Description

[Detailed description of the invention] (Industrial application field) The present invention relates to an improvement in an opening/closing device for an automobile door.

(Prior Art) Conventionally, automatic opening/closing devices for automobile doors have been proposed that are equipped with an opening/closing mechanism that opens and closes the door using an actuator (see Japanese Utility Model Publication No. 45-8562...
Prior art A).

In addition, in order to reduce the impact caused by forcefully closing the door and ensure door closing, a striker on the vehicle body rotates the door lock latch from the half-lock position to the full lock position. A device equipped with a closing mechanism (door closing device) that rotates the door with an actuator to perform the closing operation has also been proposed (U.S. Patent No. 3).
See Publication No. 989287...Prior art B).

Further, an automatic door opening/closing device that combines the above-mentioned opening/closing mechanism and a tightening mechanism (auxiliary closing device) has also been proposed (see Japanese Patent Publication No. 1-12912...Prior Art C).

(Problem to be Solved by the Invention) In the case of the above-mentioned prior art B, when the door is closed, the locking mechanism is operated from a position where a striker on the vehicle body rotates the latch of the door lock to a bar float position to a full lock position. However, the tightening mechanism will not start operating unless the latch is rotated to the half-lock position with the striker, so the door must be closed with some force, and the degree of this will vary depending on the car model. However, because it is very difficult to understand visually, the striker often rotates the latch to the full lock position, that is, closes the door vigorously until the door is completely closed, and the tightening mechanism is effectively The problem is that it does not fulfill its function.

Further, in the case of the above-mentioned prior art C, there is also a problem that the closing mechanism cannot substantially perform its function because the opening/closing mechanism must operate the door with some force to close the door.

The present invention was made to solve the above problems, and
The purpose of this invention is to eliminate the need to forcefully close the door by starting the operation of the tightening mechanism from the position where the striker contacts the latch when the door is closed.

(Means for Solving the Problems) Therefore, the present invention provides an automobile door opening/closing device equipped with a tightening mechanism for tightening a door lock latch using an actuator, in which the tightening mechanism is operated when the door is closed. ,
This is characterized in that the striker on the vehicle body is operated from the position where it contacts the latch of the door lock to the full lock position.

Furthermore, in an automobile door opening/closing device that includes an opening/closing mechanism that opens and closes the door using an actuator and a tightening mechanism that tightens and operates a door lock latch using an actuator, the opening/closing mechanism can move the door between the fully open position and the fully open position. The locking mechanism is operated between the closed positions, and the tightening mechanism is operated from the position where the striker on the vehicle body contacts the latch of the door lock to the full locking position when the door is closed. .

(Operations and Effects of the Invention) The present invention operates a tightening mechanism for tightening the door lock latch using an actuator from the position where the striker contacts the launcher to the full lock position when the door is closed. It is.

Therefore, since the tightening mechanism starts operating from the position where the striker contacts the latch, it is only necessary to push the door lightly, and there is no need to forcefully close the door.

As a result, the impact when the door is closed is further alleviated, the timing at which the tightening mechanism starts operating is brought forward, and the function of the tightening mechanism is fully exerted, so that the door can be closed reliably.

On the other hand, in addition to the tightening mechanism, an opening/closing mechanism for opening/closing the door using an actuator is provided;
Even when the door is operated between the fully open and fully closed positions, there is no need for the opening/closing mechanism to forcefully close the door, which further reduces the impact when the door is closed, and also prevents the closing mechanism from operating. The start timing is earlier, the function of the tightening mechanism is fully demonstrated, and the door can be closed reliably.

(Embodiments) Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIG. 1, the front end of the automobile side door IO is attached to the vehicle body 11 via a hinge mechanism (not shown) so that it can be opened and closed, and the rear part of the door 10 is attached to the vehicle body when the door is closed.
A door lock (lock mechanism) 12 for locking the door 1 is attached.

Note that 13 is a window glass.

At the front of the door IO, an actuator (
An opening/closing mechanism 14 which is operated by an electric motor 21) is attached, and a tightening aWi 15 which is operated by an actuator (electric motor 62) to tighten a latch 69 (described later) of the door lock I2 is attached to the rear of the door 10. ing.

