Description

Technical Field

[0001] This disclosure relates to the field of vehicle technology, and more specifically, to a vehicle rear wing and a vehicle. Background Technology

[0002] Vehicles are affected by wind resistance during operation, which impacts their driving performance. Some vehicles reduce wind resistance at high speeds by adding a rear wing, thereby improving the driving experience. A vehicle's rear wing operates in two main states: deployed (rising from the rear of the vehicle) and closed (descending to be flush with the rear). The noise sources during deployment and closure primarily originate from motor and structural vibrations, while during driving, the noise mainly comes from the friction generated by airflow cutting through the wing. The noise from the rear wing can radiate into the vehicle's interior through the body and airflow, causing annoyance and discomfort for passengers, especially in the rear seats.

[0003] In related technologies, research on vehicle rear wings focuses more on wind resistance and flow noise. The technology is mainly reflected in the design of the rear wing's curved surface and the mounting mechanism. The main technical point is to reduce airflow resistance, while ignoring the motor and structural noise radiation during the operation of the rear wing components, as well as the flow noise radiation generated by the rear wing when the car is traveling at high speed.

[0044] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0045] In this disclosure, unless otherwise stated, directional terms such as "upper" and "lower" generally refer to the upper and lower positions of the vehicle's rear wing in its normal operating state when mounted on the vehicle body. Since structures such as the drive module, mounting plate, airflow-guiding sound-absorbing plate, and vibration-damping sound-absorbing cover are all mounted on the lower surface of the rear wing, in order to clearly demonstrate these structures, [the following is omitted as it is not part of the main text]. Figure 1 , Figure 2 as well as Figures 9 to 14 In this disclosure, all structures are shown with their lower surfaces facing upwards. "Inner" and "outer" refer to the inner and outer dimensions relative to the contour of the corresponding component itself. The terms "first," "second," etc., used in this disclosure are for distinguishing one element from another and do not indicate any order or importance. Furthermore, when the following description relates to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0046] According to a specific embodiment of this disclosure, a vehicle rear wing is provided. The rear wing is mounted on the rear side of the vehicle body and is capable of raising and lowering relative to the vehicle body. (Refer to...) Figure 1 and Figure 2 As shown, the vehicle's rear wing may include a rear wing plate 100, a mounting plate 1, a drive module 2, a vibration damping and sound-absorbing cover 3, and a flow-guiding and sound-absorbing plate 4.

[0047] The mounting plate 1 can be fixedly connected to the lower surface of the rear wing 100; the drive module 2 can be fixedly connected to the lower surface of the mounting plate 1, so as to be assembled with the rear wing 100 through the mounting plate 1, and the drive module 2 is used to drive the rear wing 100 to rise and fall relative to the vehicle body; the vibration damping and sound absorbing cover 3 can be fixedly connected to the lower surface of the mounting plate 1, and can be covered on the outside of the drive module 2. Multiple vibration damping pads 31 can be provided on the inner sidewall of the vibration damping and sound absorbing cover 3, and the vibration damping pads 31 can abut against the drive module 2 to reduce the vibration of the rear wing 100. To mitigate the vibration of the moving module 2, the vibration damping and sound-absorbing cover 3 may further include multiple spaced first sound-absorbing micropores 32. The first sound-absorbing micropores 32 are through holes and are located on the side wall of the vibration damping and sound-absorbing cover 3 and the bottom wall away from the mounting plate 1. The flow-guiding sound-absorbing plate 4 may be fixedly connected between the tail fin plate 100 and the mounting plate 1. The interior of the flow-guiding sound-absorbing plate 4 may be provided with a sound-absorbing cavity 41. Multiple spaced second sound-absorbing micropores 42 may be provided on the cavity wall of the sound-absorbing cavity 41 away from the mounting plate 1. The second sound-absorbing micropores 42 are constructed as through holes.

