Description

  The present invention relates to a device that assists an opening operation of a door by a door operator by automatically releasing the engagement of the door of the vehicle and slightly opening the door of the vehicle.

In recent years, if the door operator is carrying the key, the door automatically moves by performing a predetermined door unlocking operation such as touching the outside handle of the automobile door (door) for a predetermined time or more. A keyless operation system that is unlocked (unlocked) has been developed and put into practical use.
According to this technology, the door operator only carries the key (key) and the door is unlocked without actually holding the key. For example, when unlocking the door operator, And the trouble of taking out the key from the pocket of clothes or the like can be eliminated.

However, since the doors are only unlocked automatically in the prior art as described above, when the door is actually opened, the door operator pulls the door's outside handle, etc. It is necessary to release the engagement of the combined mechanism (hereinafter referred to as a door latch).
In order to eliminate the need for the door operator to manually disengage the door latch after the door is automatically unlocked in this way, in addition to automatically unlocking the door, the door latch You can cancel automatically.

However, it is difficult for the door operator to visually grasp that the door latch is disengaged if the door latch is disengaged automatically by simply disengaging the door latch.
Also, if the door operator does not notice or delays being aware of it even after the door latch is automatically disengaged, for example, the door moves in the closing direction due to wind or inclination, and the door latch is engaged again. Or, it may be in a half-engaged (half) state.

Therefore, in order to facilitate an appropriate door opening operation by the door operator, it is conceivable to automatically release the engagement of the door latch and open the door by a predetermined opening degree (hereinafter, referred to as “fine opening”).

That is, here, when the door operator touches the outside handle 105 for a predetermined time (for example, 1 second), the keyless operation switch 105a provided in the outside handle 105 is turned on as the door opening operation is performed. Thus, a keyless operation operation signal is input to the ECU 106. The door opening operation is not limited to touching the outside handle 105 for a predetermined time as described above, and can be set as appropriate.

The output terminal of the ECU 106 is connected to the motors of the release actuator 103 and the key drive actuator 108, and the supply of electric power from the power source is adjusted by the ECU 106 so that the operation of the actuators 103 and 108 is controlled.

For this authentication device, a known device may be used. Here, when an input of a keyless operation operation signal is received, the ECU 106 transmits a radio wave for key confirmation, and whether or not the door operator carries the key. It comes to judge.

(Door latch and release actuator)
Here, the structure of the door latch part 102 and the release actuator 103 is demonstrated in detail. As shown in FIG. 3, the door latch portion 102 includes a door latch 1, a key lock member 2, a key cylinder 3, a link member 4, a lock rod 5, a lock cable 6, an open rod 7, and an open cable 8. The release actuator 103 includes an arm portion 103A as a movable portion. The arm portion 103A is connected to the link member 4 of the door latch portion 102 via the link member 9, and the link members 4 and 9 are connected to the shaft portion 10. It is possible to rotate integrally with the center. A wire 107 is connected to the arm portion 103A.

The release actuator 103 includes a motor (not shown) inside, and is configured to swing and drive the arm portion 103A to a predetermined latch opening position and a latch closing position in accordance with a drive signal transmitted from the ECU 106. .
The link member 4 includes two arm portions 4A and 4B, and the arm portion 4A is connected to an open cable 8. The open cable 8 is connected to an inside handle (not shown) attached to the inner side surface of the door 101, and the link member 4 is rotated when the door operator pulls the link member 4 through the inside handle and the open cable 8. It is configured.

The key lock member 2 is rotatably attached to a key lock position and a key unlock position about the shaft portion 2A.
The key lock member 2 is always urged by a return spring (not shown) to the key unlock position side when unlocked and to the lock position side when locked.

The key lock member 2 is configured to rotate to the key lock position by being pulled by the lock rod 5 or the lock cable 6 according to the operation of the key cylinder 3 and the inside handle. In addition, about the lock rod 5, you may comprise using a cable instead of a rod (bar-shaped member).

