Description

Technical Field

[0001] This application relates to the field of vehicles, and in particular to a spoiler assembly for a vehicle and the vehicle thereof. Background Technology

[0002] In related technologies, vehicles are often equipped with spoilers, which not only make the car's appearance more dynamic, but also reduce air resistance during high-speed driving, reduce fuel consumption, and improve the car's grip and stability. With the development of new energy vehicles, spoilers play an important role in reducing air resistance, thereby reducing the vehicle's energy consumption and improving its range. However, the current spoiler structure is a flat spoiler, which has a limited effect on reducing wind resistance. Therefore, how to further reduce the wind resistance of vehicles has become the technical problem to be solved in this application. Utility Model Content

[0003] This application aims to address at least one of the technical problems existing in the prior art. To this end, one objective of this application is to provide a spoiler assembly for a vehicle that can further reduce the vehicle's wind resistance.

[0004] This application also proposes a vehicle with aerodynamic components.

[0005] A spoiler assembly for a vehicle according to an embodiment of this application includes: a base body adapted to be connected to the rear of a vehicle body, the base body extending in a width direction, and an air guide surface formed on the upper surface of the base body; a first air guide and a second air guide, the first air guide and the second air guide being symmetrically disposed at both ends of the base body, at least a portion of the first air guide and at least a portion of the second air guide protruding from the air guide surface, the first air guide and the second air guide being spaced apart in the vehicle width direction, wherein the first air guide and the second air guide have a first air passage wall and a second air passage wall respectively formed on their respective side edges facing each other, the first air passage wall and the second air passage wall being inclined away from each other in a direction close to the air guide surface, a first concave air passage being formed between the first air passage wall and the air guide surface, and a second concave air passage being formed between the second air passage wall and the air guide surface.

[0006] According to an embodiment of this application, a spoiler assembly for a vehicle is provided by first and second air duct walls that are inclined away from each other in the direction close to the air guide surface. A first concave air duct and a second concave air duct are formed between the first and second air duct walls and the air guide surface, respectively. Above the concave air duct, the airflow has a longer path and slower speed due to the circumference of the protruding air guide edge, forming a relatively high-pressure area. Inside the concave air duct, i.e., between the air guide surface and the air duct wall, the airflow speed is increased due to the contraction of the cross-sectional area, forming a local low-pressure area. The high-pressure area points to the low-pressure area, generating suction perpendicular to the air guide surface, i.e., a downward pressure component, which counteracts the lift caused by the air pressure difference between the roof and the bottom of the vehicle, making the vehicle body more stable and closer to the ground. This reduces airflow separation and vortices caused by lift, thereby reducing wind resistance. The increase in downforce not only suppresses vehicle lifting but also delays the airflow separation at the rear through the concave air duct, achieving the dual effects of stability and wind resistance reduction.

[0007] According to some embodiments of the present application, a spoiler assembly for a vehicle has a first windward wall formed on the wall of the first air guide facing the side of the vehicle's forward movement, and the first windward wall is connected to the first air duct wall via a first inner side wall; a second windward wall is formed on the wall of the second air guide facing the side of the vehicle's forward movement, and the second windward wall is connected to the second air duct wall via a second inner side wall; wherein the first inner side wall and the second inner side wall are spaced apart in the vehicle width direction, and the first inner side wall and the second inner side wall are inclined toward each other in the direction toward the rear of the vehicle.

[0008] According to some embodiments of this application, a spoiler assembly for a vehicle has a first air-lifting protrusion formed on the first windward wall, the first air-lifting protrusion protruding beyond the air-guiding surface, and the top surface of the first air-lifting protrusion connected to the top surface of the first air-guiding member; a second air-lifting protrusion is formed on the second windward wall, the second air-lifting protrusion protruding beyond the air-guiding surface, and the top surface of the second air-lifting protrusion connected to the top surface of the second air-guiding member.

