The solution having been proposed that in view of the foregoing and by prior art, the task of the present invention is in that, structurally so reduces finger and squeezes the danger on the pair closing seamed edge swinging plug door, enabling eliminates pair and close the broad gap between seamed edge and door frame.
Solve the system of this task should constitute as simply as possible and be safeguard close friend simultaneously.
This task utilizes a kind of for closing the anti-device solution clamping and sealing swing plug door on seamed edge in pair according to the present invention.According to the theme that the advantageous extension configuration of assembly of the invention is other subordinate scheme.
The present invention relates to and a kind of anti-on seamed edge clamp and seal vehicle and swing the device of plug door for closing in pair, this pair closing seamed edge seamed edge extended from bottom to top with doorway under the closed mode of door is opposite, and this device has:
Ground, side pair close that seamed edge extends from bottom to top, for detecting the sensor element clamped, and
It is additionally provided on potted component inside sensor element, that extend from bottom to top,
Wherein, sensor element and potted component are separated from each other.
One vital idea of the present invention is in that, the pair closing seamed edge swinging plug door is provided with sensing device and thus produces the active control of door motion.
Another vital idea of the present invention is in that, the sensor element of door and potted component are the elements being separated from each other.The advantage of this structure will be described further below.
By arranging the sensor element extended from bottom to top with closing seamed edge side to the pair swinging plug door, reach advantages below:
If 1. passenger starts to catch before the pair of the door opened to close seamed edge at the closing process (running also referred to as closing) of door, then the operation of closing of door is prevented from due to the detection of sensor element.
If passenger close run start after catch the pair of door of closedown close seamed edge or close run time object or limbs be in secondary closing between seamed edge and doorway, then this door makes its closing process reverse and reopen.
Stop possible injury/extruding in both cases, because the door leaf swinging plug door is prevented from cutting out and therefore not up to the danger position of the door cut out.
It is applicable to all of swing plug door according to assembly of the invention, but is particularly suitable for bus and rail vehicle, for instance low vehicle frame bus, shuttle train and low vehicle frame tramcar.
As mentioned, sensor element is closed in pair from bottom to top and is extended on the side of seamed edge.Secondary seamed edge of closing is usually the seamed edge extended in vertical direction point-blank.But secondary seamed edge of closing according to the structure of door can also upwardly extend in the side being different from vertical line and/or bend point-blank.Sensor element preferably extends in the whole length of seamed edge and form to sense lath is constituted without interruptedly closing in pair.It is also conceivable that the secondary regional closing seamed edge is provided with sensor element, say, that use the sensor element interrupted, as long as still meeting above-mentioned security function.
Sensor element is elastically deformable in one embodiment of the invention.From there through sensor, controlling device for doors is additionally realized preventing clamping or prevent injury.
The pressure-loaded that pair is preferably closed on seamed edge by sensor element converts the signal of telecommunication to.Pressure-loaded is produced by the extruding of sensor element, for instance when sensor element is caught by passenger or when in closing process, object or limbs are in secondary closing between seamed edge and doorway.
In another embodiment of sensor element, sensor element includes housing and at least one cavity of being fixed on door leaf.This housing is preferably made up of elastomeric material, and it can be compressed when loading from external pressure, but again recovers its original-shape when lax.The housing of sensor element can be such as the elastic section bar being plugged on door leaf.This section bar can pass through extrusion process or coextrusion technique manufacture and constitute as hollow profile.
Cavity in the housing of sensor element can contain such as air according to a kind of embodiment, it will be preferred that compression air, thus sensor element is constituted as pneumatic transmitter.When pneumatic transmitter, outside pressure-loaded causes that the pressure in cavity changes, and this pressure variation is as being converted into the signal of telecommunication by triggering to pressure-sensitive switch.Signal is sent to controlling device for doors, and then the latter stops or the closedown of interrupt gate runs.
In the another kind embodiment more preferably of sensor element, the cavity in sensor element housing contains electric switch lath.Electric switch lath advantage compared with pneumatic transmitter is, it triggers in performance seldom by the impact of temperature fluctuation at it.So even still can carry out the active monitoring and protection extruded when temperature fluctuation is bigger.
Electric switch lath can so be constituted so that it includes two conductive strips arranged by an insulator dielectric.Under executing stressed situation from the outside, for instance when the hands of object or passenger is jammed, two conductive strips are got together and therefore trigger electrical contact, and this electrical contact discharges the signal of telecommunication from it over there.Therefore passing the signal to controlling device for doors, then this controlling device for doors stops or the closedown of interrupt gate runs.Such electric switch lath is by prior art, such as open by EP1561623A2.
