Description

Technical Field

[0001] This invention relates to the field of automotive spoiler technology, and more specifically to an automotive spoiler assembly, a vehicle, and a method for processing the automotive spoiler assembly. Background Technology

[0002] Automotive spoilers are typically mounted on the rear of a vehicle, providing downforce at high speeds to improve stability and handling. Most existing automotive spoilers are made entirely of plastic and assembled using snap-fit ​​methods. To meet the rigidity requirements of these spoilers, extensive reinforcement structures are often needed, leading to increased weight. Furthermore, the all-plastic finish results in high costs for subsequent painting and other finishing processes.

[0003] To address these issues, some automotive spoilers have begun using components made of different materials to meet demands for lightweighting or diverse appearances. However, due to the significant differences in the coefficients of thermal expansion of different materials, the expansion and contraction properties of each component vary with temperature changes. This can easily lead to thermal stress at component joints and mating interfaces, especially on the exterior surfaces, resulting in problems such as uneven light and shadow, surface differences, or visual irregularities, thus affecting the overall appearance quality of the vehicle. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the purpose of this application is to provide an automotive spoiler assembly, a vehicle, and a processing method for the automotive spoiler assembly, which aims to solve the problem in the prior art that automotive spoiler components made of different materials are prone to uneven light and shadow, surface differences, or visual unevenness due to thermal stress, which affects the overall appearance quality of the vehicle.

[0005] In a first aspect, embodiments of this application provide an automotive spoiler assembly, comprising: A skeleton, on which a first connecting structure is provided; The outer panel is provided with a second connecting structure connected to the first connecting structure, and the outer panel is made of a different material than the frame; A colloid receiving portion is disposed in at least one of the frame and the outer plate, the colloid receiving portion being used to receive colloid so as to bond the frame and the outer plate together.

[0006] Therefore, a composite connection method combining mechanical and adhesive connections is formed between the frame and the outer panel. This not only improves the connection strength between the frame and the outer panel, but also forms a flexible connection layer between them. When the temperature changes, the relative displacement between the frame and the outer panel can be absorbed by the flexible connection layer through its own deformation. The flexible buffer of the adhesive can coordinate the difference in thermal expansion between the two, which can effectively reduce the problems that affect the overall appearance quality of the vehicle, such as uneven light and shadow, surface differences, or visual unevenness, caused by thermal stress between the outer panel and the frame. This is beneficial to improving the appearance quality of the automotive spoiler assembly.

[0007] In some embodiments, the colloid receiving portion includes a colloid groove disposed in at least one of the skeleton and the outer plate, the colloid groove extending circumferentially along the outer plate, and the colloid being received in the colloid groove.

[0008] Therefore, the adhesive groove extends circumferentially along the outer panel, which can define the distribution area, thickness, and boundaries of the adhesive. During application or injection of adhesive, the adhesive is confined within the adhesive groove, preventing it from overflowing into non-bonded areas or the outer surface. Furthermore, after the frame and outer panel are assembled, the adhesive spreads evenly within the adhesive groove, and after curing, forms an adhesive layer with stable thickness and clear boundaries, thereby achieving reliable bonding strength between the frame and the outer panel.

[0009] In some embodiments, multiple adhesive grooves are provided, and the multiple adhesive grooves are spaced apart along the circumference of the outer panel.

[0010] Therefore, by setting the adhesive groove into multiple segments, with intervals between adjacent grooves, these intervals serve as stress release spaces. This allows the adhesive in each groove to shrink independently during curing, preventing the continuous accumulation of shrinkage stress along the circumference of the outer panel. This reduces the risk of localized warping and surface defects in the outer panel due to internal curing stress. Simultaneously, multiple evenly distributed bonding points or areas are formed between the frame and the outer panel. While ensuring sufficient bonding strength, this reduces the continuous constraint of the continuous adhesive layer on the outer panel. This allows the multiple segmented, independent adhesive layers to absorb the relative displacement between the frame and the outer panel through their own deformation, effectively preventing uneven surface lighting on the outer panel due to internal stress accumulation. This fundamentally improves the dimensional stability and appearance quality of the product across a wide temperature range.

[0011] In some embodiments, the colloid receiving portion further includes a baffle rib, which is disposed around the opening of the colloid groove.

