Description

Technical Field

[0001] The present invention belongs to the field of new energy vehicle power generation and range extension, and specifically relates to a micro-wind power generation device with a closable automobile air deflector duct. Background Art

[0002] As the popularity of new energy vehicles increases, the amount of electricity consumed by cars increases year by year. Existing car energy recovery is diverse, but the systems are diverse and complex. Electric cars and hybrid electric cars are supported by many countries and people due to their advantages such as low pollution and low operating costs. However, the current technical problems of power batteries require multiple power batteries to form a power battery pack, so the weight of the power battery is 1 to 2 tons. At the same time, due to the limited power stored in the power battery, it will be used up quickly, so it cannot run long distances or high speeds. And after driving a distance, its speed will decrease; and the service life of the power battery is limited, so the on-board power battery must be replaced after running to a limited distance or limited time, and the number of charging times, which increases the cost of electric vehicles and limits the development of electric vehicles. Hybrid electric vehicles also have the above shortcomings of pure electric vehicles, and they need to be refueled regularly, so they are also subject to various restrictions.

[0003] Chinese utility model patent CN215705703U discloses a stable electric vehicle wind power range extender, which performs secondary power generation by installing a wind power range extender on the top of the vehicle. However, the device does not take into account that the addition of the range extender also increases the wind resistance of the vehicle, which is not conducive to high-speed driving of the vehicle.

[0004] Therefore, how to provide a closable micro-wind power generation device with a car air deflector duct without increasing wind resistance has become an issue that technical personnel in this field need to consider. Summary of the invention

[0005] In view of the problems existing in the above-mentioned prior art, the present invention discloses a closable micro-wind power generation device with a car air deflector duct. The present invention fully utilizes the airflow passing through the vehicle's air intake duct, and uses wind power to drive the turbine power generation mechanism to generate electricity, thereby improving the cruising range of new energy vehicles. The device can also be closed when the vehicle accelerates to avoid increasing the vehicle's wind resistance.

[0006] Specifically, this application discloses the following technical solutions:

[0007] A closable micro-wind power generation device with an automobile air deflector duct comprises an air collecting hood, an air intake duct, a turbine power generation mechanism and an air outlet passage. The air collecting hood is installed in the air deflector at the top of the vehicle cab. The air collecting hood is trumpet-shaped.

The air intake duct and the turbine power generation mechanism are arranged on the top of the vehicle cab. The air collecting hood, the air intake duct, the turbine power generation mechanism and the air outlet passage are sequentially connected.

[0008] Furthermore, the electric opening and closing mechanism includes a frame, louvers, a driving shaft, a driven shaft, a driving plate and a driving motor. A sealing gasket is arranged between the frame and the air inlet of the wind condenser hood. The driving shaft and the driven shaft are both rotatably arranged in the frame. The driven shaft is arranged on both sides of the driving shaft. The louvers are fixedly installed on the driving shaft and the driven shaft. The driving shaft and the driven shaft are both equipped with gears. The driving plate is slidably limited in the frame. A rack is arranged on one side of the driving plate corresponding to the gear, and the rack is meshed with the gear. The driving motor is arranged on one side of the frame, and the output shaft of the driving motor is fixedly connected to the driving shaft.

[0009] Furthermore, it also includes a filter screen, which is arranged at the front end of the frame and is used for filtering air.

[0010] Furthermore, the turbine power generation mechanism includes a silencer chamber, a mounting bracket, turbine blades and a permanent magnet generator. The mounting bracket is cross-shaped and installed in the silencer chamber. The front end of the mounting bracket is streamlined. The permanent magnet generator is arranged inside the mounting bracket, and the turbine blades are installed on the rotor of the permanent magnet generator.

[0011] Furthermore, the number of blades of the turbine fan blade is 6-8.

[0012] Furthermore, the surface of the silencing chamber is provided with a silencing and heat-insulating layer and an anti-corrosion coating in sequence from the inside to the outside.

[0013] Furthermore, it also includes an air circulation pipeline, which is connected to one side of the air outlet duct. The manifold of the air circulation pipeline extends into the cab, and the manifold is connected to the air outlet of the air conditioner external circulation.

[0014] Furthermore, it also includes a voltage stabilizing module, which is electrically connected to the permanent magnet generator.

[0015] The beneficial effects of the present invention are as follows: through the arrangement of the wind collecting hood and the turbine power generation mechanism, the present invention can allow the airflow to pass through the trumpet-shaped wind collecting hood when the vehicle slows down, goes downhill or stops at the wind outlet, and utilizes the Venturi effect to increase the flow rate of the airflow, drive the turbine fan blades to do work, and then generate current to provide auxiliary power for the vehicle. The arrangement of the electric opening and closing mechanism can control the opening and closing of the wind collecting hood at any time to avoid increasing wind resistance during normal driving, and can prevent flying sand from entering the wind collecting hood in bad weather. The arrangement of the silencer chamber can reduce the noise generated by the permanent magnet generator when generating electricity. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] Example 1

[0024] See attached Figure 1-5 The present embodiment discloses a closable micro-wind power generation device of an automobile air deflector duct, comprising an air collecting hood 1, an air intake duct 2, a turbine power generation mechanism and an air outlet channel 3. The air collecting hood 1 is installed in the air deflector at the top of the vehicle cab. The air collecting hood 1 is trumpet-shaped. The air inlet of the air collecting hood 1 is equipped with an electric opening and closing mechanism. The air intake duct 2 and the turbine power generation mechanism are arranged on the top of the vehicle cab. The air collecting hood 1, the air intake duct 2, the turbine power generation mechanism and the air outlet channel 3 are sequentially connected.

