Description

Technical Field

[0001] The present invention specifically relates to the technical field of wind power generation, and specifically, it is a wind power generation and power feeding device for new energy vehicles. Background Art

[0002] With the development of the automotive industry and the continuous increase in energy demand, it has become crucial to find sustainable energy solutions. Currently, vehicles mainly rely on fossil fuels for power, which not only consumes limited resources but also generates a large amount of pollutants. Therefore, developing and utilizing the renewable energy generated during vehicle driving has important practical significance.

[0003] During vehicle driving, airflows are generated in the engine compartment. These airflows are usually regarded as a wasted energy source. If these airflows can be effectively utilized to generate electricity, it will provide additional power supply for the vehicle, reduce the dependence on traditional fuels, and lower pollutant emissions.

[0004] Chinese Patent Publication No. CN 113137336 A discloses an auxiliary device for wind power generation storage and use in new energy vehicles, including a device main body. A wind turbine blade is movably installed on the outer side of the device main body. The inner side of the wind turbine blade is movably connected to a connecting spring. One end of the connecting spring away from the wind turbine blade is movably connected to a mounting plate, and one end of the mounting plate away from the connecting spring is movably connected to a shaft rod.

[0005] Under the premise of different wind directions, the wind speeds entering the engine compartment of a vehicle traveling at high speed are different.

[0006] When the vehicle is traveling at high speed, the relative airflow is mainly composed of the superposition of the relative wind generated by vehicle travel and the natural wind. If the natural wind is in the same direction as the vehicle travel (downwind), then the wind speed entering the engine compartment will increase because the airflow speed generated by the vehicle itself is superposed with the natural wind speed. At this time, the wind speed in the engine compartment is relatively high.

[0007] If the natural wind forms a certain angle with the vehicle travel direction (crosswind), the situation will be more complex. The crosswind will change the direction of the airflow entering the engine compartment, and the wind speed will also be affected. The specific wind speed depends on factors such as the intensity and angle of the crosswind and the vehicle's traveling speed.

[0008] In summary, under the premise of different wind directions, the wind speeds entering the engine compartment of a vehicle traveling at high speed are different. Therefore, we need to ensure that the wind turbine of wind power generation can collect wind power to the greatest extent.

[0009] In the above-mentioned patent for wind power generation, the wind turbine blade is fixedly arranged with the impeller, and its angle cannot be adjusted, so it is impossible to ensure that the wind turbine of wind power generation can collect wind power to the greatest extent. Summary of the Invention

[0010] The object of the present invention is to provide a wind power feeding device for new energy vehicles, which can monitor the wind speed entering the engine compartment and the output power of the wind turbine; by comparing the two sets of data, the optimal wind collection angle of the blades can be determined to ensure that the wind turbine for power generation can collect wind power to the greatest extent. To solve the technical problems proposed in the above background art.

[0011] To achieve the above object, the present invention provides the following technical solutions:

[0012] A wind power feeding device for new energy vehicles includes an adjustable power generation component, which has a plurality of blades arranged in a circular array along the impeller ring, and the blades are rotatably connected to the impeller ring, and an internal bevel gear is installed at one end where the blade root penetrates through to the impeller ring; a bevel gear ring that can be meshed and connected is provided on one side of the plurality of internal bevel gears;

[0013] A bearing is fixed inside the bevel gear ring, and an inner ring is installed in the inner ring of the bearing; a blocking disk is slidably connected to one side of the inner ring, and a slip ring is provided on the other side of the inner ring. The outer ring of the slip ring is rotatably connected to the impeller ring through a concave-convex structure, and a plurality of springs are provided on the side of the slip ring close to the bevel gear ring; an electromagnet is provided on the side of the slip ring away from the bevel gear ring.

[0014] A flow guide cover is slidably connected to one side of the impeller ring, and an end plate is fixed to the other side by bolts; a power output pipe is welded to the outside of the end plate.

[0015] As a further technical solution of the present invention, the impeller ring includes an annular shell and a chute provided inside the annular shell, and a plurality of circular holes for the blade roots to penetrate are annularly arranged on the outside of the annular shell;

[0016] An annular chute is provided on the outer ring of the annular shell connecting the flow guide cover side, and it is buckled and rotatably connected to the flow guide cover.