[0012] Therefore, the glue-blocking ribs can form a barrier boundary around the opening of the glue tank. When the glue is contained in the glue tank and the outer panel is assembled, the glue is squeezed by the outer panel and spreads in the glue tank. The glue-blocking ribs can prevent the glue from flowing out of the opening and confining the glue to the glue tank and its opening, thus avoiding surface contamination caused by glue overflow.

[0013] In some embodiments, the adhesive-blocking rib is provided with an overflow groove communicating with the slot, and at least one overflow groove is provided.

[0014] Therefore, the adhesive baffle and the adhesive overflow channel work together to not only prevent the turbulence of the adhesive, but also provide a controlled discharge path for excess adhesive, thereby improving the stability and consistency of the bonding quality.

[0015] In some embodiments, the first connecting structure includes a slot and a first snap-fit ​​portion. The slot is disposed on the skeleton for the insertion of the second connecting structure. The slot includes two opposing groove walls, one of which is provided with the first snap-fit ​​portion. The second connecting structure is correspondingly provided with a second snap-fit ​​portion, and the first snap-fit ​​portion snaps into the second snap-fit ​​portion.

[0016] Thus, through the cooperation of the slot, the first snap-fit ​​part and the second snap-fit ​​part, a reliable mechanical connection is formed between the frame and the outer plate.

[0017] In some embodiments, one of the first latching portion and the second latching portion is a latching protrusion, and the other is a latching hole that latches with the latching protrusion.

[0018] Therefore, when the second connecting structure is inserted into the first connecting structure, the first locking part and the second locking part engage to achieve reliable positioning.

[0019] In some embodiments, the first connecting structure further includes a limiting member disposed on another groove wall, and the second connecting structure is limited between the limiting member and the first snap-fit ​​portion.

[0020] Therefore, during the insertion of the second connecting structure into the slot, the limiting member can guide and constrain the insertion direction of the second connecting structure, allowing it to smoothly reach the position that mates with the first snap-fit ​​part along the slot, reducing offset and jamming during assembly. Furthermore, after the second snap-fit ​​part engages with the first snap-fit ​​part, the limiting member and the first snap-fit ​​part are located on opposite sides of the second connecting structure, respectively, thus limiting the second connecting structure and restricting it from shaking, tilting, or retreating within the slot, thereby improving the mechanical connection stability and positioning accuracy between the frame and the outer plate.

[0021] In some embodiments, the limiting member has a guide ramp for engaging the second connecting structure into the slot.

[0022] Therefore, the guide slope on the limiting member can abut against the second connecting structure when it is inserted into the slot, and decompose the insertion force into a guide force, guiding the second connecting structure to slide smoothly towards the first snap-fit ​​part in a predetermined direction.

[0023] In some embodiments, a window is provided at the bottom of the slot, and the window is located below the first latching portion.

[0024] Therefore, the window can serve as a weight-reducing hole to decrease the overall weight of the skeleton, and also facilitate core pulling or demolding during skeleton injection molding, reducing molding difficulty and mold complexity. Simultaneously, the window can also serve as a visual inspection channel for the engagement status of the first and second snap-fit ​​parts.

[0025] Secondly, embodiments of this application provide a vehicle, including a vehicle body and the aforementioned vehicle spoiler assembly, wherein the vehicle spoiler assembly is disposed on the vehicle body.

[0026] Thirdly, embodiments of this application provide a method for processing an automotive spoiler assembly, used to process the aforementioned automotive spoiler assembly, the processing method comprising: Obtain the skeleton and outer plate; Inject colloid into the colloid container; Assemble the skeleton with the outer plate and wait for the colloid to cure.

Detailed Implementation

[0030] The terms "first," "second," etc., are used for descriptive purposes only and have no sequential or technical meaning, nor should they be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Directional terms used in this application, such as "upper," "lower," "front," "rear," "left," "right," "inner," and "outer," are merely for reference to the orientation shown in the accompanying drawings. The use of directional terms is for better and clearer explanation and understanding of this application, and does not indicate the orientation of the referred device or component in an actual application scenario.

[0031] In the description of the embodiments of this application, unless otherwise expressly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. "Fixed connection" refers to a connection where the relative positional relationship remains unchanged after connection. "Rotary connection" refers to a connection where the two parts can rotate relative to each other after connection. "Sliding connection" refers to a connection where the two parts can slide relative to each other after connection.

[0032] In the embodiments of this application, "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.

