Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts, in particular to a spoiler assembly with low wind resistance and low energy consumption. Background Art

[0002] A car spoiler, also known as a rear wing, is typically installed on top of the rear of a car. It comes in a variety of shapes, including ducktails and large wings. How it works: When a car is traveling at high speeds, air flows rapidly over the car body. A spoiler can modify the airflow at the rear of the car. For example, it can reduce lift at the rear of the vehicle. Excessive lift at the rear of the vehicle can lead to reduced grip and driving stability. Through proper design, a spoiler creates downforce at the rear of the car, improving stability and handling at high speeds. It also reduces wind resistance to a certain extent. While it inherently generates a certain amount of air resistance, optimized design can guide airflow, making it smoother around the entire vehicle body and thus reducing the vehicle's overall drag coefficient.

[0003] As an example of prior art, see patent document CN209634588U, which discloses a two-color, split-type automobile spoiler, comprising an upper spoiler body and a lower spoiler body. The front end of the upper spoiler body is welded to the front end of the lower spoiler body via a welding boss, and the rear end of the upper spoiler body is welded to the rear end of the lower spoiler body via a loop of induced welding wire. The lower spoiler body is uniformly distributed with a plurality of bolt holes and snap holes, and the lower spoiler body can be fixed to the tailgate sheet metal of the automobile by installing bolts and snaps in these bolt holes and snaps. The purpose of this utility model is to provide a two-color, split-type automobile spoiler with enhanced structural reliability. In this example, the spoiler body mainly comprises an upper spoiler body and a lower spoiler body, and its side wings are directly molded into the spoiler body by integral injection molding. During actual production and use, there are certain defects, such as: 1. It will make the mold of the upper body of the spoiler more complicated, greatly increase the cost of production and manufacturing, and also lead to a higher defective rate; 2. The shape of the side wing is too simple. Since it is integrally formed with the main body of the spoiler, the shape of the side wing cannot be changed; 3. The side wing is a very important part of the spoiler structure that plays a spoiler role. It will cut the air and bear very large air pressure. However, the side wing part in the example does not have a reinforced connection structure between the main body of the spoiler and the lower body of the spoiler. This will make the side wing part more prone to deformation, resulting in unstable spoiler effect. Summary of the Invention

[0045] Example 1

[0046] Reference Figures 1 to 6 A low-drag, low-energy spoiler assembly includes: an inner spoiler frame plate 1, mounted on a tailgate sheet metal 2; an outer spoiler decorative plate 3, mounted on the inner spoiler frame plate 1; downwardly curved deflector wings 4, mounted on either side of the outer spoiler decorative plate 3; and a sealing strip 5, mounted between the outer spoiler decorative plate 3 and the inner spoiler frame plate 1. The assembly also preferably includes a plurality of foam seals 51 of varying shapes, also positioned between the outer spoiler decorative plate 3 and the inner spoiler frame plate 1. The sealing strip 5 and the foam seals 51 work together to provide an excellent sealing function.

[0047] The assembly structure between the guide wing 4, the spoiler outer decorative plate 3, and the spoiler inner frame plate 1 is as follows:

[0048] 1. Pre-positioning connection structure: The guide wing 4 has a first positioning dowel 41 and a second positioning dowel 42. The first positioning holes 11 are provided on both sides of the spoiler inner frame plate 1, and the second positioning holes 31 are provided on both sides of the spoiler outer decorative plate 3. The first positioning dowel 41 is inserted into the first positioning hole 11, and the second positioning dowel 42 is inserted into the second positioning hole 31, so that the guide wing 4 forms a plug-in fit with the spoiler inner frame plate 1 and the spoiler outer decorative plate 3 respectively.

[0049] 2. Fixed connection structure: The rear end of the outer decorative panel 3 of the spoiler is provided with a fixed connection part 32 downward, and a plurality of vertical positioning grooves 321 are opened on the fixed connection part 32, and a plurality of positioning protrusions 12 are provided on the rear end of the inner frame plate 1 of the spoiler, and the positioning protrusions 12 are inserted into the vertical positioning grooves 321; the fixed connection part 32 and the inner frame plate 1 of the spoiler are provided with relatively positioned fixing holes 322, and a first fastener (such as a screw, etc., not shown in the figure) is inserted into the fixing hole 322 to fix the outer decorative panel 3 of the spoiler to the inner frame plate 1 of the spoiler.

