Description

Technical Field

[0001] The present invention relates to the technical field of vehicles, and in particular to a vehicle bottom guard plate and a vehicle. Background Art

[0002] The underbody guard is a protective device that is customized for each vehicle model and attached to the bottom of the vehicle. Its functions include: (1) preventing water or foreign objects such as mud and sand from splashing into the engine compartment during driving, and keeping the engine compartment and chassis components clean; (2) preventing rain, ice and snow from corroding the chassis system; (3) resisting the scratching of the chassis system by abnormally raised ground during driving, and the knocking of the exposed engine compartment and oil pipelines by the wheels rolling over the gravel and hard objects on the road; (4) reducing the resistance of the air flow entering the bottom of the car, reducing the lift caused by turbulence, and improving the driving stability of the whole vehicle; (5) reducing the air vortex at the bottom of the car body, reducing air resistance, and improving fuel economy.

[0003] The underbody guard is a flat plate, boxed or other part attached to the bottom of the vehicle body, and is generally made by injection molding, compression molding or other processes. However, after covering the parts on the chassis, the heat dissipation of the parts becomes worse than that of the parts not covered by the underbody guard. For example, the underbody guard is designed at the bottom of the engine to isolate and protect the cabin and the bottom of the engine. However, the engine is a continuous source of power, which is converted into mechanical energy through gasoline or diesel, and will inevitably release a lot of heat. If it is partially overheated, it will affect its work. Summary of the invention

[0004] In order to solve the above technical problem or at least partially solve the above technical problem, the present invention provides a vehicle underbody guard plate and a vehicle.

[0005] In the first aspect, the present application provides a vehicle underbody guard plate, which may include: a plurality of heat dissipation groups, wherein the plurality of heat dissipation groups are spaced apart in the left-right direction of the vehicle, each of the heat dissipation groups includes a plurality of heat dissipation ports, wherein the plurality of heat dissipation ports are spaced apart in the front-rear direction of the vehicle, the heat dissipation ports penetrate the vehicle underbody guard plate, the heat dissipation ports include a first edge and a second edge opposite to each other in the front-rear direction of the vehicle, the first edge being located in front of the second edge; a first guide plate, wherein the first guide plate includes a first end edge and a second end edge opposite to each other, the first end edge being connected to the first edge, and the first guide plate extends obliquely toward the ground in a direction from the first end edge toward the second end edge; a second guide plate, wherein the second guide plate includes a third end edge and a fourth end edge opposite to each other, the third end edge being connected to the second end edge, and a plane where the second guide plate is located is parallel to a plane where the heat dissipation ports are located; wherein the fourth end edge is located between the second edge and the first edge.

[0006] It can be understood that, during the movement of the vehicle, the air flow rate on the side of the vehicle bottom guard facing the ground (i.e., the side where the lower surface of the vehicle bottom guard is located) is greater than the air flow rate on the side of the vehicle bottom guard facing away from the ground (i.e., the side where the upper surface of the vehicle bottom guard is located), then the high-speed airflow will form a negative pressure area on the side of the vehicle bottom guard facing the ground, while a high pressure area will be formed on the side of the vehicle bottom guard facing away from the ground. By providing a heat dissipation port on the vehicle bottom guard, the air in the high-pressure area on the upper side of the vehicle bottom guard flows toward the negative pressure area on the lower side, thereby taking away the heat on the upper side of the vehicle bottom guard (the heat generated by the engine or battery), thereby achieving the heat dissipation effect.

[0007] Furthermore, the present application sets a first guide plate, which, on the one hand, guides the airflow and directs it to flow in an oblique rearward direction; on the other hand, the airflow is compressed by the inclined surface, and the airflow speed increases, further improving the heat dissipation effect of the vehicle's underbody guard plate.

[0008] By setting up a second guide plate, it can be ensured that the airflow passing through the first guide plate can flow toward the rear along the extension direction of the second guide plate, while increasing the distance that the high-speed airflow on the lower side of the vehicle's bottom guard plate drives the low-speed airflow, thereby increasing the stability of the airflow direction.

[0009] Furthermore, when the vehicle is moving, by providing the first guide plate and the second guide plate, the occurrence of wind inflow at the front side of the heat dissipation port can be avoided, the stability of the gas flow path on the upper and lower sides of the vehicle's bottom guard plate can be ensured, and the occurrence of redundant airflow on the upper side of the vehicle's bottom guard plate, which affects the heat dissipation effect, can be avoided.

