Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, specifically to a front 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 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, and improve the vehicle's handling.

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

[0006] The front bumper guard of this utility model includes: a guard body having a first side and a second side arranged opposite to each other in a front-rear direction, the first side being located in front of the second side; and a spoiler disposed on the lower wall surface of the guard body, the spoiler extending in a left-right direction along the guard body and protruding downward, the spoiler being arranged close to the first side.

[0007] According to an embodiment of the present invention, the front bumper guard plate has a deflector located on the lower wall of the guard plate body. The deflector extends along the left-right direction of the guard plate body and protrudes downward. When airflow passes over the lower wall of the guard plate body from front to back, the deflector can block part of the airflow from flowing backward, creating a vacuum zone in the area behind the deflector. Simultaneously, the airflow can accelerate past the deflector to generate negative pressure, thereby increasing the downforce on the front axle of the vehicle. Furthermore, because the deflector is positioned close to the first side, its deflection effect is enhanced. Therefore, the front bumper guard plate of this embodiment can deflect 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 first side has a front bumper mounting area, and in the front-rear direction, the distance between the spoiler and the rear edge of the front bumper mounting area is L, wherein 13mm≤L≤23mm.

[0009] In some embodiments, the guard plate body has a third side and a fourth side arranged opposite to each other along the left-right direction, one end of the spoiler extends to the third side along the left-right direction, and the other end of the spoiler extends to the fourth side along the left-right direction.

[0010] In some embodiments, the various positions of the lower end face of the spoiler are located at the same horizontal height.

[0011] In some embodiments, the maximum protrusion height of the spoiler in the vertical direction is H, wherein 40mm≤H≤50mm.

[0012] In some embodiments, the spoiler is detachably connected to the guard plate body.

[0013] In some embodiments, the spoiler includes a horizontal plate and a vertical plate connected together. The thickness direction of the horizontal plate is parallel to the vertical direction of the guard plate body, and the thickness direction of the vertical plate is perpendicular to the vertical direction of the guard plate body. The horizontal plate is connected to the guard plate body, and the vertical plate is located on the front side of the horizontal plate and protrudes downward.

[0014] In some embodiments, the spoiler further includes reinforcing ribs connected to the upper wall of the horizontal plate and the rear wall of the vertical plate.

[0015] In some embodiments, the horizontal plate has a connecting hole extending through the vertical direction, and the front bottom guard plate further includes a fastener that passes through the connecting hole and the guard plate body.

[0016] In some embodiments, the upper wall of the horizontal plate is provided with a locking block, which engages with the protective plate body.

[0017] In some embodiments, a chamfer is provided at the junction of one side of the vertical plate along its thickness direction and the lower end face of the vertical plate, and the radius of the chamfer is R, where 0 < R ≤ 1 mm.

[0018] Another embodiment of the present invention includes a vehicle body and a front underbody protection plate. The vehicle body includes a front bumper, and the front underbody protection plate is the same as any one of the embodiments of the present invention. The front underbody protection plate is located on the lower side of the front bumper, and the first side is connected to the front bumper.

[0019] According to an embodiment of the present invention, the vehicle's front bumper guard, with its aerodynamic component located on the lower wall of the guard plate body, extends along the left-right direction and protrudes downwards. When airflow passes over the lower wall of the guard plate body from front to back, the aerodynamic component can block some of the airflow from flowing backwards, creating a vacuum zone in the area behind the aerodynamic component. Simultaneously, the airflow can accelerate past the aerodynamic component to generate negative pressure, thereby increasing the downforce on the front axle of the vehicle. Furthermore, because the aerodynamic component is positioned close to the first side, its aerodynamic effect is enhanced. Therefore, the front bumper guard of the vehicle according to this embodiment of the present invention can turbulentize the airflow in the front axle area, increasing downforce, increasing the downforce coefficient of the front axle, and improving vehicle handling.

[0029] 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.

[0030] The following is a reference appendix. Figures 1 to 6This invention describes a front underbody protection plate and a vehicle according to an embodiment of the present invention.

[0031] like Figures 1 to 4 As shown, the front bumper guard of this utility model embodiment includes: a guard body 100 and a spoiler 200. The guard body 100 has a first side 101 and a second side 102 arranged opposite to each other in the front-rear direction. The first side 101 is located in front of the second side 102. The spoiler 200 is disposed on the lower wall surface of the guard body 100. The spoiler 200 extends in the left-right direction of the guard body 100 and protrudes downward. The spoiler 200 is arranged close to the first side 101.

[0032] It should be noted that the front underbody protection plate's front, rear, left, right, up, and down directions are consistent with the vehicle's front, rear, left, right, up, and down directions. Specifically, the first side 101 is the front side of the protection plate body 100, and the second side 102 is the rear side of the protection plate body 100. The first side 101 of the protection plate body 100 is used to connect to the front bumper (not shown). The spoiler 200 can also be referred to as an "air dam".

