Description

Technical Field

[0001] This utility model relates to the field of automotive spoiler technology, specifically to an adjustable automotive spoiler and an automotive vehicle. Background Technology

[0002] The range reduction problem of pure electric vehicles under high-speed conditions is mainly attributed to the fact that air resistance increases quadratically with vehicle speed, which leads to a significant increase in the energy consumption of the whole vehicle. Traditional fixed rear spoilers can only provide limited drag reduction effect at a single design point. At the same time, the turbulent airflow under the vehicle body further amplifies energy loss.

[0003] The existing utility model patent CN210555211U proposes an adjustable car spoiler. This utility model uses an electromagnetic valve to control a hydraulic cylinder to drive a telescopic rod, which in turn drives the spoiler, which is hinged to the trunk lid, to rise and fall via a connecting rod. At high speeds, the spoiler unfolds to increase the frontal area, reduce the lift coefficient, and improve stability.

[0004] As described in the above technical solution, the angle of the spoiler is adjusted by controlling the raising and lowering of one end through a hydraulic cylinder, thereby reducing air resistance according to different driving conditions. However, the above device has the problem that the overall spoiler can only swing up and down and cannot generate asymmetrical aerodynamic correction. Since the overall spoiler can only swing up and down, when the vehicle encounters crosswinds or high-speed lane changes, the pressure on both sides of the rear becomes unbalanced, forming an asymmetrical vortex. The overall spoiler cannot weaken this vortex in time, resulting in an increase in yaw moment and additional energy loss, which limits the further improvement of the driving range of pure electric vehicles.

[0009] The drive structure includes two sets, which are respectively located at the bottom of the plate corresponding to the two wind vanes and are connected to the corresponding wind vanes for driving the wind vanes to rotate in order to adjust the opening of the airflow holes.

[0010] The sensing structure includes a sensing component located at the top of the plate and a PLC controller located at the bottom of the plate. The PLC controller is electrically connected to the sensing component and the drive structure, and is used to collect vehicle driving parameters and control the drive structure to adjust the angle of the corresponding wind vane.

[0011] Optionally, the wind vane includes airfoils and a rotating shaft, wherein,

[0012] The wing is disposed inside the airflow hole;

[0013] The rotating shaft includes two shafts, which are symmetrically arranged on both sides of the end of the vane facing the windshield of the car, and are used to be inserted into the side wall of the airflow hole and rotatably connected thereto.

[0014] Optionally, the feature is that the wind vane further includes a stop block, which is disposed at the bottom of the end of the vane away from the rotation axis, and a stop surface adapted to the stop block is provided at the bottom of the plate body to restrict the vane from rotating towards the top of the plate body.

[0024] This utility model also provides a car, including the above-mentioned adjustable car spoiler.

[0025] Compared with the prior art, the adjustable spoiler and automobile provided by this utility model have the following beneficial effects:

[0026] (1) Through the integrated design of spoiler body, wind wing, drive structure and sensing structure, PLC controller is electrically connected with sensing components and drive motor, realizing the function of dynamically adjusting the opening of wind wing on both sides according to real-time parameters such as vehicle speed and wind direction. It can independently control the airflow channels on both sides under high speed or crosswind conditions, significantly weakening asymmetric vortex and yaw moment, taking into account low wind resistance and high stability, reducing energy consumption and improving range.

[0027] (2) The wind vane adopts a hinged structure with the rotating shaft in front, which allows the vane to rotate precisely around the leading edge. The stop block and stop surface limit the maximum rotation angle to prevent over-rotation failure. The arc-shaped protective cotton provides flexible cushioning when the vane flips down, protecting the rear windshield and eliminating abnormal noise. The gear transmission mechanism achieves high-precision angle control through direct motor drive, which is fast-responding and occupies little space. The combination of the protective cover and heat dissipation holes is dustproof, waterproof, and heat dissipation efficient, extending the life of the motor. The overall structure is simple and reliable and easy to maintain.

[0028] (3) By arranging wind direction sensors and wind speed sensors on both sides of the top of the spoiler, the difference in airflow between the left and right sides of the vehicle body can be obtained in real time. The PLC controller can predict crosswind or lane change conditions in advance and independently adjust the differential opening of the left and right wings to achieve rapid asymmetric aerodynamic correction and significantly reduce lateral torque. At the same time, the opening of the airflow hole is intelligently optimized according to the real-time wind speed. When driving at high speed, it is opened as needed to balance the pressure and resistance, significantly improving the range of pure electric vehicles in crosswind conditions.

