  However, in the above-described method, for example, particularly when the cylindrical member is bent or curved, it is caught by friction or the like at the bent or curved portion, and further insertion (the base end of the pressure sensor). There is a problem that it becomes difficult to push the side.

  The present invention has been made to solve the above problems, and an object of the present invention is to provide a method of manufacturing a sensor member that can be easily assembled.

  In order to solve the above-mentioned problems, in the invention described in claim 1, a sensor member for inserting a long elastic pressure sensor into an insertion hole of a cylindrical member that accommodates and holds the pressure sensor. In the manufacturing method, an engagement portion is provided at the distal end of the pressure sensor, and the proximal end of the wire member is engaged with the distal end side of the wire member inserted into the insertion hole. The gist is to pull the pressure sensor into the insertion hole by pulling the side.

  According to the present invention, the pressure member can be pressure-sensitive by simply pulling the proximal end side of the wire member in a state where the distal end side of the wire member inserted into the insertion hole is engaged with the engaging portion provided at the distal end of the pressure-sensitive sensor. The sensor can be retracted and inserted into the insertion hole. At this time, even when the cylindrical member is bent or curved, the pressure-sensitive sensor is inserted smoothly because its tip (engagement portion) is pulled. That is, in the method of pushing the proximal end side of the pressure sensor and inserting the pressure sensor from one end opening of the insertion hole, especially when the cylindrical member is bent or curved, Although it will be caught by friction etc. in a curved part and it will become difficult to insert further (pushing in the base end side of a pressure sensor), the above-mentioned method enables smooth insertion.

  According to a second aspect of the present invention, in the method for manufacturing a sensor member according to the first aspect, the pressure-sensitive sensor is disposed to be opposed to each other inside the hollow insulator and the hollow insulator having elasticity, spaced apart from each other. And a pair of detection electrodes that can be brought into contact with each other by bending with the elastic deformation of the hollow insulator, and a seal member that seals the tip of the hollow insulator, and the elastic deformation of the hollow insulator The pressure is detected by changing at least one of the current value and the voltage value of the current flowing between the pair of detection electrodes due to the contact between the pair of detection electrodes, and the engagement portion includes The gist is that the seal member is integrally formed.

According to the invention, the engaging portion is integrally formed with the seal member that seals the tip of the hollow insulator of the sensor member, so that an increase in the number of components can be avoided.

The pressure is detected by changing at least one of the current value and the voltage value, and the engagement portion is formed integrally with the support member having higher rigidity than the seal member.

  According to the invention, since the engaging portion is integrally formed with the support member that supports the detection electrode at the tip of the hollow insulator having higher rigidity than the seal member (hard to be deformed), the increase in the number of parts is avoided. The rigidity can be increased as compared with the case where the seal member is integrally formed. Also, of course, compared to a pressure-sensitive sensor that does not include a support member, the detection electrode is firmly supported at the tip of the hollow insulator, so that, for example, a pair of detection electrodes are electrically connected via a resistor at this portion. The structure to be maintained can be maintained firmly.

  According to a fourth aspect of the present invention, in the method for manufacturing a sensor member according to any one of the first to third aspects, the pressure-sensitive sensor includes a hollow insulator having elasticity and an inside of the hollow insulator. A pair of sensing electrodes which are arranged to be opposed to each other and can be brought into contact with each other by bending with the elastic deformation of the hollow insulator, and the pair of sensing electrodes on the distal end side of the hollow insulator Is electrically connected, and a current-carrying detection portion is electrically connected to the detection electrode disposed on the proximal end side of the hollow insulator, and the pair of detection electrodes contact with each other due to elastic deformation of the hollow insulator. The pressure is detected by changing at least one of the current value and the voltage value at the energization detection unit, and the engagement unit is configured to detect the pressure of the pressure sensor corresponding to the distal end side of the hollow insulator. Summary that it was provided at the tip To.

