[0002] The wind noise of a vehicle is an aerodynamic noise caused by the rapid flow of air, collision, friction and swirl of the vehicle body when the vehicle is driving. The faster the car goes, the louder the noise it produces. Especially for sports cars, the wind noise is relatively loud. The vehicle air intake system (the collection of parts that introduce air or mixed gas into the engine cylinder is the engine air intake system) provides clean, dry and sufficient air for the engine. The main components of the vehicle air intake system are the air intake pipe, air filter and air outlet pipe. In the prior art, the number of air inlets and air outlets of the air intake pipe is consistent, and generally only one is provided. However, the air intake efficiency of the air intake pipe is low, and the wind noise of the vehicle is relatively large. Utility Model Content

[0003] The utility model aims to at least solve the technical problems existing in the prior art that the number of air inlets and air outlets of the air intake pipe is kept consistent, and generally only one air inlet is provided, but the air intake efficiency of the air intake pipe is low and the wind noise of the vehicle is relatively large.

[0026] Various aspects and features of the present invention are described herein with reference to the accompanying drawings.

[0027] It should be understood that various modifications may be made to the embodiments of the present application. Therefore, the above description should not be considered as limiting, but only as an example of the embodiments. Other modifications within the scope and spirit of the present utility model will occur to those skilled in the art.

[0028] The accompanying drawings, which are included in and constitute a part of the specification, illustrate embodiments of the present invention and, together with the general description of the present invention given above and the detailed description of the embodiments given below, are used to explain the principles of the present invention.

[0029] These and other characteristics of the invention will become apparent from the following description of a preferred form of embodiment given as a non-limiting example, with reference to the accompanying drawings.

[0030] It should also be understood that although the present invention has been described with reference to some specific examples, those skilled in the art will be able to realize many other equivalent forms of the present invention that have the features described in the claims and are therefore within the scope of protection defined thereby.

[0031] The above and other aspects, features and advantages of the present invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

[0032] Specific embodiments of the present invention are described hereinafter with reference to the accompanying drawings; however, it should be understood that the embodiments applied for are merely examples of the present invention, which may be implemented in a variety of ways. Well-known and / or repeated functions and structures are not described in detail to avoid unnecessary or redundant details that obscure the present invention. Therefore, the specific structural and functional details applied for herein are not intended to be limiting, but merely serve as the basis and representative basis for the claims to teach those skilled in the art to use the present invention in a variety of ways with substantially any suitable detailed structure.

[0033] The first embodiment of the utility model provides an air intake structure, such as Figure 1-6 As shown, the air intake structure is installed on the top of the vehicle, and includes an air intake pipe 1 and an air outlet pipe 2 that are interconnected. The air intake pipe 1 has an air inlet 11, and the air outlet pipe 2 has an air outlet 21. The air intake pipe 1 is suspended above the vehicle roof 100, and the air intake 11 faces the front of the vehicle. There are multiple air outlets 21, and each air outlet 21 is respectively connected to an air filter.

[0034] Since the wind resistance at the top of the vehicle is small and the air flow speed is fast, arranging the air intake structure at the top of the vehicle is conducive to external air entering the air filter along the air intake structure, thereby improving the air intake efficiency; Figure 1 and Figure 2 As shown, the air intake structure includes an air intake pipe 1 and an air outlet pipe 2. The air intake pipe 1 has an air intake port 11, and the air outlet pipe 2 has an air outlet 21. External air enters the air intake pipe 1 along the air intake port 11, and enters the air filter through the air outlet pipe 2 and the air outlet 21. The air intake pipe 1 is suspended above the vehicle roof 100, which is conducive to high-speed airflow entering the air intake pipe 1 through the air intake port 11, while low-speed airflow does not enter the air intake pipe 1; there are multiple air outlets 21, and the gas entering the air intake pipe 1 from the air intake port 11 can enter the air filter through multiple air outlets 21 respectively, dividing the airflow in the air intake pipe 1 into multiple airflows and guiding them into the air filter, further improving the air intake efficiency entering the air filter, and reducing wind noise at the same time.

[0035] The airflow close to the top of the vehicle cover 100 is a low-speed airflow, and the airflow above the vehicle cover 100 is a high-speed airflow. As much high-speed airflow as possible enters the air filter, which is conducive to providing sufficient air for the engine. Specifically, there is a gap 3 between the intake pipe 1 and the vehicle cover 100, so that the intake pipe 1 is suspended above the vehicle cover 100, and one end of the intake pipe 1 forms a suspended air inlet 11 to prevent the low-speed airflow in the boundary layer on the surface of the vehicle cover 100 from entering the intake pipe 1. Only high-speed airflow enters, thereby ensuring the intake efficiency of the intake structure.

[0036] In some embodiments, the air outlet pipe 2 is arranged on the inner side of the vehicle roof 100, and the air outlet pipe 2 includes an air distribution pipe 22 and a plurality of branch pipes 23. One end of the air distribution pipe 22 is connected to the air inlet pipe 1, and the other end of the air distribution pipe 22 is connected to one end of each branch pipe 23. The other end of each branch pipe 23 has an air outlet 21. Among them, the air outlet pipe 2 is arranged on the inner side of the vehicle roof 100, that is, arranged inside the vehicle, which reduces the space occupied by the air intake structure outside the vehicle and can reduce wind resistance at the same time. The air outlet pipe 2 is set as an air distribution pipe 22 and a plurality of branch pipes 23. The air distribution pipe 22 is used to connect with the air inlet pipe 1, and the branch pipe 23 is provided with a plurality of branches, which divide the airflow entering the air distribution pipe 22 from the air inlet pipe 1 into multiple airflows entering the air filter. The same volume of airflow entering the air filter takes less time, thereby improving the air intake efficiency of the air filter.

