[0002] With the development of technology, new energy vehicles are becoming more and more popular. Moreover, with the development of vehicle technology, vehicles have more and more functions, resulting in higher and higher heat dissipation requirements for vehicles. However, the existing vehicle heat dissipation systems cannot meet the required heat dissipation needs, resulting in too high a heat load in the engine compartment, which easily causes the vehicle to accumulate too much waste heat and affects vehicle performance. Summary of the Utility Model

[0003] The utility model aims to solve at least one of the technical problems existing in the prior art. For this purpose, the utility model provides a vehicle, which can improve the heat dissipation capacity.

[0004] The vehicle according to an embodiment of the utility model includes: a vehicle body, an engine compartment is provided at the front of the vehicle body, an air inlet is provided at the front side of the engine compartment, and an air intake grille is provided at the air inlet; an intercooler, the intercooler is arranged in the engine compartment and is located on the downstream side of the air intake grille in the air flow direction; a heat dissipation assembly, the heat dissipation assembly is arranged on the downstream side of the intercooler in the air flow direction, and the heat dissipation assembly is provided with fan blades, and the fan blades are used to drive the air after exchanging heat with the intercooler to flow out of the engine compartment through the heat dissipation assembly; a bottom guard plate, the bottom guard plate is located below the intercooler and the heat dissipation assembly, and the bottom guard plate is provided with an exhaust port, and the exhaust port is located on the downstream side of the intercooler in the air flow direction to discharge the air exchanged heat with the intercooler out of the vehicle.

[0005] According to the vehicle of the embodiment of the utility model, the intercooler is located at the rear end of the intake assembly in the front-rear direction of the whole vehicle, and the intercooler is provided with fan blades, and the fan blades are used to exhaust the air cooled by the intercooler after passing through the intake assembly out of the vehicle, and the bottom guard plate is located at the lower end of the intercooler in the up-down direction of the whole vehicle, and is used to discharge the air passing through the intercooler out of the vehicle, effectively increasing the exhaust volume of the vehicle engine compartment, increasing the effective exhaust volume of the intercooler, improving the heat dissipation efficiency of the intercooler, and enhancing the vehicle heat dissipation capacity.

[0006] In some embodiments, the bottom guard plate is spaced apart from the heat dissipation assembly in the vertical direction to jointly define an exhaust passage, the exhaust passage is located on the side of the intercooler facing away from the air intake grille, and is communicated with the exhaust port.

[0007] In this way, the exhaust passage is formed by using the bottom guard plate and the heat dissipation assembly, which can enable the air flow after exchanging heat with the intercooler to flow smoothly to the exhaust port through the exhaust passage, improve the air flow circulation efficiency, and save the separate setting of channel structure members for forming the exhaust passage, making the exhaust passage vehicle structure relatively simple and easy to implement.

[0008] In some embodiments, a part of the structure of the intercooler extends downward beyond the heat dissipation assembly. The bottom guard plate includes: a plate body; an air outlet structure that protrudes upward from the plate body, and the exhaust port is provided on the air outlet structure. The exhaust port and the part of the intercooler that extends downward beyond the heat dissipation assembly are arranged opposite to each other in the front-rear direction.

[0009] In this way, a part of the intercooler faces the heat dissipation assembly, and the other part faces the exhaust port. So that a part of the air flowing through the intercooler can flow through the heat dissipation assembly and be discharged out of the engine compartment, and the other part of the air can be discharged out of the engine compartment through the exhaust port, increasing the heat dissipation path, improving the heat dissipation efficiency, and enhancing the vehicle reliability. In addition, a part of the structure of the intercooler extends downward beyond the heat dissipation assembly, which facilitates separating the bottom guard plate and the heat dissipation assembly by a certain distance in the vertical direction to form an exhaust passage, and can also increase the layout space of the intercooler, thereby enabling the installation of an intercooler with a larger volume and higher heat dissipation performance.

