[0034] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0035] Reference below Figure 1-Figure 3 The vent of a vehicle according to an embodiment of the utility model is described. The vent is a one-way valve arranged on the rear part of the side wall or the rear tail plate assembly of the vehicle, which is used to balance the air pressure inside and outside the vehicle and maintain the air circulation inside the vehicle.

[0036] like Figure 1 and Figure 3 As shown, the air vent of a vehicle according to an embodiment of the utility model includes: a vent body 1, the vent body 1 is formed with an assembly hole 11; an elastic member 2, the elastic member 2 is annular to define an air outlet channel 21, the elastic member 2 is assembled in the assembly hole 11 and is fixedly connected to the vent body 1, the inlet of the air outlet channel 21 is suitable for communicating with the interior of the vehicle, and the end of the elastic member 2 away from the vent body 1 is formed with a closing section 3, when the pressure in the air outlet channel 21 reaches a preset value, the closing section 3 opens to open the outlet 211 of the air outlet channel 21, and when the pressure in the air outlet channel 21 is less than the preset value, the closing section 3 closes to close the outlet 211.

[0037] The vent includes a vent body 1 and an elastic member 2, and the vent body 1 is formed with an assembly hole 11, and the assembly hole 11 can be used to assemble the elastic member 2. The elastic member 2 is annular to define an air outlet channel 21, and the gas can be discharged through the air outlet channel 21. One end of the elastic member 2 is assembled in the assembly hole 11 and is fixedly connected to the vent body 1. For example, the elastic member 2 and the vent body 1 can be bonded and sealed, and the elastic member 2 and the vent body 1 can also be clamped and sealed, but the present application is not limited thereto. The elastic member 2 and the vent body 1 can also be connected in other ways, as long as the elastic member 2 is assembled in the assembly hole 11 and is fixedly sealed to the vent body 1.

[0038] The inlet of the air outlet channel 21 is suitable for communicating with the interior of the vehicle, and the gas inside the vehicle can enter the air outlet channel 21 through the inlet of the air outlet channel 21. The end of the elastic member 2 away from the vent body 1 can be formed with a closing section 3, and the closing section 3 can be automatically opened or closed according to the pressure inside the vehicle. When the pressure inside the air outlet channel 21 reaches a preset value, that is, when the pressure inside the air outlet channel 21 is greater than the pressure outside the vehicle, under the action of the pressure inside the air outlet channel 21, the closing section 3 is opened to open the outlet 211 of the air outlet channel 21, and the gas inside the vehicle can be discharged through the outlet 211 of the air outlet channel 21, thereby achieving the effect of balancing the pressure inside and outside the vehicle. When the pressure inside the air outlet channel 21 is less than the preset value, that is, when the pressure inside the air outlet channel 21 is equal to or less than the pressure outside the vehicle, under the action of the preload force of the closing section 3 itself, the closing section 3 is closed to close the outlet 211, thereby reducing the risk of external water vapor and dust entering the vehicle from the air outlet channel 21, which is conducive to protecting the vehicle environment, thereby improving the comfort of the passengers inside the vehicle.

[0039] Specifically, the elastic member 2 is annular to define the air outlet channel 21, the elastic member 2 is assembled in the assembly hole 11 of the vent body 1, and the elastic member 2 is fixedly connected to the vent body 1, so that the inlet of the air outlet channel 21 is connected to the inside of the vehicle, and the end of the elastic member 2 away from the vent body 1 is formed with a closed section 3, and the closed section 3 automatically opens or closes according to the pressure inside the vehicle. When the vehicle door is closed, the door drives the surrounding air flow into the vehicle, or when the vehicle turns on the external circulation, the external air flow enters the vehicle through the air conditioner, the air pressure inside the vehicle is greater than the air pressure outside the vehicle, and the air flow inside the vehicle flows into the air outlet channel 21 through the inlet of the air outlet channel 21. The air pressure inside the air outlet channel 21 is greater than the air pressure outside the vehicle, and the closed section 3 opens to open the outlet 211 of the air outlet channel 21, and the gas inside the vehicle is discharged outside the vehicle through the outlet 211 of the air outlet channel 21, balancing the air pressure inside and outside the vehicle, and reducing the risk of damaging the eardrum of the occupant due to excessive air pressure inside the vehicle.

