For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0034] With the development of the automotive industry, consumers' demands for vehicle comfort are gradually increasing. In cold climates, weatherstripping is prone to hardening due to low temperatures. Taking car doors as an example, the hardening of weatherstripping at low temperatures leads to a decrease in sealing performance, which not only affects the normal opening and closing of the doors, but also causes driving problems such as cold feet, poor air conditioning heating effect, and poor range, thus affecting the comfort of the vehicle.

[0035] Among related technologies, one method involves heating the door sealing strip by adding heating wires to improve the door's sealing performance. However, this electric heating method suffers from high energy consumption, complex structure, and high maintenance costs. Furthermore, it primarily focuses on defrosting the door, limiting its application scenarios.

[0036] like Figure 1As shown, according to a first aspect embodiment of the present invention, the sealing strip 10 includes a sealing strip body 11, and a heat exchange channel 12 is provided in the sealing strip body 11. The heat exchange channel 12 is used to introduce a heat exchange medium, which is used to heat the sealing strip body 11.

[0037] Specifically, the sealing strip body 11 has a heat exchange channel 12 inside, which can introduce the external heat exchange medium into the sealing strip body 11 and heat the sealing strip body 11 through heat exchange to ensure its sealing performance.

[0038] In cold climates, the sealing strip 10 hardens due to low temperature, resulting in a decrease in sealing performance. Warm air can be used as a heat exchange medium. It enters the sealing strip body 11 through the heat exchange channel 12 inside the sealing strip body 11. The warm air exchanges heat with the sealing strip body 11, heating the hardened sealing strip body 11, softening it, restoring the sealing performance of the sealing strip 10, and improving the sealing effect.

[0039] According to some embodiments of the present invention, a first cavity 13 is also formed inside the sealing strip body 11, and the first cavity 13 is not in communication with the heat exchange channel 12.

[0040] like Figure 1 As shown, the sealing strip 10 also forms a first cavity 13. The first cavity 13 is used to deform when the sealing strip 10 is subjected to force, so that the sealing strip 10 has a better elastic deformation ability. The first cavity 13 is not connected to the heat exchange channel 12 to prevent the heat exchange medium in the heat exchange channel 12 from leaking and affecting the heat exchange effect.

[0041] In some optional embodiments, the first cavity 13 is formed on the outside of the heat exchange channel 12. For example, when the outermost contour of the sealing strip body 11 is circular, the cross-section of the heat exchange channel 12 is elliptical. The specific dimensions of the heat exchange channel 12 can be adjusted by comprehensively considering the sealing strip body 11, the heat exchange medium conveying pipeline, and the structural characteristics of the component to be sealed.

[0042] In some optional embodiments, the sealing strip body 11 is provided with a plurality of vent holes, which are connected to the first cavity 13 and are used to discharge the gas in the first cavity 13 when the sealing strip 10 is deformed by external force.

[0043] In some optional embodiments, the sealing strip body 11 is provided with mounting holes 14 for fixing the sealing strip 10 to the component to be sealed, thereby ensuring its reliability.

[0044] like Figure 2As shown, the sealing strip 10 heating system according to the second aspect embodiment of the present invention is applied to a vehicle. The sealing strip 10 heating system includes the sealing strip 10 of the first aspect embodiment, a heat exchange device, the heat exchange device being connected to the heat exchange channel 12 via a pipe assembly, and the heat exchange device being used to heat the heat exchange medium.

[0045] Specifically, the sealing strip 10 heating system according to an embodiment of the present invention is applied to a vehicle. The sealing strip 10 heating system can transport the heat exchange medium heated by the heat exchange device to the heat exchange channel 12 of the sealing strip body 11 through the pipeline assembly, so that the heated heat exchange medium exchanges heat with the sealing strip body 11, heats and softens the sealing strip 10, ensures the sealing performance of the sealing strip 10, enhances the sealing performance of the vehicle, and improves the comfort of the vehicle user.

[0046] According to some embodiments of the present invention, the heat exchange device includes an air conditioning module of a vehicle, which is connected to the heat exchange channel 12 via a pipe assembly.