[0010] In some embodiments, the bottom guard plate further includes: a support structure that protrudes upward from the plate body, and the support structure is provided with fixing holes. The support structure is fixedly connected to the intercooler through the fixing holes; a wind guiding and strengthening structure, and there are multiple wind guiding and strengthening structures. The multiple wind guiding and strengthening structures are spaced between the support structures and are located on the front side of the exhaust port.

[0011] In this way, the support structure is fixed to the intercooler through the fixing holes, facilitating the stability of the intercooler. The multiple wind guiding and strengthening structures can strengthen the bottom guard plate, ensure the strength of the bottom guard plate, and at the same time can guide the air passing through the intercooler into the exhaust port and be discharged from the vehicle.

[0012] In some embodiments, a heat dissipation strengthening structure is provided on the exhaust port, and the heat dissipation strengthening structure divides the exhaust port into multiple heat dissipation holes.

[0013] By providing the heat dissipation strengthening structure, on the one hand, it is beneficial to strengthen the strength of the exhaust port to ensure the strength of the bottom guard plate. On the other hand, the heat dissipation strengthening structure can divide the exhaust port into multiple heat dissipation holes.

[0014] In some embodiments, the bottom guard plate is provided with a front-end strengthening structure, and the front-end strengthening structure is symmetrically arranged along the left-right direction of the vehicle.

[0015] In this way, the strength of the front end of the bottom guard plate can be ensured. The symmetrical design is more stable, with uniform stress, meeting the requirements of actual working conditions.

[0016] In some embodiments, the bottom guard plate is provided with a bottom strengthening structure, and the bottom strengthening structure is trapezoidal or triangular, and the bottom strengthening structure is connected to the air outlet structure.

[0017] By providing a bottom reinforcement structure, while effectively strengthening the strength at the exhaust port of the bottom guard plate, the air volume discharged from the exhaust port is not affected.

[0018] In some embodiments, the vehicle further includes a sealing structure, which is provided on the bottom guard plate and located on at least one side of the air outlet structure along the front-rear direction of the vehicle. The sealing structure is in sealing cooperation with at least one of the intercooler and the heat dissipation assembly to prevent air turbulence during the intake and / or exhaust processes.

[0019] In this way, a stable working environment is provided for the intercooler to prevent the airflows from disturbing each other during the intake or exhaust process. Moreover, it can also ensure that the airflows passing through the exhaust port are all the airflows that have exchanged heat with the intercooler, thereby preventing the airflows from being discharged to the exhaust port through the gap between the intercooler and the bottom guard plate without exchanging heat with the intercooler after entering the engine compartment, which helps to improve the heat dissipation efficiency of the intercooler.

[0020] In some embodiments, the sealing structure is adhesively connected to the bottom guard plate; and / or, the sealing structure is at least one of a rubber sheet and a non-woven fabric piece.

[0021] In this way, it is ensured that the connection between the sealing structure and the bottom guard plate is reliable, and the adhesive operation is simple and easy to install, improving the assembly efficiency. It can also meet the requirements of sealing, noise reduction, and shock absorption.

[0022] In some embodiments, the bottom guard plate is further provided with a mounting structure, and the bottom guard plate is fixedly mounted on the vehicle body through the mounting structure.

[0023] In this way, the cooperation mode between the bottom guard plate and the vehicle body is relatively simple and easy to assemble.

[0039] In order to make the above objects, features, and advantages of the embodiments of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the scope of protection of the present application.

[0040] Next, refer to Figures 1 - 7 to describe the vehicle 1000 in the embodiment of the present utility model.

[0041] As Figure 1 , Figure 5 and Figure 6As shown, the vehicle 1000 according to an embodiment of the present utility model may include a vehicle body 1, an intercooler 2, a heat dissipation assembly 4, and a bottom guard plate 3.

