Description
Technical Field
The invention relates to a safe opening system of an automobile, in particular to an intelligent automobile door limiting and opening and closing system.
Background
The door stopper is used for limiting the opening degree of the door, and on one hand, the door stopper can limit the maximum opening degree of the door and prevent the door from being opened too much, so that the outer plate of the door is collided with the vehicle body; on the other hand, the door can be kept open when needed, and the door can not be automatically closed when the automobile is stopped on a slope or in the wind.
The main working part of the traditional vehicle door limiter is a limiting arm, one end of the limiting arm is hinged to the side wall of a vehicle body, the other end of the limiting arm is provided with a limiting stop block, a limiting box is arranged between the two ends, a limiting hole for the limiting arm to pass through is formed in the center of the limiting box, the limiting box is fixed on a vehicle door inner plate, and when the vehicle door is opened or closed, the limiting arm moves left and right in the limiting box.
However, the conventional purely mechanical door check, such as the most widely used draw-bar box type door check and spring type door check, generally has only 1-level or 2-level limit, and the high-grade vehicle has 3-level limit, and this structure causes the check not to have linear damping force, thereby causing the following troubles for opening and closing the door:
(1) when the door is pushed open, the door can be pushed open by a large force, and the thrust is correspondingly increased along with the increase of the opening degree of the door;
(2) the limiting groove is fixed by the limiting device, so that the opening degree of the vehicle door is not linear, and the vehicle door is easy to move between the two limiting grooves, so that the vehicle door always rebounds at a small angle when the vehicle door needs to be opened at a certain angle (or the maximum opening degree);
(3) the damping generated by the deformation of the elastic rubber block is usually small and is easy to wear and age, so that the damping force is reduced. The door opening or closing under special terrain conditions such as a slope still has large impact and is easy to scratch other vehicles or pedestrians, so that accidents are caused, and the door hinge is easy to damage after long-term use.
(4) However, in terms of door opening safety, the conventional vehicle has almost no automatic door locking (or emergency locking) function. If the vehicle is not found to be near or approaching, and the passenger does not notice the situation and gets off and opens the door, the door cannot be automatically locked, and the safety of the passenger and the pedestrian cannot be guaranteed.

the rotating pin base 1 is fixed in the vehicle body; the limiting box 5 is divided into an upper layer and a lower layer by the sealing partition plate 9, and granular magnetic powder and the damping sheet 7 are placed in a space formed by the sealing partition plate 9 and the bottom of the limiting box 5; a magnetic powder coil 10 is arranged in an interlayer formed by the sealing partition plate 9 and the limiting box cover plate 11; the limiting box 5, the magnetic powder, the damping sheet 7, the sealing partition plate 9 and the limiting box cover plate 11 form a magnetic powder limiter 12;
the magnetic powder baffle plate 4 is arranged at the through hole of the limiting box 5 and is penetrated by the limiting rod 2.
The damping fin 7 is of a cuboid structure;
the magnetic powder coil 10 is connected with a linear current controller through a cable, and the linear current controller is connected with a vehicle-mounted computer;
a displacement sensor 6 is arranged in the limit box 5;

and the displacement sensor 6, the pressure sensor A, the pressure sensor B, the pressure sensor C, the pressure sensor D and the pressure sensor E are respectively connected with a vehicle-mounted computer through control lines.
The working principle of the invention is as follows:
when the magnetic powder coil 10 is electrified, magnetic force is generated, the magnetic powder is attracted to generate hardening phenomenon due to the action of the magnetic force, at the moment, under the adsorption action of the magnetic powder and the attraction action among the magnetic powder, the magnetic powder limiter 12 generates damping force, so that the damping sheet 7 moving in the limiting box 5 is limited to move by the damping force, and the opening and closing of the vehicle door are further limited under the linkage of the limiting rod 2. Wherein, gag lever post 2 is the slender rod component that can satisfy the stress requirement, plays the effect of drawing damping fin 7 at door switching in-process, and damping fin 7 is wide cuboid structure then, and its width accounts for about the third of spacing box 5 length, can suitably adjust its size according to required damping force to increase when sliding in spacing box 5 and the frictional force between the magnetic, make it satisfy the required damping force of restriction door closure.
