Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model preferred embodiment is described in detail:
Below about in the definition in direction, be all when being in deployed condition according to this Foldable baby stroller structure, children's sitting viewed direction in cart structure is defined.
Foldable baby stroller structure as shown in Figures 1 to 5, mainly comprises stroller frame 1, front component 2, wheel assembly 3 and the lockout mechanism for stroller frame 1 being locked in expanded position with expanded position and folding position.
Wherein, front component 2 and wheel assembly 3 include two symmetrically arranged rollers, be connected to pivot shaft between roller, and their roller axial line parallels; Wheel assembly 3 has two groups, and their correspondences arrange and its axial line is on same straight line.
Stroller frame 1 comprises stretcher 4, is arranged at side stand and the back brace cross bar 15 of stretcher 4 both sides.Stretcher 4 is arranged on front component 2, and the fixed form of it and front component 2 can be the pivot shaft central authorities being vertically fixed on front component 2; Its both sides are respectively equipped with symmetrical cavity 41.
The side stand of every side includes after poppet 11, push rod 12, front frame 13 and seat post 14.The bottom of after poppet 11 is provided with wheel assembly 3.The bottom of push rod 12 is connected with the top phase pivot of after poppet 11, and such push rod 12 can relatively rotate to after poppet 11; And its top can be directly connected with the top of opposite side push rod 12 or be connected by extra cross bar, certainly in order to conserve space, the rod member that push rod 12 can be designed to expansion link or can fold.The bottom of front frame 13 is arranged in the cavity 41 of stretcher 4, and the cross-sectional area of cavity 41 is greater than the cross-sectional area of corresponding front frame 13, be separated to prevent front frame 13 and cavity 41, rivet can be selected to be fixed, and such front frame 13 can carry out activity to a certain degree in cavity 41 scope; The top of front frame 13 is connected with push rod 12 phase pivot, the position of connecting portion between the upper and lower of push rod 12 (distance on connecting portion and push rod 12 top is greater than the distance of itself and push rod 12 bottom), makes front frame 13 and push rod 12 to relatively rotate.Seat post 14 is connected with front frame 13, after poppet 11 phase pivot respectively, and wherein the junction of it and front frame 13 is near seat post 14 front end, has certain distance with the junction of after poppet 11 far from its rear end; And seat post 14 is combined by traditional seat post and basket rod, its front end is connected with reclinate curve, the angle of curve and seat post 14 shaft is approximately 90 °, the junction of it and after poppet 11 upwards bends to its rear end, namely seat post 14 is the rod member of bending, deduct the bar group of unnecessary burden like this, on the one hand made go-cart integral structure stability high, baby can have been improved on the other hand and be sitting in comfort level in this cart structure.In addition, push rod 12 bottom is connected with after poppet 11 upper pivot, front frame 13 top is connected with push rod 12 phase pivot, seat post 14 is connected with front frame 13, after poppet 11 phase pivot respectively, and this cart structure can be folded in the longitudinal direction.As shown in Figure 1, when stroller frame 1 is in expanded position, seat post 14 and the point of connection of front frame 13 and the distance on ground are greater than seat post 14 and the point of connection of after poppet 11 and the distance on ground, and namely seat post 14 and the point of connection of front frame 13 are higher than the point of connection of seat post 14 with after poppet 11.
Back brace cross bar 15 comprises two rear poles 151, and they mutually intersect and connect at infall phase pivot.The bottom of rear pole 151 is connected with after poppet 11 phase pivot of side (junction be positioned at above wheel assembly 3 nearby), its top then rotates with seat post 14 rear end of opposite side and is connected, after stroller construction unlocks, the contraction of back brace cross bar 15 is utilized to combine the front frame 13 be movably arranged in cavity 41 like this, what can realize that stroller construction carries out to a certain degree in the lateral direction is folding, is conducive to saving its space taken.
In the present embodiment, lockout mechanism is the electric bell 16 of the junction being arranged on after poppet 11 and push rod 12, for locking after poppet 11 and push rod 12.Push rod 12 unlocks pulling buckle 17, only needing operation to unlock pulling buckle 17 in use can unlock electric bell 16, very convenient.Stroller frame 1 also comprises the tarpaulin rod assembly 5 be connected to rotationally between push rod 12, the installation of the parts such as sunshade on doll carriage.
This Foldable baby stroller structure deployed condition as depicted in figs. 1 and 2, when this cart structure folds by needs, first operation unblock pulling buckle 17 pairs of electric bells 16 unlock, and turn over before push rod 12 relatively front frame 13, subsequently/relative for after poppet 11 front frame 13 is moved forward, as shown in Figure 3 simultaneously.Then continue to turn over before push rod 12 relatively front frame 13, push rod 12 is folded, subsequently/continue simultaneously by after poppet 11 relatively front frame 13 move forward, and back brace cross bar 15 inwardly shunk, drive relatively rotating of seat post 14, after poppet 11 is folded, as shown in Figure 4 and Figure 5.In above-mentioned folding process, folding operation is very convenient, and Foldable baby stroller structure folds at its left and right directions (longitudinal direction) and fore-and-aft direction (transverse direction) both direction, makes the compact conformation after folding, takes up room little.When this go-cart launches to use by needs, be reversed along said process.
Above-described embodiment is only for illustrating technical conceive of the present utility model and feature; its object is to person skilled in the art can be understood content of the present utility model and implement according to this; protection domain of the present utility model can not be limited with this; all equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed within protection domain of the present utility model.
