[0032] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0033] In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.

[0034] In a first aspect, an embodiment of the present application provides a vehicle door sill section design method.

[0035] In one embodiment, referring to Figure 1 and Figure 4 , Figure 1 This is a flow chart of the first embodiment of the vehicle door sill section design method of this application. Figure 1 As shown in FIG, the vehicle threshold section design method includes:

[0036] S1: Using a pre-set plane perpendicular to the vehicle's X-axis as a reference plane and the position of the sill stop 1 as a reference point, fit the main cross-section of the sill. The fitted main cross-section can be the front or rear sill of the vehicle, and can include the sill and various structures near the sill perimeter. The vehicle's X-axis can be the longitudinal direction of the vehicle.

[0037] S2: Calculate the Y-direction width of the sill guard based on the main cross-section of the sill and the set sill wiring harness radius r. It should be understood that the Y-direction width of the sill guard can be calculated directly based on the main cross-section of the sill and the set sill wiring harness radius r, or it can be calculated indirectly based on the main cross-section of the sill and the set sill wiring harness radius r, where the Y-direction can refer to the width direction along the vehicle.

[0038] S3: Determine whether the Y-direction width of the door sill guard meets the vehicle door sill PQ (Perceptual Quality) visualization requirements.

[0039] S4: If the Y-direction width of the sill guard does not meet the vehicle sill PQ visualization requirement, adjust the sill harness radius r until the Y-direction width of the sill guard meets the vehicle sill PQ visualization requirement. When the sill harness radius r is used for judgment, the maximum radius of the sill harness may be used first. The maximum radius of the sill harness may be input in advance based on the functional requirements of the vehicle.

[0040] In this embodiment, by fitting the main cross-section of the door sill, the Y-direction width of the door sill guard can be calculated based on the main cross-section of the door sill and the set door sill harness radius. By judging whether the Y-direction width of the door sill guard meets the vehicle door sill PQ visualization requirements, the door sill harness radius is gradually adjusted to achieve a balance between the door sill harness radius and the vehicle door sill PQ visualization as much as possible. The vehicle door sill PQ visualization requirements can be obtained through a large amount of benchmarking and subjective and objective research. In this embodiment of the application, the target value of the Y-direction width L of the door sill guard can be set to ≤120mm. That is, after calculating the Y-direction width of the door sill guard based on the main cross-section of the door sill and the set door sill harness radius, the Y-direction width of the door sill guard can be compared with the target value to judge whether the Y-direction width of the door sill guard 3 meets the target value. Figure 6 As shown, the door sill harness 2 can be arranged in the harness arrangement space, so there can be a certain ratio or specific size relationship between the door sill harness radius and the radius R of the harness arrangement space 4. Obtaining the door sill harness radius means obtaining the size of the radius R of the harness arrangement space 4, which solves the technical problems of visibility of the door sill guard plate 3 structure and difficulty in balancing the door sill harness arrangement space in the related art.

[0041] Furthermore, in one embodiment, fitting the rocker main section using a preset plane perpendicular to the vehicle's X-axis as a reference plane and the rocker stop 1 position as a reference point includes fitting the door and side panel structures, and supplementing the rocker internal and external component structures, using the preset plane perpendicular to the vehicle's X-axis as a reference plane and the rocker stop 1 position as a reference point to obtain the rocker main section. Specifically, the reference point and reference plane can be used to determine the specific location of the rocker main section within the body-in-white rocker to be fitted. The rocker structure within that section and other structures adjacent to the rocker periphery within the body-in-white are then integrated into the resulting rocker main section to enhance the structural integrity of the section. In this embodiment of the present application, the rocker stop 1 position can be a platform-like rocker stop 1 position.

[0042] In this embodiment, by setting clear reference planes and reference points, the fitting process of the main section of the threshold can be ensured to be more accurate, and the threshold structure and other structures around the threshold are focused on the threshold section structure, which can achieve more accurate size control and quality control in subsequent processing and calculation, solving the problem in related technologies that the threshold structure in the main section of the threshold has poor accuracy, affecting the accuracy of subsequent calculation results.

[0043] Furthermore, in one embodiment, the interior and exterior components of the threshold may include: a door interior panel, a threshold guard 3, a threshold inner panel 7, a wiring harness routing space 4, a threshold guard buckle 5, and a threshold welcome pedal structure 6. It can be understood that the door, side panel structure, and door interior panel are all structures surrounding the threshold structure. In addition, a carpet can also be fitted into the main section of the threshold. The threshold guard 3, threshold inner panel 7, wiring harness routing space 4, threshold guard buckle 5, and threshold welcome pedal structure 6 can all be structured as part of the threshold. The threshold structure and the threshold surrounding structures can be fitted into the main section of the threshold simultaneously, or the door and side panel structures can be fitted first, followed by the remaining structures.

