Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pressure sensing device for detecting whether an external force such as a pressing force has acted within a predetermined range.

[0002]

2. Description of the Related Art As a pressure sensing device having a cord switch which is long in its entirety and which can detect that a pressing force is applied even if any portion along the longitudinal direction is pressed,
There is a type having a cord switch of a type in which long electrodes are fixed to an inner peripheral portion of an outer skin portion in a state of being separated from each other inside a long tubular outer skin portion having insulation and elasticity.
In this type of code switch, when the outer cover is elastically deformed by the pressing force, the electrodes come into contact with each other and short-circuit, so that the electric resistance value of the electric circuit including the electrodes is sharper compared to the state before the contact. Change. By detecting a sudden change in the electric resistance value or the current value, it is configured to recognize that a pressing force has acted on the outer skin portion.

[0003]

In such a code switch, the electrodes must be electrically connected to a computer or the like. In this case, it is common to connect the other end of the lead wire, one end of which is directly or indirectly electrically connected to a computer or the like, to the longitudinal end of the electrode.

Here, Japanese Patent Application Laid-Open No. 61-248310 discloses an example of a method for electrically connecting an electrode and a lead wire.

[0005] The method of Japanese Patent Application Laid-Open No. 61-248310 will be briefly described. A part of the outer periphery of the outer skin is locally cut off in the vicinity of the end of the outer skin to expose an electrode inside the outer skin. After the end of the lead wire is fixed to the electrode from the cut portion, the cut portion is covered with an insulating member having elasticity.

However, according to this method, the lead wire is exposed outside the cut portion covered with the insulating member. Therefore, when foreign matter or the like comes into contact with the lead wire, the lead wire is pulled by the pressure from the foreign matter. As a result, the connection between the lead wire and the electrode may be broken.

In view of the above, it is an object of the present invention to provide a pressure sensing device capable of preventing a disconnection at a connection portion between a terminal portion of an electrode and a lead wire for making an electrical connection with the outside. .

[0008]

According to a first aspect of the present invention, there is provided a pressure sensing device, wherein a hollow outer skin portion elastically deformable by an external pressure is provided inside the outer skin portion while being separated from each other, and a terminal portion is provided at the outer skin portion. A plurality of electrodes pulled out of the plurality of electrodes, connected to a terminal portion of the plurality of electrodes, and a connecting member connected to a determination unit that determines whether the plurality of electrodes have contacted, and supporting the outer skin portion And a support member having a hole through which the connection member and the terminal portion are inserted in a state where the terminal portion of the outer cover is curved.

According to the pressure sensing device having the above configuration, the connecting member is inserted into the hole of the supporting member in a state where the terminal portion of the outer skin is curved, so that the connecting portion between the connecting member and the terminal portion of the electrode is formed. , Is located on the side opposite to the side where the outer skin portion is supported via the holes, that is, on the side where external pressure is not applied. Therefore, the foreign matter does not touch the connection member, and disconnection or the like due to this can be prevented.

Further, since the outer cover is elastically deformable, it can be easily curved, and the terminal portion can be easily drawn into the hole of the support member. Here, the term “bending” means that the outer skin portion is bent to such an extent that a plurality of electrodes provided separately from each other inside the outer skin portion do not contact each other.

The pressure sensing device according to a second aspect is characterized in that the support portion is provided with a cover for covering a curved portion of the outer skin portion.

Therefore, the curved portion of the outer skin can be protected by the cover, and contact of the foreign matter with the curved portion can be prevented.

As shown in FIG. 7, a bracket 30 extending inward in the vehicle width direction is integrally fixed to a lower end portion of the door panel 14. As shown in FIG. 8, a roller 32 is pivotally supported at the tip end of the bracket 30. Further, the roller 32 is provided on a guide rail 34 provided on the back side of a floor panel (not shown) of the vehicle 12. It is in contact with the outer surface in the vehicle width direction. This roller 32
Is generally the vehicle 1 while rolling due to friction with the guide rail 34.
2 can be moved in the front-back direction. However, as shown in FIG. 8, the outer end in the vehicle width direction of the guide rail 34 is inclined toward the inside in the vehicle width direction at the front end side, and the roller 32 rolls along this inclined portion. As a result, the roller 32 moves inward in the vehicle width direction while moving forward of the vehicle 12, and is displaced inward in the vehicle width direction of the side wall 18 to fit into the opening 20. Further, the roller 32 moves to the outside in the vehicle width direction while moving to the rear side of the vehicle 12 and
The door panel 14 that has been fitted into the door 12 moves outward in the vehicle width direction of the side wall 18 and becomes slidable in the front-rear direction of the vehicle 12.

