DETAILED DESCRIPTION

[0033] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this application will be more comprehensive and complete and fully convey the concept of the example embodiments to those skilled in the art.

In the following description, many specific details are provided to provide a full understanding of the embodiments of the present application. However, those skilled in the art will appreciate that the technical scheme of the present application can be put into practice without one or more of the specific details, or other methods, components, devices, steps, etc. can be adopted. In other cases, known methods, devices, realizations or operations are not shown or described in detail to avoid blurring the various aspects of the application.

[0035] The present application is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the technical features involved in the various embodiments of the present application described below can be combined with each other as long as they do not conflict with each other. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be understood as limiting the present application.

[0036] like Figures 1 to 13As shown, this embodiment provides a bottom guard plate structure of a vehicle, including: a bottom guard plate 1 and a guide structure 2, the bottom guard plate 1 is provided with an opening 101, and the opening 101 passes through the bottom guard plate 1; the guide structure 2 is located in the opening 101, and the guide structure 2 is connected to the bottom guard plate 1; the guide structure 2 includes at least one grille blade 21, and the grille blade 21 is obliquely arranged in the opening 101 and connected to the bottom guard plate 1.

[0037] In this embodiment, when the bottom guard plate structure is installed on the vehicle, the axial direction of the opening 101 is perpendicular to the horizontal plane. The grille blade 21 is tilted in the opening 101, which means that after the grille blade 21 is located in the opening 101, the plate surface of the grille blade 21 forms an acute angle or an obtuse angle with the axial direction or the radial direction of the opening 101, that is, when the bottom guard plate structure is installed on the vehicle, the grille blade 21 forms an acute angle or an obtuse angle with the horizontal plane.

[0038] In this embodiment, the bottom guard plate 1 is provided with an opening 101, and the opening 101 passes through the bottom guard plate 1, so that the hot air flow in the cabin can be discharged through the opening 101 of the bottom guard plate 1, so as to reduce the temperature of the cabin and prevent the components with low heat resistance in the cabin from failing to work normally or being damaged due to excessive temperature; further, a guide structure 2 is provided in the opening 101, and the guide structure 2 includes at least one grille blade 21, and the grille blade 21 is inclined relative to the opening 101. The grille blade 21 can not only guide the hot air flow in the cabin, facilitating the outflow of the hot air flow in the cabin, but also block part of the air flow outside the cabin from entering the cabin, which is beneficial to reducing the wind resistance of the whole vehicle, thereby improving the vehicle's endurance.

[0039] For example, since the grille blades 21 are tilted in the openings 101, when the bottom guard plate structure is installed on the vehicle, the end of the grille blades 21 close to the ground tilts toward the rear of the vehicle, which can facilitate the discharge of hot air in the cabin and block part of the air outside the cabin from entering the cabin.

[0040] It should be understood that after the grille blade 21 is disposed in the opening 101 , the end of the grille blade 21 close to the ground refers to the end surface where the gap between the grille blade 21 and the ground is the smallest.

[0041] Combination Figure 4 As shown, the grille blade 21 includes an upper blade section 211 and a lower blade section 212 , and the included angle between the upper blade section 211 and the lower blade section 212 is an obtuse angle.

[0042] In this embodiment, the upper blade section 211 is closer to the vehicle's engine room than the lower blade section 212. An obtuse angle is formed between the upper blade section 211 and the lower blade section 212, which can effectively increase the outflow of hot air in the engine room along the grille blade 21 from the opening 101, thereby reducing the temperature of the engine room more quickly and preventing components in the engine room from malfunctioning or being damaged due to excessive temperature.

[0043] Combination Figure 4 As shown, the upper blade section 211 and the lower blade section 212 are both inclinedly disposed in the opening 101 .

[0044] In this embodiment, the upper blade section 211 and the lower blade section 212 form an acute angle with the axial direction of the opening 101 and the radial direction of the opening 101, which is beneficial for the hot air flow in the cabin to flow out in the same flow direction as outside the cabin, and can also block part of the air flow outside the cabin from entering the cabin, ensuring that the hot air flow in the cabin can flow out from the opening 101, ultimately achieving the purpose of reducing the air resistance of the entire vehicle.

[0045] Combination Figure 4 As shown, the lower blade section 212 includes a top end a and a bottom end b that are relatively arranged. The top end a of the lower blade section 212 is connected to the upper blade section 211, and the thickness of the lower blade section 212 gradually increases from the top end a of the lower blade section 212 toward the bottom end b of the lower blade section 212.