The opening/closing mechanism 14 operates the door 10 between the fully open position and the fully closed position, while the tightening mechanism 1
5, when the door 10 is closed, the striker 71 (
(described later) is operated from the position where the door lock 12 contacts the latch 69 to the full lock position.

As shown in detail in FIGS. 2 and 3, the opening/closing mechanism 14 includes a push/pull member 18, a sector gear 19, a manual/automatic switching (planetary gear type) clutch mechanism 20, and an electric motor 21. Basically configured.

The push/pull member 18 has one end 18a connected to the vehicle body 11, and the other end 18b connected to the operating arm 19a of the sector gear 19.

The sector gear 19 is rotatably attached to a base board 24 fixed in the door 10 with a rotation shaft 25.

When the sector gear 19 is rotating clockwise (in the direction of the hour hand) as shown in FIG.
When the button rotates to the left (counterclockwise direction), the push/pull member 18 moves toward the door 1.
0 is pushed outside and the door 10 is opened.

The sector gear 19 is formed with an elongated hole 19b whose radius is the center of rotation (rotation axis 25) of the sector gear 19, and the inner and outer arc edges of the elongated hole 19b are provided with holes for half-opening and fully opening the door. Recessed portions 19c corresponding to each degree of opening.

19d is formed.

A blanket 26 facing into the elongated hole 19b of the sector gear 19 is fixed to the base substrate 24, and the blanket 26 is always in contact with the outer arc edge of the elongated hole 19b, and is attached to each recess 19c, 19d. rollers 27, 2 that can be engaged and detached from
A check spring 28.28 having a diameter of 7 is fixed.

Therefore, the check springs 28, 28 provide moderation for each opening degree when the sector gear 19 rotates, that is, when the door 10 is manually opened/closed.

A protrusion 19f is provided on the inner edge of the elongated hole 19b of the sector gear 19, and the protrusion 19f comes into contact with the base board 24 when the sector gear 19 is rotated to the right (fully closed position) and turned on. Fully closed detection switch 29 and sector gear 1
A fully open detection switch 30 is attached which is turned on when the protrusion 19f comes into contact with the protrusion 19f at the left rotation position (full open position).

A rotary encoder (door opening degree detector) 32 rotated by a gear 31 meshing with the sector gear 19 is attached to the base substrate 24, and the rotary encoder 32 detects the opening degree of the door IO.

In the planetary gear type clutch mechanism 20, a motor board 36 is fixed to the base board 24 via a plurality of supports 35, and the electric motor 21 is attached to the motor board 36 together with a speed reducer 37.

A small diameter output gear (sun gear) 40 is fixed to the output shaft 39 of the reduction gear 37.

A pin 4 is attached to the base board 24 coaxially with the output gear 40.
1 supports an intermediate gear 42, which meshes with the sector gear 19.

The intermediate gear 42 has three planetary gears 43 that mesh with the output gear 40. ..., 43 is pin 44. ...44
Each is supported by

A base portion 45a of an internal gear 45 is rotatably supported on the motor board 36 coaxially with the output gear 40, and the internal gear 45 meshes with each of the planetary gears 43. Saw teeth 45b are formed on the outer periphery of the internal gear teeth 45.

A solenoid 47 is fixed to the base board 24, and one end of a connecting lever 50 supported by a pin 49 on the base board 24 is connected to the plunger 48 of the solenoid 47. It is connected to a clutch member 51 that is reciprocatably supported by the base plate 24.

A sawtooth portion 51a that can mesh with the sawtooth 45b of the internal gear 45 is formed at the front portion of the clutch member 51.

When the solenoid 47 is energized, the clutch member 51 moves forward by retracting the plunger 48 and turning the connecting lever 50 to the right (around the hour hand), so that the sawtooth portion 51a meshes with the sawtooth 45b of the internal gear 45, and the inner While preventing the rotation of the gear 45, when the solenoid 47 is demagnetized, the plunger 48 is projected by the biasing force of the sprifug 52, and the linkage lever 50 is rotated counterclockwise (counterclockwise) to move backward.
The sawtooth portion 51a disengages from the sawtooth 45b of the internal gear 45, allowing the internal gear 45 to rotate.

