In short, the car skylight is a practical car accessory that can significantly enhance the driving and riding experience.

[0055] Among them, the double-layer skylight with built-in sunshade has a hollow layer between the double light-transmitting layers, and the curtain in the sunshade assembly is located in the hollow layer. The gap in the hollow layer is small and is connected to the passenger compartment. When the ambient humidity is high and the temperature changes drastically, water mist condensation is likely to occur. The condensed water droplets cannot come out in the interlayer, which will cause the following complaints: condensed mist blocks the line of sight and causes perception complaints; the condensed water droplets on the sunshade are mixed together, which can easily cause the sunshade to stink after a long time; the condensed water droplets freeze the curtain in a low temperature environment, causing the sunshade to fail to work or the curtain to deform and damage.

This solves the problem that the water mist generated in the middle layer area of ​​the traditional double-layer awning condenses or even freezes, causing the sunshade to rot and stink, fail to work and be 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, 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 3, the sunshade 3 is arranged in the hollow layer area 1, and the sunshade 3 is fixed with a movable electrode 4; a heater 5, the heater 5 is laid on the sunshade 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 3, and the rolling curtain device is configured to drive the sunshade 3 to unwind, so that the movable electrode 4 is inserted into the fixed electrode 2.

When water mist is found in the hollow layer area 1, the sunshade curtain 3 can be unrolled and spread out by the rolling curtain device 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, and the spread sunshade curtain 3 and the hollow layer area 1 are dried and heated to dry the water mist into gaseous water vapor, and then the water vapor is taken away by the flow of air to achieve the defrosting and defog effect. The problem of water mist condensing or even freezing in the middle layer area of ​​the double-layer skylight, which causes the sunshade curtain to rot and stink, fail to work, and be damaged, is solved.

[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 the two inner side walls of the slot 201. Both opposite sides of the movable electrode 4 are provided with protrusions matched with the limiting grooves.

[0060] In this embodiment, see Figure 1 The fixed electrode 2 can be arranged in a rectangular shape and arranged at the front end of the hollow layer area 1, and a slot 201 is provided on the side wall of the fixed electrode 2 facing the rear, and limiting grooves can be provided on the two opposite inner walls of the slot 201. The opposite sides of the movable electrode 4 are convexly provided 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 are moved into the corresponding limiting grooves, which can enhance the contact stability between the movable electrode 4 and the fixed electrode 2, and prevent the 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 inside 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 thereof 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 apart along the left and right directions and correspond one by one to the two fixed electrodes 2. The heater 5 is laid on the sunshade curtain 3, and the rolling curtain device can drive the sunshade curtain 3 to unroll or roll up.

[0063] In this embodiment, there are multiple heaters 5, which are spaced apart in the front-to-back direction, and are 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 bus and the second bus are spaced apart in the left-right direction and are electrically connected to the corresponding active electrodes 4. The sunshade 3 can be heated evenly, and the overall heating is stable, which prevents the risk of fire caused by local heating temperature 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 heater, and the PTC heater is installed in the sunshade 3, and the first end of the PTC heater 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 the present embodiment, conductive wire harness 1 forms a first bus, conductive wire harness 2 forms a second bus, conductive wire harness 1 and conductive wire harness 2 are spaced apart in the left-right direction, and the length directions of conductive wire harness 2 and conductive wire harness 3 are spaced apart in the front-back direction, and 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 power-saving electric heater. The outstanding feature lies in the safety performance. In any application situation, the surface "redness" phenomenon such as 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 heating wires, and the heating wires are installed in the sunshade 3, and the first ends of the plurality of 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 implementation, 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 of fabric and an outer layer of fabric, the inner layer of which is provided with a heater 5, and the outer layer can be made of antibacterial and waterproof fibers interwoven 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 around the outer wall of the unwinding shaft, and the elastic force of the torsion spring tends to pull the sunshade curtain 3 to reel in; 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 working principle of the rolling curtain device mainly depends on the synergistic effect of the torsion spring, the winding motor and the winding rope. Specifically, in the initial state: the sunshade curtain 3 is wound on the outer wall of the unwinding shaft, the torsion spring is in a certain force storage state, and its elastic force tends to pull the sunshade curtain 3 to roll up, that is, to keep the sunshade curtain 3 automatically rolled up when it is not acted upon by external force. When the sunshade curtain 3 needs to be unfolded, the winding motor is started, and the winding wheel fixed at its output end begins to rotate. Since one end of the winding rope is connected to the starting end of the sunshade curtain 3 and the other end is connected to the winding wheel, the rotation of the winding wheel will pull the winding rope, thereby driving the sunshade curtain 3 to unfold from the unwinding shaft. When the sunshade curtain 3 needs to be rolled up, the winding motor rotates in the opposite direction, and the winding wheel rotates in the opposite direction accordingly, releasing the winding rope. At this time, the elastic force of the torsion spring begins to appear, pulling the sunshade curtain 3 to roll back to the outer wall of the unwinding reel. Through the forward and reverse rotation of the winding motor, the automatic unfolding and winding of the sunshade curtain 3 is realized, and the convenience of use is improved. The sunshade 3 can be automatically rolled back onto the outer wall of the reel when not in use, saving space in the vehicle. The elastic force of the torsion spring helps to keep the sunshade 3 in a tight state, preventing it from making noise or being damaged due to looseness during driving. The automatic unfolding and retracting function of the sunshade 3 allows passengers to adjust the light and temperature in the vehicle at any time as needed, thereby improving riding 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 in the height direction of the vehicle body to form the hollow layer area 1.

