[0036] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings.

[0037] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in one or more embodiments of this specification should be understood by people with ordinary skills in the field to which this disclosure belongs. The "first", "second" and similar words used in one or more embodiments of this specification do not indicate any order, quantity or importance, but are only used to distinguish different components.

When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0038] To facilitate understanding of the verification method for frameless doors provided in the embodiment of the present application, its application scenario is first described. The verification method for frameless doors provided in the embodiment of the present application is applied in the automobile production process to verify whether the window glass of the frameless doors is qualified during assembly. When the window glass of current frameless doors is designed and produced, when the door is closed, interference between the window glass and the pillar is very likely to occur, resulting in unqualified final assembly. To this end, the embodiment of the present application provides a verification method for frameless doors to improve the assembly qualification rate of the window glass of frameless doors during the production process. It is described in detail below in conjunction with specific drawings and embodiments.

[0039] To facilitate understanding of the method provided by the embodiment of the present application, the application scenario of the car door is first introduced. When the car door is in use, it is assembled on the car body and rotates with the car body. When the car door is open, the user can get on and off the car. When the car door is closed, the car door is locked with the car body to protect the safety of the user when riding.

[0040] refer to Figure 1 and Figure 2 As shown, Figure 1 A schematic structural diagram of the cooperation between a vehicle door and a vehicle body provided in an embodiment of the present application is shown. Figure 2 The schematic diagram of the cooperation between the vehicle window glass and the sealing strip provided by the embodiment of the present application is shown. When the vehicle door 30 cooperates with the vehicle body, the vehicle door 30 is rotatably connected to the vehicle body through the vehicle door hinge 50, and the vehicle door hinge 50 is used to connect the vehicle door 30 to the vehicle body. When the vehicle door 30 is opened or closed, the vehicle door 30 is opened or closed by rotating the vehicle door hinge 50.

[0041] Since there is no structure to seal the window glass 40 at the top of the frameless door, the window glass 40 needs to abut against the sealing strip 60 assembled on the top sheet metal 10 of the vehicle body to achieve a sealing effect. When the window glass 40 is raised or lowered, it needs to be driven by a lifter disposed in the door 30. The lifter is hinged to the door 30 so that the lifter can rotate along an axis parallel to the length direction of the car, thereby driving the window glass 40 to have a certain swing amplitude in the width direction of the vehicle body. When the window glass 40 is raised or lowered, the lifter first drives the window glass 40 to rise, and then the window glass 40 abuts against the sealing strip 60 of the top sheet metal 10. Under the elastic action of the sealing strip 60, the window glass 40 is pushed to rotate a certain angle. The rotation angle of the window glass 40 driven by the sealing strip 60 is defined as the pre-bending amount. As Figure 2 As shown in Figure 2 2 exemplifies the theoretical position L1 of the window glass 40 before it rotates when it rises to cooperate with the sealing strip 60 on the top of the vehicle body, and the actual position L2 to which it rotates under the push of the sealing strip 60 .

[0042] When the vehicle door 30 is opened, in order to avoid interference between the vehicle window glass 40 and the sealing strip 60, the vehicle window glass 40 will drop a certain distance, and the dropped distance is defined as the drop amount of the vehicle window glass 40. For the convenience of description, the height position when the vehicle window glass 40 abuts against the sealing strip 60 is defined as the first position; the height position to which the vehicle window glass 40 drops to avoid interference with the sealing strip 60 is defined as the second position. When the vehicle door 30 is rotated from the open position to the closed position, if the vehicle window glass 40 is raised, it stops when it is raised to the second position. After the vehicle door 30 is closed, the central control of the car obtains the signal that the vehicle door 30 is closed and locked, and then controls the lifter to drive the vehicle window glass 40 to rise to the first position. Figure 2 As shown in Figure 2 The position L3 when the window glass 40 is lowered to the second position is exemplified in the figure. The above-mentioned lowering amount can be determined during the vehicle design process, and the set lowering amount only needs to satisfy that the window glass 40 will not interfere with the sealing strip 60 when the door 30 is opened.