  The door latch 1 is composed of a claw (lock latch, latch) 1A and a pole (ratchet) 1B. When the door 101 is closed, the door latch 1 is provided in the vehicle body 100 in a gap between the claw 1A and the pole 1B. The door latch 1 is engaged with the striker by engaging the claw 1A and the pole 1B with the striker (engagement portion) not to be inserted.

  The door latch 1 is connected to be able to transmit power from the arm 4B of the link member 4 via a power transmission mechanism (not shown). That is, when the link member 4 rotates in the direction indicated by the arrow a in the figure, the arm 4B also rotates, and the pole 1B rotates in the counterclockwise direction indicated by the arrow c. This disengages the pole 1B, and the claw 1A rotates in the direction indicated by the arrow b in the figure. The claw 1A is urged so as to rotate in the direction of disengagement by a return spring (not shown). Thus, the engagement of the door latch is released by releasing the striker by rotating the claw 1A.

(Door open mechanism)
Next, the door fine opening mechanism will be described with reference to FIGS. 4A to 4C are shown upside down from FIG. 1 for ease of explanation.
As shown in FIG. 4A, the door fine opening mechanism 104 includes a cover member 11, a link member 12, a protrusion rod (protrusion member) 13, an absorption spring (elastic member) 14, and a return spring 15.
A wire 107 is inserted into the cover member 11 so as to be able to advance and retract, and an end portion of the wire 107 is connected to the link member 12. The link member 12 has a shaft portion 12A fixed to the cover member 11 so as to be rotatable about the shaft portion 12A. One end of the link member 12 is inserted into a notch hole 13B of the protruding rod 13.

  The protruding rod 13 has a tip portion inserted through the cover member 11 so as to be able to advance and retreat relative to the vehicle body 100. Further, a disk-shaped enlarged diameter portion 13A is formed near the center of the protruding rod 13 so as to be displaced integrally with the protruding rod 13. The displacement amount (stroke) ΔL in the advancing / retreating direction of the protruding rod 13 takes into consideration the spring force of the absorption spring 14 so that the door 101 is opened (ie, slightly opened) by a predetermined opening amount Q as will be described later. Is set.

Further, as shown in FIG. 4D, a notch hole 13B formed long in the longitudinal direction of the protruding rod 13 is formed in the base end portion of the protruding rod 13, and is inserted into the notched hole 13B. The link member 12 is configured to be able to be displaced to the advance position or the retract position of the protruding rod 13 by the length in the longitudinal direction of the notch hole 13B.
An absorption spring 14 is disposed on the proximal end side of the enlarged diameter portion 13A of the protrusion rod 13 so as to be loosely fitted around the protrusion rod 13, and one end of the absorption spring 14 contacts the link member 12. The other end is in contact with the enlarged diameter portion 13A. As a result, the link member 12 and the protruding rod 13 are connected to each other so as to be able to transmit power via the absorption spring 14, and the protruding output transmitted from the link member 12 (force applied in the direction in which the protruding rod 13 advances). Is transmitted to the protruding rod 13 through the absorbing spring 14.

  For this reason, when operating the protrusion rod 13 by the link member 12, the operating force (protrusion output) input from one end of the link member 12 is blunted by the amount of contraction of the absorption spring 14 and transmitted to the protrusion rod 13. Although the power transmission loss occurs, the absorption spring 14 functions when the door 101 cannot be opened when the link member 12 is operated due to, for example, a malfunction in the door latch 1.

  That is, the case where the door 101 cannot be opened is a case where the relative displacement between the door 101 and the vehicle body 100 is impossible, and even if the protruding rod 13 protrudes, the vehicle body 100 at the tip thereof becomes a wall that does not move. In such a case, if the operating force of the link member 12 is directly applied to the protruding rod 13, an excessive axial force or tensile force is applied to the operating force transmission system including the protruding rod 13 and the link member 12, and the operating force There is a risk of damage to the transmission system. Therefore, an absorption spring 14 is interposed between the link member 12 and the protruding rod 13, and in such a case, the relative force between the link member 12 and the protruding rod 13 is absorbed while absorbing the operating force of the link member 12. The displacement, that is, the mode in which the protruding rod 13 does not move even if the link member 12 moves is allowed. In this case, the axial force or tensile force applied to the operating force transmission system is suppressed to the level of the spring force generated by the absorption spring 14.