[0009] According to some embodiments of this application, a spoiler assembly for a vehicle has a first transition concave surface between the side of the first air-lifting protrusion near the center of the base body and the first air duct wall, the first transition concave surface being recessed towards the rear of the vehicle, and the first inner sidewall being constructed as the first transition concave surface; a second transition concave surface between the side of the second air-lifting protrusion near the center of the base body and the second air duct wall is provided, the second transition concave surface being recessed towards the rear of the vehicle, and the second inner sidewall being constructed as the second transition concave surface.

[0010] According to some embodiments of the present application, a spoiler assembly for a vehicle has a first extension protrusion formed on the outer side of the first air guide extending toward the rear of the vehicle, the first extension protrusion having a gradually decreasing cross-section in the direction toward the rear of the vehicle; and a second extension protrusion formed on the outer side of the second air guide extending toward the rear of the vehicle, the second extension protrusion having a gradually decreasing cross-section in the direction toward the rear of the vehicle.

[0011] According to some embodiments of this application, a spoiler assembly for a vehicle has a first air guide and a second air guide constructed as separate parts, and the base body is connected to the first air guide and the second air guide respectively by fasteners.

[0012] According to some embodiments of this application, a spoiler assembly for a vehicle has a base body with a first connecting plate and a second connecting plate at both ends, the width of which gradually decreases outwards. The first connecting plate has a first fixing part at its rear edge, which is directly opposite to and engaged with at least a portion of the first air guide in the thickness direction. The second connecting plate has a second fixing part at its rear edge, which is directly opposite to and engaged with at least a portion of the second air guide in the thickness direction.

[0013] According to some embodiments of this application, a spoiler assembly for a vehicle includes a base body comprising: an inner body plate adapted to be fixed to the vehicle body, wherein a first fixing portion and a second fixing portion are respectively provided on both sides of the width of the inner body plate; and an outer body plate that mates with the inner body plate in the thickness direction, wherein the first fixing portion and the second fixing portion protrude from the edge of the outer body plate.

[0014] According to some embodiments of this application, a spoiler assembly for a vehicle includes a first air guide member comprising: a first inner air guide plate and a first outer air guide plate, wherein the first inner air guide plate and the first outer air guide plate are configured to cooperate in the thickness direction, the bottom of the first outer air guide plate forms a first mounting area that cooperates with the first fixing portion, and the first inner air guide plate forms a first clearance notch that avoids the first mounting area; the second air guide member includes: a second inner air guide plate and a second outer air guide plate, wherein the second inner air guide plate and the second outer air guide plate are configured to cooperate in the thickness direction, the bottom of the second outer air guide plate forms a second mounting area that cooperates with the second fixing portion, and the second inner air guide plate forms a second clearance notch that avoids the second mounting area.

[0015] The spoiler assembly for a vehicle according to some embodiments of this application further includes: a camera shield disposed on the base body and protruding from the air guide surface, the camera shield having a gradually decreasing width in a direction away from the air guide surface, and an accommodating space formed inside the camera shield; and a camera, at least a portion of which is housed within the accommodating space.

[0016] The vehicle according to an embodiment of this application is briefly described below.

[0017] The vehicle according to the embodiments of this application includes the spoiler assembly described in any of the above embodiments. Since the vehicle according to this embodiment is equipped with the spoiler assembly described in any of the above embodiments, the vehicle according to the embodiments of this application has lower wind resistance. For new energy vehicles, reduced wind resistance directly reduces driving power consumption and can increase the driving range with the same battery capacity. For fuel vehicles, it can reduce fuel consumption and improve economy. At the same time, the symmetrical first concave air passage and the second concave air passage form a low-pressure area on the roof through the Bernoulli effect, generating downward additional pressure, effectively counteracting the lift generated by the air pressure difference between the roof and the bottom of the vehicle when the vehicle is driving at high speed, suppressing the lift of the vehicle body, increasing the tire ground load, improving grip, and reducing the risk of sideslip. The symmetrically arranged air guides guide the airflow to flow orderly along the concave air passage, delaying the separation of the rear airflow, reducing turbulence interference around the vehicle body, which can significantly reduce the lateral deviation of the vehicle, making the driving posture more stable and the handling response more precise.

