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
The present invention relates to a kind of for motor vehicle novel two free shock absorbing seat mechanisms.Specifically, be a kind of elastic supporting mechanism between chair surface and vehicle base of invention, make seat can be in front and back, above-below direction realizes vibration damping simultaneously.This mechanism can be widely used on the seat suspension system on the agri-vehicle, engineering truck, military-designed vehicle of field work, thereby alleviates the vibration injury that chaufeur is subject to.。
Background technology
For vehicle such as the agri-vehicle of field work, engineering truck, military-designed vehicles, because work under bad environment, cause chaufeur to bear for a long time the high-intensity vibration of low frequency, thereby cause the occupational diseases such as vertebra distortion, stomach trouble, seriously damage the physical and mental health of chaufeur, reduce work efficiency.
At present, the shock absorbing seat suspension system of widespread use is mainly considered the vibration control of vertical direction, and the seat suspension element mainly contains metal spring, air bellow etc., and metal spring is the automotive seat damping element the earliest that occurs.In order to improve the adaptivity of metal spring, cluster spring has appearred subsequently, with the spring assembly use of different helical angles or different-stiffness, make its rigidity be non-linear, satisfy the dynamic characteristics of vibration, reduced to occur the probability of resonance, its vibration damping is further optimized.Since the nineties in 20th century, both at home and abroad adopt air bellow at the driver's seat of many goods carrying vehicles and motorcoach successively, improved significantly the traveling comfort of seat.
Yet the vibration that the field work vehicle bears is multi-dimensional vibration mostly, and traditional unidirectional vertical direction vibration damping mode can not satisfy the human requirement more and more higher to travelling comfort, is badly in need of seeking a kind of seat suspension mechanism that can realize multi-aspect while vibration damping.
Summary of the invention
The object of the invention provides a kind of Three-degree-of-freedom damping seat suspension fork mechanism, and this mechanism has following characteristics:
(1) the present invention adopts main load spring to cooperate crossbar group supporting mechanism, makes shock absorbing seat can realize simultaneously vibration damping of vertical direction, fore-and-aft direction, thereby alleviates multi-dimensional vibration to the injury of human body.
(2) this mechanism is simple in structure, compact, and motion is easy to production application flexibly.
The invention has the beneficial effects as follows:
((1) the present invention can improve the space oscillations of field work vehicle seat;
(2) provide new solution for the Vehicle damper seat.
Description of drawings
Below by accompanying drawing technology of the present invention is given to illustrate further.
Accompanying drawing 1 is structural representation of the present invention, connects firmly two identical side chains of fore-and-aft direction configuration between platform (16) and the base (10) between seat (1) and platform (16) by main loading spring (17).In the side chain, bar (14) one ends link to each other with platform (16) by revolute pair (15), the other end links to each other with slide block (12) by revolute pair (13), and the damper spring (11) with horizontal arrangement between slide block (12) and the base (10) is connected.Crossbar group by both sides between seat (1) and the base (10) supports, the crossbar group is comprised of the bar (6) and the bar (8) that link to each other by revolute pair (5) intersection, bar (6), bar (8) one ends link to each other with slide block (3), slide block (3 ') by revolute pair (4), revolute pair (4 ') respectively, and the other end links to each other with slide block (8), slide block (8 ') by revolute pair (7), revolute pair (7 ') respectively.Slide block (3), slide block (3 ') can slide along the guide rail that is connected in the seat both sides (2), and slide block (8), slide block (8 ') can slide along base (10) and guide rail (2) parallel direction.
Accompanying drawing 2 is generalized section of the present invention; Accompanying drawing 3 is virtual prototype of the present invention.
The specific embodiment
With reference to the accompanying drawings 1,16 on seat 1 and platform connect firmly by main loading spring 17, two identical side chains of fore-and-aft direction configuration between platform 16 and the base 10.In the side chain, bar 14 1 ends link to each other with platform 16 by revolute pair 15, and the other end passes through revolute pair 13 and links to each other with slide block 12, and the damper spring 11 with horizontal arrangement between slide block 12 and the base 10 is connected.Crossbar group by both sides between seat 1 and the base 10 supports, the crossbar group is comprised of the bar 6 and the bar 8 that link to each other by revolute pair 5 intersections, bar 6, bar 8 one ends respectively by revolute pair 4, revolute pair 4 ' with slide block 3, slide block 3 ' link to each other, the other end pass through respectively revolute pair 7, revolute pair 7 ' with slide block 8, slide block 8 ' link to each other.Slide block 3, slide block 3 ' can slide along the guide rail 2 that is connected in the seat both sides, slide block 8, slide block 8 ' can slide along base 10 and guide rail 2 parallel directions.