[0048] Through the above technical solution, in the vehicle rear wing provided in this disclosure, the vibration damping and sound-absorbing cover 3 is installed on the outside of the drive module 2. This not only isolates the noise generated during the operation of the drive module 2 from the vehicle body, but also absorbs the noise radiation through multiple first sound-absorbing micropores 32, thereby improving the impact of the noise radiation on the passengers inside the vehicle. In addition, the vibration damping pads 31 inside the vibration damping and sound-absorbing cover 3 can fill the gap between the vibration damping and sound-absorbing cover 3 and the drive module 2, thereby reducing the vibration and noise generated by the drive module 2 during operation. The lower surface of the airflow guiding and sound-absorbing plate 4 located below the rear wing 100 is constructed as an arc surface to reduce the resistance of the vehicle rear wing cutting through the air, thereby reducing the airflow noise it generates. The multiple second sound-absorbing micropores 42 provided on the airflow guiding and sound-absorbing plate 4 can cooperate with the sound-absorbing cavity 41, thus absorbing the airflow noise generated by the rear wing 100 cutting through the air, and preventing excessive airflow from entering the sound-absorbing cavity 41.

[0049] In specific embodiments of this disclosure, in order to further improve the noise reduction and sound absorption effect of the vibration damping sound-absorbing cover 3 and the flow guiding sound-absorbing plate 4, sound insulation cotton (not shown) can also be laid on the outer or inner walls of both as needed.

[0050] refer to Figure 7 and Figure 8 As shown, in order to facilitate the assembly of the vibration damping pad 31 and the vibration damping and sound absorbing cover 3, a cross-shaped through groove 311 can be provided on the vibration damping pad 31. The cross-shaped through groove 311 includes a long groove and a short groove that are perpendicular to each other.

[0051] refer to Figures 3 to 6 As shown, the inner wall of the vibration damping and sound-absorbing cover 3 can be provided with a mounting bracket 37 for fixing the vibration damping pad 31. The mounting bracket 37 can include a support section 371 and a locking section 372 that are perpendicular to each other. The support section 371 extends from the inner wall of the vibration damping and sound-absorbing cover 3 toward the interior of the vibration damping and sound-absorbing cover 3 (i.e., toward the drive module 2) to support the vibration damping pad 31. The locking section 372 can be fixedly connected to the end of the support section 371 and extends perpendicular to the support section 371 to form a T-shaped structure with the support section 371. The length of the locking section 372 can be greater than the length of the short groove of the cross-shaped through groove 311 and less than the length of the long groove of the cross-shaped through groove 311. The width of the locking section 372 can be less than the width of the long groove of the cross-shaped through groove 311, so that the locking section 372 can pass through the long groove and stop on the outside of the short groove. Figure 8 The image shows the state when the locking section 372 of the mounting bracket 37 passes through the long groove on the damping pad 31. In this state, the damping pad 31 can be rotated 90° so that the locking section 372 stops on the outside of the short groove, thereby preventing the damping pad 31 from coming off the mounting bracket 37.

[0052] In a specific embodiment of this disclosure, the outer diameter of the vibration damping pad 31 can be 5mm, and it has a 2.5mm high protrusion inside. The protrusion has a cross-shaped through groove 311 of the same size. The length of the long groove can be 3mm, the length of the short groove can be 2mm, and the width of both the long and short grooves can be 1mm. The length of the locking section 372 of the mounting bracket 37 can be 2.9mm, and the width can be 0.9mm.

[0053] In a specific embodiment of this disclosure, a plurality of first sound-absorbing micropores 32 can be arranged at equal intervals. The diameter of the first sound-absorbing micropores 32 can be 1 mm to 1.5 mm, preferably 1.2 mm, and the spacing between two adjacent first sound-absorbing micropores 32 is 4 mm to 6 mm, preferably 5 mm.

[0054] In the specific embodiments of this disclosure, reference is made to Figure 9 and Figure 10 As shown, the drive module 2 may include a motor 21, a gearbox 22, a first drive shaft 23, and a second drive shaft 24. The gearbox 22 can be connected to the output end of the motor 21. The first drive shaft 23 can be located on the side of the gearbox 22 facing the motor 21 and can be connected to the output end of the gearbox 22. The second drive shaft 24 is collinear with the first drive shaft 23 and can be located on the side of the gearbox 22 away from the motor 21. The second drive shaft 24 can be connected to the output end of the gearbox 22. The motor 21 can drive the first drive shaft 23 and the second drive shaft 24 to rotate through the gearbox 22, thereby driving the rear wing 100 to rise and fall relative to the vehicle body.

