Technical Field

[0001] The present invention relates to the technical field of wind energy recovery automotive parts, and particularly to a front grille assembly of a vehicle with wind energy recovery and a preparation method thereof. Background Art

[0002] With the intensification of the global energy crisis and the improvement of environmental protection awareness, energy conservation and emission reduction have become an important direction for the development of the automotive industry; during the driving process of traditional vehicles, a large amount of wind energy is wasted and not effectively utilized.

[0003] Existing wind energy recovery devices are mostly independently installed on the roof or the side of the vehicle body, which destroys the overall design of the vehicle and has low recovery efficiency; the existing front grille of the vehicle mainly plays the roles of heat dissipation and aesthetics, and the kinetic energy of the airflow generated during high-speed driving is not effectively utilized, resulting in energy waste. Therefore, the present invention proposes a front grille assembly of a vehicle with wind energy recovery and a preparation method thereof to solve the problems existing in the prior art. Summary of the Invention

[0004] Aiming at the above problems, the purpose of the present invention is to propose a front grille assembly of a vehicle with wind energy recovery and a preparation method thereof. The front grille assembly of the vehicle with wind energy recovery and the preparation method can effectively utilize the airflow energy passing through the grille during the driving process of the vehicle, convert it into electrical energy or other forms of energy, and store it for the vehicle to use or as a backup, improving the energy utilization efficiency of the vehicle and reducing energy consumption; the dynamically adjustable deflector vane array can maximize the wind energy capture efficiency, and the intelligent energy storage system can detect and optimize the adjustment of the deflector vane angle and the power generation power in real time, so as to improve the wind energy recovery efficiency.

[0005] To achieve the objectives of the present invention, the present invention is implemented through the following technical solutions: A front grille assembly of a vehicle with wind energy recovery includes a mask grille body frame, an adjustable vane mechanism, an air intake port, an energy conversion mechanism, and an intelligent control energy storage system. The adjustable vane mechanism includes a guide vane array, a linkage rotating rod, and an adjustment mechanism. The guide vane array is symmetrically distributed within the mask grille body frame. The guide vane array is composed of multiple groups of vanes. The outer ends of the guide vane array are distributed with linkage rotating rods. Both ends of the guide vane array are rotationally connected to the inner side walls of the mask grille body frame through rotating shafts. The linkage rotating rods are fixedly connected to the rotating shafts extending out of the mask grille body frame. An adjustment mechanism is provided on the side surface of the mask grille body frame. The adjustment mechanism is adapted to the linkage rotating rod. By driving the linkage rotating rod through the adjustment mechanism, the inclination angle adjustment of the guide vane array is realized. An air intake port is provided at the rear side of the mask grille body frame. The energy conversion mechanism includes a generator, wind turbine blades, and a piezoelectric energy conversion mechanism. Generators are symmetrically arranged within the air intake port. Wind turbine blades are provided at the ends of the generators for converting the kinetic energy of the airflow entering the air intake port into electrical energy. A piezoelectric energy conversion mechanism is provided at the rear side of the air intake port. The intelligent control energy storage system based on multiple groups of sensors monitors the vehicle speed, wind speed, and battery status in real time and dynamically optimizes the angle of the guide vane array and the power generation power.

[0006] A further improvement lies in that: The adjustment mechanism includes an electric adjustment rod, an adjustment slide rod, and an adjustment guide groove. Electric adjustment rods are symmetrically arranged up and down on one side of the mask grille body frame, and the telescopic ends are distributed oppositely. The telescopic ends of the electric adjustment rods are fixedly provided with adjustment slide rods. An adjustment guide groove is provided at one end of the linkage rotating rod. The adjustment slide rod is movably adapted to the adjustment guide groove.

[0007] A further improvement lies in that: Adaptation cylinders are symmetrically arranged on the side of the adjustment slide rod close to the linkage rotating rod. The adaptation cylinders are inserted into the adjustment guide groove for movable adaptation. Guide seats are symmetrically arranged on the side surface of the mask grille body frame between the linkage rotating rods. The adjustment slide rod passes through the guide seats and is slidably adapted thereto. By controlling the rotation of the linkage rotating rod through the electric adjustment rod, the inclination angle adjustment of the guide vane array is realized.

