[specific embodiment]
The invention will be further described below in conjunction with the accompanying drawings:
As shown in Figures 1 to 8, a kind of baby stroller skeleton can be moved to after locking device unlock from expanded position
Folding position, comprising:
Foreleg 1,1 lower end of foreleg are connected with front-wheel 1a;
Back leg 2,2 lower end of back leg is connected with rear-wheel 2a, and 2 upper end of back leg and foreleg 1 turn around axis B
Dynamic connection;
Front strut 3, the lower end of the front strut 3 and the upper end of foreleg 1 are rotatablely connected around axis C;
Interlocking lever 4,4 lower end of interlocking lever and back leg 2 are rotatablely connected around axis D, and 4 upper end of interlocking lever is with before
Strut 3 is rotatablely connected around axis E, and the interlocking lever 4, front strut 3, foreleg 1 and back leg 2 constitute four-bar mechanism;
Seat frame 5, described 5 one end of seat frame and back leg 2 are rotatablely connected around axis F, 5 other end of seat frame around
Axis G is rotatably connected to the sliding part 7 that the opposite foreleg 1 of energy slides.
As shown in Fig. 5 to Fig. 8, when baby stroller skeleton folds, 3 upper end of front strut is close to 2 lower end of back leg, foreleg
1 lower end is close to 2 lower end of back leg, and in the process, back leg 2 pushes seat frame 5 to rotate, and the front end of seat frame 5 is just with sliding part 7
Together along 1 glide downwards of foreleg, to realize the folding of entire baby stroller skeleton.Easy to operate, volume after folding is small, just
In carrying.
As shown in Figure 3 and Figure 5, the seat frame 5 includes attachment base 51,51 front end of attachment base and sliding part 7
It is rotatablely connected around axis G, 51 rear end of attachment base and back leg 2 are rotatablely connected around axis F, are also set on the attachment base 51
The seat post 52 for thering is front-rear direction to extend.Seat post 52 is made to length a little can directly take for infant, certainly, work as seat
When position bar 52 is made shorter, the interconnecting piece for installing seat can be set in 42 rear end of seat post, such infant is not just straight
It connects and is sitting in seat post 52, but be sitting in dismountable seat, dismantle seat cushion convenient for user and clean.
The baby stroller skeleton further includes preceding handrail 8, and the preceding handrail 8 includes and 1 upper end of foreleg or preceding support
The rotation seat 81 of 3 lower end of bar rotation connection, in the present embodiment, the rotation seat 81, foreleg 1 and front strut 3 are same around axis C
Axis rotation connection.There can be handrail 82 on the rotation seat 81 with dismantling connection, be set between the rotation seat 81 and back leg 2
There is draw bar 9 hinged with the two and that the rotation of rotation seat 81 can be drawn when baby stroller skeleton folds.In the present embodiment,
Draw bar 9, back leg 2 and the attachment base 51 rotates coaxially connection around axis F, and the draw bar 9 and rotation seat 81 are around axis
Line H rotation connection.Preceding handrail 8 is grasped for infant, it is ensured that safety.When baby stroller skeleton folds, the traction of draw bar 9 turns
Dynamic seat 81 rotates, and rotation seat 81 just drives handrail 82 to rotate in rotation, in folding of baby state, such as Fig. 8, and handrail
Bar 82 turns to Danone and tows for user or portable position, carries the perambulator folded convenient for user.
As shown in Fig. 4, Fig. 6 and Fig. 7, the draw bar 9 is curved curved rod, and the draw bar 9 is from top to bottom
Through back leg 2 and opposite 2 activity of back leg of energy.Therefore, the structure of entire perambulator will be very compact, and be folded together also very spirit
It is living.
As shown in Figure 1, Figure 2, shown in Fig. 9 and Figure 10, the front strut 3 is equipped with the opposite handspike 10 that it is slided of energy, institute
Slide bar 11 is connected on the handspike 10 stated, the front strut 3 is equipped with can be for slide bar when handspike 10 is slided with respect to it
11 sliding slots 12 slided inside, 11 lower end of slide bar, which is equipped with, can follow the top seat slided when it is slided in sliding slot 12
13, the top seat 13 is equipped with top bracket 14.Moreover, support can make baby on the ground jointly for rear-wheel 2a and handspike 10
Youngster's handcart frame keeps standing in folded state, and the baby stroller of folded state is parked convenient for user.In folding of baby
When, it pushes down on handspike 10 and passes through the slide bar being connected on handspike 10 when handspike 10 is with respect to 3 glide downwards of front strut
11 push 13 glide downwards of top seat, top bracket 14 are rotated after top seat 13 slides in place, so that in folding baby
The linkage that top bracket 14 is realized when trolley, operates more simple and fast.Moreover, in baby stroller folded state, it is described
Handspike 10 and rear-wheel 2a support on the ground and make baby stroller keep stand, the baby of folded state is parked convenient for user
Youngster's trolley.
As shown in figures 1 and 3, the sliding part 7 is sliding block, and the foreleg 1, which is equipped with, to be slided inside for sliding block
Sliding slot 15.Sliding block slides in sliding slot 15, and operation is very steady, so that baby stroller folds flexibly.Certainly, the cunning
Moving part 7 or the sliding sleeve being set on foreleg 1, slide over when baby stroller folds and slide on foreleg 1, fold spirit
It is living.
