What are the design considerations for noise control of plastic pick for car air outlet?
Publish Time: 2025-01-22
As a commonly used adjustment device in the car, the design of plastic pick for car air outlet should not only meet the requirements of convenient operation and aesthetics, but also make careful considerations in noise control to reduce abnormal noise during operation and provide drivers with a more comfortable and quiet driving environment.
In the early stage of the design of plastic picks, noise control should be included in the core considerations. The selection of materials is the basis. High-quality plastic materials not only have good toughness and durability, but also have a low friction coefficient and excellent anti-aging performance. Such material selection can effectively reduce the friction sound between the pick and the surrounding parts during operation, and maintain stable quiet performance under long-term use.
Structural design is also critical. In order to reduce noise, the connection design between the pick and the air outlet body needs to be very particular. Adopting precise mold manufacturing and assembly technology, ensure that the matching gap between the pick and the air outlet is as small as possible to reduce abnormal noise caused by looseness or excessive gap. In addition, the rotating shaft of the paddle should also adopt a low-noise design, such as adding lubricating grease or using self-lubricating materials to reduce friction noise during rotation.
In the operation part of the paddle, designers usually use ergonomic principles to design a curved surface shape that fits the hand grip, which not only improves the convenience of operation, but also reduces the additional noise caused by improper hand force during operation. At the same time, the surface treatment of the paddle is also very important. The use of delicate frosted or non-slip texture design can increase the friction between the paddle and the finger, prevent sliding during operation, and further reduce the generation of noise.
In addition, for some special usage scenarios, such as wind noise interference during high-speed driving, designers can also consider adding silencer cotton or other sound insulation materials to the paddle to further isolate the interference of external noise and improve the overall quiet effect in the car.
In summary, the design consideration of plastic pick for car air outlet in noise control is a comprehensive process involving material selection, structural design, and ease of operation. Through careful design and manufacturing, we can ensure that the paddles can maintain low noise levels when operating, providing the driver with a more comfortable and quiet driving environment.
