Description

  The present invention relates to an apparatus for regulating an opening operation of an automobile door.

A general automobile door is attached to a vehicle body by a hinge, and the opening and closing operation is performed by turning around the hinge. Therefore, when the door is opened, the door projects to the outside of the vehicle body according to the opening degree. For this reason, if there is an obstacle such as an adjacent vehicle in the protruding region of the door when the door is opened, the door interferes with the obstacle.
Therefore, conventionally, a door for an automobile is equipped with a so-called door checker as a mechanism for stopping the door in a fully open state (full open position) where the door is opened to the maximum and a half open state (intermediate holding position) where the door is opened halfway. .

  This door checker has an arm having a base end swingably mounted in the vicinity of a door hinge portion on the vehicle body side and having a stopper at a distal end, and a slider provided on the door side and sliding relative to the arm. It consists of a sliding member. When the door is fully opened, the slider abuts against the stopper to completely restrict the further opening of the door. Further, the slider is pressed against the peripheral surface of the arm by an elastic force, and a bent portion such as a reduced diameter portion is provided on the peripheral surface of the intermediate portion of the arm, and the slider receives a large sliding resistance at the bent portion. As a result, the door is held at the intermediate holding position.

  The intermediate holding position will be described with reference to FIG. FIG. 7 is a graph showing a correspondence relationship between an operation force (operation torque) necessary for opening and closing a conventional automobile door and the opening of the door. As shown in FIG. 7, an intermediate holding position (A in the figure) is set between the fully closed position (0 in the figure) and the fully open position (B in the figure) of the door, and before and after the intermediate holding position. As described above, since the sliding resistance with respect to the arm of the slider is increased, the operation torque required for the door opening / closing operation when performing the door opening / closing operation increases.

By providing such an intermediate holding position, the door can be prevented from opening and closing against the intention of the door operator without holding the door by hand when the door is open to the intermediate holding position. Can be maintained in a half-open state.
The number of intermediate holding positions, the position (door opening), or the setting of operation torque for opening and closing the door from the intermediate holding position is determined by the shape of the door checker arm and the pressing force on the slider arm.

  However, the intermediate holding position that can be set by such a door checker is about 1 or 2 from the structural condition (the arm length cannot be increased and a large number of bent portions for intermediate holding cannot be formed). If the distance between the host vehicle and other obstacles such as adjacent vehicles is small, such as a narrow parking lot, the door and the obstacle contact each other before opening the door to the intermediate holding position. May end up.

In this way, when the distance to the obstacle is short, the door cannot be opened to the intermediate holding position, so that the door operator or the like holds the door by hand to avoid contact with the obstacle. It is necessary to continue, and this is a big burden.
Also, in the case of a door checker, if the operating torque at the intermediate holding position is set too large, it will be a heavy burden on the operator when the door is opened further from the intermediate holding position or closed from the intermediate holding position. The torque must be set so that it is below a certain level. For this reason, when the door's own weight is applied to the door due to wind pressure due to wind, road surface inclination, etc., a force exceeding the operation torque at the intermediate holding position acts on the door, and the door may be released from the intermediate holding position. is there.

Regarding such a problem, Patent Document 1 discloses that an obstacle that may cause an obstacle to the opening of the door is detected by a sensor, and when the obstacle is detected, a motor is driven to contact a stopper rod. A technique for locking the door opening has been proposed.

One end of the arm portion 3B is pivotally connected around the hinge portion 3A, and a stopper portion 3D having a diameter sufficiently larger than that of the arm portion 3B is formed integrally with the arm portion 3B on the other end side.

  The sliding member 3C is provided with a slider (not shown) that moves relative to the arm portion 3B while being pressed against the peripheral surface of the arm portion 3B by an elastic force. It is installed. Then, the arm portion 3B is inserted through an opening provided in the central portion of the sliding portion 3C, and the arm portion 3B moves relative to the sliding portion 3C according to the opening / closing operation of the door 2 as shown by a two-dot chain line in FIG. By relatively moving forward and backward, the slider of the sliding member 3C and the arm portion 3B slide.