[0047] like Figure 2 As shown, existing vehicle air conditioning modules can heat the air, raising the temperature of the passenger compartment and ensuring passenger comfort in cold climates. Some embodiments of the present invention directly use the heat exchange medium heated by the existing vehicle air conditioning module, and through a pipe assembly diversion design, directly input the air conditioning warm air into the sealing strip body 11 to heat the sealing strip body 11 and ensure its sealing performance.

[0048] Compared to vehicles without a sealing strip heating system, the sealing strip 10 heating system provided in some embodiments of the present invention can ensure that the air conditioning heating air is directly and efficiently input into the sealing strip 10, achieving a rapid heating effect. At the same time, because the channel is independent, the heating air is not interfered with by other components or spaces during transmission, thereby reducing heat loss.

[0049] Compared to existing electric heating methods, the sealing strip 10 heating system provided in some embodiments of the present invention is based on the vehicle's existing air conditioning and heating system. Through the air duct diversion design, it does not require additional heating elements or complex control systems, which greatly reduces production costs and installation difficulty.

[0050] According to some embodiments of the present invention, the pipe assembly includes a first pipe 21 connected between the inlet of the heat exchange channel 12 and the warm air pipe 23 of the air conditioning module; the pipe assembly also includes a second pipe 22 connected between the outlet of the heat exchange channel 12 and the air outlet 27 of the air conditioning module.

[0051] like Figure 2As shown, after the warm air is output from the heating duct 23 of the air conditioning module, it passes through the first duct 21, the heat exchange channel 12, and the second duct 22 before being output from the air outlet 27 of the air conditioning module, realizing the flow and transfer of heat energy, so that the sealing strip 10 can be continuously in the heating mode.

[0052] like Figure 1-2 As shown, in some optional embodiments, an opening is made at or near the end of the sealing strip body 11 to connect to the first pipe 21, allowing the warm air from the vehicle's air conditioning module to flow directly through the heat exchange channel 12 inside the sealing strip 10 after passing through the first pipe 21, and to contact the inner wall of the sealing strip body 11 to achieve heat exchange, thereby improving heat transfer efficiency, heating and softening the sealing strip 10, and improving sealing performance. Furthermore, an opening is made at or near the other end of the sealing strip body 11 to connect to the second pipe 22, allowing the warm air from the vehicle's air conditioning module to flow through the sealing strip 10, pass through the second pipe 22, and then be discharged from the air outlet 27 of the air conditioner, thus achieving heat transfer.

[0053] In some optional embodiments, the heat exchange channel 12 inside the sealing strip body 11 can be designed separately from the sealing strip 10. The heat exchange channel 12 can be made of a material with good thermal conductivity to conduct the heat of the warm air into the sealing strip 10, thereby softening the sealing strip body 11. At the same time, multiple holes can be opened on the outer wall of the heat exchange channel 12 so that the warm air flowing through the heat exchange channel 12 will be output through multiple holes and directly contact the inner wall of the sealing strip body 11 to heat and soften the sealing strip body 11. However, it is necessary to ensure the sealing of the end of the sealing strip 10 to prevent the warm air from escaping from the end of the sealing strip 10. In addition, when the heat exchange channel 12 inside the sealing strip body 11 is designed separately from the sealing strip 10, the first pipe 21, the heat exchange channel 12 and the second pipe 22 can be made of different heat-conducting materials and can be separately or integrally formed to ensure the smooth flow and transfer of heat energy.

[0054] In some optional embodiments, the air conditioning heating duct 23 is connected to the air conditioner blower. After passing through the first duct 21, the warm air enters the inlet of the heat exchange channel 12, heats the sealing strip body 11, and is then output from the outlet of the heat exchange channel 12. After passing through the second duct 22, it is discharged into the vehicle's interior space from the vehicle's existing air conditioning vent 27, thus realizing the circulation and transfer of heat energy.

[0055] In some alternative embodiments, such as Figure 2 As shown, when the sealing strip 10 heating system is applied to the left front door of a vehicle, the end of the second pipe 22 away from the heat exchange channel 12 can be connected to the air conditioning vent 27 in the vehicle that blows air onto the driver's feet, and finally guide the airflow into the vehicle interior space; an air conditioning vent 27 can also be added according to the specific location of the second pipe 22, or a separate outlet can be set to discharge the airflow after the heating sealing strip 10.

