Double-ring type reinforcing structure of rear air window

Abstract

The invention discloses a double-ring type reinforcing structure of a rear air window. The structure comprises a top cover supporting beam assembly, a vehicle body D column and a vehicle body lower framework, the top cover supporting beam assembly located at the tail portion of a vehicle, the vehicle body D column and the vehicle body lower framework located at the tail portion of the vehicle are fixed to form a first longitudinal annular structure, a second longitudinal annular structure is fixed to the first longitudinal annular structure, and rear windshield glass is bonded and fixed to the second longitudinal annular structure. According to the invention, the combination of the two longitudinal annular structures is adopted, a traditional installation structure of rear air window assembly glass and sheet metal parts is replaced, the visual area of a rear air window is greatly increased, and the viewing experience of passengers is improved. The peripheral structure of the rear air window is constructed by adopting section bars, so that the cost of stamping part dies is reduced, and meanwhile, light weight is realized.

Description

technical field [0001] The invention relates to the technical field of vehicle body structures, in particular to a double-ring reinforcement structure for a rear windshield. Background technique [0002] With the rapid development of artificial intelligence technology and network technology and the rapid growth of labor costs, more and more companies have begun to apply unmanned driving technology to cars, especially for park cars and shuttle cars, which have a single operating environment and transport The development of unmanned buses has always been the direction of development for vehicles with a large number of people and high comfort requirements. In order to meet the requirements of long running time, more members in a single transport, passengers have higher requirements for comfort, and a larger field of vision in the car, the unmanned bus needs to have a longer cruising range and vehicle comfort. At the same time, there are larger windshields for passengers to enj...

AI Technical Summary

Problems solved by technology

Since there is no need for an open area for the rear windshield of the bus, the cost and weight of the vehicle body can be greatly reduced if the rear door is cancelled, but the cancellation of the rear door means that the cavity formed by the inner and outer panels of the rear door is gone, and the wind The rigidity of the window will also decrease accordingly.
