Abstract
Description
Technical Field
[0001] This application relates to the field of automotive heat dissipation and cooling technology, and in particular to a temperature regulation device. Background Technology
[0002] As automotive design moves towards lightweight and minimalist designs, glass panoramic sunroofs have become the mainstream design solution for automotive roof structures due to their unique advantages. This design eliminates the need for additional roof lining decorations, reduces the number of parts, and can be directly installed onto the vehicle body using adhesive. Furthermore, glass panoramic sunroofs occupy minimal space in the vehicle's height direction, effectively ensuring ample living space for passengers inside the vehicle.
[0003] However, existing glass sunroof designs have significant temperature control issues: in hot weather or high-temperature environments, infrared and ultraviolet rays from sunlight penetrate directly through the glass sunroof, causing the interior temperature to rise rapidly and resulting in intense discomfort for passengers. This is especially true when the air conditioning is on, where the interior temperature becomes polarized; passengers may feel cool or even cold on some parts of their body, while their heads remain hot and exposed to the sun. To address this problem, some glass sunroofs employ silver plating or laminated heat insulation layers. However, silver plating can interfere with cell phone signals and electronic device communication within the vehicle, while laminated heat insulation increases the complexity and cost of the sunroof glass manufacturing process. Additionally, adding sunshades is also widely used, but sunshades are expensive to manufacture and take up interior space, contradicting the original space-saving design of glass sunroofs.
[0004] In summary, while existing glass sunroofs achieve lightweighting and simplification, they struggle to provide effective sunshade and heat insulation. Furthermore, existing solutions suffer from drawbacks such as limited effectiveness, high manufacturing costs, and the need to occupy interior space. Summary of the Invention

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0025] To address the challenges of achieving effective sun shading and heat insulation while maintaining the advantages of lightweight, minimalist design, and small space occupation, and the technical issues of limited effectiveness, high manufacturing costs, and space occupation in existing solutions, this application provides a temperature regulation device. This device can collect real-time temperature data from the inner surface of the sunroof, the top of the vehicle interior, and the bottom of the vehicle interior. The control system automatically activates the spray system and selects the cooling mode based on multi-dimensional temperature feedback. This device can quickly reduce the sunroof temperature in high-temperature environments, suppress the rise in vehicle interior temperature, and does not occupy vehicle interior space, resulting in low cost and a good user experience.
[0026] This application provides a temperature regulating device for a vehicle, the temperature regulating device comprising: The spray system 2 is configured to spray a preset medium onto the vehicle's canopy 1. The working modes of the spray system 2 include at least a first cooling mode and a second cooling mode. The spray system 2 includes one or more nozzles 22. The temperature detection system is configured to detect the temperature inside the vehicle's sunroof, the temperature at the top of the vehicle interior, and the temperature at the bottom of the vehicle interior; and The control system is configured to switch or maintain the working mode of the spray system 2 based on the temperature inside the canopy, the temperature at the top of the vehicle, and the temperature at the bottom of the vehicle. The preset medium used in both the first and second cooling modes includes water. The water flow rate of the spray system 2 in the first cooling mode is greater than that in the second cooling mode.
[0027] The nozzles 22 of the spray system 2 are located on the top of the vehicle sunroof 1. The spray surface can preferably cover the entire sunroof 1, or it can only cover the part of the sunroof 1 corresponding to the passenger position.
[0028] The temperature detection system may include multiple temperature sensors, which are installed at multiple detection locations. These sensors obtain the temperatures of the sunroof interior, the top of the vehicle interior, and the bottom of the vehicle interior, respectively, based on their installation locations. Specifically, the sunroof interior temperature refers to the temperature of the surface of the sunroof 1 facing the vehicle interior; this temperature characterizes the surface temperature of the sunroof glass. The top of the vehicle interior temperature refers to the temperature near the heads of the occupants, using the headrest as a reference. The bottom of the vehicle interior temperature refers to the temperature near the legs of the occupants, using the seat surface as a reference.
[0029] The control system determines whether the sprinkler system 2 needs to be activated based on the temperature inside the sunroof, the temperature at the top of the vehicle interior, and the temperature at the bottom of the vehicle interior. If the system determines that the sprinkler system 2 needs to be activated, it determines and selects an appropriate operating mode. After the sprinkler system 2 is activated, the temperature detection system will continue to provide real-time feedback on the temperature inside the sunroof, the temperature at the top of the vehicle interior, and the temperature at the bottom of the vehicle interior. The control system then determines whether to switch or maintain the operating mode of the sprinkler system 2 based on the detected temperatures.