More importantly, the vehicle-mounted computer can control the linear current controller and then can control the current flowing through the magnetic powder coil 10, so as to generate ideal damping force with linear change. The linearly changing damping force can meet the ideal damping force under different door openness, so that the door has linear openness.
In order to intelligently control the magnitude of the current flowing through the magnetic powder linear coil 10 to generate an ideal damping force of the stopper 12 under different door opening degrees, the on-board computer is required to match coil current data under different door opening degrees, and the door opening degree can be calculated through the displacement measured by the displacement sensor 6 in the stopper box 5.
For the required power of intelligence reduction door that opens and shuts, install pressure sensor at the inside and outside handrail position of opening a door (the inside handrail that opens a door below promptly, the outside handrail that opens a door promptly of door) of door, aim at the response passenger the size of exerting oneself when opening and shutting the door. Pressure sensor passes through corresponding current signal output with pressure size when receiving pressure effect, and when induction pressure was great, it was great that the passenger opened and shut the door hard, and the current signal of at this moment output will be through on-vehicle computer processing back, and the output reduces the electric current of flowing through magnetic powder attenuator magnetic coil 10, and then reduces stopper 12 damping force, finally reduces the extra burden that stopper 12 damping force brought for the door that opens and shuts, makes the door that opens and shuts compare and relax.
After the current signal that pressure sensor output passes through on-vehicle computer processing back, the range that the control magnetic linear coil 10 electric current reduces is linear with pressure sensor pressure size, along with the increase of induced pressure (pressure), the electric current reduces the range and increases, until stopper 12 damping force disappears completely, just so guaranteed when pulling force or thrust when reducing the door of opening and shutting, also avoided the damping force suddenly complete disappearance to bring the impact for the door is opened and shut, bring the insecurity, the damping force disappears completely when avoiding the door aperture great simultaneously and brings the impact influence for door hinge 13, also guarantee that the door has certain absorption sense.
In the process of opening and closing the vehicle door, the existence of the induction pressure indicates that the vehicle door is manually operated, the intelligent damping force reducing process is executed, and when the induction pressure disappears, namely the vehicle door keeps the opening, the vehicle-mounted computer immediately adjusts the current flowing through the magnetic powder coil 10, so that the condition that the vehicle door can stably keep the opening is ensured, and the vehicle door impact caused by insufficient damping force can not occur. (the damping force required by the opening degree of the vehicle door is matched with the current flowing through the magnetic powder coil 10 in advance and is stored in a vehicle-mounted computer).
Above-mentioned door intelligence process of opening and shutting all carries out under the prerequisite that satisfies safety, and when the passenger did not notice pedestrian or the vehicle that the vehicle moved around just opened the door, intelligence door system of opening and shutting sends slight alarm sound to make the electric current of flowing through magnetic powder coil 10 reach the maximum value immediately, stopper 12 damping force reaches the biggest promptly, restricts the door and further opens, guarantees passenger and pedestrian's safety.
All the above intelligent processes are performed in the door lock open state (i.e. the door is opened or closed or the door is kept), and when the door lock is closed, the intelligent door opening and closing system is in the closed state.
