Description

Technical Field

[0001] This invention is a wind energy recovery system for new energy vehicles, belonging to the field of new energy vehicle technology. Background Technology

[0002] With the rapid development of the new energy vehicle industry, insufficient driving range has become one of the core issues restricting its widespread adoption. Currently, new energy vehicles mainly rely on charging stations for energy replenishment. However, during driving, the front of the vehicle is subjected to a large amount of airflow, which is often wasted and may even become a drag on the vehicle.

[0003] Currently, when people mention utilizing wind energy, they still think in the traditional way—converting wind energy into electricity, giving people the feeling that wind and electricity are inseparable.

[0004] Currently, wind farms widely use three-bladed wind power generation devices, such as the vertical-axis three-dimensional wind turbine disclosed in patent CN1399068. These wind power devices generally lack dedicated airflow collection devices, leaving the blades directly exposed to the natural environment, resulting in low wind energy utilization. Some wind power generation devices are equipped with dedicated airflow collection devices; however, these pose safety risks when typhoons or super winds suddenly strike, and their airflow collection efficiency is low. They lack targeted airflow guidance structures and cannot effectively gather airflow during vehicle operation. When the vehicle speed is too high, causing excessive airflow pressure, it can easily damage the turbine blades and affect system stability. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the purpose of this invention is to provide a wind energy recovery system for new energy vehicles.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution: A wind energy recovery system for a new energy vehicle includes a vehicle body, a wind energy recovery mechanism installed at the front air intake grille of the vehicle body, and a management system for energy conversion. The wind energy recovery mechanism includes a collection hood fixed to the air intake grille, a conical hood fixedly connected to one side of the air outlet of the collection hood, a transition channel fixedly connected to the narrow end of the conical hood, an airflow channel fixedly connected to the end of the transition channel away from the conical hood, a spiral fan blade rotatably installed in the airflow channel via a bearing seat, and a high-speed generator fixedly connected to the power output end of the spiral fan blade via a coupling. The top center of the transition channel is provided with a drainage mechanism for releasing excessive airflow pressure.

[0007] Preferably, the drainage mechanism includes a drainage tube that is vertically fixed through the top of the transition channel. The lower inner side of the drainage tube is provided with a horizontally arranged ring. The top of the ring is surrounded by a plurality of evenly distributed adjusting plates. The adjusting plates are combined to form a sealing structure for opening and closing the drainage tube.

[0008] Preferably, one corner of the adjusting plate is movably connected to the ring via a rotating shaft, and a connecting ring is fixedly installed inside the drainage tube and above the adjusting plate.

[0009] Preferably, a sliding shaft is fixedly connected to the top center of the adjusting plate, the sliding shaft movably passes through the connecting ring, and a hydraulic cylinder is movably connected to the top of the sliding shaft via a ball joint.

[0010] Preferably, the end of the hydraulic cylinder away from the sliding shaft is movably connected to the upper surface of the connecting ring via a pin.

[0011] Preferably, the connecting ring has an arc-shaped travel hole for the sliding shaft to slide radially, and the number of the travel holes is consistent with and corresponds one-to-one with the adjusting plate.

[0012] Preferably, the edges of adjacent adjustment pieces are fitted together, and the adjustment pieces are made of a lightweight alloy material.

[0013] Preferably, the output terminal of the high-speed generator is connected to a rectifier and a battery via wires, the battery is electrically connected to the on-board power supply system of the new energy vehicle, and the controller is integrated into the on-board control system.

[0014] Preferably, the inlet end of the collection hood is provided with a protective net, the inner wall of the conical hood is provided with a smooth and wear-resistant coating, the blades of the spiral fan are designed with a streamlined shape, and the outlet end of the airflow channel is provided with a sound-absorbing structure.

[0015] Preferably, the management system includes a wind pressure sensor and a controller. The wind pressure sensor is installed in the transition channel, and the controller is electrically connected to both the wind pressure sensor and the hydraulic cylinder. The controller has a built-in pressure threshold parameter. When the wind pressure sensor detects that the air pressure in the transition channel exceeds the threshold, the controller controls the hydraulic cylinder to extend or retract.

