Description

Technical Field

[0001] This application relates to the field of vehicle technology, and in particular to a front engine compartment underbody protection panel and a vehicle. Background Technology

[0002] To improve vehicle aerodynamics and reduce wind resistance, current vehicles use a full-body skid plate at the bottom of the body, which reduces wind resistance and improves overall NVH performance. However, this solution seals off the entire front engine compartment, forcing outside air to circulate only within the compartment after entering through the radiator, thus reducing the cooling efficiency of the cooling module. Summary of the Invention

[0003] In view of this, the present invention aims to at least partially solve one of the problems in the related art. Therefore, the object of this application is to provide a front engine compartment underbody protection panel and a vehicle.

[0004] This application provides a front engine compartment underbody protection panel for a vehicle. The front engine compartment underbody protection panel consists of a first panel and a second panel. The first panel is disposed at the front end of the front engine compartment, and the second panel is disposed at the rear end of the front engine compartment. The first panel is disposed along the X-direction of the vehicle body. A predetermined distance is maintained between the first panel and the second panel. The end of the second panel closest to the first panel is connected to a crossbeam in the front engine compartment of the vehicle. The end of the second panel opposite to the first panel is connected to a battery pack mounting bracket of the vehicle.

[0005] Thus, the front nacelle lower guard plate of this application includes a first guard plate and a second guard plate. The second guard plate is located at the rear end of the front nacelle and is separated from the first guard plate located at the front end of the front nacelle by a predetermined distance to form a cavity for convection with the outside. This allows the hot air flowing into the front nacelle and passing through the heat dissipation module to be guided to the atmosphere through the cavity, thereby improving the heat dissipation efficiency of the heat dissipation module.

[0006] In some embodiments, the second skid plate includes a first connecting portion, a guide portion, and a second connecting portion. The first connecting portion is connected to the crossbeam in the front engine compartment. The guide portion is located between the first connecting portion and the second connecting portion, and the guide portion is inclined at a predetermined angle towards the top of the vehicle body. The second connecting portion is connected to the battery pack mounting bracket.

[0007] Thus, the front engine compartment lower guard plate of this application, by setting a guide section located between the first connecting part and the second connecting part, tilts the guide section towards the top of the vehicle body at a preset angle, so that the hot air flowing into the front engine compartment and passing through the heat dissipation module is guided to the atmosphere through the guide component, thereby improving the heat dissipation efficiency of the thermal management module.

[0008] In addition, by connecting the first connecting part to the crossbeam in the front engine compartment and the second connecting part to the battery mounting bracket, this application can form a barrier in front of and below the motor, which can protect the motor from impacts by flying stones on the road when the vehicle is in motion.

[0009] In some embodiments, the first connection is screwed or welded to the crossbeam in the forward engine compartment.

[0010] Thus, the first connecting part of the forward engine compartment lower guard plate of this application is connected to the forward engine compartment crossbeam by bolting, which facilitates replacement when the first connecting part is damaged. In addition, the first connecting part is connected to the forward engine compartment crossbeam by welding, so that the first connecting part can be more firmly connected to the forward engine compartment crossbeam.

[0011] In some embodiments, the second connection is screwed or welded to the battery pack mounting base.

[0012] Thus, the second connecting part of the front nacelle lower guard plate of this application is connected to the battery pack mounting base by screws, which facilitates replacement when the second connecting part is damaged. In addition, the second connecting part is connected to the battery pack mounting base by welding, so that the second connecting part can be more firmly connected to the battery pack mounting base.

[0013] In some embodiments, the angle between the guide portion and the second connecting portion is adjustable.

[0014] Thus, the lower nacelle guard plate of this application is adjustable by setting the angle between the air guide and the second connection, so that the user can adjust the angle between the air guide and the second connection according to the flow rate of hot air flowing into the front nacelle and passing through the heat dissipation module, thereby improving the air guiding performance of the air guide component to guide the hot air into the atmosphere, and further improving the heat dissipation efficiency of the heat dissipation module.

[0015] In some embodiments, the second guard plate further includes a first guard plate bracket, and the first connecting portion is connected to the crossbeam in the forward engine compartment via the first guard plate bracket.

