Description

Technical Field

[0001] This invention relates to the field of automotive technology, specifically to a design method and manufacturing method for the inner panel of the upper side beam of a vehicle body. Background Technology

[0002] The upper side beam system of the vehicle body involves design indicators such as the vehicle's collision performance, functional layout, and process route. The upper side beam system includes the inner panel structure from the A-pillar position of the front hood of the vehicle engine to the rear triangular side window position, and is mainly the internal connection structure of the vehicle body above the vehicle window glass.

[0003] The inner panel of the upper side beam of the vehicle body involves the functional layout of components such as collision safety curtain airbags, roof wiring harnesses, built-in safety handles, interior dome lights, and sunroof connecting brackets. At the same time, the structure of the inner panel of the upper side beam also involves scheme-based issues such as stamping and forming of vehicle body parts, welding process routes, and installation accuracy. Usually, because various engineering problems conflict with each other in the early stages of design, the design work can only proceed step by step and cannot proceed to the next step of design work. This results in long design cycles, repeated changes to parts, and conventional design ideas can no longer meet the needs of the current consumer market with rapid product updates and iterations.

[0004] Therefore, how to reduce the design cycle of the inner panel of the upper side beam of the vehicle body and design a product with good stability has become one of the urgent technical problems to be solved. Summary of the Invention

[0005] This invention provides a design method and manufacturing method for the inner panel of the upper side beam of a vehicle body, which solves the technical problems of long design cycle and repeated modification of parts in related technologies.

[0006] According to the first aspect of this application, a design method for the inner panel of the upper side beam of a vehicle body is provided, comprising: obtaining a target styling surface of a target vehicle model, the target styling surface including: a windshield styling surface, a side panel styling surface, a roof panel styling surface, and a door glass styling surface; obtaining the upper boundary of the A-pillar area based on the windshield styling surface; the upper boundary of the A-pillar area is the boundary shape and setting position of the A-pillar mating with the windshield; obtaining the upper boundary of the B-pillar area and the upper boundary of the C-pillar area based on the side panel styling surface and the roof panel styling surface; the upper boundary of the B-pillar area is the boundary shape and setting position of the B-pillar mating with the roof, and the upper boundary of the C-pillar area is the boundary shape and setting position of the C-pillar mating with the roof. The installation location is determined; based on the door glass profile, the lower boundaries of the A-pillar, B-pillar, and C-pillar areas are obtained; the lower boundaries of these areas are the boundary shapes and installation locations of their interaction with the door glass; the mounting surface angles are determined, including: the mounting angles between the A-pillar and the windshield, and between the A-pillar and the door glass; the mounting angles between the B-pillar and the roof, and between the B-pillar and the door glass; the mounting angles between the C-pillar and the roof, and between the C-pillar and the door glass; based on the upper boundaries of the A-pillar area, the upper boundaries of the B-pillar area, the upper boundaries of the C-pillar area, the lower boundaries of the A-pillar area, the lower boundaries of the B-pillar area, the lower boundaries of the C-pillar area, and the mounting surface angles, the inner panel of the upper side beam of the vehicle body is designed.

[0007] Based on the aforementioned technical means, the design method for the inner panel of the upper side beam of the vehicle body in this application can obtain the upper and lower boundaries of the A-pillar, B-pillar, and C-pillar regions by using the front windshield molding surface, side outer panel molding surface, roof outer panel molding surface, and door glass molding surface that mate with the inner panel of the upper side beam of the vehicle body as a basis. That is, it obtains the boundary shapes and placement positions of the front windshield, side outer panel, roof outer panel, and door glass that mate with the inner panel of the upper side beam of the vehicle body. Finally, the inner panel of the upper side beam of the vehicle body is designed based on the mounting surface angle and the upper and lower boundaries of the A-pillar, B-pillar, and C-pillar regions. This invention can quickly carry out the part design work for the inner panel regions of the A, B, and C pillars of the upper body through preliminary molding surfaces, which helps to shorten the design cycle of the inner panel of the upper side beam of the vehicle body, while obtaining a standard-compliant inner panel of the upper side beam of the vehicle body.

