[0002] During the scorching summer heat, many car owners face significant challenges, including heat dissipation problems, high interior temperatures, and interior aging. To address this issue, various sunshades and sunshades are available on the market, but these products require manual operation, resulting in limited effectiveness and low efficiency.

[0003] This patented technology primarily achieves the goal of automatically deploying or retracting a roll-up sunshade by monitoring the light intensity and temperature on the roof or through terminal APP control. The control device's water spray cooling system regularly sprays and cools the vehicle, achieving more effective and convenient sunshade and heat dissipation. The device requires two motorized reels, a light-sensing temperature sensor, a power module, an intelligent control center, a rollable, soft, reflective sunshade, and a spray device at the front and rear of the vehicle, respectively. The device intelligently performs sunshade and spray cooling based on light-sensing temperature signals. Summary of the Invention

[0004] In order to overcome the shortcomings and deficiencies in the prior art that the unfolding of the sunshade requires manual operation, the purpose of the present invention is to provide an automatic curling heat dissipation sunshade.

[0006] Preferably, the sunshade is a rollable reflective sunshade cloth. The purpose of using a rollable reflective sunshade cloth as a sunshade is to utilize its reflective properties to effectively reflect sunlight. At the same time, the rollable design is convenient for storage and unfolding, achieving efficient sunshade and heat insulation, reducing the temperature rise in the car, and improving riding comfort.

[0007] Preferably, two reels are provided, and the end of the sunshade that is not used for connecting the traction rope is provided on the second reel. The two reels are respectively provided at both ends of the car. By the two reels being respectively located at both ends of the car and connecting the two ends of the sunshade, the sunshade is stably installed and fully covered in the car, ensuring uniform sunshade effect, and at the same time facilitating the automatic retraction and extension of the sunshade through the rotation of the reel.

[0008] Preferably, the sunshade also includes an intelligent control center, which is used to receive control instructions from the terminal to control the driving component so that it drives the roller to rotate to realize the unfolding and reeling of the sunshade. The introduction of the intelligent control center drives the rotation of the roller by receiving and processing terminal control instructions, thereby realizing intelligent and automated control of the sunshade, improving user experience, and making the operation of the sunshade more convenient and flexible.

[0009] Preferably, the intelligent control center has a built-in GSM / GPRS module, which is used to receive and send control instructions from the terminal.

[0011] Preferably, a spray device is provided at the end of the reel, and the spray device includes a water pipe and a nozzle. One end of the water pipe is connected to the nozzle, and the end of the water pipe away from the nozzle is connected to the vehicle water tank. The nozzle has a built-in water pump electrically connected to the intelligent control center and the power module. The water pump is used to make the nozzle spray indirectly after the sunshade is unfolded, and stop working when the sunshade is retracted. The spray device is provided at the end of the reel, and the water pump is controlled by the intelligent control center to realize the automatic spraying effect after the sunshade is unfolded. It not only enhances the sunshade effect, but also can cool the vehicle environment in hot weather and improve ride comfort. At the same time, the spray device stops working when the sunshade is retracted, saving water resources.

[0012] Preferably, a light-sensitive temperature sensor electrically connected to the power module is provided at the end of the reel, and the light-sensitive temperature sensor and the spray device are respectively arranged at both ends of the length direction of the reel. The light-sensitive temperature sensor is electrically connected to the power module and is arranged at the end of the reel. Its function is to monitor the surface temperature of the car in real time and provide temperature data support for the intelligent control center, so as to automatically adjust the working status of the sunshade and the spray device according to temperature changes and realize intelligent temperature control management.

[0013] Preferably, the intelligent control center is used to receive the temperature signal sent by the light-sensitive temperature sensor.

[0024] In order to facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and drawings. The contents mentioned in the embodiments are not intended to limit the present invention.

[0025] See also Figures 1 to 4 As shown, an automatic curling heat dissipation sunshade of the present invention includes a reel 1; it also includes a driving member 2 for driving the reel 1 to rotate, a traction rope 3 is wound around the reel 1, and the end of the traction rope 3 not used for winding around the reel 1 is connected to a sunshade 4, and the end of the sunshade 4 not used for connecting the traction rope 3 and the reel 1 are respectively arranged at both ends in the length or width direction of the car.