[0075] In this embodiment, the outer glass 6 can be a laminated glass or a single-layer glass; the inner glass 7 is a tempered glass; Figure 1 The outer layer of glass 6 used in the invention 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 a front cross beam 10 via bolts 9. One end of the inner layer of glass 7 is fixed to the front cross beam 10 via glue 11; the fixed electrode 2 is fixed to the front cross beam 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 mode of the support 8, the front cross beam 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 cross beam 10 by bolts 9. One end of the inner glass 7 is glued and fixed to the front cross beam 10 by glue 11, forming a stable structural connection. The two fixed electrodes 2 are fixed to the front cross beam 10 and electrically connected to the vehicle heating control system through the conductive wire 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 wire harness three 12, and then the sunshade 3 is heated.

[0078] In combination with the first aspect, in one embodiment, the double-layer skylight device with built-in sunshade includes: a frame, the outer glass 6 and the inner 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 rod 13 is fixed to the starting end of the sunshade 3, and the two ends of the sunshade rod 13 are slidably connected in the two guide rails.

[0079] In this embodiment, the outer glass 6 and the inner glass 7 are fixed on the frame to form a stable double-layer canopy structure. At the same time, two guide rails are fixed on the frame. The two guide rails extend along the length direction of the vehicle body and are spaced apart along the width direction of the vehicle body, providing a path for the sliding of the sunshade 3. A sunshade pull rod 13 is fixed at 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. In this way, the sunshade pull rod 13 can slide in the guide rail, thereby driving the sunshade 3 to unfold or retract along the length direction of the guide rail. When sunshade is needed, the sunshade pull rod 13 can be pushed manually or electrically to slide along the guide rail, thereby driving the sunshade 3 to unfold, block the space between the outer glass 6 and the inner glass 7, and realize the sunshade function. When sunshade is not needed, the sunshade pull rod 13 can be pushed in the opposite direction to retract the sunshade 3. Through the unfolding and retracting of the sunshade 3, the light and temperature in the car can be flexibly controlled to improve the riding comfort. Especially when the sun is strong or the privacy in the car needs to be protected, the sunshade effect of the sunshade 3 is particularly obvious. When the sunshade 3 is folded, it takes up little space and will not affect other functions and usage space in the car. At the same time, the double-layer skylight structure also makes full use of the space on the roof, providing passengers with a more spacious and comfortable riding environment. Whether it is manual or electric, the sliding of the sunshade pull rod 13 is very smooth, making the unfolding 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 unroll so that the movable electrode 4 is inserted into the fixed electrode 2.

[0081] Specifically, the sunshade curtain 3 can be unrolled or rolled up by the rolling curtain device to ensure normal use. When water mist is found in the hollow layer area 1, the sunshade curtain 3 can be unrolled and spread out by the rolling curtain device 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, and the spread sunshade curtain 3 and the hollow layer area 1 are dried and heated to dry the water mist into gaseous water vapor, and then the water vapor is taken away by the flow of air to achieve the defrosting and defogging effect. The problem of water mist condensing or even freezing in the middle layer area of ​​the double-layer skylight, which causes the sunshade curtain to rot and stink, fail to work, and be damaged, is solved.

