[0032] In the related art, the luggage rack is mounted on the top of the vehicle body for loading objects. Generally, there is a gap between the luggage rack and the vehicle body. When driving at high speed, air will pass through the gap between the luggage rack and the vehicle body. Since the air is subjected to compression, a sharp noise will be emitted, and the driving resistance will be increased, resulting in a poor driving experience.

[0033] As Figure 1 and Figure 2 shown, to solve the above technical problems, the embodiments of the present application provide a low wind noise high bearing multifunctional expansion roof platform, which comprises a roof frame 200 and a flow guide assembly 100, the roof frame 200 is arranged on the top of the vehicle body; the flow guide assembly 100 comprises a flow guide plate 110 and an inner lining plate 120, the flow guide plate 110 and the inner lining plate 120 are arranged at the front end of the roof frame 200, the flow guide plate 110 is gradually inclined to the rear end of the roof frame 200 from bottom to top, the flow guide plate 110 is arranged as an elastic member, the lower end of the flow guide plate 110 abuts against the top of the vehicle body, the elastic deformation of the flow guide plate 110 makes the lower end of the flow guide plate 110 tightly seal with the top of the vehicle body, and the inner lining plate 120 abuts against one side of the flow guide plate 110 towards the rear end of the roof frame 200.

[0034] In these embodiments, the structure of the low wind noise high bearing multifunctional expansion roof platform is as follows:

[0035] The roof frame 200 is installed on the top of the vehicle. The roof frame 200 serves as a support structure for fixing luggage or other items. Exemplarily, the roof frame 200 can be arranged as a frame structure, or as a hollow structure. Generally, in order to reduce the overall weight, the roof frame 200 is made of aluminum alloy material.

[0036] The flow guide assembly 100 is composed of the flow guide plate 110 and the inner lining plate 120. The flow guide assembly 100 is arranged at the front end of the roof frame 200. Among them, the flow guide plate 110 is gradually inclined to the rear from bottom to top, forming an inclined surface for guiding air flow. It should be noted that the flow guide member is made of elastic material, allowing it to deform to a certain extent. That is, the flow guide plate 110 deforms elastically to ensure that the lower end of the flow guide plate 110 is tightly attached to the top of the vehicle body, eliminating the gap between the flow guide plate 110 and the top of the vehicle body, preventing air from entering and reducing wind noise. And, optimizing the air flow path, reducing air resistance, improving fuel efficiency or the cruising range of electric vehicles. Exemplarily, the flow guide plate 110 is made of vulcanized rubber plate, rubber plate, plastic sheet, etc., which is not limited here.

[0037] The inner lining plate 120 abuts against one side of the flow guide plate 110 towards the rear end of the roof frame 200. The inner lining plate serves to provide additional support for the flow guide plate 110, maintain the position and shape of the flow guide plate 110 stable, and help achieve better sealing effect.

[0038] Exemplarily, the inner lining plate 120 can be made of metal sheet, such as aluminum alloy plate, steel plate, alloy plate, etc. Of course, in order to reduce the weight, the inner lining plate 120 is provided with weight reduction holes distributed thereon.

[0039] Therefore, by ensuring the elastic deformation of the deflector 110, the close fit between the deflector 110 and the vehicle body is achieved, effectively reducing the noise caused by air passing through the gap. Moreover, with the deflection of the deflector 110, the improved aerodynamic design helps to reduce air resistance when the vehicle is running. Obviously, lower noise level and better fuel economy directly improve the user's driving experience.

[0040] Furthermore, it should be noted that, since the deflector 110 is arranged on the front side of the inner lining plate 120, the erosion of the inner lining plate 120 by rainwater is reduced, and the service life of the inner lining plate 120 is improved.

[0041] As shown in Figure 3 In some embodiments, the side of the deflector 110 close to the rear end of the roof rack 200 is a leeward side, and the side of the inner lining plate 120 facing the deflector 110 is a support side, and the leeward side and the support side are fitted.

[0042] In these embodiments, the design of the deflector 110 and the inner lining plate 120 further optimizes the aerodynamic performance and structural stability of the low wind noise high load bearing multifunctional expansion roof platform. Specifically, the leeward side: this is the side of the deflector 110 close to the rear end of the roof rack 200, which is relatively unaffected by direct wind when the vehicle is running. The support side: the side of the inner lining plate 120 facing the deflector 110 provides the necessary support for the deflector 110, ensuring its shape stability and sealing.

