Detailed description of the invention

The utility model will be further described below in conjunction with the accompanying drawings.

As Figure 1-4, the scooter of a kind of safety and firmness, including headstock 1, vehicle body 3 and wheel, headstock 1 is T word bar, Headstock 1 and vehicle body 3 are connected by inclined tube 2 combination, and inclined tube 2 upper end is welded with head tube 21, and lower end is the transverse tube 22 extended, headstock T The montant end of word bar 1 inserts head tube 21 and uses locking member 4 to lock, and head tube 21 lower end connects wheel hub frame 5, connects in wheel hub frame 5 Cock wheel hub 6 and front-wheel 7, vehicle body 3 inner chamber front end is provided with fixture 8, has 4 fixing holes 81 above fixture 8, has 2 below admittedly Determining hole 82, the transverse tube 22 of extension inserts fixture 8, stamps screw locking at fixing hole and fixes, and vehicle body 3 inner chamber is additionally provided with connection Rechargeable battery 9, motor 10 and gear train 11, rechargeable battery 9, motor 10 and gear train 11 be all disposed within the position fixed, point It is not arranged on inside battery case, motor housing and gear-box.The driven pulley of gear train 11 and two trailing wheels 13 are by rotary shaft 12 even Connecing, rotary shaft 12 uses hexagonal rib type.Headstock 1 is provided with startup display lamp 18, and handling position has antiskid glue sleeve 19.

As it is shown in figure 5, complete vehicle structure after scooter installation, the pedal 14 of vehicle body 3 is provided with slipmat 15.After vehicle body Wheel cap 16 is connected with tailstock plate 17 one, and tailstock plate 17 is to raising up.

The T word bar 1 of headstock and inclined tube 2 use aluminium profiles tubing, and material is light, and load-bearing is good, it is possible to ensure scooter rigidity and Intensity reaches the design requirement of load-bearing 75kg.The headstock 1 of T word bar, inclined tube 2 and the combination angle of vehicle body 3 inner fixing member 8 and dress Join so that complete vehicle structure is more firm, resistance to fall, 6 fixing holes up and down of fixture distribution, not only act as fixation, moreover it is possible to Twisting rollover during effectively preventing scooter from using, strengthens the function of anti-skidding shatter-resistant.1 front-wheel and 2 trailing wheels Combination, scooter is sliding when, the most steady, it is not easy to tilts, when child is at play, also will not fall down easily.
