Description

  The present invention relates to a protector with a touch sensor.

  In Patent Document 1, an outer shell having a space portion on the inner peripheral side, two conductive portions provided via the space portion on the inner peripheral side edge of the outer shell, a core wire embedded in each conductive portion, and a core wire A sensored protector comprising a connected control device is disclosed. The protector with a sensor described in Patent Literature 1 is attached, for example, so as to protrude toward the front side of the vehicle body on the front end surface of the slide door. And, for example, when a foreign object such as a user's hand or a finger is sandwiched between the front end surface of the slide door and the body side opening facing the front end surface, the outer shell is compressed and deformed, so that the two conductive portions Short-circuit each other. When the two conductive parts are short-circuited, a change in the electrical signal is transmitted to the control device by the core wire embedded in each conductive part. Thus, the protector with a sensor detects a foreign object being caught.

Japanese Patent Laying-Open No. 2015-174633

  By the way, in a state where the protector with a sensor as described in Patent Document 1 is attached to the vehicle, the outer shell is usually exposed from the vehicle. For this reason, there is a possibility that the outer shell may be broken by being pulled by a sharp object such as a key carried by the user. When the outer shell is torn, there is a possibility that the two conductive portions are short-circuited due to the liquid entering the hollow portion from the portion where the outer shell is torn. In this case, the control device erroneously detects the presence of the foreign matter even though the foreign matter is not caught.

  Accordingly, an object of the present invention is to provide a protector with a touch sensor with improved durability.

  A protector with a touch sensor that solves the above problems is a protector with a touch sensor provided at the periphery of an opening provided in a vehicle or the periphery of an opening / closing body that opens and closes the opening, and an inner shell having a space portion therein, An outer shell covering the inner shell, and two conductors that are provided in the inner shell through the space portion and come into contact with each other when the inner shell is compressed and deformed by sandwiching foreign matter.

  According to the said structure, even if it is a case where an outer shell is torn by external force, it can suppress that a liquid etc. permeate into the space part which an inner shell has inside. For this reason, it is possible to prevent the two conductors from being short-circuited even though no foreign matter is caught. That is, erroneous detection of foreign matters can be suppressed.

  In the above protector with a touch sensor, the inner shell preferably has a protective layer covering the two conductors.

  According to the above configuration, the durability of the inner shell is improved. For this reason, the erroneous detection of the foreign material by liquid etc. infiltrating into the space part which an inner shell has inside can further be suppressed.

  In the above protector with a touch sensor, the visual aspect of the surface in the inner contour is preferably different from the visual aspect of the surface in the outer contour.

  According to the said structure, when an outer shell is torn, it becomes easy for a user to visually recognize the inner shell exposed from the location where the outer shell was torn. As a result, the outer shell that the user has torn can be repaired at an early stage.

  In the above protector with a touch sensor, it is preferable that the surface color of the inner shell is different from the surface color of the outer shell.

  According to the said structure, it can make it easy to visually recognize that the outline was torn by the simple structure.

The figure which shows the state by which the outline of the protector with a touch sensor was torn. The figure which shows the modification of a protector with a touch sensor. The elements on larger scale which show the modification of a protector with a touch sensor.

  Hereinafter, an embodiment of the protector with a touch sensor of the present invention will be described. The protector with a touch sensor of this embodiment is attached to a slide door, for example.

  As shown in FIG. 1, the vehicle 1 includes a slide door 20 as an “opening / closing body” that opens and closes an opening 10 a formed on a side surface of the vehicle main body 10, and foreign objects are sandwiched between the opening 10 a and the slide door 20. And a protector 30 with a touch sensor to detect.

  The slide door 20 includes a driving device 21 having an electric driving force by a motor (not shown) and a control device 22 that controls the driving device 21. The slide door 20 functions as a so-called power slide door that is operated in the vehicle front-rear direction by the electric driving force of the drive device 21. Specifically, the sliding door 20 is closed to the vehicle front side by the driving device 21 controlled by the control device 22 to close the opening 10a. The slide door 20 is opened to the vehicle rear side by the drive device 21 controlled by the control device 22 to open the opening 10a. The user of the vehicle 1 can get on and off the vehicle 1 by opening the opening 10a.

  Further, a protector 30 with a touch sensor, which will be described later, is connected to the control device 22 via a lead wire 23. In the state where the sliding door 20 is closed, if a foreign object such as a human hand or a finger is caught between the opening 10a and the sliding door 20, the controller 22 causes the protector 30 with a touch sensor to remove the foreign object. Detect pinching. And the control apparatus 22 will change the closing operation | movement of the slide door 20 into an opening operation, if the pinching of a foreign material is detected.

  The protector 30 with a touch sensor is attached to the vehicle 1 so as to extend in the vehicle height direction at the front end of the slide door 20.

  Here, the configuration of the protector with touch sensor 30 will be described in detail with reference to a cross-sectional view taken along line AA of the protector with touch sensor 30 shown in FIG.

