Abstract
Description
Technical Field
[0001] This application relates to the field of vehicle technology, and in particular to a bottom guard plate for a vehicle and the vehicle itself. Background Technology
[0002] Underbody protection panels are components used to cover chassis parts and enhance the aesthetics of the undercarriage. They typically face the road directly and primarily protect the vehicle's chassis components and related accessories during driving, preventing damage from road debris, flying stones, uneven surfaces, and scraping. Through their excellent stability and resistance to weathering, underbody protection panels effectively protect and reduce corrosion and impact on chassis components and related accessories.
[0003] The inventors of this application have discovered that, in actual use, there is a risk that the bottom guard plate may tear due to vibration of the chassis components. Utility Model Content
[0004] This application provides a bottom guard plate for a vehicle and a vehicle, which can increase the strength of the bottom guard plate.
[0005] The first aspect of this application provides a bottom guard plate for a vehicle, the bottom guard plate having a first plate surface and a second plate surface disposed opposite to each other, the first plate surface having at least one first buffer recess protruding toward the second plate surface, at least a portion of the first buffer recess extending in a first direction, the first direction being the width direction of the vehicle.
[0006] The second plate surface is provided with at least one second buffer recess protruding toward the first plate surface, and at least a portion of the second buffer recess extends in the first direction.
[0007] The number of the first buffer recesses is multiple, and the multiple first buffer recesses are spaced apart in a second direction, which is the length direction of the vehicle.
[0008] The plurality of buffer protrusions constitute a plurality of repeating units, and the plurality of repeating units are spaced apart in the second direction, wherein the distance between two adjacent repeating units is greater than the distance between two adjacent first buffer recesses in the repeating unit.
[0009] The first buffer recess is an arc-shaped recess, a sawtooth recess, or a rectangular recess.
[0010] The bottom guard plate includes a first side and a second side spaced apart in the first direction, and the first buffer recess extends from the first side to the second side.
[0011] Wherein, the first buffer recess extends in a straight line, or the middle section of the first buffer recess extends in a straight line, and the two ends of the first buffer recess extend away from the middle section in the first direction.
[0012] The bottom protective plate is manufactured using a molding process.
[0013] The bottom protective plate is made of glass fiber and polypropylene.
[0014] A second aspect of this application provides a vehicle including any of the aforementioned underbody protection plates for vehicles.
[0015] The beneficial effects are as follows: In related technologies, since the bottom guard plate is connected to the chassis components, the vehicle will wade through water and the chassis components will vibrate and shake during vehicle operation. This vibration and shaking, as well as the vehicle wading through water, will cause the bottom guard plate to wear and soften, thus creating the problem and risk of the bottom guard plate tearing and detaching. However, this application provides a first buffer recess on the bottom guard plate, and at least part of the first buffer recess extends along the width direction of the vehicle, which can reduce the kinetic energy radiated along the length direction of the vehicle. That is, the first buffer recess can play a buffering role, which can reduce the adverse effects caused by the vibration of the bottom guard plate, thereby increasing the strength of the bottom guard plate.

[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.
[0024] It should be noted that the terms "first" and "second" in this application are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products, or apparatuses.
[0025] See Figure 1 as well as Figure 2 In one embodiment, the underbody guard plate 100 of the present application for a vehicle has a first plate surface 110 and a second plate surface 120 disposed opposite to each other. The first plate surface 110 has at least one first buffer recess 130 protruding toward the second plate surface 120. At least a portion of the first buffer recess 130 extends in a first direction X, where the first direction X is the width direction of the vehicle.
[0026] Specifically, the underbody protection plate 100 is a component used to cover chassis components and increase the aesthetics of the underbody. It is connected to the chassis components. During vehicle operation, the vehicle may wade through water, and the chassis components may vibrate and shake. This vibration and water wading can cause wear and tear on the underbody protection plate 100, weakening its strength and creating a risk of tearing and detachment. However, this application provides a first buffer recess 130 on the first surface 110 of the underbody protection plate 100. The first buffer recess 130 is recessed on the first surface 110 and protrudes on the second surface 120. Furthermore, the first buffer recess 130 extends at least partially along the first direction X. Therefore, it can reduce the kinetic energy radiated along the length of the vehicle, thereby reducing the vibration of the underbody protection plate 100 and providing a buffering effect. Thus, the provision of the first buffer recess 130 in this application can reduce tearing of the underbody protection plate 100 due to vibration, thereby increasing the strength of the underbody protection plate 100.
