Car-electricity-separated electric car

Abstract

The invention belongs to the field of vehicle application and particularly relates to a car-electricity-separated electric car. The car-electricity-separated electric car comprises a car body and an external vehicle-mounted component, wherein the external vehicle-mounted component loaded with a battery is hung on and forms a traction relation with the car body and is provided with a traction terminal d a power terminal, and a traction end and a power end, which are matched with the car body, are correspondingly arranged on the car body. The external vehicle-mounted component is a driven traction component, and wheels in rolling fit with the floor are disposed on the external vehicle-mounted component. The car body bears no battery or only needs to bear a vehicle-mounted battery small in weight, so that self-weight of the car body is reduced greatly, endurance of the car can be improved effectively under no influence on or reduction of self-load of the car. The car-electricity-separated electric car is simple in structure and stable and reliable to operate and has broad market prospect.

Description

technical field [0001] The invention belongs to the field of vehicle applications, and in particular relates to a vehicle-electricity separation type electric vehicle. Background technique [0002] In recent years, especially after the global financial crisis broke out, the development and application of electric vehicles has become a worldwide hot spot. People once placed infinite reverie on this industry, and more and more automobile manufacturers have begun to devote themselves to this direction. However, a few years later, electric vehicles are not as popular as people imagined, but more appear in lively auto shows; the reason is that electric vehicles are different from two-wheeled battery vehicles that can be portable After an electric vehicle has been driven for several hours, it often needs to be parked and charged for a longer period of time. The defects of short battery life and long charging time greatly restrict the subsequent development of electric vehicles. ...

Problems solved by technology

However, the solution to some bottlenecks is accompanied by more practical problems that are difficult to solve, mainly as follows: First, as we all know, as the power source of electric vehicles, the on-board batteries are very heavy, and may even take up half of the total mass of the vehicle body Left and right, this leads to the fact that on the one hand, when it is driving, it is equivalent to the electric car carrying a car battery running, which seriously affects its actual energy efficiency. On the other hand, it can be said that ordinary manpower cannot complete the battery replacement of such a heavy car battery. It often needs to rely on the configuration of special robot arms to cooperate or operate alone. The problems of high use and maintenance costs of the robot arms and long time for a single battery replacement have not been properly solved; secondly, no matter what kind of electric vehicles , the battery placement is realized by the car. In order to achieve the endurance of the vehicle, it is necessary to increase the battery capacity, which needs to be realized by increasing the battery volume, and the increase in battery volume is bound to improve the quality of the battery. , which on the contrary affects the weight of the vehicle, which further causes the accelerated loss of battery power
