Specific implementation mode
Technical solution to further illustrate the present invention below with reference to the accompanying drawings and specific embodiments.
The present invention provides a kind of foldable baby cart, and as depicted in figs. 1 and 2, which includes
Push-rod assembly 1, chassis tube assembly 3, sliding block 4, connecting rod 5, strut 6, is arranged in 3 preceding lower end of chassis tube assembly fore-stock component 2
Front component 7 and wheel assembly 8 in 3 posterior end of chassis tube assembly is set, wherein：
1 lower end of push-rod assembly rotates pin joint with 2 upper end of fore-stock component, specifically, in the present embodiment, above-mentioned push-rod assembly
1 includes lower push-rod component 1-1, upper push-rod component 1-2 and push handle component 1-3, lower push-rod component 1-1 and upper push-rod component 1-2
Pin joint is rotated, and is equipped with second locking mechanism (not shown) between the two, is used for lower push-rod component 1-1 and upper push-rod group
Part 1-2 is locked or unlocked.Above-mentioned second locking mechanism be it is relatively conventional between two relatively turnable components into
Locking structure of row locking and unlock, such as bayonet lock locking, trip bolt locking etc., type is also more, in the present embodiment
No longer its structure is limited, as long as disclosure satisfy that the locking between lower push-rod component 1-1 and upper push-rod component 1-2 and solution
Lock.
Above-mentioned push handle component 1-3 is slidably connected with upper push-rod component 1-2, is pushed away under specifically upper push-rod component 1-2 is not connected
One end of bar assembly 1-1 is set in outside one end of push handle component 1-3, and above-mentioned push handle component 1-3 can relative to upper push-rod component 1-2
Sliding, when stroller is unfolded, push handle component 1-3 is stretched out relative to upper push-rod component 1-2.Push handle component 1-3 with above push away
Third locking mechanism is equipped between bar assembly 1-2, for push handle component 1-3 and upper push-rod component 1-2 to be locked and unlocked.
Likewise, above-mentioned third locking mechanism is also the common locking structure of this field, therefore no longer its structure is illustrated, is only needed
It disclosure satisfy that the locking and unlock between push handle component 1-3 and upper push-rod component 1-2.
In the present embodiment, the lower end of above-mentioned lower push-rod component 1-1 and fore-stock component 2 rotate pin joint, in-between position with
The rear end thereof pin joint of connecting rod 5.
Fig. 2 is can refer to, above-mentioned sliding block 4 is slidably connected on fore-stock component 2, middle part and 4 pin-connect of sliding block of strut 6,
The upper and lower ends of strut 6 distinguish pin joint on the front end of connecting rod 5 and chassis tube assembly 3,2 lower end of fore-stock component and chassis pipe
3 front end of component rotates pin joint.
The present embodiment by the pin joint state between above-mentioned all parts, can realize entire stroller expansion and
It folds.
Specifically, being equipped with first locking mechanism (not shown) between sliding block 4 and fore-stock component 2, pushed away in baby
When vehicle is in unfolded state, which locks stroller, to ensure that stroller being capable of normal use.In push rod
Component 1 is equipped with unlocking mechanism (not shown), for releasing locking of the first locking mechanism to stroller, so as to follow-up
Folding operation.By above-mentioned first locking mechanism and unlocking mechanism, the locking to stroller vehicle and solution can be realized
Lock is locking structure and unlocking structure commonly used in the art, therefore no longer repeats its structure.It needs to illustrate
Be, as long as disclosure satisfy that the structure to the vehicle of stroller locking and unlock, all can be the present embodiment the first locking machine
Structure and unlocking mechanism.
Can refer to Fig. 2, above-mentioned chassis tube assembly 3 include preceding chassis pipe 3-1 and rear chassis pipe 3-2, preceding chassis pipe 3-1 and
Pin joint is rotated between chassis pipe 3-2 afterwards and is equipped with the 4th locking mechanism (not shown), the lower end of strut 6 and preceding chassis pipe 3-
1 pin-connect.By the pin joint between preceding chassis pipe 3-1 and rear chassis pipe 3-2, the folding to chassis tube assembly 3 can be realized, and
And also allow for the manufacture of chassis tube assembly 3.Above-mentioned 4th locking mechanism for realizing preceding chassis pipe 3-1 and rear chassis pipe 3-2 it
Between locking and unlock, be locking structure commonly used in the art, therefore no longer its structure repeated.
In the present embodiment, 6 U-shaped structure of above-mentioned strut, before both sides are respectively hinged on chassis pipe 3-1, for real
Now to the installation of the support of stroller and stroller seat pocket.
The foldable baby cart of the present embodiment first passes through the locking solution that unlocking mechanism pushes away entire baby when folding
It removes, the locking between push handle component 1-3 and upper push-rod component 1-2 is then released by third locking mechanism, then by handle group
In part 1-3 push-in upper push-rod components 1-2, i.e., shown in Fig. 3.
Later, by second locking mechanism by the latch-release between upper push-rod component 1-2 and lower push-rod component 1-1,
Fold upper push-rod component 1-2 is to lower push-rod component 1-1 is close to backward, as shown in Figure 4.
After having turned down upper push-rod component 1-2, lower push-rod component 1-1 is turned down forward, and upper push-rod component 1-2 is pushed away under at this time
Bar assembly 1-1 is turned down forward together, during fold, due to lower push-rod component 1-1, sliding block 4, connecting rod 5, strut 6, preceding branch
Pin joint structure between frame component 2 and chassis tube assembly 3, lower push-rod component 1-1 can drive connecting rod 5 first to push strut 6 forward
Preceding chassis pipe 3-1 is conformed to, then the sliding effect due to sliding block 4 on fore-stock component 2 and the pin joint with strut 6, energy
Enough so that connecting rod 5 is pushed down bar assembly 1-1 and pushes fitting chassis tube assembly 3 backward, and final lower push-rod component 1-1 is conformed to
Fore-stock component 2, as shown in figs.5 and 6.
Finally, the locking between preceding chassis pipe 3-1 and rear chassis pipe 3-2 is released by the 4th locking mechanism, and will after
Chassis pipe 3-1 is folded chassis pipe 3-2 forward, is finally completed the folding of entire stroller, as shown in Figure 7.
When carrying out the expansion of stroller, the above-mentioned stroller folding process of reverse operating is only needed, and be unfolded in vehicle
When vehicle is locked by first locking mechanism.
Obviously, the above embodiment of the present invention is just for the sake of clearly illustrating examples made by the present invention, and it is pair to be not
The restriction of embodiments of the present invention.For those of ordinary skill in the art, may be used also on the basis of the above description
To make other variations or changes in different ways.There is no necessity and possibility to exhaust all the enbodiments.It is all this
All any modification, equivalent and improvement etc., should be included in the claims in the present invention made by within the spirit and principle of invention
Protection domain within.
