[0057] It should be understood that the specific embodiments described herein are intended to be illustrative only and not limiting of the present application.

[0058] Reference Figure 1 , Figure 1 The frameless door simulation model construction device structure schematic diagram of the hardware running environment related to the embodiment scheme of the present application.

[0059] As Figure 1As shown, the frameless car door simulation model building device may include: a processor 1001, such as a central processing unit (CPU), a communication bus 1002, a user interface 1003, a network interface 1004, and a memory 1005.

The memory 1005 may be high-speed random access memory (RAM) or stable non-volatile memory (NVM), such as a disk storage device. The memory 1005 may also optionally be a storage system independent of the aforementioned processor 1001.

[0060] Those skilled in the art will understand that Figure 1 The structure shown does not constitute a limitation on the frameless door simulation model building equipment, and may include more or fewer parts than shown, or combine certain parts, or have different part arrangements.

[0061] like Figure 1 As shown, the memory 1005, which serves as a storage medium, may include an operating system, a network communication module, a user interface module, and a frameless car door simulation model building program.

[0062] exist Figure 1 In the frameless car door simulation model building device shown, the network interface 1004 is mainly used for data communication with the network server; the user interface 1003 is mainly used for data interaction with the user; the processor 1001 and memory 1005 in the frameless car door simulation model building device of the present invention can be set in the frameless car door simulation model building device, and the frameless car door simulation model building device calls the frameless car door simulation model building program stored in the memory 1005 through the processor 1001 and executes the frameless car door simulation model building method provided in the embodiment of the present invention.

[0063] This invention provides a method for constructing a frameless car door simulation model, referring to... Figure 2 , Figure 2 This is a flowchart illustrating the first embodiment of the frameless car door simulation model construction method of the present invention.

[0064] In this embodiment, the method for constructing the frameless car door simulation model includes the following steps:

[0065] Step S10: Determine the initial tooling model of the rear door and the initial tooling model of the front door corresponding to the initial frameless door of the car.

[0066] It is easy to understand that the execution subject of this embodiment can be a frameless car door simulation model building device with functions such as data processing, network communication and program running, or other computer devices with similar functions. This embodiment does not limit it.

[0067] Compared to traditional framed glass cars, frameless glass car doors require higher manufacturing precision for two main reasons: First, for aesthetic purposes, the surface difference between the frameless glass and its surrounding components is relatively small, resulting in a smoother visual appearance. However, this necessitates minimizing the surface difference tolerances during manufacturing. Second, frameless doors expose more glass, offering a wider field of vision compared to framed doors. This necessitates better sealing to prevent air and water leaks. Minimizing the gap between the glass and surrounding components during the design phase effectively addresses this issue. Therefore, a well-designed Dimensional Technical Specifications (DTS) for frameless doors is crucial to controlling the surface difference and gaps around the perimeter.

[0068] In the specific implementation, the frameless glass installation data is imported into CATIA, and then the completed geometric model is imported into 3DCS software. The geometric model includes the initial tooling model of the rear door, the initial tooling model of the front door, the first hinge tooling model, and the second hinge tooling model.

[0069] Step S20: Adjust the initial tooling model of the rear door and the initial tooling model of the front door based on the hinge assembly strategy to obtain the rear door assembly and the front door assembly.

[0070] It should be noted that before adjusting the initial tooling models of the rear door and front door based on the hinge assembly strategy to obtain the rear door assembly and front door assembly, the first hinge tooling model should be determined based on the initial tooling model of the rear door, the second hinge tooling model should be determined based on the initial tooling model of the front door, the rear door hinge transfer strategy should be determined based on the initial tooling model of the rear door and the first hinge tooling model based on the rear door constraint points, the front door hinge assembly strategy should be determined based on the front door tooling model and the second hinge tooling model based on the front door constraint points, and the hinge assembly strategy should be generated based on the rear door hinge assembly strategy and the front door hinge assembly strategy.

[0071] Furthermore, the initial tooling models of the rear door and the front door are adjusted based on the hinge assembly strategy to obtain the rear door assembly and the front door assembly. The processing method is to extract the rear door hinge assembly strategy and the front door hinge assembly strategy from the hinge assembly strategy, then process the initial tooling model of the rear door through the first hinge according to the rear door hinge assembly strategy to obtain the rear door assembly, and process the initial tooling model of the front door through the second hinge according to the front door hinge assembly strategy to obtain the front door assembly.

