Operation principle
When user is sitting on the seat cushion 13 of ISD shock absorbing seats of the present invention, the gravity of user will act on
On the upper plate 12, the ISD damping modules contacted at this time with 12 inside location hole of the upper plate start stress.
The ISD Damping modules 14 are used to container 15, spring 16 and damper 17 to absorb energy, when used container by compression
After left end point 21 and used container right endpoint 29 are by directed force F, produce relative rotation between leading screw 27 and feed screw nut 26, at this time silk
Thick stick nut 26 is motionless, and leading screw 27 rotates and flywheel 23 is driven to rotate, and the rotation of flywheel 23 will produce inertia resistance to cut down the work
The firmly effect of F improves the comfort of seating to effectively decaying vibration.
During 14 forced compression of ISD Damping modules is used to container 15, spring 16 and damper 17, the scissors
The upper and lower ends level of two connecting rods of holder 7 is slided, to drive the upper plate 12 for being equipped with seat cushion 13 whole downwards
It is mobile, cushioning effect is played, until the support force of ISD dampings module 14 reaches balance with the pressure from upper plate 12.
Preferably, when ISD damping modules reach dynamic balance, the upper and lower ends of two connecting rods of the shear type frame 7 exist
When being not up to the extreme position of guide rail both sides on the cushion block 8, when jolting during taking at this time, in ISD damping moulds
During block stretching absorbance energy, connecting rod can follow moving up and down and remaining support appropriate for seat cushion 13, and unlikely
In making structure by rigid shock because reaching the extreme position of cushion block guide rail both sides.
After gravity removes, the ISD Damping modules 14 can reset under 16 resilient force of spring, while the scissors
The upper and lower ends level of two connecting rods of holder 7 is slided, and the shear type frame 7 drives the upper plate 12 for being equipped with seat cushion 13
Entirety moves up, and gradually returns to stationary state when non-stress.
When vehicle running surface unevenness is high, the lower plate 9 of ISD shock absorbing seats of the invention will be by upward
Power will produce upward vertical vibration under upward power acts on while with passenger's gravity, and ISD Damping modules 14 are logical at this time
Overcompression is used to container 15, spring 16 and damper 17 to absorb energy, decaying vibration, while the shear type frame 7 follows and band
It moves the upper plate 12 to move up and down, when compound action power reduces, the ISD Damping modules 14 can be in the elastic masterpiece of spring 16
With lower reset.
It is to be appreciated that describing the skill simply to illustrate that the present invention to what specific embodiments of the present invention carried out above
Art route and feature, its object is to allow those skilled in the art to can understand the content of the present invention and implement it accordingly, but