[0040] When the rear of the vehicle is wading, the water flow outside the vehicle impacts the closed section 3, and the closed section 3 is more tightly closed under the action of its own elastic preload and the impact force of the water flow, thereby improving the self-sealing property of the closed section 3, blocking water and dust from entering the vehicle, and reducing the risk of water accumulation in the vehicle. When the vehicle encounters a bumpy road while driving, the closed section 3 can also be sealed by its own elastic preload, and will not cause the closed section 3 to open and close cyclically with the bumps of the vehicle, thereby reducing the risk of external airflow and dust entering the vehicle, thereby protecting the vehicle's interior environment and providing a comfortable experience for the passengers in the vehicle.

[0041] Furthermore, the number of the assembly holes 11 of the vent body 1 may be multiple, for example, the number of the assembly holes 11 of the vent body 1 may be 2, 3 or more, and the present application takes 6 assembly holes 11 as an example for illustration. The number of the elastic parts 2 may be multiple, for example, the number of the elastic parts 2 may be 2, 3 or more, and the present application takes 6 elastic parts 2 as an example for illustration. The number of the elastic parts 2 is consistent with the number of the assembly holes 11, that is, one elastic part 2 is assembled in one assembly hole 11, and multiple elastic parts 2 correspond to multiple assembly holes 11 one by one.

[0042] The size of the assembly hole 11 of the vent body 1 and the elastic member 2 can be adjusted according to the installation space of the vehicle. The number of the assembly holes 11 of the vent body 1 and the elastic member 2 can be increased or decreased accordingly according to the size of the vehicle. As long as the total air outlet area of ​​the vent is not less than 10500mm 2 That is, the deformable design enables the vent to be suitable for vehicles of various models and purposes, thereby improving the adaptability of the vent.

[0043] Thus, by providing the elastic member 2, the outlet 211 of the air outlet channel 21 can be opened and closed automatically. When the vehicle door is closed or the external circulation is turned on, the outlet 211 of the air outlet channel 21 is opened by the pressure inside the vehicle, which is conducive to balancing the air pressure inside and outside the vehicle. When the pressure inside the vehicle disappears, the outlet 211 of the air outlet channel 21 is closed by its own preload force, reducing the risk of external water vapor and dust entering the vehicle through the air outlet channel 21, which is conducive to protecting the vehicle environment, thereby improving the comfort of the passengers inside the vehicle.

[0044] In some embodiments of the present invention, Figure 3 As shown, when the closing section 3 is opened, the outlet 211 is opened downward.

[0045] Among them, the elastic member 2 has a main body section 22, which is adjacent to the closing section 3. The main body section 22 has a main body section top wall 221. When the closing section 3 is opened, the main body section top wall 221 can be roughly a straight line, and the outlet 211 can be open downward. The angle between the main body section top wall 221 and the vertical direction can be set to 15° to 30°. For example, the angle between the main body section top wall 221 and the vertical direction can be set to 15°, 25° or 30°, but the present application is not limited to this. The angle between the main body section top wall 221 and the vertical direction can also be set to other angles, as long as the angle between the main body section top wall 221 and the vertical direction is set to between 15° and 30°. Such a setting is conducive to rapid exhaust when the closing section 3 is opened, and when the car door is closed, the air pressure inside and outside the car is quickly balanced, thereby improving the comfort of the passengers in the car.

[0046] Furthermore, there is a temperature difference between the air outlet passage 21 and the outside of the vehicle, which easily generates water vapor in the air outlet passage 21 . The outlet 211 is opened downward to quickly exhaust the air while allowing condensed water vapor and even accumulated water to be quickly discharged, thereby reducing the risk of water vapor flowing back into the vehicle and the risk of abnormal noise caused by accumulated water in the air outlet passage 21 .

[0047] In some embodiments of the present invention, Figure 3 As shown, the axial direction of the outlet 211 forms an angle β with the vertical direction, satisfying the relationship: 35°≤β≤45°.

