[0022] In related technologies, double-sided adhesive is typically used to attach the rear wing to the car's tailgate. To overcome the positioning difficulties associated with pure adhesive bonding, a specialized contour-following positioning fixture is usually required to assist in positioning. However, this installation method, which combines contour-following positioning fixtures with adhesive bonding, not only complicates the rear wing installation process but also increases additional tooling investment and operating costs.

[0023] In view of this, this application proposes a tail wing assembly. Figures 1 to 7 These are some embodiments of this application.

[0024] Please see Figures 1 to 3 In some embodiments of this application, the tail wing assembly includes a mounting body 1 and a tail wing 2; wherein, the mounting body 1 serves as the mounting carrier for the tail wing 2, and the mounting body 1 can be part of the tail door of a vehicle in the related art, or it can be assembled and installed on the tail door of a vehicle; no limitation is made here.

[0025] In some embodiments of this application, the tail wing assembly further includes multiple connecting structures 3, each of which includes a mating protrusion 31 and a mating hole 32 that cooperate with each other. The mating hole 32 extends laterally to be elongated, so that the mating protrusion 31 can move along the extending direction of the mating hole 32. One of the mating protrusion 31 and the mating hole 32 is disposed on the mounting body 1, and the other is disposed on the tail wing 2. In this case, the extending directions of the mating holes 32 of at least two of the connecting structures 3 intersect.

[0026] In this embodiment, the engagement of the insertion protrusion 31 and the mating hole 32 can restrict the separation of the tail wing 2 from the mounting body 1, so as to realize the assembly and installation of the tail wing 2 on the mounting body 1; and the form in which the insertion protrusion 31 can move along the extension direction of the mating hole 32 allows the tail wing 2 to be adjusted in position along the extension direction of the mating hole 32 when it is assembled on the mounting body 1 and not completely fixed, thereby improving the accuracy of the tail wing 2 installation and positioning.

[0027] The arrangement in which the extension directions of the mating holes 32 of at least two of the connecting structures 3 intersect allows the tail wing 2 to be adjusted in different directions, thereby further improving the accuracy of the tail wing 2 installation and positioning.

[0028] In conjunction with the above, in the technical solution of this application, the elongated mating hole 32 allows the insertion protrusion 31 to move along the extension direction of the mating hole 32 after mating with it. By making the extension directions of the elongated mating holes 32 in at least two connecting structures 3 intersect, the tail wing 2 can be adjusted in at least two directions when installed on the mounting body 1, thereby achieving precise positioning and installation of the tail wing 2. This installation method can effectively eliminate the need for the special contour positioning fixture required in related technologies, ensuring the installation accuracy of the tail wing 2 while simplifying the installation process of the tail wing 2 and reducing tool input and installation costs.

[0029] It should be further explained that although the insertion protrusion 31 can still move along the extension direction of the mating hole 32 after it mates with the mating hole 32, the mating between the insertion protrusion 31 and the mating hole 32 can restrict the tail wing assembly from separating from the mounting body 1, such as restricting the tail wing assembly from separating from the mounting body 1 in the assembly direction of the tail wing assembly. Based on this design, when the position of the tail wing 2 is adjusted, the mounting body 1 can provide a certain support function for the tail wing 2, thereby improving the stability of the tail wing 2 when the position is adjusted.

[0030] After the position of the tail wing 2 is adjusted, the tail wing assembly can be fixed to the mounting body 1 through the further engagement of the insertion protrusion 31 and the mating hole 32, or other components can be set to achieve the final fixation between the tail wing assembly and the mounting body 1.

[0031] Furthermore, the connection method of using multiple connection structures 3 to fix the tail wing assembly and the mounting body 1 in the above embodiment can effectively reduce costs compared with the method of using double-sided adhesive to stick around the entire circumference in related technologies.

[0032] Among them, double-sided tape full-circumference pasting refers to the method of using double-sided tape to stick and fix the entire edge of the rear wing 2 in contact with the vehicle body. In this application, multiple connecting structures 3 are used to connect the rear wing 2 and the mounting body 1, so that the rear wing 2 and the mounting body 1 can be firmly fixed with only a few mounting points.