The working method of the invention comprises the following steps:
firstly, when the vehicle door is not opened, the intelligent vehicle door opening and closing system is in a closed state;
secondly, when the door lock is opened, the intelligent door opening and closing system is opened, and whether pedestrians and moving vehicles around the vehicle meet door opening safety conditions or not is detected;
thirdly, if the safety condition of opening the vehicle door is met, the vehicle door can be normally opened; if the current does not meet the requirement, the vehicle-mounted computer regulates and controls the magnetic powder coil in the magnetic powder damper to pass through the maximum current, so that the magnetic powder damper obtains the maximum damping force to prevent passengers from opening the vehicle door, and the safety of the passengers and pedestrians is further ensured;
fourthly, after the vehicle door can be normally opened, the vehicle-mounted computer judges whether the passenger gets on or off the vehicle or opens or closes the door according to different door opening actions of the passenger (the pressure sensor A at the inner side of the armrest inside the vehicle door senses the force, the passenger gets off the vehicle and opens the door, the pressure sensor B at the outer side of the armrest inside the vehicle door senses the force, the passenger gets on the vehicle and closes the door, the pressure sensor C at the inner side of the armrest outside the vehicle door senses the force, the passenger gets on the vehicle and opens the door, the pressure sensor D at the outer side of the armrest outside the vehicle door senses the force, the passenger gets off the vehicle;
fifthly, the vehicle-mounted computer can linearly reduce the current passing through the magnetic powder coil along with the increase of the inductive force of each pressure sensor (the door is opened and closed difficultly), so that the damping force of the magnetic powder damper is reduced, and the force required for opening and closing the door is further reduced;
sixthly, if the passenger gets off and opens the door, the intelligent system detects that the passenger gets on or moves the vehicle and threatens the safety of the passenger getting off, the vehicle-mounted computer regulates and controls to enable the magnetic powder coil in the magnetic powder damper to pass through the maximum current, so that the magnetic powder damper obtains the maximum damping force, the passenger is prevented from opening the door, and the safety of the passenger and the passenger is further ensured (the same as the third step);
seventhly, when a passenger opens and closes the vehicle door, if the vehicle door is required to be kept at a certain opening degree, the pressure sensor at the corresponding position can not sense the pressure when the passenger leaves the armrest position, and the vehicle-mounted computer immediately regulates and controls the current in the magnetic powder coil 10 to be matched with the corresponding opening degree, so that the vehicle door is kept at the current opening degree stably;
eighthly, after the vehicle door keeps a certain opening degree, when the passenger opens and closes the vehicle door again, the corresponding position senses the pressure, the vehicle-mounted computer immediately reduces the current in the magnetic powder coil 10, and further reduces the damping force of the stopper 12, so that the vehicle door can be normally opened as described above.
The working process of the passenger getting-on and getting-off system is as follows:
(1) when passengers get off the vehicle:
and the door lock is opened, and the intelligent door opening and closing system is opened. Firstly, carrying out pedestrian safety detection, and if the vehicle door does not meet the opening safety condition, controlling the magnetic powder coil 10 to pass through the maximum current by the vehicle-mounted computer to enable the damping force of the limiter 12 to reach the maximum value, so that passengers cannot open the vehicle door immediately, and simultaneously reporting a small alarm sound to remind the passengers that the vehicle is unsafe to get off at the moment; if the door satisfies and opens the safe condition, then this moment opening sensor can detect the door opening often to on-vehicle computer transmission aperture signal, simultaneously the passenger pushes away a door pressure is responded to the inboard pressure sensor A of door armrest (the pressure sensor that opens the door), transmit the pressure size for on-vehicle computer this moment, on-vehicle computer handles the back and reduces magnetic powder nature coil 10's electric current through the linearity in order to alleviate the dynamics when opening the door (if the passenger uses great thrust to exert pressure the sensor, can make magnetic powder nature coil 10's electric current very little at once, make things convenient for the passenger to push the door open fast and lightly). When a passenger gets off the vehicle with a certain opening degree or only opens the vehicle door with a certain opening degree, when the passenger does not act on the door opening handrail any more, the pressure sensor A on the inner side of the handrail can not detect the pressure, and simultaneously, under the unlocking state of the vehicle lock, the system judges that the vehicle door keeps the opening degree state at the moment, immediately converts an opening degree position signal transmitted by the opening degree sensor into a corresponding current signal, applies the current to the magnetic powder coil 10, so that the limiter 12 recovers the damping force which is required under the opening degree of the vehicle door, and finally keeps the stable opening degree of the vehicle door.
