Abstract

This application relates to a rapid roof cooling component, a sunroof assembly, and an automobile. The rapid roof cooling component includes a drainage pipe and an air blowing pipe. At least one drainage pipe is connected to the air outlet of an air conditioning unit. The air blowing pipe is connected to the drainage pipe and is located inside the vehicle body and positioned on the roof. The air blowing pipe has air blowing holes that face the sunroof glass. In operation, the rapid roof cooling component draws cold air from the air conditioning unit's outlet into the drainage pipe, which then delivers it to the air blowing pipe. Because the air blowing pipe is located on the roof, and its air blowing holes face the sunroof glass, the cold air from the air conditioning unit is guided and blown towards the sunroof glass, achieving rapid cooling of the sunroof glass without altering the product's appearance.

Description

Technical Field

[0001] This invention relates to the field of vehicle roof cooling technology, and in particular to a vehicle roof rapid cooling component, sunroof assembly, and automobile. Background Technology

[0002] Panoramic sunroofs are mainly divided into variable (openable) panoramic sunroofs and fixed panoramic sunroofs. Fixed panoramic sunroofs are currently the most frequently used sunroof design in vehicles. Their glass is fixed to the vehicle body using an adhesive process and cannot be opened. Fixed panoramic sunroofs have a larger opening, allowing for a larger area of ​​direct sunlight. Some models have a sunshade installed below the sunroof for heat insulation; while other models only have a single glass sunroof, which has poor heat insulation and can make the roof feel hot.

[0003] There are two main solutions on the market for the overheating problem of panoramic sunroofs:

[0004] (1) Ordinary window film

[0005] PET functional films applied to automotive glass offer various benefits, including heat insulation, UV protection, glare reduction, decoration, privacy protection, and explosion-proof safety. However, while window tinting can alleviate overheating issues to some extent, it also has negative impacts. Firstly, the market offers a wide variety of films at high prices, making it difficult for consumers to choose. Secondly, the films often have poor weather resistance, leading to issues like bubbling and peeling. Finally, tinting significantly increases the risk of spontaneous glass breakage. Due to the difference in thermal expansion coefficients between the film and the glass, uneven heating after sun exposure disrupts the internal tensile and compressive stress distribution, potentially causing spontaneous breakage. Statistics show that tinting can increase the spontaneous breakage rate by one-thousandth. Therefore, while window tinting addresses sunroof overheating, it also introduces several negative consequences.

[0006] (2) Application of deep privacy gray glass

[0007] Some car sunroofs use dark privacy gray glass, which offers about a 6% improvement in heat insulation compared to regular glass. While dark privacy gray glass provides a significant improvement in heat insulation compared to regular glass, it also avoids the risk of spontaneous breakage associated with regular gray glass film. However, due to its darker tint and lower light transmittance, the interior of the car can feel more oppressive and stuffy. Summary of the Invention

[0008] Therefore, it is necessary to overcome the shortcomings of existing technologies and provide a roof rapid cooling component, sunroof assembly and automobile that can achieve rapid roof cooling without changing the product appearance.

[0009] The technical solution is as follows: A vehicle roof rapid cooling component, the vehicle roof rapid cooling component comprising:

[0010] A drainage pipe, at least one of the drainage pipes being connected to the air outlet of an air conditioning unit;

[0011] An air blowing pipe is provided, which is connected to the drainage pipe. The air blowing pipe is installed inside the vehicle body and arranged on the roof. The air blowing pipe is provided with an air blowing hole, which is used to face the sunroof glass of the roof.

[0012] In one embodiment, the air blowing pipe is fixedly connected to the sunroof glass, and the air blowing pipe is arranged along the edge of the sunroof glass.

[0013] In one embodiment, there are two air blowing pipes, which are respectively arranged on opposite sides of the sunroof glass.

[0015] In one embodiment, a plurality of the air holes are arranged at equal intervals on the air blowing pipe.

[0016] In one embodiment, the air inlet is a waist-shaped inlet with a length of 15mm to 100mm and a width of 2mm to 5mm.

[0017] In one embodiment, the angle between the air outlet direction and the surface of the sunroof glass is 2° to 10°.

[0018] In one embodiment, at least one axial flow fan is provided inside the drainage pipe.

