Description

Technical Field

[0001] This invention mainly relates to the technical field of automotive parts, specifically an intelligent automotive solar shading and cooling system based on airflow circulation. Background Technology

[0002] Car sunshades are sun-shading devices installed on car windows or windshields, mainly composed of flexible fabric and a supporting structure. Their core function is to physically block sunlight from directly entering the car interior, reducing heat buildup and lowering the interior temperature, while also protecting dashboard, seats, and other interior components from UV damage. Depending on the structure, common types include manually folding, automatically retractable roller, and electrically driven rail types. The fabric is typically made of reflective, heat-insulating materials or composite materials integrating solar photovoltaic functions, and they are widely used for sun protection when the vehicle is parked.

[0003] Existing automotive sunshade products generally suffer from the following shortcomings: Traditional sunshades can only physically block light from entering the vehicle, failing to actively dissipate heat already accumulated inside, resulting in extremely limited cooling effects. The dashboard and overall interior temperature remain high even after prolonged exposure to direct sunlight. Furthermore, most existing sunshade products rely on the vehicle's own battery for power or are designed without any power source. They lack continuous power support after the vehicle is parked and the engine is off, making automatic operation unrestricted for extended periods. Even products equipped with fans or ventilation systems are limited by the vehicle's battery capacity, easily leading to battery depletion with prolonged use. Additionally, installation typically requires modifications to the vehicle's existing wiring, posing safety hazards and compatibility issues with different vehicle models. In addition, existing sunshade products generally lack intelligent sensing and control capabilities, and cannot automatically respond to changes in the actual vehicle status, ambient light, and interior temperature. They require manual operation to unfold or retract, resulting in poor ease of use. They cannot automatically complete the cooling task while the owner is away from the vehicle, nor are they equipped with an automatic emergency retraction mechanism when the vehicle is started, posing a potential safety hazard. Furthermore, the lack of multi-sensor collaborative judgment makes the system prone to invalid startup due to a single temperature signal, resulting in unnecessary energy waste. Summary of the Invention

[0004] Therefore, the purpose of this invention is to provide an intelligent automotive solar shading and cooling system based on airflow circulation to solve the technical problems mentioned in the background art.

[0005] A smart car solar shading and cooling system based on airflow circulation includes a main box, a sunshade curtain retraction assembly inside the main box, an air inlet assembly at one end of the main box, and an intelligent control assembly on one side of the air inlet assembly inside the main box. Guide components are provided on both sides of the top of the main box; An exhaust system is provided above the main body box; Preferably, the sunshade curtain retraction assembly includes a roller shutter shaft, a photovoltaic sunshade curtain, a driven shaft, a driven gear, a driving gear, and a drive motor. The main body box is equipped with a roller shutter shaft, and the photovoltaic sunshade curtain is wound around the outer wall of the roller shutter shaft. A driven shaft is fixedly installed inside the roller shutter shaft. A driven gear is fixedly installed on the outer side of one end of the driven shaft. A driving gear meshes with one side of the driven gear, and a drive motor is fixedly installed at the end of the driving gear.

[0006] Preferably, the air inlet assembly includes an air inlet, a first axial flow fan, a flow guide box, and a flow guide groove. An air inlet is installed at one end of the main body box, and a first axial flow fan is fixedly installed inside the main body box at the end of the air inlet. A flow guide box is installed on one side of the main body box, and multiple flow guide grooves are formed on the surface of the flow guide box.

[0007] Preferably, the intelligent control component includes a vibration sensor, a light sensor, an internal temperature sensor, an external temperature sensor, a battery, and a control module. The main body box surface is provided with a vibration sensor, a light sensor, an internal temperature sensor, an external temperature sensor, and a battery on the side of the air inlet component. A control module is installed on the other side surface of the main box.

[0008] Preferably, the guiding assembly includes a guide rail, a guide groove, a synchronous pulley, and a synchronous belt. Guide rails are fixedly installed on both sides of the top of the main body box, and guide grooves are opened on opposite sides of the two guide rails. Synchronous pulleys are provided inside the two guide grooves and at both ends of the driven shaft. The synchronous pulley inside the guide groove is connected to the synchronous pulley at one end of the driven shaft via a synchronous belt.

[0009] Preferably, the exhaust assembly includes an exhaust duct, a receiving port, a second axial flow fan, and an exhaust outlet. The exhaust duct is provided above the main body box, and multiple receiving ports are provided at the bottom of the exhaust duct. The second axial flow fan is fixedly installed at one end inside the exhaust duct, and an exhaust outlet is fixedly installed at one end outside the exhaust duct.

