Description

Technical Field

[0001] This application relates to the field of rear vehicle body technology, specifically to a rear skid plate bracket and a vehicle. Background Technology

[0002] Currently, the rear of vehicles typically uses a chassis piping cover bracket (referred to as the rear cover bracket) to connect the rear floor to the rear chassis piping cover (referred to as the rear chassis cover). However, due to the poor design of the water-facing side of the existing bracket structure, when the vehicle passes through a flooded section of road at high speed, water flow will directly impact the rear bumper and rear chassis cover, which can easily lead to component damage, affecting driving safety and component lifespan. Utility Model Content

[0003] In view of the above problems, this application provides a rear skid plate bracket and vehicle that can almost prevent water flow from bypassing the rear of the rear skid plate bracket and directly impacting the more vulnerable rear chassis skid plate and rear bumper.

[0004] According to one aspect of the embodiments of this application, a rear skid plate bracket is provided. The rear skid plate bracket is connected between the rear floor and the rear chassis skid plate. The rear skid plate bracket includes a front baffle and a bracket body. The front baffle and the bracket body are arranged opposite to each other along the width direction of the rear skid plate bracket and are connected to each other. The front baffle is provided with a water-blocking surface. The water-blocking surface includes a right wing surface, a main water-blocking surface, and a left wing surface arranged sequentially along the length direction of the rear skid plate bracket. One end of the right wing surface and the left wing surface are connected to the main water-blocking surface, and the other end of each extends away from the bracket body.

[0005] In one optional exemplary embodiment, the right wing surface includes a first right-sloping surface and a second right-sloping surface, the first right-sloping surface being connected between the main water-blocking surface and the second right-sloping surface, the angle between the first right-sloping surface and the main water-blocking surface being an obtuse angle and greater than the angle between the first right-sloping surface and the second right-sloping surface; the left wing surface includes a first left-sloping surface and a second left-sloping surface, the first left-sloping surface being connected between the main water-blocking surface and the second left-sloping surface, the angle between the first left-sloping surface and the main water-blocking surface being an obtuse angle and greater than the angle between the first left-sloping surface and the second left-sloping surface.

[0006] In an optional exemplary embodiment, the front baffle includes a water-blocking portion and a flanged portion, the water-blocking surface is located in the water-blocking portion, the flanged portion includes a flanged bottom surface and a flanged top surface disposed opposite to each other along the height direction of the rear guard plate bracket, the flanged bottom surface is used to connect with the rear floor, and the flanged top surface intersects with the water-blocking surface; the rear guard plate bracket further includes a first reinforcing rib, the first reinforcing rib connecting the flanged bottom surface and the water-blocking surface.

[0007] In one optional exemplary embodiment, the first reinforcing rib has a triangular structure, and the two sides of the first reinforcing rib are connected one-to-one to the bottom surface of the flange and the water-blocking surface.

[0008] In one optional exemplary embodiment, the water-blocking part includes a right wing plate, a middle water-blocking plate, and a left wing plate, wherein the right wing surface is located on the right wing plate, the main water-blocking surface is located on the middle water-blocking plate, and the left wing surface is located on the left wing plate; wherein the height of the middle water-blocking plate is greater than the height of the right wing plate and greater than the height of the left wing plate.

[0009] In an optional exemplary embodiment, the main body of the bracket includes a rear baffle and a supporting top plate. The rear baffle and the front baffle are disposed opposite to each other along the width direction of the rear guard plate bracket. The supporting top plate is connected between the rear baffle and the front baffle, and together with the rear baffle and the front baffle, they form a "U"-shaped structure.

[0010] In one optional exemplary embodiment, the support top plate is provided with a drainage hole that extends through the support top plate along the height direction of the rear guard plate bracket.

[0011] In one optional exemplary embodiment, the rear baffle is provided with a weight-reducing hole that extends through the rear baffle along the width direction of the rear guard plate bracket.