[0042] Specifically, a cabin 10 is provided at the front of the vehicle body 1. The cabin 10 can be used to arrange the motor, controller, air filter, air conditioning system, cooling system, and other types of functional components of the vehicle 1000. An air inlet 101 is provided on the front side of the cabin 10. An air intake grille 11 is provided at the air inlet 101. During the driving of the vehicle 1000, air can enter the cabin 10 through the air inlet 101 to dissipate heat from the components in the cabin 10. The air intake grille 11 can block relatively large foreign objects from entering the cabin 10, effectively protecting the intercooler 2 or other devices inside the vehicle 1000. An air outlet passage (not shown in the figure) can be provided in the cabin 10 to facilitate the air carrying heat to be discharged to the outside through the air outlet passage.

[0043] The intercooler 2 is provided in the cabin 10. The intercooler 2 is located on the downstream side of the air intake grille 11 in the air flow direction. After the air flow passes through the air intake grille 11, it flows through the intercooler 2 and exchanges heat with the intercooler 2, thereby taking away the heat of the intercooler 2 and dissipating heat from the intercooler 2.

[0044] The heat dissipation assembly 4 is provided on the downstream side of the intercooler 2 in the air flow direction. The heat dissipation assembly 4 is provided with fan blades. The fan blades are used to drive the air that has exchanged heat with the intercooler 2 to flow out of the cabin 10 through the heat dissipation assembly 4. In this way, the heat dissipation assembly 4 can play a role in dissipating heat from the intercooler 2 and driving the air flow. It can be understood that the fan blades can drive the air that has exchanged heat with the intercooler 2 to flow out of the cabin 10 through the heat dissipation assembly 4 and the air outlet passage.

[0045] The bottom guard plate 3 can be installed at the bottom of the vehicle body 1. The bottom guard plate 3 is located below the intercooler 2 and the heat dissipation assembly 4. The bottom guard plate 3 can withstand the impact of foreign objects at the bottom of the vehicle 1000, thereby providing protection for the vehicle body 1. To improve the heat dissipation capacity of the cabin 10, an exhaust port 320 is provided on the bottom guard plate 3. The exhaust port 320 is on the downstream side of the intercooler 2 in the air flow direction to discharge the air that has exchanged heat with the intercooler 2 out of the vehicle.

[0046] That is to say, the vehicle 1000 in the embodiment of the present application is provided with at least two heat dissipation paths, namely a first heat dissipation path and a second heat dissipation path. Among them, the first heat dissipation path is that the air sequentially passes through the air intake grille 11, the intercooler 2, the heat dissipation assembly 4, and the air outlet passage of the cabin 10 to complete heat dissipation, and the second heat dissipation path is that the air sequentially passes through the air intake grille 11, the intercooler 2, and the exhaust port 320 of the bottom guard plate 3 to complete heat dissipation.

[0047] The heat dissipation principle of the vehicle 1000 according to the embodiments of the present application is as follows: When the vehicle 1000 is idling or traveling at a low speed, there is no oncoming wind or the oncoming wind speed is relatively low for the whole vehicle, and the heat load of the intercooler 2 is relatively low. At this time, the air circulation path is: The outside air enters the engine compartment 10 through the intake grille 11, and then after heat exchange with the intercooler 2, the airflow is driven by the fan blades of the heat dissipation assembly 4 to be discharged outside the vehicle through the air outlet channel of the engine compartment 10 for heat dissipation; When the vehicle 1000 is traveling at medium and high speeds, the oncoming wind speed of the whole vehicle is high, and the heat load of the intercooler 2 is large. At this time, a part of the air can be exhausted through the above-mentioned first heat dissipation path, and another part of the air will be exhausted through the second heat dissipation path, that is, the outside air enters the engine compartment 10 through the intake grille 11, and then after heat exchange with the intercooler 2, it is dissipated through the exhaust port 320 on the bottom guard 3. Thus, it is possible to adjust the exhaust air volume of the vehicle 1000, and meet the exhaust air volume requirements of the intercooler 2 under different conditions. Especially in the high-speed state, the exhaust port 320 of the bottom guard 3 can effectively increase the heat dissipation of the intercooler 2, so as to avoid the temperature inside the front engine compartment 10 of the vehicle 1000 from being too high, thereby improving the reliability of the vehicle 1000.

