DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are intended only to describe specific embodiments and are not intended to limit this invention. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0028] The utility model provides a tail wing device and a vehicle including a tailgate assembly and the tail wing device provided by the utility model. The tail wing device belongs to the aerodynamic kit of the vehicle and can help increase the adhesion between the vehicle tires and the road surface to improve the driving performance of the vehicle.

[0029] See Figures 1 and 2 、 Figure 4 The tail wing device of the present invention is an exposed tail wing device, including a bracket assembly 10 and a tail wing assembly. The bracket assembly 10 includes a tail wing bracket 11. The tail wing bracket 11 includes a plug-in portion 112 and a tail wing mounting portion 111. The plug-in portion 112 is used to form an insertion portion 101. The insertion portion 101 is inserted into the tail door assembly from the outside of the tail door assembly, thereby being fixedly connected to the tail door assembly of the vehicle. The tail wing mounting portion 111 is located on the outside of the tail door assembly. The tail wing assembly is located on the outside of the tail door assembly and is mounted on the tail wing mounting portion 111 to withstand the force of airflow.

[0030] The tailgate assembly includes a tailgate structure 72, a tailgate mounting end 102 and a tailgate trim panel 71. The tailgate structure 72 serves as the main structure of the tailgate. The tailgate mounting end 102 is fixedly connected to the tailgate structure 72. The insertion portion 101 is fixedly connected to the tailgate mounting end 102. The tailgate trim panel 71 covers the tailgate structure 72 and the tailgate mounting end 102, and is provided with a bracket insertion hole 713 for the insertion portion 101 to pass through from the side of the tailgate trim panel 71 away from the tailgate structure 72. The side of the tailgate trim panel 71 away from the tailgate structure 72 is the outer side of the tailgate assembly.

[0031] Optionally, a gap is formed between the tailgate trim 71 and the tailgate structure 72 , and between the tailgate trim 71 and the tailgate mounting end 102 to prevent the tailgate trim 71 from contacting the tailgate structure 72 and / or the tailgate mounting end 102 and causing concave-convex deformation and abnormal noise.

[0032] Optionally, the tailgate mounting end 102 is connected to the side of the tailgate structure 72 facing the tailgate trim 71. When the insertion portion 101 and the tailgate mounting end 102 are connected, the insertion portion 101 is located in the gap between the tailgate trim 71 and the tailgate structure 72 and is not visible to the outside.

[0033] Optionally, see Figure 3 、 Figures 5 and 6 The tailgate trim panel 71 includes a tailgate outer trim panel 711 and a tailgate interior trim panel 712. The tailgate outer trim panel 711 is attached to a side of the tailgate interior trim panel 712 relatively away from the tailgate structure 72. A gap is formed between the tailgate interior trim panel 712 and the tailgate structure 72. Both the tailgate interior trim panel 712 and the tailgate outer trim panel 711 are provided with bracket sockets 713. The edges of the bracket sockets 713 provided on the tailgate interior trim panel 712 are provided with reinforced flanges.

[0034] In some embodiments, the tail assembly is an exposed active tail device, including a movable tail 41 movably mounted on the tail mounting portion 111, and the tail device also includes a drive assembly 30. Figure 1 、 Figure 3 、 Figures 5 and 6 The driving assembly 30 includes a tail driving member 31 and a connecting rod mechanism 32. The tail driving member 31 is installed on the bracket assembly 10 and drives the connecting rod mechanism 32. The connecting rod mechanism 32 is connected to the movable tail 41 and can drive the movable tail 41 to rotate relative to the tail bracket 11.

[0035] Figures 1 to 6 In the illustrated embodiment, the tail assembly further includes a fixed tail 42 fixedly mounted on the tail mounting portion 111. It is understood that in other embodiments, the tail assembly may include only the movable tail 41, or the tail assembly may include only the fixed tail 42 and eliminate the movable tail 41.

