Background Technology

[0002] External door handles have become standard equipment, and more and more cars are adopting external door handle designs. According to styling requirements, the surface difference between the external door handle and the outer door panel must be zero, which is a first-level appearance surface of the whole vehicle and the only first-level appearance surface of the door to be evaluated.

[0003] However, in actual installation of external handles, there is a surface difference between the external handle and the outer door panel. When installing, the operator relies solely on experience to install shims to adjust the surface difference, resulting in low work efficiency. Summary of the Invention

[0004] Based on this, it is necessary to address the technical problem of low work efficiency caused by the existing technology of installing shims based on experience to adjust the surface difference between the outer handle and the outer door panel, and to provide a method for determining the deviation of the outer door handle, a method for adjusting the deviation of the outer door handle, electronic equipment, storage medium and computer program products.

[0005] This invention provides a method for determining the deviation of an exterior door handle, wherein the exterior door handle is installed on a reinforcement member of the interior door panel, and the shaped surface of the exterior door handle is located in an exterior door handle mounting hole on the exterior door panel surface, comprising:

[0006] Based on the scanning data of the inner door panel reinforcement, the outer door panel, and the outer handle, an installation plane passing through the mounting point on the inner door panel reinforcement is constructed, a through hole line extending along the outer handle mounting hole on 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.

[0007] The difference between the front end of the through hole line and the front end of the shaped surface segment along the vertical shaped surface is calculated as the first surface difference, and the difference between the rear end of the through hole line and the shaped surface segment along the vertical shaped surface is calculated as the second surface difference.

[0008] Based on the spatial relationship between the mounting plane and the shaped surface line segment, the corresponding changes in the distance between the front end of the shaped surface line segment, the rear end of the shaped surface line segment, and the mounting point on the mounting plane along the perpendicular shaped surface are determined;

[0009] Based on the first surface difference, the second surface difference, and the corresponding change relationship, the gasket thickness that needs to be adjusted for each mounting point is calculated.

[0010] Further, the mounting points include a first mounting point, a second mounting point, and a third mounting point. The projection point of the first mounting point onto the extension line of the sculpted surface segment is located outside the sculpted surface segment. The projection line of the line connecting the second mounting point and the third mounting point intersects the sculpted surface segment, and the intersection point is on the sculpted surface segment. Determining the corresponding change in distance along the perpendicular sculpted surface between the front end and rear end of the sculpted surface segment and the mounting point on the mounting plane based on the spatial positional relationship between the mounting plane and the sculpted surface segment includes:

[0011] By determining the spatial relationship between the mounting plane and the shape surface line segment, the corresponding changes in the distance between the front end of the shape surface line segment, the rear end of the shape surface line segment, and the projection point along the perpendicular shape surface are determined;

[0012] The corresponding relationship between the front end of the shaped surface segment, the rear end of the shaped surface segment, and the projection point along the vertical shaped surface is taken as the corresponding relationship between the front end of the shaped surface segment, the rear end of the shaped surface segment, and the first mounting point on the mounting plane along the vertical shaped surface.

[0013] Furthermore, determining the corresponding changes in the distances between the front end and rear end of the shape surface segment and the projection point along the perpendicular shape surface based on the spatial positional relationship between the mounting plane and the shape surface segment includes:

[0014] The corresponding relationship between the front end of the shaped surface line segment and the projection point along the perpendicular shaped surface is determined as follows:

[0015] A'F / DF=A'A” / DD', where 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;

[0016] The corresponding relationship between the distances between the front end and the rear end of the sculpted surface segment along the perpendicular sculpted surface is determined as follows:

[0017] DF / EF = DD' / EE', where EF is the distance between the rear end of the styling surface segment and the intersection point, EE' is the change distance of the rear end of the styling surface segment along the vertical styling surface, and the change direction of the front end of the styling surface segment along the vertical styling surface is opposite to that of the rear end of the styling surface segment.