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] Please see Figure 1-5 This application proposes an adjustable automotive spoiler, comprising a spoiler body 1, a wind vane 2, a drive structure 3, and a sensing structure 4.

[0037] like Figure 1-5 As shown, the spoiler body 1 includes a plate 11 and mounting side plates 12. An airflow hole 101 is provided in the middle of the plate 11. The mounting side plates 12 include two plates, which are symmetrically arranged at the bottom of both ends of the plate 11 for mounting on the upper edge of the rear windshield of the car. The wind vanes 2 include two symmetrically arranged wind vanes, which are movably arranged in the airflow hole 101. In the initial state, the mating edges of the two wind vanes 2 are sealed to close the airflow hole 101. The drive structure 3 includes two sets, which are respectively arranged at the bottom of the plate 11 corresponding to the two wind vanes 2 and are drivenly connected to the corresponding wind vanes 2 for driving the wind vanes 2 to rotate to adjust the opening of the airflow hole 101. The sensing structure 4 includes a sensing component 41 located at the top of the plate 11 and a PLC controller 42 located at the bottom of the plate 11. The PLC controller 42 is electrically connected to the sensing component 41 and the drive structure 3 for collecting vehicle driving parameters and controlling the drive structure 3 to adjust the angle of the corresponding wind vanes 2.

[0038] Specifically, this integrated design uses a PLC controller 42 to link the sensing component 41 and the drive structure 3 to dynamically adjust the opening of the wind vane 2. Under high-speed or crosswind conditions, the PLC controller 42 controls the drive structure 3 to drive the two wind vanes 2 according to the wind speed and direction information collected by the sensing component 41, and adjusts the opening angle of the left and right wind vanes 2 respectively, so that the airflow hole 101 opens as needed. The left and right wind vanes 2 can move asynchronously to form an asymmetric airflow channel, which specifically weakens the asymmetric vortex, reduces the yaw moment, and balances low drag and high stability, solving the problem that traditional integrated spoilers cannot cope with lateral airflow imbalance.

[0039] In some embodiments, such as Figure 5 As shown, the wind vane 2 includes a blade 21 and a rotating shaft 22. The blade 21 is disposed inside the airflow hole 101. The rotating shaft 22 includes two shafts, which are symmetrically disposed on both sides of the end of the blade 21 facing the windshield of the car, for inserting into the side wall of the airflow hole 101 and rotatably connected thereto.

[0040] Specifically, the front-mounted design of the rotating shaft 22 causes the vane 21 to rotate around its leading edge. When the vane 21 is open, the airflow passes downward through the airflow hole 101. Under high-speed or crosswind conditions, the airflow hole 101 is partially opened. The combination of the airflow hole 101 and the vane 21 forms an adjustable pressure relief channel, allowing some high-speed airflow to be forced through the spoiler and discharged downward, releasing the high pressure at the top in advance. At the same time, this penetrating airflow forms a controllable secondary adhering flow along the upper edge of the rear window, which increases downforce and interferes with and weakens the vortex that would normally fall off alternately on both sides of the rear, thus reducing the overall vehicle pressure drag and yaw moment simultaneously, thereby reducing energy consumption under high-speed or crosswind conditions.

[0041] In some embodiments, such as Figure 3 , Figure 5 As shown, the wind vane 2 also includes a stop block 23 and an arc-shaped protective cotton 24. The stop block 23 is located at the bottom of the end of the vane 21 away from the rotation axis 22. A stop surface 102 adapted to the stop block 23 is provided at the bottom of the plate 11 to restrict the vane 21 from rotating towards the top of the plate 11. The arc-shaped protective cotton 24 is located at the bottom of the stop block 23 to prevent rigid contact between the vane 21 and the rear windshield when the vane 21 flips downward.

