[0059] like Figure 1 The figure shows a working flow chart of a method for determining a deviation of an outer door handle according to an embodiment of the present invention, wherein the outer door handle is installed on a door inner panel reinforcement, and a molding surface of the outer door handle is placed on an outer door panel outer handle installation hole of a door outer panel, comprising:

[0060] Step S101, based on the scan data of the door inner panel reinforcement, the door outer panel and the outer handle, construct a mounting plane passing through the mounting point on the door inner panel reinforcement, construct a through hole straight line extending along the outer handle mounting hole of the door outer panel, and construct a molding surface line segment consistent with the outer handle molding surface of the outer handle;

[0061] Step S102, calculating the difference between the through hole straight line and the front end of the modeling surface line segment along the vertical modeling surface as the first face difference, and calculating the difference between the through hole straight line and the rear end of the modeling surface line segment along the vertical modeling surface as the second face difference;

[0062] Step S103, determining the corresponding change relationship between the front end of the modeling surface segment, the rear end of the modeling surface segment and the installation point on the installation plane along the vertical modeling surface distance through the spatial position relationship between the installation plane and the modeling surface segment;

[0063] Step S104, calculating the gasket thickness that needs to be adjusted for each of the mounting points based on the first flush, the second flush, and the corresponding change relationship.

[0064] Specifically, the present invention can be applied to electronic devices with processing capabilities, such as computers.

[0065] like Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the outer door handle 1 is mounted on the inner door panel reinforcement 2, and the inner door panel reinforcement 2 can be fixed on the inner door panel 4. The styling surface 11 of the outer door handle 1 is placed in the outer door panel surface outer handle mounting hole 31 of the outer door panel surface 3. According to the styling requirements, the surface difference between the styling surface 11 and the outer surface of the outer door panel surface 3 is 0±1.0 mm. Each mounting point is bolted to the outer door handle 1 and the inner door panel reinforcement 2 by bolts and nuts 5. A gasket 6 is sleeved on the bolt 5. In order to meet the styling requirements, the thickness of the gasket 6 at the mounting point needs to be adjusted.

[0066] After acquiring the scanning data of the door inner panel reinforcement, the door outer panel and the outer handle, execute step S101, based on the scanning data of the door inner panel reinforcement, the door outer panel and the outer handle, construct an installation plane passing through the installation point on the door inner panel reinforcement, construct a through-hole straight line extending along the outer handle mounting hole of the door outer panel, and construct a styling surface line segment consistent with the outer handle styling surface of the outer handle.

[0067] In some embodiments, the method of constructing a mounting plane passing through a mounting point on the inner door panel reinforcement, a through hole straight line extending along the outer handle mounting hole on the outer door panel, and a molding surface line segment consistent with the outer handle molding surface of the outer handle based on the scanned data of the inner door panel reinforcement, the outer door panel, and the outer handle includes:

[0068] Constructing a scanning coordinate system of the inner panel reinforcement according to the scanning data of the inner panel reinforcement, constructing a scanning coordinate system of the outer panel surface according to the scanning data of the outer panel surface, and constructing a scanning coordinate system of the outer handle molding surface according to the scanning data of the outer handle molding surface;

[0069] Obtain the digital model coordinate system of the inner panel reinforcement, the digital model coordinate system of the outer panel surface, and the digital model coordinate system of the outer handle molding surface;

[0070] Align the scanning coordinate system of the inner panel reinforcement with the digital model coordinate system of the inner panel reinforcement, align the scanning coordinate system of the outer panel surface with the digital model coordinate system of the outer panel surface, and align the scanning coordinate system of the outer handle modeling surface with the digital model coordinate system of the outer handle modeling surface;

[0071] Put the scanning coordinate system of the inner panel reinforcement, the scanning coordinate system of the outer panel surface, and the scanning coordinate system of the outer handle molding surface into the same three-dimensional coordinate system, and convert the coordinates of the three scanning coordinate systems into the coordinates in the same three-dimensional coordinate system;

[0072] In the same three-dimensional coordinate system, a mounting plane passing through the mounting point on the inner door panel reinforcement is constructed, a through-hole straight line extending along the outer handle mounting hole of the outer door panel is constructed, and a styling surface line segment consistent with the outer handle styling surface of the outer handle is constructed.

