Front cross beam for panoramic backdrop automobile roof

Abstract

The invention discloses a front cross beam for a panoramic backdrop automobile roof. The front cross beam comprises a front cross beam lower plate which is groove-shaped and comprises a bottom plate and side plates connected with the front end and the rear end of the bottom plate, and turnups are arranged at the tops of the side plates and are turned over towards one sides, far away from the bottom plate, of the side plates; a front cross beam upper plate covers the front cross beam lower plate, and the turnups of the front cross beam lower plate are connected with the bottom surface of the front cross beam upper plate, so that a cavity is formed between the front cross beam upper plate and the front cross beam lower plate; and a front windshield glass mounting surface and a canopy glass mounting surface are arranged on the top surface of the front cross beam upper plate. According to the scheme, the front cross beam is used for installing panoramic backdrop tempered glass, parts suchas a stiffening beam and a ceiling can be omitted, the weight of an automobile body is reduced, the rigidity of the automobile roof is improved, the concave resistance of the roof is improved, the space in the automobile is larger, transparent 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 front beam used for a roof of a car with a panoramic sun curtain. 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 are not good, the enveloping space for the heads of drivers and passengers is small, and the man-machine Engineering is poor. Models with a sunroof structure are expensive and relatively expensive, and traditional skylights are limited by their structure, with a small opening area and unsatisfactory lighting effects. In addition, models with a sunroof structure have a long development cycle. 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 collap...

[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, and the lighting and vision are not good. poor engineering

Models with a sunroof structure are expensive and relatively expensive, and traditional skylights are limited by their structure, with a small opening area and unsatisfactory lighting effects. In addition, models with a skylight structure have a long development cycle

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
