Description

Self-powered devices for electric vehicles

Technical field: The utility model relates to a power generation and power supply device, in particular to a power generation and power supply device used in electric vehicles.

Background Art: Automobiles are indispensable means of transportation for people. With the development of science and technology, automobiles have been developed from fuel vehicles to electric vehicles, and the application of electric vehicles is becoming more and more common. Electric vehicles generally use electric motors and batteries with large reserves. The batteries drive the motor to rotate, and the motor drives the running mechanism of the car to work. Because the storage capacity of the storage battery of the electric vehicle is limited, the storage battery needs to be charged regularly, and the charging of the storage battery must be carried out at a charging station or a place with a charging power source, which is extremely inconvenient. After the electric vehicle has been running for a period of time, if there is no charging station or charging power source, the electric vehicle will not be able to drive when the battery's electric energy is exhausted, so the use of the electric vehicle will be limited.

Summary of the invention: The purpose of this utility model is to provide a self-power supply device for electric vehicles, mainly to solve the current problems that it is inconvenient to charge the batteries of electric vehicles, and the electric vehicles cannot be used when the electric energy is exhausted in places without charging stations or charging power sources.

The scheme of the present utility model is as follows; the utility model includes a rechargeable battery, a motor, a vehicle load, and a small wind-driven generator. It is realized by setting up a branch circuit in which the switch is connected in series with the motor, and the switch and the load in the vehicle are connected in parallel with the battery.

Beneficial effects of the utility model: the utility model adopts the above-mentioned structure, so that the electric energy generated by the small wind power generator during the driving process of the electric vehicle can provide electric energy for the motor and the load in the vehicle, and at the same time, it can directly charge the storage battery and stop the vehicle Sometimes the storage battery can provide electric energy for loads in the vehicle such as lighting and audio equipment, so as to ensure the normal power consumption of the electric vehicle, avoid the annoyance caused by the failure of the electric vehicle to run when the battery power is exhausted, and reliably realize the purpose of the invention. At the same time, it has the advantages of simple and reasonable structure, convenient and flexible use, stable working performance, safe and reliable power consumption, and suitable for promotion.

BRIEF DESCRIPTION OF THE DRAWINGS: Figure 1 is a schematic diagram of the circuit structure of a self-power supply device for an electric vehicle.

The specific embodiment: by the self-power supply device of the electric vehicle shown in Fig. 1, at first the output ends of at least two wind-driven generators 1 are carried out in parallel, and Fig. 1 is three wind-driven generators 1 are carried out in parallel, to obtain larger DC power supply. Then set the switch 3 and the motor 4, the switch 5 and the load 6 in the vehicle between the positive and negative DC power supplies in series respectively, and then carry out the branch circuit with the storage battery 2 in parallel. During installation, the wind-driven generator 1 can be fixed on the front of the car or at the ventilated place in the front-end chassis cover, the motor 4 is fixed in the chassis, and the rest of the components are arranged in the cab and connected through wires.

When the device is working, the initial electric energy is supplied by the storage battery 2, and during the running process, the small wind-driven generator 1 generates electricity by the wind force generated while moving forward, and the obtained electric energy can be connected to the motor 4 and the load 6 in the vehicle through the switches 3 and 5 respectively. On the one hand, the motor 4 is driven to rotate, and the motor 4 drives the running mechanism of the automobile to work. On the other hand, loads 6 in the car can be connected such as instruments, lighting, audio equipment or the like. Moreover, the excess electric energy can be directly sent to the storage battery 2 for storage. When parking, the small-scale wind generator 1 stops supplying power, and the storage battery 2 provides the stored electric energy to the load 6 in the car to ensure the normal power consumption of the electric car.
