Description

Technical Field

[0001] This utility model belongs to the field of vehicle parts technology, and in particular relates to a fairing and a vehicle. Background Technology

[0002] The vehicle's air intake grille faces the engine compartment. Current technology often uses a deflector at the rear of the grille to direct cool air to the engine compartment's cooling system. However, this approach has drawbacks. For vehicles with both a cooling system and an engine intake system, a separate intake structure is needed to deliver air from the grille to the engine intake system to ensure proper engine operation. This structure is complex, difficult to assemble, requires more installation space, and is more expensive. Utility Model Content

[0004] In view of the above technical problems, this utility model provides a deflector, including an air inlet, a deflector channel, and an air intake channel, wherein the deflector channel is connected to the air inlet, and the air intake channel is connected between the deflector channel and the engine intake pipe.

[0005] Optionally, the air intake passage is arranged in a circuitous manner between the guide passage and the engine intake pipe.

[0009] Optionally, the air guide includes a first air guide portion connected between the air intake grille and the first heat dissipation structure, and a second air guide portion connected between the first air guide portion and the second heat dissipation structure; the air inlet is disposed on the first air guide portion at a position opposite to the air intake grille; the first channel is disposed on the first air guide portion to connect the air inlet and the first heat dissipation structure; the second channel is disposed on the second air guide portion to connect the first channel and the second heat dissipation structure.

[0010] Optionally, the second flow guide includes a first side plate, a second side plate, and an arc-shaped flow guide plate connected between the first side plate and the second side plate; the first side plate, the second side plate, and the arc-shaped flow guide plate are all connected between the first flow guide and the second heat dissipation structure; the first side plate, the arc-shaped flow guide plate, and the second side plate form the second channel.

[0011] Optionally, in the direction of the air inlet toward the first heat dissipation structure, the cross-sectional area of ​​the first channel gradually decreases.

[0012] Optionally, in the direction from the first heat dissipation structure to the second heat dissipation structure, the cross-sectional area of ​​the second channel gradually decreases; and / or

[0013] In the direction from the air inlet toward the first heat dissipation structure, the cross-sectional area of ​​the second channel gradually increases.

[0014] This utility model also provides a vehicle including the aforementioned fairing.

[0015] In this invention, the air guide includes an air inlet, a flow guide channel, and an air intake channel. The flow guide channel is connected to the air inlet, and the air intake channel is connected between the flow guide channel and the engine air intake pipe.

[0016] In this invention, airflow can smoothly and efficiently enter the guide channel of the shroud from the air inlet, thereby effectively dissipating heat from the device to be cooled (such as a radiator) located at the other end of the guide channel, reducing its temperature. Simultaneously, because an intake channel is provided between the guide channel and the engine intake pipe, some of the airflow within the guide channel will enter the engine intake pipe through the intake channel, ensuring that air can smoothly and efficiently enter the engine combustion chamber, thus meeting the intake requirements of the vehicle engine's intake system.

Detailed Implementation

[0023] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0024] It should be understood that the terms "upper", "lower", "left", "right", "front", "rear", "middle", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations of this utility model.

[0025] like Figures 1 to 3As shown, one embodiment of this utility model provides a diffuser 1, including an air inlet 110, a flow channel 2, and an air intake channel 3. The flow channel 2 connects to the air inlet 110, and the air intake channel 3 connects the flow channel 2 and the engine intake pipe 6. In a specific embodiment, the diffuser 1 is connected between the air intake grille 4 and the heat dissipation device 5 (such as a radiator). The air inlet 110 on the fairing 1 is positioned opposite the air intake grille 4, allowing airflow to smoothly and efficiently enter the fairing 1 from the air intake grille 4 through the air inlet 110. The airflow entering the fairing 1 is guided to the cooling device 5 via the guide channel 2, enabling the cooling device 5 to effectively dissipate heat using cool air and reduce its temperature. The guide channel 2 guides the airflow entering from the air inlet 110 to the cooling device 5 for heat dissipation. Specifically, an intake channel 3 is provided between the guide channel 2 and the engine intake pipe 6. The airflow entering the fairing 1 can also enter the intake channel 3 via the guide channel 2 and flow into the engine intake pipe 6, ensuring that air can smoothly and efficiently enter the engine combustion chamber, thereby meeting the intake requirements of the vehicle engine intake system. Thus, the airflow from the air intake grille 4 into the air intake 110 and into the air guide channel 2 can be guided to the cooling device 5 and the engine intake pipe 6 through two paths respectively, which can not only meet the cooling needs of the cooling device 5, but also take into account the air intake needs of the intake system. The air guide 1 of this embodiment is suitable for vehicles that have both a cooling device 5 (such as a radiator) and an engine, such as hybrid electric vehicles or fuel vehicles.