[0036] Further, see Figure 1 、 Figure 3 、 Figures 5 and 6The rear wing drive element 31 may be a push rod motor, the telescopic push rod of which is connected to the connecting rod mechanism 32. The bracket assembly 10 further includes a housing 12. The push rod motor is fixedly mounted within the housing 12, thereby forming a push rod assembly with the housing 12. The housing 12 and the plug-in portion 112 together form the insertion portion 101. The plug-in portion 112 is sleeved around the housing 12 and forms the side wall of the insertion portion 101. The end of the housing 12 that is relatively close to the tailgate structure 72 forms a docking end 122. The docking end 122 serves as the bottom end of the insertion portion 101 and is used for fixed connection with the tailgate mounting end 102. With this arrangement, when the rear wing assembly is subjected to differential downforce due to airflow, the rear wing assembly applies pressure to the tailgate mounting end 102 and the tailgate structure 72 through the bottom end of the plug-in portion 101, thereby applying downforce to the entire vehicle body.

[0037] Alternatively, as Figure 3 、 Figures 5 and 6 As shown, the docking end 122 extends from the end of the plug-in portion 112 relatively away from the wing mounting portion 111 and forms the bottom end of the insertion portion 101. In other embodiments, the docking end 122 may also be flush with the end of the plug-in portion 112 relatively away from the wing mounting portion 111, and the end of the plug-in portion 112 relatively away from the wing mounting portion 111 and the docking end 122 together form the bottom end of the insertion portion 101; the docking end 122 may also be lower than the end of the plug-in portion 112 relatively away from the wing mounting portion 111, and the end of the plug-in portion 112 relatively away from the wing mounting portion 111 forms the bottom end of the insertion portion 101.

[0038] It should be noted that in other embodiments, the housing 12 may be eliminated. After the housing 12 is eliminated, the tail drive assembly 31 is directly mounted on the tail bracket 11. When the tail assembly eliminates the movable tail 41 and retains only the fixed tail 42, the drive assembly 30 may be eliminated, and the tail assembly is now an exposed fixed tail 42. When the housing 12 or the drive assembly 30 is eliminated, the insertion portion 101 is entirely formed by the plug-in portion 112. The sidewalls of the plug-in portion 112 serve as the sidewalls of the insertion portion 101, and the end of the plug-in portion 112 that is relatively far from the tail mounting portion 111 serves as the bottom end of the insertion portion 101.

[0039] Furthermore, the tail wing bracket 11 further includes an insertion depth limiting portion 113 with an insertion opening 1131, and the insertion opening 1131 is connected to the plug-in portion 112 for sleeve-mounting the hollow cavity of the housing 12. Figures 2 and 3 、 Figures 5 and 6The insertion depth limiting portion 113 is provided at an end of the plug-in portion 112 relatively away from the tailgate structure 72. The cover shell 12 passes through the insertion opening 1131 to extend into the plug-in portion 112. A limiting flange 123 extending along the circumferential direction of the cover shell 12 is protruded from the outer periphery of the cover shell 12. The limiting flange 123 is stopped at an end of the insertion depth limiting portion 113 away from the plug-in portion 112 and the tailgate structure 72. The limiting flange 123 and the insertion depth limiting portion 113 are sealed by the first sealing member 51, and the first sealing member 51 surrounds the insertion opening 1131. With this arrangement, the housing 12 between the limiting flange 123 and the docking end 122 extends into the plug-in portion 112, while the remaining portion of the housing 12 is located outside the plug-in portion 112. The first sealing member 51 can prevent impurities such as dust and water droplets from entering the plug-in portion 112 through the insertion opening 1131, thereby preventing the housing 12 and the plug-in portion 112 from rusting.

[0040] Furthermore, the tail wing bracket 11 further includes a front support arm 114 and a rear support arm 115 located outside the rear door assembly, see Figure 1 、 Figures 3 and 4 The front support arm 114 and the rear support arm 115 are arranged in sequence along the X-axis direction of the vehicle coordinate system. One end of the front support arm 114 and one end of the rear support arm 115 are connected to the insertion depth limiter 113, and the other end of the front support arm 114 and the other end of the rear support arm 115 are connected to the rear wing mounting portion 111. Thus, the rear wing mounting portion 111, the front support arm 114, the insertion depth limiter 113 and the rear support arm 115 form a hollow space 116. A portion of the push rod assembly extends from the insertion depth limiter 113 and extends toward the rear wing mounting portion 111. This portion of the push rod assembly is exposed through the hollow space 116.

[0041] Optionally, at least a portion of the casing 12 and / or a portion of the tail driving component 31 and / or a portion of the connecting rod mechanism 32 are at least partially exposed outside the tail bracket 11 through the hollow space.