[0008] In one possible implementation, the upper boundary of the A-pillar area is obtained based on the windshield profile, including: based on the windshield profile, windshield thickness, and windshield sealant thickness, the boundary shape of the A-pillar and the windshield is obtained according to a first standard section; the first standard section is the first normal section of the A-pillar, and the first normal section passes through the reference point of the driver's seat.

[0009] Based on the aforementioned technical means, this application constructs a three-dimensional structure of the windshield and windshield sealant by using the windshield styling surface, windshield thickness, and windshield sealant thickness. The boundary shape of the A-pillar mating with the windshield can be obtained by using the first standard cross-section of the three-dimensional structure of the windshield and windshield sealant. The boundary shape of the A-pillar mating with the windshield obtained by this method has good compatibility with the windshield, thereby improving the design accuracy of the inner panel of the upper side beam of the vehicle body.

[0010] In one possible implementation, obtaining the upper boundary of the A-pillar area based on the windshield's shaped surface further includes: obtaining the A-pillar's setting position by using a standard matching gap value between the black edge of the windshield, the lace edge of the windshield, and the thickness of the interior trim panel, with the obstruction angle passing through it; the obstruction angle is used to indicate the A-pillar obstruction angle.

[0011] Based on the aforementioned technical means, the obstruction angle of vision is used to construct the windshield's installation area using the standard matching gap values ​​between the black edge of the windshield, the frosted edge of the windshield, and the thickness of the interior trim panel, thereby determining the A-pillar's installation position. Since the black edge of the windshield, the frosted edge of the windshield, and the thickness of the interior trim panel are all located at the edge of the windshield, and part of the windshield's edge mates with the A-pillar, the obstruction angle of vision can accurately determine the A-pillar's installation position through this edge position of the windshield, further improving the design precision of the inner panel of the upper side beam of the vehicle body.

[0012] In one possible implementation, obtaining the upper boundary of the B-pillar area and the upper boundary of the C-pillar area based on the side panel outer shape surface and the roof outer panel outer shape surface includes: obtaining the upper boundary of the B-pillar area and the upper boundary of the C-pillar area based on the side panel outer shape surface and the roof outer panel outer shape surface and according to a second standard section; the second standard section is the second normal section of the roof, and the second normal section passes through the reference point of the seat.

[0013] Similarly, this application, based on the side panel outer shape and the roof outer panel shape, obtains the boundary shape and setting position of the B-pillar and the roof, as well as the boundary shape and setting position of the C-pillar and the roof, according to the second normal section of the roof. The boundary shapes of the B-pillar and the roof, and the boundary shapes of the C-pillar and the roof obtained by this method have good adaptability, thereby improving the design accuracy of the inner panel of the upper side beam of the vehicle body.

[0014] In one possible implementation, obtaining the lower boundaries of the A-pillar, B-pillar, and C-pillar areas based on the door glass molding surface and the sealing surfaces of the front and rear door openings includes: obtaining the lower boundaries of the A-pillar, B-pillar, and C-pillar areas based on the door glass molding surface and the sealing surfaces of the front and rear door openings.

[0015] Based on the above-mentioned technical means, this application obtains the boundary shape and setting position of the A-pillar, B-pillar, C-pillar and the door glass by using the door glass shaped surface and the sealing stop surface of the front and rear door opening frames.

[0016] In one possible implementation, obtaining the target styling surface of the target vehicle model includes: obtaining the target styling surface from the vehicle styling surface of the target vehicle model.

[0017] Based on the above technical means, the target styling surface of this application can be directly obtained from the automotive styling surface of the target vehicle model, and obtaining the target styling surface is simple and convenient.

[0018] In one possible implementation, determining the mounting surface angle includes: determining the mounting surface angle based on the overall layout ergonomics and standard cross-section design values, with the standard gap of the welding clamps in the welding process as the basic requirement.

[0019] The fit between the inner panel of the upper side beam of the vehicle body and other components (e.g., windshield, roof, door glass, etc.) in this application conforms to the overall layout human-machine verification and standard cross-sectional design values ​​of the vehicle, and takes into account the standard gap of the welding clamp in the welding process, so as to further improve the design accuracy of the inner panel of the upper side beam of the vehicle body.

