[0001] This invention relates to the field of automotive rear wings, specifically to an automotive rear wing assembly and a vehicle having the automotive rear wing assembly. Background Technology

[0002] With the gradual development of automotive intelligence, electric rear wings are being used more and more widely. When a car is traveling at high speed, according to the principles of aerodynamics, in order to effectively reduce and overcome the influence of air resistance, the rear wing can generate a large adhesion force to the ground. It can offset some of the lift, effectively control the car's grip, reduce the drag coefficient accordingly, and allow the car to stick to the road surface, thereby improving driving stability. At the same time, it also makes the car's lines more beautiful and enhances its technological feel.

[0003] Most of the rear wings currently on the market are either one-piece or three-section. The main body of the rear wing cannot swing or rotate, resulting in limited downforce and failing to meet the high-speed driving needs of users.

[0004] According to the extendable tail wing mechanism in document CN116853367A, it can only extend laterally and cannot swing or rotate the left and right wings. Due to the limitation of the lifting mechanism, the frontal area of ​​the tail wing body is small, resulting in limited downforce provided to the car.

[0035] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and the description of the preferred embodiments.

[0036] A vehicle rear wing assembly includes a mounting base 1 on which a rear wing structure is mounted. The rear wing structure includes a central wing 2 mounted on the mounting base 1 and two side wings 3 symmetrically distributed at both ends of the central wing 2. The side wings 3 are connected to a drive structure for controlling their movement. The drive structure includes a swing mechanism connected to the side wings 3 and a drive mechanism for controlling the movement of the swing mechanism. The swing mechanism includes a connecting component and a guide limiting component. The connecting component includes two swing rods 6 spaced apart on the side wings 3. The guide limiting component... The component includes two arc-shaped grooves 8 spaced apart on the mounting base 1, the two arc-shaped grooves 8 having different lengths on the mounting base 1; two swing rods 6 on each of the side wings 3 are respectively inserted into one arc-shaped groove 8; the drive mechanism can push the connecting component to move within the arc-shaped grooves 8 on the mounting base 1; the rear wing assembly 1-1 disclosed in this invention, through the design of two arc-shaped grooves 8 of different lengths, allows the side wings 3 to first flip and then rotate, thereby increasing the frontal area of ​​the rear wing, providing sufficient downforce for the whole vehicle, and enhancing the stability of the car at high speeds.

[0037] The automotive rear wing assembly 1-1 disclosed in this invention mainly includes a mounting base 1, which is connected to a trunk lid 4, specifically to the inner panel of the trunk lid 4. Furthermore, the mounting base 1 in this invention is provided with a rear wing structure. The rear wing structure includes a central wing 2 disposed on the mounting base 1 and two side wings 3 symmetrically distributed at both ends of the central wing 2. The side wings 3 are connected to a drive structure for controlling the movement of the side wings 3. The drive structure includes a swing mechanism connected to the side wings 3 and a drive mechanism for controlling the movement of the swing mechanism. The swing mechanism includes a connecting component and a guide limiting component. The connecting component includes two swing rods 6 spaced apart on the side wings 3. The guide limiting component includes two arc-shaped grooves 8 spaced apart on the mounting base 1, the two arc-shaped grooves 8 having different lengths on the mounting base 1. The two swing rods 6 on each side wing 3 are respectively inserted into one arc-shaped groove 8. The drive mechanism can push the connecting component to move within the arc-shaped groove 8 on the mounting base 1. In actual use, the drive mechanism can push the connecting component to move within the two arc-shaped grooves 8. In addition, in this invention, the side wing 3 is inserted into the arc-shaped groove 8 of the mounting base 1 via a swing rod 6. The arc-shaped groove 8 serves as both a connector and a guide, ensuring the stability of the trajectory of the side wing 3 when it flips. Furthermore, in this invention, the mounting base 1 has two arc-shaped grooves 8, which are spaced apart. The length of one arc-shaped groove 8 is greater than the length of the other. Based on this arrangement, in subsequent use, after the side wing 3 has flipped into place, because one swing rod 6 has already pressed against the end of the shorter arc-shaped groove 8 while the other swing rod 6 has not yet pressed against the end of the longer arc-shaped groove 8, the connecting component will rotate when the drive mechanism continues to push it, thereby achieving rotation control of the side wing 3.

