The folding automatic bicycle has the advantages of scientific structure, simplicity in manufacturing, portability, environment friendliness and the like and is pretty wide in market prospect.

Description

Folding electric bicycle

One, technical field

The invention belongs to the vehicle, relate in particular to a kind of rational in infrastructure, folding electric bicycle of being convenient for carrying.

two, technical background

At present, battery-driven car has become the important vehicle of one of people's trip, and it has environmental protection, cheapness, quick, the literary composition advantage such as just, deeply welcomed by the people, has wide market development prospect.But although existing battery-driven car is of a great variety on market, ubiquity is parked and is taken up room comparatively greatly, and problems such as carrying is inconvenient in remote trip.

Three, summary of the invention

Object of the present invention be exactly people a kind of scientific structure is provided, manufacture simple, easy to carry, use comfortable, deposit the folding electric bicycle do not taken up space.

Technical scheme of the present invention is: it is made up of parts such as tap, front and back wheel, seat cushion, vehicle frame, electric powerplant and brake gears, described vehicle frame is by leading bowl group, splendid attire battery and pacify motorized support and lower coupling pole forms, tap bowl group is connected by axis with frame upper, bottom is connected by front rod, connection handle and rear connecting rod, tap and brake gear hand handle are installed in the top of tap bowl group, and front fork and front vehicle wheel are installed in bottom.The bottom of support is arranged by the messenger chain wheel shaft of direct motor drive and back vent, and sprocket shaft side is provided with driving chain wheel and is connected with the sprocket wheel that rear vehicle shaft is arranged by chain.Seat cushion is fixedly mounted on the pipe link terminal part be set on axis, around central axis, can be provided with the axle bed by adapter shaft mount pad bar bottom it, be provided with thread-locking ring below seat bar, can be folded in pipe link around adapter shaft half-twist.Support lower chain wheel shaft has been set with the seat support pipe that top arranges screw thread, and the two ends of messenger chain wheel shaft are also provided with the crank installing pedal pipe link, and pedal and pipe link are all foldable on crank.

The invention has the beneficial effects as follows: owing to being the bascule be made up of leading bowl group, support and lower coupling pole by Vehicle Frame Design, thus make the front and back wheel of vehicle and seat cushion all can carry out folding and launching around support, have easy to carry, use the advantages such as comfortable, very easily popularize, market outlook are very wide.

Below in conjunction with accompanying drawing, the invention will be further described.

Five, detailed description of the invention

General idea of the present invention is for by leading bowl group 5, splendid attire battery with pacify motorized support 15 and lower coupling pole forms bascule by Vehicle Frame Design, namely leading bowl group 5 is connected by axis 4 with support 15 top, and bottom is connected by front rod 7, connection handle 6 and rear connecting rod 20.Leading bowl group 5 can be rotated and front rod 7, rear connecting rod 20 and connection handle 6 folding and carry out folding and launching around support 15 around axis 4.The top installation tap 2 of tap bowl group 5 and brake gear hand are 1, and front fork 8 and front vehicle wheel 9 are installed in bottom; The bottom of support 15 is arranged by the messenger chain wheel shaft of direct motor drive and back vent, and sprocket shaft side is provided with driving chain wheel 17 and is connected with the sprocket wheel that rear wheel 19 axle is arranged by chain; Seat cushion 10 is fixedly mounted on pipe link 3 terminal part be set on axis 4, can rotate around axis 4, be provided with the axle bed by adapter shaft 11 mount pad bar 12 bottom it, below seat bar 12, be provided with thread-locking ring 13, can be folded in pipe link 3 around adapter shaft 11 half-twist; Support 15 lower chain wheel shaft has been set with the seat support pipe 14 that top arranges screw thread, can have pivoted in support 15, the two ends of messenger chain wheel shaft are also provided with the crank 16 installing pedal pipe link, and pedal and pipe link are all foldable on crank 16.Its foldable structure principle is: form the thread connecting mode common support that links together by thread-locking ring 13 between seat bar 12 and seat support link 14 and seat cushion 10, front rod 7 and rear connecting rod 20 are by linking together with the screw connecting mode of connection handle 6, can fold for point of inflection by connection handle 6 each other, support 15, axle sleeve connection mode by axis 4 between leading bowl group 5 and pipe link 3 link together.Folding mode simple and fast, when needs are folding time, only need to unclamp thread-locking ring 13, just can separate between seat bar 12 and seat support pipe 14, seat bar 12 around with seat cushion 10 bottom adapter shaft 11 axle center half-twist to be folded to pipe link 3 inner, to be folded to support 15 inner around rotating 45 ° with support 15 chain shaft axle center for seat support pipe 14; Then leading 2 parts rotate 60 °, finally pull connection handle 6, folding front rod 7 and rear connecting rod 20, thus band motor vehicles bodies is folding, realizes the whole folding process of bicycle.When implementing of the present invention, when it is desired to be used, only each parts need be launched as shown in Figure 1, user and rideable, for people's trip offers convenience.When people need to leave in go out to carry with in or beyond less space, only need be folded (as shown in Figure 6), collect for people or carry and provide convenience.Concrete folding step is:

The first step: unclamp thread-locking ring 13, seat pipe 14 and seat bar 12 are separated, and then seat bar 12 rotates among pipe link 3 (as shown in Figure 2) around the adapter shaft 11 with seat cushion 10.

Second step: after folding income pipe link 3 inside of present bar 1, seat support pipe 14 rotates to support 15 inside (as shown in Figure 3) around the axle center of the sprocket shaft with support 15 bottom.

3rd step: pipe link 3 with seat cushion 10 together with seat bar 12 around the position (as shown in Figure 4) that axis 4 axle center rotary folding overlaps as support 15.

4th step: tap 2 first rotates to certain angle around adapter shaft, is folding prepare (as Fig. 5) of car body afterwards.

Article 5: bicycle front rod 7 and rear connecting rod 20 are with connection handle 6 for folds, and drive tap 2 partially folded, thus it is folding to realize car body, whole folding process so far terminates (as shown in Figure 6).
