According to statistics from the International Energy Agency, from 2001 to 2003, oil consumption for transportation alone accounted for about 57% of the world's total, and it is expected that by 2010, its consumption will increase by more than 60%.

Faced with the problems and trends of oil shortage and environmental pollution, people have proposed to carry out a technological revolution on the vehicles with the largest energy consumption, and began to search for them. In the future, they can be widely used on vehicles, which is convenient and cheap. For new energy sources and systems that do not pollute or less pollute the environment, almost all countries have realized that the future use of transportation energy will inevitably require transformation.

As people continue to pay attention to transportation products such as electric vehicles that are energy-saving and environmentally friendly, batteries have become a bottleneck on the road to the development of electric transportation products. In response to the above problems, industry professionals have proposed a solution, as shown in Patent Document 1, which is an electric vehicle. It has an automatic power generation charging structure. The electric vehicle includes a battery, a driving device, a start switch, a wheel body, and an axle. The drive device is used to drive the wheel shaft to rotate, the battery is used to provide the power required by the drive device, and the start switch is used to Control the start and stop state of the driving device; the automatic charging structure includes: a rotating impeller, which is arranged at a predetermined position of the electric vehicle by a shaft pivot; a first generator, which includes a shaft, and one end of the shaft is driven by a first transmission The component is connected to the shaft of the rotating impeller for transmission, and the electric output end of the first generator is connected to the battery of the electric vehicle; the second generator includes a rotating shaft, and the rotating shaft is connected with the The wheel shaft is connected to drive, and the electric output end of the second generator is connected to the battery of the electric vehicle; The coupling device is arranged between the second generator's shaft and the second transmission component, so as to switch the connection transmission or release of the second shaft and the second transmission component; the actuation of the clutch device is activated by the electric vehicle. Controlled by the switch, when the start switch is in the off mode, the clutch device is in a state of connecting the rotating shaft and the second transmission component.

Patent Document 1: Domestic Patent Publication No. M306277 "Automatic Power Generation Charging Structure of Electric Vehicles".

<p>The aforementioned Patent Document 1 has the following problems:</p><p>1. Among them, the combination of the clutch device and the second generator is used for power generation, which will cause a large abrasion and reduce the overall recovered power, which can only reach up to 70% of the recovered power, which is difficult to increase, and because it increases The two sets of mechanical devices, the second transmission component and the second generator, will increase the overall weight, so the burden on the driving device will be greater, and it will consume more power, so the driving time will only be shorter and shorter, and will not change. long.</p><p>In view of this, how to make it possible to generate electricity without adding a transmission component and a generator to extend the driving time has become one of the purposes of the new type.</p><p>2. The first generator used in the aforementioned wind power generation, combined with a rotating impeller, etc., is a larger wind power generation mechanism that requires a larger amount of wind to generate electricity. Therefore, when used on a lower-speed electric vehicle, its power generation efficiency Poor, on the contrary, is the burden of electric vehicles, and the overall practicability is not high for electric vehicles mainly for urban driving.</p><p>In view of this, how to improve the power generation efficiency of the wind power generation mechanism and apply it to the use environment of electric vehicles has become the second purpose of the new type to be improved.</p><p>3. For general electric vehicles, if you want to cooperate with the setting of wind turbines, because the wind speed is low when traveling in the city, the current best large-scale wind turbines can generate electricity at a wind speed of 10.0 (m / s). At 62%, wind speed of 12.5 (m / s), power generation efficiency can reach 100%, wind speed of 20.0 (m / s), power generation efficiency can reach 320%; and at a speed of 90 (km / hr), The wind speed is 25 (m / s), but today's electric vehicles have a maximum speed of 50 (km / hr) in the urban area, a wind speed of 14 (m / s), and the power generation efficiency can reach 86%. The overall power generation It is not large. For electric vehicles, although the ratio of the distance that can be traveled to the weight of energy will increase, the power density of the battery will decrease. The increase in the distance traveled by electric vehicles is not obvious, and the industrial utility is not large.</p><p>In view of this, how to increase the travelable distance and energy weight of electric vehicles, increase the power density of storage batteries, and make up for the shortcomings of low efficiency of wind power generators in urban areas has become the third purpose of this new type of improvement. .</p>

The following is a detailed description based on the embodiment shown in the figure: as shown in FIG. 1 is a schematic diagram of the implementation of the new model, and as shown in FIG. 2 is a block diagram of the new model.

