[0067] The following describes the preferred embodiments of the present application with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present application, and are not used to limit the present application.

[0068] Figure 1 Flowchart of a sealing structure control method in an embodiment of the present application. As Figure 1 shown, the method can be implemented as the following steps S101 - S103:

[0069] In step S101, the body control module monitors the door switch status signal in real time;

[0070] In step S102, when a door closed signal is detected, power is supplied to the sealing structure. The sealing structure includes a sealing strip, and the sealing strip contains a magnetic material. When the sealing structure is powered on, the magnetic material activates the magnetic adsorption function under the action of the current;

[0071] In step S103, when a door open signal is detected, the current supply to the magnetic material of the sealing strip is cut off.

[0072] Figure 2 Cross-sectional view of the sealing structure in an embodiment of the present application. As Figure 2 shown, the sealing structure includes a sealing strip 201, and the sealing strip contains a magnetic sponge rubber bubble tube 202 mixed with a magnetic material. The sealing strip is formed by co-extrusion with an equal cross-section. The material of the bubble tube is not the common EPDM sponge rubber, but a magnetic sponge rubber uniformly mixed with a magnetic material. When the magnetic sponge rubber is not powered on, it is no different from ordinary sponge rubber. However, once powered on, the magnetic material will instantly activate the magnetic function, enabling the sealing strip to tightly adsorb on the surface of the metal steel door, forming a strong magnetic adsorption force that is almost impossible to easily pull apart. Only after power-off, the magnetic sponge rubber will lose the magnetic adsorption force, and the door can be easily opened.

[0073] In addition, the sealing strip is connected to the body control module of the whole vehicle through a wire harness. Figure 3 It is a schematic diagram of the wire harness connection structure at the corner of the sealing structure in an embodiment of the present application. As Figure 3 shown, the sealing structure may further include a wire harness plug 301 and a wire 302 for connecting the wire harness of the whole vehicle and the body control module; the wire connects the sealing strip to the wire harness plug, thereby enabling the sealing strip to communicate with the body control module of the whole vehicle. In addition, it may further include a sealing strip corner structure 303 for connecting the wire to the magnetic material. Figure 4 It is an example diagram of the application of the sealing structure in an embodiment of the present application. As Figure 4 shown, the sealing strip is generally installed on the door frame on the side of the vehicle body, and the magnetic sponge bubble tube of the sealing strip contacts the door to achieve the sealing performance. In addition, in the sealing structure provided in the present application, a magnetic material is innovatively introduced on the basis of the conventional door frame strip, and a current-carrying wire harness and connectors are added. Structurally, the original sealing structure of the door frame sealing strip is ensured, and there will be no conflict with the layout structure of the original parts. Therefore, by adding the application of the magnetic sealing material in the sealing strip, the suction force between the bubble tube of the sealing strip and the vehicle door sheet metal is improved, thereby improving the overall sealing performance of the whole vehicle. And by connecting the wire harness to the body control module of the whole vehicle, the body control module identifies the door opening and closing commands and then powers on and off the sealing strip to realize the magnetic suction function of the sealing strip. This kind of sealing strip structure is extremely compact, has no influence on the layout of the whole vehicle, and is convenient for assembly.

[0074] Specifically, the body control module monitors the door opening and closing status in real time. Through the real-time monitoring function of the door opening and closing status, once the body control module detects a door closing or opening signal, it sends a command to power on or cut off the current to the sealing structure.

[0075] When a door closing signal is detected, power is supplied to the sealing structure. Among them, the sealing structure includes a sealing strip, and the sealing strip contains a magnetic material. When the sealing structure is powered on, the magnetic material activates the magnetic adsorption function under the action of the current, and seals through the close magnetic adsorption with the corresponding metal parts on the door, which can not only effectively prevent external noise, dust, rain, etc. from entering the vehicle, but also improve the overall sound insulation performance and riding comfort of the vehicle.

[0076] Since when the vehicle is in a high-speed driving state, the requirement for the sealing performance is more stringent. Therefore, in one embodiment, the current vehicle speed data can also be obtained through a vehicle speed sensor; when the vehicle speed exceeds a preset threshold, the current intensity of the sealing strip is increased to improve the sealing force to ensure that the vehicle can still maintain a good sealing effect during high-speed driving.