Further, the sliding range between the slider of the sliding member 3C and the arm portion 3B is regulated by the sliding portion 3C coming into contact with the stopper portion 3D. That is, the position where the slider of the sliding member 3 </ b> C contacts the stopper 3 </ b> D is the maximum door opening of the door 2.
A recess 3E for defining the intermediate holding position of the door 2 is provided in the vicinity of the center of the arm portion 3B. The slider of the sliding member 3C presses against the bent surface in the recess 3E, thereby causing a large sliding. Due to the sliding resistance, an operating force (operation torque) necessary for opening and closing the door when the door is moved in the opening and closing direction is set appropriately.

  One end (tip portion) of the wire 4 is connected to the stopper portion 3D of the door checker 3. The other end side (base end portion) of the wire 4 is wound around the pulley 5 and then connected to the pulley 5. The pulley 5 rotates according to the relative displacement of the arm portion 3 </ b> B and the wire 4 is fed out of the pulley 5. It is supposed to be. Although the detailed configuration will be described later, the pulley 5 is urged in the direction in which the wire 4 is wound (that is, the door 2 closing direction), and the wire 4 becomes a pulley as the vehicle door 2 moves in the closing direction. 5 is wound up.

The pulley 5 is connected to a clutch 6 for restricting the rotation of the pulley 5 and stopping the feeding of the wire 4. The clutch 6 is an electromagnetic clutch, and connection / disconnection of the clutch 6 is controlled by a clutch controller 7.

Each of the door holding switches 12A and 12B is configured as a push button, and is configured such that when the button is pressed once, the switch is turned on, and when the button is pressed twice within one second, the switch is turned off. The reason for pressing the button twice when the switch is turned off is to prevent the switch from being turned off against the intention of the door operator due to an erroneous operation or the like. Alternatively, the switch may be turned on and off. Further, the door holding switch 12B may be used also as a switch of another system such as a keyless operation system.

The ON signals of the door holding switches 12A and 12B are input to the ECU 20. Further, the door holding switches 12A and 12B are provided with LEDs (light emitting diodes) 12C and 12D, respectively, so that the LEDs 12C and 12D are turned on when the opening of the door 2 is restricted as described later. It has become.
That is, here, the lighting of the LED allows the door operator to visually recognize whether or not the opening of the door 2 is being restricted by the lighting of the LED, but the lighting of this LED is omitted. Alternatively, instead of the LED, other means for visually recognizing or means for aural recognition such as a buzzer may be used.

The door open / close sensor 8 is a sensor that detects the open / closed state of the door 2. Hereinafter, the door open / close sensor 8 is turned on when the door 2 is open. When the door opening / closing sensor 8 is on, an on signal is input to the ECU 20.
The obstacle sensor 9 is provided in the lower part of the door 2 on the vehicle rear side, and detects the approach of an obstacle that becomes an obstacle to the opening operation of the door 2. When the approach of the obstacle is detected, An ON signal is input to the ECU 20.

The configuration of the pulley 5 and the clutch 6 will be described in more detail. As shown in FIG. 3, both the pulley 5 and the clutch 6 have a shaft member 13 inserted therethrough. Ring-shaped ring portions 13A and 13B are formed at both ends of the shaft member 13, respectively, so as to prevent the pulley 5 and the clutch 6 from falling off the shaft member 13.
The pulley 5 includes a rotating member 5A, bushes 5B and 5F, a spring 5C, a cover member 5D, a torque transmission plate 5H, and a coil spring 5I. The rotating member 5A is rotatably attached to the shaft member 13 via the bushes 5B and 5F. A cover member 5D is provided so as to cover the rotating member 5A and the spring 5C.

