Vehicle-mounted wind power generation energy complementation cruising device

Abstract

The invention discloses a vehicle-mounted wind power generation energy complementation cruising device. A partition plate is fixed in the middle in a barrel and divides the interior of the barrel intoa speed increaser cavity and a generator cavity. A speed increaser is arranged in the speed increaser cavity, and the generator is arranged in the generator cavity. The speed increaser and an outer rotor of the generator are in transmission connection and both rotate around a generator stator shaft in the same direction. The generator stator shaft is fixed to the axis of the barrel. Multiple blades are evenly distributed on the circumferential face of the speed increase and the circumferential face of the outer rotor of the generator. An air inlet and an air outlet are arranged on the side wall of the barrel. In the direction of airflow in the barrel, the air outlet is located on the rear side of the air inlet, and the air inlet direction of the air inlet is the tangential direction of the position where the blades pass through the air inlet. From the above structure, by means of the vehicle-mounted wind power generation energy complementation cruising device, the barrel is divided bythe partition plates into the speed increaser cavity and the generator cavity, the power generation efficiency is improved, and the vehicle speed lower limit value needed for efficient power generation is reduced.

Description

technical field [0001] The invention relates to the technical field of vehicle-mounted wind power generation, in particular to a vehicle-mounted wind power generation device for supplementing energy and endurance. Background technique [0002] In response to the national new energy policy, energy saving and emission reduction, people need to develop sustainable new energy. In this way, solar energy, wind energy, geothermal energy, etc. , the faster the driving speed, the greater the coefficient of wind resistance and the greater the wind resistance. If the wind resistance is not utilized, it will be wasted. When the vehicle is running at high speed, the air will flow relatively to generate wind resistance. Using wind power to generate electricity, and then The electric energy is stored in the battery of the vehicle, so as to provide electric energy for the ignition system, lighting system, air conditioning system, etc. on the vehicle. [0003] The efficiency of the wind ene...

Problems solved by technology

[0004] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a vehicle-mounted wind power generation supplementary endurance device. Driven by the speed increaser and the outer rotor of the generator, it not only improves the efficiency of power generation, but also reduces the lower limit of vehicle speed required for high-efficiency power generation, that is, high-efficiency power generation can be achieved at lower vehicle speeds; The airflow in the air hole A or the air inlet B maximizes the efficiency of the action of the blades, improving the utilization rate of wind energy; through the structure of the windshield block and the connecting rod, the airflow reflected by the blades can act on the connecting rod again, further Improve the utilization rate of wind energy; when the blade rotates to face the air inlet A or the air inlet B, the airflow entering from the air inlet A or the air inlet B will all act on the blade, avoiding when the blade rotates to When facing the air inlet A or the air inlet B, there are other blades in the area between the blade and the air inlet A or the air inlet B, because other blades cannot face the air inlet directly at this time. The airflow entering through hole A or air inlet B will reduce the action rate of the airflow on other blades, thereby reducing the utilization rate of wind energy; The mouth of the hole B extends to the partition and the end plate B to increase the air intake as much as possible to reduce the lower limit of the vehicle speed required for efficient power generation; the air outlet is located at the position where the air inlet rotates 90 degrees along the blade rotation direction , to shorten the flow distance of the airflow in the barrel as much as possible, so as to avoid the reaction force caused by the airflow to other blades; through the function of the air guide device, the air intake volume is further increased to reduce the lower limit of the vehicle speed required for efficient power generation; through the design The height ratio of the air inlet A and the air inlet B is designed at the same time, so as to adjust the final balanced speed ratio between the speed increaser and the outer rotor of the generator. When the height ratio of the air inlet A and the air inlet B is larger, In the final equilibrium state, the higher the rotational speed of the outer rotor of the generator relative to the height of the air inlet A and the air inlet B is equal, the higher the power generation efficiency is relative to the height of the air inlet A and the air inlet B is equal, but the starting efficiency is higher. The lower limit of the vehicle speed required for power generation will increase relative to the situation where the heights of the air inlet A and the air inlet B are equal; when the ratio of the height of the air inlet A to the air inlet B is smaller, the generator in the final equilibrium state The lower the speed of the outer rotor is when the heights of the air inlets A and B are equal, the lower the power generation efficiency is when the heights of the air inlets A and B are equal, but the vehicle speed required to start high-efficiency power generation The lower limit value will be reduced relative to the situation where the heights of the air inlet hole A and the air inlet hole B are equal; to meet different needs, adjust the lower limit value of the vehicle speed required for power generation efficiency and start high-efficiency power generation
