The present invention relates to a method for reducing vibration of a headrest of a vehicle seat, a headrest vibration absorber and a vehicle. The method comprises the following steps: carrying out amodal test of the vehicle seat to obtain modal characteristics of the vehicle seat; carrying out a vehicle seat vibration test to obtain the maximum amplitude of a vehicle seat headrest when the vehicle is under an idling condition; determining the parameters of the headrest absorber according to the modal characteristics, the maximum amplitude, and the weight and the size of the headrest of the vehicle seat, wherein the parameters include the resonance frequency, the weight, the installation direction and the size of the headrest absorber, and the gap with the periphery; and manufacturing theheadrest absorber according to the parameters, and installing the headrest absorber on the headrest of the vehicle seat. According to the present invention, the vibration of the headrest can be directly reduced, so that the vibration amplitude transmitted from the headrest to the head of a passenger is greatly reduced, and even the vibration can be completely eliminated, so that the riding comfort can be obviously improved.
Description
technical field [0001] The invention relates to the technical field of vehicle seats, in particular to a method for reducing vibration of a headrest of a vehicle seat, a headrest shock absorber and a vehicle. Background technique [0002] The vibration of the vehicle seat is an important factor affecting the ride comfort of the vehicle. Especially in the idling condition, because the vibration excitation of the vehicle engine is large and the frequency is low, it is easy to arouse the vibration of the seat system. The headrest is located at the uppermost part of the vehicle seat system, so the vibration will be amplified to a certain extent, which will cause extreme discomfort to the occupant's head. For the seats of luxury models, the structure of the headrest is complex, so it is more common for the headrest to vibrate greatly. [0003] In this regard, in most cases, the vibration of the seat headrest is reduced by reducing the vibration of the seat at the installation p...