[0016] Thus, the first connecting part of the front engine compartment lower guard plate of this application is connected to the front engine compartment middle crossbeam through the first guard plate bracket. The connection rigidity between the first connecting part and the front engine compartment middle crossbeam can be increased by the first guard plate bracket, so that the first connecting part is more firmly connected to the front engine compartment middle crossbeam.

[0017] In some embodiments, the first guard plate includes a second guard plate bracket, and the first guard plate is connected to the vehicle body longitudinal beam via the second guard plate bracket.

[0018] Thus, the first skid plate of the front engine compartment under guard plate of this application is connected to the longitudinal beam of the vehicle body through the second skid plate bracket. The connection rigidity between the first skid plate and the longitudinal beam of the vehicle body can be increased by the second skid plate bracket, making the first skid plate more firmly connected to the longitudinal beam of the vehicle body.

[0019] In some embodiments, the first guard plate is connected to the second guard plate bracket by screwing or welding.

[0020] Thus, the first skid plate of the front nacelle underbody in this application is connected to the second skid plate bracket by screws, facilitating replacement of the first skid plate when damaged. Furthermore, the first skid plate is connected to the second skid plate bracket by welding, ensuring a more secure connection between the two.

[0021] In some embodiments, the second guard plate bracket is connected to the vehicle body longitudinal beam by screwing or welding.

[0022] Thus, the second skid plate bracket of the front engine compartment underbody protection plate of this application is connected to the vehicle body longitudinal beam by bolts, facilitating replacement when the second skid plate bracket is damaged. In addition, the second skid plate bracket is connected to the vehicle body longitudinal beam by welding, resulting in a more secure connection between the second skid plate bracket and the vehicle body longitudinal beam.

[0023] This application also provides a vehicle. The vehicle includes the front engine compartment underbody protection panel described in the above embodiments.

[0024] Thus, the front engine compartment lower guard plate of the vehicle in this application includes a first guard plate and a second guard plate. The second guard plate is located at the rear end of the front engine compartment and is separated from the first guard plate located at the front end of the front engine compartment by a predetermined distance to form a cavity for convection with the outside. This allows the hot air flowing into the front engine compartment and passing through the heat dissipation module to be guided to the atmosphere through the cavity, thereby improving the heat dissipation efficiency of the heat dissipation module.

[0033] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0034] Please see Figure 1In related technologies, designing the front engine compartment underbody panel as a one-piece molded panel along the X-direction of the vehicle body improves the vehicle's aerodynamics, reduces wind resistance, and enhances NVH performance. However, this solution has a limitation: after entering through the radiator, outside air can only circulate within the engine compartment. That is, once outside air flows into the front engine compartment and becomes hot air after passing through the cooling module, it cannot be promptly channeled into the atmosphere and remains circulated within the engine compartment, resulting in reduced cooling efficiency of the cooling module.

[0035] In view of this, please refer to Figure 2 This application provides a front engine compartment underbody protection plate 100 for a vehicle. The front engine compartment underbody protection plate 100 is divided into a first protection plate 10 and a second protection plate 30. The first protection plate 10 and the second protection plate 30 are separated by a predetermined distance.

[0036] The preset distance can be a pre-set distance, such as 3cm, 3.1cm, 3.2cm, 3.3cm, 3.4cm, 3.5cm, 3.6cm, 3.7cm, 3.8cm, 3.9cm, and 4cm, and there are no restrictions here.

[0037] In other words, by setting a preset distance between the first protective plate 10 and the second protective plate 30, a convection cavity can be formed inside the front engine compartment. This allows the hot air, which becomes hot air after passing through the heat dissipation module 200, to flow back into the atmosphere through the external convection cavity, thereby improving the heat dissipation efficiency of the heat dissipation module 200. Specifically, the heat dissipation module 200 is used to dissipate heat generated inside the front engine compartment. The first protective plate 10 can be positioned directly below the heat dissipation module 200, and the second protective plate 30 can be positioned below and behind the heat dissipation module 200. The cavity formed between the first protective plate 10 and the second protective plate 30 is located precisely behind the heat dissipation module 200, allowing the hot air, which becomes hot air after passing through the heat dissipation module 200, to flow back into the atmosphere through the cavity, thus improving the heat dissipation efficiency of the heat dissipation module 200.

