[0051] It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0052] In a first aspect, an embodiment of the present invention provides a method for designing an A-pillar section.

[0053] In one embodiment, referring to Figure 1 , Figure 1 FIG. 1 is a flow chart of an embodiment of the A-pillar cross-section design method of the present invention. Figure 1 As shown, the A-pillar section design method includes:

[0054] Step S10, determining the corresponding relationship between the A-pillar shielding angle and L, wherein L is the horizontal distance between the driver's eye point and point A, and point A is the tangent point between the driver's eye point and the window frame interior panel;

[0055] In this embodiment, different A-pillar arrangement plan sections have different A-point positions (i.e., the intersection point between the driver's eye point and the window frame interior panel), and different A-point positions will lead to different L values, so each A-pillar arrangement plan section has a corresponding L value. Each A-pillar arrangement plan section has a corresponding A-pillar shielding angle, so the corresponding relationship between the A-pillar shielding angle and L can be determined according to the A-pillar shielding angle corresponding to each A-pillar arrangement plan section and the L value.

[0056] Furthermore, in one embodiment, the step of determining the corresponding relationship between the A-pillar shielding angle and L includes:

[0057] The A-pillar shielding angles corresponding to multiple A-pillar arrangement scheme sections are calculated, wherein different A-pillar arrangement scheme sections have different L values; curve fitting is performed according to the A-pillar shielding angle and L value corresponding to each A-pillar arrangement scheme section to obtain a relationship curve between the A-pillar shielding angle and L.

[0058] In this embodiment, it is assumed that there are 10 A-pillar arrangement sections, and the L values ​​of the 10 A-pillar arrangement sections are 460mm, 480mm, 500mm, 520mm, 540mm, 560mm, 580mm, 600mm, 620mm and 640mm respectively. By calculating the A-pillar shielding angles corresponding to the 10 A-pillar arrangement sections, it is obtained that the A-pillar shielding angles corresponding to the 10 A-pillar arrangement sections are 13.4°, 12.8°, 12.3°, 11.8°, 11.4°, 10.9°, 10.5°, 10.1°, 9.8° and 9.4° respectively, then:

[0059] 460mm corresponds to 13.4°, 480mm corresponds to 12.8°, 500mm corresponds to 12.3°, 520mm corresponds to 11.8°, 540mm corresponds to 11.4°, 560mm corresponds to 10.9°, 580mm corresponds to 10.5°, 600mm corresponds to 10.1°, 620mm corresponds to 9.8°, 640mm corresponds to 9.4°. Based on the above correspondence, curve fitting can be performed to obtain the relationship curve between the A-pillar shielding angle and L. Figure 2 , Figure 2 Schematic diagram of the relationship between the A-pillar shielding angle and L in an embodiment of the A-pillar section design method of the present invention.

[0060] It is easy to understand that in addition to determining the correspondence between the A-pillar occlusion angle and L by constructing a relationship curve between the A-pillar occlusion angle and L, the correspondence between the A-pillar occlusion angle and L can also be determined by interpolation based on the known A-pillar occlusion angle and the corresponding L value.

[0061] Furthermore, in one embodiment, the step of calculating the A-pillar shielding angles corresponding to the sections of the multiple A-pillar arrangement solutions includes:

[0062] Substitute the L value of each A-pillar layout section into the A-pillar shielding angle calculation formula to obtain the A-pillar shielding angle corresponding to each A-pillar layout section. The A-pillar shielding angle calculation formula is:

[0063]

[0064] Among them, H1, H2 and a are preset values, and α is the A-pillar blocking angle.

[0065] In this embodiment, refer to Figure 3 , Figure 3 Schematic diagram of the geometric relationship of the A-pillar shielding angle in the first embodiment of the A-pillar cross-section design method of the present invention. Figure 3 As shown, point P is the eye point 635mm above the driver's point R. The driver's point R is the seat reference point, a hip point on a specified seat position. There is only one seat reference point for each seat. Point A is the tangent point between point P and the window frame interior panel, and point B is the innermost point of the black edge of the front windshield.

