Description

Technical Field

[0001] This application relates to the field of vehicle component technology, specifically to a wind deflector water-blocking structure and a vehicle. Background Technology

[0002] To reduce wind resistance, new energy hybrid vehicles typically feature small air intakes in the front bumper, with air ducts guiding airflow to the radiator for cooling. However, new energy hybrid vehicles often experience prolonged idling charging, generating significant heat in the engine compartment. This causes a rapid increase in cabin air temperature, and the recirculation of this hot air further raises the engine intake temperature, ultimately affecting engine performance and idling charging efficiency.

[0003] To address these issues, existing technology places the engine air intake inside the air deflector to prevent the backflow of hot air from affecting engine performance. However, this design introduces new technical problems when the vehicle is designed to meet wading depth requirements: in wading conditions, water can enter between the air deflector and the radiator through the front bumper's air intake. Due to the impact, the water cannot be quickly expelled from between the radiator fins, and after impacting the radiator, it surges upwards to the engine air intake above the air deflector. When the engine is running, the negative pressure of the intake air will draw the surging water into the engine, causing water ingress, damaging engine components, shortening their lifespan, and even causing the engine to lose power, posing a serious safety hazard. Utility Model Content

[0004] In view of this, the purpose of this application is to provide a wind deflector structure and a vehicle to solve at least one of the above-mentioned technical problems.

Where there is no conflict, the embodiments and features described in these embodiments can be combined in a suitable manner.

[0034] Figure 1 This is a schematic diagram of a wind deflector and water-blocking structure 100 provided in an embodiment of this application. Figure 2 This is an exploded structural diagram of a wind deflector and water-blocking structure 100 provided in an embodiment of this application, as shown below. Figure 1 and Figure 2 As shown in the figure, this application embodiment provides a wind deflector water-blocking structure 100, including a wind deflector 10 and a water-blocking component 20.

[0035] The air deflector 10 is positioned between the air intake and the radiator at the front of the vehicle to guide the airflow from the front of the vehicle toward the radiator, thereby accelerating radiator cooling. The air deflector 10 has a front port for connecting to the air intake and a rear port for connecting to the radiator. The top of the rear port of the air deflector 10 is also provided with an engine air intake 131, which is used for engine air intake to prevent the backflow of high-temperature air from the engine compartment from affecting engine performance.

[0036] As an example, the air duct 10 includes a first air duct 11, a second air duct 12, and a third air duct 13. The first air duct 11 forms a first air duct extending along the length of the vehicle. The front end of the first air duct 11 is connected to the main air intake below the front bumper of the vehicle, and the rear end of the first air duct 11 is connected to the third air duct 13. The second air duct 12 is disposed above the first air duct 11 and forms a second air duct extending along the length of the vehicle. The front end of the second air duct 12 is connected to an auxiliary air intake on the front bumper of the vehicle, and the rear end of the second air duct 12 is connected to the third air duct 13. The third air duct 13 is connected to the front side of the radiator 200 and forms a rectangular air duct cavity extending along the width and height of the vehicle. The top sidewall of the third air duct 13 has an engine air intake 131 extending along the width of the vehicle.

[0037] The first air guide 11 and the third air guide 13 can be integrally formed or connected separately, and the second air guide 12 and the third air guide 13 can be integrally formed or connected separately. As an example, the first air guide 11 and the third air guide 13 are integrally formed, and the second air guide 12 and the third air guide 13 are connected by a slot and a buckle.

[0038] likeFigure 1 and Figure 2 As shown, the water deflector 20 is installed in the engine air intake 131 and located inside the air guide shroud 10. The water deflector 20 is used to block the water flow towards the engine air intake 131 when the vehicle is wading through water, while ensuring the engine intake.

[0039] As an example, such as Figure 3 and Figure 4 As shown, the water-blocking component 20 has a hollow structure and includes a mounting surface 21, a stop surface 22, and a sidewall connecting the mounting surface 21 and the stop surface 22. The mounting surface 21 of the water-blocking component 20 is an open structure and flush with the engine air intake 131. The edge of the mounting surface 21 has an outwardly bent flange 23, which is used to overlap and fit with the edge of the engine air intake 131. The stop surface 22 of the water-blocking component 20 is used to block the water flow when the vehicle is wading through water. The stop surface 22 is located inside the air guide shroud 10 and faces the air intake direction of the engine air intake 131. Depending on the direction of air flow from the air guide shroud 10 to the engine air intake 131, the stop surface 22 can be arranged parallel to the mounting surface 21 or at a certain angle. In this embodiment, the stop surface 22 is parallel to the mounting surface 21. The size of the stop surface 22 can be slightly smaller than the size of the mounting surface 21, so that the water baffle 20 has a structure that tapers inward from the mounting surface 21 towards the stop surface 22, which facilitates the insertion and assembly of the water baffle 20 into the engine air intake 131. Of course, the size of the stop surface 22 can also be equal to the size of the mounting surface 21. The side wall of the water baffle 20 has multiple side openings 24 for engine air intake, and the side openings 24 are connected to the internal space of the water baffle 20 and the openings of the mounting surface 21. The water baffle 20 shown in the figure is approximately rectangular box-shaped with four side walls, each of which has at least one side opening 24, and the shape of the side opening 24 is not limited.

