Description

Technical Field

[0001] This invention belongs to the field of automotive technology. Specifically, this invention relates to a ventilation vent assembly and a vehicle. Background Technology

[0002] With the development of small cars, their ventilation frames are mostly located at the rear of the vehicle due to styling limitations. When the vehicle is driven in the rain or when the air conditioning is on external air circulation, rainwater can easily seep into the car through the ventilation frame blades, causing user complaints.

[0003] Existing waterproofing solutions for ventilation frames mainly achieve this by optimizing their own structure or adding water-blocking and water-guiding structures. Among them, the solution using a combination of double mesh vents will reduce the airtightness of the entire vehicle and cannot block dust; while the solution integrating multiple water-blocking and water-guiding components has a good waterproofing effect, but it has the problems of complex structure and high cost.

[0004] This invention provides a ventilation assembly, particularly concerning how to balance waterproofing and dustproofing with low cost. Summary of the Invention

[0005] This invention aims to at least solve one of the technical problems existing in the prior art. To this end, this invention provides a vent assembly that improves waterproofing and dustproofing while simplifying the product structure and reducing production costs.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a ventilation vent assembly, including a ventilation frame body disposed on the vehicle body and a water baffle disposed on the ventilation frame body, wherein the water baffle is provided with a downwardly inclined drainage surface, and the width of the drainage surface gradually increases from top to bottom;

[0007] The ventilation frame body is provided with at least one ventilation hole, and a blade is provided at the ventilation hole. The blade is rotatably mounted on the ventilation frame body.

[0008] As an improvement to the above solution, the water-blocking member has an upper end and a lower end, the width of the water-blocking member gradually increases from top to bottom, and the drainage surface extends from the upper end to the lower end of the water-blocking member.

[0009] As an improvement to the above solution, the width of the upper end of the water-blocking member is greater than the width of the ventilation frame body, and the width direction of the water-blocking member is parallel to the width direction of the ventilation frame body.

[0010] As an improvement to the above solution, the ventilation frame body is provided with a guide groove, and the water-blocking component is inserted into the guide groove.

[0011] As an improvement to the above solution, the water-blocking component includes a connected mounting part and a diversion part, the diversion surface is disposed on the diversion part, the mounting part is inserted into the guide groove, and the diversion part is inclined relative to the vehicle body height direction.

[0012] As an improvement to the above solution, the width of the drainage section gradually increases from top to bottom.

[0013] As an improvement to the above solution, the ventilation frame body is provided with a limiting structure for limiting the water baffle along the vehicle height direction, and the water baffle is provided with a limiting groove for the limiting structure to be embedded.

[0014] As an improvement to the above solution, the mounting part includes a first snap-fit ​​part and a second snap-fit ​​part. Two second snap-fit ​​parts are provided, and the two second snap-fit ​​parts are respectively fixedly connected to the two ends of the first snap-fit ​​part in the length direction. The limiting groove is provided on the second snap-fit ​​part. Both the first snap-fit ​​part and the second snap-fit ​​part are embedded in the guide groove.

[0015] As an improvement to the above solution, a filter element is provided between the blade and the ventilation hole.

[0016] Accordingly, the present invention also provides a vehicle including the aforementioned air vent assembly.

[0017] The ventilation vent assembly of the present invention, by setting a water-blocking component on the ventilation frame body, partially shields the ventilation frame body, blocking the water flowing down the surface of the vehicle body to the outside of the ventilation frame body, preventing the water from directly reaching the ventilation frame body. The water-blocking component is provided with a downwardly inclined drainage surface, and the water dripping or flowing onto the water-blocking component flows downward along the drainage surface under its own gravity, so that the water is continuously guided and drained away during the downward flow, and will not stagnate on the water-blocking component and cause water accumulation; moreover, the width of the drainage surface gradually increases from top to bottom, and the water flows downward along the drainage surface while dispersing and expanding to both sides, ensuring that the water is discharged in a timely and smooth manner. Meanwhile, the water-blocking component's top-mounted shielding of the ventilation frame body reduces the chance of dust entering the vehicle through the ventilation frame body; thus, it effectively prevents water and dust from entering the vehicle through the ventilation frame body, improving the waterproof and dustproof effect; the water-blocking and drainage functions can be achieved simply by installing a water-blocking component on the ventilation frame body, without modifying the structure of the ventilation frame body itself. The product has fewer parts and a simpler structure, which can reduce production costs. Attached Figure Description

