Problems solved by technology
[0007] However, in the case of the above-mentioned contact sensor unit, for example, there is a possibility that the outer wall of the hollow member is damaged due to contact with luggage or the like, so that water may intrude into the inside thereof.
In addition, in this case, there is a possibility that the conduction between the first electrode and the second electrode based on the elastic deformation of the hollow member cannot be accurately detected (for example, an insulating film is formed on the conductive member constituting each electrode). There is still room for improvement on this

Embodiment Construction
[0042]Hereinafter, a first embodiment in which a touch sensor device for a vehicle is realized will be described with reference to the drawings.
[0043] Such as figure 1 As shown, the vehicle 1 of the present embodiment includes a slide door 5 that opens or closes the door opening 3 provided on the side surface 2 a of the vehicle body 2 . In the vehicle 1 of the present embodiment, the sliding door 5 has a configuration as a so-called rear opening type rear door. That is, the sliding door 5 passes toward the rear side of the vehicle ( figure 1 The right side in ) moves to perform the opening action, by moving toward the front side of the vehicle ( figure 1 The left side in ) moves to perform the closing action. Further, the sliding door 5 is provided with a touch sensor unit 10 extending in the vertical direction along the front edge portion 5f thereof. Further, the vehicle 1 according to the present embodiment is provided with a touch sensor device 11 that detects foreig...

A contact sensor device provided by the invention can quickly detect that water intrudes into the hollow part. The touch sensor device 11 includes: a touch sensor unit 10 having a tubular hollow member 20 constituted by an elastically deformable insulator and first and second electrodes 21 and 22 extending in a longitudinal direction of the hollow member and apart from each other in a state of being sealed on an inner side of the hollow member, in which the touch sensor unit is configured such that the first electrode and the second electrode are in contact with each other and electrically connected based on elastic deformation of the hollow member, and a water intrusion detection section 40 is provided at a position located at a lower end portion 10a of the touch sensor unit extending ina vertical direction and, in a case where water has intruded into the hollow member, the first electrode and the second electrode are electrically connected via the intruding water in the water intrusion detection section.
Description
technical field [0001] The invention relates to a touch sensor device. Background technique [0002] Generally, a door of a vehicle is provided with a touch sensor for detecting entrapment of a foreign object. For example, the touch sensor device described in Patent Document 1 includes a touch sensor unit that has a cylindrical hollow member made of an elastically deformable insulator, and is packaged inside the hollow member at intervals from each other. The state of the first electrode and the second electrode extending along the extending direction of the hollow member. Furthermore, the touch sensor unit is configured such that, by elastically deforming the hollow member, the first electrode and the second electrode arranged in the hollow member are brought into contact with each other to conduct conduction. In addition, by detecting the application of an external force to the touch sensor unit in this way, it is possible to detect the entrapment of a foreign object in ...