[0017] As a further technical solution of the present invention, a convex tube is provided in the middle of the blocking disk, and the convex tube is rotatably connected to the annular groove provided on the outside of the inner ring.

[0018] As a further technical solution of the present invention, the diameter of the blocking disk is smaller than the inner diameter of the annular shell, and a plurality of U-shaped card slots are annularly arranged around the side of the blocking disk close to the blade root;

[0019] The number of the U-shaped card slots is the same as the number of the blades, and the U-shaped card slots correspond to the blade roots one by one;

[0020] On the side of the blocking disc away from the U-shaped card slot, there are a plurality of sliders; each of the sliders is correspondingly slidably connected in the chute inside the annular shell.

[0021] As a further technical solution of the present invention, a round hole is opened on the inner side of the slip ring, and the spring is embedded in the round hole, and the length of the spring is greater than the depth of the round hole.

[0022] As a further technical solution of the present invention, the diversion cover is arranged in a conical shape, and an inner fixed disc is fixed inside the diversion cover; a fixed shaft is welded at the axial center position of the inner fixed disc; the fixed shaft is fixed on the fixed shaft.

[0023] As a further technical solution of the present invention, the axial length of the inner ring is twice the axial length of the bevel gear ring, and the outer diameter of the inner ring is smaller than the inner diameter of the slip ring.

[0024] As a further technical solution of the present invention, the fixed shaft passes through the inner ring, passes through the end disc and the power output pipe, and then is fixed to the fixed seat.

[0025] As a further technical solution of the present invention, the power output pipe and the fixed seat are installed in cooperation with a pedestal bearing, and a first bevel gear is installed in cooperation at the end of the power output pipe, and the first bevel gear is meshed and connected with a second bevel gear installed on the generator; the generator is fixed below the installation bracket.

[0027] Compared with the prior art, the beneficial effects of the present invention are:

[0028] In the present invention, each slider is correspondingly slidably connected in the chute inside the annular shell, so that the blocking disc and the impeller ring form a whole. When external air flow enters, the wind blows the blades, causing the impeller ring to rotate. The end disc and the power output pipe fixedly connected to the impeller ring rotate, and the rotation of the generator is driven through the cooperation of the first bevel gear and the second bevel gear, thus realizing the power generation of the generator, and then the wind energy can be utilized to increase the endurance of new energy vehicles;

[0029] In the present invention, when adjusting the angle of the blade, the power supply to the electromagnet is disconnected. After the electromagnet loses power, the spring inside the slip ring will eject the bevel gear ring, causing the bevel gear ring to mesh with the internal bevel gear instantaneously. The sudden meshing of the stationary bevel gear ring with the internal bevel gear will cause a certain blockage of the internal bevel gear. However, due to the continuous rotation of the impeller ring, a small range of self-rotation will occur under the meshing of the internal bevel gear and the bevel gear ring, thereby realizing a small range of angle adjustment of the blade to ensure that the wind wheel of wind power generation can collect wind power to the greatest extent.

[0030] In the present invention, the diversion cover is conically arranged, which can reduce its blockage of the wind speed, reduce the wind resistance coefficient, and has a good flow splitting effect, improving the capture of the wind body by the blade.

[0031] In the present invention, the fixed shaft passes through the inner ring, passes through the end plate and the power output pipe, and is fixed to the fixed seat. This can not only ensure that the power output pipe transmits the power generated, but also realize the fixation of the diversion cover through the fixed shaft, avoiding movement interference during use.

