Of course, they are merely examples, and the purpose is not to limit the utility model. In addition, the utility model can repeat reference numbers and / or letters in different examples.

In addition, the utility model provides various specific examples of processes and materials, but those of ordinary skill in the art can be aware of the applicability of other processes and / or the use of other materials.

[0031] The wind guide structure 2 according to an embodiment of the first aspect of the utility model is described below with reference to the accompanying drawings.

[0032] like Figures 1 to 7As shown, the wind guide structure 2 according to the embodiment of the first aspect of the utility model is arranged on the inner side of the fender 1 and includes: a wind guide component 21 and a wind guide mechanism 22. The wind guide component 21 is formed with a wind guide channel 23 extending in the front-to-back direction, and the front and rear ends of the wind guide channel 23 are respectively provided with an air inlet 24 and an air outlet 25. Therefore, the airflow in front of the wind guide component 21 can flow into the wind guide channel 23 through the air inlet 24, and then flow from the air outlet 25 to the rear side of the wind guide component 21, thereby reducing the wind resistance of the vehicle at the wind guide component 21, which is conducive to improving the aerodynamic performance of the vehicle.

[0033] It should be noted that, in the description of this article, “inner side” refers to the side close to the center position of the vehicle in the left-right direction, and “outer side” refers to the side close to the outside of the vehicle in the left-right direction.

[0034] Among them, the air guide mechanism 22 includes a driving unit 221 and multiple air guide blades 222 arranged in the air guide channel 23 along the up and down directions. The air guide blades 222 are rotatable relative to the air guide channel 23 and the rotation axis of the air guide blades 222 extends along the left and right directions. The driving unit 221 is used to drive the multiple air guide blades 222 to rotate. That is to say, the driving unit 221 can change the inclination angle of the air guide blade 222 relative to the extension direction of the air guide channel 23 by driving the air guide blade 222 to rotate. For example, the driving unit 221 can drive the air guide blade 222 to rotate to a position roughly parallel to the extension direction of the air guide channel 23. At this time, the air guide blade 222 has little resistance to the airflow passing through the air guide channel 23, so that the airflow in front of the air guide component 21 can quickly flow through the air guide channel 23 to the rear side of the air guide component 21, which is beneficial to improving the aerodynamic performance of the vehicle; the driving unit 221 can also drive the air guide blade 222 to rotate to a position roughly perpendicular to the extension direction of the air guide channel 23. At this time, the air guide blade 222 can block debris such as stones, mud, etc. from moving backward along the air guide channel 23 with the airflow, thereby preventing the debris from scratching the vehicle body structure located at the rear side of the air guide component 21 when being discharged through the air outlet 25.

[0035] Therefore, the angle between the air guide blade 222 and the extension direction of the air guide channel 23 can be adjusted by the driving unit 221 according to the condition of the driving road surface, so as to reduce the wind resistance at the air guide component 21 and prevent the debris on the front side of the air guide component 21 from moving through the air guide channel 23 to the rear side of the air guide channel 23 and scratching the vehicle body structure, thereby improving the aerodynamic performance of the vehicle and reducing the risk of damage to the vehicle body structure.

[0036] According to the wind guide structure 2 of the embodiment of the utility model, the angle between the wind guide blade 222 and the extension direction of the wind guide channel 23 can be adjusted by the driving unit 221 according to the condition of the driving road surface. While reducing the wind resistance at the wind guide component 21, it can prevent the debris on the front side of the wind guide component 21 from moving through the wind guide channel 23 to the rear side of the wind guide channel 23 to scratch the vehicle body structure, thereby improving the aerodynamic performance of the vehicle while reducing the risk of damage to the vehicle body structure.

[0037] In some embodiments, the area of ​​the air inlet 24 is larger than the area of ​​the air outlet 25. Thus, by reducing the area of ​​the air outlet 25, the gas flow rate at the air outlet 25 is increased, so that the gas flow field around the air outlet 25 can be stabilized.

