Description

  INDUSTRIAL APPLICABILITY The present invention is mounted in a range in which a flange cannot be set, such as the upper and lower parts of a sliding door that moves forward and backward of a vehicle body such as a wagon car, a one-box car, and a sedan car, and when a sliding door is closed, limbs, TECHNICAL FIELD The present invention relates to a method for manufacturing an end portion of a weatherstrip with a sensor for detecting that an object is sandwiched and an end structure of the weatherstrip with a sensor.

  As shown in FIG. 10, when the slide door 100 is closed, limbs and the like are formed on the front end surface of the slide door 100 that moves forward and backward of the vehicle body such as a wagon car, a one-box car and a sedan car. There is known a weather strip 10 with a sensor for detecting that the weather strip 10 is sandwiched between the weather strip 10 and the body B, which will be described later.

As shown in FIG. 11, the sensor-equipped weather strip 10 has a sensor S on the top of the mounting base 11 having a substantially U-shaped cross section, that is, on the outside of the connecting wall 11c that connects the first side wall 11a and the second side wall 11b. The tubular portion 12 having the hollow portion 12b to be housed is integrally molded, and when fixed to the flange 101 formed on the slide door 100, it is provided inside the attachment base portion 11 having a substantially U-shaped cross section. A method of fixing using the reaction force of the claw-shaped portion 14 is generally known.
A channel portion 13 having a C-shaped cross section is provided outside the second side wall 11b of the mounting base portion 11, and is used to hold a wire harness (not shown) connected to the sensor S to be inserted later. It Further, a parting portion sealing lip 15 is provided so as to project from the outside of the first side wall 11a. A core material 16 having a substantially U-shaped cross section is embedded in the mounting base 11.

  There is a strong demand for such a weather strip 10 with a sensor to extend in the vertical direction as much as possible in order to make the detection range as wide as possible, but in the case of a vehicle body as shown in FIG. Due to a large opening or the like, as shown in FIG. 12, there is a range L in which the flange 101 cannot be set due to vehicle design restrictions, such as the upper portion X or the lower portion Y of the slide door 100.

In such a range L where the flange 101 cannot be set, it is common practice to fix the end portion of the weather strip 10 by fixing it through a clip or a double-sided tape. The area attached to the range L is not manufactured only by the mold forming part for the reason of maintaining a constant value, but the range L is formed as the mold forming part by molding the end part of the extruded cylinder part. It may then have to consist of a protruding extrusion.
However, in this case, a special structure for fixing the molding portion and the extrusion molding portion in the range L and fastening them to the vehicle is also required.
Further, when the region attached to the range L is not linear but curved (normally, it has a linear shape), the core of the die to be inserted into the extruded tubular portion is formed after the die is formed. There is also a problem that it cannot be pulled out.

  On the other hand, a method is known in which an end portion of a weather strip is fixed to an area L in which the flange 101 cannot be set by using an insert made of a metal plate such as stainless steel and having a portion having a substantially L-shaped cross section. (Patent Document 1).

  Symbols in parentheses indicate corresponding elements or corresponding matters described in the drawings and modes for carrying out the invention described later.

According to the present invention, in manufacturing the end portion of the weather strip with the sensor, the flange formed on the door of the automobile is attached to the interrupted space portion, and the sensor for detecting foreign matter is housed in the tubular portion having the hollow portion. Since the mounting base is cut off so that the already formed tubular portion is projected so as to extend linearly and remains, it is not necessary to newly manufacture the tubular portion by molding.
Therefore, as shown in the conventional example (Patent Document 1), a space for removing the core of the mold is not required, and therefore, the shape of the tubular portion does not need to be particularly large, and is inserted into the tubular portion thereafter. The sensor can be held in a stable state.
Further, since the tubular portion is left so as to extend linearly and is molded together with the fixing plate in that state, the core inserted in the tubular portion can be easily extracted. The fixed plate can also be formed into a desired curved surface by molding.

Since the sensor is inserted into the linearly extending cylindrical portion from the other end of the weather strip after the molding, the insertion is extremely easy.
The fixed plate, since it is molded as is curved so as to increase the separation gradually from the tip is connected to one end of the extruded tubular section, after insertion of the sensor, curved Move the fixed plate so that it is parallel to the tubular part, and connect the lower surface of the tubular part and the upper surface of the fixed plate with, for example, double-sided tape, etc. to stabilize in the space part where the flange formed on the door of the car is broken.