[0026] In the above embodiments of this utility model, airflow can smoothly and efficiently enter the guide channel 2 of the shroud 1 from the air inlet 110, thereby effectively dissipating heat from the heat-dissipating device 5 (such as a radiator) located at the other end of the guide channel 2, thus reducing the temperature of the heat-dissipating device 5. Simultaneously, since an intake channel 3 is provided between the guide channel 2 and the engine intake pipe 6, some of the airflow in the guide channel 2 will enter the engine intake pipe 6 through the intake channel 3, ensuring that air can smoothly and efficiently enter the engine combustion chamber, thereby meeting the intake requirements of the vehicle engine intake system. This utility model integrates the guide channel 2 and the intake channel 3 on the same shroud 1, simultaneously meeting the heat dissipation requirements of the heat-dissipating device 5 and the intake requirements of the engine system. Furthermore, its structure is simple, assembly is convenient, installation space is reduced, and manufacturing and assembly costs are saved.

[0027] In one embodiment, such as Figure 1 and Figure 3As shown, the air intake channel 3 is arranged in a circuitous manner between the guide channel 2 and the engine intake pipe 6. The specific shape and structure of the circuitous air intake channel 3 can be determined according to requirements and is not limited here, as long as a circuitous air intake channel 3 can be formed, thereby reducing the intrusion of foreign objects such as water and snow particles, and preventing water and snow particles from being transported to the engine intake pipe 6 and causing engine failure. Furthermore, the air intake channel 3 can be a tubular channel to ensure sufficient air intake and prevent insufficient air intake.

[0028] In one embodiment, such as Figure 1 and Figure 3 As shown, the air intake passage 3 includes a first pipe section 310 connecting the guide passage 2, a second pipe section 320 connecting the engine intake pipe 6, and an intermediate pipe section 330 connecting the first pipe section 310 and the second pipe section 320; the intermediate pipe section 330 is set at a first inclination angle to the first pipe section 310; the intermediate pipe section 330 is set at a second inclination angle to the second pipe section 320. Understandably, the first pipe section 310, the intermediate pipe section 330, and the second pipe section 320 are sequentially connected to form the air intake passage 3, which connects the guide passage 2 and the intake pipe 6 to prevent exhaust gas from the engine compartment from flowing back into the engine intake pipe. The first tilt angle and the second tilt angle can be set according to requirements, such as the design requirements of the vehicle model and engine. The setting of the first tilt angle and the second tilt angle can make the air intake channel 3 form a detour structure air intake channel 3. In this way, the amount of foreign objects such as water and snow particles can be reduced through the detour structure air intake channel 3, and water and snow particles can be prevented from being transported to the engine intake pipe 6 and causing engine failure.

[0029] In one embodiment, such as Figure 3 As shown, the inner wall of the air intake passage 3 is provided with multiple baffles 340, which are arranged in an alternating pattern. Specifically, the inner wall of the air intake passage 3 is provided with multiple baffles 340 for blocking foreign objects (such as water and snow particles) from entering the engine air intake pipe 6. The alternating arrangement of the multiple baffles 340 can further block foreign objects such as water and snow particles from intruding into the engine air intake pipe 6, and can also help stabilize the airflow, so that the airflow enters the engine more evenly and improves combustion efficiency.

[0030] In one embodiment, such as Figure 1 and Figure 2As shown, the airflow guiding channel 2 includes a first channel 210 connected to the air inlet 110 and a second channel 220 connected to the first channel 210; the end of the air intake channel 3 away from the engine intake pipe 6 is connected to the first channel 210. That is, the airflow guiding channel 2 includes two branches, and the first channel 210 and the second channel 220 are used to guide the airflow entering from the air inlet 110 to two different heat dissipation structures, thereby performing targeted and rapid heat dissipation on the different heat dissipation structures, thereby improving heat dissipation efficiency; it is understood that the two different heat dissipation structures corresponding to the ends of the first channel 210 and the second channel 220 away from the air inlet can belong to different areas of the same heat dissipation device 5 (such as a radiator), or they can belong to different heat dissipation devices 5, which is not limited here.

[0031] In one embodiment, such as Figures 1 to 2 As shown, the air guide shroud 1 includes a first air guide portion 120 connected between the air intake grille 4 and the first heat dissipation structure, and a second air guide portion 130 connected between the first air guide portion 120 and the second heat dissipation structure; the air inlet 110 is disposed on the first air guide portion 120 at a position opposite to the air intake grille 4; the first channel 210 is disposed on the first air guide portion 120 to connect the air inlet 110 and the first heat dissipation structure; the second channel 220 is disposed on the second air guide portion 130 to connect the first channel 210 and the second heat dissipation structure.

