DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door closer device which holds a door (ie, a side door, a trunk door, a hood door, etc.) of a vehicle in a completely closed state by moving a striker.

[0002]

2. Description of the Related Art For example, when a door of an automobile is closed, a large amount of force is required to close the door because a weatherstrip reaction force or a lock resistance acts immediately before the door is fully closed. Therefore, when the door is closed, the door often becomes a half-door state. In this case, the door must be closed again even if it is troublesome. In order to solve such a problem, there is known a door closer device in which the door is temporarily latched at a position that does not receive a weather strip reaction force, a lock resistance, or the like, and the door is moved to a completely closed position from that state. In such a door closer device, it is possible to eliminate the half-door, and also to improve the durability of the weather strip.

More specifically, in such a door closer device, as shown in FIG. 10, for example, a striker 52 erected on a vehicle body portion 51 is reciprocated vertically by, for example, an electric actuator (not shown). It is provided as possible. That is, when the door is opened, the striker 52 is at the solid line position in the drawing (hereinafter, referred to as an “initial position”), and the striker 52 and the latch mechanism 5 provided on the door side.
When the lock mechanism 3 is locked, the latch mechanism 53 is retracted to move to the position indicated by the two-dot chain line (hereinafter referred to as “retracted position”) in order to completely close the door.

FIGS. 11A and 11B show an existing technique for moving a striker between the above-mentioned "initial position" and "retracted position" by driving an electric motor.
In the figure, a worm gear 63 is connected to an output shaft 62 of an electric motor 61, and the worm gear 63 is meshed with a worm wheel 65 supported by a support shaft 64. A gear 66 provided coaxially with the worm wheel 65 is engaged with a gear 69 provided on the outer periphery of a rotating body 68 supported by a support shaft 67. Rotating body 68
, A rod-shaped striker 70 is erected near its outer peripheral position. Reference numeral 71 shown by a virtual line (two-dot chain line) in the figure is a well-known latch mechanism for locking to the striker 70.

Therefore, when the door is closed, the striker 70 is moved to the position indicated by the solid line in FIG.
, The drive motor 61 is started, whereby the worm gear 63, the worm wheel 65, the gear 6
The rotating body 68 rotates via the gear 6 and the gear portion 69. Then, the striker 70 provided on the rotating body 68 moves along a circular orbit, and reaches the position indicated by the two-dot chain line (retraction position) in the figure. The latch mechanism 71 is retracted with the circular movement of the striker 70 driven by the electric drive, and the door is kept in a completely closed state.

[0006]

However, FIG.
According to the prior art, when the striker 70 is moved from the “initial position” to the “retracted position”, the latch mechanism 71 (and the door itself) is moved in the horizontal direction in FIG. The swinging direction is different from the direction, that is, the direction in which the door is closed (directly below the drawing), so that an extra force acts to cause a disadvantage in strength. On the other hand, to allow such lateral movement,
It is necessary to allow the latch mechanism 71 (and the door itself) to have a loose margin, which has also been a negative factor in the configuration. In addition, there is a disadvantage that the stroke amount when the striker 70 is retracted is naturally limited.

Although illustration is omitted, as another conventional example, a worm shaft is driven by a driving motor, a worm wheel fitted to the worm shaft is rotated, and a screw shaft fitted to the worm wheel is moved up and down. A door closer device has been proposed in which the striker is moved from the latch position to the fully closed position by slidably driving the device. However, in such a device, the structure required for moving the striker becomes large, and the cost is increased. Is generated.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has as its object to reduce the cost and appropriately perform the closing operation of the door without applying an extra force. The object of the present invention is to provide a door closer device that can be operated.

[0009]

In order to achieve the above object, the present invention according to claim 1 has a striker for engaging with a latch mechanism, and the striker is engaged with the latch mechanism. In the door closer device which holds the door in the closed state by moving the striker, the end of the striker is supported by the main body at two positions, and the portion extending from the two positions is a locking portion with the latch mechanism. The gist is that one part is disposed so as to be capable of linear movement, and the other non-locking part is disposed so as to be movable in a direction different from the linear movement direction of the locking part.

According to a second aspect of the present invention, in the first aspect of the present invention, the non-locking portion of the striker is disposed so as to be rotatable. According to a third aspect of the present invention, in the second aspect of the present invention, the locking portion of the striker is connected to a linearly formed guide portion, and the non-locking portion is connected to an output shaft driven by a driving source. Connected to a crank rotating part that rotates eccentrically.