[0010] At the same time, by arranging the first guide plate and the second guide plate at the first edge, it is possible to effectively prevent gravel and sand from directly rushing into the upper side of the vehicle bottom guard plate, thereby reducing the protective effect of the vehicle bottom guard plate.

[0011] In some embodiments of the present application, the vehicle underbody guard plate also includes: a third guide plate, the third guide plate includes a fifth end edge and a sixth end edge relative to each other, the fifth end edge is connected to the fourth end edge, and in the direction from the fifth end edge toward the sixth end edge, the third guide plate extends obliquely toward the ground; wherein the sixth end edge is located between the second edge and the first edge.

[0012] In some embodiments of the present application, the vehicle bottom guard plate also includes: a fourth guide plate, the fourth guide plate includes a seventh end edge and an eighth end edge relative to each other, the seventh end edge is connected to the sixth end edge, and the plane where the fourth guide plate is located is parallel to the plane where the heat dissipation port is located; wherein the eighth end edge is located between the second edge and the first edge.

[0013] In some embodiments of the present application, the heat dissipation port also includes a third edge and a fourth edge opposite to each other in the left and right directions of the vehicle; the vehicle bottom guard plate also includes a first connecting plate, the first connecting plate is located on the side of the heat dissipation port close to the third edge, one end of the first connecting plate is connected to the third edge, and the other end is connected to the first guide plate.

[0015] In some embodiments of the present application, the vehicle bottom guard plate also includes: a third connecting plate, the third connecting plate is located on the side of the heat dissipation port close to the third edge, and the third connecting plate is respectively connected to the third edge, the first connecting plate and the second guide plate.

[0016] In some embodiments of the present application, the third connecting plate extends to the second edge.

[0032] In order to more clearly understand the above-mentioned objectives, features and advantages of the present invention, the scheme of the present invention will be further described below. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0033] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present invention, rather than all of the embodiments.

[0034] The underbody guard is a protective device that is customized for each vehicle model and attached to the bottom of the vehicle. Its functions include: (1) preventing water or foreign objects such as mud and sand from splashing into the engine compartment during driving, and keeping the engine compartment and chassis components clean; (2) preventing rain, ice and snow from corroding the chassis system; (3) resisting the scratching of the chassis system by abnormally raised ground during driving, and the knocking of the exposed engine compartment and oil pipelines by the wheels rolling over the gravel and hard objects on the road; (4) reducing the resistance of the air flow entering the bottom of the car, reducing the lift caused by turbulence, and improving the driving stability of the whole vehicle; (5) reducing the air vortex at the bottom of the car body, reducing air resistance, and improving fuel economy.

[0035] The underbody guard is a flat plate, boxed or other part attached to the bottom of the vehicle body, and is generally made by injection molding, compression molding or other processes. However, after covering the parts on the chassis, the heat dissipation of the parts becomes worse than that of the parts not covered by the underbody guard. For example, the underbody guard is designed at the bottom of the engine to isolate and protect the cabin and the bottom of the engine. However, the engine is a continuous source of power, which is converted into mechanical energy through gasoline or diesel, and will inevitably release a lot of heat. If it is partially overheated, it will affect its work.

[0036] To solve the above technical problems, please refer to Figure 1 The present application provides a vehicle, which may include a vehicle underbody guard plate 100 and a vehicle frame, wherein the vehicle underbody guard plate 100 is mounted on the vehicle frame.

[0037] Among them, see Figure 1 and Figure 2 The vehicle bottom guard plate 100 may include a plurality of heat dissipation groups, a first guide plate 120 and a second guide plate 130. The plurality of heat dissipation groups are spaced apart in the left-right direction of the vehicle (i.e., the Y direction of the vehicle coordinate system). Each heat dissipation group includes a plurality of heat dissipation ports 110. The plurality of heat dissipation ports 110 are spaced apart in the front-rear direction of the vehicle (i.e., the X-axis direction of the vehicle coordinate system). The heat dissipation ports 110 penetrate the vehicle bottom guard plate 100. It can be understood that in the left-right direction, the connected heat dissipation ports 110 may be arranged relative to each other, may be arranged overlappingly, or may be arranged staggered.