[0032] Specifically, the first channel 210 is disposed on the first guide portion 120 and is used to guide the airflow entering from the air inlet 110 to the first heat dissipation structure; the second channel 220 is disposed on the second guide portion 130 and is used to guide the airflow entering from the air inlet 110 to the first channel 210 to the second heat dissipation structure. The first heat dissipation structure and the second heat dissipation structure can belong to different areas of the same heat dissipation device 5, or they can belong to different heat dissipation devices 5, and this is not limited here. When the first heat dissipation structure and the second heat dissipation structure correspond to different positions of the same heat dissipation device 5, the design of this embodiment can effectively dissipate heat from different positions of the heat dissipation device, thereby improving the overall heat dissipation efficiency of the heat dissipation device 5.

[0033] Understandably, such as Figures 1 to 3As shown, the air deflector 1 includes a first air deflector 120 and a second air deflector 130 connected to the first air deflector 120. The air inlet 110 of the air deflector 1 is disposed on the first air deflector 120, and the air inlet 110 is arranged opposite to the lower grille of the front bumper in the air intake grille 4. That is, the first air deflector 120 is arranged opposite to the lower grille of the front bumper. One end of the second air deflector 130 is connected to the first air deflector 120, and the other end is connected to the second heat dissipation structure. In a specific embodiment, the heat dissipation device 5 includes a first heat dissipation structure and a second heat dissipation structure. The second heat dissipation structure is located above the first heat dissipation structure, and the second heat dissipation structure is arranged opposite to the second air deflector 130. The first heat dissipation structure is arranged opposite to the first air deflector 120. In this utility model, the first heat dissipation structure can refer to the structure corresponding to the lower end after the heat dissipation device 5 is installed on the vehicle, and the second heat dissipation structure can refer to the structure corresponding to the middle and upper end after the heat dissipation device 5 is installed on the vehicle. A first channel 210 is provided on the first airflow guide 120, which is used to guide the airflow entering from the air inlet 110 to the first heat dissipation structure. A second channel 220 is provided on the second airflow guide 130, which is used to guide the airflow entering from the air inlet 110 into the first channel 210 to the second heat dissipation structure. The first channel 210 and the second channel 220 are combined to form the airflow guide channel 2. That is, the airflow entering from the air inlet 110 can be guided to the first heat dissipation structure and the second heat dissipation structure through the first channel 210 and the second channel 220 respectively, thereby improving the heat dissipation efficiency of the heat dissipation device 5.

[0034] In one embodiment, such as Figure 1 As shown, the first airflow guide 120 includes a first airflow guide plate 1210, a first connecting plate 1220, a second airflow guide plate 1230, and a second connecting plate 1240 connected sequentially. The side of the second connecting plate 1240 away from the second airflow guide plate 1230 is connected to the side of the first airflow guide plate 1210 away from the first connecting plate 1220. The first airflow guide plate 1210, the first connecting plate 1220, the second airflow guide plate 1230, and the second connecting plate 1240 form the first channel 210. The air inlet 110 is located at one end of the first channel 210 near the lower grille of the front bumper. It can be understood that the first airflow guide plate 1210, the first connecting plate 1220, the second airflow guide plate 1230, and the second connecting plate 1240 together form the first channel 210 with the air inlet 110, through which airflow can be guided to the first heat dissipation structure.

[0035] In one embodiment, such as Figure 1As shown, in the direction of the air inlet 110 toward the first heat dissipation structure, the cross-sectional area of ​​the first channel 210 gradually decreases. Understandably, both the first guide plate 1210 and the second guide plate 1230 are inclined so that the projected width of the first channel 210 on the second connecting plate 1240 gradually decreases from the air inlet 110 toward the heat dissipation device 5. That is, the first guide plate 1210 and the second guide plate 1230 are arranged in a trumpet shape on opposite sides of the first connecting plate 1210 and the second connecting plate 1240, thereby better guiding the airflow entering through the air inlet 110 to the heat dissipation device 5 and improving heat dissipation efficiency.

[0036] In one embodiment, such as Figure 1 As shown, the first airflow guide 120 further includes a connector 1250, which is connected between the first connecting plate 1220 and the second connecting plate 1240. The connector 1250 is used to divide the air inlet 110 into a first air inlet 1110 and a second air inlet 1120. Understandably, the connector 1250 is connected between the first connecting plate 1220 and the second connecting plate 1240, thus dividing the air inlet 110 into a first air inlet 1110 and a second air inlet 1120. The first air inlet 1110 is opposite to the left side of the air intake grille 4, and the second air inlet 1120 is opposite to the right side of the air intake grille 4, to meet the requirements of vehicle design. Understandably, the length and shape of the connector 1250 extending toward the first heat dissipation structure can be set according to requirements. In some embodiments, a longer connector 1250 can be used to divide the first channel 210 into two channels corresponding to the first air inlet 1110 and the second air inlet 1120 respectively, thereby guiding the cold air entering through the first air inlet 1110 and the second air inlet 1120 to the first heat dissipation structure in an orderly manner, which can further improve the heat dissipation efficiency.

