Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door checker for a vehicle which applies a resistance to a door when the door is opened and closed to a predetermined opening when the door is opened and closed.

[0002]

2. Description of the Related Art A door of an automobile is provided with a door checker for imparting a braking force or a sense of moderation to the door when the door is opened to a predetermined degree to keep the door stationary. Although there is a mode in which a sense of moderation is given to a plurality of locations in the entire opening and closing range of the door, the moderation is given only when the door is opened at a certain angle. Therefore,
The door cannot be held stationary at any angle.

A door checker described in Japanese Patent Application Laid-Open No. 58-80079 has a check arm having a plurality of teeth formed by being pin-connected to a vehicle body, and a plunger operated by a solenoid incorporated in the door. The tip of the plunger is provided with teeth that mesh with the teeth. Actuating the plunger with the door open locks the door at any angle. In this door checker, when opening and closing the door, the door must be opened and closed while operating a switch for unlocking.

Japanese Utility Model Publication No. 5-18454 has a check arm which is pin-connected to a vehicle body, and a turning lever which is mounted on a door and applies a braking force to the check arm, and operates a door handle mounted on the vehicle body. Discloses a door checker in which the pressing force of the rotating lever against the check arm is released.

[0005]

In the door checker described in Japanese Patent Application Laid-Open No. 58-80079, the plunger is pressed against the check arm by electromagnetic force to lock the door. Since the tightening force of the solenoid depends on the electromagnetic force, the thrust of the solenoid that moves the plunger forward against the spring force is limited.
There is a limit to the braking force for locking the door and stopping at a predetermined opening. Moreover, if the door is locked at a predetermined opening, the door cannot be easily operated in the event of a malfunction of the lock mechanism.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a vehicle door checker which applies a predetermined resistance force to a door stopped at an arbitrary opening angle in a direction in which the door is opened and a direction in which the door is closed. is there.

[0007]

SUMMARY OF THE INVENTION Among the inventions disclosed in the present application, the outline of a representative one will be briefly described.
It is as follows.

That is, a vehicle door checker of the present invention has a checker arm rotatably mounted on a vehicle body and inserted into a door openably and closably mounted on the vehicle body. A vehicle door checker for applying resistance to a door, comprising: a press-contact member attached to the door and pressed against one surface of the checker arm; and a braking member disposed to face the press-contact member via the checker arm. A tightening member having an inclined surface for pressing the braking member toward the checker arm when applying a resistance force to the door, and limiting means for limiting a pressing force of the braking member against the checker arm. The braking force applied to the door is limited.

According to the present invention, a resistance or braking force can be applied to the opening and closing directions of the door in a state where the door is stopped at an arbitrary opening degree. Premature rotation is prevented. When a load exceeding the braking force is applied to the door, the door can be opened and closed. Therefore, even if a failure occurs in the mechanism for setting the checker operating state and the non-operating state, the predetermined opening degree is maintained. Can move the door that has been stopped.

Embodiments of the present invention will be described below in detail with reference to the drawings.

FIG. 1 is a view showing a part around a door of a vehicle to which a vehicle door checker according to an embodiment of the present invention is assembled.
Front door 12 for opening and closing the front seat side opening
Are mounted to be openable and closable via a predetermined number of hinges 13. A door checker 14 is provided between the pillar 11 and the door 12 to provide resistance to the door 12 in a state where the door is opened and closed to a predetermined opening degree when the door 12 is opened and closed.
Is provided. The door 12 is provided with a door inner handle 15 for releasing the door lock by a latch mechanism for holding the door 12 closed from the vehicle interior. The door 12 is locked or unlocked in the vehicle interior. For this purpose, a silcon knob 16 is provided.

FIG. 2 is an enlarged sectional view showing the door checker 14 shown in FIG. 1 on a plane side, and FIG. 3 is a partially omitted enlarged sectional view taken along line 2-2 in FIG. As shown in FIG.
The support pin 21 is parallel to the rotation center axis of the hinge 13. A checker arm 22 is rotatably attached to the support pin 21 at one end thereof.
The arm 22 is inserted between a door outer panel 12a and a door inner panel 12b that constitute the door 12. A checker section 23 is mounted in the door 12, and the arm 22 penetrates through the checker section 23. In order to regulate the fully open position of the door 12, the arm 22
A stopper 24 is provided at the other end of the door 12.
Is opened to the fully open position, the stopper 24 comes into contact with the checker portion 23.