[0043] By fitting the leeward side of the deflector 110 and the support side of the inner lining plate 120 closely, the structural integrity of the entire deflector assembly 100 can be improved. This helps to prevent the deflector 110 from deforming or displacing due to airflow impact at high speed. Moreover, the closely fitted surfaces reduce any gaps that can generate turbulence or noise, allowing the airflow to transition more smoothly, thereby reducing air resistance and wind noise. Good fit means better sealing, preventing air from passing through the gap, thereby reducing additional noise caused by airflow.

[0044] For example, in order to ensure good fit between the leeward side and the support side, the deflector 110 can be made of a material with a certain elasticity, such as rubber, TPE (thermoplastic elastomer), silicone, etc. as mentioned before. These materials not only provide the required elastic deformation to adapt to the top profile of different vehicle models, but also ensure durability and sealing over a long period of use.

[0045] As shown in Figure 2 and Figure 3As shown, in some embodiments, the upper ends of the support surface and the leeward surface are attached, the roof rack 200 has an adapter 240 located at the front end of the roof rack 200, the deflector 110 has a deflector connecting portion located between the adapter 240 and the inner lining connecting portion, and the deflector connecting portion, the inner lining connecting portion and the adapter 240 are connected.

[0046] In these embodiments, this design ensures the structural stability and functionality of the entire deflector assembly 100. Among them, the upper ends of the support surface and the leeward surface are attached: it ensures that the deflector 110 and the inner lining plate 120 are tightly attached at the position most susceptible to airflow impact (i.e. the upper end), thereby reducing the opportunity for air to enter, reducing noise and air resistance, and avoiding the inner lining plate 120 interfering with the elastic deformation of the lower end of the deflector 110 and the attachment of the roof.

[0047] The adapter 240 serves as an intermediate part located at the front end of the roof rack 200, and serves to connect the deflector 110 and the inner lining plate 120, ensuring that the three form a stable whole. The deflector connecting portion and the inner lining connecting portion are respectively connected to the adapter 240 at the front end of the roof rack 200, forming a three-point connection structure that enhances the stability and durability of the whole.

[0048] By fixing the deflector 110 and the inner lining plate 120 to the roof rack 200 through the adapter 240, the rigidity and vibration resistance of the entire system are improved. The modular design simplifies the installation process and, if a part is damaged, it can be replaced individually without replacing the entire system.

[0049] For the deflector 110 and the inner lining plate 120, materials with good elasticity and weather resistance can be selected, such as TPE, silicone, etc.; while the adapter 240 can use high-strength engineering plastics or lightweight metals, such as aluminum alloy, to ensure sufficient mechanical strength.

[0050] Exemplarily, mechanical fasteners such as buckles, bolts, etc. can be used to ensure the secure connection between the deflector connecting portion, the inner lining connecting portion and the adapter 240.

[0051] As shown in Figure 1 , Figure 2 and Figure 3 , in some embodiments, the low-wind-noise high-load-bearing multifunctional expanded roof platform further comprises an adjusting portion, the adjusting portion is arranged on the adapter 240, the adjusting portion is respectively connected with the deflector connecting portion and the inner lining connecting portion, and the adjusting portion is used to adjust the height position and the inclination angle of the deflector 110 and the inner lining plate 120 relative to the roof of the vehicle.

[0052] In these embodiments, an adjustment part is introduced, which provides height position and inclination angle adjustability for the low wind noise and high load carrying multifunctional roof platform. This design not only enhances the adaptability and flexibility of the system, but also further optimizes the aerodynamic performance and sealing effect.

[0053] The adjustment part allows users to adjust the height of the deflector plate 110 and the inner lining plate 120 according to different vehicle models or load conditions. It ensures that the deflector plate 110 can closely fit the top of the vehicle body of different shapes and heights, maintaining optimal sealing and aerodynamic performance, and improving the universality of the application. In addition, the adjustment part can also change the inclination angle of the deflector plate 110 relative to the top of the vehicle body. By adjusting the inclination angle, the airflow path can be optimized, air resistance and noise can be reduced, and different driving conditions (such as high-speed driving or off-road driving) can be adapted.

[0054] That is, the adjustment part is located on the adapter 240 at the front end of the roof rack 200, serving as a key component connecting the deflector plate 110, the inner lining plate 120, and the roof rack 200. It ensures that the deflector plate 110 and the inner lining plate 120 can be independently adjusted in height and angle, while maintaining coordination between the two.

