The specific embodiment
Set forth preferred embodiment of the present invention below in conjunction with one of accompanying drawing 1-7 in detail
; Thereby protection scope of the present invention is made more explicit defining so that advantage of the utility model and characteristic can be easier to those skilled in the art will recognize that.
are shown in accompanying drawing 1-4; Among the embodiment of the utility model; It comprises handrail 1, vehicle frame 2, the front-wheel 4 that is arranged at vehicle frame 2 bottoms and trailing wheel 6, vehicle frame 2 bottoms have front-wheel support 3, rear wheel support 5, front-wheel 4 is arranged on the front-wheel support 3.
shown in accompanying drawing 4, vehicle frame 2 is the base portion of this car.Vehicle frame 2 is provided with the car pocket, and children can be sitting on the car pocket in riding the process of spoiling.
shown in accompanying drawing 2, handrail comprises the handrail 11 of the left and right sides and the connecting portion 12 that they are connected to 1, children in riding the process of spoiling this car through buttress this handrail 1 to control the direction of this car.
are shown in accompanying drawing 4; Pivot 7 comprise with handrail 1 rotate in the same way first turning set 8, with connecting rod mechanism 12 rotate bonded assembly second drive sleeve, plectrum; Plectrum is arranged between first turning set 8 and second turning set 9; When first turning set 8 rotated, second turning set, 9 relative first turning set, 8 opposite directions were rotated.
are shown in accompanying drawing 1-4; Lay respectively at left and right tumbler 10 rotating being arranged on the rear wheel support 5 of the left and right sides; Two trailing wheels 6 about being respectively arranged with on left and right two tumblers 10 are connected with a deflecting bar 13 between the left and right sides tumbler 10.
shown in accompanying drawing 1 and 4, connecting rod mechanism 12 comprises boxed rod 121 and lower link 122.Boxed rod 121 is dynamically connected with following rotary sleeve according to legend, and lower link 122 rotates with the center of deflecting bar 13 and is connected.When rotary sleeve drives boxed rod 121 rotation action instantly; Boxed rod 121 drives lower link 122 and rotates; Lower link 122 drives deflecting bar 13 along himself axis direction slip; Deflecting bar 13 drives tumbler 10 around rear wheel support 5 rotations, and the cardinal principle middle part of lower link 122 connects with rear wheel support 5 mutually rotationally.
