Description

Technical Field

[0001] The invention relates to the technical field of automobile manufacturing, and in particular to a method for determining a door hinge posture and an automobile. Background Art

[0002] In the industrialization stage of automobile development, due to the existence of manufacturing tolerances of parts, there are always some situations that cannot be considered in the design during assembly. Some tolerances cannot be measured after assembly due to space reasons, and the measurement before assembly cannot correspond to the actual vehicle situation after assembly. For example, the inner gap between the four doors (front door, right front door, rear door, right rear door) of the car and the body after assembly. After assembly, the inner gap between the sealing strip surface of the four doors and the body can be measured when the doors are closed (the size of this gap directly affects whether the assembly of the four doors is OK. If the gap is large, the sealing is not good and there is a risk of water leakage. If the gap is small, the interference of the sealing strip is large, which will cause the door to have a heavy closing force, so This gap must be within the control range), but after the car door is closed, the inner gap will be blocked. The second sealer needs to use a gap gauge inside the car to barely measure it, and due to the obstruction of the molded surface, the size of the inner gap cannot be accurately measured. As for the first seal, it is completely blocked and cannot be measured; before assembly, the two sealing surfaces can be measured separately, and measurements are performed on the four doors and the body respectively, but the four doors are not self-positioning during the assembly process. The four-door outer panels are aligned by tooling, and the door outer panels are assembled under the premise of ensuring the appearance. The inner gap is on the four-door inner panels, so after the four doors are assembled, the size of the inner gap cannot be accurately judged by the data measured before assembly.

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0042] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of the features.

Taking "A and / or B" as an example, it includes solution A, solution B, or solutions that satisfy both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0043] The present invention provides a method for determining the posture of a door hinge, aiming to solve the problem that after the four doors of an existing automobile are assembled, the size of the inner gap cannot be accurately determined by the data measured before assembly.

[0044] See also Figure 1 In a first embodiment of the present invention, the method for determining the door hinge posture comprises:

[0045] S100, obtaining a triangulated model of the vehicle body and the vehicle door;

[0046] It is understandable that after the vehicle door is installed on the vehicle body, it is not convenient to detect the gap between the vehicle door and the vehicle body. Therefore, before the vehicle door is formally installed on the vehicle body, the gap after installation is obtained in advance through virtual modeling and matching.

[0047] It should be noted that the present invention does not limit the specific scheme for obtaining the triangulated model. In one embodiment of the present invention, the triangulated model of the vehicle body and the vehicle door can be obtained by surveying and modeling. In another embodiment of the present invention, the vehicle body and the vehicle door can be scanned by a blue light scanning device, so that the triangulated model of the vehicle body and the vehicle door can be directly output by the blue light scanning device.

[0048] Specifically, in this embodiment, the vehicle body and the vehicle door are scanned by a blue light scanning device to output a triangulated model.

[0049] S200, determining a connection relationship between the vehicle body model 1 and the vehicle door model 2, and connecting the vehicle door model 2 to the vehicle body model 1 according to the connection relationship;

[0050] It is understandable that the body model 1 and the door model 2 output by the blue light scanning device are independent of each other. Therefore, in order to measure the gap between the body model 1 and the door model 2, the door model 2 needs to be installed on the body model 1 first.

[0051] At this time, the connection relationship between the vehicle body model 1 and the vehicle door model 2 is determined according to the actual condition of the vehicle door being installed on the vehicle body, and then the vehicle door model 2 can be connected to the vehicle body model 1 according to the connection relationship to simulate the actual condition of the vehicle door being installed on the vehicle body in the form of a virtual model.

[0052] It should be further explained that when the vehicle door is installed on the vehicle body, the vehicle door can rotate relative to the vehicle body so that the vehicle door has an open state and a closed state during its rotation stroke. However, when the vehicle door is in the open state, the vehicle door is away from the vehicle body. At this time, the gap between the vehicle door and the vehicle body cannot be measured.

[0053] Since the door model 2 is installed on the body model 1 to simulate the actual situation of the door being installed on the body, when the door model 2 is in an open state, the gap between the door model 2 and the body model 1 cannot be measured. Therefore, when the door model 2 is installed on the body model 1, the door model 2 should be stationary relative to the body model 1, and the door model 2 should be in a closed state.

[0054] S300, detecting an inner gap value between the door model 2 and the vehicle body model 1;

[0055] It can be understood that there are multiple locations between the door model 2 and the body model 1 where the inner gap values ​​need to be detected, and the distance between the door model 2 and the body model 1 is determined by multiple inner gap values.