The figure reveals that it is an electric vehicle with a power generation auxiliary module, which is characterized by comprising: an electric vehicle (1), the electric vehicle (1) is provided with at least one motor capable of providing power to the electric vehicle (1) (11), and at least one battery (12) electrically connected to the motor (11) and capable of supplying power thereto; at least one small wind power device (2) provided inside or / and outside the electric vehicle (1), the The small wind power generation device (2) is an air collecting pipe (21) which is provided at the front end of the electric vehicle (1) by an opening (211) and can introduce wind therein, and at least one axis is arranged in the air collecting pipe (21). A fan (22) and a generator (23) connected to the corresponding fan (22) and electrically connected to the battery (12); and a fan (22) provided between the motor (11) and the battery (12). A controller (3) for controlling the operation of the motor (11) or inverter power generation. The controller (3) and the battery (12) are connected by a first electric wire (31) for energization and a single-directional charging The second wire (32) of the device (4) is electrically connected.

Among them, the motor (11) that drives the electric vehicle (1) is directly used as a generator. When the electric vehicle (1) decelerates, brakes and goes downhill, and the motor (11) does not consume electricity, its generated power is picked up. Charge the battery to recover the inertial kinetic energy during deceleration, braking, and potential energy when going downhill, and convert it into electrical energy to allow the electric vehicle (1) to run longer and extend the service life of the electric vehicle (1).

Secondly, the electric vehicle (1) is used to generate retrograde airflow and air pressure difference to drive the small wind power generation device (2) installed inside or outside the electric vehicle (1) to work, and convert the mechanical energy generated by it into electrical energy. And stored it, through the aforementioned motor (11) power generation method, and the small wind power generation device (2) in cooperation, to achieve the effect of increasing the distance between the distance and the weight of energy, and because the small wind power generation device (2) The installation is equivalent to increasing the capacity of the battery (12), so the battery (12) used in the new model can be lighter; there is an absolute relationship between the endurance of the electric vehicle (1) and the energy density of the battery. Currently, lead-acid batteries are used. For an energy density of about 40 Wh / kg, an electric vehicle (1) equipped with a 300 kg battery can travel about 80 km, and the ratio of the distance that can be traveled to the weight of the energy is 0.27. After using this model, as long as the electric vehicle is equipped with a 200 kg battery (1) It can drive more than 100km (depending on the weather, the greater the wind, the farther), the ratio of the distance that can be traveled to the weight of energy is 2 or more. On the other hand, although the power density of the battery is affected by its structure, For low, the weight power density of general lead-acid batteries is about 150W / kg, but through continuous charging, it will be replenished when it is used up, which is equivalent to increasing the capacity of the battery (12), which can increase the power per 1Kg, so the power of the battery The density will also be relatively increased.

In addition, the small-scale wind power generation device (2) used in the new model has a limit efficiency of aerodynamic conversion of about 45% to 55%, and can generate electricity in a light wind state, which is different from the ability to generate electricity under strong wind. The traditional large-scale wind power generation device can achieve the effect of continuous power generation, and although there are multiple generators therein, although the power is small, multiple power generators generate power at the same time, and the power is also considerable.

In addition, because the battery (12) is continuously charged when the electric vehicle (1) is running, it can also reduce the burden on consumers, so that consumers do not have to recharge from time to time, which is environmentally friendly and saves money.

In the above, the battery (12) is further electrically connected to the generator (23) by a fourth wire (34), and a battery unit (12) and the generator (23) is further provided with a unit capable of preventing current recharging. The guide charger (4B); the battery (12) is further electrically connected with at least one solar cell (5) on the surface of the electric vehicle (1) by a fifth wire (35), and the battery (12) and the solar cell (5), there is also a single-oriented charger (4C) that can avoid current recharging; and the first wire (31) between the controller (3) and the battery (12) is also provided with a Speed controller (6).

