Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, specifically to a front suspension underbody protection plate and a vehicle. Background Technology

[0002] With the development of vehicle technology, consumers have increasingly higher demands for vehicle handling performance. Among these, the vehicle's lift coefficient is a crucial factor affecting handling performance. In related technologies, vehicle underbody protection plates are typically flat structures; however, these structures offer limited improvement in overall downforce performance, resulting in relatively poor handling. Utility Model Content

[0003] This utility model aims to at least partially solve one of the technical problems in the related art.

[0004] Therefore, embodiments of this utility model propose a front suspension underbody protection plate, which can turbulentize the airflow in the front axle area of ​​the vehicle, increase downforce, increase the downforce coefficient of the front axle of the vehicle, and improve the handling of the vehicle.

[0005] An embodiment of this utility model also proposes a vehicle.

[0006] The front suspension underbody protection plate of this utility model includes: a protection plate body and a spoiler. The spoiler is disposed on the lower wall surface of the protection plate body and on at least one side of the protection plate body in the left-right direction. The spoiler is arranged close to the rear side of the protection plate body. The spoiler includes a spoiler rib, which extends along the front-rear direction of the protection plate body and protrudes downward.

[0007] According to an embodiment of the present invention, the front suspension underbody guard plate has a deflector located on at least one side of the guard plate body in the left-right direction, and the deflector is arranged close to the rear side of the guard plate body. Therefore, the deflector can turbulentize the flow field in the rear area of ​​the guard plate body along the left-right direction, preventing turbulence in the middle of the guard plate body and facilitating normal rearward flow of air in the middle of the guard plate body. Furthermore, since the deflector ribs extend along the front-rear direction of the guard plate body and protrude downwards, when airflow passes over the lower wall of the guard plate body in a front-to-back direction, the deflector ribs can turbulentize the airflow field, generating vortices in the area where the deflector ribs are arranged and accelerating local airflow, thereby reducing the pressure in that area and generating negative pressure. Therefore, the front suspension underbody guard plate of this embodiment can turbulentize the airflow in the front axle area of ​​the vehicle, increasing downforce, increasing the downforce coefficient of the front axle, and improving vehicle handling.

[0008] In some embodiments, the guard plate body has a first side and a second side arranged opposite to each other in the left-right direction, and the deflector includes a first deflector arranged close to the first side, the first deflector extending obliquely toward the first side in a direction from front to back.

[0009] In some embodiments, the angle between the extension direction of the first rib and the front-back direction is α, where 0 < α ≤ 45°.

[0010] In some embodiments, in a projection plane orthogonal to the thickness direction of the guard plate body, the extension path of the first baffle is a curve, and the center of curvature of the curve is located on the side of the first baffle closer to the first side.

[0011] In some embodiments, there are multiple first deflector ribs, and the multiple first deflector ribs are arranged at intervals along the left-right direction.

[0012] In some embodiments, the lower end faces of the plurality of the first ribs are located at the same horizontal height.

[0013] In some embodiments, the deflector includes a first substrate, the first substrate being detachably connected to the guard plate body, and the first deflector rib being disposed on the first substrate.

[0014] In some embodiments, the lower wall surface of the protective plate body is provided with a recessed groove, and the first substrate is installed in the recessed groove.

[0015] In some embodiments, the baffle further includes a reinforcing rib disposed on the side of the first substrate near the protective plate body.

[0016] In some embodiments, there are multiple reinforcing ribs, which are arranged crosswise on the side of the first substrate near the protective plate body.

[0017] In some embodiments, there is an installation gap between the reinforcing rib and the protective plate body.

[0018] In some embodiments, the deflector includes a second deflector, which is arranged close to the second side and extends at an angle towards the second side from front to back.

[0019] In some embodiments, the first side and the second side are arranged symmetrically about the longitudinal symmetry plane, the first baffle and the second baffle are symmetrical about the longitudinal symmetry plane, and the minimum distance between either the first baffle and the second baffle along the left-right direction and the longitudinal symmetry plane is L, wherein L≥150mm.

[0020] In some embodiments, the maximum protrusion height of at least one of the first and second baffle ribs along the thickness direction of the guard plate body is H, wherein 20mm≤H≤30mm.

[0021] In some embodiments, the baffle ribs are made of soft plastic.