[0048] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0049] Please refer to Figures 1 to 12 , in the embodiments of the present invention, a new - energy vehicle wind - power generation and power - feeding device includes an adjustable power generation assembly 2. The adjustable power generation assembly 2 has a plurality of blades 22 arranged in a circular array along the impeller ring 21, and the blades 22 are rotatably connected to the impeller ring 21. And an internal bevel gear 23 is installed at one end of the blade 22 root penetrating through the impeller ring 21; on one side of the plurality of internal bevel gears 23, there is a bevel gear ring 24 that can be meshed and connected;

[0050] A bearing 25 is fixedly installed inside the inner ring of the bevel gear ring 24, and an inner ring 26 is fitted and installed inside the inner ring of the bearing 25; a blocking disc 27 is slidably connected to one side of the inner ring 26, and a sliding ring 28 is provided on the other side of the inner ring 26. The outer ring of the sliding ring 28 is rotationally connected to the impeller ring 21 through a concave-convex structure, and a plurality of springs 29 are provided on the side of the sliding ring 28 close to the bevel gear ring 24; an electromagnet 214 is provided on the side of the sliding ring 28 away from the bevel gear ring 24;

[0051] A flow guide cover 212 is slidably connected to one side of the impeller ring 21, and an end plate 211 is fixed by bolts on the other side; a power output pipe 210 is welded on the outside of the end plate 211.

[0052] As a further technical solution of the present invention, the impeller ring 21 includes an annular shell 2101 and a chute 2103 provided inside the annular shell 2101, wherein a plurality of round holes 2102 for the roots of the blades 22 to penetrate are annularly arranged on the outside of the annular shell 2101;

[0053] An annular chute is provided on the outer ring of the annular shell 2101 connecting to one side of the flow guide cover 212, and it is buckled and rotationally connected to the flow guide cover 212.

[0054] Specifically, the diameter of the blocking disc 27 is smaller than the inner diameter of the annular shell 2101, and a plurality of U-shaped card slots 272 are annularly arranged around the side of the blocking disc 27 close to the root of the blade 22.

[0055] By adopting the above technical solution, during normal operation, the electromagnet 214 is energized and sucks the inner ring 26 downward. At this time, the bevel gear ring 24 is far from the inner bevel gear 23 at the root of the blade 22. When the inner ring 26 slides to one side, it will also pull the blocking disc 27 to slide, so that the U-shaped card slot 272 provided on one side of the blocking disc 27 is engaged with the root of the blade 22, so that the blade 22 cannot rotate by itself. And a plurality of sliders 271 are provided on the side of the blocking disc 27 away from the U-shaped card slot 272; each slider 271 is correspondingly slidably connected in the chute 2103 inside the annular shell 2101, so that the blocking disc 27 and the impeller ring 21 are an integral body. When external air flow enters, the wind blows the blade 22, causing the impeller ring 21 to rotate. The end plate 211 and the power output pipe 210 fixedly connected to the impeller ring 21 rotate, and through the cooperation of the first bevel gear 3 and the second bevel gear 4, the generator 5 starts to generate electricity;

[0056] Furthermore, bolt holes for facilitating bolt fixation are provided at the upper end of the mounting bracket 1, and a wind speed sensor 8 is embedded on the side of the mounting bracket 1 facing the adjustable power generation assembly 2; the wind speed sensor 8 is electrically connected to the central controller 6; the central controller 6 is fixed on the outside of the mounting bracket 1; the central controller 6 is internally provided with a power meter, which measures the air flow velocity in the engine compartment through the wind speed sensor 8, and then measures the output power of the wind turbine 5 by using the power meter;

[0057] And the above two kinds of information are transmitted to the central controller 6, and then the data is recorded.

[0058] Example: After installing the above power generation device into the engine compartment, with the power generation assembly running under the benchmark of a wind speed of 12 m / s and a vehicle speed of 100 km / h, we calculate the power generation value:

[0059] According to the wind energy formula ; where is the wind energy power, is the air density, generally taken as 1.225 kg / m³; A is the windward area; is the wind speed.

[0060] Assume that the windward area of the wind energy power generation assembly is 1 m² (this is just an assumed value, and the actual windward area needs to be determined according to the specific size and installation position of the power generation assembly), then the wind energy power at a wind speed of 12 m / s is:

[0061]

[0062] Considering the influence of the vehicle speed:

[0063] The vehicle speed is 100 m / h, which is approximately 27.8 m / s when converted to meters per second; the vehicle running will drive the air to flow, which is equivalent to increasing a relative wind speed for the wind energy power generation assembly. However, the air flow situation generated by the vehicle running is complex, and simple superposition is not accurate. Here, for the convenience of estimation, it is assumed that the influence brought by the vehicle speed makes the effective wind speed increase by 5 m / s (this is just a very rough assumption, and the actual influence will vary due to factors such as the vehicle shape and the air flow situation in the engine compartment).

