For the parts required for the overall scheme implementation but not involved in the overall arrangement described above, reasonable and flexible design can be made by referring to the mature arrangement means in the field, the actual situation during implementation, etc. The specific implementation scheme described below in the present embodiment is only one of the relatively optimal schemes formed by various combinations and changes of the above, and in actual implementation, the person skilled in the art can make flexible adjustment and improvement in combination with the actual situation. Obviously, the various specific form combinations and changes of the above can form many schemes, and the specific implementation scheme of the present embodiment is within the protection scope of the present application.

[0052] In addition, the sealing strip 1 described above can be a sealing strip 1 on the front door or the rear door of the vehicle, or a sealing strip 1 on the back door. In the present embodiment, the front door and the rear door on one side of the vehicle are taken as examples, and one circulating pump assembly 2 is used to simultaneously control the heating of the front door sealing strip 11 and the rear door sealing strip 12.

[0053] As shown in Figure 2 , the sealing strip 1 of the present embodiment includes a mounting portion 10 for connecting the vehicle door and a sealing portion formed on the mounting portion 10, and a circulating channel 100 is arranged in the sealing portion. Of course, the sealing strip 1 described above can also adopt other structural forms. In the present embodiment, the sealing strip 1 is designed as two parts of the mounting portion 10 and the sealing portion on the cross section of the sealing strip 1, the sealing strip 1 can be conveniently mounted on the vehicle door by using the clamping structure arranged on the mounting portion 10, a cavity can be arranged in the inside of the mounting portion 10 to improve the deformation performance of the mounting portion 10 and reduce the overall weight of the sealing strip 1. The circulating channel 100 arranged in the sealing portion not only ensures that the circulating channel 100 has sufficient cross-sectional area to ensure the flow rate of the heating liquid, but also enables the sealing portion to have good deformation buffering performance after the heating liquid in the circulating channel 100 is emptied, thereby ensuring the sealing effect of the sealing portion.

[0054] The specific structure of the circulating pump assembly 2 can be designed according to existing mature hydraulic pumps. Preferably, the following specific structure is adopted. The circulating pump assembly 2 comprises a liquid inlet chamber 200, a pressurizing chamber 201, a liquid return chamber 202, a liquid discharge chamber 203, a liquid supply pump arranged between the liquid inlet chamber 200 and the pressurizing chamber 201, and a liquid discharge pump arranged between the liquid return chamber 202 and the liquid discharge chamber 203; the liquid inlet chamber 200 and the liquid storage device are connected by a liquid inlet pipeline 20, and the liquid discharge chamber 203 and the liquid storage device are connected by a liquid return pipeline 23; the pressurizing chamber 201 is connected with the sealing strip liquid inlet pipe 21 of the sealing strip 1; and the liquid return chamber 202 is connected with the sealing strip liquid discharge pipe 22 of the sealing strip 1.

[0055] The chambers such as the liquid inlet chamber 200, the pressurizing chamber 201, the liquid return chamber 202, and the liquid discharge chamber 203 are arranged in the circulating pump assembly 2, which not only facilitates the connection of the liquid inlet pipeline 20 and the liquid return pipeline 23 from the liquid storage device, and the sealing strip liquid inlet pipe 21 and the sealing strip liquid discharge pipe 22 of the sealing strip 1, but also provides space for accommodating and buffering the heating liquid; the liquid supply pump arranged between the liquid inlet chamber 200 and the pressurizing chamber 201 can increase the pressure of the heating liquid, thereby pumping the heating liquid into the circulating channel 100 of the sealing strip 1 to make the heating liquid circulate in the circulating channel 100; the liquid discharge pump arranged between the liquid return chamber 202 and the liquid discharge chamber 203 not only assists the liquid supply pump to improve the circulating flow effect of the heating liquid, but also can empty the heating liquid in the circulating channel 100 by means of the liquid discharge pump after the heating of the sealing strip 1 is completed, thereby maintaining the sealing and buffering effect of the sealing strip 1.

