DETAILED DESCRIPTION

[0066] Embodiments of the present application are described below in detail with reference to examples thereof illustrated in the accompanying drawings, in which like or similar elements or components throughout the drawings are designated by like reference numerals, and any description of the embodiments is intended for explaining the present application and should not be understood as a limitation thereto.

[0067] In the description of the present application, the terms "first", "second" are used only for the purpose of description and should not be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Thus, the features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "plurality" is at least two, for example, two, three, etc., unless otherwise explicitly specified.

[0068] The spoiler 1, the spoiler assembly 10 having the spoiler 1 and the vehicle 100 having the spoiler assembly 10 according to embodiments of the present application are described in detail below with reference to FIGS. 1-19.

[0069] Referring to FIGS. 1-2, 5, 8-11, 17, the tail wing 1 according to the embodiments of the present application includes a tail wing body and at least one triangular reinforcing rib 111 arranged on the tail wing body, each triangular reinforcing rib 111 including three rib bars for enclosing a triangle. Integrating the triangular reinforcing rib 111 on the tail wing body can achieve lightweight while improving the inherent frequency of the structure. The tail wing body is reinforced by the left and right symmetrically distributed rib bars.

[0070] In some embodiments, the rib bars of the triangular reinforcing rib 111 can be straight rib bars, as shown in FIGS. 5, 17; or can be rib bars with curved radii.

[0071] In some embodiments, the triangular reinforcing rib 111 is one.

[0072] In other embodiments, referring to FIGS. 5, 17, the triangular reinforcing rib 111 is multiple, and the multiple triangular reinforcing ribs 111 are connected to form a "rice" shaped triangular intersection structure. Because the triangle has a stable structure, compared with other shapes of reinforcing ribs such as quadrilateral, pentagon, hexagon, octagon, etc., the reinforcing effect is more stable when the tail wing 1 is designed to be reinforced by the "rice" shaped reinforcing rib, and the tail wing 1 has stronger rigidity. In addition, the "rice" shaped triangular reinforcing rib replaces the metal reinforcing plate in the related art, and after simulating and analyzing the wind pressure rigidity, palm pressure rigidity, finger pressure rigidity, strength, modal, dynamic rigidity, etc. of the tail wing assembly 10, it can be concluded that the "rice" shaped triangular reinforcing rib is more optimal and lighter than the metal reinforcing plate in the related art. The "rice" shaped mode of multiple triangular reinforcing ribs 111 connected is more conducive to structural design, and the rigidity and strength of the tail wing 1 in each direction can be more flexibly and conveniently adjusted by adjusting the distribution density, arrangement height, rib bar thickness, etc. of the triangular reinforcing rib 111.

[0073] Referring to FIGS. 1-2, 8-11, the tail wing assembly 10 according to the embodiments of the present application can include an adjusting mechanism 2 and the tail wing 1 of the above embodiments, the adjusting mechanism 2 being connected with the tail wing 1, and the adjusting mechanism 2 being used to adjust the pitch angle and / or vertical height of the tail wing 1. That is, the adjusting mechanism 2 can be used to adjust only the pitch angle of the tail wing 1, or only the vertical height of the tail wing 1, or the pitch angle and the vertical height of the tail wing 1. By changing the pitch angle and / or vertical height of the tail wing 1, the air resistance flowing through the tail wing 1 can be adjusted, and the airflow can provide an upward force or a downward force on the tail wing 1 to meet the use requirements.

[0074] The tail wing assembly 10 can be applied to the vehicle 100 or other equipment. For the convenience of description, the tail wing assembly 10 is applied to the vehicle 100 in the present application. When the tail wing assembly 10 is closed, the tail wing 1 can be integrated with the vehicle body to ensure the streamlining of the rear section of the vehicle body, so that the vehicle body has better aerodynamic performance. When the tail wing assembly 10 is opened, the tail wing 1 is separated from the vehicle body, and the tail wing 1 and the vehicle body have an intermediate hollow cavity, so that the air passes through better, which is beneficial to reduce the air resistance of driving. The same aerodynamic principle as the aircraft wing is used, but it is just the opposite application. The aircraft wing hopes to provide upward buoyancy through the air, while the tail wing assembly 10 of the vehicle 100 hopes to provide sinking force through the air to improve the driving stability of the vehicle 100. The lift of the tail is smaller than that of the head, which can effectively avoid excessive steering of the vehicle 100, reduce the grip of the rear wheels, and reduce the stability at high speed. The weight of the tail wing assembly 10 affects the power economy or battery endurance of the vehicle 100. After the triangular reinforcing ribs 111 are arranged on the tail wing 1, the tail wing 1 can be made of lighter materials without affecting the required strength and rigidity, so that the weight of the tail wing assembly 10 is lighter, which is beneficial to reduce the weight of the whole vehicle, thereby improving the power economy or battery endurance of the vehicle 100.

