[0030] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numbers in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible implementations consistent with one or more embodiments of the present application. Rather, they are merely examples of apparatuses and methods consistent with certain aspects of one or more embodiments of the present application, as detailed in the appended claims.

[0031] It should be noted that in other embodiments, the steps of the corresponding method are not necessarily performed in the order shown and described in this specification. In some other embodiments, the method may include more or fewer steps than those described in this specification. In addition, a single step described in this specification may be broken down into multiple steps for description in other embodiments, and multiple steps described in this specification may be combined into a single step for description in other embodiments.

[0032] At present, vehicle manufacturers or related institutions usually use the following methods to test the sealing of vehicles, including but not limited to: air leakage test, where inspectors can apply airflow to the sealing strip to observe whether there is air leakage from between the sealing strip and the vehicle body; water tightness test, where inspectors can flush the vehicle with high-pressure water flow or a water sprayer to observe whether the sealing strip can effectively prevent moisture from penetrating into the vehicle; sound test, where inspectors can use a sound source and measure the decibel level inside the vehicle with professional equipment to determine whether the sealing strip can effectively reduce the introduction of external noise.

[0033] The above methods can usually be used in combination to comprehensively evaluate the sealing performance of vehicle door sealing strips. However, these methods are difficult to provide quantitative visual data and are easily affected by the subjective judgment of the inspector. The accuracy of the inspection depends on the experience of the inspector. In addition, it is difficult to accurately locate the areas where the sealing performance of the sealing strip has problems.

[0034] In light of this, the present application provides a vehicle door seal testing method, device, electronic device, and medium. By scanning the three-dimensional data of the sealing strip and converting it into the coordinate system of the entire vehicle model, the interference data between the door / doorframe and the sealing strip at the cross-section corresponding to any desired location of the sealing strip when the door is closed can be predicted. Sealing testing can then be performed based on this interference data.

[0035] The present application provides a method for detecting the sealing of a vehicle door, comprising: performing a three-dimensional scan on a vehicle's body-in-white (BIW) to obtain three-dimensional model data, wherein the three-dimensional model data includes a door frame of the body-in-white, and three-dimensional model data corresponding to a sealing strip installed on one of the door frame and the door corresponding to the door frame, the other of the door frame and the door corresponding to the door frame serving as a detection reference portion for the sealing strip; using the three-dimensional model data corresponding to the door frame as a reference, converting the scanned three-dimensional model data into a whole vehicle model coordinate system corresponding to the vehicle; determining cross-sections corresponding to a plurality of positions to be detected of the sealing strip, and for each position to be detected among the plurality of positions to be detected, calculating interference data between the detection reference portion and the cross-section of the sealing strip corresponding to the position to be detected based on the position data of the detection reference portion in the whole vehicle model coordinate system when the door is in a closed state, and the position data corresponding to the sealing strip, and performing a sealing detection on the position to be detected based on the interference data.

[0036] It is understood that the sealing strip can be installed on either a door frame or a vehicle door. When the sealing strip is installed on a door frame, the corresponding vehicle door serves as the reference for detection of the sealing strip; when the sealing strip is installed on a vehicle door, the corresponding door frame serves as the reference for detection of the sealing strip. The following will first describe an embodiment in which the sealing strip is installed on a door frame, followed by an embodiment in which the sealing strip is installed on a vehicle door.

[0037] During implementation, for an embodiment in which a sealing strip is installed on a door frame, three-dimensional model data can be obtained by performing a three-dimensional scan of the vehicle's body-in-white; the three-dimensional model data includes three-dimensional model data corresponding to the door frame of the body-in-white and the sealing strip installed on the door frame.

[0038] For example, the vehicle's body-in-white can be scanned using a three-dimensional scanning device, and the three-dimensional model data obtained by the scan can include three-dimensional model data corresponding to the door frame of the body-in-white and the sealing strip installed on the door frame.

