Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle door opening / closing device having a function of automatically opening / closing a vehicle door with an actuator.

[0002]

2. Description of the Related Art Conventionally, as a vehicle door opening / closing device of this type, one disclosed in Japanese Patent Laid-Open No. 2000-96913 is known. The device includes an actuator, a first actuating member movable in a positive direction or a negative direction from a neutral position, and a first actuating member engageable with the first actuating member by moving the first actuating member in a positive direction from a neutral position. An engaging portion, a second engaging portion that is engageable with the first operating member by moving in a negative direction from the neutral position of the first operating member, and a second engaging portion between the first engaging portion and the second engaging portion. A second actuating member which is provided with a movement permitting part for permitting relative movement of the first actuating member and which is actuated by at least the movement of the first actuating member to move the vehicle door between the open position and the closed position with respect to the vehicle body. And a detection member arranged on the actuator side for detecting the drive amount of the actuator, and a control means capable of controlling the actuator by a detection signal of the detection member. This device
When the actuator moves the first actuating member in the forward direction, the first actuating member and the first engaging portion engage with each other. Therefore, the second actuating member is actuated to move the vehicle door, for example, from the closed position to the open position. Then, when the detection amount provided on the actuator side detects the drive amount corresponding to the movement of the vehicle door to the open position, the actuator is stopped.

However, this device is provided with a movement permitting portion for permitting relative movement of the first actuating member between the first engaging portion and the second engaging portion. Therefore, when some external force (an operation force of a person applied to the door and an operation force of the damper device) is applied to the second actuating member, the second actuating member may act more than the actuation of the first actuating member. In this case, the actuator continues to drive until the corresponding drive amount is reached, even though the vehicle door associated with the second actuating member has already reached the predetermined open position. Therefore, there is a problem that the electric power used for driving is consumed more than necessary.

[0004]

SUMMARY OF THE INVENTION An object of the present invention is to reduce power consumption in a vehicle door opening / closing device.

[0005]

The technical means taken in the present invention to solve the above technical problems is an actuator and a first movable first or negative direction from the neutral position by driving the actuator. The operating member is linked to the vehicle door, allows relative movement of the first operating member within a predetermined moving amount, and works in conjunction with the first operating member having a predetermined moving amount or more to move the vehicle door to the vehicle body. A second actuating member for moving to an open position and a closed position;
A configuration that includes an open position detection member that is disposed on the second operation member or the vehicle door and that detects an open position of the vehicle door, and control means that can control the actuator based on a detection signal of the open position detection member. That is.

In this structure, the open position detecting member is arranged on the second actuating member or the vehicle door. That is,
Considering the flow of torque transmitted from the actuator to the vehicle door via the first detection member and the second detection member,
An open position detecting member is provided on the vehicle door side of the detecting member. In other words, the first detection member and the second detection member are relatively movable, but the open position detection member is arranged on the vehicle door side as viewed from the torque flow rather than the relatively movable connection. There is. Then, the open position detection member detects that the vehicle door has reached a predetermined open position. The detection signal enables the control means to stop the driving of the actuator, for example. That is, it is possible to detect the arrival of the vehicle door at the open position regardless of the drive amount of the actuator, and thereby stop the drive of the actuator. Therefore, it is possible to prevent the actuator from continuously driving more than necessary after the vehicle door reaches the open position.
Therefore, power consumption can be suppressed and energy can be saved. When the vehicle door reaches the predetermined open position, the actuator stops immediately, so that the next operation can be appropriately performed. Therefore, the operability is good.

[0007] Preferably, the second actuating member has a first engaging portion engageable with the first actuating member by moving the first actuating member in the positive direction, and a negative direction of the first actuating member. Second engagement portion that is engageable with the first actuation member by moving the first actuation member, and movement allowance that allows relative movement of the first actuation member between the first engagement portion and the second engagement portion. It is preferable to have a configuration including a section.

In this structure, the first engaging portion, the second engaging portion,
The simple configuration of the movement permitting portion completes the linkage between the first operating member and the second operating member.

