Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle door closer device for closing a vehicle door so that the vehicle door is fully latched (fully closed) when the vehicle door is in a half-latch state, that is, in a so-called half-door state.

[0002]

2. Description of the Related Art A vehicle door closer device includes, for example,
When it is determined that the vehicle is in the half-door state by means for detecting the closed state of the vehicle door, such as a switch means provided on the vehicle body or the vehicle door, the vehicle door is moved using the driving force of a motor or the like to complete the operation. It is to be closed. In general, a vehicle door is closed by a door holding striker fixed to one of the vehicle body and the vehicle door and a door holding latch fixed to the other side and engaged with the door holding striker. ing. Conventionally, in a vehicle door closer device, a driving force of a motor is applied to a door holding striker via a door holding latch for drawing in, so that the vehicle door is drawn into the vehicle interior.

[0003]

By the way, the inventors assumed that a vehicle door has a larger window area in order to improve the visibility of the vehicle door, and prototyped the vehicle door closer device. In an effort to make various studies, the following conclusions were reached.

That is, in order to improve the visibility, it is more effective to enlarge the window area in the front-rear direction than in the vertical direction of the vehicle door in order to improve the visibility.
As a result, it is more effective to reduce the thickness of the vehicle door closer device installed at the rear end of the vehicle in the front-rear direction of the vehicle door because the vertical movement of the window is not restricted.

Therefore, in the above-described vehicle door closer device, the components of the vehicle door closer device such as the motor, the speed reducer, the retracting latch and the limit switch are inevitably concentrated near the holding striker. In addition to the components, mechanisms that maintain the original closed state of the vehicle door, such as existing holding latches and locking mechanisms, are also concentrated near the holding striker, causing interference problems between the components. In order to avoid interference, there is a problem that the structure is inevitably increased in size. That is, this is disadvantageous in increasing the area of the window in the front-rear direction of the vehicle.

Accordingly, the present invention has been made in view of the above points, and
In particular, it is an object of the present invention to provide a vehicle door closer device that is made thinner in the front-rear direction of the vehicle.

[0007]

The present invention uses the following technical means to achieve the above object. According to the first aspect of the present invention, the door holding latch of the door holding mechanism, the door closer latch of the door closer mechanism, and the interlocking member of the door opening / closing detecting means are arranged vertically when the vehicle door is in the full latch state. It is characterized by the following. As a result, the vehicle door closer can be made thinner in the front-rear direction of the vehicle door.

[0008] The invention described in claim 2 is characterized in that the door holding latch, the door closer latch, and the interlocking member are constituted by a rotating body. This simplifies the structure as compared to one that operates with linear motion.

Numeral 2e is provided to regulate the rotation range of the detection plate 72a, and is designed so that the initial position of the detection plate 72a is fixed so as not to exceed the elastic limit of the return spring 72b.

Next, the initial position detecting means 73 will be described. The initial position detecting means 73 detects the initial position of the door closer latch 71b.
It is fixed to the housing 70 with screws or the like.

Next, the closing operation of the door closer device 3 will be described with reference to FIGS. 1 and 5 to 9. FIG. 5 is a schematic diagram of a control system for explaining the operation of the door closer device 3,
6 to 9 are schematic diagrams for explaining the movement of the door closer device 3. FIG. When the vehicle door 2 is closed in the closing direction from the initial state of the door closer latch 71b and the detection plate 72a in FIG. 6, the door holding mechanism 4 and the door holding mechanism 6 with the door closer striker 5 fastened to the vehicle body 1 are fixed to the door. Storage groove 60 of door closer mechanism 7
a and 70a begin to be stored simultaneously. When the closing operation is further continued, the door holding striker 4 becomes a half latch by the door holding mechanism 6. At the same time, the door closer striker 5 also rotates the detection plate 72a counterclockwise against the pressing force of the return spring 72b. With the door holding striker 4 in the half-latch state, the first limit switch 72c turns the detection plate 72a
Is turned on by the outer peripheral surface on the circular arc.

Then, as shown in FIG. 5, the signal of the first limit switch 72c is inputted to the ECU 74 as the control means, and the electric motor as the drive means, the plurality of gears and the shaft 71 are provided.
The door closer latch 71b starts to rotate clockwise through a.

When the door closer latch 71b continues to rotate, it comes into contact with the door closer striker 5 as shown in FIG. 7, and thereafter, the door closer striker 5 and the detection plate 72a are kept pressed, and the vehicle door 2 starts closing. At this time, the door holding striker 4 also continues to be pushed to the full latch position of the door holding mechanism 6, and eventually the door holding striker 4 reaches the full latch position, and the vehicle door 2 is held by the door holding mechanism 6. . At the same time, since the detection plate 72a is also continuing to rotate, when the door holding striker 4 reaches the full latch position, the second limit switch 72d then moves the outer periphery of the detection plate 72a on the arc as shown in FIG. It is turned on by the surface.

Then, as shown in FIG. 5, the signal of the second limit switch 72d is input to the ECU 74 as the control means, and the door latch 71b stops its rotation and rotates counterclockwise.

Then, the door closer latch 71b continues to rotate in reverse, and the third limit switch 73a is turned on this time by the outer peripheral surface on the arc. Then, the door latch 71b
Is determined to be the initial position, and as shown in FIG.
The ECU 74 causes the door latch 71b to stop rotating.
At this time, since the door 2 is held by the door holding mechanism 6, the door closer mechanism 7 does not move, and the door 2 maintains the full latch (completely closed) state.

Next, the opening operation of the door closer device 3 will be described. When the door holding mechanism 6 is released from the state shown in FIG. 9, the door closer mechanism 7 moves rightward in the drawing due to the reaction force of the weather strip 21 (see FIG. 1) mounted on the door. At this time, since the door closer latch 71b has returned to the initial position, it does not hinder its movement. Also, the detection plate 72a is rotated clockwise by the return spring 72b, and stops rotating by fitting the pin 70f and the elongated hole 72e in the initial position.
Thus, the door closer latch 71b and the detection plate 7
Both 2a return to the initial position, become the state of FIG. 6, and prepare for the next closing operation.

As described above, this embodiment has the following features.