[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; the 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 electric energy for the entire heating control system. The humidity sensor is installed in the hollow layer area 1 for real-time detection of the humidity in the area. The humidity sensor is electrically connected to the controller and transmits the detected humidity signal to the controller. After receiving the humidity signal transmitted by the humidity sensor, the controller processes it and determines whether the heating function needs to be started. For example, when the humidity reaches a certain threshold, the controller may determine that heating is required to remove moisture or prevent fogging. When the skylight heating switch is turned on and the controller determines that heating is required, the controller sends a heating instruction to the two fixed electrodes 2. After the fixed electrode 2 receives the instruction, the heater 5 is connected to the circuit for heating. During the heating process, the controller may continue to receive the signal of the humidity sensor to monitor the heating effect and adjust the heating strategy in time. By heating the sunshade 3, fog or frost can be effectively removed, the transparency of the car window can be improved, and the driving safety can be enhanced. In cold or humid weather, the heating function can increase the temperature in the car and provide passengers with a more comfortable riding environment. The use of the humidity sensor and the skylight heating switch realizes the intelligent control of the heating function. The system can automatically adjust the heating state according to the actual humidity and passenger needs, which improves the convenience and energy efficiency of use. 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 implementation, 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 the two inner side walls of the slot 201. Both opposite sides of the movable electrode 4 are provided with protrusions matched with the limiting grooves.

[0086] In this embodiment, see Figure 1The fixed electrode 2 can be arranged in a rectangular shape and arranged at the front end of the hollow layer area 1, and a slot 201 is provided on the side wall of the fixed electrode 2 facing the rear, and limiting grooves can be provided on the two opposite inner walls of the slot 201. The opposite sides of the movable electrode 4 are convexly provided 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 are moved into the corresponding limiting grooves, which can enhance the contact stability between the movable electrode 4 and the fixed electrode 2, and prevent the 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 implementation, 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 inside 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 thereof 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 apart along the left and right directions and correspond one by one to the two fixed electrodes 2. The heater 5 is laid on the sunshade curtain 3, and the rolling curtain device can drive the sunshade curtain 3 to unroll or roll up.

[0089] In this embodiment, there are multiple heaters 5, which are spaced apart in the front-to-back direction, and are 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 bus and the second bus are spaced apart in the left-right direction and are electrically connected to the corresponding active electrodes 4. The sunshade 3 can be heated evenly, and the overall heating is stable, which prevents the risk of fire caused by local heating temperature 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 heater, and the PTC heater is installed in the sunshade 3, and the first end of the PTC heater 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 the present embodiment, conductive wire harness 1 forms a first bus, conductive wire harness 2 forms a second bus, conductive wire harness 1 and conductive wire harness 2 are spaced apart in the left-right direction, and the length directions of conductive wire harness 2 and conductive wire harness 3 are spaced apart in the front-back direction, and 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 power-saving electric heater. The outstanding feature lies in the safety performance. In any application situation, the surface "redness" phenomenon such as 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 plurality of 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 implementation, 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 of fabric and an outer layer of fabric, the inner layer of which is provided with a heater 5, and the outer layer can be made of antibacterial and waterproof fibers interwoven 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 around the outer wall of the unwinding shaft, and the elastic force of the torsion spring tends to pull the sunshade curtain 3 to reel in; 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 working principle of the rolling curtain device mainly depends on the synergistic effect of the torsion spring, the winding motor and the winding rope. Specifically, in the initial state: the sunshade curtain 3 is wound on the outer wall of the unwinding shaft, the torsion spring is in a certain force storage state, and its elastic force tends to pull the sunshade curtain 3 to roll up, that is, to keep the sunshade curtain 3 automatically rolled up when it is not acted upon by external force. When the sunshade curtain 3 needs to be unfolded, the winding motor is started, and the winding wheel fixed at its output end begins to rotate. Since one end of the winding rope is connected to the starting end of the sunshade curtain 3 and the other end is connected to the winding wheel, the rotation of the winding wheel will pull the winding rope, thereby driving the sunshade curtain 3 to unfold from the unwinding shaft. When the sunshade curtain 3 needs to be rolled up, the winding motor rotates in the opposite direction, and the winding wheel rotates in the opposite direction accordingly, releasing the winding rope. At this time, the elastic force of the torsion spring begins to appear, pulling the sunshade curtain 3 to roll back to the outer wall of the unwinding reel. Through the forward and reverse rotation of the winding motor, the automatic unfolding and winding of the sunshade curtain 3 is realized, and the convenience of use is improved. The sunshade 3 can be automatically rolled back onto the outer wall of the reel when not in use, saving space in the vehicle. The elastic force of the torsion spring helps to keep the sunshade 3 in a tight state, preventing it from making noise or being damaged due to looseness during driving. The automatic unfolding and retracting function of the sunshade 3 allows passengers to adjust the light and temperature in the vehicle at any time as needed, thereby improving riding comfort.

[0100] In conjunction with the second aspect, in one implementation, 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 in the height direction of the vehicle body to form the hollow layer area 1.