That is, here, the wire 107, the link member 12, the absorption spring 14, and the protruding rod 13 function as a compression force absorbing mechanism.
Therefore, it is desirable that the absorbing spring 14 is as stiff as possible from the viewpoint of operating the protruding rod 13 by the link member 12 (the spring constant Ka is large). However, if attention is paid to the function of the absorbing spring 14 itself, the door It is desirable to suppress the rigidity (the spring constant Ka is not excessively large) to such an extent that the operating force transmission system can be protected with some margin when the opening 101 cannot be opened. From such a viewpoint, the rigid characteristic (spring constant Ka) of the absorption spring 14 is set.

A return spring 15 is disposed on the distal end side of the enlarged diameter portion 13A of the protruding rod 13 so as to be loosely fitted around the protruding spring 13, and one end of the return spring 15 contacts the enlarged diameter portion 13A. The other end is in contact with the cover member 11.
The return spring 15 is a direction in which the protruding rod 13 moves backward so that the protruding rod 13 is in a retracted position (a position where the protruding amount of the protruding rod 13 from the cover member 11 becomes the reference protruding amount Lc when the door is closed). Anti-protruding direction: force in the direction opposite to the protruding direction). The retraction position of the protrusion rod 13 (reference protrusion amount Lc) is set to such an extent that the tip of the protrusion rod 13 does not come into contact with the vehicle body 100, and the protrusion rod 13 is shown in a normal state when the operating force of the link member 12 is not applied. The stopper is not held and the urging force of the return spring 15 holds the retracted position.

  Such a return spring 15 exhibits a biasing force that resists the force for operating the protruding rod 13 by the link member 12, and is therefore as soft as possible from the viewpoint of operating the protruding rod 13 by the link member 12 (spring It is desirable that the constant Kr is small), but the rigidity of the return spring 15 original function, that is, the rigidity that can exert the urging force that can hold the protruding rod 13 in the retracted position at the normal time is secured (the spring constant Kr is excessive). It is desirable not to be small. From this point of view, the rigid characteristic (spring constant Kr) of the return spring 15 is set.

  In order to effectively perform the advance (protrusion) operation and the retreat operation of the protrusion rod 13, the return spring 15 has a softer characteristic than the absorption spring 14, that is, the spring constant Kr of the return spring 15 is set to the absorption spring 14. It is preferable to set it to be smaller than the spring constant Ka of (Kr <Ka).

(Function and effect)
Since the opening operation assisting device for an automobile door according to an embodiment of the present invention is configured as described above, the following operations and effects are achieved.
As shown in FIG. 5, when the door operator contacts the outside handle 105 for a predetermined time or more with the automobile door 101 locked (locked), a keyless operation operation signal is input from the outside handle 105 to the ECU 106 (T1). At the time, the ECU 106 authenticates whether or not the door 101 can be unlocked by the authentication device.
When it is authenticated that the door operator has the key, the ECU 106 transmits an unlock signal to the key drive actuator 108 and transmits a drive signal to the release actuator 103. Then, in response to the unlock signal, a motor (not shown) of the key drive actuator 108 is driven (at time T2), whereby the key lock member 2 is rotated to the key unlock position and the automobile door 101 is unlocked.

  On the other hand, the release actuator 103 receives the drive signal, and the arm portion 103A starts to rotate from the latch closed position to the latch open position (at time T3), and the link member 4 is moved by the arrow a in FIG. Rotate in the direction. Then, the claw 1A and the pole 1B of the door latch 1 are rotated in the directions of arrows b and c via the arm portions 4B of the link member 4, respectively, and the engagement of the door latch 1 is released (at time T4).