[0037] In one embodiment, such as Figure 1 and Figure 2As shown, the second flow guide 130 includes a first side plate 1310, a second side plate 1320, and an arc-shaped flow guide plate 1330 connected between the first side plate 1310 and the second side plate 1320; the first side plate 1310, the second side plate 1320 and the arc-shaped flow guide plate 1330 are all connected between the first flow guide 120 and the second heat dissipation structure; the first side plate 1310, the arc-shaped flow guide plate 1330 and the second side plate 1320 form the second channel 220. Understandably, the first side plate 1310, the arc-shaped guide plate 1330, and the second side plate 1320 of the second guide section 130 form a second channel 220, thereby allowing the airflow in the first channel 210 to be guided to the second heat dissipation structure via the second channel 220. Thus, when the first heat dissipation structure and the second heat dissipation structure correspond to the lower end and upper-middle end of the device to be cooled, respectively, the design of this embodiment can effectively dissipate heat from the first heat dissipation structure and the second heat dissipation structure of the device to be cooled, thereby improving the overall heat dissipation efficiency of the device to be cooled. Understandably, the arc-shaped guide plate 1330 can be configured according to requirements. For example, the arc shape of the arc-shaped guide plate 1330 can be a circular arc plate, an irregular arc plate, or a straight plate inclined between the first guide section 120 and the second heat dissipation structure, as long as it can guide the airflow from the first channel 210 through the second channel 220 to be deflected and split, thereby changing the fluid direction and speed, so that it can be smoothly guided from the second channel 220 to the second heat dissipation structure.

[0038] In one embodiment, such as Figure 2 As shown, in the direction from the first heat dissipation structure to the second heat dissipation structure, the cross-sectional area of ​​the second channel 220 gradually decreases. That is, in the direction from the first heat dissipation structure to the second heat dissipation structure, the arc-shaped guide plate 1330 is inclined and gradually approaches the second heat dissipation structure, thereby guiding the airflow from the first channel 210 to the position in the second heat dissipation structure where it finally contacts the arc-shaped guide plate 1330, thereby improving the heat dissipation efficiency.

[0039] In one embodiment, such as Figure 2 As shown, in the direction from the air inlet 110 toward the heat dissipation device 5, the cross-sectional area of ​​the second channel 220 gradually increases. That is, in the direction from the air inlet 110 toward the heat dissipation device 5, the projected area of ​​the arc-shaped guide plate 1330 on the second heat dissipation structure gradually increases. This means that the coverage area of ​​the arc-shaped guide plate 1330 on the second heat dissipation structure gradually increases, thereby increasing the coverage area of ​​the airflow from the first channel 210 through the second channel 220 to the second heat dissipation structure, which can further improve the heat dissipation efficiency.

[0040] In one embodiment, the air deflector 1 further includes a first sealing element (not shown) sealingly connected between the air deflector 1 and the air intake grille 4, and a second sealing element (not shown) sealingly connected between the air deflector 1 and the heat dissipation device 5. Understandably, the first sealing element effectively fills the gap between the air deflector 1 and the air intake grille 4, preventing external substances such as air, dust, and moisture from entering the airflow channel 2, thereby maintaining the cleanliness and stability of the internal environment of the airflow channel 2. The function of the second sealing element is similar to that of the first sealing element and will not be described again. Furthermore, the first and second sealing elements can be sealing foam, or sealing elements made of other materials such as rubber, silicone, or rubber composite materials, as long as they meet their sealing requirements.

[0041] This utility model also provides a vehicle including the aforementioned fairing 1. In the vehicle of the above embodiment of this utility model, airflow can smoothly and efficiently enter the guide channel 2 of the fairing 1 from the air inlet 110, thereby effectively cooling the heat dissipation device 5 (such as a radiator) located at the other end of the guide channel 2, reducing the temperature of the heat dissipation device 5; at the same time, since an intake channel 3 is provided between the guide channel 2 and the engine intake pipe 6, part of the airflow in the guide channel 2 will enter the engine intake pipe 6 through the intake channel 3, thereby ensuring that air can smoothly and efficiently enter the engine combustion chamber, thus meeting the intake requirements of the vehicle engine intake system. This utility model integrates the guide channel 2 and the intake channel 3 on the same fairing 1, which can simultaneously meet the heat dissipation requirements of the heat dissipation device 5 and the intake requirements of the engine system, and its structure is simple, easy to assemble, reduces installation space, and saves manufacturing and assembly costs.

[0042] The above are merely embodiments of the fairing 1 and the vehicle of this utility model, and are not intended to limit this utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
