Description

Technical Field

[0001] The present application relates to the field of automobile technology, and in particular to a spoiler device and an automobile. Background Art

[0002] The wind resistance index of a car directly affects the fuel consumption or power consumption of the car. Reducing the wind resistance of the car can save fuel or power and improve the endurance of the car.

[0003] Conventional automobiles are usually provided with different spoiler structures at various locations on the automobile body, wherein the spoiler structure provided at the rear of the automobile is usually called a spoiler. Some conventional spoilers have poor ability to reduce wind resistance. Utility Model Content

[0004] The present application provides a spoiler device and a car to solve the technical problem that some existing tail wings have poor ability to reduce wind resistance.

[0005] The embodiment of the present application is implemented as follows:

[0006] In the first aspect, the present application provides a spoiler device, including a first spoiler, the first spoiler including a main body and a warped portion, the main body including a first edge and a second edge arranged opposite to each other along its width direction, and a first surface and a second surface arranged opposite to each other along its thickness direction; in the length direction of the main body, the middle part of the first edge is concavely arranged toward the side close to the second edge; the warped portion is arranged at the middle part of the first surface on the side close to the second edge, the warped portion has a third surface, the third surface is obliquely intersected with the first surface, and the third surface is inclined and warped in a direction away from the second edge on a side away from the first edge.

[0007] During the forward movement of the automobile, the airflow flows from the first edge toward the second edge, and most of the airflow is concentrated in the middle of the rear of the vehicle body. After the warping portion is additionally provided in the middle of the main body, the warping portion can further play a role in disturbing the airflow, so as to further reduce the vortex formed by the airflow on the side of the second edge of the main body, thereby playing a role in reducing the wind resistance of the rear of the automobile, thereby improving the endurance of the automobile. The third surface intersects with the first surface obliquely, so that the airflow pressure on the side of the second surface of the main body is less than the airflow pressure on the side of the first surface of the main body, and a pressure difference is generated between the first surface and the second surface of the main body, thereby forming a downward pressure on the main body, and the downward pressure can reduce the overall lift of the rear of the vehicle body during high-speed operation, so as to improve the running stability of the automobile. The warping portion additionally provided in the middle of the main body can also improve the strength and stability of the main body, ensure that the first spoiler has a strong pressure-bearing capacity, and can bear a large downward pressure, thereby improving the anti-deformation ability of the first spoiler, thereby ensuring its effect of reducing wind resistance.

[0008] At the same time, when most of the airflow in the middle part contacts the first edge, the concave first edge can disperse the airflow, further reducing the wind resistance caused by the airflow to the car. The arc-shaped concave first edge can also beautify the appearance of the spoiler. In addition, the narrow width of the two ends of the main body along its length direction can also reduce the wind resistance, reduce the overall weight of the main body, and reduce the material cost of the first spoiler.

[0009] In one possible implementation:

[0010] The first spoiler includes a first cover plate and a second cover plate, the first cover plate covers the second cover plate and encloses a hollow cavity, the edge of the first cover plate is connected to the edge of the second cover plate; the surface of the first cover plate facing away from the second cover plate is the first surface, the surface of the second cover plate facing away from the first cover plate is the second surface, and the warped portion is provided on the first cover plate.

[0011] In one possible implementation:

[0012] In the width direction of the main body, the cross section of the main body perpendicular to the length direction of the main body is wide in the middle and narrow at both ends.

[0013] In one possible implementation:

[0014] The first surface is a plane, and the second surface is an arc surface convex outwardly along the width direction of the main body.

[0015] In one possible implementation:

[0016] The main body further comprises a supporting portion, which is protruding from the second surface of the second cover plate, and an end of the supporting portion away from the main body is used for connecting with a vehicle body.

[0017] In one possible implementation:

[0018] The warped portion further has an arc transition surface, and the third surface is connected to the second surface via the arc transition surface.

[0019] In one possible implementation:

[0020] The spoiler device further comprises two second spoilers, and the two second spoilers are respectively connected to two ends of the main body along the length direction thereof.

[0021] In one possible implementation:

[0022] In the width direction of the main body, the second spoiler is wide in the middle and pointed at both ends.

[0023] In one possible implementation:

[0024] The second spoiler is in the shape of a plate, the main body is connected to the plate surface of the second spoiler, the second spoiler is inclined relative to the first surface, the angle between the plate surface of the second spoiler and the first surface is an acute angle, and the angle between the second spoiler and the second edge is an acute angle.

