Abstract
Description
Technical Field
[0001] This utility model relates to the field of vehicle technology, and in particular to a spoiler mounting structure and a vehicle. Background Technology
[0002] In automotive aerodynamic design, spoilers, as key components for reducing wind resistance, are typically fixed between the inner and outer panels of the tailgate using welded bracket structures. Traditional installation methods involve welding zigzag-shaped metal brackets to corresponding positions on the inner and outer panels, using the coaxial holes of the two bracket sets to create bolt mounting channels, and finally securing the spoiler with through bolts and nuts. However, this method is prone to bolt insertion difficulties. The inner and outer panel brackets require multiple independent welding processes, and the combined effects of welding heat deformation and tooling positioning errors can easily lead to coaxiality deviations in the mounting holes, making bolt insertion difficult. Utility Model Content
[0003] The main purpose of this utility model is to propose a spoiler mounting structure and vehicle, which can be used for spoiler mounting to the rear door, or for spoiler mounting to other parts of the vehicle body.
[0004] To achieve the above objectives, the spoiler mounting structure proposed in this utility model includes:
[0005] The rear door has mounting holes;
[0006] A spoiler, integrating a fixing member that passes through the mounting hole; and
[0007] A support bushing is provided on the side of the rear door away from the outer surface. The fastener also passes through the support bushing. The fastener includes a positioning section. The outer wall of the positioning section forms a rotation limit fit with the inner wall of the mounting hole. The end of the fastener is fixed to the spoiler by cooperating with the support bushing through a fastening structure.
[0008] In one embodiment, the fastening structure includes a threaded section and a corresponding locking nut at the end of the fastener, or a pin hole and a corresponding pin at the end of the fastener, or a snap fastener and a corresponding latch at the end of the fastener.
[0009] In one embodiment, the support bushing is detachably abutted against the inner surface of the rear door.
[0010] In one embodiment, the tailgate includes an outer tailgate panel and an inner tailgate panel connected to the outer tailgate panel, the mounting hole is provided in the outer tailgate panel, and the support bushing is provided between the outer tailgate panel and the inner tailgate panel.
[0011] In one embodiment, the inner panel of the back door is provided with clearance holes for the support bushing to be installed on the fixing member.
[0012] In one embodiment, the cross-section of the positioning segment is a prism structure, and the mounting hole is adapted to the prism structure.
[0013] In one embodiment, the fastener further includes a fastening section located at the end of the positioning section away from the spoiler, and the support bushing is provided with a clearance through hole for the fastening section to pass through. The fastening structure includes the fastening section and a corresponding locking nut, and the locking nut is screwed to the fastening section and cooperates with the support bushing to form an axial preload limit.
[0014] In one embodiment, the outer diameter of the fastening section is smaller than the outer diameter of the positioning section.
[0015] In one embodiment, the contour of the end of the support bushing away from the fastening structure is adapted to the inner contour of the rear door to form a surface-to-surface contact fitting assembly.
[0016] In one embodiment, the support bushing is provided with a relief groove that matches the shape of the positioning section, and the inner wall of the relief groove forms a rotational limiting fit with the outer wall of the positioning section.
[0017] In one embodiment, the fixing member and the spoiler are integrally formed by injection molding.

[0034] In automotive aerodynamic design, spoilers, as key components for reducing wind resistance, are typically fixed between the inner and outer panels of the tailgate using welded bracket structures. Traditional installation methods involve welding zigzag-shaped metal brackets to corresponding positions on the inner and outer panels, using the coaxial holes of the two bracket sets to create bolt mounting channels, and finally securing the spoiler with through bolts and nuts. However, this method is prone to bolt insertion difficulties. The inner and outer panel brackets require multiple independent welding processes, and the combined effects of welding heat deformation and tooling positioning errors can easily lead to coaxiality deviations in the mounting holes, making bolt insertion difficult.
[0035] In addition, the bolt channels formed by the welding brackets of the inner and outer panels are rigid constraints, making it difficult to compensate for the matching tolerance between the tailgate and the spoiler during the final assembly stage. This often requires manual hole enlargement or grinding adjustments, which affects assembly efficiency.
[0036] Therefore, this utility model proposes a spoiler mounting structure that can be used for mounting a spoiler to the rear door, or for mounting a spoiler to other parts of the vehicle body.
[0037] Please see Figures 1 to 3 In one embodiment of this utility model, the spoiler mounting structure includes a rear tailgate 10, a spoiler 20, and a support bushing 40. The rear tailgate 10 is provided with a mounting hole 111. The spoiler 20 integrates a fixing member 30, which passes through the mounting hole 111. The support bushing 40 is provided on the inner surface side of the rear tailgate 10. The fixing member 30 passes through the support bushing 40, and the end of the fixing member 30 is fastened to the support bushing 40 through a fastening structure 50 to fix the spoiler 20.