[0039] Then, the three-dimensional model data obtained by scanning can be converted into a whole vehicle model coordinate system corresponding to the vehicle based on the three-dimensional model data corresponding to the door frame.

[0040] For example, in order to match / align the scanned three-dimensional model data with the vehicle's whole vehicle model data, the scanned three-dimensional model data can be converted into the whole vehicle model coordinate system corresponding to the vehicle based on the three-dimensional model data corresponding to the door frame to obtain the three-dimensional model data in the whole vehicle model coordinate system.

[0041] Afterwards, the cross-section corresponding to the sealing strip at each position to be detected can be determined. According to the position data of the door corresponding to the door frame in the coordinate system of the whole vehicle model when the door is in a closed state, and the position data corresponding to the sealing strip, the interference data between the door and the sealing strip at the cross-section is calculated, and the sealing of the position to be detected is judged based on the interference data.

[0042] For example, because the sealing performance of a vehicle door is determined when it is closed, interference data is calculated based on the closed door position data within the vehicle model coordinate system, as well as the corresponding position data of the sealing strip. During this calculation, the cross-section of the sealing strip at any location to be tested can be determined. Based on the interference data between the door and the sealing strip at that cross-section, the sealing performance of that location can be determined.

[0043] As described above, by scanning the 3D data of the sealing strip and converting it into the coordinate system of the entire vehicle model, we can predict the interference data between the door and the sealing strip at the cross-section corresponding to any desired location on the sealing strip when the door is closed. This interference data can then be used to perform a seal test. This quantitative, visual data allows us to determine the sealing performance of the sealing strip, eliminating the influence of subjective factors. Furthermore, it allows us to precisely locate any sealing issues, allowing for more targeted adjustments.

[0044] The vehicle door sealing detection method of the present application is described in detail below with reference to the accompanying drawings.

[0045] Please refer to Figure 1, which is a flow chart of a vehicle door sealing detection method provided by an exemplary embodiment of the present application. As shown in Figure 1, the vehicle door sealing detection method includes the following steps 101 to 103.

[0046] In step 101 , a BIW of a vehicle is three-dimensionally scanned to obtain 3D model data; the 3D model data includes 3D model data corresponding to a door frame of the BIW and a sealing strip installed on the door frame.

[0047] In step 102 , the three-dimensional model data obtained by scanning is converted into a whole vehicle model coordinate system corresponding to the vehicle, based on the three-dimensional model data corresponding to the door frame.

[0048] In step 103, the cross-sections of the sealing strip corresponding to each position to be detected are determined, and based on the position data of the door corresponding to the door frame in the vehicle model coordinate system when the door is in a closed state, and the position data corresponding to the sealing strip, the interference data between the door and the sealing strip at the cross-sections are calculated, and the sealing performance of the position to be detected is detected based on the interference data.

[0049] In this embodiment, three-dimensional model data may be obtained by performing a three-dimensional scan on the vehicle's body-in-white.

[0050] For example, a common measurement device, such as a scanner or measuring instrument, can be used to perform a 3D scan of the vehicle's body-in-white (BIW), obtaining 3D model data corresponding to at least the door frame and the sealing strips installed on the door frame. This scanning process can be performed with the door closed or open.

[0051] In this embodiment, the three-dimensional model data corresponding to the door frame can be used as a reference to convert the scanned three-dimensional model data into a whole vehicle model coordinate system corresponding to the vehicle.

[0052] It is worth noting that the data obtained by scanning with a measuring device may be three-dimensional data in the measuring device coordinate system, which is not the vehicle model coordinate system. Therefore, it is necessary to unify the coordinate system and convert the three-dimensional data in the measuring device coordinate system into the vehicle model coordinate system.

[0053] For example, since the three-dimensional model data of the door frame already exists in the whole vehicle model coordinate system, the three-dimensional model data corresponding to the door frame can be used as a reference to convert the scanned three-dimensional model data into the whole vehicle model coordinate system corresponding to the vehicle.

