Description

Technical Field

[0001] The present invention relates to the technical field of diffusers, and in particular to a forming process for spoiler vanes. Background Art

[0002] A vehicle diffuser is a device designed based on the principle of aerodynamics, mainly used to optimize the air flow at the bottom of the vehicle body, improve the high-speed stability and grip of the vehicle. Its core function is to generate a downward force by accelerating the air flow under the vehicle and reducing the air pressure difference, thereby "adsorbing" the vehicle onto the road surface; vanes are provided on the vehicle diffuser, and the vanes can dynamically adjust the angle on the vehicle diffuser to better meet the performance requirements of the vehicle in different driving scenarios.

[0003] In the prior art, a vane is disclosed, which includes a soft part and a rigid part connected to the soft part. A fixing part is provided on the soft part, an installation hole is formed on the fixing part, and a rigid bushing is provided in the installation hole. The rigid bushing is in interference fit in the installation hole, and the rigid bushing is used to connect with the vehicle diffuser. In this structure, the rigid bushing is installed in the installation hole after the soft part is formed, and the assembly is relatively complex. Moreover, the strength of the connection between the fixing part and the vehicle diffuser is concentrated on the rigid bushing, which easily causes the rest of the fixing part to bend and deform, thereby affecting the rotation of the rigid part. A vane mounting bracket is glued to the rigid part. The rigid part is made of carbon fiber, and the vane mounting bracket is made of metal. The vane mounting bracket is fixed only by gluing. This fixing method has poor structural strength, and it is easy for the two to separate during the high-speed driving of the vehicle.

[0004] Therefore, it is necessary to design a new technical solution to solve the above problems. Summary of the Invention

[0005] In view of this, in view of the deficiencies of the prior art, the main purpose of the present invention is to provide a forming process for spoiler vanes. By embedding studs in the upper die yarn material, the studs are buried in the installation position after the carbon fiber plate is formed. The mounting seat is fixed to the carbon fiber plate at one time by gluing, and the mounting seat is fixed to the carbon fiber plate at a second time by tightening the nuts. The double fixing method improves the connection strength between the mounting seat and the carbon fiber plate, enables the spoiler vane to be more stably connected to the vehicle body, and a metal strip is provided in the rubber part, and at least two mounting holes for connecting with the diffuser are provided on the metal strip. The setting of the metal strip improves the structural strength of the connection between the rubber part and the diffuser, makes the connection between the rubber part and the diffuser not easily deformed, and ensures that the carbon fiber plate can rotate normally.
