Description

Double-layered canopy system with built-in sunshade, vehicle and canopy water mist treatment method Technical Field

[0001] This application relates to the field of vehicle roof awnings, specifically to a double-layered awning device with a built-in sunshade, a vehicle, and a method for treating water mist from the awning. Background Technology

[0002] Car sunroofs primarily serve functions such as sunshade, ventilation, and increasing the perceived space. Specifically, they effectively block direct sunlight, lower interior temperature, and reduce UV damage to interior trim and seats. Some sunroofs use breathable materials, allowing airflow and improving cabin air circulation. Their transparency makes the interior appear more spacious and bright, and some sunroofs even offer adjustable transparency. Some sunroofs incorporate speakers and audio systems, providing entertainment features such as music playback. As an exterior accessory, they add a stylish element to the car and meet individual preferences. In short, a car sunroof is a practical automotive accessory that significantly enhances the driving and passenger experience.

[0003] In related technologies, the current double-layered canopy with built-in sunshades has a hollow layer between the two light-transmitting layers, and the curtain fabric in the sunshade assembly is located in the hollow layer. The gap in the hollow layer is small and it is connected to the passenger cabin. When the ambient humidity is high and the temperature changes drastically, water vapor condensation is likely to occur. The condensed water droplets cannot escape from the interlayer, leading to the following complaints: the condensed fog obstructs the view, causing sensory complaints; the water droplets condensing on the sunshade mix together, which can easily cause the sunshade to smell bad over time; and the condensed water droplets freeze in low-temperature environments, causing the sunshade to malfunction or the curtain fabric to deform and be damaged.

[0054] It's important to understand that car sunroofs primarily serve functions such as sunshade, ventilation, and increasing the perceived space. Specifically, they effectively block direct sunlight, lower interior temperature, and reduce UV damage to interior trim and seats. Some sunroofs use breathable materials, allowing airflow and improving cabin air circulation. Their transparency makes the interior appear more spacious and bright, and some sunroofs even offer adjustable transparency. Some sunroofs incorporate speakers and audio systems, providing entertainment features such as music playback. As an exterior accessory, they add a stylish element to the car and meet individual preferences. In short, a car sunroof is a practical automotive accessory that significantly enhances the driving and passenger experience.

[0055] Currently, the double-layered canopy with built-in sunshades has a hollow layer between the two light-transmitting layers, and the curtain fabric in the sunshade assembly is located in the hollow layer. The gap in the hollow layer is small and it is connected to the passenger cabin. When the ambient humidity is high and the temperature changes drastically, water vapor can easily condense. The condensed water droplets cannot escape from the interlayer, leading to the following complaints: the condensed fog obstructs the view, causing sensory complaints; the water droplets mixed together on the sunshade can easily cause the sunshade to smell bad over time; and the condensed water droplets freeze in low-temperature environments, causing the sunshade to malfunction or the curtain fabric to deform and be damaged.

[0056] This application provides a double-layer canopy device with a built-in sunshade, a vehicle, and a method for treating water mist within the canopy. A heater connected to a power source dries and heats the unfolded sunshade and the hollow layer area, turning the water mist into gaseous water vapor. The vapor is then carried away by airflow, achieving a defrosting and defogging effect. This solves the problem of water mist condensing or even freezing in the middle layer area of ​​traditional double-layer canopies, leading to sunshade rot, foul odor, malfunction, and damage.

[0057] In a first aspect, as shown in Figures 1 and 2, embodiments of this application provide a double-layer canopy device with a built-in sunshade curtain, comprising: a double-layer canopy body, the double-layer canopy body including a hollow layer region 1, the hollow layer region 1 being provided with a fixed electrode 2; a sunshade curtain 3, the sunshade curtain 3 being disposed within the hollow layer region 1, the sunshade curtain 3 being fixed with a movable electrode 4; a heater 5, the heater 5 being laid on the sunshade curtain 3, and the heater 5 being electrically connected to the movable electrode 4; and a roller blind device, the roller blind device being connected to the sunshade curtain 3, the roller blind device being configured to drive the sunshade curtain 3 to unroll, so that the movable electrode 4 is inserted into the fixed electrode 2.