[0072] Furthermore, according to the rear door hinge assembly strategy, the initial tooling model of the rear door is processed through the first hinge to obtain the rear door assembly. The processing method is as follows: according to the rear door hinge assembly strategy, the initial tooling model of the rear door is processed through the first hinge to obtain the rear door assembly to be processed. The rear door assembly to be processed is adjusted through the constraints of the rear door assembly to obtain the rear door assembly.

[0073] In practical implementation, to ensure the rear door hinge is installed on the rear door with guaranteed accuracy, a first hinge fixture model needs to be installed on the initial rear door fixture model. The first hinge fixture model is installed on the initial rear door fixture model using a self-positioning method, which can be achieved in 3DCS software using the "Si x Plane Move" command. The installation model is as follows: Figure 3 As shown, Figure 3 This is the rear door tooling model of the first embodiment of the frameless car door simulation model construction method of the present invention. Figure 1 , Figure 3 The first hinge fixture model is clamped onto the initial fixture model of the rear door via T1 to T3, controlling the movement of the first hinge fixture model in the Y direction and its rotation around the X and Z axes, thus restricting the fixture's three degrees of freedom. Two pins on the first hinge fixture model are inserted into two holes in the initial fixture model of the rear door, and T4 to T6 control the movement of the first hinge fixture model in the X and Z directions and its rotation around the Y axis, again restricting the fixture's three degrees of freedom. In this way, all six degrees of freedom of the hinge fixture are completely restricted.

[0074] It should be noted that the backdoor constraint points include T1, T2, T3, T4, T5, and T6.

[0075] The first hinge is installed onto the initial fixture model of the rear door using the first hinge fixture model assembled in the previous step. The Y and Z directions of the first hinge are positioned using the first hinge fixture model. The Y direction is directly tightened onto the rear door with bolts. Assembly can be simulated using the "Three Point Move" command in the software. The installation model is as follows: Figure 4 As shown, Figure 4 This is the rear door tooling model of the first embodiment of the frameless car door simulation model construction method of the present invention. Figure 2 In the diagram, T1 to T3 restrict the degrees of freedom of the upper hinge, and T4 to T6 restrict the degrees of freedom of the lower hinge.

[0076] After installing the first hinge on the rear door, it can be mounted onto the body-in-white, resulting in the rear door assembly to be processed. Then, align the gaps between the rear door and the body-in-white, tighten the hinge surfaces to the body-in-white, and the assembly of the rear door assembly is complete. This process can be completed in the software using the "Six Plane Move" command. (The installation model is shown below.) Figure 5 As shown, Figure 5 This is a diagram of the rear door assembly in the first embodiment of the frameless car door simulation model construction method of the present invention. In the diagram, T1 to T2 are hinges fastened to the car body, controlling the rear door assembly in the Y direction; T3 is manual smoothing of the car body and the door assembly, controlling the Y direction; T1 to T3 together control the Y-direction movement of the rear door assembly and its rotation around the X and Z axes, for a total of 3 degrees of freedom; T4 to T5 control the Z-direction movement of the rear door, and together control the rotation of the rear door around the Y axis; T6 is manual alignment of the gap between the rear door assembly and the car body, controlling the X-direction movement of the rear door assembly. The installation of the door assembly in the software is then completed.

[0077] It should also be understood that the rear door hinge assembly strategy involves clamping it onto the initial rear door tooling model via T1 to T3, controlling the movement of the first hinge tooling model in the Y direction and its rotation around the X and Z axes, thus restricting the tooling's three degrees of freedom. Two pins on the first hinge tooling model are inserted into two holes in the initial rear door tooling model, and T4 to T6 control the movement of the first hinge tooling model in the X and Z directions and its rotation around the Y axis, further restricting the tooling's three degrees of freedom. This completely restricts all six degrees of freedom of the hinge tooling.

[0078] The constraints for the rear door assembly are as follows: T1-T2 involve the hinges being tightened onto the vehicle body, controlling the rear door assembly in the Y direction; T3 involves manually smoothing the vehicle body and door assembly, controlling the Y direction; T1-T3 together control the Y-direction movement of the rear door assembly and its rotation around the X and Z axes, for a total of 3 degrees of freedom; T4-T5 control the Z-direction movement of the rear door, and together control the rotation of the rear door around the Y axis; T6 involves manually aligning the gap between the rear door assembly and the vehicle body, controlling the X-direction movement of the rear door assembly. This completes the installation of the door assembly in the software.

