An installation and reinforcement structure for a large outward-opening skylight and its welding method

Abstract

This solution provides a large sunroof installation reinforcement structure, including a basic frame composed of a front beam connecting plate, a rear reinforcement beam structure, two side reinforcements, and an outer panel of the top cover. The above split structures are combined into a rectangular shape. The closed-loop structure contributes to the overall rigidity, and also facilitates the reliability of the automatic replacement of parts on the production line, and overcomes the problem of inconvenient installation and positioning caused by the large-sized outward-opening skylight structure due to its large size and heavy weight. Positioning holes are provided on the crossbeam connecting plate, rear reinforcement crossbeam structure, side reinforcements and the outer panel of the top cover, which helps to improve the installation position accuracy of the large sunroof on the vehicle. This solution also provides a welding method for installing the reinforcement structure using the above-mentioned large outward-opening skylight.

Description

technical field [0001] The invention relates to the technical field of automobile sheet metal parts, in particular to a mounting reinforcement structure for a large sunroof that opens outwards and a welding method thereof. Background technique [0002] With the upgrading of automobile consumption, consumers have more and more diversified demands on vehicles, and the configuration of complete vehicles is also constantly enriched. The vehicle is equipped with a sunroof, which helps to improve the quality of the entire vehicle, thereby enhancing the competitiveness of the entire vehicle. [0003] At present, the vast majority of models use built-in sunroofs, and very few models use large sunroofs that open outwards. First of all, the front part of the exterior structure is no longer designed with a complete top cover outer panel. Secondly, the increase in the size of the sunroof leads to an increase in the front opening of the entire top cover assembly. As a result, the defe...