[0058] In this embodiment, the roller shutter device enables the unrolling or retracting of the sunshade curtain 3, ensuring normal use. When water mist is detected in the hollow layer area 1, the roller shutter device can be used to unroll and lay out the sunshade curtain 3 until the movable electrode 4 on the sunshade curtain 3 inserts into the corresponding fixed electrode 2, allowing the heater 5 to be connected to the power supply for drying and heating. This dries and heats the laid-out sunshade curtain 3 and the hollow layer area 1, turning the water mist into gaseous water vapor. Subsequently, the water vapor is carried away by airflow, achieving a defrosting and defogging effect. This solves the problem of water mist condensation or even freezing in the middle layer area of ​​the double-layer canopy, which leads to the sunshade curtain rotting, smelling bad, becoming inoperable, and being damaged.

[0059] In conjunction with the first aspect, in one embodiment, as shown in Figures 1 and 2, the fixed electrode 2 has a slot 201 on the side facing the sunshade 3, and the two inner sidewalls of the slot 201 have limiting grooves. The movable electrode 4 has protrusions on opposite sides that are adapted to the limiting grooves.

[0060] In this embodiment, as shown in Figure 1, the fixed electrode 2 can be rectangular and located at the front end of the hollow layer region 1. The fixed electrode 2 has a slot 201 on its rear-facing sidewall, and limiting grooves can be formed on the two opposite inner sidewalls of the slot 201. The movable electrode 4 has protrusions on both opposite sides that are 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. This can enhance the contact stability between the movable electrode 4 and the fixed electrode 2, and prevent intermittent connection or disconnection between the movable electrode 4 and the fixed electrode 2 when the vehicle is bumpy, which would affect the normal operation of the heater 5.

[0061] In conjunction with the first aspect, in one embodiment, as shown in FIG2, there are two fixed electrodes 2 and two movable electrodes 4, which are spaced apart along the width direction of the vehicle body; there are multiple heaters 5, which are spaced apart within the sunshade 3 along the length direction of the vehicle body; the multiple heaters 5 are connected in parallel, and the first parallel end of the multiple heaters 5 is electrically connected to the first movable electrode 4, and its second parallel end is electrically connected to the second movable electrode 4.

[0062] Two fixed electrodes 2 are fixed at the front end of the hollow layer area 1. The two fixed electrodes 2 are distributed at intervals along the width direction of the vehicle body, that is, distributed at intervals in the left and right directions as shown in Figure 2. The sunshade 3 is set in the hollow layer area 1. Two movable electrodes 4 are fixed at the front end of the sunshade 3. The two movable electrodes 4 are also distributed at intervals in the left and right directions and correspond one-to-one with the two fixed electrodes 2. The heater 5 is laid on the sunshade 3. The roller shutter device can drive the sunshade 3 to unroll and roll up or roll up.

[0063] In this embodiment, there are multiple heaters 5, which are spaced apart along the front-to-back direction and connected in parallel. The first parallel connection ends of the multiple heaters 5 form a first busbar, and the second parallel connection ends form a second busbar. The first and second busbars are spaced apart along the left-to-right direction and are electrically connected to the corresponding movable electrodes 4. This enables uniform heating of the sunshade curtain 3, ensuring stable overall heating and preventing the risk of fire due to concentrated local heating.

[0064] In conjunction with the first aspect, in one embodiment, there are two fixed electrodes 2 and two movable electrodes 4, 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, which is installed inside the sunshade 3, and a first end of the PTC heating element is electrically connected to a conductive wire harness one, and a second end of the PTC heating element is electrically connected to a conductive wire harness two; the first conductive wire harness is fixed to the first movable electrode 4, and the second conductive wire harness is fixed to the second movable electrode 4.

