[0002] Car sunroofs primarily provide shade, ventilation, and visual space. Specifically, they effectively block direct sunlight, lower the interior temperature, and reduce UV damage to interior trim and seats. Some sunroofs are made of breathable materials, allowing air to flow and improving ventilation. Their transparency makes the interior appear more spacious and brighter, and some sunroofs offer adjustable transparency. Some sunroofs also have built-in speakers and sound systems, providing entertainment options like music listening. As an exterior decoration, they add a stylish touch to a car and meet personalized needs. In short, a car sunroof is a practical automotive accessory that can significantly enhance the driving and riding experience.

[0003] In the current state of the art, double-layer skylights with built-in sunshades have a hollow space between the two light-transmitting layers, with the curtain fabric of the sunshade assembly located within this hollow space. This hollow space is small and connected to the passenger compartment. When the ambient humidity is high and the temperature fluctuates dramatically, condensation easily occurs. Condensed water droplets cannot escape from the interlayer, leading to the following complaints: Condensed mist obscures vision, causing sensory complaints; condensed water droplets on the sunshade mix together, causing the sunshade to stink over time; and condensed water droplets freeze in low-temperature environments, causing the sunshade to malfunction or deform and damage the fabric.

[0053] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0054] It's important to understand that car sunroofs primarily provide shade, ventilation, and visual space. Specifically, they effectively block direct sunlight, lower the interior temperature, and reduce UV damage to interior trim and seats. Some sunroofs are made of breathable materials, allowing air to flow and improving ventilation. Their transparency makes the interior appear more spacious and brighter, and some sunroofs offer adjustable transparency. Some sunroofs have built-in speakers and sound systems, providing entertainment options like music listening. As an exterior decoration, they add a stylish touch to the car and meet personalized needs. In short, a car sunroof is a practical automotive accessory that can significantly enhance the driving and riding experience.

[0055] The current double-layer skylights with built-in sunshades have a hollow space between the two light-transmitting layers, with the curtain fabric in the sunshade assembly located within this hollow space. This space is small and connected to the passenger compartment. When the ambient humidity is high and the temperature fluctuates dramatically, condensation easily occurs. The condensed water droplets cannot escape from the interlayer, leading to the following complaints: Condensed mist obscures vision, causing sensory complaints; condensed water droplets on the sunshade mix together, causing the sunshade to stink over time; and condensed water droplets freeze in low temperatures, causing the sunshade to malfunction or deform and damage the fabric.

[0056] The present invention provides a double-layered sunshade device, vehicle, and water mist treatment method for the sunshade. A heater connected to a power source dries and heats the unfolded sunshade and the hollow area, converting the water mist into gaseous vapor. Air then removes the vapor, achieving a defrosting and defogging effect. This solves the problem of traditional double-layered sunshades where the mist condenses or even freezes in the middle layer, causing the sunshade to rot, stink, become inoperable, or even become damaged.

[0057] First, as Figure 1 and Figure 2 As shown, an embodiment of the present application provides a double-layer skylight device with a built-in sunshade curtain, which includes: a double-layer skylight body, the double-layer skylight body including a hollow layer area 1, the hollow layer area 1 is provided with a fixed electrode 2; a sunshade curtain 3, the sunshade curtain 3 is arranged in the hollow layer area 1, and the sunshade curtain 3 is fixed with a movable electrode 4; a heater 5, the heater 5 is laid on the sunshade curtain 3, and the heater 5 is electrically connected to the movable electrode 4; a rolling curtain device, the rolling curtain device is connected to the sunshade curtain 3, and the rolling curtain device is configured to drive the sunshade curtain 3 to unwind, so that the movable electrode 4 is inserted into the fixed electrode 2.

[0058] In this embodiment, the sunshade 3 can be unwound or reeled in by the rolling curtain device to ensure normal use. When water mist is detected in the hollow layer area 1, the sunshade 3 can be unwound and spread out by the rolling curtain device until the movable electrode 4 on the sunshade 3 is inserted into the corresponding fixed electrode 2, so that the heater 5 is connected to the power supply to perform drying and heating. The rolled-out sunshade 3 and the hollow layer area 1 are dried and heated, and the water mist is dried into gaseous water vapor. The water vapor is then carried away by the flow of air to achieve a defrosting and defogging effect. This solves the problem of water mist generated in the middle layer of the double-layer canopy condensing or even freezing, causing the sunshade to rot, stink, fail to work, and even damage.