[0018] Additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

[0049] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0050] The following is for reference. Figures 1-8 Describes a spoiler assembly 100 for a vehicle according to an embodiment of this application.

[0051] A spoiler assembly 100 for a vehicle according to an embodiment of this application includes a base body 1, a first air guide 2, and a second air guide 3. The base body 1 is adapted to be connected to the rear of the vehicle body and extends in the width direction. An air guide surface 11 is formed on the upper surface of the base body 1. The first air guide 2 and the second air guide 3 are symmetrically arranged at both ends of the base body 1. At least a portion of the first air guide 2 and at least a portion of the second air guide 3 protrudes from the air guide surface 11. The first air guide 2 and the second air guide 3 are spaced apart in the width direction of the vehicle. A first air passage wall 21 and a second air passage wall 31 are formed on the two side edges of the first air guide 2 and the second air guide 3 facing each other, respectively. The first air passage wall 21 and the second air passage wall 31 are inclined away from each other in the direction close to the air guide surface 11. A first concave air passage 22 is formed between the first air passage wall 21 and the air guide surface 11, and a second concave air passage 32 is formed between the second air passage wall 31 and the air guide surface 11.

[0052] It is understandable that when the airflow passes from the front of the vehicle and over the base body 1, the air guide surface 11 guides the airflow to flow on the upper and lower sides of the air guide surface 11. The curved surface of the concave air passage forces the airflow to conform to the concave path, bending downwards relative to the straight flow of the flat spoiler. The height of the air passage in the concave area is less than the corresponding height of the flat spoiler. Compared with the flat spoiler, it forms a local cross-sectional area contraction. According to Bernoulli's principle, the airflow velocity is forced to increase when passing through, resulting in a decrease in the pressure inside the air passage. Above the concave air passage, the airflow has a longer path and a slower velocity due to its detour around the edge of the protruding air guide, forming a relatively high-pressure area. Inside the concave air passage, that is, between the air guide surface 11 and the first air passage wall 21 and between the air guide surface 11 and the second air passage wall 31, the airflow velocity increases due to the cross-sectional area contraction, forming a local low-pressure area. The high-pressure area points to the low-pressure area, generating a suction force perpendicular to the air guide surface 11, that is, a downward pressure component.

[0053] When a vehicle is traveling at high speed, the airflow over the roof is fast and has low pressure, while the airflow under the vehicle is slow and has high pressure. The pressure difference between the roof and the undercarriage generates upward lift, which reduces tire grip and stability. A flat spoiler creates a vortex zone above the roof and a separated flow below by blocking the airflow over the roof, generating downforce through the pressure difference. However, the severe airflow separation can increase drag. The low pressure of the concave air passage extends the low-pressure zone over the roof. Guided by the curved surface, the airflow remains attached to this area. Compared to the vortex low-pressure zone of the flat spoiler, the low pressure is stronger and more evenly distributed. The low pressure in the concave air passage and the high pressure under the vehicle create a vertical pressure gradient across the vehicle body, generating downward net pressure that directly counteracts the lift caused by the pressure difference between the roof and the undercarriage. The increased downforce lowers the vehicle's center of gravity, resulting in a closer contact between the tires and the ground, significantly improving grip. When the vehicle is traveling at high speed, it can maintain a stable posture, reducing the risk of body swaying or loss of control caused by lift, and providing strong protection for driving safety. The concave air passage accelerates airflow and reduces local pressure, generating downward pressure to counteract the lift of the whole vehicle, making the body more stable and close to the ground, reducing airflow separation and turbulence caused by lift, thereby reducing wind resistance. The increased downforce optimizes the body posture and airflow adhesion, both suppressing vehicle lift and delaying airflow separation at the rear, achieving the dual effect of stability and reduced wind resistance.