[0065] In this embodiment, wire harness one forms the first busbar, and conductive wire harness two forms the second busbar. Wire harness one and conductive wire harness two are spaced apart in the left-right direction, and their length directions are spaced apart in the front-back direction. They are laid on the sunshade curtain 3 for easy unwinding and rewinding along with the sunshade curtain 3. The PTC heating element, also called a PTC heater, 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, making it an automatic temperature-controlled, energy-saving electric heater. Its outstanding feature is its safety performance; under any application, it will not produce the surface "reddening" phenomenon seen in electric heating tube heaters, thus avoiding safety hazards such as burns and fires.

[0066] In conjunction with the first aspect, in one embodiment, there are two fixed electrodes 2 and two movable electrodes 4, 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, which are installed inside the sunshade 3, and the first end of the plurality of heating wires is electrically connected to a conductive wire harness one, and the second end of the conductive wire harness is electrically connected to a conductive wire harness two; the conductive wire harness one is fixed to the first movable electrode 4, and the conductive wire harness two is fixed to the second movable electrode 4.

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

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

[0069] In this embodiment, by extending the heating wires in an S-shape or a spiral disc shape, the number of heating wires can be reduced while still ensuring a uniform heating effect for the sunshade curtain 3.

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

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

[0072] In conjunction with the first aspect, in one embodiment, the roller blind device includes: a roll-up shaft, the roll-up shaft being provided with a torsion spring, the sunshade 3 being wound around the outer wall of the roll-up shaft, the elastic force of the torsion spring tending to pull the sunshade 3 to roll up; a roll-up motor, the output end of the roll-up motor being fixed with a winding wheel, the winding wheel and the roll-up shaft being spaced apart along the length direction of the vehicle body; and a winding cord, one end of the winding cord being connected to the starting end of the sunshade 3, and the other end being connected to the winding wheel.

[0073] In this embodiment, the working principle of the roller blind device mainly relies on the synergistic effect of the torsion spring, the winding motor, and the winding cord. Specifically, in the initial state: the sunshade 3 is wound around the outer wall of the unwinding shaft, and the torsion spring is in a certain stored state, its elastic force tending to pull the sunshade 3 to roll up, that is, to keep the sunshade 3 automatically rolled up when not subjected to external force. When it is necessary to unfold the sunshade 3, the winding motor starts, and the winding wheel fixed at its output end begins to rotate. Since 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 wheel, the rotation of the winding wheel will pull the winding cord, thereby driving the sunshade 3 to unfold from the unwinding shaft. When it is necessary to roll up the sunshade 3, the winding motor rotates in the opposite direction, and the winding wheel rotates in the opposite direction accordingly, releasing the winding cord. At this time, the elastic force of the torsion spring begins to appear, pulling the sunshade 3 back to the outer wall of the unwinding shaft. By rotating the winding motor in both directions, the automatic unfolding and rolling up of the sunshade 3 is achieved, improving the convenience of use. When not in use, the sunshade 3 can automatically roll back onto the outer wall of the roller, saving interior space. The torsion spring helps maintain the sunshade 3's tautness, preventing noise or damage caused by loosening during driving. The automatic unfolding and rolling function of the sunshade 3 allows passengers to adjust the light and temperature inside the vehicle as needed, improving ride comfort.

[0074] In conjunction with the first aspect, in one embodiment, as shown in FIG1, the double-layer canopy body includes an outer glass layer 6 and an inner glass layer 7, wherein the outer glass layer 6 and the inner glass layer 7 are arranged in parallel and are spaced apart along the vehicle height direction to form the hollow layer region 1.

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

[0076] In conjunction with the first aspect, in one embodiment, as shown in Figures 1 and 2, a support 8 is fixed to the inner side of the outer glass 6 near the front of the vehicle, and the support 8 is fixed to the front crossbeam 10 by bolts 9. One end of the inner glass 7 is fixed to the front crossbeam 10 by 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 wire harness 3 12.