[0025] In a second aspect, the present application provides an automobile, comprising a vehicle body and the aforementioned spoiler, wherein the spoiler is connected to the vehicle body, and a first surface of the spoiler obliquely intersects with a horizontal plane.

When an element is considered to be "set on" another element, it may be directly set on the other element or there may also be a centered element. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0054] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present application. The terms used herein in the specification of the present application are only for the purpose of describing specific embodiments and are not intended to limit the present application. The term "or / and" used herein includes any and all combinations of one or more related listed items.

[0055] Some embodiments of the present application are described in detail. In the absence of conflict, the following embodiments and features of the embodiments can be combined with each other.

[0056] Example

[0057] See also Figures 1 to 4 The present embodiment provides a spoiler 100, comprising a first spoiler 10, the first spoiler 10 comprising a main body 20 and a warping portion 30, the main body 20 comprising a first edge 21a and a second edge 21b disposed opposite to each other along its width direction Y, and a first surface 22a and a second surface 22b disposed opposite to each other along its thickness direction Z. In the length direction X of the main body 20, the middle portion of the first edge 21a is concavely disposed toward the side close to the second edge 21b. The warping portion 30 is disposed at the middle portion of the first surface 22a near the second edge 21b, and the warping portion 30 has a third surface 31, the third surface 31 obliquely intersects with the first surface 22a, and the third surface 31 is away from the side of the first edge 21a, and is tilted and warped toward the side away from the first surface 22a.

[0058] When the spoiler 100 of this embodiment is installed at the rear portion 202 of the vehicle body 201, the main body 20 is connected to the vehicle body 201 (see FIG. Fig.19 and Fig. 20), the second surface 22b is spaced apart from the vehicle body 201 along the thickness direction Z of the main body 20, the first surface 22a is located on the side of the second surface 22b away from the vehicle body 201, the first surface 22a is obliquely intersected with the horizontal plane, and the second edge 21b is located above and behind the first edge 21a.

[0059] When the automobile 200 moves forward, the airflow flows from the first edge 21a to the second edge 21b, and most of the airflow is concentrated in the middle of the rear portion 202 of the vehicle body 201 (see Fig.21 ). By making the first surface 22a and the horizontal plane intersect at an angle, the airflow can be disturbed. After the warping portion 30 is additionally provided in the middle of the main body 20, the warping portion 30 can further disturb the airflow, so as to further reduce the vortex formed by the airflow on the side of the second edge 21b of the main body 20, thereby reducing the wind resistance of the tail 202 of the automobile 200, and thus improving the endurance of the automobile 200. The third surface 31 intersects with the first surface 22a at an angle, so that the airflow pressure on the side of the second surface 22b of the main body 20 is less than the airflow pressure on the side of the first surface 22a of the main body 20, and a pressure difference is generated between the first surface 22a and the second surface 22b of the main body 20, thereby forming a downward pressure on the main body 20, and the downward pressure can reduce the overall lift of the tail 202 of the vehicle body 201 during high-speed operation, so as to improve the running stability of the automobile 200.

[0060] The additional raised portion 30 in the middle of the main body 20 can also improve the strength and stability of the main body 20, ensuring that the first spoiler 10 has a strong pressure-bearing capacity and can bear a large downforce, thereby improving the first spoiler 10's anti-deformation ability and further ensuring its effect of reducing wind resistance.

[0061] At the same time, when most of the airflow in the middle contacts the first edge 21a, the concave first edge 21a can disperse the airflow, further reducing the wind resistance of the airflow to the car 200. The arc-shaped concave first edge 21a can also beautify the appearance of the spoiler 100.

[0062] In addition, the width of the two ends of the main body 20 along the length direction X is relatively narrow, which can also reduce wind resistance, reduce the overall weight of the main body 20 , and reduce the material cost of the first spoiler 10 .

[0063] In this embodiment, see Figure 4The angle between the first surface 22a and the third surface 31 is an acute angle, which is greater than 0.5° and less than 3°. For example, the angle can be set to any one of 0.5°, 1°, 1.5°, 2°, 2.5°, and 3°. If the angle is too small, the warped portion 30 cannot further play a spoiler role. If the angle is too large, the warped portion 30 has a limited effect on reducing wind resistance. In other embodiments, according to the design requirements of different spoiler devices 100, the angle can also be adaptively adjusted.