[0079] In this embodiment, the front door assembly is obtained by processing the initial tooling model of the front door through the second hinge according to the front door hinge assembly strategy. The processing method is as follows: the initial tooling model of the front door is processed through the second hinge according to the front door hinge assembly strategy to obtain the front door assembly to be processed. The front door assembly to be processed is adjusted through the constraints of the front door assembly to obtain the front door assembly.

[0080] In practical implementation, to ensure the second hinge is installed accurately on the front door, the second hinge fixture model needs to be installed on the initial front door fixture model first. The second hinge fixture model is installed on the initial front door fixture model using a self-positioning method, which can be achieved using the "Six Plane Move" command in 3DCS software. The installation model is as follows: Figure 6 As shown, Figure 6 This is the front door tooling model of the first embodiment of the frameless car door simulation model construction method of the present invention. Figure 1 In the diagram, the fixture is clamped onto the front door via T1 to T3, controlling its movement in the Y direction and its rotation around the X and Z axes, thus restricting the fixture's three degrees of freedom. Two pins on the fixture are inserted into two holes in the front door, as shown in Figures T4 to T6, controlling the fixture's movement in the X and Z directions and its rotation around the Y axis, thus restricting the fixture's three degrees of freedom. In this way, all six degrees of freedom of the front door hinge fixture are completely restricted.

[0081] The second hinge is installed onto the initial front door fixture model using the second hinge fixture model assembled in the previous step. The Y and Z axes of the second hinge are positioned by the fixture, and the Y axis is directly tightened onto the front door with bolts. Assembly can be simulated using the "ThreePoint Move" command in the software. The installation model is as follows: Figure 7 As shown, Figure 7 This is the front door tooling model of the first embodiment of the frameless car door simulation model construction method of the present invention. Figure 2 In the diagram, T1 to T3 restrict the degrees of freedom of the upper hinge, and T4 to T6 restrict the degrees of freedom of the lower hinge.

[0082] After the second hinge is installed on the front door, it can be mounted on the body-in-white. The actual assembly process for the front door is also manual. The gaps between the front and rear doors are aligned, and then the hinge surfaces are tightened to the body-in-white, completing the rear door assembly. This process can be completed in the software using the "Six Plane Move" command. (The installation model is shown below.) Figure 8 As shown, Figure 8 The first embodiment of the frameless car door simulation model construction method of the present invention is shown in the front door assembly diagram: T1~T2 are the hinges tightened on the car body, controlling the rear door assembly in the Y direction; T3 is the manual smoothing of the front and rear door assemblies, controlling the Y direction; T1~T3 together control the Y-direction movement of the front door assembly and its rotation around the X and Z axes, for a total of 3 degrees of freedom; T4~T5 control the Z-direction movement of the front door, and together control the rotation of the front door around the Y axis; T6 is the manual alignment of the gap between the front and rear door assemblies, controlling the X-direction movement of the front door assembly; the above completes the installation of the front door assembly in the software.

[0083] It should also be noted that the front door constraint points include T1, T2, T3, T4, T5 and T6.

[0084] It should also be understood that the front door hinge assembly strategy involves clamping the tooling onto the front door using T1 to T3, controlling the tooling's movement in the Y direction and its rotation around the X and Z axes, thus restricting the tooling's three degrees of freedom. Two pins on the tooling are inserted into two holes in the front door, controlling the tooling's movement in the X and Z directions and its rotation around the Y axis, again restricting the tooling's three degrees of freedom. This completely restricts all six degrees of freedom of the front door hinge tooling. T1 to T3 restrict the upper hinge's degrees of freedom, and T4 to T6 restrict the lower hinge's degrees of freedom.

[0085] The constraints for the front door assembly are as follows: T1-T2 are hinges fastened to the vehicle body, controlling the rear door assembly in the Y direction; T3 is manual smoothing of the front and rear door assemblies, controlling the Y direction; T1-T3 together control the Y-direction movement of the front door assembly and its rotation around the X and Z axes, for a total of 3 degrees of freedom; T4-T5 control the Z-direction movement of the front door, and together control the rotation of the front door around the Y axis; T6 is manual alignment of the gap between the front and rear door assemblies, controlling the X-direction movement of the front door assembly.

[0086] Step S30: Determine the front triangular window model based on the front door glass model using a preset front gap surface difference, and determine the rear triangular window model based on the rear door glass model using a preset rear gap surface difference.

[0087] In practice, glass guide rails are typically installed on the car doors in the final assembly workshop using a self-positioning method. The glass guide rails are placed inside the car door, and then the bolts are tightened. The assembly is relatively simple and can be completed using the "Step PlaneMove" function in the software.