[0038] According to some embodiments of the utility model, in the left-right direction, the width of the air guide blade 222 is the same as the width of the air guide channel 23. That is, the left and right ends of the air guide blade 222 are respectively in contact with the inner wall surfaces of the two sides of the air guide channel 23 opposite to each other in the left-right direction, so as to avoid turbulence of air flow through the gap between the air guide blade 222 and the air guide channel 23 in the left-right direction, so as to improve the air guiding effect of the air guide channel 23. Specifically, the air guide blade 222 is parallel to the left-right direction to ensure the air guiding and blocking effects of the air guide blade 222.

[0039] According to some embodiments of the utility model, in the direction from front to back, the air guide channel 23 extends upwardly at an angle. That is, the rear end of the air guide channel 23 is higher than the front end of the air guide channel 23, that is, the air outlet 25 is higher than the air inlet 24, and the inner bottom wall of the air guide channel 23 can be formed as an inclined surface extending upwardly at an angle from front to back. Therefore, during the driving process of the vehicle, when debris such as stones, mud blocks, etc. enter the air guide channel 23 through the air inlet 24, the inner bottom wall of the air guide channel 23 arranged at an angle can better block the debris from moving backward along the air guide channel 23 with the air flow, thereby preventing the debris from passing through the air guide channel 23 and being discharged through the air outlet 25 and the exhaust port 41, and further preventing the debris from scratching the vehicle body structure on the rear side of the air guide component 21 when being discharged. In addition, the inner bottom wall of the air guide channel 23 extends downwardly at an angle from the back to the front. Therefore, when the debris is not subjected to external forces, such as when the vehicle is parked, the debris can slide downward along the inner bottom wall of the air guide channel 23 under the action of its own weight and be discharged through the air inlet 24, thereby preventing the debris from accumulating in the air guide channel 23 and affecting the air guiding effect.

[0040] According to some embodiments of the utility model, the air guide blades 222 have at least a first position and a second position, wherein in the first position, the air guide blades 222 are perpendicular to the extension direction of the air guide channel 23, and the plurality of air guide blades 222 cut off the air guide channel 23, and in the second position, the air guide blades 222 are parallel to the extension direction of the air guide channel 23. Therefore, when the air guide blades 222 are in the first position, the plurality of air guide blades 222 can work together to completely close the air guide channel 23, thereby preventing debris from passing through the air guide channel 23 and being discharged from the air outlet 25, and further preventing the debris from scratching the vehicle body structure when being discharged; when the air guide blades 222 are in the second position, the air guide blades 222 have a small resistance to the air flow passing through the air guide channel 23, thereby allowing the air flow on the front side of the air guide component 21 to quickly pass through the air guide channel 23 to reduce the wind resistance of the vehicle at the air guide component 21, which is beneficial to improving the aerodynamic performance of the vehicle.

[0041] In some embodiments, the air guide blade 222 may be located in the middle of the first position and the second position, that is, in the direction from front to back, the air guide blade 222 extends upwardly at an angle relative to the extension direction of the air guide channel 23. Therefore, the air guide blade 222 may block debris from passing through the air guide channel 23, while part of the air flow may pass through the air guide channel 23, thereby improving the aerodynamic performance of the vehicle while blocking debris.

[0042] Specifically, when there are a large amount of debris on the road, the drive unit 221 drives the air guide blade 222 to rotate to the first position, and the air guide blade 222 completely closes the air guide channel 23, thereby preventing debris from entering the air guide channel 23 and damaging the air guide channel 23, and at the same time preventing debris from being discharged from the air guide channel 23 and damaging the vehicle body structure; when the road condition is good and the vehicle speed is fast, such as when the vehicle speed is greater than or equal to 100 km / h, the drive unit 221 drives the air guide blade 222 to rotate to the second position, and the area of ​​the airflow blocked by the air guide blade 222 is smaller, thereby improving the aerodynamic performance of the vehicle; when there are fewer debris on the road and the vehicle speed is faster, such as when the vehicle speed is greater than or equal to 100 km / h, the drive unit 221 drives the air guide blade 222 to rotate to the middle position between the first position and the second position, thereby blocking debris while improving the aerodynamic performance of the vehicle.