[0048] Among them, when the closed section 3 is opened, the axial direction of the outlet 211 forms an angle β with the vertical direction, and the angle β formed by the axial direction of the outlet 211 and the vertical direction satisfies the relationship: 35°≤β≤45°. For example, the angle β formed by the axial direction of the outlet 211 and the vertical direction can be set to 35°, 40° or 45°, but the present application is not limited to this. The angle β formed by the axial direction of the outlet 211 and the vertical direction can also be set to other angles, as long as the angle β formed by the axial direction of the outlet 211 and the vertical direction satisfies the relationship: 35°≤β≤45°. Such a setting can make the condensed water vapor and even accumulated water quickly discharged, further reduce the risk of water vapor flowing back into the vehicle, and can also reduce the risk of abnormal noise caused by accumulated water in the air outlet channel 21.

[0049] Furthermore, when the air outlet channel 21 is closed, the overall trend and vertical angle of the air outlet channel 21 can be determined according to the gap between the body sheet metal and the rear bumper. When the air outlet channel 21 is opened, the air outlet channel 21 needs to maintain a gap of at least 15 mm with the surrounding parts. Such a setting is conducive to rapid exhaust while further preventing airflow and water backflow.

[0050] In some embodiments of the present invention, Figure 1As shown, the closed section 3 has a closed section top wall 31 and a closed section bottom wall 32 , and the shape of the closed section top wall 31 matches the shape of the closed section bottom wall 32 .

[0051] The closed section 3 may have a closed section top wall 31 and a closed section bottom wall 32, wherein the closed section top wall 31 is arranged above the closed section bottom wall 32, and the closed section top wall 31 and the closed section bottom wall 32 are in contact under the action of their own elastic preload force to close the closed section 3, and when the air pressure in the air outlet channel 21 is greater than the air pressure outside the vehicle, the closed section top wall 31 and the closed section bottom wall 32 are separated under the action of air pressure to open the closed section 3, so that the closed section 3 can be automatically opened and closed without electric control, thereby improving the working reliability of the vent. The shape of the closed section top wall 31 and the shape of the closed section bottom wall 32 can be adapted, which is conducive to the close contact between the closed section top wall 31 and the closed section bottom wall 32, thereby improving the sealing reliability of the closed section top wall 31 and the closed section bottom wall 32, further reducing the risk of external airflow and dust entering the vehicle, thereby protecting the vehicle interior environment and providing a further comfortable experience for the passengers in the vehicle.

[0052] In some embodiments of the present invention, Figure 2 As shown, the closed section top wall 31 is formed with at least one first arc-shaped segment 311 , and the closed section bottom wall 32 is formed with at least one second arc-shaped segment 321 , and the first arc-shaped segment 311 and the second arc-shaped segment 321 are adapted to each other.

[0053] Among them, the top wall 31 of the closed section is formed with at least one first arc segment 311, for example: the top wall 31 of the closed section can be formed with one first arc segment 311, two first arc segments 311 or more first arc segments 311. The present application takes the top wall 31 of the closed section as an example in which three first arc segments 311 are formed, and the bottom wall 32 of the closed section is formed with at least one second arc segment 321, for example: the bottom wall 32 of the closed section can be formed with one second arc segment 321, two second arc segments 321 or more second arc segments 321. The present application takes the bottom wall 32 of the closed section as an example in which three second arc segments 321 are formed, and the shapes and quantities of the first arc segments 311 and the second arc segments 321 are adapted, which is conducive to the rapid closing of the opening of the closed section 3.

[0054] Furthermore, the first arc segment 311 and the second arc segment 321 can be set to an arc with any radius and any length. In the present application, the first arc segment 311 and the second arc segment 321 are both composed of three arcs with a radius of 3 mm and a length of 6 mm, but the present application is not limited to this. The radius and length of the first arc segment 311 and the second arc segment 321 can be increased or decreased accordingly according to the model of the vehicle, thereby improving the adaptability of the vent to vehicles with different purposes.

[0055] In some embodiments of the present invention, Figure 1 and Figure 3 As shown, the elastic member 2 has a main body section 22, which is connected to the closing section 3. The main body section 22 is assembled in the assembly hole 11 and is fixedly connected to the vent body 1. From the inlet to the outlet 211, the thickness of the main body section 22 gradually decreases, and the thickness of the closing section 3 remains unchanged.