[0019] In one embodiment, there are multiple axial flow fans; the multiple axial flow fans are arranged sequentially along the axial direction of the drainage pipe, and / or arranged side by side at the same part of the drainage pipe.

[0020] In one embodiment, the inner wall of the drainage pipe is connected to a support member, which is connected to the motor of the axial flow fan. The support member includes a plurality of support blocks arranged circumferentially around the motor at intervals.

[0021] In one embodiment, the drainage pipe is used to pass through at least one of the A-pillar, B-pillar, C-pillar, and D-pillar of the vehicle body.

[0022] In one embodiment, the top of the drainage pipe extends out from the B-pillar and connects to the middle part of the air blowing pipe; or, the air blowing pipe includes a first air blowing pipe and a second air blowing pipe, and the top of the drainage pipe is provided with a first arc-shaped air outlet and a second arc-shaped air outlet, the first arc-shaped air outlet being connected to the first air blowing pipe, and the second arc-shaped air outlet being connected to the second air blowing pipe.

[0023] In one embodiment, the roof rapid cooling assembly further includes a variable diameter connecting pipe corresponding to the drainage pipe and the air blowing pipe. The drainage pipe is connected to the air blowing pipe through the variable diameter connecting pipe. The inner diameter of the drainage pipe is larger than that of the air blowing pipe. The variable diameter connecting pipe includes a pipe section whose inner diameter decreases along the airflow direction.

[0024] In one embodiment, the roof rapid cooling assembly further includes an exhaust pipe for connection to the air intake of the air conditioning unit.

The air outlet of the air conditioning unit is connected to the air diversion pipe, the air blowing pipe is connected to the roof, and the air blowing hole faces the sunroof glass.

[0028] When the aforementioned rapid cooling roof assembly, sunroof assembly, and automobile are in operation, the cold air exhausted from the air conditioning unit's outlet enters the drainage pipe and is then transported to the air blowing pipe. Since the air blowing pipe is located on the roof, the air blowing holes of the air blowing pipe face the sunroof glass, guiding the cold air from the air conditioning unit and blowing it towards the sunroof glass, thereby achieving rapid cooling of the sunroof glass without altering the product's appearance.

[0043] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0044] See Figures 1 to 5 , Figure 1 This paper shows a top view of a vehicle roof rapid cooling assembly according to an embodiment of the present application. Figure 2 It shows Figure 1 Schematic diagram of the cross-sectional structure at point AA Figure 3 It shows Figure 1 Cross-sectional structural diagram at BB. Figure 4 This illustration shows a schematic diagram of the air blowing pipe 20 connected to the sunroof glass 411 according to an embodiment of this application. Figure 5 It shows Figure 4 A cross-sectional view at CC. One embodiment of this application provides a rapid roof cooling assembly, comprising: a drainage pipe 10 and an air blowing pipe 20. At least one drainage pipe 10 is connected to the air outlet 30 of an air conditioning unit. The air blowing pipe 20 is connected to the drainage pipe 10 and is disposed inside the vehicle body 40 and arranged on the roof 41. The air blowing pipe 20 has an air blowing hole 21, which is directed towards the sunroof glass 411 of the roof 41.

[0045] When the aforementioned rapid cooling roof component is in operation, the cold air discharged from the air outlet 30 of the air conditioning unit enters the diversion pipe 10 and is delivered to the air blowing pipe 20 through the diversion pipe 10. Since the air blowing pipe 20 is located on the roof 41, the air blowing hole 21 of the air blowing pipe 20 faces the sunroof glass 411 of the roof 41, guiding the cold air from the air conditioning unit and blowing it towards the sunroof glass 411, which can achieve rapid cooling of the sunroof glass 411 of the roof 41 without changing the appearance of the product.

[0046] It should be noted that the air blowing pipe 20 can be arranged in various ways on the roof 41, such as along the edge of the sunroof glass 411, near the black rubber ring around the glass, or in other ways. When the sunroof glass 411 is a square window, the air blowing pipe 20 can be located on at least one side of the sunroof glass 411, including but not limited to the left, right, front, and rear sides. Furthermore, the air blowing pipe 20 can also be parallel to or at an angle to the side of the sunroof glass 411, as long as the cold airflow inside the air blowing pipe 20 can be blown towards the sunroof glass 411 through the air blowing hole 21. The specific arrangement can be flexibly adjusted and set according to actual needs.