[0055] Obviously, it can adapt to the changes in the roof profile of different vehicle models, providing better universality and installation convenience. According to the actual use environment, it can be adjusted flexibly to achieve the best aerodynamic effect and sealing performance. Of course, users can adjust the settings at any time according to their own needs, improving driving comfort and safety.

[0056] For example, threaded rods, knobs, or other mechanical adjustment devices can be used to allow users to conveniently fine-tune. Integrating an electric or hydraulic adjustment system can also be considered to provide a more precise and smooth adjustment experience, especially in high-end vehicles. Ensure that the adjusted position is stable and will not loosen due to vibration or long-term use. Locking devices such as locking screws and buckles can be used.

[0057] As shown in Figure 2 and Figure 3 , in some embodiments, the adjustment part includes a fastening bolt and a fastening nut, the adapter 240 has an adjustment hole 241, the adjustment hole 241 is arranged in parallel with the axial direction and the width direction of the roof rack 200, the deflector connecting part has a deflector mounting hole 113, the inner lining connecting part has an inner lining mounting hole 122, the fastening bolt is sequentially arranged in the adjustment hole 241, the deflector mounting hole 113, and the inner lining mounting hole 122, and the fastening bolt is threadedly connected with the fastening nut to clamp and fix the deflector connecting part, the inner lining connecting part, and the adapter 240; wherein the hole diameter of the adjustment hole 241 is greater than the outer diameter of the fastening bolt.

[0058] In these embodiments, the height position and the inclination angle of the deflector plate 110 and the inner lining plate 120 are adjustable by using fastening bolts and fastening nuts in combination with specific hole arrangement. This design is not only simple in structure, but also reliable and effective. The following is a specific description of this embodiment:

[0059] The fastening bolts and the fastening nuts, as the main fixing and adjusting components, provide the necessary mechanical connection and locking function. The axial direction of the adjusting hole 241 is parallel to the width direction of the roof rack 200, which means that the hole is transversely through. The hole diameter of the adjusting hole 241 is larger than the outer diameter of the fastening bolt, allowing horizontal and vertical movement adjustment within a certain range. The deflector mounting hole 113 is used to match the fastening bolt, allowing the deflector plate 110 to be finely adjusted in height and angle relative to the adapter 240. The inner lining mounting hole 122 is also used to match the fastening bolt, ensuring that the inner lining plate 120 can be adjusted synchronously and maintain a consistent positional relationship with the deflector plate 110. After the fastening bolt passes through the deflector mounting hole 113, the adjusting hole 241 and the inner lining mounting hole 122, the fastening nut is screwed to clamp and fix the three components, forming a stable connection structure.

[0060] Obviously, since the hole diameter of the adjusting hole 241 is larger than the outer diameter of the fastening bolt, the deflector plate 110 and the inner lining plate 120 can be finely adjusted by loosening the nut without disassembling the bolt, and then tightened after adjustment is completed. The combination of the bolt and the nut provides strong fixing force, ensuring that it will not loosen under high-speed driving or in harsh environments. If any part needs to be replaced or adjusted, it can be easily operated by loosening the nut, simplifying the maintenance process.

[0061] Furthermore, the use of standard components such as bolts and nuts reduces manufacturing costs and complexity.

[0062] As shown in FIG. 1 1, Figure 3 In some embodiments, the upper end of the inner lining plate 120 has an inner lining folded edge 121, and the upper end of the deflector plate 110 has a deflector folded edge 111, which is stacked above the inner lining folded edge 121, so that the deflector folded edge 111 and the inner lining folded edge 121 form a lamp holder for installing lighting fixtures.

[0063] In these embodiments, the upper end of the inner lining plate 120 is provided with an inner lining folded edge 121, which increases the structural strength and provides a stable foundation for subsequent components. The upper end of the deflector plate 110 is also provided with a deflector folded edge 111, which is stacked above the inner lining folded edge 121, and the two together form a lamp holder. The lamp holder formed by the deflector folded edge 111 and the inner lining folded edge 121 can be used to install various types of lighting fixtures, such as LED light bars, warning lights, etc., to improve the visibility and safety of the vehicle at night or in bad weather conditions.