  According to the present invention, the engagement portion has a feeling corresponding to the front end side of the hollow insulator to which the pair of detection electrodes are electrically connected without any wiring or the like electrically connected to the energization detection portion. Since it is provided at the tip of the pressure sensor, the wiring or the like does not get in the way and can be easily provided.

According to a fifth aspect of the present invention, in the method for manufacturing a sensor member according to any one of the first to fourth aspects, the engaging portion is formed to be curved.
According to the present invention, since the engaging portion is formed in a curved shape, it is prevented that the engaging portion is caught during insertion, and as a result, smooth insertion is prevented by the engaging portion. Is prevented.

  The door panel 2 is attached to the vehicle body so as to be slidable in the front-rear direction of the vehicle (the direction orthogonal to the paper surface in FIG. 1). When the door actuator 6 (see FIG. 2) of the electric door device 1 (see FIG. 2) is driven, the door panel 2 is slid in the front-rear direction of the vehicle to open and close.

  As shown in FIG. 2, the door actuator 6 includes a motor 7 and a speed reduction mechanism (not shown) that decelerates and outputs the rotation of the motor 7.

When the operation switch 9 is operated by a vehicle occupant or the like to open the opening (entrance / exit), the operation switch 9 outputs an open signal to slide the door panel 2 so as to open the entrance / exit. On the other hand, when the operation switch 9 is operated by a passenger or the like to close the opening (entrance / exit), the operation switch 9 outputs a closing signal to slide the door panel 2 so as to close the entrance / exit. The operation switch 9 is provided in a predetermined part (dashboard or the like) in the passenger compartment, a door lever (not shown) of the door panel 2, a carried item (not shown) carried with the ignition key, or the like.

  In addition, the electric door device 1 includes a sensor member 10 for detecting a foreign object that is a front end portion of the door panel 2 and is present between the abutting surface 2a and the peripheral portion of the entrance / exit. The sensor member 10 is a long pressure-sensitive sensor 11 (see FIGS. 2 to 5) having elasticity, and is formed in a long shape similarly to the pressure-sensitive sensor 11 having elasticity. The cylindrical member 12 (refer FIG.1 and FIG.5) attached to the door panel 2 is stored, and the electricity supply detection part 13 (refer FIG. 2) to which the said pressure sensor 11 was connected is provided.

  As shown in FIG. 1, the sensor member 10 (specifically, the cylindrical member 12 that houses and holds the pressure-sensitive sensor 11) is disposed along the vertical direction on the abutting surface 2 a of the door panel 2, and the latch portion. While being bent or curved so as to avoid 2b or the like, in other words, it has a bent portion 10a, a bent portion 10b, or the like, and is disposed in substantially the entire upper and lower portions of the door panel 2.

  As shown in FIG. 3A, the hollow insulator 22 constituting a part of the pressure-sensitive sensor 11 is formed of an insulating and elastic material (soft resin material, rubber, or the like) and is substantially cylindrical. It has a shape. A spacing hole 22a provided in the radial center portion of the hollow insulator 22 extends along the longitudinal direction of the hollow insulator 22 and penetrates the hollow insulator 22 in the longitudinal direction, and the spacing hole 22a is provided. As a result, the hollow insulator 22 has a hollow portion 22b inside thereof (that is, the hollow insulator 22 has a hollow shape).

  A pair of detection electrodes 23 and 24 held by the hollow insulator 22 are arranged inside the hollow insulator 22. Each detection electrode 23, 24 is formed by twisting conductive thin wires and has a flexible center electrode 25, and a cylindrical conductive coating layer 26 that has conductivity and elasticity and covers the outer periphery of the center electrode 25. It is composed of The two detection electrodes 23 and 24 are disposed opposite to each other in the circumferential direction inside the hollow insulator 22 and are arranged in a spiral shape along the longitudinal direction of the hollow insulator 22. ing. In the present embodiment, the pair of detection electrodes 23, 24 arranged inside the hollow insulator 22 is opposed to the diameter direction of the hollow insulator 22 at any position in the longitudinal direction of the hollow insulator 22. Yes. In addition, about half of the circumferential direction of each of the detection electrodes 23 and 24 is embedded in the hollow insulator 22.