The wire 4 is wound around the recess 5E of the rotating member 5A, and the wire 4 can be fed and wound according to the rotation of the rotating member 5A. The rotating member 5A is connected at one end to the other end of the spring 5C locked to the cover member 5D, and is always urged in the direction in which the wire 4 is wound (that is, the door 2 is closed) by the spring 5C. Yes.
A cylindrical fitting portion 5G is formed on the clutch 6 side of the rotating member 5A, and is inserted into a fitting groove 5J formed in the torque transmission plate 5H. The rotating member 5A and the torque transmission plate 5H are connected via a coil spring 5I, and the torque transmission plate 5H is urged toward the rotating member 5A by the coil spring 5I.

The torque transmission plate 5H is moved toward the clutch 6 when the clutch 6 is energized. However, the depth of the fitting groove 5J is not changed even if the torque transmission plate 5H is moved to a position where the torque transmission plate 5H contacts the clutch 6. The depth is such that torque can be sufficiently transmitted between the joint portion 5G.
The clutch 6 is fixed to the shaft member 13, and a friction surface 6A having a friction coefficient of a predetermined level or more is formed on the surface of the clutch 6 on the pulley 5 side.

When the clutch 6 is energized by the clutch controller 7, the torque transmission plate 5H moves to the clutch 6 side and contacts the friction surface 6A of the clutch 6, and the rotation of the torque transmission plate 5H is restricted, and the fitting portion 5G. The rotation of the rotating member 5A is regulated by the friction between the fitting groove 5J and the fitting groove 5J.
Here, the clutch 6 is configured to restrict the rotation of the rotating member 5A when the clutch 6 is energized regardless of the rotating direction of the rotating member 5A. That is, a one-way clutch that restricts only the rotation in the door opening direction) may be used.

Further, the rotation restricting force is limited to a predetermined value or less in consideration of an unexpected situation such as a malfunction, and when a rotational torque greater than the rotation restricting force is applied to the pulley 5, the friction surface 6A and the torque The transmission plate 5H or the fitting groove 5J and the fitting portion 5G slide so that the pulley 5 can rotate.
Here, the functional configuration of the ECU 20 will be described. As shown in FIG. 4, the ECU 20 receives ON signals from the door opening / closing sensor 8, the obstacle sensor 9, and the door holding switches 12A and 12B. In order to simplify the expression, the door holding switches 12A and 12B are illustrated as one switch, and the LEDs 12C and 12D of the door holding switches 12A and 12B are also illustrated as one.

  The ECU 20 is configured to transmit a clutch-on signal to the clutch controller 7 when the door opening / closing sensor 8 is on and the obstacle sensor 9 and / or the door holding switch are on. Yes.

Since the opening operation restricting device for an automobile door according to one embodiment of the present invention is configured as described above, the following operations and effects are achieved.
The operation mode of the ECU 20 and the clutch 6 will be described with reference to FIG. 5. At the time T0, only the door opening / closing sensor 8 is in an ON state. At this time, the clutch 6 is not energized and the opening of the door is not restricted.
When the door operator presses one of the door holding switches 12A and 12B at time T1, the door holding switch is turned on and an on signal is input to the ECU 20. At this time, the door opening / closing sensor signal is turned on and the door holding switch is turned on, and the ECU 20 transmits a clutch on signal to the clutch controller 7 to start energization of the clutch 6.

When the clutch 6 is sufficiently energized and the opening of the door 2 is sufficiently restricted, each LED 12C, to indicate that the opening operation control of the door 2 is on (that is, the opening of the door 2 is being restricted). 12D lights up.
When the clutch 6 is energized as described above, the rotation of the pulley 5 is restricted by the clutch 6 and the feeding of the wire 4 from the pulley 5 is restricted, and the arm portion 3B of the door checker 3 moves in the door opening direction. Therefore, the opening of the door 2 is restricted without being relatively displaced. At this time, when the door 2 is closed, the wire 4 is loosened, so that the door 2 is closed as usual, and the regulating force does not work.

