In the present embodiment, on the side stand 100 per side, back link 5 is pivotally connected in after-poppet 2 by the 6th axis 16 On, the forepart of back link 5 is connect with the rear portion of front rod 4 by 17 phase pivot of the 7th axis;The forepart of front rod 4 passes through the 8th axis 18 are pivotally connected on fore-stock 1, and the 8th axis 18 is located at the lower section of first axle 11 on fore-stock 1;The top of upper connecting rod 6 leads to It crosses the 9th axis 19 to be pivotally connected on push rod 3, the 9th axis 19 is located at the top of the second axis 12 on push rod 3.
In this way, referring to shown in attached drawing 3, on the side stand 100 per side, fore-stock 1, after-poppet 2, front rod 4 and back link 5 Between form four-bar mechanism, form slider-crank mechanism between seat bar assembly 7, back link 5 and after-poppet 2.Work as stroller frame It is locked under unfolded state, fore-stock 1, connecting rod 22, push rod 3 extend approximately along same length direction, front rod 4, back link 5 And a big stable triangle structure is formed between upper connecting rod 6 and fore-stock 1, connecting rod 22 and push rod 3;Seat bar assembly 7 with A small triangle knot is respectively formed between push rod 3 and upper connecting rod 6 and between seat bar assembly 7 and back link 5 and after-poppet 2 Structure, the side stand 100 after expansion are presented a highly stable structure, have good bearing stability.When stroller frame folds When, when push rod 3 is turned over so that the lower part downlink of upper connecting rod 6 and back seat bar 72 is driven to be slided backward with respect to front stall bar 71, together When bar assembly 7 is rotated relative to after-poppet 2, so as to drive each bar in above-mentioned slider-crank mechanism and four-bar mechanism Part relative motion and cause side stand 100 in each rod piece gradually collapse together, realize side stand 100 folding.
It can be set to folding in left-right direction referring to the stull component shown in each attached drawing, being connected between both sides side stand 100 It puts between the side stand 100 of both sides.The stull component includes the front strut component 8 with folding can respectively be unfolded in left-right direction And/or back brace bar assembly 9, wherein, front strut component 8 be arranged on the fore-stock 1 of both sides and the front stall bar 71 of both sides forepart it Between, back brace bar assembly 9 is arranged between the after-poppet 2 of both sides and the forepart of both sides back link 5.
Specifically, join shown in Fig. 1, Fig. 2, front strut component 8 is preceding cross support component, which includes middle part Two front struts 81 of phase pivot connection, before the one end of the front strut 81 is rotationally connected to side by the first connector 82 The lower part of stent 1, the other end are rotationally connected to the forepart of opposite side front stall bar 71 by the second connector 83, herein, First connector 82 is arranged at the 8th axis 18, and the second connector 83 is located at the 5th axis on the length extending direction of front stall bar 71 15 front.
It is rear cross support component that back brace bar assembly 9 uses herein, which connects including middle part phase pivot Two rear poles 91, the one end of every rear pole 91 is rotationally connected to side back link 5 by third connector 92 Forepart, the other end are rotationally connected to the lower part of opposite side after-poppet 2 by the 4th connector 93, herein, third connection Part 92 is located at the front of the 7th axis 17 on the length extending direction of back link 5, and the 4th connector 93 is located at the on after-poppet 2 The lower section of six axis 16.
Referring to shown in each attached drawing, on the side stand 100 of each side, the lower part of fore-stock 1 is equipped with one group of front component 20, after The lower part of stent 2 is equipped with one group of wheel assembly 30, when stroller frame is in unfolded state, between two groups of front components 20 Between left and right away from more than between both sides wheel assembly 30 between left and right away from.Setting enables to front component 20 in stroller frame in this way It is turned to during implementation more flexibly, it is laborsaving to carry out operation enhanced convenience.When stroller frame folds, fore-stock 1 with After-poppet 2 is drawn close along the longitudinal direction, and two groups of wheel assemblies 30 are collapsed in left-right direction between two groups of front components 20.
In this way, when stroller frame is unfolded, as shown in Figure 1 to Figure 3, the side stand 100 of both sides is unfolded respectively, front strut group Part 8 and back brace bar assembly 9 are unfolded and are transversely supported between the side stand 100 of both sides to provide cart in left-right direction respectively Vehicle frame is with the support of left and right directions.
When needing folding stroller frame, as shown in Figures 4 to 6, it is made when pushing push rod 3 with respect to after-poppet 2 backward Overturning so that 6 downlink of upper connecting rod simultaneously drives back seat bar 72 to be slid rearwardly out with respect to front stall bar 71, front stall bar 71 around the 5th axis 15 backward Overturning so that back link 5 is turned over around 16 opposite after-poppet 2 of the 6th axis, and the rear portion of front rod 4 correspondingly moves upwards and band Dynamic fore-stock 1 gradually collapses along the longitudinal direction with after-poppet 2 so that fore-stock 1 is collapsed with push rod 3 before after-poppet 2 respectively Both sides afterwards.During each rod piece on the side stand 100 of above-mentioned both sides relatively rotates folding, front strut component 8 two before Strut 81 relatively rotates folding, and two rear poles 91 of back brace bar assembly 9 relatively rotate folding, so that the side stand of both sides 100 gradually collapse in left-right direction.
Finally, each rod piece of each side side stand 100 rotates gathering respectively, and the side stand 100 of both sides is received in left-right direction Hold together, two wheel assemblies 30 are collapsed between two front components 20, form structure as shown in Figure 7 to 9, the cart vehicle after folding Frame structure is very smooth, compact, can also stand on ground certainly, reduces occupied space, and convenience in transport carries.
The above embodiments merely illustrate the technical concept and features of the present invention, and its object is to allow person skilled in the art Scholar can understand present disclosure and implement according to this, and it is not intended to limit the scope of the present invention.It is all according to the present invention The equivalent change or modification that Spirit Essence is made, should be covered by the protection scope of the present invention.