[0073] Specifically, first construct the scanning coordinate system, including:

[0074] Select three points of the inner panel reinforcement (not limited to installation points and feature points) to construct a scanning coordinate system of the inner panel reinforcement (coordinates are X1, Y1, Z1);

[0075] Select 3 points on the outer panel (not limited to installation points and feature points) to construct a scanning coordinate system of the outer panel (coordinates are X2, Y2, Z2)

[0076] Select three points of the outer handle modeling surface (not limited to installation points and feature points) to construct a coordinate system of the outer handle modeling surface (coordinates are X3, Y3, Z3).

[0077] From the 3D digital model, select three points of the inner panel reinforcement (not limited to installation points and feature points), and determine the coordinates of the three points in the 3D digital model coordinate system;

[0078] From the 3D digital model, select three points on the outer panel surface (not limited to installation points and feature points), and determine the coordinates of the three points in the 3D digital model coordinate system;

[0079] From the 3D digital model, select three points (not limited to installation points and feature points) of the outer handle modeling surface (located in the outer handle mounting hole), and determine the coordinates of the three points in the 3D digital model coordinate system.

[0080] Note: When constructing the scanning surface coordinate system and the theoretical 3D digital model coordinate system of the same part, the selected points must be consistent.

[0081] Then, the scanned parts are assembled through the coordinate system. Specifically, according to the principle of aligning the scanned surface of the same part with the coordinate system of the theoretical 3D digital model, the same points in the scanned coordinate system of the three parts are aligned with the same points of the same part in the 3D digital model coordinate system and assembled together. Thus, the three scanned coordinate systems are unified into an overall three-dimensional coordinate system.

[0082] Finally, construct a plane passing through multiple installation points of the inner panel reinforcement, defined as: installation plane. Construct a straight line along the X direction / left and right direction of the outer handle installation hole on the outer panel, defined as: through-hole straight line. Select a straight line along the X direction / left and right direction of the outer handle molding surface, and cut out a molding surface line segment consistent with the outer handle molding surface from the straight line. Among them, the front end of the molding surface line segment coincides with the front end of the outer handle molding surface, and the rear end of the molding surface line segment coincides with the rear end of the outer handle molding surface.

[0083] Then, step S102 is executed to calculate the difference between the through hole straight line and the front end of the modeling surface segment along the vertical modeling surface as the first face difference, and calculate the difference between the through hole straight line and the rear end of the modeling surface segment along the vertical modeling surface as the second face difference.

[0084] like Figure 7 As shown, there is a difference between the outer panel surface 3 and the front end 111 of the modeling surface 11 along the vertical modeling surface, and there is a difference between the outer panel surface 3 and the front end 112 of the modeling surface 11 along the vertical modeling surface.

[0085] The outer plate surface 11 is equivalent to a through hole straight line, and the modeling surface 11 is equivalent to a modeling surface line segment. Among them, the front end 111 of the modeling surface 11 is the front end of the modeling surface line segment, and the rear end 112 of the modeling surface 11 is the rear end of the modeling surface line segment.

[0086] The difference between the through hole straight line and the front end of the modeling surface line segment on the vertical modeling surface is used as the first face difference, and the difference between the through hole straight line and the rear end of the modeling surface line segment on the vertical modeling surface is used as the second face difference.

[0087] Then, step S103 is executed to determine the corresponding change relationship between the front end of the modeling surface segment, the rear end of the modeling surface segment and the installation point on the installation plane along the vertical modeling surface distance through the spatial position relationship between the installation plane and the modeling surface segment.

[0088] Specifically, through the spatial position relationship between the installation product name and the modeling surface line segment, the relationship between the normal distances between the front and rear end points of the modeling surface line segment and multiple points on the installation plane can be calculated by mathematical methods.

[0089] Finally, step S104 is performed to calculate the gasket thickness that needs to be adjusted for each of the mounting points based on the first flush, the second flush, and the corresponding change relationship.

[0090] Specifically, after the thickness of the gasket is determined, the operation instruction screen displays that a plurality of installation points each need to add gaskets of different thicknesses.

[0091] The present invention constructs an installation plane passing through the installation point on the door inner panel reinforcement, constructs a through-hole straight line extending along the outer handle installation hole of the door outer panel, and constructs a styling surface line segment consistent with the outer handle styling surface of the outer handle. The thickness of the gasket that needs to be adjusted at each installation point is determined through the spatial position relationship between the installation surface and the styling surface line segment, so that the operator can directly adjust the gasket thickness according to the prompt when installing the outer handle and complete the operation quickly.