  Next, at time T2, the door operator turns off the door holding switch signal by pressing any one of the door holding switches 12A and 12B twice within one second. When the door holding switch signal is turned off, the ECU 20 transmits a signal for stopping the energization of the clutch 6 to the clutch controller 7, and the energization of the clutch 6 is stopped. At this time, the restriction on the opening of the door 2 is released, and the lighting of the LEDs 12C and 12D is also stopped.

Thereafter, at time T3, the door holding switch signal is turned on again. The ECU 20 sends a signal to the clutch controller 7 to start energization of the clutch 6. When the opening of the door is sufficiently restricted, the LEDs 12C and 12D are lit.
At time T4, the door is completely closed and the door opening / closing sensor is turned off. The ECU 20 transmits a signal to the clutch controller 7 so as to stop energization of the clutch 6 after a predetermined time (1 to 2 seconds) from the time when the door open / close sensor signal is turned off.

  As described above, according to the automobile door opening movement restricting device according to the embodiment of the present invention, the wire 4 is connected to the door checker 3 that is generally provided in an automobile, The opening of the door 2 can be restricted at any door opening degree with a simple configuration including the pulley 5 that performs winding and the clutch 6 that restricts the rotation of the pulley 5. Further, when the door holding switch is turned on by the door operator with the door 2 opened, or when the obstacle sensor 9 detects the approach of the obstacle, the clutch 6 restricts the rotation of the pulley 5. By doing so, there is an advantage that the opening of the door 2 can be regulated with good responsiveness.

  Thus, for example, if the door holding switch is turned on when the door is manually opened to such an extent that the door operator does not come into contact with the obstacle, the door 2 and the obstacle can be obstructed even if the door operator does not hold the door. Contact with an object can be prevented. Further, even when the door operator does not recognize the obstacle, the obstacle sensor 9 detects the obstacle so that the opening of the door is automatically regulated, so that contact between the door and the obstacle is avoided. be able to.

Furthermore, even if the opening of the door 2 is restricted, the door 2 can be closed normally by the loosening of the wire 4, so that, for example, the vehicle travels on the side of the own vehicle on another vehicle, a bicycle, or the like. In such a case, the door 2 can be smoothly closed as necessary.
Further, if the door 4 is closed while the opening of the door 2 is restricted, the wire 4 remains slack, and the next time the opening of the door 2 is restricted, even if the rotation of the pulley 5 is restricted, the wire 4 A response delay occurs until the opening of the door 2 is restricted by the amount of slack. Therefore, in this embodiment, the pulley 5 is urged by the spring 5B in the direction in which the wire 4 is wound up (the direction in which the door 2 is closed), so that when the rotation restriction of the pulley 5 by the clutch 6 is released, the wire is automatically set. 4 is wound around the pulley 5 and the response delay due to the slack of the wire 4 can be prevented when the opening of the door 2 is restricted next time. In addition, when the clutch 6 is a one-way clutch, the wire 4 is always drawn from the pulley 5 by the length according to the opening degree of the door 2 without being loosened.

  Next, a modification of this embodiment will be described with reference to FIG. FIG. 6 is a cross-sectional view schematically showing the configuration of a pulley and a clutch according to a modification of the present embodiment. In the present modification, only the configuration of the pulley and the clutch is different from that of the above-described embodiment. As shown in FIG. 6, this modification is configured using a two-shaft pulley 14 and a clutch 15 instead of the pulley 5 and the clutch 6.

The pulley 14 and the gear 16A are arranged in series, and the shaft member 17 is inserted through the pulley 14 and the gear 16A. Ring-shaped ring portions 17A and 17B are formed at both ends of the shaft member 17, respectively, to prevent the pulley 14 and the gear 16A from falling off.
The pulley 14 includes a rotating member 14A, a spring 14B, and a cover member 14C. The rotating member 14A is rotatable with respect to the shaft member 17 via bushes 14E and 14F. A cover member 14C is provided so as to cover the rotating member 14A and the spring 14B.