[0054] In short, by setting the first air duct wall 21 and the second air duct wall 31 at an angle away from each other in the direction close to the air guide surface 11, a first concave air duct 22 and a second concave air duct 32 are formed between the first air duct wall 21 and the air guide surface 11, respectively. Above the concave air duct, the airflow has a longer path and a slower flow rate due to the circumference of the protruding air guide edge, forming a relatively high-pressure area. Inside the concave air duct, that is, between the air guide surface 11 and the air duct wall, the airflow speed is increased due to the contraction of the cross-sectional area, forming a local low-pressure area. The high-pressure area points to the low-pressure area, generating a suction force perpendicular to the air guide surface 11, that is, a downward pressure component, which counteracts the lift caused by the air pressure difference between the roof and the bottom of the vehicle, making the vehicle body more stable and closer to the ground, reducing airflow separation and vortices caused by lift, thereby reducing wind resistance.

[0055] According to some embodiments of the present application, a spoiler assembly 100 for a vehicle has a first windward wall 23 formed on the wall of the first air guide 2 facing the side of the vehicle's forward movement. The first windward wall 23 is connected to the first air passage wall 21 through a first inner side wall. The second air guide 3 has a second windward wall 33 formed on the wall of the second air guide 3 facing the side of the vehicle's forward movement. The second windward wall 33 is connected to the second air passage wall 31 through a second inner side wall. The first inner side wall and the second inner side wall are spaced apart in the vehicle width direction, and the first inner side wall and the second inner side wall are inclined towards each other in the direction towards the rear of the vehicle.

[0056] Understandably, the first and second inner sidewalls are inclined towards the rear of the vehicle and close to each other. When the vehicle is moving, the oncoming airflow is guided from the windward wall to the two surfaces of the inner sidewalls. The inclination angle causes the airflow to split to the sides and rear, guiding the airflow into the concave air passages. The first windward wall 23 connects to the first air passage wall 21 through the first inner sidewall, and the second windward wall 33 connects to the second air passage wall 31 through the second inner sidewall. More airflow enters the first and second concave air passages 22 and 32. According to Bernoulli's principle, a larger contact area and a longer contact time allow the airflow to accelerate more fully, thus creating a lower pressure within the air passages. The increased pressure difference directly increases the downward suction, generating stronger downforce, more effectively counteracting the lift during vehicle movement, and improving the vehicle's grip and stability.

[0057] The airflow is guided systematically from the windward wall, accelerating along the concave curved surface. This reduces premature separation of airflow due to abrupt changes. Compared to flat spoilers or vertical windward structures, this design pushes the separation point between the airflow and the spoiler assembly 100 rearward, reducing the vortex region behind the spoiler assembly 100. A smaller vortex region means a lower pressure difference between the front and rear of the vehicle, effectively reducing pressure drag and turbulence. The tilt angle and symmetrical arrangement of the windward wall create a stable and symmetrical flow field on both sides of the vehicle. This stable flow field further prevents turbulence and reduces energy loss caused by turbulence. Simultaneously, the symmetrical airflow distribution helps reduce vortex intensity around the vehicle. Vortex intensity is directly related to induced drag; a lower vortex intensity means lower induced drag, ultimately reducing overall vehicle drag.

[0058] According to some embodiments of this application, a spoiler assembly 100 for a vehicle has a first air-lifting protrusion 24 formed on a first windward wall 23. The first air-lifting protrusion 24 protrudes from the air-guiding surface 11, and the top surface of the first air-lifting protrusion 24 is connected to the top surface of the first air-guiding member 2. A second air-lifting protrusion 34 is formed on a second windward wall 33. The second air-lifting protrusion 34 protrudes from the air-guiding surface 11, and the top surface of the second air-lifting protrusion 34 is connected to the top surface of the second air-guiding member 3.

