Description

Technical Field

[0001] This invention relates to the field of vehicles, and more particularly to a ventilation structure and vehicle, especially to a roof ventilation structure and vehicle suitable for the sunroof location. Background Technology

[0002] Fixed sunroofs are currently the most frequently used sunroof design in vehicles. Their glass is fixed to the vehicle body using an adhesive process. They are characterized by a large opening, a large area exposed to direct sunlight, and the inability to be opened. Compared to traditional roofs (especially those with sunshades), fixed sunroofs suffer from poor heat insulation and sun protection, noticeable heat on the roof, and limited air circulation. To address these issues, existing technologies primarily employ the following measures:

[0003] I. Regular Window Tinting: This involves applying a PET functional film to the surface of car windows, providing functions such as heat insulation, heat preservation, UV blocking, glare reduction, decoration, improved privacy, and safety against explosions. While window tinting can alleviate the problem of overheating on the car roof to some extent, it also suffers from various issues, including a wide variety of types, inconsistent product quality, poor weather resistance, and susceptibility to bubbling, peeling, and spontaneous breakage. The results are not ideal, and it does not fundamentally solve the problem of poor air circulation around the car roof.

[0004] II. Dark Privacy Gray Glass: Dark privacy gray glass, when used in car sunroofs, offers approximately a 6% improvement in heat insulation compared to ordinary glass. While providing significantly better heat insulation than regular glass, it also avoids the increased risk of spontaneous breakage associated with ordinary gray window film. However, due to its darker color and lower light transmittance, it can create a depressing and stuffy driving experience for passengers, and it doesn't fundamentally solve the problem of poor air circulation around the roof.

[0005] Third, increase the air conditioning power or open the side windows. However, most of the air vents in existing in-vehicle air conditioning systems are concentrated in the center console and armrest, with the airflow height parallel to or below the passenger's chest. This lack of adequate ventilation for the head space above the chest results in poor air circulation inside the vehicle, which can easily cause discomfort. In addition, although opening the side windows can increase air circulation, wind noise is significant at high speeds, making it impossible to open the side windows and limiting their use.

[0006] There is currently no effective solution to the problem of poor ventilation and air exchange at the top of the vehicle, which reduces the comfort of the vehicle.

[0007] Therefore, based on years of experience and practice in related industries, the inventor proposes a ventilation structure and vehicle to overcome the shortcomings of existing technologies. Summary of the Invention

[0008] The purpose of this invention is to provide a ventilation structure and vehicle that, under the action of pressure difference, can drive the air between the vehicle body structure and interior parts to flow rapidly into the vehicle, thereby driving a large-scale flow of air inside the vehicle (especially the air in the head space of the passengers), accelerating the heat exchange rate at the roof position, improving the blowing and ventilation effect of the vehicle roof, reducing the temperature inside the vehicle, and improving passenger comfort.

[0013] The second flow channel has at least a second air outlet and a second air inlet. The second air inlet is used to communicate with the interior space of the vehicle, and the second air outlet is connected to the low-pressure area. Through the pressure difference between the second flow channel and the low-pressure area, the air in the interior space of the vehicle passes through the second air inlet and the second flow channel in sequence and is blown out from the second air outlet.

[0014] In a preferred embodiment of the present invention, at least the portion of the first flow channel near the first air outlet gradually increases in width and gradually decreases in height, so that the first air outlet is in a flat, constricted shape.

[0049] To provide a clearer understanding of the technical features, objectives, and effects of the present invention, specific embodiments of the present invention will now be described with reference to the accompanying drawings.

[0050] Implementation Method 1

[0051] like Figures 1 to 7 As shown, the present invention provides a ventilation structure, which includes a first flow channel 1 and a second flow channel 3. The first flow channel 1 has at least a first air outlet 101 and a first air inlet 102. The first air inlet 102 is used to communicate with an air storage space 503 located in the vehicle body structure 5. A drive device 2 is provided in the first flow channel 1 to blow air from the air storage space 503 through the first air inlet 102 and the first flow channel 1 in sequence and out of the first air outlet 101. Along the air flow direction in the first flow channel 1, at least close to the first air outlet 3, a drive device 2 is provided. The first flow channel 1 of the outlet 101 is narrowed to form a low-pressure area at or near the first air outlet 101; the second flow channel 3 has at least a second air outlet 301 and a second air inlet 302. The second air inlet 302 is used to communicate with the interior space of the vehicle, and the second air outlet 301 is connected to the low-pressure area. Through the pressure difference between the second flow channel 3 and the low-pressure area, the air in the interior space of the vehicle passes through the second air inlet 302 and the second flow channel 3 in sequence and is blown out from the second air outlet 301.