Among them, the use of the single-oriented charger (4B) can allow the electricity of the generator (23) to be smoothly charged into the battery (12) without backflow, which causes damage to the generator (23) and can effectively To prevent damage to the battery (12).

Secondly, in addition to this type of power generation method of small wind power generation devices (2), electric vehicles (1) are mostly used in urban areas, and the speed limit in urban areas is 40-50Km / Hr. The reduction is slightly insufficient for some electric vehicles (1). Therefore, according to the different needs of the vehicles used, the new model can also be combined with a solar cell (5) to combine wind, solar, and recovered electrical energy to combine these three types of charging. Methods to complement their shortcomings in order to achieve the goals of increasing driving time and improving operating efficiency, and through this setting, the new driving distance can be extended from short-distance urban driving to extended long-distance driving, allowing electric The utility of the car is improved.

Furthermore, the use of the speed controller (6) allows the user to flexibly control the speed of the vehicle.

In the above, the motor (11) and the generator (23) are permanent magnet DC motors, which can be effectively used as generators and motors, and their structures and principles are generally known technologies, so This will not be explained in detail.

In the above, the electric vehicle (1) is one of the following: a skateboard-type light electric vehicle, a three-wheeled electric vehicle, a railcar, an electric bicycle, an electric vehicle, and an electric vehicle.

Among them, the new model is applicable to different electric vehicles (1), which has high applicability, can be installed on the aforementioned electric devices, and can effectively solve the problem that current electric vehicles are not high in overall efficiency and cannot be used universally.

In the above, the storage battery (12) is one of the following: a lead-acid battery, a nickel-cadmium battery, a nickel-iron battery, a nickel-zinc battery, a new bromine battery, a sodium-sulfur battery, a sodium-nickel-chloride battery, a lithium battery, or a lithium-ion battery , Ni-MH batteries, zinc-air batteries, aluminum-air batteries.

Among them, according to different electric vehicles (1), according to their overall weight, the most suitable battery (12) can be used to exert the functions and effects of the new model.

In the above, the fan (22) is a fan with small air resistance and high torque; and the type of the fan (22) is one of the following: a turbo fan, a spiral fan, an axial fan, a cross flow fan .

Among them, different fans (22) are used to comply with the electric vehicle (1) used to obtain the highest airflow efficiency and produce the best power generation effect, so that the small wind power generation device (2) can exert its due effect. To increase practicality.

Secondly, although different fans (22) are used, they must meet the benchmark of low air resistance and high torque to exert the best power generation efficiency without affecting the driving speed and safety of the vehicle.

In the above, the opening (211) is further provided with a filter screen (25) capable of blocking debris; and at the rear end of the filter screen (25), at least one air deflector plate capable of controlling the amount of air volume ( twenty four).

Among them, a filter (25) is arranged to prevent the internal fan (22), the generator (23) and the deflector (24) from being damaged by the impact of foreign objects or being affected by the accumulation of dust. The overall power generation efficiency is reduced.

Secondly, through the use of the deflector (24), when the electric vehicle (1) is driving at low speed, the wind concentrated by the air collecting pipe (21) can be concentrated again, so that the subsequent generator (23) can Stable power generation.

In addition, the deflector (24) can also close the wind collecting pipe (21) when the new model is stopped to isolate the influence of environmental wind, so that the small wind power generator (2) will not run, so as to extend the generator ( 23) Service life.

In the above, the driving mode of the electric vehicle (1) is one of the following: a rear-wheel drive type and an independent drive type of each wheel.

Among them, the above-mentioned driving method can provide a larger installation space for the small wind power generation device (2) to generate the best operating efficiency.

In the above, the controller (3) and the motor (11) are electrically connected by a third wire (33).

Among them, because the motor (11) is used for driving and power generation, simple wiring can effectively reduce unnecessary power loss and increase the overall efficiency.

In the above, the air collecting pipe (21) is one of the following: a wide to narrow pipe body, a front and rear pipe body having the same width.