[0056] Of course, there are many different design schemes for the specific arrangement of the temperature regulation unit 5. Specifically, in the present embodiment, the temperature regulation unit 5 comprises a sealing system water circulation integrated control module 50, a signal acquisition device 51, a heating device 52, a circulating pump assembly 2, and a liquid storage device for storing the heating liquid. The signal acquisition device 51 is used to detect the temperature of the sealing strip 1, the heating device 52 is used to heat the heating liquid in the liquid storage device, and the sealing system water circulation integrated control module 50 receives the signal input from the signal acquisition device 51 and drives the heating liquid in the liquid storage device to circulate in the circulating channel 100 to increase the temperature of the sealing strip 1 to a set temperature range. The configuration of the functional components such as the sealing system water circulation integrated control module 50, the signal acquisition device 51, the heating device 52, and the circulating pump assembly 2 in the temperature regulation unit 5 can smoothly realize the functions of heating and circulating the heating liquid; through the temperature detection of the sealing strip 1 by the signal acquisition device 51, it can be known whether the freezing condition between the vehicle door and the door frame occurs, and the temperature regulation degree of the sealing strip 1 can be known in time; when the temperature of the sealing strip 1 is heated to a reasonable temperature range and maintained for a certain time, the frozen ice at the sealing strip 1 can be melted, thereby ensuring the ice melting effect of the automobile sealing temperature control system.

[0057] Of course, the signal acquisition device 51 described above can adopt various different configurations. In the embodiment, the signal acquisition device 51 comprises a temperature sensor arranged at the sealing strip 1, and a signal conversion module connected between the temperature sensor and the sealing system water circulation integrated control module 50; the signal conversion module converts the temperature signal detected by the temperature sensor into an analog signal and transmits the analog signal to the sealing system water circulation integrated control module 50, so that the system can control the temperature at the sealing strip 1 in real time.

[0058] In addition, the automobile sealing temperature control system of the embodiment further comprises a master control unit 3 and an automobile key 4; the temperature control unit 5 and the automobile key 4 are both connected to the master control unit 3, the master control unit 3 can receive the instruction signal of the automobile key 4 and control the temperature control unit 5 to control the temperature of the sealing strip 1. In order to improve the use experience and effect of the whole vehicle, the master control unit 3 is arranged in the automobile sealing temperature control system, and the automobile key 4 is connected to the automobile sealing temperature control system, so that a more perfect system architecture can be formed. Preferably, the master control unit 3 described above can be directly integrated into the main machine of the vehicle, the main machine is wirelessly connected to the automobile key 4, and the main machine and the temperature control unit 5 can be connected by a line. When the user operates the automobile key 4 to issue an opening instruction signal of the vehicle door, the master control unit 3 can control the temperature control unit 5 to perform the temperature control process of the sealing strip 1, so that the use experience of the system is better.

[0059] Based on the above arrangement, the automobile sealing temperature control system of the embodiment further comprises a man-machine interaction unit 31 connected to the master control unit 3; the man-machine interaction unit 31 is used to issue an instruction signal to the master control unit 3 and / or display the control state of the sealing strip 1. Specifically, the man-machine interaction unit 31 of the embodiment comprises a multimedia control module and a display assembly, the multimedia control module is responsible for the communication and signal conversion between the display assembly and the master control unit 3. The data provided by the master control unit 3 is displayed on the display assembly, and the parameter setting and operation instruction from the display assembly are accepted. By means of the man-machine interaction unit 31 such as the control screen of the vehicle, the control interface of the temperature control unit 5, the state of the sealing strip 1 being controlled by the temperature control unit 5, etc. can be displayed on the control screen, so that the user can better understand the current state of the sealing strip 1 and improve the convenience of operation; and the control parameters such as the temperature range described above can also be flexibly set.

[0060] In summary, the automobile sealing temperature control system of the embodiment, by arranging the circulation channel 100 in the sealing strip 1, under the control of the temperature control unit 5, using the circulating heating liquid to heat and control the temperature of the sealing strip 1, the part where the sealing strip 1 is located can be heated to a degree that the frozen ice is melted, so that the vehicle door can be opened smoothly, and the problem that the vehicle door cannot be opened in extremely cold weather conditions is solved.

[0061] Embodiment two

[0062] The embodiment relates to a control method for the automobile sealing temperature control system provided in the first embodiment. Figure 5 and Figure 6 as shown.

