[0044] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0045] The following is for reference. Figures 1-18 A sunroof thermal insulation assembly 10 according to a first aspect of the present invention is described.

[0046] like Figure 12 As shown, the sunroof heat insulation assembly 10 according to the first aspect embodiment of the present invention is provided on the side of the sunroof glass 20 facing the vehicle interior, and includes: an air pipe 2, the air pipe 2 extending circumferentially along the sunroof glass 20, and the air pipe 2 having a plurality of ventilation holes 23 arranged at intervals along the circumferential direction of the sunroof glass 20, the plurality of ventilation holes 23 being disposed facing the central region of the sunroof glass 20.

[0047] The sunroof 20 is located on the top of the vehicle 100 and is generally rectangular. The air duct 2 extends circumferentially along the sunroof 20 and is arranged around the edge of the sunroof 20. Multiple ventilation holes 23 are arranged at intervals on the air duct 2. For example, there can be two, three or more ventilation holes 23. The multiple ventilation holes 23 are arranged opposite each other so that the gas is blown toward the central area of ​​the sunroof 20. This creates a flowing airflow layer on the side of the sunroof 20 facing the inside of the vehicle, which carries away the heat at the location of the sunroof 20 and reduces the temperature of the sunroof 20 area. At the same time, it can also block the vertical radiation of heat to the occupants of the vehicle, thereby producing a heat insulation effect. This improves the heat problem at the top of the occupants' heads, reduces the large temperature gradient between the roof area and other areas of the vehicle, and increases the comfort of the occupants. In addition, the airflow at the sunroof glass 20 will cause a large temperature difference between the inner and outer surfaces of the sunroof glass 20. As a result, water vapor will form near the surface of the sunroof glass 20, which will then form a layer of water mist. This can achieve a partial shading effect while also providing heat insulation, thereby improving the comfort of passengers.

[0048] During hot summer weather, the air duct 2 supplies cool air to the vehicle interior through the ventilation holes 23. This cool air is blown from multiple ventilation holes 23 towards the central area of ​​the sunroof glass 20, creating a flowing airflow layer on the lower surface of the sunroof glass 20. This quickly lowers the temperature of the sunroof glass 20 area and provides insulation, thus reducing the temperature above the passengers' heads and minimizing head heat. Simultaneously, a significant temperature difference is created between the inner and outer surfaces of the sunroof glass 20, causing condensation to form on its surface. This creates a layer of mist, providing both insulation and partial sunshade, further reducing head heat. During cold winter driving, the air duct 2 supplies warm air to the vehicle interior through the ventilation holes 23. Warm air is blown towards the roof of the vehicle 100 through multiple ventilation holes 23, raising the temperature of the sunroof glass 20 area. This also raises the temperature above the passengers' heads, reducing the temperature difference between the roof area and other areas of the vehicle interior, increasing passenger comfort.

[0049] According to an embodiment of the present invention, the sunroof heat insulation assembly 10, by providing a plurality of ventilation holes 23 arranged circumferentially along the sunroof glass 20 on the air pipe 2, can blow air into the central area of ​​the sunroof glass 20 from multiple directions. This can form a flowing airflow layer on the side surface of the sunroof glass 20 facing the vehicle interior, which can carry away the heat at the sunroof glass 20 location through the airflow, thereby improving the temperature of the sunroof glass 10 area. At the same time, it can also block heat from vertically radiating to the occupants of the vehicle, thereby producing a heat insulation effect and improving the heat problem of the head area of ​​the passengers. In addition, it can also reduce the temperature difference between the roof area and other areas of the vehicle interior, increasing the passenger comfort.

[0050] According to some embodiments of the present invention, the inlet end of the air pipe 2 is connected to the air conditioning system of the vehicle 100. The air conditioning system of the vehicle 100 provides an air source for the air pipe 2. The air outlet mode of the air pipe 2 can be controlled by controlling the air conditioning system of the vehicle 100, thereby reducing the use of a control system, thus lowering production costs and saving installation space.