[0033] The terms "parallel" and "perpendicular" are relative to the current technological level, not absolute mathematical definitions. Slight deviations are permissible; approximations of parallelism or perpendicularity are acceptable. For example, "A and B are parallel" means that A and B are parallel or approximately parallel, with the angle between them ranging from 0 to 5 degrees. Similarly, "A and B are perpendicular" means that A and B are perpendicular or approximately perpendicular, with the angle between them ranging from 85 to 95 degrees.

An electrical connection between A and B means that current or signal can flow from A to B and vice versa. This connection includes direct and indirect electrical connections. A direct electrical connection between A and B means that A and B are physically connected. An indirect electrical connection between A and B means that A and B are connected via C, where C can be at least one wire or device.

[0035] The embodiments of this application are described below with reference to the accompanying drawings.

[0036] Please see Figure 1 , Figure 1 This is a schematic diagram of the vehicle structure disclosed in the embodiments of this application. The vehicle can be, but is not limited to, a pure electric vehicle (PEV / BEV), a hybrid electric vehicle (HEV), a range-extended electric vehicle (REEV), a plug-in hybrid electric vehicle (PHEV), or a new energy vehicle.

[0037] In this embodiment, the vehicle includes a body body 100 and a spoiler assembly disposed on the body body 100. The spoiler assembly is located at the rear of the body body 100. Please refer to [link / reference]. Figure 2 and Figure 3 , Figure 2 This is a structurally exploded view of the automotive spoiler assembly disclosed in an embodiment of this application. Figure 3This is a schematic diagram of the structure of an automotive spoiler assembly disclosed in an embodiment of this application. The automotive spoiler assembly includes a frame 1, an outer panel 2, and a glue-receiving portion 3. The frame 1 is provided with a first connecting structure 11, and the outer panel 2 is provided with a second connecting structure 21 connected to the first connecting structure 11. The outer panel 2 and the frame 1 are made of different materials. The glue-receiving portion 3 is provided in at least one of the frame 1 and the outer panel 2, and is used to contain glue, which bonds the frame 1 and the outer panel 2 together.

[0038] For example, such as Figure 1 As shown, in this embodiment, the colloid receiving portion 3 is disposed on the frame 1, which can accommodate the colloid, allowing the frame 1 and the outer panel 2 to be bonded together. Thus, in this embodiment, a composite connection combining mechanical and adhesive bonding is formed between the frame 1 and the outer panel 2. This not only improves the connection strength between the frame 1 and the outer panel 2 but also forms a flexible connecting layer between them. When the temperature changes, the relative displacement between the frame 1 and the outer panel 2 can be absorbed by the flexible connecting layer through its own deformation, reducing the risk of uneven light and shadow. Therefore, even when the frame 1 and the outer panel 2 are made of different materials, the adhesive bonding not only achieves further reliable fixation between the frame 1 and the outer panel 2 but also coordinates the difference in thermal expansion between the two through the flexible buffer of the colloid. This allows the automotive spoiler assembly to balance connection reliability and appearance quality in a wide temperature range environment, effectively reducing the risk of uneven light and shadow on the outer panel 2 and improving the appearance quality of the automotive spoiler assembly.

[0039] The location of the colloid receiving part 3 in this embodiment includes, but is not limited to: being provided only on the skeleton 1, being provided only on the outer plate 2, or having the colloid receiving part 3 provided on both the skeleton 1 and the outer plate 2. The appropriate location can be selected based on the actual situation. (This embodiment is attached.) Figure 2 Taking the example of the colloid container 3 being located on the skeleton 1, it does not mean that the colloid container 3 can only be located on the skeleton 1.

[0040] In this embodiment, the skeleton 1 and the outer panel 2 are made of different materials. For example, the skeleton 1 in this embodiment is an injection-molded skeleton, which can be made of high-heat-resistant PC+ABS material, that is, a mixture of polycarbonate (PC) and acrylonitrile-butadiene-styrene copolymer (ABS), with a heat distortion temperature (HDT) ≥ 105℃, combining the high strength and heat resistance of PC with the easy processing of ABS. The outer panel 2 in this embodiment is made of high-strength steel plate or 5000 series aluminum alloy plate with a thickness of 0.5mm to 0.8mm by stamping. The colloid container 3 can be directly integrally molded onto the skeleton 1, injection molded integrally with the skeleton 1.