[0046] In this embodiment, the lower blade section 212 includes a first surface c and a second surface. The first surface c is closer to the vehicle's cabin than the second surface. The distance between the first surface c and the second surface gradually increases from the top end a of the lower blade section 212 toward the bottom end b of the lower blade section 212, guiding the airflow flowing through the bottom of the vehicle from the front to the rear, so that the airflow outside the cabin does not flow into the cabin, ensuring that the hot air flow in the cabin can flow out from the opening 101, which is beneficial to improving the wind resistance performance of the entire vehicle.

[0047] It should be understood that the thickness of the blade lower section 212 is the distance between the first surface c and the second surface.

[0048] Specifically, the angle between the second surface and the horizontal plane is 157°-166°.

[0049] Combination Figure 3 and Figure 4 As shown, the air guide structure 2 includes a plurality of grille vanes 21 , and the plurality of grille vanes 21 are arranged at intervals from each other along the axial direction of the vehicle.

[0050] In this embodiment, the intervals between two adjacent grille blades 21 are the same, and the multiple grille blades 21 can evenly guide the hot air flow in the cabin to the outside of the cabin, thereby reducing the cabin temperature more quickly and preventing cabin components from failing to work or being damaged due to excessive temperature. At the same time, the multiple grille blades 21 also have a certain guiding effect on the hot air flow in the cabin, so that the outflow direction of the hot air flow in the cabin through the opening 101 has a certain probability of being consistent with the direction of the air flow flowing through the bottom of the vehicle, thereby reducing the wind resistance of the entire vehicle and improving the vehicle's cruising range.

[0051] In this embodiment, the upper blade section 211 also includes a top end a and a bottom end b that are relatively arranged. The bottom end b of the upper blade section 211 is connected to the top end a of the lower blade section 212. Therefore, the distance between the bottom end b of the lower blade section 212 and the top end a of the upper blade section 211 along the axial direction of the vehicle is the gap between two adjacent grille blades 21.

[0052] Specifically, the gap between two adjacent grille blades 21 ranges from 4.2 mm to 5.2 mm.

[0053] In this embodiment, combined with Figure 4 As shown, two adjacent grille blades 21 are parallel to each other, so that the hot air flow in the cabin flows out from the opening 101 through the grille blades 21 in the same direction, reducing the probability of wind resistance generated by the hot air flow in the cabin due to different outflow directions, which is beneficial to improving the vehicle's endurance.

[0054] It should be understood that two adjacent grille blades 21 are parallel to each other, which requires that while the upper blade sections 211 of the two adjacent grille blades 21 are parallel to each other, the lower blade sections 212 of the two adjacent grille blades 21 are also parallel to each other.

[0055] Combination Figures 1 to 4 As shown, the bottom guard plate 1 is provided with a plurality of openings 101 , and the bottom guard plate structure includes a plurality of flow guiding structures 2 , and the plurality of flow guiding structures 2 are arranged in the plurality of openings 101 in a one-to-one correspondence.

[0056] In this embodiment, the bottom guard plate 1 is provided with a plurality of openings 101, and the number of the openings 101 of the bottom guard plate 1 is increased to increase the area of ​​the openings 101 of the bottom guard plate 1, so that the hot air flow in the cabin can be discharged quickly, which is beneficial to increasing the discharge speed of the hot air flow in the cabin and reducing the cabin temperature; at the same time, the plurality of guide structures 2 are inclinedly arranged in the plurality of openings 101 one by one, and the guide structures 2 in the openings 101 have a certain guiding effect on the hot air flow in the cabin, so that the hot air flow discharged from the cabin has a certain probability of being consistent with the flow direction of the air flow outside the cabin, so as to reduce the wind resistance of the whole vehicle and improve the vehicle's endurance.

[0057] The present embodiment also provides a vehicle, including a battery pack 3 and the bottom guard plate structure of the above-mentioned vehicle, the bottom guard plate 1 includes a first bottom plate portion 11, a second bottom plate portion 12 and a third bottom plate portion 13, the first bottom plate portion 11 is located between the second bottom plate portion 12 and the third bottom plate portion 13, and the battery pack 3 is located on the side of the second bottom plate portion 12 away from the first bottom plate portion 11; the second bottom plate portion 12 and the third bottom plate portion 13 are both provided with an opening 101, and a guide structure 2 is correspondingly provided in the opening 101.