[0048] In the vehicle 1000 according to the embodiments of the present application, the intercooler 2 is located at the rear side of the intake grille 11 along the front-rear direction of the whole vehicle, and the heat dissipation assembly 4 is provided with fan blades for driving the air after heat exchange with the intercooler 2 to be discharged outside the vehicle. The bottom guard 3 is located at the lower end of the intercooler 2 along the up-down direction of the whole vehicle for exhausting the air passing through the intercooler 2 outside the vehicle through the exhaust port 320. In this way, the airflow entering the engine compartment 10 from the intake grille 11 can be discharged either through the heat dissipation assembly 4 or only through the exhaust port 320 of the bottom guard 3 after heat exchange with the intercooler 2, increasing the effective exhaust area of the intercooler 2 to increase the exhaust air volume at the front end of the vehicle 1000, which can improve the heat exchange efficiency of the intercooler 2, enhance the heat dissipation capacity, and improve the overall vehicle heat dissipation performance, and can meet the use requirements of the vehicle 1000 in a high-temperature environment. In addition, since the exhaust port 320 is provided on the bottom guard 3 that the vehicle 1000 itself has, it is possible to avoid changing the structure of the front part of the vehicle 1000 and reduce the development cost.

[0049] In some embodiments, the bottom guard 3 and the heat dissipation assembly 4 are spaced apart vertically. In this way, the bottom guard 3 and the heat dissipation assembly 4 can jointly define an exhaust passage 38. The exhaust passage 38 is located on the side of the intercooler 2 facing away from the intake grille 11, and the exhaust passage 38 is communicated with the exhaust port 320. Thus, by forming the exhaust passage 38 with the bottom guard 3 and the heat dissipation assembly 4, it is possible to make the airflow passing through the intercooler 2 flow smoothly to the exhaust port 320 through the exhaust passage 38, improve the airflow circulation efficiency, and moreover, save the need to separately set a channel structure member for forming the exhaust passage 38, making the structure of the exhaust passage 38 of the vehicle 1000 relatively simple and easy to implement.

[0050] In some embodiments, a part of the intercooler 2 extends downward beyond the heat dissipation assembly 4. In other words, the bottom end of the intercooler 2 is located below the bottom end of the heat dissipation assembly 4. The bottom guard plate 3 may include: a plate body 30 and an air outlet structure 32. Among them, the plate body 30 may be connected to the vehicle body 1 to serve as a bottom protection member of the vehicle body 1. The air outlet structure 32 protrudes upward from the plate body 30, and an exhaust port 320 is provided in the air outlet structure 32. The exhaust port 320 and the part of the intercooler 2 that extends downward beyond the heat dissipation assembly 4 are arranged opposite to each other in the front-rear direction. Here, the opposite arrangement may be that the opening direction of the exhaust port 320 is perpendicular to the intercooler 2, or it may have a certain inclination angle with the intercooler 2.

[0051] In this way, a part of the intercooler 2 faces the heat dissipation assembly 4, and another part faces the exhaust port 320, so that a part of the air flowing through the intercooler 2 can flow through the heat dissipation assembly 4 and be discharged out of the engine compartment 10, and another part of the air can pass through the exhaust port 320 and be discharged out of the engine compartment 10, increasing the heat dissipation path, improving the heat dissipation efficiency, and improving the reliability of the vehicle 1000. In addition, a part of the structure of the intercooler 2 extends downward beyond the heat dissipation assembly 4, which is convenient for spacing the bottom guard plate 3 and the heat dissipation assembly 4 apart vertically by a certain distance, so as to form an exhaust passage 38, and can also increase the layout space of the intercooler 2, so as to set an intercooler 2 with a larger volume and higher heat dissipation performance.