[0092] like Figure 2 The figure shows a working flow chart of a method for determining a deviation of an outer door handle in another embodiment of the present invention, wherein the outer door handle is installed on a door inner panel reinforcement, and a shaped surface of the outer door handle is placed on an outer door panel outer handle installation hole of a door outer panel. The method comprises:

[0093] Step S201, based on the scan data of the door inner panel reinforcement, the door outer panel and the outer handle, construct an installation plane passing through the installation point on the door inner panel reinforcement, construct a through-hole straight line extending along the outer handle installation hole of the door outer panel, and construct a styling surface line segment consistent with the outer handle styling surface of the outer handle, the installation point includes a first installation point, a second installation point and a third installation point, the projection point of the first installation point projected on the extension line of the styling surface line segment is located outside the styling surface line segment, the projection line passing through the second installation point and the third installation point intersects with the styling surface line segment, and the intersection point is on the styling surface line segment.

[0094] Step S202, calculating the difference between the through hole straight line and the front end of the modeling surface line segment along the vertical modeling surface as the first face difference, and calculating the difference between the through hole straight line and the rear end of the modeling surface line segment along the vertical modeling surface as the second face difference.

[0095] Step S203, determining the corresponding change relationship between the front end of the modeling surface segment, the rear end of the modeling surface segment and the distance of the projection point along the vertical modeling surface through the spatial position relationship between the installation plane and the modeling surface segment;

[0096] The corresponding change relationship between the front end of the modeling surface line segment, the rear end of the modeling surface line segment and the projection point along the vertical modeling surface distance is used as the corresponding change relationship between the front end of the modeling surface line segment, the rear end of the modeling surface line segment and the first installation point on the installation plane along the vertical modeling surface distance.

[0097] Step S204, calculating a first mounting point initial adjustment amount of the first mounting point, a second mounting point adjustment amount of the second mounting point, and a third mounting point adjustment amount of the third mounting point according to the first flush and the second flush.

[0098] In one embodiment, the calculating, according to the first flush and the second flush, a first mounting point initial adjustment amount of the first mounting point, a second mounting point adjustment amount of the second mounting point, and a third mounting point adjustment amount of the third mounting point includes:

[0099] The first mounting point initial adjustment amount of the first mounting point, the second mounting point adjustment amount of the second mounting point, and the third mounting point adjustment amount of the third mounting point are calculated as (D1+E1) / 2, where D1 is the first face difference and E1 is the second face difference.

[0100] Step S205, calculating a first initial adjustment amount of the first flush and a second initial adjustment amount of the second flush according to the first installation point initial adjustment amount, the second installation point adjustment amount, and the third installation point adjustment amount.

[0101] Step S206: Based on the corresponding relationship, determine the first mounting point re-adjustment amount according to the first flush initial adjustment amount and the second flush initial adjustment amount.

[0102] In one embodiment, determining the re-adjustment amount of the first mounting point based on the corresponding relationship and according to the first initial adjustment amount of the flushness and the second initial adjustment amount of the flushness includes:

[0103] The second adjustment amount of the first installation point is calculated as [1+D3+(-1)*E3]*(D2-E2), wherein D3 is the change distance of the front end of the modeling surface line segment along the vertical modeling surface when the projection point changes one unit along the vertical modeling surface based on the corresponding relationship, and the change distance of the rear end of the modeling surface line segment along the vertical modeling surface when the projection point changes one unit along the vertical modeling surface based on the corresponding relationship. D2 is the initial adjustment amount of the first face difference, and E2 is the initial adjustment amount of the second face difference.

[0104] Step S207: determining a first mounting point adjustment amount of the first mounting point according to the first mounting point and the first mounting point re-adjustment amount.

[0105] In one embodiment, determining the first mounting point adjustment amount of the first mounting point according to the first mounting point and the second adjustment amount of the first mounting point includes:

[0106] Determine a first mounting point adjustment amount of the first mounting point as the sum of the first mounting point initial adjustment amount and the first mounting point re-adjustment amount.

[0107] Step S208, determining the actual adjusted thickness of the gasket at the first mounting point according to the first mounting point adjustment amount, determining the actual adjusted thickness of the gasket at the second mounting point according to the second mounting point adjustment amount, and determining the actual adjusted thickness of the gasket at the third mounting point according to the third mounting point adjustment amount.