[0038] Understandably, see Figure 2 and Figure 3 When the vehicle is moving, the air flow speed on the side of the vehicle bottom guard plate 100 facing the ground (i.e., the side where the lower surface of the vehicle bottom guard plate 100 is located) is greater than the air flow speed on the side of the vehicle bottom guard plate 100 facing away from the ground (i.e., the side where the upper surface of the vehicle bottom guard plate 100 is located). Then, the high-speed airflow will form a negative pressure area on the side of the vehicle bottom guard plate 100 facing the ground, and a high pressure area on the side of the vehicle bottom guard plate 100 facing away from the ground. By arranging the heat dissipation port 110 on the vehicle bottom guard plate 100, the air in the high-pressure area on the upper side of the vehicle bottom guard plate 100 flows toward the negative pressure area on the lower side, taking away the heat on the upper side of the vehicle bottom guard plate 100 (the heat generated by the engine or battery), thereby achieving the heat dissipation effect.

[0039] Please continue reading Figure 2 and Figure 3The heat dissipation outlet 110 may include a first edge 111 and a second edge 112 opposite to each other in the front-rear direction of the vehicle, the first edge 111 being located in front of the second edge 112, the first guide plate 120 may include a first end edge and a second end edge opposite to each other, the first end edge being connected to the first edge 111, and the first guide plate 120 extends obliquely toward the ground in a direction from the first end edge toward the second end edge, that is, the first guide plate 120 extends toward the rear and lower portion of the vehicle.

[0040] In this way, by setting the first guide plate 120, on the one hand, it guides the airflow and guides it to flow in the oblique rearward direction; on the other hand, the airflow is compressed by the inclined surface, the airflow speed will increase, and the heat dissipation effect of the vehicle bottom guard plate 100 will be further improved.

[0041] The second guide plate 130 includes a third end edge and a fourth end edge opposite to each other. The third end edge is connected to the second end edge. The plane of the second guide plate 130 is parallel to the plane of the heat dissipation port 110 , that is, the second guide plate 130 extends in the direction of the horizontal plane.

[0042] In this way, by setting up the second guide plate 130, it can be ensured that the airflow passing through the first guide plate 120 can flow toward the rear along the extension direction of the second guide plate 130, while increasing the distance that the high-speed airflow on the lower side of the vehicle bottom guard plate 100 drives the low-speed airflow, thereby increasing the stability of the airflow direction.

[0043] Among them, the fourth end edge is located between the second edge 112 and the first edge 111, that is, the orthographic projections of the first guide plate 120 and the second guide plate 130 on the plane where the heat dissipation port 110 is located are both located in the heat dissipation port 110, and the fourth end edge is located in front of the second edge 112 and on the lower side of the second edge 112. In this way, the high-speed airflow on the lower side of the vehicle bottom guard plate 100 is beneficial to drive the still air on the vehicle bottom guard plate 100, which is beneficial to the flow of gas and the heat dissipation of the device on the upper side of the vehicle bottom guard plate 100.

[0044] At the same time, by arranging the first guide plate 120 and the second guide plate 130 at the first edge 111 , it is possible to effectively prevent gravel and sand from directly rushing into the upper side of the vehicle bottom guard plate 100 and reducing the protective effect of the vehicle bottom guard plate 100 .

[0045] Furthermore, the length of the second guide plate 130 in the front-to-rear direction of the vehicle can be designed according to the specific needs of the vehicle. Specifically, when the heat dissipation demand of the vehicle bottom guard plate 100 is relatively large, the length of the second guide plate 130 in the front-to-rear direction of the vehicle can be selected to be shorter, so that the density of the heat dissipation ports 110 is relatively large. It can be understood that arranging a larger number of heat dissipation ports 110 can bring about better heat dissipation effects; when the heat dissipation demand of the vehicle bottom guard plate 100 is relatively small, the length of the second guide plate 130 in the front-to-rear direction of the vehicle can be selected to be longer, so that the density of the heat dissipation ports 110 is relatively small.

[0046] In some embodiments of this application, please refer to Figure 4 and Figure 5 The vehicle bottom guard plate 100 may further include a third guide plate 140, the third guide plate 140 includes a fifth end side and a sixth end side opposite to each other, the fifth end side is connected to the fourth end side, and the third guide plate 140 extends obliquely toward the ground in the direction from the fifth end side toward the sixth end side. Thus, by providing the third guide plate 140, on the one hand, the airflow is further guided to flow in the obliquely backward direction; on the other hand, the airflow is compressed by the inclined surface, the airflow velocity increases, and the heat dissipation effect of the vehicle bottom guard plate 100 is further improved.

[0047] The sixth end edge is located between the second edge 112 and the first edge 111. In this way, the third guide plate 140 can avoid blocking the heat dissipation port 110, and the sixth end edge is located in front of the second edge 112 and at the lower side of the second edge 112, so that the high-speed airflow at the lower side of the vehicle bottom guard plate 100 can drive the static air on the vehicle bottom guard plate 100, thereby achieving a good heat dissipation effect.

