Description
Technical Field
The invention relates to the technical field of automobile parts, in particular to an automobile upright post flow guide structure.
Background
The common car body has three columns, namely a front column (A column), a middle column (B column) and a rear column (C column) from front to back. For cars, the pillars, in addition to supporting, also function as door frames. The front of the column is a connecting column which is connected with the roof and the front cabin at the left front and the right front. The front column is between the engine compartment and the cockpit, and above the left and right rearview mirrors, can block part of the turning vision, especially the left turning, so the discussion is more. The designer must also consider the angle at which the front pillar obscures the driver's view when considering the front pillar geometry scheme. The center pillar supports not only the roof but also the front and rear doors, and additional parts such as a seat belt of the front seat and a wire harness are provided in the center pillar. Therefore, the center pillar has an outward convex radius to ensure a good force transmission performance. The cross-sectional shape of the center pillar of a modern car is relatively complex and is formed by welding a plurality of stamping steel plates. With the development of automobile manufacturing technology, a closed section center pillar which is directly formed by hydraulic forming without welding has been published, the rigidity of the closed section center pillar is greatly improved, the weight of the closed section center pillar is greatly reduced, and the closed section center pillar is beneficial to the light weight of modern cars. However, some designers have eliminated the center pillar in a cable manner from the standpoint of the convenience of the passenger for getting on and off the vehicle. The rear column is different from the front column and the center column in that the problems of sight line obstruction, getting-on and getting-off obstacles and the like do not exist, so the structure size is large, and the key is that the sealing performance of the rear column and the vehicle body is reliable. The rigidity is an index of automobile body design, and refers to the capability of the automobile body not easy to deform when a common external force which does not damage the automobile body is applied, namely the elastic deformation capability of recovering the original shape.
When the automobile runs at a high speed, wind noise is generated due to the friction between airflow and the automobile body. Wind noise outside the car transmits in the car, become the most main noise source in the car, the car stand of patent number CN 107031742A application, set up the air jet on the surface, utilize the air supply system in the car to aerify, and then form the air curtain, make external air current can not blow the window on the friction, and then the noise elimination, but air supply system is the electrical equipment of controller control in this patent, waste certain electric power, and the air jet setting is on the surface, very easily blockked up by mud and insect, openly set up the hole simultaneously, influence the aesthetic property of stand.