[0077] In this embodiment, the working principle mainly involves the interaction and connection of the support 8, the front crossbeam 10, the inner glass 7, and the fixed electrodes 2. The support 8 is fixed to the inner side of the outer glass 6 near the front of the vehicle, and the support 8 is firmly fixed to the front crossbeam 10 by bolts 9. One end of the inner glass 7 is glued to the front crossbeam 10, forming a stable structural connection. The two fixed electrodes 2 are fixed to the front crossbeam 10 and electrically connected to the vehicle's heating control system via conductive wiring harness 3 12. In this way, the fixed electrodes 2 can receive electrical signals and control commands from the vehicle's heating control system.

[0078] When the vehicle's heating control system issues a heating command, the electrical signal is transmitted to the fixed electrode 2 through the conductive wire harness 312, thereby heating the sunshade 3.

[0079] In conjunction with the first aspect, in one embodiment, the double-layer canopy 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; the starting end of the sunshade 3 is fixed with a sunshade rod 13, and the two ends of the sunshade rod 13 are slidably connected to the two guide rails.

[0080] In this embodiment, both the outer glass layer 6 and the inner glass layer 7 are fixed to the frame, forming a stable double-layer sunroof structure. Simultaneously, two guide rails are fixed to the frame, extending along the length of the vehicle body and spaced apart along its width, providing a path for the sliding of the sunshade 3. A sunshade rod 13 is fixed to the beginning of the sunshade 3, and its two ends are slidably connected to the two guide rails. Thus, the sunshade rod 13 can slide within the guide rails, thereby causing the sunshade 3 to unfold or retract along the length of the guide rails. When sunshade is needed, the sunshade rod 13 can be pushed manually or electrically to slide along the guide rails, thereby unfolding the sunshade 3 and blocking the space between the outer glass layer 6 and the inner glass layer 7, achieving the sunshade function. When sunshade is not needed, the sunshade rod 13 can be pushed in the opposite direction to retract the sunshade 3. By unfolding and retracting the sunshade 3, the light and temperature inside the vehicle can be flexibly controlled, improving passenger comfort. Especially in situations with strong sunlight or when privacy is crucial, the sunshade 3's sun-shading effect is particularly noticeable. When retracted, the sunshade 3 takes up minimal space and does not affect other functions or usable space within the vehicle. Simultaneously, the double-layered sunroof structure makes full use of 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 unfolding and retraction of the sunshade 3 extremely simple and convenient. This also enhances the passenger's user experience and satisfaction.

[0081] Secondly, as shown in Figures 1 and 2, embodiments of this application provide a vehicle including a double-layered sunshade device with a built-in sunshade as described in some of the above embodiments. The double-layered sunshade device includes: a double-layered sunshade body, the double-layered sunshade body including a hollow layer region 1, the hollow layer region 1 being provided with a fixed electrode 2; a sunshade 3, the sunshade 3 being disposed within the hollow layer region 1, the sunshade 3 being fixed with a movable electrode 4; a heater 5, the heater 5 being laid on the sunshade 3, and the heater 5 being electrically connected to the movable electrode 4; and a roller blind device, the roller blind device being connected to the sunshade 3, the roller blind device being configured to drive the sunshade 3 to unroll, so that the movable electrode 4 is inserted into the fixed electrode 2.

[0082] Specifically, the roller shutter device enables the unrolling or retracting of the sunshade curtain 3 to ensure normal use. When water mist is detected in the hollow layer area 1, the roller shutter device can be used to unroll and lay out the sunshade curtain 3 until the movable electrode 4 on the sunshade curtain 3 inserts into the corresponding fixed electrode 2, allowing the heater 5 to be connected to the power supply for drying and heating. This dries and heats the laid-out sunshade curtain 3 and the hollow layer area 1, turning the water mist into gaseous water vapor. Subsequently, the water vapor is carried away by airflow, achieving a defrosting and defogging effect. This solves the problem of water mist condensation or even freezing in the middle layer area of ​​the double-layer canopy, which leads to the sunshade curtain rotting, smelling bad, becoming inoperable, and being damaged.