[0010] Preferably, the photovoltaic sunshade curtain is fixedly connected to sliding rods at both ends, and the two sliding rods are respectively connected to opposite synchronous belts.

[0011] Preferably, the photovoltaic sunshade curtain has multiple airflow channels inside, and the top of each of the multiple airflow channels corresponds to the receiving port at the bottom of the exhaust channel.

[0012] Preferably, the drive motor drives the driven shaft to rotate through the meshing transmission of the driving gear and the driven gear, thereby driving the synchronous belt to run.

[0013] Preferably, the outlets of the plurality of guide channels all face the surface of the vehicle dashboard.

[0014] In summary, the present invention has the following main beneficial effects: 1. Through the coordinated operation of the air intake and exhaust components, a complete directional airflow circulation path is established, starting from the bottom of the dashboard, rising through the interior space, and finally being exhausted from the roof. The first axial fan draws in relatively cool fresh air from outside, which is then evenly distributed and precisely guided to the hottest surface of the dashboard by multiple guide slots on the surface of the air guide box. The cold air absorbs heat as it flows over the dashboard and rises naturally. The exhaust component exhausts the rising hot air from the sides or other areas. By utilizing the physical property of hot air rising naturally, combined with the dual effects of forced air supply and forced exhaust, the hot air inside the vehicle is continuously replaced and exhausted, which can significantly reduce the overall temperature inside the vehicle in a short period of time. This effectively avoids the shortcomings of traditional sunshades, which can only block light but cannot actively cool the vehicle.

[0015] 2. By converting solar energy into electrical energy through photovoltaic sunshades, the system provides power to the drive motor, the first axial flow fan, the second axial flow fan, and various sensors. This achieves an independent power supply architecture that is completely independent of the vehicle's battery, without consuming the vehicle's original electrical energy reserves. The battery serves as an auxiliary energy storage unit, storing excess electrical energy when there is sufficient sunlight. This integrated photovoltaic and energy storage power supply method allows the system to operate independently for a long time without external power. During installation, there is no need to modify the vehicle's original circuitry, and it does not affect the safety and stability of the vehicle's original electrical system. At the same time, the green and environmentally friendly solar power supply mode also reduces the cost of use.

[0016] 3. Through the coordinated detection of vibration sensors, light sensors, internal temperature sensors, and external temperature sensors, the control module can perceive vehicle status, ambient light, and temperature changes in real time and automatically make intelligent decisions. When the vehicle is stationary and the interior temperature reaches the preset activation value, the system automatically deploys the sunshade and starts the fan for cooling. When the temperature drops to the target value or the light is insufficient, the sunshade automatically retracts and the fan shuts off. When the vehicle starts, an emergency retraction is immediately triggered to ensure driving safety. The entire process requires no manual intervention. Simultaneously, the coordinated judgment of the light sensor and the internal temperature sensor avoids ineffective system startup due to temperature misjudgment in rainy weather or at night, further optimizing energy utilization efficiency and enabling the system to operate stably and reliably in different usage scenarios.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0020] Please refer to the appendix carefully. Figure 1 , 23, 7, 8, 9, A smart car solar shading and cooling system based on airflow circulation includes a main body box 1. Inside the main body box 1 is a sunshade curtain retraction assembly 2. The sunshade curtain retraction assembly 2 includes a roller shutter shaft 21, a photovoltaic sunshade curtain 22, a driven shaft 23, a driven gear 24, a driving gear 25, and a drive motor 26. The roller shutter shaft 21 is located inside the main body box 1, and the photovoltaic sunshade curtain 22 is wound around its outer wall. The photovoltaic sunshade curtain 22 can be rolled up or unrolled under the rotation of the roller shutter shaft 21, thus realizing the retraction and unfolding function of the sunshade curtain. The driven shaft 23 is fixedly installed inside the roller shutter shaft 21 and is fixedly connected to the roller shutter shaft 21. When the driven shaft 23 rotates, it drives the roller shutter shaft 21 to rotate synchronously. A driven gear 24 is fixedly mounted on the outer side of one end of the driven shaft 23. A driving gear 25 meshes with one side of the driven gear 24. A drive motor 26 is fixedly mounted on the end of the driving gear 25. When the drive motor 26 operates, it drives the driven shaft 23 to rotate through the meshing transmission between the driving gear 25 and the driven gear 24, thereby driving the roller blind shaft 21 to rotate and realize the unfolding and retraction of the photovoltaic sunshade curtain 22. The gear meshing transmission method has the characteristics of precise transmission and smooth operation, which can ensure the accurate positioning of the sunshade curtain during unfolding and retraction. The photovoltaic sunshade curtain 22 has the function of converting light energy into electrical energy. In the unfolded state, it can receive sunlight and generate electrical energy to provide a power source for other electrical equipment in the system.