[0018] Furthermore, the step of calculating the required gasket thickness adjustment for each mounting point based on the first surface difference, the second surface difference, and the corresponding change relationship includes:

[0019] Based on the first surface difference and the second surface difference, calculate the initial adjustment amount of the first installation point, the adjustment amount of the second installation point, and the adjustment amount of the third installation point;

[0020] Based on the initial adjustment amount of the first installation point, the adjustment amount of the second installation point, and the adjustment amount of the third installation point, calculate the initial adjustment amount of the first surface difference and the initial adjustment amount of the second surface difference.

[0021] Based on the aforementioned correspondence, the adjustment amount of the first mounting point is determined according to the first initial adjustment amount of the surface difference and the second initial adjustment amount of the surface difference.

[0022] Based on the first installation point and the adjustment amount of the first installation point again, determine the first installation point adjustment amount;

[0023] The actual adjustment thickness of the shim at the first mounting point is determined based on the adjustment amount at the first mounting point, the actual adjustment thickness of the shim at the second mounting point is determined based on the adjustment amount at the second mounting point, and the actual adjustment thickness of the shim at the third mounting point is determined based on the adjustment amount at the third mounting point.

[0024] Furthermore, the step of calculating the initial adjustment amount of the first mounting point, the adjustment amount of the second mounting point, and the adjustment amount of the third mounting point based on the first surface difference and the second surface difference includes:

[0025] The initial adjustment amount of the first installation point, the adjustment amount of the second installation point, and the adjustment amount of the third installation point are calculated as (D1+E1) / 2, where D1 is the first surface difference and E1 is the second surface difference.

[0026] Furthermore, the step of determining the readjustment amount of the first mounting point based on the correspondence, according to the first initial adjustment amount of the surface difference and the second initial adjustment amount of the surface difference, includes:

[0027] The adjustment amount of the first installation point is calculated as [1+D3+(-1)*E3]*(D2-E2), where D3 is the distance the front end of the modeling surface segment changes along the vertical modeling surface when the projection point changes by one unit along the vertical modeling surface, and the distance the rear end of the modeling surface segment changes along the vertical modeling surface when the projection point changes by one unit along the vertical modeling surface, determined based on the correspondence. D2 is the initial adjustment amount of the first surface difference, and E2 is the initial adjustment amount of the second surface difference.

[0028] Furthermore, determining the first installation point adjustment amount based on the first installation point and the readjustment amount of the first installation point includes:

[0029] The adjustment amount of the first installation point is determined to be the sum of the initial adjustment amount of the first installation point and the subsequent adjustment amount of the first installation point.

[0058] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. Identical components are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0059] like Figure 1 The diagram shows a flowchart of a method for determining the deviation of an exterior door handle according to an embodiment of the present invention. The exterior door handle is installed on a reinforcement member of the interior door panel, and the shaped surface of the exterior door handle is located in the exterior door panel mounting hole on the exterior door panel surface. The method includes:

[0060] Step S101: Based on the scanning data of the inner door panel reinforcement, the outer door panel, and the outer handle, construct an installation plane passing through the mounting point on the inner door panel reinforcement, construct a through hole straight line extending along the outer handle mounting hole on the outer door panel, and construct a styling surface line segment consistent with the outer handle styling surface of the outer handle.

[0061] Step S102: Calculate the difference between the front end of the through hole line and the front end of the shaped surface segment along the vertical shaped surface as the first surface difference, and calculate the difference between the rear end of the through hole line and the shaped surface segment along the vertical shaped surface as the second surface difference.

[0062] Step S103: Based on the spatial positional relationship between the mounting plane and the shaped surface line segment, determine the corresponding change relationship of the distance between the front end of the shaped surface line segment, the rear end of the shaped surface line segment and the mounting point on the mounting plane along the perpendicular shaped surface.

[0063] Step S104: Based on the first surface difference, the second surface difference, and the corresponding change relationship, calculate the gasket thickness that needs to be adjusted for each mounting point.

[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 exterior door handle 1 is mounted on the interior door panel reinforcement 2, which can be fixed to the interior door panel 4. The shaped surface 11 of the exterior door handle 1 is positioned within the exterior door panel surface 3's exterior door handle mounting hole 31. According to the styling requirements, the surface difference between the shaped surface 11 and the outer surface of the exterior door panel 3 is 0 ± 1.0 mm. Each mounting point is bolted to the interior door panel reinforcement 2 using bolts and nuts 5. Washers 6 are fitted onto the bolts 5. To meet the styling requirements, the thickness of the washers 6 at the mounting points needs to be adjusted.