[0043] Of course, the driving unit 221 can also drive the air guide blade 222 to rotate to a state where it is tilted downward from the front to the back relative to the extension direction of the air guide channel 23. There is no specific restriction on the angle at which the air guide blade 222 can be tilted relative to the extension direction of the energy guiding channel 23.

[0044] According to some embodiments of the utility model, the driving unit 221 includes a driving motor 2211 and a transmission connecting rod 2212, the transmission connecting rod 2212 extends in the up-down direction and is connected to the plurality of air guide blades 222, and the driving motor 2211 is used to drive the transmission connecting rod 2212 to move in the up-down direction. In other words, the up-down movement of the transmission connecting rod 2212 can simultaneously drive the plurality of air guide blades 222 to rotate, so as to adjust the inclination angle of the plurality of air guide blades 222 relative to the extension direction of the air guide channel 23, thereby improving the consistency of the rotation of the plurality of air guide blades 222, and at the same time simplifying the transmission structure of the driving unit 221, thereby reducing the number of parts of the driving unit 221, which is conducive to reducing the cost of the driving unit 221.

[0045] In a specific embodiment, the driving unit 221 also includes a rotating main shaft 2213 extending in the left-right direction, the rotating main shaft 2213 is perpendicular to the transmission connecting rod 2212, and the rotating main shaft 2213 can drive the transmission connecting rod 2212 to move up and down by its own rotation. The rotating main shaft 2213 is provided with a first spline, and the output shaft of the driving motor 2211 is provided with a transmission gear, which is meshed with the first spline. Therefore, the driving motor 2211 can drive the transmission gear to rotate through the output shaft, and the transmission gear drives the rotating main shaft through the first spline. 2213 rotates, thereby driving the transmission link 2212 to move up and down, thereby adjusting the inclination angle of the air guide blade 222 relative to the extension direction of the air guide channel 23. At the same time, the transmission link 2212 is formed with a second spline, and the rotation axis of the air guide blade 222 is provided with a third spline meshing with the second spline. Therefore, when the transmission link 2212 moves up and down, the third spline can drive the air guide blade 222 to rotate around its rotation axis through the second spline, thereby adjusting the angle between the air guide blade 222 and the extension direction of the air guide channel 23.

[0046] According to some embodiments of the utility model, the drive unit 221 is located outside the wind guide channel 23 and inside the wind guide component 21. That is, the drive unit 221 is located on the side of the wind guide component 21 away from the fender 1 in the left-right direction. Therefore, the drive unit 221 can be prevented from interfering with the wind guide blades 222 in the wind guide channel 23, which facilitates the movement of the wind guide blades 222. At the same time, the drive unit 221 is prevented from interfering with the fender 1 located outside the wind guide channel 23, providing sufficient installation space for the drive unit 221, and facilitating the installation of the drive unit 221.

[0047] According to some embodiments of the utility model, the air guide blade 222 is arranged at the air inlet 24. Therefore, when the air guide blade 222 is located at the first position, debris can be intercepted at the entrance of the air guide channel 23, so that the air guide blade 222 can prevent the debris from entering the air guide channel 23 and accumulating, thereby preventing the debris from accumulating in the air guide channel 23 and causing resistance to the airflow, which is beneficial to improving the aerodynamic performance of the vehicle. At the same time, it can prevent the debris from entering the air guide channel 23 and colliding with the part of the air guide channel 23 formed by the fender 1 to produce abnormal noise. For example, the air guide channel 23 is composed of the air guide component 21 and the fender 1. The air guide blade 222 located at the first position can prevent the debris from colliding with the air guide component 21 and the fender 1 to produce abnormal noise, which is beneficial to improving the quietness of the vehicle.