After the passenger gets on the bus, close the door through inside sliding door handrail, at this moment in the car handrail outside pressure sensor B sense pressure (the action of closing the door), sensor B gives on-vehicle computer with pressure information transmission, on-vehicle computer reduces magnetic powder nature coil 10's circulating current according to pressure size often, reduce stopper 12 damping force, thereby alleviate the passenger and close the required power of door (if the passenger uses great pulling force sensor of exerting pressure, can make magnetic powder nature coil 10's electric current very little at once, make things convenient for the passenger to close the door fast and lightly).
(2) When a passenger gets on the vehicle:
and unlocking the vehicle lock and unlocking the intelligent system. Firstly, carrying out pedestrian safety detection, and if the vehicle door does not meet the opening safety condition, controlling the magnetic powder coil 10 to pass through the maximum current by the vehicle-mounted computer to enable the damping force of the limiter 12 to reach the maximum value, so that a passenger cannot open the vehicle door immediately, and simultaneously reporting a very small alarm sound to remind the passenger that the door is unsafe to open at the moment; if the door satisfies and opens the safe condition, then this moment opening sensor can detect the door opening often, and transmit the opening signal to on-vehicle computer, door inside handrail inboard pressure sensor C (the outer sensor that opens the door of car) response passenger's pulling force that opens the door simultaneously, give on-vehicle computer with pulling force (pressure) size transmission often, on-vehicle computer handles the back and reduces the electric current of magnetic powder nature coil 10 through the linearity in order to alleviate the dynamics when opening the door (if the passenger uses great pulling force to exert pressure the sensor, can make the electric current of magnetic powder nature coil 10 very little at once, make things convenient for the passenger to open the door fast and lightly. When a passenger gets on the vehicle with a certain opening degree or only opens the vehicle door with a certain opening degree, when the passenger does not act on the door opening handrail any more, the pressure sensor on the inner side of the handrail can not detect the pressure, and simultaneously, under the condition that the vehicle lock is opened, the system judges that the vehicle door keeps the opening degree state at the moment, immediately converts an opening degree position signal transmitted by the opening degree sensor into a corresponding current signal, applies the current to the magnetic powder coil 10, enables the limiting stopper 12 to recover the damping force corresponding to the opening degree of the vehicle door, finally keeps the stable opening degree of the vehicle door, and waits for the passenger to get on the vehicle.
After the passenger gets off the car, close the door through inside shallow outer door handle, at this moment outer door handle outside pressure sensor D senses pressure (the action of closing the door), sensor D gives on-vehicle computer with pressure information transmission, on-vehicle computer reduces magnetic powder nature coil 10's circulating current according to pressure size often, reduce stopper 12 damping force, thereby alleviate the passenger and close the required power of door (if the passenger uses great thrust to exert pressure the sensor, can make magnetic powder nature coil 10's electric current very little at once, make things convenient for the passenger to close the door fast and lightly).
(3) Door closing motion supplement outside vehicle
Above-mentioned (2) pass through the door handle when the external door is closed, but people usually are used to the standing posture and close the door by upper position with the hand push door in the life, consider people's the habit of closing the door, or solve the inconvenient door of closing of both hands and close the door problem through other health positions such as arm, here also settle a pressure sensor E in the door by upper position, when pressure sensor E senses pressure (the action of closing the door), sensor E gives on-vehicle computer with pressure information transmission, on-vehicle computer reduces the circulation current of magnetic powder nature coil 10 often according to pressure size, reduce stopper 12 damping force, thereby alleviate the passenger and close the required power of door (if the passenger uses great thrust to pressurize the sensor, can make the electric current of magnetic powder nature coil 10 very little at once, make things convenient for the passenger to close the door fast and lightly), in order to satisfy people daily habit of closing. In view of the above, the present invention is directed to an intelligent door check for intelligently controlling the damping force of the door check 12 during the opening process of the door, so that the opening and closing of the door becomes easy; meanwhile, the vehicle door has linear opening, namely the vehicle door can keep any opening within the maximum opening, and can stably keep the opening of the vehicle door under the conditions of a ramp and large impact in special cases; finally and above all, the door lock can be freely controlled in case of emergency to limit the door opening.

