[0021] The technical solutions in the embodiments (or "implementations") of this application will be clearly and completely described herein with reference to the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0022] If the embodiments of this application contain terms relating to directional indications or positional relationships (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships and movements between components in a specific posture (as shown in the attached figures); if the specific posture changes, the directional indications or positional relationships will also change accordingly. Furthermore, the terms "first" and "second" used in the embodiments of this application are only for descriptive convenience and should not be construed as indicating or implying relative importance.

[0023] See Figures 1 to 2 As shown, this application provides an engine intake structure, including a front grille (not shown), a radiator upper crossbeam (not shown), an engine cover 10, an air filter 20, and a seal 30. The front grille and the radiator upper crossbeam are located below the engine cover 10 and near the front side of the engine cover 10. The air filter 20 is located below the engine cover 10 and near the center of the engine cover 10. The seal 30 is located on the inner side of the engine cover 10.

[0024] Please also see Figure 3 As shown, the engine hood 10 has an internal cavity 101 located above the upper crossbeam of the radiator, raising the air intake height and preventing water from directly entering the engine when the vehicle is wading through low-lying water. The cavity 101 includes multiple air inlets 11 and outlets 12 on the engine hood 10. Both the air inlets 11 and outlets 12 are connected to the cavity 101. The outlets 12 are connected to the air filter 20. The cavity 101 acts as an air passage, raising the air intake path to inside the engine hood 10, ensuring that air flows into the air filter 20 from above the upper crossbeam of the radiator.

[0025] Multiple air intakes 11 include a first air intake 111 and a second air intake 112. The arrangement of two air intakes provides redundant air intake channels; when water enters one intake, the other intake can maintain air intake, dispersing the risk of water ingress and ensuring stable engine operation when wading. The first air intake 111 is connected to the upper crossbeam of the radiator. The upper crossbeam guides air into the first air intake 111, ensuring efficient air intake for the engine during normal driving. The first air intake 111 is located above and directly opposite the upper crossbeam of the radiator, optimizing the straight flow of airflow, reducing turbulence losses, and ensuring efficient air transfer to the cavity 101. The front grille is connected to the upper crossbeam of the radiator. The front grille, upper crossbeam of the radiator, first air intake 111, cavity 101, and exhaust 12 are sequentially connected to form the first air intake channel.

[0026] There are two first air inlets 111, which are located on the front side of the engine hatch cover 10. The two first air inlets 111 are symmetrically arranged with respect to the central axis of the engine hatch cover 10 along the width direction of the engine hatch cover 10.

[0027] A headlight (not shown) is located below the hood 10, and there is a gap (not shown) between the headlight and the edge of the hood 10. The second air intake 112 communicates with the gap. The gap, the second air intake 112, the cavity 101, and the air outlet 12 are sequentially connected to form a second air intake passage. The height of the second air intake 112 is higher than the height of the first air intake 111. The second air intake passage provides a backup air intake passage when the vehicle is wading through deep water. The gap serves as the air inlet point. When the crossbeam above the radiator is wading through water, the engine receives air through the second air intake passage.

[0028] According to the embodiments of this application, the height of the air outlet 12 is greater than the height of the air inlet 11. Specifically, the height of the air outlet 12 is higher than the height of the first air inlet 111 and the second air inlet 112. In the embodiments of this application, the height of the second air inlet 112 is 26mm to 42mm higher than the height of the first air inlet 111, and the height of the air outlet 12 is 43mm to 56mm higher than the height of the first air inlet 111. The diameter of the first air inlet 111 is larger than the diameter of the second air inlet 112.

[0029] The engine compartment cover 10 includes an inner panel 13 and an outer panel 14 connected together. The inner panel 13 and the outer panel 14 together form a cavity 101. The inner panel 13 and the outer panel 14 are made of sheet metal. The first air inlet 111, the second air inlet 112, and the air outlet 12 are all located on the inner panel 13.