[0048] According to some embodiments of the utility model, in the extension direction of the air guide channel 23, the length L1 of the air guide blade 222 and the length L2 of the air guide channel 23 satisfy: L1 / L2≤0.5. That is to say, the length of the air guide blade 222 in the extension direction of the air guide channel 23 is controlled within the range of half or less of the length of the air guide channel 23. It can be understood that, when the length of the air guide channel 23 remains unchanged, the greater the ratio of the length of the air guide blade 222 in the extension direction of the air guide channel 23 to the length of the air guide channel 23, the longer the length of the air guide blade 222 in the extension direction of the air guide channel 23, the better the effect of the air guide blade 222 in intercepting debris, but at the same time, the greater the wind resistance generated by the airflow through the air guide blade 222 and the higher the cost. Therefore, by controlling the ratio of the length of the air guide blade 222 in the extension direction of the air guide channel 23 to the length of the air guide channel 23 within a range of not more than 0.5, the wind resistance of the air guide blade 222 to the air flow can be reduced while ensuring the interception effect of the air guide blade 222 on the debris, and it is helpful to reduce the cost of the air guide blade 222. Among them, the ratio of the length L1 of the air guide blade 222 to the length L2 of the air guide channel 23 can be 0.2, 0.26, 0.3, 0.34, 0.4, 0.47, 0.5, etc., which is not specifically limited here.

[0049] According to some embodiments of the utility model, the cross section of the air guide component 21 in the front-to-back direction is C-shaped and is open toward the inner side surface of the fender 1, and the air guide channel 23 is defined between the air guide component 21 and the inner side surface of the fender 1. In other words, the air guide component 21 is formed into a structure that is open toward the inner side surface of the fender 1 and is through in the front-to-back direction, and the inner side surface of the fender 1 forms the air guide channel 23 extending in the front-to-back direction by blocking the open opening of the air guide component 21 toward the fender 1. Thus, while ensuring that the air guide channel 23 can be formed on the inner side of the fender 1 to reduce the wind resistance during the driving of the vehicle, the fender 1 can replace the structure of the open opening of the air guide component 21 toward the fender 1, so that the structure of the open opening of the air guide component 21 toward the fender 1 can be omitted, and then the structure of the air guide component 21 can be simplified, which is conducive to reducing the cost of the air guide component 21.

[0050] In some embodiments, the wind guide component 21 includes a side panel 211, a first side panel 212 and a second side panel 213. The side panel 211 is spaced apart from the inner side surface of the fender 1, and the first side panel 212 and the second side panel 213 are spaced apart in the up and down directions. In the left and right directions, one end of the first side panel 212 and the second side panel 213 are connected to the side panel 211, and the other ends of the first side panel 212 and the second side panel 213 extend toward a direction close to the fender 1. That is, in the left-right direction, the end of the first side panel 212 away from the fender 1 and the end of the second side panel 213 away from the fender 1 are connected by the side panel 211, and the inner side surface of the fender 1 is used to block the space between the end of the first side panel 212 away from the side panel 211 and the end of the second side panel 213 away from the side panel 211, so as to form an air guide channel 23 extending in the front-back direction, that is, the side surface of the side panel 211 facing the fender 1, the side surface of the first side panel 212 facing the second side panel 213, the side surface of the second side panel 213 facing the first side panel 212 and the inner side surface of the fender 1 jointly define the air guide channel 23. As a result, the air guide component 21 can omit the structure connecting the end of the first side panel 212 away from the side panel 211 and the end of the second side panel 213 away from the side panel 211, so that the structure of the air guide component 21 can be simplified, which is conducive to reducing the cost of the air guide component 21.

[0051] In a specific example, the side panel 211 is roughly perpendicular to the left and right directions, the first side panel 212 and the second side panel 213 are respectively arranged at the upper and lower ends of the side panel 211 and have roughly the same length as the side panel 211 in the front-to-back direction, in the left and right directions, one end of the first side panel 212 is connected to the upper end of the side panel 211, the other end of the first side panel 212 extends toward the direction close to the fender 1 and abuts against the inner side surface of the fender 1, one end of the second side panel 213 is connected to the lower end of the side panel 211, the other end of the second side panel 213 extends toward the direction close to the fender 1 and abuts against the inner side surface of the fender 1, the distance between the first side panel 212 and the second side panel 213 in the up-down direction is greater than the distance between the side panel 211 and the fender 1, so that the cross-section of the air guide channel 23 in the front-to-back direction is formed into a long strip extending along the up-down direction.