[0066] After obtaining the scanning data of the inner door panel reinforcement, the outer door panel, and the outer handle, step S101 is executed. Based on the scanning data of the inner door panel reinforcement, the outer door panel, and the outer handle, an installation plane passing through the mounting point on the inner door panel reinforcement is constructed, a through hole line extending along the outer handle mounting hole on the outer door panel is constructed, and a shaped surface line segment consistent with the outer handle shaped surface of the outer handle is constructed.

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

[0068] The scanning coordinate system of the inner panel reinforcement is constructed based on the scanning data of the inner panel reinforcement, the scanning coordinate system of the outer panel surface is constructed based on the scanning data of the outer panel surface, and the scanning coordinate system of the outer handle shaped surface is constructed based on the scanning data of the outer handle shaped surface.

[0069] Obtain the numerator coordinate system of the inner plate reinforcement, the numerator coordinate system of the outer plate surface, and the numerator coordinate system of the outer handle shape surface;

[0070] Align the scanning coordinate system of the inner plate reinforcement with the digital model coordinate system of the inner plate reinforcement, align the scanning coordinate system of the outer plate surface with the digital model coordinate system of the outer plate surface, and align the scanning coordinate system of the outer handle shaped surface with the digital model coordinate system of the outer handle shaped surface.

[0071] The scanning coordinate system of the inner plate reinforcement, the scanning coordinate system of the outer plate surface, and the scanning coordinate system of the outer handle shape surface are integrated into the same three-dimensional coordinate system, and the coordinates of the three scanning coordinate systems are transformed into coordinates in the same three-dimensional coordinate system.

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

[0073] Specifically, the first step is to construct a scanning coordinate system, including:

[0074] Three points (not limited to mounting points and feature points) of the inner plate reinforcement are selected to construct a scanning coordinate system (coordinates X1, Y1, Z1) for the inner plate reinforcement;

[0075] Select three points on the outer panel surface (not limited to installation points and feature points) to construct a scanning coordinate system for the outer panel surface (coordinates X2, Y2, Z2).

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

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

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

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

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

[0081] Then, the scanned parts are assembled using a coordinate system. Specifically, based on the principle of aligning the scanned surface of the same part with the coordinate system of the theoretical 3D model, the same points in the scanned coordinate systems of the three parts are aligned with the same points of the same parts in the 3D model coordinate system and assembled together. This unifies the three scanned coordinate systems into a unified three-dimensional coordinate system.

[0082] Finally, construct a plane passing through multiple mounting points of the inner panel reinforcement, defined as the mounting plane. Construct a straight line along the X-direction / left-right direction for the outer handle mounting holes on the outer panel, defined as the through-hole line. Select a straight line along the X-direction / left-right direction on the outer handle's shaped surface, and extract a shaped surface segment from this line that coincides with the outer handle's shaped surface. The front end of this shaped surface segment coincides with the front end of the outer handle's shaped surface, and the rear end of the shaped surface segment coincides with the rear end of the outer handle's shaped surface.

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

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

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

[0086] The difference between the front end of the through hole line and the shaped surface line segment along the vertical shaped surface is taken as the first surface difference, and the difference between the rear end of the through hole line and the shaped surface line segment along the vertical shaped surface is taken as the second surface difference.

[0087] Then, step S103 is executed, and the corresponding changes in the distance between the front end of the shaped surface segment, the rear end of the shaped surface segment, and the installation point on the mounting plane along the vertical shaped surface are determined by the spatial positional relationship between the mounting plane and the shaped surface segment.

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

[0089] Finally, step S104 is executed to calculate the gasket thickness that needs to be adjusted for each mounting point based on the first surface difference, the second surface difference, and the corresponding change relationship.

[0090] Specifically, after determining the gasket thickness, the work instruction screen displays that multiple installation points require the addition of gaskets of different thicknesses and types.

