Background technology
In rolling stock standard EN14752-2015 " the body sidegate system of railway applications-rolling stock ", for as far as possible
Reduce the security risk of Train door towing personnel or object, it is specified that the requirement of anti-dragging.
The requirement of anti-dragging is simply proposed in EN14752-2015 standards, the detection outside in-car and car is not made will
Ask；But then need both to have reduced the security risk of Train door towing personnel or object in actual applications, and do not influence train
Normal operation.
Installation electron sensitive side is mainly to realize to barrier in the existing sealing strip of current track train-door system
For the purpose of detection, to detect as far as possible small barrier.The primary structure of existing sealing strip is typically inside and outside symmetrical, therefore is worked as
The barrier that can't detect, such as band are run into, no matter the electron sensitive side detected when being pulled from in-car side or outside is touched
The detection power of hair is essentially the same.The detection power is excessive, and the personnel on the outside of car may be caused injured because of barrier towing；Should
It is too small to detect power, in-car side may be caused to influence the normal operation of vehicle because barrier pulls.
In order to realize, passenger while dragged and injured risk due to that can also avoid due to in-car outside reduction car
Barrier pulls and influences train normal operation, it is necessary to which track vehicle door system is designed as to pull detection power outside in-car and car not
Together,, can with less power when being pulled from vehicle outside when having clamped the barrier that is not detected between sealing strip
It is detected, avoids outside towing injury to personnel；When being pulled from vehicle interior side, it is necessary to can be just detected using larger power
Arrive, the normal operation of vehicle can not be influenceed during inner side removal barrier.
The content of the invention
Goal of the invention：The invention provides a kind of door weather strip, the door weather strip can be being realized outside to in-car car
Cause that rail vehicle door detecting system is different to drag force detection sensitivity outside in-car car while sealing；From vehicle outside
It during towing, can be detected with less power, avoid outside towing injury to personnel；When being pulled from vehicle interior side,
Need to use larger power to be just detected, the normal operation of vehicle can not be influenceed during inner side removal barrier.
The content of the invention：A kind of door weather strip, side are mounting flange, the mounting flange shape and Train door sealing strip
It is identical that groove shape is installed；The opposite side relative with mounting flange is provided with raised and sealing lip, and sealing lip is arranged on the inner side of projection
Or outside, can also inside and outside both sides be respectively provided with sealing lip；Projection can ensure sealing strip entirety with sealing lip collective effect
Sealing, and can preferably detect barrier in door closing procedure；It is provided between raised and mounting flange and is used to electronics be installed
The cavity on sensitive side, cavity inner surface are designed with frictional resistance when lines is used for reducing the installation of electron sensitive side.
For the electron sensitive side installed in sealing strip, for the ease of detection, cavity all typically is set in the front end of adhesive tape
Installed；It is contemplated that may be excessively sensitive installed in the front end of adhesive tape, and cause in-car also easy detection trigger and
It is unsatisfactory for requiring；Therefore it is suitably rearmounted with cavity, i.e., projection is set in adhesive tape front end, set between raised and mounting flange empty
Chamber；There are two electrodes inside electron sensitive side, after two electrodes are contacted by external force extruding, send detection signal, electronics
Sensitive side have it is variously-shaped, so to be also configured as different shapes quick to install electronics of different shapes for the cavity of door weather strip
Feel side.
In anti-towing detection, when carrying out detection trigger for being clamped in the object towing among sealing strip, sealing strip exists
Deformation during towing is directive；Trend as pulled Direction distortion outside the oriented car of sealing strip outside car, in-car towing
The trend of oriented in-car Direction distortion；So in order to reach the difference of detection sensitivity outside in-car, then, it is outer identical big in the car
Under small drag force, the pressure of the electrode on electron sensitive side needs difference in the cavity deformable squeeze cavity in sealing strip, therefore needs
By electron sensitive side and raised installation site shifted relative.Specifically, by the sky for being provided with electron sensitive side on sealing strip
Chamber is not on same straight line with raised central axis shifted relative, i.e. central axis.When cavity and raised shifted relative,
Pulled in the car, outside car respectively, detection power when now electron sensitive side is triggered will be different.