[0043] However, when the door 30 is assembled, it is very easy to cause the window glass 40 to hit the pillar 20 when the door 30 is closed. For this reason, the embodiment of the present application provides a method for checking the window glass 40 of a frameless door 30, so as to reduce the interference between the window glass 40 and the pillar 20 after the door 30 is assembled. The checking method provided by the embodiment of the present application is described in detail below with reference to specific drawings.

[0044] refer to Figure 3 As shown, Figure 3 A flow chart of a method for verifying the window glass 40 of a frameless door 30 provided in an embodiment of the present application is shown. The verification method provided in an embodiment of the present application includes the following steps:

[0045] Step 001: Obtaining a static spacing set between the window glass 40 of the door 30 and the pillar 20;

[0046] Specifically, when designing a vehicle, the static spacing between the window glass 40 and the pillar 20 is a technical parameter set in advance. Therefore, after the vehicle design is completed, the static spacing is a known value. The above-mentioned static spacing refers to the spacing between the window glass 40 of the door 30 and the pillar 20 after the door 30 is closed and locked. In the embodiment of the present application, the door 30 may be the door 30 corresponding to the front seat of the car, in which case the pillar 20 is the B-pillar; of course, the door 30 may also be the door 30 corresponding to the rear seat of the car, in which case the pillar 20 is the C-pillar. For the convenience of description, in the embodiment of the present application, the door 30 is the door 30 corresponding to the front seat of the car, and the pillar 20 is the B-pillar.

[0047] However, when the pillar 20 is assembled, the assembly of the pillar 20 can be deemed qualified within the set tolerance range. Therefore, the set static spacing between the window glass 40 and the pillar 20 also fluctuates within a certain range. Exemplarily, the position of the pillar 20 is X±B, X is the set static spacing, and B is the tolerance value. When the pillar 20 is assembled to meet its tolerance requirements but the pillar 20 is close to the window glass 40, the static spacing between the window glass 40 and the pillar 20 is small. When the door 30 is closed, the window glass 40 is very likely to interfere with the pillar 20. Therefore, in the embodiment of the present application, according to the assembly position of the pillar 20 and the set tolerance, the minimum static spacing between the door 30 and the pillar 20 is determined as the set static gap. Therefore, the interference between the window glass 40 and the pillar 20 can be detected from the extreme position.

[0048] When the window glass 40 is matched with the door 30 , if the vehicle pillar 20 does not interfere with the window glass 40 at the extreme position, then no interference will occur at other positions of the vehicle pillar 20 , thereby ensuring the reliability of detection.

[0049] Step 002: Determine the theoretical position of the door hinge 50 according to the set static spacing;

[0050] Specifically, in the embodiment of the present application, the position of the pillar 20 is used as a reference position, and after knowing the size of the set static gap, the theoretical position of the door hinge 50 can be determined. In the embodiment of the present application, the above-mentioned theoretical position refers to the position of the axis around which the door 30 rotates when the door 30 is designed. After the position of the pillar 20 and the set static gap are determined, the theoretical position of the door hinge 50 can be determined.

[0051] Step 003: determining a plurality of maximum offset positions of the door hinge 50 for assembly according to the theoretical position and tolerance of the door hinge 50;

[0052] Specifically, when the door 30 is assembled, it also fluctuates within a certain tolerance range, that is, when the door 30 is assembled, the door hinge 50 also fluctuates within a certain tolerance range. When the door hinge 50 is in different positions, the distance between the corresponding window glass 40 and the pillar 20 will also change.

[0053] For example, the maximum offset of the door hinge 50 in the length direction of the vehicle body and the maximum offset of the door hinge 50 in the width direction of the vehicle body are determined according to the tolerance, and the four maximum offset positions of the door hinge 50 are determined according to the maximum offset of the door hinge 50 in the length direction and the width direction of the vehicle body. In the embodiment of the present application, the door hinge 50 may have a certain tolerance in both the width direction and the length direction of the vehicle. Therefore, within the range allowed by its tolerance, the door hinge 50 has four maximum offset positions, such as Figure 4As shown in Figure 4 A1 is the theoretical position of the door hinge 50, and A2, A3, A4 and A5 are the maximum offset positions of the door hinge 50 in the length direction and the width direction of the vehicle, respectively. The above-mentioned A2, A3, A4 and A5 form a rectangle with A1 as the center.