[0091] This invention constructs an installation plane passing through the mounting point on the inner door panel reinforcement, constructs a through-hole straight line extending along the outer door panel mounting hole, constructs a shaped surface line segment consistent with the outer handle shaped surface of the outer handle, and determines the shim thickness that needs to be adjusted at each mounting point through the spatial positional relationship between the installation surface and the shaped surface line segment. This allows the operator to directly adjust the shim thickness according to the prompts when installing the outer handle, thus quickly completing the work.

[0092] like Figure 2 The diagram shows a flowchart of a method for determining the deviation of an exterior door handle according to another embodiment of the present invention. The exterior door handle is installed on a door inner panel reinforcement, and the shaped surface of the exterior door handle is placed in the exterior door panel mounting hole on the exterior door panel surface. The method includes:

[0093] Step S201: Based on the scanning data of the inner door panel reinforcement, the outer door panel, and the outer handle, construct an installation plane passing through the mounting points on the inner door panel reinforcement, construct a through-hole straight line extending along the outer handle mounting hole on the outer door panel, and construct a styling surface line segment consistent with the outer handle styling surface of the outer handle. The mounting points include a first mounting point, a second mounting point, and a third mounting point. The projection point of the first mounting point on the extension line of the styling surface line segment is located outside the styling surface line segment. The projection line of the line connecting the second mounting point and the third mounting point intersects the styling surface line segment, and the intersection point is on the styling surface line segment.

[0094] Step S202: Calculate the difference between the front end of the through hole line and the front end of the shaped surface segment along the vertical shaped surface as the first surface difference, and calculate the difference between the rear end of the through hole line and the shaped surface segment along the vertical shaped surface as the second surface difference.

[0095] Step S203: Based on the spatial positional relationship between the mounting plane and the shaped surface line segment, determine the corresponding change relationship between the front end of the shaped surface line segment, the rear end of the shaped surface line segment, and the projection point along the perpendicular shaped surface.

[0096] The corresponding relationship between the front end of the shaped surface segment, the rear end of the shaped surface segment, and the projection point along the vertical shaped surface is taken as the corresponding relationship between the front end of the shaped surface segment, the rear end of the shaped surface segment, and the first mounting point on the mounting plane along the vertical shaped surface.

[0097] Step S204: Based on the first surface difference and the second surface difference, calculate the initial adjustment amount of the first installation point, the adjustment amount of the second installation point, and the adjustment amount of the third installation point.

[0098] In one embodiment, calculating the initial adjustment amount of the first mounting point, the adjustment amount of the second mounting point, and the adjustment amount of the third mounting point based on the first surface difference and the second surface difference includes:

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

[0100] Step S205: Calculate the initial adjustment amount of the first surface difference and the initial adjustment amount of the second surface difference based on the initial adjustment amount of the first installation point, the adjustment amount of the second installation point, and the adjustment amount of the third installation point.

[0101] Step S206: Based on the correspondence, determine the first installation point adjustment amount again according to the first surface difference initial adjustment amount and the second surface difference initial adjustment amount.

[0102] In one embodiment, determining the readjustment amount of the first mounting point based on the correspondence, according to the first initial adjustment amount of the surface difference and the second initial adjustment amount of the surface difference, includes:

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

[0104] Step S207: Determine the first installation point adjustment amount based on the first installation point and the first installation point readjustment amount.

[0105] In one embodiment, determining the first mounting point adjustment amount based on the first mounting point and the first mounting point readjustment amount includes:

[0106] The adjustment amount of the first installation point is determined to be the sum of the initial adjustment amount of the first installation point and the subsequent adjustment amount of the first installation point.

[0107] Step S208: Determine the actual adjustment thickness of the shim at the first mounting point based on the adjustment amount at the first mounting point; determine the actual adjustment thickness of the shim at the second mounting point based on the adjustment amount at the second mounting point; and determine the actual adjustment thickness of the shim at the third mounting point based on the adjustment amount at the third mounting point.