[0030] To make the technical problems, technical solutions, and advantages of this invention clearer, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0031] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention. Furthermore, in the following embodiments, the terms "first" and "second" do not represent an absolute distinction in structure and / or function, nor do they represent a sequential execution order, but are merely for the convenience of description.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the specification of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0033] The technical concept of this invention includes: With the rapid development of the automotive industry, small cars are increasingly favored by consumers due to their flexibility and economic advantages. However, due to the limitations of vehicle styling and overall size, the ventilation frames of such vehicles are usually located at the rear of the vehicle, which is significantly different from the conventional solution of venting frames being located on the left and right rear side panels. When the vehicle's air conditioning is on with external circulation, or when driving on bumpy roads in heavy rain, the ventilation frame blades may accidentally open due to airflow impact and vibration, causing rainwater to enter the vehicle. This may not only damage the vehicle's electrical equipment but also cause user complaints, seriously affecting the driving experience. To address these problems, there are currently two main approaches to waterproofing ventilation frames in related technologies. The first approach is to optimize the structure of the ventilation frame itself. For example, existing technology discloses a waterproof, interconnected rear side panel ventilation vent assembly, which includes a ventilation vent component and side panel sheet metal parts. The ventilation vent assembly is fixedly connected to the side panel sheet metal on one side and to the interior side trim panel on the other side. A mesh-like ventilation hole is provided at the top of the interior side trim panel, and a lower mesh-like ventilation hole is provided on the ventilation vent assembly. The upper and lower vents work together to achieve air pressure balance inside and outside the vehicle. However, this solution uses mesh-like ventilation holes for both the upper and lower vents, resulting in reduced overall vehicle airtightness and ineffective prevention of dust entering the vehicle. A second approach is to add water-blocking and water-guiding structures. For example, existing technology discloses a ventilation frame structure and a ventilation pressure relief structure, which integrates components such as a water storage tank formed by a water-blocking assembly, multi-layer exhaust components, an internal water guide plate, a water channel, and a waterproof trench on the ventilation frame body. While this solution effectively prevents water intrusion, it suffers from complex structure and high manufacturing costs, hindering large-scale application. The technical solution of this invention is as follows:

[0034] Firstly, embodiments of the present invention provide a ventilation vent assembly, which is disposed on the vehicle body, and is particularly suitable for small cars where the ventilation frame is located at the rear of the vehicle body due to shape and size limitations. When the vehicle is driving with the air conditioning on external circulation, on bumpy roads, in heavy rain, or during high-intensity rain, high-pressure cleaning, and transportation, the ventilation vent assembly will be subjected to the impact of water flow from the rear of the vehicle body. The ventilation vent assembly of the present invention, while satisfying the normal ventilation function of the vehicle interior, can effectively prevent water and dust from entering the vehicle interior through the ventilation vents.

[0035] Specifically, such as Figures 1 to 11 As shown, the ventilation vent assembly provided in this embodiment of the invention includes a ventilation frame body 2 disposed on the vehicle body and a water baffle 6 disposed on the ventilation frame body 2. The water baffle 6 is provided with a downwardly inclined drainage surface 604, and the width of the drainage surface 604 gradually increases from top to bottom.

[0036] In this embodiment of the invention, the ventilation frame body 2 is mounted on the rear connecting plate 1 of the side outer panel of the vehicle body. The rear connecting plate 1 of the side outer panel is a sheet metal part on the vehicle body. One ventilation vent assembly 7 is arranged on each of the left and right sides of the vehicle body. Due to the rear structure of the small car, water flowing down from the rear water channel will flow along the rear sheet metal surface to the area where the ventilation frame body 2 is located. If the ventilation frame body 2 lacks a waterproof structure, water will enter the vehicle through the ventilation frame body 2. Therefore, the location and structure of the water-blocking component 6 are the main improvements of the ventilation vent assembly 7 in this embodiment of the invention.

