[0002] When a car is parked in the summer, the interior temperature can easily rise due to direct sunlight if no measures are taken. This can range from affecting the driving experience to potentially igniting flammable materials inside the car, causing property damage. Cooling the car by turning on the air conditioning consumes more electricity, especially given the current battery shortage, which will undoubtedly reduce the driving range significantly.

[0014] In one exemplary embodiment of this application, the method further includes:

[0015] When the sunshade and heat insulation device receives a roll-up command to switch the air cushion from the unfolded state to the roll-up state, it controls the air cushion to open its exhaust port and / or controls the air pump device to draw air into the air cushion; wherein...

[0016] Controlling the air pump device to draw air into the air cushion includes:

[0017] Obtain the pressure value inside the air cushion;

[0018] If the pressure inside the air cushion is less than a third preset pressure value, the air pump device is controlled to stop sucking air into the air cushion; wherein,

[0019] The third preset pressure value is less than the first preset pressure value.

[0020] The second aspect of this application discloses a sunshade and heat insulation device for use in a vehicle, comprising:

[0021] air cushion;

[0022] An air pump device is connected to the air cushion so as to inflate or de-inflate the air cushion;

[0023] A pressure sensor is connected inside the air cushion to sense the pressure value inside the air cushion.

[0024] The air cushion has a retracted state and an unfolded state relative to the main body of the vehicle, and can switch from the retracted state to the unfolded state; wherein,

[0025] When the air cushion is in the deployed state, the air cushion at least covers the windshield of the vehicle body.

[0026] In one exemplary embodiment of this application, the sunshade and heat insulation device further includes a plurality of snap-fit ​​structures, which are spaced apart from each other on the air cushion for detachable connection with the fixing structure of the vehicle body when the air cushion is in the deployed state.

[0027] In one exemplary embodiment of this application, the sunshade and heat insulation device further includes a drive device and a rotating shaft connected to the vehicle body, the rotating shaft being drively connected to the drive device and capable of rotating relative to the vehicle body; wherein,

Finally, the air pump device is controlled to inflate the air cushion to isolate the heat generated by the air cushion due to sun exposure, reducing the amount of heat transferred to the cabin, and further reducing the maximum temperature inside the cabin of the original vehicle when exposed to direct sunlight. While the air cushion is being inflated by the air pump device, the pressure value inside the air cushion is also obtained by a pressure sensor. If the pressure value inside the air cushion is greater than or equal to a first preset pressure value, the air pump device is controlled to stop inflating the air cushion, thereby ensuring that the air volume of the air cushion can be precisely maintained at the required value.

[0050] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0051] The block diagrams shown in the accompanying drawings are merely functional entities and do not necessarily correspond to physically independent entities. That is, these functional entities can be implemented in software, in one or more hardware modules or integrated circuits, or in different network and / or processor devices and / or microcontroller devices.

For example, some operations / steps can be broken down, while others can be combined or partially combined; therefore, the actual execution order may change depending on the specific circumstances.

[0053] In this application, "multiple" refers to two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone. The character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0054] First, it's important to note that vehicles typically need to be shaded from the sun during the summer to prevent the cabin temperature from rising due to direct sunlight. It's crucial to understand that a high cabin temperature can negatively impact the driving experience; in severe cases, the intense heat could ignite flammable materials inside the cabin, causing property damage.

[0055] Generally speaking, if you directly install a sunshade to block the windshield from the sun, it will not only have a negligible effect on reducing the temperature, but also take up interior space and affect the overall aesthetics and ride comfort of the vehicle. On the other hand, external sunshades are very dangerous while the vehicle is in motion, and the sliding rails of the sunshades are prone to damage, resulting in high maintenance costs.

[0056] Based on the above problems, this embodiment provides a sunshade and heat insulation device 10 to effectively isolate the heat generated by the vehicle due to sun exposure from being transferred to the vehicle's cabin when the vehicle is parked, thereby reducing the maximum temperature inside the vehicle's cabin when exposed to the sun.

[0057] Combination Figures 1 to 12 The following is a detailed introduction to the specific structure and working principle of the sunshade and heat insulation device 10:

[0058] Combination Figures 8 to 10 As shown, the sunshade and heat insulation device 10 includes an air cushion 11. In order to facilitate the air cushion 11 to fit the windshield 12 and roof 13 of the vehicle after inflation, so that it fits tightly against the roof 13 and windshield 12, the shape of the air cushion 11 can be designed as an arc structure according to the shape of the windshield 12 and roof 13 of the vehicle.

[0059] It should be understood that the size of the air cushion 11 can be adapted to the size of the vehicle to ensure that the air cushion 11 can at least cover the windshield 12 of the vehicle. Preferably, the air cushion 11 can cover the entire body 20 of the vehicle, that is, including covering the side windshields and the rear windshield of the vehicle.