[0054] In an practicable solution, the maximum offset of the door hinge 50 in the length direction of the vehicle body and the maximum offset of the door hinge 50 in the width direction of the vehicle body are both ±2.5mm. That is, the tolerance range of the door hinge 50 is ±2.5mm, and A2, A3, A4 and A5 form a square with A1 as the center. It should be understood that the above-mentioned maximum offset can also be selected from other values ​​as needed, such as ±2mm, ±2.2mm, ±2.5mm, ±2.7mm, ±3mm and other different values.

[0055] Step 004: according to a plurality of maximum offset positions of the vehicle door 30, obtaining a movement trajectory of the vehicle window glass 40 on the vehicle door 30 during the closing process of the vehicle door 30 at each maximum offset position;

[0056] Specifically, the above-mentioned motion trajectory refers to the motion trajectory formed by the window glass 40 when the vehicle door 30 rotates around the door hinge 50 .

[0057] In specific implementation, the drop amount of the door 30 can be obtained first, and the drop amount is the drop amount of the window glass 40 set to avoid the body sealing strip 60 when the door 30 is opened. After the position of the door hinge 50 is determined, after the drop amount of the window glass 40 is known, the position of the window glass 40 can be calculated. The height position of the window glass 40 is the second position mentioned above. It can be seen from the above description that during the closing process of the door 30, the height position of the window glass 40 is at the second position. Therefore, by obtaining the motion trajectory of the window glass 40 at the second position as a parameter for subsequent judgment, the detection effect of the window glass 40 of the door 30 can be better improved.

[0058] Therefore, the height of the window glass 40 during the closing process of the door 30 can be determined according to the falling amount of the window glass 40; the movement trajectory of the window glass 40 can be determined according to the height of the window glass 40 and each maximum offset position of the door 30. During the closing process of the door 30, the window glass 40 rotates away from the axis of the door hinge 50, thereby forming an arc-shaped trajectory. The interference between the window glass 40 and the pillar 20 involved in the embodiment of the present application can be judged by whether the window glass 40 and the pillar 20 have interference during the closing process of the door 30.

[0059] In an practicable solution, the step of determining the motion trajectory of the window glass 40 according to the height of the window glass 40 and each maximum offset position of the door 30 is specifically: determining the motion trajectory of the window glass 40 according to the height of the corner of the window glass 40 away from the door hinge 50 and each maximum offset position of the door 30. Figure 1 It can be seen that the edge of the window glass 40 away from the pillar 20 is an inclined edge, and the top corner of the edge is closest to the position of the pillar 20. Therefore, by judging the movement trajectory of the corner and the situation between the pillar 20, the situation between the window glass 40 and the pillar 20 can be judged.

[0060] The above-mentioned corner of the vehicle window glass 40 can be understood as a position of the vehicle window glass 40 farthest from the vehicle door hinge 50 along the vehicle body direction. Its corresponding height can be determined by the drop amount of the vehicle window glass 40, which will not be described in detail here.

[0061] Step 005: measuring the minimum movement gap between each movement trajectory and the vehicle column 20;

[0062] In specific measurements, when the door hinge 50 is in different positions, such as the above-mentioned positions A2, A3, A4 and A5, four different motion trajectories are generated. The gaps between the four motion trajectories and the pillar 20 are different, and the gaps are defined as motion gaps. There is a minimum motion gap between each motion gap and the pillar 20, that is, the distance at which the window glass 40 is closest to the pillar 20 during the rotation of the window glass 40.

[0063] Exemplarily, when the door hinge 50 is located at position A2, the corresponding motion trajectory is B1, and the minimum motion gap between the motion trajectory B1 and the window glass 40 is C1; when the door hinge 50 is located at position A3, the corresponding motion trajectory is B2, and the minimum motion gap between the motion trajectory B2 and the window glass 40 is C2; when the door hinge 50 is located at position A4, the corresponding motion trajectory is B3, and the minimum motion gap between the motion trajectory B3 and the window glass 40 is C3; when the door hinge 50 is located at position A5, the corresponding motion trajectory is B4, and the minimum motion gap between the motion trajectory B4 and the window glass 40 is C4.