[0037] like Figure 2 , Figures 5 to 8 As shown, the water-blocking component 6 is disposed on the upper part of the ventilation frame body 2. The water-blocking component 6 partially shields the ventilation frame body 2, preventing water flowing down the vehicle body surface from reaching the outside of the ventilation frame body 2 directly. The water-blocking component 6 has a drainage surface 604, which extends obliquely downwards and gradually increases in width from top to bottom. The drainage surface 604 constitutes at least a portion of the outer surface of the water-blocking component 6. Water dripping onto the water-blocking component 6 flows downwards along the obliquely extending drainage surface 604 under its own gravity. Because the width of the drainage surface 604 gradually increases from top to bottom, the water disperses and expands to both sides as it flows downwards along the drainage surface 604, and is promptly guided to the sides of the water-blocking component 6 and discharged outside the vehicle. Water is unlikely to accumulate on the water-blocking component 6, and the water will not cross the water-blocking component 6 and enter the ventilation frame body 2. To promptly drain water dripping onto the water-blocking component 6 and prevent water accumulation, the overall size of the water-blocking component 6 is designed to be larger than the overall size of the ventilation frame body 2. Simultaneously, the water-blocking component 6's top-mounted shielding of the ventilation frame body 2 reduces the chance of dust entering the vehicle interior from the upper part of the ventilation frame body 2. Therefore, the ventilation vent assembly 7 of this embodiment effectively prevents water and dust from entering the vehicle interior through the ventilation frame body 2, avoiding damage to electrical equipment due to water ingress and eliminating user complaints caused by water entering the vehicle. Furthermore, while achieving the aforementioned waterproof and dustproof functions, the ventilation structure of the ventilation frame body 2 itself remains unchanged, and the normal ventilation function of the ventilation vent assembly 7 is unaffected.

[0038] In terms of structural simplification and cost control, the ventilation port assembly 7 of this embodiment only needs to set a water-blocking component 6 on the ventilation frame body 2 to achieve the functions of water blocking and drainage. There is no need to modify the structure of the ventilation frame body 2 itself, nor is it necessary to set up complex water blocking and water guiding structures such as multi-layer exhaust components, internal water guide plates, water inlet channels, and waterproof trenches. The product has fewer parts, a simple structure, and simple manufacturing and assembly processes, thereby effectively reducing the production cost of the product.

[0039] In embodiments of the present invention, such as Figure 2 , Figures 5 to 8As shown, the water-blocking member 6 has an upper end and a lower end. The width of the water-blocking member 6 gradually increases from top to bottom. The drainage surface 604 extends from the upper end to the lower end of the water-blocking member 6. The upper end and the lower end are opposite ends in the height direction of the water-blocking member 6. The inclined extension direction of the drainage surface 604 forms an acute angle with the Z-direction. The distance between the upper end of the drainage surface 604 and the ventilation frame body 2 is smaller than the distance between the lower end of the drainage surface 604 and the ventilation frame body 2. Thus, the drainage surface 604 covers the entire outer surface area of ​​the water-blocking member 6 from the upper end to the lower end, forming a continuous, downward-sloping guide surface. Water dripping or flowing onto the water-blocking member 6 from the upper end flows downward and to both sides along the drainage surface 604. After flowing along the drainage surface 604 to the lower end, the water is directly discharged outside the vehicle without dripping onto the ventilation frame body 2.

[0040] Furthermore, the width of the upper end of the water-blocking component 6 is greater than the width of the ventilation frame body 2, and the width of the lower end of the water-blocking component 6 is greater than the width of the upper end of the water-blocking component 6. The width direction of the water-blocking component 6 is parallel to the width direction of the ventilation frame body 2 and parallel to the Y-direction. In this way, it can be ensured that the water flowing down the vehicle body will first contact the water-blocking component 6 instead of the ventilation frame body 2. The water-blocking component 6 provides a good shielding effect on the ventilation frame body 2, blocking the water flowing down the rear sheet metal surface above the ventilation frame body 2 and diverting it downwards.

