AI Technical Summary
In existing technologies, the joint models built using SFE-Concept software lack universality, resulting in inconsistent coding numbers for joint connection sections and beam connection sections when importing different parametric models of vehicle body concepts. This leads to confusion in the connection surfaces, a large workload for adjustment and modification, and affects the efficiency of vehicle body model building.
A modular joint construction method is adopted, with transition sections set at both ends of the joint. The connection surface is adjusted by manually patching the surface to ensure parameter isolation between the joint and the beam. Only the transition section needs to be adjusted to adapt to different body models, thus achieving the universality of the modular joint.
It improves the efficiency of creating vehicle body models in SFE-Concept software, reduces the time required to adjust or rebuild joint models, and enables the reuse of joints and parameter unification in different vehicle body models.

Abstract
Description
Technical Field
[0001] This application belongs to the field of SFE-Concept software technology, specifically relating to a method for constructing a modular connector based on SFE-Concept software and the modular connector itself. Background Technology
[0002] A parametric model of the vehicle body concept was built using SFE-Concept software. This model contains conceptual geometric data, allowing for rapid mesh generation and enabling performance analysis at the concept vehicle stage. Modeling work using SFE-Concept software primarily focused on the geometric modeling of beams and joints, as well as attribute definition and map connections. In geometric modeling, the modeling time for a single ordinary joint is approximately four hours, roughly ten times the modeling time for a single beam. For example, a vehicle body model has nine joints, meaning the modeling time for the joints alone amounted to 36 hours, directly impacting the overall vehicle body assembly efficiency.
[0003] In current joint modeling, the general approach follows a holistic modeling strategy: the internal structure and both ends of the joint are built, and identical AGR groups are defined for structurally similar areas. Faces are automatically generated, ensuring a clean connection between the joint ends and the beam. However, joints built using this method lack universality, making them unusable. When importing other vehicle body concept parametric models, the coding numbers for the joint and beam cross-sections cannot be guaranteed to be consistent. This may be due to structural differences or inconsistent modeling practices, leading to chaotic joint model connections and misaligned internal automatic connection surfaces. The workload for adjustment and modification is essentially equivalent to rebuilding the joint entirely. Summary of the Invention
[0004] This application aims to at least partially address the technical problem that the joint models currently built using SFE-Concept software lack universality. To this end, this application provides a method for constructing modular joints based on SFE-Concept software, as well as the modular joint itself.
[0005] The technical solution of this application is as follows:
[0006] On the one hand, this application provides a method for constructing modular connectors based on SFE-Concept software, the method comprising:
[0007] A model of the joint is created using SFE-Concept software, and the end faces of both ends of the joint are the joint connection sections.
[0008] The SFE-Concept software is used to construct transition sections at both ends of the joint. The portion between the joint connection section and the transition section at each end of the joint is the transition section, and the portion between the transition sections at both ends of the joint is the main body.
[0009] The connection surface within the transition section is adjusted using the manual surface patching mode of the SFE-Concept software, based on the beam connection cross-section of the beam used to connect with the joint.
[0010] Furthermore, the length of the transition portion is 40mm to 60mm.
[0011] Furthermore, the joint connection section at each end of the joint is parallel to the transition section.
[0012] Furthermore, transition sections are constructed at both ends of the joint using the SFE-Concept software, including:
[0013] Copy the joint connection section, define the copied joint connection section as the transition section, then set the transition section on the joint, and adjust the size of the transition section according to the principle of smooth structural transition.
[0014] Furthermore, the copying of the joint connection section defines the copied joint connection section as the transition section, and then the transition section is set on the joint. The dimensions of the transition section are then adjusted according to the principle of smooth structural transition, including:
[0015] The joint connection section can be quickly located using the Local Section of the SFE-Concept software. Click the Modify option of the SFE-Concept software to enter the Modify Base Section interface of the Modify option, copy the joint connection section and save it as the transition section.
[0016] Using the JOINT module of the SFE-Concept software, the transition section is added to the joint, and then the specific position of the transition section on the joint is adjusted.
[0017] The transition section can be quickly located using the INFO option in the JOINT section. Based on the principle of smooth structural transition, the size of the joint connection section can be adjusted using the coordinates of the Node points in the Modify Base Section interface.
[0018] Furthermore, adjusting the connecting surfaces within the transition section using the manual surface patching mode of the SFE-Concept software includes:
[0019] Establish connecting lines between corresponding points on the joint connection section and the transition section to form a closed frame. Then select and confirm the closed frame to generate a filled surface.
[0020] Furthermore, the step of establishing connecting lines between corresponding points on the joint connection section and the transition section to form a closed frame, and then selecting and confirming the closed frame to generate a filled surface, includes:
[0021] Using the JOINT module of the SFE-Concept software, and employing the Create / ModifyLines function of the JOINT module, a connection line is created between the corresponding points of the joint connection section and the transition section.
