Description

Technical Field

[0001] The present invention relates to the technical field of vehicle door design, and more specifically, to a method, device, and storage medium for checking the movement clearance of door panel trim parts. Background Art

[0002] Checking of moving parts is an important link in the automotive styling stage. Especially during the opening process of the front and middle door panels of a vehicle, decorative parts installed on the door panels, such as rearview mirrors, anti-scratch strips, anti-collision strips, etc., will generate movement clearances with fixed parts in the environment. If the clearance size is too small or there is interference during the movement of the door panel, it will not only affect the styling state of the door panel and decorative parts, but also have an impact on the clearance setting between products.

[0003] In the development of existing body products in the automotive industry, Catia software is usually used. During the product development process, data is generally used to intercept cross-sections, and then the position of the door hinge is defined for rotational measurement. This measurement method has a large deviation and there is a risk of checking errors. Especially in the case where there are installation tolerances for components, there are checking misunderstandings in this intercepted cross-section, and the risk points cannot be completely and comprehensively identified. There will be an interference risk when the product is installed in the vehicle. For example, there are usually two upper and lower hinges for a vehicle door. During the actual installation process, there will be installation deviations for the upper and lower hinges, which will exacerbate the error. If only in the ideal state, there will be an interference risk. Summary of the Invention

[0033] It should be noted that in this text, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device.

[0034] Embodiment 1

[0035] To solve the above problems, a method for checking the movement clearance of a door panel trim is provided. By using the "DMU Kinematics" module in Catia software, the movement clearance of the door panel trim is checked, and the minimum clearance, position and angle information are automatically output. As Figure 1 shown, the specific description of the checking method of the present invention is as follows:

[0036] S1. Extract the parameter data of the fender, door panel and trim according to the target automotive styling stage model. Taking the front fender, front door panel and front anti-scratch strip as an example, obtain the parameter data of the automotive styling stage model of the front fender, front door panel and front anti-scratch strip. Among them, the front fender is a fixed part, the front door panel is a moving part, and the front anti-scratch strip is installed at the lower part of the front door panel and moves synchronously with the front door panel as a plastic trim.

[0037] S2. Obtain the surface profile accuracy, hinge installation position and positional tolerance of the door panel and fender; define the door hinge opening angle θ1; define the minimum safety clearance D for the door hinge opening;

[0038] In the specific implementation process, according to the experience of the reference vehicle model, the surface profile accuracy of the front fender and front door panel is 1.0; the hinge installation positional tolerance is 0.6; the door hinge opening angle θ1 is defined as 63°; the minimum safety clearance for the door hinge opening is defined as D = 2.5 mm.

[0039] S3. Assemble the fender, door panel and trim into the "DMU Kinematics" module in Catia software respectively, and establish a mechanical device and simulation in the "DMU Kinematics" module in Catia software.

[0040] S31. Define the rotation axis according to the theoretical installation position and installation position tolerance of the upper and lower hinges.

[0041] Determine the theoretical installation positions and installation position tolerances of the upper and lower hinges. Determine the limit positions of the upper and lower hinges according to the installation position tolerances and theoretical positions of the upper and lower hinges, and adjust the installation positions of the upper and lower hinges respectively according to the limit positions. Extract the center points of the rotation shafts of the upper and lower hinges respectively, and connect the upper and lower center points to obtain the rotation axis.

[0042] In addition to the theoretical installation position and installation position tolerance, the tolerance of the hinge positioning holes will also affect the rotation axis. During the specific implementation process, according to the tolerance of the hinge positioning holes, offset the upper hinge a set distance towards the inside of the vehicle, and offset the lower hinge a set distance towards the outside of the vehicle.

[0043] S32. Construct a mechanical device through the cooperation of the fender, door panel and decorative parts. Among them, for the theoretical installation position and installation position tolerance of the decorative parts, determine the limit position of the decorative parts according to the installation position tolerance and theoretical position of the decorative parts, adjust the installation position of the decorative parts according to the limit position of the decorative parts, and select the installation tolerance of the installation parts with smaller gaps. Utilize the obtained rotation axis, combine geometric figures, establish a rotational joint, and set the angle limit to θ1 in the rotational joint according to the defined door hinge opening angle θ1.

