Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and more specifically, to a lower trim panel for a rear spoiler of an automobile. Background Technology

[0002] With the development of the automotive industry, consumers have increasingly higher requirements for the appearance and performance of automobiles. The rear spoiler lower trim panel, as an important decorative and functional component of the rear of the car, not only affects the overall aesthetics of the vehicle but also influences its aerodynamic performance to a certain extent. Located at the rear of the car, below the rear spoiler, it is generally installed at the bottom edge of the rear bumper and closely connected to it. However, existing technology has the following shortcomings in its use:

[0003] Traditional rear spoiler trim panels often only meet basic decorative needs, but are insufficient in terms of aerodynamic performance optimization. They cannot effectively guide airflow under the car, resulting in greater lift at the rear of the vehicle when traveling at high speeds, which affects driving stability.

[0004] Therefore, there is an urgent need for a new type of rear spoiler trim panel to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to address the problem that existing traditional automotive rear spoiler trim panels often only meet basic decorative needs, while being insufficient in terms of aerodynamic performance optimization. They cannot effectively guide airflow under the vehicle, resulting in excessive lift at the rear of the vehicle at high speeds, which affects driving stability.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A rear spoiler trim panel for automobiles to improve the above-mentioned problems.

[0008] The application is as follows:

[0009] A rear spoiler lower trim panel for automobiles includes a trim panel body. Two first mounting plates are disposed on one side of the trim panel body, and a second mounting plate is installed between the two first mounting plates. Each of the two first mounting plates is equipped with a first locking pin. Symmetrically distributed second locking pins are installed on the trim panel body. Symmetrically distributed first and second connecting strips are installed on the trim panel body. A third and fourth connecting strips are installed on the first mounting plates, and a fifth connecting strip is installed on the second mounting plate. The lower surface of the trim panel body is an arc-shaped curved surface.

[0010] As a preferred technical solution of this application, the second mounting plate is connected with symmetrically distributed protrusions, and the second mounting plate and the two protrusions are integrally formed.

[0011] As a preferred technical solution of this application, the second mounting plate is provided with symmetrically distributed first mounting holes and a plurality of second mounting holes, with the plurality of second mounting holes located between two first mounting holes.

[0012] As a preferred technical solution of this application, a connecting block is provided at one end of the upper surface of the decorative panel body, a decorative light is installed in the connecting block, the connecting block is located in the middle of the decorative panel body, and the connecting block and the decorative panel body are integrally processed.

[0013] As a preferred technical solution of this application, the two fourth connecting strips are located between the two third connecting strips.

[0014] As a preferred technical solution of this application, the decorative panel body is connected to a plurality of connectors.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] In the scheme of this application:

[0017] 1. The lower surface of the main body of the trim panel is an arc-shaped surface. When airflow passes under the car, the arc-shaped lower surface can guide the airflow to pass more smoothly. Because the arc shape allows the air to flow smoothly along the curved surface, it reduces airflow separation and turbulence, and optimizes the airflow direction.

[0018] 2. The curved lower surface increases the airflow speed through the main body of the trim panel, creating a relatively low pressure zone under the car. This creates a pressure difference with the higher pressure zones around the roof and body, thereby generating downforce, increasing the friction between the vehicle tires and the ground, and improving the stability of the vehicle.

[0030] Example:

[0031] like Figure 1-4As shown, this embodiment proposes a lower trim panel for a car rear spoiler, including a trim panel body 1. Two first mounting plates 2 are disposed on one side of the trim panel body 1, and a second mounting plate 3 is installed between the two first mounting plates 2. First locking pins 4 are installed on each of the two first mounting plates 2. Symmetrically distributed second locking pins 5 are installed on the trim panel body 1. Symmetrically distributed first connecting strips 6 and second connecting strips 7 are installed on the trim panel body 1. Third connecting strips 8 and fourth connecting strips 9 are installed on the first mounting plates 2, and a fifth connecting strip 1 is installed on the second mounting plate 3. 0. The lower surface of the main body of the trim panel is an arc-shaped surface. When the vehicle is in motion, the arc-shaped lower surface can guide the airflow to pass more smoothly as the airflow passes under the vehicle. This is because the arc shape allows the air to flow smoothly along the curved surface, reducing airflow separation and turbulence, and optimizing the airflow direction. At the same time, the arc-shaped lower surface increases the airflow speed through the main body of the trim panel, forming a relatively low pressure zone under the vehicle. This creates a pressure difference with the higher pressure zones around the roof and body, thereby generating downforce, increasing the friction between the vehicle tires and the ground, and improving the stability of the vehicle.

[0032] like Figure 2 As shown, the second mounting plate 3 is connected to symmetrically distributed protrusions 11, and the second mounting plate 3 and the two protrusions 11 are integrally formed.

[0033] like Figure 1 As shown, the second mounting plate 3 has symmetrically distributed first mounting holes 12 and several second mounting holes 13, with the several second mounting holes 13 located between two first mounting holes 12.

[0034] like Figure 1 and Figure 2 As shown, a connecting block 14 is provided at one end of the upper surface of the main body 1 of the decorative panel. A decorative light 15 is installed inside the connecting block 14. The connecting block 14 is located in the middle of the main body 1 of the decorative panel, and the connecting block 14 and the main body 1 of the decorative panel are integrally formed.

[0035] like Figure 1 As shown, the two fourth connecting strips 9 are located between the two third connecting strips 8. The two first locking pins 4 cooperate with the two third connecting strips 8 and the fourth connecting strips 9 to facilitate the installation and fixation of the two first mounting plates 2.

[0036] like Figure 1 and Figure 4 As shown, multiple connectors 16 are connected to the main body of the decorative panel 1.

[0037] Specifically, when using the lower trim panel of this car's rear spoiler: Two first locking pins 4, in conjunction with two third connecting strips 8 and a fourth connecting strip 9, facilitate the installation and fixation of the two first mounting plates 2; two second locking pins 5, in conjunction with two first connecting strips 6 and a second connecting strip 7, facilitate the installation and fixation of the trim panel body 1; and a fifth connecting strip 10, in conjunction with the first mounting hole 12 and the second mounting hole 13, facilitates the installation and fixation of the second mounting plate 3. Because the lower surface of the trim panel body 1 is a curved surface, during vehicle operation, when airflow passes under the car, the curved lower surface can guide the airflow more smoothly, as the curve allows the air to pass more evenly. The sliding surface flows along the curved surface, reducing airflow separation and turbulence, and optimizing airflow direction. At the same time, the curved lower surface increases the airflow speed through the main body of the trim panel, creating a relatively low pressure zone under the car. This creates a pressure difference with the higher pressure zones around the roof and body, generating downforce and increasing the friction between the vehicle tires and the ground, thus improving vehicle stability. During driving, foreign objects such as stones and mud on the road may be kicked up by the wheels and impact the undercarriage components. The curved lower surface can disperse the impact force of foreign objects to a certain extent. When a foreign object impacts, due to the characteristics of the curved surface, the impact force will be dispersed along the curved surface rather than concentrated at a single point.

[0038] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the utility model, are covered within the scope of the claims of the present utility model.