Further, at time T3, the arm 103A of the release actuator 103 is rotationally driven, whereby a tensile force is applied to the wire 107. As shown in FIG. 4B, the link member of the door fine opening mechanism 104 is generated by this tensile force. 12 is rotated.
The distal end of the link member 12 is displaced in the advancing direction (advance position) of the protruding rod 13, and a protruding output (compression force) is transmitted to the protruding rod 13 through the absorption spring 14. As a result, the protruding rod 13 advances from the cover member 11 and comes into contact with the side sill or B pillar (both not shown) of the vehicle body 100. Further, when the protruding rod 13 further advances, the automobile door 101 including the protruding rod 13 is biased in the opening direction by the reaction from the vehicle body 100, and the automobile door 101 is opened by a predetermined door opening amount Q (T5). Time).

Here, for example, the operation when the door 101 for the automobile cannot be opened due to some inconvenience such as the incomplete release of the door latch 1 or the presence of an obstacle outside the door 101 for the automobile will be described.
As shown in FIG. 4C, in a state where the automobile door 101 cannot be opened due to some trouble, the door 101 does not open even if the tip of the protruding rod 13 abuts against the vehicle body 100, so that the protruding rod 13 protrudes further. Impossible. At this time, the absorption spring 14 contracts due to the axial force transmitted from the wire 107 to the absorption spring 14 via the link member 12. That is, even when the protruding rod 13 cannot be displaced, the link spring 12 is displaced to the advanced position by contraction of the absorption spring 14, that is, the relative displacement between the link member 12 and the protruding rod 13 is allowed.

  As described above, according to the automotive door opening operation assisting device according to the embodiment of the present invention, the door operator 101 touches the outside handle 105 in a state of holding the key for a predetermined time or more, thereby allowing the automotive door 101 to be touched. And unlocking of the door latch 1 can be automatically performed. As a result, the door operator can visually and sensibly understand that the engagement of the door latch 1 has been released, and the door 101 can be opened easily and appropriately.

Further, since the door 101 is slightly opened by utilizing the engagement release operation of the door latch 1 driven by the release actuator 103 which is an actuator for releasing the engagement of the door latch 1, an actuator for slightly opening the door is newly provided. It is possible to release the engagement of the door latch 1 and slightly open the door 101 with a single actuator.
Further, even when the door 101 cannot be opened due to an obstacle or the like, an excessive axial force (compression force or tensile force) is prevented from being generated in the operation system member of the protrusion rod 13, and the protrusion rod 13 or It is possible to prevent damage or the like from occurring at a location where the projecting rod 13 of the vehicle body 100 contacts.

  Further, when the door 101 cannot be opened, the protruding rod 13 cannot be displaced, but since the link member 12 can be displaced by contraction of the absorption spring 14, it is possible to prevent the arm portion 103A of the release actuator 103 from being unable to rotate, For example, problems such as damage to the motor due to idle rotation of the motor of the release actuator 103 can be avoided, and the disengagement operation of the door latch 1 is not hindered.

  The point of preventing the engagement of the door latch 1 from being hindered will be described in more detail. In this embodiment, the release actuator 103 is driven to simultaneously perform the door latch 1 disengagement operation and the door fine opening operation. There is a state where the engagement release of the door latch 1 is not completed even when the door fine opening operation (protrusion of the protruding rod 13) by the opening mechanism 104 is started (see the period from T3 to T4 in FIG. 5).

In such a case, since the door latch 1 is in the engaged state, the door 101 cannot be opened and the protrusion rod 13 cannot protrude even if a protrusion output is applied to the protrusion rod 13.
At this time, if the relative displacement between the link member 12 and the protruding rod 13 is not allowed due to the contraction of the absorption spring 14, the link member 12, the wire 107, and the arm portion 103A of the release actuator 103 cannot be displaced, and are connected to the arm portion 103A. It is considered that the link member 9 and the link member 4 that have been rotated cannot be rotated, and the engagement releasing operation of the door latch 1 is hindered.

  However, since the link member 12 can be displaced by contraction of the absorption spring 14, it is possible to prevent the disengagement operation of the door latch 1 from being hindered without inhibiting the rotation of the arm 103A of the release actuator 103. Can do. When the disengagement of the door latch 1 is completed, the protruding rod 13 is protruded by the biasing force of the contracted absorption spring 14, and the door 101 can be slightly opened.