  As shown in FIG. 4, the center electrodes 25 of the detection electrodes 23 and 24 are drawn from the tip 22c, which is one end in the longitudinal direction of the hollow insulator 22, and between the center electrodes 25 drawn from the tip 22c, respectively. A resistor 27 (diag resistor) is connected. That is, the pair of detection electrodes 23, 24 is electrically connected through the resistor 27 at one end portion (tip portion) in the longitudinal direction. Further, the tip 22c of the hollow insulator 22 is sealed by a sealing member 28 in which the center electrode 25 and the resistor 27 of the detection electrodes 23 and 24 drawn out from the tip 22c are embedded (so as to prevent liquid from entering the inside). To be sealed. The seal member 28 is formed of an insulating resin material (for example, an insulating photocurable resin material).

  An engaging portion 28 a is provided at the tip of the pressure sensor 11 corresponding to the longitudinal tip 22 c side of the hollow insulator 22 and at the tip of the seal member 28. The engaging portion 28a can be engaged with a hook portion 31a or the like of a wire member 31 (see FIG. 5), which will be described later, and the entire pressure-sensitive sensor 11 can be pulled by the wire member 31 in the engaged state. In this embodiment, the shape is an arc shape protruding toward the tip side. The engaging portion 28a is integrally formed with the seal member 28.

  Further, on the proximal end side in the longitudinal direction of the hollow insulator 22, as shown in FIG. 2, the detection electrode 23 is electrically connected to the energization detection unit 13 inside the door panel 2, and the detection electrode 24 is Connected to the ground GND (that is, grounded to the vehicle body).

  The energization detection unit 13 supplies a current to the connected detection electrode 23. As shown in FIGS. 2 and 3B, in a normal state where no pressure is applied to the pressure sensor 11, the current supplied from the energization detection unit 13 to the detection electrode 23 has a resistance 27. To the detection electrode 24. On the other hand, as shown in FIG. 3 (c), when a pressing force that crushes the pressure-sensitive sensor 11 in the diametrical direction is applied, the hollow insulator 22 is elastically deformed and accompanying the elastic deformation of the hollow insulator 22. The detection electrodes 23 and 24 are bent, and the detection electrode 23 and the detection electrode 24 come into contact with each other and are short-circuited. Then, the current supplied from the energization detection unit 13 to the detection electrode 23 flows to the detection electrode 24 without passing through the resistor 27. Therefore, for example, when the current is supplied to the detection electrode 23 at a constant voltage, the current value changes. Therefore, the energization detection unit 13 detects the change in the current value at this time, thereby detecting the pressure sensor 11. It is detected that a pressing force is applied to. And the electricity supply detection part 13 will output a pressure-sensitive signal to the door ECU51 mentioned later, if the change of this electric current value is detected. When the pressure applied to the pressure-sensitive sensor 11 is removed, the hollow insulator 22 is restored, and the detection electrodes 23 and 24 are also restored and become non-conductive (short circuit is released).

  As shown in FIG. 2, the electric door device 1 of the present embodiment is controlled by a door ECU 51. The door ECU 51 includes a ROM (Read Only Memory), a RAM (Random Access Memory), and the like, and functions as a microcomputer. The door ECU 51 is disposed, for example, in the vicinity of the door actuator 6 and receives power from a vehicle battery (not shown). The door ECU 51 controls the door actuator 6 based on various signals input from the operation switch 9, the position detection device 8, the energization detection unit 13, and the like.

Next, operation | movement of the electric door apparatus 1 comprised as mentioned above is demonstrated comprehensively.
When an open signal is input from the operation switch 9, the door ECU 51 drives the door actuator 6 to open the door panel 2. The door ECU 51 recognizes the position of the door panel 2 based on the position detection signal input from the position detection device 8. In the present embodiment, the door ECU 51 counts the number of pulses of the position detection signal and recognizes the position of the door panel 2 based on the count value. And if the door panel 2 is arrange | positioned in the full open position which opens the opening part (entrance / exit) of a vehicle completely, door ECU51 will stop the door actuator 6. FIG.

