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 completely closed when the vehicle door is in a poor closed state, that is, in a so-called half-door state.

[0002]

2. Description of the Related Art A vehicle door closer device is, for example,
When it is determined that the vehicle is in a half-door state by means of a switch body or other means for detecting the closed state of the vehicle door provided on the vehicle door, the driving force of a motor or the like is used to move the vehicle door to complete It is a closed state.

Generally, a vehicle door is kept in a closed state by a holding striker fixed to one side of the vehicle body and the vehicle door and a holding latch fixed to the other side and engaged with the holding striker. Has been done.
In the conventional vehicle door closer device, a driving force of a motor is applied to the holding striker via a retracting latch to retract the vehicle door into the passenger compartment.

[0004]

For this reason, 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. Moreover, in addition to these components, existing holding latches, locking mechanisms, and other mechanisms that hold the original closed state of the vehicle door are also concentrated in the vicinity of the holding striker. Occurs,
There is a problem that the structure of each component becomes complicated in order to avoid interference.

In view of the above points, an object of the present invention is to provide a vehicle door closer device having a simple structure near the holding striker.

[0006]

The present invention uses the following technical means in order to achieve the above object. Claim 1
In the invention described in 6, the vehicle main body and the vehicle door (2) are independent of the holding striker (5) when the closed state of the vehicle door (2) is determined to be poor by the door closed state detection means (11). It is characterized in that the vehicle door (2) is closed by applying a door operating force to the door closer striker (10) fixed to one of the two sides.

Thus, the existing holding striker (5)
It is possible to prevent the door closed state detecting means (11) and the door closer mechanism (12) from being concentrated in the vicinity of. Therefore, since the vicinity of the holding striker (5) can have a simple structure, it is possible to avoid the occurrence of the interference problem of each component. As a result, it is possible to suppress an increase in the manufacturing cost of the door closer device 1.

The coil spring 115 is formed on the inner wall of the elongated hole 111c formed on the switch cam 111 and on the bracket 125. It is arranged between the columnar protrusion 125a. Next, the operation of the door closer device 1 according to the present embodiment will be described by focusing on the operation of the switch cam 111 and the door closer latch 123 in the following three cases.

1. When in the half-door state (see FIGS. 6 and 7) When the door 2 is open, the half-latch switch 113
As shown in FIG. 6 (A), the tip end of the switch lever 113a of the switch contacts the surface 111d formed on the switch cam 111 and extending outward in the radial direction. Is in the OFF state (hereinafter,
Called the initial state of the cam. ).

Further, when the door 2 is open, the latch contact surface 123a of the door closer latch 123 and the door closer striker 10 are not in contact with each other (hereinafter referred to as the latch initial state), and the switch lever of the home position switch 124. The tip of 124a is a door closer latch 1
The home position switch 124 is in the ON state by contacting the latch cam surface 123b of 23.

When the door 2 is further closed and the door closer striker 10 comes into contact with the contact surface 111e of the switch cam 111, the cam switch 111 is turned (in the counterclockwise direction on the paper surface) as shown in FIG. 6B. It rotates, the tip of the switch lever 113a contacts the cam surface 111a, the half latch switch 113 is turned on, and the signal 113b is input to the control device 13.

As a result, as shown in FIG. 6C,
As the motor 121 rotates, the latch contact surface 123
The door a is brought into contact with the door closer striker 10 to generate a door operation force, and the door 2 is pulled into the vehicle interior side to close the door 2. At this time, the tip of the switch lever 124a of the home position switch 124 is not in contact with the latch cam surface 123b of the door closer latch 123, and the home position switch 124 is in the OFF state.

When the door 2 is moved and the switch cam 111 is further rotated to bring the door 2 into a fully closed state (full latch state), the tip of the switch lever 112a of the full latch switch 112 comes into contact with the cam surface 111b. The full latch switch 112 is turned on. And
When the signal 112b is issued from the full-latch switch 112, the door closer latch 123 is operated until the tip of the switch lever 124a of the home position switch 124 contacts the latch cam surface 123b of the door closer latch 123, that is, the home position switch 124 is turned off.
Reverse rotation is performed until the N state is reached and the latch initial state is restored (position (D) in FIG. 6).

When the door 2 is opened, the switch cam 11
1 is returned to the initial cam state by the coil spring 115. Further, FIG. 7 shows each switch 11 in the above operation.
It is a time chart of 2,113,124. 2. When the door 2 is normally closed and is in the completely closed state (full latched state) The operation of the switch cam 100 in this case is the same as the operation in the half-door state, but the door 2 is normally closed. When the door 2 is closed completely, the door 2 normally has momentum, so that the half-latch switch 113 and the full-latch switch 112 are turned on almost at the same time, and the home position switch 124 is turned off. Almost never. Therefore, the door closer latch 12
3 hardly moves. Also, temporarily, the door closer latch 12
Even if 3 moves to pull in the door 2, the door closer latch 123 returns to the latch initial state because the signal 112b is issued from the full latch switch 112.