The slide motor 52 is operated or stopped by supplying or stopping the supply of electric power. Thus, the door panel 14 can be slid (open / closed).

That is, the mechanism for opening and closing the door panel 14 of the vehicle 12 employs a so-called automatic sliding door device which opens and closes the door panel 14 by sliding it back and forth by the driving force of a slide motor 52.

As shown in FIG. 10, the slide actuator 50 has a position detecting device 60. The position detection device 60 is provided corresponding to the rotation axis of the slide motor 52, and can detect the rotation amount of the rotation axis from the time when the slide motor 52 starts driving.

The rotation of the rotary shaft of the slide motor 52 is transmitted to an output shaft via a reduction gear, and the rotation of the output shaft rotates the drive roller 38 (see FIG. 8) to rotate the endless belt 40. Then, the door panel 14 is configured to slide. Therefore, the sliding amount of the door panel 14 is proportional to the rotation axis of the output shaft, and the rotation amount of the output shaft is proportional to the rotation amounts of the reduction gear and the rotation shaft. Therefore, the sliding amount of the door panel 14 can be calculated by measuring the rotation amount of the rotating shaft from the start of the slide motor 52.

On the other hand, as shown in FIG. 9, a bracket 62 extending inward in the vehicle width direction is provided at an intermediate portion and an upper end portion of the door panel 14 in the vertical direction. Rollers (not shown) are provided at the distal ends of these brackets 62, each of which enters a guide groove 50 of a guide rail 64 provided at an appropriate position of the vehicle 12 in a state where it is prevented from falling off, and this guide rail is provided.

That is, the door panel 14 is supported on the side wall 18 of the vehicle body 16 via the guide rail 64 and the bracket 62, and moves while being guided by the guide rails 34 and 64 by the driving force of the slide actuator 50 described above.

The guide rail 64 is also a guide rail 3.
Similarly to 4, the front end side is inclined inward in the vehicle width direction. In this inclined portion, the roller of each bracket 62 moves inward in the vehicle width direction while moving forward of the vehicle 12 along the guide groove 66 of the guide rail 64, or moves outward in the vehicle width direction while moving backward of the vehicle 12. Moving. During this movement, the door panel 14 moves in and out of the vehicle width direction.

As shown in FIG. 7, a closer actuator 70 is disposed inside the door panel 14. As shown in FIG. 10, the closer actuator 70 includes a closer driver 72 constituting control means and a closer motor 74 as drive means. The closer driver 72 is electrically connected to the computer 56, and the door panel 14 is slid toward the direction in which the opening 20 is closed by the driving force of the slide motor 52 (ie, toward the front of the vehicle 12). When the above-described position detection device 60 detects the sliding of the door panel 14 until the door panel 14 is about to close the front of the opening 20, the computer 56 operates the closer driver 72 and supplies the closer motor 74 to the closer motor 74. It is driven by supplying electric power. Thereby, the closer motor 74 activates a lock mechanism (not shown) of the door panel 14 such as a latch provided on the door panel 14 when the door panel 14 is fitted into the opening 20, and
The door panel 14 is guided to a predetermined position in the opening 20 where the door panel 14 can be locked by the lock mechanism.

Is held between the other vertical wall 102 so that both ends face each other along the longitudinal direction, is gripped in a state of being wrapped by the other swaged piece 108 which is swaged, and is fixed by welding. Have been. Thus, the electrode 90 and the electrode 92 are electrically connected via the resistor 98.

On the other hand, as shown in FIG. 1, a plurality of vertical walls 11 are provided on the back side (the side shown in FIG. 1) of the terminal plate 96.
2 are erected. The lower ends of the electrodes 88 and 94 are arranged between the vertical walls 112, and each is held by being swaged by the swaged piece 108 and fixed by welding. Each of the caulking pieces 108 to which the terminal portions of the electrodes 88 and 94 are fixed is attached to the end of the pair of lead wires 122 and 124 of the cord 120 as a connecting member. It is fixed similarly to. These lead wires 122 and 124 are elongated in the same direction as the lead-out direction of the electrodes 88 and 94 (that is, pulled out from the caulking piece 108 outward in the radial direction of the outer cover 84). As shown in FIG. 2, it is disposed inside the door panel 14 through a through hole 126 formed at the front end of the door panel 14, that is, between the outer panel 26 and the inner panel 28 constituting the door panel 14. FIG.
As shown in FIG. 7, the leads 122 and 124, that is, the cord 120 are electrically connected to a power supply, and the above-described electrodes 88 and 94 are supplied with electricity from the power supply via the cord 120. In FIG. 11, the cord 120 is shown as being directly connected to a power source.
Another connection means may be interposed between the power supply 0 and the power supply. In particular, this embodiment has a configuration in which the code switch 10 is applied to an automatic sliding door device, and as described above, the door panel 14 is configured to slide. In the case where the power supply is provided on the vehicle body 12 side in such a configuration (that is, in the case of the configuration 9 in which the door panel 14 moves relatively to the power supply, for example, the power supply is connected to the cord 120 via a sliding contact). Sometimes it is better to connect