[0059] The first lifting bulge 24 and the second lifting bulge 34 protrude from the air guide surface 11. When the airflow passes through the first air guide 2 and the second air guide 3, the bulge structure divides the originally continuous airflow into upper and lower layers: the upper airflow is forced to rise upward due to the obstruction of the bulge and flows along the top surface of the bulge to the top of the first air guide 2 and the top of the second air guide 3 respectively; the lower airflow enters the concave air passage along the gap between the air guide surface 11 and the inner side of the bulge. When the upper airflow flows along the top surface of the bulge to the top of the air guide, the cross-sectional area of ​​the flow passage gradually shrinks due to the increase in the height of the bulge. According to Bernoulli's principle, the airflow velocity is forced to increase, forming a high-speed airflow layer. The induction effect generated by the high-speed airflow layer will drive the lower airflow to accelerate into the concave air passage, further enhancing the airflow acceleration effect of the concave air passage, making the low-pressure area in the air passage even lower, thereby generating stronger downforce and more effectively counteracting the lift force during vehicle movement.

[0060] According to some embodiments of this application, a spoiler assembly 100 for a vehicle has a first air-lifting protrusion 24 with a first transition concave surface 25 between the side of the first air-lifting protrusion 24 near the center of the base body 1 and the first air duct wall 21. The first transition concave surface 25 is recessed toward the rear of the vehicle, and the first inner sidewall is constructed as the first transition concave surface 25. A second air-lifting protrusion 34 with a second air duct wall 31 has a second transition concave surface 35 between the side of the second air-lifting protrusion 34 near the center of the base body 1 and the second air duct wall 31. The second transition concave surface 35 is recessed toward the rear of the vehicle, and the second inner sidewall is constructed as the second transition concave surface 35.

[0061] The first inner wall is constructed as a first transition concave surface 25, and the second inner wall is constructed as a second transition concave surface 35. The first transition concave surface 25 and the second transition concave surface 35 are recessed towards the rear of the vehicle. As the airflow flows from the airway wall to the concave airway, the concave surface provides a gradual curvature guide, and the airflow does not need to make a sharp turn, but naturally bends along the concave surface. This avoids the separation phenomenon caused by the sudden change in airflow direction, and avoids the formation of vortices due to inertia when the airflow encounters a right-angle turn. At the same time, the smooth transition of the arc surface maintains the adhesion state of the airflow and reduces energy loss.

[0062] like Figure 4 The diagram shown is an enlarged structural schematic of the second transition concave surface 35.

[0063] According to some embodiments of the present application, a spoiler assembly 100 for a vehicle has a first extension protrusion 26 formed on the outer side of a first air guide 2 extending toward the rear of the vehicle, the first extension protrusion 26 having a gradually decreasing cross-section in the direction toward the rear of the vehicle; and a second extension protrusion 36 formed on the outer side of a second air guide 3 extending toward the rear of the vehicle, the second extension protrusion 36 having a gradually decreasing cross-section in the direction toward the rear of the vehicle.

[0064] The first extended protrusion 26 and the second extended protrusion 36 extend towards the rear of the vehicle, and their cross-sections gradually decrease. When the vehicle is in motion, the oncoming airflow comes into contact with the extended protrusions. The gradually narrowing structure forces the airflow to diffuse laterally to both sides of the vehicle, preventing the airflow from converging behind the spoiler assembly 100 to form a large low-pressure vortex area. This makes the airflow more evenly distributed on both sides of the vehicle, reducing turbulence and energy loss caused by concentrated airflow. At the same time, the shape of the first extended protrusion 26 and the second extended protrusion 36 extending towards the rear of the vehicle and having a gradually narrowing cross-section presents a sporty shape. Through the transition of the cut surface and the connection of the curved surface, it gives the vehicle a sense of movement and visual impact, providing the vehicle with an aesthetic appeal.

[0065] In some embodiments of this application, a first rear windshield bracket 261 is also provided between the first extended protrusion 26 and the vehicle body. One side of the first rear windshield bracket 261 is connected to the first extended protrusion 26, and the other side is connected to the vehicle body, providing an additional stress point for the first extended protrusion 26 and preventing vibration of the first extended protrusion 26 during vehicle operation due to its extension toward the rear of the vehicle. A second rear windshield bracket 361 is also provided between the second extended protrusion 36 and the vehicle body. Two sides of the second rear windshield bracket 361 are connected to the second extended protrusion 36, and the other two sides are connected to the vehicle body, providing an additional stress point for the second extended protrusion 36 and preventing vibration of the second extended protrusion 36 during vehicle operation due to its extension toward the rear of the vehicle.