[0059] In combination with the first aspect, in one embodiment, Figure 1 and Figure 2 As shown, a slot 201 is provided on the side of the fixed electrode 2 facing the sunshade 3 , and limiting grooves are provided on both inner side walls of the slot 201 . Both opposite sides of the movable electrode 4 are provided with protrusions adapted to the limiting grooves.

[0060] In this embodiment, see Figure 1 The fixed electrode 2 can be arranged in a rectangular shape and is arranged at the front end of the hollow layer area 1, and a slot 201 is provided on the side wall facing the rear of the fixed electrode 2, and limiting grooves can be provided on the two opposite inner side walls of the slot 201. The opposite sides of the movable electrode 4 are protruded with protrusions adapted to the limiting grooves. When the movable electrode 4 is inserted into the slot 201, the heater 5 is connected to the power supply, and the protrusions move into the corresponding limiting grooves, which can enhance the contact stability between the movable electrode 4 and the fixed electrode 2, and prevent intermittent connection or power failure between the movable electrode 4 and the fixed electrode 2 when the vehicle is bumpy, thereby affecting the normal operation of the heater 5.

[0061] In combination with the first aspect, in one embodiment, Figure 2 As shown, the number of the fixed electrodes 2 and the number of the movable electrodes 4 are both two, and the two fixed electrodes 2 and the two movable electrodes 4 are spaced apart along the width direction of the vehicle body; the number of the heaters 5 is multiple, and the multiple heaters 5 are spaced apart and laid in the sunshade 3 along the length direction of the vehicle body; the multiple heaters 5 are connected in parallel, and the first parallel ends of the multiple heaters 5 are electrically connected to the first movable electrode 4, and the second parallel ends are electrically connected to the second movable electrode 4.

[0062] Among them, two fixed electrodes 2 are fixed at the front end of the hollow layer area 1, and the two fixed electrodes 2 are spaced apart along the width direction of the vehicle body, that is, Figure 2The sunshade curtain 3 is arranged in the hollow layer area 1, and two movable electrodes 4 are fixed at the front end of the sunshade curtain 3. The two movable electrodes 4 are also spaced along the left and right directions and correspond one to one with the two fixed electrodes 2. The heater 5 is laid on the sunshade curtain 3, and the roller blind device can drive the sunshade curtain 3 to unroll or reel in.

[0063] In this embodiment, multiple heaters 5 are provided, spaced apart in the front-to-back direction and connected in parallel. The first parallel ends of the multiple heaters 5 form a first bus, and the second parallel ends form a second bus. The first and second busbars are spaced apart in the left-to-right direction and electrically connected to corresponding movable electrodes 4. This ensures uniform heating of the sunshade 3, stabilizes overall heating, and prevents the risk of fire caused by localized heat concentration.

[0064] In combination with the first aspect, in one embodiment, the number of the fixed electrodes 2 and the number of the movable electrodes 4 are both two, and the two fixed electrodes 2 and the two movable electrodes 4 are spaced apart along the width direction of the vehicle body; the heater 5 includes a PTC heating element, and the PTC heating element is installed in the sunshade 3, and the first end of the PTC heating element is electrically connected to a conductive wire harness 1, and the second end thereof is electrically connected to a conductive wire harness 2; the conductive wire harness 1 is fixed to the first movable electrode 4, and the conductive wire harness 2 is fixed to the second movable electrode 4.

[0065] In this embodiment, the conductive wire harness 1 forms a first bus, the conductive wire harness 2 forms a second bus, the conductive wire harness 1 and the conductive wire harness 2 are spaced apart in the left-right direction, and the length directions of the conductive wire harness 2 and the conductive wire harness 3 are spaced apart in the front-to-back direction, and are laid on the sunshade 3 so as to be retracted and unwound together with the sunshade 3. The PTC heating element is also called a PTC heater, which is composed of a PTC ceramic heating element and an aluminum tube. This type of PTC heating element has the advantages of low thermal resistance and high heat exchange efficiency. It is an automatic constant temperature and energy-saving electric heater. The outstanding feature is the safety performance. Under any application conditions, the surface "redness" phenomenon of electric heating tube heaters will not occur, thereby causing safety hazards such as burns and fire.