[0044] In the example: a) Use the fixed command in catia to fix the fender, and set the "rigid connection" between the front door panel and the anti-scratch strip; b) Establish a rotational joint, utilize the rotation axis obtained in step "S31", combine geometric figures, and establish a rotational joint; according to step "S2" to define the door hinge opening angle θ1, and set the angle limit to θ1 in the rotational joint.

[0045] S33. Configure the dimension simulation for the gaps of concern. Specifically, a) Edit the "Distance and Region Analysis" to define the gaps of concern; b) Through the "Activate Sensor" command in the "Mechanical Device", select the positions where the gaps need to be measured, activate the measurement command, so as to output the gap dimensions in real time during the motion simulation process.

[0046] S34. Simulate and analyze the gap distances of concern within the door hinge opening angle range of 0 - θ1.

[0047] During the specific implementation process, for the gap distances within the door hinge opening angle range of 0 - θ1 in the simulation, construct a relationship diagram between the gap distances and the opening angles.

[0048] Figure 3 In the shown example, the front fender, front door panel, and front anti-scratch strip are assembled into the "DMU Kinematics" module in the catia software, and a mechanical device and simulation are established in the "DMU Kinematics" module in the catia software. Figure 4 In the shown example, a relationship diagram between the gap distances and the opening angles is given.

[0049] S4. Feasibility Judgment of the Target Automotive Styling Stage Model:

[0050] Traverse the gap distance S in the relationship diagram output by the simulation, evaluate the numerical size of each gap distance S and the minimum safety gap D, and judge: If any gap distance S ≥ the minimum safety gap D within the hinge opening angle range of 0 - θ1, the surfaces of the door panel and the trim are feasible, and the data verification of the target automotive styling stage model passes; if there exists a gap distance S < the minimum safety gap D within the hinge opening angle range of 0 - θ1, adjust the DTS value between products to increase the gap between the products in the automotive styling stage model data; or adjust the surfaces of the door panel and the trim of the automotive styling stage model, and then repeat the simulation command until any gap distance S ≥ the minimum safety gap D within the hinge opening angle range of 0 - θ1.

[0051] In the specific implementation process, adjust the surfaces of the products that contribute to the gap factors in sequence according to the profile tolerance value of the door panel surface. For example, if the profile tolerance contribution deviation dimension of the front fender is S1, then offset the surface of the front fender by S1; if the profile tolerance contribution dimension of the front door panel is S2, then offset the surface of the front door panel by S2...

[0052] In the example, according to the catia simulation results, within the range of the front door panel opening angle of 0 - 63°, the gap distance S is 2.7 mm, and the minimum safety gap D = 2.5 mm. Since the gap distance S ≥ the minimum safety gap D, the surfaces of the front door panel and the anti - scratch strip are feasible.

[0053] When there is a trim on the door panel, the present invention supports confirming the maximum opening angle θ of the door. By confirming the maximum opening angle of the door, it is convenient to adjust the opening setting value of the hinge, improving the comfort of the vehicle owner getting on and off the vehicle. For example Figure 2 As shown, the process of judging the maximum opening angle is as follows:

[0054] For the rotational joint in the "mechanical device", set the maximum angle in the limiting angle to 90°; execute the "simulation" command in the "mechanical device" to obtain the relationship diagram between the simulated gap distance and the opening angle of the mechanical device; in the said relationship diagram, judge the position where the gap distance S is equal to the minimum safety gap D, and the minimum angle θ among all the angles corresponding to the non - extreme positions at the above - mentioned positions is the maximum opening angle of the door.

[0055] In the example of the given relationship diagram, within the range of 0 - 90°, there is one position where the gap distance S = the minimum safety gap D and it is a non - extreme position, and its angle θ = 65°, which is the maximum opening angle of the door. When the minimum safety gap D is 2.7 mm, within the range of 0 - 90°, there are two positions where the gap distance S = the minimum safety gap D. One is between 30 - 40, which is an extreme point, and the other is slightly less than 63°.
