Description

Technical Field

[0001] This utility model relates to the technical field of automotive air intake devices, and in particular to an automotive air intake device. Background Technology

[0002] Automotive air intake systems are typically installed in the engine compartment, and their core function is to create a flow channel for outside air to enter the passenger compartment's air conditioning system. In rainy weather, the air flowing into the car's air intake system mixes with some rainwater. However, in existing automotive air intake systems, the high-speed airflow mixed with rainwater passes through the air intake system and directly enters the car's air conditioning system. This can easily cause damage to the electrical components in the air conditioning system, affecting its lifespan; and may even lead to water leaks inside the vehicle.

[0003] Therefore, there is an urgent need to design an automotive air intake device to solve the above technical problems. Utility Model Content

[0004] The purpose of this invention is to provide an automotive air intake device that can separate water droplets mixed in high-speed airflow, protect electrical components inside the vehicle, reduce or avoid the risk of water leakage inside the vehicle, and extend its service life.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] This utility model provides an automotive air intake device, comprising:

[0007] The housing has an internal channel, an air inlet, and an air outlet, both of which are connected to the internal channel;

[0008] The inner wall of the housing has a first bend and a second bend, the first bend being located near the air inlet and the second bend being located near the air outlet; a portion of the sidewall of the housing is respectively enclosed to form a first water collection trough and a second water collection trough, the first water collection trough being located below the first bend and the second water collection trough being located below the second bend.

[0009] The housing also includes a baffle, which is disposed between the first water collection tank and the second water collection tank and isolates the first water collection tank and the second water collection tank;

[0010] The first bend can force the airflow entering from the air inlet to change its flow direction, so as to separate the water droplets mixed in the airflow into the first water collection tank by centrifugal force; the second bend can force the airflow entering from the first bend to change its flow direction, so as to separate the water droplets mixed in the airflow into the second water collection tank by centrifugal force.

[0011] As an optional technical solution for an automotive air intake device, the automotive air intake device further includes a guide plate, which is disposed in the internal channel, with one end of the guide plate connected to the inner wall of the housing and the other end inclined toward the first water collection tank.

[0012] As an optional technical solution for an automotive air intake device, there is a gap between the top of the baffle and the guide plate, and the gap connects the internal channel at the first bend and the internal channel at the second bend.

[0013] As an optional technical solution for an automotive air intake device, the automotive air intake device further includes an air damper, which is rotatably mounted on the housing and configured to open and close the air inlet.

[0014] As an optional technical solution for automotive air intake devices, the edge of the air damper is provided with an elastic seal.

[0020] The beneficial effects of this utility model include at least the following:

[0021] This utility model provides an automotive air intake device, which includes a housing, an internal channel, an air inlet, an air outlet, a first bend, a second bend, a first water collection trough, a second water collection trough, and a baffle. The housing has an internal channel, an air inlet, and an air outlet, both of which communicate with the internal channel. The inner wall of the housing has a first bend and a second bend, with the first bend located near the air inlet and the second bend near the air outlet. A portion of the housing's sidewalls respectively forms a first water collection trough and a second water collection trough, with the first water collection trough located below the first bend and the second water collection trough located below the second bend. A baffle is disposed between the first and second water collection troughs and isolates them. The first bend forces the airflow entering from the air inlet to change its flow direction, thereby separating water droplets mixed in the airflow into the first water collection trough through centrifugal force. The second bend forces the airflow entering from the first bend to change its flow direction, thereby separating water droplets mixed in the airflow into the second water collection trough through centrifugal force.

[0022] The inner wall of the housing has a first bend and a second bend. After entering through the air inlet, the airflow is forced to change direction at the first bend. Because water droplets are more massive than air, they are thrown against the inner wall of the first bend by centrifugal force, detaching from the airflow and flowing into the first water collection tank below. The remaining unseparated water droplets enter the second bend with the airflow, where they are again separated into the second water collection tank by centrifugal force generated by the bend. This two-stage separation of water droplets in the airflow significantly improves rainwater separation efficiency, preventing rainwater from entering the vehicle's electrical components, protecting them, and extending their lifespan; it also avoids or reduces the risk of water leakage inside the vehicle.

