It is an object of the present invention to provide a new opening / closing detection device and a new opening / closing device useful for avoiding a problem of foreign matter being caught when the sliding door is closed.

[0005]

In order to solve the above problems, a vehicle slide door opening / closing detection device according to a first aspect of the present invention slides along a vehicle body to open / close a body opening. An opening / closing detection device for a slide door, comprising: a detection means at least on one of a body-side peripheral edge of the body opening or a door-side peripheral edge of the slide door facing the peripheral edge. When a foreign object is in contact with the body-side peripheral edge or the door-side peripheral edge while being slid from the opening position where the body opening is opened to the fully closed position, a signal generating means for issuing a predetermined signal Have.

In the vehicle slide door opening / closing detection device of the first invention having the above-mentioned structure, when the slide door is slid along the body of the vehicle to close the body opening, foreign matter is attached to the body side edge or the door side edge. Are in contact,
This foreign substance is present in contact with at least one of the body-side peripheral edge and the door-side peripheral edge. In such a case, since the predetermined signal is generated by the signal generation means of the detection means, the presence of foreign matter in contact with the body side edge or the door side edge is directly detected by the predetermined signal. can do. Therefore, when the slide door is driven to slide, it is possible to prevent the slide door from sliding to the fully closed position of the body opening portion by using a predetermined signal emitted from the detection means. Therefore, according to the open / close detection device for a vehicle slide door of the first aspect of the invention, it is possible to avoid the problem that the slide door is slid to the fully closed position while the foreign matter is sandwiched.

In the opening / closing detecting device for a vehicle slide door according to the first aspect of the present invention, the detecting means is
A hollow body having a hollow gap extending along the body-side peripheral edge or the door-side peripheral edge, first and second conductive portions provided to face each other in the hollow gap of the hollow body with an insulating gap therebetween; 1, a signal generating means for generating the predetermined signal when the second conductive portion comes into contact with the hollow body, and the hollow body is the slide door when foreign matter is present in contact with the body-side peripheral edge or the door-side peripheral edge. Is in a semi-closed position before the fully closed position, and has a hollow gap that is pressed by the foreign matter to contact the first and second conductive portions.

In the vehicle slide door opening / closing detecting device having this structure, when the foreign body is not in contact with the body side peripheral edge or the door side peripheral edge, the slide door is slid to the semi-closed position before the fully closed position. However, the first and second conductive parts facing each other in the hollow gap of the hollow body extending along the body-side peripheral edge or the door-side peripheral edge do not come into contact with each other. On the other hand, when a foreign object is present in contact with the body side edge or the door side edge and the slide door is slid to the semi-closed position and is in this position, the hollow body is pushed by the foreign matter and the first , The second conductive portion is in contact.

For this reason, through the contact between the first and second conductive portions, the signal generating means issues a predetermined signal indicating that the foreign matter is present in contact with the body side edge or the door side edge. In other words, in the vehicle slide door opening / closing detection device having this configuration, when the slide door is slid to the semi-closed position while the foreign substance is present in contact with the body side peripheral edge or the door side peripheral edge, the foreign substance is detected. The presence in contact with the side peripheral edge is directly detected through pressing of the hollow body by a foreign substance, contact of the first and second conductive portions, and generation of a predetermined signal. Therefore, when the sliding door is driven to slide from the semi-closed position to the fully closed position, it is possible to prevent the sliding door from sliding to the fully closed position by using the above-mentioned predetermined signal. As a result, according to the open / close detection device for a vehicle slide door having this configuration, it is possible to avoid the problem that the slide door is driven to slide from the semi-closed position to the fully closed position while the foreign matter is sandwiched.

When the slide door is slid to the semi-closed position while the body side edge or the door side edge is in contact with the foreign matter, the foreign matter pushes the hollow body. Of course, since the hollow space of the body is narrowed, the foreign matter is not caught between the body and the slide door. If this hollow body is made of a soft material such as sponge rubber, it is easily deformed by pressing. Further, the hollow body is not limited to a soft material such as sponge rubber, but may be any elastic body that is pressed and deformed by foreign matter.