[0077] During the power-on activation process, in order to achieve fine adjustment of the magnetic force, the current intensity can also be controlled by pulse width modulation (PWM) during the power-on activation process to achieve hierarchical adjustment of the magnetic force. The PWM technology can accurately control the average value of the output current by adjusting the duty cycle of the pulse signal. The body control module can dynamically adjust the duty cycle of the PWM signal according to different operating conditions, such as vehicle speed, external environmental conditions, etc., so as to achieve hierarchical adjustment of the magnetic force. This hierarchical adjustment method can not only meet the sealing requirements under different driving states, but also effectively reduce energy consumption and improve the overall efficiency of the system.

[0078] In addition, considering the influence of environmental temperature on the performance of magnetic materials, in an embodiment of the present application, the compensation coefficient of the energizing current is automatically adjusted according to the detected environmental temperature parameter. When the environmental temperature changes, the magnetic properties of the magnetic material will also change accordingly. By adjusting the current compensation coefficient, it can be ensured that the sealing strip can maintain stable magnetic adsorption force and sealing performance in different temperature environments, thus improving the adaptability and reliability of the system.

[0079] The power-on activation of the magnetic material adopts a stepped current control method, and the current intensity is automatically adjusted according to the door closing force. During the power-on activation process of the magnetic material, in order to achieve more intelligent control, the system adopts a stepped current control method. This control method can automatically adjust the current intensity according to the door closing force. When the door is closed, the pressure sensor installed on the door or the vehicle body will detect the door closing force in real time and convert the corresponding pressure signal into an electrical signal and transmit it to the body control module. The body control module adjusts the current intensity output to the sealing strip step by step according to the received pressure signal according to the preset stepped current control strategy. If the door closing force is large, it means that a stronger sealing force is required, and the body control module will increase the current intensity accordingly; on the contrary, if the door closing force is small, the current intensity will also be appropriately reduced. This method of automatically adjusting the current intensity according to the door closing force can not only ensure that the door can obtain an appropriate sealing force when it is closed, but also avoid energy waste and excessive wear of the sealing strip caused by excessive current.

[0080] When the door opening signal is detected, the current supply to the magnetic material of the sealing strip is cut off. At this time, the magnetic adsorption function of the magnetic material disappears, the magnetic adsorption force between the sealing strip and the door is released, and the door can be easily opened. This fast-response current cut-off mechanism ensures the smoothness and convenience of the door opening operation.

[0081] In addition, when abnormal current or short circuit is detected, the power supply of the sealing strip is automatically cut off. During the operation of the system, to ensure the safety of the vehicle and passengers, the system also has a perfect fault detection and protection function. When abnormal current or short circuit is detected, the body control module will quickly and automatically cut off the power supply of the sealing strip, preventing potential safety hazards such as electrical faults and fires caused by abnormal current. This active protection mechanism can effectively improve the safety and reliability of the system and ensure the normal operation of the vehicle.

[0082] Automatically enter the low-power mode when the vehicle is turned off, only maintaining the basic detection current. When the vehicle is turned off, to reduce energy consumption and extend the service life of the vehicle battery, the system will automatically enter the low-power mode. In the low-power mode, the system only maintains the basic detection current for continuously monitoring key parameters such as the door opening and closing status. Once a change in the door status or other events that require the system to respond are detected, the system will immediately wake up from the low-power mode and resume normal operation. This intelligent power consumption management mode not only meets the vehicle's need for real-time monitoring but also effectively reduces energy consumption, reflecting the efficiency and energy-saving nature of the system.

[0083] The beneficial effects of this application are as follows: The body control module monitors the door opening and closing status signals in real time; when a door closing signal is detected, power is supplied to the sealing structure, where the sealing structure includes a sealing strip containing magnetic material. When the sealing structure is powered on, the magnetic material activates the magnetic adsorption function under the action of the current, thereby improving the sealing performance of the door when it is closed; when a door opening signal is detected, the current supply to the magnetic material of the sealing strip is cut off, and the closing force will not increase. Therefore, this method improves the sealing performance while avoiding excessive closing force.

[0084] In one embodiment, the above method can also be implemented as the following steps A1 - A2:

[0085] In step A1, the current vehicle speed data is obtained through the vehicle speed sensor;

[0086] In step A2, when the vehicle speed exceeds the preset threshold, the current intensity of the sealing strip is increased to improve the sealing force.

[0087] In one embodiment, the above method can also be implemented as the following steps:

[0088] The power-on activation process uses pulse width modulation (PWM) to control the current intensity to achieve hierarchical adjustment of the magnetic force.