[0038] In this invention, the long arc-shaped grooves 8 are distributed on the side near the rear window glass, and the short arc-shaped grooves 8 are arranged near the rear of the vehicle. This arrangement allows the side wings 3 to rotate towards the front of the vehicle, increasing the contact area with the airflow, thereby ensuring the downforce of the entire vehicle.

[0039] Furthermore, in this invention, the arc-shaped groove 8 includes an inner sliding groove and an upper through groove; the width of the inner sliding groove is greater than the width of the upper through groove, and the vertical cross-section of the arc-shaped groove 8 is inverted T-shaped; based on this setting, it is convenient to insert the swing rod 6 into the arc-shaped groove 8. In addition, the inner sliding groove is an internal groove and a limiting guide groove, which is convenient to limit the movement trajectory of the swing rod 6; while the upper through groove is a connecting groove and also a limiting groove. The width of the upper through groove is generally adapted to the outer diameter of the swing rod 6, which can ensure that the swing rod 6 has a limited trajectory when swinging, thereby facilitating the control of the running trajectory of the side wing 3.

[0040] Additionally, it should be noted that the arc groove 8 of this invention is not a pure circular arc groove, but a groove structure with an arc. This is because the short arc groove 8 of this invention is theoretically feasible in a circular arc shape. However, because the long arc groove 8, in addition to realizing the flipping and swinging of the swing rod 6, also requires the side wing 3 to rotate, in order to avoid interference, the end of the long arc groove 8 also needs to have an arc in the horizontal direction to prevent the swing rod 6 from interfering with the inner wall of the arc groove 8 when it rotates.

[0041] In addition, to prevent the swing rod 6 from disengaging from the arc groove 8, a limiting ball head is provided at the end of the swing rod 6 away from the side wing 3, based on the inverted T-shape of the arc groove 8; the diameter of the limiting ball head is larger than the width of the upper through groove; the limiting ball head acts as a limiting block to prevent the swing rod 6 from disengaging from the corresponding arc groove 8.

[0042] Furthermore, the connecting component in this invention also includes a transverse connecting rod, with each end of the transverse connecting rod connected to a swing rod 6. The transverse connecting rod serves as a good connection and limiter, ensuring not only the strength of the connecting component but also the synchronicity of its movement. When connected to the linkage rod 7 later, the linkage rod 7 can be connected to the connecting component through the transverse connecting rod. At the same time, to avoid interference, the connection between the linkage rod 7 and the transverse connecting rod is also a movable connection structure. This allows the linkage rod 7 to push the transverse connecting rod while preventing operational interference between the transverse connecting rod and the linkage rod 7 when the latter rotates.

[0043] Furthermore, the driving mechanism in this invention includes a driving component, which is a driving end, to provide external driving force for the flipping and rotation of the side wing 3. In addition, the driving component is connected to the connecting component through a linkage component. The linkage component includes a linkage rod 7 connected to the connecting component, and the driving component is movably connected to the linkage component. The driving component can drive the linkage rod 7 to be arranged along the length direction of the mounting base 1. In subsequent use, the driving component drives the linkage rod 7 to move. Generally, the driving component drives the linkage rod 7 to move along the length direction of the mounting base 1, which is essentially moving along the Y direction of the whole vehicle. This allows the linkage rod 7 to push the connecting component to move, so that the connecting component moves around the arc groove 8, thereby realizing the flipping operation of the side wing 3. After the flipping is in place, the linkage rod 7 continues to push the connecting component. The swing rod 6 on one side of the connecting component cannot continue to move due to the restriction of the short arc groove 8, while the other swing rod 6 can continue to move. Therefore, the side wing 3 will rotate around the swing rod 6 in the short arc groove 8, thereby realizing the rotation operation of the side wing 3.