[0020] According to a second aspect provided in this application, a method for manufacturing an inner panel of the upper side beam of a vehicle body is provided, comprising: the design method for the inner panel of the upper side beam of the vehicle body described in the first aspect above, wherein after designing the inner panel of the upper side beam of the vehicle body, the manufacturing method further comprises: manufacturing the designed inner panel of the upper side beam of the vehicle body.

[0021] Based on the aforementioned technical means, the manufacturing method of the inner panel of the upper side beam of the vehicle body in this application can obtain the upper and lower boundaries of the A-pillar, B-pillar, and C-pillar regions by using the front windshield molding surface, side outer panel molding surface, roof outer panel molding surface, and door glass molding surface that mate with the inner panel of the upper side beam of the vehicle body as a basis. That is, it obtains the boundary shape and setting position of the front windshield, side outer panel, roof outer panel, and door glass that mate with the inner panel of the upper side beam of the vehicle body. Finally, the inner panel of the upper side beam of the vehicle body is designed according to the mounting surface angle and the upper and lower boundaries of the A-pillar, B-pillar, and C-pillar regions, and the designed inner panel of the upper side beam of the vehicle body is manufactured. This invention can quickly carry out the parts manufacturing work of the inner panel regions of the A, B, and C pillars of the upper body through the preliminary molding surface, which helps to shorten the design cycle of the inner panel of the upper side beam of the vehicle body, while obtaining a standard inner panel of the upper side beam of the vehicle body.

[0022] In one possible implementation, the manufacturing of the designed upper side beam inner panel of the vehicle body includes: disassembling the designed upper side beam inner panel into multiple parts according to process constraints for manufacturing; and welding the multiple parts into a single piece to obtain the upper side beam inner panel of the vehicle body.

[0023] Due to limitations in material utilization and manufacturing processes, it may be impossible to manufacture the inner panel of the upper side beam of the vehicle body if it is directly set as a single structure. Therefore, this application disassembles the inner panel of the upper side beam of the vehicle body into multiple parts according to process limitations, and then welds these multiple parts into a single piece, thus facilitating the manufacturing of the inner panel of the upper side beam.

[0024] Therefore, the above-mentioned technical features of this application have the following beneficial effects:

[0025] (1) The design method of the inner panel of the upper side beam of the vehicle body in this application can obtain the upper and lower boundaries of the A-pillar, B-pillar, and C-pillar regions based on the front windshield shaping surface, side outer panel shaping surface, roof outer panel shaping surface, and door glass shaping surface that cooperate with the inner panel of the upper side beam of the vehicle body. That is, it obtains the boundary shape and setting position of the front windshield, side outer panel, roof outer panel, and door glass that cooperate with the inner panel of the upper side beam of the vehicle body. Finally, the inner panel of the upper side beam of the vehicle body is designed according to the mounting surface angle and the upper and lower boundaries of the A-pillar, B-pillar, and C-pillar regions. This invention can quickly carry out the part design work of the inner panel region of the A, B, and C pillars of the upper body through the preliminary shaping surface, which is conducive to shortening the design cycle of the inner panel of the upper side beam of the vehicle body, and at the same time obtaining the inner panel of the upper side beam of the vehicle body that meets the standards.

[0026] (2) This application constructs a three-dimensional structure of the windshield and windshield sealant by means of the windshield shaped surface, the windshield thickness and the windshield sealant thickness. The boundary shape of the A-pillar and the windshield can be obtained by the first standard section of the three-dimensional structure of the windshield and the windshield sealant. The boundary shape of the A-pillar and the windshield obtained by this method has good compatibility with the windshield, thereby improving the design accuracy of the inner panel of the upper side beam of the vehicle body.