[0033] According to the embodiment of the present invention, the front bumper guard plate has a spoiler 200 disposed on the lower wall surface of the guard plate body 100. The spoiler 200 extends along the left and right direction of the guard plate body 100 and protrudes downward. When the airflow flows from the lower wall surface of the guard plate body 100 in the direction from front to back, the spoiler 200 can block part of the airflow from flowing backward, so as to form a vacuum zone in the rear area of ​​the spoiler 200. At the same time, the airflow can accelerate through the spoiler 200 to generate negative pressure, thereby increasing the downforce on the front axle of the vehicle. Furthermore, since the spoiler 200 is arranged close to the first side 101, the spoiler effect of the spoiler 200 can be enhanced.

[0034] Therefore, the front 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.

[0035] Optionally, such as Figure 5 As shown, the first side 101 has a front bumper mounting area 1011. In the front-rear direction, the distance between the spoiler 200 and the rear edge of the front bumper mounting area 1011 is L, where 13mm ≤ L ≤ 23mm. It can be understood that after the front bumper guard is installed, the front bumper mounting area 1011 overlaps with the mounting surface of the front bumper. For example, the front bumper mounting area 1011 and the front bumper can be fixed by snap-fit, riveting, or threaded connection.

[0036] like Figure 5As shown, the rear edge of the front bumper mounting area 1011 is the rear boundary of the front bumper mounting area 1011. The distance L between the spoiler 200 and the rear edge of the front bumper mounting area 1011 can be selected between 13mm and 23mm. By arranging the spoiler 200 in the above manner, the front bumper skid plate of this embodiment can further enhance the spoiler effect of the spoiler 200, thereby increasing the downforce on the front axle of the vehicle without affecting the installation of the components around the front bumper skid plate.

[0037] For example, L can be 13mm, 15mm, 17mm, 18mm, 20mm, or 23mm.

[0038] Optionally, such as Figure 4 As shown, the skid plate body 100 has a third side 103 and a fourth side 104 arranged opposite to each other in the left-right direction. One end of the spoiler 200 extends to the third side 103 in the left-right direction, and the other end of the spoiler 200 extends to the fourth side 104 in the left-right direction. This can increase the spoiler range of the spoiler 200 and increase the downforce coefficient of the vehicle's front axle.

[0039] It is understandable that the dimensions of the spoiler 200 in the left-right direction are roughly equal to the dimensions of the guard plate body 100 in the left-right direction. That is, the spoiler 200 extends to the left and right boundary areas of the guard plate body 100 in the left-right direction to ensure that the spoiler 200 has a large effective area, thereby generating considerable downforce.

[0040] For example, the extension path of the spoiler 200 is generally consistent with the outer contour of the first side 101. The left and right ends of the spoiler 200 gradually extend rearward to adapt to the shape of the first side 101 of the guard plate body 100.

[0041] Optionally, such as Figure 5 As shown, all positions on the lower end face of the spoiler 200 are at the same horizontal height. It can be understood that the distance between each position on the lower end face of the spoiler 200 and the ground is equal. This further enhances the spoiler 200's effect on the airflow field, thereby accelerating local airflow and generating a larger negative pressure in the area where the spoiler 200 is arranged, thus increasing the downforce coefficient of the vehicle's front axle.

[0042] like Figure 3As shown, the maximum protrusion height of the spoiler 200 in the vertical direction is H, where 40mm ≤ H ≤ 50mm. For example, H can be 40mm, 42mm, 44mm, 46mm, 48mm, or 50mm. When H is less than 40mm, the spoiler 200 has a poor effect on airflow and has little impact on the downforce of the vehicle's front axle. When H is greater than 50mm, on the one hand, it limits the ability to increase the downforce of the vehicle's front axle; on the other hand, it causes the lower end of the spoiler 200 to be too close to the ground, making it prone to collisions and shortening the service life of the spoiler 200.

[0043] Therefore, the front bumper guard of this utility model, by designing the protrusion height H of the spoiler 200 in the vertical direction with the above parameters, can not only improve the turbulence effect of the spoiler 200 on the airflow field and significantly increase the downforce in the front axle area of ​​the vehicle, but also reduce the probability of the lower end of the spoiler 200 being bumped due to being too close to the ground.

[0044] In this example of the present invention, the protrusion height of the spoiler 200 gradually decreases along the vertical direction from the middle of the guard plate body 100 to the left and right sides of the guard plate body 100. That is, the protrusion height of the spoiler 200 is gradual, which is beneficial to improving the spoiling effect of the spoiler 200.

[0045] Optionally, such as Figure 2 As shown, the spoiler 200 is detachably connected to the skid plate body 100. Thus, the spoiler 200 and the skid plate body 100 are separate structures, facilitating the manufacturing of the front skid plate. Furthermore, the detachable connection between the spoiler 200 and the skid plate body 100 increases the flexibility of the spoiler 200 during use. When the spoiler 200 is damaged, the operator can remove and replace it individually, reducing subsequent maintenance costs.