[0030] In this embodiment, the first cooling mode is set to rapid cooling mode. In the first cooling mode, the spray system 2 can quickly spray a large amount of high-pressure water to rapidly reduce the temperature of the canopy 1. The second cooling mode is set to gentle cooling mode. In the second cooling mode, the spray system 2 sprays less water to gradually reduce the temperature of the canopy 1.
[0031] The embodiments disclosed in this application collect temperature data in real time from the inner surface of the sunroof 1, the top of the vehicle interior, and the bottom of the vehicle interior using a temperature detection system. The control system automatically starts the spray system 2 and automatically selects the cooling mode based on multi-dimensional temperature feedback, which can quickly reduce the temperature of the sunroof 1 in high-temperature environments and suppress the rise in the temperature inside the vehicle.
[0032] The spray nozzles 22 of the spray system 2 are externally mounted on the top of the sunroof 1, without occupying interior space. This fully continues the lightweight, minimalist, and space-saving design principles of the glass sunroof 1, avoiding the reduction of interior space caused by adding a sunshade. At the same time, the preset medium is mainly water, which is significantly cheaper than electric sunshades, silver-plated glass, and laminated heat-insulating glass. It will also not interfere with mobile phone signals or electronic device communications inside the vehicle, ultimately achieving a balance between cooling, cost control, and user experience.
[0033] The first cooling mode can handle extreme high-temperature scenarios by using high-flow, high-pressure water spray to rapidly cool the Sky Canopy 1, effectively solving the cooling needs. The second cooling mode uses low flow to achieve gentle cooling, maintaining a suitable temperature while reducing water waste.
[0034] Meanwhile, this application dynamically adjusts the spray mode based on feedback from the temperature at the top and bottom of the vehicle interior, which can effectively reduce the temperature difference between the top and bottom of the vehicle interior, preventing passengers from experiencing a disconnect between feeling cool or even cold on their bodies and feeling hot and exposed to the sun on their heads, thus improving driving and riding comfort.
[0035] In addition, the control system is equipped with a spray system button and manual operation buttons corresponding to the first cooling mode and the second cooling mode, which can be manually started by the driver and passengers and selected the corresponding cooling mode according to actual needs.
[0036] In some embodiments, the preset medium used by the spray system 2 in the second cooling mode further includes gas.
[0037] In the second cooling mode, gas and water form a mixed spray medium. The addition of gas atomizes the water flow, creating an atomized layer on the canopy 1. This atomized layer has higher heat absorption efficiency, allowing it to remove heat from the canopy 1 more quickly. Simultaneously, the atomized layer can also rapidly absorb heat from the air above the canopy 1, further enhancing its cooling effect. Furthermore, the cooling efficiency of atomized water droplets is higher than that of an equal volume of liquid water. Therefore, to achieve the same cooling effect, the amount of water required for gas-liquid mixing is far less than that required for simple water spraying, reducing water consumption and conserving water resources.
[0038] Meanwhile, the atomized water droplets are small in diameter, evaporate easily, and are unlikely to leave water stains on the surface of the canopy 1. Furthermore, thanks to the small droplet diameter, no obvious watermarks or flow marks are formed on the surface of the canopy 1 during the cooling process; and the noise generated during cooling is also relatively low, achieving a gentle and quiet cooling effect.
[0039] In some embodiments, the control system is configured as follows: When the temperature inside the canopy exceeds the first threshold and the difference between the temperature at the top and bottom of the vehicle exceeds the third threshold, the spray system 2 will be switched to or maintained in the first cooling mode. When the temperature inside the canopy is greater than or equal to the second threshold and less than or equal to the first threshold, and the difference between the temperature at the top of the vehicle and the temperature at the bottom of the vehicle is greater than or equal to the fourth threshold and less than or equal to the third threshold, the spray system 2 will be switched to or maintained in the second cooling mode. When the temperature inside the canopy is less than the second threshold and the difference between the temperature at the top and bottom of the vehicle is less than the fourth threshold, the sprinkler system 2 is turned off.
[0040] The first threshold is 50°C. At this temperature, the occupants in the driving and riding space can clearly feel the difference between the head temperature and the bottom temperature. The temperature range of the third threshold is 4°C-5°C. In this embodiment, the third threshold is 4°C.