[0026] Specifically, the reel 1 is driven to rotate by the driving member 2, and the traction rope 3 wrapped around the reel 1 is used to drive the sunshade curtain 4 to be unfolded or retracted, thereby realizing automatic control of the curling and unfolding of the sunshade curtain 4, which is convenient, fast, saves manpower, and improves the ease of use; one end of the sunshade curtain 4 is connected to the traction rope 3, and the other end of the sunshade curtain 4 and the reel 1 are respectively arranged at both ends in the length or width direction of the car, thereby realizing effective coverage of the sunshade curtain 4 in the car, enhancing the sunshade effect, and providing a good sunshade and heat insulation environment for the car.

[0027] Specifically, in this embodiment, at least two traction ropes 3 are provided. In other embodiments, traction ropes 3 located at both ends of the sunshade 4 in the width direction and traction ropes 3 located in the middle of the sunshade 4 may be provided.

[0028] Specifically, the driving component 2 is a servo motor.

[0029] Specifically, the reel 1 includes an external cover and a rotating rod rotatably arranged inside the cover, and the traction rope 3 and the sunshade 4 are arranged on the rotating rod.

[0030] Specifically, the reel 1 can also be provided with an adsorbent / adhesive component. Placing the reel 1 on the vehicle body via the adsorbent / adhesive component can bring comprehensive and significant benefits in many aspects, including improved installation convenience and flexibility, enhanced stability and safety in use, and optimized overall aesthetics while reducing costs. In terms of installation convenience, adsorbents such as magnets or adhesive components such as strong adhesive stickers greatly simplify the installation process. Users do not need to resort to complex tools or professional installation knowledge. They can simply align the adsorbent with the metal part of the vehicle body for easy adsorption, or stick the adhesive component to the appropriate location on the vehicle body to quickly complete the installation of the reel 1, saving time and effort. This is particularly suitable for self-installation or temporary use scenarios. In terms of installation flexibility, adsorbents and adhesive components allow for greater freedom in the selection of the reel 1 installation location, without being restricted by the vehicle body's original mounting holes. Users can install the reel 1 in different locations, such as above the windshield or near the side windows, based on the interior space layout, personal usage habits, and sunshade requirements, to achieve personalized sunshade curtain 4 layouts that meet diverse usage needs. From the perspective of stability in use, high-quality adsorption components can generate strong magnetic force to ensure that the reel 1 can be firmly adsorbed on the vehicle body during driving, even in the event of bumps, sudden braking or turning, and will not loosen or fall off; if the adhesive component is made of high-performance viscose material, it can also provide a stable adhesive effect, ensuring that the reel 1 is stably fixed and providing reliable support for the normal use of the sunshade 4. In terms of safety, the stable installation method avoids the safety hazards caused by the reel 1 loosening or falling off, preventing it from falling and injuring people in the car or damaging items in the car while the vehicle is driving, thereby ensuring the safety of the driver and passengers. In terms of aesthetics, the installation method of the adsorption components and adhesive components is relatively concealed. Unlike traditional installation methods, they will not leave obvious installation marks on the vehicle body or damage the original structure of the vehicle body. They can keep the vehicle body clean and beautiful, making the sunshade 4 more coordinated with the overall environment inside the vehicle. In terms of cost, this installation method does not require additional drilling holes on the vehicle body or installing complex fixtures, reducing the material and labor costs required for installation. For manufacturers, it can reduce production costs, and for users, it also avoids additional costs that may be incurred due to complex installation.

[0031] Specifically, the sunshade 4 is a rollable reflective sunshade cloth. The purpose of using the rollable reflective sunshade cloth as the sunshade 4 is to utilize its reflective properties to effectively reflect sunlight. At the same time, the rollable design is convenient for storage and unfolding, achieving efficient sunshade and heat insulation, reducing the temperature rise in the car, and improving riding comfort.

