Abstract

The invention discloses an automobile skylight component. The skylight component comprises a skylight bracket, an automobile top and skylight glass, wherein a skylight opening is formed in the automobile top, changing the position of the skylight glass on the skylight bracket can enable the skylight opening to be in an opened state or a closed state, when the skylight opening is in the opened state, a spoiler which is higher than the outer wall of the automobile top is arranged on the front side of the skylight opening in a protruded manner, and an effective opening is formed in the skylight glass relative to the automobile top; the size of the height of the spoiler and the size of the length of the effective opening formed in the automobile top relative to the skylight glass satisfy a definite proportional relation. Through use of the automobile skylight component disclosed by the invention, the aerodynamic noise performance of the whole automobile can be optimized, and on the basis of eliminating specific automobile speed wind vibration noise, the high-speed wind noise of the automobile is effectively reduced.

Description

technical field [0001] The invention relates to the field of automobile manufacturing, in particular to an automobile sunroof assembly capable of simultaneously reducing vehicle high-speed wind noise and specific vehicle speed wind vibration sound. Background technique [0002] In the prior art, due to the unreasonable design of the height of the spoiler and the size of the effective opening of the sunroof glass relative to the roof, when the vehicle moves at a certain speed and the sunroof glass of the vehicle is in the open state, the airflow attached to the roof will flow through the sunroof. The opening is destabilized, creating flow separation. For example: when the airflow generates vortices or breaks up at the front edge of the sunroof opening, it will cause fluctuations in air pressure, forming the sound source of vehicle high-speed wind noise or wind vibration sound at a specific speed; when the airflow occurs at the rear edge of the sunroof opening When broken, it...