[0051] According to some embodiments of the present invention, such as Figure 1 As shown, the sunroof insulation assembly 10 also includes an air inlet pipe 3 and a first air pump 1. The outlet end of the air inlet pipe 3 is connected to the air pipe 2, and the first air pump 1 is connected in series with the air inlet pipe 3. The outlet end of the air inlet pipe 3 is connected to the air pipe 2, and the other end is connected to the air conditioning outlet. The first air pump 1 is connected in series with the air inlet pipe 3 and is located between the air conditioning outlet and the air inlet of the air pipe 2. The first air pump 1 is mainly used to pressurize the air conditioning air entering the air inlet pipe 3, so that the gas entering the air pipe 2 has a certain pressure, and thus the gas can be sprayed from the ventilation hole 23 to the center of the sunroof glass 20.

[0052] Furthermore, the first air pump 1 can be a gas compression pump, which can change the degree of gas pressurization by rotating the speed. For example, when the gas compression pump is set to a high speed, the gas processed by the first air pump 1 is high-pressure gas; when the speed of the first compression pump is set to a low speed, the gas processed by the first air pump 1 is low-pressure gas.

[0053] Optionally, the first air pump 1 can be mounted on the body sheet metal to improve the installation stability of the first air pump 1.

[0054] According to some embodiments of the present invention, such as Figure 1 As shown, the sunroof insulation assembly 10 also includes a first air tank 4, which is connected in series with the air inlet pipe 3 and located downstream of the first air pump 1 in the airflow direction. The airflow direction is from the air conditioning outlet to the air inlet of the air pipe 2. That is, the first air tank 4 is positioned between the first air pump 1 and the air inlet of the air pipe 2, primarily used to store the gas processed by the first air pump 1 and simultaneously supply processed airflow to the air pipe 2. This ensures smooth air supply, improves the stability of gas output in the air pipe 2, and thus enhances passenger comfort. Furthermore, the size of the first air tank 4 can be designed and manufactured according to actual requirements.

[0055] According to some embodiments of the present invention, such as Figure 1 As shown, the sunroof heat insulation assembly 10 also includes an air purifier 91, which is connected in series with the air intake duct 3 and can be used to purify the gas entering the air duct 2, thereby effectively improving the cleanliness of the gas entering the sunroof glass 20 area and thus improving the comfort of the passengers.

[0056] According to some embodiments of the present invention, such as Figures 1-4 As shown, the multiple ventilation holes 23 include first air holes 231, and the air duct 2 includes a first air duct 21. The first air duct 21 extends circumferentially along the sunroof glass 20, and the first air duct 21 is provided with multiple first air holes 231. At least some of the positions of the first air holes 231 are provided with high-pressure nozzles. That is to say, all of the first air holes 231 can be provided with high-pressure nozzles, or some can be provided with high-pressure nozzles and some can be low-pressure air holes. When all of the first air holes 231 are provided with high-pressure nozzles, the first air duct 21 acts as a high-pressure air duct, providing high-pressure airflow to the vehicle interior, which can quickly reduce the temperature of the top of the vehicle 100, forming laminar flow, thereby quickly reducing the temperature of the sunroof area and providing heat insulation, shortening the cooling time, and increasing the comfort of passengers. When some of the first air holes 231 are provided with high-pressure nozzles, the first air duct 21 can act as both a high-pressure air duct and a low-pressure air duct, thus achieving multiple uses for one duct, thereby reducing the number of parts used and reducing production costs.

[0057] Optionally, when the first air duct 21 can be used as both a high-pressure air duct and a low-pressure air duct, the blowing mode can be manually switched. That is, when other first air holes 231 are closed and the high-pressure nozzle is opened, the high-pressure blowing mode is entered; when other first air holes 231 are opened and the high-pressure nozzle is closed, the low-pressure blowing mode is entered.

[0058] According to some embodiments of the present invention, such as Figures 1-4 As shown, the multiple ventilation holes 23 include second air holes 232, and the air duct 2 includes a second air duct 22. The second air duct 22 is arranged circumferentially along the sunroof glass 20 and is arranged side by side with the first air duct 21. The second air duct 22 is provided with multiple second air holes 232. For example, the number of second air holes can be two, three or more. The multiple second air holes 232 can realize multi-directional airflow to the area of ​​the sunroof glass 20, thereby increasing the heat insulation and heat dissipation effect of the sunroof glass 20 area.