[0030] The air filter 20 includes a filter body 21 and an intake pipe 22 and an outlet pipe 23 disposed on the filter body 21. The two ends of the intake pipe 22 are connected to the outlet 12 and the filter body 21, respectively. One end of the intake pipe 22 is provided with a rubber hose 221, which is disposed inside the outlet 12 and communicates with the cavity 101. The rubber hose 221 provides a dynamic seal to accommodate thermal expansion and contraction, and can compensate for installation tolerances, improving airtightness and preventing air leakage. The two ends of the outlet pipe 23 are connected to the filter body 21 and the engine (not shown), respectively. Air enters the engine through the outlet 12, the intake pipe 22, the filter body 21, and the outlet pipe 23.

[0031] According to the embodiments of this application, the exhaust pipe 23 is a flexible hose, and an intake valve can be provided on the exhaust pipe 23 to regulate the flow rate of gas flowing into the engine through the filter body 21.

[0032] The engine cover 10 covers the front compartment of the vehicle (not shown), and the air filter 20 and engine are located inside the front compartment. A seal 30 is provided around the air intake 11. Specifically, the seal 30 is provided around the perimeter of both first air intakes 111 and the second air intake 112. The seal 30 is used to seal the gap between the engine cover 10 and the upper crossbeam of the radiator. Specifically, the seal 30, the engine cover 10, and the upper crossbeam of the radiator together form an air intake chamber located between the upper crossbeam of the radiator and the first air intake 111. The air intake chamber is separated from the front compartment of the vehicle by the seal 30, preventing hot air or moisture from the front compartment from entering the first air intake 111.

[0033] According to an embodiment of this application, a sealing element 30 is also provided on the inner side of the second air intake 112 to separate the vehicle's front compartment from the second air intake 112 and prevent hot air from the vehicle's front compartment from entering the second air intake 112. In an embodiment of this application, the sealing element 30 is a sealing strip. Alternatively, the sealing element 30 may also be silicone or a sponge pad.

[0034] According to an embodiment of this application, the headlights include left and right headlights located on both sides of the vehicle, with a gap between the left and right headlights and the edge of the hood 10, and the gap between the left and right headlights and the edge of the hood 10 not sealed by the air self-sealing component 30 (e.g. Figure 2 (As indicated by the arrow) Enters the second air intake 112.

[0035] In the embodiments of this application, the gap between the unsealed left and right headlights and the edge of the engine compartment cover 10 can also be connected to the two first air inlets 111 to increase the air intake volume of the first air inlets 111.

[0036] This application provides two first air inlets 111 on the inner plate 13 of the engine hood 10, and a ring of seals 30 is fixed around the two first air inlets 111. The seals 30 seal the gap between the engine hood 10 and the upper crossbeam of the water tank, preventing hot air from the front compartment of the vehicle from entering the first air inlets 111. Fresh air enters the first air inlets 111 from the front grille through the upper crossbeam of the water tank, passes through the cavity 101 to the air outlet 12 at a higher position above the ground, and then enters the engine through the air filter 20, effectively preventing water from entering the engine. Increasing the height of the first air inlets 111 improves the vehicle's wading ability.

[0037] The second air intake 112 is located at the right headlight. The second air intake 112 is higher than the first air intake 111. When the vehicle is wading through deep water and the radiator crossbeam is submerged, fresh air is drawn into the second air intake 112 through the gap between the headlight and the engine hood 10. In this embodiment, the gap width is 5mm. The air then enters the cavity 101 from the second air intake 112, and then from the air outlet 12 into the air filter 20 and finally into the engine. The fresh air entering through the second air intake 112 can maintain the air supply required for the vehicle to operate at low speeds while wading through water.

[0038] This application also provides a vehicle including an engine, headlights, and an engine intake structure as described above.

[0039] The cavity 101 of this application is located above the upper crossbeam of the water tank, which raises the air intake height of the vehicle's engine and prevents water from directly entering the engine when the vehicle is wading through water at low elevations. At the same time, the cavity 101 serves as an air intake channel, raising the engine's air intake path to inside the engine hood 10, ensuring stable engine operation when wading through water.