[0022] Another embodiment of the present invention includes a vehicle body, the vehicle body including a front suspension; a front suspension underbody protection plate, the front suspension underbody protection plate being the front suspension underbody protection plate as described in any one of the embodiments of the present invention, the front suspension underbody protection plate being installed on the underside of the front suspension.

[0023] According to an embodiment of the present invention, since the spoiler is located on at least one side of the skid plate body in the left-right direction and is arranged near the rear side of the skid plate body, the spoiler can turbulentize the flow field in the rear area of ​​the skid plate body in the left-right direction. This prevents turbulence in the middle of the skid plate body and facilitates normal rearward flow of air in the middle of the skid plate body. Furthermore, since the spoiler ribs extend along the front-rear direction of the skid plate body and protrude downwards, when airflow passes over the lower wall of the skid plate body from front to back, the spoiler ribs can turbulentize the airflow field, generating vortices in the area where the spoiler ribs are arranged and accelerating local airflow, thereby reducing the pressure in that area and creating negative pressure. Therefore, the front suspension underbody skid plate of the vehicle according to an embodiment of the present invention can turbulentize the airflow in the front axle area, increase downforce, increase the downforce coefficient of the front axle, and improve vehicle handling.

[0033] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0034] The following is a reference appendix. Figures 1 to 5 This invention describes a front suspension underbody protection plate and a vehicle according to an embodiment of the present invention.

[0035] like Figures 1 to 3 As shown, the front suspension underbody guard plate of this utility model embodiment includes: a guard plate body 100 and a spoiler 200. The spoiler 200 is disposed on the lower wall surface of the guard plate body 100 and at least one side of the guard plate body 100 in the left-right direction. The spoiler 200 is arranged close to the rear side of the guard plate body 100. The spoiler 200 includes a spoiler rib 201, which extends along the front-rear direction of the guard plate body 100 and protrudes downward.

[0036] It should be noted that the front suspension underbody protection plate is aligned with the front, rear, left, right, up, and down directions of the vehicle.

[0037] According to an embodiment of the present invention, the front suspension underbody guard plate, since the deflector 200 is disposed on at least one side of the guard plate body 100 in the left-right direction and is arranged close to the rear side of the guard plate body 100, can turbulentize the flow field of the guard plate body 100 in the rear area along the left-right direction. This can prevent turbulence in the flow field at the middle position of the guard plate body 100 and facilitate the normal rearward flow of air in the middle position of the guard plate body 100. In addition, since the deflector rib 201 extends along the front-rear direction of the guard plate body 100 and protrudes downward, when the airflow flows from front to back across the lower wall of the guard plate body 100, the deflector rib 201 can turbulentize the airflow field, thereby generating vortices in the area where the deflector rib 201 is arranged and accelerating the local airflow, thereby reducing the pressure in that area and generating negative pressure.

[0038] Therefore, the front suspension underbody protection plate of this utility model can turbulentize the airflow in the front axle area of ​​the vehicle, increase downforce, increase the downforce coefficient of the front axle of the vehicle, and improve the handling of the vehicle.

[0039] The front axle of a vehicle can be understood as the front drive axle, which connects to the left and right front wheels. A front suspension underbody protection plate is installed under the front axle to shield and protect the axle and some components of the front suspension, reducing the probability of the axle or suspension being damaged in impacts.

[0040] It is understandable that the airflow in the rear area on both sides of the guard plate body 100 is prone to change. By placing the spoiler 200 close to the rear area on both sides of the guard plate body 100, the airflow that is about to change can be sorted and turbulent, which is beneficial to increasing the downforce in the front axle area of ​​the vehicle.

[0041] For example, the spoiler 200 is located on the left side and rearward of the guard plate body 100. For example, the spoiler 200 is located on the right side and rearward of the guard plate body 100. And for another example... Figure 1 As shown, some of the spoilers 200 are located on the left side and rear of the guard plate body 100, while the other part of the spoilers 200 are located on the right side and rear of the guard plate body 100.

[0042] Compared to the solution of "setting the spoiler 200 in the middle position of the guard plate body 100 in the left-right direction", the front suspension under guard plate of this utility model can avoid interfering with the airflow flowing through the middle position of the guard plate body 100, thereby reducing the problem of turbulence when the airflow passes through the rear suspension under guard plate, reducing driving resistance, and helping to increase the downforce of the vehicle.