[0041] When the temperature inside the sunroof exceeds 50°C and the temperature difference between the top surface and the bottom surface of the vehicle exceeds 4°C, it indicates that the temperature of sunroof 1 is too high, causing great discomfort to the driver and passengers. Rapid cooling is required. At this time, the sprinkler system 2 switches to or maintains the first cooling mode, using high-flow-rate, high-pressure water spray to rapidly cool sunroof 1, reduce the temperature difference between the top surface and the bottom surface of the vehicle, and quickly alleviate the discomfort of the driver and passengers.
[0042] The second threshold is 45°C. At this temperature, the occupants in the driving and riding space can feel a difference between the head temperature and the bottom temperature. The temperature range of the fourth threshold is 1°C-2°C. In this embodiment, the fourth threshold is 1°C.
[0043] When the temperature inside the sunroof is greater than or equal to 45℃ and less than or equal to 50℃, and the temperature difference between the top surface and the bottom surface of the vehicle is greater than or equal to 1℃ and less than or equal to 4℃, it indicates that the temperature of sunroof 1 is slightly high, and the driver and passengers are slightly uncomfortable or have not yet felt any discomfort. At this time, the spray system 2 switches to or maintains the second cooling mode, and uses the atomization layer to gently cool sunroof 1. While effectively controlling the temperature of sunroof 1, it also takes into account the gentleness and quietness of the cooling process and the absence of visual interference.
[0044] When the temperature inside the canopy is less than 45°C and the temperature difference between the top surface and the bottom surface of the vehicle is less than 1°C, the sprinkler system 2 will be turned off.
[0045] This application constructs a multi-dimensional and refined temperature judgment system by setting a first threshold (50℃), a second threshold (45℃), a third threshold (4℃), and a fourth threshold (1℃). It can accurately identify three types of scenarios: high temperature and significant temperature difference in the canopy 1, slightly high temperature and slight temperature difference in the canopy 1, and suitable temperature and minimal temperature difference. This enables on-demand cooling and ensures that the cooling action matches the actual comfort needs of the driver and passengers.
[0046] In addition, during the spray cooling process, the temperature detection system continues to provide real-time feedback on the surface temperature of the canopy 1, the temperature of the top of the vehicle interior, and the temperature of the bottom of the vehicle interior. The control system determines whether to switch or maintain the operating mode of the spray system 2 based on the detected temperatures. This avoids water waste caused by the spray system 2 continuing to spray even when the temperature of the canopy 1 has dropped to a suitable range (i.e., below 45°C), and also prevents insufficient or excessive cooling due to failure to switch modes in a timely manner, effectively improving resource utilization.
[0047] In addition, based on the experiences of drivers and passengers, the following supplementary explanations are provided: When the temperature inside the canopy is greater than 50°C, and the temperature difference between the top surface and the bottom surface of the vehicle is greater than or equal to 1°C and less than or equal to 4°C, the driver and passengers can manually turn on the sprinkler system 2 and select the first or second cooling mode according to their personal physical sensation.
[0048] When the temperature inside the skylight is greater than 50°C and the temperature difference between the top surface and the bottom surface of the vehicle is less than 1°C, it indicates that although the temperature of skylight 1 is high, the passengers do not feel uncomfortable. Sprinkler system 2 is then turned off to reduce energy consumption.
[0049] When the temperature of the canopy is greater than or equal to 45℃ and less than or equal to 50℃, and the temperature difference between the top surface and the bottom surface of the vehicle is greater than 4℃, the driver and passengers can manually turn on the sprinkler system 2 and select the first or second cooling mode according to their personal physical feeling.
[0050] When the temperature of the canopy is greater than or equal to 45℃ and less than or equal to 50℃, and the difference between the temperature of the roof and the temperature of the bottom of the vehicle is less than 1℃, it indicates that the driver and passengers do not feel uncomfortable. Sprinkler system 2 is then turned off to reduce energy consumption.
[0051] When the temperature of the roof is less than 45℃ and the temperature difference between the top surface and the bottom surface of the vehicle is greater than or equal to 1℃, it indicates that the large temperature difference between the top surface and the bottom surface of the vehicle is not caused by the roof 1. Therefore, the sprinkler system 2 is turned off, and the driver and passengers can check the vehicle's air conditioning equipment to find out the cause of the temperature difference.
[0052] In some embodiments, the spray system 2 includes: Storage tank 21; The spray pump 23 has its inlet connected to the storage tank 21 and its outlet connected to one or more spray heads 22.