[0066] In combination with the first aspect, in one embodiment, the number of the fixed electrodes 2 and the number of the movable electrodes 4 are both two, and the two fixed electrodes 2 and the two movable electrodes 4 are spaced apart along the width direction of the vehicle body; the heater 5 includes a heating wire, and the heating wire is installed in the sunshade 3, and the first ends of the multiple heating wires are electrically connected to a conductive wire bundle 1, and the second ends thereof are electrically connected to a conductive wire bundle 2; the conductive wire bundle 1 is fixed to the first movable electrode 4, and the conductive wire bundle 2 is fixed to the second movable electrode 4.

[0067] In this embodiment, the heater 5 may also be heated by a heating wire or a heating tube, and the heating temperature of the heating wire or the heating tube may be controlled.

[0068] In combination with the first aspect, in one embodiment, the extension path of the heating wire is S-shaped or spiral disc-shaped.

[0069] In this embodiment, the extension path of the heating wire is S-shaped or spiral disc-shaped, so the number of heating wires can be reduced, and the uniform heating effect of the sunshade curtain 3 can also be ensured.

[0070] In combination with the first aspect, in one embodiment, the sunshade curtain 3 includes an inner layer of cloth and an outer layer of cloth fixed to the inner layer of cloth; the heater 5 is laid between the inner layer of cloth and the outer layer of cloth or on the side of the inner layer of cloth facing away from the outer layer of cloth.

[0071] In this embodiment, the curtain fabric of the sunshade curtain 3 includes an inner layer and an outer layer. The heater 5 is arranged on the inner layer, and the outer layer can be made of antibacterial and waterproof fibers woven together.

[0072] In combination with the first aspect, in one embodiment, the rolling curtain device includes: a unwinding shaft, the unwinding shaft is provided with a torsion spring, the sunshade curtain 3 is wound on the outer wall of the unwinding shaft, and the elastic force of the torsion spring tends to pull the sunshade curtain 3 to reel; a winding motor, a winding wheel is fixed to the output end of the winding motor, and the winding wheel and the unwinding shaft are spaced apart along the length direction of the vehicle body; a winding rope, one end of the winding rope is connected to the starting end of the sunshade curtain 3, and the other end thereof is connected to the winding wheel.

[0073] In this embodiment, the operating principle of the rolling curtain device primarily relies on the coordinated action of a torsion spring, a winding motor, and a winding cord. Specifically, in the initial state, the sunshade 3 is wound around the outer wall of the unwinding shaft. The torsion spring is in a state of stored force, and its elastic force tends to pull the sunshade 3 to rewind, thereby keeping the sunshade 3 automatically retracted unless otherwise affected by external forces. When the sunshade 3 needs to be unfolded, the winding motor is activated, and the winding reel, fixed to its output end, begins to rotate. Because one end of the winding cord is connected to the starting end of the sunshade 3 and the other end is connected to the winding reel, the rotation of the winding reel pulls the winding cord, which in turn drives the sunshade 3 to unfold from the unwinding shaft. When the sunshade 3 needs to be retracted, the winding motor rotates in the reverse direction, and the winding reel rotates in the reverse direction, releasing the winding cord. At this point, the elastic force of the torsion spring begins to act, pulling the sunshade 3 back onto the outer wall of the unwinding shaft. The forward and reverse rotation of the winding motor enables automatic unfolding and rewinding of the sunshade 3, improving user convenience. When not in use, the sunshade 3 automatically retracts onto the outer wall of the reel, saving space inside the vehicle. The elastic force of the torsion spring helps maintain the sunshade 3's tension, preventing it from loosening and causing noise or damage during driving. The automatic deployment and retraction of the sunshade 3 allows passengers to adjust the interior light and temperature as needed, enhancing passenger comfort.

[0074] In combination with the first aspect, in one embodiment, Figure 1 As shown, the double-layer skylight body includes: an outer layer of glass 6 and an inner layer of glass 7. The outer layer of glass 6 and the inner layer of glass 7 are arranged in parallel and spaced apart along the height direction of the vehicle body to form the hollow layer area 1.

[0075] In this embodiment, the outer glass 6 can be laminated glass or single-layer glass; the inner glass 7 is tempered glass; Figure 1 The outer layer of glass 6 is laminated glass.

[0076] In combination with the first aspect, in one embodiment, Figure 1 and Figure 2 As shown, a support 8 is fixed to the inner side of one end of the outer layer of glass 6 close to the front of the vehicle, and the support 8 is fixed to the front crossbeam 10 via bolts 9. One end of the inner layer of glass 7 is fixed to the front crossbeam 10 via glue 11; the fixed electrode 2 is fixed to the front crossbeam 10, and the fixed electrode 2 is used to be electrically connected to the vehicle heating control system via a conductive harness 3 12.