[0088] After the glass guide rail is installed, the door glass can be installed on it. Because frameless glass requires high precision, tooling is used during assembly to adjust its X and Y axis position after installation. This can be done in the software using the "Six Plane Move" and "Dynamic Points" commands. The installation model is as follows... Figure 9 and 10 As shown, Figure 9 The front and rear door glass models are from the first embodiment of the frameless car door simulation model construction method of the present invention. Figure 1 , Figure 10 The front and rear door glass models are from the first embodiment of the frameless car door simulation model construction method of the present invention. Figure 2 T1 to T6 are for assembling the front door glass model using the "Six Plane Move" command; T7 and T8 use the "Dynamic Points" command to fit the virtual midpoint, and then combine with T9 to T13 to complete the assembly of the front door glass model using the "Six Plane Move" command.

[0089] The front quarter window model and the front door glass model have a direct gap surface difference fit, so the front quarter window glass needs to be installed in the model. Similarly, the rear quarter window model and the rear door glass model also have a direct gap surface difference fit, so the rear quarter window glass needs to be installed in the model. Both of these parts are self-positioned and installed on the vehicle body, which is relatively simple and can be completed using "Step PlaneMove".

[0090] Step S40: Construct a frameless door simulation model using body trim strips based on the front door assembly, the rear door assembly, the front door glass model, the rear door glass model, the front quarter window model, and the rear quarter window model.

[0091] Furthermore, the process of constructing a frameless door simulation model using body trim strips based on the front door assembly, rear door assembly, front door glass model, rear door glass model, front quarter window model, and rear quarter window model is as follows: A frameless door simulation model to be verified is generated using body trim strips based on the front door assembly, rear door assembly, front door glass model, rear door glass model, front quarter window model, and rear quarter window model. The circumferential gap tolerance and circumferential surface difference tolerance of the frameless door area are determined based on the frameless door simulation model. Adjustments are then made to the frameless door simulation model to be verified based on these tolerances to obtain the final frameless door simulation model.

[0092] In practical implementation, the body trim strips and front and rear door windows must directly overlap, and the quality of their assembly is closely related to the sealing performance. The body trim strips are relatively soft, and force can cause slight deformation. Therefore, the software needs to use "User-DLLMove" to simulate this deformation, making the simulation model more realistic. The installation model is as follows... Figure 11 , Figure 11 The first embodiment of the frameless car door simulation model construction method of the present invention shows the overlap diagram of the body trim strip and the front and rear door glass: the body trim strip moves in the Z direction by T1 to T4. The “User-DLL” command can simulate the deformation in one direction controlled by four mounting points. T1 to T4 together also control the rotation of the body trim strip around the X and Z axes. T5 to T7 control the movement of the body trim strip in the X and Z directions and the rotation around the Y axis.

[0093] It should also be noted that calculating the peripheral DTS of the frameless door area based on the simulation model of the frameless door to be verified guides the design of the peripheral DTS of the frameless glass in automobiles. This can effectively solve the problems of air and water leakage and aesthetics caused by unreasonable DTS design of frameless glass. Moreover, it provides guidance during the design stage, which can reduce the time and economic costs of making changes to the actual vehicle later due to non-compliance in these aspects. The peripheral DTS of the frameless door area includes the peripheral gap tolerance and the peripheral surface difference tolerance of the frameless door area. For example, to calculate the gap surface difference between the front door glass and the B-pillar trim panel, refer to... Figure 12 , Figure 12 This is a diagram of the front door glass and B-pillar trim panel in the first embodiment of the frameless car door simulation model construction method of the present invention. The gap in the DTS (Dimensional Scale) is defined as (8 + / - 1.5) mm, and the surface difference is defined as (0.5 + / - 1.5) mm. That is, the maximum cumulative gap tolerance and surface difference tolerance for this seam is 1.5 mm. The three-dimensional dimensional chain model established using 3DCS software can directly output the gap and surface difference tolerances, indicating whether the previously designed DTS is reasonable. If unreasonable, the design can be optimized or the precision of individual parts can be changed. This yields an optimized frameless car door simulation model. (Refer to...) Figure 13 , Figure 13 This is a simulation model diagram of a frameless car door, representing the first embodiment of the frameless car door simulation model construction method of the present invention.