[0022] Using the Single Surface function of the JOINT module, locate the joint, then select all the boundary lines of the closed frame, and after confirmation, the fill surface is generated.
[0023] Furthermore, the method also includes:
[0024] Before constructing the surfaces within the transition section using the manual surface patching mode of the SFE-Concept software, the dimensions of the main body are adjusted using the SFE-Concept software so that the dimensions of the joint and the beam are in the same proportion.
[0025] Furthermore, adjusting the size of the main body using the SFE-Concept software includes:
[0026] The transition section can be quickly located using the Local Section of the SFE-Concept software. Clicking the Modify option in the SFE-Concept software will take you to the Modify Base Section interface. By adjusting the coordinates of the Node points in the Modify Base Section interface, the size of the transition section can be automatically updated.
[0027] On the other hand, this application also provides a modular connector, characterized in that the connector is constructed by the above-described modular connector construction method based on SFE-Concept software.
[0028] The embodiments of this application have at least the following beneficial effects:
[0029] This application provides a method for constructing modular joints based on SFE-Concept software. By setting transition sections at both ends of the joint, the transition sections are kept parametrically isolated from the main body of the joint. Thus, when importing different parametric models of vehicle body concepts into SFE-Concept software, only the transition sections of the joint need to be modified and adjusted. The time required to adjust the transition sections is much less than the time required to adjust the joint itself or rebuild the joint model. This enables the construction of universal modular joints in SFE-Concept software and improves the efficiency of building vehicle body models in SFE-Concept software. Attached Figure Description

[0037] This application is described below with reference to the accompanying drawings and specific embodiments:
[0038] Please refer to Figure 1 as well as Figure 2 This application proposes a method for constructing modular connectors based on SFE-Concept software, combined with... Figure 1 as well as Figure 2 The method includes the following steps:
[0039] S1: A model of connector 100 is created using SFE-Concept software. The end faces of both ends of connector 100 are the connector connection sections 130.
[0040] Based on the relevant parameters of joint 100, a model of joint 100 is built in the SFE-Concept software. The joint connection sections 130 at both ends of joint 100 are used to connect with the beam connection sections of beams. The joint connection sections 130 of joint 100 and the beam connection sections of beams are the same section, thus connecting different beams together through joint 100. However, importing different parametric models of the vehicle body concept into the SFE-Concept software will cause the coding numbers of the joint connection sections 130 of joint 100 and the beam connection sections of beams to be inconsistent. As a result, after joint 100 is connected to the beam, the connection surfaces inside joint 100 become chaotic. If joint 100 is modified and adjusted, the time required is no less than rebuilding a model of joint 100 in the SFE-Concept software. Therefore, the model of joint 100 built in the SFE-Concept software at this time is not universal.
[0041] S2: Using SFE-Concept software, transition sections 140 are constructed at both ends of the connector 100. The part between the connector connection section 130 and the transition section 140 at each end of the connector 100 is the transition part 120, and the part between the transition parts 120 at both ends of the connector 100 is the main body 110.
[0042] Using SFE-Concept software, transition sections 140 are constructed at both ends of the connector 100 to separate the two ends of the connector 100. The parameters between the main body 110 and the transition portion 120 of the connector 100 do not affect each other, so that parameter isolation is achieved between the main body 110 and the transition portion 120 of the connector 100. The connection between the main body 110 and the transition portion 120 of the connector 100 is achieved through the transition section 140.
[0043] S3: Adjust the connection surface within the transition section 120 using the manual surface patching mode of the SFE-Concept software, based on the beam connection section of the beam used to connect with the joint 100.
[0044] In the SFE-Concept software, the connector 100, whose joint connection section 130 has a different code number than the beam connection section code number, is connected to the beam. The joint connection section 130 of the connector 100 and the beam connection section are the same section. To avoid adjusting or rebuilding the model of the connector 100, only the transition section 120 needs adjustment. Based on the joint connection section 130 (beam connection section) on the transition section 120, the connections within the entire transition section 120 are adjusted accordingly. The joint surface is used to connect the joint connection section 130 of the transition section 120 to the connection surface 140 of the transition surface. The adjustment of the transition section 120 requires the manual surface patching mode of the SFE-Concept software to ensure that the transition section 120 of the joint 100 and the main body 110 of the joint 100 always maintain parameter isolation. If the automatic connection mode of the SFE-Concept software is used, it is not possible to ensure that the transition section 120 of the joint 100 and the main body 110 of the joint 100 maintain parameter isolation.