[0042] With this arrangement, the hollow space 116 makes the tail wing bracket 11 lighter, which helps to reduce the total weight of the tail wing device. In addition, the hollow space 116 exposes a portion of the push rod assembly, which improves the aesthetic appearance of the tail wing device and allows bystanders to observe the operation of the push rod assembly through the hollow space 116.

[0043] In other embodiments, the hollow space 116 may be eliminated, and the front support arm 114 and the rear support arm 115 may be combined into one support arm.

[0044] Further, see Figure 3A fixing lug 121 is fixedly provided at one end of the cover 12 which is relatively far away from the tailgate structure 72. The fixing lug 121 is fixedly connected to the tail wing mounting portion 111. This arrangement further improves the connection strength between the cover 12 and the tail wing bracket 11, thereby improving the integration of the push rod assembly and the tail wing bracket 11.

[0045] Further, see Figure 3 、 Figures 5 and 6 The size of the insertion depth limiting portion 113 is greater than the size of the bracket insertion hole 713. Therefore, when the depth of the plug-in portion 112 extending into the bracket insertion hole 713 reaches the maximum, the insertion depth limiting portion 113 is stopped on the outside of the rear door outer panel 711, and the side of the insertion depth limiting portion 113 facing away from the rear wing mounting portion 111 is overlapped with the outside of the rear door outer panel 711, and a second sealing member 52 is provided between the insertion depth limiting portion 113 and the rear door outer panel 711, and the two are sealed together by the second sealing member 52, and the second sealing member 52 surrounds the periphery of the bracket insertion hole 713.

[0046] This arrangement can prevent impurities such as dust and water droplets from entering the gap between the tailgate trim panel 71 and the tailgate structure 72 through the bracket insertion hole 713, thereby preventing the tailgate assembly from rusting.

[0047] Further, see Figure 3 The tail wing bracket 11 also includes a reinforcing rib 117, which connects the outer side wall of the plug-in portion 112 and the side of the insertion depth limiting portion 113 relatively away from the tail wing mounting portion 111. This arrangement can improve the structural strength of the tail wing bracket 11 and reduce the concentrated stress between the insertion depth limiting portion 113 and the plug-in portion 112.

[0048] During vehicle operation, the tail wing assembly is affected by airflow and generates downforce. This downforce is transmitted through the bracket assembly 10 to the tailgate assembly, and then to the vehicle body to improve adhesion between the wheels and the road. However, the tail wing assembly is also subject to external forces from other directions. For example, when crosswinds act on the tail wing assembly and bracket assembly 10, or when the vehicle rapidly starts, turns, or brakes, lateral or longitudinal forces are generated between the bracket assembly 10 and the tailgate assembly. The lateral force has a vector along the Y-axis of the vehicle coordinate system, and the longitudinal force has a vector along the X-axis of the vehicle coordinate system. These additional external forces place higher demands on the connection strength between the bracket assembly 10 and the tailgate assembly.

[0049] In view of this, the tail wing device of the present invention also includes a mounting assembly 20 fixedly connected to or integrally formed with the tailgate mounting end 102. The mounting assembly 20 is used to further improve the connection strength between the bracket assembly 10 and the tailgate assembly, so that the bracket assembly 10 and the tailgate assembly form a reliable rigid connection, thereby enabling the tail wing assembly and the bracket assembly 10 to resist more complex airflow external forces and prevent the bracket assembly 10 from moving abnormally relative to the tailgate assembly. Figures 4 to 6 The mounting assembly 20 includes at least side supports 211 and mounting feet 212 fixedly positioned relative to each other. The side walls of the insertion portion 101 are fixedly connected to the side supports 211, and the mounting feet 212 extend outwardly relative to the side walls of the insertion portion 101. The fixed connection or integral molding of the tailgate mounting end 102 with the mounting assembly 20 significantly improves the strength and reliability of the connection between the bracket assembly 10 and the mounting assembly 20 and the tailgate assembly.

[0050] Optionally, when the mounting assembly 20 and the tailgate mounting end 102 are integrally formed, both may be sheet metal components. When the mounting assembly 20 and the tailgate mounting end 102 are separately formed and fixedly connected, the mounting assembly 20 may be a sheet metal component or a non-sheet metal component, such as a casting or non-metallic component. Mounting assembly 20 formed of sheet metal components provides strong mechanical properties and durability.