[0108] Specifically, first execute step S201, based on the scanning data of the door inner panel reinforcement, the door outer panel and the outer handle, construct an installation plane passing through the installation point on the door inner panel reinforcement, construct a through-hole straight line extending along the outer handle installation hole of the door outer panel, and construct a styling surface line segment consistent with the outer handle styling surface of the outer handle. The installation point includes a first installation point, a second installation point and a third installation point. The projection point of the first installation point on the extension line of the styling surface line segment is located outside the styling surface line segment, and the projection line passing through the line connecting the second installation point and the third installation point intersects with the styling surface line segment, and the intersection point is on the styling surface line segment.

[0109] Specifically, the scanning coordinate system of the inner panel reinforcement, the scanning coordinate system of the outer panel surface, and the scanning coordinate system of the outer handle molding surface constructed by scanning data are unified into an overall three-dimensional coordinate system through the corresponding theoretical 3D digital model coordinate system. Then, in the same three-dimensional coordinate system, a plane passing through multiple installation points of the inner panel reinforcement is constructed, which is defined as: the installation plane. A straight line along the X direction / left and right direction of the outer handle mounting hole on the outer panel surface is constructed, which is defined as: the through-hole straight line. A straight line along the X direction / left and right direction of the outer handle molding surface is selected, and a molding surface line segment consistent with the outer handle molding surface is cut out from the straight line. Among them, the front end of the molding surface line segment coincides with the front end of the outer handle molding surface, and the rear end of the molding surface line segment coincides with the rear end of the outer handle molding surface.

[0110] Among them, Figure 5 As shown, the mounting points include a first mounting point A, a second mounting point B, and a third mounting point C. Figure 8 The figure shows a simplified spatial diagram of the installation plane and the modeling surface line segment. Fig. 9 The figure is a simplified diagram of the relationship between the projection of the installation point and the modeling surface line segment on a cross section passing through the modeling surface line segment and parallel to the vertical modeling surface.

[0111] Among them, Figure 8 and Fig. 9 As shown, the projection point A' of the first installation point A projected onto the extended line of the modeling surface segment is located outside the modeling surface segment DE. Specifically, a straight line is made through the first installation point A and perpendicular to the modeling surface segment DE. The point where the straight line intersects with the modeling surface segment DE is the projection point A' of the first installation point A projected onto the extended line of the modeling surface segment. The projection line of the line connecting the second installation point and the third installation point is specifically: a vertical plane is made through the line connecting the second installation point B and the third installation point C and perpendicular to the outer handle modeling surface. The straight line intersecting the outer handle modeling surface is the projection line of the line connecting the second installation point and the third installation point. The projection line intersects with the modeling surface segment DE at a point F on the modeling surface segment, namely the intersection point F. When adding or reducing gaskets at the first installation point A, the outer handle modeling surface will be driven to rotate around the BC line.

[0112] Then execute step S202, calculate the difference between the through hole straight line and the front end of the modeling surface segment along the vertical modeling surface as the first surface difference, and calculate the difference between the through hole straight line and the rear end of the modeling surface segment along the vertical modeling surface as the second surface difference.

[0113] The surface difference includes positive difference and negative difference. When the outer handle moves toward the inside of the car, it becomes a negative difference, that is, the point of the outer handle is recessed into the sheet metal of the outer door panel. When the outer handle moves toward the outside of the car, it becomes a positive difference, that is, the point of the outer handle protrudes from the sheet metal of the outer door panel.

[0114] Then, step S203 is executed to determine the corresponding change relationship between the front end of the modeling surface segment, the rear end of the modeling surface segment and the distance of the projection point along the vertical modeling surface through the spatial position relationship between the installation plane and the modeling surface segment;

[0115] The corresponding change relationship between the front end of the modeling surface line segment, the rear end of the modeling surface line segment and the projection point along the vertical modeling surface distance is used as the corresponding change relationship between the front end of the modeling surface line segment, the rear end of the modeling surface line segment and the first installation point on the installation plane along the vertical modeling surface distance.

[0116] Specifically, the change in the distance of the projection point along the vertical modeling surface directly corresponds to the change in the distance of the first installation point A along the vertical modeling surface, and the remaining installation points can be changed accordingly based on the change of the first installation point.