[0066] According to some embodiments of this application, a spoiler assembly 100 for a vehicle has a first air guide 2 and a second air guide 3 constructed as separate parts, and a base body 1 is connected to the first air guide 2 and the second air guide 3 respectively by fasteners 9.

[0067] The first air guide component 2, the second air guide component 3, and the base body 1 adopt a separate design. Compared with an integrated molding structure, molds can be developed separately for the complex curved surface features of different components. Intricate structures such as the first concave air passage 22, the second concave air passage 32, the first extended protrusion 26, and the second extended protrusion 36 can be manufactured with high precision using independent molds. The wide planar portion of the base body 1 can be produced using large standardized molds, reducing the design difficulty and manufacturing cost of a single mold. In addition, separate production allows for differentiated processes for different components, further optimizing production efficiency. At the same time, the fastener 9 connection method makes the component assembly process more controllable. During installation, the base body 1 is first fixed to the vehicle body, and then the first air guide component 2 and the second air guide component 3 are installed separately. The position is adjusted by fastener 9. Meanwhile, the separate design reduces the risk of bumps and knocks during the handling and installation of large components, and reduces the workload of operators.

[0068] According to some embodiments of this application, a spoiler assembly 100 for a vehicle has a base body 1 with a first connecting plate 12 and a second connecting plate 13 at both ends, the width of which gradually decreases outwards. The rear edge of the first connecting plate 12 is provided with a first fixing part 121, which is directly opposite to and engaged with at least a portion of the first air guide 2 in the thickness direction. The rear edge of the second connecting plate 13 is provided with a second fixing part 131, which is directly opposite to and engaged with at least a portion of the second air guide 3 in the thickness direction.

[0069] The width of the first connecting plate 12 and the second connecting plate 13 at both ends of the base body 1 gradually decreases outward. Sufficient width is maintained at the base where the stress is greater to ensure strength, while the outer side where the stress is less is gradually thinned to avoid the accumulation of redundant materials. Thus, the weight is effectively reduced without affecting the load-bearing capacity of key parts.

[0070] The rear edge of the first connecting plate 12 is provided with a first fixing part 121, and the rear edge of the second connecting plate 13 is provided with a second fixing part 131. The first fixing part 121 and the first air guide 2, and the second fixing part 131 and the second air guide 3 are directly engaged in the thickness direction. It can be understood that the engaging structure restricts the vertical displacement of the first air guide 2 and the second air guide 3, preventing the first air guide 2 or the second air guide 3 from loosening or tilting under the impact of high-speed airflow, ensuring that the airflow guidance path between the concave air passage and the windward wall remains stable, and at the same time restricting the lateral offset of the first air guide 2 and the second air guide 3, avoiding airflow turbulence caused by the asymmetrical displacement of the air guides on both sides, maintaining the consistency of the aerodynamic performance of the whole vehicle. At the same time, the engaging structure does not require additional fastening tools, and the connection between the air guide and the base body 1 can be completed by pressing or sliding, which can significantly reduce assembly time and improve production efficiency.

[0071] According to some embodiments of this application, a spoiler assembly 100 for a vehicle includes a base body 1 comprising: an inner body plate 14 adapted to be fixed to the vehicle body, wherein a first fixing portion 121 and a second fixing portion 131 are respectively provided on both sides of the width of the inner body plate 14; and an outer body plate 15, which cooperates with the inner body plate 14 in the thickness direction, wherein the first fixing portion 121 and the second fixing portion 131 protrude from the edge of the outer body plate 15.

[0072] The inner panel 14 and the outer panel 15 mate in the thickness direction, breaking down the installation process of the base body 1 into two independent steps. First, the inner panel 14 can be fixed to the vehicle body through the mounting holes or connecting structures on it. Utilizing the large contact area between the inner panel and the vehicle body, the accuracy of the installation position is ensured. Subsequently, the outer panel 15 is assembled with the inner panel. This step-by-step assembly method reduces assembly difficulty, improves assembly efficiency and product consistency. At the same time, the double-layer structure formed by the inner panel 14 and the outer panel 15 disperses the airflow force, preventing deformation or breakage of a single panel due to excessive stress, and significantly improving the overall rigidity and durability of the base body 1.

