Problems solved by technology

[0002] In recent years, panoramic sunroofs have become more and more popular on SUV models. However, in the process of vehicle development, if large-sized panoramic sunroofs are arranged, it will inevitably lead to problems such as inconvenient arrangement of shark fin antenna harnesses and difficulties in bolt installation. To solve the above In order to facilitate the installation of shark fin antennas, methods such as reducing the section of the rear beam or canceling the structure of the rear beam are generally used in the prior art
[0003] In actual vehicle design, the method of canceling the rear beam of the roof will directly cause a significant decrease in the strength of the roof, and it is not suitable to adopt
As for the method of reducing the cross-section of the rear beam, since the current method is simply to reduce the cross-sectional size of the rear beam, it will reduce the section coefficient of the rear beam, thereby reducing the compressive strength of the roof, and there are also problems that do not meet the compressive performance of the roof of related vehicles risks of

Embodiment 1

[0032] This embodiment relates to a cross-sectional structure of the rear beam of the roof, which consists of figure 1 and combine figure 2 As shown, the cross-sectional structure of the roof rear beam includes a rear beam upper plate 8 and a rear beam lower plate 9 whose two ends are fastened together and fastened together, wherein the rear beam lower plate 9 specifically includes top transverse plate bodies that are sequentially fixed 91, the vertical plate body 92, the bottom horizontal plate body 93 and the connecting plate body 94, the top horizontal plate body 91 and the connecting plate body 94 are respectively used to connect with the two ends of the rear beam upper plate 8, and the top horizontal plate body 91 is connected to the bottom The transverse plate bodies are arranged in parallel and also arranged along the length direction of the vehicle.

[0033] In addition, in this embodiment, the angle α between the vertical plate body 92 and the vehicle height directi...

Embodiment 2

[0050] This embodiment relates to a vehicle, the vehicle includes a car body with a roof, and a shark fin antenna is installed on the outer surface of the rear part of the roof, and corresponding to the shark fin antenna, a shark fin antenna is further provided on the inner surface of the roof The roof rear beam having the cross-sectional structure of the roof rear beam in the first embodiment.

[0051] The vehicle of this embodiment is provided with a roof rear beam having a cross-sectional structure as in Embodiment 1, which can facilitate the arrangement of the shark-fin antenna wiring harness, and also facilitate the installation of the shark-fin antenna mounting bolts, and has good practicability.

Abstract

The invention provides a vehicle roof rear cross beam section structure, a vehicle and an analysis method for improving a section coefficient of the vehicle roof rear cross beam section structure. Thevehicle roof rear cross beam section structure comprises a rear cross beam upper plate and a rear cross beam lower plate, of which two ends are fixedly connected and then buckled in one body; the rear cross beam lower plate comprises a top cross plate body, a vertical plate body, a bottom cross plate body and a connecting plate body which are fixedly connected in sequence, wherein the top cross plate body and the bottom cross plate body are arranged in the length direction of the vehicle, and a shark fin antenna wire harness arrangement groove located in the outer side of the vertical plate body is formed below the top cross plate body. According to the vehicle roof rear cross beam section structure, the shark fin antenna wire harness arrangement groove similar to a right angle is formedin the rear cross beam lower plate; therefore, the arrangement space can be provided for the shark fin antenna wire harness, the interference of the shark fin antenna wire harness on the installationof a shark fin antenna installation bolt can be avoided, the smooth installation of the shark fin antenna installation bolt can be facilitated, and the practicability of the structure is very good.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a cross-sectional structure of a roof rear beam.