[0025] Specifically, the turbine power generation mechanism includes a silencer chamber 4, a mounting bracket 5, turbine blades 6 and a permanent magnet generator. The mounting bracket 5 is cross-shaped and is installed in the silencer chamber 4. The front end of the mounting bracket 5 is streamlined. The permanent magnet generator is arranged inside the mounting bracket 5. The turbine blades 6 are installed on the rotor of the permanent magnet generator. The turbine blades 6 in this embodiment are 8 pieces, which can not only make the blades more evenly distribute the wind force they bear, thereby reducing the vibration and noise caused by unbalanced load, but also avoid too many blades to increase mechanical losses, and multiple blades will interfere with each other and cause turbulent losses.

[0026] As a preferred embodiment of the present invention, the surface of the silencer chamber 4 is provided with a silencer and heat insulation layer 7 and an anti-corrosion coating 8 in sequence from the inside to the outside. By providing the silencer and heat insulation layer 7, the noise generated when the airflow passes through the generator can be effectively reduced. The provision of the anti-corrosion coating 8 increases the service life of the silencer chamber 4.

[0027] As a preferred embodiment of the present invention, it also includes a voltage stabilizing module 20, which is electrically connected to the permanent magnet generator. By setting the voltage stabilizing module 20, the voltage change caused by the constant change of the rotation speed of the turbine blade 6 can be avoided, making the output voltage more stable.

[0028] In order to be able to implement the adjustment of the intake of the duct and avoid increasing the wind resistance of the vehicle, the present invention is provided with an electric opening and closing mechanism. The electric opening and closing mechanism includes a frame 9, a louver 10, a driving shaft, a driven shaft, a driving plate 11 and a driving motor 12. A sealing gasket is provided between the frame 9 and the air inlet of the wind collecting cover 1. The driving shaft and the driven shaft are both rotatably arranged in the frame 9. The driven shaft is arranged on both sides of the driving shaft. The louver 10 is fixedly installed on the driving shaft and the driven shaft. A gear 13 is installed on the side of the driving shaft and the driven shaft close to the frame. The driving plate 11 is slidably limited in the frame 9. A rack is provided on one side of the driving plate 11 corresponding to the gear 13. The rack is meshed with the gear 13. The driving motor 12 is arranged on one side of the frame 9. The output shaft of the driving motor 12 is fixedly connected to the driving shaft. The driving motor 12 is electrically connected to the control circuit of the vehicle.

[0029] When the vehicle is driving normally, the drive motor 12 will control the rotation of the active shaft and use the gear to drive the drive plate 11 to move up and down. The drive plate 11 uses the meshing relationship between the rack and the gear 13 to drive the driven shaft to rotate, so that the louver 10 is in a closed state. Only when the control circuit detects that the vehicle is decelerating, going downhill or stopped, will the louver 10 be controlled to rotate to the maximum opening and closing state, so that the airflow can enter the wind collecting hood 1. In bad weather, the drive circuit can be manually controlled to close the electric opening and closing mechanism to prevent dust and other impurities from entering the wind collecting hood 1.

[0030] As a preferred embodiment of the present invention, it also includes a filter screen 14, which is arranged at the front end of the frame 9 for filtering air. In order to achieve real-time cleaning of the filter screen 14, a cleaning brush 15 is slidably arranged on the frame 9, a long hole 16 is opened at the upper end of the frame 9, and an upper slide groove 17 is arranged inside the long hole 16, and a lower slide groove 18 is correspondingly arranged at the bottom end of the frame 9, and bearings 22 are installed at both ends of the cleaning brush 15, which are rotatably arranged in the slide groove of the frame 9 through the bearings 22, and a handle 19 is arranged at the upper end of the cleaning brush 15, and the handle 19 passes through the long hole 16 and is located above the frame 9. By pulling the handle 19, the cleaning brush 15 can be used to clean the flying insects and leaves attached to the filter screen 14.

[0031] As a preferred embodiment of the present invention, it also includes an air circulation pipeline 21, which is connected to one side of the air outlet duct 3. The manifold of the air circulation pipeline 21 extends into the cab, and the manifold is connected to the air outlet of the air conditioner external circulation. In this way, the air intake of the vehicle's air conditioner external circulation comes in through this air duct, thereby accelerating the air external circulation of new energy vehicles.

[0032] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any slight modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
