Automatic skylight device of automobile

Abstract

The invention provides an automatic skylight device of an automobile. The automatic skylight device of the automobile comprises skylight glass, a sliding module and a rotating module. The sliding module comprises four-bar linkage mechanisms and two sliding module stretching and retracting structures, wherein each four-bar linkage mechanism is formed by connecting a first rod piece, a second rod piece, a third rod piece and a fourth rod piece at vertexes in a rotating mode. The first rod pieces are fixedly connected to an automobile body. Each third rod piece comprises a skylight sliding chute with a mounting joint. One end of each sliding module stretching and retracting structure is connected with one corner, facing one side of the corresponding skylight sliding chute, of two corners of the skylight glass. The other end of each sliding module stretching and retracting structure is connected with the corresponding mounting joint. The sliding module further comprises internally hidden sliding chutes which are located on extension lines of the skylight sliding chutes inside a roof of the automobile. The rotating module comprises rotating blocks and two rotating module stretching and retracting structures, wherein the rotating blocks are fixedly connected to the second rod pieces. One end of each rotating module stretching and retracting structure is connected with one of two ends of the corresponding rotating block. The other end of each rotating module stretching and retracting structure is fixedly connected with the automobile body. Through the automatic skylight device of the automobile, external opening and internal hiding of the automobile skylight are combined, a transmission mechanism is simplified, the environment in the automobile is improved, and the grade of the automobile is promoted.

Description

technical field [0001] The invention belongs to the technical field of automobile bodies, and relates to an automatic sunroof device for automobiles. Background technique [0002] The temperature and air quality in the car have a great influence on the comfort of the drivers and passengers. The automatic sunroof of the car is a high-tech product integrating advanced materials, structural design, and mechatronics. It is very important for improving the air quality and It plays a big role in improving the comfort of drivers and passengers. The movement of the car sunroof glass generally adopts one of the outward opening type or the inner type, both of which are powered by motors. [0003] In the process of car sunroof matching, the first consideration is to meet the head space and vision requirements of the driver and passengers, while the traditional simple built-in sunroof will not only occupy part of the head space and affect part of the vision, but also cannot effectively...

Problems solved by technology

[0003] In the process of car sunroof matching, the first consideration is to meet the head space and vision requirements of the driver and passengers, while the traditional simple built-in sunroof not only occupies part of the head space and affects part of the vision, but also cannot effectively prevent ultraviolet radiation when fully opened

At the same time, the traditional simple outward-opening sunroof limits the space for passengers to stick their heads out of the roof, and the sealing effect is not good.
