Abstract
Description
Technical Field
[0001] The present disclosure relates to the field of vehicle technology, and in particular to an engine air intake structure and a vehicle. Background Art
[0002] The air intake structure of a car is an important component of the normal operation of the engine. Its main function is to provide the engine with sufficient air to mix with the fuel and burn to generate power. The goal of the car's air intake structure design is to provide the maximum air intake volume while reducing the air intake pressure loss to improve the engine's performance and fuel efficiency. However, when a car is wading, especially when meeting other cars in deep water, it is easy to cause waves on the water surface. When the car is moving forward and encounters waves, the engine's air intake system is extremely susceptible to the impact of the waves, causing water to enter. Although the engine air intake system in the existing technology is designed with a certain wading capability, it is basically limited to calm water surfaces. In reality, the water surface is not calm, and often produces large water waves with large impact kinetic energy. The existing engine air intake structure design has limited ability to prevent water from entering due to the impact of water waves. The air intake structure is easily flooded, causing damage to the engine or even scrapping. Utility Model Content
[0003] The present disclosure aims to at least solve the technical problems in the prior art that the engine air intake structure design has limited ability to prevent water from entering due to wave impact, and the air intake structure is easily infiltrated with water, resulting in damage or scrapping of the engine.

[0005] In some embodiments, the direction of the second air inlet is the same as the direction of the air outlet.
[0006] In some embodiments, the second air intake is toward the rear of the vehicle.
[0007] In some embodiments, a chamber is provided on the second air inlet section, and the chamber is arranged opposite to the second air inlet.

[0009] In some embodiments, a partition is provided in the chamber, and the partition is provided parallel to the bottom of the chamber, and the bottom of the chamber is lower than the bottom of the air inlet portion.
[0010] In some embodiments, the main body is a U-shaped or arc-shaped structure, and the air inlet is arranged parallel to the first air inlet section.
[0011] In some embodiments, a reinforcement member is provided between an outer wall of the chamber and an outer wall of the second air inlet section.