Preferably, a neutral position detecting member for detecting the neutral position of the first operating member is provided, and the control means is
It is preferable that the first actuating member is moved to the neutral position via the actuator according to the detection result of the open position detection member, and the actuator is stopped according to the detection result of the neutral position detection member.

In this structure, first, when the actuator moves the first operating member in the positive direction from the neutral position, the first operating member engages with the first engaging portion. Therefore, the second operating member operates in the forward direction, and the vehicle door moves from the closed position to the open position, for example. Here, the arrival of the vehicle door at the predetermined open position is detected by the open position detection member as described above. And
Based on the detection result, the control means moves the first operating member to the neutral position. Movement (return) to this neutral position
Is for moving within the movement permitting portion of the second actuating member. The return of the first operating member to the neutral position is detected by the neutral position detecting member. And, by this detection result,
The actuator stops. As a result, the first actuating member stops at the neutral position. The return of the first actuating member to the neutral position brings about the following actions. When the vehicle door is located at the open position, the next operation is to move the vehicle door toward the closed position. Then, in the movement toward the closed position, the first actuating member moves in the negative direction,
This is performed by engaging the first operating member with the second engaging portion and operating the second operating member in the negative direction. Here, the neutral position is a position closer to the second engaging portion than the open position. That is, returning the first actuating member to the neutral position brings about the effect of smoothing the initial operation at the time of the next operation and the operation of moving the vehicle door in the closing direction. In particular,
Since the first actuating member engages the second engaging portion earlier,
The time lag from when the first operating member starts to operate until when the second operating member starts to operate becomes short.

Preferably, the first actuating member is disposed on the vehicle body, the first actuating member is revolvable about an axis by driving the actuator, and the second actuating member is provided on the vehicle body. The second actuating portion, one end of which is pivotally supported by the shaft, the first engaging portion, the second engaging portion, and the movement permitting portion.
The other end of the operating member may be linked to the vehicle door.

In this structure, one end of the second operating member is provided with the first engaging portion, the second engaging portion, and the movement permitting portion.
The linkage between the operating member and the second operating member is completed at one end. Therefore, the whole structure becomes simple.

[0013] Preferably, the movement permitting portion is formed so as to be recessed from an outer peripheral portion of the one end portion in a substantially radial inward direction around the shaft and extend by a predetermined amount in a substantially circumferential direction around the shaft. It is preferable that the open position detection member is disposed outside the outer peripheral portion, and that the detection result is switched by engaging and disengaging with the outer peripheral portion by the rotation of the one end portion.

In this structure, the open position detecting member switches the detection result by the structure of the concave portion which is the movement permitting portion and the outer peripheral portion. Therefore, it is not necessary to separately provide a portion having a function of switching the detection result, and the configuration is simple.

[0015]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings.

As shown in FIG. 1, a vehicle door opening / closing device 1
The (hereinafter referred to as the opening / closing device 1) opens and closes a rear door 3 (vehicle door) provided in a vehicle body 2 (vehicle body) of a one-box type vehicle, for example.

The door 3 has a shape corresponding to the opening 2a of the vehicle body 2, and the hinge mechanism 4 disposed between the vehicle upper side portion of the door 3 and the vehicle body 2 serves as a center.
It is configured to rotate with respect to the vehicle body 2. This rotation causes the door 3 to open and close with respect to the vehicle body 2.

The switchgear 1 is roughly viewed as an arm 21.
A (second operation member), a link 22, and a motor 24 (actuator) are provided. The arm 21 has one end 21a
(One end) is rotatably fixed to the vehicle body 2 side, and is driven by the motor 24 to swing about the one end 21 a with respect to the vehicle body 2. The other end 21b of the arm 21 is linked to the link 22. Link 2
2 is further linked to door 3. And the arm 21
Swings to open / close the door 3 via the link 22. The door 3 can be opened and closed by manual operation regardless of the driving of the motor 24. Details of the opening / closing device 1 will be described later.