An opening / closing device for a vehicle slide door according to a second aspect of the present invention is an opening / closing device for a vehicle slide door, which has a sliding door that slides along a vehicle body to open and close a body opening. When the slide door is in a semi-closed position before the fully closed position where the body opening is fully closed, a door fully closing means for driving the slide door to the fully closed position, and a body side peripheral edge in the body opening or When a foreign object is in contact with the peripheral edge of the slide door facing the peripheral edge and a foreign object is present, a detecting unit that emits a predetermined signal, and when the predetermined signal is emitted, prohibits the drive of the slide door by the fully closing unit of the door. Drive prohibiting means for

In the opening / closing device for a vehicle slide door according to the second aspect of the present invention, when the slide door is at the semi-closed position before the fully closed position, the door fully closed means causes the slide door to reach the fully closed position. Driven. However, the slide door in the semi-closed position is not uniformly driven to the fully closed position, and when foreign matter is present in contact with the body side edge or the door side edge, the slide door drive is performed as follows. Become.

When a foreign object is in contact with the body side edge or the door side edge, a predetermined signal is issued by the detecting means.
That is, the presence of foreign matter in contact with the body side edge or the door side edge is directly detected by this detection means. Then, when this predetermined signal is issued, the drive prohibiting means prohibits the sliding door from being driven by the door fully closing means. Therefore, when the slide door in the semi-closed position is driven to the full-closed position, if foreign matter is present in contact with the body-side peripheral edge or the door-side peripheral edge, the drive of the slide door from the semi-closed position to the full-closed position cannot be performed. Prohibited, sliding doors will remain in the semi-closed position. As a result, according to the vehicle slide door opening / closing apparatus of the second invention, it is possible to avoid the problem that the slide door is driven from the semi-closed position to the fully closed position while the foreign matter is sandwiched.

In the opening / closing device for a vehicle slide door according to the second aspect of the present invention, the drive inhibiting means is
There is provided means for prohibiting drive of the slide door by the door full closing means when the predetermined signal is issued, and for releasing drive prohibition of the slide door when the predetermined signal is released.

In this structure, the opening / closing device for a sliding door for a vehicle is operated from the semi-closed position to the fully closed position when a predetermined signal is emitted from the detecting means, that is, when a foreign substance is present in contact with the body side edge or the door side edge. Driving the sliding door to the position is prohibited and the sliding door remains in the semi-closed position. However, if the foreign matter is removed and the foreign matter comes into contact with the body side edge or the door side edge and does not exist, and the predetermined signal from the detection means is released, the drive prohibition of the slide door is released. After that, the slide door is driven to the fully closed position through the control of the door fully closing means. Therefore, according to the opening / closing device for a sliding door for a vehicle having this structure, the sliding door can be driven to the fully closed position after the foreign matter is removed from the body side edge or the door side edge.

Other Embodiments of the Invention The present invention can also adopt the following other embodiments. The first embodiment is the opening / closing detection device for a vehicle slide door according to the first invention, wherein: The detecting means detects a detection body extending along the body-side peripheral edge or the door-side peripheral edge and an electrical change or a pressure change that occurs in the detection body when a foreign substance comes into contact with the detection body, And a signal generating means for emitting the predetermined signal when a change is detected.

In the first aspect, when a foreign object comes into contact with the detection body extending along the body-side peripheral edge or the door-side peripheral edge, an electrical change or a pressure change occurring in the detection body due to this contact is detected, A predetermined signal is emitted by the signal generating means. For this reason, the presence of foreign matter in contact with the body-side peripheral edge or the door-side peripheral edge is directly detected through the electrical change or pressure change of the detection body due to the foreign matter and the generation of a predetermined signal.