[0041] In other embodiments, the vehicle spoiler assembly may also include a side trim piece 4, a brake light 5, a foam strip 6, and a lower spoiler baffle 7. For example... Figure 3 and Figure 4 As shown, Figure 3 This is a schematic diagram of the structure of the automotive spoiler assembly disclosed in the embodiments of this application. Figure 4 This is a schematic cross-sectional view of the assembly of the car spoiler assembly and the main body of the vehicle disclosed in this application. Two side trim pieces 4 are provided, each connected to both ends of the frame 1 to form a smooth linear shape of the car spoiler assembly. Brake lights 5 are mounted on the frame 1. The outer panel 2 and the lower baffle 7 are respectively provided with clearance areas for the brake lights 5 to be exposed. The brake lights 5 are electrically connected to the main body 100 to be illuminated when the driver brakes, serving as a warning to vehicles behind. The lower baffle 7 is connected to the lower part of the frame 1. A sponge strip 6 is placed between the lower baffle 7 and the rear windshield of the main body 100, enhancing sealing and preventing hard contact between the lower baffle 7 and the rear windshield of the main body 100. The frame 1 is directly fixed to the main body 100 using bolts or other fasteners. The side trim pieces 4, brake lights 5, and the lower baffle 7 of the spoiler are also made of high-heat-resistant PC+ABS material. The outer surface of the car spoiler assembly is all spray-coated, divided into areas of the same color as the body and high-gloss black areas according to the design. Understandably, since the lower baffle 7 is located below the frame 1 and is not easily noticeable, while the outer panel 2 is located above the frame 1, problems such as uneven lighting, surface differences, or visual irregularities on the outer panel 2 will directly affect the overall appearance quality of the vehicle. Therefore, this application preferably uses a composite connection method combining mechanical and adhesive connections between the outer panel 2 and the frame 1. In other embodiments, a composite connection method combining mechanical and adhesive connections can also be used between the lower baffle 7 and the frame 1, without being limited to the figures shown in this embodiment, and can be selected according to the actual situation.

[0042] Furthermore, the colloid receiving portion 3 of this embodiment includes a glue groove 31 disposed in at least one of the frame 1 and the outer plate 2. The glue groove 31 extends circumferentially along the outer plate 2, and the colloid is received within the glue groove 31. For details, please refer to... Figure 5 and Figure 6 , Figure 5 This is a partial structural diagram of the skeleton 1 disclosed in an embodiment of this application. Figure 6 for Figure 5A partially enlarged schematic diagram at point A. In this embodiment, the colloid receiving portion 3 includes a colloid groove 31, which is disposed on the side of the skeleton 1 facing the outer plate 2 and extends circumferentially along the outer plate 2. The groove opening 311 of the colloid groove 31 faces the outer plate 2, and the colloid is contained within the colloid groove 31. When the outer plate 2 and the skeleton 1 are connected by the first connecting structure 11 and the second connecting structure 21, the colloid fills the colloid groove 31 and contacts the surface of the outer plate 2. After curing, a circumferentially extending colloid layer is formed between the skeleton 1 and the outer plate 2. Thus, the colloid groove 31, extending circumferentially along the outer plate 2, can define the distribution area of ​​the colloid, the thickness of the colloid layer, and its boundaries. During application or injection of colloid, the colloid is confined within the colloid groove 31, preventing it from overflowing into non-bonded areas or the outer surface. After the skeleton 1 and the outer plate 2 are assembled, the colloid spreads evenly within the colloid groove 31, and after curing, forms a stable-thickness colloid layer with clear boundaries, thereby achieving reliable bonding strength between the skeleton 1 and the outer plate 2. Since the glue groove 31 extends circumferentially, the glue layer can be continuously distributed along the circumferential direction of the outer plate 2, making the bonding constraint between the skeleton 1 and the outer plate 2 more uniform along the circumferential direction. When the temperature changes, the free expansion or contraction of the outer plate 2 and the skeleton 1 are different. The glue layer extending circumferentially is located between the two and can undergo shear deformation, thereby buffering the relative displacement between the two.