[0094] In this embodiment, the initial tooling models for the rear door and front door corresponding to the initial frameless car door are first determined. Then, based on the hinge assembly strategy, the initial tooling models for the rear door and front door are adjusted to obtain the rear door assembly and the front door assembly. Next, the front triangular window model is determined based on the front door glass model using a preset front gap surface difference, and the rear triangular window model is determined based on the rear door glass model using a preset rear gap surface difference. Finally, a frameless car door simulation model is constructed using body trim strips based on the front door assembly, rear door assembly, front door glass model, rear door glass model, front triangular window model, and rear triangular window model. Compared to existing technologies that do not involve a method for constructing a frameless car door simulation model, this embodiment obtains the front and rear door assemblies, front and rear door glass models, and front and rear triangular window models based on the hinge assembly strategy and preset gap surface differences. Then, the corresponding frameless car door simulation model is constructed using body trim strips based on the front and rear door assemblies, front and rear door glass models, and front and rear triangular window models, thereby achieving rapid and accurate construction of the frameless car door simulation model.

[0095] Reference Figure 14 , Figure 14 This is a structural block diagram of the first embodiment of the frameless car door simulation model construction system of the present invention.

[0096] like Figure 14 As shown, the frameless car door simulation model construction system proposed in this embodiment of the invention includes:

[0097] The determination module 1401 is used to determine the initial tooling model of the rear door and the initial tooling model of the front door corresponding to the initial frameless door of the automobile.

[0098] Compared to traditional framed glass cars, frameless glass car doors require higher manufacturing precision for two main reasons: First, for aesthetic purposes, the surface difference between the frameless glass and its surrounding components is relatively small, resulting in a smoother visual appearance. However, this necessitates minimizing the surface difference tolerances during manufacturing. Second, frameless doors expose more glass, offering a wider field of vision compared to framed doors. This necessitates better sealing to prevent air and water leaks. Minimizing the gap between the glass and surrounding components during the design phase effectively addresses this issue. Therefore, a well-designed Dimensional Technical Specifications (DTS) for frameless doors is crucial to controlling the surface difference and gaps around the perimeter.

[0099] In the specific implementation, the frameless glass installation data is imported into CATIA, and then the completed geometric model is imported into 3DCS software. The geometric model includes the initial tooling model of the rear door, the initial tooling model of the front door, the first hinge tooling model, and the second hinge tooling model.

[0100] The adjustment module 1402 is used to adjust the initial tooling model of the rear door and the initial tooling model of the front door based on the hinge assembly strategy to obtain the rear door assembly and the front door assembly.

[0101] It should be noted that before adjusting the initial tooling models of the rear door and front door based on the hinge assembly strategy to obtain the rear door assembly and front door assembly, the first hinge tooling model should be determined based on the initial tooling model of the rear door, the second hinge tooling model should be determined based on the initial tooling model of the front door, the rear door hinge transfer strategy should be determined based on the initial tooling model of the rear door and the first hinge tooling model based on the rear door constraint points, the front door hinge assembly strategy should be determined based on the front door tooling model and the second hinge tooling model based on the front door constraint points, and the hinge assembly strategy should be generated based on the rear door hinge assembly strategy and the front door hinge assembly strategy.

[0102] Furthermore, the initial tooling models of the rear door and the front door are adjusted based on the hinge assembly strategy to obtain the rear door assembly and the front door assembly. The processing method is to extract the rear door hinge assembly strategy and the front door hinge assembly strategy from the hinge assembly strategy, then process the initial tooling model of the rear door through the first hinge according to the rear door hinge assembly strategy to obtain the rear door assembly, and process the initial tooling model of the front door through the second hinge according to the front door hinge assembly strategy to obtain the front door assembly.

[0103] Furthermore, according to the rear door hinge assembly strategy, the initial tooling model of the rear door is processed through the first hinge to obtain the rear door assembly. The processing method is as follows: according to the rear door hinge assembly strategy, the initial tooling model of the rear door is processed through the first hinge to obtain the rear door assembly to be processed. The rear door assembly to be processed is adjusted through the constraints of the rear door assembly to obtain the rear door assembly.

[0104] In practical implementation, to ensure the rear door hinge is installed on the rear door with guaranteed accuracy, a first hinge fixture model needs to be installed on the initial rear door fixture model. The first hinge fixture model is installed on the initial rear door fixture model using a self-positioning method, which can be achieved in 3DCS software using the "Si x Plane Move" command. The installation model is as follows: Figure 3 As shown, Figure 3 This is the rear door tooling model of the first embodiment of the frameless car door simulation model construction method of the present invention. Figure 1 , Figure 3 The first hinge fixture model is clamped onto the initial fixture model of the rear door via T1 to T3, controlling the movement of the first hinge fixture model in the Y direction and its rotation around the X and Z axes, thus restricting the fixture's three degrees of freedom. Two pins on the first hinge fixture model are inserted into two holes in the initial fixture model of the rear door, and T4 to T6 control the movement of the first hinge fixture model in the X and Z directions and its rotation around the Y axis, again restricting the fixture's three degrees of freedom. In this way, all six degrees of freedom of the hinge fixture are completely restricted.