[0064] In this embodiment, see Figure 4 When the first spoiler 10 is installed on the vehicle body 201, the angle between the first surface 22a and the horizontal plane can be set to between 12° and 15°. For example, the angle can be set to any one of 12°, 13°, 14° or 15°.

[0065] The angle between the second surface 22b and the horizontal plane may be set to be between 23° and 27°. For example, the angle may be set to any one of 23°, 24°, 25°, 26° or 27°.

[0066] In other embodiments, the angle between the first surface 22a and the horizontal plane, and the angle between the second surface 22b and the horizontal plane may also be adjusted according to actual needs.

[0067] In this embodiment, see Figure 3 The ratio of the width of the main body 20 at the position where the warping portion 30 is provided to the minimum width at both ends of the main body 20 can be set to between 1.4 and 1.6 to ensure the overall strength of the main body 20. For example, the ratio can be set to 1.4, 1.5 or 1.6.

[0068] In this embodiment, see Figures 4 to 6 The first spoiler 10 includes a first cover plate 23 and a second cover plate 24. The first cover plate 23 covers the second cover plate 24 to form a hollow cavity Q. The edge of the first cover plate 23 is connected to the edge of the second cover plate 24. The surface of the first cover plate 23 away from the second cover plate 24 is the first surface 22a, and the surface of the second cover plate 24 away from the first cover plate 23 is the second surface 22b. The warping portion 30 is provided on the first cover plate 23.

[0069] In this embodiment, the first cover plate 23 and the second cover plate 24 are respectively injection molded parts. In other embodiments, the materials of the first cover plate 23 and the second cover plate 24 can also be set to various materials such as fiberglass, aluminum alloy, carbon fiber, etc.

[0070] In this embodiment, in the width direction Y of the main body 20 , the cross section of the main body 10 perpendicular to the length direction X of the main body 20 is wide in the middle and narrow at both ends.

[0071] In this way, the main body 20 can separate the airflow at one end in the width direction Y, so that the airflow velocities on both sides of the first cover plate 23 and the second cover plate 24 are different, thereby forming a pressure difference and generating downward pressure on the main body 20 as a whole. The main body 20 can disrupt the vortex at the other end in the width direction Y, thereby reducing the wind resistance.

[0072] In this embodiment, see Figure 5 and Figure 6 The first surface 22a is generally flat, and the second surface 22b is an arc surface that is convex away from the first surface 22a, so as to form a shape that is wide in the middle and narrow at both ends.

[0073] In this way, the air flow velocity on the first surface 22a side is smaller than the air flow velocity on the second surface 22b side, thereby increasing the pressure difference between the first surface 22a and the second surface 22b of the main body 20, thereby increasing the downward pressure exerted by the air flow on the first spoiler 10 in the direction of gravity, thereby improving the driving stability of the automobile 200.

[0074] In this embodiment, see Figure 4 A circular arc transition surface 32 is provided on one side where the raised portion 30 is connected to the second cover plate 24. The circular arc transition surface 32 can improve the turbulence performance of the raised portion 30 to further reduce wind resistance.

[0075] In this embodiment, see Figure 5 and Figure 6 The first cover plate 23 is provided with a first clamping portion 251 , and the second cover plate 24 is provided with a second clamping portion 252 . The first clamping portion 251 is clamped with the second clamping portion 252 .

[0076] In this way, the installation of the first cover plate 23 and the second cover plate 24 can be positioned to improve the assembly reliability of the first cover plate 23 and the second cover plate 24 .

[0077] In this embodiment, see Figure 7 The second clamping portion 252 is disposed on one side of the second cover plate 24 close to the second edge 21b. A plurality of second clamping portions 252 are provided, and the plurality of second clamping portions 252 are spaced apart along the length direction X of the main body 20. The number and position of the first clamping portions 251 are corresponding to the number and position of the second clamping portions 252.

[0078] Alternatively, see Figure 7 There are three second clamping portions 252 , wherein two second clamping portions 252 are located at two ends of the second cover plate 24 , and another second clamping portion 252 is located in the middle of the second cover plate 24 .

[0079] In other embodiments, the number and position of the second clamping portions 252 may be adjusted according to actual needs, and this application does not specifically limit them.

