Description

Technical Field

[0001] The present invention belongs to the technical field of door installation structures, and particularly relates to a door installation structure and a door assembly method. Background Art

[0002] The door is one of the main components of a vehicle. On the one hand, it can open and close the access passage for the driver and passengers and isolate external interference. On the other hand, the door can reduce side impacts and play a protective role. An ordinary door only has side wings, and the assembly of an ordinary door only needs to solve the assembly accuracy between the side wings and the vehicle body; while a gull-wing door consists of a top wing and two side wings, and its structure is more complex than that of an ordinary door. Moreover, for a gull-wing door, it is necessary to solve the assembly accuracy within the system between the top wing and the side wings, and also to solve the assembly accuracy between the gull-wing door system and the vehicle body. At present, when the door is installed, the sealing accuracy between various structures is poor, the matching clearance surface between the door and the surrounding environmental parts is not good, and the visual perception is poor.

Among them, there is one second X / Z-direction positioning pin 22, three second Z-direction positioning pins 23, two second Y-direction positioning surfaces 24, one third X / Z-direction positioning pin 25, one third Z-direction positioning pin 26, and four third Y-direction positioning surfaces 27, which can directly link the top wing sub-assembly with the roof crossbar assembly in the X / Y / Z direction, thereby ensuring the assembly accuracy of the top wing sub-assembly relative to the roof crossbar assembly.

The second X / Y direction positioning pin 32, the second Y direction positioning pin 33 and the second Z direction positioning surface 34 are used to connect the third tooling body 31 with the top wing 7 in the X / Y direction; the fourth Y direction positioning surface 35 is used to connect the side wing 8 with the third tooling body 31 in the Y direction; the Y direction assembly accuracy of the side wing 8 relative to the top wing 7 is ensured. The third tooling 3 is a profiling tooling, the upper part of the side wing 8 is assembled on the profiling tooling in the Y direction, the profiling tooling is assembled on 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, and the third tooling 3 directly associates the side wing 8 with the top wing 7 in the Y direction to ensure the Y-direction sealing accuracy between the side wing 8 and the top wing 7. Among them, 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, which can directly associate the side wing 8 with the top wing 7 in the X / Y / Z direction to ensure 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, and the side wing 8 is assembled to the body.

The fourth X / Z-direction positioning pin 42, the fourth Z-direction positioning pin 43 and the fifth Y-direction positioning surface 44 are used to make the fourth tooling main body 41 contact with the side wall assembly along the X / Y direction. The fifth Y-direction positioning surface 44 ensures the Y-direction assembly accuracy between the fourth tooling 4 and the side wall assembly. The fourth X / Z-direction positioning pin 42 and the fourth Z-direction positioning pin 43 ensure the X / Y-direction assembly accuracy between the fourth tooling 4 and the side wall assembly; the fifth X / Z-direction positioning pin 45, the fifth Z-direction positioning pin 46 and the sixth Y-direction positioning surface 47 are used to make the side wing 8 contact with the fourth tooling main body 41 along the X / Z direction; the sixth Y-direction positioning surface 47 ensures the Y-direction assembly accuracy between the side wing 8 and the fourth tooling 4, and the fifth X / Z-direction positioning pin 45 and the fifth Z-direction positioning pin 46 ensure the X / Z-direction assembly accuracy between the side wing 8 and the fourth tooling 4.

The X-direction assembly accuracy is used to ensure the gap requirement between the side wing 8 and the side wall assembly, the Y-direction assembly accuracy is used to ensure the surface difference requirement between the side wing 8 and the side wall assembly, and the Z-direction assembly accuracy is used to ensure the alignment requirement when the side wing 8 and the side wall assembly are installed.

[0108] As an example, in step S5, refer to Figure 10, first install the fifth fixture 5 on the side panel assembly (sharing the same main positioning hole with the fourth fixture), then install the front door 9 on the fifth fixture 5, assemble the front door 9 to the side panel assembly through the fifth fixture 5, and finally remove the fifth fixture 5, which can ensure the appearance gap and surface difference matching accuracy between the door assembly and the side panel assembly, and suck the front door 9 flat according to the Y-direction surface difference at the back to complete the matching of the front door 9 and the door. At this point, the entire door system is assembled. 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 with the fifth fixture body 51 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 fixture 5, and 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 fixture 5. Among them, there are four seventh Y-direction positioning surfaces 54, one sixth X / Z-direction positioning pin 52, one sixth Z-direction positioning pin 53, four eighth Y-direction positioning surfaces 57, one seventh X / Z-direction positioning pin 55, and one seventh Z-direction positioning pin 56, which can directly associate the front door 9 with the side panel assembly in the X / Y / Z directions, thereby ensuring the assembly accuracy of the front door 9 relative to the side panel assembly. The X-direction accuracy is used to ensure the clearance requirement between the front door 9 and the side panel assembly, the Y-direction accuracy is used to ensure the surface difference requirement between the front door 9 and the side panel assembly, and the Z-direction accuracy is used to ensure the alignment requirement between the front door 9 and the side panel assembly during installation.