[0040] The water-blocking component 20 can be connected to the air guide cover 10 by snap-fit, adhesive, screw, or other connection methods.

[0041] As an example, in addition to the flange 23, the edge of the mounting surface 21 also has multiple first clips 25. These first clips 25 cooperate with the flange 23 to lock the edge of the engine air intake 131 from the inside and outside, respectively, to achieve engagement with the air guide shroud 10. This connection structure is simple, reliable, easy to install and disassemble, requires no tools or connectors, and is low in cost. The figure shows four first clips 25, with two first clips 25 on each of the two long edges of the mounting surface 21 of the water baffle 20. The connection between each first clip 25 and the edge of the mounting surface 21 can be thickened to ensure sufficient lever strength when the first clip 25 is engaged; the thickened area can be seen at mark A in the figure.

[0042] Furthermore, multiple second clips 26 are distributed along the edge of the mounting surface 21. These second clips 26 abut against the edge of the engine air intake 131, which can enhance the stability of the connection between the water deflector 20 and the air guide shroud 10. The figure shows two second clips 26, with one second clip 26 on each of the two short edges of the mounting surface 21 of the water deflector 20.

[0043] The stop surface 22 of the water-blocking component 20 can be a continuous surface, meaning that the stop surface 22 continuously covers the entire bottom area of ​​the water-blocking component 20, forming a complete surface. Alternatively, the stop surface 22 of the water-blocking component 20 can be a segmented structure, consisting of multiple stop segments with gaps between adjacent segments. These gaps allow air to enter, improving air intake efficiency. The dimensions of each stop segment and the size of the gaps can be optimized according to the vehicle's wading design requirements and the engine's air intake needs, maximizing engine air intake efficiency while ensuring the water-blocking effect.

[0044] The sidewall of the water baffle 20 can be configured according to the stop surface 22. When the stop surface 22 is a continuous surface, the sidewall forms a continuous structure; when the stop surface 22 is a segmented structure, the sidewall also adopts a segmented structure, including multiple sidewall segments corresponding to the stop segment of the stop surface 22, and gaps are formed between adjacent sidewall segments, which can increase the air intake area and improve the air intake efficiency.

[0045] Regarding the case where the stop surface 22 of the water-blocking component 20 is a continuous surface and the side wall forms a continuous structure, the water-blocking component 20 has a complete box-shaped structure, which will not be elaborated here.

[0046] Regarding the case where the stop surface 22 of the water-blocking component 20 has a segmented structure and the sidewall is correspondingly divided into multiple sidewall segments, as an example, such as... Figure 3 and Figure 4 As shown, the water baffle 20 is divided into five parts along its length (i.e., the extension direction of the engine air intake 131). The edges of the mounting surfaces 21 of these five parts are connected as one piece, and the stop surfaces 22 of the five parts are separate from the side walls. Specifically, the five parts include a first part 27, two second parts 28, and two third parts 29. The first part 27 is located at the middle of the length of the water-blocking member 20. The first part 27 is box-shaped with four side walls and side openings 24 on each of the four side walls. The two second parts 28 are located at the two ends of the length of the water-blocking member 20. Each second part 28 is box-shaped with four side walls and side openings 24 on each of the four side walls. The length of the second part 28 is less than the length of the first part 27. A third part 29 is provided in the gap between each second part 28 and the first part 27. Each third part 29 is box-shaped with four side walls and side openings 24 on the two side walls corresponding to the length of the water-blocking member 20. The length, width and height of the third part 29 are all smaller than those of the second part 28.

[0047] It should be noted that those skilled in the art can divide the water-blocking component 20 into more or fewer parts according to design needs, and the size and gap of each part can also be adjusted according to design needs.

[0048] This application also provides a vehicle that includes the above-described wind deflector water-blocking structure 100.

[0049] As an example, such as Figures 5 to 8 As shown, the wind deflector structure 100 is installed in the engine compartment at the front of the vehicle. The front port of the wind deflector 10 is connected to the air inlet at the front of the vehicle, and the rear port of the wind deflector 10 is connected to the radiator 200. The upper side of the wind deflector 10 is the front module 300 of the vehicle body structure. The front module 300 integrates the engine air intake channel. The front end of the engine air intake channel is connected to the engine air intake port 131 of the wind deflector 10, and the rear end is connected to the engine air intake pipe 400. The engine air intake pipe 400 is connected to the engine.

[0050] When the vehicle is wading through water, the water flows in from the front port of the air deflector 10 and impacts the radiator 200. Then, it flows up along the air deflector cavity formed between the rear port of the air deflector 10 and the radiator 200 to the engine air intake 131. Since the engine air intake is equipped with a water baffle 20, the water flow will be blocked by the stop surface 22 of the water baffle 20 and will not be sucked into the engine by negative pressure. At the same time, air can enter from the side opening 24 of the water baffle 20 to meet the engine's air intake requirements.

[0051] In summary, the wind deflector water-blocking structure and vehicle provided in this application embodiment, by setting a water-blocking component at the engine air intake of the wind deflector, has a simple structure and is easy to assemble. This water-blocking component can block the water flow towards the engine air intake when the vehicle is wading through water, improving the engine's wading safety, while not affecting engine air intake and ensuring engine power. This wind deflector water-blocking structure is particularly suitable for new energy hybrid vehicles.

[0052] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this application, and these should all be included within the scope of protection of this application.
