[0035] The specific implementation of the present invention will be further explained in detail below by describing the optimal embodiment with reference to the accompanying drawings.

[0036] A vehicle tail assembly comprises a mounting base 1, on which a tail structure is arranged; the tail structure comprises a middle wing 2 arranged on the mounting base 1 and two side wings 3 symmetrically distributed at both ends of the middle wing 2; the side wings 3 are connected to a driving structure for controlling the movement of the side wings 3, the driving structure comprises a swing mechanism connected to the side wings 3 and a driving mechanism for controlling the movement of the swing mechanism; the swing mechanism comprises a connecting component and a guide limit component; the connecting component comprises two swing rods 6 spaced apart and distributed on the side wings 3; the guide limit The positioning component includes two arc grooves 8 arranged at intervals on the mounting base 1, and the two arc grooves 8 are arranged on the mounting base 1 with different lengths; the two swing rods 6 on each of the side wings 3 are respectively inserted into an arc groove 8; the driving mechanism can push the connecting component to move in the arc groove 8 on the mounting base 1; the tail wing assembly 1-1 disclosed in the present invention, through the design of two arc grooves 8 with different lengths, allows the side wing 3 to be flipped first and then rotated, thereby increasing the windward area of ​​the tail wing, providing sufficient downforce for the entire vehicle, and enhancing the stability of the car when driving at high speed.

[0037] The vehicle tail wing assembly 1-1 disclosed in the present invention mainly comprises a mounting base 1, which is connected to a trunk lid 4, specifically to an inner plate of the trunk lid 4; in addition, a tail wing structure is arranged on the mounting base 1 in the present invention; the tail wing structure comprises a middle wing 2 arranged on the mounting base 1 and two side wings 3 symmetrically distributed at both ends of the middle wing 2; the side wings 3 are connected to a driving structure for controlling the movement of the side wings 3, the driving structure comprises a swing mechanism connected to the side wings 3 and a driving mechanism for controlling the movement of the swing mechanism; the swing mechanism comprises a connecting component and a guiding and limiting component; the connecting component comprises two swing rods 6 spaced apart on the side wings 3; the guiding and limiting component comprises two arc grooves 8 spaced apart on the mounting base 1, and the two arc grooves 8 are arranged on the mounting base 1 with different lengths; the two swing rods 6 on each of the side wings 3 are respectively inserted into an arc groove 8; The driving mechanism can push the connecting component to move in the arc groove 8 on the mounting base 1; in actual use, the driving mechanism can push the connecting component to move, so that the connecting component moves in the two arc grooves 8. In addition, in the present invention, the side wing 3 is inserted into the arc groove 8 of the mounting base 1 through the swing rod 6. The arc groove 8 not only plays a connecting role, but also plays a guiding role, ensuring the stability of the trajectory when the side wing 3 is flipped over; in addition, in the present invention, two arc grooves 8 are provided on the mounting base 1, and the two arc grooves 8 are distributed at intervals, and the length of one arc groove 8 is greater than the length of the other arc groove 8. Based on such a setting, in subsequent use, after the side wing 3 is flipped into place, because one swing rod 6 has been pressed against the end of the short arc groove 8, and the other swing rod 6 has not yet pressed against the end of the long arc groove 8, when the driving mechanism continues to push the connecting component, the connecting component will rotate, thereby realizing the rotation control of the side wing 3.

[0038] In the present invention, the long arc groove 8 is distributed on the side close to the rear window glass, and the short arc groove 8 is arranged close to the rear of the vehicle. This arrangement can realize the rotation of the side wing 3 toward the front of the vehicle, increase the contact area with the airflow, and thus ensure the downforce of the whole vehicle.

[0039] Furthermore, in the present invention, the arc groove 8 includes an inner slide groove and an upper through groove; the width of the inner slide groove is greater than that of the upper through groove, and the vertical section of the arc groove 8 is an inverted T-shape; based on such a setting, it is convenient to insert the swing rod 6 in the arc groove 8. In addition, the inner slide groove is an internal groove and a limiting guide groove, which is convenient for limiting the movement trajectory of the swing rod 6; and 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, which is beneficial to control the running trajectory of the wing 3.

[0040] In addition, it should be noted that the arc groove 8 of the present invention is not a pure circular arc groove, but a groove structure with an arc. It is theoretically feasible to design the short arc groove 8 of the present invention to be circular arc-shaped. However, because the long arc groove 8, in addition to realizing the flipping and swinging of the swing rod 6, also needs to rotate the side wing 3. In order to avoid interference, the end of the long arc groove 8 also needs to have an arc in the horizontal direction to avoid interference between the swing rod 6 and the inner wall of the arc groove 8 when the swing rod 6 rotates.

[0041] In addition, in order to prevent the swing rod 6 from escaping from the arc groove 8, on the basis that the arc groove 8 is an inverted T-shape, a limiting ball head is provided at the end of the swing rod 6 away from the side wing 3; 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 escaping from the corresponding arc groove 8.