[0054] Of course, those skilled in the art may also unify the coordinate system based on other parts of the vehicle or other positions.

[0055] In this embodiment, the cross-section corresponding to the sealing strip at each position to be detected can be determined. According to the position data of the door corresponding to the door frame in the coordinate system of the whole vehicle model when the door is in a closed state, and the position data corresponding to the sealing strip, the interference data between the door and the sealing strip at the cross-section is calculated, and the sealing judgment of the position to be detected is made based on the interference data.

[0056] As can be seen from the above, the sealing test of the vehicle door needs to be performed when the door is closed. However, since a three-dimensional model is used in this application, the sealing test needs to be performed based on the position data of the vehicle door corresponding to the door frame when the door is in the closed state in the vehicle model coordinate system corresponding to the vehicle, as well as the position data of the sealing strip.

[0057] For example, for any position to be detected, the cross-section of the sealing strip at the position to be detected can be determined first, and then the interference data between the door and the sealing strip at the cross-section when the door is in a closed state can be calculated. The sealing of the position to be detected can then be judged based on the interference data.

[0058] In an embodiment shown, a plurality of positions to be detected corresponding to the sealing strip may be determined according to pre-divided areas and a preset number.

[0059] Refer to FIG2 , which is a schematic diagram of a sealing strip installed on a door frame provided by an exemplary embodiment of the present application.

[0060] As shown in FIG2 , the sealing strip may be pre-divided into a plurality of regions, and the number of positions to be detected corresponding to each region may be set, so that the sealing performance of the positions to be detected in each region may be tested.

[0061] In an example, assuming that the number of preset positions to be inspected is 100, the 100 positions to be inspected on the sealing strip may be randomly selected, or the 100 positions to be inspected on the sealing strip may be selected as evenly as possible.

[0062] In one embodiment shown, the pre-divided areas include multiple areas, and the multiple areas are divided according to the degree of change in the curvature of the door frame's shape; the preset number is set based on the priority of the sealing detection corresponding to the multiple areas.

[0063] For example, the sealing strip can be divided into multiple areas based on the degree of curvature of the door frame. Taking Figure 2 as an example, for the front door frame of a vehicle, the sealing strip can be divided into a door sill area 201, a lower right rounded corner area 202, a B-pillar area 203, an upper right rounded corner area 204, a roof area 205, an upper left rounded corner area 206, an A-pillar area 207, and a lower left rounded corner area 208.

[0064] The starting point of the area division may be the left side of the threshold or the right side of the threshold, and this specification does not limit this.

[0065] Continuing with this example, the number of locations to be inspected in each area can be determined based on the sealing requirements of each region. Generally, the higher the sealing requirements for a region, the greater the number of locations to be inspected in that region, thereby ensuring the accuracy of the sealing test. For example, the number of locations to be inspected in the door sill area 201, the B-pillar area 203, the roof area 205, and the A-pillar area 207 is typically greater than the number of locations to be inspected in the fillet areas 202, 204, 206, and 208.

[0066] In one embodiment, the interference data includes at least three dimensions: the interference of the sealing strip in the door's screw-in direction caused by the door closing, the overlap area between the sealing strip and the door, and the interference of the sealing strip in the normal direction. Furthermore, the sealing performance of the location to be inspected can be determined based on the data in each dimension and the weights assigned to each dimension based on its corresponding priority.

[0067] For example, when calculating the interference data between a car door and a sealing strip at a cross-section, the above three dimensions can be calculated. These three dimensions are obtained by predicting the interference between the car door and the sealing strip when the car door is in the closed position.

[0068] It should be noted that the doors are connected to the body-in-white via hinges, and can rotate around the hinges to open and close. When the doors are closed, they interfere with the sealing strip on the door frame.

[0069] When the sealing strip interferes with the vehicle door, it will deform. This deformation can be used to ensure the sealing of the vehicle door. Therefore, the sealing of the position to be detected can be judged by predicting the deformation at the cross section of the position to be detected.

