Description

Technical Field

[0001] This invention relates to the field of vehicle design technology, and more specifically, to a method, device, and medium for determining the position of the rotating shaft of the charging port cover of a new energy vehicle. Background Technology

[0002] The current charging port cover rotation axis of new energy vehicles is mostly arranged and positioned based on experience. In the early stage of product design, the actual working conditions of the charging port cover and the environmental conditions of the whole vehicle were not systematically considered. There is a lack of standardized parameter control, stroke clearance control and environmental safety space avoidance process. Furthermore, the complete three-dimensional model of the charging port cover component and various geometric data were not used for accurate deduction. This can easily lead to unreasonable placement of the center position of the rotation axis, which may cause hidden dangers in the operation of the mechanism in subsequent real vehicle use.

[0003] There is currently no effective solution to the above problems. Summary of the Invention

[0035] Figure 1 This is a flowchart illustrating a method for determining the position of the rotating shaft of a charging port cover for a new energy vehicle according to one embodiment of the present invention. Figure 1 As shown, the method includes the following steps:

[0036] Step S110: Obtain the 3D model and geometric data of the charging port cover assembly for the new energy vehicle. The specific details are as follows:

[0037] In step S110, the three-dimensional model and geometric data of the charging port cover assembly of the new energy vehicle are first obtained, such as... Figure 2 and Figure 3As shown, the charging port cover assembly for new energy vehicles includes: a charging port cover assembly, a fixing reinforcement plate, and a decorative panel. The arrangement of these three components is as follows: the fixing reinforcement plate is first fixed to the decorative panel from the inside out using assembly methods such as screwing, snap-fitting, or welding; then, the charging port cover assembly is fixed to the fixing reinforcement plate from the inside out using standard parts. The charging port cover assembly includes: an outer charging port cover plate, a hinge arm, a bushing, damping, a spring, a rotating shaft, a base, and a lock body. Geometric data includes at least: the thickness data of each component in the charging port cover assembly for new energy vehicles, the gap data between each component in the charging port cover assembly for new energy vehicles, the radius of the rotating shaft, and the width of the hinge arm.

[0038] Step S120: Based on the 3D model and the geometric data, determine the center point data of the rotation axis through the longitudinal plane of the vehicle center. The specific details are as follows:

[0039] In step S120, the intersection line data between the vehicle's center longitudinal plane and the first styling surface of the decorative panel, and the intersection line data between the vehicle's center longitudinal plane and the second styling surface of the charging port cover are first determined based on the 3D model and the vehicle's center longitudinal plane, as follows:

[0040] like Figure 4 As shown, the longitudinal plane S of the vehicle center is the longitudinal plane of the charging port cover Y0 center. The shaped surfaces of the decorative panel and the outer panel of the charging port cover are simultaneously cut by the longitudinal plane S of the vehicle center, forming the intersection line data L1 of the first shaped surface of the decorative panel and the intersection line data L2 of the second shaped surface of the charging port cover. The first shaped surface intersection line data L1 is a preset rotation axis arranged inside, and the second shaped surface intersection line data L2 of the vehicle center longitudinal plane and the outer panel of the charging port cover is an inwardly folded edge that can be drawn at both ends.

[0041] like Figure 5 As shown, based on the thickness data, gap data, and rotation axis radius in the geometric data, the in-vehicle offset distance D1 is determined as follows:

[0042] The offset distance D1 inside the vehicle is determined as shown in formula (1):

[0043] D1=t1+d1+t2+d2+t3+d3+t4+r1(1);

[0044] Wherein, t1 is the thickness of the decorative panel (2.5mm-3.5mm for plastic parts; 0.65mm-0.7mm for sheet metal outer coverings), d1 is the distance between the decorative panel and the fixed reinforcing plate (usually 1mm, 0.5mm for welding; 2mm for snap-fit), t2 is the thickness of the fixed reinforcing plate (2.5mm-3.5mm for plastic parts, 0.7mm-1.4mm for sheet metal reinforcing plates, the thickness should be selected according to the body strength and safety structure requirements), d2 is the gap between the fixed reinforcing plate and the base (≥2mm), t3 is the thickness of the base 10 (3mm-4mm), d3 is the gap between the hinge arm and the base 10 (≥2mm), t4 is the damping thickness (according to standard part specifications), and r1 is the radius of the rotation axis (4mm-6mm, integer values ​​are recommended). The above parameters are based on actual technical requirements and can be preset according to the provided reference values, and adjusted within the parameter setting range based on the subsequent CAE computer simulation calculation results. The dashed lines in each diagram represent the pre-defined components that illustrate the composition of the parts.

[0045] Based on the in-vehicle offset distance D1 and the first styling surface intersection line data L1, the initial trajectory data L3 of the rotation axis center is determined by offsetting the first styling surface intersection line data L1 in-vehicle distance D1.