  After the door 101 is opened to the predetermined opening Q (at time T5 in FIG. 5), the driving force of the release actuator 103 is turned off, so that the protruding amount of the protruding rod 13 is determined by the urging force of the return spring 15. Since the protrusion amount Lc is obtained, when the door 101 is closed, the tip of the protruding rod 13 does not interfere with the closing movement of the door 101 due to contact with the vehicle body 100 and the like, and a good door closing property can be secured. Can also be obtained.

(Modification)
Next, a modification of the present invention will be described with reference to FIG. FIG. 6 is a view for explaining an opening operation assisting device for an automobile door according to a modification of the present invention, and FIGS. 6A to 6C schematically show the structure of the compression force absorbing structure. FIG.

As shown in FIG. 6A, in this modification, an arm member 20 that is rotatable about the shaft portion 10 is disposed, and the wire 107 is connected to the arm member 20, and the link member 9 and the arm member 20 are connected. Are different from those of the embodiment in that each rotational force can be transmitted via the connecting spring 21. Although not shown here, the absorbing spring 14 of the door fine opening function 104 is omitted, and the projecting output (compression force) is directly transmitted from the link member 12 to the projecting rod 13. Is different.

The link member 9 and the arm member 20 are configured such that the rotational force is transmitted only through the connecting spring 21. With the exception of the connecting spring 21, the link member 9 and the arm member 20 rotate independently of each other. It is supposed to be.
The spring constant (spring force) Kc of the connecting spring 21 transmits the rotational force of the link member 9 to the arm member 20 so that the door 101 is opened by a predetermined opening degree from the arm member 20 via the wire 107 and the link member 12 ( That is, it is possible to apply a projecting output (compression force) sufficient for fine opening) to the projecting rod 13, and when an excessive compressive force exceeding the reference is applied to the projecting rod 13, the connecting spring 21 contracts. By absorbing the relative displacement between the arm member 20 and the link member 9, it is set to a value that can absorb the compressive force generated in the protruding rod 13. That is, here, the link member 9, the arm member 20, the connecting spring 21, the wire 107, the link member 12, and the protruding rod 13 function as a compression force absorbing mechanism.

  Thus, according to the automobile door opening operation assisting device according to the modification of the embodiment of the present invention, the door operator holds the key in the state where the door operator holds the key as in the embodiment, for a predetermined time or more. By unlocking, the door 101 for the automobile is automatically unlocked. Further, as shown in FIG. 6B, when the arm portion 103A of the release actuator 103 is rotationally driven from the latch closed position to the latch open position, the link member 4 rotates and the engagement of the door latch 1 is released. .

  At this time, the rotational driving force of the arm portion 103A of the release actuator 103 for releasing the engagement of the door latch 1 is transmitted to the arm member 20 via the connecting spring 21, and the arm member 20 is rotated by the rotational driving force to be released. Since the rotational driving force of the actuator 103 is transmitted to the door fine opening mechanism 104 to slightly open the door 101, the door latch 1 can be disengaged and the door 101 can be slightly opened without newly providing a door fine opening actuator. It can be done automatically. As a result, the door operator can visually and sensibly understand that the engagement of the door latch 1 has been released, and the door 101 can be opened easily and appropriately.

  Further, when the door 101 cannot be opened due to an obstacle or the like, the protrusion rod 13 cannot be protruded, and the protrusion rod 13, the link member 12, the wire 107, and the arm member 20 cannot be displaced. Since the link member 9 can be displaced by contraction of the connecting spring 21 as shown in FIG. 6C, an excessive compressive force generated in the protruding rod 13 is absorbed even when the door 101 cannot be opened, It is possible to prevent damage to the protruding rod 13 and the portion of the vehicle body 100 that contacts the protruding rod 13. Further, it is possible to prevent the arm portion 103A of the release actuator 103 from rotating and avoid problems such as damage to the motor of the release actuator. Furthermore, since each link member 4 and 9 can also rotate, it can prevent that the engagement release operation | movement of the door latch 1 is inhibited.