[0042] Furthermore, the connecting component in the present invention also includes a transverse connecting rod, and the two ends of the transverse connecting rod are respectively connected to a swing rod 6; the setting of the transverse connecting rod plays a good connecting and limiting role, which can not only ensure the strength of the connecting component, but also ensure the synchronization of the movement of the connecting component. When it is subsequently connected with the linkage rod 7, the linkage rod 7 can be connected to the connecting component through the transverse connecting rod. At the same time, in order to avoid interference, the connection between the linkage rod 7 and the transverse connecting rod is also a movable connection structure. While realizing the pushing of the transverse connecting rod by the linkage rod 7, it can also avoid the operation interference of the linkage rod 7 when the transverse connecting rod rotates.

[0043] Furthermore, the driving mechanism in the present invention includes a driving component, which is a driving end, which is convenient for providing an external driving force for the flipping and rotation of the side wing 3. In addition, the driving component in the present invention 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, and generally the driving component drives the linkage rod 7 to move in the length direction of the mounting base 1, which is essentially to move along the Y direction of the whole vehicle; so that the linkage rod 7 can 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, so that after the flipping is in place, the linkage rod 7 continues to push the connecting component, and the swing rod 6 on one side of the connecting component cannot continue to move due to the limitation of the short arc groove 8, and the other swing rod 6 can continue to move, so 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 the present invention, the driving component includes a driving part, the driving part is connected to a driving screw 5, and a driving slider 51 is provided on the driving screw 5, and the driving slider 51 is connected to the linkage rod 7; the driving part of the present invention 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 axially along the driving screw 5, the present invention requires that the driving slider 51 is inserted into the waist-shaped groove 11 on the mounting base 1, and the driving slider 51 can move along the driving screw shaft, thereby driving the linkage rod 7 to move along the length direction of the mounting base 1.

[0045] In addition, in the present invention, a limiting mechanism is provided between the driving slider 51 and the mounting base 1; the limiting mechanism includes a waist-shaped groove 11 arranged on the mounting base 1; the driving slider 51 passes through the waist-shaped 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 drive of the linkage rod 7.

[0046] In addition, in the present invention, the linkage rod 7 is movably connected to the driving slider 51; the movable connection here mainly requires that the linkage rod 7 can have a certain swinging ability with the driving slider 51, because in the actual use of the present invention, the linkage rod 7 does not move in a linear direction, and because the trajectory of the swing rod 6 of the present invention is an arc, the linkage rod 7 has a swinging range in the up and down directions. In order to avoid the influence of the linkage rod 7 on the movement of the connecting parts, the present invention requires that the linkage rod 7 is movably connected to the driving slider 51; for example, the two can be connected by a rotating shaft or a pin shaft, or by a hinge, and the specific selection can be made according to actual needs.

[0047] Furthermore, the mounting base 1 in the present invention includes a base body 111, and the base body 111 is the main structure of the mounting base 1. In the present invention, a through-connection groove 11 is provided on the base body 111; the through-connection groove 11 includes a waist-shaped groove 11 arranged on the base body 111 and a through-connection groove 11 arranged on the base body 111; the waist-shaped groove 11 is designed along the length direction of the base body 111, so as to facilitate the trajectory limitation of the operation of the driving slider 51.

[0048] In addition, in the present invention, the linkage rod 7 passes through the connection groove 11 to connect with the connecting component; the connection groove 11 is larger than the outer diameter of the linkage rod 7; the setting of the connection groove 11 facilitates the linkage rod 7 to pass through the base body 111 to connect with the connecting component.

[0049] In addition, in the present invention, the two side wings 3 are driven by the same driving unit; the driving unit includes a dual-axis driving motor; one driving unit can realize synchronous control of the side wings 3 on both sides, ensure the synchronization of adjustment of the side wings 3 on both sides, and avoid the instability of the whole vehicle operation caused by the asynchronous adjustment of the side wings 3 on both sides.

[0050] In addition, in the present invention, a placement groove is provided on the base body 111; the driving part is arranged in the placement groove; the placement groove is an inner groove structure in the middle area of ​​the base body 111, which facilitates the storage arrangement of the driving part, and the subsequent middle wing 2 covers the top of the placement groove to achieve the sealing of the placement groove; in addition, the placement groove can also reduce the overall weight of the tail wing assembly 1-1.

[0051] A vehicle comprises a trunk cover 4, on which the vehicle tail wing assembly 1-1 is arranged.

[0052] specific:

[0053] The purpose of the present invention is to overcome the deficiencies of the prior art and to provide a flippable and rotatable automobile rear wing assembly 1-1, which can realize the flipping and rotation of the rear wing through a simple mechanism, has a relatively low cost and is light in weight.

[0054] Specifically, the driving part outputs power and is connected with the linkage mechanism. The linkage mechanism drives the connecting part to slide in the corresponding arc groove 8, thereby realizing the flipping of the side wing 3. When the swing rod 6 on one side moves into place in the corresponding arc groove 8, it cannot continue to slide and remains stationary. The linkage rod 7 continues to push the connecting part, which will cause the swing rod 6 on the other side that has not yet reached its position to rotate, thereby realizing the rotation operation of the side wing 3.

[0055] When the motor rotates in the reverse direction, the driving unit drives the linkage rod 7 to return to its original position, thereby driving the connecting component to slide in the reverse direction, thereby driving the tail wing to return to the closed state.

[0056] Obviously, the specific implementation of the present invention is not limited to the above-mentioned methods. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention, they are all within the protection scope of the present invention.