  On the other hand, when a close signal is input from the operation switch 9, the door ECU 51 drives the door actuator 6 to close the door panel 2. And if the door panel 2 is arrange | positioned in the fully-closed position which closes the opening part (entrance / exit) of a vehicle completely, door ECU51 will stop the door actuator 6. FIG. Further, during the closing operation of the door panel 2, a foreign object comes into contact with the sensor member 10 (specifically, the cylindrical member 12 that houses and holds the pressure sensor 11) disposed on the abutting surface 2 a of the door panel 2. When a pressing force is applied, the hollow insulator 22 is elastically deformed so that the pair of detection electrodes 23 and 24 come into contact with each other and are short-circuited. As a result, since the current value of the current supplied to the detection electrode 23 changes, the energization detection unit 13 outputs a pressure sensitive signal to the door ECU 51. When the pressure-sensitive signal is input, the door ECU 51 reverses the door actuator 6 to open the door panel 2 by a predetermined distance and then stops the door actuator 6.

  Next, in the method for manufacturing the sensor member 10 configured as described above, the long pressure-sensitive sensor 11 having elasticity is inserted into the tubular member 12 that accommodates and holds the pressure-sensitive sensor 11. A manufacturing method for inserting into the hole 12a from the one end opening 12b of the insertion hole 12a will be described with reference to FIG.

  In this manufacturing method, the pressure sensitivity is obtained by pulling the proximal end side of the wire member 31 while the distal end side of the wire member 31 inserted into the insertion hole 12a of the cylindrical member 12 is engaged with the engaging portion 28a. The sensor 11 is pulled into the insertion hole 12a and inserted.

  Specifically, first, the wire member 31 is inserted into the insertion hole 12a from the other end opening 12c side of the insertion hole 12a of the cylindrical member 12. The wire member 31 is formed to be sufficiently thinner than the pressure sensor 11, and has a hook portion 31a formed in a substantially U shape at the tip thereof. The hook portion 31a is set to have higher rigidity than the other portions of the wire member 31 so that the entire pressure sensor 11 can be pulled (for example, only the hook portion 31a is made of a material having high rigidity. ) At this time, the wire member 31 is inserted until the hook portion 31a of the wire member 31 is exposed from the one end opening 12b of the insertion hole 12a.

Next, the engaging part 28a provided at the tip of the pressure-sensitive sensor 11 is hooked on the hook part 31a exposed from the one end opening part 12b (see FIG. 5).
Then, by pulling the proximal end side of the wire member 31 (the part protruding from the other end opening 12c), the pressure sensor 11 is pulled into the insertion hole 12a and inserted from the one end opening 12b of the insertion hole 12a. To do. At this time, the wire member 31 is pulled until the tip of the pressure-sensitive sensor 11 is arranged near the other end opening 12c of the insertion hole 12a of the cylindrical member 12. In this way, the sensor member 10 is manufactured. FIG. 5 shows the sensor member 10 in the middle of manufacture in which the tip of the pressure-sensitive sensor 11 is about to pass the position of the bent portion 10a.

Next, characteristic effects of the above embodiment will be described below.
(1) The proximal end of the wire member 31 in a state where the distal end side (hook portion 31a) of the wire member 31 inserted into the insertion hole 12a is engaged with the engagement portion 28a provided at the distal end of the pressure sensor 11. The pressure sensor 11 can be pulled in and inserted into the insertion hole 12a simply by pulling the side. At this time, even when the cylindrical member 12 is bent or curved, the pressure-sensitive sensor 11 is inserted smoothly because its tip (engaging portion 28a) is pulled. That is, in the method in which the pressure-sensitive sensor 11 is inserted from the one end opening 12b of the insertion hole 12a by pushing the proximal end side of the pressure-sensitive sensor 11, particularly when the cylindrical member 12 is bent or curved. The bent portion 10a and the curved portion 10b are caught by friction and the like, and further insertion (pushing the proximal end side of the pressure-sensitive sensor 11) becomes difficult. However, the above method enables smooth insertion. Become. Therefore, the sensor member 10 can be easily assembled.