[0066] After determining an A-pillar layout plan section, extract the outer contour line of the A-pillar interior panel and the black edge line of the front windshield in the A-pillar layout plan section as the contour, and use the D-line line in the A-pillar CAS surface as the guide curve. Use the sweep command to sweep out the initial 3D data of the window frame decorative panel and the black edge of the front windshield. Through the initial 3D data combined with the position of point P, the plane passing through point P and parallel to the horizontal plane intersects with the initial 3D data to determine the position of point A and point B. At this point, the following can be obtained: Figure 3 The geometric relationship diagram of the A-pillar shielding angle is shown in FIG. Combined with this diagram, we have:

[0067]

[0068] Among them, since the values ​​of H1, H2 and a are fixed in the design of a certain vehicle model, H1 is the longitudinal distance between point P and point A, H2 is the longitudinal distance between point P and point B, and a is the lateral width of the window frame (related to the standard section of the window frame, and the value of a is a fixed value after the section of the window frame of different vehicle models is determined), it is only necessary to know the value of L to calculate the corresponding A-pillar shielding angle.

[0069] Step S20, determining a target L value according to the corresponding relationship and an ideal range of the A-pillar shielding angle;

[0070] In this embodiment, the ideal range of the A-pillar shielding angle is pre-set according to actual needs, and is specifically set according to the driver's field of vision requirements. For example, the ideal range of the A-pillar shielding angle is less than or equal to 11°. On this basis, combined with the corresponding relationship between the A-pillar shielding angle and L determined in step S10, the value range of the L value when the A-pillar shielding angle is less than or equal to 11° can be determined, so as to select the target L value from the value range of the L value.

[0071] The corresponding relationship between the A-pillar shielding angle and L is as follows Figure 2 As shown, when the ideal range of the A-pillar shielding angle is less than or equal to 11°, the range of the L value is greater than or equal to 558 mm, and the target L value can be selected from the range greater than or equal to 558 mm.

[0072] Step S30, constructing a section of the A-pillar arrangement scheme to be verified corresponding to the target L value;

[0073] In this embodiment, when the target L value can be selected from the range greater than or equal to 558 mm, the target L value selected for the first time can be 558 mm, and then the A-pillar arrangement solution section to be checked with an L value of 558 mm is constructed. For example, a basic model consisting of the front windshield glass surface, the side window glass and the A-pillar CAS surface is first constructed, and then the window frame standard section, the front windshield standard section, the window frame interior panel, the wiring harness, the drain pipe, the side air curtain and other contents are fitted to the basic model, and when fitting, the horizontal distance between the driver's eye point and point A needs to be equal to 558 mm, and point A is the tangent point between the driver's eye point and the window frame interior panel, so as to obtain the A-pillar arrangement solution section to be checked corresponding to 558 mm.

[0074] Step S40, detecting whether the cross section of the A-pillar arrangement scheme to be checked meets the offset collision requirement;

[0075] In this embodiment, it is determined in advance which indicators of the A-pillar arrangement section the offset collision requirement has requirements on and what the requirements are, so as to set the parameters to be obtained and the judgment conditions.

[0076] After the A-pillar arrangement scheme section to be checked corresponding to the target L value is constructed, relevant parameters are obtained from the A-pillar arrangement scheme section to be checked according to the set parameters to be obtained and the judgment conditions, and then it is determined whether the A-pillar arrangement scheme section to be checked meets the offset collision requirements based on the obtained relevant parameters and the judgment conditions.

[0077] Furthermore, in one embodiment, step S40 includes:

[0078] Obtaining the effective cavity area of ​​the A-pillar side enclosure in the section of the A-pillar arrangement scheme to be checked; detecting whether the effective cavity area of ​​the A-pillar side enclosure is within a preset area range; if it is within the preset area range, determining that the section of the A-pillar arrangement scheme to be checked meets the offset collision requirement.

[0079] In this embodiment, the A-pillar of the car plays a role in transferring energy backwards during a collision. As collision regulations become stricter, higher requirements are placed on the cavity space of the A-pillar. Generally speaking, the larger the effective cavity space of the A-pillar side (the cavity area enclosed by the A-pillar reinforcement plate and the inner plate), the better the energy absorption effect in an offset collision, which can effectively improve the safety performance of the vehicle in a collision. Therefore, the preset area range is set according to the provisions of the effective cavity area of ​​the A-pillar side according to the offset collision requirements.