[0056] Among them, the elastic member 2 may have a main body section 22, the main body section 22 is connected to the closing section 3, and the main body section 22 and the closing section 3 may be integrally formed to improve the connection reliability between the main body section 22 and the closing section 3. The main body section 22 is assembled in the assembly hole 11 and fixedly connected to the vent body 1, for example: the main body section 22 and the vent body 1 may be bonded and sealed, or the main body section 22 and the vent body 1 may be clamped and sealed, but the present application is not limited thereto, the main body section 22 and the vent body 1 may also be connected in other ways, as long as the main body section 22 is assembled in the assembly hole 11 and fixedly sealed to the vent body 1, and the present application takes the bonding and sealing connection between the main body section 22 and the vent body 1 as an example for explanation. Further, the main body section 22 and the vent body 1 are pressed tightly when being bonded, so as to improve the sealing reliability between the main body section 22 and the vent body 1, and reduce the risk of the elastic member 2 falling off from the vent body 1 due to unreliable bonding between the main body section 22 and the vent body 1, thereby improving the exhaust and sealing reliability of the vent.

[0057] The thickness of the main section 22 gradually decreases from the inlet to the outlet 211. This arrangement allows the main section 22 to maintain an arc shape, which is conducive to the elastic member 2 opening quickly under the action of air pressure. When the elastic member 2 is closed, the main section 22 disperses the force to keep the elastic member 2 from being sunken, which is conducive to the water flow quickly flowing over the surface of the elastic member 2 when driving in rainy days or wading. The thickness of the closing section 3 remains unchanged, which can make the force on the closing section 3 consistent, so that the closing section 3 can be closed quickly.

[0058] In some embodiments of the present invention, Figure 1 As shown, the thickness dimension of the closing segment 3 is smaller than the minimum thickness dimension of the main body segment 22 .

[0059] Among them, the thickness dimension of the closing section 3 can be smaller than the minimum thickness dimension of the main body section 22. Such a setting can enable the elastic member 2 to quickly empty the airflow inside the vehicle while ensuring the strength. In addition, further thinning the closing section 3 is conducive to the closing section 3 to quickly open the outlet 211 of the air outlet channel 21 when the pressure in the air outlet channel 21 reaches a preset value, thereby further achieving the effect of quickly emptying the airflow inside the vehicle.

[0060] In some embodiments of the present invention, Figure 1As shown, the main body section 22 has a main body section top wall 221 , and the main body section top wall 221 is formed with a first arc-shaped portion 222 protruding toward the outside of the elastic member 2 , and the first arc-shaped portion 222 is adjacent to the closed section 3 .

[0061] The main body section 22 may have a main body section top wall 221, and the main body section top wall 221 is formed with a first arc-shaped portion 222 protruding toward the outside of the elastic member 2, and the first arc-shaped portion 222 is adjacent to the closed section 3. This is conducive to the rapid opening of the main body section top wall 221 under the action of air pressure, and when the elastic member 2 is closed, the main body section 22 can also disperse the force to keep the first arc-shaped portion 222 from being concave, which is conducive to the rapid flow of water through the outer surface of the first arc-shaped portion 222 when driving in rainy days or wading.

[0062] Specifically, the thickness of the main section 22 and the assembly hole 11 at the assembly point can be set to 0.5mm. The thickness of 0.5mm can maintain the inlet strength of the air outlet channel 21, and can also maintain the overall shape of the air outlet channel 21, reducing the risk of external airflow or water flow blowing the air outlet channel 21 and affecting the flow direction of water. The thickness of the first arc-shaped portion 222 is gradually reduced from 0.5mm to 0.4mm. By gradually weakening the strength of the air outlet channel 21, the airflow in the vehicle can be quickly discharged while maintaining the strength of the air outlet channel 21. The thickness between the first arc-shaped portion 222 and the closed section 3 is gradually reduced from 0.4mm to 0.1mm, further reducing the strength of the air outlet channel 21, so that the main section 22 maintains an arc shape, which is conducive to the elastic member 2 opening quickly under the action of air pressure. When the elastic member 2 is closed, the main section 22 can also disperse the force to keep the elastic member 2 from being concave, which is conducive to the water flow to flow quickly over the surface of the elastic member 2 when driving in rainy days or wading. The closing section 3 maintains a thickness of 0.1 mm unchanged, so that the force applied to the closing section 3 is consistent, and thus the closing section 3 can be closed quickly.