[0083] In conjunction with the second aspect, in one embodiment, the vehicle heating control system includes: a power supply; a controller electrically connected to the power supply; a humidity sensor installed in the hollow layer region 1 and electrically connected to the controller; and a skylight heating switch electrically connected to the controller and the two fixed electrodes 2.

[0084] In this embodiment, the power supply provides the necessary electrical energy for the entire heating control system. A humidity sensor is installed in the hollow layer area 1 to detect the humidity in that area in real time. The humidity sensor is electrically connected to the controller, transmitting the detected humidity signal to the controller. After receiving the humidity signal from the humidity sensor, the controller processes it and determines whether the heating function needs to be activated. For example, when the humidity reaches a certain threshold, the controller may determine that heating is needed to remove moisture or prevent fogging. When the sunshade heating switch is turned on and the controller determines that heating is needed, the controller sends a heating command to the two fixed electrodes 2. After receiving the command, the fixed electrodes 2 connect the heater 5 to the circuit for 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. By heating the sunshade 3, fog or frost can be effectively removed, improving the transparency of the windows and thus enhancing driving safety. In cold or damp weather, the heating function can raise the temperature inside the vehicle, providing a more comfortable riding environment for passengers. The combined use of the humidity sensor and the sunshade heating switch enables intelligent control of the heating function. The system can automatically adjust the heating status according to the actual humidity and passenger needs, improving ease of use and energy efficiency. The heating function can also effectively prevent condensation and corrosion in the hollow area 1, extending the service life of the sunshade 3.

[0085] In conjunction with the second aspect, in one embodiment, a temperature sensor can also replace the humidity 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 practical applications, different continuous heating times can be adopted according to customer needs.

[0086] In conjunction with the second aspect, in one embodiment, as shown in Figures 1 and 2, the fixed electrode 2 has a slot 201 on the side facing the sunshade 3, and the two inner sidewalls of the slot 201 have limiting grooves. The movable electrode 4 has protrusions on opposite sides that are adapted to the limiting grooves.

[0087] In this embodiment, as shown in Figure 1, the fixed electrode 2 can be rectangular and located at the front end of the hollow layer region 1. The fixed electrode 2 has a slot 201 on its rear-facing sidewall, and limiting grooves can be formed on the two opposite inner sidewalls of the slot 201. The movable electrode 4 has protrusions on both opposite sides that are 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. This can enhance the contact stability between the movable electrode 4 and the fixed electrode 2, and prevent intermittent connection or disconnection between the movable electrode 4 and the fixed electrode 2 when the vehicle is bumpy, which would affect the normal operation of the heater 5.

[0088] In conjunction with the second aspect, in one embodiment, as shown in FIG2, there are two fixed electrodes 2 and two movable electrodes 4, which are spaced apart along the width direction of the vehicle body; there are multiple heaters 5, which are spaced apart within the sunshade 3 along the length direction of the vehicle body; the multiple heaters 5 are connected in parallel, and the first parallel connection end of the multiple heaters 5 is electrically connected to the first movable electrode 4, and its second parallel connection end is electrically connected to the second movable electrode 4.

[0089] Two fixed electrodes 2 are fixed at the front end of the hollow layer area 1. The two fixed electrodes 2 are distributed at intervals along the width direction of the vehicle body, that is, distributed at intervals in the left and right directions as shown in Figure 2. The sunshade 3 is set in the hollow layer area 1. Two movable electrodes 4 are fixed at the front end of the sunshade 3. The two movable electrodes 4 are also distributed at intervals in the left and right directions and correspond one-to-one with the two fixed electrodes 2. The heater 5 is laid on the sunshade 3. The roller shutter device can drive the sunshade 3 to unroll and roll up or roll up.