[0077] In this embodiment, the working principle mainly involves the interaction and connection between the support 8, the front crossbeam 10, the inner glass 7 and the fixed electrode 2. A support 8 is fixed to the inner side of the end of the outer glass 6 close to the front of the vehicle, and the support 8 is firmly fixed to the front crossbeam 10 by a bolt 9. One end of the inner glass 7 is glued and fixed to the front crossbeam 10 by glue 11, forming a stable structural connection. The two fixed electrodes 2 are fixed to the front crossbeam 10 and are electrically connected to the vehicle heating control system through the conductive harness three 12. In this way, the fixed electrode 2 can receive electrical signals and control instructions from the vehicle heating control system. When the vehicle heating control system issues a heating instruction, the electrical signal is transmitted to the fixed electrode 2 through the conductive harness three 12, thereby heating the sunshade 3.

[0078] In combination with the first aspect, in one embodiment, the double-layer skylight device with built-in sunshade includes: a frame, the outer layer of glass 6 and the inner layer of glass 7 are fixed to the frame, the frame is fixed with two guide rails, the length direction of the guide rails extends along the length direction of the vehicle body, and the two guide rails are spaced apart along the width direction of the vehicle body; a sunshade pull rod 13 is fixed to the starting end of the sunshade 3, and the two ends of the sunshade pull rod 13 are slidably connected in the two guide rails.

[0079] In this embodiment, both the outer glass 6 and the inner glass 7 are fixed to the frame, forming a stable double-layer canopy structure. Furthermore, two guide rails are fixed to the frame. These rails extend along the length of the vehicle body and are spaced apart across the width of the vehicle body, providing a sliding path for the sunshade 3. A sunshade rod 13 is fixed to the starting end of the sunshade 3, and its ends are slidably connected to the two guide rails. This allows the sunshade rod 13 to slide within the guide rails, thereby moving the sunshade 3 to expand or retract along the length of the rails. When sunshade protection is required, the sunshade rod 13 can be manually or electrically pushed, sliding it along the guide rails. This causes the sunshade 3 to expand and block the space between the outer glass 6 and the inner glass 7, thus providing sunshade protection. When sunshade protection is no longer required, the sunshade rod 13 can be pushed in the opposite direction to retract the sunshade 3. The expansion and contraction of the sunshade 3 allows for flexible control of the light and temperature inside the vehicle, enhancing passenger comfort. The sunshade 3 provides a particularly effective shade when the sun is strong or when privacy needs to be protected. When retracted, the sunshade 3 takes up little space and does not affect other functions or usable space in the vehicle. At the same time, the double-layer canopy structure fully utilizes the roof space, providing passengers with a more spacious and comfortable riding environment. Whether manually or electrically operated, the sunshade lever 13 slides very smoothly, making the deployment and folding of the sunshade 3 very simple and convenient. This also improves the user experience and satisfaction of passengers.

[0080] Second, as Figure 1 and Figure 2 As shown, an embodiment of the present application provides a vehicle, which includes: a double-layer skylight body, the double-layer skylight body includes a hollow layer area 1, and the hollow layer area 1 is provided with a fixed electrode 2; a sunshade curtain 3, the sunshade curtain 3 is arranged in the hollow layer area 1, and the sunshade curtain 3 is fixed with a movable electrode 4; a heater 5, the heater 5 is laid on the sunshade curtain 3, and the heater 5 is electrically connected to the movable electrode 4; a rolling curtain device, the rolling curtain device is connected to the sunshade curtain 3, and the rolling curtain device is configured to drive the sunshade curtain 3 to unwind, so that the movable electrode 4 is inserted into the fixed electrode 2.

[0081] Specifically, the rolling curtain device can be used to unwind or rewind the sunshade curtain 3 to ensure normal use. When water mist is found in the hollow layer area 1, the rolling curtain device can be used to unwind and spread the sunshade curtain 3 until the movable electrode 4 on the sunshade curtain 3 is inserted into the corresponding fixed electrode 2, so that the heater 5 is connected to the power supply for drying and heating. The rolled-out sunshade curtain 3 and the hollow layer area 1 are dried and heated, and the water mist is dried into gaseous water vapor. The water vapor is then carried away by the flow of air to achieve a defrosting and defogging effect. This solves the problem of water mist generated in the middle layer of the double-layer canopy condensing or even freezing, causing the sunshade curtain to rot, stink, fail to work, and even be damaged.

