Description of drawings
Fig. 1 has schematically shown scheme drawing of the present utility model.
Fig. 2 has schematically shown mechanics principle figure of the present utility model.
Reference numeral among the figure: 1, support; 2, front-wheel; 3, trailing wheel; 4, seat; 5, jounce bumper; 6, handrail; 7, pedal.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.
As shown in Figure 1, the Electrical Bicycle in the utility model comprises: support 1, front-wheel 2, trailing wheel 3, seat 4 and motor; Front-wheel 2 is connected pivotly with the front end of support 1; Trailing wheel 3 is connected pivotly with the rear end of support 1; One end of seat 4 is connected with support 1, and the other end is connected with support 1 elasticity by jounce bumper 5; Motor drives with front-wheel 2 and is connected.Electrical Bicycle also comprises: electronic gyroscope is installed on the support 1, for detection of Electrical Bicycle center of gravity variation in motion and/or the angle variation of support 1; The balance Control Scheme device is electrically connected with electronic gyroscope, is used for the running according to the testing result control motor of electronic gyroscope inspection.Preferably, the number of trailing wheel 3 is one or two.Preferably, the number of front-wheel 2 is one.Preferably, front-wheel 2 is less than or equal to 0.5 meter with the wheelbase of trailing wheel 3.Preferably, trailing wheel 3 is cardan wheel.Preferably, support 1 is rigidly connected with front-wheel 2.Preferably, motor is the wheel hub motor that is installed in the front-wheel 2.
The wheelbase of front and back wheel is enough to keep vehicle body can not topple over when smooth-ride, but, then is not enough to guarantee steadily initiatively during the weight shift position or when running into road bump and uphill/downhill the occupant.For this reason, the utility model relies on electronic gyroscope and balance Control Scheme device driving front-wheel provides balancing torque, guarantees enough stability and margin of safety.
The space angle signal that the utility model provides according to electronic gyroscope, the motor that drives front-wheel initiatively produces balancing torque, guarantee riding stability, namely increase steady method and prolong the vehicle physical wheelbase with automatically controlled, thereby the vehicle mechanical wheelbase is shortened, scantling of structure reduces, and has alleviated weight, can keep balance in pitch automatically.Occupation space is no more than the human body natural necessary space of standing during riding this vehicle, and can pivot turn in travelling, can before and after two direction runnings, riding it can directly enter elevator, room, or the vehicle of taking pubic transport.
Preferably, Electrical Bicycle also comprises handrail 6, and handrail 6 is connected with support 1.
Preferably, Electrical Bicycle also comprises: 7, two pedals 7 of two pedals are installed on the left and right sides of the wheel shaft of front-wheel 2 respectively.
During use, the occupant rides on the seat, and both feet support ground or are placed on and ride, and this moment, jounce bumper 5 was compressed, and car load keeps natural equilibrium.When centre of body weight turns forward slightly, then support leans forward under the effect of jounce bumper 5 thereupon, this moment, electronic gyroscope detected the angle variation, produce the power of running forward by balance Control Scheme device drive motor, the inclination that this power will suppress support makes it to keep balance, in case occupant's both feet built on stilts, the powered car load of motor advance and continue to keep balance simultaneously.When the hypsokinesis of occupant's centre of body weight, electronic gyroscope and balance Control Scheme device drive motor produce braking force backward, still keep balance in braking, in like manner, and also accelerated movement backward.In the process of advancing, occupant's health is tilted to the left, and the trailing wheel cardan wheel can be swung to the left, the car load travel direction is deflection left naturally, the centnifugal force of this moment can suppress the further inclination of health, so the more high then directional balance of speed is more strong, and principle is the same with two-wheeled cycle.Thus, the occupant can be by the health control working direction that tilts.
Please refer to Fig. 2, under steam in case run into obstacle, car load center of gravity C forward and upward movement, names a person for a particular job and causes and topple if center of gravity is crossed A under effect of inertia.At this moment, electronic gyroscope detects angle and changes, and strengthen the power of running forward by balance Control Scheme device drive motor, and the friction force on tire and ground will provide an antagonistic force moment to suppress center of gravity motion forward, make it to maintain in the safe range.If do not consider the automatically controlled steady effect that increases, then advancing safety allowance depends on the length ratio of AC` and CC`.Existence owing to increasing steady moment is equivalent to AC` length is extended to A`C`, guarantees that it has enough safety allowances, is equivalent to have prolonged the front wheel spindle distance.When moving backward, principle is the same, do not travel backward owing to require high speed, so the safe wheelbase BC` of its trailing wheel can obtain littler.On the other hand, if the situation that electric-control system lost efficacy takes place under steam, for example battery is used up or is insured open circuit motor is run out of steam, to lose and increase steady effect, then center of gravity C descends under the gravity effect naturally, but still is in the range of balance, and car load can keep nature to slide and can not topple immediately, the occupant still can handle to turn to and keep to the side to stop, and has guaranteed necessary system safety;
Owing to adopted such scheme, Electrical Bicycle volume in the utility model is small and exquisite, in light weight, can keep balance automatically, handle simply, do not need specialized training can use as walking-replacing tool, occupation space is no more than the human body natural necessary space of standing during riding this vehicle, and can pivot stud in travelling, can before and after two direction runnings, riding it can directly enter elevator, room, or take bus.
The above is preferred embodiment of the present utility model only, is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