[0056] Of course, the present invention does not limit the specific method for measuring the inner gap value between the door model 2 and the body model 1. In one embodiment of the present invention, the measuring points can be arranged by inputting the coordinates of the measuring points between the door model 2 and the body model 1.

[0057] S400: Determine the door hinge posture according to the inner gap value.

[0058] After the distance between the door model 2 and the body model 1 is determined jointly by multiple inner gap values, the distance between the door model 2 and the body model 1 indicates the distance between the door and the body after the door is installed on the body, which is the door hinge posture.

[0059] In the technical solution of the present invention, it is first necessary to obtain the triangulated models of the vehicle body and the door to obtain the vehicle body model 1 and the door model 2, and determine the connection relationship between the vehicle body model 1 and the door model 2. According to the connection relationship, the door model 2 is connected to the vehicle body model 1. After the vehicle body model 1 and the door model 2 are connected, the inner gap value between the door model 2 and the vehicle body model 1 is detected, and the inner gap value indicates the posture of the door hinge. In this way, the virtual matching method is used to measure the inner gap value between the door model 2 and the vehicle body model 1 to obtain the actual gap after the door is installed on the vehicle body. According to the inner gap value, the door hinge is adjusted to ensure that the gap between the door and the vehicle body is within the qualified range, thereby determining the posture of the door hinge.

[0060] It should also be noted that after the door hinge posture is determined, the door posture can be corrected by the door hinge posture to achieve correction of the door so that the door posture reaches the design value.

[0061] In the second embodiment of the present invention, please refer to Figure 2 The step S100 of obtaining the triangulated model of the vehicle body and the door includes:

[0062] S110 , scanning the vehicle body and the vehicle door by using a blue light scanning device to output the vehicle body model 1 and the vehicle door model 2 .

[0063] In the technical solution of this embodiment, the body model 1 and the door model 2 are output by a blue light scanning device, which can improve the accuracy of the body model 1 and the door model 2 relative to the body and the door, thereby further ensuring the accuracy of determining the door hinge posture through the body model 1 and the door model 2.

[0064] Of course, in the step of scanning the vehicle body and the door by the blue light scanning device to output a triangulated model, it is necessary to use software for simulation. The present invention is not limited to the specific software. In one embodiment of the present invention, Geomagic software can be used; in another embodiment of the present invention, RapidForm can also be used; and in another embodiment of the present invention, polyworks software or other software with three-dimensional scanning and modeling functions can also be used. In actual setting, it can be selected according to needs.

[0065] In the third embodiment of the present invention, please refer to Figure 3 The door model 2 includes a front door model 22 and a rear door model 21. The step S200 of determining a connection relationship between the vehicle body model 1 and the door model 2, and connecting the door model 2 to the vehicle body model 1 according to the connection relationship, includes:

[0066] S210, determining a rear door connection relationship between the rear door model 21 and the vehicle body model 1, and connecting the vehicle body model 1 and the rear door model 21 according to the rear door connection relationship;

[0067] It can be understood that in the actual process of installing the car door to the car body, the rear door needs to be installed first and then the front door. Therefore, when determining the connection relationship between the car door model 2 and the car body model 1, it is necessary to determine the rear door connection relationship between the rear door model 21 and the car body model 1, and then determine the front door connection relationship between the front door model 22 and the car body model 1.

[0068] Specifically, in this embodiment, the rear door is first installed on the vehicle body, and then the front door is installed on the vehicle body.

[0069] At this time, the rear door connection relationship between the vehicle body model 1 and the rear door model 21 is determined according to the actual condition of the rear door being installed on the vehicle body. Then, the rear door model 21 can be connected to the vehicle body model 1 according to the rear door connection relationship to simulate the actual condition of the rear door being installed on the vehicle body in the form of a virtual model.

[0070] When the rear door is mounted on the vehicle body, the rear door can rotate relative to the vehicle body so that the rear door has an open state and a closed state during its rotation stroke. However, when the rear door is in the open state, the rear door is away from the vehicle body. At this time, the gap between the rear door and the vehicle body cannot be measured.

[0071] Since the rear door model 21 is installed on the body model 1 to simulate the actual situation of the rear door being installed on the body, when the rear door model 21 is in an open state, the gap between the rear door model 21 and the body model 1 cannot be measured. Therefore, when the rear door model 21 is installed on the body model 1, the rear door model 21 should be stationary relative to the body model 1, and the rear door model 21 should be in a closed state.