On the other hand, although not shown in detail, the outer skin 84
A terminal plate 96 is also provided at the upper end of. However, no resistor 98 is provided on the upper terminal plate 96. On the front side of the upper terminal plate 96, the upper end of the electrode 88 and the upper end of the electrode 92 are swaged similarly to the lower ends of the electrodes 88 to 94.

8. It flows to the electrode 94 via the electrode 90. The electrode 88 is elastically deformed to the extent that the outer skin 84 is crushed.
If any one of the contacts 94 makes a short circuit, the current flows without passing through the resistor 98, so that the resistance value of the entire circuit decreases and the current value increases. Here, as shown in FIG.
The current flowing from the power supply returns to the power supply via the current detecting element 132 as a judging means for transmitting a signal when a current equal to or more than a predetermined value is detected. Then, when the current increases, a signal is transmitted from the current detecting element 132, and the signal is received by the computer 56 (see FIG. 10) which is electrically connected to the current detecting element 132.

Further, as shown in FIG.
A cord 120 connected to the lower end of the cord 94 extends from the lower end of a mold 150 as a sealing member described later, and is formed below the lower end of the code switch 10 at the front end of the door panel 14. 126 through the interior of the door panel 14 (more specifically, the door panel 14
Between the outer panel 26 and the inner panel 28)

The protector 136 includes a holding portion 138 formed in a cylindrical shape along the longitudinal direction. The inner diameter of the holding portion 138 is substantially the same as the outer diameter of the outer skin portion 84, and holds the sensor body 82 inserted therein. Therefore, in practice, the holding portion 138 is elastically deformed by receiving the external pressure, so that the outer skin portion 84 is indirectly elastically deformed by receiving the external pressure. A mounting portion 140 is formed so as to protrude radially outward from a part of the outer periphery of the holding portion 138.

As shown in FIG. 2 and FIG.
40 is formed substantially uniformly along the longitudinal direction of the holding portion 138. The mounting portion 140 is provided with a mounting groove 142 that opens toward the opposite side to the holding portion 138.
A holding piece 144 is formed so as to protrude toward the other inner wall from one of the inner walls facing each other of the mounting groove 142, and is inserted into the mounting groove 142 inside the door panel 14 (more specifically, the inner panel 28). When the plate-shaped bracket 146 having an L-shaped cross section fixed to the inner surface of the
The holding piece 144 is elastically deformed, and the restoring force (elastic force) presses the bracket 146 against the other inner wall side in the mounting groove 142 to hold the bracket 146. Thus, the code switch 10 is fixed to the door panel 14.

Further, as shown in FIGS. 1, 5 and 6, a mold 150 is provided at the lower end of the outer cover 84. The mold 150 is formed of an insulating and heat-flexible rubber material or a synthetic resin material. Inside the mold 150, terminal portions of the electrodes 88 to 94 drawn out from the lower end of the outer skin portion 84, Electrodes 90, 92
, And the electrodes 88 and 94 and the cord 1
The connection portions between the lead wires 122 and 124 are sealed, and the lead wires 122 and 124 and the mold 150 are inserted into the through holes 126 with a part of the outer cover 84 being curved. That is, as shown in FIGS. 2 and 12,
With the cord switch 10 attached to a bracket 146 (a support member of the present invention) that supports the door panel 14,
The cord switch 10 pulled out from the end of the protector 136 has its outer skin 84 gradually bent, and
5 is formed, and the tip portion (mold 150) is formed with the through hole 1
26 and the lead wires 122 and 124 are
4. An annular grommet 127 is attached to the through hole 126, and the outer periphery of the outer cover 84 is in close contact with the inner periphery of the grommet 127. A cover 160 is attached to the front lower end of the door panel 14 so as to cover the curved portion 85. The cover 160 is made of metal or resin and covers an area from the end of the protector 135 to the lower end of the door panel 14. That is,
The cover 160 covers all portions of the curved portion 85 formed by bending the outer skin portion 84.

