Description

Technical Field

[0001] This utility model relates to the technical field of automotive front-end air guide systems, and in particular to an upper air guide channel and an upper air guide assembly. Background Technology

[0002] In existing closed-off front fascia designs for automobiles, the upper air intake grille has been eliminated, leaving only the lower air intake grille. However, eliminating the upper air intake grille can lead to a decrease in the ventilation rate of the front cooling module in hybrid vehicles, as well as an increase in engine intake air temperature, drag, and the risk of overheating.

[0003] Therefore, it is necessary to design an upper air guide channel and upper air guide assembly to improve the ventilation rate of the front-end heat dissipation module, the engine intake air temperature, resistance, and crown water risk. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide an upper air guide channel and upper air guide assembly that improves the ventilation rate of the front heat dissipation module, the engine intake air temperature, resistance and crown water risk.

[0005] The present invention provides an upper air guide channel, including a channel body, an upper vent and a lower vent. The upper vent is located at the upper end of the channel body, and the lower vent is located at the lower end of the channel body. The inner wall of the channel body is provided with at least two baffles. The baffles are distributed at different heights on the inner wall of the channel body, and the baffles in adjacent layers are staggered in the horizontal direction.

[0006] Furthermore, the cross-sectional areas of the upper and lower ends of the channel body are greater than the cross-sectional area of ​​the middle part of the channel body.

[0007] Furthermore, a ring of foam is connected to the edge of the upper vent, and a ring of foam is connected to the edge of the lower vent.

[0008] Furthermore, the lower ventilation opening is provided with a pre-installed claw and multiple plug-in pins.

[0009] Furthermore, the baffle includes a lower baffle and an upper baffle, the lower baffle is located near the lower vent, the upper baffle is located near the upper vent, and an S-shaped airflow path is formed inside the channel body.

[0010] Furthermore, it also includes damper blades, which are installed inside the channel body and rotatably connected, and are used to close or open the lower ventilation opening.

[0011] Furthermore, it also includes a motor, which is installed outside the channel body and is connected to the damper blades via a transmission rod.

[0012] Furthermore, the transmission rod is provided with a first limiting member and a second limiting member;

[0013] The first limiting member is used to limit the transmission rod to a first extreme position of clockwise rotation. At the first extreme position, the damper blade opens the lower ventilation port to the maximum.

[0014] The second limiting member is used to limit the second extreme position of the transmission rod to rotate counterclockwise. At the second extreme position, the damper blade closes the lower ventilation port.

[0015] Furthermore, the end of the damper blade is coated with a layer of rubber.

[0039] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0040] It is readily understood that, based on the technical solution of this utility model, various structural and implementation methods can be interchanged by those skilled in the art without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0041] The directional terms such as up, down, left, right, front, back, front, back, top, and bottom mentioned or possibly used in this specification are defined relative to the structures shown in the accompanying drawings. They are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive.

[0042] In some embodiments of this utility model, such as Figure 1-5 As shown, the upper air guide channel 10 includes a channel body 1, an upper vent 2 and a lower vent 3. The upper vent 2 is located at the upper end of the channel body 1, and the lower vent 3 is located at the lower end of the channel body 1. The inner wall of the channel body 1 is provided with at least two baffles 4. The baffles 4 are distributed at different heights on the inner wall of the channel body 1, and the adjacent baffles 4 are staggered in the horizontal direction.

[0043] Specifically, such as Figures 1-2 As shown, the upper air guide channel 10 includes a channel body 1, which is a hollow tubular structure. The upper vent 2 is the opening at the upper end of the channel body 1, and the lower vent 3 is the opening at the lower end of the channel body 1.

[0044] like Figure 3 As shown, the lower vent 3 is used to connect with the upper air guide plate 20, and the upper air guide plate 20 guides the airflow at the lower air intake grille into the upper air guide channel 10.

[0045] The upper vent 2 is used to connect with the external air intake pipe, guide the airflow into the air intake pipe, and then guide the airflow into the cylinder inside the car's engine.

[0046] Furthermore, the ventilation body 1 is arranged longitudinally inside the vehicle. As the airflow passes through the upper air guide plate 20, it also flows through the radiator core at the front end. The radiator core at the front end heats the airflow, thereby generating hot air rising in the ventilation body 1 and forming a negative pressure zone in the longitudinal channel. This prompts cold air to be replenished from the bottom, which is conducive to forming a continuous airflow from bottom to top and accelerates the airflow speed.