[0030] Specific embodiments of the present disclosure will be described hereinafter with reference to the accompanying drawings; however, it should be understood that the claimed embodiments are merely examples of the present disclosure, which may be implemented in a variety of ways. Well-known and / or repetitive functions and structures are not described in detail to avoid obscuring the present disclosure with unnecessary or redundant detail. Therefore, the specific structural and functional details claimed herein are not intended to be limiting, but rather serve merely as a basis and representative basis for teaching those skilled in the art to variously employ the present disclosure with substantially any suitable detailed structure.
[0031] In this embodiment, the length direction of the vehicle refers to the x-direction of the vehicle, and the height direction of the vehicle refers to the z-direction of the vehicle.
[0032] The first embodiment of the present disclosure provides an engine intake structure, such as Figure 1-Figure 4 As shown, the engine intake structure is connected to the vehicle's air filter 200 through an intake pipe 100. When the vehicle is running, air enters the air filter 200 from the intake structure and then enters the engine.
[0033] The engine intake structure includes a first intake section 1 having a first intake port 11 and an outlet port 12. When the vehicle is running normally, gas enters the first intake section 1 through the first intake port 11 and enters the intake pipe 100 through the outlet port 12.
[0034] The first air intake section 1 can be configured as a straight structure and arranged along the length of the vehicle, wherein the first air inlet 11 is arranged toward the front of the vehicle and the air outlet 12 is arranged toward the rear of the vehicle. The air intake achieved by the first air intake section 1 has the characteristics of smooth air intake and low flow resistance.
[0035] In another embodiment, the first air intake section 1 can be configured as a curved structure, comprising a first segment 13 and a second segment 14. The air outlet 12 is disposed at the end of the second segment 14, and the first air intake 11 is disposed at the end of the first segment 13, with the air outlet 12 facing the rear of the vehicle. The first air intake 11 is tilted downward along the height of the vehicle to prevent rainwater from entering the first air intake section 1 through the first air intake 11 during rainfall. This configuration of the first air intake section 1 ensures high air intake volume and low air intake resistance, ensuring optimal engine performance and fuel economy under normal driving conditions.
[0036] A second air intake section 2 is provided on the first air intake section 1. The first air intake section 1 and the second air intake section 2 are connected. The second air intake section 2 has a second air intake port 21. The angle between the air intake direction of the first air intake port 11 and the air intake direction of the second air intake port 21 is 90° to 180°. Specifically, when the vehicle is wading, the gas enters the second air intake section 2 through the second air intake port 21 and then enters the air intake pipe 100 through the second segment 14. Here, the air intake direction of the first air intake port 11 is different from the air intake direction of the second air intake port 21. When the vehicle is driving normally, air is taken in through the first air intake port 11; when the vehicle is wading, air is taken in through the second air intake port 21. The air intake direction is opposite to the direction of the water wave impact, thereby preventing water from flowing into the engine when wading.
[0037] The second air inlet 21 here is set higher than the first air inlet 11. Compared with normal driving, the height of the air intake position is increased when wading, and water is not easy to reach the height position of the second air inlet 21, reducing the possibility of water entering the air filter 200 through the second air inlet 21.
[0038] In this embodiment, the direction of the second air inlet 21 is the same as that of the air outlet 12 , which is beneficial for improving the smoothness of the gas entering the air inlet pipe 100 from the air outlet 12 .
[0039] In another embodiment, the second air inlet 21 faces the rear of the vehicle. When the second air inlet 21 takes in air, the air intake direction is the same as the vehicle's travel direction and opposite to the direction of water flow entering the air intake structure, thereby preventing water waves from directly rushing into the air intake structure.
[0040] like Figure 2 As shown, the second air intake section 2 includes a main body 22 and an air intake portion 23. The second air intake 21 is provided at the end of the air intake portion 23, and the end of the main body 22 is connected to the first air intake section 1. A chamber 24 is provided on the second air intake section 2. Specifically, the chamber 24 is provided at the connection position between the main body 22 and the air intake portion 23, and the chamber 24 is arranged opposite to the second air intake 21. If the water depth is too deep or the kinetic energy of the water is too large and flows into the air intake portion 23 from the second air intake 21, the water will be guided into the chamber 24 along the air intake portion 23, reducing the possibility of water entering the main body 22, effectively avoiding the erosion of the interior of the engine by water, and protecting the long-term stable operation of the engine.
[0041] The bottom of the chamber 24 is lower than the bottom of the air inlet portion 23 , which helps the water flowing in from the second air inlet 21 to fall into the chamber 24 under the action of gravity, and thus gather inside the chamber 24 .
[0042] In this embodiment, a partition 25 is provided in the chamber 24 to divide the chamber 24 into multiple areas. The partition 25 is provided parallel to the bottom of the chamber 24. The water flow flowing into the chamber 24 will be cut by the partition 25, thereby reducing the impact kinetic energy of the water flow, and further reducing the possibility of the water flow entering the main body 22.
[0043] In other embodiments, the partition 25 and the bottom of the chamber 24 are arranged to be inclined. For example, the inclination angle of the partition 25 is -35° to 30°. The water flowing into the chamber 24 will be cut by the partition 25, thereby reducing the impact kinetic energy of the water flow. It can adapt to various wading driving environments from shallow water to deep water, and ensure that when the vehicle is driving in wading, no matter how the water level changes, it can effectively prevent water from entering the engine, thereby improving driving safety and vehicle adaptability.
[0044] A drainage hole 26 is provided at the bottom of the chamber 24 to drain the water in the chamber 24. At least one drainage hole 26 is provided. Providing multiple drainage holes 26 can increase the speed of water drainage, thereby preventing potential damage to the engine caused by residual water, allowing the engine to quickly resume normal operation and ensuring driving safety.
[0045] In this embodiment, the air inlet portion 23 is arranged parallel to the first air inlet section 1, and the main body 22 has a U-shaped or arc-shaped structure, forming a height difference between the air inlet portion 23 and the first air inlet section 1. In extreme cases, a small amount of water entering the main body 22 will return to the air inlet portion 23 under the action of gravity and will not enter the first air inlet section 1 along the main body 22. By providing this height difference, the inertia of water and the effects of gravity are utilized to reduce the possibility of water directly entering the air inlet pipe 100.
[0046] At the same time, the main body 22 is a U-shaped or arc-shaped structure, which can optimize the spatial layout. In a limited space, the length of the second air intake section 2 can be increased. When the gas containing moisture passes through the U-shaped or arc-shaped second air intake section 2, the air can pass through smoothly, increasing the difficulty of water flow, thereby reducing the possibility of water flow entering the air filter 200.
[0047] In order to enhance the overall strength of the chamber 24 and the second air intake section 2 , a reinforcement 27 is provided between the outer wall of the chamber 24 and the outer wall of the second air intake section 2 , and a reinforcement 27 is provided between the outer wall of the first air intake section 1 and the outer wall of the second air intake section 2 .
[0048] In this embodiment, the shapes of the pipe openings of the first air inlet section 1 and the second air inlet section 2 can be set to be square, circular or irregular.
[0049] like Figure 3 and Figure 4As shown, an adjustment assembly 3 is provided at the connection between the first air intake section 1 and the second air intake section 2. The adjustment assembly 3 is used to block the first air intake section 1 or the second air intake section 2. Specifically, during normal driving, the adjustment assembly 3 blocks the second air intake section 2, allowing air to enter through the first air intake port 11. During wading, the adjustment assembly 3 blocks the first air intake section 1, allowing air to enter through the second air intake port 21. Changing the operating state of the air intake structure through the adjustment assembly 3 is quick and convenient.
[0050] Specifically, the regulating assembly 3 includes a driving portion 31 and a blocking portion 32. The driving portion 31 is connected to the blocking portion 32, and the blocking portion 32 is rotatably connected to the connection position between the first air inlet section 1 and the second air inlet section 2. The driving member controls the regulating member 322 to switch between two working states. In the first working state, the blocking portion 32 is connected to the inner wall of the first air inlet section 1. At this time, the first segment 13 and the second segment 14 of the first air inlet section 1 are connected, and the first air inlet section 1 and the second air inlet section 2 are cut off. In the second working state, the blocking portion 32 is connected to the inner wall of the second air inlet section 2. At this time, the first segment 13 and the second air inlet section 2 are connected, and the first segment 13 and the second segment 14 are cut off.
[0051] The drive unit 31 can be configured as either a manual or automatic drive. If configured as an automatic drive, the automatic drive is connected to a water level sensor that detects the water level when the vehicle is wading. Once the water level reaches a preset threshold, the sensor sends a signal to the automatic drive, automatically switching the sealing portion 32 to the second operating position. If configured as a manual drive, the drive member 41 can be configured as an adjustment handle.
[0052] The blocking portion 32 can be configured as a shaft connected to an adjustable baffle 25, which is movably connected to the intake structure, and the adjustable baffle 25 is connected to the shaft. The adjustable baffle 25 is preferably circular, which allows for more uniform airflow distribution, reduces airflow resistance, and improves intake efficiency. Alternatively, the adjustable baffle 25 can be configured in other or irregular shapes.
