It can be seen that the electric bicycle capable of posture detection and intelligent range increase provided by the embodiment comprises a basic structure of a conventional electric bicycle such as a bicycle frame, a front wheel, a rear wheel, a five-way drive motor, a controller, a storage battery and the like, as well as a posture sensor 1 and an exciting motor 2. The electric power-assisted bicycle capable of detecting the gesture and intelligently increasing the range not only can change the output power of the driving motor according to the recognized different states of the bicycle body, but also can enable a rider to tread the exciting motor 2 to replace the original stepping action, so that the phenomenon of empty stepping is avoided; and can be with the electric quantity storage that the person of riding trampled exciting motor 2 and send out in the battery in order to increase the duration, improved the person of riding and experienced the sense greatly.

The implementation of one embodiment of the present utility model will be described in detail below with reference to fig. 1-2, and an explanation of specific structure and function thereof.

The embodiment provides an electric bicycle that can gesture detect and intelligence increase journey, includes electric bicycle main part, and this electric bicycle main part includes: the bicycle comprises a bicycle frame, a front wheel, a rear wheel, five-way wheels, a driving motor, a controller and a storage battery, wherein the bicycle frame, the front wheel, the rear wheel and the five-way wheels (the five-way parts are matched with the upper pedals) form a bicycle (bicycle without electric drive) which is normally ridden, and the driving motor and the controller form an electric booster bicycle which can be driven by manpower or electric drive. The electric bicycle capable of detecting the posture and intelligently increasing the range of the embodiment comprises the following conventional components besides the conventional components of the common electric bicycle: a posture sensor 1 and an exciting motor 2.

Wherein, the attitude sensor 1 is fixed at the center of the front wheel and the rear wheel respectively, the exciting motor 2 is installed at the five-way position and matched with the pedal of the bicycle, namely, the shaft of the exciting motor 2 is connected with the pedal of the bicycle, when the shaft of the exciting motor 2 is connected with the pedal, the diameter of the shaft of the exciting motor 2 is consistent with the installation aperture, the pedal is a standard component, and the outer shaft of the exciting motor 2 is consistent with the aperture of the pedal. In the present embodiment, it is preferable that the rotation shaft of the exciting motor 2 and the rotation shaft of the foothold be integrally provided at the time of actual production. The attitude sensor 1 and the exciting motor 2 are electrically connected to the controller, and the exciting motor 2 is electrically connected to the battery.

An attitude sensor 1 for monitoring the relative attitude of the front and rear wheels. In this embodiment, at least two attitude sensors 1 are provided at the centers of the front wheel and the rear wheel, respectively, for recognizing the relative attitudes of the front wheel and the rear wheel. If the data acquired by the attitude sensor 1 show that the position of the front wheel is higher than that of the rear wheel for a long time, the electric power-assisted bicycle can be identified to be in a climbing state at present, and the controller controls the driving motor to increase the output torque; if the position of the front wheel is monitored to be lower than the rear wheel for a long time, the vehicle body can be identified to be in a downhill state, and at the moment, the driving motor can be stopped from working, and the driving force output of the driving motor is closed. And when the bicycle is not in a riding state, whether the bicycle falls down or not can be identified through the position states of the front wheel and the rear wheel. For example, when the bicycle is not riding, the bicycle is suddenly accelerated in the gravity direction, the acceleration is basically constant, and the duration is also constant, so that the bicycle can be judged to be in the inverted state. When the data acquired by the attitude sensor 1 show that the bicycle is in a road obstacle crossing state, the bicycle controller also controls the output power of the driving motor.

The exciting motor 2 is used for realizing different stepping senses of a rider by changing the magnitude of the current. The traditional electric bicycle is characterized in that a person steps on the bicycle to drive the bicycle to move forward, when the driving motor controls the driving speed to be inconsistent with the speed of the person stepping on the bicycle, the person can feel empty, or the reaction time of the driving motor is slightly slower, so that the output driving force does not keep up, the person who rides the bicycle can feel empty, and the experience of the person who rides the bicycle is poor.

In this embodiment, the exciting motor 2 is installed at the five-way position of the existing electric booster bicycle and is matched with the pedal of the bicycle, so that in the technical scheme, a rider actually connects the coil in the generator when stepping on the pedal, and the coil is rotated by stepping on the pedal. According to the working principle of the generator (faraday's law of electromagnetic induction), the cutting of the magnetically induced wire by the wire (i.e. coil) in the magnetic field is subjected to electromagnetic force and generates current, and the magnitude of the current is related to the cutting speed and the magnetic field strength. The exciting motor 2 changes the magnetic field intensity of the motor, so that the coil receives electromagnetic forces with different magnitudes when rotating inside, and a rider obtains different pedaling feeling.

In addition, in the present embodiment, since the electric generator (i.e. the exciting motor 2) is the essence of the stepping of the rider, the rider can generate electricity when stepping on the bicycle, so that the storage battery can be charged simultaneously during the process of riding the bicycle, thereby increasing the endurance mileage of the electric bicycle. And moreover, the BMS battery system is integrated in the storage battery, so that intelligent management and maintenance of each battery unit are realized, overcharge and overdischarge of the storage battery are prevented, and the functions of prolonging the service life of the battery and monitoring the battery are achieved.

In addition, the rotation speed and the output voltage of the exciting motor 2 are positively correlated, the speed of the cutting induction line can be accurately measured by measuring the output voltage of the exciting motor 2, and the rotation speed of the hub motor is matched according to the power generation voltage, namely, the faster the bicycle is stepped on, the faster the bicycle is run by electric power. In this embodiment, therefore, a voltage measuring device may be installed, which is electrically connected to the exciting motor 2, and determines the rotation speed of the in-wheel motor by detecting the generated voltage of the exciting motor 2, that is, the faster the stepping frequency, the greater the speed of cutting the induction line, the greater the output voltage of the exciting motor 2, and the faster the in-wheel motor runs.

In addition, as a preferred mode of the present embodiment, the electric bicycle capable of gesture detection and intelligent range increase of the present embodiment further includes an electrically controlled speed changing device 3, the electrically controlled speed changing device 3 is mounted on a bicycle handle, and the electrically controlled speed changing device 3 is electrically connected to a driving motor. When a rider wants to change different gears, the electric control speed changing device 3 can be used for controlling different output powers of the driving motor so as to regulate the speed. The gear defines a maximum speed that can be ridden, the higher the gear, the greater the maximum riding speed, and the maximum not exceeding 25KM/H. In addition, in order to facilitate the adjustment of different gear positions, the electrically controlled gear shifting means 3 on the handle is typically provided as a knob.

In summary, compared with the prior art, the method has the following beneficial effects:

1. the utility model relates to an electric power-assisted bicycle capable of detecting gesture and intelligently increasing range, which comprises a basic structure of a conventional electric power-assisted bicycle capable of detecting gesture and intelligently increasing range, such as a bicycle frame, a front wheel, a rear wheel, a five-way drive motor, a controller, a storage battery and the like, as well as a gesture sensor and an excitation motor. The electric power-assisted bicycle capable of detecting the gesture and intelligently increasing the range not only can change the output power of the driving motor according to the recognized states of climbing, descending, passing a road barrier and the like of the bicycle body, but also can enable a rider to tread the exciting motor to replace the original stepping action, so that the phenomenon of empty stepping is avoided; and can be with the electric quantity storage that the person of riding trampled exciting motor and generate electricity in the battery in order to increase the duration, improved the person of riding and experienced the sense greatly.