[0050] During the installation process, the guide side wing 4 is first quickly positioned and connected to the spoiler outer decorative panel 3 and the spoiler inner frame panel 1 through the pre-positioning connection structure, and the spoiler outer decorative panel 3 is then completely fixed to the spoiler inner frame panel 1 through the fixed connection structure. The two methods work together to achieve the effect of fast assembly and high connection strength after assembly.

[0051] The above is the basic structural scheme of the present invention. It differs from the prior art in that the deflector flaps 4, the outer spoiler decorative panel 3, and the inner spoiler frame panel 1 are all separately manufactured and formed components, which are subsequently assembled into a complete spoiler assembly through pre-positioned connection structures and fixed joint structures. The advantages of the present invention include: first, each component is individually formed, which simplifies the components themselves and the molding molds, thereby reducing manufacturing costs and improving product qualification rates; second, the flaps are interchangeable; flaps of different shapes only need to have the same pre-positioned connection structures and can be assembled to the outer spoiler decorative panel 3 and the inner spoiler frame panel 1, thus forming a modular design, making the spoiler assembly more diverse and meeting the needs of different vehicles; third, the pre-positioned connection structures between the deflector flaps 4 and the outer spoiler decorative panel 3 and the inner spoiler frame panel 1 provide higher connection strength and better structural stability. Even when subjected to high air pressure, the deflector flaps 4 can still be prevented from deforming, providing a long-term and stable spoiler effect.

[0052] In order to further enhance the positioning effect during the pre-assembly process, the preferred structural scheme adopted is: Figures 7 and 8 The lower end of the spoiler inner frame plate 1 is provided with a plurality of locating pins 13 protruding therefrom. The tailgate sheet metal 2 is provided with pin holes 21 adapted to the locating pins 13. The locating pins 13 can be inserted into the pin holes 21 to position and assemble the spoiler inner frame plate 1 to the tailgate sheet metal 2. More specifically, a sealing gasket 52 is also included. The lower end of the spoiler inner frame plate 1 has a downwardly protruding pressing portion 14. The locating pins 13 are formed on the pressing portion 14. The sealing gasket 52 has a through hole 521. The locating pins 13 pass through the through hole 521 to press the sealing gasket 52 tightly between the spoiler inner frame plate 1 and the tailgate sheet metal 2 via the pressing portion 14, thereby filling the structural gap, making the fit tighter, and effectively sealing, shock absorbing, and absorbing energy.

[0053] Reference Figure 3 Optionally, the vertical positioning groove 321 has a lower end opening 3211, and the vertical positioning groove 321 is at least gradually narrowed from the bottom. The positioning protrusion 12 is inserted into the vertical positioning groove 321 from bottom to top, and the positioning protrusion 12 forms an interference fit with the inner wall of the vertical positioning groove 321, so that the positioning protrusion 12 and the vertical positioning groove 321 are tightly matched and not easy to loosen, which facilitates the subsequent assembly of the first fastener.

[0054] Example 2

[0055] Based on the structure of the first embodiment, this embodiment provides more preferred installation structures for the spoiler inner frame plate 1 and the spoiler outer decorative plate 3. Figures 7 to 10 , as follows:

[0056] 1. It also includes a waterproof buckle 6. A buckle mounting hole 15 is opened on the inner frame plate 1 of the spoiler. The waterproof buckle 6 is embedded in the buckle mounting hole 15, and the defensive buckle is inserted into the tailgate sheet metal 2 to pre-assemble the inner frame plate 1 of the spoiler to the tailgate sheet metal 2 to realize the connection function.

[0057] Furthermore, the lower end of the inner spoiler frame plate 1 has a downwardly projecting relief portion 151. The snap-fit ​​mounting hole 15 is formed in the relief portion 151. A relief space 152 is defined between the relief portion 151 and the outer spoiler decorative panel 3. The provision of relief space 152 provides clearance after installation, eliminating structural interference between components. This allows the outer spoiler decorative panel 3 to attach to the inner spoiler frame plate 1 in a straight and flat manner, resulting in a smooth and unobtrusive structure. This provides a better spoiler effect, reduces air resistance, and forms a low-drag, low-energy spoiler assembly.

