Description
Technical field
The present invention relates to machinery field more particularly to a kind of anti-collision system for automobile.
Background technique
With the continuous development of science and technology, social materialss level is also continuously improved.Automobile is as a kind of conveniently traffic
Tool has entered the daily life of common people.But being continuously increased with automobile quantity, inevitably there is car accident not
Good fortune occurs, and causes the loss of life and property.
Traffic accident has become " the first in the world evil ", how to guarantee traffic safety, how to reduce the hair of relevant traffic accident
Raw rate and casualty rate have become the topic of whole society's concern.Security performance be Hyundai Motor important quality index it
One.How when automobile crashes, the safety of occupant is protected to the maximum extent, reduces the damage of automobile as each automobile
The direction that producer makes great efforts.When positive collision occurs for automobile, front anti-collision beam plays reduction enging cabin and occupant area is impaired, also can
Reduce the caused body structure damage of collision.
Ultrasonic wave, laser, infrared and microwave technology can be used to realize in automobile collision avoidance radar, but first three is easy to be disliked
The influence of bad weather and environmental factor is unable to ensure detection accuracy, thus attention concentration is placed on microwave thunder by domestic and international expert
Up to upper.
In intelligent transportation system, although automobile collision avoidance radar can promote vehicle safety performance, due at present not
The speed limit of specification driving behavior and vehicle is higher and higher, also not can avoid the automobile run at high speed and really collides, more
Add secondary accident caused by can not preventing other car accidents, for example, adjacent lane lorry blow out caused by side impact thing
Therefore.
Therefore, in the case where traffic accident is generally difficult to avoid, more then to consider when traffic accident occurs, to the greatest extent
The safety problem for possibly guaranteeing passengers inside the car guarantees that vehicle crew is usually directed to safely two aspects, and one is to guarantee vehicle occupant
Safety of the member in collision process, this respect mainly pass through bumper, air bag, the A column of vehicle body, intensity of B column etc.,
Another guarantees that the aspect of occupant's safety is then that can guarantee that occupant speeds away vehicle after collision generation as far as possible
Misfortune scene, avoids the generation of secondary accident.

Connecting rod described in root is parallel to each other, and one end is connected to the rear bumper, and it is hydraulic that the other end via spring is fixed on the centre
On piston on rear side of cylinder, the crossbeam is connected between the connecting rod.
It further include more hydraulic oil delivery pipes 8, voltage-controlled car door lock 9 in the present embodiment, every hydraulic oil delivery pipe is connected to
The side of intermediate hydraulic cylinder, extends at the door position of automobile, each voltage-controlled car door lock 9 and each hydraulic oil delivery pipe phase
Even, the end setting hydraulic stem of hydraulic oil delivery pipe is used as door lock drive rod, and door lock drive rod can drive voltage-controlled car door lock 9.
Existing car door lock is all one annular lock ring of setting on the vehicle frame of car door, then passes through the lock on car door
Locking of the lock ring realization to car door is fastened, although such car door lock can guarantee the secured locking of car door, once vehicle
When accident occurs, car door is because being squeezed and deformed frequent occurrence, and car door lock can not be opened, and causing occupant to be stuck in car can not escape
De- situation.
In response to this, one kind is present embodiments provided when accident occurs for vehicle, can be automatically opened, be avoided locking
And guarantee that car door will not thoroughly open the car door lock for losing protective effect.
Voltage-controlled car door lock 9 is set on the inside of the doorframe of car door comprising outer lock rings 91, inner lock rings 92, partition 93, detachable
Chain 94, interior lock pin 95, inner lock rings fixing seat 96, door lock drive rod are set to 95 inside of interior lock pin, fixation in parallel
Connection.
Outer lock rings 91 are as the lock ring on normal vehicle door lock, for realizing the lock of vehicle with the snap fit in car door
Tightly, outer lock rings are fixed on the side of partition 93, and inner lock rings 92, inner lock rings are fixed and (preferably rotatably fixed) in the partition other side
92 are set in inner lock rings fixing seat 96, and inner lock rings fixing seat is fixed in door frame, including upper and lower two part, have hollow
Through-hole, inner lock rings 92 are clipped between two parts up and down of inner lock rings fixing seat, and interior lock pin 95 passes through inner lock rings 92 and inner lock rings
Two parts up and down of fixing seat, inner lock rings 92 are fixed in inner lock rings fixing seat, the end of the inner lock rings 92 with it is removable
It unloads chain 94 to be fixedly connected, one end of the detachable chain 94 is fixedly connected with the inner lock rings 92, and the other end is fixed on institute
It states in door frame, for example, being fixed in the inner lock rings fixing seat side or door frame at other positions.Detachable chain with
Inner lock rings 92 are using detachable lock connection manually, and detachable lock chain length is no more than 12-20cm.Inner lock rings 92 are fixed
When in inner lock rings fixing seat, the outer surface of partition 93 is just concordant with door frame, to guarantee the planarization of door frame.
When vehicle breaks down, the connecting rod of front bumper or rear bumper is because being protruded into left and right hydraulic cylinder by shock
Interior, since bumper connecting rod is to the induced effect of its upper piston, can squeeze hydraulic oil makes hydraulic oil enter each hydraulic oil
In delivery pipe, initial setting up voltage-controlled valve between hydraulic oil delivery pipe and hydraulic cylinder, be initially in hydraulic oil delivery pipe vacuum (or
There is inert gas when initial in hydraulic oil delivery pipe), as the pressure of hydraulic oil increases, breaks through voltage-controlled valve and be injected into hydraulic oil
In delivery pipe, the door lock drive rod of end is driven, door lock drive rod moves upwards under the action of high pressure gas or hydraulic oil,
The interior lock pin 95 is driven to move upwards, so that inner lock rings are disengaged from inner lock rings fixing seat 96, since accident, accident occurs
Moderating process necessarily occurs for latter stage, car door (car door axle position is on front side of car door), and car door is with outer lock rings, partition and internal lock at this time
Ring is deviate under effect of inertia from door frame, automatic opening of the car door when accident occurs is realized, however, to ensure that vehicle occupant
The safety of member, car door can only be opened slightly, for example, slightly opening 3-12cm from car door locking state, car door is most of at this time
Through deviating from from doorframe, by detachable lock chain link between car door and door frame, guarantee that car door only opens a crack.Passenger is only
Car door escape can be opened by needing to open lock manually.Due to the present invention using Purely mechanical to opening at car door lock frame
Lock, is not limited by vehicle electric car door lock, even if interior electronic system collapse, still may be implemented to unlock.
It is highly preferred that detachable chain is fixed on the mode of door frame are as follows: it is fixed in door frame by lock, and
Beside passenger seat, on the inside of door frame, setting is directed to the manually opened handle of the lock, and passenger only needs pulling handle, so that it may
To realize that detachable chain and door frame disconnect, passenger is facilitated to open chain.The fixed form of this detachable chain is ability
Field technique personnel are easy to accomplish, can use any type of lock, for example have the annular lock of opening, interior handle
Annular lock rotation can be controlled, to discharge detachable chain.Here it is not described in detail.