[0044] In this invention, the driving component includes a driving part, which is connected to a driving screw 5. The driving screw 5 is provided with a driving slider 51, which is connected to a linkage rod 7. In this invention, the driving part drives the linkage screw to rotate, and the driving screw 5 drives the driving slider 51 to move. In order to ensure that the driving slider 51 can move along the axial direction of the driving screw 5, this invention requires the driving slider 51 to be inserted into the waist-shaped groove 11 on the mounting base 1. The driving slider 51 can move along the axis of the driving screw, thus driving the linkage rod 7 to move along the length direction of the mounting base 1.

[0045] In addition, in this invention, a limiting mechanism is provided between the driving slider 51 and the mounting base 1; the limiting mechanism includes an oblong groove 11 provided on the mounting base 1; the driving slider 51 passes through the oblong groove 11 and is connected to the linkage rod 7; the setting of the limiting mechanism plays a good restraining role, which can prevent the driving slider 51 from rotating, thereby changing the rotation of the driving slider 51 into lateral movement, which facilitates the lateral driving of the linkage rod 7.

[0046] Furthermore, in this invention, the linkage rod 7 is movably connected to the drive slider 51. This movable connection primarily requires that the linkage rod 7 and the drive slider 51 have a certain swinging capability. This is because, in actual use, the linkage rod 7 does not move linearly; since the trajectory of the swing rod 6 is an arc, the linkage rod 7 has a swinging range in the up-down direction. To avoid the linkage rod 7 affecting the movement of the connecting components, this invention requires that the linkage rod 7 and the drive slider 51 be movably connected. For example, they can be connected by a pivot or pin, or by a hinge; the specific connection can be selected according to actual needs.

[0047] Furthermore, the mounting base 1 in this invention includes a base body 111, which is the main structure of the mounting base 1. The base body 111 is provided with a through groove 11. The through groove 11 includes an oblong groove 11 and a through groove 11 provided on the base body 111. The oblong groove 11 is designed along the length of the base body 111 to facilitate the trajectory limitation of the drive slider 51.

[0048] In addition, in this invention, the linkage rod 7 passes through the through groove 11 and is connected to the connecting component; the through groove 11 is larger than the outer diameter of the linkage rod 7; the through groove 11 facilitates the linkage rod 7 to pass through the base body 111 and be connected to the connecting component.

[0049] In addition, in this invention, the two side wings 3 are driven by the same drive unit; the drive unit includes a dual-shaft drive motor; it can realize the synchronous control of the two side wings 3 with one drive unit, ensuring the synchronicity of the adjustment of the two side wings 3, and avoiding the instability of the whole vehicle operation caused by the asynchronous adjustment of the two side wings 3.

[0050] In addition, the base body 111 described in this invention is provided with a mounting groove; the drive unit is arranged in the mounting groove; the mounting groove is an inner groove structure in the middle area of ​​the base body 111, which facilitates the storage and arrangement of the drive unit. Subsequently, the intermediate wing 2 covers the mounting groove to seal it; in addition, the mounting groove can also reduce the overall weight of the tail wing assembly 1-1.

[0051] A vehicle includes a trunk lid 4, on which the vehicle rear spoiler assembly 1-1 is provided.

[0052] specific:

[0053] The purpose of this invention is to overcome the shortcomings of the prior art and provide a foldable and rotatable car rear wing assembly 1-1. This structure can achieve the folding and rotation of the rear wing through a simple mechanism, with relatively low cost and light weight.

[0054] Specifically, the drive unit outputs power and connects with the linkage mechanism. The linkage mechanism drives the connecting component to slide in the corresponding arc groove 8, thereby realizing the flipping of the side wing 3. When one side swing rod 6 moves into place in the corresponding arc groove 8, it can no longer slide and remains stationary. The linkage rod 7 continues to push the connecting component, which will cause the swing rod 6 on the other side that has not yet reached the position to rotate, thereby realizing the rotation operation of the side wing 3.

[0055] When the motor reverses, the drive unit drives the linkage rod 7 back to its original position, thereby causing the connecting parts to slide in the opposite direction, thus causing the tail fin to return to the closed state.

[0056] Obviously, the specific implementation of this invention is not limited to the above-described methods. Any non-substantial improvements made using the inventive concept and technical solution of this invention are within the protection scope of this invention.