[0041] In this embodiment of the invention, the water-blocking component 6 has a trapezoidal cross-section that is narrower at the top and wider at the bottom along the height direction of the vehicle body. For example... Figure 5 and Figure 6 As shown, Figure 5 This is a front view of the water-blocking component 6. Figure 6 This diagram shows the Y-direction cross-section of the water deflector 6, illustrating the dimensional design requirements for its upper and lower parts. Specifically, the width dimension L1 of the upper end of the water deflector 6 is 76mm, the length dimension B1 (i.e., the upper thickness of the water deflector 6) along the vehicle body is 12mm, and the chamfer radius R on both sides of the water deflector 6 along the width direction of the vehicle body is 10mm. The width dimension L2 of the lower end of the water deflector 6 is 110mm, and the length dimension B2 (i.e., the lower thickness of the water deflector 6) along the length direction of the vehicle body is 20mm. The dimensional difference between the upper and lower ends of the water deflector 6 creates an inclined angle on its outer surface. The narrower-at-the-top and wider-at-the-bottom structure of the water deflector 6 allows water to flow downwards more effectively. Through the different widths at both ends and the inclined angles at the top and bottom, the water deflector 6 guides the water flow to both sides and discharges it outside the vehicle. The drainage surface 604 extends sloping downwards and its width gradually increases from top to bottom. The overall width of the water-blocking component 6 also gradually increases from top to bottom. The maximum width of the drainage surface 604 is also the maximum overall width of the water-blocking component 6.

[0042] In embodiments of the present invention, such as Figure 2 , Figures 5 to 11 As shown, the ventilation frame body 2 is provided with a guide groove, which is specifically located on the upper part of the ventilation frame body 2. The water-blocking component 6 is inserted into the guide groove, and the surface of the water-blocking component 6 is in close contact with the groove wall, making it difficult to loosen. The water-blocking component 6 is assembled by insertion, which is simple to operate and does not require tools or fasteners. The water-blocking component 6 and the groove wall of the guide groove form a zero-gap insertion fit, ensuring the stability and installation strength of the water-blocking component 6 and preventing the water-blocking component 6 from loosening or shifting during vehicle vibration.

[0043] Furthermore, such as Figure 2 , Figures 5 to 11 As shown, the water-blocking component 6 includes a connected mounting portion and a diversion portion 603. A diversion surface 604 is disposed on the diversion portion 603. The mounting portion is inserted into a guide groove. The diversion portion 603 is inclined relative to the vehicle body height direction. The inclined extension direction of the diversion portion 603 forms an acute angle with the Z-direction. The width of the diversion portion 603 gradually increases from top to bottom. Figure 6 As can be seen in the Y-direction section, the drainage section 603 is inclined relative to the Y-direction, thus forming a drainage surface 604 extending inclinedly from top to bottom. The drainage surface 604 is the side surface of the drainage section 603 facing away from the mounting section. Thus, the water-blocking member 6 forms a structure with separate installation and drainage sections. The mounting section ensures reliable connection between the water-blocking member 6 and the ventilation frame body 2, while the drainage section 603 ensures smooth drainage. The mounting section and the drainage section 603 are connected and together constitute the complete water-blocking member 6.

[0044] In this embodiment of the invention, the ventilation frame body 2 is provided with a limiting structure for the water baffle 6 along the vehicle height direction to ensure that the water baffle 6 is in the correct installation position and is not easily loosened. Correspondingly, the water baffle 6 is provided with a limiting groove for the limiting structure to be embedded in. The limiting groove is specifically a groove provided on the mounting part. The inner side of the mounting part fits against the ventilation frame body 2, and the groove is formed on the inner side. When the water baffle 6 is assembled with the ventilation frame body 2, the mounting part moves from top to bottom along the guide groove at the top of the ventilation frame body 2 and is completely embedded in the guide groove at the top of the ventilation frame body 2. At the same time, the limiting structure is embedded in the limiting groove on the water baffle 6, thus achieving the positioning of the water baffle 6 in the vehicle width direction and length direction, as well as the limiting in the vehicle height direction. The installation is simple and convenient, the water baffle 6 is firmly installed, and the water baffle 6 will not loosen or move during vehicle driving vibration.