[0027] (3) The field of vision obstruction angle of this application is constructed by using the standard matching gap value between the black edge of the windshield, the lace edge of the windshield, and the thickness of the interior trim panel to determine the installation area of ​​the windshield, thereby determining the installation position of the A-pillar. Since the black edge of the windshield, the lace edge of the windshield, and the thickness of the interior trim panel are all located at the edge of the windshield, and part of the edge of the windshield matches the A-pillar, the field of vision obstruction angle can accurately determine the installation position of the A-pillar through the edge position of the windshield, thereby further improving the design accuracy of the inner panel of the upper side beam of the vehicle body.

[0028] (4) This application obtains the boundary shape and setting position of the B-pillar and the roof, as well as the boundary shape and setting position of the C-pillar and the roof, based on the side panel outer shape surface and the roof outer shape surface, and according to the second normal section of the roof. The boundary shapes of the B-pillar and the roof and the C-pillar and the roof obtained by this method have good adaptability, thereby improving the design accuracy of the inner panel of the upper side beam of the vehicle body.

[0029] (5) The target styling surface of this application can be directly obtained from the automotive styling surface of the target vehicle model, and the target styling surface is simple and convenient to obtain.

[0030] (6) The fit between the inner panel of the upper side beam of the vehicle body and other components (e.g., windshield, roof, door glass, etc.) conforms to the overall layout human-machine verification and standard cross-sectional design values ​​of the vehicle, and takes into account the standard gap of the welding clamp in the welding process, so as to further improve the design accuracy of the inner panel of the upper side beam of the vehicle body.

[0031] (7) The manufacturing method of the inner panel of the upper side beam of the vehicle body in this application can obtain the upper and lower boundaries of the A-pillar, B-pillar, and C-pillar regions based on the front windshield molding surface, side outer panel molding surface, roof outer panel molding surface, and door glass molding surface that mate with the inner panel of the upper side beam of the vehicle body. That is, it obtains the boundary shape and setting position of the front windshield, side outer panel, roof outer panel, and door glass that mate with the inner panel of the upper side beam of the vehicle body. Finally, the inner panel of the upper side beam of the vehicle body is designed according to the mounting surface angle, the upper and lower boundaries of the A-pillar, B-pillar, and C-pillar regions, and the designed inner panel of the upper side beam of the vehicle body is manufactured. This invention can quickly carry out the parts manufacturing work of the inner panel regions of the A, B, and C pillars of the upper body through the preliminary molding surface, which is conducive to shortening the design cycle of the inner panel of the upper side beam of the vehicle body, and at the same time obtaining the inner panel of the upper side beam of the vehicle body that meets the standards.

[0032] (8) Due to limitations in material utilization and manufacturing processes, it may be impossible to manufacture the inner panel of the upper side beam of the vehicle body if it is directly set as a single structure. Therefore, this application manufactures the inner panel of the upper side beam of the vehicle body by disassembling it into multiple parts according to process limitations, and then welding the multiple parts into a single piece. This facilitates the manufacturing of the inner panel of the upper side beam. Attached Figure Description

[0041] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0042] It should be noted that the terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0043] The upper side beam system of the vehicle body involves design indicators such as the vehicle's collision performance, functional layout, and manufacturing process. The upper side beam system includes the inner panel structure from the A-pillar position of the front engine hood to the rear triangular side window position (i.e., the inner panel of the upper side beam of the vehicle body), which is mainly the internal connection structure of the vehicle body above the vehicle window glass.

[0044] The inner panel of the upper side beam of the vehicle body involves the functional layout of components such as collision safety curtain airbags, roof wiring harnesses, built-in safety handles, interior dome lights, and sunroof connecting brackets. At the same time, the structure of the inner panel of the upper side beam also involves scheme-based issues such as stamping and forming of vehicle body parts, welding process routes, and installation accuracy. Usually, because various engineering problems conflict with each other in the early stages of design, the design work can only proceed step by step and cannot proceed to the next step of design work. This results in long design cycles, repeated changes to parts, and conventional design ideas can no longer meet the needs of the current consumer market with rapid product updates and iterations.