As the detector that causes such an electrical change through contact with a foreign substance, a conductor whose resistance value or the like changes when a foreign substance having weak conductivity contacts is used. Such a conductor may be, for example, a pair of conductive lines that are arranged to face each other along the body-side peripheral edge or the door-side peripheral edge, or a pair of conductive lines that are arranged to face each other along the body-side peripheral edge and the door-side peripheral edge. Composed of lines. In this case, if the pair of conductive lines are connected at their ends with a predetermined resistance interposed, the resistance value changes due to a short circuit due to a foreign substance. On the other hand, if the pair of conductive lines are not connected, electrical continuity is achieved by the foreign matter. Therefore, the contact of the foreign matter can be directly detected by issuing a predetermined signal according to the change of the resistance value or the presence / absence of conduction.

Further, as a detecting body which causes a pressure change through contact with a foreign substance, there is a pressure sensitive sensor or the like for detecting the pressure when the foreign substance is pressed.

The seal portion 28 is made of sponge rubber, and the seal portion 28 is pressed by the inner panel of the slide door 10 to perform a sealing action.

An open / close detection device 30 is fixed to the edge 11 at the side end of the slide door 10 of the body facing the door pillar 13. This open / close detection device 30
When the slide door 10 is slid to its fully closed position, it detects whether or not a foreign object is present in contact with the side surface of the door pillar 13 or the peripheral edge of the slide door 10 facing this. Then, as shown in FIG. 1, the opening / closing detection device 30 is mounted vertically above and below the outside handle 10a of the slide door 10 as the center.

The open / close detection device 30 is provided with a mounting base 32 which is made of solid rubber and is inserted and fixed to the edge portion 11 of the slide door 10, and a hollow portion 34 which is integrally formed with the mounting base 32 by sponge rubber. A hollow gap 34a is formed inside the hollow portion 34, and the hollow gap 34a is formed.
The first conductive portion 36a and the second conductive portion 36b are provided on the inner wall surface.
Are arranged facing each other. The first and second conductive parts 3
6a and 36b are a first wire 38a and a second wire 38b made of a good conductive metal such as copper, and a first wire 38b made of a conductive rubber.
It is configured by covering with the covering portion 40a and the second covering portion 40b,
It is provided over the entire length of the open / close detection device 30. The first and second wires 38a, 38b are connected at one end side of the opening / closing detection device 30 with a predetermined resistance interposed therebetween, and are led out to the outside from the other end side of the opening / closing detection device 30. Slide door full lock relay 22 (Fig. 2
See). Therefore, if the first and second conductive parts 36a, 36b of the opening / closing detection device 30 are short-circuited (short-circuited) at any of the positions, the short-circuit current is input to the slide door full-lock relay 22 as a signal. Become.

The open / close detection device 30 having the above-described structure includes solid rubber for forming the mounting base portion 32, sponge rubber for forming the hollow portion 34, and first and second conductive portions 36a, 36b. And second covering portions 40a, 40b
It is a multicolored extrusion molded product that is extruded together with a conductive rubber for forming the above. When extruding, the wires to be the first and second wires 38a and 38b are introduced into the extrusion die.

The open / close detection device 30 includes a first covering portion 40 when the hollow portion 34 is in an unloaded state as shown in the drawing.
Gap between a and the second covering portion 40b (hollow gap 34a)
As the insulating gap 34b, the first conductive portion 36a and the second conductive portion 36b are separated from each other. The open / close detecting device 30 has a distance of several mm between the tip of the slide door 10 and the door pillar 13 even when the slide door 10 is in the fully closed position shown in the figure.
So that a gap is formed with a width of (about 2-5 mm),
When the sliding door 10 is in the position of a half door diagonally to the lower right of the fully closed position, the shape and size thereof are defined so that there is about 10 mm between the tip portion and the door pillar 13.