As shown in FIG. 1, two damper mechanisms 5 are arranged between the vehicle body 2 and the vehicle door 3. The damper mechanism 5 includes a fixed member 5a and a sliding member 5b.
The sliding member 5b and the fixed member 5a have a core-sheath relationship,
With the opening / closing operation of the door 3, the sliding member 5b moves to the fixed member 5
Slide in a. Further, when the sliding member 5b is inserted into the fixed member 5a, the gas (air or the like) in the fixed member 5a is compressed. Therefore, due to the expansion force of the compressed gas, the sliding member 5b is urged in the direction of jumping out from the fixed member 5a (so that the length of the damper mechanism 5 becomes longer). And the damper mechanism 5 is
The operation (position) of the vehicle body 2 operates as follows. First, when the door 3 is opened with respect to the vehicle body 2 by a predetermined amount or more, the damper mechanism 5 applies a force to the door 3 in the opening direction by an urging force. When the door 3 is open to the vehicle body 2 by a predetermined amount or less, the damper mechanism 5 applies a biasing force to the door 3 in a direction to close the door 3. That is, the damper mechanism 5 has a function of assisting the opening / closing operation of the door 3.

Further, switching of holding / non-holding of the door 3 with respect to the vehicle body 2 in the closed state is performed by engaging / disengaging the latch mechanism 6 and the striker 7. The latch mechanism 6 is arranged on the vehicle lower side of the door 3. The striker 7 has an opening 2a
It is arranged at a position corresponding to the latch mechanism 6 on the lower side of the vehicle. The configurations of the latch mechanism 6 and the striker 7 are well known. Further, a closer 40 (shown in FIG. 4) is arranged near the latch mechanism 6. The closer 40 is roughly provided with a motor 41 and a lever (not shown) operated by the motor. Then, the latch mechanism 6 is operated by the operation of the lever. The operation of the latch mechanism 6 in the engagement direction with the striker 7 is the closing operation of the closer 40, and the operation of the latch mechanism 6 in the direction away from the striker 7 is the open operation. Details of the closer 40 will be described later.

As shown in FIG. 4, the motor 24 and the motor 41
Are electrically connected to a controller 10 (actuator) which is a component of the switchgear 1. The controller 10 is provided in the vehicle body 2, and a remote control that can be carried by a user or a door 3 provided in the vehicle body 2 is provided.
It is configured to receive the signal from the open / close switch for. Therefore, the controller 10 is configured to operate the motor 24 and the motor 41 by receiving a signal from the remote controller or the like.

Next, the switchgear 1 will be described with reference to FIGS. The opening / closing device 1 includes a base 23, a reduction mechanism 25, an output pin 26 (first operating member), a limiter 27 (open position detecting member), a neutral detecting switch 28 (neutral position detecting member), etc. Is equipped with.

The base 23 is a metallic plate-like member and is fixed to the vehicle body 2 with bolts or the like (not shown). The motor 24 is fixed to the base 23, and its driving force is output as the torque of the first pinion gear 25a.
The first pinion gear 25a constitutes the speed reduction mechanism 25, and as the speed reduction mechanism 25, the first gear 2
5b, a second pinion gear 25c, and a second gear 25d. The first gear 25b and the second pinion gear 25c are integrally molded, and are fixed to the base 23 by the shaft 32. The first gear 25b and the second pinion gear 25c are integrally rotatable with respect to the base 23 about the shaft 32. The second gear 25d is fixed to the base 23 by a shaft 33 (shaft). The second gear 25d has a shaft 3
It is rotatable about the base 3 with respect to the base 23. Then, the first pinion gear 25a and the first gear 25
b, the torque of the first pinion gear 25a is transmitted to the second gear 25d by the engagement of the second pinion gear 25c and the second gear 25d.

As shown in FIGS. 2 and 3, the second gear 25d
An output pin 26 that extends in the widthwise direction of the vehicle (leftward in FIG. 3) is disposed in the vehicle. The output pin 26 is configured to revolve around the shaft 33 by the rotation of the second gear 25d.