[0021] An air inlet assembly 3 is provided at one end of the main body box 1. The air inlet assembly 3 includes an air inlet 31, a first axial flow fan 32, a guide box 33, and a guide channel 34. The air inlet 31 is installed at one end of the main body box 1 and is used to introduce air from outside the main body box 1 into the main body box 1. The first axial flow fan 32 is fixedly installed at the end of the air inlet 31 inside the main body box 1. When the first axial flow fan 32 is running, it generates negative pressure at the air inlet 31, drawing outside air into the main body box 1 and accelerating its delivery to the subsequent airflow channel. A flow guide box 33 is installed on the side. Multiple flow guide grooves 34 are opened on the surface of the flow guide box 33. The flow guide grooves 34 are arranged at equal intervals along the length of the flow guide box 33, and the outlets of the flow guide grooves 34 all face the surface of the car dashboard. The air drawn in by the first axial flow fan 32 is distributed by the flow guide box 33 and flows out evenly from each flow guide groove 34, directly blowing onto the surface of the dashboard to cool the dashboard area. Since the dashboard is one of the areas with the highest temperature in the car after being exposed to sunlight, directing the airflow directly to this area can effectively absorb and remove the accumulated heat.

[0022] Inside the main body box 1, on one side of the air intake assembly 3, there is an intelligent control assembly 4. The intelligent control assembly 4 includes a vibration sensor 41, a light sensor 42, an internal temperature sensor 43, an external temperature sensor 44, a battery 45, and a control module 46. On the surface of the main body box 1, on one side of the air intake assembly 3, there are vibration sensors 41, light sensors 42, internal temperature sensors 43, external temperature sensors 44, and a battery 45. On the other side of the main body box 1, there is a control module 46. The vibration sensor 41 is used to detect the vibration state of the vehicle, thereby determining whether the vehicle is in a driving state or a stationary state, providing a basis for determining whether the system enters the working mode. The light sensor 42 is used to detect the light intensity outside the vehicle, to determine whether the sunlight is sufficient, so as to determine whether the photovoltaic sunshade 22 has sufficient power generation conditions. The internal temperature sensor 43 is used to detect the real-time temperature inside the vehicle, and the external temperature sensor 44 is used to detect the real-time temperature outside the vehicle. The control module 46 determines whether the threshold condition for starting cooling has been reached based on the internal and external temperature data. Battery 45 is used to store the electrical energy generated by photovoltaic sunshade 22 and to supply power to various electrical devices in the system when there is insufficient sunlight, so as to ensure that the system can continue to operate. Control module 46 is electrically connected to vibration sensor 41, light sensor 42, internal temperature sensor 43, external temperature sensor 44, battery 45, drive motor 26, first axial flow fan 32 and second axial flow fan 63 respectively. Control module 46 receives the detection signals of each sensor and controls the start, stop and operation of drive motor 26, first axial flow fan 32 and second axial flow fan 63 according to preset logic.

[0023] Please refer to the appendix carefully. Figure 1 , 2 4, 5, 6, 7, 9. Guide components 5 are provided on both sides of the top of the main body box 1. The guide components 5 include guide rails 51, guide grooves 52, synchronous pulleys 53 and synchronous belts 54. Guide rails 51 are fixedly installed on both sides of the top of the main body box 1, and guide grooves 52 are opened on the opposite side of the two guide rails 51. Synchronous pulleys 53 are provided inside the guide groove 52 and at both ends of the driven shaft 23. The synchronous pulleys 53 inside the guide groove 52 and the corresponding synchronous pulleys 53 at the ends of the driven shaft 23 are connected by a synchronous belt 54 to form a closed-loop transmission circuit. The drive motor 26 drives the driven shaft 23 to rotate through the meshing of the drive gear 25 and the driven gear 24. The synchronous pulleys 53 at both ends of the driven shaft 23 rotate accordingly. The power is transmitted to the synchronous pulleys 53 inside the guide groove 52 through the synchronous belt 54, so as to realize the synchronous operation of the synchronous belts 54 on both sides. When the synchronous belt 54 is running, it drives the photovoltaic sunshade curtain 22 connected to the synchronous belt 54 to slide smoothly along the guide groove 52, ensuring that the sunshade curtain moves synchronously on both sides during the opening and closing process, and avoiding skew or jamming.