[0052] The ventilation structure of this invention includes a first flow channel 1 and a second flow channel 3. The first air inlet 102 of the first flow channel 1 is connected to an air storage space 503 located in the vehicle body structure 5. A driving device 2 installed in the first flow channel 1 can drive the air in the air storage space 503 to sequentially pass through the first air inlet 102 and the first flow channel 1 and be blown out through the first air outlet 101. Along the airflow direction within the first flow channel 1, since at least a portion of the first flow channel 1 near the first air outlet 101 is constricted (this portion of the first flow channel 1 can be a section of the first flow channel 1 directly connected to the first air outlet 101, or a section of the first flow channel 1 near the first air outlet 101, or even the entire first flow channel 1 being constricted), when air is blown out through the first air outlet 101, according to Bernoulli's effect... (The flow rate of the fluid is negatively correlated with the pressure) This can create a low-pressure area at or near the first air outlet 101. The pressure in this low-pressure area is lower than that in the second flow channel 3 and the interior space of the vehicle. Since the second air inlet 302 of the second flow channel 3 is connected to the interior space of the vehicle, and the second air outlet 301 of the second flow channel 3 is connected to the low-pressure area, a pressure difference will be formed between the second flow channel 3 and the low-pressure area. Under the action of the pressure difference, the air in the interior space of the vehicle can be driven to pass through the second air inlet 302 and the second flow channel 3 in sequence and be blown out at a relatively fast speed from the second air outlet 301. This can drive a large-scale flow of air in the vehicle (especially the air in the roof space), accelerate the heat exchange rate, reduce the interior temperature, and improve the comfort of passengers.

[0053] In an optional embodiment of the present invention, such as Figures 1 to 3 , Figures 5 to 7 As shown, at least the portion of the first flow channel 1 near the first air outlet 101 gradually increases in width and gradually decreases in height, so that the first air outlet 101 is in a flat, constricted shape. This increases the air outlet range of the first air outlet 101 in the width direction, thereby increasing the coverage area of ​​the low-pressure area, accelerating the heat exchange rate inside the vehicle, and ensuring a good ventilation and cooling experience for passengers.

[0054] Furthermore, the ratio of the height of the first air outlet 101 to the height of the second air outlet 301 is 2:1 to 1:3. Within this ratio range, the air in the second flow channel 3 can be blown out with maximum efficiency, ensuring the best blowing effect.

[0055] In an optional embodiment of the present invention, such as Figure 1 , Figure 2 As shown, the ventilation structure includes a baffle 4, which is disposed below the vehicle body structure 5, forming a first flow channel 1 between the vehicle body structure 5 and the baffle 4.

[0056] Specifically, such as Figure 1 , Figure 2As shown, the vehicle body structure 5 includes a glass 501 disposed at the vehicle roof and a sheet metal part 502 connected to the glass 501. A first flow channel 1 is formed between the sheet metal part 502 and the partition 4. A drive device 2 is connected to the sheet metal part 502 and / or the partition 4. The connection method between the drive device 2 and the sheet metal part 502 and / or the partition 4 may be, but is not limited to, bonding.

[0057] Furthermore, such as Figure 1 As shown, the sheet metal part 502 is bonded and fixed to the glass 501 by at least one adhesive block 7.

[0058] Furthermore, such as Figure 1 As shown, the air storage space 503 includes at least the gap between the sheet metal part 502 and the glass 501 and / or the vehicle roof.