[0045] Furthermore, such as Figure 2 , Figures 4 to 11As shown, the limiting structure mainly includes limiting blocks 202. Limiting blocks 202 are mainly located at both ends of the ventilation frame body 2 in the width direction. Each limiting block 202 is a protruding structure on a plane of the ventilation frame body 2 that contacts the water-blocking component 6. The limiting blocks 202 are located below the guide groove, and at least two limiting blocks 202 are provided, with at least one limiting block 202 at each end of the width direction of the ventilation frame body 2. During assembly, after the mounting part is fully embedded in the upper guide groove of the ventilation frame body 2, each limiting block 202 on the ventilation frame body 2 is embedded into the corresponding limiting groove on the water-blocking component 6. At this time, the limiting blocks 202 limit the water-blocking component 6 in the vehicle height direction. Through the cooperation of the guide groove and the limiting structure, the water-blocking component 6 is not easily detached from the ventilation frame body 2, resulting in good installation stability. Figure 10 As shown in the Y-direction section, after the limiting block 202 is embedded in the limiting groove of the water baffle 6, the upper end of the limiting block 202 is located below the top surface of the limiting groove, and the lower end of the limiting block 202 is located above the bottom surface of the limiting groove. The distance S4 between the upper end of the limiting block 202 and the top surface of the limiting groove along the vehicle height direction is 0.4~0.6mm, and the distance S5 between the lower end of the limiting block 202 and the bottom surface of the limiting groove along the vehicle height direction is 0.2~0.4mm. This limiting distance ensures that the water baffle 6 does not detach from the ventilation frame body 2 after being inserted into place, and also reserves the necessary assembly tolerance for the water baffle 6 to avoid assembly interference caused by over-positioning.

[0046] In one specific embodiment of the present invention, two limiting blocks 202 are provided, both at the same height, and respectively located at both ends of the ventilation frame body 2 in the width direction. For example, after the limiting blocks 202 are embedded in the limiting groove of the water-blocking member 6, the distance S4 between the upper end of the limiting block 202 and the top surface of the limiting groove along the vehicle height direction can be set to 0.41mm, 0.43mm, 0.44mm, 0.46mm, 0.48mm, 0.50mm, 0.52mm, 0.54mm, 0.56mm, or 0.58mm. The distance S5 between the lower end of the limiting block 202 and the bottom surface of the limiting groove along the vehicle height direction can be set to 0.21mm, 0.23mm, 0.24mm, 0.26mm, 0.28mm, 0.30mm, 0.32mm, 0.34mm, 0.36mm, or 0.38mm.

[0047] In embodiments of the present invention, such as Figure 2 , Figures 5 to 11As shown, the mounting part has an overall U-shaped structure, which matches the shape of the guide groove on the ventilation frame body 2. The mounting part is embedded in the guide groove and fits tightly with it. Specifically, the mounting part includes a first snap-fit ​​part 601 and a second snap-fit ​​part 605. The first snap-fit ​​part 601 and the second snap-fit ​​part 605 are fixedly connected. Two second snap-fit ​​parts 605 are provided, and the two second snap-fit ​​parts 605 are respectively located on opposite sides of the first snap-fit ​​part 601. The two second snap-fit ​​parts 605 are respectively fixedly connected to the two ends of the first snap-fit ​​part 601 in the length direction. The length direction of the first snap-fit ​​part 601 is parallel to the Y direction. The two second snap-fit ​​parts 605 extend downward toward the first snap-fit ​​part 601. The first snap-fit ​​part 601 and the second snap-fit ​​part 605 are block-shaped structures. A limiting groove is provided on the second snap-fit ​​part 605, and the limiting groove is a groove that penetrates the second snap-fit ​​part 605 along the thickness direction of the second snap-fit ​​part 605. When the water-blocking component 6 is assembled with the ventilation frame body 2, the first snap-fit ​​part 601 and the two second snap-fit ​​parts 605 are embedded in the guide groove. The guide groove is a rectangular groove provided on the ventilation frame body 2. The first snap-fit ​​part 601 and the second snap-fit ​​part 605 are tightly fitted with the guide groove.