According to a fourth aspect of the present invention, in the third aspect of the invention, a rotating body is attached to an output shaft of the drive source, and a non-locking portion of the striker is provided at an eccentric position of the rotating body. Attachment thereby constitutes the crank rotating part.

(Operation) According to the first aspect of the present invention,
Under the locked state of the striker and the latch mechanism, the locked portion of the striker moves linearly, that is, in the same direction as the direction of retraction of the door, and thereby the door is held in the closed state. At this time, in order to assist the linear movement of the locking part, the non-locking part of the striker moves in a direction different from the linear movement direction of the locking part. In this case, unlike the related art described above, there is no inconvenience that the latch mechanism and the door swing right and left and right in a circular orbit. Also, there is no need for an unnecessarily large drive mechanism or the like. As a result, the cost can be reduced, and the closing operation of the door can be properly performed without applying an extra force.

According to the second aspect of the present invention, when the non-locking portion of the striker rotates, the locking portion of the striker moves linearly. Also in this case, the door closing operation is performed while suppressing the application of an excessive force in the lateral direction or the like to the locking portion of the striker. In particular, in the present configuration, the configuration relating to the operation of the striker can be further reduced in size. The non-locking part of the striker
It moves along a circular orbit as in the conventional configuration, but since no force is exerted by the latch, there is no problem in strength at such a portion.

According to the third aspect of the present invention, the non-locking portion of the striker rotates by the operation of the crank rotating portion which is eccentrically rotated with respect to the output shaft by the driving source. Then, with the rotation, the locking portion of the striker moves linearly along the linear guide portion.

According to the fourth aspect of the present invention, the non-locking portion of the striker attached to the eccentric position of the rotating body rotates with the rotation of the rotating body by the output shaft of the driving source. Thereby, a linear motion of the locking portion of the striker is obtained.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of a door closer device according to the present invention will be described below with reference to the drawings.
The door closer device according to the present embodiment is provided in a rear trunk portion of an automobile, and is mainly provided at a position opposed to the striker and a driving mechanism for the striker disposed on the vehicle side and the trunk door side. And a latch mechanism. In brief, in this apparatus, when the trunk door is closed and the striker and the latch mechanism are locked, the electric motor is driven to forcibly retract the striker and completely close and close the trunk door. I keep it in a state. In this door closer device, opening and closing control by operating an opener provided inside and outside the trunk door is also performed by electronic control.

FIGS. 1 to 5 show the construction of the door closer device in detail. FIGS. 1 to 3 show the construction of the striker 1 on the vehicle body side and its driving mechanism, and FIGS. 4 and 5 show the trunk door. 2 shows the configuration of the side latch mechanism 16. First, the striker 1 and its driving mechanism will be described with reference to FIGS. 1 (a) and 1 (b)
FIG. 2 is a front view and a longitudinal sectional view of the mechanism, and FIG.
3 is a sectional view taken along line III-III in FIG.

As shown in these figures, the striker 1 is bent as shown. Upper and lower 2 of striker 1
The two base ends 2a and 2b are arranged on a case main body 3 as a substantially flat main body, and the striker 1 stands upright with respect to the plane direction of the case main body 3. In this striker 1, the straight portion 1a extending from the upper base portion 2a in FIG. 1 constitutes a locking portion to be locked with a latch mechanism 16 described later, and the bent portion 1 extending from the lower base portion 2b in the drawing.
b constitutes a non-locking portion that does not lock with the latch mechanism 16.

The case body 3 has an upper plate 4 and a lower plate 5 stacked on each other, and is fixed to a vehicle trunk (not shown) by bolts 6. At a substantially central portion of the case body 3, a part of the upper plate 4 is formed in a convex shape, thereby forming a space 7 between the upper plate 4 and the lower plate 5.
In the space 7, both base ends 2a, 2b of the striker 1 are provided.
In addition, a long plate 8 connecting them is provided. Further, both base ends 2a and 2b of the striker 1 are movably supported by thrust washers 9, respectively.

A long hole 10 is formed in the upper plate 4 of the case body 3 as a guide extending in the vertical direction in FIG.
As shown in FIG. 1 (a), substantially the entirety of the long hole 10 extends along the longitudinal direction of the striker 1, and has a circular hole 11 at the lower part of the figure. In such a case, the upper base end 2a of the striker 1 is accommodated so as to be able to reciprocate linearly in the vertical direction in the figure along the elongated hole 10.