[0063] Overall, the control method of the embodiment comprises the following steps.

[0064] An opening instruction signal of the vehicle door is acquired, the automobile sealing temperature control system is powered on when the opening instruction signal is received, and the freezing condition of the sealing strip 1 is detected; when the freezing condition of the sealing strip 1 occurs, the temperature control unit 5 is controlled to regulate the temperature of the sealing strip 1.

[0065] After the opening instruction signal of the vehicle door is acquired, the automobile sealing temperature control system is powered on, so that the standby time of the automobile sealing temperature control system can be greatly reduced, thereby saving the power consumption of the automobile sealing temperature control system on the vehicle. When the freezing condition of the sealing strip 1 of the vehicle door is detected, the temperature control unit 5 is controlled to regulate the temperature of the sealing strip 1, so that the ice melting operation between the vehicle door and the door frame can be completed in a targeted manner, thereby providing conditions for the smooth opening of the vehicle door. Of course, there are many technical means for detecting the freezing condition of the sealing strip 1, for example, the temperature condition of the vehicle exterior and the length of time of the closed vehicle door can be comprehensively judged. In the embodiment, by arranging the temperature sensor at the sealing strip 1, the temperature of the sealing strip 1 can be understood by the temperature measured by the temperature sensor, and whether the sealing strip 1 of the vehicle door is frozen or the freezing condition is melted can be judged according to the temperature value.

[0066] Based on the overall control idea, the following indicative output setting is preferably performed. When it is detected that the freezing condition of the sealing strip 1 does not occur or is eliminated, a first indication signal is sent; when the temperature of the sealing strip 1 is regulated by the temperature control unit 5, a second indication signal is sent.

[0067] By setting the above steps, the current working state of the automobile sealing temperature control system can be known in time, and whether the freezing or the freezing elimination exists at the sealing strip 1 can be known, so that the user can know whether the door can be opened. Of course, the form of the indication signal can be reasonably set according to the habit of the user and the hardware configuration. In the embodiment, the automobile key 4 includes an output unit 40 and a feedback unit 41, wherein the output unit 40 includes a pressure sensor and a key integrated control module. After the user presses the operation trigger pressure sensor, the signal of the pressure sensor is transmitted to the remote control receiving unit 30 of the main control unit 3 through the key integrated control module, and then is converted by the signal receiver and the remote control signal receiving module of the remote control receiving unit 30 and sent to the processor of the main control unit 3. The main control unit 3 sends the indication signal to the feedback unit 41 of the automobile key 4. The feedback unit 41 includes a signal receiver, a key integrated control module, an LED control module and an LED indicator. After the indication signal from the main control unit 3 is received by the signal receiver and converted by the key integrated control module, the LED control module can control the lighting color and state of the LED indicator. Based on the above setting, in the embodiment, the first indication signal can adopt the state form of the green light of the LED indicator flickering, and the second indication signal can adopt the state form of the red light of the LED indicator flickering.

[0068] Specifically, as shown in Figure 6 、 Figure 7 、 Figure 8 , the main control unit 3 of the automobile monitors the signal transmission of the automobile key 4 in real time through the remote control receiving unit 30, that is, the automobile key signal detection program runs. When the pressure sensor on the automobile key 4 is pressed and operated, the signal is transmitted to the remote control receiving unit 30 through the key integrated control module, and then the main control unit 3 obtains the opening instruction signal of the door. At this moment, the temperature regulation unit 5 in the system is powered on, and whether the sealing strip 1 is frozen is judged by the temperature detected by the temperature sensor at the sealing strip 1, that is, the frozen state recognition and judgment module program is started. If it is not frozen, the main control unit 3 generates the first indication signal to the automobile key 4, and the LED indicator on the automobile key 4 flashes green light. If freezing occurs, the control program returns to the initial state to monitor the signal of the automobile key 4, and at the same time, the subsequent heating regulation step of the sealing strip 1 is carried out, that is, the sealing system water circulation integrated control module 50 is started to carry out the heating program.