[0047] Please see Figure 1 In one embodiment, the air blowing pipe 20 is fixedly connected to the sunroof glass 411. Optionally, the air blowing pipe 20 is arranged along the edge of the sunroof glass 411. In this way, the distance between the air blowing pipe 20 and the edge of the sunroof glass 411 is relatively small, and the cold airflow blowing onto the sunroof glass 411 of the roof 41 has a better cooling effect.

[0048] Please see Figure 1 In one embodiment, there are two air blowing pipes 20, which are respectively arranged on opposite sides of the sunroof glass 411. Specifically, the two air blowing pipes 20 are located on the side of the sunroof glass 411 closer to the left door and the side closer to the right door, respectively. In this way, by blowing cold air from one side of the sunroof glass 411 through one air blowing pipe 20 and blowing cold air from the opposite side of the sunroof glass 411 through the other air blowing pipe 20, rapid cooling of the sunroof glass 411 can be achieved.

[0049] Accordingly, there are two drainage pipes 10, which are respectively connected to two air blowing pipes 20. In addition, the two drainage pipes 10 are connected to the same air outlet 30 of the air conditioning unit, for example. In this way, the cold air discharged from the air outlet 30 of the air conditioning unit enters the two drainage pipes 10 respectively, and then enters the first air blowing pipe 23 and the second air blowing pipe 24 respectively through the two drainage pipes 10.

[0050] In one embodiment, when there are at least two air blowing ducts 20, such as three, four, five, or other numbers, there are correspondingly at least two drainage ducts 10, which are arranged accordingly with the air blowing ducts 20. In this way, at least two drainage ducts 10 respectively deliver the cold air from the air conditioning unit to at least two air blowing ducts 20. In addition, the air outlet 30 of the air conditioning unit can be one, which is connected to at least two drainage ducts 10 respectively, that is, one air outlet 30 provides cold air to at least two drainage ducts 10 respectively; or it can be set to at least two, which are respectively arranged with at least two drainage ducts 10 respectively, that is, at least two air outlets 30 respectively provide cold air to at least two drainage ducts 10 respectively. In this way, the air outlets 30 and the air blowing ducts 20 can be connected through the drainage ducts 10 according to the principle of proximity, which simplifies the duct layout structure.

[0051] Please see Figure 4 and Figure 5 In one embodiment, the air blowing pipe 20 is fixed to the roof 41 by means of fasteners such as adhesive material 22, snap fasteners, screws, rivets, pins, connecting ropes, etc. It can also be integrally injection molded to the roof 41 by injection molding material. The injection molding material can be fully wrapped (circumferentially surrounding the air blowing pipe 20) or partially wrapped (covering a part of the outer wall of the air blowing pipe 20) and connected to the air blowing pipe 20.

[0052] Optionally, the cross-section of the air blowing pipe 20 may include, but is not limited to, regular shapes such as circles, ellipses, polygons, and irregular shapes, which can be flexibly adjusted and set according to actual needs.

[0053] In one embodiment, the air blowing pipe 20 has multiple air blowing holes 21, which are arranged at intervals along the length of the air blowing pipe 20. In this way, the multiple air blowing holes 21 of the air blowing pipe 20 simultaneously blow cold air to multiple different positions on the surface of the sunroof glass 411, so that all parts of the surface of the sunroof glass 411 have a good cooling effect.

[0054] In one embodiment, a plurality of air holes 21 are arranged at equal intervals on the air pipe 20.

[0055] Specifically, the interval between two adjacent air holes 21 is, for example, 100mm to 150mm.

[0056] Please see Figure 4 and Figure 5In one embodiment, the air inlet 21 is an oblong hole with a length of 15mm to 100mm and a width of 2mm to 5mm. Thus, when the air inlet 21 arranged on the inner wall of the air pipe is specifically set as an oblong hole, compared with other shapes of air inlets 21 with the same cross-sectional area, the oblong hole has a smaller dimension in the width direction, which is easier for the overall vehicle design.

[0057] Of course, as some optional solutions, the shape of the air hole 21 is not limited to an oblong shape. It can also be designed as a regular shape such as a circular hole or a polygonal hole, as well as an irregular shape, depending on actual needs.

[0058] Please see Figure 5 In some embodiments, the angle formed between the air outlet 21 and the surface of the sunroof glass 411 is an acute angle, thereby enabling the cold airflow to be blown directly onto the sunroof glass 411.

