Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial application field) The present invention relates to an inside handle mechanism of an automobile door in which a latch mechanism of an automobile door and a handle mounted inside the door are linked.

2. Description of the Related Art Conventionally, various doors are mounted on an automobile depending on the application, but there is a vehicle in which a position of a handle for operating the door is different between an inside and an outside of a vehicle body. For example, as shown in FIG. 8, a door handle 4 is attached to an outer edge of a side door 3 which is attached to a vehicle body 1 via a hinge 2 so as to be openable and closable. As shown in the drawing, a remote control arm 6 is rotatably disposed on the latch body 5 arranged side by side with the door handle 4, and one end of a control rod 7 is connected to a front end of the remote control arm 6.
On the other hand, the other end of the control rod 7 is connected to an inside handle 9 rotatably provided on a base plate 8 fixed to the inside of the door. A lock mechanism 10 for locking the latch is provided side by side. The lock mechanism 10 is mounted on the base plate 8 with a sliding locking knob 11 attached thereto.
The locking arm 13 provided on the latch body 5 is operated via the locking rod 12. The shape and structure of the base plate 8 and the inside handle 9 are also disclosed in Japanese Utility Model Laid-Open No. 55-48510.

As shown in FIG. 9, the inside handle 9 is rotatably provided on the side of the vehicle body via a rotation shaft 14, and the tip of the control rod 7 is bent at a right angle to form a handle rear end 9a. It is inserted into the hole 15 and is rotatably locked. For this reason, when the inside handle 9 is rotated rearward (in the direction of arrow A) inside the vehicle cabin, the control rod 7 is pulled forward (in the direction of arrow B), thereby releasing the latched state of the side door 3. be able to.

(Issues to be solved by the invention) By the way, when the car is running or stopped,
Damage to the extent of contact with obstacles or other vehicles. As shown in FIG. 11, when an obstacle collides with the side door 3 from the side, the impact force in the lateral direction (in the direction of arrow C) is received, and the side door 3 is deformed and bent toward the passenger compartment. Alternatively, when a severe front collision occurs, the side door 3 may be deformed and bent in the vehicle interior direction. On the other hand, as shown in FIG. 11, the side door 3 is combined with a door inner panel 3a and a door outer panel 3b, and the control rod 7 for releasing the door latch is mostly disposed further inside the vehicle than the door inner panel 3a. Have been.

For this reason, when the side door 3 is deformed inside the vehicle, the control rod 7 is strongly tensioned. And
Depending on the degree of deformation of the side door 3, the tension is stronger than the play length of the control rod 7.
You will be strongly pulled. At this time, the end of the control rod 7 connected to the inside handle 9 is fixed and does not move to the center (the direction of arrow E), while the other end of the control rod 7 is used for releasing the latch. Since the remote control arm 6 is connected to the rotating remote control arm 6, the control rod 7 moves in the direction of arrow D by the stroke and rotates the remote control arm 6 in the direction of arrow F to release the latch. The impact force may cause deterioration of the control rod 7 and damage of the latch body 5.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an inside handle mechanism of an automobile door which prevents the door from being deformed by an external force at the time of a collision and preventing the latch from being released due to a strong tension of a control rod for latching a side door. And

(Means for Solving the Problems) In order to achieve the above object, the present invention connects a latch body for locking an automobile door and a handle mounted inside the door with a control rod, and operates the handle to operate the handle. In the mechanism for releasing the latch of the door by pulling the control rod, a handle is pivotally supported on a base plate mounted on the inside of the door, and an elongated hole is provided on the latch body side of the handle in a moving direction of the control rod. And a bent portion is formed at an end of the elongated hole on the rotation axis side, and when the handle is turned, a closed portion for holding an end of the control rod is formed by the bent portion and the base plate. It is characterized by the following.

(Operation) With the above configuration, in the normal case, when the handle is operated, the open side of the bent portion is closed by the base plate to form a closed portion when the handle is operated, and the end of the control rod is held. Further, since the closing portion also rotates with the rotation of the handle, the control rod is tensioned to move the latch main body, and the latched state of the automobile door is released. Further, when the automobile door is pushed inward and deformed due to sudden external force, the control rod is strongly tensioned, but the end of the control rod is disengaged from the bent portion and moves along the long hole to ease the tension. ,
The end of the control rod connected to the latch body does not move, and the latched state of the vehicle door can be maintained.