[0075] The tail wing assembly 10 is arranged on the back door of the vehicle 100. If the tail wing assembly 10 is too heavy, it will cause the back door support rod to be insufficient to support the weight of the back door, thereby causing the back door to be unable to be automatically opened, and the opened state cannot be guaranteed and the back door will fall down. The lightweight design of the tail wing assembly 10 can reduce the load of the back door, so that the weight of the back door can also be designed to be smaller.

[0076] According to the tail wing assembly 10 of the embodiment of the present application, the triangular reinforcing ribs 111 arranged on the tail wing body can increase the strength and rigidity of the tail wing 1, so that the tail wing 1 can be made of lighter materials without affecting the required strength and rigidity, which is beneficial to realize the lightweight of the tail wing assembly 10.

[0077] In some embodiments of the present application, referring to FIGS. 2, 5-7, 9-11, and 17, the tail wing body includes an inner plate 11 and an outer plate 12, the inner plate 11 is connected and fixed with the outer plate 12, the inner plate 11 is arranged on one side of the outer plate 12, and the triangular reinforcing ribs 111 are arranged on the inner plate 11. The inner plate 11 is a frame design structure reinforced by triangular (wreath-shaped) left-right symmetrical ribs. Compared with other shapes such as quadrilateral, pentagon, hexagon, and octagon, the frame design structure reinforced by triangular left-right symmetrical ribs is more stable and has greater rigidity.

[0078] In some embodiments, referring to FIG. 5 and FIG. 17, the triangular reinforcing ribs 111 are arranged on the side of the inner plate 11 facing the outer plate 12. Specifically, after the spoiler assembly 10 is installed on the vehicle body, the inner plate 11 is located below the outer plate 12, and the triangular reinforcing ribs 111 are arranged on the upper surface of the inner plate 11, so that the triangular reinforcing ribs 111 are not visible from the outside of the vehicle 100 and are hidden, and at the same time, the triangular reinforcing ribs 111 are arranged on the lower side of the inner plate 11, which can also reduce the falling of sundries into the triangular reinforcing ribs 111 and avoid the accumulation of sundries in the triangular reinforcing ribs 111, which is difficult to clean.

[0079] In other embodiments, the triangular reinforcing ribs 111 are arranged on the side of the inner plate 11 away from the outer plate 12. After the spoiler assembly 10 is installed on the vehicle body, the outer plate 12 is located above the inner plate 11, and the triangular reinforcing ribs 111 are arranged on the lower surface of the inner plate 11, so that the triangular reinforcing ribs 111 are not easily visible from the outside of the vehicle 100 and are hidden, and at the same time, the triangular reinforcing ribs 111 are arranged on the lower side of the inner plate 11, which can also reduce the falling of sundries into the triangular reinforcing ribs 111 and avoid the accumulation of sundries in the triangular reinforcing ribs 111, which is difficult to clean.

[0080] The outer plate 12 is designed based on CAE finite element size optimization of the thickness, and the optimal thickness is designed to meet the requirements under many conditions such as structural strength, structural stiffness, and modal, so as to realize lightweight. The weight is distributed to the inner plate 11 structure which has greater effect on stiffness and strength. Finally, the weight of the outer plate 12 is greatly reduced, and the triangular reinforcing ribs 111 of the inner plate 11 are slightly strengthened and increased in weight, so as to achieve the same mechanical properties and realize the overall comprehensive lightweight of the spoiler assembly 10.

[0081] In some embodiments of the present application, referring to FIG. 5 and FIG. 17, each triangular reinforcing rib 111 includes three rib strips for forming a triangle, and at least two rib strips are connected by a cylindrical rib 112.