[0036] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0037] This embodiment provides an automotive air intake device that can separate water droplets mixed in high-speed airflow, protect electrical components inside the vehicle, reduce or avoid the risk of water leakage inside the vehicle, and extend service life.

[0038] like Figures 1-3As shown, the automotive air intake device mainly includes a housing 10, an internal channel, an air inlet 11, an air outlet 12, a first bend 13, a second bend 14, a first water collection trough 15, a second water collection trough 16, and a baffle 19. The housing 10 has an internal channel, an air inlet 11, and an air outlet 12, both of which communicate with the internal channel. The inner wall of the housing 10 has a first bend 13 and a second bend 14, with the first bend 13 located near the air inlet 11 and the second bend 14 located near the air outlet 12. A portion of the sidewalls of the housing 10 are respectively arranged to form a first water collection trough 15 and a second water collection trough 16, with the first water collection trough 15 located below the first bend 13 and the second water collection trough 16 located below the second bend 14. The baffle 19 is disposed between the first water collection trough 15 and the second water collection trough 16 and isolates them. The first bend 13 can force the airflow entering from the air inlet 11 to change its flow direction, so as to separate the water droplets mixed in the airflow into the first water collection tank 15 by centrifugal force; the second bend 14 can force the airflow entering from the first bend 13 to change its flow direction, so as to separate the water droplets mixed in the airflow into the second water collection tank 16 by centrifugal force.

[0039] Based on the above design, in this embodiment, the inner wall of the housing 10 has a first bend 13 and a second bend 14. After the airflow enters from the air inlet 11, it is forced to turn at the first bend 13. Since the mass of the water droplets is greater than that of the air, the water droplets are thrown towards the inner wall of the first bend 13 under the action of centrifugal force. After detaching from the airflow, they flow into the first water collection tank 15 below. The remaining unseparated water droplets enter the second bend 14 with the airflow and are separated into the second water collection tank 16 again due to the centrifugal force generated by the turning. By separating the water droplets in the airflow twice, the rainwater separation efficiency is significantly improved, preventing rainwater from entering the electrical components in the car, protecting the electrical components, and extending their service life; at the same time, it avoids or reduces the risk of water leakage inside the car.

[0040] It should be noted that, Figure 3 The solid arrows in the diagram indicate the direction of airflow, while the dashed arrows indicate the direction of water droplets.

[0041] In addition, by setting the baffle 19, the baffle 19 isolates the first water collection tank 15 and the second water collection tank 16, preventing the rainwater collected by the first water collection tank 15 from being drawn into the second turning part 14 by the airflow, ensuring that the two-stage separation does not interfere with each other, further reducing the probability of rainwater entering the air outlet 12 with the airflow, and improving the rainwater separation efficiency.

[0042] In some alternative embodiments, the first bend 13 bends 90° to the right and the second bend 14 bends 90° to the left, so that the internal channel forms an "S" shaped path; the inner walls of the first bend 13 and the second bend 14 are both rounded, which reduces airflow resistance while enhancing the centrifugal effect on raindrops.

[0043] In some optional embodiments, the first water collection tank 15 and the second water collection tank 16 are both arc-shaped grooves extending along the inner walls of the corresponding first bend 13 and second bend 14, with the groove depth gradually increasing from the inlet to the end, so that water droplets can converge at the end.

[0044] Optionally, in this embodiment, the baffle 19 is a straight plate structure integrally formed with the housing 10.

[0045] like Figure 3 As shown, in this embodiment, the car air intake device also includes a guide plate 20, which is disposed in the internal channel, and one end of the guide plate 20 is connected to the inner wall of the housing 10, while the other end is inclined toward the first water collection tank 15.