[0047] Because the airflow entering from the lower air intake grille is at a lower temperature, even if the radiator core at the front heats the airflow, the temperature rise is relatively small, which helps to reduce the engine intake air temperature.

[0048] like Figure 5 As shown, the inner wall of the channel body 1 is provided with two baffles 4. The baffles 4 are distributed at different heights on the inner wall of the channel body 1, and the adjacent baffles 4 are staggered in the horizontal direction. Figure 5The red arrow in the middle indicates the direction of airflow. The airflow enters the lower vent 3 from the upper guide plate 20, and then flows into the channel body 1 from the lower vent 3. When it passes the first baffle 4, the airflow direction is changed by the first baffle 4, and it moves towards... Figure 5 The airflow flows to the left; then the airflow continues to flow upwards, encountering the second baffle 4, which again changes the direction of the airflow, causing the airflow to move towards... Figure 5 The air flows to the right and eventually exits from the upper vent 2. Because the lower air intake grille is positioned low, it easily draws in moisture from the ground; and after the upper air intake grille is closed, the moisture drawn in is more likely to rise higher within the closed path. When the moisture comes into contact with the baffle 4, the baffle 4 can block the moisture, thereby reducing the amount of moisture entering the engine and lowering the risk of crown water buildup.

[0049] Furthermore, the cross-sectional areas of the upper and lower ends of the channel body 1 are larger than the cross-sectional area of ​​the middle part of the channel body 1. This can accelerate the airflow velocity through the channel body 1, further improving intake efficiency, and enhancing engine thermal efficiency and power output.

[0050] Furthermore, such as Figure 2 As shown, a ring of foam 5 is connected to the edge of the upper vent 2, and a ring of foam 5 is connected to the edge of the lower vent 3.

[0051] like Figures 3-4 As shown, the upper air guide channel 10 is installed above the upper air guide plate 20. The foam 5 at the edge of the lower vent 3 is pressed into the gap between the upper air guide channel 10 and the upper air guide plate 20, which plays a sealing role. The airflow can only enter the upper air guide channel 10 through the ventilation hole 201 on the upper air guide plate 20.

[0052] Furthermore, such as Figure 2 As shown, a pre-installed claw 6 and multiple plug-in pins 7 are provided at the lower ventilation opening 3.

[0053] The pre-installed clips 6 are used to pre-lock into the upper air guide plate 20 for pre-installation. Multiple plug-in posts 7 are spaced around the lower air vent 3. After the plug-in posts 7 are inserted into the upper air guide plate 20, they are welded to the hot plate of the upper air guide plate 20 to complete the fixed connection.

[0054] Furthermore, such as Figure 5 As shown, the baffle 4 includes a lower baffle 41 and an upper baffle 42. The lower baffle 41 is located near the lower vent 3, and the upper baffle 42 is located near the upper vent 2. An S-shaped airflow path is formed inside the channel body 1.

[0055] The lower baffle 41 is located above the lower vent 3. The lower baffle 41 can block some of the water vapor in the airflow. After the airflow passes through the upper baffle 42, the upper baffle 42 further blocks some of the water vapor.

[0056] Preferably, more baffles 4 can be installed inside the channel body 1. Multiple baffles 4 are distributed at different heights and staggered along the horizontal direction.

[0057] Furthermore, such as Figures 5-6 As shown, it also includes a damper blade 8, which is installed inside the channel body 1 and is rotatably connected. The damper blade 8 is used to close or open the lower ventilation port 3.

[0058] Specifically, such as Figure 6 As shown, the damper blade 8 is long and narrow, arranged horizontally inside the channel body 1. The two ends of the damper blade 8 pass through the wall of the channel body 1 and are rotatable relative to each other.

[0059] like Figure 10 As described above, when the damper blade 8 rotates downward, it closes the lower ventilation port 3, preventing airflow from entering the channel body 1.

[0060] like Figure 11 As shown, when the damper blade 8 rotates upward, the lower vent 3 is opened, allowing airflow to enter the channel body 1.

[0061] In hybrid vehicles, when the engine is not running, the damper blades 8 can be controlled to close the lower vent 3, preventing gas from entering the channel body 1. Since the engine is not operating at this time, no engine intake is required. The airflow can then flow directly to the front-end cooling module, improving ventilation and heat dissipation.