[0056] According to some embodiments of the present invention, the heating system of the sealing strip 10 further includes a connecting assembly for sequentially connecting the warm air duct 23, the first duct 21, the heat exchange channel 12, and the second duct 22.

[0057] Specifically, the heating air duct 23 and the first duct 21, the first duct 21 and the heat exchange channel 12, and the heat exchange channel 12 and the second duct 22 need to be fixedly connected by connecting components, which can be clamps, clips, etc. with screws. At the same time, the heating air duct 23, the first duct 21, the heat exchange channel 12, and the second duct 22 also need to be fixed to the corresponding positions on the vehicle body using connectors to ensure the stability of the entire system.

[0058] According to some embodiments of the present invention, the heating system of the sealing strip 10 further includes a gas regulating device 24, which is disposed between the pipe assembly and the heat exchange device.

[0059] like Figure 2 As shown, a gas regulating device 24 is installed between the pipe assembly and the heat exchange device to adjust the flow rate of warm air entering the sealing strip body 11 according to actual needs, so as to ensure the sealing effect of the sealing strip 10.

[0060] According to some embodiments of the present invention, the gas regulating device 24 includes at least one of a valve, a flow controller, and a booster.

[0061] like Figure 2 As shown, the gas regulating device 24 may include one or more of a valve, a flow controller, and a gas booster for precise control of the flow rate of warm air entering the sealing strip body 11, heating and softening the sealing strip 10 to ensure that the sealing strip 10 has the best sealing effect.

[0062] According to some embodiments of the present invention, at least a portion of the first pipe 21 and / or at least a portion of the second pipe 22 are made of a high-temperature resistant insulation material.

[0063] like Figure 2 As shown, a small portion of the first pipe 21 and the second pipe 22 are not inside the sealing strip 10. To ensure effective heat transfer, the portions of the first pipe 21 and the second pipe 22 outside the sealing strip body 11 are made of high-temperature resistant insulation material to reduce heat loss and ensure long-term stable operation of the sealing strip 10 during heating.

[0064] According to some embodiments of the present invention, the heating system of the sealing strip 10 further includes a first temperature sensor 25, which is disposed inside the sealing strip body 11 and is used to detect the temperature inside the sealing strip body 11. When the first temperature detected by the first temperature sensor 25 is less than the first temperature threshold, the sealing strip body 11 is heated.

[0065] like Figure 2-3 As shown, a high-precision first temperature sensor is installed inside the sealing strip body 11 to monitor the temperature of the heat exchange medium inside the sealing strip body 11 in real time. When the first temperature detected by the first temperature sensor 25 is less than the first temperature threshold, the sealing strip body 11 is heated to ensure that the heating process is carried out within the set temperature range and to ensure that the sealing strip 10 has the best sealing effect.

[0066] In some alternative embodiments, heating of the sealing strip body 11 is stopped when the first temperature detected by the first temperature sensor 25 is greater than or equal to the first temperature threshold.

[0067] According to some embodiments of the present invention, the first temperature sensor 25 is installed near the outlet area of ​​the heat exchange channel 12.

[0068] like Figure 2 As shown, since the temperature of the warm air in the first pipe 21 is relatively high, it will continue to exchange heat after entering the heat exchange channel 12 in the sealing strip body 11. This results in a relatively low temperature at the outlet of the heat exchange channel 12. The temperature at the outlet of the heat exchange channel 12 is the lowest temperature of the airflow in the entire sealing strip body 11. A first temperature sensor 25 is installed in the outlet area of ​​the heat exchange channel 12 to ensure the validity of the first temperature value detected by the first temperature sensor 25, so as to more accurately control the heating system of the sealing strip 10 and ensure the sealing effect.

[0069] In some optional embodiments, multiple first temperature sensors 25 may be installed inside the sealing strip body 11, and the minimum value of the first temperature detected by the multiple first temperature sensors 25 shall be used as the effective value for control to ensure the sealing effect of the entire sealing strip body 11.

