[0025] In the figure: inner plate body 1; extruded rubber strip 2; main body part 211; hook semi-circular ring part 212; elastic space 213; bright strip 3; claw 311; bending part 312; coupling part 4; first connection part 411; second connection part 412; transition connection part 413; protruding block 5; uniform rib 6; pre-positioning part 7; foam pad 8; buckle seat 9; installation opening 10; anti-disengagement part 11; elastic sheet 12; top sheet metal head 13; installation groove 14; abutting platform 15; edge clamping fitting 16; double-sided clamping shoulder 17.

[0026] As Figure 1 and Figure 2 shown, this two-color injection molded automotive rear spoiler decorative panel includes an inner plate body 1, an extruded rubber strip 2, and a bright strip 3. The bright strip 3 is installed on the outer surface of the inner plate body 1. The extruded rubber strip 2 is located on the right side and upper side of the inner plate body 1. A coupling part 4 is provided between the right side of the inner plate body 1 and the extruded rubber strip 2. The coupling part 4 is a hard rubber, and the extruded rubber body is a soft rubber. In this embodiment, the inner plate body 1 and the coupling part 4 are made of PP+GF hard rubber plastic, and the extruded rubber strip 2 is made of TPE soft rubber. The coupling part 4 is integrally in an I shape, including a first connection part 411, a second connection part 412, and a transition connection part 413. The first connection part 411 is in close connection with the extruded rubber strip 2. After passing through the transition connection part 413, the first connection part 411 is connected to the second connection part 412. The second connection part 412 is in close connection with the inner plate body 1. Here, the coupling part 4 of this patent is equivalent to a mushroom nail reverse buckle design, ensuring the bonding force between the hard rubber and the soft rubber in the two-color injection molding of plastics (preventing pulling off and tearing), as Figure 3And Figure 4 As shown, a protruding block 5 is provided on the extruded rubber strip 2, which can avoid the problems of difficult assembly and abnormal noise between the hard rubber and the bright strip 3. A row of uniform ribs 6 is provided on the extruded rubber strip 2, which ensures the local contact structure between the stainless steel bright strip 3 and the extruded rubber strip 2, facilitates the modification of the clearance for the cooperation of the extruded rubber strip 2, eliminates noise, and solves the problems of easy generation of abnormal noise and difficult assembly.

[0027] As Figure 4 And Figure 8 shown, as an optimization, a pre-positioning part 7 is provided on the inner surface of the inner plate body 1. Here, through the pre-positioning part 7, pre-positioning can be carried out first during installation, ensuring the accuracy of subsequent fixation. The pre-positioning part 7 is in a cross shape, and a circle of foam pads 8 is provided on the circumference of the pre-positioning part 7. Here, through the structure of the foam pads 8, the achievement of the waterproof performance of the whole product is ensured. A buckle seat 9 is provided beside the pre-positioning part 7. The buckle seat 9 has an installation opening 10, and an anti-disengagement part 11 is provided on the side of the installation opening of the buckle seat 9. Here, through the anti-disengagement part 11, on the one hand, it is convenient to install the buckle, and on the other hand, it prevents disengagement through the anti-disengagement part 11, avoiding the risk of the buckle falling off during transportation and during on-line vehicle loading. Especially for international project sea transportation, the product bumps on the sea, and the buckle shakes back and forth in the buckle seat 9, and usually it is easy to fall off during transportation. A spring piece 12 is provided on the installation opening 10, and top sheet metal heads 13 are provided on both sides of the installation opening 10. The present invention adds the relevant spring piece 12 structure, effectively preventing the problem of the rib buckle from disengaging. When the spoiler assembly is loaded onto the vehicle, in the case of a relatively large torque of the automatic screw gun on the main engine factory assembly line, because the bolt is a rigid surface, while the buckle seat 9 is made of plastic material, and the mating part sheet metal is thin steel, when performing high-torque operations, it is easy to push out the trace of the bolt surface. The top sheet metal heads 13 are used to avoid pulling out dents on the appearance A surface, and at the same time, the strength of the buckle seat 9 is also improved.

[0028] As a further optimization, as Figure 5 And Figure 6 shown, the extruded rubber strip 2 on the upper side has an installation groove 14, and the bright strip 3 has a claw 311. The claw 311 is stuck at the installation groove 14 for positioning and installation. At the same time, after buckling, the connection reliability between the soft rubber and the hard rubber can also be improved, ensuring the streamlined shape during vehicle loading and the improvement of the installation efficiency in the factory. The inner plate body 1 has a abutting platform 15, and the claw 311 of the bright strip 3 has a bent part 312. After being bent 90 degrees, the bent part 312 abuts against the abutting platform 15. In this way, it can not only limit the claw 311, but also ensure the supporting performance of the abutting platform 15, and solve the problem of easy deformation due to insufficient rigidity of the inner plate body 1 during bending.

[0029] A glue reduction structure is provided on the side of the inner plate body 1 of the automotive rear spoiler decorative panel, ensuring that the platform will not shrink, thus affecting the tolerance of the assembly surface matching. This avoids problems such as shrinkage and resulting depressions during cooling, which can affect the assembly accuracy and also easily generate tensile stress on the product (twisting problems during thermal cycling). By setting relevant hollowing structures, relevant shrinkage problems can be effectively prevented, such as Figure 7 shown. As an optimization, the cross-section of the extruded rubber strip 2 includes an integrally formed main body portion 211 and a hooked semi-circular ring portion 212. The hooked semi-circular ring portion 212 has an elastic space 213. The elastic space 213 ensures the gap compensation, deformation resilience performance, and space between the extruded rubber strip 2 and the mating part. Previously, the general extruded rubber strip 2 had a common rectangular extruded cross-section without any deformation space. When the hardness of the material is relatively high, there is no space for deformation and resilience. Thus, when lapping with the mating part, it cannot deform to absorb relevant manufacturing and assembly tolerances, such as Figure 9 shown. On the left side edge of the inner plate body 1, there is a side part fitting 16. The engaging head of the fitting is a two-way engaging shoulder 17, making the force more uniform and ensuring the balance of the assembly.

[0030] The specific embodiments described in this text are merely illustrative of the spirit of the present invention. Those skilled in the art of the present invention can make various modifications, supplements, or use similar ways to replace the described specific embodiments, but will not deviate from the scope defined by the spirit of the present invention.
