When 1 folding of upper frame or expansion, first attachment base of back 41, which can be discharged or be locked with second attachment base 43, connects handrail
The positioning of joint chair 42 discharges handrail 4 or locks, realizes three's synchronous folding mechanism.The fixing seat 45 is connect with described first
Seat 41 is pivotally connected and can be with stroller frame in detachably connected.Specifically, as follows:
Referring to Fig. 3, the handrail attachment base 42 offers arc groove 421,421 semicircular in shape of arc groove；It is described
Second attachment base 43 is equipped with the first locating piece 431 and positioning region 432, and the positioning region 432 is located at first locating piece 431
Side beside；First locating piece 431 is in slidably to be set in the arc groove 421 relatively, first attachment base 41
Equipped with the second locating piece 411, second locating piece 411 is slidably arranged in the arc groove 421, when it is described can folding help
When hand 4 is unfolded, first locating piece 431 and the second locating piece 411 are located at the both ends of the arc groove 421, Jin Erding
The position handrail attachment base 42, when 44 folding of handrail, the relatively described arc groove 421 of second locating piece 411 is slided into
Close to first locating piece 431, and second locating piece 411 is stuck in the positioning region 432.The positioning region 432 is bullet
Reed, when 44 folding of handrail, second locating piece 411 is crossed the spring leaf and is engaged with the spring leaf.The spring
Piece has the ability to automatically reset, from the purpose for being then able to achieve automatic positioning.
Fig. 6 to Fig. 8 is please referred to, the handrail 44 is in be removably attachable on the handrail attachment base 42.Specifically,
Any one of the handrail 44 and the handrail attachment base 42 extend outward connecting column 422, handrail attachment base of the present invention
Connecting column 422 is extended in 42 outside, and the middle part of the connecting column 422 is equipped with connecting hole 422a, and the handrail 44 is recessed inwardly
Ground is equipped with matching hole 441, and the connecting column 422 is socketed in the matching hole 441.Pass through connecting column 422 and matching hole 441
Cooperation, the intensity of the handrail 44 with 42 junction of handrail attachment base can be reinforced, make handrail 44 and handrail attachment base
42 connect stronger.The reinforced sheet 442 stretched out to hole outside direction, the reinforced sheet 442 are equipped in the matching hole 441
It inserts in the connecting hole 422a.The reinforced sheet 442, which is arranged, can further strengthen the handrail 44 and handrail company
The intensity of 42 junction of joint chair guarantees handrail 44 and 42 stable connection of handrail attachment base.
Fig. 6 to Fig. 8 is please referred to again, clamping mechanism 46 is equipped in the matching hole 441, and the clamping mechanism 46 includes card
Close hook 461, button 462 and dynamic clamping head and quiet clamping head 463, the side wall of the connecting column 422 is equipped with to be engaged with the clamping hooked 461
Connecting hole 422b.The button 462 is slidingly arranged in the matching hole 441, the clamping hooked 461 be fixed on it is described by
Button 462.The handrail 44 can be made to realize with the handrail attachment base 42 using the clamping hooked 461 to be detachably connected, improve
The convenience used.The dynamic clamping head and quiet clamping head 463 is compressed spring, and the both ends of the compressed spring are flexibly resisted against described
Between button 462 and the handrail 44, it is sticked in the clamping hooked 461 automatically in the connecting hole 422b to provide one
Elastic force and stretch out the button 462 except the handrail 44.
In summary it and combines shown in Fig. 4 and Fig. 5, the folding process of baby carrying vehicle 100 of the invention is carried out below detailed
Thin description, as follows:
When folding, the upper frame 1 is pushed manually, rotates the upper frame 1 to the direction close to the lower vehicle frame 2,
At this moment, the upper frame 1 drives first attachment base 41 to rotate relative to second attachment base 43, the arc groove 421 with
The opposite sliding of first locating piece 431；At this point, the handrail attachment base 42 is released, and handrail 44 with the rotation leaned against and
Folding.When the upper frame 1 and the lower 2 complete folding of vehicle frame relatively of the handrail 44, first locating piece 431 from
One end of the arc groove 421 slides into the other end of the arc groove 421, also, will reach the arc groove 421
The other end when, second locating piece 411 is crossed the spring leaf and is engaged with the spring leaf, so that the upper frame
1 with first attachment base 41 and 42 relative positioning of handrail attachment base.When seat expansion, upper frame 1 descends vehicle frame relatively
During 2 expansion, the locating piece 411 on the first attachment base 41 can drive handrail attachment base by the end of the arc groove 421
42, so that handrail be made to reach unfolded state and be positioned with the locking of the first attachment base 41 and the second attachment base 43.
When expanded, the upper frame 1 is pulled manually, and second locating piece 411 is made to cross the spring leaf and is detached from
Engage with the spring leaf, so that the upper frame 1 be made to rotate to the direction far from the lower vehicle frame 2；At this moment, described first
When the movement and folding of attachment base 41, the handrail attachment base 42 and the second attachment base 43 on the contrary, to be can be directly by institute
It states upper frame 1 and the handrail 44 is unfolded.
When needing the handrail 44 separating the handrail attachment base 42, it is only necessary to button 462 described in Manual press,
The button 462 compresses the compressed spring and the clamping hooked 461 is driven to move in the handrail 44, so that the card
It closes hook 461 and is detached from connecting hole 422b；At this point, the handrail 44 is unlocked with the handrail attachment base 42, it can be by the handrail 44
It removes.
When needing the handrail 44 being installed to the handrail attachment base 42, it is only necessary to be inserted into this reinforced sheet 442
It into the connecting hole 422a, then is placed on the connecting column 422 in the matching hole 441, and makes the clamping hooked 461
It is corresponding with the connecting hole 422b, at this moment, the compressed spring elastic force effect under, 461 automatic fastening of clamping hooked in
In the connecting hole 422b, and then the handrail 44 and the handrail attachment base 42 are locked, the two can be connected together.
Compared with prior art, the present invention is by being fixedly connected on the upper of baby carrying vehicle 100 for first attachment base 41
Vehicle frame 1, and the handrail 44 is connected on the handrail attachment base 42, connect the handrail attachment base 42 with described first
Joint chair 41 is pivotally connected, then by the way that second attachment base 43 to be articulated on the handrail attachment base 42, so that the handrail
44 can lean against synchronous folding mechanism with described, and can opposite baby carrying vehicle 100 2 folding of lower vehicle frame, it is easy to operate, effectively reduce
Occupied space improves the convenience of carrying；In addition, by offering arc groove 421 in the handrail attachment base 42, described
First attachment base 41 is equipped with the second locating piece 411, and is equipped in second attachment base 43 and is slidingly arranged at the arc groove
The first locating piece 431 on 421 and the positioning region 432 to second locating piece 411 positioning, so that baby carrying vehicle
100 lean against and handrail 44 can position upon deployment, make to lean against and the expansion of handrail 44 or folding it is more convenient.
Under the premise of not influencing foldable handrail 4 and operating, upper frame 1 can be driver tube in baby carrying vehicle 100 or
Pipe is leaned against, and lower vehicle frame 2 can be seat tube, front foot pipe or foot tube in baby carrying vehicle 100.
The above disclosure is only a preferred example of the present invention, cannot limit the right of the present invention with this certainly
Range, therefore according to equivalent variations made by scope of the present invention patent, still fall within the range that the present invention is covered.