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

[0109] Specifically, the scanning coordinate systems of the inner panel reinforcement, the outer panel surface, and the outer handle shape surface, constructed using scanning data, are unified into a single three-dimensional coordinate system through the corresponding theoretical 3D digital model coordinate system. Then, within this same three-dimensional coordinate system, a plane passing through multiple mounting points of the inner panel reinforcement is constructed, defined as the mounting plane. A straight line along the X-direction / left-right direction of the outer handle mounting hole on the outer panel surface is constructed, defined as the through-hole line. A straight line along the X-direction / left-right direction of the outer handle shape surface is selected, and a shape surface segment consistent with the outer handle shape surface is extracted from this line. The front end of the shape surface segment coincides with the front end of the outer handle shape surface, and the rear end of the shape surface segment coincides with the rear end of the outer handle shape surface.

[0110] Among them, such as Figure 5 As shown, the mounting points include a first mounting point A, a second mounting point B, and a third mounting point C, as follows. Figure 8 The diagram shown is a simplified spatial representation of the installation plane and the line segments of the shaped surface. Figure 9 This is a simplified diagram showing the relationship between the projection of the mounting point and the line segment of the shape surface on a cross-section that passes through the shape surface line segment and is parallel to the perpendicular shape surface.

[0111] Among them, such as Figure 8 and Figure 9 As shown, the projection point A' of the first mounting point A onto the extension line of the styling surface segment DE is located outside the styling surface segment DE. Specifically, a straight line passing through the first mounting point A and perpendicular to the styling surface segment DE is drawn, and the point where this straight line intersects the styling surface segment DE is the projection point A' of the first mounting point A onto the extension line of the styling surface segment DE. The projection line passing through the line connecting the second mounting point and the third mounting point is specifically: a vertical plane passing through the line connecting the second mounting point B and the third mounting point C and perpendicular to the outer handle styling surface is drawn, and the straight line intersecting this vertical plane with the outer handle styling surface is the projection line of the line connecting the second and third mounting points. The projection line intersects the styling surface segment DE at a point F on the styling surface segment, i.e., the intersection point F. When a shim is added or removed at the first mounting point A, the outer handle styling surface will rotate around the line connecting BC.

[0112] Then, step S202 is executed, calculating the difference between the front end of the through hole line and the front end of the shaped surface segment along the vertical shaped surface as the first surface difference, and calculating the difference between the rear end of the through hole line and the shaped surface segment along the vertical shaped surface as the second surface difference.

[0113] Among these, surface differences include positive and negative differences. When the outer handle moves inward towards the vehicle, it becomes a negative difference, meaning that point of the outer handle is recessed into the outer panel of the door. When the outer handle moves outward towards the vehicle, it becomes a positive difference, meaning that point of the outer handle protrudes from the outer panel of the door.

[0114] Then, step S203 is executed to determine the corresponding changes in the distance between the front end of the shaped surface segment, the rear end of the shaped surface segment, and the projection point along the vertical shaped surface by means of the spatial positional relationship between the mounting plane and the shaped surface segment.

[0115] The corresponding relationship between the front end of the shaped surface segment, the rear end of the shaped surface segment, and the projection point along the vertical shaped surface is taken as the corresponding relationship between the front end of the shaped surface segment, the rear end of the shaped surface segment, and the first mounting point on the mounting plane along the vertical shaped surface.

[0116] Specifically, the change in distance of the projection point along the vertical shaping surface directly corresponds to the change in distance of the first mounting point A along the vertical shaping surface, while the other mounting points can be changed accordingly based on the change of the first mounting point.

[0117] In one embodiment, determining the corresponding changes in the distances between the front end and rear end of the shape surface segment and the projection point along the perpendicular shape surface based on the spatial positional relationship between the mounting plane and the shape surface segment includes:

[0118] The corresponding relationship between the front end of the shaped surface line segment and the projection point along the perpendicular shaped surface is determined as follows:

[0119] A'F / DF=A'A” / DD', where 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] The corresponding relationship between the distances between the front end and the rear end of the sculpted surface segment along the perpendicular sculpted surface is determined as follows:

[0121] DF / EF = DD' / EE', where EF is the distance between the rear end of the styling surface segment and the intersection point, EE' is the change distance of the rear end of the styling surface segment along the vertical styling surface, and the change direction of the front end of the styling surface segment along the vertical styling surface is opposite to that of the rear end of the styling surface segment.

