper end of engagement piece 522 is articulated in connecting element 521; The lower end of engagement piece 522 has hook part 522a, during the open-shaped state of Foldable pushchair, engagement piece 522 is near slide block 511, hook part 522a fastens the downside of locating piece 511c, the downside of connecting element 521 fastens in the upper side of slide block 511, limit the slip of the relatively rear vehicle frame 300 of slide block 511, make Foldable pushchair keep open configuration.Between engagement piece 522 and connecting element 521, below in engagement piece 522 with the articulated section of connecting element 521, elastic component 523 is set, elastic component 523 makes engagement piece 522 perseverances have the action trend that fastens locating piece 511c, thereby while making hook part 522a normal, keep fastening the state of locating piece 511c, make the open configuration of Foldable pushchair stable.
In conjunction with Figure of description 1-12, the process that folds of the utility model Foldable pushchair is described in detail:
When the open-shaped state of Foldable pushchair, as shown in Figure 3-Figure 5, after upper vehicle frame 100 is relative with lower vehicle frame 200, vehicle frame 300 opens, and upper vehicle frame 100 and lower vehicle frame 200 open and be located along the same line; The downside of connecting element 521 is resisted against the upper side of slide block 511, and elastic component 523 stretching engagement pieces 522 fasten in the downside of locating piece 511c hook part 522a, limits the position of slide block 511, thereby makes Foldable pushchair keep open configuration.
When folding Foldable pushchair, edge as shown in Figure 3 F1 direction lifts operating parts 530, the stressed pivotable of engagement piece 522 is away from slide block 511, elastic component 523 elastic deformations, hook part 522a discharges the effect that fastens to locating piece 511c, and as shown in Fig. 6-Fig. 9, upper vehicle frame 100 and lower vehicle frame 200 are under Action of Gravity Field, relatively, the downward pivotable of vehicle frame 300 folds, and can realize vertically folding of Foldable pushchair; Upper vehicle frame 100 and lower vehicle frame 200 vehicle frame 300 down slidings after pull bar 512 drives slide block 511 relative, slide block 511 drives pull bar 514 actions, the relative slide block 511 of pull bar 514 and pole 513 pivotables, pull two poles 513 near rear vehicle frame 300, two poles 513 are pivoted relative to each other and fold, so that Foldable pushchair capable of transverse contracting.Foldable pushchair is capable of transverse contracting and vertically folding simultaneously, and the Foldable pushchair after having folded is as shown in Figure 10-Figure 12.
Compared with prior art, the Foldable pushchair that the utility model provides, limits the slip of the relatively rear vehicle frame 300 of slide block 511, so that Foldable pushchair remains on deployed condition by snap fastener 520; While folding this Foldable pushchair, the location that operation snap fastener 520 discharges slide block 511, after upper vehicle frame 100 is relative under Action of Gravity Field with lower vehicle frame 200, vehicle frame 300 pivotables fold, Foldable pushchair is vertically being folded, via two pull bars 512, drive slide block 511 along rear vehicle frame 300 down slidings simultaneously; The slip of slide block 511 drives two pole 513 pivotables to fold, and makes Foldable pushchair at capable of transverse contracting.Simple in structure, easy to operate, only need to operate a snap fastener 520, in utilization, the gravity of vehicle frame 100 and lower vehicle frame 200 can drive Foldable pushchair to fold, and without user, expends larger strength.
Above disclosed is only preferred embodiment of the present utility model, certainly can not limit with this interest field of the utility model, and the equivalent variations of therefore doing according to the utility model claim, still belongs to the scope that the utility model is contained.