[0059] According to some embodiments of the present invention, such as Figure 1 As shown, the first air vent 231 and the second air vent 232 are staggered around the sunroof glass 20, which can improve the heat insulation effect of the sunroof glass 20 area and increase the airflow comfort of the passengers' heads.

[0060] According to some embodiments of the present invention, such as Figure 1As shown, the sunroof insulation assembly 10 also includes an exhaust duct 7 and a second air pump 6. The exhaust duct 7 is connected to the second duct 22, and the second air pump 6 is connected in series with the exhaust duct 7. One end of the exhaust duct 7 is connected to the second duct 22, and the other end is connected to the outside. The second air pump 6, connected in series with the exhaust duct 7, is mainly used to exhaust air from inside the vehicle to the outside, thereby purifying the air inside the vehicle and improving air circulation. Additionally, the second air pump 6 can be activated simultaneously with high-pressure air blowing from the first duct 21 to increase airflow over the top of the vehicle 100, thereby increasing heat dissipation and improving passenger comfort.

[0061] Furthermore, the second air pump 6 can be a suction pump to provide power for exhausting air from inside the vehicle; the second air pump 6 is installed on the body sheet metal, which can increase the installation stability of the second air pump 6.

[0062] According to some embodiments of the present invention, such as Figure 16 As shown, the sunroof insulation assembly 10 also includes a control valve 93, which is connected to the air inlet pipe 3, the first air duct 21, the second air duct 22, and the exhaust pipe 7. The control valve 93 controls the direction and flow rate of the airflow, thereby enabling switching between different modes and settings, improving control convenience and passenger comfort. Furthermore, the control valve 93 can be of various types, such as a solenoid valve or an electric valve.

[0063] According to some embodiments of the present invention, such as Figure 1 As shown, the sunroof insulation assembly 10 also includes a second air tank 5, which is connected in series with the exhaust duct 7 and located upstream of the second air pump 6 in the airflow direction. The airflow direction is from the second duct 22 to the exhaust port of the exhaust duct 7. The second air duct 22 is positioned upstream of the second air pump 6 in the airflow direction, that is, between the air inlet of the exhaust duct 7 and the second air pump 6. The second air tank 5 is mainly used to store the gas entering the second air tank 5 from the second duct 22, ensuring smooth exhaust and thus improving the operational stability of the second air pump 6.

[0064] Optionally, the sunroof insulation assembly 10 also includes an air filter 92, which is connected in series with the exhaust pipe 7 and located downstream of the second air pump 6 in the airflow direction. The air filter 92 is mainly used to filter the exhaust gas from the vehicle to ensure that the exhaust gas meets emission standards. It also prevents impurities from entering the second air pump 6 through the exhaust pipe 7, thereby improving the safety of the second air pump 6.

[0065] According to some embodiments of the present invention, such as Figure 1 and Figure 12As shown, the sunroof insulation assembly 10 also includes: a mounting bracket 8, which extends circumferentially along the sunroof glass 20, and the inner side of the mounting bracket 8 defines an installation space extending circumferentially along the sunroof glass 20, with the air pipe 2 disposed within the installation space.

[0066] The mounting bracket 8 provides installation space for the air pipe 2, high-pressure nozzle 24 and other components, which can integrate the air pipe 2, high-pressure nozzle 24 and other components into one unit, thereby increasing the integration and aesthetics of the sunroof heat insulation assembly 10, reducing the installation space of the sunroof heat insulation assembly 10, and increasing the overall aesthetics of the vehicle 100.

[0067] Furthermore, for example Figure 12 As shown, the mounting bracket 8 includes a first mounting section and a second mounting section, which are connected to each other. The first mounting section is annular, extending along the periphery of the sunroof glass 20, and both the air pipe 2 and the high-pressure nozzle 24 are installed within it. The second mounting section is connected to one side of the first mounting section along its length and is located at the center of the first mounting section along its width. The second mounting section is used to install the control valve 93 and its associated piping. The first air tank 4 and the second air tank 5 are respectively installed on the left and right sides of the second mounting section.