[0072] S220, determining a front door connection relationship between the front door model 22 and the vehicle body model 1, and connecting the vehicle body model 1 and the front door model 22 according to the front door connection relationship.

[0073] When determining the front door connection relationship between the front door model 22 and the vehicle body model 1, the front door connection relationship between the vehicle body model 1 and the front door model 22 is determined according to the actual condition of the front door being installed on the vehicle body. Then, the front door model 22 can be connected to the vehicle body model 1 according to the front door connection relationship to simulate the actual condition of the front door being installed on the vehicle body in the form of a virtual model.

[0074] Similarly, when the front door is mounted on the vehicle body, the front door can rotate relative to the vehicle body so that the front door has an open state and a closed state during its rotation stroke. However, when the front door is in the open state, the front door is away from the vehicle body. At this time, the gap between the front door and the vehicle body cannot be measured.

[0075] Since the front door model 22 is installed on the body model 1 to simulate the actual situation of the front door being installed on the body, when the front door model 22 is in an open state, the gap between the front door model 22 and the body model 1 cannot be measured. Therefore, when the front door model 22 is installed on the body model 1, the front door model 22 should be stationary relative to the body model 1, and the front door model 22 should be in a closed state.

[0076] In the fourth embodiment of the present invention, please refer to Figure 4 The step S210, determining the backdoor connection relationship between the backdoor model 21 and the vehicle body model 1, and connecting the vehicle body model 1 and the backdoor model 21 according to the backdoor connection relationship, comprises:

[0077] S211, selecting a plurality of rear door degree of freedom feature points on both the rear door model 21 and the vehicle body model 1;

[0078] It can be understood that the rear door freedom feature point is the activity limit point of the rear door model 21 relative to the body model 1, and the setting of multiple rear door freedom feature points is used to jointly limit the activity of the rear door model 21 relative to the body model 1.

[0079] S212, setting the rear door model 21 in one-to-one correspondence with a plurality of rear door degree of freedom feature points on the vehicle body model 1;

[0080] It can be understood that the rear door model 21 corresponds one-to-one to the multiple rear door degree of freedom feature points on the body model 1, so that the relative position of the rear door model 21 and the body model 1 can be determined, thereby avoiding angle deviation or position deviation when the rear door model 21 is installed on the body model 1, thereby causing deviation in the measurement of the gap value.

[0081] S213 , setting rear door deviation values ​​of the two rear door degree of freedom feature points corresponding to the rear door model 21 and the vehicle body model 1 .

[0082] It should be noted that the rear door deviation value is the distance between the position of the rear door degree of freedom feature point on the rear door model 21 and the corresponding rear door degree of freedom feature point on the body model 1. For example, when the rear door deviation value is set to 0, it indicates that the corresponding two rear door degree of freedom feature points coincide with each other, that is, the rear door model 21 abuts against the body model 1.

[0083] In the technical solution of the present embodiment, it is first necessary to obtain a plurality of degree-of-freedom feature points on the rear door model 21 and the vehicle body model 1, and the plurality of degree-of-freedom feature points on the rear door model 21 are set in one-to-one correspondence with the plurality of degree-of-freedom feature points on the vehicle body model 1 to determine the relative position and relative angle of the connection between the rear door model 21 and the vehicle body model 1, and then set the rear door deviation value of the two corresponding degree-of-freedom feature points on the rear door model 21 and the vehicle body model 1 to determine the posture of the rear door model 21 installed on the vehicle body model 1, which is the posture of the rear door actually installed on the vehicle body, so as to ensure the accuracy of the determination of the door hinge posture.

[0084] Furthermore, in the invention, there is no restriction on the specific number of the rear door freedom feature points. It should be noted that among the multiple rear door freedom feature points, it is only necessary to ensure that each rear door freedom feature point corresponds to restricting the movement or rotation of the rear door in one direction.

[0085] At this time, the backdoor deviation value is the distance between the corresponding two degree-of-freedom feature points in the restricted activity direction.

[0086] Specifically, in this embodiment, the number of the rear door freedom feature points is set to 6, and the 6 rear door freedom feature points respectively restrict the movement or rotation of the rear door model 21 in various directions. That is, among the 6 rear door freedom feature points, three of the rear door freedom feature points respectively restrict the movement of the rear door model 21 along the X direction, Y direction, and Z direction of the vehicle body model 1; the other three rear door freedom feature points respectively restrict the rotation of the rear door model 21 around the extension lines of the X direction, Y direction, and Z direction of the vehicle body model 1.

