[0004] According to a first aspect of the present disclosure, a car rear spoiler is provided, including a lower spoiler plate for connection to an outer panel of a tailgate and an upper spoiler plate for connection to the lower spoiler plate, wherein the lower spoiler plate and the upper spoiler plate are connected at two ends and between the two ends, and at least a first air duct and a second air duct for airflow toward the rear windshield are formed between the lower spoiler plate and the upper spoiler plate.

[0005] Optionally, the lower tail fin extends obliquely rearward and is at least partially in the same plane as the rear windshield. The projection of the upper tail fin in the height direction partially overlaps with the projection of the lower tail fin. Airflow enters the first air duct and the second air duct along the lower tail fin and blows toward the rear windshield.

[0006] Optionally, the projection of the upper tail fin plate in the height direction overlaps with a large portion of the projection of the rear windshield, the rear windshield being configured as at least a portion of the first air duct and the second air duct.

Detailed Implementation

[0025] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0026] In this disclosure, unless otherwise stated, directional terms such as "upper," "lower," "left," and "right" generally refer to the vehicle's normal driving direction when the rear spoiler provided in this disclosure is normally installed. "Inner" and "outer" may refer to the inner and outer contours of the corresponding component or its location within or outside its surrounding environment, depending on the specific context. 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. The terms "first," "second," etc., used in this disclosure are for distinguishing one element from another and do not have sequential or importance implications.

[0027] To reduce wind resistance at the rear wing of a car, such as Figures 1 to 8As shown, this disclosure provides a car rear wing, which includes a lower rear wing plate 11 for connection to the outer panel 2 of the tailgate and an upper rear wing plate 12 for connection to the lower rear wing plate 11. The lower rear wing plate 11 and the upper rear wing plate 12 are connected at both ends and between the two ends, and at least a first air duct 101 and a second air duct 102 for blowing air toward the rear windshield 3 are formed between the lower rear wing plate 11 and the upper rear wing plate 12.

[0028] It should be noted that the lower tail fin plate 11 and the upper tail fin plate 12 can be connected at their ends or at the midpoint between them to form a first air duct 101 and a second air duct 102. Of course, this disclosure also includes embodiments in which the lower tail fin plate 11 and the upper tail fin plate 12 are connected at any position between their ends to form multiple air duct structures, more than two.

[0029] In the automotive rear wing disclosed herein, a hollowed-out design is added between the lower wing panel 11 and the upper wing panel 12 to form at least two air duct structures from front to rear. The first air duct 101 and the second air duct 102 can significantly reduce wind resistance in the rear wing area and guide airflow to the middle and rear windshield 3. Furthermore, this airflow can clean dust, foreign objects, etc., from the rear windshield 3. Compared with embodiments that use a rear wiper for cleaning, this saves on the arrangement of a rear wiper, reduces weight and cost, optimizes the aerodynamic performance of the entire vehicle, and meets the requirements of automobiles in terms of driving range and energy consumption.

[0030] like Figures 1 to 3 As shown, the lower rear wing panel 11 extends backward at an angle and is at least partially in the same plane as the rear windshield 3. In the height direction, the projection of the upper rear wing panel 12 partially overlaps with the projection of the lower rear wing panel 11. Airflow from the roof enters the first air duct 101 and the second air duct 102 and is blown towards the rear windshield 3 along the lower rear wing panel 11. The tilt angles of the lower rear wing panel 11 and the rear windshield 3 can be approximately the same, and they are approximately in the same plane. The aforementioned air duct structure is formed between the lower rear wing panel 11 and the upper rear wing panel 12. During vehicle operation, airflow from the roof enters the first air duct 101 and the second air duct 102 and is blown towards the rear windshield 3 along the lower rear wing panel 11. The first air duct 101 and the second air duct 102 are distributed on the left and right sides of the vehicle body structure, guiding the airflow from the roof into the hollowed-out rear wing cavity.

[0031] For example, the projection of the upper tail wing panel 12 in the height direction largely overlaps with the projection of the rear windshield 3, which is configured as at least a portion of the first air duct 101 and the second air duct 102. The rear windshield 3 may be configured as the bottom surface of the first air duct 101 and the second air duct 102, and the upper tail wing panel 12 may be configured as the top surface of the first air duct 101 and the second air duct 102, forming a hollow tail wing cavity, and guiding airflow through the tail wing cavity to the rear windshield 3.

[0032] Taking the connection between the lower tail fin plate 11 and the upper tail fin plate 12 at the midpoint between their two ends as an example, this disclosure provides a design for the connection structure at the midpoint between the two. For example... Figure 2 and Figure 5 As shown, the upper tail fin plate 12 has a body portion 1201 and a connecting portion 1202. The connecting portion 1202 and the lower tail fin plate 11 at least partially overlap in the height direction, that is, the connecting portion 1202 of the upper tail fin plate 12 extends to the lower tail fin plate 11, realizing an overlapping connection between the two. Of course, this disclosure also includes the lower tail fin plate 11 having a rearwardly extending first connecting portion and the upper tail fin plate 12 having a forwardly extending second connecting portion, with the first connecting portion and the second connecting portion overlapping and connecting, or the lower tail fin plate 11 having a connecting portion extending to the upper tail fin plate 12, realizing an overlapping connection between the two, all of which fall within the protection scope of this disclosure.

