Embodiment Construction

[0014] According to attached figure 1 , the chair surface 1 and the platform 16 are fixedly connected by the main load spring 17, and two identical branch chains are arranged between the platform 16 and the base 10 in the front and back direction. In the branch chain, one end of the rod 14 is connected to the platform 16 through the swivel pair 15, and the other end is connected to the slider 12 through the swivel pair 13, and the slider 12 is connected to the base 10 with a vibration damping spring 11 arranged horizontally. The seat surface 1 and the base 10 are supported by cross bar groups on both sides. The cross bar group is composed of rod 6 and rod 8 which are cross-connected through swivel pair 5. ' is connected to slider 3 and slider 3', and the other end is connected to slider 8 and slider 8' through rotating pair 7 and rotating pair 7' respectively. The slide block 3 and the slide block 3' can slide along the guide rails 2 fixedly connected to both sides of the cha...

Abstract

The invention relates to a two-freedom-degree seat mechanism which can be used for damping the vibration of an engineering vehicle driver, and the two-freedom-degree seat mechanism is characterized in that a seat surface is connected with a movable platform through a main load spring, and two identical branched chains are arranged between the movable platform and a seat base in the longitudinal direction. In each branched chain, one end of a supporting rod is connected with the movable platform through a rotary pair, the other end is connected with a slide block through a rotary pair, and the slide block is connected with the base through a horizontal shock-absorption spring. Meanwhile, the seat surface and the base are supported through crossed rod groups which are respectively arranged on two sides of the seat, each crossed rod group consists of two supporting rods which are crossed through the rotary pair, one end of each supporting rod is connected with a slide block which can slide along a slide rail of the seat surface in the longitudinal direction through the rotary pair, and the other end is connected with a slide block which can slide along the base in the longitudinal direction through the rotary pair. The two-freedom-degree vehicle shock-absorption seat mechanism can realize the shock absorption function in the vertical direction and in the longitudinal direction and has characteristics of simplicity and compactness in structure and reliability in work and promising application prospect.

Description

technical field [0001] The invention relates to a novel two-free damping seat mechanism for vehicles. Specifically, it is to invent an elastic support mechanism between the seat surface and the vehicle base, so that the seat can simultaneously realize vibration reduction in the front, rear, up and down directions. The mechanism can be widely used in seat suspension systems of agricultural vehicles, engineering vehicles and military vehicles in field operations, so as to reduce the vibration damage suffered by drivers. . Background technique [0002] For vehicles such as agricultural vehicles, engineering vehicles, and military vehicles operating in the field, due to the harsh working environment, the driver is exposed to low-frequency and high-intensity vibrations for a long time, which causes occupational diseases such as spinal distortion and stomach disease, and seriously damages the driver's health. Physical and mental health, reduce work efficiency. [0003] At prese...