[0105] It should be noted that the backdoor constraint points include T1, T2, T3, T4, T5, and T6.

[0106] The first hinge is installed onto the initial fixture model of the rear door using the first hinge fixture model assembled in the previous step. The Y and Z directions of the first hinge are positioned using the first hinge fixture model. The Y direction is directly tightened onto the rear door with bolts. Assembly can be simulated using the "Three Point Move" command in the software. The installation model is as follows: Figure 4 As shown, Figure 4 This is the rear door tooling model of the first embodiment of the frameless car door simulation model construction method of the present invention. Figure 2 In the diagram, T1 to T3 restrict the degrees of freedom of the upper hinge, and T4 to T6 restrict the degrees of freedom of the lower hinge.

[0107] After installing the first hinge on the rear door, it can be mounted onto the body-in-white, resulting in the rear door assembly to be processed. Then, align the gaps between the rear door and the body-in-white, tighten the hinge surfaces to the body-in-white, and the assembly of the rear door assembly is complete. This process can be completed in the software using the "Six Plane Move" command. (The installation model is shown below.) Figure 5 As shown, Figure 5This is a diagram of the rear door assembly in the first embodiment of the frameless car door simulation model construction method of the present invention. In the diagram, T1 to T2 are hinges fastened to the car body, controlling the rear door assembly in the Y direction; T3 is manual smoothing of the car body and the door assembly, controlling the Y direction; T1 to T3 together control the Y-direction movement of the rear door assembly and its rotation around the X and Z axes, for a total of 3 degrees of freedom; T4 to T5 control the Z-direction movement of the rear door, and together control the rotation of the rear door around the Y axis; T6 is manual alignment of the gap between the rear door assembly and the car body, controlling the X-direction movement of the rear door assembly. The installation of the door assembly in the software is then completed.

[0108] It should also be understood that the rear door hinge assembly strategy involves clamping it onto the initial rear door tooling model via T1 to T3, controlling the movement of the first hinge tooling model in the Y direction and its rotation around the X and Z axes, thus restricting the tooling's three degrees of freedom. Two pins on the first hinge tooling model are inserted into two holes in the initial rear door tooling model, and T4 to T6 control the movement of the first hinge tooling model in the X and Z directions and its rotation around the Y axis, further restricting the tooling's three degrees of freedom. This completely restricts all six degrees of freedom of the hinge tooling.

[0109] The constraints for the rear door assembly are as follows: T1-T2 involve the hinges being tightened onto the vehicle body, controlling the rear door assembly in the Y direction; T3 involves manually smoothing the vehicle body and door assembly, controlling the Y direction; T1-T3 together control the Y-direction movement of the rear door assembly and its rotation around the X and Z axes, for a total of 3 degrees of freedom; T4-T5 control the Z-direction movement of the rear door, and together control the rotation of the rear door around the Y axis; T6 involves manually aligning the gap between the rear door assembly and the vehicle body, controlling the X-direction movement of the rear door assembly. This completes the installation of the door assembly in the software.

[0110] In this embodiment, the front door assembly is obtained by processing the initial tooling model of the front door through the second hinge according to the front door hinge assembly strategy. The processing method is as follows: the initial tooling model of the front door is processed through the second hinge according to the front door hinge assembly strategy to obtain the front door assembly to be processed. The front door assembly to be processed is adjusted through the constraints of the front door assembly to obtain the front door assembly.

[0111] In practical implementation, to ensure the second hinge is installed accurately on the front door, the second hinge fixture model needs to be installed on the initial front door fixture model first. The second hinge fixture model is installed on the initial front door fixture model using a self-positioning method, which can be achieved using the "Six Plane Move" command in 3DCS software. The installation model is as follows: Figure 6 As shown, Figure 6 This is the front door tooling model of the first embodiment of the frameless car door simulation model construction method of the present invention. Figure 1In the diagram, the fixture is clamped onto the front door via T1 to T3, controlling its movement in the Y direction and its rotation around the X and Z axes, thus restricting the fixture's three degrees of freedom. Two pins on the fixture are inserted into two holes in the front door, as shown in Figures T4 to T6, controlling the fixture's movement in the X and Z directions and its rotation around the Y axis, thus restricting the fixture's three degrees of freedom. In this way, all six degrees of freedom of the front door hinge fixture are completely restricted.