[0033] In this disclosure, such as Figure 2 , Figure 4 and Figure 5 As shown, the car's rear spoiler also includes a mounting box 13 connected between the main body 1201 and the lower spoiler plate 11. The mounting box 13 houses functional components 14. These functional components 14 can be at least one of a camera module, sensor, or probe; for example, a rear camera assembly housed within the mounting box 13 and snapped into the box body 131. The central location not only integrates the mounting of various functional components 14, allowing the mounting box 13 to be stably installed between the lower spoiler plate 11 and the upper spoiler plate 12, but also utilizes the mounting box 13, the tailgate inner panel 2, and the rear windshield 3 to form the necessary air duct structure. This achieves the wind resistance reduction and airflow guidance functions of the hollowed-out rear spoiler while satisfying requirements for aesthetics, manufacturing feasibility, modal design, rigidity, wind noise, and integrated intelligent driving functions. Furthermore, the functional components 14 can be completely integrated within the mounting box 13, providing excellent protection for them and ensuring the accuracy of the cameras and other functional components 14.

[0034] The rear windshield 3 is located between the housing 131 of the mounting box 13 and the outer panel 2 of the tailgate. An L-shaped seal 15 is provided between the housing 131 and the rear windshield 3. The L-shaped seal 15 can be sealing foam, which can seal the position of the mounting box 13 and also play a buffering role during high-frequency vibration.

[0035] The lower tail fin panel 11 can be a single piece of material. In exemplary embodiments of this disclosure, as... Figure 7 and Figure 8As shown, the lower tail wing panel 11 includes a first frame 111 and a top trim panel 112 fixed to the first frame 111. The first frame 111 and the tailgate outer panel 2 are connected by a plurality of first connectors 161 arranged at intervals along the front-rear direction. A first adhesive layer 113 may be provided between the top trim panel 112 and the first frame 111. The top trim panel 112 can be fixed to the first frame 111 by structural adhesive. The first connectors 161 can be bolts or clips, etc. In this embodiment, for example... Figure 7 and Figure 8 As shown, three first connecting pieces 161 are provided in the front-rear direction. The first connecting piece 161 at the front can be a buckle, and the two first connecting pieces 161 at the rear can be bolts, so as to stably and reliably install the lower tail wing plate 11 onto the outer tailgate plate 2. Figure 7 As shown, an inner tailgate panel 4 is provided on the inner side of the outer tailgate panel 2. The inner tailgate panel 4 forms a cavity with the outer tailgate panel 2 at the location where the aforementioned first connecting member 161 is provided, which can increase the structural strength at that location.

[0036] The upper tail fin plate 12 can be a single piece of plate. In exemplary embodiments of this disclosure, as... Figure 7 and Figure 8 As shown, the upper tail fin plate 12 includes a second frame 121 and a perforated decorative plate 122 fixed to the second frame 121. The perforated decorative plate 122 extends forward to the lower tail fin plate 11 at both ends and the middle position between the two ends. The middle extended portion forms the aforementioned connecting portion 1201. The first frame 111 and the second frame 121 can be connected by a second connector 162. The second connector 162 can be a bolt, which can achieve a firm connection between the upper tail fin plate 12 and the lower tail fin plate 11.

[0037] For example, the mounting box 13 includes a box body 131 and a box cover 132. The box cover 132 is fixed to the second frame 121 and snapped into the hollowed-out decorative panel 122. The front end of the box body 131 is connected to the first frame 111 through a third connector 163, and the rear end is snapped into the box cover 132.

[0038] There are several ways to fix the perforated decorative panel 122 to the second frame 121. For example, a second adhesive layer 123 is provided between the perforated decorative panel 122 and the second frame 121, and it is fixed to the second frame 121 by structural adhesive. Alternatively, a combination of adhesive and fasteners can be used. Considering that the rear end of the perforated decorative panel 122 also needs to be connected to the box cover 132, such as... Figure 7 and Figure 8 As shown, the rear end of the hollowed-out decorative panel 122 is fastened to the second frame 121 by bolts 164.

[0039] The lid 132 is glued and fixed to the second frame 121. The front end of the lid 132 is snapped into the hollowed-out decorative panel 122. The front end of the box body 131 is connected to the first frame 111 through the second connector 162, and the rear end is snapped into the lid 132. This not only achieves a stable connection between the box body 131 and the lid 132, but also achieves a connection between the entire mounting box 13 and the lower tail wing plate 11 and the upper tail wing plate 12, thus stably fixing the mounting box 13 in the middle position.

[0040] In the embodiments described above, the first frame 111 of the lower rear wing panel 11 and the second frame 121 of the upper rear wing panel 12 can be any suitable structure. Considering the load-bearing function of the first frame 111 and the second frame 121, at the position between the two ends, the dimensions of the first frame 111 in the longitudinal direction are configured to cover the roof trim panel 112, the perforated trim panel 122, and at least a portion of the cover 132. The dimensions of the second frame 121 in the longitudinal direction are configured to cover the perforated trim panel 122 and at least a portion of the cover 132. By designing the dimensions of the first frame 111 and the second frame 121 in the longitudinal direction, a reliable connection of the vehicle body internal structure can be achieved, thereby optimizing the connection structure between the static and dynamic parts.

[0041] According to a second aspect of this disclosure, a car is provided that includes the rear wing described above. This car has all the beneficial effects of the aforementioned rear wing, which will not be repeated here.
