Detailed description of the invention
below in conjunction with the drawings and specific embodiments, the technical solution of the utility model is further elaborated.
below about in the definition in direction, be all under being in deployed condition according to this children trolley, the direction observed when children's sitting is present on pocket frame 3 carries out defining, and fore-and-aft direction refers to the left and right directions in Fig. 3 to Fig. 5, and wherein left is front, after right is; Above-below direction refers to each above-below direction shown in the drawings.
see Fig. 1 ~ Fig. 5, a kind of children trolley, comprise there is deployed condition and folded state stroller frame, be located at wheel assembly bottom stroller frame and for by stroller frame locking lockout mechanism in the deployed state.Stroller frame comprises front frame 1, after poppet 2, seat pocket frame 3, sliding part 4, first connecting rod 5 and second connecting rod 6, seat pocket frame 3 at least comprise there is gusset and can for carry out enclose framework 31.Wheel assembly comprises the front-wheel 10 be located at bottom front frame 1 and the trailing wheel 20 be located at bottom after poppet 2.
after poppet 2 is connected with sliding part 4 rotationally, and sliding part 4 is located on front frame 1 along the length bearing of trend of front frame 1 slidably, and the top of after poppet 2 is rotatably connected on encloses on framework 31; One end of first connecting rod 5 is connected on sliding part 4 rotationally, and the other end of first connecting rod 5 is rotatably connected on second connecting rod 6; One end of second connecting rod 6 is rotatably connected on front frame 1, and its other end is rotatably connected on and encloses on framework 31.Like this, second connecting rod 6, first connecting rod 5, between sliding part 4 and front frame 1, just form a slider-crank mechanism, and enclose framework 31, second connecting rod 6, between front frame 1 and after poppet 2, just form a four-bar linkage.
in this stroller frame, front frame 1 and after poppet 2 intersect and arrange, and the position of sliding part 4 on front frame 1 is rotationally connected the below of position between second connecting rod 6 and front frame 1; The top of after poppet 2 and enclose being rotationally connected a little at second connecting rod 6 and enclose the below be rotationally connected between framework 31 a little between framework 31.When stroller frame is in deployed condition, the support of seat pocket frame 3 stands in the top of after poppet 2 and second connecting rod 6 and provides children sitting, encloses framework 31 and can serve as push rod for implementation.When this stroller frame is launched, by slider-crank mechanism locking or by four-bar linkage locking, stroller frame just can be made to lock in the deployed state.
shown in each accompanying drawing, in the present embodiment, this children trolley is three-wheel children trolley, the top that after poppet 2 comprises two back stays 21 laying respectively at the left and right sides and adapter shaft 22, two back stays 21 be connected between both sides back stay 21 is pivotally connected in the left and right sides of enclosing framework 31 respectively by the first axle 7.Front frame 1 is single cradling piece, and it is updip between the back stay 21 of both sides gradually from front to back.Sliding part 4 adopts and can slide up and down to be set in the sliding sleeve on front frame 1, and this sliding sleeve is directly pivotally connected on adapter shaft 22 using adapter shaft 22 as rotating shaft.
second connecting rod 6 adopts opening up U-shaped bar, the rearward end of front frame 1 offers the first mounting hole 11, the bottom of second connecting rod 6 is located in rotationally in the first mounting hole 11 of front frame 1 and overturns before and after relative front frame 1, and the upper end of second connecting rod 6 both sides is then pivotally connected in the left and right sides of enclosing framework 31 respectively by the second axle 8.Corresponding, first connecting rod 5 also adopts opening up U-shaped bar structure, sliding part 4 offers the second mounting hole 41, the bottom of first connecting rod 5 is located in rotationally in the second mounting hole 41 and overturns before and after relative sliding part 4, and the upper end of first connecting rod 5 both sides is pivotally connected in the middle part of second connecting rod 6 respectively.
in the present embodiment, lockout mechanism is arranged between sliding part 4 and front frame 1, for the relative position between lock slide 4 and front frame 1, when position between sliding part 4 and front frame 1 is locked by lockout mechanism, second connecting rod 6, first connecting rod 5, between sliding part 4 and front frame 1 form slider-crank mechanism position be locked, relative position between second connecting rod 6 and front frame 1 is locked, thus make to enclose framework 31, second connecting rod 6, the position of four-bar linkage that forms between front frame 1 and after poppet 2 be also locked.
front frame 1 is also provided with basket rod 9, for installing basketry to place with car article.
on seat pocket frame 3, enclose framework 31 in closed ring, enclose on framework 31 and be also provided with grab rail 32 and tarpaulin rod 33.
when stroller frame is in deployed condition, see Fig. 1 ~ Fig. 3, lockout mechanism between sliding part 4 and front frame 1 is in the lock state, second connecting rod 6, first connecting rod 5, the slider-crank mechanism formed between sliding part 4 and front frame 1 are in stable deployed condition, make to enclose framework 31, second connecting rod 6, between front frame 1 and after poppet 2, the four-bar linkage of formation is also in stable deployed condition, the support of seat pocket frame 3 stand in after poppet 2 and second connecting rod 6 on can supply children's sitting, and enclose framework 31 can for carrying out.
when stroller frame needs folding, see Fig. 4, first the lockout mechanism between sliding part 4 and front frame 1 is unlocked, make sliding part 4 can on front frame 1 slide anteroposterior; Then push away down and enclose framework 31, make after poppet 2 and second connecting rod 6 respectively relative front frame 1 overturn forward, sliding part 4 front frame 1 slide downward is relatively ordered about by first connecting rod 5 in the process of turning over before second connecting rod 6, make to enclose framework 31, second connecting rod 6, first connecting rod 5, after poppet 2 and front frame 1 little by little to draw close along the short transverse of stroller frame, closely draw close together until enclose framework 31, second connecting rod 6, first connecting rod 5, after poppet 2 and front frame 1, stroller frame is the flats compact form shown in Fig. 5, and stroller frame completes folding.In above-mentioned folding process, front-wheel 10 and trailing wheel 20 land all the time and form support to stroller frame.
when needs launch this stroller frame, then will enclose framework 31 upwards to lift, after poppet 2 and second connecting rod 6 turn over after relative front frame 1 thereupon, second connecting rod 6 pulls first connecting rod 5 and orders about sliding part 4 front frame 1 upward sliding relatively, make to enclose between framework 31, first connecting rod 5, second connecting rod 6, front frame 1 and after poppet 2 and little by little launch, until after stroller frame launches completely, lockout mechanism locks, under this stroller frame is just in stable deployed condition.
to sum up, children trolley of the present utility model, wherein by seat pocket frame 3 being set to a part for stroller frame, and participate in stroller frame folding in, so not only eliminate the parts such as push rod, decrease the rod member quantity of stroller frame, but also make this children trolley can usher to seat pocket fold, and the stroller frame volume after folding significantly reduces, and it also avoid in prior art and needs baby seat pocket to be disassembled the defect deposited separately simultaneously.In addition, the structure of this children trolley is very simple, and folding and expansion operates all very convenient, and the volume after folding is little, is easy to carry about with one and deposits.
above-described embodiment, only for technical conceive of the present utility model and feature are described, its object is to person skilled in the art can be understood content of the present utility model and implement according to this, can not limit protection domain of the present utility model 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.