[0048] The mounting section has an overall U-shaped structure. The first snap-fit ​​part 601 and the two second snap-fit ​​parts 605 together form the three mating sides of the U-shaped mounting section. After the mounting section is embedded in the guide groove, the three mating sides abut against the corresponding inner wall surfaces of the guide groove, forming a large number of mating surfaces and a large mating area. The degrees of freedom of the mounting section along the vehicle height direction, vehicle width direction, and vehicle length direction are all constrained, resulting in high connection strength. The first snap-fit ​​part 601 and the second snap-fit ​​part 605 are tightly fitted with the guide groove, forming a zero-gap fit. There is no channel for water flow at the fit gap, and water cannot seep into the ventilation frame body 2 along the joint between the mounting section and the guide groove. The water-blocking part 6 forms a complete closed water-blocking area. At the same time, the zero-gap fit eliminates the swaying space of the water-blocking part 6 in the guide groove. When the vehicle vibrates during driving, the water-blocking part 6 does not move or produce abnormal noise. The limiting groove is located on the mounting part, and the limiting structure is basically not exposed, thus not damaging the integrity of the flow guiding surface 604. The outer surface of the water-blocking component 6 remains continuous and smooth, and the water flow guiding effect is not disturbed. Under the condition of limited overall size of the water-blocking component 6, the arrangement of the mounting part and the flow guiding part 603 ensures that the connection function and the flow guiding function of the water-blocking component 6 do not interfere with each other. Reliable connection on the ventilation frame body 2 is achieved with a small structural volume, and efficient flow guiding effect is achieved.

[0049] like Figure 2 , Figures 5 to 11As shown, the installation part also includes a connecting part 602, which is fixedly connected to the first snap-fit ​​part 601 and the second snap-fit ​​part 605. The connecting part 602 is also fixedly connected to the drainage part 603. The connecting part 602 is located between the first snap-fit ​​part 601, the second snap-fit ​​part 605 and the drainage part 603. The connecting part 602 is located above the guide groove and is not embedded in the guide groove. The connecting part 602 has a U-shaped structure. The connecting part 602 covers the guide groove below. The connecting part 602 extends from the upper end of the drainage part 603 to the lower end of the drainage part 603, forming a good shielding effect on the ventilation frame body 2 above and on both sides of the guide groove.

[0050] In embodiments of the present invention, such as Figure 2 and Figure 7 As shown, the ventilation frame body 2 is provided with at least one ventilation hole 203. All ventilation holes 203 are arranged sequentially along the height direction of the vehicle body on the ventilation frame body 2. Each ventilation hole 203 is provided with a blade 4, which is rotatably mounted on the ventilation frame body 2. The rotation center line of the blade 4 is parallel to the width direction of the vehicle body. The blade 4 can rotate up and down to control the opening and closing of the ventilation hole 203. When the vehicle's air conditioning is turned on with external circulation, the blade 4 rotates upward and opens the ventilation hole 203, allowing airflow to pass through the ventilation hole 203, achieving air exchange and air pressure balance between the inside and outside of the vehicle. When the blade 4 is closed, the ventilation hole 203 is blocked by the blade 4, reducing the direct entry of dust and moisture into the vehicle through the ventilation hole 203.

[0051] Furthermore, such as Figure 2 and Figure 7 As shown, a filter element 5 is installed between the blade 4 and the ventilation hole 203. The filter element 5 is fixedly installed on the ventilation frame body 2 and is located on the airflow channel. The filter element 5 is densely covered with small holes, and airflow can pass through the pores of the filter element 5. While ensuring the normal flow of air exchange, the filter element 5 intercepts dust in the airflow, preventing some dust from entering the ventilation hole 203, reducing the amount of dust entering the vehicle, and thus improving the dustproof capability of the ventilation assembly 7.