[0082] In combination with the second aspect, in one embodiment, the vehicle heating control system includes: a power supply; a controller, the controller is electrically connected to the power supply; a humidity sensor, the humidity sensor is installed in the hollow layer area 1, the humidity sensor is electrically connected to the controller; and a skylight heating switch, the skylight heating switch is electrically connected to the controller and the two fixed electrodes 2.

[0083] In this embodiment, the power supply provides the required electrical energy for the entire heating control system. A humidity sensor is installed in the hollow layer area 1 to monitor the humidity in that area in real time. The humidity sensor is electrically connected to the controller and transmits the detected humidity signal to the controller. After receiving the humidity signal from the humidity sensor, the controller processes it and determines whether to activate the heating function. For example, when the humidity reaches a certain threshold, the controller may determine that heating is necessary to remove moisture or prevent fogging. When the skylight heating switch is turned on and the controller determines that heating is necessary, it sends a heating command to the two fixed electrodes 2. After the fixed electrodes 2 receive the command, heater 5 is connected to the circuit to start heating. During the heating process, the controller may continuously receive signals from the humidity sensor to monitor the heating effect and adjust the heating strategy accordingly. Heating the sunshade 3 effectively removes fog or frost, improves the transparency of the windows, and thus enhances driving safety. In cold or humid weather, the heating function can increase the temperature inside the vehicle, providing a more comfortable riding environment for passengers. The combination of the humidity sensor and the skylight heating switch enables intelligent control of the heating function. The system can automatically adjust the heating status based on actual humidity and passenger needs, improving user convenience and energy efficiency. The heating function can also effectively prevent condensation and corrosion in the hollow layer area 1, thereby extending the service life of the sunshade 3.

[0084] In combination with the second aspect, in one embodiment, the humidity sensor can also be replaced by a temperature sensor. For example, when the external temperature is <-15°C, the heater 5 heats for 20 minutes; when the external temperature is -15°C to 0°C, the heater 5 heats for 15 minutes; when the external temperature is 0°C to 30°C, the heater 5 heats for 10 minutes; when the external temperature is >30°C, the heater 5 heats for 1 minute. In actual use, different continuous heating times can be used according to customer needs.

[0085] In conjunction with the second aspect, in one embodiment, Figure 1 and Figure 2 As shown, a slot 201 is provided on the side of the fixed electrode 2 facing the sunshade 3 , and limiting grooves are provided on both inner side walls of the slot 201 . Both opposite sides of the movable electrode 4 are provided with protrusions adapted to the limiting grooves.

[0086] In this embodiment, see Figure 1The fixed electrode 2 can be arranged in a rectangular shape and is arranged at the front end of the hollow layer area 1, and a slot 201 is provided on the side wall facing the rear of the fixed electrode 2, and limiting grooves can be provided on the two opposite inner side walls of the slot 201. The opposite sides of the movable electrode 4 are protruded with protrusions adapted to the limiting grooves. When the movable electrode 4 is inserted into the slot 201, the heater 5 is connected to the power supply, and the protrusions move into the corresponding limiting grooves, which can enhance the contact stability between the movable electrode 4 and the fixed electrode 2, and prevent intermittent connection or power failure between the movable electrode 4 and the fixed electrode 2 when the vehicle is bumpy, thereby affecting the normal operation of the heater 5.

[0087] In conjunction with the second aspect, in one embodiment, Figure 2 As shown, the number of the fixed electrodes 2 and the number of the movable electrodes 4 are both two, and the two fixed electrodes 2 and the two movable electrodes 4 are spaced apart along the width direction of the vehicle body; the number of the heaters 5 is multiple, and the multiple heaters 5 are spaced apart and laid in the sunshade 3 along the length direction of the vehicle body; the multiple heaters 5 are connected in parallel, and the first parallel ends of the multiple heaters 5 are electrically connected to the first movable electrode 4, and the second parallel ends are electrically connected to the second movable electrode 4.

[0088] Among them, two fixed electrodes 2 are fixed at the front end of the hollow layer area 1, and the two fixed electrodes 2 are spaced apart along the width direction of the vehicle body, that is, Figure 2 The sunshade curtain 3 is arranged in the hollow layer area 1, and two movable electrodes 4 are fixed at the front end of the sunshade curtain 3. The two movable electrodes 4 are also spaced along the left and right directions and correspond one to one with the two fixed electrodes 2. The heater 5 is laid on the sunshade curtain 3, and the roller blind device can drive the sunshade curtain 3 to unroll or reel in.