[0117] In one embodiment, the determining of the corresponding change relationship between the front end of the modeling surface segment, the rear end of the modeling surface segment and the distance of the projection point along the vertical modeling surface through the spatial position relationship between the installation plane and the modeling surface segment includes:

[0118] The corresponding change relationship between the front end of the modeling surface segment and the distance of the projection point along the vertical modeling surface is determined as follows:

[0119] A'F / DF=A'A" / DD', wherein A'F is the distance between the projection point and the intersection point, DF is the distance between the front end of the modeling surface segment and the intersection point, A'A" is the change distance of the projection point along the vertical modeling surface, DD' is the change distance of the front end of the modeling surface segment along the vertical modeling surface, and the change direction of the front end of the modeling surface segment and the projection point along the vertical modeling surface is the same;

[0120] Determine the corresponding change relationship of the distance between the front end of the modeling surface line segment and the rear end of the modeling surface line segment along the vertical modeling surface as follows:

[0121] DF / EF=DD' / EE', wherein EF is the distance between the rear end of the modeling surface segment and the intersection, EE' is the changing distance of the rear end of the modeling surface segment along the vertical modeling surface, and the changing directions of the front end of the modeling surface segment and the rear end of the modeling surface segment along the vertical modeling surface are opposite.

[0122] like Figure 8 As shown, through the spatial relationship between the installation plane (i.e., the triangular plane) and the straight line, the relationship between the normal distances between the front and rear end points of the modeling surface line segment DE and the three points of the installation plane can be calculated:

[0123] A'F / DF=A'A" / DD', wherein A'F is the distance between the projection point and the intersection point, DF is the distance between the front end of the modeling surface segment and the intersection point, A'A" is the change distance of the projection point along the vertical modeling surface, A" is the position of the projection point A' after the change along the vertical modeling surface, DD' is the change distance of the front end of the modeling surface segment along the vertical modeling surface, and D' is the position of the front end D of the modeling surface segment after the change along the vertical modeling surface;

[0124] DF / EF=DD' / EE', wherein EF is the distance between the rear end of the modeling surface segment and the intersection point, EE' is the change distance of the rear end of the modeling surface segment along the vertical modeling surface, and E' is the position of the rear end E of the modeling surface segment after the change along the vertical modeling surface.

[0125] As an example, we can measure the length of A'F to be 247 mm and the length of DF to be 130 mm. Let A'A" be 1, then:

[0126] 247 / 130=1 / DD'

[0127] DD'=130 / 247=0.52

[0128] That is, the ratio of the changing distance of the projection point along the vertical modeling surface to the changing distance of the front end of the modeling surface along the vertical modeling surface is 1:0.52, which can be simplified to 1:0.5.

[0129] In addition, the length of EF can be measured to be 67 mm, so when DD' is 0.5, it can be concluded that:

[0130] 130 / 67=0.5 / EE'

[0131] EE' = 67 / 130*0.5 = 0.25 (67 / 130 is simplified to 0.5)

[0132] Among them, the projection point is close to the front end of the modeling surface segment, and the intersection point is located in the middle of the modeling surface segment. Therefore, the change distance of the projection point along the vertical modeling surface is in the same direction as the change distance of the front end of the modeling surface segment along the vertical modeling surface, and the change distance of the projection point along the vertical modeling surface is in the opposite direction to the change distance of the rear end of the modeling surface segment along the vertical modeling surface. For convenience, the end of the modeling surface segment close to the projection point can be defined as the front end of the modeling surface segment, and the end far from the projection point can be defined as the rear end of the modeling surface segment.

[0133] Based on the above, it can be concluded that the relationship between the change in distance of the projection point A' along the vertical modeling surface and the change in distance of the front end D and the rear end E of the modeling surface segment along the vertical modeling surface is: 1:0.5:-0.25.

[0134] Therefore, the relationship between the change distance of the first installation point A along the vertical modeling surface and the change distance of the front end D and the rear end E of the modeling surface segment along the vertical modeling surface is: 1:0.5:-0.25. The positive and negative signs here represent the relationship between point A plus or minus shims and point DE, positive indicates positive correlation, and negative indicates negative correlation.

[0135] Finally, step S204 is performed to calculate a first mounting point initial adjustment amount of the first mounting point, a second mounting point adjustment amount of the second mounting point, and a third mounting point adjustment amount of the third mounting point according to the first flush and the second flush.

[0136] Specifically, firstly, according to the first flush and the second flush, the first mounting point initial adjustment amount, the second mounting point adjustment amount, and the third mounting point adjustment amount of the third mounting point are calculated. The initial adjustment amount is used to make a preliminary adjustment to the flush.

