Embodiment Construction
[0033] Combine below figure 1 and figure 2 , the present invention is further described:
[0034] Such as figure 1 as shown, figure 1 The middle dotted line area is the rear door lock area of the automobile side wall outer panel involved in the present invention. Among them, the Z-axis is from the roof to the bottom of the car, the X-axis is from the front to the rear of the car, and the Y-axis is from the left door to the right door of the car.
[0035] figure 2 is according to figure 1 A-A sectional view of the middle dotted line area, which firstly requires the structural design of the parts in the rear door lock area of the side wall outer panel. Considering the appearance matching requirements of the rear door outer panel and the side wall outer panel, the outer feature fillet of the side wall outer panel should be designed reasonably, and the outer feature fillet radius R1 is too large, which will affect the appearance matching of the rear door outer panel an...

The invention relates to a regional structure of a rear door lock for an automotive side outer plate and a design method thereof, which comprises a side wall door opening sealing surface, a side wall door opening welding edge and a side outer plate parting line stop edge, wherein the side wall door opening welding edge is connected with the side outer plate parting line stop edge through the side wall door opening sealing surface; and the upper part of the side wall door opening sealing surface (A) is in transition with the stop edge of a side outer plate parting line (C) through an external characteristic fillet, and the lower part of the side wall door opening sealing surface (A) is in transition with the side wall door opening welding edge (B) through a fillet at the lower part of the door lock. The regional structure of the rear door lock is characterized in that a first step (T1) is additionally arranged between the side outer plate parting line (C) and the side wall door opening sealing surface (A) and satisfies the requirements of a punched and drawn addendum to prevent the side outer plate from being drawn and cracked; a second step (T2) is also additionally arranged on the side door opening welding edge (B); and through the second step (T2), the part strength is enhanced, and the dimensional stability of the welding edge is improved.
Description
technical field [0001] The invention relates to the design field of automobile body-in-white parts, in particular to a rear door lock area structure of an automobile side wall outer panel and a design method thereof. Background technique [0002] A new car costs a lot of money from initial market research to mass production. The cost and time of body development and design account for about 70% of the cost and time of vehicle development. The side wall outer panel is the core of the body-in-white parts manufacturing. It has the characteristics of complex shape, large structural size, difficult forming, and high quality requirements for the outer surface. In the development process of vehicle body parts, the side panel takes a long time and costs a lot. There are many overlapping parts around the outer panel of the side wall, and the quality of the finished product will directly affect the assembly and appearance clearance requirements of the vehicle. [0003] By investiga...