The illustrated arm 22 has a width D shown in FIG.
3 are formed of a plate material having thickness dimensions d and d 'shown in FIG. 3, and both sides having a width dimension D are check surfaces 25 and 26. In the case shown in FIG. 26 is perpendicular to the support pin 21.

A holder 27 is provided on the door 12 with bolts 28.
The arm 22 penetrates a through hole 29 formed in the holder 27. A receiving groove 31 having a quadrangular cross section and opening on the check surface 26 of the arm 22 is formed in an upper portion of the arm 22 in the holder 27.
The accommodation groove 31 accommodates a metal roller 32 having a circular cross section for pressure contact, and the roller 32 comes into contact with the check surface 26 of the arm 22. A receiving groove 33 having a quadrangular cross section and opening to the check surface 25 of the arm 22 is formed in the lower portion of the arm 22 in the holder 27. Block 34
Is housed. In the case shown, the roller 32 constitutes a pressing member.

On the surface of the tightening block 34 facing the arm 22, an open-side inclined surface 35 extending in the longitudinal direction of the arm 22 and inclined toward the one end of the arm 22 in a direction approaching the arm 22 is provided. A closed inclined surface 36 is formed along the longitudinal direction of the arm 22 and in a direction approaching the arm 22 toward the other end of the arm 22. By these two inclined surfaces 35 and 36, a receiving recess 38 having a V-shaped cross section is formed in the tightening block 34 as shown in the drawing. They are arranged in parallel. The roller 37 constitutes a braking member that is arranged to face the roller 32 as a pressing member.

In the case shown in the figure, the closing-side inclined surface 36 is a first inclined surface that presses the roller 37 toward the checker arm 22 when applying a resistance force to the door 12 in the closing direction. And the open side inclined surface 35 is
The roller 37 is a second inclined surface that presses the roller 37 toward the checker arm 22 when a resistance force is applied in a direction in which the roller 37 is opened.

To move the tightening block 34 toward and away from the check surface 25 of the arm 22, the screw member 3
9 is screwed to the holder 27, and the screw member 39 is driven via a link mechanism 42 by a motor 41 as a driving means. Therefore, when the screw member 39 is rotated by the motor 41 so that the tip of the screw member 39 protrudes into the accommodation groove 33, the tightening block 34 approaches the check surface 25 and enters the check operation state. Conversely, when the screw member 39 is rotated in the opposite direction and is moved backward, the tightening block 34 is separated from the check surface 25 and the check is disabled.

By moving the tightening block 34 away from the arm 22, the gap between the two rollers 32 and 37 is set to the thickness d of the arm 22.
When the tightening block 34 is set in the check inoperative state until it is set to a larger value, the roller 37 is in the neutral position by its own weight, and the door 12 is moved from the fully closed position shown by the solid line in FIG. OK, door 1
No braking force is applied to 2, and the door 12 can be opened and closed lightly. In order to surely return the roller 37 to the neutral position by the magnetic force when the tightening block 34 becomes inoperative, a magnet may be embedded in the tightening block 34.

On the other hand, when the tightening block 34 is moved toward the check surface 25 by rotating the screw member 39 with the door 12 opened to an arbitrary opening, the tightening block 34 operates. Set to state.
When the door 12 is moved in the opening direction in this state, the roller 37 moves to the open side inclined surface 35 and the check surface 2 of the arm 22.
The roller 37 is pinched between the roller 37 and the roller 5, and the roller 37 is further tightened by the wedge action. As a result, the roller 37 fixes the arm 22 by a self-tightening action, and the door 12 is securely locked. Even when the door 12 is moved in the closing direction, the roller 37 is similarly sandwiched between the closed-side inclined surface 36 and the arm 22 so that the door 12 is closed.
Is locked.

Therefore, the door 12 can be locked at an arbitrary opening, and when the vehicle is stopped in a narrow space, when the door 12 is opened, the door 12 collides with an adjacent vehicle or another obstacle. Can be prevented. And door 1
2 can be strongly locked, so that even if the door 12 is opened on an uphill slope, the door 12 can be prevented from closing. Further, it is possible to prevent the door 12 from being carelessly closed by the strong wind with the door 12 opened. Further, when the occupant gets on and off the vehicle, the occupant can grasp the door 12 and use it as a support, thereby improving comfort when getting on and off the vehicle.

