[0047] It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0048] Reference Figure 1 , Figure 1 A schematic diagram of the structure of a vehicle front windshield and ceiling gap design device in the hardware operating environment involved in an embodiment of the present invention.

Among them, the communication bus 1002 is used to realize the connection and communication between these components. The user interface 1003 may include a display screen (Display), an input unit such as a keyboard (Keyboard), and the optional user interface 1003 may also include a standard wired interface and a wireless interface. The network interface 1004 may optionally include a standard wired interface and a wireless interface (such as a wireless fidelity (Wireless-Fidelity, Wi-Fi) interface). The memory 1005 may be a high-speed random access memory (Random Access Memory, RAM) memory, or a stable non-volatile memory (Non-Volatile Memory, NVM), such as a disk memory. The memory 1005 may also be a storage device independent of the aforementioned processor 1001.

[0050] Those skilled in the art will understand that Figure 1 The structure shown in the figure does not constitute a limitation on the design device for the gap between the front windshield and the roof of the vehicle, and may include more or fewer components than shown in the figure, or a combination of certain components, or a different arrangement of components.

[0051] like Figure 1 As shown, the memory 1005 as a storage medium may include an operating system, a network communication module, a user interface module, and a vehicle front windshield and roof gap design program.

[0052] exist Figure 1 In the vehicle front windshield and roof gap design 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 the memory 1005 in the vehicle front windshield and roof gap design device of the present invention can be set in the vehicle front windshield and roof gap design device, and the vehicle front windshield and roof gap design device calls the vehicle front windshield and roof gap design program stored in the memory 1005 through the processor 1001, and executes the vehicle front windshield and roof gap design method provided by the embodiment of the present invention.

[0053] The embodiment of the present invention provides a method for designing the gap between the front windshield and the roof of a vehicle, referring to Figure 2 , Figure 2 The figure is a flow chart of a first embodiment of a method for designing a gap between a front windshield and a roof of a vehicle according to the present invention.

[0054] In this embodiment, the method for designing the gap between the front windshield and the roof of a vehicle comprises the following steps:

[0055] Step S10: Acquire process design information of the target vehicle, and construct a windshield ceiling gap space model according to the process design information, wherein the windshield ceiling gap space model is used to calculate the gap between the front windshield and the ceiling of the target vehicle.

[0056] In this embodiment, the execution subject of this embodiment can be the vehicle front windshield and ceiling gap design device, which has functions such as data processing, data communication and program running, and the vehicle front windshield and ceiling gap design device can be a computer or server or other intelligent terminal that can perform data processing and analysis. Of course, it can also be other devices with similar functions, and this implementation condition does not limit this. For the convenience of explanation, this embodiment takes the vehicle front windshield and ceiling gap design device as an example for explanation.

[0057] It should be noted that if the gap between the black edge of the car and the ceiling is designed to be too small, when assembling the ceiling, due to the accumulation of manufacturing tolerances, the ceiling and the black edge may interfere with each other and the ceiling may not be assembled; when the gap between the black edge and the ceiling is too large, people will appear in front of the car after the actual car comes out, and the ceiling flange will be leaking, resulting in poor visual effects; if the gap is too small, the cumulative manufacturing tolerance of the gap between the ceiling and the black edge can be calculated by 3DCS software, and the gap between the two designs can be avoided if it is greater than the calculated cumulative tolerance. When the gap is too large, it is necessary to use VRED software for digital model rendering to make the rendered digital model close to the actual state, and then simulate the gap splitting from the perspective of an adult in front of the car to observe whether the ceiling flange will be leaking. If it is leaking, it is necessary to improve the problem by reducing the gap or increasing the length of the black edge. The solution of this embodiment is adopted to realize the method of combining simulation calculation with rendering simulation, guide the design of the theoretical value of the gap between the black edge of the front windshield and the ceiling of the car, and reduce the time cost and economic cost of the later actual car due to the failure to achieve this aspect.

[0058] It should be understood that the process design information refers to the design process-related parameter information of each component and position of the target vehicle during the design stage.

[0059] In a specific implementation, the windshield ceiling gap space model is a space model pre-established in the simulation software, and the design scheme can be viewed and adjusted in real time after rendering.

[0060] Furthermore, in order to construct a windshield roof gap space model according to process design information, step S10 includes: obtaining process design information of the target vehicle; determining a process flow chart according to the process design information; determining a structure tree according to the process flow chart; and constructing a windshield roof gap space model according to the structure tree.

[0061] It should be noted that the process design information of the target vehicle is first obtained, and then the process flow chart is determined, the installation-related data is imported into CATIA, and the structure tree is processed according to the process flow chart. The completed geometric model is imported into the 3DCS software, and finally the windshield roof gap space model is obtained by combining the position of the front windshield and the roof position.