[0046] The tilt angle of the guide plate 20 allows water droplets to quickly detach from the inner wall and enter the first water collection tank 15 under the guidance of gravity and the guide plate 20, reducing the residence time of water droplets on the inner wall of the housing 10 and preventing them from being carried away by the airflow again. In addition, the guide plate 20 can also streamline the airflow, allowing the airflow to pass more smoothly through the first bend 13, reducing the problem of decreased water droplet separation efficiency caused by airflow turbulence.

[0047] For example, both the deflector 20 and the housing 10 are made of engineering plastics, and the included angle between the horizontal inner wall of the deflector 20 and the housing 10 is set to 45°-60°.

[0048] like Figure 3 As shown, in this embodiment, there is a gap between the top of the baffle 19 and the guide plate 20, which connects the internal channels at the first bend 13 and the second bend 14. This gap serves as an airflow channel. Located at the top of the baffle 19, water droplets mainly accumulate in the first and second water collection tanks 15 and 16 below due to gravity. Therefore, the gap only allows airflow to pass through and does not affect the isolation effect of the first and second water collection tanks 15 and 16, preventing rainwater collected in the first water collection tank 15 from being drawn into the second bend 14 by the airflow.

[0049] like Figures 1-3 As shown, the car air intake device also includes a damper 30, which is rotatably mounted on the housing 10 and is configured to open and close the air intake 11.

[0050] When the vehicle switches to recirculation mode or when external air intake is not required, the damper 30 closes the air intake 11, blocking external airflow and preventing rainwater, dust, and other impurities from entering the internal passage and air conditioning system. The damper 30 is rotatably mounted on the housing 10 and its opening is adjustable (when not fully closed). By changing the flow area of ​​the air intake 11, the air intake volume is controlled, preventing excessive airflow from entering at high speeds, which could lead to increased air conditioning noise or abnormal airflow, thus improving the comfort of passengers inside the vehicle.

[0051] In some optional embodiments, the damper 30 is a rectangular plate adapted to the shape of the air inlet 11, and is made of a lightweight, high-strength material (such as ABS plastic). A metal rotating shaft is provided on one edge of the damper 30, and both ends of the rotating shaft are connected to the housing 10 via bearings; the rotating shaft extends beyond the outer side of the housing 10 for easy connection to a drive component (e.g., actuator 40). The damper 30 can rotate 0°-90° around the rotating shaft; it is fully open at 0° (parallel to the plane of the air inlet 11) and fully closed at 90° (perpendicular to the plane of the air inlet 11), with intermediate angles corresponding to different opening degrees of the damper 30.

[0052] Furthermore, the edge of the damper 30 is provided with an elastic seal (not shown in the figure). When the damper 30 is fully closed, the elastic seal can fit tightly against the inner wall of the housing 10 to block the connection between the air inlet 11 and the internal channel.

[0053] The resilient seal has the ability to deform and fill the assembly gap between the damper 30 and the housing 10, improving the sealing performance and preventing external airflow from entering the internal channel of the housing 10. The resilient seal can also buffer the impact force when the damper 30 is closed, reducing collision noise and component wear, and extending service life.

[0054] Alternatively, the resilient seal can be made of aging-resistant EPDM rubber.

[0055] like Figure 1 As shown, the car air intake device in this embodiment also includes an actuator 40, which is disposed on the outer wall of the housing 10. The actuator 40 is driven to be connected to the rotation shaft of the damper 30 to adjust the opening of the damper 30.

[0056] Specifically, actuator 40 can receive external signals (such as commands from the vehicle's ECU) and automatically drive damper 30 to rotate to the target opening, achieving automatic adjustment. For example, when driving at high speed, the ECU controls actuator 40 to reduce the opening of damper 30 to prevent excessive air intake; in rainy weather, the opening is reduced to decrease the amount of rainwater brought in.

[0057] For example, the actuator 40 can be a DC geared motor, the output shaft of which is connected to the rotation shaft of the damper 30 via a linkage mechanism. For instance, the motor shaft drives the crank of the linkage mechanism to rotate, and the crank pushes the swing arm on the shaft of the damper 30 through the connecting rod, thereby causing the damper 30 to rotate.