  The wire 4 is wound around the concave portion 14D of the rotating member 14A, and the wire 4 is configured to be able to pay out and wind up according to the rotation of the rotating member 14A. Further, the rotating member 14A is connected at one end to the other end of the spring 14B locked to the cover member 14C, and is constantly urged in the direction in which the wire 4 is wound (that is, the door 2 is closed) by the spring 14B. Yes.

The clutch 15 and the gear 16B are arranged in series, and the shaft member 18 is inserted through the clutch 15 and the gear 16B. Ring-shaped ring portions 18A and 18B are formed at both ends of the shaft member 18, respectively, to prevent the clutch 15 and the gear 16B from falling off.
The gear 16B is formed with a disc portion 16C that rotates integrally. The gear 16B and the disc portion 16C are rotatable with respect to the shaft member 18 via the bushes 16G and 16H. The gear 16B meshes with the gear 16A and is configured to be able to transmit power between the gears 16A and 16B.

A cylindrical fitting portion 16D is formed on the clutch 15 side of the disc portion 16C, and is inserted into a fitting groove 16G formed in the torque transmission plate 16E. The disc portion 16C and the torque transmission plate 16E are connected via a coil spring 16F, and the torque transmission plate 16E is biased toward the disc portion 16C by the coil spring 5I.
The torque transmission plate 16E is moved to the clutch 15 side when the clutch 15 is energized. However, the depth of the fitting groove 16G is not changed even if the torque transmission plate 16E is moved to a position where it contacts the clutch 6. The depth is such that torque can be sufficiently transmitted between the joint portion 16D.

The clutch 15 is fixed to the shaft member 18, and a friction surface 15A having a friction coefficient equal to or higher than a predetermined level is formed on the surface of the clutch 6 on the disk portion 16C side.
When the clutch 15 is energized by the clutch controller 7, the torque transmission plate 16E moves to the clutch 15 side, the friction surface 15A of the clutch 15 and the torque transmission plate 16E come into contact with each other, and the rotation of the torque transmission plate 16E is restricted. Thus, the rotation of the disc portion 16C is regulated by the friction between the fitting portion 16D and the fitting groove 16G.

  Therefore, when the clutch 15 is energized by the clutch controller 7, the rotation of the gear 16B together with the disc portion 16C is restricted, and the rotation of the pulley 14 is also restricted via the gear 16A. Then, the feeding of the wire 4 is restricted, and the opening movement of the door 2 is restricted. In particular, according to this modification, the clutch 15 and the pulley 14 are connected via the gears 16A and 16B so as to be able to transmit power, so that the necessity of the clutch 15 is required by appropriately setting the gear ratio of the gears 16A and 16B. Therefore, it is possible to reduce the rotation restricting force and to use a cheaper or smaller clutch.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the spirit of the present invention.
For example, in the above-described embodiment, an obstacle sensor and a door opening / closing sensor are provided, but the sensors are not necessarily provided.
In the above-described embodiment, a predetermined door opening degree (pulley rotation angle) is stored in advance in the ECU, and when the door is opened to the stored door opening degree, the opening of the door is restricted by clutch-on. You may comprise as follows. In this way, for example, when the distance from the vehicle to the obstacle is almost constant, such as when parking frequently in the same parking lot, the door operator operates to turn on the door holding switch each time. The effect that it is not necessary is obtained.

  In the above-described embodiment, a minimum door opening that allows humans to enter and exit is set in advance, and the restriction on the opening of the door is prohibited until the minimum door opening is reached. May be. Specifically, the wire is slackened by an amount corresponding to the minimum door opening degree with the door completely closed. In this way, it is possible to prevent the passenger from being trapped in the vehicle due to malfunction.

  Further, in the above-described embodiment, the rotation restricting force of the pulley by the clutch (that is, the operation torque in the door opening direction when the door opening is restricted) can be set as appropriate. This rotation restricting force is determined by the door checker.