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

[0102] In conjunction with the second aspect, in one implementation, 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 a front cross beam 10 via bolts 9. One end of the inner layer of glass 7 is fixed to the front cross beam 10 via glue 11; the fixed electrode 2 is fixed to the front cross beam 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 mode of the support 8, the front cross beam 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 cross beam 10 by bolts 9. One end of the inner glass 7 is glued and fixed to the front cross beam 10 by glue 11, forming a stable structural connection. The two fixed electrodes 2 are fixed to the front cross beam 10 and electrically connected to the vehicle heating control system through the conductive wire 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 wire harness three 12, and then the sunshade 3 is heated.

[0104] In combination with the second aspect, in one embodiment, the double-layer skylight device with built-in sunshade includes: a frame, the outer glass 6 and the inner 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 rod 13 is fixed to the starting end of the sunshade 3, and the two ends of the sunshade rod 13 are slidably connected in the two guide rails.

[0105] In this embodiment, the outer glass 6 and the inner glass 7 are fixed on the frame to form a stable double-layer canopy structure. At the same time, two guide rails are fixed on the frame. The two guide rails extend along the length direction of the vehicle body and are spaced apart along the width direction of the vehicle body, providing a path for the sliding of the sunshade 3. A sunshade pull rod 13 is fixed at 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. In this way, the sunshade pull rod 13 can slide in the guide rail, thereby driving the sunshade 3 to unfold or retract along the length direction of the guide rail. When sunshade is needed, the sunshade pull rod 13 can be pushed manually or electrically to slide along the guide rail, thereby driving the sunshade 3 to unfold, block the space between the outer glass 6 and the inner glass 7, and realize the sunshade function. When sunshade is not needed, the sunshade pull rod 13 can be pushed in the opposite direction to retract the sunshade 3. Through the unfolding and retracting of the sunshade 3, the light and temperature in the car can be flexibly controlled to improve the riding comfort. Especially when the sun is strong or the privacy in the car needs to be protected, the sunshade effect of the sunshade 3 is particularly obvious. When the sunshade 3 is folded, it takes up little space and will not affect other functions and usage space in the car. At the same time, the double-layer skylight structure also makes full use of the space on the roof, providing passengers with a more spacious and comfortable riding environment. Whether it is manual or electric, the sliding of the sunshade pull rod 13 is very smooth, making the unfolding 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, the embodiments of the present application provide a method for treating water mist condensation of a canopy using a double-layer canopy device with a built-in sunshade curtain as described in some of the above embodiments, which comprises 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 unfolded state, the rolling curtain 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 realizes intelligent monitoring and response to the humidity of the hollow layer area 1 of the vehicle, and monitors the humidity parameters of the hollow layer area 1 in real time through the humidity sensor, ensuring the immediate perception of changes in the in-vehicle environment. When the humidity parameter in the hollow layer area 1 is lower than the set threshold and the sunshade 3 is not fully unfolded, the system automatically controls the unwinding of the rolling device. This operation helps to heat the entire sunshade 3 and the hollow layer area 1 by unfolding the sunshade 3 when the 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 starts heating for a set time. This helps to quickly increase the temperature of the hollow layer area 1, thereby removing moisture or preventing fogging, and keeping the sunshade 3 dry as a whole. By automatically adjusting the sunshade heating function, the system helps to maintain the stability and comfort of the in-vehicle environment. At the same time, it also improves driving safety. The heating function is activated only under specific conditions (humidity is lower than the threshold and the sunshade is not fully unfolded), which helps to avoid unnecessary energy consumption and achieve energy efficiency optimization. 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 implementation, 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 of the hollow layer 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 is lower than the set threshold. This step ensures that when the humidity of the hollow layer is too low, the system can respond quickly and improve the interior environment by adjusting and heating the sunshade 3. The unwinding of the sunshade 3 not only helps to adjust the light inside the car, but the activation of the heater 5 directly increases the temperature of the hollow layer area 1, which helps to remove moisture or prevent fogging. Step S300 turns on the external circulation of the vehicle to evaporate the water mist in the hollow layer area 1 into gas and discharge it outside the vehicle. This operation helps to further reduce the humidity of the hollow layer area 1 and prevent moisture from accumulating in the car. By comprehensively adjusting humidity, temperature and light, these two steps together create a more comfortable and pleasant interior environment for the driver and passengers. Clear windows and appropriate humidity in the car also improve driving safety and overall experience. The system activates the heater 5 and the external circulation only when needed, which helps to reduce unnecessary energy consumption. By effectively managing the humidity in the car, it is also possible to reduce mold growth and odor problems caused by excessive humidity, thereby improving the quality of the air in the car. In short, it provides the driver and passengers with the best in-car environment experience.

[0113] In conjunction with the third aspect, in one implementation, 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.