[0038] During installation, the spoiler 20 is installed on the rear door 10, the fastener 30 passes through the mounting hole 111 and the support bushing 40, and then the fastener 30 is engaged by the fastening structure 50 at its end.
[0039] In one embodiment, the fastening structure 50 includes a threaded section 51 and a corresponding locking nut 52 disposed at the end of the fixing member 30. The locking nut 52 is installed on the threaded section 51, and the locking nut 52 and the support bushing 40 form an axial pre-tightening limit, thereby fixing the spoiler 20.
[0040] In one embodiment, the fastening structure 50 includes a pin hole and a corresponding pin at the end of the fastener 30, the pin forming an axial pre-tightening limit with the support bushing 40, thereby fixing the spoiler 20.
[0041] In one embodiment, the fastening structure 50 includes a snap-fit and a corresponding locking buckle at the end of the fastener 30. Additionally, it prevents the nut or pin from loosening under vibration, further enhancing connection stability. The support bushing 40 has an anti-loosening boss or groove on the side facing the fastener 30. The top surface of the anti-loosening boss or groove presses against the mounting plane of the locking nut 52 or pin, forming an axial pre-tightening limit. Through the boss design surrounding the fastener, pre-tightening force is generated by the compression deformation during assembly, preventing the nut or pin from loosening under vibration.
[0042] It should be noted that the integrated downward-extending fixing member 30 of the spoiler 20 refers to the integration of the fixing bracket, which originally required separate welding, with the spoiler 20 body. That is, a rigid connecting column is directly formed on the lower surface of the rear spoiler 20 (i.e., the side near the mounting surface of the rear tailgate 10). The connecting column extends in the vertical direction. In one embodiment, the fixing member 30 and the spoiler 20 adopt a common mold injection molding process ("two-color injection molding process" or "insert injection molding process"). Metal inserts or reinforcing fiber structures are pre-embedded in the spoiler 20 substrate (usually made of plastic material), so that the fixing member 30 and the spoiler 20 form a seamless integral structure, eliminating the assembly tolerance of traditional split brackets.
[0043] The technical solution of this utility model integrates a downwardly extending fixing member 30 into the spoiler 20. The fixing member 30 is integrally set with the spoiler 20, avoiding the positioning deviation caused by welding heat deformation. During installation, the fixing member 30 only needs to be inserted into the mounting hole 111 of the rear door 10, saving the time-consuming operation of adjusting the coaxiality of the inner and outer panel brackets in the traditional process. In addition, the integrated design can reduce the number of parts and facilitate lightweight design.
[0044] Specifically, in order to reduce the positioning deviation caused by welding heat deformation, the support bushing 40 can be separated from the inner surface of the rear door 10, that is, the support bushing 40 is independently set; furthermore, the support bushing 40 is made of plastic injection molding, which is convenient for lightweight design.
[0045] Specifically, the fixing member 30 and the spoiler 20 are integrally formed by injection molding; and in order to improve the contact stability between the spoiler 20 and the tailgate 10, an abutment section is provided on the side of the spoiler 20 facing the tailgate 10. The abutment section forms multi-point contact with the surface of the tailgate 10, and the abutment section is adapted to the contour design of the tailgate 10.
[0046] Specifically, the tailgate 10 includes an outer tailgate panel 11 and an inner tailgate panel 12 connected to the outer tailgate panel 11. The mounting hole 111 is provided in the outer tailgate panel 11, and the support bushing 40 is provided between the outer tailgate panel 11 and the inner tailgate panel 12. In this way, the aesthetics can be guaranteed, and the connection structure of the spoiler 20 is not exposed when the tailgate 10 is opened.
[0047] Additionally, refer to Figure 1 The inner panel 12 of the tailgate is also provided with a clearance hole 121 for the installation of the support bushing 40 and for the operation of the locking nut 52. The orientation of the clearance hole 121 corresponds to the insertion direction of the fastener 30. In one embodiment, the fastener 30 is inserted from the outer panel 11 of the tailgate to the inner panel 12 in an oblique direction (with oblique component force and vertical force to improve the fixing effect); in other embodiments, different insertion directions can be selected according to different vehicle models.