[0044] This embodiment allows for the simultaneous or sequential fitting of various structures within the main section of the sill, resulting in greater flexibility and adaptability. By fitting the doors and side panels first, followed by the remaining structures, the remaining structures within the main section of the sill can use the doors and side panels as reference points, in addition to the sill stop 1. This improves the fitting speed and accuracy of the remaining structures, resolving the difficulty in controlling accuracy and speed in fitting the main section of the sill in related technologies.

[0045] Further, see Figure 2 As shown, in one embodiment, the calculation of the Y-axis width of the door sill guard based on the door sill main cross-section and the set door sill harness radius r may include:

[0046] S21: Based on the dimension chain relationship of each component in the main cross-section of the door sill, a calculation formula for the Y-axis width of the door sill guard is constructed. Here, each component may refer to multiple components in the door sill structure. In some other embodiments, a calculation formula for the Y-axis width of the door sill guard may also be constructed based on some components in the peripheral structure of the door sill structure.

[0047] S22: Calculate the radius R of the wiring harness arrangement space 4 based on the threshold wiring harness radius r, and substitute the radius R of the wiring harness arrangement space 4 into the calculation formula for the threshold guard's Y-direction width to obtain the threshold guard's Y-direction width. Before substituting the radius R of the wiring harness arrangement space 4 into the calculation formula for the threshold guard's Y-direction width, a dimensional relationship between the radius R of the wiring harness arrangement space 4 and the threshold wiring harness radius r can be first established. The threshold wiring harness radius r can then be calculated using the calculated radius R of the wiring harness arrangement space 4 based on this dimensional relationship. In the embodiment of the present application, the radius R of the wiring harness arrangement space 4 is 5 mm larger than the threshold wiring harness radius r, which is a constant value. Therefore, the value of the threshold wiring harness radius r can be obtained by calculating the radius R of the wiring harness arrangement space 4. Conversely, the radius R of the wiring harness arrangement space 4 can also be obtained by calculating the threshold wiring harness radius r.

[0048] In this embodiment, the positional relationships between multiple components within the sill structure allow for a relatively intuitive dimensional chain relationship within the component structure. This allows for a simple and clear formula to be used when constructing the Y-axis width calculation formula for the sill guard, facilitating subsequent calculations of the sill guard's Y-axis width using this formula. Furthermore, by establishing a relationship between the radius R of the wiring harness routing space 4 and the sill harness radius r, sufficient space for wiring harness routing within the sill is ensured, preventing harness compression or damage during assembly due to insufficient space. This addresses the prior art issue of the sill guard's Y-axis width being difficult to calculate using known information, leading to difficulty in balancing the sill guard's Y-axis width with the sill harness radius during the design process.

[0049] Further, see Figure 3 As shown, in one embodiment, the calculation formula for the Y-axis width of the door sill guard plate based on the dimension chain relationship of each component in the main cross-section of the door sill may include:

[0050] S211: Obtain a first distance L1 from the inner side of the sill panel structure 6 to the sill stop 1 along the Y direction, a second distance L2 from the inner side of the sill panel structure 6 to the center of the sill wiring harness 2 along the Y direction, and a third distance L3 from the sill guard buckle 5 along the Y direction. The center of the sill wiring harness 2 may refer to the center of the wiring harness arrangement space 4.

[0051] S212: Based on the dimensional chain relationship between the first distance L1, the second distance L2, the third distance L3, the radius R of the arrangement space and the Y-axis width of the door sill guard, a calculation formula for the Y-axis width of the door sill guard is constructed. Figure 5 and Figure 6 As shown, the Y-axis width of the door sill guard plate can be represented by L, and the dimensional chain relationship between the Y-axis width of the door sill guard plate and the components in the door sill main section can be: L=L1+L2+R+L3.

[0052] In this embodiment, by establishing a dimensional chain relationship between the Y-width of the threshold guard plate, the threshold with welcome pedal structure 6, the threshold guard plate buckle 5 and the threshold stop 1 structure, a calculation formula associated with each structure can be established, and the various components in the threshold structure are reasonably used. The above-mentioned components are directly related to the threshold guard plate 3, thereby simplifying the design of the calculation formula and the calculation process, and can also improve the accuracy of the calculation results and the degree of fit between each component and the threshold guard plate 3, thereby solving the problem in the related technology that the formula calculation process is complicated, the data conversion at this time excessively affects the accuracy of the calculation results, and affects the fit relationship between the various components.

