Description
Technical field
The present invention relates to mechanical field, particularly relate to the body frame structure for automotive of a kind of Pushchair.
Background technology
Stroller, as a kind of portable dam for carrying infant, solves when people go out with baby
Troublesome problem, significantly reduces and carries baby children's burden when people go out.Stroller, owing to having relatively large volume, need not
Bigger space can be taken during use.In order to solve this problem, corresponding retracting mechanism is set on the stroller, makes stroller energy
Enough fold, thus reduce volume, be convenient for carrying and transport.
The main joint of current Pushchair is folding center in the middle part of car body, owing to the design of its structure often causes one
Series of problems.Referring to Fig. 1, described figure is the main joint structural blast figure of stroller in a kind of prior art.
Described main joint includes: install lid 51a, the first rotating disk 52a, the second rotating disk 53a and central gear 54a, Qi Zhong
It is equipped with, inside one rotating disk 52a and the second rotating disk 53a, the internal tooth mated with central gear.First rotating disk 52a and the second rotating disk 53a
Central gear 54a is fastened, compresses a spring between the second rotating disk 53a and central gear 54a, provide central gear by spring
The pretightning force of 54a.Lid 51a is installed there are two slotting pawls, it is possible to inject the second rotating disk 53a and central gear 54a, thus limit the
One rotating disk 52a and the second rotating disk 53a relatively rotates.Other first rotating disk 52a and the second rotating disk 53a has for cable wire trip a embedding
The draw-in groove entered.During unblock, on the one hand by tractive, lid 51a is installed, makes to insert pawl and depart from the second rotating disk 53a and central gear 54a, separately
On the one hand cable wire trip a is departed from draw-in groove by tractive.
But, mate with central gear owing to being equipped with inside the first rotating disk 52a and the second rotating disk 53a in described main joint
Internal tooth cause part be not easy processing, it addition, central gear 54a drive first rotating disk 52a rotate time easy wearing part.The
Three aspects installation lid 51a are directly by tractive, so that inserting pawl often depart from the structure of the second rotating disk 53a and central gear 54a
Unblock is made to be obstructed.

Connecing, the lower end of side stand 9 and rear wheel support 11 rotate pin joint.
In the present invention, the body frame structure for automotive of a kind of Pushchair farther includes:
Body frame structure for automotive also includes back bracket 16；
Back bracket 16 includes the first column the 161, second column 162 and the folding stand 163 being symmetrical set；
The end of first column the 161, second column 162 respectively with the first rear wheel support 1101 and the second rear wheel support 1102
Slide hinged；
Being connected between the first column 161 and the second column 162 of folding stand 163.
In prior art, when car body folds around main joint 5, the cushion 20 being arranged between push rod 6 and back bracket 16
Be stretched, and affect car load fold effect.In the present invention, column end is slide hinged with rear wheel support respectively；Work as column
When folding, stud edge rotates limit and slides on rear wheel support, thus solves that cushion is stretched and the car load that causes folds effect
Really.
Concrete, the first rear wheel support 1101 and the second rear wheel support 1102 are equipped with chute 17；First column 161 He
The end of the second column 162 sheathed sliding seat 18 respectively；Sliding seat 18 is for sliding in this chute.
It should be noted that the fit system that this slide hinged mode is not limited in above-described embodiment, such as, can make
The run-on point of column is slidably socketed on rear wheel support, so that column slides on rear wheel support；Or chute can be arranged
For engraved structure, and sliding seat can pass this engraved structure, and slides in this engraved structure.
In the present invention, the body frame structure for automotive of a kind of Pushchair farther includes:
Lock-in component includes: button 81, latch the 82, first cradle head 83, the second cradle head 84, latch back-moving spring
85 and connecting shaft 87；
First cradle head 83 and the second cradle head 84 are mutually hinged by connecting shaft 87；
In the chute that the cavity that latch 82 is accommodated between the first cradle head 83 and the second cradle head 84 is constituted, and energy
Enough slide up and down along chute；
This latch back-moving spring 85 is pressed between inner surface and the latch 82 of the first cradle head 83；
First cable wire 14 removably connects with the second cradle head 84；
Second cable wire 15 intersects with the first cable wire 14 and removably connects with the first cradle head 83.
First cradle head 83 and the second cradle head 84 are respectively provided with connecting portion and buckling parts, are provided with cable wire peace in buckling parts
Tankage；
One end of first cable wire 14 and the second cable wire 15 is respectively provided with installation hammer；
Hammer is installed embed in mounting groove.
In the present embodiment, when pushing button after 81, button 81 promotes latch 82 to move down along chute, thus unlocks first
Cradle head 83 and the second cradle head 84, enable doubling.When the first cradle head 83 and the second cradle head 84 doubling
Time, the first cable wire 14 and the second cable wire 15 are unlocked the second lock of main joint by tractive, the trip triggering the other end.
The present invention is different from prior art and is characterised by, the lock-in component in the present invention removes rotating shaft and cable wire is fixed
Part, the substitute is and use the latch of compact conformation as unlock piece.On the one hand for two cable wires are arranged on the present invention's
Hands is providing space in foldable structure.On the other hand, cable wire is connected on the cradle head of heteropleural by interleaved mode,
Avoid two cable wires are separately mounted to cable wire fixture both sides by prior art, cause because cable wire fixture rotates
Article two, cable wire action length differs, and the problem those skilled in the art that cannot open side main joint can be clearly
Solution arrives, for convenience and simplicity of description, the specific works process of the device of foregoing description, it is referred in preceding method embodiment
Corresponding process, do not repeat them here.In several embodiments provided herein, it should be understood that disclosed device
Can realize by another way.
It should be noted that the buckling parts of the first cursor 52 and the second cursor 53 has draw-in groove；First cable wire 14 He
The other end of the second cable wire 15 is respectively provided with cable wire trip；Cable wire trip embeds draw-in groove.
When the first cursor 52 and the second cursor 53 are folded to 180 °, the card that the first cursor 52 buckling parts is offered
The draw-in groove offered on groove and the second cursor 53 buckling parts is aligned with each other.Cable wire trip rotates through the first cursor 52 and second
The draw-in groove offered on the buckling parts of arm 53, thus the first cursor 52 and the second cursor 53 cannot fold, and are in lock-out state.
After cable wire trip is departed from draw-in groove by tractive, the first cursor 52 and the second cursor 53 recover folder function.
It should be noted that the epitheca of cable wire trip is connected in the pipe of the second cursor 53 by rivet, work as cable traction
During the core body of cable wire trip, core body departs from draw-in groove and is fully retracted in epitheca.
In the present invention, the body frame structure for automotive of a kind of Pushchair farther includes:
The connecting rod folded along push rod 6 direction bend in one direction it is provided with between first front-wheel support 41 and the second front-wheel support 42
3；
One end of connecting rod 3 and the first front-wheel support 41 rotate pin joint, the other end and the second front-wheel support 42 and rotate pin joint.
Connecting rod 3 includes connecting rod the first split 31 and connecting rod the second split 32；