[0059] Furthermore, such as Figure 1 , Figure 2 As shown, a vehicle interior trim 6 is provided below the partition 4. A second flow channel 3 is formed between the partition 4 and the vehicle interior trim 6. The partition 4 separates the first flow channel 1 and the second flow channel 3, which can prevent air cross-flow between the first flow channel 1 and the second flow channel 3, and also allow the first flow channel 1 and the second flow channel 3 to be close together. Since there is also air in the second flow channel 3, the air in the second flow channel 3 is passively blown out from the second air outlet 301 under the action of the pressure difference between the second flow channel 3 and the low-pressure area, thereby driving a large-scale flow of air in the vehicle, accelerating the heat exchange rate, effectively reducing the temperature inside the vehicle, and improving the comfort of passengers.

[0060] In this embodiment, as Figure 1 As shown, the partition 4, interior trim 6, and drive unit 2 are all located inside the vehicle. Sheet metal part 502 is fixedly installed on the inner side of glass 501. The partition 4 is located below the sheet metal part 502, thereby forming a first flow channel 1 between the bottom of the sheet metal part 502 and the top surface of the partition 4. The drive unit 2 is disposed between the sheet metal part 502 and the partition 4. The top of the drive unit 2 is connected to the bottom of the sheet metal part 502 and / or the bottom of the drive unit 2 is connected to the top surface of the partition 4, thereby fixing the drive unit 2. Interior trim piece 6 is located below partition 4, thus forming a second flow channel 3 between the bottom surface of partition 4 and the top surface of interior trim piece 6. The second flow channel 3 is adjacent to the first flow channel 1 (separated only by partition 4). In the air outlet direction of the second flow channel 3, the second flow channel 3 can bend or tilt towards the first air outlet 101 of the first flow channel 1, thereby allowing the second air outlet 301 of the second flow channel 3 to approach the first air outlet 101 of the first flow channel 1, ensuring that air within the second flow channel 3 is blown out smoothly. The terms "upper," "lower," "top," and "bottom," which indicate direction, are used only for ease of understanding. Figure 1The description and understanding of the structure shown is not intended to limit the actual directions of each structural component, such as top, bottom, and upper part.

[0061] In this invention, the first flow channel 1 can be positioned above the second flow channel 3 (i.e., the first flow channel 1 is closer to the vehicle body structure 5 than the second flow channel 3). Alternatively, the first flow channel 1 can be positioned below the second flow channel 3 (i.e., the second flow channel 3 is closer to the vehicle body structure 5 than the first flow channel 1), as in another optional embodiment of this invention. Figure 6 , Figure 7 As shown, the ventilation structure includes a baffle 4, forming a second flow channel 3 between the vehicle body structure 5 and the baffle 4.

[0062] Specifically, such as Figure 6 , Figure 7 As shown, the vehicle body structure 5 includes a glass 501 disposed at the vehicle roof and a sheet metal part 502 connected to the glass 501. A second flow channel 3 is formed between the sheet metal part 502 and the partition 4, and the interior trim 6 of the vehicle is located below the partition 4. A first flow channel 1 is formed between the partition 4 and the interior trim 6 of the vehicle. A drive unit 2 is connected to the interior trim 6 and / or the partition 4 of the vehicle. The connection method between the drive unit 2 and the interior trim 6 and / or the partition 4 of the vehicle may be, but is not limited to, bonding.

[0063] In this embodiment, as Figure 6 As shown, the partition 4, interior trim 6, and drive unit 2 are all located inside the vehicle. Sheet metal part 502 is fixedly installed on the inner side of glass 501. The partition 4 is located below the sheet metal part 502, thus forming a second flow channel 3 between the bottom of the sheet metal part 502 and the top surface of the partition 4. The interior trim 6 is located below the partition 4, thus forming a first flow channel 1 between the bottom surface of the partition 4 and the top surface of the interior trim 6. The second flow channel 3 is adjacent to the first flow channel 1 (the second flow channel 3 and the first flow channel 1 are separated only by the partition 4). In the air outlet direction of the first flow channel 1, the first flow channel 1 can bend or tilt towards the second air outlet 301 of the second flow channel 3, so that the first air outlet 101 of the first flow channel 1 can be close to the second air outlet 301 of the second flow channel 3, so as to ensure that the air in the second flow channel 3 is blown out smoothly. The drive unit 2 is positioned between the partition 4 and the interior trim 6. The top of the drive unit 2 is connected to the bottom surface of the partition 4, and / or the bottom of the drive unit 2 is connected to the top of the interior trim 6, thereby fixing the drive unit 2 in place. The terms "up," "down," "top," and "bottom," which indicate direction, are used solely for ease of understanding. Figure 6 The description and understanding of the structure shown is not intended to limit the actual directions of each structural component, such as top, bottom, and upper part.