Rollers 32 and 37 as braking members
When the portion of the arm 22 having the thickness dimension d 'is located at the position shown in FIG.
4 is set to the operating state, the rollers 32 and 37 are set so that the wedge action does not work.
When the opening of the door 12 is small, the door can be smoothly opened and closed without receiving the action of the door checker.

To release the lock of the door 12 fixed at a predetermined opening, the screw member 39 is rotated to move the tightening block 34 away from the check surface 25 of the arm 22 in the vertical direction. At this time, tightening block 3
Since a force in the separating direction is acting on 4, the lock can be released with a small load.

As shown in FIG. 1, a door inner handle 15 is provided inside the door 12 to release a latch mechanism for holding the door 12 in a closed state in the vehicle interior. Motor 41
A check release switch for controlling the operation of the door inner handle 15 is interlocked with the door inner handle 15. When the check release switch is operated, the tightening block 34 is set to the inoperative position by the motor 41. On the other hand, when the hand is released from the release switch, the motor 41 is driven in the reverse direction, and the tightening block 34 moves closer to the operating position. In order to fulfill the same function, a check release switch 44 is also provided on the armrest 43 provided on the inner surface of the door 12, and a touch sensor switch 45 is provided inside the window pillar as a release switch.

FIG. 4 is a view showing the outer surface of the door 12. A door outer handle 46 for releasing the latch mechanism of the door 12 outside the vehicle is provided on the door 12, and the door outer handle 46 operates in conjunction with the door outer handle 46. The operation of the motor 41 is controlled by the release switch in the same manner as the release switch 44 described above.

Further, a touch sensor switch 47 is provided on a portion of the outer surface of the door 12 which is easily touched when the door is closed. If the switch 47 is touched while the door 12 is unlocked, the tightening block 34 is set to the non-operation state for a predetermined time by the timer, and the operation of the motor 41 is the same as the release switch 44. Is controlled. As a result, until the door is fully closed,
It is not necessary to touch the door, and the operability of closing the door is improved. When the hand touches the touch sensor switch 45, the touch sensor switch 47 operates similarly to the touch sensor switch 47.

If these release switches can be operated by a circuit for turning on the room lamp when the door 12 is opened, the motor 41 is operated even when the door 12 is fully closed. Will not work,
Even if the switch is operated during traveling, the operation of the tightening block 34 is prevented.

Although the illustrated door 12 is a driver's seat side door, a switch for driving the motor 41 and a checker section 23 are similarly provided for the passenger side door and the rear seat door.

If the checker is set to the inoperative state when the door 12 is opened and closed in this way, no tightening force acts on the arm 22, so that a resistance force, a braking force or a sense of moderation acts on the door 12. In addition, the door can be opened and closed lightly to an arbitrary position, so that the occupant can easily get on and off.

Adjustment screws 51 and 52 are screwed to the holder 27 on both sides of the roller 37. When the door 12 is moved in the opening direction indicated by the arrow O in FIG. 3 in a state where the tightening block 34 is set to the operating state, the adjusting screw 51
Regulates the amount of movement of the roller 37 toward one end of the arm 22 due to contact with the arm 22. When the door 12 is moved in the closing direction indicated by the arrow C, the adjustment screw 52 regulates the amount by which the roller 37 comes into contact with the stopper surface 54 and moves toward the other end of the arm 22. The stopper surfaces 53 and 54 of the adjustment screws 51 and 52 constitute resistance force limiting means for limiting the pressing force of the roller 37 against the arm 22 to limit the resistance force.

By restricting the amount of movement of the roller 37 in this manner, the amount of engagement of the roller 37 is restricted, and the door 1 can be locked without locking the door 12 to the arm 22.
When the door 2 is stopped at an arbitrary position, a predetermined sliding force, that is, a sense of moderation can be given to the door 12. Accordingly, when an opening / closing force exceeding the slip resistance is applied to the door 12 in a state where the door 12 is stopped, the door 12 can be opened and closed. Therefore, even if a malfunction occurs in the mechanism for disabling the tightening block 34, if a force exceeding the braking force applied to the door 12 is applied to the door 12, the door 12 is opened and closed.

