[specific embodiment]
The utility model is further described with reference to the accompanying drawing:
As shown in Figures 1 to 6, a kind of perambulator skeleton can be moved to folding position from expanded position, comprising:
Foreleg 1 is connected with front-wheel 1a on the foreleg；
Back leg 2 is connected with rear-wheel 2a on the back leg；
Back support bar 3,3 lower end of back support bar and back leg 2 are rotatablely connected；
Side handrail 4, described 4 one end of side handrail and back support bar 3 are rotatablely connected, and the other end and foreleg 1 are rotatablely connected；
Seat support bar 5, described 5 one end of seat support bar and back support bar 3 are rotatablely connected, and the other end and foreleg 1 rotate
Connection；
Draw bar 6, described 6 one end of draw bar and foreleg 1 are rotatablely connected, and the other end and 2 upper end of back leg are rotatablely connected.
As shown in Figures 1 to 6, back support bar 3, side handrail 4, foreleg 1 and seat support bar 5 constitute four-bar mechanism, are pushing away
During dynamic 3 upper end of back support bar travels forward, the lower end of back support bar 3 is moved to rear side, and 3 lower end of back support bar is moved through to rear side
Cheng Zhong, the seat support bar 5 that both ends are rotatablely connected with back support bar 3 and foreleg 1 respectively just pull foreleg 1 to rotate to rear side, foreleg 1
Into rear side rotation process, foreleg 1 just pushes the draw bar 6 being rotatablely connected with it, and draw bar 6 is just pushed and is rotatablely connected with it
2 upper end of back leg, move 2 upper end of back leg to rear side, then 2 lower end of back leg just travels forward, and realizes that foreleg 1 and back leg 2 are handed over
Fork, and then realize that perambulator skeleton folds, volume after folding is small, and it is compact-sized, it occupies little space, easy to carry, folding process behaviour
Facilitate, folds flexibly.
As shown in Figures 3 to 5, the seat support bar 5 includes the support section 51 and opposite support for support seat cushion
The bending segment 52 that section 51 is folded upward at, 52 upper end of bending segment and back support bar 3 are rotatablely connected, and the support section 51 is with before
Leg 1 is rotatablely connected.Therefore, when promotion back support bar 3 forward folds perambulator skeleton, seat support bar 5 can be for greater flexibility
Foreleg 1 is pulled to rotate backward, to keep perambulator skeleton folding more flexible.
As depicted in figs. 1 and 2, the back leg 2 is located at the inside of back support bar 3, and the seat support bar 5 is located at backrest
The outside of bar 3.
As shown in Figures 2 to 5, the seat support bar 5 position that is connected with foreleg 1 forms the first tie point A, described
The position that is connected with foreleg 1 of side handrail 4 form the second tie point B, the draw bar 6 position that is connected with foreleg 1 is formed
Third tie point C, also, the first tie point A is between the second tie point B and third tie point C.Therefore, in child
Folding is more flexible when vehicle skeleton folds, more convenient operation.
As shown in Figures 2 to 5, the seat support bar 5 be connected with back support bar 3 position formed the 4th tie point D, institute
The side handrail 4 the stated position that is connected with back support bar 3 forms the 5th tie point E, and the back support bar 3 is connected position with back leg 2
The 6th tie point F is formed, also, the 4th tie point D is between the 5th tie point E and the 6th tie point F.Therefore,
When perambulator skeleton folds, folding is more flexible, more convenient operation.
As shown in Fig. 1, Fig. 8 and Fig. 9, the locking mechanism of the perambulator skeleton is arranged between back support bar 3 and back leg 2,
The locking mechanism includes being located at the hinged shell 71 in a left side of 3 lower end of back support bar and being located on back leg 2 and rotate with left hinged shell 71
The hinged shell 72 in the right side of connection, the hinged shell 71 in the left side and right hinged shell 72 surround cavity, the hinged shell 71 in a left side and right hinge
Spline 73 is respectively equipped on the inner wall of body contact 72, being equipped in the cavity can be in cavity when perambulator skeleton needs to fold
The spline 74 for laterally sliding and being detached from the spline 73 on left hinged shell 71 is set between the spline 74 and right hinged shell 72
Spline 74 can be pressed in the expansion of perambulator skeleton and make the spline on spline 74 and left hinged shell 71 and right hinged shell 72 by having
The springs 75 of 73 engagings simultaneously, are additionally provided with the drag-line 76 that can pull 74 transverse movement of spline in the back support bar 3.It is needing
When folding baby carrier skeleton, 74 transverse movement of spline is pulled by drag-line 76, the spline 73 on spline 74 and left hinged shell 71 is de-
From back support bar 3 can be rotated relative to back leg 2 at this time, and perambulator skeleton is able to unlock and fold.When perambulator skeleton is in unfolded state
When, spline 74 engages with the spline 73 on left hinged shell 71 and right hingedly shell 72 simultaneously, at this time back support bar 3 cannot relatively after
Leg 2 rotates, and perambulator skeleton is maintained for unfolded state.Certainly, the locking mechanism of perambulator skeleton can also use other structures, such as
The hook that can be rotated is set in seat support bar 5, and the pin shaft that can be engaged or be detached from hook is set in back support bar 3,
When hook catches on pin shaft, perambulator skeleton keeps expansion locking, and when hook and pin shaft disengaging, perambulator skeleton is unlocked and can be rolled over
It is folded.
As shown in Fig. 2, Fig. 3, Fig. 4 and Fig. 7, the bending segment 52 and 51 connecting position of support section are equipped in perambulator skeleton
The occlusion part 53 of left hinged shell 71, the periphery of the outer peripheral surface of the occlusion part 53 and left hinged shell 71 can be sheltered from when expansion
Face is concordant.Therefore, occlusion part 53 hides left hinged shell 71, does not observe left hinged shell 71 from perambulator skeleton side, perambulator
Skeleton seems more simplicity generosity.Moreover, in the expansion of perambulator skeleton the outer peripheral surface of occlusion part 53 and left hinged shell 71 it is outer
Circumferential surface is concordant, smooth, is not in clamp hand, and safety is good.
Seat board (not shown) can also be set in the seat support bar 5.The setting of seat board can more preferable twelve Earthly Branches
Seat cushion is supportted, baby is made to take more comfortable.
As depicted in figs. 1 and 2,3 upper end of back support bar is rotatably connected to handspike 9.