  As shown in FIG. 2, the protector 30 with a touch sensor includes an attachment portion 31 for attachment to the slide door 20, an inner shell 32 having a space G inside, an outer shell 33 covering the inner shell 32, and an inner shell 32, two conductors 34 provided via the space G, and a core wire 35 embedded in each conductor 34.

  The attachment portion 31 includes a vehicle inner side wall 31a, a vehicle outer side wall 31b, and a connecting wall 31c that connects the vehicle inner side wall 31a and the vehicle outer side wall 31b. The mounting portion 31 has a substantially U-shaped cross section including a vehicle inner side wall 31a, a vehicle outer side wall 31b, and a connecting wall 31c when viewed from the vehicle height direction. The flange 20a formed at the front end is sandwiched.

  The attachment portion 31 includes two holding lips 31d extending from the vehicle inner side wall 31a toward the vehicle outer side wall 31b, a decorative lip 31e extending from the tip of the vehicle outer side wall 31b, and the attachment portion 31. And a substantially U-shaped core material 311 embedded along. The distance from the front end of the holding lip 31d to the vehicle outer side wall 31b is shorter than the thickness of the flange 20a of the slide door 20 in the vehicle width direction. On the other hand, the movement of the vehicle inner side wall 31a and the vehicle outer side wall 31b in the vehicle width direction is restricted by the core material 311. For this reason, the two holding lips 31d are elastically deformed inward of the vehicle in a state where the attachment portion 31 holds the flange 20a. And the attachment part 31 is comprised so that the flange 20a of the slide door 20 may be clamped more firmly by the restoring force of the holding lip 31d which has been elastically deformed.

  The inner shell 32 is molded by an insulating rubber material so as to protrude from the mounting portion 31 to the vehicle front side. In the present embodiment, the inner shell 32 has a substantially U-shaped cross section as shown in FIG. A white fluorescent color paint is applied to the surface 32 a of the inner shell 32.

  The inner shell 32 has leg portions 321 that sandwich the space portion G in a direction orthogonal to the opening / closing direction (vehicle longitudinal direction) of the slide door 20. The leg portion 321 extends in the opening / closing direction (vehicle longitudinal direction) of the slide door 20. When a compressive load is applied to the inner shell 32 due to the foreign object being caught, the thickness of the leg portion 321 is set to such an extent that the leg portion 321 of the inner shell 32 is first compressed and deformed.

  Further, as shown in FIGS. 4 and 5, a metal layer 36 as a “protective layer” may be embedded in the inner shell 32. The metal layer 36 is made of a metal material having a higher strength than the material constituting the inner shell 32. Further, the metal layer 36 has a net-like shape, and mesh adjustment (adjustment of thickness, mesh density, etc.) is performed so as not to prevent compressive deformation of the inner shell 32 (leg portion 321) due to the inclusion of foreign matter. The metal layer 36 is provided over almost the entire area of the inner shell 32, covers the two conductors 34, and is separated from each conductor 34 so that the two conductors 34 are not short-circuited by the metal layer 36. Are arranged.

  As shown in FIG. 2, the outer shell 33 is formed integrally with the attachment portion 31 and the inner shell 32 by an insulating rubber material. The outer shell 33 further covers the inner shell 32 that covers the space G from the outside. In this way, the outer shell 33 is exposed from the vehicle 1 while being attached to the vehicle 1, and the inner shell 32 is normally shielded from the user by the outer shell 33.

  In the present embodiment, the surface 33a of the outer shell 33 is different from the surface 32a of the inner shell 32 and is not coated with paint or the like. In a state where there is no coloring due to application of paint or the like, the color of the surface 33a in the outer shell 33 is black.

  As described above, in the protector 30 with the touch sensor according to the present embodiment, the color of the surface 32a in the inner shell 32 is set to be different from the color of the surface 33a in the outer shell 33, so And the visual aspect of the surface 32a in the inner shell 32 are set differently. In addition, as a method of setting the visual aspect of the surface to be different, for example, the inner shell 32 and the outer shell 33 may be made of different materials with different colors, or a pattern is provided on the surface 32a of the inner shell 32. Also good. Alternatively, varnish is applied to the surface 32a of the inner shell 32, or the surface 32a of the inner shell 32 is smoothened with respect to the surface 33a of the outer shell 33, thereby making the surface 32a of the inner shell 32 glossy. May be issued.

  The two conductors 34 are formed of a rubber material having conductivity. The two conductors 34 are provided on the inner peripheral edge of the inner shell 32 so that the two conductors 34 face each other in the opening / closing direction (vehicle longitudinal direction) of the slide door 20. For this reason, when the leg portion 321 is compressed and deformed by the inclusion of the foreign matter, the two conductors 34 provided through the space portion G in the inner shell 32 come into contact with each other. When the two conductors 34 come into contact with each other, the two conductors 34 and the core wire 35 embedded in each conductor 34 are short-circuited. Thus, an electric signal different from the case where the two conductors 34 and the core wire 35 embedded in each conductor 34 are not short-circuited is output to the control device 22 shown in FIG. Is detected.

