The specific embodiment
As Figure 1-Figure 4: it comprises front vehicle wheel, rear wheel, handlebar 2, front fork 1, vehicle frame, front stall 4, back seat 5, storage battery and motor differential gear 9 the utility model.It is characterized in that: described vehicle frame comprises rear vehicle frame 6 and front vehicle frame 7.Described rear vehicle frame 6 and front vehicle frame 7 are steel structure rectangular frame.Front end at described rear vehicle frame 6 is installed front stall 4, and back seat 5 is installed in the rear end of rear vehicle frame 6, and described rear vehicle frame 6 lower end lateral symmetry are provided with the axis of guide 62, and the described axis of guide 62 two ends are fixed on rear vehicle frame 6 by fixed cover 61.Described place, four jiaos of front vehicle frame 7 lower ends is symmetrically installed with orienting sleeve 71, and described orienting sleeve 71 sliding fits are sleeved on the axis of guide 62, are provided with for being fixed on the tight fixed bolt on the axis of guide 62 on orienting sleeve 71.Gapped in described front stall 4 intermediate fabrication, when front vehicle frame 7 moves backward, the strut bar 3 that is arranged on front vehicle frame 7 front ends moves in described gap.
Described fixed cover 61 is welded on rear vehicle frame 6.
In described rear vehicle frame 6 lower ends, extension adjustment device 8 is installed.Described extension adjustment device 8 comprises support 82, tooth bar 81, gear and rocking bar 83.Described support 82 is fixed on the adapter plate 63 of rear vehicle frame 6.Described tooth bar 81 two ends are laterally arranged in front vehicle frame 7 by connecting panel 72 and bolt.Described gear is arranged on support 82 inside and meshes with tooth bar 81.Described gear is connected with rocking bar 83.
Described extension adjustment device 8 comprises support 82, thread rod, nut and rocking bar 83.Described support 82 is fixed on the adapter plate 63 of rear vehicle frame 6.Described thread rod two ends are laterally arranged in front vehicle frame 7 by connecting panel 72 and bolt.Described nut is arranged on support 82 inside and coordinates with thread rod.Described nut is connected with rocking bar 83.
When the utility model is used, embodiment mono-, when extension adjustment device 8 not being installed, by manual push-and-pull, realizes the flexible of three-wheel vehicle.Push-and-pull is during to end position, and the tight fixed bolt by orienting sleeve 71 belows is fixed on orienting sleeve 71 on the axis of guide 62, prevents that battery-driven car is elastic under steam, protection chaufeur and passenger's personal safety.
Embodiment bis-, in the situation that extension adjustment device 8 is installed, use rack-and-gear type of belt drive.When needs three-wheel vehicle extends, first adjust the tight fixed bolt of the solid orienting sleeve of pine 71 belows, shake again the rocking bar 83 in extension adjustment device 8, by gear driven tooth bar 81, outwards move, tooth bar 81 two ends are connected with two connecting panels 72 of front vehicle frame 7 lower ends by bolt, therefore by tooth bar 81, drive front vehicle frame 7 outwards to move, front vehicle frame 7 stops shaking while moving to end position, tight fixed bolt by orienting sleeve 71 belows is fixed on orienting sleeve 71 on the axis of guide 62, prevents when three-wheel vehicle from travelling flexible back and forth.While using after extending, front stall 4 is operator's saddle, and back seat 5 can be manned.When three-wheel vehicle need to shorten, the same with above-mentioned regulative mode, adjusting order.When front vehicle frame 7 is contracted to end position, the strut bar 3 that is now fixed on front vehicle frame 7 front ends is positioned at the middle gap location of front stall 4.Tighten the tight fixed bolt of orienting sleeve 71 belows.After shortening, back seat 5 is operator's saddle, and front stall 4 can be put article, also can take child, and adult can play a very good protection to child, prevents safety misadventure.
Embodiment tri-, in the situation that extension adjustment device 8 is installed, use nut screw type of belt drive.Identical with the control method of the above embodiments two.
The utility model three-wheel vehicle is contracted to optimization, space after shrink space and contraction is fully used, and the conveniently moving that turns round that travels on road and in entrance to a lane, deposits more convenient, and deposit in indoor more conveniently, avoided long-term outdoor exposure to cause battery-driven car to damage and lost.