[0122] like Figure 8 As shown, by analyzing the spatial relationship between the mounting plane (i.e., the triangular plane) and the straight line, the relationship between the normal distances of the two endpoints of the model surface line segment DE and the three points on the mounting plane can be calculated:

[0123] A'F / DF=A'A” / DD', where 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', where EF is the distance between the rear end of the styling surface segment and the intersection point, EE' is the change distance of the rear end of the styling surface segment along the vertical styling surface, and E' is the position of the rear end of the styling surface segment E after the change along the vertical styling surface.

[0125] As an example, the length of A'F can be measured 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 change distance of the projection point along the vertical shaping surface to the change distance of the front end of the shaping surface along the vertical shaping surface is 1:0.52, which can be simplified to 1:0.5.

[0129] Additionally, since the length of EF can be measured to be 67 mm, when DD' is 0.5, we can conclude that:

[0130] 130 / 67=0.5 / EE'

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

[0132] In this design, the projection point is closer to the front end of the shape surface segment, while the intersection point is located in the middle of the shape surface segment. Therefore, the change in distance of the projection point along the vertical shape surface is in the same direction as the change in distance of the front end of the shape surface segment along the vertical shape surface, while the change in distance of the projection point along the vertical shape surface is in the opposite direction to the change in distance of the rear end of the shape surface segment along the vertical shape surface. For convenience, the end of the shape surface segment closer to the projection point can be defined as the front end of the shape surface segment, and the end farther from the projection point can be defined as the rear end of the shape surface segment.

[0133] In summary, the relationship between the change in distance of projection point A' along the vertical shaping surface and the change in distance between the front end D and the rear end E of the shaping surface line segment along the vertical shaping surface is: 1:0.5:-0.25.

[0134] Therefore, the relationship between the change in distance of the first installation point A along the vertical shaping surface and the change in distance of the front end D and the rear end E of the shaping surface line segment along the vertical shaping surface is: 1:0.5:-0.25. The positive and negative signs here indicate the relationship between the addition / subtraction of shims at point A and points DE; positive indicates a positive correlation, and negative indicates a negative correlation.

[0135] Finally, step S204 is executed, and the initial adjustment amount of the first installation point, the adjustment amount of the second installation point, and the adjustment amount of the third installation point are calculated based on the first surface difference and the second surface difference.

[0136] Specifically, firstly, based on the first surface difference and the second surface difference, calculate the initial adjustment amount for the first mounting point, the second mounting point, and the third mounting point. The initial adjustment amount is used for preliminary adjustment of the surface difference.

[0137] In one embodiment, calculating the initial adjustment amount of the first mounting point, the adjustment amount of the second mounting point, and the adjustment amount of the third mounting point based on the first surface difference and the second surface difference includes:

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

[0139] In this embodiment, the installation points are adjusted evenly during the initial adjustment. A "-" sign indicates a reduction in shim thickness, and a "+" sign indicates an increase in shim thickness. Since the first and second surface differences are signed, their sum can be positive or negative, resulting in an adjustment amount that can also be positive or negative. A negative adjustment amount indicates a reduction in shim thickness, while a positive adjustment amount indicates an increase in shim thickness. Increasing the shim causes the outer handle to move inward, reducing the surface difference; conversely, decreasing the shim causes the outer handle to move outward, increasing the surface difference. Setting the adjustment amount to (D1+E1) / 2 represents eliminating the average of the sum of the first and second surface differences.

[0140] Then, step S205 is executed, and the initial adjustment amount of the first surface difference and the initial adjustment amount of the second surface difference are calculated based on the initial adjustment amount of the first installation point, the adjustment amount of the second installation point, and the adjustment amount of the third installation point.

[0141] Specifically, after determining the initial adjustment amount, the impact of the initial adjustment amount on the two surface differences is determined, resulting in the initial adjustment amount for the first surface difference and the initial adjustment amount for the second surface difference.

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

[0143] Then, step S206 is executed, and based on the correspondence, the first installation point is re-adjusted according to the first surface difference initial adjustment amount and the second surface difference initial adjustment amount.

