With the combination of sponge etc.；In addition, the back part is used for for baby head or back against or for for baby head
With back simultaneously against；Therefore, the material of the back part equally can be varied, and can equally use a variety of sides
Formula is fixed in the backrest bar assembly.
Incorporated by reference to reference Fig. 1 and Fig. 2, the folding children's trolley further includes handrail, one end pivot joint of the handrail
In the front end of 1 upper surface of seat part, as shown in fig. 6, when the folding children's trolley fold when, the handrail with
Articulated section is that shaft is rotated to the upper surface of seat part or rotated far from seat part, to reach keep vehicle volume side small excellent
Point.
The front-wheel support 2 further includes that pedal parts and the front component 21, the pedal parts are laterally disposed, institute
The both ends that the pedal device is arranged in front component 21 are stated, the middle position of the pedal parts and the lower end of front-wheel support are solid
Fixed connection, the preferably middle position of pedal parts, are to avoid overturning to keep folding children's trolley stability more preferable
It is dangerous.
The upper end of rear wheel support 3 and the front end of seat part 1 are pivotally connected at the first articulated section A, and can be with the first articulated section A
For rotation axis relative rotation, the drive-connecting shaft of this first articulated section A can have axial length Telescopic；Such Telescopic can
To adapt to different seat parts.
The intermediate upper position of rear wheel support 3 is at the B of third articulated section by rotation axis B1 and front-wheel support 2 in third pivot
Axis connection at place B is connect, two components can relatively rotate；Rotation axis B1 is cambered axle of the same plane with angle, and rear wheel support 2 is around the
When three articulated section B are rotated clockwise as shown in Fig. 2, under the action of the first rotation inclined-plane 23 and the second rotation inclined-plane 33 after two
Wheel assembly 31 can gradually be drawn close as shown in Figure 4 inwardly；The upper end of rear wheel support 3 is around third articulated section B also clockwise at this time
Rotation, first rotation inclined-plane 23 with second rotate inclined-plane 33 under the action of, the upper end of rear wheel support 3 hold shelves can become larger as
Shown in Fig. 4, keep folding process more smooth with axial length Telescopic so the riveting axis of the first articulated section A is done.It is described
Front component 21 and the wheel assembly 31 move toward one another, so that the front component 21 and the wheel assembly 31 be made mutually to lean on
Closely, at this point, the front component 21 and the wheel assembly 31 close up to contacting with each other or close to contacting with each other.
The third articulated section B is at the 1/6~1/2 of front-wheel support, it is preferable that the third articulated section B is in front-wheel branch
Upper position or so in frame, seat part 1, rear wheel support 3, sliding part D, are pivotally connected in the first articulated section A, third front-wheel support 2
The slide link mechanism formed under the action of place B, the second articulated section C and sliding part D, the third articulated section B is in front-wheel branch
Upper position or so makes slide link mechanism in sliding more smooth in frame.
Sliding part D can be slided, sliding part D in the intermediate upper position of front-wheel support 2 along the upper end track of front-wheel support 2
Upper end the second articulated section C and the rear end of seat part 1 riveted at the second articulated section C, and can be opposite at the second articulated section C
Rotation；There is locking device, when product normal use as shown in Fig. 2, locking device locks, sliding part D is with before on sliding part D
Wheel support 2 will not opposite sliding.When needing to fold, locking device unlock, sliding part D and front-wheel support 2 opposite can be slided, locking
Device equally can reach the effect of vehicle frame locking elsewhere；As long as in addition, the upper end of front-wheel support 2 and the sliding part
D is matched, to realize entire baby carriage locking and unlocking when folding and being fully deployed.
As shown in Fig. 2, seat part 1, front-wheel support 2, rear wheel support 3, sliding part D, in the first articulated section A, third pivot
A slide link mechanism is formed under the action of the place of connecing B, the second articulated section C and sliding part D, it is upward when applying at sliding part D
Power F1, locking mechanism unlock sliding part D on sliding part D along front-wheel support 2 upper end track upward sliding, as shown in figure 5,
It also can gradually be drawn close at this time to front-wheel support 2 with the movement of sliding part D at the first articulated section of front end A of seat part 1, first
Articulated section A is simultaneously again in the upper end of rear wheel support 3, and under the action of slide link mechanism, the first articulated section A is around third articulated section
B is rotated clockwise, and rotation axis B1 is cambered axle of the same plane with angle, and rear wheel support 2 is rotated clockwise around third articulated section B
When, rear wheel support 3 gradually draws close the work as shown in Fig. 2, on the first rotation inclined-plane 23 and the second rotation inclined-plane 33 to front-wheel support 2
It can gradually be drawn close inwardly as shown in Figure 4 with lower two wheel assemblies 31.The upper end of rear wheel support 3 is around third articulated section B at this time
Also it is rotating clockwise, under the action of the first rotation inclined-plane 23 and the second rotation inclined-plane 33, a shelves meeting is had in the upper end of rear wheel support 3
It becomes larger, keeps folding process more smooth with axial length Telescopic so the riveting axis of the first articulated section A is done.Continue
F1 is applied to sliding part D and slides into position shown in Fig. 6, rear wheel support 3 is drawn close with front-wheel support 2 at this time, and two wheel assemblies
31 also draw close as far as possible as shown in fig. 7, reaching the state of folding.
Reversed applied force F2, sliding part D reverse movement, under the action of slide link structure, sliding part D is moved to Fig. 2
Shown position, locking device can lock automatically, reach the opening state of vehicle frame；It should be noted that in embodiments herein,
Other locking devices can also be set at any pivoting point.
Push-rod assembly 4 and front-wheel support 2 are stretching structure, can also be same for fold mechanism to realize that folding volume is smaller
The requirement of folding can be met.
In embodiments herein, the folding children's trolley includes described in two front components 21 and two
Wheel assembly 31.In other embodiments, the folding children's trolley is also possible to include two 21 Hes of front component
One wheel assembly 31 or the folding children's trolley are also possible to include the front component 21 and two
Wheel assembly 31 described in item or the folding children's trolley are also possible to include more front components 21 and institute
State wheel assembly 31.It only needs to guarantee the existing front component 21, and has the wheel assembly 31, and the front component
21 and the wheel assembly 31 sum be three or more.
It should be noted that in the present embodiment, above-mentioned first articulated section A, third articulated section B, in the second articulated section C, respectively
In each articulated section between the structures such as a bar, the structures such as each bar can be made each by rivet or pin or axis connection
Articulated section can achieve corresponding rotates effe or pivot effect.
It is as above that the utility model discloses specific embodiment, but the utility model is not limited to this, any art technology
Personnel are not departing within the scope of the spirit of the present invention, and the change made belongs to the range of the utility model protection, therefore, this
The protection scope of utility model is subject to the scope of the claims.
