Vehicle frame be perambulator as chief component, baby carriage frame structure determines the most of function of perambulator.But, it is 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
Frame designs unreasonable on the interaction relation between arm-rest frame and frame body, 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
In 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：
Stroller frame, including frame body, and the arm-rest frame being arranged in frame body；It is characterized in that：It is described
Frame body includes front-wheel support and rear wheel support, and arm-rest frame includes upper tube body and lower tube body；The bottom of upper tube body and down tube
The upper end linkage of body, the upper end of the bottom of lower tube body, the upper end of front-wheel support and rear wheel support is hinged composition
Pin joint A；It is connected between the arm-rest frame and frame body by linkage unit, linkage unit includes being fixed on lower tube body
The first joining beam on bottom, and the second joining beam being hinged with the first joining beam, and the 3rd be hinged on front-wheel support
Joining beam, and the four-bar linkage being hinged on rear wheel support；Second joining beam, the 3rd joining beam and four-bar linkage are hinged composition
Pin joint B.
Preferably, the upper end of first joining beam is fixed on the bottom of lower tube body, the leading section of the 3rd joining beam
It is hinged on front-wheel support, the rearward end of four-bar linkage is hinged on rear wheel support, the upper end of the second joining beam and the first joining beam
Bottom be hinged, the leading section of the bottom of the second joining beam, the rearward end of the 3rd joining beam and four-bar linkage is hinged composition hinge
Contact B.
Preferably, the bottom of the front-wheel support is provided with front component, after the bottom of rear wheel support is provided with
Wheel assembly.
Preferably, the bottom of the upper tube body and the upper end of lower tube body are hinged.
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, is easy to routine use.Specifically, the baby
When youngster's vehicle carriage is folded, first arm-rest frame is unlocked（Prior art）, then to turnover upper tube body in front of vehicle frame, upper tube body is turned over forward
It can be exerted a force while turning and push lower tube body, lower tube body is downwardly turned over along interface point A；Further, first in linkage unit
Bar is moved with lower tube body, and drives the second joining beam lifting, and the 3rd joining beam and four-bar linkage are made during the second joining beam lifting along hinge
Contact B opposed juxtapositions；Meanwhile, the 3rd joining beam and four-bar linkage also drive front-wheel support and rear wheel support along interface point A relatively simultaneously
Row；It is achieved between arm-rest frame and frame body that linkage folding can be carried out, combines existing stroller frame on basis herein
Seating frame foldable structure be that perambulator full vehicle frame folding can be achieved.
Brief description of the drawings
Fig. 1 is deployed configuration schematic diagram of the present utility model.
Fig. 2 is gathering process schematic 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.
Stroller frame as shown in Figure 1 and 2, including frame body, and the arm-rest frame being arranged in frame body.Institute
Stating frame body includes front-wheel support 11 and rear wheel support 12, and the bottom of front-wheel support 11 is provided with front component 13, trailing wheel
The bottom of support 12 is provided with wheel assembly 14.
The arm-rest frame includes upper tube body 21 and lower tube body 22, and the bottom of upper tube body 21 joins with the upper end of lower tube body 22
Dynamic, general available scheme is that the bottom and the upper end of lower tube body 22 of the upper tube body 21 are hinged.The lower tube body
The upper end of 22 bottom, the upper end of front-wheel support 11 and rear wheel support 12 is hinged composition pin joint A；The handrail
It is connected between frame and frame body by linkage unit, linkage unit includes first be fixed on the bottom of lower tube body 22
Joining beam 31, and the second joining beam 32 being hinged with the first joining beam 31, and the 3rd joining beam 33 being hinged on front-wheel support 11,