Next, the operation of the opening / closing detection device 30 will be described with reference to the operation block diagram showing the operation of the automatic lock mechanism of the slide door 10 described above. First, a case where no foreign matter exists between the slide door 10 and the door pillar 13 (when no foreign matter exists) will be described. In this case, as shown in FIG. 4, even if the slide door 10 is manually slid to the front half door at the fully closed position, the hollow portion 34 of the opening / closing detection device 30 receives no force, and thus the original shape is stopped. Therefore, the open / close detection device 30 does not operate.

When the sliding door 10 becomes a half-door when there is no foreign object, the body side power feeding circuit for feeding power to the slide door full lock relay 22 is ready for power feeding as shown in the operation block diagram of FIG. The state is set (step S100). In the following step S110, it is determined whether or not the half-door detection switch 16 is on, that is, whether the slide door 10 is stopped at the half-door position. In this case, if the sliding door 10 is manually slid with a sufficient force, the sliding door 10 does not stay at the half-door position but slides to the fully closed position. Therefore, a negative determination is made in step S110, and the automatic locking mechanism slides. The door full lock relay 22 is not supplied with power from the power supply circuit. Therefore, the automatic lock mechanism does not operate.

However, when the sliding door 10 is stopped at the half-door position, the half-door detection switch 16 is turned on. Therefore, an affirmative decision is made in this step S100, and in the following step S120, the opening / closing detection device 30 detects the detection operation. To do. That is, the first and second conductive portions 36a and 36b
Is short-circuited and it is judged whether the short-circuit current is input. In this case, since there is no foreign matter, the hollow portion 34 is not deformed, and there is no short-circuit current input from the open / close detection device 30, so a negative determination is made and the step S is performed.
Proceeding to 130, power supply to the slide door full lock relay 22 is started. Then, in the following step S140, the automatic lock mechanism operates to perform full lock. That is, the full lock motor 20 is drive-controlled, and the slide door 10 is forcibly slid from the half door position to the fully closed position. When the slide door 10 is slid to the fully closed position and the full lock detection switch 18 is turned on, the slide door full lock relay 22 is stop-controlled and the full lock ends.

On the other hand, as shown in FIG. 6, when a foreign substance is present between the slide door 10 and the door pillar 13 in contact with either of them (when a foreign substance is present), the automatic lock mechanism operates as follows. To work. First, even if this foreign object exists, when the slide door 10 becomes a half door, power supply to the slide door full lock relay 22 is made ready in step S100, and the slide door 10 becomes a half door in subsequent step S110. It is determined whether it is parked at the position.

When the sliding door 10 is stopped at the half-door position, the half-door detection switch 16 is turned on. Therefore, an affirmative decision is made in this step S110, and in the following step S120, the first and second door opening / closing detecting devices 30 are opened. It is determined whether the second conductive portions 36a and 36b are short-circuited and the short-circuit current is input. In this case, since the foreign matter is present, the hollow portion 34 of the opening / closing detection device 30 is pushed by the foreign matter, and the first and second conductive portions 36a, 36a,
36b is short-circuited, and a short-circuit current is input from the open / close detection device 30. Therefore, when a foreign substance is present, an affirmative decision is made in step S120, and the operation proceeds to step S150.
In step S150, the power supply to the slide door full lock relay 22 is in a standby state, so the automatic lock mechanism does not operate, and the slide door 10 remains in the half door position. And step S
Since the operation from step S100 is repeated after passing through 150, the sliding door 10 stays at the half-door position while the foreign matter is in contact with the sliding door 10 and the door pillar 13.

On the other hand, if the foreign matter is removed, a negative determination is made in step S120, so power supply is started in step S130 and full lock is executed in step S140, and the slide door 10 is moved from the half-door position to the fully closed position. It is forced to slide by the automatic lock mechanism.