[0053] like Figures 2 to 4As shown, in this embodiment, multiple nozzles 22 are provided, and each nozzle 22 is connected to the outlet of the spray water pump 23. The nozzles 22 have a guiding function and can control the spray direction and spray range of the preset medium. Generally, the nozzles 22 can be set on the side of the vehicle top near the front of the vehicle, with the spraying end of the nozzles 22 facing the rear of the vehicle. In this way, the streamlined design of the vehicle itself and the airflow generated when the vehicle moves forward can be used to make the sprayed water or atomized water quickly cover the entire glass of the sunroof 1.
[0054] like Figure 2 As shown, when the vehicle roof is not equipped with a roof rack but has a lidar 4 installed, the spray nozzle 22 must be positioned away from the lidar 4 installation area to avoid damage to the lidar 4 or interference with its detection accuracy during spraying. When the vehicle roof is equipped with a roof rack, the spray nozzle 22 can be positioned below the roof rack, such as... Figure 3 As shown, in this embodiment, there are four nozzles 22 in total. Two nozzles 22 are located at both ends of the roof near the front of the vehicle, and the other two nozzles 22 are located at both ends of the middle of the roof, so as to cover the area of the canopy 1.
[0055] Differentiated and diversified configurations enhance the adaptability of the temperature control device to different vehicle models, expanding its application scope. The arrangement of multiple nozzles 22 ensures that all parts of the canopy 1 receive uniform media spraying, forming a uniform spray layer on the surface of the canopy 1. This ensures that the temperature in all areas of the canopy 1 decreases synchronously, improving cooling uniformity.
[0056] In some embodiments, the vehicle includes an air conditioner; The liquid storage tank 21 has a water inlet pipe 211, which is connected to the water outlet pipe 3 of the air conditioner.
[0057] like Figure 4 As shown, by connecting the inlet of the storage tank 21 to the outlet pipe 3 of the air conditioner, the condensate generated during the operation of the air conditioner can be directly recycled as the water source in the preset medium of the spray system 2. This eliminates or reduces the need for adding tap water, saving the need for manual water replenishment and enabling the resource utilization of wastewater, thus reducing water waste. Furthermore, the air conditioner condensate is relatively clean with low impurity content, and will not pollute the surface of the canopy 1.
[0058] In some embodiments, the liquid storage tank 21 further includes: Drain pipe 213; Three-way solenoid valve 212, the inlet of three-way solenoid valve 212 is connected to outlet pipe 3, the first outlet of three-way solenoid valve 212 is connected to inlet pipe 211, and the second outlet of three-way solenoid valve 212 is connected to drain pipe 213; and A water level sensor is connected to the control system and configured to detect the water level in the storage tank 21. The control system is configured to control the three-way solenoid valve 212 to operate or output prompt information based on the water level in the storage tank 21.
[0059] Specifically, when the water level in the storage tank 21 is greater than or equal to the fifth threshold, the three-way solenoid valve 212 is controlled to connect the outlet pipe 3 and the drain pipe 213. When the water level in the storage tank 21 is less than the fifth threshold, control the three-way solenoid valve 212 to connect the outlet pipe 3 and the inlet pipe 211. When the water level in storage tank 21 is less than or equal to the sixth threshold, a prompt message is output.
[0060] like Figure 4 As shown, the water level sensor can monitor the water level in the storage tank 21 in real time and feed the water level detection signal back to the control system in real time. In this embodiment, the fifth threshold is the high water level threshold, indicating that the storage tank 21 is full of water, and the sixth threshold is the low water level threshold, indicating that the water level in the storage tank 21 is insufficient.
[0061] When the water level in the storage tank 21 is greater than or equal to the high water level threshold, it indicates that there is sufficient water in the storage tank 21. If water is added continuously, it will cause water to overflow. At this time, the control system controls the three-way solenoid valve 212 to operate, so that the inlet of the three-way solenoid valve 212 is connected to the second outlet, that is, the outlet pipe 3 is connected to the drain pipe 213, so that the condensate water generated by the air conditioner is directly discharged through the drain pipe 213, and the water supply to the storage tank 21 is stopped.
[0062] When the water level in the storage tank 21 is lower than the high water level threshold, it indicates that the water level in the storage tank 21 is within a suitable range and condensate needs to be continuously replenished to ensure the operation of the spray system 2. At this time, the control system controls the three-way solenoid valve 212 to connect the inlet of the three-way valve with the first outlet, that is, the outlet pipe 3 is connected with the inlet pipe 211, so that the condensate generated by the air conditioner continuously flows into the storage tank 21.