[0008] A further improvement lies in that: The guide vane array is divided into upper and lower groups and is controlled by the adjustment mechanism. The lower guide vane array adjusts its inclination angle upward, and the upper guide vane array adjusts its inclination angle downward. The inclination angle adjustment range is between 0° and 30°. Angle sensors are provided at the ends of the guide vane array away from the linkage rotating rods for detecting and feedbacking the inclination angles of the guide vane arrays.

[0009] A further improvement lies in that: the piezoelectric transducer mechanism includes a fixing frame, a guide plate, a multi-section electric rod, an adjustment orifice plate, and a piezoelectric ceramic power generation sheet array. Fixing frames are symmetrically arranged on the mask grille body frame at the rear side of the air intake opening. A guide plate is arranged between the fixing frames. A multi-section electric rod is arranged on the fixing frames. An adjustment orifice plate is arranged below the multi-section electric rod. The adjustment orifice plate is located at the front side of the guide plate and is slidably adapted thereto. Piezoelectric ceramic power generation sheet arrays are symmetrically arranged on the outer side of the adjustment orifice plate, and the kinetic energy of the air flow can be converted into electric energy through the piezoelectric effect.

[0010] A further improvement lies in that: the cross-section of a single blade in the guide vane array is in the shape of a horizontal water droplet. The guide vane array is formed by 3D printing, and a nano-hydrophobic coating is coated on the surface of each blade.

[0011] A further improvement lies in that: the intelligent control energy storage system includes a detection module, a central control processing module, an instruction interaction module, and an energy storage module. The detection module real-time detects the vehicle speed, wind speed, and remaining battery power based on a speed sensor. The central control processing module performs data processing based on an MCU chip and outputs an adjustment instruction. The instruction interaction module is used to identify the adjustment instruction and control the adjustable vane mechanism and the transducer mechanism to adjust and operate. The energy storage module is used to store the electric energy converted by the transducer mechanism.

[0012] A preparation method for a vehicle front mask grille assembly with wind energy recovery includes the following steps:

[0013] Step 1: Mix a ternary polymer modified resin and polymethyl methacrylate, add carbon fiber and additives, and fully stir. Finally, use the method of compression thermoplastic molding to produce the mask grille body frame.

[0014] Step 2: Use 3D printing to print the independent blades of the guide vane array, and use carbon fiber reinforced polymer prepreg for hot pressing and curing treatment to obtain the formed blades.

[0015] Step 3: Use fluorine-modified nano-SiO2 as an auxiliary material, spray and cure it on the formed blades with a contact angle greater than 150° with the PU-PMMA copolymer emulsion to form a nano-hydrophobic coating, and obtain the independent blades of the guide vane array.

[0016] Step 4: Combine and install multiple groups of independent blades in the mask grille body frame, install a linkage rotating rod and connect it to the adjustment mechanism on the side of the mask grille body frame. Finally, install the transducer mechanism at the rear side of the mask grille body frame and connect it to the intelligent control energy storage system.

[0017] A further improvement lies in that: the auxiliary agent in the above step includes a toughening agent and an antioxidant, and the mixing weight ratio of the ternary polymerization modified resin, polymethyl methacrylate, carbon fiber, toughening agent and antioxidant is 35-45:30-40:12-15:3-4:3-4.

[0018] A further improvement lies in that: in the above step three, the spraying is specifically carried out with a PU-PMMA copolymer emulsion as the spraying fluid. During spraying, nano-SiO2 is sucked into the spraying fluid by the negative pressure of the high-speed fluid and sprayed on the formed blade.

[0019] The beneficial effects of the present invention are as follows: by designing a front mask grille structure with wind energy recovery, the present invention can effectively utilize the airflow energy passing through the grille during vehicle driving, convert it into electrical energy or other forms of energy, and store it for vehicle use or standby, improving the energy utilization efficiency of the vehicle and reducing energy consumption;

[0020] The dynamically adjustable deflector blade array can maximize the wind energy capture efficiency, and the intelligent control energy storage system can detect and optimize the adjustment of the deflector blade angle and power generation power in real time, improving the wind energy recovery efficiency.