[0144] Since the projection point of the first mounting point is outside the shape surface line segment, the first mounting point can be adjusted independently to rotate the shape surface around the projection line connecting the second and third mounting points, thereby adjusting the first surface difference and the second surface difference. Based on the corresponding changes in the distance between the front end and rear end of the shape surface line segment and the first mounting point on the mounting plane along the perpendicular shape surface, the change in distance of the first mounting point along the perpendicular shape surface can be determined as the adjustment amount for the first mounting point.

[0145] In one embodiment, determining the readjustment amount of the first mounting point based on the correspondence, according to the first initial adjustment amount of the surface difference and the second initial adjustment amount of the surface difference, includes:

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

[0147] Specifically, through the correspondence, the distance the front end and rear end of the shape surface segment change along the vertical shape surface when the projection point changes by one unit (e.g., 1 mm) along the vertical shape surface can be determined. Since the front end of the shape surface segment and the projection point change in the same direction along the vertical shape surface, while the front end and rear end change in opposite directions, -1 needs to be multiplied before E3. After calculating 1 + D3 + (-1) * E3, the summation result is multiplied by (D2 - E2) to obtain the readjustment amount for the first installation point.

[0148] Then, step S207 is executed to determine the first installation point adjustment amount based on the first installation point and the first installation point readjustment amount.

[0149] Specifically, after determining the readjustment amount of the first installation point, the first installation point adjustment amount is determined based on the first installation point and the readjustment amount of the first installation point.

[0150] In one embodiment, determining the first mounting point adjustment amount based on the first mounting point and the first mounting point readjustment amount includes:

[0151] The adjustment amount of the first installation point is determined to be the sum of the initial adjustment amount of the first installation point and the subsequent adjustment amount of the first installation point.

[0152] Specifically, the sum of the initial adjustment amount of the first installation point and the subsequent adjustment amount of the first installation point is used as the adjustment amount of the first installation point. At the same time, the adjustment amounts of the second and third installation points remain unchanged.

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

[0160]

[0161]

[0162] Note: Explanation of ± signs in the calculation results of steps 1 and 2: If the final result value is negative, it means the shim is reduced; if it is positive, it means the shim is added.

[0163] Regarding adding shims: if the outer door handle moves inwards, it becomes a negative difference (the outer door handle is recessed into the outer panel); if the outer door handle moves outwards, it becomes a positive difference (the outer door handle protrudes from the outer panel).

[0164] All units mentioned above are in mm.

[0165] Finally, step S208 is executed, determining the actual adjustment thickness of the shim at the first mounting point based on the adjustment amount at the first mounting point, determining the actual adjustment thickness of the shim at the second mounting point based on the adjustment amount at the second mounting point, and determining the actual adjustment thickness of the shim at the third mounting point based on the adjustment amount at the third mounting point.

[0166] Specifically, since the thickness of the gaskets can be standardized, the actual added gasket thickness can be calculated after obtaining the final adjustment amount at each installation point.

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

[0168] The standard shim thickness is the shim thickness originally determined in the design of the installation point. The final adjustment can be a positive or negative value. When it is positive, a shim is added to the standard shim thickness; when it is negative, a shim is removed from the standard shim thickness.

[0169] like Figure 10 The diagram shows the addition of shims. Mounting points A, B, and C are secured with bolts 7 and nuts 5. A gap exists between nut 5 and inner plate reinforcement 2 for placing shims 6. This gap is 7 mm in diameter. Therefore, the standard shim thickness is 7 mm. When the final adjustment at a mounting point is 0, the actual adjusted shim thickness at that point is the standard shim thickness, which is 7 mm. When the final adjustment is positive, the actual adjusted shim thickness is increased by the standard shim thickness; when the final adjustment is negative, the actual adjusted shim thickness is decreased by the standard shim thickness. Table 1 shows a comparison between a final adjustment and the corresponding actual adjusted shim thickness, where "-" indicates a decrease in shims and "+" indicates an addition of shims. The unit in Table 1 is mm.

[0170] Table 1

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

[0172] Once the actual adjustment thickness of the shims at each installation point is determined, it can be displayed on the screen for the convenience of the operator.

[0173] like Figure 11 As shown, the outer handle 1 has 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 plate reinforcement 2 by bolts 7 and nuts 5, and a washer 6 is placed between the nut 5 and the inner plate reinforcement 2.

