A three-degree-of-freedom car seat vibration damping platform

Abstract

The invention discloses a car seat vibration reducing platform with three degrees of freedom, and belongs to the technical field of car seats. Two first vibration reducing branch chains are adopted to be connected between a fixed platform and a first movable platform, and two second vibration reducing branch chains are connected between the first movable platform and a second movable platform; the first movable platform can bear two-degree-of-freedom vibration of rotation around the x axis and vertical movement along the z axis relative to the fixed platform, and the second movable platform can bear two-degree-of-freedom vibration of rotation around the y axis and vertical movement along the z axis relative to the first movable platform and can achieve three-degree-of-freedom vibration reducing on rotation around the x axis, rotation around the y axis and vertical movement along the z axis. According to the car seat vibration reducing platform, the vibration reducing branch chains are high in rigidity and superior in vibration reducing performance, therefore, a driver can comfortably drive a car in a severe driving environment, and the current problem that the physical and mental health of the driver and passengers are seriously influenced due to the fact that an existing seat is bad in vibration reducing performance is solved; meanwhile, the structure is simple, and application and popularization are expected.

Description

technical field [0001] The invention belongs to the technical field of car seats, in particular to a three-degree-of-freedom car seat vibration damping platform. Background technique [0002] Under the general trend of rapid economic development in today's world, especially in China, since the reform and opening up, my country's machinery manufacturing industry has developed rapidly. There have been a number of car companies such as Changchun FAW, Hubei Shiyan No. 2 Automobile, and China Heavy Truck. More and more Most ordinary families have their own cars, so the car seat industry is also facing huge opportunities and challenges. For most cars, the cost of seats may be higher than the cost of the gearbox or even the body. [0003] Domestic automakers have developed rapidly in recent years, but they still lack independent intellectual property rights. Automakers often use sponges to absorb vibrations when designing car seats, but cars often produce violent shocks when passing...
