Description

Technical Field

[0001] This application relates to the field of automotive technology, and more specifically, to a flow guide structure and a vehicle. Background Technology

[0002] A vehicle fairing is a key component integrating aerodynamics, safety, and economy. Functionally, it significantly reduces wind resistance by optimizing airflow between the front and the cargo box; from a safety perspective, it reduces airflow turbulence at high speeds, enhancing driving stability, especially in crosswind conditions; economically, it effectively reduces operating costs; and environmentally, it helps vehicles meet increasingly stringent emission and energy efficiency standards. Therefore, equipping vehicles with fairings has become an inevitable choice and standard configuration for achieving efficient, safe, and green transportation.

[0003] The existing fairing is located on top of the vehicle's cab, with the heat dissipation structure positioned between the fairing and the cab. To avoid compromising the fairing's ability to reduce wind resistance, the heat dissipation structure is not higher than the fairing. This arrangement causes airflow to pass through the fairing and run along the top of the cab, reducing the heat dissipation effect of the structure. Utility Model Content

[0019] One aspect of the embodiments of this application, such as Figures 1 to 5As shown, a flow guiding structure 100 is provided and disposed on a vehicle body 200. It includes a radiator 110 and a flow guide shroud 120 having an inner cavity 121. The radiator 110 and the flow guide shroud 120 are connected along the traveling direction of the vehicle body 200. The flow guide shroud 120 has an opening 122. A flow guide plate 123 and a driving member 124 drivenly connected to the flow guide plate 123 are provided at the opening 122. The driving member 124 drives the flow guide plate 123 to open and close the opening 122. The opening 122 forms a heat dissipation channel to the radiator 110 through the inner cavity 121.

[0020] Specifically, the airflow guiding structure 100 includes a radiator 110 and a fairing 120. The radiator 110 is used to reduce the temperature of the battery pack and is positioned between the fairing 120 and the vehicle compartment. The fairing 120 guides airflow through the front of the vehicle and away from the vehicle compartment, reducing wind resistance during vehicle operation. The fairing 120 is located on the top of the cab. The fairing 120 has an inner cavity 121 and a through opening. The radiator 110 and the fairing 120 are connected along the travel direction of the vehicle body 200 via the through opening. Figure 2 and Figure 3 The arrow at point A indicates the direction of travel of the vehicle body 200. The fairing 120 also has an opening 122, at which a guide plate 123 and a drive member 124 are provided. The guide plate 123 and the drive member 124 are drivenly connected, and the drive member 124 drives the guide plate 123 to open or close the opening 122. The opening 122 forms a heat dissipation channel to the radiator 110 through the inner cavity 121.

[0021] When a vehicle is driving normally on a level road, such as Figure 2 and Figure 4 As shown, the drive unit 124 drives the deflector 123 to close the opening 122. The deflector 123 has an arc surface and protrudes outward from the inner cavity 121. Guided by the deflector 123, the airflow passes from the top of the shroud 120, over the top of the radiator 110, and finally flows away from the top of the vehicle body, reducing wind resistance during vehicle operation. At this time, the heat in the radiator 110, after heat exchange, forms a hot airflow that flows out from the top of the radiator 110. The airflow guided by the deflector 123 carries away the hot airflow emitted from the radiator 110. In this state, the radiator 110 emits relatively little heat, and the hot airflow is passively carried away by the airflow guided by the deflector 123. When the vehicle is climbing a hill or under heavy load, the radiator 110 emits more heat, such as... Figure 3 and Figure 5As shown, the drive unit 124 drives the guide plate 123 to open the opening 122. At this time, the airflow flowing towards the vehicle enters the inner cavity 121 through the opening 122, and then flows to the radiator 110 through the through-hole. That is, the airflow flows to the radiator 110 through the heat dissipation channel. The airflow flowing through the radiator 110 accelerates the heat exchange rate of the radiator 110. After the airflow flows through the radiator 110, it flows out from the top of the radiator 110, which accelerates the heat dissipation rate of the radiator 110.

[0022] In some embodiments, the drive element 124 may be an electric actuator, a pneumatic cylinder, or a hydraulic cylinder, and there is no limitation on this.

[0023] In some implementations, the number of drive components 124 is at least one, for example, two, three, four or more. The specific number can be set according to the actual situation and is not limited here.

[0024] Optionally, such as Figure 3 As shown, the deflector 123 includes a rotating end 1231 and a free end 1232, which are arranged in sequence along the travel direction of the vehicle body 200. The deflector 123 is rotatably connected to the opening 122 of the deflector 120 via the rotating end 1231.