Therefore, when the solenoid 47 is energized, the clutch member 51 meshes with the internal gear 45 and prevents the internal gear 45 from rotating. Therefore, when the electric motor 21 rotates forward or backward, the output gear 40 engages the internal gear 45 and prevents the internal gear 45 from rotating. The planetary gear 43 performs a planetary rotation movement between the intermediate gear 4 and the intermediate gear 4.
2 is rotated to rotate the sector gear 19 to the left or right.

Furthermore, when the solenoid 47 is demagnetized, the clutch member 51
does not mesh with the internal gear 45 and allows the internal gear 45 to rotate, so when the door 10 is manually opened and closed, the sector gear 1
9 rotates to the left or right, the intermediate gear 42 is rotated, and the planetary gear 43 rotates around the output gear 40 while rotating the internal gear 45. As a result, when the door 10 is manually opened/closed, the deceleration [37] and the electric motor 21 are not rotated, so that the opening/closing operation does not become heavy.

The planetary gear type clutch mechanism 20 has a simple structure and reliable operation, and is also easy to switch since it can be switched only by energizing and demagnetizing the solenoid 47.

In addition, an electromagnetic clutch is large in size in order to obtain torque, but Mizuna's planetary gear type clutch mechanism 20 can secure sufficient torque and can be made smaller.

A portion 69e of the latch 69 that the striker 71 first contacts (shown by hatching in FIG. 7) is electrically insulated from other portions, and together with the striker 71 constitutes a contact detection switch 116.

Therefore, when the door 10 is closed, the striker 7 on the vehicle body side
When the striker 1 contacts the portion 69e of the latch 69, the contact detection switch 116 is turned on, so that the position where the striker 71 contacts the latch is detected.

In addition, as a method for detecting the position where the striker 71 contacts the latch 69, there is also a method of attaching a vibration sensor to the striker 71 or the latch 69 and detecting the vibration at the time of contact, or a method of detecting the vibration at the time of contact with the striker 71 or the latch 69. There are other methods for detecting the contact position.

That is, when the close switch 124b is turned on in step S80, the solenoid 47 is turned on in step S81, and the motor 21 is turned on in step S82.

Next, in step S83, it is detected whether the close switch 124b is on or off, and if it is on, it is determined in step S84 whether or not an overload is acting, and if no, in step S85, the door lock 12 is turned off. It is detected whether the contact detection switch 116 is on or off, and if it is on, step S86
to operate the tightening mechanism 15.

Thereafter, the motor 21 is turned off in step 387, the solenoid 47 is turned off in step 588, the detection position of the rotary encoder 32 (door opening degree detector) of the opening/closing mechanism 14 is adjusted to the origin in step S89, and the detection position of the rotary encoder 32 (door opening degree detector) of the opening/closing mechanism 14 is adjusted to the origin, and in step S90 finish.

Further, when it is off in step S83, step S8
If the answer is YES in step S91, the motor 21 is turned off in step S91, the solenoid 47 is turned off in step S92, and the process ends in step S90.

(2) When the automatic opening door 10 is in the fully closed lock position and the fully open switch 123a of the manual switches 122 inside the vehicle is turned on, the solenoid 113 of the lock release mechanism 63 is energized, and the plunger 114 moves to protrude. Inner lever 88,
By swinging the open lever 79 via the bush lever 811 link 85, the locking of the latch 69 by the claw lever 72 is released.

As a result, the striker 71 is unlocked by the latch 69.

Furthermore, by energizing the solenoid 47 of the opening/closing mechanism 14, the clutch member 51 meshes with the internal gear 45 to prevent rotation of the internal gear 45, and at the same time, the electric motor 21
is reversed, the planetary gear 43 rotates planetarily between the output gear 40 and the internal gear 45, the intermediate gear 42 is rotated by the planetary gear 43, and the sector gear 19 is rotated to the left.

The push/pull member 18 moves toward the door 1 by counterclockwise rotation of the sector gear 19.
0, the door lO opens automatically,
When the fully open position is detected by the fully open detection switch 30, the electric motor 21 is stopped.

The one-touch opening routine of the automatic door opening described above is as shown in FIG.