[0033] Furthermore, in the case where the extending directions of the mating holes 32 in at least two of the connecting structures 3 intersect, the included angle between the extending directions of two mating holes 32 located in different connecting structures 3 is not limited; it can be 80°, 85°, 90°, 95°, 100°, etc.

[0034] In one specific embodiment of this application, the front-rear and left-right directions of the vehicle are used as directional references. One mating hole 32 of the two connecting structures 3 extends along the front-rear direction of the vehicle, and the other mating hole 32 extends along the left-right direction of the vehicle, so that the tail wing 2 can be adjusted in both the front-rear and left-right directions of the vehicle, thereby improving the accuracy of the tail wing 2 installation and positioning.

[0035] The assembly method of the mounting body 1, tail wing 2 and connecting structure 3 will now be described.

[0036] In one embodiment, the insertion protrusions 31 in the multiple connection structures 3 are all provided on the tail wing 2, and the mating holes 32 are all provided on the mounting body 1.

[0037] In another embodiment, the insertion protrusions 31 in the multiple connection structures 3 are all provided on the mounting body 1, and the mating holes 32 are all provided on the tail wing 2.

[0038] In another embodiment, a portion of the connecting structure 3 has a plug-in protrusion 31 disposed on the mounting body 1 and a mating hole 32 disposed on the tail wing 2; another portion of the connecting structure 3 has a plug-in protrusion 31 disposed on the tail wing 2 and a mating hole 32 disposed on the mounting body 1.

[0039] In the above embodiments, the type of the mating hole 32 is not limited. It can be a structural component fixedly mounted on the mounting body 1 or the tail wing 2, and the structural component is provided with a mounting hole; or a part of the mounting body 1 or the tail wing 2 can form the mating hole 32, that is, the mounting body 1 or the tail wing 2 is provided with a mounting hole.

[0040] Based on this, in some embodiments of this application, the mating hole 32 includes an assembly groove 321 disposed on the mounting body 1, and at least a portion of the insertion protrusion 31 extends into the assembly groove 321 and is movable along the extension direction of the assembly groove 321; in this embodiment, by directly providing the assembly groove 321 on the mounting body 1, the overall space occupied by the connecting structure 3 can be effectively reduced, and the number of parts of the tail wing assembly can be simplified to reduce manufacturing costs.

[0041] Meanwhile, the above methods allow the tail wing 2 to be positioned directly on the mounting body 1, maintaining the stability of the tail wing 2 during the adjustment process.

[0042] Furthermore, since the mounting slot 321 is located on the mounting body 1 and is covered by the tail wing 2 after assembly, the integrity of the tail wing 2 and the aesthetics of the integrated tail wing assembly can be ensured.

[0043] Please see Figure 5 In some embodiments of this application, the plug-in protrusion 31 includes a bolt connection pair 311, which passes through the assembly groove 321 and is fixedly connected to the mounting body 1. In this embodiment, when the bolt connection pair 311 passes through the assembly groove 321 and is not locked, the bolt connection pair 311 can restrict the separation between the tail wing 2 and the mounting body 1, and the bolt connection pair 311 can also move along the extension direction of the assembly groove 321 to realize the position adjustment of the tail wing 2.

[0044] After the tail wing 2 is positioned, the bolt connection 311 can be tightened to achieve a firm fixation between the mounting body 1 and the tail wing 2.

[0045] In some embodiments of this application, the insertion protrusion 31 includes a buckle 312, which passes through the assembly groove 321 and is engaged with the mounting body 1. In this embodiment, when the buckle 312 passes through the assembly groove 321 and is engaged at the periphery of the assembly groove 321, it can restrict the separation between the tail wing 2 and the mounting body 1. Since the buckle 312 only limits movement in one direction, it can also move along the extension direction of the assembly groove 321 to achieve position adjustment of the tail wing 2.

[0046] In some embodiments of this application, a portion of the insertion protrusions 31 in the multiple connection structures 3 include bolt connection pairs 311, and another portion of the insertion protrusions 31 includes buckles 312. When the tail wing 2 is assembled with the mounting body 1, the buckles 312 are first inserted into the corresponding mounting groove 321 and fastened to the periphery of the mounting groove 321. At this time, the mounting position of the tail wing 2 is adjusted. After the mounting position of the tail wing 2 is adjusted, the bolt connection pairs 311 are tightened to achieve a firm fixation between the tail wing 2 and the mounting body 1.