[0073] The first fixing part 121 and the second fixing part 131 protruding from the edge of the outer plate 15 of the main body can provide a larger contact area and stronger connection strength. When connected with the first air guide 2 and the second air guide 3, the larger contact area means a more uniform distribution of connection force and reduces stress concentration. The protruding fixing part can accommodate longer bolts, more bolts, or more or larger snap-fit ​​parts, thereby improving the tightness of the connection and ensuring that the connection between the base body 1 and other components remains stable in complex airflow environments.

[0074] According to some embodiments of this application, a spoiler assembly 100 for a vehicle includes a first air guide 2 comprising a first inner air guide plate 27 and a first outer air guide plate 28, wherein the first inner air guide plate 27 and the first outer air guide plate 28 are configured to cooperate in the thickness direction, the bottom of the first outer air guide plate 28 forms a first mounting area that cooperates with a first fixing part 121, and the first inner air guide plate 27 forms a first clearance notch 271 that avoids the first mounting area; a second air guide 3 comprises a second inner air guide plate 37 and a second outer air guide plate 28, wherein the second inner air guide plate 37 and the second outer air guide plate 28 are configured to cooperate in the thickness direction, the bottom of the second outer air guide plate 28 forms a second mounting area that cooperates with a second fixing part 131, and the second inner air guide plate 37 forms a second clearance notch 371 that avoids the second mounting area.

[0075] It is understandable that the double-layered first air guide 2 and second air guide 3 have the same beneficial effects on installation and structural strength as the double-layered base body 1, both reducing assembly difficulty and improving structural strength. Simultaneously, the inner and outer plates of the air guides can be designed with curved surfaces, forming a more aerodynamic and streamlined shape through their cooperation. The outer plate, as the direct contact surface with the airflow, can be a smooth, streamlined curved surface to guide the airflow evenly. The inner plate can be designed with internal reinforcing ribs or guide grooves to assist the outer plate in controlling the airflow path. The clearance notches prevent airflow interference with the first air guide 2 and the second air guide inner plate 37, ensuring the continuity and smoothness of the outer plate surface. The clearance notches also ensure a smooth transition at the connection between the outer plate and the fixing part, allowing airflow to flow smoothly, maintaining a stable flow field around the vehicle, indirectly reducing additional resistance caused by airflow disturbance, and simultaneously reducing aerodynamic noise and improving driving comfort.

[0076] According to some embodiments of this application, a spoiler assembly 100 for a vehicle further includes: a camera shield 4 and a camera 41. The camera shield 4 is disposed on the base body 1 and protrudes from the air guide surface 11. The width of the camera shield 4 gradually decreases in the direction away from the air guide surface 11. An accommodating space is formed inside the camera shield 4, and at least a portion of the camera 41 is accommodated in the accommodating space.

[0077] The camera shield 4 protrudes from the air guide surface 11, making the installation position of the camera 41 higher than other parts of the vehicle. This effectively avoids blind spots caused by obstruction of vision due to the vehicle body structure. The protruding camera 4 can capture obstacles at lower positions behind the vehicle, improving the coverage of the panoramic imaging system and enhancing driving safety. The tapered shape of the camera shield 4 conforms to aerodynamic principles. When airflow passes through the camera 4, the gradually narrowing contour guides the airflow to a smooth transition, avoiding airflow separation caused by right angles or abrupt changes in cross-section, and reducing the additional wind resistance caused by the protrusion of the camera shield 4. At the same time, the relative position and shape of the camera shield 4 and the air guide surface 11 can form a synergistic airflow guiding effect with the surrounding first air guide component 2 and second air guide component 3, further optimizing the overall vehicle airflow field.