[0052] In this embodiment of the invention, the filter element 5 is a non-woven fabric made of PET material, and is snap-fitted to the ventilation frame body 2. The non-woven fabric has a porous structure, allowing airflow to pass through its pores. While ensuring normal airflow, the non-woven fabric also intercepts dust in the airflow, preventing some dust from entering the ventilation hole 203 and reducing the amount of dust entering the vehicle. Simultaneously, the non-woven fabric is soft, and when the blades 4 close, they contact the non-woven fabric, which cushions the movement of the blades 4, reducing the collision noise generated between the blades 4 and the ventilation frame body 2 during closure and preventing noise transmission into the vehicle. The ventilation assembly 7 ensures normal ventilation while guaranteeing dustproof and noise reduction performance, and the overall vehicle airtightness and ride comfort are not affected by the ventilation opening configuration.

[0053] In one specific embodiment of the present invention, such as Figure 2 and Figure 7 As shown, the ventilation hole 203 is a rectangular hole, and the filter element 5 is also rectangular. The length of the filter element 5 is 66±0.5mm, the width is 27.3±0.3mm, and the thickness is 0.55mm. The blade 4 is made of EPDM (ethylene propylene diene monomer) material, with a length of 66±0.5mm, a width of 27.3±0.3mm, and a thickness of 0.4mm. The blade 4 and the non-woven fabric are assembled onto the ventilation frame body 2 manually. The assembly process is simple and suitable for mass production.

[0054] In another specific embodiment of the present invention, such as Figure 2 and Figure 7 As shown, three ventilation holes 203 are provided on the ventilation frame body 2. The three ventilation holes 203 are arranged sequentially along the height of the vehicle body on the ventilation frame body 2. The three ventilation holes 203 correspond to the smaller blades 4. The blades 4 are subjected to less force and can open and close flexibly. When the blades 4 repeatedly open and close during vehicle operation, the impact kinetic energy of a single blade 4 is small. Combined with the buffering effect of the non-woven fabric, the noise generated during opening and closing can be effectively controlled. Moreover, the multiple ventilation holes 203 are redundant, resulting in high ventilation reliability. When any one of the ventilation holes 203 is blocked by dust or foreign objects, the remaining ventilation holes 203 can still maintain the ventilation function. The ventilation capacity of the ventilation port assembly 7 is not lost due to partial blockage, and the compatibility between protective performance and ventilation performance is better.

[0055] In embodiments of the present invention, such as Figure 2 , Figure 7 , Figure 8 , Figure 10 and Figure 11 As shown, mounting holes are provided on the rear connecting plate 1 of the side outer panel of the vehicle body, and the ventilation frame body 2 is installed in the mounting holes. The mounting holes on the rear connecting plate 1 of the side outer panel adopt a countersunk hole design. The dimension h of the mounting hole along the height direction of the vehicle body is 100±0.3mm, and the dimension L3 along the width direction of the vehicle body is 75±0.3mm. To ensure installation strength, the thickness t1 of the rear connecting plate 1 of the side outer panel of the vehicle body is greater than or equal to 0.65mm. The countersunk hole design provides an installation positioning reference for the ventilation frame body 2, and at the same time ensures that the sealing element 3 fully fits against the periphery of the hole of the rear connecting plate 1 of the side outer panel of the vehicle body.

[0056] In embodiments of the present invention, such as Figures 1 to 3As shown, the ventilation frame body 2 is connected to the rear connecting plate 1 of the side outer panel of the vehicle body via a snap-fit ​​component 201, which engages with the mounting hole. Specifically, there are two snap-fit ​​components 201, located at the upper and lower parts of the ventilation frame body 2, respectively. During assembly, force is applied from both top and bottom directions to press the ventilation frame body 2 into the mounting hole, and the snap-fit ​​component 201 engages with the hole wall, thus achieving a fixed connection between the ventilation frame body 2 and the rear connecting plate 1 of the side outer panel of the vehicle body. The limiting distance S2 between the snap-fit ​​component 201 and the ventilation frame body 2 is 4.3 ± 0.3 mm. This limiting distance matches the thickness of the rear connecting plate 1 of the side outer panel of the vehicle body, ensuring that the snap-fit ​​component 201 reliably engages with the mounting hole and presses the sealing element 3 between the ventilation frame body 2 and the rear connecting plate 1 of the side outer panel of the vehicle body.

