AI Technical Summary

Technical Problem

Existing roof boxes on vehicles do not utilize wind power to generate electricity, leading to underutilization of a potential energy source and reliance on fossil or renewable fuels for energy supply.

Method used

A wind-powered generator system is integrated into the roof box of vehicles, converting wind energy into electricity for storage and use in the vehicle's battery or grid, eliminating the need for fossil fuels and providing a sustainable energy source.

Benefits of technology

The system generates environmentally friendly electricity without additional space requirements, ensuring a reliable energy supply independent of disruptive factors, and can be adapted to various vehicle models.

Abstract

This invention may be mounted on any means of transport. For illustrative purposes, a passenger car is proposed, although the invention may be mounted on all kinds of means of transport. Consider a car. This invention may be mounted on the roof of the car in the same way as a conventional roof box. The invention resembles a roof box in terms of size and shape. However, it contains one or more generators and turbines which are rotated by wind power and thereby generate electricity. The generated electricity is fed into a storage unit. The storage unit may be located in the roof box, as in figure 1. If the user drives an electric car, they can supply or charge the vehicle directly using the electricity from this invention. If the user drives a fuel-powered vehicle, they can use the electricity generated and stored in this way for other purposes. The electricity may be used at home, while camping, or for other purposes, or may be fed into the public grid.

Description

[0001] What's behind it?

[0002] This invention is intended to benefit environmental protection while simultaneously providing cost-effective, environmentally friendly electricity.

[0003] For minimal acquisition costs, its benefit to people and the environment should be the deciding factor.

[0004] Subject and / or technical field:

[0005] The invention relates to the generation of ecological electricity using wind power.

[0006] Changed:

[0007] The invention relates to the conversion of wind power into environmentally friendly electricity.

[0008] The present invention can be assigned to the field of plant engineering.

[0009] Where can the invention be installed?

[0010] On the roof of a car.

[0011] Changed:

[0012] On the roof of a vehicle.

[0013] The invention can also be installed in trucks, buses, cars, and trains. (Please see the example drawing of the truck - drawings number 3 and 4).

[0014] Description of the invention:

[0015] State of the art

[0016] The currently known roof box serves only the purpose of storing luggage.

[0017] Disadvantages

[0018] The conventional roof box has no inherent disadvantages. However, it is not always used. Instead of transporting or storing an empty roof box, the present invention can be used at any time to generate electricity.

[0019] Task

[0020] The purpose of the present invention is to generate green electricity without the use of fossil or renewable fuels.

[0021] Changed:

[0022] The purpose of the present invention is to convert wind power into environmentally friendly electricity without the use of fossil or renewable fuels.

[0023] Solution

[0024] The environment is relieved of stress and systems are created to generate electricity without the use of fuels.

[0025] Advantages

[0026] No additional rooms or surfaces are required. This invention can be attached to existing objects and systems.

[0027] The impending power shortage can be averted.

[0028] This invention reliably supplies consumers with electricity after every journey - without dependence on disruptive factors.

[0029] Implementation of the invention:

[0030] Drawing number 1 shows an open roof box. Generators are depicted in green. Turbines are attached to these generators. The turbines are powered by wind. During each journey, the (aerodynamic) wind force is used to rotate these turbines, thereby generating electricity in the generators. The generated electricity is fed into the storage system and can subsequently be used as needed, for example, to automatically recharge the vehicle battery, to provide power while camping, or to feed it into the power grid, etc.

[0031] Changed:

[0032] 1. The generators are attached to the box by fastening them to the respective rails located on the bottom of the roof box itself using screws.

[0033] 2. The turbines are attached to the generators following the same principle as wind turbines. These are a smaller version of such wind turbines. 3. The generators are connected to the energy storage system using waterproof power cables and fuses.

[0034] 4. The battery is connected to the car via a fuse box using power lines and fuses. A charging cable runs from the fuse box and ends in a plug. The plug should be manually pulled out of the box and connected to the vehicle's socket.

[0035] This version of the roof box is designed for existing electric vehicles.

[0036] However, it is envisioned that the invention will be installed in electric vehicles in the future, be they cars, trucks, buses, trains, or other vehicles. In this way, manual cable connection and the use of a storage device (as shown, for example, in drawings 3 and 4 for trucks, buses, trains, etc.) can be eliminated, and the power supply from the generators to the vehicle's own storage device can therefore be automated.

[0037] Depending on the vehicle model or loading type of the vehicle, to fit the respective vehicle.

Claims

Patent claims: It is requested that the patent protection cover the following:

1. Project name (AAGG).

2. Product name (DBWKSE) 3. A box equipped with one or more turbines and suitable for generating electricity, or the device as described above.

4. The arrangement of turbines and one or more generators and possibly a power storage device in a box suitable for generating electricity from wind power.