[0064] Then the effective wind speed becomes 12 + 5 = 17 m / s.

[0065] Recalculate the power:

[0066]

[0067] Estimate the power generation:

[0068] Assume that the conversion efficiency of the wind power generation component is 30% (the actual conversion efficiency may vary due to factors such as the technical level of the power generation component and the working environment), then the actual power generation is:

[0069] ;

[0070] The power generation in one hour is 1 =0.8982 kWh.

[0071] It should be emphasized that the above is only a rough estimate. The actual power generation of installing the wind power generation component in the engine compartment will be affected by many factors, such as the space limitation in the engine compartment, air flow interference, the installation angle and position of the power generation component, etc. The actual power generation may be quite different from the estimated value; the above example is only for the conversion demonstration of the power generation; through the above calculation method, the ratio of the wind speed sensed by the wind speed sensor to the power generation of the generator can be calculated; through this ratio, it can be determined whether the wind speed and the power generation are directly proportional;

[0072] When it is found that the wind speed and the power generation are not directly proportional, it can be proved that due to different angles of entry into the engine compartment, the blade 22 cannot capture the wind well; for this reason, the tilt angle of the blade 22 needs to be adjusted to ensure that the wind turbine for wind power generation can collect wind power to the greatest extent.

[0073] When adjusting the angle of the blade 22, the power supply to the electromagnet 214 is disconnected. After the electromagnet 214 loses power, the spring 29 inside the slip ring 28 will eject the bevel gear ring 24, so that the bevel gear ring 24 is instantaneously engaged with the internal bevel gear 23. The sudden engagement of the stationary bevel gear ring 24 with the internal bevel gear 23 will cause a certain blockage of the internal bevel gear 23. However, due to the continuous rotation of the impeller ring 21, a small range of self-rotation will occur under the engagement of the internal bevel gear 23 and the bevel gear ring 24, thereby realizing a small range of angle adjustment of the blade 22; after the internal bevel gear 23 and the bevel gear ring 24 are engaged for 2 - 3 s, the electromagnet 214 is powered on, and the internal bevel gear 23 and the bevel gear ring 24 are separated again under the magnetic attraction. Then, after an interval of 10 - 20 s, the wind speed sensed by the wind speed sensor and the power generation are re-measured, and through the re-analysis by the central controller, whether the power generation is directly proportional to the wind speed. The angle adjustment of the blade 22 is realized through the above adjustment method to ensure that the wind turbine for wind power generation can collect wind power to the greatest extent.

[0074] It should be noted that if the vehicle turns to another route and the wind speed and direction change, the blade 22 will rotate at a large angle until a suitable angle is found.

[0075] Please refer to Appendix Figure 10 and Figure 12, in this embodiment, a convex tube 273 is provided in the middle of the blocking disc 27, and the convex tube 273 is rotatably connected to an annular groove 261 formed on the outer side of the inner ring 26.

[0076] By adopting the above technical solution, the annular groove 261 on the outer side of the inner ring 26 is convexly arranged, so that it can be rotatably connected to the convex tube 273 and can also pull the convex tube 273 to move axially.

[0077] Specifically, the number of the U-shaped card slots 272 is the same as the number of the blades 22, and the U-shaped card slots 272 correspond to the roots of the blades 22 one by one;

[0078] The roots of the blades 22 can be clamped through the U-shaped card slots 272, and during normal operation, the blades 22 can be prevented from rotating automatically and causing the angle to change.

[0079] Please refer to the appendix Figure 10 , in this embodiment, a round hole is provided on the inner side of the slip ring 28, and the spring 29 is embedded in the round hole.

[0080] By adopting the above technical solution, the length of the spring 29 being greater than the depth of the round hole can ensure that the inner ring 26 can compress the spring 29 during axial displacement and ensure that the electromagnetic iron 214 can push out the bevel gear ring 24 after losing power.