[0045] The current conventional design method for the inner panel of the side wall upper beam derives the overlap trend of each component of the upper inner panel of columns A, B, and C from cross-sections at different locations. However, in the initial design phase, the angle values ​​of the inner panel's trajectory, inferred from the external and internal shapes, vary significantly between different locations. This results in uneven overlaps between inner panel components derived from individual cross-sections, requiring substantial time for adjustment and smoothing after data completion. Consequently, this leads to repeated modifications to component designs, repeated checks of manufacturability, and repeated verification of design layout. This results in a long design cycle for the inner panel of the side wall upper beam, repeated component modifications, poor robustness, increased design costs and timelines, and low design efficiency.

[0046] Therefore, how to quickly achieve a short design cycle for the inner panel of the upper side beam of the vehicle body and design a product with good stability has become one of the urgent technical problems to be solved.

[0047] Based on this, this application provides a design method and manufacturing method for the inner panel of the upper side beam of a vehicle body, which solves the technical problems of long design cycle and repeated modification of parts in the related art.

[0048] For ease of understanding, the design method and manufacturing method of the inner plate of the upper side beam of the vehicle body provided in this application will be described in detail below with reference to the accompanying drawings.

[0049] Firstly, embodiments of this application provide a design method for the inner panel of the upper side beam of a vehicle body, such as... Figure 1 As shown, the design method of the inner panel of the upper side beam of the vehicle body can include the following steps S201-S206.

[0050] S201. Obtain the target styling surface of the target vehicle model. The target styling surface may include: the windshield styling surface, the side panel styling surface, the roof panel styling surface, and the door glass styling surface.

[0051] The target vehicle model refers to the vehicle model that requires the design of the inner panel of the upper side beam of the vehicle body. Figure 2 This application provides a schematic diagram of the structure of a vehicle according to an embodiment of the present application. Figure 2As shown, the windshield styling surface 101 is the styling surface of the vehicle's windshield, the side panel styling surface 102 is the styling surface of the exterior side of the vehicle, the roof panel styling surface 103 is the styling surface of the exterior roof of the vehicle, and the door glass styling surface 104 is the styling surface of the vehicle's doors and door glass. These target styling surfaces can be obtained from the styling department.

[0052] In one possible implementation, obtaining the target styling surface of the target vehicle model can include: obtaining the target styling surface from the vehicle styling surface of the target vehicle model. That is, directly obtaining the target styling surface from the vehicle styling surface of the target vehicle model. In this way, obtaining the target styling surface is simple and convenient.

[0053] Optionally, the obtained styling surface can be a preliminary styling surface of the car, or it can be a final styling surface of the car. This application does not limit the specific type of surface.

[0054] S202. Obtain the upper boundary of the A-pillar area based on the shape of the windshield.

[0055] The upper boundary of the A-pillar area refers to the shape and position of the boundary where the A-pillar mates with the windshield. In other words, the upper boundary of the A-pillar area includes both the shape of the boundary where the A-pillar mates with the windshield and the position of the A-pillar.

[0056] In one possible implementation, such as Figure 3 As shown, step S202 may include the following steps S2021-S2022.

[0057] S2021. Based on the windshield profile, windshield thickness, and windshield sealant thickness, the boundary shape of the A-pillar and the windshield is obtained according to the first standard section.

[0058] Figure 4 This application provides a schematic diagram of the structure of an inner panel of the upper side beam of a vehicle body, as shown in the embodiment of this application. Figure 2 and Figure 4 As shown, the first standard section 105 is the first normal section of the A-pillar, and this first normal section passes through the reference point of the driver's seat. The reference point of the driver's seat is also known as point R, which refers to the reference point of the front driver's seat.

[0059] This application constructs a three-dimensional structure of the windshield and windshield sealant by using the windshield styling surface, windshield thickness, and windshield sealant thickness. The boundary shape of the A-pillar mating with the windshield can be obtained by using the first standard cross-section of the three-dimensional structure of the windshield and windshield sealant. The boundary shape of the A-pillar mating with the windshield obtained by this method has good compatibility with the windshield, thereby improving the design accuracy of the inner panel of the upper side beam of the vehicle body.