[0012] In one optional exemplary embodiment, the rear guard plate bracket further includes a second reinforcing rib, which is connected to the rear baffle and arranged around the weight reduction hole.

[0013] According to another aspect of the embodiments of this application, a vehicle is provided, including a rear floor, a rear chassis guard plate, and the aforementioned rear guard plate bracket, wherein the rear guard plate bracket is connected between the rear floor and the rear chassis guard plate.

[0014] In this application, after the rear skid plate bracket is connected between the rear floor and the rear chassis skid plate, if the vehicle encounters water, the water flow will most likely first impact the main water-retaining surface of the front skid plate. At this time, since one end of the left and right wings are both connected to the main water-retaining surface, and the other end extends away from the main body of the bracket, making the overall water-retaining surface approximately "U" shaped, the water flow will be guided to both sides of the vehicle's wheel track direction by the action of the left and right wings, almost preventing the water flow from bypassing the rear skid plate bracket and directly impacting the more vulnerable rear chassis skid plate and rear bumper.

[0027] Combination Figures 1 to 3 As shown, this embodiment provides a vehicle and a rear skid plate bracket a. The vehicle includes a rear floor b, a rear chassis skid plate c, a rear bumper assembly d, and the rear skid plate bracket a. The rear skid plate bracket a is connected between the rear floor b and the rear chassis skid plate c.

[0028] It should be understood that the rear chassis skid plate c is also called the rear chassis piping skid plate. The rear chassis skid plate c and the rear floor b are spaced apart along the vehicle's height direction h. The rear bumper assembly d is positioned around the rear, left, and right sides of the rear chassis skid plate c and the rear floor b, forming a cavity between them. The rear skid plate bracket a connects the rear chassis skid plate c to the rear floor b and prevents water from entering the cavity and impacting the rear chassis skid plate c and the rear bumper assembly d.

[0029] Combination Figure 5 As shown, the rear guard plate bracket a includes a front baffle 10 and a bracket body (including a rear baffle 20 and a supporting top plate 30 in the figure). The front baffle 10 and the bracket body are arranged opposite to each other along the width direction w of the rear guard plate bracket a and are connected to each other.

[0030] It should be understood that after the rear skid plate bracket a connects the rear chassis skid plate c and the rear floor b, the width direction w of the rear skid plate bracket a is the wheelbase direction of the vehicle, the length direction l of the rear skid plate bracket a is the track direction of the vehicle, and the height direction h of the rear skid plate bracket a is the height direction h of the vehicle. The front slicker-to-the-front section 10 is closer to the front of the vehicle than the main body of the bracket, in order to block water flow towards the side of the main body of the bracket.

[0031] Furthermore, combined Figure 4 As shown, the front baffle 10 is provided with a water-blocking surface 10a. The water-blocking surface 10a includes a right wing surface 111a, a main water-blocking surface 112a and a left wing surface 113a arranged sequentially along the length direction l of the rear guard plate bracket a. One end of the right wing surface 111a and the left wing surface 113a are connected to the main water-blocking surface 112a, and the other end of each extends away from the main body of the bracket.

[0032] For example, one end of the right wing surface 111a and the left wing surface 113a are connected to the main water-blocking surface 112a, and the other end of both are extended away from the main body of the support, so that the water-blocking surface 10a is approximately "U" shaped.

[0033] In this invention, after the rear skid plate bracket a is connected between the rear floor b and the rear chassis skid plate c, if the vehicle encounters water, the water flow will most likely first impact the main water-blocking surface 112a of the front water deflector 10. At this time, since one end of the left wing surface 113a and the right wing surface 111a are both connected to the main water-blocking surface 112a, and the other end is extended away from the main body of the bracket, the water-blocking surface 10a is approximately "U" shaped. Therefore, under the action of the left wing surface 113a and the right wing surface 111a, the water flow will be guided to both sides of the vehicle's wheel track direction, almost preventing the water flow from directly bypassing the rear skid plate bracket a and impacting the more vulnerable rear chassis skid plate c and rear bumper.