[0090] In this embodiment, there are multiple heaters 5, which are spaced apart along the front-to-back direction and connected in parallel. The first parallel connection ends of the multiple heaters 5 form a first busbar, and the second parallel connection ends form a second busbar. The first and second busbars are spaced apart along the left-to-right direction and are electrically connected to the corresponding movable electrodes 4. This enables uniform heating of the sunshade curtain 3, ensuring stable overall heating and preventing the risk of fire due to concentrated local heating.

[0091] In conjunction with the second aspect, in one embodiment, there are two fixed electrodes 2 and two movable electrodes 4, which are spaced apart along the width of the vehicle body; the heater 5 includes a PTC heating element, which is installed inside the sunshade 3, and a first end of the PTC heating element is electrically connected to a conductive wire harness one, and a second end of the PTC heating element is electrically connected to a conductive wire harness two; the first conductive wire harness is fixed to the first movable electrode 4, and the second conductive wire harness is fixed to the second movable electrode 4.

[0092] In this embodiment, wire harness one forms the first busbar, and conductive wire harness two forms the second busbar. Wire harness one and conductive wire harness two are spaced apart in the left-right direction, and their length directions are spaced apart in the front-back direction. They are laid on the sunshade curtain 3 for easy unwinding and rewinding along with the sunshade curtain 3. The PTC heating element, also called a PTC heater, 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, making it an automatic temperature-controlled, energy-saving electric heater. Its outstanding feature is its safety performance; under any application, it will not produce the surface "reddening" phenomenon seen in electric heating tube heaters, thus avoiding safety hazards such as burns and fires.

[0093] In conjunction with the second aspect, in one embodiment, there are two fixed electrodes 2 and two movable electrodes 4, 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, which are installed inside the sunshade 3, and the first end of the plurality of heating wires is electrically connected to a conductive wire harness one, and the second end is electrically connected to a conductive wire harness two; the conductive wire harness one is fixed to the first movable electrode 4, and the conductive wire harness two is fixed to the second movable electrode 4.

[0094] In this embodiment, the heater 5 can also be heated by a heating wire or a heating tube, and the heating temperature of the heating wire or heating tube can be controlled.

[0095] In conjunction with the second aspect, in one embodiment, the extension path of the heating wire is S-shaped or spiral disk-shaped.

[0096] In this embodiment, by extending the heating wires in an S-shape or a spiral disc shape, the number of heating wires can be reduced while still ensuring a uniform heating effect for the sunshade curtain 3.

[0097] In conjunction with the second aspect, in one embodiment, the sunshade 3 includes an inner layer fabric and an outer layer fabric fixed to the inner layer fabric; the heater 5 is laid between the inner layer fabric and the outer layer fabric or on the side of the inner layer fabric away from the outer layer fabric.

[0098] In this embodiment, the curtain fabric of the sunshade curtain 3 includes an inner layer and an outer layer. A heater 5 is arranged in the inner layer, and the outer layer can be made of antibacterial and waterproof fibers.

[0099] In conjunction with the second aspect, in one embodiment, the roller blind device includes: a roll-up shaft, the roll-up shaft being provided with a torsion spring, the sunshade 3 being wound around the outer wall of the roll-up shaft, the elastic force of the torsion spring tending to pull the sunshade 3 to roll up; a roll-up motor, the output end of the roll-up motor being fixed with a winding wheel, the winding wheel and the roll-up shaft being spaced apart along the length direction of the vehicle body; and a winding cord, one end of the winding cord being connected to the starting end of the sunshade 3, and the other end being connected to the winding wheel.