[0057] In embodiments of the present invention, such as Figure 2 , Figure 7 , Figure 8 and Figure 11 As shown, a sealing element 3 is provided between the ventilation frame body 2 and the rear connecting plate 1 of the side outer panel of the vehicle body. The sealing element 3 is made of TPE material, which has both corrosion resistance and high temperature resistance, adapting to the high temperature environment and rainwater erosion environment of the rear area of ​​the vehicle. The sealing element 3 is integrated into the ventilation frame body 2 through injection molding, simplifying the manufacturing process of the ventilation port assembly 7. The thickness S3 of the sealing element 3 is 4.8±0.3mm. The sealing element 3 is compressed between the ventilation frame body 2 and the rear connecting plate 1 of the side outer panel of the vehicle body, and the compression amount is greater than or equal to 75%. After compression, the sealing element 3 fits tightly against the ventilation frame body 2 and the rear connecting plate 1 of the side outer panel of the vehicle body, ensuring the sealing effect between the perimeter of the ventilation frame body 2 and the rear connecting plate 1 of the side outer panel of the vehicle body, preventing water from seeping into the vehicle interior through the installation gaps of the ventilation frame body 2. The dimension of the sealing element 3 along the height direction of the vehicle body is 120±0.5mm, and the dimension of the sealing element 3 along the width direction of the vehicle body is 90±0.5mm.

[0058] In this embodiment of the invention, the ventilation frame body 2 is made of PP (polypropylene) material. The ventilation frame body 2 has a dimension of 117mm along the height direction of the vehicle body and a dimension of 97mm along the width direction of the vehicle body. PP material has good molding performance and structural strength. The ventilation frame body 2 serves as the skeleton component of the ventilation port assembly 7, and structures such as guide grooves, limiting structures, snap-fit ​​parts 201, and ventilation holes 203 are all integrated on the ventilation frame body 2.

[0059] The vehicle body is equipped with the aforementioned ventilation vent assembly 7. When the vehicle is driven in rainy weather, due to the insufficient depth of the groove in the rear connecting plate 1 of the side outer panel, water from the rear of the vehicle body cannot be completely drained through the groove. Some water drips onto the water-blocking component 6 of the ventilation vent assembly 7 through the rear water channel, taillight mounting plate, and rear connecting plate 1 of the side outer panel. The water dripping onto the water-blocking component 6 is confined to the drainage surface 604. As the drainage surface 604 extends downwards at an angle and its width gradually increases from top to bottom, the water flows downwards and to both sides along the drainage surface 604 under the action of gravity and flow inertia, and is finally discharged outside the vehicle through the lower end of the water-blocking component 6. Throughout the process, water will not accumulate on the water-blocking component 6, nor will it cross or bypass the water-blocking component 6 to enter the ventilation frame body 2, thus achieving effective waterproof protection for the vehicle interior during rainy weather driving, high-pressure cleaning, and transportation. Similarly, when the vehicle is driving on a bumpy road, even if the blade 4 is opened due to airflow and vibration, the water dripping onto the water deflector 6 will be guided out by the drainage surface 604 and will not enter the vehicle.

[0060] Secondly, embodiments of the present invention also provide a vehicle including a ventilation vent assembly 7 with the above-described structure. This ventilation vent assembly 7 can be referred to... Figures 1 to 11 Further details are omitted here. The ventilation vent assembly 7 is located at the rear of the vehicle, with one vent on each of the left and right sides of the vehicle body. The two ventilation vent assemblies 7 work together to achieve air exchange and air pressure balance between the inside and outside of the vehicle. The vehicle can be a small car or similar model. Because the vehicle of the present invention includes the ventilation vent assembly 7 in the above embodiments, it possesses all the advantages of the aforementioned ventilation vent assembly 7.

The X direction is parallel to the length direction of the vehicle body, the Y direction is parallel to the width direction of the vehicle body, and the Z direction is perpendicular to the X and Y directions.