Operation principle：A piece electron sensitive side is installed on to the raised side outside car of sealing strip of either side car door
In cavity so that electron sensitive side and raised shifted relative, when passenger pulls outward, because raised stress deformation extrudes sky
Chamber, cavity is caused to be deformed extruding electron sensitive side, electron sensitive frontier inspection measures the outer drag force of car and transmits a signal to driving
Room control centre, whether need to open the door by control centre's automatic decision；When passenger pulls inside, because raised stress deformation is drawn
Cavity is dragged, causes cavity to be deformed extruding electron sensitive side, electron sensitive frontier inspection measures in-car drag force and transmitted a signal to
Driver's cabin control centre, whether need to open the door by control centre's automatic decision；The triggering car door opening set due to control centre
Critical force it is identical, and in the car with when being pulled outside car due to pulling outside car when raised extruding cavity and in-car projection when pulling then
It is that the deflection for pulling cavity therefore cavity Comparatively speaking being pulled outside same drag force car can be more than and in-car pull cavity deflection；
Therefore it can realize that the in-car detection power that pulls pulls detection power more than car outside.
Beneficial effect：The present invention can be realized to in-car with being pulled outside car by changing the structure of original track door weather strip
The difference of power detection sensitivity；Door weather strip various structures provided by the present invention, it can need to use according to actual conditions
Different structure may be selected in different forms, considering cost and application effect.

In summary describe, door weather strip is specifically described in actual installation process in conjunction with above-mentioned door weather strip structure
In mounting means：
The first mounting means:
During in order that must be pulled from vehicle outside, it can be detected with less power, be dragged when from vehicle interior side
, it is necessary to can be just detected using larger power when draging, as shown in figs. 5 or 7, when projection biases, installation method is as follows：
1st, by the cavity 2 of the 7 installed therein door weather strips in electron sensitive side, electron sensitive side 7 and projection 3
Shifted relative, the mounting flange 1 of the door weather strip is arranged in the sealing strip installation groove on car door；Projection 3 is close to dress
There is the side of the cavity 2 on electron sensitive side 7 towards door outside；
2nd, the sealing strip being arranged on the mounting flange 1 of the door weather strip of another same shape on opposite side car door is pacified
Fill in groove, two door weather strips are in a center of symmetry.
For projection do not bias and cavity bias in the case of, as shown in fig. 6, be fitted without projection opposite side door sealing
Bar is designed with corresponding depression thereon, and projection 3, which can just be inserted, forms sealing in depression.
Second of mounting means
For the door weather strip of projection biasing, the mounting means on its electron sensitive side 7 can be with the first mounting means
Electron sensitive side 7 is mounted in the cavity 2 of the door weather strip of difference, i.e. both sides, then the electron sensitive side 7 of both sides is equal
Need to be separately mounted to that each in the cavity 2 of raised 3 side outside car door, electron sensitive is installed compared to only side
The situation on side 7, the difference of the in-car outer detection trigger force of this kind of installation method can be bigger, i.e. the detection meeting to drag force outside car
It is sensitiveer.This kind of installation method can also make the side for being fitted without electron sensitive side 7 originally, it is easier to be detected.It is false
Such as only there is a sensitive side in left side, and left direction detection power is if it is 70, and it is probably 100 to detect power to the right, in satisfactory model
In enclosing；But if there is sensitive side both sides, the power that may be detected to the left is 70, it is probably 80 or 60 to detect power to the right.Thus
It can be seen that the sensitive side on the right side of increase, the sensitive frontier inspection dynamometry in left side does not have too big change, but enables to right side to detect
Power and left side detection power are more nearly, i.e., no matter in car door homonymy pull car door to the left or to the right, its detection sensitivity phase
Closely so that control centre can more accurately judge dragging situation, and it is critical to unify drag force when setting is emergent to open the door
Value.
In summary, for the present invention, cavity is finally electric in cavity in order to realize in fact with raised shifted relative
The sensitive side 7 of son and raised shifted relative, the different purpose of critical force is detected outside in-car so as to reach, therefore for cavity and projection
Relative position be not limited to only above-mentioned embodiment, it is any so that electron sensitive side 7 and external force part are as raised
The embodiment of shifted relative should all belong within protection scope of the present invention.