[0060] In this embodiment, the air cushion 11 has a retracted state and an extended state relative to the vehicle body 20, and can switch between the retracted state and the extended state. When the air cushion 11 is in the extended state, the air cushion 11 at least covers the windshield 12 of the vehicle body 20; when the air cushion 11 is in the retracted state, the air cushion 11 can be completely stored inside the vehicle body 20 to avoid increasing the drag coefficient during driving.

[0061] Combination Figure 3 As shown, the sunshade and heat insulation device 10 also includes an air pump device 14, which is connected to the air cushion 11 so as to inflate or de-inflate the air cushion 11.

[0062] It should be understood that during the process of switching the air cushion 11 from the retracted state to the unfolded state, or after it is in the unfolded state, the air cushion 11 can be inflated by the air pump device 14 so as to achieve the sunshade function through the air cushion 11, and further insulate the body body 20 with air, thereby reducing the temperature inside the vehicle.

[0063] In addition, when the air cushion 11 needs to be stored, air can be vented not only through the air vent 101 of the air cushion 11, but also by the air pump device 14 to draw air into the air cushion 11 to vent the air cushion 11.

[0064] In this embodiment, the air pump device 14 is detachably connected to the air cushion 11, thereby facilitating the individual repair or replacement of the air cushion 11 or the air pump device 14.

[0065] Combination Figure 4 As shown, the sunshade and heat insulation device 10 also includes multiple snap-fit ​​structures 15, which are spaced apart from each other on the air cushion 11 for detachable connection with the fixing structure of the vehicle body 20 when the air cushion 11 is in the deployed state. This facilitates the detachment of the air cushion 11 while ensuring the stability of the air cushion 11 relative to the vehicle body 20 when it is in the deployed state.

[0066] In this embodiment, multiple snap-fit ​​structures 15 are arranged around the edge of the air cushion 11, and the main body 20 of the vehicle body is provided with corresponding fixing structures that cooperate with the snap-fit ​​structures 15, so that the air cushion 11 and the main body 20 of the vehicle body can be detached and connected through the cooperation of the fixing structures and the snap-fit ​​structures 15.

[0067] Of course, in other embodiments, the sunshade and heat insulation device 10 can also be connected to the vehicle body 20 via suction cups.

[0068] Combination Figure 3 As shown, the sunshade and heat insulation device 10 also includes a drive device and a rotating shaft 163 connected to the vehicle body 20. The rotating shaft 163 is connected to the drive device and can rotate relative to the vehicle body 20. When the air cushion 11 is in the retracted state, the air cushion 11 is wound around the rotating shaft 163 so that the sunshade and heat insulation device 10 can be hidden and stored inside the vehicle body 20.

[0069] For example, the drive device includes a drive motor 161 and a gear structure 162. The gear structure 162 includes a driving gear and a driven gear meshing with the driving gear. The drive motor 161 is connected to the driving gear, and the rotating shaft 163 is connected to the driven gear.

[0070] In this embodiment, the axial direction of the rotating shaft 163 is parallel to the wheel track direction of the vehicle, and the rotating shaft 163 can rotate relative to the vehicle body 20 along its axis under the drive of the drive motor 161 and the drive motor 162.

[0071] It should be understood that when the rotating shaft 163 rotates counterclockwise or clockwise along its axis under the drive of the drive motor 161, the air cushion 11 can be successively wrapped around the circumferential side of the rotating shaft 163, thereby realizing the self-unfolding state to the winding state.

[0072] In this embodiment, combined with Figure 5 As shown, the sunshade and heat insulation device 10 also includes a pressure sensor 17, which is connected inside the air cushion 11 to sense the pressure value inside the air cushion 11 and thus determine whether there is enough gas inside the air cushion 11.

[0073] For example, the pressure sensor 17 can be located at the vent 101 inside the air cushion 11 to more accurately detect the pressure value inside the air cushion 11.

[0074] It should be understood that when the pressure sensor 17 senses that the pressure value inside the air cushion 11 is insufficient, the air pump device 14 can continue to inflate the air cushion 11 to replenish the pressure value inside the air cushion 11. When the pressure sensor 17 senses that the pressure value inside the air cushion 11 is about to exceed the safe pressure value of the air cushion 11, the air pump device 14 can be stopped from inflating the air cushion 11 and the air cushion 11 can be sucked in; or, the air pump device 14 can be stopped from inflating the air cushion 11 and the exhaust port 101 of the air cushion 11 can be opened until the pressure value inside the air cushion 11 is less than or equal to its safe pressure value.

[0075] In this embodiment, if the vehicle requires sun protection, the air cushion 11 can be switched to the deployed state relative to the vehicle's main body 20, at least covering the windshield 12 of the main body 20, to prevent the vehicle's center console and other interior components from being exposed to direct sunlight. Simultaneously, during the process of switching the air cushion 11 to the deployed state relative to the vehicle's main body 20, or after the air cushion 11 is deployed, it can be inflated by the air pump device 14 to insulate the vehicle's main body 20 with air, further reducing the temperature inside the vehicle. Furthermore, a pressure sensor 17 is installed inside the air cushion 11, which can continuously monitor the pressure value inside the air cushion 11. This allows the air pump device 14 to adjust the gas volume inside the air cushion 11 according to the pressure value, maintaining the pressure value within the air cushion 11 within a stable range. Therefore, this sunshade and heat insulation device 10 can effectively prevent the heat generated by the vehicle being exposed to direct sunlight from being transferred to the vehicle's cabin when the vehicle is parked, thereby reducing the maximum temperature inside the vehicle's cabin when exposed to direct sunlight.