[0037] In some embodiments, the air inlet 11 is arranged in the transverse middle position of the vehicle roof 100, and the air outlets 21 are symmetrically arranged on both transverse sides of the air inlet 11. The air inlet 11 faces the direction of the vehicle's forward movement, and the airflow enters the air intake pipe 1 from the air inlet 11 more easily during the vehicle's driving. The transverse direction of the air intake pipe 1 roof refers to the width direction of the vehicle. The air inlet 1 is arranged in the transverse middle position of the vehicle roof 100, and the air outlets 21 are symmetrically arranged on both transverse sides of the air inlet 11 to ensure uniform air intake at all positions of the air intake structure. Exemplarily, there is one air inlet 11, two air outlets 21, and one air outlet 21 is arranged on each transverse side of the air inlet 11.

[0038] In order to improve the appearance of the portion of the air intake structure exposed outside the vehicle, an air intake decorative cover 4 is provided on the periphery of the air intake pipe 1. At the same time, the air intake decorative cover 4 can also improve the structural strength of the air intake pipe 1. Figure 3 As shown, the two ends of the air intake pipe 1 and the two ends of the air intake decorative cover 4 are sealed and connected by structural adhesive 5, so as to improve the connection strength and sealing performance of the air intake pipe 1 and the air intake decorative cover 4. Specifically, the end of the air intake pipe 1 close to the vehicle roof 100 has a first connection flange extending around along the edge of the air intake pipe 1, and the air intake decorative cover 4 has a second connection flange extending along the length direction of the vehicle roof 100. The first connection flange and the second connection flange are connected at the vehicle roof 100 by sealant.

[0039] In some embodiments, the air intake pipe 1 and the air intake decorative cover 4 are streamlined, respectively. The streamlined design of the air intake pipe 1 and the air intake decorative cover 4 has low wind resistance, which effectively reduces the impact of wind resistance on the vehicle.

[0040] In some embodiments, the air intake pipe 1 and the air intake decorative cover 4 are carbon fiber structures. The carbon fiber structure is conducive to achieving lightweight air intake structure, and the air intake pipe 1 and the air intake decorative cover 4 are carbon fiber structures, which is conducive to realizing the air intake pipe 1 and the air intake decorative cover 4 to be formed by autoclave process, and then the air intake pipe 1 and the air intake decorative cover 4 are processed into a streamlined structure.

[0041] In some embodiments, Figure 4 As shown, the air intake pipe 1 is connected to the vehicle roof 100 through a plurality of fasteners 7, and the plurality of fasteners 7 are distributed in a triangular shape. Exemplarily, the fasteners 7 are fastening bolts, which are arranged at a plurality of positions on the vehicle roof 100, providing a plurality of installation points for the installation of the air intake pipe 1, and the plurality of fasteners 7 are distributed in a triangular shape, ensuring the installation stability of the air intake pipe 1 and the vehicle roof 100. Exemplarily, three fasteners are provided, and the three fasteners are distributed in a triangular shape.

[0042] In some embodiments, Figure 5 and Figure 6 As shown, the vehicle roof 100 is provided with a vent 101 which is connected with the air inlet pipe 1 and the air outlet pipe 2 respectively. Specifically, the vent 101 is used to connect the air inlet pipe 1 and the air outlet pipe 2 to ensure that the air flow continuously flows in the air inlet pipe 1 and the air outlet pipe 2. Since the vent 101 is provided on the vehicle roof 100, the sealing performance between the vehicle roof 100 and the air inlet pipe 1 and the air outlet pipe 2 will be affected. In order to compensate for the sealing performance loss caused by the vent 101, sealing members 6 are respectively provided at the upper and lower sides of the vehicle roof 100 near the vent 101. The air inlet pipe 1 on the upper side of the vehicle roof 100 forms a sealed air duct with the air outlet pipe 2 on the lower side of the engine cover through the vent 101, which can improve the sealing performance between the vehicle roof 100 and the air inlet pipe 1 and the air outlet pipe 2.

[0043] Exemplarily, the sealing member 6 is a sponge gasket surrounding the vent 101. The sealing member 6 is set as a sponge gasket to improve the sealing performance between the vehicle roof 100 and the air inlet pipe 1 and the air outlet pipe 2, and can also play a buffering role to prevent the air inlet pipe 1 and the air outlet pipe 2 from scratching the vehicle roof 100, and to prevent the air inlet pipe 1 and the air outlet pipe 2 from directly contacting the vehicle roof 100 and generating abnormal noise.

[0044] In some embodiments, the air intake structure is installed on the top of the vehicle tailgate. Specifically, the air intake pipe 1 is arranged on the outside of the vehicle tailgate, and one end of the air intake pipe 1 has an air intake port 11, which is arranged in the lateral middle position of the vehicle tailgate; the air outlet pipe 2 is arranged on the inside of the vehicle tailgate, and one end of the air outlet pipe 2 is provided with a plurality of air outlets 21, which are symmetrically arranged on both sides of the lateral direction of the air intake port 11, and a vent 101 is provided on the vehicle tailgate. For vehicles with higher driving speeds (such as sports cars), the air intake structure is installed on the top of the vehicle tailgate, and a plurality of air outlets 21 are provided, and the plurality of air outlets are respectively connected to the air filter, so as to improve the air intake efficiency of the air intake structure to the air filter; the air intake pipe 1 is suspended on the upper side of the vehicle tailgate, and a plurality of air outlets 21 are provided, which is conducive to reducing wind noise and wind resistance.