As described above, in the vehicle equipped with the slide door 10 of this embodiment, when a foreign substance exists between the slide door 10 and the door pillar 13 in contact with any one of them, the foreign substance causes a hollow. The portion 34 is pushed and the first conductive portion 36a and the second conductive portion 36b are short-circuited,
The presence of foreign matter between the slide door 10 and the door pillar 13 is directly detected by the short-circuit current at this time. For this reason, in the present embodiment, when the slide door 10 is driven to slide, it is possible to prevent the slide door 10 from sliding from the half-door position to the fully closed position when a foreign substance is present. Therefore, according to the vehicle equipped with the slide door 10, it is possible to surely avoid the problem that the slide door 10 is slid to the fully closed position with the foreign matter sandwiched therebetween.

Incidentally, the slide door 10 and the door pillar 13
It is also possible to continuously input a short-circuit current due to the first conductive portion 36a and the second conductive portion 36b as long as a foreign substance is in contact with and existing between and. The drive of the slide door to the fully closed position of the half-door slide door 10 is prohibited, and the slide door 10 remains in the half-door position. However, when the foreign matter is removed, this short-circuit current disappears, and thereafter, the slide door 10 can be promptly driven from the half door position to the fully closed position.

Further, in the above embodiment, the open / close detection device 3
When the short current is input from 0, step S12
Upon receiving an affirmative judgment of 0, the power supply to the slide door full lock relay 22 is put in a standby state. Therefore, there are the following effects. When the foreign matter between the door pillar 13 and the sliding door 10 is small, the open / close detection device 30 is not short-circuited by the foreign matter when the sliding door 10 is in the half door position, and the sliding door 10 is in the half door position. The open / close detection device 30 may short-circuit when it is slightly slid from. However, even in such a case, the slide door 10 can be stopped in place by the input of the short-circuit current from the opening / closing detection device 30 through the standby for the subsequent power supply. Therefore, even if a small foreign object that does not press the open / close detection device 30 is sandwiched when the slide door 10 is in the half door position, the slide drive is immediately stopped if a short-circuit current is input in the subsequent slide drive. It is also possible to avoid the problem that the slide door 10 is driven to slide to the fully closed position thereafter.

Next, a modified example will be described. In the above-described embodiment, the hollow portion 34 is inserted and fixed to the edge portion 11 of the slide door 10 via the attachment base portion 32, but it may be modified as follows. In the first modification, the open / close detection device 30A shown in FIG. 7 is fixed to the slide door 10. That is, this open / close detection device 30A has the hollow portion 34, the first conductive portion 36a, the second conductive portion 36b, and the like on the tip side, and the solid rubber mounting on the base side, as in the above embodiment. It has a base 31. In this mounting base 31,

The resin clip 33 is configured so that the opening / closing detection device 30A can be fixed by returning the tip thereof to the original shape by passing through the attachment base 31 and the attachment hole formed in the slide door 10. There is. It is needless to say that the open / close detection device 30A of the first modified example can also avoid the problem of foreign matter being caught when the slide door 10 is closed, as described above. In addition, the opening / closing detection device 30A of the first modified example does not come out from the outside panel of the slide door 10 and does not give a feeling of strangeness.

As shown in FIG. 8, in the opening / closing detection device 30B of the second modification, a solid rubber mounting base 37 is fitted into a dedicated retainer 35 provided on the front side panel of the slide door 10. Thus, it is directly fixed to the front side panel of the slide door 10. And this second

Then, the first and second wires 56a, 5
6b is connected to one end side of the opening / closing detection device 50 with a predetermined resistance interposed, and is led to the outside from the other end side, and similarly to the above-mentioned opening / closing detection device 30, the slide door full lock relay 22 ( (See FIG. 2). Therefore, the first and second conductive parts 54a of the open / close detection device 50,
If 54b is short-circuited at any of the locations, the short-circuit current is input to the slide door full lock relay 22 as a signal. Therefore, also with the opening / closing detection device 50 of the third modified example, it is possible to avoid problems due to the entrapment of foreign matter.
Further, since the open / close detection device 50 of the third modification does not require the hollow portion 34, the structure can be simplified.