[0069] For the specific steps of controlling the temperature regulation unit 5 to regulate the temperature of the sealing strip 1, of course, there are many specific setting schemes. In the embodiment, the heating regulation step includes:

[0070] The heating liquid is heated and driven to circulate in the circulation channel 100 until the temperature at the sealing strip 1 is raised to a set temperature range and maintained; whether the vehicle door is opened is detected, and when the vehicle door has been opened, the temperature regulation of the sealing strip 1 is ended.

[0071] There are of course various setting schemes for the specific temperature regulation mode of the temperature regulation unit 5 to the sealing strip 1. In the embodiment, the temperature regulation unit 5 includes a sealing system water circulation integrated control module 50, a signal acquisition device 51 connected to the sealing system water circulation integrated control module 50, a heating device 52 and a circulation pump control module 53, wherein the heating device 52 includes a heating control module and a heating assembly arranged in the liquid storage device; when the sealing system water circulation integrated control module 50 issues an instruction to start heating to the heating control module, the heating assembly starts to work to heat the heating liquid in the liquid storage device.

[0072] As shown in Figure 6 and shown in Figure 8 When the heating liquid is heated, the temperature of the heating liquid can be detected by the temperature sensor arranged in the liquid storage device, and when the heating liquid is heated to a set temperature, the heating can be stopped. The set temperature can be set between 40℃ and 60℃, for example, it is required to be heated to 50℃ or above. Based on the heating control of the heating liquid, a third indication signal can also be set in the control process, and when the heating liquid in the liquid storage device is heated but the temperature has not reached the required set temperature, the corresponding third indication signal can be indicated on the automobile key 4. The third indication signal can be in the form of yellow flashing LED light.

[0073] After the heating liquid is heated to the required temperature, the circulation pump assembly 2 can be started to supply the heating liquid to the circulation channel 100 of the sealing strip 1 for circulation to raise the temperature of the sealing strip 1. It should be pointed out that the heating liquid can use various liquids with good thermal conductivity, for example, water can be used. At this time, a temperature sensor can be arranged in the liquid storage device to timely monitor the temperature of the heating liquid in the liquid storage device; of course, it can also not be arranged. If the temperature sensor is not arranged in the liquid storage device, the temperature of the sealing strip 1 can be detected by the temperature sensor to stop the work of the heating assembly in time.

[0074] The sealing system water circulation integrated control module 50 controls the circulation pump assembly 2 to work through the circulation pump control module 53, pumps the heating liquid in the liquid storage device to the circulation channel 100 of the sealing strip 1 to form a circulation flow state, and can understand the heating condition of the heating liquid through the temperature sensor at the sealing strip 1. The signal of the temperature sensor at the sealing strip 1 is sent to the sealing system water circulation integrated control module 50 after conversion through the signal conversion module in the signal acquisition device 51, so that the system can understand the temperature condition at the sealing strip 1 in time. When the temperature at the sealing strip 1 is increased to the set temperature range, a certain time (which can be estimated and determined according to the test condition) is maintained, and after a reasonable time is maintained, the frozen ice at the sealing strip 1 is completely melted, so that the door can be smoothly opened; at this time, the first indication signal can be sent to the automobile key 4 to prompt the user that the condition for opening the door has been met.

[0075] In combination Figure 7 As shown, the control process related to the automobile key 4 is roughly as follows. After the control program of the system is initialized, when the automobile key 4 sends an opening instruction signal of the door, the main control unit 3 starts the frozen detection program, finds the frozen, and sends the second indication signal to the automobile key 4, and the LED indicator light of the automobile key 4 flashes red. At the same time, the main control unit 3 sends an instruction to the sealing system water circulation integrated control module 50 to start the temperature control process of the sealing strip 1, and when the frozen ice is melted by heating (judged based on the temperature condition at the sealing strip 1), the main control unit 3 sends the first indication signal to the automobile key 4, and the LED indicator light of the automobile key 4 flashes green; the user can know through the indication signal on the automobile key 4 that the door can be opened at this moment, and at this moment, the door is unlocked by operating the door opening button on the automobile key 4, and then the door can be pulled open.