[0076] In addition, the sunshade and heat insulation device 10 may also include a guide structure (not shown) for guiding the air cushion 11 when it switches from the retracted state to the unfolded state.

[0077] For example, the guide structure includes a guide rod, a first telescopic rod, and a second telescopic rod. The guide rod is connected to the end of the air cushion 11 away from the rotation axis 163. One end of the first telescopic rod and the second telescopic rod are used to connect to the vehicle body 20. The other ends of the first telescopic rod and the second telescopic rod are respectively connected to the two ends of the guide rod along the axial direction of the guide rod and are driven to extend and retract by a drive assembly.

[0078] Optionally, the length of the guide rod is equal to or greater than the width of the windshield 12, and the width of the air cushion 11 is equal to or greater than the width of the windshield 12.

[0079] It should be understood that the first telescopic rod, the second telescopic rod, and the guide rod are connected to form a semi-enclosed structure. When the air cushion 11 is in the deployed state, it is located within the semi-enclosed structure to completely cover the windshield 12. Specifically, during the deployment of the air cushion 11, the first telescopic rod and the second telescopic rod also extend simultaneously, pushing the guide rod along the extension direction of the vehicle's A-pillar towards one side of the windshield 12 until the guide rod pulls the air cushion 11 to cover the windshield 12. Due to the presence of the guide rod, the air cushion 11 can be almost completely deployed in its width direction. Furthermore, the presence of the first and second telescopic rods almost eliminates the need for manual pulling of the air cushion 11 to cover the windshield 12.

[0080] Furthermore, combined Figure 6 As shown, this embodiment also provides a vehicle, including the aforementioned sunshade and heat insulation device 10 and the vehicle body 20. The sunshade and heat insulation device 10 is connected to the engine compartment or the rear luggage compartment of the vehicle body 20, thereby effectively isolating the heat generated by the vehicle due to sun exposure from being exposed to the sun to be transferred to the vehicle's cabin, ultimately reducing the maximum temperature inside the cabin of the original vehicle when exposed to the sun.

[0081] In one embodiment of this application, the vehicle body 20 includes an engine compartment, a sunshade and heat insulation device 10 is installed in the engine compartment, and an air cushion 11 is located in the engine compartment when it is in a retracted state; when the air cushion 11 is in an unfolded state, it extends at least partially from the engine compartment and covers the windshield 12 of the vehicle body 20.

[0082] Optionally, the air cushion 11 can cover the windshield 12, side windows, and rear window of the vehicle body 20.

[0083] The following is a detailed description of the installation of the sunshade and heat insulation device 10 in the engine compartment, specifically the body body 20 and the assembly of the body body 20 with the sunshade and heat insulation device 10:

[0084] Combination Figure 7 As shown, the vehicle body 20 also includes a frame and an engine compartment cover 21. The engine compartment is located inside the frame and can be used to install the sunshade and heat insulation device 10 and other vehicle components such as the engine or motor, excluding the sunshade and heat insulation device 10. The engine compartment cover 21 is connected to the frame and can cover or open the engine compartment.

[0085] Furthermore, combined Figures 8 to 9As shown, the engine compartment cover 21 includes a main cover 211 and a secondary cover 212, which together seal or open the engine compartment.

[0086] In this embodiment, the main cover 211 has a closed position and an open position. When the main cover 211 is in the open position, at least a portion of the engine compartment is opened to facilitate the repair or replacement of the engine and other vehicle parts. When the main cover 211 is in the closed position, at least a portion of the engine compartment is closed to cover the engine and other vehicle parts.

[0087] Correspondingly, the secondary cover 212 also has a closed position and an open position. When the secondary cover 212 is in the open position, at least part of the engine compartment is opened so that the air cushion 11 of the sunshade and heat insulation device 10 can extend from the engine compartment, thereby realizing the air cushion 11 switching from the retracted state to the unfolded state. When the secondary cover 212 is in the closed position, the secondary cover 212 and the main cover 211 together cover the engine compartment and cover the sunshade and heat insulation device 10 inside the engine compartment. This improves the aesthetics while preventing the sunshade and heat insulation device 10 from being placed outside the engine compartment cover 21, thereby increasing the wind resistance coefficient during driving.

[0088] In addition, the main body 20 may also include a drive motor, which is connected to the secondary cover 212, thereby enabling the secondary cover 212 to automatically switch between the closed position and the open position with one key.