[0112] The second hinge is installed onto the initial front door fixture model using the second hinge fixture model assembled in the previous step. The Y and Z axes of the second hinge are positioned by the fixture, and the Y axis is directly tightened onto the front door with bolts. Assembly can be simulated using the "ThreePoint Move" command in the software. The installation model is as follows: Figure 7 As shown, Figure 7 This is the front door tooling model of the first embodiment of the frameless car door simulation model construction method of the present invention. Figure 2 In the diagram, T1 to T3 restrict the degrees of freedom of the upper hinge, and T4 to T6 restrict the degrees of freedom of the lower hinge.

[0113] After the second hinge is installed on the front door, it can be mounted on the body-in-white. The actual assembly process for the front door is also manual. The gaps between the front and rear doors are aligned, and then the hinge surfaces are tightened to the body-in-white, completing the rear door assembly. This process can be completed in the software using the "Six Plane Move" command. (The installation model is shown below.) Figure 8 As shown, Figure 8 The first embodiment of the frameless car door simulation model construction method of the present invention is shown in the front door assembly diagram: T1~T2 are the hinges tightened on the car body, controlling the rear door assembly in the Y direction; T3 is the manual smoothing of the front and rear door assemblies, controlling the Y direction; T1~T3 together control the Y-direction movement of the front door assembly and its rotation around the X and Z axes, for a total of 3 degrees of freedom; T4~T5 control the Z-direction movement of the front door, and together control the rotation of the front door around the Y axis; T6 is the manual alignment of the gap between the front and rear door assemblies, controlling the X-direction movement of the front door assembly; the above completes the installation of the front door assembly in the software.

[0114] It should also be noted that the front door constraint points include T1, T2, T3, T4, T5 and T6.

[0115] It should also be understood that the front door hinge assembly strategy involves clamping the tooling onto the front door using T1 to T3, controlling the tooling's movement in the Y direction and its rotation around the X and Z axes, thus restricting the tooling's three degrees of freedom. Two pins on the tooling are inserted into two holes in the front door, controlling the tooling's movement in the X and Z directions and its rotation around the Y axis, again restricting the tooling's three degrees of freedom. This completely restricts all six degrees of freedom of the front door hinge tooling. T1 to T3 restrict the upper hinge's degrees of freedom, and T4 to T6 restrict the lower hinge's degrees of freedom.

[0116] The constraints for the front door assembly are as follows: T1-T2 are hinges fastened to the vehicle body, controlling the rear door assembly in the Y direction; T3 is manual smoothing of the front and rear door assemblies, controlling the Y direction; T1-T3 together control the Y-direction movement of the front door assembly and its rotation around the X and Z axes, for a total of 3 degrees of freedom; T4-T5 control the Z-direction movement of the front door, and together control the rotation of the front door around the Y axis; T6 is manual alignment of the gap between the front and rear door assemblies, controlling the X-direction movement of the front door assembly.

[0117] The determining module 1401 is further configured to determine the front triangular window model based on the front door glass model through a preset front gap surface difference, and to determine the rear triangular window model based on the rear door glass model through a preset rear gap surface difference.

[0118] In practice, glass guide rails are typically installed on the car doors in the final assembly workshop using a self-positioning method. The glass guide rails are placed inside the car door, and then the bolts are tightened. The assembly is relatively simple and can be completed using the "Step PlaneMove" function in the software.

[0119] After the glass guide rail is installed, the door glass can be installed on it. Because frameless glass requires high precision, tooling is used during assembly to adjust its X and Y axis position after installation. This can be done in the software using the "Six Plane Move" and "Dynamic Points" commands. The installation model is as follows... Figure 9 and 10 As shown, Figure 9 The front and rear door glass models are from the first embodiment of the frameless car door simulation model construction method of the present invention. Figure 1 , Figure 10 The front and rear door glass models are from the first embodiment of the frameless car door simulation model construction method of the present invention. Figure 2 T1 to T6 are for assembling the front door glass model using the "Six Plane Move" command; T7 and T8 use the "Dynamic Points" command to fit the virtual midpoint, and then combine with T9 to T13 to complete the assembly of the front door glass model using the "Six Plane Move" command.