[0046] like Figure 6 As shown, based on the thickness data, gap data, and hinge arm width in the geometric data, the lower offset distance D2 is determined as follows:

[0047] The lower offset distance D2 is determined as shown in formula (2):

[0048] D2=t1+d1+t2+d2+t3+d3+t5(2);

[0049] Where: t5 is 0.5 times the Z width of the hinge arm, and the Z width of the hinge arm is usually ≥15mm.

[0050] Based on the lower offset distance D2 and the initial trajectory data L3 of the rotation axis center, the position data of the upper boundary curve is determined as follows: the upper flange surface of the decorative panel 3 is offset downward by a distance D2 to form curve L4; the intersection point of curve L4 and the initial trajectory data L3 of the rotation axis center is P1. P1 is the upper boundary of the initial trajectory data L3 of the rotation axis center, and P1 is the position data of the upper boundary curve.

[0051] like Figure 7 As shown, based on the initial trajectory data L3 of the rotation axis center, the initial position of the first center of the first auxiliary circle C1 is determined, that is, the initial position of the first center of the first auxiliary circle C1 is on the initial trajectory data L3 of the rotation axis center.

[0052] Based on the intersection line data of the second shape surface, the first initial boundary position of the first auxiliary circle is determined, that is, the first auxiliary circle C1 is tangent to the flange of the outer plate of the charging port cover;

[0053] like Figure 8 As shown, based on the preset safety distance, the initial position of the first center, and the first initial boundary position, the first final center position of the first auxiliary circle C1 is determined, wherein the preset safety distance is the distance D3 between the first initial boundary position and the outer fillet of the decorative panel, which is greater than or equal to 1.5mm.

[0054] like Figure 9 As shown, based on the first final center position, the lower boundary curve position data L4 is determined. The specific steps are as follows: The center P2 of the first auxiliary circle C1 is the lower boundary of the initial trajectory data L3 of the rotation axis center. The portion of the initial trajectory data L3 of the rotation axis center at points P1 and P2 is the rotation axis boundary position data L4. The axis trajectory of the charging port cover's rotation axis must be set on the rotation axis boundary position data L4 to ensure smooth and reliable operation of the charging port cover during opening and closing.

[0055] like Figure 10 As shown, based on the rotation axis boundary position data L4, the initial position of the second center of the second auxiliary circle C2 is determined. Based on the initial position of the second center, the second initial boundary position of the second auxiliary circle C2 is determined by the preset decorative panel flange distance, wherein the flange distance D4 between the second auxiliary circle C2 and the decorative panel (3) is 3mm. Based on the preset environmental data gap data, hinge arm width, initial position of the second center and second initial boundary position, the second final center position of the second auxiliary circle is determined, wherein the preset environmental data gap data D5 ≥ hinge arm bend thickness + 5mm, and the hinge arm bend thickness is 5mm-10mm.

[0056] Based on the second final center position, the rotation axis center point data is determined. The distance between the second final center position and the lower boundary curve position data is greater than the distance between the second final center position and the upper boundary curve position data. The center point P3 of the second auxiliary circle C2 is as close as possible to the lower boundary of the rotation axis boundary position data L4, and the center point P3 of the second auxiliary circle C2 is as close as possible to the center P2 of the first auxiliary circle C1. Center point P3 is the center point of the rotation axis.

[0057] Step S140: Based on the center point data of the rotation axis and the radius of the rotation axis, determine the target structure of the rotation axis of the charging port cover of the new energy vehicle.

[0058] like Figure 11 As shown, in step S140, the center point P3 is stretched along the Y direction to both sides to form a straight line L5, and the straight line L5 is symmetrical about the longitudinal plane S of the vehicle center; the length Len of the straight line L5 is greater than or equal to 0.4 times the length of the outer panel of the charging port cover in the same direction. With the straight line L5 as the center line of the rotation axis and the r1 value set in the geometric data as the radius of the rotation axis, the rotation axis of the charging port cover is formed.

[0059] Based on steps S110 to S140 above, in this embodiment of the invention, by acquiring the three-dimensional model and various geometric data of the charging port cover assembly, accurately determining the center point data of the rotation axis based on the longitudinal plane of the vehicle center, and combining the radius of the rotation axis to complete the determination of the target structure, the rotation axis is scientifically and standardizedly arranged in the early stage of design, effectively optimizing the adaptability and operational reliability of the charging port cover motion mechanism, avoiding potential functional failures during actual vehicle use, and improving the overall design accuracy and product quality of the charging port cover. This solves the technical problem in the prior art where the rotation axis of the charging port cover of traditional new energy vehicles relies on experience for layout and positioning, lacks a standardized process, and is prone to poor mechanism coordination and functional failures in the later stage.