[0025] Specifically, the deflector 123 includes a rotating end 1231 and a free end 1232, which are arranged opposite to each other. The rotating end 1231 is the end of the deflector 123 that is rotatably connected to the deflector 120, and the free end 1232 is the end of the deflector 123 that is driven away from or closer to the deflector 120 by the driving member 124. The free end 1232 and the rotating end 1231 are arranged sequentially along the travel direction of the vehicle body 200, as follows: Figure 3 The arrow at point A indicates the direction of travel of the vehicle body 200, meaning that the rotating end 1231 is located in front of the free end 1232 along the direction of travel of the vehicle body 200. The driving component 124 includes a movable end and a fixed end. For example, the movable end is movably connected to one side of the guide plate 123 near the inner cavity 121, and the fixed end is fixedly connected to the bottom wall 1211 of the inner cavity 121. The guide plate 123 is driven to rotate towards the inner cavity 121 by the driving component 124, causing the free end 1232 to rotate away from the opening 122 and towards the bottom wall 1211 of the inner cavity 121. The positional arrangement of the rotating end 1231 and the free end 1232 of the guide plate 123 ensures the stability of the guide plate 123 when closing the opening 122 during vehicle operation; on the other hand, when the guide plate 123 opens the opening 122, it guides the airflow through the heat dissipation channel to the radiator 110.

[0026] In some embodiments, the deflector 123 and the deflector 120 can be rotatably connected by a hinge, for example by a hinge.

[0027] Optionally, such as Figure 1 As shown, the flow guiding structure 100 also includes a buffer 130, and the flow guiding cover 120 is connected to the heat sink 110 via the buffer 130.

[0028] Specifically, the fairing 120 and the radiator 110 are connected by a buffer 130. During vehicle operation, the buffer 130 prevents the fairing 120 and the radiator 110 from colliding. At the same time, the buffer 130 ensures the sealing of the fairing 120 and the radiator 110 at the connection point.

[0029] In some embodiments, the buffer 130 may be an accordion rubber belt or a structure with the same function, and there is no limitation on this.

[0030] Optionally, such as Figure 3 and Figure 5 As shown, the airflow guiding structure 100 also includes a dustproof net 140, which is located at the connection between the airflow guide shroud 120 and the radiator 110.

[0031] Specifically, when the drive component 124 drives the guide plate 123 to open the opening 122, the airflow flows through the heat dissipation channel to the radiator 110. The airflow contains dust. By setting a dustproof net 140 at the connection between the guide shroud 120 and the radiator 110, the dust in the airflow can adhere to the dustproof net 140, preventing dust from entering the radiator 110.

[0032] In some implementations, the dustproof net 140 can be a flat net or a multi-layer composite net, and there is no limitation on this. Optionally, such as Figure 3 and Figure 5 As shown, the flow guiding structure 100 also includes a dust collection trough 150 and a drain pipe 160. The dust collection trough 150 is connected to the inner cavity 121, and the bottom of the dust collection trough 150 is connected to the drain pipe 160. The dust collection trough 150 is located at the connection between the flow guiding cover 120 and the radiator 110.

[0033] Specifically, the airflow guiding structure 100 also includes a dust collection trough 150 located at the connection between the airflow guide 120 and the radiator 110. The dust collection trough 150 is connected to the inner cavity 121 of the airflow guide 120, and the end of the dust collection trough 150 away from the inner cavity 121 is connected to a drain pipe 160, meaning the bottom of the dust collection trough 150 is connected to the drain pipe 160. When the airflow guide 120 opens its opening 122, rainwater and dust in the airflow enter the inner cavity 121 through the opening 122. Rainwater flows through the inner cavity 121 to the dust collection trough 150 and is then discharged outside the vehicle through the drain pipe 160 connected to the dust collection trough 150. Some dust in the airflow is absorbed by the dustproof net 140, and some dust falls into the dust collection trough 150 and is then discharged outside the vehicle through the drain pipe 160. The dust collection trough 150 and the drain pipe 160 prevent rainwater and dust from remaining inside the airflow guiding structure 100, thus improving the service life of the airflow guiding structure 100.

[0034] Optionally, such as Figure 5 As shown, the cross-sectional area of ​​the dust collection trough 150 gradually decreases from the trough opening to the trough bottom.

[0035] Specifically, the opening of the integrated dust collection trough 150 is the end near the inner cavity 121, and the bottom is the end near the drain pipe 160. The cross-sectional area of ​​the dust collection trough 150 gradually decreases from the opening to the bottom, meaning that the cross-section of the dust collection trough 150 adopts a shape that is wider at the top and narrower at the bottom, such as an inverted trapezoid. When dust falls onto the side wall of the dust collection trough 150, due to its own weight and external vibrations (such as the vibration of a vehicle during driving), the dust will slide down the side wall of the dust collection trough 150 to the bottom, preventing dust from accumulating inside the dust collection trough 150.

