Description

Technical Field

[0001] This utility model belongs to the field of active tail fin technology, and specifically relates to an improved active tail fin structure. Background Technology

[0002] Active rear wings are typically found on the rear of sports sedans and sports cars, primarily to reduce lift at the rear of the vehicle. If the lift at the rear is greater than that at the front, it can easily lead to oversteer, reduced rear wheel grip, and decreased high-speed stability. This requires the active rear wing to provide stable downforce during driving, necessitating high rigidity and, in terms of fuel efficiency, as low weight as possible. Aesthetically pleasing designs are also important. Existing active rear wings mainly use sheet metal stamping parts, formed by bending and wrapping inner and outer panels. This bending of the outer sheet metal to wrap the inner sheet metal results in bends and notches at corners, leading to an unattractive appearance. Furthermore, because they are made of sheet metal, they are relatively heavy. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide an improved active tail wing structure that improves the overall rigidity of the product, enhances its aesthetics, and reduces weight and wind resistance, in light of the existing technology.

[0004] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: an improved active tail fin structure, characterized in that it includes an active tail fin upper plate and an active tail fin lower plate formed by injection molding, the active tail fin upper plate and the active tail fin lower plate are installed and connected, the active tail fin upper plate and the active tail fin lower plate are installed with an inner cavity, and a reinforcing bracket for enhancing rigidity is provided in the inner cavity.

[0005] In the above-mentioned improved active tail fin structure, the lower active tail fin plate has connecting side arms on both the left and right sides. The connecting side arms are folded towards the upper active tail fin plate. There are glue grooves on the connecting side arms, and structural glue is contained in the glue grooves. The upper active tail fin plate and the lower active tail fin plate are connected together by structural glue.

[0006] In the aforementioned improved active tail fin structure, the lower plate and upper plate of the active tail fin have bent groove areas, and the reinforcing bracket is supported inside the bent groove areas.

[0007] In the aforementioned improved active tail fin structure, the outer surfaces of the upper and lower active tail fin plates have a high-gloss black coating.

[0008] In the aforementioned improved active tail fin structure, the lower part of the active tail fin lower plate is further provided with an insert bracket and a mounting bracket. The insert bracket is embedded and installed with the active tail fin lower plate, and is connected to the external drive component through the mounting bracket.

[0009] Compared with the existing technology, the advantages of this utility model are that the whole is made of injection molded parts and connected by structural adhesive, which effectively reduces the weight of the product and achieves lightweighting. At the same time, the upper and lower plates of the active tail fin are painted with high gloss black, which gives it a high appearance quality. The product assembly structure is all inside, which is conducive to the freedom of appearance design and makes it easier to meet the requirements of reducing wind resistance. While thinning the product, it also enhances the overall rigidity, improves the product's aesthetics, and reduces wind resistance. Attached Figure Description

[0014] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0015] In the figure, the upper active tail fin plate 100; the lower active tail fin plate 200; the connecting side arm 201; the inner cavity 300; the reinforcing bracket 400; the structural adhesive 500; the insert bracket 600; and the mounting bracket 700.

[0016] like Figure 1 and Figure 2 As shown, this improved active rear wing structure includes an injection-molded upper active rear wing plate 100 and an lower active rear wing plate 200. This is to achieve lightweighting, reduce weight, and decrease wind resistance. The outer surfaces of the upper and lower active rear wing plates 100 and 200 have a high-gloss black coating, thus controlling the appearance of both plates and significantly improving the product's aesthetic quality. The upper and lower active rear wing plates 100 and 200 are connected and fitted with an internal cavity 300. Furthermore, during driving, when the active rear wing is in the deployed state, the upper side experiences wind pressure, which can make the vehicle more stable. However, if the lower side protrudes, it will generate wind resistance. Therefore, to reduce wind resistance, the product's cross-sectional thickness should be as thin as possible. However, a thin product will introduce rigidity issues. Figure 4As shown, a reinforcing bracket 400 for enhancing rigidity is provided inside the cavity 300 of this patent. The lower plate of the active tail fin and the upper plate of the active tail fin 100 have bending groove areas. The reinforcing bracket 400 is supported inside the bending groove areas. Since the rigidity is weakest at the bending groove areas, the local rigidity is enhanced by the reinforcing bracket 400 to ensure strength.

[0017] like Figure 3 As shown, the lower active tail fin has connecting side arms 201 on both sides. The connecting side arms 201 are folded towards the upper active tail fin 100. There are glue grooves on the connecting side arms 201, and structural adhesive 500 is contained in the glue grooves. The upper active tail fin 100 and the lower active tail fin are connected together by the structural adhesive 500. Here, the structural adhesive 500 is equivalent to internal assembly and connection, which facilitates the freedom of appearance and makes it easier to achieve the appearance to reduce wind resistance. In addition, the lower part of the lower active tail fin is also provided with an insert bracket 600 and a mounting bracket 700. The insert bracket 600 is embedded and installed in the lower active tail fin, and is connected to the external drive component through the mounting bracket 700. Since the insert bracket 600 is fixedly connected to the lower active tail fin and then connected through the mounting bracket 700, the external drive component can drive the entire active tail fin to work.

[0018] The specific embodiments described herein are merely illustrative examples of the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications to the described specific embodiments or adopt similar methods to replace them, but without departing from the scope defined by the spirit of this utility model.