Next, the features of this embodiment will be described. In the present embodiment, since the door closer striker 10 is provided independently of the existing holding striker 5, the configuration of the door closer device 1 such as the door closed state detection unit 11 and the door closer mechanism 12 is provided in the vicinity of the existing holding striker 5. It is possible to avoid device concentration. Therefore, the occurrence of the interference problem of each component is suppressed, and the vicinity of the holding striker 5 can have a simple structure. As a result, it is possible to suppress an increase in the manufacturing cost of the door closer device 1.

Further, in this embodiment, since the closed state of the door 2 is determined by the ON-OFF state of the full-latch switch 112, compared with the case where the motor is stopped after detecting the overload current of the motor. , The door closer latch 123 is quickly inverted. Therefore, the door 2 can be opened even immediately after the door closer device 1 is completely closed.

(Second Embodiment) In the present embodiment, when the door closer device 1 pulls the door 2 into the vehicle interior, a foreign matter such as a finger is prevented from being caught between the door 2 and the vehicle body. It has a mechanism added. That is, the door closed state detection unit 11 is provided with a limit switch (hereinafter, referred to as a pinch prevention switch) 126 as a pinch detection means for detecting the pinch. As shown in FIG. 9, the entrapment prevention switch 126 overlaps the full-latch switch 112 in the direction perpendicular to the paper surface, and the front side of the paper surface is the entrapment prevention switch 126 and the back side of the paper surface is the full-latch switch 112.

The trapping prevention switch 126
Is the switch lever 12 of the pinch prevention switch 126.
The tip of 6a comes into contact with the convex portion 123d formed on the door closer latch 123 to be turned on, and the signal 126 from the pinch prevention switch 126 is output.
b is input to the control device 13 (see FIG. 5). Further, in the present embodiment, the entrapment prevention switch 126 and the full-latch switch 112 overlap each other in the direction perpendicular to the paper surface, but the positional relationship between both switches 126 and 112 is not limited to this, and both switches 126 and 112 are not limited to this. This embodiment can be carried out even if is shifted about the axis 122e.

Next, the operation of this embodiment will be described. Door 2
When the door closes, the switch cam 111 and the door closer latch 123 operate in the same manner as in the above-described embodiment, and when the door closer latch 123 rotates to a predetermined position, the switch lever 1 of the pinch prevention switch 126 is released.
The tip of 26a is the convex portion 12 of the door closer latch 123.
The pinch prevention switch 126 is turned on by contacting the 3d (see FIG. 9A).

The entrapment prevention switch 126 is turned off.
When a foreign object such as a finger is caught between the door 2 and the vehicle body in the N state, the current value supplied to the motor 121 is such that the foreign object is not caught as shown by the chain double-dashed line in FIG. The current value reaches the predetermined current value earlier than the normal time. Therefore, the trapping prevention switch 126 is turned on.
A predetermined time (1 sec in this embodiment)
When the current value supplied to the motor 121 in c) reaches a predetermined value (set current value), it is considered that a foreign object is trapped and the motor 121 is rotated in the reverse direction (see (B) of FIG. 9). Note that FIG. 11 shows the switches 112 and 11 in the above operation.
It is a time chart of 3,124,126.

As described above, in the present embodiment, since the entrapment is detected by the two parameters, that is, the signal 126b from the entrapment prevention switch 126 and the current value supplied to the motor 121, the entrapment is surely performed. Can be detected. Further, since the pinch prevention mechanism can be easily configured by adding one limit switch to the above-described embodiment, it is possible to suppress an increase in manufacturing cost of the door closer device 1.

In this embodiment, the tip of the switch lever 126a of the pinch prevention switch 126 comes into contact with the holding striker 5, so that the pinch prevention switch 1
The pinch prevention switch 126 may be arranged at a portion of the door 2 where the switch 26 is turned on. By the way, in the above-described embodiment, the switches 112 and 113 are operated by the switch cam 111, but as shown in FIG.
The switch levers 112a and 113a of 2, 113 may be brought into direct contact with the door closer striker 10 to operate each switch.

Further, in the above-mentioned embodiment, the limit switch is used as each switch means, but as shown in FIG. 13, the magnet 200 is arranged on the door closer striker 10 and the magnetic flux is generated by the movement of the magnet 200.