Even if the shapes of the door openings facing each other are such that, for example, the portion facing the mounting base has a deep recess and the portion facing the linearly extending cylinder has a shallow recess, It can be arranged without any particular deformation.
As a result, it is possible to widen the detection range of the sensor that is inserted into the cylindrical portion later.

Further, according to the present invention, the lateral width of the portion of the fixing plate along the attachment base portion is gradually changed from the width substantially the same as the attachment base width to the width substantially the same as the outer diameter of the linearly extending cylindrical portion. Because it has been made, there is no step and it looks good.

  Further, according to the present invention, since the thickness of the neck portion is made thicker than the wall thickness of the cylindrical portion, it is possible to stably make a notch in a long range when cutting the attachment base portion by a predetermined distance in the longitudinal direction. Therefore, for example, it is possible to prevent the core material from being exposed or the tubular portion being damaged by the notch when the core material is embedded in the attachment base portion.

An end part manufacturing method of a weather strip with a sensor and an end part structure of a weather strip with a sensor according to an embodiment of the present invention will be described with reference to the drawings.
As shown in FIGS. 10 and 12, a method for manufacturing an edge portion of a weather strip with a sensor according to an embodiment of the present invention is, as shown in FIGS. This is mainly related to an end structure of a weather strip with a sensor attached to a space M where the flange 101 is interrupted in a range L in which the flange 101 cannot be set in the upper part X of 100 (the same applies to the structure of the lower part Y). , Cutting process, mold forming process, sensor insertion process. It is also possible to add a bonding step to this.
Then, in the weather strip 10 with the sensor, when a foreign object such as a part of a human body (finger or limb) is sandwiched between the slide door 100 and the door opening on the body B side shown in FIGS. 6 and 7. A cylindrical portion 12 in which a sensor (pressure-sensitive sensor) S that outputs a corresponding signal and detects the presence of a foreign substance is housed is integrally molded on the top of a mounting base 11 having a substantially U-shaped cross section through a neck 17. It will be done.

When the mounting base 11 is mounted in front of the slide door 100 (in the front direction of the vehicle), the first side wall 11 a located outside the slide door 100 and the second side wall located inside the slide door 100. 11b, a connecting wall 11c that connects the first side wall 11a and the second side wall 11b, and two claw-shaped portions 14 and 14 project from the inside (inside the vehicle) of the second side wall 11b. From the outside (inside the vehicle), a parting portion sealing lip 15 is provided so as to project.
Further, a channel portion 13 having a C-shaped cross section is provided outside the second side wall 11b of the mounting base 11 (outside the vehicle), and is connected to a sensor S to be inserted into the tubular portion 12 later (a wire harness shown in the drawing). Not used) to hold. Note that the cross-sectional shape of the channel portion 13 is not limited to the C-shaped cross-section, and may be any one that holds a wire harness. Also, the channel part can be omitted. Further, a core material 16 having a substantially U-shaped cross section is embedded in the mounting base 11.

  The tubular portion 12 is a tubular body that extends in the up-down direction and is provided so as to project from the connecting wall 11c of the mounting base portion 11 via the neck portion 17 toward the front of the slide door 100 (the vehicle front direction).

  The mounting base 11, the cylindrical portion 12, the channel portion 13, the claw-shaped portion 14, and the parting portion sealing lip 15 are extruded from a rubber-like elastic body made of a synthetic rubber such as EPDM or a thermoplastic elastomer such as TPO or TPS. The sliding door 100 is fixed to the flange 101 formed on the sliding door 100 by using the reaction force of the claw-shaped portion 14.

  In this manner, the weather strip 10 with the sensor formed by extrusion is attached as it is at the portion where the flange 101 is formed on the slide door 100, but in the space portion M where the flange 101 is interrupted, the weather strip with the sensor is attached according to the following steps. The ends of the weather strip 10 are manufactured.

(1) Excision Step First, in the excision step, as shown in FIG. 1, the attachment base 11 of the weather strip 10 with a sensor is excised by a predetermined distance T in the longitudinal direction, and the cylindrical portion 12 is projected so as to extend linearly. Let me leave. The weather strip 10 with a sensor shown in FIG. 1 is extruded.
Here, the predetermined distance T is 160 mm. Further, the wall thickness of the cylindrical portion 12 is 1 mm.
Further, even if the cut line between the mounting base 11 and the tubular portion 12, that is, the cut line of the neck portion 17 is a horizontal plane cut as shown in FIG. 1 and FIG. 8 (a), the central projection as shown in FIG. 8 (b). It may be cut. Further, although the cut surface of the attachment base portion 11 is cut perpendicularly to the extending direction of the tubular portion 12, it may be cut obliquely.