[0064] When the minimum movement gap is used for judgment, if the minimum movement gap can ensure that there is no interference between the window glass 40 and the pillar 20 , then other movement gaps can also ensure that there is no interference between the window glass 40 and the pillar 20 .

[0065] When obtaining the clearance, the minimum clearance at the same height of each motion trajectory and the corner of the vehicle window glass 40 is obtained. Similarly, since the corner of the vehicle window glass 40 is closest to the vehicle pillar 20, the motion trajectory of the corner of the vehicle window glass 40 is used as a judgment parameter. If the clearance between the motion trajectory of the vehicle window glass 40 and the vehicle pillar 20 meets the requirement, the clearances at other positions of the vehicle window glass 40 can meet the requirement.

[0066] Step 006: Compare any minimum movement gap with the set movement gap. If any minimum movement gap is smaller than the set movement gap, it is confirmed that the assembly of the vehicle door 30 is unqualified; if any minimum movement gap is greater than or equal to the set movement gap, it is confirmed that the assembly of the vehicle door 30 is qualified.

[0067] Specifically, when making a judgment, by comparing the minimum motion gap with the set motion gap, it is possible to judge whether the assembly of the door 30 is appropriate based on the comparison result. Exemplarily, if the set motion gap is C, then when C1, C2, C3 and C4 are all ≥ C, it is determined that during the closing process of the door 30, interference will occur between the window glass 40 and the pillar 20, and the assembly of the door 30 is qualified. If any one of C1, C2, C3 and C4 is less than C, it is determined that during the closing process of the door 30, interference will occur between the window glass 40 and the pillar 20, and the assembly of the door 30 is unqualified. If C1<C or C2<C, it can be determined that interference will occur between the window glass 40 and the pillar 20, and the assembly of the door 30 is unqualified.

[0068] In an implementable solution, the set movement gap is between 0.3 mm and 0.5 mm, such as different distances such as 0.3 mm, 0.4 mm, and 0.5 mm.

[0069] It can be seen from the above description that by collecting the movement trajectory of the window glass 40 rotating when the door 30 is in various positions that meet the assembly tolerance position of the door hinge 50, and judging the minimum movement gap between the movement trajectory and the vehicle pillar 20, and based on the comparison result of the minimum movement gap when the door hinge 50 is in various positions with the set movement gap, it is determined whether the window glass 40 of the door 30 is qualified.

[0070] The verification method provided in the embodiment of the present application also includes adjusting at least one of the following conditions if any minimum movement gap is less than the set movement gap: 1) adjusting the theoretical position of the door hinge 50, 2) adjusting the pre-bending amount of the window glass 40, 3) adjusting the curvature of the window glass 40, 4) adjusting the short drop amount of the window glass 40.

[0071] Only one of the above conditions can be adjusted, or at least two of them can be adjusted, so as to ensure that there is no interference between the window glass 40 and the pillar 20 during the closing process of the door 30. In specific adjustments, such as adjusting the theoretical position of the door hinge 50, the adjustment can be made by adjusting the set static spacing between the window glass 40 and the pillar 20, such as increasing the set static spacing, thereby increasing the distance between the window glass 40 and the pillar 20 in the length direction of the vehicle body, so as to ensure that there is no interference between the window glass 40 and the pillar 20 during the closing process of the door 30. For example, when adjusting the pre-bending amount of the window glass 40, the distance between the window glass 40 and the pillar 20 in the width direction of the vehicle body can be increased. For example, when adjusting the curvature of the window glass 40, the curvature of the window glass 40 can be reduced to increase the distance between the window glass 40 and the pillar 20 in the width direction of the vehicle body. When adjusting the short drop amount of the window glass 40, the height of the window glass 40 can be reduced to increase the distance between the window glass 40 and the pillar 20 in the length direction of the vehicle body. In the above-mentioned different adjustment methods, the interference between the window glass 40 and the pillar 20 can be improved by a single adjustment, or multiple adjustment conditions can be used to adjust simultaneously to improve the interference between the window glass 40 and the pillar 20.