the magnetic powder baffle plate (4) is arranged at the through hole of the limiting box (5) and is penetrated by the limiting rod (2);
the damping fin (7) is of a cuboid structure;
the magnetic powder coil (10) is connected with a linear current controller through a cable, and the linear current controller is connected with a vehicle-mounted computer;
a displacement sensor (6) is arranged in the limiting box (5);
the pressure sensor A is arranged on the inner side of the armrest on the inner side of the vehicle door and is used for sensing the thrust when the lower vehicle door is opened;
the outer side of the armrest at the inner side of the vehicle door is provided with a pressure sensor B for sensing the pulling force when the vehicle is closed;
the pressure sensor C is arranged on the inner side of the armrest on the outer side of the vehicle door and used for sensing the pulling force when the vehicle is opened;
the pressure sensor D is arranged on the outer side of the armrest on the outer side of the vehicle door and used for sensing the thrust when the vehicle gets off and closes;
a pressure sensor E is arranged at the position, close to the B column, of the outer side of the vehicle door and used for sensing the thrust when the lower vehicle is closed;
the displacement sensor (6), the pressure sensor A, the pressure sensor B, the pressure sensor C, the pressure sensor D and the pressure sensor E are respectively connected with a vehicle-mounted computer through control lines;
the working method of the whole system comprises the following steps:
firstly, when the vehicle door is not opened, the whole system is in a closed state;
secondly, when the door lock is opened, the whole system is opened, and whether pedestrians and moving vehicles around the vehicle meet the door opening safety condition or not is detected;
thirdly, if the safety condition of the opening of the vehicle door is met, the vehicle door is normally opened; if the current does not meet the requirement, the magnetic powder coil (10) passes through the maximum current under the regulation and control of the vehicle-mounted computer, so that the magnetic powder damper obtains the maximum damping force to prevent passengers from opening the vehicle door, and the safety of the passengers and pedestrians is further ensured;
fourthly, after the vehicle door is normally opened, the vehicle-mounted computer judges whether the passenger gets on or off the vehicle or opens or closes the door according to different door opening actions of the passenger, and the specific judgment method is as follows: when the pressure sensor A on the inner side of the inner handrail of the door senses the force, the passenger gets off and opens the door; when the pressure sensor B senses the force, the passenger gets on the vehicle and closes the door; when the pressure sensor C on the inner side of the outer handrail of the door senses the force, the passenger gets on the vehicle and opens the door; when the pressure sensor D at the outer side of the outer handrail of the vehicle door senses the force, the passenger gets off the vehicle and closes the door; when the high position pressure sensor E outside the door senses the force, the passenger gets off and closes the door;
fifthly, the vehicle-mounted computer linearly reduces the current passing through the magnetic powder linear coil (10) along with the increase of the induction force of each pressure sensor, so that the damping force of the magnetic powder damper is reduced, and the force required by opening and closing the vehicle door is further reduced;
sixthly, if the whole system detects that the passenger gets on or moves to threaten the safety of the passenger getting off when the passenger gets off and opens the door, the magnetic powder coil (10) in the magnetic powder damper passes through the maximum current under the regulation and control of the vehicle-mounted computer, so that the magnetic powder damper obtains the maximum damping force, the passenger is prevented from opening the door, and the safety of the passenger and the pedestrian is further ensured;
seventhly, when a passenger opens and closes the vehicle door, if the vehicle door is required to be kept at a certain opening degree, the pressure sensor at the corresponding position can not sense the pressure when the passenger leaves the armrest position, and the current in the magnetic powder coil (10) is immediately adjusted by the vehicle-mounted computer to be matched with the corresponding opening degree, so that the vehicle door is kept at the current opening degree stably;
eighthly, after the vehicle door keeps a certain opening degree, when the passenger opens and closes the vehicle door again, the corresponding position senses the pressure, the vehicle-mounted computer immediately reduces the current in the magnetic powder coil (10), and then the damping force of the limiter (12) is reduced, so that the vehicle door can be normally opened.
