Working principle of the present invention is as follows:
Magnetic force will be generated when magnetic powder coil 10 is powered, due to magnetic force effect and to attract magnetic powder to generate hardening existing
As, at this moment between the suction-operated of magnetic powder and magnetic powder under sucking action, magnetic powder limiter 12 generates damping force, so that
The damping fin 7 moved in position-limited box 5 is damped power and limits its movement, and then limits car door under the linkage of gag lever post 2 and open
It closes.Wherein, gag lever post 2 is to be able to satisfy the thin bar component for answering force request, and the work of traction damping fin 7 is played during opening/closing door of vehicle
With, and damping fin 7 is then roomy rectangular parallelepiped structure, width accounts for about the one third of 5 length of position-limited box, according to required damping
Power can appropriate adjustment its size so that it is met limitation car door the frictional force between magnetic powder when being slid in position-limited box 5 with increasing and close
Damping force required for closing.
More importantly vehicle-mounted computer, which can control linear current controller then and can control, flows through magnetic powder coil 10
The size of electric current generates damping force preferably with linear change.The damping force of linear change can satisfy different car doors and open
Ideal damping force under degree makes car door have linear aperture.
In order to which intelligent control flows through the size of 10 electric current of magnetic powder coil, preferably limited under different door opening degrees with generating
12 damping force of device needs vehicle-mounted computer to match the coil current data under different opening, and the opening size of car door can pass through
The displacement calculation that displacement sensor 6 inside position-limited box 5 measures obtains.
Power needed for reducing folding car door for intelligence, outward swinging door armrest positions (are below door lock in door in car door
Door guard bar is opened and closed, outdoors i.e. enabling handrail) installation pressure sensor, it is intended to incude firmly size when passenger opens and closes car door.Pressure
Force snesor is exported pressure size by corresponding current signal when being under pressure and acting on, when induction pressure is larger, explanation
Passenger's folding car door is firmly larger, and after the current signal at this moment exported will be handled by vehicle-mounted vehicle-mounted computer, output, which reduces, to be flowed through
The electric current of magnetic particle damper magnetic powder coil 10, and then reduce 12 damping force of limiter, final 12 damping force of limiter that reduces is given
Car door bring added burden is opened and closed, makes to open and close car door and compare to become light.
After the current signal of pressure sensor output is handled by vehicle-mounted computer, control 10 electric current of magnetic powder coil reduces
Amplitude and pressure sensor pressure size be it is linear, i.e., with the increase of induction pressure (pressure), electric current reduces amplitude and increases,
Until 12 damping force of limiter completely disappears, ensure that in this way reduce open and close car door when pulling force or while thrust,
Avoid damping force completely disappear suddenly to car door folding bring impact, bring insecurity, at the same avoid door opening degree compared with
Damping force is completely disappeared to impact to 13 bring of body hinge and be influenced when big, also guarantees that car door has certain absorption sense.
In car door moving process, the presence of induction pressure illustrates that car door is artificially manipulating, and executes above-mentioned intelligence and mitigates resistance
Buddhist nun's power process, and when induction pressure disappears, as car door is kept for the aperture moment, and vehicle-mounted computer adjusts flow through magnetic powder line immediately
The size of 10 electric currents is enclosed, guarantees that car door can stablize aperture where holding, causes car door to impact without damping force deficiency occurs.
(damping force size needed for door opening degree and 10 size of current of magnetic powder coil is flowed through in advance through overmatching, and be stored in vehicle-mounted vehicle
It carries in computer).
Above-mentioned Intelligent door moving process, all executes under the premise of meeting safety, and when not to be noted vehicle is all by passenger
When enclosing mobile pedestrian or vehicle and being switched on car door, intelligent car door open-close system issues slight alarm, exists side by side and passes through
The electric current of magnetic powder coil 10 reaches maximum value, i.e. 12 damping force of limiter reaches maximum, and limitation car door is further opened, and guarantees
Passenger and pedestrains safety.