That is, when the full open switch 123a is turned on in step S55, the unlock detection switch lot is turned on in step S56.
Detects whether it is on or off, and if it is off, the striker 71
Since the lock has not been released, the lock release mechanism 63 is activated in step S57.

If the unlock detection switch 101 is on, the solenoid 47 is turned on in step 558, and the motor 21 is turned on in step 559.

Next, it is determined in step 560 whether or not overload is acting, and if no, the current opening degree and the fully open degree are compared in step S61, and if they match (fully open), the process is performed in step S61.
The motor 21 is turned off in step S62, the solenoid 47 is turned off in step S63, and the process ends in step S64.

The lock release routine of the lock release mechanism 63 is the 17th
It will look like the figure.

That is, when the full open switch 123a is turned on in step S70, the solenoid 113 of the lock release mechanism 63 is turned on in step S71, and it is determined in step S72 whether or not an overload is acting on the lock release operation. If so, it is determined in step S73 whether or not the unlock detection switch 101 is turned on, and if YES, step S74
The solenoid 113 is turned on at step S75, and the process ends at step S75.

In addition, the one-touch selection routine for automatic door opening is the first one.
It will look like Figure 4.

That is, in step S40, the opening degree selection switch 123cm1 is
23i is turned on, the switch turned on is coded in step S41, and it is determined in step S42 whether or not there is one switch turned on. If YES, step S41 is turned on.
Step 43 detects the set opening degree, Step S44 detects the current opening degree, Step S45 calculates opening/closing data, Step S46 determines the opening/closing direction, and Step 348 turns the opening/closing mechanism 18 up to the set opening degree.・-The opening operation is performed, and the process ends in step S49.

Furthermore, the automatic door opening routine described above is as shown in FIG.

That is, when the open switch 124a is turned on in step S95, it is detected in step 396 whether the unlock detection switch +01 is on or off, and if it is off, the striker 71 is not unlocked, so the lock release mechanism is turned on in step S97. 63 is activated.

If the unlock detection switch 101 is on, the solenoid 47 is turned on in step 598, and the motor 21 is turned on in step S99.

Next, in step 3100, it is detected whether the door 10 is fully opened, and if no, it is determined in step 5101 whether an overload is being applied, and if no, step 5102
It is detected whether the open switch 124a is on or off, and if it is off, the motor 21 is turned off at step 5103, the solenoid 47 is turned off at step 5104, and the step 51 is turned off.
Ends with 05.

(3) When the manual closing door 10 is in the fully open position and the manual switch 122 inside the vehicle is not turned on, the solenoid 47 of the opening/closing mechanism 14 is demagnetized, so the clutch member 5
1 does not mesh with the internal gear 45, and rotation of the internal gear 45 is allowed.

Then, when the door 10 is manually closed, the push/pull member 18
is pushed into the door IO, the sector gear 19 is rotated clockwise, the intermediate gear 42 is accordingly rotated, and the planetary gear 43 rotates around the output gear 40 while rotating the internal gear 45.

During this manual door closing, the reducer 37 and electric motor 21 are not rotated from the sector gear 19 side, so the door closing operation can be easily performed.

Immediately before the door 10 is fully closed, after the striker 71 on the vehicle body comes into contact with the latch 69 of the door lock 12 in the unlocked position, the tightening mechanism 15 is operated in the same way as in (1) and the latch 6 is closed.
9 is forcibly rotated, and the door IO is fully closed and locked.

(4) Manual door opening When the inner handle or outer handle is pulled, the link 85 is moved down via the inner rod 91 or outer rod 92, and by swinging the open lever 79, the latch 6 is latched by the claw lever 72.
Release the lock of 9.

As a result, the striker 71 is unlocked by the latch 69.

Further, since the solenoid 47 of the opening/closing mechanism 14 is demagnetized, the clutch member 51 does not mesh with the internal gear, and rotation of the internal gear 45 is allowed.

Then, when the door 10 is manually opened, the push/pull member 18
is pulled out of the door 10, the sector gear 19 is rotated to the left, the intermediate gear 42 is accordingly rotated, and the planetary gear 43 rotates around the output gear 40 while rotating the internal gear 45.

Even when the door is opened manually, the speed reducer 37 and the electric motor 21 are not rotated from the sector gear 19 side, so the door opening operation can be easily performed.
