Panoramic backdrop automobile roof rear assembly

Abstract

The invention discloses a brand-new panoramic backdrop automobile roof rear assembly structure which comprises a rear cross beam lower plate, a rear cross beam upper plate and a rear cross beam outerplate. The rear cross beam lower plate is concave, the rear cross beam upper plate is step-shaped, a first cavity is formed between the rear cross beam lower plate and the rear cross beam upper plate,and a second cavity is formed between the rear cross beam outer plate and the rear cross beam upper plate; and a backdrop glass fixing structure is arranged on the top surface of the rear cross beamouter plate. According to the scheme, the rear assembly structure is used for installing film-coated panoramic backdrop tempered glass, parts such as sunshade curtains, stiffening beams and ceilings can be omitted, the weight of an automobile body is reduced, the rigidity of an automobile roof is improved, the concave resistance of a top cover is improved, the space in the automobile is larger, transparent, open and bright, the view field is wide, lighting is good, and the ergonomics is improved.

Description

technical field [0001] The invention belongs to the technical field of vehicle body structures, and more specifically relates to a rear assembly of a roof cover of a panoramic canopy. Background technique [0002] At present, cars on the market can be divided into two types: those with sunroofs and those without sunroofs. The models without sunroofs are not transparent enough, the lighting and vision in the rear row are not good, and the enveloping space for the heads of drivers and passengers is small. , poor man-machine performance. Models with a sunroof structure are relatively expensive, and the traditional sunroof is limited by the structure, the opening area of ​​the sunroof is small, and the lighting effect is not ideal. In addition, the development cycle of models with a sunroof structure is longer. The traditional car roof is a sheet metal part with a large area, thinner material thickness and flatness, poor dent resistance, modal and stiffness performance, easy to...

[0002] At present, cars on the market can be divided into two types: those with sunroofs and those without sunroofs. The models without sunroofs are not transparent enough, the lighting and vision in the rear row are not good, and the enveloping space for the heads of drivers and passengers is small. , less man-machine

Models with a sunroof structure are relatively expensive and costly, and the traditional sunroof is limited by the structure, the opening area of ​​the sunroof is small, and the lighting effect is not ideal. In addition, the development cycle of models with a sunroof structure is longer

The traditional car roof is a sheet metal part with a large area, thinner and flat material, poor dent resistance, modal and stiffness performance, easy to collapse in the middle area, and difficult to control the dimensional accuracy