[0048] Reference Figure 2 , Figure 2 The example shows a spoiler 20 passing through the tailgate 10. Part of the positioning section 31 and fasteners are located inside the outer panel 11 of the tailgate. As can be seen from the figure, the tailgate 10 is also provided with a guide groove 112 for the installation of the support bushing 40 (not shown in the figure). The guide groove 112 is adapted to the support bushing 40 to form a fit. On the one hand, it can play a guiding role in installation, and on the other hand, it can prevent incorrect installation and avoid the problem of incorrect installation.
[0049] Understandably, the guide groove 112 can be provided on the inner side of the outer panel 11 of the tailgate; it can also be provided on the inner panel 12 of the tailgate and recessed towards the outer panel 11 of the tailgate (for example, a recessed platform embedded in the clearance hole 121 facing the inner side of the outer panel 11 of the tailgate, the guide groove 112 is formed on the recessed platform, and a cover plate can be installed to cover it, thereby concealing the clearance hole 121, the support bushing 40 and the fastening structure 50, improving the appearance integration and overall texture).
[0050] Specifically, the fastener 30 includes a positioning section 31 that forms a rotational limiting fit with the inner wall of the mounting hole 111, and a fastening section 32 that extends axially along the positioning section 31. The fastening section 32 is provided with an external thread that mates with the locking nut 52 (i.e., the threaded mating section 51 is provided on the fastening section 32). Figure 2 and Figure 3Part of the positioning section 31 and the fastening section 32 pass through the outer panel 11 of the tailgate. The outer panel 12 of the tailgate has a clearance hole 121, which provides operating space for the 40 sets of positioning sections 31 of the support bushings and for the fastening nut 52 to be screwed into the fastening section 32. Figure 1 The locking nut 52 is screwed to the fastening section 32, and the support bushing 40 is locked to the outer panel 11 of the tailgate. Thus, after the locking nut 52 is fastened to the fastening section 32, it can provide a counter-support force under the action of the locking nut 52, so that the spoiler 20 is attached and fixed to the tailgate 10.
[0051] Reference Figure 3 In this embodiment, the cross-section of the positioning segment 31 is a polygonal prism structure, and the mounting hole 111 is adapted to the prism structure, such as a raindrop-shaped irregular prism structure or a triangular prism, a quadrangular prism, a pentagonal prism, etc.
[0052] In other embodiments, a positioning boss may be provided in the mounting hole 111, and a positioning groove may be provided in the positioning section 31, so that circumferential positioning can be achieved after insertion.
[0053] Combination Figure 1 and Figure 3 For easier fixation, in this embodiment, the fixing member 30 further includes a fastening section 32 extending downward from the self-positioning section 31. The support bushing 40 is provided with a clearance through hole for the fastening section 32 to pass through. The fastening structure 50 includes a threaded section 51 and a locking nut 52 corresponding to the threaded section 51. Specifically, the threaded section 51 is configured to have external threads on the fastening section 32. The locking nut 52 is connected to the fastening section 32 and cooperates with the support bushing 40 to form an axial pre-tightening limit.
[0054] Specifically, the outer diameter of the fastening section 32 is smaller than the outer diameter of the positioning section 31, forming a stepped structure on the fixing member 30. In order to avoid the rotation of the support bushing 40, the support bushing 40 is provided with a relief groove 41 that matches the shape of the positioning section 31. The inner wall of the relief groove 41 and the outer wall of the positioning section 31 form a rotation limiting fit.
[0055] Of course, in other solutions, a groove can be provided on the support bushing 40 and a corresponding sliding rail can be provided on the positioning section 31; understandably, the groove and the sliding rail can also be provided in opposite directions.
[0056] To ensure a more stable fit for the support bushing 40, the bottom contour of the support bushing 40 is adapted to the inner surface contour of the tailgate 10, forming a surface-contact fitting assembly. Specifically, the support bushing 40 is a cylindrical sleeve, with its bottom conforming to the inner surface of the tailgate 10, i.e., the inner surface contour of the tailgate outer panel 11. A clearance groove 41 is formed inside the sleeve to match the positioning section 31, which serves to guide the installation with the positioning section 31 and also restricts the rotation of the support bushing 40.
[0057] Understandably, the depth of the relief groove 41 of the support bushing 40 is greater than or equal to the insertion depth of the positioning section 31 into the inner surface of the tailgate outer panel 11, so that the support bushing 40 can contact the contour surface of the inner surface of the tailgate outer panel 11.
[0058] In addition, the end of the support bushing 40 away from the outer panel 11 of the back door is provided with a through hole 42 that connects to the relief groove 41. The through hole 42 is used for the fastening section 32 to pass through so that the locking nut 52 can be fixed.
[0059] This utility model also proposes a vehicle that includes the above-described spoiler mounting structure. Since the vehicle adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.
[0060] 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.
