Auto against adaptive multistage crash energy absorption equipment based on above-mentioned, the control process of auto against adaptive multistage crash energy absorption equipment is:
When automobile does not run into crisis situation in the process of moving, energy absorption device is in initial condition, the first master cock 4 and the second master cock 5 are in off-state, energy-absorbing inner tube 2 under the magnetic action of 12 pairs of the first electromagnet 7 of permanent magnet in energy-absorbing outer tube 1 inside, and remain static, elastic component 9 is in energy storage state;
Speed sensor on automobile and rang sensor detect in real time automobile self road speed and and the place ahead obstacle between distance and send this speed signal and range signal to self-adaptive control module, self-adaptive control module judges according to this speed signal and range signal whether this automobile likely bumps against with the place ahead obstacle, if control module judgement likely bumps with the place ahead obstacle, self-adaptive control module send electric signal control the first master cock 4 closures make the first electromagnet 7 energising produce magnetic force and its two ends magnetic pole adjacent to each other with permanent magnet 12 identical, thereby the repulsion that produces homopolar-repulsion ejects energy-absorbing inner tube 2 outside energy-absorbing outer tube 1, when energy-absorbing inner tube 2 arrives energy-absorbing outer tube 1 top, limiting stopper 11 will limit energy-absorbing inner tube 2 to be continued to eject forward, and energy-absorbing inner tube 2 ejects after elastic component 9, elastic component 9 is released and can be made lock pin 8 ejections interlocking energy-absorbing inner tube 2 move along its axis and energy-absorbing inner tube 2 is fixed to prevent energy-absorbing inner tube 2,
After energy-absorbing inner tube 2 ejects, self-adaptive control module still judges according to this speed signal and range signal whether this automobile likely bumps against with the place ahead obstacle in real time, if judgement no longer may bump, self-adaptive control module sends electric signal and controls the first master cock 4 disconnections, the second master cock 5 closures make the first electromagnet 7 generation magnetic force and itself and permanent magnet 12 two ends adjacent to each other different, the second electromagnet 10 produces magnetic force by lock pin 8 retractions simultaneously, energy-absorbing inner tube 2 is again retracted in energy-absorbing outer tube 1 by suction that heteropole is inhaled mutually and is waited for ejection next time, thereby the self adaptation that has realized auto against multi-buffer energy absorption device ejects and retracts.
The whole implementation mode of this auto against adaptive multistage crash energy absorption equipment is: the in the situation that of low speed, the energy-absorbing inner tube 2 of this energy absorption device can not be triggered and eject, if at this moment bumped, what first bump with obstacle is bumper/spoiler sandwich style 3 foremost, form the one-level energy-absorbing stage, this stage absorbs energy by the festering of exterior skin, the compression of filled rubber and the flexural deformation of collision prevention girders.Now energy-absorbing inner tube 2 and energy-absorbing outer tube 1 do not participate in the effect that energy-absorbing only plays support.And this sandwich style safety lever 3 is comprised of plastic skin, filled rubber and collision prevention girders, rigidity is lower, and pedestrains safety is also had to good protective effect.When the obstacle distance that reaches certain speed of a motor vehicle and car body and the place ahead when automobile is less than certain limit (the present embodiment is chosen 600mm), energy-absorbing inner tube 2 just can be ejected, now the energy of collision is larger, the energy-absorbing of dependence sandwich style bumper/spoiler 3 cannot be complete by crash energy absorption, energy-absorbing inner tube 2 is controlled to eject by self-adaptive control module and is participated in energy-absorbing, collision energy is by reaching the effect of energy-absorbing to the conquassation of energy-absorbing inner tube, this this is secondary energy-absorbing, this stage sandwich style bumper/spoiler 3 and energy-absorbing inner tube 2 participates in energy-absorbings and energy-absorbing outer tube 1 does not participate in energy-absorbing, 1 of energy-absorbing outer tube is played a supporting role to secondary energy absorption device.The energy that secondary energy absorption device absorbs when collision energy is enough large cannot be by crash energy absorption totally, and at this moment obstacle will directly collision occur with car body, and energy-absorbing outer tube 1 will participate in energy-absorbing and further consume crash energy, and this is three grades of energy-absorbings.By the energy-absorbing of front two-stage, crash energy has been absorbed major part, at this moment collides the damage of car body is reduced, and actv. has been protected the safety of the interior member of car and property.By being divided into three grades of energy-absorbings, increase collision energy-absorbing space, improved energy-absorbing efficiency, greatly improved the safety of running car.
The above, it is only the utility model preferred embodiment, therefore can not limit according to this scope that the utility model is implemented, the equivalence of doing according to the utility model the scope of the claims and description changes and modifies, and all should still belong in the scope that the utility model contains.