[0089] It should be understood that the main cover 211 and the secondary cover 212 can move asynchronously. That is, when the main cover 211 is in the closed position, the secondary cover 212 can be in the open position; when the main cover 211 is in the open position, the secondary cover 212 can be in the closed position. Therefore, while ensuring that the sunshade and heat insulation device 10 can be concealed and stored, it is also possible to ensure that the air cushion 11 of the sunshade and heat insulation device 10 will not open the entire engine compartment when it is in the deployed state, thereby preventing other vehicle components such as the engine from being affected when the air cushion 11 is in the deployed state.

[0090] For example, combined Figure 10 As shown, the main cover 211 can also be hinged to the secondary cover 212 via a hinge 213. Of course, the main cover 211 can be hinged to the vehicle frame via the hinge 213, and the secondary cover 212 can also be hinged to the vehicle frame via the hinge 213. Both the main cover 211 and the secondary cover 212 can be flipped along the height direction of the vehicle to open or close the engine compartment.

[0091] In this embodiment, combined with Figure 11As shown, the vehicle body 20 also includes a first positioning structure 22 connected to the secondary cover 212. When the secondary cover 212 is in the open position, it can be connected between the frame and the secondary cover 212 through the first positioning structure 22 to position the secondary cover 212 in the open position.

[0092] For example, the first positioning structure 22 can be a movable hook rod, which is movably connected to the secondary cover 212. A positioning ring is provided on the part of the frame facing the secondary cover 212. When the secondary cover 212 is in the open position, the position of the movable hook rod can be changed so that the hook part of the movable hook rod connects with the positioning ring of the frame, and the secondary cover 212 is supported by the connecting rod of the movable hook rod, so that the secondary cover 212 can always be kept in the open position. In addition, when the secondary cover 212 is in the closed position, the movable hook rod can also change its position again and engage with the inner side of the secondary cover 212 facing the engine compartment. Finally, when the secondary cover 212 closes the engine compartment, the movable hook rod is also closed inside the engine compartment.

[0093] Furthermore, combined Figure 12 As shown, the vehicle body 20 also includes a second positioning structure 23 connected to the frame. When the secondary cover 212 is in the closed position, it can be connected to the main cover 211 through the second positioning structure 23 to position the secondary cover 212.

[0094] For example, the second positioning structure 23 can be an elastic snap-fit ​​structure, which includes a slot and a block. One of the two is disposed on the secondary cover 212 and the other is disposed on the main cover 211. The two work together to fix the secondary cover 212 in the closed position.

[0095] Of course, in other embodiments, when the secondary cover 212 is in the closed position, it can also be positioned in the closed position directly by its own gravity.

[0096] In this embodiment, the sunshade and heat insulation device 10 is located directly below the secondary cover 212 so that the air cushion 11 of the sunshade and heat insulation device 10 can be more easily extended from the engine compartment.

[0097] For example, the main cover 211, the secondary cover 212 and the windshield 12 are arranged sequentially along the wheelbase direction of the vehicle.

[0098] It should be understood that the secondary cover 212 is closer to the windshield 12 than the main cover 211.

[0099] In this embodiment, combined with Figure 8 and Figure 9As shown, the engine compartment can be divided into a main compartment 201a and a sub-compartment 201b by a partition 214. The main compartment 201a is used to house other vehicle components, such as the engine, except for the sunshade and heat insulation device 10, while the sub-compartment 201b is used to house the sunshade and heat insulation device 10, thereby avoiding interference between the sunshade and heat insulation device 10 and other vehicle components such as the engine.

[0100] It should be understood that when the engine compartment includes the main compartment 201a and the sub-compartment 201b, the main cover 211 can be used to cover or open the main compartment 201a, and the secondary cover 212 can be used to cover or open the sub-compartment 201b, thereby preventing dust, moisture and other impurities from entering the main compartment 201a after the sub-compartment 201b is opened, so as to affect the engine and other vehicle components in the main compartment 201a.

[0101] In this embodiment, the vehicle includes a temperature sensor (not shown), which is located in the cabin of the vehicle body 20, thereby monitoring the temperature in the cabin in real time.

[0102] It should be understood that the sunshade and heat insulation device 10 can operate based on the temperature inside the cabin monitored by the temperature sensor. For example, after the temperature sensor detects that the temperature inside the cabin exceeds a preset value, it controls the air cushion 11 of the sunshade and heat insulation device 10 to open the exhaust port 101 and simultaneously inflate the air cushion 11 to achieve air circulation inside the air cushion 11.

[0103] In another embodiment of this application, combined with Figure 6 As shown, the vehicle body 20 includes a rear luggage compartment, a sunshade and heat insulation device 10 is installed in the rear luggage compartment, and an air cushion 11 is located in the rear luggage compartment when it is in the retracted state; when the air cushion 11 is in the deployed state, at least part of it extends out from the rear luggage compartment and covers the windshield 12 of the vehicle body 20.

[0104] Optionally, the air cushion 11 can cover the windshield 12, side windows, and rear window of the vehicle body 20.