[0055] Corresponding to the arrangement of the components in drive module 2, refer to Figures 3 to 5As shown, the vibration damping and sound-absorbing cover 3 may include a first limiting groove 331, a second limiting groove 332, a gearbox limiting block 38, and a motor housing 34. The first limiting groove 331 accommodates a first drive shaft 23, which can pass through the vibration damping and sound-absorbing cover 3. The groove wall of the first limiting groove 331 can stop on both sides of the first drive shaft 23 to limit its movement. The second limiting groove 332 accommodates a second drive shaft 24, which can pass through the vibration damping and sound-absorbing cover 3. The groove wall of the second limiting groove 332 can stop on both sides of the second drive shaft 24 to limit its movement. Furthermore, the first limiting groove 331 and the second limiting groove 332... The configuration of 2 can also play a foolproof role in the assembly process of the vibration damping and sound absorbing cover 3 and the drive module 2. The gearbox limit block 38 can stop the gearbox 22 on the side away from the motor 21, that is, the gearbox 22 can be pressed against the gearbox limit block 38, which can further reduce the vibration of the gearbox 22. The gearbox limit block 38 can also be provided with a relief groove 381 for avoiding the screws of the gearbox 22. The motor cover 34 can be constructed as a semi-cylindrical structure to match the outer contour of the motor 21. The motor cover 34 can be placed on the outside of the motor 21 to reduce the noise radiation of the motor 21 body.

[0056] To facilitate fixing the vibration damping and sound-absorbing cover 3 to the lower surface of the mounting plate 1, refer to Figures 3 to 5 As shown, the vibration damping and sound-absorbing cover 3 can be provided with multiple outwardly extending mounting feet 35 on the side facing the mounting plate 1. Each mounting foot 35 can be provided with a first fastening mounting hole 351, through which the vibration damping and sound-absorbing cover 3 can be fastened to the mounting plate 1. To improve assembly efficiency, the mounting feet 35 can be positioned to correspond to the mounting bolt positions of the motor 21. This allows the vibration damping and sound-absorbing cover 3 to share mounting bolts with the motor 21, enabling the vibration damping and sound-absorbing cover 3 to be simultaneously fixed when the motor 21 is mounted onto the mounting plate 1.

[0057] To improve the structural strength of the vibration damping and sound-absorbing cover 3, reference is made to... Figure 9 and Figure 10 As shown, the lower surface of the vibration damping and sound absorbing cover 3 (i.e., the side surface facing away from the mounting plate 1) can be provided with a groove 36, and a cross-shaped reinforcing rib 39 can be provided in the groove 36. The depth of the groove 36 can be 2mm.

[0058] To improve the airflow guiding effect of the sound-absorbing panel 4, refer to Figures 11 to 13As shown, the lower surface of the flow-guiding sound-absorbing plate 4, which serves as the main flow-guiding surface, may include a first arc-shaped surface 43 and a second arc-shaped surface 44 connected to each other. The first arc-shaped surface 43 may be located in front of the second arc-shaped surface 44, and the radius of the first arc-shaped surface 43 may be smaller than that of the second arc-shaped surface 44. The front end of the first arc-shaped surface 43 is connected to the upper surface of the flow-guiding sound-absorbing plate 4, so that the front end of the lower surface of the flow-guiding sound-absorbing plate 4 has a semi-circular structure. The rear end of the first arc-shaped surface 43 may be connected to the front end of the second arc-shaped surface 44, and the first arc-shaped surface 43 may be tangent to the second arc-shaped surface 44 at the connection point, so that the lower surface of the flow-guiding sound-absorbing plate 4 is smooth and avoids affecting the flow-guiding effect. The rear end of the flow-guiding sound-absorbing plate 4 may be provided with a rear end surface 45, which may be perpendicular to the upper surface of the flow-guiding sound-absorbing plate 4. The rear end of the second arc-shaped surface 44 may be connected to the rear end surface 45.

