Shown in Fig. 3, Fig. 4, Fig. 7 A and Fig. 7 B, be the action specification of folding control group 5 of the present invention, when 5 stationary states are organized in folding control, by the projection 511 of wedge 51 in the process of pushing with fixing part 541 collisions of safety latch fitting 54, can't carry out push action, have the safety lock function; Before carrying out push action, need pull safe latch fitting 54 earlier, fixing part 541 is departed from by wedge 51 push direction and fixing part 541 is fixing, can push, capstan 52 is rotated, pliability connecting piece 53 makes folding control organize the action of 5 may command folding actuators 4 with the following drive block 41 of capstan 52 rotations and pulling folding actuator 4 on the capstan 52; Its capstan 52 protuberance 521 when rotation can collide safe latch fitting 54, makes safe latch fitting 54 releasings fixing, and is returned to fixing part 541 by the elastic component 55 of link, and projection 511 offsets with supporting admittedly in fixing part 541.

Shown in Fig. 3, Fig. 5 A, Fig. 5 B and Fig. 5 C, running explanation for above-mentioned pliability connecting piece 53

control folding actuators

4,53 pullings of pliability connecting piece are drive block 41 down, drive block 41 is slided along last drive block 42, cell body 412 of drive block 41 is in drawing process under it, washer portion 433 collisions with resilient pin 43, allow the washer portion 433 of resilient pin 43 along the whole resilient pin 43 of cell body 412 liftings, make the shank 432 of resilient pin 43 lower ends break away from expansion hole 121 or folding hole 122, handle pipe 2 is slided along front foot pipe 12 and is done the action of folding or expansion; Drive block 42 can be replied upward drive block 42 and drive block 41 correspondence positions down by the elastic component of burying underground 44 with the following piece 41 that drives on it, and resilient pin 43 can be inserted then by upper end elastic parts 431 answer shanks 432 and launch hole 121 or folding hole 122.

As Fig. 8 and shown in Figure 9, be front-wheel 6 self-orientation modes, when directed directed part 62 past directed seats 61 are pulled, the orientation button 6211 of stampeding section 621 is turned to steering base 64, go to guide slot 611 and fasten orientation automatically, need not earlier wheel 69 correctings to be remake orientation.

As Fig. 2, shown in Figure 10 and Figure 11 A, action specification for back wheels 7 synchronous brakes and releasing brake, main brake piece 72 and auxiliary brake piece 74 maintenances location status one on the other, when brake, trample the stampeding section 721 of main brake piece 72, make main brake piece 72 lower ends brake cross bar 723 down snap in the brake tooth 791 of wheel 79,74 of auxiliary brake pieces that affect via brake linkage spare 76 upwards slide simultaneously, make auxiliary brake piece 71 brake cross bars 741 snap in the brake tooth 791 of homonymy wheel 79 with it, and by the passive release portion 722 of main brake piece 72 with release the pedal 73 initiatively release portions 731 support mutually and engage maintenance braking state (shown in Figure 11 B) admittedly.And when removing braking state, when making doll carriage be in the brake release position, play and release the pedal 73, allow and initiatively discharge 731 ones and do not engage with passive release portion 722 is driven, the brake elastic component 75 that is embedded in main brake piece 72 and wheel seat 71 and auxiliary brake piece 74 and the wheel seat 71 discharges, allow the brake cross bar 723 of main brake piece 72 and the brake cross bar 741 of auxiliary brake piece 71, the brake tooth 791 of separating wheel 79 is removed braking state to reach with portion.

Shown in Fig. 3, Fig. 4 and Fig. 5 A, when baby stroller is when launching stationary state, 2 resilient pins 43 by folding driving unit 4 of handle pipe penetrate and are fixed in the open-work 21 of handle pipe 2 and in the expansion hole 121 of front foot pipe 12, reach and launch fixing function; As Fig. 8 and shown in Figure 9, when the user wants the folding baby stroller, pull orientation the button 6211 automatic and guide slot 611 fastening orientations that front-wheel 6 directed parts 62 make stampeding section 621, after front-wheel 6 orientations, shown in Figure 12 A and Figure 12 B, the handle pipe 2 of baby stroller is adjusted to plumbness, and pull the safe latch fitting 54 of folding control group 5, so that push by wedge 51, the resilient pin 43 of control folding actuator 4 breaks away from expansion hole 121 and open-work 21, make the handle pipe 2 can be along front foot pipe 12 downward foldings, the rear foot tube 13 that coupled frame 3 links is drawn close folding to front foot pipe 12, when the open-work 21 of handle pipe 2 and folding hole 122 to on time, resilient pin 43 can run through fixedly finishes the folding action, the stampeding section 621 of front-wheel 6 is collided in handle pipe 2 lower ends in the folding process, it is directed that directed button 6211 in stampeding section 621 and guide slot 611 are removed, and makes things convenient for folding and takes in; Operation folding control group 5 can be pulled to expanded position with handle pipe 2 and fix during expansion, and the rear foot tube 13 that coupled frame 3 links also outwards launches simultaneously.Above-mentioned action only needs one hand to operate, and need not both hands or pin is assisted, and greatly facilitates the user.