Although not shown in detail, the outer skin 84
A mold 150 is also provided at the upper end of the. The upper mold 150 has a lower part in close contact with the outer periphery of the upper end part of the protector 136, and the outer skin part 84 and the protector 13.
6 is sealed at the upper end. Also, the upper mold 15
In the inside of 0, the terminal portions of the electrodes 88 to 94 drawn out from the upper end of the outer skin portion 84 and the conducting wires connecting these terminal portions are sealed and held at a predetermined position.

Next, the operation and effect of the present code switch will be described. The code switch 10 attached to the door panel 14 slides with the door panel 14 when the door panel 14 slides by the driving force of the slide motor 52. The door panel 14 is the vehicle 12
When the slide motor 52 starts driving from the state where the opening 20 is opened by sliding to the rear side of the vehicle and the door panel 14 is slid to the front side of the vehicle 12, it , Door panel 14
The code switch 10 that slides with the foreign matter contacts the foreign matter, and the code switch 10 presses the foreign matter toward the front side of the vehicle 12. When a pressing reaction force from the foreign matter at this time acts on the code switch 10, the protector 136 and the outer skin portion 84 are elastically deformed by the pressing reaction force, and any of the electrodes 88 to 94 inside the outer skin portion 84 comes into contact with each other. . In this state, as described above, the electric resistance of the electric circuit including the electrodes 88 to 94 (see FIG. 11) changes, and the current value flowing through the circuit sharply increases. When the current detection element 132 detects this rise in the current value, the current detection element 132 transmits a signal, and the transmitted signal is sent to the computer 56. The computer 56 that has received the signal transmits the slide driver 5
4 is operated to reversely drive the slide motor 52, and the door panel 14 is slid again toward the rear side of the vehicle 12. This prevents foreign matter from being caught by the door panel 14.

The end of the code switch 10 is sealed by a mold 150. Therefore, foreign matter such as water droplets does not enter from the end of the outer cover 84. In addition, the mold 150 has the terminal plate 96 sealed therein, and the periphery of each member such as the resistor 98, the connection portions between the electrodes 90 and 92 and the resistor 98, and the electrodes 88 and 94 and the lead wires 122 and 124. A rubber material or a synthetic resin material forming the mold 150 is in close contact with the periphery of the connection portion with the mold 150, and these are held by the mold 150 from the outside. Therefore, disconnection or the like of the connection portion due to an impact from the outside of the mold 150 or the like is prevented.

Further, as shown in FIGS. 2 and 12, in the cord switch 10, a through-hole formed in the inner panel 28 in a state where the outer cover 84 drawn out of the protector 136 is curved to form a curved portion 85. The terminal portion (the connection portion with the lead wires 122 and 124) is inserted into 126. Therefore, foreign matter or the like does not come into contact with the lead wire on the front side of the door panel 14, and disconnection or the like due to this can be prevented. Further, since the lead wires 122 and 124 drawn out of the mold 150 can be passed through the through hole 126 as they are, when the code switch 10 is assembled to the door panel 14,
There is no need to bend the lead wires 122 and 124 so that the lead wires 122 and 124 penetrate through the lead wire 6, and the handling of the lead wires 122 and 124 becomes extremely easy. Thereby, the workability in the assembling process of the code switch 10 can be improved, and the assembling cost can be reduced.

Further, since the grommet 127 attached to the through hole 126 is in close contact with the outer periphery of the outer skin portion 84, it is possible to prevent water from entering the door panel 14 through the through hole 126. Further, a cover 160 is attached to the front lower end portion of the door panel 14 so as to cover the curved portion 85. Since the cover 160 covers all portions of the curved portion 85, the curved portion 85 can be protected by the cover 160. Thus, contact of the foreign matter with the curved portion 85 can be prevented. Also, the through holes 12
6 can surely be prevented from entering water droplets and the like. The curved portion 85 is a portion drawn out of the protector 136. By covering this portion with the cover 160, the appearance of the vehicle 12 (the door panel 14) can be improved.

As a modified example of the above structure, for example, as shown in FIG.
May have a concave cross section, and the mold 150 may be fitted into the concave portion. As a result, the end (mold 150) of the code switch 10 is stably held in the inner panel 28.
To prevent vibration when the vehicle 12 is running or when the door panel 14 is opened and closed, and disconnection of the lead wires 122 and 124 can be prevented.

As another modified example, as shown in FIG. 14, instead of the cover 160, for example, an end portion made of a rubber material or a synthetic resin material having an insertion hole 172 formed in advance in a curved shape is provided. Protector 170 to inner panel 2
8 and the outer skin portion 84 may be inserted into the insertion hole 172. According to this, the curved portion 85 can be easily formed by inserting the outer skin portion 84 into the insertion hole 172, and the curved portion 85 can be protected similarly to the cover 160, so that foreign matter contacts the curved portion 85. Can be prevented.
