Abstract
The utility model discloses a long distance run electric bicycle, which is characterized in low centre of gravity, far road mileage, and can load high power capacity accumulator; when the bicycle is in low speed, the traction force can be enlarged. The utility model has the technical proposal that accumulator cells which are used for power supply motivation are arranged on the both sides of a shaft of a rear driving wheel respectively; two direct current electric motors are arranged on a cell box 4 and a cell box 4 respectively for driving bicycle run; When the bicycle runs, a motor A is started-up to make the wheels in a low speeds, after reaching to a certain speed, the A is closed; When climbs a steep slope, a motor B is started-up to make the bicycle in a high speed, the A and the B are started-up at the same time and human can also power-assisted at the same time. The bicycle adopts a thin body long-life cell, when the capacity is 60-105 ah, a direct leading wire between the motor and the cell is adopted to control the speed.
Description
Since bicycle comes out,, taken up an area of the welcome that factor such as few has been subjected to people because it is without fuel, along with society constantly develops, people produce already without fuel, the Electrical Bicycle that noise is little, but popular Electrical Bicycle also exists many defectives at present.As the Electrical Bicycle that Shanghai No.2 Bicycle Works produces, the storage battery that has adopted two 12 volts of 36 ampere-hours is as the energy, so travelled distance is not far.Fill once electricity and only can travel about 60 kilometers, because the capacity of storage battery is too little, and many users are behind a round destination, to use up often, use the words of battery under this situation repeatedly, the life-span of battery does not reach half of ordinary life, so this battery of electric bicycle life-span is not long.In addition, this Electrical Bicycle is to utilize semiconductor devices to come speed governing, the fault rate height, because of this car is the purpose that the terminal voltage of adjusting electrical motor reaches speed governing, have only 24 volts of voltages are turned down, again so can't increase the tractive force of motor, grade climbing performance is poor, is only applicable to Plain, city.A kind of Electrical Bicycle is now also arranged, the patent No. is 8720373.6, this kind Electrical Bicycle has had certain progress than the former, as installed equipment such as shock absorber light additional, but being storage battery with 36 ampere-hours, this Electrical Bicycle is contained under the seat, the beam of battery box as the Electrical Bicycle frame, speed governing has been adopted the storage battery string, method in parallel changes the terminal voltage of electrical motor, and promptly the voltage at the electrical motor two ends can have 12 volts, 24 volts two kinds, has reached the purpose of speed governing.But still there is following shortcoming in this Electrical Bicycle: 1, the center of gravity of battery-driven car is too high.Reason is: storage battery repeatedly is contained under the seat, and storage battery is a very big device of quality, with battery repeatedly dress get up, the center of gravity of having increased battery-driven car virtually so just makes Electrical Bicycle increase degree of risk in riding and depositing.2, this Electrical Bicycle also can't strengthen capacity of cell, and travelled distance is also not far, and filling once electricity also is only can travel about 60 kilometers.3, this bicycle speed-regulating device only can be supplied with 24 volts of electrical motors, 12 volts of two kinds of electro-motive forces, be that 24 volts of will normally use become 12 volts, so can't increase tractive force, grade climbing performance is also poor, also be to be applicable to the Plain, city, add that 12 volts and 24 volts differ too big, according to power W and electric current I, the relation between the voltage V, i.e. W=IV, electric power one regularly, voltage reduces, and electric current can raise, when powering to motor with 12 volts, voltage is too low, electric current I will raise, and the coil temperature in the motor will sharply rise, so the electrical fault rate of this Electrical Bicycle is very high, moreover in Electrical Motor, also not allowing rated voltage is that 24 volts electrical motor is connected in 12 volts the circuit and uses.In order to overcome above-mentioned defective, the inventor has designed a kind of Electrical Bicycle that can travel at a distance, and this Electrical Bicycle has following advantage: 1, storage battery is selected high capacity cell for use; The 60-105 ampere-hour can be used, so travelled distance is far away, when selecting 75 ampere-hour storage batterys for use, whenever fills once electricity, and travelled distance can reach 140 kilometers.
2, center of gravity is extremely low.Reason is: car is made the formula that leans against of novelty as shown in Figure 1, battery adopts slim, be contained on the rear drive wheel shaft respectively, wherein 1 is the special-purpose vehicle frame of storage battery car, 2 is the flywheel group, 3,3 ' be storage battery, 4,4 ' be battery box (among the figure 4 ', 3 ' do not draw), 5 is the drive wheel backshaft skin, 6 is shelf, 7 is the movable Luo silk nails of shelf, 8,12 for leaning against, the movable Luo silk of shelf, 11 for leaning against, the shared clamping plate of shelf, the 10th, lean against the back control stalk that contracts before stretching, 14 for leaning against pinning, and 15 is the backrest locking nail hole, and 13 is cushion, wherein become flexible 7,8,12,14 o'clock, shelf 6, lean against 9 contract before stretching after, can fall on shelf 69 when needing, lean against 9 and become seat cushion this moment.Among a figure among Fig. 4 29,30 is the seat cushion back slotted eye that contracts before stretching, car also can be made shape as shown in Figure 2, wherein 1 ', 2 ', 3 ', 4 ', 5 ' identical with 1,2,3,4,5 effect among Fig. 1, because the thin type battery that has adopted my special Electrical Bicycle for this reason to manufacture and design, overall width only is a 0.38-0.40 rice.
3, during the car dead slow, can increasing traction, grade climbing performance is excellent.
4, speed governing adopted novel motor and storage battery directly to go between method that speed governing combines, fault rate is very low, storage battery has adopted me (to apply for national patent by design-calculated thin type long life large-capacity battery, application number is 91224891.2), normal use can reach more than 4 years, the electro-motive force of the every single lattice of this storage battery also is 2 volts, the electro-motive force of every battery also is 12 volts, when producing storage battery, at 4 volts, 6 volts, 8 volts, 10 volts, load onto binding post respectively in 12 volts of point of connection, connect with other one 12 volts storage battery, can get 16 volts, 18 volts, 20 volts, 22 volts, 24 volts of five kinds of different electro-motive forces, when normal the use with 24 volts grades, need when slightly slow with 22 volts, when slow again with 20 volts or 18 volts, 16 volts, close when slow again and can make the high-revolving motor B of car, start and to make the low-tach motor A of car, Here it is so-called motor, the speed regulation method that storage battery directly goes between and combines, without change speed gear box five kinds or six kinds of speed changes can be arranged also, and when driving with A, the tractive force of output is big, and this means have solved in the present society many anosis of existing electric bicycle speed-regulating partial fault, or the unfavorable problem of speed change means.