[0051] In some embodiments, the mounting assembly 20 is formed separately from the tailgate mounting end 102 and fixedly connected. When the tailgate mounting end 102 and the tailgate structural member 72 are fixedly connected, the mounting assembly 20 is located in the gap between the tailgate trim panel 71 and the tailgate structural member 72 and is not visible to the outside.

[0052] Figures 5 and 6 In the tail wing device shown, the side support portion 211 and the outer peripheral wall of the plug-in portion 112 are fixedly connected, the mounting foot 212 extends outward relative to the outer peripheral wall of the plug-in portion 112, the docking end 122 of the shell 12 and the tailgate mounting end 102 are separately molded and fixedly docked, and the mounting foot 212 is also separately molded and fixedly docked with the tailgate mounting end 102. The pressure exerted by the tail wing device on the tailgate assembly is distributed over a larger area, and the tailgate mounting end 102 can withstand greater pressure.

[0053] The mounting assembly 20 provides lateral support for the bracket assembly 10 by pressing against the side wall of the insertion portion 101 through the side support portion 211. The provision of the mounting foot 212 increases the lateral size of the mounting assembly 20 on the insertion portion 101, and the ability of the tail wing device to resist the airflow resistance acting laterally along the insertion portion 101 is enhanced. The bracket assembly 10 and the tailgate structure 72 remain relatively fixed in the lateral and longitudinal directions perpendicular to the length direction of the insertion portion 101, thereby making the tail wing device better adapted to the complex and changeable airflow pressure.

[0054] In some embodiments, the tailgate mounting end 102 includes a bottom bracket 22 that is directly fixedly connected to the tailgate structure 72. The bottom bracket 22 and the mounting assembly 20 are formed separately. The bottom bracket 22 has multiple docking portions 221 arranged sequentially along a predetermined span direction. The bottom end of the insertion portion 101 and the mounting foot 212 are respectively fixedly connected to different docking portions 221. The predetermined span direction and the length direction of the insertion portion 101 form an angle. Figures 5 and 6 In the tail wing device shown, the preset span direction is set to the Y-axis direction of the vehicle coordinate system, the mounting foot 212 extends outward relative to the outer peripheral wall of the plug-in portion 112 along the preset span direction, and the length direction of the plug-in portion 101 is perpendicular to the preset span direction.

[0055] Furthermore, if Figures 5 and 6 As shown, the mounting assembly 20 includes two adapter brackets 21 of the same shape. The bottom bracket 22 and the adapter bracket 21 are both sheet metal parts and are formed separately. Each adapter bracket 21 includes a side support plate 2111 and a bent bottom plate 2121 that are integrally bent and connected. The side support plate 2111 forms the side support portion 211, and the bent bottom plate 2121 forms the mounting foot 212. The two side support plates 2111 are respectively spaced apart along the Y-axis direction of the vehicle coordinate system. The two bent bottom plates 2121 are respectively spaced apart along the Y-axis direction of the vehicle coordinate system, and the two bent bottom plates 2121 protrude from opposite sides of the plug-in portion 112 along the Y-axis direction of the vehicle coordinate system. The opposite sides of the plug-in portion 112 are arranged along the Y-axis of the vehicle coordinate system and are fixedly attached to the two side support plates 2111.

[0056] In some embodiments, when the tailgate mounting end 102 is fixedly connected to the tailgate structure 72 , the adapter bracket 21 is located in the space between the tailgate trim panel 71 and the tailgate structure 72 and is not visible to the outside.

[0057] Figures 5 and 6 In the illustrated rear wing device, the two opposing sides of the insertion portion 112, located along the Y-axis of the vehicle coordinate system, are fixedly connected to the two side support plates 2111 via first fasteners 61. The bottom bracket 22 includes first, second, and third docking portions 221, sequentially located along the Y-axis of the vehicle coordinate system. The two bent bottom plates 2121, serving as mounting feet 212, are fixedly connected to the first and third docking portions 221 on either side via second fasteners 62. The docking end 122, serving as the bottom end of the insertion portion 101, is fixedly connected to the second docking portion 221 located in the middle via third fasteners 63. The first, second, and third fasteners 61, 62, and 63 may be bolts, rivets, pins, or the like.