  (2) Since the engaging portion 28a is integrally formed with the sealing member 28 that seals the tip 22c of the hollow insulator 22 of the sensor member 10 (so that liquid does not enter the inside), the number of parts is reduced. An increase can be avoided.

  (3) The engagement portion 28a is a hollow in which a pair of detection electrodes 23 and 24 are electrically connected (via a resistor 27) without any wiring or the like electrically connected to the energization detection portion 13. Since it is provided at the tip of the pressure-sensitive sensor 11 corresponding to the tip side of the insulator 22, the wiring or the like does not get in the way and can be easily provided. That is, when the engaging portion 28a is provided on the side (base end side) where the wiring or the like for electrically connecting the energization detecting portion 13 is disposed, the wiring or the like becomes an obstacle, but this can be avoided.

  (4) Since the engaging portion 28a is formed in an arc shape protruding toward the distal end side and is curved, the engaging portion 28a is prevented from being caught during insertion, and as a result, the engaging portion The smooth insertion is prevented by 28a.

The above embodiment may be modified as follows.
In the above embodiment, the engaging portion 28a is integrally formed with the seal member 28. However, the engaging portion 28a may be provided at the tip of the pressure-sensitive sensor, and the engaging portion may be provided in another configuration.

  For example, you may change as shown in FIG. The pressure-sensitive sensor 61 of this example (see FIG. 6) has a support member 62 that embeds and supports the detection electrodes 23 and 24, specifically the center electrode 25 and the resistor 27, at the tip 22c of the hollow insulator 22. The engaging portion 62 a is integrally formed with the support member 62. The seal member 63 of this example (see FIG. 6) covers the support member 62 except for the engaging portion 62a, while preventing the tip 22c of the hollow insulator 22 (intrusion of liquid into the interior). To seal). Further, the support member 62 is made of an insulating resin material having higher rigidity (hard to be deformed) than the seal member 63 (28).

  In this case, the engaging portion 62a is higher in rigidity than the seal member 63 (is less likely to be deformed) and supports the detection electrodes 23 and 24, specifically the center electrode 25 and the resistor 27, at the tip 22c of the hollow insulator 22. Since it is integrally formed with the member 62, its rigidity can be increased compared with the case where it is integrally formed with the seal member 28 while avoiding an increase in the number of parts. Of course, the detection electrodes 23 and 24, more specifically, the center electrode 25 and the resistor 27 are firmly supported by the tip 22c of the hollow insulator 22 as compared with the pressure-sensitive sensor 11 that does not include the support member 62. In this portion, the configuration in which the pair of detection electrodes 23 and 24 (the center electrode 25) are electrically connected via the resistor 27 can be firmly maintained.

  In the above embodiment, the engaging portions 28a and 62a are formed in an arc shape that protrudes toward the distal end side, but may have a curved shape that is not an arc shape. For example, as shown in FIG. 7, it may be changed to an engaging portion 62 b having a shape in which one end portion of an arc shape protruding toward the tip side is cut out (not completely closed). In this case, of course, the hook portion 31a provided at the tip of the wire member 31 may be changed to an engaged portion having a closed shape (closed loop shape). Even if it does in this way, the effect similar to the effect of the said embodiment can be acquired. Moreover, you may change into the engaging part which is not a curved shape (shape with a corner | angular shape).

  In the above embodiment, the sensor member 10 is provided on the slidable door panel 2 that can open and close an opening (entrance / exit) provided on the side of the vehicle, but is not limited thereto. Further, it may be provided on a door panel that can open and close an opening (rear gate) provided at the rear of the vehicle. Of course, the sensor member 10 may be provided on the vehicle body side (periphery of the opening) facing the door panels.