One end 21a of the arm 21 is fixed to the base 23 via a shaft 33. Further, it is swingable with respect to the base 23 about the shaft 33.
As shown in FIG. 3, there is a certain clearance between the second gear 25d and the arm 21, and the second gear 25d and the arm 21 are relatively rotatable. The one end 21a is
Roughly speaking, the outer peripheral portion 21c (outer peripheral portion) and the concave portion 21d
(Moveable part / recess) The outer peripheral portion 21c has the shaft 3
The distance from 3 is substantially equal to the radius of the second gear 25d. The concave portion 21d is formed to be recessed from the outer peripheral portion 21c by a predetermined amount in a substantially radial direction (described later) and extend in a substantially circumferential direction (described later) by a predetermined amount. Then, two engaging portions 21e extending substantially in the radial direction are provided at both ends of the recess 21d in the substantially circumferential direction.
(First engaging portion) and 21f (second engaging portion) are formed. Here, the radial inward direction is the radial direction and the central direction of the circle when the one end 21a is regarded as a circular shape with the axis 33 as the center. The circumferential direction is the circumferential direction of the circle in the same case. Further, the predetermined amount of extension of the concave portion 21d is an amount that spreads in the direction of approximately 180 degrees about the axis 33 in the present embodiment.

As shown in FIG. 2, the output pin 26 has a recess 2
Located within 1d. Further, as shown in FIG. 3, the tip of the output pin 26 in the vehicle widthwise direction (the leftward direction in FIG. 3) extends in the vehicle widthwise direction from the one end 21a. From the above, when the output pin 26 moves so as to revolve around the shaft 33 (when the second gear 25d rotates around the shaft 33), it operates as follows. First, when the amount of movement is within a predetermined amount, the output pin 26 moves in the recess 21d and the arm 21 does not operate. That is, output pin 2
6 moves relative to the arm 21. However, when the output pin 26 moves by a predetermined amount or more, the output pin 26 engages with the engaging portion 21e or 21f. That is, depending on the movement in the positive direction (counterclockwise direction in FIG. 2) about the shaft 33, the output pin 26 causes the engaging portion 21e to move.
Engage with. Conversely, the output pin 26 engages with the engaging portion 21f depending on the movement in the negative direction (clockwise direction in FIG. 2) about the shaft 33. In addition, the output pin 26 does not move,
It may also occur that the arm 21 swings (the recess 21d moves). That is, when the swing amount of the arm 21 is within a predetermined amount, the engaging portions 21e and 21f do not engage the output pin 26.

As shown in FIG. 2, a limiter 27 is arranged near the one end 21a. The limiter 27 is
It is fixed to a bracket (not shown) fixed to the base 23. Further, as shown in FIG. 4, the limiter 27 is electrically connected to the controller 10, and the limiter 27
The detection signal of is input to the controller 10. Here, the limiter 27 includes a switch piece 27a. The switch piece 27a is positioned so as to be disengageable from the outer peripheral portion 21c of the one end portion 21a. FIG. 2 shows a case where the switch piece 27a faces the outer peripheral portion 21c,
The state where the switch piece 27a and the outer peripheral portion 21c are engaged is shown. Due to this engagement, the limiter 27 is turned on. In this state, the limiter 27 sends an ON signal to the controller 10. Further, FIG. 5A shows a state in which the limiter 27 faces the recess 21d and the switch piece 27a is not engaged with the outer peripheral portion 21c. In this state, the limiter 27 is turned off.

Further, as shown in FIG. 2, a neutral detection switch 28 is arranged near the one end 21a. The neutral detection switch 28 is fixed to a bracket (not shown) fixed to the base 23. Also, as shown in FIG.
The neutral detection switch 28 is also electrically connected to the controller 10, and the detection signal of the neutral detection switch 28 is
It is configured to be transmitted to the controller 10. Here, the neutrality detection switch 28 is arranged at a position where it can be engaged with and disengaged from the output pin 26. And the neutral detection switch 2
When 8 is engaged with the output pin 26, the controller 10
Send an ON signal to.