[0048] In some embodiments of this application, please continue to refer to Figure 4 and Figure 5 The vehicle bottom guard plate 100 may further include a fourth guide plate 150, the fourth guide plate 150 includes a seventh end edge and an eighth end edge relative to each other, the seventh end edge is connected to the sixth end edge, and the plane where the fourth guide plate 150 is located is parallel to the plane where the heat dissipation port 110 is located; in this way, by setting the fourth guide plate 150, it can be ensured that the airflow passing through the third guide plate 140 can flow toward the rear along the extension direction of the fourth guide plate 150, and at the same time, the distance that the high-speed airflow on the lower side of the vehicle bottom guard plate 100 drives the low-speed airflow is increased, thereby increasing the stability of the airflow direction.

[0049] The eighth end edge is located between the second edge 112 and the first edge 111. In this way, the fourth guide plate 150 can avoid blocking the heat dissipation port 110, and the eighth end edge is located in front of the second edge 112 and at the lower side of the second edge 112, so that the high-speed airflow at the lower side of the vehicle bottom guard plate 100 can drive the static air on the vehicle bottom guard plate 100, thereby achieving a good heat dissipation effect.

[0050] In some embodiments of this application, please continue to refer to Figure 2 and Figure 3 The heat dissipation vent 110 may further include a third edge 113 and a fourth edge 114 opposite to each other in the left-right direction of the vehicle, and the vehicle bottom guard plate 100 may further include a first connecting plate 160 and a second connecting plate.

[0051] The first connecting plate 160 is located on a side of the heat dissipation port 110 close to the third edge 113, one end of the first connecting plate 160 is connected to the third edge 113, and the other end is connected to the first guide plate 120. The second connecting plate is located on a side of the heat dissipation port 110 close to the fourth edge 114, one end of the second connecting plate is connected to the fourth edge 114, and the other end is connected to the first guide plate 120.

[0052] Therefore, by setting the first connecting plate 160 and the second connecting plate, the gap between the first guide plate 120 and the third edge 113 and the fourth edge 114 is sealed to prevent gas from entering the upper side of the vehicle bottom guard plate 100 from the left and right directions of the first guide plate 120, affecting the flow direction of gas on the upper side of the vehicle bottom guard plate 100, ensuring the stability of the air flow paths on the upper and lower sides of the vehicle bottom guard plate 100, and further ensuring the stability of the heat dissipation effect of the vehicle bottom guard plate 100.

[0053] In some embodiments of this application, please continue to refer to Figure 2 and Figure 3 The vehicle bottom guard plate 100 may further include a third connecting plate 180 and a fourth connecting plate. The third connecting plate 180 is located on a side of the heat dissipation opening 110 close to the third edge 113, and the third connecting plate 180 is respectively connected to the third edge 113, the first connecting plate 160, and the second guide plate 130. The fourth connecting plate is located on a side of the heat dissipation opening 110 close to the fourth edge 114, and the fourth connecting plate is respectively connected to the fourth edge 114, the second connecting plate, and the second guide plate 130.

[0054] Therefore, by setting the third connecting plate 180 and the fourth connecting plate, the gap between the second guide plate 130 and the third edge 113 and the fourth edge 114 is sealed to prevent gas from entering the upper side of the vehicle bottom guard plate 100 from the left and right directions of the second guide plate 130, affecting the flow direction of gas on the upper side of the vehicle bottom guard plate 100, ensuring the stability of the air flow paths on the upper and lower sides of the vehicle bottom guard plate 100, and further ensuring the stability of the heat dissipation effect of the vehicle bottom guard plate 100.

[0055] Furthermore, the third connecting plate 180 may extend to the second edge 112 , and the fourth connecting plate may extend to the second edge 112 , so that airflow from the third edge 113 and the fourth edge 114 into the upper side of the vehicle bottom guard plate 100 may be prevented.

[0056] Understandably, please continue to refer to Figure 4 and Figure 5 When the vehicle bottom guard plate 100 may include the third guide plate 140, the third connecting plate 180 and the fourth connecting plate may also cover the gap between the third guide plate 140 and the third edge 113 and the fourth edge 114. When the vehicle bottom guard plate 100 includes the fourth guide plate 150, the third connecting plate 180 and the fourth connecting plate may also cover the gap between the fourth guide plate 150 and the third edge 113 and the fourth edge 114.