[0027] As can be seen from the above, the first buffer recess 130 of this application can meet the NVH performance requirements of the whole vehicle and enhance the strength of the bottom guard plate 100 under the same material and manufacturing process.
[0028] The first buffer recess 130 may extend only partially in the first direction X, or it may extend entirely in the first direction X.
[0029] The width (width direction is the length direction of the vehicle) and length (length direction is the width direction of the vehicle) of the first buffer recess 130 can be set according to actual needs.
[0030] In one embodiment, the bottom guard plate 100 is manufactured using a molding process. This design ensures the strength of the bottom guard plate 100 and improves its manufacturing efficiency. Specifically, when manufacturing the bottom guard plate 100 using a molding process, the product thickness is reduced from, for example, 15 mm to, for example, 3 mm. This results in a layered internal structure for the bottom guard plate 100. Vibrations from prolonged vehicle driving and water wading can weaken the bottom guard plate 100. The first buffer recess 130 in this application prevents the bottom guard plate 100 from softening. It should be noted that in other embodiments, the bottom guard plate 100 can also be manufactured using a particle injection molding process. This application does not limit the processing technology of the bottom guard plate 100.
[0031] See Figure 3In one embodiment, the second plate surface 120 is provided with at least one second buffer recess 140 protruding toward the first plate surface 110. At least a portion of the second buffer recess 140 extends in the first direction X, that is, the second buffer recess 140 is recessed on the second plate surface 120 and protrudes on the first plate surface 110. Similar to the function of the first buffer recess 130, the second buffer recess 140 can also reduce the kinetic energy radiated along the length direction of the vehicle, thereby reducing the vibration of the bottom guard plate 100 and playing a buffering role. Therefore, the provision of the second buffer recess 140 can further improve the strength of the bottom guard plate 100.
[0032] Similar to the first buffer recess 130, the second buffer recess 140 may extend only partially in the first direction X, or it may extend entirely in the first direction X.
[0033] See Figure 3 In one embodiment, in the second direction Y, the second buffer recess 140 is disposed between two adjacent first buffer recesses 130.
[0034] In another embodiment, in the second direction Y, the first buffer recess 130 and the second buffer recess 140 are alternately arranged.
[0035] The number of first buffer recesses 130 can be one or more. (Continue reading...) Figure 1 In one embodiment, there are multiple first buffer recesses 130, which are spaced apart in a second direction Y, where Y is the length direction of the vehicle. It is understood that compared to having only one first buffer recess 130, multiple first buffer recesses 130 provide stronger buffering and can further enhance the strength of the bottom guard plate 100.
[0036] The number of second buffer recesses 140 can be one or more.
[0037] See Figure 1 In one embodiment, when there are multiple first buffer recesses 130, the multiple first buffer recesses 130 constitute multiple repeating units 10. The multiple repeating units 10 are spaced apart in the second direction Y, wherein the distance between two adjacent repeating units 10 is greater than the distance between two adjacent first buffer recesses 130 in the repeating unit 10. The number of first buffer recesses 130 in the repeating unit 10 can be two, three, or more. Figure 1 The repeating unit 10 is illustrated by including two first buffer recesses 130. The spacing between two adjacent first buffer recesses 130 in the repeating unit 10 is small, while the spacing between two adjacent repeating units 10 is large.
[0038] In one embodiment, the plurality of first buffer recesses 130 in the repeating unit 10 have the same structure. The identical structure of the first buffer recesses 130 means that parameters such as shape and width (the width direction of the first buffer recess 130 is the second direction Y) are the same. For example, Figure 1 The embodiment illustrates two repeating units 10. For ease of explanation, these two repeating units 10 are defined as a first repeating unit 11 and a second repeating unit 12, respectively. The two first buffer recesses 130 included in the first repeating unit 11 have identical structures, and the two first buffer recesses 130 included in the second repeating unit 12 have identical structures. However, the structures of the first buffer recesses 130 in the first repeating unit 11 and the first buffer recesses 130 in the second repeating unit 12 are different. It should be noted, however, that in other embodiments, the structures of the first buffer recesses 130 in the same repeating unit 10 may be different, and the structures of the first buffer recesses 130 in different repeating units 10 may be identical; this application does not impose any limitations.
[0039] The spacing between two adjacent repeating units 10 and the spacing between two adjacent first buffer recesses 130 in the repeating unit 10 can be set according to actual needs, and this application does not impose any restrictions on this.
[0040] It should be noted that in other embodiments, when there are multiple first buffer recesses 130, the multiple first buffer recesses 130 can be equally spaced in the second direction Y.