[0068] In some specific embodiments of the present invention, the sunroof thermal insulation assembly 10 further includes an electronic control system, which is electrically connected to the first air pump 1, the second air pump 6, and the control valve 93. The first air pump 1, the second air pump 6, and the control valve 93 are respectively connected to the electronic control system via wiring harnesses. The electronic control system can switch the functional modes of the sunroof thermal insulation assembly 10 by controlling the opening and speed changes of the first air pump 1 and the second air pump 6, and by controlling the opening and switching of the control valve 93, thereby improving the automation of the sunroof thermal insulation assembly 10.

[0069] A vehicle 100 according to a second aspect of the present invention includes a sunroof glass 20 and a sunroof heat insulation assembly 10 according to a first aspect of the present invention.

[0070] Furthermore, the sunroof glass 20 has multiple mounting seats 201 on the side facing the vehicle interior. These mounting seats 201 are spaced apart circumferentially along the sunroof glass 20. The mounting bracket 8 is connected to the mounting seats 201 to securely connect the sunroof insulation assembly 10 to the sunroof glass 20. The mounting bracket 8 and mounting seats 201 can be connected using fasteners, such as bolts, for easy installation, disassembly, and maintenance.

[0071] Optionally, the sunroof glass 20 can be gray glass or photochromic glass.

[0072] According to an embodiment of the present invention, the overall performance of the vehicle 100 is improved by providing the sunroof heat insulation assembly 10 of the first aspect embodiment described above.

[0073] The following will refer to Figures 1-18 A vehicle 100 according to an embodiment of the present invention is described.

[0074] Reference Figure 1 The vehicle 100 includes a sunroof glass 20 and a sunroof heat insulation assembly 10, wherein the sunroof heat insulation assembly 10 is fixed to the sunroof glass 20, and the sunroof glass 20 may be gray glass or photochromic glass.

[0075] like Figure 4 and Figure 12 As shown, the sunroof insulation assembly 10 includes a first air pump 1, an air pipe 2, an air inlet pipe 3, a first air tank 4, a second air tank 5, a second air pump 6, an exhaust pipe 7, a mounting bracket 8, a control valve 93, an electrical control system, an air purifier 91, and an air filter 92. The electrical control system is electrically connected to the first air pump 1, the second air pump 6, and the control valve 93. The mounting bracket 8 extends circumferentially along the sunroof glass 20. The mounting bracket 8 is a rectangular frame, and its inner side defines an installation space extending circumferentially along the sunroof glass 20. The air pipe 2 is located within this installation space.

[0076] The inlet end of the air pipe 2 is connected to the air conditioning system of the vehicle 100 via the air intake pipe 3. The first air pump 1 is located between the air conditioning system and the inlet end of the air pipe 2, and is used to pump gas into the air pipe 2. A first air tank 4 is also connected in series on the air intake pipe 3. The first air tank 4 is located between the first air pump 1 and the inlet end of the air pipe 2, and is used to store the gas pressurized by the first air pump 1 and provide airflow to the air pipe 2. Specifically, the first air pump 1 is a gas compression pump with adjustable speed. When the speed of the gas compression pump is high, the first air pump 1 provides high-pressure gas to the air pipe 2; when the speed of the gas compression pump is low, the first air pump 1 provides low-pressure gas to the air pipe 2.

[0077] The air duct 2 includes a first air duct 21 and a second air duct 22, both of which are connected to the first air tank 4 via a control valve 93. The first air duct 21 and the second air duct 22 are arranged side-by-side, extending circumferentially along the skylight glass 20. The first air duct 21 is a closed high-pressure channel with a relatively small inner diameter; the second air duct 22 is a closed low-pressure channel with a larger inner diameter than the first air duct 21. Specifically, the first air duct 21 has an air inlet connected to a control valve 93. The first air duct 21 also has multiple spaced-apart first air holes 231, each with a high-pressure nozzle 24 for supplying high-pressure airflow into the vehicle 100. The second air duct 22 has an air inlet and an air outlet. The air inlet is connected to the air intake duct 3 via an air valve, and the air outlet is connected to the exhaust duct 7 via the control valve 93. The second air duct 22 also has multiple spaced-apart second air holes 232, each with a low-pressure air outlet 25 for spraying low-pressure airflow into the vehicle or expelling gases from the vehicle. Both the first air holes 231 and the second air holes 232 face the central area of ​​the sunroof glass 20, and are staggered.

