Problems solved by technology

At present, this kind of products mainly include pure electric type and gasoline-electric hybrid type, but the technical bottleneck restricting the development of this type of automobile is that there is no breakthrough in the manufacturing technology of high-power batteries, the continuous driving distance of the automobile is small, charging is troublesome, and the service life of the battery is short. Expensive paradox limits the popularity of such cars

Embodiment Construction

[0024]Specific embodiments of the present invention are as attached figure 1 , that is, the exterior structure of the automobile of the present invention is not much different from the existing various cars, and the key difference is that the automobile of the present invention does not need an engine and a mechanical gearbox; when running on an ordinary road, it relies on the vehicle-mounted battery to provide power to the motor to drive the automobile; When driving on the special non-contact power supply road, rely on the electromagnetic induction transformer installed under the chassis to absorb the electromagnetic waves and alternating magnetic fields transmitted by the two cables on the road surface (such as the attached figure 2 ), a synthetic current is induced in the coil, and this is used as kinetic energy to drive the car to walk, and it can also charge the vehicle battery (such as the attached image 3 ); as long as the car walks along the middle of the two cables ...

Abstract

The invention relates to a wireless electricity-taking car and a road contactless power supply system in road traffic and transport means. In the invention, a power supply is not directly input through electric wire, while a contactless electromagnetic induction transformer arranged under a chassis of a car head indirectly absorbs electric energy in a special power supply cable embedded on a road and charges a storage battery on the car while driving the car to move. Particularly by adopting electric-magnetic-electric contactless power supply and electricity-taking technologies, a 10kV / 15-40KHz high-frequency and high-voltage cable is embedded on a road surface to generate a high-energy vertical electromagnetic wave and an alternating magnetic field; and the transformer arranged under the car is applied with comprehensive induction of the high-frequency electromagnetic wave and the alternating electromagnetic field when the transformer is close to vertical distance of 150-450mm of the cable to induce resultant current in coils and restore magnetic energy into electric energy, thus providing advancing power for the car and charging the battery on the car, and guaranteeing the car can run for longer distance with sufficient electricity after leaving the power supply road. The technology of the invention thoroughly solves the difficult problems of limited energy storage and troublesome charging of the storage battery of the existing similar cars, and explores a new way for energy conservation and emission reduction of the cars.

Description

(1) Technical field: [0001] The invention belongs to the technical field of electromechanical integration and special road wireless power supply system construction, in particular to a wireless power-taking vehicle and road non-contact power supply system. The invention can be applied to the manufacture of electric vehicles and the construction and technical transformation of special power supply roads, and is the technical development direction of future green environmental protection vehicles and their supporting road construction. (two) background technology: [0002] With the introduction of energy-saving emission reduction and green transportation concepts at home and abroad, countries all over the world are investing huge sums of money in the research and development of electric vehicles. At present, this kind of products mainly include pure electric type and gasoline-electric hybrid type, but the technical bottleneck restricting the development of this type of automob...