[0100] In this embodiment, the working principle of the roller blind device mainly relies on the synergistic effect of the torsion spring, the winding motor, and the winding cord. Specifically, in the initial state: the sunshade 3 is wound around the outer wall of the unwinding shaft, and the torsion spring is in a certain stored state, its elastic force tending to pull the sunshade 3 to roll up, that is, to keep the sunshade 3 automatically rolled up when not subjected to external force. When it is necessary to unfold the sunshade 3, the winding motor starts, and the winding wheel fixed at its output end begins to rotate. Since 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 wheel, the rotation of the winding wheel will pull the winding cord, thereby driving the sunshade 3 to unfold from the unwinding shaft. When it is necessary to roll up the sunshade 3, the winding motor rotates in the opposite direction, and the winding wheel rotates in the opposite direction accordingly, releasing the winding cord. At this time, the elastic force of the torsion spring begins to appear, pulling the sunshade 3 back to the outer wall of the unwinding shaft. By rotating the winding motor in both directions, the automatic unfolding and rolling up of the sunshade 3 is achieved, improving the convenience of use. When not in use, the sunshade 3 can automatically roll back onto the outer wall of the roller, saving interior space. The torsion spring helps maintain the sunshade 3's tautness, preventing noise or damage caused by loosening during driving. The automatic unfolding and rolling function of the sunshade 3 allows passengers to adjust the light and temperature inside the vehicle as needed, improving ride comfort.

[0101] In conjunction with the second aspect, in one embodiment, as shown in Figure 1, the double-layered canopy body includes an outer glass layer 6 and an inner glass layer 7, wherein the outer glass layer 6 and the inner glass layer 7 are arranged in parallel and are spaced apart along the vehicle height direction to form the hollow layer region 1.

[0102] In this embodiment, the outer glass 6 can be laminated glass or single-layer glass; the inner glass 7 is tempered glass; the outer glass 6 in Figure 1 is laminated glass.

[0103] In conjunction with the second aspect, in one embodiment, as shown in Figures 1 and 2, a support 8 is fixed to the inner side of the outer glass 6 near the front of the vehicle, and the support 8 is fixed to the front crossbeam 10 by bolts 9. One end of the inner glass 7 is fixed to the front crossbeam 10 by 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 wire harness 3 12.

[0104] In this embodiment, the working principle mainly involves the interaction and connection of the support 8, the front crossbeam 10, the inner glass 7, and the fixed electrodes 2. The support 8 is fixed to the inner side of the outer glass 6 near the front of the vehicle, and the support 8 is firmly fixed to the front crossbeam 10 by bolts 9. One end of the inner glass 7 is glued to the front crossbeam 10, forming a stable structural connection. The two fixed electrodes 2 are fixed to the front crossbeam 10 and electrically connected to the vehicle's heating control system via conductive wiring harness 3 12. In this way, the fixed electrodes 2 can receive electrical signals and control commands from the vehicle's heating control system.

[0105] When the vehicle's heating control system issues a heating command, the electrical signal is transmitted to the fixed electrode 2 through the conductive wire harness 312, thereby heating the sunshade 3.

[0106] In conjunction with the second aspect, in one embodiment, the double-layered canopy device with built-in sunshade includes:

[0107] The 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; the starting end of the sunshade 3 is fixed with a sunshade rod 13, and the two ends of the sunshade rod 13 are slidably connected to the two guide rails.

[0108] In this embodiment, both the outer glass layer 6 and the inner glass layer 7 are fixed to the frame, forming a stable double-layer sunroof structure. Simultaneously, two guide rails are fixed to the frame, extending along the length of the vehicle body and spaced apart along its width, providing a path for the sliding of the sunshade 3. A sunshade rod 13 is fixed to the beginning of the sunshade 3, and its two ends are slidably connected to the two guide rails. Thus, the sunshade rod 13 can slide within the guide rails, thereby causing the sunshade 3 to unfold or retract along the length of the guide rails. When sunshade is needed, the sunshade rod 13 can be pushed manually or electrically to slide along the guide rails, thereby unfolding the sunshade 3 and blocking the space between the outer glass layer 6 and the inner glass layer 7, achieving the sunshade function. When sunshade is not needed, the sunshade rod 13 can be pushed in the opposite direction to retract the sunshade 3. By unfolding and retracting the sunshade 3, the light and temperature inside the vehicle can be flexibly controlled, improving passenger comfort. Especially in situations with strong sunlight or when privacy is crucial, the sunshade 3's sun-shading effect is particularly noticeable. When retracted, the sunshade 3 takes up minimal space and does not affect other functions or usable space within the vehicle. Simultaneously, the double-layered sunroof structure makes full use of 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 unfolding and retraction of the sunshade 3 extremely simple and convenient. This also enhances the passenger's user experience and satisfaction.