[0043] Furthermore, multiple glue channels 31 are provided, and the multiple glue channels 31 are spaced apart along the circumference of the outer panel 2. For details, please refer to [link / reference]. Figure 5 , Figure 5 This is a partial structural diagram of the skeleton 1 disclosed in an embodiment of this application. In this embodiment, multiple glue channels 31 are provided, each segment of which is approximately 30mm-60mm long and spaced approximately 50mm apart. These multiple glue channels 31 are spaced apart along the circumference of the outer panel 2. Thus, by setting the glue channels 31 into multiple segments, an interval region is formed between adjacent glue channels 31. This interval region can serve as a stress release space, allowing the adhesive in each glue channel 31 to shrink independently during the curing process, avoiding the continuous accumulation of shrinkage stress along the circumference of the outer panel 2. This reduces the risk of localized warping and surface defects in the outer panel 2 due to curing internal stress. Meanwhile, the glue grooves 31 are spaced apart along the circumference, forming multiple evenly distributed bonding points or bonding areas between the skeleton 1 and the outer panel 2. While ensuring sufficient bonding strength, the continuous constraint of the continuous glue layer on the outer panel 2 is reduced, allowing multiple segmented independent glue layers to absorb the relative displacement between the skeleton 1 and the outer panel 2 through their own deformation. This effectively avoids uneven light and shadow on the surface of the outer panel 2 due to the accumulation of internal stress, fundamentally improving the dimensional stability and appearance quality of the product in a wide temperature range environment.

[0044] Furthermore, the colloid receiving portion 3 also includes a baffle 32, which is disposed around the opening 311 of the glue tank 31. For details, please refer to [link to relevant documentation]. Figure 6 and Figure 7 , Figure 6 for Figure 5A magnified view of a portion of point A in the diagram. Figure 7 for Figure 5 A schematic diagram showing the connection between the skeleton 1 and the outer plate 2 at point AA. In this embodiment, a glue-blocking rib 32 is provided around the opening 311 of the glue tank 31. The glue-blocking rib 32 can form a blocking boundary around the opening 311 of the glue tank 31. When the glue is contained in the glue tank 31 and the outer plate 2 is assembled, the glue is squeezed by the outer plate 2 and spreads in the glue tank 31. The glue-blocking rib 32 can prevent the glue from flowing outward across the opening 311, so that the glue is confined in the glue tank 31 and near the opening 311, avoiding surface contamination caused by glue overflow.

[0045] Furthermore, the adhesive-blocking rib 32 is provided with an overflow groove 321 communicating with the slot 311, and at least one overflow groove 321 is provided. For details, please refer to... Figure 6 and Figure 7 , Figure 6 for Figure 5 A magnified view of a portion of point A in the diagram. Figure 7 for Figure 5 A schematic diagram showing the connection between the skeleton 1 and the outer panel 2 at point AA. When adhesive is applied into the glue tank 31 and the outer panel 2 is assembled with the skeleton 1, the adhesive flows towards the opening 311 within the glue tank 31 due to the pressure from the outer panel 2. The adhesive baffle 32 prevents the adhesive from overflowing uncontrollably, while the overflow groove 321, connected to the opening 311, provides a controlled overflow channel for excess adhesive. Excess adhesive can enter the overflow groove 321 through the opening 311 and be temporarily stored and cured there, thus preventing uncontrolled overflow of adhesive from other positions of the adhesive baffle 32 into the non-bonded area between the skeleton 1 and the outer panel 2 or onto the outer surface of the outer panel 2. The number of overflow grooves 321 can be set according to the length of the glue tank 31, the amount of adhesive applied, and the required adhesive layer thickness to ensure that the glue tank 31 is full but not excessive. That is, the adhesive-blocking rib 32 and the adhesive overflow groove 321 work together to both prevent turbulent flow of adhesive and provide a controlled discharge path for excess adhesive, thereby improving the stability and consistency of bonding quality. In this embodiment, the adhesive overflow groove 321 is preferably located on the side of the adhesive-blocking rib 32 away from the first connecting structure 11. When excess adhesive overflows through the adhesive overflow groove 321, it flows away from the first connecting structure 11 and is temporarily stored, preventing the adhesive from flowing towards the first connecting structure 11 and affecting the mating connection between the first connecting structure 11 and the second connecting structure 21.

