Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a door handle of a vehicle such as an automobile, particularly a back door.

(Prior Art) Conventionally, locking/unlocking mechanisms for vehicle doors can be broadly classified into the following two types, each of which has the following drawbacks.

The locking/unlocking mechanism is integrated with the door locking mechanism This type is used for front doors, and the locking/unlocking mechanism is built into the door locking mechanism.
Key cylinder (attached to the door, configured to operate the lock/unlock mechanism via a link mechanism by inserting the door key into the key insertion hole exposed on the outside of the door and rotating it) and locking button (door locking button) The locking/unlocking mechanism (located on the inside of the door) is operated manually via a link, which allows the door handle to swing idly or to release the door lock using the door handle. The disadvantage of this type is that since the locking and unlocking mechanism is integrated with the locking mechanism, there are many components, the structure is complex, and the cost is high.

The locking/unlocking mechanism is separated from the door locking mechanism. This type is used for sliding doors and back doors, and the locking/unlocking mechanism is separated from the door locking mechanism between the door handle and the door locking mechanism. The mechanism and door handle are connected by a control link. The disadvantages of this type are that the locking/unlocking mechanism and the door locking mechanism are separate, so the installation space becomes larger, and since the locking/unlocking mechanism and the door locking mechanism are connected by a link, it is less accurate than the previous type. is low and the cost is high.

(Purpose of the invention) This invention was made in view of the above-mentioned drawbacks, and has a locking/unlocking function. To provide a vehicle door handle which eliminates the need to provide a locking/unlocking mechanism separately from a door locking mechanism, thereby significantly simplifying the overall structure of the door locking device.

(Structure of the device) In order to achieve the above object, this device includes a base plate fixed to the door body, a handle body hinged to the base plate, one end of which is connected to the door lock mechanism, and the other end of which passes through the base plate. A connecting member is detachably attached to the handle body via a locking/disengaging mechanism, and one end is connected to a key cylinder, and when the key cylinder is unlocked, the connecting member and the handle body are engaged, and the key The present invention is characterized by comprising a link whose other end is connected to the locking/disengaging mechanism so as to release the engagement between the connecting member and the handle body by locking the cylinder.

(Example) Hereinafter, this invention will be explained based on drawings showing examples. Figures 1 to 3 show the first stage of this invention.
An example is shown. In the figure, a base plate 1 is fixed to a door body (not shown) with bolts 9, and the base plate 1 is provided with a hinge 1a. Reference numeral 2 denotes a handle body, which includes a hinge 2a, a hinge pin (not shown), and the hinge 1a.
It is hinged to the base plate 1 via. A cylindrical cable support fitting 7 is attached to the surface of the base plate 1 facing the handle body 2, and the cable 5 is slidably inserted through the base plate 1 into the inner hole 7a thereof. One end of the cable 5 is connected to a door locking mechanism (not shown), and a short column-shaped locking fitting 6 is attached to the other end. On the other hand, three guide members 1 are provided on the inner surface of the handle body 2 (the surface facing the base plate 1).
0 are arranged in an aligned manner, and the sliding portion 3a of the L-shaped slide member 3 is aligned in the direction of arrows P and Q (hinge 2
It is mounted so that it can move in the axial direction of a.
The bent portion 3b of the slide member 3 is provided with an arc-shaped elongated hole centered on the axis of the hinge 2a, and one end of the link 4 is connected so as to be movable within this elongated hole.
The link 4 extends in the axial direction of the hinge 2a at one end of the handle 2, and a key cylinder (not shown) is connected to the other end. By moving the sliding portion 3a in the directions of arrows P and Q, the short column-shaped locking fitting 6 and the sliding portion 3a of the sliding member 3 are connected to each other.
A T-shaped locking hole 8 is provided for locking and disconnecting.

In the above configuration, when the key cylinder (not shown) is locked, the slide member 3 moves in the direction of arrow P via the link 4, and the positional relationship between the locking fitting 6 and the locking hole 8 is as shown in FIG. Thus, the locking metal fitting 6 is in a state where it can be removed from the top portion 8a of the locking hole 8. When the handle body 2 is rotated in this state, the locking fitting 6 slips out of the locking hole 8 of the slide member 3, and the handle body swings in vain. The elongated hole provided in the bent portion 3b of the slide member 3 prevents the handle body 2 from rotating by connecting the link 4 to the slide member 3 at a position away from the axis of the hinge 2a of the handle body 2. to prevent

Next, when a key cylinder (not shown) is operated to unlock, the slide member 3 moves in the direction of arrow Q, and the locking metal fitting 6 engages with the small diameter portion 8b of the locking hole 8, as shown in FIG. When the handle body 2 is rotated in this state, the cable 5 is pulled through the locking fitting 6, and a locking mechanism (not shown) is activated to unlock the door.

4 to 6 show a second embodiment of this invention. Note that the same components as those in the first embodiment are given the same numbers and their explanations will be omitted. In the same figure, the handle body 2 of the base plate 1
As shown in FIG. 4B, a channel-type cable support fitting 17 is attached to the surface facing the
A guide groove 18 parallel to the axis of the hinge 1a of the base plate 1 is provided on the bottom surface 17a. In addition, the base plate 1 has a guide groove 1.
A guide hole 19 facing 8 is provided. A cylindrical sliding piece 20 engaged with the link 4 is in slidable contact with the cable support fitting 17, and the cable is guided through the inner hole 20a of the sliding piece 20 and the inside of the guide groove 18 and guide hole 19. 5 is slidably penetrated therethrough. One end of the cable 5 is connected to a locking mechanism (not shown) as in the first embodiment, and a locking fitting 6 is attached to the other end of the cable 5, as in the first embodiment. On the other hand, a channel-type engaging/disengaging member 13 is provided on the inner surface of the handle body 2.
A locking groove 14 parallel to the axis of the hinge 2a of the handle body 2 is provided on the bottom surface 13a. The locking groove 14 has one end open and the other end closed. The cable 5 slidably passes through the locking groove 14, and the locking metal fitting 6 is located within the locking/disengaging member 13.

In the above configuration, when the key cylinder (not shown) is locked, the sliding piece 20 moves in the direction of arrow P in FIG.
is the locking groove 1 of the locking/disengaging member 13 as shown in FIG.
It's out of 4. When the handle body 2 is rotated in this state, the handle body 2 swings in vain.

Next, when a key cylinder (not shown) is operated to unlock, the sliding piece 20 moves in the direction of arrow Q by the link 4, and the locking metal fitting 6 moves into the groove 14 of the locking/disengaging member 13, as shown in FIG. engage with. Therefore, when the handle body 2 is rotated, a lock mechanism (not shown) is operated to unlock the door.

It goes without saying that in the first and second embodiments described above, a rod may be used instead of the cable 5.

(Effects of the invention) As explained above, according to this invention, since it has a locking/unlocking function, a special locking/unlocking mechanism is not required, the overall structure of the door lock device can be simplified, and the cost can be significantly reduced. There are benefits to be gained.