[0070] The interference fit of the sealing strip in the direction of door screwing refers to the distance from the contact point between the door and the sealing strip to the periphery of the sealing strip in the direction of door screwing; the overlapping area generated refers to the area of ​​the sealing strip that is squeezed and deformed due to the closing of the door; the interference fit of the sealing strip in the normal direction refers to the distance from the contact point between the door and the sealing strip to the periphery of the sealing strip in the normal direction.

[0071] Continuing with this example, we can prioritize the three dimensions above. For example, the order of priority might be: screw-in interference, overlap area, and normal interference. By assigning different weights to these three dimensions, we can then use the weights to score each dimension separately when assessing sealing performance, and determine the sealing performance based on the final score.

[0072] In one embodiment shown, an interference threshold can be set for each area of ​​the sealing strip, and the interference threshold corresponding to the position to be detected is determined based on the area to which the position to be detected belongs; and the interference data at the cross-section corresponding to the position to be detected is compared with the interference threshold corresponding to the position to be detected to judge the sealing of the position to be detected; wherein, the interference threshold is set based on the sealing priority of each area of ​​the sealing strip.

[0073] For example, different sealing priorities can be set for different areas of the sealing strip, and different interference thresholds can be set for areas with different sealing priorities. In this way, when making a sealing judgment, the area to which the position to be tested belongs can be determined first. Then, based on the interference threshold corresponding to the area, the interference threshold corresponding to the position to be tested can be determined. Then, based on the comparison of the interference data at the cross-section corresponding to the position to be tested with the interference threshold corresponding to the position to be tested, the sealing of the position to be tested can be judged.

[0074] In one embodiment shown, the interference data at the cross section corresponding to the position to be detected can also be visualized and output in the form of a chart; wherein the chart contains various areas of the sealing strip and the interference thresholds corresponding to each area; the interference thresholds include an upper limit value and a lower limit value.

[0075] For example, the interference data for the cross-sections corresponding to the locations to be inspected can be visualized in a graphical format, allowing inspectors to intuitively identify the tightness of different locations to be inspected. Furthermore, the graph can include the interference thresholds corresponding to each region, allowing inspectors to clearly identify which locations to be inspected have exceeded the interference threshold.

[0076] In addition, the above-mentioned interference threshold may include an upper limit value and a lower limit value, which can prevent the sealing strip from being too poorly sealed and the sealing strip from being too tight, making it difficult to open the door.

[0077] Taking Figures 4 to 6 as examples, Figure 4 is a schematic diagram of a visualization chart corresponding to the interference amount in the door screw-in direction provided by an exemplary embodiment of the present application, Figure 5 is a schematic diagram of a visualization chart corresponding to the overlapping area provided by an exemplary embodiment of the present application, and Figure 6 is a schematic diagram of a visualization chart corresponding to the interference amount in the normal direction provided by an exemplary embodiment of the present application.

[0078] As shown in Figures 4 through 6, the horizontal axis of the visualization chart can represent multiple pre-defined areas of the sealing strip, including the door sill, lower right corner, B-pillar, upper right corner, roof, upper left corner, A-pillar, and lower left corner. Furthermore, the visualization chart can display the interference thresholds corresponding to these different areas, with these thresholds varying depending on the sealing requirements of each area.

[0079] The interference threshold may be an upper limit value, a lower limit value, or both an upper limit value and a lower limit value.

[0080] Furthermore, the horizontal axis may also represent multiple locations to be detected in each different area.

[0081] Accordingly, the vertical axis of the visualization chart can represent the numerical value corresponding to the interference data. For each location to be inspected, the coordinate point of the location to be inspected on the chart can be determined based on the magnitude of the interference data of different dimensions calculated at the cross-section of the location to be inspected, and the coordinate points of multiple locations to be inspected can be connected.