[0060] S2022. The A-pillar setting position is obtained by using the standard matching gap value between the black edge of the windshield, the lace edge of the windshield, and the thickness of the interior trim panel, based on the obstruction angle of vision.

[0061] Among them, such as Figure 2 As shown, the obstruction angle 106 is used to indicate the obstruction angle of the A-pillar. That is, the angle of vision that a person of average height can see from the left side from the driving position. For example, the angle of this obstruction angle can be less than 6°.

[0062] Additionally, it's understandable that the A-pillar typically has a mounting plate that mates with the windshield. This plate is parallel to the windshield and usually has silicone sealant applied to it. Since the windshield is usually transparent, this can easily expose the sealant, which tends to yellow over time, affecting the vehicle's overall appearance. Therefore, a black border is typically installed at the edge of the windshield (where it meets the mounting plate) to cover the connection between the plate and the windshield. This black border is the windshield black border, and the decorative border is the boundary between the black border and the transparent windshield. The interior trim panel is located on the A-pillar and is situated inside the vehicle.

[0063] Thus, the field of vision obstruction angle of this application constructs the installation area of ​​the windshield using the standard matching gap value between the black edge of the windshield, the frosted edge of the windshield, and the thickness of the interior trim panel, thereby determining the installation position of the A-pillar. Since the black edge of the windshield, the frosted edge of the windshield, and the thickness of the interior trim panel are all located at the edge of the windshield, and part of the edge of the windshield mates with the A-pillar, the field of vision obstruction angle can accurately determine the installation position of the A-pillar through the edge position of the windshield, thereby further improving the design accuracy of the inner panel of the upper side beam of the vehicle body.

[0064] S203. Based on the side panel outer shape and the roof panel outer shape, obtain the upper boundary of the B-pillar area and the upper boundary of the C-pillar area.

[0065] The upper boundary of the B-pillar area refers to the shape and position of the B-pillar mating with the roof, and the upper boundary of the C-pillar area refers to the shape and position of the C-pillar mating with the roof. In other words, the upper boundary of the B-pillar area includes both the shape of the B-pillar mating with the roof and the position of the B-pillar. Similarly, the upper boundary of the C-pillar area includes both the shape of the C-pillar mating with the roof and the position of the C-pillar.

[0066] In one possible implementation, such as Figure 5 As shown, step S203 may include the following step S2031.

[0067] S2031. Based on the side panel outer shape and the roof panel outer shape, the upper boundary of the B-pillar area and the upper boundary of the C-pillar area are obtained according to the second standard section.

[0068] The second standard section is the second normal section of the roof, which passes through the reference point of the seat. For example, Figure 2 and Figure 4 As shown, the second normal section may include: a front normal section 107 and a rear normal section 111, wherein the front normal section 107 is a normal section of the roof passing through the reference point of the front driver's seat, and the rear normal section 111 is a normal section of the roof passing through the reference point of the rear passenger's seat.

[0069] It is understandable that the B-pillar can fit with the roof, but the placement of the roof must ensure that the interior space of the vehicle meets standards, such as... Figure 2 As shown, the interior space of the vehicle may include: a standard headroom 108 for a driver of standard height in the front row (hereinafter referred to as the front headroom) and a standard headroom 109 for a passenger of standard height in the rear row (hereinafter referred to as the rear headroom).

[0070] Therefore, in some embodiments, step S2031 may include: based on the side panel outer shape surface, the roof outer panel shape surface, and the vehicle interior activity space, obtaining the upper boundary of the B-pillar area and the upper boundary of the C-pillar area according to the second standard section.

[0071] In one possible implementation, the upper boundary of the B-pillar area is obtained based on the side panel outer shape, the roof outer panel shape, and the front headroom, according to the front normal section. That is, since the roof is located between the roof outer panel and the front headroom, the three-dimensional structure of the roof is determined by the outer roof outer panel shape and the front headroom. Then, based on the front normal section, the boundary shape of the B-pillar and the roof is determined. Finally, the placement of the B-pillar is determined by the side panel outer panel shape.