[0078] In some embodiments of this application, the camera protective cover 4 is provided with a buckle 5 and a connecting rib, and the main body outer plate 15 is provided with a clearance hole 151 suitable for avoiding the camera protective cover 4. The buckle 5 and the connecting rib respectively cooperate with the hole wall of the clearance hole 151 to realize the connection between the camera protective cover 4 and the main body outer plate 15. The camera protective cover 4 is also provided with a scratch-resistant part 42, which can be constructed as a sponge. The scratch-resistant part 42 is located on the buckle 5 side of the camera protective cover 4 to prevent scratching the main body outer plate 15 during installation. By pre-installing the camera 4 on the base body 1 through the camera protective cover 4, it is possible to avoid making an additional mold for the main body outer plate 15 and the camera protective cover 4 as one piece, thereby reducing costs.

[0079] In some other embodiments of this application, the inner panel 14 and the outer panel 15 of the main body are fixed together as a whole by double-sided adhesive tape 6 and screws. At the same time, multiple buckles 5 are provided to strengthen the connection between the inner panel and the outer panel. The buckles 5 are set on the inner panel 14 by bolts. The corresponding part of the outer panel 15 is provided with a groove that cooperates with the buckles 5. When assembling the base body 1, the base body 1 is fixed to the tailgate sheet metal of the vehicle.

[0080] The inner and outer panels of the first air guide inner plate 27 and the first air guide outer plate 28 are fixed together as a whole by double-sided tape 6, screws, and clips 5. The inner and outer panels of the second air guide inner plate 37 and the second air guide outer plate 28 are also fixed together as a whole by double-sided tape 6, screws, and clips 5. In addition to being fixed by double-sided tape 6 and screws, the inner and outer panels of the first air guide 2 and the second air guide 3 are also provided with flanged sections 281. The flanged sections 281 are located on the edge of the outer plate, and the corresponding part of the inner plate is provided with ribs 272. The flanged parts cooperate with the ribs 272 to further strengthen the connection strength between the inner and outer plates.

[0081] The buckle 5 has two structural forms: double-headed buckle 5 and single-headed buckle 5. The double-headed buckle 5 can provide higher connection strength, while the single-headed buckle 5 can occupy less area while providing connection strength.

[0082] In some other embodiments of this application, an edge sealing strip 8 is also included, which is disposed at least partially on the edge of the spoiler assembly 100 to cover the gap between the spoiler assembly 100 and the vehicle body.

[0083] In some other embodiments of this application, vibration damping pads 7 are provided between the first air guide 2 and the base body 1, between the second air guide 3 and the base body 1, between the first air guide 2 and the vehicle body, between the second air guide 3 and the vehicle body, and between the base body 1 and the vehicle body. The vibration damping pads 7 are constructed as sponge pads. Vibration damping pads can prevent vibration between structures, improve the lifespan of the spoiler assembly 100, and reduce noise caused by structural vibration when the vehicle is in motion.

[0084] The vehicle according to an embodiment of this application is briefly described below.

[0085] The vehicle according to the embodiments of this application includes the spoiler assembly 100 described in any of the above embodiments. Since the vehicle according to this embodiment is equipped with the spoiler assembly 100 described in any of the above embodiments, the vehicle according to the embodiments of this application has lower wind resistance. For new energy vehicles, the reduction in wind resistance directly reduces driving power consumption and can increase the driving range with the same battery capacity. For fuel vehicles, it can reduce fuel consumption and improve economy. At the same time, the symmetrical first concave air passage 22 and the second concave air passage 32 form a low-pressure area on the roof through the Bernoulli effect, generating downward additional pressure, effectively offsetting the lift generated by the air pressure difference between the roof and the bottom of the vehicle when the vehicle is driving at high speed, suppressing the lift of the vehicle body, increasing the tire ground load, improving grip, and reducing the risk of sideslip. The symmetrically arranged air guides guide the airflow to flow orderly along the concave air passages, delaying the separation of the rear airflow, reducing turbulence interference around the vehicle body, which can significantly reduce the lateral deviation of the vehicle, making the driving posture more stable and the handling response more precise.