[0078] In addition, the second air tank 5, the second air pump 6 and the air filter 92 are all connected in series on the exhaust pipe 7, and the second air tank 5 and the air filter 92 are both located upstream of the second air pump 6 in the airflow direction, with the second air tank 5 located upstream of the air filter 92.

[0079] Furthermore, in this application, multiple functional modes can be achieved by controlling the control valve 93, the first air pump 1, and the second air pump 6. The specific functional modes are shown in the table below:

[0080]

[0081] In the normal heat insulation mode, the second air pump 6 is turned off, the first air pump 1 is turned on and puts the first air pump 1 into high-speed operation mode. At the same time, the control valve 93 connects the air inlet pipe 3 and the first air pipe 21. At this time, high-pressure gas can be sprayed into the center area of ​​the sunroof glass 20 through the high-pressure air nozzle and form an airflow layer in the area of ​​the sunroof glass 20, which can quickly cool down or heat up the sunroof glass 20 and improve the comfort of passengers.

[0082] In air conditioning mode, the second air pump 6 is turned off, the first air pump 1 is turned on and puts the first air pump 1 into low-speed operation mode, and at the same time, the control valve 93 connects the air inlet pipe 3 and the second air pipe 22, and closes the connection channel between the second air pipe 22 and the exhaust pipe 7. At this time, low-pressure gas blows from the low-pressure air outlet 25 to the center of the sunroof glass 20, which can reduce the wind speed and improve the comfort of passengers while ensuring that the roof area is at a comfortable temperature.

[0083] In exhaust mode, the first air pump 1 is turned off, the second air pump 6 is turned on, and the second air duct 22 and the exhaust duct 7 are connected through the control valve 93. This allows the gas inside the vehicle to be drawn into the second air duct 22 through the low-pressure air outlet 25 and discharged to the outside of the vehicle through the exhaust duct 7, which can improve the gas environment inside the vehicle and purify the air inside the vehicle.

[0084] In the strong heat insulation mode, the first air pump 1 is turned on and operates at high speed. The control valve 93 connects the air inlet pipe 3 and the first air pipe 21, the second air pipe 22 and the exhaust pipe 7. At the same time, the second air pump 6 is turned on. In this way, while the high-pressure air nozzle sprays gas into the vehicle, the second air pipe 2 can also exhaust the gas inside the vehicle to the outside, so that the gas inside the vehicle can be flowed, increasing the air circulation in the roof area, thereby increasing the heat dissipation effect of the vehicle 100 roof.

[0085] In the powerful air conditioning mode, the first air pump 1 is turned on and operates at high speed. The control valve 93 opens the air inlets of the first air duct 21 and the second air duct 22, connecting both the first air duct 21 and the second air duct 22 to the air inlet duct 3. At the same time, the control valve 93 controls the opening of the air inlets of the first air duct 21 and the second air duct 22, allowing air to enter both the first air duct 21 and the second air duct 22. This makes the airflow in the roof area stronger than that in the air conditioning mode alone, and gentler than the airflow in the normal heat insulation mode, thereby improving the user's comfort.

[0086] Furthermore, the gas injected into the vehicle through the first air vent 231 and the second air vent 232 varies with the vehicle's air conditioning mode, and can be in three modes: cold air, warm air, and natural wind.

[0087] According to the vehicle 100 of the present invention, by providing the sunroof heat insulation assembly 10 of the first aspect embodiment, and utilizing the plurality of ventilation holes 23 arranged circumferentially along the sunroof glass 20 on the air pipe 2, air can be blown into the central area of ​​the sunroof glass 20 from multiple directions. This forms a flowing airflow layer on the side surface of the sunroof glass 20 facing the vehicle interior, which can carry away the heat at the sunroof glass 20 location through the airflow, thereby improving the temperature of the sunroof glass 10 area. At the same time, it can also block heat from vertically radiating to the occupants of the vehicle, thereby producing a heat insulation effect and improving the heat problem of the head area of ​​the passengers. In addition, it can also reduce the temperature difference between the roof area and other areas of the vehicle interior, increasing the passenger comfort.
