Referring to Fig. 5 d and Fig. 5 c, when perambulator is carried out by artificial external force, vehicle frame (pipe) is imposed on
External force reaches bottom handle (11), reaches shield wallboard (121), reaches lubrication groove and determine frame (2), due to
Outer frame (4) inner circumferential that moves in turn is supported has frictional force close to rolling pin (3) and ground in face of wheel so that
Rolling pin (3) rotation and the frame (4) that moves in turn outward are rotated, i.e., perambulator is able to move ahead or retreats.
Also be worth going on to say is：
Referring to Fig. 2 and Fig. 6 c parts, foam tire (5) and the faying face structure of the outer frame (4) that moves in turn
Make, it is similar with the counter structure for having wheel at present.
If for the consideration for determining frame (2) friction with lubrication groove compared with the outer frame (4) that moves in turn of limits prevention,
It is semicircle even minor arc discount vibram outlet that the hollow cross sectional shape in acupuncture point (22) can be allowed.
Rolling pin (3) can determine frame (2) periphery and be uniformly distributed in lubrication groove.For reasonable distribution stress,
Outer frame (4) operational flexibility consideration of moving in turn of enhancing, rolling pin (3) can also determine frame (2) in lubrication groove
The top of periphery is relatively dredged, the closeer distribution in bottom.Referring to Fig. 5 a and Fig. 5 d, it is clear that with shield (12)
Two side wall panels (121) realize macropore (24) the place semicircle of connection for lubrication groove determines frame (2) top.
Perambulator travel speed is generally the low middling speed of walking of being grown up, electric children vehicle operation speed
Degree occurs that short distance in short-term 2-3 times or so is grown up walking speed, they compared to can be long-distance long when
The adult vehicles such as motor vehicle, battery truck, the bicycle of operation, belong to fairly slow speed.And
Perambulator and multiply carry infant gross weight it is fairly limited, so plastic also or metalwork lubrication groove determine
Frame (2), move in turn outward frame (4), should possess good anti-deformation intensity；So in this case design
Integrated bottom handle (11), shield (12) though the moulding of part generally suitable material, it
Using reliably and with long-term for perambulator can still be ensured.
