Description
Technical field
The present invention relates to a kind of seat, particularly a kind of more failure-free seat suspension mechanism.
Background technology
In the truck seat, suspension mechanism is an important function structure on the seat, in abominable running environment, reduces the injury that vibration produces the occupant.Along with the development of China's automobile industry, auto sale universal day by day, terminal client begins to pay attention to the comfortableness problem of seat, and comfortableness problem receives increasing concern.Existing state inner suspension field, kind is single, all is the cooperation of fork configuration collocation slide block, and this cooperation has high requirements to production level and material property, if the out of reach corresponding requirements can make seat produce the problem of seriously rocking.Existing suspension seat, the suspension quantity not sufficient, rock serious.
Summary of the invention
The purpose of this invention is to provide a kind of more failure-free seat suspension mechanism, the present invention will solve the suspension quantity not sufficient of existing truck seat existence and rock serious problem.The present invention uses revolute pair to replace suspended slider, and traditional sliding pair is replaced to revolute pair, eliminates on-link mode (OLM) uncontrollable and that control is difficult relatively; Simultaneously simplify original mechanism significantly, simplified making, reduced assembly difficulty.The present invention has enough suspension amounts, and no shaking phenomenon takes place.
The present invention is made up of underframe, rigidity setting device and upper frame, and the rigidity setting device is between underframe and upper frame, and the rigidity setting device is made up of inner support, outer support, two springs, damper and rigidity adjustment assemblies; Upper frame is made up of front bezel, back frame, left frame and left frame, and inner support and outer support are formed inner scissor, and the upper end of inner support is hinged with the dual side-edge of back frame; Two lower ends of inner support are hinged with two first connecting rods respectively, and the other end and the underframe of first connecting rod are hinged, and two lower ends of outer support are hinged with underframe respectively; Two upper ends of outer support are hinged with two second connecting rods respectively, and the other end of two second connecting rods is hinged with left frame and left frame respectively, and back scuncheon is fixed with cross bar; Rigidity adjustment assembly is made up of pull bar, lever, self-box and adjusting screw(rod); Lever is arranged in self-box, and adjusting screw(rod) passes self-box and lever, and lever connects with adjusting screw(rod) with nut; The fulcrum and the self-box of lever are hinged; The other end and the pull bar of lever are hinged, and an end of two springs is hooked on two ends of pull bar respectively, and the other end of two springs is hooked on the cross bar; Expose from upper frame the end of adjusting screw(rod), and damper is oblique to be arranged between underframe and the upper frame.
Beneficial effect of the present invention: the present invention has enough suspension amounts, and no shaking phenomenon takes place.

The specific embodiment
See also Fig. 1, Fig. 2 and shown in Figure 3, present embodiment is made up of underframe 1, rigidity setting device 2 and upper frame 3, and rigidity setting device 2 is between underframe 1 and upper frame 3; Rigidity setting device 2 is made up of inner support 21, outer support 22, two springs 23, damper 24 and rigidity adjustment assemblies 25; Upper frame 3 is made up of front bezel 31, back frame 32, left frame 33 and left frame 34, and inner support 21 is formed inner scissor with outer support 22, and the upper end of inner support 21 is hinged with the dual side-edge of back frame 32; Two lower ends of inner support 21 are hinged with two first connecting rods 26 respectively; The other end of first connecting rod 26 and underframe 1 are hinged, and two lower ends of outer support 22 are hinged with underframe 1 respectively, and two upper ends of outer support 22 are hinged with two second connecting rods 27 respectively; The other end of two second connecting rods 27 is hinged with left frame 33 and left frame 34 respectively; Back frame 32 inboards are fixed with cross bar 35, and rigidity adjustment assembly 25 is made up of pull bar 251, lever 252, self-box 253 and adjusting screw(rod) 254, and lever 252 is arranged in self-box 253; Adjusting screw(rod) 254 passes self-box 25 and lever 252; Lever 252 connects with adjusting screw(rod) 254 with nut 255, and the fulcrum of lever 252 and self-box 253 are hinged, and the other end of lever 252 and pull bar 251 are hinged; One end of two springs 23 is hooked on two ends of pull bar 251 respectively; The other end of two springs 23 is hooked on the cross bar 35, and expose from upper frame 3 end of adjusting screw(rod) 254, damper 24 oblique being arranged between underframe 1 and the upper frame 3.
Principle of work of the present invention is:
After upper frame 3 received gravity and presses down, interior inner support 21, outer support 22 drew in, and two springs 23 are stretched, and damper 24 is compressed, and plays the effect of suspension; When rotation adjusting screw rod 254, elongate two springs 23 after, rigidity of the present invention increases, shorten two springs 23 after, rigidity of the present invention reduces.