[0062] When the engine is running, the control damper blades 8 open the lower ventilation port 3, and the gas enters the channel body 1 and then flows into the engine air intake to supplement the engine air intake.

[0063] In addition, when the water level under the vehicle is detected to exceed the set height, in order to avoid damage to the engine by moisture, the lower air vent 3 can be closed or partially closed by controlling the damper blades 8 to prevent moisture from entering the engine.

[0064] Furthermore, such as Figure 6 As shown, it also includes a motor 9, which is installed outside the channel body 1 and is connected to the damper blade 8 via a transmission rod 81.

[0065] like Figure 9 As shown, the motor 9 is fixedly connected to the outer wall of the channel body 1 by two screws 91. The motor 9 drives the damper blade 8 to rotate via the transmission rod 81.

[0066] like Figure 7 As shown, when the motor 9 rotates in the forward direction, it drives the damper blades 8 to rotate clockwise and opens the lower ventilation port 3.

[0067] like Figure 8 As shown, when the motor 9 rotates in the reverse direction, it drives the damper blades 8 to rotate counterclockwise and closes the lower ventilation port 3.

[0068] Furthermore, such as Figures 7-8 As shown, the transmission rod 81 is provided with a first limiting member 811 and a second limiting member 812;

[0069] The first limiting member 811 is used to limit the first extreme position of the clockwise rotation of the transmission rod 81. At the first extreme position, the damper blade 8 opens the lower ventilation port 3 to the maximum.

[0070] The second limiting member 812 is used to limit the second extreme position of the transmission rod 81 to rotate counterclockwise. At the second extreme position, the damper blade 8 closes the lower ventilation port 3.

[0071] Specifically, such as Figure 7 As shown, the transmission rod 81 is connected to the motor 9 at one end, and a turntable is provided on the turntable. A notch is opened on the turntable, and a first limiting member 811 is provided at one end of the notch. The corresponding motor 9 housing is provided with a first stop 92. When the first limiting member 811 rotates clockwise to contact the first stop 92, the damper blade 8 is at the first limit position, and at this time the lower ventilation port 3 is opened to the maximum.

[0072] like Figure 8 As shown, a second limiting member 812 is provided at the other end of the notch, and a second stop 93 is provided on the housing of the corresponding motor 9. When the second limiting member 812 rotates counterclockwise to contact the second stop 93, the damper blade 8 is in the second limit position, at which time the lower ventilation port 3 is completely closed.

[0073] Furthermore, such as Figures 7-8 As shown, the end of the damper blade 8 is provided with a layer of adhesive 82. The damper blade 8 has a long, strip-shaped structure, and the adhesive 82 is wrapped around the long side of the damper blade 8. Figure 10 As shown, when the damper blade 8 rotates downward to close the lower ventilation port 3, the rubber coating 82 seals the edge of the lower ventilation port 3 to prevent airflow leakage.

[0074] In this embodiment, the upper air guide duct 10 can guide the lower-temperature airflow from the lower air intake grille to the engine air intake, supplementing the engine's intake air volume and effectively reducing the engine's intake air temperature. Simultaneously, it can also reduce intake resistance. Furthermore, the baffle 4 prevents moisture from entering the engine, avoiding the risk of crown water. The upper air guide duct 10 can also accelerate the airflow speed, improving intake efficiency. In addition, depending on different operating conditions, the damper blades 8 can control the opening and closing of the lower vent 3.

[0075] In other embodiments of this utility model, such as Figure 3As shown in Figure 4, the upper air guide assembly includes an upper air guide plate 20 and an upper air guide channel 10 as described in any of the above embodiments. The upper air guide plate 20 has ventilation holes 201, the upper air guide channel 10 is installed on the upper air guide plate 20, and the lower ventilation port 3 is connected to the ventilation holes 201.

[0076] The lower air intake grille (not shown) is installed below the upper air guide plate 20, and the upper air guide duct 10 is connected to the engine (not shown) through other external components above, so as to realize the flow path of airflow from the lower air intake grille to the upper air guide plate 20, the upper air guide duct 10 and the engine.

[0077] The above description is merely the principle and preferred embodiment of this utility model. It should be noted that, for those skilled in the art, several other modifications can be made based on the principle of this utility model, and these modifications should also be considered within the protection scope of this utility model.