(2) Mold Forming Step Next, in the mold forming step, one end of the weather strip 10 from which the mounting base 11 has been cut off is fixed to a mold (not shown) by the cutting step, and as shown in FIG. The fixing plate 20 is molded with a molding material so that the one end (tip) 12a of the tubular portion 12 is connected to the one end.
Fixed plate 20, as shown in FIG. 5 is a cross section substantially L-shaped comprising a vertical portion 20a and a horizontal portion 20b, one end of the cylindrical portion 12 from the (front end) 12a progressively toward the end face side of the mounting base portion 11 It is curved so as to be largely separated.
That is, the fixed plate 20 is molded in a state in which the portion connected to the one end (tip) 12a of the tubular portion 12 is used as a fulcrum and the other end side is rotated so as to be separated from the mounting base 11. After molding, the linearly extending cylindrical portion 12 and the mounting base portion 11 are rotated in opposite directions (clockwise in FIG. 3) so as to follow the curved upper surface 20d of the vertical portion 20a of the fixed plate 20. Can be moved to. Before moving, a double-sided tape 30 is attached to the lower surface of the linearly extending cylindrical portion 12, that is, the lower surface of the cylindrical portion 12 which is cut in a horizontal plane, as shown in FIG. Painted). Further, although not shown, the double-sided tape 30 may be attached along the curved upper surface 20d of the vertical portion 20a of the fixed plate 20 instead of being attached to the lower surface of the tubular portion 20.

The vertical portion 20a is a portion along the attachment base portion 11, and as shown in FIG. 5, its lateral width 20W is substantially the same as the outer diameter 12D of the linearly extending cylindrical portion 12. Further, an insert 21 is embedded in the vertical portion 20a, and a part of the insert 21 is projected from the other end of the vertical portion 20a of the fixing plate 20 as shown in FIGS. A protrusion 21b extending in the longitudinal direction of the weather strip 10 is formed on 21a.
Further, the upper surface of the vertical portion 20a is horizontal as shown in FIGS. 5 and 8A, but when the cylindrical portion 12 side is formed as a central protruding cut as shown in FIG. A central concave shape that receives the central protruding cut. In addition, as shown in FIG. 2, a cylindrical portion 20c having substantially the same outer diameter as the outer diameter 12D of the tubular portion 12 is formed in front of the upper surface of the vertical portion 20a, and one end portion 12a of the tubular portion 12 is provided from the other end portion. It can be inserted and positioned.
A hole H through which a clip portion C separate from the fixed plate 20 penetrates is formed in front of the vertical portion 20a and in front of and behind the horizontal portion 20b, and the clip portion C is attached to the hole H in advance. .
Here, the horizontal width 20W of the vertical portion 20a is 6 mm. Similarly, the outer diameter 12D of the tubular portion 12 is also 6 mm. The width 11W of the mounting base 11 is 12 mm.

(3) Sensor Inserting Step Then, in the sensor inserting step, the sensor S is inserted into the tubular portion 12 from the other end portion of the weather strip 10 as shown in FIG. 2 after the mold forming step. At this time, since the cylindrical portion 12 extends linearly, the sensor S can be inserted easily and quickly.
Also, after inserting the sensor S. Further, the tip of the cylindrical portion 20c formed in front of the upper surface of the vertical portion 20a is sealed with butyl rubber or the like.

  In this state, the end structure of the weather strip 10 with a sensor before being attached to the slide door 100 is completed.

(4) Adhesion Step When the weather strip 10 with the sensor is attached to the slide door 100, the adhesion step is performed. In this bonding step, as shown in FIG. 3, the tubular portion 12 and the mounting base portion 11 that linearly extend with the curved fixed plate 20 tip 20c as a fulcrum are rotationally moved, and the lower surface of the tubular portion 12 and the upper surface of the fixed plate 20 are moved. 20d is connected via the double-sided tape 30. At this time, the protrusion 21b formed on the protrusion 21a of the insert 21 protruding from the other end (rear) of the fixed plate 20 is fitted into the recess 19 of the mounting base 11, and at the same time, the other end is also bonded. . The fixed plate 20 is attached to the space portion M where the flange 101 of the slide door 100 is interrupted by the clip C which is attached in advance.