[0016] The beneficial effects of this invention are: By combining the collection hood and the conical hood, the system effectively gathers and accelerates the airflow, significantly increasing the rotational speed of the turbine blades and improving energy conversion efficiency compared to traditional systems. Through the coordination of the airflow diversion mechanism and management system, the airflow pressure can be monitored in real time. When the vehicle speed is too high, such as high-speed driving causing the pressure to exceed the threshold, the diversion tube automatically opens to release the pressure, preventing turbine blade overload damage and ensuring long-term stable operation of the system. The wear-resistant coating of the conical hood reduces airflow resistance and wear, and the sound-absorbing structure of the airflow channel reduces operating noise. The overall structural design balances practicality and durability. The system can convert wind energy during driving into electrical energy to supplement the vehicle's power supply system. Under normal driving conditions, it can improve the driving range of new energy vehicles, and is especially suitable for long-distance high-speed driving scenarios. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figure 1-8 The present invention provides a technical solution for a wind energy recovery system for new energy vehicles, including a vehicle body 1, a wind energy recovery mechanism installed at the front air intake grille of the vehicle body 1, and a management system for energy conversion; The wind energy recovery mechanism includes a collection hood 2 fixed to the air intake grille, a conical hood 3 fixedly connected to one side of the air outlet of the collection hood 2, a transition channel 4 fixedly connected to the narrow end of the conical hood 3, an airflow channel 5 fixedly connected to the end of the transition channel 4 away from the conical hood 3, a spiral fan blade 6 rotatably installed in the airflow channel 5 through a bearing seat, and a high-speed generator 7 fixedly connected to the power output end of the spiral fan blade 6 through a coupling. The top center of the transition channel 4 is provided with a drainage mechanism for releasing excessive airflow pressure.

[0022] When the vehicle is in motion, the airflow at the front end enters the collection shroud 2 fixed to the air intake grille of the vehicle body 1 under the action of pressure difference. The trumpet-shaped structure of the collection shroud 2 expands the airflow capture range, while the protective net at the inlet end filters impurities in the airflow to avoid damage to internal components. After the airflow is gathered by the collection shroud 2, it flows into the conical shroud 3 fixedly connected to it. The gradual structure from the large opening to the narrow opening of the conical shroud 3 significantly increases the airflow velocity, and the smooth and wear-resistant coating on the inner wall reduces airflow resistance and energy loss, providing sufficient power for the subsequent turbine drive. The accelerated airflow is smoothly introduced into the airflow channel 5 through the transition channel 4 at the narrow opening of the conical shroud 3, completing the collection and pretreatment of the airflow.

[0023] Please see Figure 1-8 The drainage mechanism includes a drainage tube 8 that is vertically fixed through the top of the transition channel 4. A horizontally arranged ring 9 is provided on the inner side of the lower end of the drainage tube 8. A number of evenly distributed adjusting plates 10 are arranged around the top of the ring 9. The adjusting plates 10 are combined to form a sealing structure for opening and closing the drainage tube 8.

[0024] One side corner of the adjusting plate 10 is movably connected to the ring 9 via a rotating shaft 11, and a connecting ring 12 is fixedly installed inside the drainage tube 8 and above the adjusting plate 10.

[0025] The top center of the adjusting plate 10 is fixedly connected to a sliding shaft 13, which movably passes through the connecting ring 12. The top of the sliding shaft 13 is movably connected to a hydraulic cylinder 14 via a ball joint.

[0026] The end of the hydraulic cylinder 14 away from the sliding shaft 13 is movably connected to the upper surface of the connecting ring 12 via a pin 15.

[0027] The connecting ring 12 has an arc-shaped travel hole 16 for the sliding shaft 13 to slide radially. The number of travel holes 16 is the same as that of the adjusting plate 10 and they correspond one-to-one.

[0028] The edges of adjacent adjustment pieces 10 are fitted together, and the adjustment pieces 10 are made of a lightweight alloy material.

[0029] The wind pressure sensor 17 installed in the transition channel 4 detects the airflow pressure in the channel in real time and continuously transmits the pressure signal to the controller 18 integrated into the vehicle control system. The controller 18 has a built-in preset pressure threshold. When the detected air pressure does not exceed the threshold, the regulating plate 10 of the diversion mechanism remains closed to ensure that all airflow is used to drive the spiral fan blade 6, thus ensuring energy conversion efficiency. When the vehicle travels at high speed, such as ≥100km / h, causing the airflow pressure to exceed the threshold, the controller 18 sends a telescopic command to the hydraulic cylinder 14. The hydraulic cylinder 14 is movably connected to the connecting ring 12 via a pin 15. When its piston rod telescopically extends or retracts, it drives the sliding shaft 13, which is connected to it via a ball joint, to move along the arc of the connecting ring 12. The sliding hole 16 slides radially, and the sliding shaft 13 is fixedly connected to the top center of the adjusting plate 10. The adjusting plate 10 is movably connected to the ring 9 through the rotating shaft 11. The sliding of the sliding shaft 13 drives the adjusting plate 10 to rotate around the rotating shaft 11, causing the edges of adjacent adjusting plates 10 to separate, opening the diversion tube 8. Part of the airflow is discharged through the diversion tube 8, and the air pressure in the transition channel 4 drops to the safe threshold. When the wind pressure sensor 17 detects that the air pressure is lower than the threshold, the controller 18 controls the hydraulic cylinder 14 to extend and retract in the opposite direction, and the adjusting plate 10 resets and closes the diversion tube 8, restoring the full power energy recovery state. The controller 18 monitors the operating status of the high-speed generator 7 in real time, dynamically optimizes the energy conversion parameters, and ensures the balance between power generation efficiency and system stability.