[0082] For example, through the above visualization method, it can be intuitively understood from Figure 4 that the sealing of the top cover area exceeds the upper limit value, and the sealing strip is set too tightly in the top cover area, which will make the door difficult to open. The sealing of the A-pillar area varies too much, and the sealing basically does not meet the requirements. Therefore, the sealing of the A-pillar area is neither balanced nor meets the requirements. In Figure 5, although the interference data are all within the threshold range, the sealing of the B-pillar area fluctuates greatly. It can be determined whether the B-pillar area needs to be adjusted depending on the strictness of the sealing requirements. In Figure 6, there is not much change overall, which meets the sealing requirements of this dimension, that is, the interference amount in the normal direction.

[0083] In one embodiment shown, the body-in-white can be scanned three-dimensionally multiple times to obtain multiple sets of three-dimensional model data, multiple sets of interference data can be calculated based on the multiple sets of three-dimensional model data, the multiple sets of interference data can be fitted to obtain fitting results, and the sealing of the position to be inspected can be judged based on the fitting results.

[0084] Taking Figure 4 as an example, two 3D scans can be performed. Based on steps 102 and 103, first and second interference data can be calculated between the door and the sealing strip at the cross section, and visualized and output to obtain the two lines shown in Figure 4. Furthermore, these two lines can be fitted to obtain a smooth curve, and the sealing performance of each location to be inspected can be determined based on the fitted smooth curve.

[0085] In one embodiment, the sealing strip is adhesively mounted to the door frame by applying adhesive to one side of the strip and applying adhesive force to the other side using a roller. Furthermore, the adhesive force applied by the roller as it passes over different locations can be adjusted based on the sealing test results corresponding to the locations to be tested.

[0086] For example, the side of the sealing strip that contacts the door frame may be provided with adhesive for adhering to the door frame, while on the other side of the sealing strip, a roller may be used to apply external force to the sealing strip to make the sealing strip and the door frame adhere more tightly.

[0087] The adhesive force applied by the roller not only affects the adhesion between the sealing strip and the door frame, but also the degree of deformation of the sealing strip, thereby affecting the sealing performance. Therefore, based on the sealing performance assessment results, the adhesive force applied by the roller can be adjusted to ensure uniform and good sealing performance.

[0088] In this embodiment of the application, by scanning the three-dimensional data of the sealing strip and converting it into the coordinate system of the entire vehicle model, it is possible to predict the interference data between the door and the sealing strip at the cross section corresponding to any desired location on the sealing strip when the door is closed. This interference data can then be used to perform a seal test. This allows for quantitative, visual data to be used to determine the sealing strip's sealability, avoiding the influence of subjective factors. Furthermore, it allows for precise location of sealing strip problems, enabling more targeted adjustments to the seal's sealability.

[0089] The above implementation process is detailed in the implementation process of the corresponding steps in the above vehicle door sealing detection method. For relevant matters, please refer to the partial description of the method implementation method, which will not be repeated here.

[0090] An embodiment in which a sealing strip is installed on a vehicle door will be described in detail below.

[0091] During implementation, for an embodiment in which a sealing strip is installed on a vehicle door, three-dimensional model data can be obtained by performing a three-dimensional scan of the vehicle's body-in-white (BIW); the three-dimensional model data includes the door frame of the body-in-white and the three-dimensional model data corresponding to the sealing strip installed on the vehicle door corresponding to the door frame.

[0092] For example, the vehicle's body-in-white can be scanned using a three-dimensional scanning device, and the three-dimensional model data obtained by the scan may include three-dimensional model data corresponding to the door frame of the body-in-white and the sealing strip installed on the door.

[0093] Then, the three-dimensional model data obtained by scanning can be converted into a whole vehicle model coordinate system corresponding to the vehicle based on the three-dimensional model data corresponding to the door frame.

[0094] For example, in order to match / align the scanned three-dimensional model data with the vehicle's whole vehicle model data, the scanned three-dimensional model data can be converted into the whole vehicle model coordinate system corresponding to the vehicle based on the three-dimensional model data corresponding to the door frame to obtain the three-dimensional model data in the whole vehicle model coordinate system.