[0034] Furthermore, the right wing surface 111a includes a first right-sloping surface and a second right-sloping surface. The first right-sloping surface is connected between the main water-blocking surface 112a and the second right-sloping surface. The angle between the first right-sloping surface and the main water-blocking surface 112a is an obtuse angle α1, which is greater than the angle α2 between the first right-sloping surface and the second right-sloping surface. The left wing surface 113a includes a first left-sloping surface and a second left-sloping surface. The first left-sloping surface is connected between the main water-blocking surface 112a and the second left-sloping surface. The angle between the first left-sloping surface and the main water-blocking surface 112a is an obtuse angle β1, which is greater than the angle β2 between the first left-sloping surface and the second left-sloping surface.

[0035] Optionally, both α2 and β2 are greater than 90° and less than 180°.

[0036] It should be understood that after the water flow impacts the main water-blocking surface 112a, it first encounters the first right-sloping surface and the first left-sloping surface, which gently guide the water flow to both sides of the vehicle. Subsequently, the water flow is further accelerated and guided to the outside along the second right-sloping surface and the second left-sloping surface with smaller angles. This "slow first, then fast" guiding method can more smoothly guide the water to both sides of the vehicle, reduce the impact and resistance of the water on the rear guard plate bracket a, and prevent the front water-blocking plate 10 of the rear guard plate bracket a from being deformed or damaged.

[0037] Combination Figure 4 As shown, the front baffle 10 includes a water-blocking part 11 and a flanged part 12. The water-blocking surface 10a is located in the water-blocking part 11. The flanged part 12 includes a flanged bottom surface and a flanged top surface that are disposed opposite to each other along the height direction h of the rear guard plate bracket a. The flanged bottom surface is used to connect with the rear floor b, and the flanged top surface intersects with the water-blocking surface 10a. The rear guard plate bracket a also includes a first reinforcing rib 13, which connects the flanged bottom surface and the water-blocking surface 10a.

[0038] It should be understood that the flange 12 provides a stable mounting surface for the rear guard plate bracket a and the rear floor b, while the first reinforcing rib 13 connects the bottom surface of the flange and the water-retaining surface 10a, enabling a solid support to be established between the water-retaining surface 10a and the bottom surface of the flange.

[0039] In this embodiment, the first reinforcing rib 13 has a triangular structure, and its two sides are connected to the bottom surface of the flange and the water-blocking surface 10a respectively. Specifically, the first reinforcing rib 13 is a triangular plate structure. After the two sides of the first reinforcing rib 13 are connected to the bottom surface of the flange and the water-blocking surface 10a respectively, the main plate surface of the first reinforcing rib 13 is perpendicular to the bottom surface of the flange and the water-blocking surface 10a.

[0040] For example, there are a total of 9 first reinforcing ribs 13, and the 9 first reinforcing ribs 13 are arranged at intervals along the length direction l of the rear guard plate bracket a.

[0041] It should be understood that, since the triangle is the most stable geometric structure, it can most effectively disperse and transfer the impact force on the water-retaining surface 10a to the flange 12 and the rear floor b, avoiding fatigue fracture caused by stress concentration. Therefore, when the water-retaining surface 10a is impacted by water flow, and the impact force attempts to bend the water-retaining surface 10a relative to the flange 12, the first reinforcing rib 13 of the triangle can act as a support rod, thereby resisting this bending tendency and ensuring that the entire front water-retaining plate 10 bears the load as a whole.

[0042] Combination Figure 4As shown, the water blocking portion 11 includes a right wing plate 111, a middle water blocking plate 112 and a left wing plate 113, the right wing surface 111a is located on the right wing plate 111, the main water blocking surface 112a is located on the middle water blocking plate 112, and the left wing surface 113a is located on the left wing plate 113; wherein the height of the middle water blocking plate 112 is greater than the height of the right wing plate 111, and is also greater than the height of the left wing plate 113.