[0038] The first protective plate 10 and the second protective plate 30 can both be made of aluminum alloy, and there are no restrictions on the material. In this way, since aluminum alloy is relatively light and has a certain degree of hardness, the weight of the first protective plate 10 and the second protective plate 30 can be reduced while the rigidity can be improved.

[0039] The first skid plate 10 is disposed at the front end of the engine compartment. The first skid plate 10 is disposed along the X direction of the vehicle body. That is, the first skid plate 10 can extend along the X direction of the vehicle body and is located directly opposite the heat dissipation module 200. The first skid plate 10 can be disposed at the front end of the engine compartment along the X direction of the vehicle body by means of screwing or welding. Thus, the first skid plate 10 of this application can be disposed at the front end of the engine compartment by means of screwing, facilitating the disassembly and replacement of the first skid plate 10. The first skid plate 10 of this application can be disposed at the front end of the engine compartment by means of welding, allowing the first skid plate 10 to be more securely disposed at the front end of the engine compartment.

[0040] The second skid plate 30 is located at the rear end of the front engine compartment. The end of the second skid plate 30 closest to the first skid plate 10 is connected to the crossbeam 300 in the front engine compartment of the vehicle. The end of the second skid plate 30 opposite to the first skid plate 10 is connected to the battery pack mounting bracket 400 of the vehicle.

[0041] Specifically, the end of the second skid plate 30 closest to the first skid plate 10 extends towards the Y direction of the vehicle body and connects to the crossbeam 300 in the front engine compartment. The end of the second skid plate 30 opposite to the first skid plate 10 extends towards the X direction of the vehicle body and connects to the battery pack mounting bracket 400. This separates the motor 500 from the heat dissipation module 200, preventing the heat dissipated by the motor 500 from affecting the heat dissipation performance of the heat dissipation module 200. Additionally, when the vehicle is in motion, the second skid plate 30 can protect the motor 500 from impacts by flying stones on the road.

[0042] The second skid plate 30 can be welded to the rear end of the front engine compartment. Specifically, the end of the second skid plate 30 closest to the first skid plate 10 is connected to the crossbeam 300 in the front engine compartment of the vehicle by welding, and the end of the second skid plate 30 opposite to the first skid plate 10 is connected to the battery pack mounting bracket 400 of the vehicle by welding. Thus, the second skid plate 30 of this application can be welded to the rear end of the front engine compartment, allowing for a more secure installation.

[0043] Furthermore, the second skid plate 30 can be installed at the rear end of the front engine compartment via a screw connection. That is, the end of the second skid plate 30 closest to the first skid plate 10 is connected to the crossbeam 300 in the front engine compartment of the vehicle via a screw connection, and the end of the second skid plate 30 opposite to the first skid plate 10 is connected to the battery pack mounting bracket 400 of the vehicle via a screw connection. Thus, the second skid plate 30 of this application can be installed at the rear end of the front engine compartment via a screw connection, facilitating the removal and replacement of the second skid plate 30.

[0044] Thus, the front nacelle lower guard plate 100 of this application includes a first guard plate 10 and a second guard plate 30. The second guard plate 30 is disposed at the rear end of the front nacelle and is separated from the first guard plate 10 disposed at the front end of the front nacelle by a predetermined distance, so as to form a cavity for convection with the outside, so that the hot air flowing into the front nacelle and passing through the heat dissipation module 200 is guided to the atmosphere through the cavity, thereby improving the heat dissipation efficiency of the heat dissipation module 200.

[0045] Please see Figure 2 In some embodiments, the second protective plate 30 includes a first connecting portion 31, a flow guiding portion 33, and a second connecting portion 35. The first connecting portion 31, the flow guiding portion 33, and the second connecting portion 35 can be integrally formed to improve the connection rigidity of the first connecting portion 31, the flow guiding portion 33, and the second connecting portion 35.