[0063] In some embodiments of the present invention, Figure 3 As shown, the main body section 22 has a main body section bottom wall 223 , and the main body section bottom wall 223 is formed with a second arc-shaped portion 224 protruding toward the inside of the elastic member 2 , and the second arc-shaped portion 224 is adjacent to the closed section 3 .

[0064] Among them, the main body section 22 can have a main body section bottom wall 223, and the main body section bottom wall 223 forms a second arc-shaped portion 224 protruding toward the inside of the elastic member 2, and the second arc-shaped portion 224 is adjacent to the closed section 3. The main body section bottom wall 223 forms a second arc-shaped portion 224 protruding toward the inside of the elastic member 2, which can gradually weaken the outlet 211 of the air outlet channel 21, which is beneficial to maintain the strength of the outlet 211 of the air outlet channel 21 while allowing the airflow inside the vehicle to be quickly discharged outside the vehicle.

[0065] Specifically, the thickness of the main body section bottom wall 223 and the assembly hole 11 can also be set to 0.5mm, and the thickness between the main body section bottom wall 223 and the assembly hole 11 and the second arc-shaped portion 224 can be 10mm. The thickness of the 10mm main body section bottom wall 223 is 0.5mm. The 0.5mm thick main body section bottom wall 223 can maintain the inlet strength of the air outlet channel 21, and can also maintain the overall shape of the air outlet channel 21, reducing the risk of external airflow or water flow blowing the air outlet channel 21 and affecting the flow direction of water. The thickness between the second arc-shaped portion 224 and the closed section 3 is gradually reduced from 0.4mm to 0.1mm, which is conducive to the second arc-shaped portion 224 to maintain the arc shape, so that the elastic member 2 opens quickly under the action of air pressure. When the elastic member 2 is closed, the second arc-shaped portion 224 can also disperse the force to keep the elastic member 2 from being concave, which is conducive to the water flow to flow quickly over the surface of the elastic member 2 when driving in rainy days or wading. The closing section 3 maintains a thickness of 0.1 mm unchanged, so that the force applied to the closing section 3 is consistent, and thus the closing section 3 can be closed quickly.

[0066] A vehicle according to an embodiment of the utility model comprises the air vent of the vehicle of the above embodiment.

[0067] The vent body 1 can be made of hard materials such as PP (polypropylene), and the vent body 1 can be used to support the vent as a whole. A snap-fit ​​buckle 4 can be provided on the vent body 1, and the vent can be snap-fitted with the body sheet metal through the snap-fit ​​buckle 4. A seal 5 can also be provided between the vent body 1 and the body sheet metal. The seal 5 can be made of elastic materials such as TPV (thermoplastic vulcanized rubber). When the vent body 1 and the body sheet metal are snap-fitted, the seal 5 is clamped and clamped between the vent body 1 and the body sheet metal, thereby improving the sealing between the vent body 1 and the body sheet metal, and reducing the risk of the vent body 1 falling off the vehicle. The elastic member 2 can be assembled in the assembly hole 11 of the vent body 1, and the elastic member 2 can be made of soft materials such as silicone and EPDM (ethylene propylene diene monomer).

[0068] By providing the elastic member 2, the outlet 211 of the air outlet channel 21 can be opened and closed automatically. When the vehicle door is closed or the external circulation is turned on, the outlet 211 of the air outlet channel 21 is opened by the pressure inside the vehicle, which is conducive to balancing the air pressure inside and outside the vehicle. When the pressure inside the vehicle disappears, the outlet 211 of the air outlet channel 21 is closed by its own preload force. When the vehicle wades through water, the self-sealing property is increased by relying on the external water flow and air flow, thereby further increasing the sealing property inside the vehicle, improving the wading performance of the vent, reducing the risk of external water vapor and dust entering the vehicle from the air outlet channel 21, and being conducive to protecting the vehicle environment, thereby improving the comfort of the passengers inside the vehicle.