[0072] In another possible implementation, the upper boundary of the C-pillar area is obtained based on the side panel outer shape, the roof outer panel shape, and the rear headroom, according to the normal section through the rear row. Similarly, since the roof is located between the roof outer panel and the rear headroom, the three-dimensional structure of the roof is determined by the outer roof outer panel shape and the rear headroom. Then, the boundary shape of the B-pillar and the roof is determined according to the normal section through the rear row. Finally, the placement position of the B-pillar is determined by the side panel outer panel shape.

[0073] In addition, the connection between the inner panel of the B-pillar and the roof, as well as the connection between the inner panel of the C-pillar and the roof, are subject to welding process limitations (e.g., welding channel, welding edge width, etc.). Therefore, in order to improve the design accuracy of the inner panel of the upper side beam of the vehicle body, in some other embodiments, step S2031 may also include: based on the outer panel of the side wall, the outer panel of the roof, the head movement space, and welding process limitations, obtaining the upper boundary of the B-pillar area and the upper boundary of the C-pillar area according to the second standard section.

[0074] This embodiment of the application, based on the side panel outer shape surface and the roof outer panel shape surface, obtains the boundary shape and setting position of the B-pillar and the roof, as well as the boundary shape and setting position of the C-pillar and the roof, according to the second normal section of the roof. The boundary shapes of the B-pillar and the roof and the C-pillar and the roof obtained by this method have good adaptability, thereby improving the design accuracy of the inner panel of the upper side beam of the vehicle body.

[0075] S204. Based on the shape of the door glass, obtain the lower boundary of the A-pillar, B-pillar and C-pillar areas.

[0076] The lower boundary of the area refers to the shape and position of its interaction with the door glass. Specifically, the lower boundary of the A-pillar area refers to the shape and position of the A-pillar interacting with the door glass, the lower boundary of the B-pillar area refers to the shape and position of the B-pillar interacting with the door glass, and the lower boundary of the C-pillar area refers to the shape and position of the C-pillar interacting with the door glass.

[0077] In some embodiments, such as Figure 5 As shown, step S204 may include the following step S2041.

[0078] S2041. Based on the door glass molding surface and the sealing surface of the front and rear door opening frames, obtain the lower boundaries of the A-pillar, B-pillar, and C-pillar areas. Among them, such as... Figure 2 As shown, the sealing stop surface 110 of the front door opening is the wall surface that seals with the door glass, and the sealing stop surface of the rear door opening is the wall surface that seals with the rear door glass.

[0079] Thus, this application can obtain the boundary shape and setting position of the A-pillar, B-pillar, C-pillar and the door glass by using the door glass shaped surface and the sealing stop surface of the front and rear door opening frames.

[0080] Since the vehicle door openings need to meet the requirements for entry and exit when the driver gets in the car, the size of the front and rear door openings can be determined. The shape of the door glass is usually fixed. Whether it is a frameless door or a framed door, the lower boundary of the A-pillar, B-pillar, and C-pillar areas can be obtained through the sealing relationship between the door glass and the vehicle body.

[0081] Therefore, in one possible implementation, the sealing surfaces of the front and rear door opening frames can be obtained by: using the door glass profile, based on the overall layout human-machine accessibility check, and using the standard cross-sectional definition values ​​of the door and window frames and the window frame sealing gaps.

[0082] S205. Determine the angle of the mounting surface.

[0083] The mounting surface angles may include: the mounting angle between the A-pillar and the windshield, and the mounting angle between the A-pillar and the door glass; the mounting surface angles in the B-pillar area include: the mounting angle between the B-pillar and the roof, and the mounting angle between the B-pillar and the door glass; the mounting surface angles in the C-pillar area include: the mounting angle between the C-pillar and the roof, and the mounting angle between the C-pillar and the door glass.

[0084] In one possible implementation, step S104, determining the mounting surface angle, may include: determining the mounting surface angle based on the overall layout ergonomics verification and standard cross-sectional values, using the standard gap of the welding clamp as a basic requirement. In other words, the mounting surface angle is subject to three limitations: First, the design of the mounting surface angle must meet accessibility requirements and the interior space must meet standard verification requirements. Second, the design of the mounting surface angle is constrained by the standardization of components. Third, the design of the mounting surface angle is limited by the standard gap of the welding clamp, meaning the design of the mounting surface angle cannot cause interference to the welding clamp during welding.