Next, the closer 40 for closing the door 3 with respect to the vehicle body 2 will be described with reference to FIG. The closer 40 includes a half-latch detection switch 4
2. A full latch detection switch (not shown) and the like are provided. The half-latch detection switch 42 is electrically connected to the controller 10, and the disposition position is near the latch (not shown) of the latch mechanism 6. Then, the rotation state of the latch (the engagement state of the latch mechanism 6 with the striker 7) is detected using the cam surface (not shown) formed on the latch. As a result, the half-latch state of the latch mechanism 6 (half-door state of the door 3) is detected and an ON signal is transmitted to the controller 10. The full-latch detection switch also detects the full-latch state of the latch mechanism 6 (fully closed state of the door 3) by the same action as the half-latch detection switch 42.

The operation of the switchgear 1 will be described with reference to FIGS. FIG. 7 shows a processing flow of the opening operation of the door 3 in the controller 10. In the closed state,
The latch mechanism 6 is engaged with the striker 7, and the door 3 is held with respect to the vehicle body 2. In this state, in step S11, it is determined whether or not an ON signal of an open switch (not shown) provided on the remote controller or the vehicle body 2 is input. If it has been input, the process proceeds to step S12, and if it has not been input, this processing ends. In step S12,
The motor 41 of the closer 40 is operated. The motor 41 actuates the latch mechanism 6 in a direction away from the striker 7 via a lever (not shown). Then step S1
In step 3, it is determined whether the ON signal is input from the half-latch detection switch 42. When it is input, the process proceeds to step S12 and the operation of the motor 41 is continued.
If no input is made, the process proceeds to step S14. In step S14, the motor 24 of the switchgear 1 is operated. This operation moves the output pin 26 in the forward direction (counterclockwise direction shown in FIG. 2). As a result, the output pin 26 engages with the engaging portion 21e of the arm 21, and continues to push the engaging portion 21e in the forward direction. On the other hand, the latch mechanism 6
Is completely disengaged from the striker 7 by the closer 40, the arm 21 rotates in the positive direction about the shaft 33 (the door 3 is opened). After step 14, the process proceeds to step 15 and it is determined whether the ON signal is input from the limiter 27. That is, when the door 3 is fully opened and the ON signal is input from the limiter 27, the process proceeds to step 16. When the door 3 is not fully opened, the ON signal is not input, and the process proceeds to step S14 and the motor 24
Operation continues. The operation of steps S12 to S15 is shown in FIGS. 5a and 5b. That is, FIG.
Shows a closed state of the door 3, and FIG. 5b shows a fully opened state of the door 3. Here, as described above, the limiter 27 is switched from OFF to ON by the engagement of the switch piece 27a and the outer peripheral portion 21c. That is, the concave portion 21d and the outer peripheral portion 21
Since the relationship of the structure of c is used for switching the limiter 27, it is not necessary to separately provide a switching mechanism, and the structure is simple.

In step S16, the motor 24 is driven in the reverse direction to move the output pin 26 in the negative direction (clockwise direction in FIG. 2), and the process proceeds to step S17. In step S17, it is determined whether the ON signal is input from the neutrality detection switch 28. That is, when the ON signal is input by moving (returning) the output pin 26 to the neutral position, the process proceeds to step S18, and when the ON signal is not input, the process proceeds to step S16 and the operation of the motor 24 is continued. To do. In step S18, the operation of the motor 24 is stopped and the process shown in FIG. 7 is ended. As a result, the output pin 26 is returned to the initial position (the position shown in FIGS. 5a and 5c) and stopped. Step S15
The operation from S18 to S18 is shown in FIGS. 5b and 5c. FIG. 5c shows the state in which the output pin 26 has returned to the initial position. Here, as described above, the opening operation of the door 3 is assisted by the damper mechanism 5. Therefore, the door 3 is opened more than the driving amount of the motor 24 (moving amount of the output pin 26).
Even in this case, since the opening / closing device 1 is configured to detect the fully opened position of the door 3 by the limiter 27 provided on the arm 21 side, the output pin 26 is moved to the forward full stroke position (door. It is possible to return to the initial position without moving it to a position corresponding to the fully open position 3). Therefore, the operating time of the motor 24 can be shortened and the power consumption can be suppressed. Although the limiter 27 is arranged on the arm 21 to detect the position of the arm 21 in the present embodiment, as another embodiment, the door 3 is used.
It is also conceivable that the door 3 is installed in the vehicle and the position of the door 3 is directly detected. That is, when the motor 24 is on the torque input side and the door 3 is on the torque output side, the torque output side is almost 1
The effect of the present invention can be obtained by arranging the limiter 27 in a portion that interlocks in a one-to-one relationship, that is, a portion that does not move relatively. Further, it may be arranged on the link 22.

