Specific embodiment
Technical solution of the present invention is further elaborated in the following with reference to the drawings and specific embodiments.
Embodiment 1
Referring to Fig. 1 to stroller shown in fig. 6 comprising stroller frame with unfolded state and folded state, set on pushing away
The wheel assembly of vehicle carriage bottom, and for the locking mechanism by stroller frame locking in the deployed state.The stroller frame packet
Two side stands 100 for being divided into the left and right sides are included, the side stand 100 of every side includes the preceding branch respectively vertically extended
Bar 1, back stay 2 and push rod 3, wheel assembly include the rear-wheel set on the front-wheel 10 of 1 lower part of front support rod and set on 2 lower part of back stay
20。
Shown in Figure 2, the top of back stay 2 is rotationally connected on front support rod 1 by first axle 11, front support rod 1
The lower part of top and push rod 3 is rotatablely connected by the second axis 12, first axle 11 and the second axis 12 be parallel to each other for axial line two
Root axis, and first axle 11 is connected to the top of the second axis 12 on front support rod 1.It in other examples, can also be by first
Axis 11 is set as axial line with the second axis 12 and collinearly extends.
The side stand 100 of every side further includes the connection component being set between front support rod 1 and back stay 2, and can be upper and lower
Slidably it is set to the sliding part 4 on front support rod 1, the upper connecting rod 5 between push rod 3 and sliding part 4, wherein sliding part 4 uses
It is the sliding sleeve being slidably set on front support rod 1, one end of upper connecting rod 5 is pivotally connected on sliding sleeve 4 by third axis 13, on
The other end of connecting rod 5 is pivotally connected on push rod 3 by the 5th axis 15.
Connection component is mainly used for opposite expansion and folding between front support rod 1 and back stay 2, when stroller frame is in exhibition
Under open state, connection component is supported between front support rod 1 and back stay 2 and front-wheel 10 is opened along the longitudinal direction with rear-wheel 20
And it is supported in ground, when stroller frame folds, before being made by connection component drive front support rod 1 and the relative rotation of back stay 2
Wheel 10 is drawn close along the longitudinal direction with rear-wheel 20.Referring to shown in Fig. 1 to Fig. 3, in the present embodiment, which includes along front and back
To the lower link 6 of extension, the front of the lower link 6 is pivotally connected on sliding sleeve 4 by the 4th axis 14, and the rear portion of lower link 6 is logical
The 6th axis 16 is crossed to be pivotally connected on back stay 2.Herein, the 4th axis 14 and third axis 13 are two that axial line is parallel to each other
Axis, and third axis 13 is located at the top of the 4th axis 14 on sliding sleeve 4.
In this way, constituting crank block between front support rod 1, back stay 2, lower link 6 and sliding sleeve 4 on the side stand 100 of every side
Mechanism constitutes another slider-crank mechanism between front support rod 1, push rod 3, upper connecting rod 5 and sliding sleeve 4.Locking mechanism includes before being set to
Locking joint 8 between strut 1 and push rod 3 for locking the two, when which locks, in the side stand 100 of each side
The opposite locking of front support rod 1, back stay 2 and push rod 3.
Referring to FIG. 1 to FIG. 4, when stroller frame is in unfolded state, front support rod 1 and rear branch in each side side stand 100
Bar 2 is opposite to be unfolded and is supported in ground by front-wheel 10 and rear-wheel 20, is formed between front support rod 1, back stay 2 and lower link 6 steady
Fixed triangular structure, push rod 3 just push away operating position with what updip from front to back as shown in Figure 2 extended, and such as Fig. 3 institute
The counter of the extension of updip from back to front shown pushes away operating position, and locking joint 8 locks and each side side stand is made to be locked in expansion shape
Under state, and push rod 3 is locked to and above-mentioned just push away operating position or counter pushes away operating position.
Referring to shown in Fig. 1, Fig. 2, when push rod 3, which is in, just pushes away operating position, front support rod 1 is with upper connecting rod 5 substantially along same
Length direction extends；When push rod 3 be in it is counter push away operating position when, the overturning of upper connecting rod 5 and is supported to the front positioned at the second axis 12
Between sliding sleeve 4 and push rod 3.Stroller frame is under unfolded state, and user needs to be converted to push rod 3 by just pushing away operating position
It is counter to push away when being converted between operating position, it is only necessary to locking joint 8 first be unlocked, then overturn push rod 3 forward, on push rod 3 drives
For connecting rod 5 to correspondingly preceding overturning, sliding sleeve 4 is then correspondingly upper and lower by a small margin along front support rod 1 during push rod 3 is overturn forward
Sliding locks joint 8 and relocks, just stroller frame is locked so that push rod 3 and upper connecting rod 5 are successfully overturn to front side
It is fixed, and push rod 3 is locked to and counter pushes away operating position.Vice versa.
Referring to shown in each attached drawing, each side side stand 100 further includes handle 7, and the lower pivot of the handle 7 is connected to push rod 3
Top, between push rod 3 and handle 7 be equipped with handle locking piece 9, when handle locking piece 9 unlock and handle 7 with respect to push rod 3 overturn
When linkage of unlocking lock joint 8.In the present embodiment, two sides handle 7 is wholely set and in downward opening U-shaped, stroller frame
It further include the front rail 101 between 1 lower part of two sides front support rod and the rear transverse rod 201 between 2 lower part of two sides back stay,
The upper connecting rod 5 and lower link 6 of two sides are in left-right direction between the front support rod 1 of two sides, back stay 2 and push rod 3.
It is shown in Figure 4 when needing to fold stroller frame, first handle locking piece 9 is unlocked, and handle 7 is opposite
Push rod 3 overturns and collapses in the rear side of push rod 3；The folding of handle 7 to lock joint 8 by linkage of unlocking, at this point, referring to Fig. 5
It is shown, it drives push rod 3 to overturn forward, upper connecting rod 5 can be made to overturn therewith and drive sliding sleeve 4 along 1 slide downward of front support rod, thus
Front support rod 1 is driven to relatively rotate with back stay 2 and gradually collapse along the longitudinal direction under the action of lower link 6, until folding is complete
At, form structure as shown in Figure 6, under the folded state, vehicle frame be supported in ground jointly by the top of front-wheel 10 and push rod 3 and
It is formed and is supported oneself.
Embodiment 2
Referring to shown in Fig. 7, Fig. 8, the present embodiment and the difference of embodiment 1 are essentially consisted in, in the present embodiment, third axis 13 and
The front of the coaxial setting of four axis 14, the i.e. lower part of upper connecting rod 5 and lower link 6 is rotationally connected to sliding sleeve around same rotary centerline
On 4.In the stroller frame, push rod 3, which also has, just to be pushed away operating position and counter pushes away operating position, transfer principle and 1 phase of embodiment
Together, the folding principle of stroller frame is also same as Example 1, and details are not described herein again.
To sum up, stroller of the invention, rod piece quantity is few, and structure is simple, efficiently solves commutation cart structure
The complicated and higher problem of production cost；Meanwhile on the stroller, the expansion of the switching operation and stroller frame of push rod 3 with
Folding operation is all very convenient, and the volume of stroller frame is also very compact after folding, facilitates the routine use of user.
The above embodiments merely illustrate the technical concept and features of the present invention, and its object is to allow person skilled in the art
Scholar cans understand the content of the present invention and implement it accordingly, and it is not intended to limit the scope of the present invention.It is all according to the present invention
Equivalent change or modification made by Spirit Essence, should be covered by the protection scope of the present invention.