If the gap between the adjusting screw 51 and the roller 37 when the roller 37 is in the neutral position and the gap between the adjusting screw 52 and the roller 37 are set to be the same, the roller 37 is engaged. The same slip resistance is applied to the door 12 in the opening direction and the closing direction of the door 12 in the open state. On the other hand, by making the gap between the roller 37 and the adjusting screw 51 at the neutral position different, the slip resistance in the direction in which the door 12 is closed and the slip resistance in the direction in which the door 12 is opened are made different from each other. Can be.

FIG. 5 is a graph schematically showing a change in slip resistance when the braking force in the closing direction is higher than the braking force in the opening direction, that is, the slip resistance in the closing direction.
This graph shows a case where the door 12 is opened and closed while the fastening block 34 is set at the operating position, unlike the normal door opening and closing operation. As shown in FIG. 5, the slip resistance of the door 12 when it is closed is set to be greater than when the door 12 is opened with the tightening block 34 in the operating state, thereby making the door 12 more difficult to close when the checker is operated. be able to.
Thereby, it is possible to improve the getting-off property under the state where the checker is operated. In the case shown, the door 12 can be opened when a load of 5 kg or more is applied, for example, when the checker is operated, and can be closed when a load of 10 kg or more is applied, for example.

In order to make the braking force different between the opening direction and the closing direction, as described above, the adjustment screws 51 and 52 may be operated to make the amount of movement of the roller 37 different. The inclination angles of the inclined surface 35 and the closed inclined surface 36 may be different from each other.

FIG. 6 is a view showing a portion similar to that of FIG. 3 in a vehicle door checker according to another embodiment. In this figure, members common to those shown in FIG. 3 are denoted by the same reference numerals. Is attached.

In this checker, the roller 32 is not provided on the holder 27 above the arm 22, and the holder 27 itself comes into contact with the check surface 26 of the arm 22. The roller 37 for clamping the arm 22 by the holder 27 is formed by a metal core portion 37a and an outer shell portion 37b made of hard rubber or plastic on the outer periphery thereof, as shown in the figure. Is added, elastic deformation occurs. To operate the tightening block 34, a rod 55 is provided on the holder 27 so as to be slidable in the axial direction.
a. When the solenoid 56 is not energized, the tip of the rod 55 comes into contact with the inclined surface 57a and the tightening block 34 is in the inoperative position as shown in the figure, but when the solenoid 56 is energized,
The actuator 57 projects to the position shown by the two-dot chain line in FIG. 6, and the tightening block 34 is in the operating position.

FIG. 7 is a view showing a vehicle door checker according to another embodiment of the present invention. An opening-side inclined surface 35 is formed on a tightening block 34, and a roller 37 is mounted on the holder 2.

The stopper 27 is formed on the holder 27 for setting the amount of movement of the roller 32.

As shown, a groove 61 having a T-shaped cross section is formed in the tightening block 34, and a large-diameter head 62 that engages with the groove 61 is provided at the tip of the screw member 39. . Therefore, when returning the tightening block 34 from the operating position to the non-operating position, when the screw member 39 is rotated, the tightening block 34 is driven by the movement of the screw member 39 without using its own weight. In this way, the tightening block 34 can be reliably driven.

FIG. 8 is a view showing a vehicle door checker according to still another embodiment of the present invention.
Arm members 22a and 22b,
A spacer 63 is attached between these arm members, and respective rollers 32 and 37 are arranged so as to face the spacer 63. In this case, a stopper surface 53 is formed on the tightening block 34, and in the case shown in FIG.
While being offset along the longitudinal direction of the
They are arranged facing each other at substantially the same position.

In the case shown in FIG. 8, a receiving plate 64 that contacts the tip of the screw member 39 is disposed in the receiving groove 33, and a space between the receiving plate 64 and the tightening block 34 is made of rubber or the like. An elastic member 65 is provided. The spring force of the elastic member 65 urges the arm 22 through the roller 37 when the tightening block 34 is operated. Without using rubber as the elastic member 65,
A leaf spring may be used, and the elastic member 65 may be incorporated in the checker of the above-described embodiment.

In the vehicle checker shown in FIGS. 7 and 8, the slip resistance when the door 12 is opened and the slip resistance when the door 12 is closed differ depending on the positions of the stopper surfaces 53 and 54. Can be
Further, it is possible to set the characteristics of the slip resistance as shown in FIG.

