Description

Technical Field

[0001] This invention belongs to the field of vehicle door mounting structure technology, specifically relating to a vehicle door mounting structure and a vehicle door assembly method. Background Technology

[0002] Car doors are one of the main components of a vehicle. On one hand, they provide access for the driver and passengers, and isolate the vehicle from external interference. On the other hand, they mitigate side impacts, providing protection.

However, gull-wing doors consist of two main parts: a top wing and side wings. Their structure is more complex than ordinary doors, and they require ensuring the precision of the internal assembly between the top and side wings, as well as the precision of the assembly between the gull-wing door system and the vehicle body. Currently, during door installation, poor sealing between various components, uneven surface finishes between the door and surrounding parts, and poor visual perception are common problems.

[0049] The present invention provides a door mounting structure comprising a first tooling, a second tooling, a third tooling, a fourth tooling, and a fifth tooling. The door mounting process using this door mounting structure is as follows: (1) First, the top wing is mounted on the first tooling, and then the main hinge is mounted on the first tooling. The top wing and the main hinge are assembled together using the first tooling. The bolts between the main hinge and the top wing are tightened. Finally, the first tooling is removed to form the top wing sub-assembly, ensuring the assembly accuracy between the main hinge and the top wing, good repeatability, and high assembly accuracy. (2) First, the second tooling is mounted on the roof crossbeam assembly and the side panel assembly. Then, the top wing sub-assembly is mounted on the second tooling. The top wing sub-assembly is assembled onto the roof crossbeam assembly using the second tooling. Finally, the second tooling is removed to ensure the assembly accuracy of the top wing sub-assembly and the roof crossbeam assembly around the perimeter. (3) First, install the third tooling on the top wing. Position the upper part of the side wing in the Y direction on the third tooling. Directly connect the side wing and the top wing in the Y direction through the third tooling to ensure the Y-direction sealing accuracy between the side wing and the top wing, resulting in high assembly accuracy. (4) First, install the fourth tooling on the side assembly, then install the side wing on the fourth tooling. Assemble the side wing onto the side assembly through the fourth tooling. Finally, remove the third and fourth toolings to ensure the matching accuracy of the appearance gap and surface difference between the side wing and the side assembly. (5) First, install the fifth tooling on the side assembly, then install the front door on the fifth tooling. Assemble the front door onto the side assembly through the fifth tooling (sharing the same main positioning hole as the fourth tooling). Finally, remove the fifth tooling to ensure the matching accuracy of the appearance gap and surface difference between the front door and the door assembly. Flatten the front door according to the rear Y-direction surface difference to complete the matching of the front door and the door. Thus, the entire door system assembly is completed. The third tooling is a contour tooling, which assembles the sealing gap between the side wing and the top wing to the theoretical design state.

[0050] In this example, the door installation structure uses five tooling fixtures—the first, second, third, fourth, and fifth—to assemble the sealing gap between the side wing and the top wing to the theoretical design state, ensuring the sealing accuracy inside the door system, preventing water leakage, and improving safety. The tooling directly assembles the top wing, side wing, and front door to the vehicle body, linking the top wing to the roof crossbeam assembly and the side wing to the side panel assembly. The dimensional links between the top / side wing and surrounding components are short, resulting in high assembly accuracy and good visual perception of gap surface differences after assembly. The tooling is simple, lightweight, and easy to operate, improving cycle time and ensuring good assembly consistency. Attached Figure Description

Specifically, there is one second X / Z-axis locating pin 22, three second Z-axis locating pins 23, two second Y-direction locating surfaces 24, one third X / Z-axis locating pin 25, one third Z-axis locating pin 26, and four third Y-direction locating surfaces 27, which can directly connect the top wing sub-assembly with the roof crossbeam assembly in the X / Y / Z directions, ensuring the assembly accuracy of the top wing sub-assembly relative to the roof crossbeam assembly. Tighten the mounting bolts of the main hinge 6 on the roof crossbeam assembly to solidify the relative position of the roof wing sub-assembly and the roof crossbeam assembly. At this point, the roof wing sub-assembly is assembled onto the vehicle body structure.

