Description

Technical Field

[0001] This utility model relates to the field of automotive aerodynamics technology, and in particular to an aerodynamic structure for commercial vehicles that can automatically adjust wind resistance. Background Technology

[0002] In today's commercial vehicle industry, energy conservation, emission reduction, and efficient transportation have become core pursuits. When commercial vehicles are traveling at high speeds, air resistance has a significant impact on their fuel consumption and driving stability. According to research, air resistance increases by about 15% for every 10 km / h increase in vehicle speed. To reduce resistance, fairings have emerged. They can effectively optimize the airflow around the vehicle, reduce air turbulence, lower the drag coefficient, and thus reduce fuel consumption and improve transportation efficiency.

[0003] Existing commercial vehicle aerodynamic structures vary, with some employing adjustable fairings, such as some lift-type fairing mechanisms. These fairings open before the vehicle travels at high speeds to disrupt airflow, reduce rear cargo wind pressure, and decrease the drag coefficient. However, these adjustable fairings have significant drawbacks in practical applications. The gap at the front end where they connect to the vehicle's front base is relatively large. When the vehicle is traveling at high speeds, airflow can easily enter through this gap. A large influx of airflow disrupts the originally stable airflow field, affecting the fairing's guiding effect on the airflow. This prevents the airflow from flowing along the expected path, reducing guiding efficiency. At the same time, the continuous impact of airflow within the gap causes additional vibrations to the fairing. Over time, this not only affects the stability of the fairing itself but also damages the connection structure, reduces equipment lifespan, and increases maintenance costs and safety hazards. Utility Model Content

[0004] To overcome the problem that existing commercial vehicle spoiler structures have a large gap at the front end of the connection between the adjustable fairing and the vehicle's front base, which causes airflow to easily enter the gap when the vehicle is traveling at high speed, affecting the stability of the fairing, reducing airflow guiding efficiency, and shortening the service life of the equipment, this utility model provides a commercial vehicle spoiler structure with automatically adjustable wind resistance.

[0005] The technical solution is as follows: A commercial vehicle spoiler structure with automatic wind resistance adjustment includes a fairing assembly, a slit baffle, and a truck; the truck is arranged below the fairing assembly; the slit baffle is arranged at the front end of the fairing assembly; the fairing assembly includes a base, a fairing, an inner side plate, a connecting shaft, a rotating slide, an elevation adjustment cylinder, a bracket, and a six-component force sensor.

[0006] Furthermore, a base is provided at the upper part of the truck's front end, and the base is fixedly connected to the truck by bolts; a fairing is provided at the upper end of the base, and a slit baffle is fixedly connected to the front end face of the fairing.

[0007] Furthermore, both ends of the fairing are provided with connecting shafts, which connect the base and the fairing together for rotational connection.

[0008] Furthermore, six force sensors are installed at the four corners of the upper surface of the fairing, and the model of the six force sensors is FC6D190.

[0009] Furthermore, the inner wall of the fairing is provided with an inner side plate, and the inner side plate is integrally formed with the base; an elevation adjustment cylinder is provided between the base and the fairing, and the outer shell of the elevation adjustment cylinder is fixedly connected to the base.

[0010] Furthermore, a bracket is provided at the upper end of the output end of the elevation adjustment cylinder, and the outer shell of the bracket is fixedly connected to the lower end face of the guide fairing. The bracket is rotatably connected to the output end of the elevation adjustment cylinder, and the control unit of the elevation adjustment cylinder dynamically adjusts the lifting height based on the detection data of the six-component force sensor.

[0011] Furthermore, a rotating groove is provided on the outer side of the inner side plate, and the rotating groove is integrally formed with the guide shroud. The protruding column on the outer side of the inner side plate is slidably arranged along the inside of the rotating groove.

[0012] The beneficial effects are as follows: This utility model uses a six-component force sensor to monitor the pressure of the airflow above the shroud in real time, thereby calculating the wind resistance at the four corners of the shroud. Based on the wind resistance distribution, the elevation angle adjustment cylinder pushes the adjustment bracket and the shroud around the connecting shaft to dynamically adjust the elevation angle of the shroud to achieve the function of minimizing wind resistance. The baffle is used to cover the gap between the front end of the shroud and the base. Since the baffle is fixedly installed on the front end of the shroud, it can effectively cover the gap, thereby effectively improving the airflow guiding efficiency and preventing high-speed airflow from rushing into the gap, affecting the structural stability, generating noise and increasing wind resistance.

[0013] By incorporating the inner side plate and rotating slide, the inner side plate effectively enhances the dustproof and waterproof performance of the inner side of the air guide, thereby improving equipment reliability. When the air guide is rotated for adjustment, the rotating slide is limited by the protruding column on the outer side of the inner side plate, effectively improving the stability of the air guide during adjustment and reducing shaking.

[0020] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0023] The truck 3 has a base 101 at the upper end of the front part, and the base 101 is fixedly connected to the truck 3 by bolts; the upper end of the base 101 is provided with a fairing 102, and the gap baffle 2 is fixedly connected to the front end face of the fairing 102.

[0024] Both ends of the flow guide 102 are provided with connecting shafts 104, and the connecting shafts 104 connect the base 101 and the flow guide 102 together for rotational connection.

[0025] The upper surface of the fairing 102 is equipped with six-component force sensors 108 at each of the four corners, and the model of the six-component force sensors 108 is FC6D190.

[0026] The inner wall of the fairing 102 is provided with an inner side plate 103, and the inner side plate 103 is integrally formed with the base 101; an elevation angle adjustment cylinder 106 is provided between the base 101 and the fairing 102, and the outer shell of the elevation angle adjustment cylinder 106 is fixedly connected to the base 101.

[0027] A bracket 107 is provided at the upper end of the output end of the pitch adjustment cylinder 106, and the outer shell of the bracket 107 is fixedly connected to the lower end face of the guide shroud 102. The bracket 107 is rotatably connected to the output end of the pitch adjustment cylinder 106. The control unit of the pitch adjustment cylinder 106 dynamically adjusts the lifting height according to the detection data of the six-component force sensor 108.

[0028] The pressure of the airflow above the shroud 102 is monitored in real time by a six-component force sensor 108, thereby calculating the wind resistance at the four corners of the shroud 102. Based on the wind resistance distribution, the elevation angle adjustment cylinder 106 pushes the adjustment bracket 107 and the included angle of the shroud 102 around the connecting shaft 104, thereby realizing the function of dynamically adjusting the elevation angle of the shroud 102 to achieve the minimum wind resistance. The baffle 2 is used to cover the gap at the front end between the shroud 102 and the base 101. Since the baffle 2 is fixedly installed on the front end of the shroud 102, it can effectively cover the gap, thereby effectively improving the airflow guiding efficiency and preventing high-speed airflow from rushing into the gap, affecting the structural stability, generating noise and increasing wind resistance.

The protruding column on the outer side of the inner side plate 103 is slidably arranged along the inside of the rotating groove 105.

[0031] With the inner side plate 103 and the rotating slide 105, the inner side plate 103 effectively improves the dustproof and waterproof performance of the inner side of the flow guide 102, and effectively improves the reliability of the equipment. When the flow guide 102 is rotated and adjusted, the rotating slide 105 is limited by the protruding column on the outer side of the inner side plate 103, which effectively improves the stability of the flow guide 102 during adjustment and reduces shaking.