[0060] The method for determining the rotation axis position of the charging port cover in a new energy vehicle according to an embodiment of the present invention, based on a three-dimensional model and geometric data, determines the center point data of the rotation axis through the longitudinal plane of the vehicle center. This includes: determining the intersection line data between the longitudinal plane of the vehicle center and a first styling surface of the decorative panel, and the intersection line data between the longitudinal plane of the vehicle center and a second styling surface of the charging port cover outer panel, based on the three-dimensional model and the longitudinal plane of the vehicle center; and determining the center point data of the rotation axis based on the intersection line data of the first and second styling surfaces and the geometric data. By accurately obtaining the intersection line using the three-dimensional model and geometric data, the position of the center point of the charging port cover's rotation axis can be determined efficiently and accurately.

[0061] Furthermore, based on the intersection line data of the first and second styling surfaces and geometric data, the center point data of the rotation axis is determined, including: determining the in-vehicle offset distance based on the thickness data, gap data, and rotation axis radius in the geometric data; determining the initial trajectory data of the rotation axis center based on the in-vehicle offset distance and the intersection line data of the first styling surface; and determining the center point data of the rotation axis based on the initial trajectory data of the rotation axis center, the intersection line data of the second styling surface, and the thickness data, gap data, and hinge arm width in the geometric data. By combining multiple geometric parameters and calculating step by step, the position of the center point of the charging port cover's rotation axis can be accurately and compliantly determined, meeting the assembly and structural design requirements.

[0062] Furthermore, based on the initial trajectory data of the rotation axis center, the intersection line data of the second shaping surface, and the thickness, gap, and hinge arm width in the geometric data, the rotation axis center point data is determined. This includes: based on the initial trajectory data of the rotation axis center, the intersection line data of the second shaping surface, the hinge arm width, and the thickness and gap data in the geometric data, the rotation axis boundary position data is determined by a preset safety distance. The rotation axis boundary position data includes the upper boundary curve position data and the lower boundary curve position data. Based on the rotation axis boundary position data and the hinge arm width, the rotation axis center point data is determined by a preset environmental gap data. By relying on multi-dimensional data combined with safety distances and environmental gaps to define boundaries, the rotation axis center point is accurately located, adapting to actual assembly and usage conditions.

[0063] Furthermore, based on the initial trajectory data of the rotation axis center, the intersection line data of the second shaping surface, the hinge arm width, and the thickness and gap data in the geometric data, the boundary position data of the rotation axis is determined by a preset safety distance. This includes: determining the lower offset distance based on the thickness, gap, and hinge arm width in the geometric data; determining the upper boundary curve position data based on the lower offset distance and the initial trajectory data of the rotation axis center; and determining the lower boundary curve position data based on the initial trajectory data of the rotation axis center, the intersection line data of the second shaping surface, and the preset safety distance. By using various structural parameters and safety distances to define the upper and lower boundaries, the layout range of the rotation axis can be standardized, ensuring the safe and reasonable assembly of the structure.

[0064] Furthermore, based on the initial trajectory data of the rotation axis center, the intersection line data of the second shaping surface, and the preset safety distance, the position data of the lower boundary curve is determined, including: determining the initial position of the first center of the first auxiliary circle based on the initial trajectory data of the rotation axis center; determining the first initial boundary position of the first auxiliary circle based on the intersection line data of the second shaping surface; determining the first final center position of the first auxiliary circle based on the preset safety distance, the initial center position, and the first initial boundary position; and determining the position data of the lower boundary curve based on the first final center position. By combining auxiliary circle positioning with safety distance correction, the position of the lower boundary curve of the rotation axis is accurately and quickly obtained, with high positioning accuracy and conformity to design standards.

[0065] Furthermore, based on the rotation axis boundary position data and hinge arm width, and through preset environmental data gap data, the rotation axis center point data is determined, including: determining the initial position of the second center of the second auxiliary circle based on the rotation axis boundary position data; determining the second initial boundary position of the second auxiliary circle based on the initial position of the second center and through a preset decorative panel flange distance; determining the second final center position of the second auxiliary circle based on the preset environmental data gap data, hinge arm width, initial position of the second center, and second initial boundary position; and determining the rotation axis center point data based on the second final center position, accurately determining the rotation axis center coordinates to meet the vehicle assembly space and structural layout requirements.

[0066] Furthermore, the distance between the second final center position and the lower boundary curve position data is greater than the distance between the second final center position and the upper boundary curve position data, making the rotation axis center placement position more in line with the actual opening and closing motion space requirements.

[0067] Through the above description of the embodiments, those skilled in the art can clearly understand that the methods according to the above embodiments can be implemented by means of software plus necessary general-purpose hardware platforms.