In the another kind of scheme of the present invention, except the pressure-loaded that sensor element acts on from the outside, also monitor and analyze the current of electric of the motor of door and/or the time of the closing process of door.If the pre-specification of current of electric and/or this time and permission or expected value crosses existing deviation, then same impeding shutdown process or reopen door.This additional monitoring is also referred to as " fail safe (FailSafe) ".
Other sensor plans be such as there is the sensor of light emitting diode, according to the sensor of change of the sensor of grating principle work and/or detection reflection light or radiation.
Except sensing function, sensor element can also apply anti-pollution and prevent the pair at door from closing the defencive function of collision on seamed edge.If sensor element is such as gum elastic section bar, then except sensing function, it is applied simultaneously to the function of the secondary protection rubber closed on seamed edge.
In one embodiment of the invention, sensor element is arranged in this wise so that leave gap between the seamed edge extended from bottom to top and the sensor element on doorway under the closed mode swinging plug door.This gap is kept as little as far as possible, is especially less than finger width, to avoid the moulding shortcoming of broad gap in prior art.
In one in the selectable embodiment of aforementioned embodiments, sensor element is so arranged so that under the closed mode swinging plug door, the seamed edge extended from bottom to top on doorway and sensor element seamlessly close.Structure is constituted in this wise in this case so that the pressure not triggering unexpected door opening signal acts on sensor element.Being acceptable lower than the pressure of sensor element activation threshold value, wherein, sensor element can also close the additional seal assemblies use between seamed edge and doorway seamed edge as pair in this case.This sealing function of sensor element such as provides when sensor element includes the elastic construction of such as rubber.This sealing function of sensor element is with the sealing function according to the present invention independently and the potted component that exists dividually of sensor element.
In the another kind of scheme according to assembly of the invention, swing the door leaf of plug door and be made up of at least two element and sensor element is additionally constituted as the potted component in gap sealed between two elements of door leaf.The door leaf swinging plug door such as can multilamellar be constituted.Then the intermediate space existed between the different layers of door is covered on the side that pair closes seamed edge by sensor element and seals.
As already mentioned above, the potted component separated with sensor element is also included according to assembly of the invention.The advantage of this device is in that, only needs when maintenance or fault to change an element.Particularly when potted component is damaged or worn out, it is not necessary to change generally more expensive but unspoiled sensor element simultaneously.
What sensor element and potted component separated another advantage is that, sensor element and potted component can be made up of special and that function is adaptive different materials easily.In whole implementation mode, namely in the sensor-seal element of combination, different materials it is hard for manufacturing.The housing of sensor element and potted component can be such as the section bars of extruding.If selecting material two kinds different and sensor-seal element to be made up of a block, then coextrusion device must be used during fabrication.According in assembly of the invention, contrary two parts can be made up of different materials and can separately extrude, and this simplify processing.
Potted component is arranged on the secondary side closing seamed edge with extending from bottom to top.The such combined effect of seamed edge on this potted component and doorway so that prevent air-flow from passing through the gap between the seamed edge on doorway and the pair closing seamed edge of door and enter in vehicle or discharge in vehicle.The inner side of sensor element so it is arranged on so that its pair sealing doorway and door closes the gap extended from bottom to top between seamed edge for this potted component.Potted component is preferably elastic and can move on two sides.In one embodiment of the invention, potted component is made up of the section bar extruded.Potted component can (the closed mode lower seal element at door abuts on this sealing surface) bending on the direction of potted component.It is bent upwards in the side of sealing surface it is meant that potted component upwards becomes increasingly less angle with the vertical wire clamp of sealing surface in its walking on sealing surface.Thus under the closed mode of door, it is achieved that the raising of potted component thrust on the sealing surface on doorway.Potted component itself can also deform when low deformability, and its mode is curature variation, and thereby compensates for the machining tolerance owing to variations in temperature causes and size fluctuation.
Potted component not necessarily have to have air chamber as sealing device illustrated in DE20311653U1.Therefore can not have completely potted component pressure-loaded realize potted component compression on the sealing surface on doorway.The total thus including the miscellaneous part of sensing device becomes the simpler and more difficult impact being subject to temperature fluctuation.
As already mentioned, sensor element and potted component can be made up of the different materials adaptive specially with respective function.
The housing of sensor element is such as made up of elastomer or elastic thermoplastic, and it can harden and usually contain fire retardant.Sensor element and/or potted component are advantageously made up of the material mainly with resistance to UV radiation and/or chemically-resistant impact, preferred oil resistant.Resistance to UV radiation can be passed through carbon black-filled or carbon nano-fiber material and realize.
