Problems solved by technology

Although there are already a variety of vehicle-mounted wind power generation technologies, these vehicle-mounted wind power generation devices have two major defects. One is that the speed of the vehicle must reach more than 30 km / h to make the wind turbine work; Only the resistance when the fan rotates can generate electricity, and the efficiency is very low

Embodiment Construction

[0016] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0017] Such as figure 1 As shown, the automatic transmission device for vehicle-mounted wind power generation includes three special-shaped differential blade fans 1, a negative pressure air duct 2, a generator 3, and a battery 5. The fan 1 is arranged inside the negative pressure air duct 2, and by rotating The shaft 4 is connected with the generator 3; the rotating shaft 4 is 3 concentric telescopic shafts, and the end of each rotating shaft 4 is connected with a fan 1, from the air inlet of the negative pressure air duct 2 to the direction of the generator, The sizes of the three fans 1 become larger in turn; the rotating shaft 4 is initially in a stretched state, and compressed according to changes in vehicle speed, so that the front and rear fans 1 are combined to rotate; the generator 3 is connected to the battery 5 through a power line connect.

Abstract

The invention relates to a vehicle-mounted wind power generation automatic speed change device which comprises a plurality of special-shaped difference blade type fans, a negative-pressure type air flue and a generator. The fans are arranged in the negative-pressure type air flue and are connected with the generator through rotating shafts. The rotating shafts are a plurality of concentric telescopic shafts. The front end of each rotating shaft is connected with the corresponding fan. The rotating shafts are in a stretching state initially and are compressed according to the change of the vehicle speed, so that the front fans and the rear fans are combined into a whole to rotate. The generator is connected with a battery through a power line. According to the vehicle-mounted wind power generation automatic speed change device, the special-shaped difference blade type fans are used so that the fans can be started to rotate to generate power when a vehicle is in a low-speed state, and the power generation efficiency is high.

Description

technical field [0001] The invention relates to a vehicle-mounted wind power generation device, and specifically discloses a vehicle-mounted wind power generation automatic speed change device. Background technique [0002] Electric vehicles have been emerging as a national strategic promotion industry. One of the main factors that plague the development of electric vehicles is the weight and volume limitations of on-board batteries. The mileage is greatly restricted, generally set at 80 kilometers, and the scarcity of charging stations , To a large extent, it is more difficult for new energy to promote automobiles. Although there are already a variety of vehicle-mounted wind power generation technologies, these vehicle-mounted wind power generation devices have two major defects. One is that the speed of the vehicle must reach more than 30 km / h to make the wind turbine work; The resistance when the fan rotates can generate electricity, and the efficiency is very low.