[0030] Please see Figure 1-8The output end of the high-speed generator 7 is connected to a rectifier and a battery via wires. The battery is electrically connected to the on-board power supply system of the new energy vehicle. The controller 18 is integrated into the on-board control system. The inlet end of the collection cover 2 is provided with a protective net. The inner wall of the conical cover 3 is provided with a smooth and wear-resistant coating. The blades of the spiral fan 6 adopt a streamlined design. The outlet end of the airflow channel 5 is provided with a noise reduction structure. The management system includes a wind pressure sensor 17 and a controller 18. The wind pressure sensor 17 is installed in the transition channel 4. The controller 18 is electrically connected to the wind pressure sensor 17 and the hydraulic cylinder 14 respectively. The controller 18 has a built-in pressure threshold parameter. When the wind pressure sensor 17 detects that the air pressure in the transition channel 4 exceeds the threshold, the controller 18 controls the hydraulic cylinder 14 to extend or retract.

[0031] When in use, as the vehicle is in motion, the airflow at the front end enters the collection hood 2 fixed to the air intake grille of the vehicle body 1 under the action of pressure difference. The trumpet-shaped structure of the collection hood 2 expands the airflow capture range, while the protective net at the inlet end filters impurities in the airflow to avoid damage to internal components. After the airflow is gathered by the collection hood 2, it flows into the conical hood 3 fixedly connected to it. The gradual structure from the large opening to the narrow opening of the conical hood 3 significantly increases the airflow velocity, and the smooth wear-resistant coating on the inner wall reduces airflow resistance and energy loss, providing sufficient power for the subsequent turbine drive. The accelerated airflow is smoothly introduced into the airflow channel 5 through the transition channel 4 at the narrow opening of the conical hood 3, completing the collection and pretreatment of the airflow. A high-speed airflow impacts a spiral fan blade 6 mounted rotatably within an airflow channel 5 via a bearing housing. The streamlined blades of the spiral fan blade 6 efficiently capture the kinetic energy of the airflow, driving the blades to rotate at high speed. The power output end of the spiral fan blade 6 is fixedly connected to a high-speed generator 7 via a coupling. The mechanical rotational kinetic energy of the turbine is directly transferred to the high-speed generator 7, driving the generator to generate electricity through electromagnetic induction, thus converting wind energy into electrical energy. The AC power output from the high-speed generator 7 is transmitted to a rectifier via wires, converted into DC power by the rectifier, and stored in a battery electrically connected to the vehicle's power supply system. This power supplies the vehicle's electrical equipment or assists in driving the vehicle, replenishing its range. The wind pressure sensor 17 installed in the transition channel 4 detects the airflow pressure in the channel in real time and continuously transmits the pressure signal to the controller 18 integrated into the vehicle control system. The controller 18 has a built-in preset pressure threshold. When the detected air pressure does not exceed the threshold, the regulating plate 10 of the diversion mechanism remains closed to ensure that all airflow is used to drive the spiral fan blade 6, thus ensuring energy conversion efficiency. When the vehicle travels at high speed, such as ≥100km / h, causing the airflow pressure to exceed the threshold, the controller 18 sends a telescopic command to the hydraulic cylinder 14. The hydraulic cylinder 14 is movably connected to the connecting ring 12 via a pin 15. When its piston rod telescopically extends or retracts, it drives the sliding shaft 13, which is connected to it via a ball joint, to move along the arc of the connecting ring 12. The sliding hole 16 slides radially, and the sliding shaft 13 is fixedly connected to the top center of the adjusting plate 10. The adjusting plate 10 is movably connected to the ring 9 through the rotating shaft 11. The sliding of the sliding shaft 13 drives the adjusting plate 10 to rotate around the rotating shaft 11, causing the edges of adjacent adjusting plates 10 to separate, opening the diversion tube 8. Part of the airflow is discharged through the diversion tube 8, and the air pressure in the transition channel 4 drops to the safe threshold. When the wind pressure sensor 17 detects that the air pressure is lower than the threshold, the controller 18 controls the hydraulic cylinder 14 to extend and retract in the opposite direction, and the adjusting plate 10 resets and closes the diversion tube 8, restoring the full power energy recovery state. The controller 18 monitors the operating status of the high-speed generator 7 in real time, dynamically optimizes the energy conversion parameters, and ensures the balance between power generation efficiency and system stability.

[0032] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