  Next, with reference to FIGS. 3-5, the effect | action of the protector 30 with a touch sensor in this embodiment is demonstrated.

  As shown in FIG. 3, it is assumed that the hole H is formed by breaking the outer shell 33 exposed from the vehicle 1 in a state where the protector 30 with the touch sensor is attached to the vehicle 1. At this time, since the inner shell 32 covers the space G inside the outer shell 33, it is possible to prevent liquid or the like from entering the space G from the hole H.

  As shown in FIGS. 4 and 5, when the metal layer 36 is embedded in the inner shell 32, the inner metal layer 36 composed of a metal material having a higher strength than the material constituting the inner shell 32 The durability of the shell 32 is improved. For this reason, it is further suppressed that liquid or the like enters the space G due to the inner shell 32 being torn.

  Further, the color of the surface 33a in the outer shell 33 is black, whereas the color of the surface 32a in the inner shell 32 is a white fluorescent color. As a result, as shown in FIG. 3, when the outer shell 33 is broken and the hole H is formed in the outer shell 33, the user A can easily see the inner shell 32 exposed from the hole H.

  As described so far, according to the protector 30 with a touch sensor of the present embodiment, the following effects can be obtained.

  -With the structure in which the inner shell 32 covers the space G and the outer shell 33 covers the outer shell 33, for example, even when the outer shell 33 is torn by an external force, liquid or the like enters the space G. Can be suppressed. For this reason, although the inner shell 32 is not compressed and deformed, it is possible to suppress erroneous detection of a foreign substance due to a short circuit between the two conductors 34.

  -If the metal layer 36 is embedded in the inner shell 32, the durability of the inner shell 32 can be improved. For this reason, it is possible to further suppress the erroneous detection of the foreign matter due to the liquid or the like entering the space G covered by the inner shell 32.

  The visual aspect of the surface 32a in the inner shell 32 is set to be different from the visual aspect of the surface 33a in the outer shell 33. Thereby, when the outer shell 33 is torn, the user can easily visually recognize the inner shell 32 from the broken portion (hole H) of the outer shell 33. As a result, the user can repair the broken outer shell 33 at an early stage.

  The color of the surface 32a in the inner shell 32 is set to white fluorescent color, whereas the color of the surface 33a in the outer shell 33 is set to black. Thus, by setting the color of the surface 32a in the inner shell 32 to be different from the color of the surface 33a in the outer shell 33, the visual aspect of the surface 32a in the inner shell 32 can be changed to the surface 33a in the outer shell 33 with a simple configuration. It can be set differently from the visual aspect.

  In addition, you may change the protector 30 with a touch sensor of this embodiment as shown below.

  The color of the surface 33a in the outer shell 33 and the color of the surface 32a in the inner shell 32 are not limited to the present embodiment, and the color of the surface 33a in the outer shell 33 and the color of the surface 32a in the inner shell 32 may be set to different colors. That's fine. In addition, it is more preferable that the color of the surface 33a in the outer shell 33 and the color of the surface 32a in the inner shell 32 are respectively set to colors having a large difference in brightness so that the user can easily see.

  The visual aspect of the surface 33a in the outer shell 33 and the visual aspect of the surface 32a in the inner shell 32 may be the same. Even in this case, by setting the space G to be covered by the inner shell 32 and the inner shell 32 being covered by the outer shell 33, it is possible to suppress erroneous detection of foreign matters that may occur when the outer shell 33 is broken.

  The metal layer 36 as the “protective layer” may be provided so as to cover the surface 32 a in the inner shell 32. In this case, the metal layer 36 covering the surface 32a in the inner shell 32 makes the visual aspect of the surface 32a in the inner shell 32 different from the visual aspect of the surface 33a in the outer shell 33. For this reason, not only can the durability of the inner shell 32 be improved, but also when the outer shell 33 is torn, the user can easily make the inner shell 32 visible.

  -"Protective layer" does not need to be the structure which consists of a net-like member which consists of metal materials. The “protective layer” only needs to be stronger than the inner shell 32, and the material and shape can be changed as appropriate. For example, a film member made of a resin material having higher strength than the material constituting the inner shell 32 may be embedded in the inner shell 32 so as to cover the two conductors 34.

  -A "protective layer" does not need to be provided over the whole area of the inner shell 32, and when the location where external force is often applied is assumed in advance, it may be provided partially at that location.

  The protector 30 with a touch sensor includes a window glass provided on a side door such as the slide door 20 in addition to the slide door 20, a back door provided on the rear side of the vehicle, or a sunroof provided on the roof portion of the vehicle. It may be provided at the periphery of the “opening / closing body” and the periphery of the “opening” at which the “opening / closing body” opens and closes. Note that the protector 30 with the touch sensor is mounted on the vehicle so that the two conductors 34 face each other in the opening / closing direction of the “opening / closing body” regardless of the “opening / closing body” or the “opening”. Preferably it is done.
