Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicle air outlets, more specifically to a fan blade support of an air outlet. BACKGROUND

[0002] The fan blade support of an automobile air outlet is an important component in the automobile air conditioning system. Its main function is to fix the fan blade and provide support, while allowing the fan blade to rotate within a certain range, thereby adjusting the direction of the air outlet to meet the comfort needs of the driver and passengers. Traditional fan blade supports usually use screw installation methods. Although this installation method is simple in structure, it has many defects in actual application. First, screw installation requires the provision of special tools such as screwdrivers or power tools, which increases the complexity of assembly and the labor intensity of workers. During the assembly process, the tightening force of the screws needs to be accurately controlled, otherwise it may cause the support to deform or the fan blade to loosen. In addition, screw installation also has the problem of low assembly efficiency, especially in mass production. This inefficient assembly method will significantly increase production costs. Second, the screw-installed fan blade support is prone to loosening during use. Due to the vibration during driving and the frequent rotation of the fan blade, the screws may gradually loosen, causing the fan blade to be misaligned, and even a safety hazard of the fan blade falling off. In addition, the screw installation method requires high assembly precision. If the screw position is not accurate or the screw hole machining error is large, the support may not be installed normally or may have assembly defects. This installation method may also affect the aesthetics of the automobile interior due to the exposure of the screws. In summary, the traditional screw-installed fan blade support has the defects of low assembly efficiency, poor reliability, and easy loosening, which makes it difficult to meet the requirements of modern automobiles for interior components to be efficient, reliable, and aesthetically pleasing. Therefore, developing a new fan blade support installation technology has become an important development direction for automobile interior design. SUMMARY