[0063] When the water level in the reservoir 21 is lower than the low water level threshold, it indicates that the water in the reservoir 21 is insufficient and may not meet the water supply requirements of the spray system 2. At this time, in addition to continuously allowing the condensate generated by the air conditioner to flow into and out of the reservoir pipe, the control system will also output prompt information, such as the dashboard indicator light illuminating and the car audio system ringing a bell, to remind the driver and passengers to check and / or replenish the water in time.
[0064] By utilizing real-time feedback from a water level sensor and bidirectional switching of the three-way solenoid valve 212, the risks of water overflow and water shortage can be avoided, solving the dual technical problems of excessive water replenishment and insufficient water supply. Furthermore, when the liquid storage tank is not full, air conditioner condensate can be continuously recycled, preventing water waste. Even when the liquid storage tank 21 is full, the normal drainage of the air conditioner will not be affected, achieving recycling and system compatibility.
[0065] In some embodiments, a filter element 214 is installed on the inlet pipe 211 and / or the outlet pipe 3.
[0066] The filter element 214 installed on the inlet pipe 211 and / or outlet pipe 3 can accurately intercept trace impurities in the air conditioner condensate, reducing the risk of impurities entering the three-head solenoid valve and the nozzle 22, and effectively avoiding the problem of uneven spray volume and reduced atomization effect caused by impurities clogging the nozzle 22.
[0067] In some embodiments, the spray system 2 further includes a water injection pipe 25, which is connected to the liquid storage tank 21.
[0068] like Figure 4 As shown, the water inlet pipe 25 provides a manual water replenishment method for the reservoir 21, effectively addressing scenarios where air conditioning condensate recovery is insufficient. Passengers can manually add clean water through the water inlet pipe 25 to ensure the water level in the reservoir 21 remains within a suitable range, preventing the sprinkler system 2 from failing to start or experiencing interrupted cooling due to water shortage. Additionally, antifreeze can be added to the reservoir 21 through the water inlet pipe 25 to prevent the water in the reservoir 21 from freezing in winter or extremely cold weather, thus affecting its use.
[0069] Furthermore, such as Figure 5 As shown, the sprinkler system 2 also includes: Mixing chamber 26; A mixing pipe 27 is connected between a mixing chamber 26 and one or more nozzles 22; Spray water pipe 24 is connected between the outlet of spray water pump 23 and mixing chamber 26; Spray air pump 28; and The spray pipe 29 is connected between the air outlet of the spray pump 28 and the mixing chamber 26.
[0070] The mixing chamber 26 serves as a gas-liquid mixing hub, working in conjunction with the spray air pump 28 to provide stable high-pressure air. The spray water pump 23 delivers high-pressure water, allowing the high-pressure water and high-pressure air to mix thoroughly in a turbulent flow within the mixing chamber 26, forming atomized water vapor with uniform particle size and strong dispersion. Optionally, for vehicles equipped with air springs, which already have a high-pressure air pump and a high-pressure air tank, the spray air pump 28 is unnecessary; the spray air pipe 29 can be directly connected to the high-pressure air tank.
[0071] In some embodiments, the operating modes of the spray system 2 further include a first cleaning mode and a second cleaning mode, wherein... The preset medium used in the first cleaning mode is gas; The second cleaning mode has a first stage and a second stage. The preset medium used in the first stage is water, and the preset medium used in the second stage is gas. The control system is configured to control the spray system 2 to start either the first cleaning mode or the second cleaning mode according to external operation commands.
[0072] The control system also features manual operation buttons corresponding to the first and second cleaning modes, allowing occupants to select the appropriate cleaning mode based on the level of dirt on the canopy 1. When there is dust, leaves, or other light debris on the canopy 1, the first cleaning mode can be activated, which simply sprays high-pressure gas to blow the light debris away from the vehicle. When there is heavy dust, bird droppings, decaying leaves, or other debris on the canopy 1, the second cleaning mode can be activated. In the first stage, high-pressure water is used to wash away the debris. After the first stage, the second stage uses high-pressure gas to blow away any remaining water from the vehicle, accelerating the drying of the canopy 1 and preventing water stains and subsequent adhesion of dust and debris.
[0073] Based on the original cooling function, a first cleaning mode and a second cleaning mode have been added, so that the spray system 2 has the dual functions of temperature regulation and skylight 1 cleaning. There is no need to install an independent cleaning device on the vehicle, saving roof installation space. This is in line with the design concept of lightweight and simplification, and also reduces the manufacturing cost and installation complexity of multiple devices, achieving multiple uses in one device.
[0074] At the same time, a graded cleaning mode is designed according to the type of debris, so that different types of debris can be treated in a targeted manner, and the cleaning is efficient and thorough.
