The car cover is a common protective product for the outer surface of the automobile, which is mainly used for preventing the car paint from being scratched, faded and damaged by other external factors. However, the traditional car cover has a single function, which only focuses on the physical protection of the car paint.
[0003] In the prior art, the car cover is often coated with a low friction coefficient material such as polytetrafluoroethylene coating. Such smooth surface can promote the air to slide on the surface more easily, like ice surface facilitating the sliding of objects, thereby reducing the air resistance to a certain extent. However, when the air slides on the smooth surface, the airflow is easily disturbed. This disturbance will partially offset the effect of reducing resistance, especially when the vehicle is running at high speed, the disturbed airflow not only produces additional resistance, but also causes noise. This makes it difficult for the vehicle to reduce the wind resistance effectively by simply relying on the smooth surface, resulting in poor fuel efficiency improvement effect of the vehicle, and limiting the optimization degree of the range of the electric vehicle. In addition, in order to achieve more significant wind resistance reduction effect, it is often necessary to separately set a flow guide plate and other components, which undoubtedly increases the production cost. Whether it is the procurement, manufacturing and processing of the flow guide plate, or the installation and debugging, it will greatly increase the overall cost, and bring economic pressure and cost control to the production and subsequent use of the vehicle.

[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.
[0025] Please refer to Figures 1-7 The utility model provides a technical scheme:
[0026] Please refer to Figures 1-7 As shown in the figure, a car cover with air flow guiding function, including car cover body 1, automobile 5, flow guide protrusion 2, the car cover body 1 is integrally formed with multiple flow guide protrusions 2, the flow guide protrusion 2 extends to S shape from the direction of car head to tail, the first flow guide groove 3 is formed between two adjacent flow guide protrusions 2, the height of flow guide protrusion 2 is set to 5MM; The first flow guide groove 3 is S-shaped, and the number is set to two, two first flow guide grooves 3 are symmetrically arranged, and the extension direction of the first flow guide groove 3 is extended from the middle to the side direction close to the car window; Side flow guide groove 10, which is provided on the car cover body 1 close to the door, is S-shaped.
[0027] When the car 5 is running, the flow guide protrusions 2 on the car cover body 1 extend in an S shape from the front to the rear of the car, and these flow guide protrusions 2 first contact the airflow. Due to the unique S-shaped design, they can guide the oncoming airflow more finely and orderly. When the airflow flows along the S-shaped surface of the flow guide protrusions 2, it is gradually changed in flow direction and speed. Part of the airflow is shunted to both sides of the car body along the trend of the flow guide protrusions 2, reducing the direct impact of the airflow on the front of the car, thereby reducing the wind resistance of the vehicle running.
[0028] The first flow guide grooves 3 formed between adjacent flow guide protrusions 2 are also S-shaped and symmetrical, and there are two of them. The extension direction extends from the middle to the side direction close to the window. The first flow guide grooves 3 serve to further arrange and optimize the airflow that has been preliminarily shunted by the flow guide protrusions 2. When the airflow enters the first flow guide grooves 3, it continues to flow in an S-shaped path in the grooves, enabling the airflow in the middle region of the car body to flow more smoothly and orderly to the side of the window, avoiding turbulence or vortex in the middle region of the car body, further reducing wind resistance, and reducing noise caused by turbulence.
[0029] The S-shaped structure of the side flow guide grooves 10 of the car cover body 1 near the doors can effectively guide the airflow on the side of the car body. When the vehicle is running, the airflow on the side of the car body will enter the side flow guide grooves 10. The airflow flowing along the S-shaped side flow guide grooves 10 can better adhere to the side of the car body, reducing the negative pressure area formed by the airflow separating from the side of the car body, thereby reducing wind resistance and enhancing the stability of the vehicle during running.
[0030] Through the coordinated operation of the flow guide protrusions 2, the first flow guide grooves 3 and the side flow guide grooves 10 carefully designed on the car cover body 1, the airflow around the car body during the running of the car 5 can be extremely effectively guided and combed. Compared with the traditional way of separately installing flow guide plates 7, the car cover combines the flow guide structure with the car cover, achieving aesthetics while significantly reducing costs. These structures also have excellent auxiliary flow guiding effect. They reduce the disordered impact and interference of the airflow on the car body, effectively reduce the running resistance of the vehicle, and thus improve the fuel economy. At the same time, due to the great improvement in airflow turbulence, the noise generated is also significantly reduced, which undoubtedly improves the comfort and quietness of driving. Furthermore, thanks to the reasonable distribution and guidance of the airflow, the car cover and the car body can always maintain close adhesion, effectively reducing the situation of local lifting or wear of the car cover caused by airflow impact, thereby prolonging the service life of the car cover and providing all-round optimization and protection for the vehicle.
[0031] It should be noted that, in general, the height of the flow guide protrusion 2 can be about 5mm, which can more effectively guide the high-speed airflow, reduce the air resistance of the vehicle, and enhance the stability of the vehicle driving.
[0032] Referring to Figures 5-6 , the cross section of the flow guide protrusion 2 is triangular, and the top of the flow guide protrusion 2 is provided with a rounded corner.