[0081] Please refer to the appendix Figures 9 - 12 , in this embodiment, the guide cover 212 is conically arranged, and an inner fixing disc 213 is fixed inside the guide cover 212; a fixing shaft 215 is welded at the axial center position of the inner fixing disc 213; the fixing shaft 215 is fixed on the fixing shaft 215.

[0082] The conical arrangement of the guide cover 212 can reduce its blockage of the wind speed, reduce the wind resistance coefficient, and has a good flow splitting effect, improving the capture of the wind body by the blades 22.

[0083] In this embodiment, the axial length of the inner ring 26 is twice the axial length of the bevel gear ring 24, and the outer diameter of the inner ring 26 is smaller than the inner diameter of the slip ring 28.

[0084] By adopting the above technical solution, when the electromagnetic iron 214 is attracted, it can ensure the smooth sliding of the inner ring 26 and ensure that the bevel gear ring 24 can abut against the spring 29.

[0085] Please refer to the appendix Figures 1 - 9, in this embodiment, the power output pipe 210 is installed in cooperation with the fixed seat 7 through a pedestal bearing, and a first bevel gear 3 is installed at the end of the power output pipe 210 in cooperation. The first bevel gear 3 is meshed and connected with a second bevel gear 4 installed on the generator 5; the generator 5 is fixed below the installation bracket 1.

[0086] By adopting the above technical solution, the fixed shaft 215 passes through the inner ring 26, passes through the end plate 211 and the power output pipe 210, and then is fixed to the fixed seat 7. In this way, it can not only ensure that the power output pipe 210 transmits the power for power generation, but also realize the fixation of the diversion cover 212 through the fixed shaft 215, avoiding movement interference during use.

[0087] The working principle is:

[0088] During normal operation, the electromagnet 214 is energized and attracts the inner ring 26 downward. At this time, the bevel gear ring 24 is away from the inner bevel gear 23 at the root of the blade 22. When the inner ring 26 slides to one side, it will also pull the blocking disc 27 to slide, so that the U-shaped card slot 272 opened on one side of the blocking disc 27 is engaged with the root of the blade 22, so that the blade 22 cannot rotate self. And there are a plurality of sliders 271 on the side of the blocking disc 27 away from the U-shaped card slot 272; each of the sliders 271 is correspondingly slidably connected in the chute 2103 inside the annular shell 2101, so that the blocking disc 27 and the impeller ring 21 are an integral body. When external air flow enters, the wind blows the blade 22, causing the impeller ring 21 to rotate. The end plate 211 and the power output pipe 210 fixedly connected to the impeller ring 21 rotate, and drive the generator 5 to start generating electricity through the cooperation of the first bevel gear 3 and the second bevel gear 4;

[0089] When it is found that the wind speed and the power generation amount are not proportional, it can be proved that the angles of entry into the engine compartment are different, and the blade 22 cannot capture the wind well; for this reason, the inclination angle of the blade 22 needs to be adjusted to ensure that the wind turbine for wind power generation can collect wind power to the greatest extent.

[0090] When adjusting the angle of the blade 22, the power supply to the electromagnet 214 is disconnected. After the electromagnet 214 loses power, the spring 29 inside the slip ring 28 will eject the bevel gear ring 24, causing the bevel gear ring 24 to mesh with the internal bevel gear 23 instantaneously. The sudden meshing of the stationary bevel gear ring 24 with the internal bevel gear 23 will cause a certain blockage of the internal bevel gear 23. However, due to the continuous rotation of the impeller ring 21, a small range of self-rotation will occur under the meshing of the internal bevel gear 23 and the bevel gear ring 24, thereby realizing a small range of angle adjustment of the blade 22. After the internal bevel gear 23 and the bevel gear ring 24 have meshed for 2 - 3 s, the electromagnet 214 is powered on, and the internal bevel gear 23 and the bevel gear ring 24 are separated again under the attraction of the magnetic force. Then, after an interval of 10 - 20 s, the wind speed sensed by the wind speed sensor and the power generation are re-measured, and through re-analysis by the central controller, whether the power generation is proportional to the wind speed. The angle of the blade 22 is adjusted by the above adjustment method to ensure that the wind turbine of the wind power generation can collect wind power to the greatest extent.

Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive.