[0043] Optionally, such as Figure 1 As shown, the skid plate body 100 has a first side 101 and a second side 102 arranged opposite to each other in the left-right direction. The deflector rib 201 includes a first deflector rib 2011, which is arranged close to the first side 101 and extends gradually towards the first side 101 in a front-to-back direction. It can be understood that the first deflector rib 2011 can guide airflow to the area of ​​the first side 101 of the skid plate body 100. That is, the first deflector rib 2011 can guide the airflow at the bottom of the skid plate body 100 outward (to the first side 101) to improve the uniformity of the airflow at the bottom of the skid plate body 100 in the Y direction (left-right direction), increase the deflection range of the deflector 200, and increase the downforce in the front axle area of ​​the vehicle.

[0044] like Figure 1 As shown, the angle between the extension direction of the first spoiler 2011 and the front-back direction is α, where 0 < α ≤ 45°. That is, the deflection angle of the first spoiler 2011 is selected between 0 and 45°, which can improve the uniformity of airflow distribution. For example, α can be 1°, 10°, 20°, 30°, 40°, or 45°.

[0045] Optionally, in the projection plane orthogonal to the thickness direction of the guard plate body 100, the extension path of the first deflector 2011 is a curve, and the center of curvature of the curve is located on the side of the first deflector 2011 close to the first side 101, thereby further improving the airflow guiding effect and reducing air resistance.

[0046] Optionally, there are multiple first deflector ribs 2011, which are arranged at intervals in the left and right direction. This can expand the deflection range of the first deflector ribs 2011 and increase the downforce in the front axle area of ​​the vehicle.

[0047] like Figure 4 As shown, the lower ends of multiple first deflector ribs 2011 are located at the same horizontal height. It can be understood that the different first deflector ribs 2011 are spaced equidistant from the ground. This further enhances the deflection effect of the first deflector ribs 2011 on the airflow field, thereby accelerating local airflow and generating a larger negative pressure in the area where the first deflector ribs 2011 are arranged, thus increasing the downforce coefficient of the vehicle's front axle.

[0048] In some embodiments, such as Figures 1 to 3 As shown, the spoiler 200 includes a first base plate 202, which is detachably connected to the underbody 100. A first spoiler rib 2011 is disposed on the first base plate 202. It can be understood that the first spoiler rib 2011 is connected to the underbody 100 through the first base plate 202. The first base plate 202 can not only serve as a connector for the first spoiler rib 2011 to facilitate its installation and removal, but also increase the structural strength of the corresponding mounting area of ​​the underbody 100, improve the impact resistance of the underbody 100, and extend the service life of the front suspension underbody.

[0049] like Figure 2 and Figure 3 As shown, the first base plate 202 and the guard plate body 100 can be connected by rivets or threaded fasteners. For example, the first base plate 202 is provided with a plurality of fixing holes 2021 for threaded fasteners to pass through. The threaded fasteners can be connected to the guard plate body 100 and the subframe at the same time to improve the fixing effect of the spoiler 200.

[0050] For example, such as Figure 3 As shown, the first substrate 202 is provided with a plurality of rivet holes 2022 so that the first substrate 202 can be riveted to the protective plate body 100.

[0051] For example, the thickness of the first substrate 202 is within 2.5 mm to avoid the problem that the turbulence-disrupting effect of the turbulence-disrupting element 200 will decrease due to the excessive thickness of the first substrate 202.

[0052] Optionally, such as Figure 2 As shown, the lower wall surface of the underbody 100 is provided with a recess 103, and the first substrate 202 is installed in the recess 103. For example, when the first substrate 202 is installed in the recess 103, the lower wall surface of the first substrate 202 is substantially flush with the lower wall surface of the underbody 100, or the lower wall surface of the first substrate 202 protrudes slightly from the lower wall surface of the underbody 100. This allows for structural adjustments to the first substrate 202, improving the overall integrity of the front suspension underbody structure and providing a better aerodynamic effect.

[0053] Optionally, such as Figure 5 As shown, the spoiler 200 also includes a reinforcing rib 204, which is disposed on the side of the first substrate 202 near the protective plate body 100. It can be understood that the reinforcing rib 204 is disposed on the upper wall surface of the first substrate 202. Because the reinforcing rib 204 is disposed on the upper wall surface of the first substrate 202, compared to a solution where the reinforcing rib 204 is disposed on the lower wall surface of the first substrate 202, wind resistance can be reduced, and the spoiler 200's spoiler effect can be improved. In addition, the reinforcing rib 204 can strengthen the structure of the first substrate 202, thereby improving the first substrate 202's impact resistance and extending the service life of the spoiler 200.

