(II) background of the invention

: with the increase of the world population, the consumption of earth resources by human society and the pollution of the environment become important problems for restricting the social progress and the historical development. The development, popularization and popularization of the electric automobile have great significance and effect on solving the problems. The current limit to the popularization of electric automobiles is that the power storage battery has low energy density, less energy storage, high price, short driving mileage and long charging time. The hybrid technology and the continuing old way of using fossil fuels to pollute the air cannot become the final technical solution. The storage battery of all the current running internal combustion automobiles can be used for more than 5 to 10 years under various conditions, and the fundamental reason is that the storage battery is provided with an on-board power generation system. Energy conversion during the operation of the automobile, and research, development, design and application of a dual power supply of the automobile are the future of the development of the electric automobile.

Disclosure of the invention

Dual-power structural system of electric automobile

The inertia force (embodied in high-speed rolling wheels) of the automobile during medium and high-speed running is converted into mechanical energy through a drive axle assembly and a half shaft, and the mechanical energy is turned and accelerated through a differential to form a power source of a vehicle-mounted generator.

A gear (belt pulley) transmission is additionally arranged between the differential mechanism and the generator.

The clutch can be additionally arranged at the front and the rear of the transmission and is used for controlling and adjusting the mechanical energy output by the differential mechanism and supplying the mechanical energy to the generator for power generation.

The connecting rod is connected with the clutch and the rotor shaft of the generator, and can be matched according to the length and the length according to the installation position of the generator.

The generator is reliably arranged in a vehicle chassis by adopting a product matched with a vehicle power storage battery and a driving motor, is connected with the clutch through a connecting rod, receives transmitted mechanical energy, converts the mechanical energy into electric energy and outputs the electric energy through a lead.

The output lead of the generator and the electronic program-controlled regulator need to be matched with the original vehicle, and must be safe and reliable.

The output lead of the generator can be directly connected to the input end circuit of the power storage battery, the power storage battery is charged by the electric energy of the generator, an electronic program-controlled regulator and a circuit design are cancelled, and only the preset control program mode of adjusting the charging and stopping parking of an original vehicle is considered.

The structural system mainly considers the output electric energy of the generator and is directly used for the power consumption of the automobile driving motor. The problems of battery heating, service life reduction and the like caused by direct charging of the storage battery are avoided.

The electric energy output by the generator is connected in parallel with the output end of the power storage battery through the electronic program-controlled regulator, is controlled by the electronic program-controlled regulator, is connected with a high-grade capacitor of the original vehicle, and cuts off the output circuit of the power storage battery according to the output current (voltage) difference, so that the electric energy can be directly used for driving a motor to keep the power consumption of the vehicle running.

When the automobile runs at a high speed, the mechanical energy transmitted by the differential of the drive axle can enable the generator to generate electricity under full load, abundant electric energy meets the power consumption of a driving motor of the automobile so as to keep the running state of the automobile, and surplus electric energy is supplied to a power storage battery for charging through a control circuit of an electronic program-controlled regulator or a special circuit so as to supplement the energy of a storage battery; the electric energy of the power storage battery is independently used during the restarting period after the vehicle is driven at low speed and stops, and the energy storage of the storage battery is fully guaranteed.

When the clutch is separated and the generator stops generating electricity, the electronic program-controlled regulator is disconnected, the full circuit of the vehicle is completely separated from the system circuit, and the design state of the electric vehicle system supplying power for the power storage battery is recovered.