[0106] As an example, in step S3, refer to Figure 9First, the third tooling 3 is installed on the top wing 7, and the upper part of the side wing 8 is installed on the third tooling 3 in the Y direction. The side wing 8 and the top wing 7 are directly connected in the Y direction through the third tooling 3, which can ensure the sealing accuracy between the side wing 8 and the top wing 7 and the assembly accuracy is high. The second X / Y locating pin 32, the second Y locating pin 33 and the second Z locating surface 34 are used to connect the main body 31 of the third tooling and the top wing 7 in the X / Y direction; the fourth Y locating surface 35 is used to connect the side wing 8 and the main body 31 of the third tooling in the Y direction; thus ensuring the Y-direction assembly accuracy of the side wing 8 relative to the top wing 7. The third tooling 3 is a contouring tooling. The upper part of the side wing 8 is assembled onto the contouring tooling in the Y direction. The contouring tooling is then assembled onto the top wing 7. The side wing 8 is directly mounted on the fourth Y-direction positioning surface 35. The fourth Y-direction positioning surface 35 simulates the theoretical position of the side wing 8. The third tooling 3 directly connects the side wing 8 and the top wing 7 along the Y direction, ensuring the Y-direction sealing accuracy between the side wing 8 and the top wing 7. There are four second Z-direction positioning surfaces 34, one second X / Y-direction positioning pin 32, one second Y-direction positioning pin 33, and two fourth Y-direction positioning surfaces 35. These directly connect the side wing 8 and the top wing 7 in the X / Y / Z directions, ensuring the assembly accuracy of the side wing 8 relative to the top wing 7. Tighten the mounting bolts on the secondary hinge connecting the top wing 7 and the side wing 8 to solidify the relative position of the side wing 8 and the body-in-white. At this point, the side wing 8 is assembled onto the body.

[0107] As an example, in step S4, refer to Figure 9First, install the fourth tooling 4 on the side assembly, then install the side wing 8 on the fourth tooling 4, and assemble the side wing 8 onto the side assembly using the fourth tooling 4. Finally, remove the third tooling 3 and the fourth tooling 4 to ensure the matching accuracy of the appearance gap and surface difference between the side wing 8 and the side assembly. The fourth X / Z locating pin 42, the fourth Z locating pin 43, and the fifth Y locating surface 44 are used to connect the fourth tooling body 41 with the side assembly along the X / Y direction. The fifth Y locating surface 44 ensures the Y-direction assembly accuracy between the fourth tooling 4 and the side assembly. The fourth X / Z locating pin 42 and the fourth Z locating pin 43 ensure the X / Y-direction assembly accuracy between the fourth tooling 4 and the side assembly. The fifth X / Z locating pin 45, the fifth Z locating pin 46, and the sixth Y locating surface 47 are used to connect the side wing 8 with the fourth tooling body 41 along the X / Z direction. The sixth Y locating surface 47 ensures the Y-direction assembly accuracy between the side wing 8 and the fourth tooling 4. The fifth X / Z locating pin 45 and the fifth Z locating pin 46 ensure the X / Z-direction assembly accuracy between the side wing 8 and the fourth tooling 4. Among them, there are four fifth Y-axis positioning surfaces 44, one fourth X / Z-axis positioning pin 42, one fourth Z-axis positioning pin 43, four sixth Y-axis positioning surfaces 47, one fifth X / Z-axis positioning pin 45, and one fifth Z-axis positioning pin 46. These components can directly connect the side wing 8 and the side wall assembly in the X / Y / Z directions, ensuring the assembly accuracy of the side wing 8 relative to the side wall assembly. The X-axis assembly accuracy is used to ensure the clearance requirements between the side wing 8 and the side wall assembly, the Y-axis assembly accuracy is used to ensure the surface difference requirements between the side wing 8 and the side wall assembly, and the Z-axis assembly accuracy is used to ensure the alignment requirements during installation of the side wing 8 and the side wall assembly.

[0108] As an example, in step S5, refer to Figure 10First, the fifth tooling 5 is installed on the side assembly (sharing the same main positioning hole as the fourth tooling). Then, the front door 9 is installed on the fifth tooling 5. The front door 9 is then assembled onto the side assembly using the fifth tooling 5. Finally, the fifth tooling 5 is removed. This ensures the matching accuracy of the appearance gap and surface difference between the door assembly and the side assembly. Based on the rear Y-direction surface difference, the front door 9 is flattened, completing the matching of the front door 9 and the door. At this point, the entire door system assembly is complete. The seventh X / Z-direction positioning pin 55, the seventh Z-direction positioning pin 56, and the eighth Y-direction positioning surface 57 are used to connect the front door 9 and the main body 51 of the fifth tooling along the X / Z direction. The eighth Y-direction positioning surface 57 ensures the Y-direction assembly accuracy between the front door 9 and the fifth tooling 5, while the seventh X / Z-direction positioning pin 55 and the seventh Z-direction positioning pin 56 ensure the X / Z-direction assembly accuracy between the front door 9 and the fifth tooling 5. The system includes four seventh Y-axis positioning surfaces 54, one sixth X / Z-axis positioning pin 52, one sixth Z-axis positioning pin 53, four eighth Y-axis positioning surfaces 57, one seventh X / Z-axis positioning pin 55, and one seventh Z-axis positioning pin 56. These components directly connect the front door 9 and the side panel assembly in the X / Y / Z directions, ensuring the assembly accuracy of the front door 9 relative to the side panel assembly. X-axis accuracy ensures the clearance requirements between the front door 9 and the side panel assembly; Y-axis accuracy ensures the surface difference requirements between the front door 9 and the side panel assembly; and Z-axis accuracy ensures the alignment requirements between the front door 9 and the side panel assembly during installation.