[0052] In some embodiments of the present utility model, as Figure 2 shown, the bottom guard plate 3 may further include a support structure 31. The support structure 31 is provided with a fixing hole 311, so that the support structure 31 is fixed to the intercooler 2 through the fixing hole 311, which is convenient for the stability of the intercooler 2. Optionally, the support structure 31 may be a support boss, and there may be multiple support structures 31. The multiple support structures 31 may be arranged at intervals in the left-right direction of the vehicle 1000. By connecting the multiple support structures 31 to the intercooler 2, the installation stability of the intercooler 2 can be further improved.

[0053] In addition, as Figure 2 shown, the bottom guard plate 3 further includes a wind guiding and strengthening structure 33. The wind guiding and strengthening structure 33 may be a wind guiding rib plate, and the wind guiding rib plate may extend in the front-rear direction of the vehicle 1000. The number of the wind guiding and strengthening structures 33 is multiple, and multiple means two or more. Optionally, there are two support structures 31, and multiple wind guiding and strengthening structures 33 may be arranged at intervals in the left-right direction of the vehicle 1000 and provided between the support structures 31, so as to strengthen the bottom guard plate 3, ensure the strength of the bottom guard plate 3, and at the same time can guide the air passing through the intercooler 2 into the exhaust port 320 and be discharged from the vehicle 1000.

[0054] In the embodiments of the present utility model, the exhaust port 320 may be set according to actual conditions.

[0055] For example, in some embodiments, the exhaust port 320 is provided to include a heat dissipation hole 322, and the air passing through the lower part of the intercooler 2 can be discharged outside the vehicle 1000 through the heat dissipation hole 322, effectively improving the air discharge volume.

[0056] Alternatively, in some alternative embodiments, a heat dissipation strengthening structure 321 can be provided on the exhaust port 320. For example, the heat dissipation structure can include a plurality of heat dissipation partition ribs. By providing the heat dissipation strengthening structure 321, on the one hand, it is beneficial to strengthen the strength of the exhaust port 320 to ensure the strength of the bottom guard plate 3, and on the other hand, the heat dissipation strengthening structure 321 can divide the exhaust port 320 into a plurality of heat dissipation holes 322.

[0057] Optionally, the shape of the heat dissipation hole 322 can be rectangular, square, circular or any other shape. In this way, the structure of the heat dissipation hole 322 is relatively simple and easy to manufacture and implement.

[0058] For example, in some embodiments, as Figure 5 and Figure 6 shown, the heat dissipation component can include a heat dissipation fan 41. The heat dissipation fan 41 includes the above-mentioned fan blades. The heat dissipation fan 41 is provided at the rear side of the intercooler 2 (for example, Figure 5 the rear side shown in

[0059] ). Through the heat dissipation fan 41, heat dissipation of the intercooler 2 can be achieved, ensuring good heat dissipation effect at the front end of the vehicle 1000, and the air flow can be changed by controlling the heat dissipation fan 41. Figure 5 As Figure 5 shown, when the heat dissipation requirement at the front end of the vehicle 1000 is small, for example, in the low-speed state, due to the vehicle 1000 idling, starting, and using fewer electrical appliances (such as turning off the air conditioner and multimedia), etc., resulting in a small heat dissipation requirement at the front end of the vehicle 1000, the heat dissipation fan 41 is controlled to rotate at a low speed, and the air flow can be discharged outside the vehicle through the first heat dissipation path, as

[0060] the arrows shown in Figure 6 . Since the area of the intake grille 11 is limited in the low-speed state, the air intake volume can meet the working conditions requirements. Figure 6 shown, when the vehicle 1000 is traveling at a high speed, due to the vehicle 1000 running at a high speed instantaneously, stepping on the accelerator deeply, traveling at a high speed, and increasing the use of electrical appliances (such as turning on the air conditioner and multimedia), etc., resulting in a large heat dissipation requirement at the front end of the vehicle 1000, the heat dissipation fan 41 is controlled to rotate at a high speed. Part of the air flow is discharged outside the vehicle through the first heat dissipation path, and another part of the air flow can also be discharged outside the vehicle through the second heat dissipation path, as

