The utility model can be matched with the bicycle without changing the original structure of a bicycle body; the utility model can realize the functions of speed aid, speed regulation, automatic speed limitation for downgrade, urgent braking, feedback charging, etc. Compared with the existing electric bicycle, the utility model has low price, and can increase road mileage of one-time charge of the power supply.

Description

The bicycle speeding-aid device

The utility model relates to dynamo-electric field, is a kind of device of realizing the bicycle speed-raising.

Bicycle is the highest vehicle of present popularity rate, but length will consume bigger muscle power apart from stepping on row.Motor bike can less consuming one's strength and realize quick long journey, and is for the moment rotten in big small city apoplexy in the last few years, expands and expands, but again because the weightening finish of oily contaminated vapor, and the motorway accident such as increases at reason, the control development of having to of present many cities.For these reasons, battery-driven car just arises at the historic moment on the market, and the stroke that once charges is short, et out of order needs professional's dismounting maintenance but it exists again, and on price, to most popular, particularly vast peasant brother is difficult to present stage bear.

The utility model has proposed a kind of bicycle speeding-aid device of simple structure at some deficiency of present battery-driven car, can reach speed-raising under the situation that does not change the bicycle original design, speed governing is advanced, and increases the purpose of the travelled distance that once charges.

Technical solutions of the utility model:

The bicycle speeding-aid device mainly is made up of electrical motor and control setup thereof, power-transfer clutch, rotor wheel, electrical motor is a pair of and symmetrical being installed on the back fork of bicycle, the power supply of control device of electric motor partly is installed in the bicycle tripod, the master unit of power-transfer clutch is positioned between the back vent of electrical motor top, and passing through the elasticity wrist that comprised motor casing in succession, the external part of motor reel is equipped with rotor wheel.

Now provide accompanying drawing.

Accompanying drawing 1 is installed in structural representation on the bicycle for the utility model master unit.

Accompanying drawing 2 is the utility model control device of electric motor assembly connection diagram.

Below be described further in conjunction with the accompanying drawings again.

Pair of motors 11 shell lower ends respectively have rotation fixed card 13 that two electrical motors respectively are fixed on two back vents 14 of bicycle, and ear 10 is covered in electrical motor 11 shells upper end.Power-transfer clutch is positioned at the bicycle schoolbag frame between 2 times, the back fork of bicycle of electrical motor top, its profile is crab claw structure, constitute one by rotating shaft 3, square shaft 6, waist drum wheel 5, spring 4, crab arm 7, elasticity wrist 8, clutch handle 18, two crab arm 7 one ends are enclosed within the rotating shaft 3, and the other end connects the upper end of wrist 8.The primary clustering of motor control assembly is power supply E, safety fuse cutout F, car stop interlocking switch Z, driving K switch, diode D, resistance R and constitute loops with two electrical motors in parallel 11.Sequence number 1,2,14,15,16,17,19 all belongs to the parts of bicycle own in the accompanying drawing in addition.

The utility model uses real side:

This speeding-aid device is installed complete on request.During work, clutch handle 18 presses down, the square shaft 6, the waist drum wheel that are connected as a single entity with this handle rotate to position shown in Figure 1 simultaneously, spring 4 one ends are fixed in the rotating shaft, the other end is fixed on the crab arm, its clamping crab arm 7, this Clamping force act on electrical motor by the elasticity wrist and with its bonded assembly motor casing upper end cover ear again.The deep-slotted chip breaker and the bicycle rear cover tire 16 of the rotor wheel 9 of motor shaft end compress applying, and Baltimore groove and wheel steel ring 17 compress applying (seeing accompanying drawing 1).By the down train K switch, energized, motor reel drives relatively rotating of rotor wheel and then orders about trailing wheel jointly and advance forward.The driving K switch of control device of electric motor generally is contained on the right handgrip, if point driving switch K can control road speed freely.From accompanying drawing 2 as seen, the two ends of driving K switch power diode D in parallel, when the bicycle descending or when running into other and needing Reduced Speed Now, disconnect the driving K switch and just can implement the feedback charging storage battery, electrical motor becomes generator operation, prolong the discharge time of storage battery, increased once electrically-charged stroke mileage.When running into emergency situation in the bicycle fast running process, hold car brake lever hand at once, the normally closed interlock disconnection that makes the car that is contained on the handlebar stop interlocking switch Z, cut off motor power, and then the car normally open contact closure of interlock switch Z of stopping, the R short circuit, implement urgent resistance braking, guaranteed traffic safety.During the utility model place off working state, cut off the electricity supply, drive waist drum 5 rotations with carrying a squareness square shaft 6 on the clutch handle 18 simultaneously, the length of waist drum wheel is through the transverse horizontal position, outside the both sides crab claw 7 were pressed to, through elasticity wrist 8, electrical motor upper end cover ear 10 also outwards moved motor case, rotor wheel leaves bicycle quick, finishes separation function.The electrical motor that the utility model adopted is the rare-earth Nd-Fe-B electrical motor, and motor brush 12 takes outer mounting means conveniently replaced, favourable M R.Rotor wheel adopts the nylon material of high-strength high temperature-resistant, be cast with the muscle line with the arc groove face of bicycle thickening Da Pi 16 contact positions, can increase friction coefficient, it is that the obstructed square hole that does not pass the wheel center cooperates with the electrical motor projecting shaft, to reach the anti-greatly again rainwater of torsion, purpose easy to assembly.

In sum, the utility model reaches design purpose.Scooter 18-20 kilometer when experimental test can reach 50 kilometers with the conventional accumulators of the 12v40 ampere-hour travelled distance that once charges.Low cost of manufacture can satisfy general popular operating needs.