[0080] The area enclosed by the A-pillar reinforcement plate and the inner panel is extracted from the cross-section of the A-pillar arrangement scheme to be checked, and the area of ​​the area is read to obtain the effective cavity area of ​​the A-pillar side panel; then, it is detected whether the effective cavity area of ​​the A-pillar side panel is within a preset area range; if it is within the preset area range, it is determined that the cross-section of the A-pillar arrangement scheme to be checked meets the offset collision requirement; on the contrary, if the effective cavity area of ​​the A-pillar side panel is not within the preset area range, it is determined that the cross-section of the A-pillar arrangement scheme to be checked does not meet the offset collision requirement.

[0081] Step S50: If the conditions are met, it is determined that the A-pillar arrangement section to be checked is valid.

[0082] In this embodiment, based on steps S10 to S30, the cross-section of the A-pillar arrangement scheme to be checked meets the driver's field of vision requirements. If it is detected through step S40 that the cross-section of the A-pillar arrangement scheme to be checked meets the offset collision requirements, it means that the currently constructed cross-section of the A-pillar arrangement scheme to be checked takes into account both the driver's field of vision requirements and the safety collision requirements, and the cross-section of the A-pillar arrangement scheme to be checked is determined to be valid.

[0083] Furthermore, when it is determined that the section of the A-pillar arrangement scheme to be checked is valid, it can be automatically stored, for example, in a non-volatile memory. Moreover, after this, a new target L value can also be determined. For example, when the target L value can be selected from a range greater than or equal to 558mm, the first selected target L value is 558mm. When the target L value is 558mm, if it is determined that the section of the A-pillar arrangement scheme to be checked corresponding to the target L value is valid, 559mm is selected as the new target L value, and then the section of the A-pillar arrangement scheme to be checked corresponding to 559mm is constructed, and it is determined whether the section of the A-pillar arrangement scheme to be checked corresponding to 559mm is valid, and when it is detected to be valid, it is stored in a non-volatile memory, and so on. In this way, a variety of A-pillar arrangement scheme sections that take into account the driver's field of vision requirements and safety collision requirements can be stored in a non-volatile memory for further manual selection.

[0084] In this embodiment, the correspondence between the A-pillar shielding angle and L is determined, wherein L is the lateral distance between the driver's eye point and point A, and point A is the tangent point between the driver's eye point and the window frame interior panel; the target L value is determined according to the correspondence and the ideal range of the A-pillar shielding angle; the section of the A-pillar arrangement scheme to be checked corresponding to the target L value is constructed; it is detected whether the section of the A-pillar arrangement scheme to be checked meets the offset collision requirement; if it does, it is determined that the section of the A-pillar arrangement scheme to be checked is valid. Through this embodiment, the target L value of the A-pillar field of view that meets the driver's needs can be automatically selected according to the correspondence between the A-pillar shielding angle and L, and then the section of the A-pillar arrangement scheme to be checked corresponding to the target L value can be checked to see whether it meets the offset collision requirement. Only when the A-pillar field of view meets the driver's needs and meets the offset collision requirement, the section of the A-pillar arrangement scheme to be checked is considered valid, and there is no need to manually adjust the section of the A-pillar arrangement scheme repeatedly according to experience, thereby improving the design efficiency of the section of the A-pillar arrangement scheme.

[0085] Furthermore, in one embodiment, after step S40, the method further includes:

[0086] If it is not within the preset area range, return to step S20.

[0087] In this embodiment, if the effective cavity area of ​​the A-pillar side is not within the preset area range, it is determined that the A-pillar arrangement plan section to be checked only meets the driver's field of vision requirements but does not meet the offset collision requirements, so the process returns to step S20, that is, reselecting a target L value that has not been selected before from the L value range, and then constructing the A-pillar arrangement plan section to be checked and detecting whether the effective cavity area of ​​the A-pillar side in the A-pillar arrangement plan section to be checked is within the preset area range. It is easy to understand that if it is within the preset area range, the process proceeds to step S50, and if it is not within the preset area range, the process returns to step S20.

[0098] Furthermore, in one embodiment, the relationship determination module 10 is used to:

[0099] Substitute the L value of each A-pillar layout section into the A-pillar shielding angle calculation formula to obtain the A-pillar shielding angle corresponding to each A-pillar layout section. The A-pillar shielding angle calculation formula is:

[0100]

[0101] Among them, H1, H2 and a are preset values, and α is the A-pillar blocking angle.