As described above, the flange 101 formed on the sliding door 100 of the automobile is attached to the interrupted space M, and the sensor S for detecting a foreign substance is housed in the tubular portion 12 having the hollow portion 12b. In manufacturing the end portion, the tubular portion 12 is already extruded (note that it is possible to mold the portion shown in FIG. 1 which is rarely formed in advance but is formed in advance in advance). Since the mounting base portion 11 is cut off so as to be projected and left so as to extend linearly, it is not necessary to newly manufacture the tubular portion 12 by die molding.
Therefore, as shown in the conventional example (Patent Document 1), the space for removing the core (not shown) of the mold becomes unnecessary, so that it is not necessary to particularly increase the shape of the cylindrical portion 12, and the cylindrical portion 12 After that, the inserted sensor S can be held in a stable state.
Further, since the tubular portion 12 is left so as to extend linearly and is molded together with the fixed plate 20 in that state, the core inserted into the tubular portion 12 can be easily extracted. The fixed plate 20 can also be formed into a desired curved surface by molding.

Since the sensor S is inserted into the linearly extending cylindrical portion 12 from the other end of the weather strip 10 after molding, the insertion is extremely easy.
The fixed plate 20, so as is curved is molded so as to increase the separation from the tip 12a is connected to the distal end 12a of the cylindrical portion 12 gradually, after insertion of the sensor S, linear The cylindrical portion 12 and the mounting base 11 extending in the direction of the fixed plate 20 are rotationally moved along the curved upper surface 20d of the vertical portion 20a of the fixed plate 20 to move the lower surface of the cylindrical portion 12 and the upper surface 20d of the fixed plate 20. By connecting with the double-sided tape 30, the flange 101 formed on the slide door 100 can be stably attached to the space M where the flange 101 is interrupted.

  Further, since the projection 21b formed on the projection 21a of the insert 21 embedded in the fixing plate 20 is fitted into the recess 19 of the mounting base 11, the mounting base 11 can be fixed easily and firmly. It is also possible to perform positioning when fixing the mounting base 11.

In the present embodiment, the horizontal width 20W of the vertical portion 20a of the fixed plate 20 is set to be substantially the same as the outer diameter 12D of the linearly extending cylindrical portion 12, but is set to be substantially the same width as the horizontal width 11W of the mounting base 11. Alternatively, the width may be gradually changed from a width substantially the same as the lateral width 11W of the mounting base 11 to a width substantially the same as the outer diameter 12D of the tubular portion 12.
However, if the horizontal width 20W of the vertical portion 20a of the fixed plate 20 is set to be substantially the same as the outer diameter 12D of the linearly extending cylindrical portion 12, as shown in FIG. In the case of a vehicle body having a deep-drawing portion Ba with a deep recess and a shallow-drawing portion Bb with a shallow recess as the shape on the body B side that is the door opening facing the slide door 100 on which the There is a problem that the weather strip 10 with the sensor interferes with the door opening B when the door is closed. Therefore, a portion facing the mounting base 11 which is a wide portion is arranged in a deep drawing portion Ba having a deep recess, and a portion facing the linearly extending cylindrical portion 12 which is a narrow portion has a shallow recess. If the fixed plate 20 is arranged in the diaphragm portion Bb, the fixed plate 20 can be arranged without being particularly deformed, and the detection range by the sensor S that is inserted into the cylindrical portion 12 having the hollow portion 12b later can be widened. .

Further, as shown in FIG. 9, the thickness 17L of the neck portion 17 provided between the mounting base 11 and the tubular portion 12 may be 2 mm or more (here, 2 mm) thicker than the wall thickness 12L of the tubular portion 12. According to this, when cutting the attachment base 11 in the longitudinal direction, a notch in a long range can be stably performed. Therefore, it is possible to prevent the core material 16 embedded in the mounting base portion 11 from being exposed by the notch or damaging the tubular portion 12.
Alternatively, the parting portion sealing lip 15 may not be provided.

Further, in the present embodiment, the cylindrical portion 12 having the hollow portion 12b into which the sensor S is inserted later is formed integrally with the mounting base portion 11 in the sliding door 100. However, the tubular portion 12 that functions as a sealing material that elastically contacts the door opening side may be integrally formed with the mounting base portion 11 having a substantially U-shaped cross section, and may be a flange in a side door or a back door. Anything can be applied as long as 101 is attached to the discontinuous space M.
According to this, the end portion of the weather strip 10 extruded can be installed extending from the portion where the flange 101 exists, so that the shape and sealing pressure of the tubular portion 12 of the weather strip 10 can be made substantially uniform. be able to.