Above-mentioned all intelligent process (i.e. car door opening or closing or car door are kept) all under car door lock opening state
It executes, and when car door lock is closed, intelligent car door open-close system is in close state.
Working method of the invention, comprising the following steps:
First, when car door is not switched on, intelligent car door open-close system is in close state；
Second, when car door lock is opened, intelligent car door open-close system is opened, first the pedestrian of detection vehicle periphery and movement
Whether vehicle meets car door opening safety condition；
Third, if meeting car door opening safety condition, car door can be normally-open；If not satisfied, then vehicle-mounted computer regulates and controls
So that the magnetic powder coil in magnetic particle damper makes magnetic particle damper obtain maximum damping force, passenger is prevented to open by maximum current
Car door is opened, and then guarantees passenger and pedestrains safety；
4th, car door can it is normally-open after, the vehicle-mounted computer door opening action different according to passenger, judge passenger loading, under
Vehicle or enabling, (handrail inside pressure sensors A senses power in car door, then passenger getting off car opens the door for shutdown；In car door outside handrail
Side pressure sensor B senses power, then passenger loading is closed the door；Car door outer armrest inside pressure sensor C senses power, then passenger
It gets on the bus enabling；Car door outer armrest outside pressure sensor D senses power, then passenger getting off car is closed the door；High position pressure passes outside car door
Sensor E senses power, then passenger getting off car is closed the door)；
5th, vehicle-mounted computer can linearly subtract with the increase (close door is laborious) of each pressure sensor induction force
The electric current passed through in small magnetic powder coil to reduce the damping force of magnetic particle damper, and then reduces power required when close door；
6th, if in passenger getting off car door opening process, intelligence system detection vehicle is threatened to pedestrian or moving vehicle gets off
Passenger safety, then vehicle-mounted computer regulates and controls so that the magnetic powder coil in magnetic particle damper obtains magnetic particle damper by maximum current
It obtains maximum damping force, prevents passenger's opening car door, and then guarantee passenger and pedestrains safety (with three)；
7th, in passenger switch car door, to keep car door in a certain aperture, as long as hand is left and helps by passenger at this time
Hand position, corresponding position pressure sensor incude the presence less than pressure, and vehicle-mounted computer regulates and controls magnetic powder coil 10 immediately at this time
Middle electric current is matched with corresponding aperture, and car door is kept to stablize in current aperture；
8th, after car door keeps a certain aperture, passenger again close door when, corresponding position senses the presence of pressure,
Vehicle-mounted computer reduces the electric current in magnetic powder coil 10 immediately, and then reduces 12 damping force of limiter, enables car door institute as above
It is normally-open to state progress.
Specific passenger getting on/off system work process is as follows:
(1) when passenger getting off car:
Car door lock is opened, and intelligent car door open-close system is opened.Firstly, pedestrains safety detection is carried out, if car door is unsatisfactory for out
Safety condition is opened, then vehicle-mounted computer control magnetic powder coil 10 is made 12 damping force of limiter reach maximum, made by maximum current
Passenger can not open car door immediately, while respond with the alarm song of very little, and reminding passengers are got off dangerous at this time；If car door satisfaction is opened
Safety condition is opened, then jaw opening sensor can constantly detect door opening degree at this time, and transmit opening amount signal, while vehicle to vehicle-mounted computer
Handrail inside pressure sensors A (enabling pressure sensor) induction passenger pushes pressure in door, is at this time transferred to pressure size

Visitor is pressed sensor with compared with high thrust, can be made the electric current of magnetic powder coil 10 very little at once, be facilitated passenger quick and light
Push car door open in ground).When a certain aperture passenger getting off car, or only by a certain aperture of car door opening, when passenger no longer acts on enabling
Handrail, handrail inside pressure sensors A can't detect pressure, while under lock open state, and system determines to protect at this time for car door
Aperture state is held, corresponding current signal is converted by the open position signal that jaw opening sensor conveys immediately, to magnetic powder coil
10 apply the electric current, and limiter 12 is made to restore due damping force under this door opening degree, final that car door is kept to stablize aperture.