[0109] Thirdly, embodiments of this application provide a method for treating water mist condensation in 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:

[0110] S100: Acquire humidity parameters within the hollow layer region 1 monitored by the humidity sensor;

[0111] S200: If the humidity parameter in the hollow layer area 1 is lower than the set threshold and the sunshade curtain 3 is not fully unfolded, control the roller shutter device to unroll 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.

[0112] In this embodiment, the combination of steps S100 and S200 enables intelligent monitoring and response to the humidity of the vehicle's hollow layer area 1. A humidity sensor monitors the humidity parameters of the hollow layer area 1 in real time, ensuring immediate awareness of changes in the in-vehicle environment. When the humidity parameter in the hollow layer area 1 is below a set threshold and the sunshade 3 is not fully extended, the system automatically controls the roller shutter device to unroll. This operation helps to heat the entire sunshade 3 and the hollow layer area 1 when humidity is low. After the active 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 to quickly raise the temperature of the hollow layer area 1, thereby removing moisture or preventing fogging and keeping the sunshade 3 dry. By automatically adjusting the sunshade heating function, the system helps maintain the stability and comfort of the in-vehicle environment, while also improving driving safety. Activating the heating function only under specific conditions (humidity below the threshold and the sunshade not fully extended) helps avoid unnecessary energy consumption and optimizes energy efficiency. In summary, this control logic not only improves driving safety and comfort, but also optimizes vehicle energy efficiency through intelligent monitoring and response mechanisms.

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

[0114] S300: Controls the vehicle to activate the external air circulation, allowing the water mist to dry into gaseous water vapor and be expelled outside the vehicle.

[0115] In this embodiment, step S200 monitors the humidity of the hollow layer area 1 in real time and automatically triggers a series of actions when the humidity falls below a set threshold, including unrolling the sunshade 3 and activating the heater 5. This step ensures that the system can respond quickly when the humidity in the hollow layer is too low, improving the in-vehicle environment through the adjustment and heating of the sunshade 3. Unrolling the sunshade 3 not only helps regulate the light inside the vehicle, but the activation of the heater 5 directly increases the temperature of the hollow layer area 1, helping to remove moisture or prevent fogging. Step S300 activates the vehicle's external air circulation, evaporating the water mist in the hollow layer area 1 into gas and expelling it outside the vehicle. This operation helps to further reduce the humidity in the hollow layer area 1 and prevent moisture from accumulating inside the vehicle. By comprehensively adjusting humidity, temperature, and light, these two steps together create a more comfortable and pleasant in-vehicle environment for the driver and passengers. Clear windows and suitable in-vehicle humidity also improve driving safety and the overall experience. The system only activates the heater 5 and external air circulation when needed, which helps reduce unnecessary energy consumption. Effective management of in-vehicle humidity can reduce mold growth and odor problems caused by excessive humidity, thereby improving in-vehicle air quality. In conclusion, this provides the best in-vehicle environment experience for both driver and passengers.

[0116] In conjunction with the third aspect, in one implementation, after S200, the following steps are included:

[0117] S300: Controls the vehicle to open the windows, allowing water mist to dry into gaseous water vapor and be expelled outside the vehicle.

[0118] Of course, in some embodiments, the windows can also be opened to expel the vapors from the water mist outside the vehicle.