[0105] The following is a detailed description of the installation of the sunshade and heat insulation device 10 in the rear trunk, and the specific assembly of the vehicle body 20 and the sunshade and heat insulation device 10:

[0106] In this embodiment, the vehicle body 20 also includes a frame and a tailgate 31. The tailgate is located inside the frame and can be used to store the sunshade and heat insulation device 10 and luggage other than the sunshade and heat insulation device 10. The tailgate 31 is connected to the frame and can close or open the tailgate.

[0107] Furthermore, the tailgate cover 31 includes a female cover and a female cover, which together seal or open the tailgate.

[0108] In this embodiment, the cover has a closed position and an open position. When the cover is in the open position, at least a portion of the rear luggage compartment is opened to facilitate the storage of luggage. When the cover is in the closed position, at least a portion of the rear luggage compartment is closed to cover other vehicle components such as the engine.

[0109] Correspondingly, the sub-cover also has a closed position and an open position. When the sub-cover is in the open position, at least part of the rear trunk is opened so that the air cushion 11 of the sunshade and heat insulation device 10 can extend from the rear trunk, thereby switching the air cushion 11 from the rolled-up state to the unfolded state. When the sub-cover is in the closed position, the sub-cover and the main cover together cover the rear trunk and seal the sunshade and heat insulation device 10 inside the rear trunk. This improves the aesthetics while preventing the sunshade and heat insulation device 10 from being placed above the trunk lid 31, thereby increasing the wind resistance coefficient during driving.

[0110] It should be understood that when the main cover is in the closed position, the main cover and the secondary cover can move asynchronously. That is, when the main cover is in the closed position, the secondary cover can be in the open position. Therefore, while ensuring that the sunshade and heat insulation device 10 can be hidden and stored, it is also possible to ensure that the air cushion 11 of the sunshade and heat insulation device 10 will not open the entire rear luggage compartment when it is in the deployed state, thereby preventing luggage other than the sunshade and heat insulation device 10 from being affected when the air cushion 11 is in the deployed state.

[0111] For example, the main cover can be hinged to the rear of the frame via hinge 213, and the secondary cover can also be hinged to the rear of the frame via hinge 213. Both the main cover and the secondary cover can be flipped along the height of the vehicle to open or close the rear luggage compartment. Of course, the secondary cover can also be movably hinged to the main cover via hinge 213 (for example, the main cover has a through slot that connects to the rear luggage compartment, and after the secondary cover is connected to the main cover, it can rotate relative to the main cover to close or open the through slot).

[0112] In this embodiment, the vehicle body 20 also includes a first positioning structure 22 connected to the sub-cover. When the sub-cover is in the open position, it can be connected between the vehicle frame and the sub-cover through the first positioning structure 22 to position the sub-cover in the open position.

[0113] For example, the first positioning structure 22 can be a movable hook rod, which is movably connected to the sub-cover. A positioning ring is provided on the part of the frame facing the sub-cover. When the sub-cover is in the open position, the position of the movable hook rod can be changed so that the hook part of the movable hook rod connects with the positioning ring of the frame, and the sub-cover is supported by the connecting rod of the movable hook rod, so that the sub-cover can always be kept in the open position. In addition, when the sub-cover is in the closed position, the movable hook rod can also change its position again and snap onto the inner side of the sub-cover facing the rear luggage compartment. Finally, when the sub-cover closes the rear luggage compartment, the movable hook rod is also closed inside the rear luggage compartment.

[0114] Furthermore, the vehicle body 20 also includes a second positioning structure 23 connected to the frame. When the sub-cover is in the closed position, the second positioning structure 23 can be connected between the frame and the sub-cover to position the sub-cover in the closed position.

[0115] For example, the second positioning structure 23 can be an elastic snap-fit ​​structure, which includes a slot and a block. One of the two is disposed on the sub-cover, and the other is disposed on the part of the frame facing the sub-cover. The two work together to fix the sub-cover in the closed position.

[0116] Of course, in other embodiments, when the sub-cover is in the closed position, it can also be positioned in the closed position directly by its own gravity.

[0117] In this embodiment, the sunshade and heat insulation device 10 is located directly below the sub-cover, so that the air cushion 11 of the sunshade and heat insulation device 10 can more easily extend from the rear luggage compartment.

[0118] In this embodiment, the rear luggage compartment can be divided into a main compartment and a secondary compartment by a partition 214. The main compartment is used to store other vehicle components such as the engine, excluding the sunshade and heat insulation device 10, while the secondary compartment is used to store the sunshade and heat insulation device 10, thereby avoiding interference between the sunshade and heat insulation device 10 and other vehicle components such as the engine.

[0119] It should be understood that when the rear luggage compartment includes a main compartment and a secondary compartment, the main cover can be used to close or open the main compartment, and the secondary cover can be used to close or open the secondary compartment, thereby preventing dust, moisture and other impurities from entering the main compartment after the secondary compartment is opened, so as to avoid affecting the luggage inside the main compartment.