[0033] The cross section of the flow guide protrusion 2 is triangular, which has good air flow guiding effect in aerodynamics. When the vehicle is driving, the airflow encounters the flow guide protrusion 2, and the inclined edge of the triangular shape can guide the airflow to flow to both sides along the inclined edge. Compared with other shapes, it can more effectively change the direction of the airflow, so that the airflow flows more smoothly along the surface of the vehicle body, thereby reducing the wind resistance during driving of the vehicle. For example, compared with the protrusion with square cross section, the protrusion with triangular cross section will not cause sharp turning and collision of the airflow, reducing the degree of turbulence of the airflow.
[0034] The top of the flow guide protrusion 2 is provided with a rounded corner, which further optimizes the air flow guiding effect. The rounded corner can reduce the separation phenomenon of the airflow when passing through the top of the protrusion. If the top is a sharp corner, the airflow is easy to separate when passing through, forming a vortex and increasing the wind resistance. The rounded corner allows the airflow to flow more smoothly over the top of the protrusion, avoiding the formation of vortex, further reducing the wind resistance and improving the fuel economy of the vehicle.
[0035] Referring to Figure 5 , the triangular rib 6 is fixedly installed at one end of the flow guide protrusion 2 close to the vehicle head.
[0036] When the vehicle is driving forward, the air first hits the head part. The triangular rib 6 fixedly installed at one end of the flow guide protrusion 2 close to the vehicle head can initially divide the oncoming airflow, and the shape of the triangular rib 6 allows the airflow to be quickly divided into several different directions. A part of the airflow flows upward or to both sides along the inclined edge of the triangular rib 6, providing a more orderly initial state for the airflow that subsequently passes through the flow guide protrusion 2. Compared with the case without the triangular rib 6, it can more effectively guide the airflow to avoid direct impact on the front of the vehicle head, thereby reducing the wind resistance of the vehicle head part.
[0037] Referring to Figures 1-2 , a plurality of flow guide pieces 4 are integrally formed on the vehicle cover body 1, and adjacent two flow guide pieces 4 form a guide groove, and the height of the flow guide piece 4 is 5mm.
[0038] A plurality of guide vanes 4 are fixed on the car cover body 1, and two adjacent guide vanes 4 form a guide groove. When the vehicle is running, the airflow passes through the guide groove, and the guide vane 4 can accurately guide the direction of the airflow. Compared with the case without guide vanes 4, the airflow no longer flows disorderly through the vehicle body, but is limited in the guide groove and flows along the designed path, so that the airflow is more regular and the turbulence degree of the airflow is effectively reduced, thereby reducing the wind resistance.
[0039] Referring to Figures 1-2 , the whole of the guide vane 4 extends from the middle to the side, and the guide vane 4 is inclined, and the guide groove is also inclined.
[0040] The guide vane 4 extends from the middle to the side and is inclined, and the guide groove is also inclined. This design conforms to the natural flow direction of the airflow when the vehicle is running. When the vehicle is running forward, the airflow will have a natural side slip tendency on the side of the vehicle body, and the inclined guide vane 4 and the guide groove can well capture and guide this part of the airflow, so that the airflow flows smoothly from the middle of the vehicle body to the side in an inclined direction. This can effectively reduce the turbulence and vortex of the airflow on the side of the vehicle body, further reducing the wind resistance of the vehicle running.
[0041] Referring to Figures 1-3 , the car cover body 1 is integrally formed with a plurality of guide plates 7 near the bottom of the car head of the automobile 5, and a second guide groove 8 is formed between two adjacent guide plates 7, and the protruding length of the guide plate 7 is 5CM.
[0042] Turbulence is easy to occur at the bottom of the car head, which will increase the running resistance of the vehicle. The existence of the second guide groove 8 can effectively reduce this turbulence phenomenon. The second guide groove 8 formed by two adjacent guide plates 7 provides a specific flow path for the airflow, so that the airflow can flow more smoothly from the bottom of the car head, avoiding the collision and rotation of the airflow at the bottom of the car head to form turbulence, thereby reducing the wind resistance at the bottom of the car head and helping to improve the fuel economy of the vehicle.
[0043] Referring to Figures 2-3 , the tail of the guide plate 7 extends to the side, and the second guide groove 8 is also inclined.
[0044] This can also make the airflow at the bottom of the car head better blend with the airflow on the side of the vehicle body. The airflow on the side of the vehicle body itself has a certain flow direction and speed, and the airflow guided by the inclined second guide groove 8 can converge at a suitable angle. This can optimize the overall airflow distribution of the vehicle body, make the airflow around the vehicle body more uniform and stable, further reduce the wind resistance of the vehicle running, and improve the fuel economy.
[0045] Referring to Figure 7 , a bonding layer 9 is fixedly installed between the car cover body 1 and the automobile 5, and the material of the car cover body 1 is polyurethane or the like.
[0046] The presence of the adhesive layer 9 ensures that the car cover body 1 can be firmly attached to the surface of the car 5. During the driving process of the vehicle, various external forces will be applied, such as the impact force of air, vibration, and slight collision with external objects, etc. The adhesive layer 9 can make the car cover body 1 closely adhere to the car 5, prevent the car cover body 1 from shifting, lifting, and other situations, and ensure that the car cover can continuously play its protective role.
[0047] The polyurethane material has good flexibility and elasticity. During the driving process of the vehicle, when the car cover is subjected to external forces such as stone impact, tree branch scratching, etc., the car cover body 1 made of polyurethane material can absorb the impact force through its elastic deformation, effectively preventing the car paint from being scratched. For example, for some high-speed impact of small stones, the polyurethane car cover can buffer the impact force, avoiding the appearance of dents or scratches on the car paint.