[0076] In order to make the system accurately know the opening condition of the door, a detection switch for detecting whether the door is opened is preferably configured in the system. By setting a travel switch or other detection element at the hinge or other part of the door, the temperature control process of the sealing strip 1 is ended as a condition that the door has been opened, which can ensure that the ice at the sealing strip 1 is frozen again due to the stop of the heating temperature control of the sealing strip 1 during the waiting process after the frozen is eliminated but the door is not opened in time. Once the door is indeed opened, the entire temperature control of the sealing strip 1 is completely ended, which further ensures the reliability and effectiveness of the automobile sealing temperature control system.

[0077] In addition, after the temperature regulation of the sealing strip 1 is completed, the heating liquid in the circulating channel 100 should be exhausted, and the automobile sealing temperature control system should be powered off. After the temperature regulation of the sealing strip 1 is completely completed, the heating liquid in the circulating channel 100 is exhausted, which can eliminate the problem that the deformation performance and the sealing performance of the sealing strip 1 are affected due to the existence of the heating liquid in the sealing strip 1, and prevent the heating liquid in the circulating channel 100 from being frozen in the circulating channel 100 due to the stop of heating; thereby guaranteeing the use performance and the use durability of the sealing strip 1.

[0078] Based on the above overall setting, the computer program corresponding to the control method of the automobile sealing temperature control system of the embodiment can be compiled. The main control unit 3 is provided with a processor and a memory, and the memory stores the above computer program, which is loaded and executed by the processor to realize the control method of the application.

[0079] In specific implementation, the following specific schemes can be referred to for implementation.

[0080] Firstly, as shown in Figure 4 and combined with Figure 6 , in the technical scheme, the composition of the automobile sealing temperature control system mainly includes a main control unit 3, a remote control receiving unit 30, a man-machine interaction unit 31, an automobile key 4, a temperature regulation unit 5, and a sealing strip 1. Among them, the automobile key 4 includes an output unit 40 and a feedback unit 41, the temperature regulation unit 5 includes a sealing system water circulation integrated control module 50, a signal acquisition device 51, a heating device 52, a circulating pump control module 53, and a circulating pump assembly 2. The working state of the circulating pump assembly 2 is controlled by a program closed loop, the working state execution condition of the system is displayed by the LED indicator light on the automobile key 4, the system working condition and the related instructions are judged by the temperature sensor, the pressure sensor and other sensors in time, and the control input is provided to the main control unit 3, the main control unit 3 judges the system instructions and outputs the instructions to the related execution components of the temperature regulation unit 5, so as to complete the system closed loop control of "signal input-signal judgment-output instruction-execution command".

[0081] As shown in Figure 5As shown, four different working states of the system are provided in the technical solution: state 001 - power-off state, state 002 - water filling state (circulating pump assembly 2 runs at one gear), state 003 - hot water circulation state (circulating pump assembly 2 runs at two gears), and state 004 - emptying and draining state. The system is equipped with a switching mode of the four different states (the expansion of multiple gears in the water filling state and the hot water circulation state can be realized by setting the system program), and in actual work, the user selects the working mode by inputting the working instruction signal through the operation panel of the automobile key 4, and each system executes the working instruction; at the same time, the temperature sensor detects the temperature signal of the door heating, and when the temperature reaches the thawing temperature, it continues to run until the door is opened and the drainage is powered off.

[0082] When the system is in the power-off state, each sub-module of the control system is in the power-off mode, the system as a whole does not work, and the sensor is also powered off and stops working, only the signal receiving module of the automobile key 4 is in the working state so as to detect the signal emitted by the automobile key 4 at any time.

[0083] As shown, Figure 7 When the system is normally running, the instruction is input to the remote control receiving unit 30 through the operation panel of the automobile key 4, the main control unit 3 obtains the instruction signal and controls the temperature regulation unit 5 to operate; at the same time, the feedback unit 41 receives the feedback signal sent by the main control unit 3, inputs the RGB value displayed by the LED into the LED driving module, and the LED is lit and displayed as a green light at this time; at the same time, the temperature sensor transmits the detection temperature signal to the main control unit 3 for judgment. The main control unit 3 inputs the detection result into the PID controller, and after calculation, the PID controller returns the working instruction to the sealing system water circulation integrated control module 50. The circulating pump control module 53 transmits the electric signal to the circulating pump assembly 2 according to the input instruction, inputs the electric signal, controls the circulating pump assembly 2 to flush water into the circulating channel 100 of the sealing strip 1 or to pump water out of the circulating channel 100 (water in or water out), realizes the automatic control effect, and finally realizes the automobile door hot water circulation thawing control function. The whole process can be controlled and run by the program.