[0095] Afterwards, the cross-section corresponding to the sealing strip at each position to be detected can be determined. According to the position data corresponding to the door frame when the door is in a closed state in the coordinate system of the whole vehicle model, and the position data corresponding to the sealing strip, the interference data between the door frame and the sealing strip at the cross-section is calculated, and the sealing performance of the position to be detected is detected based on the interference data.

[0096] For example, because the sealing performance of a vehicle door is determined when the door is closed, interference data is calculated based on the position data of the door frame and the sealing strip when the door is closed in the vehicle model coordinate system. During this calculation, the cross-section of the sealing strip at any location to be tested can be determined. Based on the interference data between the door frame and the sealing strip at that cross-section, the sealing performance of that location can be determined.

[0097] As described above, by scanning the 3D data of the sealing strip and converting it into the coordinate system of the vehicle model, we can predict the interference data between the door frame and the sealing strip at the cross-section corresponding to any desired location on the sealing strip when the door is closed. This interference data can then be used to perform a seal test. This quantitative, visual data allows us to determine the sealing strip's tightness, avoiding the influence of subjective factors. Furthermore, it allows us to precisely locate any sealing issues, allowing for more targeted adjustments.

[0098] When the sealing strip is installed on the vehicle door, the vehicle door sealing detection method includes the following steps:

[0099] 3D model data is obtained by performing a 3D scan on the vehicle's body-in-white (BIW); the 3D model data includes 3D model data corresponding to the door frame of the BIW and the sealing strip installed on the door;

[0100] Based on the three-dimensional model data corresponding to the door frame, the scanned three-dimensional model data is converted into the whole vehicle model coordinate system corresponding to the vehicle;

[0101] Determine the cross-section of the sealing strip at each position to be tested, calculate the interference data of the door frame and the sealing strip at the cross-section based on the position data of the door frame when the door is in a closed state in the vehicle model coordinate system, and perform a sealing test on the position to be tested based on the interference data.

[0102] In this embodiment, three-dimensional model data may be obtained by performing a three-dimensional scan on the vehicle's body-in-white.

[0103] For example, a common measurement device, such as a scanner or measuring instrument, can be used to perform a 3D scan of the vehicle's body-in-white (BIW), obtaining 3D model data for at least the door frames and the door seals. This scanning process can be performed with the doors closed or open.

[0104] In this embodiment, the three-dimensional model data corresponding to the door frame can be used as a reference to convert the scanned three-dimensional model data into a whole vehicle model coordinate system corresponding to the vehicle.

[0105] It is worth noting that the data obtained by scanning with a measuring device may be three-dimensional data in the measuring device coordinate system, which is not the vehicle model coordinate system. Therefore, it is necessary to unify the coordinate system and convert the three-dimensional data in the measuring device coordinate system into the vehicle model coordinate system.

[0106] For example, since the three-dimensional model data of the door frame already exists in the whole vehicle model coordinate system, the three-dimensional model data corresponding to the door frame can be used as a reference to convert the scanned three-dimensional model data into the whole vehicle model coordinate system corresponding to the vehicle.

[0107] Of course, those skilled in the art may also unify the coordinate system based on other parts of the vehicle or other positions.

[0108] In this embodiment, the cross-section corresponding to the sealing strip at each position to be detected can be determined. According to the position data corresponding to the door frame when the door is in a closed state in the coordinate system of the whole vehicle model, and the position data corresponding to the sealing strip, the interference data between the door frame and the sealing strip at the cross-section is calculated, and the sealing judgment of the position to be detected is made based on the interference data.

[0109] As can be seen from the above, the sealing test of the vehicle door needs to be performed when the door is closed. However, since a three-dimensional model is used in this application, the sealing test needs to be performed based on the position data corresponding to the door frame and the position data corresponding to the sealing strip when the door is in the closed state in the vehicle model coordinate system corresponding to the vehicle.