[0070] According to some embodiments of the present invention, the heating system of the sealing strip 10 further includes a second temperature sensor 26, which is used to detect the external ambient temperature of the vehicle. When the second temperature detected by the second temperature sensor 26 is less than a second temperature threshold, the sealing strip body 11 is heated.

[0071] like Figure 3 As shown, the sealing strip 10 heating system monitors the external ambient temperature of the vehicle in real time through the second temperature sensor 26 in the detection module. When the second temperature detected by the second temperature sensor 26 is less than the second temperature threshold, the sealing strip body 11 is heated to ensure that the heating process is carried out within the set temperature range and to ensure that the sealing strip 10 has the best sealing effect.

[0072] In some alternative embodiments, the second temperature threshold ranges from -5°C to 0°C.

[0073] According to some embodiments of the present invention, the heating system of the sealing strip 10 further includes a control module, and the first temperature sensor 25 and the second temperature sensor 26 are both electrically connected to the control module.

[0074] like Figure 3 As shown, both the first temperature sensor 25 and the second temperature sensor 26 are connected to the control module, transmitting the internal temperature of the sealing strip body 11 and the external ambient temperature to the control module in real time. The control module controls the temperature of the sealing strip body 11 according to a preset algorithm to ensure the sealing performance of the sealing strip 10.

[0075] In some alternative embodiments, the first temperature sensor 25 and the second temperature sensor 26 are electrically connected to the control module wirelessly or via a wired connection.

[0076] According to some embodiments of the present invention, the heat exchange device includes a vehicle air conditioning module, and the control module is also electrically connected to the control unit of the air conditioning module for controlling the temperature of the heat exchange medium.

[0077] like Figure 3 As shown, the heating system of the sealing strip 10 can adjust the flow rate of warm air entering the heating system of the sealing strip 10 through the gas regulating device 24 based on the temperature inside the sealing strip body 11 fed back by the first temperature sensor 25 and the ambient temperature outside the vehicle fed back by the second temperature sensor 26; at the same time, the temperature of the warm air entering the heating system of the sealing strip 10 can be changed through the air conditioning device.

[0078] According to some embodiments of the present invention, the control module includes a display terminal, which includes an in-vehicle display terminal and / or a mobile display terminal.

[0079] like Figure 3 As shown, users can control the controller of the sealing strip 10 heating system control module through an in-vehicle display terminal, such as an in-vehicle central control screen, or remotely control the controller of the sealing strip 10 heating system control module through a mobile display terminal, such as a mobile phone terminal, to adjust the heating state of the sealing strip 10 and achieve intelligent regulation.

[0080] According to some embodiments of the present invention, the controller of the control module is integrated into the vehicle's overall controller. The integration of the controller of the sealing strip 10 heating system control module into the overall vehicle controller simplifies the structure of the entire system and saves space in the vehicle.

[0081] In some alternative embodiments, the controller of the heating system control module of the sealing strip 10 can also be integrated into the vehicle's domain controller, saving space in the vehicle.

[0082] In some optional embodiments, the control interface of the display terminal integrates operations such as turning the sealing strip 10 heating function on / off, selecting the heating mode, setting the temperature, and timer on / off. Specifically, when the sealing strip 10 heating system of this application is applied to the vehicle door 28, the controller of the sealing strip 10 heating system can preset multiple heating modes, including: Automatic temperature control mode: Automatically activated based on the ambient temperature outside the vehicle. For example, when the ambient temperature outside the vehicle, as indicated by the second temperature sensor 26, is lower than the second temperature threshold, the heating system of the sealing strip 10 automatically starts.

[0083] Manual control mode: Users can freely select one or more door seals 10 corresponding to the door 28 for heating, set the heating temperature, warm air volume, and heating duration according to their actual needs.

[0084] Priority allocation: The system prioritizes heating the door seals 28 and 10 of the driver and front passenger seats to ensure the comfort of the driver and front passenger.

[0085] Temperature Maintenance Mode: Maintains the temperature of the sealing strip 10 at the set value. The system is monitored in real-time by the first temperature sensor 25. When the temperature is below the first temperature threshold, the heating system of the sealing strip 10 is activated; when the temperature reaches or exceeds the first temperature threshold, the heating system of the sealing strip 10 is deactivated.