[0052] In some embodiments, the air guide component 21 is an integrally formed part. Thus, the integrally formed structure can not only ensure the performance stability of the side panels 211, the first side panels 212, and the second side panels 213 of the air guide component 21, but also facilitates molding and is simple to manufacture. Moreover, the assembly parts and connection procedures used to connect the side panels 211, the first side panels 212, and the second side panels 213 are omitted, the production cost is low, and the assembly efficiency of the side panels 211, the first side panels 212, and the second side panels 213 is greatly improved, and the connection reliability of the side panels 211, the first side panels 212, and the second side panels 213 is ensured. Furthermore, the integrally formed structure has high overall strength and stability and a longer service life.

[0053] A vehicle body assembly 100 according to an embodiment of a second aspect of the present invention will be described below with reference to the accompanying drawings.

[0054] According to the second embodiment of the utility model, the vehicle body assembly 100 comprises: a fender 1, an air guide structure 2, a mud guard 3 and a vehicle door 4, wherein the mud guard 3 is located at the front side of the fender 1 and is provided with a vent 31 connected to the air inlet 24, and the vehicle door 4 is located at the rear side of the fender 1 and defines an exhaust port 41 connected to the air outlet 25 between the fender 1 and the fender 1. That is, the vent 31 is connected to the air guide channel 23 through the air inlet 24, and the air guide channel 23 is connected to the exhaust port 41 through the air outlet 25, that is, a connected air flow channel can be formed between the vent 31, the air inlet 24, the air guide channel 23, the air outlet 25 and the exhaust port 41, so that the air flow on the front side of the mud guard 3 can flow to the rear side of the fender 1 through the vent 31, the air inlet 24, the air guide channel 23, the air outlet 25 and the exhaust port 41 in sequence, so that the wind resistance at the fender 3 can be well reduced, which is conducive to improving the aerodynamic performance of the vehicle.

[0055] Among them, the wind guide structure 2 is arranged on the inner side of the fender 1 and includes an wind guide component 21 and an wind guide mechanism 22. The wind guide mechanism 22 includes a driving unit 221 and a plurality of wind guide blades 222 arranged in the up and down directions in the wind guide channel 23. The wind guide blades 222 are rotatable relative to the wind guide channel 23 and the rotation axis of the wind guide blades 222 extends in the left and right directions. The driving unit 221 is used to drive the plurality of wind guide blades 222 to rotate. That is to say, the driving unit 221 can change the inclination angle of the air guide blade 222 relative to the extension direction of the air guide channel 23 by driving the air guide blade 222 to rotate. For example, the driving unit 221 can drive the air guide blade 222 to rotate to a position roughly parallel to the extension direction of the air guide channel 23. At this time, the air guide blade 222 has little resistance to the airflow passing through the air guide channel 23, so that the airflow on the front side of the fender 3 can quickly flow through the air guide channel 23 to the rear side of the fender 1 to reduce the wind resistance at the fender 3, which is beneficial to improving the aerodynamic performance of the vehicle; the driving unit 221 can also drive the air guide blade 222 to rotate to a position roughly perpendicular to the extension direction of the air guide channel 23. At this time, the air guide blade 222 can block debris such as stones, mud blocks, etc. from moving backward along the air guide channel 23 with the air flow, thereby preventing the debris from scratching the vehicle door 4 and other body structures when being discharged through the air outlet 25 and the exhaust port 41.

[0056] According to the vehicle body assembly 100 of the second aspect of the utility model, the angle between the air guide blade 222 and the extension direction of the air guide channel 23 can be adjusted by the driving unit 221 according to the condition of the driving road surface. While reducing the wind resistance at the fender 3, it can prevent debris on the front side of the fender 3 from moving through the air guide channel 23 to the door 4 and scratching the door 4, thereby improving the aerodynamic performance of the vehicle while reducing the risk of damage to the door 4.

[0057] The vehicle door 4 is a vehicle door 4 on the front side of the vehicle, and the fender 3 is a fender 3 of the front wheel of the vehicle.