[0080] In this embodiment, see Figure 6 and Fig.11 The first clamping portion 251 is a clamping protrusion 251a, and the second clamping portion 252 includes a clamping block 252a, and the clamping block 252a is provided with a first clamping groove 252b, and the clamping protrusion 251a is clamped in the first clamping groove 252b. In other embodiments, the first clamping portion 251 can also be set as a convex column, and the second clamping portion 252 can be set as a plug hole.

[0081] In this embodiment, see Figures 7 to 9 A first welding portion 253 is provided on a surface of the second cover plate 24 facing the first cover plate 23 , and the first welding portion 253 is welded to the surface of the first cover plate 23 .

[0082] The first cover plate 23 and the second cover plate 24 are welded and connected by the first welding portion 253, which can not only ensure the stable connection between the first cover plate 23 and the second cover plate 24, but also support the second cover plate 24 to form a stable hollow cavity Q between the first cover plate 23 and the second cover plate 24, thereby reducing the possibility of deformation of the first spoiler 10 under pressure and extending the service life of the spoiler device 100.

[0083] In other embodiments, the first welding portion 253 may also be disposed on the first cover plate 23 .

[0084] In other embodiments, according to the different materials of the first cover plate 23 and the second cover plate 24 , the first cover plate 23 and the second cover plate 24 may also be assembled by a connection structure such as screws or rivets.

[0085] Alternatively, see Figure 7 The first welding portion 253 includes two welding bosses 254, which are respectively arranged on both sides of the second cover plate 24 along the width direction Y, one welding boss 254 extends along the first edge 21a, and the other welding boss 254 extends along the second edge 21b.

[0086] In this embodiment, see Figures 8 to 10 The main body 20 further includes a supporting portion 26 , which is protruding from the second surface 22 b of the second cover plate 24 , and an end of the supporting portion 26 away from the main body 20 is used for connecting to the vehicle body 201 .

[0087] By connecting the support portion 26 to the vehicle body 201, the first spoiler 10 can be installed on the vehicle body 201, and a gap can be formed between the main body 20 and the vehicle body 201 to avoid a dead angle area at the connection between the first spoiler 10 and the vehicle body 201, thereby avoiding the accumulation of foreign matter at the spoiler 100, thereby ensuring that the spoiler 100 can reliably reduce wind resistance.

[0088] In other embodiments of the present application, the second cover plate 24 may not be provided with the support portion 26, and the main body 20 is connected to the vehicle body 201 through an independent support structure. The independent support structure can be set as a support column, and the two ends of the support column can be connected to the second cover plate 24 and the vehicle body 201 respectively through a fastening structure such as a bolt. Therefore, there are many ways to connect the spoiler 100 of this embodiment to the vehicle body 201, and the embodiment of the present application does not specifically limit them.

[0089] In this embodiment, see Fig.10 The support part 26 includes a panel 261 and a bottom plate 262. The panel 261 encloses a cavity with one side open. One end of the panel 261 is connected to the second cover plate 24, and the other end of the panel 261 is connected to the bottom plate 262. The bottom plate 262 can be arranged on the end surface or in the cavity of the panel 261. The support part 26 also includes a fastener 28, which is connected to the bottom plate 262 and connected to the vehicle body 201.

[0090] The structure of the enclosure 261 and the bottom plate 262 can be easily integrated with the second cover plate 24. For example, the second cover plate 24 with the support portion 26 can be integrally formed by injection molding, thereby reducing the processing steps of the first spoiler 10, improving the production efficiency of the first spoiler 10, and reducing the assembly steps of the first spoiler 10.

[0091] In this embodiment, see Figure 6 and Fig.10 The support portion 26 further includes a first reinforcement structure 263, which is disposed in the enclosure 261 and is used to reinforce the enclosure 261, thereby improving the strength of the support portion 26. The first reinforcement structure 263 can be specifically configured as a reinforcement rib or a reinforcement convex column connected to the enclosure 261.

[0092] In this embodiment, see Fig.10 The supporting portion 26 further includes a sealing plate 265 , which can be detachably covered on the opening of the cavity, so that foreign matter can be prevented from entering the cavity, thereby ensuring the overall airtightness of the first spoiler 10 .

[0093] In this embodiment, see Figure 8 A connecting opening 241 is provided at the connection between the second cover plate 24 and the surrounding plate 261 , and a first buckle 266 a is provided at one end of the sealing plate 265 close to the second cover plate 24 , and the first buckle 266 a is engaged in the connecting opening 241 .