[0032] Specifically, reflective sunshades consist of a base material and a reflective layer. The base material is made of synthetic fibers such as polyester and chemical fiber, offering excellent light-blocking properties and durability. The reflective layer is achieved through coating, flocking, or embedded glass beads, reflecting light and enhancing visibility. For example, laser mirror reflective sunshades utilize laser- and mirror-reflective materials to effectively block UV rays and strong sunlight.

[0033] Specifically, two reels 1 are provided, which are the first reel and the second reel respectively. The traction rope 3 is wound on the first reel, and the end of the sunshade 4 not used for connecting the traction rope 3 is provided on the second reel. The two reels 1 are respectively provided at both ends of the car (i.e., the front and rear of the car). By having the two reels 1 respectively located at both ends of the car and connecting the two ends of the sunshade 4, the sunshade 4 is stably installed and fully covered in the car, ensuring uniform sunshade effect, and at the same time facilitating the automatic retraction and extension of the sunshade 4 through the rotation of the reel 1.

[0034] Specifically, a fixing rod 9 is further provided on the sunshade curtain 4 , and the traction rope 3 is pulled to the sunshade curtain 4 via the fixing rod 9 .

[0035] Specifically, the traction rope 3 can be made of synthetic fiber materials such as nylon (polyamide fiber), polyester fiber (terylene) and polypropylene (polypropylene fiber).

[0036] Specifically, the curling heat dissipating sunshade also includes an intelligent control center 5, which is used to receive control instructions from the terminal to control the driving component 2, so that it drives the reel 1 to rotate to realize the unfolding and reeling of the sunshade 4. The introduction of the intelligent control center 5 drives the reel 1 to rotate by receiving and processing terminal control instructions, thereby realizing the intelligent and automatic control of the sunshade 4, improving the user experience, and making the operation of the sunshade 4 more convenient and flexible.

[0037] Specifically, the intelligent control center 5 can be set on the vehicle or on the reel 1.

[0038] Specifically, the intelligent control center 5 has a built-in GSM / GPRS module, which is used to receive and send control instructions from the terminal. The intelligent control center 5 with a built-in GSM / GPRS module receives and sends control instructions through wireless communication, thereby realizing the function of remotely controlling the sunshade 4. Users can control the unfolding and retracting of the sunshade 4 through terminal devices such as mobile phones anytime and anywhere, thereby enhancing the convenience of use.

[0039] Specifically, the curling heat dissipating sunshade also includes a power module 6, which is used to supply power to the intelligent control center 5. The power module 6 provides a stable power supply for the intelligent control center 5, ensuring the normal operation of the intelligent control center 5 and its connected components (such as the drive 2, sensors, etc.), and realizing the continuous and reliable operation of the sunshade 4 system.

[0040] Specifically, in this embodiment, the power module 6 supplies power to each power-demanding module via the intelligent control center 5 .

[0041] Specifically, a spray device 7 is provided at the end of the reel 1. The spray device 7 includes a water pipe and a nozzle. The nozzle is externally arranged on the reel 1, one end of the water pipe is connected to the nozzle, and the end of the water pipe away from the nozzle is connected to the vehicle water tank. The nozzle has a built-in water pump electrically connected to the intelligent control center 5 and the power module 6. The water pump is used to enable the nozzle to spray indirectly after the sunshade 4 is unfolded, and stops working when the sunshade 4 is retracted. The spray device 7 is provided at the end of the reel 1, and the water pump is controlled by the intelligent control center 5 to realize the automatic spraying effect after the sunshade 4 is unfolded, which not only enhances the sunshade effect, but also can cool the vehicle environment in hot weather and improve ride comfort. At the same time, the spray device 7 stops working when the sunshade 4 is retracted, saving water resources.

[0042] Specifically, the reel 1 includes an external cover shell, the nozzle is arranged on the cover shell, and the nozzle and the cover shell are connected via a magnetic member, which is a heterogeneous magnet.

[0043] Specifically, the nozzle is positioned at a specific angle between the two reels 1 via oppositely charged magnets, allowing the sprayed water mist to more evenly cover the entire rollable reflective shade cloth. Since the area between the two reels 1 is the primary area of ​​movement during the shade cloth's unfolding and retraction, this nozzle angle ensures a relatively even spray regardless of the shade cloth's state (fully unfolded, partially unfolded, or retracted), effectively achieving the desired cooling and cleaning effect.