[0046] The air guide section 33 is tilted towards the top of the vehicle body at a preset angle. The preset angle can be, for example, [missing information - likely a specific angle]. Figure 2 The preset angle 'a' can be, for example, 40°, 41°, 42°, 43°, 44°, 45°, 46°, 47°, 48°, 49° and 50°, and there are no restrictions here.

[0047] The first connecting part 31 is connected to the crossbeam 300 in the front engine compartment. The air guide part 33 is located between the first connecting part 31 and the second connecting part 35, and the air guide part 33 is tilted towards the top of the vehicle body at a preset angle. The second connecting part 35 is connected to the battery pack mounting bracket 400. That is, the first connecting part 31 is arranged along the Y direction of the vehicle body and connected to the crossbeam 300 in the front engine compartment, the second connecting part 35 is arranged along the X direction of the vehicle body and connected to the battery pack mounting bracket 400, and the air guide part 33 is located between the first connecting part 31 and the second connecting part 35 and is tilted towards the top of the vehicle body at an angle α, for example, the angle α of the air guide part 33 tilting towards the top of the vehicle body can be 50°.

[0048] Thus, the front engine compartment lower guard plate 100 of this application, by setting the guide section 33 located between the first connecting part 31 and the second connecting part 35, tilts the guide section 33 towards the top of the vehicle body at a preset angle, so that the hot air flowing into the front engine compartment and passing through the heat dissipation module 200 is guided to the atmosphere through the guide section 33, thereby improving the heat dissipation efficiency of the heat dissipation module.

[0049] In addition, by connecting the first connecting part 31 to the crossbeam 300 in the front engine compartment and the second connecting part 35 to the battery mounting base, this application can form a barrier in front of and below the motor 500, which can protect the motor 500 from impacts by flying stones on the road when the vehicle is in motion.

[0050] Please see Figure 2In some embodiments, the first connection portion 31 is connected to the crossbeam 300 in the forward engine compartment by means of screwing or welding.

[0051] The first connecting part 31 can be connected to the crossbeam 300 in the forward engine compartment by means of flange bolts and rivet nuts, which is not limited here.

[0052] Thus, the first connecting part 31 of the forward engine compartment lower guard plate 100 of this application is connected to the forward engine compartment crossbeam 300 by bolting, which facilitates replacement when the first connecting part 31 is damaged. In addition, the first connecting part 31 is connected to the forward engine compartment crossbeam 300 by welding, so that the first connecting part 31 can be more firmly connected to the forward engine compartment crossbeam 300.

[0053] Please see Figure 2 The second connecting part 35 is connected to the battery pack mounting base 400 by screwing or welding.

[0054] The second connecting part 35 can be connected to the battery pack mounting base 400 by means of flange bolts and rivet nuts, which is not limited here.

[0055] Thus, the second connecting portion 35 of the front nacelle lower guard plate 100 of this application is connected to the battery pack mounting base 400 by screwing, which facilitates replacement when the second connecting portion 35 is damaged. In addition, the second connecting portion 35 is connected to the battery pack mounting base 400 by welding, so that the second connecting portion 35 can be more firmly connected to the battery pack mounting base 400.

[0056] Please see Figure 2 In some embodiments, the angle between the guide portion 33 and the second connecting portion 35 is adjustable.

[0057] The included angle can be 50°, 51°, 52°, 53°, 54°, 55°, 56°, 57°, 58°, 59°, and 60°, and is not limited here. That is, the user can adjust the included angle between the airflow guide 33 and the second connecting part 35 according to the heat dissipation requirements of the heat dissipation module 200, thereby improving the airflow guide performance of the airflow guide 33 in guiding hot air into the atmosphere.

[0058] Thus, the lower nacelle guard plate of this application allows the user to adjust the angle between the air guide 33 and the second connecting part 35 according to the flow rate of hot air flowing into the front nacelle and passing through the heat dissipation module 200, thereby improving the air guide performance of the air guide 33 in guiding hot air into the atmosphere and further enhancing the heat dissipation efficiency of the heat dissipation module 200.

[0059] Please see Figure 2In some embodiments, the second skid plate 30 further includes a first skid plate bracket 37. The first connecting portion 31 is connected to the front engine compartment crossbeam 300 via the first skid plate bracket 37.