A lower base 2b of the striker 1 is accommodated in a circular hole 11, and a pin 12 provided in the base 2b is connected to a rotating body 13 on the back side of the case body 3. Since the pin 12 coaxial with the base end 2b is connected to a position slightly shifted from the rotation shaft 14 located at the center of the rotating body 13, the base end 2b, that is, the bent portion 1b of the striker 1 rotates. It can be eccentrically rotated with respect to the body 13.

The rotating body 13 is provided in the motor driving section 15, and has gear teeth 13a formed on the outer peripheral surface thereof. The motor drive unit 15 mainly includes a plurality of reduction gears (not shown) and an electric motor as a drive source. In the present embodiment, the rotating shaft 14 of the rotating body 13 corresponds to an output shaft of a driving source. Further, the configuration of the rotating body 13 and the rotating shaft 14 in the motor drive unit 15 and the lower end base 2b of the striker 1 corresponds to a crank rotating unit described in the claims. In general, a motor driven at a high speed is smaller in size. Therefore, in the present embodiment, a small motor driven at a high speed is used, and a reduction gear is built in so as to obtain an output of a required rotational speed. Is composed.

In the above configuration, when the electric motor (not shown) in the motor drive unit 15 is driven and the rotating body 13 rotates by 180 °, the lower proximal end 2 of the striker 1 is rotated.
b and the bent portion 1b extending therefrom rotate by the amount of a semicircle, and accordingly, the upper base end portion 2a of the striker 1 and the linear portion 1a extending therefrom move downward in the drawing. That is, the striker 1 moves from the position indicated by the solid line to the position indicated by the two-dot chain line in FIG. At this time, the solid line position of the striker 1 corresponds to an “initial position” that is a state before the striker 1 and a latch mechanism 16 to be described later are locked and a state immediately after the lock, and The position indicated by the dashed line corresponds to a “retracted position” in which the latch mechanism 16 is retracted to completely close the trunk door.

The "initial position" of the striker 1 means that when the door is closed, there is no reaction force or lock resistance of a weatherstrip provided around the trunk opening, and the weatherstrip is required. The position is provided in consideration of, for example, not pressing.

A trunk door is closed on the main body case 3 so that the striker 1 and a latch mechanism 1 to be described later are closed.
6 which detects that the lock switch 6 has been locked.
W1 is provided. That is, the first switch SW
Reference numeral 1 denotes that when the trunk door is closed, the distal end portion 31 is pressed by a pressing member (not shown), and accordingly, an electric path described later is switched.

Next, the configuration of the latch mechanism 16 provided on the trunk door D side will be described with reference to FIGS. FIG. 4 shows a state before locking of the striker 1 and the latch mechanism 16, and FIG. 5 shows a state after locking of both.

As shown in each figure, an insertion passage 18 into which the striker 1 is inserted is formed in a substrate 17 of the latch mechanism 16, and a latch 19 is disposed in the vicinity thereof so as to be rotatable around a support shaft 20. Has been established. One end of a tension coil spring 21 is attached to a part of the latch 19, and the latch 19 is urged clockwise in FIG. At the outer peripheral edge of the latch 19, there are a claw portion 19 a that guides the striker 1 through and locks the striker 1, and a locking portion 19 b that locks with the ratchet 22 disposed opposite to the latch 19. Are formed. The position of the latch 19 is regulated by a stopper (not shown) in the biasing direction (clockwise direction in the figure).

The other end of the tension coil spring 21 is connected to a ratchet 22. Ratchet 22
Is provided so as to be rotatable about a support shaft 23, and is urged by the tension coil spring 21 in a counterclockwise direction in the drawing, that is, a direction in which it comes into contact with the outer peripheral surface of the latch 19. The surface of the ratchet 22 that comes into contact with the outer peripheral surface (locking portion 19b) of the latch 19 is formed as a curved surface 22a, and a latch surface 22b is formed at the upper end of the curved surface 22a.

Therefore, when the trunk door D is closed and the striker 1 is inserted into the insertion passage 18, the striker 1 (the linear portion 1a in FIG. 1) pushes the latch 19, whereby the latch 19 is pulled by the tension coil spring 21. Rotates counterclockwise in the figure against the urging force of. At this time, when the locking portion 19b of the latch 19 moves along the curved surface 22a of the ratchet 22, and reaches the upper end of the curved surface 22a, the locking portion 19b of the latch 19 and the latch surface 22b of the ratchet 22 Will be locked.