[0036] Optionally, such as Figure 3 and Figure 5 As shown, the dustproof net 140 and the dust collection trough 150 are arranged sequentially along the traveling direction of the vehicle body 200, and the dust collection trough 150 is set close to the dustproof net 140.

[0037] Specifically, the dust filter 140 is positioned near the radiator 110, and the dust collection trough 150 is positioned near the air deflector 120, with the dust collection trough 150 close to the dust filter 140. When dust in the airflow is blocked by the dust filter 140, some dust is adsorbed by the dust filter 140, while some dust falls after being blocked. The dust filter 140 and the dust collection trough 150 are arranged sequentially along the travel direction of the vehicle body 200, as shown below. Figure 3 The arrow at point A indicates the direction of travel of the vehicle body 200. The falling dust will fall into the dust collection tank 150 and then be discharged outside the vehicle through the drain pipe 160 at the bottom of the dust collection tank 150.

[0038] Optionally, such as Figure 3As shown, the bottom wall 1211 of the inner cavity 121 is an inclined wall surface, which extends to the opening of the dust collection groove 150, and the inclined wall surface gradually rises along the travel direction of the vehicle body 200.

[0039] Specifically, the bottom wall 1211 of the inner cavity 121 of the fairing 120 is an inclined wall. The inclined wall extends from the rotatable connection between the guide plate 123 and the fairing 120 to the opening of the dust collection trough 150, and the inclined wall gradually rises along the travel direction of the vehicle body 200. That is to say, the end of the inclined wall near the dust collection trough 150 is lower than the end of the inclined wall near the rotatable connection between the guide plate 123 and the fairing 120. When the guide plate 123 opens the opening 122, rainwater enters the inner cavity 121 through the opening 122. Guided by the arc surface of the guide plate 123, the rainwater flows to the bottom wall 1211 of the inner cavity 121. By setting the bottom wall 1211 as an inclined wall, the rainwater flows to the dust collection trough 150 through the inclined wall and is then discharged to the outside of the vehicle through the drain pipe 160. The sloping wall prevents rainwater from accumulating inside the fairing 120, thus extending the service life of the fairing 120.

[0040] Optionally, such as Figure 3 As shown, the flow guiding structure 100 also includes a temperature sensor and a controller. The temperature sensor and the drive unit 124 are electrically connected to the controller. The temperature sensor is used to detect the temperature of the coolant, and the controller controls the drive unit 124 to drive the flow guiding plate 123 according to the temperature of the coolant. Specifically, the flow guiding structure 100 also includes a temperature sensor and a controller. The temperature sensor detects the temperature of the coolant, and the controller controls the drive unit 124 to open or close the flow guide plate 123 based on the coolant temperature. The coolant's workflow is as follows: the coolant flows through the battery pack to carry away the heat dissipated by the battery pack. As the coolant temperature rises, it flows to the radiator 110. After being cooled by the radiator 110, the coolant temperature decreases and it flows back to the battery pack. When the temperature sensor detects an increase in the temperature of the coolant flowing to the radiator 110, the controller controls the drive unit 124 to open the flow guide plate 123. When the temperature sensor detects a decrease in the temperature of the coolant flowing to the radiator 110, the controller controls the drive unit 124 to close the flow guide plate 123.

[0041] In some embodiments, the controller can control the opening angle of the drive member 124 to drive the guide plate 123 according to the temperature of the coolant. When the temperature sensor detects that the temperature of the coolant flowing to the radiator 110 is gradually increasing, the controller can control the drive member 124 to drive the guide plate 123 to gradually increase the opening angle; conversely, when the temperature sensor detects that the temperature of the coolant flowing to the radiator 110 is gradually decreasing, the controller can control the drive member 124 to drive the guide plate 123 to gradually decrease the opening angle.

[0042] In another aspect of this application, a vehicle is provided, including a vehicle body 200 and the aforementioned airflow guiding structure 100, wherein the airflow guiding structure 100 is fixedly disposed on the vehicle body 200.

[0043] Specifically, the vehicle includes a body 200 and a flow guide structure 100 fixedly mounted on the body 200. A drive unit 124 drives a flow guide plate 123 to open an opening 122. Airflow towards the vehicle flows through a heat dissipation channel to the radiator 110. The airflow passing through the radiator 110 accelerates the heat exchange rate of the radiator 110. After passing through the radiator 110, the airflow exits from the top of the radiator 110, further accelerating the heat dissipation rate of the radiator 110 and improving the vehicle's service life.

[0044] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