[0086] Timed preheating mode: Users set a specific time, at which time the door 28 sealing strip 10 will automatically start heating, ensuring that the door 28 is easy to open and well-sealed when getting into the vehicle. This mode can be used in conjunction with the vehicle's remote start function to preheat the sealing strip 10 and the vehicle interior in advance, facilitating preparation for winter use.

[0087] Energy-saving mode: While ensuring basic sealing performance, it reduces energy consumption by reducing heating power or intermittent heating. It is suitable for situations where the vehicle is parked for a long time but it is desirable to maintain a certain level of sealing of the vehicle's sealing strip 10.

[0088] Users can select different heating modes according to their softening needs for the sealing strip 10. For example, to improve vehicle sealing, users can select the temperature maintenance mode to keep the sealing strip 10 soft during driving and improve air leakage in the door 28. For the sealing strip 10 that needs to be softened quickly, users can manually increase the flow rate of warm air inside the sealing strip 10. For the sealing strip 10 that needs to be softened slowly, users can manually decrease the flow rate of warm air inside the sealing strip 10.

[0089] To facilitate understanding, the following explanation, based on the aforementioned sealing strip 10 and its heating system, will be provided in more detail with specific examples, such as... Figure 4 As shown, in an optional embodiment, the heating system of the sealing strip 10 of this application may include the following operating steps: S101: The control module receives the instruction and starts the heating system of the sealing strip 10.

[0090] Users can remotely activate and set the function via a smartphone application; or users can manually activate and set the function via the vehicle's central control screen; or after activating the automatic temperature control mode, when the vehicle is in a low-temperature environment, the sealing strip 10 heating system control module determines whether the sealing strip 10 heating system needs to be activated based on the ambient temperature, the internal temperature of the sealing strip body 11, and the set threshold; or after activating the timed preheating mode, the control module automatically activates the sealing strip 10 heating system at the scheduled time.

[0091] S102: Controls the vehicle's air conditioning module to deliver warm air to the heat exchange channel 12 inside the sealing strip body 11.

[0092] The control module of the heating system for the sealing strip 10 can control the temperature, airflow, and duration of the warm air delivered by the vehicle's air conditioning module to the heat exchange channel 12 of the sealing strip 10. After the warm air is delivered to the heat exchange channel 12 of the sealing strip 10, the heat rapidly heats the sealing strip body 11, achieving a softening and preheating effect. Simultaneously, by setting the heating mode to a temperature maintenance mode, the sealing strip 10 can be ensured to maintain its sealing performance in low-temperature environments, improving driving comfort and safety. The heating process can also be controlled through priority allocation mode and energy-saving mode settings.

[0093] S103: Obtain the real-time temperature of the internal temperature sensor of the sealing strip body 11 in the heating system of the sealing strip 10.

[0094] The temperature sensor inside the sealing strip body 11 monitors the temperature change inside the sealing strip body 11 in real time and feeds the data back to the control module.

[0095] S104: Determine whether the temperature in the heating system of the sealing strip 10 is greater than or equal to the preset temperature threshold.

[0096] The system determines whether the internal temperature of the sealing strip body 11 is greater than or equal to a first temperature threshold. If it is greater than or equal to the first temperature threshold, the heating system of the sealing strip 10 is turned off via the display terminal to save energy and extend the service life of the system. If it is less than the first temperature threshold, the control module adjusts the temperature and volume of the warm air delivered by the vehicle's air conditioning module according to the internal temperature value of the sealing strip body 11, so that the sealing strip 10 reaches the working temperature range of the preset mode.

[0097] According to a third aspect of the present invention, the door 28 includes a heating system for the sealing strip 10 according to a second aspect of the present invention.

[0098] Specifically, the heating system of the sealing strip 10 according to the second aspect embodiment of the present invention can be applied to the vehicle door 28, such as... Figure 2As shown, this system is applied to the left front door 28 of a vehicle. Multiple doors 28 can be equipped with this system at the same time and can be controlled independently of each other, which improves the phenomenon of hardening and air leakage of the door 28 sealing strip 10.
