Abstract
The utility model relates to a tailgating self-adaptive intelligent type translation energy-absorbing seat. When an accident occurs, a collision sensor installed on the intelligent type translation energy-absorbing seat sends information to a processor according to detected collision degree. After processor processes, instructions are sent to the motor and control the operation of the motor to drive a sliding block to slide. When the collision sensor detects that tailgating degree is high-speed tailgating, the motor drives the sliding block to slide. The sliding block extrudes an energy-absorbing steel sheet to plastically deform the energy-absorbing steel sheet, thereby further improving platform constraint force, and realizing stable rear sliding of the seat to prevent the neck of a passenger from being hurt. The tailgating self-adaptive intelligent type translation energy-absorbing seat is suitable for low-speed tailgating, mediate-speed tailgating and high-speed tailgating, and provides great platform constraint force during high-speed tailgating.

Principle of work of the present utility model:
Be illustrated in figure 9 the fundamental diagram of intelligent translational energy-absorbing seat of the present utility model.The initial position of general sliding shoe 14 is set to contact with energy-absorbing steel disc 10 but energy-absorbing steel disc 10 is not produced to squeezing action power.When occupant normally takes seat, the pressure sensor that is now positioned at seat bottom is measured occupant's body weight G immediately, if when G is less than or equal to 75Kg, sliding shoe 14 does not move; When if G is greater than 75Kg, motor 12 drives sliding shoe 14 to the direction motion 5mm of energy-absorbing steel disc 10, makes 14 pairs of energy-absorbing steel discs of sliding shoe 10 produce certain squeezing action power and makes energy-absorbing steel disc 10 produce elastic deformation but be unlikely to make energy-absorbing steel disc 10 that plastic deformation occurs.Then occupant stir according to demand regulating handle 7 forward or backward moved seat to desired location, release regulation handle 7, seat locking.When automobile bumps, if when crash sensor detects vehicle generation low speed rear-end collision, draw the threshold value of the power that the directed force F of 8, cylinder 9 and speed limit baffle plate provides lower than speed limit baffle plate 8, seat afterwards sliding motor 12 do not drive; If while there is middling speed collision, F is greater than this threshold value, after seat, sliding motor 12 does not drive; If while there is high speed rear-end collision, F is much larger than this threshold value, and sliding after seat and motor 12 drives sliding shoe 14 further to the 10 direction motions of energy-absorbing steel disc, causes energy-absorbing steel disc 10 that plastic deformation occurs, to obtain larger constraint platform power absorption system kinetic energy.When seat slide rearwardly to ultimate range, the bearing pin 24 that is positioned at guide plate 23 front ends is blocked to pin seat to front slide by the pin-and-hole 25 of dull and stereotyped guide groove 20 front ends, avoids occupant to be subject to other injury.
Above the utility model is described in detail; its object is to allow the personage who is familiar with this art can understand content of the present utility model and be implemented; can not limit protection domain of the present utility model with this; all equivalences of doing according to Spirit Essence of the present utility model change or modify, and all should be encompassed in protection domain of the present utility model.