[0045] In summary, by setting transition portions 120 at both ends of the connector 100, parameter isolation is maintained between the transition portions 120 and the main body 110 of the connector 100. Thus, when importing different parametric models of the vehicle body concept into the SFE-Concept software, only the transition portions 120 of the connector 100 need to be modified. The time required to adjust the transition portions 120 of the connector 100 is much less than the time required to adjust the connector 100 or rebuild the model of the connector 100. This enables the construction of a universal modular connector in the SFE-Concept software and improves the efficiency of building vehicle body models in the SFE-Concept software.
[0046] In this embodiment, the length of the transition portion 120 of the connector 100 is 40mm to 60mm, that is, the distance between the connector connection section 130 and the transition section 140 of the transition portion 120 of each connector 100 is 40mm to 60mm, so as to ensure a smooth transition connection of the transition portion 120 of the connector 100 and the adjustment time of the transition portion 120 of the connector 100. If the length of the transition portion 120 of the connector 100 is too short, a smooth transition connection of the transition portion 120 of the connector 100 cannot be guaranteed; if the length of the transition portion 120 of the connector 100 is too long, the adjustment time of the transition portion 120 of the connector 100 will be too long.
[0047] In this embodiment of the application, the connector connection section 130 at each end of the connector 100 is parallel to the transition section 140, so as to facilitate operation in the SFE-Concept software.
[0048] In this embodiment of the application, the construction of the transition section 140 in step S2 includes copying the connector connection section 130. The copying connector connection section 130 is defined as the transition section 140. Then, the size of the transition section 140 is adjusted according to the principle of smooth structural transition. The transition section 140 is then set on the connector 100 to realize the setting of the transition section 140 and make the size of the transition section 140 consistent with that of the connector 100.
[0049] Specifically, in the SFE-Concept software, the connector connection section 130 is quickly located using the Local Section module. Then, the Modify option in the SFE-Concept software is clicked to enter the ModifyBase Section interface. The connector connection section 130 is copied and saved as a transition section 140. Using the JOINT module in the SFE-Concept software, the transition section 140 is added to the connector 100. The specific position of the transition section 140 on the connector 100 is then adjusted. The transition section 140 is quickly located using the INFO option in the JOINT module. Based on the principle of smooth structural transition, the dimensions of the connector connection section 130 are adjusted using the coordinates of the Node points in the Modify Base Section interface.
[0050] In this embodiment of the application, the manual surface patching mode of step S3 includes establishing a connecting line between corresponding points on the joint connection section 130 and the transition section 140 to form a closed frame, and then selecting and confirming the closed frame to generate a fill surface, thereby modifying and adjusting the transition section 120 through the manual surface patching mode.
[0051] Specifically, in the SFE-Concept software, the JOINT module is used to create connection lines between corresponding points on the joint connection section 130 and the transition section 140 using the Create / Modify Lines function. The Single Surface function of the JOINT module is used to locate the joint 100, and then all boundary lines of the closed frame are selected. After confirmation, the fill surface is generated.
[0052] In this embodiment of the application, the method for constructing a modular joint based on SFE-Concept software further includes adjusting the size of the joint 100 using SFE-Concept software between steps S2 and S3, so that the size ratio of the joint 100 to the beam is the same. Since the size ratio of some beams may not match that of the joint 100, the joint 100 and the beam will not match in size after connection.
[0053] Specifically, in the SFE-Concept software, the transition section 140 can be quickly located through the Local Section section. Clicking the Modify option in the SFE-Concept software will take you to the ModifyBase Section interface. By adjusting the coordinates of the Node points in the Modify Base Section interface, the size of the transition section 140 will be automatically updated.
[0054] Of course, the SFE-Concept software can also rapidly scale the model's dimensions. By scaling the main body 110 of the connector 100 proportionally using SFE-Concept software, the structural dimensions of the main body 110 of the connector 100 can be made consistent with those of the beam. This embodiment does not limit this approach. Proportional scaling is suitable for situations where the connector 100 and the beam have a high degree of matching. Compared to adjusting the dimensions of the transition section 140 to automatically update the dimensions of the main body 110, proportional scaling is more efficient. When the matching degree between the connector 100 and the beam is low, adjusting the dimensions of the transition section 140 is more suitable for adjusting the dimensions of the main body 110 of the connector 100.
[0055] Furthermore, this application also proposes a modular joint, which is constructed using the aforementioned modular joint construction method based on SFE-Concept software, to form a modular joint library within the SFE-Concept software. In other words, after modeling different types of joints 100 in the SFE-Concept software, it is no longer necessary to adjust or recreate the joint 100 model due to inconsistencies in the coding numbers of the beam connection section and the joint connection section 130 of the joint 100, or inconsistencies in the size ratio between the beam and the joint 100, thus saving considerable time. Instead, one only needs to select the joint 100 corresponding to the beam from the modular joint library and adjust the size of the joint 100 and the transition portion 120 accordingly, shortening the time required to build the vehicle body model within the SFE-Concept software.