[0047] Since the tail wing 2 has been locked by the bolt connection pair 311, the part of the tail wing 2 with the buckle 312 cannot move along the extension direction of the mounting groove 321 corresponding to the buckle 312 due to the rigidity of the tail wing 2. The buckle 312 can also restrict the tail wing 2 from separating from the mounting groove 321 in the assembly direction, thereby ensuring the reliability of the assembly between the tail wing 2 and the mounting body 1.

[0048] The aforementioned assembly direction refers to the direction in which the rear wing 2 is installed onto the mounting body 1. If the rear wing 2 is installed onto the mounting body 1 in the vertical direction of the vehicle, the clip 312 and the bolt connection pair 311 can restrict the rear wing 2 from separating from the mounting body 1 in the vertical direction of the vehicle. At the same time, the locking of the bolt connection pair 311 restricts the other degrees of freedom of the rear wing 2 relative to the mounting body 1, such as restricting the rear wing 2 from moving relative to the mounting body 1 in the front-rear direction and left-right direction of the vehicle.

[0049] like Figures 2 to 3 As shown, in two adjacent mounting slots 321, one mounting slot 321 extends along the front-rear direction of the vehicle, and the other mounting slot 321 extends along the left-right direction of the vehicle, and both mounting slots 321 are used for the buckle 312 to be inserted and fixed.

[0050] Correspondingly, the extension direction of the mounting groove 321 corresponding to the bolt connection pair 311 is also the left-right direction or the front-back direction, so that after the position of the tail wing 2 is adjusted, the bolt connection pair 311 can still pass smoothly through the mounting groove 321 for locking and installation without interfering with the installation body 1.

[0051] In some embodiments of this application, at least one bolt connection pair 311 is disposed between two adjacent buckles 312 in the extending direction of the tail wing 2. This is because the buckles 312 can move along the mounting groove 321, and the buckles 312 and the mounting groove 321 can only be limited in one direction. However, the bolt connection pair 311 can achieve multi-directional limitation by locking. By providing a bolt connection pair 311 between two buckles 312, the part of the tail wing 2 corresponding to the buckle 312 is locked to ensure the reliable assembly between the tail wing 2 and the mounting body 1.

[0052] In some embodiments of this application, the tail wing 2 is provided with a mounting part 4 on the side facing the mounting body 1; the bolt connection pair 311 includes a nut 3111 and a bolt 3112, the nut 3111 is fixedly disposed on the mounting part 4, and the bolt 3112 passes through the mounting groove 321 from the side of the mounting body 1 away from the tail wing 2 and cooperates with the nut 3111; in this embodiment, by fixing the nut 3111 to the mounting part 4 on the tail wing 2, and by using the bolt 3112 to pass through the mounting groove 321 from the back of the mounting body 1 and lock it with the nut 3111, the connection point is not easily observed from the front of the tail wing 2 after assembly, thereby improving the overall aesthetics of the tail wing assembly.

[0053] In some embodiments of this application, the assembly gap between the nut 3111 and the mounting part 4 is 0.5mm; by leaving a certain assembly gap between the mounting part 4 and the nut 3111, the assembly interference between the nut 3111 and the mounting part 4 due to small dimensional deviations in the manufacturing or assembly process of the parts is avoided, and the tail wing 2 and the mounting body 1 are reliably fixed by the bolt connection pair 311.

[0054] Please see Figure 6 In some embodiments of this application, the tail wing assembly further includes at least one adhesive member 5, which is bonded between the tail wing 2 and the mounting body 1; by providing the adhesive member 5, the part of the tail wing 2 that is not fixed to the mounting body 1 by the connecting structure 3 is prevented from partially lifting, thereby enhancing the reliability of the fixation between the tail wing 2 and the mounting body 1.