[0061] In the existing solutions, due to the relatively high vehicle speed, the amount of air intake passing through the intake grille is large enough to meet the heat exchange requirements of the intercooler. However, the air discharged after being cooled by the intercooler cannot be discharged in time. In this application, the exhaust port 320 provided on the bottom guard 3 can effectively discharge the air passing through the intercooler 2 from the vehicle 1000, effectively reducing the temperature of the engine compartment 10. For example, the flow path of the air flow is as Figure 6 shown by the arrow in

[0062] In some embodiments of the present utility model, as Figure 2 shown, the bottom guard 3 is provided with a front-end strengthening structure 34. The front-end strengthening structure 34 is symmetrically arranged along the left-right direction of the whole vehicle to ensure the strength of the front end of the bottom guard 3. The symmetrical design is more stable, with uniform stress, meeting the requirements of actual working conditions.

[0063] In addition, as Figure 2 shown, the vehicle 1000 further includes a sealing structure 36. The sealing structure 36 is arranged on the upper surface of the bottom guard 3. The sealing structure 36 is located on at least one side of the air outlet structure 32 along the front-rear direction of the vehicle 1000. The sealing structure 36 is in sealing cooperation with at least one of the intercooler 2 and the heat dissipation component 4 to prevent air turbulence during the intake and / or exhaust process.

[0064] For example Figure 2 shown, the sealing structure 36 is arranged on the front side of the air outlet structure 32, and the sealing structure 36 is in sealing cooperation with the lower surface of the intercooler 2. In this way, a stable working environment is provided for the intercooler 2 to prevent air turbulence between air flows during the intake or exhaust process. Moreover, it can also ensure that the air flow passing through the exhaust port 320 is the air flow that has exchanged heat with the intercooler 2, thereby preventing the air flow from entering the engine compartment 10 and being discharged to the exhaust port 320 through the gap between the intercooler 2 and the bottom guard 3 without exchanging heat with the intercooler 2, which helps to improve the heat dissipation efficiency of the intercooler 2.

[0065] In some embodiments, the sealing structure 36 and the bottom guard 3 are adhesively connected, for example, connected by an adhesive. The sealing structure 36 is adhesively bonded to the bottom guard 3 to ensure reliable connection between the sealing structure 36 and the bottom guard 3. And the adhesive operation is simple, easy to install, improving the assembly efficiency. Of course, this application is not limited to this. The connection method between the sealing structure 36 and the bottom guard 3 can also be snap connection, plug connection, etc., and this application does not limit this.

[0066] In some embodiments, the sealing structure 36 can be a rubber sheet. For example, the sealing structure 36 can be ethylene propylene diene monomer (EPDM). The rubber sheet has the characteristics of light weight and high strength, and can meet the requirements of sealing, noise reduction and shock absorption.

[0067] In some embodiments of the present utility model, the sealing structure 36 may be a non-woven fabric member. The non-woven fabric has the characteristics of being lightweight and can meet the requirements of sealing, noise reduction, and shock absorption. Of course, other materials with the same or similar characteristics can also be used for the sealing structure 36.

[0068] In some embodiments of the present utility model, as Figure 4 shown, the bottom guard plate 3 is provided with a bottom strengthening structure 35. The bottom strengthening structure 35 is trapezoidal or triangular, and can also be a structure with the same strengthening property in other geometric shapes. The bottom strengthening structure 35 can be arranged on the side of the bottom guard plate 3 facing away from the intercooler 2 (i.e., the lower side of the bottom guard plate 3). The bottom strengthening structure 35 can be connected to the air outlet structure 32, and the bottom strengthening structure 35 and the exhaust port 320 are arranged at intervals. By setting the bottom strengthening structure 35, while effectively strengthening the strength at the exhaust port 320 of the bottom guard plate 3, the air volume discharged from the exhaust port 320 is not affected.