[0085] This shortens the design cycle of the inner panel of the upper side beam of the vehicle body and ensures that the designed inner panel of the upper side beam of the vehicle body has good stability.

[0086] S206. Based on the upper boundary of the A-pillar area, the upper boundary of the B-pillar area, the upper boundary of the C-pillar area, the lower boundary of the A-pillar area, the lower boundary of the B-pillar area, the lower boundary of the C-pillar area, and the angle of the mounting surface, design the inner panel of the upper side beam of the vehicle body.

[0087] Among them, such as Figure 2 and Figure 4 As shown, the inner panel 112 of the upper side beam of the vehicle body can be an integral piece, or alternatively, the inner panel 112 of the upper side beam of the vehicle body can be segmented. This application does not limit this.

[0088] The design method for the inner panel of the upper side beam of the vehicle body in this application can obtain the upper and lower boundaries of the A-pillar, B-pillar, and C-pillar regions based on the shaped surfaces of the windshield, outer side panels, outer roof panels, and door windows that mate with the inner panel of the upper side beam. That is, it obtains the boundary shapes and positions of the windshield, outer side panels, outer roof panels, and door windows that mate with the inner panel of the upper side beam. Finally, the inner panel of the upper side beam is designed based on the mounting surface angle and the upper and lower boundaries of the A-pillar, B-pillar, and C-pillar regions. This invention can quickly carry out the part design work for the inner panel regions of the A, B, and C pillars of the upper body through preliminary styling, which helps to shorten the design cycle of the inner panel of the upper side beam and obtain a standard-compliant inner panel of the upper side beam.

[0089] Secondly, embodiments of this application provide a method for manufacturing the inner panel of the upper side beam of a vehicle body, comprising: the design method for the inner panel of the upper side beam of the vehicle body described in the first aspect above; furthermore, after designing the inner panel of the upper side beam of the vehicle body, as... Figure 6 As shown, the manufacturing method may further include:

[0090] S301, Manufacturing the inner panel of the upper side beam of the designed vehicle body.

[0091] That is, the upper side beam of the vehicle body is manufactured according to the design.

[0092] The manufacturing method of the inner panel of the upper side beam of the vehicle body disclosed in this application can obtain the upper and lower boundaries of the A-pillar, B-pillar, and C-pillar regions based on the shaped surfaces of the windshield, side outer panels, roof outer panels, and door glass that mate with the inner panel of the upper side beam of the vehicle body. That is, it obtains the boundary shapes and positions of the windshield, side outer panels, roof outer panels, and door glass that mate with the inner panel of the upper side beam of the vehicle body. Finally, the inner panel of the upper side beam of the vehicle body is designed based on the mounting surface angle and the upper and lower boundaries of the A-pillar, B-pillar, and C-pillar regions, and the designed inner panel of the upper side beam of the vehicle body is manufactured. This invention can quickly carry out the parts manufacturing work of the inner panel regions of the A, B, and C pillars of the upper body through preliminary styling, which helps to shorten the design cycle of the inner panel of the upper side beam of the vehicle body, while obtaining a standard-compliant inner panel of the upper side beam of the vehicle body.

[0093] In one possible implementation, such as Figure 7 As shown, step S301 may include the following steps S3011-S3012.

[0094] S3011. The upper beam inner plate of the design is disassembled into multiple parts for production according to process constraints.

[0095] S3012. Multiple parts are welded together to form an integral part, so as to obtain the inner panel of the upper side beam of the vehicle body.

[0096] Due to limitations in material utilization and manufacturing processes, it may be impossible to manufacture the inner panel of the upper side beam of the vehicle body if it is directly set as a single structure. Therefore, this application manufactures the inner panel of the upper side beam of the vehicle body by disassembling it into multiple parts according to process limitations, and then welding these parts together to form a single unit. This facilitates the manufacturing of the inner panel of the upper side beam of the vehicle body.

[0097] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