[0087] In the fifth embodiment of the present invention, please refer to Figure 5 The step S220, determining the front door connection relationship between the front door model 22 and the vehicle body model 1, and connecting the vehicle body model 1 and the front door model 22 according to the front door connection relationship, comprises:

[0088] S221, selecting a plurality of front door degree of freedom feature points on both the front door model 22 and the vehicle body model 1;

[0089] It can be understood that the front door freedom feature point is the activity limit point of the front door model 22 relative to the body model 1, and the setting of multiple front door freedom feature points is used to jointly limit the activity of the front door model 22 relative to the body model 1.

[0090] S222, setting the front door model 22 to correspond to a plurality of front door degree of freedom feature points on the vehicle body model 1 one by one;

[0091] It can be understood that the front door model 22 corresponds one-to-one to the multiple front door degree of freedom feature points on the body model 1, so that the relative position of the front door model 22 and the body model 1 can be determined, thereby avoiding angle deviation or position deviation when the front door model 22 is installed on the body model 1, thereby causing deviation in the measurement of the gap value.

[0092] S223 , setting the front door deviation values ​​of the two front door degree of freedom feature points corresponding to the front door model 22 and the vehicle body model 1 .

[0093] It should be noted that the front door deviation value is the distance between the position of the front door degree of freedom feature point on the front door model 22 and the corresponding front door degree of freedom feature point on the body model 1. For example, when the front door deviation value is set to 0, it indicates that the corresponding two front door degree of freedom feature points overlap with each other, that is, the front door model 22 abuts against the body model 1.

[0094] In the technical solution of the present embodiment, it is first necessary to obtain a plurality of degree-of-freedom feature points on the front door model 22 and the vehicle body model 1, and the plurality of degree-of-freedom feature points on the front door model 22 are arranged in one-to-one correspondence with the plurality of degree-of-freedom feature points on the vehicle body model 1 to determine the relative position and relative angle of the connection between the front door model 22 and the vehicle body model 1, and then set the front door deviation value of the two corresponding degree-of-freedom feature points on the front door model 22 and the vehicle body model 1 to determine the posture of the front door model 22 installed on the vehicle body model 1, which is the posture of the front door actually installed on the vehicle body, so as to ensure the accuracy of the determination of the door hinge posture.

[0095] Furthermore, in the invention, there is no restriction on the specific number of the front door freedom feature points. It should be noted that, among the multiple front door freedom feature points, it is only necessary to ensure that each of the front door freedom feature points corresponds to restricting the movement or rotation of the front door in one direction.

[0096] At this time, the front door deviation value is the distance between the corresponding two degree-of-freedom feature points in the restricted activity direction.

[0097] Specifically, in this embodiment, the number of the front door degree of freedom feature points is set to 6, and the 6 front door degree of freedom feature points respectively restrict the movement or rotation of the front door model 22 in various directions. That is, among the 6 front door degree of freedom feature points, three of the front door degree of freedom feature points respectively restrict the movement of the front door model 22 along the X direction, Y direction, and Z direction of the body model 1; the other three front door degree of freedom feature points respectively restrict the rotation of the front door model 22 around the axis extending in the X direction, Y direction, and Z direction of the body model 1.

[0098] Please refer to the attached Figure 6 In this embodiment, A1, A2, A3, B1, B2, and C are all the front door degree of freedom feature points. The front door degree of freedom feature points A1, A2, and A3 on the front door model 22 correspond one-to-one to the front door degree of freedom feature points A1, A2, and A3 on the body model 1, so as to limit the movement of the front door model 22 along the Y direction of the body model 1 and the rotation of the axis extending along the X direction and the Z direction of the body model 1; the front door degree of freedom feature points B1 and B2 on the front door model 22 correspond one-to-one to the front door degree of freedom feature points B1 and B2 on the body model 1, so as to limit the movement of the front door model 22 along the X direction of the body model 1 and the rotation of the front door model 22 around the axis extending in the Z direction of the body model 1; the front door degree of freedom feature point C on the front door model 22 corresponds to the front door degree of freedom feature point C on the body model 1, so as to limit the movement of the front door model 22 along the Z direction of the body model 1.

[0099] The present invention also proposes a car, which includes a body and a door. The posture of the door installed on the body is based on the above-mentioned method for determining the door hinge posture. The specific structure of the method for determining the door hinge posture refers to the above-mentioned embodiment.
