Embodiment Construction

[0013] like figure 1 As shown, the seat 1 is fixedly connected to the moving platform 12 of the multi-degree-of-freedom damping structure 2, and the static platform 11 of the parallel mechanism is fixedly connected to the vehicle floor.

[0014] combine figure 2 , the multi-degree-of-freedom vibration damping structure 2 is a five branch chain space parallel mechanism, which is composed of four identical branch chains and a main chain 5 in parallel, and a square dynamic platform 12 and a static platform 11. The branch chain consists of a ball pair, a moving pair, The ball pairs are composed in turn, branch chain A3, branch chain B4, branch chain C6, and branch chain D7 are formed in parallel, and are arranged at the four corners between the moving platform 12 and the static platform 11; the middle one is composed of a moving pair and a Hooke hinge 9 The main chain 5, the Hooke hinge 9 are connected with the static platform 11, and one end of the moving pair is rigidly connec...

Abstract

The invention discloses an automobile seat system with multi-dimension vibration reduction. A three-degree-of-freedom five-branch-chain space parallel-connection mechanism is used between the automobile seat and a chassis according to needs and is connected with a static platform in parallel through a movable platform ; the seat is fixedly connected with the movable platform of the parallel-connection mechanism, the static platform is fixedly connected with the chassis, the movable platform realizing the parallel-connection mechanism has vibration reduction function in three directions of x-axis rotation, y-axis rotation and z-axis movement, the branch chain of the parallel-connection connected mechanism comprises elastic damping vibration reduction elements. The invention can realize the vibration reduction of the automobile seat with multidegree of freedom by one layer of a simple structure.

Description

technical field [0001] The invention relates to the field of mechanical vibration damping devices, in particular to a combined elastic vibration damping car seat that uses a parallel mechanism plus elastic elements, damping elements, etc., and can be used for seat systems for heavy vehicles, agricultural vehicles, and commercial vehicles. Background technique [0002] With the continuous development of science and technology, human beings are increasingly dependent on various vehicles. The multi-dimensional vibration problems caused by vehicles, especially heavy trucks, engineering vehicles, agricultural vehicles, etc., when driving under poor road conditions have already affected the health of members and vehicles. Performance has an increasingly severe impact. As an important part in direct contact with the human body, the vehicle seat is the main body to reduce the impact of vibration on the human body. The natural frequency of the overall vibration should avoid the human...