[0120] In this embodiment, the vehicle includes a temperature sensor (not shown) located inside the passenger compartment of the vehicle body 20, thereby monitoring the temperature inside the passenger compartment in real time.

[0121] It should be understood that the sunshade and heat insulation device 10 can operate based on the temperature inside the cabin monitored by the temperature sensor. For example, after the temperature sensor detects that the temperature inside the cabin exceeds a preset value, it controls the air cushion 11 of the sunshade and heat insulation device 10 to open the exhaust port 101 and simultaneously inflate the air cushion 11 to achieve air circulation inside the air cushion 11.

[0122] This embodiment also provides a control method for a sunshade and heat insulation device, which is applied to the sunshade and heat insulation device described above.

[0123] In this embodiment, the sunshade and heat insulation device 10 is connected to the vehicle's central control system via wiring, and the central control system controls the operation of the sunshade and heat insulation device 10.

[0124] For example, the sunshade and heat insulation device 10 is connected to an integrated circuit board. This integrated circuit board is responsible for powering the sunshade and heat insulation device 10, reading the status of the drive motor 161, the roller, the air cushion 11, the pressure sensor 17, and the exhaust port 101, and converting them into electrical signals that are transmitted to the MCU (Microcontroller Unit). At the same time, the MCU also transmits control information for the sunshade and heat insulation device 10 to the integrated circuit board, which then controls the operation of the sunshade and heat insulation device 10. The MCU is connected to the vehicle's central control system and is responsible for exchanging data with the central control system.

[0125] Optionally, physical buttons can be installed on the center console to control the operation of the entire sunshade and heat insulation device 10. The physical buttons can be located below the steering wheel or the center console screen for user convenience.

[0126] Optionally, the operation of the entire device can be controlled via vehicle control and equipment on the central control screen in the cockpit. When the user presses the power button, a signal is transmitted to the MCU, which then transmits the signal to the integrated circuit board, which controls the operation of the sunshade and heat insulation device 10.

[0127] Optionally, the entire sunshade and heat insulation device 10 can be controlled via a car owner's app by connecting the cockpit system to the cloud. The car owner sends operation commands to the cloud server through the app. After receiving the command, the cloud server locates the target vehicle and forwards the command to the target vehicle's cockpit system. The cockpit system is connected to the MCU and forwards the command to the MCU. The MCU transmits the signal to the integrated circuit board, which controls the operation of the sunshade and heat insulation device 10.

[0128] The following is a detailed introduction to the control methods for sunshade and heat insulation devices. The control methods include:

[0129] When the sunshade and heat insulation device receives a sunshade command, it controls the air cushion 11 to switch from the retracted state to the unfolded state so as to at least cover the windshield 12; and controls the air pump device 14 to inflate the air cushion 11.

[0130] It should be understood that when the sunshade and heat insulation device receives a sunshade command, it must first switch the secondary cover 212 to the open position to open part of the engine compartment; or, it must first control the sub-cover to the open position to open part of the rear luggage compartment before it can control the air cushion 11 to extend out of the engine compartment or the rear luggage compartment, thereby causing the air cushion 11 to switch from the retracted state to the deployed state.

[0131] Furthermore, after the air cushion 11 switches from the retracted state to the unfolded state, the air pump device 14 is controlled to inflate the air cushion 11 to facilitate airflow when the air pump device 14 inflates the air cushion 11.

[0132] It should be understood that once the central control system detects that the air cushion 11 has switched from the retracted state to the unfolded state, it can automatically control the air pump device 14 to inflate the air cushion 11.

[0133] In this embodiment, the central control system can use optical sensors to obtain the light intensity value inside the cabin to determine whether the air cushion 11 has switched from the retracted state to the deployed state.

[0134] For example, the central control system can be set to set the light intensity value inside the cabin to 'a' when the air cushion 11 is in the deployed state. If the optical sensor detects a light intensity value inside the cabin, the central control system can determine that the air cushion 11 has switched from the retracted state to the deployed state. If the optical sensor detects a light intensity value inside the cabin that is less than 'a', the central control system can determine that the air cushion 11 is still in the retracted state or in the process of switching from the retracted state to the deployed state.

[0135] Of course, in other embodiments, the air pump device 14 can be controlled to inflate the air cushion 11 while the air cushion 11 is switching from the rolled-up state to the unfolded state.

[0136] Furthermore, when the sunshade and heat insulation device 10 is equipped with a guide structure, the first and second telescopic rods can be extended simultaneously with the drive device driving the rotating shaft 163 to rotate, thereby pushing the guide rod to move and pull the air cushion 11 to at least cover the windshield 12, thus eliminating the need for the user to manually pull the air cushion 11 and cover the windshield 12. Of course, if the sunshade and heat insulation device 10 is not equipped with a guide structure, the user can also manually pull the air cushion 11 and cover the windshield 12 before fixing the air cushion 11 to the vehicle body 20.