[0089] In this embodiment, multiple heaters 5 are provided, spaced apart in the front-to-back direction and connected in parallel. The first parallel ends of the multiple heaters 5 form a first bus, and the second parallel ends form a second bus. The first and second busbars are spaced apart in the left-to-right direction and electrically connected to corresponding movable electrodes 4. This ensures uniform heating of the sunshade 3, stabilizes overall heating, and prevents the risk of fire caused by localized heat concentration.

[0090] In combination with the second aspect, in one embodiment, the number of the fixed electrodes 2 and the number of the movable electrodes 4 are both two, and the two fixed electrodes 2 and the two movable electrodes 4 are spaced apart along the width direction of the vehicle body; the heater 5 includes a PTC heating element, and the PTC heating element is installed in the sunshade 3, and the first end of the PTC heating element is electrically connected to a conductive wire harness 1, and the second end thereof is electrically connected to a conductive wire harness 2; the conductive wire harness 1 is fixed to the first movable electrode 4, and the conductive wire harness 2 is fixed to the second movable electrode 4.

[0091] In this embodiment, the conductive wire harness 1 forms a first bus, the conductive wire harness 2 forms a second bus, the conductive wire harness 1 and the conductive wire harness 2 are spaced apart in the left-right direction, and the length directions of the conductive wire harness 2 and the conductive wire harness 3 are spaced apart in the front-to-back direction, and are laid on the sunshade 3 so as to be retracted and unwound together with the sunshade 3. The PTC heating element is also called a PTC heater, which is composed of a PTC ceramic heating element and an aluminum tube. This type of PTC heating element has the advantages of low thermal resistance and high heat exchange efficiency. It is an automatic constant temperature and energy-saving electric heater. The outstanding feature is the safety performance. Under any application conditions, the surface "redness" phenomenon of electric heating tube heaters will not occur, thereby causing safety hazards such as burns and fire.

[0092] In combination with the second aspect, in one embodiment, the number of the fixed electrodes 2 and the number of the movable electrodes 4 are both two, and the two fixed electrodes 2 and the two movable electrodes 4 are spaced apart along the width direction of the vehicle body; the heater 5 includes a heating wire, and the heating wire is installed in the sunshade 3, and the first ends of the multiple heating wires are electrically connected to a conductive wire bundle 1, and the second ends thereof are electrically connected to a conductive wire bundle 2; the conductive wire bundle 1 is fixed to the first movable electrode 4, and the conductive wire bundle 2 is fixed to the second movable electrode 4.

[0093] In this embodiment, the heater 5 may also be heated by a heating wire or a heating tube, and the heating temperature of the heating wire or the heating tube may be controlled.

[0094] In combination with the second aspect, in one embodiment, the extension path of the heating wire is S-shaped or spiral disc-shaped.

[0095] In this embodiment, the extension path of the heating wire is S-shaped or spiral disc-shaped, so the number of heating wires can be reduced, and the uniform heating effect of the sunshade curtain 3 can also be ensured.

[0096] In combination with the second aspect, in one embodiment, the sunshade curtain 3 includes an inner layer of cloth and an outer layer of cloth fixed to the inner layer of cloth; the heater 5 is laid between the inner layer of cloth and the outer layer of cloth or on the side of the inner layer of cloth facing away from the outer layer of cloth.

[0097] In this embodiment, the curtain fabric of the sunshade curtain 3 includes an inner layer and an outer layer. The heater 5 is arranged on the inner layer, and the outer layer can be made of antibacterial and waterproof fibers woven together.

[0098] In combination with the second aspect, in one embodiment, the rolling curtain device includes: a unwinding shaft, the unwinding shaft is provided with a torsion spring, the sunshade curtain 3 is wound on the outer wall of the unwinding shaft, and the elastic force of the torsion spring tends to pull the sunshade curtain 3 to reel; a winding motor, a winding wheel is fixed to the output end of the winding motor, and the winding wheel and the unwinding shaft are spaced apart along the length direction of the vehicle body; a winding rope, one end of the winding rope is connected to the starting end of the sunshade curtain 3, and the other end thereof is connected to the winding wheel.