[0044] Specifically, a cut angle for cooperating with a nozzle is provided at the end of the reel 1 so that the nozzle is oriented between the two reels 1 , and the opposite-sex magnet is obliquely arranged at the cut angle of the reel 1 .

[0045] Specifically, a light-sensitive temperature sensor 8 electrically connected to the power module 6 is provided at the end of the reel 1. The light-sensitive temperature sensor 8 and the spray device 7 are respectively arranged at both ends of the length direction of the reel 1. The light-sensitive temperature sensor 8 is electrically connected to the power module 6 and is arranged at the end of the reel 1. The function of the light-sensitive temperature sensor 8 is to monitor the surface temperature of the car in real time and provide temperature data support for the intelligent control center 5, so as to automatically adjust the working status of the sunshade 4 and the spray device 7 according to temperature changes to realize intelligent temperature control management.

[0046] Specifically, a groove body for accommodating the light-sensitive temperature sensor 8 is provided at the end of the reel 1 to protect the light-sensitive temperature sensor 8. In daily use, the automatic curling heat dissipation sunshade 4 may be subjected to external force impact due to the shaking, movement or accidental collision of the vehicle during operation. The groove body at the end of the reel 1 provides a relatively closed and fixed space for the light-sensitive temperature sensor 8, which can prevent the sensor from being directly hit by external objects, reduce the risk of sensor damage due to collision, and extend its service life. The internal environment of the vehicle is complex and there are various sharp or rough surfaces. Placing the sensor in the groove body can reduce the chance of contact with these objects and prevent the sensor surface from being scratched, thereby ensuring the integrity of its optical and temperature sensing components and ensuring that the sensor can work normally.

[0047] Specifically, a sealing strip is provided on the edge of the sunshade 4, and the sealing strip is made of magnetic rubber material; when the sunshade 4 is unfolded to cover the interior of the car, the sealing strip is magnetically adsorbed on the metal frame of the car interior or tightly fits on the non-metallic frame of the car interior through its own elasticity, thereby enhancing the heat insulation and dustproof effect of the sunshade 4 and improving the comfort of the car interior environment.

[0048] Specifically, the intelligent control center 5 is used to receive the temperature signal sent by the light-sensitive temperature sensor 8. When the temperature of the car surface is higher than 45 degrees Celsius, the rotating motor is controlled to unfold the sunshade 4, turn on the spray device 7, and spray at a fixed interval of 30 seconds; when the temperature of the car surface is lower than 45 degrees Celsius, the sunshade 4 is controlled to be retracted and the spray device 7 is turned off. The intelligent control center 5 automatically controls the working status of the sunshade 4 and the spray device 7 according to the temperature signal fed back by the light-sensitive temperature sensor 8, thereby realizing the intelligent adjustment of the shading and cooling functions according to the ambient temperature, which not only ensures the comfort in the car, but also avoids energy waste and improves the energy efficiency of the system.

[0049] Specifically, a solar panel is provided on the cover of the reel 1, and the solar panel is electrically connected to the power module 6; the solar panel can convert solar energy into electrical energy to charge the power module 6, thereby achieving partial energy self-sufficiency of the sunshade 4 system, reducing dependence on the vehicle battery, and improving energy utilization efficiency; at the same time, the solar panel is made of flexible material and can be installed according to the shape of the cover without affecting the overall appearance and structural strength of the cover.

[0050] Specifically, the curling heat dissipation sunshade also includes a wireless signal sending module arranged in the vehicle. When the vehicle is powered on, the wireless signal sending module sends a signal to the intelligent control center 5, and controls the sunshade 4 to be retracted and the spray device 7 to be closed via the driving component 2. The wireless signal sending module is arranged in the vehicle to automatically send a signal to the intelligent control center 5 when the vehicle is powered on, thereby realizing the automatic closing of the sunshade 4 and the spray device 7 when the vehicle starts, avoiding energy waste or equipment damage caused by forgetting to close, and improving the safety and reliability of the system.