[0137] In one embodiment, the calculating, according to the first flush and the second flush, a first mounting point initial adjustment amount of the first mounting point, a second mounting point adjustment amount of the second mounting point, and a third mounting point adjustment amount of the third mounting point includes:

[0138] The first mounting point initial adjustment amount of the first mounting point, the second mounting point adjustment amount of the second mounting point, and the third mounting point adjustment amount of the third mounting point are calculated as (D1+E1) / 2, where D1 is the first face difference and E1 is the second face difference.

[0139] In the initial adjustment of this embodiment, the mounting points are adjusted on average. Among them, the "-" sign indicates a reduction in the thickness of the gasket. The "+" sign indicates an increase in the thickness of the gasket. Since the first face difference and the second face difference are signed, the sum of the first face difference and the second face difference can be a positive value or a negative value, so that the adjustment amount may be a positive value or a negative value. When the adjustment amount is a negative value, it indicates a reduction in the thickness of the gasket, and when the adjustment amount is a positive value, it indicates an increase in the thickness of the gasket. After adding the gasket, the outer handle moves toward the inside of the car, which will reduce the face difference, and after reducing the gasket, the outer handle will move toward the outside of the car, and the face difference will increase. Setting the adjustment amount to (D1+E1) / 2 means eliminating the average value of the sum of the first face difference and the second face difference.

[0140] Then, step S205 is performed to calculate a first initial adjustment amount of the first flush and a second initial adjustment amount of the second flush according to the first installation point initial adjustment amount, the second installation point adjustment amount, and the third installation point adjustment amount.

[0141] Specifically, after the initial adjustment amount is determined, the influence of the initial adjustment amount on the two flushes is determined to obtain the first flush initial adjustment amount and the second flush initial adjustment amount.

[0142] Since the first mounting point initial adjustment amount, the second mounting point adjustment amount, and the third mounting point adjustment amount are the same, in some embodiments, the first flush initial adjustment amount is equal to the first flush minus the first mounting point initial adjustment amount, and the second flush initial adjustment amount is equal to the second flush minus the first mounting point initial adjustment amount.

[0143] Then, step S206 is performed to determine the first mounting point re-adjustment amount based on the corresponding relationship and the first flush initial adjustment amount and the second flush initial adjustment amount.

[0144] Since the projection point of the first mounting point is outside the modeling surface line segment, the first mounting point can be adjusted separately to make the modeling surface rotate around the projection line of the line connecting the second mounting point and the third mounting point, thereby adjusting the first flush and the second flush. According to the corresponding change relationship between the front end of the modeling surface line segment, the rear end of the modeling surface line segment and the first mounting point on the mounting plane along the vertical modeling surface distance, the change amount of the first mounting point along the vertical modeling surface distance can be determined as the re-adjustment amount of the first mounting point.

[0145] In one embodiment, determining the re-adjustment amount of the first mounting point based on the corresponding relationship and according to the first initial adjustment amount of the flushness and the second initial adjustment amount of the flushness includes:

[0146] The second adjustment amount of the first installation point is calculated as [1+D3+(-1)*E3]*(D2-E2), wherein D3 is the change distance of the front end of the modeling surface line segment along the vertical modeling surface when the projection point changes one unit along the vertical modeling surface based on the corresponding relationship, and the change distance of the rear end of the modeling surface line segment along the vertical modeling surface when the projection point changes one unit along the vertical modeling surface based on the corresponding relationship. D2 is the initial adjustment amount of the first face difference, and E2 is the initial adjustment amount of the second face difference.

[0147] Specifically, through the corresponding relationship, it can be determined that when the projection point changes by one unit along the vertical modeling surface, for example, by 1 mm, the change distance of the front end of the modeling surface segment along the vertical modeling surface and the change distance of the rear end of the modeling surface segment along the vertical modeling surface. Since the change direction of the front end of the modeling surface segment and the projection point along the vertical modeling surface are the same, and the change direction of the front end of the modeling surface segment and the rear end of the modeling surface segment along the vertical modeling surface are opposite, it is necessary to multiply by -1 before E3. After calculating 1+D3+(-1)*E3, multiply the sum by (D2-E2) to obtain the re-adjustment amount of the first installation point.

[0148] Then, step S207 is executed to determine the first mounting point adjustment amount of the first mounting point according to the first mounting point and the first mounting point re-adjustment amount.

