Description
Technical field
It the utility model is related to perambulator field, more particularly to a kind of stroller frame.
Background technology
Perambulator carries the indispensable instrument of baby's trip as family, has and the function such as takes, dosses for baby.Perambulator
Vehicle frame is the conduct chief component of perambulator, and baby carriage frame structure determines perambulator major part function.It is but existing
Stroller frame foldable structure is complex, it is necessary to carry out multi-step folding, and folding efficiency is relatively low；Especially existing perambulator car
Interaction relation design of the frame between arm-rest frame and frame body is unreasonable, therefore further improvement need to be made to it.
The content of the invention
In order to solve the above problems, the purpose of this utility model is to provide a kind of stroller frame, the stroller frame
Arm-rest frame and frame body between can carry out linkage folding, folding efficiency is high.
In order to realize above-mentioned purpose, the utility model employs following technical scheme：
A kind of stroller frame, including main body of vehicle frame, and the arm-rest frame being arranged on main body of vehicle frame；
The main body of vehicle frame includes front-wheel support and rear wheel support, and arm-rest frame includes lower tube body and upper tube body；The upper tube
The bottom of body and the upper end of lower tube body are hinged；The upper end of front-wheel support, the upper end of rear wheel support and lower tube body
Bottom is hinged by threeway part；
It is connected between the front-wheel support and rear wheel support by the first joining beam, the both ends of the first joining beam are respectively articulated with
On front-wheel support and rear wheel support；It is connected between rear wheel support and lower tube body by the second joining beam, the both ends of the second joining beam
Portion is respectively hinged on rear wheel support and lower tube body；The bottom of the rear wheel support and upper tube body is connected by joining beam component,
Joining beam component includes the 3rd joining beam that upper end is hinged on upper tube body, and bottom is hinged on the tetrad on rear wheel support
Bar, the bottom and the upper end of four-bar linkage of the 3rd joining beam are hinged.
Preferably, front component is located on the bottom of the front-wheel support, positioned on the bottom of rear wheel support
There is wheel assembly.
Preferably, first joining beam and pin joint of second joining beam on rear wheel support are overlapping.
Preferably, being socketed with connection sheet on the bottom of the upper tube body, the upper end of the 3rd joining beam is hinged on connection
On piece.
The utility model uses above-mentioned technical proposal, and the technical scheme is related to a kind of stroller frame, the stroller frame
In arm-rest frame and frame body between can carry out linkage folding, folding efficiency is high.Specifically, the stroller frame folds
When, first arm-rest frame is unlocked（Prior art）, then to turnover upper tube body in front of vehicle frame, can be applied while upper tube body is overturn forward
Power pushes lower tube body, and upper tube body rotates relative to lower tube body；Meanwhile the 3rd joining beam relative to four-bar linkage rotate, four-bar linkage
Also push.Lower tube body acts on rear wheel support by the second joining beam, and four-bar linkage also acts on rear wheel support；So that trailing wheel branch
Frame is overturn forward along its upper end, and rear wheel support is close to front-wheel support；During, the first joining beam revolves along its both ends
Turn, so as to complete the folding of whole vehicle frame, folding efficiency is high.
Brief description of the drawings
Fig. 1 is side structure schematic diagram of the present utility model.
Fig. 2 is dimensional structure diagram of the present utility model.
Embodiment
Below in conjunction with the accompanying drawings, preferred embodiment of the present utility model is described in further detail.
A kind of stroller frame as shown in Figure 1 and 2, including main body of vehicle frame, and the handrail being arranged on main body of vehicle frame
Frame.
The main body of vehicle frame includes front-wheel support 1 and rear wheel support 2, and front wheels are located on the bottom of front-wheel support 1
Part 11, wheel assembly 12 is located on the bottom of rear wheel support 2.The arm-rest frame includes lower tube body 3 and upper tube body 4, upper tube
The bottom of body 4 and the upper end of lower tube body 3 are hinged；The upper end of front-wheel support 1, the upper end of rear wheel support 2 and down tube
The bottom of body 3 is hinged by threeway part 5；
It is connected between the front-wheel support 1 and rear wheel support 2 by the first joining beam 6, the both ends difference of the first joining beam 6
It is hinged on front-wheel support 1 and rear wheel support 2；It is connected between rear wheel support 2 and lower tube body 3 by the second joining beam 7, second
The both ends of bar 7 are respectively hinged on rear wheel support 2 and lower tube body 3；First joining beam 6 and the second joining beam 7 are on rear wheel support 2
Pin joint is overlapping.The rear wheel support 2 is connected with the bottom of upper tube body 4 by joining beam component, and joining beam component includes upper end
The 3rd joining beam 8 being hinged on upper tube body 4, and bottom are hinged on the four-bar linkage 9 on rear wheel support 2, the 3rd joining beam 8
Bottom and the upper end of four-bar linkage 9 are hinged.Connection sheet 41, the 3rd joining beam 8 are socketed with the bottom of the upper tube body 4
Upper end be hinged in connection sheet 41.
The utility model uses above-mentioned technical proposal, and the technical scheme is related to a kind of stroller frame, the stroller frame
In arm-rest frame and frame body between can carry out linkage folding, folding efficiency is high.Specifically, the stroller frame folds
When, first arm-rest frame is unlocked（Prior art）, then to turnover upper tube body 4 in front of vehicle frame, upper tube body 4 can while upset forward
Force pushes lower tube body 3, and upper tube body 4 rotates relative to lower tube body 3；Meanwhile the 3rd joining beam 8 rotated relative to four-bar linkage 9,
Four-bar linkage 9 also pushes.Lower tube body 3 acts on rear wheel support 2 by the second joining beam 7, and four-bar linkage 9 also acts on rear wheel support 2；
So that rear wheel support 2 is overturn forward along its upper end, rear wheel support 2 is close to front-wheel support 1；During close, first
Joining beam 6 rotates along its both ends, and so as to complete the folding of whole vehicle frame, folding efficiency is high.