[0051] Specifically, in this patented technical solution, a reel 1 is mounted at the front and rear of the vehicle, with a rollable sunshade material installed between the two. Motors are installed at both ends of the reel 1, and rotation controls the unfolding and retraction of the sunshade 4. A spray device 7 consists of a water pipe and an external nozzle. An intelligent control center 5 is used to receive and determine signals from a light and temperature sensor 8 or terminal control signals to automatically control the sunshade 4 and the spray device 7.

[0052] Specifically, the technical solution of this patent includes the following steps:

[0053] S1: Precise deployment and retraction control of sunshade 4 based on rotary motor

[0054] The deployment and retraction of the sunshade 4 are precisely controlled by a rotary motor mounted on reel 1. Reel 1 is covered with a retractable, reflective sunshade fabric. When the deployment command is received, the motor rotates counterclockwise, mechanically rolling the fabric out smoothly. Leveraging its reflective properties, it creates an effective heat-insulating barrier around the vehicle's exterior, achieving efficient sunshade protection. When the retraction command is received, the motor switches to clockwise rotation, driving the rope to reel out and engage with fixed rod 9 to retract the fabric, ultimately achieving automatic retraction of the sunshade 4.

[0055] S2: Intelligent collaborative working mechanism of the spray device 7 and the sunshade 4

[0056] The spray device 7 is tightly connected to the nozzle through a water pipe, and the other end of the water pipe is connected to the vehicle water tank to build a complete water circulation system. The nozzle has a built-in small water pump to provide stable power for the spraying operation. The spray device 7 is intelligently linked to the working state of the sunshade 4. When the sunshade 4 begins to unfold, the spray device 7 starts working synchronously. After the small water pump pressurizes the water in the water tank, it is sprayed out in the form of fine water mist through the nozzle. The spray device 7 will perform periodic spraying according to the fixed time interval pre-set on the terminal device. The user can flexibly adjust the interval time on the terminal according to the actual environmental conditions and usage requirements. Once the sunshade 4 completes the retraction action, the spray device 7 will stop working immediately to avoid waste of water resources.

[0057] S3: Real-time temperature monitoring function of light temperature sensor 8

[0058] The optical temperature sensor 8 relies on the power module 6 to provide stable power support, uses infrared temperature sensing technology to monitor the temperature of the vehicle surface / nearby in real time and accurately, and sends these temperature signals in the form of electrical signals to the intelligent control center 5 in a timely and accurate manner, providing key data basis for subsequent intelligent control decisions.

[0059] S4: Temperature response intelligent control strategy of intelligent control center 5

[0060] The intelligent control center 5 receives real-time temperature signals from the light-sensitive temperature sensor 8. When the vehicle's surface temperature rises above a preset threshold of 45 degrees Celsius, the intelligent control center 5 quickly controls the rotation motor to deploy the sunshade 4 and activates the sprinkler 7, which sprays for 30 seconds at a set interval. This removes heat through evaporation, further enhancing the cooling effect. If the vehicle's surface temperature falls below 45 degrees Celsius, the intelligent control center 5 promptly shuts off the sprinkler 7, restoring the vehicle's interior to its natural state, achieving intelligent and efficient temperature control.

[0061] S5: Automatic reset protection function when the vehicle is powered on

[0062] To ensure safety and convenience when starting the vehicle, the wireless signal transmission module immediately sends a signal to the intelligent control center 5 when the vehicle is powered on. Upon receiving the signal, the intelligent control center 5 controls the sunshade 4 to retract and the spray device 7 to shut down, restoring the entire system to its initial state. This prevents the deployment of the sunshade 4 or the operation of the spray device 7 from affecting the driver's vision and the normal operation of the vehicle, thus providing a strong guarantee for driving safety.

[0063] S6: Remote intelligent control implementation based on GSM / GPRS module

[0064] The intelligent control center 5 features a built-in advanced GSM / GPRS module, bridging the gap between the system and the outside world. This module seamlessly connects the intelligent control center 5 to the terminal app, receiving and sending various control commands from the terminal app. With simple operations on the terminal app, users can remotely control the deployment and retraction of the sunshade 4, the opening and closing of the sprinkler system 7, and the setting of the sprinkler interval, achieving convenient and efficient remote intelligent management.