[0043] It should be understood that the middle water blocking plate 112 is used to block the main water flow from the front, and the right wing plate 111 and the left wing plate 113 mainly play the roles of guiding and containing, preventing the water flow from detouring from the sides. Meanwhile, since the heights of the right wing plate 111 and the left wing plate 113 are lower than that of the middle water blocking plate 112, unnecessary materials and weight can be reduced to achieve lightweight design.

[0044] With reference to Figure 5 and Figure 6 as shown, the bracket main body portion includes a rear water blocking plate 20 and a supporting top plate 30. The rear water blocking plate 20 and the front water blocking plate 10 are disposed opposite to each other along the width direction w of the rear fender bracket a. The supporting top plate 30 is connected between the rear water blocking plate 20 and the front water blocking plate 10, and together with the rear water blocking plate 20 and the front water blocking plate 10 forms a "several"-shaped structure.

[0045] It should be understood that the "several"-shaped structure jointly formed by the supporting top plate 30, the rear water blocking plate 20 and the front water blocking plate 10 is not a strictly defined "several"-shaped structure, and it is only required that the cross section of the outer contour of the rear fender bracket a is approximately "several"-shaped. Wherein, since the "several"-shaped cross section is a structure with relatively high rigidity, after the supporting top plate 30, the rear water blocking plate 20 and the front water blocking plate 10 jointly form the "several"-shaped structure, the rear fender bracket a can be changed from a simple connecting plate to a box girder structure with extremely strong bending resistance and torsion resistance.

[0046] With reference to Figure 5 as shown, the supporting top plate 30 is provided with water leakage holes 101. The water leakage holes 101 penetrate through the supporting top plate 30 along the height direction h of the rear fender bracket a, so as to allow a small amount of water to cross the front water blocking plate 10 and flow into the rear fender bracket a from the water leakage holes 101, thereby reducing the direct impact of water on the rear bumper assembly d.

[0047] For example, three water leakage holes 101 are provided on the supporting top plate 30, and the three water leakage holes 101 are arranged at intervals along the length direction l of the rear fender bracket a.

[0048] With reference to Figure 5 as shown, the rear water blocking plate 20 is provided with lightening holes 102. The lightening holes 102 penetrate through the rear water blocking plate 20 along the width direction w of the rear fender bracket a, so as to remove excess materials and achieve lightweight design of the rear fender bracket a.

[0049] For example, the rear baffle 20 is provided with two weight reduction holes 102, which are spaced apart from each other.

[0050] Combination Figure 5 As shown, the rear guard plate bracket a also includes a second reinforcing rib 14, which is connected to the rear baffle 20 to compensate for the potential reduction in rigidity caused by the weight reduction hole 102.

[0051] Combination Figure 5 As shown, the second reinforcing rib 14 is arranged around the weight reduction hole 102 to form a "reinforcing frame", which ensures the local stiffness of the opening area and prevents it from becoming a new structural weak point or noise source.

[0052] In summary, the rear skid plate bracket a of this utility model, through the structure of the main water-blocking surface 112a of the front baffle 10 plus the left wing surface 113a and the right wing surface 111a, provides a large water-facing area, achieving active water blocking and dispersing the water flow to both sides of the vehicle. Simultaneously, the design of the first and second left inclined surfaces of the left wing surface 113a and the first and second right inclined surfaces of the right wing surface 111a smoothly and efficiently guides the water flow to both sides of the vehicle, greatly reducing water flow resistance and splashing. Furthermore, the "U"-shaped cross-section structure of the rear skid plate bracket a provides extremely strong bending and torsional rigidity, and the combination of the flanged portion 12 and the triangular first reinforcing rib 13 ensures the robustness and reliability of the connection point (force-bearing root) between the rear skid plate bracket a and the rear chassis skid plate c, preventing deformation of the front baffle 10 due to water impact.