After passenger loading, by door guard bar of inwardly pulling a cart come the door that cut-offs, at this moment car handrail outside pressure sensor B incudes
To pressure (shutdown movement), pressure information is transferred to vehicle-mounted computer by sensor B, and vehicle-mounted computer constantly reduces according to pressure size
The circulating current of magnetic powder coil 10 reduces 12 damping force of limiter, so that power needed for mitigating passenger's closed door is (if passenger
It is pressed sensor with larger pulling force, the electric current of magnetic powder coil 10 very little at once can be made, facilitate passenger quickly and easily
Shut car door).
(2) when passenger loading:
Lock is opened, and intelligence system is opened.Firstly, pedestrains safety detection is carried out, if car door is unsatisfactory for opening safety condition,
Then vehicle-mounted computer control magnetic powder coil 10 makes 12 damping force of limiter reach maximum, stand passenger can not by maximum current
Car door is opened, while responding with the alarm song of very little, reminding passengers open the door dangerous at this time；If car door, which meets, opens safe item
Part, then jaw opening sensor can constantly detect door opening degree at this time, and transmit opening amount signal, while car door outer armrest to vehicle-mounted computer
Inside pressure sensor C (vehicle external-open door sensor) incudes passenger's enabling pulling force, and pulling force (pressure) size is constantly transferred to vehicle
Computer is carried, by reducing the electric current of magnetic powder coil 10 linearly to mitigate dynamics when enabling (if passenger after vehicle-mounted computer processing
It is pressed sensor with larger pulling force, the electric current of magnetic powder coil 10 very little at once can be made, facilitate passenger quickly and easily
Open car door).The a certain aperture of car door opening is helped when passenger no longer acts on enabling when a certain aperture passenger loading, or only
Hand, handrail inside pressure sensor can't detect pressure, while under lock open state, and system determines to open at this time for car door holding
Degree state converts corresponding current signal for the open position signal that jaw opening sensor conveys immediately, applies to magnetic powder coil 10
Add the electric current, limiter 12 is made to restore due damping force under this door opening degree, it is final that car door is kept to stablize aperture, waiting Passengen
It gets on the bus or only keeps door opening degree.
After passenger getting off car, by inside cart outer door handle come the door that cut-offs, at this moment vehicle outer door handle outside pressure sensor D
Sense pressure (shutdown movement), pressure information is transferred to vehicle-mounted computer by sensor D, vehicle-mounted computer according to pressure size constantly
Reduce the circulating current of magnetic powder coil 10, reduces 12 damping force of limiter, thus power needed for mitigating passenger's closed door (if
Passenger is pressed sensor with compared with high thrust, can be made the electric current of magnetic powder coil 10 very little at once, be facilitated passenger quickly and light
Just car door is shut).
(3) shutdown movement supplement outside vehicle
Pass through door handle, but people's ordinary practice stance hand push car door in life outside above-mentioned (2) vehicle at closing time
Carry out closed door by upper bit, it is contemplated that the shutdown of people is accustomed to, or solution both hands are inconvenient to close the door and pass through arm etc. other
Physical feeling closed door problem also disposes a pressure sensor E in car door upper position here, when pressure sensor E feels
Pressure (shutdown movement) should be arrived, pressure information is transferred to vehicle-mounted computer by sensor E, and vehicle-mounted computer constantly subtracts according to pressure size
The circulating current of small magnetic powder coil 10 reduces 12 damping force of limiter, so that power needed for mitigating passenger's closed door is (if multiply
Visitor is pressed sensor with compared with high thrust, can be made the electric current of magnetic powder coil 10 very little at once, be facilitated passenger quick and light
Car door is shut on ground), to meet the daily shutdown habit of people.In view of this, the present invention is directed to propose it is a kind of intelligence vehicle door spacing, with