[0062] Furthermore, in order to accurately construct the calculation model and facilitate subsequent calculations and designs, the step of constructing a windshield ceiling gap space model based on the structure tree includes: determining the front windshield position and the ceiling position based on the structure tree; and constructing a windshield ceiling gap space model based on the front windshield position and the ceiling position.

[0063] It should be noted that the front windshield assembly is self-positioned on the vehicle body in the Z and X directions, and the Y direction is manually adjusted to ensure that the gap between the front windshield and the left and right sides of the body are consistent. Its positioning on the vehicle body can be simulated in the software using the "Highpoint" command in the "USER-DLL". The specific simulation assembly can be used Figure 3 T1~T7 in the figure represent: T1~T4 are combined to control the movement of the front windshield in the Z direction and the rotation around the X-axis and the Y-axis, controlling three degrees of freedom; T5~T6 are combined to control the movement of the front windshield in the X direction and the rotation around the Z-axis, controlling two degrees of freedom; T7a controls the gap between the front windshield and the right side of the side panel, and T7b controls the gap between the front windshield and the left side panel to ensure that the gaps between the front windshield and the left and right side panels are the same; T7a~T7b are combined to control the movement of the front windshield in the Y direction, controlling one degree of freedom, and combined with T1~T7b, the front windshield is completely positioned.

[0064] It should be understood that after the front windshield is assembled, the roof needs to be assembled in the software. The assembly of the roof in the software is simulated by the "Autobend" command in the "USER-DLL". Figure 4 Among them, T1~T4 are combined to control the movement of the roof on the white body in the Z direction, and the rotation around the Y axis and the X axis, with a total of 3 degrees of freedom. T5~T6 are respectively equipped with a positioning pin on the ceiling, which are combined to control the movement of the ceiling on the white body in the X direction and the rotation around the Z axis, with a total of two degrees of freedom; T7 is the positioning pin on the ceiling inserted into the body, controlling the movement of the ceiling in the Y direction, controlling one degree of freedom, and T1~T7 are combined to control the complete positioning of the ceiling.

[0065] Step S20: performing model rendering based on the windshield ceiling gap space model to obtain a simulation rendering result.

[0066] In the specific implementation, after the model is built, run "Run Analysis" in the software, and you can calculate that the 3 sigma tolerance of the car analysis is ±1.2mm. Then you can render it in the VRED software according to the ±1.2 gap.

[0067] Furthermore, in order to complete the rendering and obtain a simulation rendering result, step S20 includes: determining the body data and material data of the target vehicle according to the process design information; obtaining the environmental configuration information; and performing model rendering on the windshield ceiling gap space model according to the body data, the material data and the environmental configuration information to obtain a simulation rendering result.

[0068] It should be noted that the front windshield, roof and white body digital model in the body data are input into VRED. Combined with the material data, the white body of the conventional sedan model is made of metal, so they are given the "Metalic" command material in the software. For the above-calculated model, the overall appearance is pearl white, so the "Metalic pearlmut" command is used to give the front and rear doors appearance material, and then adjust its diffuse color, gloss color, roughness, white weave, etc. to make it consistent with the appearance of the real car. The front windshield is a transparent glass material, so it is given the material in the "Glass and Gems" command in the software. Then the front windshield is transparent, and the "Glass 80% transparent 3mm" material is given, and then its transparency, gloss color, etc. are adjusted. The adjusted one is shown in the figure below, so that it is consistent with the appearance of the real car. In order to better see the seam, the environment and light need to be adjusted next. The environment can use the system's own environment, and select the "Orange Seaview" environment. Next, the light brightness, contrast, saturation, etc. of the environment need to be adjusted. Normally adjust to 1.0.

[0069] Step S30: adjusting the design of the front windshield and the roof of the target vehicle according to the simulation rendering result to prevent the black edge of the front windshield from blocking the roof.

[0070] It should be understood that the specific method of adjusting the front windshield and roof design of the target vehicle according to the simulation rendering results is to compare the gap of the design theoretical value with the gap of the actual simulation, so as to determine whether to make design adjustments and the specific adjustment methods based on the comparison results and visual effects.

[0071] This embodiment obtains the process design information of the target vehicle, and constructs a windshield roof gap space model based on the process design information. The windshield roof gap space model is used to calculate the gap between the front windshield and the roof of the target vehicle; based on the windshield roof gap space model, the model is rendered to obtain a simulation rendering result; and the design of the front windshield and the roof of the target vehicle is adjusted according to the simulation rendering result to prevent the black edge of the front windshield from blocking the roof. In this way, a method of combining simulation calculation with rendering simulation is implemented to guide the design of the theoretical value of the gap between the black edge of the front windshield and the roof of the automobile, which can reduce the time cost and economic cost of changing the actual vehicle in the later stage due to failure to meet this aspect.

