The slope gradient sensor transmits the signal to the controller; the controller adjusts the output working voltage and the working current according to the signal of the sensor through a CPU software program in the circuit, so as to control the rotation velocity and the power of the motor, and to realize the energy saving effect in the riding. The electric bicycle adopts a slope gradient sensor to perform different control for different riding road statuses, so that the bicycle riding is safer in higher efficiency, and the service life of the cell can be prolonged.

Description

A kind of Electrical Bicycle with Slope Transducer control

Technical field

The utility model belongs to the Electrical Bicycle class.

Background technology

The fast development of building along with modern city, and the enhancing of people's energy-conserving and environment-protective consciousness, battery-driven car economic, convenient, environmental protection have become increasing people and have selected the vehicle of going on a journey.But the battery-driven car of producing is not all installed Slope Transducer at present, can't judge that the road surface is smooth or goes up a slope or descending, so the controller master mode also is fixing, can not change.When the user is in climbing, if electric current is not enough, be that under power is big, rotating speed of motor can be very low, and efficient at this moment will be very low, and promptly most energy becomes heat energy and dissipates, wasted energy, owing to produce heat in a large number, the metal-oxide-semiconductor in the controller is easy to sustain damage simultaneously, and the life-span shortens greatly; When the user was in descending, if controller does not carry out energy recovery control, the battery-driven car riding speed can constantly be accelerated, and the bicyclist can bring the unsafe hidden danger of drag; When the user is in level road, in case the electric vehicle loading duty ratio is bigger, at this moment the battery-driven car horsepower output is just bigger, the long-term overrate of battery-driven car working current meeting, even near cut-off current, battery-driven car is operated in this state, speed is fast, windage is just big, and power consumption is bigger, and can bring the bad potential safety hazard of drag performance.

Summary of the invention

The purpose of this utility model is at the deficiencies in the prior art, and the Electrical Bicycle that a kind of structure is more scientific and reasonable, different track states detected safer, band Slope Transducer that efficient the is higher control of control is provided.

The technical solution of the utility model is as follows:

A kind of Electrical Bicycle with Slope Transducer control, comprise car body, battery, controller, motor, it is characterized in that: controller has connected Slope Transducer, Slope Transducer is contained on the pedestal, constitute, and link to each other with controller by horizontal columns, two luminotrons, two cooresponding adoptors, signal processors by the corresponding signal lines of sensor.

The utility model sends voltage signal respectively by the detected upward slope of Slope Transducer, descending, level road and gives controller, controller is exported corresponding work voltage and working current according to sensor signal by CPU software program adjustment in the circuit, control rotating speed of motor and watt level reach the energy-saving effect of riding.The utility model has adopted Slope Transducer, and different track states is carried out different control, makes that driving is safer, efficient is higher, and can effectively prolong the service life of battery.

The specific embodiment

Shown in Fig. 1,3, a kind of Electrical Bicycle with Slope Transducer control, comprise car body 1, battery 2, controller 3, motor 4, it is characterized in that: controller 3 has connected Slope Transducer 5, as shown in Figure 2, Slope Transducer 5 is contained on the pedestal 6, is made of horizontal columns 51, luminotron A52, luminotron B53, adoptor A54, adoptor B55, signal processor 56, and link to each other with controller 3 by corresponding signal lines A71, the B72 of sensor, have bubble in the horizontal columns.

The utility model Slope Transducer 5 is that the fixed orifice by pedestal 6 is installed on the battery-driven car with screw, stay on the level road at vehicle and to adjust sensor fixed orifice position and make the bubble in the sensor be positioned at the midway location of horizontal columns 51, and corresponding signal lines A71, the B72 of sensor output linked to each other with controller 3.When battery-driven car is in the level road state, in the middle of bubble in the horizontal columns 51 is positioned at, at this moment luminotron A52, luminotron B53 transmit by horizontal columns, adoptor A54, adoptor B55 receive transmitting of luminotron A52, luminotron B53 respectively, export high level respectively by signal processor 56; And when battery-driven car is in the upward slope state, bubble in the horizontal columns is positioned at the front portion, at this moment luminotron A52 transmits by horizontal columns, adoptor A54 receives transmitting of luminotron A52, by signal wire (SW) A71 output high level, bubble is aimed in luminotron B53 emission and adoptor B55 can not receive signal, by signal wire (SW) B72 line output low level; Same when battery-driven car is in descending, just with the upward slope opposite states, signal wire (SW) A71 output low level, signal wire (SW) B72 exports high level; Signal wire (SW) inputs to the judgement signal of controller as the controller master mode.

The utility model is when being in the upward slope state, on the Slope Transducer, the descending signal wire (SW) is output low level and high level signal respectively, controller is received " 0 ", Control Software incision controller needs big current work behind " 1 " signal, the power of controller will increase, rotating speed can improve, after rotating speed improves, efficient will significantly improve, efficient improves can make the real output function improve simultaneously again, thereby rotating speed improves, and this is a benign cycle, the heat of controller generation at this moment will reduce, thereby can reduce damage, increase the service life of controller, also strengthen the grade climbing performance of car load metal-oxide-semiconductor; When being in the descending state, Slope Transducer is gone up a slope and the descending signal wire (SW) is exported high level and low level signal respectively, after controller is received " 1 ", " 0 " signal, and detect motor speed above rated speed of rotation, controller enters energy recovery automatically, electronics assist brake system works, the battery-driven car Reduced Speed Now, and battery is carried out energy recharge; When being in the level road state, Slope Transducer is gone up a slope and the descending signal wire (SW) is exported high level and high level signal respectively, after controller was received " 1 ", " 1 " signal, this moment, the load-carrying load of vehicle was bigger again, surpassed load current value in case detect motor working current, controller enters the speed limit state automatically, reduce windage, reduce working current, prolong mileages of continuation, and the assurance deceleration and stopping performance, riding safety can increase substantially.