[0059] In the specific embodiments of this disclosure, reference is made to Figure 12 As shown, the radius of the first arc surface 43 can be 14mm, the angle between the front end of the first arc surface 43 and the upper surface of the flow-guiding sound-absorbing plate 4 can be 75°, the distance between the rear end of the first arc surface 43 and the upper surface of the flow-guiding sound-absorbing plate 4 can be 10mm, the height of the rear end surface 45 can be 0.5mm, the angle between the rear end of the second arc surface 44 and the upper surface of the flow-guiding sound-absorbing plate 4 can be 5°, and the length of the flow-guiding sound-absorbing plate 4 in the front-back direction can be 148mm.

[0060] The lower surface of the flow-guiding and sound-absorbing plate 4 with the above structure can not only guide the airflow well, but also reduce the frictional resistance with the air and reduce the flow noise when cutting the air.

[0061] In addition, refer to Figure 13 As shown, the outer contour of the cross-section of the flow-guiding sound-absorbing plate 4 can match the outer contour of the cross-section of the sound-absorbing cavity 41, so that the sound-absorbing cavity 41 can cooperate with the second sound-absorbing micropore 42 to achieve a good sound absorption effect.

[0062] In a specific embodiment of this disclosure, a plurality of second sound-absorbing micropores 42 can be arranged at equal intervals. The diameter of the second sound-absorbing micropores 42 can be from 0.5 mm to 1.5 mm, preferably 1 mm, and the spacing between two adjacent second sound-absorbing micropores 42 can be from 7 mm to 9 mm, preferably 8 mm.

[0063] To facilitate the fixed connection between the airflow guiding sound-absorbing plate 4 and the tail fin plate 100, refer to Figure 11 As shown, the flow-guiding sound-absorbing plate 4 can be provided with multiple outwardly extending mounting lugs 46. The mounting lugs 46 can be provided on both sides of the flow-guiding sound-absorbing plate 4. The mounting lugs 46 can be provided with second fastening mounting holes 461. The flow-guiding sound-absorbing plate 4 can be fastened to the tail fin plate 100 through the second fastening mounting holes 461.

[0064] To improve the structural rigidity and stability of mounting plate 1, refer to Figure 14 As shown, multiple sets of reinforcing structures 10 can be provided on the lower surface of the mounting plate 1. These reinforcing structures 10 can be arranged along the length of the mounting plate 1, and reinforcing structures 10 can be provided on both sides of the mounting plate 1 corresponding to the drive module 2. Each set of reinforcing structures 10 can include two first reinforcing ribs 101 and a second reinforcing rib 102 connected between the two first reinforcing ribs 101. The two first reinforcing ribs 101 can extend parallel to each other and be spaced apart along the width of the mounting plate 1, and the second reinforcing rib 102 can be connected between the two first reinforcing ribs 101 to form an N-shaped structure. Through the reinforcing structures 10, the structural rigidity and stability of the mounting plate 1 can be significantly enhanced, and the vibration of the mounting plate 1 can be reduced. Furthermore, refer to... Figure 14 As shown, the number of studs on the mounting plate 1 corresponding to one side of the drive module 2 is greater than the number of studs on the mounting plate 1 corresponding to the other side of the drive module 2. Multiple sets of reinforcing structures 10 can be provided on the side of the mounting plate 1 with fewer studs, while only one set of reinforcing structure 10 can be provided on the side of the mounting plate 1 with more studs.

[0065] In a specific embodiment of this disclosure, the length of the first reinforcing rib 101 can be the same as the width of the mounting plate 1, the distance between two adjacent first reinforcing ribs 101 can be 44mm, the included angle between the second reinforcing rib 102 and the first reinforcing rib 101 can be 24°, and the width of both the first reinforcing rib 101 and the second reinforcing rib 102 can be 3mm.
