As mentioned above, conventional door check devices only provide resistance to the opening and closing of the door.
There are problems such as the door opening unexpectedly, damaging the door hinge and other parts, or the door closing unexpectedly, causing objects to become trapped between the vehicle body and the door.

Furthermore, when the vehicle is stopped on a slope such as a slope, if the door is left partially open, the door may open or close unexpectedly due to its own weight, causing the same problem as described above.

In particular, in order to improve aerodynamic performance, there is no handle for operating the door on the outside of the door.
In a conventional door lock that is automatically released by operating a switch or the like, a means is desired that can reliably prevent the door from being opened or closed unexpectedly due to wind or the like.

SUMMARY OF THE INVENTION An object of the present invention is to provide an automobile door lock device that can solve the above-mentioned problems and satisfy the above-mentioned demands.

The sector gear (64
) into which the push piece (64b) of the long hole (
68) and a pushing rod (69) with a hole therein.

The pushing rod (69) is connected to a pair of upper and lower suppressors (71) in a clamping device (70) provided on the front end wall of the door (2).
72) from above and below, it provides resistance to the movement of the push rod (69) into and out of the door (2) when the door (2) is opened and closed, and thereby the door (2) opens and closes. It also plays the role of a so-called check link, which provides a suitable amount of resistance.

(73) is a cover that covers the meshing part between the pinion (62) and the sector gear (64);
64).

When the sector gear (64) is in the non-operating position where it comes into contact with the stopper (66) and stops, the sector gear (64) operates by coming into contact with the front edge of the protrusion (64c) that is connected downwardly in the middle of the lower edge of the sector gear (64).

When the door (2) reaches the half-open position, the door (2) is restrained by the half-open locking device (D), but when this restraint is released and the door (2) is slightly opened from the half-open position, The door range detection switch (sw9) becomes inoperable.
This causes the motor to reverse.

The sector gear (64) is returned from the operating position to the inoperative position.

Therefore, while the door (2) is stopped at the half-open position, the sector gear (64) is stopped at the operating position, preventing the push rod (69) from entering the door, and preventing the half-opening lock from entering the door. Fi! This prevents the door (2) from closing unexpectedly to the fully open position at the same time as the door (D) is unlocked, thereby preventing the possibility of a hand being accidentally caught between the door (2) and the vehicle body (1). I'm starting to get it.

After the sector gear (64) returns to the inoperative position.

The operation at the time of closing of 2) is not directly related to the present invention.
A brief explanation is as follows. Manually move the door (2) from the half-open position to the half-latched position;
That is, when the latch (14) abuts the striker (13) and is rotated to the half-latched position, the door (2)
) When the locking rod (82) is closed to the half-open position, the slope (aZa) of the locking rod (82) comes into contact with the upper edge of the outer end of the engagement plate (87) and rides on it. is once lifted against the downward biasing force of the spring (87) and then engaged with the engagement hole (86).
a) slides along the inner upper edge of the engagement hole (86) and rides on the upper surface of the engagement plate (87) again. In the meantime, the door range detection switch (S119) is activated, but does not affect the operation of the motors (26), (61). When the door (2) and latch (14) reach the half-latched position, the half-latch detection switch (SV3) is activated, and the closure relay (111) activates the motor (
26) is energized as shown by the broken line in the figure, and the rotating plate (
29) is rotated clockwise in FIG. 1, and the closing device CB-2) is actuated. The operation of this closing device (B-2) forces the door (2) to close from the half-latched position to the fully open position. When the door (2) reaches the fully closed position and the latch (14) reaches the fully latched position, the full latch detection switch (511
4) is activated, the closure relay (111) is deenergized, and the latch release relay (110) is energized, causing current to flow through the motor (26) in the direction shown by the solid line in FIG. As a result, the rotating plate (29) is rotated back counterclockwise in FIG. 1, and when it reaches the neutral position, the neutral detection switch (SW6) is activated and the motor (26) is stopped. , the entire device returns to its original state when the door (2) is fully closed. Since other functions are not directly related to the present invention, detailed explanation thereof will be omitted. ” he corrected. (9) Page 28, line 17, before "Publicly known".
