Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a child lock mechanism provided on an automobile door.

1. Prior Art 1. As is well known, in a rear seat automobile door as shown in FIG. A locking mechanism may be provided. That is, this child lock mechanism disables the operation of the inside handle 4 and releases the door lock l by only operating the outside handle 5 outside the vehicle, regardless of the locking or unlocking operation position of the inside lock knob 3. As shown in Figure 5, the lever 2 for operating the child lock mechanism is exposed from the wall surface of the door inner panel 6 which is hidden by the rear seat when the rear car door is closed (for example,
(Refer to No. 7174), therefore, with such a car door, when an infant etc. gets into the rear seat, if the child lock lever 2 is manually operated to the open position, the door inside the car can be secured. However, with this structure, it is difficult to visually confirm the operation position of the child lock lever 2 when the door is closed, so the child lock mechanism can be prevented from locking while driving. In addition, the door lock lever 2 cannot be moved to the locked or unlocked position unless the door is opened, so you may find it troublesome to operate it in rainy weather. was there.

A purpose of the present invention An object of the present invention is to provide a system that allows the child lock mechanism to visually check whether the child lock mechanism is locked or unlocked even when the door is closed, taking into account the current state of the conventional child lock mechanism for automobile doors as described above. The goal is to obtain a structure that can be confirmed.

Structure of the Invention In order to achieve this object, the present invention provides a vehicle door in which the child lock lever provided on the door lock is disposed in a part that cannot be operated from inside the vehicle when the door is closed. The present invention proposes that a display device be placed on the indoor side of the door to display the child lock lever lock/unlock position IE.

One Embodiment - Hereinafter, details of an embodiment of the present invention will be described with reference to FIGS. 1 to 3.

FIG. 2 showing an embodiment of the present invention is similar to FIG.
It is a perspective view similar to the figure, and the same reference numerals are given to the same structural parts as in FIG. 4. That is, the respective operation parts of the door lock 1 are connected to the outside handle 5, the inside handle 4, and the inside lock knob 3 via the rods 7.8.9, and the child lock lever 2 of the door lock 1 is used to close the door. A portion of the door inner panel 6, which is sometimes hidden by a rear seat or the like, is exposed to the inside of the vehicle. Therefore, in this structure, when the child lock lever 2 is in the "unlock" position, the door lock l can be locked and unlocked by switching the inside lock knob 3, and only when the inside lock knob 3 is in the unlocked position, the door lock l can be locked and unlocked. The door can be opened by operating the handle 5 or the inside handle 4. Furthermore, when the child lock lever 2 is in the "lock" position, the inside handle 4 and inside lock knob 3 are disabled, and the door can be opened only by manual operation of the outside handle 5. Inside handle 4
Even if the inside lock knob 3 is erroneously operated, the door is prevented from being opened inadvertently.

According to the present invention, a retractable child lock knob 10 is provided on the waist portion of an automobile door on the inside side of the vehicle, and this child lock knob 10 is linked to the above-mentioned child lock lever 2 of the door lock 1. As shown in FIG. 1, the child lock knob IO is connected to one end of a direction changing bell crank 12 via a rod 11, and the other end of the bell crank 12 is connected via a rod 13 to the child lock knob lO of the door lock 1. Since it is linked to 2,
When the child lock lever 2 is in the lock position, the child lock knob 10 is projected from the sieve plate 14 as shown by the solid line in FIG. 3, indicating that the child lock is not effective.

Since the automobile door according to the embodiment has the above-described structure, the child lock lever 2 can be "unlocked".
In its position, it can be used in the same way as a regular car door. That is, by locking the inside lock knob 3, dangerous opening of the door by the inside handle 4 while the vehicle is running is prevented, and the automobile door can be freely opened by unlocking the inside lock knob 3.

In the automobile door according to the present invention, it is possible to visually confirm whether the child lock mechanism is effective even when the door is closed.

When the child lock lever 2 is in the "Afro lock" position, the child lock knob 10 protrudes from the sieve plate 14 as shown by the solid line in FIG. 3, indicating that the child lock mechanism is not effective. When the child lock knob 10 is pressed as shown in the phantom line, the child lock lever 2 is switched to the "lock" position and the child lock mechanism becomes effective. When the child lock knob 10 is in the "locked" state, the child lock knob 10 cannot be picked out from the sieve plate, so erroneous operation by children etc. will not occur. Therefore, the switching state can be confirmed with the car door closed. At the same time, the child lock lever is activated by pressing the child lock knob 10.
Since the child lock knob 10 can be switched to the "lock" position, the child lock knob 10 can be switched to the "lock" position with a simple manual operation without worrying about the door being accidentally opened by a child or the like, and without having to open the door again. Can be switched to any position.

Effects of the Invention - As is clear from the above description, according to the present invention, a display unit linked to the child lock lever of the door lock is provided, so the switching state of the child lock lever can be checked even after the door is closed. This makes it extremely easy to operate. Further, according to the configuration of the above embodiment, the child lock lever can be set to "low" or "low" by only suppressing the child lock knob.
Since the door can be switched to the "back" position, there is no need to open and lock the door again, further improving operability.