[0149] Specifically, after the re-adjustment amount of the first mounting point is determined, the first mounting point adjustment amount of the first mounting point is determined according to the first mounting point and the re-adjustment amount of the first mounting point.

[0150] In one embodiment, determining the first mounting point adjustment amount of the first mounting point according to the first mounting point and the second adjustment amount of the first mounting point includes:

[0151] Determine a first mounting point adjustment amount of the first mounting point as the sum of the first mounting point initial adjustment amount and the first mounting point re-adjustment amount.

[0152] Specifically, the second adjustment amount of the first mounting point and the initial adjustment amount of the first mounting point are summed to obtain the first mounting point adjustment amount. Meanwhile, the second mounting point adjustment amount and the third mounting point adjustment amount are kept unchanged.

[0153] As an example of the present invention, the relationship between the change in distance of the projection point A' along the vertical modeling surface and the change in distance of the front end D and the rear end E of the modeling surface segment along the vertical modeling surface is 1:0.5:-0.25. The description of each case is as follows:

[0154]

[0155]

[0156]

[0157]

[0158]

[0159]

[0160]

[0161]

[0162] Note: Explanation of the ± sign for the calculation results of step 1 and step 2: If the final result value is: negative: it means reducing the gasket, positive: it means increasing the gasket;

[0163] Regarding adding gaskets: if the outer handle moves toward the inside of the car, it becomes a negative difference (the outer handle is recessed into the outer door sheet); if the gaskets are reduced: if the outer handle moves toward the outside of the car, it becomes a positive difference (the outer handle protrudes from the outer door sheet);

[0164] The above units are all mm.

[0165] Finally, execute step S208, determine the actual adjusted thickness of the gasket at the first mounting point according to the first mounting point adjustment amount, determine the actual adjusted thickness of the gasket at the second mounting point according to the second mounting point adjustment amount, and determine the actual adjusted thickness of the gasket at the third mounting point according to the third mounting point adjustment amount.

[0166] Specifically, since the thickness of the gasket can be unified, after the final adjustment amount of each installation point is obtained, the actual thickness of the added gasket can be calculated.

[0167] In some embodiments, the actual adjusted thickness of the shim is the standard shim thickness plus the final adjustment amount.

[0168] The standard gasket thickness is the gasket thickness determined when the mounting point was originally designed. The final adjustment amount can be a positive value or a negative value. When it is a positive value, the gasket is added to the standard gasket thickness. When it is a negative value, the gasket is reduced from the standard gasket thickness.

[0169] like Fig.10 The diagram shows the schematic diagram of adding gaskets, which are fixed at the first mounting point A, the second mounting point B, and the third mounting point C by bolts 7 and nuts 5. There is a gap between the nut 5 and the inner plate reinforcement 2 for placing the gasket 6. The standard of the gap is 7 mm. Therefore, the standard gasket thickness is 7 mm. When the final adjustment amount of the mounting point is 0, the actual adjustment thickness of the gasket at the mounting point is the standard gasket thickness, that is, 7 mm. When the final adjustment amount is a positive value, the actual adjustment thickness of the gasket is increased on the basis of the standard gasket thickness, and when the final adjustment amount is a negative value, the actual adjustment thickness of the gasket is reduced on the basis of the standard gasket thickness. Table 1 shows a comparison table of the final adjustment amount and the corresponding actual adjustment thickness of the gasket, where "-" means reducing the gasket and "+" means adding the gasket. The unit of Table 1 is mm.

[0170] Table 1

[0171] Final adjustment (mm) -4 -3.5 -3 -2.5 -2 -1.5 -1 -0.5 0 Actual adjustment thickness of gasket (mm) 3 3.5 4 4.5 5 5.5 6 6.5 7 Final adjustment (mm) 0.5 1 1.5 2 2.5 3 3.5 4 Actual adjustment thickness of gasket (mm) 7.5 8 8.5 9 9.5 10 10.5 11

[0172] Once the actual adjusted thickness of the shim at each mounting point is determined, it can be displayed on the screen for the operator's convenience.

[0173] like Fig.11 As shown, the outer handle 1 is provided with a hole 12 corresponding to the first mounting point A, a hole 14 corresponding to the second mounting point B, and a hole 13 corresponding to the third mounting point C. The outer handle 1 is fixed to the inner panel reinforcement 2 by bolts 7 and nuts 5, and a gasket 6 is placed between the nuts 5 and the inner panel reinforcement 2.