[0069] In some embodiments, the bottom guard plate 3 is further provided with a mounting structure 37. The bottom guard plate 3 can be fixedly mounted on the vehicle body 1 through the mounting structure 37. For example, the mounting structure 37 can be a mounting threaded hole, and the bottom of the vehicle body 1 can be provided with a mating threaded hole. The bottom guard plate 3 and the vehicle body 1 are connected by fasteners passing through the mounting threaded hole and the mating threaded hole in sequence. In this way, the cooperation mode between the bottom guard plate 3 and the vehicle body 1 is relatively simple and easy to assemble.

[0070] In summary, for the vehicle 1000 according to the embodiments of the present utility model, through the exhaust port 320 provided on the bottom guard plate 3, the air flow entering from the intake grille 11 can flow to the intercooler 2. After the air is heat-exchanged by the intercooler 2, a part of the air is discharged through the heat dissipation component 4 and the air outlet channel of the engine compartment 10, and the other part is discharged from the exhaust port 320 of the bottom guard plate 3. This can increase the air discharge volume at the front end of the vehicle 1000, thereby increasing the effective exhaust area of the intercooler 2, improving the heat exchange efficiency of the intercooler 2, enhancing the heat dissipation capacity, and strengthening the heat dissipation performance of the vehicle 1000. It can meet the use requirements of the vehicle 1000 in a high-temperature environment, and avoid making other styling changes to the front end of the vehicle 1000, which can reduce the development cost.

[0071] It can be understood that as the power of the power system of the vehicle 1000 increases, the heat dissipation requirement at the front end of the vehicle 1000 becomes higher. Through the exhaust port 320, the air discharge volume of the heat dissipation system of the vehicle 1000 can be increased to meet the air discharge volume requirement of the intercooler 2, thereby meeting the requirements of the vehicle 1000 in terms of power performance, low wind resistance, economy, and fashionability, and improving the user experience.

[0072] In some embodiments of the present utility model, the bottom guard plate 3 can be disposed on the engine compartment underguard of the vehicle 1000. For example, the bottom guard plate 3 can be installed or integrated on the engine compartment underguard, so that the bottom guard plate 3 has strong compatibility and applicability and can meet different assembly requirements.

[0073] It should be noted that the embodiments referred to in the specification, such as "an embodiment", "embodiments", "exemplary embodiments", "some embodiments", etc., may include specific features, structures or characteristics, but not necessarily every embodiment includes such specific features, structures or characteristics. In addition, such phrases do not necessarily refer to the same embodiment. Moreover, when combining specific features, structures or characteristics with an embodiment, implementing such features, structures or characteristics in other embodiments, whether explicitly or implicitly described, is within the knowledge scope of those skilled in the art.

[0074] Generally speaking, terms should be understood at least in part by their use in the context. For example, at least in part according to the context, the term "one or more" used in the text can be used to describe any feature, structure or characteristic in the sense of singularity, or can be used to describe a combination of features, structures or characteristics in the sense of plurality. Similarly, at least in part according to the context, terms such as "a" or "the" can also be understood to convey singular usage or plural usage.

[0075] It should be easily understood that the terms "on", "above" and "over" in this disclosure should be interpreted in the broadest manner, so that "on" not only means "directly on something", but also includes the meaning of "on something" with intermediate features or layers therebetween, and "above" or "over" not only includes the meaning of "above" or "over something", but also can include the meaning of "above" or "over something" without intermediate features or layers therebetween (i.e., directly on something).

[0076] In addition, for the convenience of description, spatial relative terms can be used in the text, such as "below", "beneath", "under", "above", "over", etc., to describe the relationship of one element or feature relative to other elements or features as shown in the figure. Spatial relative terms are intended to include different orientations of the device in use or operation other than the orientation shown in the drawings. The device can have other orientations (rotated 90 degrees or in other orientations), and the spatial relative descriptive words used in the text can be similarly interpreted accordingly.