Thus, as shown in FIG. 5, the striker 1 (the linear portion 1a thereof) and the latch 19 (the claw portion 19 thereof)
a) is held in the locked state, and the trunk door D is closed. Incidentally, in order to release the locked state between the striker 1 and the latch 19, the release lever 24 provided at the upper end of the ratchet 22 is pulled rightward in the drawing, and
The latching state between the latching portion 19b and the latch surface 22b of the ratchet 22 may be released. The release lever 24 is operated, for example, by operating an opener provided in the vehicle interior.
Alternatively, it is activated by a key operation outside the trunk.

On the other hand, on the outer peripheral surface of the rotating body 13 shown in FIG. 1 (the portion other than the gear teeth 13a), as shown in FIG. 6, a convex detection portion 25 is provided. In addition, at the 180 ° opposing position with the rotating body 13 interposed therebetween, a second contactable part that can contact the detection target 25 as the rotating body 13 rotates.
A switch SW2 and a third switch SW3 are provided. Here, the striker 1 is the “initial position” (see FIG. 1).
6, the detected part 25 and the detection part 33 of the third switch SW3 come into contact with each other, as shown in FIG. Further, when the rotating body 13 is rotated by 180 ° from the illustrated state and the striker 1 is in the “retracted position” (see FIG. 1), instead of the contact between the detected part 25 and the detection part 33 of the third switch SW3, , The detected part 25 and the detecting part 32 of the second switch SW2 come into contact with each other.

The second and third switches SW2 and SW3
In addition, the first switch SW1 shown in FIG. 1 has a circuit configuration as shown in FIG. That is, FIG. 7 shows a control circuit for controlling the driving of the electric motor M, and the states of the switches SW1 to SW3 in the figure correspond to the open state of the trunk door D. In this control circuit, the battery power supply + B is connected to the “c terminal” of the first switch SW1, and the “a contact” and “b contact” of the switch SW1 are connected to the second switch SW2 and the third switch SW3, respectively. ing. The second switch SW2 and the third switch SW3 which are in parallel with each other include:
The plus terminal of the electric motor M is connected.

The state shown in the figure shows the state in which the striker 1 is at the "initial position", and the first switch S
The “c terminal” of W1 is connected to the “a contact”. In this state, the rotating body 13 is in the state shown in FIG.
As shown in the drawing, when the detection section 32 of the second switch SW2 and the detection section 25 of the rotating body 13 are in a non-contact state, the second switch SW2 is configured to be “ON”. Further, as shown in the figure, the third switch SW3
The third switch SW3 is set to "OFF" when the detecting unit 33 of the rotating body 13 and the detected unit 25 of the rotating body 13 are in contact with each other.

Next, the operation of the door closer device configured as described above will be described with reference to the aforementioned configuration diagrams of FIGS. 1 to 7 and a time chart of FIG. 8, when the trunk door D is opened (before time t1 in FIG. 8), the first to third switches SW1 to SW
7 is in the initial state in FIG. 7, and the striker 1 is held at the “initial position” in FIG. At this time, no voltage is applied to the electric motor M, and the motor voltage is maintained at “0 volt”.

When the trunk door D is manually closed at time t1, the striker 1 and the latch mechanism 16 are locked. At this time, the door itself is held at a position where the door slightly touches the weather strip disposed in the trunk opening, and the door is in a “half-open state”. Also, at this time t1, the first switch SW1 is pressed by a pressing member (not shown), and the connection of the switch SW1 is switched from "ac connection" to "bc connection". With this switching operation, a drive voltage is applied to the electric motor M.

Thus, the lower base 2 of the striker 1
b starts a rotational movement in accordance with the rotation of the rotating body 13, and accordingly, the linear portion 1a, which is the locking portion of the striker 1, moves downward from the state of FIG. At this time, the state of the second switch SW2 does not change, that is, is maintained in the “ON” state, whereas immediately after the time t1, the detection unit 33 of the third switch SW3 and the rotation of the rotating body 13 are closed. Since the detection unit 25 is separated, the third switch SW3 is set to “O
FF ”is switched to“ ON ”.

The period from time t1 to time t2 corresponds to a period in which the linear portion (locking portion) 1a of the striker 1 moves from the "initial position" to the "retracted position" in FIG. Is pulled from the "half-open state" to the "fully-closed state". Then, at time t2, the striker 1 stops at the "retracted position", and the trunk door D is completely closed. At this time t2, the second switch SW2
Switch SW2 is switched from “ON” to “OFF” (the third switch SW3 is “OFF”).
Will be kept as is). Therefore, the voltage application to the electric motor M is stopped.