[0059] In one embodiment, the angle between the air outlet 21 and the surface of the sunroof glass 411 is 2° to 10°. Thus, setting the angle between 2° and 10° allows for a larger area of ​​cold airflow covering the surface of the sunroof glass 411, resulting in a larger cooling area and a better cooling effect.

[0060] Of course, as some optional solutions, the angle formed between the air outlet direction of the air vent 21 and the surface of the sunroof glass 411 can be any value other than 2° to 10°, and can be flexibly adjusted and set according to actual needs.

[0061] Optionally, the materials of the air blowing pipe 20 and the drainage pipe 10 may include, but are not limited to, PU, ​​PVC, PP+glass fiber, ABS, PP, PPMA, and rubber.

[0062] Please see Figure 3 and Figure 6 , Figure 6 A schematic diagram of an axial flow fan 50 connected inside a drainage pipe 10 according to an embodiment of this application is shown. In one embodiment, at least one axial flow fan 50 is disposed inside the drainage pipe 10. The axial flow fan 50 can be either a direct-flow axial flow fan 50 or an alternating-flow axial flow fan 50, and can be flexibly configured according to actual needs. In addition, a small-sized axial flow fan 50 is selected so that it can be installed in the drainage pipe 10. When the axial flow fan 50 is working, it can provide power to draw the cold air from inside the drainage pipe 10 outward. The cold air is blown towards the surface of the sunroof glass 411 at a greater speed, resulting in a larger coverage area on the surface of the sunroof glass 411 and a better cooling effect.

[0063] In one embodiment, the drainage pipe 10 is, for example, a circular surface with a diameter including but not limited to 20mm to 100mm, or a cross-section of other regular or irregular shapes with the same area as the circular surface.

[0064] Please see Figure 3 and Figure 6 In one embodiment, multiple axial flow fans 50 are used. Thus, when multiple axial flow fans 50 operate synchronously, the air pressure is increased, resulting in a larger coverage area on the surface of the skylight glass 411 and a better cooling effect. Optionally, the multiple axial flow fans 50 are arranged sequentially along the axial direction of the drainage duct 10 (e.g., Figure 3 (As shown). Furthermore, the drainage duct 10 is, for example, a circular duct, and corresponds to the body shape of the axial flow fan 50. Optionally, multiple axial flow fans 50 may be arranged side-by-side at the same location within the drainage duct 10. Optionally, a plurality of axial flow fans 50 may be arranged sequentially along the axial direction of the drainage duct 10, while another plurality of axial flow fans 50 may be arranged side-by-side at the same location within the drainage duct 10.

[0065] Please see Figure 6 and Figure 7 , Figure 6 This paper shows a schematic diagram of an axial flow fan 50 connected inside a diversion pipe 10 according to an embodiment of this application. Figure 7 It shows Figure 6 A cross-sectional view at DD. In one embodiment, a support member 60 is connected to the inner wall of the drainage pipe 10. The support member 60 is connected to the motor 51 of the axial flow fan 50. The support member 60 includes a plurality of support blocks 61 arranged circumferentially around the motor 51 at intervals. Thus, the support member 60 allows the axial flow fan 50 to be stably installed inside the drainage pipe 10, driving the fan blades 52 through the motor 51 to accelerate the gas flow within the pipe. Furthermore, the cold airflow passes through the intervals between adjacent support blocks 61. Specifically, the support blocks 61 are divided into six or more or fewer, and the cross-sectional area of ​​the support blocks 61 is minimized to reduce gas transmission loss within the pipe.

[0066] Please see Figure 6 and Figure 7Specifically, the support member 60 also includes an inner ring connecting plate 62 and an outer ring connecting plate 63. One end of a plurality of support blocks 61 is connected to the inner ring connecting plate 62, and the motor 51 passes through and is connected to the inner ring connecting plate 62. The other end of the plurality of support blocks 61 is connected to the outer ring connecting plate 63, which is connected to the inner wall of the drainage channel. Thus, on the one hand, since the outer ring connecting plate 63 is connected to the inner wall of the drainage pipe 10, the support member 60 can be stably installed on the inner wall of the drainage pipe 10, and the connection methods include, but are not limited to, bonding, snap-fitting, and fixing with fasteners such as screws, pins, and rivets; on the other hand, since the inner ring connecting plate 62 is connected to the outer wall of the motor 51, the motor 51 can be stably installed on the support member 60, and the connection methods include, but are not limited to, bonding, snap-fitting, and fixing with fasteners such as screws, pins, and rivets.