Both ends of the deflector vane array are rotationally connected to the inner side wall of the mask grille body frame by a rotating shaft. The linkage rotating rod is fixedly connected to the rotating shaft extending out of the mask grille body frame. An adjustment mechanism is arranged on the side of the mask grille body frame 1. The adjustment mechanism is adapted to the linkage rotating rod 4. By driving the linkage rotating rod through the adjustment mechanism, the inclination angle of the deflector vane array is adjusted. There is an air intake port 2 at the rear of the mask grille body frame 1. The energy conversion mechanism includes a generator 5, a wind turbine blade 6, and a piezoelectric energy conversion mechanism. The generators 5 are symmetrically arranged inside the air intake port 2. The wind turbine blade 6 is arranged at the end of the generator 5 for converting the kinetic energy of the air flowing into the air intake port into electrical energy. There is a piezoelectric energy conversion mechanism at the rear of the air intake port 2 for further recovering and utilizing the kinetic energy of the air flow. The intelligent control energy storage system based on multiple groups of sensors monitors the vehicle speed, wind speed, and battery state in real time and dynamically optimizes the angle of the deflector vane array 3 and the power generation.

[0031] The adjustment mechanism includes an electric adjustment rod 7, an adjustment slide rod 8, and an adjustment guide groove 9.

The telescopic ends of the electric adjustment rods 7 are fixedly provided with the adjustment slide rod 8. One end of the linkage rotating rod 4 is provided with the adjustment guide groove 9. The adjustment slide rod 8 is movably adapted to the adjustment guide groove 9.

[0032] On the side of the mask grille body frame 1 between the linkage rotating rods 4, there are symmetrically arranged guide seats 11. The adjustment slide rod 8 passes through the guide seats 11 and is slidably adapted to them. By controlling the rotation of the linkage rotating rod through the electric adjustment rod, the inclination angle of the deflector vane array is adjusted. The dynamically adjusted deflector vane array can maximize the wind energy capture efficiency.

[0033] The deflector vane array 3 is divided into upper and lower groups and is controlled by the adjustment mechanism. The lower deflector vane array 3 adjusts the inclination angle upward, and the upper deflector vane array 3 adjusts the inclination angle downward. The inclination angle adjustment range is between 0° and 30°. An angle sensor 12 is arranged at the end of the deflector vane array 3 away from the linkage rotating rod 4 for detecting and feedbacking the inclination angle of the deflector vane array.

[0034] The piezoelectric energy conversion mechanism includes a fixing frame 13, a guiding plate 14, a multi-section electric rod 15, an adjusting orifice plate 16, and a piezoelectric ceramic power generation sheet array 17.

Piezoelectric ceramic power generation sheet arrays 17 are symmetrically arranged outside the adjusting orifice plate 16, which can convert the kinetic energy of the air flow into electric energy through the piezoelectric effect to further recover wind energy.

[0035] The cross-section of a single blade in the guide vane array 3 is horizontally water-drop-shaped. The guide vane array 3 is formed by 3D printing and a nano-hydrophobic coating is applied to the surface of each blade to reduce wind resistance.

[0036] The intelligent control energy storage system includes a detection module, a central control processing module, an instruction interaction module, and an energy storage module. The detection module based on a speed sensor real-time detects the vehicle speed, wind speed, and remaining battery power. The central control processing module performs data processing based on an MCU chip and outputs adjustment instructions. The instruction interaction module is used to identify the adjustment instructions and control the adjustable vane mechanism and the energy conversion mechanism to adjust and operate. The energy storage module is used to store the electric energy converted by the energy conversion mechanism.

[0037] The intelligent control energy storage system can real-time detect and optimize the adjustment of the guide vane angle and power generation power. When the vehicle speed ≥ 60 km / h, the blade inclination angle is adjusted to 15°, giving priority to capturing high-speed air flow. When the vehicle speed ≤ 30 km / h, the blade resets to 0°, reducing the impact of wind resistance on endurance and increasing the wind energy recovery efficiency by 20% - 35%.