[0099] In this embodiment, the operating principle of the rolling curtain device primarily relies on the coordinated action of a torsion spring, a winding motor, and a winding cord. Specifically, in the initial state, the sunshade 3 is wound around the outer wall of the unwinding shaft. The torsion spring is in a state of stored force, and its elastic force tends to pull the sunshade 3 to rewind, thereby keeping the sunshade 3 automatically retracted unless otherwise affected by external forces. When the sunshade 3 needs to be unfolded, the winding motor is activated, and the winding reel, fixed to its output end, begins to rotate. Because one end of the winding cord is connected to the starting end of the sunshade 3 and the other end is connected to the winding reel, the rotation of the winding reel pulls the winding cord, which in turn drives the sunshade 3 to unfold from the unwinding shaft. When the sunshade 3 needs to be retracted, the winding motor rotates in the reverse direction, and the winding reel rotates in the reverse direction, releasing the winding cord. At this point, the elastic force of the torsion spring begins to act, pulling the sunshade 3 back onto the outer wall of the unwinding shaft. The forward and reverse rotation of the winding motor enables automatic unfolding and rewinding of the sunshade 3, improving user convenience. When not in use, the sunshade 3 automatically retracts onto the outer wall of the reel, saving space inside the vehicle. The elastic force of the torsion spring helps maintain the sunshade 3's tension, preventing it from loosening and causing noise or damage during driving. The automatic deployment and retraction of the sunshade 3 allows passengers to adjust the interior light and temperature as needed, enhancing passenger comfort.

[0100] In conjunction with the second aspect, in one embodiment, Figure 1 As shown, the double-layer skylight body includes: an outer layer of glass 6 and an inner layer of glass 7. The outer layer of glass 6 and the inner layer of glass 7 are arranged in parallel and spaced apart along the height direction of the vehicle body to form the hollow layer area 1.

[0101] In this embodiment, the outer glass 6 can be laminated glass or single-layer glass; the inner glass 7 is tempered glass; Figure 1 The outer layer of glass 6 is laminated glass.

[0102] In conjunction with the second aspect, in one embodiment, Figure 1 and Figure 2As shown, a support 8 is fixed to the inner side of one end of the outer layer of glass 6 close to the front of the vehicle, and the support 8 is fixed to the front crossbeam 10 via bolts 9. One end of the inner layer of glass 7 is fixed to the front crossbeam 10 via glue 11; the fixed electrode 2 is fixed to the front crossbeam 10, and the fixed electrode 2 is used to be electrically connected to the vehicle heating control system via a conductive harness 3 12.

[0103] In this embodiment, the working principle mainly involves the interaction and connection between the support 8, the front crossbeam 10, the inner glass 7 and the fixed electrode 2. A support 8 is fixed to the inner side of the end of the outer glass 6 close to the front of the vehicle, and the support 8 is firmly fixed to the front crossbeam 10 by a bolt 9. One end of the inner glass 7 is glued and fixed to the front crossbeam 10 by glue 11, forming a stable structural connection. The two fixed electrodes 2 are fixed to the front crossbeam 10 and are electrically connected to the vehicle heating control system through the conductive harness three 12. In this way, the fixed electrode 2 can receive electrical signals and control instructions from the vehicle heating control system. When the vehicle heating control system issues a heating instruction, the electrical signal is transmitted to the fixed electrode 2 through the conductive harness three 12, thereby heating the sunshade 3.

[0104] In combination with the second aspect, in one embodiment, the double-layer skylight device with built-in sunshade includes: a frame, the outer layer of glass 6 and the inner layer of glass 7 are fixed to the frame, the frame is fixed with two guide rails, the length direction of the guide rails extends along the length direction of the vehicle body, and the two guide rails are spaced apart along the width direction of the vehicle body; a sunshade pull rod 13 is fixed to the starting end of the sunshade 3, and the two ends of the sunshade pull rod 13 are slidably connected in the two guide rails.