[0072] refer to Figure 5 , Figure 5 The figure is a flow chart of a second embodiment of a method for designing a gap between a front windshield and a roof of a vehicle according to the present invention.

[0073] Based on the first embodiment described above, the method for designing the gap between the front windshield and the roof of a vehicle in this embodiment includes, in step S30:

[0074] Step S301: determining a hypothetical gap of a seam design value according to the simulation rendering result.

[0075] It should be noted that after rendering according to the above process, the deviation results caused by the design value and the corresponding tolerance can be reviewed, mainly by viewing from different angles. Figure 6 The flushness at the seam is shown.

[0076] It should be understood that the design value of the split is Figure 7 As shown, it is 1.65. Theoretically, the ceiling cut edge cannot be seen from the front. Figure 7 As shown, the black edge of the front windshield will block the roof.

[0077] Step S302: Substitute the preset tolerance into the simulation rendering result to calculate and obtain the actual gap.

[0078] In a specific implementation, the actual gap is a calculation result with the tolerance substituted in. The specific tolerance is a preset tolerance. This embodiment uses ±1.2 mm as an example for illustration. It may also be other values, which are not limited in this embodiment.

[0079] Step S303: adjusting the design of the front windshield and the roof of the target vehicle according to the actual gap and the hypothetical gap.

[0080] It should be noted that after the values ​​of the actual gap and the hypothetical gap are determined, the two are compared to determine whether to proceed with the design of the front windshield and roof of the target vehicle, and how to make specific adjustments.

[0081] Furthermore, in order to accurately determine the design adjustment plan, step S303 includes: comparing the actual gap with the hypothetical gap; and determining the design adjustment plan for the front windshield and the roof of the target vehicle according to the comparison result.

[0082] It should be understood that the actual gap is first compared with the assumed gap value to determine the comparison result, and then the design adjustment plan of the front windshield and roof of the target vehicle is determined according to the difference in the comparison results.

[0083] In a specific implementation, the comparison results include two types, namely, the difference between the actual gap and the assumed gap does not meet the design condition, and the difference between the actual gap and the assumed gap meets the design condition. The design condition is whether the gap error of the split seam meets the preset error range.

[0084] Furthermore, in order to accurately determine the design adjustment plan, the step of determining the design adjustment plan for the front windshield and the roof of the target vehicle according to the comparison results includes: when the difference between the actual gap and the hypothetical gap in the comparison results does not meet the design conditions, obtaining the digital model information of the simulation rendering result; performing digital model movement in the rendering according to the digital model information, and if the roof is not blocked by the front windshield after the movement, adjusting the black edge length and the theoretical position of the roof of the target vehicle.

[0085] It should be noted that when the difference between the actual gap and the hypothetical gap in the comparison result does not meet the design conditions, that is, the error of the gap of the slit does not meet the preset error range, the digital model information of the simulation rendering result is first obtained.

[0086] It should be understood that when the calculated tolerance of ±1.2 is substituted, Figure 7 The 1.65 gap becomes 2.85, and the gap between the ceiling assembly and the black edge of the glass becomes larger. According to this situation, move the digital model in the rendering. If the black edge of the front windshield still blocks the ceiling after the movement, the design is considered qualified. Otherwise, the leakage of the ceiling cut edge can be solved by increasing the length of the black edge or moving the theoretical position of the ceiling back a certain distance. Specifically, first move the digital model to determine whether the leakage of the ceiling cut edge is caused by the position of the digital model. If the leakage of the ceiling cut edge cannot be solved after the movement, increase the value of the black edge length or adjust the theoretical position of the ceiling until the ceiling cut edge does not leak.

[0087] This embodiment determines the hypothetical gap of the design value of the split according to the simulation rendering result; substitutes the preset tolerance into the simulation rendering result to calculate and obtain the actual gap; and adjusts the design of the front windshield and the roof of the target vehicle according to the actual gap and the hypothetical gap. In this way, it is achieved to calculate and compare the simulation rendering results to determine whether the designed front windshield and roof meet the visual requirements, and adjust the design when they do not meet the requirements, thereby reducing the cost of adjusting the design plan and simplifying the optimization process.

[0088] In addition, an embodiment of the present invention also proposes a storage medium, on which a vehicle front windshield and ceiling gap design program is stored. When the vehicle front windshield and ceiling gap design program is executed by a processor, the steps of the vehicle front windshield and ceiling gap design method described above are implemented.

[0089] Since the storage medium adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.