[0046] Taking this embodiment as an example, the glue groove 31 in this embodiment is a trapezoidal cross-section groove integrated on the skeleton 1. The upper width K of the glue groove 31 is 3mm-5mm, the lower width L of the glue groove 31 is 2mm-4mm, and the depth M of the glue groove 31 is 0.8mm-1.2mm. There is a gap of 0.3mm-0.5mm between the glue-blocking rib 32 and the outer plate 2 to guide the excess glue in the glue groove 31 into the overflow glue groove 321. The overflow glue groove 321 has a depth of 0.5mm and a width of 0.5mm-2mm and is used to discharge the overflowed glue.

[0047] Furthermore, to better release stress, the colloid used in this embodiment is a low-modulus flexible structural adhesive, preferably polyurethane or modified toughened epoxy, with a tensile modulus of elasticity of 300MPa to 1200MPa below 23°C, an elongation at break ≥25%, and a shear strength ≥12MPa, to meet the stringent requirements of the operating environment. During the curing of this type of colloid, the relative humidity of the air needs to be controlled at 40% to 60%; the curing time is calculated from the moment the core temperature of the colloid reaches the target temperature.

[0048] Optionally, the first connection structure 11 in this embodiment includes a slot 111 and a first snap-fit ​​portion 112. See also... Figure 7 and Figure 8 , Figure 7 for Figure 5 A schematic diagram showing the connection between the frame 1 and the outer plate 2 at point AA. Figure 8 for Figure 5 A schematic diagram of the connection between the frame 1 and the outer plate 2 at the middle BB. The slot 111 is provided on the frame 1 for the insertion of the second connecting structure 21. The slot 111 includes two oppositely arranged slot walls. One of the slot walls is provided with a first snap-fit ​​part 112. The second connecting structure 21 is provided with a corresponding second snap-fit ​​part 221. The first snap-fit ​​part 112 and the second snap-fit ​​part 221 snap together.

[0049] Therefore, in this embodiment, the cooperation of the slot 111, the first engaging part 112, and the second engaging part 221 enables a reliable mechanical connection between the frame 1 and the outer plate 2. The slot 111, located on the frame 1, provides insertion space and guidance for the second connecting structure 21, allowing the outer plate 2 to be quickly aligned with the frame 1 during assembly. The two opposing groove walls of the slot 111 can limit the second connecting structure 21 from both sides, constraining the lateral movement and wobbling of the outer plate 2 relative to the frame 1, thus improving the accuracy of the assembly position. The first engaging part 112, located on one of the groove walls, engages with the second engaging part 221 on the second connecting structure 21, forming a backstop constraint in the insertion direction of the slot 111, preventing the second connecting structure 21 from dislodging from the slot 111, thereby ensuring the reliability of the connection between the frame 1 and the outer plate 2.

[0050] Furthermore, in the first latching portion 112 and the second latching portion 221, one is a latching protrusion, and the other is a latching hole that engages with the latching protrusion. For details, please refer to [link to relevant documentation]. Figure 7 , Figure 7 for Figure 5 The diagram shows the connection between the frame 1 and the outer plate 2 at point AA. In this embodiment, the first locking part 112 is a locking protrusion, and the second locking part 221 is a locking hole. When the second connecting structure 21 is inserted into the first connecting structure 11, the first locking part 112 and the second locking part 221 engage to achieve reliable positioning. Furthermore, in other embodiments, the first locking part 112 can be a locking hole, and the second locking part 221 can be a locking protrusion, which can also achieve the above purpose. The appropriate design choice depends on the actual situation.

[0051] Furthermore, the first connecting structure 11 also includes a limiting member 113, which is disposed on another groove wall, and the second connecting structure 21 is confined between the limiting member 113 and the first snap-fit ​​portion 112. For details, please refer to... Figure 8 , Figure 8 for Figure 5 A schematic diagram of the connection between the skeleton 1 and the outer plate 2 at point BB. A limiting member 113 is provided in the slot 111. The limiting member 113 is located on the groove wall of another slot 111 opposite to the first snap-fit ​​part 112. During the insertion of the second connecting structure 21 into the slot 111, the limiting member 113 can guide and constrain the insertion direction of the second connecting structure 21, so that it can smoothly reach the position to cooperate with the first snap-fit ​​part 112 along the slot 111, reducing the offset and jamming during assembly. After the second snap-fit ​​part 221 is engaged with the first snap-fit ​​part 112, the limiting member 113 and the first snap-fit ​​part 112 are located on opposite sides of the second connecting structure 21, respectively, forming a limit on the second connecting structure 21, restricting it from shaking, tilting or retreating in the slot 111, thereby improving the mechanical connection stability and positioning accuracy between the skeleton 1 and the outer plate 2.