[0055] In some embodiments of this application, the adhesive 5 is disposed between the tail wing 2 at both ends in its extension direction and the mounting body 1; in this embodiment, by providing the adhesive 5 between the end of the tail wing 2 and the mounting body 1, the tail wing 2 is prevented from warping or loosening, thus ensuring the stability and reliability of the tail wing 2 mounted on the mounting body 1.

[0056] Meanwhile, the adhesive 5, together with the bolt connection pair 311 and the buckle 312, fixes the installation form of the tail wing 2 and the mounting body 1. While ensuring the connection strength between the tail wing 2 and the mounting body 1, it also avoids the assembly complexity and high cost brought about by the double-sided adhesive full-circumference pasting method in related technologies.

[0057] In some embodiments of this application, the adhesive 5 includes double-sided adhesive.

[0058] In some embodiments of this application, in the extending direction of the mating hole 32, the assembly gap between the end of the mating hole 32 and the insertion protrusion 31 is L; wherein, L satisfies: 1.5mm≤L≤2mm; in this embodiment, if L is less than 1.5mm, there is a problem that the insertion protrusion 31 and the mating hole 32 are not easy to assemble and it is not conducive to the position adjustment of the tail fin 2; if L is greater than 2mm, there is a problem that excessive shaking or inaccurate positioning may occur after the insertion protrusion 31 and the mating hole 32 are assembled.

[0059] In the above embodiments, L satisfies the numerical range of 1.5mm ≤ L ≤ 2mm. The value of L can be 1.5mm, 1.52mm, 1.54mm, 1.56mm, 1.58mm, 1.6mm, 1.62mm, 1.64mm, 1.66mm, 1.68mm, 1.7mm, 1.72mm, 1.74mm, 1.76mm, 1.78mm, 1.8mm, 1.82mm, 1.84mm, 1.86mm, 1.88mm, 1.9mm, 1.92mm, 1.94mm, 1.96mm, 1.98mm, or 2mm. The value of L is not limited to the listed values; other unlisted values ​​within this range are also applicable.

[0060] It should be noted that the assembly clearance L is the distance that the insertion protrusion 31 can move in the extending direction of the mating hole 32.

[0061] In some embodiments of this application, the assembly gap between the insertion protrusion 31 and the mating hole 32 is 0.2 mm in the extension direction perpendicular to the mating hole 32. This assembly gap restricts the movement of the insertion protrusion 31 and the mating hole 32 relative to each other in the extension direction perpendicular to the mating hole 32, ensuring the stability of the fit between the insertion protrusion 31 and the mating hole 32, and avoiding wobbling or displacement of the tail wing 2 during adjustment or fixing due to excessive gap.

[0062] In some embodiments of this application, the straight-line distance between two adjacent connecting structures 3 is greater than 150mm; in this embodiment, this is configured to optimize the load distribution of the tail wing 1 on the mounting body 2, effectively improving the overall rigidity and stability of the tail wing assembly.

[0063] Among them, optimizing the load distribution involves adjusting the spacing between adjacent connecting structures 3 so that the aerodynamic load borne by the tail fin 2 can be more evenly distributed to each connecting structure 3, thereby reducing stress concentration in a single connecting structure 3 and improving the stability and durability of the tail fin assembly.

[0064] It should be noted that there is no limit to the maximum distance between two adjacent connecting structures 3. The distance can be designed according to the actual size of the tail fin to ensure that the air load borne by the tail fin 2 can be more evenly distributed to each connecting structure 3.

[0065] Furthermore, since tail fin 2 has a symmetrical structure, to ensure uniform stress distribution during tail fin 2 installation, please refer to [the relevant documentation / reference needed]. Figure 6 , In some embodiments of this application, multiple connecting structures 3 are respectively disposed on both sides of the centerline 6 of the tail fin 2 and are arranged symmetrically; such arrangement can prevent the tail fin 2 from being misaligned or twisted due to asymmetrical force, thereby improving installation stability.

[0066] This application also proposes a vehicle, which includes a rear wing assembly and a tailgate, wherein the tailgate includes the mounting body 1 or the mounting body 1 is mounted on the tailgate; the rear wing assembly is as described above. Since this vehicle adopts all the technical solutions of all the above embodiments, it has at least the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here.

[0067] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