[0058] It can be understood that the number of docking parts 221 is not limited to three. The number of docking parts 221 can increase as the number of mounting feet 212 increases. The bottom end of the insertion part 101 is connected to one of the docking parts 221, and the mounting feet 212 are connected to the remaining docking parts 221. The forces exerted by the insertion part 101 and the mounting feet 212 on the bottom bracket 22 can be dispersed in different parts, that is, different docking parts 221 jointly bear the force of the tail wing device, which helps to improve the structural stability and load-bearing capacity of the bottom bracket 22.

[0059] With such an arrangement, a positioning space is formed between the two side support plates 2111 for the plug-in portion 112 to pass through. The lateral support of the plug-in portion 112 by the two side support plates 2111 improves the relative stability of the plug-in portion 112 and the tailgate structure 72 in the Y-axis direction of the vehicle coordinate system. Therefore, at least in the Y-axis direction of the vehicle coordinate system, a reliable rigid connection is formed between the bracket assembly 10 and the tailgate structure 72, so that the tail wing assembly and the bracket assembly 10 can resist the external force of the airflow from the lateral direction.

[0060] In other embodiments, the side support portion 211 can also form a positioning space for the insertion portion 101 to penetrate and extend along the length direction of the insertion portion 101 in other ways. For example, the two side support plates 2111 can also be arranged at intervals along the X-axis direction of the vehicle coordinate system, and a positioning space for the insertion portion 101 to extend into is formed between the two side support plates 2111. The two side support plates 2111 are respectively fixedly attached to the two side walls of the plug-in portion 112 that are arranged in opposite directions along the X-axis direction of the vehicle coordinate system. In this way, the bracket assembly 10 and the tailgate structure 72 can form a reliable rigid connection in the X-axis direction of the vehicle coordinate system, thereby improving the resistance of the rear wing assembly and the bracket assembly 10 to the external force of the longitudinal airflow.

[0061] In other embodiments, the preset span direction is not limited to the Y-axis direction of the vehicle coordinate system. For example, when the two adapter brackets 21 are staggered at different positions in the X-axis direction of the vehicle coordinate system, the bent base plate 2121 serving as the mounting base 212 is staggered at different positions in the X-axis direction of the vehicle coordinate system, and the bent base plate 2121 protrudes relative to the outer peripheral wall of the plug-in portion 112.

[0062] The number of adapter brackets 21 is not limited to two, and more adapter brackets 21 can be set. The side support plates 2111 of the multiple adapter brackets 21 can be arranged on the outer peripheral wall of the plug-in part 101, so that the multiple adapter brackets 21 together surround and form a positioning space for the plug-in part 101 to extend into, so that the plug-in part 101 located in the positioning space and the multiple side support plates 2111 are fixedly matched.

[0063] The larger the area of the side support plate 2111 in contact with the side wall of the insertion portion 101, the better the lateral support effect of the adapter bracket 21 on the insertion portion 101, and the stronger the ability of the tail wing assembly and the bracket assembly 10 to resist the lateral airflow force and the longitudinal airflow force. In some embodiments, the adapter bracket 21 may also include a positioning sleeve and a positioning flange that are coaxially fixedly connected. The positioning sleeve defines a positioning space for the insertion portion 101 to be sleeved. The positioning flange protrudes from the outer peripheral wall of the positioning sleeve. The positioning sleeve forms a side support portion 211 to laterally support the insertion portion 101. The positioning flange serves as a mounting foot 212. The bottom ends of the positioning flange and the insertion portion 101 are respectively connected to multiple different docking portions 221 on the tailgate mounting end 102.

[0064] In some other embodiments, the side support portion 211 and the mounting foot 212 may also be two separate structures that are formed and fixedly connected by fastening connectors.

[0065] Optionally, the bottom bracket 22 and the tailgate structure 72 are both sheet metal parts processed by stamping or forging. Specifically, the bottom bracket 22 can be an aluminum alloy part or a steel part.

[0066] In other embodiments, the bottom bracket 22 and the mounting assembly 20 serving as the tailgate mounting end 102 are formed separately and integrally formed with the tailgate structure 72 , and the bottom end of the insertion portion 101 and the mounting foot 212 are directly fixedly connected to the tailgate structure 72 .