[0024] An exhaust assembly 6 is provided above the main body box 1. The exhaust assembly 6 includes an exhaust duct 61, a receiving port 62, a second axial flow fan 63, and an exhaust port 64. The exhaust duct 61 is located above the main body box 1. Multiple receiving ports 62 are provided at the bottom of the exhaust duct 61. The second axial flow fan 63 is fixedly installed at one end inside the exhaust duct 61, and the exhaust port 64 is fixedly installed at the other end of the exhaust duct 61. When the second axial flow fan 63 is running, it generates negative pressure inside the exhaust duct 61, and draws air from outside the exhaust duct 61 into the exhaust duct 61 through the receiving port 62 and accelerates its delivery to the exhaust port 64 for discharge.

[0025] Please refer to the appendix carefully. Figure 1-9 The photovoltaic sunshade curtain 22 has sliding rods 7 fixedly connected to both ends, and each sliding rod 7 is fixedly connected to its corresponding synchronous belt 54. Multiple airflow channels 8 are provided inside the photovoltaic sunshade curtain 22, with the top of each channel 8 corresponding to the receiving port 62 at the bottom of the exhaust channel 61. When the synchronous belt 54 rotates, the sliding rods 7 slide along the guide groove 52 with the synchronous belt 54, causing the photovoltaic sunshade curtain 22 to unfold or retract. After the photovoltaic sunshade curtain 22 is unfolded, its internal airflow channels 8 are connected to the receiving port 62 of the exhaust channel 61.

[0026] The output end of the drive motor 26 is fixedly connected to the drive gear 25. The teeth of the drive gear 25 mesh with the teeth of the driven gear 24. When the drive motor 26 is powered on, the drive gear 25 rotates synchronously with the output shaft of the drive motor 26. The rotational motion of the drive gear 25 is transmitted to the driven gear 24 through the meshing teeth, causing the driven gear 24 to rotate in the opposite direction to the drive gear 25. The driven gear 24 is fixedly installed on the outer side of one end of the driven shaft 23. When the driven gear 24 rotates, it drives the driven shaft 23 to rotate synchronously. Synchronous pulleys 53 are fixedly installed at both ends of the driven shaft 23, and synchronous pulleys 53 are also provided inside the guide groove 52. The step wheel 53 and the synchronous wheel 53 inside the guide groove 52 are connected in a closed loop by the synchronous belt 54. When the driven shaft 23 rotates, it drives the synchronous wheels 53 at both ends to rotate synchronously. The synchronous wheels 53 mesh with the tooth grooves on the inner wall of the synchronous belt 54 through their teeth, converting the rotational motion into the linear motion of the synchronous belt 54. When the synchronous belt 54 is running, it drives the slide rod 7, which is fixedly connected to it, to slide along the guide groove 52. The slide rod 7 further drives the two ends of the photovoltaic sunshade curtain 22 to move synchronously, thereby realizing the smooth unfolding and retraction of the photovoltaic sunshade curtain 22 along the direction of the guide groove 52, ensuring that the two sides of the photovoltaic sunshade curtain 22 always remain synchronous during the movement, and avoiding the tilt or jamming caused by the asynchronous movement of the two sides.

[0027] Multiple guide channels 34 are arranged at equal intervals along the length of the guide box 33, and the outlets of the multiple guide channels 34 all face the surface of the car dashboard. The guide box 33 is fixedly installed on one side of the main body box 1 and extends along the length of the main body box 1. The interior of the guide box 33 forms a cavity that communicates with the air outlet of the first axial flow fan 32. When the first axial flow fan 32 is running, the airflow generated enters the cavity inside the guide box 33. Since the multiple guide channels 34 are arranged at equal intervals along the length of the guide box 33, and each guide channel 34 communicates with the cavity inside the guide box 33, the airflow entering the guide box 33 is evenly dispersed in the cavity and then flows out simultaneously through each guide channel 34. The equidistant arrangement ensures that the airflow is evenly distributed throughout the entire length of the guide box 33, so that the airflow of each guide channel 34 is consistent and avoids the situation of excessive or insufficient local airflow. The outlets of the air guide slots 34 all face the surface of the car dashboard. After the airflow flows out of the air guide slots 34, it blows directly onto the dashboard surface, allowing the airflow to concentrate on the dashboard, the area with the highest temperature after being directly exposed to sunlight. The heat on the dashboard surface is quickly carried away by the airflow, effectively reducing the temperature of the dashboard and its surrounding area. Since the dashboard is located at the lower front of the car, the airflow naturally flows towards the roof after blowing on the dashboard, thus forming a directional airflow path from the dashboard surface to the roof, providing a basis for the subsequent exhaust of hot air from the roof.

