Abstract

The utility model discloses a mini folding motorcycle with a small volume and good safety performance. The prior motorcycle can not be folded with an unmovable frame so the volume is big; and the shock absorbing result is not satisfying; besides, the commonly used drum brake has a poor braking result, a loud noise, a big abrasion, great energy consumption and a poor environment-protecting performance. The utility model is characterized in that the bicycle saddle can be rotated around the installation axle and folded towards the direction of the major beam body so that the whole volume is reduced; the whole width is reduced to a minimum due to the rotation of the handle so that the packing volume is reduced; the shock absorber is arranged inversely between the major beam body and the bicycle saddle for supporting and shock absorbing; a front wheel of disc braking and a back wheel as the output transmission device composed of a mini motor and a voiceless chain ensure the of low noise, small abrasion and stable braking. With the advantages of a simple complete structure, folding ability and guaranteed safety performance, the utility model can be applied to various motorcycles.

Description

The mini electric car

Technical field

The utility model relates to a kind of battery-driven car, the mini electric car that particularly a kind of volume is little, can fold, safety performance is good.

Background technology

Existing battery-driven car generally is the fixed type vehicle frame, can't fold, and volume is big; And bumper is installed on the front and rear wheel hub holder, can't play tangible damping effect; In addition, existing battery-driven car all uses belt or common chain as Power train, and when using belt-driving, balata belt is easily aging, distortion, can't transmit horsepower output fully, then noise is big to use common chain, and wearing and tearing are big, the consumption horsepower output is big, and energy loss is unfavorable for environmental protection; Existing battery-driven car generally adopts rubber drum to stop, and rubber drum stops and wear and tear easily and skid, and braking effect is affected, and has potential safety hazard.

Summary of the invention

At the problems referred to above, the utility model provide a kind of volume little, can fold, mini electric car that safety performance is good.

The technical scheme that its technical matters that solves the utility model adopts is:

The mini electric car, comprise main beam, shock absorber, saddle, handlebar, front fork, front-wheel and trailing wheel, storage battery and power-supply controller of electric are installed in the main beam inner chamber, saddle by one around axle mounting on main beam, shock absorber is inverted and is installed between main beam and the saddle, handlebar is installed in the prenaris top of main beam by column tube, the front fork upper end is installed in main beam prenaris below, the lower end links to each other with the front-wheel of band disc brake, trailing wheel is installed in the afterbody of main beam and opens the retaining place, and its output transmission is made of jointly micromotor that is installed in the main beam inner chamber and silenet chain.

The beneficial effects of the utility model are: because saddle is to be movably arranged on the main beam around axle by one, can rotate around installation shaft, folding to the main beam direction, shock absorber is inverted and is installed between main beam and the saddle, play and support and the directly effect of damping, handlebar can rotate the direction of handlebar by the rotation of column tube, makes integral width drop to minimum, reduces packaging volume; And the front-wheel of band disc brake apparatus and band are formed the trailing wheel of export transmission device jointly by miniature motor and silenet chain, make the noise of battery-driven car little, and it is little to wear and tear, the firm effect of braking, integral structure simply, can fold, safety performance is secure.

The specific embodiment

With reference to Fig. 1, Fig. 2, Fig. 3, Fig. 4, the mini electric car, comprise main beam 1, shock absorber 2, saddle 3, handlebar 4, front fork 5, front-wheel 6 and trailing wheel 7, storage battery 8 and power-supply controller of electric 9 are installed in main beam 1 inner chamber, saddle 2 is to be installed on the main beam 1 by an installation shaft 10, saddle 2 can be around installation shaft 10 rotations, thereby it is folding to the main beam direction, shock absorber 2 is inverted and is installed between main beam 1 and the saddle 3, can play and support and the directly effect of damping, with reference to Fig. 3, Fig. 4, saddle 3 belows are equipped with the lockplate 32 with a plurality of draw-in grooves 31 in irregular shape, and shock absorber 2 and saddle 3 bonded assemblys one end are to be enclosed between the lockplate 32 by movable axis 21, in irregular shape, but one to one in the draw-in groove 31, every pair of corresponding draw-in groove 31 just forms a different gear, and the effect of these gears mainly is to be used for driver according to different weight, regulate the height of saddle 3, make driving speed and safety performance be guaranteed.In addition because the out-of-shape of draw-in groove 31, in case thereby the movable axis 21 of shock absorber 2 pack in the draw-in groove 31, saddle 3 is in a lock-out state, can not skid off easily owing to moving.

With reference to Fig. 1, Fig. 2, handlebar 4 is installed in main beam 1 prenaris top by column tube 41, rivet by screw between column tube 41 and the main beam 1, when needs folded bicycle handle 4, only need unclamp riveting screw, Rotary cloumn pipe 41 just can be threaded to handlebar 4 and main beam 1 same plane, thereby can reduce packaging volume, save resource; In addition, handlebar 4 is equipped with angular adjustment dish 42 with column tube 41 joints, and angular adjustment dish 42 can help height, brachium and the use habit of driver according to oneself, and the angle that leans forward or face upward of adjustment handlebar 4, make the driver drive the most comfortable.

With reference to Fig. 1, Fig. 5, Fig. 6, front fork 5 upper ends are installed in main beam 1 prenaris below, and the lower end links to each other with the front-wheel 6 of band disc brake 61, because disc brake 61 brakes are firm, effective, so, the utility model has adopted disc brake apparatus on front-wheel 6, guarantee the single-piece safety performance; And being installed in the afterbody of main beam 1, trailing wheel 7 opens the retaining place, its output transmission is made of jointly micromotor 71 that is installed in main beam 1 inner chamber and silenet chain 72, in order to reach best noise elimination effect, power wheel 73 on the transmission shaft of micromotor 71 of the present utility model also is to have adopted the noise-less drive wheel, and the hinge wheel 75 that is fixed on the isolator 74 of wheel hub of trailing wheel 7 also is to have adopted noiseless sprocket, thereby make the output transmission of whole trailing wheel 7 reach best noise-less drive effect, reduce single-piece and start noise.

With reference to Fig. 1, Fig. 8, the disc brake line 62 of the disc brake 61 of mini electric car is connected on the handlebar 4, and power-supply controller of electric 9 one ends link to each other with the power lead of headlight 11, the other end links to each other with disc brake line 62, in case by 43 brakes of holding with a firm grip of pulling of the brake on the handlebar 4, brake pulls 43 with power-supply controller of electric 9 short circuits, in this case, refuel all to have in any case and can not drive battery-driven car again, as long as thereby guarantee under unexpected situation, to draw brake to pull 43, just can guarantee the effect of stable brake, guarantee the safety of driving.

With reference to Fig. 1, Fig. 7, the mini electric car, symmetry has headstock lamp hole 12 on main beam 1 prenasal, headlight 11 by screw retention on lampshade, lampshade by screw retention on main beam 1, the electric wire of lampet is connected on the power-supply controller of electric 9 and by it and controls power supply, the effect that headlight 11 not only can play a role in lighting but also have electric weight to show.