[0110] For example, for any position to be detected, the cross-section of the sealing strip at the position to be detected can be determined first, and then the interference data of the door frame and the sealing strip at the cross-section when the car door is in a closed state can be calculated. The sealing of the position to be detected can then be judged based on the interference data.

[0111] In an embodiment shown, a plurality of positions to be detected corresponding to the sealing strip may be determined according to pre-divided areas and a preset number.

[0112] FIG2 can also be viewed as a schematic diagram of the door sealing strip corresponding to the door frame when the door is in a closed state.

[0113] As shown in FIG2 , the sealing strip can be pre-divided into multiple areas based on the door frame, and the number of positions to be detected corresponding to each area can be set, so that the sealing performance of the positions to be detected in each area can be tested.

[0114] In an example, assuming that the number of preset positions to be inspected is 100, the 100 positions to be inspected on the sealing strip may be randomly selected, or the 100 positions to be inspected on the sealing strip may be selected as evenly as possible.

[0115] In one embodiment shown, the pre-divided areas include multiple areas, and the multiple areas are divided according to the degree of change in the curvature of the door frame's shape; the preset number is set based on the priority of the sealing detection corresponding to the multiple areas.

[0116] For example, the sealing strip can be divided into multiple areas based on the degree of curvature of the door frame. Taking Figure 2 as an example, for the front door frame of a vehicle, the sealing strip can be divided into a door sill area 201, a lower right rounded corner area 202, a B-pillar area 203, an upper right rounded corner area 204, a roof area 205, an upper left rounded corner area 206, an A-pillar area 207, and a lower left rounded corner area 208.

[0117] The starting point of the area division may be the left side of the threshold or the right side of the threshold, and this specification does not limit this.

[0118] Continuing with this example, the number of locations to be inspected in each area can be determined based on the sealing requirements of each region. Generally, the higher the sealing requirements for a region, the greater the number of locations to be inspected in that region, thereby ensuring the accuracy of the sealing test. For example, the number of locations to be inspected in the door sill area 201, the B-pillar area 203, the roof area 205, and the A-pillar area 207 is typically greater than the number of locations to be inspected in the fillet areas 202, 204, 206, and 208.

[0119] In one embodiment, the interference data includes at least three dimensions: the interference of the sealing strip in the door's screw-in direction caused by the door closing, the overlap area between the sealing strip and the door frame, and the interference of the sealing strip in the normal direction. Furthermore, the sealing performance of the location to be inspected can be determined based on the data in each dimension and the weights assigned to each dimension based on its corresponding priority.

[0120] For example, when calculating the interference data between a door frame and a sealing strip at a cross-section, the above three dimensions can be calculated. These three dimensions are obtained by predicting the interference between the door frame and the sealing strip when the door is in the closed position.

[0121] Refer to FIG3 , which is a schematic diagram showing interference between a sealing strip and a door frame at a cross section provided by an exemplary embodiment of the present application.

[0122] It should be noted that the door is connected to the body-in-white via a hinge, and the door can rotate around the hinge to open and close. When the door is closed, the sealing strip on the door will interfere with the door frame.

[0123] Taking Figure 3 as an example, the sealing strip 301 in Figure 3 will be deformed when interfering with the door frame 302. This deformation can be used to ensure the sealing of the car door 303. Therefore, the sealing of the position to be detected can be judged by predicting the deformation at the cross-section of the position to be detected.

[0124] As shown in Figure 3, the interference fit of the sealing strip in the door screw-in direction refers to the distance from the contact point between the door frame and the sealing strip to the periphery of the sealing strip in the door screw-in direction; the resulting overlapping area refers to the area of ​​the sealing strip that is squeezed and deformed due to the closing of the door; the interference fit of the sealing strip in the normal direction refers to the distance from the contact point between the door frame and the sealing strip to the periphery of the sealing strip in the normal direction.

