Electric automobile using a plurality of electric apparatuses to drive running

Abstract

The invention relates to an electric automobile. The electric automobile comprises an automobile body, an automotive chassis, automotive wheels, a parking mechanism, a control signal input device and a power-drive mechanism, wherein the power-drive mechanism comprises a main drive unit for providing a driving force for the electric automobile in a high-torque operation state, and an auxiliary drive unit for providing a driving force for the electric automobile in a low-torque operation state. The electric automobile also comprises a programmable operating mode control unit for controlling operating conditions of the main drive unit and the auxiliary drive unit according to a control signal input by the control signal input device and the working currents in the main drive unit and the auxiliary drive unit. Therefore, the electric automobile can freely select driving modes with the control of the programmable operating mode control unit, thereby improving the use rate of vehicle-mounted batteries. The electric automobile with the electric drive units has advantages of simple structure, low requirements on use conditions, low manufacture cost and easy promotion and application.

Description

technical field [0001] The invention relates to a motion mechanism using a control program, in particular to an electric vehicle with an automatic obstacle avoidance function using a program control. Background technique [0002] Because electric vehicles have the advantages of no exhaust gas pollution and no influence of oil resources, etc., making them become the development direction of automobile technology. The development of small electric vehicles in China directly follows the design of internal combustion engine cars. The basic principle is: replace the internal combustion engine with an electric motor, and replace the fuel tank with a power supply box. The structural principle remains basically the same; Electric vehicles need on-board electric energy. On electric vehicles, the high-volt-ampere electric energy connected in series by multiple batteries is fixed on the electric vehicle to meet its driving performance requirements. The fixed on-board power supply is th...

Problems solved by technology

[0003] Over the years, the on-board combustion battery has been researched to solve the energy problem of electric vehicles, but it is still experimental. Today, lithium-iron-phosphorus batteries are considered to be suitable for the characteristics of small electric vehicles to provide on-board electric energy. Group supplementary energy and other related problems are still quite a lot, but high-voltage-ampere electric energy is needed to achieve high-speed and high-power engine performance, and multiple batteries are stored in series on the carriage and the characteristics of the car, resulting in a lack of flexibility for supplementary energy. It takes several hours to stop for full charging, maintenance and repair of vehicle power supply, etc., resulting in the inconsistency between the use of small cars and environmental conditions, so that electric small cars are inferior to fuel cars. A new type of vehicle with a hybrid drive is produced, which solves the problem of being able to use fuel to drive when there is a lack of charging conditions or a high-volt-ampere power supply box failure, so as to solve the defects of modern electric vehicle technology

[0004] The application number "CN200620033333.5" in the Chinese Utility Model Patent Application Publication is titled "Electric Vehicle with Time-sharing Direct Drive Front and Rear Wheels", which discloses a time-sharing electric vehicle that directly drives the front and rear wheels. The electric vehicle is characterized in that it uses a high-speed small rated torque permanent magnet brushless DC motor to drive the front wheel of the electric vehicle, and uses a low speed large rated torque permanent magnet brushless DC motor to drive the rear wheel of the electric vehicle, and the front and rear wheels are driven in time-sharing. Each of the two motors is equipped with a controller, and each controller is electrically connected to a special combined speed control handle equipped with two sensors. The controller connected to it transmits signals to complete the driving control; this type of electric vehicle can effectively protect the motor and battery from the harm of high current, but it still cannot solve the problem of the use of high-volt-ampere electric energy batteries, vehicle energy supplementation and vehicle mobility.