[0094] At one end of the support portion 26 away from the second cover plate 24 , a second slot 2611 is provided on the inner surface of the enclosure 261 , and a second buckle 266 b is provided at one end of the sealing plate 265 away from the second cover plate 24 . The second buckle 266 b extends into the cavity and engages with the second slot 2611 .

[0095] In this way, the first buckle 266a is engaged with the communication port 241, and the second buckle 266b is engaged with the second slot 2611, so that the sealing plate 265 and the surrounding plate 261 can be reliably and quickly engaged, thereby improving the assembly efficiency of the second cover plate 24 and the sealing plate 265. In other embodiments, the sealing plate 265 can also be connected to the surrounding plate 261 through a locking structure.

[0096] In this embodiment, see Fig.10 There are two second buckles 266b, and the two second buckles 266b are spaced apart along the length direction X of the main body 20. In this way, a three-point clamping connection is formed between the sealing plate 265 and the surrounding plate 261, further improving the connection reliability between the sealing plate 265 and the surrounding plate 261.

[0097] In this embodiment, see Fig. 9 A second reinforcing structure 264 is further provided on the surface of the second cover plate 24 facing the first cover plate 23 . The second reinforcing structure 264 is provided on one side of the supporting portion 26 and is used to reinforce the supporting portion 26 .

[0098] Optionally, the second reinforcement structure 264 is a mesh grille provided on the surface of the second cover plate 24, which can improve the connection strength between the support portion 26 and the second cover plate 24. In other embodiments, the second reinforcement structure 264 can also be provided as a plurality of reinforcement ribs.

[0099] In this embodiment, see Figure 7 The support portion 26 is divided into a first support portion 26a and two second support portions 26b. The first support portion 26a is arranged in the middle of the second cover plate 24 along its length direction X, and the two second support portions 26b are respectively located on both sides of the first support portion 26a. In other embodiments, the number of support portions 26 can also be adjusted according to actual installation requirements.

[0100] Specifically, the second cover plate 24 is provided with a communication port 241 at each of the three support portions 26, and the second cover plate 24 is provided with a second reinforcement structure 264 at each of the two second support portions 26b. In other embodiments, the number and position of the communication port 241 and the second reinforcement structure 264 can be adjusted according to actual needs, and this application does not specifically limit them.

[0101] In another embodiment, see Figure 12 to Figure 14 The spoiler device 100 includes the aforementioned first spoiler 10 and two second spoilers 40 , and the two second spoilers 40 are respectively connected to the two ends of the main body 20 of the first spoiler 10 along the length direction X thereof.

[0102] The two second spoilers 40 can spoil the airflow at both ends of the main body 20, thereby enhancing the wind resistance reduction capability of the spoiler device 100. In addition, the two second spoilers 40 can also improve the aesthetics of the spoiler device 100 and enhance the user experience.

[0103] In this embodiment, see Fig.12 The second spoiler 40 is plate-shaped, the main body 20 is connected to the plate surface of the second spoiler 40, the second spoiler 40 is inclined relative to the first surface 22a, the angle between the plate surface of the second spoiler 40 and the first surface 22a is an acute angle, and the angle between the second spoiler 40 and the second edge 21b is an acute angle.

[0104] The second spoiler 40 has a first plate surface 41 a and a second plate surface 41 b . The first plate surface 41 a is located at a side of the second spoiler 40 close to the main body 20 , and the second plate surface 41 b is located at a side of the second spoiler 40 away from the main body 20 .

[0105] Through the above-mentioned structural arrangement, the second spoiler 40 can play a better role in disturbing the vortex, thereby reducing the wind resistance of the automobile 200 during driving.

[0106] The included angle between the second spoiler 40 and the second edge 21 b may be set to be between 1° and 5°. For example, the included angle may be set to any one of 1°, 2°, 3°, 4° or 5°.

[0107] In this embodiment, see Fig.12 and Fig.13 In the width direction Y of the main body 20, the second spoiler 40 is wide in the middle and pointed at both ends. In this way, when the spoiler 100 is installed on the vehicle body 201, the bottom edge of the second spoiler 40 is roughly horizontal, the windward tip of the second spoiler 40 can separate the airflow, and the leeward tip of the second spoiler 40 can disturb the vortex, thereby further reducing wind resistance.
