Description

A new type of vibration and noise reduction device

technical field

The utility model relates to the field of vibration and noise reduction devices, in particular to a novel vibration reduction and noise reduction device.

Background technique

With the development of economy and technology and the improvement of people's living standards, the comfort of the riding environment inside the car has also attracted more and more attention. NVH (Noise, Vibration, Harshness, Vibration and Harshness) is a measure of the ride inside the car. An important indicator of environmental comfort, optimizing the NVH performance of a vehicle can significantly improve the user's ride experience and improve the quality of the vehicle.

The noise of the vehicle air conditioner is one of the main noises of the NVH in the cabin. After the vehicle is turned on the air conditioner, the vibration of the compressor will be transmitted to the body through the air conditioner pipeline and the refrigerant, which will cause the whole vehicle to vibrate and generate noise. After the interior reaches the set temperature, the air-conditioning compressor will stop running, and when the temperature inside the car deviates from the set temperature, the air-conditioning compressor will re-run, which will have a pulse effect on the refrigerant in the air-conditioning pipeline, which will cause the air-conditioning pipe. The road vibrates and generates noise, which affects the NVH performance of the vehicle. At the same time, vibration will cause fatigue of related components and shorten their service life, which will inevitably lead to higher requirements on the quality of components and increase the cost.

With the development of industrialization, simple structure and noise control have become the goals pursued by the automotive market. At present, the structures related to vibration reduction and noise reduction of many automotive air conditioners are abnormally single (noise reduction cotton, vibration reduction pads, etc.), and the effect is not significantly improved. The vibration and noise reduction mechanism with relatively good effect has complex structure, large space occupation and high cost.