[0058] In some embodiments, the vent 31 can be completely formed on the fender 3, and the vent 31 can also be jointly defined by the inner side surfaces of the fender 3 and the fender 1. For example, a gap open toward the inner side surface of the fender 1 is formed on the fender 3, and the inner side surface of the fender 1 blocks the opening of the gap to form the vent 31.

[0059] According to some embodiments of the utility model, a sealing member is provided between the air guide member 21 and the inner side surface of the fender 1. Therefore, the sealing member can improve the sealing effect between the air guide member 21 and the inner side surface of the fender 1 by filling between the air guide member 21 and the fender 1, thereby preventing the gas in the air guide channel 23 from escaping through the gap between the air guide member 21 and the fender 1 to affect the airflow guiding effect of the air guide channel 23, and the direct contact between the air guide member 21 and the fender 1 can be avoided by the sealing member, thereby avoiding friction damage and noise caused by the contact.

[0060] In some embodiments, the seal may be foam, which has good sealing performance and good buffering and shock absorbing effects, thereby improving the sealing between the air guide component 21 and the fender 1 while having a good buffering effect between the air guide component 21 and the fender 1.

[0061] According to some embodiments of the utility model, the inner side of the fender 1 is further provided with a mounting bracket 11, the air guide component 21 is provided on the mounting bracket 11, and the fender 3 has at least two parts that are directly connected to the mounting bracket 11 and the air guide component 21 respectively. That is to say, the air guide component 21 is connected to the fender 1 and the fender 3 through the mounting bracket 11 provided on the inner side of the fender 1, and at the same time, the air guide component 21 is also directly connected to the fender 3. In this way, the installation and fixing position of the air guide component 21 can be increased to improve the stability of the air guide component 21 after installation. In a specific example, the fender 1 fixes the mounting bracket 11 by hemming and threaded fasteners, which is conducive to reducing the difficulty of installing the mounting bracket 11.

[0062] According to some embodiments of the utility model, the vehicle body assembly 100 further includes a vehicle body side 5 and a side trim 6. The fender 1 and the door 4 are arranged on the outside of the vehicle body side 5. The inner side of the fender 1 is further provided with a mounting bracket 11. The side trim 6 is located between the vehicle body side 5 and the fender 1 and is connected to the vehicle body side 5, the mounting bracket 11 and the air guide component 21 at the same time. The side trim 6 is located between the door 4 and the air guide component 21 and defines an air outlet 61 connecting the air outlet 25 and the air outlet 41 with the inner side of the fender 1. That is, the side trim 6 is connected to the fender 1 through the mounting bracket 11 and is connected to the vehicle body side 5 and the air guide component 21 at the same time, thereby increasing the connection position of the fender 1, the vehicle body side 5 and the air guide component 21, improving the reliability of the connection between the fender 1, the vehicle body side 5 and the air guide component 21, and the side trim 6 can better cover the gap between the fender 1 and the vehicle body side 5, and has a good protective effect on the structure between the fender 1 and the vehicle body side 5.

[0063] The side trim 6 is located between the vehicle door 4 and the air guide component 21 and defines an air passage 61 connecting the air outlet 25 and the air outlet 41 with the inner side surface of the fender 1. That is, the air outlet 25 is connected with the air outlet 41 through the air passage 61. Therefore, the airflow entering the air guide channel 23 can be discharged through the air outlet 25, the air passage 61 and the air outlet 41 to avoid the side trim 6 blocking the flow of air, which is conducive to improving the stability of the air guide of the fender 1.

[0064] In some embodiments, the side trim panel 6 includes a trim panel body and a mating part provided on the trim panel body. The hardness of the mating part is less than that of the trim panel body. The mating part is interference fit with the fender 1 and the body side 5. The trim panel body and the mating part are two-color injection molded.

[0065] In some embodiments, the projection of the air outlet 25 on the reference plane is located within the projection of the air outlet 61 and the air outlet 41 on the reference plane, and the reference plane is perpendicular to the extension direction of the air guide channel 23. In this way, it is possible to better avoid the side trim 6, the door 4 and the fender 1 from blocking the air outlet in the air guide channel 23, so as to improve the air outlet efficiency of the air guide channel 23.