[0060] The first protective plate bracket 37 can be made of aluminum alloy, and there are no restrictions on its material. Since aluminum alloy is relatively lightweight and has a certain degree of hardness, it can reduce the weight of the first protective plate bracket 37 while increasing its rigidity.

[0061] One end of the first guard plate bracket 37 can be connected to the first connecting part 31 by screwing, and the other end of the first guard plate bracket 37 can also be connected to the crossbeam 300 in the front engine compartment by screwing, so that the first connecting part 31 can be replaced when it is damaged.

[0062] One end of the first skid plate bracket 37 can also be connected to the first connecting part 31 by welding, and the other end of the first skid plate bracket 37 can also be connected to the crossbeam 300 in the front engine compartment by welding, so that the first connecting part 31 is more firmly connected to the longitudinal beam of the vehicle body through the first skid plate bracket 37.

[0063] Thus, the first connecting part 31 of the front engine compartment lower guard plate 100 of this application is connected to the front engine compartment middle beam 300 through the first guard plate bracket 37. The first guard plate bracket 37 can increase the connection rigidity between the first connecting part 31 and the front engine compartment middle beam 300, making the first connecting part 31 more firmly connected to the front engine compartment middle beam 300.

[0064] Please see Figure 2 In some embodiments, the first guard plate 10 includes a second guard plate bracket 11, and the first guard plate 10 is connected to the vehicle body longitudinal beam through the second guard plate bracket 11.

[0065] The material of the second guard plate bracket 11 can be aluminum alloy, and there are no restrictions on its material. In this way, since aluminum alloy is relatively light and has a certain degree of hardness, the weight of the second guard plate bracket 11 can be reduced while its rigidity can be increased.

[0066] Thus, the first skid plate 10 of the front engine compartment underbody protection plate 100 of this application is connected to the vehicle body longitudinal beam through the second skid plate bracket 11. The connection rigidity between the first skid plate 10 and the vehicle body longitudinal beam can be increased by the second skid plate bracket 11, so that the first skid plate 10 is more firmly connected to the vehicle body longitudinal beam.

[0067] Please see Figure 2 In some embodiments, the first protective plate 10 is connected to the second protective plate bracket 11 by screwing or welding.

[0068] The first protective plate 10 can be connected to the second protective plate bracket 11 by means of flange bolts and rivet nuts, which is not restricted here.

[0069] Thus, the first skid plate 10 of the front nacelle lower skid plate 100 of this application is connected to the second skid plate bracket 11 by screwing, which facilitates replacement when the first skid plate 10 is damaged. In addition, the first skid plate 10 is connected to the second skid plate bracket 11 by welding, so that the first skid plate 10 can be more firmly connected to the second skid plate bracket 11.

[0070] Please see Figure 2 In some embodiments, the second guard plate bracket 11 is connected to the vehicle body longitudinal beam by screwing or welding.

[0071] The second guard plate bracket 11 can be connected to the longitudinal beam of the vehicle body by means of flange bolts and rivet nuts, which is not restricted here.

[0072] Thus, the second skid plate bracket 11 of the front engine compartment underbody protection plate 100 of this application is connected to the vehicle body longitudinal beam by bolting, which facilitates replacement when the second skid plate bracket 11 is damaged. In addition, the second skid plate bracket 11 is connected to the vehicle body longitudinal beam by welding, so that the second skid plate bracket 11 can be more firmly connected to the vehicle body longitudinal beam.

[0073] This application also provides a vehicle. The vehicle includes the aforementioned front engine compartment underbody protection 100. The specific front engine compartment underbody protection 100 is as described above and will not be repeated here.

[0074] Thus, the front engine compartment lower guard plate 100 of the vehicle of this application includes a first guard plate 10 and a second guard plate 30. The second guard plate 30 is disposed at the rear end of the front engine compartment and is separated from the first guard plate 10 disposed at the front end of the front engine compartment by a predetermined distance, so as to form a cavity for convection with the outside, so that the hot air flowing into the front engine compartment and passing through the heat dissipation module 200 is guided to the atmosphere through the cavity, thereby improving the heat dissipation efficiency of the heat dissipation module 200.

[0075] The above embodiments merely illustrate several implementation methods of this application, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