[0058] In some optional embodiments, the vehicle air intake device also includes a liquid level sensor (not shown in the figure) disposed in the first water collection tank 15 and the second water collection tank 16. The liquid level sensor is signal-connected to the actuator 40. When the water accumulation in the first water collection tank 15 or the second water collection tank 16 reaches a preset liquid level, the actuator 40 can drive the damper 30 to reduce the opening to reduce the air intake volume.

[0059] When the water level in the first collection tank 15 or the second collection tank 16 reaches the preset level, the level sensor sends a signal to the actuator 40. The actuator 40 then drives the damper 30 to reduce its opening, thereby reducing the air intake. The reduced air intake correspondingly reduces the amount of rainwater brought in, while also allowing time for drainage from the first collection tank 15 or the second collection tank 16, preventing water overflow and further ensuring the reliability of rainwater separation.

[0060] For example, the liquid level sensor is a float-type liquid level sensor and is fixed on the inner sidewall of the first water collection tank 15 and the second water collection tank 16. The liquid level sensor is connected to the control module of the actuator 40 through a wire.

[0061] like Figures 2-3 As shown, in this embodiment, a first drain outlet 17 is provided at the bottom of the first water collection tank 15, and a second drain outlet 18 is provided at the bottom of the second water collection tank 16. The first drain outlet 17 and the second drain outlet 18 are located at the lowest points of the first water collection tank 15 and the second water collection tank 16, respectively. Gravity allows the accumulated water to drain naturally out of the shell 10, ensuring that the first water collection tank 15 and the second water collection tank 16 always maintain a certain empty capacity and continuously receive separated water droplets.

[0062] Optionally, the first drain outlet 17 and the second drain outlet 18 directly drain water into the drainage area of ​​the engine compartment.

[0063] Furthermore, in this embodiment, both the first drain outlet 17 and the second drain outlet 18 are equipped with one-way valves (not shown in the figure). The one-way valves only allow the water accumulated in the first water collection tank 15 and the second water collection tank 16 to be discharged to the outside of the housing 10. External water flow cannot enter the first water collection tank 15 through the first drain outlet 17 or the second water collection tank 16 through the second drain outlet 18, effectively preventing backflow. The one-way flow characteristic of the one-way valves does not affect the normal drainage of the first water collection tank 15 and the second water collection tank 16, while preventing external impurities (such as silt) from entering the first water collection tank 15 and the second water collection tank 16 through the first drain outlet 17 and the second drain outlet 18 and blocking the internal channels.

[0064] For example, the check valve is connected to the first drain port 17 and the second drain port 18 by threads or snaps, which facilitates disassembly and maintenance later.

[0065] The airflow may contain impurities (such as leaves and dust particles). If these impurities enter the internal channels, they may clog the first drain outlet 17 and the second drain outlet 18, affecting rainwater separation and drainage functions. Therefore, in some optional embodiments, a filter screen is provided at the air inlet 11. The filter screen is detachably connected to the housing 10. The mesh size of the filter screen is smaller than the mesh size of the first drain outlet 17 and the second drain outlet 18. This allows impurities larger than the mesh size of the filter screen (such as leaves and large dust particles) to be intercepted, preventing them from entering the internal channels and clogging the first drain outlet 17 and the second drain outlet 18. The filter screen is detachable, facilitating regular cleaning or replacement and preventing the filter screen itself from clogging and affecting the airflow.

[0066] For example, the filter screen is made of nylon mesh or stainless steel mesh.

[0067] For example, the edge of the air inlet 11 of the housing 10 is provided with an annular groove, and the edge of the filter screen is provided with an elastic clip that matches the annular groove, so that the filter screen can be detachably connected by elastic snap-fit.

[0068] For example, the filter screen and the air inlet 11 have the same shape, such as being rectangular, and the edges are provided with reinforced borders to enhance the structural strength of the filter screen and prevent deformation.

[0069] Obviously, the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the protection scope of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments.