[0064] In an optional embodiment of the present invention, the driving device 2 is a fan. Preferably, the driving device 2 is a bladeless fan, which features high safety, low noise, and stable airflow. It also solves the problem of poor air circulation on the vehicle roof, reducing the roof air temperature to some extent, thereby reducing the energy consumption of air conditioning and improving passenger comfort. The bladeless fan is an existing device, and its specific structure is not limited here.

[0065] In an optional embodiment of the present invention, such as Figure 5 As shown, a circulation port 8 is also provided between the two connected ventilation structures. The circulation port 8 is connected to the air storage space 503. Air in the vehicle interior can enter the air storage space 503 through the circulation port 8. Thus, while the air in the air storage space 503 is being blown out, the air in the air storage space 503 can be replenished, ensuring the continuous and stable operation of the ventilation structure.

[0066] Furthermore, an air intake device (not shown) or an air blowing device (not shown) is provided in the air storage space 503 or at the circulation port 8 to drive air from the vehicle interior space into the air storage space 503. The air intake device or the air blowing device provides a certain suction or blowing force to allow air from the vehicle interior space to enter the air storage space 503, thereby improving the air flow in the vehicle interior space and ensuring that air from the vehicle interior space can smoothly enter the air storage space 503.

[0067] The features and advantages of the ventilation structure of the present invention are:

[0068] With the arrangement of the first flow channel 1 and the second flow channel 3, a drive device 2 is installed in the first flow channel 1. Along the air flow direction in the first flow channel 1, since at least the part of the first flow channel 1 near the first air outlet 101 is constricted, a low-pressure area can be formed at or near the first air outlet 101 of the first flow channel 1 according to the Bernoulli effect when air is blown out from the first air outlet 101 of the first flow channel 1. Since the second air inlet 302 of the second flow channel 3 is connected to the vehicle interior space, and the second air outlet 301 of the second flow channel 3 is connected to the low-pressure area, a pressure difference will be formed between the second flow channel 3 and the low-pressure area. Under the action of the pressure difference, the air in the vehicle interior space can be driven to pass through the second air inlet 302 and the second flow channel 3 in sequence and be blown out at a relatively fast speed from the second air outlet 301 of the second flow channel 3. This can drive a large-scale airflow in the vehicle, accelerate the heat exchange rate, reduce the temperature inside the vehicle, and improve the comfort of the passengers.

[0069] Implementation Method 2

[0070] like Figure 4 , Figure 5As shown, the present invention provides a vehicle, which includes a vehicle body 10 and a plurality of the above-mentioned ventilation structures 20. The plurality of ventilation structures 20 are disposed on the top of the vehicle body 10, thereby enabling heat exchange and cooling of the vehicle top (such as sunroof), so that after the vehicle is exposed to high temperature and sun, the comfort of the head of the passengers can be quickly restored after using the ventilation structures 20, thus improving the driving experience.

[0071] In an optional embodiment of the present invention, such as Figure 4 As shown, a sunroof is provided on the top of the vehicle body 10. The sunroof includes glass 501, and multiple ventilation structures 20 are provided on the edge of glass 501. The multiple ventilation structures 20 are spaced apart and evenly distributed along the circumference of glass 501.

[0072] Furthermore, the spacing between two adjacent ventilation structures 20 is 100mm to 300mm. Since two adjacent ventilation structures 20 are separated by a partition plate, the distance between two adjacent partition plates can also be 100mm to 300mm.

[0073] The vehicle of the present invention has the features and advantages of the above-mentioned ventilation structure, which will not be repeated here.

[0074] The above description is merely an illustrative embodiment of the present invention and is not intended to limit the scope of the invention. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of the present invention should fall within the scope of protection of the present invention.