[0105] In this embodiment, both the outer glass 6 and the inner glass 7 are fixed to the frame, forming a stable double-layer canopy structure. Furthermore, two guide rails are fixed to the frame. These rails extend along the length of the vehicle body and are spaced apart across the width of the vehicle body, providing a sliding path for the sunshade 3. A sunshade rod 13 is fixed to the starting end of the sunshade 3, and its ends are slidably connected to the two guide rails. This allows the sunshade rod 13 to slide within the guide rails, thereby moving the sunshade 3 to expand or retract along the length of the rails. When sunshade protection is required, the sunshade rod 13 can be manually or electrically pushed, sliding it along the guide rails. This causes the sunshade 3 to expand and block the space between the outer glass 6 and the inner glass 7, thus providing sunshade protection. When sunshade protection is no longer required, the sunshade rod 13 can be pushed in the opposite direction to retract the sunshade 3. The expansion and contraction of the sunshade 3 allows for flexible control of the light and temperature inside the vehicle, enhancing passenger comfort. The sunshade 3 provides a particularly effective shade when the sun is strong or when privacy needs to be protected. When retracted, the sunshade 3 takes up little space and does not affect other functions or usable space in the vehicle. At the same time, the double-layer canopy structure fully utilizes the roof space, providing passengers with a more spacious and comfortable riding environment. Whether manually or electrically operated, the sunshade lever 13 slides very smoothly, making the deployment and folding of the sunshade 3 very simple and convenient. This also improves the user experience and satisfaction of passengers.

[0106] In a third aspect, embodiments of the present application provide a method for treating water mist condensation on a canopy using a double-layer canopy device with a built-in sunshade as described in some of the above embodiments, comprising the following steps:

[0107] S100: Obtaining humidity parameters in the hollow layer area 1 monitored by the humidity sensor;

[0108] S200: If the humidity parameter in the hollow layer area 1 is lower than the set threshold and the sunshade curtain 3 is not in a fully expanded state, the roller blind device is controlled to unwind until the movable electrode 4 is inserted into the fixed electrode 2, so that the heater 5 is connected to the circuit and the heating time is set.

[0109] In this embodiment, the combination of steps S100 and S200 enables intelligent monitoring and response to the humidity in the vehicle's hollow area 1. The humidity sensor monitors the humidity parameters in the hollow area 1 in real time, ensuring immediate awareness of changes in the vehicle's interior environment. When the humidity parameter in the hollow area 1 falls below a set threshold and the sunshade 3 is not fully extended, the system automatically controls the rolling device to unwind. This operation helps heat the entire unrolled sunshade 3 and the hollow area 1 by unfolding the sunshade 3 when humidity is low. After the movable electrode 4 is inserted into the corresponding fixed electrode 2, the heater 5 is connected to the circuit and begins heating for a set time. This helps quickly raise the temperature in the hollow area 1, thereby removing moisture or preventing fogging, keeping the sunshade 3 dry overall. By automatically adjusting the sunshade heating function, the system helps maintain a stable and comfortable interior environment. It also enhances driving safety. The heating function is activated only under specific conditions (when the humidity is below the threshold and the sunshade is not fully extended), which helps avoid unnecessary energy consumption and optimize energy efficiency. In summary, this control logic not only improves driving safety and comfort, but also optimizes the vehicle's energy efficiency through intelligent monitoring and response mechanisms.

[0110] In conjunction with the third aspect, in one embodiment, after S200, the following steps are included:

[0111] S300: Control the vehicle to start external circulation, so that the water mist is dried into gaseous water vapor and discharged outside the vehicle.

[0112] In this embodiment, step S200 monitors the humidity in the hollow area 1 in real time and automatically triggers a series of actions, including unwinding the sunshade 3 and activating the heater 5, when the humidity falls below a set threshold. This step ensures that the system can respond quickly when the humidity in the hollow area is too low, improving the interior environment by adjusting and heating the sunshade 3. Unwinding the sunshade 3 not only helps adjust the light inside the vehicle, but activating the heater 5 directly raises the temperature in the hollow area 1, helping to remove moisture and prevent fogging. Step S300 activates the vehicle's external circulation system, evaporating the mist in the hollow area 1 into gas and discharging it outside the vehicle. This operation further reduces the humidity in the hollow area 1 and prevents moisture accumulation inside the vehicle. By comprehensively regulating humidity, temperature, and light, these two steps create a more comfortable and pleasant interior environment for the driver and passengers. Clear windows and appropriate interior humidity also enhance driving safety and the overall driving experience. The system activates the heater 5 and external circulation system only when needed, helping to reduce unnecessary energy consumption. By effectively managing humidity in the car, mold growth and odor problems caused by excessive humidity can be reduced, thereby improving the quality of the air inside the car. In short, this provides the driver and passengers with the best in-car environment experience.

[0113] In conjunction with the third aspect, in one embodiment, after S200, the following steps are included:

[0114] S300: Control the vehicle to open the windows, so that the water mist is dried into gaseous water vapor and discharged outside the vehicle.

[0115] Of course, in some embodiments, the car windows can also be controlled to open to discharge the evaporated gas from the water mist outside the car.