[0120] The front quarter window model and the front door glass model have a direct gap surface difference fit, so the front quarter window glass needs to be installed in the model. Similarly, the rear quarter window model and the rear door glass model also have a direct gap surface difference fit, so the rear quarter window glass needs to be installed in the model. Both of these parts are self-positioned and installed on the vehicle body, which is relatively simple and can be completed using "Step PlaneMove".

[0121] The construction module 1403 is used to construct a frameless door simulation model based on the front door assembly, the rear door assembly, the front door glass model, the rear door glass model, the front triangular window model, and the rear triangular window model using body trim strips.

[0122] Furthermore, the process of constructing a frameless door simulation model using body trim strips based on the front door assembly, rear door assembly, front door glass model, rear door glass model, front quarter window model, and rear quarter window model is as follows: A frameless door simulation model to be verified is generated using body trim strips based on the front door assembly, rear door assembly, front door glass model, rear door glass model, front quarter window model, and rear quarter window model. The circumferential gap tolerance and circumferential surface difference tolerance of the frameless door area are determined based on the frameless door simulation model. Adjustments are then made to the frameless door simulation model to be verified based on these tolerances to obtain the final frameless door simulation model.

[0123] In practical implementation, the body trim strips and front and rear door windows must directly overlap, and the quality of their assembly is closely related to the sealing performance. The body trim strips are relatively soft, and force can cause slight deformation. Therefore, the software needs to use "User-DLLMove" to simulate this deformation, making the simulation model more realistic. The installation model is as follows... Figure 11 , Figure 11 The first embodiment of the frameless car door simulation model construction method of the present invention shows the overlap diagram of the body trim strip and the front and rear door glass: the body trim strip moves in the Z direction by T1 to T4. The “User-DLL” command can simulate the deformation in one direction controlled by four mounting points. T1 to T4 together also control the rotation of the body trim strip around the X and Z axes. T5 to T7 control the movement of the body trim strip in the X and Z directions and the rotation around the Y axis.

[0124] It should also be noted that calculating the peripheral DTS of the frameless door area based on the simulation model of the frameless door to be verified guides the design of the peripheral DTS of the frameless glass in automobiles. This effectively solves the problems of air and water leakage and aesthetics caused by unreasonable DTS design of frameless glass. Furthermore, this guidance is provided during the design phase, reducing the time and economic costs of later modifications to the actual vehicle due to non-compliance in these aspects. The peripheral DTS of the frameless door area includes the peripheral gap tolerance and the peripheral surface difference tolerance of the frameless door area. For example, calculating the gap surface difference between the front door glass and the B-pillar trim panel can be referenced... Figure 12 , Figure 12This is a diagram of the front door glass and B-pillar trim panel in the first embodiment of the frameless car door simulation model construction method of the present invention. The gap in the DTS (Dimensional Scale) is defined as (8 + / - 1.5) mm, and the surface difference is defined as (0.5 + / - 1.5) mm. That is, the maximum cumulative gap tolerance and surface difference tolerance for this seam is 1.5 mm. The three-dimensional dimensional chain model established using 3DCS software can directly output the gap and surface difference tolerances, indicating whether the previously designed DTS is reasonable. If unreasonable, the design can be optimized or the precision of individual parts can be changed. This yields an optimized frameless car door simulation model. (Refer to...) Figure 13 , Figure 13 This is a simulation model diagram of a frameless car door, representing the first embodiment of the frameless car door simulation model construction method of the present invention.

[0125] In this embodiment, the initial tooling models for the rear door and front door corresponding to the initial frameless car door are first determined. Then, based on the hinge assembly strategy, the initial tooling models for the rear door and front door are adjusted to obtain the rear door assembly and the front door assembly. Next, the front triangular window model is determined based on the front door glass model using a preset front gap surface difference, and the rear triangular window model is determined based on the rear door glass model using a preset rear gap surface difference. Finally, a frameless car door simulation model is constructed using body trim strips based on the front door assembly, rear door assembly, front door glass model, rear door glass model, front triangular window model, and rear triangular window model. Compared to existing technologies that do not involve a method for constructing a frameless car door simulation model, this embodiment obtains the front and rear door assemblies, front and rear door glass models, and front and rear triangular window models based on the hinge assembly strategy and preset gap surface differences. Then, the corresponding frameless car door simulation model is constructed using body trim strips based on the front and rear door assemblies, front and rear door glass models, and front and rear triangular window models, thereby achieving rapid and accurate construction of the frameless car door simulation model.