[0052] Furthermore, the limiting member 113 has a guide slope 1131 for accommodating the second connecting structure 21 when inserted into the slot 111. Specifically, please refer to... Figure 8 , Figure 8 for Figure 5 A schematic diagram showing the connection between the skeleton 1 and the outer plate 2 at point BB. The guide slope 1131 on the limiting member 113 can abut against the second connecting structure 21 when it is inserted into the slot 111, and decompose the insertion force into a guiding component, guiding the second connecting structure 21 to slide smoothly towards the first snap-fit ​​part 112 in a predetermined direction. Even if there is a certain positional or angular deviation between the outer plate 2 and the skeleton 1 during assembly, the guide slope 1131 can also correct the insertion direction of the second connecting structure 21 through the slope engagement, which helps to improve assembly efficiency and assembly consistency.

[0053] For example, in this embodiment, the second connecting structure 21 is a flanged structure. The height S of the second connecting structure 21 is 10mm-15mm. Locking holes are arranged every 80mm-100mm along the length of the second connecting structure 21. The length of each locking hole is 12mm, the width H is 8mm, and the edge distance J of the locking holes is ≥5mm. The engagement amount P between the locking protrusion and the locking hole is ≥1.5mm, the interference amount N is 0.1mm-0.3mm, and the holding force of a single locking point is 40N to 60N. The overlap Q between the limiting member 113 and the second connecting structure 21 is greater than 3.5mm, and the gap R between the second connecting structure 21 and the limiting rib is 0.2mm-0.5mm. Therefore, the gap setting and appropriate interference at each connection point of the first connecting structure 11 and the second connecting structure 21 ensure that the mechanical connection maintains reliable positioning and anti-disengagement functions while also possessing appropriate flexibility, avoiding excessive thermal stress caused by completely rigid constraints during temperature changes. The gap at the mechanical connection allows the second connecting structure 21 to undergo slight displacement between the limiting member 113 and the first snap-fit ​​part 112, preventing the rigid snap-fit ​​part from directly bearing all the thermal deformation difference. At the same time, the colloid absorbs the remaining relative displacement through its own deformation buffer, making the outer plate 2 less prone to warping, surface defects, and uneven surface lighting in a wide temperature range environment, thus balancing connection reliability, assembly stability, and appearance quality. In order to further prevent the first connecting structure 11 and the second connecting structure 21 from being deformed or making abnormal noise due to temperature, this embodiment sets the gap T between the second connecting structure 21 and the slot 111 to 0.5mm. In addition, boss support structures 12 can be set on the frame 1 at intervals of 80mm-100mm, with a 0.5mm gap between the boss support structure 12 and the outer plate 2. This gap can be made of felt to block abnormal noise and provide buffering.

[0054] Optionally, a window 1111 is provided at the bottom of the slot 111, and the window 1111 is located below the first latching portion 112. For details, please refer to... Figure 6 , Figure 6 for Figure 5The enlarged view at point A shows a window 1111 at the bottom of slot 111. Window 1111 serves two purposes: it acts as a weight-reduction hole to reduce the overall weight of the frame 1, and it facilitates core removal or demolding during injection molding of the frame 1, reducing molding difficulty and mold complexity. Simultaneously, window 1111 also serves as a visual inspection channel for the engagement status of the first snap-fit ​​part 112 and the second snap-fit ​​part 221. During assembly, operators or testing equipment can observe through window 1111 whether the first snap-fit ​​part 112 and the second snap-fit ​​part 221 are fully engaged, determining if there are any issues such as missing snap-fit, false snap-fit, insufficient engagement, or the snap protrusion not fully entering the slot. This allows for timely adjustments or rework, preventing loosening of the connection between the frame 1 and the outer plate 2 due to inadequate engagement. During disassembly, tools can be inserted into slot 111 through window 1111, directly acting on the second connecting structure 21 to cause elastic deformation and release the engagement, achieving non-destructive separation of the frame 1 and the outer plate 2, facilitating later maintenance and replacement.