Among them, according to the different installation locations, different air collecting pipes (21) are used, and the air deflectors (24) in them are used to effectively collect wind to achieve a certain operating efficiency and enable small wind power generation devices (2). The scope of application is more extensive.

As shown in FIG. 3 and FIG. 4, it is a schematic diagram of the implementation of the novel circuit, and as shown in FIG. 5 and FIG. 6, it is a schematic diagram of the implementation and operation of the novel embodiment.

The figure reveals that when the electric vehicle (1) is started, the controller (3) passes the first electric wire (31) to let the electricity of the battery (12) pass through the third electric wire (33) and input into the motor (11). In order to drive the electric vehicle (1) to move, at the same time, due to the movement of the electric vehicle (1), the moving electric vehicle (1) will generate air pressure differences in different parts of the locomotive due to air resistance. (1) There will be air flow around the body of the vehicle. Therefore, the natural wind is used to collect the wind by the air collecting tube (21), and the air deflector (24) inside the air collecting tube (21) Different pressure differences are generated at the outlet, naturally compressing the density of the wind, constantly holding the wind, and entering the wind collecting tube (21). A large amount of wind constantly squeezes the density of the wind, so that the wind collecting tube (21) is generated inside and outside. The pressure difference draws the air flow outside the pipe. The pressure forces the flow velocity in the air collecting pipe (21) to increase. Wind energy drives the fan (22), which drives the fan (22) to generate a centrifugal circle rotation, and converts wind energy into kinetic energy. The rotary kinetic energy converter, that is, the generator (23) generates electricity, which is input into the battery (12) through a single-oriented charger (4B) to compensate A battery (12) power consumption (3, 5).

The timing of its power generation is as follows: [A] Taxiing downhill; [B] Red light ahead, taxiing to stop; [C] Turning to brake; [D] Speeding to taxi and decelerating; [E] To be ahead [F] Poor traffic conditions during vehicle keeping distance, traffic jam.

In other words, when the user releases the electric throttle (throttle) while the vehicle is running, the controller (3) allows the function of the motor (11) to be converted from driving to electricity generation, and the electricity is transferred to the battery (12). in.

At the same time, when the electric vehicle (1) is at a low speed, and if it is during the daytime, it can also pass through the solar battery (5), via the fifth electric wire (35) and the single guide charger (4C). The electricity is input into the battery (12) to supplement the power consumption of the battery (12) and become an additional power source (see Figures 3 and 5).

In addition, when the electric vehicle (1) is decelerating, braking and downhill, the controller (3) is used to prevent the motor (11) from eating electricity, and the motor (11) is used as a generator instead of the inverter (11). The electricity that generates the rebound power is passed through the third wire (33), the controller (3), the second wire (32), and the single-oriented charger (4B) to charge the battery (12) to recover the deceleration and braking. The inertial kinetic energy at the time and potential energy when downhill are converted into electrical energy. At the same time, the small wind power device (2) and the solar battery (5) are still being charged (see Figures 4 and 6). The overall power consumption is regarded as 100%, and the recovered power is generally 60 to 70%. With the assistance of the aforementioned two power generation devices, it can effectively supplement the lost part. Although it cannot achieve 100% recovery, it can continue to Approaching 100% is conducive to extending the driving time of the electric vehicle (1) and improving the overall operating efficiency.

It can be known from the above that in the new model, through the cooperation of the motor (11), the small wind power generation device (2) and the solar cell (5), the overall power consumption and charging capacity ratio can be maintained at a stable level. Let the electric vehicle (1) run longer, extend the service life of the electric vehicle (1), make the battery (12) truly have a longer and more economical service life, and truly welcome the bright development of the industrialization of electric vehicles Compared with today's conventional electric vehicles, this road is more practical, functional, and industrially usable.

The structure, characteristics, and effects of the new model have been described in detail based on the embodiment shown in the figure. Because it meets the novel and progressive requirements, a new patent application has been filed in accordance with the law; however, the above are only the best implementation of this creation. For example, but this creation does not limit the scope of implementation as shown in the drawing, so any modification that is consistent with the purpose of this creation should be included in the scope of this creation patent as long as it is within the scope of equality.