(Example) Hereinafter, an example of the present invention is described based on an accompanying drawing. As shown in Fig. 4, a base plate 17 is usually attached to a door inner panel 16 of an automobile side door.
18 or fixed with tapping screw.
A pair of upper and lower bearings 17a protrude from the base plate 17, and a rotating shaft 20 for rotatably supporting an inside handle 19 mounted therebetween is mounted on the bearing 17a in the vertical direction. A guide rail 17b for guiding the rotation of the inside handle 19 is formed on the door inner panel 16 side facing the bearing portion 17a, and the guide rail 17b
An arc-shaped guide wall 17c centered on the rotation shaft 20 is formed on a vertical surface of the shaft.

As shown in FIGS. 1 and 4, the inside handle 19 extends on both sides with respect to the rotation shaft 20 and has a handle rear portion 19 on one working side.
a is divided up and down to be supported by the guide rail 17b,
The guide rail 17b is inserted through this interval. The other extends in a curved shape to form a handle 19b. Here, the positional relationship among the bearing portion 17a, the handle rear portion 19a, and the guide rail 17b is arranged in the above-described order from the outside in the vertical direction as shown in FIG. The lower end of the rotating shaft 20 is engaged with a rotating shaft stopper 21 to hold the rotating shaft.

As shown in FIGS. 2 to 4, a long hole 19c is formed along the door inner panel 16 in the upper part and the lower part of the rear part 19a of the handle, and the long hole 19c is slightly near the rotation shaft 20 and slightly inside the vehicle. A bent portion 19d is formed. The tip of a control rod 23 bent at a right angle is fitted into a bush 22 slidably moving in the elongated hole 19c, and the bent portion is inserted into a rod holder 24 having an orthogonal hole to maintain the shape. . The other end of the control rod 23 is connected to a remote control arm 26 rotatably attached to the latch body 25 (see FIG. 6). Further, the bent portion 1 of the elongated hole 19c
9d is divided into a small space for holding the rod end in cooperation with the arc-shaped guide wall 17c of the base plate 17 (forming a closed portion). The tip of the control rod 23 is normally engaged near the bent portion 19d.

Next, the operation will be described. In a normal case, to release the latched state of the side door, the handle 19b is turned in the direction of arrow G shown in FIGS. In the range in which the rotation amount of the inside handle 19 is small, the elongated hole 19c has no binding force against sliding of the end of the control rod 23 in the elongated hole 19c.
Does not move in the release direction due to the presence of the spring force biased by the remote control arm 26 in the non-release direction.

When the inside handle 19 reaches a predetermined rotation amount, the elongated hole 19c is divided into a small space by the intersection with the guide wall surface 17c, and the sliding of the end of the control rod 23 can be restrained. And the remote control arm
When the inside handle 19 is rotated beyond the spring force urged by 26, the bush 22 to which the control rod 23 is attached moves smoothly along the arc-shaped guide wall 17c, and the control rod 23 is pulled. . Bend
If the stroke of 19d and the arc-shaped guide wall 17c are suitably connected, the backlash of the control rod 23 can be reduced.

As shown in FIG. 6, when an impact force K is applied to the side door, the control rod 23 is tensioned in accordance with the bent shape of the door inner panel 16, but as shown in FIG. The end of the control rod 23 is a long hole 19c
The latch body 25
The tension is not applied to the remote control arm 26 attached to the remote control arm 26, and the remote control arm 26 does not rotate. Therefore, the latch is not released.

Another embodiment will be described with reference to FIG. The difference from the above embodiment is that the rotating shaft 20 and the slot
17d is disposed, and the inside handle 19 is engaged with an end of a control rod 23 slidably provided in the long hole 17d by a hook 19e formed at the tip thereof. In this structure, the latch is of course not released even when the impact force K is applied to the side door as shown in FIG.

(Effects of the Invention) Since the present invention is configured as described above, the present invention is configured as described above, and the end of the control rod is formed into an elongated hole in normal times. The rod end is restricted by the closing portion by operating the handle, the latch body can be operated, and a normal automobile door can be opened and closed. Also, when the vehicle door is suddenly deformed inward by the impact force of a collision or the like and the control rod is tensioned strongly, the rod end moves through the elongated hole, and a force to release the latch is generated. The car door never opens. In addition, damage to parts due to the impact force is reduced.