[0041] In one embodiment, the first buffer recess 130 is an arc-shaped recess (e.g., Figure 1 as well as Figure 3 As shown, the cross-section of the first buffer recess 130 is arc-shaped, and the serrated recess (such as...) Figure 4 As shown, the cross-section of the first buffer recess 130 is serrated) or a rectangular recess (such as... Figure 5 As shown, the cross-section of the first buffer recess 130 is rectangular. This application does not limit the shape of the first buffer recess 130. For example, in other embodiments, the first buffer recess 130 may also be a trapezoidal recess, meaning the cross-section of the first buffer recess 130 is trapezoidal.
[0042] The second buffer recess 140 can also be an arc-shaped recess, a sawtooth recess, or a rectangular recess. The cross-sectional shapes of the first buffer recess 130 and the second buffer recess 140 can be the same or different, for example, in... Figure 3 In the implementation, both the first buffer recess 130 and the second buffer recess 140 are arc-shaped recesses.
[0043] When there are multiple first buffer recesses 130, the cross-sections of the multiple first buffer recesses 130 can be the same or different. For example, in Figure 6 In the implementation, when there are multiple first buffer recesses 130, some of the first buffer recesses 130 are arc-shaped recesses, and some of the first buffer recesses 130 are sawtooth recesses.
[0044] See Figure 1 In one embodiment, the bottom guard plate 100 includes a first side 101 and a second side 102 spaced apart in a first direction X, and a first buffer recess 130 extends from the first side 101 to the second side 102. This arrangement allows the first buffer recess 130 to connect the first side 101 and the second side 102, increasing the length of the first buffer recess 130, further reducing the kinetic energy radiated along the length direction of the vehicle, and further improving the buffering effect of the first buffer recess 130. However, it should be noted that in other embodiments, the first buffer recess 130 may not be connected to the first side 101 and the second side 102. For example, one end of the first buffer recess 130 is connected to the first side 101, and the other end is at a preset distance from the second side 102. Alternatively, one end of the first buffer recess 130 is at a preset distance from the first side 101, and the second end is connected to the second side 102. Or, one end of the first buffer recess 130 is at a preset distance from the first side 101, and the other end is at a preset distance from the second side 102.
[0045] See Figure 1 In one embodiment, the first buffer recess 130 extends in a straight line. For example, in Figure 1 In the implementation, the first buffer recess 130 in the first repeating unit 11 extends in a straight line.
[0046] See Figure 1 In one embodiment, the middle section of the first buffer recess 130 extends in a straight line, and both ends of the first buffer recess 130 extend away from the middle section in the first direction X. For example, in Figure 1 In this embodiment, the middle section of the first buffer recess 130 in the second repeating unit 12 extends in a straight line, and both ends of the first buffer recess 130 extend away from the middle section in the first direction X. This arrangement can increase the length of the first buffer recess 130, further improve its buffering effect, and increase the strength of the bottom guard plate 100.
[0047] It should be noted that in other embodiments, the first buffer recess 130 may also extend in a serpentine shape. In summary, this application does not limit the extension shape of the first buffer recess 130.
[0048] In one embodiment, the bottom guard plate 100 is made of glass fiber (GF) and polypropylene (PP), thereby combining the excellent properties of the PP matrix and glass fiber, resulting in advantages such as high strength, high rigidity, excellent heat resistance, and good moldability. In a specific example, the bottom guard plate 100 is made of PP-GF30, i.e., 30% glass fiber reinforced polypropylene. In other embodiments, the bottom guard plate 100 may also be made of other materials such as PP-GF10 and PP-GF20. This application does not limit the specific material of the bottom guard plate 100.
[0049] In one embodiment, the thickness of the bottom guard plate 100 ranges from 1 mm to 10 mm, for example, the thickness of the bottom guard plate 100 is 1 mm, 3 mm, 5 mm, 8 mm or 10 mm.
[0050] In addition, this application also protects a vehicle that includes the underbody protection plate 100 in any of the above embodiments. For details on the specific structure of the underbody protection plate 100, please refer to the above-mentioned related content, which will not be repeated here.
[0051] Since the bottom guard plate 100 of this application is provided with a first buffer recess 130, which extends at least partially along the width direction of the vehicle, it can reduce the kinetic energy radiated along the length direction of the vehicle, thereby reducing the vibration of the bottom guard plate 100 and reducing the tearing of the bottom guard plate 100 caused by vibration, thereby increasing the strength of the bottom guard plate 100 and ensuring the quality of the vehicle.
[0052] The above description is merely an embodiment of this application and does not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