[0058] Preferably, the waterproof buckle 6 has an axial section 61, an H-shaped fitting section 62 and a deformable suction cup section 63; the axial section 61 is at least partially located in the avoidance space 152 and does not contact the spoiler outer decorative panel 3, eliminating structural interference; the H-shaped fitting section 62 is embedded in the buckle mounting hole 15, and the H-shaped fitting section 62 is tightly attached to the inner and outer walls of the spoiler inner frame plate 1; the deformable suction cup section 63 is formed by the edge of the H-shaped fitting section 62 extending outward, and the deformable suction cup section 63 is located between the spoiler inner frame plate 1 and the tailgate sheet metal 2, and forms a vacuum negative pressure space 631 between the spoiler inner frame plate 1 and the tailgate sheet metal 2. With the uneven surface of the tailgate sheet metal 2, the deformable suction cup section 63 can adaptively deform after being subjected to force, so as to always ensure contact with the tailgate sheet metal 2 and form a vacuum negative pressure space 631, which plays a role in spatial isolation, blocks the buckle mounting hole 15, and has an effective water release effect.

[0059] Second, the spoiler inner frame plate 1 also includes an H-shaped nut 7. The spoiler inner frame plate 1 is provided with a nut mounting hole 16. The H-shaped nut 7 is inserted into the nut mounting hole 16 and aligned with the bolt mounting hole on the tailgate sheet metal 2. A second fastener (such as a bolt, not shown) is inserted through the bolt mounting hole and then inserted into the H-shaped nut 7 to secure the spoiler inner frame plate 1 to the tailgate sheet metal 2. Preferably, a hard bolt washer 161 is also included. The H-shaped nut 7 is made of soft rubber and is positioned between the H-shaped nut 7 and the tailgate sheet metal 2. The provision of bolt washer 161 improves the assembly precision between the second fastener and the H-shaped nut 7, thereby ensuring the stability of the connection structure. The soft rubber H-shaped nut 7 forms an interference fit with the second fastener and the bolt mounting hole, respectively. This, firstly, eliminates gaps and provides a waterproof seal. Secondly, it ensures a tight connection and resists vibration forces, preventing the second fastener from loosening, thereby ensuring the reliability of the connection.

[0060] Example 3

[0061] Reference Figures 11 to 13 In some preferred embodiments of the present invention, a wiring harness cover 8 is also included. The wiring harness cover 8 is assembled to the inner frame plate 1 of the spoiler through a snap-on structure 9, and several wiring harness channels 81 are formed between the wiring harness cover 8 and the inner frame plate 1 of the spoiler. The cables are embedded in the wiring harness channels 81 to realize hidden installation of the circuit structure.

[0062] Furthermore, the buckle structure 9 includes a buckle body 91 formed on the inner side frame plate 1 of the spoiler, and a buckle groove 92 opened on the wiring harness cover 8; wherein, the inner wall of the buckle groove 92 is provided with an anti-slip rib 921, and the end of the buckle body 91 is provided with a hook portion 911, and the hook portion 911 can be abutted against the anti-slip rib 921 and form a limited anti-slip fit to prevent the buckle body 91 from loosening, thereby ensuring the structural stability after assembly; the buckle body 91 also has a structural reinforcement rib 912 to increase the structural strength of the buckle body 91; on the other hand, a deformation area 913 is formed between the reinforcement rib and the hook portion 911. When the wiring harness cover 8 needs to be opened (for example, for cable maintenance), a force is applied to the buckle body 91 with the help of hands or tools. Due to the existence of the deformation area 913, the buckle body 91 can be deformed, thereby separating the anti-slip rib 921 from the hook portion, and the buckle body 91 can be easily disassembled.

[0063] It is worth noting that other technical solutions of the present invention belong to the existing technology and are therefore not described in detail.

[0064] The above is only a preferred embodiment of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the concept of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