[0046] like Figure 2 and Figure 3 As shown, the spoiler 200 includes a horizontal plate 201 and a vertical plate 202 connected together. The thickness direction of the horizontal plate 201 is parallel to the vertical direction of the guard plate body 100, and the thickness direction of the vertical plate 202 is perpendicular to the vertical direction of the guard plate body 100. The horizontal plate 201 is connected to the guard plate body 100, and the vertical plate 202 is located in front of the horizontal plate 201 and protrudes downward. It can be understood that the horizontal plate 201 and the vertical plate 202 are arranged roughly vertically. Since the thickness direction of the horizontal plate 201 is parallel to the vertical direction of the guard plate body 100, it is convenient for the horizontal plate 201 to fit against the lower wall surface of the guard plate body 100. The horizontal plate 201 and the guard plate body 100 can be connected by threaded connection or snap-fit, which makes the installation and disassembly of the spoiler 200 and the guard plate body 100 convenient, and the spoiler 200 is relatively firm after installation.

[0047] Optionally, such as Figure 3 As shown, the spoiler 200 also includes a reinforcing rib 203, which is connected to the lower wall of the horizontal plate 201 and the rear wall of the vertical plate 202. This improves the bending strength of the spoiler 200, thereby reducing the probability of deformation under wind or water loads. Furthermore, since the reinforcing rib 203 is connected to the upper wall of the horizontal plate 201 and the rear wall of the vertical plate 202, its structure can be concealed to maintain the overall appearance of the spoiler 200. Additionally, it prevents the reinforcing rib 203 from negatively impacting airflow, thus enhancing the spoiler's effectiveness.

[0048] For example, such as Figure 3 As shown, the outer periphery of the reinforcing rib 203 is generally triangular to improve the structural strength of the reinforcing rib 203 itself. There can be multiple reinforcing ribs 203, which are arranged at intervals along the extension direction of the spoiler 200 to improve the overall structural strength of the spoiler 200.

[0049] Optionally, such as Figure 3 As shown, the horizontal plate 201 has a connecting hole 2011 that extends through in the vertical direction. The front bottom guard plate also includes a fastener (not shown) that passes through the connecting hole 2011 and the guard plate body 100, thereby improving the reliability of the connection between the horizontal plate 201 and the guard plate body 100. For example, the fastener can be a threaded part or a rivet.

[0050] There are multiple connecting holes 2011, which are arranged at intervals along the extension direction of the horizontal plate 201. Correspondingly, there are multiple fasteners, which are connected to the multiple connecting holes 2011 in a one-to-one correspondence.

[0051] like Figure 6 As shown, the upper wall of the horizontal plate 201 is provided with a locking block 2012, which is engaged with the guard plate body 100. This can improve the stability and reliability of the connection between the turbulence component 200 and the guard plate body 100, and reduce the probability of the turbulence component 200 becoming loose from the guard plate body 100 under wind or water load.

[0052] For example, such as Figure 6 As shown, there are multiple card blocks 2012, which are arranged at intervals along the extending direction of the horizontal plate 201. Accordingly, as... Figure 2 As shown, the protective plate body 100 is provided with multiple locking holes 105, and multiple locking blocks 2012 are locked in one-to-one with the multiple locking holes 105.

[0053] Optionally, such as Figure 3 As shown, a rounded chamfer 2021 is provided at the junction of one side of the vertical plate 202 along its thickness direction and the lower end face of the vertical plate 202. The radius of the rounded chamfer 2021 is R, where 0 < R ≤ 1 mm.

[0054] It is understandable that the radius of the chamfer 2021 needs to be less than 1 mm. For example, the radius R of the chamfer 2021 can be 0.1 mm, 0.2 mm, 0.4 mm, 0.6 mm, 0.8 mm, or 1 mm. The inventors of this application discovered through experimental research that when the chamfer 2021 is greater than 1 mm, there is a decrease in the turbulence effect, which is detrimental to the generation of downforce in the front axle area of ​​the vehicle. Therefore, the radius of the chamfer 2021 is designed to be within 1 mm, which ensures normal processing of the vertical plate 202 while avoiding adverse effects on airflow turbulence.

[0055] In other examples, the junction between the side of the vertical plate 202 along its thickness direction and the lower end face of the vertical plate 202 may not require a chamfer 2021, that is, the side of the vertical plate 202 along its thickness direction and the lower end face of the vertical plate 202 are at right angles.

[0056] Another embodiment of the present invention includes a vehicle body and a front underbody protection plate. The vehicle body includes a front bumper (not shown). The front underbody protection plate is the front underbody protection plate of the present invention. The front underbody protection plate is located on the lower side of the front bumper, and the first side 101 is connected to the front bumper.

[0057] The front 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.