[0067] It should be noted that the "inner ring connecting plate 62 and outer ring connecting plate 63" can be "part of the support block 61", that is, the "inner ring connecting plate 62 and outer ring connecting plate 63" are integrally formed with the "other parts of the support block 61"; or they can be separate components from the "other parts of the support block 61", that is, the "inner ring connecting plate 62 and outer ring connecting plate 63" can be manufactured independently and then combined with the "other parts of the support block 61" to form a whole. Figure 7 As shown, in one embodiment, the "inner ring connecting plate 62 and outer ring connecting plate 63" are integrally formed as part of the "support block 61".

[0068] Please see Figure 2 and Figure 3 as well as Figure 11 , Figure 11 A schematic diagram of a roof rapid cooling assembly according to another embodiment of this application is shown. In one embodiment, the drainage pipe 10 is used to pass through the A-pillar 42 of the vehicle body 40 (e.g., Figure 11 As shown), B-pillar 43 (as shown) Figure 2 or Figure 3 (as shown), at least one of the C-pillar and D-pillar. In this way, the drainage pipe 10 extends from the bottom of the vehicle body 40 upwards along the A-pillar 42, B-pillar 43, C-pillar, and D-pillar to the top of the vehicle body 40. The concealed arrangement can prevent the drainage pipe 10 from being exposed.

[0069] Please see Figures 1 to 3 as well as Figure 8 , Figure 8A schematic diagram of the structure of the drainage pipe 10 and the air blowing pipe 20 connected according to an embodiment of this application is shown. In this embodiment, the drainage pipe 10 is specifically installed in the B-pillar 43. The internal space volume of the B-pillar 43 of the car is larger than that of other locations, making it easier to arrange the pipe. In addition, the B-pillar 43 is located in the middle of the car body 40. After the drainage pipe 10 is led upward through the internal space of the B-pillar 43, it is connected to the middle part of the air blowing pipe 20. On the one hand, the travel distance at the B-pillar 43 is the shortest. On the other hand, when the air blowing pipe 20 acts on the surface of the sunroof glass 411, it has a more uniform cooling effect.

[0070] Please see Figure 9 , Figure 9 A schematic diagram of the structure of the drainage pipe 10 connected to the air blowing pipe 20 according to another embodiment of this application is shown. In one embodiment, the air blowing pipe 20 includes a first air blowing pipe 23 and a second air blowing pipe 24. The top of the drainage pipe 10 is provided with a first arc-shaped air outlet 11 and a second arc-shaped air outlet 12. The first arc-shaped air outlet 11 is connected to the first air blowing pipe 23, and the second arc-shaped air outlet 12 is connected to the second air blowing pipe 24. In this way, the cold airflow inside the drainage pipe 10 is discharged into the first air blowing pipe 23 through the first arc-shaped air outlet 11, and then discharged outward to the sunroof glass 411 through the first air blowing pipe 23. It is also discharged into the second air blowing pipe 24 through the second arc-shaped air outlet 12, and then discharged outward to the sunroof glass 411 through the second air blowing pipe 24. That is, the diversion structure at the top of the drainage pipe 10 is in the shape of an inverted "V", which can reduce the pressure loss of gas flow.

[0071] Please see Figure 10 , Figure 10 A schematic diagram of a drainage pipe 10 connected to an air blowing pipe 20 via a reducing pipe 70, according to an embodiment of this application, is shown. In one embodiment, the roof rapid cooling assembly further includes a reducing pipe 70 correspondingly connected between the drainage pipe 10 and the air blowing pipe 20. The drainage pipe 10 is connected to the air blowing pipe 20 via the reducing pipe 70. The inner diameter of the drainage pipe 10 is larger than that of the air blowing pipe 20, and the reducing pipe 70 includes a section whose inner diameter decreases along the airflow direction. Thus, the gas inside the drainage pipe 10 is pressurized as it is introduced into the air blowing pipe 20 through the reducing pipe 70.