[0054] For example, there are multiple reinforcing ribs 204, which are arranged crosswise on the side of the first substrate 202 near the protective plate body 100 to further improve the structural strength of the first substrate 202. Exemplarily, the reinforcing ribs 204 can be a grid-like, radial, or honeycomb structure.

[0055] There is an installation gap between the upper side of the reinforcing rib 204 and the lower wall surface of the guard plate body 100. After the first base plate 202 is installed into the recess 103, the reinforcing rib 204 can be spaced apart from the lower wall surface of the guard plate body 100, thereby reducing the probability of abnormal noise at the connection position between the baffle 200 and the guard plate body 100.

[0056] For example, the installation gap between the upper side of the reinforcing rib 204 and the lower wall of the guard plate body 100 is about 1 mm.

[0057] Optionally, such as Figure 1As shown, the spoiler rib 201 includes a second spoiler rib 2012, which is arranged close to the second side 102. The second spoiler rib 2012 extends gradually towards the second side 102 in a front-to-back direction. It can be understood that the second spoiler rib 2012 can guide airflow to the area of ​​the second side 102 of the guard plate body 100. That is, the second spoiler rib 2012 can guide the airflow at the bottom of the guard plate body 100 outward (to the second side 102), thereby improving the uniformity of the airflow at the bottom of the guard plate body 100 in the Y direction (left-right direction), increasing the spoiler range of the spoiler 200, and increasing the downforce in the front axle area of ​​the vehicle.

[0058] like Figure 1 As shown, the first side 101 and the second side 102 are symmetrically arranged about the longitudinal symmetry plane P. The first spoiler rib 2011 and the second spoiler rib 2012 are also symmetrical about the longitudinal symmetry plane P. The minimum distance between either the first spoiler rib 2011 or the second spoiler rib 2012 and the longitudinal symmetry plane P in the left-right direction is L, where L ≥ 150 mm. This avoids interfering with the airflow passing through the middle position of the guard plate body 100, thereby reducing turbulence when the airflow passes through the rear suspension underbody guard plate, reducing driving resistance, and increasing vehicle downforce.

[0059] In this example, the front axle downforce coefficient can be increased by 0.015 to significantly improve vehicle handling.

[0060] Optionally, such as Figure 4 As shown, at least one of the first baffle 2011 and the second baffle 2012 is along the thickness direction of the protective plate body 100 (e.g., Figure 4 The maximum protrusion height (vertical direction) is H, where 20mm ≤ H ≤ 30mm. When H is less than 20mm, the first spoiler rib 2011 and the second spoiler rib 2012 have poor airflow turbulence effect and little impact on the front axle downforce of the vehicle. When H is greater than 30mm, on the one hand, it will result in limited ability to increase the front axle downforce of the vehicle; on the other hand, it will cause the lower ends of the first spoiler rib 2011 and the second spoiler rib 2012 to be too close to the ground, making them prone to collisions and reducing the service life of the spoiler 200.

[0061] like Figure 1As shown, the deflector 200 also includes a second substrate 203, and the second deflector rib 2012 is detachably connected to the guard plate body 100 via the second substrate 203. For example, the first substrate 202 and the first deflector rib 2011 are formed by two-color injection molding. The second substrate 203 and the second deflector rib 2012 are also formed by two-color injection molding. The deflector rib 201 (the first deflector rib 2011 and the second deflector rib 2012) are made of soft plastic, which reduces the probability of the first deflector rib 2011 and the second deflector rib 2012 being damaged by impact.

[0062] Optionally, the thickness of the lower end region of either the first bleeder 2011 or the second bleeder 2012 is controlled within 3 mm to avoid the problem that the bleeder effect of the bleeder is reduced due to the excessive thickness of the lower end of the first bleeder 2011 or the second bleeder 2012.

[0063] Another embodiment of the present invention includes a vehicle body and a front suspension underbody protection plate. The vehicle body includes a front suspension, and the front suspension underbody protection plate is the front suspension underbody protection plate of the present invention, which is installed on the lower side of the front suspension.

[0064] The front suspension underbody protection plate of this utility model can turbulentize the airflow in the front axle area of ​​the vehicle, increase downforce, increase the downforce coefficient of the front axle, and improve the vehicle's handling.