[0042] Specifically, when the drive structure 3 drives the vane 21 to swing downwards, the stop block 23 enters the stop surface 102 and is blocked by the groove wall, forming a mechanical limit to prevent the vane 21 from continuing to flip upwards and affecting the normal use of the spoiler. At the same time, the arc-shaped protective cotton 24 first contacts the glass surface when the vane 21 swings downwards quickly or when the vehicle is bumpy. The flexible arc-shaped protective cotton 24 absorbs the impact and isolates the hard friction between the metal and the glass, thereby avoiding glass scratches, cracks and abnormal noises, and ensuring that the spoiler maintains structural integrity and quiet operation during long-term use.

[0043] In some embodiments, such as Figure 5As shown, the drive structure 3 includes a drive motor 31, a first gear 32, a second gear 33, and a protective cover 34. The drive motor 31 is located at the bottom of the plate 11 and corresponds to one of the rotating shafts 22 of the corresponding wind vane 2. The drive motor 31 is electrically connected to the PLC controller 42. The first gear 32 is fixedly located at the drive end of the drive motor 31. A clearance groove 103 is provided at the bottom of the plate 11 corresponding to the first gear 32. The second gear 33 is located in the clearance groove 103 and meshes with the first gear 32. The end of the corresponding rotating shaft 22 extends into the clearance groove 103 and is fixedly connected to the second gear 33. The protective cover 34 is located at the bottom of the plate 11 and covers the outside of the drive motor 31 to protect the entire drive structure 3. The protective cover 34 has multiple heat dissipation holes 301.

[0044] Specifically, after the drive motor 31 starts, the torque is directly transmitted to the rotating shaft 22 via a two-stage gear system, allowing the spoiler 2 to quickly swing down or retract around its leading edge. The gear transmission eliminates the need for connecting rods and hydraulic lines, resulting in a compact structure and good synchronization. Simultaneously, the protective cover 34 isolates the drive motor 31 and gears from external mud, sand, and rainwater, reducing jamming and corrosion. The heat dissipation holes 301 allow air convection inside and outside the cover, promptly removing heat from the drive motor 31 and preventing overheating failure. The overall solution achieves a closed-loop system of rapid response, reliable protection, and self-sustaining heat dissipation within a limited space, ensuring that the spoiler can still adjust the angle of the spoiler 2 as needed during long-term use, maintaining overall vehicle aerodynamic optimization.

[0045] In some embodiments, such as Figure 1-2 , Figure 4 As shown, the sensing component 41 includes a wind direction sensor 411 and a wind speed sensor 412. The wind direction sensor 411 and the wind speed sensor 412 are located on the top of the plate 11 and are electrically connected to the PLC controller 42. At the same time, the sensing component 41 includes two sets, which are located on the top of the plate 11 and on both sides of the vehicle body, for simultaneously collecting driving parameters on both sides of the vehicle body.

[0046] Specifically, two sets of sensors collect real-time information on the direction and speed of the incoming airflow from the left and right sides of the vehicle body, and transmit it synchronously to the PLC controller 42. The controller immediately determines the crosswind or lane change condition based on the difference between the two sides, and then independently adjusts the opening angle of the left and right wind vanes 2 to achieve asymmetric airflow control. This dual-side independent monitoring and differentiated control method enables the spoiler to respond quickly to changes in lateral airflow, weaken the rear vortex, and maintain vehicle stability. Note: If the vehicle body already has a wind direction sensor 411 and a wind speed sensor 412, they can be electrically connected to the PLC controller 42, eliminating the need to install additional wind direction and wind speed sensors.

[0047] The PLC controller 42 and its control method, as well as the wind direction sensor 411 and the wind speed sensor 412 and their working principles, are all existing technologies and will not be described in detail here.

[0048] This utility model also provides a car, including the above-mentioned adjustable car spoiler, which is integrated into the upper edge of the rear windshield of the car, so that the whole vehicle has a dynamically adjustable rear aerodynamic device, reducing energy consumption and enhancing driving stability.

[0049] The specific workflow is as follows:

[0050] During vehicle operation, the wind direction sensor 411 and wind speed sensor 412 of the top sensing component 41 sense the wind direction and wind speed in real time. The PLC controller 42 judges the operating conditions based on this and immediately commands the drive motors 31 on both sides. When driving at high speed or in crosswind, the drive motors 31 drive the corresponding wind vanes 2 to swing down around the leading edge through the gear pair. The airflow hole 101 opens as needed, allowing the high-pressure airflow at the top to be released downward and form an adhering flow at the rear window, which weakens the tail vortex and suppresses yaw, thereby further improving the range.