In the vehicle checker shown in FIGS. 7 and 8, the position of the stopper surface 54 and the height of the through hole through which the arm 22 passes are set to predetermined dimensions, and the tightening block 34 is in an inoperative state. When the door 12 is moved in the closing direction at the time of, the wedge function of the roller 32 is invalidated and the arm 22 is not locked.

FIG. 9 is a diagram showing, as a comparative example, a vehicle door checker according to the related art of the present invention.
Inside, blocks 71 and 72 are arranged on both sides of the arm 22, and a roller 73 is arranged between one block 71 and the arm 22. Further, the inclined surface 7 into which the roller 73 bites when the door 12 is moved in the opening direction.
4 are formed in the block 71. A spring force in a direction toward the inclined surface 74 is urged by the compression coil spring 75 to the roller 73, and the return member 7 is pushed back to push the roller 73 cut between the inclined surface 74 and the arm 22.
6 are provided.

Next, the opening and closing operation of the door to which the above-described vehicle checker of the present invention is applied will be described in comparison with the related art shown in FIG.

When opening the door 12, one of the plurality of checker release switches is operated. Door 1
When the door 2 is opened in this state, the sliding resistance force is not applied to the arm 22, and the door 12 is rotated slightly. can do. When the user releases the checker release switch with the door 12 opened to an arbitrary opening degree or the timer is operated, the motor 41 moves the tightening block 34 to the operating position. Contact

In this state, when the door 12 is moved in the opening direction, the roller 3 is moved between the open side inclined surface 35 and the arm 22.
7 digs into the door 12 and is locked. Even when the door 12 is moved in the closing direction, the door 12 is similarly locked. In the case shown in FIG. 9, when the door is moved in the closing direction, the roller comes off and the door cannot be locked, but in the checker of the present invention, the movement of the door in both the open and closed directions is locked. Therefore, the door is prevented from being moved carelessly. In addition, the occupant can get on and off using the door as a support.

When one of the release switches is operated to close the door 12 having the predetermined opening, the motor 41 is driven to return the tightening block 34 from the operating position to the inactive position. That is, the door can be rotated lightly. When the tightening block 34 is returned, it is moved in a direction perpendicular to the check surface of the arm 22. Therefore, if the tightening block 34 is moved with a small moving force and by a small stroke, it can be returned to the inoperative position. Can be. In the case shown in FIG. 9, since the roller must be moved against the frictional resistance between the inclined surface and the arm, it is necessary to apply a large moving force to the roller for unlocking.

When the door 12 is closed from outside the vehicle, when the release switch 47 is touched by a hand, a timer is activated and the checker is inactive for a predetermined time.
, The door 12 can be closed by inertia or inertia. When the latch mechanism for holding the door in the closed state is operated to be in the full latch state, the checker is set to the inoperative state.

Next, a case will be described in which the amount of rolling movement of the roller 37 is regulated by the stopper surface, and a predetermined slip resistance is applied to the door 12 when the checker operates.

When the door 12 is opened and closed, as described above, the tightening block 34 is in the inoperative position, and can be opened and closed lightly only by applying a small turning force to the door. When the door 12 is stopped at an arbitrary position, the checker operates and the roller 37 comes into contact with the check surface of the arm 22. In this state, the rolling movement, that is, the biting movement of the roller 37 is restricted, so that when a force greater than the slip resistance applied by the roller 37 is applied to the door 12, the door 12 can be opened and closed. The slip resistance is set so as to give the door 12 a predetermined moderation feeling.

If the slip resistance is made different between the direction in which the door 12 is opened and the direction in which the door 12 is closed, it is possible to achieve both improvement in getting off the vehicle and maintenance of safety. Also, as shown in FIG. 5, when the sliding resistance in the direction in which the door 12 is closed is set to be larger than the sliding resistance in the direction in which the door 12 is opened, it is possible to get out of the vehicle while supporting the door and raising the body even on an upward slope. In addition, when the door is opened from outside the vehicle in the event of an accident, the door can be opened with a small force.

Although the invention made by the inventor has been specifically described based on the embodiment, the invention is not limited to the above-described embodiment and can be variously modified without departing from the gist of the invention. Needless to say, there is.

For example, a ball may be used instead of the rollers 32 and 37. Further, the fastening member 34
As a driving means for operating the actuator to the operating position and the inoperative position, a hydraulic cylinder which operates by air pressure or hydraulic pressure may be used instead of the motor 41 or the solenoid 56.