[0028] The working principle of this invention is as follows: When the vehicle is stationary with the engine off, and the vibration sensor 41 detects that the vehicle is stationary while the light sensor 42 detects sufficient sunlight, the system enters the pre-activation phase. The internal temperature sensor 43 and the external temperature sensor 44 jointly monitor the temperature difference between the inside and outside of the vehicle in real time. Once the interior temperature rises to a preset activation threshold, the control module 46 makes an intelligent decision based on the sensor signals. First, it sends a start command to the drive motor 26. The drive motor 26 rotates and drives the driven gear 24 to rotate via the drive gear 25. The driven gear 24 transmits power to the driven shaft 23. Since both ends of the driven shaft 23 are equipped with synchronous pulleys 53, and each synchronous pulley 53 forms a closed-loop transmission connection with the synchronous pulleys 53 in the guide grooves 52 of the guide rails 51 on both sides via synchronous belts 54, the system... The rotation of the drive shaft 23 drives the synchronous belts 54 on both sides to rotate synchronously. The slide rod 7, which is fixedly connected to the synchronous belt 54, then slides smoothly along the guide groove 52 of the guide rail 51. This causes the photovoltaic sunshade 22, which is wrapped around the outer wall of the roller blind shaft 21, to be gradually released from the roller blind shaft 21 and unfold downwards along the surface of the windshield. At the same time as the sunshade unfolds into place, the control module 46 simultaneously starts the first axial flow fan 32 and the second axial flow fan 63. The first axial flow fan 32 draws in the relatively low-temperature fresh air from outside through the air inlet 31 and sends it into the air guide box 33. The multiple air guide grooves 34 on the surface of the air guide box 33 evenly distribute the air and guide it to the surface of the car dashboard. The cold air continuously absorbs heat from the car interior as it flows over the dashboard and gradually heats up. The hot air naturally cools down due to its lower density. The hot air rises and gathers towards the roof area. At this time, the multiple receiving ports 62 at the bottom of the exhaust duct 61 correspond to the tops of the multiple guide channels 8 inside the photovoltaic sunshade 22. This allows the hot air rising to the roof area to be collected by the receiving ports 62 through the guide channels 8 and enter the exhaust duct 61. The negative pressure generated by the operation of the second axial flow fan 63 forces the hot air to be transported to the exhaust port 64 and finally discharged outside the vehicle. This establishes a complete directional airflow circulation path inside the vehicle, from bottom air supply, through the dashboard surface, through the guide channels 8 inside the sunshade, and finally discharged from the top. This circulation continuously provides power to the fan with the help of the solar-powered photovoltaic sunshade 22. The battery 45, as an auxiliary energy storage unit, continues to maintain system operation when there is insufficient sunlight. When the temperature sensor detects that the interior temperature has dropped to a certain level, the system continues to operate. When the target area or light intensity is significantly reduced, the control module 46 sends a reverse command to the drive motor 26. The drive motor 26 reverses, causing the driven shaft 23 to rotate in the opposite direction, which in turn drives the synchronous belt 54 to rotate in the opposite direction. The slide bar 7, together with the photovoltaic sunshade curtain 22, slides upward along the guide groove 52 and rewinds onto the outer wall of the roller shutter shaft 21 to complete the reset. At the same time, the control module 46 turns off the fan to restore the system to standby state. When the vibration sensor 41 detects that the vehicle is starting, the control module 46 also triggers the emergency retraction action. The control module 46 collects data from each sensor in real time and performs comprehensive logical judgment to ensure that the opening and closing of the sunshade curtain and the start and stop of the airflow are automatically adjusted according to the actual environmental changes, thereby realizing the intelligent, automated and energy-efficient car sunshade and cooling function.