[0058] In this embodiment, the second bottom plate portion 12 and the third bottom plate portion 13 are both provided with openings 101, and a guide structure 2 is correspondingly provided in the openings 101, so that the hot air flow in the cabin is roughly consistent with the flow direction of the air flow at the bottom of the vehicle after it flows out, reducing the wind resistance of the whole vehicle, thereby increasing the cruising range of the battery pack 3. The guide structure 2 is provided in the openings 101, which is conducive to reducing the energy loss of the battery pack 3. Compared with only providing the openings 101, the wind resistance coefficient of the whole vehicle is reduced by about 2-3 counts, and the cruising range of the battery pack 3 is increased by about 1.5 km. According to the cruising range, the battery cost can be saved by 100-200 yuan.

[0059] In this embodiment, combined with Figures 5 to 7 As shown, the second bottom plate portion 12 is provided with a first opening 101a, the third bottom plate portion 13 is provided with a second opening 101b, and the grille vanes 21 located in the first opening 101a are different from the grille vanes 21 located in the second opening 101b.

[0060] Specifically, the length of the first opening 101a is 220mm-230mm, and the width of the first opening 101a is 155mm-165mm; the length of the upper blade section 211 of the grille blade 21 located in the first opening 101a is 8mm-8.5mm, the length of the lower blade section 212 of the grille blade 21 located in the first opening 101a is 10mm-10.5mm, and the angle between the upper blade section 211 and the lower blade section 212 of the grille blade 21 located in the first opening 101a is 155°-160°; the angle between the second surface of the lower blade section 212 of the grille blade 21 located in the first opening 101a and the horizontal plane is 169°-177°.

[0061] Specifically, the length of the second opening 101b is 310mm-320mm, and the width of the second opening 101b is 120mm-125mm; the length of the upper blade section 211 of the grille blade 21 located in the second opening 101b is 5mm-5.5mm, the length of the lower blade section 212 of the grille blade 21 located in the second opening 101b is 7.5mm-8mm, and the angle between the upper blade section 211 and the lower blade section 212 of the grille blade 21 located in the second opening 101b is 150°-155°; the angle between the second surface of the lower blade section 212 of the grille blade 21 located in the second opening 101b and the horizontal plane is 160°-170°.

[0062] Combination Fig.11 and Fig.12 As shown, the second bottom plate portion 12 and the battery pack 3 form a height difference along the height direction of the vehicle.

[0063] In this embodiment, the battery pack 3 includes a top surface 31 and a bottom surface 32 along the height direction of the vehicle, the top surface 31 is closer to the engine room of the vehicle than the bottom surface 32, and the second bottom plate portion 12 is connected to the bottom surface 32. The second bottom plate portion 12 is provided with a first opening 101a at a position farthest from the engine room along the height direction of the vehicle, so that the hot air flow in the engine room flows out at the lowest position of the second bottom plate portion 12, ensuring that the hot air flow will not adhere to and flow toward the rear of the vehicle in a direction parallel to the bottom surface 32 of the battery pack 3 after flowing out of the engine room, thereby avoiding the temperature increase of the bottom surface 32 of the battery pack 3, thereby solving the problem of heat damage of the battery pack 3.

[0064] It should be understood that the height difference between the second bottom plate portion 12 and the battery pack 3 is the distance between the lowest position of the second bottom plate portion 12 and the bottom surface 32 of the battery pack 3 along the height direction of the vehicle.

[0065] Specifically, the height difference between the second bottom plate portion 12 and the bottom surface 32 of the battery pack 3 along the height direction of the vehicle is 20 mm-25 mm.

The front muffler 42 is located in the avoidance hole 102 along the wheelbase direction of the vehicle. According to the outflow direction of the hot air flow in the cabin and the air flow direction at the bottom of the vehicle, the front muffler 42 and the exhaust pipe 41 are set to an "L"-shaped structure to increase the convection area between the front muffler 42 and the air flow, which is conducive to reducing the temperature of the exhaust pipe 41, thereby reducing the heat radiation effect of the exhaust pipe 41 on surrounding components.

[0068] Specifically, the interval between the exhaust assembly 4 and the bottom guard plate 1 ranges from 50 mm to 60 mm, so as to increase the coverage area of ​​the bottom guard plate 1 and thereby reduce the wind resistance coefficient of the entire vehicle.

[0069] In this embodiment, combined with Figure 5 As shown, the first bottom plate portion 11 is provided with a first flange d, and the second bottom plate portion 12 is provided with a second flange e. The first flange d and the second flange e are beneficial to improving the stiffness and strength performance of the bottom guard plate 1, and are also beneficial to reducing the airflow outside the cabin flowing into the cabin, thereby improving the wind resistance performance of the vehicle.