[0055] Experimental testing showed that after 50 temperature cycles from -40℃ to 85℃, the dimensional change at key mounting points of the spoiler assembly in this embodiment was controlled within 0.3mm, far superior to traditional all-plastic solutions (≥1.2mm) or rigid connection solutions (≥0.8mm). Furthermore, bench vibration fatigue testing (SAE J2380 standard) demonstrated that the spoiler assembly in this embodiment achieved a failure cycle count of 2.0 × 10⁻⁶. 6 This is more than twice the standard, far exceeding industry standards. In addition, compared with traditional all-plastic, the overall manufacturing cost of the outer panel 2, which uses sheet metal stamping parts, can be reduced by 25%-35%. If the outer panel 2 is made of high-strength steel or aluminum alloy, a weight reduction of 15%-25% can be achieved under the same rigidity.

[0056] Furthermore, this embodiment also provides a method for processing an automotive spoiler assembly; please refer to [link to relevant documentation]. Figure 9 , Figure 9 The diagram shown is a flowchart of a method for processing an automotive spoiler assembly disclosed in an embodiment of this application. Figure 10 This is a schematic diagram of the production process of the automotive spoiler assembly disclosed in the embodiments of this application.

[0057] The processing method includes: Obtain skeleton 1 and outer plate 2; Specifically, in this step, the joint position between the frame 1 and the outer panel 2 is first determined based on the outer shape of the car spoiler assembly. The portion of the outer shape surface with a curvature R ≥ 150mm belongs to the outer panel 2 (the outer shape surface within this curvature range is relatively flat and easy to form by sheet metal processing), while the portion of the outer shape surface with a curvature R < 150mm belongs to the frame 1 (the outer shape surface within this curvature range is more complex and easier to form by injection molding). At the same time, the joint position between the frame 1 and the outer panel 2 is finally determined based on the final shape.

[0058] The frame 1 is made of high heat-resistant PC+ABS material (i.e., a mixture of polycarbonate PC and acrylonitrile-butadiene-styrene copolymer ABS). After injection molding the frame 1, the frame 1 is assembled with the side trim 4 and other structures. Then, the surfaces of the frame 1 and the side trim 4 are injection molded and sprayed, thus completing the fabrication of the frame 1. The outer panel 2 is made by sheet metal stamping. For the surface treatment of the outer panel 2, this embodiment provides three methods: water-based paint process (for high-end models), powder primer + liquid topcoat composite solution (for mid-to-high-end models), and PCM pre-coated steel plate (for economy models). The appropriate method can be selected according to the actual situation. The water-based paint process in this embodiment includes: pretreatment (silane coating), coating of water-based epoxy primer, flash drying, coating of water-based high-gloss black paint, flash drying, coating of 2K clear coat, low-temperature baking, and inspection, among other steps. The powder primer + liquid topcoat composite solution includes multiple processes such as pretreatment (silane), coating electrostatic powder primer, baking, cooling, coating liquid high-gloss black paint, flash drying, coating 2K clear varnish, baking and inspection. The PCM pre-coated steel sheet includes multiple processes such as PCM coil uncoiling, blanking, stamping, removing protective film, laser cutting / punching, inspection and assembly. The design can be selected according to the actual situation.

[0059] Inject colloid into the colloid container 3; Specifically, in this step, after the skeleton 1 and the outer plate 2 are manufactured, the colloid is injected into the colloid receiving part 3 by a robot. In this embodiment, the colloid is preferably a high-performance two-component polyurethane structural adhesive. The robot injects the colloid into the colloid receiving part 3, which can achieve quantitative and targeted application of the adhesive, and facilitates the consistency of the amount of adhesive in each glue tank 31.

[0060] Assemble and connect the frame 1 and the outer panel 2 and wait for the colloid to cure.

[0061] Specifically, in this step, after the colloid injection is complete, the first connecting structure 11 on the frame 1 is connected to the second connecting structure 21 on the outer panel 2 to achieve pre-assembly of the frame 1 and the outer panel 2. The frame 1 and the outer panel 2 are then pressed and fixed together with a pressure of 20N-30N. At the same time, the colloid is cured by ultraviolet irradiation or heat curing process. Subsequently, the brake light 5, sponge strip 6, and lower spoiler baffle 7 are assembled onto the frame 1 to complete the manufacturing of the automotive spoiler assembly. Finally, it is packaged and stored, and then sent to the final assembly workshop to be assembled as a whole onto the vehicle body 100, completing the manufacturing and assembly of the automotive spoiler assembly.