[0174] In this embodiment, for the case of three installation points, the change relationship between the installation point and the front and rear ends of the modeling surface line segment is determined to quickly determine the gasket adjustment thickness of each installation point, so that the operator can quickly adjust the installation point.

[0175] like Fig.12 The figure shows a working flow chart of a method for installing an outer door handle according to an embodiment of the present invention, comprising:

[0176] Step S1201, placing and fixing the door sheet metal;

[0177] Step S1202, scanning the door inner panel reinforcement to obtain scanning data of the door inner panel reinforcement;

[0178] Step S1203, scanning the outer handle and the outer panel of the door to obtain scanning data of the outer handle and the outer panel of the door;

[0179] Step S1204, using the above-mentioned method for determining the deviation of the outer door handle to calculate the thickness of the gasket that needs to be adjusted at each installation point;

[0180] Step S1205, adjusting the thickness of the gasket at each installation point, and fastening the outer handle to the door inner panel reinforcement, thereby completing the installation of the outer handle.

[0181] like Fig.13 The figure shows a flushness measuring device used in an embodiment of the present invention, including: a first scanning device 131 for scanning the precision of the inner panel reinforcement and a second device 132 for scanning the precision of the door outer panel and the precision of the outer handle. The first scanning device 131 and the second scanning device 132 are connected to the controller 133 in communication. The controller 133 is provided with a screen 1331, a human-machine interface (HMI) 1332, an IPS (CCR: Spec info) 1333, and a database (Data Storge) 1334. The controller 133 obtains the scanning data of the inner panel reinforcement of the vehicle door from the first scanning device 131, obtains the scanning data of the outer panel of the vehicle door and the outer handle from the second scanning device 131, and executes the method for determining the deviation of the outer handle of the vehicle door as described above, obtains the gasket thickness that needs to be adjusted for each installation point, and displays it on the screen 1331 through the human-machine interface system. The database 1334 is responsible for storing the gasket data of each vehicle outer handle for easy traceability. The most accurate vehicle body deviation value is obtained by fitting and calculating the data of the first scanning device 131 and the second scanning device 132 .

[0182] The first scanning device 131 is suspended on a track 135 of a door subassembly line 134. The first scanning device 131 can be raised and lowered to achieve up and down scanning.

[0183] like Fig.13 and Fig.14 As shown, the second scanning device 132 is installed on the slide rail 136 of the hanging hand 135, and can slide on the slide rail 136 to achieve left and right movement scanning, and the slide rail 136 is fixed on the car door dispensing platform 137 to achieve up and down movement scanning.

[0184] Specifically, the installation method of the door handle includes:

[0185] 1. After the preparation of man-machine-material method (4M) is completed before the operation, the door sheet metal is placed on the door assembly trolley / stand and fixed

[0186] 2. Start the operation; the operator only needs to press the start button of the first scanning device 131, and the first scanning device 131 will descend to the set height and scan the inner door panel. When the device emits a "beep / beep / beep, scanning completed, please place the outer handle on the fixture next" sound, the handle can be put back to its original position and the next operation can be carried out.

[0187] 3. The operator places the external handle on the special external handle fixing fixture on the door stand;

[0188] 4. The operator presses a button to start the second scanning device 132. The second scanning device 132 will scan the external handle and the outer panel of the door (at the external handle) along the path set by the system. When the device makes a "beep / beep / beep, please add a gasket according to the model displayed on the screen" sound, it means that the scanning is completed;

[0189] 5. After completing the above steps, the operator only needs to wait for about 3 seconds. The system will automatically calculate the thickness of the gaskets to be added to the three installation points based on the first face difference and the second face difference, and then display the gasket model and gasket color to be added to each installation point on the display screen (the different thicknesses of the gaskets are distinguished by different colors of coatings, and each gasket box 138 is marked with the gasket model);

[0190] 6. The operator places the gasket into the outer handle according to the instructions on the screen, and fastens the outer handle to the inner door panel according to the operation instructions;

[0191] 7. After completing the installation of the external handle, the operator will proceed to install the next door part.

[0192] This embodiment can automatically calculate the gasket of each installation point based on the scan data of the door inner panel reinforcement, the door outer panel and the outer handle, which is convenient for the operator to work and enables the operator to complete the work quickly and ensure the surface difference accuracy.

[0193] It should be understood that the order of execution of the steps in the above embodiment does not necessarily mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiment of the present invention.