[0072] In one embodiment, the inner diameter of the reducing connector 70 can decrease from one end to the other, meaning the entire inner diameter of the reducing connector 70 is designed to gradually decrease. Alternatively, for example, the inner diameter of the first half can gradually decrease, while the inner diameter of the second half is constant. Another option is that the inner diameter of the second half decreases while the inner diameter of the first half gradually decreases. Yet another option is that the inner diameter at both ends remains constant, while the inner diameter in the middle section decreases. A third option is to alternate between sections with constant inner diameters and sections with gradually decreasing inner diameters. Of course, it can also include sections with gradually increasing inner diameters. The specific arrangement is not limited here and can be flexibly adjusted and designed according to actual needs, as long as it can pressurize the flowing air.

[0073] In one embodiment, the roof rapid cooling assembly also includes an exhaust pipe (not shown). The exhaust pipe is used to connect to the air intake of the air conditioning unit. Specifically, one end of the exhaust pipe is located on the roof 41, and the other end is connected to the air intake of the air conditioning unit, i.e., connected to the air conditioning compressor. Thus, when the air compressor is working, it generates suction at the air intake, causing hot air near the roof 41 to enter the air conditioning unit through the exhaust pipe, thereby utilizing the air conditioning ventilation function to promptly expel the hot air from the roof 41. Normally, automotive air conditioning cools the entire vehicle starting from the air vents, with the roof 41 cooling the slowest. This ventilation system can directly draw away the hot air from the roof 41, achieving rapid cooling of the roof.

[0074] In one embodiment, part of the drainage pipe 10 is connected to the air outlet 30 of the air conditioning unit, and another part of the drainage pipe 10 is connected to the air inlet of the air conditioning unit. Thus, on the one hand, the cold air inside part of the drainage pipe 10 enters the air blowing pipe 20 and is discharged outwards to the sunroof glass 411 through the air blowing pipe 20; on the other hand, under the suction force of the air inlet of the air conditioning unit, hot air near the roof 41 can sequentially enter the air conditioning unit through the air blowing pipe 20 and the other part of the drainage pipe 10, thereby utilizing the air conditioning ventilation function to promptly expel the hot air from the roof 41.

[0075] Please see Figures 1 to 5 In one embodiment, a sunroof assembly includes a roof rapid cooling component of any of the above embodiments, and also includes a sunroof glass 411, with an air blowing pipe 20 fixedly connected to the sunroof glass 411 and an air blowing hole 21 facing the sunroof glass 411.

[0076] When the sunroof assembly described above is in operation, since the air blowing pipe 20 is located on the sunroof glass 411 and the air blowing hole 21 of the air blowing pipe 20 is facing the sunroof glass 411, the cold air from the air conditioning unit is guided and blown toward the sunroof glass 411, which can achieve rapid cooling of the sunroof glass 411 on the roof 41 without changing the appearance of the product.

[0077] In one embodiment, the air blowing pipe 20 is fixed to the sunroof glass 411 by means of fasteners such as adhesive material 22, snap fasteners, screws, rivets, pins, connecting ropes, etc., or it can be integrally injection molded to the sunroof glass 411 by means of injection molding material. The injection molding material can be fully wrapped (circumferentially surrounding the air blowing pipe 20) or partially wrapped (covering a part of the outer wall of the air blowing pipe 20) and connected to the air blowing pipe 20.

[0078] Please see Figures 1 to 5 In one embodiment, an automobile includes the roof rapid cooling assembly of any of the above embodiments, and also includes a body 40, an air conditioning unit disposed on the body 40, and a sunroof glass 411 disposed on the roof 41. The air outlet 30 of the air conditioning unit is connected to the drainage pipe 10, the air blowing pipe 20 is connected to the roof 41, and the air blowing hole 21 faces the sunroof glass 411.

[0079] In the aforementioned vehicle, when in operation, the cold air discharged from the air outlet 30 of the air conditioning unit enters the diversion duct 10 and is delivered to the air blowing duct 20 through the diversion duct 10. Since the air blowing duct 20 is located on the roof 41, the air blowing hole 21 of the air blowing duct 20 faces the sunroof glass 411 of the roof 41, guiding the cold airflow of the air conditioning unit and blowing it towards the sunroof glass 411, which can achieve rapid cooling of the sunroof glass 411 of the roof 41 without changing the appearance of the product.

[0080] The technical features of the above embodiments can be combined in any way.