[0053] Furthermore, in one embodiment, the second distance is calculated based on the Z-axis height H from the sill inner panel 7 to the sill with the welcome pedal structure 6, the draft angle θ of the sill inner panel 7, the sill harness radius r, and the first distance L1, see Figure 7 As shown, the data directly involved in the calculation of the second distance L2 are the Z-axis height H from the sill inner panel 7 to the sill with welcome pedal structure 6, the draft angle θ of the sill inner panel 7, the radius R of the wiring harness arrangement space 4 and the first distance L1.

[0054] Specifically, the calculation process of L2 can be done by Derivation, we get:

[0055]

[0056] In the embodiment of the present application, L1, L3, H, and θ are all fixed values. Once the platform threshold stop 1 is determined, H and θ are no longer adjusted or optimized. The L2 value is only related to the threshold harness radius r. The larger R is, the larger L2 is. There is a dimensional chain relationship between L2 and the Y-direction width of the threshold guard plate. In this case, the larger R is, the larger the Y-direction width of the threshold guard plate is.

[0057] In this embodiment, L2 is calculated by utilizing the draft angle of the rocker inner panel 7. During the design process, L1, L3, H, and θ can all be measured or calculated. By using directly obtainable numerical values ​​to establish a calculation formula for L2, the calculation convenience can be enhanced, solving the problem in related technologies of complex data, increased difficulty in calculation, and impact on the accuracy of calculation results.

[0058] Furthermore, in one embodiment, the preset plane is: a plane perpendicular to the vehicle X-axis and located a preset distance before the human body point R. Located before the human body point R can be understood as moving from the human body point R toward the front of the vehicle. The preset distance can be any value between 250-350 mm, and is set to 330 mm in the embodiment of the present application.

[0059] In this embodiment, by using a plane that is perpendicular to the vehicle X-axis and located a preset distance before the human body R point as a preset plane, the corners in the vehicle design can be effectively avoided to find a position in the rocker structure of the body-in-white where the space is as small as possible, or even the smallest position. In the subsequent design and calculation process, the cross-section at this position is used as the main cross-section of the rocker, which is more referenceable. That is, if the wire harness radius at the smaller space can meet the layout requirements of the rocker structure, then the rest of the larger space can also be met smoothly.

[0060] In a second aspect, an embodiment of the present application also provides a vehicle door sill section design device.

[0062] Furthermore, in one embodiment, the fitting module is used to fit the sill peripheral structure and the sill structure using a preset plane perpendicular to the vehicle X-axis as a reference plane and the position of the sill stop 1 as a reference point to obtain the main cross-section of the sill.

[0063] Furthermore, in one embodiment, the fitting module is also used to: fit the door, side structure, door interior panel, door sill guard plate 3, door sill inner panel 7, wiring harness layout space 4, door sill guard plate buckle 5 and door sill with welcome pedal structure 6 with the door sill stop 1 position as the reference point.

[0064] Furthermore, in one embodiment, the calculation module is used to: construct a calculation formula for the Y-direction width of the threshold guard based on the dimensional chain relationship of each component in the main section of the threshold; convert the threshold harness radius r into the radius R of the harness layout space 4 using the dimensional relationship, and substituted the radius R of the harness layout space 4 into the calculation formula to calculate the Y-direction width of the threshold guard.

[0065] Furthermore, in one embodiment, the calculation module is also used to: obtain the first distance L1 from the inner point of the threshold belt welcome pedal structure 6 to the threshold stop 1 along the Y direction, the second distance L2 from the inner point of the threshold belt welcome pedal structure 6 to the center of the threshold wiring harness 2 along the Y direction, and the third distance L3 of the threshold guard buckle 5 along the Y direction; based on the dimensional chain relationship between the first distance L1, the second distance L2, the third distance L3, the radius R of the layout space and the Y-direction width of the threshold guard, construct a calculation formula for the Y-direction width of the threshold guard.

[0066] Furthermore, in one embodiment, the calculation module is also used to: calculate the second distance based on the Z-axis height H from the sill inner panel 7 to the sill with welcome pedal structure 6, the draft angle θ of the sill inner panel 7, the sill harness radius r and the first distance L1.