[0084] As shown, Figure 6 And Figure 8 When the automobile receives the start-up signal of the heat pump sent by the automobile key 4, the system starts to initialize and starts the freezing detection program at this time, and the signal acquisition device 51 sends the temperature signal to the sealing system water circulation integrated control module 50 for signal instruction judgment. The circulating pump control module 53 executes the control of the circulating pump control module 53 according to the judgment and the instruction input of the main control unit 3, and further controls the operation of the circulating pump assembly 2.

[0085] After the car key 4 sends a command signal, the working command is input to the main control unit 3 (the main control unit 3 can be integrated into the car's integrated control module). The running status judgment program compares the detected temperature (the temperature at the sealing strip 1 is ≥50℃). The heat pump control program runs the heating program and performs water filling and circulation. During the process, the temperature at the sealing strip is continuously judged until the temperature sensor sampling value reaches the set temperature range, for example, greater than or equal to the temperature set value (the temperature set value is 50℃).

[0086] After the temperature at the sealing strip 1 is maintained within the set temperature range for a certain period of time, it can be determined that the ice at the sealing strip 1 has melted, or the freezing condition can be confirmed by detecting whether the car door is actually opened. After the freezing condition is resolved, the temperature control of the sealing strip 1 is stopped, the heating fluid in the circulation channel 100 is drained, and the power to the car's sealing temperature control system is cut off. At this time, the entire control system is powered off, all subsystems cease operation, and only the key remote control signal receiving module continues to operate. When the command signal from the car key 4 is received again, the preset subsystem power supply program in the system is activated, power is supplied to the entire system, and the corresponding preset program is executed.

[0087] In summary, as follows: Figure 5 As shown, the automotive sealing temperature control system in this embodiment has four working states: state 001 (power off), state 002 (water filling), state 003 (heating water circulation), and state 004 (evacuation and drainage). Based on the different stages of the above control method, the automotive sealing temperature control system will switch between the above states to ultimately complete the temperature regulation and de-icing operation of the sealing strip 1.

[0088] In summary, the automotive sealing temperature control system and its control method of this invention adopt a water circulation charging and discharging method, avoiding the impact on the door sealing performance when not in use. Furthermore, taking into account the user's experience of driving in winter, it solves the problem of the car door being frozen and unable to be opened during use. Specifically, by setting different operating states of the circulation pump assembly 2, and in conjunction with the remote control operation of the car key 4, the system realizes functions such as start control, temperature control adjustment and thawing of the sealing strip 1, and emptying of the sealing strip 1 after freezing. Addressing the needs of cold winter environments and users, by preset operating states and preset sampling judgment values ​​(the operating state corresponds to the temperature sampling value), and in conjunction with the overall control of the main control unit 3, the sealing strip 1 can be adjusted to the heating temperature required by the user, improving compatibility with changes in ambient temperature.

[0089] It should be noted that the heating fluid in the automotive sealing temperature control system can be water, or it can be a non-flammable, thermally conductive, and non-freezing liquid such as antifreeze. For the circulation channel 100 of the sealing strip 1, a fluid inlet pipe can also be added to the circulation channel 100 for fluid drainage, etc.

[0090] In summary, the automobile sealing temperature control system and the control method thereof can realize the sealing function of the sealing strip 1 in the door sealing system, and can realize the temperature integrated control of the door sealing system by introducing the temperature control unit 5, cooperating with the algorithm module, and setting the PID algorithm as the temperature control and the closed-loop control algorithm as the control of the water flow port opening and closing, the temperature deviation range is set to ±0.3℃, and the closed-loop control time deviation range is set to ±0.2s. In addition, the output unit 40 of the opening button signal of the automobile key 4 and the remote control receiving unit 30 are added to automatically identify, detect and analyze and respond in real time, so that the user can control the opening and closing of the system, expand the temperature control and freezing ability of the door sealing system in the cold environment, realize the remote control and system control circulating operation heating and thawing function, and improve the user experience in the cold environment.