[0064] The folding design not only increases the structural strength of the inner lining plate 120 and the deflector plate 110, but also ensures the firmness of the lamp holder. Combining lighting function with aerodynamic design, it saves space while improving overall aesthetics. For the installation of the lamp, a special clamping groove, bolt or quick disassembly clamp can be designed to facilitate user replacement.

[0065] Furthermore, since the deflector folding edge 111 is located above the inner lining folding edge 121, it can shield the inner lining folding edge 121, thereby reducing the corrosion of external rainwater on the inner lining folding edge 121.

[0066] For example, the lamp holder is provided with a plurality of adjusting holes 241 for fixing the lamp. Different types of lamps can be selected by choosing the corresponding adjusting hole 241.

[0067] As shown in Figure 1 and Figure 2 , in some embodiments, the end face of the lower end of the deflector plate 110 is provided with a sticking layer 112, which is used to bond the top of the vehicle body.

[0068] In these embodiments, the deflector plate 110 is provided with a sticking layer 112 at the lower end, which is used to directly bond the top of the vehicle body. Further enhancing the sealing and fixing between the deflector plate 110 and the vehicle body, effectively reducing wind noise and improving aerodynamic performance. The sticking layer 112 is provided on the end face of the lower end of the deflector plate 110, serving as a component connecting the deflector plate 110 and the top of the vehicle body. The sticking layer 112 can be double-sided tape, structural adhesive or other types of adhesive. Through the sticking layer 112, the deflector plate 110 is ensured to be closely attached to the top of the vehicle body, eliminating any small gaps between the two, thereby significantly reducing wind noise. The direct bonding method increases the stability of the installation of the deflector plate 110, reducing the risk of loosening caused by vehicle vibration or airflow impact when driving at high speed.

[0069] The sticking layer 112 can provide a continuous and uniform sealing interface to prevent air from entering and reduce noise. Compared with traditional mechanical fastening methods, bonding can simplify the installation steps, save time and labor. Some adhesives have good filling performance and can adapt to the slight unevenness that may exist on the top of the vehicle body, ensuring good fit.

[0070] As shown in Figure 1 and Figure 2 , in some embodiments, the roof rack 200 includes a pair of side plates 220 and at least one cross beam 210, the pair of side plates 220 are arranged in parallel, and the pair of side plates 220 are connected through the cross beam 210, and the side plate 220 has a plurality of sequentially connected structural segments, in any two adjacent structural segments, the top height of the structural segment close to the front end of the roof rack 200 is lower than the top height of the structural segment away from the front end of the roof rack 200.

[0071] In these embodiments, the roof rack 200 adopts a special structural segment layout to optimize aerodynamic performance and improve structural stability. This design not only helps to reduce wind resistance and noise, but also enhances the overall strength of the roof rack 200.

[0072] A pair of side plates 220 are arranged in parallel as the main support structure of the roof rack 200 and are connected to the top of the vehicle body. The cross beams 210 connect the two side plates 220 to ensure the stability and rigidity of the entire roof rack 200. Each side plate 220 is composed of multiple structural segments that are connected together in a specific way to form a continuous whole. In any two adjacent structural segments, the top height of the structural segment closer to the front end of the roof rack 200 is lower than the top height of the structural segment farther from the front end of the roof rack 200. This design makes the roof rack 200 gradually rise from front to back, helping to guide the smooth transition of air flow and reduce air resistance and wind noise. The cross beams 210 at the front are installed on the side plates 220 using aluminum end caps, which effectively reduces the height of the side plates 220 while ensuring a safe gap with the vehicle body, making the entire design appear lower and more visually striking.

[0073] For example, the side plates 220 and cross beams 210 should be made of high-strength, lightweight materials such as aluminum alloy or high-strength steel to ensure sufficient mechanical strength and durability while reducing weight.

[0074] For example, the cross beams 210 use 6082-T6 high-strength aluminum material with a tensile strength of 295 MPa and a yield strength of 240 MPa. The aluminum material section is thickened to a thickness of 2.5 mm, which is thicker than the conventional aluminum material thickness of 1.5 mm. The load-bearing capacity of a conventional roof rack 200 is generally 50 kg, while this aluminum rod can withstand a force of 75 kg with a maximum displacement of 3.1 mm and a maximum displacement stress of 46 MPa, which is far below the maximum yield strength, demonstrating excellent load-bearing capacity.

[0075] For example, in this embodiment, the number of cross beams 210 is 6.