FIG. 8 shows a processing flow from the start to the stop of the opening / closing device 1 in the closing operation of the door 3 of the controller 10. In step S31, it is determined whether or not an ON signal of a remote switch or a close switch (not shown) arranged on the vehicle body 2 is input. If it has been input, the process proceeds to step S32. If it has not been input, this process ends. In step S32, the motor 24 of the switchgear 1 is driven and the process proceeds to step S33. The drive is output pin 2
6 is moved in the negative direction (clockwise direction in FIG. 2). As a result, the output pin 26 is connected to the engaging portion 2 of the arm 21.
It engages with 1f and continues to push the engaging portion 21f in the negative direction. Therefore, the arm 21 rotates in the negative direction about the shaft 33. Along with that, the door 3 is closed. In step S33, it is determined whether the ON signal is input from the half latch switch 42 of the closer 40. That is, when the door 3 reaches the half-door state and the ON signal is input from the half-latch switch 42, step S
Proceed to 34. If the door 3 has not reached the half-door state and the ON signal is not input, the process proceeds to step S32 and the driving of the motor 24 is continued. Incidentally, steps S12 to S1
Operation up to 5 is shown in Figures 6a and 6b. 6a shows the door 3 in a fully open state, and FIG. 6b shows the door 3 in a half-door state. In step S34, the motor 24 is driven in the reverse direction to move the output pin 26 in the forward direction (counterclockwise direction in FIG. 2), and the process proceeds to step S35. Step S3
In 5, it is determined whether the ON signal is input from the neutrality detection switch 28. That is, when the neutral detection switch 28 returns to the neutral position, the process proceeds to step S36 when the ON signal is input, and the process proceeds to step S34 when the ON signal is not input.
Continue to operate. In step S36, the operation of the motor 24 is stopped and the process shown in FIG. 9 is ended. As a result, the output pin 26 is returned to the initial position (the position shown in FIGS. 6a and 6c) and stopped. The operation of steps S33 to S36 is shown in FIGS. 6b and 6c. Figure 6
c shows the state in which the output pin 26 has returned to the initial position. Here, as described above, the closing operation of the door 3 is assisted by the damper mechanism 5. Therefore, the door 3 is closed more than the driving amount of the motor 24 (moving amount of the output pin 26). Even in this case, the opening / closing device 1 sets the position of the door 3 in the half-door state to the half-latch position detection switch 4 of the closer 40.
Since the output pin 26 is configured to be detected in step 2, the output pin 26 does not move to the full stroke position in the negative direction (the position corresponding to the half-door state of the door 3), but the return operation to the initial position is performed. be able to. Therefore, the operating time of the motor 24 can be shortened and the power consumption can be suppressed.
On the other hand, the door 3 in the half-door state is fully closed by the operation of the closer 40 separately.

In the present embodiment, the half-door state of the door 3 is detected by the half-latch position detection switch 42 of the closer 40. However, the limiter 2 is provided near the arm 42.
A switch corresponding to 7 may be separately provided and used.
In the present embodiment, the half latch position detection switch 42
Because it uses, the number of parts is small.