[0137] Combination Figure 13 As shown, the pressure value inside the air cushion 11 is obtained by the pressure sensor 17, so as to determine whether the air cushion 11 has been fully inflated. If it has been fully inflated, the air pump device 14 is controlled to stop inflating the air cushion 11 and seal the air cushion 11 to make it in a sealed state.

[0138] In this embodiment, the pressure value inside the air cushion 11 is obtained by the pressure sensor 17, and the pressure value obtained by the pressure sensor 17 is transmitted to the central control system for data processing and issuing the next corresponding instruction.

[0139] Furthermore, if the pressure sensor 17 detects that the pressure value inside the air cushion 11 is less than the first preset pressure value, the central control system controls the air pump device 14 to inflate the air cushion 11. If the pressure sensor 17 detects that the pressure value inside the air cushion 11 is greater than or equal to the first preset pressure value, the central control system controls the air pump device 14 to stop inflating the air cushion 11.

[0140] For example, the first preset pressure value is 80% of the maximum pressure value that the air cushion 11 can withstand, thereby ensuring that the air cushion 11 can insulate heat after inflation, while also ensuring that the air cushion 11 will not expand and rupture.

[0141] It should be understood that after the central control system controls the air pump device 14 to inflate the air cushion 11 to a pressure exceeding the first preset value for the first time, the pressure sensor 17 will continue to acquire the pressure value inside the air cushion 11 and transmit the acquired pressure value inside the air cushion 11 to the central control system for data processing. That is to say, even after the air cushion 11 has been initially inflated, as long as the pressure value of the air cushion 11 is less than the first preset pressure value, the central control system can control the air pump device 14 to inflate the air cushion 11 again until the pressure value inside the air cushion 11 is not lower than the first preset pressure value and is less than the second preset pressure value. At this point, the inflation of the air cushion 11 is complete.

[0142] In some embodiments, if it is not guaranteed that the air inside the air cushion 11 is always in a circulating state, the exhaust port 101 of the air cushion 11 may not be closed. This allows the air pump device 14 to inflate the air cushion 11 to a pressure greater than or equal to the first preset pressure value, then stop inflating. After the pressure inside the air cushion 11 drops to less than the first preset pressure value, the air pump device 14 inflates the air cushion 11 again to a pressure greater than or equal to the first preset pressure value. This cycle is repeated to ensure that the air inside the air cushion 11 is always in a circulating state.

[0143] In this embodiment, if the pressure value inside the air cushion 11 exceeds the first preset pressure value and is equal to or greater than the second preset pressure value, the air cushion 11 is controlled to open its exhaust port 101 to vent air from the air cushion 11; or, the air pump device 14 is controlled to suck air into the air cushion 11 until the pressure value inside the air cushion 11 is greater than or equal to the first preset pressure value and less than the second preset pressure value. At this time, the inflation of the air cushion 11 is completed.

[0144] For example, the second preset pressure value is the maximum pressure value that the air cushion 11 can withstand, or 98% of the maximum pressure value that the air cushion 11 can withstand.

[0145] It should be understood that if, during or after inflation, the air cushion 11 is affected by other external factors (such as temperature, inflation accuracy, etc.) and causes the pressure inside the air cushion 11 to exceed the first preset pressure value and be equal to or greater than the second preset pressure value, some air needs to be released until the pressure inside the air cushion 11 is not lower than the first preset pressure value and is less than the second preset pressure value, thereby ensuring the safety of the air cushion 11.

[0146] Furthermore, combined Figure 14 As shown, when the air cushion 11 is in the deployed state, the temperature value of the vehicle can also be obtained, and the air cushion 11 can be controlled to open the exhaust port 101 according to the temperature value of the vehicle, and the air pump device 14 can be controlled to inflate the air cushion 11 accordingly.

[0147] For example, a temperature sensor can be installed in the vehicle's cabin to obtain the temperature value inside the cabin, and then the obtained temperature value is transmitted to the central control system, which processes the obtained temperature value to issue corresponding instructions.

[0148] Of course, in other embodiments, a temperature sensor can be directly installed inside the air cushion 11 to directly obtain the temperature value inside the air cushion 11, and then transmit the obtained temperature value to the central control system. The central control system processes the obtained temperature value to determine the temperature value of the vehicle and issue corresponding instructions.

[0149] In this embodiment, if the temperature inside the vehicle cabin exceeds the first preset temperature value, the air cushion 11 is controlled to open its exhaust port 101 to exhaust air from the air cushion 11.

[0150] For example, the first preset temperature value is 40°C.

[0151] In this embodiment, when the temperature inside the vehicle cabin exceeds the first preset temperature value, the air cushion 11 is controlled to open its exhaust port 101, and the air pump device 14 is controlled to inflate the air cushion 11, thereby realizing air circulation inside the air cushion 11; that is, the air cushion 11 can be inflated without waiting for the air cushion 11 to completely discharge the original gas.