[0174] This embodiment addresses the case of three installation points. By determining the relationship between the installation point and the front and rear ends of the shaped surface line segment, the shim adjustment thickness for each installation point can be quickly determined, facilitating the operator to quickly adjust the installation point.

[0175] like Figure 12 The diagram shown is a flowchart of a method for installing an exterior door handle according to an embodiment of the present invention, including:

[0176] Step S1201: Place and fix the door sheet metal;

[0177] Step S1202: Scan the door inner panel reinforcement to obtain the scan data of the door inner panel reinforcement;

[0178] Step S1203: Scan the outer handle and the outer panel of the door to obtain the scan data of the outer handle and the scan data of the outer panel of the door;

[0179] Step S1204: Using the method for determining the deviation of the outer door handle as described above, calculate the shim thickness that needs to be adjusted for each of the installation points;

[0180] Step S1205: Adjust the shim thickness at each mounting point and fasten the outer handle to the door inner panel reinforcement to complete the outer handle installation.

[0181] like Figure 13 The diagram shows the surface difference measuring device used in this embodiment of the invention, comprising: a first scanning device 131 for scanning the accuracy of the inner panel reinforcement and a second device 132 for scanning the accuracy of the outer door panel and the accuracy of the individual outer handle. The first scanning device 131 and the second scanning device 132 are communicatively connected to a controller 133. The controller 133 includes a screen 1331, a human-machine interface (HMI) 1332, an IPS (CCR: Spec info) 1333, and a database 1334. The controller 133 acquires scan data of the inner door panel reinforcement from the first scanning device 131, and scan data of the outer door panel and the outer handle from the second scanning device 131. It then executes the aforementioned method for determining the deviation of the outer door handle to determine the required shim thickness for each installation point, and displays this information on the screen 1331 via the HMI. The database 1334 stores the shim data for each outer door handle for easy traceability. The most accurate vehicle body deviation value is obtained by fitting the data from the first scanning device 131 and the second scanning device 132.

[0182] The first scanning device 131 is suspended on the track 135 of the door assembly line 134. The first scanning device 131 can be raised and lowered to perform vertical scanning.

[0183] like Figure 13 and Figure 14 As shown, the second scanning device 132 is mounted on the slide rail 136 of the handle 135 and can slide on the slide rail 136 to achieve left and right movement scanning, while the slide rail 136 is fixed on the door assembly table 137 to achieve up and down movement scanning.

[0184] Specifically, the methods for installing exterior door handles include:

[0185] 1. After completing the 4M (Man, Machine, Material) preparation before operation, place the door sheet metal on the door assembly trolley / frame and secure it.

[0186] 2. Start the operation; the operator only needs to press the start button of the first scanning device 131. 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, scan complete. Next, please place the outer handle on the fixture," the device can be returned to its original position, and the next operation can be performed.

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

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

[0189] 5. After the above steps are completed, the operator only needs to wait about 3 seconds. The system will automatically calculate the thickness of the gasket to be added to the three installation points based on the first surface difference and the second surface difference. Then, the gasket model and color to be added to each installation point will be displayed on the screen. (Different gasket thicknesses are distinguished by different colored coatings, and the gasket model is marked on each gasket box 138).

[0190] 6. The operator shall insert the shim into the outer handle according to the on-screen instructions, and fasten the outer handle to the inner panel of the door according to the work instructions;

[0191] 7. After the external handle is installed, the operator will proceed with the installation of the next door component.

[0192] This embodiment can automatically calculate the gasket for each installation point based on the scanning data of the inner door panel reinforcement, the outer door panel, and the outer handle, which facilitates the operator's work and enables the operator to complete the work quickly while ensuring surface accuracy.

[0193] It should be understood that the sequence number of each step in the above embodiments does not imply the order of execution.

[0205] This invention constructs an installation plane passing through the mounting point on the inner door panel reinforcement, constructs a through-hole straight line extending along the outer door panel mounting hole, constructs a shaped surface line segment consistent with the outer handle shaped surface of the outer handle, and determines the shim thickness that needs to be adjusted at each mounting point through the spatial positional relationship between the installation surface and the shaped surface line segment.