[0125] Continuing with this example, we can prioritize the three dimensions above. For example, the order of priority might be: screw-in interference, overlap area, and normal interference. By assigning different weights to these three dimensions, we can then use the weights to score each dimension separately when assessing sealing performance, and determine the sealing performance based on the final score.

[0126] In one embodiment shown, an interference threshold can be set for each area of ​​the sealing strip, and the interference threshold corresponding to the position to be detected is determined based on the area to which the position to be detected belongs; and the interference data at the cross-section corresponding to the position to be detected is compared with the interference threshold corresponding to the position to be detected to judge the sealing of the position to be detected; wherein, the interference threshold is set based on the sealing priority of each area of ​​the sealing strip.

[0127] For example, different sealing priorities can be set for different areas of the sealing strip, and different interference thresholds can be set for areas with different sealing priorities. In this way, when making a sealing judgment, the area to which the position to be tested belongs can be determined first. Then, based on the interference threshold corresponding to the area, the interference threshold corresponding to the position to be tested can be determined. Then, based on the comparison of the interference data at the cross-section corresponding to the position to be tested with the interference threshold corresponding to the position to be tested, the sealing of the position to be tested can be judged.

[0128] In one embodiment shown, the interference data at the cross section corresponding to the position to be detected can also be visualized and output in the form of a chart; wherein the chart contains various areas of the sealing strip and the interference thresholds corresponding to each area; the interference thresholds include an upper limit value and a lower limit value.

[0129] For example, the interference data for the cross-sections corresponding to the locations to be inspected can be visualized in a graphical format, allowing inspectors to intuitively identify the tightness of different locations to be inspected. Furthermore, the graph can include the interference thresholds corresponding to each region, allowing inspectors to clearly identify which locations to be inspected have exceeded the interference threshold.

[0130] In addition, the above-mentioned interference threshold may include an upper limit value and a lower limit value, which can prevent the sealing strip from being too poorly sealed and the sealing strip from being too tight, making it difficult to open the door.

[0131] For an example of visually outputting interference data in the form of a chart, reference may be made to the above description in conjunction with FIG. 4 to FIG. 6 , which will not be repeated here.

[0132] In one embodiment shown, the body-in-white can be scanned three-dimensionally multiple times to obtain multiple sets of three-dimensional model data, multiple sets of interference data can be calculated based on the multiple sets of three-dimensional model data, the multiple sets of interference data can be fitted to obtain fitting results, and the sealing of the position to be inspected can be judged based on the fitting results.

[0133] In one embodiment, the sealing strip is adhesively installed on the vehicle door by applying adhesive to one side of the strip and applying adhesive force to the other side using a roller. Furthermore, the adhesive force applied by the roller as it passes over different locations to be tested can be adjusted based on the sealing test results corresponding to the locations to be tested.

[0134] For example, as shown in FIG3 , the side of the sealing strip 301 that contacts the vehicle door 303 may be provided with adhesive 304 for adhering to the vehicle door 303. On the other side of the sealing strip 301, a roller may be used to apply external force to the sealing strip 301 to make the sealing strip 301 and the vehicle door 303 adhere more tightly.

[0135] The adhesive force applied by the roller not only affects the adhesion between the sealing strip and the door, but also the degree of deformation of the sealing strip, thus affecting the sealing performance. Therefore, based on the sealing performance assessment results, the adhesive force applied by the roller can be adjusted to ensure uniform and good sealing performance.

[0136] In this embodiment of the present application, by scanning the three-dimensional data of the sealing strip and converting it into the coordinate system of the entire vehicle model, it is possible to predict the interference data between the door frame and the sealing strip at the cross-section corresponding to any desired location of the sealing strip when the door is closed. This interference data can then be used to perform a seal test. This allows for quantitative, visual data to be used to determine the sealing strip's sealability, avoiding the influence of subjective factors. Furthermore, it allows for precise location of sealing strip problems, enabling more targeted adjustments to the seal's sealability.