[0152] Of course, in other embodiments, you can wait for the air cushion 11 to completely release the original gas before inflating the air cushion 11, thereby avoiding the original gas from mixing with the gas newly entering the air cushion 11 and causing the gas newly entering the air cushion 11 to heat up rapidly.

[0153] It should be understood that after the air cushion 11 opens its exhaust port 101, the pressure value inside the air cushion 11 continues to decrease. When the pressure sensor 17 detects that the pressure value inside the air cushion 11 has dropped to less than the first preset pressure value, it will feed back the pressure value at this time to the central control system and control the air pump device 14 to inflate the air cushion 11 through the central control system.

[0154] In this embodiment, the volume of gas discharged by the air cushion 11 through the exhaust port 101 per unit time can be slightly larger than the volume of gas pump 14 inflating the air cushion 11 per unit time.

[0155] In this embodiment, if the temperature inside the vehicle's cabin is lower than the first preset temperature value, the air cushion 11 is controlled to close its exhaust port 101, and the pressure value inside the air cushion 11 and the temperature value inside the vehicle's cabin are continuously acquired.

[0156] In this embodiment, before the temperature inside the vehicle's cabin exceeds a first preset temperature value, the air cushion 11 can be continuously inflated while simultaneously deflating it. This rapidly removes heat from the air cushion 11 and the surrounding environment of the vehicle, thereby lowering the vehicle's temperature until it falls below the first preset temperature value. Then, the air cushion 11 closes its exhaust port 101. After the air cushion 11 closes its exhaust port 101, the air pump device 14 continues to inflate the air cushion 11 until the pressure inside the air cushion 11 exceeds or equals the first preset pressure value. At this point, the air pump device 14 stops inflating the air cushion 11.

[0157] It should be understood that when the air cushion 11 is in the deployed state, the temperature sensor will continuously acquire the temperature value of the vehicle. As long as the temperature value of the vehicle exceeds the first preset temperature value, the air cushion 11 will be controlled to open its exhaust port 101 to exhaust air from the air cushion 11. If the temperature value of the vehicle is less than the first preset temperature value, the air cushion 11 will be controlled to close its exhaust port 101.

[0158] In addition, an alarm device can be installed inside the air cushion 11. This alarm device can be connected to the vehicle's infotainment system, allowing warning messages to be transmitted to the user's mobile phone or other electronic devices. For example, if the air cushion 11 is exposed to direct sunlight for too long, and the temperature inside the cabin is detected by the vehicle's temperature sensor, indicating that the air cushion 11 is about to reach the critical temperature for spontaneous combustion, the alarm device can send a warning message to the vehicle owner, prompting the owner to issue a retraction command for the air cushion, or sound an alarm to attract the attention of passersby, thereby preventing a fire.

[0159] Furthermore, when the air cushion 11 is in the deployed state and the vehicle receives a retraction command, the air cushion 11 is controlled to open the exhaust port 101, and / or the air pump device 14 is controlled to draw air into the air cushion 11.

[0160] It should be understood that when the air cushion 11 needs to switch from the unfolded state to the retracted state, if only the exhaust port 101 of the air cushion 11 is opened, the air cushion 11 will exhaust slowly and not completely. Therefore, the air pump device 14 can also be controlled to suck air into the air cushion 11 at the same time to quickly and cleanly exhaust the air inside the air cushion 11, thereby facilitating the storage of the air cushion 11.

[0161] In this embodiment, controlling the air pump device 14 to suck air from the air cushion 11 includes: obtaining the pressure value inside the air cushion 11; if the pressure value inside the air cushion 11 is less than a third preset pressure value, then controlling the air pump device 14 to stop sucking air from the air cushion 11.

[0162] Furthermore, the third preset pressure value is less than the first preset pressure value.

[0163] For example, the third preset pressure value is 50% of the maximum pressure that the air cushion 11 can withstand.

[0164] It should be understood that when the air cushion 11 first opens the exhaust port 101, the exhaust rate is relatively fast, and it is not necessary to use the air pump device 14 to suck air into the air cushion 11. However, as the gas in the air cushion 11 decreases and the air pressure value decreases, the exhaust rate of the air cushion 11 gradually decreases. At this time, the air pump device 14 can be used to suck air into the air cushion 11 to assist in the exhaust of the air cushion 11.

[0165] In addition, when the sunshade and heat insulation device receives a sunshade command and rolls up the air cushion 11 in the engine compartment or the trunk, the vehicle must first control the secondary cover 212 to switch from the open position to the closed position to close part of the engine compartment, thereby concealing the entire sunshade and heat insulation device 10 inside the engine compartment; or, the sub-cover must first control the sub-cover to switch from the open position to the closed position to close part of the trunk, thereby concealing the entire sunshade and heat insulation device 10 inside the trunk.

[0166] The above content is merely a preferred exemplary embodiment of this application and is not intended to limit the implementation of this application. Those skilled in the art can easily make corresponding modifications or alterations based on the main concept and spirit of this application. Therefore, the scope of protection of this application should be determined by the scope of protection claimed in the claims.