Thereafter, when the trunk door D is opened, the following operation is performed. That is, when, for example, the opener in the vehicle compartment is operated at the time t3, the locked state between the striker 1 and the latch mechanism 16 is released by the release lever 24 of the latch mechanism 16 accordingly. At this time, since the trunk door D is lifted, the pressing of the first switch SW1 is released, and the connection of the switch SW1 is switched from the "connection between bc" to the "connection between ac". During this switching operation, the third switch SW
Since “3” is “ON”, a driving voltage is applied to the electric motor M accordingly.

Thus, the lower base 2 of the striker 1
b resumes the rotational movement according to the rotation of the rotating body 13, and the linear portion (locking portion) 1a of the striker 1 moves upward. At this time, the state of the third switch SW3 does not change,
That is, while being kept in the “ON” state, immediately after the time t3, the detection unit 32 of the second switch SW2
The second switch SW <b> 2 is switched from “OFF” to “ON” since the detection unit 25 is separated from the detection unit 25 of the rotating body 13.

The period from time t3 to t4 corresponds to a period in which the linear portion (locking portion) 1a of the striker 1 moves from the "retracted position" to the "initial position" in FIG.
The striker 1 stops at the “initial position”. Also, at this time t4, the detection unit 33 of the third switch SW3 and the rotating body 1
3 comes into contact with the detection target 25 of the switch SW3.
Is switched from “ON” to “OFF”. Therefore, the voltage application to the electric motor M is stopped.

(A) In the present embodiment, the linear portion (locking portion) 1a of the striker 1 linearly moves by rotating the bent portion (non-locking portion) 1b of the striker 1. In this case, unlike the related art, there is no inconvenience that the latch mechanism 16 and the door swing in the left and right lateral directions (directions different from the closing direction of the door) in a circular orbit. Also, there is no need for an unnecessarily large drive mechanism or the like. As a result, the cost can be reduced, and the closing operation of the door can be properly performed without applying an extra force.

(B) In the above configuration, the striker 1

Although the locking portion (linear portion 1a) of the striker 1 is linearly moved, this configuration may be changed. For example, the non-locking portion of the striker 1 may be rotated by 90 ° to thereby obtain a linear motion of the locking portion (however, the rotation angle of the non-locking portion may be arbitrary). In this case, it is necessary to slightly increase the diameter of the rotating body, but a desired effect can be obtained with such a configuration.

As shown in FIG. 9, in a case body 41 as a main body, an engaging portion 42 of a striker 42 is provided.
a is provided with a guide portion 43 (for example, a long hole) for linearly moving the a in the vertical direction (door closing direction) of the drawing, and the non-locking portion 42b of the striker 42 is linearly moved in the horizontal direction of the drawing. A guide 44 (for example, a long hole) for exercise is provided. The non-locking portion 42b of the striker 42
Is connected to a slide actuator 46 by a link 45. In this case, by driving the slide actuator 46 to reciprocate the non-locking portion 42b of the striker 42 in the horizontal direction in the drawing, the locking portion 42a of the striker 42 linearly moves in the vertical direction in the drawing. become. Therefore, the object of the present invention, such as performing the closing operation of the door without applying extra force, is achieved. In short, if the non-locking portion of the striker is arranged so as to be movable in a direction different from the direction of linear movement of the locking portion, the object of the present invention can be achieved, and the configuration can be arbitrarily changed within the range. it can.

(2) In the above embodiment, the output of the electric motor is transmitted to the rotating body via the reduction gear or the like using the motor drive unit 15 having the reduction gear. A configuration in which a rotating body is directly connected to the output shaft may be adopted. If a low-speed electric motor is used, a desired operation speed can be secured.

(3) The rotating body is not limited to a disk-shaped one, but any structure that can take out a circular motion in one direction is sufficient.
For example, a rod-shaped member such as a crank connected to the output shaft may be used.

(4) The shape of the striker is not limited to the illustrated one. In short, the end is 2
Any position may be used as long as one part of the two positions is a locking part and the other part is a non-locking part.

(5) In the above embodiment, the door closer device of the present invention is applied to a trunk portion of an automobile. However, the present invention can be applied to, for example, a side door, a back door, a sunroof, and the like. In short, the present invention can be applied to all doors (doors) that require locking and unlocking in an automobile.
